The top assembly has base plate, a right-side rail assembly has a first support pad, and a left-side rail assembly has a second support pad. The first support pad contacts the forearm of the rifle below an equator of the forearm, and the second support pad contacts the forearm of the rifle above the equator in a way that the contact points counteract radial torque applied to the rifle upon firing.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to the provisional patent application identified by U.S. Ser. No. 63/598,251, filed Nov. 13, 2023, the entire content of which is hereby expressly incorporated herein by reference.

BACKGROUND

Rifles used in competitive long-distance range shooting are generally supported by a front rifle rest and a rear support in the form of a sandbag. The most commonly used front rests are tripod stands supporting a sandbag or vise to hold the rifle. The legs and other parts of the rest have mechanical adjustments to position and aim the rifle.
Accuracy and precision while shooting long-range are hindered by many variables. These variables affect both short-range shooting and long-range shooting. However, at longer ranges the effect is much more noticeable. Wind, mirage, etc., are environmental in nature and cannot be overcome by technology. However, there are several physical properties involved that can be addressed by technique and or equipment. Gunstock design, rear sandbag design, and front rest design all have an effect on accuracy and precision.
First, when a bullet is fired, there is the acceleration of a bullet down the barrel that creates a mathematically defined force or reaction based on the weight of the bullet opposing the gun weight, the net of which is called recoil. This is linear recoil and it can be reduced in several ways. Over the years, there have been all sorts of recoil reducers designed and built utilizing air, springs, hydraulics, and simply adding weight or mass to the rifle.
Second, a less understood form of recoil is observed as the twisting or torquing of the rifle when a bullet is fired. All rifle barrels have grooves or rifling to impart a right-hand or clockwise spin on the bullet for stability. The longer and heavier the bullet, the more spin it requires to stabilize, thus generating more radial recoil. Again, this clockwise bullet spin generates an equal but opposite reaction. This opposite reaction is commonly referred to as torque but is also known as radial recoil.
Until now, the problems caused by radial recoil have not been addressed directly by any front rest. However, the symptoms of radial recoil have been managed in several other ways. One way to decrease the effect of torque is by lowering the rifle barrel in the forearm of the rifle stock. This method puts the source of torque lower and between the sandbags instead of above the sandbags. Another popular attempt at managing torque is to make the vertical sides of the rifle forearm taller, thereby increasing the contact patch of the front sandbags. These both work to some degree and have become popular in long-range equipment.
Another way of mitigating the effect of radial recoil is by altering the materials used on the vertical sides of the front rests. Varying degrees of effectiveness have been seen by modifying the hardness or fill of the front sandbags, using different materials, and using hard rollers.
In all methods discussed above, the contact point holding the forearm is in contact at roughly the three and nine o'clock positions on the forearm. This arrangement allows the forearm to roll to the left or counterclockwise about the centers of the bags or pads to lesser or greater amounts.
With all current methods discussed, the tension of the front bags or pads is being relied on to limit the radial movement but this is creating another problem in terms of friction in the linear plane. High friction or tracking force will cause vertical shot dispersion and, in the extreme, is illegal by rule. The high-power competition rules state that the rifle must be free to be picked up from the rest.

This description should be read to include one or at least one and the singular also includes the plural unless it is obvious that it is meant otherwise.
Referring now to the figures, and more particularly to FIGS. 1-3 , a front rifle rest 10 is shown. The rifle rest 10 is configured to support a forearm or stock 12 of a rifle 14 (FIGS. 7 and 8 ) while a user is aiming and firing the rifle 14 at a target. The rifle rest 10 generally includes a base 16 and a top assembly 18.
The base 16 may have a bipod or tripod configuration wherein the base 16 has two or three legs (not shown) for engaging a surface such as the ground. The legs may be vertically adjustable. It will be appreciated by those of ordinary skill in the art that the base 16 may be constructed in various forms without departing from the scope of the inventive concepts disclosed herein.
