Description

[Detailed explanation of the idea] The present invention relates to an improvement of a grill shutter.

Conventional grill shutters were constructed from pipes and used a winding method.

With this method, the diameter of the roll was large and required a lot of space for storage.

The present invention improves this so that it can be folded into place.

Embodiments will be described below with reference to the accompanying drawings.

Referring to Figure 1, 1 is the horizontal bar of the grill shutter, 2
is a link plate that connects the upper and lower horizontal bars 1, 1 in a foldable manner.

The link plates 2 are a set of two and are assembled so as to form a figure eight shape when the grille shutter is opened.

2 and 3 are enlarged perspective views showing how the horizontal bars 1, 1 and the link plate 2 are engaged.

Rectangular openings 3 and 3' are bored in the horizontal beam 1 at predetermined intervals for each pair of link plates 2 to be attached in a figure-eight shape.

A lower cylindrical portion 4 is provided at the lower end of the link plate 2, and the base of the lower cylindrical portion 4 forms a constricted portion 5, which fits into the opening 3'.

Reference numeral 6 denotes an upper cylindrical portion provided at the upper end of the link plate 2, which has the same width as the opening 3.

A link rod 7 is inserted into the upper cylindrical portion 6 to prevent the link plate 2 from separating from the horizontal beam 1.

Therefore, it is natural that the link rod 7 is larger than the width of the aperture 3 or the upper cylindrical part 6.

With the above configuration, in order to configure the grill shutter, the lower cylindrical portions 4 of the two link plates 2 are placed opposite to each other in the openings 3' of the four openings 3 and 3' of each horizontal bar. After hooking it up, the upper cylindrical part 6 is inserted into the opening 3 of the horizontal bar 1 located above it, and the link rod 7 is inserted from the side of the horizontal bar 1 and fixed.

The grille shutter can be easily assembled by performing the same operation for each opening.

Since the grill shutter assembled in this way can be folded as shown in Figure 4, a seat plate 8 (Figures 5 and 6) is provided further below the horizontal bar 1 at the lowest end, and a seat plate 8 (Figures 5 and 6) is provided for hanging. It can be opened and closed by attaching the rope 9 and connecting the upper end of the rope to a winding device 10 attached to the ceiling.

5 and 6 show the method of opening and closing the grill shutter. In FIG. 5, the grill shutter is folded and lifted by a rope 9, and opened and closed by hanging.

In this case, the grill shutter is guided by the guide rail 11 and opened and closed vertically.

In the case of Fig. 6, opening and closing with the rope 9 is the same as in the case of Fig. 5, but in this case, when opening the grille shutter, the upper part of the grille shutter is bent by almost 90 degrees on the ceiling by a guide rail. I am letting you know.

Figure 7 shows the structure of the grille shutter to make it easier to be guided by the curved guide rail 12.
It is connected at an eccentric position.

As described above, according to the present invention, since it is a folding type, it is possible to reduce the amount of storage required when the grille shutter is closed.

Furthermore, by changing the design of the link board 2 (see Fig. 7), various variations are possible.

Furthermore, the storage is placed in a curved manner under the eaves (Figure 6).
Since it can be stored vertically (Fig. 5), it can also be used as a louver by widening the width of the horizontal bar.

In addition, by appropriately selecting the cross-sectional shape of the horizontal beam, problems regarding strength can be easily solved, and a wide variety of designs are possible.

Figure 8 shows a shorter horizontal link board 2 between the upper and lower horizontal bars.
8, and a link board is attached between this and the upper and lower horizontal bars to make it foldable.Although the structure is more complicated than the diagonal example, it changes the shape of the short horizontal link board. By doing this, you can make the design effect even more effective.

[Brief explanation of the drawing]

Fig. 1 is a partial front view of the grille shutter, Fig. 2 is a perspective view showing how the horizontal beam and link plate are connected, Fig. 3 is a side sectional view of the same, and Fig. 4 shows the grille shutter in a folded state. show. Figure 5 is a side view of the grille shutter placed vertically inside the bottom, Figure 6 is a side view of the grille shutter installed vertically guided inside the bottom, and Figure 7 is a side view of the grille shutter with a different shape of the link plate. FIG. 8 shows an example in which a short horizontal link plate is provided. In the diagram: 1...Horizontal beam, 2, 2a...

Claims (1)

[Scope of utility model registration request] A link plate 2 having a narrow upper cylindrical part 6 at the upper end and a wider lower circular part 4 at the lower end, and a link board 2 having a width approximately equal to the upper cylindrical part 6 through which the upper cylindrical part 6 is inserted. The lower cylindrical part 4 is made up of a horizontal bar 1 in which pairs of horizontally long rectangular openings 3' are symmetrically drilled at a predetermined interval to allow the lower cylindrical part 4 to pass through. The grille shutter is constructed by inserting the upper cylindrical part 6 into the opening 3 after inserting the upper cylindrical part 4 into the opening 3' and connecting them with a link rod 7.
