[0004] The present invention proposes that the glass scraper device includes at least one coupling unit configured to close the fluid channel according to the position of the adapter relative to the fluid connector.

[0005] "Set up" should be understood in particular as designed and / or equipped.

Preferably, the coupling unit is arranged at least partially, especially at least substantially, between the fluid connector and the adapter. Preferably, the fluid connector is configured to move relative to the adapter, at least during coupling or decoupling with the scraper. In particular, the coupling unit is arranged at least partially on the fluid connector and at least partially on the adapter, especially in at least one operating state. Preferably, the coupling unit is configured to close the fluid passage by means of a force and / or form-locking connection during relative movement of the fluid connector and the adapter, wherein, in particular, the position of the adapter relative to the fluid connector or the position of the fluid connector relative to the adapter changes. Particularly preferably, the coupling unit is configured to close the fluid passage if at least one spacing between the adapter and the fluid connector changes, particularly along at least one coupling path (Koppelstrecke), i.e., expands or shrinks. It is conceivable that the coupling path extends at least partially along the axis and / or at least partially arcuate around the axis.

[0006] The term "glass wiper assembly" should preferably be understood as at least a portion, preferably a group of sub-components, of a glass wiper. It is conceivable that the glass wiper assembly comprises the entire glass wiper. Preferably, the glass wiper assembly is configured for use on a vehicle. Preferably, the glass wiper assembly is configured for cleaning surfaces, preferably cleaning the glass on a vehicle. Preferably, a fluid connection is provided for a wiper blade adapter that guides fluid, particularly a wiper water mixture, from the fluid container and / or fluid piping elements of the wiper arm to the wiper blade via a fluid channel. In particular, the fluid channel has at least one inlet opening and at least one outlet opening on the wiper blade side, respectively arranged at opposite ends of the fluid channel. Preferably, the inlet opening and the outlet opening on the wiper blade side are defined by the fluid connection. Preferably, the fluid channel is constructed as at least one channel-shaped groove and / or at least one channel defined by a hose-like and / or at least one tubular element, wherein the channel-shaped groove and / or the channel defined by the hose-like and / or tubular element is configured to guide fluid, preferably a scraping water mixture. In particular, the fluid connector at least substantially completely defines the fluid channel, especially except for the inlet and outlet openings. "Substantially completely defining" a component or volume, especially the fluid channel, by another component or volume, especially the fluid connector, should be understood in particular to mean that at least 90%, preferably at least 95%, particularly preferably at least 98%, and very particularly preferably at least 99% of the entire outer surface surrounding the component or volume is covered or surrounded by the other component or volume, wherein the other component or volume particularly rests against the outer surface. Particularly preferably, the coupling unit is at least partially arranged on and / or inside the fluid channel in at least one operating state. Preferably, the coupling unit is configured to fluidly separate the scraper blade, particularly the scraper blade adapter, from the scraper arm, particularly the scraper arm adapter, by closing the fluid channel. Preferably, the glass scraper device has at least one assembled state, wherein the coupling unit is configured to release the fluid channel in the assembled state, particularly in the position of the adapter relative to the fluid connector, to guide fluid. Preferably, the glass scraper device has at least one disassembled state, wherein the coupling unit is configured to close the fluid channel at least during coupling from the disassembled state to the assembled state and / or at least during decoupling from the assembled state to the disassembled state. Preferably, the adapter is configured to cooperate with the scraper arm adapter and / or the scraper blade adapter during coupling or decoupling for movement, particularly positional changes, relative to the fluid connector. Particularly preferably, the scraper arm adapter is integrally constructed with the scraper bar of the scraper arm. "Integral" should be understood in particular as a material locking connection, such as by welding and / or bonding processes, and particularly advantageously formed, for example by casting and / or by injection molding methods of one or more components.Particularly preferably, the fluid-technical connection between the scraper arm adapter and the scraper blade adapter is configured to be particularly temporarily separable via the glass scraper device during coupling and / or decoupling processes. Preferably, the fluid channel is configured as at least one channel-shaped groove and / or at least one channel defined by a tubular element, wherein the channel-shaped groove and / or the channel defined by the tubular element is configured to guide fluid.

