Description

TECHNICAL FIELD The present invention relates to a moving partitioning device used when partitioning a floor of a hotel, an office, or the like as needed.

[Prior Art] In this type of moving partition device, a ceiling rail having a continuous opening in a bottom wall is fixed to a ceiling of a building, and a plurality of traveling bodies can travel in the ceiling rail. With the placement
Suspension rods are attached to the intermediate portions of these traveling bodies, and the lower ends of the suspension rods are made to pass through the openings and hang down below the ceiling rail. The movable walls are suspended and supported by the pair of suspension rods, and the movable walls can be moved along the ceiling rail. When partitioning the floor with such moving walls, these moving walls are arranged in a line along the ceiling rail, and both ends in the width direction are brought into close contact with each other. Further, in order to close the gap between the upper edge of the moving wall and the ceiling surface and the gap between the lower edge of the moving wall and the floor surface, which are required during movement, The upper and lower contact members are projected so as to be in close contact with the corresponding ceiling surface and floor surface, respectively.

In this way, the upper and lower close contact members are made to project and retract by the close contact member drive mechanism in which the moving wall is installed. A conventional close contact member drive mechanism has an operation shaft having two types of screw parts that are mutually reverse screws, a pair of nuts screwed into the screw parts of the operation shaft, and a link member having a diamond shape. The left and right pivot points are pivotally connected to the nuts 4
It is provided with a point link and an up-and-down shaft connecting the upper and lower pivot points of the four-point link and the upper and lower contact members, respectively, and the operation shaft is supported by the frame of the moving wall. .

[Problems to be Solved by the Invention] With such a configuration, by rotating the operation shaft via a detachable handle or the like, a nut screwed into both screw portions of the operation shaft is provided. When the four-point links are moved in the direction toward each other, the left and right pivot points of the four-point link approach each other, and the upper and lower pivot points perform a separating operation. As a result, above,
The lower elevating shaft moves in a separating direction, the upper contact member is pressed against the ceiling surface, and the lower contact member is brought into close contact with the floor surface. An elastic expansion / contraction part is provided in the middle of each elevating shaft so that each elevating shaft can be elastically contracted when the upper and lower contact members are pressed against the ceiling surface and the floor surface. There is. However, with this alone, if there is a relatively large difference between the gap from the upper edge of the moving wall to the ceiling surface and the gap from the lower edge of the moving wall to the floor surface, the upper contact is close. The pressing force on the ceiling surface of the member,
There may be a large difference between the pressing force of the lower contact member to the floor surface, which adversely affects the sound insulation performance and the light shielding performance.

Further, with such a configuration, there are problems that the structure inside the moving wall becomes complicated due to the large number of parts, the manufacturing and adjustment are troublesome, and it is difficult to reduce the weight of the moving wall.

The present invention aims to solve such problems.

[Means for Solving the Problems] The present invention adopts the following configurations in order to achieve the above objects.

That is, the moving partition device according to the present invention, the ceiling rail, the traveling body, the suspension rod, the moving wall, the upper and lower close contact member, the upper and lower lifting shaft, a fluid pressure type expansion and contraction mechanism,
Fluid pressure control means, wherein the ceiling rail has a continuous opening on the lower surface, and the traveling body is disposed so as to be able to travel in the ceiling rail. The suspension rod is held by the traveling body, and the lower end side of the suspension rod is hung downward from the opening of the ceiling rail, and the moving wall is mounted on the ceiling rail via the suspension rod and the traveling body. Is suspended and supported so as to be movable, and the upper and lower contact members are arranged at upper and lower edge portions of the moving wall so as to project and retract toward a ceiling surface and a floor surface, The both elevating shafts are arranged so that the base ends thereof face each other so as to be able to ascend and descend within the moving wall, and each of the tip ends holds the upper and lower contact members. It is configured to use elastic fluid as a working fluid and expand and contract according to the rise and fall of fluid pressure. It is interposed between the descending shaft,
The fluid pressure control means is configured to change the fluid pressure supplied to the expansion / contraction mechanism, and is arranged so as not to interfere with the expansion / contraction and lifting operation of the expansion / contraction mechanism. .

In order to reduce the number of parts, the expansion and contraction mechanism is urged by a spring for urging the shafts in a direction toward each other and an internal working fluid pressure interposed between the elevating shafts to move the elevating shafts. It is preferable to include an output bellows container that is pressed in the separating direction.

