Description

Hardware arrangement

The present invention relates to a fitting arrangement for a lift-slide element such as a lift-slide door or a lift-slide window, which comprises a frame and a wing that can be displaced along a track in a direction of displacement with respect to the frame a base part which is designed for fastening to the wing, at least one carriage which has a carriage frame and at least two running rollers mounted on the carriage frame, and a bracing mechanism for lifting the wing relative to the carriage frame from a lowered position into one raised position, wherein the fleece mechanism comprises a first inclined guide, by means of which the carriage frame is guided displaceably on the base part in a direction extending obliquely to the displacement direction.

Such lift and slide elements are becoming increasingly widespread, for example in the form of large terrace doors or windows. The direction of displacement is horizontal when the lift-slide element is installed. Frequently, with such lift-slide elements, several carriages are arranged on the underside of the wing, the rollers rolling directly on a lower track. In principle, one or more carriages could also be arranged on the top of the wing, the rollers rolling on a hanging rail. In such a configuration, a lower raceway can be provided as a setting surface. It can also be provided that the underside of the wing sits on the running track in the lowered position. By actuating the lifting mechanism, the wing can be raised in relation to the carriage frame be, whereby an air gap is formed and the wing can be moved by means of the rollers.

The carriage frame can be any carrier for storing the rollers. This means that the car frame does not necessarily have to be frame-like in the sense that it has a closed shape. For example, the carriage frame could be formed by two flat bars spaced apart from one another, which are connected to one another by a spacer or also by the axes of the rollers.

The first inclined guide converts a horizontal adjustment movement of the carriage, which is brought about, for example, via a drive rod arrangement and possibly via a corner deflection, into a lifting or lowering movement of the wing. It should be pointed out that the term "inclined guide" does not necessarily mean a guide with a straight, oblique guide course. Rather, an oblique guide is to be understood as a guide whose guide course is not parallel and not at right angles to the direction of displacement. The inclined guidance can thus also run as a whole as long as infinitesimal sections of the relevant guideway are inclined to the direction of displacement.

In practice, when lifting and lowering the sash, an unfavorable force can be exerted on the carriage. In particular, an uneven loading of the two or more rollers can occur. For example, depending on the point of engagement of a drive rod mechanism on the carriage frame and the corresponding pulling or pushing direction, the foremost or rearmost roller can be subjected to increased loads. This causes an uneven wear of the rollers, which leads to a noticeably changed sliding behavior of the lift-slide element from a certain extent. The carriage is then usually to be replaced, which is expensive and troublesome. It is an object of the invention to improve the robustness of lift-slide elements and to reduce the maintenance effort.

The problem is solved by a fitting arrangement with the features of claim 1.

According to the invention, the lifting mechanism comprises a second oblique guide that is separate from the first oblique guide, by means of which the carriage frame is guided on the base part in a direction obliquely to the direction of displacement or on another fitting part designed for attachment to the wing.

Because of the two inclined guides, the carriage is guided more reliably and is loaded more evenly, in particular when lifting and lowering the sash, than is the case with conventional fitting arrangements of the type mentioned at the beginning. The additional inclined guide stabilizes the carriage frame during its movement in such a way that an uneven load on the rollers is counteracted. If necessary, more than two inclined guides can also be provided for guiding the carriage.

The first oblique guide and the second oblique guide preferably define parallel guide directions. This means that the guideways defined by the first oblique guide and the second oblique guide preferably run parallel to one another. As a result, the movement of the carriage during the raising and lowering of the sash is always performed twice.

The second inclined guide can be designed as a sliding guide. Alternatively or additionally, the first inclined guide can be designed as a sliding guide. Slideways are relatively inexpensive to provide. However, should the If a particularly high guide accuracy or particularly low wear are required, the first oblique guide and / or the second oblique guide can be designed as a roller guide. The first inclined guide and / or the second inclined guide can comprise at least one inclined surface formed on the carriage frame, which cooperates with a guide element arranged on the base part. This enables a particularly simple and inexpensive construction. The guide element can be attached to the base part or can be formed in one piece with it. In particular, the guide element can be a simple sliding piece.

It can be provided that a counter inclined surface is formed on the guide element, which extends at least substantially parallel to the inclined surface formed on the carriage frame. The inclined surface and the counter-inclined surface lie against one another and thus enable stable and secure guidance.