[0007] According to the design of the glass wiper device of the present invention, the fluid passage can be advantageously and automatically closed during the coupling or decoupling of the wiper blade and the wiper arm. Undesirable and / or unintentional leakage of the wiper water mixture from the wiper arm can be advantageously prevented during the coupling or decoupling of the wiper blade. This results in a high degree of safety for the user when changing the wiper blade.

[0008] Furthermore, it is proposed that the fluid connector, adapter, and coupling unit are constructed as part of the aforementioned scraper arm. Advantageously, this allows the function of the glass scraper device, particularly for sealing the fluid passage, to be independent of the scraper blade, especially independent of the replacement of the scraper blade. An advantageously simple and cost-effective design for the scraper blade can be achieved, especially because the main components of the glass scraper device can be arranged on the scraper arm independently of the scraper blade. The fluid connector, adapter, and coupling unit being constructed as part of the scraper arm should be understood in particular to mean that the fluid connector, adapter, and coupling unit are arranged on at least one component of the scraper arm, especially the scraper arm adapter, independently of the operating state of the scraper arm, especially when the scraper arm is arranged at intervals from the scraper blade. Preferably, the fluid connector, adapter, and / or coupling unit are arranged directly and / or indirectly on the scraper arm, especially the scraper arm adapter. In particular, the fluid connector, adapter, and / or coupling unit are connected to the scraper, especially the scraper adapter, during coupling. In particular, the fluid connector, adapter, and / or coupling unit are separated from the scraper, especially the scraper adapter, during decoupling. Alternatively, the fluid connector, adapter, and / or coupling unit may be constructed as part of the scraper, especially the scraper adapter.

[0009] Furthermore, it is proposed that the coupling unit includes at least one valve element disposed on the fluid connector and configured to close the fluid passage according to the position of the adapter relative to the fluid connector. Advantageously, a safe and sealed closure of the fluid passage can be achieved. Preferably, the valve element is at least partially disposed on and / or at least partially disposed within the fluid passage. Preferably, the valve element is fixed to and / or integrally constructed with the fluid connector. In particular, the valve element can be mechanically, electrically, electronically, hydraulically, and / or pneumatically actuated. Particularly preferably, the valve element is configured to be actuated to open or close the fluid passage according to the position of the adapter relative to the fluid connector. For example, the valve element is configured as a spring-loaded, especially cylindrical, spherical, and / or rectangular plug, which closes the fluid passage by moving against the spring force into the fluid passage according to the position of the adapter relative to the fluid connector. It is also conceivable that the valve element is configured as a check valve, wherein the coupling unit is configured to match the return force of the valve element according to the position of the adapter relative to the fluid connector. In particular, the valve element is configured to completely seal or seal the fluid passage in a waterproof manner.

[0010] Furthermore, it is proposed that the coupling unit includes at least one guiding element configured to guide the fluid connector on the adapter during movement relative to the adapter. Advantageous directional relative movement of the fluid connector and the adapter can be achieved. The adapter and / or fluid connector can be advantageously supported on the scraper arm, particularly the scraper arm adapter. Advantageous, accurate, and reliable manipulation of the coupling unit to close the fluid passage is possible. Preferably, the fluid connector is movably supported on the adapter and the scraper arm adapter via the coupling unit, particularly the guiding element. Preferably, the guiding element is configured such that the adapter is guided relative to the fluid connector along the coupling path. Particularly preferably, the guiding element is arranged on the adapter or the fluid connector. In particular, the guiding element is integrally constructed with the adapter or the fluid connector. Preferably, the coupling unit includes at least one mating guiding element corresponding to the configuration of the guiding element. Preferably, the mating guiding element is arranged on the adapter or the fluid connector. In particular, the mating guide element is integrally constructed with the adapter or fluid connector. Preferably, the guide element is constructed on an adapter or fluid connector that is constructed independently of the other guide element. Preferably, the guide element and the other guide element are configured to engage in a mechanical manner on the fluid connector during movement relative to the fluid connector in order to guide the adapter. For example, the guide element is constructed as a tenon, pin or bolt, track, protrusion, or similar structure. For example, the mating guide element, especially corresponding to the guide element, is constructed as a groove, as a recess defined especially by the fluid connector or adapter, as a roller, or similar structure. In particular, the guide element and the mating guide element are jointly constructed as an elongated guide portion, or as a rolling guide portion, as a track guide portion, or similar structure.

