Description

TECHNICAL FIELD The present invention relates to a moving partitioning device used when partitioning a floor of a hotel, an office, or the like as needed.

[Prior Art] In this type of moving partition device, a ceiling rail having a continuous opening in a bottom wall is fixed to a ceiling of a building, and a plurality of traveling bodies can travel in the ceiling rail. With the placement
Suspension rods are attached to the intermediate portions of these traveling bodies, and the lower ends of the suspension rods are made to pass through the openings and hang down below the ceiling rail. The movable walls are suspended and supported by the pair of suspension rods, and the movable walls can be moved along the ceiling rail.

[Problems to be Solved by the Invention] By the way, a moving wall of this kind can be moved between a use position and a storage position in various modes, and is provided at a portion where ceiling rails intersect. It is not uncommon to select a route and move it. Conventionally, when the ceiling rails are crossed in a state of being orthogonal or close to each other, it is well known that the first traveling wheels are axially attached to the two parallel side surfaces of the traveling body and the other parallel two sides are parallel to each other. The second traveling wheel is pivotally attached to the side surface. Then, in such a device, for example, the vehicle travels by the first traveling wheel to enter the intersection of the ceiling rails, and the second traveling wheel makes a transition from the intersection onto the orthogonal ceiling rail. .

However, in such a structure, since it is necessary to accurately position the traveling body at the center of the intersection and change the traveling direction, the operation is relatively difficult, and skill is required to smoothly move the moving wall. . Further, when the traveling body is located at the intersection, both the first and second traveling wheels are located on 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 in the supported state, it becomes impossible to escape in any direction. Therefore, in order to reliably prevent such an accident, a sophisticated and highly accurate mechanism is required as a traveling body support mechanism provided at the intersection, and there is a problem that manufacture and adjustment are difficult.

Further, with such a structure, it is extremely difficult to allow the moving wall to be self-propelled by a motor or the like, because a delicate operation at the intersection is required.

The present invention aims to solve all such problems.

[Means for Solving the Problems] The present invention adopts the following configurations in order to achieve the above objects.

That is, the moving partition device according to the present invention includes a plurality of ceiling rails, a turntable, a table drive mechanism,
A traveling body, a suspension rod, and a moving wall, wherein a plurality of ceiling rails are horizontally arranged with their ends facing the intersection, and the turntable is the intersection. The table drive mechanism includes a rotating arm disposed adjacent to the turntable and an eccentricity between the tip of the rotating arm and the turntable. The turntable is rotated by about 180 ° from a start point where the pivot arm is substantially aligned with the link member to an end point where the pivot arm is aligned again with the link member. The movable wall is configured to be capable of being driven to turn by a predetermined angle of less than °, and each moving wall is suspended and supported by a ceiling rail via a plurality of traveling bodies and a suspension rod.

The turntable may be of a large size whose movable rail is sized to simultaneously hold a plurality of running bodies supporting each moving wall, or the movable rail may be a single movable rail. It may be a small one sized to hold the traveling body.

When the paired turntables are always operated simultaneously, the eccentric positions of the turntables are connected to each other by the first link member so that the turntables can be rotated synchronously and at the same time, The midway and the tip of the rotating arm may be connected by a second link member.

[Operation] With such a configuration, in the case of a large turntable, after a plurality of traveling bodies supporting the moving wall are supported by the movable rail, on the other hand, in the case of a small turntable, After supporting a single traveling body on its movable rail,
The turning arm of the turntable drive mechanism is turned from the starting point to the 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 the turntable can be guided to the ceiling rail extending in a direction different from the entering direction.

When the rotating arm starts rotating, the tip of the rotating arm moves in a direction orthogonal to the axis of the link member, and when the rotating arm rotates 90 °, the tip of the link member moves. At the stage of moving in the axial direction and rotating by 180 °, the tip again moves in the direction orthogonal to the axial center of the link member. Therefore, even if the rotation speed of the rotation arm is constant, the speed of pulling or pressing the link member in the axial direction gradually increases from zero to reach the maximum speed at the intermediate rotation position, and then gradually increases. It slows down and stops. Therefore, even when the moving wall having a large inertial mass is turned together with the turntable, the turning arm can be reasonably driven by a relatively small power.

