Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an improvement of a device for adjusting the angle of the slats of a Venetian blind built into a double-glazed window. This device involves fixing an upper car on the shaft end of a tilting shaft, attaching a lower car to a vertical frame of a glass window, and adjusting the inclination of the slat by rotating an endless band hung over the upper car and the lower car.

[Prior art] A blind headbox supported on the upper horizontal frame of a double-glazed window, an upper wheel fixed to the shaft end of a slat rotatably supported by the headbox, and a blind headbox supported on the upper horizontal frame of a double-glazed window. A device comprising a dismounting vehicle attached to the vehicle, and a belt placed over the ascending vehicle and the dismounting vehicle, and which rotates the belt to adjust the angle of the slats, is known from Japanese Utility Model Application No. 58-79696.
The device had a fixed dismount, so if the belt stretched and loosened, the length of the belt had to be adjusted. Furthermore, since the slat angle is adjusted by raising and lowering the lifting plate that is integrated with the belt, it is not possible to keep the operating lifting plate at a fixed position.

[Problems to be solved by the invention] The invention was made in view of the above, and its purpose is to rotate an endless band provided within the vertical frame of a double-glazed window with a built-in blind. It is a device for adjusting the angle of the slat by adjusting the angle of the slat, and it is possible to easily adjust the extension of the endless belt, and
To provide a slat angle that can be adjusted by operating a dial at a fixed position.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the features of the present invention are provided by means of an upper wheel fixed to the end of the tilting shaft of the slat and installed inside the vertical frame of the glass window. In the slat angle adjustment device, which consists of a lower car and an endless band hung over the upper car and the lower car, the lower car is bearinged on a slider, the slider is inserted into the base so as to be movable up and down, and the base is fixed to the vertical frame. , a slope is provided on the slider, a long hole or long groove extending in the vertical direction is provided on the slope, a bolt is passed through the long hole or long groove from the front of the base, and the bolt has a slope that engages with the slope of the slider. This consisted of fitting a nut, providing a stopper for the nut, fixing the dial coaxially to the vehicle, and exposing a portion of the dial to the outside from the front of the base.

[Function] A part of the dial is exposed from the front of the double-glazed window, so you can turn the dial with your fingers. When the dial rotates, the endless band rotates and turns the tilting shaft, which tilts the slat and adjusts the angle.

When the endless belt is stretched and loosened, when the bolt is tightened, the slope of the slider is pushed by the slope of the nut and the slider descends, increasing the distance between the upper and lower wheels and the endless belt becomes properly tensioned again. .

[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, a blind headbox 30 is attached to the upper horizontal frame 11 of a double-glazed window 10, and a tilting shaft 31 is rotatably supported within the headbox. Tilt axis 3
A drum 32 is attached to 1 so as to rotate together, and the upper end of a ladder cord 33 is hung on the drum. Ladder code 33 is head box 30
The slats 34 are suspended from the inside of the glass surface to support a number of slats 34. An upper wheel 35 is attached to the end of the tilting shaft 31, and a ball chain 15 as an endless band is hung on the upper wheel.

The ball chain 15 hangs down inside the vertical frame 12 and rotates around the alighting car 21. A dial 23 having a larger outer diameter than the alighting car 21 is coaxially fixed to a rotating shaft 22 of the alighting car 21. The rotating shaft 22 is supported by a slide 24, and the slider is inserted into the base 20 so as to be vertically slidable.

A slope 25 tapered upward and inclined toward the front side is formed on the lower back surface of the slider 24, and a long groove 26 is provided in the center of the slope to extend vertically. A bolt 27 is passed through the long groove from the front of the base 20, and a nut 29 having a slope 28 that engages with the slope 25 is hung on the bolt. A rotation stopper 19 for the nut 29 is provided on the base 20, but a part of the nut may be fitted into a long groove or a slider to prevent rotation. dial 2
Part 3 is exposed on the front side and can be operated with your fingers.

Next, the operation of the device of the present invention will be explained. When the dial 23 exposed on the front side of the double-glazed window 10 is turned in one direction with a finger, the coaxial lower car 21 rotates and the ball chain 15 rotates in one direction. tilt axis 31
rotates and the slat 34 tilts to one side. When the dial 23 is turned in the opposite direction, the slat 34 is tilted in the opposite direction, so the angle of the slat can be easily adjusted by turning the dial 23 with a finger.

The ball chain 15 stretches and becomes loose during use, but as shown in Figure 3, when the bolt 27 is tightened, the slope 28 of the nut 29 pushes the slope 25 of the slider 24, so the slider 24 is moved as shown by the arrow. As in, descend. As a result, the distance between the up and down cars 21 becomes longer, and the ball chain 15 is stretched with appropriate tension.

[Effects of the invention] As mentioned above, the device of the invention not only allows you to easily adjust the slat angle of the blind built into a double-glazed window by operating the dial, but also allows you to rotate the tilt axis of the slat. Even if the endless belt of a ball chain or the like is loosened, the excellent effect of tensioning the endless belt can be obtained by simply turning the bolt whose head is protruding from the front.
