Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a mounting device for removably fixing a screen to a screen winding tube of a roll blind.

[Prior Art] Various types of removable joining members are used to removably attach a screen to a winding tube of a roll blind. Synthetic resin clothing joining piece (trademark Velcro), which is made by planting many synthetic resin needles on a piece of cloth, is also a removable joining member, but it is thicker than fasteners or other uneven joining members, so it cannot be smooth or smooth. When the screen was attached to the circumferential surface of the winding cylinder, there was a problem that the screen was rolled up in an irregular manner.

[Problems to be solved by the invention] The invention was made to solve the above problems, and its purpose is to attach a screen to the winding tube through a synthetic resin clothing joint. Another object of the present invention is to provide a mounting device that prevents the screen from being rolled up in an irregular manner.

[Means for Solving the Problem] In order to achieve the above object, the feature of the present invention is to form a mounting groove extending in the axial direction on the circumferential surface of the winding tube, and to attach a synthetic resin clothing to the groove. One piece of the material is glued and the other piece is attached to the upper edge of the screen.

The mounting groove can be cut directly into the circumferential surface of the roll pipe, but it can also be formed by fitting a split sleeve onto the roll pipe.

[Function] When the depth of the mounting groove formed on the circumferential surface of the roll pipe is made approximately equal to the thickness of the synthetic resin clothing joining piece, one side of the synthetic resin clothing joining piece can be glued to the bottom of the groove. Even if the other side attached to the upper edge of the screen is polymerized, the outer circumference of the synthetic resin clothing joining member almost matches the circumference of the roll pipe, so even if the screen is rolled, it will not be distorted. It never winds up.

[Example] The screen mounting device of the present invention will be described based on an example shown in the drawings. As shown in FIG. 1, a mounting groove 12 extending in the axial direction is cut on the circumferential surface of the roll pipe 11, which is the winding tube 10 itself of the roll blind, and as shown in FIG. One side 20a of the synthetic resin clothing joining piece 20 is glued onto the bottom surface of the groove 12. As shown in FIG. 3, the other synthetic resin clothing joining piece 20b is glued or sewn to the upper edge of the screen 30.

As shown in FIG. 1, the other 20b attached to the screen 30 is overlapped and bonded to one side 20a of the synthetic resin clothing bonding piece glued to the roll pipe 11, and the screen 30 is fixed to the winding cylinder 10. do. Since the outer circumferential surface of the synthetic resin clothing joining piece 20 substantially coincides with the outer circumferential surface of the winding tube 10, the screen 3
0 is wound onto the winding tube without being distorted as shown by the chain line. As shown in FIG.
It is also possible to fit the split sleeve 15 into the winding cylinder 10 and form the mounting groove 12 between the slit of the split sleeve 15 and the circumferential surface of the roll pipe 11 between the slits. In this case, in order to prevent the screen 30 from being rolled up in an irregular manner, the thickness of the split sleeve 15 is made approximately the same as the thickness of the synthetic resin clothing joining piece 20.

As shown in FIG. 5, a convex portion 15a is formed in a part of the split sleeve 15, and a concave portion 11a that engages with the convex portion is carved in the roll pipe 11.
Split sleeve 1 so as to engage recess 11a with
5 can be fitted into the roll pipe 11 to form the winding tube 10 provided with the mounting groove 12. In this way, the split sleeve 15 is not only fixed in the circumferential direction, but also the recess 11a determines the position of the mounting groove 12, so the split sleeve 15 is fixed to the roll pipe 11.
One of the synthetic resin clothing joining pieces 20 can be glued to the roll pipe before fitting.

[Effects of the invention] As mentioned above, in the roll blind of the present invention, the screen is fixed to the winding tube through the synthetic resin clothing joint piece, so it is extremely easy to attach and remove the screen, and the outer periphery of the joint piece Since the screen matches the circumferential surface of the winding tube, it has the excellent effect of preventing the screen from being rolled up in an irregular manner.
