Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a device for attaching a roll blind screen to a roll pipe.

[Prior art] If the upper end of a roll blind screen is directly glued to the roll pipe, it cannot be replaced, but if it is glued to a locking plate and the locking plate is removably fixed to the roll blind, the screen can be easily attached to the roll pipe depending on the season. It can be replaced accordingly. The conventional replaceable screen mounting device is the Utility Model Publication No. 53-102824.
As disclosed in No. 1, the tip of the screen is glued to a locking plate that is wider than the width of the groove opening in a groove with a trapezoidal cross section provided in a roll pipe, and the screen is bent so as to wrap around the locking plate. The screen was fixed to the roll pipe by inserting the screen from the end or circumferential surface of the roll pipe.

[Problems to be solved by the invention] However, it is not easy to glue the tip of a wide screen to a narrow locking plate.
In particular, adhering the locking plate perpendicularly to the longitudinal direction of the screen required skill. Also, when inserting the locking plate with the screen attached into the groove of the roll pipe, the tip of the screen must be bent so as to wrap around it, but if the screen is rigid and difficult to bend, it is difficult to insert the locking plate into the groove. The effect was quite troublesome.

The present invention was made to solve these problems, and its purpose is to create a device that can be easily fixed to a roll pipe, whether it is a wide screen or a rigid and difficult-to-bend screen. It is about providing.

[Means for Solving the Problems] In order to achieve the above object, the feature of the present invention is that the bottom width of the protrusion fitted into the roll pipe mounting groove of the screen mounting member is wider than the opening width of the roll pipe mounting groove; The width of the peripheral surface of the screen mounting member to which the screen is bonded is at least twice the width of the bottom of the roll pipe mounting groove. It is desirable that the screen attachment part be made of highly elastic synthetic resin, and that the bottom of the protrusion be split into two.

[Operation] Since the screen adhesive surface of the screen mounting member of the present invention does not enter the mounting groove of the roll pipe, the screen can be glued after the protrusion of the screen mounting member is inserted into the mounting groove of the roll pipe. . Further, since the bonding surface of the screen is relatively wide, bonding is easy, and the longitudinal direction of the screen can be bonded at right angles to the screen mounting member without any skill. If the screen mounting member is made of a highly elastic synthetic resin material and the bottom of the protrusion is split into two, it can be pushed in or pried up from the end without having to go in and out of the mounting groove from the end of the roll pipe. This allows it to be attached and detached from the circumferential surface of the roll pipe.

[Effects] As mentioned above, the device of the present invention differs from the conventional device in which the tip of the screen is glued to a locking plate, bent to wrap it around, and then inserted into the installation groove of the roll pipe. There is no need to insert the screen into the mounting groove of the roll pipe; the tip of the screen is glued to the peripheral surface of the mounting member along the circumference of the roll pipe, and only the mounting member is fitted into the mounting groove, so the screen can be wide. Even if the screen is rigid and difficult to bend, it has the excellent effect of being able to fix the screen to the roll pipe extremely easily. The circumferential width of the peripheral surface of the screen mounting member to which the screen is attached is more than twice the bottom width of the mounting groove, so compared to a conventional locking plate whose width is only about the same as the bottom width of the mounting groove, the screen Adhesion work is extremely easy and has the advantage that no skill is required. Furthermore, the screen mounting member can be attached to and removed from the roll pipe mounting groove from the circumferential surface as well as from the end surface, which is an effect not found in conventional devices.

[Example] The apparatus of the present invention will be described based on an example shown in the drawings. As shown in FIG. 1, the roll pipe 10 of the roll blind has a mounting groove 11 with a trapezoidal cross section.
is provided, and the protrusion 21 of the screen mounting member 20 fits into the groove. The peripheral surface part 22 of the screen mounting member 20 is along the outer peripheral surface of the roll pipe 10,
A screen 30 is glued to the surface. The width of the peripheral surface portion 22 is wide, at least twice the width of the bottom of the mounting groove 11. Since the bottom width of the protrusion 21 is wider than the mouth groove of the attachment groove 11, the protrusion 21 does not come out of the attachment groove 11 in the radial direction. The protrusion 21 is in the mounting groove 1
1 from the end face of the roll pipe 10, and the screen 30 is adhered to the outer surface of the peripheral surface portion 22 of the screen mounting member 20 after insertion via a double-sided adhesive tape 31. Screens are usually replaced together with the screen mounting members.

As shown in FIG. 2, the screen mounting member 20
If the screen mounting member is made of highly elastic synthetic resin and the bottom width of the protrusion 21 is made slightly wider than the opening width of the mounting groove 11, the screen mounting member can be removed by prying up the peripheral surface from the end using a screwdriver or the like. 20 can be removed from the mounting groove 11.

As shown in FIG. 3, the screen mounting member 20
By forming the protrusion 21 in half, the screen mounting member can be inserted into and removed from the mounting groove directly from the circumferential surface, not from the end face of the roll pipe, not only when removing it from the mounting groove but also when fitting it into the mounting groove. can.

As described above, the device of the present invention not only allows the screen mounting member to be easily attached to and removed from the roll pipe, but also allows the screen to be bonded to the screen mounting member easily and accurately.

[Brief explanation of the drawing]

Fig. 1 is an end view of essential parts of a roll blind equipped with a device according to an embodiment of the present invention, Fig. 2 is an end view showing a state in which the screen mounting member is removed from the roll pipe, and Fig. 3 is an end view of another embodiment of the roll blind. In the figure, reference numeral 10 is a roll pipe, 11 is a mounting groove, 20 is a screen mounting member, 21 is a protrusion, and 22 is a peripheral surface.
