Background
[0001] The present invention relates generally to bundling, fastening, or securing devices
and, more particularly, to adjustable strap-like securing devices.
[0002] Ropes, straps, and cords are known for securing and bundling items. Straps, such
as tie-down straps, and elastic cords, such as bungee cords, are often used to secure
or bundle items such as luggage, cargo, or equipment during transport. Such straps
and cords are also used to secure or close items such as tarps, clothing, backpacks,
duffel bags, chin straps for helmets, pet collars, or to bundle items such as sleeping
bags, yoga mats, extension cords, yard tools or camping gear. To allow the length
of a strap to be adjusted, the strap may be provided with a so called "ladder-lock"
through which the strap is threaded. In addition, to allow the ends of a strap to
be quickly connected and released, a strap may be provided with a buckle, such as
a side release buckle. Similarly, the ends of bungee cords may be provided with hooks,
snaps or clips to allow the ends of the cords to be quickly connected and disconnected
from each other or an anchoring surface.
[0003] Strap and cord devices are also known in the prior art.
U.S. Patent No. 4,149,540 (Hasslinger) for example, discloses a separable fastening device adapted to encompass at least
one member in gripped relation having a fist flexible strap having on one surface
a plurality of upstanding hook-and-loop type engaging elements, a second strap having
on a surface opposite the first surface, a plurality of mating upstanding hook-and-loop
type engaging element, with means being provided to connect the first and second straps,
and retaining means connected to the free end of the first strap, the retaining means
defining an opening configured to receive the free end of the second strap.
U.S. Patent No. 6,345,418 (Bertrand, et. al.) discloses a rope hook comprising a length of tubular fabric webbing into which a
pair of loops has been formed.
U.S. Patent No. 6,014,794 (McCoy) discloses a reinforced bungee cord tie down for securing cargo without becoming
over-stretched. And
U.S. Patent No. 6,546,604 (Galkiewicz, et. al.) discloses a self mating mechanical fastener comprising a base sheet and a multiplicity
of parallel, narrowly spaced, elastically deformable ribs projecting from the base
sheet.
Summary
[0004] Existing straps and cords suffer from numerous drawbacks and shortcomings. For example,
straps with conventional buckles, such as ladder-lock buckles and side release buckles,
are difficult to thread and adjust, can pinch user's fingers, have a limited range
of adjustability, and tend to slip and, therefore, not hold securely. In addition,
existing straps and cords are complicated and expensive to make, and are prone to
wear and tear and, thus, are prone to premature failure. Bungee cords have a limited
range of adjustability, recoil violently after being stretched and released, lose
their elasticity over time, and - because of their elasticity - do not hold securely.
The need exists for an adjustable strap device that is versatile, holds securely,
is easy to make, and is easy to use.
[0005] In one embodiment, the present disclosure provides a securing device comprising a
strap having opposed first and second major surfaces and first and second ends, wherein
at least one of the first and second major surfaces includes a fastener, and a buckle
attached to the strap, wherein the buckle includes a body containing an opening for
receiving the strap, and wherein the buckle includes a buckle fastener arranged for
refastenable mating engagement with the strap fastener.
[0006] In a more specific aspect, the body may include a first portion and a second portion
spaced from the first portion, thereby defining an opening between the first portion
and the second portion. In another aspect, the body may further include at least one
neck portion extending between the first portion and the second portion.
[0007] In one embodiment, the buckle has first and second major surfaces, and the first
and second major surfaces may be coplanar. In another aspect, the buckle first body
portion and second body portion may be generally coplanar. In another embodiment,
the buckle may have a generally thin, flat, plate-like configuration. In another embodiment,
the buckle may have a curved configuration.
[0008] In one embodiment, the opening for adjustably receiving the strap may be bound on
all sides, and the strap may be connected with the buckle by threading the strap through
the opening. The opening is generally configured to slidably and removably receive
the strap to allow the length and position of the strap to be readily adjusted. In
a specific aspect, the buckle includes first and second sides, and the opening may
extend from one side, thereby forming a slot having a mouth, whereby the strap may
be inserted laterally into the slot via the mouth.
[0009] In other aspects, the buckle may include a reinforcing rib portion extending along
a side of the buckle opposite the opening, and/or the first portion may contain a
second opening, wherein a first end of the strap may be secured to the buckle first
portion via the second opening.
