Definitions
- the invention relates to a racket for a ball game, in particular for tennis, according to the preamble of claim 1.
- a racket of the type mentioned is known, in each case one of the ends of the strings of the cross string and the longitudinal string is connected to a tensioning device.
- the strings of the strings are each guided over pulleys on the frame, the strings must be stretched evenly over the entire string excluded because the tension of the strings can practically not propagate due to the numerous crossing points. This is made even more difficult by the plain weave of the covering.
- the object of the invention is to design a racket of the type mentioned in the introduction in such a way that it is possible to set a tension which is practically uniform over the entire covering, at least of the transverse covering.
- the further development according to claim 3 ensures a secure attack of the loop ends on the tendon.
- the embodiment according to claim 4 offers the advantage that the tension string can compensate for certain different tensions in the individual attached loops of a string due to its elasticity.
- the tension string can be designed like a ball chain.
- the embodiment according to claim 5 enables a very direct influence on the string tension of the fabric due to the tension rod.
- Claim 6 describes a simple type for the adjustable tensioning of the longitudinal covering, a tensioning device which can be used in particular where it is not possible or only possible to detect the loops of a covering. This tensioning device can also be used in addition to the aforementioned tensioning device of the first type.
- the claim 7 designates a particularly useful, the handling of the racket not disruptive arrangement of the actuators.
- the transverse covering can also be influenced by the configuration according to claim 8.
- a particularly advantageous embodiment of the racket is described in claim 9. Because the crossbar on the heart of the racket and! the head part has the same distance practically over the entire length, the length of the individual loops of the longitudinal covering is practically the same over the entire transverse extent of the racket, as a result of which a uniform tension and vibration behavior is achieved over the entire area of the longitudinal covering. This keeps the size of the optimal zone for hitting the ball large.
- Figure 1 shows a first racket with a rectangular frame in the cutout and partially cut
- Figure 2 shows a section II-II through the frame of
- Figure 3 shows a further racket with an approximately oval frame, cut out and partially cut
- FIG. 4 shows the frame of another racket in
- Figure 5 shows the frame of another racket with a cross covering formed from three rows of loops, in the cutout and partially cut;
- FIG. 6 shows a tensioning device for the transverse covering in the detail and in view VI of FIG. 5.
- 1 and 2 show a racket with a rectangular frame 2, which is connected via an open heart part 4 to a handle 6, on which a handle 8 is arranged.
- the frame 2 contains a transverse covering 10 made of a string 12 guided in a zigzag pattern and a longitudinal covering 14 made of a string 16 guided in a zigzag pattern.
- the loop ends 18 of the string 12 of the cross stringing 10 are suspended on each side of the frame 2 on tendons 20 of a tensioning device 22.
- Each tendon is designed as a tension string 24, which is supported on guide parts 26 of the frame 2 and which is connected to a tension spindle 28.
- the tension spindle 28 is held in a bearing 30 on the heart part 4 and carries an actuator 32 designed as a nut for adjusting the tension spindle.
- the tension string 24 contains driver stops 34, which are designed as thickened portions and against which the loop ends 18 rest. With the help of the driver stops 34, the loops are pulled over the guide parts 26 for tensioning.
- a further tensioning device 40 of the second type acts on the cross clothing 10.
- This in turn contains a tension spindle 42 with an actuator 44 and is mounted in a bearing 46 on the heart part 4 of the racket.
- the bearing 46 is preferably located on a central web 48 of the heart part 4, which lies in the longitudinal axis 50 of the racket.
- the tension spindle 42 is connected to the end 52 of the string 12 of the cross string 10 facing the heart part 4.
- the zigzag-shaped string 16 of the longitudinal covering 14 is suspended from rounded guide parts 54 of the frame 2, the guide parts 54 preferably being designed analogously to the guide parts 26.
- Both ends 56, 58 of the string 16 of the longitudinal stringing 14 are guided outwards on the crosspiece 60 facing the heart part 4 and connected to tensioning devices 62, which are of the second type.
- These tensioning devices 62 in turn each contain a tension spindle 64, which are adjustable by means of a diamond-shaped actuator 66 and are mounted in a bearing 68 on the heart part 4 of the racket. By adjusting the actuator 66, the tension of the longitudinal stringing can be adjusted, since the tension imparted via the ends 56, 58 of the string 16 continues from loop to loop via the guide parts 54.
- the racket of FIG. 3 has an oval-like frame 70 with a straight head part 72 / txnd a parallel crossbar 74 on the heart part 76, on which the handle 78 is arranged with the handle 80.
- the frame 70 contains a transverse covering 82 made of a string 84 guided in a zigzag shape, the loop ends 86 of the loops 88 in turn on tensioning members 90 of a tensioning device 92, which are provided by first type is hung up.
- the structure and arrangement of the tensioning device 92 correspond to those of the tensioning device 22 of FIG. 1, so that reference is made to the statements there.
- the longitudinal covering 94 is formed from a zigzag-shaped string 96, the loop ends 98 of the loops 100, with the exception of the crossbar 74, are guided over guide parts 102 of the frame 70.
- the loop ends 98 lying on the crosspiece are suspended from tendons 104 in the form of tension strings which belong to tensioning devices 106 of the first type.
- the loop ends 98 of each half of the longitudinal covering 94 are connected to such a tensioning device 106 of the first type.
- the latter has an actuator 103 designed as a threaded sleeve, which is rotatably arranged in a bore of a strut 105 of the heart part 72 and cooperates with a tension spindle 107.
- the loops 88 of the transverse covering 82 are intertwined with the loops 100 of the longitudinal covering 94 from left to right and from bottom to top.
- FIG. 4 again shows a rectangular frame 108 of a racket with a cross covering 110 which has a string 112 guided in a zigzag shape.
- the individual loops 114 of the transverse covering 110 are held on both sides of the frame 108 via auxiliary strings 116.
- the loops 118 of the auxiliary strings 116 are in turn on each side of the frame on a tensioning element 120 designed as a tensioning string Fixing device 122 of the first type attached.
- the latter contains a tension spindle 24 arranged in the extension of the string of the frame, which can be adjusted by means of a nut-like actuator 126.
- the tension member 120 designed as a tension string is supported on guide parts 127 of the frame 108 and bends at the attachment points of the
- Loops 118 of the auxiliary strings 116 more or less depending on the pretension set on the actuator 126 and accordingly tensions the loops 114 of the cross string 110.
- the connection between the loops 114 of the cross string 110 and the loops 118 of the auxiliary strings takes place in a mesh-like connection.
- the longitudinal covering 128 is formed by a string 130 which is guided in a zigzag shape and which is guided around guide parts 132 of the frame 108.
- the ends of the / string 130 are led out on the heart part 134 of the racket and connected to tensioning devices 136 of the racket, which are arranged on both sides of the heart part 134.
- bearings 138 are arranged on both sides of the heart part 134, in which a tension spindle 140 with a nut-like actuator 142 are arranged.
- FIG. 5 again shows a rectangular frame 144 of a racket, the cross covering 146 of which has a middle row of loops 148, the width of which corresponds to approximately half the width of the frame 144 and which is arranged symmetrically to the longitudinal axis 150 of the racket.
- Lateral loop rows 152 adjoin both sides of the middle loop row 148, the loops 154 of the middle loop row 148 meshing with the loops 156 the side rows of loops 152 are connected.
- the loops 156 of the side loop rows 152 are in turn held on tendons 158, which are designed as tension rods 160.
