Abstract
A monitored escalator barricade system is disclosed herein having a barricade assembly including a hosting column supporting a one-way swinging door and a magnetic locking mechanism. The barricade assembly is installable at a landing floor and allows for one-way passage of a user riding along an outer edge of an escalator in order to prevent injuries. The barricade assembly utilizes IR beam transmitters on an exterior of the hosting column to detect when a user arrives near the landing floor and unlock the one-way swinging door as the user approaches. The monitored escalator barricade system includes various visual and audio indicators for notifying authorities.
Claims20
A monitored escalator barricade system, the monitored escalator barricade system comprising:
- a barricade assembly which is installable on a landing floor proximal to an escalator including;
- a one-way swinging door allowing one-way passage of a user having a magnetized metal door-plate on an open vertical plane of the one-way swinging door;
- a hosting column supporting the one-way swinging door and housing a transceiver and including infrared (IR) beam transmitters on an exterior of the hosting column configured to detect when the user arrives near the landing floor;
- a magnetized metal floor tab in alignment to and magnetically contacts to the magnetized metal door-plate;
- and
- an alarm system in communication with the transceiver and configured to activate when the one-way swinging door is pushed by the user and to notify authorities;
- and
- wherein the transceiver is electrically connected to the magnetized metal door-plate and the IR beam transmitters are electrically connected by wire to the transceiver;
- and
- wherein the hosting column is supported upon a base plate, the base plate being mountable to the landing floor.
