Abstract
An escalator system includes a moving step including a plurality of grooves and drivable in a travel direction. A combplate is located at at least a downstream end of the moving step relative to the travel direction at a step-combplate interface. A retraction device is configured to move the combplate along the travel direction from a normal position toward a retracted position when an entrapment of an object is detected at the step-combplate interface.
Claims20
An escalator system, comprising:
- a moving step including a plurality of grooves and drivable in a travel direction;
- a combplate disposed at at least a downstream end of the moving step relative to the travel direction at a step-combplate interface;
- and
- a retraction device configured to move the combplate along the travel direction from a normal position toward a retracted position when an entrapment of an object is detected at the step-combplate interface.

A combplate assembly of an escalator, comprising:
- a combplate partially defining a step-combplate interface of the escalator, the combplate including a plurality of combplate teeth;
- a retraction device configured to move the combplate along a travel direction from a normal position toward a retracted position when an entrapment of an object is detected at the step-combplate interface.
A method of operating an escalator, comprising:
- driving a moving step including a plurality of grooves in a travel direction toward a combplate, the combplate disposed at at least a downstream end of the moving step relative to the travel direction at a step-combplate interface;
- detecting an entrapment at the step-combplate interface;
- and
- activating a retraction device to move the combplate along the travel direction from a normal position toward a retracted position.
