Description

Windscreen wipers, in particular for a windscreen wiper system of a motor vehicle, with a mounting adapter and at least one rear blade, which are connected together State of the art The invention relates to a windshield wiper that can be used, in particular, for a windshield wiper system of a motor vehicle. Specifically, the invention relates to the field of windshield wiper systems for passenger cars and trucks. A flat-design windshield wiper is known from document DE 102004058511 A1. The known windshield wiper has blades without clamps. Disclosure of the invention The windshield wiper according to the invention, with the features of the main claim, has the advantage of allowing for improved configuration and operation. This enables better attachment between the wiper components. Furthermore, the replacement of a wiper blade can be facilitated and / or the attachment of a wiper blade can be improved. Additionally, a modular structure can be implemented, allowing for the manufacture of various construction variants by varying individual components. The measures set forth in the secondary claims also give rise to advanced developments and advantageous improvements of the features specified in the main claim. The concept of a windshield wiper should be understood in a broad sense. In particular, a windshield wiper can be configured as a flat-bar wiper. Preferably, the wiper can be attached to a wiper arm or a similar drive device of a wiper system, particularly a windshield wiper system. The wiper can clean a car window, particularly a windshield, during operation. The wiper can also be suitable for other uses. For example, it can also clean a rear window. It is advantageous for the structural component to have a U-shaped guide on its first longitudinal side and for at least one back sheet to be inserted into the U-shaped guide of the structural component on the first longitudinal side. This ensures reliable fastening. Furthermore, an advantageous assembly is possible in which the back sheet, optionally along with other components mounted on it, is inserted into the U-shaped guide of the structural component. It is advantageous for the structural component to have a U-shaped guide on its second longitudinal side and for at least one rear leaf to be inserted into the U-shaped guide of the structural component, also located on the second longitudinal side. This ensures reliable fastening. Furthermore, it allows for an advantageous assembly in which the rear leaf, along with other components mounted on it, is inserted into the U-shaped guide of the structural component. It is advantageous for the fixing adapter to be connected to the back leaf so that at least one back leaf can be engaged, in particular inserted, into the fixing adapter in at least one direction that is at least approximately perpendicular to its longitudinal extension. This makes it particularly easy to attach the fixing adapter to the back leaf. It is advantageous for the fixing adapter to be securely connected to at least one back panel. This eliminates gaps between components and ensures a stable connection. It is advantageous that a back panel is provided and that this panel has at least one fixing opening into which a fixing protrusion provided on the fixing adapter can be inserted. This allows for a configuration with an optimized number of components. It is advantageous to provide a first and a second back leaf, and for the fixing adapter to have a first cavity facing the first longitudinal side of the structural component, into which the first back leaf is inserted, and a second cavity facing the second longitudinal side of the structural component, into which the second back leaf is inserted. This facilitates easy assembly. It is advantageous for the first cavity to be configured as a receiving groove that extends along the longitudinal extension through the fixing adapter, and / or for the second cavity to be configured as a receiving groove that extends along the longitudinal extension through the fixing adapter. This allows for robust and reliable fixing. It is advantageous to provide a first and a second wiper element, with the mounting adapter positioned between them. This allows for a configuration with wiper elements. In one possible configuration, the wiper elements may have spoilers. It is advantageous that the first cleaning element has a first cavity facing the first longitudinal side of the structural component, into which the first rear sheet is inserted, and that the first cleaning element has a second cavity facing the second longitudinal side of the structural component, into which the second rear sheet is inserted. This allows for easy assembly. It is advantageous that the second cleaning element has a first cavity facing the first longitudinal side of the structural component, into which the first rear leaf is inserted, and that the second cleaning element has a second cavity facing the second longitudinal side of the structural component, into which the second rear leaf is inserted. This allows for easy assembly. It is advantageous for the first cavity to be configured as a receiving groove extending along the longitudinal extension