Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a pull-up curtain, and more specifically, to a pull-up curtain that can partially change the height of the curtain hem when it is rolled up. be.

[Conventional technology]

A roll-up curtain that allows you to partially change the height of the hem of the curtain was developed in 1986, for example.
This is proposed by Publication No. 126882. In this method, several lifting cords are attached vertically at regular intervals in the width direction of the curtain, and the lower end of each lifting cord is connected to the lower edge of the curtain, and the other upper end is connected to the headbox from the bottom surface of the headbox. After guiding the cord horizontally inside the headbox, it is led out from one end of the headbox and suspended downward through a stopper, and these several lifting cords are fixed to one knob, and the cords can be selectively controlled. The structure is such that several of the lifting cords can be distinguished from other lifting cords by their material, structure, color, etc. for easy towing operations.

By the way, this type of pull-up curtain has a feature in that it is possible to partially adjust the hem of the curtain to the desired height by operating an arbitrary lifting cord. ,
On the other hand, since all the lifting cords hang down from the stopper installed at the lead-out part from the head box, the larger the width of the curtain, the greater the number of lifting cords, and it is easy to distinguish between the lifting cords. Even if it were possible, it would be very complicated to select and operate any lifting cord from a large number of lifting cords, and the fact that many lifting cords were hanging on the sides of the curtains would be visually difficult. There was also the problem that it was unsightly.

[Purpose of invention]

The present invention solves the above-mentioned drawbacks and allows the height of the hem of the curtain to be partially raised to different heights by simply operating a single operation cord, making it easy to operate. The purpose is to provide a fold-up curtain that is also excellent in design.

[Summary of the idea]

The feature of the pull-up curtain according to the present invention is that the upper ends of a plurality of lifting cords hung at appropriate intervals from the head box for pulling up the curtain can be wound onto a winding drum installed inside the head box. Among the winding drums that are connected and wind the respective lifting cords, at least one winding drum has a different winding diameter from the other winding drums.

In the above configuration, the diameter of the plurality of winding drums is
It is possible to set and change the settings as appropriate according to the wishes of the person using the folding curtain. For example, when the user wishes to raise the height of the center part of the curtain higher than the height of the curtains on both sides. In this case, the winding diameter of the internal winding drum located at the central portion of the head box in the longitudinal direction may be made larger than the diameter of the winding drums located at both ends in the longitudinal direction. The difference in diameter of the winding drums of different diameters may be selected depending on the difference in height of the hem when rolled up.

In order to preferably configure the raised curtain of the present invention, a cylindrical drum member forming a winding drum of a predetermined diameter is fitted onto a common rotating shaft for rotating the winding drum by an external operation. It is better to This is because, according to such a configuration, by appropriately selecting and using cylindrical drum members having different diameters, it is possible to configure folded up curtains with different folded states as required.

〔Example〕

Hereinafter, a description will be given based on the embodiments shown in the drawings.

FIG. 1 is a front view showing an embodiment of the rolled-up curtain according to the present invention, showing the state in which the curtain is completely lowered. In the figure, 1 is the head box, 2
a, 2b, . . . are lifting cords, 3 is a curtain, 4 is a lifting operation unit, and 5 is an operation code.
The lifting cords 2a, 2b, etc. of this example are shown in FIGS. 3 to 4.
As shown in the figure, its lower end is connected to the connecting parts 6a, 6b, etc. provided on the lower edge of the curtain, and its upper end is guided upward along the back surface of the curtain, and introduced into the head box 1 from the lower surface of the head box, and then inserted into the head box. As shown in FIG. 3, it is connected to winding drums 7a, 7b, . In this example, 4
Of the two winding drums, the two inner winding drums 7
b has a diameter larger than that of the outer winding drum 7a, and the winding diameters of the lifting cords are made different between the outer lifting cord 2a and the inner lifting cord 2b. Therefore, by operating the operating cord 5 shown in FIG.
a, 2b... are wound onto the winding drums 7a, 7b..., the winding amount of the lifting cord is smaller on the outer winding drum 7a, and more on the inner winding drum 7b. As a result, as shown in FIG. 2, the amount by which the curtain is pulled up is smaller on the outside of the curtain and more on the inside.

FIG. 5 shows another embodiment of the present invention, in which cylindrical bodies 9, 9'... having a larger outer diameter than the winding drum 7a are fitted around the outer periphery of the winding drum 7a having the smallest diameter. By inserting the cord, a winding drum with a larger winding diameter for the lifting cord can be freely formed.

Furthermore, Fig. 6 shows a state in which the curtain is pulled up in an example in which three types of winding drums with different winding diameters are used. The curtain 3 to which the lower ends of the lifted and lowered cords 2a, 2b, 2c are connected
As shown in the figure, the hem part shows three stages of being pulled up.

[Effect of idea]

As mentioned above, the folding curtain according to the present invention does not have to operate a large number of lifting cords one by one, unlike the conventional method, by appropriately changing the winding diameter of the winding drum for each lifting cord. There is no need to adjust the height of the hem of the curtain by using a single operation code, and you can easily change the height of the hem of the curtain in stages. As for the operation section for the curtain, only one operation cord is exposed on the side of the curtain, so that it is possible to provide a fold-up curtain with an excellent design.
