[Automatic opening and closing door 1]
First, an automatic door 1 according to a first embodiment of the present invention will be described with reference to Figures 1 to 5. The automatic door 1 according to this embodiment is configured so that it can be opened as a swing door by rotating the door body 2 towards the back of the page in Figure 1. In this specification, the side to which the door body 2 is rotated when opening the automatic door 1 will be described as the rear of the automatic door 1.

As shown in Figures 1 to 3, an automatic opening and closing door 1 equipped with a door body 2 is installed between a floor F and a ceiling C. In addition to the door body 2, the automatic opening and closing door 1 also includes a top rail 3, a door edge frame 4, a door front frame 5, an upper frame 6, an upper hinge 7, a lower hinge 8, an automatic opening and closing device 9, a non-contact switch 31, and wiring C1 to C3 connecting each part. Each element that makes up the automatic opening and closing door 1 is primarily made of a steel alloy or an aluminum alloy.

The trailing edge frame 4, leading edge frame 5, and upper frame 6 are arranged around the trailing edge, leading edge, and upper edge of the door body 2, respectively. The trailing edge frame 4, leading edge frame 5, and upper frame 6 constitute a door frame that rotatably supports the door body 2 via upper hinges 7 and lower hinges 8. In other words, the door body 2 is rotatably attached to the door frame made up of the trailing edge frame 4, leading edge frame 5, and upper frame 6 via the upper hinges 7 and lower hinges 8. Specifically, as shown in Figure 2, the upper end of the trailing edge side of the door body 2 is connected to the upper frame 6 by the upper hinge 7. Furthermore, the lower end of the trailing edge side of the door body 2 is connected to the lower end of the trailing edge frame 4 by the lower hinge 8.

As shown in Figure 2, the top frame 6 is fixed to the top rail 3 which is fixed to the ceiling C. As shown in Figure 3, the tail frame 4 and front frame 5 are each vertical frames fixed to support posts S, S which are erected at a distance between the floor F and the ceiling C. On the support post S on the side of the front frame 5 (right side in Figure 1), front-end panels 21, 21 are provided on both the front and back sides opposite the tail frame 5. Similarly, on the support post S on the side of the tail frame 4 (left side in Figure 1), rear-end panels 22, 22 are provided on both the front and back sides opposite the tail frame 4.

The automatic door 1 is equipped with an automatic opening/closing device 9 that electrically rotates the door body 2 in accordance with a signal from a non-contact switch 31. The non-contact switch 31 is equipped with a detection unit 32, which serves as an indicator in this embodiment.

The automatic door opening/closing device 9 is a commercially available electric door opening/closing device that includes an operating unit 91, a power supply unit 92 equipped with an adapter and connector, a plug 93, and a cord 94 that electrically connects these. The operating unit 91 is fixed to the door body 2 and is rotatably connected to the upper frame 6 via an arm 91a and a link 91b.

The operating unit 91 houses a drive shaft that rotates around a vertical axis and a motor that rotates the drive shaft. The base end of an arm 91a is connected to the upper end of this drive shaft. The arm 91a rotates integrally with the drive shaft around the drive shaft. The base end of a link 91b is fixed to the upper frame 6, and the tip of the link 91b is rotatably connected to the tip of the arm 91a. The operating unit 91 houses a control unit that controls the operation of the automatic opening and closing device 9.

The control unit of the automatic opening/closing device 9 controls the motor that rotates the drive shaft in accordance with a signal from the detection unit 32, which is the instruction unit in this embodiment. When the motor in the operation unit 91 receives a signal from the detection unit 32, it rotates the drive shaft, causing the arm 91a to rotate relative to the link 91b, and the door body 2 to open or close relative to the door frame.

As shown in FIG. 1, the automatic opening and closing device 9 is electrically connected to the non-contact switch 31 via metal wiring C2, conductive metal fitting 10, and switch wiring C3. Power is supplied to the non-contact switch 31 through these metal wiring C2, conductive metal fitting 10, and switch wiring C3, and a signal from the non-contact switch 31 is sent to the automatic opening and closing device 9.

The metal wiring C2 extends from the operating section 91 and is inserted into the interior of the door body 2, where it is connected to the conductive metal fitting 10 through the interior space of the door body 2. The conductive metal fitting 10 is a commercially available component used to run wires between the door body 2 and the tail frame 4. The switch wiring C3 passes from the conductive metal fitting 10 through the tail frame 4, top frame 6, and top rail 3, and is inserted into the leading edge panel 21, where it is connected to a non-contact switch 31 provided on the surface of each of the front and rear leading edge panels 21.

