CROSS REFERENCE TO RELATED APPLICATIONS
FIELD OF THE INVENTION
[0002] The present invention relates to a chain mail and, in particular, to a chain mail
mesh configured as an anti-anxiety fidget device for reducing anxiety, fidgeting,
or stress type symptoms in humans. The present invention also provides a process employing
the chain mail mesh for reducing stress or inducing repeated use.
BACKGROUND
[0003] Stress and related human conditions are omnipresent and inevitable. Stress may be
caused due to dissatisfaction in the workplace and personal life. The world health
organization classified stress as the health epidemic of the twenty first century.
Stress may lead to grave physical health and mental health issues. Physical health
issues such as obesity and cardiovascular disease are on the rise. Mental health (a
silent killer) has been also linked to cause physical health issues. Mental health
issues such as autism spectrum, autistic, attention deficit hyperactivity disorder
(ADHD), Asperger's, anxiety, nervous breakdown, and the like are also of major concern
for all age groups.
[0004] Stress, whatever may be the cause, leads to a reduction in productivity at the workplace
and reduces the quality of life. It is estimated that only workplace stress costs
about $300 billion annually, in the United States alone, as a result of accidents,
absenteeism, and similar reasons.
[0005] It is of interest to reduce stress type conditions as well as to observe their pattern.
Attempts have been made in the past to develop devices and methods for reducing stress
especially suited for human use. The methods include various forms of meditation,
breathing exercises and the like. However, the devices and methods are somewhat unnatural
and do not go a long way. This is because a person employing such devices and methods
has to deliberately introduce these in his/her lifestyle and find time for the same
and hence is difficult to sustain. Physical tools and toys are also known, the fidget
spinner being probably the most popular.
[0006] Chain mail, also called chain mail, maille, or chain maille, was historically ring
mail used for defence against physical attacks. Scale mail was used for similar purposes.
Suits and other large areas of chain mail usually combined with a leather undergarment
reduced cuts and spread the force of blows from mainly edged weapons. Most of these
chain mail pieces were made by combining circular links made of wire formed and soldered
or riveted into links connected around other links. Typical weaves include European
(most commonly 4-in-1), Persian, and Japanese. Today, chain mail is still used by
butchers and others for cut resistance and other physical protection. They are not
sheets, other than some small pieces of such metal circular links and are also used
as pot scrubbers (e.g.,
US D702,009S) that have large circular wire links that are designed to be abrasive and do not
feel good against the skin. The weaves typically have more than one connection per
loop where each circle connects to at least three other circles in the same open circle.
Typical chain mail weaves ranged from 3-in-1 to 6-in-1, assembled in a variety of
patterns. None of these weaves feel calming against the skin, likely due to significant
non-planar rings, sharp edges, lack of flat surfaces, and other design elements focused
on protection and ease of manufacture with primitive tools.
[0007] While not the subject of this invention, one dimensional (1-D) chains are sometimes
called chain mail. These may be jewellery approximating historical chain mail elements.
Classic jewellery chains, ropes and bracelets are often also made of interconnecting
links, but these are very narrow and have a very high aspect ratio. These are designed
mainly to bend in limited directions around a neck or wrist. Some have a large tendency
to grab skin hair.
[0008] Typical weaves include box, byzantine, dragonscale, half Persian, helm, Jens Pind
linkage, spiral rope, roundmaille, etc. Watch bands made of links also differ from
the present invention in that they only bend in one direction. Also, these bands are
not usually wide enough to provide the intended interplay with the skin. Bike chains
and small fidget toys made from a small number of links also differ from the present
invention in that they are too small to drape over and contact enough area of skin,
only bend in one direction, or do not feel sufficiently smooth.
[0009] Recently some fidget toys, stress relief toys, and puzzles, advertise themselves
as chain mail or chain maille, but they have extremely limited motion. Unlike planar
chain mail, these are made into tight cubes, balls, infinity roses, and other highly
dense forms that like the very popular fidget spinners are designed to rotate links
rather than flex them. Some weaves include Mobioius, Turkish round, etc. They are
not sheets. None of these forms drape over any appreciable surface of skin and are
not designed for interplay with large areas of skin.
[0010] While wire links containing a single fully open planar loop are not part of this
invention, even the types of chain mail and prior uses of interconnected at least
partially rigid links with high flexibility between links are not designed for the
intended purpose of this invention, and while some may inadvertently approximate some
of this invention's advantages, they do not maximize the targeted physiological and
psychological effects induced by the use of this invention. They also generally do
not minimize the negative effects of historical chain mail, including ring mail and
scale mail, such as but not limited to vertical protrusions, pinching, grabbing hair,
smell, skin abrasion, excessive thickness, limited drape, limited flexibility, limited
range of motion, and limited contact area with the skin. Therefore, there is a need
for developing simple, inexpensive ways to reduce stress at the workplace and/or in
personal life.
BRIEF SUMMARY OF THE INVENTION
[0011] The present invention relates to a chain mail mesh and a process for reducing stress
type symptoms or inducing repeated use of the chain mail mesh in humans or providing
enjoyment by repeatedly employing the chain mail mesh disclosed herein. Stress reduction
may be accomplished by the impulsive repeated playing with the swatch of the present
invention.
[0012] In one aspect, the present invention provides a chain mail mesh for reducing the
stress in humans and improve general feeling of wellbeing, or when humans interact
with the chain mail mesh. The chain mail mesh, in accordance with the present invention,
comprises a plurality of interconnecting, polygonal links suitably interconnected
to define a sheet. The sheet is characterized by having a length (ML), a breadth (MB),
a thickness (MT) and weight (MW), which are suitably chosen to enhance the stress
reduction aspect. Each of the interconnecting, polygonal links have at least one degree
of freedom of movement in at least three directions, when not at the edge of the chain
mail mesh, with respect to its neighbouring polygonal links, are characterized by
a length (LL), a breadth (LB), a thickness (LT), and weight (LW) and have an operative
upper surface, an operative lower surface, and one or more substantially smooth edges.
The operative upper surface, the operative lower surface and the one or more substantially
smooth edges may have a shape selected from the group consisting of flat, concave,
convex, and any combinations thereof. In an embodiment, the interconnecting, polygonal
links are interconnected directly to the at least three neighbouring interconnecting,
polygonal links, directly or via an intermediate connecting member. For interconnecting,
polygonal links at the edge of the chain mail mesh, the interconnecting, polygonal
links may only be connected to two intermediate connecting members. The term flat
as used to define the contact area of the swatch, i.e., the area of the interconnected
links which come into contact with the skin of a user, for example, the skin of a
hand or fingers. An individual link not connected to other link is not measured because
it may have side or internal corners or surfaces not intended to significantly contact
the skin in the final swatch. Preferred measurement is percent external surface area
of the swatch or link, as measured by the percentage of link in the outer 10% of the
MT that may be felt by an adult hand when the swatch is at rest.
[0013] In one embodiment, the sheet may be rectangular or square in shape and may have about
5 to 20 interconnecting, polygonal links along the length and breadth independently
and allows the swatch to drape in more than one direction.
[0014] The sheet is configured to drape when contacted with or moved over, or combinedly
contacted with and moved over a human's body portion and substantially conforms to
the shape of the body portion, wherein the operative lower surface of the sheet in
contact with the body portion provides a calming, mood, or enjoyment effect when physically
interacting with a hand or other human's body portion. The thickness (MT) of the sheet,
when the sheet is in draped configuration, is different from the thickness (MT) of
the sheet when the sheet is placed on a substantially flat surface, where under at
rest (MT) is measured. The sheet has a predetermined drape coefficient. In an embodiment,
the drape coefficient is the same along the length (ML) and the breadth (MB) of the
sheet. In another embodiment, the drape coefficient is different along the length
(ML) and the breadth (MB) of the sheet.
[0015] In addition to length, breadth, and thickness, an acoustic spectrum may be generated
when the sheet is displaced by a user. Typically, the acoustic spectrum may comprise
one or more frequencies in the range of 20 Hz to 20,000 Hz. The sheet may be tuned
to a certain frequency band to provide a user with a relaxing and calming sound by
suitably choosing the material of make, the dimensions, the gap, and the structure
of the interconnecting, polygonal links and hence that of the sheet when in motion
during typical hand play.
