Description

The present invention relates to a flat curtain device capable of forming a wave.

The flat curtain device described in Patent Document 1 is provided as an example of a flat curtain device capable of alternately forming uneven wave-shaped folds on the front side and the back side of a flat curtain of a type in which no folds are provided on the upper part of the curtain. In the flat curtain device, in order to form uneven wave-shaped folds alternately on the front side and the back side of the curtain, adjacent points at substantially the center of the wave amplitude have a predetermined length shorter than the half-wave wave length of the curtain fabric. In a curtain device that connects runners to each other with a string body, a hook through hole portion perpendicular to the longitudinal direction of the curtain rail is provided on the curtain tape at the upper end of the curtain to correspond to the hole pitch at approximately the center of the wave amplitude. It has a configuration in which a hanging hook having a raised foot pitch is attached.

In the flat curtain device, since it is possible to alternately form uneven wave-shaped folds on the front side and the back side of the flat curtain, a runner with a string body having a predetermined length shorter than the half-wave wave length of the curtain fabric is used. It is essential to combine them with each other.

However, in the case of the flat curtain device in which runners are connected to each other by a string body, since the string body is housed in the curtain rail, the string body is slack inside the curtain rail when the curtain is opened and closed. It becomes a state of hanging or extending to a horizontal state. Therefore, there is a risk that the string will get entangled with the runner inside the curtain rod.

Further, since the curtain rod constituting the flat curtain device in which runners are connected to each other with a string body is a dedicated product, when the flat curtain device is to be configured by using a flat curtain, only the dedicated runner is used. However, there was an uneconomical need to prepare a curtain rod for this purpose. Further, when changing the existing curtain device to the flat curtain device, it is necessary to remove the already installed curtain rod before installing the dedicated curtain rail, which is a laborious and troublesome work. There was a problem that required a process.

The amount of protrusion of the loop-shaped piece 36 from the side edge 35 is set to, for example, 5 mm, and the thickness of the loop-shaped piece 36 is set to, for example, 0.5 mm.

The locking portion 14 is provided on each hook 9 with the same configuration. For example, as shown in FIG. 4B, the locking portion 14 is located in the vicinity of the upper end 37 of the hook 9 and the rear surface portion 5 of the flat curtain 2. It is configured to be provided close to (FIG. 2) and provided with a holding groove 40 provided with a retaining groove 39 at the inlet portion 38, which is opened at the outer surface portion 65 of the semicircular bent portion 27. In this embodiment, the locking portion 14 includes the holding groove 40 and the lower surface portion of the hook 9 (in the present embodiment, the inner arcuate surface portion 48a of the semicircular bent portion 27 of the hook 9) 48. It is composed of a portion 51 between.

The groove depth of the holding groove 40 is set to, for example, 2.6 mm. Further, the loop-shaped piece 36, which is the mounting portion 13, can insert the hook 9 from the lower end 41 thereof. Specifically, the falling portion 31 can be inserted upward from the lower end 41 thereof.

In this embodiment, the groove wall of the holding groove 40 near the rear surface portion 5 (FIG. 2) is configured as a standing piece 42 protruding upward. On the inner surface of the upper end portion of the standing piece 42, for example, a retaining convex portion 43 having a triangular cross section is projected inward, and the retaining convex portion 43 constitutes the retaining portion 39. There is. The height of the upper end 45 of the standing piece 42 is set so as not to interfere with the operation of hooking the hook 9 on the hanging ring 8 and the hooked state of the hook 9.

Therefore, when the flat curtain device 1 is configured, as shown in FIG. 6, the hook 9 is attached to the loop-shaped piece 36 and the lower end thereof is attached to the loop-shaped piece 36 in a state where the flat curtain 2 is not attached to the curtain rail 6. It is inserted from 41 and the loop-shaped piece 36 is moved to the vicinity of the position where the holding groove 40 is present, as shown by an arrow in FIG. When the flexible tape-shaped piece 33 is accommodated in the holding groove 40 in this state, the flexible tape-shaped piece 33 (the linear member 12) is supported from below by the bottom portion 46 of the holding groove 40. (FIGS. 4 (B) (C)). As a result, the loop-shaped piece 36 is supported by the linear member 12 so as not to slide down the rising portion 23 of the hook 9. Then, the linear member 12 engages with the retaining groove 39 and does not separate from the holding groove 40.

Therefore, as shown in FIGS. 4 (B) and 4 (C), the loop-shaped piece 36 (the mounting portion 13) has the holding groove 40 and the lower surface portion of the hook 9 (in the present embodiment, the above-mentioned). The hook 9 is engaged with the locking portion 14 configured as the space 51 between the inner arcuate surface portion 48a) 48 of the semicircular bent portion 27, is supported by the linear member 12, and is in the supported state. Is retained. In short, as described above, the mounting portion 13 is fixedly mounted on the upper portion 10 set near the upper end of the hook 9 and closer to the rear surface portion 5 (FIG. 2) of the flat curtain 2. It will be. After the regulation linear member 11 is attached to the upper portion 10 of all the hooks 9 in this way, when these hooks 9 are hooked on the hanging ring 8 of the runner 7, the flat curtain 2 is attached to the curtain. It can be hung on the rail 6 (Fig. 1).

Therefore, when the flat curtain 2 is closed, as shown in FIG. 5, wave-shaped folds 50 having good-looking irregularities can be alternately formed on the front side and the back side of the flat curtain 2. The first reason is that, as shown in FIGS. 1 and 2, the linear member 12 is located above the upper edge 15 of the flat curtain 2, so that the flat curtain 2 is closed when the flat curtain 2 is closed. This is because the linear member 12 can be prevented from coming into contact with the upper edge 15 of the flat curtain 2, and the linear member 12 can be prevented from inhibiting the formation of the wave-shaped folds. Secondly, since the loop-shaped piece 36 is fixed to the hook 9, the distance between the hooks 9 and 9 is required to be held by the linear member 12.

As described above, in the present invention, since the mounting portion 13 can be mounted on the upper portion 10 of the hook 9 in a fixed state, the mounting position of the mounting portion 13 (loop-shaped piece 36) is set to the hook 9. It can be brought closer to the hooking portion 46 (FIGS. 1 and 2) for the runner. Therefore, the closing operation of the flat curtain can be lightly performed while sequentially tensioning the hook-to-hook linear members 47 (FIGS. 1 and 5) that require the distance between the hooks 9 and 9.

Further, in the flat curtain device 1 according to the present invention, the regulation linear member 11 is arranged along the upper portions 10 of each of the hooks 9 in a parallel state, and the wire has flexibility. A configuration is adopted in which the shaped member 12 is fixedly attached to the upper portion 10 of each hook 9. Therefore, like the flat curtain device according to Patent Document 1 in which runners are connected to each other with a string body, the linear member 12 having a string shape or a tape shape when the curtain is opened and closed is in a slackened state or is horizontal. Even if the linear member 12 is extended to the state, the problem that the linear member 12 is entangled with the runner inside the curtain rail does not occur.

Further, the flat curtain device 1 according to the present invention is different from the conventional flat curtain device in which runners are connected to each other by a string body, and is hooked on a runner 7 slidably suspended from a curtain rail 6. Adjacent hooks 9, 9 are connected to each other by the linear member 12 of the regulated linear member 11 arranged along the upper portion 10 of each of the hooks 9. Therefore, according to the present invention, it is not necessary to use a special curtain rod as in the conventional flat curtain device, and there is an advantage that the flat curtain device can be economically configured by using the attached curtain rod as it is. be.
