Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a blind louver as a fence used on the side of a highway or elsewhere.

[Conventional technology]

Although there are various methods for assembling such a louver, it is suitable for each member to be made of extruded aluminum alloy, which is durable and resistant to rust. When assembling such metal members, it is customary to connect each member to each other by bolts or screws rather than by welding in order to save time and effort on site.

Figures 4 to 6 show an example of such a louver, in which 1 is a hollow column as a support member that is erected from the concrete floor or the ground surface, and 2 is a hollow column.
indicates the louver installed between these pillars 1.

The louver 2 has a large number of shielding plates 4 on the left and right frame members 3.
In the illustrated example, a bis pocket 4a is integrally formed on the shielding plate 4, and this bis pocket 4a is used to secure the shield plate 3 to the frame material 3 with tapping screws. are doing.

Further, the louver 2 is attached to the side of the support 1 with bolts or screws via mounting pieces 5, 5' projecting from the frame 3 and the support 1, or a single bracket. 6 in the figure is the pillar 1,
This is a Kasagi that spans the top of the first room.

Note that the louver 2 may be attached to the frame material 3 using a wall of another structure as a supporting member, without using a column as a supporting member.

[Problem that the invention attempts to solve]

However, with conventional louvers like this, the ends of the members are only screwed or bolted together with their ends abutted, so they are susceptible to strong external shocks such as those caused by car collisions or falling luggage from trucks. In such a case, there is a risk that the pillars, frame materials, and frame materials and each shielding plate may come apart and scatter.

Further, the portion where the mounting piece is located is wide, and the distance between the support and the frame of the louver increases, resulting in an unsightly appearance.

The purpose of the present invention is to eliminate the disadvantages of the conventional example,
While securing the ease of assembly with screws, the connection between the parts is strong, and even if the parts are destroyed by a strong impact from the outside, the parts will not fly off, and the connection between the parts in the assembled state is tight. To provide a blindfold louver that improves appearance.

[Means for solving problems]

In order to achieve the above object, the present invention bulges the center part of the frame material inward to form a hollow protrusion so as to form a groove that opens outward. The gist is to form a louver by arranging shielding plates between the frame members so as to fit into the hollow protrusions, and to insert the protrusions provided on the support member into the grooves of the frame members. It is something to do.

[Effect]

According to the present invention, the frame material and the shielding plates arranged in a row between them are firmly connected in a fitted state to form a louver, and this louver has a ridge formed on a supporting member such as a column by a groove in the frame material. Since it is installed so that it goes deep inside, it will not fall apart all at once even if a strong force is applied from the outside.

Furthermore, since the frame material is fitted into the ridges of the support member and is reinforced by the ridges, it can be made thinner, and the distance between the support member and the louvers can be narrower than before.

〔Example〕

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

FIG. 1 is a cross-sectional plan view of essential parts showing one embodiment of the blind louver of the present invention, and FIG. 3 is a front view of the same.

In the figure, 1 is a hollow column, 2 is a louver formed by arranging shielding plates 4 on a frame member 3, and these members are constructed using extruded aluminum alloy members. Further, as shown in FIG. 4 of the conventional example, a bis pocket 4a is formed in the longitudinal direction of the back surface of the shielding plate 4.

In the present invention, the center portions of the left and right plate-shaped frame members 3 are largely bulged inward in the longitudinal direction to form hollow protrusions 7. The inside of this hollow protrusion 7 is configured as a groove 8 that opens outward.

On the other hand, U-shaped notches 9 are provided at both ends of the shielding plate 4, which are approximately the same shape as the hollow protrusion 7 and slightly larger.

In this way, the hollow protrusion 7 is inserted into the notch 9.
are inserted, and the louver 2 is assembled by arranging the shielding plates 4 diagonally between the frame members 3 and 3 in a fitted state.

These louvers 2 are further fixed with wires 11 disposed vertically so as to stitch the ends.

In addition, a bracket 10 having an L-shaped cross section is screwed in the longitudinal direction of the side of the central column 1 as a supporting member which is erected at intervals, and the protruding rim of the frame member 3 is attached to the ridge 10a protruding from the bracket 10. The louver is inserted between the columns so that the grooves 8 in the grooves 7 are connected, and the protrusion 10a and the hollow protrusion 7 are fixed with screws, so that the louver 2 is attached between the columns 1 and 1.

Note that screwing the protrusion 10a and the frame material 3 may be omitted; in this case, in order to prevent rattling, the protrusion 10a and the frame material 3 are pressed with bolts so that they are identified. In addition, on the other side, the protrusion 10a and the frame material 3 are in a fitted state with a small gap,
It is also possible to apply a seal.

Figure 2a shows a second embodiment of the present invention,
The protrusion may be integrally molded with the support 1, and may be formed as a protrusion 1a that projects directly from the side of the support 1.

Note that when the louver 2 is directly attached to a wall other than the support 1, the bracket 10 described above will be used, but in either case of FIG. 1 or FIG. They may be provided discontinuously.

Furthermore, by being inserted into the groove 8, the protrusions 10a, 1a also serve as reinforcing pieces that reinforce the hollow protrusion 7 from the inside, and in order to make this role more effective, has a protrusion 10a,
As shown in FIG. 2b, it is preferable that 1a has a thick wall so that it can be fitted into the groove 8 as closely as possible.

[Effect of idea]

As mentioned above, the blindfold louver of this invention is
The frame material and shielding plate that make up the louver are connected in a fitted state other than by screws, and the louver and support members such as columns are connected so that the protrusion on the support member side is inserted into the groove on the louver side. With this installed, the connections between the parts will be strong, and even if a strong impact is applied, such as in a car collision or falling cargo from a truck, the parts will not fall apart or break apart.

Moreover, when the louver is attached to the support member, the louver frame material and the support member are fitted, so the gap is reduced and the appearance is improved.
