Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a corrugated board for blindfolding, which is attached to windows, balconies, etc. of buildings as a blindfold.

[Prior Art] Conventionally, as this type of corrugated plate for blindfolding, for example, as described in Japanese Utility Model Application Publication No. 153714/1983,
It is known to have a wavy cross section with repeated trapezoidal irregularities. Such corrugated sheets have greater bending strength than those in the form of a flat plate, and when stacking a large number of corrugated sheets for packaging etc., it is difficult to stack them one after another with their uneven surfaces fitting together. However, since the above-mentioned conventional corrugated sheet has sloped side walls in the uneven portion, there is a risk that the side walls may be deformed when a force perpendicular to the sheet surface or a large bending force is applied. However, if it was necessary to increase the bending strength, the thickness of the corrugated sheet had to be increased.

[Problems to be Solved by the Invention] An object of the present invention is to increase the bending strength of the corrugated sheet without increasing its thickness.

[Means for Solving the Problems] In order to solve the above problems, the corrugated plate of the present invention is made of a translucent synthetic resin and is formed into a corrugated cross-sectional shape with repeated square groove-like unevenness. One side wall of the square groove is an inclined wall that extends outward, and the other side wall is a vertical wall that extends perpendicularly to the plate surface. A large number of protrusions are formed on the parts to prevent see-through, and the square grooves are turned sideways and the slanted walls of the square grooves facing the outdoor side are grooved in the mounting frame for attaching to windows or balconies of buildings. It is characterized by being attached to the lower side of the.

[Function] One side wall of the square groove is an inclined wall that extends outward, and the other side wall is a vertical wall that extends perpendicularly to the plate surface, so that the force perpendicular to the corrugated plate surface and the wave The support strength provided by the vertical walls is extremely strong against the force that attempts to bend the plate in a direction intersecting the square grooves, and the corrugated plate does not undergo deformation such as crushing or bending.

Furthermore, although the side walls of the square grooves form vertical walls, a plurality of corrugated plates can be stacked on top of each other with their concave and convex portions fitting together.

Furthermore, since the corrugated plate is placed horizontally and the slanted wall of the square groove facing the outdoor side is placed below the groove when attached to the mounting frame, even if rainwater hits the slanted wall, it will not be affected. Rainwater immediately flows down along the slope and does not accumulate on the sloped wall together with trash.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a blindfold panel formed using a corrugated sheet. In the figure, 1 denotes the corrugated sheet, and 2 denotes a mounting frame 2 that supports the corrugated sheet 1. As shown in FIG.

As is clear from FIG. 2, the corrugated plate 1 is made of a colorless transparent or colored transparent synthetic resin and is formed into a corrugated cross section with repeated irregularities consisting of square grooves 3a and 3b. , 3b is an inclined wall 4 that extends outward, and the other side wall is a vertical wall 5 that extends perpendicularly to the plate surface, and the inner surfaces of the square grooves 3a and 3b are
The part inside the middle part of both side walls, that is, the bottom wall 6
A large number of protrusions 7 are formed in the axial direction of the square grooves 3a and 3b to prevent viewing through the inclined wall 4 and the vertical wall 5 at a portion closer to the bottom wall 6 than the intermediate portion thereof. Although the protrusion 7 has a semicircular cross section in the illustrated embodiment, it can have any shape such as a triangle or trapezoid. The square grooves 3a and 3b are formed in the same number on both sides of the corrugated sheet 1 in a perfect shape surrounded by the sloped wall 4 and the vertical wall 5, and the sloped wall 4 is formed at both ends of the corrugated sheet 1. One incomplete square groove 9a, 9b surrounded by a small vertical wall 8 having a low height is formed, and as shown in FIG. When used in combination, by slightly overlapping the ends of both corrugated plates 1, 1, a ventilation gap 10 is maintained between the small vertical walls 8, 8, and the square grooves 3a, 3b are formed as a whole panel. The corrugated plates 1, 1 can be connected as if the unevenness is repeated.

