TECHNICAL FIELD
[0001] The present invention relates to the field of weight lifting and, in particular,
to grip assist apparatus for use therein.
BACKGROUND ART
[0002] Strength training has become a widely practiced activity for both men and women.
In addition to being a sport in and of itself, strength training is also utilized
as a conditioning and strengthening exercise for other sports, such as football, basketball,
and baseball. Furthermore, athletes who rely on agility, such as tennis players, also
benefit from strength training.
[0003] In sports, protective equipment is utilized to prevent injury to the participant.
With respect to strength training, protective equipment is also needed, as all the
joints of the body may be subjected to extreme forces. In particular, the wrist joint
is subjected to these extreme forces any time the trainee's hands utilize a weight
bar during the course of strength training.
[0004] It is also important to protect the palm during weight lifting. This is particularly
true during weight lifting exercises when the weight lifter is pushing the weights
away from his body, such as with the bench press. FIG. 1 is a skeletal depiction of
the hand. The cross hashed bones form the metacarpus consisting of the first 608,
second 606, third 604, fourth 602, and fifth 600 metacarpals. The shaded portion near
the wrist is the carpus 614. Lines 612, 610 show the rough dimensions of the deep
and superficial palmar arches, respectively. The palm of the hand is formed skeletally
by the metacarpus consisting of metacarpal bones 600-608. The metacarpus is the intermediate
part of the hand skeleton located between phalanges, or bones of the fingers, and
the carpus 614 which forms the connection to the forearm. The metacarpals form a transverse
arch to which the rigid row of distal carpal bones are fixed. The peripheral metacarpals
- those of the thumb 608 and little finger 600 - form the sides of the cup of the
palmar gutter as they are brought together, they deepen this concavity. The shape
of the palm over these bones is formed primarily by the radial and ulnar arteries
forming the deep 612 and superficial 610 palmar arches. The superficial palmar arch
610 reaches its apex at about the middle of the metacarpus, while the deep palmar
arch 612 reaches its apex about one quarter of the way between the carpus 614 and
phalanges, over the metacarpus. The ulnar nerve in particular, as well as the radial
and median nerves, are affected by pressure to the palm. Exercises that put a large
amount of pressure on these nerves leave the weight lifter susceptible to injury and
syndromes, such as carpal tunnel syndrome and Guy on's canal syndrome.
[0005] Now referring to FIG. 2, a diagram of a human hand is provided. Overlaid are indications
of approximate positions of the thumb fat pad 200, pinky fat pad 202, and metacarpal
fat pad series 204. These fat pads are subcutaneous fatty deposits that effectively
frame the palm. Thumb fat pad 200 is positioned below the thumb and extends down almost
to the wrist. The term"thumb fat pad" as used herein is understood to be so positioned,
as illustrated. Metacarpal fat pad series 204 are a series of smaller fat pads roughly
covering the tops of metacarpals 600, 602, 604, 606 (as shown in FIG. 1) that together
extend across the top of the palm below the fingers. The term"metacarpal fat pad series"
as used herein is understood to be so positioned, as illustrated. Pinky fat pad 202
is positioned below the metacarpal fat pad series 204 and the pinky or little finger
and, like the thumb fat pad 200, extends down almost to the wrist. The term"pinky
fat pad" as used herein is understood to be so positioned, as illustrated. These pads
200, 202, 204 surround dotted area of vulnerability 206. Area of vulnerability 206
does not include fatty deposits, such as pads 200, 202, 204, and is therefore relatively
unprotected compared to the rest of the palm. Comparing FIGS. 1 and 2, this area of
vulnerability 206 corresponds approximately with the area defined within the lines
610, 612 corresponding to the superficial and deep palmar arches. The term"area of
vulnerability" as used herein is understood to be so positioned between pads 200,
202, 204, and roughly corresponding to the area defined within lines 610, 612, as
illustrated. It is this relatively unprotected portion of the palm that is most vulnerable
to injury during weight lifting, particularly pushing exercises.
[0006] U.S. Patent No. 5,813,950 issued to the present inventor describes a novel development in grip assist apparatuses
in which the flexible gripping portion that covers the palm of the lifter is formed
of a tacky non-slip material that is sewn in such a way that the lifter has free movement
of his hands when he is not gripping the weight bar. The grip assist comprises a gripping
portion that extends from the lifter's wrist to the fingertips and covers the base
of the hand and is connected to a wrist strap that is of a funnel-shaped design that
provides wrist support. A feature and advantage of the grip assist apparatus invention
described in
U.S. Patent No. 5,813,950 is that the gripping strap must be able to free stand up in front of the hand in
order to be easily wrapped around the lifting bar with the tips of the fingers on
the same hand. The gripping portion in the above-mentioned invention can be used for
both pushing and pulling exercises and protects the palm of the hand from friction.
The present inventor has discovered that the grip assist apparatus described in
U.S. Patent No. 5,813,950 has valuable application in the medical field for orthopedic rehabilitation and health-related
applications. In these applications, further protection for any pushing motions is
desired.
[0007] U.S. Patent No. 5,771,901 discloses an arch support for a hand that is a plate made to conform to the palm
of the hand and has support edges. Although capable of supporting the palm, the invention
of this patent does not protect any other part of the hand or wrist that may be affected
during strength training, nor does it provide any grip assistance as is preferable
during strength training. Moreover, it is hand specific, so one must be purchased
for each hand.
