  Further, in the elevator according to the present invention, the light source device can be a laser device arranged to output a line-shaped door closing warning display made up of a plurality of laser beams traveling left and right or up and down the entrance. According to the said structure, the users of the hall including the rushing user and the users in the car are not dazzling, and the rushing user can sufficiently see the laser beam at the entrance and exit, so the rushing action is highly suppressed. Can do.

  Moreover, the elevator which concerns on this invention can be equipped with the control apparatus which recognizes the door closing state of an elevator door and changes the form of a door closing warning display by controlling the action | operation of a light source device according to the said door closing state. According to this configuration, for example, the density and concentration of the closing warning display are set to be low before the start of closing, and the density and concentration of the closing warning display are set to be high at the start of closing. The impact of the display can be strengthened.

  Further, the elevator according to the present invention includes a mist ejection device that ejects mist at an open entrance and exit, and the light source device outputs a door closing warning display to the entrance and exit by projecting a predetermined image onto the sprayed mist. It can be set as the structure to do. According to the said structure, it becomes possible to output the door closing warning display which consists of arbitrary images by making a mist into a screen at the entrance / exit.

  In the elevator according to the present invention, the light source device may be configured to project an advertisement display image onto the sprayed mist or the closed elevator door. According to the said structure, a light source device can be used also for an advertisement.

  According to the elevator according to the present invention, it is possible to recognize that the elevator door is closed by appealing to the user's sight by outputting a door closing warning display to a doorway that is open when the elevator door is closed. , It is possible to highly suppress the act of rushing into the car.

For example, when the door closing button of the opening / closing button of the car door 15 is pressed, a closing command for the car door 15 is transmitted from the control device 22 to the car door opening / closing device, and the car door opening / closing device is activated to close the car door 15. To do.

  The hall 12 is a place where passengers get on and off the car 11, and is provided on a plurality of floors. In the landing 12, an opening is formed on the landing wall that separates the landing 12 and the hoistway to form an entrance 13 that coincides with the opening of the car 11 that moves up and down in the hoistway. There is a landing door 16. In general, a three-sided frame 17 is installed at the periphery of the opening of the hall 12, a hall call button 18 for registering the car 11 on the hall wall, and an indicator for displaying the arrival of the car 11. 19 is installed. The hall call button 18 and the like are connected to the control device 22 in the same manner as the car operation panel, and the operation signal is transmitted to the control device 22.

  The entrance / exit 13 is an entrance for getting on and off the car 11, that is, getting on the car 11 from the hall 12 or getting off the car 11 from the car 11, and when the car 11 stops at a predetermined position on the hall 12. In addition, the opening of the car 11 and the opening of the landing 12 coincide with each other. And when the opening part of the passenger car 11 and the opening part of the hall 12 coincide with each other and the elevator door 14 is opened, the passenger door 13 is opened and the passenger car 11 can get on and off.

  As described above, the elevator door 14 includes the car door 15 and the landing door 16 and is a door that opens and closes the entrance 13. In the example shown in FIG. 1, the elevator door 14 is a center open type (CO type) door, and the car door 15 and the landing door 16 each include two doors (panels). The side end portions of the two doors that come into contact with each other are bent into, for example, a U shape to form a door contact surface 23 (see FIG. 2). That is, the door contact surface 23 is a surface facing the two doors, and when the door contact surfaces 23 coincide with each other, the entrance 13 is fully closed.

  The elevator door 14 is opened and closed by a door opening / closing device installed in the car 11. Specifically, the car door 15 and the landing door 16 are configured to engage with each other when the car 11 stops at a predetermined stop position on the landing 12. This is a mechanism for opening and closing the landing door 16 engaged in conjunction. The present invention can also be applied to an elevator provided with a so-called side open type (SO type) door, and is not limited to an elevator provided with a CO type door.

