Description

The present invention relates to partition walls. The present invention also relates to a soundproof system in which each booth is partitioned by a partition wall.

2. Description of the Related Art Conventionally, conferences, which were held with attendees gathered in a conference room, have diversified with the introduction of teleconferencing systems such as TV conferences, teleconferences, and web conferences with the development of network environments such as the Internet. Teleconferencing systems are often used by a small number of people because they can hold a conference with a remote party at any time if the equipment is available. On the other hand, a conference room provided in an office often has a large space so that a large number of people can attend. Therefore, when holding a meeting with a small number of people, it is not possible to effectively utilize the space in such a large meeting room. A conference room for a small number of people can be provided in advance in an office, but a conference room for a small number of people cannot cope with a meeting with a large number of people. Therefore, in many cases, conference booths separated by partitions are provided as conference rooms for a small number of people in a corner of an office (Patent Document 1).

On the other hand, simply using a partition wall does not provide sufficient sound insulation, and when a plurality of conferences are held simultaneously, conversations between the conferences may be leaked, hindering the progress of the conferences. Therefore, a method has been proposed in which the entire wall is isolated by a partition wall, and an opening is provided in a part of the partition wall to share the space and have a conversation (Patent Document 2).

Thus, the partition wall 10 according to the present embodiment can isolate each booth, and can easily switch between the sound insulation state and the sound non-insulation state.

A partition wall 10 according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG.

[1. Overview of configuration of partition wall 10]
FIG. 1 is a schematic diagram of a partition wall 10 according to one embodiment of the present invention. Specifically, FIG. 1A is a perspective view showing the front, top, and right sides of the partition wall 10, and FIG. It is the perspective view which appeared. 1C is a right side view of the partition wall 10. FIG.

As shown in FIGS. 1A and 1B, the partition wall 10 includes a first translucent panel 110, a second translucent panel 112, and a bag body 120. As shown in FIG. First translucent panel 110 and second translucent panel 112 include first opening 114 and second opening 116, respectively. Each of the first opening 114 and the second opening 116 is provided with an opening 118 penetrating through the first translucent panel 110 or the second translucent panel 112 .

The first translucent panel 110 and the second translucent panel 112 may not have translucency as a whole, and may be partially translucent. At least, the first opening 114 of the first translucent panel 110 and the second opening 116 of the second translucent panel 112 should be translucent.

As shown in FIG. 1C, the first translucent panel 110 and the second translucent panel 112 are provided apart from each other. Moreover, the bag body 120 is inserted into the gap between the first translucent panel 110 and the second translucent panel 112 . A regulating valve 130 is attached to the bag body 120 .

The bag 120 can be inflated with air from the regulating valve 130, or can be deflated with air discharged. A regulating valve 130 attached to the bag 120 regulates the inflow and outflow of air from the bag 120 . Note that the bag body 120 shown in FIG. 1 shows a state in which air is injected and expanded.

The injection of air into and the evacuation of air from the bladder 120 can be accomplished using an injection device 132 and an evacuation device 134, respectively. As the device 132 for injecting air into the bag body 120, for example, an air compressor can be used. As the device 134 for discharging air from the bag body 120, for example, a pump can be used. The regulating valve 130 is preferably a three-way valve that can adjust the air path in three directions: an air inlet, an air outlet, and an inlet/outlet of the bag body 120 . Note that each of the air compressor, pump, and three-way valve described above is an example of the device 132 for injecting air into the bag body 120, the device 134 for discharging air, or the regulating valve 130, and the partition wall 10 can be configured in a manner other than these. is.

The expandable range of the bag 120 may be inside the gap between the first translucent panel 110 and the second translucent panel 112 or outside the gap. The bag 120 may be inflated so as to overlap at least the first opening 114 and the second opening 116 and close the opening 118 of the first opening 114 and the second opening 116 . The partition wall 10 can block the sound between the first translucent panel 110 side and the second translucent panel 112 side by closing the opening 118 . Moreover, the first translucent panel 110, the second translucent panel 112, and the bag body 120 of the partition wall 10 may be provided with an outer frame and housed in the outer frame. By providing the partition wall 10 with a frame, the range in which the bag body 120 can be inflated can be set within the frame.

