Summary of the Invention

Problems to be Solved by the Invention

[0004] When a temperature difference occurs between two spaces (for example, outdoors and indoors) separated by a fitting such as an automatic door device, dew condensation may occur on the surfaces of a fixed door, a movable door, a guard screen, etc., which constitute the fitting such as the automatic door device. In a fitting such as an automatic door device in which a display surface for displaying an image of a display device is installed in a direction facing the above surface, the visibility of the image may be reduced due to dew condensation. Patent Document 1 does not disclose a specific configuration method of a glass door having an information display function.

[0005] In view of the above problems, an object of the present invention is to provide a technique capable of suppressing the occurrence of dew condensation on the display surface side of a display device installed in a fitting such as an automatic door device.

Means for Solving the Problems

[0006] In order to solve the above problems, an automatic door device according to an aspect of the present invention includes a fixed door that closes a part of an opening, a movable door that is provided in the opening and is controlled to open and close, and a guard screen that is provided to face the fixed door with the movable door in the open state interposed therebetween.

Embodiments for Carrying Out the Invention

[0012] Among the embodiments disclosed in this specification, those composed of a plurality of objects may integrate the plurality of objects, and conversely, those composed of one object can be divided into a plurality of objects. Whether integrated or not, it only needs to be configured to achieve the object of the invention.

[0013] Among the embodiments disclosed in this specification, those in which a plurality of functions are provided in a distributed manner may provide some or all of the plurality of functions in an aggregated manner, and conversely, those in which a plurality of functions are provided in an aggregated manner can be provided such that some or all of the plurality of functions are distributed. Whether the functions are aggregated or distributed, it only needs to be configured to achieve the object of the invention.

[0014] In addition, for separate components with something in common, they are distinguished by attaching "first", "second", etc. at the beginning of the name, and these are omitted when collectively referring to them. Also, terms including ordinal numbers such as first and second are used to describe various components, but this term is only used for the purpose of distinguishing one component from another component, and the components are not limited by this term.

[0015] An automatic door device according to an aspect of the present invention includes a display device and a partitioning member. The display device is installed such that a display surface for displaying an image faces any one of the surfaces of a fixed door that closes a part of an opening, a movable door provided in the opening and controlled to open and close, and a guard screen provided to face the fixed door with the movable door in an open state interposed therebetween. The partitioning member partitions a space that is dehumidified by a drying material and includes at least the space between the display surface and any one of the surfaces of the fixed door, the movable door, and the guard screen.

[0016] According to this configuration, the space facing the display surface is partitioned. Also, this space is dehumidified by a drying material. Therefore, it is possible to prevent the occurrence of dew condensation on the display surface and surfaces such as the fixed door facing the display surface, and suppress the deterioration of the visibility of the image due to dew condensation.

[0017] As an example, the partitioning member is a joining member that joins the surface and a frame surrounding the outer periphery of the display device. Therefore, since the surface and the frame are joined across the outer periphery of the display surface, it is possible to prevent foreign matters such as liquid and dust from the outside from entering between the display surface and the surface facing the display surface.

[0018] As an example, the partitioning member is provided so as to further block the gap between the display portion and the frame. Therefore, it is possible to form an internal space isolated from the outside only in the space between the surface and the display surface.

[0019] As an example, the display device further includes a back cover that covers the back surface, which is the surface on the side opposite to the side where the display surface is located. The partitioning member is the joining member and the back cover. Therefore, since the space from the space between the display surface of the display device and the surface such as a fixed door to the space between the back surface of the display device and the back cover can be partitioned as an internal space isolated from the outside, it is easier to construct than partitioning the internal space only by the space between the surface and the display surface.

[0020] As an example, the back cover is composed of a plurality of connected plate-like members. The partitioning member is provided so as to further block the gaps between the plurality of plate-like members. Therefore, even when creating a back cover by combining a plurality of plate-like members due to circumstances such as transportability, it is possible to partition an internal space isolated from the outside.

[0021] As an example, the display device is composed of a plurality of connected display panels. Each of the plurality of display panels includes a back cover that covers the back surface, which is the surface on the side opposite to the side where the display surface is located. The display device further includes a closing member that closes the gap between the back covers. The partitioning member is the joining member that joins the surface and a frame surrounding the outer periphery of the display device, the back cover, and the closing member.

[0022] At least one of the boundary portions between the plurality of display panels and the boundary portion between the display unit including the display surface and the frame body is provided with a communication hole that allows communication between the space on the display surface side and the space on the back side of the display device. Therefore, such a communication hole improves the air circulation between the space between the surface and the display surface and the space on the back side of the display device in the internal space isolated from the outside, and easily suppresses the increase in humidity.

[0023] As an example, the frame body includes a housing portion capable of housing the drying material. Therefore, the drying material can be housed at a position that does not obstruct the visual recognition of the image displayed on the display surface.

[0024] As an example, the frame body discharges water droplets from the surface to the outside of the space partitioned by the partitioning member. Therefore, even if condensation occurs in the internal space, the water droplets can be discharged to the outside of the internal space to eliminate the condensation.

[0025] As an example, the display device is installed on the fixed door or the guard screen. The frame body surrounding the outer periphery of the display device is arranged along a sash extending in the vertical direction and located at the end in the width direction of the fixed door or the guard screen. The display device further includes a base member that supports the frame body from below and a support member that supports the frame body from the side opposite to the side where the sash in the width direction is located. Therefore, in the vertical direction, the display device is stably supported because the base member supports the weight of the display device from below. In the horizontal direction, the display device is arranged along the sash on one side and supported by the support member on the other side, so that the horizontal shake is suppressed.

[0026] The support member includes a wiring housing portion capable of housing the wiring from the display device. Therefore, in addition to supporting the display device, the support member can house the wiring from the display device, preventing a complicated appearance.

