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 lift cord pulled out from the headbox is hung on a slider that slides up and down within the vertical frame, and the slider is attached to the outside of the window frame. Venetian blinds with built-in double-glazed windows, which can be raised and lowered by operating from
-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] The slider of the known device brakes by bringing a stopper into contact with the inner surface of the partitioned vertical frame, but the shape and dimensions of the partition within the vertical frame depend on the window frame. Because of the difference, there was a problem in that the slider and stopper had to be manufactured to match each window frame.

The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a blind lifting/lowering operating device that can be used regardless of the internal partition of the vertical frame of a double-glazed window.

[Means for Solving the Problems] In order to achieve the above object, the features of the present invention are as shown in FIG.
A wire 15 is stretched inside the opening 16 of the vertical frame 12, the wire is passed through the slider 20, and the slider is provided with a collection chuck as a stopper that engages with the wire and freely brakes the vertical movement of the slider. The knob 27 for operating the collection chuck is made to protrude outward from the opening.

[Function] Connect the wire 15 to the collector 25 of the collector chuck.
When the collet 25 is pushed up from the collet hole 23 with the knob 27, the collet 25 becomes loose and the slider 20 can move up and down freely, and the knob 2
When 7 is released, the collet 25 grips the wire 15 and the slider 20 is braked. Since the bottom rail is connected to the slider 20 via the lift cord 31, it stops when the slider 20 is braked, and can move up and down when the slider 20 becomes free.

[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 wire 15 is stretched inside the opening 16 of the vertical frame 12 of the double-glazed window 10, and a collet 25 is passed through the wire. The main body 21 of the slider 20 is formed in a U-shape, and the wire 15 passes through collets 23 and pilot holes 24 arranged vertically. A collet 25 through which the wire 15 is passed is inserted into the collet hole 23. Lifting cord 31 to slider 20
A pulley 22 for hanging is rotatably supported. The lifting cord 31 is pulled out from the head box 30 of the blind fixed to the upper horizontal frame 11 and hangs down inside the vertical frame 12 via guide rolls. Lifting code 31
The end of the head goes around the pulley 22 and is fixed to a part of the head box 30. The width of the main body 21 is wider than the opening 16, and the front surface of the main body 21 has an outer surface plate 1 forming the opening 16.
3, the rear surface and the side surfaces are in contact with the inner surface of the partition plate 14, respectively. A protrusion 36 is provided that extends outward from the front surface of the main body 21 through the opening 16, and a knob 27 is rotatably attached to the protrusion via a pin 37. As shown in FIG. 2, by turning the knob 27, it can be made to fit snugly along the outer surface plate 13 in front of the vertical frame. A tab 38 is fitted onto both the pin 37 and the wire 15 between the collector hole 23 and the pilot hole 24 of the main body 21. A lever 26 is fitted under the tab 28 of the pin 37, and the lever is attached to the knob 27 so as to be vertically slidable. A spring 29 is interposed between the lever 26 and the tab to press the lever 26 downward.

When the lever 26 is raised as shown by the arrow in FIG.
Since the collet 25 is pushed out, the collet 25 becomes slack.

As shown in FIG. 4, a knob 27 is pivoted to a protrusion 26 of a slider 20 extending outward from an opening 16 in the front of the vertical frame 12 of the double-glazed window 10.
Since the knob 27 is flat, it can be placed exactly along the front. The slats 32 of the blind and the bottom rail 33 to which the other end of the lifting cord is fixed appear on the glass surface.

Next, the blind raising/lowering operation 12 will be explained.

When the knob 27 is lowered, the slider 20 descends,
The collet 25 comes out from the upper hole 23 and loosens the slider 2.
It descends with 0. As the slider 20 descends,
Since the pulley 22 of the slider 20 pulls the lifting cord 31 twice as far as the downward distance of the knob 27, the bottom rail 33 rises twice as far as the downward distance of the knob 27, and the blind opens quickly.

When the knob 27 is released, the slider 20 is pulled up by the weight of the bottom rail 33, but since the collet 25 enters the collet hole 23 and is tightened to the wire 15, the slider 20 is prevented from rising and the bottom rail 33 is stopped.

When lever 26 is raised by grasping knob 27, tab 28 pushes up and loosens collector 25, as shown in FIG.
, the slider 20 can freely move up and down. Then, when the knob 27 is raised, the lifting cord 3
1 slackens by twice the lifting distance of knob 27,
The bottom rail 33 is lowered twice as far as the knob 27 is raised and the blind is quickly closed.

At least the front surface 33 of the slider 20 is always in contact with the inner surface of the outer surface plate 13 in which the opening 16 of the vertical frame 12 is provided, so that the posture of the slider 20 is always stable while it is stopped and when it is moving up and down.

[Effects of the invention] As described above, the device of the invention provides a wire along the opening in the vertical frame of a double-glazed window, moves the slider up and down along the wire and the inner surface of the outer panel that forms the opening, and Since the slider is locked to the wire and stopped by operating the stopper provided on the slider, unlike the conventional method in which the slider is locked to the inner surface of the vertical frame, the shape and dimensions of the slider can be adjusted to the inner surface of the vertical frame. An excellent effect can be obtained in that devices having the same shape and dimensions can be installed in various vertical frames without the need for matching.
