Description

[0001] The invention relates to a driver arrangement for a displaceable window pane, in particular of a motor vehicle, with a driver which has a receiving recess for receiving an edge section of the window pane and an elastically displaceable locking lug which is designed to engage in a locking recess of the window pane, wherein the locking lug blocks the receiving recess in its initial position and has at least one insertion bevel associated with the receiving recess, so that the locking lug is displaced into a position releasing the receiving recess by inserting the window pane into the receiving recess.

[0002] Furthermore, the invention relates to a window pane arrangement, in particular for a motor vehicle, with a displaceable window pane and with a driver arrangement of the type mentioned above assigned to the window pane.

[0003] Driver assemblies and window pane assemblies of the type mentioned above are generally already known from the prior art. Adjustable or sliding window panes in motor vehicles are usually guided in a frame, for example, a vehicle door, and are adjusted by a driver that is driven along a guide track via a drive device, whereby the window pane connected to the driver can be raised or lowered. To push the window pane upwards, for example, it is sufficient for the driver to be pressed against a lower side edge of the window pane. In order for the window pane to be moved in the opposite direction by the driver, the driver must be firmly connected to the window pane. For this purpose, it is known to provide the driver with a locking lug, which allows simple and tool-free installation of the driver on the window pane.A corresponding driver is already known, for example, from published patent application DE 10 2012 223 825 A1. Published patent application DE 10 2012 208 562 A1 also discloses a generic driver arrangement. In both cases, the driver has a receiving recess into which the window pane can be inserted with an edge portion. When the window pane is inserted, it strikes the locking lug, which is provided with an insertion bevel. This is assigned to the receiving recess in such a way that when the window pane is inserted into the receiving recess, the locking lug is displaced from its initial position into a position that releases the receiving recess. The window pane has a locking receptacle in the edge portion, into which the locking lug engages due to its inherent elasticity when the window pane is pushed further into the driver, thereby positively locking the window pane to the driver.

[0004] To prevent the driver arrangement from being easily released with the aid of an auxiliary tool, for example by inserting a narrow sheet of metal through an opening gap between the window pane and frame and sliding it between the locking lug and the window pane, so that the locking lug is thereby displaced from the locking recess in the window pane, the aforementioned published patent applications propose safeguards intended to prevent unauthorized release of the locking mechanism. In the latter publication, for example, it is provided that an angle piece is attached to the window pane. This angle piece has a section protruding perpendicularly from a window pane, which the auxiliary tool would hit and thus no longer reach between the locking lug and the window pane. However, this angle piece requires a relatively large installation space in order to be able to cover the locking lug.In addition, the angle piece must be sufficiently strong to absorb high forces. Current state-of-the-art solutions are generally complex in design and thus result in correspondingly high manufacturing costs.

[0005] The invention is therefore based on the object of creating a driver arrangement and a window pane arrangement which reliably prevents improper manipulation of the connection between the driver and the window pane in a simple and cost-effective manner.

[0006] The object underlying the invention is achieved by a driver arrangement having the features of claim 1. This has the advantage that a very simple and cost-effective design measure increases security against unwanted release of the locking mechanism, whereby the proposed solution can also withstand high machining forces. The driver arrangement ensures in a simple manner that a manipulation tool used cannot exert a force on the locking lug that could lead to a release of the locking mechanism. The driver arrangement according to the invention does not prevent a manipulation tool or auxiliary tool from applying a force to the locking lug itself. However, the solution according to the invention ensures that a force exerted by the auxiliary tool on the locking lug cannot lead to a release of the locking mechanism.Thus, machining forces from the auxiliary tool continue to be absorbed by the locking lug, but cannot lead to a release of the locking mechanism. According to the invention, this is achieved by arranging at least one wedge element on the window pane associated with the locking lug, which wedge element has a safety bevel that leads to the insertion bevel of the locking lug, wherein the insertion bevel and the safety bevel enclose an angle α greater than or equal to 90°.The wedge element applied to the window pane is thus designed and arranged such that an auxiliary tool guided into the gap between the window pane and the frame is guided toward the insertion bevel by the safety bevel of the wedge element. Due to the advantageously selected angle, the tool guided toward the insertion bevel meets the insertion bevel at such an angle that it is guided away from the gap between the insertion bevel and the window pane and thus cannot be pushed between the insertion bevel and the window pane to release the locking mechanism. The wedge element thus serves to deflect a manipulation tool or auxiliary tool in such a way that it can no longer release the locking mechanism.Because this safety element is designed as a wedge element and has a safety bevel that leads toward the insertion bevel, i.e., away from the window pane, the wedge element does not have to be able to absorb high forces. This makes attaching the wedge element to the window pane itself simple and cost-effective.

