1. In an archery bow sight of the type in which a sight pin is included in a pin assembly, mounted within a slot in a bracket, as a mechanism structured and arranged such that an elevation of the sight pin is adjusted by turning elevation adjustment structure of the sight pin assembly either clockwise or counterclockwise, the improvement comprising:

mounting a light gathering element in association with said sight pin assembly through linkage constructed and arranged to hold said element in a fixed rotational position without regard to rotation of said elevation adjustment structure;

whereby;

said light gathering element travels vertically with said sight pin proximate a sight plane.

Abstract

An improved sight for an archery bow providing a mechanism operable to convert a rotational input to a purely translational output. The mechanism may be adapted simultaneously and uniformly to adjust the windage of a plurality of sight pins. In another embodiment, the mechanism may be operable to adjust a vertical position of an individual sight pin carrying a fiber optic pickup.

1. In an archery bow sight of the type in which a sight pin is included in a pin assembly, mounted within a slot in a bracket, as a mechanism structured and arranged such that an elevation of the sight pin is adjusted by turning elevation adjustment structure of the sight pin assembly either clockwise or counterclockwise, the improvement comprising:
- mounting a light gathering element in association with said sight pin assembly through linkage constructed and arranged to hold said element in a fixed rotational position without regard to rotation of said elevation adjustment structure;
  
  whereby;
  
  said light gathering element travels vertically with said sight pin proximate a sight plane.

- - 2. The improvement according to claim 1, wherein said sight pin assembly includes a pinion member, a side edge of said slot is fashioned as a rack member, and said pinion member and said rack member are mutually arranged to adjust the elevation of said sight pin through a rack and pinion interaction.
  - 3. The improvement according to claim 1, further comprising:
    - a plurality of sight pins disposed in association with said bracket; and
      
      said bracket is configured and arranged in harmony with structure carried by a support arm for attachment of said bracket in a plurality of vertical positions with respect to said support arm, whereby moving said bracket between two such vertical positions simultaneously effects a corresponding uniform displacement on all said sight pins.
  - 4. The improvement according to claim 3, further comprising:
    - a windage adjustment mechanism including a peg extending from said bracket and reciprocally mounted within a housing carried by said support arm, said housing further containing a mechanism constructed and arranged to couple with said peg such that rotation of a knob associated with said housing effects linear extension or retraction of said peg with respect to said housing, depending upon a direction of rotation of said knob.

5. In an archery bow sight of the type in which a plurality of sight pins are included in a plurality of pin assemblies mounted within one or more slots in a bracket by structure arranged such that the elevation of the sight pins are individually adjustable, the improvement comprising:
- mounting said bracket to an archery bow by means of a mounting assembly including a support arm having a distal end carrying a windage adjustment mechanism including a peg extending from said bracket and reciprocally mounted within a housing at said distal end, said housing further containing a mechanism constructed and arranged to couple with said peg such that rotation of a knob associated with said housing is translated to effect a linear extension or retraction of said peg with respect to said housing and thereby to effect a corresponding horizontal movement of all said pins, depending upon a direction of rotation of said knob.

- - 6. The improvement according to claim 5, wherein said mechanism includes an inclined plane interface between a first component associated with said peg and a second component associated with said knob.
  - 7. The improvement according to claim 6, wherein said inclined plane interface is provided by an internal threaded surface of said peg interacting with the external threads of a shaft driven by said knob.
  - 8. The improvement according to claim 6, wherein said inclined plane interface is provided by an external threaded surface of said peg interacting with the internal threads of a shaft driven by said knob.
  - 9. The improvement according to claim 6, wherein said inclined plane interface is provided by an external surface of said peg adapted for interacting with the external threads carried by a shaft driven by said knob.

10. In an improved sight for an archery bow, the improvement comprising:
- a mechanism associated with said sight and operable to convert a rotatational user input into a purely translational output operable to adjust a component of said sight.
- View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
- - 11. The sight of claim 10, wherein:
    - said mechanism comprises a windage adjustment mechanism operable simultaneously and uniformly to effect a horizontal adjustment of a plurality of sight pins.
  - 12. The sight of claim 11, wherein:
    - said plurality of pins are carried on a base structure adapted for attachment, at a plurality of vertically disposed positions, to structure carried by a support arm of said sight whereby to permit a simultaneous and uniform displacement of said pins in a vertical direction.
  - 13. The sight of claim 10, wherein:
    - said mechanism comprises an elevation adjustment mechanism operable to effect a vertical adjustment of a sight pin.
  - 14. The sight of claim 13, wherein:
    - said elevation mechanism comprises a pinion engaging a rack, said pinion being operated by a driven interface adapted to receive a rotational driving input from a user effective to change a vertical position of said pin with respect to said sight.
  - 15. The sight of claim 14, wherein:
    - said elevation mechanism further comprises a lock adapted to resist changes in said vertical position of said pin, said lock being operated by a lock interface that is adapted to receive rotational locking and unlocking input from a user.
  - 16. The sight of claim 15, in combination with a wrench adapted on a first end to apply a rotational input to said driven interface, and adapted on a second end to apply a rotational input to said lock interface.
  - 17. The sight of claim 16, wherein:
    - said sight further comprises storage structure adapted to hold said wrench in a snap-fit engagement.
  - 18. The sight of claim 13, further comprising:
    - a light gathering element disposed in association with said sight pin for purely vertical translation between first and second elevations.
  - 19. The sight of claim 10, said mechanism comprising:
    - a knob element adapted to receive rotational input from a user;
      
      a slide member configured and arranged in harmony with holding structure to resist rotation of said slide member and to permit translational movement of said slide member with respect to said holding structure; and
      
      linkage structure between said knob and said slide member, said linkage structure being operable to move said slide member responsive to rotation of said knob.
