Description
Background
A wiper blade arrangement with at least one retaining unit has already been proposed, wherein the retaining unit has a receiving region for a wiper blade adapter and at least one spring rail groove for at least one spring rail.
Disclosure of Invention
A wiper blade arrangement is proposed with at least one holding unit having a receiving region for a wiper blade adapter and at least one spring rail groove for at least one spring rail and at least one fastening recess which is provided for fastening the wiper blade adapter, the extension of the fastening recess along the spring rail groove being smaller than the extension of the receiving region along the spring rail groove. With the inventive design, a wiper blade arrangement can be provided which enables a particularly reliable fixing of the spring rail and the wiper blade adapter by means of the retaining unit.
The term "holding unit" is understood to mean, in particular, a unit which is provided for connecting at least one wind deflector, at least one spring strip, at least one wiper strip and/or at least one wiper blade adapter to one another, in particular to one another. The holding unit is provided in particular for accommodating the spring rails at least partially, in particular at least largely, particularly preferably completely, in the circumferential direction. "at least predominantly" in this connection means in particular more than 50%, preferably more than 80%, particularly preferably more than 95%. In particular for accommodating the wiper blade adapter, the holding unit at least partially, preferably at least largely, particularly preferably completely, forms an accommodating region for the wiper blade adapter. By "receiving region for a wiper blade adapter" is meant in particular a region and/or a section of the holding unit which is provided, in particular, to at least partially receive the wiper blade adapter. Preferably, the receiving area is at least free of wind-blocking elements. "provided" means in particular specially designed and/or provided. "an item is provided for a certain function" means in particular that the item fulfils and/or carries out said certain function in at least one state of use and/or operation.
"wiper blade adapter" is in particular in connection with an adapter which has a contact area which is in contact with a wiper blade component, in particular a spring strip, and which is connected to the wiper blade component in the mounted state in a non-releasable manner and which is provided for providing a coupling area of the wiper blade component for coupling and/or contacting with a wiper arm adapter. "wiper arm adapter" refers in particular to an adapter which has a contact area for contacting a wiper arm component and is connected non-detachably to the wiper arm component and is provided for providing a coupling area of the wiper arm component for coupling and/or contacting the wiper arm adapter.
For accommodating the spring rails, the retaining unit forms at least partially, preferably at least largely, the spring rail groove. "spring rail groove" is understood to mean, in particular, a groove which is provided to receive a spring rail. The "extension" of an object means in particular the maximum distance between two points of the perpendicular projection of the object on a plane. "longitudinal" refers in particular to the main direction of extension of the spring rail groove. The "main extension direction" of an object is in particular a direction parallel to the longest side of a virtual minimum geometric cube that exactly surrounds the object. Advantageously, the spring rail groove has a closed contour in at least one plane.
"spring strip" means in particular a macroscopic component which has at least an extension which can be elastically changed by at least 10%, in particular at least 20%, preferably at least 30%, particularly advantageously at least 50%, in the normal operating state, and which in particular generates a counter force which is dependent on a change in the extension, preferably proportional to the change, and which counteracts such a change. Preferably, the spring rails are made at least partially of spring steel. Preferably, the spring rails have substantially the shape of a bent rod in the unloaded state, particularly advantageously a flat bent rod. Furthermore, the spring rails are advantageously constructed in one piece. Alternatively, the spring rails can also be of a multi-component design. It is particularly advantageous if the curvature of the spring rails along the spring rails in the unloaded state is greater than the curvature of a vehicle surface of the motor vehicle, in particular the curvature of a vehicle window, along which the spring rails are guided in at least one operating state. "elastic article" is intended to mean, in particular, an article which can be deformed repeatedly without mechanically damaging or destroying the article, and which automatically returns to its original shape, in particular after deformation.
