MOVING DEVICE WHICH IS AUTOMATIC TRAVEL FLOOR CLEANER

摘要

PROBLEM TO BE SOLVED: To provide a moving device having a low cost mechanism for getting over obstacles.SOLUTION: A moving device 1 which is an automatic travel floor device comprises a chassis 2 and plural wheels 3 at least one of which can be driven. The plural wheels 3 are attached to the chassis 2 via a suspension component 5 which is movable to the chassis 2. The wheels 3 are disposed so as to be supported under action of a spring 7 by application of spring force on a floor where the moving device 1 can travel, and the plural wheels 3 can retreat or protrude to the chassis 2 by assistance of the suspension component 5. The spring force can be changed freely regardless of increase or decrease of spring force generated by retreat or protrusion of the wheels 3, and can be changed freely to become large as a protrusion amount of the wheels 3 becomes large.SELECTED DRAWING: Figure 3
