Abstract
A powered gap mitigation device for transit vehicles allows a gap mitigation plate to move outboard from its stowed position, be locked in the deployed position, move inboard from a deployed position to a stowed position, be locked in the stowed position, and be manually stowed and cut-out in case of malfunction.
Claims19
A low profile powered gap mitigation device for transit vehicles allowing a gap mitigation plate through a clutch linkage driven by a motor to move back and forth between a stowed position and a deployed position and to be locked in either position, wherein the device comprises:
- a cutout mechanism operated entirely manually which:
- a) in a normal position engages the clutch with the motor to move the plate;
- b) in a neutral position disengages the clutch from the motor;
- and
- c) in a cutout position disengages the clutch from the motor and locks the plate in the stowed position.
In a low profile powered gap mitigation device for transit vehicles allowing a gap mitigation plate through a clutch linkage driven by a motor to move back and forth between a stowed position and a deployed position and to be locked in either position, a method for introducing three positions of the plate using a single cutout mechanism comprising the steps of:
- a) manually moving a lever to a normal position to engage the clutch with the motor to move the plate;
- b) manually moving the same lever to a neutral position to disengage the clutch from the motor;
- and
- c) manually moving the same lever to a cutout position to disengage the clutch from the motor and at the same time activate a first locking mechanism to lock the plate in the stowed position.
