DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 5 are views for explaining one embodiment of the revolving door device of the present invention.

In this embodiment, a semi-circular arc-shaped curved track 3 formed of a stainless steel pipe or a round bar is provided above a doorway 2 of a chamber. As shown in FIGS. 1 and 2, the track 3 is connected to the front end of a flat track support 4 having one end attached to the upper part of one front wall 16 of the entrance 2 by the outer periphery of the track 3. The track 3 is fixed to an intermediate portion of the surface by welding or the like to prevent the center of the track 3 from hanging down.

The track 3 is provided with three hanging members 5 formed in a C-shape and having open side portions so as to be slidably fitted, but the number of the hanging members 5 is four or more. It is also possible. The C-shaped opening of the suspender 5 is used to slide on the track support 4.

The upper portions of the arc-shaped curved door plate 6 are suspended by the suspenders 5 so that the intervals between the suspenders 5 are substantially equal. As shown in FIG. 1, the revolving door device includes one side portion 14 of the door plate 6 at a position where the entrance 2 is opened, and a door at a position where the entrance 2 is closed as shown in FIG. The width of the door plate 6 is largely formed as shown in FIG. 2 so that the other side portion 15 of the plate 6 can overlap with the one side portion 16 of the entrance 2.

On the lower surface, which is the lower end of the door plate 6,
As shown in FIGS. 3 and 4, an inverted concave portion is provided on the lower surface of the door plate 6, and an inner rail 22 and an outer rail 23 which are curved in the same arc shape as the door plate 6 and face each other are provided.

As shown in FIGS. 1 and 2, a base 30 of a lower support 29 for supporting the lower end of the door plate 6 is mounted inside the lower end of one front wall 16 of the entrance 2. is there. FIG. 3 is an enlarged drawing of FIGS.
As shown in FIG. 5 to FIG. 5, the lower support 29 has a base 30 attached to the inside of the lower end of one front wall 16 of the entrance 2 by a set screw in the vertical direction. Note that the base 30 may be fixed to the floor.

An arm 31 extending inward from the upper end of the base 30 is provided, and a tip 32 extending between the inner rail 22 and the outer rail 23 above the inner end of the arm 31. Is provided.

At the distal end 32 of the lower support 29, a rectangular roller mount 38 having a long side extending in the longitudinal direction of the inner rail 22 and the outer rail 23 is provided between the inner rail 22 and the outer rail 23 in the horizontal direction. It is swingably mounted on the shaft.

As shown in FIGS. 3 to 5, and especially in FIG.
A first roller 39 is axially mounted at one end of the upper surface of the roller in the longitudinal direction and near the inner rail 22, and at the other end of the upper surface of the roller mounting body 38 in the longitudinal direction and near the outer rail 23. The second roller 40 is axially mounted at the position of.

The roller mounting body 38 is provided with a first roller 39 by means of a spring (elastic body) 41 formed as a helical spring, the main body of which is externally fitted to the distal end portion 32 of the lower support body 29.
Is pressed against the inner surface of the inner rail 22, and the second roller 40
Is formed so as to be pressed against the inner side surface of the outer rail 23, and the first roller 39 and the second roller 40 are formed so as to suppress the lateral vibration of the lower end portion of the door plate 6.

That is, the inner rail 22 and the outer rail 2
The moving distance (length of the rail) of the rail 3 is different because the rail is curved, but the rollers that press against the rail are the first roller 39 for the inner rail 22 and the second roller 39 for the outer rail 23.
It is shared with the roller 40. Therefore, the inconvenience (slide displacement) caused by the different lengths of the rails can be handled as different rotation speeds of the rollers 39 and 40, and the door plate 6 can be stably rotated.

Incidentally, the radius of each roller is changed according to the length of each rail (according to the distance from the center of curvature of the inner rail 22 and the outer rail 23) so that the number of rotations is the same. May be set. Thereby, noise can be further prevented.

The inner rail and the outer rail are connected to the door plate 6.
The inner rail may be provided on the back side (concave side) of the above, and the outer rail may be provided on the front side (convex side). In this case, two rollers sandwich the door plate 6.

Further, each roller may be formed in a spherical shape, and each roller may be mounted by a different roller mounting body. Since the first roller 39 and the second roller 40 are mounted by different roller mounting bodies in this manner, each roller is allowed to move independently, and the position of each roller can be pressed against each rail while being finely adjusted. It is possible to rotate the door plate 6 more stably.

The present invention relates to a rotating door apparatus in which an arcuately curved door plate 6 is suspended on an arcuately curved track 3 provided above an entrance 2 of a chamber. And an inner rail 22 and an outer rail 2 which are curved in an arc shape and face each other.
3, a lower support 29 for supporting the door plate 6 is attached to the fixed body, and a first roller 39 rotatably pressed against the inner rail 22 by an elastic body 41 on the lower support 29 and an elastic body 41. This is provided with a second roller 40 that is rotatably pressed against the outer rail 23.

Therefore, the lower end of the door plate 6 is
The first roller 39 and the second roller 40 pressed by 1
This can prevent lateral vibration, and can suppress vibration and noise caused by the lower part of the door plate 6. Further, rails and the like need not be provided on the floor of the entrance to suppress the vibration of the door plate 6, so that the appearance is good.
