Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention is in the field of supports and specifically rests
for firearms and the like.
2. Description of the Prior Art
Gun rests heretofore used have been subject to criticism for
various reasons including lack of adjustability for height, being
complicated and expensive, of excessive weight and inclined to
movement during use particularly at critical times. Further they
were not easily carried and required considerable time and effort
to render them ready for use as the situation required. Hunters who
use rifles frequently are a considerable distance from the game,
for example 200 or 300 yards, in order to keep from being detected
by sight or smell, and any slight movement of the firearm at such
distance is likely to result in a miss. The hunter may desire to
shoot from any of several positions at different heights and
angles, including while sitting, kneeling, or prone. Accordingly,
there is need for a lightweight rest for a firearm which rest is
conveniently portable, easily used, and easily adjustable to
various heights and angles in a minimum of time.
SUMMARY OF THE INVENTION
The invention includes a post or shaft having a point at one end
and a handle at the other with a step plate and anchor adjacent to
but spaced from the pointed end and which projects in the same
plane as and is parallel to the handle for causing the post to
penetrate the earth. The gun rest is mounted on the post so that it
extends laterally therefrom and is held in adjusted position by an
adjusting screw or thumbscrew. The gun rest has on its lower
portion indicia such as a small projection, for assisting the
hunter in aligning the center of gravity of the rest substantially
in a vertical plane with the point of penetration in order that the
vertical force will have substantially no tendency to cause the
post to tilt in the ground thereby improving stability
notwithstanding the fact that the post is at an angle to a vertical
plane.
It is an object of the invention to provide an adjustable gun rest
of simple inexpensive, lightweight construction which can be easily
carried by the hunter and setup, used and removed with minimum
effort, as well as to provide a gun rest which will facilitate
accurate aim with the use of a gun.
A further object of the invention is to provide an adjustable gun
rest which can be readily installed and adjusted to the desired
height and angularity with the supporting arm directly above the
point of entry of the post in the earth.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 is a side elevation of the invention with the gun rest
rotated substantially 90.degree. to the carrying position.
FIG. 2 is a side elevation illustrating the device in use.
FIG. 3 is a perspective thereof.
FIG. 4 is an enlarged fragmentary detail side elevation.
FIG. 5 is a section on the line 5-5 of FIG. 4.
FIG. 6 is an enlarged detail perspective of the handle.
With further reference to the drawings, the invention includes a
generally tubular post or upright member 10 having a handle 11 at
its upper end and a pointed earth-penetrating extremity 12 at its
lower end. An anchor plate 13 is welded or otherwise attached to
one side of the post 10 adjacent to but spaced a short distance
from the penetrating extremity 12. The anchor plate preferably is
generally triangular in shape and may have an upper edge which
serves as a step for forcing the penetrating extremity into the
earth. As illustrated, the upper portion of the anchor plate may be
bent at substantially right angles to provide a flange or step
plate 14 which likewise may be welded or otherwise attached to the
post 10. The flange or step plate 14 extends outwardly generally
normal to the post 10 and extends laterally from the anchor plate
13 at a slight angle of approximately 12.degree. above a horizontal
plane for a purpose which will be described later.
The handle 11 preferably is of generally tubular construction and
has a major portion 16 disposed on one side of the post 10 and
located generally perpendicular to the axis thereof and generally
parallel to the step plate 14. A minor portion 17 extends from the
opposite side of the post and generally coextensive with the major
portion 16.
In order to support a firearm R, a gun rest 20 is adjustably
mounted on the post 10 between the handle 11 and the step plate 14.
The gun rest incudes a V-way 21 of substantial length adapted to
engage the post 10. The V-way 21 has an outwardly extending portion
22 at one side forming a generally C-shaped portion having a
threaded opening 24 for the reception of a set screw of thumbscrew
25. The set screw 25 is substantially opposite the center of the
V-way 21 so that the inner end of the adjusting screw will engage
the post 10 and force such post against the sides of the V-way 21
to hold the gun rest in fixed adjusted position. It is noted that
if desired a V-shaped clamp could be rotatably mounted on the end
of the adjusting screw so that the post will be clamped between two
V-shaped portions.
Projecting outwardly from the V-way 21 on the side remote from the
C-shaped portion, is a generally semicircular support arm 30.
