Description

Roman Shade Blind

The present invention relates to a Roman shade curtain that can revive the atmosphere of the curtain and the interior of the house by unfolding or folding the curtain in steps like a lace. In particular, the structure of the driving device for unfolding and folding the curtain is improved to allow the curtain to be left or right. It is about Roman shade curtains that can be unfolded or folded in a balanced manner.

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

There are several types of these curtains depending on their shape, for example, regular curtains that unfold and fold to the left and right, vertical blinds made of multiple pieces that adjust the inclination angle, roll screen curtains in which the curtains are wound and unwound on a rotating roll, and length-adjustable curtains. There are Roman shade curtains that fold or unfold in steps by the winding action of the string.

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

These Roman shade curtains basically have the feature of forming a plurality of wrinkles as the curtain part is folded and raised, giving it a beautiful appearance when the Roman shade is fully raised.

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

The Roman shade type blind consists of fabric (3), hooks (4), and strings (5).

The fabric (3) is woven by interlacing the warp (1) and weft (2), and some of the weft (2) is not interlaced with the warp (1), forming a ring (4).

The warp yarns (1) are interlaced as they pass between the weft yarns (2), and then interlaced except for some of the weft yarns (2), so that the weft yarns (2) in the parts where the warp yarns (1) do not pass are gathered to form a ring (4). .

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

However, when the conventional Roman shade type blind opens or folds the curtain by manipulating one side of the string, the unwinding string often becomes tangled or twisted as it is wound around the drum of the driving device, which causes one side of the curtain to break. Not only does it have the disadvantage of poor curtain unfolding and folding operability, such as unfolding or folding crookedly, but it also has the disadvantage of deteriorating the appearance and causing malfunctions as one side of the curtain is tilted.

Accordingly, the present invention was conceived with this in mind, and the driving device that provides power for folding and unfolding the curtain is equipped with a drum with a guide function that normally winds or unwinds the operating line, and has a predetermined width. By implementing a new type of curtain driving device using a string with a string, it is possible to improve the unfolding and unfolding operability of the curtain, such as allowing both the left and right sides of the curtain to be unfolded or folded in a balanced and smooth manner, while also improving the appearance of the curtain. The purpose is to provide Roman shade curtains that can be ordered.

In order to achieve the above object, the Roman shade curtain provided by the present invention has the following characteristics.

The Roman shade curtain includes a driving device that winds or unwinds the operating line for folding and unfolding the curtain, and an operating line for manipulating the driving device, and is arranged at regular intervals along the vertical and longitudinal directions of the curtain, as well as in the left and right width directions of the curtain. A curtain that can be folded and unfolded up and down, having a plurality of tubular rod fittings formed horizontally in parallel and at least one string fitting formed on the rear of the curtain, and inserting and installing into each rod fitting of the curtain. The rod, which has an upper end fixed on the driving device side, extends downward while passing through the string insertion part of the curtain, and the lower end is fixed to the lower side of the curtain, and is wound or unwound on the driving device side to pull the curtain up or down. The main body consists of a structure that includes an operating line.

In particular, the driving device of the Roman shade curtain includes a case, a shaft installed inside the case in a rotatable structure while being supported at both ends, a gear installed on one end of the shaft and connected to an operating line, and installed on the shaft. It is used to wind or unwind the operating line, and may consist of a pair of drums that have a groove in the middle of the width of the outer circumferential surface to prevent the operating line from moving left or right and to guide the operating line to be wound or unwound along a vertical line.

Here, the operating line is made of a strip-shaped string with a certain width, and the groove of the drum is made of a groove having a width corresponding to the width of the operating string, so that when the operating string is wound and unwound, the operating string is aligned in the groove. As they overlap and align, they can be wound or unwound.

In addition, the rod insertion part of the curtain can be formed as an integrated curtain through double weaving when weaving the curtain.

This Roman shade curtain may further include at least one tube or glass bead that is installed by being inserted into the operating line in the section between rods at the rear of the curtain and naturally induces the stepwise folding and unfolding form of the curtain.

In a preferred embodiment, the rod insertion portions of the curtain may be arranged at intervals where the distance between them becomes relatively wider from the upper end of the curtain to the lower end of the curtain.

The Roman shade curtain provided by the present invention has the following effects.

1) Since both the left and right sides of the curtain can be unfolded or folded in a balanced and smooth manner, it is possible to improve the unfolding and unfolding operability of the curtain and at the same time improve the appearance of the curtain.

2) By improving the structure of the curtain driving device and simplifying the overall structure of the Roman shade, curtains can be manufactured simply and easily and production costs can be reduced.

3) As the strings, rods, and hooks for operating the curtain are placed on the back of the curtain, these things are not exposed at all on the front of the curtain, which has the effect of improving the appearance of the curtain.

