Abstract

A trigger mechanism for use in a crossbow having a bowstring, the trigger mechanism comprising a housing having a slot formed therein, a trigger lever pivotally mounted in the housing and having a trigger that extends partially outside the housing, a catch pivotally mounted in the housing, and a disarm mechanism received in the housing that is moveable between a neutral first position and a disarm second position. The catch has a first end configured to retain the bowstring in a cocked position and a second end configured to operatively engage the trigger lever. When the disarm mechanism is in the disarm second position and the user draws the bowstring further into the housing slot, the trigger mechanism is configured to allow the catch to move from the catch first position into the catch second position without requiring the user to engage the trigger (e.g., squeezing or pulling the trigger).

First claim

What is claimed:

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, the trigger lever comprising a body portion and an arm, the body portion comprising a finger trigger, the arm moveable with respect to the body portion, the arm contacting the catch and retaining the catch in the cocked position; and
a disarm mechanism arranged to contact the trigger lever;
wherein the finger trigger is arranged to move the body portion and arm, thereby causing the arm to release the catch; and
wherein the disarm mechanism is arranged to contact the trigger lever and move the arm to release the catch.

2. The crossbow trigger of claim 1 , wherein the catch is arranged to move the arm with respect to the body portion as the catch moves to the cocked position.

3. The crossbow trigger of claim 1 , wherein the disarm mechanism contacts the arm.

4. The crossbow trigger of claim 3 , wherein the disarm mechanism does not contact the body portion.

5. The crossbow trigger of claim 1 , wherein the arm is supported by the body portion.

6. The crossbow trigger of claim 1 , wherein the body portion is arranged to rotate about a trigger axis and movement of the arm with respect to the body portion comprises a rotation of the arm about the trigger axis.

7. The crossbow trigger of claim 1 , the housing comprising a slot, at least a portion of the disarm mechanism oriented in the slot.

8. The crossbow trigger of claim 1 , wherein the disarm mechanism contacts the body portion.

9. The crossbow trigger of claim 1 , comprising a safety moveable with respect to the housing between a safe position and a fire position.

10. The crossbow trigger of claim 9 , comprising a disarm block moveable with respect to the housing, the disarm block having a neutral position and a disarm position, the disarm block arranged to retain the safety in its fire position when in the disarm position.

11. The crossbow trigger of claim 9 , the safety comprising the disarm mechanism.

12. The crossbow trigger of claim 11 , the safety comprising a body and the disarm mechanism, the disarm mechanism moveable with respect to the body.

13. The crossbow trigger of claim 12 , the safety comprising a biasing mechanism arranged to bias the disarm mechanism to a predetermined orientation.

14. The crossbow trigger of claim 1 , the disarm mechanism comprising a rotating lever.

15. The crossbow trigger of claim 1 , the disarm mechanism arranged to contact the bowstring.

16. The crossbow trigger of claim 1 , comprising a spring arranged to bias the arm to a predetermined position.

17. The crossbow trigger of claim 16 , the spring supported by the body portion.

18. The crossbow trigger of claim 16 , the spring supported by the housing.
