Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a profile roll screen having a non-rectangular screen suitable for use in a profile window or the like.
[0002]
[Prior art]
Conventionally, in this type of deformed roll screen, a winding pipe, a non-rectangular screen whose one end is connected to the winding pipe so as to be windable, and the other end of the screen are attached non-parallel to the winding pipe. In general, an aluminum mold or the like is used as the weight member in order to maintain the shape of the end portion of the screen.
[0003]
[Problems to be solved by the invention]
However, in such a conventional roll screen, when the screen is wound around the take-up pipe, the end of the weight member, which is originally close to the take-up pipe, comes into contact with the take-up pipe. It can no longer be wound. Therefore, even when the screen is wound up to the maximum extent, a part of the screen remains exposed, and there is a problem that it does not look good.
[0004]
The present invention has been made to solve the above-mentioned problems, and even if it is a deformed roll screen, it is possible to completely wind the screen around the take-up pipe and improve the appearance. The purpose is to provide.
[0005]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the invention according to claim 1 of the present invention includes a winding pipe, a non-rectangular screen having one end removably connected to the winding pipe, and the other end of the screen. A weight member attached non-parallel to the take-up pipe on the screen, a plurality of wires connected to the other end of the screen with their one ends spaced apart from each other, and the other end of the wire connected so that it can be wound and unwound A roll screen having a wire take-up device,
The weight member is elastically deformable,
The weight member can be simultaneously wound around a winding pipe together with some wires and a screen.
[0006]
Even if the end of the weight member that is close to the take-up pipe comes into contact with the take-up pipe after the screen is wound on the take-up pipe, the weight member is taken up with the screen from the contacted end. Rolled up. In this way, the entire screen can be completely wound.
[0007]
As the weight member, a thin plate having a self-shape holding force can be used. For example, a blind slat can be used. When the screen is pulled out from the take-up pipe, the weight member returns to the original shape again by the elastic restoring force and self-shape holding force of the weight member, and holds the shape of the other end of the screen.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 5 are views showing an embodiment of a deformed roll screen according to the present invention.
[0009]
The deformed roll screen 10 is attached to a trapezoidal deformed window W, and a winding pipe 12 rotatably supported by a bracket 11 at one end side of the deformed window W, and a winding pipe 12. One end of the screen 14 is connected so as to be wound. The winding pipe 12 incorporates a biasing means including a coil spring and is always biased in the screen winding direction. The screen 14 has a trapezoidal shape as a whole, and a weight member 16 is attached to the other end side of the screen 14 which is not parallel to the winding pipe 12. The weight member 16 is formed of a thin plate having a self-shape holding force, and is integrally attached to the screen 14 by eyelets 18 and 18 as shown in FIG. The weight member 16 can not only hold the other end portion of the screen 14 in an extended state by its self-shape holding force, but can be elastically deformed, and can be wound around the winding pipe 12 as described later. It has become. Specifically, an aluminum blind slat can be used, and if it has an arc-shaped cross section having a large radius of curvature rather than a completely flat surface, such as a slat, the weight member has a rigid rigidity. Higher and preferable. In addition, the screen 14 and the weight member 16 can be coupled by other coupling means such as a double-sided adhesive tape.
[0010]
One end of a plurality of wires 20 is attached to the other end portion of the screen 14 to which the weight member 16 is attached, being appropriately separated from each other, and the other end of each wire 20 is connected to the other end side portion of the odd-shaped window W. It is connected to a wire winding device 22 provided so that it can be wound and unwound.
[0011]
The operation of the deformed roll screen 10 configured as described above will be described.
[0012]
FIG. 1 shows a state in which the wire winding device 22 has wound the wire 20 almost completely, and the screen 14 is in a fully closed state almost covering the window W. When the wire winding device 22 is driven from this state to unwind the wire 20, the winding pipe 12 rotates in the winding direction as shown in FIG. A part of the window W is exposed. Further, when the wire 20 is unwound and the final winding stage is reached, 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 and fully opened, and the window W can be completely exposed. Thus, there is no unwinding residue 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, it is not bulky even when wound on the winding pipe 12.
[0013]
On the other hand, when the wire winding device 22 is driven to wind the wire 20, the weight member 16 and the screen 14 are drawn out by the winding pipe 12 and the window W is closed. At this time, due to the elastic restoring force of the weight member 16, the weight member 16 is in a state of extending in a straight line, and the screen 14 can be sufficiently expanded.
[0014]
Durability can be imparted by using blind slats for the weight member 16, and it can be easily configured by using existing parts.
[0015]
【The invention's effect】
As described above, according to the first to third aspects of the present invention, the weight member can be wound around the winding pipe together with the screen. It can be completely wound up and can improve its appearance.
[0016]
According to the second aspect of the present invention, when the weight member is not wound on the winding pipe, the shape of the other end portion of the screen can be maintained, while being wound on the winding pipe. It is possible not to be bulky in the state of being wet.
[0017]
Further, according to the invention described in claim 3, rigidity and durability can be given by using blind slats, and it can be easily configured by using existing parts.