[0016] Further, in the chain mail mesh, the interconnecting, polygonal links are interconnected
to at least three neighbouring interconnecting polygonal link, though links positioned
at corner or edges of the swatch may connect to at least one, and preferably at least
two, neighbouring interconnecting polygonal link, which combine to form an operative
upper surface and an operative lower surface of the sheet, wherein either of the operative
upper surface or the operative lower surface or preferably both are configured to
contact with at least a body part of a human, and provide a calming effect thereto.
More specifically, at least a portion of at least one of the operative upper surface
and the exposed link surfaces in operative lower surface of the sheet generally feels
smooth. The combination of this rigid pleasant surface with intermittent air gaps
and nonlinear motion produce a calming or enjoyment effect when contacted with or
moved over, or combinedly contacted with and moved over a human's body portion which
being apt to sense of touch. The interconnecting, polygonal links within the sheet
are spaced apart with a gap therebetween, which configures a loose hinge like configuration
between the interconnecting, polygonal links. Further, at least a portion of the sheet
which is bendable in at least one and preferably in both Z directions selected from
an operative upward direction of the operative upper surface of the sheet, an operative
downward direction of the operative lower surface of the sheet and a combination thereof.
The gap along with the loose hinge configuration and the provision of bendability
permits the sheet to drape when placed on a suitable support, very much like a piece
of fabric, though in a more nonlinear mechanism of motion. In addition to the bendability,
at least a portion of the sheet is skewable in at least one direction substantially
parallel to a plane of the sheet. In an embodiment, the gap is in the range of 0.1
mm to 7 mm, preferably 0.3 mm to 4 mm. For example, in a 10 cm x 10 cm swatch with
0.7 cm x 0.7 cm links, the links are made up of connector members with an average
thickness or diameter of 2 mm, a gap is 2.5 mm. The XY area of the gap is preferably
less than the XY area of the solid link, as measured by percent light transmission
through a swatch when the swatch is in a configuration with its smallest XY area on
a light table. Due to the rigid links and constrained motion, this means that the
sheet is not completely flexible and provides some resistance to drape in contrast
with a typical textile fabric.
[0017] In an embodiment, the periphery of the sheet may be terminated by employing polygonal
end cap links. The polygonal end cap links are connected to an outer most layer of
the interconnecting, polygonal links of the sheet. The number of layers or units of
the polygonal end cap links may vary. In an embodiment, the number of layers of the
polygonal links may be one. In another embodiment, the number of layers of the polygonal
links may be two or more. Preferably the polygonal end cap links may be the same as
that of the interconnecting, polygonal links. In one embodiment, the polygonal end
cap links may be different from that of the interconnecting, polygonal links, but
do not materially limit the drape of the swatch. The structure of the interconnecting,
polygonal links is chosen such that the operative upper surface, and/or the operative
lower surface of the interconnecting, polygonal links are generally smooth to touch,
thereby the operative upper surface and the operative lower surface of the sheet are
also substantially smooth to touch. In an embodiment, the interconnecting, polygonal
links comprises at least two lower horizontal connector members, which define the
operative lower surface and at least two upper horizontal connector members, which
define the operative upper surface, wherein the at least two lower horizontal connector
members being connected to the at least two upper horizontal connector members at
corner posts to define an incessant link.
[0018] In an embodiment, the interconnecting, polygonal links may further include at least
one lower transverse intermediate connector member disposed between and connected
to the at least two lower horizontal connector members and at least one upper transverse
intermediate connector member disposed between and connected to the at least two upper
horizontal connector members. The provision of the lower transverse intermediate connector
member and upper transverse intermediate connector member further enhances the smoothness
of the operative upper and the lower surfaces of the interconnecting, polygonal links
and that of the sheet and at the same time provides strength to the interconnecting,
polygonal links. In the preferred embodiment all members comprise the same type of
link.
[0019] In accordance with the present invention, the interconnecting, polygonal links and
the polygonal end cap links may be each independently manufactured from a material
selected from the group consisting of plastics, elastomers, thermoplastics, composites
metals, ceramics, and any combinations thereof. Plastics may comprise polymers including
thermosetting polymers, UV cured resins, thermoplastics, polyolefin homopolymers,
polyolefin copolymers, and the like. In an embodiment, the links may be covered with
a coating covering the surface of the links. For example, the coating may be a metal
coating, or a paint coating. The paint coating may be, for example, a polymer coating.
The metal may include metals and metal alloys. In an embodiment the metal may be an
aluminium alloy. Various non-precious metals may be coated using any suitable coating
method such as, for example, electroplating. Ceramics, metal composites, ceramic composites,
polymer-inorganic composites, or polymers may be metal coated or metal filled. In
one embodiment, gold, titanium nitride, or silver or other decorative or protective
coating may be employed.
[0020] The choice of the material depends on the drape of the sheet to be achieved, the
body portion over which the sheet is used, and the weight of the sheet to be achieved.
In an embodiment, the interconnecting, polygonal links and the polygonal end cap links
are each manufactured from plastic in the same production machine. In an embodiment,
the interconnecting, polygonal links and the polygonal end cap links are each co-dependently
molded from thermoplastic.
[0021] In an embodiment, the length (ML) and the breadth (MB) of the sheet are each independently
in the range of 50 mm to 250 mm, and the thickness (MT) of the sheet is in the range
of 3 mm to 8 mm, when the sheet is placed on a substantially flat surface, whereas
the length (LL), and the breadth (LB) of the interconnecting, polygonal links are
independently in the range of 10 mm to 20 mm. In a preferred embodiment, the X:Y ratio
of the sheet may be from 1:1 to 1:3, preferably approximately 1:1 for an approximated
square or circle of the same area as the swatch. It is noted that X and Y, or X, Y
are used herein to refer to the plane and sheet length and width of a swatch, respectively,
when at rest. X is also referred to as length (ML), and Y is also referred to as breadth
(MB).
[0022] In accordance with an embodiment, the interconnecting, polygonal links may have a
connection form that is at least one selected from the group consisting of a three-sided
polygonal link, a four-sided polygonal link, a five-sided polygonal link, and six-sided
polygonal link. The preferred connection form is to have loops on three or four sides
of the link in the X-Y plane. In an embodiment, the interconnecting, polygonal links,
while having void spaces, may have at least one overall, approximate visual shape
selected from the group consisting of a circle, triangle, a square, a rectangle, a
pentagon, a hexagon, versions of these with rounded corners, and combinations thereof.
In an embodiment, the interconnecting, polygonal links are square-shaped. In another
embodiment, the interconnecting, polygonal links are rectangular in shape. In another
embodiment, the interconnecting, polygonal links are generally cylindrical in shape
with optional protrusions or pillars. In an embodiment, the interconnecting, polygonal
links frame out a square shape in the X-Y plane, a flat top and bottom, same structure
as the other polygonal links, and a
(ML) and
(MB) generally similar and in the range of 10 mm to 18 mm and
(MT) in the range of 3 to 7 mm and are made of thermoplastic material.
[0023] The chain mail mesh, the interconnecting, polygonal links, and the end cap polygonal
links may be each independently manufactured by any known technique including, but
not limited to, 3D printing, injection molding, casting, snap fitting and combinations
thereof.
[0024] In another aspect, the present invention provides a method of reducing stress or
otherwise improving mental state in humans by contacting with and moving over, or
combinedly contacting with and moving over a human's body portion which being apt
to sense of touch, the chain mail mesh as described hereinabove, wherein the chain
mail mesh intermittently contacts near nerve endings of the body portion thereby provide
a calming or other positive effect thereto.
