CROSSBOW WITH A CRANK COCKING AND RELEASE MECHANISM

摘要

A crossbow bowstring drawing mechanism comprises (1) a generally cylindrical housing having a first end and a second end; (2) a shaft rotatably mounted in the housing has a first end that at least partially extends through the housing first end; (3) at least one rope spool received on, and rotationally fixed to, the shaft intermediate the shaft first and second ends; (4) a handle operatively coupled to the shaft; and (5) a clutch mechanism received on the shaft. At least one of the rope spools is configured to attach to a first and a second end of a rope that is configured to he releasably attached to a bowstring. The clutch mechanism is configured to at least temporarily rotationally fix the shaft to the housing to prevent the shaft from rotating in a first direction and an opposite second direction until a force is exerted on the handle to overcome the frictional forces exerted by the clutch mechanism.

主权项

1. A crossbow drawing mechanism for use with a crossbow, the crossbow drawing mechanism comprising:
a. a housing having a cavity formed therein; b. a first shaft positioned at least partially in the housing cavity and rotatable with respect to the housing, the first shaft comprising:
i. a first end, andii. a second end, c. a first spool rotatably fixed to the first shaft proximate the first shaft first end; d. a second spool rotatably fixed to the first shaft intermediate the first spool and the first shaft second end; e. a ratchet wheel received on the first shaft intermediate the first spool and the second spool, the ratchet wheel comprising a plurality of teeth that are adapted to receive a pawl for rotationally fixing the ratchet wheel to the housing; and f. a crank operatively coupled to the first shaft such that when the crank is rotated the shaft rotates,
wherein the ratchet wheel rotationally fixes the first shaft to the housing in a first direction and allows the shaft to rotate with respect to the housing in an opposite second direction.
