DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving partition device which is preferably used in offices and the like.

[0002]

2. Description of the Related Art In a moving partition device of this type, a moving wall is suspended and supported by a ceiling rail in a state where a lower end portion of the moving wall is above the floor surface. Therefore, it is necessary to prevent sound or light from leaking from the gap between the lower end portion and the floor surface by some means at the installation position. Therefore, conventionally, a lower contact member is arranged on the moving wall so as to be able to move up and down, and the lower contact member is hung down at the installation position to block the gap. Therefore, the conventional type is classified into a jack type in which the lower contact member is forced to contact the floor surface and a simple type in which the lower contact member is contacted with the floor surface by its own weight. Among them, the simple one is such that the lower contact member is arranged at the lower end portion of the moving wall so as to be able to move up and down, and the lower end member is retracted from the position where the tip portion projects beyond one side edge of the moving wall. The horizontal operating rods are slidably disposed between the two, and the sliding operation of these horizontal operating rods and the raising / lowering operation of the lower contact member are always interlocked with each other via the action converting portion.

In use, first, the first moving wall is moved until one side edge abuts the fixed wall, and thereafter,
By sequentially contacting the second and subsequent moving walls with the other side edge of the previous moving wall, the horizontal operating rod is fixed to the other side of the previous moving wall immediately before each moving wall reaches the fixed position. The moving wall is brought into contact with the edge and the descending motion of the lower contact member is interlocked with the immersing motion of the horizontal operating rod that occurs next time through the motion converting unit to dispose each moving wall at a fixed position and at the same time to lower the lower end and the floor surface. The gap is automatically blocked by the lower contact member.

[0004]

However, in such a structure, it is necessary to accurately associate the time when the horizontal operating rod is depressed with the time when the lower contact member is brought into contact with the floor surface. The horizontal operating rod is retracted first and the lower contact member cannot move further down, creating a gap with the floor surface, or the lower contact member is lowered first and the horizontal operation rod cannot be retracted further. It is easy to cause a malfunction such as a gap being formed between the moving wall and the adjacent moving wall. Therefore, there is a problem that the setting work is extremely difficult. In addition, the floor surface is not always a high-quality horizontal surface, the whole is inclined,
There may be partial unevenness (unevenness) on the floor surface. In such a case, no matter where the setting standard is placed,
It becomes inevitable that the above-mentioned malfunction occurs somewhere on the floor.

[0005] An object of the present invention is to effectively solve such a problem.

[0006]

In order to achieve the above object, the present invention employs the following configuration.

That is, the moving partition device according to the present invention comprises a moving wall provided with a lower contact member, a horizontal operating rod, and a motion converting portion. The moving wall is suspended and movably supported on the ceiling rail in a state where the lower end portion of the moving wall is floated above the floor surface, and the lower contact member is arranged at the lower end portion of the moving wall so as to be able to move up and down. The operating rod is slidably disposed between a position where the tip portion projects laterally from one side edge of the moving wall and a position where the tip portion is retracted. The projecting / withdrawing operation and the raising / lowering operation of the lower contact member are partially interlocked with each other, and the lower contact member is suspended at the lower end so that the lower contact member can be relatively moved upward in conjunction with the projecting / withdrawing operation of the horizontal operating rod. The suspension rod and the biasing body that biases the suspension rod upward. Then, when the horizontal operating rod performs the immersing operation, the lower contact member is lowered onto the floor surface before it reaches the immersive position , and thereafter, the lower contact member moves.
Only the suspension rod descends while being grounded on the floor due to its own weight
It is characterized in that it is configured so that the operation can be continued .

As a concrete embodiment of the motion converting portion, a cam body having a cam surface fixed to the horizontal operating rod so as to be slidable integrally therewith, and having a cam surface inclined along the sliding direction, and moving up and down on the moving wall. A cam follower which is movably disposed and is brought into rolling contact with the cam surface of the cam body to move up and down in conjunction with the sliding motion of the cam body. The cam follower supports a suspension rod via a support shaft. Some of them are listed.

