FIELD
The present disclosure generally relates to firearm accessories, and more particularly to rests for firearms.
BACKGROUND
Various types of firearm rests are known. Shooting rests are used to support part or all of the weight of a firearm to assist a user in shooting the firearm. Shooting rests enable shooters to aim a firearm more steadily at a target and thus improve shooting accuracy.
SUMMARY
In one aspect, a shooting rest is for supporting a firearm including a trigger, a trigger hand grip portion adjacent the trigger, a butt portion rearward from the trigger hand grip portion, and a forward portion forward from the trigger hand grip portion. The shooting rest includes a frame, a forward support, and a rear support. The forward support is supported by the frame and includes a cradle configured to receive the forward portion of the firearm. The cradle is pivotable with respect to the frame to adjust an aim of the firearm. A rearward support is supported by the frame and includes a platform positioned to engage a bottom of the hand grip portion of the firearm to support the hand grip portion.
In another aspect, a shooting rest is for supporting a firearm including a trigger and a forward portion forward of the trigger. The shooting rest includes a frame and a cradle. The cradle is supported by the frame to support the forward portion of the firearm. The cradle includes first and second jaws and a bed between the jaws. The first and second jaws are movable with respect to the bed to clamp the forward portion of the firearm between the jaws. The cradle includes an actuator operatively connected to the first and second jaws. The actuator is operable to move the first and second jaws toward each other at the same time at the same rate of movement.
Other objects and features of the present disclosure will be in part apparent and in part pointed out herein.

DETAILED DESCRIPTION
Referring to FIGS. 1-3, a firearm shooting rest is designated generally by the reference number 10. The shooting rest 10 is configured to support a firearm F (FIG. 4) while a user is aiming and firing the firearm. As explained in further detail below, the shooting rest 10 can be used in a bench rest mode and in a turret rest mode. If desired, the rest 10 could be used as a vise to hold a firearm in position for maintenance or gunsmithing procedures. The shooting rest 10 is intended for use with a long gun such as an AR-15 rifle, but other types of firearms can be used on the rest. Components of the shooting rest can be made of metal and/or plastic or any other suitable material.
In general, the shooting rest includes a frame 12, a forward firearm support 14, and a rear firearm support 16. The shooting rest 10 is arranged for the forward support 14 to support a forward portion of the firearm and for the rear support 16 to support a bottom of a hand grip portion of the firearm. The rear support 16 can be removable or can be omitted without departing from the scope of the present invention. Referring to FIG. 4, an AR-15 rifle indicated at F is shown mounted on the shooting rest 10. The rifle F includes a trigger T and a receiver R (including upper and lower receivers). Near the trigger T, the rifle F includes a pistol style hand grip G (broadly, “trigger hand grip portion”) that a user grips with fingers of the same hand that engages the trigger. Rearward from the trigger T, the rifle F includes a buttstock B (broadly, “butt portion”) configured to engage a shoulder of the user. In front of the trigger T, the rifle F includes a hand guard H (broadly, “forward portion”). When the rifle F is resting on the shooting rest 10, the hand guard H rests on the forward support 14, and the bottom of the pistol style hand grip G rests on the rear support 16. It will be appreciated that the rest 10 can be used to support other types of long guns without departing from the scope of the present invention. For example, shotguns and other rifles can be used. It will be appreciated that all long guns have a trigger hand grip portion to be grasped by the fingers of the user's trigger hand, although the trigger hand grip portion may have other forms than the pistol style hand grip of the illustrated AR-15 rifle. Moreover, other types of long guns may have a different type of forward portion, such as a forestock, a barrel, etc. that would rest on the forward support 14.
