It is screwed in such a way that it comes into contact with the small diameter side end face. The large-diameter end face of the small bevel gear 27 is in contact with the upper surface of the bearing metal 24. A lock nut 31 is screwed onto the lower surface of the bearing metal 24 of the feed screw shaft 28, and the lock nut 31 presses the small bevel gear 27 from the lower surface to press the small bevel gear 27 against the head 30. It has become. Therefore, the small bevel gear 27, the feed screw shaft 28, and the lock nut 31 rotate integrally with the bearing metal 24. Lock nut 31
The collar 32 is fitted on the lower surface side of the
Is configured to prevent the connecting block 34 from colliding with the intermediate bracket 23 when the feed nut 33 described later is raised.

A feed nut 3 is provided at an intermediate portion of the feed screw shaft 28.
The connection block 34 is fixed to the feed nut 33 so as to move integrally therewith. The connection block 34 is formed in a rectangular parallelepiped box shape having an open lower surface wall and a side wall on the base 21 side, and a feed screw shaft 28 is inserted into an insertion hole 35 formed in the upper surface wall of the connection block 34. The connection block 34 is covered with the feed nut 33 and the end bracket 25, and a locking pin 36 is provided at a lower end of the connection block 34 between a pair of opposed side walls. The above-described wire 17 is locked to the locking pin 36.

At the upper end of the main surface of the base 21 on the side where the feed screw shaft 28 and the like are arranged, a bearing hole 37 is formed so as to penetrate in the thickness direction. The large bevel gear 38 meshing with the shaft is arranged so that its axis is orthogonal to the feed screw shaft 28, and is rotatably supported. That is, a journal portion 39 and a thrust portion 40 are formed on the large bevel gear 38, and the journal portion 39
Is inserted into the bearing hole 37, and the thrust portion 40 is
Is in contact with the edge of the opening. A thrust plate 41 is in contact with the end face of the journal portion 39 of the large bevel gear 38 and is fixed by a screw 42. The thrust plate 41 faces the thrust portion 40 and receives the large bevel gear 38 in a thrust bearing. ing.

A rotary operation shaft 43 projects from the center line of the thrust plate 41, and the rotary operation shaft 43 is inserted through an insertion hole 38 a formed on the center line of the large bevel gear 38. The end of the rotary operation shaft 43 protruding from the large bevel gear 38 is formed in the shape of a quadrangular prism having a square cross section, and the rotary operation shaft 43 is configured to be rotated when the handle 44 is fitted. ing. As shown in FIG. 3, a handle insertion port 45 is provided at a position facing the rotation operation shaft 43 on the mating surface 11 c of the right frame member 11 b, and the handle 44 is inserted into the handle insertion port 45. , Is fitted to the rotation operation shaft 43.

Next, the operation will be described. When the moving wall 10 is moved or the like, as shown in FIG. 3, the seal 13 is in a state of being immersed in the storage section 12 of the wall 11. That is, since the feed nut 33 screwed to the feed screw shaft 28 is located at the upper limit shown in FIG. 1, the wire 17 is drawn into the right frame member 11b. In this state, since the wire 17 is pulled by the spring 14, the feed nut 33 is strongly pressed against the feed screw shaft 28 to exert a large frictional force.
Is in a state where natural rotation from the feed nut 33 side is prevented. Therefore, the feed screw shaft 28 and the feed nut 33 can maintain the state in which the wire 17 is drawn.

As described above, since the wire 17 is maintained in the state of being pulled in by the feed screw shaft 28 and the feed nut 33, the right and left pulleys 19 and 20 are supported by the wire 17 from below. Maintains the state of being floated from the floor surface 4 as shown in FIG. 3, so that the moving wall 10 can move smoothly without being obstructed by the seal body 13.

Next, 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 44 is inserted from the handle insertion opening 45 to rotate the rotating operation shaft 43. And the large bevel gear 38 is rotated against the pulling force of the spring 14 in a direction in which the feed nut 33 is lowered (hereinafter, referred to as a positive direction). When the large bevel gear 38 is rotated in the forward direction, the small bevel gear 2
7, the feed screw shaft 28 is rotated in the direction of lowering the feed nut 33, so that the feed nut 33 is prevented from rotating by the end bracket 25 and the connection block 34.
Moves forward on the feed screw shaft 28 and is lowered as shown in FIG.

When the feed nut 33 is lowered, the wire 17 linked to the feed nut 33 by the connecting block 34 and the locking pin 36 is brought out, and is supported by the wire 17 via the left and right pulleys 19 and 20. The seal body 13 protrudes from the wall body 11 by the elastic force of the spring 14 and comes into contact with the floor surface 4 to seal the gap between the lower end surface of the wall body 11 and the floor surface 4. Since the gap between the moving wall 10 and the floor surface 4 is blindfolded by the seal by the seal body 13, the appearance of the moving wall 10 is enhanced, and the gap between the moving wall 10 and the floor surface 4 is sealed. The soundproofing effect is enhanced.

