The invention relates to a bridge for a ball game racket as well as to a frame for a ball game racket comprising a bridge.

Bridge for a ball game racket

The present invention relates to a grommet strip for a racket for ball games, wherein the grommet strip comprises a longitudinal direction and a plurality of grommetscomprising grommet through-holes, wherein each of the grommetsdefines a grommet axis A and each of the grommet through-holesdefines a hole axis B, wherein the grommet axes A and the hole axes B extend substantially parallel to each other and wherein the hole axes B of some grommets are offset with respect to the grommet axes A thereof in the longitudinal direction of the grommet strip.

Grommet strip

The present invention relates to an elastic grip sleeve for the grip of a ball game racket, the sleeve having an inner surface and an outer surface, wherein the inner surface is provided at least in parts with an adhesive strip. The present invention moreover relates to a retrofit kit for a ball game racket, comprising a grip sleeve and at least an adhesive strip. Moreover, according to the invention there is provided a method for attaching a grip sleeve to the grip portion of a ball game racket.

Elastic grip sleeve and grip cap for ball game racket

The invention relates to a racket for ball games, in particular a tennis or squash racket, comprising a head region for receiving a stringing as well as at least one joint which is provided in the head region and the joint axis of which is arranged essentially perpendicularly with respect to a stringing plane formed by the stringing.

Racket comprising a joint

A ball game racket according to the present invention comprises a racket head and a racket shaft, wherein the racket head comprises a stringing having transverse strings and longitudinal strings each having a vibration length. The racket head comprises a means which reduces the vibration length of a plurality of strings on both sides of the stringing depending on the deflection of the strings. The means is attached as a separate part to the racket head.

Ball game racket with variable vibration length

The disclosure relates to a racket for ball games, and in particular, a tennis or squash racket, with a head region for receiving a stringing defining a stringing plane, a grip portion for holding the racket, and a heart region wherein the heart region has two arms and a bridge. The bridge may be pivot-mounted on both arms relative to an axis substantially perpendicular to the stringing plane. The present disclosure further relates to a method for manufacturing a racket including the step of manufacturing a racket frame with a head region, two arms, and a grip portion in a blow molding process. The method may also include manufacturing a bridge for a racket frame in the blow molding process. The method may further include connecting the bridge with the remaining racket frame.

Racket with moveably mounted bridge

A racket for ball games may include a frame which is formed by a frame profile or a hollow profile and has a racket head and a handle portion connected thereto preferably via a heart region. Two indentations that are symmetrical relative to the longitudinal axis of the racket may be provided in the heart region of the frame. A vibrating device may be arranged in each of the two indentations. The vibrating means of the racket may preferably be effective for vibrations having at least two vibration modes or degrees of freedom. Additionally or alternatively, a racket for ball games may include a frame which forms a head region for receiving strings and a handle portion for holding the racket. The frame may include one respective inwardly-facing C-profile in at least two segments of the head region.