In the illustrated embodiment, the frame 12 is provided in the form of a stand having a tripod configuration. The frame 12 includes a yoke 18 and a three legs 20 extending from the yoke. The yoke 18 includes three leg connectors 18A. Each leg 20 includes a proximal end secured to a respective leg connector portion 18A of the yoke 18 by a fastener 24, and each leg includes a distal end opposite the proximal end. Feet 26 are provided at the distal ends for engaging a surface such as a surface of the ground. In the illustrated embodiment, the legs 20 extend from the yoke 18 in fixed orientations with respect to the yoke. The front leg 20 extends directly forward from the yoke and the rear legs 20 extend laterally and rearward from the yoke. A brace 21 extends between the two rear legs 20. Other types of frames can be used without departing from the scope of the present invention.
Referring to FIGS. 2 and 11, the front leg 20 is configured to adjust in length to provide coarse vertical aiming adjustment of the firearm F and/or to permit leveling of the yoke 18 with respect to the surface on which the rest is resting. The front leg 20 includes an upper leg section 20A and a lower leg section 20B, which is telescopically received in the upper leg section. The length of the front leg 20 is adjustable by telescoping the lower leg section 20B into or out of the upper leg section 20A. A compression connection is provided to releasably lock the front leg 20 at a desired length. The compression connection includes a sleeve 30 mounted on a distal end of the upper leg section 20A, a collar 32 threaded onto the sleeve 30, and a bushing 34 captured by a distal end of the sleeve and by the collar. In a locking configuration, the collar 32 is threaded sufficiently onto the sleeve 30 such that the bushing 34 is compressed by the sleeve and collar against an outer surface of the lower leg section 20B. In particular, the sleeve 30 has a ramped distal portion, and the collar 32 has a ramped distal portion, each of which engages respective ends of the bushing 34 and presses the bushing against the outer surface of the lower leg section 20B when the collar is threaded sufficiently onto the sleeve. To permit sliding of the lower leg section 20B with respect to the upper leg section 20A, the collar 32 is unthreaded sufficiently from the sleeve 30 to decrease friction between the bushing 34 and lower leg section to permit the lower leg section to slide into or out of the compression connection. Spacers 36 are provided at a proximal end portion of the lower leg section 20B to facilitate sliding motion of the lower leg section against an inner surface of the upper leg section 20A. Other configurations can be provided to permit coarse elevation adjustment without departing from the scope of the present invention.
Referring to FIGS. 9 and 10, the forward support 14 generally includes a stem 40, a hub 42, and a cradle 44. The arrangement permits rotation of the cradle 44 with respect to the frame 12 about a yaw axis YA for adjusting a horizontal aim of the firearm F and about a pitch axis PA for adjusting a vertical aim of the firearm. The cradle 44 is configured to receive the forward portion H of the firearm. The cradle 44 is connected to the frame 12 by the hub 42 and stem 40. The arrangement includes a first pivot connection of the stem 40 to the yoke 18 that defines the yaw axis YA, and a second pivot connection of the hub 42 to the stem 40 that defines the pitch axis PA. For reasons that will become apparent, the front support 14 can be referred to as a turret support.
The stem 40 includes a post 46 and a head 48. The post 46 extends through an opening in the yoke 18 and is connected to the yoke by an upper bearing 50A and a lower bearing 50B. Each bearing includes an inner race, an outer race, and a plurality of ball bearings between the inner and outer race. The lower bearing 50B includes a shoulder opposing a bottom surface of the yoke 18 and the upper bearing 50A includes a shoulder opposing an internal shoulder of the yoke. The stem 40 is rotatable win the bearings 50A, 50B with respect to the yoke 18 about the yaw axis YA. The stem 40 includes a lower section 40A and an upper section 40B secured to each other by a fastener 54 (e.g., bolt). The lower and upper sections 40A, 40B collectively define a neck 46A of the post 46 extending through the opening in the yoke 18. In manufacture, the upper section 40B may be moved downwardly into the yoke 18, the lower section 40A may be moved upwardly into the yoke, and the fastener 54 may then be installed to secure the upper and lower sections and upper and lower bearings 50A, 50B together. To secure the stem 40 axially in the yoke 18, the upper section 40B includes a shoulder 40C abutting the inner race of the upper bearing 50A, and the lower section 40A includes a shoulder 40D abutting the inner race of the lower bearing 50B.
