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. When partitioning the floor with such moving walls, these moving walls are arranged in a line along the ceiling rail, and both ends in the width direction are brought into close contact with each other. Further, in order to close the gap between the upper edge of the moving wall and the ceiling surface and the gap between the lower edge of the moving wall and the floor surface, which are required during movement, The upper and lower contact members are projected so as to be in close contact with the corresponding ceiling surface and floor surface, respectively.

The upper and lower close contact members are internally mounted on the moving wall and are held by the lower lift shafts. The lift shafts are moved up and down by the lift shaft drive mechanism to perform a projecting and retracting operation. A conventional lifting shaft drive mechanism has an operating shaft having two types of screw parts which are mutually reverse screws, a pair of nuts screwed into the screw parts of the operating shaft, and a link member having a rhombus shape. And a four-point link in which the left and right pivot points are pivotally attached to the nuts. The upper and lower pivot points of the four-point link and the upper and lower contact members. And are connected by a lifting shaft. The operation shaft is supported by the frame of the moving wall.

[Problems to be Solved by the Invention] With such a configuration, by rotating the operation shaft via a detachable handle or the like, a nut screwed into both screw portions of the operation shaft is provided. When the four-point links are moved in the direction toward each other, the left and right pivot points of the four-point link approach each other, and the upper and lower pivot points perform a separating operation. As a result, above,
The lower elevating shaft moves in a separating direction, the upper contact member is pressed against the ceiling surface, and the lower contact member is brought into close contact with the floor surface. An elastic expansion / contraction part is provided in the middle of each elevating shaft so that each elevating shaft can be elastically contracted when the upper and lower contact members are pressed against the ceiling surface and the floor surface. There is.

However, in the case of only this, when the upper clearance and the lower clearance are different, the elastic expansion / contraction portions provided in the middle of the respective elevating shafts have different expansion / contraction degrees.
Therefore, when the dimensional difference between the upper gap and the lower gap is large, it is difficult to sufficiently absorb the difference only by the elastic action of the elastic elastic portion. As a result, a large difference may occur in the pressing force of the upper and lower close contact members, and in an extreme case, for example, the upper close contact member is firmly pressed against the ceiling surface, but the lower close contact member is It may lead to the situation that it is not completely pressed against the floor. Therefore, there is a problem that sound insulation and light shielding performance are deteriorated.

The present invention aims to solve 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 ceiling rail, a traveling body, a suspension rod, a moving wall, upper and lower contact members, an upper and lower lifting shaft, and a differential gear type lifting shaft.

The lower contact member is disposed at the upper edge and the lower edge of the moving wall so as to project and retract toward the ceiling surface and the floor surface, and both the elevating shafts have a threaded portion at the base end. At the same time, the upper and lower contact members are respectively held at their tips and are arranged to be able to move up and down in the moving wall, and the lifting shaft drive mechanism is a pair of bevel gears with their axes aligned. , The upper and lower feed nuts that rotate with each of these bevel gears respectively, A retainer rotatably arranged outside the bevel gear, and a planetary gear that is rotatably attached to the retainer and meshes with the bevel gears. It is characterized in that it can be converted into rotation of the retainer, and the screw portion of the elevating shaft is screwed forward and backward by the rotation of each of the feed nuts.

The operation shaft may be configured to be electrically rotatable and manually configured to be rotatable.

In order to reduce the number of parts and simplify the structure, it is preferable that the bevel gear is provided with a boss portion and a female screw is engraved on the inner circumference of the boss portion to form the feed nut.

