Ladder pivotally attached to a generally vertically extending surface

摘要

A ladder attached to a generally vertically extending wall or surface which is particularly useful when attached to the side of vehicles which can pivot outwardly to a slight extent at the bottom area thereof in order to increase the climbing inclination to make it easier to climb vertically for emergency personnel under emergency situations and especially when carrying heavy equipment or other necessary emergency apparatus. The ladder configuration is pivotal between a storage position extending generally vertically next to the wall and a deployed position or extended position set at the inclination angle to facilitate climbing thereof. A resilient locking device can secure the ladder in the collapsed position and a pivotally movable scissors assembly controls movement of the lower portion of the ladder between the inclined position and the vertical position.
