Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll-up type door having a rollable or foldable sheet member as a constituent element, and more particularly, a roll-up type door in which a flexible sheet member is pulled out from a storage portion and used. It is about doors.

[0002]

2. Description of the Related Art Various types of structures using panels, which are included in the broadly-defined "partition" category such as doors or partitions, have been proposed in the past, and many have been actually used. For example, a fairly large hard panel made of wood, etc., is suspended by multiple ceiling rails so that it can be moved independently, and when necessary, it is sequentially pulled out from the storage section to partition a large room into two or more partitions. It is often used in hotels that provide banquet halls.

Further, a so-called accordion curtain and a hard curtain in which strip-shaped panels are connected in a bendable manner have also been proposed (for example, Japanese Utility Model Publication No. 63-24774).

[0004]

The present invention is suitable as a relatively lightweight and particularly retractable door in which the strip-shaped members are flexibly connected among the conventional partitions as described above. It provides a structure.

In the conventional proposal, for example, such a roll-up door is constructed by closely adhering a wooden strip-shaped plate material to one surface of a vinyl chloride sheet or the like, with substantially no space therebetween. As a result, when it is pulled out from the storage section and placed in a linear posture, the strip plate material that forms one surface does not seem to be a bendable door that is aligned and looks like a single plate at first glance. Features are obtained.

[0006] On the other hand, on the other hand, on the other hand, when a large number of strip-shaped members are flexibly connected by a single sheet, a strong load is applied to the sheet, which causes a problem in durability and one side of the sheet. The productivity is poor because a pressing process to securely fix the strip-shaped member is required, and when wood material is used as the strip-shaped member, it is exposed to the outside air on one side, so it absorbs moisture and causes Therefore, there is a problem that an appropriate surface treatment is required to prevent this, the selection of usable materials is limited, and the cost tends to be high.

The present inventor has conducted various studies in consideration of the above, and can provide a retractable door whose manufacturing cost is low, and a novel retractable door device which is devised so as to have excellent durability. It was made for the purpose of providing a door.

Another object of the present invention is to provide a retractable door which is not only inexpensive and excellent in durability as described above, but also has a feature that a case for accommodating a sheet member can be omitted. To do.

[0009]

The first feature of the retractable door according to the present invention is that two rolls having a predetermined length in a vertical vertical posture and being bonded to each other in a vertical vertical posture. Sheet member having a structure in which a plurality of vertically elongated bar members extending in the vertical direction across the upper and lower ends of the flexible seat sheet are inserted and fixed at appropriate intermittent intervals, and the bar members positioned at least at both ends of the sheet member. A ceiling rail and a floor rail that engage with the upper and lower ends of the rod and guide the movement of these rods along a predetermined track, and the ceiling rail and the floor rail form an arc shape that defines the sheet member in advance. Alternatively, it has a withdrawal track portion for making a linear withdrawal posture, and a spiral-shaped storage track portion for winding this sheet member in a spiral posture, and the spiral-shaped storage track portion has a spiral-shaped storage track portion. In the outermost track, the withdrawal track part In the place that has been continuous. In this structure, it is preferable to engage the upper and lower ends of all the bar members constituting the sheet member with the ceiling rail and the floor rail because the posture during movement can be made stable and reliable.

The present invention further comprises the above-mentioned sheet member and a ceiling rail that suspends the upper ends of these rod members and guides the movement of the rod members along a predetermined track. It is another object to provide a retractable door having a withdrawal track portion for making the sheet member into a predetermined arcuate or linear withdrawal position and a storage track portion for winding the sheet member in a spiral shape. It is a feature of.

With a structure in which a large number of elongated bar members are vertically inserted between the pair of sheets at an appropriate intermittent interval, the strength required for the cover sheet forming the flexible sheet member can be reduced, The durability when using a sheet with the same level of strength can be greatly improved, and since the bar material used as the core material is not exposed to the outside air, there are no problems such as "sledding" and the core material can be seen from the outside. There is no restriction on the material selection.