[0025] In an embodiment, a device including a flexible swatch is provided wherein the flexible
swatch is a chain mail mesh formed of flexible interconnecting links suitably interconnected
to form a sheet, preferably a single layer sheet. Each of the interconnecting links
has a polygonal shape when viewed from the top and comprises:
at least two lower horizontal connector members;
at least two upper horizontal connector members;
at least one lower transverse intermediate connector member disposed between and connected
to said at least two lower horizontal connector members; and
at least one upper transverse intermediate connector member disposed between and connected
to said at least two upper horizontal connector members,
wherein said at least two lower horizontal connector members along with said at least
one transverse intermediate connector member define an operative lower surface of
said interconnection polygonal link,
wherein said at least two upper horizontal connector members along with said at least
one transverse intermediate connector member define an operative upper surface of
said interconnection polygonal link,
wherein said at least two lower horizontal connector members being connected to said
at least two upper horizontal connector members at corner posts to define an incessant
link,
wherein each of said interconnecting polygonal link is made of thermoplastic material
and having a length and a breadth in the range of 10 mm to 14 mm, independently,
wherein each of said interconnecting polygonal links being similar in structure, dimensions,
and shape,
wherein each of said interconnecting links is interconnected to at least one neighbouring
interconnecting polygonal links combine to form an operative upper surface and an
operative lower surface of said sheet,
wherein the number of interconnecting links being in the range of 5 to 15 along the
length and the width of said sheet independently,
wherein said sheet is either having a substantially rectangular configuration or a
substantially square configuration wherein said sheet is laid on a flat surface,
wherein at least a portion of at least one of said operative upper surface and said
operative lower surface of said sheet generally feels smooth, which produce a calming
effect when contacted with or moved over, or when contacted with and moved over a
human's body portion which being apt to sense of touch, and
wherein said sheet includes at least one layer of polygonal end cap links connected
to an outer most layer of said interconnecting polygonal links of said sheet, said
polygonal end cap links being same as that of said interconnecting polygonal links
or said polygonal end cap links being different from that of the interconnecting polygonal
links.
[0026] The links may in a specific embodiment may have a rectangular, or square shape and
the overall chain mal mesh may be a rectangle, square, circle or oval.
[0027] In still another aspect, the present invention provides a process for reducing stress
or otherwise improving mental state in humans, the process comprising the steps, including
holding the chain mail mesh, in one or both hands of a human, contacting the chain
mail mesh with a body portion of the human and/or moving the chain mail mesh over
the hand or other body portion of the human such that the lower operative surface
and the upper operative surface contacts with nerve endings of the body portion and
thereby provide a calming effect thereto, and repeating the above steps more than
once to reduce the stress in humans.
[0028] The body portion is the general skin and nerve ending region, which is approximately
and partially contacted with and over which the chain mail mesh is moved over time.
Preferably the body portion is at least one selected from the group consisting of
hand, wrist, head, forehead, shoulder, back, chest, neck, finger, calf, knee, thigh,
hip, waist, foot, heel, ankle, buttock, leg, skin, and stomach and is not limited
to these movement method incudes physical interaction of a subject with the swatch,
and optionally visual and auditory senses. The preferred body portion is fingers and
portions of the hand. Because the swatch of links provides feelable solid and air
combinations and textures that at least nonlinearly change with motion, the resulting
effect on the subject differs from that of typical textiles. These intermittent skin
contact physical senses then lead to mental and central nervous system (CNS) effects.
These resulting effects on the subject may be used to both directly affect the anxiety
or other mood of the subject or as an external indicator or the subject's mood in
applications such as psychological therapy, interviews, interrogation, lie detection,
and the like.
[0029] In an embodiment, a method of reducing stress in humans is provided the method comprising:
placing the device of claim 1 on a body portion of a human which is apt to sense of
touch, and moving the device over the body area, wherein said device intermittently
contacts skin areas near nerve endings of said body portion thereby providing a calming
effect thereto. The method may further comprise holding the device in a hand, contacting
said chain mail mesh with a skin portion of said hand and moving said chain mail mesh
over said skin portion such that at least one of said lower operative surface and
said upper operative surface stimulates nerve endings of said skin portion and thereby
provide a calming effect thereto, and repeating the above steps. The user may move
at least some of their fingers over the lower or upper surface or both to feel the
relief pattern formed by the combination of gaps and smooth surfaces, and the user
may move the chain mail mesh in three dimensions to maximize changing contact with
their skin. The user may move the chain mail mesh from hand to hand.
[0030] For example, the method the body portion may be a first hand of the human, and the
human may be holding the chain mail mesh with a second hand, contacting the chain
mail mesh with a skin portion of the first hand and moving the chain mail mesh over
the skin portion of first hand such that at least one of a lower operative surface
and an upper operative surface stimulates said nerve endings of said skin portion
thereby inducing the human to increase rate or frequency or both of motion of the
chain mail, and observing such visually, audibly or both.

DETAILED DESCRIPTION OF THE INVENTION
[0034] All technical terms and scientific expressions used in the present invention have
the same meaning as understood by a person skilled in the art to which the present
invention belongs, unless and otherwise specified. As used in the present specification
and the claims, the singular forms "a", "an" and "the" include plural references unless
the context clearly dictates otherwise.
[0035] The term "comprising" as used in the present specification and the claims may be
understood to mean that the list following is non-exhaustive and may or may not include
any other extra suitable things, for instance, one or more additional feature(s),
part(s) and /or constituent(s) as applicable.
[0036] Further, the terms "about" and "approximately" used in combination with ranges of
sizes of parts, particles, compositions of mixtures, and/or any other physical properties
or characteristics, are meant to include small variations that may occur in the upper
and/or lower limits of the ranges of sizes.
[0037] Swatch or Chain mail or chain mail mesh is defined herein to mean a fabric of interconnecting
rigid links, wherein the links are large enough to be individually felt by human fingers
or any body parts and their connection flexible and loose enough to drape the fabric
over a body part of a human, for example, a hand of a human.
[0038] Rigid link means the link has a stiffness or flexural modulus of at least 1.5 GPa,
as measured by ASTM D790 and ISO 178 bend test method.
[0039] Stress as this term is employed herein may also include other human conditions, symptoms,
and manifestations of mind, body or both that cause a human to feel less than happy.
[0040] Smooth surface or edge refers to the texture of a surface or edge which feels generally
smooth to the human touch and is substantially free of sharp edges or profiles.
[0041] Loose hinge or loose loop as used herein means a coupling or a connection between
two adjacent interconnecting, polygonal links and/or an interconnecting polygonal
link and a polygonal end cap link and/or between an interconnecting polygonal link
and an intermediate connecting member, wherein the coupling or connection is similar
to a hinge in allowing constrained motion, but is loose thereby enabling relatively
free movement of the interconnecting, polygonal links, polygonal end cap links and
intermediate connecting member as compared to conventional hinges. Free movement means
both looseness or rattle, and movement outside of the single rotational direction.
Loop is a functional description of this loose connection means. As a hinge has loops
and a pin, the links have constraining closed loops or partially constrained loop
sections that constrain loops of portions of neighbouring interconnecting, polygonal
links. A loop may also comprise integral structural parts of the interconnecting,
polygonal links.
[0042] Neighbouring interconnecting, polygonal links may include an immediate neighbouring
interconnecting polygonal link or may also include a connecting link between such
interconnecting polygonal links.
[0043] Skewable as this term is used herein means that the sheet and/or the chain mail mesh
may be at least slightly distorted at least either lengthwise or breadthwise or both
by moving the interconnecting, polygonal links and/or the polygonal end cap links
and/or the intermediate connecting members.
[0044] The at rest state or XY area of the swatch refers to the area defined by the swatch
perimeter in the X-Y plane when the swatch is placed on a flat, hard surface on the
X-Y plane, gently pulled out to its maximum area, and released to rest on the flat,
hard surface.
[0045] Link looseness refers to the play between the loop and the adjoining link. For example,
loops have at least one inner dimension that is larger than the connecting link part
in that loop to allow some play in the motion between the link with the loop and the
connecting link. This play may often allow features such as fast motion, looseness
in motion, noise of rattles or jangles, as compared to a limited motion device such
as a door hinge.
[0046] Resistance to motion may limit the motion of the neighbouring links and of the swatch
in aspects such as direction of motion, limit of motion, speed, acceleration, friction,
and the like. It is mainly controlled by link location, link shape, link looseness,
and collision between adjacent link may constrain maximum range motion.
