Description

DETAILED DESCRIPTION OF THE INVENTION The purpose of the present invention is to prevent the deflection of an airtight device for improving sound insulation when movable walls are arranged. The present invention relates to a balancer for a movable wall connected by a balancer device such that the deflection of each airtight member cancels out the deflection of the other airtight member, thereby balancing the deflection forces of both airtight members and reducing deflection. It is something.

A movable wall, which is the basis of the present invention, will be explained with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a suspension wheel, and the suspension wheel 1 is constructed by rotatably supporting wheels 5 on both front and rear sides of an elongated suspension wheel main body 4.

In the figure, 38°39 is a rotation direction plate.

Hanging bolts 2 are hung downward from the front and rear of the central part of the hanging wheel body 4, respectively, and the hanging bolts 2 are lined up in the traveling direction of the hanging wheel 1.

Reference numeral 3 in the figure indicates a movable wall, which moves in a direction perpendicular to the surface of the movable wall 3. Hanging wheels 1 are installed at both left and right ends of the upper surface of the movable wall 3, respectively, so that the hanging wheel 1 can move forward. The suspension wheel 1 is arranged so that the direction is perpendicular to the surface of the moving wall 3.
A plurality of hanging bolts 2 hanging from the movable wall 3 are respectively attached to the front side and the rear side of the upper surface of the movable wall 3.

The figure shows an example in which the movable wall 3 is suspended by two hanging wheels 1, and two hanging bolts 2 are hung from each hanging wheel 1, but the invention is not limited to this. Alternatively, the movable wall 3 may be suspended by three or more hanging wheels 1, and three or more hanging bolts 2 may be suspended from the hanging wheels 1.

In the figure, two hanging bolts 2 are hung from each of the two hanging wheels 1, but when attaching the hanging bolts 2 to the upper surface of the movable wall 3, only one of the four hanging bolts 2 in total is attached. Three hanging bolts 2 are rotatably fixed to a movable wall 3, and the other three hanging bolts 2 are provided with idler wheels 6 at the bottom that rotate in a direction perpendicular to the traveling direction of the hanging wheel body 4. An idler wheel 6 is placed in a hanging frame 7 which is opened elongately in the left-right direction on the upper surface of the movable wall 3, and the movable wall 3 is suspended so that it can move in the left-right direction with respect to the hanging bolts 2.

In the figure, 12 is an elongated opening of the hanging frame 7.

In the figure, 8 is a hanger rail, 9 is a wheel running surface, 1
0 is a surface for preventing wheel lifting, and 11 is a rotation direction plate guide rail surface.

Thus, the wheels 5 run on the wheel running surface 9, and as the hanging wheel 1 moves forward, the movable wall 3 is moved to perform a predetermined movement.

Here, the three movable walls can be tilted by α as shown in FIG. It is possible to run the wall 3 at an incline as shown in Fig. 4 without applying unreasonable force, and it is possible to run even with unequal moving forces on the left and right, and it is also possible to partition the wall 3 by inclining it. This will allow you to create a variety of room partitions.

When such a movable wall is installed, the movable airtight member that maintains the airtightness between the wall and the adjacent movable wall and increases the loud noise is explained using a diagram. 13 in Figure 4 is An airtight member provided on the upper surface, lower surface, and left and right end surfaces of the movable wall 3, and an elastic material 15 such as rubber on the upper part of the frame 14.
It is attached and formed.

The movable wall 3 has built-in vertical movable grooves on both left and right sides as shown in FIG.

In Fig. 4, 16 is a worm having a square hole 11 for inserting the handle, 18 is a worm wheel, 19 is a pinion, and 2
0 is a rack, and a shaft 21 is integrally fixed to the rack 20.

The upper end of the shaft is pivotally supported at an eccentric position on one side of a rotating disk 22 which is pivotally supported on the movable wall 3, and an upper shaft 23 is pivotally supported at an eccentric position on the other side of the rotating disk 22. be.

In the figure, 24 is a rotary joint which is rotatable about a shaft 37, and 25 is a tongue buckle for adjusting dimensions.

In the figure, reference numeral 26 denotes an end shaft having one end screwed into a turnbuckle 25, and a frame 14 positioned vertically at the other end is fixed.

In the figure, reference numeral 27 denotes a spring that constantly presses the frames 14 located above and below outward.

