Description
TECHNICAL FIELD
[0001] The present invention relates generally to weight-lifting
devices, and more specifically to a weight-lifting device adapted
to grasp and permit the rapid release, drop or disengagement of a
weight-bearing bar therefrom, wherein the weight or load carried by
the weight-bearing bar is effectively transferred to the user's
wrist(s), thereby significantly reducing or eliminating the amount
of hand strength or gripping force required to retain the bar
within the user's hand(s). The present invention is particularly
suitable for, although not strictly limited to, application within
the weight-training arena, wherein amateur weight-lifters and/or
professional bodybuilders alike may utilize the device to assist in
weight-training, weight-lifting, establishing proper lifting form,
and/or reducing exercise-induced bodily injury.
BACKGROUND OF THE INVENTION
[0002] For many individuals engaged in a regular exercise regimen,
weight-training is recognized as a crucial and effective method of
building muscle mass, improving muscle and bone strength, and
providing an overall low-impact cardiovascular exercise.
[0003] The vast majority of upper body weight-training exercises
are typically effectuated via the repetitive lifting and/or
directionally-concentrated displacement of a weight-bearing bar
carrying a selected number of calibrated weight plates thereon,
wherein the lifter usually grasps the weight-bearing bar with one
or both hands and retains the bar within his/her hand grip via a
sustained grasping hand force. However, because typical
weight-training regimens require multiple sets and repetitions of a
selected weight to effectively train a selected muscle group, such
sustained hand force around the weight-bearing bar can impart a
concentrated pressure on the lifter's palm(s), finger joints and/or
wrist(s), thus resulting in muscle and joint fatigue, and/or
potential injury thereto.
[0004] Accordingly, a multitude of available devices seek to reduce
or eliminate the amount of hand strength or gripping force required
to retain a weight-bearing bar within a lifter's hand(s), wherein
such devices either transfer the weight to the lifter's wrist(s)
and/or evenly distribute the pressure over the lifter's hand(s) and
wrist(s). An example of such a device includes straps or tethers of
sufficient length to securely wrap around the lifter's wrist and
the weight-bearing bar, thereby facilitating lifting of the bar.
Similar devices utilize straps to securely wrap around the lifter's
wrist, wherein a rigid hook-shaped support member, clasp or
carabiner carried by the strap is supportively engaged with the
weight-bearing bar. Still other devices utilize straps extending
from a glove worn by the lifter, wherein the straps similarly
securely wrap around the weight-bearing bar to facilitate lifting
of same.
[0005] Although the above-described available devices may
sufficiently transfer the weight of the weighted bar to the
lifter's wrist(s) and/or evenly distribute the pressure from same
over the lifter's hand(s) and wrist(s), such devices share a
disadvantageous commonality that renders use of each device highly
impractical and potential injurious to the lifter.
[0006] Specifically, to ensure the secured engagement of the straps
around the weight-bearing bar, the strap must often be tightly
wound multiple times around the bar and the lifter's wrist(s). As
such, should the lifter become fatigued or experience muscle
strain, utilization of such straps can prevent the lifter from
quickly releasing and dropping the bar from his/her person, thereby
subjecting the lifter to potential muscle and joint injury. Straps
with supportive hooks or carabiners also retard or prevent
quick-release and subsequent drop of the weight bar from the
lifter's person, wherein such hooks often possess a high degree of
curvature so as to securely retain or support the bar thereon, and
wherein carabiners, having a characteristic oblong ring-shape with
a spring-hinged side, lockingly receive and secure the bar
therewithin. Additionally, due to the inherent weight and resistive
forces of the weighted bar acting on the straps wrapped around the
lifter's wrist, the lifter's wrist is often subjected to
significant skin chafing, bruising, and potential impedance of
proper blood flow.
[0007] Therefore, it is readily apparent that there is a need for a
weight-lifting device that provides a user with the ability to
securely grasp a weighted bar, yet rapidly release and drop same
from the user's person. In addition thereto, there is a further
need for such a device that effectively transfers the weight or
load carried by the weight-bearing bar to the user's wrist(s),
thereby significantly reducing the amount of hand strength or
gripping force required to retain the bar within the user's
hand(s). There is yet a further need for such a device that
effectively transfers the weight or load carried by the
weight-bearing bar to the user's wrist(s), without subjecting the
user's wrist(s) to skin chafing, bruising, and/or potential
impedance of proper blood flow, due to the inherent weight and
resistive forces of the weighted bar acting thereon.
