Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] This invention relates to escalator steps, and particularly to escalator steps that prevent slit-like gaps from forming between each step. be.

[Conventional technology]

In recent years, as the range of use of escalators has expanded,
Escalators are also being used for cross passages.

9 and 10 are, for example, Japanese Patent Application Laid-Open No. 58-1195
1. They are a plan view and a sectional view of a main part taken along the line A-A in FIG. 1, showing a conventional escalator for a cross passage shown in Publication No. 78. In the figure, 1 is a main frame arranged in a bridged state, and includes an intermediate frame 1a arranged in a horizontal state, inclined frames 1b and lc arranged on both sides of this intermediate frame 1a, and from this inclined frame. It is composed of flat frames 1d and le placed on both sides. Reference numerals 2 and 3 denote main and driven sprockets provided at both ends of the main frame 1, and 4 a guide rail (not shown) provided along the main frame 1, with a hook passing between the sprockets 2 and 3. A chino 5 guided by the chino 4 is a step connected to the chino 4 and arranged in parallel, and is guided along a guide rail (not shown) provided along the main frame 1. 5a, 5
Reference numeral b denotes a handrail provided along both sides of a moving path made up of parallel treads 5, and the uppermost part of which is provided with a moving path made up of an endless belt that rotates in synchronization with the moving path. Handrail 7a.

7b is provided.

FIG. 11 is an enlarged side view of the step 5 shown in FIGS. 9 and 10. In the figure, the step 5 includes a step portion 5a and a support portion 5.
b, and the step portion 5a is composed of a tread portion 5C.
and risers 5d and 5e that curve toward the lower inner side from both sides of the tread portion 5C. As shown in FIGS. 12 and 13, which are the left side view and right side view of FIG.
and riser cleat 5g for risers 5d and 5e.
++ It has 5gz. Here, the riser cleat 5g+ provided on the riser 5d is connected to each tread cleat 5.
A riser cleat 5gz located in the middle of [ and provided on the riser 5e is provided so as to be continuous with the tread cleat 5f.

On the other hand, the support part 5b is composed of inverted Y-shaped brackets 5h fixed to both sides of the step part 5a, and a roller 51 provided at the center thereof is provided along the main frame 1. The position of the step 5 is regulated by engaging and moving with a guide rail (not shown). Furthermore, rollers 5j and 5h provided at the ends of the inverted Y-shaped portion of the bracket 5h engage with guide rails (not shown), thereby constantly holding the tread portion 5c in a horizontal state.

[Problem that the invention seeks to solve]

However, in the elevator step with the above configuration, the tread cleat 5f is continuous only with the riser cleat 5gz provided on the riser 5e, and is continuous with the riser cleat 5g+ provided on the riser 5d.
As shown in Fig. 14, the tread cleat 5f during horizontal running is in an intermittent state with respect to the adjacent tread cleat.
It doesn't mesh with 5f.

As a result, a slit-like gap will be created between the tread cleat 5f and the adjacent tread cleat 5f at the front and rear, and there is a risk that objects may fall into this area or objects may become caught in the tread cleat 5f. There is. Further, when the step 5 runs on an inclined part, if the riser cleat 5g2 which is continuous with the tread cleat 5f is located below the riser cleat 5g+ which is not continuous as shown in FIG.
As shown in FIG. 16, a cross-sectional view taken along the line B-B, it is safe because the riser cleat 5g+ meshes with the tread cleat 5f, but as shown in FIG. 17, the relationship between the two is reversed. Then, as shown in FIG. 18, a cross-sectional view along line C-c, the tread cleat 5f and riser cleat 5g are
z do not mesh with each other, which creates a gap in this area, creating an extremely dangerous situation.

[Means to solve the problem]

In order to solve this problem, the elevator step according to the present invention has riser cleats provided on both sides of the tread in the moving direction connected to tread cleats provided on the tread.

[Effect]

When configured in this way, the tread cleat always engages with the riser cleat of the adjacent step, no matter what the mutual relationship with the adjacent step is, so it is ensured that there will be no gaps in that area. This is something that can be prevented and made safe.

[Embodiments of the invention]

FIG. 1 is a side view showing an embodiment of one stage of an elevator according to the present invention, and the same parts as in FIG. 11 are indicated using the same symbols. In the same figure, 5e+ is the riser 5d
As shown in FIG. 2, the riser cleat is provided in correspondence with one tread cleat 5f and is continuous with the corresponding tread cleat 5f.

5ez is a riser cleat provided on the riser 5e, and as shown in FIG. 3, it is provided corresponding to one tread cleat 5'' and is continuous with the corresponding tread cleat 5f.

In other words, the difference between FIGS. 1 to 3 and FIGS. 11 to 13 is that one riser 5d of the steps 5 has a tread cleat 5r.
A riser cleat 5e corresponding to the single jump is provided to make the riser cleat 5e continuous, and a riser cleat se corresponding to the single jump of the tread cleat 5f different from the above is provided on the other riser 5e.
t is provided and made continuous.

When the steps of the elevator configured in this manner are running horizontally, as shown in FIG. 4, the tread cleats 5f are alternately engaged with the tread cleats 5r of the steps 5 located before and after the steps, resulting in an engaged state. Therefore, a slit-like gap does not occur between each step 5. Therefore, even if something is accidentally dropped, the risk of it getting caught between the steps is prevented.

Next, as shown in FIG. 5, if we consider the case where the step 5 moves upward on the slope, a cross-sectional view along line D-D is shown in FIG. Riser cleat 5e of step 5 adjacent to f.

Because they are always engaged, there is no gap at all.

Furthermore, as shown in FIG. 7, if we consider the case where the step 5 moves downward on the slope, the tread cleat also 5f
Since the riser cleat 5ez of the adjacent step 5 always meshes with each other, there is no gap at all.

In addition, when a step moves from rising to horizontal or from descending to horizontal, footwear is likely to get caught due to the relative movement of the step, but in this case, the tread cleat is always in mesh with the riser cleat of the adjacent step. Therefore, in the above state, a scooping effect occurs and lifts the footwear, thereby preventing the risk of the footwear being caught.

In the above embodiment, a case has been described in which the tread creases 5f are alternately connected to the left and right riser cleats 5e+ and 5ez, but the present invention is not limited to this. When the arrangement pitch of the tread cleats 5f is small, the same effect can be obtained even if several tread cleats 5f are alternately connected to the left and right riser cleats 5e and 5ez.

〔Effect of the invention〕

As explained above, the escalator step device according to the present invention divides the tread cleats provided on the tread into two groups in a dispersed state, and divides the first tread cleat group into the riser cleat provided on one riser. Since the second tread cleat group is connected in a straight line with the riser cleat provided on the riser on the other side, the tread cleat is always connected to the riser cleat of the adjacent step in the front and back. They become engaged. As a result, there is no slit-like gap between the front and rear of the step, which has the effect of preventing the risk of objects getting caught.
