Abstract

1. A racket, in particular a tennis racket, having a handle sleeve (3) which is able to shift longitudinally along the shank (1) of the racket and to be fixed in any position, a marking being provided for at least one position, characterized in that the longitudinal shifting and the fixing of the handle sleeve (3) is effected by means of a setting-screw (4) effective between the handle sleeve (3) and the shank (1) of the racket and that the marking extends over at least the range of adjustment (11) of the front and edge (12) of the handle sleeve (3) and is applied to the shank (1) of the racket as an impression (13) and/or imprint.

Description

DETAILED DESCRIPTION OF THE INVENTION In particular, the present invention relates to a Sugini tennis racquet having an adjustable grip shell that slides over the top of the racquet frame.

Prior Art This type of racket is based on German Utility Model No. 707.
It has been publicly known since the &/g issue. For restraining the gripping sleeve, an oval longitudinal bore is provided, the longitudinal bore extending between the gripping sleeve and the axis of the racquet at ``2'' on one side. An oval branch shaft of the bore extends in the plane of division III between the gripping sleeve and the shaft. A bottle, correspondingly oval in cross section, is inserted into this bore. By rotating the bottle to θ0, the gripping sleeve is wedged by the bottle onto the shaft. In this way, the grip is shortened from its normal length. However, this normal length is indicated by an unspecified indication.
Due to the vibrations that occur during the competition and the resulting vibrations, a gradual movement of the grip shell cannot be avoided. In this way, the short length of the grip that was adjusted for the young person is not noticeably extended towards the normal length, which prevents excessive tension in the handcuff and arm muscles. This results in the occurrence of Finally, it is also possible for the gripping sleeve to move itself completely VC away from the axis.

This is because the end 1115 position cannot be recognized. In this case, V, the Launt may be ejected from the grip sleeve during the shot, and other players, persons, or objects may be endangered or damaged.

Problems to be Solved by the Invention The present invention provides a racket of a corresponding type in which a continuous adjustment of the gripping sleeve is possible by simple means and an accidental single movement of the gripping sleeve on the axis σ). It is an object of this invention that the danger or risk of separation of the gripping sleeve from the shaft is safely prevented and thereby improved.

Furthermore, it is also an object of the invention that the intended adjustment of the gripping sleeve can be verified at any time.

Means for Solving the Problems According to a preferred embodiment of the invention, these objects are achieved by adjusting the i )i:
Through the use of the markings marked <, this is accomplished through the use of RWi screws.

The present invention has the particular advantage that it allows each player to individually adapt a racket, such as a full-sized tennis racket, to his or her sport, method of play, etc. At that time, the mark is in key 1 for the length of the grip.
It is useful as an indication.

Due to the alignment of the markings within the adjustment range of the edge of the end of the gripping sleeve, there is no special display window in the gripping sleeve.
There is no requirement that it be provided.

These and other objects, features and advantages of the present invention include:
It is believed that this will become clear from the following description, based on the accompanying drawings which illustrate embodiments thereof.

EXAMPLE The grip axis of a tennis racket is designated by the reference numeral / (the grip axis of the frame is only shown). Above the end region λ of the shaft, the gripping sleeve 3 is trapped and guided so that the sleeve 3 can be pulled longitudinally along the shaft. The position of the grip shell 3 can be changed and fixed by means of an adjustment twist, which means that the grip sleeve J and the adjustment in the threaded bore in the end of the shaft l The torsion is effected by a tongue-and-groove joint between the screw guide. However, the present invention is also applicable to a racket formed from bent metal;
In (2), the grip shaft is formed from a pair of rods or tubes corresponding to the end traps of bent metal pieces.

In such cases, a plate with threaded internal holes,
Alternatively, a block can be attached to the end of the shaft so as to function in a manner equivalent to the bore in the shaft l shown.

Tongue and groove joints (as can be seen in FIG. 7 or several flanged old means 10 that can be inserted into
be established by. Flange-shaped old means 101d,
It can also be designed as individual teeth or wall surfaces. Depending on the method of attachment, the adjusting screw can be pivoted into the gripping sleeve 3; however, the adjusting screw can be screwed into the gripping sleeve 3. By screwing the adjusting screw into the internally threaded hole S and unscrewing it from the hole S, the gripping sleeve 3 can be moved longitudinally with respect to the axis l of the , the length of the racket grip can be adjusted.

In the adjustment area // near the top edge 1.2 of the gripping sleeve J, an indicia /J (made by engraving, embossing, printing, embossing, tagging, etc.) is located on the shaft. The upper Yc of l is provided, and this 1:11/J is more or less covered by the grip sleeve 3 depending on the adjustment position 11 of the grip sleeve 3. Advantageously, the lateral 8/11. , are preferably provided in order to obtain a clearer indication of the adjusted position of the gripping sleeve 3.The mutual spacing of the crossbars is conveniently /-3 mfll, and the crossbars/grips are preferably As shown in the mt diagram, the length of pJ can be decreased sequentially.

The markings 13 are also conveniently used to indicate the balance, i.e. the distribution of weight, or the movement of the center of gravity of the racket.
can also be used. Therefore, as a sign of balance or weight, e.g. "low" from top to bottom;
For “Low/Moderate” and “Moderate J”, L, LM and M
It can also be used in its entirety.

The mark /3 may be rectangular or square, or wedge-shaped or arrow-shaped as shown in Figure 1, or may have a double wedge shape according to Figure 3. Also in this configuration, the two wedges 7.1 and /A are preferably arranged with their major sides facing each other, thus combining to form a rectangle. It is desirable to create - opposing (l

Additionally, the ink stamp inside the enclosed mark (
formed by engraving or embossing] has the advantage that it does not wear out very quickly.

Although the main field of application of the invention relates to tennis racquets, the invention is also advantageous in the case of other types of racquets, such as Scots rackets, badminton racquets, racquetball racquets, etc. It is something that can be used for.

Although the illustrated and described embodiment relates to the use of a gripping sleeve 3 formed from only one tubular piece, the stamped adjustment position guide 13 can also be used with a 7983
