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

  FIG. 1 shows a hinged door incorporating a human sensor according to an embodiment. As shown in FIG. 1, the hinged door 100 is attached to, for example, a hinged door main body 101 and a symmetrical position of the door pushing side surface 101 </ b> A and the door sliding side surface 101 </ b> B in the hinged door main body 101. And a lever handle 110 having the same.

  2 and 3 are enlarged views of the lever handle 110 according to the present embodiment. 2 is a view of the lever handle 110 as viewed from the front side, and FIG. 3 is a view of the lever handle 110 as viewed from the back side. As shown in FIGS. 2 and 3, the lever handle 110 has a base portion 110 b that is integrally provided with a square shaft 110 a that interlocks with the latch bolt 112. For the lever handle 110, for example, a die-cast alloy can be used.

  The base portion 110b of the lever handle 110 is provided with a window portion 110c on the front side. A substrate 113 on which an electronic circuit is mounted is accommodated inside the base portion 110b so as to face the window portion 110c. On the window portion 110c side of the substrate 113, a human sensor 114A and an illuminance sensor 114B (hereinafter also referred to as human / illuminance sensors 114A and 114B), a human detection light emitting diode (LED) 115, and illumination light emission A diode (LED) 116 is provided.

  The human detection LED 115 may be configured such that, for example, a red LED is lit or blinks. On the other hand, the illumination LED 116 may be configured such that, for example, a blue LED is lit (or flashes). Known sensors can be used as the human / illuminance sensors 114A and 114B. For example, the human sensor 114A may be a sensor using infrared rays, ultrasonic waves, visible light, or the like. Here, a sensor using infrared rays is suitable for the human sensor 114A. As shown in FIG. 2, for example, a protective panel 130 made of a translucent resin material is fitted in the window 110c.

  Further, as shown in FIG. 3, on the back side of the substrate 113, a battery 120 serving as a power source for driving the human / illuminance sensors 114A and 114B and the LEDs 115 and 116 is accommodated in the battery box 120A. For example, when the battery 120 and the substrate 113 are exchanged, it can be performed from the opening 110d provided in the base 110b of the lever handle 110 and opening in the extending direction of the handle portion. For example, the opening 110d may be sealed with a lid 110e made of a resin material in the same color as the lever handle 110.

  Further, on the back side of the substrate 113, for example, a determination unit 117 that controls lighting of the human detection LED 115 and the illumination LED 116 from a detection signal from the human sensor 114A and a detection signal from the illuminance sensor 114B is mounted. Also good. Note that in the case where the human detection LED 115 and the illumination LED 116 are used as a single LED, the determination unit 117 is set so that the detection signal from the human sensor 114A has priority over the detection signal from the illuminance sensor 114B. It is preferable to do. Therefore, in the case of the configuration in which the illumination LED 116 is also used as the person detection LED 115, even when the illumination LED 116 has been turned on first, the illumination LED 116 can be turned off and the person detection LED 115 can be turned on or blinked. Here, a known microcomputer (microcomputer) chip can be used for the determination unit 117.

  Further, the wiring 124 taken out from the back side of the substrate 113 and provided with the terminal 122 at the tip portion is electrically connected to the other lever handle (not shown) that makes a pair through the square shaft 110a.

  In addition, the window part 110c and the protection panel 130 provided on the front side of the lever handle 110 can be arbitrarily set in shape including color as long as the design is taken into consideration and the function is not impaired. . In addition, the shape (outer shape) shown in FIGS. 1 to 3 is only an example in the lever handle 110 itself, as long as the function as the lever handle is not impaired and the substrate 113, the battery box 120A, and the like can be accommodated. , Can be any shape.

  In the present embodiment, the lever handle 110 on the door pushing side and the lever handle (not shown) on the door sliding side have the same electrical configuration (specifications).

  In the present embodiment, the human / illuminance sensors 114A and 114B, the LEDs 115 and 116, the determination unit 117, and the battery 120 are housed inside the base 110b of the lever handle 110. Any or all of the parts except for may be incorporated inside the front and back surfaces of the hinged door main body 101. If it does in this way, since base 110b of lever handle 110 can be formed more compactly, the design nature of the base 101b can be improved. On the contrary, as shown in FIGS. 2 and 3, when all the electronic components described above are accommodated in the base 110b of the lever handle 110, the maintainability can be improved.

  For example, the human / illuminance sensors 114 </ b> A and 114 </ b> B may be provided at arbitrary positions inside the front and back surfaces of the hinged door main body 101 or the front and back materials. Thereby, the safety at the time of opening the hinged door 100 can be improved by being able to detect the approach of a person at a position according to the object of use.

(Human feeling when the surroundings are bright / Illumination sensor and operation explanation of each LED)
In FIG. 1, the door-holding side surface 101A is the indoor (indoor) side, and the door-drawing side surface 101B is the outdoor (outdoor) side.

  First, as shown in FIG. 4, a room where a certain level of brightness is secured is assumed. That is, in this case, in the illuminance sensor 114B, the illuminance exceeds the detection threshold value. Here, when the person 200 in the room approaches the door pressing side surface 101 </ b> A of the hinged door main body 101, the human sensor 114 </ b> A of the lever handle 110 detects the person 200. Thereafter, a hand is put out to the lever handle 110 and while the lever handle 110 is pressed, the hinged door body 101 is pushed away.

