In the following description, the same reference numerals in different figures denote portions having the same function, and duplication of description in each figure will be omitted as appropriate.

(First embodiment)
A first embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a right side view showing a case where a person exists outside the automatic opening/closing door according to the first embodiment, and FIG. 2 shows a case where a person exists inside the automatic opening/closing door according to the first embodiment. is a right side view shown. 3 is a front view of the automatic opening/closing door of the first embodiment as seen from the outside, and FIG. 4 is a rear view of the automatic opening/closing door of the first embodiment as seen from the inside. Moreover, FIG. 5 is a perspective view of an inner human sensor.

As understood from FIGS. 1 to 4, the automatic opening/closing door 1 of the first embodiment is in the form of a sliding door 10. As shown in FIG. The automatic opening/closing door 1 includes a door frame 15 , a sliding door 10 having an outer door surface 11 and an inner door surface 12 indoors and outdoors, and an opening/closing mechanism (not shown) for electrically opening/closing the sliding door 10 .

The indoor and outdoor doors are provided with a large lever type outer opening/closing operation part 13 and an inner opening/closing operation part 14 that are operated by a person to open/close the sliding door 10, as is the case with the normal specification sliding door. In addition to this, in the first embodiment, when the upper electric lock 21 and the lower electric lock 24 are unlocked, and the outer human sensor 31 or the inner human sensor 32 detects a body intrusion within a predetermined range. The sliding door 10 is configured to be automatically opened when it is detected that it has been opened. However, when the upper electric lock 21 and the lower electric lock 24 are locked, they are not opened even if the outside human sensor 31 or the like detects a person.

The opening/closing mechanism is electrically driven, and is composed of a driver section that combines an actuator such as a motor with gears or racks and drives the motor or the like. However, other than this, any driving mechanism such as using a pulley and a belt can be used. In the first embodiment, it is configured to be electrically driven both when opening and closing, but when it is opened, it is electrically driven, and when it is closed, it is electrically driven by a general door closer having biasing means. Alternatively, the sliding door 10 may be closed.

The upper electric lock 21 and the lower electric lock 24 unlock and lock the sliding door 10 . The upper electric lock 21 and the lower electric lock 24 each have a deadbolt, a drive section, and a drive circuit (all not shown). The drive unit includes an electric motor and a transmission mechanism that transmits the driving force of the electric motor to the deadbolt, and drives the electric motor according to a drive signal input from the drive circuit. The deadbolt moves to the locked position or the unlocked position by transmitting the driving force of the electric motor to the deadbolt via the transmission mechanism. Here, when the deadbolt is moved to the locking position, at least part of the deadbolt is inserted into the bolt hole provided in the door frame, and in this state, the sliding door 10 is held closed. That is, the sliding door 10 is locked. When the deadbolt is moved to the unlocked position, the deadbolt is entirely out of the bolt hole and is automatically opened and closed by electric drive. Even when the opening/closing mechanism is turned off due to a power failure or the like, the sliding door 10 can be opened/closed by operating the outer opening/closing operation portion 13 . As shown in FIG. 3, since the upper electric lock 21 and the lower electric lock 24 have keyholes, they can be unlocked by inserting a key in the event of a power failure, etc., and a one-door two-lock for crime prevention. It is considered a method. From the inside, it can also be unlocked manually by the upper and lower thumb-turns.

The drive circuits of the upper electric lock 21 and the lower electric lock 24 have a determination section, and the determination section determines whether or not the electronic key 23 held by a person exists within a set distance 22 of the electric lock. The electronic key 23 is composed of an electronic component such as an IC chip having a storage area for storing various information in a readable and writable manner, and stores ID information necessary for authentication of permission to unlock the sliding door 10 in the storage area. The electronic key 23 is capable of non-contact communication (short-range wireless communication) with a reader (not shown) installed indoors or outdoors by electromagnetic waves, radio waves, magnetic field coupling, or electric field coupling, and communicates within the set distance 22 of the electric lock. It can send and receive signals.