BRIEF SUMMARY OF THE INVENTION
[0008] Briefly described, in a preferred embodiment, the present
invention overcomes the above-mentioned disadvantages and meets the
recognized need for such a device by providing a weight-lifting
device and method of use therefor, wherein a user is able to
securely grasp a weight-bearing bar, yet rapidly release and drop
same from his/her person upon a sensation of fatigue or general
muscle strain, and wherein the present invention further
effectively transfers the weight or load carried by the
weight-bearing bar to the user's wrist(s), without subjecting the
user's wrist(s) to skin chafing, bruising, and/or potential
impedance of proper blood flow.
[0009] According to its major aspects and broadly stated, the
present invention in its preferred form is a weight-lifting
accessory or device and method of use therefor, comprising, in
general, a grapple assembly and wrist belt.
[0010] More specifically, the present invention is a weight-lifting
device and method of use therefor, preferably comprising a grapple
assembly possessing a series of cooperatively engageable grasping
and lifting members pivotally engaged to a support ring carried by
a wrist belt. The cooperatively engageable grasping and lifting
members of the grapple assembly preferably function according to
the principle of lifting tongs, wherein engagement of each member
over a weight-bearing bar, and subsequent upward displacement of
the grapple results in the grasping members "catching" the
weight-bearing bar, and thus, producing a tighter grip therearound
as the inherent weight/load and resistive forces of the bar
collectively downwardly bear against or act on each member, thereby
permitting the lifting of the weight-bearing bar via minimal
exertion of hand force by the user.
[0011] Preferably, each lifting member possesses a degree of
curvature sufficient to permit a weight-bearing bar to be grasped
and retained therewithin via minimal hand force, as described
above. However, the curvature of each lifting member is shallow
enough such that should the user/lifter become fatigued or sense
muscle strain during a particular exercise regimen, the user simply
releases his/her minimal hand grip, thus permitting the
weight-bearing bar to disengage from the grapple assembly.
Additionally, the present invention effectively evenly distributes
the weight and pressure, if any, from the weight-bearing bar over
the lifter's fingers and palms, and further transfers the weight of
the weight-bearing bar to the lifter's wrist via the communicating
wrist belt and support ring.
[0012] Accordingly, a feature and advantage of the present
invention is its ability to enable a user to securely grasp a
weight-bearing bar, yet to rapidly release and drop same from
his/her person, if desired.
[0013] Another feature and advantage of the present invention is
its ability to evenly distribute weight and pressure, if any, from
the weight-bearing bar over the lifter's fingers and palms.
[0014] Still another feature and advantage of the present invention
is its ability to effectively transfer the weight or load carried
by the weight-bearing bar to the user's wrist, without subjecting
the user's wrist to skin chafing, bruising, and/or potential
impedance of proper blood flow, as a result of the inherent weight
and resistive forces of the weighted bar acting thereon.
[0015] Yet another feature and advantage of the present invention
is its ability to assist a user with convenient and safe lifting of
dumbbell bars, curling bars, and/or other weight bearing bars.
[0016] These and other features and advantages of the present
invention will become more apparent to one skilled in the art from
the following description and claims when read in light of the
accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED AND SELECTED ALTERNATIVE
EMBODIMENTS
[0022] In describing the preferred and selected alternate
embodiments of the present invention, as illustrated in FIGS. 1-4,
specific terminology is employed for the sake of clarity. The
invention, however, is not intended to be limited to the specific
terminology so selected, and it is to be understood that each
specific element includes all technical equivalents that operate in
a similar manner to accomplish similar functions.
[0023] Referring now to FIGS. 1-3, the present invention in a
preferred embodiment is a weight-lifting device 10 and method of
use therefor, comprising wrist belt 20, support ring 30, and
grapple assembly 40.
