Description

TECHNICAL FIELD The present invention relates to a moving partitioning device used for partitioning a floor of a hotel, a hofis 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 includes, for example, an operating shaft having two types of screw parts that are reverse screws to each other, a pair of nuts screwed to the screw parts of the operating shaft, and a link member. And a four-point link in which the left and right pivot points are pivotally attached to the nuts, and the upper and lower pivot points and the upper and lower points of the four-point link. The close contact member is connected by an elevating 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, an upper / lower contact member, upper / lower lifting shafts, and a lifting arm. A shaft drive mechanism, wherein the moving wall is suspended and supported by the ceiling rail so as to be movable via the suspension rod and the traveling body, and the upper and lower contact members. Are arranged 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 hold the upper and lower contact members at their tips. The lift shaft drive mechanism is arranged so as to be able to move up and down in the moving wall, and the lift shaft drive mechanism has a substantially horizontal operation shaft, a rotary cylinder fixed to the operation shaft with its axis orthogonal to each other, and both ends. And a rotating arm slidably held in the rotating cylinder by projecting the Serial operation shaft penetrates the rotary sleeve,
The rotating arm is provided with a long hole for avoiding interference with the operation shaft. The upper and lower elevating shafts are pivotally attached to one end of the rotating arm and the lower elevating and lowering shaft is pivotally attached to the other end. The pivotable range of the pivot arm is restricted from a standby position where the upper and lower close contact members are retracted to a lock position where the upper and lower close contact members have slightly passed the position where the upper and lower close contact members protrude most. Characterize.

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

In order to simplify the manufacturing, the rotating arm may be made flat by plastically deforming both ends of the metal pipe material,
It is recommended to use synthetic resin. In order to suppress or cancel the influence of gravity, the lower lifting shaft may be biased upward by a spring.

[Operation] According to the moving partition device having such a configuration, when the rotating arm is held at the standby position, the lower and upper contact members are recessed in the moving wall. From this state, when the operation shaft is rotated to rotate the rotation cylinder in the lock position direction, the rotation arm is also urged by the rotation cylinder and the rotation arm also rotates. The upper and lower lifting shafts pivotally attached are pressed in a direction in which the upper and lower contact members project. As a result, the upper and lower close contact members are pressed against the ceiling surface and the floor surface, respectively. When the upper and lower contact members slightly pass through the most projecting position and are locked at the lock position, the rotating arm is stably held at the lock position by the principle of the toggle mechanism. Therefore, even when the operation of the operation shaft is stopped, the upper and lower contact members are kept pressed against the ceiling surface and the floor surface.

The rotating arm can slide in the axial direction of the rotating cylinder fixed to the operation shaft. Therefore, in the vicinity of the lock position, this rotating arm can move substantially vertically, and the upper contact member and the lower contact member are always the same force if the influence of gravity is neglected. It will be pressed against the surface. Further, the rotation arm is provided with a long hole for avoiding interference with the operation shaft, and the operation shaft is fixed to the rotation cylinder through the long hole, so that the rotation cylinder is securely attached to the operation shaft. The operation shaft can be supported, and if necessary, bearings can be arranged at both ends of the operation shaft to support the operation shaft in a two-sided manner.

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 81
Is rotated manually or electrically, the rotational movement is transmitted to the rotary cylinder 82, and the rotary arm 83 held by the rotary cylinder 82 moves from the standby position shown in FIG. It rotates to the lock position side shown in the figure. At that time, the upper and lower lifting shafts 6,
If the loads acting on 7 are the same, the rotating arm 83 rotates about the axis of the operation shaft 81. As a result, the upper and lower elevating shafts 6 and 7 move at the same speed in the protruding direction by the same dimension. When one of the upper and lower contact members 54, 55 first comes into contact with the ceiling surface C or the floor surface F, the protruding operation of the one contact member 54 (55) stops and the ceiling surface By the reaction from C or the floor surface F, the rotating arm 83 moves downward or upward in the rotating cylinder 82 via the one close member 54 (55) and the upper and lower lifting shafts 6 and 7. The other close member 55 (54)
The projecting motion of is accelerated. And both close members 54,
After 55 comes into contact with the ceiling surface C and the floor surface F, the operation is further continued, and the upper and lower contact members 54, 55 are pivoted to a lock position (see FIG. 6) slightly past the position where they are most protruded. When the arm 83 is rotated, the rotating arm 83 is stably held at the lock position by the principle of the toggle mechanism, and the upper and lower contact members 54, 55 are evenly forceed by the ceiling surface C and the floor surface. Pressed on F. Therefore, even when the operation of the operation shaft 81 is stopped, the pressing state of the close contact members 54, 55 against the ceiling surface C and the floor surface F is maintained. The spring 75 suppresses or cancels the downward urging of the lower elevating shaft 7 due to gravity, but if the influence of gravity remains, the operation shaft 81 is rotated. When operated, the rotating arm 83 moves downward in the rotating cylinder 82 near the lock position of the rotating arm 83. Then, when the lower contact member 55 comes into contact with the floor surface F, the upper elevating shaft 6 starts to project upward again again, and finally, the both contact members 54, 55 are substantially even. It is possible to press against the ceiling surface C and the floor surface F.

Needless to say, the close contact member is not limited to that of the embodiment described above. For example, as shown in FIG.
The shield plate portion 254a ₁ on the one surface side and the shield plate portion 254a ₂ on the other surface side are
The close contact member 254 may be integrally connected via the horizontal flat plate portion 254b.

Furthermore, the moving wall may be driven by a motor so as to be able to move by itself.

EFFECTS OF THE INVENTION Since the present invention has the above-described configuration, the rotary motion applied to the operation shaft is transmitted to the upper and lower lift shafts via the rotary arm that is slidable in the vertical direction. The upper and lower close contact members held by the respective elevating shafts can be pushed and retracted. 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. In particular, according to the present invention, the rotary arm is provided with a long hole for avoiding interference with the operation shaft, and the operation shaft is fixed to the rotary cylinder through the long hole. The rotary cylinder can be securely fixed to the operation shaft without disturbing the operation shaft, and in some cases, it is possible to dispose bearings at both ends of the operation shaft and support them both-sidedly. Therefore, it is possible to securely hold the rotating arm to which a comparatively large load is applied via the rotating cylinder, and to allow the rotating arm to freely slide in that state, which results in a high sound insulation characteristic of the partitioning device. It is possible to exert the excellent light-shielding property and the high light-shielding property.
