Description

[Detailed description of the invention] [Public funds for industrial use] This invention relates to an escalator tread.

[Prior art] Figures 3 to 7 are, for example, those of Utility Model Publication No. 57-137282.
These are the steps of an escalator 1 shown as a conventional example in the publication.

In Fig. 3, l is an escalator, 2 is a step for carrying passengers, a large number of steps 2 are connected endlessly by links, and the steps 2 are at an intermediate part A with a constant inclination angle.
In section B, the adjacent steps run side by side in a step-like manner, and at both ends C near the boarding area 3, adjacent steps 2 are lined up horizontally, and in section B, where the inclination angle between the middle section A and both ends C changes. The vehicle travels through changing step-like steps.

The steps 2 will be explained in detail with reference to FIGS. 4 to 7.

In these figures, 4 is a treadle or board for carrying passengers;
A large number of IJ-totes 41 and groups 42 are glued on the top surface of the treadle 4.
are provided alternately.

5 is a curved riser plate arranged in a substantially L-shape at the rear end of the tread plate 4, and a large number of cleats 51 and groups 52 are provided on the convex surface of the riser plate 5. Ribs 53 are provided on the upper end and on both left and right sides of the concave surface on the back side of the convex surface.

The front end 411 of the tread plate 4 (IJ-) 41 protrudes every other length by a length L, and the rear end 412 of the cleat 41 from which the front end 411 protrudes is attached to the bottom surface of the group 52 of the riser board 5 at a depth L. They are pulled in together, and the front end 413 does not protrude! J-) The rear end portion 414 of the riser plate 5 has a radius T together with the adjacent group 42 by the height L of the cleat 51 of the riser plate 5.
The riser board 5 is further provided with a cleat 51 having the same width as the cleat 41 of the tread board 4 with the rear end 414 protruding, and a group 52 with the same width as the width of the cleat 41 without the rear end 412 protruding. It is being

Reference numeral 7 denotes a roller attached to the bracket 6 via a shaft 8. The shaft 8 is connected to a link, and the roller 7 is guided by a guide rail so that the step 2 can run.

When the steps 2Lt and the escalator 1 configured as described above are operated upward and run in the direction of the arrow in FIG. 3, when passing through the section B between the intermediate section A and both ends C,
With respect to the immediately preceding step 2, the relative position changes horizontally as shown from E→F→G in FIG. 7 by gradually reducing the step-like step difference.

[Problem that the invention seeks to solve]

In the conventional escalator steps as described above, as shown in FIG. If the shoes have a large coefficient of friction, such as rubber shoes, the toe 91 is bent downward by the frictional force, and the cleat 41 of the tread 4 and the cleat 51 of the riser 5 are bent while the step 2 moves from the step shape to the horizontal shape. It may bite into the meshing part, and in this state it may crash into the landing base 3, resulting in an accident resulting in injury or death.゛In order to prevent the above-mentioned accident where the footwear 9 gets wedged between the tread 4 and the riser 50 of the adjacent steps 2, it is necessary to greatly change the meshing distance between the cleats of the tread and the riser, and to change the width of the riser. It is effective to reduce the 1!8 coefficient of the convex surface, but
In addition, it is also effective to increase the rigidity of the riser.

However, increasing the overall rigidity of the riser increases the weight of the entire step, requires a large amount of power to drive the step, and increases the cost of the step.

Otsu's invention solves the above-mentioned problems and reduces the increase in weight, but the required part of the riser has a large rigidity, which prevents footwear from getting wedged between the tread and the riser, resulting in safety. The purpose is to provide high escalator steps.

[Means for solving problems]

In the escalator step according to the invention of Party B, the rib of the riser board is enlarged near the top end of the step board.

[For production]

In the invention of O, the escalator steps are simply made larger by increasing the ribs of the riser near the tread as mentioned above, so the increase in weight is small, but the toes of the footwear are connected to the riser and the tread. This bite is thick (
Because the rigidity of the riser near the horizontal part is greater than that in other parts, it is difficult for the toes of the footwear to get stuck between the riser and the tread in the horizontal part.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG.

