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 necessary.

[Prior Art] This type of movable partition device has a rail having a continuous opening in the bottom wall fixed to the ceiling, and a plurality of running bodies arranged to be able to run within this rail. A suspension rod is rotatably attached to the intermediate portion of each of these traveling bodies, and the lower ends of the suspension rods are suspended below the rail through the opening. The movable walls are suspended and supported by the pair of suspension rods, respectively, so that the movable walls can be moved along the rails.

In such a movable partition device, the movable wall is generally not only slid like a sliding door, but also movable in various ways for storage in a storage section or the like. Therefore, it is often the case that the rails are provided with branching portions so that the traveling bodies supporting the movable wall can be guided to different routes as necessary.

[Problems to be Solved by the Invention] However, in the conventional system, a guide groove or a guide rail is provided near the center of the rail, and the vehicle runs on the guide surfaces provided on the inner surface of the guide groove or on both sides of the guide rail. A guide member (a guide roller or a slider) protruding from the upper surface of the body is selectively guided to select a route for the traveling body at the branching portion.

Therefore, for example, a pair of traveling bodies that suspend and support each moving wall are first sorted and guided to the same branch rail, and then one traveling body and the other traveling body of the moving wall are further separated. If you want to sort fine branching rails without error, prepare many guide grooves and guide rails with different depths or hanging lengths, and also prepare many types of guide members with different heights. It becomes necessary to use the body. As a result, not only the design and manufacturing become complicated, but also the vertical dimension of the rail increases. That is, in this type of device,
All rails installed on the ceiling must be sized so that the tallest traveling object can pass through, so if the guide member of the traveling object is tall due to complicated route selection, , the entire ceiling rail is affected. However, as the vertical dimension of the ceiling rail increases, not only does its weight increase and the support structure becomes bulky, but also the space above the ceiling material cannot be secured beyond a certain level due to the relationship with beams, etc. As a result, there is a problem in that construction is subject to significant restrictions.

SUMMARY OF THE INVENTION An object of the present invention is to provide a movable partition device that reliably solves these problems and allows each traveling body supporting a movable wall to trace a predetermined route without error.

[Means for solving the problems] In order to achieve such objects, the present invention has the following features:
It is characterized by adopting the following configuration.

That is, the movable partition device according to the present invention includes a rail that is fixed to a ceiling and has a continuous opening in its bottom wall, and a rail that is disposed within this rail and has its middle portion facing the opening. a plurality of running bodies capable of traveling in a state in which the running bodies are mounted; a suspension rod that is rotatably attached to the intermediate portion of each of these running bodies and whose lower end is suspended below the rail through the opening; and a pair of suspension rods. a movable wall that is suspended and supported, a lower guide roller that is pivoted on a portion of the lower surface of each of the traveling bodies that is deviated from the suspension rod and rolls into contact with the edge of the opening; an upper guide roller that is pivoted at a portion deviated from the suspension rod and whose height is individually set; a slider that protrudes from the top surface of the traveling body; and a central guide rail that is provided along the center of the rail. and a side guide rail provided at a position offset laterally by a certain distance from the center of the rail, and at least one of both sides of the center guide rail and the inner side of the side guide rail. A selection guide surface is formed that selectively engages the upper guide roller to select the traveling route of each traveling body in the branching portion, and a selection guide surface that engages a slider on an outer surface of the side guide rail to selectively engage the traveling body The vehicle is characterized by a deviation prevention surface that prevents the vehicle from deviating from the selected regular route.

[Function] In the part where the rail does not branch, the direction of movement of each traveling body is determined by the guiding action of the lower guide roller that contacts the edge of the opening of the rail, and the moving wall follows the rail. It will slide smoothly along the In a curved portion of the rail, the lower guide roller and the upper guide roller work together to maintain the posture of the traveling body in a stable state while appropriately changing its traveling direction. can.

