It shows about an escalator in which an inclined part is formed between the mouths. In addition, although this invention has the same effect with respect to all the passenger conveyors, such as an up-and-down escalator and a moving sidewalk, below, only a down escalator is demonstrated and other description is abbreviate | omitted.

  In FIG. 1, 1 is a truss that supports the weight of the escalator and the load, 2 is a lower entrance / exit, 3 is an upper entrance / exit, and 4 is between the upper entrance 3 and the lower entrance 2. The stepping plate 5 that circulates and moves is a moving handrail that circulates so that the upper end of the stepping plate 4 is synchronized with the forward path side of the stepping plate 4. The balustrade 8 is a manual portion corresponding to a portion of the balustrade 6 that is provided at the lower entrance 2 and the upper entrance 3 and protrudes from the tread plate 4 toward the entrance.

  The user 8 of the passenger conveyor grips the moving handrail 5 before getting on the tread board 4 at the upper entrance 3 and releases the hand from the moving handrail 5 after getting off the tread 4 at the lower entrance 2. Be prepared for. Further, the traveling direction of the moving handrail 5 is reversed in the manual section 8, and the traveling direction of the movable handrail 5 that moves in the manual section 8 is upward (upward) in the upper entrance 3 serving as the entrance. In the lower entrance 2 serving as a mouth, the traveling direction of the moving handrail 5 that moves in the manual section 8 is downward (downward).

  Next, the structure of the lower entrance / exit 2 which becomes an exit is demonstrated. In addition, since the upper boarding gate 3 used as a boarding gate has the structure similar to the lower boarding gate 2, the detail is abbreviate | omitted. At the lower entrance 2, a detection device 9 that operates the step board 4 and the moving handrail 5 when a user is detected is disposed between the detection device 9 and the manual unit 8, and from other than the detection position of the detection device 9. An entry prevention fence 10 is provided for preventing the user from getting on and off and guiding the user to get on and off from an appropriate place.

  Here, the detection device 9 detects, for example, a user who passes between the photoelectric posts 9a and 9b provided on both sides of the lower entrance 2 at a predetermined distance from the tread board 4, and is provided in the photoelectric post 9a. When the light from the light projector (not shown) cannot be received by the light receiver (not shown) provided on the photoelectric post 9b, the escalator is activated on the assumption that the light is blocked by the user.

  Further, the ingress prevention fence 10 is arranged so as to be arranged over the back side of the manual part 8 from the photoelectric post 9a to the photoelectric post 9a side and from the photoelectric post 9b to the back side of the manual part 8 on the photoelectric post 9b side. Standing on both sides of the entrance / exit 2, the end portion on the side of the manual portion 8 of each entry prevention fence 10 is configured to be movable by an external force.

  Specifically, movable protrusions 11a to 11c having a plurality of bar shapes projecting toward the respective nut portions 8 are provided on the end portions of the respective entrance prevention fences 10 on the side of the respective nut portions 8 so as to be provided vertically. 11c is configured to be independently movable by an external force. Here, the movable protrusions 11a to 11c are configured such that the movable protrusions 11a to 11c themselves are made of an elastic body such as rubber, and the movable part 11a to 11c is movable in any direction on the side of the nual portion 8. Alternatively, the detection device 9 side of each of the movable protrusions 11a to 11c may be configured with an elastic body such as a spring or rubber, and the nut portion 8 side made of a plastic body may be configured to be movable in any direction. .

  2 and 3 show a state in which a foreign object 12 such as a user's baggage is caught in the moving handrail 5 at the lower entrance 2. In such a state, the foreign object 12 comes into contact with the end of the approach prevention fence 10 on the side of the manual part 8, so that the movable protrusions 11 a to 11 c are deformed to the lower side and the outside of the entrance / exit, and the driving device for the moving handrail 5 The load acting on the foreign material 12 itself can be greatly reduced. Therefore, it is possible to prevent the escalator from being urgently stopped by operating the safety device when the foreign object 12 is caught in the moving handrail 5. Further, even when a user's hand or clothes are sandwiched between the moving handrail 5 and the entry prevention fence 10, the movable protrusions 11a to 11c are easily deformed, so that the user is injured or pinched. Thus, it is possible to prevent accidents such as a user falling down due to the loss of clothes, and a safer passenger conveyor can be provided.

  In the first embodiment, the end portion of the approach prevention fence 10 on the side of the manual part 8 is configured to be movable in all directions, but the handrail 5 that moves the part of the manual part 8 on the side of the manual part 8 moves. If it is movable to either the upper side or the lower side (the upper side at the entrance, the lower side at the exit) and / or the outside of the entrance, which is the traveling direction of the vehicle, a certain degree of effect It is possible to play.

  Further, in the first embodiment, the end portion 8 of the entry prevention fence 10 is configured to be movable by an elastic body such as rubber, and the foreign matter 12 sandwiched between the moving handrail 5 and the entry prevention fence 10 is provided. Although the case where the nual portion 8 side end portion of the entry prevention fence 10 that has been deformed is returned to the original state when it has been removed has been described, a predetermined load is applied to the end portion of the entry prevention fence 10 on the nual portion 8 side. It may be configured to be movable so as to be plastically deformed when acting. In such a case, the load that causes plastic deformation of the end portion 8 of the entry preventing fence 10 is deformed, for example, before the escalator stops emergencyly due to the load acting on the driving device of the moving handrail 5. The end portion of the entrance prevention fence 10 is set to a value such that the end portion of the end portion 8 is plastically deformed, or the hand or finger sandwiched between the moving handrail 5 and the entrance prevention fence 10 is injured. The effect can be expected particularly by setting the value to such a value that the part is plastically deformed.

It is a side view of the passenger conveyor in Embodiment 1 of this invention. It is a principal part enlarged view of the passenger conveyor shown in FIG. It is a principal part top view of the passenger conveyor shown in FIG.
