Disclosure of Invention

Technical problem to be solved by the invention

However, in the escalator in the ascending operation, there is a possibility that a user who has entered the lower platform 3 loses balance and falls in the vicinity of the lower R portion, which is changed from the horizontal direction to the inclined direction, and in the event that the user falls in the vicinity of the lower R portion, the falling user may fall in the vicinity of the lower R portion of the escalator in the ascending operation, and the user may be immobilized from the vicinity of the lower R portion and continuously fall, thereby causing stagnation of the user.

However, although patent document 1 describes that the detection control means can detect the falling, staying, or approaching of the user near the entrance of the escalator, it does not mention the judgment as to whether the user is moving in a general manner or whether the user is standing by falling, for the user who detects the falling near the lower R portion of the step on the lower landing deck side where the horizontal direction of the escalator is changed to the inclined direction.

The present invention has been made in view of the above-described circumstances, and an object thereof is to improve safety by determining whether a user is moving or standing by a fall even if the user should fall in the vicinity of the lower R portion of a lower landing stage side step of an escalator or the like, the lower landing stage side step being shifted from a horizontal direction to an inclined direction, and the like.

Technical scheme for solving technical problem

To achieve the above object, the passenger conveyor of the present invention at least includes: a plurality of steps which are connected endlessly and move circularly; a balustrade structural member disposed along a moving direction of the steps and across an upper landing platform and a lower landing platform on which a user rides and lowers the steps; and an endless moving handrail guided by the balustrade structural member to move in synchronization with the steps, wherein the steps on the lower platform side serve as a lower R portion that changes from a horizontal direction to an inclined direction during movement, and wherein a sensor is provided on the balustrade structural member near the lower R portion, and the sensor detects the behavior of the user to determine whether the user is moving in the lower R portion in general or standing by falling.

Effects of the invention

According to the present invention, even if a user falls in the vicinity of the lower R portion of a step that changes from a horizontal direction to an inclined direction of an escalator or the like, it is possible to determine whether the user is moving or standing due to the fall, thereby improving safety.

Detailed Description

The passenger conveyor according to the present invention will be described below based on the illustrated embodiment. In the drawings, the same components are denoted by the same reference numerals, and the description thereof may be omitted when the description is repeated.

[ example 1]

Fig. 1 shows a lower part of an escalator as an embodiment 1 of a passenger conveyor of the present invention, and fig. 2 shows a structure including a control device of the escalator.

As shown in the figure, the escalator 1 is roughly composed of an upper landing stage 2 and a lower landing stage 3 on which passengers get on and off, a frame 4 supported so as to straddle the upper landing stage 2 and the lower landing stage 3, a plurality of steps 5 having steps on the upper surfaces thereof and being endlessly connected and circularly moved, balustrades 6 provided vertically on both sides in the moving direction of the steps 5, and a moving handrail 7 guided by the peripheries of the balustrades 6 and moved.

The plurality of steps 5 are connected endlessly to the step chain 9, and are guided by a guide rail (not shown) provided in the frame 4 to move cyclically. The step chain 9 is wound over a drive sprocket 10 that is pivotally supported on one side in the longitudinal direction of the frame 4 and a driven sprocket 11 that is pivotally supported on the other side in the longitudinal direction of the frame 4. The drive sprocket 10 is driven by a drive device 12 provided in the vicinity thereof, and the moving handrail 7 is also driven in synchronization with the steps 5 by the power of the drive device 12.

The balustrade 6 is constituted by a balustrade panel 13 provided upright on both sides of the steps 5 in the moving direction, a skirt board 14 that partitions the balustrade panel 13 and the steps 5, an inner deck cover 15 that covers the top of the skirt board 14, an outer deck cover 16 that covers the outside of the base of the balustrade panel 13, and an end cover 17 that covers the end portions of the skirt board 14, the inner deck cover 15, and the outer deck cover 16 and has an entrance through which the moving handrail 7 enters and exits.

