Abstract

PURPOSE:To prevent wheels from falling in by corresponding a pair of pivots with axial centers to arrange to both sides of the central part of a traveller, and loading a plurality of running wheels to both pivots so that they are capable for rotating independently each other. CONSTITUTION:When moving a movable wall, a plurality of running wheels 451 - 456 born to right and left pivots are rolled on rail surfaces 24 formed on both sides of an opening 1. When a traveller 4 comes to a curve, each revolution speed of the running wheels 451 - 456 makes different according to the curvature to move forward smoothly while changing directions. After that, when they move forward along one opening branching off in an acute angle of a rail 2, in a state of rolling some of the running wheels 451 - 456 on the rail surfaces 24, they subsequently pass through the opening. According to the constitution, a smooth movement can be made.

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 continuous opening in the bottom wall.
A rail consisting of a is fixed to the ceiling, and a plurality of running bodies are disposed within this rail so that they can run, and a suspension rod is rotatably attached to the middle part of each of these running bodies, The lower end of the rod is 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 slidable 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] By the way, a conventional running body has running wheels mounted on both ends of a support shaft provided at the front and rear, and these four running wheels are formed on both sides of an opening. It is made to be in contact with the ground rail surface. However, with such a configuration, when the traveling body passes through a branching part of the rail, one of the traveling wheels may fall into the opening, and when the traveling wheel rides on the rail surface again, it may fall into the opening. There is a problem in that large running resistance occurs. In other words, when one of the running wheels passes over the opening at the branching point, the remaining three running wheels will support the load, but due to the influence of centrifugal force, etc., the load will be applied to the point of application of the load. If the vehicle deviates to the outside of the triangular area connecting the three wheels, the vehicle will tilt, and the floating wheels may fall slightly into the opening. If the running wheels sink even slightly into the opening, if the moving wall is heavy, a large amount of force will be required for the running wheels to ride on the rail surface, making smooth movement difficult. There's a problem.

In addition, if the running wheels are spaced apart from each other in the front and back, when the running body approaches a curve and moves while changing its direction of travel, side slipping may occur between each running wheel and the rail surface. The increase in running resistance due to sideslip cannot be ignored.

The present invention aims to solve the above problems.

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

That is, the movable partition device according to the present invention includes a rail fixed to the ceiling and having a continuous opening in the bottom wall;
A running body is disposed within the rail and can run with its intermediate portion facing the opening, and a running body is rotatably attached to the intermediate portion of each of these running bodies and its lower end is suspended below the rail through the opening. A movable partition device comprising a pair of suspension rods and a movable wall suspended and supported by a pair of suspension rods, wherein each of the traveling bodies is arranged in pairs on both sides of a central portion of the main body. It is characterized in that the support shafts are arranged with their axes aligned with each other, and a plurality of running wheels are mounted on both support shafts so as to be able to rotate independently of each other.

[Operation] With this kind of configuration, when moving the movable wall, a plurality of running wheels supported by left and right support shafts roll on rail surfaces formed on both sides of the opening. This causes each traveling body to travel along the rail. In this case, when each traveling body approaches a curve, the rotational speed of each traveling wheel becomes different depending on the curvature.
The traveling body can move forward while changing direction smoothly. Therefore, side slip between the running wheels and the rail surface is suppressed to a minimum.

When the traveling body travels along one opening that branches at an acute angle at a branching portion of the rail, the traveling wheels attached to one of the support shafts diagonally cross the other opening. At this time, if multiple running wheels are attached to one support shaft, the settings should be made so that each running wheel can pass through the opening in sequence while any of the running wheels is moving on the rail surface. It becomes possible to do so. Therefore, it is possible to reliably eliminate the problem of the traveling wheels falling into the opening.

[Example code] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, this movable partition device has a rail 2 having a continuous opening 1 in the bottom wall fixed to the ceiling 3, and a plurality of running rails inside the rail 2. The bodies 4 are disposed in a movable manner, and suspension rods 5 are rotatably attached to the intermediate portions of each of these traveling bodies 4, and the lower ends of the suspension rods 5 are inserted below the rail 2 through the opening 1. It is hanging down. A movable wall 6 is suspended and supported by a pair of suspension rods 5, respectively, so that the movable wall 6 can be moved along the rail 2.

As shown in FIGS. 2 and 3, the rail 2 includes a straight portion 21 and a branched portion 22. The straight part 21 is
A linear opening 1 is provided at the center of the bottom wall 23, and rail surfaces 24 are formed on both sides of the opening 1. The branch portion 22 has a linear opening 11 in the bottom wall 23, for example.
and an opening 1□ that branches off from the opening 11 at an acute angle, and rail surfaces 24 are formed on both sides of each of the openings L and 12.