In order to reliably prevent the leakage of the working fluid, in addition to the expansion mechanism including the above-mentioned output bellows container, the fluid pressure control means is provided with a fluid pressure control bellows container,
A deformable pipe line for communicating the inside of the fluid pressure control bellows container with the inside of the output bellows container;
It is preferable that the fluid pressure control bellows container can be manually or electrically operated to be reduced.

If you want to reduce the force to operate the fluid pressure control bellows container without using a special mechanical booster mechanism,
It is preferable that the fluid pressure control bellows container has an effective diameter smaller than that of the output bellows container.

[Operation] With such a configuration, the expansion / contraction mechanism can be expanded / contracted by changing the pressure of the working fluid introduced into the expansion / contraction mechanism by the fluid pressure control means. Then, when the expansion / contraction mechanism is contracted, the upper and lower lifting shafts are pulled in a direction toward each other, and the upper and lower contact members are held in the retracted position. On the other hand, when the elastic member is extended, the upper elevating shaft is pressed upward, the lower elevating shaft is pressed downward, and the upper contact member is projected upward and pressed against the ceiling surface,
The lower contact member projects downward and is brought into close contact with the floor surface. At this time, since the expansion and contraction mechanism can freely move up and down, the upper contact member and the lower contact member are pressed against the ceiling surface and the floor surface with a relatively uniform force. In particular, since a compressive fluid such as air is used as the working fluid of the expansion / contraction mechanism, the upper and lower contact members can be attached to the ceiling surface and the floor surface without providing an elastic expansion / contraction portion in the middle of the lifting shaft. Can be properly elastically contacted.

At a position that does not hinder the expansion and contraction of the expansion / contraction mechanism 8 and the vertical movement.
A fluid pressure control means 9 is provided. The fluid pressure control means 9 is
A fluid pressure control bellows container 91 having an effective diameter smaller than that of the output bellows container 82, and a deformable conduit 82 for communicating the inside of the fluid pressure control bellows container 91 with the inside of the output bellows container 82. The fluid pressure control bellows container 91 can be reduced by an electric actuator 93. More specifically, a guide tube 95 having left and right end plates 94 is installed between the edge member 51 and the intermediate column member 52e, and the fluid pressure control bellows container 91 is provided in the guide tube 95. Is accommodated so that it can be expanded and contracted. The conduit 92 connected to one end of the fluid pressure control bellows container 91 is made of a bendable material,

A slit 95a parallel to the axis is formed on the lower surface of the guide cylinder 95. The electric actuator 93 includes a bearing 93a at one end and one end plate 9
A screw rod 93c which is supported by 4 and the other end of which is supported by the other end plate 94 through a gear box 93b, and a motor 93d which is connected to the screw rod 93c through a gear in the gear box 93b. Nut member 93e screwed onto the screw rod 93c
And a pressing arm 93f protruding from the nut member 93e and slidably passing the slit 95a through the slit 95a and inserted into the guide cylinder 95. The distal end of the pressing arm 93f is provided. In the fluid pressure control bellows container 91
The other end of can be pressed.

The electric power is supplied to the motor 93d by the ceiling rail 1
The power line is installed on the inner surface of the top wall of the
In addition, a brush which is slidably contacted with the power line is provided, and the lead wire connected to the brush is introduced into the moving wall 5 through the hollow center of the suspension rod 4.

Next, the operation of this embodiment will be described.

When the screw rod 93c is rotationally driven by the motor 93d, the nut member 93e screwed to the screw rod 93c is screwed back and forth along the screw rod 93c in a direction parallel to the axis of the fluid pressure control bellows container 91. . When the nut member 93e is located near the right end of the screw rod 93c as shown in FIGS. 1 and 5, the fluid pressure control bellows container 91 is in the most extended state and the output The bellows container 82 is held in the most contracted position by the urging force of the spring 81. as a result,
The upper close-contact member 54 is recessed downward and separated from the ceiling surface C, and the lower close-contact member 55 is retracted upward and separated from the floor surface F. In other words, the upper and lower lifting shafts 6, 7
Is retracted to a position where the locking collars 62, 72 are brought into contact with and locked by the horizontal rails 52a, 52d. Therefore, gaps are formed between the ceiling surface C of the moving wall 5 and between the moving wall 5 and the floor surface F, and the moving wall 5 can be moved along the ceiling rail 1.

