Description

Apparatus for maintaining curtain crease}

The present invention relates to a curtain pleat maintenance device, and in particular, to a curtain pleat maintenance device in which pleats are formed at regular intervals and the formed pleats can be maintained even when flat pleated curtains are drawn.

In general, curtains cover windows for the purpose of blocking sunlight, protecting privacy, maintaining indoor temperature, etc. The top of the curtain is usually fixed at regular intervals to a plurality of rollers movably coupled to a rail installed on the ceiling adjacent to the window. As the roller moves, the curtain is drawn or lifted.

These curtains include pleated curtains (e.g., butterfly pleated curtains) in which certain wrinkles are always formed not only when the pleats are sewn and rolled up but also when draped, and flat pleated curtains in which wrinkles are formed when rolled up but the wrinkles are spread out when saggy. There are curtains, etc.

Pleated curtains have abundant, evenly formed wrinkles and do not straighten even when washed. However, because they require a lot of fabric, raw material costs and processing costs are high. On the other hand, flat pleated curtains reduce costs because they require less fabric than pleated curtains, but have the disadvantage that the wrinkles smooth out when hung and disappear when washed.

In order to make up for the shortcomings of these plain pleated curtains, shape memory curtains have been released recently. However, shape memory curtains are manufactured by shaping and steaming at high heat of about 120℃, so the production cost is high, which offsets the fabric saving effect, and varies from product to product. However, there are many products that wrinkle when washed.

The purpose of the present invention is to solve the above problems and to provide a curtain pleat maintenance device that can stably maintain the formed pleats while forming abundant and even pleats like a pleated curtain even when a flat pleated curtain is drawn.

The present invention, a curtain pleat maintenance device for achieving the above object, includes a rail installed on the ceiling; a plurality of rollers movably coupled to the rail and fixed to upper ends of the flat pleated curtain at regular intervals; It includes a cable member that connects adjacent rollers and allows the rollers to move only to the point where the wrinkles of the flat pleated curtain are formed at regular intervals when the flat pleated curtain is drawn.

In addition, the cable member includes a link formed to open and close at one point and coupled to a roller, a cable connecting one link coupled to one roller and another link coupled to another roller, and an adjacent roller. It can be formed to a length shorter than the width of the plain pleated curtain portion connected to.

Additionally, the cable may be formed in a curved shape or in a bent straight shape.

In addition, the roller includes a slide part located in a rail groove formed inside the rail, a curtain fixing part provided on the lower side spaced apart from the slide part and fixing the upper end of the flat pleated curtain, and a slide part while passing through the entrance of the rail groove. It connects both edges of each of the curtain fixing parts and the curtain fixing part, and may include two cable fixing parts in which connecting rings of different cable members are adjacently coupled to each other.

Additionally, the link may be coupled to the cable fixing portion so that the point where the cable is convex or bent toward the rear of the plain pleated curtain is located at the rearmost position.

According to the present invention, when a plurality of rollers fixed at regular intervals to the upper part of a plain pleated curtain move along the rail to draw the curtain, they move only to the point where the pleats of the curtain are formed at regular intervals by the cable member, so the pleated curtain As abundant and even wrinkles are formed, the formed wrinkles can be maintained stably.

In this way, for flat pleated curtains, which require less fabric and have lower processing costs than pleated curtains, the same effect as pleated curtains can be obtained simply by connecting adjacent rollers through cable members, making them highly economical and versatile, and anyone can easily install them. do.

The scope of the present invention is not limited to the embodiments described below, and various modifications may be made by those skilled in the art without departing from the technical gist of the present invention.

Hereinafter, the curtain pleat maintenance device of the present invention will be described in detail with reference to the attached FIGS. 1 to 9.

The curtain pleat maintenance device of the present invention includes a rail 100, a roller 200, and a cable member 300, as shown in FIGS. 1 to 3.

' 형태로 형성될 수 있다. 따라서, 롤러(200)는 레일(100)의 일단을 통해 끼워져 상단부가 레일홈의 내측에 위치되면서 상단부와 인접한 하측이 레일홈의 입구를 지나게끔 구비될 수 있다. The rail 100 can be installed on the indoor ceiling adjacent to the window, and is configured to move the roller 200 on which the upper end of the curtain is fixed. As an example, the rail 100 is formed on the inside along the longitudinal direction, as shown in FIGS. 2 and 3, where the upper end of the roller 200 can be positioned, and the rail groove communicates with the outside. Preferably, the entrance of the rail groove may be formed below the rail groove. In other words, the rail 100 has a longitudinal cross section of '

' It can be formed in the form. Accordingly, the roller 200 may be fitted through one end of the rail 100 so that the upper end is located inside the rail groove and the lower side adjacent to the upper end passes through the entrance of the rail groove.

A plurality of rollers 200 are movably coupled to the rail 100 and the upper end of the curtain is fixed to each, and the curtain in the present invention refers to a plain pleated curtain manufactured so that wrinkles are not formed during production. As shown in Figures 1 and 2, the upper end of the flat pleated curtain 10 may be fixed to the plurality of rollers 200 at regular intervals, and fixing pins are inserted into the upper end of the flat pleated curtain 10 at regular intervals. Higo fixing pins may be inserted into each roller 200.

