Embodiment 1.
Fig. 1 is a configuration diagram showing one escalator of a pair of escalators provided with an escalator reverse entry prevention device according to embodiment 1. Fig. 2 is a configuration diagram showing the other escalator of the pair of escalators provided with an escalator reverse entry prevention device according to embodiment 1.

The escalator reverse entry prevention device according to the first embodiment is installed on a pair of escalators 1. In FIG. 1, a first escalator 1A, which is one of the pair of escalators 1, is shown. In FIG. 2, a second escalator 1B, which is the other of the pair of escalators 1, is shown. In this example, an escalator will be used as an example of a passenger conveyor.

The first escalator 1A and the second escalator 1B are each provided across the upper floor 2 and the lower floor 3. The first escalator 1A and the second escalator 1B are arranged parallel to each other. Therefore, the upper floor entrance 11 of the first escalator 1A and the upper floor entrance 11 of the second escalator 1B are adjacent to each other, and the lower floor entrance 12 of the first escalator 1A and the lower floor entrance 12 of the second escalator 1B are adjacent to each other.

The steps move in a circular motion along a travel route that includes an outbound side and a return side. On the outbound side, the step moves from the lower floor 3 to the upper floor 2, which is called an upbound motion, and on the outbound side, the step moves from the upper floor 2 to the lower floor 3, which is called a downbound motion. When moving along the outbound side, the step is in a state in which a user can stand on it.

When the first escalator 1A and the second escalator 1B are both in normal operation, the first escalator 1A is in descending operation, and the second escalator 1B is in ascending operation. When the operation of the first escalator 1A is stopped in order to perform maintenance and inspection of the first escalator 1A, the operation of the second escalator 1B remains in ascending operation. On the other hand, when the operation of the second escalator 1B is stopped in order to perform maintenance and inspection of the second escalator 1B, the operation of the first escalator 1A becomes ascending operation. Thus, the operation of the first escalator 1A is switched between descending operation and ascending operation.

In FIG. 1, the first escalator 1A is in upward operation. Therefore, a user who stands on the step at the lower floor entrance 12 of the first escalator 1A moves to the upper floor entrance 11 of the first escalator 1A.

In FIG. 2, the operation of the second escalator 1B is stopped. By stopping the operation of the second escalator 1B, maintenance and inspection of the second escalator 1B is possible. A safety fence 4 is provided at each of the upper floor entrance 11 and the lower floor entrance 12 of the second escalator 1B. By providing the safety fence 4 at each of the upper floor entrance 11 and the lower floor entrance 12 of the second escalator 1B, users are prevented from entering the upper floor entrance 11 and the lower floor entrance 12 of the second escalator 1B.

When viewed from above, reverse entry refers to entry into the entrance/exit of escalator 1 in the opposite direction to the direction of movement of the tread of the moving step on the outward journey. Specifically, reverse entry refers to a user entering the upper entrance/exit 11 of escalator 1 from upper floor 2 when escalator 1 is operating in an upward direction. Also, reverse entry refers to a user entering the lower entrance/exit 12 of escalator 1 from lower floor 3 when escalator 1 is operating in a downward direction.

When the operation of the second escalator 1B is stopped and the operation of the first escalator 1A is in upward operation, there is a possibility that a user may reverse into the upper floor entrance/exit 11 of the first escalator 1A. When a user reverses into the upper floor entrance/exit 11 of the first escalator 1A, the escalator reverse entry prevention device 5 of embodiment 1 detects the user and issues a warning to the reverse-entering user.

Figure 3 is a plan view showing a part of the first escalator 1A in Figure 1 and a part of the escalator reverse entry prevention device 5 provided on the upper floor 2. Figure 4 is a block diagram showing the escalator reverse entry prevention device 5 according to the first embodiment. The escalator reverse entry prevention device 5 according to the first embodiment includes a pressure detection mat 51, a reverse entry determination device 52, and a warning device 53.

The pressure detection mat 51 is provided on the upper surface of the upper floor floor 2 adjacent to the upper floor entrance 11 of the first escalator 1A. A user moves on the pressure detection mat 51. As the user moves on the pressure detection mat 51, the pressure detection mat 51 is stepped on by the user. As the user steps on the pressure detection mat 51, the pressure detection mat 51 detects the pressure acting on the pressure detection mat 51. The detection result of the pressure detection mat 51 is input to the reverse entry determination device 52.

