DESCRIPTION:
BRIEF SUMMARY
The invention relates to a string adjustment device for ball rackets, for example tennis rackets, comprising a carrier body provided with protruding engagement bodies which can be inserted matching into the meshes of the strings so that when the engagement bodies are inserted into the meshes, the strings are displaced into their correct position.
It is known that the strings of ball rackets are often displaced by the impact of the balls. Thereby for example during the stroke the direction in which the ball is thrown off is changed so that faults are caused. It is necessary therefore to replace the displaced strings into their correct position. This can be done by hand. However, such a procedure is troublesome and, over all, an exact alignment of the strings cannot be ensured thereby.
Therefore, adjustment devices for the strings of ball rackets have been already proposed (DE-OS 33 37 341, DE-GM 85 14 020). These known string adjusters consist of a plate-shaped carrier body from which tooth-shaped engagement bodies protrude. These engagement bodies are inserted into the meshes confined by the individual strings, whereby the displaced strings are replaced into the correct position.
The DE-OS 33 37 341 suggests to mount the plate-shaped carrier body either permanently at the court or clubhouse or to form it as a component of the racket covering. However, then it is not possible to use this string adjuster during the game without leaving the court or at least without a longer interruption of the game. Even if such a string adjuster is provided, the player must replace the displaced strings during the game by hand into their correct position.
The DE GM 85 14 020 certainly shows a comb-like string adjuster which due to its small dimensions can be put also in a garment's pocket and, therefore, can be used also during the game without a longer interruption thereof, however with this known string adjuster only a comparatively small number of meshes of the strings can be adjusted into the correct position in one single operation step. Therefore, it is necessary in the most cases to introduce this known string adjuster several times one after another into different meshes of the strings in order to obtain an alignment of all strings in correct position. This procedure is troublesome and time-consuming.
The present invention has at its object to provide for a string adjuster for ball rackets which on the one hand is small in its dimensions so that it can be put into a garment's pocket and therefore can be taken along during the game and can be used quickly, and on the other hand ensures a quick adjustment of all chords of the strings of a ball racket into the correct position. In order to solve this task, the invention suggests that a circulating carrier body is provided that is bearingly supported in a support member.
The dimensions of such a string adjuster can be kept small so that this string adjuster can be taken along during the game without any difficulty and, therefore, is quickly at hand so that it can be used also in short intervals of the game, for example before the service of the opponent. Nevertheless, with such a string adjuster the displaced strings of a ball racket can be brought into their correct position in a very short time, because it is only necessary to put the carrier body so onto the strings of the racket that a row of the protruding engagement bodies engages in a mesh and then to roll the carrier body along the strings so that thereby the carrier body is circulated and the engagement bodies protruding from the carrier body engage one after the other the neighbouring meshes and adjust the strings confining these meshes into the correct position.
Within a simple embodiment of the invention, the carrier body consists of a roller bearingly supported for rotation in the support member, the engagement bodies protruding from the periphery of this roller. Such a string adjuster can be manufactured very easily. In the simplest case the roller can be bearingly supported in a bow provided with a handle