FIG. 2 is a schematic cross-sectional view of the partition wall 10 according to one embodiment of the present invention. Specifically, FIG. 2A is a schematic cross-sectional view of the partition wall 10 in the non-insulating state, and FIG. 2B is a schematic cross-sectional view of the partition wall 10 in the sound insulating state.

As shown in FIGS. 2A and 2B, an elastic body 122 is attached inside the bag body 120 . The elastic body 122 is, for example, rubber or a spring, but is not limited to this. The elastic body 122 may be one that expands when a force is applied and contracts and returns to its original shape when the force is removed.

As shown in FIG. 2A, in the partition wall 10 in the non-insulating state, the bag body 120 is contracted and the elastic body 122 is also contracted (returned to its original state). Therefore, the bag 120 does not overlap the first opening 114 and the second opening 116 . In other words, the gap between the first opening 114 and the second opening 116 is not blocked by the bag 120 . Therefore, in the configuration of the partition wall 10 shown in FIG. can have a conversation through the first opening 114 and the second opening 116 .

On the other hand, as shown in FIG. 2B, in the partition wall 10 in the sound insulation state, the bag body 120 is inflated and the elastic body 122 is also stretched. The bag body 120 overlaps the first opening 114 and the second opening 116 . In other words, the gap between the first opening 114 and the second opening 116 is blocked by the bag body 120 . Therefore, in the configuration of the partition wall 10 shown in FIG. However, it is blocked by the bag body 120 and cannot have a conversation.

The partition wall 10 is switched between the non-insulating state and the sound-insulating state by air entering and exiting the bag body 120 . Specifically, by injecting air from the adjustment valve 130, the bag 120 is inflated and the elastic body 122 is stretched. The bag 120 expands along the first translucent panel 110 and the second translucent panel 112 to close the openings 118 of the first openings 114 and the second openings 116 (FIG. 2B). )). By closing the opening 118, the sound propagation path connecting the first opening 114 and the second opening 116 is blocked, and the first translucent panel 110 side and the second translucent panel 112 side are separated. sound insulated. On the other hand, by discharging air from the regulating valve 130, the bag body 120 is contracted and the elastic body 122 is contracted (restored). The bag body 120 is returned to its original position by the restoring force of the elastic body 122, and the closing of the openings 118 of the first opening 114 and the second opening 116 is released (FIG. 2(A)). By unblocking the opening 118, a sound propagation path connecting the first opening 114 and the second opening 116 is formed, and the first translucent panel 110 side and the second translucent panel 112 side are formed. It is possible to have a conversation with

As described above, the partition wall 10 expands or contracts the bag body 120 in the gap between the first translucent panel 110 and the second translucent panel 112, and the first opening 114 and the second opening 114 are opened. The sound insulation state and the non-sound insulation state can be switched by closing or unblocking the openings 118 of the openings 116 . The partition wall 10 can be installed in one corner of a room and used as a partition wall for a conference booth for a small number of people. Moreover, the partition wall 10 can also be installed as at least a part of the wall of the room. Since the partition wall 10 is translucent, it can also be used as a wall of a conference booth or a room with a sense of openness.

Below, the 1st translucent panel 110, the 2nd translucent panel 112, and the bag body 120 are demonstrated further in detail among the partition walls 10. FIG.

[2. First translucent panel 110 and second translucent panel 112]
The first translucent panel 110 and the second translucent panel 112 can transmit at least visible light. Therefore, first translucent panel 110 and second translucent panel 112 can use a translucent material. As the translucent material of the first translucent panel 110 and the second translucent panel 112, for example, glass or acrylic can be used. Since the first translucent panel 110 and the second translucent panel 112 have translucency, the partition wall 10 in the non-sound-insulating state also has translucency, and the first translucent panel 110 on the side of the first translucent panel 110 has translucency. The user and the second user on the side of the second translucent panel 112 can face each other and have a conversation. In addition, since the illumination light of the room or the sunlight from the window of the room passes through the partition wall 10, the room does not become dark when the partition wall 10 is installed in the room.