As shown in FIGS. 4 and 5, the traveling body 4 includes a main body 42 having a stepped through hole 41 in the center for penetrating and holding the suspension rod 5. The upper end flange 51 of the suspension rod 5 is rotatably and tiltably supported by a spherical seat 43 provided on a step 41 via a thrust bearing 52. A pair of support shafts 44 are provided on both sides of the center of the main body 42, with their axes aligned with each other, and a plurality of running wheels 45, 453 (454-456) are mounted on each of these support shafts 44, respectively. ing. That is, the support shafts 44 are installed between the center wall 46 of the main body 4 into which the through hole 41 is nailed, and the side walls 47 arranged oppositely on both sides thereof, and three running wheels 451 are installed on each support shaft 44. ~453 (45
4 to 456) are supported so as to be able to rotate independently. Running wheels 45. -456 are made of metal and have a bearing structure.

In addition, 48 is a guide roller for straight running which is pivoted on both the front and rear edges of the main body 42, and 49 is a guide roller for path selection. The guide roller 49 for path selection is guided by a guide member 26 fixed to the top wall 25 of the rail 2, and the guide member 26 is designed to guide the traveling body 4 to a predetermined route. be. In this example,
At a branching portion 22 of the rail 2 shown in FIG. 3, a specific traveling body 4 is guided by a guide member 26 to the branched opening 12 side.

With such a configuration, when moving the movable wall 6, the three running wheels 451 to 456 supported on the left and right support shafts 44 move on the rail surfaces formed on both sides of the opening 1. By rolling on the rail 24, each running body 4
will be traveling along. In this case, when each traveling body 4 approaches a curve, each traveling wheel 4
The rotational speeds of 51 to 456 are different from each other,
The traveling body 4 can proceed while changing direction smoothly. Therefore, side slip between the running wheels 45, 456 and the rail surface 24 is suppressed to a minimum. Therefore, an increase in running resistance due to sideslip can be effectively suppressed.

When the traveling body 4 travels along one opening 12 that branches at an acute angle at the branching portion 22 of the rail 2,
Running wheels 454 to 456 attached to one support shaft 44 diagonally cross the other opening 1. At this time, if a plurality of running wheels 454 to 456 are attached to one of the support shafts 44, each of the running wheels 454 to 456 is rolling on the rail surface 24. 4
56 can be set so that they can pass through the opening 1 in sequence. Therefore, it is possible to reliably eliminate the problem that the running wheels 451 to 453 fall into the opening 1. A detailed explanation based on FIG. 3 is as follows. First, position a shown in FIG. 3 shows a state in which the traveling body 4 is traveling on a straight section 21. At this time, all the running wheels 45 to 456 are in rolling contact with the rail surface 24. At position b and position C, the traveling body 4 is at the branching part 2.
2 and shows the process in which the running wheels 454 to 456 pass through the opening 11. When the traveling body 4 starts turning, the inner traveling wheels 454 first close the opening 1. It passes above the object in a floating state and reaches point b. In this process, the other running wheels 456, 456 are in rolling contact with the rail surface 24 (the shaded area along the center line is the running wheel 456).
51 to 456 are in rolling contact with the rail surface 24), the traveling wheels 454 to 456 passing through the opening 11 do not fall into the opening 1. As the traveling body 4 further advances from position b toward position C, the inner traveling wheel 454 that has passed through the opening 1 comes into rolling contact with the rail surface 24, so that the intermediate traveling wheel 455 and the outer traveling wheel 454 The running wheels 456 of the vehicle also pass through the opening 11 one after another without falling into the opening 1. Position C indicates the moment when the outer running wheel 456 begins to pass through the opening 1. In this way, the main running body 4
Even when passing through the branching portion 22, none of the running wheels 45□ to 456 fall into the opening 1. Therefore, there is no possibility that the running wheels 45, to 456 may fall into the opening 1 and then ride on the rail surface 24 again, and the movable wall 6 can be moved easily and smoothly.

Note that the form of the rail is not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention.

Furthermore, the number of running wheels mounted on each support shaft is not limited to three.

[Effects of the Invention] Since the present invention has the above-described configuration, it is possible to avoid problems such as when a traveling body passes through a branch part, the wheels of the vehicle fall into the opening, causing an impact and an increase in running resistance. , it is possible to effectively solve the problem of increased running resistance due to side slip between the running wheels and the rail surface when the running body changes course, and it can always move the moving wall to the rail easily and smoothly. It is possible to provide a movable partition device that can be moved along.
