BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of an automatic revolving door device provided at an opening of a building or the like.

[0002]

2. Description of the Related Art In general, a plurality of partition panels provided at an entrance / exit are rotated to shut off ventilation at an entrance / exit and open / close while constantly maintaining the indoor temperature. Revolving door devices are known. In such a configuration, the partition panel is supported by a rotating guide that constitutes the revolving door device, and is configured to rotate the doorway as the rotating guide rotates. By the way, in such a revolving door device, there is a fear that an emergency situation, an abnormal situation, or the like may occur, causing a panic condition. In such a panic condition, it is necessary to allow a large number of people to pass. Therefore, the partition panel is swingably connected to the rotating conductor, and in a normal operation, the partition panel assumes a partition posture for partitioning the doorway,
In the event of an emergency or the like, the partition panel is configured to be swung from the partition position to be in a folded position in which the partition panel is folded. In such a case, a holding means for holding the partition panel in the partition posture during the normal operation is required between the partition panel and the rotary conductor. No. 47900. In this device, a lock groove and a lock body that is immersed in the lock groove with a predetermined elastic force are provided between the partition panel and the rotary guide, and the lock body locks when the partition panel is in the partition posture. The lock body is configured to be immersed in the groove and applied to the partition panel with a pressing force greater than a predetermined value, so that the lock body can escape from the lock groove and be transformed into a folded posture. By the way, in this device, if the resilient pressure of the lock body is set small so that the partition panel can be easily folded in an emergency, etc., the lock body is easily unlocked when strong winds or gusts blow, There is a fear that the panel may be folded carelessly. Therefore, if the elastic pressure is set to a large value, a large force is required when trying to make the folding posture reverse, and as a result, the elastic pressure is not only forced to take a moderate value of these, but also depending on the installation location There is a problem because some do not meet the standard. Therefore,
As shown in JP-A-6-108735, each of the electromagnetic clutches provided on the rotating body opposite to each swing support shaft is connected to the swing support shaft of each partition panel, so that the normal rotation door device is used. During operation, the electromagnetic clutch is energized and the partition panel is held in the partition position, and if necessary, the electromagnetic clutch is de-energized, so that the partition panel can be transformed from the partition position to the folded position. An object is proposed, and in this way the problem is solved.

[0003]

However, in the above-described conventional apparatus, the cost is increased due to the configuration using the electromagnetic clutch, the number of parts is large, the structure is complicated, and the apparatus itself is enlarged. There's a problem. Also,
In the revolving door device, a plurality of partition panels provided with an entrance / exit portion having an oblong shape in a plan view, and configured so that the rotating guide is rotated in an oval shape with the center of rotation eccentric, and supported by the rotating guide. Is configured to rotate the doorway. And in this way, passers-by can pass through the entrance and exit with a linear flow line,
For example, when carrying a long baggage (such as skis) or when a stretcher enters or exits, it is possible to pass without any problem. Even in such a case, the partition panel is folded in preparation for the emergency or the like. To be able to do so. Therefore, in order to maintain the partitioning posture of the partition panel, it is assumed that an electromagnetic clutch device of the type described above is provided.However, the partition panel does not rotate around the rotation center as a fulcrum. , Since it moves in the shape of an ellipse, it is necessary to move the rotary guide itself provided with the electromagnetic clutch device together with the partition panel, which complicates the structure and additionally requires a separate moving space for the rotary guide. Need to be secured,
As a result, a layout problem that the whole device is not easily accommodated also occurs, and there is a problem that a place where the eccentric rotating door device can be disposed is limited,
These have problems to be solved by the present invention.

In the embodiment of the present invention constructed as described above, the partition panel 4 is swingably supported by a support bracket 8 which is a rotary guide, and can be folded in an emergency such as when an unexpected situation occurs. While it can be transformed into a posture, it is configured so as to be securely held in the partition posture during a normal use state and not to be folded by wind pressure. In this case, the partition panel 4
The mechanism for maintaining the partitioning posture is performed by magnetically attaching a support bar 8e extended from the support bracket 8 to an electromagnet 10 disposed above the partition panel 4. As a result, the number of components of the posture holding device, such as the one using the conventional electromagnetic clutch, is increased, and the device is not complicated and the size is not increased. Even if the apparatus is configured to move together with the partition panel body 4, there is no problem that the layout becomes complicated.

In the present embodiment, the support bar 8e is formed on the support bracket 8 which rotates together with the partition panel 4 in advance to guide the partition panel 4 in rotation. Since it is configured to be buried in the partition panel 4, only the space corresponding to the plate thickness of the support bar 8e magnetically attached to the upper end surface of the partition panel 4 needs to be secured. Space can be made small, and there is no problem that the installation place is limited.

The present invention is, of course, not limited to the above-described embodiment, but as an automatic revolving door device, the center of rotation of the revolving conductor is not eccentric and the partition panel has a perfect circular rotation locus. The present invention can also be implemented in a configuration in which the rotation is performed. Further, as the holding configuration of the partition panel, an electromagnet may be provided on the support bracket side, and the magnetized member may be mounted on the upper surface of the partition panel.
