Abstract

Grip attachment for tennis racquets fitted with ventilation openings each of which is connected to a ventilation channel providing a venting system. The grip attachment is produced by an extrusion process from plastic material or by a casting process from metal. The grip is made in a pipe shape with the hollow space open at least at one end forming the ventilation channel used in common by all the ventilation openings. The ventilation channel is subdivided by stiffening elements in the form of radial stays extending along the length of the grip. The ventilation openings consist of round or oval holes of varying shape and sizes.

Reimboldweg 12. House 4 Handle for sports equipment or the like.

The invention relates to a handle for sports equipment, in particular for tennis rackets or the like

The conventional handles for sports equipment often exist made of wood, whereby wooden handles for tennis rackets are usually wrapped in old leather or a leather-like plastic material · When using this handle · is «in · disadvantageous sweating of the hand cannot be reraised This build-up of sweat means that the handle is in the hand

slips so that the sports equipment, for example the tennis racket, cannot be guided to the generally desired extent

at least the wrapping of the handle must be renewed frequently.

In order to counteract these disadvantages, it is known to wrap leather cords with holes around the handle. These leather straps absorb sweat, but they are not suitable for preventing perspiration · This will indeed prevent hot spots from developing on the grip surface delayed, but not prevented, so that after a certain time the same disadvantages in handling occur with the perforated Ledtrbander. aside from that These leather straps are subject to increased wear, as they absorb sweat.

The invention was now based on the object of providing a handle for sports equipment that can be manufactured easily and inexpensively to create, in which the disadvantages of the prior art are avoided in that directly the Sohweißbildung is counteracted

This task is achieved in a handle according to the invention for Sports equipment advantageously simply solved in that the handle is designed with ventilation openings, and that each tentilation opening communicates with a ventilating channel having a drainage channel.

BvI preventable forms of discovery Handle made of plastic or a similar easy-to-process metal, so that it is advantageously inexpensive in the iron work process tin ·· Sprits ·· or casting process

can be provided

A preferred embodiment of the invention is characterized in that the handle is tubular, and that the cavity, which is open at least at one end, forms the ventilation channel common to all ventilation openings

In a further development of the invention, the handle is in the form of a cylindrical annular space enclosing double-walled tube, in which case the at least a cylindrical annular space open at one end forms the ventilation channel

The stability of the handle according to the invention can after a development of the invention can be increased by the fact that the ventilation duct by stiffening elements is subdivided into several individual channels preferably running in the direction of the grip.

The handle according to the invention provides air circulation guaranteed, by which the perspiration of the hand is considerably reduced

The satellite ventilation openings preferably consist of round ones or oval holes, being a special good one. Circulation can be ensured that holes are different Shape and size are provided «

A suitable order τοη Löohern of different shapes and sizes looks very cheap on the desired air circulation in the sole bearing handle, so that "the desired welding preventive effect also actually is achieved.

In addition, the holes in the surface of the handle ensure a safe and comfortable grip, especially if the handle is of different shape and size. As already mentioned, the formation of soot on the hand is greatly reduced by the air circulation achieved according to the invention. It is important to note that with a tennis racket, for example, the hand is not always in the same places on the racket handle, so that there are never always the same openings in the handle area rerhindered.
