DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] An opening device according to an embodiment will be described below with reference to the drawings. The following embodiment shows one aspect of the present disclosure, does not limit the present disclosure, and can be modified as desired within the scope of the technical idea of ​​the present disclosure. In the following drawings, the scale of each structure is different from the actual structure in order to make each configuration easier to understand.

[0009] The opening device 100 shown in Fig. 1 is a building material and is used as a window for a house, a device for partitioning an opening in a factory, a device for partitioning an opening in a room of a building, etc. The opening device 100 includes a frame 1, an opening / closing member 2, and a gas introduction part 3.

[0010] The left-right direction when the opening device 100 is viewed from the front is referred to as the left-right direction. The horizontal direction perpendicular to the left-right direction is referred to as the depth direction. The direction perpendicular to the left-right direction and the depth direction is referred to as the up-down direction.

[0011] The frame 1 is formed in a four-sided frame shape. The frame 1 has a pair of left and right vertical frames 11, 11, an upper frame 12, and a lower frame 13. The pair of vertical frames 11, 11 are arranged apart in the left-right direction. The upper frame 12 connects the upper ends of the pair of vertical frames 11, 11 to each other. The lower frame 13 connects the lower ends of the pair of vertical frames 11, 11 to each other. The inside of the frame 1 is an opening 1a.

[0012] The opening / closing material 2 is disposed inside the four-sided frame 1. The opening / closing material 2 is made of a soft material. The opening / closing material 2 is made of, for example, soft resin or fiber. In the case of fiber, it is preferable to coat the surface with a material having weather resistance, water resistance, crime prevention, flying object resistance, fire resistance, heat resistance, etc. The opening / closing material 2 is made of a material having translucency such as transparency or milky white color.

[0013] The opening / closing material 2 has a plurality of strip-shaped portions 21. Each strip-shaped portion 21 has a shape that is long in the left-right direction. The strip-shaped portion 21 can be filled with gas. Each strip-shaped portion 21 has a bag shape. The outer periphery of each strip-shaped portion 21 is formed of a soft material.

[0014] 2, the strip portions 21 are arranged side by side in the up-down direction. The strip portions 21 adjacent to each other in the up-down direction are joined to each other.

[0015] The uppermost band-shaped portion 21u has an injection port 22 formed therein through which gas can be injected. The upper and lower band-shaped portions 21 have communication passages 23 through which gas can communicate with each other. The injection port 22 may be formed in a band-shaped portion 21 other than the uppermost band-shaped portion 21u.

[0016] When the band-shaped portion 21 is filled with gas, the opening / closing material 2 expands to a closed state in which it completely blocks the inside of the frame 1. The opening / closing material 2 may be configured to expand to block a part of the inside of the frame 1, such as the upper side.

[0017] 3, a groove 15 is formed in the vertical frame 11, recessed toward the opposite side from the center in the left-right direction. The left-right end 21a of the belt-shaped portion 21 is fitted into the groove 15. A resin or the like may be provided on the surface of the end 21a of the belt-shaped portion 21 to improve adhesion with the groove 15.

[0018] 2, a bottom bar 24 is provided below the bottommost band-shaped portion 21d. The bottom bar 24 is heavier than the band-shaped portion 21 and functions as a weight. The bottom bar 24 is made of, for example, an aluminum resin composite material.

[0019] 1, a wire 29 is connected to the left and right ends 24a of the bottom bar 24. The upper end of the wire 29 is connected to a wire winding portion (not shown) that is installed on the frame 1. When the opening / closing member 2 opens the opening 1a, the wire 29 is wound around the wire winding portion, and is configured to pull the bottom bar 24 upward.

[0020] 4, a groove 16 recessed downward is formed in the lower frame 13. The bottom bar 24 is fitted into the groove 16 when the opening / closing member 2 is in the closed state.