As a mode for smoothly performing motion conversion, a structure in which a long hole extending in the vertical direction for inserting a support shaft of a cam follower is provided in a moving wall, and a cam body is
A structure in which a guard surrounding the side surface of the cam follower is hung from both sides of the cam surface can be mentioned.

[0010]

With such a structure, normally, the motion converting portion acts as an urging body to pull the suspension rod upward together with the lower closely contacting member, and the suspension rod is moved upward to horizontally operate. The rod is carried in the protruding direction and held at the protruding end. From this state, if the moving wall is brought into contact with the fixed wall or another moving wall and further pushed in the same direction, the horizontal operation rod first starts sliding operation in the retracted direction against the biasing force of the biasing body. , Which accompanies the lowering movement of the suspension rod and the lower contact member via the movement converting section. Since the lower contact member descends to the floor surface before the horizontal operating rod reaches the retracted position, after that, the lower contact member remains grounded on the floor surface due to its own weight, and only the suspension rod operates the lower contact member. Continue descending motion by moving relative to each other.
Then, when the horizontal operation rod reaches the retracted position and one side edge of the moving wall abuts against the other side edge of the fixed wall or another moving wall, the descending operation of the suspension rod is completed at that point. In other words, this is one in which this lower contact member is first lowered to the floor surface by its own weight, and one side edge of the moving wall is moved to the fixed wall or another moving wall while sliding it on the floor surface with a slight delay. Performs the action of closely contacting the other side edge.

And

As shown in FIG. 2, the horizontal operating rod 3 has a tip portion 3a at a side frame member 11a of the moving wall 1 and an edge member 1.
3 is extended through one side edge 1a to the outside, the inner end 3b side is penetrated through the casing 41 of the motion converting portion 4, and is supported slidably in the horizontal direction by these through portions. .

As shown in FIG. 2, the motion converting section 4 fixes a casing 41 to the upper surface 11d of the lower frame member 11c of the moving wall 1, and in the casing 41, a cam mechanism 5 and a suspension rod 6 are provided. , And a spring 7 which is an urging body. More specifically, as shown in FIGS. 4 and 5, the cam mechanism 5 includes a cam body 51 made of a sheet metal material and a cam follower 52 rollingly contacting the cam body 51. 51 is formed by bending a sheet metal material from the center and enclosing it on the outer periphery of the horizontal operation rod 3 in the vicinity of the proximal end thereof, and by hanging the abutting end of the cylindrical portion 51b. A face plate portion 51c,
It is provided with a cam surface 51a formed by expanding the hanging bottom end into a U shape on the inner lower surface and a guard 51d formed on the outer edge. The tubular portion 51b is connected to the horizontal operating rod 3 by a pin or the like. Further, the cam surface 51a is tilted upward and upward in FIG. 4 along the axis of the horizontal operation rod 3, and when the horizontal operation rod 3 slides rightward in the figure together with the cam body 51, the cam follower is slid. Cam surface 51a rolling on 52
The position of is gradually lowered. On the other hand, the cam follower 52 is provided with a support shaft 52b on an upward U-shaped receiving frame 52a.
It is rotatably supported via, and between the receiving frame 52a and the guide member 11e embedded in the lower frame member 11c,
The spring 7 is installed elastically. The spring 7 constantly elastically urges the receiving frame 52a upward so that the cam follower 52 is brought into rolling contact with the cam surface 51a. Further, both ends of the support shaft 52b are inserted into the elongated holes 16a extending in the up-down direction of the plate member 16 fixedly provided at appropriate positions of the moving wall 1, and the rolling contact acting between the cam surface 51a and the cam follower 52 is performed. The reaction force in the direction is converted into the force in the vertical direction through the elongated hole 16a. The suspension rod 6
The upper end 6a is connected to the bottom plate of the receiving frame 52a by welding or the like, and the lower end 6b is inserted into the center of the spring 7,

Is extended to a position where it penetrates, and a nut 6c is fixed to its lower end 6b. The nut 6c is attached to the lower surface of the top plate portion 21a of the shielding member 21 to suspend the lower contact member 2 upward. In this mounted state, only the lower contact member 2 can be moved upward relative to the suspension rod 6.

