Abstract

In some embodiments, an archery bow riser comprises a body defining a first end, a second end and a grip portion. The body defines a shooting axis and comprises a first portion and a second portion. The first portion comprises a metal and the second portion comprises carbon fibers. The first portion extends to a first side of the shooting axis and to a second side of the shooting axis, and the second portion extends to the first side of the shooting axis and to the second side of the shooting axis.

First claim

The invention claimed is:

1. An archery bow comprising:
a riser engaged with a first limb fastener and a second limb fastener, the riser comprising metal and carbon fiber, the first limb fastener engaged with the metal, the second limb fastener engaged with the metal, the riser comprising a major tension surface and a major compression surface, the major tension surface comprising the metal, the major tension surface comprising the carbon fiber.

2. The archery bow of claim 1 , the major compression surface comprising the metal.

3. The archery bow of claim 2 , the major compression surface comprising the carbon fiber.

4. The archery bow of claim 1 , the metal comprising a first aperture arranged to receive the first limb fastener and a second aperture arranged to receive the second limb fastener.

5. The archery bow of claim 4 , wherein the first limb fastener comprises a first limb nut, the bow further comprising a limb bolt attached to the first limb nut.

6. The archery bow of claim 4 , the metal comprising a limb nut aperture aligned with the first aperture.

7. The archery bow of claim 1 , comprising limbs arranged to apply tension and compression to the riser, the metal arranged to receive the tension and the compression.

8. The archery bow of claim 7 , the carbon fiber arranged to receive the tension.

9. The archery bow of claim 8 , the carbon fiber arranged to receive the compression.

10. The archery bow of claim 1 , comprising an adhesive attaching the metal to the carbon fiber.

11. The archery bow of claim 1 , the carbon fiber comprising a first portion and a second portion, the first portion positioned to a first side of a shooting axis, the second portion positioned to a second side of the shooting axis.

12. An archery bow comprising:
a riser;
a first limb supported by the riser at a first support location and engaged with the riser by a first limb fastener;
a second limb supported by the riser at a second support location and engaged with the riser by a second limb fastener,
the riser comprising metal and carbon fiber, the metal engaged with the first limb fastener, the first limb and the second limb arranged to apply tensile forces and compressive forces to the riser;
the metal arranged to receive the tensile forces, the metal arranged to receive the compressive forces;
the carbon fiber arranged to receive the tensile forces.

13. The archery bow of claim 12 , the first limb fastener comprising a limb bolt and a limb nut, the metal comprising a first limb nut aperture.

14. The archery bow of claim 13 , the second limb fastener comprising a second limb bolt and a second limb nut, the metal comprising a second limb nut aperture.

15. The archery bow of claim 14 , the metal comprising a limb bolt aperture.

16. The archery bow of claim 12 , comprising an adhesive attaching the metal to the carbon fiber.

17. The archery bow of claim 12 , the riser comprising a major tension surface, the major tension surface comprising the metal.

18. The archery bow of claim 17 , the major tension surface comprising the carbon fiber.

19. The archery bow of claim 18 , the riser comprising a major compression surface, the major compression surface comprising the carbon fiber.

20. The archery bow of claim 12 , the carbon fiber comprising a first portion and a second portion, the first portion positioned to a first side of a shooting axis, the second portion positioned to a second side of the shooting axis.
