Abstract

The sliding partition has a plurality of movable sections (2, 4) to be fitted on a horizontal guide rail (1). The guide rail (1) determining the travel of the sections (2, 4) from an open into a closed position is laid in a 90° turn in the alignment of the closed partition in the region of the aperture of a space to be enclosed. The last section (2) in the closing direction is borne on bearing and guide components (5, 6), of which at least the rear bearing and guide component (6) in the closing direction is borne on the section (2) in such a way that it can be moved along said section (2). In addition, said rear bearing and guide component (6) has its own drive unit, by means of which the last section (2) can automatically be moved into the closed position aligned with the other sections (4). Between the last section (2) and a closing stop (16) there remains a gap which is to be closed by an additional flap.

Description

Title: Sliding Wall

description

The present invention relates to a sliding wall according to the preamble of claim 1, which has at least two sliding wall elements mounted and movable on at least one stationary horizontal guide rail

Such sliding walls can be used for a wide variety of purposes. In the area of the guide rail, a circumferential driver chain can be provided, by means of which the individual sliding wall elements can be taken in one direction or the other when the drive is switched on. Depending on the use, the individual sliding elements can be used ¬ Wall elements with a closed panel, for example made of wood or metal or with a translucent pane, for example made of glass. With such a sliding wall, a large space can be designed to be subdividable lockable For example in the latter case, the sliding wall for opening or closing the shop must be actuated two or four times a day. When the sliding wall is open, the sliding wall elements are usually arranged with their surfaces parallel to each other in a so-called n Station parked To close the sliding wall, the sliding wall elements can be moved one after the other along the guide rail or the guide rails into the closed position so that, for example, they close a space opening between two walls. One guide rail each can be on the ceiling and on the floor of the room be provided

DE 44 24 660 C1 discloses a horizontal sliding wall in which a further rail system is attached to the ceiling in front of an existing guide rail in which the individual elements can be moved. In this rail system a switchable coupling device that runs with a Identification system is equipped to locate the individual elements, which contain corresponding indicators the entire device is driven by an electric motor that drives an endless belt via a deflection roller. In conjunction with a programmable logic controller, the identification system is controlled in such a way that it recognizes the individual elements after a learning journey and brings them to the desired parking position or to the closed position of the partition. It is also possible to realize only a partial opening in order not to open the entire front area, for example in cold seasons. The switchable coupling device consists of an electromagnet, to the armature of which a slide is attached, which is designed in the shape of a fork in its protruding area in such a way that it detects a connecting pin between the carriage and the element underneath and thus within the guide rails move the entire element according to the selected program. The coupling device and the identification system are supplied with the corresponding signals and the necessary voltage either via sliding contacts or via a trailing cable. The identification system can be a sensor, for example a proximity switch, or optical systems, magnets with corresponding reed contacts or switches can be used

DE 31 48 464 C2 shows a device for moving movably suspended partition walls. For the various partition walls, for example to park them in a corner of a room, there are guide rails which are in cross, T or Y-shape or in arches.

DE 72 47 479 U1 shows an acute-angled branch. One of the two support devices retracts at this branch, the second support device of the wall element being moved further in the straight guide rail.

A similar branch is also shown in DE 21 08 593 A1

The guide rails, which determine the path to be covered by the sliding wall elements from the station to the closed position, are almost always in an arc in the area of the room opening to be closed guided through 90 ° to enable the sliding wall elements to be swiveled in from the park position into the closed position. Because of this curve of the guide rails, the problem arises that the last sliding wall element in the direction of the closing movement must be moved into the space opening until it is completely pivoted into its end position aligned with the other sliding wall elements. For this reason, an open gap remains in the area of said curve of the guide rails, even after the last sliding wall element is in the sliding wall closed position. In the previously known sliding walls, a wide variety of devices have been used to close this gap. It is most common to provide in this area a closing flap that swivels like a door. However, this looks optically disadvantageous and can be regarded as an emergency solution in every respect. It has therefore been proposed to provide an additional separate guide rail for the last sliding wall element, which guides only one sliding wall element into the closed position, which ends in this area and is not guided in an arc into the sliding wall alignment. This solution brings with it some technical problems and, despite the effort involved, is also unsatisfactory.

The object of the present invention is therefore to create a sliding wall which enables complete closing in the area of the last sliding wall element to be transferred into a room opening.

The sliding wall according to the invention corresponds to the characterizing features of patent claim 1. Further developments of the invention are evident from the dependent patent claims.

