Abstract

PROBLEM TO BE SOLVED: To provide a specially shaped roll screen which can be completely wound up on a take-up pipe, to thereby enhance the appearance thereof. SOLUTION: There is provided a non-rectangular screen 14 which had one end thereof connected to a take-up pipe 12 so as to be wound up thereon, and the other end thereof attached to a sheetlike weight member 16. The other end of the screen 14 can be elastically deformed, and is arranged not in parallel with the take-up pipe 12. When the screen 14 is in a final wound-up stage, the weight member 16 is wound up on the take-up pipe 12 together with the screen 14, to thereby completely wind up the screen 14.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a modified roll screen having a non-rectangular screen suitable for use in a modified window or the like.

[0002]

2. Description of the Related Art Conventionally, in a roll screen of this type, a winding pipe, a non-rectangular screen whose one end is rotatably connected to the winding pipe, and a winding pipe at the other end of the screen. And a weight member mounted in a non-parallel manner, and as the weight member, an aluminum mold material or the like is generally used to maintain the shape of the end of the screen.

[0003]

However, in such a conventional roll screen, when the screen is wound around a winding pipe, one end of the weight member, which is originally closer to the winding pipe, is wound. Once in contact with the pipe, the screen can no longer be wound. For this reason, even when the screen is wound to the maximum, a part of the screen remains exposed, and there is a problem that the appearance is poor.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and even in the case of an irregularly shaped roll screen, the screen can be completely wound around a winding pipe and the appearance can be improved. Its purpose is to provide a mold roll screen.

[0005]

In order to achieve the above-mentioned object, the invention according to claim 1 of the present invention comprises a winding pipe and a non-winding pipe having one end rotatably connected to the winding pipe. A roll screen having a rectangular screen and a weight member attached non-parallel to the winding pipe at the other end of the screen, wherein the weight member is elastically deformable, and the weight member is provided together with the screen. It is characterized in that it can be wound around a winding pipe.

The screen is wound around a winding pipe,
Even if the end of the weight member originally closer to the winding pipe contacts the winding pipe, the weight member is wound onto the winding pipe together with the screen from the contacted end. Thus, the entire screen can be completely wound.

As the weight member, a thin plate having a self-shape retaining force can be used. For example, a blind slat can be used. When the screen is pulled out from the winding pipe, the weight member returns to its original shape again by the elastic restoring force and self-shape holding force of the weight member, and retains the shape of the other end of the screen.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 5 are views showing an embodiment of a modified roll screen according to the present invention.

The deformed roll screen 10 is attached to a trapezoidal shaped window W, and a winding pipe 12 rotatably supported by a bracket 11 at one end of the shaped window W; A screen 14 has one end connected to the pipe 12 so as to be windable. The take-up pipe 12 has a built-in biasing means formed of a coil spring, and is constantly biased in the screen winding direction. The screen 14 has a trapezoidal shape as a whole.
A weight member 16 is attached to the other end of the screen 14 that is not parallel to the screen 2. The weight member 16 is formed of a thin plate having a self-shape retaining force, and is integrally attached to the screen 14 by eyelets 18 as shown in FIG. The weight member 16 can not only hold the other end of the screen 14 in an extended state, but also elastically deform, and can be wound on the winding pipe 12 as described later. Has become. Specifically, a blind slat made of aluminum can be used.If the slat has a circular cross section having a large radius of curvature instead of a completely flat surface, the rigidity of the weight member can be reduced. Higher and preferred. Also,
The present invention is not limited to this example, and the screen 14 and the weight member 16 can be connected by other connecting means such as a double-sided adhesive tape.

At the other end of the screen 14 to which the weight member 16 is attached, one ends of a plurality of wires 20 are attached at appropriate intervals, and the other end of each wire 20 is connected to the other end of the odd-shaped window W. It is wound and unwound to a wire winding device 22 provided on the side.

The operation of the irregularly shaped roll screen 10 configured as described above will be described.

FIG. 1 shows that the wire winding device 22 is
Is almost completely wound, and the screen 14 is in a fully closed state that almost covers the window W.
In this state, the wire winding device 22 is driven to
When 0 is unwound, as shown in FIG. 2, the winding pipe 12 rotates in the winding direction, winds the screen 14, and a part of the window W is exposed. Further, when the wire 20 is unwound and the winding is completed, one end of the weight member 16 reaches the winding pipe 12 as shown in FIG. Since the weight member 16 is thin and elastically deformable and can be wound around the winding pipe 12, the weight member 16 is spirally wound around the winding pipe 12 from one end of the weight member 16 together with the screen 14. To go. In this way, as shown in FIG. 4, the screen 14 can be completely wound up to be in the fully opened state, and the window W can be completely exposed.
In this manner, there is no remaining winding of the screen 14, and the appearance in the fully opened state can be improved. If the weight member 16 has a thin plate shape, the weight member 16 does not become bulky when it is wound around the winding pipe 12.

Conversely, when the wire winding device 22 is driven to wind up the wire 20, the weight member 16 and the screen 14 are pulled out by the winding pipe 12, and the window W is closed. At this time, the weight member 16
Due to the elastic restoring force, the weight member 16 is in the original linearly extended state, and the screen 14 can be in a state of being sufficiently extended.

By using blind slats for the weight member 16, durability can be provided, and by using existing parts, the structure can be simplified.

[0015]

As described above, claims 1 to 3 are described.
According to the described invention, since the weight member can be wound around the winding pipe together with the screen, when the screen is fully opened, the odd-shaped screen can be completely wound up to the end, and the appearance is improved. Can be done.

According to the second aspect of the invention, when the weight member is not wound on the winding pipe, the shape of the other end of the screen can be maintained, while the weight member is not wound on the winding pipe. In the wound state, it can be prevented from becoming bulky.

According to the third aspect of the present invention, rigidity and durability can be imparted by using the blind slats, and the structure can be simplified by using existing parts. .
