Abstract
A walkway or escalator system for the conveyance of standing passenagers comprises a termination plate associated with the travelling surface and a detector device responsive to the sensing of material ingested between the leading edge of the termination plate and travelling surface so as to shut-off the system in the event that ingestion is detected. Alternatively or in addition the system comprises means for detecting a blockage at the discharge end of the travelling surface as may arise of luggage accumulates at that point or if a passenger falls or is trapped. The detector means operates by sensing the presence of relatively stationary objects or passengers at the discharge end and shuts-off the system if blockage is detected.
Claims6
A comb plate arrangement for use with a walkway system comprising a ribbed travelling surface, said comb plate arrangement comprising a comb plate having comb teeth arranged to intermesh with the ribs of the travelling surface, means mounting the plate for pivotal movement about a horizontal axis so that the plate can pivot between a lowered operative position in which the teeth mesh with the ribbed surface and a raised inoperative position, spring means for biasing the plate into its operative position, releasable locking means for retaining the plate in its lowered operative position, means for detecting an upwards force applied to the plate in the event of ingestion of matter beneath the teeth, and control means operative to shut off operation of the travelling surface and to effect release of the locking means in the event that ingestion is detected.
A system for the conveyance of standing passengers comprising means defining a travelling surface of the system, said surface having an exposed section along which passengers move during normal operation of the system, and means for detecting a blockage to movement of passengers at a discharge end of the exposed section of the travelling surface whereby to stop movement of the surface if blockage occurs, said detecting means comprising means for sensing the presence of relatively stationary objects or relatively stationary passengers on said exposed section at said discharge end.