[0007] According to a preferred embodiment of the invention, the wedge element is glued to the window pane. As already mentioned, the wedge element does not have to absorb high forces from the auxiliary tool / manipulation tool, so that simply gluing the wedge element to the window pane is sufficient for positioning and secure locking. In particular, the wedge element is secured to the window pane by a double-sided adhesive strip. Alternatively, the back of the wedge element can also be coated with a liquid or solid adhesive during installation and then pressed onto the window pane.

[0008] Furthermore, it is preferably provided that the wedge element has a width that at least substantially corresponds to the width of the insertion bevel. This ensures that, regardless of where an unauthorized person applies the manipulation tool, the manipulation tool is always deflected in such a way that the locking mechanism cannot be released. Depending on the width of the locking lug, it may also be sufficient for the wedge element to be narrower, in particular half as narrow as the locking lug.

[0009] According to a preferred embodiment of the invention, the wedge element is made of plastic. This allows the wedge element to be manufactured cost-effectively and is lightweight, so that, for example, an adjustment mechanism for operating the driver or for moving the window pane is not burdened by additional weight.

[0010] Furthermore, it is preferably provided that the wedge element is held positively to the window pane. The wedge element is thus held to the window pane by a positive fit, in addition to or as an alternative to adhesive bonding, so that it can also absorb higher processing forces from a manipulation tool. This further increases the security of the driver assembly against unintentional / undesired release of the locking mechanism.

[0011] In particular, it is provided that the window pane has at least one recess in which a projection of the wedge element is inserted. For example, the wedge element can have one or more projections, for example in the form of pins, on its rear side facing the window pane, which engage in corresponding receptacles in the window pane, so that the wedge element is held immovably and positively on the window pane.

[0012] The window pane assembly according to the invention with the features of claim 7 is characterized by the inventive design of the driver assembly. This results in the advantages already mentioned. Further features and advantages emerge from the above description and from the claims.

[0013] In the following, the invention will be explained in more detail using an exemplary embodiment. Figure shows a window pane arrangement of a motor vehicle in a simplified sectional view.

[0014] The single figure shows a simplified sectional view of a window pane arrangement 1 with a window pane 2 and with a driver arrangement 3.

[0015] The driver assembly 3 serves to move the window pane 2 up and down in a frame (not shown here), as indicated by a double arrow 4. For this purpose, the driver assembly 3 is driven, for example, by an electric actuator device and displaced along a guide rail or the like to move the window pane 2. In order to be able to transport the window pane 2 in both directions, i.e., up and down, through the driver assembly 3, the latter has a driver 5 that is positively connected to the window pane 2.

[0016] The driver 5 has a receiving recess 6 in which an edge section 7 of the window pane 2 is received. The receiving recess 6 is designed such that the window pane 2 is held in the receiving recess 6 essentially in a form-fitting manner and preferably essentially free of play. In particular, the width of the receiving recess 6 shown in the side view corresponds to the width of the window pane 2 at its edge region 7. At its lower side edge 8, the window pane 2 preferably rests on the driver 5 so that the driver 5 can move the window pane 2 upwards by an upward movement. In order to be able to move the window pane 2 in the opposite direction, the driver 5 has a locking device 9.

[0017] The locking device 9 has an elastically displaceable locking lug 10 which extends through the receiving recess 6 and thus blocks the receiving recess 6. On its upper side, the locking lug 10 has an insertion bevel 11 facing the window pane 2, which has a plurality of guide sections 12, 13 and 14. The guide sections 12 and 11 are designed such that they enclose different angles with the window pane 2, wherein the guide section 12 and the guide section 14 enclose an identical or almost identical angle with the window pane 2 or with a surface of the window pane 2, and the guide section 13 encloses a comparatively smaller angle, wherein the guide section 13 lies between the guide sections 12 and 14.The locking lug 10 is designed such that, in particular, the guide section 14 extends through the receiving recess or, in its initial position, lies in the receiving recess 6, as shown in the figure. The first guide section 12 and the second guide section 13 are essentially assigned to the outer side 15 of the window pane 2, which faces outwards as seen from the motor vehicle. The window pane 2 itself has a locking recess 16 which, when inserted into the receiving recess 6, lies in the region of the locking lug 10, so that the locking lug 10 extends through the locking recess 16 in the mounted state and thereby forms a positive connection with the window pane 2 in the direction of displacement of the window pane 2 according to the double arrow 4. An underside of the locking lug 10 is assigned to a lower edge of the locking recess 16 such that the locking lug 10 rests on the lower edge of the locking recess 16.If the driver 5 is pulled downwards, a tensile force is securely transferred to the window pane 2 by the locking lug 10.

