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 ceiling rail with a continuous opening in the bottom wall fixed to the ceiling of a building, and allows multiple running bodies to run within the ceiling rail. In addition to arranging
A suspension rod is attached to the intermediate portion of each of these traveling bodies, and the lower ends of the suspension rods are passed through the opening and suspended below the ceiling rail. The movable wall is suspended and supported by the pair of suspension rods, respectively, so that the movable wall can be moved along the ceiling rail.

[Problems to be Solved by the Invention] By the way, this type of movable wall can be moved in various ways between the use position and the storage position, and it is possible to move the movable wall in various ways between the use position and the storage position. It is not uncommon to select a route to move. Conventionally, when ceiling rails are crossed orthogonally or nearly so, as is well known, a first running wheel is pivoted on two parallel sides of a running body, and the other two parallel sides are A second running wheel is pivotally attached to the side surface. Thus, in such a device, for example, the first running wheel is used to travel and enter an intersection of ceiling rails, and the second running wheel is used to move from the intersection onto a perpendicular ceiling rail. .

However, with this type of configuration, it is necessary to accurately position the moving body at the center of the intersection and change the direction of travel, which is relatively difficult to operate and requires skill to move the moving wall smoothly. . Furthermore, when such a traveling body is located at an intersection, both the first and second traveling wheels are located above the opening of the ceiling rail and are in a floating state.
It is necessary to support the traveling body by a special mechanism provided separately, but if the traveling body rotates while being supported, it will be impossible to escape in any direction. Therefore, in order to reliably prevent such accidents, a sophisticated and highly accurate mechanism is required as a traveling body support mechanism installed at an intersection, which poses the problem of being difficult to manufacture and adjust.

Furthermore, with such a structure, it is extremely difficult to make the movable wall self-propelled by a motor or the like, since delicate operations are required at intersections.

The present invention aims to solve all of these problems.

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

That is, the movable partition device according to the present invention includes a plurality of ceiling rails, a turntable, a table drive mechanism,
It is equipped with a traveling body, a suspension rod, and a movable wall, the plurality of ceiling rails are arranged horizontally with their ends facing the intersection, and the turntable is arranged horizontally with the end facing the intersection. It is equipped with a movable rail that has the same cross-sectional shape as the ceiling rail, and the table drive mechanism consists of a rotating arm placed adjacent to the turntable, and an eccentric connection between the tip of this rotating arm and the turntable. and a link member that connects the rotary arm with the link member, and the turntable rotates by approximately 1806 degrees from a starting point where the rotating arm is substantially in line with the link member to an end point where the rotating arm is again approximately in a straight line. Each movable wall is configured to be able to rotate by a predetermined angle, and each movable wall is suspended and supported from a ceiling rail via a plurality of traveling bodies and suspension rods.

The turntable may be large in size, with its movable rails sized to simultaneously hold multiple running bodies that support each moving wall, or its movable rails may be large enough to simultaneously hold multiple running bodies that support each moving wall, or may be large enough to support a single moving rail. It may be a small size set to hold a traveling body.

When a pair of turntables are always operated simultaneously, the eccentric positions of the turntables are connected by a first link member so that the turntables can rotate in synchronization. The intermediate portion and the tip of the rotating arm may be connected by a second link member.

[Function] With such a configuration, in the case of a large turntable, after the plurality of running bodies supporting the movable wall are supported on the movable rail, in the case of a small turntable, After supporting a single traveling body on its movable rail,
A rotating arm of a turntable drive mechanism is rotated from a starting point to an ending point. As a result, the rotation is transmitted to the turntable via the link member, and the turntable turns by a predetermined angle. Therefore, the traveling body supported by the movable rail of this turntable can be guided to the ceiling rail extending in a direction different from the direction of entry.