The detection range of the electronic key 23 is set to about 2 m from the door in the first embodiment. As indicated by the dotted circles in FIGS. 1 and 2, the detection range of the electronic key 23 is approximately the same for both indoor and outdoor readers, but it may be set so that the detection range is different indoors and outdoors. . In the first embodiment, the processing executed after the reader receives the ID information is processing in which the outer human sensor 31 or the inner human sensor 32 detects the body and performs automatic opening/closing processing. The process is the same inside and outside. For example, even if the body is detected outdoors after the electronic key 23 is detected indoors, the process may be different indoors and outdoors, such as not to automatically open and close. As a result, it is possible to prevent the sliding door 10 from being carelessly opened when a suspicious person is present outdoors.

The electronic key 23 may be a passive type (so-called secondary radar or RFID tag) card-shaped storage medium that generates power in response to electromagnetic waves, radio waves, magnetic field coupling, or electrolytic coupling from an indoor or outdoor reader. Alternatively, it may be an active remote control key powered by a built-in battery. However, a passive type is preferable in order to set the detection range of the electronic key 23 to an appropriate value such as 2 m. This is because the detection range tends to be large in the active type, but it goes without saying that the active type may be adopted as long as the detection range can be suppressed within an appropriate range by an appropriate method. Alternatively, a non-contact communication function provided in a smartphone or tablet may be used to communicate ID information required for authentication with a reader provided indoors or outdoors.

After the upper electric lock 21 and the lower electric lock 24 are unlocked, it is the motion sensor 3 provided indoors and outdoors that gives the opportunity to operate the opening and closing mechanism. are different. As shown in FIGS. 1 and 3, the outside motion sensor 31 is provided near the top of the door when the sliding door 10 of the upper frame is closed. On the other hand, the inside motion sensor 32 is provided inside the door frame 15 at a height slightly above the inside opening/closing operation portion 14, as shown in FIGS. As shown in FIG. 5, the housing of the inner human sensor 32 has left and right side walls so that the left and right detection ranges when facing the inner sensor 32 are narrowed down. Specifically, in the first embodiment, as shown in FIG. 7, the left and right detection ranges are set to approximately the expected width P of the door frame 15 .

(Detection range of the human sensor of the first embodiment)
A detection range of the human sensor 3 of the first embodiment will be described. FIG. 6 is an explanatory diagram showing the detection range of the human sensor 3 when a person is outside the automatic door. A two-dot chain line indicates the detection range. In FIG. 6 , the outer human sensor 31 detects that a person is within reach of the outer opening/closing operation portion 13 . In the drawing, the hand is stretched out and the upper arm is also detected. It is determined by detecting whether or not a person exists within a range where the outer opening/closing operation portion 13 can be reached by stretching out a hand.

FIG. 7 is an explanatory diagram showing the detection range of the human sensor 3 when a person is inside the automatic opening/closing door. A two-dot chain line indicates the detection range. In FIG. 7, the inside human sensor 32 detects that the body is intruding within the range of the door frame 15 .

As described above, the detection range of the electronic key 23 is set to about 2 m from the door, which is larger than the detection range of the indoor/outdoor motion sensor 3 . A method of automatically opening the door when the electronic key 23 is detected is also conceivable, but this is not preferable from the viewpoint of security. The concept of the automatic door of the present invention is fundamentally different from that of automatic doors installed in office buildings through which an unspecified number of people frequently pass. It is important to understand the present invention that it is not.

A difference is also provided in the detection range distance of the human sensor 3 indoors and outdoors. It is not user-friendly if the unnatural posture of standing right in front of the door is forced when trying to enter the room from the outside. As a result of pursuing the optimum mode of human behavior, a distance is set such that a person is within reach of the outer opening/closing operation portion 13 . A person existing at this distance is a person standing with the intention of opening the sliding door 10 . When a person stands here, the sliding door 10 is slowly opened at a speed that does not pose a danger. Such specifications are set because the situation is different from automatic doors, in which rapid passage of people is prioritized. On the other hand, indoors, the distance at which the body enters the door frame 15 is set, but if the hand is extended, the action of a person who has a clear intention to open the sliding door 10 will be affected. It is a corresponding configuration.

