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.

Such upper and lower close contact members are made to project and retract by a close contact member drive mechanism installed inside the moving wall.
In the conventional close contact member drive mechanism, 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 are diamond-shaped. 4 and the left and right pivot points are pivotally attached to each nut.

[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, if this is the only end, if there is a relatively large difference between the gap from the upper edge of the moving wall to the ceiling surface and the gap from the lower edge of the moving wall to the floor surface, then the upper contact member The pressing force to the ceiling surface of and the pressing force to the floor surface of the lower contact member may differ greatly,
There is a problem that the sound insulation performance and the light shielding performance are adversely affected.

Further, with such a configuration, there are problems that the structure inside the moving wall becomes complicated due to the large number of parts, the manufacturing and adjustment are troublesome, and it is difficult to reduce the weight of the moving wall.

The present invention aims to solve such problems.

[Means for Solving the Problems] In order to achieve the above-mentioned objects, the present invention may employ the following configurations.

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 close contact members, upper and lower lift shafts, and a shape memory alloy expandable member. And a temperature control means, wherein the ceiling rail has a continuous opening on the lower surface,
The traveling body is disposed so as to be capable of traveling in the ceiling rail, and the suspension rod is held by the traveling body, and a lower end side thereof is hung downward from an opening portion of the ceiling rail. The moving wall is suspended and supported movably on the ceiling rail through the suspension rod and the traveling body, and the upper and lower contact members are provided on the upper edge portion and the lower edge portion of the moving wall, Arranged so as to be able to project and retract toward the ceiling surface and the floor surface, the both elevating shafts are arranged so as to be able to ascend and descend in the moving wall with their base ends facing each other, and at each tip, the above, The lower contact member is held, the elastic member is interposed between the both elevating shafts, and the temperature control means is arranged at a position that does not prevent the elastic member from expanding and contracting and moving up and down. It is characterized in that it is configured to be able to change the temperature of.

When importance is placed on the simplification of the structure, it is preferable that a heater is used as the temperature control means and the temperature of the elastic member can be changed by selecting whether to energize or de-energize the heater.

In particular, in order to reduce the number of parts, a so-called bidirectional shape memory alloy is used as the elastic member, and the shape memory alloy is made to store the position at room temperature and the position at the heating temperature by the heater, respectively. It's good to leave.

When a unidirectional shape memory alloy is used as the elastic member, only the position at the heating temperature of the heater is stored in the shape memory alloy, and when the power to the heater is cut off, a separate The expansion / contraction position of the expansion / contraction member is changed to a position different from the storage position by a mechanical spring provided in the.

The temperature control means is not limited to the heater but may be a cooling device. In that case, the temperature of the expansion / contraction member is changed by selecting energization and de-energization to the cooling device, and the expansion / contraction member is provided with a position at room temperature and a position at the cooling temperature by the cooling device. Remember each. Alternatively,
In the expansion and contraction member, only the position at the cooling temperature by the cooling device is stored, and when the cooling device is de-energized, a mechanical spring that is separately provided at a different position from the storage position, The expansion / contraction position of the expansion / contraction member may be changed.

[Operation] With such a configuration, the temperature control means can change the temperature of the shape-memory alloy expansion / contraction member to expand / contract the expansion / contraction member between the contracted position and the expanded position. Then, when this elastic member is shrinking,
The upper and lower elevating shafts are pulled toward each other, and the upper and lower contact members are held in the retracted position. On the other hand, when the elastic member is extended, the upper elevating shaft is pressed upward and the lower elevating shaft is pressed downward, and the upper contact member is protruded upward and pressed against the ceiling surface, and the lower contact member is pressed downward. The member projects downward and is brought into close contact with the floor surface. At this time, since the elastic member can freely move up and down, the upper contact member and the lower contact member are pressed against the ceiling surface and the floor surface with relatively equal force.

Inside the 73, a heater 109 as a temperature control means is provided. The elastic member 109 is formed by molding a wire made of a one-way shape memory alloy on a coil.
Only the position at the heating temperature according to is stored. This storage position is set to a position where the elastic member 108 is slightly extended from the state shown in FIG. 7, that is, the state in which the upper and lower close contact members (not shown) are immersed in the moving wall 5. . With such a configuration, when the heater 109 is energized to heat the expansion / contraction member 108, the expansion / contraction member 108 is directed to the storage position against the mechanical biasing force of the spring 185. The upper and lower lifting shafts 6,
7 are pulled toward each other, and the upper and lower close contact members are moving walls 5
Immerse yourself in. On the other hand, when the heater 108 is de-energized, the extension force of the elastic member 108 is deenergized, so that the upper and lower lifting shafts 6 and 7 are mechanically repulsive to the spring 185, as shown in FIG. Is urged in the direction of separating by
The lower contact member projects and is pressed against the ceiling surface and the floor surface.

Further, the temperature control means is not limited to the one described above, and for example, a heater may be provided in contact with the elastic member, or a cooling device may be used instead of the heater. As a cooling device that can be suitably used in such a place, a device using a semiconductor that performs a so-called electronic cooling action can be cited.

Furthermore, the close contact member is not limited to that of the embodiment described above, and for example, as shown in FIG. 9, one side shield plate portion 154a ₁ and the other side shield plate portion 154a _{2 are provided.} And 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.

EFFECTS OF THE INVENTION Since the present invention has the above-described configuration, the upper and lower close contact members can be reliably projected and retracted with an extremely small number of component configurations. Therefore, manufacture and adjustment can be easily performed, and the weight of the moving wall can be reduced.

Moreover, since the elastic member interposed between the upper and lower lifting shafts can move up and down together with these lifting shafts, the distance from the upper edge of the moving wall to the ceiling surface and the lower edge of the moving wall. Even if there is a difference from the distance from the floor surface to the floor surface, the up-and-down movement of the expansion and contraction member causes an operation pressing action, and the force of pressing the upper contact member against the ceiling surface and the force of pressing the lower contact member against the floor surface. It becomes easy to equalize and. Therefore, it becomes possible to perform good light shielding and sound insulation.
