Description

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

[Prior Art] A method of locking a screen to a roll pipe by attaching the end of the screen to a screen mounting piece and inserting the screen mounting piece into a screen mounting groove carved in the roll pipe is as follows:
It is publicly known as disclosed in Utility Model Application Publication No. 53-102824.

However, in the conventional method, the end of the screen was wrapped around a screen mounting piece and inserted into the screen mounting groove of the roll pipe, so thick screens were difficult to install unless the screen mounting groove was deep. However, since roll blinds have various mechanisms installed inside the roll pipe,
It was difficult to deepen the screen mounting groove. Furthermore, when the screen becomes thicker, the attachment and detachment of the screen mounting piece is limited to the axial direction, and there is a problem in that it is difficult to attach and detach the screen attachment piece in the radial direction.

[Problems to be solved by the invention] The invention was made to solve the above problems, and its purpose is to easily attach and detach the screen without inserting the screen into the screen installation groove of the roll pipe. Our goal is to provide screen mounting pieces.

[Means for Solving the Problems] In order to achieve the above object, the feature of the present invention is to attach a screen mounting piece made of a highly elastic synthetic resin to a base wider than the opening width of the screen mounting groove of the roll pipe. and a screen attachment portion exposed from the base portion to the opening of the screen attachment groove, and the screen end portion is fixed to the screen attachment portion.

A step may be provided in the rooting portion to fit into the opening edge of the screen rooting groove. The end of the screen is attached directly to the upper surface of the screen attachment part exposed at the opening of the screen attachment groove, or is attached to the tongue piece which is attached to the upper surface of the screen attachment part and extends in the circumferential direction.

[Function] The screen attachment piece of the present invention has a total length that is approximately equal to the total length of the roll pipe, and can be inserted into the screen attachment groove in the axial direction from the end surface of the roll pipe. The rooting part has a flat or chevron-shaped cross section and is made of highly elastic synthetic resin, so when it is pinched in the width direction with fingers, the part bends into a V shape and the width becomes narrower than the opening width of the screen mounting groove. Therefore, the screen mounting piece can be inserted into the screen mounting groove from the radial direction by sequentially pinching and inserting the root portion from the axial end of the screen mounting piece into the screen mounting groove.

Before inserting the screen mounting piece into the screen mounting groove, attach the edge of the screen to the screen attachment part of the screen mounting piece with adhesive, or
Or sew it on with sewing thread. The thickness of the screen attachment area is thin and the edges of the screen can be easily sewn. If a protrusion or a groove is provided on the upper surface of the screen attachment part to serve as a reference for attachment, the end of the screen can be attached to the screen attachment piece accurately. The screen attachment piece to which the screen is attached is inserted into the screen attachment groove of the roll pipe to lock the screen to the roll pipe, but unlike the conventional method, the screen itself does not fit into the screen attachment groove.

[Effects of the invention] As mentioned above, the screen mounting piece of the present invention allows the screen to be mounted on the roll pipe without inserting the screen end into the roll pipe's screen mounting groove, so the screen mounting groove on the roll pipe is shallow. It has an excellent effect not found in conventional methods, in that even thick screens can be attached.

For roll blinds that house the mechanism inside, there is a great advantage that the screen mounting groove of the roll pipe is shallow.Also, even when a thick screen is attached, the screen mounting groove of the roll pipe can be gradually tightened from one end in the axial direction. By attaching and detaching the screen, the screen can be attached and detached in the radial direction. Therefore, when using the screen mounting piece of the present invention,
Regardless of the thickness of the screen, it is extremely easy to replace the screen to suit the season or atmosphere, and to wash it when it gets dirty.

[Example] The screen mounting piece of the present invention will be explained based on an example shown in the drawings.

