Description of the Invention (iii) The present invention relates to sports rackets, especially tennis rackets with racket heads and throat areas. They have an improved cross-sectional configuration. Up 'When the ball touches the net of the racket during the game, the energy transmitted to the racket causes the racket's frame to bend from its longitudinal axis. The bending of the racket causes the ball's accuracy to be destroyed when the ball rebounds away from the net It has been found that this racket's curvature caused by contact with the ball can cause the ball's intended flight path to deviate to one meter. Although some traditional rackets have been designed to be very rigid, avoiding racket deflection during exercise, but The disadvantage of these rackets is that increased stiffness requires the racket to be heavier than a standard racket. This increased racket weight reduces the mobility of the racket during exercise and promotes arm fatigue. Therefore, there is a need for a profile with enhanced stiffness characteristics Structured lightweight tennis racket.

The same reference numbers are used throughout the drawings to refer to the same or like parts. The present invention is based on the concept of designing different racket frame edge profiles, taking into consideration the specific stresses generated at different positions on the racket frame edge. For example, a circular racket frame edge profile has proven to be a suitable profile at locations where torsional stresses are predominant. Alternatively, a generally rectangular racket frame edge profile may be appropriate at those locations subject to greater bending stress. By designing the cross section of the head according to the main stresses obtained at various positions of the head, the racket according to the present invention can achieve optimized strength and mobility. Tennis rackets made in accordance with the present invention may, for example, weigh less than 200 grams (7.1 ounces). It is even better to design the profiles for those locations based on the main stresses on the grips of the throats and edges. In addition, according to the present invention, at the uppermost (far) portion of the frame edge, a thickness reduction can be made on a plane parallel to the plane formed by the racket net surface. Figures 1 and 2 show a front view and a side view of a conventional tennis racket 2. The tennis racket 2 includes a generally oval racket head 4, a throat area 6 and a grip portion 8. The head 4 includes a groove 10 (Figure 2) for accommodating a wear frame or a headband (not shown). The throat area 6 of the racket 2 provides a connection between the head 4 and the grip 8 and may include an opening 12. The throat opening 12 is formed by two frame edge sections 14 and 16 and a connection or bridge connecting the frame edge sections 14 and 16. A second connection element 20 is provided between the frame edge sections 14 and 16 In order to strengthen the throat area 6. In addition to the existence of the groove 10, the frame edge of the conventional tennis racket 2 shown in Figs. 1 and 2 includes a substantially constant cross-section. The cross-section of the frame edge is suitable for the country of China.

