Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to a bipod rifle support and more
particularly to a bipod rifle support which may be either attached
to a rifle stock or wherein the rifle stock may be modified to
accept the bipod support.
[0003] 2. Description of the Related Art
[0004] Bipod rifle supports have long been used to support the
forward end or muzzle of a rifle during the firing thereof in an
effort to "steady" or "stabilize" the rifle to increase the
shooter's accuracy. The bipod rifle supports are also useful to
support the muzzle of the rifle above the ground or other
supporting surface during periods when the rifle is not being fired
or is being cleaned.
[0005] Many types of bipod rifle supports have been previously
provided but it is believed they suffer from certain disadvantages.
Certain of the prior art bipod rifle supports are large,
cumbersome, difficult to use and detract from the appearance of the
rifle.
SUMMARY OF THE INVENTION
[0006] The bipod rifle support of this invention is illustrated
herein in two different forms. In one embodiment, the bipod rifle
support is contained within an elongated body member which is
attached to the underside of the fore-end of the rifle stock. In
the second embodiment, the rifle stock is modified so as to accept
the bipod rifle support of this invention.
[0007] In the embodiment wherein the bipod rifle support is secured
to the underside of the fore-end of the rifle stock, the support
includes an elongated body member having a forward end, a rearward
end, a first side, a second side, an upper surface and a lower
surface. The body member is selectively removably attachable to the
stock at the fore-end thereof. First and second horizontally
spaced-apart elongated bores are formed in the body member which
have forward ends exiting from the forward end of the body member
and which have rearward ends positioned adjacent the rearward end
of the body member. A third bore, having upper and lower ends, is
formed in the body member adjacent the forward end thereof adjacent
one side thereof which extends upwardly into the body member from
the lower surface thereof with the upper end of the third bore
communicating with the first bore, rearwardly of the forward end
thereof. A fourth bore, having upper and lower ends, is formed in
the body member adjacent the forward end thereof adjacent the other
side thereof which extends upwardly into the body member from the
lower surface thereof with the upper end of the fourth bore
communicating with the second bore rearwardly of the forward end
thereof. A first slot is formed in the body member which extends
forwardly from the third bore for the entire length thereof to the
forward end of the first bore. A second slot is formed in the body
member which extends forwardly from the fourth bore for the entire
length thereof to the forward end of the second bore.
[0008] First and second elongated elastic cords are also included
which have forward and rearward ends. The rearward end of the first
elastic cord is secured to the body member adjacent the rearward
end thereof with the first elastic cord extending forwardly from
its rearward end through the first bore. The rearward end of the
second elastic cord is secured to the body member adjacent the
rearward end thereof and extends forwardly therefrom through the
second bore. First and second elongated support legs having first
and second ends are also provided. The first and second support
legs are sized so as to be selectively received by the first and
second bores respectively. The forward ends of the first and second
elastic cords are secured to the first and second support legs
respectively.
[0009] The first and second support legs are selectively movable
between a stowed position within the first and second bores
respectively to a rifle support position wherein the first ends of
the first and second support legs are positioned in the third and
fourth bores respectively. The first and second slots permit the
first and second elastic cords to pass therethrough as the support
legs are moved from their stowed position to their rifle support
positions and vice versa. The connection of the elastic cords to
the support legs causes the support legs to be yieldably maintained
in their stowed and rifle support positions.
[0010] In the preferred embodiment, the third and fourth bores
extend upwardly, laterally and forwardly into the body member from
the lower surface thereof. In the second embodiment of the
invention, the body member is not utilized with the rifle stock
having the first, second, third and fourth bores formed therein and
having the first and second slots formed therein.
[0011] It is therefore a principal object of the invention to
provide an improved bipod rifle support.
[0012] Still another object of the invention is to provide an
improved bipod rifle support which may be either contained within a
body member which is attachable to the underside of the fore-end of
the rifle stock or which may be incorporated into the rifle stock
itself.
[0013] Still another object of the invention is to provide a bipod
rifle support which is aesthetic in appearance.
[0014] Still another object of the invention is to provide a bipod
rifle support which is easily attachable to the underside of the
fore-end of a rifle stock.
[0015] Still another object of the invention is to provide a bipod
rifle support which is positioned in the rifle stock itself which
may be removed therefrom to support the rifle stock.
[0016] Still another object of the invention is to provide a bipod
rifle support which enables the rifle to be supported during the
firing thereof or which may be used to support the rifle during
periods of non-use.
[0017] Still another object of the invention is to provide a bipod
rifle support which is economical of manufacture, durable in use
and refined in appearance.
[0018] These and other objects will be apparent to those skilled in
the art.

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0028] In the drawings, the numeral 10 refers to a rifle of
conventional design including a stock 12 having a butt portion 14
and a fore-end 16. As stated hereinabove, the bipod rifle support
of this invention may be incorporated into the forward end of the
rifle stock 12 as seen in FIG. 9, or may be incorporated into an
elongated body member 18 which is selectively removably secured to
the underside of the fore-end 16 of the stock 12 as seen in FIGS.