[0008] U.S. Patent No. 4,374,439 discloses a bowler's wrist support that includes a flexible body adapted to be wrapped
around the hand and wrist straps to hold it in position and a pocket within which
fits a pad which is positioned at the palm of the hand. The pad is to fill the space
between the palm of the hand and the surface of the ball to provide better contact
with the ball to lead to better control. The pad is of foam plastic material which
possesses some resilience. The pad is shaped so as to have two relatively straight
edges meeting at a rounded comer where the pad is the thickest. This part of the pad
fits at the base of the heel of the hand. An arcuate edge of the pad, where it has
tapered to its minimum dimension, extends from the end of one of the straight edges
and is positioned just below the base of the fingers on the palm of the hand when
the wrist support is in use. From the other end of the arcuate edge is a short straight
edge that is adjacent the side of the hand, which connects to another straight edge
which extends near the base of the thumb. Although capable of aiding in bowling, this
invention is ill-suited to provide palm support for weightlifting purposes. Specifically,
the pad's flexible nature will adjust with changes in pressure, making changes in
grip on a bar difficult. Moreover, as it is contoured to the palm, it is hand specific.
In bowling, where most bowlers use only one hand, this is not a problem, but in weightlifting,
this would require that the user again determine which grip is used on which hand
and prevents a pair from being used by two people.
[0009] U.S Patent no. 8,065,749 discloses a protective sheet for the hands with a hypoallergenic adhesive. The rectangular
sheet is folded in half with cutouts for the fingers to slide through. The sides of
the invention are open for un-obstructive movement of the thumb. The invention includes
a cutout at the base of the hand to prevent any creasing of the material when the
hand is curved in a gripping formation. In addition, the invention can be worn under
a glove and can be used in any activity that may cause surface blemishes to the palmar
part of the palm. Although the hypoallergenic sheet protects the hand and more particularly
the palmar part of the hand from skin lesions caused by friction, the invention does
not protect the vulnerable part of the hand from internal injuries or from carpal
tunnel syndrome.
[0010] U.S. Patent No. 6,154,882 discloses a protection device intended for reducing the risk and effect of hand and
arm injuries during heavy impact. The device is composed of two elements, the knuckle
protector and a gripping element. The gripping element is located in the palmar part
of the hand and the invention supports several designs. All of the designs of the
U.S. Patent No. 6,154,882 gripping portion contain materials that utilize layers for bendable, slide-able movement
when falling. All of the designs encourage the hand to grip around the gripping portion
upon impact. All of the gripping portion designs follow the same understanding that
if your hand is in a gripping position during falls i.e. a ski accident, the risk
of injuries to the forearm, the wrist, the small bones of the hand or the fingers
is reduced substantially. While the invention protects the user from heavy impacts
caused by falling, the invention does not prevent injuries for pushing movements and
assist with orthopedic therapy for building strength.
[0011] U.S. Patent No. 4,546,495 discloses a weightlifting glove apparatus that includes a tapered wedge extending
from the heel of the hand inwardly toward the inside palm for use in weightlifting
when presses are used. The wedge of this invention is somewhat flexible so that it
will curve or bend with the hand as the hand grasps the bar. The wedge includes a
generally flat base which extends from the heel of the hand upwardly toward the palm.
Extending between opposite ends of the base there is a rounded edge which defines
the outer periphery of the wedge. The top or upper portion of the wedge is a generally
smoothly continuous concave area. There is a smoothly continuous tapering convex bohom
to the wedge which extends from the base outwardly toward a distal end. The distal
end is remote from the base. The thickness of the wedge varies from a maximum at the
base to a minimum at the distal end. The concave top and the convex bohom are somewhat
parallel to each other, although there is a tapering toward each other from the base
to the distal end, and both the concave top and the convex bohom taper towards the
distal end. Although the wedge of this patent is directed toward weightlifting, it
still has drawbacks. Specifically, its flexible nature will adjust with changes in
pressure, making changes in grip on a bar difficult. Moreover, as it covers a relatively
large area of the hand, and is contoured to the hand, it is hand specific, so one
must be purchased for each hand.
[0012] There is prior art for devices of the hand that may be worn on either hand.
U.S. Patent No. 6,102,880, for example, discloses a lightweight wrist brace that has a flexible base which
extends along the palm and receives a stiffening member within a pocket and is capable
of being worn on either a right or a left hand. Although useful for some purposes,
this wrist brace would be ill-suited for use in weightlifting. Specifically, it is
designed to restrain the movement of the wrist, and the ability to use a full range
of wrist motion during weight lifting is preferable. Moreover, it protects only a
very small portion of the hand, leaving many areas of the hand that may be affected
by weight lifting exposed. Also, as it includes two hand straps that wrap around the
hand and are connected to each other across the dorsal area of the hand, it may unduly
restrict a gripping motion of the hand, whereas an unfettered grip is extremely important
in weightlifting.
[0013] U.S. Patent 5,620,399 discloses a gripping sleeve for tightly gripping an object by hand. The gripping
sleeve is formed of a plate formed of a tightly gripping or clinging material, the
plate being connected to a wrist band by a connecting web. The gripping sleeve can
be put on a user's wrist with the wrist band, so that the plate lies in the palm of
his or her hand. The plate is, preferably, in the shape of a circle. Although capable
of providing grip assistance and to be worn on either hand, this invention has its
disadvantages. It provides no additional palm support beyond the plate itself. Only
the narrow web covers the base of the hand, leaving much of the base of the hand exposed
and prone to irritation and/or injury.
[0014] U.S. Patent 5,581,809 to Mah (hereinafter"Mah") discloses a protective glove having a back portion, a palmar
portion, and a plurality of digital sheaths distally projecting from between the back
and palmar portions for use on the hand of a wearer. The protective glove provides
a plurality of flexible resilient pads for absorbing shock positioned on the palmar
portion of the glove in spaced, non-overlapping relation to each other and in adjacent
substantially non-overlapping relation to the proximal digital crease, the distal
transverse palmar crease and the longitudinal thenar crease, such that the plurality
of flexible resilient pads abut one another in edge-contacting relation upon flexion
of the hand to form a substantially continuous, non-creased shock absorbing layer
covering the metacarpal region of the hand. The gloves are therefore designed to absorb
shock on the palm, not to avoid pressure on certain parts of the palm altogether.
