Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a fastening device for accordion curtains, and more specifically, it is a device that freely adjusts the length of the cord according to changes in the folded width of the accordion curtain. The present invention relates to an improvement in a detent cord attachment part.

[Prior Art] This type of accordion curtain is formed into an elastic bellows shape, and when it is opened and folded, the folded curtain tends to roll back and expand somewhat due to the elasticity of the bellows part.

[Problem to be solved by the invention] In order to solve this problem, a drawer cord connected between both frame columns is connected to one of the frame columns connected to both ends of the telescopic framework of the accordion curtain in a spiral shape using a spiral spring. A pulling body is fixedly installed to be wound inside the curtain, a cord connected to the above-mentioned pull-out cord is attached to the other frame pillar, and the curtain is automatically folded by pulling the frame pillar in the folding direction. When the curtain is folded, the elasticity of the curtain material prevents it from folding back.

However, as folding wires come with use, the folded width of the accordion curtain becomes thinner than when newly installed, and the cord is attached between the end of the cord wrapped in the pulling body and the other frame pillar. The problem is that the length of the cord does not allow it to completely hold the folded state without any gaps, and the accordion curtain appears to be open by the amount that it has shrunk.

In such cases, it is necessary to adjust the length of the cord to adjust the attachment position. Up until now, the cord had been adjusted by removing the bellows-like covering material, but this work was said to be extremely complicated. There was a problem.

The purpose of this invention is to make it possible to easily adjust the length of the cord without removing the covering material, in order to eliminate the above-mentioned problems.

[Means for solving the problem] The purpose of this invention described above is to stretch the facing material between the left and right frames, attach a cord winding device to one frame, and attach the cord to the other frame. The fixing device for the accordion curtain consists of a mounting hole formed in the inner frame side plate of the other frame to which the covering material is fixed, and a cord fitting attached to this mounting hole, and the cord fitting includes: This is achieved by using a cylindrical body having a through hole passing through the base, and a cord attaching portion having a locking flange provided at the end of the cylindrical body.

[Function] Before fitting the mounting member, the length of the cord can be adjusted by first passing the end of the cord that has passed through the space of the upholstery of the accordion curtain from the locking flange side through the through hole of the fixture as described above. Pull it out to the outside, and with the curtain completely closed, wrap its end through one of the grooves toward the cylindrical body, leave a size that will allow it to be wrapped, for example, once and a half around the outer circumference of the cylindrical body, and tie a knot. The cord is attached by wrapping the cord around the cylindrical body the number of times specified above, and returning the knot from the other split groove to the locking collar side.

The above-mentioned loosening occurs as the accordion curtain bends during use, and if you want to adjust this loosening, remove the mounting member, remove the cord by reversing the installation procedure above, and then repeat the above procedure again. By installing it, you can easily adjust the cord length even after installing the curtain.

[Example] Examples will be described with reference to the drawings.

Figure 1 is a configuration diagram of an accordion curtain implementing this invention.The accordion curtain 1 is stretched between pillars 2 and 3, and fixed to the lower side of a horizontal frame 4 that is suspended above the pillars 2 and 3. It is suspended from a guide rail 5 via a runner 6 so as to be freely movable. Frames 7 and 8 made of aluminum alloy or the like are fixed to both ends of the accordion curtain 1, and a bellows-shaped covering material 9 of the accordion curtain 1 is stretched between the frames 7 and 8.

A housing 11 constituting a part of a cord winding device 10 as shown in FIG. A fixture 20 for a detent prevention cord of this invention, which will be described later, is fixed at a position on the inner surface facing this.

As shown in FIG. 2, the cord winding device 10 includes a housing 11 integrally molded from synthetic resin or the like, and a spring 13 that locks the cord 12 inside the housing 11. A locking portion 16 having
A mainspring 19 is attached between a cord winding frame 17 to which the end of the cord is attached, and a pivot 18 of this winding frame and the winding frame, and as the cord is pulled out, the mainspring 19 moves. When the external force applied to the wound cord 12 is released, the cord winding frame 17 can be automatically rewound by the elasticity of the mainspring 19.

FIGS. 3 to 6 show the structure of the fixture 20 for the detent prevention cord of this invention, and this fixture is integrally formed from synthetic resin or the like.
A rectangular base 21 opened at both longitudinal ends of the elongated mounting hole 22, a pair of mounting hooks 23 protruding from one surface of the base 21, and a support member 24 formed on the same surface in the direction of the elongated hole. A cylindrical body 26 having a through hole 25 passing through the base and a locking collar 28 having a split groove 27 reaching the through hole at the end thereof are attached to the cord attachment part 29. It has an established structure.

As shown in FIGS. 4 and 5, this mounting tool 20 described above has a mounting hole 8 with a locking pawl 82 formed in the inner frame side plate 81 inside a substantially C-shaped frame 8.
3, the cord attachment portion 29 is inserted into the frame, and the hook portions of the pair of attachment hook pieces 23 are attached to the frame side plate 8.
A pair of locking claws 8 that are locked inside of 1 and raised up.
2 are inserted into the elongated holes 22 and bent.

In addition, as shown in FIGS. 4 to 6, the ends of the facing material 9 are also attached to the outer frame side plates 8 along the side surfaces of the frame body 8.
After being bent inward from the opening 84 on the 5th side and inserted, it is locked by fitting the synthetic resin attachment member 30.

To adjust the length of the cord, as described above, before fitting the mounting member 30, the end of the cord 12 passed through the space of the covering material 9 of the accordion curtain 1 is
The through hole 25 of the fixture 20 is shown in FIGS.
Once through the curtain, pull it out from the locking collar 28 side, and with the curtain completely closed, turn the end of the curtain from one of the grooves 27 to the cylindrical body 26 side. A knot 12a is made by leaving enough space to be wrapped half a turn, and the cylindrical body is wound the number of times, and the knot is passed from the other split groove 27 to the locking flange 2.
The cord 12 is attached by returning it to the 8 side.

The above-mentioned loosening occurs as the accordion curtain bends during use, and in order to adjust this loosening, remove the mounting member 30, remove the cord 12 in the reverse order of the above-mentioned installation procedure, and then repeat the above-mentioned procedure again. By following the installation steps, you can easily adjust the cord length even after installing the curtain.

[Effects of the invention] Since this invention is configured as described above, it produces the effects described below.

A mounting hole is provided on the inner frame side plate of the frame body, the cord is guided inside the frame body, and the length of the cord can be adjusted and fixed from the opening on the outer frame side plate of the frame body, so for example, the end of the cord can be fixed. By inserting it into the through hole from the base side, pulling it out from the locking flange side through the split groove and pulling it out to the cylindrical part side, wrapping it around the cylindrical body, and then tying a knot and inserting it into the split groove to lock it. The cord length can be easily adjusted at a later date, and it is easy to attach to the frame and does not require fixing devices such as screws.
