Definitions

  • the invention relates to a covering for a racket for tennis, badminton or the like according to the preamble of claim 1.
  • the object of the invention is therefore to provide a covering according to the preamble of claim 1, which is suitable for any racket frame and considerably simplifies the work process when covering.
  • the strings for the stringing process are held in their predetermined position with respect to one another by means of an alignment device.
  • the prefabricated net can be brought into the racket head, and the free string ends can be guided through the respectively associated holes in the racket frame.
  • the strings can then be tensioned individually or in groups. No forces are transmitted to the frame itself until it is covered, which means that the frame is not deformed.
  • the individual strings in the tensioned, state are fixed in the holes in the frame, for example by means of a wedge arrangement, as is known from DE-OS 30 34 285. After the tensioner has been released, the protruding string ends are cut off and the alignment device is preferably removed, provided that it has not detached itself.
  • An adhesive film can be used as an alignment device for the strings, which extends at least over a partial area of the net and adheres there to the strings.
  • a plastic film or plate with a groove network that receives the strings can also be provided as the alignment device.
  • a fixing device can be used for the individual edge-side crossing points of the cross and longitudinal strings of the network.
  • connecting elements for example grippers, that can be placed on the crossing points can be provided. With these grippers, additional positional fixation of the crossing points can be achieved by lining up the grippers along a rail.
  • four rails linked via their corner points are provided for the four sides of the network.
  • the fixing of the intersection points on the edge can also be achieved by means of inserted threads in the manner of a hem, this hem being easily removable when a thread is severed.
  • Such an alignment device fixes the predetermined position of cross and main strings even with compression and / or extension of the prefabricated net, which simplifies packaging or storage of the net. After this temporary deformation, the alignment device ensures that the laid net is returned to its shape to be clamped.
  • the covering shown in FIG. 1 consists of main strings 10 and cross strings 12 which, like warp and weft of a fabric in plain weave, are arranged at a distance from one another and form a prefabricated net 11.
  • the main and cross strings 10, 12 have free, outwardly projecting ends 13 of a length such that problem-free tensioning is made possible.
  • the covering has a size that can be adapted to the different racket sizes and can be produced inexpensively on machines similar to wire weaving chairs.
  • An alignment device 14 is provided at least in a part of the area in which the longitudinal strings 10 and the cross strings 12 cross (cf. also FIGS. 2 and 3). This alignment device 14 preferably remains until the individual strings 10, 12 of the net 11 are threaded into holes in a racket frame and optionally until the string ends are fixed, in order then to be removed again.
  • the alignment device 14 is preferably designed such that it can be torn off.
  • the alignment device 14 is flat in the form of an adhesive film which is laminated onto at least a partial area of the network, it being possible for a protective film to be arranged on the side opposite the holder 14.
  • the alignment device 14 can be designed as a relatively flexible plastic film (or possibly a plastic plate) which is provided with a network of embossed grooves 15 corresponding to the network 11 of the covering.
  • the grooves 15 have a width corresponding to the width of the main and cross strings 10, 12 and a depth at least equal to twice the strength of the main and cross strings 10 and 12, so that the clothing is completely absorbed by the grooves 15 and held against falling apart.
  • a cover for the grooves 15 may also be provided here, if necessary.
  • the alignment device 14 can comprise attachable spacer pieces, which are provided, for example, on a circumferential ring.
  • these spacers are designed as connecting elements 20 which are placed on individual edge-side crossing points 17 of the strings 10, 12 in order to fix their relative position by pressing the strings 10, 12 together in the respective crossing point 17. In particular, this is intended to prevent fraying and / or slippage of the strings 10, 12 which destroys the network.
  • the connecting elements 20 can only be placed scattered on individual crossing points 17 in the edge region of the network 11, but then preferably in the corner regions 18 of the network 11 according to FIG. 3b. As shown in FIG. 3a, however, the connecting elements 20 are preferably located on all crossing points 17 along the The outer circumference of the network 11 is arranged.
  • the connecting elements 20 are preferably linked to one another, in particular along one side of the network 11, so that the selected relative position of the edge crossing points 17 can be retained even after the network 11 has been deformed.
  • the connecting elements 20 are lined up along a rail 30, which spatially defines the position of the connecting elements 20 with respect to one another, which is preferably done with a play of movement.
  • FIG. 4 shows an embodiment of an individual connecting element 20, which is designed as a gripper that clasps the respective crossing point 17.
  • This gripper comprises a head part 21, on which arms 22 are resiliently formed.
  • the head part 21 is preferably formed with a neck 23 of smaller diameter, which enables the grippers to be hooked into the rail 30.
  • the number of arms 22 is at least two, but preferably four.
  • the arms 22 are arranged at a distance from one another, in such a way that a string 10, 12 of different thickness can be passed between two arms 22.
  • the arms 22 are each directed towards one another Hook 24 equipped. These hooks 24 enclose a gripper chamber 25.
  • FIG. 5 shows the connecting elements 20 described above, which are suspended at a distance from one another in a strip-shaped rail 30.
  • the rail 30 has openings 31, the diameter of which is smaller than the diameter of the head part 21 but larger than the diameter of the neck 23.
  • the connecting element 20 is spatially fixed within the recess 31, but with a play of movement.
  • the openings 31 are arranged along the rail 30 at intervals corresponding to the selected distances between two longitudinal or transverse strings 10, 12.
  • the connecting elements 20 can be guided in the manner of hanger rollers in a rail so as to be able to be locked and pushed back and forth in order to be able to set variable distances between two longitudinal or transverse strings.
