Abstract

An archery bow comprising a riser extending between opposing first and second ends. A limb is coupled to each end of the riser. Each limb has a first end for connecting to the riser and a second distal end. A pocket axle pivotally connects the first ends of each limb to one end of the riser. A strut assembly is operatively coupled between each of the limbs and the riser adjacent the pocket axle for selectively pivoting the limbs relative to the riser thereby allowing manual assembly and tuning of the bow by varying the distance between the distal ends of the limbs.

Claims

1. An archery bow comprising:

a riser extending between opposing first and second ends;

a limb coupled to each end of said riser, each limb having a first end for connecting to the riser and a second distal end;

an axle pivotally connecting at least one of said limbs to one end of said riser; and

a strut assembly operatively coupled between at least one of said limbs and said riser adjacent said axle for selectively pivoting said limb relative to said riser thereby allowing manual assembly and tuning of the bow by varying the distance between said distal ends of said limbs.

2. An archery bow as set forth in claim 1 wherein said strut assembly includes a strut power screw having a first end pivotally coupled to said limb and an opposite end pivotally coupled to said riser.

3. An archery bow as set forth in claim 2 wherein said strut assembly includes a screw nut retained by one of said limb and said riser and movably coupled to said strut power screw for movement along the length thereof to pivot said limb about said axle and riser.

4. An archery bow as set forth in claim 3 wherein said strut power screw has threads and said screw nut is threadedly attached to said strut power screw whereby rotation of said strut power screw forces said screw nut to travel along the longitudinal length of said strut power screw and pivot said limb about said riser.

5. An archery bow as set forth in claim 4 wherein said strut assembly includes a strut pivot support retained by said riser for rotatably supporting said strut power screw on said riser.

6. An archery bow as set forth in claim 5 wherein said strut power screw includes a first nut end and an opposite second distal end with said threads extending therebetween.

7. An archery bow as set forth in claim 6 wherein said strut pivot support includes a recessed detent for rotatably supporting said second distal end of said strut power screw.

8. An archery bow as set forth in claim 7 wherein said strut assembly includes a ball bearing seated between said second distal end of said strut power screw and said recessed detent of said strut pivot support to allow free rotation of said strut power screw between said limb and said riser.

9. An archery bow as set forth in claim 8 wherein said strut assembly includes a ball bearing retainer having an axially bore for rotatably housing said strut pivot support and a transverse bore for housing said ball bearing.

10. An archery bow as set forth in claim 9 wherein said riser includes a pair of spaces apart flanges having axially aligned holes for rotatably supporting said ball bearing retainer and strut pivot support.

11. An archery bow as set forth in claim 10 wherein said strut power screw includes a row of spaced apart indexing holes extending at least partially between said first and second ends.

12. An archery bow as set forth in claim 11 further including a ball plunger supported by said screw nut for cooperating with a select one of said indexing holes during rotation of said strut power screw for identifying the selected adjusted position of said limb relative to said riser.

13. An archery bow as set forth in claim 12 wherein said ball plunger includes a ball bearing for engaging said strut power screw and a spring compressed between said screw nut and said ball bearing for biasing said ball bearing against said strut power screw and indexing holes.

14. An archery bow as set forth in claim 13 further including a limb pocket having a base for fixedly supporting said first end of said limb and a pivot post for receiving said axle and pivotally attaching said limb to said riser.

15. An archery bow as set forth in claim 14 wherein said limb pocket includes a pair of spaced apart support posts extending from said base each having an axially aligned bore therethrough for rotatably supporting said screw nut between said posts.

16. An archery bow as set forth in claim 15 wherein said strut assembly includes a resilient shock absorber encasing said strut power screw between said limb and said riser.
