BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain apparatus capable of opening /

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain apparatus, and more particularly, to a curtain apparatus capable of opening / closing a curtain by vertically adjusting the upper and lower control lines and the upper and lower control lines.

Generally, windows are installed in buildings. The window has the advantage of allowing the sunlight to enter the room even when it is sealed from the outside. The window is installed with a hinged or sliding door so that air can be opened or closed. Although there are many kinds of window materials, it is common to use glass.

These windows include curtains, blinds, and vertical blinds to protect privacy or block the sun. The most common is the curtain. The curtain is installed so as to be able to open and close the upper end of the curtain on the inner upper side of the window. The curtains are typically folded sideways and folded back and forth to open the windows. There is also a so-called Roman shade, which is configured to open and close up and down.

Recently, a roll blind with a weight bar at the bottom has been widely used. The roll blinds are configured to adjust the height of the blinds to a desired height by arranging the rolls on the upper roll by winding or unwinding the blinds.

The so-called vertical blind means that a plurality of louvers are installed so as to be movable left and right along the upper rail, respectively, and installed so as to be rotatable at the same time, and installed so as to perform a sunshade function by moving left and right louvers.

In the case of a curtain, it is not a method of using a line, but a curtain, a roll blind, and a vertical blind. Roller blinds are configured so that rolls are rotated and pulled or unfolded by pulling the adjustment rope connected to the device installed on the roll, but this is often the case when the blind is slightly raised and the window is opened. In the case of blowing, when the wind pushes the blind, the blind is returned, and the weight stick at the bottom collides with the outer surface or the window frame, causing noise. In the case of a vertical blind, it is opened by moving all to one side. However, there is a problem that even if the user wants to open the window by slightly raising the upper part according to his / her choice, the user must move both to the left and right directions.

As a prior art document, Korean Utility Model Publication No. 1999-0034813 is known. This practical design is concerned with the carrier of the vertical blind, and the above-mentioned problems of the prior art are intrinsically incorporated. That is, even if only a part of the blind is to be raised, there is a problem that the whole should be completely pushed sideways.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a double curtain which is capable of controlling the opening and closing of curtains by adjusting two curved lines, Which can be opened, closed, opened, closed, and opened / closed.

In order to accomplish the above object, the present invention provides a railway vehicle comprising: a plurality of carriers each fixed at a predetermined interval on an upper end of a curtain; a rail assembled to allow the carriers to be transported; And a bobbin rotatably installed in the carrier. The other end of the wire is wound around the bobbin and the other end is fixed to the lower end of the curtain. And upper and lower connecting wires for rotating the rotating rods provided through the rotating holes of the bobbins.

Preferably, the carrier is provided with rollers at both ends and is slidably assembled to the rail.

Preferably, the carrier is provided with a spacer so that the maximum distance from the adjacent carrier is limited.

Preferably, the curtains are fixed in the vertical direction, and the upper and lower connecting wires are installed in the ring.

The above objects, features and advantages of the present invention will become more apparent from the following detailed description. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The curtain device according to the preferred embodiment of the present invention includes a plurality of carriers 20 fixed to the upper end of the curtain 1 at regular intervals and a rail 20, 10 installed at both ends of the rail 10 and pulleys 41 and 42 provided at both ends of the rail 10 so as to pass through the carriers 20 so that the carriers 20 are transported along the rails 10 And a bobbin 60 rotatably installed in the carrier 20. The bobbin 60 has one end wound and the other end fixed to the lower end of the curtain 1. The upper and lower connecting wires 40, And an upper feed wire 30 for rotating the rotary bar 70 installed through the rotation holes 60b of the bobbins 60.

The carrier 20 has rollers 13 at both ends thereof and is slidably assembled to the rail 10. The carrier (20) is provided with a spacer (100) so that the maximum distance from the adjacent carrier (20) is limited. The carrier 20 includes a main body having a seating groove 21 in which the bobbin 60 is rotatably assembled and a hole 22 through which the left and right conveying wire 40 passes, 1 is fixed to the upper end of the ring portion 23.

