DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
As shown in FIG. 1 and FIG. 2, the hammer structure according to a preferred embodiment of the invention is mainly a structure on a hammerhead 11 of a hammer 1. Particularly, an impact face 110 of said hammerhead 11 is formed with three straight sides 111 and one arc-shaped side 112. One of the three straight sides 111 is connected to and perpendicular to the other two straight sides, which are in turn connected to the arc-shaped side 112. Thus, the impact face 110 is formed roughly in the shape of a letter “D”. As a result, the surface area of the impact face 110 in said hammerhead is relatively larger than that of a conventional O-shaped impact face, given the same width and height.
Moreover, the impact face 110 may be made to have a rough surface.
According to the preferred embodiments shown in the figures, the three straight sides 111 are respectively located at the top side and two lateral sides of the hammerhead 11, while the arc-shaped side 112 is the bottom side. Here the top side refers to the side which is farthest from the free end of a handle when the handle is attached to the hammerhead.
Because the D-shaped impact face 110 of the invention has three straight sides 111 and one arc-shaped side 112, the impact face 110 of the hammerhead 11 is comparatively larger than the impact face of a conventional hammer that is shaped like the letter “O”, when both have the same width and height. Utilizing straight sides 111 for three of its sides allows the impact face 110 to encompass the intersection area at the corner (as shown in FIG. 3) when it is used to carry out hammering actions at corners between two walls or other similar locations. Therefore, whether the impact face of the invention is used to hammer on a single wall, corners between two walls, or other similar locations (as shown in FIG. 4 and FIG. 5), the point at which force is applied can be precisely controlled and consequently dead spots during hammering can be reached, thereby allowing one to make full use of hammers. As a result, the hammer of the invention can achieve hammering even within the dead spots, and this allows users to deal with all kinds of problems they might encounter during hammering.
In the hammerhead 11 of said hammer 1, a blade portion 113 extends from the other end of the hammerhead 11, and a V-shaped trough 114 is formed at one side of the blade portion 113. Moreover, the two lateral sides in the main body of the hammerhead 11 are formed with a flat portion 115 for sideways hammering action, respectively; the two flat portions 115 at both lateral sides are covered with adequate rough surface; a handle 12 is also assembled onto the hammerhead 11 to form a handheld hammer 1.
In summary, the hammer structure according to the preferred embodiment of the invention, with its overall assemblage and applications, is a novel structure that did not appear before; it can reach any dead spots that may be encountered during hammering, thus allowing hammering actions to be carried out despite the dead spots.
The embodiments disclosed in the paragraphs above only serve the purpose of elucidation, and are not to be used to limit the scope of the invention in any ways; any applications with similar structure that produces identical effects, or any variations derived therefrom, are viewed as within the scope of the invention.
