Abstract
A low profile safety floor for electrically powered mobile storage systems includes one or more elongated panels that span the building floor between the system rails. To each end of the panels are mounted a pair of leaf springs and a safety switch. The panels are supported above the rails by means of the leaf springs. When a person steps onto the safety floor, the panel is deflected downwardly so that a safety switch is actuated. Positive stops limit the approach of the panel toward the rails. Switch actuation deenergizes the electric motor drive powering the carriages. To prevent panel sag, the panels are manufactured as wood and steel laminates. To further inhibit sagging, the panels are forced into a permanently upwardly convex shape at manufacture.
