Technical Field

The present invention relates to a window panel wiper according to claim 1. The invention is characterized in that the dependent claims are dependent on the invention. It is to be noted that the features and measures listed individually in the following description can be combined with one another in any technically meaningful way and represent further embodiments of the invention. The invention is additionally characterized and explained in detail in the description, particularly with reference to the figures.

Disclosure of Invention

It is proposed that a windshield wiper be provided, which comprises a wiper blade and a wiper arm, on which the wiper blade is arranged. The wiper arm is designed in the form of a cap and has a fastening point for the wiper blade within the cap-shaped structure thereof. A nozzle element is arranged inside the wiper arm, which nozzle element sprays liquid alongside the wiper blade in the direction of the window pane. The window wiper cleans a window plate on which the wiper blade is placed. The wiper blade can be placed in a fixed position, preferably by means of an adapter. The proposed windshield wiper design achieves a space-saving solution, which moreover provides the windshield wiper with a nozzle element for a windshield wiping fluid in a cost-effective manner.

Advantageously, a channel section of the nozzle element can be arranged on both sides next to the wiper blade, wherein the channel sections are connected to a common delivery device. Thereby, liquid is applied to the window pane in the wiping direction immediately in front of and/or behind said wiper blade.

The nozzle element can be composed of at least two parts, at least one of which is perforated and is connected to the second part in a watertight manner. It can be glued and/or welded. The extrusion can be carried out using an ultrasonic welding method and/or a laser welding method and/or by means of a heated punch.

Channels are formed in the nozzle element, through which channels liquid is guided. The perforations in the nozzle element merge into the channel, so that liquid can be ejected from the channel through the perforations. The channel comprises at least one channel section, which is formed by two composed parts.

The perforations are formed by holes which are directed in different directions, in particular, so that the liquid sprayed out through the holes in the direction of the window panel appears as mutually divergent spray jets. The spray then impinges on the louvers at different locations along the length of the wiper blade. The holes can be formed by channels that are oriented in different directions so that the spray diverges. Alternatively, the jet can be deflected in different directions by means of a spherical nozzle.

The channel section can be formed by a half-shell-shaped component to which a plate-shaped component is welded, preferably by an ultrasonic method. The plate-like member can comprise perforations. Thereby providing an easily designed channel.

The nozzle element can be flattened on the side facing the wiper blade. This prevents the nozzle element from protruding from the interior of the wiper arm in the direction of the wiper blade.

It is particularly preferred that the nozzle element is arranged flush with the lower edge of the wiper arm. The nozzle element thus does not project from the edge in the direction of the wiper blade and can laterally fill the gap between the edge and the nozzle element in such a way that the nozzle element preferably rests on the edge.

It can be provided that at least one section is u-shaped. The nozzle element can be generally u-shaped or o-shaped.

Preferably, the nozzle element can enclose a fastening point for the wiper blade, so that the fastening point can be accessed from the outside. Such a nozzle element surrounds the fixed position. In particular, the u-shaped or o-shaped nozzle element can at least partially surround the fastening point.

In order to be able to advantageously guide the liquid to the nozzle element, the conveying device can be arranged substantially centrally on the nozzle element.

Detailed Description

Fig. 1A shows the underside of the windshield wiper 10. The windshield wiper 10 includes a wiper blade 12 that is mounted on a wiper arm 14. The wiper blade 12 is fixed in a fastening position 15, wherein an adapter preferably used for this purpose is provided on the wiper blade 12. The windshield wiper 10 wipes the windshield on which the wiper blade 12 is placed and cleans the windshield by a wiping movement. The wiper blade 12 extends along a wiper arm 14.

The wiper arm 14 is formed in the shape of a cap by a preferably injection-molded part which opens out in the direction of the wiper blade 12 or the windshield. The fastening position 15 is arranged in the wiper arm 12 and is accessible through an opening of the wiper arm 14. The opening is surrounded by an edge 26, which represents a free standing edge in the direction of the wiper blade 12.

In the wiper arm 14, a nozzle element 16 is arranged, which comprises a receptacle 17, into which receptacle 17 the fastening point 15 is arranged. The nozzle element 16 is flush with an edge 26 of the wiper arm 14, so that the nozzle element 16 does not project beyond the edge 26 in the direction of the wiper blade 12. The component 22 with the perforations 23 is directed toward the wiper blade 12, so that the liquid is sprayed through the perforations 23 in front of and beside the wiper blade 12 with respect to the wiping movement direction.

The nozzle element 16 of fig. 1A has a section 25 which is o-shaped. The section 25 surrounds the receptacle 17 for the fixing location 15. In this case, a part of the bore is positioned in front of the fastening point 15 and a part is positioned behind the fastening point 15, wherein between these two parts a delivery device 20 for the liquid is arranged on the nozzle element 16. The conveyor device 20 extends in the longitudinal direction of the wiper arm 14 and is connected to a hose 30.

The perforations 23 are arranged in a row along the longitudinal direction of the wiper arm 14 by means of holes. The two parts of the o-shaped section 25 which have the perforations 23 extend in the longitudinal direction of the wiper blade. The adapter of the wiper blade 12 is inserted through the receptacle 17 of the nozzle element 16, so that it is surrounded by the nozzle element.

Fig. 1B shows a wiper arm 14, at which a u-shaped nozzle element 16 is mounted. The receptacle 17 is surrounded by the u-shaped nozzle element 16. The two elongated, perforated parts of the u-shaped section 25 form a fork-shaped structure, the free ends of which are oriented in the longitudinal direction of the wiper arm. The fixing location 15 is not completely surrounded by the nozzle element.

Fig. 2A shows an o-shaped nozzle element 16 that can be assembled from two parts 22, 24. The first part 23 in fig. 2AI is plate-shaped and likewise has an o-shape. It comprises perforations 23. The contoured second part 24 comprises a channel 19 with a channel section 18, which is likewise o-shaped and is connected to the conveying device 20. The first component 22 is placed on and fixedly welded to the second component 24.

Fig. 2B shows the nozzle element 16 assembled as in fig. 2A, wherein it is u-shaped and has a fork-shaped structure.

Fig. 3 shows an articulated section of the wiper arm 14, which is attached to a rotation point of a windshield wiper system. In the region of the joint section which is arranged at the axial end of the wiper arm, a recess 28 is formed through which a hose 30 of the nozzle element 16 can be passed. The recess 20 is formed in the edge 26 and opens in the direction of the wiper blade. The hose is led out of the wiper arm through the recess 28.
