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.

In this way, the upper and lower contact members are adapted to be pushed and retracted by a contact member drive mechanism installed in the moving wall. A conventional close contact member drive mechanism has an operation shaft having two types of screw parts that are mutually reverse screws, a pair of nuts screwed into the screw parts of the operation shaft, and a link member having a diamond shape. The left and right pivot points are pivotally connected to the nuts 4
It is provided with a point link and an up-and-down shaft connecting the upper and lower pivot points of the four-point link and the upper and lower contact members, respectively, and 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, with this alone, 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, the upper contact is close. A downward reaction force that acts on the upper pivot point of the 4-point link from the upper lifting shaft that supports the member, and a lower reaction shaft that acts on the lower pivot point of the 4-point link that supports the lower contact member. There is a difference between the upward reaction force and the bending stress acting on the operating shaft. As a result, there are problems that the screwed portion is overloaded and a large operating force is required, and that a large load acts on the bearing portion that supports the operating shaft, resulting in reduced durability.

The present invention aims to solve such problems.

[Means for Solving the Problems] The present invention adopts the following configuration in order to achieve the following 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 and lower contact member, a contact member drive mechanism, a floating frame, and a floating frame support mechanism. It is equipped with. The ceiling rail has a continuous opening on the lower surface thereof, and the traveling body is disposed so as to be able to travel inside the ceiling rail. 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, and the moving wall is attached to the ceiling rail via the suspension rod and the traveling body. It is movably suspended and supported. The upper and lower contact members are arranged at upper and lower edges of the moving wall so as to project and retract toward the ceiling surface and the floor surface, and the contact member drive mechanism operates in a substantially horizontal operation. The upper and lower lifting shafts supported by the shaft are configured to allow the upper and lower contact members to project and retract at the same time. The floating frame is held in the moving wall so as to be able to move upward and downward, and the floating frame support mechanism is configured to elastically float and support the floating frame at an intermediate position in the floating range. Has been done. The operating frame of the close contact member drive mechanism is supported by the floating frame.

As a specific mode of the close contact member drive mechanism, an operating shaft having two types of screw parts which are mutually reverse screws, a pair of nuts screwed into each screw part of the operating shaft, and a link 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 of the four-point link and the upper and lower contact members are pivotally connected to each other in a diamond shape. There is an elevator including an elevating shaft connected to each other, and the operating shaft is supported by the floating frame.

The operating shaft may be rotated forward and backward by the driving force of the motor, or may be manually rotated.

[Operation] With such a configuration, when the operation shaft is rotated and the upper and lower contact members are projected, the floating frame moves upward and downward, and the pressing force of the upper and lower contact members is made uniform. To do. That is, for example, when the upper contact member first comes into contact with the ceiling surface, the reaction causes the floating frame to move downward against the urging force of the floating frame support mechanism. On the contrary, when the lower contact member first comes into contact with the floor surface, the floating frame moves upward due to its reaction. When the upper and lower contact members come into contact with the ceiling surface and the floor surface, respectively, and when the operation is further continued,
The lower contact member is pressed against the ceiling surface and floor surface. At that time, the downward reaction force acting on the 4-point link from the upper lifting shaft and the upward reaction force acting on the 4-point link from the lower lifting shaft. The floating frame moves to a position where the reaction force and the reaction force balance each other, and is supported by floating. Therefore, the pressing force on the ceiling surface and the floor surface of the upper and lower contact members becomes uniform,
A large bending stress does not act on the operating shaft.

As shown in FIG. 1, the floating frame 6 is a rectangular frame formed by connecting left and right side frame members 61 with upper and lower frame members 62 and 63.
On the outer surface of the side frame member 61, a protrusion 64 made of synthetic resin or the like and having a U-shaped cross section is provided so as to project.
It is arranged between b and 52c. A guide frame member 58 is fixedly provided between both ends of the horizontal members 52b and 52c, and as shown in FIGS. 1 and 2, the protrusion 64 is formed on the inner surface of the guide frame member 58.
A rail 59 is fixedly installed to guide the rail up and down.

