Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a movable partitioning device used for partitioning floors of hotels, offices, etc. as required.

[Prior Art] This type of movable partition device has a ceiling rail with a continuous opening in the bottom wall fixed to the ceiling of another object, and a plurality of moving bodies can run within this ceiling rail. In addition to placing the
A suspension rod is attached to the intermediate portion of each of these traveling bodies, and the lower ends of the suspension rods are passed through the opening and suspended below the ceiling rail. The movable wall is suspended and supported by the pair of suspension rods, respectively, so that the movable wall can be moved along the ceiling rail. When partitioning a floor by such movable walls, these movable 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. Furthermore, in order to close the gap between the upper edge of the movable wall and the ceiling surface and the gap between the lower edge of the movable wall and the floor surface, which were necessary during the movement, from the upper and lower edges of the movable wall. The upper and lower contact members are made to protrude and are brought into close contact with the corresponding ceiling surface and floor surface, respectively.

The upper and lower contact members are moved to protrude and retract by a contact member drive mechanism built into the movable wall. The conventional close member drive mechanism includes an operating shaft having two types of screw threads with opposite threads, a pair of nuts screwed onto each thread of the operating shaft, and a link member with a rhombic shape. 4 with the left and right pivot points pivoted to each nut.
It is equipped with a point link, and an elevating shaft that connects the upper and lower pivot points of the four-point link and the upper and lower contact members, respectively, and the operating shaft is supported by the frame of the movable wall. .

[Problems to be Solved by the Invention] With such a structure, the nut screwed into both threaded portions of the operating shaft can be rotated by rotating the operating shaft through a detachable handle or the like. When the four-point links move toward each other, the left and right pivot points of the four-point link approach each other, and the upper and lower pivot points move apart. As a result, the upper and lower lifting shafts move apart, the upper contact member is pressed against the ceiling surface, and the lower contact member is brought into close contact with the floor surface. In addition, an elastic expansion and contraction part is provided in the middle of each lifting shaft, so that each lifting shaft can elastically contract when the upper and lower contact members are pressed against the ceiling or floor. There is. However, if there is a relatively large difference between the gap from the top edge of the movable wall to the ceiling surface and the gap from the bottom edge of the movable wall to the floor surface, the top edge of the movable wall may be closed. There is a problem in that the pressing force of the member against the ceiling surface and the pressing force of the lower contact member against the floor surface are significantly different, which adversely affects sound insulation performance and light shielding performance.

Further, with such a configuration, the structure within the movable wall is complicated due to the large number of parts, which requires time and effort to manufacture and adjust, and there are also disadvantages in that it is difficult to reduce the weight of the movable wall.

The present invention aims to solve such problems.

[Means for Solving the Problems] In order to achieve the above objects, the present invention employs the following configuration.

The elevating shafts are disposed so as to be able to protrude and retract toward the ceiling and the floor, and both of the elevating shafts are disposed so as to be able to rise and fall within the movable wall with their base ends facing each other, and each of the elevating shafts is disposed so as to be movable up and down within the movable wall. The expansion and contraction mechanism is configured to expand and contract according to the rise and fall of fluid pressure, and is interposed between both the lifting and lowering shafts, and the expansion and contraction mechanism is configured to expand and contract according to the rise and fall of fluid pressure, and is interposed between both the lifting shafts, and is configured to be able to change the fluid pressure supplied to the telescoping mechanism, and is characterized in that it is arranged so as not to impede the telescoping and raising/lowering operations of the telescoping mechanism.

In order to reduce the number of parts, the expansion/contraction mechanism includes a spring that urges the two shafts toward each other, and a spring that is interposed between the two lifting shafts and is biased by internal working fluid pressure to move the lifting shafts toward each other. It is preferable that the output bellows container be pressed in the separating direction.