  At this time, as shown in FIG. 4, when there is no person on the door side, the human sensor 114A of the lever handle 110 on the door side does not detect a person. Therefore, the person detection LED 115 of the lever handle 110 on the door sliding side is not lit. In this case, as a modification, the human detection LED 115 provided on the lever handle 110 on the door-holding side may be set to light. Furthermore, in this case, it is more preferable that the lighting color of the person detection LED 154 on the door-holding side is set to green or the like. If it does in this way, the person 200 by the side of a door can open the hinged door 100 in comfort.

  As another modification, even if the human sensor 114A of the lever handle 110 on the door side does not detect a person, the person detection LED 115 on the door side is lit or blinked in red, for example. Also good. In this case, since the person detection LED 115 on the door sliding side lights up or flashes before the person detection sensor 114A on the door sliding side detects the person, that is, at a position farther from the hinged door body 101, The pusher person 200 can open the hinged door main body 101 with greater security. However, in any case, the human / illuminance sensors 114A and 114B are always activated as long as the switch is on.

  Note that the operation for turning off the person detection LED 115 on the door-holding side or door-closing side in each of the modifications described above is turned off when the detection signal from the human sensor 114A on the door-holding side is turned off.

  Next, as shown in FIG. 5, when a person 200 approaches the door pushing side surface 101 </ b> A of the hinged door main body 101 and another person 210 approaches the door pulling side surface 101 </ b> B of the hinged door main body 101 while trying to push the hinged door main body 101. Then, the human sensor 114A of the lever handle 110 on the doorway side detects this other person 210.

  At this time, the determination unit 117 in the lever handle 110 is configured so that both the human sensor 114A on the door-holding side surface 101A and the human sensor 114A on the door-holding side surface 101B have the person 200 on the door-holding side surface 101A of the hinged door body 101, When another person 210 standing on the doorway side surface 101B is detected at the same time, the person detection LED 115 of the lever handle 110 on the doorway side surface 101B is lit or blinked in red, for example. Thereby, it is possible to notify the other person 210 standing on the door side of the hinged door body 101 that the hinged door body 101 will be opened from now. Thereby, the other person 210 who stopped on the door sliding side of the hinged door main body 101 can prevent the collision with the hinged door main body 101 due to the opening of the hinged door main body 101 unexpectedly.

  In addition, when the person detection LED 115 on the door side is lit or blinking, the person detection LED 115 on the door side is also lit or monitored for monitoring the person 200 in synchronization with the person detection LED 115 on the door side. It may be blinked.

  Further, the operation for turning off the person detection LED 115 on the door side is based on the condition that the logical product (and) of the detection signal from the person sensor 114A on the door side and the signal detected by the person sensor 114A on the door side is a condition. Turns off when one of the detection signals is turned off.

(Other usage examples of human sensors and LEDs)
As another usage example of the lever handle 110 according to the present embodiment, an example in which an alarm for confirming the safety of a person who should be in the room can be notified outside or outdoors will be described.

  For example, when the determination unit 117 incorporated in the lever handle 110 does not detect a human detection signal from the human touch sensor 114A on the door-holding side for a predetermined time, the determination unit 117 lights or blinks the door-side human detection LED 115. You may let them. The predetermined time in this case can be set to an appropriate value such as about 12 to 24 hours. In this case, a lighting operation that indicates an abnormality to the outside, such as shortening the blinking interval of the human detection LED 115, is preferable. It should be noted that the above set time may be accumulated and held for the time during which the determination unit 117 does not receive the detection signal from the human touch sensor 114A on the door side (inside the room).

(Experience of human / illuminance sensor and each LED when the surroundings are dark)
Next, when the room is dark, specifically, when the illuminance around the lever handle 110 on the door pressing side surface 101A of the hinged door main body 101 is lower than a predetermined set value (threshold value), the determination unit 117 A detection signal for detecting that the illuminance falls below the threshold is received from the sensor 114B. In this state, as shown in FIG. 6, when a person 200 in the room approaches the door pressing side surface 101 </ b> A of the door main body 101, the human sensor 114 </ b> A of the lever handle 110 on the door pressing side surface 101 </ b> A detects the person 200. . Accordingly, the determination unit 117 transmits an ON signal to the illumination LED 116 because an AND condition of human detection by the human sensor 114A and detection of a decrease in illuminance by the illuminance sensor 114B is satisfied. By this ON signal, the lighting LED 116 on the door side (inside the room) is lit in blue.

  Thus, when the room 200 is dark and a person 200 in the room tries to open the hinged door body 101, the position of the hinged door body 101, that is, the position of the lever handle 110 can be easily recognized. It is possible to avoid the collision of 200 hinged door main body 101.

  In addition, the human / illuminance sensors 114A and 114B provided on the door handle 110 and the human / illuminance sensors 114A and 114B provided on the door handle 110 operate independently of each other. It may be set to. In this case, for example, the lighting LED 116 on the door sliding side (outdoor) may be turned on or off according to the ambient illuminance when a person approaches the door sliding side of the hinged door body 101.

  In the case where the person detection LED 115 and the illumination LED 116 are combined, when the illumination LED 116 is turned on, a person 200 in the room tries to open the hinged door main body 101, and another person 210 is located outside the hinged door main body 101. When stopped, that is, when the human touch sensors 114A on both the door-holding side and the door-to-door side detect the people 200 and 210, respectively, the red human detection LED 115 is turned on in preference to the blue illumination LED 116. do it.

  The hinged door with the built-in human sensor according to the present invention can notify the person on the back side that the hinged door will open from now on, and has high industrial applicability.
