Abstract
1,237,958. Tennis &c. rackets. HELSING- BORGS GUMMIFABRIKS TRETORN A.B. 23 Jan., 1969 [23 Jan., 1968; 10 June, 1968], No. 3834/69. Heading A6D. A racket of the type in which the frame to which the stringing is attached is detachably supported by a main frame comprises a first member or detachable frame or bow A on which the stringing is mounted and a second member or main frame B (Fig. 1). The first member has a stringing frame 1 made of an outwardly facing U-channel, formed in a slightly oval closed configuration and supporting the stringing of the racket at its inner periphery. In the U-channel of the frame 1 is held the second racket member B which comprises a main frame 3 of twin metal tubes 11, 12 (Fig. 2) bonded together and fashioned in a central curved portion 6 which encircles and nests in most of the periphery of the outer frame 1, and two shanks 4, 5 extending from the portion 6 to define the shaft of the racket. The ends of the shanks enter the socket 16 of handle 9. A curved crosspiece 7 is disposed between the shanks 4 and 5 and at their juncture with the curved portion 6 of the main frame 3 nests in the U channel of the string- ing frame 1. A second crosspiece 8 joins together the shanks 4 and 5 and serves to clamp them together and draw the main frame 3 tightly into the U channel of the stringing frame 1. The latter is provided with a plurality of apertures 50 (Fig. 2) through which the strings 51 are laced. The crosspiece 8 comprises two abutting tubular sections 17 and 18 (Fig. 4) which are attached at their ends to sleeves 19 and 20 brazed to the shanks 4 and 5 and are brought into the abutting position by means of a coupling nut 21 which engages a flange 23 on the end of the tubular section 17 and rotates on the threaded nipple 22 of the tubular section 18. A locking pin 25 having caps 26 and 27 at its ends and passing through the apertures 53, 54 of the sections 17, 18, prevents the sections 17 and 18 from being separated more than a distance sufficient to enable the frame 1 to be detached from the frame 3. The handle 9 is formed of two symmetrical segments 55, 56 joined by screw 57 (Fig. 6). A socket 16 for receiving the shanks 4, 5 is provided in each handle section (Figs. 5 and 6) and the ends of the shanks are detachably held in position by a coupling means 10 (Fig. 6). The means 10 comprises a washer 31 mounted on a pivot pin 29 (Fig. 5) which extends through the bottom end wall 28 of the handle. Upon rotation of the pin 29 the washer 31 engages grooves 32 and 33 in the shanks 4 and 5 at 180‹ positions and thereby detachably engages the shanks in the handle. An alternative device for locking the handle 9 to the shanks 4 and 5 and clamping means for clamping the handle to the shaft are described.