through the first wiper element, and / or for the second cavity to be configured as a receiving groove extending along the longitudinal extension through the first wiper element. This allows for robust and reliable attachment of the first wiper element to the back plates. It is advantageous that the first cavity is configured as a receiving groove extending along the longitudinal extension through the second cleaning element, and / or that the second cavity is configured as a receiving groove extending along the longitudinal extension through the second cleaning element. This allows for robust and reliable attachment of the first cleaning element to the rear leaves. It is also advantageous that an end cap is provided that attaches to a cleaning element along its longitudinal extension and that the structural component secures the end cap on its first and second longitudinal sides. This allows for reliable attachment of the end cap to the structural component. It is advantageous that another end cap has been provided, which is attached to a cleaning element along its longitudinal length, and that the structural component secures the other end cap on its first and second longitudinal sides. This allows for a reliable attachment of the other end cap to the structural component. It is advantageous that a recess is provided on at least one of the longitudinal sides of the structural component, that the end cap has a locking element, in particular a latch, and that the locking element, in particular the latch, of the end cap fits, and in particular is locked, into the recess of the structural component when mounted. This allows for a reliable fastening while facilitating easy assembly and disassembly. This enables, for example, a user, particularly a vehicle driver, to replace a wiper blade without having to go to a workshop. It is advantageous to provide an additional recess on at least one of the longitudinal sides of the structural component, to have a locking element, particularly a latching element, on the additional end cap when assembled, and to ensure that the locking element, particularly the latching element, of the additional end cap engages, and in particular is locked, into the additional recess of the structural component. This allows for reliable fastening while facilitating assembly and disassembly. For example, a user, particularly a vehicle driver, can thus replace a wiper blade without having to go to a workshop. It is advantageous for at least one wiper element to be configured with a spoiler. With this configuration, at least one wiper element can have a spoiler. This allows, in particular, the use of identical pre-produced parts—wiper elements with and, optionally, without spoilers—when the wiper is assembled according to a modular system. It is advantageous that an end cap has been provided and that a spoiler has been configured on the end cap. This configuration is especially advantageous with a spoiler provided on the corresponding windshield wiper element to extend a spoiler. It is advantageous that an additional end cap has been provided and that a spoiler has been configured on this additional end cap. This configuration is particularly advantageous with a spoiler provided on the corresponding wiper element to extend the spoiler. It is advantageous that an end cap has been provided and that the back leaf, at least one of them, is inserted in sections through the end cap. This allows for a more secure attachment of the end cap to the back leaf. It is advantageous that another end cap has been provided and that at least one rear leaf passes through this other end cap in sections. This allows for advantageous attachment of the other end cap to the rear leaf. It is advantageous that the cleaning lip and the structural component are configured as a single piece. This ensures a reliable attachment of the cleaning lip to the structural component, preventing, for example, the cleaning lip from shifting relative to the structural component along its longitudinal length. It is advantageous for the wiper lip and the structural component to be configured as a single extruded component. This allows for a reliable bond with optimized manufacturing costs. It is advantageous to have a wiper lip fitting configured along the longitudinal extension of the structural component, into which the wiper lip is inserted. With this configuration, if necessary, only the wiper lip needs to be replaced, allowing the structural component to be reused. It is advantageous for the structural component to have at least one wing, specifically one, positioned on its first longitudinal side. This configuration allows for the efficient fabrication of the wing. If necessary, assembly can be based on a modular system, enabling configurations with or without a wing depending on the application. This allows for configurations suitable for various applications at a reduced manufacturing cost. For example, a configuration with a spoiler can be implemented for vehicle markets where high wiper performance is desired even at high speeds. It is advantageous for the structural component to have at least one wing, and in particular exactly one, positioned on its second