4) When forming the rod insertion part for inserting the rod into the curtain fabric, by applying a method of forming the rod insertion part by weaving it integrally during the weaving of the curtain, the manufacturability of the curtain including the rod insertion part can be improved and at the same time, the front of the curtain can be improved. This has the effect of ensuring the quality of the product, such as not showing signs of irregularity such as stitching.

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

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

As shown in Figures 1 to 4, the Roman shade curtain includes a driving device 12 as a means of providing power for folding and unfolding the curtain 10.

The driving device 12 is a winding device that winds or unwinds the operating line 11 when folding or unfolding the curtain 10, and can be installed horizontally at the upper end of a window, etc.

This driving device 12 uses a combination of the case 12, the shaft 18, the gear 19, and the drum 21 to fold or unfold the curtain 10 by winding or unwinding the operating line 11. can do.

The case 12 is in the form of a long rectangular cylinder with at least one side open, and is fixedly installed at the upper end of a window, etc.

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 horizontally and parallel to the inside of the case 12 and is supported on both walls of the case 12 using both ends. The shaft 18 installed in this way is centered around its own axis. This allows it to rotate freely.

The gear 19 is installed on one end of the shaft 18 and can rotate together with the shaft 18.

A ring-shaped operating line 13 is attached to this gear 19, and when the user pulls one side of the operating line 13 down, the gear 19 rotates in the forward direction and at the same time, the axis 18 ) Also, as it rotates in the forward direction, the operating line 11 can be wound around the drum 21, and when the user pulls the other side of the operating line 13 down, the gear 19 rotates in the reverse direction and at the same time, the axis ( 18) Also, by rotating in the reverse direction, the operating line (11) can be released from the drum (21).

The drum 21 is a cylindrical drum that serves to wind or unwind the operating line 11. It has a relatively large diameter compared to the shaft 18 and is coaxially coupled to the shaft 18. 18) and is rotatably installed.

Two such drums 21 may be provided, and each drum 21 is arranged at a distance from left to right on the axis 18, so that two rows of operating lines 11 can be wound or released at the same time.

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

At this time, the groove 20 is made of a groove with a width corresponding to the width of the operating line 11. Accordingly, when the operating line 11 is wound or released within the groove 20 of the drum 21, Since the operating line 11 is regulated by both walls of the groove 20, the operating line 11 can be wound or unwound while overlapping in a row within the groove 20, such as in the groove 20 of the drum 21. ) can be wound or unwound in a neatly aligned state without tangling or climbing on each other as before.

In this way, the operating lines (11) are wound or released while being aligned in a consistent manner as if overlapping in a row within the grooves (20) of the drum (21), so the two operating lines (11) on both sides can be pulled up or down in a balanced manner. In the end, the curtain 10, which is folded or unfolded by these two operating lines 11, can be folded or unfolded in balance on the left and right without being tilted or crooked to either side.

In addition, the Roman shade curtain includes a curtain 10 made of a cloth material or a synthetic resin material, and the upper part of the curtain 10 can be supported by a structure attached to the inner lower part of the case 17. The curtain 10 can be maintained in an upright state without flaccid due to the weight of the rod 16, which serves as a mass.

At least one string fitting part 15 is formed on the rear of the curtain 10, for example, two cord fitting parts 15 arranged in the left and right width directions of the curtain.

Here, two row fitting portions 15 can be formed on both sides of the left and right width directions at each position where each rod fitting portion 14 is formed.

In addition, a plurality of tubular rod fitting parts 14 are formed in the curtain 10, and each rod fitting part 14 formed in this way is arranged side by side along the left and right width directions of the curtain and at the same time in the vertical direction of the curtain. It can be placed at regular intervals along the line.

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

For example, when weaving the curtain 10, the curtain body is woven in 1 layer, and then 2 layers are woven at the position where the rod insertion portion 14 is formed to create a space (rod insertion portion) into which the rod is inserted, and then again in 1 layer. 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 insertion portion 14 is formed below, to create a space (rod insertion portion) where the rod is inserted, the curtain 10 is made. It is possible to form a plurality of rod fitting portions 14 in an integrated form through weaving.

In this way, by forming the rod insertion portion 14 into a curtain-integrated form through weaving, productivity related to curtain production can be improved, which ultimately has the advantage of enabling mass production of curtains.

In this way, each rod 16 can be inserted into each rod insertion portion 14 formed on the curtain 10, and the rod 16 at this time is made of a metal material or plastic material with a predetermined weight. It can be made of square bars or round bars.

In addition, the plurality of rod fitting parts 14 woven in the curtain 10 can be arranged at intervals where the distance between them becomes relatively wider from the upper end of the curtain to the lower end of the curtain.