[Operation] According to the moving partition device having such a configuration, when the operation shaft is rotationally operated, the rotational motion is transmitted to the retainer, and the planetary gears held by the retainer revolve. that time,
When the loads acting on the upper and lower lifting shafts are the same, the planetary gears do not rotate, and the bevel gears forming a pair rotate at the same speed. As a result, the upper and lower feed nuts rotate at the same speed, and the upper and lower lifting shafts screwed onto the nuts move in the protruding direction at the same speed.
Then, when one of the upper and lower contact members first comes into contact with the ceiling surface or the floor surface, the protruding operation of the one contact member is stopped, and the planetary gear rotates in addition to the revolution, The protruding operation of the other lifting shaft is accelerated. Then, when both the close contact members come into contact with the ceiling surface and the floor surface, when the operation is further continued, the upper and lower close contact members are evenly rotated by the appropriate revolution and rotation of the planetary gears, so that the upper and lower close contact members have equal force. It is pressed against the surface.

The suspension rod 4 is introduced into the moving wall 5 through the hollow center portion of the shaft.

Next, the operation of this embodiment will be described.

FIG. 1 and FIG. 4 show a state in which the upper and lower close contact members are immersed. In this state, an upper gap is formed between the moving wall 5 and the ceiling surface C, and a lower gap is formed between the moving wall 5 and the floor surface F, so that the moving wall 5 is attached to the ceiling rail 1. It becomes possible to move along.

After moving the moving wall 5 to a desired position, the operation shaft 87
Is rotated manually or electrically, the rotational movement is transmitted to the retainer 85 via the small bevel gear 90 and the large bevel gear 89, and the planetary gear 86 held by the retainer 85 revolves. At that time, if the loads acting on the upper and lower lifting shafts 6 and 7 are the same, the planetary gear 86 is
Does not rotate and paired bevel gears 81 and 82 rotate at the same speed. As a result, the upper and lower feed nuts 83, 84 rotate at the same speed, and the upper and lower lift shafts 6, 7 screwed onto the nuts 83, 84 move in the protruding direction at the same speed. (See FIG. 6). When one of the upper and lower contact members 54, 55 comes into contact with the ceiling surface C or the floor surface F first,
The projecting operation of one of the close contact members 54 (55) is stopped, and the planetary gear 86 rotates in addition to the revolution, and the other close contact member 54
The projecting motion of 55 (54) is accelerated. Then, when both the close contact members 54, 55 are in contact with the ceiling surface C and the floor surface F and the operation is further continued, the upper and lower close contact members 54, 55 are made uniform by the proper revolution and rotation of the planetary gear 86. Ceiling surface C
And is pressed against the floor surface F. In addition, in the case of this embodiment, since both the elevating shafts 6 and 7 are urged downward by gravity, the force required to project the upper elevating shaft 6 is lower. It is larger than the force required to project 7 downward. for that reason,
When the operating shaft 87 is rotationally operated, the planetary gear 86 revolves from the beginning, and first, the lower lifting shaft 7 projects downward.
Then, when the lower contact member 55 comes into contact with the floor surface F and the force required to project the lifting shaft 7 increases,
The upper elevating shaft 6 starts to project upward, and finally it becomes possible to evenly press both the close contact members 54, 55 against the ceiling surface C and the floor surface F.

The close contact member is of course not limited to that of the embodiment described above, and for example, as shown in FIG.
The shield plate portion 154a ₁ on the one surface side and the shield plate portion 154a ₂ on the other surface side are
It may be integrally connected via the horizontal plate portion 154b.

Further, the moving wall may be configured to be driven by a motor so as to be self-propelled.

Furthermore, it goes without saying that the elevating shaft may be urged upward by a spring to cancel the influence of gravity.

EFFECTS OF THE INVENTION Since the present invention has the above-described configuration, the rotational motion applied to the operating shaft is differentially distributed and transmitted to the upper and lower lifting shafts, and the upper and lower shafts are held by these lifting shafts. The lower contact member can be moved in and out. Therefore, even when the upper gap and the lower gap are set to different values, the upper and lower close contact members can be pressed against the ceiling surface and the floor surface evenly and reasonably. Therefore, there is an effect that the sound insulation performance and the light shielding performance can be maintained at high values.