When the sound insulation of the partition wall 10 is to be improved, a panel having a high sound insulation effect can be used instead of the first translucent panel 110 and the second translucent panel 112 . As a panel with a high soundproofing effect, for example, a double structure plate having a hollow portion can be used. Also, the hollow portion may be provided with a sound absorbing material such as glass wool, rock wool, or foamed resin. Since sound is converted into thermal energy by providing the sound absorbing material, the sound absorption is improved.

The thickness of the first translucent panel 110 and the second translucent panel 112 may be any thickness that can withstand the expansion of the bag body 120 . That is, the thicknesses of the first translucent panel 110 and the second translucent panel 112 can be appropriately designed in consideration of the pressure of the injected air or the elastic force of the bag 120 or the elastic body 122. can.

The first translucent panel 110 and the second translucent panel 112 also include a first opening 114 and a second opening 116, respectively. Although a plurality of openings 118 are provided in each of first opening 114 and second opening 116 in FIGS. 1A and 1B, the number of openings 118 is not limited to this. At least one or more openings 118 may be provided in each of the first opening 114 and the second opening 116 . Moreover, although the cross-sectional shape of the opening 118 is circular in FIGS. 1A and 1B, the cross-sectional shape of the opening 118 is not limited thereto. The cross-sectional shape of the opening 118 may be, for example, elliptical or polygonal such as triangular or quadrangular. Furthermore, the side surfaces of the opening 118 may be tapered.

The size of the opening 118 is not particularly limited, but when the shape of the opening 118 is circular, the diameter of the opening 118 is, for example, 5 cm or more and 15 cm or less, preferably 10 cm or more and 15 cm or less. If the opening 118 is too small, even if the bag body 120 covers the first opening 114 and the second opening 116, the opening 118 cannot be completely closed, so that the soundproofing of the partition wall 10 is lowered. Become.

When a plurality of openings 118 are provided in each of the first openings 114 and the second openings 116, the plurality of openings 118 can be arranged in a matrix, but the arrangement of the plurality of openings 118 is limited to this. do not have. The arrangement of the plurality of openings 118 can be, for example, in a houndstooth pattern or randomly. 1A and 1B, the plurality of openings 118 are arranged such that each of the first openings 114 and the second openings 116 is rectangular. The arrangement is not limited to this. For example, the plurality of openings 118 can be arranged such that each of the first opening 114 and the second opening 116 is circular, oval, or polygonal.

Further, the opening 118 can be provided so that the opening surface of the opening 118 of the first opening 114 and the opening surface of the opening 118 of the second opening 116 are aligned when viewed from the front of the partition wall 10 . The position of 118 is not limited to this. The opening 118 can also be provided so that the opening surface of the opening 118 of the first opening 114 and the opening surface of the opening 118 of the second opening 116 partially overlap when viewed from the front of the partition wall 10 . Further, the opening 118 can be provided so that the opening surface of the opening 118 of the first opening 114 and the opening surface of the opening 118 of the second opening 116 do not overlap.

[3. bag 120]
Bag 120 can be inflated and deflated. Therefore, the bag 120 can use an elastic material that has the property of deforming when a force is applied and returning to its original shape when the force is removed. Examples of the elastic material of the bag 120 include natural rubber, silicone rubber, polyurethane rubber, fluororubber, nitrile rubber, styrene/butadiene rubber, butadiene rubber, isoprene rubber, ethylene propylene diene rubber, acrylic rubber, or isobutene/isoprene rubber. etc., and these rubbers can be used singly or in combination.

