Abstract

The display device of the passenger conveyor is installed at the lower part of the floor plate portion installed at the entrance / exit of the passenger conveyor, and the passengers are referred to the handrail of the passenger conveyor through the translucent portion provided on the floor plate portion to transmit light. It includes a projector that projects identification information regarding the operating direction of the conveyor, and a display control device that controls the projection of the identification information by the projector and displays the identification information.

Description

The present invention relates to a display device that displays identification information regarding the operating direction of a passenger conveyor.

In general, the driving direction of a passenger conveyor such as a moving walkway or an escalator can be visually determined from the movements of the treads, handrails, and passengers on the treads even from a certain distance. When there are no passengers, the operating direction of the passenger conveyor cannot be determined based on the movements of the passengers, but can be visually determined from the movements of the treads and handrails even from a certain distance.

Consider the case where the passenger conveyor is an escalator and the passengers board from the upper floor to the lower floor. In this case, since the user who is about to board the escalator cannot visually recognize the movement of the tread, it is necessary to visually determine the driving direction of the escalator by visually observing the movement of the handrail. For this reason, it is difficult for the user to visually determine the driving direction of the escalator from a distance only by the movement of the tread plate.

Therefore, as a service for escalator users, a passenger conveyor may be provided with a display function, and a configuration with an optional function for clearly indicating the driving direction using a light emitting diode or the like may be adopted. For example, as such a display function, a case where an arrow is displayed at the entrance and an intrusion prohibition mark is displayed at the exit can be exemplified.

In addition, in the case of automatic operation in which the passenger conveyor is stopped and put on standby when there are no passengers, the user who is about to board the passenger conveyor can move the tread or the handrail while the passenger conveyor is on standby. It is not possible to visually determine the driving direction. Therefore, it is necessary to provide a display function that allows the user to identify the driving direction even while the passenger conveyor is on standby. However, when the driving direction is fixed, the driving direction may be clearly indicated by displaying a signboard, a sticker, or the like.

In a passenger conveyor that performs automatic operation, a sensor for detecting passengers may be built in a post or a passenger conveyor body. In the configuration in which the sensor is built in the post, the visibility of the display unit is ensured by providing the post with a display unit for identifying the driving direction. However, such a configuration is subject to architectural layout restrictions. Therefore, even in the case of automatic operation, it is not always possible to install a display unit on the post.

Therefore, when there are restrictions on the architectural layout, a configuration in which a sensor is built in the passenger conveyor body and a display unit is provided in the passenger conveyor body is applied. Further, when automatic operation is not performed, it is basically necessary to provide a display unit on the passenger conveyor body.

However, when the display unit is provided on the main body of the passenger conveyor, there are restrictions on the size of the display unit or the installation position, and the visibility is poor.

Therefore, in order to solve such a problem, there is a conventional device that displays information on the ceiling of the space where the passenger conveyor is installed by using a projector (see, for example, Patent Document 1).

In the conventional device according to Patent Document 1, a screen is installed on the ceiling, and an image is projected on the screen from a projector arranged on the side of a passenger conveyor to display information.

Japanese Unexamined Patent Publication No. 2016-74535

However, it is assumed that the information displayed on the ceiling screen becomes a blind spot from a distance and cannot be visually recognized. In such a case, the user who is about to board the passenger conveyor may not be able to visually determine the information regarding the driving direction of the passenger conveyor, which is important as a service for the user.

The present invention has been made to solve such a problem, and is a display capable of improving visibility when providing identification information regarding the operating direction of the passenger conveyor to the user of the passenger conveyor. The purpose is to provide the device.

In order to achieve the above object, the display device according to the present invention is installed under the floor plate portion installed at the entrance / exit of the passenger conveyor, and the passenger is passed through the translucent portion provided in the floor plate portion to transmit light. It includes a projector that projects identification information about the operating direction of the passenger conveyor on the handrail of the conveyor, and a display control device that controls the projection of the identification information by the projector and displays the identification information.

