[Detailed description of the invention] [Industrial application field] This invention relates to an escalator tread.

[Conventional technology]

Figures #49 to 15 are from, for example, Japanese Patent Application Laid-Open No. 57-1372.
These are the steps of an escalator 1 shown as a conventional example in Japanese Patent No. 82.

In Fig. 9, 1 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 stair-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 runs through changing steps.

The steps 2 will be explained in detail with reference to FIGS. 10 to 15. In these figures, numeral 4 is a treadboard on which a passenger rides, and the top surface of the treadboard 4 has many cleats 41 and grooves 42.
are provided alternately.

Reference numeral 5 denotes a curved riser plate disposed in a substantially L-shape at the rear end of the footboard 4, and a large number of cleats 51 and grooves 52 are provided on the convex surface of the riser plate 5.

The front end 411 of the cleat 41 of the tread 4 protrudes every other length, and the front end 411 protrudes (17-)
The rear end 412 of the cleat 41 is aligned with the bottom surface of the depth L of the groove 52 of the riser board 5 and pulled out, and the rear end 414 of the cleat 41 whose front end 413 does not protrude is aligned with the bottom surface of the groove 52 of the riser board 5 at a depth L.
The riser board 5 has a cleat 51 having the same width as the cleat 41 of the tread board 4 with a protruding rear end 414 and a protruding rear end 412 with a width T. A groove 52 having the same width as the width of the cleat 41 is provided, and the pitch P2 of the cleat 51 and the groove 52 is equal to 2 of the pitch P1 of the cleat 41 of the tread 4.
The width (length) T2 of the cleat 51 is approximately 3.5 times the width T1 of the cleat 41 of the footboard 4.

7 is a roller attached to the bracket 6 via a pongee 8, the shaft 8 is connected to a link, the roller 7 is guided by a guide rail, and the steps 2 are run. When the escalator 1 is operated upward and travels in the direction of the arrow in FIG. 9, the step 2 configured as shown in FIG. With respect to the step 2 adjacent to the step 2, the relative position changes horizontally as shown from EF to G in FIG. 15 by gradually reducing the step-like step.

[Problem to be solved by the invention]

In the conventional escalator steps as described above, the tread 4
Since only every other cleat 41 has a protruding front end 411, the gap S in the step width direction between the protruding front ends 411 is long, and foreign objects such as the toes of passengers' footwear, the tip of an umbrella, and dirt can There was a problem with it getting stuck. If the front ends of the cleats of the treads are all made to protrude with the same width, casting becomes difficult because the cleats are usually integrally molded with the treadboards and riser plates from metal castings. In other words, the gap in the width direction of the step between the protruding front end of the tread cleat and the riser cleat must be a certain size to prevent contact due to vibrations caused by running the steps. If the width of the front end portion is made the same and a gap of a predetermined size is to be secured, the cleat of the riser plate must be molded to a width narrower than the minimum thickness required for casting, which makes the structure difficult.

This invention solves the above-mentioned problems and improves passenger footwear.
The aim is to provide escalator steps that are highly safe, prevent foreign objects from getting caught, and are suitable for mass production.

[Means for solving problems]

The escalator step according to this invention has a wide and long protruding end of the tread cleat with a wide and deep groove of the riser, and a narrow and short protruding end of the tread cleat with a wide and deep groove of the riser. The grooves are arranged alternately with narrow and shallow grooves facing each other.