Note that when the rotating arm starts rotating, the tip of the rotating arm moves in a direction perpendicular to the axis of the link member, and when it has rotated 90 degrees, the tip of the rotating arm moves in the direction perpendicular to the axis of the link member. When the tip moves in the axial direction and rotates 180 degrees, the tip moves again in a direction perpendicular to the axis of the link member. Therefore, even if the rotation speed of the rotation arm is constant, the speed at which the link member is pulled or pushed in the axial direction gradually increases from zero, reaches the maximum speed at the intermediate rotation position, and then gradually decelerates. and comes to a halt. Therefore, even when a movable wall with a large inertial mass is rotated together with the turntable, it is possible to easily drive the rotating arm with a relatively small power.

In addition, even if a force is applied to the rotating arm from the turntable side through the link member when it is stopped, that force may not become the force that causes the rotating arm to rotate. do not have. Therefore, there is no need to provide a strong locking function to the rotating arm side.

Each movable wall 5 is suspended and supported by two traveling bodies 6, and the movable rail 22 of the turntable 2 has a length that can simultaneously accommodate the two traveling bodies 6 that support each movable wall 5. It is set to .

Next, the operation of this embodiment will be explained. First, when the traveling motor 84 is started, the rotational power of the traveling motor 84 is transmitted to the rotating sleeve 83 via eight reduction gears, the driving gear 88, and the driven gear 87, and the sprocket 82 is rotated. Since this sprocket 82 is meshed with a chain 81 fixedly installed on the ceiling rail 11, the rotation of the sprocket 82 causes the traveling body 6 to run on its own within the ceiling rail 1□. This causes the movable wall 5 to move along the ceiling rail 1. When the movable wall 5 is caused to pass through the intersection A, when the two traveling bodies 6 supporting the movable wall 5 are both stored in the movable rail 22 of the turntable 2 (see FIG. 3), the movable wall 5 is moved. The movement of the wall 5 is temporarily stopped.

Since the chain 81 is also fixed inside the movable rail 22, it is possible to advance the traveling body 5 to a desired position within the movable rail 22. In this state, the turntable 2 is rotated to change the direction of the movable wall 5. in particular,
When the motor 34 of the table drive mechanism 3 is activated to rotate the rotating arm 31 from the starting point a to the ending point, the movable rail 22 connected to the rotating arm 31 via the link rod 35 rotates horizontally. Change direction by 90 degrees (see Figure 4). As a result, the end of the movable rail 22 is connected to the end of the second and third ceiling rails 1□, 13 by the relay rails 27□, 273.
Match via. At this stage, the turn of the turntable 2 is completed, and the travel motor 84 is started again to start the travel of the movable wall 5.

According to this operation, the direction of the movable wall 5 can be changed all at once by rotating the turntable 2 once, and the movable wall 5 can be guided to a desired ceiling rail 1□, 13.

Note that when the rotating arm 31 starts rotating, the tip of the rotating arm 31 moves in a direction perpendicular to the axis of the link member 35, and when it rotates 90 degrees, the tip of the rotating arm 31 moves in a direction perpendicular to the axis of the link member 35. When the link member 35 moves in the axial direction and rotates 180', the tip thereof moves in a direction perpendicular to the axial center of the link member 35 again. Therefore, even if the rotational speed of the rotational arm 31 is constant, the speed at which the link member 35 is pulled in the axial direction gradually increases from zero, reaches the maximum speed at the intermediate rotational position, and then gradually increases. It slows down and comes to a stop. Therefore, the moving wall 5 with a large inertial mass
Even when rotating together with the turntable 2,
The relatively small motor 34 allows the rotating arm 31 to be driven easily.

When the movable wall 5 has been moved to the desired position as described above, the traveling motor 84 is stopped, and the sealing motor 168 is activated to move the upper and lower sealing members 54.
55 against the ceiling C and floor F. In this embodiment, the sealing member drive mechanism 160 is connected to the floating frame 1.
50, a differential pressing action is performed between the upper writing contact member 54 and the lower writing contact member 55, and these peripheral contact members 54 and 55 press against the ceiling surface C and the floor with equal force. It is pressed against surface F.

