  However, in the technique described in Patent Document 2, the light emitter is provided on the door push side, and the human sensor is provided on the opposite side (door pull side) of the door push side, and the door is opened to another person on the door pull side. It is not a configuration that informs that. In addition, various sensors and light sources require a power source, and when these sensors, power sources, etc. are incorporated into a door knob or a door handle, maintenance for replacing a power source (for example, a battery), and maintenance for disconnection of wiring are required. There is a problem that the work of becomes complicated. Further, in a configuration in which an electronic device is incorporated into a door knob or the like, there is a problem that the form of the door is limited to a hinged door.

  The present invention solves the above-mentioned conventional problems, and when trying to open a door, it is possible to inform a person on the back side of the door that the door is about to open and to facilitate maintenance work. The purpose is to do.

  In order to achieve the above-mentioned object, the present invention provides a door device in which when a person confronts the opposite side to the side to be opened first, the door is provided to the person on the opposite side. It will be configured to notify by light, etc.

  Specifically, the present invention is directed to a door device, and has taken the following solving means.

  That is, a first aspect of the present invention is a door device in which a motion sensor is built-in, and a first surface that a person who wants to open opposes first and a second surface opposite to the first surface. And a sensor unit provided on the door body. The sensor unit is provided on the first surface side and includes a first person detecting means for detecting an approach of a person, and a second person detecting means provided on the second surface side for detecting an approach of a person, A determination means for determining the detection signals from the first person detection means and the second person detection means, a first light source means provided on the first surface side, and a first light source means provided on the second surface side. 2 light source means, a first person detecting means, a second person detecting means, a determining means, a power source means for supplying electric power to the first light source means and the second light source means respectively via wiring. ing. The determination means actuates at least the second light source means when receiving the detection signals from both the first person detection means and the second person detection means.

  According to this, in the case where the door device does not have a daylighting section, that is, in the case where the person on the opposite side of the door cannot be confirmed, the second surface side on the back side of the first surface side to be opened When there is another person, the second light source means provided in the sensor unit is turned on, so that the person on the second surface side can be informed that the door is about to open. Therefore, when the door is opened unexpectedly, it is possible to prevent a collision with a person on the opposite side of the door. Moreover, since the sensor unit accommodating the power supply means including the detection means, the determination means and the wiring is used, the wiring work is unnecessary and the disconnection due to the use is less likely to occur. Further, if a battery is used as the power source means, maintenance work for battery replacement becomes easy.

  In a second aspect based on the first aspect, when the determination means receives the detection signal of the first human detection means and does not receive the detection signal of the second human detection means, One light source means may be activated.

  According to this, when the person is detected only on the side of the first surface that tries to open the door, and the person on the side of the second surface behind the side is not detected, the light source means on the side of the first surface is detected. By activating, the person on the first side can confirm the safety of the back side and can open the door with confidence.

    In a third aspect based on the first or second aspect, the sensor unit may be inserted from the front edge or the upper edge of the door body.

(One embodiment)
An embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is an exploded perspective view of a main part of a door device including a motion sensor according to an embodiment. As shown in FIG. 1, the door device 100 is attached, for example, to a door main body 101 which is a hinged door, and at symmetrical positions of the door main body 101 on the door pushing side and the door pulling side, and the latch bolt 112 is attached to the door tip side edge 101a. And a sensor unit 150 to be inserted from the front edge 101a of the door body 101. Here, the door pushing side of the door body 101 is the first surface, and the door pulling side is the second surface. Further, the sensor unit 150 is inserted between the front surface material and the rear surface material of the door body 101 and in the upper portion of the lever handle 110. However, depending on the specifications of the door main body 101, for example, the sensor unit 150 may be attached to the lower portion of the lever handle 110 in the door end side edge 101a in consideration of its design. Further, the sensor unit 150 may be inserted from the upper edge 101b instead of the door edge side edge 101a of the door body 101.

  The sensor unit 150 is housed inside a housing 152 having a lid 151. For the lid 151 and the casing 152, for example, a metal plate or a hard resin material can be used. On both side surfaces of the housing 152 on the door pushing side and the door pulling side, a human sensor and an illuminance sensor (hereinafter, referred to as human presence / illuminance sensor) 153, a human detection light emitting diode (LED) are provided at positions facing each other on both sides. : Light Emitting Diode) 154 and an illumination light emitting diode (LED) 155 are provided (see FIG. 3). Here, the human detection LED 154 may be configured such that, for example, a red LED is turned on or blinks. On the other hand, as the illumination LED 155, for example, a blue LED may be turned on (or blinking). As the human presence / illuminance sensor 153, known sensors can be used. For example, the motion sensor may be a sensor that uses infrared rays, ultrasonic waves, visible light, or the like. Here, a human sensor using infrared rays is suitable.