[0010] In other aspects of specific embodiment, the buckle fastener may be arranged on a
surface of the buckle second body portion, the strap fastener may comprise a plurality
of fastening elements, the buckle fastener may comprise a plurality of fastening elements,
and the buckle fastener may comprise a patch of fastening elements having an area
of at least about 1 cm
2 and no greater than about 25 cm
2, and a length of at least about 1 cm and no greater than about 8 centimeters as measured
along the longitudinal length of the strap.
[0011] In one embodiment, the buckle fastener may be adhesively bonded to the buckle second
body portion. In other embodiments, the strap fastener may form a first attachment
surface, and the buckle fastener may form a second attachment surface. In a specific
embodiment, the strap first major surface may be provided with loop material, and
the first major surface of the buckle second body portion may be provided with hook
material. In another embodiment, strap fastening elements and the buckle fastening
elements may be self-mating.
[0012] In another embodiment, the second body portion may be arranged at an angle relative
to the first body portion. The first body portion and the second body portion may
form an angle of about 45 degrees to about 180 degrees. In addition, the strap and
the second body portion may form an angle of between about 0 degrees and about 135
degrees. In one embodiment, the first body portion may be configured to be mounted
on a surface such that when the first body portion is mounted on a surface, the second
body portion extends outwardly away from the mounting surface.
[0013] In other embodiments, the buckle may include a foot portion extending from the first
body portion. The foot portion may extend outwardly from the first body portion in
the same direction as the second body portion. The foot portion may extend outwardly
from an end of the first body portion opposite the second body portion at an angle
of about 90 degrees, thereby forming a ledge. The foot portion may include an opening,
and one end of the strap may be secured to the foot portion via the opening. In various
embodiments, the buckle may include a reinforcing side wall portion extending between
the first body portion and the second body portion.
[0014] In one aspect of the invention, the strap second major surface may be substantially

Detailed Description
[0018] Referring now to the drawings, wherein like reference numerals refer to like or corresponding
parts throughout the several views, FIGS. 1-3, show a securing device 2 including
a strap 4 and a buckle 6. The strap 4 and buckle 6 include fasteners 8, 10, respectively,
arranged for refastenable mating engagement, thereby to allow the strap 4 to be repeatably
connected and disconnected from the buckle 6. The strap 4 includes opposed first and
second major surfaces 12, 14, respectively, and first and second ends 16, 18, respectively,
and the buckle 6 includes first and second major surfaces 20, 22, respectively, and
first and second ends 24, 26, respectively. In the illustrated embodiment, the first
end 16 of the strap 4 is fixedly connected with the first end 24 of the buckle 6.
[0019] The buckle 6 comprises the buckle fastener 10 and a body 28. The body 28 comprises
a first portion 28a, and a second portion 28b spaced from the first portion 28a, thereby
defining an opening 30 between the first portion 28a and the second portion 28b. In
the illustrated embodiment, the body 28 includes a neck portion 28c extending between
the first portion 28a and the second portion 28b, whereby the opening 30 is a slot
open at one end and, thereby, configured to slidably and removably receive the strap
4 from the side without threading the strap 4 through the opening 30. That is, the
buckle 6 includes first and second sides 32, 34, respectively, and the opening 30
extends from the first side 32 toward the second side 34 of the buckle 6 between the
first and second portions 28a, 28b, and in the direction of the neck portion 28c,
thereby forming a slot 30 having a mouth 30a, whereby the strap 4 can be inserted
laterally into the slot 30 via the mouth 30a. It will be recognized that in another
embodiment, the opening 30 may be bound on all sides, whereby the strap 4 is connected
with the buckle 6 by threading the strap 4 through the opening 30.
[0020] In the embodiment illustrated in FIGS. 1-3, the first and second major surfaces 20,
22 of buckle 6 are generally coplanar, and the first and second portions 28a, 28b
of the body 28 are generally coplanar. That is, the buckle 6 has a generally thin,
flat, plate-like configuration. It will be recognized that in other embodiments the
buckle 6 may be curved.
[0021] In the illustrated embodiment, the buckle 6 further comprises a reinforcing rib portion
28d that extends along the second side 34 of the buckle 6 adjacent the neck portion
28c. It will be recognized that the reinforcing rib portion 28d need not extend along
the entire length of the second side 34 of the buckle 6 to perform the desired function
of providing additional strength. That is, the reinforcing rib portion 28d may extend
along the second side 34 only along the neck portion 28c and a portion of the first
and second body portions 28a, 28b.
