Abstract: A collapsible hydraulically operated ambulance cot having a support frame, a wheeled base, a support mechanism disposed therebetween, and a lift system for hydraulically moving the upper frame relative to the lower frame is disclosed. The lift system permits a single attendant to raise the cot from a lowered position to a raised position, and an infinite number of positions therebetween, and to raise the wheeled base relative to the support frame to situate the cot onto an elevated surface such as the transport deck of an ambulance. A manual override is also provided to conserve battery power and as a back-up in no-power situations. It is to be appreciated that the above described manual override mode may be used when raising or lowering the cot without power assist, dropping the undercarriage when unloading from a vehicle, and lifting the undercarriage when loading into a vehicle.

Abstract: A roll-in cot (1) having a patient support attached to a wheeled transporter wherein the wheeled transporter comprises leading (3) and trailing (4) collapsible legs having respective proximal ends pivotally connected to a frame (2) and distal ends including swivel castor wheels (18A, 18B) wherein at least the swivel castors (18A) of the leading collapsible legs (3) are operable in either a swivel or lock mode, and wherein the swivel mode is only operable by a castor release mechanism (22) while the cot (1) is in a fully upright position.

Abstract: A collapsible hydraulically operated ambulance cot (2) having a support frame, a wheeled base, a support mechanism (16) disposed therebetween, and a lift system (10) for hydraulically moving the upper (12) frame relative to the lower frame (14) is disclosed. The lift system (10) permits a single attendant to raise the cot (2) from a lowered position to a raised position, and an infinite number of positions therebetween, and to raise the wheeled base relative to the support frame to situate the cot onto an elevated surface such as the transport deck of an ambulance. A manual override is also provided to conserve battery (30) power and as a back-up in no-power situations. It is to be appreciated that the above described manual override mode may be used when raising or lowering the cot (2) without power assist, dropping the undercarriage (11) when unloading from a vehicle, and lifting the undercarriage (11) when loading into a vehicle.

Abstract: A collapsible pneumatically operated ambulance cot having a support frame, a wheeled base, a support mechanism disposed therebetween, and a lift mechanism for pneumatically moving the upper frame relative to the lower frame is disclosed. The lift mechanism permits a single attendant to raise the cot from a lowered position to a raised position, and an infinite number of positions therebetween, and to raise the wheeled base relative to the support frame to situate the cot onto an elevated surface such as the transport deck of an ambulance.

Abstract: A multiple level elevating cot adapted to be rolled into emergency vehicles, the cot having a wheeled undercarriage supporting a cot frame having a leading end and a trailing end, and adapted to selectively secure the cot frame in a plurality of elevational positions. The cot frame includes a pair of side extension arms provided between the leading end and the trailing end, each of the side extension arms being adapted to slidably extend outwardly from a stowed position adjacent the cot frame to an extended position substantially perpendicular to the cot frame. The cot frame may form a part of an integral stretcher or may serve as a carrier to which a separable top structure, such as a stretcher/stair chair, may be detachably secured, the cot frame including seats for slidably receiving the top structure and latching means for securing the top structure to the cot frame.