A wire 28 is attached to the shaft 21, and the wire 28 is connected to the frame 1 located on the left and right sides via a pulley 29.
The frame 14, which is fixed to the frame 4 and located on the left and right sides of the frame 14, is constantly pressed outward by a spring 30.

When the handle insertion hole 17 is inserted from the outside of the movable wall 3 into the handle 31 and rotated, the rotation is transmitted to the worm 16, worm wheel 18, and pinion 19 in this order, and the rack 20 moves downward. The downward movement causes the shaft 21 to move downward, and by rotating the rotating disk 22, the upper shaft 23 moves upward.

As the shaft 21 moves downward and the upper shaft 23 moves upward in this way, the upper and lower frames 14 move upward and downward, respectively.
The elastic material 15 attached to the hanger rail 8 comes into pressure contact with the hanger rail 8, and the elastic material 15 attached to the frame 14 located below comes into pressure contact with the floor.

In this case, since the frame 14 is pushed outward by the spring 27 at an appropriate pitch, the pressure contact is made even more airtight.

On the other hand, when the shaft 21 moves downward, the attachment part of the wire 28 to the shaft 21 moves downward, which loosens the wire 28 and causes the frames 14 located on the left and right sides to protrude outward due to the spring force of the spring 30. A girder elastic member 15 is installed at 14 and presses against the wall or the adjacent movable wall 3.

Further, the upper and lower frames 14 are retracted against the barb 271 that turns the handle 31 in the opposite direction, and the wire 28 is pulled, and the left and right frames 14 are retracted against the spring 30.

By the way, the airtight member 13ν having the frame 14 and the elastic material 15 disposed above and below as described above has the elastic material 15.
Since it is heavier than rubber, etc. and is long, measuring 3 to 5 meters, it flexes significantly, resulting in poor appearance as a partition wall and poor airtightness, making it extremely inconvenient as an airtight device for a movable wall. be.

- The present invention prevents the deflection of the moving wall airtight device as shown in the paper, and uses a balancer device to prevent the frame 14 from bowing.

Next, embodiments embodying the present invention will be described with reference to the accompanying drawings following the fifth figure.

FIG. 5 is a schematic front view showing the arrangement of upper and lower airtight members and a balancer device according to an embodiment of the present invention, and FIG. 6 is a perspective view of the balancer device.

In these figures, the balancer device 32 is arranged at the center inside the movable wall 3, and the balancer device 32 is arranged at the center inside the movable wall 3, and the balancer device 32 is mounted on a disk 3 that is pivotally supported on the movable wall 3.
The upper azusa 34 is pivotally supported at an eccentric position at one end of the disk 33.
The upper frame 35 is pivotally supported at the eccentric position of the other end, and the upper frame 34,
A rotation joint 24 and a turnbuckle 25 are attached to the upper frame 35, respectively.
The frames 14 disposed above and below are connected to form a balancer device 32.

This balancer device 32 operates as follows.

In other words, since the frame 14 disposed at the bottom tries to bow downward, a force is generated that tries to rotate the disk 33 in the direction of arrow A in FIG. The disc 33 tries to bend downward in an arch shape.
A force is generated to rotate the frame 14 in the direction of the arrow in FIG. It happens.

Therefore, when the vertical movement mechanism A is operated to move the frame 14 up and down, the disc 33 moves in conjunction with the vertical movement of the frame 14.
rotates, and the upper azusa 35 and the upper azusa 34 move up and down, but the upper and lower frames 14 are kept at the center by constantly balancing the downward deflection of the upper frame 14 and the lower frame 14. This will prevent it from bending.

At least one balancer device is provided on each movable wall, and if the width K of the movable wall is wide, a plurality of balancer devices may be provided to further reduce the amount of deflection.

As described above, the present invention has the upper and lower airtight members attached to the upper and lower parts of the movable wall that can be moved guided by banger rails installed on the ceiling so as to be freely extended, and each of the above airtight members Since this is a movable wall balancer that is connected to one or more balancer devices that cancel out the deflection of each other's airtight members to reduce the deflection of the airtight members, it is possible to move the upper and lower airtight members by any desired distance. Even if the balancer device of the present invention is used to prevent deflection, it does not cause any change in the deflection prevention function even if the spacing is changed. The amount of deflection is reduced to less than half that of one without a prevention device, which is an extremely important effect for movable walls that partition rooms beautifully and with great noise.
