The color of the laser beam 11 can be a color that attracts attention, such as red or orange. Moreover, the light emission part 10 can emit the laser beam 11 toward the irradiation range as shown in FIG. 1, and can alert the user who is near the entrance / exit across the entire width of the entrance / exit.

  In the prior art, the flashing light itself is recognized by the user. On the other hand, the first embodiment has a technical feature in that the user does not recognize the flashing light itself but recognizes the reflected light applied to a part of the body. In this way, the user can specifically determine the portion that may be pulled in by looking at the reflected light of the laser beam 11 emitted from the light emitting unit 10, such as separating the portion from the door 3. It can also be supported.

  FIG. 2 is an explanatory view showing an irradiation area of laser light emitted by the warning device at the time of opening and closing of the elevator door according to Embodiment 1 of the present invention, and shows an irradiation area with respect to a left and right double door. Normally, when a hand or the like is drawn into the gap between the door 3 and the doorway pillar 1, the user is in the vicinity of the center of the doorway and is standing in the immediate vicinity of the door, with the hand touching the door. It is possible that there is.

  In this state, the irradiation position of the laser beam 11 in the first embodiment is separated from the surface of the door 3 by about 50 mm to 100 mm in order to make the user recognize the laser beam 11 irradiated to the hand touching the door. Is set to the correct position. Further, as shown in FIG. 1, the irradiation range of the laser beam 11 covers the entire width of the entrance / exit as the width direction, and considers the height of the user as the height direction, for example, 1800 mm. It is set to cover the following areas.

  Moreover, FIG. 3 is another explanatory drawing which shows the irradiation area | region of the laser beam light-emitted by the alerting device at the time of the door opening / closing of the elevator in Embodiment 1 of this invention, and is an irradiation area | region with respect to the door of a two-door single opening Is shown. In the case of two-door single door opening or the like, there is a possibility of being drawn between the high-speed door 3a and the low-speed door 3b.

  Even in such a case, the full width of the entrance / exit is covered, and as shown in FIG. 3, by setting the irradiation area at a position about 50 mm to 100 mm away from the surface of the high speed door 3a, It is possible to reliably alert the drawn-in places at both the low-speed door 3b and between the low-speed door 3b and the entrance / exit column 1.

  The reflected light by the visible light (laser light 11) employed in the present invention does not necessarily have to be a “line” as illustrated in FIG. 2 or FIG. 4 and 5 are explanatory views showing specific examples of reflected light by visible light used in the elevator door opening / closing alerting device according to Embodiment 1 of the present invention.

  In order to call attention to the user more visually, it is possible to adopt alerts by letters as shown in FIG. 4, and it is also possible to adopt alerts by means of marks as shown in FIG. It is. Furthermore, although not shown, it is also possible to employ a moving image.

  Thus, it becomes possible to raise the alerting effect to a user by adopting appropriate visible light according to conditions, such as an installation place of an elevator. Furthermore, in order to enhance the alerting effect to the user, it is also possible to link with a voice announcement such as “door opens” when opening and closing the door.

  Next, in the first embodiment, a specific series of attention calling operations performed in conjunction with the opening and closing of the door will be described using a flowchart. FIG. 6 is a flowchart showing a series of alerting processing operations during door opening and closing operations by control unit 20 in the elevator door opening and closing alerting device according to Embodiment 1 of the present invention.

  First, a series of operations during the door opening operation will be described based on Steps S601 to S605. First, in step S601, the control unit 20 determines whether a door opening scheduled signal is received as door opening / closing operation information from the door controller 30 that performs opening / closing control of the elevator door.

  And when the door opening plan signal is received by this step S601, the control part 20 progresses to step S602, and implements an audio | voice announcement in order to notify a user that door opening operation | movement is started. The control unit 20 can output such a voice announcement via a voice output unit not shown in FIG. Further, the control unit 20 can perform the alerting process by executing only the subsequent visible light irradiation without performing the voice announcement.

  Next, in step S603, the control unit 20 causes the light emitting unit 10 to flash and emit visible light from a predetermined time before starting the door opening operation (for example, from about 2 seconds before the door is opened).

  Next, in step S604, the control unit 20 determines whether or not the door opening operation has started by determining whether or not a door opening operation start signal has been received as door opening / closing operation information from the door controller 30. to decide. When the door opening operation start signal is received in step S604, the control unit 20 proceeds to step S605 and ends the blinking irradiation of visible light from the light emitting unit 10.

  Through such a series of processes, the control unit 20 causes the light emitting unit 10 to flash and irradiate a predetermined irradiation range with visible light from a predetermined time before starting the door opening operation until the door opening operation is completed. Thus, it is possible to call attention to the customers near the door.

  Note that the period of flashing visible light is not limited to a period from a predetermined time before the door opening operation is started until the door opening operation is completed, and a predetermined time elapses after the door opening operation starts. Until then, blinking irradiation may be continued.

  Next, a series of operations during the door closing operation will be described based on Steps S611 to S615. First, in step S611, the control unit 20 determines whether or not a door closing operation start signal is received as door opening / closing operation information from the door controller 30 that performs opening / closing control of the elevator door.

  When the door closing operation start signal is received in step S611, the control unit 20 proceeds to step S612 and performs a voice announcement to inform the user that the door closing operation is started. The control unit 20 can output such a voice announcement via a voice output unit not shown in FIG. Further, the control unit 20 can perform the alerting process by executing only the subsequent visible light irradiation without performing the voice announcement.

  Next, in step S613, the control unit 20 causes the light emitting unit 10 to flash visible light in conjunction with the door closing operation.

  Next, in step S614, the control unit 20 determines whether or not the door closing operation is completed by determining whether or not a door closing operation completion signal is received as door opening / closing operation information from the door controller 30. to decide. And when this door closing operation completion signal is received by this step S614, the control part 20 progresses to step S615, and complete | finishes blinking irradiation of visible light from the light emission part 10. FIG.

  Through such a series of processes, the control unit 20 alerts the user near the door by flashing visible light in a predetermined irradiation range from the light emitting unit 10 in conjunction with the door closing operation. It can be performed.

  In addition, the light emission part 10 in the alerting device at the time of the door opening / closing of the elevator demonstrated in this Embodiment 1 may be installed in either the car side of a doorway or a landing side, and may be installed in both.

  As described above, according to the first embodiment, the door that opens and closes the user by irradiating the predetermined irradiation range near the entrance with visible light in conjunction with the door opening and closing operation. It is possible to visually check the reflected light applied to the part of the body that may interfere with the body. This reflected light allows the user to specifically identify the part that may be pulled in or pinched, and to take the part away from the door that opens and closes. It becomes.

  As a result, an elevator alerting device and an elevator door alerting method that can enhance the alerting effect for passengers and prevent disasters associated with elevator door opening and closing operations can be realized. Can do.

  In particular, in the first embodiment, as a predetermined irradiation range in the vicinity of the entrance / exit, a region 50 mm to 100 mm away from the surface of the door performing the opening / closing operation is defined as an example and drawn in over the width direction of the elevator entrance / exit An area that has a high possibility of being caught or pinched is identified. By irradiating such an area with visible light, the user can be expected to leave the area. Furthermore, even if there is a part of the body near the door unintentionally (knowingly and without knowing it), by visually checking the reflected light of the irradiated visible light, the user can move to a position near the door. You can recognize that you are in the area, and you can expect the effect of leaving quickly.

  In the above description, the case of flashing visible light has been described. However, it is not always necessary to perform flashing irradiation, and an equivalent effect can be realized by performing lighting irradiation as necessary. It is also possible to change the blinking pattern of visible light to be irradiated according to the installation location and time zone.