The top assembly 18 is connected to the base 16 and configured to cradle the forearm 12 of the rifle 14. In one embodiment, the top assembly 18 has a bridge 20 and a base plate 22. The base plate 22 is rotatable relative to the bridge 20 about a vertical axis, and the base plate 22 is selectively movable along a vertical plane. These movements together enable the base plate 20 to be movable for adjusting a horizontal aim of the rifle 14 for adjusting a vertical aim of the rifle 14.
The base plate 22 has an upper side to which a right-side rail assembly 24 a and a left-side rail assembly 24 b are mounted. The side rail assemblies 24 a and 24 b form the cradle for the forearm 12 of the rifle 14. A forearm stop 26 may also extend from a front side of the base plate 22 in a manner well-known in the art.
The right-side rail assembly 24 a includes a block 30 a, a bottom support pad assembly 32 a, and a side support pad assembly 34 a, and the left-side rail assembly 24 b includes a block 30 b, a bottom support pad assembly 32 b, and a side support pad assembly 34 b. The right-side rail assembly 24 a and the left-side rail assembly 24 b are adjustable along the base plate 22 in a to-and-fro manner relative to one another to slidably secure the forearm 12 of the rifle 14 between the right-side rail assembly 24 a and left-side rail assembly 24 b. The right-side rail assembly 24 a and the left-side rail assembly 24 b may be adjustable to accommodate various forearm widths, such as from less than two inches to over five inches in width.
The block 30 a has an inward-facing surface 36 a. The block 30 a may have a shoulder 38 a near a lower end thereof. The inward-facing surface 36 a may be angled outwardly from the shoulder 38 a relative to a vertical plane at an angle 39 a of approximately two degrees (FIG. 2B). But in another version, the inward-facing surface 36 a may be vertical.
The block 30 b has an inward-facing surface 36 b. The block 30 b may have a shoulder 38 b near a lower end thereof. The inward-facing surface 36 b may be angled inward from the shoulder 36 b relative to a vertical plane at an angle 39 b of approximately two degrees so the inward-facing surface 36 b of the block 30 b is parallel to the inward-facing surface 36 a of the block 30 a (FIG. 2B). But in another version, the inward-facing surface 36 b may be vertical to correspond to the inward-facing surface 36 a of the block 30 a in a parallel fashion.
The bottom support pad assembly 32 a may include a support member 38 a (e.g., a block) and a support pad 40 a mounted to an upper side of the support member 38 a so the support pad 40 a forms a portion of a forearm support. The support member 38 a is connected to the block 30 a with a fastener 42, so the support member 38 a and the support pad 40 a are rotatable front to back about a horizontal axis.
The bottom support pad assembly 32 b may include a support member 38 b (e.g., a block) and a support pad 40 b mounted to an upper side of the support member 38 b, so the support pad 40 b forms a portion of a forearm support. The support member 38 b is connected to the block 30 b with a fastener 42, so the support member 38 b and the support pad 40 b are rotatable front to back about the horizontal axis, which the support member 38 a and the support pad 40 a are rotatable. Together, the bottom support pad assembly 32 a and the bottom support pad assembly 32 b form a support for a lower side of the forearm 12 of the rifle 14 across which the forearm 12 may slide when the rifle 14 experiences linear recoil upon firing.
The side support pad assembly 34 a (FIG. 4 ) may include a support member 44 a (e.g., a plate) and a support pad 46 a mounted on one side of the support member 44 a so the support pad 46 a forms a portion of a support. The support pad 44 a may be mounted adjacent to a lengthwise edge of the support member 44 a. The support member 44 a is connected to the inward-facing surface 36 a of the block 30 a with suitable fasteners 48, so the support member 44 a and the support pad 46 a are fixed in position. The support member 44 a may be provided with a pair of slots 50 so the vertical position of the side support pad assembly 34 a relative to the block 30 a is adjustable.
