That is, the emergency opening device of the automatic door according to the present invention, as shown in Figures 1 to 9 attached to, normally open and close the operation, when the emergency is closed by rotating the revolving door 30 to open to the outside by emergency escape. It is the device which becomes possible.

The present invention is provided with a slide automatic door 20 which slides back and forth along the automatic door frame 10 as shown in FIGS. That is, the automatic sliding door 20 is reciprocated with respect to the automatic door frame 10 constituting the entire frame is opened and closed. In the example of the accompanying drawings, it will be seen that when the automatic sliding door 20 is positioned to the right, it is in a closed state, and when it is positioned to the left, it is in an open state.

As a result, a slide belt 14 wound around the upper side of the automatic door frame 10 with the bracket roller 13 on one side (right portion) is provided, and the slide bracket 12 fixed to the slide belt 14 is slide frame 21. It is fixed at. The slide frame 21 is also reciprocated by the slide belt 14 reciprocated by a motor (not shown).

Therefore, the slide automatic door 20 including the revolving door 30 connected below the slide frame 21 is opened and closed while reciprocating along the automatic door frame 10.

Of course, the rotary shaft (below the lower rotation axis 33) described below the rotary door 30 of the slide automatic door 20 moves along the bottom lane 41 formed below the automatic door frame 10, the slide automatic door 200 is stable Slide opening and closing is activated.

With the detailed configuration of the slide automatic door 20, as described above, the upper slide frame 21 reciprocating along the automatic door frame 10, and rotatably coupled to one side of the slide frame 21 It is made to include a revolving door (30).

It is opened and closed. The opening and closing operation due to this reciprocating movement is a normal opening and closing operation.

On the other hand, the revolving door 30 is rotated to open in the outward direction with respect to the slide frame 21, so that opening is an emergency opening. Therefore, the automatic slide door 20 and the revolving door 30 and the like according to the present invention is normally opened and closed by the slide reciprocating movement, in case of emergency is opened by the rotation of the revolving door 30.

And the revolving door 30, the slide frame 21 is provided with an upper rotary shaft 32 and the lower oblong rotary shaft 33 provided on the upper and lower sides of the rotary door 30 so that the rotary door 30 is rotated. Therefore, while rotating around the upper rotation shaft 32 and the lower oblong rotation shaft 33 is to be opened out.

3 and 9, the revolving door 30 is rotated and opened by the rotation angle c with respect to the automatic door frame 10 and the slide frame 21. In particular, the open revolving door is rotated about a rotation axis spaced apart by a distance d from one side edge. Therefore, when the rotation axis (upper axis 32 and lower oblique rotation axis 33, etc.) as the center, the weight of the revolving door 30 by the separation distance (d) spaced from one end is offset with the weight of the opposite revolving door will be.

In this case, when the general revolving door is opened, the center of the rotation shaft is positioned at the edge of the edge, so that the axial bending force is applied according to the weight of the entire revolving door so that the external shaft may be damaged. However, in the present invention, since the center has a rotation axis spaced apart from the edge by the separation distance (d), the external force applied to the rotation shaft is reduced by offsetting in both directions of the rotation shaft by the weight corresponding to the separation distance (d). Therefore, according to the present invention, the fatigue degree of the rotating shaft is lowered so that the rotating operation can be made stable and the breakage of the rotating shaft is reduced by that much.

Therefore, when the automatic opening of the emergency opening of the rotating door 30 is moved to the center portion to reduce the weight to be pulled to one side to prevent damage to the rotating door and the rotating shaft.
