Abstract

Thermal and acoustic insulated panel (1) suspended from the wall by ball bearing discs (2), slide on a rail (3) and are slidably fitted under beam (4) which has a number of pressure cylinders (5) of which piston (6) is driven by a pump ((7).The pump is controlled by a switch (8) to push the rail with the ball bearing discs downwards and again when required to lift. Tops and bottoms of panels are covered with flexible rubber strips (9) providing an efficient seal effect. Panels can also be moved laterally using pressure cylinder (5) and piston (6).

Description

The present invention relates to a device for Ab Limitation of premises by means of vertical convertible plates walls, which are light in weight and have a great acoustic and ther Mix have insulating value.

Such panel walls, which are used in particular in rooms, whose surface has to be changed to fit the needs, are already known and they are increasingly in conference halls, hotels, offices, canteens, etc.

In the known Plattenwandkonstruktionen shows as adjustable walls itself as a disadvantage that to move always exhausting and time-consuming Work has to be done in order to enlarge or distort a room smaller, with insulation against draft, heat loss and disturbing Noise usually suffers significant loss because the panels are not accurate connect to each other and on the ceiling and bottom side no perfect Conclusion can be achieved.

In the Brit. Patent 1,017,319 describes vertically suspended wall parts, which can be moved by hand along rails.

The panels can be used as wall and door parts, and they preferably consist of parallel smooth plates, between which a Insulating mass of foam material was attached, which expanded Contains cells.

The filling of the panels is made of plastic foam (polyester or Polyurethane), foam rubber, gypsum or fiber material, with smooth surfaces. To set up, remove or store these plates, they must slightly raised and rotated 90 °, whereupon they touch each other can be pushed and stored for example in a corner can.

The manual operation for such panel walls takes place by means of a rod  or a key instead.

To adjust the panels of a wall more conveniently and conveniently can and fix them in such a way that they no longer feel like it can rotate and move, the device of the invention proposed, which is characterized in that pressing Cylinders are the hydraulically or pneumatically actuated piston rods include, at the top and, if necessary, also at the sides Rails are mounted, in such a way that the pressure in single or total exerted on the top and side edges until the plates fully connect side by side and vertically.

The present invention will become more apparent from the accompanying figures explained. Therein are the parts of the relevant device shown schematically in cross section.

In these figures, corresponding parts are given the same reference numerals specified.

Fig. 1 shows a wall panel consisting of plates, whose plates ( 1 ) on ball-bearing rotating and running disks ( 2 ) within a rail system ( 3 ) on the ceiling of the room and reversibly hung on the side of the space, and wherein the rail system ( 3 ) is located below a ceiling beam ( 4 ) on which pressure cylinders ( 5 ) are mounted, each of which actuates a hydraulically or pneumatically operated piston ( 6 ) driven by an electrically controlled pump which is switched on and off by a switch.

The plates are provided along their top and bottom with semi-circular flexible rubber sealing profiles ( 9 ), so that the sliding bare wall forms a completely insulating conclusion when the plates ( 1 ) by means of the cylinder ( 5 ) are pressed to the floor. It can be mounted one above the other several ball-bearing rotating and running wheels, whereby the directional possibilities are increased when moving.

Fig. 2 shows a vertical cross section through a fiction, modern device with a wall panel (1), the ball bearing turning and running wheel (2) in the rail (3) mounted on the beam (4), so that the pressure cylinder (5) by means of the piston ( 6 ), driven by the pump ( 7 ), controlled by the switch ( 8 ), the wall plate, for example a door plate ( 1 ), can press down, the rubber seals ( 9 ) at the top and bottom Finish the edge.

Fig. 3 shows in an alternative embodiment in cross-section a plate ( 1 ) on which from laterally in a wall or a support column introduced piston ( 6 ) which are guided in the pressure cylinder ( 5 ), also a lateral displacement can be performed , so that the narrow side edges of the plate ( 1 ) are pushed together sealingly. Fig. 4 shows how a plurality of ball-bearing rotating and running wheels can operate on the other to adjust all possible angles when moving can.

With the help of the device according to the invention, the switching, Ver push and shovel without much effort even in very large Premises, such. As offices, stages, sports halls, museums, Off and meeting rooms, very convenient and always changeable be executed.

When converting the room walls in such buildings and halls is significant Saves time, because by the pressure cylinder a significant faster and easier fixation at the desired location is possible as with conversion with manual operation.

Physical properties of the wall panels are in the following table summarized.

Claims (3)

1. Adjustable wall, consisting of individual rectangular wall panels of thermally and acoustically insulating wall material, which are attached to discs with outstanding rotatable balls, so that they are rotatable and laterally displaceable, characterized in that the wall parts ( 1 ) of the wall on spherical discs ( 2 ), each on a rail ( 3 ) can be pushed and rotated, which is mounted under a beam ( 4 ), wherein the bar ( 4 ) at intervals with vertical pressure cylinders ( 5 ) is provided, the piston ( 6 ) of a Pump ( 7 ) are controlled by a switch ( 8 ), so that the rail ( 3 ) with the spherical discs ( 2 ) can be pushed down and lifted upwards, the upper and lower edges of the wall parts with flexible Rubber strips ( 9 ) are covered, so that a complete foreclosure is guaranteed. 2. Wall according to claim 1, characterized in that the wall parts ( 1 ) can also be adjusted laterally by means of pressure cylinders which are mounted horizontally on the side wall or a support of the room. 3. Suspension of wall parts for walls according to claim 1 and 2, characterized characterized in that it consists of several successive rotatable ball-bearing discs whose balls partially from the Slice protrude.