The side support pad assembly 34 b (FIG. 4 ) may be identical in construction to the side support pad assembly 34 a. To this end, the side support pad assembly 34 b may include a support member 44 b (e.g., a plate) and a support pad 46 b mounted on one side of the support member 44 b, so the support pad 44 b forms a portion of a support. The support member 44 b is connected to the inward-facing surface 36 b of the block 30 b with suitable fasteners 48 so the support member 44 b and the support pad 46 b are fixed in position. The support member 44 b may be provided with a pair of slots 50 so the vertical position of the side support pad assembly 34 b relative to the block 30 b is adjustable.
In one embodiment, the support pads 40 a, 40 b, 46 a, and 46 b may be sandbags with a tube or bag filled with a particulate material. The bag may vary in size and the materials used to manufacture the bag. Regardless, the sandbags should be deformable by finger pressure when filled with the particulate material. In one exemplary embodiment, the sandbags 40 a and 40 b have a length of 1½″ inches and a diameter of ⅜″ inches, and the sandbags 46 a and 46 b have a length of 2½″ inches and a diameter of ⅜″ inches. An exemplary material used for the bag is a braided nylon, and an exemplary particulate material is 100-150 grit glass beads.
Referring to FIGS. 7 and 8 , in use, the side support pad assembly 34 a is mounted to the block 30 a so the support pad 46 a contacts the forearm 12 of the rifle 14 solely below the equator of the forearm 12, and the side support pad assembly 34 b is mounted to the block 30 b so the support pad 46 b is vertically staggered relative to the support pad 46 a and contacts the forearm 12 of the rifle 14 solely above the equator of the forearm 12. Such contact counteracts the counterclockwise (as viewed from the rear of the rifle 14) radial torque applied to the rifle 14 upon the rifle 14 being fired.
In one embodiment, the side support pad assembly 34 a is mounted to the block 30 a so the support pad 46 a contacts the forearm 12 of the rifle 14 near a lowest area of the forearm 12, and the side support pad assembly 34 b is mounted to the block 30 b so the support pad 46 b contacts the forearm 12 of the rifle 14 approximate a highest area of the forearm 12. Again, such contact counteracts the counterclockwise (as viewed from the rear of the rifle 14) radial torque applied to the rifle 14 upon the rifle 14 being fired.
Referring now to FIGS. 9-13 , another embodiment of a right-side rail assembly 50 a and a left-side rail assembly 50 b is illustrated. The right-side rail assembly 50 a and the left-side rail assembly 50 b are similar in construction to the right-side rail assembly 24 a and the left-side rail assembly 24, respectively, except as described below.
With the right-side rail assembly 50 a, the side support pad assembly 34 a is a sheet of material 52 a, such as a felt. The sheet of material 52 a is adhered to the inward-facing surface 36 a of the block 30 a. The sheet of material 52 a is substantially planar, so the sheet of material 52 a is angled outwardly from the shoulder 38 a relative to a vertical plane at an angle 53 a of approximately two degrees (FIG. 9B).
With the left side rail assembly 50 b, the side support pad assembly 34 b is a sheet of material 52 b, such as a felt. The sheet of material 52 b is adhered to the inward-facing surface 36 b of the block 30 b. The sheet of material 52 b is substantially planar, so the sheet of material 52 b is angled inwardly from the shoulder 38 b relative to a vertical plane at an angle 53 b of approximately two degrees (FIG. 9B).
With reference to FIGS. 10 and 11 , in use, the sheet of material 52 a is mounted to the block 30 a so the sheet of material 52 a contacts the forearm 12 of the rifle 14 solely below the equator of the forearm 12, and the sheet of material 52 b is mounted to the block 30 b so the sheet of material 52 b contacts the forearm 12 of the rifle 14 solely above the equator of the forearm 12 of the firearm. Such contact counteracts the counterclockwise (as viewed from the rear of the rifle 14) radial torque applied to the rifle 14 upon the rifle 14 being fired.
From the above description, it is clear that the inventive concepts disclosed and claimed herein are well adapted to carry out the objects and to attain the advantages mentioned herein, as well as those inherent in the invention. While exemplary embodiments of the inventive concepts have been described for purposes of this disclosure, it will be understood that numerous changes may be made that will readily suggest themselves to those skilled in the art and which are accomplished within the spirit of the inventive concepts disclosed.