[0021] The gas introduction part 3 is a device for introducing gas into the inside of the opening / closing material 2. The gas introduction part 3 is, for example, an air pump or a compressor. The gas introduction part 3 may have an exhaust function for discharging gas from the inside of the opening / closing material 2. The gas injected into the gas introduction part 3 is, for example, air, argon gas, krypton gas, etc. When argon gas or krypton gas is used as the gas, the gas introduction part 3 may be connected to a tank (not shown) for storing the gas.

[0022] The gas introduction part 3 is installed, for example, on the upper side of the frame 1. The gas introduction part 3 and the injection port 22 of the opening / closing member 2 are connected by a connection pipe 31.

[0023] 5, when gas is exhausted from the band-shaped portions 21 of the opening / closing material 2, each band-shaped portion 21 contracts and becomes folded and is accommodated in the accommodation space 12S formed in the upper frame 12. When exhausting gas from the band-shaped portions 21, the gas may be exhausted from an exhaust port (not shown) formed in the band-shaped portions 21, or the gas may be forcibly exhausted from the gas introduction portion 3 equipped with an exhaust function.

[0024] As gas is discharged from the band-shaped portion 21, the opening / closing material 2 contracts and enters an open state in which the inside of the opening 1a of the frame 1 is open. The opening / closing material 2 may be pulled up by a lifting portion (not shown) so that the entire opening / closing material 2 is accommodated in the accommodation space 12S of the upper frame 12.

[0025] When air is introduced from the gas introduction section 3 through the connection pipe 31 and the injection port 22 into the inside of the band-shaped section 21, the band-shaped section 21 gradually expands. The weight of the bottom bar 24 gradually displaces the entire opening / closing material 2 downward. The left and right ends 21a of the band-shaped section 21 are guided by the groove 15 of the vertical frame 11 and can move straight down. The configuration may be such that the expansion of the opening / closing material 2 is controlled to finish when the bottom bar 24 reaches and fits into the groove 16 of the lower frame 13.

[0026] In the opening device 100, the opening / closing material 2 expands with gas introduced from the gas introduction section 3, thereby closing the opening 1a inside the frame 1. The opening / closing material 2 opens the opening 1a inside the frame 1 by contracting as the gas is discharged. With the opening 1a open, the opening / closing material 2 contracts and becomes less noticeable, thereby improving the aesthetic appearance.

[0027] The opening and closing material 2 is made of a soft material. It can be expanded smoothly by introducing gas into the opening and closing material 2, and can be contracted smoothly by discharging the gas.

[0028] Since the opening and closing material 2 is made of a material having translucency, it has excellent lighting properties and can further improve the aesthetic appearance.

[0029] A bottom bar 24 serving as a weight is provided under the lower part of the lowest belt-like portion 21d of the opening / closing material 2. When the opening / closing material 2 closes the opening 1a, the weight of the bottom bar 24 promotes the expansion of the opening / closing material 2 and the downward movement of the opening / closing material 2.

[0030] When the opening and closing material 2 expands and contracts, the end 21a of the opening and closing material 2 is guided by the groove 15 of the frame 1. When the opening and closing material 2 expands and contracts and is displaced, it can move smoothly along the groove 15.

[0031] Since the inside of the band-shaped portion 21 of the opening / closing material 2 is filled with gas, the heat insulating property of the opening / closing material 2 can be improved.

[0032] (Variation 1) An opening device 100A according to the first modification will be described mainly with reference to Fig. 6. In the modifications described below, configurations corresponding to those in the embodiment described above may be given the same reference numerals and descriptions thereof may be omitted.

[0033] As shown in Fig. 6, in this modified example, the opening / closing material 2A has a bag body 25. When the opening / closing material 2A is in a closed state, the bag body 25 has a shape corresponding to the opening 1a of the frame 1. The bag body 25 can be filled with gas. When filled with gas, the bag body 25 has a substantially flat bag shape. The outer periphery of the bag body 25 is formed of a soft material.

