Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pleated curtain which can be folded in a zigzag shape and which can be drawn out or folded in a horizontal direction.

[0002]

2. Description of the Related Art FIG. 3 shows an example of a horizontally drawn pleated curtain. A movable frame 2 is movably suspended and supported by a hanger rail 1 attached to an upper frame of a window or the like. At one end of the hanger rail 1, a base end of a curtain 4 is attached to a fixed frame 3 fixed to a wall or the like, and a tip of the curtain 4 is attached to the movable frame 2.

The curtain 4 is formed so as to be zigzag-foldable. When the movable frame 2 is pulled out along the hanger rail 1, the curtain 4 is pulled out along the hanger rail 1. When the movable frame 2 is moved toward the fixed frame 3, the curtain 4 is fixed to the movable frame 2. It is folded between the frames 3.

A guide cord 5 is penetrated through the curtain 4, and a base end of the guide cord 5 is connected to the fixed frame 3.
The front end is attached to the moving frame 2 so that the curtain 4 is prevented from being displaced.

When a rotational force in the cord winding direction is constantly applied to the cord winding shaft by an urging means such as a torsion coil spring, and the movable frame 2 is moved in the direction of the fixed frame 3, a guide is provided. The cord 5 is automatically wound around the cord winding shaft, thereby preventing the guide cord 5 from being loosened.

When the movable frame 2 is pulled out, the guide cord 5 is rewound from the cord winding shaft, and the urging means is charged.

[0007]

In the above-described horizontal pleat curtain, when the movable frame 2 is moved to the fixed frame 3, the guide cord 5 is wound around the same portion of the cord winding shaft. The winding diameter of the winding shaft increases.

Therefore, it is necessary to increase the size of the fixed frame 3 in order to accommodate such a cord winding shaft. SUMMARY OF THE INVENTION An object of the present invention is to provide a horizontal pleat curtain capable of reducing the size of a frame accommodating a cord winding shaft for winding a guide cord.

[0009]

In order to achieve the above object, according to the present invention, in the first aspect, a bias is applied to the cord winding shaft to apply a rotational force to the cord winding shaft in a guide cord winding direction. Means and moving means for moving the code winding shaft in the axial direction with the rotation of the code winding shaft.

According to a second aspect of the present invention, the cord winding shaft is provided in the fixed frame, and the urging means is constituted by a spring which is charged when the cord winding shaft is rotated in the guide cord rewinding direction. The moving means was configured by screwing a screw attached to the fixed frame to a screw attached to the cord winding shaft.

According to a third aspect of the present invention, the cord winding shaft is provided in the movable frame, and the urging means is constituted by a spring which is charged when the cord winding shaft rotates in the guide cord rewinding direction. The moving means was configured by screwing a screw attached to the moving frame to a screw attached to the cord winding shaft.

[0012]

FIG. 1 shows a fixed frame of a horizontally drawn pleated curtain embodying the present invention. In the present embodiment, since the configuration is the same as that of the conventional example except for the cord winding device in the fixed frame, the same components will be described with the same reference numerals.

In the fixed frame 11, a cord winding shaft 13 is rotatably supported by a bearing member 12. A slide shaft 14 is erected and fixed at the lower end of the fixed frame 11, and a screw is engraved on the outer peripheral surface of the slide shaft 14.

A shaft guide 15 is fitted to the lower end of the cord winding shaft 13, and a screw hole 16 is provided in the center of the shaft guide 15, and the slide shaft 14 is screwed into the screw hole 16. Have been combined.

Accordingly, when the cord winding shaft 13 is rotated, the shaft guide 15 is moved in the axial direction of the slide shaft 14, so that the cord winding shaft 13 moves up and down while rotating inside the fixed frame 11. It has become.

A guide cord 5 is wound around an intermediate portion of the cord winding shaft 13. A base end of a spring shaft 17 is fixed to the upper end of the fixed frame 11, and a spring end 18 is supported on the spring shaft 17 so as to be movable only in the axial direction of the spring shaft 17.

One end of a spring 19 composed of a torsion coil spring is attached to the spring end 18, and the other end of the spring 19 is connected to the spring shaft 17.
It is attached to.

When the cord winding shaft 13 is rotated in the direction in which the guide cord 5 is rewound, the spring 19 is charged. In the horizontally drawn pleated curtain configured as described above, if the movable frame 2 is pulled out along the hanger rail 1, the curtain 4 is pulled out. At this time, the guide cord 5 is rewound from the cord winding shaft 13, the code winding shaft 13 is rotated, and the spring 19 is charged.

When the movable frame 2 is moved toward the fixed frame 11 and the curtain 4 is folded, the cord winding shaft 13 is rotated by the urging force of the spring 19, and the guide cord 5 is wound around the cord winding shaft 13. Taken.

At this time, since the cord winding shaft 13 slides in the axial direction with the rotation thereof, the guide cord 5 is not wound around the same portion of the cord winding shaft 13 but is spirally wound. .

With such a horizontally drawn pleated screen, the following operational effects can be obtained. (1) Regardless of the length of the guide cord 5, the cord winding diameter of the cord winding shaft 13 is substantially constant.
Can be prevented from increasing in size. (2) It is possible to prevent the appearance of the pleated screen from deteriorating due to an increase in the size of the fixed frame 11.

The above embodiment can also be configured as follows. ○ Attach a male screw to one end of the cord winding shaft, attach a female screw to be screwed to the male screw on the fixed frame, and move the cord winding shaft in the axial direction with its rotation. I do.

A spiral spring or bamboo shoot spring is used in place of the torsion coil spring. ○ A structure such as a cord winding shaft provided in a fixed frame for winding a guide code is provided in a movable frame.

[0024]

As described above in detail, the present invention can provide a horizontal pleat curtain capable of reducing the size of a frame accommodating a cord winding shaft for winding a guide cord.
