Abstract: A stairway chairlift device has a rail incorporating a gear rack, a carriage unit having a motor and gear box which operatively engage the gear rack to provide motion of the chairlift, and a collapsible seat assembly mounted to the carriage unit. The carriage unit also incorporates a battery unit and control circuitry to control operation of the chairlift. The electrical system also incorporates an automatic recharging circuit any time the chairlift is at the bottom or top of the rail. The seat assembly is easily pivoted on a swivel mechanism which permits the seat assembly to be locked in one of three positions--right 90.degree., front or left 90.degree..

Abstract: A motor vehicle having a vertically openable access door includes a reinforcement bracket for each cylinder mounting. The bracket is bent to provide tortional and other force absorption capability. The bracket is also of sufficient size to cover the immediate area where a cylinder is mounted and any remote locations where forces may be applied through a moment arm created by rotation and exertion of a force on the vehicle by a cylinder. The cylinders may be hydraulically operated to effectuate opening and closing of the door.

Abstract: An equipment mounting system includes a fixed leg and a second leg pivotable thereon. Equipment mounted at the free end of the second leg is pivotable to a position which is clear of a motor vehicle access location. When the mounting system is locked in a closed position, the equipment is operable. Further, whenever the mounting system is not locked in a closed position, one or more disabling devices prohibit operation of the equipment.

Abstract: An adjustable support base for portable vehicle mounted equipment includes a perpendicular pair of support legs adjustable relative to one another. Each leg is adjustable in length and anchorable to the vehicle on which the equipment is being mounted. A plate mounting system is angularly adjustable and secures the vehicle mounted equipment to the base provided by the support legs.
