Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention is an improvement of a folding horizontal shutter. Specifically, the joint joint located at the folding part of the horizontal pulling shutter is made into a vertically split telescoping type. This invention relates to a folding horizontal shutter that has a split type joint that can be divided at appropriate locations.

[Conventional technology and technical issues to be solved]

As is well known, in recent years, folding horizontal shutters have become popular in place of storm shutters, but when the opening width of such horizontal shutters increases to 3500 mm or more, the weight when transported can exceed 100 kg. It is extremely difficult to transport and handle at the construction site, and it is practically impossible for one person to carry out the installation work, and there have been strong calls for improvements from related companies.

Due to these circumstances, on the one hand, attempts have been made to reduce the weight of the horizontal pull shutter itself in terms of its material;
In order to airtightly close wide openings such as store entrances and exits that are expected to be exposed to strong winds, it is necessary to have the strength to withstand strong wind pressure.
Even if a light metal such as aluminum is used, there are restrictions on reducing the weight from the viewpoint of ensuring strength.

As mentioned above, this invention has a natural limit to reducing the weight of a horizontal pull shutter due to maintaining its strength.
This was done in view of the fact that this had become a bottleneck in installation work, and the shutter pieces that make up the horizontal shutter can be divided at appropriate points, making installation work easy even for one person. The technical problem is to provide a horizontal shutter with good performance.

[Means adopted to solve the problem]

To explain how the present inventor came to solve the above technical problem, firstly, the joint joints located at even numbers from the hanging joint stile are separated from the lintel and sill positions when each shutter piece is folded. Next, even if the joint pieces of the part that separates from the lintel/sill have a split joint structure, there will be no problem with the function of the horizontal shutter, and each shutter piece will be located at an odd numbered position. The idea behind this idea was that since the hanger rail is suspended from the upper part of the joint, it can be easily connected even after each shutter piece is hung.

Therefore, to explain the technical means adopted by the present invention with reference to the attached drawings, a plurality of vertically elongated shutter pieces 1 are connected by joint joints 3 or 4 so as to be foldable in a zigzag manner, and a suspension joint is It is based on the technical premise of a conventionally well-known horizontal pull shutter, which is constructed by slidingly suspending the upper part of the odd-numbered joint 3 from the stile 6 to a hanger rail 10 built on the lintel side. Among the even-numbered joints from the hanging joint frame 6, at least one joint 4 is connected vertically to the female joint piece 41 and the male member 44 fitted to the male joint piece 41. By adopting a split-type joint structure means in which both parts 41 and 44 are removably connected and integrated, the construction is easy to construct, handle, and transport, which satisfies the technical issues mentioned above. They succeeded in developing an excellent and practical folding horizontal pull shutter.

〔Example〕

Hereinafter, the present invention will be explained in more detail based on embodiments shown in the accompanying drawings.

As shown in FIGS. 1 and 2, the horizontal shutter T of this embodiment has vertical shutter pieces 1, 1...
are connected to the suspension frame 5 at the rightmost suspension joint stile 6. The connection between the hanging joint stile 6 and the hanging frame 5 is such that, as shown on the right side of FIG. It has a structure in which it is inserted into the suspension frame 5.
On the other hand, on the doorstop side, the shutter T is provided with a pull stile joint 8.

Furthermore, as shown in Fig. 3, the shutter T is equipped with hanger rollers 9, 9 attached to the upper parts of the odd-numbered joints 3, 3, etc. located from the suspension frame 5, and attached along the lintel material. It is suspended so as to be guided by the rail grooves 10a, 10a of the provided hanger rail 10, and a slider 12 is installed at the bottom.
It is designed to be loosely fitted and guided within a lower rail 11 laid along the sill material. Therefore, if the pull joint stile 8 is pulled in the direction of the doorstop frame 13, the shutter will be in the closed state,
Conversely, if you pull the handle stile 8 in the direction of the hanging frame 5, the shutter pieces 1, 1... will move toward the right end of the hanging frame and will be pulled into the folding shelter position at each joint joint 3, 4, 4'. After folding into a folded shape, the shutter is opened.

