Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) This invention relates to a fixture for stably supporting a repair slat of a blind on a ladder cord.

(Prior art) In order to replace a slat that has been broken due to wind from outside the window, a repair slat with a notch for inserting the blind lifting cord is used as described in Japanese Utility Model Publication No. 57-22000. A lifting cord was inserted into the slat, and a fixture was fitted to the slat so as to close the notched opening. That is,
The fitting was formed from a thin sheet of metal and was fitted onto the slat by bending the ends against the side edges of the slat and closing the notches.

(Problem that the invention attempts to solve) Conventional slat fixtures as mentioned above are made of metal plates, so in order to ensure strength, it is necessary to increase the thickness of the plate. Then, it takes a lot of effort to bend the ends, and
Once fitted, it was not easy to remove the fitting from the slat. In addition, there was a problem in that the end portions were easily bent when repeatedly bent and stretched, making them unsuitable for repeated use.

Structure of the device (Means for solving the problem) In order to solve the above problem, this device folds one end in half to form a bent part through which the slat can be inserted, and the upper and lower sides of the bent part are bent in half. A pair of upper and lower pieces are respectively protruded from the upper and lower pieces, a gap is provided between each of the upper and lower pieces to allow the lifting cord to pass through, and a gap is provided between the upper and lower pieces to allow the slat to be held therebetween. A locking pawl for locking the slat between the lower piece and the bent portion is provided at the tip of the lower piece.

(Function) The fixture 1 configured as described above has a lifting cord 9.
When the repair slats 7, 15 are fitted with the notches 8, 17 for insertion, the lifting cord 9 is stably supported within the notches 8, 17 and is fitted with the bent portion 2 on the notch side. The notches 8 and 17 are connected by the bent portion 2, and the strength of the repair slats 7 and 15 against bending and twisting is ensured.

(Example) Below, a first example embodying this invention will be described with reference to the drawings.A fixture 1 for attaching a replacement slat is integrally formed of synthetic resin, and is folded in two at one end. A bent portion 2 is formed,
A pair of upper pieces 3 and a pair of lower pieces 4 are respectively protruded in parallel from the upper and lower sides of the bent portion 2 at the same distance. The portions from the bent portion 2 to the upper and lower pieces 3 and 4 are slightly curved to match the slats, and the slats are inserted between the upper and lower sides of the bent portion 2 and between the upper and lower pieces 3 and 4. A gap is provided for this purpose.

The lower piece 4 is longer than the upper piece 3, and a total of four locking claws 5 are provided on the top surface of the lower end, and the slat can be supported between the locking claws 5 and the bent portion 2. A recess 6 for hanging a ladder cord is formed in the center of the edge of the bent portion 2.
The repair slat 7, which is attached by such a fixture 1, has an insertion hole 8 at one side edge thereof, through which a lifting cord is inserted.

Now, in order to replace a damaged slat using the fixture 1 constructed as described above, as shown in FIG. 2, insert the lifting cord 9 into the insertion hole 8 of the repair slat 7, The opening of the insertion hole 8 is inserted into the bent portion 2 of the fixture 1, and the other end edge is engaged with the locking claw 5. If the repair slat 7 is supported by the ladder cord 10 in this state, the opening of the insertion hole 8 will be closed by the fixture 1.
The lifting cord 9 is stably supported within the insertion hole 8.

The slat fixture 1 as described above has each upper piece 3
The lifting cord 9 is avoided by the gap between the lower piece 4 and the repair slat 7, and both sides of the insertion hole 8 of the repair slat 7 are supported by the upper piece 3 and the lower piece 4, and the openings of the insertion hole 8 are connected. Since it can be fitted into the slat 7, it is possible to completely compensate for the decrease in strength of the slat 7 due to the provision of the insertion hole 8 with one end open, that is, the decrease in strength against bending, twisting, etc. In addition, since this fixture 1 has a structure in which the bent portion 2 and the locking claw 5 are fitted to both ends of the slat 7, the repair slat 7 can be attached extremely easily, and it is integrally molded with synthetic resin. Therefore, it is easy to increase the wall thickness to ensure strength, and the slats 7 can be easily attached regardless of the increase in wall thickness.

Furthermore, the slat 7 can be easily removed from the fixture 1, and the fixture 1 is not likely to deteriorate due to attachment and detachment of the slat 7, so it can be used over and over again.

Next, a second embodiment embodying this invention will be described with reference to FIG.
1 is a pair of lower piece tip portions that are cut out and brought into close contact with each other through a cut 12, so that an insertion hole 13 for inserting the lifting cord 9 is formed between both lower pieces 4, and a rudder is provided outside the cut 12. code 1
A concave portion 14 for hanging a 0 is formed, and the rest is the same as the fixture 1 of the previous embodiment. and,
Repair slat 15 to which this fixture 11 is attached
A notch 17 for guiding the lifting cord 9 into the insertion hole 16 is provided between the insertion hole 16 of the lifting cord 9 and the edge of the slat.

To use such a fixture 11, the lifting cord 9 is inserted into the insertion hole 16 of the repair slat 15, and the lifting cord 9 is also inserted at the lower position.
is inserted into the insertion hole 13 of the fixture 11, and the rest is the same as the fixture of the previous embodiment. In addition to the effects of the above embodiment, this fixture 11 can reliably support the lifting cord 9 in the slat 15 and the insertion hole 13 of the fixture 11.
By hanging the ladder cord 10 in the recesses 6 and 14 on both sides of the ladder cord 10, it is possible to prevent the ladder cord 10 from shifting with respect to the fixture 11. Further, since the insertion hole 13 of this repair slat is inserted into the slat edge through the notch 17, the slat is less likely to break in the longitudinal direction than the repair slat 7 of the previous embodiment.

Next, we will explain the third embodiment that embodies this idea in the fourth embodiment.
To explain according to the figure, the fixture 18 of this embodiment
The inner parts of the upper piece 3 and the lower piece 4 are connected by a connecting part 19. The slat 7 attached to the fixture 18 is formed with an insertion hole 20 having a width that can fit into both sides of the connecting portions 19.

When the insertion hole 20 of the slat 7 is fitted to both sides of the connecting part 19 in the above-mentioned fixture 18, and the edge of the slat 7 is engaged with the locking claw 5,
The slat 7 is supported by the fixture 18 so as not to be movable in its longitudinal direction. Therefore, in addition to the effects of the first embodiment, the fixture 18 of this embodiment can support the slat 7 immovably in its longitudinal direction and prevent the slat 7 from shifting with respect to the fixture 18. In addition, the mounting tool 1 for the slat 7
This has the effect that the mounting position of 8 can be clearly defined.

Effects of the invention As detailed above, the fixtures 1, 11, 18 according to this invention can easily attach and detach the repair slats 7, 15, can be used over and over again, and can be used for lifting cords. Repair slats 7, 1 with notches for insertion
It exhibits an excellent effect of completely supplementing the strength against bending and torsion of 5.
