Abstract

<P>PROBLEM TO BE SOLVED: To prevent biting accident resulting from no clearance at the time when a door body, a rotary door, an automatic rotary door pass through a building side frame. <P>SOLUTION: A space is imparted to a door, a rotary door body a in advance, a safety board c is usually installed to fill the space, The usual use condition of the safety board c is kept by a twist spring g. In emergency, the safety board body is bent by a hinge to bring a safe space. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to shapes of doors, revolving doors, revolving automatic doors, and the like.

  A conventional door is constructed with a door body and a frame on the building side. The shape of the revolving door is constructed by a door revolving part and a building-side frame.

However, according to the above technique, there is no safe space even if a situation occurs between the door body and the frame while passing through the door, or between the door body of the revolving door and the frame on the building side. Therefore, if a person is caught, there is a danger of falling into a fatal situation.
Therefore, an object of the present invention is to provide an apparatus that can create a safe space when a situation where it is fundamentally pinched.

Means to solve the problem

In order to solve the above problems, the present invention is a safety device characterized in that a door or a door body of a revolving door is previously provided with a space, and a safety plate is usually provided to fill the space. .
In addition, the safety plate is a safety device characterized in that the normal use state is maintained by a torsion spring and the safety plate is bent by a hinge in an emergency to create a safe space.

The invention's effect

  Since the present invention is configured as described above, it is possible to avoid injuries and fatal situations due to pinching of the arms, legs, and head of a person passing through a door, a revolving door, and a revolving automatic door.

  As shown in FIGS. 1 and 2, the conventional door does not have a safe gap between the door, the revolving door door a, and the frame b on the building side.

  As shown in FIG. 3 and FIG. 4, even if an obstacle is sandwiched between the door, the revolving door door a, and the frame b on the building side, the safety plate c itself is caused by the obstacle. It is a structure that bends due to the resistance, the door body, and the inertia of the revolving door door body.

  As shown in FIGS. 5 and 6, when an obstacle enters between the door body, the revolving door door body a, and the building side frame b, the safety plate c itself is bent. In the case of a rotary automatic door, an emergency stop can be performed by installing a sensor on the door body.