[0047] Drapability also referred to herein as drape is the ability of the swatch to significantly
flex such that at least a majority of the XY edges of a swatch to bend at least 65
degrees from the X-Y plane when placed on a circle with a diameter at least 1.5 times
that of the average diameter of the largest link in that swatch. While not optimal
for composite nonlinear materials, this may be measured by a Drapemeter under the
British standard for the assessment of drape of fabrics (BS 5058) where the ratio
of the projected area of the chain mail mesh to its undraped area, in which the area
of a supporting disk is deduced. The sample may be the swatch rather than the small
sample the standard uses for typical textile fabric. Preferably, the unsupported area
may drape to form some at least partial folds. The number of the folds (nodes) is
used to describe the drapability directly. The more the nodes, the softer is the fabric.
The drape coefficient is the ratio of the projected area of the fabric sample to its
undraped area, in which the area of the supporting disk is deduced. High drape is
desired unlike chain mail and other armor where high drape reduces physical protection.
[0048] The drape coefficient of composite textiles is generally more difficult to measure
than traditional textiles. An objective method for the determination of fabric samples
mechanical properties is known as the "jutting strip method" or "cantilever method"
which has been developed by Pierce in 1930 and is included in the FAST system (Fabric
Assurance by Simply Testing). The bending property, making a part of the overall mechanical
characterization of the swatch may be correlated to a drapability. See,
Smart Textiles for In Situ Monitoring of Composites, Vladan Koncar, Woodhead Publishing,
Oct 29, 2018 - Technology & Engineering, p. 218. For simplicity, this invention measures both drape and drape coefficient as the
minimum deflection in the Z direction of a swatch in the X-Y plane. A plastic swatch
may have a smaller radius of drape, where drape will not substantially differ over
a wire, or measurement circle of up to 0.5 cm because it typically will have larger
links. A metal swatch due to mechanical strength can have smaller links and smaller
connecting means than plastic and, therefore, would have a larger drape because while
still a composite, it can move in a manner closer to that of a traditional non-composite
textile. The inventive swatch may be able to both generally lay flat on a flat hard
surface and roughly drape over a 3D shape such as a hand or ball, though the link
size and swatch flexibility may usually not touch the entire 3D shape.
[0049] The present invention uses a sheet of flexible links, herein defined as a swatch.
While the applicant uses the term chain mail, the current invention does not use traditional
ring mail weaves of wire or sharp-edged loops or large protective garments. Rather
the links and the swatch are designed to provide several important physical attributes
to maximize enjoyment or satisfaction of a user playing with that swatch.
[0050] The swatch of this invention has a very particular type of segmented motion due to
link spacing and connection means, unlike a completely flexible cloth or thin silicone
elastomer sheet. The direction of motion is constrained in that the swatch bends in
more than one direction, but by a nonlinear method. The motion is not necessarily
simultaneous in all directions or linear at all swatch conformations. For example,
the swatch may simultaneously bend in multiple directions to increase hand contact
and variety of contact.
[0051] The term swatch as used in this disclosure refers to the chain mail sheet that comprises
the links and has the size, and flexibility designed to impart the psychological and
physiological effect on the user. It is predominantly defined by X (ML), Y (MB) and
Z (MT) dimensions, but to maximize intended psychological benefits, also requires
specific combinations of ranges of link size, flatness, weight, flexibility and mode
of motion. Flexibility is defined as the ability to bend without excessive force such
that at least three non-adjoining links can touch.
[0052] When placed on a flat hard surface, on the X-Y plane, gently pulled out to its maximum
area, and then released, the swatch is herein defined to be in its at rest state,
and comprises at least a majority and preferably all or almost all of the following
attributes:
- A) The general swatch shape may have an aspect ratio no greater than an equilateral
triangle or otherwise approximate no more than a 1:4 X:Y ratio, preferably less than
a 1:1.33 X:Y ratio. In the Z direction, the shape should give the swatch a look of
a roughly approximate sheet when at rest with the totality of the links, not counting
voids, averaging two parallel surfaces that encompass the operative upper surface
and the operative lower surfaces. In an embodiment the two parallel surfaces may differ.
In an embodiment the swatch may approximate in the X-Y plane the shape of a circle,
ellipse, triangle, rectangle, square, rectangle, pentagon, hexagon, octagon, or any
combinations thereof. In a preferred embodiment, the swatch shape in the X-Y plane
may be a square or a square with missing corner pieces. In another embodiment the
swatch shape in the X-Y plane may be an ellipse. In a particular embodiment the swatch
shape in the X-Y plane may be a circle.
- B) The shape of the link is mainly limited by the loop or other connection means location
to determine direction of bend and how the shape of the link and the loop constrain
the direction and extent of motion with the adjacent links and therefore the overall
swatch. In an embodiment shape may be determined by performance to cost, manufacturing,
packaging or aesthetics.
- C) The swatch's shape when taken to approximate an ellipse or rectangle may have an
X-Y aspect ratio within 1:1 to 1:4.
- D) When at an at rest state, the swatch X-Y area may be from 10 cm2 to 1,000 cm2, preferably from 20 cm2 to 500 cm2, more preferably from 15 cm2 to 500 cm2, and most preferably from 25 cm2 to 400cm2. In an embodiment, the swatch may approximate a square or square with chamfered corners
with a length and width within the range of 6 cm to 10 cm. In another embodiment,
the swatch may approximate a circle with a diameter from 3 cm to 10 cm.
- E) The swatch may be highly flexible. In an embodiment at least one edge of the swatch
sheet should be able to touch the opposite XY side of the swatch when the swatch is
freely bent, in its two most flexible directions, over a rigid rod with a diameter
of less than 3 mm.
- F) The swatch may bend in multiple directions so that it has sufficient drape that
it may at least loosely drape over at least one of a Reuleaux tetrahedron, rounded
tetrahedron, ellipsoid or hemisphere with a maximum diameter or edge of 5 cm and surface
area of less than the swatch XY area. In one embodiment the swatch may be easily crumpled
in three dimensions to change from a X-Y sheet to a 3D structure with a Z dimensiuon
of at least 3 times that of the sheet's MT.
- G) The swatch may be sufficiently loose such that it may bend under its own weight.
- H) The swatch may have some give. By give as this term is used here we mean that the
width of the gaps formed at the top operative surface or at the bottom operative surface
may be increased or reduced by the user because the interconnecting links are loosely
connected allowing a link to move in the X or Y direction relative to its neighbouring
link. This movement or give in the X-Y plane may result, for example, that the preferred
minimum X-Y area may be within 70% to 96% of the at rest area. The at rest area is
also referred to herein as a maximum area.
- I) The swatch may comprise flat or approximately flat external surfaces available
to touch.
- J) The swatch should not have uncomfortably sharp edges or sharp protrusions.
[0053] The swatch thickness (MT) is within 1 mm to 10 mm and preferably within 2 mm to 7mm.
The thickness of the swatch (MT) may be sufficiently large for preventing formation
of sharp surfaces and for allowing human touching and perception of individual links,
but not so large as to impede the intended motion, looseness, and drape of the swatch.
A preferred thickness may partially be dependent on the material weight and strength.
For example, a stronger material, e.g., metal, may provide the required strength for
thinner walled loops and, therefore, thinner swatches.
[0054] The swatch may be made of at least one type of link, meaning that all the links are
of the same shape and size. However, more than one type of links may be used. In an
embodiment 2-3 types of links may be used. In a preferred embodiment one type of link
is used.
[0055] In an embodiment, the swatch may have a polygon such as a triangle, a square etc,
with a plurality of swatch's corners. In another embodiment, the corners may be eliminated
because from an operational perspective they may be too sharp, droopy, loose, or unconstrained.
[0056] Each link in the swatch, other than optionally corner links, may be connected to
at least three other links. In a preferred embodiment, each corner and edge link may
be flexibly connected to 2-4 other links, and each other link may be flexibly connected
to 3-6 other links, and preferably to 3-4 other links. The preferred embodiment has
3 or 4 connection means per link generally forming a triangle or square from the flexible
connection perspective, while visually the link may approximate other shapes described
herein.
[0057] In an embodiment, additional links with different flexibility or lack thereof that
may provide additional functionality such as LED light, sound, color, and the like,
may be employed in addition to the flexible links. Preferably, link types may be less
than 9, more preferably less than 5, and most preferably less than 2.
