DEFINITION

Classification: 473/520

With sound-deadening, vibration-damping, or shock-absorbing

feature other than projectile- or hand-contact surface or with rebound reducing feature:

(under subclass 516) Subject matter wherein the projecting implement (a) comprises means, other than the outermost surface or layer of the part of the implement which is intended either to make contact with a projectile when it is struck (e.g., a rubber layer on the striking surface of a table tennis paddle, etc.) or to be grasped by a user thereof (e.g., a rubber grip strip wound around a tennis racket handle, etc.), specified as absorbing or attenuating vibrations of any frequency induced in the implement when it strikes a projectile or for preventing or reducing auditory or direct transmittal of such vibrations to the body of the user, or (b) comprises means intended to lessen or offset the force tending to cause the implement to bounce off a projectile when the implement and projectile contact each other.

(1) Note. A racket or paddle (whose construction as a whole is disclosed as (a) absorbing, attenuating, or blocking the transmission of vibrations than; (b) having fewer, lesser, lower, etc., vibrations than; or (c) reducing rebound over another racket or paddle having some other overall construction) is not classifiable here unless a clearly identified component(s) or feature(s) (whose disclosed function is to absorb, attenuate, or block the transmission of vibrations or to reduce rebound) is present.
