Abstract

A trigger mechanism for use in a crossbow comprises a housing having a first slot formed in a first side and a second slot formed in a second side opposite the first side. A trigger lever, a bowstring catch and a disarm mechanism are all moveably mounted in the housing. The catch has a first end configured to engage the trigger lever and a second end configured to retain the bowstring in a cocked position. The disarm mechanism is partially positioned in the second slot and is moveable between a fixed first position proximate the housing second slot toward a second disarm position toward the housing first slot. As the disarm mechanism moves from the first position into the second position, it engages the trigger lever causing it to move out of engagement with the catch first end allowing the user to release the bowstring using the bowstring cocking device from the trigger mechanism without having to engage the trigger.

Claims

1. A crossbow trigger comprising:

a housing;

a catch moveable with respect to the housing between a cocked position and a release position, the catch arranged to retain a bowstring in the cocked position and release the bowstring in the release position;

a trigger lever moveable with respect to the housing between a first position and a second position, the trigger lever arranged to retain the catch in its cocked position in the first position and to allow the catch to assume its release position upon moving to the second position;

a safety moveable with respect to the housing between a safe position and a fire position, the safety arranged to retain the trigger lever in its first position in the safe position and to allow the trigger to assume its second position in the fire position; and

a disarm mechanism moveable with respect to the housing between a first orientation and a second orientation, the disarm mechanism arranged to move the safety to its fire position and move the trigger to its second position when the disarm mechanism moves to its second orientation.

2. The crossbow trigger of claim 1, comprising a biasing mechanism arranged to bias the disarm mechanism to the first orientation.

3. The crossbow trigger of claim 1, comprising a disarm switch arranged to retain the disarm mechanism in its first orientation and prevent the disarm mechanism from assuming its second orientation.

4. The crossbow trigger of claim 1, the trigger lever comprising a first portion, a second portion and a finger trigger, the first portion arranged to contact the catch, the disarm mechanism arranged to contact the second portion.

5. The crossbow trigger of claim 1, the housing comprising a first slot and a second slot, a portion of the catch positioned in the first slot, a portion of the disarm mechanism positioned in the second slot.

6. The crossbow trigger of claim 5, the housing comprising opposed lateral sidewalls, the second slot comprising aligned openings in the opposed lateral sidewalls.

7. The crossbow trigger of claim 5, comprising a cocking device comprising an elongated rope, the elongated rope positionable in the second slot.

8. The crossbow trigger of claim 7, wherein the elongated rope moves the disarm mechanism to its second orientation.

9. The crossbow trigger of claim 5, the housing comprising a front surface and a back surface, the first slot extending through a front surface, the second slot extending through the back surface.

10. The crossbow trigger of claim 1, the safety arranged to slide with respect to the housing.

11. The crossbow trigger of claim 1, the disarm mechanism contacting the safety.

12. The crossbow trigger of claim 1, wherein the disarm mechanism moves the safety to its fire position as the disarm mechanism moves to its second orientation.

13. The crossbow trigger of claim 1, further comprising an arrow sensor arranged to prevent the safety from moving to the fire position.

14. The crossbow trigger of claim 13, wherein the disarm mechanism moves the arrow sensor as the disarm mechanism moves to its second orientation.

15. The crossbow trigger of claim 1, the trigger lever rotatable about a rotation axis, the disarm mechanism moveable along a linear axis.

16. The crossbow trigger of claim 15, the linear axis orthogonal to the rotation axis.

17. A crossbow trigger comprising:

a housing;

a catch moveable with respect to the housing between a cocked position and a release position, the catch arranged to retain a bowstring in the cocked position and release the bowstring in the release position;

a trigger lever moveable with respect to the housing between a first position and a second position, the trigger lever arranged to retain the catch in its cocked position in the first position and to allow the catch to assume its release position upon moving to the second position;

a safety moveable with respect to the housing between a safe position and a fire position, the safety arranged to retain the trigger lever in its first position in the safe position and to allow the trigger to assume its second position in the fire position; and

a disarm mechanism moveable with respect to the housing between a first orientation and a second orientation, the disarm mechanism biased to its first orientation, the disarm mechanism arranged to move the trigger to its second position when the disarm mechanism moves to its second orientation;

wherein the safety is moveable without moving the disarm mechanism.

18. The crossbow trigger of claim 17, comprising a disarm switch arranged to retain the disarm mechanism in its first orientation and prevent the disarm mechanism from assuming its second orientation.

19. The crossbow trigger of claim 17, the disarm mechanism arranged to move the safety to its fire position when the disarm mechanism moves to its second orientation.