longitudinal side. This configuration allows for the wing to be manufactured efficiently. If necessary, assembly can be based on a modular system, so that, depending on the application, a configuration with or without a wing is possible. This allows for configurations suitable for different applications at a reduced manufacturing cost. For example, a configuration with a spoiler can be implemented for vehicle markets where high wiper performance is desired, even at high speeds. Especially in the case of a structural component configuration with at least one spoiler, the spoilers on the wiper elements and end caps can be omitted. However, a wiper configuration without spoilers is also possible. The structural component can also be used to reliably secure the end cap and / or the other end cap. It is advantageous to have a recess on at least one of the longitudinal sides of the structural component, to have a locking element on the end cap, particularly a locking mechanism, and for the locking element, particularly the locking mechanism, of the end cap to engage, or rather, lock into place, in the recess of the structural component when assembled. This allows for easy assembly and avoids the need for complex fastening solutions. It is advantageous to provide an additional recess on at least one of the longitudinal sides of the structural component, to have a locking element, particularly a latching element, on the additional end cap, and to ensure that the locking element, particularly the latching element, of the additional end cap fits, or rather locks, into the additional recess of the structural component when assembled. This facilitates easy assembly and avoids the need for complex fastening solutions. Furthermore, depending on the configuration and application case, the following features and advantages can be achieved. A wiper blade can be designed to allow for easy replacement of the wiper lip. In this case, a configuration can be implemented that allows only part of the wiper blade to be replaced. In one configuration, only the wiper lip is replaceable. In another configuration, the wiper lip can be replaced along with another wiper component, particularly a structural component. This allows for a simple exchange that can be conveniently performed by a user, especially a vehicle driver. The windshield wiper can be designed so that it can be easily disassembled, at least partially. It can also be completely disassembled. The wiper can be configured so that disassembly can be performed by a user, eliminating the need to visit a workshop. In an advantageous configuration, the cleaning elements attached to at least one brush and / or the attachment adapter are firmly joined together, so that these components cannot be separated from each other. The windshield wiper may be configured so that it can be mounted entirely onto a wiper arm or similar component and then removed from it. This can facilitate the replacement of the wiper blade. In the windshield wiper, at least one wiper blade may be accessible on its longitudinal sides, at least essentially, along its entire longitudinal length, to allow its attachment to the structural component. The structural component may include other wiper components along its longitudinal sides. In particular, the structural component may include one end cap and another end cap along its longitudinal sides. In this case, the structural component may extend longitudinally along the length of the component. Because the structural component is attached to the back leaf or leaves on the outer longitudinal sides, a particularly rigid configuration can be achieved. The wiper blade can be attached particularly rigidly to the windshield wiper, i.e., to the mounting adapter. This allows for high cleaning performance. The windshield wiper may include a mounting adapter, a first wiper element, a second wiper element, a first end cap, a second end cap, a backing blade, and a structural component. The first wiper element and the second wiper element may each have a spoiler. The first end cap and the second end cap may each have a spoiler. The fixing adapter can be inserted into the back sheet between the first and second cleaning elements. In this case, the fixing adapter can be positioned at least approximately in the center of the back sheet or between the first and second cleaning elements. For this purpose, the first and second cleaning elements can be the same length along their longitudinal extension. In particular, the first and second cleaning elements can have the same configuration. Consequently, the fixing adapter can also be placed at least approximately in the center of several back sheets. The cleaning elements and / or the fixing adapter can be placed on the back sheet at least approximately perpendicular to the longitudinal extension. Additionally, the end caps can be placed on the ends of the back sheet. The mounting adapter and / or cleaning elements may be inseparably attached to at least one brush. Specifically, the components may be joined by welding, hot pressing, or similar methods. This connection may also be made with a geometric locking mechanism, resulting in a gap-free and / or highly