Description

Title: Sliding Wall

description

The invention relates to a sliding wall with a plurality of laterally displaceable wall elements which are guided by means of rollers on a support profile arranged above the wall elements. At least one of these wall elements is designed with a drive for actuating the wall element as a rotating wing, the drive being arranged in a stationary manner with respect to the displaceable wall element. There is an actuating means between the drive and the rotary wing, which can become automatically effective and ineffective by a linkage when moving the wall elements.

DE 199 59 825 C1 describes a sliding wall with a plurality of laterally displaceable wall elements which can be displaced along a slide rail by means of rollers. At least one wall element is designed as a rotary wing that can be actuated via a door closer, an automatically coupling or decoupling slide rail linkage being arranged between the door closer and the wall element serving as a rotary wing. The arrangement of the individual wall elements with each other is realized by fittings. This means that when moving the sliding wall with all its elements, they must always be moved as a whole. Such a sliding wall thus receives a correspondingly high degree of stability with one another. Furthermore, a locking member is provided, by means of which the rotary wing can only be actuated when the entire sliding system is in the closed position. In this position, the fixed mounted swing door drive is released. The suspension is relieved by the design of the suspension of the rotary wing, namely not on the displaceable and rotatable wall element, since the weight of the drive device is accommodated in a building-fixed manner. The object of the invention is to further develop the prior art in such a way that a drive according to DE 199 59 825 C1 can be used in any type of sliding wall.

The solution to the problem is that a sliding wall, consisting of individual manually or motor-driven wall elements, on the one hand has a floor guide, which is guided in particular in the case of a wall element which is designed as a rotating wing, at the upper and lower end of the wing. In addition, the rotary wing has a first pivot axis and a second pivot axis in order to give the rotary wing appropriate stability during a rotary movement. Furthermore, the individual wall elements are automatically coupled to one another at the moment when they form a closed front with one another, so that the pivoting wing can be pivoted safely.

This object is achieved according to claim 1 with the features specified there. The subclaims show advantageous developments of the invention.

In order to form a first and second pivot axis, the rotary wing is equipped with at least one lever arm. In addition, the rotary wing is guided in an upper and a lower end region by means of the guide elements already mentioned in a floor rail or a ceiling support rail. By means of this arrangement according to the invention, the rotary wing pivots both about the lever arm and also about the guide elements which are moved in an upper additional guide rail with continuous pivoting of the door wing element. The main closing edge of the rotary wing follows the path of an ellipse. The pivoting movement is given sufficient stability by a so-called three-point bearing, namely a guide in the upper and lower region of the wall element. The lever arm used can be hinged to an upper and lower door leaf end. However, it is also possible for the rotary element to have only one lever arm arranged above or below.

In order to provide a particularly compact structure, the lever arm or arms of the wall element (rotating wing) are preferably arranged in a recess provided in a wing profile.

A running rail is particularly preferably arranged in a suspension profile. A carriage is preferably introduced movably in this running rail. The carriage is preferably connected to the rotating wing of the wall element by means of a pendulum holder. It should be noted that in this embodiment according to the invention the wall element encompasses both the door wing and the suspension profile and the wing profile which is in direct connection with the wing.

In order to obtain a secure rotating wing element, a locking device is preferably provided, which is designed as a coupling and locking member at the same time. As a result, the wall element according to the invention can be locked with an adjacent wall element without the usual locking in the floor. This ensures that the door is operated safely.

In order to avoid generating any additional stresses when pivoting the rotating leaf, the guide elements of the rotating leaf are arranged in the rails approximately in the middle of the width of the door leaf. Thus, there is also a focus when pivoting the door leaf in the middle of the door leaf. The aforementioned connecting device can consist of two mutually corresponding sub-elements, each of which is integrated on or in two abutting wall elements.

For example, a first partial element, consisting of a flat arm in the form of a coupling element, can be integrated in a wall element that cannot be pivoted. At its end, the coupling element has a coupling bolt which cooperates with the second partial element, which is contained in the wall element to be pivoted. Such a second sub-element can consist of a fixing element and a locking element at the same time.