However, the bridge portion 18 has a lateral cross section larger than the uniform lateral cross section of the head 4. In order to describe the present invention in more detail, FIG. 1 shows the segmentation of the time within the head 4. FIG. The time segment (M2) sets the orientation in a manner similar to a clock, and 12 o'clock corresponds to the farthest part 22 of the head 4. Figures 3 to 5 illustrate a first embodiment of a tennis racket 30 according to the present invention. Except for those aspects described below, the structure of the racket 30 basically corresponds to the structure of the conventional tennis racket described above with respect to Figs. The racket 30 includes a head area 32, a throat area 34 with a throat opening 38, and a grip (not shown). Compared with the embodiment shown in FIG. 3, the throat area 34 can also be designed without opening 38 ', that is, the grip portion can be directly extended to the head area 32. The connecting elements between the proximal portion 42 of the head region 32 and the bridge portion 40 are also selective. Therefore, the throat area 34 may be formed only by the frame edge portion 46 extending from the proximal portion 42 of the head area 32 to the grip portion (not shown). As described above, the racket 30 according to the present invention includes a frame edge having a different profile according to a specific stress generated in each profile. The different sections each have a section coefficient suitable for the stress generated at that part of the edge of the racket frame. For the sake of clarity 'the rack profile referred to in the full detailed description represents the "transverse" profile of the racket. The transverse section at the racket frame edge position is bounded by a plane at the frame edge position, and the plane extends at the plane edge normal to a plane tangent to the outer surface of the racket frame edge. The enlarged part of the racket in FIG. 3 only shows half of the head region 3 2 and the throat region 34 of the racket 30. The other half of the racket 30 is the head area 32 and the throat area 34. This paper size applies to the Chinese National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before filling this page). ------- Order --------- · Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economy 7 487589 A7 -------_______ V. Description of the invention (5) Symmetric with the half shown. In the transverse sections 4a-4a, 4b-4b, 4c-4c, etc. along the frame edge of the racket 30, there is an interval of about 30 degrees. Secondly, in the throat area 34 of the racket, the cross section of Ruyi to 4t_4t is arranged at different foot distances according to the maximum stress occurring there. A section along each section of the racket 30 is shown in Fig. 4. According to the present invention, in the range of the frame edge, the maximum thickness of the racket frame edge on a plane perpendicular to the plane formed by the net surface is between about 20 and 35 mm, preferably 28.5 mm. In the sections shown in Figures 4a-4t, the maximum thicknesses of the racket frame edges on a plane parallel to the plane formed by the screen are listed, so together with the fixed thickness on the plane perpendicular to the plane formed by the screen The overall maximum thickness is 28.5, and a specific thickness ratio of these roughly ovals is obtained. These thickness ratios are marked below each section. For clarity, the thickness ratio in Figure 5 is again marked directly on each section. A substantially rectangular cross-section is provided in a region 30 of the racket subjected to a particularly high bending stress, for example, at a portion corresponding to the head region 32 (a region between the sections 4i to 41) of about two to four o'clock. The thickness ratio is in the range of 1.93 to 1.61. In order to absorb torsional stress, a generally ring-shaped racket frame edge portion is appropriate. Such a profile can be found, for example, at a part of the head region 32 corresponding to about 4.30 to 5.30 (in the regions of the sections 4n_4n, 40-40 and 4p-4p). Here, the thickness ratio of the portion of the head region 32 is approximately in a range between 105 and 132. In the grip and throat area 34 of the racket 30, a substantially rectangular cross section is preferred due to the high bending stresses occurring there, such as those shown in Figures 4q, 4r, and 4s. However, in the case of a racket with a bridging portion 40, due to the reinforcement provided by the bridging portion 40, the cutaway paper dimensions of the grip and throat area are applicable to China National Standard (CNS) A4 (210 X 297 mm) (Please read the notes on the back before filling out this page) • 1 ϋ H----- ^ ---------- Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economy 487589 V.

Therefore, the present invention is not limited to the thickness ratios and dimensions shown in Figs. 4a-4t and Fig. 5. It is within the scope of the present invention that the 疋 size and ratio vary depending on each application. The racket 30 shown in Figs. 3 to 5 is, for example, a tennis racket, and the size and thickness ratios described above are preferable for the tennis racket. However, those familiar with the art will readily recognize that other size and thickness ratios may be beneficial for other forms of racket, such as a soft racket (SCfaash racket). As mentioned above, the thickness ratios shown in Figures 4a to 4t only represent better printed values from the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. These ratios can range from ± 20%, particularly preferably within the range of 10%.

Although it is advantageous to provide at least one, preferably two, more bulges on the racquet frame rim area, it is still in the invention to omit one or all bulges on the racquet frame rim. Within range. Figures 6 to 12 show a second embodiment of a tennis racket according to the present invention. In this embodiment, the racket 30 includes a frame edge section of the racket, for example, formed in a hollow, substantially circular or oval shape, and is particularly suitable for receiving high torsional stress. Such a hollow profile is shown in, for example, Figures 8, 10, and 12, which respectively depict the racket 30 'corresponding to about 1:30 along lines 8-8 and about 5 points along lines 10-10. The bell, along line 12-12, corresponds to the cross section of the throat area. For the enlarged circular sections not shown in Figures 8, 10, and 12, the preferred thickness ratio of the l: I axis is in the range of 26:15 to 30:15, especially 28:15. Especially high outward torques occur in the area around the section 10-10, these torques are indicated by two arrows A in FIG. 6. The existence of pointing outward torque in the area of section 10-10 is unexpected, because we may expect that when the ball hits the racket net, the frame edge in the area of section 10-10 is twisted inward. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. In the throat area 34 ′ (sections 11-11 and 12-12), a rectangular section is preferred, based on the moments that occur in Nayi. However, due to the presence of the reinforced bridging portion 40 ', as shown in the illustrated embodiment, it is also possible that the cross-section of the frame edge portion 46' is a circular or oval cross-section. For racket frame edge regions where bending stresses occur predominantly, a substantially rectangular hollow profile is particularly preferred. This rectangular hollow section exhibits a high bending section factor and is therefore particularly suitable for absorbing bending stress. In the head area 32 ′, this bending stress occurs in the area 9-9 (corresponding to two 10 paper sizes applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) A7
