[Problem to be solved by the invention]

In the conventional escalator steps as described above, the 15th
As shown in the figure, when a passenger riding on the tread 4 presses the toe 91 of his/her footwear 9 against the glue 17-) 51 of the riser 5, especially when the footwear 9 has a high coefficient of friction such as rubber shoes, , there is a problem that the toe 91 is bent downward by the frictional force and may bite into the meshing part of the cleat 41 of the tread 4 and the cleat 51 of the riser board 5 while the step 2 is moving from a staircase shape to a horizontal shape. there were.

The present invention solves the above-mentioned problem and provides a highly safe escalator step in which the toes of a passenger's footwear are less likely to bite into the engagement portion of the cleat of the tread and the cleat of the riser when the step is shaped. I have a purpose.

[Means for solving problems]

In the escalator steps according to the present invention, the ends of the grooves of the treads and the cleats of the risers are overlapped more often in the step-like shape, and less as they are arranged horizontally.

[Effect]

In this invention, since the structure is as described above, when the steps are step-like, the overlapping distance between the groove and the riser board can be compared to that of a conventional staircase where the overlapping distance is the same as when the steps are arranged horizontally. Since it is difficult for the toes of passengers' footwear such as rubber shoes to reach the mating part between the protruding end of the tread cleat and the cleat of the riser board, it is difficult for the toes of the passenger's footwear, such as rubber shoes, to get into the mating part. It's a monkey.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to Figures @1 to Figures @8.

1 to 5 show an embodiment of the present invention, and in these figures, the same reference numerals as in FIGS. 10 to 15 indicate the same or corresponding parts. The steps 2 in this embodiment have risers 5
217-) By making the curvature of 51 and the groove 52 different, the height of the cleat 51 and the depth of the groove 52 are gradually made smaller from the side opposite to the tread plate 4 to the side of the tread plate 4. 17-) Provided on the tread plate 4 of the step 2 adjacent to 51 one step later, or 17-) The engagement distance a between the protruding end portion 411 of 41 is deep when the step 2 is in the shape of a step, and becomes shallower as the step 2 is arranged horizontally. Along with Cleat 5
1 and the front end of the groove 42 of the footboard 4 is also large when the step is shaped like a step, and decreases as it is arranged horizontally. In addition, by forming unevenness alternately in the width direction of the step 2 on the riser board 5, the protruding front end 4 of the cleat 41 of the step board 4
11 engages with the deep groove 521 and the shallow groove 5
22 are alternately formed with pitches P and P4, and grooves 52
The cleats 41 of the footboards 4 are opposed to each other at 1.522, and the pitch P is larger than P4.

In addition, the configuration of this embodiment other than the above-mentioned is! It is the same as the conventional one shown in @10 to 15.

Since the steps of this embodiment are constructed as described above, when the adjacent steps 2' are step-shaped as shown in FIG. 1(D), the groove 42 of the tread 4 of one step 2, Since the overlapping margin β of the cleat 51 of the riser 5 of the other step 2 located in front is large, the toe 91 of the rubber shoe-like footwear 9 of the passenger riding on the tread 4 overlaps the cleat 41 of the tread 4 and the riser. Since it is difficult to reach the gap between the cleats 51 of the plate 5, the toe 91 becomes difficult to bite into the meshing portion of the cleats 41 and 51.

Further, in this embodiment, even if the toe 91 of the footwear 9 bites into the meshing portion of the original creases 141 and 51, the meshing distance a is changed from D-4E to F-4G in FIGS. 1 and 5.
The toe 91 becomes shallower as it becomes horizontal, so that in the horizontal part, the toe 91 either comes off naturally from the engagement part or easily comes off with a small amount of force.

Furthermore, normal risers are made in one piece by casting, and if the height of the cleat is high, it is necessary to secure a gap at the front end of the cleat of the tread, which results in a steep draft angle of the cleat, and Although this embodiment suffers from heavy wear and tear and is unsuitable for mass production, in this embodiment, the grooves 52 of the riser board 5 and the pitches of the cleats 51 are alternately different, and the pitch of the cleats 41 of the tread board 4 is different.
The pitch P of the groove 521 with which the protruding front end 411 engages is large, and the front end 41 of the tread plate 4 (17-) 41
3 is the glue that does not engage, n portion of the groove 522 is the cleat 52
The depth of the groove 522 from the tip of the groove 522 is shallow, and the draft angle can be made gentle. Therefore, in this embodiment, there is less mold wear when casting the riser plate 5, and it is suitable for mass production.

In addition, in the above embodiment, the cleat 41 and groove 42 of the tread board 4 and the cleat 51 and groove 52 of the riser board 5 are
However, as shown in FIGS. 6 and 7, the cleat 41 and groove 42 of the tread plate 4 and the cleat 51 and groove 52 of the riser plate 5 are made of a material that peels off the rear plate. A press molded product may also be used.

In addition, in this invention, as shown in FIG. 8, among the cleats of the riser board 5, the pitch P4 is small,
If the narrow protrusion 415 from the front 4413 of the cleat 41 of the tread board 4 is engaged with the shallow depth part of the groove 522 from the tip of the cleat 51 of the groove 521, the pitch P of the riser board 5 will be large. It is possible to secure a gap between the cleat 41 of the tread board 4 and the riser board 5.
The gap between the cleat 51 and the step 2 in the width direction becomes narrower, making it difficult for dirt and foreign matter to enter.

〔Effect of the invention〕

As explained above, the present invention provides steps for an escalator that includes a step in which a large number of cleats and grooves are alternately provided on the upper surface, and a riser plate in which a large number of cleats and grooves are provided in an alternating manner on the convex surface. The end of the groove provided on the tread of one adjacent step and the cleat provided on the tread of the other step are often aligned horizontally when the step is shaped like a staircase.
By overlapping less and less as the step F increases, when the steps are stair-like, it is difficult for the toes of the passenger's footwear to reach the engagement part between the tread glue 17-to and the cleat of the riser, and the tip of the footwear is This has the effect of providing a highly safe escalator step because the part is less likely to bite into the engaging part.