In the escalator 1 configured as described above, generally, the steps 5 on the lower platform 3 side become the lower R portion 18 that changes from the horizontal direction to the inclined direction during movement (during the ascending operation), and there is a possibility that the user 19 riding in from the lower platform 3 loses balance and falls in the vicinity of the lower R portion 18 that changes from the horizontal direction to the inclined direction, and in the event that the user 19 falls in the vicinity of the lower R portion 18, the falling user 19 may fall in the vicinity of the lower R portion 18 of the escalator 1 that continues the ascending operation, and the user 19 may be immobilized and continuously falls from the vicinity of the lower R portion 18, and stagnate.

Therefore, in the present embodiment, the 1 st sensor (for example, a laser scanning type distance sensor) 20 and the 2 nd sensor (for example, a laser scanning type distance sensor) 21 are provided in the balustrade structure member near the lower R portion 18, and the behavior of the user 19 is detected by the 1 st sensor 20 and the 2 nd sensor 21, and it is determined whether the user 19 is moving in a general direction of the lower R portion 18 or standing by falling.

That is, the 1 st sensor 20 is provided on the balustrade panel 13 constituting the balustrade structural member near the lower R portion 18, the 2 nd sensor 21 is provided at a predetermined interval from the 1 st sensor 20 in the ascending direction of the steps 5, and it is determined whether the user 19 is moving or standing by the fall based on the difference between the information detected by the 1 st sensor 20 and the information detected by the 2 nd sensor 21 after a predetermined time.

Specifically, the 1 st sensor 20 detects whether the general user 19 is moving or the user 19 is standing by falling, the 2 nd sensor 21 detects whether the standing of the user 19 by falling continues, and when the 2 nd sensor 21 detects that the standing of the user 19 by falling continues, an alarm for notifying an abnormal situation (for example, the alarm is the user 19 who has fallen and therefore requests the escalator 1 to stop) is given or the escalator 1 is stopped.

The distance between the 1 st sensor 20 and the 2 nd sensor 21 provided at a predetermined interval in the ascending direction of the step 5 is set to a distance outside the range in which the 1 st sensor 20 can detect the user 19.

The escalator 1 of the present embodiment includes a control device 22, and the control device 22 inputs the information detected by the above-described 1 st sensor 20 and the information detected by the 2 nd sensor 21 after a predetermined time, and the control device 22 determines whether the user 19 is moving or standing by the fall from the difference between the information detected by the 1 st sensor 20 and the information detected by the 2 nd sensor 21 after the predetermined time.

Specifically, the control device 22 is configured by: an acquisition unit 22A that acquires information detected by the 1 st sensor 20 and information detected by the 2 nd sensor 21 after a predetermined time; a signal processing unit 22B that detects whether the general user 19 is moving or whether the user 19 is standing due to a fall or standing on the basis of the signal from the acquisition unit 22A; and a command unit 22C for outputting a warning command to a warning device (e.g., a speaker 23) or outputting a stop command to the drive device 12 for driving the escalator 1, based on a detection signal from the signal processing unit 22B that the user 19 has stopped due to falling. The alarm command output from the command unit 22C to the speaker 23 is preferably performed via the voice synthesizer 24.

With the configuration of this embodiment, even if the user 19 falls in the vicinity of the lower R portion 18 of the steps 5 on the lower landing stage 3 side of the escalator 1, which is shifted from the horizontal direction to the inclined direction, it is possible to determine whether the user 19 is moving or standing still due to the fall, and the safety of the escalator 1 can be improved.

In the above embodiment, the description has been given of the escalator, but the present invention can be applied to any passenger conveyor in which a lower portion R portion whose step is changed from the horizontal direction to the inclined direction is formed.

The present invention is not limited to the above-described embodiments, and various modifications are also included. For example, the above-described embodiments are described in detail for easy understanding of the present invention, but the present invention is not necessarily limited to all of the configurations described. Further, a part of the structure of one embodiment may be replaced with the structure of another embodiment, and the structure of another embodiment may be added to the structure of one embodiment. Further, a part of the configuration of each embodiment may be added, deleted, or replaced with another configuration.
