Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roll blind device having a screen that allows wall openings such as windows to be opened and closed.

A known roll blind device is one in which a screen made of cloth or plastic, for example, is wound around a winding device having a suitable braking mechanism and a coil spring, and is placed above a wall opening such as a window. If necessary, the drawer can be expanded and closed to cover the opening to provide light shielding, heat insulation, etc., or it can be placed in an appropriate location in the room to act as a simple partition. I am using it.

However, in conventional roll blind devices, the screen is simply pulled out to an appropriate position, or a horizontal bar attached to the tip of the screen is hooked and fixed at a position such as the middle or bottom of the opening. Although it is easy to handle and has a good design, both sides of the unfolding screen are simply stretched in a free state. Therefore, if you try to block out direct sunlight with such a blind device, for example, although the area behind the screen is good, direct light will enter through the gap between the window frame and the screen, and the area that receives this incident light will be affected. There is no point in using a blind device at all, and especially when there are consecutive windows and the device is installed in each window, the problem is that the sun leaks in the window is bothersome and extremely inconvenient. . Also, when this screen is used as a cover for an open window on a summer night, it is preferable because the night breeze enters through the free parts on both sides of the screen, giving a cool feeling. However, it is inconvenient and has the disadvantage of exhibiting conditions that are even more unfavorable than the ventilation effect.Furthermore, even if it is used for the purpose of heat insulation, the effect cannot be fully demonstrated due to the presence of gaps on both sides. It was hot too.

In view of the above-mentioned drawbacks, the present invention provides a screen that can open and close an opening in a wall surface, and an opening around the opening, so that the opening can be opened and closed completely when the opening is opened, and is easy to handle. In a roll blind device configured such that a magnetic coupling member that magnetically attaches to each other is disposed on the frame or the wall circumferential surface portion that fixes the opening frame, and the opening is closed by this magnetic attachment, The screens are mounted in multiple layers, and a magnet or magnetic material is formed in a plane on at least both sides and the lower peripheral surface of each screen, and a magnet or magnetic material is formed in a planar shape on at least both sides and the lower peripheral surface of the opening, and a magnet or magnetic material is formed on the peripheral surface of the opening frame or wall at least on both sides and the lower part of the opening from the opening side. It is characterized by a multi-step planar magnetic body or magnet that protrudes in steps, and when the screen is expanded and closed, its magnetic coupling action creates a space between the inside and outside of the screen. It is an object of the present invention to provide a roll blind device which is constructed so as to be divided in different states, and which ensures the performance of various functions such as insect prevention, heat insulation, sound insulation, etc. as well as the light shielding property of the screen.

The present invention will be described in more detail below based on the illustrated embodiments. Fig. 1 is a front view of the roll blind device as the premise of the present invention with the screen unfolded, and Fig. 2 is the same as that shown in Fig. 1. FIG. 1 is a cross-sectional view taken along the line in FIG. 1, and FIG. 3 is a longitudinal sectional view taken along the line in FIG. 1 is a roll blind device, 2 is its screen, which is made of cloth or plastic sheet, etc. On the back side in FIG. 1 when the drawer is unfolded,
One magnetic strip made of a strip-shaped plastic sheet mixed with magnetic powder or a thin layered plate of magnetic material is placed at a position corresponding to the strip-shaped magnet 4 disposed on the peripheral surface of the opening of the wall 5, which will be described later. A strip-shaped magnetic body 2a serving as a coupling member is attached by being integrally joined or embedded, and a decorative pattern 2b is appropriately formed on the surface side. Reference numeral 3 designates a screen winding unit, which is horizontally mounted and fixed on the upper wall surface of a window 6, which will be described later.A known coil spring and braking mechanism (not shown) are disposed on the winding shaft 3a, and the screen 2 is One end is fixed, and the screen 2 is appropriately stopped at the drawn-out position by pulling out from the winding section 3, and can be rolled up by lifting. 4 is a thin strip magnet as the other magnetic coupling member, which is made of a magnetized steel plate, a magnetized plastic plate mixed with magnetic powder, etc., and is attached to a window frame 7 or a wall 5 around the window frame, which will be described later. It is attached and fixed to the surrounding circumferential surface by adhesives, screws, etc. 5 is a wall, 6 is a window as an opening provided in the wall 5, and a window frame 7 and a glass door 8 are arranged around the wall.

