Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to a system for releasing several
buckles simultaneously, using a single pull mechanism. The
invention releases several buckles that are each connected to a
cable by using a lever that causes each of the cables to be pulled
at the same time. The lever decreases the force required to release
the buckles, as compared to a direct pull on each of the
cables.
[0003] 2. The Prior Art
[0004] U.S. Pat. No. 6,487,761 to Van Tassel describes a buckle
system where the buckle is released by pulling a cable that is
attached to the male part of the buckle. U.S. patent application
Ser. No. 12/456,069 to Anscher, the disclosure of which is herein
incorporated by reference, shows a tactical vest having several
buckles attached, which are also connected to cables. A single pull
on a central handle pulls all of the cables simultaneously to
release all of the buckles at once. This is highly advantageous
when used on these types of vests, because the vest must often be
removed very quickly, such as in situations where the user is
submerged in water.
[0005] One disadvantage of the systems shown in these two patents,
however, is that a significant amount of force is required to
release the buckles. It would be desirable to provide a system that
reduces the amount of force required but avoids inadvertent release
of the buckles.
SUMMARY OF THE INVENTION
[0006] It is therefore an object of the invention to provide a
system that reduces the amount of force required to release a
cable-mounted buckle system having multiple buckles. It is another
object to provide a system that does not affect the structure or
manufacture of the buckles themselves, and which can be adapted for
use with one or several buckles. It is another object of the
invention to provide a system that is simple and inexpensive to
manufacture.
[0007] These and other objects are accomplished by a buckle release
system comprising a base plate, a fulcrum mounted on the base
plate, a lever pivotably mounted on the fulcrum, a handle connected
to the lever, at least one cable mounted to the lever at a location
remote from the handle, a buckle portion connected to each cable,
and a mating buckle portion releasably connected each buckle
portion. Pulling the handle pivots the lever and pulls the cables,
causing the buckle portions to release from each other. A cover
plate is also preferably mounted over the entire assembly to
prevent interference with the lever during use.
[0008] In a preferred embodiment, the cables are connected to male
buckle portions, which are configured to release from the female
buckle portions upon pulling of the cable. Examples of suitable
buckle portions are shown in U.S. Pat. No. 6,487,761 to Van Tassel,
U.S. patent application Ser. No. 12/456,069 to Anscher, and U.S.
patent application Ser. No. 12/661,308 to Anscher, all of which are
herein incorporated by reference.
[0009] In practical use, there are at least two cables connected to
the lever, and a buckle portion connected to each cable. This way,
pivoting the lever by pulling the handle releases multiple buckles
simultaneously. The use of the lever reduces the force required to
release the buckles, as a greater distance from the fulcrum on the
applied force size reduces the amount of force required to move the
lever. In one embodiment, there are four cables with buckles
connected to the lever. This embodiment allows the front and rear
sections of a tactical vest to be instantly separated from each
other if the system is mounted to either the front or rear of the
vest and the shoulder and waist sections of the vest are held
together with the buckles. Pulling on the handle causes all four
buckles to release simultaneously and cause the vest to separate,
thus instantly freeing the wearer.
[0010] There are many possible configurations of levers and cables
that are within the scope of this invention. In one embodiment, the
lever is a straight bar and the fulcrum is located between the
cable or cables and the handle. Thus, the cables are at one end,
the handle is at the other end, and the fulcrum is in the middle.
Pulling up on the handle causes the end of the lever with the
cables to move downward, thus pulling down on the cables and
releasing the buckles attached thereto. Thus, in this embodiment,
the cables and handle move in opposite directions.
[0011] In another embodiment, the fulcrum is disposed at one end of
the lever, the handle is disposed on an opposite end of the lever,
and the cables are disposed between the fulcrum and the lever.
Pulling up on the lever causes the cables to be pulled upward also.
This embodiment is useful if the cables need to be moved the same
direction as the direction of pulling on the handle.
