1 is a front view of a soundproof room showing an embodiment of the present invention; This is also a side view. FIG. FIG. 4 is a cross-sectional view taken along line IV-IV of FIG. This is a cross-sectional view taken along line VV of Figure 1. FIG. 6 is a cross-sectional view taken along the line VI-VI of FIG. 7 is a cross-sectional view taken along line VII-VII of FIG. FIG.

Figures 1 to 8 show an example of a soundproof room of the present invention. As shown in Figures 1 to 7, the soundproof room 11 is formed by a housing 12 and a door 13, has a space that people can enter, and is installed in places where various people pass through, such as inside train stations, airports, commercial facilities, exhibition halls, outdoor plazas, inside stores, hotels, apartment buildings, or offices. The soundproof room 11 can also send and receive data to and from external devices via a network such as the Internet. A user using the soundproof room 11 can use a videoconferencing terminal installed in the soundproof room 11 to hold a videoconference with a user using an external device that has a videoconferencing function.

The housing 12 is made of materials such as metal, wood, or resin, and is formed as a rectangular parallelepiped with a large overall height dimension, with an opening for users to enter and exit on one side, the front (Figure 1). Casters 14 and adjusters 15 are provided on each of the four corners of the bottom surface of the housing 12. After using the casters 14 to move the soundproof room 11 to the installation location, the installer of the soundproof room 11 can fix the soundproof room 11 in a fixed position by adjusting the length of the adjusters 15 so that it is equal to the distance between the bottom surface of the soundproof room 11 and the floor surface.

A sound-absorbing material 12a is provided on the inside of the housing 12, so that voices spoken by users inside the soundproof room 11 and voices emitted by users using external devices are unlikely to leak out of the soundproof room 11. Therefore, even if the soundproof room 11 is installed in a public place where an unspecified number of people pass by, users can safely talk about highly confidential information. In addition, the flooring specifications have a double floor structure with multiple beams interposed to create spaces between the upper and lower floorboards, ensuring the strength necessary for people to enter and exit and for supporting sofas 16, etc.

The door 13 is connected to the housing 12 so that it can close the opening of the housing 12, and is configured to be able to be opened and closed around the joint with the housing 12 by operating the handle 13a. The door 13 is provided with door glass 13b, which allows the inside of the soundproof room 11 to be viewed from the outside.

A lock (not shown) is provided between the housing 12 and the door 13, and is switched between an unlocked state in which the door 13 can be opened and a locked state in which the door 13 cannot be opened under the control of a control unit (CPU) built into the housing 12. The lock is controlled to unlock or lock the soundproof room 11 by switching between the unlocked and closed states by a user operating it from inside the housing 12, or by switching it by remote control.

In addition, an operation reception unit 17 that receives user operations is provided on the front side of the housing 12. 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 one of the planned usage times, for example, 30 minutes, 60 minutes, or 90 minutes. The fee to be paid is determined according to the planned usage time, and power supply to electronic devices installed inside the soundproof room 11 is started from the time the payment is completed until the planned usage time has elapsed.

The electronic devices include permanently installed videoconferencing equipment 18, lighting 19 installed on the ceiling 12b of the housing 12, security cameras 20, speakers 21, air conditioning equipment, and computers or mobile terminals brought in by users. The air conditioning equipment ventilates the interior space of the soundproof room and adjusts the internal temperature, and includes, for example, a fan 22 that can suck in air from the room and release it to the outside. When activated, the fan 22 creates an updraft, directing the air in the room from the floor to the ceiling.

The air conditioning equipment operates under the control of the control unit from the completion of payment until the scheduled usage time has elapsed. These electronic devices are configured to receive power from a power outlet installed indoors or outdoors via a power plug. In addition, the user can use the connection port 23 of the electronic device installed in the room as necessary.

In the soundproof room 11, non-flammable sound-absorbing material 12a on the inner walls and tile material 12c on the floor are used from a disaster prevention perspective. However, when a new space surrounded by walls is constructed inside a building, additional disaster prevention equipment may need to be installed depending on the level of sealing. For this reason, an automatic fire extinguishing device 24 is installed on the ceiling 12b of the soundproof room 11 to detect abnormalities early in the event of a fire inside the room and minimize damage.

The automatic fire extinguishing device 24 is a downward-discharge type fire extinguishing device (sprinkler), and as shown in FIG. 8, is integrally equipped with an extinguishing agent container 25 filled with extinguishing agent, and a discharge nozzle 26 that is provided at the center of the lower end of the extinguishing agent container 25 and can discharge the extinguishing agent into the room upon detection by a built-in heat detector (not shown). A pressure filling port 27 is attached to one side of the discharge nozzle 26, and a pressure gauge (gauge) 28 is attached to the other side. A low-melting point metal is used for the heat detector, and when the heat collecting plate 26a at the lower end of the discharge nozzle 26 detects 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 extinguishing agent.

