Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a device for detachably attaching a screen to a roll pipe via an interlocking piece such as a fastener.

[Prior Art] The inventor of the present application made a screen into a roll pipe by fixing one of two support pieces connected through mutually connecting articulators such as fasteners to a roll pipe and the other to the upper edge of the screen. Proposal to detachably attach the
107890). This proposal has made it extremely easy to replace and wash screens to suit the season and atmosphere.

[Problems to be Solved by the Invention] When the supporting piece on the roll pipe side and the supporting piece on the screen side are connected with an oven-type slide fastener, and the fastener slider is removed from the fastener, if the screen is roughly pulled diagonally, the fastener will break. There was a risk that the connection would come off from the end. Also, depending on the fastener, it was not possible to use the screen by turning over the screen, which had different colors and patterns on the front and back sides.

The present invention was made to solve these problems, and its purpose is to provide a device for attaching and detaching a screen to and from a roll pipe via a fastener, which prevents the fastener from coming off even if the screen is pulled diagonally. Another object of the present invention is to provide a device that allows fastener connection even when the screen is turned inside out.

[Means for Solving the Problems] In order to achieve the above object, the features of the present invention include the following:
As shown in FIG. 1, one of the two support pieces 21 and 22 is fixed to the roll pipe 10 and the other to the upper end of the screen 30, and the two support pieces 21 and 22 are connected to each other via a fastener slider. In a roll blind screen attachment/detachment device in which articulators 20a and 20b are arranged in a row,
One of the articulators 20a and 20b is formed so that it can be connected even if it is turned inside out, and the fixing portion between the roll pipe IO and each support piece 21, 22 of the screen 30 is designed to be inside the joining range of the articulator of the fastener 20. However, the fastener slider 19 can be separated from the fastener 20. In order to facilitate attachment of the fastener slider to the articulator, it is desirable to cut off the protruding parts of the articulators 20a' and 20b' at both ends.

[Function] Align the ends of the articulator 20a of the support piece 21 on the roll pipe side and the articulator 20b of the support piece 21 on the screen side and put them into the fastener slider 19, then insert the articulator 20a with the fastener sliders arranged in a row, When slid along 20b, the articulators 20a, 20b are joined to each other, so that the two support pieces 21, 22 are connected and the screen 30 is attached to the roll pipe IO. Since the articulator of the present invention connects to each other even when one side is turned upside down, the screen can be attached with the front and back sides reversed.

Even if you pull the screen roughly diagonally, both ends of the joint range of the articulator are located outside of both ends of the fixed part between the roll pipe of the support piece and the screen, so the beginning and end of the mutual joint of the articulator are Since the force trying to separate is smaller than the force trying to separate the inner articulator, there is no risk that the articulator will come off one by one from the end.

[Example] The apparatus of the present invention will be described in detail based on an example shown in the drawings. As shown in FIG. 1, a double-sided adhesive tape 12 is pasted on one side of the groove 14 of the roll pipe 10 of the roll blind, but the double-sided adhesive tape is not pasted on a portion of a certain length A from both ends of the roll pipe 10. . Double-sided tape 1
2, one support piece 21 to which one articulator 20a of the fastener 20 is attached can be stretched over. The length of the support piece 21 is the same as the length of the roll pipe 1O, but the length of the double-sided adhesive tape 12, which serves as the fixed portion between the roll pipe IO and the support piece 21, is shorter by 2A than the length of the roll pipe 1o.

The other articulator 20b of the fastener 20 is the other support piece 22
and the tape is sewn to the upper edge of the screen 30. The support piece 22 and the screen 30 also have the same length as the roll pipe 10. At both ends of the support piece 22 there are provided parts that cannot be sewn onto the screen 30 of a certain length A with the sewing thread 13, so that the screen 30 and the support piece 2
The length of the fixed part 2 is shorter than the roll pipe IO by a length of 2A.

Since the fastener 20 is located on the groove 14, the fastener 20
There is no risk that the winding shape of the screen 30 will be distorted due to the projecting. The overall length of the fastener 20 is the same as both support pieces 21.22, but the articulator 20 within a length B from both ends thereof
The protrusions a' and 20b' that connect with each other are cut off. The length B of both ends is set shorter than the length A of the unattached portions at both ends of each supporting piece 21, 22 of the roll pipe 10 and the screen 30.

The articulators 20a and 20b of the fastener 20 in FIG.
It is also possible to use a fastener 20 in which synthetic resin monofilaments are woven into the articulators 20a and 20b. In this case as well, the protrusions of the articulators 20a' and 20b' at both ends are removed. Furthermore, although not shown, a fastener in which a metal articulator is sewn onto a tape can also be used. Both fasteners 20 have articulators 20a and 20b.
are of a shape that connects to each other even if one side is turned inside out.

Next, attachment and detachment of the screen 30 will be explained.

As shown in Figure 3, the fastener slider! 9 is fixed to the tongue portion 41 of the cap 42 on one side of the weight par 40 either directly or via a chain, so there is no risk of the fastener slider 19 being removed from the fastener 20 and being lost.

Therefore, when installing the screen 30, first remove the cap 42 from the weight par 40 and take out the fastener slider 19. Next, as shown in FIG. 4, the articulator 20a of the coal pipe side support piece 21 and the articulator 20b of the screen side support piece 22 are brought into contact with each other, and the fastener slider 19 is fitted from one end in the direction of the arrow. 20
Since the protrusions of the articulators 20a' and 20b' at the ends of the articulators 20a' and 20b' have been cut off, the fastener slider 19 can easily fit into the articulators. Next, move the fastener slider 19 to the articulator 2.
When sliding along the rows of 0a and 20b, the articulator 20a,
20b is phase! f, and the screen 30 is removed and attached to the roll pipe 10. Since the fastener slider 19 comes out from the other end and is separated from the fastener 20, the cap 42 is moved by weight/<-40 as shown in FIG.
and store the fastener slider 18 therein.

When removing the screen 30, as shown in FIG.
When you pull the end of the support piece 22 on the screen 30 side in the direction of the arrow, the connection between the articulator 20a of the roll pipe IO side support piece 21 and the articulator 20b of the screen 30 side support piece 22 will come apart sequentially from the end, so don't bother storing it. There is no need to take out the fastener slider and insert it into the fastener.

Both ends of the connection range of the articulators 20a and 20b of the fastener 20 are areas connecting both ends of the support piece 21 and the fixed part of the roll pipe 10 with the double-sided adhesive tape, and both ends of the support piece 22 and the sewn part of the screen 30 with the sewing thread. Since it is located on the outside, no matter how you pull the screen 30, the fastener 20
The force acting on the articulators at both ends of the joining range is smaller than the force acting on the inner articulator. Therefore, screen 3
There is no risk that the fastener 20 will come off one by one from the end even if the 0 is pulled roughly.

In the device of the embodiment, in order to make it easier to fit the fastener slider into the articulator, the protruding parts of the articulator at both ends of the fastener were cut off, so that the joining range of the fastener was made shorter than the entire length. However, the protruding portions of the articulator at both ends of the fastener do not necessarily need to be removed, and the overall length of the fastener and the joining range may be made the same.

[Effects of the Invention] As described above, since the articulators of the fasteners of the device of the present invention are connected even if the front and back sides are reversed, the screen can be easily turned over. In addition, both ends of the support piece that connects the screen to the roll pipe and the part that is fixed to the screen are inside the connection range of the fastener, so even if you pull the screen roughly into a bubble, it will not touch both ends of the fastener. Since the applied force is smaller than the inwardly acting force, there is no risk of the fasteners coming off one after the other.
