Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation cord mounting structure for vertically moving a screen of a roller blind.

[0002]

2. Description of the Related Art Conventionally, there is a type of roller blind as shown in FIG. That is, both ends of a winding shaft 2 are rotatably supported by a frame 1 fixed to an upper frame of a window, a screen 3 is suspended from the winding shaft 2, and a weight is attached to a lower end of the screen 3. Bar 4 is attached. Then, an operation cord 5 is hung down on an intermediate portion in the longitudinal direction of the weight bar 4, and by operating the operation cord 5, the screen winding device arranged in the winding shaft 2 can be driven to move the screen 3 up and down. Has become.

A structure for attaching the operation string 5 to the weight bar 4 will be described with reference to FIG. 4. A groove 6 is formed on the lower surface of the weight bar 4 over the entire length in the longitudinal direction of the weight bar 4.
Is formed, and the inside of the groove 6 is wider than the opening. Then, the stopper 7 to which the upper end of the operation cord 5 is attached is inserted into the groove 6 from one end of the weight bar 4 to suspend and support the operation cord 5 from the weight bar 4, and in this state, as shown in FIG. Further, caps 8 are fitted on both ends of the weight bar 4.

[0004]

However, in the above-mentioned structure, the stopper 7 is provided with the groove 6 as the operation cord 5 is operated.
Move in the longitudinal direction of the weight bar 4 and move the operation cord 5
May be hung from one end of the weight bar 4, and in such a state, the lifting and lowering operation of the screen 3 is hindered.

Therefore, there has been proposed a structure in which the stopper 7 is formed in a corrugated shape to increase the friction with the inner surface of the groove 6 to prevent the stopper 7 from moving in the groove 6. With such a configuration, there is a problem that the work of inserting the stopper 7 into the groove 6 becomes complicated at the time of assembly, and the movement of the stopper 7 cannot be completely prevented.

An object of the present invention is to provide a mounting structure which can easily attach an operation cord of a roll blind to a weight bar and prevent the operation cord from moving in the longitudinal direction of the weight bar.

[0007]

In order to achieve the above object, the present invention rotatably supports both ends of a winding shaft on a frame, suspends a screen from the winding shaft, and weights the lower end of the screen. In a roll blind in which a bar is attached and an operation string is hung from the weight bar, a mounting hole is provided on the lower surface of the weight bar, and the operation string can be inserted into a string stopper fitted in the mounting hole. An insertion hole is provided, and a pair of elastic locking pieces are provided on both sides of the insertion hole of the cord stopper, and the elastic locking pieces are attachable to and detachable from the mounting hole when elastically bent in a direction toward each other. A knot of a size that prevents the elastic locking piece from bending when positioned between the elastic locking pieces and prevents the operation string from slipping out of the insertion hole at the tip of the operation string inserted into the insertion hole. To form The knot in a state of fitted into the elastic latching pieces mounting hole of Kihimo stopper and is positioned in the elastic locking pieces.

[0008]

By the above means, the elastic locking piece of the cord stopper is fitted into the attachment hole of the weight bar, and the knot of the operation string is positioned between the elastic locking pieces, so that the upper end of the operation string is moved relative to the weight bar. It is mounted immovably.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment embodying the present invention will now be described with reference to FIG.
2 and FIG. The same components as those of the conventional example will be described with the same reference numerals.

As shown in FIG. 2, the lower end of the screen 3 is wound around and the surface of the weight bar 11 is covered with the screen 3.
2 is formed, and a string stopper 13 can be fitted into the mounting hole 12 from below. That is, the cord stopper 1
3 has a pair of elastic locking pieces 15 formed on an elliptic plate-shaped base plate 14 having an outer diameter larger than the diameter of the mounting hole 12, and the distance between the outer surface of the base end portion of each elastic locking piece 15 is set to be larger than that of the mounting hole 12. The elastic locking piece 15 has a diameter substantially the same as that of the hole 12, and a protrusion 16 is formed on the outer surface of the middle portion of the elastic locking piece 15.
A slope 17 is formed at the upper end portion of the so as to extend obliquely upward to the outside.

As shown in FIG. 1, an insertion hole 18 is formed on the base plate 14 between the elastic locking pieces 15, and the operation string 5 can be inserted into the insertion hole 18. And
A knot 19 is formed on the upper end of the operation string 5, and the knot 19 is located between the elastic locking pieces 15 when the operation string 5 is suspended and supported from the weight bar 11.

In order to attach the operation cord 5 to the weight bar 11 in the above structure, the upper end of the operation cord 5 is inserted into the insertion hole 18 of the cord stopper 13 as shown in FIG.
A knot 19 is formed at the upper end to prevent the knot 19 from coming off the insertion hole 18. Further, the knot 19 is sized so as to prevent the elastic locking pieces 15 from being bent in a direction toward each other when positioned between the elastic locking pieces 15 as shown in FIG.

Next, with the upper end portion of the operation cord 5 inserted into the attachment hole 12 of the weight bar 11, the cord stopper 13 is attached.
When the slant surface 17 of the elastic locking piece 15 is applied to the end edge of the mounting hole 12 and the string stopper 13 is pushed upward, the slant surface 17
The elastic locking pieces 15 bend in a direction in which the elastic locking pieces 15 approach each other, and when the projection 16 is retracted into the mounting hole 12 as shown in FIG. 1, the elastic locking pieces 15 return to their original positions.

When the operation string 5 is pulled downward in this state, the knot 19 is located between the elastic locking pieces 15 and the elastic locking pieces 15 are located.
Since the protrusion 16 is reliably engaged with the edge of the mounting hole 12, the string stopper 13 is prevented from coming off the mounting hole 12.

When the operation cord 5 is removed from the weight bar 11, the operation cord 5 is lifted to the information and the knot 1
9 is moved upward from between the elastic locking pieces 15, and the string stopper 13 is removed from the mounting hole 12 in this state, the operation string 5
Can be easily removed from the weight bar 11.

As described above, in this operation cord attaching structure, the knot 19 is formed at the upper end of the operation cord 5 inserted through the insertion hole 18 and the cord stopper 13 is fitted into the attachment hole 12, so that the upper end of the operation cord 5 is easily formed. The weight bar 11 is securely and reliably attached to the weight bar 11, and the attachment position does not move in the longitudinal direction of the weight bar 11. Further, since the operation cord 5 is not inserted from one end side of the weight bar 11, the lower end portion of the screen 3 can be wound around the weight bar 11, which is aesthetically preferable.

[0017]

As described above in detail, according to the present invention, the operation cord of the roll blind can be easily attached to the weight bar, and the movement of the weight in the longitudinal direction of the weight bar can be prevented.
