【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 3 is a sectional view of the partition device 11 of the first embodiment. The partition device 11 is constructed by adhering rubber sheets 16 and 17 that generate sliding friction to the upper surface and the lower surface of a wall panel including the end portion 12, the air spring 13 and the panel body 18, respectively. The end portion 12 is formed into an iron rail shape having a substantially U-shaped cross section, and the lower end is bent at 45 degrees. The end portion 12 is arranged with its concave portion facing downward, and a V-shaped groove 18a is provided in the upper portion of the panel body 18, and a rubber tube air spring 13 having a substantially inverted triangular outer shape is stably stored. To be done. In this way, the panel body 18 is fitted into the recess of the end portion 12, and the air spring 13 expanded by air is sandwiched between the end portion 12 and the panel body 18. Elongated rubber sheets 16 and 17 each having a predetermined thickness are attached to the upper surface 14 of the end portion 12 and the lower surface 15 of the panel body 18 with an adhesive. Therefore, since no guide rails or guide fittings are used, the ceiling 19 and the floor surface 20 are not damaged, and the partition device 11 can be easily attached and detached.

Next, the operation of the partition device 11 will be described. As shown in FIG. 4, the air spring 13 has the same structure as an air tube in a wheel of a bicycle or the like and is formed in a linear shape, and has an air port 21 made of metal at one end thereof. By supplying air from the air port 21 by a manual air pump (not shown), the air spring 13 is filled with air and the air spring 13 expands. Then, the end portion 12 is vertically urged toward the ceiling 19 by the air pressure of the air spring 13, and the panel body 18 is urged vertically downward toward the floor 20. In this way, the end portion 12 and the air spring 13 act as a movable portion, the rubber sheet 16 is sandwiched between the upper surface 14 and the ceiling 19 and compressed as shown in FIG. 3, and similarly the rubber sheet 17 is sandwiched between the lower surface 15 and the floor 20. Be compressed. Therefore, the elastic force generated by the expansion of the air spring 13 causes the rubber sheets 16 and 17 to be pressed from above and below to increase the sliding friction resistance of the rubber sheets 16 and 17, so that the partitioning device 11 is moved to the ceiling 19. It is erected between the floor and the floor 20 and securely fixed. Therefore, even if a horizontal force is applied to the panel body 18, the lateral displacement of the panel body 18 can be steadily prevented.

When it is desired to remove the partition device 11 or to move it to another place, if the screw of the air port 21 is removed, air is released from the air spring 13 and the end 12 descends. Since there is a gap between the ceiling 19 and the rubber sheet 16, the partition device 11 can be moved very easily, and there is an advantage that no scratches remain after removing the partition device 11.

Next, a second embodiment will be described. FIG. 5 is a cross-sectional view of the partition device 21 of the second embodiment, in which a mechanical vertical drive unit 23 is provided in place of the air spring 13 of the first embodiment to mechanically move the end 22 up and down. . The vertical drive unit 23 is fixed to the inner portion of the panel body 28 by a bolt or the like, and includes a worm gear 23a, a worm shaft 23c having a worm 23b meshing with the worm gear 23a, and a housing 23d. When the hexagon wrench 23e is inserted into the shaft hole of the worm 23a through the lateral hole of the panel body 28 and rotated around the horizontal axis, the rotation of the worm gear 23a around the horizontal axis is caused by the worm 23b. It is converted into the vertical movement of 23c. Therefore, the disk 23f at the upper end of the worm shaft 23c moves the end 22 up and down. In addition, a horizontal maintaining device (not shown) is provided for vertically moving the end portion 22 while keeping the end portion horizontal. Then, the above-mentioned vertical drive unit 23 is fixed to the panel body 28, and the voids of the rear panel body 28 are filled with polyurethane. Polyurethane sheets 26 and 27, which are formed to have predetermined slender thicknesses and generate sliding friction, are attached to the upper surface 24 of the end portion 22 and the lower surface 25 of the panel body 28 with an adhesive.

Next, the operation of the partition device 21 will be described. By inserting the hexagon wrench 23e from the outside of the panel body 28 and rotating the worm gear 23a, the worm shaft 23c and the end portion 22 move up and down integrally. Then, when the polyurethane sheet 26 reaches the ceiling, the polyurethane sheet 26 is pressed by being sandwiched between the upper surface 24 and the ceiling 29, and similarly, the polyurethane sheet 27 is pressed by the lower surface 25 and the floor 20. Thus, the polyurethane sheets 26, 27 are pressed from above and below by the mechanical pressing force generated by the driving of the vertical drive unit 23, and the sliding friction resistance of the polyurethane sheets 26, 27 is increased, so that the partitioning device 21 is It is erected between the ceiling 19 and the floor 20 and securely fixed. Therefore, even if a horizontal force is applied to the panel body 28, the lateral displacement of the panel body 28 can be steadily prevented.

Naturally, various embodiments can be taken without departing from the scope of the present invention. For example, in place of the air spring 13, any structure may be used such as a coil spring or the like that generates elastic force. Further, the rubber sheets 16 and 17 and the polyurethane sheets 26 and 27 generate sliding friction. Other materials may be used as long as they are materials. Further, the rubber sheets 16 and 17 and the like are not limited to being fixed by an adhesive, but may be fixed by various means such as welding. Further, not only the wall panel but also the pillar has a similar structure, and it is naturally possible to use a plurality of pillars and wall panels connected to each other.

[0013]

[Effect of device]

 Since the present invention is composed of a movable part capable of expanding and contracting a wall panel and a sheet provided on the upper and lower surfaces of the wall panel to cause sliding friction, it does not damage the ceiling or floor at all, and the partition device can be easily attached and removed. Therefore, the working time can be shortened. The partitioning device is erected between the ceiling and the floor and is securely fixed by applying a pressing force from above and below to the sheet that causes sliding friction by the extension force of the movable part to increase the sliding friction resistance. Therefore, even if a force is applied to the partition device in the horizontal direction, it is possible to steadily prevent the partition device from rolling sideways. Further, since the mechanism is a simple air spring type, the cost is suppressed and the structure is simple.
