Evacuation chair
摘要:
A chair secured between parallel carrier arms which extend from the front and back of the chair enables the carrying of a handicapped person by two other people including on staircases or under other conditions where conventional conveyances for the handicapped such as wheel chairs, gurneys, stretchers or the like are unsuitable. The chair is extendable and contractable relative to the carrier arms between an expanded operating configuration and a flat compact storage configuration which makes it practical to stock and prominently display the apparatus in locations such as high rise buildings where it may be needed during emergency evacuations or for other purposes.