As shown in FIG. 1, the automatic opening and closing device 9 is connected to a 100V external power supply via a power supply unit 92 and a plug 93. Specifically, the automatic opening and closing device 9 is connected to the external power supply by connecting the external plug P, which is provided at the end of the external wiring C1 connected to the external power supply, to the plug 93. In other words, the automatic opening and closing device 9 is supplied with power from the external power supply via the power supply unit 92 and the plug 93.

As shown in Figures 1 and 3, a pull tab 11 is provided at the vertical midpoint of the trailing edge of the door body 2. The user can manually open and close the door body 2 by grasping and operating the pull tab portion 11a formed on the pull tab 11. It is also possible for the user to open the door body 2 from the front by pushing the door body 2. This manual method of opening and closing the door body 2 can also be used when the power supply to the automatic opening and closing device 9 is cut off, such as during a power outage. The door body 2 can also be configured to be lockable by providing a lock.

As shown in Figures 1 and 2, in the automatic opening and closing door 1 according to this embodiment, a power supply unit 92, such as an adapter or connector, is housed in the internal space 6s of the upper frame 6 that constitutes the door frame. Furthermore, a plug 93 and an external plug P are connected in the internal space 6s of the upper frame 6. A cord 94 connecting the power supply unit 92 and the operating unit 91 is inserted into an insertion hole that opens on the front surface of the upper frame 6. As described above, in this embodiment, the power supply unit 92 is housed in the internal space 6s of the upper frame 6, which is the door frame, in a location that is not visible from the outside. This makes it possible to easily position the power supply unit 92 near the operating unit 91.

For example, if the power supply unit 92 is to be placed above the ceiling C, it is necessary to form an opening that penetrates the ceiling C and insert the power supply unit 92 or thread the cord 94 through that opening. In this embodiment, the power supply unit 92 is housed in the door frame, so only the external wiring C1 passes through the ceiling C. In other words, by housing the power supply unit 92 in the door frame as in this embodiment, the automatic opening and closing door 1 can be installed with a simple configuration. Furthermore, the power supply unit 92 can be removed by removing the upper frame 6, which is the door frame, from the top rail 3, so the automatic opening and closing door 1 can be easily relocated.

In the automatic opening and closing door 1 according to this embodiment, the power supply unit 92 is housed in the top frame 6, but the power supply unit 92 may be housed anywhere inside the door frame. In other words, it is also possible to house all or part of the power supply unit 92 inside the tail frame 4 or the leading frame 5. In this case, it is also possible to house the power supply unit 92 separately in each of the tail frame 4, leading frame 5, and top frame 6.

However, if part or all of the power supply unit 92 is housed in the tail frame 4 or front frame 5, a support member such as a bracket to support the power supply unit 92 is required. For this reason, as in this embodiment, it is preferable to have the top frame 6 house the entire power supply unit 92, thereby eliminating the need for a separate support member.

As shown in Figures 2, 4, and 5, in the automatic opening and closing door 1 according to this embodiment, a communication hole 61 is formed in the underside of the upper frame 6, connecting the inside and outside of the upper frame 6. Specifically, the communication hole 61 is a generally rectangular opening in the underside of the upper frame 6, with an engaging portion 61a formed around its periphery. As shown in Figures 4 and 5, the communication hole 61 can be closed with a closing plate 62.

The closure plate 62 is formed with a claw portion 62a, which is engaged with the engaged portion 61a, thereby blocking the communication hole 61 with the closure plate 62. As shown in Figure 4, by screwing the restricting screw 63 into the upper frame 6 while the communication hole 61 is blocked by the closure plate 62, the displacement of the closure plate 62 is restricted and the closure plate 62 cannot be removed from the upper frame 6.

The automatic opening and closing door 1 according to this embodiment, configured as described above, allows the power supply unit 92 to be connected to an external power source through the communication hole 61. Specifically, before the upper frame 6 is assembled to the top rail 3, the power supply unit 92 is pre-stored in the internal space 6s of the upper frame 6. As shown in Figures 2, 4, and 5, an opening 6a is formed in the top surface of the upper frame 6, so the power supply unit 92 can be easily stored in the upper frame 6 through the opening 6a.