[0027] The base member is arranged along the sash. Therefore, it is possible to prevent foreign matter from being pinched between the base member and the vertical frame when the movable door moves. In addition, the base member can be made inconspicuous, and the design quality is also improved.

[0028] A certain aspect of the fitting according to the present invention includes a display device and a partitioning member. The display device is installed such that a display surface for displaying an image faces any one of a fixed door that closes a part of the opening, a movable door that is provided in the opening and can be opened and closed, and a guard screen that is provided to face the fixed door with the open movable door interposed therebetween. The partitioning member partitions a space that is dehumidified by a drying material and includes at least the display surface and a space between the display surface and any one of the surfaces of the fixed door, the movable door, and the guard screen.

[0029] According to this configuration, the space facing the display surface is partitioned. Further, this space is dehumidified by a drying material. Therefore, it is possible to prevent condensation from occurring on the display surface and the surfaces such as the fixed door facing the display surface, and to suppress a decrease in the visibility of the image due to condensation.

[0030] A construction method of an automatic door device according to a certain aspect of the present invention includes a step of installing a display device such that a display surface for displaying an image faces any one of a fixed door that closes a part of the opening, a movable door that is provided in the opening and is controlled to open and close, and a guard screen that is provided to face the fixed door with the open movable door interposed therebetween, and a step of arranging a partitioning member so as to partition a space that is dehumidified by a drying material and includes at least the display surface and a space between the display surface and any one of the surfaces of the fixed door, the movable door, and the guard screen. According to this step, the space facing the display surface is partitioned. Further, this space is dehumidified by a drying material. Therefore, it is possible to prevent condensation from occurring on the display surface and the surfaces such as the fixed door facing the display surface, and to suppress a decrease in the visibility of the image due to condensation.

[0031] As an example, the installation method further includes a step of attaching a base member that supports the outer periphery of the display device from below, a step of arranging the frame along a sash that is located at an end in the width direction of the fixed door or the guard screen and extends in the vertical direction, and a step of attaching a support member that supports the frame from the side opposite to the side where the sash is located in the width direction. Therefore, in the vertical direction, the display device is stably supported because the weight of the display device is supported from below by the base member. In the horizontal direction, the display device is arranged along the sash on one side and supported by the support member on the other side, so that horizontal movement is suppressed.

[0032] Hereinafter, the present invention will be described with reference to the drawings based on preferred embodiments. In the embodiments and modification examples, the same or equivalent components and members are denoted by the same reference numerals, and repeated explanations will be omitted as appropriate. Also, the dimensions of the members in each drawing are appropriately enlarged or reduced for easy understanding. In addition, some of the members that are not important for explaining the embodiments are omitted from the drawings.

[0033] First, with reference to FIGS. 1 and 2, an outline of an automatic door device 100 as a fitting to which an embodiment of the present invention is applied will be described. FIG. 1 is a front view schematically showing the automatic door device 100 according to an embodiment of the present invention. The automatic door device 100 mainly includes a door unit 10 including a movable door that is controlled or driven to open and close, a controller 20 that controls the entire automatic door device 100, sensors 30 (collectively referred to as an activation sensor 31 and a protection sensor 32) that detect passersby, a door engine 40 that generates power, and a power transmission unit 50 that transmits the power to the door unit 10. In the following description, the left-right direction in FIG. 1 is defined as the horizontal direction, and the up-down direction in FIG. 1 is defined as the vertical direction. However, the automatic door device 100 can be installed in any posture, and its installation direction is not limited to the following examples. Here, the automatic door device 100 as a fitting will be described, but this embodiment is also applicable to fittings other than the automatic door device 100. In a fitting, the movable door only needs to be openable and closable, and for example, it may be opened and closed by the operation of the passerby himself / herself.

[0034] The door part 10 includes a first movable door 11L and a second movable door 11R that are each movably provided in the horizontal direction, and a first fixed door 12L and a second fixed door 12R as fixed parts that are provided at positions overlapping the first movable door 11L and the second movable door 11R when they are in the open state and block a part of the opening. The door part 10 also includes a guide mechanism 13 that guides the horizontal movement of the first movable door 11L and the second movable door 11R. The first movable door 11L, the second movable door 11R, the first fixed door 12L, and the second fixed door 12R are configured in a vertically long rectangular shape with a vertical dimension larger than the horizontal dimension. When the door part 10 is driven to open, the first movable door 11L shown on the left side in FIG. 1 is driven to the left, and the second movable door 11R shown on the right side in FIG. 1 is driven to the right. When the door part 10 is driven to close, conversely to the opening drive, the first movable door 11L is driven to the right, and the second movable door 11R is driven to the left. Note that the number and shape of the doors constituting the door part 10 are not limited to the above and can be appropriately designed according to the needs of the installation location. Similarly, the movable direction of the door part 10 is not limited to the horizontal direction and may be a direction inclined from the horizontal direction. Hereinafter, the first movable door 11L and the second movable door 11R may be collectively referred to as the movable door 11 without distinction. Similarly, the first fixed door 12L and the second fixed door 12R may be collectively referred to as the fixed door 12 without distinction.

[0035] The guide mechanism 13 includes a traveling rail 131, a door wheel 132, a guide rail 133, and a stabilizer 134. The traveling rail 131 is a columnar rail member that extends horizontally above the movable doors 11L and 11R over the entire movable range thereof. Two door wheels 132 are respectively provided on the upper parts of the movable doors 11L and 11R to suspend each movable door 11L and 11R on the traveling rail 131. When each movable door 11L and 11R is driven to open and close in the horizontal direction, the door wheel 132 rolls on the traveling rail 131, enabling a smooth opening and closing operation. The guide rail 133 is a groove-shaped rail member that extends horizontally below the movable doors 11L and 11R over the entire movable range thereof. The stabilizer 134 projects from the lower parts of the movable doors 11L and 11R and fits into the groove-shaped guide rail 133. When each movable door 11L and 11R is driven to open and close in the horizontal direction, the stabilizer 134 moves along the guide rail 133, so that vibrations in the expected direction (the direction perpendicular to the plane of FIG. 1) of each movable door 11L and 11R can be suppressed.

