Description

[Detailed description of the invention] (Field of industrial application) The present invention is a blind that functions as a sunshade and adjusts the amount of light. The present invention relates to a blind having an appearance.

(Prior art and its problems) Traditionally, blinds used to shade the sun and adjust the amount of light have been Venetian blinds, which are composed of a number of tiltable slats lined up in the horizontal direction, and venetian blinds, which are made up of a number of tiltable slats arranged in a horizontal direction, and blinds, which are about 10 cm long and whose angle can be adjusted. There are blind curtains and the like that are made of vinyl leather tapes of various widths hung vertically in parallel.

However, these blinds use deep slats or tape, and require a certain depth for adjustment to block sunlight. Moreover, it had the appearance of a large number of slats or tapes arranged independently in parallel.

An object of the present invention is to provide a blind having a configuration different from that described above, which does not take up much depth, has a planar continuous appearance, and is also equipped with various light dose adjustment functions.

(Means for Solving the Problems) For this purpose, the present invention has a plurality of sheets in which a large number of elongated light-transmitting parts are arranged side by side at a predetermined interval on a substantially rectangular sheet, so that the elongated directions of the light-transmitting parts coincide with each other. A transparent synthetic resin sheet is preferably bonded to at least one of the front and back sides of at least one of the sheets, and the sheet is attached to the upper end of at least one of the sheets perpendicular to the elongated direction of the transparent part. The blind is characterized in that a magnetically attached part for sliding in the direction is provided, and an electromagnet capable of magnetically attaching the magnetically attached part is disposed at a position above the magnetically attached part at a predetermined interval to form a blind.

(Function) When the above electromagnet is energized, the magnetic part on the top of the seat is magnetically attached to the electromagnet, so the seat slides upward, and when the energization is stopped, the magnetic part on the top of the seat separates from the electromagnet and slides downward. . The amount of light passing through the blind is maximized when the transparent parts of the stacked sheets are brought into alignment by sliding the sheets up and down. Moreover, when the light-transmitting part of a sheet is superposed on the non-light-transmitting part between the light-transmitting parts of another sheet, shielding can be performed.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

The blind 1 of the first embodiment is shown in FIGS.
As shown in the figure. The blind 1 includes a framed sheet 2 made of two sheets 22 stretched inside a rectangular frame 21 having a size corresponding to the opening size of the window in which the blind is installed, and two framed sheets overlapped with each other. 2, and electromagnets 41 and 42 fixed to the inside of the upper frame 33 of the outer frame 3.

The frame 21 of the framed sheet 2 is made of hollow aluminum with a vertically long rectangular cross section and a narrow depth, and is lightweight and resistant to deformation when the sheet 22 is stretched inside the frame. It has no strength. A plurality of magnetic pieces 23 made of magnetic metal such as iron or stainless steel are fixed to the upper surface of the frame 21 at appropriate intervals. The sheet 22 of the frame sheet 2 is a transparent sheet made of synthetic resin such as vinyl chloride and has a fixed width A.
Opaque tapes (for example, 1 cm) are pasted parallel to the upper and lower frames of the frame 21 at predetermined intervals A, forming a large number of band-shaped transparent parts 24 and non-transparent parts 25.

The outer frame 3 has a substantially U-shape in which the cross section of each of the four frames is open toward the inside of the blind, and the outer frame 3 has two
It is fitted onto the frame 21 of the frame sheet 2. The inner height of the lower frame 31 of the outer frame 3 is the vertical height of the left and right vertical frames 32, 32.
is formed higher than the inner width of the sheet 22 by at least the width A of the transparent part 24 (or non-transparent part 25), and two framed sheets 2 are placed on the inner bottom of the lower frame 31. ing. At this time, the transparent part 24 (or non-transparent part 25) of the sheet 22 of the frame sheet 2
is completely aligned in height with the light-transmitting portion 24 (or non-light-transmitting portion 25) of the other sheet 22. The inner height of the upper frame 33 of the outer frame 3 is higher than that of the lower frame 31. On the inside of the upper frame 3, electromagnets 41 for magnetically attaching the magnetic pieces 23 are fixed upwardly at the distance A from each magnetic piece 23 of the frame sheet 2 on one side, and Electromagnets 42 functioning in the same manner as described above are also fixed at positions 1/2 of the interval A upward from each magnetic piece 23 of the attached sheet 2. The electromagnets 41 are electrically connected so that they are all energized at the same time, and the other electromagnets 42 are similarly connected, and the electromagnets 41 and 4
The two wirings are independent from each other.

