Description

[0001] Fitting arrangement for a lift-and-slide element with a detachable connection between the faceplate and the gear box

[0002] The present invention relates to a fitting arrangement for raising and lowering a lifting-sliding element, in particular a lifting-sliding door, wherein the fitting arrangement comprises a gear box containing an actuating gear, and a faceplate for covering a fitting groove formed in a lifting-sliding element, to which faceplate the gear box is fastened and along which a drive rod coupled to the actuating gear in a drive-effective manner is guided in a translationally displaceable manner.

[0003] The drive rod serves in a manner known per se for the drive-effective coupling of the actuating gear with a lifting element for raising and lowering a lifting-sliding element and / or with a locking element of an additional locking device, such as a mushroom-head pin or a hook bolt, which is rotatably mounted in a lock case of the additional locking device and can be pivoted between its locking position and its unlocking position by means of an actuating gear received in the lock case by means of the drive rod.

[0004] In order to be able to move the drive rod translationally, the actuating gear located in the gear box has, for example, an input shaft rotatably mounted in the gear box, which can be rotated by means of an actuating lever about an axis between a locking position corresponding to the lowered position of the lifting-sliding element and an unlocking position corresponding to the raised position of the lifting-sliding element, so that by rotating the input shaft, the drive rod and, via this, a lifting element coupled to it can be actuated to raise and lower a lifting-sliding element. Since the lock case of an additional locking device also has an actuating gear, in the context of the present invention the lock case of such an additional locking device is also referred to as a gear box for the sake of simplicity, especially since the lock case of an additional locking device is also usually attached to the faceplate.

[0005] The fitting arrangement consisting of the faceplate and the gear box attached to it usually represents a uniform functional unit, since the gear box is usually firmly or permanently connected to the faceplate, for example by means of riveted connections.

[0006] If, for example, the gear box needs to be replaced, this is usually not possible because the gear box often cannot be removed from the faceplate without causing damage.

[0007] The invention is therefore based on the object of further developing a fitting arrangement of the type described above in such a way that a non-destructive replacement of the gearbox is possible.

[0008] This object is achieved with a fitting arrangement having the features of claim 1 and in particular in that the gear box is releasably secured to the faceplate perpendicular to the longitudinal extent of the faceplate exclusively by means of at least one clip or snap-in connection.

[0009] If it is stated here that the gear box is releasably secured to the faceplate perpendicular to the longitudinal extension of the faceplate exclusively by means of at least one clip connection, this means that no further connecting means other than the clip connection in question are provided that prevent relative movement between the gear box and faceplate in a direction perpendicular to the longitudinal extension. However, additional securing or fastening means may be provided that prevent relative movement between the gear box and faceplate in the longitudinal direction of the faceplate.

[0010] For example, to replace the gear box of the fitting assembly with a new one, it is only necessary to loosen at least one clip connection, after which the gear box can be pulled off the faceplate in a direction perpendicular to its longitudinal extension. Replacing the gear box, and in particular removing it from the faceplate, can thus be performed by untrained personnel or even by the end user without any special tools, since the locking of the clip or snap connection can be released using a conventional screwdriver or similar tool.

[0011] In the following, specific embodiments of the invention will be discussed, whereby further details may also arise from the dependent claims, the description of the figures and the figures themselves.

[0012] For example, according to one embodiment, the faceplate may comprise two flanges extending parallel and spaced apart from one another, as well as a web connecting the two flanges. The faceplate is thus essentially a U-profile, with at least one locking opening formed in each flange of this U-profile, preferably at least two locking openings spaced apart from one another in the direction of the longitudinal extension of the faceplate. Each locking opening accommodates one of several locking hooks, in particular in a substantially form-fitting manner, which are formed on the gear box.

[0013] By accommodating the locking hooks in the locking openings in question, the gear box is held captively on the faceplate, in particular perpendicular to the longitudinal extent of the faceplate. The locking openings can in particular be through-openings formed in the flanges of the faceplate, the contour of which essentially corresponds to the contour of the locking hooks in order to be able to accommodate the latter in a substantially form-fitting manner. Since the locking openings are preferably through-openings formed in the flanges of the faceplate, the locking hooks are accessible from the outside through the locking openings and can thus be deflected, for example using a screwdriver, in order to be able to release the locking or form-fitting connection between the respective locking hooks and the associated locking opening.

[0014] To facilitate the installation of a gear box on the faceplate, a further embodiment provides for an alignment recess to be formed perpendicular to the longitudinal extent of the faceplate, adjacent to at least one locking opening, preferably adjacent to each locking opening, at the free end of the respective flange. This alignment recess serves to temporarily accommodate and guide at least one locking hook during installation of the gear box on the faceplate. Thus, during installation of the gear box on the faceplate, the locking hooks can first be inserted into the alignment recesses in question, so that the gear box is already in the correct position in the longitudinal direction of the faceplate.Starting from this intermediate assembly position, it is then only necessary to press the gear box perpendicular to the longitudinal extension of the faceplate until the locking hooks engage the locking openings formed in the faceplate flanges. The correct alignment of the gear box in the longitudinal direction of the faceplate does not need to be laboriously determined by longitudinally shifting the gear box relative to the faceplate, as the alignment recesses in the longitudinal direction of the faceplate are provided exactly where the corresponding locking openings are located.

[0015] Since the previously described clip connection primarily serves to secure the gear box to the faceplate in a direction perpendicular to its longitudinal extent, a further embodiment can provide for at least one slot extending perpendicular to the longitudinal extent of the faceplate in at least one flange of the faceplate, preferably in both flanges, which slot extends from the free end of the flange in the direction of the web of the faceplate. Each of these slots serves to accommodate a respective securing lug formed on the gear box. In particular, it can be provided that each of the slots, viewed in the longitudinal direction of the faceplate, has a clear width that corresponds to a transverse dimension of the securing lug in the direction of the longitudinal extent of the faceplate.

