DEFINITION

Classification: 473/527

Paddle:

(under subclass 524) Subject matter wherein the striking member (a) comprises a substantially rigid, generally flat, platelike element or (b) is formed from a flexible sheet secured across a surrounding peripheral supporting frame (i.e., a paddle).

(1) Note. A flexible sheet may either be solid or be woven, knitted, etc. from one or more strands of material where the adjacent strands (or runs of the same strand) touch or have a gap therebetween no greater than the width of a strand. If the gap exceeds the width of a strand, the implement is to be considered to be strung-surface racket rather than a flexible-sheet paddle.