The blind 1 having the above configuration is installed on a window. At this time, the two framed sheets 2 are placed on the lower frame 33 of the outer frame 3, and the height of the transparent part 24 of one framed sheet 2 and the transparent part 24 of the other one is The positions match as shown in FIG.

When one electromagnet 41 is energized, the magnetic piece 23 is drawn upward by its magnetic force, and the electromagnet 41
At the same time, the frame sheet 2 slides upward by the distance A. At this time, the positions of the transparent part 24 of one framed sheet 2 and the non-transparent part 24 of the other framed sheet 2 are aligned as shown in FIG. 5, and the light rays from outside the window are completely blocked. be done. When the electricity is turned off, the framed sheet 2 slides downward and returns to its original position.

When the other electromagnet 42 is energized, the electromagnet 41
Framed sheet 2 located below 1/2 interval from A is
Like the frame sheet 2, it slides upward and is magnetically attached, but the sliding interval is 1/2 of A. At this time,
Light rays from outside the window are blocked by only half of the original state.

The material of the frame 21 of the framed sheet 2 is not limited to aluminum as described at the beginning, but may be other materials as long as they are lightweight and have the necessary strength.

In addition, in order to form a transparent part and a non-transparent part on the sheet 2, in addition to pasting opaque tape on a transparent sheet as described above, printing with opaque ink on the sheet, or using a long and thin transparent sheet. It is also possible to form a sheet by adhering the ends of opaque sheets and making them continue alternately, or it is also possible to use a synthetic resin sheet in which a band-shaped non-transparent part is formed in advance. Further, as another example of the sheet, a sheet made of special steel or aluminum with a transparent portion formed by punching may also be used.

In the above embodiment, the spacing between the magnetic strip and the electromagnet was set to be the same or half of the width of the transparent and non-transparent portions of the sheet, but it is not limited to the above spacing. It can be set arbitrarily to obtain a shielding effect.

As a modification of the first embodiment, the following blind may be used. A sheet similar to the sheet 22 is suspended from a rod member on which a magnetic piece similar to that of the upper frame of the framed sheet 2 is formed, and both ends of the rod member are placed outside at the same positions as the upper frame of the framed sheet 2. When placed within the frame, the sheet slides upward by energization of the electromagnet, so that light can be shielded in the same manner as in the first embodiment.

By the way, the number of framed sheets installed within the outer frame can also be three or more. An example is shown in which three sheets with frames are installed. For example, as shown in FIG. 6, the width of the transparent portion 24a of the sheet 22a of each frame sheet is set to B, and the width of the non-transparent portion 25a is set to 1/2 of B. Three sheets of this framed sheet are polymerized,
The height positions of the transparent parts 24a are made to match each other. Here, among the three framed sheets, the first embodiment Arrange the electromagnet in the same way.

In the above-mentioned blind, since the area of the light-transmitting portion is wider than in the state before shielding is performed in the first embodiment, more light rays can be taken into the window. When shielding the light beam, as shown in Figure 7, turn on the electromagnet, slide one of the three framed sheets 2a upwards at a distance of 1/2 of B, and move the other sheet above B.
If you slide the gap upward, one sheet 22
The transparent portion 24a of the sheet 2a is connected to the other two sheets 22a, 2
Since it is completely covered by the non-transparent part 25a of 2a, the light beam is completely blocked.

