Abstract
A safety floor construction comprising plural floor sections suspended on springs such that each floor section is depressed whenever a person stands on that floor section while in an aisle between carriages. One or more safety switches are mounted on each carriage. The switch actuators engage the floor sections. When a floor section is depressed by a user, the switch is actuated and interrupts the motor drive circuit for the carriages. Thus, the adjacent carriages cannot move. The movable floor is constituted of individual reinforced plywood panels provided at their edges with metal which are contacted by the spring supports. Moreover, the floor panel spring supports are mounted under the rail attached to the sub floor and require no attachment to the panel.
