Also in this case, the center of gravity G moves in the range from the point a to the point b from the fully closed state shown by the solid line to the fully opened state shown by the chain double-dashed line, but the position of the emphasis point is on the rotation axis 42 over the entire locus. It is outside the axis.

[0004]

As described above, in the case of the conventional movable louver, since the position of the emphasis point is outside the axis of the rotary shaft 42 over the entire locus, the panel 40 (in the case of a single layer panel) or the A force equal to the weight of the panels 10 and 11 (in the case of a multi-layer panel) is necessary as the operation force when opening the louver. In particular, in the case of a multi-layer panel type movable louver, the total weight of the panel is twice as much as in the case of the single-layer panel, and the position of the center of gravity is further outside the room as compared with the case of the single-layer panel type movable louver. Therefore, when the arm 41a of the holder 41 has the rotation shaft 42,
Greater operating force is required to open the louver.

In view of the above problems, the present invention makes it possible to use the weight of a panel as an opening / closing force in a multi-layer panel type movable louver having a large panel weight, so that the opening / closing state is facilitated and the opened / closed state is It is an object of the present invention to provide one that is stably maintained and that can also ensure airtightness in a fully closed state.

[0006]

In order to achieve the above-mentioned object, the present invention provides a movable louver of a multi-layer panel type with respect to the axis of the rotary shaft of the multi-layer panel of each stage of the movable louver.
The center of gravity position of the corresponding multi-layered panel is on the outdoor side in the fully closed state, right above the axis of the rotating shaft in the predetermined half-opened state, and on the indoor side in the fully open state, It is characterized in that the positional relationship between the axis of each rotary shaft and the panel is set.

[0007]

The movable louver of the present invention is constructed so that the center of gravity of the panel passes over the axis of the rotating shaft within the locus range of opening and closing the louver. Therefore, when the panel is operated from the fully closed state to the fully open state, Rotates the panel against the gravity of the panel, and when the center of gravity exceeds the axis of the rotating shaft, the weight of the panel acts in the direction of opening. Conversely, when changing from the fully open state to the fully closed state, the center of gravity is When exceeds the axis of the rotating shaft, the weight of the panel acts in the closing direction, so that the opening and closing becomes easy. Further, in the fully closed and fully opened states, the weight of the panel acts in the closing direction and the opening direction, respectively, and the open / closed state is stabilized. Further, the weight of the panel can be used as a pressure contact force of the airtight material to another panel in the fully closed state, and the airtightness can be secured.
