Description

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

[Conventional technology]

Figures 9 to 15 are, for example, published in Japanese Patent Application Laid-Open No. 57-13728.
These are steps of an escalator 1 shown as a conventional example in Publication No. 2.

In Figure 9, 1 is an escalator, and 2 is an escalator for carrying passengers.
C is a step that carries vertically, and a large number of steps 2 are connected endlessly by links, and in the middle part A of a constant inclination angle, adjacent steps 2 run in a stair-like manner, and the steps 2 are connected to the platform 3.
Adjacent steps 2 are lined up horizontally at both ends C close to , and in a section B where the opening inclination angle between the middle part A and both ends C changes, the vehicle travels with varying step-like 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 above-mentioned tread plate 4 glue 1)-) 41 has a front end 411 that protrudes every other length, and the front end 411 protrudes 17-
The rear end 412 of the top 41 is at the depth L of the groove 52 of the riser board 5.
The rear end 414 of the cleat 51 of the riser 5 protrudes with a width T along with the adjacent groove 42 by the height iLL of the cleat 51 of the riser 5, and the front j1413 does not protrude. The upper plate 5 has a cleat 51 having the same width as the cleat 41 of the tread plate 4 from which the rear end 414 protrudes.
A groove 52 having the same width as the width of the cleat 41 from which the rear end 412 does not protrude is provided, and the pitch P2 of the cleat 51 and the groove 52 is twice the pitch P1 of the cleat 41 of the tread plate 4. The width (length) T2 of 51 is
The width T of the cleat 41 of the footboard 4 is approximately 3.5 times that of the width T of the cleat 41 of the footboard 4.

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

The steps 2 configured as described above, when the escalator 1 is operated upward and travels in the direction of the arrow in Fig. 719,
When passing through section B between middle part A and both ends C, 1
With respect to the immediately adjacent step 2, the step-like step difference is gradually reduced, and the relative position changes horizontally as shown from EF to G in FIG.

[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 cleat 51 of the riser 5, especially if the footwear 9 has a high coefficient of friction such as rubber shoes, the toe 91 is bent downward by frictional force,
While the step 2 moves from a staircase shape to a horizontal shape, it may bite into the meshing part of the tread 4 glue 17-) 41 and the cleat 51 of the riser board 5, and the meshing distance between both 17-) 41 and 51 becomes the tread board. Since the footwear 4 remains constant from a step-like shape to a horizontal shape, once the footwear 9 gets wedged in, it is difficult to pull it out, and there is a problem that the footwear 9 may run into the landing area 3, resulting in an accident resulting in injury or death.

This invention solves the above-mentioned problem, and even if the tip of the passenger's footwear, such as the toe, digs into the engagement area between the cleat of the tread and the cleat of the riser, when the cleat of the tread board and the cleat of the riser board are in a stepped position, both cleats are The purpose of the present invention is to provide highly safe escalator steps that either come off naturally or easily with a small amount of force.

[Means for solving the problem, α]

The escalator step according to the present invention has a plurality of floorboards, a building floor, and a gap between the floorboards whose entire circumference is closed with an elastic body.

[Effect]

In this invention, with the above-described configuration, even if the toes of a passenger's footwear such as rubber shoes get stuck in the meshing part between the cleat of the tread and the cleat of the riser when the adjacent steps are in the shape of a staircase, both the cleats of the tread and the cleat of the riser can The engagement depth of the cleats gradually becomes shallower as the cleats move from the stepped to the horizontal, so in the horizontal area, the toe of the footwear may come off naturally or with a slight force from the area where the cleats engage. This prevents the driver from running into the boarding area while the vehicle is still wedged in.

〔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. In the tread #Ji2 of this embodiment, the height of the cleat 51 and the depth of the groove 52 are changed from the side opposite to the tread plate 4 to the side of the tread plate 4 by making the curvatures of the cleat 51 and the groove 52 of the riser board 5 different. When the step 2 is in the shape of a step, the engagement distance a between the cleat 41 and the protruding end 411 of the cleat 41 provided on the tread 4 of the next adjacent step 2 is adjusted so that it becomes smaller as the step 2 is stepped. Cleat 5
1 and the front end of the groove 42 of the tread 4 is large when the steps are arranged in a stepped shape, and decreases as the steps are 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 41 of the cleat 41 of the step board 4
1 engages with a deep groove 521 and a shallow groove 52
2 are alternately formed with pitches P and P, and a groove 521 is formed.
, 522 are opposed to the cleats 41 of the footboard 4, respectively, and the pitch P3 is made larger than P. It should be noted that the above-described unexpected structure of this embodiment is similar to the conventional structure shown in FIGS. 10 to 15.

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. Because it is difficult to reach the gap between the cleats 51 of 5,
The toe 91 becomes difficult to bite into the meshing portion of the cleats 41 and 51.

Furthermore, 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 as shown in D-E→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, 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 contact P of the groove 521 that the protruding front end 411 of the groove 521 engages with is large, and the front end 413 of the cleat 41 of the tread plate 4
The depth of the groove 522 from the tip of the groove 522 that does not engage with the beam 17-) is shallow, and the draft angle can be made gentle. Therefore, in this embodiment, when casting the riser plate 5, there is less wear and tear on the mold. Suitable for mass production.

In the above embodiment, the tread plate 4 (217-) 41 and groove 42, and the riser plate 5's cleat 51 and groove 5
Although the cleat 41 of the tread plate 4 has been shown to be constructed of a peeled material, the present invention also includes a cleat 41 of the tread plate 4, as shown in FIGS. 6 and 7.
The groove 42, the cleat 51 of the riser plate 5, and the groove 52 may be formed by press molding of a thin steel plate.

In addition, in this invention, as shown in FIG. 8, among the cleats of the riser board 5, the pitch P4 is small,
1 A narrow protrusion 0415 from the front nA413 of the cleat 41 of the tread 4 in the shallow part of the groove 522 from the tip.
By engaging these, it is possible to secure a gap between the cleat 51 of the groove 521 of the riser board 5 having a large pitch P3 and the cleat 41 of the tread board 4, and also to secure the gap between the cleat 41 of the step board 4, the cleat 51 of the riser board 5, and the step 2. The gaps in the width direction become narrower, making it difficult for dirt and foreign objects 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. By interlocking the protruding ends of the cleats provided on the treads of one adjacent step with the cleats provided on the treads of the other step, the cleats are deeply interlocked when they are in a stair-like shape, and become shallower as they are lined up horizontally. Even if the tips of the visitor's footwear, such as the toes, get stuck in the meshing area between the tread cleat and the riser cleat when they are stepped, they will come off from the meshing area between both cleats naturally or with a small amount of force in the horizontal area. This has the effect of providing highly safe escalator steps so that footwear does not fall into the boarding area.
