Description

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

Mobile wall systems Also known as partition systems, are used for variable subdivision of spaces. Known mobile wall systems have a usually mounted in the ceiling guide rail and possibly a guide rail attached to the floor and flat mobile wall elements from a resting position where they take up little space, moved out and put together to a complete partition can and vice versa.

The individual mobile wall elements are realized by means of movable elements, so-called Ausfahrdruckschuhe, braced between the ceiling and floor. The Ausfahrdruckschuhe are fully or partially in the non-actuated state sunk in the mobile wall element. In the extended state, they protrude over the mobile wall element out and are pressed against ceiling or floor or ceiling rail or bottom rail. In the context of the invention, the ceiling rail as part of the Ceiling and accordingly the floor rail as an ingredient of the soil.

at known tension systems are the Ausfahrdruckschuhe with metal rods connected by means of a scissor mechanism or apart be moved towards each other, the Ausfahrdruckschuhe off or retract. By extending the or the Ausfahrdruckschuhe is braced the mobile wall element between the ceiling and floor.

Mobile wall systems optionally comprise further mobile wall elements, so-called telescopic elements, the except a vertical tension between ceiling and floor another one horizontal tension by means of another, laterally arranged, Allow extension pressure shoe. This requires a complicated mechanism with more metal rods. With telescopic elements mobile partitions from several mobile wall elements are sealed locked.

at These telescopic elements, the bracing systems have a scissors mechanism up, over which is exerted on all Ausfahrdruckschuhe the pressure. The telescope elements can be clamped vertically and horizontally at the same time. That can lead to tension and tilting in the mobile wall element.

The Mobile wall elements of the prior art have next to or several extension pressure shoes and the linkage of the tensioning mechanism a housing with a frame and two facing walls on. In this case is the tensioning mechanics from the outside not visible.

For a safe Tensioning the mobile wall elements, it is necessary that the Ausfahrdruckschuhe along its extent a uniform contact pressure on the Ceiling, the floor and possibly the side exercise. Around to keep the number and weight of the metal bars low, are the Metal bars of the tensioning mechanism inside the mobile wall element centrally mounted, so that the metal bars with a cross shape a scissors mechanism as a crossing point in the center of the mobile wall element form. This consumes much space in the surface of the mobile wall element. So it is hardly possible breakthroughs for wicket doors or Windows in conventional Mobile wall elements with cruciform Provide tensioning mechanism.

About the Tensioning mechanics must put a strong pressure on the extension pressure shoes be exercised. This means that the metal bars must be very stable. conventional Tensioning mechanics are therefore difficult.

at Tensioning mechanisms occur relatively high friction losses. To overcome friction, it is known, in addition to crank systems and electric Provide drives. These systems also exhibit in some cases mechanical emergency functions.

A wall element for insertion between floor and ceiling in a building is off AT 413 412 B known. This is a lower and an upper terminating element is provided, which is executed federbelas tet, so that the wall element with spring-loaded contact pressure between the floor and ceiling of a building can be fixed. The wall element further consists of inner, vertically extending support rails and both sides applied cladding panels. For mounting, a spring element can be brought by means of an adjusting device from an inactive, relaxed position into a clamping position.

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

These Task is by a bracing system for a in a mobile wall system by means of at least one movable Ausfahrdruckschuhs horizontal and / or vertically tensionable mobile wall element solved, the is further developed in that the bracing system is a hydraulic Device, by means of which the Ausfahrdruckschuh for bracing of the mobile wall element is movable.

The Invention is based on the idea that the use of hydraulic Devices in bracing systems for mobile wall elements the advantage that has a big one and heavy metal linkage partially or completely deleted and replaced by hydraulic devices. These are smaller building as the conventional one Tensioning mechanism and therefore have a lower weight on.

There hydraulic lines as desired within a mobile wall element can be relocated For example, along the frame, large areas of the mobile wall element become for wicket doors or Window free. The space gained in the mobile wall element can also be used for sound or heat insulation improving Deposits are used.

Especially with telescopic elements that are not only vertical but also horizontal are strained, mechanical tension systems are complex and Cost and weight intensive, as the on the tensioning mechanics exerted Forces several times have to be diverted. In a hydraulic Verspannungssy system, the arrangement of a lightweight enough Hydraulic cylinder on a side Ausfahrdruckschuh the mobile wall element.

advantageously, For example, the hydraulic device comprises a hydraulic pump and at least one connected to the hydraulic pump hydraulic Cylinder for moving an extension pressure shoe. This is the simplest possibility a bracing system with a hydraulic device.

The Hydraulic pump includes a reservoir of hydraulic fluid or hydraulic oil, that when pressed the hydraulic pump through a hydraulic line to the hydraulic Cylinder is pumped and this moves. Moved by the movement the hydraulic cylinder pushes the extension pressure shoe outwards. So the mobile wall element is braced.

advantageously, the hydraulic cylinder is assigned a restoring device. Here is the reset device preferred as a return spring or as a pneumatic return piston, which is arranged in particular in the hydraulic cylinder is formed. Both variants ensure that when relaxing the hydraulic Pump does not remain in its extended position, but is recovered. As a result, the tension of the Mobile wall element between ceiling and floor or solved reliably in the mobile wall system.

Especially for telescopic elements it is advantageous if at least two hydraulic cylinders for at least two Ausfahrdruckschuhe are provided. From the extension pressure shoes at least one is disposed on one side of the mobile wall element and another at the top or bottom of the mobile wall element. The latter extension pressure shoe serves to tension the mobile wall element between ceiling and floor, the former for lateral tension in Mobile wall systems against adjacent mobile wall elements or a Side wall.

Around To prevent internal tension in the mobile wall system, there is a advantageous embodiment of the bracing system with at least two Hydraulic cylinders in that the contact pressures for at least two extension pressure shoes are separately adjustable. In particular advantageously the at least two hydraulic cylinders are separately controllable. In this case, the vertical strain of the telescopic wall element after the horizontal tension made or vice versa. To this Way, internal tension in the mobile wall already before the final one Balancing the telescopic element compensated.

ever according to the distance between hydraulic pump and hydraulic Cylinder is a hydraulic connection of the hydraulic pump and the hydraulic cylinder as a hydraulic pressure line or designed as a hydraulic pressure tube. For small distances one is enough lightweight and flexible hydraulic pressure line, while at long distances one 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 also be easily operated by weak and inexperienced operators tense by hand.

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

Around To prevent too high a pressure in the hydraulic tension system occurs and about pressure lines are damaged, is advantageous a hydraulic pressure compensation cylinder with the hydraulic pump connected. This ensures that when an excessively high, in particular specifiable, pressure occurs the hydraulic fluid is deflected into the pressure balance cylinder. In this case will be the remaining hydraulic components, in particular the hydraulic lines and the hydraulic cylinders, not overloaded.

The The object underlying the invention is also achieved by a mobile wall element with a bracing system described above. The low weight of the tension system according to the invention leads to light Mobile wall elements. These are due to the flexibility of the bracing system easy and fast to produce. To avoid repetition is referred to the above.

As well the problem underlying the invention is solved by the use of a tensioning system according to the invention described above in a mobile wall element.

Finally will the task also solved by a mobile wall system having one or more mobile wall elements with a tensioning system according to the invention described above.