The gloves also specifically teach that the resilient pads should not cross over any
of the palmar creases, but that they are specifically positioned around the various
palmar creases so that when the hand is in flexion, the pads will fold into the palmar
creases.
[0015] According to Mah, col. 6, lines 43-45,"resilient pads 34, 46, 48, 50, and 52 are
retained between the palmar portion 24 and the lining 64." As such, wherever one of
Mah's pads is disposed, there are three layers - the pad itself, the palmar portion,
and the lining. Several of these pads are disposed over the area of vulnerability
206, as shown in FIG. 2. Mah's pads substantially cover its palmar portion, and the
palmar portion includes at least three layers where the pads are disposed.
[0016] Mah's carpal pad 34 is an insert that is, at least softly, U-shaped. The tops of
this gently U-shaped carpal pad are not disposed anywhere near the metacarpal fat
pad series 204. Mah teaches away from modifying its carpal pad 34 so that its tops
would reach upward to be disposed on top of the metacarpal fat pad series. Mah stresses
that,"[t]he improvement of the present invention... lies in the positioning and composition
of a plurality of flexible means... positioned in spaced relation adjacent to, but
substantially not overlapping, the major creases of the hand." [Emphasis added, Mah,
col. 4, lines 9- 19] Mah goes on to explain that the various pads are specifically
positioned around the various palmar creases so that when the hand is in flexion,
the pads will fold into the palmar creases. [Mah, col. 4, line 47-col. 5, line 20]
For Mah's carpal pad 34 to extend far enough up the palm so that tops of its gently
U-shapes carpal pad were disposed on top of the metacarpal fat pad series, the carpal
pad would have to overlap several creases of the hand, which Mah teaches not to do.
[0017] It is notable that if Mah's crescent shaped resilient carpal pad 34 were disposed
higher in the glove so that the tops of the gently U-shaped insert were disposed on
top of the metacarpal fat pad, then, in order to conform to Mah's edict that the pads
not overlap the palm creases, the connecting portion of the pad would not be disposed
proximate to the wrist end. The preceding discussion is valid no matter the size of
the user's hand. Every hand has palmar creases between the metacarpal fat pad series
and the wrist area and Mah will always require that those palmar creases not be overlapped.
[0018] Mah's palmar portion has no edges because Mah discloses a glove. There is no structural
cut off or edge to Mah's palmar portion because it extends around the palm and up
and between the fingers. In addition, as Mah's glove wraps all the way around the
user's hand, it cannot include contouring on the edges on either side of the palmar
portion because Mah's glove has no such edges. Therefore there is a need for a grip
assistance apparatus that may be worn on either hand; that includes a palm protection;
that adequately protects the parts of the hand that are affected during weightlifting;
and that does not unduly restrict the hand's gripping motion.
SUMMARY OF THE INVENTION
[0020] According to an aspect of the present invention, there is provided a grip assist
apparatus for weightlifting as claimed in claim 1.
[0021] The present invention is a grip assist apparatus with a built in arch support insert
that will protect the hand's area of vulnerability for any pushing movements promoted
in the orthopedic rehabilitation field. The preferred grip assist apparatus of the
present invention includes gripping portion that extends from a wrist portion, and
a releasable wrist fastener. The inventor's related inventions disclosed in
U.S. Patent no. 8,581,950 and U.S. Patent Publication No.
US 20110214220 (
US Patent Application no. 12/660,856). One of at least ordinary skill in the art will recognize that some aspects or details
discussed in each of these disclosures, but not discussed herein, may be applicable
to the present invention.
[0022] In one embodiment, the grip assist apparatus includes a gripping portion, which covers
at least the palm of hand when worn as intended, and a wrist portion attached to the
gripping portion. The wrist portion includes straps and fastening means for fastening
the wrist portion around the user's wrist, thereby allowing the gripping portion attached
thereto to be held against the user's hand. The gripping portion is made of at least
two halves or layers. The gripping portion of the preferred grip assist apparatus
is preferably made of a single flat piece of material that is folded along a first
line of symmetry. It is understood, however, that the gripping portion may be made
of two separate pieces of material that are affixed to one another so as to be flush
with one another except where one or more inserts may be included between the two
halves. The gripping portion of the preferred grip assist apparatus has a finger end
at the top, a wrist end opposite from the finger end, attachment edges near the wrist
end, for attaching the straps of the wrist portion, and first and second sides between
the finger end and the attachment edges.
[0023] The gripping portion also includes an insert, which is an arch support structure,
inserted between the two halves, where the insert includes a gap. The insert, when
placed between the two halves, causes that gripping portion to have three layers everywhere
except the gap, where the gripping portion will still have only two layers. The gap
is positioned within the insert so that it will cover the area of vulnerability of
a user's hand when the user wears the grip assist apparatus. The insert may be of
any shape as long as the gap is in a position so that it will be over at least a portion
of the area of vulnerability of the user's hand and the insert is disposed over at
least a portion of the thumb fat pad, the pinky fat pad, and the metacarpal fat pad
series of the user's hand when the grip assist apparatus is worn when the grip assist
apparatus is worn. This shape may be, for example, a donut shape, either rounded or
rectangular as long as the gap in the middle is properly positioned as described above.
