Mode for Carrying Out the Invention

[0010] FIGS. 1 to 8 show one exemplary form of the soundproof room of the present invention. The soundproof room 11 is formed by a housing 12 and a door 13 as shown in FIGS. 1 to 7, has a space where people can enter, and is installed in various places where people pass, such as inside a station building, an airport, a commercial facility, an exhibition hall, an outdoor square, the inside of a store, a hotel, an apartment building, or an office. Further, the soundproof room 11 can transmit and receive data to and from external devices via a network such as the Internet. A user who uses the soundproof room 11 can hold a video conference with a user who uses an external device having a video conferencing function, for example, using a video conferencing terminal installed in the soundproof room 11.

[0011] The housing 12 is made of members such as metal, wood, or resin, and is formed as a rectangular parallelepiped with a large height dimension as a whole. An opening for the user to enter and exit is provided on the front surface (FIG. 1), which is one side surface thereof. Further, casters 14 and adjusters 15 are respectively provided at the four corners of the bottom surface of the housing 12. The installer of the soundproof room 11 can move the soundproof room 11 to the installation location using the casters 14, and then fix the soundproof room 11 in a fixed position by adjusting the length of the adjuster 15 so that it is equal to the distance between the bottom surface of the soundproof room 11 and the floor surface.

[0012] An acoustic absorption material 12a is provided inside the housing 12, and voices spoken by the user inside the soundproof room 11 and voices emitted by the user using external equipment are less likely to leak outside the soundproof room 11. Therefore, even when the soundproof room 11 is installed in a public place where an unspecified number of people pass by, the user can talk about highly confidential content with confidence. Also, the specification of the floor material has a double floor structure in which a space is formed between the upper and lower floor boards by the intervention of a plurality of beams, and the strength required for people to enter and exit and support a sofa 16 and the like is ensured.

[0013] The door 13 is coupled to the housing 12 so as to be able to close the opening of the housing 12, and is configured to be openable and closable about the coupling portion with the housing 12 by operating the handle 13a. A door glass 13b is provided on the door 13, and it is possible to visually recognize the inside of the soundproof room 11 from the outside.

[0014] A lock (not shown) is provided between the housing 12 and the door 13, and by the control of a control unit (CPU) incorporated in the housing 12, a unlocked state in which the door 13 can be opened and a locked state in which the door 13 cannot be opened are switched. The lock is controlled to unlock or lock the soundproof room 11 by the user operating from the inside of the housing 12 to switch between the unlocked state and the locked state, or by remote operation.

[0015] On the front side of the housing 12, an operation reception unit 17 for receiving user operations is provided. The operation reception unit 17 is, for example, a display with a touch panel, and receives the planned usage time input by the user. The user can select, for example, one of the planned usage times of 30 minutes, 60 minutes, or 90 minutes. The fee to be paid is determined according to the planned usage time, and power supply to the electronic devices provided inside the soundproof room 11 is started after the payment is completed until the planned usage time elapses.

[0016] The electronic devices include permanently installed video conferencing equipment 18, lighting 19 installed on the ceiling 12b of the housing 12, a surveillance camera 20, a speaker 21, air conditioning equipment, and a computer or mobile terminal brought in by the user, etc. The air conditioning equipment ventilates the internal space of the soundproof room and adjusts the internal temperature. For example, it includes a fan 22 that can suck indoor air and discharge it outside. The fan 22 forms an upward airflow by its operation, causing the indoor air to flow from the floor to the ceiling.

[0017] The air conditioning equipment operates based on the control by the control unit from when the payment is completed until the planned usage time elapses. These electronic devices are, for example, powered through a power plug from a power outlet provided indoors or outdoors. Also, the user can use the connection port 23 of the electronic devices provided indoors as needed.

[0018] By the way, from the perspective of disaster prevention, non-combustible materials are used for the sound-absorbing material 12a on the inner wall surface and the tile material 12c laid on the floor surface in the soundproof room 11. However, usually, when a new space surrounded by walls, etc. is newly configured inside a building, additional disaster prevention facilities may be required depending on the degree of airtightness. For such reasons, an automatic fire extinguishing device 24 is provided on the ceiling 12b of the soundproof room 11 to detect abnormalities early and minimize damage in case of a fire indoors.

[0019] The automatic fire extinguishing device 24 is a downward discharge type fire extinguishing device (sprinkler). As shown in FIG. 8, it integrally includes a fire extinguishing agent container 25 filled with a fire extinguishing agent, and a discharge nozzle 26 provided at the center of the lower end of the fire extinguishing agent container 25, which can discharge the fire extinguishing agent into the room upon receiving the detection of a built-in heat sensing part (not shown). Further, on both sides of the discharge nozzle 26, a pressure filling port 27 is attached to one side, and a pressure gauge 28 is attached to the other side. A low melting point metal is used for the heat sensing part. When the heat collecting plate 26a at the lower end of the discharge nozzle 26 senses the heat from the fire source, the low melting point metal melts, and the pressurized gas in the container blows off the sealing plug and the heat collecting plate 26a, starting the discharge of the fire extinguishing agent.

