ABSTRACT:
An emergency device is provided to enable a number of people to be transferred between two areas far apart from each other. The device includes a flat relatively stiff plate capable of being rolled up upon itself and susceptible of longitudinal and transverse deformations according to curvilinear profiles, and plate-deforming elements to change the plate from a flat configuration to an operational one including successive transversely oriented hollow portions. The deformation elements can be a waterproof fabric layer joined to the plate sides and provided with tubular ducts extending over the entire length of the plate. Under operating conditions, the plate is unrolled and the tubular ducts are inflated with pressurized fluid to deform the plate according to the successive hollow portions. The upper layer of the fabric can form an emergency slipway for a plurality of people and the lower hollow-shaped plate can provide a slipway for moving articles.
