Description

Display device

The present invention relates to a display device for displaying identification information on the driving direction of a passenger conveyor.

Generally, the operating direction of a passenger conveyor such as a moving sidewalk or an escalator can be visually determined even from a certain distance from the movement of passengers on a tread, a handrail, and a tread. When there are no passengers, the driving direction of the passenger conveyor cannot be determined based on the movement of the passenger, but can be visually determined even from a certain distance from the movement of the tread and the handrail.

を Consider a case where the passenger conveyor is an escalator and the passenger gets on from the upper floor to the lower floor. In this case, since the user who is about to get on the escalator cannot visually recognize the movement of the tread, it is necessary to determine the driving direction of the escalator by visually checking 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, there is a case where a passenger conveyor is provided with a display function, and a configuration with an optional function of clearly indicating the driving direction using a light emitting diode or the like is adopted. For example, as such a display function, a case where an arrow is displayed at the entrance and an entry prohibition mark is displayed at the exit can be exemplified.

In addition, in the case of performing an automatic operation in which the passenger conveyor is stopped and there is no passenger, the passenger who intends to get on the passenger conveyor in the future, when the passenger conveyor is on standby, the movement of the treads or the handrails. It is not possible to visually determine the driving direction. For this reason, it is necessary to provide a display function that allows the user to identify the driving direction even when 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 seal, or the like.

において In a passenger conveyor that performs automatic driving, a sensor for detecting a passenger may be built in a post or may be built in a passenger conveyor body. In a configuration in which a sensor is incorporated in the post, visibility of the display is ensured by providing the post with a display for identifying the driving direction. However, such a configuration is subject to restrictions on the architectural layout. For this reason, even when performing automatic driving, the display unit cannot always be installed on the post.

Therefore, in the case where there is a restriction on the architectural layout, a configuration in which a sensor is incorporated in the passenger conveyor body and a display unit is provided in the passenger conveyor body is applied. Further, when the automatic driving is not performed, it is necessary to basically provide a display unit on the passenger conveyor body.

However, in the case where the display unit is provided on the passenger conveyor body, the size of the display unit or the installation position is limited, and the visibility is actually poor.

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

従来 The conventional device according to Patent Document 1 is a device in which a screen is installed on a ceiling and images are projected on a screen from a projector arranged on the side of the passenger conveyor to display information.

JP 2016-74535 A

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

The present invention has been made in order to solve such a problem, and a display capable of improving visibility when providing identification information on a driving direction of a passenger conveyor to a user of the passenger conveyor. It is intended to provide a device.

In order to achieve the above object, a display device according to the present invention is installed at a lower portion of a floor plate portion installed at an entrance of a passenger conveyor, and transmits a light to a passenger through a light transmitting portion provided on the floor plate portion for transmitting light. The system includes a projector that projects identification information on the driving direction of the passenger conveyor onto a handrail of the conveyor, and a display control device that controls projection of the identification information by the projector and displays the identification information.

According to the present invention, by employing the above-described configuration, it becomes possible to improve the visibility when providing identification information on the driving direction of the passenger conveyor to the user of the passenger conveyor.

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

Embodiment 1 FIG.
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 Embodiment 1 of the present invention is applied.

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

フレーム 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. The 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 provided so as to connect the other end of the frame F and the upper floor UF. The floor plate section 10 relating to the lower floor LF and the upper floor UF is formed so as to have a slope that is gently inclined and comes into contact with the floor.

{Circle around (2)} In the frame F of the escalator 100, between the floor plates 10 related to the lower floor LF and the upper floor UF, the tread 2 connected endlessly is provided. The tread 2 is circulated 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 provided vertically on the frame F along the traveling direction of the tread plate 2. The balustrade 3 is provided with a handrail 4 that moves at the same speed in the same direction as the traveling direction of the tread 2. The lower inside of the balustrade 3 is covered with an inner deck, and the lower outside of the balustrade 3 is covered with an outer deck.

FIG. 2 is an external perspective view showing a schematic configuration of the escalator 100 on the entrance side or the exit side, partially cut away. However, in FIG. 2, the driving direction of the escalator 100 is the entrance side when going up from the lower floor LF to the upper floor UF, and when going down from the upper floor UF to the lower floor LF. Both the exit side and the exit side are shown.

れば Referring to FIG. 2, in the escalator 100, a light transmitting portion 1 that transmits light is provided on a floor plate portion 10 installed on a floor surface on the entrance side or on the exit side. In addition, a projector 5 that projects identification information on the driving direction to the handrails 4 on both sides through the light transmitting unit 1 and displays the identification information is provided below the floor panel unit 10.

Note that FIG. 2 illustrates a case in which the identification information is displayed on each of the handrails 4 on both sides using two projectors 5. A configuration in which identification information is displayed on the handrail 4 is also possible. In addition, when two projectors 5 are used, it is more practical if the translucent section 1 is separately provided in the front direction of the handrails 4 on both sides of the floor panel section 10.

乗 A passenger sensor 6 is installed at an exit point where the handrail 4 exits the frame F or at an entrance point where the handrail 4 enters the frame F. The passenger sensor 6 is a detection sensor that detects the presence or absence of a passenger approaching the tread 2.

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

参照 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. Note that the passenger sensor 6 is not an essential component. 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 state information for identifying whether the escalator 100 is in the operating state or the stopped state. Has become.