[0058] The swatch may have an overall macro roughness that is greater than that of a woven
textile fabric but significantly less than a traditional ring chain mail mesh. In
other words the swatch may have an overall macro smoothness that is less than that
of a woven textile fabric but significantly more than a traditional ring chain mail
mesh. The present invention achieves this by employing generally flat external surfaces
and a sufficiently large ratio of touch surfaces to the total area covered by the
swatch. These touch surfaces combined with a smaller percentage of void space are
present in both in a flat X-Y sheet form as well other conformal forms of the swatch.
[0059] The swatch may have a flatness wherein 5-90%, preferably 20-90%, more preferably
40-90% and most preferably 60-90% of the touchable surface (also referred to as the
contact area of the swatch) of the top side and optionally the top and bottom side
is flat. The contact area of the swatch is the area of the interconnected links which
come into contact with the skin of a user, for example, the skin of a hand or fingers.
An individual link not connected to other link is not measured because it may have
side or internal corners or surfaces not intended to significantly contact the skin
in the final swatch.
[0060] The swatch may have a sufficient solid coverage such that when the swatch rests on
a flat surface and in smallest contracted size without continuous external applied
force, at least some portion of the swatch covers 20% of the X-Y plane, preferably,
at least 25%, and, more preferably, at least 33% of the X-Y plane. This coverage is
best measured by placing the swatch at rest on a flat light table and measuring the
reduction in transmitted light. Ring mail and other link forms with large extremities
but small material cross-section may not provide this coverage.
[0061] The volumetric density (in XYZ space) may affect important aspects of the swatch
and its use such as but not limited to weight, feel, and looseness. Volumetric density
may also be used as a method to measure such properties, but is defined to describe
the general swatch and not the link material or material porosity within the link.
For a swatch made of plastic interconnecting links, the preferred volumetric density
when contracted or at rest, is 20 to 50 vol% and preferably 30-40 vol%. Some designs
that do not stretch significantly in the XY plane, may require more volumetric stretch
to ensure sufficient flexiblity.
[0062] The swatch may preferably consist of one layer of links, though some embodiments
may have 1-3 layers of chain or a combination of main links and loose, highly flexible
connecting means such as loops, thread, fiber, fabric or sheet included in these layers.
[0063] The swatch may have an aesthetic look that includes at least one of a colour, a surface
printing, a coating, a painting, and a pattern of coloured links. Some of these treatments
such as coating may be multifunctional, e.g., also affect feel and motion.
[0064] The swatch may not have rigid frames that impede intended flexibility and drape.
The swatch may optionally have differing edge links. The swatch may, for example,
be generally uniformly flexible along the swatch, with the same type of link or links
throughout the swatch, though such links on the edge may naturally have less support
from other links and may be more pendent. Although different types of interconnecting
links may be used, a preferred link may have sufficient complexity and volumetric
coverage. A preferred link may not be a simple circle or loop. A preferred link may
have at least twice the contact with a flat surface than does a chain mail made of
wire loops.
[0065] The links are the discrete parts that make up the swatch and also have very specific
requirements in order to impart or maximize the beneficial interactions with the user
during intended use of this invention.
[0066] The maximum dimensions of a link are X or length (LL), Y or, a breadth (LB), and
Z or a thickness (LT). The size partially depends on the material. For plastic, the
preferred LL and LB are within 0.3 cm to 2.5 cm. For a square, rectangle, or version
thereof without corner links, the preferred LL and LB are within 1.1 cm to 1.5 cm.
For triangular, LL (base) and LB (base to apex) are within 1 cm to 2 cm, and preferably
within 1.2 cm to 1.7 cm. Large links, e.g., links having sides > 2 cm are not preferred.
[0067] The thickness Z or (LT) defines overall maximum thickness (Z) between upper surface,
and lower operative surfaces. LT is proportionate to weight. For plastic LT may be
within 3.5 mm to 20 mm, and preferably within 4 mm to 10mm. For metal LT may be within
0.5 mm to 10mm, and preferably may be within 0.6 mm to 7mm. An embodiment has an LT
of 3-4 mm. LT may not be too thick or it may not feel as pleasant and often may interfere
with flex and drape.
[0068] The movement area is defined in the Z direction as LT minus the maximum link thickness
or diameter in any XYZ direction of the top minus the maximum link thickness or diameter
in any XYZ direction of the bottom v during motion (e.g., a rectangular cross-section
may be thickest at 45 degrees). This movement area must allow free motion of the swatch
in the intended directions and intended range of motion, though it may create friction,
otherwise slow, or stop motion in other directions depending on the swatch conformation
at the time.
[0069] The link may have a shape which approximates in the X-Y plane a circle, an ellipse,
a triangle, a rectangle, a square, a pentagon, an hexagon or an octagon. The link
may have a shape having an X:Yor ML:MB aspect ratio no greater than 1:2, preferably
less than a 1:1.33. While it is rather easy to measure for a rectangle or ellipse,
other shapes such as an equilateral triangle for example would also fall within this
ratio. In the Z direction, the shape of the link may provide significant smooth feeling
surface to the touch. The top and bottom surfaces of the link may be identical in
terms of smoothness, shape, and size, although their orientation may differ as, it
is shown, for example in the embodiment of FIG. 2C. However, in other embodiments,
the top and bottom surfaces of the link may differ not only in orientation but, also,
in at least one of smoothness, shape, and size. For example, in an embodiment the
bottom surfaces of the link may be substantially flat while the top surfaces may include
a flat portion and a curved portion. Preferably, the shape of the link from a top
or bottom view (i.e., in the XY plane) may be a square, a triangle, or a modified
square or triangle having their corners smoothed out. Link shapes that are pentagons,
or hexagons are less preferred because of the larger number of connection means required
which increase the complexity of the design. The connection means may preferably be
3 or 4 per link. The link may be formed to include a plurality of at least one of
the following types of elongated elements including beams or rods having a circular,
oval, or rectangular cross section. For example, the elongated elements may include
a straight cylinder, a bend cylinder, a straight beam, a bend beam, a twisted cylinder,
a twisted beam pillars, and other rods that are configured to provide the desired
general shape of the link and have at least a portion thereof being flat or substantially
flat surface in the XY plane. For example, in an embodiment, the elongated element
may have an XY plane surface that is a combination of a flat and a curved surface.
In an embodiment, the link may have a Cuban chain link shape significantly modified
to connect and flex in a 2-D sheet. In a preferred embodiment, the swatch is a square
or a square with missing corner pieces. The shape of the link may also be a square
or a square with missing corner pieces. The shape of the link is mainly limited by
the loop location that determines bend direction and how the shape of the link and
the loop constrain the direction and extent of motion with the adjacent links and
therefore the overall swatch. In an embodiment the loop is the link. Sharp corners
are also to be rounded or minimized when they may provide an uncomfortable sensation
by the user.
[0070] A Loop is the part of the link that holds an adjoining link and allows generally
free motion of that adjoining link in a constrained direction. A link may be merely
the space between posts. A loop is defined as the physical or functional method of
loosely coupling links. Rigid hinges are not contemplated. Single wire loops or other
similar single simple circles or ovals without significant contortion and wall thickness
are not contemplated other than in swatches with at least two link types where the
circle serves as a connecting link, and that connecting link is generally shielded
from the skin in most swatch configurations by the other type, non-circle links. More
complex link shapes may contain circle or loop elements such as two at least partially
flattened circles connected by posts or loops. A loop may be combination (e.g., pillars
in center, loops on outside to retain "smooth" feel during motion. Loops may be at
least partially coated to modify feel or to apply friction to motion. For example,
there may be only one connection per loop, though the loop may be defined by position
or other constraints to motion than a completely closed loop. Concave Curb Cuban link
chain and Miami Cuban Link Chain are one-dimensional examples incorporating such a
link that contains only one opening but functionally defines three loops. The walls,
pillars, freeform enclosure, or other link parts defining the loop may be strong enough
to withstand repeated play without application of force beyond the swatch weight.
