BACKGROUND OF THE INVENTION
The present invention relates to a door device provided in an elevator hall of a building.
[0002]
[Prior art]
FIG. 4 shows an external view of the elevator hall in the building, and FIG. 5 shows a cross-sectional view taken along line CC in FIG. 4, and the wall 1 of the elevator hall as shown in FIG. An opening 2 for getting on and off the elevator is formed. A three-way frame 3 is installed inside the opening 2.
[0003]
As shown in FIG. 4, the three-way frame 3 includes a pair of standing frames 5 that cover both sides of the opening 2, and an upper frame 6 that is disposed between the upper ends of these standing frames 5 and covers the upper portion of the opening 2. It is configured in a gate shape.
[0004]
On the back side of the three-way frame 3, for example, double-open door panels 8a and 8b that open and close the opening 2 are provided. These door panels 8a and 8b are slidably disposed on a sill 10 installed on the back side of the wall 1 so as to be substantially flush with the floor 9 of the elevator hall, and an elevator car (not shown) is installed in the elevator. When landing on the landing, the opening 2 is opened by moving along the longitudinal direction of the sill 10 in conjunction with the car door of the car.
[0005]
On the front surface of the wall 1, there are provided a position indicator lamp 12 for displaying the operation position of the car, and an arrival indicator lamp 13 that lights up immediately before the car arrives at the elevator hall and displays the arrival of the car. A sound generator 14 for notifying the arrival of the car by sound or voice is incorporated outside the upper frame 6 of the three-way frame 3.
[0006]
A passenger of the elevator recognizes the arrival of the car based on information from the position indicator lamp 12, the arrival indicator lamp 13, and the sound generator 14, and enters the car after the door panels 8a and 8b are opened.
[0007]
[Problems to be solved by the invention]
The elevator passenger recognizes the arrival of the car based on the information from the position indicator lamp 12, the arrival indicator lamp 13, and the sound generator 14 as described above, but exactly when the door panels 8a and 8b are opened. It cannot be judged.
[0008]
For this reason, it is assumed that the passenger car has arrived, and the elevator user is too close to the door panels 8a and 8b to collide with each other, or when it is crowded, it is pushed by other passengers and the door panels 8a and 8b and the three-way frame. There is a risk that a finger is caught in a gap (a portion shown in FIG. 5) between the three standing frames 5 and an injury is caused.
[0009]
And when such a trouble occurs, the smooth boarding / alighting with respect to a passenger car will be inhibited, and the operation efficiency of an elevator will fall.
[0010]
The present invention has been made paying attention to such points, and the purpose of the present invention is to pay attention to the opening of the door panels 8a and 8b prior to the arrival of the car and the opening of the door panels 8a and 8b. It is an object of the present invention to provide an elevator hall door device that can prompt an elevator user to prevent troubles from occurring.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to FIGS. In addition, the same code | symbol is attached | subjected to the part corresponding to the conventional structure, and the overlapping description is abbreviate | omitted.
[0018]
FIG. 1 shows a first embodiment, and FIG. 2 shows a cross-sectional view taken along line YY in FIG. In this embodiment, a straight-tube cold-cathode fluorescent lamp 20 as a light source and an inverter 21 for lighting it are provided outside the vertical frames 5 in the three-way frame 3.
[0019]
The cold cathode fluorescent lamp 20 is connected to an inverter 21 by wiring, and the inverter 21 is further connected to a control panel 22 for controlling the operation of the elevator, and the control panel 22 controls turning on / off of the cold cathode fluorescent lamp 20. It is like that.
[0020]
The cold cathode fluorescent lamp 20 is applied to a translucent discharge vessel having a diameter of about 1 to 6 mm, a pair of cold cathodes (not shown) sealed at both ends of the discharge vessel, and the inner surface of the discharge vessel. And a discharge medium (not shown) sealed in a discharge vessel.
[0021]
The cold cathode fluorescent lamp 20 has a long life because the cathode emits light without being heated, and the life is influenced by the number of times of turning on / off like a normal fluorescent lamp (hot cathode fluorescent lamp). Of course, when a voltage is further applied, it is turned on immediately and there is no time delay until light emission.
[0022]
The cold cathode fluorescent lamp 20 is arranged outside the upright frame 5 along the longitudinal direction thereof. As shown in FIG. 2, a reflector 24 is provided on the opposite side of the outer surface of the upright frame 5 with the cold cathode fluorescent lamp 20 as a boundary, facing the cold cathode fluorescent lamp 20, and on the end faces of the door panels 8a and 8b. A reflecting plate 25 is attached to face the back surface of the upright frame 5, and the light when the cold cathode fluorescent lamp 20 is turned on by the reflecting plates 24 and 25 enters the gap a between the upright frame 5 and the door panels 8 a and 8 b. The light is further guided toward the surfaces of the door panels 8a and 8b.
[0023]
In addition, 26 shown in FIG. 1 is a car call button provided on the front surface of the wall 1 of the elevator hall.
[0024]
Next, the operation will be described.
A passenger of the elevator operates the car call button 26 and waits for the arrival of the car. At this time, the position indicator lamp 12, arrival indicator lamp 13 and sound generator 14 inform the passengers of the elevator about the moving situation of the car.
[0025]
Then, after the car arrives at the elevator hall and the door panels 8a and 8b are opened, the car enters the car. Prior to the arrival of the car, the control is performed, for example, 2-3 seconds before arrival. Lighting of the cold cathode fluorescent lamp 20 outside the vertical frame 5 is controlled via an inverter 21 by an electrical signal from the panel 22.
[0026]
As shown in FIG. 2, the light emitted from the cold cathode fluorescent lamp 20 is guided to the gap a between the standing frame 5 and the door panel 8a (8b) by the reflectors 24 and 25, and from the gap a to the door panel 8a. , 8b from the lateral direction.
