Abstract
A hammer includes a rigid elongated support structure, a head carried at one end of the support structure, and a manually engageable gripping portion. An end of the elongated support structure includes a pair of vibration-receiving portions terminating in spaced apart relation with respect to each other and spaced from each other in a direction parallel to a swing plane of the hammer. The manually engageable gripping portion is formed from a resiliently deformable material molded around a portion of the support structure including the vibration-receiving portions so as to fill the space between the vibration-receiving portions. Vibration forces acting in a direction parallel to the swing plane of the hammer are generated by striking a striking surface of the head against an object. A portion of the vibration energy is transmitted through the support structure to the vibration-receiving portions, where the vibration energy is dampened and thereby dissipated by the resiliently deformable material surrounding the vibration-receiving portions. Accordingly, the level of vibration transmitted to the hand of the user is reduced.