robust joint. The mounting adapter may have at least one mounting protrusion, although it is preferable that it have approximately four, ideally exactly four. These mounting protrusions can be inserted into a corresponding number of mounting cavities, particularly mounting holes. The components can be further joined together, especially by welding, hot pressing, or similar means. This creates an inseparable connection. Accordingly, cleaning elements with more than one fixing sheet can be joined by welding, hot pressing or similar means. The windshield wiper can be configured as a flat-beam wiper. In this case, one or more rear blades can be provided. Additionally, spoilers can be incorporated into the wiper components. These spoilers can be located on the wiper elements and / or the structural component. However, a configuration without spoilers is also possible. The end caps may have rails or rail pieces along their longitudinal sides, which connect at the ends to the corresponding rail pieces on at least one back sheet as the components are arranged longitudinally. The rails or rail pieces are then assembled to form a track on which the structural component can be placed or slid from either side. This configuration allows the structural component to be easily disassembled and reassembled if necessary. This enables, where applicable, simple replacement of the structural component, particularly in conjunction with a wiper blade. In the assembled state, the structural component may encompass the back leaf or leaves together with the end pieces at least essentially along its entire length in the longitudinal direction on the longitudinal sides. The back panel, at least one of them, with the components mounted on it, in particular the fixing adapter, cleaning elements and end pieces, if applicable, can be inserted into the structural component. This allows for easy assembly. The windshield wiper can be easily removed and reassembled. A locking mechanism can be used for this purpose. In a preferred configuration, a locking element, in particular an interlocking element, is provided on at least one end cap, which fits into a recess in the structural component. In this case, it is possible to easily release the lock so that, for example, a user, particularly a vehicle driver, can easily remove the structural component. The locking element can be actuated, for example, by pressing it. In a modified configuration, the locking element can also be actuated by pulling it. Other methods of actuating the locking element are also possible. For example, the locking element can also be configured as a latch. In a configuration where only one of the two end caps has a locking element, the end cap with the locking element may be located at either end of the wiper blade. On a wiper blade that moves across the windshield with the rotating motion of a wiper arm, the end cap with the locking element may be on the inside or outside, or on the outer or inner circle. If the locking mechanism is configured as an interlock, the structural component can automatically lock into place during assembly when the components are in their predetermined positions relative to each other. The interlocking mechanism allows the locking element to engage in the recess. This engagement can be accompanied by an audible signal for the user. This allows the user to intuitively and correctly reassemble the wiper blade after replacing it. During the joining or assembly procedure, the locking element is preferably held under pre-tension until it clicks into place in the recess. The brush can then be replaced by pressing the locking element in again. In a modified configuration, the locking element can also be pulled to release the lock. Specifically, the locking element can be configured so that a user pulls a button on the locking element to release it. Even with this configuration, the locking element is preferably pre-tensioned during assembly or installation until it engages in the recess. In particular, the lock can be released if a user moves the locking element out of the structural component cavity by pushing or pulling it and, for example, bending a tab, so that the locking element is under pre-tension, which is relevant during assembly. A cavity that serves for locking can be arranged in the structural component in such a way that it points inwards. The structural component and the wiper blade can perform two different functions and be configured accordingly. The wiper blade can be made of a soft material suitable for cleaning glass, especially a windshield. The structural component can be made of a material that provides the required mechanical stability and rigidity. Specifically, the structural component can be shaped as a rigid structural component through the choice of material. This allows for optimization of the windshield wiper's mechanical stability. The structural component and the wiper blade are preferably formed as a single extruded component (coextrusion component). In a modified configuration, the wiper blade may also be connected to the structural component in another way. In one possible configuration, the wiper blade may be connected to the structural component by means of a geometric closure. In particular, it is possible to detach the wiper blade from the structural component and thus replace only the wiper blade. The structural component can consist of one or more wings. Depending on the configuration, the wing(s) and the structural component can also be extruded together. However, modified configurations are also possible. For example, the wing(s) can be fixed to the structural component or attached to it in another way. This allows for standardized manufacturing of the structural component, especially within a modular system. It also enables the assembly of a structural component without wings, for example, if a windshield wiper without wings is desired.

