ABSTRACT:
The protective assembly for tennis racquets of the present invention comprises an elastic holder strip and a pair of protective elements. The holder strip is pre-formed in an open oval shape so as to be easily wrapped over the headframe of a tennis racquet. A guide bar of open rectangular cross-sectional shape extends along the length of said holder strip with a pair of parallel walls on whose respective upper edges are formed a respective pair of wings extending laterally and downward therefrom. A plurality of string guides with axial holes are formed on the lower base of the guide bar extending inwards perpendicularly therefrom. The holder strip is wrapped over the headframe of a tennis racquet with the string guides inserted through the through-holes therein and the headframe threaded with string, passing through the axial holes of the string guides to form a net over the headframe. The two wings of the guide bar overhang a portion of the outer peripheral wall of the headframe to define a pair of reentrant cavities. The inner sides of the two protective elements, on which are formed enlarged buttress sections, are then squeezed and inserted into respective cavities to secure the protective elements in place. The outer sides of the protective elements extend to respective edges of the headframe's outer periphery. Protective elements of different weight can be exchanged to alter the weight of the racket.
