Description

Rotating Folding Safety Screen {Insect net assembly}

The present invention relates to a folding folding safety screen that is rotated and opened by folding in half.

In general, the insect screen is designed to maintain the ventilation of the room in the summer and to prevent the insects from entering the room. The insect screen is composed of a mesh body and a frame supporting the circumference of the mesh body. The fixed type is mainly used for windows, and since the opening operation is impossible, it has the disadvantage of making it impossible or difficult for people to evacuate through the window in an emergency such as a fire.

On the other hand, the open screen is made of a structure that can be opened and closed to allow escape from the indoor to the outdoor in an emergency, and is divided into a rotary type and a slide type according to the opening and closing method.

Among them, the rotating screen is rotatably connected to one side of the frame by a hinge on the window frame or the door frame like a general door, and is provided with a locking device at the other end, and is locked using the locking device in the closed state, and is opened. The city is operated by rotating and opening.

On the other hand, the rotatable insect screen is mainly installed in the porch, because it is disposed in the interior side of the door to be installed so as to rotate toward the interior when opening to avoid interference with the door.

Therefore, according to the conventional rotary insect screen, if an obstacle such as a shoe is placed in the radius of the insect insect, the opening operation is hindered, and as a result, it takes up a lot of interior space of the entrance for smooth opening and closing operation of the insect screen. There is a problem that the space that the user enters and decreases causes inconvenience.

In order to solve this problem of the rotating screen, a folding screen has been devised.

As shown in FIG. 1, the conventional rotary folding insect screen 10 includes an inner door frame 12 and an outer door frame 13 having a frame shape connected to each other and supporting the mesh body 101. One end of the door frame 12 is rotatably connected to the side door frame 7, and the outer door frame 12 and the inner door frame 13 are hinged to each other to be folded together.
