Embodiment Construction

[0025] figure 1 A partial view from the side of the wiper arm and the drive shaft 1 is shown, wherein the drive shaft 1 is inserted into the opening of the wiper arm 3 . The wiper arm 3 and the shaft 6 are shown in section. The cylindrical drive shaft 1 has knurling 2 at the end. A clamping element 4 and a further clamping element 5 are accommodated in this opening. The clamping element 4 can also be mounted above and below the opening of the wiper arm 3 . However, this would lead to a thickening of the wiper arm 3 . The clamping element 4 is arranged rotatably about an axis 6 , while the clamping element 5 is fixedly seated in an opening of the wiper arm 3 . As an alternative to the further clamping element 5 , a clamping element which is also rotatably fixed can also be used.

[0026] The rotatable clamping element 4 has an oval cross-section. If the rotatable clamping element 4 is to be rotated in the direction of the arrow, the distance from the rotatable clamping el...

Abstract

The present invention relates to a wiper having a wiper arm (3) which has an opening into which a drive shaft (1) can be plugged, wherein a clamp-in element (4) is fitted in a rotatable manner in theopening, wherein an axis of rotation is defined by the rotation of the clamp-in element (4), and wherein the spacing between the axis of rotation and the surface of the clamp-in element (4) changes along a circumference of the clamp-in element (4). Such a wiper allows precision alignment, which is not restricted by knurling in an opening of the wiper arm.

Description

technical field [0001] The invention relates to a wiper, in particular a vehicle wiper, and to a corresponding method for fastening the wiper. Background technique [0002] Various windshield wipers are known from the technical background, which are fastened on a drive shaft, the cylindrical end section of which is provided with knurling. The wipers each have a wiper arm in which an opening is provided and the opening is provided with knurling. For fastening, the wiper provided with the opening is mounted on the drive shaft such that the knurling on the cylindrical end section of the drive shaft engages with the knurling provided in the opening of the wiper arm. The wiper can thus be non-rotating relative to the drive shaft and can follow the motion of the drive shaft. [0003] During processing, it is hoped that the specific parts of the wiper will be standardized to a large extent, so that such wiper can be used on a variety of different cars. The orientation of the wip...