[0011] Furthermore, it is proposed that the adapter has at least one tilting axis (Kippachse) about which it can move relative to the fluid connector during coupling or decoupling. The coupling unit is configured to completely close the fluid channel, particularly when the tilting angle of the adapter relative to the fluid connector, especially in the closing direction, about the tilting axis is greater than 5°, preferably greater than 10°, and particularly preferably greater than 15°. It is advantageous to simultaneously close the fluid channel and separate the scraper blade from the scraper arm, especially because the scraper blade is configured to separate from the scraper arm by movement about the tilting axis. An advantageously high tolerance range for the movement of the scraper blade relative to the scraper arm about the tilting axis can be achieved during scraping, particularly regardless of the closure of the fluid channel. Preferably, the closing direction is oriented at least substantially perpendicular to the tilting axis. "Substantially perpendicular" should be understood in particular as the orientation of a straight line, plane, or vector, especially a directional vector of a closed direction, relative to another straight line, plane, or vector, especially the tilting axis, wherein the straight line, plane, or vector, when viewed especially in a projection plane, forms an angle of 90° with the other straight line, plane, or vector, and the angle has a maximum deviation of less than 8°, advantageously less than 5°, and particularly advantageously less than 2°. In particular, the scraper blade is configured to separate from the scraper arm, especially the scraper arm adapter, by movement relative to the scraper arm along a direction oriented opposite to the closed direction. In particular, the coupling path is arranged, especially at least partially, in an arc around the tilting axis. Preferably, the tilting axis is oriented at least substantially perpendicular to the main extension axis of the scraper arm, especially the scraper arm adapter, and / or the scraper blade, especially the scraper blade adapter. The “main extension axis” of an object, particularly a scraper arm, scraper arm adapter, scraper blade, and / or scraper blade adapter, should be understood in particular as an axis parallel to the longest side of the geometrically smallest parallelepiped that just completely encloses the object. Particularly preferably, the scraper blade, particularly the scraper blade adapter, is configured to move about a tilting axis during coupling or decoupling. Preferably, the coupling unit has at least one locking position corresponding to the position of the fluid connector and the adapter relative to each other, in which the valve element is just fully closed. Additionally, it is conceivable that the coupling unit is configured to completely close the fluid passage at a tilting angle relative to the fluid connector, oriented in a direction opposite to the closing direction, about the tilting axis at a angle greater than 2°, preferably greater than 4°, and particularly preferably greater than 6°. In particular, the valve element and / or coupling unit are configured such that the valve element closes to one of at least two locking positions along and against the closing direction when moving relative to the adapter and fluid connection.

[0012] Furthermore, it is proposed that the coupling unit includes at least one coupling element, which is at least partially arranged on the valve element and at least partially on the adapter, and is configured to cooperate with the valve element such that, when the adapter moves relative to the fluid connection to at least one, particularly the aforementioned locking position, the valve element completely closes the fluid passage. Advantageous direct closure of the fluid passage can be achieved. Advantageous simple and cost-effective coupling between the adapter and the fluid connection can be achieved. Advantageous low susceptibility to failure, particularly due to dust, dirt, and / or wear, can be achieved in the coupling unit for closing the fluid passage. Preferably, the coupling element is configured as a mechanical coupling element that cooperates with the adapter, the fluid connection, and / or the valve element by form-locking and / or force-locking when the adapter moves relative to the fluid connection to the locking position, wherein, in particular, the valve element completely closes the fluid passage. In particular, the coupling element extends at least partially along the coupling path between the adapter and the fluid connection. Preferably, the locking position is the relative position of the adapter and the fluid connection relative to each other, wherein, in particular, the adapter and the fluid connection are arranged tilted relative to each other about a tilting axis. Specifically, the coupling unit is configured to prevent relative movement of the adapter and the fluid connection beyond the locking position, and / or, when relative movement of the adapter and the fluid connection exceeds the locking position, to close the fluid passage, particularly by means of a valve element. Preferably, the coupling element is integrally constructed with the valve element or the adapter. Preferably, the coupling element has at least one coupling surface that abuts against the adapter, fluid connection, and / or valve element for cooperation with the coupling element. Preferably, the coupling unit includes at least one stop surface configured to cooperate with the coupling element, particularly the coupling surface. Preferably, the coupling surface is arranged on the adapter or fluid connection, particularly independently of the coupling element. However, it is also possible to consider that the coupling element is constructed as an integral part of the valve element or the fluid connection and as an integral part of the adapter.