[0027]
Due to this irradiation, the surfaces of the door panels 8a and 8b are brightly illuminated. Therefore, a customer who waits for the arrival of the car at the elevator hall increases his attention to the door panels 8a and 8b due to visual stimulation by the light.
[0028]
Therefore, the elevator user is too close to the door panels 8a and 8b to collide with each other, or is pushed by another user at the time of congestion or the like, and the gap between the door panels 8a and 8b and the standing frame 5 of the three-way frame 3 There is no risk of injury from a finger in a, and the user waits for the door panels 8a and 8b to open in order in front of the door panels 8a and 8b.
[0029]
Then, after the car arrives, the door panels 8a and 8b are completely opened, and the user gets into the car. Then, the cold cathode fluorescent lamp 20 is turned off by the control of the control panel 22, and is turned off. Thereafter, the door panels 8a and 8b are closed, and the car is moved toward the destination floor.
[0030]
Thus, before the door panels 8a and 8b are opened, the surface of the door panels 8a and 8b can be brightly illuminated with the cold cathode fluorescent lamp 20 to prompt the user to pay attention to the door panels 8a and 8b. Therefore, it is possible to prevent the trouble of the vehicle from occurring and allow the passengers of the elevator to smoothly ride in the car. Therefore, it is possible to achieve efficient operation without causing a decrease in the operation efficiency of the elevator.
[0031]
The cold cathode fluorescent lamp 20 as a light source for illuminating the surfaces of the door panels 8a and 8b has a diameter of about 1 to 6 mm and is very small compared with a normal fluorescent lamp, and therefore, a narrow space outside the upright frame 5. It can be easily installed even inside. Therefore, the present invention can be applied to an existing elevator by incorporating the cold cathode fluorescent lamp 20 without particularly changing the layout or the like.
[0032]
In addition, the cold cathode fluorescent lamp 20 has a much longer life than ordinary fluorescent lamps. Therefore, the replacement period can be greatly extended, and maintenance is facilitated. Further, the cold cathode fluorescent lamp 20 does not have an irregular blinking operation at the time of lighting as in a normal fluorescent lamp, and can be turned on immediately. For this reason, the surfaces of the door panels 8a and 8b are accurately illuminated without a sense of incongruity. be able to.
[0033]
FIG. 3 shows a second embodiment. FIG. 3 is a diagram of a section corresponding to the cross section along the line BB in FIG. 1. In this embodiment, a straight-tube cold cathode fluorescent lamp 20 as a light source is provided outside the upper frame 6 in the three-way frame 3. The upper frame 6 is provided along the longitudinal direction.
[0034]
And the light at the time of lighting of this cold cathode fluorescent lamp 20 is guide | induced to the clearance gap a between the upper frame 6 and the door panel 8a (8b) by the reflecting plates 31 and 32, and the light is further on the door panel 8a (8b). It is irradiated from above toward the surface.
[0035]
Even in such a configuration, since the surface of the door panel 8a (8b) is brightly illuminated by the lighting of the cold cathode fluorescent lamp 20, the light can urge the user to pay attention to the door panels 8a and 8b. The same effects as in the embodiment are achieved.
[0036]
The cold cathode fluorescent lamp is provided outside the vertical frame as in the first embodiment, and the cold cathode fluorescent lamp is provided outside the upper frame as in the second embodiment. Thus, it is possible to adopt a form in which the surface of the door panel is illuminated from the lateral direction and the upward direction.
[0037]
Further, the cold cathode fluorescent lamp may be blinking in addition to continuous lighting during lighting control. In this case, since the surface of the door panel is intermittently illuminated, attention to the door panel can be urged more strongly.
[0038]
In addition, the light source provided outside the standing frame and the upper frame is configured by combining multiple cold cathode fluorescent lamps with different emission colors, and the multiple cold cathode fluorescent lamps are alternately lit when controlling lighting. It is also possible to do. In this case, the surface of the door panel is alternately illuminated with different colors, so that attention to the door panel can be further urged as in the case of intermittent illumination.
[0039]
Further, as a form of the present invention, it is applied between a car doorway column (especially inside the back side) and a curtain plate and a car door to illuminate the inner surface of the car door, and the passengers in the car A configuration that encourages attention to the car door is also conceivable.
[0040]
In each of the above embodiments, a cold cathode fluorescent lamp is used as a light source, but an LED (light emitting diode) or an organic EL (electroluminescence) can be used instead of the cold cathode fluorescent lamp. In this case, for example, a plurality of white LEDs and organic EL elements are assembled into a holder having an appropriate shape to form a unit such as a rod, ring, or two-dimensional plane, and the unit is arranged outside the three-sided frame. Set up. In addition, it is also possible to configure in a rod shape, a ring shape, a two-dimensional plane shape, or the like using one element such as an LED or an organic EL.
[0041]
Outside the three-way frame, when only LEDs are disposed as a light source, only when organic EL is disposed, or when an appropriate number of LEDs and organic EL are combined It may be.
[0042]
In addition to white LED and organic EL, other colors can be used according to the surrounding environment, light intensity, usage time zone, season of use, etc. It is also possible to mix EL. Furthermore, it is also possible to dispose a cold cathode fluorescent lamp as a light source on the outside of the three-way frame in combination with the LED and the organic EL.
[0043]
Needless to say, as a means for causing the LED or the organic EL to emit light, a conventionally used drive control device is used.
[0044]
【The invention's effect】
As described above, according to the present invention, when the car arrives at the elevator hall and the door panel of the hall opens, the elevator user can be alerted to the door panel prior to the opening, and thus the door panel opens. Occurrence of troubles can be prevented and the operation efficiency of the elevator can be improved.