The insert may also be two inserts in the form of parallel strips with the gap therebetween,
the strips being either above and below the area of vulnerability or on either side
of the area of vulnerability when the grip assist apparatus is worn.
[0024] The insert disposed between the two halves is U- shaped. The U-shaped insert covers
at least a portion of the thumb fat pad, the pinky fat pad, and the metacarpal fat
pad series. The gap between the two sides of the U-shaped insert covers the area of
vulnerability proximate to the metacarpal fat pad series and extending from the metacarpal
fat pad series toward the pinky fat pad and the thumb fat pad when said grip assist
apparatus is worn over the palmer portion of the hand as intended. The added support
of the U-shaped insert will take on additional pressure during any pushing movements
so that the area of vulnerability will not come into contact with the bar that is
being pushed, thus preventing stress and injury on the area of vulnerability and promotes
unrestricted circulation.
[0025] The U-shaped insert has a first U side near the first side of the gripping portion,
a second U side near the second side of the gripping portion, and a connection portion
that connects the first and second U sides and is near the wrist end of the gripping
portion. Where the U-shaped insert is disposed, the gripping portion has at least
three layers - the U-shaped insert and the two halves. Between the first and second
U sides is a gap where the gripping portion is only two layers, namely the two halves.
The U-shaped insert is positioned within the gripping portion so that when the grip
assist apparatus is worn, the U-shaped insert covers at least a portion of the thumb
fat pad, the pinky fat pad, and the metacarpal fat pad series. The gap covers the
area of vulnerability. The added support of the U-shaped insert will take on additional
pressure during lifting so that the area of vulnerability will not come into contact
with the lifting bar, thus preventing stress and injury on the area of vulnerability.
The U-Shaped insert builds up and supports the pinky fat pad, the thumb fat pad, and
the metacarpal fat pad series so that the pressure on the palm of the hand does not
come in contact with the area of vulnerability. The grip assist apparatus with built
in arch support insert for is suitable for therapeutic rehab. It is preferred that
the gripping portion be made of non-slip material and an end piece be included at
the finger end of the gripping portion between the two halves of material. The first
and second attachment edges of the gripping portion of the present invention are angled
so that when the first and second straps for the wrist portion are secured about the
user's wrist via the wrist fastener, the first and second straps and the gripping
portion form a funnel-shaped enclosure around the wrist and base of the hand, where
the enclosure has an opening that is larger at its distal end that at is proximal
end. The first and second straps of the wrist portion are substantially rectangular,
"substantially" meaning here that the comers may be rounded, rather than perfect right
angles. It is preferred that the means for fastening the straps of the present invention
grip assist apparatus around the wrist include a ring on the end of the first strap
and sections of hook and loop-type fastener on the second strap, so that the second
strap may be threaded through the hook of the first strap and then fastened to itself
by way of its hook and loop- type fastener sections. The gripping portion of the grip
assist apparatus has rigidity such that it is self-supporting and will remain extended
in front of the user's palm and fingers to allow it to be manipulated by the very
hand on which it is worn. The gripping portion of the grip assist apparatus is sufficiently
flexible to allow itself to be easily wrapped around a bar and the two halves forming
the gripping section of the grip assist apparatus be secured by stitching them together.
[0026] The U-shaped built in arch support structure insert for the grip assist apparatus
will protect the vulnerable area of the user's palm in any pushing motion thereby
protecting the user from injury and carpal tunnel syndrome and will be useful in orthopedic
therapy where a user must build the muscles in his upper body while taking care to
not have any further injuries. There have been several studies by doctors and they
agree that this built in arch support insert has positive results for patients recovering
from wrist and hand injuries. The U-shaped built in arch support is made of a firm
flexible material that protects the vulnerable area of the palm by building up the
pinky fat pad, the thumb fat pad, and the metacarpal fat pads. In addition, the built
in arch support promotes circulation by preventing pressure to the median nerve.
[0027] In a preferred embodiment, the grip assist apparatus is symmetrical, and therefore
wearable on either hand. In this preferred embodiment, each of the halves or layers,
which are affixed flush against one another, has a second line of symmetry. It is
this second line of symmetry that allows the grip assist apparatus to be wearable
on either hand. The first and second sides include mirror image contouring to allow
for thumb movability on either side.
[0028] It is preferred that the gripping portion be made of non-slip material. It is preferred
that an end piece be included at the finger end of the gripping portion of the preferred
grip assist apparatus between the two halves of material. It is preferred that the
first and second attachment edges of the gripping portion of the preferred grip assist
apparatus are angled so that when the first and second straps of the wrist portion
are secured about user's wrist via the wrist fastener, the first and second straps
and the gripping portion form a funnel-shaped enclosure around the wrist and base
of the hand, where the enclosure has an opening that is larger at its distal end than
at its proximal end. It is preferred that the first and second straps of the wrist
portion be substantially rectangular, "substantially" meaning here that the comers
may be rounded, rather than perfect right angles. It is preferred that the means for
fastening the straps of the preferred grip assist apparatus around the wrist include
a ring on the end of the first strap and sections of hook and loop- type fastener
on the second strap, so that the second strap may be threaded through the hook of
the first strap and then fastened to itself by way of its hook and loop-type fastener
sections. It is preferred that the gripping portion of the preferred grip assist apparatus
have rigidity such that it is self-supporting and will remain extended in front of
the user's palm and fingers to allow it to be manipulated by the very hand on which
it is worn. Moreover, it is preferred that the gripping portion of the preferred grip
assist apparatus be sufficiently flexible to allow itself to be easily wrapped around
a lifting bar using only the tip of a finger of the hand on which it is being worn.
It is preferred that the two halves of material forming the gripping section of the
preferred grip assist apparatus be secured by stitching them together. It is also
preferred that the stitching help to hold the U-shaped insert in place and define
the gap.