  First and second window portions 101c are provided on the front and back surfaces of the door body 101 in correspondence with the human / illuminance sensor 153. Similarly, the second window portion 101d is provided on the front and back materials in correspondence with the person detection LED 154 and the illumination LED 155. For example, white translucent resin materials 120 and 122 are fitted into the first window portion 101c and the second window portion 101d, respectively. The human sensor and the illuminance sensor are separate electronic devices, but if an IC package in which these are integrated is adopted, as shown in FIG. 1, a compact window portion 101c and the same are fitted. The translucent resin material 120 can be used.

  In addition, from the lid 151 of the sensor unit 150, a switch 156 for turning on / off the power source and a cap 157a of a battery 157 that is a power source are exposed at the door-edge-side edge 101a.

  As shown in FIG. 2, when the sensor unit 150 is inserted into the door body 101 and the lid 151 thereof is held by the door edge side small opening 101a by a screw or the like, the protective cover 160 made of, for example, a resin material is 151 is detachably attached to the front edge 101a so as to cover 151.

  FIG. 3 shows a schematic circuit configuration of the sensor unit 150 according to this embodiment. In FIG. 3, the same reference numerals are given to the constituent members and constituent elements shown in FIG. As shown in FIG. 3, the sensor unit 150 has a human detection LED 154, a lighting LED 155, and a human presence / illuminance sensor 153 for two pairs, one for the door push side and the other for the door pull side. Each of these is electrically connected to the determination unit 158 via the wiring 159.

  In the case where one LED serves as both the human detection LED 154 and the illumination LED 155, the determination unit 158 is provided so that the detection signal from the human sensor for detecting a person has priority over the detection signal from the illuminance sensor. It is preferable to provide. Therefore, when the illumination LED 155 is also used as the person detection LED 154, the illumination LED 155 can be turned off and the person detection LED 154 can be turned on or blinking even if the illumination LED 155 is turned on first. Here, as the determination unit 158, a known microcomputer chip can be used.

  In the present embodiment, the hinged door is used for the door body 101 of the door apparatus 100, but the invention is not limited to the hinged door. That is, the door device 100 according to the present embodiment is not applied to the sliding door device because the sensors and the light source means are not provided on the member (part) protruding from the door body 101 such as the lever handle 110. It is possible.

  In addition, the sensor unit 150 according to the present embodiment can operate independently, that is, by the sensor unit 150 itself, and new wiring processing or the like is unnecessary at the time of mounting. Therefore, the sensor unit 150 can be attached later even to the door body 101 where the sensor unit 150 is not initially provided.

  The planar shapes of the semitransparent resin material 120 that transmits a signal transmitted or received by the human presence / illuminance sensor 153 and the semitransparent resin material 122 that transmits the light emitted from the human detection LED 154 and the illumination LEDs 155 are both planar. Although the shape is rectangular, the invention is not limited to this, and it is possible to change the colors and the like as long as the functions of the respective elements are not impaired, and each of them can have a design. For example, by changing the colors and shapes of the semitransparent resin materials 120 and 122 on the door pushing side surface and the door pulling side surface, each sign of the door pushing side and the door pulling side is given a distinctiveness (identification). You can

(Explanation of motion / illuminance sensor and LED operation when the surroundings are bright)
In FIG. 1, the right (front) surface of the door body 101 is the door push side, and the back surface is the door pull side. Further, the door push side may be an indoor (indoor) and the door pull side may be an outdoor (outdoor).

  First, as shown in FIG. 4, it is assumed that the room has a certain level of brightness. That is, in this case, the illuminance exceeds the detection threshold in the human / illuminance sensor 153. Here, when the person 200 in the room approaches the door pushing side of the door body 101, the human presence / illuminance sensor 153 on the door pushing side of the sensor unit 150 detects the person 200. After that, the user extends his or her hand to the lever handle 110 and tries to push the door body 101 away while pushing the lever handle 110.

  At this time, as shown in FIG. 4, when there is no person on the side of the door, the motion / illuminance sensor 113 of the sensor unit 150 on the side of the door does not detect the person. Therefore, the person detection LED 154 of the door-side sensor unit 150 does not light up. In this case, as a modification, the person detection LED 154 provided in the sensor unit 150 on the door pushing side may be set to be turned on. Further, in this case, it is more preferable to set the lighting color of the person detection LED 154 on the door pushing side to green or the like. In this way, the person 200 on the door push side can open the door body 101 with peace of mind.

  Further, as another modified example, even when the motion / illuminance sensor 113 of the door-side sensor unit 150 does not detect a person, the door-side human detection LED 154 is lit or blinks, for example, in red. You may let me. In this way, the door-side human detection LED 154 lights up or blinks before the door-side human presence / illuminance sensor 153 detects a person, that is, at a position farther from the door body 101. The person 200 on the door push side can open the door body 101 with even more peace of mind. However, in any case, the various sensors 153 are always activated as long as the switch is in the ON state.

