  In the above Patent Documents 1 and 2, only a configuration in which a caution band is fixed to the four peripheral edges of the step body is disclosed, and this brings about a width dimension setting of each caution band greatly related to ensuring the safety of passengers on the step body. There was no specific mention of improving visibility and alerting effect. And when the width of the front caution band is narrow, when the front caution band is viewed from the height of the passenger's eyes, it is obstructed by the convex curved surface portion of the riser body of the step body that is located adjacent to the front. , There was a problem that there was a fear that it would not be used. Further, in Patent Document 3, the width dimension of the caution marking part by painting the front part is shown to be slightly larger than that of the rear part, but the caution difference effect is not sufficient only by the dimensional difference by this illustration. There was a risk of causing the same problem as in References 1 and 2. Furthermore, as a matter common to these cited references, there was no consideration of enhancing the alertness of the foot warning light provided near the entrance / exit.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a passenger conveyor step body that can increase safety by enhancing the alertness of the cleat body on the upper surface of the step body, in particular its front caution band.

  To achieve the above object, the present invention provides a horizontally disposed cleat body, a rear end portion of the cleat body and an upper end portion thereof connected, a riser body having a convex curved portion and extending downward, The base is fixed to the front edge of the cleat body, and a front caution band having an extended portion extending toward the riser body at the adjacent front portion, and a rear edge of the cleat body, In a passenger conveyor step body comprising a rear caution band to which the base is fixed and side caution bands fixed to both side edges of the cleat body, the width dimension before and after the rear caution band and the side The lateral width dimension of the front caution band and the base width dimension before and after the front caution band are substantially the same as about 20 mm, and the full length width dimension before and after the front caution band is the same as the rear caution band and the Consists of approximately 30 mm or more, approximately 1.5 times the width of the side caution band There.

  According to the above configuration, when looking down on the top surface of the cleat body of the step body located in front of it from the height of the eyes of a passenger with a very average height on the specific step body, all the front caution bands are adjacent to each other. It is not obstructed by the convex curved surface portion of the riser body of the step body located in the front, and the front caution band exhibits the original alertness and can contribute to the prevention of personal injury in the gap between the adjacent step bodies. In particular, by setting the overall width of the front caution band to approximately 1.5 times the width of the rear caution band, the degree of obstruction by the convex curved surface portion of the riser body located in front is reduced. , Stable visibility can be provided. Furthermore, by extending the full length width of the front caution band, the extension part that does not have the bottom part except for the base width is substantially extended, and the caution light of the foot caution light passes near the entrance / exit, Since it exerts the function of strongly appealing and visually recognizing the attention beam to the passenger, it can further contribute to the improvement of safety.

  According to the step body of the present invention, the safety of the cleat body on the upper surface of the step body, in particular, the attention warning of the front caution zone can be further increased.

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

  FIG. 1 is a conceptual side view of the vicinity of the upper part showing an embodiment according to the present invention, FIG. 2 is a rear view of the step body used in FIG. 1, and FIG. 3 is a cross-sectional view taken along the line II of FIG. is there.

  In the figure, an escalator 1 which is a kind of passenger conveyor is installed from a lower floor (not shown) to an upper floor F, and is connected to an endless chain 2 to move, and this step body. 3 is a system that transports passengers with a moving body of a handrail 4 that moves in synchronization with the vehicle 3. These moving bodies are driven by the rotation of the drive vehicle 10 through the drive chain 9 from the drive unit 8 composed of the motor 6 and the speed reducer 7 that are rotated by the electrical command of the control device 5, respectively. It is a mechanism that moves along the balustrade 12, and in many cases, a caution beam is emitted from the gap between the step bodies 3 by the foot caution light 14 at a lower position near the getting-on / off floor 13, as indicated by an arrow M, between the step bodies 3. Informs that the boundary gap is a dangerous area.