[0016] By accommodating the respective locking lug in a corresponding slot in the faceplate, the relative position between the gear box and the faceplate is secured in the longitudinal direction of the faceplate. To easily release the locking of the previously described clip connection, the locking hooks can be accommodated in the respective locking openings with a certain amount of play in the longitudinal direction of the faceplate, without creating any play between the gear box and the faceplate in the longitudinal direction. The invention will now be described purely by way of example with reference to the drawings, in which:

[0017] Fig. 1 a shows an embodiment of a fitting arrangement according to the invention in both a view and a cross-section according to the section line AA;

[0018] Fig. 1 b shows the fitting arrangement of Fig. 1 a before the gear box is attached to the faceplate, also in a view and a cross-sectional view;

[0019] Fig. 1 c shows an intermediate assembly state of the fitting arrangement of Fig. 1 a or 1 b, also in a view and a cross-sectional representation.

[0020] The fitting arrangement 10 according to the invention comprises a gear box 14 and a faceplate 12, to which the gear box 14 is fastened as shown in Fig. 1 a, by means of several clip connections, which are explained in more detail below with reference to Fig. 1 b.

[0021] As can be seen from the cross-sectional views of the figures, the faceplate 12 is essentially a U-profile with two parallel and spaced-apart flanges 22, which are connected to one another by a web 24. A drive rod 16 is guided in the interior of the U-profile along the web 24 in a translationally displaceable manner, which serves in a conventional manner to drive-effectively couple an actuating gear received by the gear box 14 to a locking element, such as a mushroom-head pin and / or a lifting element for raising and lowering a lifting-sliding element.Contrary to the embodiment shown, the gear box 14 can also be the lock case of an additional locking device in which a hook bolt is rotatably mounted and can be pivoted between its locking position and its unlocking position by means of an actuating gear received in the lock case by means of the drive rod 16.

[0022] As already mentioned, an actuating gear is located inside the gear box 14, of which only an input shaft 18 is visible here. This gear can be rotated by means of an actuating lever, for example, between a locking position corresponding to the lowered position of a lifting-sliding element and an unlocking position corresponding to the raised position of the lifting-sliding element. The rotation of the input shaft 18 thus allows the drive rod 16 and, via this, a lifting element coupled to it to raise and lower a lifting-sliding element.

[0023] The following will now discuss in more detail the method of fastening the gear box 14 to the faceplate 12 according to the invention. As already mentioned, the gear box 14 is fastened to the faceplate 12 by means of several clip connections. For this purpose, two locking openings 26 are formed in each of the two flanges 22, spaced apart from one another in the longitudinal direction of the faceplate 12, which serve to receive corresponding locking hooks 28 formed on the gear box 14.

[0024] Specifically, the gear box 14 has two side walls 20 spaced apart from one another perpendicular to the longitudinal extent of the faceplate 12, which side walls 20 are spaced apart from one another by an amount that essentially corresponds to the clear width between the two flanges 22 of the faceplate 12, so that the gear box 14 can be inserted with the free end 34 of the two side walls 20 first into the clear distance between the two flanges 22 or into the interior of the faceplate 12. The locking hooks 28 are formed on the free end 34 of the two side walls 20 and are spaced apart from one another by an amount that corresponds to the distance between the locking openings 26 in the respective flange 22, so that the locking hooks 28 can be received by the locking openings 26 for locking the gear box 14 to the faceplate 12.

[0025] In order to be able to fasten the gear box 14 to the faceplate 12, it is necessary to position the gear box 14 in the longitudinal direction of the faceplate 12 such that the locking hooks 28 are aligned with the corresponding locking openings 26. To facilitate this alignment, two alignment recesses 30 are formed at the free end of each flange 22, which are located at the same position as the locking openings 26 when viewed in the longitudinal direction of the faceplate 12. To mount the gear box 14 to the faceplate 12, the locking hooks 28 can thus first be inserted into the corresponding alignment recesses 30, so that the gear box 14 is already properly aligned in the longitudinal direction of the faceplate 12 for further mounting on the faceplate 12.For the final fastening of the gear box 14 to the faceplate 12, the gear box 14 must therefore only be pressed into the faceplate 12 perpendicular to the longitudinal extent of the faceplate 12 until the locking hooks 28 finally engage in the corresponding locking openings 26.

[0026] Since the locking hooks 28 should be received by the respective locking openings 26 with a slight amount of play in the longitudinal direction of the faceplate 12 so that the respective clip connection is reliably established and can be released again if necessary, the gear box 14 accordingly has a certain amount of play in the longitudinal direction of the faceplate 12 relative to the faceplate 12, provided no further measures are taken to prevent this play. Therefore, in order to keep this play between the gear box 14 and the faceplate 12 as small as possible, in the embodiment shown here, a slot 32 is formed in each of the two flanges 22 between the two locking openings 26, which slot extends perpendicular to the longitudinal extent of the faceplate 12 from the free end of the respective flange 22 in the direction of the web 24 of the faceplate 12.Each of these slots 32 serves to accommodate a respective securing lug 36, which is formed near the free end 34 in the respective side wall 20 of the gear box 14. The clear width of the respective slot 32 essentially corresponds to the transverse dimension of the respective securing lug 36 in the direction of the longitudinal extension of the faceplate 12. By receiving the respective securing lug 36 in the respectively associated slot 32 of the faceplate 12, the relative position between the gear box 14 and the faceplate 12 in the longitudinal direction thereof is thus secured.