[0036] In addition, various parameters related to the opening and closing of the door unit 10 can be set by the controller 20. For example, the controller 20 can set the opening and closing speed, the opening and closing strength, the opening width, etc. The opening and closing speed is the horizontal speed of the first movable door 11L and the second movable door 11R, and the directions of the speeds of both doors are opposite to each other. It is preferable that the magnitudes (speeds) of the speeds of both doors are equal, but they may be different. Also, the opening and closing speed may be set to different values during normal opening and closing and at other times. For example, in the case of so-called reversal in which, during normal closing drive of the door unit 10, the drive is switched to opening drive to urgently avoid a passerby being pinched between the closing movable doors 11L and 11R, the speed of the movable doors 11L and 11R during that opening drive may be set to a value different from the speed during normal opening drive. Also, the opening speed and the closing speed when the door unit 10 is driven by temporary power supplied from a battery in an emergency such as a power failure when normal power is not available may be set to values different from those during normal drive.

[0037] The opening and closing strength is the magnitude of the force when the movable doors 11L and 11R are opened and closed, and is controlled by the torque value generated by the motor 42 described later. Similar to the above-mentioned opening and closing speed, it is preferably basically the same opening and closing strength for the movable doors 11L and 11R. Also, different opening and closing strengths may be set during normal opening and closing and other times. The opening width is typically the horizontal interval between the first movable door 11L and the second movable door 11R when the door portion 10 is fully opened. As shown in FIG. 1, if the moving distance between the fully closed position and the fully opened position of the first movable door 11L is W1, and the moving distance between the fully closed position and the fully opened position of the second movable door 11R is W2, the opening width is represented by W1 + W2. Here, the moving distances W1 and W2 can be individually set within a range that fits within the horizontal dimension of the automatic door device 100. Note that the power consumption due to the opening and closing drive of the door portion 10 during an emergency when normal power supply such as during a power outage is unavailable can be suppressed by making the opening width smaller than normal when the door portion 10 is driven by temporary power supplied from a battery.

[0038] FIG. 1 shows, as an example of the sensor 30, an activation sensor 31 as an optical sensor and a protection sensor 32. The activation sensor 31 is a photoelectric sensor provided on the surface of the blind 60 above the door portion 10. The activation sensor 31 includes a plurality of light projecting portions that project light such as infrared rays toward the floor surface, and a plurality of light receiving portions that receive the reflected light from the floor surface. When an object such as a passerby approaches the automatic door device 100 and blocks the light, the amount of light received by the light receiving portion changes, so the object can be detected. Hereinafter, when the amount of light received by the light receiving portion of the activation sensor 31 significantly changes due to the object to be detected in this way, it is said that the activation sensor 31 is in a detection state. When the detection information of the activation sensor 31 in the detection state is input to the controller 20, the door portion 10 is opened by driving the door engine 40. Note that the activation sensor 31 is provided on each of the indoor side (for example, the front side of the paper surface of FIG. 1) and the outdoor side (for example, the back side of the paper surface of FIG. 1), and can detect passersby approaching from either side.

[0039] Note that the activation sensor 31 may be configured to detect a passerby by reflection of electromagnetic waves such as microwaves or sound waves such as ultrasonic waves. Also, as shown as 31A in FIG. 1, it may be configured that a touch plate provided on at least one of the movable doors 11L and 11R is operated by a passerby to drive the door unit 10. Further, in a sightseeing facility, an amusement park, etc., in addition to or instead of detection and operation of a passerby, a mode of driving the door unit 10 by operation of a staff member of the facility is also assumed. In such a case, the staff member of the facility can remotely drive the door unit 10 with an operation panel provided at a position away from the door unit 10 or an operation terminal capable of communicating with the automatic door device 100.

[0040] The protection sensor 32 is a photoelectric sensor provided on the first fixed door 12L and the second fixed door 12R of the door unit 10. The protection sensor 32 includes a light projecting unit provided on one of the first fixed door 12L and the second fixed door 12R, and a light receiving unit provided on the other. The light projecting unit and the light receiving unit are provided at the same height from the floor surface, and light such as infrared rays projected horizontally from the light projecting unit is received by the light receiving unit. When a passerby passes through the opening and blocks the light while the door unit 10 is open, the amount of light received by the light receiving unit changes, so that the passerby can be detected. Hereinafter, when the amount of light received by the light receiving unit of the protection sensor 32 significantly changes due to a passerby or the like to be detected in this way, it is said that the protection sensor 32 is in a detection state. The main purpose of the protection sensor 32 is closing protection. When the protection sensor 32 detects a passerby during the closing operation of the movable doors 11L and 11R, the controller 20 performs inversion control to stop the closing drive and switch to the opening drive. Thereby, it is possible to prevent a passerby from being pinched by the closing movable doors 11L and 11R. Note that in such closing protection control, by using the detection information of the activation sensor 31 configured by a photoelectric sensor in the same manner as the protection sensor 32, the detection accuracy of the passerby can be improved and the safety can be further enhanced.

[0041] Note that the protection sensor 32 may be configured to detect a passerby by reflection of electromagnetic waves such as microwaves or sound waves such as ultrasonic waves. Further, the protection sensor 32 may be provided at a location different from the fixed doors 12L and 12R. For example, it may be provided at the blind area 60 like the activation sensor 31, or may be installed on the ceiling near the automatic door device 100. If a plurality of such protection sensors 32 are provided, while the cost increases, the safety is dramatically enhanced.

