  • Patent number: 7699324
    Abstract: A lightweight, strong, sturdy, and versatile evacuation sled is disclosed. The body of the sled may be manufactured from a single piece of material, stored flat, and folded into its functioning configuration. When folded, the sled has one or more straps that help hold it in its folded configuration and allow maneuvering or carrying the sled. The sled may be readily towed with a towing harness and may be moved down an incline, such as stairs, by means of a rope and belay device. The sled has a low coefficient of friction and is lightweight, allowing the sled to be readily moved and handled without requiring the assistance of multiple people. Additional sleds with foam inserts may be provided to carry equipment such as for life support. The sled may also provide surge capacity for facilities like hospitals, as the sled is designed to be inexpensive and essentially disposable.
