ABSTRACT:
Means for dampening vibrations in a strung game racket or a spoked wheel comprising a block of flexible, thermoplastic elastomer honeycomb bonded to and sandwiched between two thermoplastic facings. The device is inserted between at least two strings of the interwoven string diaphragm of the racket, or two spokes in a spoked wheel arrangement, in such a manner as to allow the exposed honeycomb core at the sides of the device to wrap around the engaged strings or spokes and hold the device in place. The device absorbs vibrations in the strings that originate from the striking surface when a ball is struck, and vibrations in the spokes emanating from normal use of a wheel.