[0012] The cables can be directly attached to the lever, or can be
indirectly connected via an attachment mechanism. The attachment
mechanism can be configured to receive one or several cables, and
is then pivotally mounted to the lever at the desired location. The
cables can be mounted in channels in the attachment mechanism. The
channels prevent the cables from crossing each other close to the
lever and interfering with the lever operation. The pivoting of the
attachment mechanism decreases the force applied to the system due
to cables coming in from different directions, and decreases the
risk of breakage.
[0013] In another embodiment, there can be two or more attachment
mechanisms connected to the lever. This way, the attachment
mechanisms can be mounted on opposite sides of the fulcrum, so that
pulling the handle pulls some of the cables in the same direction,
and pulls the other set of cables in the opposite direction. This
is useful when the device according to the invention is mounted in
between several buckles, some above and some below the attachment
mechanism. If the handle is configured to pull upward to move the
lever, the buckles above the attachment mechanism can be mounted on
the opposite side of the fulcrum from the handle and the buckles
below the attachment mechanism can be mounted on the same side as
the handle. This way, pulling the handle upward pulls the cables
for the top buckles downward, and pulls the cables for the bottom
buckles upward, to release all of the buckles at once with a single
movement. Alternatively, the cables can be directly mounted to the
lever in this way, without using the attachment mechanisms.
[0014] In another embodiment, the lever is L-shaped, and the
fulcrum is located at an elbow of the lever. This allows the cables
to be pulled in a direction that is perpendicular to the direction
of pull on the handle. Thus, if the buckles are mounted
horizontally, one can pull up or down on the handle to release the
buckles in this configuration. The angle of bend of the lever
dictates the angle at which the cables are pulled.
[0015] In yet another embodiment, there is an additional lever
connected to the fulcrum and the handle, and at least one cable and
buckle portion connected to the additional lever. Pulling the
handle pivots both levers and pulls all of the cables connected to
the levers. The two levers can be mounted so that the single
fulcrum is located between the connections of the handle to each of
the levers, so that pulling the handle causes the levers to rotate
in opposite directions. This useful if the some of the cables need
to be pulled up while other cables need to be pulled down in order
to release all of the buckles.
[0016] The levers in this embodiment can be simple straight levers,
triangular shaped, or can be L-shaped and mounted facing away from
each other. With the L-shaped levers, the fulcrum is located at an
elbow of each of the levers. This allows the cables that are
connected to the other arm of the L to be pulled perpendicular to
the direction of pulling of the handle. In this embodiment, the
handle is connected to each of the free ends of the levers that
face away from each other, and the cables are connected to the
other ends of the levers. This works well in a four-buckle system,
so that each lever is connected to two cables, and the system
releases four buckles simultaneously.
[0017] In this system, the fulcrum can be disposed between the
handle and the two cables on each lever, so that both cables on an
individual lever are on the same side of the lever and are moved in
the same direction. Alternatively, the cables can be disposed on
opposite sides of the fulcrum on each lever, so that the individual
cables on each lever move in opposite directions when the handle is
pulled. In this embodiment, two cables are pulled downward, while
the other two are pulled inward, coming from opposite
directions.
[0018] In yet another embodiment, there are two levers as described
above, but each lever has its own fulcrum. Both levers are
connected to a single handle, so that pulling the handle moves both
levers simultaneously around their own fulcrums. In this
embodiment, the levers can be straight or L-shaped. With the
L-shaped lever, the fulcrum is located at an elbow of each
lever.
[0019] Again, the cables can be mounted on the same side of the
lever from the fulcrum or can be disposed on opposite sides from
each other on each lever, depending on the desired direction of
movement of the cables.
