Definitions
- a satisfactory tennis racket should be lightweight and well balanced. Its frame, while being as far as possible stream-lined in contour parallel to the direction of racket movement when striking a ball, should at the same time possess high resistance to twisting and warping stresses as may arise when a ball strikes the racket off center. Further, it is necessary that the strings be attached to the frame through simple and eifective means, preferably with a conventional stringing machine; nor should the strings engage any sharp angles on the frame surface or be subjected to sharp bends since their service life would otherwise be reduced. Moreover the racket should not vibrate or be noisy in use.
- a racket frame thus constructed combines light Weight and strength. Its rigidity in the striking direction is very high even when provided with a low thickness dimension in said direction, so that the drag characteristic of the racket is low.
- Such a racket frame can be assembled with a handle made of metal, wood or other material, and such assembly can readily be eifected in such a way as to impart excellent resistance against torsional deformations to the racket as a whole.
- FIG. 1 is a simplified view of an improved tennis racket in front elevation
- FIG. 4 is a partial perspective View, on an enlarged scale, illustrating the core of the racket and showing one example of the means for connecting the frame with the handle;
- FIG. 5 is a partial front view illustrating a modified form of handle assembly
- FIG. 6 is a section on line VIVI of FIG. 5;
- FIG. 7 shows in cross section a perforated racket frame member provided with eyelets for string attachment
- FIG. 8 is a section on line VIII-VIII of FIG. 7;
- FIG. 9 is a fragmentary perspective view of a portion of the frame provided with a stringing jig or template for defining the pitch of a helix or coil used in the stringing process;
- FIG. 10 is a sectional view on a plane parallel to the plane of projection of FIG. 9 showing the manner in which the strings are engaged around the coil;
- FIG. 11 illustrates a serrated wire annulus positioned within the frame for string attachment
- FiG. 12. is a partial longitudinal section showing means for retaining the annulus with the strings attached thereto Within the frame;
- FIG. 13 is a perspective view illustrating some modified methods of winding the string attaching wire.
- FIGS. 14 to 17 illustrate various ways of mounting the strings on rings threaded around the frame member.
- FIG. 1 Shown in FIG. 1 is a tennis racket wherein the frame is constructed from a sectional member 1 of special configuration to be described, bent to the requisite shape of a loop, and further provided in this example with an arcuate bracing segment 2 for completing the oval frame.
- the frame thus constructed is connected to a handle 3 and is provided with strings 4 stretched across it.
- the sectional member from which the frame is formed includes two longitudinal beads 5 of preferably rounded form and interconnected by a web portion 6 of lesser thickness so as to define a pair of grooves 7 and 8 on either side of the member.
- the member is tubular. It can readily be formed to the desired cross sectional contour by using a tube of any suitable e.g. circular or oval cross section and deforming it by applying pressure along two opposed generatrices of it, e.g. by passing the tubular member through the nip between two rollers of corresponding contour, in one or more passes.
- the width and depth dimensions of the grooves 7 and 8 may be varied according to requirements.
- the sectional shaping operation may be so effected as to bring the opposite wall portions of the member into engagement in the web portion, as shown in FIG. 2; alternatively a space may be left between said wall portions as shown in FIG. 3.
- the brace member 2 consists of a length of the same (or a similar) contoured member as that from which the main part of the frame is made. This brace is firmly secured to the main frame part preferably by welding or brazing. Its positioning and assembly are greatly simplified since, as shown in FIG. 4, with the ends lo cut so as to conform with the shape of the contoured member 1,
- a racket frame constructed as thus described has excellent rigidity inthe direction of movement when hitting a ball, while being contoured in said direction for minimum air resistance or drag, and at the same time showing.
- the frame may be connected with the handle in any of various ways. Excellent assemblies have been obtained by providing the racket frame with adjacent spaced extensions 9 of the contoured frame member 1 as shown e.g. in FIGS. 1, 4 and 5, and inserting the end portions of such extensions into slots formed in a core member 11 made of wood or the like, then radially reinforcing the assembly by inserting it into an annular ferrule member 12; the ring or ferrule member 12 may, if desired, form anintegral part of a tubular handle 3 (FIG. 4).