[0034] In the opening device 100A, the opening / closing material 2A expands with gas introduced from the gas introduction section 3, thereby closing the opening 1a inside the frame 1. The opening / closing material 2A opens the opening 1a inside the frame 1 by contracting as the gas is discharged. With the opening 1a open, the opening / closing material 2A contracts and becomes less noticeable, thereby improving the aesthetic appearance.

[0035] In the closed state, both sides of the opening / closing member 2A in the depth direction are substantially flat, resulting in a simple design.

[0036] (Variation 2) An opening device 100B according to the second modification will be described mainly with reference to FIG.

[0037] 7, in this modification, the opening / closing material 2B has a bag body 25 and a support frame 26. The support frame 26 has a four-sided frame shape in a plan view. When the opening / closing material 2B is in a closed state, a plurality of support frames 26 are arranged at intervals in the vertical direction. The outer peripheral surface of the support frame 26 is joined to the inner peripheral surface of the bag body 25.

[0038] In the opening device 100B, the opening / closing material 2B expands with gas introduced from the gas introduction section 3, thereby closing the opening 1a inside the frame 1. The opening / closing material 2B opens the opening 1a inside the frame 1 by contracting as the gas is discharged. With the opening 1a open, the opening / closing material 2B contracts and becomes less noticeable, improving the aesthetic appearance.

[0039] Since multiple support frames 26 are arranged at intervals in the vertical direction, when the opening / closing material 2B is in the closed state, the bag body 25 is prevented from expanding too much in the depth direction, making it easier to maintain its shape.

[0040] (Variation 3) An opening device 100C according to the third modification will be described mainly with reference to FIG.

[0041] As shown in Fig. 8, in this modified example, the opening / closing material 2C has a bag body 28. When the opening / closing material 2C is in a closed state, a shallow crease 28a remains in the bag body 28. When the opening / closing material 2C is in an open state, the bag body 28 is folded along the crease 28a and contracts. The crease 28a may be formed by a folding method such as Miura folding (registered trademark).

[0042] In the opening device 100C, the opening / closing material 2C closes the opening 1a inside the frame 1 by expanding with the gas introduced from the gas introduction part 3. The opening / closing material 2C opens the opening 1a inside the frame 1 by contracting as the gas is discharged. With the opening 1a open, the opening / closing material 2C contracts and becomes inconspicuous, improving the aesthetic appearance.

[0043] When the opening / closing material 2C is in the open state, the folds 28a form a pattern, resulting in a surface material with a design that has never been seen before. By coloring the folds 28a to match the folds 28a or making the folds 28a into a pattern, the design can be further improved.

[0044] (Variation 4) An opening device 100D according to the fourth modification will be described mainly with reference to FIGS.

[0045] 9 and 10, in this modification, a winding device 14 is installed on the upper frame 12. The winding device 14 is disposed in the accommodation space 12S. In the open state shown in FIG. 10, the opening / closing material 2 is wound around a shaft 14a of the winding device 14.

[0046] In the opening device 100A, the opening / closing material 2 expands with gas introduced from the gas introduction section 3, thereby closing the opening 1a inside the frame 1. The opening / closing material 2 opens the opening 1a inside the frame 1 by contracting as the gas is discharged. With the opening 1a open, the opening / closing material 2 contracts and becomes less noticeable, thereby improving the aesthetic appearance.

[0047] When the open / close member 2 is in the open state, the open / close member 2 is wound around the shaft 14a, thereby facilitating the discharge of gas from inside the band-shaped portion 21.

[0048] Although the preferred embodiments of the present disclosure have been described above with reference to the accompanying drawings, it goes without saying that the present disclosure is not limited to the examples. The shapes and combinations of the components shown in the above examples are merely examples, and various modifications can be made based on design requirements, etc., without departing from the spirit of the present disclosure.

[0049] In the above embodiment, the opening / closing member is displaced in the up-down direction, but the present invention is not limited to this example. For example, the opening / closing member may be displaced in any direction, such as the left-right direction.

[0050] In the embodiment described above, an example was shown in which the groove for guiding the end of the opening / closing material is formed in the vertical frame, but this is not limited to this example.