  The step body 3 includes a horizontally disposed cleat body 31, a rear end portion 31A of the cleat body 31 and an upper end portion 32A thereof, and a riser body 32 having a convex curved surface portion 32A and extending downward. A pair of left and right substantially triangular bracket bodies 33 that support the cleat body 31 and the riser body 32 at both ends in the width direction are provided.

  Furthermore, the front wheel 34A and the front wheel 34 that are respectively supported by the main shaft 35A and the main shaft 35A on the front end portion 31B side of the cleat body 31 and the lower end portion 32C side of the riser body 32, that is, the front end portion 33A and the lower end portion 33B of the bracket body 33, A rear wheel 35 is provided, and the front wheel 34 and the rear wheel 35 move on the guide rail 11 and change direction on the lower side of the passenger floor 13.

  Furthermore, the tread structure of the step body 3 and the cleat body 31 according to the present invention will be described. The cleat body 31 includes a large number of uneven portions 31C on the surface portion thereof, and a rear caution band 31F of the front and rear width dimension W1 having a base portion 31f connected to the bottom portion of the uneven portion 31C at an end portion 31A of the rear edge thereof. The front end portion 31B of the front edge includes a base portion 31g having a front and rear base width dimension W33 connected to the bottom portion of the uneven portion 31C, and an extended portion 31gg extending toward the riser band 32 of the adjacent front portion except for the base portion 31g. A front caution band 31G having a front and rear full length width dimension W3 and a side caution band 31H having a width dimension W2 are fixed to the side end portions 31D and 31E of both side edges, respectively. Prevents the intrusion of shoes and foreign objects into the boarding / exiting floor 13.

  In addition, the total four bodies of the caution bands 31F, 31G, and 31H are made of a synthetic resin material having a caution color such as yellow, and are configured devices (step bodies) that are positioned with a certain gap around the four peripheral edges of the cleat body 31. It exerts an alerting action that prevents passengers from getting close to each other or skirt guards.

  Here, in the present invention, the width dimension W1 of the base part 31f of the rear caution band 31F is set to about 20 mm, and the width dimension W2 of the side caution band 31H is set to about 20 mm, similarly to the width dimension W1, and the base part of the front caution band 31G is set. The width dimension W33 of 31g is also set to about 20 mm, and the total length width dimension W3 is 30 mm or more, that is, the dimension ratio of W1 to W3 is W1 <W3, W2 <W3, W33 <W3, and W3≈1.5W1 or more. It is characterized by that.

  The reason for this setting will be described with reference to FIGS. In FIG. 1, when a passenger stands on a specific step body 30 and looks down on his / her feet from the position E of the passenger's eyes, the convex curved surface portion 32 </ b> B has a curvature radius R included in the step body 3 adjacent to the front of the specific step body 30. The riser body 32 to be formed is obstructed, and the line of sight becomes a line S, which results in making the width dimension of the front caution band 31GG (identical to the reference numeral 31G) of the specific step body 30 narrowly visible. This situation is unacceptable because it is a part where many accidents occur due to pinching of the shoe tip or the like in the mutual gap X part.

  For example, even when the passenger's height is somewhat higher than the average height, the above-mentioned width dimension is set so that the front caution band 31GG can be visually recognized (in the case of FIG. 3, the portion corresponding to the width W4), and safety is enhanced by enhancing the alertness. Is. Further, the extending portion 31gg having no bottom corresponding to the base portion 31g, which is the difference between the full length width size W3 and the base portion width dimension W33, improves the warning effect by the attention beam as shown by the symbol M in FIG.

  In addition, although demonstrated by the example of the escalator 1 as a passenger conveyor, this invention is not limited to this, It can apply also to the moving walk which uses the step body 3 of a similar form.

It is a conceptual side view near the upper part of the passenger conveyor which shows one Embodiment of this invention. It is a rear view of the step body single body shown in FIG. It is sectional drawing which follows the II line | wire of FIG.
