Description

Roman Shade Blind

The present invention relates to a Roman shade curtain that can save the curtain atmosphere and the interior of the house by unfolding or folding the curtain in steps like a lace. It is about a Roman shade curtain that can be unfolded or folded in a balanced way.

In general, curtains are used to block light or objects in everyday life, such as blocking sunlight or covering a stage.

There are several types of curtains depending on the shape, for example, a normal curtain that unfolds and folds left and right, a vertical blind made of a plurality of pieces to adjust the inclination angle, a roll screen curtain that is wound and unwound on a rotating roll, and length adjustment There are Roman shade curtains that are folded or unfolded stepwise by the winding motion of the string.

Recently, not only the function of curtains but also aesthetic elements are considered important, and Roman shade curtains with a beautiful folding shape are gaining popularity.

These Roman shade curtains basically form a plurality of folds as the curtain part is folded and raised, so that the appearance is beautiful when the Roman shade is completely raised.

As an example, Korean Patent Publication No. 10-1163864 discloses a Roman shade type blind.

The Roman shade type blind is composed of a fabric (3), a ring (4) and a string (5).

The fabric 3 is woven by intersecting the warp yarn 1 and the weft yarn 2, and some of the weft yarns 2 do not intersect the warp yarn 1 and the loop 4 is formed.

The warp (1) intersects while passing between the weft yarns (2), and then intersects except for some weft yarns (2), so that the weft yarns (2) in the portion where the warp yarns (1) do not pass are gathered to form a ring (4) .

Accordingly, the Roman shade type blind is completed by the string 5 passing through the ring 4 formed in this way.

However, in the conventional Roman shade type blind, when unfolding or folding a curtain by manipulating one of the lines, the lines that are unwound along with being wound on the drum of the driving device are often tangled or twisted. There is a disadvantage in that the curtain unfolding and folding operability is deteriorated, such as being crookedly unfolded or folded, and the appearance deteriorates as one side of the curtain is inclined, as well as causing a malfunction.

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

1 to 3 are a perspective view and a cross-sectional view illustrating a Roman shade curtain according to an embodiment of the present invention, and FIG. 4 is a perspective view and a cross-sectional view illustrating a driving device for a Roman shade curtain according to an embodiment of the present invention.

1 to 4 , the romantic shade curtain includes a driving device 12 as a means for providing power for folding and unfolding of the curtain 10 .

The driving device 12 is a winding device that winds or unwinds the operating string 11 when the curtain 10 is folded or unfolded, and can be installed laterally at the upper end of a window or the like to be used.

This driving device 12 winds or unwinds the operating string 11 using a combination of the case 12, the shaft 18, the gear 19, and the drum 21 so that the curtain 10 is folded or unfolded. can do.

The case 12 is in the form of an elongated rectangular cylinder having at least one open, and is fixedly installed at an upper end of a window or the like.

Inside the lower end of the case 12, the upper end of the curtain 10 can be supported while being fixed in parallel.

The shaft 18 is installed in a structure supported on both wall surfaces of the case 12 using both ends while being horizontally arranged in parallel inside the case 12, and the shaft 18 installed in this way is centered on its own axis. so that it can rotate freely.

The gear 19 is installed at one end of the shaft 18 so that it can rotate together with the shaft 18 .

An operation line 13 in the form of a ring is hung on the gear 19, and accordingly, when the user pulls one side of the operation line 13 down, the gear 19 rotates in the forward direction and the shaft 18 ) Also, the operating string 11 can be wound around the drum 21 while rotating in the forward direction, and when the user pulls down the other side of the operating string 13, the gear 19 rotates in the reverse direction and at the same time the shaft ( 18) Also, while rotating in the reverse direction, the operating string 11 can be released from the drum 21 .

The drum 21 is a cylindrical drum that plays a role of winding or unwinding the operating string 11, has a relatively large diameter compared to the shaft 18, and is coupled to the shaft 18 in a coaxial structure to form a shaft ( 18) and is rotatably installed.

Two of these drums 21 may be provided, and each drum 21 is arranged with a gap left and right on the shaft 18 to simultaneously wind or unwind the two working strings 11 .

In particular, a groove 20 is formed on the outer peripheral surface of the drum 21 to prevent the left and right separation of the operating string 11 and to guide the operating string 11 to be wound or unwound along a vertical line in the middle of the drum width.