[0042] The door engine 40 includes a motor drive unit 41, a motor 42, and a drive pulley 43. The motor drive unit 41 is composed of an intelligent power module (IPM), and generates a voltage or current for driving the motor 42 under the control of the controller 20. The motor 42 as a power source for generating rotational power can be composed of various known motors, but in this embodiment, for example, it is composed of a brushless motor provided with an encoder using a Hall element. Information on the position of the rotor of the motor 42 detected by the encoder is input to the motor drive unit 41, and a drive voltage or drive current corresponding thereto is applied to the motor 42, thereby generating a desired rotational power. The drive pulley 43 rotationally driven by the motor 42 is connected to the rotor of the motor 42 via a gear mechanism (not shown) and rotates in conjunction.

[0043] The power transmission unit 50 transmits the power generated by the door engine 40 to the door unit 10 to drive the movable doors 11L and 11R to open and close. The power transmission unit 50 includes a power transmission belt 51, a driven pulley 52, and a connecting member 53. The power transmission belt 51 is an annular timing belt having a large number of teeth formed on its inner peripheral surface, is wound around the drive pulley 43 on the right side of FIG. 1, and is wound around the driven pulley 52 on the left side of FIG. 1. In this state, the horizontal dimension of the power transmission belt 51 is equal to the horizontal distance between the drive pulley 43 and the driven pulley 52, and is also approximately the same as the horizontal dimension of the movable range of the movable doors 11L and 11R. When the drive pulley 43 rotates by the motor 42, the driven pulley 52 rotates in conjunction via the power transmission belt 51.

[0044] The connecting member 53 connects the movable doors 11L and 11R to the power transmission belt 51 respectively and drives them to open and close. Here, one movable door is connected to the upper side of the power transmission belt 51, and the other movable door is connected to the lower side of the power transmission belt 51. In the example of Fig. 1, when the power transmission belt 51 rotates counterclockwise, the first movable door 11L moves to the left and the second movable door 11R moves to the right for the opening operation. When the power transmission belt 51 rotates clockwise, the first movable door 11L moves to the right and the second movable door 11R moves to the left for the closing operation.

[0045] In the automatic door device 100 configured as described above, when the activation sensor 31 detects a passerby, the door engine 40 generates a counterclockwise rotational power under the control of the controller 20 to drive the door unit 10 to open. Also, after the opening drive, when the state where no passerby is detected continues for a predetermined time, the door engine 40 generates a clockwise rotational power under the control of the controller 20 to drive the door unit 10 to close. In addition, when the protection sensor 32 or the activation sensor 31 detects a passerby during the closing drive, the controller 20 performs a reverse control to switch from the closing drive to the opening drive.

[0046] Fig. 2 schematically shows various component devices that can communicate with each other inside and outside the automatic door device 100. The automatic door device 100 includes a bus 2 to which each component device is connected for data communication between the component devices. The bus 2 is configured according to an arbitrary communication standard, for example, CAN (Controller Area Network). CAN is designed so that component devices can communicate with each other without going through a host computer and is widely used for transmitting control information of various systems not limited to automatic door devices. Each component device connected to the bus 2 can transmit information to other component devices via the bus 2 and can selectively receive the information necessary for itself among the information transmitted by other component devices to the bus 2.

[0047] Each functional block shown in FIG. 2 can be realized, in terms of hardware, by electronic elements such as a computer's CPU and mechanical parts, and in terms of software, by a computer program or the like. Here, however, functional blocks realized by the cooperation thereof are depicted. Therefore, it is understood by those skilled in the art that these functional blocks can be realized in various forms by combinations of hardware and software.

[0048] FIG. 2 illustrates, as constituent devices connected to bus 2, controller 20, activation sensor 31, touch plate 31A, protection sensor 32, operation panel 33, authentication device 34, electric lock controller 35, external interface 36, and display device 37, and each of these constituent devices constitutes automatic door device 100. Note that this figure is an illustrative list of constituent devices that can be connected to bus 2, and constituent devices not shown in FIG. 1 are also shown. Also, the constituent devices provided in the actual automatic door device 100 can be selected according to the purpose, and it is not necessary to provide all the constituent devices shown. For example, in an automatic door device 100 that drives door unit 10 only by detecting and operating a passerby, it is not necessary to provide operation panel 33 for an operator such as a staff member to perform an operation. Conversely, in an automatic door device 100 that drives door unit 10 only by an operation of a facility staff member in a sightseeing facility, amusement park, or the like, it is not necessary to provide activation sensor 31 and touch plate 31A for detecting and operating a passerby. However, controller 20 that controls the entire automatic door device 100 is an essential constituent device in many cases.

[0049] Among the illustrated components, the controller 20, activation sensor 31, touch plate 31A, and protection sensor 32 have been described above, so their descriptions will be omitted. The operation panel 33 is a control panel that is operated by the facility staff at tourist facilities, amusement parks, etc. to drive the door unit 10. For example, in an attraction where users move to different rooms at a predetermined timing, the staff operates the operation panel 33 in accordance with the movement timing to control the opening and closing of the door unit 10 of each room, enabling the users to move smoothly. Note that the operation panel 33 may be fixedly installed in the facility or may be portable by the staff. Also, the function of the operation panel 33 may be realized on an information communication device such as a tablet terminal or a smartphone that can communicate with the controller 20 etc. via an external interface 36 described later.

[0050] The authentication device 34 authenticates the passerby who should be permitted to pass at locations where a high level of security is required, such as the entrances of apartment buildings and offices. The authentication methods include password authentication by input on a keypad provided near the door unit 10 and biometric authentication using biometric information of the passerby such as fingerprints. When the authentication by the authentication device 34 is successful, the controller 20 drives the door unit 10 to open, and the passerby can pass through the automatic door device 100. When the authentication by the authentication device 34 fails, even if the activation sensor 31 has detected the passerby, the controller 20 does not drive the door unit 10 to open, and can prevent unauthorized passage of unauthenticated passersby.

[0051] The electric lock controller 35 controls the electric lock 35A that locks the automatic door device 100. The electric lock 35A includes, as lock driving means for driving the lock between the locked position and the unlocked position, for example, a solenoid that generates a driving force according to the energized state.

