Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rolling device for a rail for a moving wall which is movably suspended and supported by a rail laid on the ceiling side.

[0002]

2. Description of the Related Art In many cases, a ceiling hanging type moving wall is installed as a partition wall for a hall having a vast area. When required, the moving wall is moved along the rail to function as a wall for partitioning a hole or the like, and when it is not necessary, it is densely housed in one place for storage.

However, depending on the spatial form of the installation location of the moving wall, the place where the moving walls are densely packed and stored may be behind a pillar or a narrow place. It often takes. For example, in order to change the laying direction of the rails by 90 degrees, it is necessary to lay a cable rail with a relatively large radius in order to smoothly move while changing the direction of movement of each panel-shaped moving wall. When there are obstacles such as pillars and beams, it is often not possible to lay a track with a pattern using a large radius curve rail.

Each moving wall W1 to W7 is provided with two traveling wheels C, which are swingable, near the left and right ends of the upper part of each moving wall W1 to W7, and the upper surface of each rail 1, 1R, 11a, 11b, 11c. When each traveling wheel C rolls, the traveling wheel C is formed so as to move along the rail 1 to the expansion side or the storage side of the moving wall. In each of the rails 1, 1R, 11a, 11b, 11c, G is a guide groove through which the connecting rod R (see FIG. 3) connecting the traveling wheel C and the walls W1 to W7 passes, and this groove G will be described later. The switch devices P1 and P2 of the present invention are also formed. Hereinafter, the switch device P1 of the present invention will be described with reference to FIGS.

2 to 4, reference numeral 2 is a base block, in which two base rectangular base plates 2a and 2b are spaced.
The holes 2d and 2e are formed coaxially at two locations near the left and right sides of the upper and lower base plates 2a and 2b. Also, the lower base plate
A guide groove G through which a rod R connecting the traveling wheel C and the moving wall passes is formed in 2b so as to pass through the center of each hole 2e.

Thrust bearings 3a are mounted in the two holes 2d of the base plate 2a, and a mounting shaft 3b of a rail block 3c, which will be described later, is mounted on each bearing 3a. On the lower surface of each shaft 3b, a circular rail block 3c having a lower end outer peripheral shape which is loosely inserted into the hole 2e of the base plate 2b is fixed by bolting. The rail block 3c has a hollow inside, which has a size to receive the traveling wheel C of the moving wall, and has a supporting surface 3d for supporting the traveling wheel C from the lower surface and a groove 3e communicating with the groove G. Has been formed.

On the other hand, the pinion 3f is provided on the upper portion of each shaft 3b.
Is attached, and the rotation force is transmitted to the pinion 3f, whereby the rail block 3c integrated with the shaft 3b is integrated.
Are formed to rotate. Each pinion 3f
A rack 4b slidably supported by a slide guide 4a is meshed therewith, and each rack 4b is elastically connected to a slide rod 4c via a spring 4d and a connecting rod 4e. Each slide rod 4c can be freely moved back and forth in the left-right direction by its drive source 4f.

Reference numerals 4g and 4h denote mechanical markers provided near the left and right ends of the rod 4c. Both markers 4g and 4h correspond to sensors 4i and 4j by limit switches provided corresponding to the respective markers. By detecting the arrival of the respective markers 4g, 4h in contact with each other, the drive source 4f is controlled as the end of the advancing or retreating operation of the rod 4c.

On the other hand, a dog 3g is provided on the circumference of each pinion 3f, and stoppers 3h and 3i are arranged at both ends of a rotation angle of 90 degrees here corresponding to the dog 3g. Each pinion 3f is formed so as not to rotate more than 90 degrees between the pair of stoppers 3h and 3i due to inertia or the like.

