Abstract

The present disclosure is directed to a crossbow having first and second limbs with distal portions pivotally coupled to the frame at distal limb mounts and proximal portions pivotally coupled to the frame at proximal limb mounts. First and second cams are attached to the first and second limbs at locations between the distal portion and the proximal portions. A cocking mechanism slides on the center rail to engage with a draw string in the released configuration and slides to a retracted position to move the draw string to the drawn configuration and to engage with a trigger assembly.

First claim

What is claimed is:

1 . A crossbow comprising:
a frame comprising a center rail extending generally along a longitudinal axis of the frame; a first translation arm mount disposed at a first side of the frame and at a distal end of the frame; a second translation arm mount disposed at a second side of the frame and at the distal end of the frame; a first limb assembly disposed at a first distal end of the first translation arm mount, the first limb assembly comprising:
a first upper limb and a first lower limb;
a second limb assembly disposed a second distal end of the second translation arm mount, the second limb assembly comprising:
a second upper limb and a second lower limb;
a first pulley disposed between the first upper limb and the first lower limb; a second pulley disposed between the second upper limb and the second lower limb; a draw string coupled to each of the first pulley and the second pulley; one or more cords indirectly coupled to the draw string through one or more pulleys, the one or more cords operable to release the draw string; a trigger assembly comprising:
a trigger operable to fire the crossbow;
a safety operable to selectively disengage the trigger assembly;
a catch moveable between a closed position that holds the draw string in a drawn configuration and an open position that releases the draw string to a released configuration; and
a sear moveable between a cocked position that retains the catch in the closed position and a fire position that permits the catch to move to the open position to release the draw string;
a dry fire lockout mechanism that, when engaged, prevents release of the draw string if a bolt is not positioned on the center rail; and a de-cocking actuator that is selectively positioned between an inactive position in which the de-cocking actuator does not engage with the trigger assembly, and an active position, the de-cocking actuator comprising at least a portion that, while in the active position, engages an extension of the sear and rotates the sear in a direction to the fire position to thereby release the draw string independently from activation of the trigger, wherein the de-cocking actuator releases the draw string from the trigger assembly responsive to a user activating the de-cocking actuator into the active position and pulling the one or more cords to thereby disengage the dry fire lockout mechanism.

2 . The crossbow of claim 1 , wherein each of the first pulley and the second pulley is substantially circular.

3 . The crossbow of claim 2 , wherein the first upper limb and the first lower limb are rigidly coupled to the first translation arm mount, and wherein the second upper limb and the second lower limb are rigidly coupled to the second translation arm mount.

4 . The crossbow of claim 1 , wherein a proximal portion of each of the first limb assembly and the second limb assembly is not attached to the frame.

5 . The crossbow of claim 1 , further comprising:
a first power cable having a first end and an opposing second end, wherein the first end of the first power cable is coupled to the first pulley at least one power cable anchor of the first pulley; and a second power cable having a first end and an opposing second end, wherein the first end of the second power cable is coupled to the second pulley at least one power cable anchor of the second pulley.

6 . The crossbow of claim 1 , wherein the crossbow is configured to be coupled to a rotary crank cocking mechanism.

7 . The crossbow of claim 1 , further comprising:
at least one stirrup attached to the distal end of the frame; and one or more handles attached to respective ends of the one or more cords.