When the power supply unit 92 is housed in the internal space 6s of the upper frame 6, the plug 93 is left extending from the communication hole 61. Then, with the upper frame 6 attached to the top rail 3, the external plug P connected to the external power supply is extended from the communication hole 61 and connected to the plug 93. The plug 93 and external plug P are then inserted into the internal space 6s of the upper frame 6 through the communication hole 61, and the communication hole 61 is closed with the closing plate 62.

In the automatic opening and closing door 1 according to this embodiment, the non-contact switch 31 equipped with the detection unit 32 is provided on the door-end panel 21, which is the wall surface adjacent to the door end frame 5. The detection unit 32 serves as an instruction unit in this embodiment, transmitting a signal to the automatic opening and closing device 9 to rotate the door main body 2.

In this embodiment, the configuration described above allows the user of the automatic opening and closing door 1 to open or close the door body 2 by sending a signal from the detection unit 32. Specifically, the detection unit 32 is configured as a non-contact sensor, and the user can open or close the door body 2 by holding their hand or an object over the detection unit 32.

In the automatic door 1 according to this embodiment, a non-contact sensor is used for the detection unit 32 so that a signal can be transmitted without the user having to touch the detection unit 32. This improves the convenience and cleanliness of the automatic door 1 when in use. Specifically, it prevents the transmission of germs and viruses via the detection unit 32. Furthermore, even if the user has both hands full, the automatic door 1 can be opened and closed simply by bringing an item or part of the body close to the detection unit 32, improving the convenience of the automatic door 1.

As shown in FIG. 1, in the automatic opening and closing door 1 according to this embodiment, the automatic opening and closing device 9 and the detection unit 32 are electrically connected via metal wiring C2 and switch wiring C3. Furthermore, metal wiring C2, which is part of the wiring, is inserted inside the door main body 2. In this way, in the automatic opening and closing door 1 according to this embodiment, by accommodating the metal wiring C2 inside the door main body 2, exposure of the wiring is suppressed, improving the aesthetic appeal of the automatic opening and closing door 1.

[Automatic opening and closing door 1A]
Next, an automatic opening and closing door 1A according to a second embodiment of the present invention will be described with reference to Figures 6 and 7. The automatic opening and closing door 1A according to this embodiment differs from the automatic opening and closing door 1 according to the first embodiment in the shapes and arrangement of the door body 2, end frame 4, front frame 5, and top frame 6. The following description of this embodiment will focus on the parts that differ from the first embodiment, and detailed description of parts that are common to both embodiments will be omitted.

As shown in Figure 6, the automatic opening and closing door 1A according to this embodiment includes a door body 2, a top rail 3, a tail frame 4, a front frame 5, an upper frame 6, an upper hinge 7, a lower hinge 8, an automatic opening and closing device 9, an upper vertical frame 12, an upper upper frame 13, a non-contact switch 31, and wiring C1 to C3 connecting each part.

As shown in Figure 6, in the automatic opening and closing door 1A according to this embodiment, a gap is formed between the upper frame 6 and the ceiling C. Specifically, as shown in Figure 7, an upper upper frame 13 is fixed to the top rail 3, and upper vertical frames 12, 12 are fixed to the support posts S (see Figure 3) above the end frame 4 and front frame 5. In other words, an open area surrounded by the upper frame 6, upper vertical frames 12, 12, and upper upper frame 13 is formed above the door body 2.

In this embodiment, an open area is formed above the upper frame 6, and as shown in Figure 7, the opening 6a formed on the upper surface of the upper frame 6 is closed by a closing member 64. In addition, in this embodiment, an open area is also formed above the leading panel 21 and trailing panel 22, surrounded by the upper frame 6, upper vertical frames 12, and upper upper frame 13.

As shown in Figure 6, the automatic opening and closing device 9 in this embodiment is electrically connected to the non-contact switch 31 via the metal wiring C2, the conductive metal fitting 10, and the switch wiring C3. The switch wiring C3 passes from the conductive metal fitting 10 through the tail frame 4, the top frame 6, the upper vertical frame 12 above the front frame 5, the top rail 3, and the inside of the upper vertical frame 12 above the front panel 21, and is inserted into the front panel 21, where it is connected to the non-contact switches 31 provided on the surface of each of the front and rear front panel 21.

