Abstract

A layered composite slingshot having a metallic center or core, with overlaying spacing and outer layers. The individual layers are laminated together beginning with the metallic center. Pins are strategically inserted through the slingshot frame penetrating each layer, thereby locking each layer to one another.

Claims

1. A slingshot comprising:

a handle with two spaced arms, having

a. a metallic core having a handle portion and two arm portions;

b. and two overlaying outer layers that substantially correspond to a shape and size of said handle portion and said two arm portions of said metallic core,

wherein each side of said metallic core receives one of said overlaying outer layers affixed to said metallic core substantially covering each facing side of said metallic core, whereby said metallic core and said two overlaying outer layers form a unitary structure capable of withstanding stresses associated with use of said slingshot, the metallic core providing central strength and shock absorption, and said two overlaying outer layers providing supporting strength to said metallic core.

2. The slingshot of claim 1, wherein a spacing layer is placed between said metallic core and each of said overlaying outer layers.

3. The slingshot of claim 2, wherein a plurality of pins are inserted through said overlaying outer layers, said spacing layers and said metallic core, whereby said overlaying outer layers are locked to said spacing layers and said metallic core.

4. The slingshot of claim 1, wherein said metallic core is cut from a flat metal sheet.

5. The slingshot of claim 4, wherein said flat metal sheet is composed of stainless steel or aluminum.

6. The slingshot of claim 4, wherein said flat metal sheet has a thickness between 0.060″

and 0.5″

.

7. The slingshot of claim 4, wherein said metallic core is cut from said flat metal sheet using a water jet cutter.

8. The slingshot of claim 1, wherein said two overlaying outer layers are composed of wood.

9. The slingshot of claim 1, wherein said two overlaying outer layers are composed of a synthetic composite material.

10. The slingshot of claim 1, wherein interior sides of said two overlaying outer layers are scored with an abrasive creating additional surface area to affix to an adjoining element.

11. The slingshot of claim 1, further comprising laminating said two overlaying outer layers to said metallic core.

12. The slingshot of claim 1, further comprising cutting grooves into said two spaced arms to accommodate elastic bands.

13. The slingshot of claim 2, wherein said spacing layer is composed of fiber glass, thermoplastic sheet or thermoset composite.

14. The slingshot of claim 2, further comprising laminating said spacing layer to said metallic core and laminating one of said overlaying outer layers to said spacing layer.

15. The slingshot of claim 3, wherein said plurality of pins are constructed from stainless steel, copper, brass or aluminum.

16. The slingshot of claim 3, wherein said plurality of pins have a hollow center.

17. The slingshot of claim 3, wherein said plurality of pins contain a plurality of channels that run horizontally along the outside vertical surface of said plurality of pins.