[0071] All or a majority of the X-Y plane areas of the links may have a flat or substantially
flat portion of their externally facing surface area of the link's external upper
surface and lower surface. Substantially flat includes small deviations from flat
due to manufacturing limitations, intentional inclusion of edge chamfer or fillet,
and intentional inclusion of smooth protrusions that impart roughness. In a preferred
embodiment, both the top side and the bottom side have identical flat or substantially
flat surfaces. In an embodiment one of the top or bottom sides comprise non-overlapping
plates sufficiently separated to allow the intended range of motion in at least one
Z direction.
[0072] The links may preferably be rigid. For example, rigid links made of a polymer material
such as a thermoset or thermoplastic material or metal may be used for the swatch.
The links may be coated with a metal or polymer coating. For example, the coating
may be an elastomeric or a coloured coating.
[0073] Higher weight and therefore higher density of links are preferred. Links may be solid
or have a porosity of less than 50 vol% as compared to the solid coverage of the swatch.
Higher density is preferred within a range of from 0.5 g/cm
3 to 10g/cm
3, 0.8 g/cm
3 to 1.55 g/cm
3 for plastic, 2.5 g/cm
3 to 8 g/cm
3 for metal, and 1 g/cm
3 to 8 g/cm
3 for composite or coated links such as, for example, metal coated metal or plastic,
plastic or metal coated metal. The preferred mode uses an inexpensive, easily manufacturable
material such as a plastic material or cast metal, e.g., plated or coated zinc casting.
[0074] The links may not have any sharp external edges that would be touchable in normal
swatch conformations and draped forms. Any touchable edges may be preferably rounded,
with a chamfer, fillet, coating or other softening or removal technique. This does
not mean that the swatch may be completely smooth. The interplay between hard surfaces
and spaces in between in a range of 3D motion is necessary for this present invention's
use. In a preferred embodiment, the links are rounded with flat or substantially flat
profile on both external XY plane surfaces. The inside part of the link that is not
normally touchable is not important as far as roughness, sharpness and finish other
than in how it adversely affects rate of motion or noise of the swatch.
[0075] The operative upper (top) surface and operative lower (bottom) surface are connected
by vertical connections between top layer and bottom layer. The number of posts or
other such connections may vary between 3 and 8, preferably between 3 and 7, and more
preferably either 5-7 or 3-6. The posts may have varied forms such as but not limited
to pillar, curved, loops, free forms connecting top and bottom. Links may have a mix
of posts, angled posts, and other types of vertical connections (e.g., curved). In
an embodiment there are no posts and a thread or fiber may connect the links. In an
embodiment links may also comprise or simply contain one or more highly bent loops.
[0076] The terms such as flat and substantially flat surface, includes completely flat and
approximately flat surfaces, which are not completely flat. An operative upper surface
and operative lower surface includes surfaces that are or appear to be upper and lower
respectively when in use.
[0077] The present invention is now described hereinbelow with reference to the accompanying
drawings, wherein FIG. 1 illustrates an isometric view of a chain mail mesh of the
presently disclosed invention, wherein the chain mail mesh is in the form of a sheet,
with square end cap links and with identical square-shaped interconnecting, polygonal
links, FIG. 2A illustrates a side view of an interconnecting polygonal link in accordance
with an embodiment of the present invention, FIG. 2B illustrates another side view
of the interconnecting polygonal link of FIG. 2A, FIG. 2C illustrates a perspective
view of the interconnecting polygonal link of FIG. 2A, FIG. 3A illustrates a perspective
view of a pair of interconnecting, polygonal links of FIG. 2A, wherein two interconnecting,
polygonal links (having a square shape) are connected together, FIG. 3B illustrates
a top view of the pair of interconnecting, polygonal links of FIG. 3A, FIG. 4A illustrates
an isometric view of an interconnecting polygonal link in accordance with another
embodiment of the present invention, and FIG. 4B illustrates a top view of a pair
of interconnecting, polygonal links of FIG. 4A, wherein two interconnecting, polygonal
links (having a square shape) are connected together.
[0078] The present invention provides a chain mail mesh 100 which when employed by a human
suitably, leads to a significant reduction in stress. Typically, the chain mail mesh
100, when contacted with and/or moved over a body part (such as, for example the skin
of the top part of a hand) of the human provides a soothing effect to the body part.
Also, the chain mail mesh 100 functions as an anti-fidgeting device that engages the
attention of a human and releases its anxiety and stress by the repeated use of the
chain mail mesh. The chain mail mesh 100 (FIG. 1) of the present invention is different
from those encountered in the prior art. For example, FIG. 5 illustrates a conventional
chain mail mesh having ring-shaped interconnecting links and made of metal. The conventional
chain mail mesh of FIG. 5 has a very bumpy surface and is not at all smooth. By contrast,
the chain mail mesh 100 has relatively smooth contact surface(s) imparted by the flat
or substantially flat surfaces of the employed links in the external top and bottom
XY plane surfaces, which when contacted with and/or moved over a body part (such as
the skin of a hand) of the human, has a much higher contact area with such body part
and a much smoother and pleasant texture (or feel), thus providing a soothing effect
to the body part.
[0079] More specifically, in accordance with an aspect of the present invention, a chain
mail mesh 100 in the form of a sheet 102 is illustrated in FIG. 1, wherein a plurality
of interconnecting, polygonal links 104 are interconnected to define the sheet 102.
The chain mail mesh 100 comprises the interconnecting, polygonal links 104 suitably
interconnected to define the sheet 102. The sheet 102 has a predetermined length (ML),
a predetermined breadth (MB), a predetermined thickness (MT) and a predetermined weight
(MW). Each of the interconnecting, polygonal links 104 have at least one degree of
freedom of movement in at least one direction with respect to its neighbouring polygonal
links and have a length (LL), a breadth (LB), a thickness (LT) (FIG. 2C), and weight
(LW). Further, each of the interconnecting, polygonal links 104 are interconnected
to at least one neighbouring interconnecting polygonal link 104, which combine to
form an operative upper surface 102A and an operative lower surface 102B of the sheet
102. At least a portion of at least one of the operative upper surface 102A and the
operative lower surface 102B of the sheet 102 are configured to be flat or substantially
flat such that they generally feel smooth, which can produce a calming effect when
contacted with or moved over, or combinedly contacted with and moved over a human's
body portion which is apt to sense of touch. In an embodiment, the interconnecting,
polygonal links 104 may be interconnected to the at least one neighbouring interconnecting
polygonal link directly. In another embodiment, the interconnecting, polygonal links
104 may be connected to at least one neighbouring interconnecting polygonal link via
an intermediate connecting member (not shown in the figures).
[0080] In accordance with an embodiment of the present invention, the length (ML) and the
breadth (MB) of the sheet 102 may be independently in the range of 50 mm to 250 mm,
and the thickness (MT) of the sheet may be in the range of 1 mm to 25 mm, preferably
in the range of 10 mm to 14 mm, when the sheet is placed on a substantially flat surface,
whereas the length (LL), and the breadth (LB) of the interconnecting, polygonal links
may be independently in the range of 2 mm to 30 mm, preferably in the range of 10
mm to 14 mm, and the thickness (LT) of the interconnecting, polygonal links is in
the range of 1 mm to 25 mm, preferably in the range of 10 mm to 14 mm.
[0081] Further, the weight (MW) of the sheet 102 may be varied. In particular, the weight
of the sheet 102 may be varied by employing heavy or light interconnecting, polygonal
links 104 and polygonal end cap links 106. In an embodiment, a mix of heavy and light
interconnecting, polygonal links 104 may be employed. In another embodiment, all the
interconnecting, polygonal links may have the same weight. In yet another embodiment,
the weight of the interconnecting, polygonal links and that of the polygonal end cap
links may be the same or different. In an embodiment, the weight (LW) of the interconnecting,
polygonal links 104 may be in the range of 0.1 grams to 25 grams. In another embodiment,
the weight (LW) of the interconnecting, polygonal links 104 may be in the range of
0.1 grams to 2 grams. In one embodiment, the weight (LW) of the interconnecting, polygonal
links 104 may be within the range of 0.18 grams and 0.17 grams.
[0082] In accordance with an embodiment, the weight (MW) of the sheet 102 may be in the
range of 10 grams to 1,000 grams. In another embodiment, the weight (MW) of the sheet
102 may be in the range of 50 grams to 100 grams. In one embodiment, the weight (MW)
of the sheet may be within the range of 55 grams and 60 grams.
