Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clearance adjuster for a passenger conveyor, and more particularly to a clearance adjuster for adjusting a clearance between a step side portion of an escalator and a skirt guard to an appropriate value.

[0002]

2. Description of the Related Art FIG. 7 shows a conventional escalator. In the figure, reference numeral 1 denotes a main frame of the escalator. A balustrade 3 is erected on both sides of the main frame 1 so as to be erected. An endless moving handrail 4 that circulates in synchronization with the steps 2 is slidably wound on the balustrade 3. It has been turned.

Reference numeral 5 denotes a skirt guard (inner side plate) which is close to the side of the step 2, and the skirt guard 5 is shown in FIGS.
As shown in FIG. 2, the panel is connected from a plurality of divided panels, is vertically supported by a plurality of L-shaped skirt angles 6 on both inner sides of the main frame 1, and is hung and connected to the lower part of the balustrade 3. Between the skirt guard 5 and the left and right side portions of the step 2, gaps α and β are formed over the entire length of the skirt guard 5. The gaps α and β are inspected for elevators of Japanese Industrial Standards and JIS. Criterion A4302, 4.3.2
It is required to be a value within a predetermined range over the entire length of the escalator based on No. 9 of No.

Therefore, the skirt guard 5 is removed together with the skirt angle 6 for each divided panel at the time of inspecting the inside of the main frame 1, and after the inspection of the inside of the main frame 1, the skirt angle 6 at the original position is mounted and supported for each divided panel. And the clearance α between the split panel and the left and right sides of the step 2,
The value of β is adjusted by using and measuring a steel scale or the like so as to maintain a predetermined value, and this adjustment prevents the shoe tips and articles of passengers from being caught between the skirt guard 5 and the side portion of the step 2. However, this operation is repeated over the entire length of the escalator.

[0005]

As described above, the conventional skirt guard 5 is removed together with the skirt angle 6 for each divided panel during the internal inspection of the main frame 1, and after the internal inspection, the skirt angle 6 is again provided for each divided panel. Since it is mounted and supported, the clearances α and β between the skirt guard 5 and the left and right sides of the step 2 must be repeatedly adjusted over the entire length of the escalator by using a steel scale or the like for each divided panel, and measurement adjustment work is required. It was not possible to prevent the complicated repetition of and the deterioration of workability.

The present invention has been made in view of the above, and an object of the present invention is to provide a clearance adjusting tool for a passenger conveyor which can facilitate the assembly and adjustment work of the skirt guard.

[0007]

In the present invention, in order to achieve the above-mentioned object, a skirt angle having a predetermined thickness and supporting a side portion of a step of a passenger conveyor and a skirt guard adjacent to this side portion. It is characterized in that a gap adjusting tool for a passenger conveyor is configured by a flat plate-shaped plate inserted between the plates and a base plate horizontally fixed at a right angle to the plate and supported on the tread surface of the step.

[0008]

According to the present invention, the skirt angle which is positioned by inserting the plate of the gap adjusting tool between the elevation of the temporarily fixed skirt angle and the side of the step is screwed and fixed,
If the skirt guard is mounted and supported on the elevation of the skirt angle after the gap adjuster is pulled out from the gap, appropriate gaps α and β can be formed between the skirt guard and the side of the step.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to an embodiment shown in FIGS. 1 to 3. In the drawings, 7 is a gap adjusting tool according to the present invention, and the gap adjusting tool 7 is as shown in FIG. A plate 70 having a flat plate shape and inserted between the side portion of the step 2 and the upright portion of the skirt angle 6, and a base that is horizontally fixed at a right angle to the central portion of the plate 70 and abuts on the tread surface of the step 2. The plate 70 and the plate 71 are formed in a horizontal T shape, and the plate 70 has a reference thickness t ₁ obtained by adding the thickness of the skirt guard 5 to the gaps α and β between the side portion of the step 2 and the skirt guard 5.

Therefore, in order to secure the gaps α and β between the side portion of the step 2 and the skirt guard 5 after the inside of the main frame 1 is inspected, the side portion of the step 2 and the side portion of the step 2 where the skirt guard 5 is removed are temporarily fixed. 2 and 3 in the lower part of the plate 70 of the clearance adjuster 7 in the clearance between the skirt angle 6 and the vertical surface.
The base plate 71 of the gap adjusting tool 7 is brought into contact with and supported by the tread surface of the step 2 as shown in FIG.

Next, the elevation of the skirt angle 6 is brought into contact with the rear surface of the plate 70, and the plate 7 is attached to the side surface of the step 2.
0, the front side of 0 is pressed, the positioned skirt angle 6 is screwed and fixed to the inner portion of the main frame 1, the gap adjusting tool 7 is lifted out of the gap, and then the skirt guard 5 is attached to the vertical portion of the skirt angle 6. By mounting and supporting, the clearances α and β can be reliably maintained in the clearance between the side portion of the step 2 and the skirt guard 5. However, if this work is performed for every 6 units of skirt angle over the entire length of the escalator, the clearances α and β between the side portion of the step 2 and the skirt guard 5 can be easily and uniformly maintained over the entire length of the escalator. It will be possible.

According to the above structure, the gap adjusting tool 7 inserted between the side portion of the step 2 and the upright portion of the skirt angle 6.
Since the plate 70 having the reference thickness t ₁ of ₁ performs the same function as that of the conventional steel scale, it is not necessary to measure the gaps α and β one by one using the steel scale, and the assembling and adjusting work of the skirt guard 5 can be remarkably facilitated. can do.

Although the plate 7 has the reference thickness t ₁ in the above embodiment, as shown in FIG. 4, the upper portion of the plate 70 may be thin so as to have the suitable adaptation thickness t _2. Good, and as shown in FIG. 5, the upper portion of the plate 70 has a suitable matching thickness t ₂ , and
The uppermost portion of the plate 70 may be thin and stepped so as to have a suitable matching thickness t ₃ . Further, the gap adjusting tool 7
As shown in FIG. 6, it is needless to say that the plate 70 of the gap adjuster 7 may be formed to have an inverted L shape, and the plate 70 may have thicknesses t ₁ , t ₂ and t ₃ .

[0014]

As described above, according to the present invention, a flat plate having a predetermined thickness and inserted between the side portion of the step of the passenger conveyor and the skirt angle supporting the skirt guard adjacent to this side portion. Since the gap adjusting tool is composed of the plate of the shape and the base plate which is horizontally fixed to the plate at right angles and is supported on the tread of the step, the assembling and adjusting work of the skirt guard is significantly facilitated over the entire length of the escalator. There is a special effect that you can.