When forming a blind by stacking three or more sheets, for example, if there are four sheets, compare the width of the transparent part of the sheet with that of the non-transparent part, and select the three sheets shown in Figures 6 and 7 above. If you form it even wider than the example,
A large amount of light can be transmitted and complete shielding can be achieved. Moreover, some of the plurality of sheets can be made into a translucent or colored material for reducing the amount of light, or can be made into a sheet for blocking ultraviolet rays.

Next, the blind 1b of the second embodiment, in which the frame sheet 2 is slid upward by another means, is installed in the eighth embodiment.
This will be explained with reference to FIGS. 10 to 10. Blind 1b is
An electromagnet in the outer frame from the blind 1 of the first embodiment,
The parts of the framed sheet excluding the magnetic piece are common.

Inside the upper frame 33b of the outer frame 3b of the blind 1b, both ends of magnetic metal rods 5 having a length shorter than 1/2 of the width of the blind 1b are placed on the frame sheet 2b. The center part of the frame and the end of the upper frame 33b of the outer frame 3b (the right end in the drawing) are supported by shafts 51 and 52 perpendicular to the surface of the blind 1b. 2b is placed on the lower frame 31b of the outer frame 3, the shaft 5
is at least an A interval higher than 1.

Above the magnetizing rod 5, an electromagnet 4b capable of magnetically attaching the magnetizing rod 5 is provided in an outer frame so as to be horizontally movable. A knob 6 for moving the electromagnet 4b is formed on the front surface of the outer frame.

The blind 1b having the above configuration is installed on a window. When the electromagnet 4b is energized, the magnetic rod 5 is magnetically attached by the electromagnet 4b, so it rotates upward at a certain angle around the shaft 52, and a frame pivotally supported by the shaft 51 is attached to the end of the magnetic rod 5. The attached sheet 2b slides upward. When the electricity is turned off, the magnetic rod 5 separates from the electromagnet 4b and the framed sheet 2b slides downward.

The rotation angle of the magnetizing rod 5 is large when the knob 6 is moved to set the electromagnet 4b at a position close to the shaft 52, and becomes smaller as the electromagnet 4b is moved away from the shaft 52. By moving the knob 6, the sliding interval of the framed sheet 2b can be set steplessly, and the light beam from outside the window can also be adjusted steplessly.

In addition, although the above example shows a framed sheet in which the light-transmitting part and the non-light-transmitting part are formed horizontally, the same applies to a framed sheet in which the light-transmitting part and the non-light-transmitting part are formed vertically. It is possible to block the rays of light. In this case, for example, magnetic pieces are fixed at appropriate intervals to the left and right vertical frames of a framed sheet in which a transparent part and a non-transparent part of width dimension A are formed vertically. Inside the frame, at a position A distance away from the magnetic piece to the left and right,
Fix the electromagnet for magnetically attaching the magnetic piece. According to this blind, the framed sheet slides in the direction of either the left or right electromagnet that is energized. Therefore, the light beam can be adjusted in the same way as in each of the embodiments described above.

(Effects of the invention) The present invention consists of stacking a plurality of sheets in which a large number of elongated light-transmitting parts are arranged side by side at predetermined intervals on a substantially rectangular sheet so that the elongated directions of the light-transmitting parts coincide with each other, and at least one of the sheets is A magnetically attached part is provided at the upper end of one sheet for sliding the sheet in a direction orthogonal to the elongated direction of the transparent part, and an electromagnet capable of magnetically attaching the magnetically attached part is disposed above the sheet. It is a blind that
The structure allows the amount of light passing through the blind to be adjusted by sliding the stacked sheets, so it does not take up much depth, causes less discomfort when installed, and can be installed in a wide range of locations.

In addition, since it has a structure in which sheets are layered, compared to Venetian blinds that have a horizontal flat surface, it has the advantage that dust and dust are less likely to accumulate on the surface, reducing the effort required for cleaning.

Furthermore, by appropriately selecting the widths of the light-transmitting portions and non-light-transmitting portions of the sheet, it is possible to produce various shielding effects.
