When generated, it is in close contact with the magnetic force, and when the magnetic force is lost (offset) comprises a wobble bar 43 is lifted apart from the building floor 2 by the restoring force of the spring (42).

As shown in FIG. 8, the wandering bar 43 is generally shaped like a wedge, which is retractably fitted into a generally wedge-shaped storage bar 44 attached to a lower end of the wall panel 20. A lower end portion is fixedly attached to the wedge bar 43, and an upper portion of the support post 45 penetrates through the storage bar 44, and a compression coil installed between the upper end of the support post 45 and the upper surface of the storage bar 44. When the magnetic force is not applied to the electromagnet 41 by the spring 42, the wandering bar 43 is fitted inside the storage bar 44 and is lifted apart from the bottom 2, but the magnetic electromagnet 41 When the magnetic force is mad, the magnetic force is pulled downward while overcoming the force of the compression coil spring 42 to be in close contact with the electromagnet 41 embedded in the bottom (2).

The electromagnet 41 has a structure in which magnetic force is normally applied to the outside and a magnetic force acting externally when power is applied, that is, an electromagnet in which magnetic poles are converted by a current flowing through a coil, together with a general permanent magnet. It is installed so that the current flows only when the adsorption magnetic force is on / off, and the maintenance of the adsorption magnetic force is made by stimulus arrangement between permanent magnets. When the wall panel 20 is closed, the magnetic force acts to the outside and the wall panel (20) Since the lower part of the wedge bar 43 is caught, the wall panel 20 is kept in a closed state stably. When the wall panel 20 is to be opened, the adsorption magnetic force is lost when power is applied. The wobble bar 43 attached to the lower end of the wall panel 20 is lifted apart from the building floor 2 so that the wall panel 20 can be rotated and slided. will be.

Since the supply of power for the control of the electromagnet 41 is made only in preparation for the opening and closing operation, it is possible to prevent waste of excessive electric energy.

When the plurality of wall panels 20a, 20b, 20c, and 20d reach a fully open state as shown in FIGS. 5 and 7, the plurality of wall panels 20a, 20b, 20c, and 20d are applied to the driving unit 30 by a conventional limit switch, etc., not shown. When the power is cut off, further excessive slide movement is prevented, and the plurality of fully open wall panels 20a, 20b, 20c, and 20d overlap each other in close contact with each other and are accommodated in a minimum space. The space can be integrated and used widely.

On the other hand, in the case of closing the wall panel which was opened in the opposite direction to the above, all the wall panels 20a to 20d overlapped with the rail 10 are moved in parallel with the rail 10 while the wall panels 20a to 20d overlap the rail 10. Direction is rotated at right angles to the original position and the original angle, and in such a state, when the power applied to the electromagnet 41 is cut off, the magnetic force that has been canceled is generated to the outside and thus each wall panel 20a, 20b, 20c, 20d By pulling out the haunting bar 43 installed at the lower end of the wall panel is to maintain a stable state.

As described above, the present invention provides a variable wall system capable of automatically opening and closing a non-bearing wall for dividing a space between a room and a room, a room and a living room, such as when the living room is to be used widely or when the number of rooms is increased. The internal structure of the living space can be changed freely according to the change of patterns or the change of members due to the growth or marriage of members, thereby increasing the utilization of space, and the structural change is a simple operation of the control box or the remote controller. It is to be made quickly and easily, and the rotation and slide movement of the individual wall panel is made by the drive unit using one motor, so the system itself is very simple and can be manufactured and installed at low cost. The rails are not exposed on the floor, The high functional aspects and the actual use of the complete system has the beneficial effects that can cater for all practical aspects should not have any trouble.