As shown in FIG. 1, the roll pipe 10 of the roll blind is provided with a screen mounting groove 12 having a convex cross-section passing through in the axial direction on the circumferential surface, and a screen mounting piece made of highly elastic synthetic resin of the present invention is inserted into the groove. 20 is fitted. Screen mounting piece 20
The screen attaching part 22 is attached to the screen attaching groove 1.
It fits into the opening of 2, and the screen 3 is placed on the top surface.
0 ends are sewn with sewing thread 32. The width of the rooting part 21 of the screen attachment piece 20 is equal to or slightly smaller than the width of the screen attachment groove 12, but the width of the screen attachment part 22 is the same as the width of the opening of the screen attachment groove 12, When the attachment piece 20 is inserted into the screen attachment groove 12, its upper surface matches the circumferential surface of the roll pipe 10.

As shown in FIG.
It is desirable to form the screen attachment part 22 into a rounded inverted U-shape, and to provide a small protrusion 24 extending in the axial direction on the upper surface of the screen attachment part 22 to serve as a reference when gluing or sewing the screen end. Since the screen attachment part 22 is relatively thin and can pass a sewing needle through it, it is not necessarily necessary to provide a thread hole.

As shown in FIG.
The screen attaching portion 22 may be formed into a rectangular shape, and the upper surface thereof may be provided with grooves 26 that serve as a reference for attaching the end of the screen, and thread holes 28 for sewing may be provided.

As shown in FIG. 4, the screen mounting piece 20
A thin tongue piece 25 extending in the circumferential direction may be provided on the screen attachment part 22 of the screen attachment part 22, and the end of the screen 30 may be adhered or sewn to the tongue piece. By forming a protrusion 24 extending in the axial direction on the upper surface of the tongue piece 25 and abutting the upper edge of the screen 30 against the protrusion, the screen can be attached accurately.

After gluing or sewing the end of the screen to the upper surface of the screen attachment part 22 of the screen attachment piece 20, the screen attachment piece 20 is attached to the roll pipe 10.
into the screen mounting groove 12 of the screen. The cross section of the screen mounting piece 20 corresponds to the screen mounting groove 10.
Since the end of the screen 30 is not inserted into the screen mounting groove 12, it goes without saying that the screen mounting piece 20 can be easily attached and detached from the end surface of the roll pipe 10 in the axial direction. .

As shown in FIG. 5, the screen mounting piece 20 of the present invention is relatively thin and highly elastic, so when it is pinched with fingers in the width direction, it bends into a V shape and the width opens the screen mounting groove 12 of the roll pipe 10. narrower than the width of the part. Therefore, even if a thick screen 30 is attached, the screen mounting piece 20 can be mounted in the radial direction by sequentially pinching the screen mounting piece 20 from the axial end with fingers and inserting it into the screen mounting groove. It can be inserted into the groove 12. Conversely, if the end of the screen attachment piece is pried up and removed from the screen attachment groove with a screwdriver, the remaining pieces can be sequentially taken out from the screen attachment groove in the radial direction.

Although the screen mounting piece of the above embodiment has a convex cross-section, the cross-sectional shape is not limited to the convex shape, and as shown in FIG. 6, the screen mounting piece 2
The rooting part 21 of 0 may be formed into a flat plate shape with a medium height, and the screen attachment part 22 as a tongue extending from the medium height part along the outer peripheral surface of the roll pipe 10 may be provided. The insertion of the screen mounting piece in FIG. 6 into the screen mounting groove is exactly the same as that in FIG.

As shown in FIG. 7, the screen mounting piece 20
The rooting portion 21 may be formed in a U-shape in cross section equal to the opening width between the screen mounting grooves 12, and steps 27 may be provided on both sides thereof, and a tongue-shaped screen attachment portion 22 may be provided on the upper surface of the step 27. The screen mounting piece of this embodiment is directly pushed into the screen mounting groove as shown by the arrow. As shown in FIG. 8, the pushed-in screen attachment piece 20 is fixed to the opening edge of the screen attachment groove 12 by the steps 27 on both sides, and the screen attachment part 22 extends along the outer peripheral surface of the roll pipe 10. . The end portion of the screen is glued or sewn to this screen attachment portion.