[0083] In accordance with an embodiment of the present invention, the interconnecting, polygonal
links 104 may have a square shape as depicted in FIG. 2A, FIG. 2B and FIG. 2C. The
interconnecting, polygonal links 104 may comprise at least two lower horizontal connector
members (1042, 1044), which define an operative lower surface 104B of the interconnecting,
polygonal links 104, and at least two upper horizontal connector members (1046, 1048),
which define an operative upper surface 104A of the interconnecting, polygonal links
104. Further, the at least two lower horizontal connector members (1042, 1044) are
connected to the at least two upper horizontal connector members (1046, 1048) at corner
posts (1050) to define a continuous link.
[0084] In accordance with another embodiment of the present invention, the interconnecting,
polygonal links 104 may have a square shape as depicted FIG. 4A and FIG. 4B, wherein,
the interconnecting, polygonal links 104 comprises at least two lower horizontal connector
members (1042, 1044), which define an operative lower surface 104B of the interconnecting,
polygonal links 104, and at least two upper horizontal connector members (1046, 1048),
which define an operative upper surface 104A of the interconnecting, polygonal links
104. Further, the at least two lower horizontal connector members (1042, 1044) are
connected to the at least two upper horizontal connector members (1046, 1048) at corner
posts (1050) to define an incessant link, and a lower transverse intermediate connector
member 1052 is disposed between and connected to the at least two lower horizontal
connector members (1042, 1044) and an upper transverse intermediate connector member
1054 is disposed between and connected to the at least two upper horizontal connector
members (1046, 1048). The various corners and edges in the illustrated embodiment
are shown as forming 90 degree angles, however, in an embodiment the corners and edges
may comprise a fillet or chamfer to improve the overall smoothness of the swatch.
[0085] The provision of the lower transverse intermediate connector member 1052 and the
upper transverse intermediate connector member 1054 may further increase the surface
area and also the smoothness of the operative upper surface 104A and the operative
lower surface 104B of the interconnecting, polygonal links 104 and that of the sheet
102 and at the same time may provide strength to the interconnecting, polygonal links
104.
[0086] The swatch may include a macro-smoothness which refers to the texture of the swatch
as it feels to the user while the swatch is moved over the skin of the user and a
micro smoothness which refers to the smooth texture of the touchable surface of the
individual links which are free of sharp protrusions or corners. For example, the
touchable surface of the links although not mirror smooth may not have protrusions
from the bulk of the link of greater than 0.1 mm, with any another dimension within
75 degrees of surface of the link of less than 0.1mm. The macro-smoothness, in addition
to the smoothness of the touchable surface of the links, depends on the shape of the
links, their number per area and also on the gaps between the links.
[0087] In accordance with the present invention, the interconnecting, polygonal links 104
(FIG. 2A, FIG. 2B, FIG. 2C, FIG. 4A, and FIG. 4B) may have the operative upper surface
104A, the operative lower surface 104B, and one or more substantially smooth edges
104C, The operative upper surface 104A, the operative lower surface 104B and the one
or more substantially smooth edges 104C may have a shape which may be selected from
the group consisting of flat or planar, concave, convex, and any combinations thereof.
Any other shape is also well within the ambit of the present invention provided the
shape provides a smooth feel. In an embodiment, the operative upper surface 104A and
the operative lower surface 104B of the interconnection polygonal links each have
a flat surface.
[0088] In accordance with an embodiment of the present invention, at least one layer of
polygonal end cap link 106 is connected to an outer most layer 104D of the interconnecting,
polygonal links 104 of the sheet 102. In an embodiment, the polygonal end cap links
106 may be the same as that of the interconnecting, polygonal links 104. In another
embodiment, the polygonal end cap links 106 are different from that of the interconnecting,
polygonal links 104. In yet another embodiment, at least some of the polygonal end
cap links 106 may be the same as that of the interconnecting, polygonal links 104
and some of the polygonal end cap links 106 are different from that of the interconnecting,
polygonal links 104 in a given sheet 102. In the present context, the meaning of different
or same polygonal end cap links 106 is that the structure or design or form of the
polygonal end cap links 106 is same as that of the interconnecting, polygonal links
104 or the structure or design or form is different as compared to that of the interconnecting,
polygonal links 104. Any other shape of the polygonal end cap links 106 may include
a ring or a continuous loop-like structure. In the present context, the meaning of
different or same polygonal end cap links 106 may also mean that the composition of
the interconnecting, polygonal links 104 or the material of make of the interconnecting,
polygonal links 104 may be different or same.
[0089] In accordance with an embodiment of the present invention, the interconnecting, polygonal
links 104 may be in the form of polygons, wherein the polygon is at least one selected
from the group consisting of a three-sided polygon, a four-sided polygon, a five-sided
polygon, and a six-sided polygon. The shape of the interconnecting, polygonal links
104 may be at least one shape selected from the group consisting of a triangle, a
square, a rectangle, a hexagon and any combinations thereof. In an embodiment, the
sheet 102 may comprise a mix of links with some interconnecting, polygonal links 104
being four-sided polygons, and some others being six-sided polygons. In another embodiment,
the sheet 102 may comprise interconnecting, polygonal links 104 which are a mix of
three-sided and four-sided polygons. In an embodiment, the interconnecting, polygonal
links 104 may have a square shape when viewed from the top. In another embodiment,
the interconnecting, polygonal links 104 have a rectangular shape when viewed from
the top.
[0090] The interconnecting, polygonal links 104 and the polygonal end cap links 106 may
be each independently manufactured from a material selected from the group consisting
of plastic, elastomer, thermoplastic, metal, and any combinations thereof. The choice
of the material depends on the drape of the sheet 102 to be achieved, the body portion
over which the sheet 102 is to be used, and the weight of the sheet 102 to be achieved.
In an embodiment, the interconnecting, polygonal links 104 and the polygonal end cap
links 106 are each independently manufactured from plastic, preferably a thermoplastic
material such as a polyolefin thermoplastic including but not limited to homopolymer
polyolefins, random copolymer polyolefins and impact copolymer polyolefins. The plastic
material may be coloured or alternatively a paint coating may be employed. The plastic
material may be metal coated. The drape, the weight, the shape, and the structure
and design of the interconnecting, polygonal links 104 are selected so as to provide
a smooth feel when contacted with the body portion and provide stress relief when
played or engaged with the same. In an embodiment, the interconnecting, polygonal
links 104 and the polygonal end cap links 106 are each independently manufactured
from plastic. In an embodiment, the interconnecting, polygonal links 104 and the polygonal
end cap links 106 are each independently made of thermoplastic material.
[0091] In a specific embodiment, the chain mail mesh 100 may include a plurality interconnecting,
polygonal links 102 suitably interconnected to define a sheet 102 having a length
(ML), a breadth (MB), a thickness (MT), and weight (MW), each of the interconnecting
polygonal link 104 comprising at least two lower horizontal connector members (1042,
1044), at least two upper horizontal connector members (1046, 1048), at least one
lower transverse intermediate connector member 1052 disposed between and connected
to the at least two lower horizontal connector members (1042, 1044), and at least
one upper transverse intermediate connector member 1054 disposed between and connected
to the at least two upper horizontal connector members (1046, 1048), wherein the at
least two lower horizontal connector members (1042, 1044) along with the at least
one transverse intermediate connector member 1052 define an operative lower surface
1056 of the interconnection polygonal link 104, wherein the at least two upper horizontal
connector members (1046, 1048) along with the at least one transverse intermediate
connector member 1054 define an operative upper surface 1058 of the interconnection
polygonal link 104, wherein the at least two lower horizontal connector members (1042,
1044) being connected to the at least two upper horizontal connector members (1046,
1048) at corner posts 1050 to define an incessant link, wherein each of the interconnecting
polygonal link 104 is made of thermoplastic material and having a length and a breadth
in the range of 10 mm to 14 mm, independently, a substantially square shape, each
of the interconnecting, polygonal links being similar in structure, dimensions, and
shape, wherein each of the interconnecting polygonal link 104 is interconnected to
at least one neighbouring interconnecting polygonal link 104 combine to form an operative
upper surface 102A and an operative lower surface 102B of the sheet 102, wherein the
number of interconnecting, polygonal links 104 being in the range of 5 to 15 along
the length and the width of the sheet 102 independently, wherein the sheet 102 is
either having a substantially rectangular configuration or a substantially square
configuration wherein the sheet 102 is laid on a flat surface, wherein at least a
portion of at least one of the operative upper surface 102A and the operative lower
surface 102B of the sheet generally feels smooth, which produce a calming effect when
contacted with or moved over, or when contacted with and moved over a human's body
portion which being apt to sense of touch, and wherein the sheet 102 includes at least
one layer of polygonal end cap link 106 connected to an outer most layer of the interconnecting
polygonal link 104 of the sheet 102, the polygonal end cap link 106 being same as
that of the interconnecting polygonal link 104 or the polygonal end cap link 106 being
different from that of the interconnecting polygonal link 104.
