Crossbow bowstring drawing mechanism
First Claim
1. A method of cocking a crossbow, comprising the steps of:
- providing a crossbow having a main beam, a bowstring and a trigger mechanism, said bowstring being selectively positionable into cocked and uncocked positions;
providing a drawing mechanism operatively connected to said beam, said drawing mechanism including first and second string portions, said drawing mechanism operatively connected to a pawl biased in a first position;
providing a claw member that is operatively connected to said first and second string portions;
engaging said claw member with said bowstring at said uncocked position;
operating said drawing mechanism;
placing said bowstring into said cocked position; and
, engaging said bowstring with said trigger mechanism.

Abstract
Crossbow bowstring drawing mechanisms which are integrated into or secured in the crossbow handle and which provide a straight and balanced draw to the crossbow bowstring to cock the crossbow bowstring in position in the crossbow trigger mechanism ready for firing. The cocking system can be manually operated or motorized, and can be manufactured as part of a crossbow or retrofit into a crossbow. An internal or external source of rotational power, such as hand crank, power screwdriver or an electrical motor, is preferably utilized in conjunction with a claw member including a bowstring engaging portion to translate rotation of the input source to longitudinal movement of the claw member to draw or release the crossbow bowstring resulting with minimal effort being expended by the user. The claw member may include adjustable cams used to center the claw member with respect to the crossbow barrel.

14. A crossbow, comprising:
-
a longitudinally extending main beam having a longitudinally extending track thereon;
a pair of outwardly extending arms having distal ends, said pair of outwardly extending arms extending transversely from opposite sides of maid longitudinally extending main beam;
a crossbow bowstring attached to said distal ends of said pair of outwardly extending arms;
a crossbow trigger mechanism mounted on said longitudinally extending main beam;
a claw member mounted to move along said longitudinally extending track of said longitudinally extending main beam, said claw member having a first attachment point on a first side of said longitudinally extending track and a second attachment point on a second side of said longitudinally extending track, said claw member being capable of moving said crossbow bowstring from a first uncocked position to a second cocked position in said crossbow trigger mechanism; and
a crossbow bowstring drawing mechanism including a first string member along said first side of said longitudinally extending track, said first string member having a distal end attached to said first attachment point of said claw member, and a second string member along said second side of said longitudinally extending track, said second string member having a distal end attached to said second attachment point of said claw member, said crossbow drawing mechanism being capable of retracting said first string member and said second string member along said longitudinally extending track at substantially the same rate, said crossbow drawing mechanism further comprising a pawl biased in a first position. - View Dependent Claims (15, 16, 17)
