It will be attached directly to the housing. A rotating shaft 14 that connects the drum box elevating mechanism 10 and the crank handle 12 that operates the drum box elevating mechanism 10 from the indoor side, and a rotating shaft 15 that connects the screen elevating mechanism 11 and the ball chain 13 that operates the chamber from the indoor side. It is provided in a state of penetrating the housing.
Parts other than these are basically the same as the above-described integrated type sash, and the same parts are denoted by the same reference numerals and description thereof is omitted.

FIG. 8 shows an arrangement state of the rotary shaft 15 for connecting the screen lifting mechanism 11 for moving the screen 6 in and out of the screen drum box 5 to the ball chain 13 arranged on the indoor side. Note that the connecting structure between the lifting mechanism 10 and the crank handle 12 of the drum box 5 basically has the same structure with respect to the rotating shaft 14.
As shown in the figure, the rotating shaft 15 is rotatably inserted into a hollow portion of a cylindrical portion 16 attached to the housing in a penetrating state.

  As shown in FIG. 9A, the cylindrical portion 16 has a hollow cylindrical shape having a fixing flange 16c at the right end portion in the drawing, and an indoor side member 16a mounted on the indoor side of the housing, As shown in FIG. 9 (b), the outdoor member 16b has a hollow cylindrical shape slightly larger in diameter than the indoor member 16a, has a fixing flange 16d at the left end in the figure, and is mounted on the outside of the housing chamber.

  The indoor side member 16a is provided with a threaded portion 16e on the outer surface opposite to the flange 16c over the length of about half of the entire length, while the outdoor member 16b is provided on the inner surface opposite to the flange 16d. A female screw portion 16f that is screwed into the male screw portion 16e of the indoor side member 16a is provided over a length that is approximately half of the entire length.

And as shown in FIG.9 (c), it uses as the cylindrical part 16 by screwing the external thread part 16e of the indoor side member 16a in the internal thread part 16f of the outdoor side member 16b.
And since the full length of the cylindrical part 16 can be arbitrarily changed by adjusting the screwing depth at this time, it can respond easily to the change of the thickness dimension of a housing as a support member of the rotating shaft 15. Can do.

  In the integrated sash shown in FIGS. 1 to 4, the rotating shafts 14 and 15 are attached so as to pass through the upper frame of the window frame 1, but the cylindrical portion having such a structure is used. Application of 16 makes it possible to share parts even between window frames of different specifications.

  On the other hand, as shown in FIG. 10, the rotating shaft 15 is a rod-shaped member having a hexagonal cross section, and a female screw 15a is formed at the right end in the figure, and the screen 6 is a ball for lifting operation. A chain 13 can be attached.

The left end of the rotary shaft 15 in the drawing is fitted into a hexagonal hole formed in the input shaft of the gear box 11 a of the screen lifting mechanism 11, and the rotation of the rotary shaft 15 based on the operation of the ball chain 13. Is transmitted to the screen raising / lowering interlocking shaft 11b by the gear box 11a.
Note that the length adjustment of the rotating shaft 15 accompanying the change in the thickness dimension of the housing can be handled by cutting.

Similarly, the rotary shaft 14 that connects the lifting mechanism 10 of the screen drum box 5 and the crank handle 12 that operates the screen drum box 5 is also rotatably inserted by the cylindrical portion 16 including the indoor side member 16a and the outdoor side member 16b. Has been.
The tip of the rotary shaft 14 is also fitted into a hexagonal hole formed in the input shaft of the drum box lifting mechanism 10, and the rotation of the rotary shaft 14 by the operation of the crank handle 12 is the gear box. 10a is transmitted to the drum box lifting / lowering interlocking shaft 10b.

FIGS. 11 and 12 are for explaining the opening / closing operation of the screen 6 in the sash. FIG. 11 shows the drum box elevating mechanism 10 and the screen elevating mechanism 11, the screen drum box 5 and the screen 6. It is a schematic longitudinal cross-sectional view which shows the connection state of.
12A is a schematic horizontal sectional view of the upper part of the drive system showing the connection state between the drum box elevating mechanism 10 and the screen elevating mechanism 11 and the rotary shafts 14 and 15. FIG. 12B is a screen drum. FIG. 4 is a schematic horizontal cross-sectional view of the lower part of the drive system showing the positional relationship between the box 5 and screen 6 and the drum box lifting mechanism 10 and screen lifting mechanism 11.

