Description

The invention relates to a bracing system for a in a mobile wall system by means of at least one movable Ausfahrdruckschuhs horizontally and / or vertically bracing mobile wall element. Furthermore, the invention relates to a mobile wall element with a bracing system, the use of a bracing system in a mobile wall element and a mobile wall system with one or more mobile wall elements.

Mobile wall systems, also known as partition systems, are used for the variable subdivision of rooms. Known mobile wall systems have a usually mounted in the ceiling guide rail and possibly a floor mounted guide rail and flat mobile wall elements that can be moved out of a rest position in which they take up little space, and assembled into a complete partition and vice versa.

The individual mobile wall elements are clamped by means of movable elements, so-called Ausfahrdruckschuhe between ceiling and floor. The Ausfahrdruckschuhe are sunk in the non-actuated state wholly or partially in the mobile wall element. In the extended state they protrude beyond the mobile wall element and are pressed against the ceiling or floor or ceiling rail or bottom rail. In the context of the invention, the ceiling rail can be regarded as part of the ceiling and accordingly the bottom rail as part of the floor.

In known tension systems, the extension pressure shoes are connected to metal bars which are moved apart or towards each other by means of a scissors mechanism to extend or retract the extension pressure shoes. By extending the or the Ausfahrdruckschuhe the mobile wall element between the ceiling and floor is braced.

Mobile wall systems optionally comprise further mobile wall elements, so-called telescopic elements, which, in addition to a vertical tension between ceiling and floor, still permit horizontal tension by means of a further, laterally arranged, extension pressure shoe. This requires a complicated mechanism with more metal rods. With telescopic elements mobile partitions are sealed from several mobile wall elements.

In these telescopic elements, the tensioning systems have a scissors mechanism, via which the pressure is exerted on all the extension pressure shoes. The telescopic elements can be clamped simultaneously vertically and horizontally. This can lead to tension and tilting in the mobile wall element.

The mobile wall elements of the prior art, in addition to one or more Ausfahrdruckschuhen and the linkage of the tensioning mechanism on a housing with a frame and two Verblendungswänden. In this case, the tensioning mechanism is not visible from the outside.

For a secure clamping of the mobile wall elements, it is necessary that the Ausfahrdruckschuhe exercise along its extension a uniform contact pressure on the ceiling, the floor and possibly the side. In order to minimize the number and weight of the metal bars, the metal bars of the tensioning mechanism are centrally mounted inside the mobile wall element, so that the metal bars form a cross shape with a scissor mechanism as a crossing point in the center of the mobile wall element. This consumes much space in the surface of the mobile wall element. Thus, it is hardly possible to provide openings for wicket doors or windows in conventional mobile wall elements with cross-shaped tensioning mechanism.

The tensioning mechanism requires strong pressure on the extension pressure shoes. This means that the metal bars must be very stable. Conventional tensioning mechanics are therefore difficult.

In tensioning mechanics occur relatively high friction losses. To overcome the friction, it is known to provide electrical systems in addition to crank systems. These systems also have mechanical emergency functions in some cases.

In DE 198 11 537 A1 is a wall element for a partition with a surface element and on a fixed mounting rail verfahrbaren carriage disclosed, of which at least one with a Drive is provided for moving the wall element. In one embodiment, the drive is a pressure medium member with an electrically operated pump, which also serves to actuate upper and lower sealing strips.

CA 948 982 relates to wall elements of a mobile wall, the upper and lower sealing elements are clamped and relaxed by means of a hand-operated hydraulic pump.

Based on this prior art, the object of the present invention is to provide a bracing system for a mobile wall element, which has a low weight with high flexibility, small footprint and high reliability and a corresponding mobile wall element and mobile wall system with low weight, which is easy to produce ,

This object is achieved by a bracing system for a mobile wall element which is horizontally and / or vertically braceable in a mobile wall system by means of at least one movable extension pressure shoe, the bracing system having a hydraulic device by means of which the extension pressure shoe is movable for bracing the mobile wall element, wherein the hydraulic device is a hydraulic Pump and at least one connected to the hydraulic pump hydraulic cylinder for moving an Ausfahrdruckschuhs, which is further developed in that the hydraulic cylinder is associated with a restoring device, which is designed as a return spring or as a pneumatic return piston, which is arranged in particular in the hydraulic cylinder.

The invention is based on the idea that the use of hydraulic devices in bracing systems for mobile wall elements has the advantage that a large and heavy metal rod is partially or completely eliminated and replaced by hydraulic devices. These are smaller building than the conventional tensioning mechanics and therefore have a lower weight.

Since hydraulic lines can be laid arbitrarily within a mobile wall element, for example along the frame, large areas of the mobile wall element become free for wicket doors or windows. The gained space in the mobile wall element can also be used for sound or heat insulation improving deposits.

Especially with telescopic elements that are braced not only vertically but also horizontally, mechanical bracing systems are complex and costly and weight-intensive, since the force exerted on the tensioning forces must be deflected several times. In a hydraulic tensioning system, the arrangement of a lightweight hydraulic cylinder on a side Ausfahrdruckschuh the mobile wall element suffices.