[0052] The external interface 36 inputs and outputs signals to and from various external devices 36A outside the automatic door device 100 through a wired or wireless connection. Examples of the external devices 36A include work terminals such as regulators used by workers who have come to the site for the installation, maintenance, and inspection of the automatic door device 100, and remote servers and computers connected via a public information communication network such as the Internet. Also, the functions of the image control unit of the present embodiment described later may be realized by an external device 36A outside the automatic door device 100 or may be realized within the automatic door device 100. When the functions of the image control unit are realized by the external device 36A, it is preferable to use, as the external device 36A, a server or a computer provided in a backyard for centrally managing and controlling a plurality of automatic door devices 100 within the same building. By such an input operation of the external device 36A, various settings such as control of each constituent device of the automatic door device 100 and parameter adjustment can be performed. Further, the external device 36A can read information from each constituent device of the automatic door device 100 and a memory provided therewith, and perform state diagnosis and maintenance inspection of the automatic door device 100. As described above, the bus 2 within the automatic door device 100 is configured in accordance with the CAN standard. However, when the communication between the external device 36A and the external interface 36 is performed according to a different standard, for example, Bluetooth (registered trademark) or Wi-Fi (registered trademark), the external interface 36 functions as a protocol converter that converts a signal based on one standard into a signal based on the other standard.

[0053] The display device 37 displays an image based on an image signal received from other constituent devices or the external device 36A. The display device 37 is installed on the surface of any one of the fixed doors 12L, 12R, the movable doors 11L, 11R, and the guard screen 19 described later. Details of the display device 37 will be described later.

[0054] The component devices that make up the automatic door device 100 exemplified above, namely, the controller 20, the activation sensor 31, the touch plate 31A, the protection sensor 32, the operation panel 33, the authentication device 34, the electric lock controller 35, the external interface 36, and the display device 37, can communicate with each other via a bus 2 compliant with the CAN standard. That is, each component device incorporates a CAN transceiver and a CAN controller for CAN communication. In addition to these, the external interface 36 has a protocol conversion unit that performs protocol conversion between the communication standard used by the external device 36A and the CAN standard. As a result, the external device 36A connected to the external interface 36 can communicate with the other component devices of the automatic door device 100 via the bus 2.

[0055] [First Installation Example] The outline of the automatic door device 100 has been described above with reference to FIGS. 1 and 2. Subsequently, an installation example of the display device 37 will be described. FIG. 3 is a front view of the fixed door 12 schematically showing a first installation example of the display device 37. FIG. 4 is a view showing a state in which a back cover 350 covering the back surface (the front side of the paper surface in FIG. 3) of the display device 37 is removed from the front view of FIG. 3. FIG. 5 is a cross-sectional view taken along the line A-A of FIG. 3. In this installation example and the second and third installation examples described later, the display device 37 is attached to at least one surface 15 of the fixed door 12, but the display device 37 may be attached to the surface of a guard screen described later.

[0056] As shown in FIG. 3, the surface 15 of the fixed door 12 is a rectangular area surrounded by a rectangular frame (hereinafter also referred to as a "sash") formed by a pair of vertical frames (left vertical frame 151L and right vertical frame 151R) that support the door body of the fixed door 12 from the left and right, and a pair of horizontal frames (upper horizontal frame 152U and lower horizontal frame 152D) that support the door body of the fixed door 12 from the top and bottom. A blind 60 is located above the upper horizontal frame 152U. The left vertical frame 151L is fixed to a vertical frame 16 for attaching the entire automatic door device 100 (especially the movable door 11 and the fixed door 12). Note that the sash of the fixed door 12 may not include the left vertical frame 151L, and instead, the vertical frame 16 may constitute one of the pair of vertical frames. The right vertical frame 151R is also referred to as a middle upright.

[0057] As shown in FIG. 4, the display device 37 includes a display unit 200 and a frame body 250. The frame body 250 is a rectangular four-sided frame in the front view shown in FIG. 4. The display unit 200 is disposed in a rectangular area defined by the frame body 250 in the front view shown in FIG. 4 with almost no gap, and is rectangular as a whole.

[0058] The display unit 200 in this installation example is composed of a plurality of display panels 210 connected to each other. In the example shown in FIG. 4, a total of 18 display panels 210, three in the horizontal direction and six in the vertical direction, are arranged in a grid pattern. Further, as shown in FIGS. 4 and 5, the plurality of display panels 210 are fixed to a grid-shaped reinforcing member 230 located on the back side thereof (the front side of the paper surface in FIG. 4, the right side in FIG. 5) by fixing tools 240 such as magnets, thereby being connected to each other. The display panel 210 is configured to include a display device using, for example, an LED (Light Emitting Diode) or an OLED (Organic Light-Emitting Diode).

[0059] As shown in FIG. 5, the display device 37 is installed in a direction in which the display surface 202 for displaying an image among the display units 200 faces the surface 15 of the fixed door 12. The plurality of display panels 210 constituting the display unit 200 each have a display surface and constitute one display surface 202 as a whole.

[0060] At least a portion of the surface 15 of the fixed door 12 corresponding to the display surface 202 is made of a light-transmitting material such as glass that transmits light. Thereby, a person located on the opposite side of the display device 37 (the left side in FIG. 5) through the fixed door 12 can visually recognize the image displayed by the display device 37. A portion of the surface 15 of the fixed door 12 other than the portion corresponding to the display surface 202 may be made of a light-shielding material, or a light-shielding member such as a light-shielding filter may be attached thereto. Thereby, since the light transmitted through the fixed door 12 around the display device 37 can be reduced, the intensity of the light from the display surface 202 of the display device 37 can be relatively increased, and the visibility of the display surface 202 can be enhanced.

