BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric louver provided on a skylight or the like and capable of shielding sunlight.

[0002]

2. Description of the Related Art As a conventional electric louver, for example, there is one disclosed in Japanese Utility Model Laid-Open No. 1-114782. In this electric louver, a moving rod is axially moved by a motor installed on a beam, and a large number of louver blades are connected to the moving rod to open and close the louver. Since a gap is formed between the louver blade and a mounting frame that supports the louver blade, a large number of shield plates are provided to shield the louver blade. The shield plate is structured to be sandwiched between the end members of the pair of louver blades.

[0003]

However, in the conventional electric louver as described above, since the motor is arranged on the beam, when the louver is opened, the motor can be seen through the louver. There is a problem. Further, since the shield plate is sandwiched between the end portions of the louver blade, there is a problem that the end portion of the louver blade has a complicated shape. The present invention aims to solve such problems.

[0004]

According to the present invention, a louver opening / closing motor is arranged inside a louver blade.
The above first problem is solved. That is, the electric louver according to the present invention includes a louver opening / closing motor (16) inside one or more of a plurality of aligned louver blades (14) linked by a link mechanism (36, 38, 40). Are arranged.

Further, the second problem is solved by making the shield plate one structure which is movable. That is, in the electric louver according to the present invention, a position for closing a gap between a plurality of aligned louver blades (14) in a fully closed state and a louver mounting frame (11) located at both ends in the longitudinal direction of the louver blade (14), A shield plate (18) is provided which is movable between the position where the clearance is opened and the shield plate can be driven by a side seal motor (46).

Since the louver opening / closing motor is housed in the louver blade, it is not necessary to install the motor or the like on the beam, and the appearance is improved when the louver is opened. Also, the clearance between the louver mounting frame and the louver blade is
Since it is closed by one shield plate which is almost equal to the length of the louver mounting frame, the end shape of the louver blade is simple and the shield plate mounting work is simplified.

EXAMPLE FIG. 3 shows the entire electric louver. A large number of louver blades 14 are arranged in a space between the beam 10 and the beam 12 in a direction orthogonal to the beam 10 in a state of being aligned at equal intervals. Each louver blade 14 is rotatably supported as will be described later, and is also linked so as to interlock with each other by a link mechanism described later. A louver opening / closing motor 16 schematically shown in FIG. 4 is arranged inside a predetermined one of the louver blades 14. Further, a shielding plate 18 is provided along the beam 10, and the shielding plate 1
8 is configured to be operated by a side sealing motor 46 described later. The louver opening / closing motor 16 and the side sealing motor 46 are operated by signals from the control panel 24 controlled by the switch 22.

FIG. 1 shows a portion of a louver blade 14 provided with a louver opening / closing motor 16. In FIG. 1, the left half shows a state in which the louver blade 14 is opened, and the right half shows a sectional view in a closed state. The louver opening / closing motor 16 includes the louver mounting frame 11 and the beam 10 via the mounting shaft 26, the support member 28, and the bracket 30.
It is stuck to. Rotating shaft 3 of louver opening / closing motor 16
2 is connected to the inside of the louver blade 14 so as to rotate integrally with a connecting member 34 that is fixed so as to be integral therewith. The louver blade 14 other than the louver blade 14 provided with the louver opening / closing motor 16 is provided.
Is rotatably supported by the louver mounting frame 11 at both ends thereof via bearings. A number of louver blades 14 have links 36 and 38 (FIG.
(See reference) and is connected to the common pipe 40. With this link mechanism, all the louver blades 14 rotate in conjunction with each other. A side seal device 44 is attached to the louver mounting frame 11 via a bracket 42. The side seal device 44 includes the side seal motor 4
6, a drive gear 48 driven by this, an intermediate gear 50 meshing with this, a rack 5 meshing with the intermediate gear 50
2, and the shield plate 18 that moves integrally with the rack gear 52
have. The shield plate 18 is a single plate extending between the adjacent beams 12 as shown in FIG.
The side seal motor 46 can move between a housed position and a projected position. At the protruding position of the shield plate 18, the tip end of the shield plate 18 contacts the side end portion of the louver blade 14 to shield it.

Next, the operation of this embodiment will be described. When the louver blade 14 in the opened state is closed, the switch 22 is operated to operate the louver opening / closing motor 16
To rotate. As a result, the louver blade 14 provided with the louver opening / closing motor 16 is rotated. Since each louver blade 14 is connected by a link mechanism including a link 36, a link 38, a pipe 40, etc., all the louver blades 14 are rotated by 90 ° from the state shown by the phantom line in FIG. Become. In this state, the ends of the louver blades 14 are overlapped with each other and are shielded. Next, side seal motor 4
6 operates to shield the side portion of the louver blade 14 by projecting the shield plate 18 in the storage position. This completes the shielding of the skylight. As described above, the operation of the control panel 24 when the electric louver is closed is shown in a flowchart of FIG. When the electric louver is opened, the reverse operation is performed. The operation of the control panel 24 in this case is shown in a flowchart of FIG.

The above-mentioned operation is performed by manual control, but it may be automatically controlled according to the brightness of external light. That is, a sunlight sensor for measuring outside light is provided, a signal from this is input to the control panel 24, and the angle of the louver blade is automatically controlled in response to this. As a result, control can be performed so that the louver blade angle is optimal according to the brightness of external light. It is also possible to use a timer to control the angle of the louver blade according to the time.

[0011]

As described above, according to the present invention, since the louver opening / closing motor is arranged inside the louver blade, the louver opening / closing motor and the like can be seen from below when the electric louver is opened. Is prevented. Since the side seal motor is small and is arranged in the louver mounting frame, it cannot be seen from below. Further, since the side end of the louver blade is shielded by the one shield plate that moves forward and backward, the shape of the side end of the louver blade can be simplified.