A yaw brake 56 is provided in the form of an actuator including a threaded shaft 56A and a knob 56B. The threaded shaft 56A is received in a threaded opening 18B in the yoke 18 and has a distal end adjacent the neck 46A of the post 46. Friction of the distal end of the shaft 56A against the neck 46A can be increased or decreased by threading the shaft into or out of the yoke 18 using the knob 56B. In the illustrated embodiment, the neck 46A includes an annular break pad 58 which the distal end of the shaft 56 is positioned to engage. For example, the yaw brake 56 can be configured in a non-braking position, a braking position, or a locking position. In the non-braking position, the shaft 56A of the yaw brake 56 is threaded sufficiently out of the yoke 18 such that the distal end of the shaft is not engaging the neck 46A. In the non-braking position, the stem 40 is free to rotate about the yaw axis YA without braking by the yaw brake 56. In the braking position, the shaft 56A of the yaw brake 56 is threaded into the yoke 18 such that the distal end of the shaft is engaging the neck 46A and dampens rotation of the stem 40 about the yaw axis YA. In particular, friction between the distal end of the shaft 56A and the neck 46A is great enough to resist free pivoting of the stem 40 about the yaw axis YA but to permit rotation about the yaw axis when sufficient force is applied to the firearm F by the user. In the locking position, the shaft 56A of the yaw brake 56 is threaded into the yoke 18 such that the distal end of the shaft is engaging the neck 46A to create sufficient friction to prevent rotation of the stem 40 about the yaw axis YA. In use, the yaw brake 56 will typically be configured in the non-braking position or various degrees of the braking position.
Referring to FIG. 9, a pivot connection is provided between the hub 42 and the stem 40 to permit rotation of the cradle 44 about the pitch axis PA. The head 48 of the stem 40 has a generally cylindrical shape including opposite generally planar side faces, and the head has a bore extending through the head that opens out of the opposite side faces. The hub 42 includes a main body 42A and two arms 42B extending downward from the main body. A gap is provided between the arms 42B, and the head 48 of the stem 40 is received in the gap such that the hub 42 straddles the head with the arms on opposite sides of the head laterally outboard from the head faces.
Still referring to FIG. 9, the pivot connection between the hub 42 and stem 40 further includes brake shoes 60, brake pads 62, and a pitch brake 64. The pitch brake 64 includes an actuator including a carriage bolt 66 and a knob 68 threaded on a threaded portion of a shaft 66A of the carriage bolt. The shaft 66A defines the pitch axis PA and extends through the arms 42B, the brake shoes 60, the brake pads 62, and the stem head 48. The brake shoes 60 each include an outer portion 60A having a hexagonal outer surface and an inner portion 60B forming an inward facing annular engagement surface for engaging the respective brake pad 62. The hexagonal outer portions 60A of the brake shoes 60 are received in hexagonal openings in the arms 42B and are slidable in the openings along the pitch axis PA. The brake pads 62 are provided in the form of washers having opposite annular faces positioned to engage the faces of the brake shoes 60 and the faces of the stem head 48. The brake shoes 60 and brake pads 62 include openings through which the carriage bolt shaft 66A extends. The carriage bolt 66 is prevented from rotating with respect to the brake pad 62 adjacent a head 66B of the carriage bolt 66 by reception of a square section 66C of the carriage bolt shaft in a portion of the brake pad opening having a corresponding square shape. Desirably, the square section 66C of the carriage bolt 66 forms a friction fit with the brake pad 62 such that the brake pad is carried on and moves conjointly with the carriage bolt 66 if the carriage bolt moves axially. The knob 68 is threaded onto the opposite end of the carriage bolt 66 and is spaced from the hub by a spacer 70. The arrangement is such that rotation of the knob 68 tending to thread the knob on the carriage bolt 66 toward the hub 42 causes the brake shoes 60 to press the brake pads 62 against the opposite faces of the stem head 48. In particular, the knob 68 presses the