The fastening recess is provided in particular for accommodating at least one fastening means, in particular of a wiper blade adapter. The fixing groove, in particular the wall of the object with the fixing groove defining the fixing groove, is advantageously provided for preventing the object arranged at least partially in the fixing groove from moving. The fastening recess is provided in particular for at least partially accommodating the wiper blade adapter. In particular, the holding unit at least partially encloses the wiper blade adapter, especially viewed along the spring rail groove. By "one article at least partially sandwiches another article" is meant, in particular, that there is at least one straight line which first extends through the first article, then through the other article, and then through the first article. The fixing groove is in particular a vertical groove. "vertical groove" means in particular a groove which passes at least largely, preferably completely, through at least one object in at least one vertical direction. "vertical direction" in particular means a direction which extends at least substantially perpendicularly to the surface to be brushed by the wiper strip. Preferably the vertical direction extends perpendicular to the brushing direction. "brushing direction" in particular means a direction which runs parallel to the surface to be brushed and in particular runs at least substantially perpendicular to the longitudinal and vertical directions. Furthermore, the vertical direction advantageously runs perpendicular to the longitudinal direction of the wiper strip. The fixing groove preferably has a rectangular cross section. The term "at least substantially perpendicular" here especially defines an orientation of a direction relative to a reference direction, wherein the direction and the reference direction, especially viewed in a plane, enclose an angle of 90 °, which has especially a maximum deviation of especially less than 20 °, advantageously less than 10 °, especially advantageously less than 5 °.
"wind-guard element" is in particular a component which is provided to counteract air jets acting on the wiper blade arrangement or to counteract driving wind and/or to press the wiper strip against the surface to be brushed. The wind deflector is preferably at least partially made of rubber and/or at least partially made of an elastic plastic. Preferably the wind-shield member has at least one concave flushing surface. The wind-blocking part is offset in particular from the end cap, the wiper strip and/or the wiper blade adapter. Advantageously, the wind deflector extends in the longitudinal direction over at least a part, preferably at least a majority, of the extension of the wiper blade arrangement in the operating state. The wind-blocking element is preferably constructed in one piece. "wiper strip" in particular relates to a strip which is provided for brushing the glass of a vehicle. The wiper strip is preferably made of a rubber material.
In particular, the wind deflector and/or at least the wiper strip are arranged at least partially, preferably at least largely, on the holding unit, in particular are at least partially integrally formed with the holding unit. Furthermore, it is preferred that the windshield, the wiper strip and/or the retaining unit are produced in one piece by a coextrusion process. By "at least partially integrally" is meant, in particular, that at least one component of at least one object and/or at least one first object is constructed integrally with at least one component of at least one further object and/or is constructed integrally with at least one further object. "integrally" is intended to mean, in particular, at least a material-to-material connection, for example, by means of a welding process, an adhesive process, an injection molding process and/or another process which appears to be expedient to the person skilled in the art. "integrally" is advantageously also intended to mean "integrally". "integrally" means in particular that it is formed from one component part. This component part is preferably produced from individual blanks, blocks and/or castings, particularly preferably by injection molding, in particular by single-component and/or multi-component injection molding.
The extent of the fixing recess along the spring rail groove is advantageously at most 90%, preferably at most 70%, particularly preferably at most 50% and/or in particular at least 10%, preferably at least 20%, particularly preferably at least 30% of the extent of the receiving region along the spring rail groove. This makes it possible to precisely position the wiper blade adapter on the holding unit, in particular during installation.
Furthermore, it is proposed that the retaining unit has at least one further fixing groove, which is at least partially, preferably completely, configured in accordance with the fixing groove and is arranged offset with respect to the fixing groove along the spring rail groove. This advantageously makes it possible to distribute the force uniformly over the holding unit. "two articles are at least partially congruent" means in particular that the two articles have at least openings of the same size, in particular their main extension faces have in particular the same contour and/or the same shape. The two articles are in particular identical if their main extension faces coincide. The "main extension plane" of an object is in particular the largest side of the smallest virtual geometric cube that exactly completely surrounds the object. The fixing groove and the further fixing groove are arranged in particular offset to one another, so that their projections, viewed in the brushing direction, at least partially overlap. The fastening groove and the further fastening groove are arranged, in particular, on mutually opposite different sides of the holding unit, in particular, as viewed along the spring rail groove. The fixing groove and the further fixing groove are preferably arranged rotationally symmetrically about a central axis of rotation of the holding unit. "central axis of rotation" is understood to mean, in particular, an imaginary axis of rotation which extends at least to a large extent through the center of gravity of the object. In the present case, the central axis of rotation extends at least substantially perpendicularly to the longitudinal direction, in particular perpendicularly to the surface to be brushed. The holding unit has in particular an additional fixing groove.
It is further proposed that the wiper blade arrangement has a spring rail which is provided in particular for accommodating into a spring rail groove and has at least one latching recess which, in the mounted state of the spring rail, at least partially overlaps the fastening recess. A particularly stable connection between the spring rails, the retaining unit and the wiper blade adapter can thereby be produced. Advantageously, at least the locking groove and at least the fixing groove are at least partially superposed one above the other. "at least partially superimposed" means in particular that the main extension faces of the two items are at least partially covered. In particular, the locking recess, in particular its main extension, overlaps at least 10%, preferably at least 20%, particularly preferably at least 30% and/or at most 70%, preferably at most 60%, particularly preferably at most 50%, with the fixing recess, in particular its main extension.