This roller 200 may include a slide part 210, a curtain fixing part 220, and a cable fixing part 230, as shown in FIGS. 4 and 5, for example. Specifically, the slide part 210 is formed in the shape of a plate smaller than the rail groove and is located within the rail groove formed inside the rail 100 so that it can be moved along the rail groove. The curtain fixing part 220 is formed in a plate shape corresponding to the slide part 210 and may be provided parallel to the slide part 210 on the lower side spaced from the slide part 210, and has a curtain fixing protrusion facing downward. The upper end of the flat pleated curtain 10 can be fixed by inserting a fixing pin inserted into the upper end of the flat pleated curtain 10 into the protruding curtain fixing protrusion.

And, two cable fixing parts 230 are formed to connect both edges of the slide part 210 and the curtain fixing part 220 while passing through the entrance of the rail groove. That is, the two cable fixing parts 230 are provided to be spaced apart from each other, and a coupling space may be formed between them. Different cable members 300 are coupled to each of the two cable fixing parts 230.

The cable member 300 connects adjacent rollers 200 to a plurality of rollers 200 movable along the rail 100, as shown in FIGS. 1 and 2 . As an example, the cable member 300 is formed to open and close at one point as shown in FIGS. 4 to 8 and has a connecting ring 310 coupled to the roller 200 and a connecting ring 310 coupled to one roller 200. It may include a cable 320 connecting one link 310 and another link 310 coupled to the other roller 200.

Specifically, the link 310 is, as shown in FIG. 4, ' A hook part forming a hook shape, one end of which is connected to one end of the straight part of the hook part and extending toward the other end, which is the end of the curved part of the hook part, and the other end of which is separated from the other end of the hook part, and an elastic rotating part of the hook part. It may include an elasticity granting portion formed to provide elastic force to the elastic rotational portion at a point where one end and one end of the elastic rotational portion are connected.

For example, the elasticity granting portion may be composed of a groove recessed into the inside of the point where one end of the hook portion and one end of the elastic rotating portion are connected. This gives elastic force to the elastic rotating portion, and the other end of the elastic rotating portion After being pressed inward, it can be returned to face the other end of the hook. Therefore, the user presses the other end of the elastic rotating part inward to position the cable fixing part 230 inside the connecting ring 310 and releases the pressure on the other end of the elastic rotating part to secure the cable fixing part 230 to the inside. The connection ring 310 may be in a coupled state. That is, the connecting rings 310 of different cable members 300 may be adjacently coupled to each of the two cable fixing parts 230 constituting the roller 200.

As described above, the cable 320 is bent or folded to form a predetermined length to connect one link 310 coupled to one roller 200 and the other link 310 coupled to the other roller 200. This can be made of any available material. The cable 320 may be formed in a straight line, but is preferably formed in a curved or bent straight line so that it can be easily bent or folded. As an example, as shown in FIG. 6, it may be formed in a curved shape such as ')' so that it can be bent, and as another example, as shown in FIG. 7, it may be formed in a bent straight shape like '>'. It can be formed and configured to be foldable. This cable 320 is bent or folded so that when the gap between the rollers 200 to which the two connecting rings 310 connected thereto are narrowed, the gap between the two connecting rings 310 is narrowed together.

As another example, when the cable 320 is formed in a curved shape such as ')' and is configured to be bendable, it may be made of an elastic material to maintain this shape, and the elasticity may be weakened due to continuous bending. To prevent this, as shown in FIG. 8, an elastic reinforcement portion 330 may be added to the area where bending occurs.

The cable member 300 as described above is preferably formed to have a length shorter than the width of the portion of the flat pleated curtain 10 connected to the adjacent roller 200. That is, the length of the cable member 300 is greater than the distance between the curtains 10 to which one roller 200 coupled with one link 310 and the other roller 200 coupled with the other link 310 are respectively fixed. Because it is formed to be short, wrinkles may be formed in the curtain 10 even if the cable member 300 is stretched to its maximum length.

In addition, the connecting ring 310 may be coupled to the cable fixing part 230 so that the point where the cable 320 is convex or bent toward the rear of the plain pleated curtain 10 is located at the rearmost position. This is to ensure that the plurality of cable fixing parts 230 are all bent, folded, and unfolded on the same side, and that the cable member 300 is not exposed to the outside as much as possible when looking at the curtain 10 from the front.

As described above, in the present invention, as shown in FIG. 9, when a plurality of rollers 200 fixed at regular intervals to the upper part of the plain pleated curtain 10 move along the rail 100 to draw the curtain, the cable member Since (300) moves only to the point where the wrinkles of the curtain 10 are formed at regular intervals, abundant and even wrinkles like a wrinkled curtain are formed and the formed wrinkles can be maintained stably. With respect to the flat pleated curtain (10), which requires less fabric and has lower processing costs than the pleated curtain, the same effect as the pleated curtain can be obtained simply by connecting adjacent rollers through the cable member (300), making it highly economical and versatile. Anyone can install it easily.
