CLAW HAMMER

Abstract

A claw hammer includes a circular or oval recessed hole located on one lateral wall of a hammerhead thereof, a circular through hole located in a bottom wall of the recessed hole and cut through the other lateral wall of the hammerhead, a V-shaped opening extended from the border of the through hole and defining two abutment edges. When extracting a nail laterally, move the hammerhead horizontally to receive the head of the nail in the through hole and to abut the two abutment edges of the V-shaped opening against the shank of the nail, and then bias the handle of the claw hammer to extract the nail. Thus, the claw hammer provides an added lateral nail extracting function.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] Referring to FIGS. 1-3, a claw hammer in accordance with the present invention is shown. The claw hammer comprises a claw hammerhead 10 and a handle 20 connected with the hammerhead 10.

[0023] The hammerhead 10 is made of metal such as carbon steel or alloy steel, comprising a block body 11, a bell 12 formed integral with a front end of the block body 11, a claw 13 formed integral with an opposing rear end of the block body 11, and a lateral nail extractor 30 formed in one lateral side of the block body 11. The lateral nail extractor 30 comprises a recessed hole 31 located on one lateral wall 111 of the block body 11, a through hole 32 located in a bottom wall of the recessed hole 31 and cut through an opposite lateral wall 112 of the block body 11, and an opening 33 extended from the through hole 32 in direction toward a top wall 113 (or bottom wall 114) of the block body 11 for attaching onto the shank of a nail (not shown) and defining two abutment edges 34 at two opposite lateral sides thereof for abutment against two opposite sides of the shank of the nail. Thus, by means of the lateral nail extractor 30, the claw hammer of the present invention is practical for extracting a nail laterally.

[0024] Referring to the six views shown in FIGS. 4-9, the two opposite lateral walls 111,112 of the block body 11 are respectively terminating in a distal end edge of the claw 13 so that the two opposite lateral walls 111,112 are maintained smooth without any protrusion to interfere with the operation of the claw hammer in a narrow space (such as hammering a nail). Alternatively, the block body 11 of the hammerhead 10 can be configured to provide two protruding blocks 115 that are respectively disposed at two opposite lateral sides and respectively terminating in the claw 13. The two opposite lateral walls 111,112 are respectively formed on the protruding blocks 115. The through hole 32 and the opening 33 cut through protruding blocks 115 and the lateral walls 111,112. The through hole 32 is preferably a circular through hole for the passing of the head of a nail. The opening 33 is preferably an opening with a V-shaped cross section so that the two abutment edges 34 can be tightly abutted against the shank of a nail of any size, enabling the nail extractor 30 to extract nails of different sizes. Further, the recessed hole 31 is preferably a stepped recessed hole, having a circular or oval cross section for easy formation by a milling cutting tool.

[0025] When using the nail extractor 30 of the claw hammer of the present invention to extract a nail, as illustrated in FIG. 10, hold the claw hammer to move the hammerhead 10 horizontally toward the nail 40 to be extracted so that the head 41 of the nail 40 is inserted into the through hole 32, and then continuously move the hammerhead 10 horizontally to abut the two abutment edges 34 of the opening 33 against the shank 42 below the nail head 41 of the nail 40 (see FIG. 11). At this time, as illustrated in FIG. 12, the user can bias the handle 20 to extract the nail 40. In addition to the known structure of the claw 13 at the rear end of the hammerhead 10, the claw hammer of the present invention provides a lateral nail extractor 30, which allows the user to have more choices of use, in response to the needs of various nail extracting applications.

[0026] Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
