"Bats for ball games"

The invention relates to a racket for ball games according to the preamble of claim 1. Based on a prior art, as described in the main application P 33 27 625.0, is the invention is based on the object of creating further possibilities in a racket of the type specified at the beginning, by which the sweat training in the hand of the player is prevented or reduced respectively. of welding training is counteracted.

To solve this problem, the feature of claim 1 is proposed.

By arranging a hollow profile piece, which around the handle is placed, it is no longer necessary to make the handle itself hollow, but it tennis rackets from previous production can be provided with such ventilation, by attaching a hollow profile piece directly to the handle, which profile piece then possibly from a perforated grip tape or the like can be surrounded radially on the outside.

The ventilation takes place in that air is drawn in through the air passage opening provided axially at least on one side the radially outwardly open air passage openings can be introduced, whereby the movement of the player's hand creates a kind of pumping effect, which leads to a circulation of air, which is executed to the palm of the player.

The feature of claim 2 is proposed in a further development.

The profile piece can, for example, consist of an extruded plastic profile or a metal profile be educated.

The chamber-like design is used to stiffen the profile piece, so that it is usually when playing tennis or the like can withstand pressure loads.

The individual chambers of the profile are through to each other Air vents connected so that air circulation overall is not disturbed by the chamber training.

"Bats for ball games"

The invention relates to a racket for ball games according to the preamble of claim 1. Starting from a state of the art, as it is in the Main application P 33 27 625.0 is described, the invention is based on the object of further possibilities in the case of a racket of the type specified at the outset, through which the sweat training in the hand of the player is prevented or reduced respectively. the sweat training is counteracted.

To solve this problem, the feature of claim 1 is proposed.

By arranging a hollow profile piece, which around the handle is placed, it is no longer necessary to make the handle itself hollow, but it tennis rackets from previous production can be provided with such ventilation, by attaching a hollow profile piece directly to the handle, which profile piece then possibly from a perforated grip tape or the like can be surrounded radially on the outside.

The ventilation takes place in that air is drawn in through the air passage opening provided axially at least on one side the radially outwardly open air passage openings can be brought in, whereby by the movement the player's hand creates a kind of pumping effect, which leads to air circulation to the palm of the hand of the player is executed.

The feature of claim 2 is proposed in a further development.

The profile piece can, for example, consist of an extruded plastic profile or a metal profile be educated.

The chamber-like design is used to stiffen the profile piece, so that it is usually when playing tennis or the like can withstand pressure loads.

The individual chambers of the profile are through to each other Air vents connected so that air circulation overall is not disturbed by the chamber training.

A further development is described in claim 3. Through the appropriate design of the air passage openings large-area air circulation can be achieved.

As an alternative or in combination, this task is carried out with the feature according to the characterizing part of the claim 4 solved.

In this case, a fan blade with a drive motor is used to generate an air flow inside the hollow handle piece and accumulator, for example arranged in the form of a battery.

The accumulator makes contact in a known manner, as is customary in the case of flashlights, for example can be connected to the electrical connections of the drive motor.

When the fan blade is started up, air is drawn into the Cavity sucked in through the air passage openings and released again through further radially outer openings in the handle.

This creates air circulation at the hand of the den The player holding the racket produces a reduction in perspiration in the hand of the Player.

A further development is referred to in claim 5. A preferred further development is in claim 6 designated.

Embodiments of the invention are shown in the drawing shown and described in more detail below. It shows:

1 shows a handle designed according to the invention Tennis racket in longitudinal section;

Fig. 2 also seen from the front, in perspective.

FIG. 3 shows a variant according to FIG. 1.

The tennis racket consists essentially of a frame 1 in the part of interest here Drawing is only hinted at. This predominantly has a molded handle 2, which can be wrapped with a grip tape.

The handle 2 is surrounded radially by a hollow profile piece 3, which is open radially outward Has air passage openings 4.

At least on one side, in the exemplary embodiment on both sides axially there is a further air passage opening provided in the form of an annular channel.

Grizina 8202/83 ο q O c O /

Through the front air passage opening 5 air can enter the hollow profile piece 3 and exit again through the openings 4, so that the Hand of the player being ventilated.

Likewise, air can enter or through the opening 5 on the side facing away from the end face step out.

The profile piece 3 can, for example, consist of a profile made of plastic that has a plurality of chambers or metal, which chambers are connected to each other by air passage openings, so that a continuous air flow can be achieved.

In Figure 2 it can be clearly seen that the profile piece reaching through at least radially on the outside Air passage openings 4 formed like a slot are.

According to the embodiment of FIG. 3, the handle 2 is hollow.
It is also open at the front.

An electrically drivable fan blade 7 is rotatably mounted in the cavity 6.

Furthermore, the drive motor 8 for the fan blade and the power supply for is in the cavity 6 the motor in the form of an accumulator 9 is supported.

The accumulator is provided with a spring 10 cover part 11 in the manner with the Motor connected in an electrically conductive manner, as is known, for example, from flashlights.

The cavity 6 stands over channel-like air passage openings 12 with a cavity 13 formed between the handle piece 2 and a profile piece 3 surrounding it Link.

The profile piece 3 in turn has openings 4 which are open radially outward.

Finally, the end of the cavity 13 opens into an annular channel 14.

The air passage openings 12 are on the suction side of the fan blade 7 arranged converging, while further air outlet openings 15 on the pressure side of the fan blade 7 are arranged.

In this way, when the fan blade is operated an air circulation is achieved, after which the air enters through the annular channel 14 into the cavity 13 the openings 4 can escape, finally the excess is brought through the openings 12 to the fan blade and from the openings 15 again from the cavity can be removed.

This measure is also particularly suitable for ventilating the hand of a tennis player or the like.

The invention is not limited to the exemplary embodiments limited, but often variable within the scope of the disclosure.

All new individual and combination features disclosed in the description and / or drawing are used regarded as essential to the invention.
