Description

[Detailed description of the invention] (Field of industrial application) This invention fixes a movable partition suspended at any location on rails laid on the ceiling so that it can be moved, and connects the partition to the ceiling and floor. It relates to a device that completely closes the gap between surfaces, and in particular,
It is effective when applied to a downward U-shaped partition for installing a door.

(Prior Art and Purpose of the Present Invention) It is unavoidable that a movable partition has a slight gap between the ceiling and the floor.

As a result, drafts can blow into a room that is being heated, or cold air can escape from a room that is being cooled, which is not good for heat retention.
As disclosed in Publication No. 48870 or Japanese Utility Model Application Publication No. 58-85081, a pressure welding material that can be raised and lowered is provided at both the upper and lower ends of a partition plate, and the pressure welding material can be raised and lowered by operating a handle on the side end surface of the partition plate. Various devices have been proposed that are pressed against the ceiling and floor to fix the partition and close the gap between the upper and lower sides.

However, these conventional devices all have a link mechanism made of steel and raise and lower both the upper and lower press members at the same time, so the amount of movement is always the same.

Therefore, when the upper and lower gaps have different widths due to irregularities in the ceiling or floor, there is a problem in that the wider gap is not completely closed and the partition is not sufficiently fixed.

The present invention has been made to solve the above-mentioned drawbacks.

(Structure of the present invention) The present invention fits into grooves provided on both the upper and lower end surfaces of a partition plate so as to be able to slide vertically, and is biased outward with a spring and directed inward. There is a press-contact plate with a movable pulley pivotally mounted on the free end of a lifting rod fixed to the wall, which is approximately the same length as both the upper and lower ends of the partition plate, and a press-contact plate that is installed inside at a key point on one side of the partition plate, and has a movable pulley pivoted on the free end of a lifting rod fixed to the partition plate. A gear device that raises and lowers a drive rod pointing in the vertical direction by operating a handle, and one end of which is fixed to one end of the drive rod of the gear device.
The movable pulley of each press-contact plate is hung around the movable pulley in turn, and the other end is fixed to a key point inside the partition plate, and by raising and lowering the drive rod, each press-contact plate is pulled inward or loosened together with the movable pulley. Made of wire rope and more.

(Effects of the present invention) Since the present invention is configured as described above,
As explained in detail in the examples, the upper and lower pressure welding materials move up and down in response to irregularities in the ceiling and floor, so it is possible to completely close the upper and lower gaps of different widths and fix the partition. I can do it.

Moreover, since a wire rope is used as a linking member between the pressure contact plate and the gear device, the same member can be used for various partitions of different sizes and shapes by simply adjusting the length of the wire rope.

(Example) The drawing shows a downward U-shaped partition for installing a door butterfly to which the present invention is applied, where 1 is a partition plate, 2 is a frame, 3 is a door mounting frame, and 4 is a partition plate. 1
This is a suspension roller device that is suspended from a rail (not shown).

On the outer surfaces of the lower left and right horizontal frame rods 2a and the upper horizontal frame rod 2b, there are grooves having the same length as each other.
Channel-shaped guide rods 5 and 6 with external openings are installed horizontally, and pressure welding members 7 and 8 having approximately the same length as the guide rods 5 and 6 are respectively fitted to be movable up and down.

As shown in FIG. 2, a lifting rod 9 is erected at the center of each lower pressing plate 7. It passes through both upper and lower pieces 10a and 10b of a U-shaped guide fitting 10, which is fixed directly above the horizontal frame rod 2a, so as to be able to rise and fall.

Both pieces 10a of the guide fitting 10 in the lifting rod 9,
A coiled compression spring 12 is wound between the horizontal pin 11 penetrating between the horizontal pins 11 and the upper piece 10a, and a movable pulley 14 with a bearing fitting 13 and facing in the front-rear direction is mounted on the upper end of the lifting rod 9. is installed at the center.

The pressure contact plate 7 is urged downward together with the lifting rod 9 by a spring 12.

The upper left and right corners of the partition plate 1 are also made of the same material as the left and right lower ends described above, and are vertically symmetrical.
The upper press member 8 is urged upward.

Bearing fittings 1 are attached to both left and right ends of the upper surface of the door mounting frame 3.
5, a fixed pulley 16 facing in the front-rear direction is pivotally installed.

Slightly below the center of both the inner and outer sides of the vertical frame rod 2c on the right side of the frame body 2, coaxial through holes 17, 17 are bored, and at the same location on the inner surface, a gear device 18 as described below is provided. A casing 19 is fixedly installed.

A worm 20 facing in the left-right direction and a worm wheel 21 that engages with the worm wheel 21 are pivotally installed in the casing 19. The outer end of the worm 20 is coaxially connected and freely passes through the through hole 17 inside the frame 2. Engagement cylinder 2
2 are connected to each other, and an engagement groove 23 facing in the diametrical direction is cut at the outer end thereof.

A coaxial pinion 24 that is integrally superimposed on the side surface of the worm wheel 21 is engaged with a drive rod 25 that is a rack that passes vertically through the casing 19 so as to be able to move up and down.

A wire rope 26, one end of which is fixed to the lower end of the drive rod 25, connects the moving pulleys 14 at the lower right and upper right of the partition plate 1, and the fixed pulleys 1 on the left and right.
6, and the upper left and lower left movable pulleys 14 in turn, and then the other end is fixed to the inner surface of the left vertical frame rod 2c of the frame body 2.

In the partition configured as described above, the drive rod 25 can be raised from the through hole 17 on the outside of the frame body 2 by operating a handle 27 having a head that can engage with the engagement groove 23 of the engagement tube 22. For example, the upper and lower pressing members 8 and 7 connected to each other via the movable pulleys 14 with wire ropes 26 are pulled into the respective guide rods 6 and 5 against the spring 12.

In this state, if the drive rod 25 is lowered by operating the handle 27 after the partition has been moved to a predetermined location, the pressure welding members 7 and 8 will both protrude outward due to the bias of the spring 12. , press against the ceiling and floor.

At this time, if the ceiling or floor surface is uneven and, for example, the lower left gap of the partition is wider than the other gaps, the pressure welding material 7 on the lower left will press after the other pressure welding materials 7 and 8.
The wire rope 26 is fed in, descends independently, and comes into pressure contact with the floor surface, closing all gaps and fixing the partition.

In the above description, devices such as the movable pulleys 14 are provided at both ends of the upper pressure welding material 8, but the center 1
A similar device may be provided at a location to move the press member 8 up and down, and if the partition plate 1 is small, the fixed pulley 16 may be omitted.

Furthermore, the device of the present invention can also be used for rectangular partition plates, which are often used, by, for example, providing a fixed pulley on the central transverse reinforcing rod.
