Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a lifting/lowering operating device for a Venetian blind built into a double-glazed window.

[Prior art] A Venetian blind headbox is installed in the upper horizontal frame of a double-glazed window, and a lifting cord pulled out from the headbox is hung on a slider that slides up and down within the vertical frame, and the slider is inserted from the outside of the window frame. Venetian blinds with built-in double glass windows, which can be operated to raise and lower the blinds, were first introduced in 1972.
It is known from No. 13043. The slider of the blind is equipped with stoppers on both sides, and the stoppers protrude under the force of a spring and press against the inner surface of the vertical frame of the window to stop the slider. However, when the slider is pinched up or down, the stoppers retract, allowing the slider to move freely. Can go up and down.

[Problems to be solved by the invention] Since the slider of the known device is slid by pinching the top and bottom with fingers, the sliding space of the slider provided in the vertical frame of the window has an opening width of about 20 mm. Therefore, the entire device can be seen from the outside, but it is not desirable for the appearance of the window to see the sliding of the lift cord and slider from the outside.

The present invention was made in view of the above, and its purpose is to provide a device in which the width of the opening for operating the slider is very narrow, so that the lifting cord, etc. cannot be seen from the outside. .

[Means for Solving the Problems] In order to achieve the above object, the features of the present invention are as follows: As shown in FIG. It is inserted into a gap having a rectangular cross section surrounded by an outer surface plate, a partition plate 14 parallel to the outer surface plate, and a protrusion 15 protruding from the outer surface plate and the partition plate in directions opposite to each other at right angles. The slider inserted into the gap so as to be able to move up and down has a box-shaped main body 21, a pulley 22 rotatably attached to the upper part of the main body, a lever 23 that is slidably supported on the main body, and a lever 23 that is slidably supported on the main body. A brake shoe 25 provided at one end of the lever and capable of abutting against the inner surface of the partition plate or the outer surface plate, an operation knob 27 provided at the other end of the lever that protrudes outward from the opening 16 of the outer surface plate, and the lever. It consists of a spring 28 that is interposed between the main bodies and presses the brake shoe against the inner surface of the partition plate or outer surface plate. A blind lifting cord 31 is hung on the pulley 22 of the main body 21.

[Operation] When the operating knob 27 of the slider 20 is pulled against the spring 28, the brake shoe 25 is separated from the inner surface of the partition plate 14 or the outer surface plate 13, so that the slider can be freely raised and lowered. Since the slider is connected to the blind lifting cord 31, when the slider is lowered, the bottom rail of the blind rises, and when the slider is raised, the bottom rail lowers. When the operating knob is released, the spring presses the brake shoe against the inner surface of the partition plate or outer surface plate and stops the slider from moving up and down, so the bottom rail of the blind stops.

[Example] The apparatus of the present invention will be described based on an example shown in the drawings.

As shown in FIGS. 1 and 2, four protrusions 15 protrude at right angles from the opposing inner surfaces of the outer surface plate 13 of the vertical frame 12 of the double-glazed window 10 and the partition plate 14, and there are four protrusions 15 having a rectangular cross section. A space extending vertically is divided. The main body 21 of the slider 20 is inserted into the space so as to be vertically slidable. A pulley 22 is installed on the top of the main body 21.
is rotatably supported. A lever 23 is pivotably supported on the lower side of the pulley 22, and a brake shoe 25 is provided at one end 24 of the lever. The other end 26 of the lever 23 passes between the opposing protrusions 15 and projects outward from the opening 16 of the outer plate 13.
A flat operating knob 27 is pivoted to the other end of the lever. One end of the coiled spring 28 is attached to the main body 21
, the other end is pinned to the lever 23, respectively,
The spring 28 pushes the lever 23 in the direction in which the brake shoe 25 comes into contact with the inner surface of the partition plate 14.

As shown in FIG. 3, the main body 21 is formed into a box shape, and the pulley 22 fits between both sides of the main body 21. The lever 23 is bent into a crank shape and the brake shoe 2
One end 24 with 5 is inside the main body 21, and the other end 24 is
6 are located on the outside of the main body 21, respectively. Spring 2
8 presses the lever 23 inside the main body 21. An operation knob 27 attached to the other end 26 of the lever 23 via a pin is rotatable up and down.

As shown in FIG. 1, the headbox 30 of the blind is attached to the upper horizontal frame 11, and the lifting cord 31 pulled out from the headbox hangs down inside the vertical frame 12 via guide rolls. The lifting cord 31 is hung on a pulley 22 on the upper part of the main body 21, and its end is fixed to a part of the head box 30 or a part of the glass window frame.

As shown in FIG. 4, the opening 16 in the vertical frame 12 of the double-glazed window 10 is narrow, and the space in which the slider slides inside is not visible from the outside. The other end 26 of the lever protrudes from the opening 16, and an operating knob 27 is provided at the other end.
Although the operation knob 27 is flat,
It can be placed along the outer surface plate 13. A slat 32 and a bottom rail 33 at its lowest end appear on the glass surface. The other end of the lifting cord is fixed to the bottom rail 33.

Next, the operation of raising and lowering the blind using the device of the present invention will be explained. When the operating knob 27 is pulled against the spring 28, the brake shoe 25 provided at one end 24 of the lever 23 separates from the inner surface of the partition plate 14, allowing the slider 10 to move up and down freely. When the main body 21 is lowered by pinching the operation knob 27, the blind lifting cord 31 is connected to the operation knob 2.
Since the bottom rail 33 is pulled twice as far as the descending distance of the operating knob 7, the bottom rail 33 rises twice as far as the operating knob descends, and the blind opens quickly. 10 is pulled up, the bottom rail is lowered and the blind is closed. The ascending distance of the operating knob 27 is half the descending distance of the bottom rail 33. When the operating knob 27 is released, the spring 28 releases the brake shoe 25.
is pressed against the inner surface of the partition plate 14 to prevent the main body 21 from moving up and down, so the bottom rail 33 stops.

Although the brake shoe in the embodiment contacts the inner surface of the partition plate, it is also possible to contact the inner surface of the outer plate.

[Effects of the invention] As mentioned above, in a double-glazed window equipped with the device of the invention, the main body of the slider that raises and lowers the blind cannot be seen from the outside, and the width of the opening in the vertical frame required for operating the slider is limited. Since it is narrow, it has a cleaner appearance compared to a conventional slider with an exposed body. Furthermore, since the width of the main body of the slider is small, the width of the vertical frame is also narrow as a whole, and the window glass portion can be made wider accordingly. Furthermore, the operation of raising and lowering the blind is extremely easy, as all you have to do is pull the operating knob and move it up and down.