The operations described above can be automatically performed as appropriate using an ordinary sequencer or microcomputer. For this purpose, each movable wall 5 is equipped with a limit switch for detecting whether or not it has come into contact with an adjacent movable wall 5, and upper and lower contact members 54 and 55 are pressed against the ceiling C and floor F. A limit switch is provided to detect whether or not the Further, the turntable 2 is provided with a sensor that detects whether the traveling body 6 of the movable wall 5 has entered a predetermined position of the movable rail 22, a limit switch that detects the turning position of the movable rail 22, etc. put.

In addition, in the embodiment described above, a case was explained in which a turntable is provided at an intersection where three ceiling rails meet, but it can also be used at an intersection where two ceiling rails intersect or where four or more ceiling rails meet. It can be similarly applied to intersections.

Furthermore, the present invention provides not only a large turntable capable of simultaneously accommodating a plurality of moving bodies that support each movable wall, but also a turntable whose movable rails are sized to hold a single running body. It can be similarly applied to a device equipped with a small turntable.

In this case, if the paired turntables are always operated simultaneously, the arrangement shown in FIGS. 12 and 13 may be used. That is, in the case shown in FIG. 12, the eccentric positions C of the pair of turntables 202 are connected by the first link member 236, and the turntables 20
2 are constructed so that they can rotate synchronously. That is, like the turntable 2, this turntable 202 has a movable rail 222 rotatably held within a fixed frame 221, and the tips of the pedestal portion 222C fixed to the movable rail 222 are connected to each other. They are connected by a first link member 236.

The rotating arm 231 is disposed at an intermediate position between both turntables 202, and the middle of this link member 236 and the tip of the rotating arm 231 are connected by a second link member 235. .

In this case as well, the rotating arm 202 is supported by a gear box (not shown) similar to that of the above embodiment, and power from a motor (not shown) is transmitted to the rotating arm 231 via a speed reducer. By transmitting the information to
I'm trying to rotate it. And this rotating arm 2
By the rotation of 31, each turntable 202 rotates 9
It is set so that it can be rotated by 0''.The problem with this embodiment is that the storage section is configured in the ceiling rail 201.
This is a case where the parallel ceiling rails 2012 and 2023 of the book are crossed in an orthogonal state, for example, the rotating arm 20
2 is located at the starting point a, the movable rail 222 of each turntable 202 is connected to the first ceiling rail 201.
It matches 1. In this state, the traveling body 206 of the movable wall 205 that has been moved along the ceiling rail 2011 is guided onto the movable rail 222 of each turntable 202, and the rotating arm 202 is rotated to the end point. the result,
As shown in FIG. 13, both movable rails 222 horizontally turn by 90'' together with the traveling body 206, and are connected to the second and third ceiling rails 2012 and 2013. 2. Third ceiling rail 20
22.2023, and the movable wall 205 can be moved in the thickness direction.

[Effects of the Invention] Since the present invention has the above configuration, the direction of the traveling object can be forcibly changed at an intersection. Therefore, even if a vehicle configured to travel in a fixed direction is used, it is possible to change direction at an intersection by an arbitrary angle and make the vehicle travel onto a desired ceiling rail.

Moreover, in this case, there is no need to accurately position the traveling body at the center of the intersection. Therefore, the direction of the moving wall can be changed smoothly and reliably without installing a highly accurate traveling body support mechanism at the intersection. It will also be relatively easy.

Furthermore, even if the rotating arm of the table drive mechanism is rotated at a constant speed, the rotating speed of the turntable is mechanically reduced immediately after starting and immediately before stopping. , the turntable can be rotated easily and smoothly with a relatively small amount of power. Moreover, in the stop position, even if a force is applied to the rotating arm from the turntable side, the force does not act in a direction to rotate the rotating arm, so a large-scale locking mechanism is not required. Therefore, the table drive mechanism can be made simple and compact in structure, and can be easily placed in the ceiling where space is limited. In particular, in this case, the table drive mechanism does not need to be placed directly above the turntable, but can be placed on the side thereof, so the degree of freedom in design is increased in terms of effective use of space.
