Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window used for a daylighting window provided in a high place of a building such as a skylight.
The present invention relates to a roll-in screen, a wind-up screen such as an awning screen, and particularly to an opening / closing mechanism thereof.

[0002]

2. Description of the Related Art In recent years, there is an increasing number of cases where a skylight is provided in a building such as a house for the purpose of lighting, and the skylight of the skylight is used to obtain a ventilation function in the room. Often has a structure that can be opened and closed, such as a slide type or a rotary type. However, in the case of a skylight having an opening / closing mechanism, insects, dust, and the like may enter the room when the shoji screen is opened. Therefore, in order to prevent the invasion of such insects, there is one in which a screen door is juxtaposed at the opening of the skylight. However, when the screen door is closed, the amount of light is reduced by about 30%. Therefore, it is preferable to keep the screen door open from the viewpoint of daylighting when the shoji of the skylight is closed. Therefore, it is desired to provide such a screen door with an opening / closing mechanism. In addition to such screen doors, there is a case where an awning screen that can be opened / closed is provided in the skylight or a window at a high place on the wall to adjust the amount of light.

As a mechanism for opening and closing screens such as screens and sunscreens used for the above-mentioned skylights and the like, as disclosed in Japanese Utility Model Laid-Open No. 3-101798, a hand-holding type stopper release mechanism is used. It is conceivable to adopt the screen opening / closing mechanism that it has. However, since skylights are installed at high places, it is very difficult to open and close using the above-mentioned hand-grip type stopper lock release mechanism. It is dangerous because you need to

In view of the above problems, it is an object of the present invention to provide a retractable screen having a structure which can be easily opened and closed even when installed in a high place.

[0005]

In order to achieve the above object, the present invention is attached to an end of an opening at a high place of a building,
The screen includes a screen housing having a spring and a roll for winding the screen, and guide rails provided on both sides of the opening. The screen has an end bar at its tip.
The end bar has guide portions at both ends that slide in engagement with the guide grooves of the guide rails, and are urged outward at both end portions of the end bar. Is provided, and a stopper receiving portion is provided at the end of the guide rail opposite to the screen housing installation portion so that the stopper is automatically locked by the opening / closing operation of the screen. Attaching a member, providing an engaging means for engaging an operating rod to the rotating member, and rotating the rotating member between the rotating member and the stopper via the operating rod and the engaging means. Thus, a connection member for moving the stopper to release the locking by the stopper receiving portion is provided.

[0006]

Since the present invention has the above-mentioned structure, the end bar of the screen is closed by engaging the operating rod with the engaging means of the end bar and pulling in the closing direction from the state where the screen is open. And the stopper is automatically locked to the stopper receiving portion. Further, when the rotating member is rotated by the operating rod from the state where the screen is closed, the stoppers provided at both ends of the end bar are moved through the connecting member to be disengaged from the stopper receiving portion, and the screen is removed. The screen is automatically wound by a spring provided in the housing.

Roof tiles fixed on top (tiles not shown), 25 is a heat insulating material,
Reference numeral 26 denotes a ceiling interior finishing material, and 28 denotes an opening interior material fixed to the opening frame 27.

The roll screen unit according to the present invention is a roll screen door unit.
The roll screen door housing 1 for winding and storing the reel screen door 3 is fixed to the opening frame 27 by a fixing tool 30 such as a screw,
Similarly, the left and right guide rails 2 are fixed to the opening frame 27 by the same fixing tool 30. The roll screen door 3 is configured to be wound around the roll 1c by a coil spring 1b provided between the center shaft 1a and the roll 1c. An end bar-4 is attached to the tip of the roll screen door 3. The end bar 4 is formed by fixing end members 4c forming guide portions 4b on both sides of a main material 4a made of resin or aluminum extruded shape material. In the figure, the roll screen door 3 is pulled out from the roll 1c,
Indicates a closed state.

As shown in FIGS. 2 and 3, the end bar is
Reference numeral 4 denotes guide portions 4b at both ends which are connected to the left and right guide rails
It is slidably fitted in the guide groove 2a of the rule 2. Further, the edge member 3a made of a resin sheet fixed to the edge of the roll screen door 3 is slidably fitted in the edge member guide 2b fixed in the guide rail 2 and is attached to the end bar-4. A cushion material 33 such as rubber is provided, and the cushion material 33 is brought into contact with the opening interior material 28 in a state where the roll screen 3 is closed so that no gap is formed between the guide rail 2 and the end bar-4. ing.

Further, the end bar 4 is provided with stoppers 5 at both ends thereof, and the stoppers 5 are stopper cases 5b.
It is inserted into and retracted from the housing and is biased by the built-in spring 31 so as to project outward. On the other hand, each of the guide rails
The roll 2 is provided with a stopper receiver 10 at the end opposite to the roll screen door housing 1. Here, the housing 1 side surface of the stopper receiver 10 is formed as an inclined surface 10a, and the tip end surface of the stopper 5 opposite to the housing 1 is formed as an arc surface 5a, so that when the roll screen door 3 is closed, The arcuate surface 5a of the stopper 5 comes into contact with the inclined surface 10a, and the stopper 5 is smoothly inserted and automatically locked. The end bar-4 has a hole 4d at substantially the center thereof.
The rotating member 6 is fitted and attached to d, and the hook-shaped engaging means 7 is attached to the lower surface side of the rotating member 6 such as a screw 1 or the like.
It is fixed by 2, and the flexible connecting member 8 such as a wire is penetrated and connected to the hole 6b provided on the upper surface side. Both ends 8a of the connecting member 8 are provided with the protrusions 5 provided on the stopper 5.