According to one embodiment of the invention, the inclined surface is formed on an underside of the carriage frame. A guide element, which is supported on such an inclined surface, holds the carriage frame downwards, so that a roller located in the region of the guide element is protected against excessive stress.

A further embodiment of the invention provides that the guide element has a support which is guided through the carriage frame from above and has at least one lateral projection, preferably with two lateral projections. This enables particularly easy production. The cantilever can slide or roll along the sloping surface of the carriage frame. According to a further embodiment of the invention, the carriage frame comprises two lateral support sections, between which the at least two rollers are arranged, with respective inclined surfaces of the second inclined guide being formed on both lateral support sections. The mechanical stability of the second inclined guide is relatively high in this embodiment despite the simple construction. The inclined surfaces provided on the support sections can, in particular, interact with opposing projections which are arranged on a support as described above.

The base part can be at least essentially L-shaped and / or can be provided for fastening to a lower corner region of the wing. This configuration is particularly suitable for the use of a fitting arrangement according to the invention with existing lift and slide elements.

A further embodiment of the invention provides that the first inclined guide and / or the second inclined guide comprises a guide link running obliquely to the direction of displacement and a support element guided in the guide link, the guide link on the base part or on the further part for attachment to Wing formed fitting part is formed and the support element is arranged on the carriage frame. The support element can be designed as a sliding pin or as a rotatable roller. It has been shown that such an inclined guide is well suited to absorbing the low load when guiding.

In principle, the first oblique guide and the second oblique guide can be configured identically. However, in order to limit the manufacturing costs, it is preferred that the second inclined guide is simplified compared to the first inclined guide, that is, for example, only guiding or supporting in one direction. It is preferably provided that the support element is arranged between the rollers. This enables a particularly simple construction.

The second oblique guide is preferably spaced from the first oblique guide with respect to the direction of displacement. This results in a particularly favorable exertion of force.

A fitting arrangement according to the invention can comprise at least one drive rod, by means of which the lifting mechanism can be actuated. The drive rod can be connected to the car frame via a corner drive.

The invention also relates to a lift and slide element, in particular a lift and slide door or a lift and slide window, with a frame, a wing that can be displaced along a track in a direction of displacement with respect to the frame and a fitting arrangement, in particular one as described above, the fitting arrangement comprising at least one base part fastened to the wing, at least one carriage which has a carriage frame and at least two running rollers mounted on the carriage frame, and a lifting mechanism for lifting the wing relative to the carriage frame from a lowered position to a raised position, the lifting mechanism comprising a first inclined guide, by means of which the carriage frame is guided displaceably on the base part in a direction extending obliquely to the displacement direction. According to the invention, the lifting mechanism comprises a second oblique guide separate from the first oblique guide, by means of which the carriage frame is guided displaceably on the base part or on a further fitting part fastened to the wing in a direction inclined to the direction of displacement. An underside of the wing can be spaced from the track by an air gap when the wing is in the raised position.

Further developments of the invention are also specified in the dependent claims, the description and the accompanying drawings.

The invention is described below by way of example with reference to the drawing. 1 shows a side view of part of a fitting arrangement according to a first embodiment of the invention, a base part of the fitting arrangement being in a lowered initial state. FIG. 2 shows the fitting arrangement according to FIG. 1 with the base part raised.

FIG. 3 shows the fitting arrangement according to FIG. 2 with the base part raised further.

4 shows a side view of part of a fitting arrangement according to a second embodiment of the invention.

FIG. 5 shows the fitting arrangement according to FIG. 4 in a cut-away view.

Fig. 6 shows a guide element of the fitting arrangement according to

Fig. 5 in an enlarged partial view. 1 to 3 show part of a fitting arrangement 11 according to the invention, which comprises a base part 13. The base part 13 is designed for attachment to a wing of a flebe sliding door, not shown. In the exemplary embodiment shown, the base part 13 is at least essentially L-shaped because it is provided for direct attachment to a lower corner region of the wing. However, this is not mandatory. Basically, the base part 13 could also be designed for indirect attachment to the wing.