  The light source device 20 is a device that outputs a door closing warning display 21 to the open entrance 13 when the elevator door 14 is closed. The door closing warning display 21 is a display for notifying the user that the elevator door 14 is closed in a state in which the entrance 13 is open, and warning the user not to get into the car 11. In the example of FIG. 1, a line-shaped door closing warning display 21 composed of a plurality of visible rays traveling to the left and right of the entrance 13 is output. More specifically, the door closing warning display 21 is emitted from the door contact surface 23 of the right car door 15 along the left / right direction (width direction) of the entrance / exit 13, that is, the opening / closing direction of the elevator door 14. 13 is formed by a plurality of visible rays existing at equal intervals from the upper part to the lower part.

  The light source device 20 is preferably a device that can output visible light with high directivity so that the visible light can be seen as a line that goes to the left and right of the entrance 13, and a laser that can output clear visible laser light such as red More preferably it is a device. A known laser device can be used as the laser device, but a small semiconductor laser capable of outputting red, green, blue, or multicolor laser beams is preferably used. It is also possible to install a laser device that outputs laser beams of different wavelengths to provide a line-shaped door warning display 21 having a different color.

  As shown in FIGS. 1 and 2, a plurality of light source devices 20 can be installed on the back side of the door contact surface 23 of the car door 15 corresponding to the number of laser beams. That is, the light source device 20 is installed in the car 15. Specifically, as shown in FIG. 2, a plurality of exit windows 24 are formed on the door contact surface 23, and the back surface of the door contact surface 23 and the outer surface of the car door 15 (on the landing door 16 side). Surface). The laser beam output from the light source device 20 goes straight in the width direction of the entrance 13 toward the facing door contact surface 23 through the emission window 24. The exit window 24 can be a simple through-hole, but can also have a configuration in which a transparent resin plate or the like is attached to the through-hole.

  Here, the timing when the door closing warning display 21 is output will be described. The door closing warning display 21 is output to the open doorway 13 when the elevator door 14 closes, that is, when the open doorway 13 is closed. Specifically, it can be set to output the door closing warning display 21 from the time when the door closing operation of the elevator door 14 is started until the door is fully closed. Alternatively, the door closing warning display 21 may be set to output a predetermined time before the door closing operation of the elevator door 14 is started. Here, the “predetermined time period” is just before the door closing operation of the elevator door 14 is started, and can be appropriately set according to the situation of the hall 12 or the like such as one to two seconds before.

  The light source device 20 outputs / stops the door closing warning display 21 under the control of the control device 22. That is, the control device 22 controls the opening / closing of the elevator door 14 and the operation of the light source device 20. Specifically, the light source device 20 is connected to the control device 22 and is operated at a timing inputted (registered) in advance to the control device 22. For example, when the door opening / closing button of the in-car operation panel is operated, the control device 22 outputs an operation command to the light source device 20 before outputting the door closing command to the car door opening / closing device, and starts closing the elevator door 14. The door closing warning display 21 can be output before a predetermined time. Alternatively, control can be performed so that the start timing of the door closing and the output start timing of the door closing warning display 21 are matched.

  The control device 22 can also recognize the door closing state of the elevator door 14 and control the operation of the light source device 20 so as to change the form of the door closing warning display 21 according to the door closing state. For example, only a part of the light source devices 20 is activated at the start of closing the door, and the number of lines is changed according to the closing state, such as increasing the number of laser beams by operating the light source devices 20 step by step with the closing of the door. Can do. Alternatively, the color of the line can be changed according to the closed state.

  As described above, the elevator 10 includes the light source device 20 that outputs the door closing warning display 21 to the entrance 13 that is open when the elevator door 14 is closed, so that the elevator door 14 appeals to the user's vision. It is possible to recognize that the door is closed, and it is possible to highly suppress the act of rushing into the car 11. That is, even when the elevator door 14 is opened, for example, a line-shaped closing warning display 21 composed of a plurality of laser beams is output to the entrance 13 so that many users can enter the entrance 13 with the display. Hesitate to pass.