[0061] For example, by synchronizing the images to be displayed on each display panel 210 by an image control unit (not shown) that controls the image display of the display device 37, a plurality of display panels 210 can display a single large composite image on the display surface 202. As a result, the fixed door 12 functions as if it were a single display.

[0062] The frame body 250 surrounds the entire outer periphery of the display unit 200 as viewed from a direction orthogonal to the display surface 202 (for example, the direction of the viewing point in FIG. 4). The frame body 250 directly or indirectly fixes the display unit 200 via the reinforcing member 230. The frame body 250 preferably has a certain degree of rigidity from the viewpoints of ease of handling when installing the display device 37 on the fixed door 12 and improving stability after installation.

[0063] The frame body 250 is joined to the surface 15 of the fixed door 12 via a joining member 310 which is a sealing material such as a double-sided tape. In other words, the joining member 310 joins the surface 15 of the fixed door 12 and the frame body 250. As shown in FIG. 4, the joining member 310 is arranged along the frame body 250 without gaps over the entire periphery of the display unit 200.

[0064] As shown in FIGS. 3 and 5, a back cover 350 is attached to the display device 37 so as to cover the back surface which is the surface opposite to the side where the display surface 202 of the display device 37 is located (the front side of the paper surface in FIG. 3, the right side in FIG. 5). The back cover 350 may be composed of a plurality of connected plate-like members 360. In the example shown in FIG. 3, three plate-like members 360 are connected in the vertical direction. The gaps between the three plate-like members 360 are blocked by a closing member 320 which is a sealing material such as packing. The back cover 350 may be composed of a single plate-like member. Also, the closing member 320 blocks the gap between the back cover 350 and the frame body 250 without gaps along the frame body 250.

[0065] The above-mentioned joint member 310, closing member 320, and rear cover 350 are collectively referred to as a partitioning member 300. That is, the partitioning member 300 includes the joint member 310, the closing member 320, and the rear cover 350. As described above, the surface 15 of the fixed door 12 and the frame body 250 are joined without a gap by the joint member 310. Also, the gap between the frame body 250 and the rear cover 350 and the gaps between the plurality of plate-like members 360 that constitute the rear cover 350 are blocked by the closing member 320. Therefore, the surface 15 of the fixed door 12, the rear cover 350, the frame body 250, the joint member 310, and the closing member 320 partition the internal space 380. The internal space 380 is a space isolated from the outside, including the space between the surface 15 of the fixed door 12 and the display surface 202 and the space between the back surface of the display unit 200 and the rear cover 350. In this way, since the internal space 380 including the space between the surface 15 of the fixed door 12 and the display surface 202 is isolated from the outside, by drying the internal space 380 with a drying material or the like, it is possible to suppress the occurrence of condensation in the space between the surface 15 of the fixed door 12 and the display surface 202. Also, it is possible to prevent foreign substances such as liquid (such as water) and dust from the outside from entering the space between the surface 15 of the fixed door 12 and the display surface 202 and the inside of the display device 37.

[0066] FIG. 6 is an enlarged view showing details near the lower end of the frame body 250 in the cross-sectional view taken along line A-A of FIG. 3. As shown in FIG. 6, a housing portion 260 is formed in the frame body 250. The housing portion 260 is a region within the internal space 380 partitioned by the bottom surface and the side surface, and is formed to be able to house a drying material such as silica gel. When the drying material is housed in the housing portion 260, the drying material is housed in the internal space 380. Since the drying material is housed in the internal space 380, even if the humidity of the internal space 380 increases, the drying material absorbs moisture, so the occurrence of condensation is suppressed. In the example shown in FIG. 6, the reinforcing member 230 is fixed to the frame body 250 by the fastening member 246.

[0067] For a person located on the opposite side of the display device 37 (the left side in FIG. 6) via the fixed door 12, the frame 250 may be made of an opaque material, for example, so that the drying material accommodated in the accommodating portion 260 cannot be visually recognized. At least any one of the constituent members facing the internal space 380 may be made of a highly hygroscopic material. Thereby, the moisture absorption performance in the internal space 380 is further improved, and the occurrence of condensation is more suppressed. Further, the back cover 350 may be configured to be detachable from the frame 250. Thereby, it becomes possible to access the accommodating portion 260 from the back side of the display device 37 while the display device 37 is installed on the surface 15, and the drying material can be easily replaced.

[0068] As shown in FIG. 6, the frame 250 may be partitioned with a hole portion 262 that guides water droplets from the surface 15 of the fixed door 12 to the accommodating portion 260. Thereby, even if condensation occurs on the surface 15 and water droplets are generated, the water droplets can be guided to the accommodating portion 260 and absorbed by the drying material. Further, the frame 250 may be provided with a hole portion that discharges water droplets from the surface 15 of the fixed door 12 to the outside of the internal space 380. Thereby, even if condensation occurs on the surface 15 and water droplets are generated, the water droplets can be discharged to the outside of the internal space 380 to eliminate the condensation. Note that the water droplets induced and absorbed by the accommodating portion 260 by the above-described hole portion 262 can also be said to be discharged to the outside of the internal space 380. That is, the hole portion for discharging the water droplets to the outside of the internal space 380 includes the hole portion 262 for guiding the water droplets to the accommodating portion 260.

[0069] As described above, the accommodating portion 260 for accommodating the drying material has been described, but the frame 250 does not necessarily have to be provided with the accommodating portion 260. It is sufficient that at least any one of the surface 15 of the fixed door 12, the display device 37, and the partitioning member 300 can dispose the drying material in the internal space 380. For example, the drying material may be disposed on at least one of the joining member 310 and the closing member 320 located below as shown in FIG. 5. For example, the drying material may be attachable to at least a part of the surface 15 of the fixed door 12 by adhesion or the like. Alternatively, the drying material may be disposed in the internal space 380 by any other arbitrary method.