To be more specific, flange portions 64.74 are provided on the outer periphery of the proximal ends of the upper and lower lifting shafts 6.7, and the arm 6 is provided near these flange portions 64.74.
5.75 or protruding. The telescopic mechanism 8 includes a tension coil spring 81 which is stretched between the two arms 65.75 and biases the two elevating shafts 6.7 toward each other, and flange portions 64,74 of the two elevating shafts 6.7. An output bellows container 82 is provided between the output shafts 6 and 7, and is biased by the internal working fluid pressure to press the lifting and lowering shafts 6.7 in the direction of separation.

The bellows container 82 is a closed container made of synthetic resin, thin metal plate, or the like, and can expand and contract in the vertical direction according to the pressure of air, which is the working fluid, filled inside.

In a position that does not interfere with the expansion/contraction and lifting/lowering operations of this expansion/contraction mechanism 8,
A fluid pressure control means 9 is provided. The fluid pressure control means 9 is
A bellows container 91 for fluid pressure control having a radius a smaller than that of the bellows container 82 for output, and a bellows container 91 for fluid pressure control.
The fluid pressure control bellows container 91 is configured to be able to be contracted by an electric actuator 93. To be more specific, the edge member 51
A guide tube 95 having end plates 94 on the left and right is installed between the guide tube 95 and the intermediate column 52e, and the fluid pressure control bellows container 91 is accommodated in the guide tube 95 so as to be expandable and retractable. A conduit 92 connected to one end of the bellows container 91 for fluid pressure control is made of a material that can be deformed, and is passed through a hole provided in the end plate 94 and the intermediate column 52e to be connected to the output pipe 92. It leads to a bellows container 82. The lower surface of the guide tube 95 is provided with carefully parallel slits 95a. The electric actuator 93 includes a threaded rod 93c that has one end supported by one end plate 94 via a bearing 93a and the other end supported by the other end plate 94 via a gear box 93b, and a threaded rod 93c that is supported in the gear box 93b. A motor 93d connected to the threaded rod 93c via a gear, a nut member 93e screwed onto the threaded rod 93c, and a nut member 93e protruding from the nut member 93e whose tip is slidably passed through the slit 95a. and a pressing arm 93f inserted into the guide tube 95, so that the other end of the fluid pressure control bellows container 91 can be pressed with the tip of the pressing arm 93f.

In addition, power is supplied to the motor 93d by installing a power line on the inner surface of the ceiling wall of the ceiling rail 1, providing a brush on the running body 3 that comes into sliding contact with the power line, and connecting a lead wire connected to the brush. , and is introduced into the movable wall 5 through the axial hollow part of the suspension rod 4.

Next, the operation of this embodiment will be explained.

When the threaded rod 93c is rotationally driven by the motor 93d, the nut member 93e screwed onto the threaded rod 93c moves back and forth along the threaded rod 93c in a direction parallel to the axis of the bellows container 91 for fluid pressure control. .

Therefore, when the nut portion +4' 93e is located near the right end of the threaded rod 93c as shown in FIGS. 1 and 5, the fluid pressure control bellows container 91 is in the most extended state. Yes, the output bellows container 82 has a spring 81
It is held at the most contracted position by the urging force of. As a result, the overwriting contact member 54 retracts downward and moves away from the ceiling surface C, and the lower writing contact member 55 retracts upward and moves away from the floor surface F. In other words, the upper and lower lifting shafts 6.7 have their locking collars 62.72 connected to the horizontal beams 52a15.
It has been pulled in to the position where it comes into contact with 2d and is locked.

Therefore, between the movable wall 5 and the ceiling surface C, and between the movable wall 5
A gap is formed between the movable wall 5 and the floor surface F, and the movable wall 5 can be moved along the ceiling rail 1.

After moving the movable wall 5 to a desired position, the motor 93d is activated to move the nut member 93e to the left in the figure, and as shown in FIG.
The pressing arm 93f protruding from presses the end of the bellows container 91 for fluid pressure control, and the bellows container 91
shrink.

