[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-28995 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional method, the hinge is located on the opposite side of the sleeve panel when opening and closing the door, so the wiring between the control panel and the electric lock has to make a long U-turn near the hinge, and furthermore, the wiring has to be routed through the inside of the door, which reduces the workability of assembling and maintaining the soundproof room.

[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a soundproof room that can improve the workability of assembly and maintenance. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the soundproof room of the present invention is a portable soundproof room comprising a housing in which an office space that users can enter and exit through an entrance / exit is formed, a door frame provided at the entrance / exit, a door that is attached to the door frame so that it can be opened and closed via a hinge, an electric lock that can lock and unlock the door, a control panel that controls the operation of the electric lock, and a thumb turn that can manually switch the locking and unlocking states of the electric lock, wherein the housing has a sleeve panel that is provided alongside the door frame, and the sleeve panel consists of an outer sleeve panel and an inner sleeve panel, and the space provided between the inner and outer sleeve panels accommodates the electric lock, the control panel, and wiring between the control panel and the electric lock, and the electric lock has a locking member that moves forward and backward relative to a locking hole in a receiving bracket provided on the door.

[0007] The door frame is also characterized in that the inner sleeve panel is divided into an upper inner sleeve panel and a lower inner sleeve panel at a height corresponding to the position of the electric lock, and the lower inner sleeve panel has a hole for connecting the thumb turn to the electric lock. Furthermore, the upper inner sleeve panel is characterized in that it rotates in a direction away from the door frame to open. [Effects of the Invention]

[0008] The soundproof room of the present invention allows the wiring between the control panel and the electric lock to be short and without passing through the inside of the door, improving the workability of assembling and maintaining the soundproof room. In particular, the wiring has no moving parts, making it less likely to break, and is advantageous in terms of durability and cost. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] 1 to 8 show an embodiment of the present invention. As shown in FIGS. 1 to 7, soundproof room 11 is formed by a housing 12 and a door 13 and has an office space where a user can enter and work. It is installed in places where various people pass through, such as train stations, airports, commercial facilities, exhibition halls, outdoor plazas, store interiors, hotels, apartment buildings, or offices. Soundproof room 11 can also transmit and receive data to and from external devices via a network such as the Internet. A user using soundproof room 11 can use a videoconferencing terminal installed in soundproof room 11 to hold a videoconference with a user using an external device with a videoconferencing function.

[0011] The housing 12 is made of materials such as metal, wood, or resin, and includes a floor 14, a ceiling 15, and four side walls (front wall 17, left side wall 18, right side wall 19, and rear wall 20) positioned on all four sides via support columns 16, forming a rectangular parallelepiped with a large height overall. The four side walls 17, 18, 19, and 20 have a hollow double-wall structure to enhance sound insulation. As shown in FIG. 7, the support columns 16 mainly include two paired pipes 16a standing on the floor 14 and covers 16b that align with the outer wall of the housing 12 to form chamfered corners. When the covers 16b are attached, the pipes 16a are concealed from the outside.

[0012] An entrance (opening) for users to enter and exit is formed on the front surface of the housing 12 (FIG. 1), and a door frame 21 is provided on the periphery of this entrance. In addition, a sleeve panel 22 is provided alongside the door frame 21 as a component constituting the front wall 17 of the housing 12.

[0013] Casters 23 are provided at the four corners of the bottom surface of the floor 14, with adjusters 24 provided near each. The installer of the soundproof room 11 can use the casters 23 to move the soundproof room 11 to the installation location, and then adjust the length of the adjusters 24 to fix the soundproof room 11 in place. Once installed, the soundproof room 11 can receive power via a power plug from a power outlet provided at the installation location. As shown in Figure 4, the ceiling 15 is provided with lighting 25, a ventilation fan 26, a speaker 27, an automatic fire extinguishing device 28, etc., which enhance the convenience and safety of the soundproof room 11.

[0014] A plurality of sound-absorbing materials 29 are provided inside the housing 12, making it difficult for voices spoken by users inside the soundproof room 11 and voices emitted by users using external devices to leak outside the soundproof room 11. Therefore, even if the soundproof room 11 is installed in a public place, users can safely discuss highly confidential information. The floor material 30 has the strength necessary for people to enter and exit and to support seats 31, floor-standing air conditioners 32, etc.

