Mobile partitioning wall

The invention relates to a mobile partition with suspended on running rails wall elements and at least one each wall element associated sealing strip according to the preamble of claim 1.

Such partitions are used to selectively space subdivision. The individual wall elements are movable suspended from rails on the ceiling and can be pushed together when not in use on narrow space. Thus, a slight movability of the individual wall elements is guaranteed, due to this. A bottom gap and a ceiling gap A disadvantage is, however, that the sound damping as a result of bottom and top gap are unsatisfactory and usually a groove must be present in a floor guide rail in order to achieve the necessary stability of the wall elements.

Although it is already known (such as in WO-A-8300182 described) the individual wall elements associated sealing rails mechanically to press. This is, however, perceived as cumbersome, particularly if the space division is changed frequently.

With the invention, the task is to be solved to achieve with movable partitions one hand a good soundproof seal and on the other hand, a high level of stability of the individual wall elements while avoiding a bottom guide rail, wherein the tension even with heavy and high wall elements should be carried out simply and quickly.

This object is solved by the characterizing features of claim 1.

This makes it possible to move the wall elements along the rails smoothly and achieve by activating the wall elements associated pneumatic lifting members good stability and high sound insulation. Moreover, the lifting elements of a common compressed air source can be activated effortlessly Only by joining together of the wall elements.

The partition wall includes a plurality of independent, tabular wall elements 1. Each of the wall elements 1 is suspended from a guide rail, which is attached to the building ceiling. Inside the form of a hollow profile running rail 2 there are two carriages with rollers or balls 3, which are connected via a hanger 4 with horizontal cross-beams 5 of the wall element the first The wall element 1 comprises a frame structure made of wood or metal, in particular steel and / or aluminum, with two spaced-apart plates 6, which can consist of different materials, for example steel, aluminum, glass, plaster, wood or plastic. The plates 6 can also be executed in sandwich construction. It is also possible to form the wall element 1 as a steel frame construction with glazing.

In the space 7 between the two plates 6 is located above a ceiling sealing strip 8 and below a bottom sealing strip 9, the two are movable in height. On the two vertical narrow sides of the wall elements 1 is a respective rail 10 available.

The ceiling sealing strip 8 is provided at the top with flexible sealing strips 11, which are intended to be pressed against the running rail. 2 Appropriate flexible sealing strips 12 are also available at the bottom sealing strip 9 and intended to be pressed against the bottom of the 14th The two sealing strips 8 and 9 are connected by a linkage to the two rods 16, 16 'with interposition of a Huborganes 20th Between the sealing strips 8, 9 and the pneumatic lifting member 20 are compression springs 18, which 'surround the rods 16, 16th These compression springs 18 are on the one hand against the two rigidly connected to the longitudinal beams 5 plates and on the other hand against a respective stop 19 of the rods 16, 16 'to, preferably in the form of a disk or a transverse pin. The two compression springs 18 are slightly biased at rest and have the effort said two seals 8, 9 each pulling in its non-sealing position.

The gap in 7 arranged, pneumatically operated lifting device 20 is effective motion in the vertical direction and designed a compressive force to the two seals 8 to exercise. 9 The lifting member 20 is supported in the cavity. 7

3. As can be seen from Fig., The lifting member 20 includes a bellows 22 with vertical movement. The bellows 22 is surrounded by a housing becherartigem 24th Against a support disc 26 held movably at the lower end of the bellows 29 rests on a U-shaped bracket 28, which is connected to the lower rod sixteenth A hose 23 or a pipe opens into the interior of the bellows 22nd As is apparent from Fig. 1, this hose 23 is part of a compressed air line 36 which communicates with pneumatic coupling valves 30, 32. This coupling valves 30, 32 are attached to opposite vertical narrow sides of the wall elements 1 and intended for mutual co-operation, as will be explained in connection with Figs. 4 and 5 in more detail. The first clutch 30 is formed in a conventional manner as a check valve and includes a protruding pin 38, of the flow of the compressed air opens in the interaction with the second coupling member 32, and vice versa when separating interrupts the flow.