In the present invention, in particular, at least one of the joint joints 4, 4, . As shown in Figure 4, the biggest feature is that it is made with a split mold.

To explain this point, the joint 4 in this embodiment has a round pipe-shaped C-shaped hinge shaft 42 formed in the longitudinal direction on one side, and a holding channel 43 extending the entire length on the other side. a female joint piece 41 formed over the above, and a splicing plate 4 that is fitted into the holding channel 43.
The hinge shaft 4 of the female joint piece 41 is attached to the side surface of the female joint piece 4a.
2 and a male joint piece 44 on which a hinge shaft 45 of the same shape is formed in a symmetrical relationship. In this embodiment, the female and male joint pieces 41 and 44 are connected to the cap nut 4.
6 and a fastening means such as a screw 47 so as to be integrally connected.

Therefore, in this embodiment, the side edge concave engaging portion 1a of the right shutter piece 1 is fitted in advance to the C-shaped hinge shaft 42 of the female joint piece 41, while the left shutter piece 1 ’ side edge concave engaging portion 1a
is fitted with the C-shaped hinge shaft 45 of the male joint piece 44 in advance, and after hanging the split shutter onto the hanger rail 10 attached along the lintel material, the female joint piece 41 If the male joint piece 44 is connected and integrated, the separately suspended shutter pieces will be connected to each other to form a series of foldable horizontal pulling shutters. However, in this embodiment, the joint joint 4', which is located second from the hanging joint frame 6, is located at the even numbered joint, and moreover, the joint joint 4' which is located second from the hanging joint stile 6 is located at the even-numbered joint, and moreover, the joint joint 4' is located at the even numbered joint, and moreover, the joint joint 4' is located at the even numbered joint joint 4', and the joint joint 4' is located at the even numbered joint joint 4', and the joint joint 4' is located at the even-numbered joint joint 4', and the joint joint 4' is located at the even numbered joint joint 4'. Although this is a departure from regulations, the vertically nested format is not adopted. This is because in this part, the number of shutter pieces 1 is still small, and even if they are not divided into molds, it will not cause any slight hindrance to the erection work.

Furthermore, in the illustrated embodiment, as shown in FIG. 2, a vertical frame material 80 is provided with a hook-like rib 81 on the hanging base side, and a C-shaped frame material 80 is provided on the hanging base side, which can be fitted into the rib 81. Split joint piece 82 with type hinge shaft 83
Since the "handle stile joint" 8, which is constructed by combining the two joints in a telescopic manner, has been adopted, a shutter is attached to the C-shaped hinge shaft 83 of the split joint piece 82 in advance before erection. After fitting the side edge concave engaging portion 1a of the piece 1 and hanging it, the vertical frame material 80 of the pull joint stile 8 and the split joint piece 82 are screwed together with the screw 84.
The connection can be made only by fixing it by the handlebar, and thereby it becomes possible to replace the pull stile joint 8 if it is damaged.

The horizontal shutter of this embodiment is generally constructed as described above, but the present invention is by no means limited to the above-mentioned embodiment, and various design changes may be made within the scope of the claims for utility model registration. is possible, and it is not necessary to configure all the even-numbered joints 4 into the vertically split telescoping type as described above. The joint 4 may be of a vertically split telescoping type only in the portion where the joint 4 is connected. Further, as shown in FIG. 5, it is also possible to adopt a joint member having locking rods 48, 48 as the even-numbered joints 4 to prevent tilting when subjected to wind pressure. In addition,
In FIG. 5, reference numeral 49 indicates a reinforcing rib, but other functional parts that are the same as those in FIG. 4 are given the same numbers and their explanations will be omitted.

[Effects of this invention]
