A large lateral force is applied to the pin 20, and this force acts as a vertical force that strongly separates the upper and lower links 18,19.

As a result, the toggle link 17 is
2 is strongly pressed down, and the casters 15 attached thereto are strongly pressed against the floor surface 4. The panel unit 1 is pushed up by the reaction force at this time, and both casters 15 project from the lower end of the panel unit 1 and come into contact with the floor, so that they can move.

As a result, the entire weight of the panel unit 1 is applied to both the casters 15, so that no load is applied to the guide rails 3 and a function of merely guiding the guide rollers 8 and preventing the panel unit 1 from tipping over. have.

On the other hand, when the panel unit 1 is moved to a predetermined position and then touches the floor surface 4, the operation lever 24 on the rear side of the operation lever 23 is depressed with a foot in the state shown in FIG. Is rotated backward and downward as shown in FIG. Then, the lower link 19 rotates clockwise, contrary to the above, the upper link 18 rotates counterclockwise, and the toggle link 17 bends in a square shape. Thereby, the movable plate 12 moves upward together with the casters 15, and
The whole of the panel unit 1 that has been raised up to that time relatively lowers and comes into contact with the floor, and the casters 15 are separated from the floor surface 4 and housed in the base member 11.

When the panel unit 1 comes into contact with the floor, the gap between the upper end of the panel unit 1 and the guide rail 3 becomes large, but this gap is closed by the expansion of the sound absorbing material 10 described above, so that there is a problem in sound insulation. Will not be.

FIG. 5 shows a second embodiment of the present invention.

In this embodiment, the elevating means of the panel unit 1 comprises a fillet 26 housed in the base member 11 so as to be vertically movable, and an elevating mechanism 27 provided in the panel unit 1. .

The casters 15, 15 are directly mounted on the lower surfaces of the left and right ends of the upper surface plate 11a of the base member 11 so as to slightly protrude from the lower end of the panel unit 1.

The fillet 26 has an upward U-shape capable of accommodating the casters 15, and an elastic member 28 such as rubber is attached to the bottom plate 26a.

The elevating mechanism 27 includes two frames 1a,
Horizontal screw rod 29 supported at both ends by the inner wall of 1a
A swing arm 31 having an upper end screwed to the screw rod 29 and a lower end pivotally attached to a bracket 30 of the upper surface plate 11a of the base member 11, and a slightly downwardly inclined short arm having a front end pivotally attached to the upper end. Dimensional first link 32 and rear end of frame 1