[0029] In an alternative arrangement, the gripping portion is integrated into a weightlifting
glove. In such arrangements, the wrist portion is eliminated and is replaced by a
glove made of a flexible material that is shaped and dimensioned to cover the user's
palm and at least a portion of each finger. The gripping portion covers at least the
palm of hand when worn as intended and includes two layers of material and an insert
disposed these layers.
[0030] In some such embodiments, the glove material covering the user's palm forms the first
layer of the gripping portion, the insert is positioned upon this layer such that
it covers at least a portion of the thumb fat pad, the pinky fat pad, and the metacarpal
fat pad series, and is secured to the glove material by a separate layer of material
that forms the outer layer of the gripping portion when the grip assist apparatus
is worn. However, in other embodiments, the gripping portion includes two separate
layers that are secured together with the insert in the desired position therebetween
and this gripping portion is secured to the glove material covering the user's palm.
[0031] Apparatuses for grip assists are designed to strengthen the lifter's grip by providing
support to the wrist and hand. The flexible gripping portion covers and protects the
palm of the hand. The gripping portion is often made of one piece of symmetrical material
that is folded in half. A wrist strap is connected to the base of the gripping material
and provides wrist support. The gripping portion of the preferred grip assist apparatus
also includes an arch support structure inserted between the two halves of the gripping
material. It is preferred that the built in arch support insert disposed between the
two halves of the gripping portion be U-shaped. The built in arch support insert provides
additional protection to the vulnerable area of the user's palm. The built in arch
support insert will take on additional pressure during any pushing movements so that
the weight is evenly distributed and the area of vulnerability of the user's palm
will not come into contact with the bar that is being pushed, thus preventing stress
and injury on the area of vulnerability. The U-shaped arch support insert may be designed
for therapeutic applications in physical therapy generally.
[0032] The arch support insert is used in a grip assist apparatus, and protects the user
from injury or developing carpal tunnel syndrome. The invention is applicable, for
example, in pushing movements promoted in orthopedic rehabilitation. Any pushing movement
that involves direct compression upon the area of vulnerability of the palm can contribute
to the development of carpal tunnel syndrome. Prolonged pressure will result in compression
of the median nerve and a reduction of blood flow.
[0033] The U-shaped arch support insert of the preferred grip assist apparatus is designed
by building up the density of the flexor and abductors muscles found just below the
thumb and pinky fingers. By building up the sides of the hand the U-shaped insert
acts as an arch support and helps to prevent direct pressure on the area of vulnerability
of the palm and thereby, leads to unrestricted blood circulation and protection of
the median nerve.
[0034] For orthopedic rehabilitation pushing movements will often include a weighted bar
to build strength in the user's upper body. The U-shaped insert of the preferred grip
assist apparatus balances and distributes the weight evenly across the hand and creates
a unique arch support that allows the user to keep the hand in a natural open-hand
extended position versus the traditional clenched fist. The open-hand, non-gripping,
position allows the weighted bar to rest lower on the hand and closer to the wrist.
This position of the hand improves the power transfer by putting the weight bar over
the forearm bones making the weight easier to push. The unique design of the U-shaped
arch-support builds up the sides of the user's palm to create space and deflect the
pressure of the weight bar away from the area of vulnerability to protect the median
nerve. The built in arch support of the U- shaped arch support insert becomes a "Bridge
like structure" that carries the weight bar over the fragile carpal tunnel area while
protecting the median nerve and allowing for unrestricted blood circulation to the
hand.
[0035] The preferred glove is a weightlifting glove of a half finger design and is made,
at least in part, from a breathable material. However, in some embodiments, the glove
is of a full finger design that is adapted for work or cold weather use.
[0036] It is therefore an object of the present invention to provide grip assist apparatuses
with an arch support structure to prevent injury which protects the area of vulnerability
of the user's palm and guards against carpal tunnel syndrome.
[0037] A further object of the invention is to provide additional protection of the metacarpal
area of the user's palm when performing any pushing movements.
[0038] Yet another object of the invention is to provide protection of the ulnar, radial,
and median nerves and thereby promote circulation from the user's wrist to his fingertips
when performing any pushing movements.
[0039] These aspects of the present invention are not meant to be exclusive and other features,
aspects, and advantages of the present invention will be readily apparent to those
of ordinary skill in the art when read in conjunction with the following description

BEST MODES FOR CARRYING OUT THE INVENTION
[0041] Referring first to FIG. 3 A, the grip assist apparatus 10 of the present invention,
which embodies what the inventor believes to be the best mode of carrying out the
invention, is depicted. The grip assist apparatus 10 includes gripping portion 12,
wrist portion 28, and wrist fastener 36.
[0042] Gripping portion 12 is dimensioned to cover a human hand from the fingers to below
the wrist joint, without impeding the thumb's movement. Although flexible enough to
be easily wrapped around a lifting bar with only the fingers of the hand on which
the grip assist apparatus 10 is worn, gripping portion 12 preferably has a rigidity
so that it is self-supporting and will remain extended in front of the palm and fingers
if not manipulated by the hand on which grip assist apparatus 10 is worn.