[0024] Wrist belt 20 preferably includes first end 22 and second
end 24, wherein first end 22 preferably supports conventional belt
buckle member 26 with prong 27 engaged therewith, and wherein
second end 24 preferably possesses a plurality of aligned
throughholes 28 formed therethrough. Wrist belt 20 is preferably
secured to a user's wrist via threading second end 24 through
buckle member 26 of first end 22, wherein prong 27 of buckle member
26 is preferably inserted through a selected throughhole 28 for
securely fastening wrist belt 20 around the user's wrists, and
wherein second end 24 is subsequently threaded through belt loop 25
disposed on first end 22, proximal buckle member 26. Although the
foregoing buckle fastening system of wrist belt 20 is preferred, it
should be recognized that other suitable securing mechanisms could
be utilized, such as, for exemplary purposes only, hook-and-loop
fasteners, other buckle systems, clasps, latches, and the like.
[0025] Wrist belt 20 preferably possesses a sufficient width so as
to essentially cover the user's wrist and a portion just thereabove
(i.e., lower forearm), thereby providing ample support for the
user's wrist and further evenly distributing the weight and
pressure from a weight-bearing bar thereover. Additionally, and in
view of the relatively thin or overly malleable straps of available
weight lifting devices, wrist belt 20 is preferably formed from a
durable and relatively thick material, such as, for exemplary
purposes, leather, rubber, or the like, thereby further
contributing to the supportive and effective weight distributive
characteristics of wrist belt 20.
[0026] Preferably extending from lower edge 20a of wrist belt 20,
proximal the mid-region thereof, is support loop 29, wherein
support loop preferably securely retains support ring 30
therewithin. Support loop 29 is preferably secured to lower edge
20a of wrist belt 20 via any suitable securing means, such as, for
exemplary purposes only, stitching, hot melt, adhesives, rivets, or
integral formation therewith.
[0027] Support ring 30 is preferably substantially oblong
ring-shaped, comprising fulcrum portion 32 from which grapple
assembly 40 preferably securely extends, as more fully described
below. Support ring 30 is preferably formed from a suitable durable
material, such as, for exemplary purposes only, metal, plastic, or
the like. It should be recognized that support ring 30 could be
secured directly to wrist belt 20, or, alternatively, via clasps,
additional support rings, or the like, thereby eliminating
incorporation of support loop 29.
[0028] Referring now more specifically to FIG. 2, grapple assembly
40, shown removed from wrist belt 20 and engaged with support ring
30, preferably includes cooperatively engageable grasping and
lifting members 42, 44 and 46. Lifting members 42 and 46 preferably
possess first ends 42a and 46a, respectively, and second ends 42b
and 46b, also respectively, wherein first ends 42a and 46a are
preferably pivotally engaged about fulcrum portion 32 of support
ring 30. Lifting members 42 and 46 preferably flank lifting member
44, wherein lifting member 44 similarly preferably includes first
end 44a and second end 44b, and wherein first end 44a is also
preferably pivotally engaged about fulcrum portion 32 of support
ring 30.
[0029] Preferably, each lifting member 42, 44 and 46 is
substantially plate-like, and possesses a degree of curvature
sufficient to enable weight-bearing bar B to be grasped and
retained therewithin via minimal hand force, as more fully
described below with reference to FIG. 3. Additionally, to permit
effective cooperative engagement between lifting member 42, 44 and
46 over weight-bearing bar B, the geometry of curvature, or arc, of
lifting members 42 and 46 is preferably disposed within the same
plane, wherein the geometry of curvature of lifting member 44 is
preferably disposed in an opposing plane.
[0030] Referring now more specifically to FIG. 3, cooperatively
engageable grasping and lifting members 42, 44 and 46 of grapple
assembly 40 preferably function according to the principle of
conventional lifting tongs, wherein engagement of each member 42,
44 and 46 over weight-bearing bar B, and subsequent upward
displacement of grapple assembly 40 results in lifting members 42,
44 and 46 "catching" weight-bearing bar B, and thus, producing a
tightened grip therearound as the inherent weight or load and
resistive forces of bar B collectively downwardly bear against or
act on each lifting member 42, 44 and 46. As such, the user may
lift weight-bearing bar B utilizing minimal exertion of hand force,
as the weight of bar B is effectively transferred through grapple
assembly 40 to wrist belt 20 around the user's wrist. In such a
cooperatively engaged configuration, second end 44b of lifting
member 44 is preferably disposed between second ends 42b and 46b of
lifting members 42 and 46, respectively, wherein the overall degree
of disposition of second end 44b of lifting member 44 between
second ends 42b and 46b of lifting members 42 and 46, respectively,
will vary depending upon the overall diameter of bar B to which
lifting members 42, 44 and 46 are engaged.