(Second embodiment)
FIG. 8 is a front view of the automatic door of the second embodiment as seen from the outside, and FIG. 9 is a rear view of the automatic door of the second embodiment as seen from the inside. 2nd Embodiment is also a form of the sliding door 10. As shown in FIG. However, while the opening/closing operation portion in the first embodiment is a large lever, in the second embodiment, the opening/closing operation portion is a hand portion and has a simple structure. When the upper electric lock 21 and the lower electric lock 24 are unlocked and the outer human sensor 31 or the inner human sensor 32 detects that a body has entered within a predetermined range, the sliding door 10 is opened. It is the same as the first embodiment in that it is automatically opened, but the method of setting this range is different from the first embodiment as described below.

(Detection range of the human sensor of the second embodiment)
A detection range of the human sensor 3 of the second embodiment will be described. FIG. 10 is an explanatory diagram showing the detection range of the human sensor 3 when a person is outside the automatic door. A two-dot chain line indicates the detection range. In FIG. 10, the outside human sensor 31 detects that a person has entered within a range of 1.2 m from the door surface of the door. If the opening/closing operation part is a handle part, the detection range of the motion sensor 3 is set based on the distance from the door surface because the distance to reach the door means that one has to stand closer to the door. It is set.

FIG. 11 is an explanatory diagram showing the detection range of the human sensor 3 when a person is inside the automatic door. A two-dot chain line indicates the detection range. In FIG. 11, the inner human sensor 32 detects that a part of the hand is intruding within a range of 0.3 m from the door surface of the door. In the first embodiment, the detection range of the inside motion sensor 32 is defined in relation to the doorframe 15, but the doorframe 15 may be large or small. While the detection range in the first embodiment is set on the premise that the size of the door frame 15 and the optimum detection range generally match, in the second embodiment, absolute detection is performed regardless of the size of the door frame 15. The optimum detection range is set by numerical values.

(Third embodiment)
In the third embodiment shown in FIG. 12, the detection range of the human sensor 3 when a person is outside the automatic door is set differently from the second embodiment. However, the means for performing the opening/closing operation is the same large lever as in the first embodiment. The two-dot chain line drawn in FIG. 12 indicates the detection range, and the outside human sensor 31 detects a person only when a person enters within a range of 0.4 m from the door surface of the door. It is configured. FIG. 12 shows how the human sensor 3 responds by holding up a hand within a range of 0.4 m from the door surface. In a home that is frequently visited by visitors, it is common for the resident to manually unlock the thumb-turn from the inside and invite the visitor in. In such a situation, if the detection range is set to 1.2 m from the door surface of the door, the detection may be excessive and inconvenience may occur. For example, when the upper thumb-turn is unlocked but the lower thumb-turn is not yet unlocked, if the human sensor 3 detects a person and the door starts to open, an unnecessary load is applied to the drive mechanism. is applied. Therefore, in the third embodiment, the detection range is set within 0.4 m from the door surface of the door.
Thus, it is understood that it is appropriate to set the detection range within 1.2 m or within 0.4 m from the door surface according to the living conditions of the residents. The setting may be the setting at the time of product shipment, or may be configured so that the setting can be changed.

As described above, the automatic opening/closing door according to the embodiments of the present invention has been described in detail with reference to the drawings. Even if there is a change in the design of the scope, etc., it is included in the present invention. For example, the second embodiment may be provided with a large lever type operating portion. This is because the second embodiment is significant in that the detection range of the human sensor 3 is set by the numerical value of the distance from the door surface. Moreover, although the first embodiment and the second embodiment are both in the form of a sliding door, they may be constructed as hinged doors. As explained above, the door is opened slowly so that there is no danger, and Japanese houses are usually opened outward. If it is set within a large range such as within 1.2 m from the door surface of the door of the form, there is no problem. Furthermore, even if the inner human sensor 32 is not provided on the door frame 15, if the detection range is set in the area inside the door frame 15, it can be provided above the sliding door 10 in the same manner as the outer human sensor 31. good. The important thing is to set the detection range appropriately for both indoors and outdoors. Any sensor method can be used as long as this can be ensured.
It should be noted that each of the above-described embodiments can be combined by using each other's techniques unless there is a particular contradiction or problem in the purpose, configuration, or the like.
