Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a movable partition in which a partition panel with a hinged door is movably provided along a rail.In particular, the lower structure of the partition panel and the hinged door has been improved. It is something.

(Prior Art) Conventionally, in a movable partition using a partition panel having sliding doors, the lower guide rail of the sliding door is configured to be movable up and down with respect to the partition panel, for example, in Japanese Utility Model Application Publication No. 1987-191272. The ones shown in are known. According to this structure, the partition panel can be easily moved by raising the lower guide rail and separating it from the floor surface, and the partition panel can be fixed by pressing the rail against the floor surface when installing the partition panel.

By the way, in this type of movable partition, when moving the partition panel, it is required to take into consideration the unevenness of the floor surface and make the gap between the lower end of the panel, that is, the lower surface of the lower guide rail, and the floor as large as possible. When installing the door, it is required to minimize the gap between the top surface of the lower guide rail and the bottom surface of the door.

However, in the above conventional structure, there is no means to reduce the gap between the top surface of the lower guide rail and the bottom surface of the sliding door, so if this structure is adopted for a partition panel with a hinged door, the following problems will occur: There is. In other words, increasing the amount of elevation of the lower guide rail is convenient when moving the partition panel, but a large gap will be created between the lower guide rail and the door during installation, and conversely, if the amount of elevation of the lower guide rail is reduced, Although the gap between the rail and the door can be made smaller when the partition panel is installed, if the floor surface is uneven when the partition panel is moved, there is a risk that the lower end of the partition panel will get caught on the unevenness.

(Purpose of the invention) The present invention was made to solve such problems.In a movable partition using a partition panel with a hinged door, when the partition panel is moved, the distance between the bottom edge of the panel and the floor surface is The gap between the panels is widened so that the panel can be easily moved even if the floor surface is slightly uneven, and when installing the partition panel, the gap at the bottom of the hinged door should be made large enough to not interfere with the opening and closing of the hinged door. To provide a movable partition that can be made small and used with good appearance.

(Structure of the invention) The present invention is a movable partition in which a partition panel is movable along a rail, an entrance is provided in the partition panel, a hinged door is provided at this entrance, and a movable lower frame is provided at the bottom of the entrance so that it can be raised and lowered. At the same time, both ends of the movable lower frame are connected to elevating means provided in the vertical frames on both left and right sides of the doorway, and a movable hem frame opposite to the movable lower frame is held at the lower end of the hinged door so as to be freely raised and lowered. It is characterized by the fact that
