Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a blind device that is arranged on a window or the like of a building and blinds these windows or the like as necessary.
[0002]
[Problems to be solved by the invention]
In this type of blind device, a blind composed of a plurality of slats juxtaposed in the vertical direction is usually arranged at the top, and the blind is lowered from above by the operation of the lifting device, thereby concealing the openings such as the windows of the building. The blind is raised by the reverse operation of the lifting device to open the opening.
[0003]
In such a blind device, as described above, when the opening portion is opened, a plurality of slats constituting the blind are usually arranged in close proximity to each other above the opening portion, so that even when fully open, The polymerized slats partially close the opening, and when the opening is fully opened, a sufficient feeling of release cannot be experienced, which is annoying. In order to eliminate this, even if the slat accommodation frame is provided above, the space occupied by the slat accommodation frame is required above, and this may be difficult in general houses and buildings, and is not always satisfactory. . In addition, in the case where it is desired to blindfold only below the opening, there is a problem that it cannot be done with the conventional blind device, and furthermore, cleaning of the slats must use a ladder, a stand, etc. There is also a risk that an object or a person may be caught by the lowering of the blind in the closing operation.
[0004]
Therefore, a blind device has been proposed in which a plurality of slats constituting the blind are lifted below the opening when the opening is opened and a slat is lifted via a link mechanism when the opening is closed. According to the proposed blind device, the above-mentioned various problems can be preferably solved, and this is satisfactory. However, when the blind device is juxtaposed to each of the windows of the building arranged side by side, As a result, it is required to narrow the space between the blind device and the blind device in relation to the column width. As a result, the vertical frame that accommodates the link mechanism or the like also needs to be narrowed. In the case of a narrow vertical frame, it is very difficult to attach the link mechanism, and to perform maintenance and inspection.
[0005]
The present invention has been made in view of the above-described points. The object of the present invention is to make the vertical frame narrow and to easily perform the attachment work, maintenance, and inspection of the link mechanism. An object of the present invention is to provide a blind device that can be preferably juxtaposed in each of a plurality of windows arranged in a horizontal direction in a building or the like.

[0010]
In the blind device according to the third aspect of the present invention, in the blind device according to the first or second aspect, the tilt mechanism tilts the slats at intervals from each other when the opening is closed, thereby opening the opening. Then, they are arranged substantially horizontally and overlap each other.
[0011]
According to the blind device of the third aspect, since the slats are inclined with a distance from each other in the closed state of the opening, the wind can escape through this distance, so that the open state is in the closed state. Thus, it is possible to prevent each slat from being excessively deformed by the wind pressure in a strong wind.
[0012]

[0030]
In the blind device 1 described above, when the opening 16 is closed, the electric motor 47 is operated by operating an operation switch (not shown), the sprocket wheel 44 is rotated via the speed reducer 46 and the rotary shaft 45, and the chain 41 is run. When the movable piece 42 is lifted by the traveling of the chain 41, the uppermost slat 4 is lifted as shown in FIGS. 7 and 8, and the slat 4 following the uppermost slat 4 is also connected via the link mechanism 7. When the movable piece 42 is lifted in sequence and the movable piece 42 is further lifted, the contact of the cam roller 54 with the inner surface 55 of the vertical frame 2 is released. As shown in FIG. 5, the uppermost slat 4 is shown in FIG. 2 via the rotatable shaft 52 and the swingable plate 51 by the rotation of the rotatable arm 53 in this direction. Thus, the uppermost slat 4 is rotated in such a direction, and the link row 26 is lifted more than the link row 25 by the rotation of the uppermost slat 4, and the lowermost portion following the uppermost slat 4. As shown in FIGS. 2 to 4, each slat 4 of FIG. There is inclined at a distance to be brought into the opening closed. When the blind 5 made of the slat 4 closes the opening 16, the operation of the electric motor 47 is stopped by a detection signal from a detector (not shown).

When the opening 16 is opened from the closed state of the opening 16 by the blind 5 shown in FIGS. 2 to 4, the electric motor 47 is operated reversely by the operation of an operation switch (not shown) to rotate the speed reducer 46 and the rotation. The sprocket wheel 44 is rotated via the shaft 45, thereby causing the chain 41 to travel in the opposite direction. When the movable piece 42 is lowered by the reverse travel of the chain 41, the uppermost slat 4 is lowered and the contact of the cam roller 54 with the outer surface 57 is released, and then the cam roller 54 contacts the inner surface 55. Then, the pivotable arm 53 is pivoted in the opposite direction to that described above, and the pivotable arm 53 pivots in this direction through the pivotable shaft 52 and the swingable plate 51. The upper slat 4 is rotated in the opposite direction to the above and arranged substantially horizontally, and the link row 26 is linked by the rotation of the uppermost slat 4 in this direction and the horizontal arrangement. The lifted state more than the row 25 is eliminated, and each slat 4 following the uppermost slat 4 is lowered substantially horizontally and parallel to each other, and further lowering of the uppermost slat 4 7 and 8, as shown in FIGS. 26 with successively folded from the bottom of, sequentially superimposed one another from the lowest slat 4, finally slat 4 the uppermost superimposed slats 4 of the immediately below, results in the opening open. When the blind 5 made of the slat 4 opens the opening 16, the reverse operation of the electric motor 47 is stopped by a detection signal from a detector (not shown).
[0032]
When the operation or reverse operation of the electric motor 47 is stopped by operating the operation switch or the like during the operation or reverse operation of the electric motor 47, the blind 5 brings the opening 16 into a halfway closed state or a halfway open state. When the operation and the reverse operation of the electric motor 47 are performed again by the operation of the operation switch or the like in the halfway closed state or the halfway open state of the opening 16 by the blind 5, the same operation as described above is performed from that state.
[0033]
By the way, in the blind device 1, each of the link rows 25 and 26 is rotatably connected to each end portion 6 of the slat 4, and the link mechanism 7 is arranged outside the vertical frame 2. The frame 2 can be narrowed, and the link mechanism 7 can be easily attached, maintained, and inspected. Thus, the blind device 1 can be installed in each of a plurality of windows arranged side by side in a building or the like. It can be preferably juxtaposed.
[0034]
Further, according to the blind device 1, since each of the link rows 25 and 26 is rotatably connected to the respective end portions 6 of the slats 4 in the recesses 19, the link mechanism 7 is arranged outside the vertical frame 2. Even if it is made, the clearance gap between the slat 4 and the vertical frame 2 can be made as small as possible, and the opening part closing function by the blind 5 can be obtained more completely.
[0035]
In addition, according to the blind device 1, the slats 4 are inclined with an interval in the closed state of the opening, so that the wind can be escaped through this interval. Thus, it is possible to prevent the slats 4 from being excessively deformed by the wind pressure during a strong wind.
[0036]
Furthermore, according to the blind device 1, since the end 6 of each slat 4 can be held at the position of the slit 10 of the vertical frame 2 by the slat position holding means 11, the blind 5 can be prevented from shaking due to wind or the like.