[0020] An important use for the system according to the invention
is on a tactical cut-away vest such as used by the military or law
enforcement. Thus, the invention also encompasses a cut-away vest,
comprising:
[0021] (a) a front vest piece having two shoulder sections and two
waist sections;
[0022] (b) a rear vest piece having two shoulder sections and two
waist sections;
[0023] (c) at least two buckle assemblies, each buckle assembly
having a male portion and a female portion, each of the male
portions being attached to one of the front and rear vest pieces at
the shoulder sections and waist sections, and each of the female
portions being attached to the other of the front and rear vest
pieces at the shoulder and waist sections respectively, so that the
front vest piece is connected to the rear vest piece by inserting
each of the male portions into a corresponding female portion;
[0024] (d) a plurality of cables, each cable connected at one end
to one of the male portions; and
[0025] (e) a buckle release system comprising: [0026] (i) a base
plate connected to the vest piece containing the male buckle
portions; [0027] (ii) a fulcrum mounted on the base plate; [0028]
(iii) at least one lever pivotably mounted on the fulcrum, wherein
said cables are connected to the lever at a location remote from
the fulcrum; and [0029] (iv) a handle connected to the lever;
[0030] wherein pulling the handle pivots the lever and pulls the
cables, causing the male buckle portions to release from the female
buckle portions.
[0031] The cut-away vest can be used with any of the variations of
the release systems described above. There can be a single lever,
or two levers, one or two attachment systems, various ways of
mounting the cables and handles, and any number of desired cables.
The system can be configured in any desired orientation to best
accommodate the number and location of buckles on the vest.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0052] Referring now in detail to the drawings and, in particular,
FIGS. 1 and 2 show a cut-away vest 10 having a front section 11 and
a rear section 12. Front section 11 is connected to rear section 12
by a plurality of male buckle portions 13 on front section 11 which
are snapped into a corresponding number of female buckle portions
14 mounted on straps 15 on rear section 12. Each male buckle
portion 13 is connected to a cable 26 slidably disposed within a
cable sheath 16. (Cable 26 is shown in FIG. 3). Underneath patch 17
on front section 11 is a release system 20, which is connected to
all of the cables. Release system 20 is connected to a cable 24
(shown in FIG. 3) surrounded by a cable sheath 22. Cable 24 is
connected to a handle 23. Pulling handle 23 pulls cables 26 and
consequently pulls male buckle portions 13. Male buckle portions 13
are configured such that a sharp pull on male buckle portions 13
causes the side locking legs of male buckle portions 13 to release
from female buckle portions 14, in the manner taught in U.S. patent
application Ser. No. 12/456,609. Thus, pulling on handle 23
releases male buckle portions 13 from female buckle portions 14 to
separate front section 11 from rear section 12, as shown in FIG. 2.
Alternatively, the entire arrangement could be reversed, with the
male buckle portions 13 and the release system 20 mounted on rear
section 12. The user would then reach behind himself/herself to
pull up on handle 23 to free themselves from the vest.
[0053] A first embodiment of release system 20 is shown in FIG. 3.
Release system 20 consists of a base plate 20 onto which a lever 25
is mounted via fulcrum 27. Fulcrum 27 is mounted on one end of
lever 25, and cable 24 is connected to the other end of lever 25.
An attachment assembly 30 is pivotably mounted to lever 25 in
between cable 24 and fulcrum 27. Each of cables 26 are mounted to
attachment assembly 30, and are slidably disposed within cable
sheaths 16. Cable sheaths 16 are disposed within channels 29 on
base plate 21. Pulling upward on handle 23 in the direction of the
arrow causes lever 25 to pivot and pulls all of cables 26 upward as
well. This pulling motion, as explained above, pulls male buckle
portions 13 out of female buckle portions 14.
[0054] An alternative embodiment of the invention is shown in FIGS.
4 and 5. FIG. 4 shows a tactical vest that is similar to the vest
shown in FIGS. 1 and 2, except that the handle is pulled downward
instead of upward to release buckle portions 13. FIG. 5 shows
release assembly 201 that is mounted to the vest 10 in FIG. 4. This
release system is similar to the release system shown in FIG. 3,
except that, fulcrum 27 is mounted in the center of lever 25 with
handle 23 on one side and attachment assembly 30 on the opposite
side of fulcrum 27. Pulling handle 23 downward forces cables 26
upward to release buckle portions 13.