[0070] FIG. 7 is an enlarged view showing details near the upper end of the frame body 250 among the cross-sectional views taken along the line A-A of FIG. 3. As shown in FIG. 7, a communication hole 254 that communicates the space on the display surface 202 side and the space on the back side of the display device 37 is defined at the boundary between the display panel 210 and the frame body 250. The communication hole 254 may be defined at the boundary between a plurality of display panels 210. Also, similar to FIG. 6, the reinforcing member 230 is fixed to the frame body 250 by the fastening member 246. Such a communication hole 254 improves the air circulation between the space between the surface 15 of the fixed door 12 and the display surface 202 of the display device 37 and the space on the back side of the display device 37 in the internal space 380, and easily suppresses the rise in humidity.

[0071] Hereinafter, with reference to FIGS. 3 to 5 again, the attachment position of the display device 37 on the surface 15 of the fixed door 12 will be described. The frame body 250 of the display device 37 is arranged along the vertical frame of the sash that is located at the end in the width direction (horizontal direction) of the fixed door 12 and extends in the vertical direction (vertical direction). In the example shown in FIG. 4, the frame body 250 is arranged along the right vertical frame 151R that is located at the right end in the horizontal direction of the fixed door 12 and extends in the vertical direction. A base member 400 that supports the frame body 250 from below is attached to the frame body 250. A support member 450 that supports the frame body 250 from the side opposite to the side where the horizontal right vertical frame 151R is located (the left side in FIG. 4) is attached to the frame body 250.

[0072] The base member 400 is arranged along the right vertical frame 151R in the same manner as the frame body 250. In the lower region of the surface 15 of the fixed door 12, it is preferable that the display device 37 is not arranged from the viewpoints of ensuring safety by ensuring visibility at the feet and aesthetics. By the base member 400 supporting the display device 37 from below, the display device 37 can be held so as not to be arranged in a certain region at the lower part of the surface 15. Also, from the same viewpoints as above, in the horizontal direction, it is preferable that the width of the base member 400 is smaller than the width of the display device 37. In the example shown in FIG. 4, in the horizontal direction, the width of the base member 400 is approximately the same as the width of the vertical frame portion of the frame body 250 that extends in the vertical direction.

[0073] In order to prevent the display device 37 from being disposed in the lower region of the surface 15 of the fixed door 12, instead of supporting the display device 37 from below by the base member 400, for example, it may be supported from above the display device 37. However, when the display device 37 is a heavy object such as about 30 kg, it is preferable to support it by the base member 400 from the viewpoint of safety. In addition to the support by the base member 400, the display device 37 may be supported from above, for example, from the upper horizontal frame 152U or the blind 60.

[0074] In the example shown in FIG. 4, the support member 450 is disposed near the center of the display device 37 in the vertical direction. In the vertical direction, the width of the support member 450 may be smaller than the width of the display device 37. In the example shown in FIG. 4, in the vertical direction, the width of the support member 450 is approximately the same as the width of the horizontal frame portion of the frame body 250 extending in the horizontal direction. The support member 450 may accommodate wiring from the display device 37 and guide it to the power supply box 490 attached to the left vertical frame 151L. Power is supplied to the display device 37 through the wiring from the power supply box 490. Also, an image signal may be input to the display device 37 through the wiring from the power supply box 490. The display device 37 may receive the image signal by wireless communication.

[0075] FIG. 8 is a plan view showing the positional relationship between the fixed door 12 on which the display device 37 is installed and the movable door 11. As shown in FIG. 8, the movable door 11 moves along the horizontal direction on the side of the fixed door 12 where the display device 37 is installed. The frame body 250 of the display device 37 is in contact with the right vertical frame 151R without a gap. If there is a gap between the display device 37 and the right vertical frame 151R, and a foreign object such as a finger is inserted into this gap, when the movable door 11 moves from the closed state on the right side of FIG. 8 to the open state by moving to the left side, there is a risk that the foreign object will be pinched. Since there is no such gap in this installation example, it is possible to prevent a foreign object from being pinched.

[0076] As shown in FIG. 4, the base member 400 is arranged along the right vertical frame 151R, similarly to the frame body 250. Therefore, similarly to the above, it is possible to prevent foreign matter from being pinched between the base member 400 and the right vertical frame 151R.

[0077] In the vertical direction of FIG. 8 (the depth direction of the paper surface of FIG. 3), the gap between the back surface of the back cover 350 and the movable door 11 is preferably a gap small enough that a finger cannot be drawn in. In this installation example, for example, the gap can be easily adjusted by adjusting the dimensions of the joining member 310 that joins the surface 15 of the fixed door 12 and the frame body 250, and / or the closing member 320 that closes the gap between the back cover 350 and the frame body 250.

[0078] FIG. 9 is a front view showing an enlarged view of the periphery of the support member 450. As shown in FIG. 9, the support member 450 is composed of, for example, a metal frame 460 and a reinforcing metal fitting 470. The metal frame 460 is a U-shaped or C-shaped member that covers at least the upper and lower sides in the vertical direction and the front side in the front-rear direction (the depth direction of the paper surface of FIG. 9). The metal frame 460 functions as a wiring accommodating portion capable of accommodating the wiring 270 from the display device 37. Thereby, it is possible to prevent the wiring 270 from being exposed to the outside. The reinforcing metal fitting 470 is an L-shaped metal fitting having a surface corresponding to the metal frame 460 in the horizontal direction and a surface corresponding to the frame body 250 or the power supply box 490 in the vertical direction. The reinforcing metal fitting 470 is fastened to the metal frame 460 and the frame body 250 or the power supply box 490 to fix the metal frame 460 to the fixed door 12.

