DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door for a doorway and a ventilation panel provided in a part of a building.

[0002]

2. Description of the Related Art Ventilation openings are formed in doors and parts of buildings so that air can enter and exit. In this case, a vent is provided to prevent the inside from being seen from the outside. FIG. 7 shows a conventionally used ventilation panel. By fitting the panel into a predetermined ventilation port, ventilation can be performed so that the inside cannot be seen. That is, the ventilation panel is parallel at a certain interval with a plurality of blades inclined obliquely downward.

[0003] Accordingly, a predetermined space is formed between the blades, and air can enter and exit through this space.
If viewed from diagonally below and parallel to the blades, they will be visible from the space, but simply from the front, the blades overlap each other and cannot be seen through. Incidentally, such a ventilation panel is a molded product using a resin, and panels of the same size and the same shape are manufactured in large numbers. The ventilation panel is a standardized member and must be based on the size of the ventilation panel in the manufacture of the door and in the design of the building. May be greatly restricted. On the other hand, the production cost is relatively high because a molding die is required.

Therefore, there is also known a panel in which a frame of a predetermined size is manufactured without being integrally formed as a ventilation panel as shown in FIG. 1 and a blade is fitted into the frame. Therefore,
The necessary number of blades are fitted into the frame to create a properly sized ventilation panel. However, in this case, grooves for fitting the blades must be formed diagonally on both side rails of the frame, and special grooved side rails are required. Also in this case, since the side rail is injection-molded, a mold is required, which results in an increase in cost.

FIG. 8 shows another specific example of a conventional ventilation panel. This panel is formed by punching and bending a single flat plate to form a plurality of blades, but a gap h remains between each of the blades. Although this panel is easier to manufacture than the panel shown in FIG. 7, the inside can be seen from this gap h, and the function as a ventilation panel cannot be sufficiently performed.

[0006]

As described above, the conventional ventilation panel has the above-mentioned problems. The problems to be solved by the present invention are these problems. To provide a ventilation panel which is easy to manufacture and can accommodate a ventilation port of any size.

[0007]

The ventilation panel according to the present invention is constituted by arranging elongated plate members in the plate thickness direction.
The plate members are arranged in parallel by partially overlapping adjacent plate members. The thickness of the overlapped portion is halved so that the plate material partially overlaps, and is bent or curved in a convex shape in the longitudinal direction except for both end portions thereof, and sometimes twisted. Therefore, when arranging plate members having such a shape, a space through which air flows is formed between the plate members, and functions as a ventilation panel.

[0008] When viewed from the front, the plate members are partially closed and arranged completely, so that they are completely closed and the inside is not visible. Also, since the overlapped portion of each plate is half in thickness, the thickness of the plate is obtained by overlapping two sheets. Therefore, the respective plate members are arranged by fitting into the grooves of the side rails, and the grooves are linear grooves having a constant width. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0009]

FIG. 1 shows a concrete example of a plate constituting a ventilation panel according to the present invention. Are arranged in the width direction to form a ventilation panel. The ventilation panels arranged and arranged allow air to pass therethrough and can be seen through from between the plate materials 1, 1,. There is no structure. As is clear from the figure, the cross section of the plate material 1 is cut in the upper and lower portions and is half in thickness. That is,
The thickness T of the plate material is twice the thickness t of the cutout portion, and the thickness becomes T when another plate material overlaps this portion.

The plate 1 has a shape protruding toward the surface except for both sides thereof. That is, fastening portions 3 are formed on both sides of the convex portion 2, and the fastening portions 3 are formed.
3 is fitted and attached to a groove provided in the frame side bar, but the fastening portion 3 can appropriately adjust the length of the plate material 1 by cutting off the tip. The plate material 1 is formed in a shape provided with long fastening portions 3, 3 and can be applied to ventilation holes of any size by cutting and using the fastening portions 3, 3.

The plate members 1, 1,... Are arranged in the vertical direction. However, the overlapped portion 4 which has been cut away and thinned is overlapped with the overlapped portion of another adjacent plate member 1. Arrange. The overlapping portions 4 each having a thickness of と な り overlap each other to have the same thickness, and all the fastening portions 3 have a thickness T. However, the arranged plate materials 1, 1,... Face in opposite directions, and the convex portions 2, 2,.

FIG. 2 shows a case where four plate members 1a, 1b... Are arranged. In this manner, the respective plate members 1a, 1b... Are arranged such that their overlapping portions 4, 4,... Are overlapped, and the convex portion 2a of the plate member 1a is moved rearward in FIG.
b is located on the front side and sequentially arranged on the opposite side. Therefore,
Spaces 5, 5,... Through which air can pass are formed between the protruding portions 2a, 2b,. However, since the plate members 1a, 1b,... Are partially overlapped and arranged, they cannot be seen through from the front.

FIG. 3 shows a case in which the plate members 1, 1,... The frame 6 is composed of an upper beam 7, a lower beam 8, and both side beams 9, 9, and has a horizontal dimension L and a vertical dimension H. .. Are fitted into the frame 6, and the plate 1 has such a length that both the fastening portions 3, 3 are cut and can be fitted into the grooves of the side rails 9, 9. In the height direction, the required number of sheets are fitted and arranged in the grooves of the side rails 9, 9 so that there is no gap between the upper and lower rails 7, 8.

Since the height of the plate 1 is fixed, it cannot be arranged so as to abut on the upper and lower rails 7 and 8, and is adjusted by the overlapping section 4 for that purpose. That is, another plate material 1 is placed on the bottom 10 of the cutout portion of the overlapping portion 4.
The plate material 1 is placed by placing a spacer on the
... The interval (pitch) between them increases.

FIG. 4 shows another embodiment of the ventilation panel according to the present invention. This is the same as the case where the ventilation panel shown in FIG. 3 is additionally provided, and the frame 11 is provided with a middle bar 12 between both side bars 9, 9. FIG. 5 shows another embodiment of the plate 13. The plate 13 has a twisted shape except for the fastening portions 14 at both ends, and the convex portion 15 is inclined with respect to the fastening portion 14. Of course, the upper and lower ends form notched overlapping portions.

FIG. 6 shows a case where the above-mentioned plate members 13, 13... Are arranged. A space is formed between the inclined convex portions 15, 15,. Function. The shape of the plate material constituting the ventilation panel of the present invention is not limited to the case shown in FIGS. 1 and 5, but may be any other suitable shape. As described above, the ventilation panel of the present invention is configured by fitting the plate material into the frame, and can obtain the following effects.

[0017]

According to the present invention, a plurality of plate members are fitted into a frame, and a ventilation panel having an appropriate size can be obtained according to the number of the plate members used. The plate is formed with fastening portions on both sides of the convex portion protruding to the front side, and if each plate is arranged by overlapping the overlapping portion,
A space through which air flows is formed between the plate members, and can function as a ventilation panel. By adjusting the number of the plate members, a ventilation panel having an arbitrary size can be manufactured.

Further, since the respective plate members are arranged by overlapping the overlapped portions, the inside cannot be seen through from between the plate members.
Further, by adjusting the amount of overlap in the overlapping portion, the frame can be arranged without gaps between the upper and lower rails of the frame, and the size of the ventilation port is a versatile ventilation panel. On the other hand, because it can be manufactured by forming a plate material of a predetermined size and arranging and combining the plate materials,
Manufacturing costs are also reduced.