In this way, if one of the side walls of the square grooves 3a, 3b is a vertical wall 5 perpendicular to the plate surface, the force acting perpendicularly to the corrugated plate surface and the corrugated plate 1 Since the supporting strength of the vertical wall 5 is extremely large against the acting force that attempts to bend the corrugated sheet 1 in a direction intersecting with the corrugated sheet 1, the corrugated sheet 1 is unlikely to be deformed such as being crushed or bent. Moreover, since only one side wall of the square grooves 3a and 3b is the vertical wall 5, when the corrugated sheets 1 are packed or transported, it is difficult to arrange the corrugated sheets 1 in a state in which the corrugated sheets 1 are fitted with their concave and convex portions. It can be accumulated. Furthermore, protrusions 7 are provided on the inner surfaces of the square grooves 3a and 3b.
By forming the corrugated plate 1, even if the corrugated plate 1 comes into contact with a foreign object, the protrusion 7 will not come into contact with the foreign object, so the protrusion 7 will not be rubbed.

On the other hand, the mounting frame 2 has upper and lower horizontal frame members 15, 1
6, left and right vertical frame members 17, 17, and a middle frame member 18 in the center.A plurality of corrugated plates 1 are placed on both sides of the middle frame member 18, respectively, with square grooves 3a, 3b facing horizontally. It is attached to the top and bottom. To explain in more detail, as shown in FIGS. 2 and 3, upper and lower horizontal frame members 15, 16 and left and right vertical frame members 17, 17
has grooves 15a, 16a, 17a on each inner surface for fitting the ends of the corrugated sheet 1, and a mounting rail 15b for attaching to a window, balcony, etc. with an appropriate connecting fitting on the back side. 16
b, 17b, and has an H-shaped cross section.
has grooves 18a on both sides thereof into which the side ends of the corrugated sheet 1 fit, and the corrugated sheet 1 is arranged so that the vertical walls 5 of the square grooves 3a facing toward the indoor side are at the bottom. and arrange it horizontally, and attach the ends of each frame material 15, 1
It fits into the grooves 6, 17, and 18, and is screwed to the frame material at the required position. Therefore, on the outdoor side, the inclined wall 4 of the corrugated sheet 1 is located below the square groove 3b, and even if rainwater or the like hits the inclined wall 4, the rainwater or the like will immediately flow along the slope. It will not flow down and stay on the inclined wall 4 together with dirt and the like.

The thus formed blindfold panel is used by being attached to a window, balcony, etc. by appropriate means.
While maintaining good light transmittance due to the synthetic resin and good ventilation through the gap 10, the unevenness formed by the square grooves 3a and 3b and the protrusion 7 prevent see-through.

In addition, the size of the above-mentioned blindfold panel, that is, the middle frame material 1
It goes without saying that the number of 8 and the number of corrugated plates to be attached can be set as appropriate depending on the object to which the panel is attached.

[Effect of the invention] As described above, according to the invention, one side wall of the square groove constituting the corrugated cross section is an inclined wall that extends outward, and the other side wall is made perpendicular to the plate surface. Since the extending vertical wall is used, the supporting strength of the vertical wall can be greatly increased against a force perpendicular to the surface of the corrugated sheet and a force that attempts to bend the corrugated sheet in a direction intersecting the square groove. Thereby, deformation such as crushing or bending of the corrugated plate can be reliably prevented.

In addition, since only one side wall of the square groove is a vertical wall, when packing corrugated sheets, it is possible to stack multiple corrugated sheets with their convexes and convexes fitting together, as in the past. can.

Furthermore, when installing the corrugated plate horizontally on the mounting frame, the slanted wall of the square groove facing the outdoor side is positioned below the groove, so that even if rainwater hits the slanted wall, the rainwater will not flow away. It immediately flows down the slope,
There is no accumulation on the inclined wall together with dirt and the like, and therefore the corrugated sheet is less likely to become dirty.