[0015] As shown in Fig. 7, the seat 31 is formed with a width sufficient for one adult to sit comfortably, with the backrest 31a positioned in contact with the inner wall of the right side wall 19 in the width direction of the housing 12 (the left-right direction in Fig. 7), and a table 33 that can be used while seated is attached in a cantilevered manner to the inner wall of the left side wall 18. The table 33 extends in the depth direction of the housing 12 (the up-down direction in Fig. 7), and a tray (accessory compartment) 34 is provided in a narrow space formed at a distance from the sleeve panel 22 in the depth direction. A light switch 35 and an outlet 36 are embedded in the table surface, allowing for comfortable use of information terminals such as personal computers and smartphones brought into the room.

[0016] The height, width, and depth dimensions of the office space are determined so that it does not obstruct users' entry and exit and does not impair the convenience of users working in the office when a set of seats 31 and tables 33 are arranged. As shown in Figure 7, the office space is divided into a table-side space 37 where the table 33 is arranged and a seat-side space 38 where the seat 31 is arranged, with the position of the table edge 33a as the boundary. Both spaces 37, 38 are basically obtained by dividing the office space into approximately two equal parts in the width direction.

[0017] As shown in Figure 1, the door frame 21 is made up of three frames: left and right vertical frames 39, 40 that extend vertically, and an upper frame 41 that is connected to the upper ends of the vertical frames 39, 40 and extends horizontally. The vertical frames 39, 40 are provided on both the left and right sides of the doorway, and the upper frame 41 is provided above the doorway, close to the ceiling 15. The door frame 21 has the necessary strength ensured by bent plate material or pipe material, and although not shown, it has various parts such as a door stop. In the following explanation, the left vertical frame when viewed from the front (outside the room) directly facing the doorway will be referred to as the left vertical frame 39, and the right vertical frame will be referred to as the right vertical frame 40.

[0018] The door 13 is a single-wing (outward-opening) door attached to the door frame 21 via a hinge 42 so as to be able to open and close. The door 13 is composed of a frame body 13b with handles 13a on both the inside and outside, and a glass panel 13c fitted into the frame body 13b. Although not shown, a typical door closer is attached to the door 13 to improve user convenience when opening and closing the door. In this embodiment, the hinge 42 is attached to the right vertical frame 40, and the door 13 is used as a right-opening door 13. As a result, one side of the left vertical frame 39 is aligned with the free end of the door 13 (the side opposite the hinge 42) in the closed state, and the other side opposite the door 13 is aligned with one side of the sleeve panel 22 (FIG. 1).

[0019] The door 13 is also locked and managed by an electric lock 43. The electric lock 43 receives an operation command from a control panel 44 and switches between an unlocked state in which the door 13 can be opened and a locked state in which the door 13 cannot be opened. In this embodiment, an electric lock 43 called AL3M (deadlocking motor lock) manufactured by Miwa Lock Co., Ltd. and a corresponding strike metal fitting (strike) 45 are used, and their structures can be referenced.

[0020] In addition to electrical operation, the door 13 can be locked and unlocked by operating either the attached key cylinder 46 or thumb turn 47. These parts 46, 47 have a well-known structure that allows the locked and unlocked states of the electric lock 43 to be manually switched, and their length (axis length) is selected taking into account the thickness of the sleeve panel 22.

[0021] The sleeve panel 22 is made up of an outer sleeve panel 48 (Fig. 1) and an inner sleeve panel 49 (Fig. 6) arranged facing each other in the thickness direction, and as can be seen from Fig. 7, an internal space is formed by leaving a gap between the inner and outer sleeve panels 48, 49. The internal space of the sleeve panel 22 has a width dimension corresponding to the distance between the left support column 16 and the left vertical frame 39, a height dimension corresponding to the distance between the floor 14 and the ceiling 15, and a depth dimension corresponding to the distance between the outer sleeve panel 48 and the inner sleeve panel 49.