According to the present invention, by adopting the above configuration, it becomes possible to improve the visibility when providing the identification information regarding the operating direction of the passenger conveyor to the user of the passenger conveyor.

Hereinafter, the display device of the present invention will be described in detail with reference to the drawings with reference to embodiments.

Embodiment 1.
FIG. 1 is a side view showing a basic configuration of an escalator 100, which is an example of a passenger conveyor to which the display device according to the first embodiment of the present invention is applied.

Referring to FIG. 1, the escalator 100 is installed between the floors of the building, and is installed between the lower floor LF and the upper floor UF in the up or down driving direction as shown by the arrow. By being driven, it carries passengers who are users. Hereinafter, the user will be a passenger. Normally, the escalator 100 is used with the driving direction set to either up or down.

The frame F of the escalator 100 is provided so that both ends in the longitudinal direction extend between the lower floor LF and the upper floor UF. The frame F may be called a truss. A floor plate portion 10 is installed so as to connect one end of the frame F and the lower floor LF. Further, a floor plate portion 10 is installed so as to connect the other end of the frame F and the upper floor UF. The floor plate portion 10 related to the lower floor LF and the upper floor UF is formed so as to have an inclined portion that is gently inclined and is in contact with the floor.

Further, in the frame F of the escalator 100, a tread plate 2 connected in an endless manner is provided between the floor plate portion 10 related to the lower floor LF and the upper floor UF. The tread plate 2 circulates between the lower floor LF and the upper floor UF by a driving device such as a motor. Further, in the escalator 100, the balustrade 3 is vertically provided on the frame F along the traveling direction of the tread plate 2. The balustrade 3 is provided with a handrail 4 that moves in the same direction as the traveling direction of the tread plate 2 at the same speed. The lower inside of the balustrade 3 is covered with an inner deck, and the lower outer side of the balustrade 3 is covered with an outer deck.

FIG. 2 is an external perspective view showing a schematic configuration of the entrance side or the exit side of the escalator 100 with a partial break. However, in FIG. 2, the operating direction of the escalator 100 is the entrance side when going up from the lower floor LF to the upper floor UF, and the case where the escalator 100 is going down from the upper floor UF to the lower floor LF. It is also shown as the exit side.

Referring to FIG. 2, in the escalator 100, the floor plate portion 10 installed on the floor surface on the entrance side or the exit side is provided with a light transmitting portion 1 for transmitting light. Further, below the floor plate portion 10, a projector 5 is installed which projects identification information regarding the driving direction onto the handrails 4 on both sides through the translucent portion 1 and displays the identification information.

Note that FIG. 2 illustrates a case where two projectors 5 are used to display identification information on each of the handrails 4 on both sides, but one projector 5 is used to display identification information on either the left or right side. It is also possible to have the handrail 4 display the identification information. In addition, when two projectors 5 are used, it is more practical if the translucent portion 1 is provided separately in the front direction of the handrails 4 on both sides of the floor plate portion 10.

Passenger sensors 6 are installed at exits where the handrail 4 exits the frame F or at entrances where the handrail 4 enters the frame F. The passenger sensor 6 is a detection sensor that detects the presence or absence of passengers approaching the tread plate 2.

FIG. 3 is a functional block diagram showing a basic configuration of a display device 101 provided in the escalator 100.

Referring to FIG. 3, the display device 101 according to the third embodiment includes a projector 5, a passenger sensor 6, and a display control device 7. The passenger sensor 6 is not an essential configuration. Further, the display control device 7 in the display device 101 is connected to the controller 200 that controls the operation of the escalator 100, and can acquire the state information for identifying whether the escalator 100 is in the operating state or the stopped state. It has become.

A total of four projectors 5, two on the upper floor and two on the lower floor, are installed under the floor plate portion 10 on the entrance / exit side of the escalator 100. As shown in FIG. 2, each of these projectors 5 can project necessary information through the translucent portion 1 with the curved portion of the handrail 4 as a display location.