Thereafter, when the moving wall 10 is moved, for example, when the moving partition is moved, the handle 44 is inserted from the handle insertion opening 45 and attached to the rotary operation shaft 43, and the large bevel gear 38 is fed. The nut 33 is rotated in a direction to raise the nut 33 (hereinafter, referred to as a reverse direction). When the large bevel gear 38 is rotated in the opposite direction, the small bevel gear 2
7, the feed screw shaft 28 is rotated in a direction to raise the feed nut 33, so that the feed nut 33 is prevented from rotating by the end bracket 25 and the connection block 34.
Retreats on the feed screw shaft 28 and is raised as shown in FIG.

When the feed nut 33 rises to the upper limit on the feed screw shaft 28 and the rotation of the large bevel gear 38 by the operation of the handle 44 is stopped, the feed nut 33 is linked with the connecting block 34 and the locking pin 36. The wire 17 is pulled into the right frame member 11b. In this state, the feed nut 33 is strongly pressed against the feed screw shaft 28 by pulling the wire 17 by the spring 14, so that the feed screw shaft 28 is prevented from spontaneous rotation from the feed nut 33 side. State. Therefore, the feed screw shaft 28 and the feed nut 33
Can maintain the state in which the wire 17 is pulled.

As described above, according to the present embodiment, since the wire for making the sealing member protrude and retract is linked to the feed nut which moves linearly, the wire only reciprocates by the linear motion, and Can be prevented from being repeatedly subjected to bending stress. And
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, compared to the case of using a chain, rod, link mechanism, etc. as a means for extending and retracting the seal body,
While the weight of the entire moving wall can be reduced,
The structure of the operating device can be greatly simplified.

Since the immersion state of the seal body can be reliably maintained by the frictional force of the feed nut screwed into the feed screw shaft, the protrusion of the seal body during the movement of the moving wall can be reliably prevented without a lock mechanism. can do. However, this does not prevent the provision of a lock (rotation prevention) mechanism for the feed screw shaft, the large bevel gear, and the like.

By disposing the feed screw shaft, feed nut, small bevel gear, large bevel gear, rotary operation shaft, and the like of the operating device on the mating surface of the wall, the handle insertion port can be opened on the mating surface. Because it is possible, it is possible to prevent the handle insertion port from being seen in front of the moving wall,
As a result, it is possible to prevent the appearance performance of the moving wall from deteriorating.

Further, by disposing the feed screw shaft, the feed nut, the small bevel gear, the large bevel gear, the rotary operation shaft, and the like of the operating device of the operating device on the mating surface of the wall, the wall can be disassembled. Since maintenance and inspection can be performed by removing the sealing member and the like on the mating surface, maintenance performance can be improved.

Since the gap between the lower surface of the wall and the floor can be sealed by the seal, the appearance 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.

The one shown in FIG. 5 has a pair of folding link devices 51, 51 interposed on the left and right, and both folding link devices 51, 51 are linked by tie rods 52. Note that the support structure of the seal body is not limited to the embodiments shown in FIGS. 3, 4, and 5, and can be appropriately changed.

FIGS. 6A and 6B show a moving wall according to another embodiment of the present invention. FIG. 6A is a front sectional view, and FIG. 6B is a partially cut side view. 7A and 7B show a main part of the moving wall, wherein FIG. 7A is a side view, and FIG. 7B is a cross-sectional view taken along line bb of FIG.

The second embodiment differs from the first embodiment in that an upper seal 13A for sealing a gap between the upper end surface of the wall 11 and the rail 2 is formed at the upper end of the wall 11. The upper feed screw shaft 28A for operating the upper seal body 13A is connected to the large bevel gear 38 via the small bevel gear 27A. That is, as shown in FIG. 6, the upper feed screw shaft 28 is provided on the upper seal body 13A.
A is connected to a feed nut 33A which is screwed forward and backward by an upper wire 17A, and the upper feed screw shaft 28A is connected to the lower feed screw shaft 28 on the base 21 as shown in FIG. A large bevel gear 3 which is arranged on the opposite side of the small bevel gear 27 and meshes with the small bevel gear 27 of the lower feed screw shaft 28.
8 through a small bevel gear 27A.

According to the second embodiment, the upper seal 13
Since A can also seal the gap between the upper end surface of the wall 11 and the rail 2, the aesthetic appearance and soundproofing effect of the moving wall can be further enhanced. Moreover, since the upper feed screw shaft 28A is linked to the large bevel gear 38 to which the lower feed screw shaft 28 is linked, the lower seal body 13 and the upper seal body 13A can be raised and lowered by the same operation. it can.

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the scope of the present invention.

For example, the rotation operating means for rotating the feed screw shaft is not limited to be constituted by a bevel gear mechanism and a handle, but may be constituted by a motor with a reduction gear.