At the branching portion of the rail, the traveling route of the traveling body is selected depending on whether or not the upper guide roller of the traveling body engages with the selected guide surface. That is, since the height of the upper guide roller of each traveling body is set individually, there are cases where the upper guide roller contacts the selected guide surface and cases where the upper guide roller does not contact the selected guide surface. Therefore, when the upper guide roller comes into contact with the selection guide surface, the traveling object is guided by the selection guide surface and follows one route, and the upper guide roller does not come into contact with the selection guide surface. In that case, the other route will be followed. Therefore, by combining the engagement and disengagement relationship with the selection guide surface based on the difference in the arrangement position of the upper guide roller, it is possible to automatically select various travel routes. In particular, in the present invention, the selection guide surface can be formed by appropriately and effectively utilizing both side surfaces of the central guide rail and the inner surfaces of the side guide rails that can be provided offset to the left and right. Therefore, the selection guide surface can be diversified, and complex route selection can be performed without having to prepare many different heights of the upper guide roller. Therefore, it is possible to effectively prevent the height of the rail from increasing.

In addition, in the case where only the upper guide roller is provided on the upper surface of the traveling body, if the traveling route is selected passively, that is, the traveling body does not reach the branching part without the upper guide roller engaging with the selected guide surface. If an unexpected external force acts on the end of the moving wall while attempting to pass, there is a risk that the moving object may stray onto an unplanned route. However, in the present invention, when the traveling body attempts to proceed to a route other than the traveling route selected by the upper guide roller and the selected guide surface, the slider engages with the departure prevention surface and prevents it. This will prevent this. Therefore, even if an unexpected external force is applied to the movable wall, each traveling body can be made to follow the planned route without error.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

Next, the operation of this embodiment will be explained.

Figure 1 shows the movable walls 6 ₁ to 6 _o connected to the straight rail section 1.
Figure 1 shows the state in which the room is partitioned by being pulled out. From this state, first, the telescope panel portion 6a ₁ of the first movable wall 6 ₁ is pulled in and separated from the wall 12. After that, when the movable wall 6 ₁ is made to advance in the longitudinal direction along the rail 2, the upper guide roller 7 of the traveling body 4 _a of the first movable wall 6 ₁ first moves.
1 _L is in rolling contact with the selection guide surface 41 ₁ of the central guide rail 43 provided in the first branch portion 13,
It is guided to the first movable wall storage section ₁₅₁ side. When the traveling body 4 _a on the front end side of the moving wall 6 ₁ passes through the second branch portion 14 ₁ , the short upper guide roller 71 _L moves toward the selection guide surface 42 ₁ .
Since the traveling body _4a cannot come into contact _with
6 ₁ to the straight rail section 17 ₁ . In this case, since the upper guide roller _71L is not actively guided by the selection guide surface ₄₂₁ , if an unexpected force in the thickness direction is applied to the movable wall ₆₁ , the traveling body 4a will not be selected. You may try to proceed to a route other than the route specified. In this case, the slider 81 comes into contact with the departure prevention surface 45 ₁ , and the traveling body 4 _a follows the unselected route, that is, the other branch end 1
This will prevent you from being led to a route that passes through the 4b ₁ side. On the other hand, when the traveling body 4b on the rear end side of the moving wall ₆₁ passes through the second branch portion ₁₄₁ , the tall upper guide roller _71H comes into rolling contact with the selection guide surface _421. become. Therefore, the traveling body 4 _b is guided toward the other branch end 14 b ₁ by the guiding action of the selection guide surface 42 ₁ and guided to the straight rail portion 18 ₁ .
Therefore, the first movable wall 6 ₁ is supported by both the straight rail portions 17 ₁ and 18 ₁ and accommodated in the first movable wall storage section 15 ₁ .