[0022] The interior space of the sleeve panel 22 is provided with a wiring space 51 (the area surrounded by a thick line in FIG. 8) for wiring the electric wires (cables) 50 between the control panel 44 and the electric lock 43. The wiring space 51 has an area large enough to accommodate the placement of the devices required for locking management (details will be described later). This area corresponds to the upper space (upper half space) of the interior space of the sleeve panel 22, which is divided into two parts, top and bottom, corresponding to the placement of the electric lock 43.

[0023] As shown in Figures 6 to 8, the electric lock 43 is incorporated into the sleeve panel 22 together with the control panel 44, with the thumb turn 47 positioned and connected in the table-side space 37. That is, the electric lock 43 has the mounting base 53 of the lock case 52 attached to the opening of the left vertical frame 39, so that the lock case 52 and electric wires 50 are positioned between the inner and outer sleeve panels 48, 49. Here, the electric lock 43, in which the key cylinder 46 and thumb turn 47 are coaxially connected, has the thumb turn 47 positioned slightly above the height of the table surface of the table 33 (see also Figure 5), making it convenient for the user to open the door from inside the room.

[0024] As shown in Fig. 8, the electric lock 43 incorporated in the sleeve panel 22 has a receiving bracket 45 attached to the free end of the door 13. The driving force of a drive motor built into the lock case 52 advances a locking member (deadbolt) 54 toward a locking hole 45a in the receiving bracket 45, relative to the mounting seat 53 (as shown in Fig. 8). When locked, the locking member 54 protruding from the mounting seat 53 of the lock case 52 is engaged with the receiving bracket 45. When unlocked, the locking member 54 begins to retract into the lock case 52, and when fully unlocked, the tip surface of the locking member 54 is positioned on the outer surface of the mounting seat 53. In this case, a gap L between the outer surfaces of the mounting seat 53 and the receiving bracket 45 is secured, for example, to about 5 to 10 mm, taking into consideration the engagement of the locking member 54 when locked and the opening and closing movement of the door 13 when unlocked.

[0025] The control panel 44 is equipped with a drive circuit that controls the power supply to the drive motor according to the state of the electric lock 43, a communication circuit, and a touch-panel display 55 that accepts user operations. It is attached to a flat bracket 56 and is located above the electric lock 43 (Figure 1). The communication circuit is connected to an antenna 57, and wireless communication is performed with a management device (server) on the network, using a communication standard such as LTE. The display 55 accepts the planned usage time in 15-minute increments for immediate reservations. Such reservations can be made via a management site that allows advance reservations, allowing the date and time to be specified from an information terminal such as a smartphone.

[0026] When the reserved time arrives, the user either has the QR code (registered trademark) displayed on the terminal screen read by the QR code reader 58, or, in the case of an immediate reservation, performs the reservation operation on the display 55 and then has the IC reader 59 read a card (payment method) such as a credit card or electronic money card. Then, the control box 60 acquires the payment information from the various cards and executes the payment process by communicating with a payment server on the network via the antenna 61.

[0027] Once the necessary authentication is completed in the management device, the control panel 44 sends an unlock signal to the electric lock 43, unlocking the door 13 and allowing entry. The fee to be paid is determined according to the scheduled time of use, and the user can use the soundproof room 11 from the time payment is completed until the scheduled time has elapsed. Furthermore, once a user enters the room, the usage status can be confirmed from outside via the presence indicator light 62, and as the reserved time approaches the end, a voice prompting the user to leave is emitted from the speaker 27. In this way, user convenience is improved and the operation of the soundproof room 11 becomes safe and reliable.

[0028] Various devices including the control panel 44, along with antennas 57, 61, etc., are connected to a wiring device (e.g., a power distribution box) 63 installed on the ceiling 15 to receive power (Fig. 8). For example, external terminals such as a display 55, a QR code reader 58, and an IC reader 59 are collectively arranged on the sleeve panel 22 for ease of use, and are specifically attached to a mounting portion (opening) of the outer sleeve panel 48 at a position slightly higher than the electric lock 43. The payment control box 60 is also installed in the interior space of the sleeve panel 22, similar to the control panel 44, but is installed at a relatively high position in consideration of the placement of other devices (Fig. 1).

