[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided on a passenger conveyor such as an escalator, for example, in which a passenger board can be moved to prevent a passenger's foot or the like from being caught between a passenger board and a step. It relates to the entrance of a passenger conveyor.

2. Description of the Related Art FIG. 7 is a plan view showing an entrance and exit of a conventional escalator disclosed in Japanese Utility Model Publication No. 55-11898, FIG. 8 is a side view of FIG. 7, and FIG. 9 is a line IX-IX of FIG. FIG. In the figure, 1 is a frame of an escalator, 2 is a step, and 3 is a pair of rails fixed parallel to the frame 1, and only one side is shown in the figure.

Reference numeral 4 denotes a first loading / unloading plate adjacent to the step 2, and rotatable rollers 5 are provided on both sides of the first loading / unloading plate 4 so that the first loading / unloading plate 4 is provided.
Is reciprocable along the rail 3. 6 is the first
Attached to the end of the step 2 side of the board 4
Is a comb-like member that blocks the space between the boarding board 4 and the step 2.

[0004] Reference numeral 7 denotes a dock protruding from the side of the first board 4, and reference numeral 8 denotes a lever rotatably attached to the rail 3. One end of the lever 8 engages with the dock 7. I have. Reference numeral 9 denotes a coil spring for urging the first board 4 toward the step 2 through the lever 8 and the dock 7, reference numeral 10 denotes a screw for adjusting the spring force of the coil spring 9, and reference numeral 11 denotes a screw 10 for adjusting the spring force.
Is a stopper which is provided at the end of the rail 3 and is in contact with the roller 5.
The movement of the first getting on / off plate 4 to the step 2 side is restricted.

[0005] Reference numeral 13 denotes a movement detection dock projecting from the side of the first boarding / exiting board 4, and reference numeral 14 denotes a limit switch having a detection lever 15 in contact with the movement detection dock 13. When the detection lever 15 is operated by the movement detection dock 13, the operation of the escalator is stopped. 16 is a guide rail for guiding step 2, 17 is a passenger's foot, and 18 is a clearance A with respect to the first board 4
This is a second boarding / alighting board provided at a position.

Next, the operation will be described. Step 2
When the passenger's foot 17 or luggage or the like collides with the comb-shaped member 6 at the entrance / exit without changing onto the first entrance / exit board 4, a large force in the step moving direction acts on the first entrance / exit board 4. By this force, the first boarding / leaving plate 4 moves in the step movement direction against the coil spring 9. When the first board 4 moves, the detection lever 15 is operated by the movement detection dock 13, the limit switch 15 is operated, and the operation of the escalator is stopped. In this manner, the foot 17 and luggage are prevented from being caught between the comb member 6 of the first boarding board 4 and the step 2.

[0007]

At the entrance of the conventional escalator constructed as described above, the first entrance / exit by the gap A between the first entrance / exit plate 4 and the second entrance / exit plate 18 is provided. Although the movement of the board 4 is allowed, the size of the gap A is limited, so that the moving distance of the first board 4 in the step movement direction is limited to the above-described gap dimension. Couldn't be big enough. As a result, the moving distance of Step 2 from the time when the foot 17 or the like collides with the comb-shaped member 6 to the time when the operation of the escalator is stopped is larger.
During that time, it becomes larger than the moving distance of the first boarding / exiting board 4,
There was a problem that there was a risk of damaging the passenger's feet 17 and the like.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and can provide a sufficient moving distance of a boarding board adjacent to a step, thereby improving safety. The purpose is to get a passenger conveyor entrance that can be.

[0009]

The entrance of the passenger conveyor according to the present invention is provided with an inclined portion on a rail for guiding the first entrance / exit board so that the first entrance / exit board can be moved when the first entrance / exit board is moved.
In such a manner that the end of the board gets under the second board.

[0010]

According to the present invention, by sliding the first boarding board below the second boarding board adjacent thereto,
The moving distance of the first boarding / exiting plate is made sufficiently long.

[0011]

【Example】

Embodiment 1 FIG. FIG. 1 is a plan view showing an entrance / exit of an escalator according to an embodiment of the present invention, and FIG. 2 is a side view of FIG. 1, in which the same or corresponding parts as those in FIGS. Is omitted.

In FIG. 1, reference numeral 21 denotes a first rail fixed to the frame 1 for guiding the rollers 5 on the comb-like member 6 side, and reference numeral 22 denotes a second rail fixed to the frame 1 for guiding the rollers 5 on the opposite side. The first and second rails 21 and 22 are provided with first and second inclined portions 21a and 22a, respectively. Thereby, the first boarding / subtracting plate 4 slides below the second boarding / subtracting plate 18 when moving in the step moving direction.

Next, the operation will be described. Passenger feet17
When a large force in the step moving direction acts on the first boarding / discharging plate 4 due to the collision of a load or the like, the first boarding / leaving plate 4 moves in the step moving direction against the coil spring 9. Here, FIG. 3 is a cross-sectional view of the first and second lift boards 4 and 18 taken along the line III-III of FIG. 1, and FIG. 4 is a cross-sectional view showing a state where the first lift board 4 of FIG. It is. As shown in FIG. 4, the first board 4 is guided by the first and second rails 21 and 22,
The user slides under the second board 18 while maintaining the posture.
When the first board 4 moves, the limit switch 15 operates as in the prior art, and the operation of the escalator is stopped.

At the entrance of the escalator, when the first board 4 moves, it moves below the second board 18 without colliding with the second board 18, so that the first board 4 moves. A sufficient distance can be secured. Therefore, the moving distance in step 2 until the operation of the escalator is stopped by the limit switch 15 and the moving distance of the first board 4 can be made the same. It is possible to more reliably prevent the foot 17 or the like from being caught between the two.

Embodiment 2 FIG. In the first embodiment, the first and second rails 21 and 22 are provided below the roller 5. However, for example, as shown in FIGS.
And the fourth rails 23 and 24 may be provided to guide the rollers 5 between the first and second rails 21 and 22 and the third and fourth rails 23 and 24. This allows
The first board 4 is prevented from rising, and the first board 4 can be slid under the second board 18 more reliably.

Further, in each of the above embodiments, the front and rear rollers 5 are guided by different rails, but may be constituted by one and the same rail. Further, the means for detecting the movement of the first boarding / subtracting board 4 and stopping the operation of the escalator is not limited to those of the above embodiments. Furthermore, in each of the above embodiments, the entrance of the escalator is shown, but the present invention can be applied to the entrance of a moving sidewalk.

[0017]

As described above, the entrance / exit of the passenger conveyor according to the present invention is provided with the inclined portion on the rail for guiding the first entrance / exit plate, so that the first entrance / exit plate can be moved when the first entrance / exit plate is moved. Since the end portion of the boarding board is sunk under the adjacent second boarding board, the moving distance of the first boarding board can be sufficiently set, and thereby, the distance between the first boarding board and the step can be increased. Thus, it is possible to more reliably prevent the passengers' feet or the like from being pinched, and to improve safety.
