A skirt guard switch that operates when a pressing force is applied to the skirt guard exceeding a predetermined value is provided.

Conventionally, as a measure of the operating force of the skirt guard switch, a fixed base is engaged with a groove of a step, and a presser of a spring scale is pressed against the skirt guard by a lever supported by the fixed base. By applying one end of a lever supporting the spring or the pressing element to the groove of the step and applying a force to the other end of the lever using this as a fulcrum, a pressing force is applied to the skirt guard. Something like that has been proposed.

Examples of this type include those described in JP-A-58-47785, JP-A-60-161889 and JP-A-6-278983.

[0005]

By the way, in the above-mentioned prior art, the reaction force of the force applied to the skirt guard is received in steps, and a load is applied to the groove of this step. For this reason, if the number of grooves for engaging the device is reduced, that is, if the engagement area is reduced, the protrusion between the grooves may be deformed, while the number of engagement grooves is increased, that is, the engagement area is increased. Then, there was a problem that the device became large and bulky. In particular, in the case of using the same steps as the escalator as in the case of the auto line, the operating force of the skirt guard switch is large, that is, in the case where a large force needs to be applied to the skirt guard, Since the reaction force is large, there is a high possibility that the protrusion between the grooves is deformed.

The present invention has been made in view of such a situation in the prior art, and a first object of the present invention is to reduce the operating force of the skirt guard without having to receive the reaction force of the force applied to the skirt guard in steps. It is an object of the present invention to provide an apparatus for measuring a skirt guard switch operating force of a passenger conveyor capable of performing a measurement.

Operating force of a skirt guard switch, which is disposed on the opposite side of the skirt guard from the step and is operated when a pressing force exceeds a predetermined value on the skirt guard. In the skirt guard switch operating force measuring device of the passenger conveyor for measuring the measurement device, one end abuts on the step side of one skirt guard, one end abuts on the step side of the other skirt guard, and the other end A pressing force applying means for contacting the other end of the measuring tool is provided.

According to the first aspect of the present invention configured as described above, one end of the measuring tool is brought into contact with the step side of one skirt guard, and one end of the pressing force applying means is connected to the other of the skirt guard. The pressing means is brought into contact with the step side of the skirt guard, and the other end of the pressing force applying means is brought into contact with the other end of the measuring tool. In this state, a pressing force is applied to the skirt guard by the pressing force applying means to operate the skirt guard switch, and the operating force at this time is measured by the measuring tool. As described above, since the force applied by the pressing force applying means acts on each skirt guard, it is not necessary to receive the reaction force of the force applied to the skirt guard in steps, so that the measurement of the operating force can be performed. It can be carried out.

In order to achieve the second object, the invention according to claim 2 of the present invention is characterized in that the pressing force applying means is provided with a pressing element which abuts a step side of the skirt guard and has a threaded rod. And a pressing body which is screwed with the screw bar, moves in accordance with the rotation, and presses the measuring tool.

According to the second aspect of the present invention, the pressing member is brought into contact with the step side of the skirt guard, and the pressing member screwed with the screw rod of the pressing member is rotated. When the skirt guard switch is moved, the skirt guard switch is operated by applying a pressing force to the skirt guard in correlation with the pressing of the measuring tool. In this way, it is possible to apply a pressing force to the skirt guard in a simple manner using a screw,
The device can have a simple structure.
