[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a lift-type curtain, for example, a shade, and more particularly, a structure for preventing a lift-type curtain from being connected to an operation code by consolidating all lift codes at its ends. About.

[0002]

2. Description of the Related Art Conventionally, in an elevating curtain as described above, each elevating cord derived from the upper end of an operation cord attached to one side of a weight bar at the edge of the curtain underground passes through the rail and passes through a predetermined position in the rail. At the part of the roller arranged at the position, hang from the top of the roller so that it wraps around,
The ascending / descending operation was enabled by sequentially inserting the distal end into the insertion ring and tying the distal end to the lowermost insertion ring.

For this reason, when the curtain material becomes dirty and washing becomes necessary, the ends of the tied and fixed lifting cords are released from the lowermost insertion ring, the upper edge of the curtain material is removed from the rail, and the vertical direction is removed. It is necessary to remove each of the insertion rings aligned from the end of the lifting cord from the leading end side of the lifting cord, and finally to remove the curtain by removing the weight bar attached to the lower end of the operation cord from the curtain.

[0004]

However, when the curtain material is removed, the lifting cords that fall into the rails from one end of the rails and hang down at each roller are in an unstable state in which they are swung even by wind or the like. . For this reason, if a child or pet pulls the operation code that focuses the lifting code or the cap of the weight bar connected to this operation code by mischief, each operation code derived from the upper end of the operation code The lifting cord was lifted up and out of the rail, and pulled out of the roller guide rollers. Once the lifting cord has been pulled out of the roller,
It was extremely difficult to restore the cord because the rail groove was narrow and the direction of the lifting cord had to be bent 90 degrees.

That is, the conventional lifting type curtain has a problem that the lifting cord is easily detached when the curtain material is removed.

The present invention has been made in view of the above-mentioned difficulties, and has as its object to provide a structure for preventing a lifting cord from being removed unexpectedly when removing a curtain from a curtain.

[0007]

According to the present invention, the tip of a lifting cord is hung down through a roller in a rail and connected to an insertion ring at a lower portion of a curtain fabric, and the curtain is opened and closed by operating the end of the lifting cord. A lifting and lowering curtain having a bump at the tip of the lifting cord, and having a retaining portion for preventing the passage of the bump, by moving the lifting cord to the lower position of the roller. It is characterized in that it is a structure for retaining a lifting cord of a lifting curtain mounted on a vehicle.

[0008]

The lifting cord retaining structure of the lifting curtain according to the present invention is formed, for example, by forming a knot at the end of the lifting cord to form a knot, and a part of the lifting cord in the rail and a part hanging down from the rail. On the lower side of the roller at the branch point with, for example, at the lower position of the roller, a retaining member having a retaining portion that allows the passage of the thickness of the cord but prevents the passage of the bump described above is provided. By mounting, even the tip of the cord enters the rail and is prevented from being pulled out of the roller.

[0009]

As described above, according to the present invention, since the lifting cord does not come out of the roller, the curtain fabric can be easily attached and detached with ease.

[0010]

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a rear view of the elevating curtain 1 which is manually opened and closed vertically.

The upper edge of the curtain material 2 is attached to the front of the rail 3 and corresponds to the lower edge of four ring tapes 4 arranged vertically in the horizontal direction at appropriate intervals. Is equipped with a weight bar 5. Each ring tape 4 is provided with a predetermined number of insertion rings 6.
.., Which will be described later. Caps 5a, 5 attached to both ends of weight bar 5
An operation code 8 is connected to one 5a (left side in the drawing) of b, and an elevating code 7... The equalizer 9 is used for each ring tape 4 ...
Are moved together by a single operation code 9.

