(Prior art) In high-rise buildings, etc., double-glazed windows that are long vertically installed across each floor are usually equipped with glass plates that are fitted together or that can be partially rotated to open. Blinds are placed in between.

(Problems to be Solved by the Invention) In the above-mentioned conventional technology, when cleaning the inside of a windowpane that has been closed off, the blind suspended between the double panes of glass has become a major obstacle.

Structure of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a support frame in the form of a rectangular frame supported so as to be movable up and down between the double panes of glass along the window frame 2. A first blind 11 is disposed within the support frame 10, and a second blind 15 is suspended and supported from the lower stile 12 of the support frame 10, and the slat 14 of the second blind 15 can be raised and lowered by operating a lifting cord 37. That is.

(Function) With the above means, the second blind 15 can raise and lower its slats 14 by operating the lifting cord 37, and when the slats 14 of the second blind 15 are pulled up, the first blind 11
The support frame 10 supporting the can be lowered to a space where the second blind 15 is suspended and supported.

(Embodiment) An embodiment embodying the present invention will be described below with reference to the drawings.A glass window 1 installed from the floor to the ceiling of one or more floors of a high-rise building is shown in FIG. As shown in FIG. 4, glass plates 3a, 3b, 3c, and 3d are supported in parallel on the window frame 2, forming a double-glazed window.
The window frame 2 is constructed in the shape of a vertically long rectangular frame with two vertical frames 4, an upper frame 5, and a lower frame 6, and a pair of independent horizontal frames 7 in the front and rear are provided in the center of the frame. Each glass plate 3a, 3b and 3 constituting heavy glass
c and 3d are vertically divided into two by this horizontal frame 7. Glass plates 3a and 3b at the top of the horizontal frame 7
is supported in a fitted manner between the vertical frame 4, the upper frame 5 and the horizontal frame 7, and the lower glass plate of the horizontal frame 7 is rotatably supported on one side by a hinge 8, with only the glass plate 3c on the indoor side. It can be opened and closed.

Between the double-glazed windows, there is a first blind 11 in which both ends of the slats 9 are supported by a square frame-shaped support frame 10, and each slat 14 is connected to the lower stile 12 of the support frame 10 via a ladder cord 13. A second blind 15 that is suspended and supported is provided. The support frame 10 is constructed such that the guide piece 17 provided on the outer surface of the vertical stile 16 is guided by a guide groove (not shown) provided on the inner surface of the vertical frame 4 of the window frame 2, as shown in FIGS. 3 and 5. It is provided so that it can move up and down as shown in the figure. A stopper 18 that engages with an engagement hole (not shown) provided on the inner surface of the window frame 2 is provided at the lower part of the vertical stile 16 of the support frame 10. The support frame 10 is always held at the predetermined position shown in FIG. 3 by the stopper 18, and when the stopper 18 is released, it can be moved to the lower part of the window frame 2 as shown in FIG. It's summery.

In the first blind 11, as shown in FIG. 1, both ends of the slat 9 are fitted to a support shaft 19,
The support shaft 19 is rotatably and axially movably supported by the vertical stile 16 of the support frame 10. The support shaft 19 has a coil spring 2 disposed between the flange portion 20 at the tip thereof and the vertical stile 16.
The vertical stile 16 is urged outward by the urging force of 1. Therefore, an outward biasing force acts on the slat 9 at both ends thereof, thereby preventing the slat 9 from sagging under its own weight.

As shown in FIG. 2, the center of each rotating piece 22 is fitted into one support shaft 19 of each slat 9 so as not to be relatively rotatable, and both ends of each rotating piece 22 are connected to the vertical frame 1.
It is rotatably connected to two links 23 extending up and down along 6. The lower end of the link 23 is rotatably attached to a link gear 24 which is rotatably supported on the stile 16. When the link gear 24 is rotated, one link 23 is moved upward and at the same time the other link 23 is moved downward, so the rotating piece 22 is rotated and the support shaft 19 is rotated. It is becoming more and more like this.

Angle adjustment shafts 25 of the slats 9, 14 of the first and second blinds 11, 15 are rotatably and axially movably supported by the lower stile 12 of the support frame 10. And this angle adjustment shaft 25
A plurality of slats 14 are supported by the ladder cord 13, a bottom rail 26 is suspended from the bottom of the ladder cord 13, and the angle adjustment shaft 25 is rotated. Then, the angles of each slat 14 are adjusted in the same phase via the ladder cord 13. The angle adjustment shaft 25 is formed in the shape of a hexagonal rod, and is always biased by a coil spring (not shown) in one of the vertical frame 4 directions (in the direction of the arrow in FIG. 1) so as to protrude into the vertical frame 4. It's summery.
An operating knob 27 for moving the angle adjustment shaft 25 into and out of the vertical frame 4 has a base end fixed to the angle adjustment shaft 25 and a tip end protruding from a guide groove 28 provided in the lower stile 12 of the support frame 10. . and,
Due to the biasing force of the coil spring, the operating knob 27 is always positioned in the state shown in FIG. 1, with the angle adjustment shaft 25 protruding into the vertical frame 4. and move it to the guide groove 2 as shown by the chain line in the same figure.
8, the angle adjustment shaft 2
5 is designed to retreat from inside the vertical frame 4 and sink into the lower stile 12.

A drive gear 30 is fitted onto the angle adjustment shaft 25 at one end of the lower stile 12 so as to be non-rotatable. A transmission gear 31 rotatably supported by the vertical stile 16 meshes with the drive gear 30, and the link gear 24 meshes with the transmission gear 31. When the angle adjustment shaft 25 is rotated, the angle of the slat 14 of the second blind 15 is adjusted, and at the same time the angle of the slat 14 of the second blind 15 is adjusted. The angle of the slat 9 of the blind 11 is adjusted. At this time, the number of teeth and meshing of each gear 24, 31, 32 are set so that the angle of the slat 9, 14 of both blinds 11, 15 is adjusted in the same phase. has been done.