[0092] In an embodiment, at least a portion of the sheet 102 is bendable in at least one
direction selected from an operative upward direction 102C of the operative upper
surface 102A of the sheet 102, an operative downward direction 102D of the operative
lower surface 102B of the sheet 102 and a combination thereof. In particular, the
sheet 102 has a predetermined drape coefficient similar to a cloth or a fabric, but
at the same time, the sheet 102 has a predetermined radius of curvature when the sheet
102 is placed on a support. This, in turn, means that the sheet 102 though bendable
in operative upper and lower directions, is not completely flexible as a cloth or
fabric. In an embodiment, the sheet 102 has a predetermined drape coefficient. In
accordance with an embodiment of the present invention, the drape coefficient of the
sheet 102 may be the same along the length (ML) and the breadth (MB) of the sheet
102. In another embodiment, the drape coefficient of the sheet 102 may be different
along the length (ML) and the breadth (MB) of the sheet 102. Further, the thickness
(MT) of the sheet 102, when the sheet is in draped configuration, is different from
the thickness (MT) of the sheet, when the sheet 102 is placed on a substantially flat
surface.
[0093] Owing to the above, the bendability and the radius of curvature of the sheet 102,
the sheet 102 drapes when contacted with or moved over, or when contacted with and
moved over a human's body portion and substantially conforms to the shape of the body
portion, wherein the operative lower surface 102B of the sheet 102 in contact with
the body portion provides a calming effect thereto.
[0094] In order to facilitate the draping of the sheet 102, the interconnecting, polygonal
links 104 within the sheet 102 are spaced apart with a gap 102E in an at rest state
therebetween, the gap 102E being in the range of 0.2 mm to 10 mm, more preferably
in the range of 0.5 mm to 4 mm, thereby configuring a loose hinge between two consecutive
interconnecting, polygonal links 104. A minimum, smaller gap of 0.1 mm, preferably
of 0.2 mm is envisioned to avoid pinching or catching of hair. The gap 102E provides
the necessary flexibility and hence bendability and the drape to the sheet 102. At
the same time, the shape of the interconnecting, polygonal links 104 along with the
dimensions and the gap 102E also make the sheet 102 resistant to drape further than
a predetermined curvature. It has been discovered by the Applicant that the sheet
102 having the above configuration when contacted with a body portion of a human provides
a calming effect thereto. Further, owing to the gaps, and the dimensions of the interconnecting,
polygonal links 104, at least a portion of the sheet 102 is skewable in at least one
direction substantially parallel to a plane of the sheet 102. In the preferred embodiment
the XY area of the gaps is smaller than the solid XY area of the link 104, when the
sheet is in a configuration having its smallest XY area.
[0095] In an embodiment, the dimensions, the shape, the material of make of the sheet 102
are chosen such that the sheet 102 when displaced is capable of generating an acoustic
spectrum during typical play or movement between the fingers or two human hands. In
an embodiment, the acoustic spectrum has at least one frequency in the range of 20
Hz to 20,000 Hz.
[0096] The chain mail mesh 100, the interconnecting, polygonal links 104 and the polygonal
end cap links 106 may be manufactured by any known method in the art. For example,
the chain mail mesh 100, the interconnecting, polygonal links 104 and the polygonal
end cap links 106 may be manufactured by at least one method selected from the group
consisting of 3D printing, injection molding (for example, continuous plastic injection
molding), snap fitting, casting, such as zinc casting, and any combinations thereof.
In an example, the interconnecting, polygonal links may be injection molded separately
and then snap-fitted to configure the sheet 102.
[0097] In accordance with another aspect, a method of reducing stress or otherwise improving
mental state in humans employing the chain mail mesh 100 hereinabove is disclosed.
The method comprises the steps of contacting with or moving over, or combinedly contacting
with and moving over a human's body portion which being apt to sense of touch, the
chain mail mesh 100, wherein the chain mail mesh 100 intermittently contacts with
nerve endings of the body portion thereby provide a calming effect thereto.
[0098] In accordance with yet another aspect, a process for reducing stress in humans is
disclosed, wherein the process comprises the steps of holding the chain mail mesh
100, in hands of a human, contacting the chain mail mesh 100 with a body portion of
the human and/or moving the chain mail mesh 100 over the body portion of the human
such that the operative lower surface 102B or the operative upper surface 102A contacts
with nerve endings of the body portion and thereby provide a calming effect thereto,
and repeating the above steps more than once to reduce the stress in humans.
[0099] In accordance with the present invention, the body portion with which the chain mail
mesh 100 is contacted may be at least one selected from the group consisting of hand,
wrist, head, forehead, face, shoulder, back, chest, neck, finger, calf, knee, thigh,
hip, waist, foot, heel, ankle, buttock, leg, skin, and stomach, and is not limited
to these. The preferred boy part comprises fingers and at least part of one or two
hands.
[0100] Though the present invention has been described with reference to contacting with
and/or moving over, the chain mail mesh, the body part of a human, there may be other
ways that may be employed to engage with the chain mail mesh. For example, the chain
mail mesh of the present invention may be simply draped over the hand(s), forearm,
leg, or foot. The chain mail mesh may be rattled to emit a noise/sound, which may
be stress relieving for some. Further, the chain mail mesh may be rubbed against skin
or wrapped on a finger or may be placed on a hard surface and rest a body part or
skin over it or may be played with by placing it in a pocket.
[0101] Further, the surfaces, the operative upper surface and the lower operative surface
of the interconnecting, polygonal links and that of the sheet 102 may be made somewhat
rough rather than being smooth as described hereinabove, which may be used for playing
with.
[0102] The present invention may also be used to better observe signs of stress and other
underlying feelings during psychological therapy sessions, interrogations, job interviews
and the like. Applicant has observed that subjects holding the present invention tend
to play with it more frequently and with more intensity during more stressful moments.
The visual and audible indicators are often somewhat proportional to stress, anxiety
or similar feelings, especially when correlated with the same subject.
[0103] The present invention is now described with reference to the following examples which
are provided to illustrate the present invention more clearly and not to limit the
scope thereof.

wherein each of said interconnecting polygonal link is made of thermoplastic material
and having a length and a breadth in the range of 10 mm to 14 mm, independently,
wherein each of said interconnecting polygonal links being similar in structure, dimensions,
and shape,
wherein each of said interconnecting links is interconnected to at least one neighbouring
interconnecting polygonal links combine to form an operative upper surface and an
operative lower surface of said sheet,
wherein the number of interconnecting links being in the range of 5 to 15 along the
length and the width of said sheet independently,
wherein said sheet is either having a substantially rectangular configuration or a
substantially square configuration wherein said sheet is laid on a flat surface,
wherein at least a portion of at least one of said operative upper surface and said
operative lower surface of said sheet generally feels smooth, which produce a calming
effect when contacted with or moved over, or when contacted with and moved over a
human's body portion which being apt to sense of touch, and
wherein said sheet includes at least one layer of polygonal end cap links connected
to an outer most layer of said interconnecting polygonal links of said sheet, said
polygonal end cap links being same as that of said interconnecting polygonal links
or said polygonal end cap links being different from that of the interconnecting polygonal
links.
14. A method of using the device of claim 1, the method comprising:
placing the device on a body portion of a human which is apt to sense of touch, and
