FIG. 2 is an enlarged view of a main part when viewed from the AA direction of FIG. FIG. 3 is an enlarged view of a portion B in FIG. FIG. 4 is a block diagram of a safety device for passenger conveyors according to Embodiment 1 of the present invention.

  In FIG. 1, 1 and 2 are the upper boarding gate and the lower boarding gate of a passenger conveyor, respectively. Between these entrances 1 and 2, the step 3 circulates. A balustrade 4 is arranged on both sides of the step 3. These balustrades 4 are provided with moving handrails 5. These handrails 5 circulate in synchronization with the steps 3.

  In addition, a building wall surface 6 is disposed outside the both balustrades 4 in the vicinity of the upper entrance 1. Each of these building wall surfaces 6 is provided with a first position detection device 7 and a second position detection device (not shown).

  The first position detection device 7 has a first detection area 8a. The first detection area 8 a is provided in the longitudinal direction of the passenger conveyor inclined portion along one outer side of the balustrade 4. And the first position detection device 7 always detects the position in the longitudinal direction of the passenger conveyor of the user 9 that has entered the first detection area 8a and the luggage of the user 9 (hereinafter referred to as an object). It has a function of emitting a detection beam downward.

  The second position detection device has a second detection area (not shown in FIG. 1). The second detection area is provided in the longitudinal direction of the passenger conveyor inclined portion along the other outer side of the balustrade 4. And a 2nd position detection apparatus has a function which always inject | emits a detection beam below so that the position of the passenger conveyor longitudinal direction of the object which penetrate | invaded in the 2nd detection area may be detected.

  A plurality of first alarm generation devices 10a and a plurality of second alarm generation devices (not shown in FIG. 1) are provided below the forward rails 5 on the balustrades 4 respectively. More specifically, the first alarm generation device 10a is provided on one side of the balustrade 4 with an arbitrary interval P (for example, 1 m interval) in the longitudinal direction of the passenger conveyor inclined portion. The second alarm generation device is provided on the other side of the balustrade 4 with an arbitrary interval P in the longitudinal direction of the passenger conveyor inclined portion. These alarm generation devices 10a and the like have a function of generating an alarm. The first position detection device 7, the second position detection device, the first alarm generation device 10a, and the second alarm generation device are connected to a control circuit (not shown in FIG. 1).

  When the first position detection device 7 detects the position of the object in the longitudinal direction of the passenger conveyor, the control circuit sets the first alarm generation device 10a near the detection position of the object among the plurality of first alarm generation devices 10a. It has a function to select and generate an alarm. The control circuit selects a second alarm generation device in the vicinity of the object detection position from the plurality of second alarm generation devices when the second position detection device detects the position of the object in the longitudinal direction of the passenger conveyor. And has a function of generating an alarm. That is, the control circuit functions as control means for controlling the entire safety device for the passenger conveyor.

  FIG. 1 shows a case where the head of the user 9 has entered the first detection area 8a. In this case, the first position detection device 7 detects that the object is at a position separated by a distance L below the longitudinally inclined portion. Then, the control circuit selects the first alarm generation device 10a near the position and generates an alarm.

Next, the object detection method by the first position detection device 7 will be described in more detail with reference to FIG.
FIG. 2 shows both balustrades 4, both detection areas 8a and 8b, and both alarm generation devices 10a and 10b. As shown in FIG. 2, the user 9 gets on the handrail 5 on the one side of the balustrade 4 and moves on. As a result, the head of the user 9 has entered the first detection area 8a. In this case, the first position detection device 7 performs the same operation as the camera autofocus.

  In an autofocus camera, focusing is started when the shutter is half-pressed. Then, based on the measurement distance when the subject is focused, the lens is moved so that the subject is in focus. Here, the measurement distance is detected based on the time until the object is irradiated with infrared rays, ultrasonic waves, etc. and the reflected wave returns, and the irradiation angle. The 1st position detection apparatus 7 measures the distance of an object similarly to this operation | movement, and detects the position of a passenger conveyor longitudinal direction. Similarly, the second position detecting device also detects the position of the object entering the second detection area 8b in the longitudinal direction of the passenger conveyor.

Next, the principal part of the 2nd alarm generation device 10b is demonstrated using FIG.
FIG. 3 shows the other upper part of the balustrade 4. In FIG. 3, 11 is a guardrail. The guard rail 11 is provided on the other upper part of the balustrade 4. The guard rail 11 has an opening facing upward. The handrail guide 12 is attached so as to close the opening from above. On the upper part of the handrail guide 12, a collar portion is provided. This collar part protrudes from the guardrail 11 both sides. Then, both end portions of the moving handrail 5 are engaged with the collar portion. By this engagement, the moving handrail 5 is guided to the handrail guide 12.

  In such a configuration, a space is formed inside the guard rail 11. In this space, a vibration applying device (not shown in FIG. 3) is provided. This vibration applying device is a main part of the second alarm generating device 10b. More specifically, the vibration applying device has a function of vibrating the handrail guide 12 when the drive power is turned on. Then, the handrail guide 12 transmits such vibration to the forward path side handrail 5.

Next, the configuration and operation of the entire safety device will be described in more detail with reference to FIG. In FIG. 4, for simplification, the second position detection device and the second alarm generation device 10 b are omitted.
The safety device shown in FIG. 4 includes a first position detection device 7, a driving direction information detection means 13, a driving speed information detection means 14, a first alarm generation device 10 a, and a control circuit 15.

