"Handle for tennis rackets and associated tennis rackets"

The invention first relates to a handle for tennis rackets according to the preamble of claim 1. Such handles are from DE-GM 76 18 600 and the DE-OS 25 14 059 known. In these two previous releases are groove-like recesses of the handle surface by extending in the radial direction to the inside of the handle Openings connected to the hollow inside of the handle. The hollow Griffinnsre opens at the one facing away from the racket Forehead detj grip into the open. The other end the inside of the handle is screwed to the racket with a screw. This is intended to be the result of playing Hand perspiration or perspiration fumes can be dissipated through the hollow inside of the handle. This design of the handle requires that its screw fastening on the bat between this and the hand holding the handle lies. As a result, when playing, such strong forces or moments occur on this screw

* ■ fastening on that they usually meet these loads

I cannot withstand j at least after a certain amount of play

i time breaks.

; The object of the invention is therefore, starting from the upper

5 concept of claim 1, seen therein, a flawless ι Ventilation or removal of the hand-

^r 'sweat together with one in the attachment to the tube

ger stable and simple and thus inexpensive design of the handle.

To solve this problem, the features of the characterizing part of claim 1 are initially used. The longitudinal recesses and
the transverse recesses take up the sweat or perspiration fumes via the holes in the band and lead it to the outside via the open front openings of the longitudinal recesses.

15 The arrangement according to the invention of the longitudinal and transverse recesses gene allows the provision of an inner bore known per se

j in the handle, with which he moves over the shaft part of the racket

] can be postponed. This is an absolutely stable

j fixation of the handle on the shaft part of the racket. Of the

1 20 handle according to the invention can cost-effectively made of plastic, fabric made, preferably sprayed weirdon.

The features of claim 2 are both manufacturing technology simple, as well as cheap in terms of sweat removal. the The aforementioned advantages are further improved by the features of An-25 Spruches 3.

A particularly advantageous and preferred embodiment the invention results from the features of the claim

. Q-

4. The cross-section of the grooves in the shaft part is larger as the largest possible cross-section of a longitudinal recess on the surface of the handle. So there is a bigger one Cross-section available for the removal of sweat or sweat fumes. In addition, this groove cross-section " is open towards the racket and thereby hurled sweat in it forward during the hitting process will. Another advantage is that with the implementation of the transverse recesses up to the inner surface of the handle Material is eliminated and the grip becomes easier.

Claim 4 is further developed with the features of claim 5.

With the spraying of the handle is easy too

to realize the feature according to claim 6, which

the attachment of the perforated tape is made much easier.

The features of claim 7 include an advantageous possibility of combining the features of the preceding Expectations.

The already mentioned task area of reduction the manufacturing costs also relates to the connection of such a handle to the shaft of the racket. To solve this part of the task, the Features of claim B proposed, which can be further developed by the features of claims 9 and 10. The cost savings with a cäeser connection between manual

handle and club shaft part is opposite to previously known Connection types very large. In addition, such a way of connecting the removal of sweat or Welding fumes according to the preceding claims do not interfere or hinder, even if this takes place via the groove / Ses shaft part.

Further details emerge from the exemplary embodiments of the invention explained below and shown in the drawing. In the drawing shows:

The racket 1 consists of the actual one with the covering provided racket part 2 and the shaft part 3, via which the handle, which is only indicated schematically in FIG. 1 4 is pushed. The attachment of the handle 4 on the shaft part 3 is preferably carried out in such a way that the Handle 4 made of a plastic with a relatively high coefficient of thermal expansion, preferably injection molded is, and by thermal shrinking on the Shank part 3 is held on it. For this purpose, the handle 4 can be made of a plastic from the polyethylene group be injected, e.g. B. polyethylene or polypropylene. The use of a plastic from Medium Shore hardness or elasticity, since a plastic that is too soft does not hold tight enough to the shaft part, on the other hand If the plastic is too hard, the impact stresses coming from the racket are almost undamped when playing passes to the player's hand.

To the handle 4 is a in Fig. 1 for a clearer distinction Dotted lines, made of leather or plastic tape 5 wrapped with holes or Punchings 6 is provided, of which only two are shown to simplify the drawing. The end of the tape can be clamped in a slot (not shown in the drawing) on one of the handle ends 7 and 8, respectively will. The tape can then be wound around the handle 4.

In the embodiments of FIGS. 2, 3 and 4, 5 is only for reasons of simplified graphic representation

- Sr -

The band 5 is omitted. In reality, however, in the finished racket it is wrapped around the handle 4, as is is shown in FIG. Furthermore, in Fig. 2,

and 4, 5 of the shaft part 3 for graphic differentiation

4 '
dung from the handle 4, / each shown in phantom. Of the

_; Handle 4 according to the example of FIGS. 2, 3 has around

circumferential transverse recesses 9, of which only a few are shown and their plane here transverse to the longitudinal axis

10 of the handle runs. Longitudinal recesses 11 are provided parallel to the longitudinal axis 10 ″ 10, which are likewise

like the transverse recesses 9 extend in the manner of grooves from the surface ■ of the handle 4 inward and coincide with it

the transverse recesses 9 cross at right angles. The bridge parts remaining in between are numbered 12.

The longitudinal recesses 11 - in this embodiment

two of these longitudinal recesses are shown - end with - at least one of their end openings 13 on one of the handle ·. ' ends 7 or 8 open, ie outdoors, so that the

j - perspiration or perspiration fumes and fresh air

can enter the longitudinal recess 11 and from this can reach all or part of the transverse recesses 9.

: It goes without saying that the number and arrangement of the longitudinal recesses 11 and / or the transverse recesses 9 may also be different can, as shown and described in this embodiment. It is only essential that the transverse recesses open into one or more of the longitudinal recesses

11 and that one or both ends of the longitudinal recesses 11 are open to the outside.

The cross-sections 4 of the handle part shown in FIG. 3

/ ö-

are on the webs 12 and also the front and rear Grip areas 7 ', 8' connected to one another. FIG. 3 also shows how the handle 4 is pushed over the shaft part 3 is.

Finally, FIGS. 2, 3 show the above-mentioned preferred embodiment of the invention, which is intended for sliding the handle onto shaft parts in the narrow side walls of which there are grooves 14 running in the longitudinal direction. In the adjoining longitudinal ^{section y e} f5 of the handle 4, the transverse recesses are

* ) mungings carried out up to the inner handle surface 16, the cross-section of the grooves 14 is left free of grip material, at least over the substantial length range of the handle 4, and the grooves 14 'are open to the outside with their end faces 14' facing the racket part 2. They therefore have the function of longitudinal recesses serving ■ for welding ventilation. According to the preferred embodiment of FIGS. 2, 3, they are provided in combination with the longitudinal recesses 11 already explained.

In the end 7 'facing away from the racket part 2, relatively short folds can be provided which into the ends there the grooves 14 fit and serve to provide additional hold between the handle 4 and the shaft part 3, in particular in terms of shape an anti-twist device.

FIGS. 4, 5 show a simplified embodiment with " a handle 4 '. With the example of FIGS. 2, 3 the same

Components are numbered the same here. In this exemplary embodiment, there is no air connection between the side sections 15 and the grooves 14. Rather, only the two longitudinal recesses 11 are used here for venting to the outside. The grooves 14 extend over their entire length from
the folds 17 of the handle 4 'filled.

All features shown and described, as well as
their combination with one another are essential to the invention