[0029] Incidentally, when adjusting or repairing (replacing) equipment installed inside the sleeve panel 22, such as the control panel 44, it is necessary to temporarily open the concealed wiring space 51 to access it. However, detaching and attaching the thumb turn 47 each time such maintenance is performed makes the work cumbersome. Moreover, removing the inner sleeve panel 49 requires the removal of the seat 31 and forces the worker to assume an uncomfortable position under the table 33, which places a heavy physical burden on the worker.

[0030] Therefore, as shown in Figure 6, the inner sleeve panel 49 is divided into an upper inner sleeve panel 64 and a lower inner sleeve panel 65 at a height position (horizontal plane) S corresponding to the position of the electric lock 43. In this embodiment, the upper and lower division position S is located slightly above the upper end (electric wire connection portion) of the electric lock 43, but it may also be located below that (in a range overlapping with the electric lock 43).

[0031] The upper inner sleeve panel 64 is configured to rotate around a hinge (not shown) provided on the pipe material 16a of the support column 16 in a direction (indicated by the arrow in Figure 7) away from the door frame 21 (left vertical frame 39), in other words, in a direction away from the operator, to open. Note that if screws are used as the fixing means, the upper inner sleeve panel 64 is detachable. In this case, the space above the table 33 can be used as a space (work space) for attaching and detaching the upper inner sleeve panel 64.

[0032] The upper inner sleeve panel 64 has an opening angle of, for example, 70 degrees, with its free end positioned at point P in the table-side space 37 in a plan view (Fig. 7), widening the wiring space 51. In other words, the various devices 44, 58, 59, 60 inside the sleeve panel 22 are exposed to the interior of the room along with their electrical wires. In addition, as shown in Fig. 6, the upper and lower ends of the upper inner sleeve panel 64 are provided with a pair of cam locks 67, one above the other, which are released from the cam lock when unlocked, allowing the upper inner sleeve panel 64 to be opened.

[0033] The lower inner sleeve panel 65 has a hole 66 for connecting the thumb turn 47 to the electric lock 43 (Fig. 6), and when installed, the electric lock 43 (the entire lock case 52) is placed on the backside. With this configuration, when performing maintenance on the control panel 44, it is possible to simply open the upper inner sleeve panel 64 and access the wiring space 51 without having to disassemble the electric lock 43 (unfastening screws or pins). On the other hand, when performing maintenance on the electric lock 43, by accessing the wiring space 51 in advance and disconnecting the connector 50a (Fig. 8), the electric wires 50 can be easily handled when removing the lock case 52 from the opening in the left vertical frame 39 (the same applies when assembling, which is the reverse procedure).

[0034] Thus, with the soundproof room 11 of the present invention, the wiring between the control panel 44 and the electric lock 43 can be short and can be routed without passing through the inside of the door 13, improving the workability of assembling and maintaining the soundproof room 11. In particular, the wiring has no moving parts, making it less likely to break, and is advantageous in terms of durability and cost.

[0035] Furthermore, when access to the wiring space 51 is required, all that is required is to move the upper inner sleeve panel 64, which does not affect the connection state of the thumb turn 47, further improving the ease of maintenance work. Furthermore, the wiring space 51 can be accessed instantly by the simple operation of simply opening the upper inner sleeve panel 64. In particular, no adjustments are required to the tables 33 and seats 31, and these can be used in their operational state to ensure a good working posture, resulting in a soundproof room that is both safe and easy to handle.

[0036] The present invention is not limited to the above-described exemplary embodiments, and the structure of the housing and doors, the selection and placement of devices and items, and the locking management method can be modified as appropriate depending on the specifications of the soundproof room. For example, the inside of the sleeve panel may be configured to incorporate an electric lock and its control panel, and the placement of various devices in the wiring space and the routing of various electrical wires, including the electric lock wires, are optional. Furthermore, the inner sleeve panel may be configured to open the wiring space, and the division positions and number of divisions may be optional. For example, the panel body may be fixed, and a separate, openable maintenance door may be provided. [Explanation of symbols]