In addition, even when a force acts on the rotating arm from the turntable side via the link member when stopped, the force may be a force for rotating the rotating arm. Absent. Therefore, it is not necessary to add a strong lock function to the rotating arm side.

Each moving wall 5 is suspended and supported by two running bodies 6, and the movable rail 22 of the turntable 2 has a length capable of accommodating the two running bodies 6 supporting each moving wall 5 at the same time. Is set to.

Next, the operation of this embodiment will be described. First, when the traveling motor 84 is activated, the rotational power of the traveling motor 84 is transmitted to the rotary sleeve 83 via the reduction gear 89, the drive gear 88 and the driven gear 87, and the sprocket 82 rotates. The sprocket 82, the chain which is fixed to the ceiling rail 1 ₁
81 for which it had been engaged in by the rotation of the sprocket 82, so that the traveling body 6 is self ceiling rail 1 _1.
This makes that the moving wall 5 is moved along the ceiling rail 1 _1. When passing the intersection A on the moving wall 5,
When the two traveling bodies 6 supporting the moving wall 5 are both housed in the movable rail 22 of the turntable 2 (see FIG. 3), the traveling of the moving wall 5 is temporarily stopped. Since the chain 81 is fixedly installed also in the movable rail 22, it is possible to advance the traveling body 5 to a desired position in the movable rail 22. In this state, turn the turntable 2,
Change the direction of the moving wall 5. Specifically, when the motor 34 of the table drive mechanism 3 is operated to rotate the rotating arm 31 from the starting point a to the ending point b, the movable rail 22 connected to the rotating arm 31 via the link rod 35. Turns horizontally and turns 90 °
Change direction (see Figure 4). As a result, the movable rail 22
Ends of the first and _second ceiling rails 1 ₂ and 1 ₃ meet via relay rails 27 ₂ and 27 ₃ . At this stage, turning of the turntable 2 is finished, and the traveling motor 84 is activated again to start traveling of the moving wall 5. Thus, according to this operation, it is possible to change the turn table 2 the direction of the moving wall 5 at once only by turning once, it can be guided to the desired ceiling rail 1 _2, 1 _3.

When the rotating arm 31 starts rotating, the tip of the rotating arm 31 moves in a direction orthogonal to the axis of the link member 35, and at the time of 90 ° rotation, the tip is When the link member 35 is moved in the axial direction and rotated by 180 °, the tip thereof again moves in the direction orthogonal to the axial center of the link member 35. Therefore, even if the rotation speed of the rotation arm 31 is constant, the speed of pulling the link member 35 in the axial direction gradually increases from zero to reach the maximum speed at the intermediate rotation position, and then gradually. It slows down and stops. Therefore, even when the moving wall 5 having a large inertial mass is swung together with the turntable 2, it is possible to drive the rotating arm 31 without difficulty by the relatively small motor 34.

As described above, when the moving wall 5 is moved to the desired position, the traveling motor 84 is stopped, and then the sealing motor 168 is operated to move the upper and lower sealing members 54 and 55 to the ceiling. Press on surface C and floor F. In this embodiment, since the sealing member drive mechanism 160 is held by the floating frame 150, a differential pressing action is performed between the upper close contact member 54 and the lower close contact member 55. The close contact members 54, 55 are pressed against the ceiling surface C and the floor surface F with an equal force.

The operation described above can be automatically performed as appropriate using a normal sequencer or microcomputer. Therefore, each moving wall 5 has a limit switch for detecting whether or not the moving wall 5 is in contact with an adjacent moving wall 5,
Limit switches for detecting whether the upper and lower close contact members 54, 55 are pressed against the ceiling surface C and the floor surface F are provided. Further, the turntable 2 is provided with a sensor for detecting whether or not the traveling body 6 of the moving wall 5 has reached a predetermined position of the movable rail 22, a limit switch for detecting the turning position of the movable rail 22, and the like. deep.