The carrier 20 is installed at a predetermined interval on the upper end of the curtain 1 as shown in FIG. The carrier (20) is slidably mounted on the rail (10) by a roller (13). Therefore, when the carrier 20 moves all the way to one side, the curtain 1 is folded along the left and right direction. The folded state in the left and right direction is shown in Fig. The carriers 20 are moved all the way to the left side, and the space between the carriers 20 is reduced. Therefore, the carriers 20 are naturally folded right and left of the curtain 1, This operation is accomplished by adjusting the left and right feed wires 40.

When the upper and lower feeding wires 30 are adjusted in the state as shown in FIG. 2, the curtains 1 are folded into the state shown in FIG. That is, the curtain 1 folded in the right and left is folded upward to be raised. 4, when the upper and lower connecting wires 50 are wound on the bobbin 60, the curtain 1 is folded up along the vertical direction. The upper and lower connecting wires 50 are fixed to the lower end of the curtain 1 at the lower end 51 and fixed at the other end to the bobbin 60. In particular, (52) are fixed, and the upper and lower connecting wires (50) are installed to penetrate the ring (52). The rings 52 are provided at regular intervals along the vertical direction from the lower end of the curtain 1. [ Since the rings 52 are provided, the curtain 1 can be folded up and down. If the lower and upper connecting wires 50 are fixed, the curtain 1 is wound to some extent and the middle of the curtain 1 falls down again.

The carrier 20 is well shown in Figure 5. One bobbin (60) is provided on each carrier (20). A through hole 22 is formed at one side of the carrier 20 so that the through hole 22 can penetrate both of the right and left feed wires 40. Finally, a ring 23 is formed at the lower end of the main body of the carrier 20 so that the upper ring 2 of the curtain 1 is fitted to the ring 23 and assembled. The upper ring 2 can be inserted or removed from the ring portion 23, so that operations such as replacement and addition can be performed very easily. Since the last carrier 20 is to be fixed to the rail 10, another fixing member is provided instead of the roller 13 so as to be assembled.

A hole 20a through which the upper and lower connecting wires 50 pass is formed in the lower portion of the main body of the carrier 20. [

The left and right feed wires 40 are fixed in an endless loop by pulleys 41 and 42 rotatably fixed inside the both ends and caps 11 and 12 of the rail 10. Therefore, the left and right feed wires 40 are able to infinitely rotate between the pulleys 41 and 42. And a part of the pulley 42 is partially lowered. The elongated portion is for the user to hold and adjust. The left and right feed wires 40 are installed through the through holes 22 of the respective carriers 20. Therefore, the carrier 20 can not be transported in a state where the left and right transport wires 40 are simply penetrated. The first carrier 20 on the left side may be fixed to one line of the left and right feed wires 40 penetrating through the two lines. Then, the carrier 20 is conveyed to the left and right according to the adjustment of the left and right feed wires 40. Although not shown in the figures, the carrier 20 is not fixed, but a fixing piece fixed to one line of wire is provided before and after the first wire. Then, since the fixed member moves the carrier to the left and right side, it has the same effect. The remaining carriers 20 are physically pushed to the right by the first carrier 20. Since the spacers 100 are provided between the adjacent carriers 20 to limit the maximum distance therebetween, when the carrier 20 is conveyed to the left side by a certain distance, As shown in Fig. In this manner, the carriers 20 are continuously transferred to return to the original state shown in Fig.

6 to 9, the rotary shaft 60a of the bobbin 60 is seated on the seating groove 21 of the main body. The rotary shaft 60a of the bobbin 60 is formed so as to protrude to both sides. The rotation hole 60b of the bobbin 60 is formed in a cross shape in its cross section, and a rotation bar 70 is inserted in the cross rotation hole 60b. Accordingly, the bobbin 60 is destined to rotate along with the rotation of the rotation bar 70. Instead of the cruciform rotation hole 60b, one or more grooves may be formed in the rotation hole 60b, and the rotation bar 70 may be provided with a projection that engages with the groove. Therefore, it is needless to say that the cross-section of the rotation hole 60b and the rotation bar 70 is formed in a cross shape as an example.