- the recesses10 and the appropriate faces of the ring member may be shaped to conform with the contour of the frame member including the grooves 7 and 8 thereof; however a very strong assembly is found to be obtained even when the recesses 10 and ring member 12 are so formed as to engage only thebead surfaces of the frame member.
- this construction provides a convenient method of adjusting the weight of the racket by simply modifying the wall gauge thickness of the metal from which the sectional frame member is formed.
- strings may either be connected directly to the frame or through auxiliary attachment means, in various simple and effective Ways.
- the webportion 6 of the member 1 and spacer or brace member 2 are perforated at spaced locations and eyelets 15 having rounded edges are inserted through the perforations 14.
- both walls of the web portion 6 are preferably contiguous.
- the strings 16 are passed through the eyelets and it will readily be understood that with this arrangement the strings sustain no sharp bends; moreover the string portions 164: lying alongside the frame are positioned within the grooves 8 and are thus protected from damage e.g. when the outer periphery of the frame strikes or rubs against the surface of a tennis court.
- the eyelets may be dispensed with and the holes 14 formed with suitably rounded edges.
- FIGS. 9 and 10 the strings 16 are attached to the frame by way of a coil or helix 17 of piano wire or the like, wound about the frame member.
- This method of stringing the racket also derives considerable benefit from the puarticular type of frame member used according to the invention.
- the winding of the coil is facilitated in regard to the fact that the pitch of the coil should, as will be understood, be varied along the length of the frame memher in order to achieve the requisite spacing between the strings in the different parts of the frame.
- This problem of correct pitch variation is solved according to the invention by using during the stringing process, a template 18 contoured so as to be insertable into the outer groove 8 of the frame member, the template being formed along its outer surface with spaced notches 19 adapted to receive the turns of the coil 17.
- the template may remain in place in the finished racket or may be removed after the stringing operation.
- the coil is threaded through the notches 21a defined in the apices of the serrations.
- the strings 16 are passed across the bases 21b of the serrations and under the coil as shown in FIG. 12.
- the groove 7 provides the necessary clearance for the passing of the strings while the beads act to guide and retain the annulus thereby preventing the strings from shifting and vibrating in use.
- Such a string assembly is found to possess an especially desirable elasticity owing to the elasticity of the annulus 20.
- FIG. 13 illustrates some modified means of attaching the coil 17 to the frame member 1.
- the coil wire is so Wound as to present crossed'loops 17a to provide half-hitches as at 17b.
- the strings 16 are passed over the half-hitches and are thereby retained at the requisite spacings while preventing sharp bends in the string.
- the strings are retained in position by the beads 5 of the frame.
- the spacing between the spans of string 16 may if desired be increased by providing the half-hitch with a round turn as shown at 17c.
- a template is is desirably provided in the outer groove 8 of the frame member.
- tubular spacer 23 are omitted and castellated spacer strips 25 received in the outer groove 8 of the frame member are used instead.
- the ring 26 is formed with an inward projection or boss 27 in its side positioned outwardly of the racket which boss engages into the outer groove 8 of the frame member.
- the string 16 is retained in and guided by groove 7.
- the rings 26 may be spaced by means of spacers in the form of spots 23 of solder or plastic resin (e.g. Araldite) deposited within the groove 8 between the bosses of the rings to maintain the prescribed spacings between them.
- solder or plastic resin e.g. Araldite
- tennis racket should be construed in a broad sense so as to include rackets for games other than lawn-tennis, e.g. squash and badminton.
- a tennis racket comprising a frame shaped from a frame member of uniform cross sectional contour including a pair of spaced bead portions projecting from opposite sides of the racket frame and an interconnecting web portion defining a pair of longitudinal grooves respectively extending along the inner and outer peripheries of the frame; spacer means located within the outer one of said grooves and providing gaps at predetermined spacings along the outer periphery of the frame; string attachment means providing a plurality of loops passing around said frame member and within said gaps; strings engaging said loops and strung across the frame, portions of said strings extending into the inner said groove and a handle connected to said frame.
- said spacer means comprise an arcuate template strip member having one edge inserted in said outer one of said grooves and provided in its outwardly directed surface with notches defining said gaps.
- a racket as claimed in claim 1 wherein said string attachment means comprise rings surrounding the frame member and engaging said gaps.
- spacer means comprise spacer members positioned in said outer one of said grooves intermediate said rings and provided at their ends with notches wherein said rings engage.
