DEFINITION

Classification: 473/552

Grip or handle longitudinally or rotationally adjustable relative to head or shaft or changeable in length:

(under subclass 549) Subject matter (a) comprising a means, other than or in addition to the resilience of the material of the grip or handle itself, (1) for adjusting the position of the grip or handle along or about the longitudinal axis of the shaft of a racket or (2) for indexing, interlocking, or clamping the grip to the handle or shaft or the handle to the shaft in any one of a plurality of discrete positions or (b) comprising a means for adjusting the length of the grip or handle to make it either longer or shorter at the user's option.

(1) Note. Both (a) a spirally wound strip type of grip of fixed length or of stretchable material which may be wound about the handle or shaft with different pitches (thus changing the length of the handle or shaft which is covered by the grip) or wound at different longitudinal positions along the handle or shaft and (b) a tubular grip of fixed length or stretchable material which can simply be slipped over the handle or shaft to a greater or lesser extent or in different rotational positions are excluded herefrom unless they include an additional mechanism for adjusting their position (e.g., a position-adjusting screw, etc.) or for indexing, interlocking, or clamping them at any one of a plurality of discrete positions (e.g., a rib on the inside of a tubular grip for seating in one of a plurality of grooves in the handle or shaft).