As shown in FIG. 1, the close contact member drive mechanism 7 has a horizontal operation shaft 71 having two types of screw parts 71a and 71b which are mutually reverse screws, and each screw part 71a of the operation shaft 71. , 71b and a pair of nuts 72 screwed together, and link members 73a to 73d are pivotally connected in a rhombus, and left and right pivot points 73e are four-point links 73 pivotally attached to the nuts 72, respectively. The upper and lower pivot shafts 74 and 75 connecting the upper and lower pivot points 73f and 73g of the four-point link 73 and the upper and lower contact members 54 and 55, respectively, are provided. The shaft 71 is supported by the floating frame 6.
That is, one end 71c of the operation shaft 71 is pivotally supported on one side frame member 61 via a bearing 76, and the other end 71d side is provided on the other side frame member 61 via a box 77 having a helical gear or the like built therein.
To support. The other end 71b of the operating shaft 71 has a guide frame member 58.
Is extended through the end edge member 51,
A handle (not shown) is attached to the other end of 71 so that it can be manually rotated. Thus, the guide frame member 58 and the end edge member 51 are provided with elongated holes each having a size corresponding to the vertical floating distance of the floating frame 6. Operating axis 71
Is a motor 78 via a gear arranged in the gearbox 77.
The operating shaft 71 can also be rotated by the rotational force of the motor 78. The elevating shafts 74 and 75 are pipe-shaped proximal end pipe members 74a and 75a,
Tip shaft members 74b, 75b engaged with the inner circumferences of the tip end portions of the base end members 74a, 75a so as to project to a predetermined length, and a pressing spring for urging the tip shaft members 74b, 75b in the projecting direction. 74c, 75c, and the tip shaft material 74
b and 75b are pivotally attached to the central portions of the biasing arms 54f and 55f.

The gravity applied to the upper and lower close contact members 54, 55 and the close contact member drive mechanism 7 acts on the floating frame 6, and the free floating frame 6 is moved by the free moving frame support mechanism 8. It is elastically levitated and supported at an intermediate position. The floating frame support mechanism 8 includes a guide pin 81 protruding from the horizontal member 52c.
Is slidably penetrated through the lower frame member 63 of the floating frame 6, and a compression coil spring 82 is wound around the guide pin 81 between the horizontal member 52c and the floating frame 6. It is a thing.

With such a configuration, when the operation shaft 71 is rotated manually or electrically to cause the upper and lower contact members 54 and 55 to project, the floating frame 6 floats up and down to bring the upper and lower close contact members into close contact with each other. Element
The pressing force of 54, 55 will be equalized. That is, for example, when the upper contact member 54 first comes into contact with the bottom surface of the ceiling rail 1 that forms a part of the ceiling surface C, the reaction force causes the floating frame 7 to resist the urging force of the floating frame support mechanism 8. And move down. On the contrary, when the lower contact member 55 first comes into contact with the floor surface F, its reaction causes the floating frame 8 to move upward.
When the upper and lower contact members 54 and 56 are in contact with the ceiling surface C and the floor surface F, respectively, and when the operation is further continued,
The lower contact members 54, 55 are pressed against the ceiling surface C and the floor surface F, but at this time, a four-point link from the upper lifting shaft 74
Downward reaction force acting on 73 and lower lifting shaft
The floating frame 6 moves to a position where the upward reaction force acting on the four-point link 73 from 75 is balanced, and the floating frame 6 is levitationally supported. Therefore, the pressing force of the upper and lower contact members 54, 55 to the ceiling surface C and the floor surface F becomes uniform, and at the same time, a large bending stress does not act on the horizontal operation shaft 71.

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

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

Further, the elevating shaft of the close contact member drive mechanism may not have a pressing spring in the middle thereof. However, according to the present invention, since the upper and lower close contact members can be differentially pressed, it is not necessary to absorb the stroke difference between the upper and lower close contact members by the pressing spring.

EFFECTS OF THE INVENTION Since the present invention is configured as described above, there is a difference between the distance from the upper edge of the moving wall to the ceiling surface and the distance from the lower edge of the moving wall to the floor surface. Even if the contact surface timings of the upper and lower close contact members are significantly different from each other, the vertical pressing motion of the floating frame causes a differential pressing action, and the force of pressing the upper close contact member against the ceiling surface and the lower close contact member. Can be always equalized with the force pressing on the floor. Therefore, the reaction force acting on the operating shaft of the close contact member drive mechanism can be constantly balanced, and the bending stress acting on the operating shaft can be effectively prevented. Therefore, it is possible to solve the problems that the operation force is unreasonably increased due to excessive force applied to the screwed portion and the durability of the operation shaft and the bearing supporting the operation shaft is reduced.