As shown in FIG. 4, with respect to each of the rail blocks 3c described above, a limit switch 5a which functions as a sensor for starting a drive source 4f for rotating the rail blocks 3c angularly is provided. The base plate 2a, 2b of the base block 2 is provided on a cover peripheral wall 2f provided so as to surround the block 3c. Therefore, the cover peripheral wall 2f acts as a stopper for the traveling wheel C in the guide groove G of the base block 2, but a cutout 2g is formed in the portion through which the traveling wheel C passes. A part of the cover peripheral wall 2f is formed in the movable cover 21f, and is formed so as to function as a stopper that selectively blocks the guide groove G that serves as a passage for the traveling wheels C in the base block 2. (See Figure 4).
This movable cover 21f is provided with a limit switch 51a, which is used when it functions as a stopper.
51a functions the same as the limit switch 5a described above. In addition, 2h is a slide drive source of the movable cover 21f, 2i is a slide guide, and 2j is a connecting member between the drive source and the cover 21f.

On the other hand, with respect to the guide groove G formed on the lower base plate 2b, in order to detect passage of the predetermined moving walls W1 to W5, a passage sensor 5b (see FIG. 4) using a proximity switch or the like. (Only a part of which is shown) is provided, and the above constitutes an example of the switching device P1 of the present invention. Here, another example of the shifting device P2 in the present invention is the above-described example of the shifting device P1.
2 has the same structure as the switching device P1 shown in FIG. 2 and is symmetrically arranged in the vertical direction as shown in FIG.

Next, an operation example of the shifting devices P1 and P2 of the present invention will be described with reference to FIG. It is assumed that the moving walls W1 to W7 shown by the chain line in FIG. 1 are in the housed state in the state shown by the chain line. In this state, the moving walls W1 and W2 are
Since it is on the branch rail 11a, it can be moved to the rail 1 on the deploying side of the moving wall (right in the figure) by moving it through the curve rail 1R to the left in the figure as it is, The moving walls W3 to W5 cannot move the running wheels C on the deploying side rail 1 unless the moving walls W3 to W5 are changed to the branch rail 11a by the action of the rolling device P1 of the present invention. Also, moving walls W6 and W7
Also, due to the operation of the present invention, the shifting device P2, the rail 11c
To a branch rail 11 continuous with the rail 1 on the deployment side parallel to it
If you do not change to b, you will not be able to run along Rail 1 on the deployment side.

The turning device P1 of the present invention has a moving wall in the example of FIG.
In order to deploy and move W2, it is necessary that both the rail blocks 3c and the supporting surface 3d of the traveling wheel C and the groove 3e are linearly continuous with the branch rail 11a. In the device P1 of the present invention shown in FIG. 2, this continuous state is a dog provided on the pinion 3f.
It is assumed that 3g is realized by being in contact with the stopper 3h (see FIG. 2). When the pinion 3f is in the position of the rotation angle described above, the rail block 3c integrated with the pinion 3f via the shaft 3b is in the direction shown in FIG. 3, so that the traveling wheel C of the moving wall W2 is the same as that of the device P1 of the present invention. It is possible to pass through the branch rail 11a that is in linear communication with the rail blocks 3c, 3c, and move to the rail 1 on the deploying side in the retracted posture.

In the above-mentioned device P1 of the present invention, if the two rail blocks 3c remain in the orientation shown in FIG.
The moving walls W3 to W5 on the rail of S1 cannot be transferred to the rail block 3c. Therefore, in this switching device P1,
By activating the drive source 4f and moving the slide rod 4c in the state shown in FIG. 2 to the right, the left and right pinions 3f are simultaneously rotated clockwise by 90 degrees. The right movement of the rod 4c is driven by the marker 4h coming into contact with the sensor 4j.
The 4f is stopped, and the dogs 3g of the left and right pinions 3f are regulated by abutting the stoppers 3i on the left side of the drawing.

