Abstract

In at least one embodiment, a crossbow trigger assembly comprises a housing, a string catch and a trigger arranged to release the string catch. A safety member is moveable between safe and fire orientations, which prevents actuation of the trigger while in the safe orientation. An arrow sensing member is moveable between first and second orientations and prevents the safety member from assuming the fire orientation when the arrow sensing member is in the first orientation.

Claims

1. A crossbow trigger assembly comprising:

a housing comprising a guide channel, said guide channel being symmetrical across a longitudinal axis;

a string catch;

a trigger arranged to release said string catch upon actuation of said trigger;

a safety member moveable between safe and fire orientations, said safety member preventing actuation of said trigger in said safe orientation; and

an arrow sensing member moveable between first and second orientations along a linear axis, said arrow sensing member preventing said safety member from assuming said fire orientation when said arrow sensing member is in said first orientation, said arrow sensing member comprising a tab arranged to slide in said guide channel, said longitudinal axis of said guide channel being parallel to said linear axis;

said safety member comprising a continuous body having a first portion and a second portion, said first portion contacting said arrow sensing member, said second portion contacting said trigger.

2. The crossbow trigger assembly of claim 1, wherein said arrow sensing member comprises a contacting surface arranged to contact an arrow, said contacting surface comprising a slot.

3. The crossbow trigger assembly of claim 1, comprising a biasing member arranged to bias said arrow sensing member toward said first orientation.

4. The crossbow trigger assembly of claim 1, wherein said safety member is moveable along a linear path.

5. The crossbow trigger assembly of claim 1, wherein said safety member comprises a first detent and a second detent, said first detent corresponding to said safe orientation and said second detent corresponding to said fire orientation.

6. The crossbow trigger assembly of claim 1, wherein said arrow sensing member comprises an arrow guide slot.

7. The crossbow trigger assembly of claim 1, wherein said arrow sensing member comprises a second tab arranged to slide in a second guide channel said housing.

8. The crossbow trigger assembly of claim 1, wherein said safety member comprises a handle extending through an aperture in said housing.

9. The crossbow trigger assembly of claim 8, wherein said aperture is located on a sidewall of said housing.

10. The crossbow trigger assembly of claim 8, wherein said aperture is located on a rear wall of said housing.

11. The crossbow trigger assembly of claim 1, wherein said arrow sensing member comprises a single body.

12. The crossbow trigger assembly of claim 11, wherein said trigger comprises a single body arranged to contact said string catch and said safety member.

13. The crossbow trigger assembly of claim 1, wherein said trigger comprises a single body arranged to contact said string catch and said safety member.

14. The crossbow trigger assembly of claim 1, said arrow sensing member assuming said second orientation when an arrow is present, said arrow sensing member not preventing said safety member from assuming said fire orientation when said arrow sensing member is in said second orientation.

15. A crossbow trigger assembly comprising:

a housing comprising an elongate guide channel at least partially defined by a flat surface;

a string catch;

a trigger arranged to release said string catch upon actuation of said trigger, said trigger comprising a single body;

a safety member moveable between safe and fire orientations, said safety member preventing actuation of said trigger in said safe orientation; and

an arrow sensing member slideable between first and second orientations along a linear axis, said arrow sensing member preventing said safety member from assuming said fire orientation when said arrow sensing member is in said first orientation, said arrow sensing member comprising a tab arranged to slide in said elongate guide channel, said flat surface being parallel to said linear axis;

wherein said safety member comprises a continuous body arranged to contact said trigger and said arrow sensing member simultaneously.

16. The crossbow trigger assembly of claim 15, wherein said arrow sensing member comprises a body arranged to contact said safety in said first orientation and to contact an arrow in said second orientation.

17. The crossbow trigger assembly of claim 15, said arrow sensing member assuming said second orientation when an arrow is present, said arrow sensing member not preventing said safety member from assuming said fire orientation when said arrow sensing member is in said second orientation.

19. The crossbow trigger assembly of claim 15, said arrow sensing member comprising a continuous body having a first portion and a second portion, said first portion arranged to contact an arrow, said second portion arranged to contact said safety member.

18. A crossbow trigger assembly comprising:

a housing comprising an elongate guide slot, said guide slot at least partially defined by opposed parallel sidewalls;

a string catch;

a trigger arranged to release said string catch upon actuation of said trigger, said trigger comprising a single body;

a safety member comprising a single body moveable between safe and fire orientations, said safety member preventing actuation of said trigger in said safe orientation; and

an arrow sensing member comprising a single body moveable between first and second orientations along a linear axis, said arrow sensing member preventing said safety member from assuming said fire orientation when said arrow sensing member is in said first orientation, said arrow sensing member comprising a tab arranged to slide in said elongate guide slot, said opposed parallel sidewalls being parallel to said linear axis;

wherein said safety member contacts said trigger and said arrow sensing member simultaneously.
