Description

[Detailed description of the invention] [Field of industrial application] The present invention consists of operating cords for lifting and lowering the slats (hereinafter referred to as lifting cords) and operating cords for rotating the slats (hereinafter referred to as lifting cords) hanging from positions close to each other in the head box of the blind. The present invention relates to a blind operating cord holding device that holds a rotating cord (hereinafter referred to as a rotation cord).

[Conventional technology]

In conventional cord-operated blinds, an elevating cord and a rotating cord hang from the headbox of the blind, and the slats are raised, lowered, and rotated by manually operating the lower end of the cord.

Generally, two lifting cords are provided, but for large blinds, two cords are not enough, and there are cases where three or more cords are installed, and the lifting and lowering operations are performed by pulling these cords together. Further, two rotation cords are provided, and by pulling one of them, the slat is rotated in one direction, and by pulling the other cord, the slat is rotated in the opposite direction. The mechanism itself for raising, lowering, and rotating these slats is well known, so a description thereof will be omitted.

[Problem that the invention attempts to solve]

In the blinds mentioned above, a type of blind was previously used in which the lifting cord was hung from near one end of the headbox and the rotating cord was hung from near the other end of the headbox, but this was inconvenient for operation. In many recent blinds, a lifting cord and a rotation cord are suspended from positions close to each other in the head box. However, if the lift cord and rotation cord are placed close to each other in this way, it may be difficult to know which cord to pull to perform the desired operation, or the cords may become entangled with each other. Problems such as cumbersome operation arise.

The present invention eliminates the drawbacks of the operating cords of conventional blinds, prevents the operating cords from getting tangled with each other, makes the operating cords easy to operate, and provides a blind with an excellent appearance. The present invention aims to provide a holding device for operating codes.

[Means for solving problems]

As a means to solve the above-mentioned problems, the present invention provides a device for holding operating cords for lifting and lowering slats and operating cords for rotating slats that hang down from positions close to each other in the head box of a blind. The operating cord for rotation is inserted into one hollow cylindrical body, and the operating cord for elevating and lowering passes through the hollow cylindrical body and hangs downward, and the end of the operating cord for rotation is slid vertically onto the hollow cylindrical body. A holding device for a blind operating cord is provided, which is characterized in that it is attached to a movably mounted slider.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.

FIG. 1 shows an embodiment of a blind provided with an operating cord holding device according to the present invention. In the figure, 1 is a head box, 2 is a plurality of slats supported horizontally at appropriate intervals above and below, 3 is a lower plate placed below the group of slats, and 4 is a ladder that supports the slats. Shows support code. In order to raise and lower the slats, two lifting cords 5 are provided, which extend vertically through the lifting cord insertion holes provided in each slat 2, and their lower ends are connected to the lower plate 5.
The upper part of the lifting cord is introduced into the headbox 1, extends horizontally to the right within the headbox, and exits downward near the right end of the headbox to form an operating cord for lifting and lowering.
Further, a rotation cord 6 for rotating the slat hangs down from near the end of the head box 1.
Both the lift cord 5 and the rotation cord 6 are led out of the head box 1 from a case 7 provided at one end of the head box 1, and therefore the operational parts of the lift cord and rotation cord are close to each other. It is arranged as follows.

As shown in FIGS. 2 and 3, a rotating shaft 8 is mounted inside the head box 1, and a drum 9 is attached to the end of the rotating shaft 8. The upper end of the rotating cord 6 is wound around the drum 9. Its both ends hang down from the case 7, and by pulling one cord, the rotation shaft 8 is rotated in one direction and the slat is rotated in that direction, and by pulling the other cord, the rotation shaft 8 is rotated in that direction. 8 in the opposite direction to rotate the slat in the opposite direction.

According to the present invention, both the lifting cord 5 and the rotating cord 6 are inserted into one hollow cylinder 10.
The lifting cords 5 pass through this hollow cylinder 10 and hang downwards, and according to a well-known structure, the two lifting cords are connected together and connected to one end of the lower plate 3 by a connecting cord. .

