Abstract

Certain embodiments of the present disclosure describe a trigger assembly for use in a crossbow. The trigger assembly includes a floating sear that is able to translate with a cable catch as the cable catch is rotated and also may rotate relative to the cable catch. As the cable catch moves from an uncocked position to a cocked position, the floating sear engages a pivot beam that is engaged with a trigger mechanism.

Claims

1. A trigger assembly attached to a crossbow with a bowstring cable, wherein said trigger assembly comprises:

a housing attached to a stock of the crossbow;

a trigger mechanism including a trigger, wherein said trigger mechanism is rotatably coupled to said housing;

a pivot beam rotatably coupled to said housing, wherein said pivot beam is operatively engaged with said trigger mechanism so that rotation of said trigger mechanism by pulling said trigger urges said pivot beam to rotate;

a cable catch rotatably coupled to said housing at a pivot point, wherein said cable catch is able to retain the bowstring cable of the crossbow, and wherein said cable catch is adapted to rotate about said pivot point between an uncocked position and a cocked position;

a floating sear rotatably coupled to said cable catch at a sear pivot wherein said floating sear is adapted to translate with the rotation of said cable catch around said pivot point and wherein said floating sear is also adapted to rotate relative to said cable catch around said sear pivot;

wherein when said cable catch is rotated from said uncocked position to said cocked position, said floating sear translates over said pivot beam and rotates so that said floating sear drops to a position forward of and abutting said pivot beam, thereafter holding said cable catch in said cocked position; and

,

wherein said pivot beam remains stationary when said cable catch is rotated between said uncocked position and said cocked position.

2. The crossbow trigger assembly of claim 1, wherein said trigger mechanism remains stationary when said cable catch is rotated between said uncocked position and said cocked position.

3. The crossbow trigger assembly of claim 1, comprising:

a safety mechanism, wherein said safety mechanism is movable between an engaged position and a disengaged position; and

,

wherein said cable catch may be rotated from said uncocked position to said cocked position while said safety mechanism is in said engaged position.

4. The crossbow trigger assembly of claim 1, wherein rotation of said cable catch into said cocked position when said bowstring cable is received in said cable catch causes a safety mechanism to move into an engaged position.

5. The crossbow trigger assembly of claim 3, comprising a detent, wherein said detent engages said safety mechanism to hold said safety mechanism in said engaged position or to hold said safety mechanism in said disengaged position.

6. The crossbow trigger assembly of claim 1, wherein said trigger mechanism includes a wheel that contacts said pivot beam, and wherein said wheel is adapted to roll along a surface of said pivot beam when said trigger mechanism rotates.

7. A trigger assembly attached to a crossbow with a bowstring cable, wherein said trigger assembly comprises:

a housing attached to a stock of the crossbow;

a trigger mechanism rotatably coupled to said housing;

a pivot beam including a forward surface, wherein said pivot beam is rotatably coupled to said housing, and wherein said trigger mechanism operatively engages said pivot beam so that rotation of said trigger mechanism by pulling said trigger urges said pivot beam to rotate;

a cable catch rotatably coupled to said housing at a pivot point, wherein said cable catch is adapted to rotate about said pivot point between an uncocked position and a cocked position;

a floating sear including a rearward edge, wherein said floating sear is rotatably coupled to said cable catch at a sear pivot;

wherein said floating sear is adapted to translate with the rotation of said cable catch around said pivot point and wherein said floating sear is also adapted to rotate relative to said cable catch around said sear pivot; and

,

wherein when said cable catch is in said cocked position, said rearward edge of said floating sear contacts said forward surface of said pivot beam and holds said cable catch in said cocked position.

8. The crossbow trigger assembly of claim 7, comprising:

a safety mechanism, wherein said safety mechanism is movable between an engaged position and a disengaged position.

9. The crossbow trigger assembly of claim 8, wherein rotation of said cable catch into said cocked position when said bowstring cable is received in said cable catch causes said safety mechanism to move into said engaged position.

10. The crossbow trigger assembly of claim 7, wherein said trigger mechanism includes a wheel that contacts said pivot beam, and wherein said wheel is adapted to roll along a surface of said pivot beam when said trigger mechanism rotates.

11. The crossbow trigger assembly of claim 7, wherein rotation of said trigger mechanism while said cable catch is held in said cocked position urges said pivot beam to disengage from said floating sear.

12. A trigger assembly attached to a crossbow with a bowstring cable, wherein said trigger assembly comprises:

a housing attached to a stock of the crossbow;

a trigger mechanism including a trigger, wherein said trigger mechanism is rotatably coupled to said housing;

a pivot beam rotatably coupled to said housing, wherein said pivot beam is operatively engaged with said trigger mechanism so that rotation of said trigger mechanism by pulling said trigger urges said pivot beam to rotate;

a cable catch rotatably coupled to said housing at a pivot point, and wherein said cable catch is adapted to rotate about said pivot point between an uncocked position and a cocked position;

a floating sear rotatably coupled to said cable catch at a sear pivot wherein said floating sear is adapted to translate with the rotation of said cable catch around said pivot point and wherein said floating sear is also adapted to rotate relative to said cable catch around said sear pivot;

a safety mechanism, wherein said safety mechanism is movable between an engaged position and a disengaged position; and

,

wherein said cable catch may be rotated from said uncocked position to said cocked position while said safety mechanism is in said engaged position.

13. The crossbow trigger assembly of claim 12, wherein said safety mechanism is positioned so that a user may move said safety mechanism between said engaged position and said disengaged position with one hand while keeping the hand adjacent the trigger.

14. The crossbow trigger assembly of claim 12, wherein rotation of said cable catch into said cocked position when said bowstring cable is received in said cable catch causes said safety mechanism to move into said engaged position.

15. The crossbow trigger assembly of claim 12, wherein said safety mechanism includes a safety bar defining an opening.

16. The crossbow trigger assembly of claim 15, comprising a detent, wherein said detent engages said safety bar to urge said safety mechanism to remain in said engaged position or to urge said safety mechanism to remain in said disengaged position.

17. The crossbow trigger assembly of claim 15, further comprising a safety pin, wherein said safety pin is engaged with said pivot beam so that said safety pin translates with rotation of said pivot beam.

18. The crossbow trigger assembly of claim 17, wherein when said safety mechanism is in said engaged position, said safety bar blocks movement of said safety pin so that said pivot beam is prohibited from rotating.

19. The crossbow trigger assembly of claim 17, wherein when said safety mechanism is in said disengaged position, said safety pin is aligned with said opening in said safety bar and said safety pin may translate into said opening upon rotation of said pivot beam.

20. The crossbow trigger assembly of claim 12, wherein said pivot beam remains stationary when said safety mechanism is moved between said engaged position and disengaged position.