When the direction of the rail block 3c is changed by 90 degrees in this way, the direction of the rail block 3c becomes the direction in which it communicates with the rail 1'of the storage portion S1, so that the left and right running wheels C of the moving wall W3 are
It is possible to transfer from the rail 1'of the storage portion S1 to the left and right rail blocks 3c whose directions have changed. The transfer at this time is detected by the limit switch 5a in FIG. 4, and the orientation of the rail block 3c is held for a predetermined time, for example, 2 seconds. Since the groove 3e of the supporting surface 3d of the traveling wheel C in the rail block 3c in this state is orthogonal to the guide groove G of the branch rail 11a connected to the deploying rail 1, it cannot be transferred to the rail 11a as it is. . In the present invention, the limit switch 5a detects the traveling wheel C, and the drive source 4f is driven to the opposite side to the above side on condition that a predetermined time has elapsed. The drive source 4f is actuated to move the slide rod 4c to the left to rotate the pinion 3f in the counterclockwise direction to move the marker.
When 4g comes into contact with the sensor 4i, the drive source 4f is stopped, and this rotation is restricted by the dog 3g by the stopper 3h.
By doing so, the traveling wheel C of the moving wall W3, while being supported by the supporting surface 3d of the rail block 3c, changes its direction 90 degrees counterclockwise integrally with the rail block 3c. 3c is turned along with the supported traveling wheels C, and is in the same direction as the branch rail 11a that is continuous with the rail 1 on the deploying side, so that the moving wall W3 is the moving wall W1 that was previously deployed and moved. It can be transferred to rail 1 on the deploying side in the same way as W2.

As is apparent from the above description, in the base block 2 of the switch device P1 of the present invention, the rail block 3c is provided.
90 degrees clockwise and counterclockwise, and the rails 1'to the rail block of the storage section S1 of the moving walls W4 and W5 in between.
By moving to 3c and changing direction, moving walls W4 and W5
It can be sequentially moved to the rail 1 on the deploying side. When the moving walls W1 to W5 have been transferred to the rail 1 on the deploying side by using the device P1 of the present invention as described above, the moving walls W6 and W7 are expanded from their storage portions S2 by using the device P2 of the present invention. Move to rail 1 on the side. Next, an operation example of the switching device P2 will be described.

The turning device P2 of the present invention is as shown in FIGS. 5 to 7, but in this case, on the extension lines of the branch rails 11b and the rails 11c of the storage section S2 parallel to the branch rails 11b, respectively, Since the two rows of the rail blocks 3c are provided as one set on the right, the movements of the moving walls W6 and W7 on the rolling device P2 of the present invention increase accordingly.

Now, in the direction of the lower half rail block 3c in the device P2 shown in FIG. 5, the marker 4g is in contact with the sensor 4i and the dog 3g of the pinion 3f is restricted by the stopper 3i. Then, as shown in FIG. 7, it is assumed that the support surface 3d of the traveling wheel C and the groove 3e of the block 3c are in a state of being continuous with the rail 11c of the storage portion S2. In this state, the moving wall W6
The left and right traveling wheels C are moved in the right direction in FIG. 1 from the rails 11c of the storage section S2 to the support surfaces 3d of the left and right railroad blocks 3c. When the traveling wheel C rides on the support surface 3d of the lower right rail block 3c, the limit switch 5a detects it and
The posture is maintained for a predetermined time and the drive source 4f is moved to the right.

In this way, since the slide rod 4c on the lower half side of FIG. 5 is moved to the right, the pinion 3f meshing with the rack 4b that moves to the right integrally with the rod 4c rotates counterclockwise, When rotated 90 degrees, the marker 4h comes into contact with the sensor 4j to stop the drive source 4f, and the pinion 3f dog
Since 3g abuts on the stopper 3h and its rotation is restricted, the direction of the rail block 3c coincides with the guide groove G formed in the base plate 2b, and as a result, the moving wall W6 is moved to the base. Board
The base plate 2b is advanced (upward in FIG. 2) along the groove G of 2b. In this shifting device P2, the four rail blocks 3c are always in the same posture with each other, and the sequences of the individual drive sources 4f are set so that they are simultaneously rotated, Figure 5 upper half rail block 3c
Is in the same direction as the lower half rail block 3c in synchronization with the above operation.

Moving wall W6 advanced along the guide groove G
2 is a rail block on the upper half side of FIG. 2 in which the supporting surface 3d of the running wheel C and the groove 3e are held in the direction in which they are aligned with the guide groove G.
The traveling wheel C can transfer to the supporting surface 3d of 3c.