[0013] Furthermore, it is proposed that the coupling unit includes at least one reset element arranged on the fluid connector or the adapter and configured to, particularly in at least one disassembled state, apply a force to the adapter and / or the fluid connector in a direction pointing towards the locking position. Advantageously and reliably closing of the fluid passage can be achieved in the disassembled state of the glass wiper assembly, especially because the reset element can hold the adapter and the fluid connector in the locked position. Undesirable leakage of the wiper water mixture can be advantageously prevented when replacing the wiper blade. In particular, in at least one operating state, the reset element rests against the adapter at one end and against the fluid connector at the other end. Preferably, the reset element is arranged and / or constructed such that the adapter and / or the fluid connector are subjected to a force in a direction at least substantially parallel to the coupling path and / or at least substantially perpendicular to the tilt axis orientation. "Substantially parallel" should be understood here in particular as the orientation of a straight line, a plane, or a vector, especially the direction vector of a direction, relative to another straight line, another plane, or another vector, especially the orientation of a coupling path and / or a tilting axis, wherein the straight line, the plane, or the vector has a deviation of less than 8°, advantageously less than 5°, and particularly advantageously less than 2° relative to the other straight line, the plane, or the vector. In particular, according to one design of the valve element and / or coupling element, it is conceivable that the reset element is configured to pull the fluid connection and the adapter toward each other in the direction toward the locking position or to push the fluid connection and the adapter away from each other in the direction toward the locking position. For example, the reset element is constructed as a spring, especially a pressure spring or a tension spring, as a hydraulic or pneumatic piston, as a magnet, or a similar structure. Especially in a design where the reset element is a magnet, the adapter and / or fluid connection is preferably at least partially made of a ferromagnetic or paramagnetic material.

[0014] Furthermore, it is proposed that the glass wiper device includes at least one wiper arm adapter base, wherein a fluid connector for fluidically connecting the wiper arm and the wiper blade can be fixed to the wiper blade, particularly the aforementioned wiper blade adapter, and wherein the adapter, in at least one assembled state, is movably configured relative to the wiper blade adapter and the fluid connector together with the wiper arm base. Advantageous automatic closure of the fluid passage can be achieved when removing and / or replacing the wiper blade from the wiper arm. Advantageous, safe, and residue-free removal of the wiper blade from the wiper arm is possible, especially because undesirable leakage of fluid from the fluid conduit elements of the wiper blade can be advantageously prevented. In particular, the wiper arm adapter base is configured to move relative to the wiper blade adapter and the fluid connector about a tilting axis for separation from the wiper blade. Preferably, the fluid connector is configured, in particular, to separate the scraper blade from the scraper arm, after or simultaneously with the movement of the scraper arm adapter base and the adapter about the tilting axis.

[0015] Furthermore, a scraper arm having at least one glass scraper device according to the invention is proposed. In particular, a fluid connector, an adapter, and a coupling unit are configured as part of the scraper arm.

[0016] According to the design of the scraper arm according to the invention, the fluid channel can be advantageously and automatically closed during the coupling or decoupling of the scraper blade and the scraper arm. Undesirable and / or unintentional leakage of the scraping water mixture from the scraper arm can be advantageously prevented during the coupling or decoupling of the scraper blade. This results in a high degree of safety for the user when replacing the scraper blade.