The automatic fire extinguishing device 24 is installed in a position that takes into consideration the arrangement of the lighting 19, speaker 21, fan 22, and various cover members 29 so as not to lose the functionality of the soundproof room 11 (Fig. 3). In particular, the position of the discharge nozzle 26, i.e., the position of the heat detection unit and the position of the fan 22, are arranged in a side-by-side relationship so that the rising air current formed by the operation of the fan 22 promotes the rise of heat from the fire source. As shown in Figs. 4 and 6, the discharge nozzle 26 is arranged at the height of the ceiling 12b, i.e., corresponding to the position of the opening 12d of the ceiling 12b, so that the extinguishing agent container 25 is installed outside the ceiling 12b. The extinguishing agent container 25 is covered by a box-shaped fire extinguishing device cover 30, and the extinguishing agent container 25 is detachable from the mounting portion 31 provided on the upper plate 30a of the fire extinguishing device cover 30.

The mounting portion 31 is a pair of fixing brackets with mating surfaces that abut in the vertical direction, with the upper bracket 31a fixed to the lower surface of the upper plate 30a and the lower bracket 31b fixed to the upper surface of the extinguishant container 25. As a result, by inserting the hook 31c of the lower bracket 31b into an engagement hole provided in the mating surface of the upper bracket 31a and rotating the extinguishant container 25 horizontally relative to the fire extinguisher cover 30, the hook 31c engages with the upper bracket 31a, and the automatic fire extinguisher 24 is fixed inside the fire extinguisher cover 30.

The fire extinguisher cover 30 is set in a position retracted inward from the position of the outer wall surface of the housing 12 (Figure 3). The height dimension of the fire extinguisher cover 30 is made as small as possible so that the discharge nozzle 26 is aligned with the height position of the ceiling 12b of the soundproof room 11 when the automatic fire extinguisher 24 is fixed to the upper plate 30a. On the other hand, the width dimension is also made as small as possible so as to correspond to the outer diameter dimension of the fire extinguishant container 25.

In this way, the soundproof room 11 is equipped with an integrated automatic fire extinguishing device 24 including a fire extinguishing agent container 25 on the ceiling 12b, so that an initial fire can be quickly put out without relying on human operation. Furthermore, the fan 22 installed on the ceiling 12b at the same height as the automatic fire extinguishing device 24 creates an updraft within the soundproof room 11 when activated, which promotes the rise of heat from the fire source and enables quick and reliable heat detection.

In addition, since the soundproof room 11 can be transported with the automatic fire extinguishing device 24 still installed on the ceiling 12b, it can be immediately used without the need for any construction work associated with the installation of the soundproof room 11. In other words, a structure for the soundproof room 11 that is easy to install and can provide excellent disaster prevention capabilities in the event of an emergency can be obtained, thereby promoting the safe use of the soundproof room 11 in the various environments in which it is installed.

Furthermore, by positioning the discharge nozzle 26 of the automatic fire extinguishing device 24 at a height position corresponding to the ceiling 12b, the extinguishing agent container 25 is provided on the outside of the ceiling 12b, which improves the space utilization efficiency within the soundproof room 11. Moreover, combined with the integrated structure of the automatic fire extinguishing device 24, the fire extinguishing device cover 30 can be made small, so the aesthetic appearance of the soundproof room 11 is not marred and the inconvenience of an increased thickness over the entire ceiling 12b is eliminated.

In addition, the extinguisher cover 30 is provided with a mounting portion 31 to which the extinguishant container 25 can be attached and detached, so that the automatic fire extinguisher 24 can be stably held at the ceiling 12b position. Moreover, because the mounting portion 31 is a pair of fixing brackets with mating surfaces that abut in the vertical direction, it can be easily attached and detached even if the installation space is limited.

In addition, because the fire extinguisher cover 30 is set inward relative to the position of the outer wall surface of the housing 12, there is no risk of it coming into contact with other structures when installing the soundproof room 11. In particular, even in situations where the soundproof room 11 must be passed through at an angle, such as in places with a narrow entrance inside a building, the position of the fire extinguisher cover 30 can be kept low, allowing for safe and rapid transportation.

Furthermore, as described above, the reliability of the automatic fire extinguishing device 24 can be improved by the fan 22 installed on the ceiling 12b of the soundproof room 11, but in addition to this, the smoke discharged from the fan 22 allows people outside to become aware of the occurrence of a fire inside the soundproof room 11, making it possible to respond quickly and accurately as an initial response in the event of an emergency.

The present invention is not limited to the above-mentioned embodiment, and the soundproof room may be equipped with various equipment necessary for disaster prevention in addition to the fire extinguishing equipment, and the installation location may be a moving body such as a railway car, bus, taxi, or airplane. The shape of the housing is not limited to a rectangular parallelepiped, but may be a cylindrical shape, and the room may be formed with a space that can accommodate not only one person but also two or more people, as long as the advantages of the mobile portable soundproof room are not lost. Furthermore, the specifications and installation position of the automatic fire extinguishing device can be appropriately changed as long as it is a compact, integrated device installed on the ceiling. In addition, the shape of the fire extinguishing device cover and the installation part can be arbitrary, and the opening on the ceiling surface where the discharge nozzle is located can be covered with a decorative panel or the like. Furthermore, the fan is most effective when installed on the ceiling surface, that is, on the same surface as the surface on which the automatic fire extinguishing device is installed, but this is not limited, and it can be appropriately changed, such as by installing it on the upper part of the side wall surface depending on the environment in which the soundproof room is installed.