[0022] In the illustrated embodiment, the first body portion 28a contains a second opening
36, and the first end 16 of the strap 4 is secured to the first body portion 28a of
the buckle 6 via the second opening 36. More specifically, the first end 16 of the
strap 4 is threaded through the opening 36 contained in the first body portion 28a
of the buckle 6 and looped back onto itself, and secured to itself. The strap 4 may
be secured to itself using known fasteners such as, for example, adhesive, a rivet
or stitching 38, thereby providing a generally fixed connection between the first
end 16 of the strap 4 and the first body portion 28a of the buckle 6.
[0023] The strap and buckle fasteners 8, 10 may be, for example, an adhesive, such as non-tacky
adhesive, a permanent or repositionable adhesive, or a mechanical fastener including
snaps, clips, hooks, buttons, hook-and-loop fasteners, self mating mechanical fasteners,
and the like. In the illustrated embodiment, the strap fastener 8 is arranged on the
first major surface 12 of the strap 4, and the buckle fastener 10 is arranged on the
first major surface 20 of the second body portion 28b of the buckle 6. The buckle
fastener 10 may be, for example, adhesively bonded to the first major surface 20 of
the second body portion 28b of the buckle 6, and the strap fastener 8 may be adhesively
bonded or sewn to the strap 4. Alternatively, the strap fastener 8 may be formed as
part of the strap 4 itself. That is, the strap fastener 8, such as a loop material,
may be woven and incorporated directly into the strap 4 itself. In the illustrated
embodiment, the strap fastener 8 and buckle fastener 10 comprises a plurality of fastening
elements that form an attachment surface or patch of fastening elements.
[0024] In the illustrated embodiment, the plurality of fastening elements forming the buckle
fastener 10 are provided on substantially all of the first major surface 20 of the
second body portion 28b of the buckle 6. Depending on the intended end use application
and the amount of holding force desired, the patch of fastening elements provided
on the buckle 6 that form the buckle fastener 10 may cover a surface area of at least
about 1 square centimeters (cm
2), at least about 2 cm
2 or at least about 3 cm
2, and may cover a surface area of no greater than about 20 cm
2, no greater than about 25 cm
2 or no greater than about 30 cm
2. One advantage of the present invention is that is does not require a large amount
of fastening elements on the buckle 6. For example, in various embodiments, buckle
fastener 10 may have a length of no greater than about 8 centimeters (cm), no greater
than about 5 cm, no greater than about 2.5 cm, no greater about 2 cm, or no greater
than about 1 cm as measured along the longitudinal length of the strap 4.
[0025] In the illustrated embodiment, the first major surface 20 of the buckle 6 second
body portion 28b is provided with hook material, and the first major surface 12 of
the strap 4 is provided with loop material, thereby providing a hook-and-loop type
mating surface between the buckle 6 and the strap 4. In another embodiment, the positions
of the hook-and-loop material may be reversed. That is, hook material may be provided
on the strap 4, and loop material may be provided on the buckle 6. Other mechanical
fasteners such as self-mating reclosable mechanical fasters may also be used. Such
fasteners are described in, for example,
U.S. Patent No. 5,077,870 (Melbye et. al.), the entire contents of which are hereby incorporated by reference.
[0026] The buckle 6 may be formed of a variety of materials. The particular material selected
is not significant to the invention hereof, so long as it provides the requisite strength
and desired function. Suitable materials include, for example, wood, metal, or a rigid
synthetic plastic material.
[0027] Referring generally to FIGS. 4 and 5, wherein functionally similar features to those
in FIGS. 1-3 are referred to with like reference numerals incremented by 100, there
is shown a bracket or buckle 106 having a body 128 wherein the second body portion
128b of the buckle 106 is arranged at an angle relative to the first body portion
128a of the buckle 106. To allow the details of the buckle 106 to be seen more clearly,
a strap is not shown in FIGS. 4 and 5.
[0028] Referring more specifically to the embodiment illustrated in FIG. 4, there is shown
a buckle 106 including a body member 128 and a buckle fastener 110. The body 128 includes
a first body portion 128a, a second body portion 128b, and a reinforcing side wall
portion 128e. The first body portion 128a contains an opening 136 which is used to
secure a strap to the buckle 106, and the buckle 106 contains a slot 130 for adjustably
receiving a strap (not shown in FIG. 4).