In order to close a sliding wall in the front without the need for separate locking elements such as flaps or doors, a special arrangement of the guide rails and a special connection of the last sliding wall element to be closed are proposed according to the invention. The arrangement of the guide rails fastened under the building ceiling is not U-shaped, as in the prior art shown in the parking or station area, but in continuation of the closed position, the guide rail is curved in an arc followed by a straight piece running in the parking direction of the other sliding wall elements extended. Only one sliding wall element moves into this arch and the angled piece, namely that which first moves into the parking position. All other sliding wall elements drive with one of their suspensions via a branch into the station. The movement of the individual sliding wall elements can be carried out manually or with motor power. In the following considerations, however, only the motorized version will be dealt with because this brings greater convenience for the operating personnel.

In the motor-driven version, each sliding wall element is equipped with a separate electric motor. According to the invention, the last closure element can be provided with a further drive motor. Drive motors are thus present on both support and guide elements. While a supporting and guiding element is only rotatably connected to the sliding wall element, the second supporting and guiding element can additionally be displaced within the sliding wall element in the longitudinal direction of the element, specifically with a carriage.

If the sliding wall is now to be closed, the sliding wall element parked closest to the building wall is moved last out of the parking position. By driving the electric motor on the non-displaceable support and guide element, the sliding wall element is moved out (pulled) out of the parking position of the station, specifically via the additional arch, in order to get into the guide rail of the front. From a certain position, which is activated by the control for the electric motors, the second electric motor is also energized. As a result, the end of the sliding wall element is additionally pushed and pivoted, namely in that the front edge of the element already presses against the other elements in alignment. At the same time, however, due to the kinematics of the element existing carriage, on which the second drive unit with the second electric motor is flanged, in the direction of the first support and guide element. The result of the arch of the guide rail is that the end of the sliding wall element is printed in the front and thus the front closes

In an embodiment of the idea according to the invention, it is also possible to equip this sliding wall element with an electric motor just like the other sliding wall elements. This electric motor is mounted on the carrying and guiding element, which interacts with the carriage present in / on the sliding wall element. ie this sliding wall element is pulled into the station when the wall is opened and printed out of the station when the wall is closed. However, this is only possible if at least one spring element is present on the carriage. driven position, so from the position in which the front edge of the sliding wall element abuts against the sliding wall element already in the closed position, the electric motor overcomes the force of the spring element and brings the sliding wall element into the closed position, this is due to the Movability of the support and guide element a Also possible when the sliding wall element is at a standstill. In addition to being movable by an electric motor, this can also be done using a linkage or manually

A preferred exemplary embodiment of the subject matter of the invention is described in more detail below with the aid of the drawings

Figure 1 parked sliding wall elements of an open sliding wall

Figure 2 pivoting process of the last sliding wall element in the closed position

Figure 3 shows a drive unit of a sliding wall element

Figure 4 suspension and connection of a sliding wall element

Figure 5 course of the guide rails As is known per se, the nine sliding wall elements 2, 4 in the present example were parked in a train station with the sliding wall open according to FIG. 1. A sliding wall element 2 arranged at the end of a guide rail 1, which is divided into two in the station area, is essential for the invention because it is the last sliding wall element 2 to get into the closed position of the sliding wall. In the area of the room opening to be closed, which is located, for example, between two room walls, of which a room wall 3 can be seen, the guide rail 1 at the end of the front is guided in an arc 21 through 90 ° and then goes in an approximately parallel arrangement 22 Room wall 3 further. So the pivoting of the sliding wall element 2 in the closed position is possible.

The entire course of the guide rails can be seen in FIG. 5. In order to move the number of sliding wall elements 4 into the station, there is a branch 17 from the straight or curved guide rail 1. At branch 17 there is a station entrance 18 with a subsequent bend 19 and a straight guide rail 20.

It should be inserted here that the sliding wall elements 2, 4 can be guided on the ceiling 3 as well as on the floor. The ceiling-side guide rail 1 is more complex, however, since the sliding wall elements 2, 4 are suspended from it and the drive is also located here in the case of elements which can be moved by motor.

