Abstract

An anti-dry-fire mechanism for a crossbow includes a slotted mainframe and a movable trigger subassembly engaged with the slot for bidirectional movement between brace and drawn positions. The movable subassembly includes a bowstring latch forward of a bowstring catch and biased toward a bolt-absent position in which the bowstring latch obstructs forward movement of the bowstring past the bowstring latch; in its bolt-present position the bowstring latch permits such movement. With the movable subassembly in the drawn position, a bolt loaded onto the mainframe holds the bowstring latch in its bolt-present position against its bias; with the movable subassembly in the drawn position and no bolt loaded, the bowstring latch is held in its bolt-absent position by its bias. With the movable subassembly in the brace position, engagement of the mainframe and bowstring latch holds the bowstring latch in its bolt-present position against its bias.

Abstract

A crossbow includes a rail assembly and a limb assembly that can be assembled together and disassembled from one another. A release member is rigidly attached to one assembly and a retention member is attached to the other assembly. When the crossbow is assembled the release member is in a retained position; when the crossbow is disassembled the release member is removed from its retained position. In a release position the retention member permits movement of the release member into or out of the retained position; in a retention position the retention member prevents movement of the release member out of the retained position. The release and/or retention members can be adjusted to alter the force urging together the rail and limb assemblies. The retention member can be moved between the release and retention positions without using any tool.

Abstract

A safety device for a crossbow includes a wrist strap with a crank aperture in a palm portion thereof, and is secured around a user's wrist with the crank aperture over the palm of the user's hand. The crank aperture allows passage therethrough of a shaft of a crossbow crank, but prevents passage of a handle; wearing the wrist strap, the user can grasp the handle with the shaft extending through the crank aperture away from the palm of the user's hand. The wrist strap can be divided at its dorsal- wrist portion and include a closure to allow the wrist strap to be secured around or removed from the user's wrist as desired. Restraint of the crank handle by the crank aperture prevents uncontrolled spinning of the crossbow crank.

Abstract

An inventive mechanism includes stationary, reciprocating, winch, and stock subassemblies. The winch subassembly is mounted on the stock subassembly; the stationary subassembly is mounted at the rear of a slotted mainframe of the stock subassembly; the reciprocating subassembly moves along the mainframe between forward brace and rearward drawn positions. The winch subassembly takes up a rope to cause rearward movement of the reciprocating subassembly and lets out the rope to permit forward movement. The reciprocating subassembly includes a body engaged with the slot, a catch, and a sear. The stationary subassembly includes a trigger and an actuator. In the drawn position and retaining a bowstring, trigger movement causes actuator movement, which causes sear movement, which permits catch movement, which releases the bowstring. In its latched position, a trigger latch obstructs forward movement of the reciprocating subassembly from the drawn position; in its unlatched position, it permits that forward movement.