A rack gear 32 is rotatably supported at the position where the angle adjustment shaft 25 of the vertical frame 4 is projected, and when the angle adjustment shaft 25 is projected into the vertical frame 4, it becomes unrotatable relative to the rack gear 32. They are designed to fit together. The rack gear 32 is meshed with a rack 33 which is supported within the vertical frame 4 so as to be movable up and down. That is, the rack 33 is connected and fixed to the upper end of an operating shaft 34, the base end of an operating knob 35 is fixed to the operating shaft 34, and the operating knob 35 can be moved up and down within a guide groove 36 provided in the vertical frame 4. It is now possible to move. Therefore, the operating shaft 34 is controlled by the operating knob 35.
By moving the rack up and down, the rack 33 is moved up and down, and the rack gear 32 is rotated.

Each slat 14 of the second blind 15 includes:
An elevating cord 37 passes through the ladder cord 13 near the supporting portion, and one end of the elevating cord 37 is connected to the bottom rail 26. Lifting code 3
The other end of the support frame 10 is guided laterally within the lower stile 12 of the support frame 10, and then is suspended downward from the lower stile 12 via a stopper 38. Then, when the lifting cord 37 is pulled downward, the bottom rail 26 is pulled up, starting from the lower slat 14. Conversely, when the lifting cord 37 is pulled into the lower stile 12 by the weight of the bottom rail 26, the bottom rail 26 is pulled up. The rail 26 descends and the ladder cord 1 is removed from the upper slat 14.
It returns to the state supported by 3. The stopper 38 is activated immediately when the operator releases the lifting cord, and prevents the lifting cord 37 from moving due to the weight of the bottom rail 26.
can be held at a desired position, and when the operation is released, the bottom rail 26 can be moved up and down as desired by operating the lift cord 37.
Furthermore, when the bottom rail 26 is lowered to the lowest limit, the lifting cord 37 is almost pulled into the lower stile 12 except for the gripping part 39 at the tip, as shown in FIG. It is designed to be hidden behind the horizontal frame 7.

Next, the operation of the glass window 1 and the blinds 11, 15 configured as described above will be explained.

Now, as shown in Figure 3, the first blind 1
1 is supported at a predetermined position above the window frame 2, and with the bottom rail 26 of the second blind 15 lowered to its lowest limit, the operation knob 35 protruding from the window frame 2 is moved upward. Alternatively, when operated downward, the operating shaft 34 is moved and the rack gear 32 is rotated. When the rack gear 32 is rotated, the angle adjustment shaft 25 fitted to the rack gear 32 is rotated, and the angle of the slat 14 of the second blind 15 is adjusted via the ladder cord 13. At the same time, the rotation of the angle adjustment shaft 25 causes the drive gear 30 to rotate, and the link gear 24 to rotate via the transmission gear 31. Then, one of the links 23 is moved downward while the other is moved upward, so that the support shaft 19 is rotated and the angle of the slat 9 of the first blind 11 is adjusted. The angles of the slats 9 and 14 of the first blind 11 and the second blind 15 are adjusted in the same phase. As described above, the first blind 1 built into this double-glazed glass window 1
In the first and second blinds 15, the angle of the slats can only be adjusted by operating the operating knob 35 at all times.

When cleaning such a glass window 1, especially when cleaning the inner surfaces of the glass plates 3a and 3b that are supported in a fixed manner, first, the glass plate 3c rotatably supported by the hinge 8 is opened, and When the operating knob 27 protruding to one side of the lower stile 12 of the support frame 10 is operated in the direction opposite to the arrow in FIG. At the same time, it retreats within the vertical frame 4 and sinks into the vertical frame 16 of the support frame 10. Then, after pulling the lifting cord 37 of the second blind 15 downward to raise the bottom rail 26 to the maximum limit, when the stopper 18 of the support frame 10 is released, the support frame 10 moves downward along the vertical frame 4. It becomes movable.

From this state, as shown in FIG.
When the window frame 2 is moved to the lower part of the window frame 2, the first blind 11 does not exist between the glass plates 3a and 3b that are supported in a fixed manner above the horizontal frame 7, so the glass plates 3a and 3b The inner surface of the can be easily cleaned using a designated cleaning tool.
Moreover, the inner surfaces of the glass plates 3c and 3d below the horizontal frame 7 are attached to the second blind 15 without lowering the support frame 10.
If the slat 14 is in a raised state, it can be easily cleaned.

On the other hand, after cleaning the glass plates 3a, 3b, 3c, and 3d, the operation is the reverse of the above, that is, the support frame 10 is moved upward and held in a predetermined position by the stopper 18.
Operate the lift cord 37 to open the second blind 15
Lower the bottom rail 26 of the
After operating the angle adjustment shaft 25 to protrude into the vertical frame 4 and fit it into the rack gear 32, the glass plate 3c is closed. slat 11,
15 can be adjusted at the same time.

In the above embodiment, the support frame 10 is shaped like a rectangular frame, but it is shaped as shown in FIGS. 6 and 7 so as to avoid building beams, etc. at the upper center or upper side of the support frame 10. It is also possible to do so.

Effects of the Invention As detailed above, the present invention provides the second blind 1 suspended and supported from the lower stile 12 of the support frame 10.
5 and from that state to the space where the second blind 15 is suspended.
By lowering the window 0, an excellent effect is achieved in which the space between the double panes is made into a space where the blinds 11 and 15 do not exist, and the inside of the double panes can be easily cleaned.