1-8. In most cases, the stock 12 will have an internally threaded
opening 20 formed in the underside of the stock 12 (FIG. 2) to
which is normally attached a sling stud 21. Body member 18 is
removably secured to stock 12 by the sling screw 21.
[0029] For purposes of description, body member 18 will be
described as having a forward end 22, rearward end 24, an upper
surface 26 and a lower surface 28. Preferably, the body member 18
will be comprised of the same material as the stock. For example,
if the stock 12 is comprised of a wood material, the body member 18
will normally be comprised of a wood material. If the stock 12 is
comprised of a composite material, the body member 18 will also be
comprised of a composite material. Body member 18 also includes a
first side 30 and a second side 32.
[0030] The body member 18 has first and second horizontally
spaced-apart elongated bores 34 and 36 formed therein (FIG. 3)
which have forward ends exiting from the forward end of the body
member 18 and which have rearward ends positioned adjacent the
rearward end of the body member 18 as seen in FIG. 7.
[0031] Body member 18 also has a third bore or socket 38 having
upper and lower ends, formed therein adjacent the forward end
thereof which extends upwardly into the body member 18 from the
lower surface 28 with the upper end of the third bore 38
communicating with the first bore 34 rearwardly of the forward end
thereof. Preferably, the third bore 38 extends upwardly, laterally
and forwardly into the body member 18 from the lower surface 28
thereof. The body member 18 also has a fourth bore or socket 40,
having upper and lower ends, formed therein adjacent the forward
end thereof which preferably extends upwardly, laterally and
forwardly into the body member 18 from the lower surface 28
thereof. The upper end of bore 40 communicates with the second bore
36 rearwardly of the forward end thereof.
[0032] Body member 18 also has a first slot 42 formed therein which
extends forwardly from the third bore 38 for the entire length
thereof to the forward end of the first bore 34. The body member 18
also has a second slot 44 formed therein which extends forwardly
from the fourth bore 40 for the entire length thereof to the
forward end of the second bore 36.
[0033] The numerals 44 and 46 refer to first and second elongated
elastic cords which have forward and rearward ends. The rearward
end of the first elastic cord 44 is secured to the body member
adjacent the rearward end thereof. The first elastic cord 44
extends forwardly from its rearward end through the first bore 34.
The rearward end of the second elastic cord 46 is secured to the
body member 18 adjacent the rearward end thereof and extends
forwardly therefrom through the second bore 36. Rubber shock
absorbers 49 and 51 are slidably mounted on the cords 44 and 46 as
seen in FIG. 3 to cushion the impact of the legs associated
therewith as will be explained in more detail hereinafter.
[0034] The numeral 48 refers to a first elongated support leg
having a first end 50 and a second end 52. The numeral 54 refers to
a second elongated support leg having a first end 56 and a second
end 58. The first and second support legs 48 and 54 are sized so as
to be selectively received by the first and second bores 34 and 36
respectively.
[0035] The first and second support legs 48 and 54 are selectively
movable between a stowed position within the first and second bores
34 and 36 respectively (FIG. 2) to a rifle support position as seen
in FIGS. 1 and 8 wherein the first ends of the support legs 48 and
54 are positioned in the third and fourth bores 38 and 40
respectively. The first and second slots 42 and 44 permit the first
and second elastic cords 44 and 46 to pass therethrough as the
support legs 48 and 54 are moved from their stowed position to
their rifle support positions and vice versa.
[0036] In the second embodiment of this invention illustrated in
FIG. 9, the body member 18 is eliminated with the bores 34, 36, 38
and 40 and the slots 42 and 44 being formed in the fore-end or the
forward end of the rifle stock respectively. The bores and the
slots may either be created in the rifle stock at the factory or a
suitable gun shop. In either case, the second ends of the support
legs 48 and 54 have enlarged resilient foot portions 56 and 58
secured thereto to prevent the support legs 48 and 54 from slipping
on the supporting surface or for damaging the supporting surface
should the rifle be placed on a table or bench.
[0037] It can be seen from the foregoing that a novel bipod rifle
support has been provided which may be included in a body member 18
which is attachable to the rifle stock or which may be incorporated
into the stock itself. The bipod rifle support of this invention is
extremely durable in use and is refined in appearance and does not
detract from the aesthetic appearance of the rifle stock which is
important to many riflemen.
[0038] Although it has been shown that the elastic cords 44 and 46
are utilized, the elastic cords 44 and 46 could be non-elastic as
long as a spring is connected thereto to yieldably urge the support
legs 48 and 54 rearwardly into the bores 34 and 36 as well as to
yieldably urge the support legs 48 and 54 into the bores 38 and
40.
[0039] Thus it can be seen that the invention accomplishes at least
all of its stated objectives.
