Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a plate material for a ventilation shutter having a ventilation function.

[Problems to be solved by the prior art and the invention] Conventionally, in order to provide ventilation to shutters, the methods shown in Fig. 7,
As shown in FIG. 8, both ends of the shutter blade a, which has locking pins b formed at both ends, are inserted into holes d formed in the left and right side frames c of the window frame, and the locking pins passing through the holes d are inserted. It is known that the pin b is bent to assemble the window so that it cannot be removed, and the thus assembled louver window is fitted into the shutter. However, this device has a large number of parts, and the assembly work of the louver blade b is troublesome and troublesome, requiring a large amount of assembly time and man-hours.

Therefore, as shown in Japanese Utility Model Application Publication No. 51-32938, plate surface parts and slits are alternately formed in the vertical direction at a predetermined pitch on a flat metal plate, and the lower end of the upper plate surface part faces outdoors, and the lower end of the lower plate surface part It is proposed that the plate material be bent into a serrated cross-section so that the upper end is located outdoors and the slit portion forms a step-like horizontal surface, thereby creating a plate material for ventilation shutters that does not require the installation of a glazed window as described above. . However, in this case, the slits remain wide open all the time, so outside air directly enters the room through the slits, resulting in a loss of heat retention in the winter, and the need for an insect screen to be installed. When attempting to prevent the invasion of insects, consideration must be given to the installation of a separate insect screen attachment member, and this cannot be adopted immediately.

[Means for solving the problem] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a plate material for ventilation shutters that can eliminate these drawbacks. The plate surface portions and slits are alternately formed in the vertical direction at a predetermined pitch, and a pair of folded pieces are provided at the periphery of each slit so as to continue from the upper and lower plate surface portions, respectively. The metal plate on which the surface portion and slits are formed is placed so that the lower end of the upper plate surface portion is located outdoors, the upper end of the lower plate surface portion is located indoors, and the slit portion forms a stepped horizontal surface and is located between the upper and lower plate surfaces. In order to make a plate material for a ventilation storm door by bending it into a serrated cross-section, the folded piece continuing from the upper plate surface part of the pair of folded pieces is folded back so as to face the indoor side surface of the upper plate surface part, and The folded pieces continuing from the side plate surface are folded back and bent so as to face the indoor side surface of the lower plate surface, and each folded piece is configured as a hook-like locking piece. A locking hook portion is formed on both side edges of the cover member and is configured to removably lock onto the locking piece, so that the slit portion is blocked by the locking piece via the removable cover member. This is a characteristic feature.

With this configuration, the present invention allows the cover to be easily attached to the slit portion, even though the slit portion is formed in the shutter plate material itself.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes a plate material for a ventilation shutter having a sawtooth cross section, and is formed in the following manner. In other words, slit parts 2 with a predetermined width left at both ends on a metal plate A wound into a coil shape, and plate surface parts 3 with a blind plate shape are alternately repeated in the vertical direction of the shutter. to form. Here, the slit portion 2 may be a one-hole type that is approximately the width of the coil as shown in FIG. 2, or a two-hole type or a three-hole type as shown in FIGS. 9A and 9B. In either case, folded pieces 2a are formed on the periphery of a pair of long sides of the slit portion 2 so as to continue from the adjacent plate surface portions 3, respectively. Next, the metal plate A on which the slit portion 2 and the plate surface portion 3 are formed is passed through a forming roll to the upper plate surface portion 3.
The lower end is located on the outdoor side, the upper end of the lower plate surface part 3 is located on the indoor side, and the slit part 2 is located on the stepped horizontal surface part 1.
The sheet material is bent to have a serrated cross-section so as to be located between the upper and lower plate surfaces 3, thereby forming a plate material for a ventilation shutter.In the present invention, a folded piece 2a is further folded back into a hook shape. ing.

