Description

[Detailed description of the invention] This invention is a sealing device for a movable wall such as a sliding wall or a movable wall for the purpose of airtightly shielding the gap between the upper end and the ceiling and the gap between the lower end and the floor. It is related to the device.

Conventionally, due to the structure of movable walls such as sliding walls or moving walls, gaps were likely to be formed between the upper end and the ceiling and between the lower end and the floor, so the sound insulation effect of the movable wall was There were some unexpected flaws.

However, in this invention, an operating rod is installed horizontally within the wall of the movable wall, and lifting rods are installed vertically on the upper and lower sides of the operating rod. An extrusion rod is vertically installed at the outer end of the rod with a compression spring in between so that it can be raised and lowered, and the extrusion rod is connected to a sealing member that is installed at the upper and lower ends of the wall body so that it can be raised and lowered. Since it can be pressed against the ceiling or floor via a compression spring,
They succeeded in preventing the formation of gaps, which could not be avoided in the past, and creating a movable wall with extremely high sound insulation effects equivalent to permanent walls.

That is, to explain this invention with reference to an embodiment, a wall body 4 is constructed by arranging panels 3, 3 in which a sound absorbing material 2 such as honeycomb or foam material is sandwiched between surface materials 1, 1 and facing each other at a predetermined distance. In a sliding wall in which the wall 4 is connected and suspended via a runner 7 to a hanging rod 8 movably installed on a guide rail 6 installed inside the ceiling 5, the central part of the internal space of the wall 4 is The operating rod 9 is slidably installed horizontally on the
Two pairs of lifting rods 10, 10 are vertically installed in parallel to each other above and below the operating rod 9. Each of the lifting rods 10 is fitted into a guide tube 11 vertically installed in the wall 4,
It is inserted into the plate 12 fixed to the middle part of the guide tube 11, and has lifting blocks 13, 13a at the upper and lower ends.
A return spring 14 is fitted between the lifting block 13 and the plate 12. Further, one end of a link piece 15 is connected to the lifting block 13 so as to be rotatable by a small angle, and the other end of the link piece 15 is connected to the operating rod 9.
It is connected to a block 16 that is fitted and fixed to the block 16 so that it can rotate by a small angle, and the horizontal movement of the operating rod 9 is controlled by the lifting rod 1.
0 vertical motion. On the other hand, an extrusion rod 17 is installed opposite to the outside of the end of the elevating rod 10, and a compression spring 18 is interposed between the elevating block 13b fixed to the base end of the extruding rod 17 and the elevating block 13a. , the tip side of the extrusion rod 17 is a plate 12a fixed to the guide tube 11.
It penetrates through and protrudes out of the guide cylinder.

At the upper and lower edges of the panel 3 constituting the wall body 4, there are shaped frames 19 each having a cross-section shaped member facing each other.
A mold material 21 having a sealing material fitting groove 20 formed on the upper surface thereof is slidably inserted into the inside of the shaped frame 19. The strip 22 is attached to form a sealing member.

Connecting rods 23 are fixed to the tips of the extrusion rods 17 in the thickness direction of the wall 4, and both ends of the connecting rods 23 are penetrated into one side wall of the mold member 21 of the sealing member to connect the connecting rods 23. The extrusion rod 17 and the mold material 21 are connected through the extrusion rod 17. In the figure, 24 is the floor. In order to allow a large number of wall bodies 4 of the same shape to be arranged in parallel, a recessed groove 25 is formed on each side end surface, and a part of the sealing material 26 having a U-shaped cross section attached to one side is adjacent to the wall body 4. It is fitted into the recessed groove 25 of the wall body to provide airtightness of the adjacent portion. However, the recessed groove 2
A through hole 28 for operating the operating rod 9 is bored in the middle part of the mold material 27 fixed to form the handle 5. This through hole 28 is an elongated hole through which a locking piece 30 fixed perpendicularly to a rod body 29 rotatably screwed to one end of the operating rod 9 can pass.
When it is pushed into the wall 4 and rotated 90 degrees, the locking piece 30 locks on the edge of the hole and cannot be returned to its original position.

In the above embodiment, after the wall body 4 is moved to a predetermined position along the guide rail, the rod body 2
9 into the wall 4 to slide the operating rod 9 in the horizontal direction (in the direction of arrow 31 in FIG. to rise or fall. As the elevating rod 10 moves up and down, the extruding rod 17 is pushed out of the wall 4 via the compression spring 18, and eventually the sealing members installed at the upper and lower ends of the wall 4 are connected to the ceiling 5.
Or move it in the direction of the floor 24 and remove the sealing protrusion 22.
The upper and lower outer ends of the wall body 4 can be airtightly shielded by the airtight member by bringing the wall body 4 into contact with the ceiling 5 or the floor 24 in a pressed state. The airtight members are moved by extrusion rods 17 pushed out via compression springs 18 and brought into contact with the ceiling 5 or the floor 24, so that the airtightness between the surface of the ceiling 5 or the floor 24 and the wall is maintained. Even when the members are not in a parallel relationship, the sealing protrusion 22 can be reliably brought into contact with the sealing protrusion 22, and it is possible to eliminate the possibility of creating a gap on the contact surface that would impair the sound insulation effect.

In the embodiment, there are two pairs of elevating rods 10 and extrusion rods 17 which are raised and lowered by the operation rod 9, but the number may be one pair or three or more pairs, and may be determined as appropriate in consideration of the width of the wall body 4.

That is, according to this invention, the airtight members provided at the upper and lower edges of the movable wall are raised and lowered via extrusion rods supported by compression springs inside the wall, thereby ensuring that the airtight members are in contact with the ceiling or floor. I made it possible for you to contact me,
This has the effect of providing a movable wall with a high sound insulation effect.
Since the operating rod for raising and lowering the airtight member and the lifting rod for pushing out the extrusion rod are connected via a diagonal link piece, the mechanism can be simplified and the operation of the operating rod can be performed easily and quickly. There is. In particular, when extruding the extrusion rod, the extrusion rod is urged in the extrusion direction by a compression spring, so that the airtight material can be securely brought into contact with the ceiling and the floor, and a high sound insulation effect can be obtained.

On the other hand, since the operating rod is provided with a locking piece at one end to be connected to and removed from the side end surface of the movable wall, a high sound insulation effect can be reliably maintained with a simple operation.