If two wall elements move towards each other, one is designed so that it contains a rotating wing and the other is designed as a pure wall element, locking is only carried out if one pushes against the rotating wing or due to the drive described above Movement of the rotary wing is initiated. The rotary wing is locked with the adjacent wall element via a lever arm. Such a locking element can essentially consist of a connecting element which is provided with a bore into which the coupling bolt of the adjacent wall element engages when actuation (rotation of the rotary wing) takes place. In order to achieve an exact adjustment, an adjustment screw is available which enables the connection element to be adjusted.

In order to lock the two wings together, a coordination element is provided which has one or two locking bevels in one end region. These locking bevels are designed in such a way that the bevels fall off towards the outer edges and there is a flat unlocking surface in their central region. The adjustment screw also acts as a release element for the locking element, since the end of the adjusting screw rests on the unlocking surface. If the pivoting wing is pivoted, the adjusting screw slides down on one of the locking bevels, which at the same time means a lowering of the connecting element. In the correct position, the coupling pin can thus dip into a bore within the connecting element, which means that even when the rotary wing is pivoted slightly, the two adjacent wall elements are immediately connected to one another. For better threading into the lever arm, it is provided with a tapered opening at its end so that the coupling pin is automatically brought into the correct position.

The coupling bolt also fulfills a fixation of the wall elements to one another in such a way that an opposite end of the coupling bolt can be inserted into a coupling opening of the coordination element. This coupling opening has a conical shape that tapers towards the rear. From a certain depth, however, the coupling opening widens, specifically to give the coupling pin enough opportunity to come out of the coordination element again when the pin is pivoted as described above.

In a further embodiment of the invention, the lever arm has a second locking possibility at its opposite end, on which the locking element is located. This consists of a semicircular element which has a notch in its central region which interacts with an element which is fixedly connected to the lower profile of the rotary wing. This locking has the task of holding the lever in its zero position when no coupling is made with an adjacent wall element. A sliding wall as described above can be automatically moved from a parking position into the use position without additional handles. At the same time, a rotary sash can be actuated in the use position without manual forces. The position of such a wing depends on whether an appropriate automatic drive is installed in the ceiling area. Such an automatic drive can be installed practically anywhere in the system. This increases the flexibility of such sliding walls enormously.

The design of the wall elements according to the invention is used in particular with wall elements made of glass. However, it goes without saying that such constructions are also possible with wall elements made of wood, metal, plastic or any type. Thanks to the integral installation within a sliding wall using rotatable wall elements, such a wall element can be completely pre-assembled in the factory, so that only minimal assembly work is required on the construction site. It is therefore only necessary to insert the door element into the upper and lower guide rails at the construction site.

The invention is described below with reference to the figures by an embodiment. The drawings show a schematically illustrated embodiment. Things that are not relevant to the invention have been omitted if they are not necessary for understanding.

A sliding wall shown in FIG. 1 consists of a plurality of wall elements, which in the exemplary embodiment consists of two displaceable wall elements 1 and a displaceable and pivotable wall element 2. The wall elements 1 are arranged adjacent to the wall element 2. The wall elements 1 are by means of connections 4 via a fastener 3 and a carriage 18 slidably arranged within a support profile 8. The wall element 2 has a similar connection, but instead of the fastening profile 3, a suspension profile 44 has been used in the upper region. The connection to the support profile 8 is realized in the same way as for the sliding wall elements 1.

In the lower area of the wall elements 1, 2 there are lower end profiles 5, in which floor guides 9 and 57 are provided, directed towards the floor. The floor guides 9, 57 engage in a guide rail 7 embedded within the floor, which is not designated in any more detail. This ensures that the wall elements 1 and 2 can be moved safely.

Within the lower end profile 5 of the wall element 2 there is a lever arm 13 which has a pivot bearing 10 at one end and includes a pivot axis 15 at a further end.

Below the suspension profile 44 there is a wing profile 11 on the wall element 2. A lever arm 12 is mounted on one side on the wing profile 11 via a pivot axis 14 and on the other side via a further pivot bearing 10 on the suspension profile 44 located above.

The floor guide 57 is at the same time a first pivot axis, which is arranged approximately centrally in the wall element 2. A pivot axis 19 is located at the upper end of the airfoil 11 in the aligned axis.