[0017] Furthermore, a glass scraper having at least one glass scraper device according to the invention is proposed.

[0018] According to the design of the glass wiper according to the present invention, the fluid channel can be advantageously and automatically closed during the coupling or decoupling of the wiper blade and the wiper arm of the glass wiper. Undesirable and / or unintentional leakage of the wiping water mixture from the wiper arm can be advantageously prevented during the coupling or decoupling of the wiper blade. This results in a high degree of safety for the user when changing the wiper blade.

In particular, the scraper 16 is configured to separate from the scraper arm 14, and especially from the scraper arm adapter 32, by movement relative to the scraper arm 14 in a direction oriented opposite to the closing direction 80. The coupling path 74 is arranged at least substantially around the tilt axis 76. In particular, the coupling path 74 is arranged, at least partially, in an arc shape around the tilt axis 76. The tilt axis 76 is oriented at least substantially perpendicular to the main extension axis 52 of the scraper arm adapter 32 and perpendicular to the main extension axis 54 of the scraper adapter 28. Particularly preferably, the scraper 16, and especially the scraper adapter 28, is configured to move about the tilting axis 76 during decoupling.

[0035] The adapter 40 is movable relative to the fixing element 60 of the scraper adapter 28 and is fixed to the scraper arm adapter 32. However, it is also conceivable that the adapter 40 is fixed to the fixing element 60 of the scraper adapter 28 in the assembled state. The fluid connector 36, together with the scraper adapter 28, is movable relative to the scraper arm adapter 32 and is connected to the fluid connection element 64 of the scraper adapter 28. The adapter 40 is configured to move relative to the fluid connector 36 about the tilting axis 76, particularly along the coupling path 74, especially during decoupling, for the purpose of removing the scraper 16. The adapter 40 at least partially surrounds the fluid connector 36. The adapter 40 has a stop surface 82 arranged on the side of the adapter 40 facing the fluid connector 36. The stop surface 82 is provided for loading the fluid connector 36 or coupling unit 42, particularly the coupling element 84 of the coupling unit 42, with a force oriented in the direction of movement of the adapter 40 relative to the fluid connector 36 (see...). Figure 6 The stop surface 82 is oriented at least substantially parallel to the main extension axis 52 of the scraper arm adapter 32 and at least substantially parallel to the tilting axis 76. In particular, the stop surface 82 is arranged on the inner side of the adapter 40 facing the fluid connector 36. Preferably, the stop surface 82 is configured as part of the coupling unit 42 and is provided to, particularly by cooperating with the coupling element 84, close the fluid passage 38 defined by the fluid connector 36 according to the position of the adapter 40 relative to the fluid connector 36. However, other designs for the adapter 40, especially the stop surface 82, are also contemplated.

