Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
173 words
A frame for a stringed sports racket comprising: a. a pair of interengaging members; b. each member comprising 1. a planar rim encircling an opening, shaped in accordance with any desired strung surface, said rim having an integral, coplanar throat and shank portion extending outward therefrom, 2. a continuous channel extending along the edges of said portion and around the outer periphery of said rim, 3. said channel having legs of unequal length which are perpendicular to the plane of said rim, the shorter leg interconnecting said outer periphery and the bottom of the channel, c. the pair of interengaging members defining a frame having, 1. a double thickness web made up of said planar rims and said portions in face to face engagement, and 2. a hollow tubular part extending along the edges of said portions and around the outer peripheries of said rims and made up of said channels whose longer legs overlap one another, the overlapping portions being in face to face engagement, d. adhesive means uniting said interengaging members.