Therefore, according to the blind device configured as described above,
For example, the screen 2 is made of a sheet made of completely light-shielding or semi-transmissive plastic, cloth, etc.
When the blind device 1 is used as a light shielding device, when the screen 2 is pulled out and unfolded, a band-shaped magnetic body 2a is integrally assembled on the four sides of the portion of the screen 2 that corresponds to the window 6.
On the other hand, a band-shaped magnet 4 is disposed on the wall 5 around the corresponding window 6, so if the screen 2 pulled out to a predetermined position in a direction slightly away from the window side is pressed against the window side, the band-shaped magnetic material 2a and The magnets 4 are attracted to each other by magnetic action and are stably locked in a predetermined position, and at the opening, the screen 2 is separated between the inner and outer parts without any gaps. As a result, all light is blocked between the inside and outside of the screen 2, or the light becomes uniformly semi-transparent, so that indoor light at night is blocked from the outside, and light entering the room during the day is blocked. The function of blocking the incidence of direct light can be easily and completely performed without causing any light leakage.

Furthermore, if the screen 2 is similarly constructed of a net-like sheet made of plastic, cloth, etc., when it is unfolded in the same manner as described above, the screen 2 will move around the opening of the window 6 due to the magnetic coupling action. Since the outside is stretched without any gaps, even if the glass door 8 of the window 6 is opened, the entry route for insects etc. is completely cut off, and in this case, it can function as an insect screen.

Furthermore, if the screen 2 is made of a sheet of heat insulating or sound insulating material made of plastic, cloth, etc., when the screen 2 is unfolded in the same manner as described above, the screen 2 will close the opening by the same magnetic coupling effect as described above. Furthermore, in this case, an airtight air layer can be interposed between the glass door 8 and the glass door 8, so that heat insulation and sound insulation effects can be more effectively and completely performed. Condensation on the window surface can also be prevented, and the blind device 1 can be used as an excellent heat insulating device or sound insulating device.

In addition, in the above-mentioned prerequisite example, the screen winding section 3
If it can be removably set on an appropriate support member (not shown) attached to the wall 5, the above-mentioned different functions can be arbitrarily replaced and set depending on the season and purpose. Extremely convenient. Furthermore, if a suitable tongue piece, string, etc. is attached to the center of the lower end of the screen 2, it will be convenient for the drawer operation.

Figures 4 and 5 show an embodiment of the present invention, with Figure 4 being a sectional view of the main part showing the locking part between the screen and the window periphery, and Figure 5 being a sectional view of the screen winding part. It is a diagram. Note that the same reference numerals are given to the same parts as in the above-mentioned prerequisite example, and the explanation thereof will be omitted. The invention has multiple screens, shown as triple in the figure. Roll blind device 1
One end of each of the screens 12A, 12B, and 12C is fixed to winding shafts 13a, 13b, and 13c that are disposed at appropriately shifted positions in the screen winding section 13, respectively. Also, each screen 12A, 1
Band-shaped magnetic bodies 12a, 12 integrally attached to the peripheral surface portions of the openings 2B, 12C when deployed
b, 12c are formed so as to have a frame shape that becomes larger sequentially from the screen on the window 6 side, and are arranged and formed so as to take positions shifted in the plane direction of the screen. On the other hand, in this case, the strip magnet 14 similar to the above-mentioned example attached to the window frame 7 or the circumferential surface of the wall 5 around the window frame is
It has a width that covers the entire width of the strips b and 12c arranged in parallel, and in the cross-sectional shape, each strip-shaped magnetic body 12
The parts corresponding to a, 12b, and 12c are sequentially attached to the wall 5.
It is formed to be higher than the surface.