[0036] exist Figure 6 and 7 A schematic cross-sectional view of the fluid connector 36 is shown, particularly with a cutting plane oriented at least substantially perpendicular to the tilting axis 76. The coupling unit 42 is at least substantially disposed on the fluid connector 36. The coupling unit 42 includes a valve element 86 disposed on the fluid connector 36 and configured to close the fluid passage 38 according to the position of the adapter 40 relative to the fluid connector 36. Figure 6 The diagram schematically illustrates the position of the adapter 40 relative to the fluid connection 36 when the fluid passage 38 is released by the valve element 86. Especially... Figure 6 and 7Only the stop surface 82 of the adapter 40 facing the fluid connector 36 is shown. A valve element 86 is at least partially arranged within the fluid passage 38. The fluid connector 36, and in particular the fluid passage 38, is configured to guide fluid from the fluid line element 44 to the scraper adapter 28, and in particular to the fluid connection element 64. The valve element 86 is secured to the fluid connector 36 by a spring element 90. The spring element 90 is arranged on the inner wall of the fluid connector 36 defining the fluid passage 38. The valve element 86 is configured to be mechanically operable. Particularly preferably, the valve element 86 is configured to be operable to open or close the fluid passage 38 according to the position of the adapter 40 relative to the fluid connector 36. The valve element 86 is configured as a spherical plug that moves into the fluid passage 38 according to the position of the adapter 40 relative to the fluid connector 36 to close the fluid passage 38 against the spring force of the spring element 90. However, other designs for valve element 86 can also be considered, such as a Schrader valve, a Dunlop valve, or a similar configuration. In particular, valve element 86 is configured to completely or waterproofly close the fluid passage 38. Coupling unit 42 includes coupling element 84, which is at least partially arranged on valve element 86 and configured to engage with valve element 86, particularly by engaging with stop surface 82, when adapter 40 moves relative to fluid connection 36 to at least one locked position, thereby completely closing the fluid passage 38. Figure 7The diagram shows the adapter 40 and fluid connector 36 in the locked position, wherein the adapter 40 moves or tilts relative to the fluid connector 36 about a tilting axis 76 at a tilting angle 78 of 11°. The coupling element 84 is configured as a mechanical coupling element that, when the adapter 40 moves relative to the fluid connector 36 to the locked position, engages with the stop surface 82 of the adapter 40 and the valve element 86 by form-locking and / or force-locking, wherein the valve element 86, in particular, completely closes the fluid passage 38. Preferably, the movement of the coupling element 84 along the coupling path 74 is limited by the valve element 86 and the fluid passage 38. In particular, the coupling unit 42, and especially the coupling element 84, is configured to prevent relative movement between the adapter 40 and the fluid connector 36 beyond the locked position. It is conceivable that the coupling element 84 is integrally constructed with the valve element 86 and / or the adapter 40, especially the stop surface 82. Preferably, the coupling element 84 has at least one coupling surface 92, which abuts against the adapter 40 so that the coupling element 84 engages with the stop surface 82 of the adapter 40. However, it is also conceivable that the coupling element 84 is integrally constructed with the valve element 86 or the fluid connector 36 and with the adapter 40, wherein the fluid passage 38 is closed or opened, particularly directly, by the movement of the adapter 40 relative to the fluid connector 36. However, other designs for the coupling unit 42, and especially the coupling element 84, are also conceivable. Preferably, the mechanical connection between the scraper adapter 28 and the scraper arm adapter 32 and the fluid-technical connection between the scraper adapter 28 and the scraper arm adapter 32 are constructed independently and can be connected or separated at different values ​​of the tilt angle 78. Particularly preferably, the glass scraper device 34 is configured to at least temporarily close the fluid passage 38 when the scraper blade adapter 28 moves relative to the scraper arm adapter 32, so as to separate the mechanical connection between the scraper blade adapter 28 and the scraper arm adapter 32.

[0037] Additionally, it is conceivable that the coupling unit 42 includes a reset element 94 disposed on the fluid connector 36 or adapter 40 and configured to, particularly in at least one disassembled state, apply a force pointing in the direction of the locked position to the adapter 40 and / or fluid connector 36. The reset element 94 in Figure 6 and 7 The diagram illustrates an exemplary arrangement. Specifically, in at least one operating state, the reset element 94 rests with one end against the adapter 40 and the other end against the fluid connector 36. Figure 6In the illustrated design, the reset element 94 is arranged or fixed to the fluid connection 36. Preferably, the reset element 94 is arranged and / or constructed such that the adapter 40 and / or the fluid connection 36 are subjected to a force in a direction at least substantially parallel to the coupling path 74 and / or at least substantially perpendicular to the tilting axis 76. In particular, according to the design of the valve element 86 and / or the coupling element 84, it is conceivable that the reset element 94 is configured to push the fluid connection 36 and the adapter 40 apart from each other or retain them in the locked position in a direction toward the locked position (see [link to design]). Figure 7 For example, especially as Figure 6 and Figure 7 As shown, the reset element 94 is constructed as a spring, particularly a compression spring. However, other designs for the reset element 94 are also possible, such as designing it as a magnet. Especially when the reset element 94 is designed as a magnet, the adapter 40 and / or the fluid connection 36 are preferably at least partially made of ferromagnetic and / or paramagnetic materials.
