[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a movable partition used to partition a single room so that a large room can be used as a small room if necessary. In particular, the present invention relates to a movable partition with a concealed door capable of closing a gap formed between the floor and a floor to improve airtightness and sound insulation performance.

[0002]

2. Description of the Related Art Conventionally, attempts to block a gap between a lower edge of a door and a floor surface or a lower frame of a door in order to prevent drafts and to improve soundproofing have been made, for example, by real opening. It is disclosed in JP-A-60-102392.

[0003] That is, the lower door closing device described in the above publication includes a closing member (pressure contact material) provided at the lower end of the door in a state of being urged upward, and a hinge-side end of the door. And a link mechanism for connecting the closing member and the driving rod. The retracting operation of the driving rod upon contact with the door frame when the door is closed is converted into a downward operation of the closing member by the link mechanism. When the door is closed, the closing member projects downward from the lower end of the door to close the gap between the floor and the drive rod and the door frame when the door is opened. When the contact state is released, the closing member is retracted so that the closing member does not hinder the opening and closing operation of the door.

In Japanese Utility Model Application Laid-Open No. 58-137786, a closing member (sealing base) is provided at the lower end of a latent door, which is retracted and urged, and is connected to the closing member at the side edge member of the main door. A kicker for lowering the closing member via the pivoting rod by contacting the pivoting rod, between a position where the kicker can contact the pivoting rod and a position where it cannot contact the pivoting rod; When the kicker is provided at a position where it can be adjusted and the kicker can be brought into contact with the rotating operation rod, the closing member is operated downward at the same time as the closing of the latent door to close the gap between the latent door and the floor surface. At the same time, when the latent door is opened, the closing member can be retracted, and when the kicker is set at a position where it does not abut against the rotating rod, the closing member remains retracted even when the latent door is closed. Sealing equipment for doors with hidden doors There has been disclosed.

[0005]

However, when the lower door closing device described in Japanese Utility Model Application Laid-Open No. 60-102392 is applied to a movable partition latent door, the closing member is closed when the latent door is closed. However, there is a problem in that the partition abuts on the floor surface, which becomes an obstacle when the partition itself is moved.

Further, in the device for closing a door with a concealed door described in Japanese Utility Model Application Laid-Open No. 58-137786, the closing member is kept retracted by moving the kicker to a position where it does not come into contact with the rotating rod. Therefore, although a tentative solution to the above-described problem that the closing member protruding downward becomes an obstacle to the partition movement is achieved, at the time of moving the partition, the closing member on the partition main body side is raised, and once the latent door is moved. Since the kicker must be opened and moved to a position where the kicker does not come into contact with the pivoting operation rod, there is a problem that the operation of moving the partition becomes complicated. Has been a challenge.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems in a conventional movable partition with a concealed door. When the concealed door is closed, a closing member projects downward and is formed between the concealed door and the floor surface. When the latent door is opened, the closing member retracts and does not hinder the opening and closing of the latent door. In addition, the closing of the gap by the closing member and the operation for releasing the gap are simple, and the moving operation can be performed easily and quickly. It is an object to provide a movable partition with a hidden door that can be performed.

[0008]

The movable partition according to the present invention is provided with a vertically movable closing member which projects downward from the lower edge of the partition and closes a gap formed between the lower edge and the floor surface. In a movable partition provided with a latent door, the latent door is urged to project from the hanging side of the latent door toward the partition main body side and abuts on a projection provided at the latent door side end of the closing member in the closed state of the latent door. Between the lower end edge of the latent door and the floor surface by moving up and down with the vertical movement of the closing member, It is characterized in that it has a configuration in which a second closing member for closing the formed gap is provided, and such a configuration of the movable partition is a means for solving the above-mentioned conventional problems.

[0009]

[Function of the invention] In the movable partition according to the invention,
The latent door is urged toward the movable partition main body side from the hanging side of the latent door and protrudes from the lower end edge of the latent door in conjunction with the retracting operation of the rod, and interlocks with the projecting operation of the rod. A second closing member to be retracted is provided.
On the other hand, the closing member attached to the partition body side protrudes downward from the lower end edge of the partition body by a predetermined lever operation, handle operation, or the like so as to close a gap formed between the partition body and the floor surface. The latent-door-side end of the closing member comes into contact with the tip of a rod projecting from the latent-door side in a state where the latent door is closed.

Therefore, when the closing member on the partition main body side is protruded downward by operating the handle, for example, with the latent door closed, the projection provided at the end of the closing member on the latent door side moves downward. Since the rod projecting from the latent door side is pressed and the rod is retracted, the second closing member on the latent door side also projects downward to close the gap formed between the latent door and the floor surface. Further, when the closing member on the partition main body side is raised by operating the handle in reverse, the projection of the closing member also moves upward, and the protruding and urged rod protrudes. Then, the second closing member on the latent door side also moves up, and the closed state of the gap is released.

That is, the closing or releasing operation of the closing member on the partition main body side simultaneously closes or releases the second closing member on the latent door side, so that the closing or releasing operation of the second closing member alone is unnecessary. As a result, the partition can be easily moved.

Further, when the latent door is opened in a state in which the gap between the floor and the floor is closed by the two closing members, the rod projecting from the latent door side and the projection of the partitioning body side closing member come into contact with each other. Since the state is released by the rotation of the latent door, the rod protrudes, whereby the second closing member provided on the latent door side retracts, so that the closed state is released only on the latent door side, and the second closed state is released. The member does not hinder the opening and closing operation of the latent door. Then, when the latent door is closed, the rod abuts on the projection of the partitioning body-side closing member and operates to retract, so that the second closing member projects downward again to close the gap between the floor and the floor. Will do.
