Background

The present invention relates to a windscreen wiper device for connecting a wiper blade to a wiper arm according to the preamble of the independent claim.

The windshield wiper or wiper blade is connected to the wiper arm via an adapter in order to be able to assemble and replace said wiper blade on the vehicle. The adapter is usually, but not necessarily, made up of two parts connected to each other rotatably about an axis. The adapter lower part is connected to the wiper blade, in particular to a carrier structure such as a spring steel strip as a carrier element of a flat bar wiper, and the adapter upper part has a joint element for the wiper arm. In this way, a wiper blade which is fitted to the wiper arm via an adapter can adapt the inclination and curvature of the window pane relative to the wiper arm in a defined range during a wiping movement. For the connection of the adapter upper part to the wiper arm, an easily and intuitively operable and reliably maintained connection is sought, which connection can also be detached again well.

DE 102005016485 a1 discloses a device for the articulated connection of a wiper blade of a windshield wiper to a wiper arm, the device comprises a connecting element which is firmly connected with the wiper arm and a joint element which is firmly connected with a carrying element of the wiper blade, the joint element carries a bearing element, the joint element together with the bearing element forming a pivot bearing at an adapter made of plastic, wherein the adapter is fixed in the contour of the connecting element that is open toward the joint element by means of latching elements and retaining elements, wherein the connecting element is a substantially square hollow body which is open on the side facing the joint element, and at the hollow body a fastening element is formed at the longitudinal side, which covers the longitudinal side and is fastened at the end of the wiper arm.

DE 202010017492U 1 discloses a connecting device for connecting a wiper blade to a wiper arm of a windshield wiper system for a vehicle, having a connecting element which is designed to hold the wiper blade and which can be fitted to the wiper arm in a fitting direction which extends transversely to a wiper surface which can be defined by a wiping movement of the wiper blade, wherein the connecting device has at least one latching element for holding the connecting element in a positionally fixed manner at the wiper arm, wherein the at least one latching element is designed as a slider which is arranged at the wiper arm and which can be displaced along the wiper arm from a fitted state into a functional state in which the connecting element is latched. The wiper arm has at least one recess which is open in the mounting direction and is designed to receive a corresponding projection which is designed on the connecting element. The slider has at its lower end a strip with an interruption which is positioned in such a way that the corresponding projection is held in the recess in the functional state, while the projection can be pulled out in the assembly position.

Disclosure of Invention

The window wiper system with the features of main claim 1 has the following advantages: the connection of the wiper arm to the part on the adapter can be established easily and intuitively. In particular, it is not necessary to bring the stop slide into the open position for preparation. After pressing and snapping in, the window wiper device is immediately ready for use. At the same time, a secure and firm connection is obtained by the inner wall for transmitting the guiding force abutting against the side wall, in the case of a stop by the latching connection. A stop slide, for example as a sleeve which is open at the bottom, can be guided over the joint part, the stop slide being held on the joint part by a catch strip which bears locally against the lower edge of the side wall of the joint part. In the removal position, the opening or the missing section of the latching bar is then always located below the recess. The adapter upper part can be pulled out in the removal position when, in the interior of the adapter piece, which can likewise be designed as a profile that is open at the bottom, for example a U-shaped profile, the adapter upper part is located in the recess together with the latching projection. In the functional state of the locking slide, the adapter part can be pressed onto the upper adapter part until it snaps in, in that way: the inclined portion at the detent strip interacts with the inclined portion, for example likewise at the detent projection, and the inner wall or wall section of the stop slide is pressed elastically outward until the detent strip slides over the detent projection. However, it is sufficient here that: an inclination is present only at one of the two, either at the detent projection or at the detent strip.

Furthermore, advantageous refinements and improvements of the features specified in the main claim are obtained by the measures cited in the dependent claims.

It is advantageous that: the recess and the latching projection are arranged on both sides of a center plane of the adapter part and the adapter upper part, in particular symmetrically on both sides. Thereby exerting a symmetrical holding force.

In an advantageous embodiment, more than one pair of recesses and latching projections, in particular two or three pairs, is arranged. This makes it possible to achieve a very compact and short design of the adapter or of the adapter part if only one pair of latching projections or recesses is provided. However, greater redundancy, reliable retention and avoidance of tilting gaps about the transverse axis can advantageously be achieved by the pairs.