In addition, in the embodiment described above, the case where the turntable is provided at the intersection where the three ceiling rails meet has been described, but a portion where the two ceiling rails intersect and four or more ceiling rails meet. The same applies to intersections.

Further, according to the present invention, not only a large-sized turntable capable of accommodating a plurality of traveling bodies supporting each moving wall at the same time, but also its movable rail is set to a size for holding a single traveling body. The same can be applied to those equipped with a small turntable. In this case, in the case where the paired turntables are always operated simultaneously, the turntables shown in FIGS. 12 and 13 may be used. That is, what is shown in FIG.
The eccentric positions C of the paired turntables 202 are connected to each other by a first link member 236 so that the turntables 202 can be rotated synchronously. That is, this turntable 202 is the turntable 2 described above.
Similarly, the movable rail 222 is rotatably held in the fixed frame 221, and the tip ends of the pedestal portions 222c fixed to the movable rail 222 are connected by the first link member 236. The rotating arm 231 is arranged at an intermediate position between the both turntables 202, and the middle of the link member 236 and the tip of the rotating arm 231 are connected by the second link member 235. .

Even in this case, however, the rotating arm 202 is supported by a gear box (not shown) similar to that of the above-described embodiment, and the power of a motor (not shown) is transmitted to the rotating arm 231 via a reduction gear. To the rotary arm 231
Is rotated about 180 ° from a starting point a which is substantially in line with the link member 235 to an end point b which is again in substantially straight line. The turntables 202 are set so that the turntables 202 can be swiveled by 90 ° by turning. In this embodiment, two parallel ceiling rails 201 ₂ and 202 ₃ that form a storage unit are intersected in a perpendicular manner in a ceiling rail 201, and for example, a turning arm 202 is a starting point. When it is positioned at a, the movable rail 222 of each turntable 202 is set to the first position.
Aligns with ceiling rail 201 ₁ of. In this state, the moving body 206 of the moving wall 205 moved along the ceiling rail 201 ₁
Is guided to the movable rail 222 of each turntable 202, and the rotating arm 202 is rotated to the end point b. As a result, the thirteenth
As shown in the figure, both the movable rails 222 horizontally turn 90 degrees together with the traveling body 206, and the second and third ceiling rails 201 ₂ and 201 ₃
Will be continuous. Therefore, the both traveling body 206 second, it can be led on the third ceiling rail 202 _2, 202 _3, it is possible to move the moving wall 205 in the thickness direction.

EFFECTS OF THE INVENTION Since the present invention has the above-described configuration, the orientation of the traveling body can be forcibly changed at the intersection. Therefore, even if a traveling body having a structure capable of advancing in a certain direction is used, it is possible to change the direction at an intersection at an arbitrary angle and proceed on a desired ceiling rail. Moreover, in that case, there is no need to accurately position the traveling body at the center of the intersection. Therefore, it is possible to smoothly and surely change the direction of the moving wall without providing a highly precise traveling body support mechanism at the intersection, and to make the moving wall a self-propelled type for remote control or automatic driving. It's also relatively easy.

Moreover, even when the rotating arm of the table drive mechanism is rotated at a constant speed, the turning speed of the turntable is mechanically reduced immediately after starting and immediately before stopping. The turntable can be smoothly and smoothly turned with relatively small power. In addition, at the stop position, even if a force acts on the rotating arm from the turntable side, the force does not work in the direction of rotating the rotating arm, so that a large-scale lock mechanism is not necessary. Therefore, the table drive mechanism can be made simple in structure and compact, and can be easily arranged even in a ceiling space where space is limited. In particular, in this structure, the table drive mechanism does not need to be arranged directly above the turntable, but can be arranged on the side of the table, so that the degree of freedom in designing for effective use of space is increased.
