Description

[Detailed Description of the Invention] This invention relates to a slat that forms the curtain of a performance shutter.

When conventional shutters are installed in the outdoor opening of a building, the inside of the shutter is completely blocked off from the outdoors, resulting in a closed room and pitch darkness, and the air in the room is not ventilated. There is.

Due to these characteristics, conventionally, when performing work that requires daylighting and ventilation in a room adjacent to a winding shutter, the shutter was half-open each time. In such cases, measures such as drilling window holes at key points in the slats were taken.

However, since the slats of the slats are made of thin sheet steel that is long in the lateral direction because they need to be wound around the outer periphery of the take-up shaft installed inside the shutter case, a window hole is drilled in the middle of the slats. However, with these countermeasures, not only is there a limit to the size of the window hole, but there are also problems with the strength of the curtain, and furthermore, the manufacturing process of the shutter becomes troublesome, and the cut of the window hole may cause danger to people or objects. There were problems such as the risk of being injured.

The present invention was made in order to solve the above problems, and the purpose of the present invention is to have a slat curtain that can be easily assembled to a slat curtain in a display shutter, and to have sufficient translucency and air permeability. However, it is an object of the present invention to provide a slat for a winding shutter that does not interfere with the raising operation of the curtain.

Hereinafter, the present invention will be explained based on an illustrated embodiment.

As shown in FIGS. 1 and 2, a plurality of slats 2 and 3 forming a slat curtain 1 in a winding shutter that is wound around the outer periphery of a winding shaft installed in an upper shutter case are illuminated. The slats 3 have a desired height suitable for ventilation, etc., and have translucency or air permeability (translucent in the case shown). This will be explained using Figure 3.

This slat 3 is a prefabricated slat, and its constituent members include an upper plate 4 on the upper edge of which is formed a fold 4a that engages with the adjacent slat 2, and a similar fold 5a formed on the lower edge. It consists of various members: a lower plate 5, an intermediate panel 6 held between both plates 4 and 5, and an appropriate number of connecting plates 7 that integrally connect both plates 4 and 5 at appropriate locations. .

Therefore, the upper plate 4 and the lower plate 5 have the same shape as the upper half and lower half of the other slats 2, and the folded 4
The parts continuous to a and 5a are bent at a predetermined angle in the same direction on the front or back side of the slats, and the inner edges of each are provided with U-shaped grooves into which the upper and lower edges of the intermediate panel 6 fit. The clamping grooves 4a and 5b are bent in a protruding manner in the same direction as the above-mentioned bending direction.

Note that, like the other slats 2, these upper plates 4 and lower plates 5 are made of iron, aluminum, synthetic resin, or the like by roll molding, extrusion molding, or the like.

Next, the intermediate panel 6 is a rectangular transparent or translucent glass plate or a resin plate, and the panel 6 is held in the clamping grooves 4b and 5b at the top and bottom, and the width of the panel 6 is The size can be freely set according to the desired amount of daylight.

The joint plate 7 is a plate piece made of the same material as the upper and lower plates 4 and 5, and is attached with screws 8 ( (illustrated), is fixed to both plates 4, 5 by rivets, adhesives, etc., and connects both plates 4.5.

Note that even if this joint plate 7 is fixedly installed on the front side of the slat 3,
There are no functional problems.

If the curtain 1 is constructed by mixing the curtain slats 3 formed in this way, external light will enter the room through the panel 6 of the slats 3, so it is possible to work indoors even with the shutter 7 closed. .

In addition, if you change the width, translucency, and shape of the translucent surface of the intermediate panel and prepare many types of intermediate panels and their joint plates in advance, you can complete the required assembly process with the same number of man-hours as the conventional assembly process. It is possible to assemble a shutter that adapts to the natural lighting characteristics.

By the way, the above-mentioned embodiment is a form of slat formation for the purpose of daylighting, but when the purpose is ventilation, the intermediate panel is made of the same material as the upper and lower plates 4 and 5, and A window hole of an appropriate shape may be punched in an appropriate place, or a suitable glass plate or the like may be used in place of the intermediate panel.Furthermore, an intermediate panel with both translucency and breathability may be provided. As a result, a multi-purpose and various types of shutters can be obtained.

In addition, as for the manner in which the intermediate panel is held, it is possible to use an appropriate conventional means in place of the above-mentioned shape. For example, as shown in FIG. 4, the upper and lower edges of the intermediate panel 8 are It is also possible to insert and fix the frame 9 into the holding grooves of the upper and lower plates 10 and 11, or by folding the upper and lower edges of the intermediate panel 12, as shown in FIG.
It is also possible to form a frame portion 12a for attachment, and insert and fix the frame portion 12a into the holding grooves 13a and 14a formed by folding the inner edges of the upper and lower plates 13 and 14 in opposite vertical directions. Furthermore, if sufficient slat strength can be obtained by the fixing means, the use of joint plates becomes unnecessary.

As described above, according to the slats of the display shutter according to the present invention, the slats having translucency and air permeability are mixed in the coupled slats of the shutter curtain, so that the assembly process of the shutter is not complicated. Therefore, it becomes possible to construct a shutter with desired lighting and ventilation properties, and this has the effect of improving the practicality of the roll-up shutter.

Further, according to the shutter slat according to the present invention, at least one of the many slats forming the slat curtain is bonded to the upper and lower plates formed of horizontally long thin plates and between the upper and lower plates. The outer edges of the upper and lower plates are bent in the same direction on the front or back side of the slats, and the inner edges of the upper and lower plates are continuous with the folds. It is bent into a protruding shape in the same direction as the part to form a clamping groove.
Since the upper lower edge of the intermediate panel is fitted between the protruding clamping grooves and clamped, the intermediate panel is housed in a recess on the front or back surface of the slat formed of a thin plate material. Therefore, the intermediate panel does not get in the way when raising or lowering the slat curtain, and this type of slat 1~ can be used as a part of the curtain of the winding shutter without any hindrance and does not cause noise or noise. This has an excellent practical effect in that there is no occurrence of.
