DEFINITION

Classification: 473/521

For racket or paddle:

(under subclass 520) Subject matter wherein the sound deadening, vibration damping, shock absorbing, or rebound reducing feature is adapted and intended to be in or with a projecting implement commonly known as a racket or paddle, which racket or paddle comprises a thin, broad, generally flat, projectile- striking member having a maximum length and width which are more or less equal (e.g., oval-shaped, etc.) and having a length and width which are each many times greater than the thickness of the member and wherein the striking member further (a) comprises a substantially rigid, generally flat, platelike element or is formed from a flexible sheet secured across a surrounding peripheral supporting frame (i.e., a paddle), or (b) is composed of a plurality of spaced apart, elongated strings, stringlike elements, or their equivalent stretched in an intersecting, parallel, radial, or concentric arrangement across a surrounding peripheral supporting frame to form a resilient web within the frame periphery (i.e., a racket).

(1) Note. See the Notes appended to subclass 524 below for a further elaboration of the type of projectile-striking implement that is considered to be a racket or paddle.