As shown in these drawings, wire take-up pulleys 10c are fixed to both ends of the drum box lifting / lowering interlocking shaft 10b to which the rotation of the crank handle 12 is transmitted via the gear box 10a. Drum box elevating wires 10d and 10d are wound around these pulleys 10c, and the tips of these wires 10d are connected to both ends of the screen drum box 5, respectively.
That is, the screen drum box 5 is suspended from the pulleys 10c and 10c of the drum box lifting mechanism 10 by two wires 10d, and is moved up and down by the rotation of the drum box lifting and lowering interlocking shaft 10b. It has become.

  On the other hand, wire take-up pulleys 11c are similarly fixed to both ends of the screen raising / lowering interlocking shaft 11b to which the rotation of the rotating shaft 15 by the operation of the ball chain 13 is transmitted via the gear box 11a. The tips of the screen elevating wires 11d and 11d wound around the pulley 11c are connected to both ends of a bottom bar 6a attached to the lower end of the screen 6, respectively.

In order to fully open the screen 6, the crank handle 12 for raising and lowering the drum box is first rotated clockwise. The rotation of the rotating shaft 14 is converted into the rotation of the drum box lifting / lowering interlocking shaft 10b by the gear box 10a, and the drum box lifting wires 10d and 10d are wound around the wire winding pulleys 10c and 10c. Box 5 goes up.
When the screen drum box 5 reaches the upper end position, the crank handle 12 stops rotating when it hits the stopper, and the rotation operation of the crank handle 12 is stopped at that position.

At this time, the drum box 5 is housed in the drum box housing 8 and is not visible from the front side.
On the other hand, since the bottom bar 6a attached to the lower end portion of the screen 6 remains at the initial position, the screen 6 is fed out from the drum box 5 by the amount of the rise of the drum box 5.

Next, when the right side of the ball chain 13 is pulled downward, the rotation of the rotary shaft 15 is converted into the rotation of the screen lifting / lowering interlocking shaft 11b by the gear box 11a, and the screen lifting wire is connected to the wire take-up pulleys 11c and 11c. 11d and 11d are wound up, and the bottom bar 6a at the lower end of the screen 6 is similarly raised.
When the bottom bar 6 a is lifted, the screen 6 is wound up by the screen drum 5 a that is urged to rotate in the winding direction by a spring and is stored inside the screen drum box 5.

  Further, by continuing the operation of the ball chain 13 until the bottom bar 6a comes into contact with the lower end of the screen drum box 5, the screen 6 is wound around the screen drum 5a over the entire length and stored in the box 5, 6 can be fully opened.

  In this state, when the left side of the ball chain 13 is pulled downward, the screen lifting / lowering interlocking shaft 11b of the screen lifting / lowering mechanism 11 rotates in the reverse direction, whereby the wires 11d and 11d are unwound from the pulleys 11c and 11c. The bottom bar 6a of the screen 6 is lowered.

When the bottom bar 6a is lowered, the screen 6 is rewound from the screen drum 5a by its weight, and the screen 6 is fed out of the screen drum box 5 by the lowered amount. Then, the screen 6 is fully closed by continuing the operation of the ball chain 13 until the bottom bar 6a is stopped by the stopper provided on the guide member 7.
At this time, it is needless to say that the operation of the ball chain 13 is stopped halfway, so that the bottom bar 6a stays at the intermediate position, so that only the lower side of the window is opened.

When the crank handle 12 for raising / lowering the drum box is rotated counterclockwise in the fully closed state of the screen 6, the drum box raising / lowering interlocking shaft 10b of the drum box raising / lowering mechanism 10 rotates in the reverse direction, and the wires 10d, 10d from the pulleys 10c, 10c. Is rewound, and the screen drum box 5 starts to descend.
When the drum box 5 is lowered, the screen 6 is wound by the screen drum 5a that is urged to rotate in the winding direction, and the drum box 5 is stored in the screen drum box 5 by the lowered amount, and the handle is operated at a desired position. By stopping, it becomes a half-open state in which only the upper side of the window is opened.