The hydraulic device comprises a hydraulic pump and at least one hydraulic cylinder connected to the hydraulic pump for moving an extension pressure shoe. This represents the simplest possibility of a tensioning system with a hydraulic device.

The hydraulic pump includes a reservoir of hydraulic fluid or hydraulic oil which, upon actuation of the hydraulic pump by a hydraulic line to the hydraulic Cylinder is pumped and this moves. As a result of the movement, the hydraulic cylinder moves the extension pressure shoe outwards. So the mobile wall element is braced.

The hydraulic cylinder is associated with a restoring device according to the invention. In this case, the restoring device is designed as a return spring or as a pneumatic return piston, which is arranged in particular in the hydraulic cylinder. Both variants ensure that when the hydraulic pump relaxes the extension pressure shoe does not remain in its extended position, but is retracted again. As a result, the tension of the mobile wall element between the ceiling and floor or in the mobile wall system is reliably solved.

In particular, for telescopic elements, it is advantageous if at least two hydraulic cylinders are provided for at least two Ausfahrdruckschuhe. Of the Ausfahrdruckschuhen at least one is arranged on one side of the mobile wall element and another at the top or bottom of the mobile wall element. The latter Ausfahrdruckschuh serves to brace the mobile wall element between the ceiling and floor, the former for lateral tension in mobile wall systems against adjacent mobile wall elements or a side wall.

In order to prevent internal stresses in the mobile wall system, there is an advantageous embodiment of the bracing system with at least two hydraulic cylinders is that the contact pressures for at least two Ausfahrdruckschuhe are separately adjustable. In particular advantageously, the at least two hydraulic cylinders can be controlled separately. The vertical tension of the telescopic wall element is made after the horizontal tension or vice versa. In this way, internal stresses in the mobile wall are compensated even before the final tensioning of the telescopic element.

Depending on the distance between the hydraulic pump and the hydraulic cylinder, a hydraulic connection of the hydraulic pump and the hydraulic cylinder is designed as a hydraulic pressure line or as a hydraulic pressure pipe. For small distances, a lightweight and flexible hydraulic pressure line is sufficient, while at long distances a hydraulic pressure line leads to an undesirable pressure drop and is advantageously replaced by a hydraulic pressure tube.

To drive the hydraulic pump of the tensioning system, it is advantageously possible to provide a transmission that can be connected to a crank, in particular bevel gearboxes. Since hardly any mechanical losses occur in the hydraulic tensioning system, the mobile wall system can easily be tense even by weak and inexperienced operators by hand.

It is advantageously provided an electric motor for driving the hydraulic pump, in particular in addition a mechanical drive of the hydraulic pump is provided.

In order to prevent too great a pressure occurring in the hydraulic tensioning system and damage to pressure lines, for example, a hydraulic pressure compensation cylinder is advantageously connected to the hydraulic pump. This ensures that when a too high, in particular specifiable, pressure occurs, the hydraulic fluid is deflected into the pressure compensation cylinder. In this case, the other hydraulic components, in particular the hydraulic lines and the hydraulic cylinders, are not overloaded.

The object underlying the invention is also achieved by a mobile wall element with a bracing system described above. The low weight of the tensioning system according to the invention leads to lightweight mobile wall elements. These are easy and fast to manufacture due to the flexibility of the bracing system. To avoid repetition, reference is made to the above.

Likewise, the object underlying the invention is achieved by the use of a tensioning system according to the invention described above in a mobile wall element.

Finally, the object is also achieved by a mobile wall system having one or more mobile wall elements with an inventive bracing system described above.

In the following figures, identical or similar elements or corresponding parts are provided with the same reference numerals, so that a corresponding renewed idea is dispensed with.

In Fig. 1 a space with a mobile wall system or a mobile partition wall is shown in perspective. In front of the mobile wall, the floor 50, side walls 51, 52 and the ceiling 53 of the partitioned space are shown. Through gaps in the mobile wall, the rear wall 54 can be seen.

The mobile wall consists of mobile wall elements 61, 62, 63, 64, 65, which are suspended on guide rails 55. The elements 61 and 62 are already braced in their predetermined positions in the mobile wall between the floor 50 and ceiling 53. The mobile wall member 63 with crank 11 is in a position just before Connection with the mobile wall element 62. By means of the crank 11, the mobile wall element 63 is braced vertically between the floor 50 and the ceiling 53.

The mobile wall elements 64 and 65 are located on the right side in a parking position, which occupies little space. They are not clamped in the parking position between the ceiling 53 and floor 50, their Ausfahrdruckschuhe are sunk in the mobile wall elements 64, 65.

Fig. 2 shows a schematic representation of an embodiment of a mobile wall element according to the invention 1. The mobile wall element 1 is a telescopic element having a main wall body 2 with a frame 3 and an upper Ausfahrdruckschuh 4, a lower Ausfahrdruckschuh 5 and a lateral Ausfahrdruckschuh 6.