[0029] Referring more specifically to the embodiment illustrated in FIG. 5, there is shown
a buckle 106 including a body member 128 and a buckle fastener member 110. The body
128 includes a first body portion 128a, a second body portion 128b, a reinforcing
side wall portion 128e, and a foot portion 128f that extends from an end of the first
body 128a portion in the same direction as the second body portion 128b. In the illustrated
embodiment, the foot portion 128f extends outwardly from an end of the first body
portion 128a opposite the second body portion 128b at an angle of about 90 degrees,
thereby forming a ledge that can be used to support items prior to the items being
secured or bundled with a strap. The foot portion 128f contains an opening 136 that
is used to secure a strap to the buckle 106. That is, a strap is secured to the foot
portion 128f via the opening 136.
[0030] Referring to FIG. 6, there is shown a securing device 102 mounted on a mounting surface
50. The securing device 102 includes a bracket or buckle 106 and a strap 104. In the
illustrated embodiment, the first body portion 128a and the second body portion 128b
form an angle α that can range from 0 to about 170 degrees. That is, when the securing
device 102 is mounted on a mounting surface 50 and the first body portion 128a is
mounted flush on the mounting surface 50, the second body portion 128b extends outwardly
away from the mounting surface to allow enough room so the strap 104 can be maneuvered
and secured to the buckle fastener 110. It has been found that smaller angles α may
provide increased holding strength. Thus, angles α ranging less than 135 degrees,
less than 90 degrees, or less than 45 degrees are desirable. In addition, when the
strap 104 is secured to the buckle 106 via the buckle fastener 110 by arranging the
strap 104 in the slot 130 and attaching the strap fastener 108 to the buckle fastener
110, the strap 104 and the first body portion 128a form an angle β of between about
0 degrees and about 135 degrees.
[0031] The buckle 106 may be mounted to the mounting surface 50 in a conventional manner
using, for example, glue, a hot melt adhesive, a permanent pressure sensitive adhesive,
or a stretch removable adhesive, such as Command adhesive strips available from 3M
Company, St. Paul, Minnesota. Alternatively, the buckle 106 may be secured to the
mounting surface 50 through openings 52 provided in the first body portion 128 using
mechanical fasteners 54 such as nails or screws.
[0032] In each of the embodiments described herein, the length of the strap 4 is not significant
to the invention hereof, as long as it provides the desired function of being able
to bundle or secure one or more items for a given end use application. The strap 4
may have a length of, for example, at least about 8 inches, at least about 12 inches,
or at least about 16 inches. In addition, the material used to form the strap 4 is
not significant to the invention as long as it provides the desired properties, such
as strength and/or flexibility, for a given end use application. Suitable materials
include, for example, cotton, nylon, polypropylene, polyester, and combinations thereof.
[0033] In accordance with an advantage of the embodiments described herein, the second major
surface 14 of the strap 4 may be substantially free of fasteners elements. That is,
in contrast to known straps that require interlocking fasteners on substantially all
of both opposed major surfaces of the strap to allow for the desired degree of holding
strength and adjustability, the embodiments described herein may include fasteners
on only one major surface of the strap. That is, one major surface of the strap may
be substantially free of fasteners. Rather than provide the second, or mating, fastener
on the opposed major surface of the strap, the second, or mating fastener, is provided
on the buckle. In addition, the surface area covered by the fastener on the buckle
is significantly less than the surface area of the fastener provided on the strap.
Surprising, it has been found that even when the second, or mating fastener or fastening
elements are provided only on the buckle, and the surface area covered by fasteners
on the buckle is significantly less than the surface area covered by fasteners on
the strap, full adjustability and strong holding power can be maintained. Another
benefit of providing the mating fastening elements on the buckle is that significantly
less fastening material is needed to form the fastener or mating surface, and, hence,
the overall cost of the raw materials used to produce the securing device is reduced.
It will be recognized that the second major surface 22 of the buckle 6 may be substantially
free of fastening elements.
[0034] Depending on the desired extent of adjustability, the strap fastener 8 may provided
on only a portion of the first major surface 12 of the strap 4 or, if maximum adjustability
is desired, on substantially all of the first major surface of the strap first major
surface 12.
[0035] Persons of ordinary skill in the art may appreciate that various changes and modifications
may be made to the invention described above without deviating from the inventive
concept. For example, in one aspect, it will be recognized that a strap, while useful
in forming a securing device, it is not a required element of the invention. That
is, a buckle according to the present invention may be initially provided without
a strap, and straps having various properties or characteristics such as, for example,
different lengths, colors, or strengths, may be provided separately. Thus, the scope
of the present invention should not be limited to the structures described in this
application, but only by the structures described by the language of the claims and