In an embodiment of the invention, in addition to the first pivot axis 19, 57, there is a second pivot axis for the lever arms 12, 13 with their ren pivot axes 14, 15. The pivot axes 14, 15 are also aligned one above the other.

The exemplary embodiment of a sliding wall in FIG. 2 shows in the left area a wall 16 from which a support profile 8 extends in any shape. The support profile 8 ends opposite the wall in a station in which the individual wall elements 1, 2 can be parked, namely when the sliding wall is open. In the illustration, the sliding wall is closed, so that the individual wall elements 1 and 2 remain in their position of use. In the area where the wall elements 2 are arranged, there is a drive 55 above, namely in the area of the support profile 8. The drives 55 are stationary and are not moved with the sliding wall. The schematic representation in FIG. 2 shows the opening sequence of the wall elements 2.

FIG. 3 shows how such a drive 55 works together with the wall element 2 as a rotary wing. In this lateral and partially sectioned illustration, the drive 55 is connected in a stationary manner to the support profile 8 and the carriages 18 contained therein via the connection 4 to the suspension profile 44. Below the suspension profile 44 is the wing profile 11, to which the glass element of the wall element 2 is attached. In order to be able to accomplish the rotatability of the wall element 2, the pivot axis 19 is connected to a carriage (not shown) with a pendulum suspension within a slide rail, which is located in the suspension profile 44.

On the side of the wing profile 11 is a slide rail 60, the one

Has groove 61. A pin 59 engages within the groove 61 and can also be provided with a roller. The pin 59 is arranged at one end of a flat arm 56 of a linkage, the other end of the Flat arm 56 is non-positively and positively connected to an output shaft of the drive 55.

If the drive 55 is actuated in the position shown in FIG. 3, the output shaft 58 would execute a rotational movement, which means at the same time that the flat arm 56 would pivot the rotating wing 2 due to its coupling to the slide rail 60. The drive 55 can be controlled by a manual signal or a sensor signal.

It can also be seen from FIG. 3 that when the wall element 2 is moved in connection with the pin 59, the flat arm 56 is automatically coupled or uncoupled to the slide rail 60. The drive 55 can thus be connected to the wall element 2 ready for use without the need for manual actuation.

As can be seen from FIG. 1, the displaceable and pivotable wall element 2 comprises an upper actuating arm 12 and a lower actuating arm 13, which are designed as levers. The upper arm 12 is rotatably supported via the pivot axis 14, which is articulated on the wing profile 12. Furthermore, the upper lever arm 12 is supported at the other end on the rotary bearing 10. This forms an axis of rotation in the suspension profile, about which the lever arm can rotate. For a construction that is as compact as possible, the upper lever arm 12 is arranged within a free cut in the suspension profile 44, which is not specified in more detail.

The wall element 2 thus comprises three pivot axes, namely the

Pivot axis in the area of the pivot bearing 10 on the side of the suspension profile 44, about which the actuating arm 12 pivots, and the actual pivot axes of the wall element 2, namely the first pivot axis 19, 57 and the second pivot axis 14, 15.

The lower lever arm 13 is also aligned at a free end with the pivot bearing 10 due to a coupling bolt 26 to be described later, which is located in a coupling element 20. At its opposite end, the lever arm 13 is connected to the wall element 2 via the second pivot axis 15 already described. In this case, the lower lever arm 13 is likewise arranged in a free cut in the lower end profile 5, which is not described in any more detail.

How the adjacent wall elements 1 and 2 are connected to one another is shown in FIGS. 4 to 7. 4 shows the displaceable wall element 1 with the coupling element 20 on the right-hand side, the coupling element 20 protruding from the displaceable wall element 1. The coupling element 20 is designed as a flat component. Within the wall element 1, the coupling element 20 is non-positively and positively fastened within a recess 21. In the area of the free end of the coupling element 20, the coupling bolt 26 is non-positively and positively connected to the coupling element 20 via a weld seam 39. Coupling pin 26 points out of coupling element 20 on the one hand with its coupling projection 42 and on the other hand with a latching end 37.