When a user steps on the pressure detection mat 51, the reverse entry determination device 52 uses the detection result of the pressure detection mat 51 to determine whether or not the user has entered the upper floor entrance/exit 11 of the first escalator 1A in the reverse direction.

The warning device 53 has a hook (not shown). The warning device 53 is attached to the safety fence 4 by hanging the hook on the safety fence 4. The warning device 53 issues a warning based on the judgment result of the reverse entry judgment device 52. The warning device 53 has a speaker. The warning device 53 warns a user who is reversing into the upper floor entrance 11 by audio that the user is reversing into the upper floor entrance 11.

Next, we will explain how the reverse entry determination device 52 determines whether a user has entered in the reverse direction. With respect to the direction in which the user moves on the pressure detection mat 51, the forward direction is the same as the direction of movement of the step tread moving on the outward path when viewed from above, and the reverse direction is the opposite direction to the direction of movement of the step tread moving on the outward path.

Figure 5 is a diagram showing the change in pressure detected by the pressure detection mat 51 when a user moves in the forward direction on the pressure detection mat 51 of Figure 3. Figure 6 is a diagram showing the change in pressure detected by the pressure detection mat 51 when a user moves in the reverse direction on the pressure detection mat 51 of Figure 5. In each of Figures 5 and 6, the direction facing the right is the forward direction D1, and the direction facing the left is the reverse direction D2. Figures 5 and 6 show the feet 6 of a user. In Figures 5 and 6, the first escalator 1A is operating in an upward direction. In other words, in Figures 5 and 6, the first escalator 1A is operating in a direction in which the tread of the moving step on the outward path moves closer to the pressure detection mat 51.

The detection area of the pressure detection mat 51 is divided into a first area 511, which is an area on the upper floor entrance 11 side, and a second area 512, which is an area on the opposite side of the upper floor entrance 11, in the depth direction A of the upper floor entrance 11 of the first escalator 1A. In this example, the depth direction A is the depth direction A of the upper floor entrance 11 of the first escalator 1A.

When a user moves forward on the pressure detection mat 51, the user steps on the first area 511 before the second area 512. As shown in FIG. 5, when the first escalator 1A is in an upward operation and the user steps on the first area 511 before the second area 512, the reverse entry determination device 52 determines that the user has not entered the upper floor entrance/exit 11 in reverse.

When a user moves in the reverse direction on the pressure detection mat 51, the user steps on the second area 512 before the first area 511. As shown in FIG. 6, when the first escalator 1A is in an upward operation and the user steps on the second area 512 before the first area 511, the reverse entry determination device 52 determines that the user is entering the upper floor entrance/exit 11 in the reverse direction.

As described above, the escalator reverse entry prevention device 5 according to the first embodiment includes a pressure detection mat 51 and a reverse entry determination device 52. The pressure detection mat 51 is provided on the upper surface of the upper floor 2 adjacent to the upper floor entrance 11 of the first escalator 1A. When a user steps on the pressure detection mat 51, the reverse entry determination device 52 uses the detection result of the pressure detection mat 51 to determine whether or not the user has reversed into the upper floor entrance 11. With this configuration, when a user reversely enters the upper floor entrance 11, it is possible to detect the user's reverse entry into the upper floor entrance 11.

In addition, in the escalator reverse entry prevention device 5 according to embodiment 1, the detection area of the pressure detection mat 51 is divided in the depth direction A into a first area 511, which is an area on the upper floor entrance/exit 11 side, and a second area 512, which is an area on the opposite side of the upper floor entrance/exit 11. When the first escalator 1A is in an upward operation and the second area 512 is stepped on by the user before the first area 511, the reverse entry determination device 52 determines that the user is entering the upper floor entrance/exit 11 in reverse. With this configuration, it is possible to detect, with a simple configuration, that a user is entering the upper floor entrance/exit 11 in reverse.

The reverse entry prevention device 5 of the escalator according to the first embodiment is also equipped with a warning device 53. The warning device 53 warns users who reverse-enter the upper floor entrance 11 based on the determination result of the reverse entry determination device 52. With this configuration, when a user reverses into the upper floor entrance 11, a warning can be issued to the user. As a result, users can be prevented from reversely entering the upper floor entrance 11.

In the escalator reverse entry prevention device 5 according to the first embodiment, the pressure detection mat 51 is provided on the upper surface of the upper floor floor 2 adjacent to the upper floor entrance 11 of the first escalator 1A. A safety fence 4 is provided on the upper floor floor 2 adjacent to the upper floor entrance 11 of the second escalator 1B. The warning device 53 is provided on the safety fence 4. With this configuration, when a user reverses into the upper floor entrance 11 of the first escalator 1A, a warning can be issued more effectively to the user who reverses into the upper floor entrance 11 of the first escalator 1A.