It is further proposed that the spring rail has at least one further locking groove, which is configured in accordance with the locking groove and is arranged along the spring rail offset relative to the locking groove. This makes it possible to distribute the force uniformly over the spring rails. The locking groove and the further locking groove are arranged, in particular, on different sides of the spring rail, in particular, opposite to each other, as viewed along the spring rail groove. The locking groove and the further locking groove are preferably arranged rotationally symmetrically about a central rotational axis of the spring bar. In particular, it is conceivable for the retaining unit to have additional latching recesses.
It is further proposed that the wiper blade device has a wiper blade adapter which has at least one fastening means which is arranged at least partially in the fastening recess in the installed state. This makes it possible to secure the wiper blade adapter to the holding unit. In particular, the extension of the fastening means along the spring rail groove is smaller than the fastening groove, in particular by at least 60%, preferably by at least 80%, particularly preferably by at least 100%. In particular, at least 10%, preferably at least 20%, particularly preferably at least 30% and/or at most 70%, preferably at most 60%, particularly preferably at most 50% of the main extension surface of the fixing means overlaps the fixing groove.
It is further proposed that the wiper blade adapter has at least one further fastening means which is of identical construction to the fastening means and is arranged offset with respect to the fastening means along the spring rail groove. This makes it possible to distribute the force uniformly to the wiper blade adapter. The fastening means and the further fastening means are arranged, in particular, on mutually opposite different sides of the wiper blade adapter, in particular, as viewed along the spring rail groove. The fastening means and the further fastening means are preferably arranged rotationally symmetrically about a central axis of rotation of the wiper blade adapter. In particular, it is conceivable for the wiper blade adapter to have an additional retaining mechanism.
Furthermore, it is proposed that the fastening means be provided for at least partially enclosing the spring rail. The wiper blade adapter can thereby be fixed to the spring rail in the vertical direction. The fixing means in particular have a guide groove which is provided for guiding the spring rail.
It is further proposed that the wiper blade adapter has at least one locking mechanism which is provided for at least partial insertion into the locking recess and the fastening recess in the mounted state. The spring rails can thereby be fixed along the spring rail grooves relative to the retaining unit and the wiper blade adapter.
In an advantageous embodiment of the invention, it is provided that the locking mechanism is designed as a bolt-type part. This allows simple assembly. The locking mechanism is preferably constructed as a separate component. The wiper blade adapter has in particular at least one receiving recess which is provided for at least partially receiving the locking mechanism. The locking mechanism can be configured in particular as a screw.
In a preferred embodiment of the invention, it is provided that the locking mechanism is designed as a latching hook. This advantageously makes it possible to install without tools. In particular, the locking mechanism is at least substantially integrally connected with the wiper blade adapter. "latching hook" is understood to mean, in particular, a spring mechanism for producing a latching connection, which is provided for elastic deflection during installation.
In a preferred embodiment, it is provided that the wiper blade adapter is designed at least in two-component fashion, preferably in multiple-component fashion. This simplifies the production, since complex components such as wiper blade adapters cannot be extruded, in particular because of their shape, but can be easily assembled from two or more extruded components. The wiper blade adapter advantageously has a first component and a second component, which can be connected to one another in a form-fitting and/or force-fitting manner. The first and/or second component preferably have form-fitting parts which are configured in particular in correspondence with one another. The first component preferably has at least one fastening means and the second component in particular has at least one locking means. In an alternative design, only the first component or only the second component may have a fixing mechanism and a locking mechanism.
A method for mounting a wiper blade arrangement is proposed, wherein a wiper blade adapter is arranged at least partially in a receiving region, a spring rail is inserted into a spring rail groove in such a way that a locking recess at least partially overlaps a securing recess, and the spring rail is secured by means of a locking mechanism, the securing recess and the locking recess. This makes it possible to secure the spring rails and the wiper blade adapter particularly reliably by means of the retaining unit.
The wiper blade device of the present invention is not limited to the above-described applications and embodiments. In particular, the wiper blade device according to the invention can have a number of components, components and units differing from the number mentioned therein for the purpose of achieving the operating mode described here.
