[Prior art]

In general, in blind sashes in which multiple levels of slats are supported from the headbox via ladder cords, a portion of the vertical stile, for example, a handle provided on the vertical stile, is attached to the next side to adjust the angle of the slats. An angle adjustment mechanism is provided as shown.

That is, an operation dial is provided in the handle, and an angle adjustment rod is provided that passes through the vertical stile from one side of the head box, and is connected to the operation dial to adjust the angle of the slat as the operation dial rotates. Make adjustments. A notch is provided in the handle, and an angle adjustment cord is provided extending from one side of the head box into the stile, a portion of which is exposed from the notch, and the exposed portion can be manipulated to adjust the angle of the slat. Make adjustments.

(Problems to be solved by the invention) However, the above structure has the following problems.

That is, in the structure of (2), since the operation dial is exposed on the surface of the handle, not only is the appearance unfavorable, but the structure itself is complicated.

In this structure, since the notch becomes large, it is not only unfavorable in terms of appearance, but also
There was a risk that the function of the handle itself would be inhibited.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an operating device for an angle adjustment cord in a sash with a blind that is pleasing in appearance and has good operability.

Structure of the invention (means for solving the problems) Therefore, in order to solve the above problems, the present invention has the following features:
The angle adjustment cord hanging down from the head box is guided into the vertical stile of the sash, and the angle adjustment shaft inside the head box is rotationally driven via the angle adjustment cord by the angle adjustment cord operating device attached to the stile. In a sash with a blind for adjusting the angle of the slats, a handle attached to the vertical stile is provided with a long hole extending vertically, and a cover plate is provided with the handle that moves vertically along the surface while always covering the long hole. A control knob is provided on the surface of the cover plate, and a transmission section located inside the vertical stile is connected to the back side through the elongated hole, and an angle adjustment cord is connected to the transmission section. ing.

(Function) With the above means, by operating the operating knob to move the cover plate provided on the handle so as to be movable up and down, the angle of the slat can be arbitrarily adjusted. At this time, even if the cover plate moves up or down, it covers the long hole provided in the handle, so the long hole will not be exposed.

(Example) An example embodying this invention will be described below with reference to the drawings.

The double glass sash 1 shown in FIG. 6 has a pair of sashes 1a and 1b as sliding doors, and a blind 2 is built in between the double glass windows of each sash 1a and 1b.

In the blind 2, multiple tiers of slats 4 are suspended and supported from a head box (described later) disposed within the upper stile 3 of each sash 1a, 1b.
The angle can be adjusted by operating the operating device of the handle 6 provided on the vertical stile 5 on the outside of the sashes 1a and 1b, and the other side of the vertical stile 5 is open.
Each slat 4 can be raised and lowered by raising and lowering the bottom rail 9 by manipulating the lifting cords 8a and 8b exposed therefrom.

Next, the blind 2 will be explained with respect to the sash 1a. As shown in FIG. is supported by Ladder cord support devices 12 are disposed near both sides of the head box 10 in the head box 10, and the angle adjustment shaft 11 passes through a ladder cord winding shaft (not shown) in the support device 12 to take up the winding shaft. It is designed to rotate as one.

The ladder cord 13, which supports the slats 4 in multiple stages vertically, has its upper end supported by the winding shaft. When the angle adjustment shaft 11 is rotated in the forward and reverse directions, the angle of each slat 4 can be adjusted within a range of about 90 degrees in the forward and reverse directions from the horizontal state via the winding shaft and the ladder cord 13. It's becoming like that.

A drive device 14 is attached to one end of the head box 10 for raising and lowering the slats 4 and adjusting the angle thereof.By operating an angle adjustment cord 15 hanging from the drive device 14, the angle adjustment shaft 11 is rotated and the slats are moved. 4 angle adjustments are possible.
Further, two lifting cords 8a and 8b for lifting and lowering the slat 4 have one end fixed to one end of the bottom rail 9, and are connected by a guide roller 16 placed at the lower end of the vertical stile 5 and rotatably supported. The slats 5 are guided upwardly within the vertical stile 5 and guided downwardly by the guide roller 17 at one end of the headbox 10 by the driving device 14, passing through one end of each slat 4 and having the other end connected and fixed to the bottom rail 9. The other lifting cord 8b is guided below the headbox 10 by a guide roller 18 at the other end of the headbox 10, passes through the other end of each slat 4, and the other end is connected and fixed to the bottom rail 9.

And the lifting cord 8 exposed in the 5 directions of the vertical stile.
By operating a, 8b upward or downward, the bottom rail 9 can be raised or lowered, and the slat 4 can be raised or lowered. Note that the lifting cords 8a, 8b are divided into upper and lower parts between the drive device 14 and the guide roller 16, and are connected by a connector 19, so that the length of the lifting cords 8a, 8b can be adjusted at this portion. I'm starting to be able to do it. The driving device 14 and devices in its vicinity can be appropriately selected from conventionally proposed devices, and since they are not the gist of the present invention, their details will be omitted.