[0079] FIG. 10 is a front view showing an enlarged view of the periphery of the base member 400. As shown in FIG. 10, the base member 400 is composed of, for example, a metal frame 410 and a reinforcing fitting 420. The metal frame 410 is at least a U-shaped or C-shaped member that covers the left and right sides in the horizontal direction and the front side in the front-rear direction (the depth direction of the paper surface of FIG. 10). The reinforcing fitting 420 is an L-shaped fitting having a surface corresponding to the metal frame 410 or the right vertical frame 151R in the vertical direction and a surface corresponding to the frame body 250 in the horizontal direction. The reinforcing fitting 420 is fastened to the metal frame 410 and the frame body 250 or the right vertical frame 151R to fix the metal frame 410 to the fixed door 12.

[0080] Here, a construction method of the automatic door device 100 will be described. The construction method of the automatic door device 100 is executed, for example, according to the following procedure. (Step 1) Determine the position on the surface 15 of the fixed door 12 where the display device 37 is to be installed. (Step 2) Adjust and process the dimensions of the base member 400 and the support member 450 according to the position where the display device 37 is to be installed. (Step 3) Attach the base member 400 to the frame body 250. (Step 4) Place the display device 37 at the position determined in Step 1. That is, the frame body 250 is arranged along the right vertical frame 151R that extends vertically at the horizontal end of the fixed door 12. At this time, the display device 37 is installed on the surface 15 of the fixed door 12 with the display surface 202 facing. (Step 5) Arrange the joint member 310 such as a double-sided tape along the frame body 250 without gaps over the entire periphery of the display unit 200 and join it to the surface 15 of the fixed door 12. (Step 6) Store a drying material in the storage unit 260. (Step 7) Arrange the partitioning member 300 so as to partition an internal space 380 isolated from the outside including at least the space between the surface 15 of the fixed door 12 and the display surface 202 of the display device 37. This step and Step 6 may be performed in advance except for the operation of Step 5. (Step 8) Attach the support member 450 that indicates from the side opposite to the side where the right vertical frame 151R in the horizontal direction is located to the frame body 250.

[0081] [Second Installation Example] Next, a second installation example of the display device 37 will be described. FIG. 11 is a cross-sectional view similar to the cross-sectional view taken along line A-A of FIG. 3, schematically showing the second installation example of the display device 37. In the drawings and descriptions of the second installation example, the same or equivalent components and members as those in the first installation example are denoted by the same reference numerals. Descriptions overlapping with those of the first installation example will be omitted as appropriate, and the configurations different from those of the first installation example will be described with emphasis.

[0082] In this installation example, the closing member 320 is provided so as to further close the gap between the display unit 200 and the frame body 250. Also, the display unit 200 of this installation example is composed of one display panel 210A. As a result, the internal space 380 is partitioned by the surface 15, the display surface 202, the joining member 310, and the closing member 320. That is, the internal space 380 of this installation example is the space between the surface 15 and the display surface 202 and does not include the space on the back side of the display device 37. Note that the display unit 200 of this installation example may be composed of a plurality of display panels 210 as in the first installation example. In that case, the gaps between the plurality of display panels 210 are closed by the closing member 320.

[0083] [Third Installation Example] FIG. 12 is a front view of the fixed door 12, schematically showing the third installation example of the display device 37. In the drawings and descriptions of the third installation example, the same or equivalent components and members as those in the second installation example are denoted by the same reference numerals. Descriptions overlapping with those of the second installation example will be omitted as appropriate, and the configurations different from those of the second installation example will be described with emphasis.

[0084] In this installation example, the back cover 350A is composed of one plate-like member. Also, on the back cover 350A, for example, one or a plurality of latching portions 370 penetrating in the front-rear direction are defined. The display device 37 has, for example, a protruding portion protruding toward the front side of the paper surface in FIG. 12, and may be fixed to the back cover 350A by hanging this protruding portion on the latching portion 370.

[0085] FIG. 13 is a plan view of the fixed door 12 schematically showing a third installation example of the display device 37. The rear cover 350A is supported rotatably with respect to the front surface 15 in a horizontal plane (in the plane along the paper surface of FIG. 13) via one or a plurality of rotation support portions 372 fixed to the front surface 15. The rotation support portion 372 is, for example, a hinge. Thus, since the rear cover 350A is supported rotatably with respect to the front surface 15, construction and maintenance inspection of the display device 37 fixed to the rear cover 350A can be facilitated.

[0086] [Fourth Installation Example] FIG. 14 is a front view of the fixed door 12 schematically showing a fourth installation example of the display device 37. In the drawings and description of the fourth installation example, the same or equivalent components and members as those in the first installation example are given the same reference numerals. Descriptions overlapping with those of the first installation example are omitted as appropriate, and configurations different from those of the first installation example are described with emphasis.

[0087] This installation example is different from the first installation example in that the display device 37 is not supported by the base member 400 and the support member 450. However, the position where the display device 37 is installed on the front surface 15 of the fixed door 12 is preferably the same as that in the first installation example for the same reasons as above. In this installation example, although not shown, the power box may be incorporated in the display device 37 or may be installed at any other location. Also, in this installation example, the display device 37 is attached to at least one of the front surfaces 15 of the fixed door 12, but the display device 37 may be attached to the front surface of the movable door 11 or may be attached to the front surface of a guard screen described later.

[0088] [Fifth Installation Example] FIG. 15 is a schematic plan view of an automatic door device 100 provided with a guard screen 19 in addition to a movable door 11 and a fixed door 12. In the example of FIG. 15, the movable door 11 is positioned between the open state and the closed state. The guard screen 19 is provided to face the fixed door 12 with the movable door 11 in the open state interposed therebetween. By attaching a light-shielding film to the surface of the guard screen 19 facing the display device 37, light can be prevented from leaking from the gap of the display device 37 provided on the fixed door 12.

[0089] The guard screen 19 prevents a person or an object from contacting the fixed door 12 or the movable door 11 that moves when the movable door 11 is in the closed state or when it transitions from the closed state to the open state. In the illustrated example, since the display device 37 is provided on the fixed door 12, the guard screen 19 can also prevent a person or an object from contacting the display device 37.
