[0003]

In the conventional folding rotary door, since the upper rail and the upper arm are arranged side by side in the thickness direction of the door body, the thickness of the door body around the upper rail is reduced. There is a problem that the dimension in the direction becomes large.

Therefore, there has been proposed a method in which an upper rail and an upper arm are vertically arranged side by side, and this method has an advantage that the size of the door body in the thickness direction can be reduced. However, on the other hand, the size in the vertical direction is increased, and there is a problem that the height of the opening must be increased and the vertical size of the door body must be reduced accordingly.

SUMMARY OF THE INVENTION The present invention has been made in view of such a situation, and does not increase the height of the opening or reduce the vertical dimension of the door body, and makes it possible to reduce the size of the door body in the thickness direction around the upper rail. An object is to provide a folding revolving door that can be made smaller.

Another object of the present invention is to apply the present invention to a folding revolving door having a structure in which an upper arm and a lower arm are not interlocked.

It is still another object of the present invention to appropriately select the cross-sectional shape of the upper arm according to the outer surface shape of the upper rail so that the optimum strength of the upper arm can be easily obtained.

The upper rail is formed of a plate material having a bent cross section having a lower surface plate portion corresponding to at least a lower surface and a side surface plate portion corresponding to one side surface. Thus, it is possible to reduce the dimension of the door body in the thickness direction of the door body around the upper rail without increasing the height of the opening or reducing the vertical dimension of the door body.

The present invention also provides a door body disposed in an opening formed in a wall; swinging around a position near one end of the opening as a fulcrum; And an upper arm and a lower arm pivotally attached to the lower end and the upper end, respectively, on the upper lower surface and the lower upper surface of the opening, and at a longitudinal middle portion of the upper end of the door body and a longitudinal middle portion of the lower end of the door body. An upper rail and a lower rail for movably supporting the upper fulcrum member and the lower fulcrum member respectively provided;
The upper rail is formed of a plate material having a bent cross section having a lower surface plate portion corresponding to at least a lower surface and a side surface plate portion corresponding to one side surface. Thus, the present invention can be applied to a folding revolving door having a structure in which the upper arm and the lower arm do not interlock.

[0010] The present invention is further characterized in that the upper arm is formed to have an L-shaped cross section or a U-shaped cross section. Thus, the sectional shape of the upper arm can be appropriately selected according to the outer surface shape of the upper rail, and the optimum strength of the upper arm can be easily obtained.
