Description

  This embodiment relates to a passenger conveyor.

  In passenger conveyors such as escalators and moving walkways, a number of steps attached to an endless step chain are circulated between a pair of entrances and exits. A moving handrail provided on the outer periphery is moved in synchronization with the steps.

  A boarding board is laid in the pair of entrances, and a comb mounting beam is provided on the lower surface of the boarding board. A comb is attached to the comb mounting beam so as to be positioned at the front end of the boarding / alighting plate, and the steps move in a substantially horizontal direction with a predetermined interval below the comb and the boarding / alighting plate (for example, See Patent Document 1 below).

  In such a passenger conveyor, when a passenger gets off from a step to a boarding board at the boarding gate, the boarding board is used in order to prevent the passenger from getting caught in the boarding board or toe toe between the step and the boarding board. The board is inclined so as to become lower toward the tip so as to reduce the vertical distance between the comb and the step provided at the tip.

JP 2009-84013 A

  However, depending on the building where the passenger conveyor is installed, the length dimension of the boarding board along the moving direction of the step may not be increased. In such a case, the distance between the comb and the step is less than the predetermined dimension. If set, the inclination angle of the boarding / exiting plate with respect to the horizontal plane becomes too large, so that there is a problem that the passenger feels uncomfortable or fearful, or that passengers can easily travel when getting off the platform from the step.

  The present invention has been made in consideration of the above problems, and even if the length dimension of the boarding board along the moving direction of the step is shortened, it is difficult to give the passenger a sense of incongruity and fear. The purpose of the present invention is to provide a passenger conveyor that is difficult to travel when getting off the board.

  The passenger conveyor of the present embodiment includes a step that is attached to an endless step chain and circulates between a pair of entrances and exits, a board and exit plate provided above the steps at the entrance and exit, and a tip of the board and exit plate And the board is provided with a first inclined portion that becomes lower toward the tip and a second inclined portion that bends downward from the tip of the first inclined portion. And

It is a side view showing a passenger conveyor concerning one embodiment of the present invention. It is a top view of the entrance / exit provided in the passenger conveyor of FIG. It is AA sectional drawing of FIG. It is a principal part enlarged view of FIG.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the passenger conveyor 1 of this embodiment shown in FIG. A passenger who has boarded the tread surface 2a of the step 2 is transported across the upper floor and the lower floor.

  A pair of left and right balustrades 10 are provided on both sides of the step 2, and a handrail belt 12 that circulates and moves in synchronization with the step 2 is attached to the outer periphery of the balustrade 10.

  On the tread surface 2a of the step 2, as shown in FIG. 2, a plurality of cleat ridges 13 extending in the moving direction M of the step are provided in parallel with each other at a predetermined interval. A cleat groove 14 is formed between the two.

  A number of steps 2 are connected by an endless step chain 3 and are arranged in a truss 4 installed under the floor of the building. A sprocket 5 and a drive device 6 having a drive motor and a speed reducer are disposed on the upper floor side of the truss 4, and a sprocket 7 is disposed on the lower floor side of the truss 4. As the sprocket 5 on the upper floor is rotationally driven by the output from the step chain 3, the step chain 3 spanned between the sprocket 7 on the lower floor side circulates and the step 2 moves from the lower floor to the upper floor. Or move from the upper floor to the lower floor.

  As shown in FIG. 1 and FIG. 2, a plurality of boarding boards 16 are laid side by side along the moving direction M of the step at the boarding gate 8 on the upper floor side and the boarding gate 9 on the lower floor side. A comb mounting beam 19 is provided on the lower surface of the approaching board 16a. A comb 17 is attached to the comb mounting beam 19 so as to be positioned at the tip of the boarding / alighting plate 16a, and the step 2 moves in a substantially horizontal direction below the comb mounting beam 19 and the comb 17.

  As shown in FIGS. 3 and 4, a comb tooth 18 that meshes with the cleat ridge 13 provided on the tread surface 2 a of the step 2 is provided at the tip of the comb 17. Scooping up foreign objects and foreign objects on the boarding / alighting plate 16a prevents the passenger's feet and foreign objects from being caught between the step 2 and the boarding / alighting plate 16a.

  In the passenger conveyor 1 having the above-described configuration, the boarding / alighting plate 16a closest to the step 2 side is inclined so as to become lower toward the tip (that is, the comb 17 side), and the tip of the first slope 30. A second inclined portion 32 that is bent downward from 30 a and is provided with a larger gradient than the first inclined portion 30.

  The first inclined portion 30 provided on the boarding / alighting plate 16a has an inclination angle θ1 with respect to the horizontal plane H set to 4 ° to 5 °, and the second inclined portion 32 has an inclination angle θ2 with respect to the horizontal plane H of 5 ° to 10 °, for example. In this embodiment, the inclination angle θ1 of the first inclined portion 30 is set to 4 °, and the inclination angle θ2 of the second inclined portion 32 is set to 7.9 °.

  Further, the comb 17 provided at the front end of the boarding / alighting plate 16 a is inclined so as to be smoothly connected to the second inclined portion 32 without an angle appearing at the joint portion between the second inclined portion 32 and the comb 17.

  As described above, in the passenger conveyor 1 according to the present embodiment, the boarding / alighting plate 16 a provided at the boarding gates 8 and 9 is lower from the first inclined part 30 and the lower side from the front end 30 a of the first inclined part 30. And a second inclined portion 32 which is bent toward the first inclined portion 30 and is provided with a larger gradient than the first inclined portion 30. The inclined portion 32 inclines downward more rapidly than the first inclined portion 30.

  As a result, the inclination of the second inclined portion 32 becomes less conspicuous with respect to the size of the inclination angle θ2 of the second inclined portion 32, so that the inclination angle of the boarding / alighting plate 16a is set large and along the moving direction M of the step 2 Even if the length of the boarding / alighting board 16a is shortened, when getting off the boarding board 16a from the step 2 at the boarding gates 8 and 9, it is difficult for passengers to feel uncomfortable or fearful and to go down when getting off the boarding board 16a from the stage. Become.

  Thus, by shortening the length dimension of the boarding board 16a along the moving direction M of the step 2, the comb mounting beam 19 that supports the boarding board 16a can be shortened, and is provided below the boarding board 16. Therefore, it is possible to secure a wide space in the machine room or to reduce the space required for installing the passenger conveyor 1.

  As mentioned above, although embodiment of this invention was described, this embodiment is shown as an example and is not intending limiting the range of invention. This embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. This embodiment and its modifications are included in the scope of the present invention and the gist thereof, and are also included in the invention described in the claims and the equivalent scope thereof.