Next, the upper guide roller _71L of the traveling body 4c of the _second movable wall 62

When the traveling body _4c on the front end side of the moving wall ₆₂ passes through the second branch portion ₁₄₂ , the short upper guide roller _71L can roll into contact with the selection guide surface ₄₂₂ . Therefore, the traveling body _4c travels straight from one branch end _14a2 through the curved rail portion ₁₆₂ to the straight rail portion 1.
7 Guided by ₂ . In this case as well, the upper guide roller _71L is not actively guided by the selection guide surface ₄₂₂ , so if an unexpected force in the thickness direction is applied to the moving wall ₆₂ , the traveling body _4c You may try to proceed to a route other than the selected route. In this case, the slider 81 comes into contact with the deviation prevention surface ₄₅₂ ,
A route for which traveling object 4 _c is not selected, that is,
This prevents them from being led to a route that passes through the other branch end _14b2 . On the other hand, the moving wall 6
When the running body 4 _d on the rear end side of ₂ passes through the second branch portion 14 ₂ , its tall upper guide roller 71 _H comes into rolling contact with the selection guide surface 42 ₂ . Therefore, this traveling body _4d is guided toward the other branch end _14b2 by the guiding action of the selection guide surface ₄₂₂ , and the straight rail portion ₁₈₂
be led to. Therefore, the second movable wall 6 ₂ is supported by both straight rail sections 17 ₂ and 18 ₂ and
It is stored in the movable wall storage section ₁₅₂ .

Similarly, odd-numbered movable walls 6 ₃ , 6 ₅ ... are guided into the first movable wall storage section 15 ₁ , and even-numbered movable walls 6 ₄ , 6 ₆ ... are guided into the second movable wall. Storage part 15
Guided within ₂ . When the movable walls 6 ₁ to 6 _o are to be pulled out to the use position as shown in FIG. 1, the above operation may be performed in reverse.

The first branch portion 113 includes a central guide rail 122 with a short hanging dimension that branches along the rail center N, and a side guide rail 123 with a long hanging dimension that is offset laterally with respect to the rail center N. is provided, and the side surface of the central guide rail 122 is used as a selective guide surface 124 and the side guide rail 12
3 is used as a departure prevention surface 125.

In addition, the second branch portion 114 includes a central guide rail 126 branching along the rail center N;
A side guide rail 127 with a short hanging dimension and offset laterally with respect to the rail center N is provided. Note that the central guide rail 126 has a curved portion 126a having a long hanging dimension, and a straight portion 126b having a short hanging dimension. Then, one side of this central guide rail 126 is selected as the guide surface 128.
In addition, the outer surface of the side guide rail 127 serves as a deviation prevention surface 129.

Further, the third branch portion 115 is provided with a side guide rail 131 that is offset to one side with respect to the rail center N and extends parallel to the rail center N. The side surface serves as a selection guide surface 132, and the outer surface serves as a departure prevention surface 133.

Four types of moving bodies 104 _a , 104 _b , 104 _c , and 104 _d are movably arranged within this rail 102 , and odd-numbered moving walls 106 ₁ ,
106 ₃ ... are supported by the traveling bodies 104 _a and 104 _b , and even-numbered moving walls 106 ₂ and 10
6 ₄ ... are supported by traveling bodies 104 _c and 104 _d .

As shown in FIG. 14, the traveling body _104a includes a short upper guide roller _71L offset to the left of the rail center N, and a short slider _81L located on the right edge of the upper surface. There is. Running body 104 _b

As shown in FIG. 16, the traveling body _104c includes a short upper guide roller _71L that is offset to the right of the rail center N, and a tall slider _81H that is located on the right edge of the upper surface. . As shown in FIG. 17, the traveling body _104d has a tall upper guide roller _71H that is offset to the right of the rail center N.