In other words, the slit portion 2 has a pair of folded pieces 2a.
However, the folded piece 2a continuing from the upper plate surface part 3 is folded back to face the indoor side surface of the upper plate surface part 3, and the folded piece 2a continuing from the lower plate surface part 3 is folded back so as to face the indoor side surface of the upper plate surface part 3. 3, so that both folded pieces 2a are configured as hook-shaped locking pieces that are folded back toward the indoor side.

Further, reference numeral 5 denotes an insect repellent net which is an embodiment of a cover member for blocking the opened slit portion 2, and the insect repellent net 5 includes mesh frames 5a, 5b made of extruded aluminum material, and the mesh frames 5a, 5b. The net frame 5 is composed of a net material 4 whose both side edges are inserted and fixed into the net insertion grooves 5d formed in each of the net frames 5b and 5b.
A locking hook portion 5c is further formed on a and 5b. The insect screen 5 is configured such that the locking hook portion 5c is removably locked to the folded piece 2a which has become a locking piece from the indoor side, so that the slit portion 2 can be blocked off in a ventilation and insect-proof state. It's getting old. Incidentally, the procedure for attaching the insect screen 5 is to first lock the locking hooks 5c to the folded pieces 2a on the lower plate surface 3 side, and then attach the hooks 5c to the folded pieces 2a on the upper plate surface 3 side using the elastic deformation of the net material 4. It is only necessary to lock the locking hook portion 5c in the position.

In addition, when it is desired to block the ventilation from the slit portion 2 in winter or summer, a cover 6 in the form of a blind plate as shown in FIG. It is sufficient to manufacture it in advance and attach it to the slit portion 2 in place of the insect screen 5 as needed. In this case as well, the locking hooks 5 are attached to the upper and lower edges of the cover 6.
A locking hook portion 6a having the same shape as c is provided.

In the embodiment of the present invention constructed as described above, the slit portions 2 and the plate surface portions 3 are alternately and repeatedly formed on the metal plate A, and the slit portions 2 form a stepped horizontal surface. By bending the metal plate A so that the lower end of the side plate surface part 3 is located on the outdoor side and the upper end of the lower side plate surface part 3 is located on the indoor side, the slit part 2 for ventilation can be easily formed. There is no need for a glass window like in the past.

When it is desired to block this slit portion 2 with an insect repellent net 5 or a blind plate-like cover 6, the locking hook portions 5d and 6a provided on the insect repellent net 5 and the cover 6 are hook-shaped toward the indoor side. It can be easily fixed by locking the folded piece 2a which has been folded back to become a locking piece. Moreover, these attachment/detachment operations can be easily performed from indoors. As a result,
It is simple and easy to attach the cover member for blocking the slit portion 2, and there is no need to separately prepare members for attaching these cover members to the shutter board side and attach them one by one. A locking piece for attaching a cover member can be formed by an extremely simple structure in which a pair of folded pieces 2a extending from each of the upper and lower plate portions 3 are folded back toward the indoor side. Furthermore, the folded piece 2a can also reinforce the slit portion 2, so that even if the slit portion 2 is formed in a single plate, there will be no problem in terms of strength.

[Operations and Effects] In summary, the present invention is constructed as described above, and the shutter plate itself is provided with a slit portion having a ventilation function, so that it is not necessary to install a glass window one by one as in the conventional method. There's no need.

When it is necessary to block this breathable slit part with a cover member such as an insect repellent net or a blind plate-like cover, the locking hook part provided on these cover members can be turned into a hook shape toward the indoor side. By locking the folded piece that has been folded back to become a locking piece, it can be easily fixed from the indoor side. As a result, it is simple and easy to attach cover members to block the slits, and special members for attaching these cover members are prepared separately on the storm door panels, and these can be attached to the shutter panels one by one. The locking piece for attaching the cover member can be made into a locking piece without any trouble and with an extremely simple structure in which the pair of folded pieces continuing from the upper and lower plate surfaces are respectively folded back toward the indoor side. Furthermore, the slit portion can be reinforced by the folded piece, so even if the slit portion is formed in a single plate, there is no problem in terms of strength.
