Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a revolving door device which is installed at a doorway of a building. The present invention relates to a revolving door device that allows a large number of people to pass through.

[0002]

2. Description of the Related Art Conventionally, since a revolving door device has a function of effectively blocking the inside and outside of a building even when the door is opened and closed, it has been conventionally used in many places as an entrance door. In general, this type of revolving door device has a structure in which a plurality of doors are installed radially with respect to a rotating shaft vertically installed between the ceiling and the floor and rotate between the facing arcuate entrance / exit wall surfaces. Although the effect is very good, it is not suitable for the function of passing a large number of people at one time and the function of loading and unloading a large object.

Therefore, as shown in FIG. 10, the conventional revolving door apparatus has a structure in which four doors are folded in one letter (a) or a structure in which all four doors are folded outward (b). However, since the rotating shaft is at the center, not only is it prevented from passing wide objects such as wheelchairs, but also a large amount of traffic is obstructed, and securing an emergency evacuation exit has become a problem.

Therefore, as shown in FIG. 9 (a) or 9 (b), the structure is such that the rotary shaft can be moved in the side wall direction with the door folded, or the rotary shaft can be detached and passed through. There has been invented a revolving door device having a structure capable of enlarging a possible width and allowing a large amount of traffic (Japanese Patent Publication No. 3-66480).

[0005]

However, in these revolving door devices, the operating procedure must be well known in advance, and the structure and operation are difficult for a door device used by an unspecified user. Each time, the rotating shaft must be removed from the ceiling and floor to increase the width that can be passed or the structure must be changed to allow a large amount of traffic, which has the drawback of making it impossible to deal with emergency evacuation. It was

The present invention has been made in view of the above problems, and has a structure in which the rotary shaft structure is eliminated from the passage space, and the doors radially pivoted when the passage width is enlarged or during an emergency evacuation, Release the outer edge of each door to use as a pivot axis and automatically fold it in the direction of passage, allowing large numbers of people to carry in and out of wheelchairs and large items without requiring complicated operations or prior knowledge, or to pass through a large number during emergency evacuation. It is an object of the present invention to provide a revolving door device having a new structure which enables the above-mentioned and is approved as an evacuation guide.

[0007]

A revolving door device of the present invention is rotatably supported above a floor of an entrance / exit opening of a building and is rotatably driven by a motor, and a vertical direction of the ceiling structure. 4 pivotal pivot shafts for pivoting the door, and 4 doors fixed to the pivot shafts and arranged so that the swing ends face each other at the central axis position of the rotary door. The gist of the present invention is that the four doors are integrally rotated with each pivot shaft.

In the above revolving door device, each door can be opened and closed as needed, and the automatic fixed release mechanism of each door is an automatic rocking mechanism provided at the suspension base of the door and having an automatic fixed release structure. , And an electromagnetic lock provided between the door and the ceiling member. Note that the revolving door device can also be implemented as a three-door revolving door device by the same device and mechanism as described above.

When the revolving door device passes through the doorway and passes from the outdoor side to the indoor side or from the indoor side to the outdoor side, the revolving door device can move while rotating the door as in the conventional automatic revolving door. it can. Also, when a wheelchair passes by or loads or unloads a large baggage, the four doors stop at 45 ° to the direction of passage of the doorway.

In this state, the electromagnetic lock is released, and each door is folded toward the fixed wall by the automatic swing mechanism via the automatic fixed release mechanism. At this time, when trying to pass from the inside of the building to the outside or from the outside to the inside, the structure is such that the doors are folded in an order that does not support the passage. Since this revolving door device has no shaft structure at the center of rotation, a relatively large passage width can be secured with respect to the opening width of the fixed wall, and the wheelchair can be passed sufficiently.

When an emergency signal is input, the automatic fixing and releasing mechanism releases the fixing of all the doors, so that each door can be swung and folded in the pushing direction. Therefore, if a person rushes in from the inside, the four doors open to the outside. Even if it is not pushed by a person, the four doors are opened to the outside after stopping in the above 45 ° direction.