[0043] In the embodiment of FIG. 3 A, gripping portion 12 includes finger end 18, wrist
end 70, first attachment edge 72, second attachment edge 74, first side 76, and second
side 78. Finger end 18, first side 76, and second side 78 are also labeled as first,
second, and third gripping portion edges 706, 708, 710 indicating that these are edges
of gripping portion 12, i.e. that gripping portion 12 does not extend further than
these edges 706, 708, 710 and is not connected to other structures at these edges
706, 708, 710. It is noteworthy that any sort of glove would not include such edges
because the glove, by its nature, will wrap all the way around a hand. Finger end
18 and wrist end 70 are opposite from one another at the top and bottom of gripping
portion 12, respectively. Wrist end 70 has first wrist end flank 500 on its side toward
first strap 30 and second wrist end flank 502 on its other side toward second strap
31. It is understood that first and second wrist end flanks 500, 502 denote either
side of wrist end 70. "Flank" is being used in this context as a synonym for "side,"
but the inventor, acting as his own lexicographer, has chosen to use "flank" here
so as to avoid confusion with the word "side" used in other contexts herein. First
and second attachment edges 72, 74 are disposed adjacent to first and second wrist
end flanks 500, 502 of wrist end 70. First and second sides 76, 78 extend between
finger end 18 and first and second attachment edges 72, 74. First and second sides
76, 78 each include contouring 16, which accommodate the user's thumb. Concave contouring
16 results in a narrowing 702 in first and second sides 76, 78; a first widening 700
between narrowing 702 and finger end 18; and a second widening 704 between narrowing
702 and wrist end 70. As will be discussed in more detail below, first and second
attachment edges 72, 74 are where first and second straps 30, 31 extend from gripping
portion 12.
[0044] In embodiments that may be worn on either hand, gripping portion 12 includes second
line of symmetry 14. Second line of symmetry 14 is not a structure that would be readily
apparent by looking at the gripping portion 12 but, rather, is an imaginary line that
runs the length of gripping portion 12. The symmetry of the gripping portion 12 allows
the preferred grip assist apparatus 10 to be worn on either hand. Although it is understood
that there are at least two symmetries along second line of symmetry 14, including
symmetry through the plane of gripping portion 12, it is understood that as used herein,
"second line of symmetry" refers only to the symmetry that becomes apparent if one
were to fold the gripping portion 12 along the second line of symmetry 14. It is further
understood that although "first" features of gripping portion 12 are indicated on
the right and "second" features" of gripping portion 12 are indicated on the left,
these designations are arbitrary, as gripping portion 12 is symmetrical and all "first"
and "second" features of gripping portion 12 are mirror images of the other across
second line of symmetry 14.
[0045] Gripping portion 12 includes U-shaped insert 80, which is detailed in FIG. 3B. Although
U-shaped insert 80 is the preferred shaped insert of the present invention, it is
understood that any insert that includes a gap 104 that will be disposed on top of
at least a portion of the area of vulnerability of a wearer of the grip assist apparatus
10 is sufficient for the present invention. U-shaped insert 80 is disposed between
halves 71, 73 (shown most clearly in FIG. 4) of gripping portion 12. U-shaped insert
80 includes first and second U sides 82, 90, each of which include an outer U side
84, 92; an inner U side 86, 94; and a U top 88, 96. First and second U sides 82, 90
are connected by connecting portion 98, which has a wrist end side 100 near the wrist
end 70 of gripping portion 12, and a gap side 102 near gap 104. The wrist end side
100 connects outer U sides 84, 92 of first and second U sides 82, 90. The gap side
102 connects inner U sides 86, 94 of first and second U sides 82, 90. Gap 104 is the
space between first and second U sides 82, 90 and connecting portion 98. First and
second U outer sides 84, 92 are contoured to follow concave contour 16 of first and
second sides 76, 78 of gripping portion 12. First and second U sides 82, 90 and connecting
portion 98 form the U-shaped insert 80 so that when U-shaped insert 80 is disposed
between halves 71, 73, gripping portion 12 includes three layers of material at first
and second U sides 82, 90 and connecting portion 98. At gap 104, gripping portion
12 only includes two layers of material, namely halves 71, 73.
[0046] Gripping portion 12 includes finger end 18, which is the end of gripping portion
12 that covers the user's fingers. End piece 20 is disposed at finger end 18 of the
preferred gripping portion 12. End piece 20 is preferably stiff, but flexible, and
is preferably rectangular. End piece 20 is disposed within gripping portion 12 by
any means commonly used in the art, but preferably by holding it in place between
the layers of gripping portion 12 by stitching around end piece 20 and affixing it
in place using an adhesive. However, in molded embodiments of the invention, such
as is discussed below with reference to FIG. 4, the end piece 20 is molded integral
to the gripping portion 12.
[0047] When grip assist apparatus 10 is in use, wrist portion 28 securably and releasably
wraps around the user's wrist. Wrist portion 28 includes first and second straps 30,
31, which are both preferably rectangular in shape. First strap 30 has free end 34
and attachment end 32, attached to first attachment edge 72 of gripping portion 12.
Second strap 31 has free end 35 and attachment end 33, attached to second attachment
edge 74 of gripping portion 12. Strap attachment ends 32, 33 may be attached to attachment
edges 72, 74 by any means commonly used in the art, but preferably by inserting strap
attachment ends 32, 33 between the halves 71, 73 of gripping portion 12 at the attachment
edges 72, 74 and affixing strap attachment ends 32, 33 there by stitching and or gluing
or other adhesion. Straps 30, 31 are attached to gripping portion 12 at angle A, which
is preferably about 120°. Angle A may be greater or less than 120°, however, depending
on the user's hand. Angle A may be customized to best fit the user's hands and to
ensure a comfortable fit on either hand. Although straps 30, 31 are not identical
in the preferred embodiment, because of the symmetry of gripping portion 12, either
strap 30, 31 may be attached to either attachment edge 72, 74. In the preferred embodiment,
straps 30, 31 include cushioned pads 38 for the comfort of the user. Cushioned pads
38 are preferably formed of foam rubber covered by a low friction fabric. This is
preferred because the fabric covering over the foam rubber allows the straps 30, 31
to slide over the cushioned pads 38 and prevents it from gripping onto the foam rubber.
