Description

[Detailed explanation of the invention] [Purpose of the invention] "Field of industrial application" This invention is a window that is equipped with shoji inside and outside, and the shoji is integrated to form double glass. It concerns windows with blinds placed between them.

"Prior art" Figure 5 is a front view of a conventional window seen from the inside.
FIG. 6 is a plan view of FIG. 5. In this window, an inner shoji 8, in which a glass 7 is fitted into a stile 6, is pivoted by a hinge 5 to an outer shoji 4, in which a glass 3 is fitted into a stile 2, which is assembled on all four sides within the frame of an opening frame 1. At all times, the outer shoji 4 and the inner shoji 8 are stacked and fixed. A hanging blind 9 is provided between the inner and outer shoji 4 and 8.

The inner shoji 8 can be rotated inward around the hinge 5, and the space between the inner shoji 8 and the outer shoji 4 is opened, and the glasses 3 and 7 of the inner and outer shoji are opened.
The opposite surface can be cleaned. With the inner and outer shoji 4 and 8 stacked, rotate the handle 10 90 degrees and pull it toward the inside to open inward, and handle 1
The inner and outer shoji 8 and the opening frame 1 are connected to each other by a connecting device that allows the inner and outer shoji 4 and 8 to be folded inward while stacked on top of each other by rotating the shoji 0 by 180 degrees and pulling it upward (the connecting device is not shown).

7 and 8 are a plan view and a front view of a conventional blind, and FIG. 9 is a partially sectional side view of FIG. 3. The head box 11 is long from side to side, and has a groove-shaped cross section with an open top. A lead screw 12 is fixed to one end of the head box 11 parallel to the longitudinal direction of the head box 11, a nut 13 is screwed into the lead screw 12, and a cord wound parallel to the longitudinal direction of the head box 11 is attached to the nut 13. One end of the take-up drum 14 is fixed. The other end of the cord winding drum 14 is rigid in the rotational direction and movable in the axial direction so that rotation can be transmitted to the output shaft end of a gearbox 15 in which a pair of screw gears are supported. . The gearbox 15 is housed in the headbox 11 and is fixed to the headbox 11. gearbox 1
The output shaft of 5 is coaxial with the cord winding drum 14, and the input shaft 16 faces toward the inside of the window.

The unwound side of the cord 17, which is wound around the cord winding drum 14 with its end fixed, is inserted through the long hole 18 in the width direction at the widthwise center of the bottom of the head box 11, and is inserted into a large number of parallel cords. Slut 19
It is fixed to the bottom rail 21 by being loosely inserted through a long hole at the center in the width direction. A ladder cord 22, which connects both ends of each slat 19 in the width direction at equal intervals when stretched, is wound approximately 180 degrees above the cord winding drum 14.

The length of the head box 11 is shorter than the length of the slats 19, and the lengths of the slats 19 are such that both ends thereof fit between the frames of the inner and outer shoji 4 and 8.

The input shaft 16 of the gearbox 15 extends into the room by passing through the upper stile of the inner sash 8 at a position above the glass surfaces 3 and 7 shown in FIG. be.

By pulling either side of the operating cord 30, the input shaft 16 of the gearbox rotates and its output shaft rotates the cord winding drum 14. When the cord 17 is wound around the cord winding drum 14, the bottom rail 21 rises and the slat 1
9 are folded sequentially from the bottom. When the cord 17 is unwound from the cord winding drum 14, the bottom rail 21 is lowered and the slats 19 are gradually spaced apart from each other from above. And when moving up and down, the ladder cord 22
is moved by the frictional force with the cord winding drum 14, and one of the ladder cords 22 connected to both sides of the slat 19 in the width direction is pulled up and the other is lowered, so that the slat 19 is tilted. Therefore, when the slats 19 are moved up and down, the ends of the slats 19 in the width direction overlap each other. Therefore, unless you want to fold the whole thing up to the top, after pulling either one of the operating cords 30 to move it up and down, pull the other one a small distance from the side you have been pulling until now. The winding drum 14 is slightly reversed,
The side of the ladder cord 22 that has been pulled up until now is lowered, and the side that was lowered until now is pulled up, or conversely, when descending, the lower edge rises and the upper edge descends, so that the slat 19 is level. The slats 19 are now in an open state. When all of the slats 19 are folded to the highest level, when the highest slat 19 is lifted by the bottom rail 21, the portion of the ladder cord 22 that is wound around the cord winding drum 14 from the highest slat 19 becomes loose and the cord becomes loose. Frictional sliding with the winding drum 14 is released, and the slat 19 pushed up by the bottom rail 21 collides with the horizontal lower surface of the head box 11 and remains horizontal.

When the cord 17 is wound around the cord winding drum 14, the cord 17 is rotated and simultaneously moved in the longitudinal direction by the nut 13 and the lead screw 12, so the cord 17 is wound around the cord winding drum 14 in a spiral shape. It is starting to be taken.

In another conventional example of the above blind, the length of the headbox 11 is the same as the length of the slat 19, but the position of the gearbox 15 is as explained above, and the length of the slat 19 from the input shaft 16 of the gearbox 15 is the same. The distance to the end in the direction is the same as described above.

``Problem that the invention aims to solve'' In such windows with blinds between the double panes, the distance from the input shaft of the gearbox to the longitudinal end of the slat is long, so the hanging position of the operating cord is difficult. However, the surface of the glass 3 and 7 of the inner and outer shoji is not aesthetically pleasing.

This invention solves the above-mentioned problems in windows with blinds between double-paned glass by hanging operating cords outside the glass surface, and creates an aesthetically pleasing blind operating pulley. The purpose is to provide equipment.

[Structure of the idea]

``Means to solve the problem'' This idea was to stack inner and outer shoji, each with a glass inlay, to form a single shoji with double glass, and place blinds in the space between the inner and outer shoji. The blind operating device includes a gear box, an operating shaft, an operating pulley, and an operating cord, the gear box is disposed above the space between the inner shoji and the outer shoji, and the operating shaft is connected to the inner shoji. One end is connected to the gear box and the other end is connected to the operating pulley, and the operating cord is hung on the operating pulley, and the hanging position of the operating cord hung on the operating pulley is This blind operating device is characterized in that a gearbox, an operating shaft, and an operating pulley are arranged so as to be aligned with the rigid frame when viewed from the outside.