In this state, when the right side of the screen lifting / lowering ball chain 13 is operated downward, the bottom bar 6a of the screen 6 is wound up by the pulleys 11c and 11c of the screen lifting mechanism 11 and the screen 6 is moved upward. Is stored in the drum box 5.
As a result, the upper and lower portions of the window can be opened simultaneously, and only the central portion of the window can be covered with the screen 6.

Thus, in the sash of the present invention, the screen 6 can be moved to a desired position, and not only the lower side of the window but also the upper side of the window or the upper side and the lower side of the window can be opened simultaneously. it can.
Therefore, by adjusting the position of the screen 6 in conjunction with the opening and closing of the shoji 2 and 3, the lighting, wind-collecting and ventilating properties can be achieved while sunshading and blindfolding according to the direction of the sun and the line of sight from the outside. It can be adjusted over a wide range.

In the above-described embodiment, an example in which the roll-up roll screen 6 is used as the shielding material has been shown. However, the shielding material used for the sash and the blind according to the present invention is limited to a winding-type material. Instead, it is possible to use a foldable type or a number of blades.
In the present invention, the “shielding material” is not limited to an opaque material as long as it has some light shielding properties and can be shaded from the outside or from the outside. Various materials such as a translucent or lace-like one having a pattern or a pattern can be used.

  Moreover, in the above-described embodiment, an example in which the shojis 2 and 3 that move up and down are fitted into the window frame 1 is shown. It is possible to adopt various types of shoji, such as turning the upper and lower portions into shoji.

  Further, the drum box elevating mechanism 10 and the screen elevating mechanism 11 are not limited to the above-described wire winding type, and various mechanisms can be employed, for example, as shown in FIGS. 13 and 14. A simple geared cable system can also be adopted.

  13A is a schematic front view showing a lifting mechanism in a geared cable type blind, and FIG. 13B is a schematic longitudinal sectional view thereof. 14A is a schematic horizontal cross-sectional view at the upper part of the drive system, and FIG. 12B is a schematic horizontal cross-sectional view at the lower part of the drive system.

In the figure, geared cables 18a each having a structure in which a wire is spirally wound around a core cable are fixed to both ends of the screen drum box 5, respectively.
These two geared cables 18a are rotatably arranged inside screen drum box lifting cable connectors 18b, 18b provided on the left and right sides of the screen drum box storage rod 8 (not shown), and are therefore screw members (not shown). ).

When the rotation of the crank handle 12 for raising / lowering the drum box (not shown) is transmitted to the female screw member in the cable connector 18b on the right side in the drawing via the operation cable 18c, the left side in the drawing is moved by the interlocking shaft 18d for raising / lowering the drum box. The female screw member also rotates in synchronization with this. When the female screw members rotate, the geared cables 18a and 18a meshing with the female screw members are pulled up, and the screen drum box 5 moves up and down together with the geared cables 18a and 18a while maintaining the horizontal state.
The upper end side of the geared cable 18a protruding from the cable connector 18b when the drum box 5 is raised is guided into a pipe 18e connected to the cable connector 18b. Is configured.

  On the other hand, the same geared cable 19a is fixed to both ends of the bottom bar 6a of the screen 6, and these two geared cables 19a can be rotated inside screen lifting cable connectors 19b and 19b provided on the left and right sides. Therefore, the screw members (not shown) are engaged with each other.

  When the operation of the screen lifting / lowering ball chain 13 (not shown) is transmitted to the female screw member of the cable connector 19b on the left side of the drawing via the cable 19c, the right side screw screw member in the drawing is moved by the screen lifting / lowering interlocking shaft 19d. The bottom bar 6a is moved up and down together with the geared cables 19a and 19a by rotating in synchronization with this, and the lifting mechanism 19 of the screen 6 is constituted by these.

In such a drum box elevating mechanism 18 and screen elevating mechanism 19 as well, by operating the crank handle 12 and the ball chain 13, the elevating and lowering of the screen drum box 5 and the screen 6 appearing from the drum box 5 can be controlled. Can do.
Therefore, only the arbitrary position of the window can be covered with the screen 6, and the lighting condition and the wind condition can be suitably adjusted while blindfolding and shading similarly.
