Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a slat structure for a panel shutter that is attached to an opening such as a doorway of a building.

[Problems to be solved by the prior art and the invention] In general, this type of panel shutter has the following problems:
There is a slat that is used as a panel shutter by interposing a panel plate such as a glass plate or a synthetic resin plate between upper and lower horizontal frames that extend in the left-right direction. However, in this case, for example,
As shown in Japanese Patent Application Laid-open No. 166154 and Japanese Patent Application Laid-Open No. 59-72385, opposing fitting grooves are formed in the upper and lower horizontal frames, respectively.
If both the upper and lower edges of the panel body are fitted into this fitting groove, especially if the opening is wide, long slats must be used, and the horizontal frame will inevitably bend due to wind or its own weight. The panel board may come off the horizontal frame due to bending, and to prevent this, a vertical frame is supported between the upper and lower horizontal frames and the space formed by the horizontal frame and vertical frame is It was necessary to configure the structure so that the panel board could be fitted into it. However, in this case, the panel board was formed by being inserted into each space, so it was difficult to prevent rattling and
In order to improve airtightness, it is necessary to insert sealing material around all four sides of the panel body, which not only increases the number of parts but also increases the total weight of the shutter curtain, making the winding device less sturdy. However, there was a problem in that the assembly work was extremely complicated and troublesome, and the workability was significantly reduced.

[Means for Solving the Problem] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a slat for a panel shutter that can eliminate these drawbacks. The slats constituting the tar curtain are composed of upper and lower horizontal frames each having a connection part that connects the upper and lower parts rotatably, and a panel plate interposed between the upper and lower horizontal frames, and is formed into a panel plate. It is characterized by a configuration in which the locking strips are fitted into and incorporated into engagement receiving strips formed on the upper and lower horizontal frames, respectively, so that they can only be moved in the left and right direction.

With this configuration, the present invention allows even if the slat is used for something with a wide width, it can be passed through one slat without assembling it using panel boards cut into short pitches in the longitudinal direction as in the past. It is possible to use long panel boards, which in turn eliminates the need for any vertical frames, greatly simplifying the structure, reducing the number of parts, and improving workability and quality.
Furthermore, it is possible to reduce costs.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes a panel shutter installed at the opening of a building, and the shutter curtain constituting the panel shutter 1 is wound up by a winding device 2 and rewound to the left and right guide rails 3. It is designed to open and close the frontage by being guided and moving up and down. A slat 4 constitutes the shutter curtain, and the slat 4 is composed of a panel plate 5 and upper and lower horizontal frames 6 and 7.
Here, the panel board 5 is extrusion molded from a transparent or translucent resin material such as polycarbonate, and the upper and lower edges of the panel body 5 have locking strips that protrude in a substantially cross shape. 5a, 5a are formed. On the other hand, the upper horizontal frame 6 and the lower horizontal frame 7
is made of a shape extruded from a metal such as aluminum or an appropriate synthetic resin, and the upper horizontal frame 6 has a concave groove-shaped connecting portion 6a, and the lower horizontal frame The frame 7 has a protruding connecting part 7
a, and the above-mentioned locking strips 5 of the panel body 5 are provided on the mutually opposing inner sides of the upper and lower horizontal frames 6 and 7.
Cross groove-shaped engagement receiving strips 6b, 7b are provided, respectively, into which the engagement receiving strips 6b, 7b are slidably fitted in the left and right directions, and the locking strips 5a, 5a are fitted on the engagement receiving strips 6b, 7b.
The slats 4 are formed by slidingly fitting them in the left and right directions, respectively.
Further, the upper and lower horizontal frames 6, 7 have bis pockets 6c, 7c in the center, and hollow parts 6e, 7 around them.
Further, inclined surfaces 6d and 7d are formed in the vicinity of the connecting portions 6a and 7a so that the slat 4 is wound up to a diameter as small as possible during winding.
In this embodiment, the cross-sectional outline of the horizontal frames 6 and 7 is rectangular, but it goes without saying that the shape is not necessarily limited. In order to prevent the panel board 5 from sliding sideways, a cover (not shown) is provided on both sides of each horizontal frame to cover and hide the hollow part.
Just screw it on.

FIG. 4 shows a slat 4 according to a second embodiment. In this case, the shape of the upper and lower edges of the panel board 5 is changed. That is, whereas in the first embodiment, protruding cross-shaped locking strips 5a are formed on the upper and lower sides, in the second embodiment, the locking strips 5a have double-headed H-shaped protrusions. . In addition, the upper horizontal frame 6 and the lower horizontal frame 7 are not made of extruded material.
The horizontal frames 6 and 7 are double roll-formed from strip-shaped thin steel plates, and the horizontal frames 6 and 7 are formed with engagement receiving strips 6b and 7b that widen toward the back so that the locking strip 5a can be slidably fitted therein. Reference numerals 6a and 7a designate connecting portions which are different in shape from those of the first embodiment and are interlocked to be rotatably connected to each other. 6d, 7
Similarly, d is an inclined surface.

In the embodiment of the present invention constructed as described above, the slats are connected to the upper and lower horizontal frames 6, as described above.
The shutter curtain is assembled using the slat 4, which is extremely easily assembled by sliding the locking strips 5a, 5a of the panel board 5 into the engagement receiving strips 6b, 7b formed in the slats 7 from the left and right directions, respectively. When the slats 4 are formed, the panel board 5 and the upper and lower horizontal frames 6 and 7 are configured in a relationship that allows them to move only in the left and right directions, so it is recommended that the slats 4 be built in an opening with a wide frontage. Even if it is attached, there is no inconvenience that the horizontal frames 6 and 7 are bent as in the conventional case, and therefore, the vertical frame is not required at all, and it is possible to have excellent airtightness. The structure can be greatly simplified, and this can also greatly contribute to cost reduction.

[Function and Effect] In summary, the present invention is constructed as described above, and the slats constituting the panel shutter are composed of upper and lower horizontal frames and a panel plate interposed between the horizontal frames. However, the horizontal frame and the panel board are integrally connected and assembled with a structure in which the locking strip and the engagement receiving strip are fitted so that they can only move in the left and right direction. Even when used in an opening with a wide width, the horizontal frame does not bend at all, so the vertical frame that was conventionally required can be eliminated and a single panel plate can be used, making the structure simple. Moreover, it can be made to have a smooth feel, has excellent airtightness, and can not only be lightweight but also significantly reduce costs.
