摘要： A crossbow including a frame with a riser and a center trail. First and second flexible limbs are attached to the riser. A draw string is received in string guide journals in first and second cams rotatably attached to the frame. The draw string unwinds from the string guide journals as it translates between a released configuration and a drawn configuration. The first and second cams include at least first and second power cable take-up journals, respectively. At least first and second power cables are attached to the first and second limbs and received in the first and second power cable take-up journals, respectively. As the crossbow is drawn from the released configuration to the drawn configuration the first and second power cables wrap onto the respective first and second power cable take-up journals.

摘要： A system for cocking mechanism for a crossbow that uses an elongated handle pivotally attached to the center support to move a traveler engaged with the draw string from a release configuration to a drawing configuration and into engagement with a trigger assembly. A ratcheting mechanism prevents the elongated handle from moving toward the open configuration as the crossbow is being cocked.

摘要： A bipod with a quick connect feature that engages with a standard rail. The bipod includes a pair legs pivotally attached at a pivot axis. A biasing mechanism is coupled to the legs that has a dead center position when the legs are in an intermediate configuration between a deployed configuration and a collapsed configuration. By shifting the biasing mechanism to one side or the other, the legs are automatically deployed to either the deployed configuration or the collapsed configuration. The biasing mechanism maintains the interface with the rail when in the deployed configuration and retains the lower portions of the legs adjacent each other in the collapsed configuration.

摘要： A string guide for a bow including first and second cams are mounted to first and second bow limbs, respectively. Each of the cams includes a string guide journal, an upper power cable take-up journal, and a lower power cable take-up journal. The draw string is arranged in a reverse draw configuration. The upper and lower power cables are received in each of the respective upper and lower power cable take-up journals and are displaced away from the respective draw string journals as the bow is drawn from the released configuration to the drawn configuration. In one embodiment, the upper and lower power cable take-up journals are helical in configuration. As a result of this configuration the cams can rotate more than 270 degrees, and preferably more than 300 degrees, as the bow is drawn from the released configuration to the drawn configuration.

摘要： A de-cocking mechanism for a bow having an energy storage assembly mounted to a center support with a draw string that extends across the center support coupled to the energy storage assembly. The bow includes a trigger assembly that retains the draw string in a drawn configuration. The de-cocking mechanism includes a de-cocking actuator that automatically releases the draw string onto the de-cocking mechanism when the de-cocking mechanism engages with the trigger assembly. The user can then manually move the draw string from the drawn configuration to a released configuration. The de-cocking mechanism is preferably combined with a cocking mechanism.

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.
