Abstract

<P>PROBLEM TO BE SOLVED: To provide a rotary door preventing users from being injured or died by the catching accident when their hands, legs, or body are caught by a fine gap between the door stile and the outer frame as the door is closed. <P>SOLUTION: When one's hands, legs, or body is caught in a gap between the door stile 4 and the outer frame 3 or drawn therein when the door is in rotation, When a force larger than a predetermined figure acts on the door outer stile 4, stopper 12 comes off, and the door is folded at the middle and hence, a small gap between the door stile 4 and the outer frame 3 is widened in a wide space hence, even if hands or body is caught, a necessary space for the hands or the body can be secured, accordingly, such an accident that hands, body are caught in a narrow gap or drawn therin can be prevented. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

Detailed Description of the Invention

TECHNICAL FIELD OF THE INVENTION

In this invention, when a door rotates and a person tries to pass, when a limb or body is caught in the gap between the door frame and the outer frame, the sensor operates and the door frame and the outer frame are stopped until the rotating door stops. Things related to preventing injuries and crushing accidents, etc., because the limbs and body are caught in the gap with the frame, the middle of the door bends to cause an accident, and an emergency space is created between the outer frame It is.

Conventional revolving doors can be detected and actuated by a sensor, which only stops the rotation of the door, and even if a limb or body is caught in the gap between the door frame and the outer frame, it can be pinched or pulled in until it stops rotating. There was no device that widened the gap between the door frame and the outer frame.

Problems to be solved by the invention

Until now, there were the following drawbacks.
When the revolving door is rotating, if a limb or body is caught in the gap between the door frame and the outer frame, the limb or body is caught in the gap between the door frame and the outer frame until the sensor detects it and the revolving door stops. As such, the present invention has been conceived to eliminate this drawback.

Means to solve the problem

In an emergency where the door is rotating, when excessive force is applied to the revolving door vertical outer frame (4), the door bends from the revolving door vertical inner frame (5) in the direction opposite to the moving direction of the revolving door. It is a revolving door with a structure that is designed to prevent and solve accidents involving limbs and bodies by providing a temporary large space in the gap between the vertical outer frame (4) and the frame (3). .

Embodiments of the present invention will be described below.
Until now, when the revolving door is rotating, even if the limbs and body are caught in the gap between the revolving door vertical outer frame (4) and outer frame (3), the door narrowing sensor (2) is detected and activated, Until the door stopped rotating, the limbs and body were pinched or pulled into the gap. However, when the force applied to the vertical frame of the revolving door is applied, the stopper ▲ 12 ▼ comes off. By turning from the middle of the door part of the revolving door (revolving door vertical middle frame ▲ 5 ▼) until the revolving door stops, the revolving door vertical outer frame ▲ 4 ▼ And the outer frame (3) are used in a structure in which a small gap extends into a large space.

The invention's effect

When the door of the revolving door is bent from the middle, a small gap between the door outer frame and the outer frame spreads into a large space, so that even if a limb or body is caught, it will not lead to a major accident.

Claims (1)

During rotation of the revolving door, when a person or object is caught between the rotating inner door frame and the fixed outer frame, if a certain force is applied, the door will be bent and the door frame A revolving door with a structure to prevent accidents by providing a space between the outer frame.
