DEFINITION

Classification: 473/540

Having string mounting feature other than mere through-holes lying in string plane:

(under subclass 524) Subject matter relating to(a) means for securing a string to the racket frame, (b) means for guiding a string through or about the racket frame, (c) means for protecting a string from contact by the racket frame, or (d) a specified arrangement of string holes extending into or through the racket frame.

(1) Note. A specified arrangement of string holes passing entirely through the racket frame and wherein the centers of all such holes lie in a common plane is excluded herefrom unless some additional string mounting feature is also specified.

(2) Note. A specified arrangement of strings is excluded from this and the indented subclasses even if such specified string arrangement would require a means for mounting, guiding, or protecting the string or would require an arrangement of string holes herein provided for, unless the means for mounting, guiding, or protecting the string or the string hole arrangement is claimed.
