Description

[Detailed Description of the Invention] This invention relates to a frontage extension structure for an open/close type louver in which the louver is rotated.

An example of the structure of an open/close type louver in which the louver is rotated is as shown in Fig. 1, in which a large number of blades 1 are arranged in parallel.
The mounting shaft 4 of is connected to a drive ratchet 8 via a mounting arm 5, a mounting rod 6, and a connecting rod 7, and the drive ratchet 8 is rotated to cause the mounting rod 6 to reciprocate and maintain the same relative position of each blade. It can be closed or opened.

Note that it is not necessarily necessary to use a drive ratchet to open and close the blades as long as the structure is such that the rod is moved back and forth.

When opened, the retractable louver allows sunlight to be enjoyed, and when closed, it acts as a leak-proof roof, so it is very useful when used, for example, on the roof of a building's eave terrace.

The opening/closing method of the louver in the present invention is not limited to the structure described above.

If the frontage length of the retractable louver is increased beyond a certain level,
As the length increases, the number of blades increases, and as a result, the additional stress generated from each blade due to the wind pressure on the blade increases.
Excessive stress is added to the opening/closing mechanism parts, and as the number of opening/closing mechanism parts and skeletal structures increases, processing errors accumulate resulting in incomplete opening/closing of the blades, instability in strength after roof installation,
Otherwise, it is unsuitable because it causes disadvantages such as increased resistance to opening/closing operations and difficulty in transportation due to increased length of the skeletal structure.

Conventionally, the opening/closing louver had a frontage of 270cm.

Those with rated dimensions such as 360 cm are manufactured, but if you need a wide frontage such as 540 cm or 720C171, for the above-mentioned reasons, it is necessary to install multiple opening/closing louvers of the appropriate size in series. will be carried out.

However, installing multiple retractable louvers next to each other increases costs, increases the number of pillars and impairs the aesthetics, and requires post-treatment to clear out rain between each louver. There's a problem.

The present invention provides a frontage extension structure that solves the problems associated with the above-mentioned continuous installation of openable and closable louvers.

One embodiment of the present invention will be explained based on the drawings. Figure 1 shows a case where two opening/closing louvers are connected, and the head of the left opening/closing louver (the end on which the ratchet is attached) is at the left end. , are integrally attached via a common intermediate post 9 and intermediate beam 1o so that the tail (the end opposite to the ratchet attachment side) is in contact with the tail of the right opening/closing louver.

The opening/closing louver on the right side has the same dimensions as the one on the left side, and is installed so that the opening/closing direction of the blades is the same.

Of course, the left and right sides may have different widths, and the rotation of the blades may be symmetrical rather than parallel, but from the aesthetic point of view, it is better to connect blades with the same width, and the direction of rotation of the blades should also be adjusted according to the sun. It is preferable to run them parallel to each other in order to maintain the same degree of light penetration.

A joint member 11 is attached to cover the intermediate beam 10 that connects the two openable louvers described above.

This joint member 11 is connected to the intermediate column 9.9 as shown in FIG.
The left edge of the joint member 11 is bent downward to form a bent blade engagement side 12 that engages with the left blade. is preferable, and thereby, when the left retractable louver is closed, it engages with the terminal blade 1 to prevent rain from blowing in.

Further, the right side side of the joint member 11 is bent upward to form a trough-like bent blade engagement side 13, such as a U-shape or a V-shape, for example.
When the right side retractable louver is closed, it engages with the blades at the terminal to prevent rain from blowing in, and acts as a drainage gutter.

In addition, in the present invention, at least the bent blade meshing side 13
As long as the left side has a flat plate-like protruding side that covers the bent edge of the left wing instead of the bent engagement side 12, there is no inconvenience in preventing rain from blowing in or draining water.

As shown in the vertical cross-sectional view perpendicular to the intermediate beam 10 in FIG.
The bent blade engaging side 12 and the right bent blade engaging side 13 may be attached separately, or as illustrated in FIGS. 4, 5, and 6, cross-sectional views of other joint member embodiments may be used. As shown in
The joint member 11 itself may be given strength as a structural member of the louver framework, and may also be used as a beam that connects the front and rear intermediate columns.

According to the present invention, it is easy to connect a plurality of retractable louvers, and it is sufficient for rainwater treatment at the connecting joint.

Moreover, during construction, there is no need to increase the number of intermediate supports, allowing the left and right roof to be seen as an integrated roof structure, which is aesthetically pleasing, and has the advantage of avoiding unnecessary increases in cost due to continuous construction.
Shows excellent effect in extending the frontage of retractable louvers.
