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 lift frame includes left and right side assemblies, each side assembly having a fixed-length leg member and a telescoping variable-length leg member, both of which are rotatably connected to the base, and rotatably and/or slidably connected to the undercarriage. The leg members of each side assembly are connected to one another at their respective mid-sections by a joint, and are rotatable with respect to one another along an axis of the joint, which is offset from the member's central axes. 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.

1. An emergency stretcher, comprising:a vertically adjustable wheeled undercarriage having opposed first and second longitudinal frame members each having a proximate end, said undercarriage includes a first movable end extension rotatably mounted at said proximate end of each said longitudinal support members, said first movable end extension being positionable in at least two positions; an articulatable patient support provided on said undercarriage; a securing device mounted to said undercarriage to releasably arrest vertical movement of said patient support by said undercarriage; and at least one release flipper mounted to said first movable end extension and operationally connected to said securing device such that depressing said at least one release flipper will release said securing device in said at least two positions, thereby permitting said vertical movement of said patient support by said undercarriage.
