DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency escape surface grid which is installed in a window opening of a building and can be opened and closed for escape in an emergency.

[0002]

2. Description of the Related Art For example, an emergency escape system using a rectangular lattice body which is capable of forming an escape opening in front of a window by, for example, being dropped below a window or flipping up and rotating above a window. Instead of a plane grid, the present inventor has disclosed, for example, Japanese Patent Application No.
No.3, a plurality of crosspieces are connected by a telescopic link mechanism, and the telescopic surface grid is formed so as to be able to simultaneously expand and contract;
A locking device that locks the telescopic link mechanism by locking the other end or an intermediate bar under the fixed one end of the telescopic surface grid in the expanding and contracting direction has been proposed. For example, a lever handle provided with a locking member for locking to a metal fitting disposed on the beam side of the stretchable surface lattice by rotating this inside the room of the stretchable surface lattice is used. The turning radius of the lever handle is set to be longer than the distance between the sash door and the sash door, for example, the guide rail or the support member provided on the support member, and the length of the sash door is set to be longer than that. In the sash door closed state in which the sash door is closed, the turning operation of the lever handle in the lock device is disabled.

[0003]

In this case, for example, in the event of a fire or the like, an emergency opening and closing of the surface grid is performed, and in particular, opening and closing of the folding is performed to obtain an escape opening in front of the window and prevent the lever handle from rotating in normal times. By doing so, it is possible to provide a preferred emergency escape surface grid that disables the operation of the locking device and prevents the surface grid from being opened from the outside to secure the security of the installation of the surface grid. For example, when the sash door is open and can be opened even if it is closed because the sash door is not opened or the crescent is not locked, the rotation of the lever handle from outside and the operation of the lock device by this are performed. This makes it possible to open and close the screen grid from the outside, and the security is impaired.