Each of the lifting cords 7... Extends from the stopper 10 attached to one end (left side in the drawing) of the rail 3 into the rail 3. Rollers 11 are provided in the rail 3 at positions corresponding to the respective ring tapes 4 including the stoppers 10, and the lifting cords 7 hang down at the portions of the rollers 11. The suspended lifting cords 7 are inserted into the retaining members 12 attached to the lower side of the rollers 11 and then further inserted into the respective insertion rings 6 on the ring tape 4.
The distal ends are connected to the lowermost insertion rings 6a. A knot 13 is formed at this tip portion with a slight excess of a knot.
The bump 13 has such a size that it can pass through each of the insertion rings 6.

The structure of the above-mentioned rollers 11 will be described with reference to FIG. 3 taking one of the rollers 11... A mounted in the rail 3 as an example.

The roller 11 is large enough to be inserted into the rail 3 and is rotatably supported on one side of a mounting bracket 14 having a substantially concave cross section. It has a number of serrated irregularities along its length.

The mounting bracket 14 having the rollers 11 is fixed to the rail 3 by the bottom plate 15 of the mounting bracket 14,
L-shaped bracket 1 with an L-shaped cross section attached to this mounting bracket 14
6 and both side portions 17 forming a groove under the rail 3
Of the mounting plate 14 at this time.
5 and is fixed underneath.

The stopper 12 is, as shown in FIG.
It is made of metal in a substantially long U-shaped symmetrical shape, and the gap between the curved distal ends is set at an interval at which the lifting cord 7 can smoothly move and a width at which the bump 13 cannot pass. A stop 19 is formed. A gap having the same width as the retaining portion 19 is formed on the opposite side, but a wide portion 20 is formed at a part of the end. This is because the shape of the fixing screw 18 is made to correspond to the axis of the fixing screw 18 so that the fixing screw 18 can be easily mounted.

In the elevating curtain 1 constructed as described above, even if the elevating cords 7 simply hang down from the upper side of the rollers 11, the elevating cords 7.
Prevent extraction from 1 ...

That is, assuming that the curtain fabric 2 is removed from the liftable curtain 1 in the state shown in FIG. 2 for washing or image change, for example, the lift codes 7 passing through the rail 3 are: In the part hanging down from the rollers 11, there is no means for keeping the position fixed, such as the lowermost insertion ring 6 a, and the state becomes simply unstable, and the hanging down from one of the stoppers 10. The cap 5a of the weight bar 5 only hangs at the end of the operation code 8 at the portion connected to the operation code 8,
This is also an unstable state. In addition, when a child pulls the operation code 8 or the cap 5a hanging on one side of the rail 3, the operation code 8
Are lifted up. However, even if each lifting cord 7 is pulled up, the bump 13 formed at the tip of the lifting cord 7 is caught by the retaining portion 19 of the retaining member 12 provided below the rollers 11. The lifting code 7 ... is the roller 11 ...
Is prevented from being pulled out.

As shown in FIG. 1, since the retaining portion 19 is set to have such a width as to prevent the lifting cord 7 from passing through the knob 13, the knob 13 is prevented from rising by the retaining portion 19, so The resulting tip projects below the lower surface of the rail 3.

[0021] Therefore, the work of installing a clean curtain or a new-pattern curtain can be performed comfortably and comfortably.
Easy to do.

Also in the work of erection of the curtain, it is possible to prevent the lifting cords 7 that have been applied once from dropping out unexpectedly, and it is possible to expect a reliable and quick work.

As described above, an embodiment of the present invention has been described. However, the present invention can employ a configuration other than the above.

For example, in the above embodiment, the retaining member 12 is sandwiched under the bottom plate 15 of the mounting member 14, but the L-shaped member 1
6 may be located above.

Also, the retaining portion 1 at the tip of the retaining member 12
The shape of 9 may be hook-shaped so that the elevating cord 7 can be inserted from the side, and such a retaining fitting 12 may be formed on the mounting fitting 14 of the roller 11 in advance.

Further, the bumps formed on the lifting cord may be formed by attaching a spherical member by crushing or the like in addition to forming a knot.