Preferably the outer portion of the support arm is generally round
in cross section to produce identical placement of a portion of the
rifle through full rotation ranges and forearm adjustments. The
outer free end 31 of the support arm terminates slightly below the
plane of the top of the V-way so that a line 32 (FIG. 4) from the
top of the V-way to the outer end 31 is at a slight angle of
substantially 12.degree. for a purpose which will be described
later. A button or projection 33 is located on the bottom of the
support arm 30 substantially at the center thereof or approximately
at the center of gravity thereof. As indicated in FIG. 4, it will
be apparent that a radial line 34 drawn from the center 35 of the
semicircle to the center of the button 33 will be disposed at an
angle to the axis of the post 10.
In order to facilitate the use of the device a dot, button or other
indicia 36 (FIG. 3) is placed on the post at the level of the step
plate 14 and on the side of the post from which the support arm 30
extends.
While various lengths of post may be employed, a post which permits
an adjustment in height of the rest through a range of
approximately 27 inches permits it to be used for prone, kneeling,
and sitting use for most hunters.
Various materials may be used for the construction of the device.
The post 10 and handle 11 preferably are constructed of steel or
aluminum tubing with an appropriate finish to avoid corrosion. A
baked wrinkle finish for steel posts is particularly desirable for
maximum durability, ease in gripping, and low-light reflection and
an anodized finish, which may be of any desired color, is desirable
for an aluminum post. The gun rest 20 preferably is constructed of
cast manganese bronze or aluminum of high tensile strength and
preferably has a resilient sleeve 37 of a material such as
polyvinyl chloride to cushion and protect the finish of the
firearm. The thumbscrew preferably is made of brass or aluminum
with a wing having a dull finish.
To facilitate use of the device indicia such as crossed long and
short arrows 38 and 39, respectively, may be placed on the
handle.
In the use of the device the hunter may carry the rest like a cane
until he reaches a position of use. As he faces toward the target,
the handle 11 and anchor plate 13 are held so that they are
substantially in line with the line to the target. Then, the hunter
adjusts the rest to the height which he desires, with the rest
projecting at substantially right angles to the line of sight and
to the right of the post. If he is referring to the indicia arrows
38 and 39 on the handle, the long arrow 38 points toward the target
and the short arrow 39 in the line along which the gun rest
extends. With the rest adjusted at the proper height and
maintaining the line of the handle along the line of sight the
hunter then holds the rod at such an angle that a plumb line 40
(FIG. 2) from the button 33 on the lower side of the support arm
would intersect the dot or button 36 adjacent to the step plate.
Then, he uses his foot against the step plate at the same time he
presses down on the handle in order to push the rod into the ground
at such angularly disposed position. The rod is pushed into the
ground until the step plate is pressed flat and tight against it.
The rest is then ready to use.
It will be apparent that with the rest in place as described, the
weight of the firearm acts in substantially a direct line with the
intersection of the rod and the ground and, therefore, the moment
tending to rotate the rod in the ground is substantially zero.
Accordingly, the tendency to move the rod or to cause it to sway is
substantially avoided. Also, the anchor plate 13 extends flatwise
to any tendency of the rod to move and, therefore, is well anchored
against such movement. Further, the step plate being engaged firmly
with the surface of the ground likewise resists any tendency of the
rod to move. Hence, with only a small penetration of the rod, a
very stable rest is provided.
The semicircular support arm is arranged so that when the gun rest
20 is positioned approximately midway of the rod, the radial line
34 coincides with the plumb line 40 and the line 32 from the top of
the V-way to the outer free end 31 of the support arm will be
horizontal as indicated in FIG. 2. At other positions, the line 32
approaches but is slightly off the horizontal. Since the firearm is
placed in the support arm and the post is tilted away from the
firearm, the tendency of the post to interfere with vision along
the line of sight is reduced.
While the rest is adapted for heavy rifles with high powered
scopes, it also can be used advantageously for lighter rifles and
for hand guns. In addition to being useful for hunting of animals
such as woodchucks, crows, foxes, wolves, antelopes, turkeys or
deer, where precise bullet placement is essential, it may also be
used for sighting in, target work, and as a "bench rest" under
field conditions.
