## Abstract

This invention provides for a strung sports racket a resilient insert mountable onto the rim of the racket's head to absorb vibration during play. The resilient insert is mounted between free ends of the racket rim and absorbs movement of the racket's frame whereby the free ends of the rim between which the insert is mounted have components towards each other and components perpendicular to the plane of the rim.

## Claims

### Claim 1

In a strung racket having a frame with a handle, a rim having an inside face and an outer face and strings through the rim, the rim having a discontinuity at its base to provide two spaced free ends, the improvement of:
a resilient insert between said free ends of said rim to absorb movement of the frame at said free ends, said resilient insert having opposite sides, the movement of the free ends having components towards each other and components perpendicular to a plane of the rim whereby to dampen the effect of the vibration transmitted to the handle from ball impact on the strings;
means for transmitting movement from the strings to said resilient insert comprising a strip overlaying the outer face of the rim and extending across the discontinuity;
tubular vibration-transmitting string sheaths on each of said sides of the resilient insert extending from said strip and through the rim and having free ends extending beyond the inside face of the rim, a string extending through each sheath; and
resilient clamp means, said free ends of said sheaths extending beyond the inside face of said rim a distance to be engageable by said clamp means and, said clamp means clamping the free ends of said sheaths to their respective strings.

### Claim 2 (depends on 1)

In a strung racket having a frame with a handle, a rim and strings across the rim, the rim having a discontinuity at its base to provide two spaced free ends, as claimed in claim 1, wherein said clamp means also clamps the strings laterally of said tubular string sheath.