[0048] Straps 30, 31 also include a wrist fastener 36 to fasten wrist portion 28 about the
user's wrist. Wrist fastener 36 preferably includes a first section 42 that includes
a ring 44 at the strap free end 34 of one of first strap 30. Wrist fastener 36 also
preferably includes a second section 46 on second strap 31, which may be inserted
through ring 44 to secure wrist portion 28. Second section 46 preferably includes
a first length 48 of loop-type fastener and a second length 50 of hook-type fastener
so that when second strap 31 on which second section 46 is disposed is inserted through
ring 44, first length 48 and second length 50 may be joined and releasably secured.
[0049] Now referring to FIG. 4, the preferred gripping portion 12 before it is folded is
illustrated. Gripping portion 12 is preferably made of a non-slip piece of material
40, such as chlorobutyl rubber, which provides a tacky, sticky surface to allow gripping
portion 12 to adhere to the palm of the user's hand instead of sliding around while
in use. Material 40 includes a first flat material side 504 and a second flat material
side, the second flat material side being understood to be the opposite side of side
504 and therefore facing away from the viewer. The piece of material 40 is non-slip
on at least the side that will face out when material 40 is folded. That is to say
that the side of the material 40 that will be folded and flush against itself may
or may not be non-slip material, but the side that faces out and will be in contact
with the user's hand and/or bars 66 (as shown in FIGS. 8 A and 8B) is preferably non-slip.
Gripping portion 12 is preferably formed by adhering two layers 71, 73 of appropriately
sized and shaped non-slip material together, preferably by folding over one piece
of non-slip material 40 at first line of symmetry 41, and stitching the two halves
71, 73 together. When first flat material side 504 is folded along first line of symmetry
41, both of layers 71, 73 will face out and second flat material side will face itself
and not be visible. In such a scenario, first flat material side 504, facing out,
is preferably non-slip. However, in one embodiment, the material is a moldable material,
such as urethane, molded rubber or others, that is molded into the shape of at least
the non slip gripping portion 12. When folded along first line of symmetry 41, gripping
portion 12 has a rigidity such that it is self-supporting and will remain extended
in front of the palm and of the fingers to allow gripping portion 12 to be manipulated
by the human hand on which grip assist apparatus 10 is worn. Despite this rigidity,
gripping portion 12 is sufficiently flexible to allow itself to be easily wrapped
around a lifting bar 66 using only the tip of a finger.
[0050] Now referring to FIG. 5, gripping portion 12 is shown superimposed over a hand. For
the sake of clarity, wrist portion 28 has not been included in FIG. 5, but is understood
to be present as shown in FIG. 3A. Although it is understood that U-shaped insert
80 is disposed between halves 71, 73, it is outlined to indicate its position within
gripping portion 12. Comparing FIGS. 2 and 5, it is clear that when gripping portion
12 is placed over a palm as intended, the following will be true: at least a portion
of first and second U tops, 88, 96 will be disposed over at least a portion of metacarpal
fat pad series 204; at least a portion of first U side 82 is disposed on top of at
least a portion of pinky fat pad 202; at least a portion of second U side 90 is disposed
on top of at least a portion of thumb fat pad 200; and at least a portion of connecting
portion 98 is disposed on top of at least a portion of both pinky fat pad 202 and
thumb fat pad 200. Again, it is arbitrary as to whether it is the first or second
U side 82, 90 that is disposed on top of the thumb or pinky fat pad 200, 202, as gripping
portion 12, including U-shaped insert 80 is symmetrical along second line of symmetry
14. Additionally and importantly, at least a portion of gap 104 is disposed on top
of at least a portion of area of vulnerability 206. These placements of the various
parts of U-shaped insert 80 ensure that more pressure is placed on the fahier parts
of the hand, namely the thumb fat pat 200, pinky fat pad 202, and metacarpal fat pad
series 204. Gap 104, surrounded by the area reinforced by U-shaped insert 80, will
keep bar 66 from coming into contact with area of vulnerability 206, thus eliminating
pressure on this unprotected and uncushioned portion of the hand and preventing injury.
[0051] Now referring to FIG. 6, preferred stitching 106 is illustrated. Stitching 106 is
the preferred method for securely affixing halves 71, 73 to one another. Other commonly
used methods of affixation, such as gluing or other adhesive may also be used. In
embodiments where gripping portion 12 is a singled molded piece, no such affixation
is necessary. In FIG. 6, except for the perimeter of gripping portion 12, solid lines
indicate lines of stitching 106. Dotted lines indicate second line of symmetry 14,
the position of end piece 20, the position of U-shaped insert 80, and first and second
straps 30, 31. Stitching 106 includes at least first outer section 108, second outer
section 110, first inner section 112, second inner section 114, first top section
116, second top section 118, and gap defining section 120. As shown, it is also preferred
that first and second outer sections 108, 110 extend downward and meet near wrist
end 70 of gripping portion 12 and that additional stitching is included to secure
straps 30, 31 to first and second attachment edges 72, 74. First and second outer
sections 108, 110 follows concave contour 16 of first and second sides 76, 78 of gripping
portion 12, extending up toward finger end 18 and down toward first and second attachment
edges 72, 74 and wrist end 70. First outer section 108 is between first side 76 of
gripping portion 12 and first U outer side 84 of U- shaped insert 80. Therefore first
outer section 108 is stitching through only first and second halves 71, 73. Second
outer section 110 is between second side 78 of gripping portion 12 and second U outer
side 92 of U-shaped insert 80. Therefore second outer section 110 is stitching through
only first and second halves 71, 73. First inner section 112 is inside of first U
outer side 84 of U-shaped insert 80. Therefore first inner section 112 is stitching
through first and second halves 71, 73, as well as U-shaped insert 80. Second inner
section 114 is inside of second U outer side 92 of U-shaped insert 80. Therefore second
inner section 114 is stitching through first and second halves 71, 73, as well as
U-shaped insert 80. First and second top sections 116, 118 are stitching just above
the tops of first and second U tops 88, 96, respectively, and are therefore stitching
through only first and second halves 71, 73. Finally, gap defining section 120 follows
first U inner side 86, gap side 102, and second U inner side 94, just within gap 104,
so that gap defining section 120 is also stitching through only first and second halves
71, 73. The combination of stitching sections 108-120, particularly with first and
second inner sections 112, 114 being through U-shaped insert 80 as well as halves
71, 73, while all other sections are through halves 71, 73 only, holds U-shaped insert
80 in place, securely holds halves 71, 73 against one another, and clearly defines
gap 104.