For a displacement of the wing in a displacement direction V, the fitting arrangement 11 comprises a carriage 17, which comprises a carriage frame 25 and two rollers 27 rotatably mounted on the carriage frame 25. When the wing is displaced, the rollers 27 roll on a track, not shown, arranged below the wing. The fitting arrangement 11 can have one or more further carriages in a manner known in principle to form a coupled carriage arrangement, which is not shown in FIGS. 1 to 3, however. The direction of displacement V runs parallel to the longitudinal extent of a mounting surface 28 of the base part 13, which is assigned to the underside of the wing.

For raising and lowering the sash, the fitting arrangement 11 comprises a lifting mechanism 30 which can be actuated by a drive rod 33 and brings about a raising and lowering of the base part 13 relative to the carriage frame 25. The drive rod 33 is coupled to the carriage 17 via a corner deflection 34 and a coupling lever 31.

Furthermore, the lifting mechanism 30 comprises a first inclined guide 35 for converting a horizontal movement of the carriage 17 caused by the drive rod movement into a vertical movement of the base part 13. In the example shown, the first inclined guide 35 comprises a base part 13 which extends obliquely to the direction of displacement V. Leadership backdrop 38 and a support element guided in it and arranged on the carriage frame 25, of which only the axis 39 is visible in FIGS. 1 to 3. As shown, the support element is arranged between the two rollers 27. When the drive rod 33 is actuated, the support element 39 moves in the guide link 38, as a result of which the carriage frame 25 is raised or lowered relative to the base part 13.

In order to counteract an uneven load on the rollers 27, the lifting mechanism 30 comprises a second inclined guide 45, the guide path of which runs parallel to the guide path of the first inclined guide 35. The second inclined guide 45 is formed by two on the carriage frame 25

Inclined surfaces 47 and a guide element 49 cooperating with them are formed. As shown, the inclined surfaces 47 are formed on an underside 55 of the carriage frame 25, specifically on two lateral support sections 57 of the carriage frame 25, which are preferably designed as flat iron.

The guide element 49 comprises two lateral projections 59 which slide along the inclined surfaces 47. The lateral projections 59 have counter-inclined surfaces 60 which run parallel to the inclined surfaces 47. In principle, the guide element 49 could also be a separate component which is fastened to the base part 13 or to a separate fitting part of the fitting arrangement 11.

If, starting from the state of the fitting arrangement 11 shown in FIG. 1, the user moves the drive rod 33 upwards by actuating a handle or the like, the coupling lever 31 pulls on the carriage frame 25 and thereby moves the carriage 17 relative to the Base part 13 in the direction of the corner deflection 34, that is to the left in the picture. The first inclined guide 35 ensures that this displacement movement is accompanied by a lifting of the base part 13 relative to the carriage 17, as shown in FIG. 2. When the fitting arrangement 11 is mounted, the wing rises here. The lifting process is ended when the final state shown in FIG. 3 is reached.

Due to the fogging conditions given by the corner deflection 34 and the coupling lever 31, without the second inclined guide 45 during the lifting process, the roller 27 on the left in the picture would be subjected to a greater load than the roller 27 on the right in the picture. The second inclined guide 45 ensures, however, that the additional force acting on the left roller 27 in the picture is absorbed and thus both rollers 27 are equally loaded. This prevents one-sided wear.

4 to 6 show an alternative embodiment of a fitting arrangement 11 'according to the invention. This is designed similarly to the embodiment shown in FIGS. 1 to 3, but in contrast to this has a second inclined guide 45 ', which is spaced from the first inclined guide 35 with respect to the direction of displacement V. In particular, the second inclined guide is arranged on a front end region 65 of the carriage 17 facing the corner deflection 34. The front part of the carriage 17 can thereby be supported or guided particularly effectively downwards. As can be seen in particular in FIGS. 5 and 6, the guide element 49 'comprises a support 67 which is guided through the carriage frame 25 and from which two lateral projections 59 protrude. These are provided with counter sloping surfaces 60.

In principle, the second inclined guide 45, 45 ', like the first inclined guide 35, could be designed as a link guide. A design as roller guide, dovetail guide and the like is also possible. A single-sided oblique guide 45, 45 'formed by inclined surfaces 47 of the carriage frame 25 and a guide element 49 sliding along it can, however, be produced particularly easily and inexpensively. It should be pointed out that in both embodiments the second inclined guide 45, 45 ′ could also guide the carriage frame 25 on a fitting part separate from the base part 13, which in turn is designed for fastening to the sash.