The sliding wall elements 4 are suspended from at least two support and guide elements 5, a drive unit being present on at least one support and guide element. In addition to the carrying and guiding element 5, the sliding wall element 2 has a further carrying and guiding element 6. A drive unit (not shown) is located on the carrying and guiding element 5 and is intended to convey the sliding wall elements 2, 4 into the room opening in a known manner. The second support and guide element 6 in the closing direction has a second additional drive unit, ie the sliding wall element 2 is always provided with two drive units. The guide rail 1 is, according to the present example, essentially C-shaped and fastened to the ceiling by means of a ceiling fastening 28. The upper end of the sliding wall element 2 is mounted on it by means of the respective support and guide elements 5 6, which have at least one support roller 7 and Have guide roller 23 The drive for the drive unit is provided by an electric motor, which is preferably designed as a direct current motor. On the drive axis there is an anti-spike 8 which is intended to engage in a toothed belt 9 which is fixedly arranged on the guide rail 1. The toothed belt 9 extends over the length of the guide rails. The support and guide elements 5, 6 can therefore be moved along the guide rails 1, 17, 18, 19, 20, 21, 22 by rotating the actuating element 8. The power supply and control of the auxiliary motors takes place via a current, not shown, running parallel to the guide rails rail using pantographs

In particular, the second support and guide element 6 is designed such that this not only along the guide rail 1, but also, albeit in a limited area, in a guide channel 10, which is located within an end profile 26, along the upper edge of the sliding wall element 2 is movable. For this purpose, the carrying and guiding element 6 is provided with at least one roller 11 which can be moved in the guiding channel 10. In the present example, a total of eight rollers 11 are provided, the guiding channel 10 being shaped such that the sliding wall element 2 is suspended For this purpose, the guide trough 10 has two lateral depressions 12 which extend over its longitudinal direction and in which the rollers 11 can be moved. The carriage 13 of the rollers 11 is designed such that it is rotatably mounted on a bolt 14 , which in turn is connected to the part of the carrying and guiding element 6 via a lock nut 25 which includes the rollers 7 to be engaged in the guide rails 1, 21, 22

When the sliding wall is closed, the individual sliding wall elements 4 are moved into the closed position one after the other. As can be seen from FIG. 2, the last sliding wall element 2 now comes into the area The opening to be closed, that is to say in the area of the arch 21 there of the guide rail 1, the following occurs: after the first support and guide element 5 in the closing direction has passed the guide rail arch 21 and is located on the straight line of the guide rail 1, which defines the closed position of the sliding wall, the second, up to that point retracted support and guide element 6 comes to the beginning of the curve. The electric control of the electric motor of the support and guide element 6 which drives the pinion 8 is now controlled in such a way that the sliding wall element 2 is pushed from behind in the closing direction. The sliding wall element 2 is in contact with the preceding sliding wall element 4 with the front edge, or it is braked by appropriate activation of the first supporting and guiding element 5. The second support and guide element 6, which moves along the arc 21 out of the guide rail 22 and subsequently in the guide rail 1, also moves forward within the guide groove 10 on the upper edge of the sliding wall element 2 such that the distance between the support and guide element 6 and the rear edge of the sliding wall element 2 is increased. As a result, as illustrated by an arrow, this rear edge 15 is pivoted so far until it abuts a closing stop 16 fastened to the room wall 3. Now the sliding wall element 2 arriving last during the closing process is pivoted completely into its end position aligned with the other sliding wall elements 4. In the area of the closing stop 16 there is no longer any open gap which could be closed with flaps or other aids. The lateral closure of the sliding wall therefore looks optically very advantageous both when the sliding wall is open and when it is closed. In the area of the closing stop 16, locking bolts can also be provided in a simple manner, so that the proposed sliding wall also offers safety-related advantages. However, it is also possible to ensure the closure of the sliding wall by preferably preferably electrically releasable locking off of the carrying and guiding element 6. The sliding wall is preferably designed such that not only the carrying and guiding element 6, but at least the rear carrying and guiding element of the remaining sliding wall elements 4 in the closing direction can be moved along the upper edge of the respective sliding wall element, particularly in the station area according to FIG achieve when moving and compactly parking the sliding wall elements. The so-called train station can be located either in the area of the room opening to be closed, so that when the sliding wall is open, the sliding wall elements 2, 4 lie parallel to one of the room walls or also to the side behind a corner or even in a separate room It goes without saying that analogous to the described ceiling-side guide rail of the support and guide elements, a guide can also be provided in the floor area. It is also within the scope of the invention, the sliding wall in the individual tech niche differently than in the previously described preferred exemplary embodiment

The sliding wall elements 2, 4 described above can be made from a wide variety of materials. However, in the case of business fronts, the end profile 26 is provided with a glass pane 27