[0052] Now referring to FIG. 7, because straps 30, 31 are attached to gripping portion 12
at angle A (shown in FIG. 3A), they form a funnel-like opening 60 when attached to
one another. Funnel-like opening 60 serves to grab the user's wrist in order to provide
a firm support during strength training. Funnel-like opening 60 has a distal end 62
positioned around the base of the user's hand and a proximal end 64 positioned around
the user's wrist. As distal end 62 is larger than proximal end 64, chafing of the
base of the hand is prevented. Moreover, the nature of funnel-like opening 60 prevents
circulation from being restricted in the user's hand while enabling grip assist apparatus
10 to be firmly attached to the user's wrist. It is noted that positioning the funnel
like opening 60 about the base of the hand is preferred when the gripping apparatus
is used during pulling exercises. However, when performing pushing exercises, the
funnel like opening 60 is preferably positioned about the user's wrist and tightened
to provide wrist support.
[0053] Now referring to FIGS. 8A and 8B, front views of a human hand loosely holding a bar
with the grip assist apparatus 10 are provided. In FIG. 8 A, gripping portion 12 is
between the bar 66 and the user's hand 68. In FIG. 8B, bar 66 is between gripping
portion 12 and the user's hand 68. Thus the user may customize his use of grip assist
apparatus 10 to what is most comfortable for him. In particular, the use shown in
FIG. 8A may be more comfortable for pushing exercises, such as the bench press or
chest press. The use shown in FIG. 8B may be more comfortable for pulling exercises,
such as a chinup or the lat pulldown.
[0054] Now referring to FIGS. 9A and 9B, a progression of use from FIG. 8B are provided.
In FIG. 9B, a side view of a human hand 68 curling the finger end 18 of gripping portion
12 around the bar 66 toward the hand 68 is provided. In FIG. 9B, a perspective view
of a human hand 68 gripping the gripping portion 12 around the bar 66 after the position
shown in FIG. 9A is provided. It is understood that a similar progression of use may
occur starting with the use shown in FIG. 9A with the gripping portion 12 between
bar 66 and hand 68. In other words, the user has the option of gripping bar 66 with
gripping portion 12 curling away from hand 68, as suggested by FIG. 8A, or curling
toward hand 68, as shown in FIGS. 9A and 9B.
[0055] Referring now to FIG. 10, an alternative arrangement is shown in which the gripping
portion 12 is integrated into a weightlifting glove 300. In such arrangements, the
wrist portion of other embodiments is eliminated and is replaced by a glove 300 made
of a flexible material that is shaped and dimensioned to cover the user's palm and
at least a portion of each finger.
[0056] In the arrangement of FIG. 10, the glove material 302 covering the user's palm forms
the first layer of the gripping portion 12, the insert 80 is outlined to indicate
its position within gripping portion 12 and is positioned upon this layer of glove
material 302 and secured in position thereon by an outer layer 43. Comparing FIGS.
2 and 10, it is clear that when the glove 300 is worn, the gripping portion 12 is
disposed over a palm such at least a portion of first and second U tops, 88, 96 will
be disposed over at least a portion of metacarpal fat pad series 204; at least a portion
of first U side 82 is disposed on top of at least a portion of pinky fat pad 202;
at least a portion of second U side 90 is disposed on top of at least a portion of
thumb fat pad 200; and at least a portion of connecting portion 98 is disposed on
top of at least a portion of both pinky fat pad 202 and thumb fat pad 200, and at
least a portion of gap 104 is disposed on top of at least a portion of area of vulnerability
206. These placements of the various parts of U-shaped insert 80 ensure that more
pressure is placed on the fattier parts of the hand, namely the thumb fat pat 200,
pinky fat pad 202, and metacarpal fat pad series 204. Gap 104, surrounded by the area
reinforced by U-shaped insert 80, will keep bar 66 from coming into contact with area
of vulnerability 206, thus eliminating pressure on this unprotected and uncushioned
portion of the hand and preventing injury.
[0057] Referring now to FIGS. 11 A and 11B, in some embodiments in which the gripping portion
12 is integrated into a weightlifting glove 300, the gripping portion 12 is formed
by adhering two layers 71, 73 of appropriately sized and shaped non-slip material
together with the insert 80 disposed therebetween. As shown in FIG. 11B, the outer
layer 73 is manufactured from a wider sheet of material to allow it to be wrapped
over the insert 80 and secured to the inner layer 71. Once so secured, the gripping
portion 12 is attached to the glove material 302 in the position shown in FIG. 10.
It is noted that FIGS. 10 and 11A show a U-shaped insert 80. However, it is understood
that any of the insert shapes disclosed herein may be substituted to achieve similar
results.