[0020] Here, the mounting position of the automatic fire extinguishing device 24 is set in consideration of the arrangements of the lighting 19, the speaker 21, the fan 22, various cover members 29, etc. so as not to lose the functionality of the soundproof room 11 (FIG. 3). In particular, the position of the discharge nozzle 26, that is, the position of the heat detection part and the position of the fan 22 are provided in a side-by-side relationship with each other so that the upward airflow formed by the operation of the fan 22 promotes the upward movement of the heat from the fire source. Also, as shown in FIGS. 4 and 6, by arranging the discharge nozzle 26 at the height position of the ceiling 12b, that is, corresponding to the opening 12d position of the ceiling 12b, the fire extinguishing agent container 25 is provided outside the ceiling 12b. The fire extinguishing agent container 25 is covered by a box-shaped fire extinguishing device cover 30, and the fire extinguishing agent container 25 is detachable with respect to the mounting part 31 provided on the upper plate 30a of the fire extinguishing device cover 30.

[0021] The mounting part 31 is a pair of fixing brackets having mating surfaces that contact in the vertical direction. The upper bracket 31a is fixed to the lower surface of the upper plate 30a, and the lower bracket 31b is fixed to the upper surface of the fire extinguishing agent container 25. Thereby, by inserting the hook 31c of the lower bracket 31b into the engagement hole provided in the mating surface of the upper bracket 31a and rotating the fire extinguishing agent container 25 horizontally with respect to the fire extinguishing device cover 30, the hook 31c engages with the upper bracket 31a, and the automatic fire extinguishing device 24 is fixed in the fire extinguishing device cover 30.

[0022] The fire extinguishing device cover 30 is provided at a position retracted inward with respect to the position of the outer wall surface of the housing 12 (Fig. 3). The height dimension of the fire extinguishing device cover 30 is formed to be as small as possible so that the discharge nozzle 26 aligns with the height position of the ceiling 12b of the soundproof chamber 11 in a state where the automatic fire extinguishing device 24 is fixed to the upper plate 30a. On the other hand, the width dimension is also formed to be as small as possible so as to correspond to the outer diameter dimension of the fire extinguishing agent container 25.

[0023] In this way, since the soundproof chamber 11 is provided with the integrated automatic fire extinguishing device 24 including the fire extinguishing agent container 25 on the ceiling 12b, the initial fire can be quickly suppressed without relying on human operation. Moreover, since the fan 22 provided at the same height position as the automatic fire extinguishing device 24 on the ceiling 12b forms an upward airflow in the soundproof chamber 11 by its operation, the rise of heat from the fire source is promoted, enabling quick and reliable heat detection.

[0024] Also, since the soundproof chamber 11 can be transported with the automatic fire extinguishing device 24 provided on the ceiling 12b, it can be immediately put into use without any work required for the installation of the soundproof chamber 11. That is, a structure of the soundproof chamber 11 that can exhibit excellent disaster prevention functions in an emergency while facilitating installation is obtained, and thus, the safe use of the soundproof chamber 11 can be promoted in various environments where it is installed.

[0025] Furthermore, since the fire extinguishing agent container 25 is provided outside the ceiling 12b by arranging the discharge nozzle 26 provided in the automatic fire extinguishing device 24 corresponding to the height position of the ceiling 12b, the space utilization efficiency in the soundproof chamber 11 can be increased. Moreover, in combination with the integrated structure of the automatic fire extinguishing device 24, the fire extinguishing device cover 30 can be formed small, so that the aesthetic appearance of the soundproof chamber 11 is not impaired, and the inconvenience of an increase in thickness across the entire ceiling 12b is eliminated.

[0026] In addition, since the fire extinguishing device cover 30 is provided with an attachment portion 31 to which the fire extinguishing agent container 25 can be detachably attached, the automatic fire extinguishing device 24 can be stably held at the ceiling 12b position. Moreover, since the attachment portion 31 is a pair of fixing brackets having mating surfaces that abut in the vertical direction, even if there are restrictions on the attachment space, the attachment and detachment can be easily performed.

[0027] Also, since the fire extinguishing device cover 30 is provided at a position retracted inward with respect to the outer wall surface of the housing 12, there is no risk of contact with other structures when installing the soundproof room 11. In particular, even in a situation where the soundproof room 11 has to pass through in an inclined state, such as in a narrow building width area, the position of the fire extinguishing device cover 30 can be kept low for safe and rapid transportation.

[0028] Furthermore, as described above, the reliability of the automatic fire extinguishing device 24 can be improved by the fan 22 provided on the ceiling 12b of the soundproof room 11. In addition to this, since the external person can recognize the occurrence of a fire in the soundproof room 11 due to the smoke discharged from the fan 22, it enables a quick and accurate response required as the initial action in an emergency.

[0029] Note that the present invention is not limited to the above-described embodiment. The soundproof room can be provided with various facilities necessary for disaster prevention in addition to the fire extinguishing facilities, and the installation location may be a moving body such as a railway vehicle, a bus, a taxi, or an airplane. Also, the shape of the housing is not limited to a rectangular parallelepiped, and may be a cylindrical shape, and a space capable of accommodating not only one person but also two or more people can be formed without impairing the advantages of a mobile and portable soundproof room. Furthermore, if the automatic fire extinguishing device has a compact integrated configuration provided on the ceiling, it can be appropriately changed in terms of specifications, mounting position, etc. In addition, the shapes of the fire extinguishing device cover and the attachment portion are also arbitrary, and the opening on the ceiling surface where the discharge nozzle is located may be covered with a decorative panel or the like. Also, the fan is provided on the ceiling surface, that is, on the same surface as the surface where the automatic fire extinguishing device is mounted, to achieve a remarkable effect, but it is not limited to this, and it can be appropriately changed according to the environment where the soundproof room is installed, such as being provided at the upper part of the side wall surface.