It is detected by the limit switch 5a that the left and right running wheels C of the moving wall W6 ride on the support surfaces 3d of the left and right railroad blocks 3c on the upper half side of FIG. After a lapse of a second, in order to change the direction of the rail block 3c on the upper half side of FIG. 5 by 90 degrees, the drive source 4f on the upper half side operates to move the slide rod 4c on the upper half side of FIG. ) Let me. As a result, a rack integrated with the rod 4c
The pinion 3f meshed with 4b is rotated 90 degrees counterclockwise.This 90 degree rotation is detected by the marker 4g of the rod 4c.
The drive source 4f is stopped by contacting 4j, and
The dog 3g on the pinion 3f is regulated by coming into contact with the stopper 3i. In this way, when the rail block 3c on the upper half side of FIG. 2 rotates 90 degrees counterclockwise, the block 3c concerned
Since the running wheel support surface 3d and the groove 3e are in the direction of communicating with the guide groove G of the branch rail 11b which is continuous with the rail 1 on the deployment side,
In this state, the moving wall W6 can be moved to the rail 1 on the deploying side.

In the movement from the rail 11c of the storage portion S2 of the moving wall W6 to the branch rail 11b, each rail block 3c rotated by 90 degrees reverses the previous rotation after passing through the moving wall W6. It is rotated 90 degrees to the side to prepare for the next movement of the moving wall W7. Therefore, the operation of the rolling device P2 of the present invention in the movement of the moving wall W7 to the deploying side rail 1, particularly the operation of each rail block 3c, is controlled by the same sequence as that of the moving wall W6.

The moving walls W1 to W7 that are moved to the rail 1 on the deploying side as described above are deployed at the positions of the moving walls W5 'to W7', as shown in part by the one-dot chain line in FIG. To complete. Here, C'indicates the position of the traveling wheel at the completion of deployment. The expansion pattern shown in the figure is an example, and it goes without saying that expansion patterns in other forms are possible. As described above, the moving walls W1 to W7 in which the first moving wall W1 to the seventh wall W7 are sequentially deployed are moved to the respective storage portions in the reverse order of the time of deployment, In that case, of course, the shifting devices P1 and P2 of the present invention are operated.

When the moving walls W1 to W7 are housed, the operation sequence of each rail block 3c in each of the shifting devices P1 and P2 of the present invention is only opposite to that in the unfolding operation. Are substantially the same and will not be described. The above explanation is
Although the movement of each moving wall W1 to W7 is performed manually, and the rotation angle of the rail block 3c is 90 degrees, the positioning angle of the rail block 3c and the holding time of the angle are arbitrarily set. Can be changed, and the movement of the moving wall is
A self-propelled type such as a motor may be used. In this case, maintaining the positioning angle of the rail block 3c and controlling the driving / stopping of the moving drive source of each moving wall are controlled by the operation of each drive source.
It is performed by controlling the can. Furthermore, when there are three or more traveling wheels C on each moving wall, each switching device P
Of course, the set of rail blocks 3c of 1 and P2 also corresponds to the number of running wheels of one moving wall.

[0029]

The present invention is as described above, and the space where the curve rail cannot be used due to the space relations or obstacles, or the space for storing the space is efficiently used. In order to correspond to the case where you want to set well, one rail and a base block formed with a guide groove for entering the traveling wheel that communicates with another rail in a direction intersecting with the rail or a direction parallel to the rail, A support surface for a running wheel that has a guide groove that selectively connects to the guide groove that communicates with the one rail and another rail by rotating and changing the direction, and that has the same cross section as each rail. A rail block having a number of running wheels provided on one moving wall and having the same spacing as the running blocks are rotatably mounted by a driving force, and the rotation angle of the rail block is controlled. Therefore, an efficient rail laying layout It is possible to achieve.

Further, the switching device for that purpose is embodied in a device having a very simple structure and having one turn (direction change) or two turns (direction change) of an angle required for direction change. Therefore, it is possible to reduce the number of parts by sharing the parts, facilitating the manufacture thereof, or speedily and accurately controlling, and therefore, it is extremely useful as a rolling device for rails for moving walls. It is useful.
