Abstract
A stretcher comprised of a roller base, a scissor-type lift frame having a lower end rotatably connected to the base, a tubular undercarriage rotatably and slidably connected to an upper end of the frame, a foldable rigid support positionable over the undercarriage, a soft, foldable cushion positionable over the support and connected thereto to prevent disassociation therefrom, and first and second side-arm supports rotatably connected to the undercarriage. The undercarriage includes first and second longitudinal frame members and first and second movable end extensions. Internal to each of the longitudinal frame members is a releasably locking mechanism to lock the stretcher at a predetermined height. The internal locking mechanism is releasable allowing the stretcher to be vertically adjusted by either one or two thumb triggers, located at one of the movable end extensions.
