Abstract

PROBLEM TO BE SOLVED: To facilitate housing a rain shutter into a door storage case by connecting adjacent rain shutter doors by a U-shaped magnet through iron plates fitted to the rain shutter doors. SOLUTION: Magnets are mounted on the internal side face and front end faces of a U-shaped sectional rain shutter door coupler 1 consisting of a metal, etc. An iron plate 4 is set up onto the vertical frames of the rain shutter doors, and iron plates 5 are fitted onto rain shutter door plates. When the rain shutter doors are closed, couplers 1 are attached magnetically onto the iron plates 4 of the second and subsequent rain gutter doors, and each rain shutter door is brought into a connected state and unified. When the rain shutter doors are opened, each rain shutter door is pulled to the place of a door storage case, and housed successively into the door storage case while the couplers 1 are removed and attracted magnetically to the iron plate 5. Accordingly, when the rain shutter doors are opened, the rain shutter doors can be housed in the door storage case at a place near to the door storage case without movement on the front sides of the rain shutter doors and pushing against the door storage case side of the rain shutter doors, and the couplers can be mounted and demounted easily by single operation.

Description

Description: TECHNICAL FIELD The present invention relates to a U-shaped shutter door coupler which can be removed with one touch by using a magnet. Conventionally, when the shutter was opened, it was possible to pull by hand the second sheet near the door pocket, but the third and subsequent shutters could not be reached. Therefore, in order to open the third and subsequent shutters, it is necessary to turn to the front side and push the shutter to the door pocket side, which is inconvenient. The present invention is intended to eliminate this inconvenience. By connecting the second and subsequent shutters with a coupler as shown in FIG. 2 when closing the door, the third and subsequent shutters can be pulled on the spot when the door is opened. The shutter door coupler of the present invention comprises a coupler and an iron plate.
1) The coupler (1) is made of metal or synthetic resin.

It is only necessary to have the strength to pull the connected shutters.

2) The inner surface (2) of the coupler is a magnet.

It plays the role of sticking to the iron plate attached to the shutter frame (two or three sides).

3) Iron plate (4) to be attached to the shutter frame. The magnet (2) of the coupler serves to attach.

4) The tip surface of the coupler is (3) a magnet.

When not using a coupler (when keeping a shutter in a door pocket)
In addition, it serves to attach it to an iron plate attached to a shutter plate.

6) Iron plate to be attached to the shutter plate (5) The magnet of the coupler serves to attach.

The magnet and the iron plate in the above description serve to attach the coupler to the shutter, and the positions of the magnet and the iron plate may be reversed.
