Abstract
The present invention relates to a safety board system. The safety board system of the present invention can directly assist the movement of mobility disadvantaged persons crossing the pedestrian crossing, leading to rapid and safe crossing.
Claims9
A pedestrian crossing safety board system that is installed on a pedestrian crossing to assist the movement of mobility disadvantaged persons, the safety board system comprising:
- a pair of lift platforms that are formed on sidewalks on both sides of the pedestrian crossing;
- one or more shuttles that move along a predetermined travel path within a travel area set on the pedestrian crossing to travel back and forth between the pair of lift platforms and transport passengers to the opposite lift platforms;
- a driving device that moves the shuttles;
- and
- a control device that selectively operates the driving device,
- wherein a pair of travel paths are set on the pedestrian crossing to allow bi-directional movement, and both ends of the pair of travel paths are connected to each other by a pair of direction changing units to form a loop structure in which the shuttles circulate.

- a driving device that moves the shuttles;
- and
- a control device that selectively operates the driving device,
- a direction changing device that rotates the shuttle such that a door unit of the shuttle entering the lift platform faces the lift platform and rotates the shuttle such that the door unit of the shuttle exiting the lift platform is parallel to the travel path,
- wherein the direction changing device comprises:
- a pivot axis that is accommodated in an entry end of the shuttle to protrude therefrom;
- and
- a plurality of wheel units that are accommodated in the shuttle at positions different from the pivot axis and protrude along with the pivot axis from the bottom of the shuttle to rotate the shuttle around the pivot axis.