[0031] During use of device 10, should the user/lifter become
fatigued or sense muscle strain during a particular exercise
regimen, the user simply releases his/her minimal handgrip over
grapple assembly 40, thus permitting the rapid disengagement and
dropping of weight-bearing bar B therefrom. Additionally, due to
the generally plate-like shape, preferred rigidity, and shallow
degree of curvature of each lifting member 42, 44 and 46, the
general curvature of grapple assembly 40 preferably conforms with
the user's open hand, thus resulting in a generally even
distribution of weight and pressure, if any, from weight-bearing
bar B over the lifter's fingers and palms. It should be recognized,
however, that the vast majority of weight and pressure from
weight-bearing bar B will preferably be transferred to the lifter's
wrist via the communicating wrist belt 20 and support ring 30.
[0032] Referring now more specifically to FIG. 4, illustrated
therein is an alternate embodiment of device 10, wherein the
alternate embodiment of FIG. 4 is substantially equivalent in form
and function to that of the preferred embodiment detailed and
illustrated in FIGS. 1-3 except as hereinafter specifically
referenced. Specifically, the embodiment of FIG. 4 incorporates
crossbar 50 formed between lifting members 42 and 46, proximal the
mid-regions thereof, wherein crossbar 50 provides rigidity between
lifting members 44 and 46, and further provides additional
supportive surface area for contacting weight-bearing bar B.
Crossbar 50 is located proximal the mid-regions of lifting members
44 and 46 so as to form a receiving area 52 between second ends 42b
and 46b of lifting members 44 and 46, respectively, wherein
receiving area 52 is sufficiently dimensioned to permit second end
44b of lifting member 44 to be cooperatively engaged therewithin
(i.e., disposed between second ends 42b and 46b of lifting members
44 and 46, respectively).
[0033] As further illustrated in FIG. 4, it is contemplated in
another alternate embodiment that the inner faces of each lifting
member 42, 44 and 46, and/or crossbar 50, could comprise a textured
coating or surface T to increase the frictional interaction of same
with a weight-bearing bar B grasped therebetween and therewithin.
Such textured surfaces could comprise, without limitation, rubber
pads, rubber coatings, and/or pads or coatings of rubber-composites
and/or other elastomeric compositions.
[0034] It is contemplated in still another alternate embodiment
that lifting members 42, 44 and 46 could be manufactured with any
selected degree of curvature or angle to facilitate the lifting of
weight-bearing bars having non-circular cross-sections, such as,
for exemplary purposes only, articles have hexagonal
cross-sections, octagonal cross-sections, square cross-sections, or
the like.
[0035] It is contemplated in still yet another alternate embodiment
that device 10 could be utilized to lift articles other than
weight-bearing bars, wherein lifting members 42, 44 and 46 could be
manufactured with any selected degree of curvature or angle to
facilitate the lifting of such articles.
[0036] It is contemplated in a further alternate embodiment that
device 10 could comprises any number of cooperatively engageable
lifting members, with or without crossbars formed therebetween.
[0037] It is contemplated in still a further alternate embodiment
that first ends 42a, 44a and 46a of lifting member 42, 44 and 46
could be spring-tensioned to permit the spring-forced grasping of
weight-bearing bar B therebetween, wherein release of bar B
therefrom could be facilitated via the user rapidly downwardly
jolting his/her arms and wrists so as to jolt bar B out from
grapple assembly 40.
[0038] It is contemplated in still yet a further alternate
embodiment that support loop 29 could be alternatively configured,
wherein support loop 29 could include rings or other suitable
fastening loops or members, and/or wherein support loop 29 in its
entirety could be replaced with rings or fastening loops for
effective support of support ring 30 and/or grapple assembly 40
thereby.
[0039] Having thus described exemplary embodiments of the present
invention, it should be noted by those skilled in the art that the
within disclosures are exemplary only, and that various other
alternatives, adaptations, and modifications may be made within the
scope of the present invention. Accordingly, the present invention
is not limited to the specific embodiments illustrated herein, but
is limited only by the following claims.