[0055] Another embodiment of the invention is shown in FIGS. 6 and
7. Here, the vest 10 of FIG. 6 is only separated at two places, and
only two buckle assemblies are required. Release system 202 thus is
only connected to two cables 26, but could also be configured to be
connected to several more. Here, release system 202 has a lever 35,
which is configured L-shaped, with lever arm 36 connected to cable
24, lever arm 37 connected to attachment assembly 30, and fulcrum
27 mounted at the elbow of lever 35. While the first embodiment
(shown in FIG. 3) showed the force being transferred in the same
direction of pull on the handle and the second embodiment (shown in
FIG. 5) showed the force in the opposite direction, this embodiment
shows the cables being pulled perpendicular to the direction of
pull on handle 23. Pulling upward on handle 23 causes lever 36 to
pivot around fulcrum 27 and moves cables 26 to the left, in the
direction of the arrow shown. This embodiment is useful if all of
the buckles are located on one side of the object to be released,
such as in the vest of FIG. 6. As shown in FIG. 6, handle 23 can be
mounted up near the shoulder of the vest, which is often a
convenient place for the wear to reach with an opposite hand. The
angle of lever 35 dictates the direction that the pulling force
will be exerted on cables 26. Thus, the lever could be manufactured
to accommodate a pulling force on the cables at any desired angle
to the direction of pull on the handle.
[0056] A further embodiment of the release system according to the
invention is shown in FIGS. 8 and 9. Here, cable 24 with handle 23
is mounted to one end of lever 25, and there are two attachment
assemblies 30, 30'. One attachment assembly 30 is mounted to the
opposite end of lever 35, so that fulcrum 27 is in between handle
23 and attachment assembly 30, and the other attachment assembly
30' is mounted on the same side of lever 25 as handle 23. This way,
pulling up on handle 23 pivots lever 25 and pulls the cables on
attachment assembly 30 downward, and pulls the cables on attachment
assembly 30' upward at the same time. Thus, this embodiment is a
combination of the embodiments shown in FIGS. 3 and 5. This
embodiment is useful if the placement of the buckles requires that
the cables be pulled in opposite directions at the same time in
order to release all of the buckles at once. The vest of FIG. 8
shows the location of cables 16, with some extending from the top
of patch 17, while others extend from the bottom of patch 17.
Pulling on handle 23 releases all four buckle assemblies at once.
This embodiment could also be used with more or fewer buckle
assemblies, depending on the needs of the user.
[0057] Yet another embodiment of the system is shown in FIGS.
10-12. This embodiment can be used on the same vest arrangement
that is shown in FIGS. 1 and 2. Here, release system 204 has two
levers 45, 45' that are triangular in shape, but could also take
other shapes. Each lever 45, 45' is mounted on single fulcrum 27,
which is disposed at one of the corners of each of the triangular
levers. Connected to handle 23 are two cables 24, 24', both
disposed within cable sheath 22. Each of cables 24, 24' are
connected to another corner of lever 45, 45'. Near the third corner
of each of levers 45, 45' are disposed two cables 26, for a total
of four cables, and thus four buckles. Fewer or more cables and
buckles could also be used. Pulling upward on handle 23 causes
levers 45, 45' to rotate in opposite directions (as shown by the
arrows), thus pulling all of cables 26 upward as well, and
releasing all of the buckle assemblies connected to cables 26. As
shown in FIG. 11, levers 45, 45' are mounted on fulcrum 27 in a way
that a portion of lever 45' overlaps a portion of lever 45, with
these portions having a combined height that is equal to the height
of the levers, so that they rest flush in the base plate.
[0058] For all embodiments discussed in this invention, the system
can be equipped with a cover plate 50 that can be mounted on base
plate 20, as shown in FIG. 12. Cover plate 50 can protect release
system 50 against dirt and interference from surrounding
objects.