After moving the moving wall 5 to a desired position, the motor
When 93d is activated to move the nut member 93e to the left in the drawing, the pressing arm 93f protruding from the nut member 93e presses the end of the fluid pressure control bellows container 91 as shown in FIG. The bellows container 91 is reduced.
When the fluid pressure control bellows container 91 shrinks, the output bellows container
The air pressure inside 82 rises, and the output bellows container 82 expands against the biasing force of the spring 81. In the process in which the output bellows container 81 extends, first, the lower lifting shaft 7 moves downward, and the lower contact member 55 projects toward the floor surface F. When the lower contact member 55 comes into contact with the floor surface F and further lowering is prevented, then the upper lifting shaft 6 is lifted upward, and the upper contact member 54 projects toward the ceiling surface C,
It is pressed against the ceiling surface C. At this time, since the expansion and contraction mechanism 8 can freely move up and down, the upper contact member 54 and the lower contact member 55 can be pressed against the ceiling surface C and the floor surface F with an equal force if the influence of gravity is ignored. become. If necessary, the elevating shaft 7 may be urged upward by a spring (not shown) to cancel the influence of gravity. Moreover, since the bellows container 82, 91 is filled with a compressive fluid such as air, the bellows container 82 has elasticity, and the upper and lower contact members 54, 55 are attached to the ceiling surface. C
And, it will be in elastic contact with the floor surface F. Therefore, the upper and lower compression members 54 and 55 can be brought into close contact with the ceiling surface C and the floor surface F without difficulty, and the sound insulation performance and the light shielding performance can be effectively improved.

The extension mechanism is not limited to the one in the above embodiment, and may be, for example, a cylinder type with a built-in piston.

Further, the pressure control means is not limited to the electric type as described above, but may be a means in which the fluid pressure control bellows container can be expanded and contracted by a manual operation. Specifically, for example, a handle is detachably attached to one end of the threaded rod of the above-described embodiment, and the nut member is advanced and retracted by operating the handle to expand and contract the fluid control bellows container. You may do it.

Furthermore, the close contact member is of course not limited to the embodiment described above, and for example, as shown in FIG. 7, one side shield plate portion 154a ₁ and the other side shield plate portion 154a _{2 are provided.} May be integrally connected via the horizontal plate portion 154b.

Further, the moving wall may be configured to be driven by a motor so as to be self-propelled.

EFFECTS OF THE INVENTION Since the present invention is configured as described above, it is not always necessary to provide an elastically deformable portion in the middle of the elevating shaft, it is bulky, and an unreasonable force easily acts on the operating shaft or the like. The upper and lower close contact members can be reliably and smoothly projected and retracted without using the four-point link mechanism. Therefore, the structure can be simplified, and the weight of the moving wall can be reduced by reducing the number of heavy metal parts as much as possible.

Moreover, since the expansion and contraction mechanism interposed between the upper and lower lifting shafts can move up and down together with these lifting shafts, the distance from the upper edge of the moving wall to the ceiling surface and the lower edge of the moving wall Even if there is a difference in the distance from the floor surface to the floor surface, the vertical movement of the expansion and contraction mechanism causes a differential pressing action, and the force that presses the upper contact member against the ceiling surface and the lower contact member against the floor surface. It becomes easy to equalize the force. Therefore, it becomes possible to perform good light shielding and sound insulation. In particular, since a compressive fluid such as air is used as the working fluid, the upper and lower contact members are elastically attached to the ceiling surface and the floor surface without providing an elastic expansion / contraction portion in the middle of the lifting shaft. It is possible to make contact with each other, and it is possible to reasonably improve the sound insulation performance and the light shielding performance while simplifying the structure.

Further, if the expansion / contraction mechanism has a bellows container, it is possible to reduce the number of parts and simplify the structure.

Further, if the fluid pressure control means also has a bellows container, it becomes possible to seal working fluid such as air in a state where the sliding seal portion is completely eliminated. Therefore, the leakage of the working fluid can be reliably prevented, and the maintenance and inspection can be facilitated.

Further, if the fluid pressure control bellows container has an effective diameter smaller than that of the output bellows container, the operating force can be amplified and transmitted to the elevating shaft, which tends to complicate the structure. The operating force can be reduced without using a mechanical booster mechanism or the like. Therefore, the operating part can be made compact, and in the case of the electric type,
It is possible to reduce the size of motors and speed reducers. Therefore, it is particularly advantageous for reducing the weight of the entire moving wall.