As shown in FIG. 6, the automatic opening and closing device 9 is connected to a 100V external power source via a power supply unit 92 and a plug 93. Specifically, the automatic opening and closing device 9 is connected to the external power source by connecting the plug 93 to an external plug P provided at the tip of an external wiring C1 that is inserted inside the upper vertical frame 12 and connected to the external power source. In other words, the automatic opening and closing device 9 is supplied with power from the external power source via the power supply unit 92 and the plug 93.

As shown in Figures 6 and 7, in the automatic opening and closing door 1A according to this embodiment, a power supply unit 92 such as an adapter or connector is housed in the internal space 6s of the upper frame 6 that constitutes the door frame. Furthermore, the plug 93 and the external plug P are connected in the internal space 6s of the upper frame 6. As described above, in this embodiment, the power supply unit 92 is housed in the internal space 6s of the upper frame 6, which is the door frame, in a location that is not visible from the outside. This makes it possible to easily position the power supply unit 92 near the operating unit 91.

In this embodiment, an open gap is formed above the upper frame 6. After the upper frame 6 is installed, the power supply unit 92 can be accommodated in the internal space 6s of the upper frame 6 through the opening 6a, and the opening 6a can then be closed with the closing member 64. In this way, in this embodiment, by accommodating the power supply unit 92 in the upper frame 6 with a gap formed above, the automatic opening-closing door 1A can be installed with a simpler configuration. When this configuration is adopted, it is also possible to configure the upper frame 6 without forming the communication hole 61. Note that the automatic opening-closing door 1A according to this embodiment can also be configured so that the power supply unit 92 is connected to an external power source via the communication hole 61, just like the automatic opening-closing door 1 according to the previous embodiment.

[Other Modifications]
The above embodiment can be modified as appropriate as shown in the other modifications below. Note that each modification described in this specification may be applied in combination with other modifications to the extent that no contradiction occurs.

In the automatic door according to the present invention, the door frame that houses the power supply unit can be a vertical frame (end frame or front frame) located to the side of the door body, or an upper frame located above the door body. It is also possible to configure the power supply unit to be split and housed in both the vertical frame and the upper frame.

Furthermore, in the automatic opening and closing door according to the present invention, the plug connected to the power supply unit via a cord and the external plug may be connected in a location other than the interior space of the door frame (for example, above the ceiling).

Furthermore, with an automatic door that opens and closes, it is possible to provide a gap between the ceiling and the upper frame that houses the power supply unit, as in the second embodiment above. It is also possible to provide a panel member (a so-called transom panel) such as a steel panel or glass panel in the gap between the door frame and the ceiling.

As described above, if a steel panel is installed as a transom panel in the gap between the door frame and the ceiling, it is also possible to configure the external wiring C1 and switch wiring C3 to be inserted between the steel panels. However, if a glass panel is installed as the transom panel, it is preferable to insert the external wiring C1 and switch wiring C3 inside the upper vertical frame 12, as in the second embodiment above, to prevent the wiring from being exposed.

In the automatic opening and closing door according to the present invention, the detection unit may be located in a different location from that in the above embodiment, as long as it is on a wall surface adjacent to the door frame. For example, the detection unit may be located on the wall surface on the door trailing edge (the door trailing edge panel 22 in the above embodiment). If a non-contact sensor is used for the detection unit, it is necessary to ensure a certain distance between the non-contact sensor and the rotation trajectory of the door body so that it does not detect the opening and closing operation of the door body and send instructions to the automatic opening and closing device.

In the automatic opening and closing door of the present invention, the detection unit can also be installed on the door body. In this case, the conductive metal fittings 10 and metal wiring C2 described in the above embodiment are unnecessary, and the operating unit 91 of the automatic opening and closing device 9 can be directly connected to the detection unit via the switch wiring C3. In this case, the entire switch wiring C3 can be housed inside the door body. Furthermore, if a non-contact sensor is installed on the door body, it is preferable to position the non-contact sensor at least 100 mm toward the end of the door to prevent it from detecting the door frame or the like during the door closing operation and causing a malfunction.

In the automatic door according to the present invention, it is also possible to use a configuration other than a non-contact sensor as the command unit. For example, it is possible to configure the command unit to command the operation of the automatic door-opening device 9 by inputting a PIN number. It is also possible to configure the command unit to command the operation of the automatic door-opening device 9 by remote command from a location distant from the automatic door (such as a security room). It is also possible to use an authentication system using a personal authentication card or a biometric authentication system such as face authentication, fingerprint authentication, iris authentication, vein authentication, or voiceprint authentication as the detection unit.