spacer 70 against the right brake shoe 60, and the head 66B of the carriage bolt 66 presses against the left brake shoe 60. The pitch brake 64 can be configured in a non-braking position, a braking position, or a locking position. In the non-braking position, the knob 68 is threaded sufficiently away from the hub 42 to not press the brake shoes 60 toward the stem head 48, thus permitting free rotation of the hub and cradle 44 about the pitch axis PA. In the braking position, the knob 68 is threaded sufficiently toward the hub 42 so that the brake shoes 60 press inwardly against the respective brake pads 62 and thus cause the brake pads to press against the opposite faces of the stem head 48. Friction between the brake shoes 60 and brake pads 62 and friction between the brake pads and stem head 48 dampens rotational movement of the hub 42 about the pitch axis PA. In the locking position, the knob 68 is threaded sufficiently toward the hub 42 so that the brake shoes 60 press inwardly against the respective brake pads 62 to cause the brake pads to press against the stem head 48 with sufficient force to create locking friction. More specifically, the friction between the brake shoes 60 and brake pads 62 and friction between the brake pads and stem head 48 is great enough to prevent rotational movement of the hub 42 about the pitch axis PA. In use, the pitch brake 64 will usually be configured in the non-braking position or some degree of the braking position.
Other configurations for supporting the cradle 44 on the frame 12 can be used without departing from the scope of the present invention. For example, more or fewer than two pivot connections can be used. The yaw axis and pitch axis can be defined by a single pivot connection (e.g., ball pivot connection) or by multiple pivot connections. Other types of yaw and pitch brakes can be used, the yaw brake and pitch brake can be the same brake (e.g., in the case of a ball pivot connection), and the yaw and/or pitch brake can be omitted.
The cradle 44 will now be described in further detail with reference to FIGS. 5-9. In general, the cradle 44 includes a base 74, first and second jaws 76, and a clamp actuator 78 configured to move the jaws with respect to the base. The cradle 44 is configured to secure the forward portion H of the firearm F in the cradle by clamping the forward portion of the firearm. The base 74 defines a bed 74A between the jaws 76 on which the forward portion H of the firearm F can rest. In the illustrated embodiment, the base 74 includes a pad or overmolding of elastomeric material to provide a non-marring surface at the bed 74A for engaging the forward portion H of the firearm F. As shown, the bed 74A is formed by a multiplicity of closely spaced, hexagonal nubs. While the firearm F is resting on the bed 74A, the clamp actuator 78 can be used to move the jaws 76 into clamping engagement with the firearm. The cradle 44 defines a firearm axis FA (FIG. 6) extending between forward and rear ends of the cradle along which the forward portion H of the firearm F extends when clamped by the jaws 76. As will become apparent, the clamp actuator 78 is configured to move the jaws 76 at the same time and at the same rate of movement for clamping the firearm F in a centered position on the bed. In other words, the firearm axis FA is the same no matter the width of the forward portion H of the firearm being clamped.
The base 74 includes wings 74B positioned laterally outboard of the bed 74A for supporting the jaws 76. Standoffs 74C at forward and rear ends of the bed 74A connect the wings 74B to the bed. The base 74 defines rectangular openings between the bed 74A and the wings 74B in which the jaws 76 are received. The jaws 76 each include a rigid backing 76A and a non-marring pad 76B secured to the backing. For example, the pads 76B may be elastomeric material overmolded onto the backing 76A to define inward facing clamping surfaces of the jaws 76 facing the firearm axis FA. The pads 76B have smaller, closely spaced, hexagonal nubs for engaging the firearm F. The jaws 76 can be configured in a clamping position (e.g., FIG. 7) in which the jaws are relatively close to each other for clamping the firearm F and in a non-clamping position (e.g., FIGS. 5, 6, 8) in which the jaws are farther from each other and permit insertion and removal of the firearm therebetween.
