Wrist braced slingshot
Abstract
A slingshot having a pistol grip type handle for grip having a
yoke or crotch with flexible members attached to the arms of the
yoke and to a pad or holder for a missile or projectile. Extending
from the bottom of the pistol grip is a brace which extends
rearwardly and has a curved part that fits over the arm or wrist of
the user so as to securely brace and stabilize the slingshot in
use. The brace is spring held and adjustable within the handle
between positions, one of which allows pivotal aiming adjustment of
the pistol grip relative to the brace. The brace may be
frictionally held within the handle, thus preventing rotation of
the handle with respect to the brace.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to the slingshot art and more particularly
to an improved slingshot having a wrist brace.
2. Description of the Prior Art
Typical slingshots have long been known and the average youth
having at some time in his life built one himself, usually using a
crotch cut from a branch of a tree and using rubber bands formed as
strips from old innertubes. However, such prior art slingshots did
not provide a wrist brace to insure greater accuracy in the use
thereof. In other prior art slingshots, if a wrist brace were
provided, it was neither adjustable nor removable.
SUMMARY OF THE INVENTION
This invention is an improved form of slingshot of the type adapted
for ease of fabrication and commercial production.
Basically the invention embodies a hand grip, preferably in the
form of a pistol grip, from which extends a yoke or a crotch to
which are attached the flexible members which preferably are rubber
tubular members at the ends of which are attached the pad holder or
pouch which holds the missile or projectile.
A particular and unique improvement in the invention is that a
wrist or arm brace is provided in the form of a rod detachably
mountable by frictional retention securement means on the hand grip
and extending from the lower end of the pistol grip of the
slingshot. This wrist brace rod extends rearwardly and has a curved
part which fits over the arm or wrist of the user. The brace which
engages firmly on the top of the wrist stabilizes the slingshot and
enables the user to hold it firmly and steadily and thereby aim and
discharge the missile or projectile more accurately. In one
embodiment the support brace is adjustable between two positions
and in one of which the pistol grip is free for limited lateral
rotation relative to the wrist brace to provide for additional
aiming capabilities, and in the other provides rigid bracing. The
slingshot thereby becomes a significant and dependable weapon for
use in hunting or target shooting.
A primary object is to make possible and to realize firmer and more
stable holding of the hand grip of the slingshot and to relieve the
amount of tension exerted on the hand by way of the above-described
brace which extends rearwardly and fits over the wrist or arm thus
restraining rearward pull on the yoke or crotch of the
slingshot.
In a preferred exemplary form of the invention as described in
detail herein, the hand grip is preferably formed as a pistol grip
type adapted for easy and firm holding. Preferably the grip is
formed from plastic in sections adapted for fabrication by
injection molding processes the two sections being held together,
for example, by screws. Preferably the wrist brace is detachable
from the slingshot for convenience in storing and transporting by
the user and is formed from a metal rod with an end part extending
into the bottom of the pistol grip with a spring detent means to
establish its two adjustable positions in one of which the hand
grip is free for limited lateral rotation for aiming. Further
objects reside in the realization of the simplified form of pistol
type grip and simplified holding means for holding the wrist brace
in its two positions, and for removal of the wrist brace in those
embodiments where adjustable positions thereof are not
utilized.

Referring now more in detail to the drawings and particularly FIG.
1, the pistol grip handle is shown at 10. The yoke or crotch is
designated by the numeral 12. The wrist brace is designated by the
numeral 14. The yoke has two arms as shown having rearwardly
extending parts 16 and 18 to which are attached flexible members
which, in the preferred form of the invention, are rubber tubes as
designated at 20 and 22. The ends of these tubes are attached to a
leather pouch 26 which holds the missile or projectile.
The yoke or crotch 12 is shown in detail in FIGS. 2 and 3. In the
preferred form of the invention it comprises two rod pieces 30 and
32 bent as shown and welded or soldered together at points, two of
which are designated at 34. Numeral 36 designates a hole through
the stems of the two pieces for attachment of the pistol grip by
way of a screw in the pistol grip. Preferably the tubular members
20 and 22 may be attached to the extending ends 16 and 18 simply by
being tightly fitted over them. The pouch 26 is preferably attached
to the tubular members 20 and 22 by plastic webs 40 and 42 which
pass through slits or openings in the pouch 26 with the ends of
these webs welded together and provided with enlarging ribs which
tightly fit into the tubular members 20 and 22.
The wrist brace 14 is shown in detail in FIG. 4 and is detachably
insertable in the pistol grip 10 as described below. It is formed
preferably of a metal having a part 46 that extends up into the
bottom of the pistol grip 10. The end of this part being flattened
as shown at 47 and having two side detent notches 48 and 49 which
will be referred to again presently. The brace 14 has a
transversely extending part 51 and a portion 52 that extends
rearwardly in a position adjacent to the wrist and at the end of
this spot is a curved or looped part 53 positioned to fit over the
top of the arm or wrist and preferably this curved part has fitted
over it a piece of soft cushioning tubular material 54 so that it
will be comfortable on the wrist.
