摘要： 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.

摘要： A cranking mechanism preferably includes a planetary gear, a drive shaft, a one way bearing, a clutch assembly, and at least one drive unit. The clutch preferably includes a clutch pressure plate, a flywheel, friction surfaces and at least one friction plate. Each drive unit includes a carrier, a spool and a flywheel. The one way bearing and the clutch assembly are axial on the drive shaft. A pressure locking nut is threaded on to a threaded end of the crank shaft to exert pressure on the clutch assembly. The sun gear is fixed on the drive shaft. The at least one drive unit is axial with the drive shaft, and fixed with the carrier of the planetary gear set. The pressure locking nut is tightened against the clutch assembly to frictionally engage the drive shaft with the at least one drive unit.

摘要： A crossbow includes a barrel with a groove in the top thereof. An aiming member is connected to the barrel. A rack is connected to the aiming member and located corresponding to the groove. A press piece includes a passage, a resilient member located in the passage and a press piece. The press piece is biased by the resilient member and partially protrudes beyond the press piece. Multiple restriction screws extend through the press piece and are threadedly connected to the rack. A spring is mounted to the threaded section of each restriction screw. The press piece is biased by the springs to resiliently contact the underside of the rack. An adjustment screw threadedly extends through the rack and contacts the press piece. The press piece is moved by rotating the adjustment screw to provide a constant force to the arrow in the groove.

摘要： A linear crossbow operates in a linear manner parallel to an arrow flight path. The linear crossbow includes a plurality of limbs and a rotatable string let out assembly. The limbs include free ends that are drawn towards the rotatable string let out assembly as a drawstring is pulled rearward. The limbs power the drawstring to propel an arrow along the arrow flight path from a front end of the crossbow.

摘要： A firing system for a crossbow having an arrow rest extending along an arrow rest axis, the firing system having a right limb and a left limb, the right limb being pivotable about a right limb axis and the left limb being pivotable about a left limb axis, the firing system further including a right cam and a left cam, the right cam having a right bow string groove and being rotatable about a right cam axis, the left cam having a left bow string groove and being rotatable about a left cam axis, the firing system having a bow string extending between the right and left cams and extending within the right and left bow string grooves, the bow string positionable between an un-cocked condition and a cocked or full draw condition wherein movement of the bow string from the un-cocked condition toward the cocked condition moves the right and left cams toward each other and pivots the right and left limbs about the right and left limbs axes respectively, the firing system further including a power assembly having a power cable and a spring assembly, the power cable having a forward end operably joined to the right and left limbs and a rear end operably joined to the spring assembly, the spring assembly having a power spring extending along a power spring axis between a first spring end and a second spring end and having a central spring opening, the power spring being below the arrow rest, the power cable extending through the central spring opening from the first spring end toward the second spring end, the rear end of the power cable being operably joined relative to the second spring end of the power spring, moving the bow string from the un-cocked condition to the cocked condition causing the right and left limbs to the pull forward end of the power cable forwardly wherein the operable engagement with the second spring end compressing the power spring by pulling the second spring end toward the first spring end to produce the shooting force to propel the archery arrow.