The clamp actuator 78 includes a shaft 80 and a knob 82 secured to the shaft by a fastener 84 (e.g., roll pin) such that the knob and shaft rotate conjointly. The shaft 80 extends laterally through the wings 74B and bed 74A of the base 74. The shaft 80 includes a first threaded section 80A extending between the bed 74A and the left wing 74B and a second threaded section 80B extending between the bed 74A and the right wing 74B. The first threaded section 80A is left hand threaded, and the second threaded section 80B is right hand threaded. The first and second threaded sections 80A, 80B form threaded connections with threaded openings 76C in the jaws 76. The arrangement is such that rotation of the knob 82 in a first direction causes the jaws 76 to move closer to the firearm axis FA and to each other to clamp the firearm F, and rotation of the knob in a second opposite direction causes the jaws to move farther from the clamping axis and from each other to unclamp the firearm. It will be appreciated that the clamp actuator 78 moving the jaws 76 at the same time and at the same rate of movement causes the jaws to clamp the firearm F in a centered position on the bed 74A and with respect to the firearm axis FA no matter the width of the firearm at its forward portion H.
Referring to FIGS. 6-8, the cradle 44 includes first and second guides 86 configured to guide movement of the jaws 76 between the non-clamping and clamping positions. In the illustrated embodiment, the guides 86 each include a pair of slides 86A, 86B in the form of cylindrical rods extending between the bed 74A and wings 74B. Each pair of slides 86 includes a forward slide 86A forward of the clamp actuator 78 and a rear slide 86B rearward from the clamp actuator. The slides 86A, 86B are mounted on the base 74 by reception of opposite ends of the slides in openings in the bed 74A and wings 74B. In manufacture, the slides 86A, 86B can be inserted through the wings 74B into the bed 74B and be secured in position by installation of fasteners 88 (FIG. 8) such as E-clips on circumferential grooves in the slides through slots in the wings. The jaws 76 include followers 76D (FIG. 8) that are slidable along the slides 86A, 86B to guide movement of the jaws. In the illustrated embodiment, the followers 76D are provided in the form of circular openings in the jaws 76 through which the slides 86A, 86B pass.
Other cradles can be used without departing from the scope of the present invention. For example, other types of clamp actuators can be used. Other types of guides can be used, and the guides can be omitted. For example, other mating relationships of a guide and a jaw can be used. Moreover, the cradle need not be clampable on the firearm. The firearm can be secured in position on the cradle (e.g., by a strap, fastener, etc.) without being clamped between one or more movable jaws. Moreover, the cradle may include a bed without any upstanding members for supporting sides of the firearm.
Referring now to FIGS. 2, 3, 4, 12, and 13, the rear support 16 will now be described in further detail. The rear support 16 includes a platform 90 positioned to support a bottom of the trigger hand grip portion G of the firearm F. The platform 90 defines a deck 90A having an upwardly facing surface positioned to receive the bottom of the trigger hand grip portion G. The deck 90A includes a non-marring pad such as an elastomeric material overmolded onto a rigid backing of the platform. The deck 90A is also formed by a multiplicity of closely spaced, hexagonal nubs. The rear support 16 is mounted on the frame 12 between the two rear legs 20. In particular, the rear support 16 includes two arms 90B pivotally connecting the platform 90 to the brace 21. The arms 90B include openings through which the brace 21 extends and about which the platform 90 is pivotable with respect to the brace. The rear support 16 includes a jack 92 supporting the platform 90 and configured to adjust an elevation of the platform to adjust a vertical aim of the firearm F. In the illustrated embodiment, the jack 92 comprises a turn buckle including a wheel 92A and first and second shafts 92B, 92C connected to the wheel. The arms 90A of the platform 90 provide a space between the brace 21 and the remainder of the platform. An upper portion of the wheel 92A projects through this space for ease of access by the user, even when the grip G of the firearm F is resting on the platform. The turn buckle 92 is secured to the brace 21 by a pivot mount 94 including a collar 94A and first and second brackets 94B extending downward from the collar. The turn buckle 92 is secured to the platform 90 by two brackets 90C extending downward below the deck 90A. The first shaft 92B is pivotally secured to the pivot mount brackets 94B by a pin 96 and is rotatably connected to and fixed in axial position with respect to the wheel 92A. The second shaft 92C is pivotally secured to the platform brackets 90C by a pin 98 and includes a threaded portion forming a threaded connection with a threaded bore in the wheel 92A. The arrangement is such that rotation of the wheel 92A tending to decrease the length of the turn buckle 92 causes the turn buckle to lower the platform 90, and rotation of the wheel tending to increase the length of the turn buckle causes the turn buckle to raise the platform. Accordingly, the turn buckle 92 permits a user to raise and lower the trigger hand grip portion G of the firearm F resting on the deck 90A to lower and raise the vertical aim of the firearm.
