Document DE 10 2007 058 091 A1 has already disclosed a wiper blade adaptor device, in particular for a wiper blade of a motor vehicle, comprising a wiper blade adaptor and a coupling element for coupling the wiper blade adaptor to a wiper blade.
The invention is based on a wiper blade adaptor device, in particular for a wiper blade of a motor vehicle, comprising a wiper blade adaptor and a coupling element for coupling the wiper blade adaptor to a wiper blade.
It is proposed that the wiper blade adaptor is connected releasably to the coupling element, as a result of which the wiper blade adaptor device can be designed to be fitted and/or to be interchangeable in a particularly simple manner. In this context, a “wiper blade adaptor” is intended to be understood in particular as meaning an adaptor which is provided so as to provide a coupling region of the wiper blade adaptor device for coupling to a wiper arm. In this context, a “coupling element” is intended in particular as meaning an element which is provided to couple the wiper blade adaptor to a component of a wiper blade, such as, in particular, to a strip-shaped carrier element. In this context, “releasably” is intended to be understood in particular as meaning “non-destructively separable”. Particularly advantageously, the wiper blade adaptor is releasable and/or fastenable without a tool. In this context, “provided” is intended to be understood in particular as meaning specially configured and/or equipped.
If the coupling element has at least one latching means which is provided so as, in a fitted state, to form a form-fitting connection to the wiper blade adaptor, a low-wearing connection which is simple to release can be produced between the wiper blade adaptor and the coupling element. In this context, a “latching means” is intended to be understood in particular as meaning a means which is provided to produce a latching connection by means of a spring-elastic component which is elastically deflected for installation.
If the latching means is arranged at a free end of the coupling element, the coupling element can be formed particularly stably. In this context, a “free end” is intended in particular as meaning one end of a main longitudinal extent of an element. A “main longitudinal extent” in this context is intended to be understood in particular as meaning as large an extent as possible. In this context, an “extent” of an element is intended to be understood in particular as meaning a maximum distance between two points of a vertical projection of the element onto a plane.
The wiper blade adapator can be fitted particularly simply and securely if the coupling element has a longitudinal guide unit which is provided to guide the wiper blade adaptor upon a pushing-on movement during installation. In this context, a “longitudinal guide unit” is intended to be understood in particular as meaning a unit which is provided so as to provide guidance of a carrier element in a longitudinal direction. In this context, a “longitudinal direction” is intended to be understood in particular as meaning a direction which extends at least substantially parallel to a main longitudinal extent of the carrier element. In this context, “substantially” is intended as meaning in particular a deviation of less than 10°, preferably of less than 5°. In a further refinement of the invention, it is proposed that the longitudinal guide unit has at least one longitudinal guide element which is formed in one piece with a basic body of the coupling element, as a result of which the wiper blade adaptor can be stably fixed. In this context, a “longitudinal guide element” is intended to be understood in particular as meaning a guide element which extends at least substantially parallel to a longitudinal direction of the coupling element. “In one piece” is intended to be understood in particular as meaning integrally bonded, for example by a welding process and/or adhesive bonding process, etc., and particularly advantageously as meaning integrally formed, such as through production by casting and/or production in a single- or multi-component injection molding process.
Furthermore, it is proposed that the latching means is deflectable substantially perpendicularly to a supporting surface of the coupling element, thus enabling a secure configuration to be achieved.
In a further refinement of the invention, it is proposed that the latching means has at least one spring means which closes off the coupling element in a longitudinal direction, as a result of which the coupling element can be formed particularly stably.
Furthermore, it is proposed that the wiper blade adaptor has an extension which, in a fitted state, forms a form-fitting connection to the latching means. As a result, the latching means can bear against a particularly large contact surface.
Further advantages emerge from the description below of the drawing. The drawing illustrates an exemplary embodiment of the invention. The drawing, the description and the claims contain numerous features in combination. A person skilled in the art will expediently also consider the features individually and put them together to form meaningful further combinations.
The wiper blade adaptor 10 is connected releasably to the coupling element 12. Non-destructive separating of the wiper blade adaptor 10 from the coupling element 12 is therefore possible. The coupling element 12 is fixedly arranged on the wiper blade 14 in a manner known to a person skilled in the art.
As
The spring means 38 is formed in one piece with the latching means 18 and the coupling element 12 and has a rounded portion 50 at which particularly high elastic deformation by the latching means 18 is made possible.
The rounded portion 50 rotates the spring means 38 in an unloaded state through 170°. If the latching means 18 is pressed toward the spring means 38, the rotation of the spring means 38 is increased. As a result, the latching means 18 can be elastically deflected perpendicularly to the supporting surface 32 from a starting position.
Furthermore, the coupling element 12 has a longitudinal guide unit 24. The longitudinal guide unit 24 comprises two longitudinal guide elements 26 which are formed in one piece with the basic body 28. In this case, the longitudinal guide elements 26 form a part of opposite side walls 30 of the basic body 28. The longitudinal guide elements 26 form a lower edge 40 of the basic body 28 which serves as a bearing for the wiper blade adaptor 10. The supporting surface 32 closes off the coupling element 12 upward. Upon installation with the wiper blade adaptor 10, the latter rests on the supporting surface 32.
The wiper blade adaptor 10 has skirt-shaped side guide means 48 laterally. A guide means 36 extends on each of the side guide means 48, for the most part in the longitudinal direction 22, as shown in
In a fitted state, each extension 34 forms a form-fitting connection to the latching means 18. As furthermore shown in
In order to couple the wiper blade adaptor 10 to the coupling element 12, the wiper blade adaptor 10 is received by the longitudinal guide unit 24 of the coupling element 12 in a pushing-on movement, as shown in
During the pushing-on movement, the latching means 18 is elastically deflected out of a starting position perpendicular to the supporting surface 32 of the coupling element 12 by the base plate 44 of the wiper blade adaptor 10. After the base plate 44 has been pushed over the latching means 18, the latching means 18 automatically moves back into the starting position thereof. In the process, it forms a form-fitting connection to the extension 34 of the wiper blade adaptor 10. Furthermore, the latching means 18 bears flush against the latching stop 46.
In a fitted state, the basic body 28 bears against the locking cam 42. This avoids the wiper blade adaptor 10 being pushed too far onto the coupling element 12. The wiper blade adaptor 10 is now fixedly connected to the coupling element 12.
In order to release the wiper blade adaptor 10 from the coupling element 12 again, the latching element 18 has to be pressed downward, i.e. perpendicularly to the supporting surface 32. For as long as the latching element 18 is deflected, the wiper blade adaptor 10 can be pushed out of the fitted state and removed in an analogous manner to installation.