Therefore, according to the present invention, whereas the above-mentioned prerequisite example has a configuration in which components each having a separate function are installed individually depending on the purpose, these components are integrated into one, so for example, If the screen 12A is a net-like insect-proof screen similar to the above embodiment, the screen 12B is a semi-transparent light-shielding screen, and the screen 12C is a heat-insulating or sound-insulating screen, the necessary You can draw out and set up the required screen depending on the situation.For example, during the daytime, only the light-blocking screen 12B can be pulled out and set, and at night in summer, only the insect-proof screen 12A can be pulled out, or in addition, the upper half can be insulated or expanded to hide the screen. The sound insulation screen 12C can be pulled out, or only the insulation or sound insulation screen 12C can be pulled out at night during winter, allowing for easy use depending on the situation. Also, of course all screens 12A,
It is also possible to set up drawers 12B and 12C at the same time. In this way, even if all the screens are set up at the same time or some of them are drawn out, each screen has its peripheral strip-shaped magnetic bodies 12a, 12b, and 12c coupled to the strip-shaped magnet 14 independently. Each screen can be separated between the inside and outside without any gaps, allowing each screen to fully demonstrate its functions.

In addition, in such a composite screen type roll blind device, the combination and arrangement order of the screens can be arbitrarily set, and the number of screens can be arbitrarily set.
3, it is also possible to configure it so that it can be removed and replaced.

Although FIG. 6 and FIG. 7 are not examples of the present invention,
This is an example of an application of the above-mentioned prerequisite example. In these cases, some of the screens are left as they are without magnetically acting members, and other screens are provided with magnetically acting members to create a gapless state. 6th
In the case of the roll blind device 22 shown in the figure, for example, the light-shielding screen 22A has a portion that overlaps with the band-shaped magnet 24, but the screen is left as is, and the insect-proof screen 22B has a band-shaped magnetic material 22b arranged around its periphery. Yes, insect screen 22
When only B is set to be deployed, the magnetic body 22b is directly attracted and coupled to the strip magnet 24, and when the light-shielding screen 22A is also set to be deployed, the magnetic body 22b of the insect-proof screen 22B is connected to the strip-shaped magnet through the light-shielding screen 22A. 24, the screen 22A is indirectly fixed and forms a gapless state. In the case of the roll blind device 32 shown in FIG. 7, for example, the heat insulating or sound insulating screen 32A has a size such that its peripheral edge touches the wall 5 surrounding the opening, but the screen is left as it is. , the insect screen 32B is larger than the screen 32A,
A strip magnetic material 32b is arranged around the wall 5, and a strip magnet 3 is placed on the wall 5 so as to correspond to the magnetic material 32b.
4 are arranged. Further, on the indoor side of the screen 32B, a light-shielding screen 32C whose surface is appropriately decorated with a pattern or the like is arranged on the indoor side of the screen 32B.
It is designed to be formed and set to the same size as. Therefore, in this case, if only the insect screen 32B is set to unfold, the screen 32B
The magnetic material 32b is directly attracted and coupled to the strip magnet 34 and held in a gap-free state, and if the heat insulating or sound insulating screen 32A is deployed at this time, the screen 32A is attached to the wall 5 by the screen 32B.
Since the screen 32B is held pressed against the screen 32B, the screen 32B is also held substantially without gaps. In addition, the screen 32C is a screen having a decorative design, and in this case functions as a decorative screen that also has a light shielding function.

Note that the roll blind device of the present invention is not limited to the configuration of the above-described embodiment; for example, the arrangement of the magnetic coupling members may be reversed, and the shape thereof may be arbitrary. Well,
It is also possible to impregnate or weave a magnetic material into a predetermined part of the sheet, and the application is not limited to high windows.
Of course, the invention can also be applied to other wall openings such as sweep windows and doorways, and the structure of the screen winding section is also arbitrary.

As described above, according to the roll blind device of the present invention, the installation opening can be completely opened completely, and the peripheral edge of the screen can be magnetically coupled to the opening during the unfolding and closing operation. Therefore, by using screens with various functional purposes at openings such as windows, various functions such as light shielding, ventilation, insect prevention, heat insulation, and sound insulation can be combined. When one of the composite features is a heat-insulating and sound-insulating screen, a sealed air layer is formed between the screen and the window surface, making its function even more reliable. In addition, as a result of preventing dew condensation on the window surface due to temperature differences between indoors and outdoors, the window frame etc. will not corrode and the glass will not be stained. Because it is based on a bonding action, the structure is simple and the device can be made compact, without impairing the decorativeness of the interior, or without special processing on conventional windows, etc. It has great features such as being easy to install.
