Description

[Detailed Description of the Invention] The present invention relates to an architectural shutter curtain that constitutes a shutter curtain for an architectural shutter.

Generally, this kind of architectural shutter curtain is
Most are formed by connecting a series of slats that have interlocking joints on both upper and lower edges. However, the above interlock connection part is
Since it has to perform both the supporting function of supporting the weight of the shutter curtain and the rotation function to enable winding, a considerable load is applied each time the shutter curtain is raised and lowered. Not only is it unpleasant to the ear as it rotates in the open position, producing a particularly loud rubbing noise, but it also has the disadvantage that smooth opening and closing operations are hindered by the rubbing, which has become a problem. Therefore, by fitting the core material into the interlock joint and connecting and supporting each adjacent core material through the link material, the supporting action of the interlock joint can be applied to the core material and the link material. There are some methods that try to take care of this problem, but even with this method, the edges of the slats still rub against each other at the interlock joint, so it is impossible to completely eliminate the unpleasant noise caused by the rubbing. This was not possible, and further improvements were needed.

In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing an architectural shutter curtain that can eliminate these drawbacks. In the architectural shutter curtain formed by the above-mentioned construction, the upper edge of each slat is fitted with a core material which is longer than the width of the slat and whose left and right ends protrude from the slat so as to surround substantially the entire periphery of the core material. A fitting and holding part is formed which has a substantially cylindrical shape and protrudes toward the outdoor side from the upper end of the slat plate surface, and each core member protruding from adjacent slats is connected to each other through a link material. On the other hand, the lower edge of each slat has a curved part whose tip faces the upper side plate surface of the adjacent slat from the outdoor side and is curved so as to be applied to the fitting and holding part of the adjacent slat from the outdoor side. It is characterized by the fact that it is formed.

With this configuration, the present invention reliably prevents the occurrence of unpleasant noises during the up/down movement, and also makes the opening/closing operation extremely smooth.

Next, the present invention will be explained in more detail based on an embodiment shown in the drawings. In the drawings, reference numeral 1 denotes a shutter for construction, and the shutter curtain 3 is wound up and down on a winding shaft (not shown) that is rotatably supported in a shutter case 2, and is unwound. As before, the opening is opened and closed by moving up and down. 4 is a guide rail, and 5 is a seat plate.

Reference numeral 6 denotes a slat forming the shutter curtain 3, and the upper edge of the slat 6 is provided with a fitting receptacle that is approximately cylindrical and protrudes toward the outdoor side from the upper end of the slat plate surface. A holding portion 6a is formed, and the fitting and holding portion 6a fits and holds in its center a pipe material 7 which is longer than the width of the slat and whose left and right ends protrude from the slat 6.

Adjacent left and right ends of the pipe material 7 protruding from the slat 6 are connected in a series through link materials 8, thereby forming the shutter curtain 3 of the present invention. The width L of the material 8 is somewhat wider than the thickness R of the slat 6 (L
>R).

On the other hand, the tip of the lower edge of the slat 6 faces the upper side plate surface of the slat adjacent to the lower side from the outdoor side,
Moreover, it is formed into a curved portion 6b that is curved so as to be applied from the outdoor side to the fitting and holding portion 6a of the adjacent slat 6, so that the fitting and holding portion 6a can be engaged and held.

In the embodiment of the present invention constructed as described above, the pipe material 7 fitted and held by each slat 6 is connected and supported via the link material 8, and the self-weight bearing action of the slat 6 is received by the connection structure of the pipe material 7. However, the lower edge of each slat 6 is not interlocked with the slat 6 adjacent to the lower side, but the fitting and holding part of the upper edge of the slat 6 that fits and holds the pipe material 7. 6a is applied from the outdoor side. Therefore, the slat lower edge 6b
can be made almost free to the extent that it is applied from the outside to the adjacent slat 6, and the contact area can be significantly reduced. As a result, unpleasant noises can be avoided when the shutter curtain 3 is raised and lowered. As a result, the relative rotation of the slats 6 becomes extremely smooth, and as a result, the shutter curtain 3 can be moved up and down extremely smoothly.

In this embodiment, the width L of the link material 8 is
is wider than that of slat 6, so shutter case 2 of shutter curtain 3
The slats 6 do not come into direct contact with each other when they are fitted into the guide rail 4.
Since the slats are guided by the slats, the surface of the slats can be effectively prevented from being damaged, which is convenient.

In summary, since the present invention is constructed as described above, the core material fitted and held by each slat is connected and supported via the link material, and the self-weight bearing function of the slat is taken over by the connection structure of the core material. Although the lower edge of each slat is not firmly interlocked with the adjacent slat below, the lower edge of each slat is not tightly interlocked with the upper edge of the slat that fits and holds the core material. It has a curved shape so that it can be applied from the outside. Therefore, the lower edge of the slat can be left almost free to the extent that it is applied from the outdoor side to the adjacent slat, and the contact area can be significantly reduced, and as a result, the vertical and vertical movement of the shutter curtain can be reduced. During operation, it is possible to almost eliminate the generation of unpleasant noises caused by friction between the slats, and the opening/closing operation can be made extremely smooth.
