Abstract
Abstract A tennis racket handle is slidably adjustable along a shank and a ball movable with the handle is engageable in any of a plurality of longitudinally spaced depressions on the shank. In one form the ball is urged away from the depressions by a spring and can be held in a selected depression only by a firm grip on the handle. In another form a spring and cam normally holds the ball in a selected depression and is released by pressing a button extending to the exterior of the handle.

Total Claims: 6
Claim 1
Independent Claim
272 words
A tennis racket having a head and a shank fixed thereto; a handle slidably mounted on said shank for sliding movement thereon toward and from said head and having a hand-grip portion; interengageable means on said shank and on said handle for releasably latching said handle in each of a plurality of positions along said shank; said interengageable means on said handle being movably carried thereby for movement thereon toward and from said shank; resilient means urging said interengageable means on said handle in a direction outwardly of said handle; manually interengageable means on said hand-grip portion, adjacent the outer surface thereof, positioned to be engageable by the hand of a player gripping said hand-grip portion and being movable to move said interengageable means on said handle against the urging of said resilient means whereby a player may, by manipulating the hand holding the racket, selectively latch or release said handle relative to said shank; and said interengageable means on said shank comprising a plurality of longitudinally spaced depressions therein and wherein said interengageable means on said handle comprises a ball engageable in said depressions to latch said handle against movement, said resilient means being an outwardly biased leaf spring secured at one end thereof to said handle and extending adjacent the outer surface thereof, said ball being fixedly mounted on the other end of said spring whereby a firm grip by the player's hand engages said ball into one of said depressions and thereby holds said handle latched to said shank and whereby relaxation of said grip permits said leaf spring to spring outwardly and withdraw said ball from the depression.