[0018] When assembling the window pane arrangement 1, the window pane 2 is simply pushed from above into the receiving recess 6 with its side edge 8 first. The side edge 8 then meets the insertion bevel 11 of the locking lug 10. The insertion bevel 11 causes the locking lug 10 to be displaced outwards from the area of the receiving recess 6. The locking lug 10 is connected, for example, to a side wall 17 of the driver 5 that delimits the receiving recess 6 on the outside, wherein the side wall 17 is in particular itself elastically designed or is elastically held on the driver 5 so that it can be displaced accordingly together with the locking lug 10.As soon as the locking lug 10 has been moved from its initial position into the position releasing the receiving recess 6, the window pane 2 can be pushed completely with its edge section 7 into the receiving recess 6 until it stops, so that the locking recess 16 lies in an area of the locking lug 10. Due to the inherent elasticity of the mounting of the locking lug 10, it automatically springs back into its initial position, as shown in the figure, in which it lies in the locking recess 16 in order to positively lock the driver 5 to the window pane 2.

[0019] The driver assembly 3 further comprises a safeguard 18 to prevent unauthorized release of the locking mechanism. For this purpose, the driver assembly 3 comprises a wedge element 19, which is attached to the outer side 15 of the window pane 2 and has a safety bevel 20 that runs from the outer side 15 of the window pane 2 in the direction of the insertion bevel 11. The wedge element 19 is arranged in the region of the guide sections 12 and 13 in the assembled state of the window pane 2, so that the safety bevel 20 lies substantially above the guide section 12 of the insertion bevel 11. The safety bevel 20 is followed by a further bevel 21, which runs almost parallel to the guide section 13, so that it leads to the outer side 15 of the window pane 2 in the direction of the locking recess 16.

[0020] The wedge element 19 is designed and arranged on the window pane 2 in such a way that the safety bevel 20 in its extension leads to the guide section 12, wherein the safety bevel 20 and the guide section 12 of the insertion bevel 11 enclose an angle of α > 90° between them.

[0021] In this case, the wedge element 19 is attached to the outer side 15 of the window pane 2 by an adhesive strip 22. Optionally, the wedge element 19 may also have one or more projections 23, for example in the form of pins, as shown in the figure, on its side facing the window pane 2, which projections lie in corresponding recesses 24 of the window pane 2, so that the wedge element 19 is also held in a form-fitting manner on the window pane 2.

[0022] If a manipulation attempt is now made, for example by inserting a manipulation tool 25 in the form of a sheet metal strip or the like into a gap between the window pane 2 and the door frame in order to move the locking lug 10 out of the locking recess 16, the tip of the manipulation tool 25 strikes the safety bevel 20 of the wedge element 19 and is deflected by the bevel in the direction of the guide section 12 of the insertion bevel 11. Due to the advantageously selected angle of α > 90°, the manipulation tool 25 then strikes the guide section 12 at an angle at which no forces can be transferred to the locking lug 10 that would lead to the locking lug 10 being moved out of the locking recess 16.

[0023] According to the invention, it is also provided, as shown in the figure, that the locking lug 10 is designed to be elastically deformable in the region of the guide section 12, for example, by designing the section of the locking lug 10 forming the guide section 12 as an elastically deformable web. If the manipulation tool 25 now strikes the guide section 12, the locking lug 10 is also elastically deformed in this region due to the angle of impact of the manipulation tool 25 on the guide section 12, so that the guide section 12 yields and the manipulation tool 25 cannot exert any force on the locking lug 10 to release it.

[0024] Overall, this provides a simple and cost-effective solution for increasing the security of the window assembly 1 against unauthorized release of the locking mechanism. Conveniently, the width of the wedge element 19 corresponds at least substantially to the width of the locking lug 10, so that even narrow manipulation tools 25 are prevented from releasing the locking mechanism.
