The present invention also relates to an opening/closing mechanism that can be tightly closed, and relates to an opening/closing device that can be used in a wide range of applications, such as opening and closing doors and windows, opening and closing furniture, and other applications.

Thus, the present invention has a flexible left opening/closing sheet 1 whose upper end is fixed and is hanging down, and a left end 2.
It consists of a flexible right side opening/closing sheet 2 whose upper end side is fixed and hanging so that a is in contact with the right side edge 1a of the left side opening/closing sheet 1, or the right side opening/closing sheet 1 or the right side opening/closing sheet 1. A flexible string-shaped or band-shaped magnet 3 is provided on one of the left ends 2a of the sheet 2 and extends vertically from the top to the bottom, and the other is provided with a magnet 3 that extends vertically from the top to the bottom. An opening/closing device characterized by being provided with a flexible string-shaped or band-shaped magnet or magnetic body 4 that is attracted to the opening/closing device, and a flexible left-side opening/closing sheet 1 whose upper end side is fixed and hangs down. , the left side end 2a is the right side end 1 of the left side opening/closing seat 1
It is composed of a flexible right side opening/closing sheet 2 whose upper end side is fixed and hanging down so as to be in contact with the left side opening/closing sheet 1, and either the right side end 1a of the left side opening/closing sheet 1 or the left side end 2a of the right side opening/closing sheet 2. One side is provided with a flexible string-like or band-like magnet 3 that extends vertically from the top to the bottom, and the other side is provided with a flexible string-like magnet 3 that extends vertically from the top to the bottom and is attracted to the magnet 3. Alternatively, a strip-shaped magnet or magnetic body 4 is provided and either the lower end of the left opening/closing sheet 1 and the right opening/closing sheet 2 or the lower end fixed side 5 fixed at the position where these lower ends abut, respectively. is provided with a magnet 6 for closing the lower part, and the magnet 6 for closing the lower part is provided on the other side.
This opening/closing device is characterized by being provided with a lower closing magnet or magnetic body 7 which is attracted to the lower part.

Examples of the present invention will be described below.

The left opening/closing seat 1 and the right opening/closing seat 2 are mainly composed of insect netting, cloth, lace, etc.

In addition, the left opening/closing seat 1 and the right opening/closing seat 2
As shown in FIG. 1, a weight 8 may be provided at the lower end of each of the left opening/closing sheets 1 and the right opening/closing sheet 2 to hang down properly when closed.

In addition, by fixing the left end side of the left opening/closing seat 1 and the right end side of the right opening/closing seat 2, the sixth
The closing shown in the figure may be done properly, and the opening may be made by simply pressing the attracted magnet 3 and the magnet or magnetic body 4, but the left opening/closing seat 1 and the right opening/closing seat If the weight of the device 2 is large, for example because the width of the device is long, the same effect can be obtained without taking the above measures.

Further, as shown in FIG. 1, a locking tool 9 is provided at the right end 1a of the left opening/closing seat 1 and the left end 2a of the right opening/closing seat 2. Locking bracket 1 provided above
It may be possible to keep it open at all times by locking it at zero.

In addition, as a mechanism for keeping this always open, runners are provided at the upper ends of the left opening/closing sheet 1 and the right opening/closing sheet 2 like a double-opening curtain, and a rail is provided on which these runners slide. It may be possible to leave the
Even in this case, the left side opening/closing seat 1 is fixed at its upper end and hangs down so that it can be opened and closed as shown in FIG. The upper end side must be fixed and hang down so as to be in contact with 1a.

Therefore, mechanisms that satisfy this requirement, e.g.
It is necessary to adopt a mechanism that connects the upper right end of the left opening/closing seat 1 and the upper left end of the right opening/closing seat 2.

Further, the magnet 3, the magnet or magnetic body 4, the lower closing magnet 6, and the lower closing magnet or magnetic body 7 are made of a flexible material such as synthetic resin or rubber mixed with powder such as ferrite. A magnet is formed by further magnetizing this powder.

However, the lower end closing magnet 6 or the lower end closing magnet or the magnetic body 7 provided on the lower end fixed side 5
Since these do not need to be flexible, ordinary hard ones may be used, and as shown in FIGS. They may be provided so as to extend along the entire edge of the lower end fixed side 5, respectively.

The objects shown in FIGS. 1 to 4 are those in which the present invention is applied to screens for doorways, and numeral 11 in the figures indicates an insect screen.

Further, in the figure, 12 is a vertical frame attached to a vertical pillar 13 of a doorway etc., 14 is an upper frame attached to a lintel 15 of a doorway etc., and the left side end 1a of the insect screen 11 which is the left opening/closing sheet 1; The right side end 2b of the insect screen 11, which is the right opening/closing sheet 2, has vertical frames 12 and 1, respectively, as shown in FIG.
2 with the mesh pressers 12b, 12b that fit into the fitting grooves 12a, 12a, and the upper edges 1c, 2c of the upper frame 14, as shown in FIG. Net presser 1 fitted to 14a
It is attached with 4b.

Further, 16 in the figure is a holder, and the magnet 3, the magnet or the magnetic body 4 are embedded in this holder 16, and the right end 2b of the insect repellent net 11 which is the left opening/closing sheet 1, and the insect repellent which is the right opening/closing sheet 2. Net 11
It extends from the upper part to the lower part of each left end 1b and is provided along the entire line.

Further, numeral 17 in the figure is a holder for the lower closing magnet 6 or the lower closing magnet or the magnetic body 7.

18 in the figure is a lower frame attached to a threshold 19 of a door, etc., and a lower closing magnet 6 is attached to this lower frame 18.
Alternatively, a lower closing magnet or magnetic body 7 is provided buried therein.

Incidentally, FIG. 4 is a diagram showing a state in which the lower closing magnet 6 and the lower closing magnet or magnetic body 7 are attracted to each other.
A modification of FIG. 3 is shown.

Above, the screen door has been described as one of the uses of the present invention, but in addition, the left opening/closing seat 1 and the right opening/closing seat 2
By making it of cloth, lace, etc., it can be used as a partition or a curtain for a window, etc. Also, the present invention can be used as shown in FIG. By using a vinyl material, it may be used for opening and closing a storage room for frozen foods, etc., as shown in FIG. 5B, for example, for opening and closing a simple dance, etc.

When the opening/closing device according to the present invention configured as described above is opened, as shown in FIG. It expands, opens, and closes naturally without requiring any means.

That is, when closing the opening 20, which is wide at the base as shown in FIG. 6A, when the hand that was opening it is released, the left opening/closing seat 1 opens as shown in FIG. 6B→C→D→E. Due to the drooping of the right opening/closing seat 2 and the attraction force between the magnet 3 and the magnet or magnetic body 4, the right end 1a of the left opening/closing seat 1 and the left end 2a of the right opening/closing seat 2 are closed as if with a fastener. By sequentially adsorbing each other from the top to the bottom, it can be closed tightly and naturally without the need for any means.

In addition, the left opening/closing seat 1 and the right opening/closing seat 2
A lower end closing magnet 6 is provided on either the lower end of each of the lower ends or the lower end fixed side 5 fixed at a position where these lower ends contact each other, and the lower end closing magnet or magnetic body 7 is provided on the other side. In this case, the lower end of the opening 20 is also securely closed by the attraction between the lower closing magnet 6 and the lower closing magnet or the magnetic body 7.

As described above, the present invention relates to an opening/closing device that can be closed naturally and tightly without the need for any means, and the scope of its application is not limited to the above-mentioned one, but can be widely used.
