1. A damping device for use with a striking implement having strings, comprising:
- a shape sustaining body having a pair of end faces each having a greatest longitudinal dimension and a greatest lateral dimension, said body further having a peripheral wall extending between said end faces and defining a thickness of said body, said greatest longitudinal dimension being greater than said greatest lateral dimension so that said body has a generally oblong shape; and
a peripheral groove formed in said peripheral wall such that the peripheral groove has a depth which is not uniform, the maximum depth of the peripheral groove being greater in said longitudinal dimension than said lateral dimension.

Abstract
The device comprises a body having a well which receives a damping fluid and a weight in the form of a lead or steel ball. The body has a groove which extends around the entire periphery of the body so as to receive the strings of a sports racquet. The groove and the well are oriented such that the well extends perpendicular to the plane of the racquet head when the groove entraps the strings of a racquet.

7. In combination with a sports racquet having a plurality of crossing strings, a handle, a throat connected to said handle, and a bow connected to said throat and adapted for mounting said strings, a damping device, comprising:
a body having a pair of end faces each having a greatest longitudinal dimension and a greatest lateral dimension, said body further having a peripheral wall extending between said end faces and defining a thickness of said body, said greatest longitudinal dimension being greater than said greatest lateral dimension so that the body has a generally oblong shape, both said longitudinal dimension and said lateral dimension being greater than the distance between adjacent strings on said sports racquet, a peripheral groove dimensioned to receive the strings of said sports racquet, said peripheral groove being formed in said peripheral wall such that the peripheral groove has a maximum depth which is not uniform, the depth of the peripheral groove being greater in said longitudinal dimension than said lateral dimension, and further wherein said damping device is mounted in said strings such that said groove receives strings to entrap said damping device among said strings so that the body overlaps the strings to a greater extent in the longitudinal dimension of the body than in the lateral dimension. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)
