JPH1146972A - Structure for fitting screen to head rail in roll-up curtain device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To fit a screen for a roll-up curtain device to a head rail without using a hook-and-loop fastener. SOLUTION: A side edge part in a width direction of a relatively hard belt- like member 3 is connected integrally with an upper end edge part 21 of a screen 2 by e.g. sewing a front surface part 11 or a rear surface part or a bottom surface part 12 under the both surface parts of a head rail 1 is slightly protruded outwardly, and then extended upwardly to form a screen hanging part 13. A fitting groove 14 having an inner width equal to or larger than the thickness of the belt-like member, and a depth larger than the length in a width direction of an unconnected part 32 not connected with the upper end edge part of the screen of the belt-like member is formed between the screen hanging part 13 and the front surface part 11 or the rear surface part or the both surface parts. Then, the unconnected part of the belt-like member is inserted into the fitting groove 14 to fit the screen 2 to the head rail 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for attaching a screen of a lift-up curtain device to a head rail.

[0002]

2. Description of the Related Art A screen hanging from a head rail of a lift-up curtain device has an upper edge portion attached to the front or rear surface of the head rail via a detachable joining member called "magic tape" (trade name).

[0003]

The attachment of the screen to the head rail by the magic tape has the following problems. 1. Since the magic tape is too easy to attach, it is rather difficult to attach the screen to a normal position, and it is often necessary to reattach the screen. 2. The cost is relatively high due to the material cost of the magic tape and the man-hours required to glue or sew the male and female to the head rail and the upper edge of the screen, respectively.

The present invention has been made to solve these problems, and an object thereof is to attach an upper edge of a screen to a head rail without using a velcro tape.

[0005]

In order to achieve the above-mentioned object, a means adopted by the present invention is to sew and bond one side edge in the width direction of a relatively hard belt-like member to an upper edge of a screen. And a mounting groove is provided on the front and / or rear face of the head rail, into which a non-joined portion of the belt-like member connected to the screen can be inserted. The inner width of the mounting groove is set equal to or larger than the thickness of the belt-shaped member, and the depth is set to be slightly larger than the width of the non-joined portion of the belt-shaped member.

The screen is attached to the head rail by inserting the non-joined portion of the belt-like member integrally joined with the screen into the attachment groove. Since the inserted belt-like member is relatively hard, there is no danger that the belt will be U-turned and fall out of the mounting groove even if the screen is pulled downward. The belt-shaped member inserted into the mounting groove easily comes off upward. Therefore, it is extremely easy to attach and detach the screen to and from the head rail.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described based on a first embodiment shown in the drawings. As shown in FIG.
The bottom portion 12 of the front portion 11 slightly protrudes outward, and then bends upward to form the screen hanging portion 13. A mounting groove 14 for mounting a screen is formed between the screen hanging portion 13 and the front portion 11.

[0008] One lateral edge 31 of the belt-shaped member 3 in the width direction is integrally joined to the upper edge 21 of the screen 2 by sewing or bonding. The remaining non-coupling portion 32 of the belt-shaped member 3 that has not been coupled to the screen 2 is inserted into the mounting groove 14, and the screen 2 is hung down in front of the head rail 1.
Since the inner width of the mounting groove 14 is slightly larger than the thickness of the belt-shaped member 3 and the depth is slightly larger than the width of the non-coupling portion 32 of the belt-shaped member 3, the non-coupling portion 32 is deep and almost entirely the mounting groove 14. go inside. Since the belt-shaped member 3 is made of a heavy-weight fabric or a relatively hard material made of rubber or synthetic resin, even if the non-coupling portion 32 is pulled down along the outer surface of the screen hooking portion 13 together with the screen, Non-coupling part 32
Does not come out of the mounting groove 14 by making a U-turn.

The attachment or detachment of the screen 2 to or from the head rail 1 is as simple as inserting or pulling out the non-joined portion 32 of the integrally connected belt-like member 3 into the attachment groove 14 of the head rail 1. The work is extremely easy, and when the non-coupling part 32 is inserted into the mounting groove 14 to the limit,
The screen 2 is naturally mounted in a normal position.

Since the velcro is not used for attaching the screen 2 to the head rail 1, the cost of the velcro and the number of steps for attaching the velcro to both the screen and the head rail are reduced, and the cost is reduced as a whole.

[0011]

Another embodiment of the present invention will be described with reference to the drawings. The head rail 1a of FIG.
Slightly protrudes outward, and then bends upwards to form a screen hooking portion 17, which has a screen hooking portion 17 and a rear portion 1.
5, the mounting groove 18 is formed. The screen 2 attached to the head rail 1 by the attachment grooves 18 is the screen 2 inverted from that of the first embodiment. This screen 2
The relationship between and the mounting groove 18 is the same as in the first embodiment.

The head rail 1b shown in FIG. 3 has a front part 11 and a bottom part 12, 16 of a back part 15 slightly projecting outward, respectively, and then bends upward to form screen hanging parts 13, 17. The relationship between the two mounting grooves 14 and 18 formed by the screen hanging portions 13 and 17 and the two screens 2 and 2 mounted by the mounting grooves is exactly the same as that of the first and second embodiments.

[0013]

As described above, the present invention relates to a belt-like member having a mounting groove provided on the front, back, or both sides of a head rail, and an upper side edge integrally connected to an upper edge of the screen in the mounting groove. The structure is such that the screen is attached to the head rail by inserting the non-joined part, and the magic tape is not used as in the past, so the material cost of the magic tape and the man-hour for bonding the magic tape to the screen and the head rail are reduced, as a result In addition to the cost reduction, the screen can be normally installed only by inserting the belt-shaped member into the mounting groove, so that an excellent effect that the mounting work becomes extremely easy is achieved.

[Claims] A relatively hard belt-like member (3) is integrally joined to one end in the width direction of the screen-like member (2) by sewing or the like at the upper end edge (21) of the screen (2) to form a head rail (1, 2). 1a, 1
The bottom (12, 16) below the front (11) or back (15) or both sides of b) is slightly protruded outward, and then extended upward to form a screen hook (13,
17), wherein the inner width is equal to or greater than the thickness of the belt-shaped member, and the depth is between the screen hanging portion and the front portion or the back portion or both surface portions thereof. Attachment grooves (14, 18) larger than the width in the width direction of the non-joined portions (32) not joined to the upper edge of the screen of the member are formed, and the unjoined portions of the belt-like member are inserted into the attachment grooves. Wherein the screen is attached to the head rail in the lift-up curtain device.