Each projector 5 projects identification information regarding the driving direction to each display location. Each projector 5 is configured to include a light source for displaying identification information. These light sources may be installed away from the front direction with respect to the handrail 4. In such a case, the identification information projected from each projector 5 can be visually recognized from a direction other than the front direction of the handrail 4.

The position and configuration of the translucent portion 1 may be changed accordingly. For example, as shown in FIG. 4, if the translucent portions 1 are separately provided in the front direction of the handrails 4 on both sides of the floor plate portion 10, it is difficult for passengers to step on them and get scratches or stains, and the passenger sensor 6 detects them. Hard to interfere with the range. The description of the setting arrangement of the projector 5 will be described in detail later. The display control device 7 can control the projection of the identification information by each projector 5 according to the moving direction of the handrail 4, and can display the identification information so as to slide it.

Two passenger sensors 6 are installed at the entrances and exits to the frame F related to the handrails 4 on both sides, for a total of four passenger sensors 6. However, the number of installations is not limited to this, and for example, it is possible to adopt a configuration in which one is installed on each of the upper floor and the lower floor. The passenger sensor 6 optically detects the presence or absence of passengers approaching the tread plate 2. The detection area does not matter. The passenger sensor 6 can be configured as a combination of a light emitting unit and a light receiving unit.

The light emitting unit of the passenger sensor 6 may use a wavelength that does not interfere with the display by the projector 5. The passenger sensor 6 is not limited to this, and may also use electromagnetic waves including infrared rays, sound waves, and the like. When the light emitting part emits electromagnetic waves, sound waves, etc., it is more appropriate to call it a starting part. In that case, it is more appropriate that the light receiving part is called a receiving part. In short, the passenger sensor 6 may have a function as a detection sensor for detecting passengers.

A total of two display control devices 7 are installed on the upper floor and the lower floor of the escalator 100, one at the bottom of the floor plate portion 10. These display control devices 7 control the projection of the identification information by the projector 5 and display the identification information. Further, the display control device 7 can also use the detection result of the presence or absence of passengers from the passenger sensor 6 when controlling the display of the identification information by the projector 5.

Specifically, when the display control device 7 determines that the identification information cannot be displayed on the handrail 4 due to the presence of passengers based on the detection result of the passenger sensor 6, the projector 5 displays the information. Controls to stop. As a result, the passenger cannot visually recognize the identification information displayed on the handrail 4. However, since this passenger is in the vicinity of the entrance / exit, the movement of the tread plate 2 or the handrail 4 of the escalator 100 can be visually recognized, and the driving direction of the escalator 100 can be easily determined.

On the other hand, a user who is far from the entrance / exit cannot visually recognize the identification information because the display of the identification information by the projector 5 is stopped. However, since a distant user can visually recognize the movement of passengers in the vicinity of the entrance / exit, even if the identification information cannot be visually recognized, the driving direction of the escalator 100 is referred to the movement of the passengers. It becomes possible to discriminate.

When the controller 200 that controls the operation of the escalator 100 has an automatic driving function, the escalator 100 is equipped as standard with a sensor having a function equivalent to that of the passenger sensor 6. Here, the automatic driving function is a function that causes the escalator 100 to stand by in a low-speed operation state or a stopped state when there are no passengers, and resumes normal operation when a user who is about to board the escalator 100 is detected in the standby state. Is.

In the escalator 100 having such an automatic operation function, the display control device 7 controls the display of the identification information by the projector 5 according to the state information by acquiring the state information of the escalator 100 from the controller 200. can do. As a result, the projection by the projector 5 can be stopped when the display is unnecessary, and the power consumption can be suppressed to save energy. On the other hand, when the state information is in the standby state, the identification information regarding the operating direction of the passenger conveyor can be provided to the user of the passenger conveyor by displaying the identification information by the projector 5.

