ABSTRACT:
TECHNICAL FIELD
The present invention pertains to a step of an escalator, which is made to prevent drawing in of clothing, etc. of a passenger when the passenger uses the escalator.
BACKGROUND OF THE INVENTION
As an escalator of prior art, for instance, one that is illustrated in
FIG. 4
is available. It is comprised as follows. Steps
101
are endlessly connected with a chain, which is continuously driven, and convey passengers in a moving step system. On both sides of the steps
101
, hand rails
102
are provided for the safety of the passengers. Below these, skirt guards
103
are installed.
However, as there may be a gap between the moving steps
101
and the skirt guard
103
on this type of escalator, if a passenger on the step
101
is wearing a long skirt, or other clothing, there is a possibility that the hem of this long skirt may fall between the step
101
and the skirt guard
103
, and eventually be drawn in by the moving step
101
and torn off.
DISCLOSURE OF THE INVENTION
The objective of the present invention is to prevent the clothing of a passenger on a moving step from being drawn in by the step.
To realize this objective, according to the present invention, for a step of an escalator having a tread part and a riser part, guard panels are provided on both sides of the tread part in the step conveyance direction.
