Abstract

PROBLEM TO BE SOLVED: To make a pressing part of a tension gauge so as not to slide on the surface of a skirt guard plate even if forcibly pressing this tension gauge toward the skirt guard plate surface. SOLUTION: An antislipper 12, preventing a forcily pressing part 11a from sliding on a skirt guard plate 4 at a time when this pressing part 11a is forcibly pressed to this plate 4, is installed in the forcibly pressing part 11a to the skirt guard plate 4 of a tension gauge 11.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skirt guard for a passenger conveyor in which the pressing force when the skirt guard plate of the passenger conveyor is pressed to the back side to operate the skirt guard switch is measured by a tension gauge. The present invention relates to a switch operating force measurement device.

[0002]

2. Description of the Related Art Conventionally, an operating force measuring device for a skirt guard switch operates the skirt guard switch by bending the skirt guard plate by pressing the surface of the skirt guard plate with a pressing portion of a tension gauge. The pressing force of the skirt guard plate was read with a tension gauge.

However, since a lubricant or the like is applied to the surface of the skirt guard plate, when the surface of the skirt guard plate is pressed by the pressing portion of the tension gauge, the pressing portion slips on the surface of the skirt guard plate, The surface portion of the skirt guard plate facing the skirt guard switch cannot be pushed accurately and easily.

[0004]

In the above-mentioned prior art, when the pressing portion of the tension gauge deviates from the surface portion of the skirt guard plate facing the skirt guard switch, the value of the pressing force read by the tension gauge is changed. There is a problem that it will vary widely,
Since it is necessary to press the tension gauge against the skirt guard plate with a force of 10 kg or more in a narrow space on the step of the passenger conveyor, there is a problem that if the tension gauge slides on the surface of the skirt guard plate, it will be a very dangerous work. .

In view of the above problems, an object of the present invention is to provide
Another object of the present invention is to provide an operating force measuring device for a skirt guard switch in a passenger conveyor in which the tension gauge does not slip on the skirt guard plate surface even when the tension gauge is pressed against the skirt guard plate surface.

[0006]

The above-mentioned object is to provide a large number of steps connected endlessly, a skirt guard plate standing upright along the ends of these steps, and a skirt guard plate provided on the back side of the skirt guard plate. A passenger conveyor comprising at least a skirt guard switch, wherein a tension gauge for operating the skirt guard switch by pressing against the back side of the skirt guard of the passenger conveyor is provided, and when the skirt guard switch is operated by the tension gauge. In an operating force measuring device for a skirt guard switch in a passenger conveyor configured to measure a pressing force on the skirt guard plate, the pressing part of the tension gauge on the skirt guard plate is provided with the pressing part. When pressed against the skirt guard plate By providing a non-slip material to prevent the slipping is achieved.

[0007]

With this structure, even if the pressing portion of the tension gauge is pressed against the surface of the skirt guard plate, the non-slip body prevents the pressing portion of the tension gauge from slipping on the surface of the skirt guard plate, and the skirt guard switch. The surface portion of the skirt guard plate opposite to is accurately and easily pressed by the pressing portion of the tension gauge to bend and actuate the skirt guard switch.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1, an escalator 1 comprises a frame 2, a number of steps 3 arranged on the frame 2 and connected endlessly, and skirt guard plates standing on both sides of the step 3. 4, a panel 6 that supports the handrail 5, and an inner deck cover 7 that closes the space between the panel 6 and the skirt guard plate 4.

The skirt guard switch 8 is a frame 2
Is fixed to the bracket via a bracket 9. When a foreign object is sandwiched between the steps 3 and the skirt guard plate 4, the skirt guard switch 8 operates when the skirt guard plate 4 bends, and the escalator 1 stops. On the surface of the skirt guard plate 4, a patch 10 labeled SGS is attached. Patch 10
Is attached to the skirt guard plate 4 at a position facing the operating portion 8a of the skirt guard switch 8.

The non-slip body 12 formed of a suction cup or the like provided on the pressing portion 11a of the tension gauge 11 is attached to the patch 10
After abutting against the skirt guard plate 4 located outside of the skirt guard plate 4 as shown in FIG. 3, the tension gauge 11 is pressed toward the skirt guard plate 4 so that the skirt guard plate 7 is bent and the skirt guard switch 8 The operator visually reads the value of the pressing force displayed on the scale portion 11b of the tension gauge 11 when activating. in this case,
Even if the tension gauge 11 is pressed against the skirt guard plate 7, the non-slip body 12 prevents the tension gauge 11 from slipping on the surface of the skirt guard plate 7 and causes the pressing portion 11a of the tension gauge 11 to move to the skirt guard switch 8. Since the anti-slip bodies 12 can be easily installed at the opposite positions, the work of measuring the operating force of the skirt guard switch 8 can be performed accurately and safely.

[0012]

As described above, according to the present invention, the operating force of the skirt guard switch can be accurately and easily measured, and the operating force can be measured safely. it can.