As shown in FIG.
The cord guide 3 is located at the center of the vertical stile 5 in the vertical direction.
You are guided to 2. As shown in FIGS. 3 and 4, the cord guide 32 is formed by bending a long steel plate, and its central part is fixed to the vertical frame 5 with a screw 33, and its lower part is bent diagonally. The tip portion 34 protrudes downward and is bent inward in an arc shape near the side edge of the vertical stile 5. The lifting cords 8a and 8b are elastically supported near the side edges of the vertical stile 5 by their tip ends 34 in the vicinity of the cord guide 32.

A support shaft 35 for hanging the angle adjustment cord 15 is provided on the upper part of the cord guide 32. The angle adjustment cord 15 hanging from the drive device 14 has an endless shape, and its lower end is connected to the support shaft 35.
It is movably hung. Angle adjustment cord 1
5, a ball chain 36 is connected to a part thereof, as shown in FIG. As shown in FIG. 5, the ball chain 36 is made up of balls 36a connected by wires 36b, and is always located behind the handle 6 of the vertical stile 5.

Next, the structure of the operating device of the present application will be described in detail. As shown in FIGS. 1 and 2, the handle 6 is provided with a long hole 37 extending in the vertical direction at the center thereof. Next, reference numeral 3a denotes a cover plate, which is disposed within the handle 6 so as to be able to move vertically along the surface with the long holes 37 always increasing.
is installed protrudingly. Further, on the back side of the cover plate 39, there is a transmission part 42 located inside the vertical frame 5 through the elongated hole 37.
are connected by screws 41, and buffer members 43 formed in a flat plate shape made of soft synthetic resin are attached to both upper and lower ends of the back side of the cover plate 39. Therefore, even if the operating knob 7 is operated to move the cover plate 39 either up or down, the elongated hole 37 is prevented from being exposed. This prevents the operation member 40 and the handle 6 or the cover plate 39 from rubbing against each other and producing unpleasant sounds when the handle is turned.

Further, the transmission section 42 is formed in the shape of a hollow box, and a locking groove 44 is formed in the transmission section 42 through which only the wire 36b portion of the ball chain 36 can be inserted. As shown in FIG. 4, when the wire 36b of the ball chain 36 is inserted into the locking groove 44, the balls 36a engage with each other at the top and bottom of the transmission section 42, and the transmission section 42 and the ball chain 36 are integrated. It is possible to move up and down by connecting the
In this state, if you move the operation knob 7 up or down, the cover plate 39
The angle adjustment shaft 11 is rotated via the transmission section 42 and the ball chain 36. When the operating knob 7 is located at the center of the elongated hole 37, the slat 4 is held horizontally, and if the operating knob 7 is moved upward or downward from the center along the elongated hole 37, the slat 4 The angle can be adjusted in 90 degree increments both forward and backward from the horizontal direction.

Next, the operation of the blind 2 configured as described above will be explained.

When the blind 2 attached to the sash 1a operates the lifting cords 8a and 8b exposed on the side of the vertical stile 5, the bottom rail 9 will be raised and lowered, each slat 4 will be raised and lowered, and the lifting cord 8
If you let go of a and 8b, the lifting cords 8a and 8
Since the movement of b is prevented, this slat 4 is suspended and supported at a desired position, as in the conventional case.

To adjust the angle of the slats 4 of the blind 2, move the cover plate 39 along the elongated hole 37 by operating the operating knob 7 inside the handle 6 in the vertical direction. The angle adjustment cord 15 is moved via the cable 36, the angle adjustment shaft 11 is rotated, and the angle of each slat 4 is adjusted in the same phase via the ladder cord 13 and a winding shaft of the ladder cord (not shown).

In order to adjust this angle, use the operation knob 7.
Even if the cover plate 39 is moved up and down by operating the cover plate 39, the elongated hole 37 is always covered by the cover plate 39 and is never exposed on the surface side of the sash 1, allowing the slat to be moved without spoiling the beauty of the sash 1a itself. Now comes the time to adjust the angle in step 4.

Further, since a buffer member 43 made of soft resin is provided on the back surface of the cover plate 39, it is possible to prevent the cover plate 39 and the handle 6 from rubbing against each other and generate abnormal noise, and also to improve the operation feeling. can be improved.

In this embodiment, a buffer member 43 is provided on the back surface of the protruding piece 39, but this buffer member 43
does not necessarily need to be provided, and even if provided, it is not necessarily necessary to use soft synthetic resin.
That is, rubber, cork, or the like may be used as long as it can improve operability and prevent abnormal noises.

Effects of the invention As detailed above, the present invention has an excellent appearance because the long hole provided in the handle can be covered and hidden even if the cover plate is moved up or down by operating the operation knob. It has the excellent effect of becoming a thing.
