Abstract
Abstract A guard for a tennis racket or the like for preventing damage to the racket frame if the frame hits the playing surface when the player makes a ground shot. An elongated length of resilient, flexible material is fastened as a loop around the material of the frame at vulnerable points. The guard is readily applied and removed and is of sufficient thickness to serve as a bumper or guard when striking the playing surface.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
134 words
In combination with a racket having a frame, a length of resilient flexible homogenous material of sufficient thickness to act as a bumper and having a portion intermediate its ends of a thickness equal to at least one-third its width, said length being formed adjacent its ends with interengaging elements to permit said length to be looped around the frame of a racket at the upper portion thereof with said interengaging elements holding said loop on said frame thereby providing a sufficient length of the material to protect the frame from damage due to striking an object, said interengaging elements comprising an opening at one end adapted to receive the opposite end of said length therethrough and a protruberance at the opposite end adapted to engage the material of said length adjacent said opening.
Claim 2
Dependent Claim
134 words
In combination with a racket having a frame, a length of resilient flexible homogenous material of sufficient thickness to act as a bumper and having a portion intermediate its ends of a thickness equal to at least one-third its width, said length being formed adjacent its ends with interengaging elements to permit said length to be looped around the frame of a racket at the upper portion thereof with said interengaging elements holding said loop on said frame thereby providing a sufficient length of the material to protect the frame from damage due to striking an object, said interengaging elements comprising an opening at one end adapted to receive the opposite end of said length therethrough and a protruberance at the opposite end adapted to engage the material of said length adjacent said opening.
Claim 3
Dependent Claim
23 words
The combination of claim 1 wherein said length is of rectangular cross section and has a thickness equal to about one-half its width.
Claim 4
Dependent Claim
124 words
In combination with a racket having a frame, a length of resilient flexible homogenous material of sufficient thickness to act as a bumper and having a portion intermediate its ends of a thickness equal to at least one-third its width, said length being formed adjacent its ends with interengaging elements to permit said length to be looped around the frame of a racket at the upper portion thereof with said interengaging elements holding said loop on said frame thereby providing a sufficient length of the material to protect the frame from damage due to striking an object, said interengaging elements comprise a socket at one end of said length and a protruberance at the opposite end adapted to be press fitted with said socket.
Claim 5
Dependent Claim
124 words
In combination with a racket having a frame, a length of resilient flexible homogenous material of sufficient thickness to act as a bumper and having a portion intermediate its ends of a thickness equal to at least one-third its width, said length being formed adjacent its ends with interengaging elements to permit said length to be looped around the frame of a racket at the upper portion thereof with said interengaging elements holding said loop on said frame thereby providing a sufficient length of the material to protect the frame from damage due to striking an object, said interengaging elements comprise a socket at one end of said length and a protruberance at the opposite end adapted to be press fitted with said socket.
Claim 6
Dependent Claim
13 words
The combination of claim 3 wherein said length is of circular cross section.