In addition, the elastic material of the bag 120 may contain additives such as vulcanizing agents, fillers, softening agents, coloring agents, or anti-degradation agents. As the vulcanizing agent, sulfur, sulfur compounds, peroxides, or the like can be used. Barium sulfate, calcium carbonate, silicic acid, magnesium silicate, calcium silicate, or the like can be used as the filler. A paraffinic process oil, a naphthenic process oil, or the like can be used as the softening agent. As a coloring agent, carbon black, titanium white, ultramarine blue, phthalocyanine, red iron oxide, lead chromate, or the like can be used. Phenol, wax, or the like can be used as the anti-deterioration agent.

Bag 120 is preferably colored. By being colored, the bag body 120 can not only insulate sound between the first translucent panel 110 side and the second translucent panel 112 side, but also have a light shielding property and a visibility property. . Alternatively, the bag 120 may not be completely opaque. That is, the bag 120 can be colored and transparent to achieve both translucency and opacity.

Further, the elastic material of bag 120 may contain a vulcanization aid or vulcanization accelerator. As a vulcanization aid, zinc stearate, stearic acid, zinc white, zinc oxide, magnesium oxide, or the like can be used. As a vulcanization accelerator, thiazoles, thiliums, sulfenamides, dithiocarbamates, or the like can be used.

The bag body 120 can also be made of a highly airtight flexible material other than the elastic material. In the case of a flexible material, the elastic force of the material itself is small, but the volume of the bag body 120 when inflated is designed to be large enough to close the opening 118 . By doing so, air is injected into the bag 120 to inflate it, and in the gap between the first translucent panel 110 and the second translucent panel 112, the first opening 114 and the second opening 114 are opened. The opening 118 in each of the sections can be closed. As a flexible material for the bag body 120, for example, vinyl chloride, polyethylene, polypropylene, or the like can be used.

As described above, according to the partition wall 10 according to the present embodiment, in the gap between the first light-transmitting panel 110 and the second light-transmitting panel 112, air is injected into the bag 120 or air is released from the bag 120. The sound insulation state or non-sound insulation state of the partition wall 10 can be adjusted by exhausting the air. Therefore, the partition wall 10 can suppress the manufacturing cost, and is easy to install because of its light weight. Inflated bag 120 also closes opening 118 of each of first opening 114 and second opening 116 . Therefore, the partition wall 10 can insulate sound between the first translucent panel 110 side and the second translucent panel 112 side, and is excellent in soundproofing.

The partition wall 10 according to this embodiment can be modified and modified in various ways. Several modifications of the partition wall 10 will be described below. In addition, in the following modifications, the description of the same configuration as that of the partition wall 10 described above will be omitted, and mainly the configuration different from that of the partition wall 10 will be described.

<Modification 1>
FIG. 3 is a schematic diagram of a partition wall 10A according to one embodiment of the present invention. Specifically, FIG. 3 is a schematic cross-sectional view of the partition wall 10A.

As shown in FIG. 3, the partition wall 10A includes a first translucent panel 110, a second translucent panel 112, and a bag body 120. As shown in FIG. First translucent panel 110 and second translucent panel 112 include first opening 114 and second opening 116, respectively. Each of the first opening 114 and the second opening 116 is provided with an opening 118 penetrating through the first translucent panel 110 or the second translucent panel 112 .

The bag 120 is attached with a first valve 140A-1 and a second valve 140A-2. The first valve 140A-1 is attached above the bag 120 and the second valve 140A-2 is attached below the bag 120. As shown in FIG.

Not air but liquid 125 is injected as a fluid into the bag 120 of the partition wall 10A. That is, the bag 120 can be inflated by being injected with liquid through the first valve 140A-1 or deflated by being discharged through the second valve 140A-2. Liquid 125 may be water or oil. Moreover, when the bag body 120 is transparent, the liquid 125 is preferably colored. By injecting the colored liquid 125 into the bag body 120, it is possible not only to insulate the sound between the first translucent panel 110 side and the second translucent panel 112 side, but also to shield the light.

The partition wall 10A can also be configured to have only the second valve 140A-2 without the first valve 140A-1. In this case, the liquid 125 is injected from the second valve 140A-2 and discharged from the second valve 140A-2.