Advantageously, the joint part has a U-shaped cross section which is turned over, in particular in the form of a free end section of the wiper arm. The main element of the wiper arm is usually a metal profile. The end section of such a metal profile can thus be used cost-effectively as a joint part.

In an advantageous embodiment, the stop slider has a front transverse wall which stops the head end of the connecting piece in the functional state. As a result, the stop slide can only be pushed onto the wiper arm or the joint part up to a defined position. The defined position then corresponds to the functional state.

Advantageously, the locking slide has at least one stop, which interacts with a stop of the joint part in such a way that the locking slide is prevented from being pulled out further from the wiper arm beyond the removal position. This prevents an accidental wear of the stop slide during the removal. In the production of a window wiper system, the stop slider can be pushed and slides over the counter stop by the elasticity of the stop.

Advantageously, the stop slide consists of plastic. In particular, complex molded parts can be easily produced as injection molded parts. The desired elasticity can also be achieved by selecting a corresponding plastic.

Advantageously, the adapter upper part can be connected to the adapter lower part by means of a rotary joint, and the adapter lower part can be fastened to a carrier element of the flat-bar windshield wiper.

Detailed Description

Fig. 1 shows a window glass wiper device 1 in a perspective view. At the free end of the wiper arm 2 is a joint 3 on which a stop slide 4 is displaceably arranged in the shape of a downwardly open sleeve 5. The adapter part 3 can be placed on an adapter upper part 6, which is connected to an adapter lower part 8 via a rotary joint 7 and together with the latter forms an adapter 9. A flat-bar windshield wiper 10 with a deflector plate 11 and a carrier element not further identified here is fastened to the adapter lower part 8.

Fig. 2 shows the window wiper device 1 in a transverse section. A latching projection 12 with an upper inclined portion 13 in the side wall 19 is formed on the adapter upper part 6. The socket 3 is placed loosely on the adapter upper part 6 in the shape of a downwardly open U-shaped profile 14 together with the stop slide 4 in order to fit the socket by pressing. At the lower end, a latching bar 16 is located at the wall 15 of the stop slide 4, which latching bar covers a recess 17 in an inner wall 18 of the adapter part 3 and likewise has an inclined portion 20.

Fig. 3 shows the window glass wiper device 1 in a transverse section during pressing. When the locking slide 4 together with the adapter part 3 is pressed from above onto the adapter upper part 6, the wall 15 of the locking slide 4 is pressed outwards, as indicated by the arrow, until the locking bar 16 passes over the locking projection 12, as the inclined part 13 of the locking projection 12 passes the inclined part 20 of the locking bar 16.

Fig. 4 shows the window wiper system 1 in a functional state in a transverse section. The socket 3 rests on the adapter upper part 6 and transverse forces can be transmitted via the inner wall 18 of the adapter upper part 6, which abuts against the side wall 19. The detent lug 16 holds the detent projection 12 in the recess 17 and thus stops the adapter upper part 6 in the adapter body 3.

Fig. 5 shows the stop slide 4 in the functional state. The front transverse wall 21 adjoins the free end of the socket 3 and defines the position of the functional state. In the present embodiment two pairs of recesses 17 are used. It is also conceivable to use only one pair of recesses and thus to achieve a shorter design. The recess 17 is covered by the latching bar 16, so that the latching projection 12 is arrested when the adapter upper part 6 is inserted.

Fig. 6 shows the stop slide 4 in the disassembled state, in which the interruption 22 of the latching bar 16 is located below the recess 17. The stop 23 of the stop slide 4 interacts with the stop 24 of the joint 3, limiting the position of the removal state to the other maximum position of the displacement path and preventing the stop slide 4 from being pulled out of the joint 3.

Fig. 7 shows a further exemplary embodiment of the wiper arm 2 with the stop slider 4 and the joint element 3 in the functional state, wherein three pairs of recesses 17 are provided in this exemplary embodiment.

Fig. 8 shows an adapter 9 with an upper adapter part 6 and a lower adapter part 8, which are connected by means of a joint 7 in relation to the embodiment of fig. 7. In this embodiment, three pairs of latching projections 12 are provided.

Fig. 9 shows the stop slide 4 in the disassembled state, in which the interruptions 22 of the latching bar 16 of the stop slide 4 are located below the three pairs of recesses 17 in the socket 3, respectively.