The pivotable wall element 2 is shown on the left side of FIG. The lever arm 13 is arranged in a pivotable manner within a section that is not designated in any more detail. Within the lever arm 13 there is a connecting element 25 which is supported on one side. The connecting element 25 can preferably be made from a spring steel. The coupling element 20 is immersed in this when it approaches the pivotable rotary wing 2 and thus on the lever arm 13. sen, as shown in Figure 5. When the coupling bolt 26 is seated correctly within a coordination element 28, which is arranged above the lever arm 13 in the end region of the wall element 2 on the underside, a coupling-out cutout 32 is present. The illustration in FIG. 5 shows that the coupling attachment 42 interacts with a bore 27 within the connecting element 25. If the connecting element 25 were lowered, the coupling projection 42 would thus dip into the bore 27. This would mean that the adjacent wall elements 1 and 2 are connected to one another and at the same time a pivot axis in alignment with the pivot bearing 10 in the upper region of the wall element 2 would be formed.

The coordination element 28 has been reproduced in FIG. 9 in a perspective view. In this case, the coordination element 9 has, at one end in the exemplary embodiment 2, locking bevels 29 directed towards one another, each of which slopes towards the edge of the coordination element 28. In the area where the locking bevels 29 would meet, there is an unlocking surface 30. The unlocking surface 30 coordinates with an adjusting screw 24, which is screwed inside the connecting element 25. The free end of the adjusting screw 24 protrudes beyond the lever arm 13 and comes to rest on the unlocking surface 30 when the wall elements 1, 2 are aligned. This position can also be seen in FIGS. 4 and 5. With a slight pivoting of the wall element 2, the end of the adjusting screw 24 would slide over one of the two locking bevels 29, depending on the pivoting direction of the wall element 2, which would simultaneously cause the connecting element 25 to pivot. The pivoting is initiated at the moment when the drive 55 effects the opening process of the wall element 2 after corresponding coupling of the wall element 1 to the wall element 2. The coordination element 28 is fastened via bores gene 34, which ensure the proper fit of the coordination element 28 with the lower end profile 5 by screw 33.

At its other end, the coordination element 28 has a coupling opening 31 through which the latching end 37 of the coupling bolt 26 passes. In order to achieve a better threading, the coupling opening 31 has run-in bevels 35 which taper conically towards the center of the coordination element 28, i. H. taper. From a certain area, there are outlet bevels 36 following the inlet bevels 36, which run conically in the opposite direction. The outlet bevels 36 end in the coupling cutout 32.

The interaction of the coordination element 28 and the connecting element 25 with the coupling element 20 and the coupling bolt 26 creates a device for coupling and at the same time execution to form a locking member which, even with a small pivoting of the wall element 2, secures the wall element 2 in place Position.

FIG. 7 shows a rotation and at the same time pivoting about the pivoting directions 46, 47 of the wall element 2 relative to the wall element 1. Here it can be seen that a tip of the adjusting screw 14, which is not specified in more detail, projects from the lever arm 13 through an elongated hole in the form of an opening 45 from the lever arm 13. Furthermore, the lever arm 13 has at its free end in the region of the connecting element 25 a conical inlet 48 in order to achieve a better threading of the coupling bolt 26.

The arrangement of the coupling pin 26 and its nature can be seen in FIG. 8. The latching end 37 is inside the coupling entes 20 inserted and connected by a weld 39 with this non-positively and positively. An attachment 38 is present above the coupling element 20. Following the shoulder 38, a truncated cone 40 is shown with an adjoining surface 41 and a further truncated cone 40, the last-mentioned truncated cone merging into the coupling shoulder 42. The truncated cones are there to make it easier to thread into the lever arm 13 and also into the coordination element 28.

The perspective view of FIG. 10 shows the lever arm again separately. The lever arm has the connecting element 25 in its left end region and an additional locking possibility for the lever 13 in its right end region, so that the lever 13 does not move out of its position of use when the wall element 2 is moved. The locking device consists of an end piece 50 which has a semicircular shape 50 on its outer region, which includes a notch 52 in its central region. A locking bolt 54 (FIG. 7) cooperates with the notch 52 and is contained in a threaded bore 53 of an angle 49. The angle 49 is attached to the lower end profile 5 in a non-positive and positive manner.