In the partition wall 10A, the bag body 120 is lowered and expanded by the weight of the injected liquid 125 in the gap between the first translucent panel 110 and the second translucent panel 112. . Therefore, in the partition wall 10A, it is possible to adopt a configuration in which the elastic body 122 is not provided inside the bag body 120 .

Moreover, the partition wall 10A does not have to fill the entire inside of the bag 120 with the liquid 125 . For example, the liquid 125 can be injected to adjust the position of the bag 120, and air can be injected to inflate the bag 120 after adjustment.

As described above, according to the partition wall 10</b>A according to one embodiment of the present embodiment, the weight of the liquid 125 injected into the bag body 120 is used to overlap the bag body 120 with the first opening 114 and the second opening 116 . The bag body 120 can be inflated by the injected liquid 125 . Therefore, the partition wall 10A can suppress the manufacturing cost, and is lightweight and easy to install. Inflated bag 120 also closes opening 118 of each of first opening 114 and second opening 116 . Therefore, the partition wall 10A can insulate sound between the first translucent panel 110 side and the second translucent panel 112 side, and is excellent in soundproofing.

In addition, although the case where the liquid 125, that is, the fluid is injected into the bag body 120 in the modified example 1, it is also possible to use a fluid solid instead of the fluid.

<Modification 2>
FIG. 4 is a schematic diagram of a partition wall 10B according to one embodiment of the present invention. Specifically, FIGS. 4A and 4B are right side views of the partition wall 10B. and the second translucent panel 112 are shown in cross section.

As shown in FIG. 4, partition wall 10B includes first translucent panel 110, second translucent panel 112, bag body 120B, and shaft 150B. First translucent panel 110 and second translucent panel 112 include first opening 114 and second opening 116, respectively. Each of the first opening 114 and the second opening 116 is provided with an opening 118 penetrating through the first translucent panel 110 or the second translucent panel 112 .

The shaft 150B is provided above the partition wall 10B and can wind up the bag body 120B. That is, when there is no air inside the bag 120B, the shaft 150B can wind up and store the bag 120B. Therefore, the shaft 150B can also be configured to be rotated using the power source 152B.

In the partition wall 10B, a regulating valve is attached to the bag body 120B, and air can be injected into or discharged from the bag body 120B. Also, a regulating valve is attached to shaft 150B, and air can be inflated or discharged from bag body 120B via shaft 150B.

In the partition wall 10B, while injecting air into the bag 120B, the expansion force of the bag 120B is used to rotate the shaft 150B, and the gap between the first translucent panel 110 and the second translucent panel 112 is filled. An inflated bag 120B can be inserted therein. In addition, the shaft 150B is rotated to insert the bag 120 into which no air is injected into the gap between the first translucent panel 110 and the second translucent panel 112, thereby injecting air into the bag 120B. It can also be inflated by pressing (FIG. 4(B)).

When inserting the bag body 120B into the gap between the first translucent panel 110 and the second translucent panel 112, a wire 154B can also be used as shown in FIG. 4(A). That is, the wire 154B may be attached to the tip of the bag 120B and the wire 154B may be pulled. Since the wire 154B can reduce the problem of the bag 120B getting caught in the gap, the bag 120B can be reliably overlapped with the first opening 114 and the second opening 116. become.

The means for winding up the bag body 120B shown in FIG. 4 uses one shaft 150B and rotates the shaft 150B, but the means for winding up the bag body 120B is not limited to this. It is also possible to provide two fixed shafts in the height direction of the partition wall 10 and wind the bags 120B around these. If the bag body 120B is wound around a single shaft, the bag body 120B thus wound up becomes thicker, so a large storage space for the bag body 120B must be secured. On the other hand, when the bag body 120B is wound around two fixed shafts provided in the height direction of the partition wall 10, the bag body 120 can be accommodated using the distance between the two fixed shafts. The thickness of the bag body 120B can be reduced.