The first clutch 30 is secured to a mounting rail 40 by screws 42nd On the mounting rail 40, a sealing cone 44 is moored of elastic material which surrounds the valve body 46th A linearly movable valve member 50 causes during the interaction with the counterpart of an opening of the flow rate for the compressed air. With the compressed air opening 52, the hose or pipe 36 is connected.

The second coupling member 32 includes a flexible sheath 56, preferably made of an elastomer which is retained by the metallic vertical rail 10th In the center is a Supported out by a spring 62 pin 58. The spring 62 is supported in a support 64 and is eager to push the bolt 58 by means of an annular disc 68 upwards. The central bore 66 of the pin 58 opens into the hose or pipe 36th When assembling two adjacent wall elements 1, the valve member 58 penetrates into the valve member 50 and causes a tight connection. Here, the resilient pin 58 is pressed against the spring force. The compressed air thus flows through the hollow pin 38 into the bore 66 of the bolt 58 to the lifting element 20. In the case of a separation of the two wall elements 1, the check valve causes the first coupling part 30 an interruption of the compressed air passage.

According to Fig. 1 is present on at least one wall element is a manually operable decompression valve 34, which causes, upon actuation, the compressed air escapes from the bellows 22nd After decompression lift the two compression springs 18, the sealing strips 8, 9 from the bottom 14 or of the track rail 2 from.

is located on a vertical building wall a wall terminal block with a pneumatic nozzle, which communicates with a usually stationary compressed air source. An air compressor can be located at any point of the building or for example in a ceiling alcove and communicates with the nozzle in flow communication. The to be established by the compressor is preferably about 3-6 bar.

For constructing a partition wall, a first wall element 1 on the running rail 2 will initially be made to abut slidably against a stationary wall connecting strip, thereby opening the associated tap valve, so that compressed air can flow in the direction of arrow C into the conduit 36th Thereby, the bellows is filled 22 with compressed air and moves the rods 16, 16 'is brought into its sealing position in opposite directions, namely, in the directions A and B in Fig. 3. As a result, the two sealing strips 8 and 9 and the position of the wall element 1 fixed between floor 14 and ceiling. Thereafter a further wall element 1 to the first added, said opening by joining the cooperating coupling parts 30, 32 the pressure air flow, and thereby a pressure buildup in the lifting member 30 will cause this adjacent wall member, which also contributes to increase of the respective ceiling sealing strip 8 and leads to the lowering of the bottom sealing strip. 9

When adding further wall elements 1, the process described is repeated. Characterized the wall elements need not be individually connected to a mobile source of compressed air, but the sealing strips 8, 9 can be made by simple push together of the wall elements 1 in the sealing position. After assembly of the wall elements, they are independent of a compressor or another compressed air source. If pressure loss of any wall element the remaining wall elements remain as a result of the check valve under pressure.

To unlock the sealing strips 8, 9, a decompression valve 34 is operated, whereby the lifting member 20 creates a pressure drop. The wall element 1 may thereafter be moved smoothly along the track.

As the wall element 1 itself need not be raised, but only for sealing the two sealing strips 8, 9 are pressed upwards and downwards, it is possible - even for heavy wall elements - to manage with a relatively low pneumatic pressure.

Instead of a bellows 22 is also a commercially available pneumatic piston cylinder assembly could be used in order to achieve a vertical lifting movement of the sealing strips 8, 9 in the supply of compressed air.

A variant consists in each sealing strip 8, 9 to assign a separate bellows or a separate piston-cylinder unit with vertical movement, which are each connected to the common rail 36th

Another variant is that each wall element 1 individually or in groups in any position, can be braced independently of the wall terminal block. In this case, a correspondingly long hose line or a mobile air compressor is required.