[Effect]

In this invention, as configured as described above, the cleat of the step is provided with end portions that protrude across the entire width direction, thereby shortening the gap in the width direction of the step between these end portions to prevent footwear and foreign objects from entering the step. In addition to preventing the tread from getting caught in the gap, the tread cleat has a wide, protruding end and a narrow, short protruding end that alternate between the tread cleat and the riser. Even if the gap in the step width direction of the cleat is set to a predetermined size, the cleats for the tread board and the riser board can be easily manufactured and are suitable for mass production.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 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
By making the curvature of the cleat 51 and the groove 52 different, the height of the cleat 51 and the depth dimension 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. The protruding end 411 of the cleat 41 provided on the tread 4 of the next adjacent step 2
When the steps 2 are in the shape of a step, the meshing allowance a is deep, and as the steps 2 are lined up horizontally, the engagement distance a becomes shallower. It's less. Also,
By forming unevenness alternately in the width direction of the step 2 on the riser board 5, wide and deep grooves 521 and narrow and shallow grooves 522 are alternately formed.
1 has a wide and long protruding end 41 similar to the conventional one.
1 and a narrow and short protruding end 415 from the front end 413 are formed alternately, and the pitch Po of the cleat 41 is set to P,
It's bigger. A wide and long protruding end 41 of 17-) 41 is provided on the tread 4 of the adjacent step.
1 is engaged with a wide and deep groove 521 of the riser board 5, and a narrow and short protruding end 415 of the cleat 41 is engaged with a narrow and shallow groove 522 with a gap provided therebetween.

The above-mentioned unexpected configuration of this embodiment is shown in FIG. 115.
It is similar to the conventional one shown in the figure.

Since the steps of this embodiment are constructed as described above, when the adjacent steps 2 are in the shape of a step, as shown in FIG. Since the overlapping margin β of the cleat 51 of the riser 5 of the other step 2 located at 2 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. 5 glue 17-) Since it is difficult to reach the gap between 51, it becomes difficult for the toe 91 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 cleats 41 and 51, the meshing distance α is horizontal from D-E to F-G in FIGS. 1 and 5. As the surface becomes shallower, the toe 91 either naturally comes off the engagement part in the horizontal part, or easily comes off with a small amount of force.

Furthermore, in this embodiment, the wide (long protruding end 411) of the tread plate 4 (glue 17-) 41 is inserted into the wide and deep groove 521 of the riser plate 5, and the narrow and short protruding end of the cleat 41 is Since the portions 415 are engaged with the narrow and shallow grooves 521 and arranged alternately, the glue 17 of the tread plate 4 is
-) 41 is provided with end parts 411 or 415 that protrude from the entire step width direction, so that the gap between these end parts in the step width direction is shortened, and the toe of the passenger's footwear, the tip of the umbrella, Foreign matter such as dust is less likely to get caught in the gap.

The tread and riser of normal steps are made integrally by casting, and if the cleat is high, it is necessary to maintain a specified gap between the cleat of the step and the cleat of the riser. The draft angle of the cleat becomes steep, and the casting is heavily consumed, making it unsuitable for mass production.
1, the pitches of the grooves 521 are wide and are engaged with the wide and long protruding front end 411 of the tread 4, and grooves 522 are engaged with the narrow and short protruding front end 415 of the tread 4. Because it is narrow and shallow, the draft angle can be made gentler, and there is less wear and tear on the mold when casting. Further, in the cleat 41 of the tread plate 4 of this embodiment, the wide and long protruding front end portion 411 and the narrow and short protruding front end portion 415 are arranged alternately. Since the required minimum wall thickness for manufacturing can be thin, the required minimum thickness can be maintained, it can be easily cast, and productivity is high. Therefore, this embodiment is suitable for mass production.

In addition, in this invention, as shown in FIG.
The short protruding end 415 of the cleat 41 may be formed into a substantially trapezoidal shape in its tapered plane.

Further, 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. 7 and 8, 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 thin steel plate. A press molded product may also be used.

Further, the present invention can be applied to a riser in which the cleat height is the same from the end opposite to the tread plate to the end on the tread plate side.

〔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 wide, long, protruding ends of the tread cleats are placed in the wide, deep grooves of the risers, and the narrow, short, protruding ends of the cleats are placed in the narrow, shallow grooves, facing each other in an alternating manner. As a result, it is possible to provide escalator steps that are less likely to get caught in footwear, foreign objects, etc., are highly safe, are highly productive, and are suitable for mass production and are inexpensive.
