Description

[Detailed explanation of the idea] The present invention relates to louver blades.

Like louvers, louvers are mainly installed at the openings of the outskirts to protect the inside of the outskirts from sunlight, wind and rain, or to act as a rectifying path for ventilation. It is desired that the installation angle and extension be easy depending on the degree of use, and that it be lightweight and strong.

The present invention was developed from this perspective,
As illustrated in FIG. 1, its basic structure is a hollow long hexahedron.

The upper surface 2 and the lower surface 3 are parallel surfaces, the left side 4 and the right side 5 are end surfaces cut along a plane perpendicular to the parallel plane, and the front surface 6 and the rear surface 7 are not necessarily the upper and lower surfaces. No need for orthogonality.

Therefore, the cross-sectional shape of the elongated material is generally a hollow square, rectangle, parallelogram, trapezoid, or the like, even if there are bolt holding grooves to be described later.

The distance between the upper 2 and lower 3 planes refers to the thickness of the blade 1, and the reason why these two sides are parallel is that it is convenient to extend blades of the same thickness to the front. The distance between the 4 and right 5 sides refers to the width of the blade 1, and the reason why it is a cut end surface with a plane perpendicular to the upper and lower surfaces is to facilitate expansion of the louver width in the left-right direction, that is, the width of the louver.

On the other hand, the reason why the angles with respect to the upper and lower surfaces of the front surface 6 and the rear surface 7 are not specified is that it is generally desired that the louver be installed at a certain angle of inclination with respect to sunlight, so it is not necessarily a right angle. Although it is not an advantage.

Incidentally, the rear surface 7 of the blade of the present invention is provided with one or more mounting bolt holding grooves 8, 8', which are of course used when fixing the louver blade to the support.

Since this bolt holding groove is a groove, it is preferably a circuit extending in the length direction of the louver blade, and has a narrowed entrance to prevent the bolt head from falling out as shown in the figure.

In this case, since the louver blade can slide in the width direction while holding the bolt head in the groove, it has the advantage that the mounting position can be easily adjusted.

The reason why the blade 1 of the present invention is hollow is that it can be made lightweight without significantly reducing the strength using as little material as possible. It can be easily and inexpensively manufactured using extrusion molding from aluminum or synthetic resin.

A connecting pin insertion groove 9 is provided at the front corner end of this hollow portion to be used when connecting the blades 1 in the left-right direction. You can zoom in or out.

In addition, the upper and lower surfaces of the blade of the present invention are provided with extended blade fitting strips 1a and 1b as extensions in the front direction, so that the blade can be fitted onto the front surface of the blade, or the fitted blade can be can be easily removed.

The shape of the fitting strip will be described later when explaining the extended blade in FIG. 3, which is outside the scope of the present invention.

FIG. 2 shows the left end face of an embodiment of the blade of the present invention as described above, which has a shape different from that shown in FIG. 1.

Since the end face of the one shown in FIG. 2 is a parallelogram with θ=45° as a whole, a louver with a blade angle of 45° can be obtained by directly attaching this to a vertical support.

FIGS. 3 and 4 are left side views of the extending blades used when it is desired to extend the louver according to the present invention in the front-back direction,
The blade 10 in FIG. 3 is an intermediate extending blade, and the blade 11 in FIG. 4 is a front end extending blade.

Their basic shape is preferably such that they have an angle θ and a thickness H in FIG. 2, and are arranged on an extension of the upper surface 2 and the lower surface 3.

Fitting strips 10a and 10b are provided on the front surface of the intermediate extending blade 10.
Engagement strips 10C and 10d are provided on the rear surface, and engagement strips 11C and 11d are provided on the rear surface of the front end extending blade.

As shown in the figure, the tip of the fitting strip a is a downward hook-shaped body, the tip of the corresponding engagement strip C is a hook-shaped body pointing upward, and the tip of the fitting strip is a male-shaped arc, and the corresponding engagement strip C has a hook-shaped tip pointing upward. The ends of the joints d are female-shaped.

Therefore, by connecting the male and female parts of the mark and d, it can be rotated as a hinge, and by rotating the extending blade around this part, the connection of the hook-shaped body between the fitting line a and the engaging line C is completed. This means that the extension blades 10 and 11 can be extended with respect to the blade 1 according to FIG. 2 of the present invention.

In this way, how to extend the extension blades to the blade 1' in FIG. 2 is indicated by symbols: 1'+11, 1'+10+11
．． 1'+n, 10+11.

Of course, the blades in Figures 1 and 2 are not extended;
It can be used alone.

The typical size of one of these blades mentioned above is H75m.
m, width is approximately 88 mm.

Since it is extruded, it can be made to a length of several meters or more, but for convenience of handling, it is cut to a length of about 300 crn.

The state in which the invented blade is attached to the support as a louver is the fifth one.
It is shown in FIG.

That is, the bolt 1 is inserted into the mounting bolt holding groove 8, 8' in the blade.
It is sufficient to hold the head of No. 3 and tighten it with a nut from the column 12 side.

When the width and depth of the blades are insufficient, the case where the blades are connected in the width and depth directions is shown in FIG. 7 for better understanding.

That is, two blades 1'. 1' are lined up in the width direction and bolted to the pillars 12, respectively, and the front end extending blades 11 are fitted and engaged to extend on the outside of the blades 1' in order to extend in the depth direction. , at both ends of these blades, the coupling pins 14 are inserted into the insertion grooves 9. of the adjacent blades.
It is inserted across 9.

In addition, the figure shows the case where the blade is installed at an angle of 45° to the support column 12, but if you wish to change that angle, it is necessary to install a triangular cross-section between the rear surface of the blade (strictly speaking, the rear surface of the mounting groove). All you have to do is wedge it.

Of course, it is obvious that blades having angles of 15°, 30°, etc. in θ can be manufactured from the beginning.
