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.

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.

A crossbow including a center rail including a rail body and a riser, a first flexible limb coupled to the riser, a second flexible limb coupled to the riser, and a first cam mounted to the first flexible limb and rotatable around a first cam axis. The first cam including a first draw string journal defining a first draw string plane of rotation perpendicular to the first cam axis, and a first power cable take-up journal extending in a direction perpendicular to the first draw string plane of rotation. The crossbow further including a second cam mounted to the second flexible limb and rotatable around a second cam axis. The second cam including a second draw string journal defining a second plane of rotation perpendicular to the second cam axis, and a second power cable take-up journal extending in a direction perpendicular to the second draw string plane of rotation.

An archery bow can include a member that is adjustable or replaceable relative to a cam assembly. The member can be affixed to the cam assembly such that the member contacts one or more cables while the archery bow is in a fully drawn or near-fully drawn state. The member can be adjustable, replaceable, swappable, or otherwise modifiable to contact particular portions of the cable disposed at various distances from an axis of rotation about which the cam assembly is rotating. While in a first configuration, the member can contact a portion of the cable that is a first distance from the axis of rotation. While in a second configuration, the member can be replaced or repositioned to contact a portion of the cable that is a second distance from the axis of rotation.

The crossbow including a second cam mounted to the second flexible limb and rotatable around a second cam axis. The second cam including a second draw string journal defining a second draw string plane of rotation perpendicular to the second cam axis, and a second power cable take-up journal extending in a direction perpendicular to the second draw string plane of rotation.

A bow-type throwing tool includes a central body, a nocking string for an arrow, and elastic energy storage mechanism operated by the traction of the string. The elastic energy storage mechanism includes: two opposed primary levers connected with hinging to the central body, the nocking string being constrained by its opposite ends to opposite free ends of the primary levers; two opposed axial action thrust accumulators, defined on the central body; a loading element of the axial action thrust accumulators configured to induce a compression in the thrust accumulators following a traction of the nocking string.

An archery bowstring weight is provided including a sleeve that is encapsulated and suspended at least partially within an overmolded polymeric body forming an exterior of the bowstring weight. The sleeve can be a metal body, such as a ring, that floats or moves inside the polymeric body when the bowstring vibrates to dampen vibration of the bowstring. The sleeve can be isolated or separated from the bowstring by an inner wall of the polymeric body that is disposed between the bowstring and the sleeve when the weight is installed on the bowstring. The oscillation of the sleeve inside the overmolded polymeric body also can attenuate string oscillation and reduce string noise. A related method is provided.

The present invention relates to phosphorescent bowstring which emits a glow of light for ease of locating the bowstring in the dark or low light environment. The bowstring material can be manufactured with a phosphorescent pigment or coatings can be applied to it containing phosphorescent pigments.

In some embodiments, an archery bow comprises a rotatable member and at least one cable segment. A protector is supported by the cable segment. The protector is arranged to prevent the rotatable member from contacting the cable segment.
