[0006]

FIG. 1 is an overall view of a blind apparatus incorporating double-glazed glass according to the present invention, and FIG. 2 is a partial sectional view of a lower portion of FIG.
The double glazing 10 is constructed by fitting an outdoor glass 14 and an indoor glass 16 into a sash (frame) 12 having a rectangular cross section. Double glazing 10
Is fitted in a window frame 11 and a blind device 18 is arranged inside the window frame 11. Blind device 18
Are arranged in front and rear two rows in a space between the outdoor side glass 14 and the indoor side glass 16 so as to be rotatable in upper and lower frames of the sash 12,
The upper and lower ends of each of the upper and lower rotating shafts 26 are moved so that the front and rear two rows are relatively moved in the vertical direction by the rotation of 6.
Cords 24 and 25 that are connected to each other so as to be wound and unwound, a number of slats 20 that are supported at predetermined intervals in the vertical direction by the cords 24 and 25, and a sash so that a part of the 12 is provided in a frame below, and the teeth formed on the outer periphery of the
And an operation dial (operating device) 28 which is engaged with teeth formed on the outer periphery of the shaft and rotates the rotation shaft 26 when the teeth are rotated.

As shown in FIG. 3, the cords 24 and 25 have a structure in which openings 30 and non-openings 32 are formed alternately and continuously (only one cord 24 is shown in FIG. 3). It is shown.). The opening 30 has a slat 20 inserted therein to support the slat,
The slats 20 cannot be inserted into the non-opening portions 32. The length of the opening 30 is set larger than the length of the non-opening 32. As a result, as shown in FIG. 2, the cords 24 arranged on the front side (the left side in the figure)
When the slats 20a supported by the slats 20a and the slats 20b supported by the cord 25 arranged on the rear side (right side in the figure) are alternately arranged in the vertical direction, the slats 20b
The upper and lower ends are configured to overlap the slats 20a. This prevents light leakage from between the upper and lower slats 20a and 20b.

Next, the operation of the present invention will be described. As shown in FIGS. 1 and 2, when the upper and lower ends of the slats 20 b overlap the slats 20 a and are arranged alternately in the vertical direction, light is blocked by all the slats 20, so that the blind device 18 is not used. Is in a light-shielded state. To change from this state to the non-light-shielded state, first, the operation dial 28 is rotated in a predetermined direction. Thereby, the rotating shaft 26 rotates clockwise in FIG. For this reason, the front cord 24 is unwound from the lower rotating shaft 26 and is wound on the upper rotating shaft, so that it rises, while the rear cord 25 is wound on the lower rotating shaft 26. As it is unwound from the upper rotating shaft, it descends. As a result, the front slat 20a is raised and the rear slat 20b is lowered, so that the slats 20a and the slats 20b coincide with each other in height as shown in FIGS. This allows light to pass between the vertically adjacent slats 20, so that the blind device 18 is in a non-light-shielded state. next,
In order to bring the blind device 18 into the light shielding state, the operation dial 28 is rotated in the opposite direction to the above, and the rotation shaft 26 is rotated counterclockwise in FIG. This gives Code 2
As the cord 4 rises and the cord 25 rises, by moving the slats 20a and the slats 20b to the state shown in FIGS. In the first embodiment, the two cords are arranged in the front and rear two rows, and the upper and lower ends are respectively connected to the upper and lower rotating shafts. However, the present invention is not limited to this. Then, the upper and lower ends of the loop may be wound around the upper and lower rotating shafts, respectively.

FIGS. 6 and 7 show a second embodiment. This is because the cord 40 arranged on the front side is connected to upper and lower fixed shafts 44 (the upper fixed shaft is not shown) fixed in the upper and lower frames of the sash 42 and arranged on the rear side. Only the cord 41 is connected to the upper and lower rotary shafts 46 while being kept in tension by an upper rotary shaft (not shown) constantly biased in a winding direction by a spring (not shown) or the like. Except for this, the structure is the same as that of the first embodiment. Thus, the front cord 40 is fixed so as not to be movable, and the rear cord 41 is movable in the vertical direction.

Next, the operation of the second embodiment will be described. As shown in FIG. 6 and FIG.
Slats 48a supported by the front cord 40 at the upper and lower ends of the slats 48b supported by the slats 48a
When the light is blocked alternately in the vertical direction, the light is blocked by all the slats 48, so that the blind device 50 is in a light blocking state. To change from this state to the non-light-shielded state, first, the operation dial 52 is rotated in a predetermined direction. Accordingly, the lower rotating shaft 46 rotates clockwise in FIG. 7 to wind up the rear cord 41, and the upper rotating shaft unwinds the rear cord 41. Therefore, the rear slat 48b descends, and as shown in FIGS. 8 and 9, the height positions of the front slat 48a and the rear slat 48b coincide with each other and overlap. Accordingly, light can pass between the vertically adjacent slats 48, and the blind device 50 is in a non-light-shielded state. Next, in order to bring the blind device 50 into the light shielding state, the operation dial 52 is rotated in the opposite direction to the above, and the rotation shaft 46 is rotated counterclockwise in FIG. As a result, the rear cord 41 is connected to the upper and lower rotating shafts 4.
Since the tensioned state is always maintained between the portions 6, the rear slats 48b rise because the unwinding from the lower rotating shaft 46 causes the winding to be wound on the upper rotating shaft. When the rear slat 48b is moved until it and the front slat 48a reach the state shown in FIGS. 6 and 7,
The blind device 50 enters a light-shielding state.

In the first and second embodiments, the cord is moved by operating the operation dial and rotating the rotating shaft. However, the present invention is not limited to this. For example, a slat or cord may be used. Alternatively, the cord may be moved by attaching a magnetic metal piece to the base and adsorbing the magnetic metal piece from the outer surface with a magnet.

[0012]

According to the present invention, the cords respectively supporting the slats are arranged in two rows in front and rear in the space between the glasses, and both ends of at least one of the cords can be wound and unwound on a rotating shaft. By connecting and rotating the rotating shaft,
By moving the cords in the front and rear two rows in the vertical direction and moving the slats in the front and rear relative to each other, the blind device can be switched between a light-shielded state and a non-light-shielded state. Therefore, the number of parts is small and the shape is simple, so that the number of processing steps can be reduced, the assembling performance can be improved, and the quality can be kept constant.
