DEFINITION

Classification: 473/543

Prefabricated string assembly, means to prevent relative movement or wear at crossover points of strings, or having one or more strings with specified characteristic or arrangement:

(under subclass 524) Subject matter (a) comprising an array of strings associated together and placeable as a unit into the space bounded by the frame of a racket for subsequent securement thereto, (b) comprising a device to anchor the strings of the web of a racket to each other in order to reduce or eliminate relative movement therebetween, (c) comprising a device to reduce wear on a string of a racket at the point it crosses another string, (d) comprising a string in combination with a racket frame and wherein any characteristic of the string (e.g., material, surface configuration, etc.) is specified, or (e) comprising strings in combination with a racket frame and wherein the layout of the strings relative to each other or to the racket frame is specified.

(1) Note. A string, per se, is excluded herefrom unless (a) the string is expressly disclosed for use in the string web of a racket intended for striking a game projectile, and (b) the string possesses a surface characteristic (e.g., bumps, tackiness, low friction coating, etc.) expressly disclosed either to interact with the projectile (e.g., to enhance the grip of the string on the projectile, etc.) or to interact with another string at the point at which they cross (e.g., to prevent relative movement between the strings, etc.).
