Stocks for aimable devices are provided. In one aspect, stock has a body mechanically associated with the aimable device and movable to determine an aiming axis of the aimable device, a shoulder mount positioned proximate to one end of the body, a firing grip positioned apart from the shoulder mount along a length of the body; a support leg having a mounting end pivotably mounted to the body between the firing grip and an end of the body opposite from the shoulder mount and having a foot end movable between a first range of positions and a second range of positions and a receiver located between the mounting of the support leg to the body and the firing grip and adapted to releasably hold the support leg in the first range of positions wherein the at least one support leg provides a grippable forestock.

An energy storage system for a bow, the system defined at least in part by a riser, a first and second limb each having a first end coupled to the riser, a first and second wheel disposed at a second end of respective first and second limbs, a first and second power cord each having a first end coupled to the riser and a second end coupled to respective first and second wheels, and a string extending between and coupled to the first and second wheels.

A crossbow de-cocking mechanism may include a trigger mechanism, a trigger latch mechanism and a winch assembly. A first rotational input to the winch may move a trigger latch to disengage the trigger mechanism. A second rotational input to the trigger latch, opposite to the first, may move the trigger mechanism to move a crossbow bowstring from a cocked position to an un-cocked position.

A projectile launcher includes a frame that has a front and rear end. A projectile is configured to be propelled from the front end of the frame and the projectile is movable along a projectile axis during firing and arming of the projectile launcher. The projectile launcher includes a latch movable between the rear end of the frame and the front end of the frame along a travel axis and is attached to a crank mechanism via a tether. The projectile launcher also includes flexible limbs that drive a drawstring of the projectile launcher during the firing of the projectile launcher.

A nock for an archery arrow or bolt. The nock includes a radial indention configured to be engaged by a biased retainer of a trigger mechanism of a crossbow to retain the arrow or bolt in a desired position relative to the trigger mechanism and/or a bowstring. The radial indention may optionally comprise a groove defined generally continuously around a circumference of the nock. The radial indention is exposed when the nock is coupled with an arrow or bolt such that the radial indention may be engaged by a biased retainer within the trigger mechanism. The nock may further include a generally planar rearward bearing surface configured for being engaged by a bowstring. The nock of the present invention may be suitable for use with a multiple-shot crossbow or a single-shot crossbow. Other aspects of the present invention are directed to a projectile, a projectile retention system, and a crossbow.

An archery device and method are disclosed herein. The archery device, in an embodiment, includes a support configured to be moveably coupled to an archery bow. The archery device also includes a motion generator configured to be energized by an energy resource. The motion generator is configured to cause the support to move between a plurality of positions. The positions are associated with different levels of tension in a draw cord of the archery bow, and each of the levels has a magnitude greater than zero.

A crossbow includes a barrel having a flight section and a head. The head includes a main part and two extensions extending laterally from the main part. The main part is detachably connected to the flight section. Two cam units each include two first limb connected to the two extensions, and two cams. Two second limbs each are a curved limb and have a first end and a second end. The two first ends of the two second limbs are respectively and directly connected to two sides of the flight section or the head. A first string is wrapped around and connected between the two cams. Two second strings are connected between the cams and the second end of the second limbs. The weight center of the crossbow is located close to the user's body and is benefit for operating the crossbow with high balance and accuracy.

A stock includes a first end that has a stock mounting interface that is configured to mate with a like interface of a weapon. The first end has a quiver mounting feature configured to attach to a quiver. The stock includes a second end that has a quiver pocket defined therein to at least partially receive a portion of a quiver therein. The quiver pocket has at least one quiver grip positioned therein.

A crossbow assembly uses an arrangement with two pairs of limbs, with one pair of opposing limbs on each side of the stock. The two limbs within each pair are arranged in opposition to each other in a vertical plane. The limb tips are each connected to an axle assembly with respective limb cables. The axle has a pair of axle pulleys at opposing ends. A bowstring has opposing ends connected to each axle pulley. The bowstring extends forward from each axle pulley and extends across the stock, passing between two bowstring pulleys. The middle of the bowstring forms the nock point.

Crossbows are provided having a barrel with one limb and one winding system mounted to each of two opposite sides of the barrel. Each winding system has a limb string connected to one of the limbs and a limb cam about which the limb string can be wound. The limb cams are connected to and positioned apart from arrow string cams by respective interconnects and an arrow string extends across the barrel from an arrow string cam on one side of the barrel to an arrow string cam on the other side of the barrel. The limbs provide first forces urging the limb strings to unwind from the limb cams and the interconnects receive the first forces and convey a second forces to the arrow cams urging the arrow cams to rotate so as to wind the arrow strings onto the arrow cams. The arrow string is drawn against such urging.
