Then, with the cover 41 removed, the wire 17 is inserted from below through the insertion opening 23a formed in the side wall of the lower bracket 23, and is locked by the lower guide pin 25 of the rack 26. ing. Seal body 13 is wall body 1
In the state where it is projected from 1 and maintains the seal,
As shown in FIG. 1, the rack 26 is located at the lower limit and the wire 17 is in an extended state.

For example, when the moving wall 10 is moved,
The seal 13 is immersed in the storage section 12 of the wall 11. That is, the rack 26 of the operating device 16 is positioned at the upper limit shown in FIG.
7 is retracted. In this state,
The engaging portion 36 of the main body 35 of the ratchet 34 is engaged with a part of the tooth row 27 of the rack 26, and the main body 35 is in a state where the engaging claw 37b is engaged with the stopper pin 37a to prevent reverse rotation. Therefore, the rack 26 is in a state where the linear movement downward is prevented. Therefore, the rack 26 is in a state where the state where the wire 17 is drawn is maintained.

As described above, the wire 17 is connected to the rack 26
Since the wire 17 is maintained in the retracted state,
The seal body 13 that supports the left and right pulleys 19 and 20 from below is floated from the floor surface 4 as shown in FIG. Therefore, moving wall 1
0 can move smoothly without being obstructed by the seal body 13.

When the sealing body 13 is projected from the wall body 11 after the moving wall 10 is arranged at a predetermined place, the handle 46 is inserted into the ratchet side handle insertion opening 40.
Is inserted, the main body 35 of the ratchet 34 is rotated counterclockwise in FIG. 2A against the pulling force of the spring 38. When the main body 35 of the ratchet 34 is normally rotated in the counterclockwise direction, the engaging portion 36
The rack 26, which is constantly urged through the wire 17 by the pulling force of the spring 14 on the wall 11 side to release the meshing with the tooth row 27, moves downward with the guide hole 24 and the guide pin 25 as guides. Make a linear motion.

When the rack 26 linearly moves downward, the wire 17 is unreeled, so that the seal 13 supported by the wire 17 via the left and right pulleys 19 and 20 is resiliently moved by the spring 14 to the wall. 11 and abuts against the floor surface 4 to contact the lower end surface of the wall body 11 with the floor surface 4.
Is sealed. This seal 1
3 seals the gap between the moving wall 10 and the floor 4 so that the appearance of the moving wall 10 is enhanced, and the gap between the moving wall 10 and the floor 4 is sealed, so that the soundproofing effect is obtained. Enhanced.

Thereafter, when the moving wall 10 is moved, such as when the moving partition is moved, the handle 46 is inserted into the pinion-side handle insertion port 32,
The pinion 29 is rotated counterclockwise in FIG. 2A against the pulling force of the spring 14 on the wall 11 side. When the pinion 29 is rotated counterclockwise,
Since the teeth 27 of the rack 26 are fed by the teeth 30 of the pinion 29, the rack 26 linearly moves upward. At this time, the engaging portion 36 of the ratchet 34 is sent counterclockwise by the tooth row 27 of the rack 26, so that the main body 35 of the ratchet 34 releases the engagement between the stopper pin 37a and the engaging claw 37b. Since the rack 26 rotates in the rolling direction, the rack 26 can linearly move upward without being hindered by the ratchet 34.

The rack 26 is raised to the upper limit and the handle 4
When the rotation of the pinion 29 is stopped by the operation 6, the main body 35 of the ratchet 34 is pulled by the spring 38 and is rotated clockwise in FIG. 26 teeth 2
7 and the engaging claw 37b is
7a. In this state, the wires 17 are connected to the rack 26.
When the pulling force of the spring 14 on the wall 11 side is applied to the rack 26, the rack 26 is in a state where the linear movement downward is prevented by the ratchet 34.

As shown in FIG. 2B, when the rack 26 reaches the upper limit and is prevented from moving downward, the wire 17 is in a retracted state. The seal body 13 supported by the wire 17 via 20 is immersed in the storage section 12 of the wall body 11 and is separated from the floor surface 4. That is, the wall 11
Is floating from the floor 4, so that the moving wall 10 is movable with respect to the floor 4.

As described above, according to the present embodiment, since the wire for allowing the sealing member to protrude and retract is locked to the rack that moves linearly, the wire only reciprocates by the linear motion, Can be prevented from being repeatedly subjected to bending stress. Then, by preventing the bending stress from acting repeatedly on the wire, it is possible to realize the adoption of the wire as a means for causing the sealing body to protrude and retract. By using a wire, the weight of the entire moving wall can be reduced and the structure of the operating device can be significantly reduced as compared with the case where a chain, a rod, a link mechanism, etc. are used as a means for extending and retracting the seal body Can be simplified.

Further, the immersion state of the seal can be reliably maintained by the ratchet meshed with the teeth of the rack, so that the protrusion of the seal during the movement of the moving wall can be reliably prevented.

Furthermore, by disposing the rack, pinion, ratchet, etc. of the operating device on the mating surface of the wall, the pinion handle insertion port and the ratchet handle insertion port can be opened on the mating surface. These openings can be prevented from being viewed in front of the moving wall, and as a result, the appearance performance of the moving wall can be prevented from deteriorating.

By mounting the cover for covering the rack, pinion, ratchet, etc. of the operating device on the base detachably, the maintenance can be performed by removing the cover without disassembling the wall body. Can be enhanced.

Since the gap between the lower surface of the wall and the floor can be sealed by the seal, the appearance performance and soundproof performance of the moving wall can be improved. In addition, by arranging the operating device for causing the seal to protrude and retract on the frame member of the wall, it is possible to avoid a decrease in the sound insulation effect due to arranging the operating device in the center of the wall.
