BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a separable fastener which is in the form of a
cinch strap.
2. Description of the Prior Art
Separable fasteners such as those described in U.S. Pat. Nos. 2,717,437 and
3,009,235 which are marketed under the registered trademark VELCRO brand
hook and loop fasteners by Velcro Corporation, 681 Fifth Avenue, New York,
N.Y. have gained wide acceptance because of the properties of the mating
hooks and loops which permit their attachment by merely placing a surface
defined by the hooks into face-to-face relationship with a surface defined
by the loops so that a large number of hooks engage a large number of
loops which resist separation parallel to the interfacial plane of
engagement but are readily separable by peeling forces applied
substantially normal to this interfacial plane. These fastening devices
are generally formed of a sheet of synthetic woven or knitted fabric
having raised threads of synthetic material, such as nylon, which are
napped or unnapped to provide a pile surface defined by a plurality of
loops, and which may be thermally treated to become semi-rigid. Certain of
the loops may then be cut along one side near their outer extremity to
form hooks.
These fasteners have been utilized in numerous applications in many fields
of use, particularly because of their unique touch and close fastener
capability as well as their fastening strength. The patents which have
issued are legion in which the unique fastening capability of these hook
loop-type engaging elements have been applied to particular uses to create
new and unobvious fastener arrangements.
One field of use in which these fasteners have been utilized in the past
pertains to straps of several types. Although the prior art dealing with
straps and the like includes numerous other fastener devices to secure the
straps in their intended environment, the applications of these separable
hook and loop-type fasteners have in many respects, eliminated the need
for the traditional strap fastening devices such as buckles and the like.
To the extent that the early fastening devices did not generally
facilitate variable and precise fastening, the application of these
separable fasteners to the strap art has proven to provide substantial
advantages.

relatively complex and expensive construction and which utilizes a
relatively complex buckle for fastening the device in position. U.S. Pat.

U.s. pat. No. 3,669,096 to Hurwitz
U.s. pat. No. 3,880,161 to Fossell
In the prior art applications of VELCRO.RTM. brand fasteners to straps and
the like, the structure has always been adapted such that the hook and
loop-type fasteners are secured by a touch and close action. None of these
patents disclose a cinch fastener which is so constructed and arranged to
facilitate fastening the hook and loop-type fastener materials with
multidirectional opposed cinching forces with a single movement in which
the gripping tension forces as well as the retention of said forces is
accomplished without loss of grip.
SUMMARY OF THE INVENTION
The present invention relates to a separable fastening device adapted to
encompass at least one member in gripped relation which comprises a first
flexible strap portion having on a first surface portion a plurality of
engaging elements upstanding therefrom and a second strap portion having
on a surface portion opposite said first surface portion a plurality of
mating engaging elements upstanding therefrom. The invention further
comprises means to connect the first and second strap portions and
retaining means connected to the free end portion of said first strap
portion, the retaining means defining an opening configured to receive the
free end portion of the second strap portion. The opposed positions of the
mating engaging elements are such that when the device is positioned about
the member with the free end portion of the second strap portion extending
through the retaining means, at least retaining the retaining means in a
substantially fixed position and applying cinching forces to the free end
portion of the second strap portion will cause the device to grip at least
a portion of the member, and substantially simultaneously pressing the
surfaces of mating engaging elements in face-to-face relation provides
face-to-face engagement of the strap portions to retain the grip thereby
applied.
The preferred embodiment of the invention in one of its broadest forms
relates to a separable fastening device adapted to encompass at least one
member in gripped relation which comprises a cinch strap including a main

the main strap portion at one end portion thereof and the other being
free. The retaining means defines an opening configured to receive the
free end portion of the main strap portion while the adjacent opposed
positions of the mating engaging elements are such that when the main
strap portion is positioned about the member with the free end portion
extending through the retaining means, at least retaining the retaining
means in a substantially fixed position and applying cinching face to the
free end portion of the main strap portion will cause the strap to grip at
least a portion of the member and substantially simultaneously pressing
the surfaces of the mating engaging elements in face-to-face relation
provides face-to-face engagement of the strap portions to retain the grip
thereby applied.
Although one preferred embodiment of the fastening device of the invention
utilizes a ring-like member to transmit retaining forces to a strap
portion, another embodiment includes a retaining strap connected to a main
strap portion to provide transmission of cinching forces thereto. This
particular embodiment is also in the form of a separable fastening device
comprising a cinch strap assembly adapted to encompass at least one member
in gripped relation and to provide simultaneous cinching and fastening
forces which substantially maximize the grip while uniquely retaining the
forces applied to the strap. This fastener device comprises a cinch strap
assembly which includes a main flexible strap portion having on one
surface portion a plurality of resilient engaging elements upstanding
therefrom, and on an opposite surface of a strap portion adjacent thereto,
a plurality of resilient mating engaging elements upstanding therefrom.
The invention further comprises a retaining strap which, in a preferred
embodiment, is of sufficient length to provide convenient gripping
thereof, and which is preferably configured at an end portion to
facilitate gripping thereof. The retaining strap is connected to the main
strap portion at one end portion and the other end portion of the main
strap portion is free. The strap further comprises means to connect the
retaining strap to the main strap portion . The connecting means in this
embodiment defines an opening configured to receive the opposite -- or
free end -- portion of the main strap when it is wrapped in encompassing
relation with the member to be gripped. The mating engaging elements on
each mating surface portion of the main strap portion are so arranged that
when the strap is positioned about the member to be gripped, with the free
end portion extended through the opening of the connecting means, at least
retaining the retaining strap in a substantially fixed position, while
applying cinching forces to the free end portion of the main strap causes
the strap to grip at least a portion of the member while substantially
simultaneously pressing the surfaces of resilient mating engaging elements
in face-to-face a relation provides face-to-face engagement of these strap
portions. This mating engagement is relatively resistant to forces
parallel to, or within the plane of engagement, but the surfaces are
readily separable by peeling forces normal to the interfacial plane of
engagement. This fastening capability retains the strap portions in
face-to-face relation to retain the grip thereby applied to the member.
Although the cinch fastener strap may be of a unitary construction,
preferably it is constructed of VELCRO.RTM. brand separable fastener tape
materials suitably secured to each other to provide the desired
arrangement. These separable fasteners to which I refer have a base
member, woven or knitted of a synthetic heat deformable material such as
nylon, and have resilient engaging elements uptanding from the respective
base member. In the preferred embodiment the engaging elements are
constructed in the form of hook-like elements which mate with looplike
hooking elements on the opposed engaging surface portions. However, it
should be understood that any flexible engaging elements, including
mushroom-like elements, resilient projections, etc., which are readily
securable in face-to-face relation, and which particularly resist forces
parallel to the interfacial plane of engagement, are comtemplated within
the scope of the present invention, provided the fastener st | | |
