Abstract

Hammers suitable to different tasks are described. Each hammer includes features to reduce vibration and provides advantageous balance and mass distribution. The hammers have a handle portion comprising an I-shape sectional profile and a head comprising a cavity formed therethrough. Each hammer may further comprise various nail or other fastener removal structures, such as a claw, slots, notches, or the like. The hammer may further include a nail-starter with magnetic nail retention.

Claims (29)

1. A striking tool for riveting, the tool comprising:

a handle portion adapted to be removably received by a user having a first end and a second end; and

a head connected to a first end of said handle portion;

wherein a region of the head defines at least one weight reducing void, a cavity extending transversely through the head, the head further comprises a striking surface adapted to hit a rivet target at a first end of the head; and the head further defines a plurality of beams extending over a surface of the head wherein said beams extend in a direction substantially perpendicular to the striking surface of the head in order to absorb force which in the absence of said beams would be transmitted to the handle portion.

2. The striking tool of claim 1 wherein a cross-section of a portion of the handle is I-shaped.

3. The striking tool of claim 1 wherein the cavity formed through the head defines an upper portion and a lower portion of said plurality of beams.

4. The striking tool of claim 3 wherein the cavity extends to an exterior perimeter of the head.

5. The striking tool of claim 1 wherein the handle portion and the head are integrally formed from a single workpiece or substrate.

6. The striking tool of claim 1 wherein the beams are substantially incompressible in a direction of force applied by striking tool.

7. The striking tool of claim 6 wherein the beams absorb and dissipate forces other than the force applied by striking tool.

8. The striking tool of claim 1 wherein the head incorporates a claw extending from a second head end opposite of the first head end defining the striking surface.

9. A striking tool for stone or brick, the tool comprising:

a handle portion adapted to be removably received by a user having a first end and a second end; and

a head connected to a first end of said handle portion;

wherein a region of the head defines at least one weight reducing void, a cavity extending transversely through the head, the head further comprises a striking surface at a first end of the head, a plurality of cutting edges at a second end of the head; and the head further defines a plurality of beams extending over a surface of the head wherein said beams extend in a direction substantially perpendicular to the striking surface of the head in order to absorb force which in the absence of said beams would be transmitted to the handle portion.

10. The striking tool of claim 9 wherein a cross-section of a portion of the handle is I-shaped.

11. The striking tool of claim 10 wherein the handle further comprises a reinforcement web.

12. The striking tool of claim 9 wherein the striking surface includes a plurality of textured elements.

13. The striking tool of claim 9 wherein said plurality of cutting surfaces comprises a first cutting edge and a second cutting edge wherein the first edge extends beyond the second cutting edge.

14. The striking tool of claim 9 further comprising a nail starter integrally molded into the head wherein the nail starter comprises a nail receiving shaft, and an anvil surface.

15. The striking tool of claim 14 wherein the nail starter further comprises a magnet wherein said magnet is integrated into the head.

16. The striking tool of claim 9 wherein the head and handle are integrally molded forming a unitary body and the unitary body further comprises a notch adapted to removably engage a nail.

17. A sledgehammer striking tool, the tool comprising:

a handle portion adapted to be removably received by a user having a first end and a second end; and

a head connected to a first end of said handle portion;

wherein a region of the head defines at least one weight reducing void, a cavity extending transversely through the head, the head further comprises a first striking surface at a first end of the head and a second striking surface at the second end of the head; and the head further defines a plurality of beams extending over a surface of the head wherein said beams extend in a direction substantially perpendicular to the striking surface of the head in order to absorb force which in the absence of said beams would be transmitted to the handle portion.

18. The striking tool of claim 17 wherein a cross-section of a portion of the handle is I-shaped.

19. The striking tool of claim 17 wherein the head further a third striking surface on the head, wherein said third surface is defined opposite of the handle.

20. The striking tool of claim 17 wherein a protective webbing extends over a portion of the handle, said webbing extending from intersection of the striking tool head with the handle towards the opposite end of the handle, encapsulating said handle.