Ways of realizing the invention Figure 1 shows a windshield wiper 1 in a schematic and spatial representation corresponding to a first embodiment. Figure 1 shows the windshield wiper 1 mounted. Figure 2 shows the windshield wiper shown in Figure 1 in a general representation. Figure 2 shows the wiper blade in its completely disassembled state. After assembly, wiper blade 1 is not necessarily disassemblable into the components shown in Figure 2. Wiper blade 1 is specifically designed for a motor vehicle's wiper system. A possible configuration is explained in more detail below, also with reference to figs. 3 and 4. Fig. 3 shows a schematic representation to explain the assembly of the windshield wiper 1 shown in Fig. 1. The windshield wiper 1 comprises a structural component 2 and a wiper lip 3 extending along a longitudinal extension 4. The wiper lip 3 is arranged and attached to the structural component 2, as explained in more detail in Figures 11 and 12. Furthermore, the windshield wiper has a first wiping element 5 and a second wiping element 6, as well as a fixing adapter 7. The structural component 2 has a first longitudinal side 8 and a second longitudinal side 9, which run at least approximately parallel to the longitudinal extension 4. In this configuration of the windshield wiper 1, two rear blades 15, 16 and a fixing adapter 7 are provided. The wiping elements 5, 6 and the fixing adapter 7 are connected to the rear blades 15, 16. In the assembled state (Fig. 1), the structural component 2 holds the two rear blades 15, 16 by their first longitudinal side 8 and their second longitudinal side 9. Figure 4 shows the fixing adapter 7 and the corresponding rear blades 15, 16 for this wiper blade configuration 1 in a schematic representation; the representation is oriented transversely to the longitudinal extension 4 and an assembly is explained. The assembly then leads to the state shown in Figure 3. The fixing adapter 7 is connected to the rear leaves 15, 16, as shown in fig. 3 in the assembled state. In addition, end caps 17, 18 have been provided. The end cap 17 is joined to the cleaning element 5 along the longitudinal extension 4. The other end cap 18 is joined to the cleaning element 6 along the longitudinal extension 4. The structural component 2 holds the end cap 17 at one end and the other end cap 18 at the other end, on its first longitudinal side 8 and its second longitudinal side 9, respectively. The rear leaves 15, 16 are guided or inserted in sections through the end cap 17. In addition, the rear leaves 15, 16 are guided or inserted in sections through the other end cap 18. In this case, an interlocking may occur inside the end caps 17, 18, in which case, for example, the interlocking projections fit into the cavities 15A, 16A of the rear leaves 15, 16. In one possible configuration, on the cleaning elements 5, 6, wings 19, 20 can be configured. Consequently, in one possible configuration, on the end covers 17, 18, wings 21, 22 can be configured. Structural component 2 has a U-shaped guide 25 on its first longitudinal side 8. The rear sheet 15 is inserted into the U-shaped guide of structural component 2 provided on the first longitudinal side 8. In addition, structural component 2 has a U-shaped guide 26 on its second longitudinal side 9. The rear sheet 16 is inserted into the U-shaped guide 26 of structural component 2 provided on the second longitudinal side 9. In the configuration shown in Figures 3 and 4, in which a first rear leaf 15 and a second rear leaf 16 are provided, the fixing adapter 7 has a first cavity 27 oriented towards the first longitudinal side 8 of the structural component 2, into which the first rear leaf 15 is inserted. In addition, the fixing adapter 7 has a second cavity 28 oriented towards the second longitudinal side 9 of the structural component 2, into which the second rear leaf 16 is inserted. In this configuration example, the first cavity 27 is configured as a receiving slot 27 extending along the longitudinal extension 4 through the fixing adapter 7. Accordingly, the second cavity 28 is configured as a receiving slot 28 extending along the longitudinal extension 4 through the fixing adapter 7. The receiving slots 27, 28 are oriented in opposite directions. Consequently, a fixation can be made between the cleaning elements 5, 6 and the back leaves 15, 16. The first cleaning element 5 has a first cavity 27A oriented towards the first longitudinal side 8 of the structural component 2, into