摘要： Crossbow bowstring positioning systems are provided. In one aspect of the invention a crossbow bowstring positioning system has a crank housing supporting an axle and positioning a first connector at a front facing surface of the crank housing, a length of rope connected between two separated points on the axle; a bowstring connector joined to the length of rope and connectable to a bowstring of the crossbow, a mounting having a buffer tube mount mountable to a buffer tube of a crossbow; and a crank operable to rotate the axle to control an extent to which the rope is wound onto the axle and a position of the bowstring connector relative to the axle. The crank housing and mounting can be readily assembled in a small space and an efficient manner while providing paths through which a force experienced by the axle during use can be resisted.

摘要： An arrow-shooting apparatus includes two limbs extending backward from a barrel. An upper pulley is connected to each of the limbs. Two lower pulleys and two wheels are supported on the barrel. Each of the wheels includes a rod, a primary-string stem and a secondary-string stem. A diameter of the rod is smaller than a diameter of the corresponding wheel. Each terminal section of a primary string extends around one of the wheels and is tied to the primary-string stem of the corresponding wheel. Each of two secondary strings is tied to the secondary-string stem of one of the wheels at an end and tied to the barrel at another end, and extends around the rod of one of the wheels, one of the lower pulleys, and one of the upper pulleys.

摘要： A crossbow de-cocking method may include the step of providing a trigger mechanism, a trigger latch mechanism and a winch assembly. A first input to the winch assembly may move a trigger latch to disengage the trigger mechanism. A second input to the trigger latch may move a crossbow bowstring from a cocked position to an un-cocked position.