By the upper Ausfahrdruckschuh 4 two guide slides 7, 8 are performed, which are fixed to the frame 3 and in a guide rail, as in Fig. 1 be hung.

The hydraulic tensioning system comprises a hydraulic pump 9, which is driven by means of a crank 11 via a bevel gear 10. The hydraulic pump 9 has a manifold with a plurality of outlets, from which branch hydraulic pressure lines and pressure pipes 12 to 12 "". About the pressure lines and pressure pipes, the hydraulic fluid, which is shown hatched in the hydraulic pump 9 and the other hydraulic devices, distributed to hydraulic cylinders 13, 16, 19, 21 and a hydraulic pressure compensating cylinder 23.

To clarify the principle of the device are the individual Parts of the hydraulic tension system, in particular the hydraulic pressure lines and pressure pipes 12 to 12 "" not in perspective but shown schematically.

In the mobile wall element 1, the contact pressures for the side extension pressure shoe 6 and the upper and lower Ausfahrdruckschuhe 4, 5 are set differently, so that inner tension in the mobile wall system are compensated during the tensioning.

The hydraulic cylinders 13, 16 are held in the extension pressure shoes 4 and 5 by means of guide holders 14, 17. In addition, they have return springs 15, 18 which ensure that when the hydraulic cylinders 13, 16 are relieved, the extension pressure shoes 4, 5 are retracted and the tension between the ceiling and the floor is released.

The hydraulic cylinders 19, 21 are firmly anchored with connecting elements 20 and 22 in the lateral Ausfahrdruckschuh 6. As a restoring element, the hydraulic cylinders 19, 21 prestressed pneumatic piston, which are arranged in the hydraulic cylinders 19, 21.

The outer shells of the hydraulic cylinders 13, 16, 19, 21 are connected to the frame 3 of the main wall body 2 of the mobile wall element 1, so that the Ausfahrdruckschuhe 4, 5, 6 are each extended against the frame 3.

Of the hydraulic lines 12 to 12 "", the hydraulic lines 12, 12 'are formed as hydraulic pipes, since a large distance between the hydraulic pump 9 and the hydraulic cylinders 13, 19 must be bridged, which is flexible Hydraulic lines can lead to an undesirable pressure drop.

In Fig. 3 a further embodiment of a mobile wall element 31 according to the invention is shown. There are upper and lower Ausfahrdruckschuhe 34, 35 are provided to brace the mobile wall element 31 between the ceiling and floor.

As in the embodiment according to Fig. 2 Also in this embodiment, the tensioning system comprises a hydraulic pump 9, which in this case is operated by an electric drive 36, and hydraulic cylinders 15, 37, 38, of which the hydraulic cylinder 15 is equipped with a return spring 16, while the hydraulic cylinders 37, 38 have pneumatic return piston. Furthermore, a pressure compensation cylinder 23 is provided. The hydraulic cylinders 15, 37, 38 and the hydraulic pressure compensating cylinder 23 are connected to the hydraulic pump 9 via a pressure line 39 and pressure pipes 39 'to 39 "'.

In the lower part of the mobile wall element 31, the hydraulic components are respectively arranged at the edge, so that space for a wicket door 40 is. The wicket 40 has a locking system 41, hinges 42, 43 and an inner strut 44 (shown in phantom).

In the upper part of the mobile wall element 31 is enough space to provide a hydraulic pressure cylinder 15 for the upper Ausfahrdruckschuh 34 approximately centrally. In order to exert on the lower Ausfahrdruckschuh 35 a uniform pressure while leaving room for the wicket door 40, left and right two hydraulic cylinders 37, 38 are necessary.

The representation of the arrangement of the hydraulic pressure line 39 and pressure pipes is to be understood schematically. The pressure pipes and pressure pipes 39 'to 39 "' are laid inside the mobile wall member 31 but outside the frame of the wicket door 40.

As an alternative to a wicket door, the space in the mobile wall element obtained by the bracing system according to the invention offers the possibility of obstructing a window or other large-area elements. The interior of the mobile wall element can also be lined over a large area with sound and / or heat-insulating material.

The bracing system according to the invention and the mobile wall elements according to the invention offer the advantage that the bracing system can be quickly manufactured or installed in the manner of "plug and play", thus ensuring rapid production. The bracing system can also be installed in existing mobile wall elements.

By means of the various hydraulic cylinders, the contact pressures for the telescopic extension pressure shoes and for the other extension pressure shoes are specifically separately adjustable and controllable.

The hydraulic tensioning system weighs significantly less than a mechanical tensioning system with the necessary stable metal rods. As a result, the mobile wall elements according to the invention as a whole are lighter than known mobile wall elements with purely mechanical tension systems and therefore easier to handle.

The saving of mechanical parts reduces the Friction in the system, so that lower actuating forces are necessary. This increases the operability of the mobile wall system according to the invention, even for weak and inexperienced operators.

Finally, the mobile wall elements according to the invention have a great variability and a large variety, so that now more diverse and flexible spatial distribution concepts can be implemented as before.