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

Each projector 5 projects identification information on the driving direction to each display location. Each projector 5 is provided with a light source for displaying identification information. These light sources may be installed off the front of 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.

位置 In accordance with this, the position and configuration of the light transmitting unit 1 may be changed. 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 the passenger to step on the scratches and dirt, and the passenger sensor 6 detects the light. Difficult to interfere with the range. The description of the setting arrangement of the projector 5 will be described later in detail. The display control device 7 can control the projection of the identification information by each projector 5 in accordance with the moving direction of the handrail 4, and can display the identification information so as to slide.

(4) A total of four passenger sensors 6 are installed at entrances to and exits from the frame F relating to the handrails 4 on both sides. However, the number of units to be installed is not limited to this, and for example, a configuration in which one unit is installed for each of the upper floor and the lower floor may be employed. The passenger sensor 6 optically detects the presence or absence of a passenger 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.

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

A total of two display control devices 7 are installed on the upper floor and the lower floor of the escalator 100, one at a time below 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. When controlling the display of the identification information by the projector 5, the display control device 7 can also use the detection result of the presence or absence of the passenger from the passenger sensor 6.

More specifically, if the display control device 7 determines that the identification information cannot be displayed on the handrail 4 due to the presence of a passenger based on the detection result of the passenger sensor 6, the display control device 7 displays the information by the projector 5. Is controlled to stop. As a result, the passenger cannot visually recognize the identification information displayed on the handrail 4. However, since this passenger is near the entrance, the movement of the tread 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 located far from the doorway cannot see 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 the passenger near the entrance, even when the identification information cannot be visually recognized, the driving direction of the escalator 100 is referred to the movement of the passenger. Can be determined.

If the controller 200 that controls the operation of the escalator 100 has an automatic driving function, a sensor having the same function as the passenger sensor 6 is provided in the escalator 100 as standard. Here, the automatic driving function is to make the escalator 100 stand by in a low-speed driving state or a stopped state when there are no passengers, and to resume normal driving when the escalator 100 detects a user who is going to ride in the standby state. It is.

In the escalator 100 having such an automatic driving 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, when no display is required, the projection by the projector 5 can be stopped, and power consumption can be suppressed to save energy. On the other hand, when the state information is in the standby state, the identification information on the driving direction of the passenger conveyor can be provided to the user of the passenger conveyor by causing the projector 5 to display the identification information.

FIG. 5 is a schematic diagram showing an example of an up mark indicating the driving direction at the time of the up operation, which is projected onto the curved portion of the lower handrail 4 by the projector 5. FIG. 6 is a schematic diagram showing another example of the up mark indicating the driving direction at the time of the up operation, which is projected onto the curved portion of the lower handrail 4 by the projector 5. These examples show a case where an up mark indicating the driving direction at the time of up operation is adopted as the identification information.

Referring to FIG. 5, one upward arrow is provided from a projector 5 having a light source provided below a floor plate portion 10 to a curved portion of a lower handrail 4 as shown in FIG. 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 determining the driving direction and the entrance of the escalator 100. be able to.

上り 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. For this reason, the visibility when a distant user looks at the driving direction of the escalator 100 can be improved.

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

Referring to FIG. 7, one stop mark is provided for the curved portion of the lower handrail 4 as shown in FIG. 2 through the light transmitting portion 1 from the projector 5 provided with the light source below the floor plate portion 10. 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 determining the driving direction and the exit of the escalator 100. Can be.

下り The down mark shown in FIG. 8 illustrates four downward hat marks. In this case, similar to the case described with reference to FIG. 6, it is possible to improve the visibility of a distant user when viewing the driving direction of the escalator 100. The display service of the driving direction of the escalator 100 described with reference to FIGS. 5 to 8 is intended for a distant user who is going to get on the escalator 100 from now on, not a passenger actually using the escalator 100. You can consider it.

FIG. 9 is a cross-sectional view of the handrail 4 for explaining how the upward mark of FIG. 6 is slid and projected by the projector 5 and partially displayed on the end of the curved portion of the left handrail 4. FIG. 10 is a cross-sectional view of the handrail 4 for explaining how the upward mark of FIG. 6 is slid and projected by the projector 5 and partially displayed on the end of the curved portion of the right handrail 4. 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.

れば Referring to FIG. 9, here, an example is shown in which the light source of the projector 5 installed at the lower part of the floor panel portion 10 is installed at a position deviated from the front direction of the left handrail 4. Referring to FIG. 10, here, a state in which the light source of the projector 5 installed at a lower portion of the floor panel portion 10 is installed at a position deviated from the front direction of the right handrail 4 is illustrated. 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 up mark indicating the driving direction is projected on the left area E of the left handrail 4 by the light source of the projector 5 as shown in FIG. For the right handrail 4, an up mark is projected on the right area E of the right handrail 4 so as to be 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 onto an area including the left area E, so that the display can be viewed from directions other than the front. The driving direction can be made visible. For the handrail 4 on the right side, four upward hat marks may be slid and projected on an 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. Regarding the end of the curved portion of the right handrail 4, the projection is left-right symmetric. Thus, even from a distance other than the front direction, the user can visually recognize the identification information partially displayed in the area E, and can determine that the driving direction of the escalator 100 is up.

Thus, according to the display device of the first embodiment, it is possible to improve the visibility of providing the escalator passenger with the identification information on the driving direction. In addition, it is possible to realize a display device that can determine the driving direction over a wide range at low cost without requiring a special configuration.
