[Technical field to which the invention belongs]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cord fastening device for Roman shade, and more particularly to a cord fastening device used for fastening a lifting cord to a shade fabric body of Roman shade.

[0002]

[Prior art]

 As is well known, the Roman shade is configured so that the shade cloth can be folded up in an orderly manner from the bottom of the shade cloth by raising an elevating cord fixed to the bottom of the shade cloth. Recently, a synthetic resin cord fastening tool has been used to fasten the lifting cord to the lower portion of the shade cloth.

That is, a tape having a loop portion is sewn on the lower portion of the shade cloth body, and a cord fastening device made of a synthetic resin is attached to the loop portion so that the hook portion hooks the cord fastening device. By winding the end of the lifting cord around the hooking protrusion of the tool, the lifting cord is fastened to the shade fabric body to facilitate the production of the Roman shade.

However, in the conventional cord fastening device, since the hook portion thereof is configured only in consideration of preventing the cord from slipping out of the loop, it is not necessary to attach the cord fastening device when actually manufacturing the Roman shade. It took time and effort.

[0005]

[Problems to be solved by the device]

 The present invention has been made in view of the above drawbacks of the conventional cord fastening device, and provides a cord fastening device that can be easily attached to a shade cloth body. Is a technical issue.

[0006]

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a hook portion 1 to be hooked on a loop L provided at a lower portion of a shade cloth body S of a Roman shade R, and the Roman shade. A cord fastening device comprising a trunk portion 2 provided with a latching projection 21 on which a lifting cord C for R is to be wound and wound, wherein the hook tip 11 of the hook portion 1 is reduced in diameter toward the tip. At the same time, a technical means is adopted in which a spherical bulge 12 is formed at the most distal end of the hook tip 11.

Further, in order to solve the above-mentioned problems, the present invention provides a virtual swelling portion 12 formed on the hook tip 11 in front of the body portion 2 in addition to the above-mentioned means as necessary. The technical means of projecting from the plane A in the direction opposite to the hooking protrusion 21 is adopted.

[0008]

[Embodiment of the invention]

 Hereinafter, the present invention will be described in detail based on an embodiment shown in the accompanying drawings. 1 is an overall perspective view of the back surface of the Roman shade to which the cord fastening device of this embodiment is applied, FIG. 2 is an overall side view of the cord fastening device of this embodiment, and FIG. 3 is the same. Fig. 4 is an overall front view, Fig. 4 is a perspective view of a main part showing a state of an attachment work of the cord fastening device to a shade cloth, and Fig. 5 is a perspective view of a main part showing a use state of the cord fastening device.

In FIG. 1, a code P indicates the cord fastener of the present embodiment. The cord fastener P of the present embodiment is attached to a total of three loops L, L, L provided on the bottom cloth tape T sewn to the shade cloth body S of the Roman shade R, respectively, and The ends of the three lifting cords C, C, C are wound around the cord fastening device P.

In FIG. 1, a symbol W indicates a synthetic resin ring member attached to the loop L of another cloth tape T, and the lifting cord C is passed through the ring member W. Has been done. Further, what is designated by the reference sign B is an operation code for operating the raising and lowering of the Roman shade R, and the operation code B drives the hoisting mechanism M to simultaneously hoist the hoisting and lowering codes C, C, C. As a result, the shade cloth body S is regularly folded upward from the lower part thereof.

As shown in FIGS. 2 and 3, the cord fastening device P of the present embodiment should wind and hook the hook portion 1 to be hooked on the loop L of the shade cloth S and the lifting cord C. It is composed of a body 2.

A flange portion 23 is formed so as to be carried out at a right angle from the upper end portion of the body portion 2, and a through hole 22 is formed at the root portion of the flange portion 23. Further, in the middle of the body portion 2, there is formed a bollard-shaped hooking protrusion 21 having an enlarged head portion. By winding the end of the elevating cord C passed through the through hole 22 of the collar portion 23 around the hooking protrusion 21, the elevating cord C is hooked on the cord stopper P of this embodiment ( (See FIG. 5).

On the other hand, in the hook portion 1 of the cord fastening device P, the hook tip 11 is reduced in diameter toward the tip, and a spherical bulging portion 12 is formed at the most distal end portion of the hook tip 11. . The hook portion 1 is configured so that the spherical bulging portion 12 projects in the direction opposite to the hooking protrusion 21 with respect to an imaginary plane A (see FIG. 2) which is based on the front surface of the body portion 2. Further, inside the hook of the hook portion 1, two barbs 13 and 13 facing each other are formed.

As described above, in the cord fastening device P of the present embodiment, since the hook tip 11 of the hook portion 1 has a smaller diameter, the hook tip 11 is more easily elastically deformed than other portions. As shown in FIG. 4, when the cord fastening device P of the present embodiment is attached to the loop L of the shade fabric body S, the hook opening interval of the hook portion 1 is easily expanded, and the hook portion 1 is pulled to the loop L. It is possible to easily carry out the hanging work.

It is to be noted that only the hook tip 11 is reduced in diameter, and the other portions of the hook 1 are formed to be relatively thick, so that the cord fastening device P once attached is attached to this hook. There is no concern that the tip 11 will easily come off due to elastic deformation.

Moreover, in this embodiment, since the spherical swelling portion 12 is formed at the most distal end of the hook tip 11 having the reduced diameter, the hook tip 11 having the reduced diameter is stuck into the tape T or the like. It does not hinder the hooking work and allows for smooth installation work.

Further, in the present embodiment, since the spherical bulging portion 12 is formed so as to project to the outside of the virtual plane A whose reference is the front of the body portion 2, as shown in FIG. The cord fastener P can be easily hooked on the loop L only by making the loop L along the front portion of the body 2.

The embodiment which is a specific example of the present invention is generally configured as described above, but the present invention is not limited to the above-mentioned embodiment, and various modifications can be made within the scope of the “claim for utility model registration”. Can be changed. For example, the depth of the hook portion 1 and other shapes of the cord fastening device can be variously designed according to the thickness and inner diameter of the loop L provided on the shade cloth S. It is possible.

[0019]

[Effect of the present invention]

 As described above with reference to the embodiments, in the cord fastening device according to the present invention, since the hook tip of the hook portion has a small diameter, when attaching the cord fastening device to the loop of the shade cloth, , It becomes easier to widen the hook opening interval of the hook part, and it becomes possible to easily hook the hook part to the loop.

In addition, since the spherical bulge is formed at the tip of the reduced-diameter hook tip, the reduced-diameter hook tip may pierce the tape or the like and hinder the hooking work. Without it, very smooth installation work is possible.

Further, if necessary, if the spherical bulging portion is formed so as to project outward from the front surface of the body of the cord fastening device, the loop can be run along the front surface of the body, It is possible to easily hook the hook part to the loop, and it is possible to significantly improve the work efficiency of attaching the cord fastener.