FIG. 1 shows an embodiment of the present invention, and the same reference numerals in FIG. 1 as in FIGS. 3 to 7 indicate the same or corresponding parts.

In the step 2 of this embodiment, the curvatures of the cleat 51 and the group 52 of the riser board 5 are made different, so that the height of the cleats 1 and 51 and the depth of the group 52 can be changed from the opposite side of the tread plate 4 to the side of the tread plate 4. Gradually shape the ingredients so that they become smaller as the size increases.
The meshing distance α between the cleat 51 and the protruding end 411 of the cleat 41 provided on the tread 4 of the next adjacent step 2
When the steps 2 are step-shaped, they are deep, and as they are lined up horizontally, they become shallow (as well as the group 4 of the cleat 51 and the tread 4).
The overlapping margin β with the front end of No. 2 is large when the steps are shaped, and becomes small as the steps are arranged horizontally.

Furthermore, the tread plate 4 of the rib 53 provided on the back side of the convex surface of the riser plate 5
The left and right upper end portions 531 close to the riser board are made to protrude forward in a substantially triangular shape, and the upper end horizontal portion 532 is lengthened to increase the rigidity of the upper end portion of the riser board.

The configuration of this embodiment other than the above is the same as the conventional one shown in FIGS. 3 to 7.

Since the steps of this embodiment are constructed as described above, when the adjacent steps 2 are step-shaped, as shown in A of FIG. Since the overlapping margin β of the cleats 1 and 51 of the riser 5 of the other step 2 is large, the toe 91 of the footwear 9 such as rubber shoes of the passenger riding on the tread 4 overlaps the cleat 41 of the tread 4 and the riser. Board 5
Since it is difficult to reach the gap between the cleats 51, the toe 91 becomes difficult to bite into the meshing portion between the cleats 1 and 41 and 51.

Further, in this embodiment, even if the toe 91 of the footwear 9 bites into the meshing portion of the cleats 41 and 51, the meshing distance α becomes shallower as the shape becomes horizontal from A to B to C in FIG. , toe 91 on the horizontal part
It either comes off naturally from the meshing part, or it comes off easily with a small amount of force.

Further, the steps of this embodiment have an upper end portion 531 of the rib 53 of the riser board 5. Since the upper end horizontal portion 532 is large, the riser board 5
The rigidity of the upper end portion is large, and the toe 91 of the footwear 9 is difficult to bite into the engagement portion between the cleat 41 of the footboard 4 and the cleat 51 of the riser board 5 at or near the horizontal portion.

FIG. 2 shows another embodiment of the present invention, and in FIG.
The same reference numerals as in the figures indicate the same or corresponding parts. In this example, the height of the cleat 51 of the riser 5 and the group 5
The depth dimension of 2 is the same from the side opposite to the tread plate 4 to the side of the tread plate 4, and the rib 53 of the riser plate 5 is gradually enlarged as it approaches the tread plate 4. Therefore, in this embodiment, the rigidity near the upper end of the riser board 5 is made greater than other parts, so that the toe 91 of the footwear 9 is connected to the tread plate 4 (IJ-) 41 in the horizontal area and in the vicinity thereof. It becomes difficult for the cleat 51 of the plate 5 to bite into the meshing part.

〔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 groups are alternately provided on the upper surface, and a riser plate in which a large number of cleats and groups are provided in an alternating manner on the convex surface. Since the ribs of the riser are made larger near the top of the riser, the rigidity near the top of the riser is greater than other parts, allowing the toes of the footwear to be placed between the tread and riser of the adjacent step. This has the effect of being able to provide escalator steps that are less likely to dig in, improving safety, adding little to the overall weight of the steps, requiring almost no increase in the power required to drive the steps, and not increasing costs too much. It will be done.