The hollow cylindrical body 10 is formed of a cylindrical body 11 made of, for example, transparent plastic, and sliders 12 and 13 are mounted thereon so as to be slidable in the vertical direction, as shown in FIGS. 4 and 5. Rotation code 6,6
is introduced into the hollow cylinder 10 from above,
One of them is attached to the slider 12, and
The other is attached to the slider 13. In the figure, 1
Reference numeral 4 denotes an operating knob that connects two lifting cords 5 together, and by pulling the lifting cords with this knob, the slats are raised and lowered.

In the embodiment shown in FIGS. 4 and 5, for example, hold the main body 11 of the hollow cylinder 10 with your left hand and turn the knob 1.
By operating the slider 12, you can control the raising and lowering of the slat.
Alternatively, the slat can be rotated in a desired direction by sliding it on the hollow cylindrical body 11 using the slats 13.

In the above device, the lifting cord and the rotating cord are combined in a hollow cylinder, preventing the cords from becoming entangled, and both operations can be performed in one place, making it very convenient in terms of operation. . Furthermore, the slider is regulated by the length of the hollow cylindrical cylindrical body, so that there is no possibility of straining the rotation mechanism by accidentally operating it excessively. However, since both operation cords are arranged in hollow cylinders, the appearance is also excellent.

The above embodiment has two parts on the cylindrical body of the hollow cylinder.
sliders 12 and 13 are provided, and a pair of rotation cords are respectively fixed to the sliders.
When one slider is operated, the other slider moves in the opposite direction via the rotation cord, and both sliders collide in the center of the cylindrical body, or both sliders come to the ends of the cylindrical body. At times, the movement of the slider is stopped and the rotation of the slat is stopped. However, in practice, it is also possible to operate the hollow cylinder in a hanging state due to the effect of gravity, without holding it in the hand. In this case, two slideable bodies are placed on the hollow cylindrical state body.
Instead of providing two sliders, one of the sliders may be fixed to the hollow cylindrical body. Such an embodiment is shown in FIGS. 6 and 7.

6A and 6B, a fixed cap 12' is attached to the upper end of the cylindrical body of the hollow cylinder 10', one rotating cord 6 is attached to this, and a slider 13 is slidably attached below the fixed cap 12'. An embodiment in which the other rotating cord 6 is attached to this is shown below. In addition, in FIGS. 7A and 7B, a fixed cap 13' is attached to the lower end of the cylindrical body 11 of the hollow cylinder 10'', a slider 12 is slidably attached above it, and a rotating cord is connected to the slider 12, respectively. and fixed cap 1
3' is shown.

FIG. 8 shows an example of the hollow cylindrical cylindrical body 11 described above, and FIG. FIG. 8(b) shows one in which a slit 15' extending over part of the length of the cylindrical body is formed. In the one shown in FIG. 8B, the movement of the slider is restricted by the length l of the slit 15'.

Fig. 9 shows various forms of the slider; A is a slider that surrounds the entire circumference of a hollow cylinder; 1 has a protrusion 16 protruding into the cylindrical body on its inner surface, and a rotating cord is fastened to this protrusion 16.

Figures 10 and 11 respectively show other embodiments of the present invention.

In Figures 10A and 10B, the hollow cylinder through which the lifting operation cord and rotation operation cord are inserted is not made into a hollow cylinder as in the previous embodiment, but is instead made into a flat cylinder, with a vertical partition wall in the center. The lifting cord 5 is passed through one side, the rotating cord 6 is passed through the other side, the end of one rotating cord 6 is fixed to the cylinder, and the other rotating cord 6 is attached to the slider 13. Show what you have.

Figures 11A and 11B are embodiments that are almost the same as those in Figure 10, but instead of providing a partition wall in Figure 10, the hollow cylinder is formed into a vertically long O-shape,
A lift cord 5 is passed through one side of the cord, and a rotation cord 6 is passed through the other side.

In the embodiment shown in FIGS. 10 and 11, the blind can be operated by holding the hollow cylinder with one hand and operating the slider with a finger.