[0059] Yet another embodiment of the release system according to
the invention is shown in FIGS. 13 and 14. In this system 205,
there are two L-shaped levers 35, 35', each with their own fulcrum
27, 27', respectively. This arrangement is a double version of the
embodiment shown in FIG. 7. Fulcrums 27, 27' are mounted at the
elbow of each of the levers. Cables 24, 24' are connected to a
single handle 23 at one end and are connected to legs 36, 36',
respectively of levers 35, 35'. Cables 26, which are connected to
male buckle portions 14 (not shown in this Figure) are then mounted
to arms 37, 37' of levers 35, 35'. Pulling downward on handle 23
rotates levers 35, 35' in opposite directions from each other,
i.e., lever 35 rotates counter-clockwise, and lever 35' rotates
clockwise. This pulling motion causes cables 26 on arm 37' to be
pulled to the left, and cables 26 on arm 37 to be pulled to the
right. This is a convenient arrangement when there are cables
mounted on opposite sides of the release system, which need to be
pulled in opposite directions in order to be released. As shown in
FIG. 13, the buckles on the right of the vest are released by the
cables being pulled to the left and the buckles on the left of the
vest are released by the cables being pulled to the right, all with
a single downward pull of the handle. Of course, the entire
arrangement could be turned upside down if the user desires an
upward pull on the handle instead.
[0060] Another embodiment of the release system according to the
invention is shown in FIGS. 15 and 16. This system 206 is similar
to the system shown in FIGS. 10 and 11, except that levers 35, 35'
are L-shaped rather than triangular. In this embodiment, both
levers 35, 35' are mounted on a single fulcrum 27, which is located
at the elbow of each of the levers. Two cables 24, 24' are
connected to the ends of each of lever arms 36, 36', which extend
in opposite directions from each other. Cables 26 are then attached
to the ends of each of lever arms 37, 37'. Here, there are two
cables 26 connected to each lever arm 37, 37'. Larger or smaller
numbers of cables and buckles could also be used. Pulling downward
on handle 23 pivots levers 35, 35' so that lever 35 rotates counter
clockwise and lever 35' rotates clockwise. This causes cables 26 on
lever 35' to be pulled to the right, and cables 26 on lever 35 to
be pulled to the left. Thus, as shown in the vest 10 of FIG. 15,
the cables on the right side of the vest are pulled to the left,
and the cables on the left side of the vest are pulled to the
right, all with a single pull of handle 23.
[0061] Yet another embodiment of the release system according to
the invention is shown in FIGS. 17 and 18. Here, release system 207
is almost identical to release system 206, except that one cable 26
is connected to lever arm 37, 37' and another cable 26 is connected
to lever arm 36, 36' of each lever 35, 35'. The cables connected to
lever arms 36, 36' are mounted between cables 24, 24' for handle
23, and fulcrum 27. Thus, pulling handle 23 downward causes the
cables on lever arms 36, 36' to be pulled downward as well, while
the cable on lever arm 37 is pulled to the left, and the cable on
lever arm 37' is pulled to the right. This is an ideal arrangement
for the vest shown in FIG. 17, where two of the buckles are to be
pulled downward, and one buckle is to be pulled to the left, and
one to the right. The system of FIG. 18 makes the angle of the
cable pull coincide with the direction of the buckle release. Thus,
this embodiment eliminates the need for any excess force to release
the buckles when the angle of cable pull does not exactly coincide
with the release direction of the buckles.
[0062] While the embodiments shown in the drawings indicate the
cable being pulled in a direction that is either up or down, any of
the embodiments could be turned upside down to have the handle pull
in the opposite direction. These systems could be used with any
number of buckle assemblies, depending on the needs of the
user.
[0063] Accordingly, while only a few embodiments of the present
invention have been shown and described, it is obvious that many
changes and modifications may be made thereunto without departing
from the spirit and scope of the invention.