which the first back leaf 15 is inserted. In addition, the first cleaning element 5 has a second cavity 28A oriented towards the second longitudinal side 9 of the structural component 2, into which the second back leaf 16 is inserted. Accordingly, the second cleaning element 6 has a first cavity 27B oriented towards the first longitudinal side 8 of the structural component 2, into which the first rear leaf 15 is inserted. In addition, the second cleaning element 6 has a second cavity 28B oriented towards the second longitudinal side 9 of the structural component 2, into which the second rear leaf 16 is inserted. In this example configuration, the first cavity 27A is configured as a receiving slot 27A extending along the longitudinal extension 4 through the first wiper element 5. Furthermore, the second cavity 28A is also configured as a receiving slot 28A extending along the longitudinal extension 4 through the first wiper element 5. Correspondingly, the first cavity 27B is configured as a receiving slot 27B extending along the longitudinal extension 4 through the second wiper element 6. Similarly, the second cavity 28B is configured as a receiving slot 28B extending along the longitudinal extension 4 through the second wiper element 6. The fixing adapter 7 can be connected without play to the back leaves 15, 16. A modified configuration is explained below using figures 5 to 7. Figure 5 shows a representation of the components of a windshield wiper 1 corresponding to Figure 3, showing a modified configuration with exactly one rear blade 15. In addition, Figure 6 shows a detail corresponding to Figure 4, explaining the assembly of the modified configuration of Figure 5. Furthermore, Figure 7 shows a detail of the modified configuration shown in Figures 5 and 6. In this embodiment, a rear leaf 15 is provided. The fixing adapter 7 is connected to the rear leaf 15, as shown in Fig. 6, by inserting the fixing adapter 7 in the 30' direction onto the rear leaf 15. This is equivalent to saying that the rear leaf is placed into the fixing adapter 7 in the 30' direction, i.e., opposite to the 30' direction. In this way, the fixing adapter 7 and the rear leaf 15 can be joined. Specifically in this embodiment, the rear leaf 15 has fixing holes 31, 32, 33, and 34. The fixing adapter 7 with a geometric locking mechanism can be inserted into fixing holes 31, 32, 33, and 34 of the rear leaf 15. For this purpose, the fixing adapter 7 has fixing protrusions 41, 42, 43, and 44. Fig. 8 shows a general representation to explain the assembly of the back sheets 15, 16 shown in Fig. 3 with the fixing adapter 7 and other components on the structural component 2, illustrating the sliding of the structural component 2 along the longitudinal extension 4. Rails 46, 47 are assigned to the longitudinal sides 8, 9, which in the assembled state are located on the rear leaves 15, 16 and on the end caps 17, 18. The U-shaped guides 25, 26 slide on these rails 46, 47. In this way, a stable fixation is achieved. Figure 9 shows a detail of structural component 2 to illustrate a locking mechanism, in which a cavity 50 is shown on the longitudinal side 8. Furthermore, Figure 10 shows the end cap 17 to illustrate the locking mechanism, where a locking element 51 is shown which, in the assembled state, fits into the cavity shown in Figure 9. To clarify the assembly conditions, a direction IX is marked in Figures 9 and 10. The locking element 51 is formed in this embodiment as a snap-in element 51. The snap-in element 51 of the end cap 15 is locked into the cavity 50 of the structural component 2 when assembled. In a modified configuration, the cavity 50 can also be provided on the second longitudinal side 9. In addition, a modification is possible in which, in addition to or alternatively to a locking element 51 on the end cap 15, a corresponding locking element 51 is provided on the end cap 16, which fits into a cavity 50 provided correspondingly on the first longitudinal side 8 or on the second longitudinal side 9. Figure 11 shows a structural component 2 with a wiper lip 3 corresponding to a one-piece configuration. In particular, the wiper lip 3 and the structural component 2 can be in the form of a jointly extruded component 55. Figure 12 shows a structural component 2 with a wiper lip 3 corresponding to a two-piece configuration. In this embodiment, the structural component 2 has a wiper lip setting 56 extending along the longitudinal extension 4. The wiper lip setting 56 has L-shaped guides 57, 58. The wiper lip 3 is inserted along the longitudinal extension 4 into the wiper lip setting 56, i.e., between the L-shaped guides 57, 58. Fig. 13 shows a structural component 2 according to a modified configuration, in which wings 60, 61 have been provided on the longitudinal sides 8, 9 of the structural component 2. In this case, one wing 60 is arranged on the first longitudinal side 8. The other wing 61 is arranged on the second longitudinal side 9. As shown by means of the schematic flow line 62, the wings 60 and 61 are arranged in such a way that both are swept by an airflow caused, for example, by the running wind. The invention is not limited to the embodiments described.
