Title:
CONVEYOR PERSONNEL GATE
Document Type and Number:
WIPO Patent Application WO2002040388
Kind Code:
A3
Abstract:
A freestanding conveyor personnel gate includes a support or base portion and a conveyor portion, which is pivotable and movable relative to the support between a closed position and an open position. The gate includes a latch mechanism which is operable to latch the gate in both the open and close positions. The latch mechanism is operable via a handle which is movable in either direction to disengage the latch mechanism and to raise or lower the conveyor portion toward its open or closed position. The conveyor portion is balanced and supported via a strut member which is pivotally mounted at the conveyor portion and the support portion. A biasing member is provided to bias the conveyor portion toward its closed position when the conveyor portion is moved past a neutral point between the open and close position. The biasing member is further operable to bias the conveyor portion toward its opened position when the conveyor portion is moved past the neutral position toward the open position of the gate. The biasing member thus self propels the gate toward its opened or closed position, while the latch mechanism locks the gate in the respective position once that position is reached by the conveyor portion.