At this time, the groove 20 is made of a groove having a width corresponding to the width of the operating string 11, and accordingly, when the operating string 11 is wound or unwound in the groove 20 of the drum 21, Since the operating string 11 is regulated by both walls of the groove 20 , the operating string 11 can be wound or unwound while overlapping in a line within the groove 20 , such as the groove 20 of the drum 21 . ), which is wound or unwound in the operating line 11, can be wound or unwound in an aligned state without getting tangled or riding on each other as in the past.

In this way, since the operating strings 11 are wound or unwound while being uniformly aligned as if they are overlapped in a line within the groove 20 of the drum 21, both operating strings 11 can be pulled up or down in a balanced manner. In the end, the curtain 10 folded or unfolded by the two operating strings 11 can be folded or unfolded in a left-right balance without being inclined or twisted to either side.

In addition, the Roman shade curtain includes a curtain 10 made of a cloth material or synthetic resin material, and the upper end of the curtain 10 can be supported in a structure attached to the inner lower end of the case 17 , at this time of the curtain 10 can be maintained in a straight state without swaying due to the weight of the rod 16 serving as a mass.

On the rear surface of the curtain 10, at least one line fitting portion 15, for example, two line fitting portions 15 disposed in the left and right width directions of the curtain are formed.

Here, the string fitting portion 15 can be formed in two places on both sides of the left and right width direction at each position where each rod fitting portion 14 is formed.

In addition, a plurality of tubular rod fitting portions 14 are formed in the curtain 10, and each rod fitting portion 14 thus formed is arranged in parallel along the left and right width directions of the curtain and at the same time in the vertical direction of the curtain. can be arranged at regular intervals along the

In particular, as a method of forming the rod fitting portion 14, the rod fitting portion 14 can be integrally formed through a double weaving method during curtain weaving.

For example, while weaving the curtain body in one layer when weaving the curtain 10, weaving the curtain body in two layers at the position where the rod fitting part 14 is formed creates a space (rod fitting part) in which the rod is inserted, and again 1 Curtain 10 by repeating the above process, such as weaving the curtain body in layers and then weaving it in two layers at the position where the rod fitting part 14 below it is formed to create a space (rod fitting part) in which the rod is inserted. It is possible to form a plurality of rod fitting portions 14 integrally through weaving on the top.

As described above, by forming the rod fitting part 14 as a curtain unit through weaving, productivity related to curtain production can be improved, and consequently, there is an advantage that mass production of curtains is possible.

Each rod 16 can be fitted into each rod fitting portion 14 formed on the curtain 10 in this way, and the rod 16 at this time is made of metal or plastic material having a predetermined weight. It can be made of a square bar or a round bar.

In addition, the plurality of rod fittings 14 woven on the curtain 10 can be arranged at intervals in which the distance between each other becomes relatively wide from the upper end of the curtain to the lower end of the curtain.

For example, the interval between the rod fitting portion 14 disposed at the uppermost end of the curtain 10 and the rod fitting portion 14 disposed immediately below the curtain 10 is relatively narrowest, and as it continues downward, The interval between the rod fitting portions 14 gradually widens, and the interval between the rod fitting portion 14 disposed at the lowermost end of the curtain 10 and the rod fitting portion 14 disposed immediately above the curtain 10 is relatively the most become wide

As a result, as it goes down the curtain 10, the distance between the rod fitting portions 14 becomes wider.

In this way, when the curtain is weaved, the rod fitting parts (like the rod fitting part attached to the curtain), which are woven together and formed integrally, are arranged at intervals in which the distance between each other becomes relatively wide from the upper part of the curtain to the lower part of the curtain. By varying the spacing, when the curtain is folded up (when the Roman shade is folded up), the overall folded shape can be kept constant, and the aesthetic characteristics of the Roman shade can be further improved.

In addition, the Roman shade curtain includes an operating string 11 as a means for substantially folding and unfolding the curtain 10 while being raised or lowered by the driving device 12 .

The working line 11 is made of a band-shaped string having a predetermined width, and the upper end of the working line 11 is a groove ( 20), the lower end is vertically extended while passing through each of the line fittings 15 formed on the rear surface of the curtain 10 in turn from top to bottom, and is fixed to the lower end of the curtain 10.