  In the example shown in FIG. 1, the door closing warning display 21 composed of a plurality of laser beams traveling parallel to the left / right direction of the entrance / exit 13 has been described. It may consist of a laser beam that travels in parallel or a laser beam that travels diagonally rather than parallel to the left-right direction or the vertical direction of the entrance 13.

  For example, in the example shown in FIG. 3, the light source device 20 is provided on each of the upper and lower parts of the right car door 15. The upper light source device 20 is arranged to output visible light (laser light) toward the lower portion of the left car door 15 and the lower light source device 20 toward the upper portion of the left car door 15. Yes. According to the said structure, it is possible to output the grid | lattice (x-shaped) door closing warning display 21 which advances diagonally to the right and left of the entrance / exit 13. Further, the angle of the light source device 20 can be changed as the elevator door 14 is closed. For example, with respect to the upper light source device 20, a long exit window is formed on the door contact surface along the vertical direction, and in conjunction with the closing operation of the elevator door 14, the light source device 20 faces further downward from the initial state (at the start of closing). The light source device 20 can be installed on a swing base that changes the angle (the lower light source device 20 is installed on a swing base that changes the angle so as to face upward).

  In the above description, the light source device 20 is installed on the back side of the door contact surface 23 of the car door 15. However, the installation location of the light source device 20 is not limited to this, and the door closing warning display 21 is displayed at the entrance 13. Can be installed in a place where output is possible. For example, the light source device 20 may be installed on the door frame, wall surface, ceiling, or landing 12 of the car 11.

  In the above description, a plurality of light source devices 20 are provided. However, a configuration including one light source device 20 may be used. For example, one flushing light that irradiates flushing light or the like from the inside of the car 11 toward the entrance / exit 13 may be installed on the wall surface or ceiling of the car 11 as the light source device 20. Under the control of the control device 22, the flashing light flashing mode or the like can be changed according to the closed state of the elevator door 14.

  In addition, by painting the hall wall of the hall 12 in the same color as the color of visible light output from the light source device 20, the door closing warning display 21 can be prevented from being seen from within the car 11. it can.

The elevator 30 will be described with reference to FIG. In addition, about the component same as the elevator 10, the same code | symbol is attached | subjected and the overlapping description is abbreviate | omitted.

  As shown in FIG. 4, the elevator 30 is characterized in that a mist spraying device 36 is mounted on a car 31 and a light source device 35 is provided on the landing 12. The timing at which the door closing warning display 41 is output by the light source device 35 can be set in the same manner as in the elevator 10. The elevator 30 also includes an elevator door 34 including a car door 33 and a landing door 16. The car door 33 is a general door on which the light source device 20 is not installed.

  The light source device 35 outputs a predetermined image on the mist 40 sprayed by the mist spraying device 36 to output a door closing warning display 41 to the entrance 13. That is, as the light source device 35, a projection device (projector) that displays the door closing warning display 41 using the mist 40 present at the entrance 13 as a screen can be used. A general CRT projector or a liquid crystal projector can be used as the projector. Alternatively, the light source device 35 is a light source that emits visible light (incandescent lamp, fluorescent lamp, LED, etc.), a so-called pattern cutter that changes the light from the light source to a predetermined image (shape), and narrows the light emitted from the pattern cutter as necessary. It may have a lens.

  The light source device 35 is installed at a position where a predetermined image can be projected onto the mist 40. For example, as shown in FIG. 4, the light source device 35 can be installed on the ceiling of the hall 12. Alternatively, the light source device 35 may be installed on the ceiling or wall surface of the car 11 to project an image from the car 11.

  The mist spraying device 36 is a device that sprays the mist 40 onto the entrance 13. As the mist spraying device 36, a general device that generates mist 40 by compressing water and spraying it from a fine nozzle can be used.
