Abstract
Abstract A method is disclosed for making a tennis, badminton or similar racket net. A board being provided with projecting nails, a thread or catgut is placed on the board along the sinuous contour of the cross-strings of a net and another thread or catgut is placed along the sinuous contour of the uprights of a net, using the nails as aids for defining said contours. Loops are formed at the connection between two successive cross-strings or uprights and the thus formed net is thereafter disengaged from the board.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
126 words
A tennis, badminton, or similar racket net, capable of being mounted to a frame, which comprises: a. cross-strings formed by the sinuous threading of a thread-like material; b. upright strings formed by the sinuous threading of a thread-like material, and interwoven with the cross-strings; c. tie means connecting each successive pair of uprights and cross-strings, respectively, thereby defining independently of the frame of the racket closed loops along the periphery of the net which may be used for applying tension to the net once it has been mounted on the frame, and d. at least one cord interwoven with the uprights and cross-strings near the closed loops in order to maintain a parallel relationship between each pair of successive uprights and each pair of cross-strings, respectively.
Claim 2
Dependent Claim
126 words
A tennis, badminton, or similar racket net, capable of being mounted to a frame, which comprises: a. cross-strings formed by the sinuous threading of a thread-like material; b. upright strings formed by the sinuous threading of a thread-like material, and interwoven with the cross-strings; c. tie means connecting each successive pair of uprights and cross-strings, respectively, thereby defining independently of the frame of the racket closed loops along the periphery of the net which may be used for applying tension to the net once it has been mounted on the frame, and d. at least one cord interwoven with the uprights and cross-strings near the closed loops in order to maintain a parallel relationship between each pair of successive uprights and each pair of cross-strings, respectively.
Claim 3
Dependent Claim
14 words
The net according to claim 1 in which the tie means is a sleeve.
Claim 4
Dependent Claim
14 words
The net according to claim 1 in which the tie means is a ligature.
Claim 5
Dependent Claim
39 words
The net according to claim 1 in which at least one of the closed loops defined by the uprights and the associated tie means is larger than the closed loops defined by the cross-strings and their associated tie means.
Claim 6
Dependent Claim
104 words
A tennis, badminton, or similar racket comprising: a. a handle; b. a frame containing a plurality of holes, and having a convex shape in the areas between said holes; c. a net containing peripheral closed loops which extend through the holes in the frame; d. a cable located along the periphery of the frame, and in a threaded relation with said closed loops; and e. a means for applying tension to said cable so that the closed loops are pulled out as the portions of the cable overlying the holes approaches the level defined by the apices of adjacent convex areas of the frame.
Claim 7
Dependent Claim
104 words
A tennis, badminton, or similar racket comprising: a. a handle; b. a frame containing a plurality of holes, and having a convex shape in the areas between said holes; c. a net containing peripheral closed loops which extend through the holes in the frame; d. a cable located along the periphery of the frame, and in a threaded relation with said closed loops; and e. a means for applying tension to said cable so that the closed loops are pulled out as the portions of the cable overlying the holes approaches the level defined by the apices of adjacent convex areas of the frame.
Claim 8
Dependent Claim
22 words
The racket according to claim 5 in which a groove is provided around the periphery of the frame for receiving the cable.
Claim 9
Dependent Claim
27 words
The racket according to claim 5 in which the means for applying tension in the handle is located at the end of the handle opposite the frame.
Claim 10
Dependent Claim
35 words
The racket according to claim 5 in which the frame is constituted by two symmetrical flanges, an where cross-pieces between said flanges define the convex shapes in the areas between the holes in the frame.
Claim 11
Dependent Claim
24 words
The racket according to claim 5 in which a means for applying tension directly to at least some of the closed loops is provided.
Claim 12
Dependent Claim
96 words
The racket according to claim 5 in which the net comprises: a. cross-strings formed by the sinuous threading of a thread-like material; b. upright strings formed by the sinuous threading of a thread-like material, and interwoven with the cross-strings; c. tie means connecting each successive pair of uprights and cross-strings, respectively, thereby defining closed loops along the periphery of the net, and d. at least one cord interwoven with the uprights and cross-strings near the closed loops in order to maintain a parallel relationship between each pair of successive uprights and each pair of cross-strings, respectively.