Next, the operation of this embodiment will be described. Normally, in the motion converting section 4, the spring 7 urges the receiving frame 52a upward, and the urging force pushes the horizontal operating rod 3 to the left in the drawing via the cam follower 52 and the cam surface 51a, and at the same time, suspends the rod. 6 and the lower contact member 2 are pulled upward.
For this reason, the horizontal operating rod 3 is held at the position P that projects the maximum from the one side edge 1a of the entire moving wall 1, and the lower contact member 2 is held at the position that floats the maximum from the floor surface F. From this state, when the moving wall 1 is brought into contact with the fixed wall W or the other side edge 1b of the other moving wall 1 as shown in FIG. 1 and is further pressed in the same direction, the horizontal operating rod 3 first causes the spring 7 to move. The sliding operation is started in the direction of immersion against the biasing force, and the cam body 51 moves integrally therewith, and the cam follower 5 moves through the cam surface 51a.
2 is pushed down, and the suspension rod 6 is lowered together with the lower contact member 2 as shown in FIGS. The lower contact member 2 has a floor surface F until the horizontal operating rod 3 reaches the retracted position Q with respect to the moving wall 1.
After that, the lower contact member 2 remains grounded on the floor surface F due to its own weight thereafter, and only the suspension rod 6 moves the lower contact member 2 relatively upward to continue the lowering operation. Then, the horizontal operating rod 3 reaches the retracted position Q, and the one side edge 1a of the moving wall 1 becomes the fixed wall W or the other side edge 1b of the other moving wall 1.
When it comes into contact with, the descent operation of the suspension rod 6 is completed at that point. That is, in this device, the lower contact member 2 is first lowered to the floor surface F by its own weight, and while sliding it on the floor surface F, the one side edge 1a of the moving wall 1 is fixed to the fixed wall W with a slight delay. And the other side edge 1b of the moving wall 1 are brought into close contact with each other.

Therefore, by using this moving partitioning device, even if the floor surface F is entirely inclined or the floor surface F is partially uneven (uneven), it is simple. The lower contact member 2 of the moving wall 1 arranged everywhere can be properly grounded on the floor surface F only by the adjustment work. Sa
In addition, the lower contact member 2 has its own weight against the floor surface F even after descending.
Since they come into contact only with each other, their sliding resistance is small and
No excessive force is required to install the moving wall 1. Accordingly
The floor F when installing the moving wall 1
The possibility of damaging the wall 1 is also reduced.

The present invention is not limited to the above-described embodiments, but various modifications can be made without departing from the spirit of the present invention.

[0020]

As described above, the moving partitioning device of the present invention lowers the lower contact member to the floor surface by its own weight first, and slides the lower contact member onto the floor surface while it is attached to the suspension rod. While moving relatively, one side edge of the moving wall is brought into close contact with the other side edge of the fixed wall or another moving wall with a slight delay. For this reason, the horizontal operating rod is first sunk, and the lower contact member cannot move any further, creating a gap between the lower operating member and the floor surface. It is not possible to immerse and there is no inconvenience such as creating a gap between adjacent moving walls, and with a simple adjustment work, the lower contact members of the moving walls arranged everywhere can be properly placed on the floor surface. It is possible to keep it grounded. Furthermore, secret
After the contact member descends, it will contact the floor surface only by its own weight.
Therefore, its sliding resistance is small and it is impossible to install a moving wall.
There is no need for power. Therefore, to install the moving wall
It may hit the floor and damage the moving wall.
Less.