Embodiment 2.
Fig. 7 is a diagram showing a change in pressure detected by the pressure detection mat when a user moves in the forward direction on the pressure detection mat in the escalator reverse entry prevention device according to the second embodiment. Fig. 8 is a diagram showing a change in pressure detected by the pressure detection mat when a user moves in the reverse direction on the pressure detection mat of Fig. 7. In each of Figs. 7 and 8, the direction facing the right side is the forward direction D1, and the direction facing the left side is the reverse direction D2. Figs. 7 and 8 show the feet 6 of the user. In Figs. 7 and 8, the first escalator 1A is operating in an upward direction. In other words, in Figs. 7 and 8, the first escalator 1A is operating in a direction in which the tread of the step moving on the outward path moves closer to the pressure detection mat 51.

The escalator reverse entry prevention device 5 according to the second embodiment differs from the escalator reverse entry prevention device 5 according to the first embodiment in the method by which the reverse entry determination device 52 determines whether or not a user has entered in the reverse direction.

The contact time is the time from when the user's foot 6 starts to step on the pressure detection mat 51 until it leaves the mat. The reverse entry determination device 52 measures the position of the center C of pressure acting on the pressure detection mat 51 by the user's foot 6 during the contact time.

When a user moves forward on the pressure detection mat 51, the center C of pressure acting on the pressure detection mat 51 by the user's foot 6 moves in the depth direction A away from the upper floor entrance 11 during the contact time. As shown in FIG. 7, when the first escalator 1A is in an upward operation and the center C moves in the depth direction A away from the upper floor entrance 11 during the contact time, the reverse entry determination device 52 determines that the user is not entering in the reverse direction.

When a user moves in the reverse direction on the pressure detection mat 51, the center C of pressure acting on the pressure detection mat 51 by the user's foot 6 moves in the depth direction A toward the upper floor entrance/exit 11 during the contact time. As shown in FIG. 8, when the first escalator 1A is in an upward operation and the center C moves in the depth direction A toward the upper floor entrance/exit 11 during the contact time, the reverse entry determination device 52 determines that the user is entering in the reverse direction. The other configurations are the same as those of embodiment 1.

As described above, in the escalator reverse entry prevention device 5 according to the second embodiment, the reverse entry determination device 52 measures the position of the center C of pressure acting on the pressure detection mat 51 by the user's foot 6 during the contact time. When the first escalator 1A is operating in an upward direction, and the center C moves closer to the upper floor entrance/exit 11 in the depth direction A during the contact time, the reverse entry determination device 52 determines that the user is entering the upper floor entrance/exit 11 in reverse if the first escalator 1A is operating in an upward direction. With this configuration, it is possible to detect, with a simple configuration, that a user is entering the upper floor entrance/exit 11 in reverse.

In each embodiment, an escalator has been described as an example of a passenger conveyor, but it is not limited to an escalator and may be, for example, a moving walkway. When the part of the moving walkway that carries users is a belt, the belt moves in a circular motion along a moving route that includes an outward and return side. When viewed from above, entry into the boarding and alighting entrance of the moving walkway in the opposite direction to the moving direction of the tread of the belt moving on the outward side is called reverse entry.

In each embodiment, a pressure detection mat 51 is provided on the upper floor floor 2 of the escalator 1, and the escalator reverse entry prevention device 5 is configured to detect reverse entry of a user into the upper floor entrance 11 when the user reverses into the upper floor entrance 11. However, the escalator reverse entry prevention device 5 may be configured to detect reverse entry of a user into the lower floor entrance 12 when the user reverses into the lower floor entrance 12 when the user reverses into the lower floor entrance 12. In this case, the escalator 1 performs a descending operation.

In addition, in each embodiment, a configuration has been described in which the warning device 53 is provided on the safety fence 4. However, the warning device 53 may also be provided on the pressure detection mat 51. This makes it possible to warn users who reverse into the upper floor entrance 11 even if the safety fence 4 is not provided on the upper floor floor 2. In this case, the warning device 53 may have a display device that displays a no entry mark to warn the user. This makes it possible for the warning device 53 to warn users who reverse into the upper floor entrance 11 that they are reversely reversing into the upper floor entrance 11, by displaying it on the display device.
