Next, the operation of the present invention (assembly, opening / closing of the shutter plate) will be described.

First, the assembly will be described. A support bar is attached to a frame body which is framed and provided with a vinyl locking frame. For example, in the width direction of the frame body (the direction orthogonal to the mounting direction of the shutter plate), the frame bodies are mounted at inner positions at intervals of 1: 2: 1 through welding or fitting.

After that, the shutter plate mounting metal fittings to which the shutter plates are mounted are pivotally attached to the pivoting piece portions of the at least two supporting bars attached. Perform the above pivoting work for each shutter plate . By this
In addition , several shutter plates are swingably attached to each support bar, and each shutter plate is swingable (opened and closed) almost simultaneously through the interlocking plate already attached. Has become. Of course, the interlocking plate may be formed after each shutter plate is attached. As described above, the shutter product is finished by framing the shutter.

The finished shutter is shipped as a product (commodity), and for example, one or a plurality of shutters for ventilation are mounted (mounted) on a side wall of a house or the like. Specifically, it is installed between the shutter mounting frames (pillars and horizontal boards) of the house, and via the vinyl mounting member of the frame,
This shutter is covered with vinyl for house construction. Therefore, the fan (or drive device) is operated, and the shutter plates are swung counterclockwise by wind pressure, or via the link mechanism and the connecting bar, and by the lowering of the interlocking plate (not limited). As a result, the shutter plate is opened (see FIG. 3), and the opened base ends of the shutter plates are abutted against the shoulder surfaces of the pivoting pieces of the support bar to be held in a substantially horizontal state. After that, when the shutter plates are closed, each shutter plate swings in the clockwise direction through the stop of the fan or the operation of the driving device, the link mechanism and the connecting bar, and the lift of the interlocking plate (not limited). However, the back surface of each shutter plate (this back surface through the shutter plate mounting metal fittings, which will be described later) is attached to the tilt stable surface of each pivotal piece of the support bar. The external pressure applied to each shutter plate of this support bar can be dealt with.

In particular, at least two lines are provided at predetermined positions on the frame.
Since the support bars are provided, as described above, through the inclined stable surfaces of the pivot piece portion of the support bar, each shutter plate both sides inside is supported, during its closure, by external pressure It has a structure that does not bend and has sufficient pressure resistance.
