Abstract

A bowstring release assembly comprises a housing that receives the operative components that facilitate bowstring release motion. A gear assembly initiates and actuates the release motion. A rack and a pinion form the gear assembly. A trigger operates the rack to translate within the housing. The pinion is formed on a first portion of the peripheral surface of a rotary member which rotates in response to operation of the rack. A cam is formed on a second portion of the peripheral surface of the rotary member. The cam cooperates with a roller disposed on one end of a restraint assembly mounted on a pivot pin within the housing to allow bowstring release. A peg disposed on a second end of the restraint assembly engages the bowstring for restraint and pivots away upon actuation for release. A rope loop anchored to the housing may be provided to wrap around the bowstring and hook onto the peg for restraint.

Claims

1. A bowstring release assembly, comprising:

a housing;

means cooperating with said housing for engaging a bowstring for restraint and release; and

a gear assembly, including a rack and a pinion, for initiating and actuating said engaging means to release said

whereby uniform and consistent bowstring release motion is provided during recurrent use.

2. The bowstring release assembly as in claim 1, wherein is included a trigger cooperating with said rack to initiate the actuating motion of said release assembly.

3. The bowstring release assembly as in claim 1, wherein said pinion is formed on a first portion of the peripheral surface of a rotary member.

4. The bowstring release assembly as in claim 3, wherein a cam is formed on a second portion of the peripheral surface of said rotary member.

5. The bowstring release assembly as in claim 4, wherein said engaging means comprises a restraint assembly that cooperates with said gear assembly.

6. The bowstring release assembly as in claim 5, wherein said engaging means further includes a rope loop anchored to said housing and cooperating with said restraint assembly to restrain and release said bowstring.

7. The bowstring release assembly as in claim 5, wherein said restraint assembly comprises a roller disposed on a proximal end to cooperate with said cam and a peg disposed on a distal end for restraining said bowstring.

8. The bowstring release assembly as in claim 7, wherein said restraint assembly is mounted on a pin to allow said peg to pivot from a restraint position to a release position as said roller moves in response to operative engagement with said cam.

9. The bowstring release assembly as in claim 1, wherein said engaging means comprises a restraint assembly that cooperates with said gear assembly.

10. The bowstring release assembly as in claim 9, wherein said engaging means further includes a rope loop anchored to said housing, said rope loop cooperating with said restraining assembly to restrain and release said bowstring.

11. A bowstring release assembly, comprising:

a housing;

means cooperating with said housing for engaging a bowstring for restraint and release;

means for initiating through translational motion the release of said bowstring; and

means responsive to said initiating means for actuating said engaging means to release said bowstring;

said initiating means including a trigger cooperating with a rack and said actuating means including a pinion whereby uniform and consistent bowstring release motion is provided during recurrent use.

12. The bowstring release assembly as in claim 11, wherein said actuating means operates through rotary motion to actuate said engaging means.

13. The bowstring release assembly as in claim 11, wherein said initiating means and said actuating means comprise a gear assembly.

14. The bowstring release assembly as in claim 11, wherein said pinion is formed on a first portion of the peripheral surface of a rotary member.

15. The bowstring release assembly as in claim 14, where a cam is formed on a second portion of the peripheral surface of said rotary member.

16. The bowstring release assembly of claim 15, wherein said engaging means comprises a restraint assembly that cooperates with said cam.

17. The bowstring release assembly of claim 16, wherein said restraint assembly comprises a roller disposed on a proximal end to cooperate with said cam and a peg disposed on a distal end for restraining said bowstring.

18. The bowstring release assembly of claim 17, wherein said restraint assembly is mounted on a pin to allow said peg to pivot from a restraint position to a release position as said roller moves in response to operative engagement with said cam.