Other types of rear supports can be used without departing from the scope of the present invention. For example, other types of jacks can be provided. Moreover, the rear support can be removable or be omitted without departing from the scope of the present invention. In one contemplated embodiment, the brace 21 is removable (e.g., by unfastening the brace 21 from the rear legs 20) to remove the rear support 16, such that the rest can be used without the rear support.
In a method of using the shooting rest 10, the shooting rest can be positioned at a location where the user desires to shoot and can be oriented with the forward and rear supports 14, 16 aligned in a general direction in which the user desires to shoot. The user then sets the firearm F on the rest 10 with the forward portion H of the firearm F on the forward support 14 and the bottom of the trigger hand grip portion G on the rear support 16. The clamp actuator 78 is used to clamp the forward portion H of the firearm F with the jaws 76 of the cradle 44. The shooting rest 10 can be used in a bench rest mode and in a turret rest mode. As used herein, bench rest mode refers to a mode in which the firearm F is resting on both the forward rest 14 and the rear rest 16. In this mode, the shooting rest 10 can be used as a bench rest fully supporting the firearm F and permitting fine adjustment of the aim of the firearm while supported by the shooting rest. The yaw and pitch brakes 56, 64 can be in the non-braking, braking, or locked positions, but desirably, the yaw and pitch brakes are in the braking or locked positions. The user can make coarse vertical aim adjustment by changing the length of the front leg 20, and can make fine vertical aim adjustment by rotating the wheel 92A of the turn buckle 92 of the rear support 16. Elevating or lowering the trigger hand grip portion G causes the firearm F to pivot about the pitch axis PA at the forward support 14. Major horizontal aim adjustments can be made by turning the shooting rest 10 to change the orientation of the legs 20, and fine horizontal aim adjustments can be made by sliding the bottom of the trigger hand grip portion G left or right on the deck 90A of the rear support 16. In this way, the shooting rest 10 can be used as a bench rest to fully support the weight of the firearm F and precisely aim the firearm at a desired target. In the turret rest mode, the user can lift the trigger hand grip portion G off the rear support 16 and rotate the firearm F as desired about the yaw axis YA and/or pitch axis PA of the forward support 14 to aim the firearm F. In the turret rest mode, the yaw and pitch brakes 56, 64 can be in the non-braking, braking, and/or locking positions, but at least one of the yaw and pitch brakes is not in the locking position. In the turret rest mode, the user benefits from the clamping of the cradle 44 on the firearm F and the tripod support of the frame 12 to provide stability to the firearm in aiming. The turret rest mode can be useful to the user in dynamic shooting situations, such as when shooting moving targets or when rapidly changing aim of the firearm toward various targets. In the turret rest mode, the user can rest the trigger hand grip portion G on the rear support 16 when waiting to acquire a target or when taking a break from shooting. When the user is finished using the rest 10, the firearm F is unclamped from the forward support 14 and removed from the rest.
It will be apparent that modifications and variations are possible without departing from the scope of the invention defined in the appended claims.
As various changes could be made in the above constructions and methods without departing from the scope of the invention, it is intended that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