Accordingly, when the shaft 18 of the driving device 12 and the drum 21 rotate, the operating string 11 is wound or unwound in the groove 20 of the drum 21, and the operating string 11 ), the lower end of the curtain 10 is pulled upward or lowered downward by the winding and unwinding operation, so that folding and unfolding operations of the curtain 10 can be made.

Here, the line fitting portion 15 formed on the rear portion of the curtain 10 is made in the form of a hole having a structure penetrating up and down. By sealing it by sewing, it can be made in such a way that a space that naturally penetrates up and down is created between them, and the operating string 11 can be inserted into the space created in this way, that is, the string fitting part 15 .

In particular, the working string 11 is made of a band-shaped string having a certain width, and correspondingly, the groove 20 of the drum 21 is a groove having a width corresponding to the width of the operating string 11 . Accordingly, when the operation string 11 is wound and unwound, the operation string 11 is overlapped in a line in the groove 20 and aligned while being wound or unwound.

5 and 6 are perspective views illustrating a tube and a glass bead adopted for stepwise folding and unfolding of a Roman shade curtain according to an embodiment of the present invention.

5 and 6, on the rear portion of the curtain 10, the tube 22 or glass bead 23 having a structure inserted into the operation line 11 in the section between the rod 16 and the rod 16. is installed, and the tube 22 or glass bead 23 installed in this way regulates the distance between the rod 16 and the rod 16 when the curtain 10 is folded, while the curtain 10 is the tube 22. It plays a role of regulating not to be further narrowed than the interval corresponding to the length and the interval corresponding to the length in which the glass bead 23 is inserted.

Here, the tube 22 may be formed of one or two pieces having a predetermined length, and the glass beads 23 may also be formed in an appropriate number maintaining a predetermined length.

Accordingly, when the curtain 10 is folded, the curtain 10 and each rod 16 are raised together. At this time, the distance between the rods 16 is gradually narrowed and then the tube 22 or glass bead 23 ), the gap between the ball 16 and the rod 16 is fixed, and eventually the curtain 10 forms a stepped shape in this state and can maintain the folded state.

At this time, if the length of the tube 22 or the number of glass beads 23 is appropriately adjusted, the degree of folding of the curtain 10 in the stepwise form can be adjusted.

Accordingly, the usage state of the Roman shade curtain configured as described above is as follows.

7 and 8 are perspective views illustrating a use state of a Roman shade curtain according to an embodiment of the present invention.

As shown in FIG. 7 , a state in which the curtain is unfolded is shown here.

To this end, when the user pulls down either side of the operating string 13, the operating string 11 wound around the drum 21 of the driving device 12 is released, and at the same time, the curtain 10 loses its own weight. can be used to unfold downwards.

Here, the curtain 10 is unfolded sequentially from the lower side, and is unfolded in a stepped form like a lace, thus saving the curtain atmosphere and the interior of the house.

At this time, since the working string 11 is released from the groove 20 of the drum 21 in a vertical straight line, both left and right sides of the curtain 10 can be spread out in a balanced manner.

As shown in FIG. 8 , a state in which the curtain is folded upward is shown here.

To this end, when the user pulls down the other side of the operating string 13, the operating string 11 is wound around the drum 21 of the driving device 12, and at the same time, from the lower end of the curtain 10 As it is pulled upward, it is folded one after another in a stepwise fashion and comes up, and eventually, the curtain 10 remains in a state folded in a stepwise fashion like a lace in a state in which it is completely folded upward.

At this time, since the operation string 11 is wound in a straight line perpendicular to the groove 20 of the drum 21, both sides of the curtain 10 can be folded while rising in a balanced way.

And, since the tube 22 or the glass bead 23 on the rear side of the curtain 10 can appropriately regulate the distance between each rod 16 pulled upward together with the curtain 10, that is, the rod 16 and the Since the gap between the rods 16 is no longer narrowed by the tube 22 or the glass bead 23, the degree to which the curtain 10 is folded in steps in the fully folded state, that is, the curtain 10 ) can be appropriately adjusted.

As described above, in the present invention, a drum inducing normal winding and unwinding of the operating string is provided in a driving device that provides power for folding and unfolding operations of the curtain, and a new belt-shaped string having a predetermined width is applied thereto. By providing the curtain driving device, it is possible to improve the opening and unfolding operability of the curtain, such as allowing both left and right sides of the curtain to be spread or folded in a balanced and smooth manner.