When the fluid pressure control bellows container 91 contracts, the air pressure inside the output river bellows container 82 increases, and the output bellows container 82 expands against the biasing force of the spring 81 . In the process of extending the output bellows container 81, the lower elevating shaft 7 moves downward and the draft contact member 55 protrudes toward the floor F.

When the lower contact member 55 comes into contact with the floor surface F and is prevented from further lowering, the upper elevating shaft 6 is then lifted upward, and the upper lower contact member 54 protrudes toward the ceiling surface C. ,
It is pressed against the ceiling surface C.

At this time, since the telescopic mechanism 8 can move up and down to the zero peak, the upper writing contact member 54 and the lower writing contact member 55 are applied to the ceiling surface C and the floor surface F with equal force, if the influence of gravity is ignored. It will be forced upon you. Note that, if necessary, the lifting shaft 7 may be biased upward by a spring (not shown) to cancel the influence of gravity. Moreover, the bellows container 8
2. Since the inside of the bellows container 82 is filled with compressible fluid such as air, the bellows container 82 has elasticity.
The upper and lower contact members 54 and 55 are brought into elastic contact with the ceiling surface C and the floor surface F. Therefore, these upper and lower pressure line members 5
4.55 can be easily and reliably brought into close contact with the ceiling surface C and the floor surface F, and the sound insulation performance and light insulation performance can be improved to a nail-like effect.

It should be noted that the telescopic mechanism is of course not limited to that of the embodiment described above, and may be of a cylinder type with a built-in piston, for example.

Furthermore, the pressure control means is not limited to the electric type described above, but may be one that allows the fluid pressure control bellows container to be expanded and contracted by manual operation. Specifically, for example, a handle is removably attached to one end of the threaded rod of the above embodiment from the outside, and by operating the handle, the nut member is moved forward and backward, and the bellows container for fluid control is expanded and contracted. You can do it like this.

Furthermore, the close contact members are of course not limited to those of the embodiments described above. For example, as shown in FIG.
4a2 may be integrally connected via the horizontal plate portion 154b.

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

[Effects of the Invention] Since the present invention has the above-described configuration, it is not necessarily necessary to provide an elastic deformation part in the middle of the elevating shaft, and it is bulky and easy to apply unreasonable force to the operating shaft, etc. The upper and lower contact members can be reliably and smoothly projected and retracted without using a four-point link mechanism. Therefore, it is possible to simplify the structure and reduce the number of heavy metal parts as much as possible, thereby reducing the weight of the movable wall.

Moreover, the telescopic mechanism interposed between the upper and lower elevating shafts can move up and down together with these elevating shafts, so the distance from the upper edge of the movable wall to the ceiling surface,
Even if there is a difference between the distance from the lower edge of the movable wall to the floor surface, the vertical movement of the telescoping mechanism induces a differential pressing action, and the force that presses the upper contact member against the ceiling surface and the lower It becomes easy to equalize the force with which the contact member is pressed against the floor surface.

Therefore, it becomes possible to effectively block light and sound.

Moreover, if the expansion/contraction mechanism has a bellows container, the number of parts can be particularly reduced and the structure can be simplified.

Furthermore, if the fluid pressure control means also has a bellows container, it becomes possible to seal the working fluid such as air without any sliding seal portion. Therefore, leakage of the working fluid can be reliably prevented and maintenance and inspection can be facilitated.

In addition, if the bellows container for fluid pressure control has a smaller effective diameter than the bellows container for output, the operating force can be amplified and transmitted to the lifting shaft, which tends to complicate the structure. The operating force can be reduced without using a mechanical booster or the like. Therefore, the operating part can be made more compact, and in the case of an electric type,
It is possible to downsize the motor and reducer. Therefore, it is particularly advantageous in reducing the weight of the entire moving wall.

If a compressible fluid such as air is used as the working fluid, the upper and lower contact members can be brought into elastic contact with the ceiling and floor surfaces without the need to provide an elastic stretchable part in the middle of the lifting shaft. This makes it possible to simplify the structure and reasonably improve sound insulation performance and light shielding performance.