  The operation of turning off the person detection LED 154 on the door push side or the door pull side in each of the above-described modifications turns off when the person detection signal from the human presence / illuminance sensor 153 on the door push side is in the off state.

  Next, as shown in FIG. 5, while the person 200 approaches the door pushing side of the door body 101 and tries to push the door body 101, another person 210 is placed on the opposite side (door pulling side) of the sensor unit 150 to the door pushing side. When the person approaches, the human presence / illuminance sensor 153 on the door side of the sensor unit 150 detects the other person 210.

  At this time, the determination unit 158 of the sensor unit 150 determines that the human-side illumination / illuminance sensor 153 on the door push side and the human-side illumination / illuminance sensor 153 on the door slide side are both the person 200 on the door push side of the door body 101 and the door 200. When the other person 210 standing on the pull side is detected at the same time, the person detection LED 154 on the door pull side of the sensor unit 150 is lit or blinks in red, for example. As a result, it is possible to notify the other person 210 standing on the door side of the door body 101 that the door body 101 will be opened. Thus, it is possible to prevent the other person 210 standing on the door pulling side of the door body 101 from colliding with the door body 101 due to the door body 101 opening unexpectedly.

  In addition, when the person detection LED 154 on the door pull side is lit or blinking, the person detection LED 154 on the door push side is also turned on or used for monitoring the person 200 in synchronization with the person detection LED 154 on the door pull side. It may blink.

  Further, the turning-off operation of the person detection LED 154 on the door pull side is conditional on the logical product (and) of the detection signal from the person / illuminance sensor 153 on the door push side and the detection signal from the person / illuminance sensor 153 on the door pull side. Therefore, it is turned off when either one of the detection signals is in the off state.

  Further, in the present embodiment, even if the door device 100 is a sliding door, the motions of the motion sensor and each LED are the same.

(Other usage examples of human sensor and LEDs)
As another usage example of the sensor unit 150 according to the present embodiment, an example in which an alarm can be given to the outside or the outside as an alarm for confirming the safety of a person who is supposed to be indoors will be described.

  For example, when the determination unit 158 included in the sensor unit 150 does not detect the human detection signal from the human-motion / illuminance sensor 153 on the door push side for a predetermined period of time or longer, the person detection LED 154 on the door pull side is turned on. Alternatively, it may blink. The predetermined time in this case can be set to an appropriate value, for example, about 12 to 24 hours. In this case, it is preferable to perform a lighting operation indicating an external abnormality such as making the blinking interval of the human detection LED 154 shorter than usual. It should be noted that the above-mentioned set time may be held by accumulating the time during which the determination unit 158 does not receive the human detection signal from the human-motion / illuminance sensor 153 on the door push side (inside the room).

(Explanation of motion / illuminance sensor and LED operation when the surroundings are dark)
Next, when the room is dark, specifically, when the illuminance around the door push side of the sensor unit 150 of the door body 101 is lower than a predetermined set value (threshold value), the determination unit 158 determines that A detection signal for detecting that the illuminance is below the threshold value is received from the illuminance sensor unit of the illuminance sensor 153. In this state, as shown in FIG. 6, when the person 200 in the room approaches the door pushing side of the door body 101, the person detecting sensor unit of the door pushing side of the sensor unit 150 detects the person detecting sensor portion of the illuminance sensor 153. To detect. As a result, the determination unit 158 transmits the ON signal to the illumination LED 155 because the and condition of the human detection / illuminance sensor 153 detection of a person and the detection of a decrease in illuminance is satisfied. By this ON signal, the illumination LED 155 on the door pushing side (inside the room) lights up in blue.

  In this way, when the person 200 who is in the room tries to open the door body 101 in a dark room, the position of the door body 101 can be easily recognized. Collisions can be avoided.

  Further, the human-motion / illuminance sensor 153 on the door push side and the human-sensation / illuminance sensor 153 on the door pull side, which are provided in the sensor unit 150, may be set to operate independently of each other. In this case, for example, the door-side (outdoor side) illumination LED 155 may be turned on or off depending on the illuminance of the surroundings when a person approaches the door-side of the door body 101.

  In the case of the configuration in which the person detection LED 154 and the illumination LED 155 are combined, the person 200 inside the room tries to open the door body 101 when the illumination LED 155 is turned on, and another person 210 is outside the door body 101. When stopped, that is, when the human presence / illuminance sensors 153 on both the door push side and the door pull side detect the persons 200 and 210, respectively, the red person detection LED 154 is turned on in preference to the blue illumination LED 155. It should be in a state.

  Further, in the present embodiment, even if the door device 100 is a sliding door, the operations of the illuminance sensor and each LED are the same.

  The door device incorporating the motion sensor according to the present invention can notify the person on the back side that the door is about to open, and besides, the maintenance work is easy and the industrial applicability is high. high.
