Description

[Detailed Description of the Invention] This invention relates to a movable louver that can be installed in a window of a building to adjust lighting and ventilation.

BACKGROUND ART Conventionally, the structures of the blades constituting a louver (shutter) and the brackets that transmit rotational force to the blades have been as shown in FIGS. 1 and 2 a and b, for example.

That is, this wing plate 1 has a main frame composed of a core shaft 2 and a plurality of horizontal bars 3 that are provided substantially perpendicularly to the core shaft 2 and symmetrically. A reinforcing member 4 in the shape of a groove connecting these tips is attached, and with panels 5 applied to both sides of the core shaft 2 and each horizontal beam 3, the ends of the reinforcing member 4 and both panels 5 are covered. It has a structure in which an elongated cap 6 is attached and blind plates 7 are attached to the upper and lower surfaces.

The blade 1 configured as described above rotates around the core shaft 2, and in order to perform this rotation,
For example, as shown in FIG. 2a, a bracket 8 is brought into contact with one end of the blade 1 and fixed with screws 10 on both sides of the rotating shaft insertion hole 9, and an interlocking rod ( (not shown), or as shown in Figure 2b,
An L-shaped bracket 1 is attached to the end of the panel 5 of the slat 1.
1 is screwed, and an interlocking rod is similarly pivotally attached to the other end of the bracket 11.

However, in the structure of the conventional movable louver in which the blade 1 and the brackets 8, 11 are connected as described above, one side of the brackets 8, 11 is simply screwed to the side surface of the blade 1. Because of the structure, each screw loosened as the blade 1 was rotated repeatedly through the brackets 8 and 11, causing rattling and misalignment between the blade 1 and the brackets 8 and 11. There were problems that could occur.

This idea was developed by focusing on the conventional problems, and even when the blade is repeatedly rotated through the bracket, it does not cause rattling or misalignment between the blade and the bracket. Furthermore, it is an object of the present invention to provide a movable louver that does not rotate idly.

This invention provides a movable louver in which a bracket for transmitting rotational force is attached to a rotatably held blade, in which a blade locking part is provided on the blade attachment part side of the bracket and protrudes into the blade. A bracket locking portion that engages with the blade locking portion is provided on the bracket attachment portion side of the blade, and the blade and the bracket are coupled with both the locking portions engaged. It is said that
