Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide member for guiding an elevating cord of a tuck-up curtain along a curtain material.

[0002]

2. Description of the Related Art In a tuck-up curtain, curtain material is suspended and supported from a head box, and the lower ends of a plurality of lifting cords hung from the head box are attached to the lower end portion of the curtain material.

When the lifting cord is pulled up by operating the operating device, the curtain material can be folded upward. In such a tuck-up curtain, a hanging tape is attached to the curtain material, a guide member is attached to the hanging tape, an elevating cord is inserted through the guide member, and the elevating cord is attached to the curtain material. You will be guided.

It is desirable that the guide member has a small frictional resistance with the elevating cord in order to reduce the operation force when the curtain material is being moved up and down. Registered Utility Model Bulletin No. 30
Japanese Patent No. 39634 discloses a guide member in which a ring portion and a hook portion are formed in an orthogonal state to reduce frictional resistance between the lifting cord and the ring portion.

[0005]

However, in the guide member as described above, when the curtain material is moved up and down, the insertion opening formed in the hook portion is caught by the curtain material or the hanging tape, and the curtain material is smoothly moved. There is a problem that the lifting operation may be hindered.

An object of the present invention is to provide an elevating and lowering cord guide device for a tuck-up curtain which can smoothly elevate and lower the curtain material.

[0007]

According to a first aspect of the present invention, a curtain material is hung and supported from a head box, and lower ends of a plurality of lifting cords that are hung from the head box are attached to a lower end portion of the curtain material. An elevating and lowering cord guide device for a tuck-up curtain, in which a guide member is attached to a loop provided on the curtain material, the elevating and lowering cord is inserted through the guide member, and the elevating and lowering cord is held along the curtain material. In the guide member, one ends of the upper ring and the lower ring are connected by a connecting portion, and the loop supports the connecting portion.

According to a second aspect of the present invention, at least one of the upper ring and the lower ring is provided with an opening through which the lifting cord can be inserted. In claim 3, the upper ring and the lower ring are
The loops are parallel to each other, and the upper ring and the lower ring can be held horizontally by supporting the connecting portion with the loop.

In the present invention, the upper edge of the upper ring and the lower edge of the lower ring are curved. In claim 5, a plurality of the loops are provided adjacent to the hanging tape attached to the curtain material in the left-right direction.

BEST MODE FOR CARRYING OUT THE INVENTION In the comb curtain shown in FIG. 1, a curtain material 2 is suspended from a head box 1 and a weight bar 3 is accommodated at the lower end of the curtain material 2.

A plurality of lifting cords 4 are hung from the head box 1 on the back side of the curtain fabric 2, and the lower ends of the lifting cords 4 are attached to the lower part of the curtain fabric 2.

A plurality of retaining tapes 5 are sewn on the back surface of the curtain material 2 in the horizontal direction and at the same intervals in the vertical direction. A guide member 6 is attached to each of the hanging tapes 5 so as to form a straight line in the vertical direction, and the lifting cord 4 is inserted through the guide member 6.

An endless ball chain 7 is suspended from one end of the head box 1. By operating the ball chain 7, the lifting cord 4 can be pulled up or lowered.

Therefore, when the lifting cord 4 is pulled up,
When the curtain material 2 is folded up from below and the elevating cord 4 is lowered, the curtain material 2 is returned to the state in which it is suspended and supported by the head box 1 from the upper portion thereof.

A specific structure of the guide member 6 will be described with reference to FIG. The guide member 6 is made of synthetic resin and has a shape in which one side of the upper ring 8a and the lower ring 8b are connected by a connecting portion 8c.

The upper edge of the outer periphery of the upper ring 8a and the lower ring 8
The lower edge of the outer peripheral portion of b is formed in a curved surface so as not to be caught by the curtain material 2. The guide member 6
An opening 9 is formed in the lower ring 8b, and the lifting cord 4 can be inserted into the lower ring 8b from the outside through the opening 9.

As shown in FIG. 3, a plurality of loops 10 are formed in the left-right direction at the mounting position of the guide member 6 of the retaining tape 5, and the guide member 6 is supported by any one of the loops 10. .

The procedure for attaching the guide member 6 to the loop 10 is to insert the lifting cord 4 into the upper ring 8a in advance, and in that state, lower the ring 8b to the loop 1 as shown in FIG.
0, and the connecting portion 8c is supported by the loop 10 as shown in FIG. Then, the upper ring 8a and the lower ring 8b of the guide member 6 are held substantially horizontally.

Next, when the elevating cord 4 is inserted through the opening 9 of the lower ring 8b into the lower ring 8b, the elevating cord 4 is moved by the upper ring 8a and the lower ring 8b of the guide member 6 supported by the retaining tape 5. You will be guided.

Further, when the mounting position of the guide member 6 with respect to the hanging tape 5 is changed, the lower ring 8b of the guide member 6 is changed.
Remove the lifting cord 4 from the
Remove from.

Then, the lower ring 8b is attached to the adjacent loop 10.
When the lifting cord 4 is inserted through the lower ring 8b, the change of the mounting position of the guide member 6 is completed. With the comb-up curtain configured as described above, the following operational effects can be obtained.

(1) By operating the ball chain 7, the curtain material can be raised and lowered. (2) The guide member 6 for guiding the elevating cord 4 along the curtain material 2 can be guided by the upper ring 8a and the lower ring 8b which are held substantially horizontally with respect to the curtain material 2. Therefore, the lifting cord 4, the upper ring 8a and the lower ring 8
The frictional resistance with b can be reduced.

(3) Since the guide member 6 does not have a sharp portion, it is possible to prevent the curtain material 2 or the hanging tape 5 from being caught by the guide member 6. (4) By removing the lifting cord 4 from the lower ring 8b, the guide member 6 can be easily attached to and removed from the latching tape 5 with the lifting cord 4 inserted in the upper ring 8a.

(5) The mounting position of the guide member 6 with respect to the hooking tape 5 can be easily changed. (6) The upper ring 8a and the lower ring 8b of the guide member 6 are annular, and the upper edge of the outer periphery of the upper ring 8a and the lower ring 8b are
Since the lower edge of the outer peripheral portion is formed into a curved surface and the guide member 6 has no other sharp portion, it is possible to prevent the curtain material 2 from being caught.

The above embodiment can be modified as follows. The opening 9 may be provided in the upper ring 8a. Further, it may be provided on both the upper ring 8a and the lower ring 8b. The opening 9 may not be provided in either the upper ring 8a or the lower ring 8b. In this case, loop 10
The guide members 6 are attached to the
The lifting cord 4 may be inserted through the a and the lower ring 8b.

[0026]

As described above in detail, the present invention can provide an elevating cord guide device for a tuck-up curtain that can smoothly elevate the curtain material.