Therefore, in this embodiment as well, the tall upper guide roller _71H is provided not only on the selection guide surface 128 of the guide rail 126 with a long hanging dimension, but also on the selection guide surfaces 124, 131 of the guide rails 122, 131 with a short hanging dimension. will also be involved. On the other hand, the short guide roller _71L can engage only the selection guide surface 128 formed on the guide rail 126 with a long hanging dimension. Therefore, each branch portion 11 of the rail 102
Selection guide surface 1 provided at 3, 114, 115
24, 128, 132 and the upper guide roller 71
By engaging and disengaging with _L and _71H , a traveling route selection function similar to that in the first embodiment is carried out. As a result, the odd-numbered moving walls 106 ₁ , 106 ₃ ...
The movable walls 106 ₂ , 106 ₄ . . . are stored in the adjacent movable wall storage position 142.

By the way, during such a storage operation, the traveling body _104a that supports the front end side of each of the odd-numbered moving walls 106 ₁ , 106 ₃ . When passing through the first branch portion 113, since the selection guide surface 124 does not actively guide the moving walls 106 ₁ , 106 ₃ . . . , an unexpected force in the thickness direction is applied. In some cases, the traveling object 104a may attempt to proceed to a route other than the selected route. In this case, the slider 81 _L comes into contact with the deviation prevention surface 125, thereby preventing the traveling object 104a from being guided to a route that has not been selected. Note that the slider 81 _L of this traveling body 104a

This will prevent the user from getting lost on the route heading for 118 and 119.

Note that the form of the rail is not limited to that described above, and further modifications can be made without departing from the spirit of the present invention.

[Effects of the Invention] Since the present invention has the above-described configuration, the following effects can be achieved at the same time.

First, a lower guide roller is provided on the lower surface of the running body, and this lower guide roller is brought into rolling contact with the edge of the opening provided in the bottom wall of the rail to regulate the traveling direction of the running body, so that the rail Enforcement becomes easier. In other words, when the guide rollers of the traveling body are in rolling contact with the inner surface of the rail, the rails must be joined so that there are no steps on the inner surface, which requires highly accurate construction. Therefore, if a difference in level occurs as a result, it is difficult to correct it. On the other hand, the opening provided in the bottom wall of the rail is visible even after construction, and even if a step occurs, the step can be easily eliminated by cutting the rail or the like. Therefore, the movable wall can be smoothly moved without causing difficulty in rail construction.

Further, since the upper guide roller is provided on the upper surface side of the traveling body, even if the rail has a curve with a small radius of curvature, the course of the traveling body can be changed in a stable state.

In addition, the height of the upper guide roller is set individually, and a selection guide surface that selectively engages the upper guide roller is provided at the branching part of the rail, so that the traveling route of each traveling body can be determined at the branching part. Automatic selection can be ensured. Therefore, simply by applying a longitudinal force to the movable wall, the movable wall will be guided along a desired preset route. According to this structure, there is no need to provide a movable part at the branching portion, and there is no need for an operation similar to a so-called point switching operation. Therefore, the movement operation for pulling out the movable wall to the use position and storing it in the storage section can be performed reliably and without error. In particular, in the present invention, the selection guide surface can be formed by appropriately and effectively utilizing both side surfaces of the central guide rail and the inner surfaces of the side guide rails that can be provided offset to the left and right. Therefore, the selection guide surface can be diversified, and complex route selection can be performed without having to prepare many different heights of the upper guide roller. For example, if the guidance control is such that two traveling bodies supporting one moving wall are first guided to the same branching route, and then guided to different sub-branching routes, This can be realized using two types of guide rollers with different heights. Therefore, it is possible to effectively prevent the vertical dimension of the rail from increasing.

Furthermore, if an unexpected external force acts on the moving wall at the branching part of the rail and the traveling body attempts to proceed to a route other than the traveling route selected by the upper guide roller and the selected guide surface, the slider will deviate. It is designed so that it can be engaged with a prevention surface to prevent it. Therefore, no matter what kind of external force is applied to the moving wall, it is possible for each traveling object to trace the planned route without error, and the automatic selection function of the traveling route can always be reliably performed. It is possible to obtain the following effects. Moreover, since this deviation prevention surface is formed using the outer surface of the side guide rail, no special member is required and the rail branching portion does not become complicated.
