Next, the operation will be described.

When the moving wall 10 is moved, the lower seal body 26 and the upper seal body 37 are in a state of being sunk into the lower storage portion 22 and the upper storage portion 31 of the wall body 11, respectively. That is, as shown in FIG.
Since the left nut 75 and the right nut 76 screwed to the feed screw shaft 72 are located at the inner limits of the left guide hole 83 and the right guide hole 84, the left first link bar 85 and the right first link bar 86 are provided. The lower seal body 26 supported by the left side first link bar 85 and the right side first link bar 86 is drawn into the lower side storage portion 22 because the is closed. This state also applies to the upper seal body 37.

As described above, since the lower seal body 26 and the upper seal body 37 are respectively immersed in the lower housing portion 22 and the upper housing portion 31 of the wall body 11, the moving wall 10 is lowered. The trolley 3 can move smoothly without being obstructed by the side seal body 26 and the upper seal body 37.

Next, when the lower seal body 26 and the upper seal body 37 are projected from the lower storage portion 22 and the upper storage portion 31 of the wall body 11 after the moving wall 10 is arranged at a predetermined position. Is attached to the rotary operation shaft 97 by inserting the handle into the handle insertion opening 98, and the driving-side bevel gear 99
Is rotated in a direction in which the lower seal body 26 and the upper seal body 37 are projected.

The rotation of the driving-side bevel gear 99 is performed by the feed screw via the driven-side bevel gear 100 of the connecting shaft 93, the connecting shaft 93, the driving-side bevel gear 91 of the connecting shaft 93, and the driven-side bevel gear 90 of the feed screw shaft 72. Since it is transmitted to the shaft 72, the left nut 75 and the right nut 76, which are screwed forward and backward with the feed screw shaft 72, are respectively advanced outward. When the left nut 75 and the right nut 76 advance, respectively, the left first link bar 8
5 and the right side first link bar 86 are erected by the action of the left side second link bar 87 and the right side second link bar 88, respectively.
It is projected downward from 2 by the elastic force of the left side springs 81, 81A and the right side springs 82, 82A.

When the projected lower seal member 26 abuts the rug 8 on the floor surface 7 (see FIG. 1), the left first link bar 8
5 and the first link bar 86 on the right side are in a state of being prevented from standing up, and therefore are left behind by the forward movement of the left nut 75 and the right nut 76 and left slider 77 and right slider 7
8 is in a state where the movement with respect to the feed screw shaft 72 is stopped. In this state, the elastic force of the left spring 81 and the right spring 82 acts on the left slider 77 and the right slider 78, so that the lower seal body 26
Is in a state of being elastically pressed against the floor surface 7, so that the lower seal body 26 seals the gap between the lower end surface of the wall body 11 and the floor surface 7 very effectively. Therefore, the lower seal body 26 surely conceals the gap between the moving wall 10 and the floor surface 7 to enhance the appearance of the moving wall 10,
The soundproof effect is enhanced by elastically sealing the gap between the moving wall 10 and the floor surface 7.

The above-described projecting operation and state of the lower seal body 26 are the same for the upper seal body 37 shown in FIG.

Thereafter, when moving the moving wall 10 as in the case of moving the moving partition, the handle is inserted from the handle insertion opening 98 and attached to the rotary operation shaft 97, and the rotary operation shaft 97 is different from the above. The springs 81, 81A, 82, 82A are rotated in the opposite direction against the elastic force of each spring.

The left nut 75 and the right nut 76, which are screwed forward and backward with the feed screw shaft 72, are respectively retracted inward. When the left nut 75 and the right nut 76 retract, respectively, the left slider 77 and the right slider 78, which receive the elastic force of the left spring 81 and the right spring 82, also retract, so that one end is connected to the left slider 77 and the right slider 78. The left first link bar 85 and the right first link bar 86 are laid down by the action of the left second link bar 87 and the right second link bar 88. By this operation, the lower seal body 26 is drawn into the lower storage portion 22.

A left nut 75 and a right nut 76, into which the lower seal member 26 is inserted into the lower housing portion 22 and screwed into the feed screw shaft 72, are arranged in the left guide hole 83 and the right guide hole 8.
When the feed screw shaft 72 is positioned at the inner limit of 4, the rotation of the feed screw shaft 72 is blocked, and the operation of the handwheel handle device 95 is stopped.

The above-mentioned operation and state of the lower seal member 26 for immersing are the same for the upper seal member 37 shown in FIG.

According to the above embodiment, the following effects can be obtained.

1) By transmitting the rotational operation force of the handwheel handle device to the feed screw shaft via the connecting shaft to make the seal body appear and disappear, it is possible to surely and swiftly operate even a large seal body. it can.

2) By omitting the wire in the operating device for retracting the seal body, it is possible to avoid problems regarding repeated bending stress on the wire and elongation of the wire, and to wire the wire inside the wall body. Work can be abolished.

3) By disposing the feed screw shaft and nut, the connecting shaft, the handwheel handle device and the bevel gear transmission device of the operating device for retracting the seal body on the frame members on the upper and lower sides and the left and right sides, a summoning board and the like. Since the maintenance work can be performed without disassembling the wall body by removing the, the efficiency of the maintenance work of the operating device can be improved. Further, by disposing the operating device entirely inside the frame member of the wall body, it is possible to avoid a reduction in the sound insulation effect due to disposing the operating device in the central portion of the wall body.

4) By inserting the connecting shaft of the operating device into the tunnel portion formed in the right (left) frame member and closing the tunnel portion with the cover, the sound absorbing material filled in the groove of the right frame member becomes the connecting shaft. Since it is possible to prevent entanglement, it is possible to ensure rotation of the connecting shaft,
In addition, the sound insulation performance of the right frame member on which the connecting shaft is arranged can be maintained.

5) Since the end portion of the connecting shaft of the operating device is supported by the steady rest bracket, the centering can be secured and the runout can be prevented even with a long connecting shaft, so that the umbrellas arranged at both ends are prevented. It is possible to ensure meshing and rotation transmission of the gear transmission.

6) Since the weight of the wall can be set light by using aluminum as a constituent material for the upper, lower, left and right frame members, face plates, etc., a rail for suspending and moving the moving wall. The restrictions on mechanical strength of trolleys, laying strength of rails, etc. can be relaxed,
The cost of the moving wall system as a whole can be reduced. Further, when the weight is set to the same, the soundproofing performance can be improved.

7) Since the upper frame member is supported from below by a steel suspension member and the rod of the trolley is fixed to the suspension member, the weight of the wall can be dispersed to the steel suspension member. The use of aluminum material for the upper frame member can be realized.

8) By laying the panel cushioning members on the lower end and the upper end of the wall body, it is possible to prevent the face plate of the wall body and the frame member from being damaged due to collision between the wall bodies. It is possible to realize the use of an aluminum material for the face plate, the frame member and the like.

Needless to say, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

For example, the rotary operation means for rotating the connecting shaft is not limited to the manual handle device and the bevel gear transmission device, but may be a motor with a reduction gear or the like.

It is not limited that the protruding and retracting seal bodies are arranged above and below the wall body to seal both the upper surface and the lower surface of the wall body, but only one of the upper and lower sides of the wall body is sealed. May be.