An upper end of the upper and lower connecting wires 50 is fixedly wound on the bobbin 60. Since the lower end of the upper and lower connecting wire 50 is fixed to the lower end of the curtain 1, the load of the curtain 1 is burdened by the upper and lower connecting wires 50. Therefore, when the curtain 1 is light, the bobbin 60 is not rotated by the load, but when the curtain 1 is wound up, when the curtain 1 is heavy, the bobbin 60 is rotated by the load, ) May be lowered. This is solved by the stopper 73 of the prior art. The known stopper 73 is used to prevent the bobbin 60 from being rotated by a reasonable force so that the position of the curtain 1 is maintained even if the curtain 1 is heavy.

5, an end of the rotation rod 70 is fixed to the bushing 71 and is rotatably fixed. The other end of the rotation rod 70 is connected to the upper and lower transfer wires 30 via a bushing 72 and a stopper 73 And rotates the rotary bar 70 by rotating the upper rotary bar 30. All the bobbins 60 are simultaneously rotated in the same direction as the rotary bar 70 is rotated and the curtain 1 is wound up when the upper and lower connecting wires 50 are wound on the bobbin 60. Conversely, when the upper and lower connecting wires 50 are rotated to unfold the bobbin 60, the curtain 1 is loosened from the upper portion.

The operation will be described based on the description of the components as described above.

1, if one line is pulled out of the lines of the left and right feed wires 40, the left and right feed wires 40 are provided so as to form an infinite loop between the pulleys 41 and 43, The line is pushed out. The left first carrier 20 is moved to the right along with the movement of the left and right feed wires 40, so that the curtain 1 also starts to be folded from the left side. When the first carrier 20 contacts the second carrier 20, the second carrier 20 also moves to the left with the first carrier 20. These operations are successively performed to transfer the carriers 20 to the right end. Since the last carrier 20, that is, the rightmost carrier 20 is structured to be fitted and fixed to the rail 10 instead of the roller 13, even if the adjacent carrier 20 is closely contacted, it does not move. Therefore, even if the left and right feed wires 40 are pulled further, they do not move. This state is shown in Fig.

Conversely, when the above-described opposite line is pulled in the state shown in FIG. 2, the first left carrier 20 starts to be conveyed to the left along the line. When the curtain 1 is moved to a certain extent, the curtain 1 is fully opened and the adjacent second carrier 20 starts to be conveyed to the left. At this time, since the spacer 100 is provided between the two adjacent carriers 20, even if the curtain 1 is not completely opened, the second carrier 20 starts to move naturally when the spacer 100 reaches the maximum clearance. The spacer 100 employs one used in a known vertical blind. Of course, even if there is no spacer 100, it is natural that the second carrier 20 is transported along with the curtain 1 fully opened. However, since the maximum clearance between the adjacent carriers 20 can be adjusted by providing the spacer 100, the carriers 20 can be moved even if the curtain 1 is not completely opened, and the shape of the curtain 1 can be adjusted There are differences in points.

The folding operation of the curtain 1 in the state as shown in Fig. 1 or 2 is possible by adjusting the upper feeding wire 30. Of course, it is possible to fold up or down regardless of whether the curtain (1) is folded left or right or unfolded. When the upper rotary wire 30 is adjusted, the rotary bar 70 connected thereto is rotated, and at the same time, the bobbins 60 having the rotary bar 70 inserted therein are also rotated together. When the upper and lower connecting wires 50 are rotated in the direction of winding the upper and lower connecting wires 50 to the bobbin 60, the upper and lower connecting wires 50 are wound on the bobbin 60 and the lower ends of the curtains 1 are raised, It is folded up and folded upward to be in a state as shown in Fig. Conversely, when the upper rotary wire 30 is rotated, the upper and lower connecting wires 50 wound on the bobbin 60 are disengaged and the lower end of the curtain 1 is lowered, so that the curtain 1 is unfolded in the vertical direction. If only the lower end of the curtain 1 is fixed to the upper and lower connecting wires 50, the curtain 1 will be folded at first and folded in half as the curtain 1 is passed over. However, in the present invention, since the loop 52 is fixed at a certain height of the curtain 1 and the upper and lower connecting wires 50 are passed through the loop 52, the curtain 1 is folded in a predetermined shape, So that the overall appearance is beautifully folded. Of course, a similar effect can be obtained even if the collar 52 is not used and fixed at that position by sewing.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
