Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
156 words
An apparatus for rebounding balls or similar objects brought into engagement therewith comprising a generally rectangular frame, supporting means adjacent each corner of said frame, additional supporting means on each side of said frame intermediate the corners thereof, a net having a shape corresponding to but slightly smaller than that of said frame, said net being supportingly engaged adjacent each corner by said supporting means but being free of engagement by said intermediate supporting means, and means for adjusting the tension of said net with respect to said frame means comprising an elongated memBer slidably passing through each of said supporting means and interlaced with the outer marginal portion of said net between each two corners, the ends of said elongated member being adjustably secured together, whereby tightening of said elongated member will tend to straighten the edges of the net between the corners thereof and to increase the tension around the border of the net.
Claim 2
Independent Claim
156 words
An apparatus for rebounding balls or similar objects brought into engagement therewith comprising a generally rectangular frame, supporting means adjacent each corner of said frame, additional supporting means on each side of said frame intermediate the corners thereof, a net having a shape corresponding to but slightly smaller than that of said frame, said net being supportingly engaged adjacent each corner by said supporting means but being free of engagement by said intermediate supporting means, and means for adjusting the tension of said net with respect to said frame means comprising an elongated memBer slidably passing through each of said supporting means and interlaced with the outer marginal portion of said net between each two corners, the ends of said elongated member being adjustably secured together, whereby tightening of said elongated member will tend to straighten the edges of the net between the corners thereof and to increase the tension around the border of the net.

Claim 4
Dependent Claim
20 words
An apparatus as in claim 2 wherein the ends of said cord are secured together by a releasable connecting knot.
Claim 5
Dependent Claim
18 words
An apparatus as in claim 3 wherein the supporting means comprise generally S-shaped members secured to said frame.
Claim 6
Dependent Claim
85 words
Apparatus as in claim 1 wherein said rectangular frame is composed of a pair of U-shaped sections connected together in spaced apart relationship by a pair of elongated tubular members telescopingly engaging the leg portions of said U-shaped members, and wherein inclined leg members are secured to said elongated tubular members, whereby rotation of said last-mentioned members in their engagement with the legs of the U-shaped sections will permit the legs to be placed flat against said net or extended outwardly therefrom into frame-supporting position.