  The first position detection device 7 includes an intrusion detection means 7a and a position detection means 7b. The intrusion detection means 7a has a function of detecting an object that enters the first detection area 8a. The position detection means 7b has a function of detecting the position of the object detected by the intrusion detection means 7a in the longitudinal direction of the passenger conveyor.

  The driving direction information detection means 13 has a function of detecting the driving direction of the passenger conveyor. More specifically, the driving direction information detection means 13 has a function of determining whether the passenger conveyor is driven in the upward direction or the downward direction. The driving speed information detecting means 14 has a function of detecting the driving speed of the passenger conveyor. More specifically, the driving speed information detecting unit 14 has a function of detecting the speed of the circular movement of the step 3 and the moving handrail 5.

  The first alarm generation device 10 a includes a vibration applying device 16, a sound announcement generation unit 17, and a buzzer sound generation unit 18. The vibration applying device 16 is the same as that in the second alarm generating device 10b. In other words, the vibration applying device 16 has a function of causing the handrail guide 12 to vibrate, and causing the handrail guide 12 to transmit the vibration to the forward moving handrail 5. The voice announcement generating means 17 has a function of generating a voice announcement that notifies danger. The buzzer sound generating means 18 has a function of generating a general buzzer sound. The first alarm generating device 10a having such a configuration has a function of selecting and operating at least one of the vibration applying device 16, the sound announcement generating unit 17, and the buzzer sound generating unit 18 as an alarm.

  The control circuit 15 receives an object detection signal from the intrusion detection means 7a, and receives position information of the object in the longitudinal direction of the passenger conveyor from the position detection means 7b. The control circuit 15 receives the driving direction information of the passenger conveyor from the driving direction information detection means 13 and the driving speed information of the passenger conveyor from the driving speed information detection means 14.

  Furthermore, when there is a change in the position information of the object, the control circuit 15 determines that the object has protruded from the passenger conveyor center to one outside of the balustrade 4. When the control circuit 15 determines that the object is protruding, the control circuit 15 selects the first alarm generation device 10a closest to the object detection position and generates an alarm. Thereafter, the control circuit 15 switches the first alarm generation device 10a that generates an alarm by following the operation direction and operation speed of the passenger conveyor.

  Note that the control circuit 15 can be set to perform other operations besides the above. For example, when the control circuit 15 determines that an object is protruding, the first alarm generation device 10a closest to the detection position of the object and a plurality of (for example, two) first alarm generation devices on the passenger conveyor driving direction side. 10a can be selected and set to generate an alarm. Furthermore, the control circuit 15 can also be set to switch the first alarm generation device 10a that generates an alarm by following the change in the longitudinal direction of the passenger conveyor of the object detected by the first position detection device 7.

  According to the first embodiment described above, for example, when the position detection device 7 or the like detects the position of the object in the longitudinal direction of the passenger conveyor, among the plurality of alarm generation devices 10a and the like, An alarm can be generated by selecting the alarm generator 10a or the like. For this reason, the user 9 in the vicinity of the object detection position can be alerted so as to be in a good usage state. On the other hand, the alarm generation device 10a and the like other than the vicinity of the object detection position do not generate an alarm. For this reason, the user 9 who is not near the detection position of the object is not alerted. That is, the user 9 is not made uncomfortable.

  When the first position detection device 7 detects an object, the first alarm generation device 10a generates an alarm. On the other hand, when the second position detection device detects an object, the second alarm generation device 10b generates an alarm. For this reason, an alarm can be generated only on the balustrade 4 side where the object protrudes. Therefore, only the user 9 on the object detection position side can be cautioned more reliably.

  Further, if the setting of the alarm generation device 10a and the like is set so that only the vibration applying device 16 operates, the alarm is only the vibration of the forward path handrail 5. For this reason, the alarm does not spread around. Therefore, only the user 9 near the object detection position can be cautioned more reliably.

  In addition, the vibration applying device 16 is provided inside the guard rail 11 and can vibrate the moving handrail 5 by applying vibration to the handrail guide 12. For this reason, the vibration applying device 16 does not require a special balustrade 4. Therefore, an inexpensive safety device is realized.

  In addition, the safety device can select not only the alarm generation device 10a closest to the detection position of the object but also a plurality of alarm generation devices 10a on the driving direction side of the passenger conveyor to generate an alarm. For this reason, even if the user 9 who went out to the outside of the balustrade 4 passes the position by driving the passenger conveyor, the user 9 can be surely alerted.

  Furthermore, the safety device can switch the alarm generation device 10a or the like that generates an alarm by following the operation speed of the passenger conveyor detected by the operation speed information detection means 14 or the like. For this reason, it is possible to operate a more appropriate alarm generation device 10a and the like following the movement of the user 9 who has entered the outside of the balustrade 4.

  In addition, the safety device can also switch the alarm generation device 10a or the like that generates an alarm by following the change in the longitudinal direction of the passenger conveyor of the object detected by the position detection device 7 or the like. For this reason, the configuration of the driving direction information detecting means 13 and the driving speed information detecting means 14 is not required, and the safety device can be simplified.

  The position detection device 7 or the like may be provided on the lower entrance 2 side as long as it has the above-described function. And the 1st position detection apparatus 7 may be provided not on the building wall surface 6 but on a passenger conveyor. Needless to say, the safety device of the present invention is also effective for moving walkways.

It is a longitudinal cross-sectional view of the whole passenger conveyor in which the safety device in Embodiment 1 of this invention is utilized. It is a principal part enlarged view seen from the AA direction of FIG. It is the B section enlarged view of FIG. It is a block diagram of the safety device of a passenger conveyor in Embodiment 1 of this invention.