For example, the gap between the rod insertion portion 14 disposed at the uppermost end of the curtain 10 and the rod insertion portion 14 disposed immediately below is relatively narrow, and as it continues downward, it becomes smaller. The gap between the rod fitting parts 14 gradually widens, and the gap between the rod fitting part 14 disposed at the bottom of the curtain 10 and the rod fitting part 14 disposed immediately above becomes relatively the smallest. It becomes wide.

Ultimately, the further downward the curtain 10 goes, the wider the spacing between the rod inserts 14 becomes.

In this way, the rod fitting parts (as well as the rod fitting parts attached to the curtain), which are woven together and formed as one during the weaving of the curtain, are arranged at intervals where the distance between them becomes relatively wider from the upper part of the curtain to the lower part of the curtain. By varying the spacing, the aesthetic characteristics of the Roman shade can be further improved, such as maintaining the overall folded shape when the curtain is folded and raised (when the Roman shade is folded and raised).

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

The operating line 11 is made of a strip-shaped string having a predetermined width, and the upper end of the operating line 11 is a groove (21) of the drum 21 installed on the axis 18 of the driving device 12. 20), and at the same time, the lower end extends vertically while sequentially passing through each string fitting portion 15 formed on the rear of the curtain 10 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 line 11 is wound or unwound in the groove 20 of the drum 21, and this operating line 11 ) The lower end of the curtain 10 is pulled up or down by the winding and unwinding operation, so that the folding and unfolding operation of the curtain 10 can be performed.

Here, the string insertion portion 15 formed at the rear of the curtain 10 is made in the form of a hole with a structure that penetrates up and down. For example, after applying a strip-shaped cloth to the rear of the curtain, both sides are attached to the curtain side. By sewing and blocking, it is possible to create a space that naturally passes up and down in between, and the operating string (11) can be inserted into the space created in this way, that is, the string insertion portion (15).

In particular, the operating line 11 is made of a strip-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 line 11. Therefore, when the operating line 11 is wound and unwound, the operating line 11 is aligned and overlapped in a row within the groove 20, allowing it to be wound or unwinded.

Figures 5 and 6 are perspective views showing tubes and glass beads used for stepwise folding and unfolding of a Roman shade curtain according to an embodiment of the present invention.

As shown in FIGS. 5 and 6, the rear portion of the curtain 10 is provided with a tube 22 or a glass bead 23 that is inserted into the operating line 11 in the section between the rods 16 and the rods 16. is installed, and the tube 22 or glass bead 23 installed in this way regulates the gap between the rods 16 and the rods 16 when the curtain 10 is folded, so that the curtain 10 is of the tube 22. It serves to regulate the gap so that it is not narrowed further than the gap corresponding to the length and the gap corresponding to the length into which the glass bead 23 is inserted.

Here, the tube 22 may be composed of one or two tubes having a predetermined length, and the glass beads 23 may also be composed of an appropriate number to maintain the predetermined length.

Accordingly, when the curtain 10 is folded, the curtain 10 and each rod 16 rise together. At this time, the gap between the rods 16 gradually narrows and the tube 22 or the 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 its folded state.

At this time, by appropriately adjusting the length of the tube 22 or the number of glass beads 23, it is possible to adjust the degree of folding of the stepped shape of the curtain 10.

Therefore, looking at the usage status of the Roman shade curtain constructed in this way, it is as follows.

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

As shown in Figure 7, here the curtain is unfolded downward.

To this end, when the user pulls one side of the operating line 13 downward, the operating line 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. It can be expanded downward using .

Here, the curtains 10 are unfolded sequentially from the bottom side, forming a cascade like lace, thereby enhancing the curtain atmosphere and the interior of the house.

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

As shown in Figure 8, the curtain is shown folded upward.

To this end, when the user pulls the other side of the operating line 13 downward, the operating line 11 is wound around the drum 21 of the driving device 12, and at the same time, from the lower side of the curtain 10. As it is pulled upward, it folds in a stepwise fashion and rises upward, and eventually the curtain 10 is completely folded upward and remains folded in a stepwise manner like a lace.

At this time, the operating line 11 is wound in a vertical line around the groove 20 of the drum 21, so that both left and right sides of the curtain 10 can be raised and folded in a balanced manner.

In addition, the tube 22 or the glass bead 23 at the rear of the curtain 10 can properly regulate the gap between each rod 16 pulled upward together with the curtain 10, that is, the rod 16 and Since the gap between the rods 16 is no longer narrowed by the tube 22 or the glass bead 23, the stepwise folding degree of the curtain 10 when the curtain 10 is fully folded, that is, the curtain 10 ) can be adjusted appropriately.

As such, in the present invention, a driving device that provides power for folding and unfolding the curtain is equipped with a drum that induces normal winding and unwinding of the operating line, and in addition, a new band-shaped string with a predetermined width is applied. By providing a curtain driving device, the unfolding and unfolding operability of the curtain can be improved, such as allowing both the left and right sides of the curtain to be unfolded or folded in a balanced and smooth manner.
