Definitions

  • the invention relates to a covering for a racket for tennis, football or the like according to the preamble of claim 1.
  • the starting point is a string of strings which are passed one after the other through the holes in the racket frame.
  • Each individual section between two holes is individually tensioned by means of tensioning devices, temporarily held until the strand is led outside over the frame into the next hole, and then released.
  • the racket is often turned over so that the tensioning device can be attached.
  • the entire string consists of one or two strings. Once the main strings have been placed and tensioned, the cross strings have to be carried out alternately above and below the main strings and also tensioned individually. Overall, this takes a relatively long time.
  • 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.
  • a prefabricated net which provides a covering as in the case of strings placed individually in the racket frame, without requiring the individual strings to be drawn in laboriously.
  • the strings for the stringing process are held in their given position with respect to one another by means of an alignment device.
  • the prefabricated net can be brought into the racket head, the free string ends being able to 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 3034 285.
  • 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 for the individual edge-side crossing points of the cross and longitudinal strings of the net can be used as a further alignment device.
  • 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.
  • the 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 network is returned to its shape to be clamped.
  • FIG. 1 shows a prefabricated covering with a first embodiment of an alignment device in a top view.
  • FIG. 2 shows a second embodiment of an alignment device for the covering of FIG. 1 in perspective and in sections.
  • 3a to 3c show a prefabricated covering with a third embodiment of an alignment device in a top view.
  • FIG. 4 shows schematically in side view a connecting element of the alignment device according to FIG. 3.
  • FIG. 5 schematically shows a side view of several connecting elements according to FIG. 4 along a rail.
  • the covering shown in FIG. 1 consists of longitudinal strings 10 and transverse strings 12 which are arranged at a distance from one another like warp and weft of a fabric in plain weave and form a prefabricated net 11.
  • the longitudinal and transverse strings 10, 12 have free, projecting ends 13 of a length such that problem-free tensioning is made possible.
  • the covering has a size which 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 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 a threading frame is inserted into the individual strings 10, 12 of the net 11 and, if necessary, until the ends of the strings are fixed and then removed again.
  • the alignment device 1 is preferably designed to be tearable.
  • the alignment device 14 is formed in a first embodiment in the form of a sheet in the form of an adhesive film which is laminated onto at least a partial area of the network, wherein a protective film can optionally be arranged on the side opposite the holder 14.
  • the alignment device 14 can be designed according to a second embodiment as a relatively flexible plastic film (or possibly plastic plate) which is provided with a network of embossed grooves 15 corresponding to the network 11 of the covering.
  • the groove 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 1 and held against falling apart.
  • a cover for the grooves 15 can also be provided here if necessary.
  • the corresponding longitudinal or transverse strings 10, 12 can be removed without further res. If the tension should be too small for a racket, an additional string 10 or 12 can also be pulled in without further. Since the main strings 1 just as the transverse strings 12 each have the same length, which is somewhat greater than the longitudinal or transverse extension of the frame, relatively short strings of string material can also be used, which leads to a better use of this material in the case of natural casing as a string material.
  • 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 should 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. However, as shown in FIG. 3a, the connecting elements 20 are preferred arranged on all crossing points 17 along the outer circumference of the network 11.
  • 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-side 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 clasping 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 rail-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 that they can be moved back and forth in order to be able to set variable distances between two longitudinal or transverse strings.