The pistol grip 10 is preferably formed in sections by plastic
injection molding process. The two sections are secured together by
screws. FIGS. 5 and 6 show the front half or section 60 which is
configurated and shown at 61 to fit or conform to the fingers of
the user. As may be seen it is rounded at the top and bottom as
designated at 62 and 63 and the sides are concavely bowed inwardly
as may be seen in FIG. 6. As may be seen in the interior view of
FIG. 6 there are vertical webs 64, 65 and 66. There are transverse
webs 67, 68 and 69. Numerals 70 and 71 designate screw holes
whereby the front and rear sections are secured together as will be
described. Numeral 74 designates a slot or groove in the transverse
web 68. Numeral 75 designates an aligned groove in a short
transverse web 76. These grooves meet with similar grooves in the
rear half section as will be described and are adapted to receive
in one of two positions the end part 46 and flattened portion 47 of
the wrist brace 14.
FIGS. 12 and 13 show a flat metal detent spring 80 having a right
angle part 81 and a detent bend 82 at one end. This spring normally
occupies a position as shown in FIG. 6. Its end with the flange or
bend part 81 fitting between the screw in screw hole 71 and a
vertical web part 83 there being a mutually cooperating part in the
rear section of the hand grip as will be described which cooperate
in holding the detent spring 80, the bend end part or detent part
82 of which cooperates with the notches 48 and 49 in the end 46 of
the wrist brace 14 as will be described.
FIGS. 7 and 8 show the rear half or section of the pistol grip this
part being designated at 90. It is convexly curved rearwardly as
designated at 91 and is curved at the top and bottom as designated
at 92 and 93. FIG. 8 is an interior view of the rear section. FIGS.
9, 10 and 11 are cross-sectional views at the levels indicated by
the section lines in FIG. 8. This section has a vertical web 96 and
lower vertical web 97. It has transverse webs 97, 98, 99 and 100
the webs being positioned to be juxtaposed against, that is, to
cooperate with the corresponding webs previously described in the
front section 60. Numerals 101 and 102 designate screw holes that
line or register with the screw holes 70 and 71 of the front half
to receive small bolts that go through these holes and receive
small nuts that fit into countersinks or courterbores 103 and 104
in the front section as may be seen in FIG. 5. The bores 101 and
102 have similar counterbores as designated at 107 and 108 to
receive the heads of the screws that hold the two sections
together. It will be appreciated that self tapping screws, rivets
or other similar means may be utilized in place of the nuts and
bolts.
Numeral 112 designates a slot in a part of the web 98 which
corresponds to the slot 74 of FIG. 6, these slots being juxtaposed
together when the parts are assembled. Numeral 113 designates a
similar aligned slot in the web 99 which corresponds to and is
juxtaposed with respect to the slot 75 of FIG. 6 so that aligned
slot openings are provided as previously described to receive the
end 46 of the wrist brace 14 the detent bend 82 at the end of the
detent spring 80 cooperating with one of the notches 48 or 49 of
the end part 46 of the wrist brace 14. In the upper adjusted
position of the wrist brace the flattened end 47 is received and
frictionally retained in a correspondingly shaped opening formed by
the juxtaposed slots 112 and 74 in the rear and front sections of
the end grip and when received in this slot the end grip cannot be
rotated laterally relative to the wrist brace but is held firmly.
In the upper position of the detent bend 82 spring 80 is in the
notch 49. In the lower position of the wrist brace the detent bend
82 on spring 80 is in the upper notch 48 in the end part 46 of the
wrist brace 14. In the lower position the flattened end 47 is not
in the slot-like hole or opening 112 and 74 provided for it and in
this position the hand grip 10 can be rotated laterally a limited
amount relative to the wrist brace for purposes of accommodating
more perfect aiming.
FIG. 14 illustrates another embodiment of a wrist brace, generally
designated 120, useful in the practice of the present invention.
The wrist brace 120 is generally similar to the wrist brace 14
shown in FIG. 4 except that the detent notches 48 and 49 are
omitted. The flattened end portion 122 is identical to the
flattened end portion 47 of the embodiment 14.
The wrist brace 120 is detachably insertable in and may be utilized
with the structure described above, the flattened end portion 122
being received in the slot-like openings 112 and 74 for frictional
retention therein. Thus, the wrist brace embodiment 120 does not
provide the two position feature of the embodiment 14 but only the
single position corresponding to the upper adjusted position. The
spring 80 may be omitted if desired when utilizing the wrist brace
120.
Thus, both the wrist brace 14 and wrist brace 120 are detachably
insertable and removable so that, when desired, such as for
storing, transporting, etc., the wrist brace may be removed to
provide a more compact arrangement.
From the foregoing those skilled in the art will readily understand
the nature and construction of the invention and the manner in
which it realizes and achieves all of the objects as set forth in
the foregoing. The slingshot is used like the regular known
slingshot but the unique improved features provided by way of the
detachably mountable wrist brace which, as described, fits over the
wrist to stabilize the instrument for more perfect holding and
aiming and for relieving the force on the hand holding the hand
grip; that is, the force exerted by the flexible members on the
yolk or crotch.
The foregoing disclosure is representative of preferred forms of
the invention and is to be interpreted in an illustrative rather
than a limiting sense, the invention to be accorded the full scope
of the claims appended hereto.
