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 running body is moved by the guide surfaces provided on the inner surface of the guide groove or on both sides of the guide rail. A guide member protruding from the upper surface of the vehicle is selectively guided to select the traveling route of the vehicle 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 proceed the sorting to a branch rail, prepare a number of guide grooves and guide rails with different depths or hanging lengths, and use various types of running bodies with guide members of different heights. The need arises. As a result, not only the design and manufacturing become complicated, but also the vertical dimension of the rail increases. In other words, in this type of device, all the rails installed on the ceiling must be sized so that the tallest traveling object can pass through, so the guide members of the traveling object are necessary for complex route selection. If something tall happens, the entire ceiling rail will be 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.

The present invention aims to reliably solve such problems.

[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 that can run 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; a movable wall that is suspended and supported, a lower guide roller that is pivoted at 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 offset from the suspension rod and whose height is set individually; and an upper guide roller that is provided along the center of the rail and that selectively engages with the upper guide roller for each run at the branching portion. A central guide rail having selection guide surfaces on both sides for selecting the traveling route of the body, and a central guide rail provided at a position offset to one side by a certain distance from the center of the rail and selectively engaged with the upper guide roller to branch. one side guide rail having a selection guide surface formed on the surface on the rail center side for selecting the traveling route of each traveling body in the section; and the upper guide provided at a position offset to the other side by a certain distance from the rail center. The present invention is characterized in that it includes a selection guide surface formed on a surface on the rail center side for selectively engaging the rollers and selecting the traveling route of each traveling body in the branching portion.

[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 moves along 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 selected guide surface based on the difference in the arrangement position of the upper guide roller, various traveling routes can be automatically selected. A central guide rail is provided along the rail, a guide rail on one side is provided at a position offset to one side by a certain distance from the center of the rail, and a guide rail is provided at a position offset to the other side by a certain distance from the center of the rail. Since the upper guide roller of the traveling body is guided by appropriately combining the upper guide rail with the guide rail on the other side, it is possible to select a variety of routes without having to increase the height of the guide rail and upper guide roller. Become. For example, if two types of upper guide rollers with different heights are prepared, a pair of running bodies that suspend and support a moving wall can be selectively guided to the same branch rail by the central guide rail, and one side or the other side can be guided. The rails enable route selection control in which the traveling bodies on one side of the moving wall and the traveling bodies on the other side are further sorted and proceeded to different branching rails. Therefore, according to the present invention, it is possible to perform complicated route selection without having to prepare many types of upper guide rollers with different heights, and it is possible to prevent the vertical dimension of the rail from increasing. .

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 . On the other hand, when the traveling body _4b on the rear end side of the movable wall ₆₁ passes through the second branch portion ₁₄₁ , the tall upper guide roller _71H
It comes into contact with the selection guide surface 42 ₁ of 4 ₁ .
Therefore, this traveling body 4 _b has a selection guide surface 42 ₁
It is guided to the other branch end 14b ₁ side by the guiding action of , and is 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 71 _L of the traveling body 4 _c of the second movable wall 6 _2
2 and is guided toward the second movable wall storage section ₁₅₂ . When the traveling body _4c on the front end side of this moving wall ₆₂ passes through the second branch portion ₁₄₂ ,
Since the short upper guide roller _71L cannot roll into contact with the selection guide surface ₄₂₂ , the traveling body 4
c travels straight and is guided from one branch end 14a ₂ through the curved rail portion 16 ₂ to the straight rail portion 17 ₂ . On the other hand, when the traveling body 4 _d on the rear end side of the moving wall 6 ₂ passes through the second branch part 14 ₂ ,
The tall upper guide roller 71 _H comes into rolling contact with the other side guide rail 44 ₂ selection guide surface 42 ₂ . Therefore, this traveling body 4 _d moves toward the other branch end 1 by the guiding action of the selection guide surface 42 ₂ .
_4b2 side, and is led to the straight rail portion ₁₈₂ . Therefore, the second movable wall 6 ₂ is supported by both the straight rail portions 17 ₂ and 18 ₂ and accommodated in the second movable wall storage portion 15 ₂ .

Similarly, the odd-numbered moving walls 6 ₃ , 6 ₅ ... are the first
The even-numbered movable walls 6 ₄ , 6 ₆ . . _. are guided into the second movable wall accommodating portion 15 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. With such a configuration, each of the movable walls 6 ₁ to 6 ₅ can be suspended by the central guide rail 43 by simply preparing two types of upper guide rollers 71 _H to 71 _L with different heights. Each pair of supported traveling bodies 4 _a to 4 _d is sorted and guided to the same branch rail, and then the movable walls 6 ₁ to 6 ₅ are guided by one side or the other side guide rails 44 ₁ , 44 ₂ . One of the running bodies 4 _a , 4 _c and the other running bodies 4 _b , 4 _d can be further sorted and advanced to different branch rails.

Note that the form of the rail is not limited to that described above, and various 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, a central guide rail provided along the center of the rail, one side guide rail provided at a position offset to one side by a certain distance from the center of the rail, and another guide rail provided by a certain distance from the center of the rail to one side. Since the upper guide roller of the traveling body is guided using the guide rail on the other side, which is installed at a position offset to the side, complicated route selection can be avoided without having to prepare multiple types of upper guide rollers with different heights. can be controlled. Specifically, the guidance control is such that two traveling bodies supporting one moving wall are first guided to the same branching route, and then those traveling bodies are guided to different sub-branching routes. If there is, it is possible to realize this by using two types of upper guide rollers with different heights. Therefore, it is possible to solve the problem that the vertical dimension of the rail becomes unduly large due to complicated branch route selection.

Furthermore, since the moving body is guided entirely by rollers, the moving body can be moved easily with a small force. Therefore, in combination with the above-mentioned automatic route selection function at the branching section, it is possible to guide and store all the movable walls one by one to the required location simply by pressing the multiple movable walls in the longitudinal direction from the terminal end. It also becomes possible.
In this way, it is possible to perform the movement operation without creating a gap between each moving wall, so not only can the movement operation be performed quickly, but also it is possible to move hands and feet between the moving walls. It is possible to reliably prevent accidents such as getting caught, and safety can be effectively improved.
