DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a louver in which louvers set on a frame are divided into several groups, and the fins divided into groups can be arbitrarily adjusted in angle.

[0002]

2. Description of the Related Art A general louver is used to adjust the inclination angle of a fin at a time to adjust light shielding and ventilation.

In other words, the structure is such that a number of fins are set on a frame, the respective action shafts of the fins are connected by a connecting rod built in the frame, and one fin is operated to collectively connect other fins. It is designed to adjust.

[0004]

In the above-mentioned conventional louvers, since the entire fin is adjusted to the same angle, it is impossible to partially adjust the line of sight. It has to be sacrificed.

In view of the above problems, an object of the present invention is to provide a louver in which a large number of fins set on a frame are divided into several groups, and the fin angle can be adjusted for each croup with a simple mechanism and operation. I do.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a large number of fins are swingably fitted to a frame,
In a louver in which the action shafts of the fins are connected by a connecting rod built in the frame so that the inclination angle of each fin can be adjusted collectively, the fins fitted on the frame are divided into two or more groups. A louver characterized in that a fin representative of the above is provided with the following angle adjusting means.

A base on which a hollow short axis is erected, and projections arranged at appropriate intervals with arc-shaped long holes on a concentric circle centered on the hollow short axis;
The projection on the base has a projection that can be engaged and released, and a hole penetrated by a pin implanted in the working shaft hole of the fin penetrating the arc-shaped long hole is provided, and is rotatably fitted to the hollow short axis. The lever shaft hole, and a hole in which the pin implanted in the working shaft hole of the fin fits into a long hole,
A spring is interposed in a gap between the hollow short axis and a long hole in which the hollow short axis fits. Both projections mesh with each other by the bias of the spring, and the mesh can be released by pulling up against the bias of the spring. A plunger acting by a push / pull spring is formed inside the lever, and a projection that fits with the projections arranged on the concentric circle is provided on a surface of the plunger facing the base at the pointed end of the plunger. The projections are engaged with each other by the bias of the push / pull spring, and the engagement is released by moving the plunger against the bias of the push / pull spring. .

According to the present invention having the above-described structure, the inclination angle of the fin can be arbitrarily adjusted for each group by a simple mechanism and its operation, so that the line of sight can be blocked without sacrificing lighting and ventilation. Will be able to do it.

FIG. 3 (a) is a front view of the fin angle adjusting means with a cover partially cut away, FIG. 3 (b) is a transverse sectional view, and FIG. 4 (a).
Is an assembled perspective view of the angle adjusting means, and (b) is a perspective view of the back surface of the lever. The fin angle adjusting means will be described with reference to these drawings.

The angle adjusting means 10 comprises a lever 12 and a lid 15 which are urged by a base 13 and a spring 14 to fit into a hollow short axis 16a of the base 13, and the base 13 has a hollow short axis 16a at its center. The projection 23 is provided on the concentric circle centered on the hollow short axis 16a, and the projections 23 are arranged at regular intervals with the arc-shaped long hole 8b. A short shaft 16b is provided upright.

The lever 12 has a hollow short shaft 16
A long hole 17 and an operating pin 9 which are fitted by being urged by the spring 14 penetrate through a, and a long hole 18 and a handle 19 having a length corresponding to the urging range of the spring 14 are provided.

The cover 15 has a hole 5b through which the fulcrum pin 6 penetrates the hollow short shaft 16b of the base 13, an arc-shaped long hole 8c similar to the arc-shaped long hole 8b, and a hole 20b through which the mounting screw 11 penetrates. Are provided.

Next, the assembly will be described. Base 13

Next, the pin hole 5a of the frame 2 and the hole of the hollow short shaft 16a of the base 13 are aligned with the fulcrum shaft hole 4 of the fin 1, and the fulcrum pin 6 is fitted from the frame 2 side. The operating pin 9 is connected to the connecting rod 3 while aligning the hole 21 of the rod 3, the arc-shaped long hole 8 c of the lid 15, the long hole 18 of the lever 12, the arc-shaped long hole 8 b of the base 13, and the working shaft hole 7 of the fin 1. The angle adjusting means 10 is attached to the position of the frame 2 corresponding to the fin 1a which is inserted from the side and represents the group.

When the attachment of the angle adjusting means 10 is completed, the working shaft hole 7 of the other fin 1 of the group and the hole 21 of the connecting rod 3 are aligned with each other, and the working pin 9 is moved to each fin 1.
3 and finally the frame 2 shown in FIG.
And the assembly is completed.

As shown in FIG. 5, a lever 12x is provided with a plunger 25 which is urged by a spring 14x to provide a mechanism for engaging and releasing the projection 23 of the base 13 and the lever projection 24 of the angle adjusting means 10, as shown in FIG. (A) The lever 12y is provided with a lever-side projection 24x on the surface facing the projection 23x. The lever 12y is provided with a plunger 25 which is biased by a spring 14y. The arrangement (b) provided with the projection 24y can be used. In addition, in the case of this method, by providing a long hole at a portion of the plunger through which the working pin passes, the positional relationship between the arc-shaped long hole and the concentrically arranged projections can be switched between inside and outside.

Next, the operation will be described with reference to FIG. When adjusting the inclination angle of the fin 1, the lever 12
When the handle 19 is turned while being pulled against the bias of the spring 14, the action pin 9 penetrating the lever 12 moves,
At the same time, the fin 1 and the connecting rod 3 move to adjust the inclination angle of the fin 1 of the whole group. When the handle 19 is released, the lever 12 returns to the original position by the bias of the spring 14 and the projection 24 on the back side of the lever 12 And the projections 23 concentrically arranged on the base mesh with each other to fix the inclined position of the fin 1,
As shown in FIG. 6, it is possible to adjust the tilt angle to an arbitrary value for each group.