FIG. 5 is a schematic view showing an example of an ascending mark indicating an operating direction during ascending operation projected onto the curved portion of the lower handrail 4 by the projector 5. Further, FIG. 6 is a schematic view showing another example of an ascending mark indicating an operating direction during ascending operation projected onto the curved portion of the lower handrail 4 by the projector 5. These examples show a case where an ascending mark indicating an operating direction during ascending operation is adopted as identification information.

Referring to FIG. 5, one upward arrow refers to the curved portion of the lower handrail 4 as shown in FIG. 2 through the translucent portion 1 from the projector 5 provided with the light source below the floor plate portion 10. Is projected. That is, the display control device 7 controls the projector 5 to display one upward arrow on the curved portion of the handrail 4 on both sides as identification information for discriminating the driving direction and the entrance of the escalator 100. be able to.

The up mark shown in FIG. 6 illustrates four upward hat marks. This makes it possible to display the identification display shown in FIG. 6 with a certain size in the front direction at a relatively high position. Therefore, it is possible to improve the visibility when a distant user visually recognizes the driving direction of the escalator 100.

FIG. 7 is a schematic view showing an example of a down mark showing an operation direction during a down operation projected on a curved portion of a lower handrail 4 by a projector 5. Further, FIG. 8 is a schematic view showing another example of the down mark indicating the driving direction during the down operation projected on the curved portion of the lower handrail 4 by the projector 5. These examples show the case where the down mark indicating the driving direction at the time of down driving is adopted as the identification information.

Referring to FIG. 7, one stop mark is formed on the curved portion of the lower handrail 4 as shown in FIG. 2 through the translucent portion 1 from the projector 5 provided with the light source below the floor plate portion 10. Be projected. That is, the display control device 7 controls the projector 5 to display one stop mark on the curved portion of the handrail 4 on both sides as identification information for discriminating the driving direction and the exit of the escalator 100. Can be done.

The down marks shown in FIG. 8 exemplify four downward hat marks. In this case, as in the case described with reference to FIG. 6, it is possible to improve the visibility when a distant user visually recognizes the driving direction of the escalator 100. The driving direction display service of the escalator 100 described with reference to FIGS. 5 to 8 is intended for distant users who are about to board the escalator 100, not for passengers who are actually using the escalator 100. You can consider it.

FIG. 11 is a front view for explaining an area in which the up mark of FIG. 6 is partially displayed on the left handrail 4 by the projector 5. FIG. 12 is a side view for explaining a state in which the up mark of FIG. 6 is partially displayed on the left handrail 4 by the projector 5.

With reference to FIG. 9, here, a state in which the light source of the projector 5 installed at the lower portion of the floor plate portion 10 is installed at a position deviated from the front direction of the handrail 4 on the left side is illustrated. With reference to FIG. 10, here exemplifies a state in which the light source of the projector 5 installed at the lower portion of the floor plate portion 10 is installed at a position deviated from the front direction of the right handrail 4. For example, it is assumed that the installation position of the light source of the projector 5 is outside the front direction of the handrail 4. In such a case, the light source of the projector 5 projects the up mark indicating the driving direction onto the left region E of the left handrail 4 as shown in FIG. The handrail 4 on the right side is also projected onto the region E on the right side of the handrail 4 on the right side so that the up mark is symmetrical.

That is, as shown in FIG. 11, the display control device 7 slides and projects four upward hat marks on the left handrail 4 to the area including the left area E, so that the display control device 7 can also be used from a direction other than the front direction. The driving direction can be made visible. For the handrail 4 on the right side, four upward hat marks may be slidly projected onto the area including the area E on the right side.

FIG. 12 shows the state of the end of the curved portion of the left handrail 4 at that time. The projection of the curved portion of the handrail 4 on the right side is symmetrical. As a result, the user can visually recognize the identification information partially displayed in the area E even from a distance other than the front direction, and can determine that the driving direction of the escalator 100 is up.
