Abstract

A safety walker having a frame with a set of spherical caster wheels connected to the lower portion of the frame to provide omnidirectional movement with reduced force. A braking system is provided, where when a weight exceeding a threshold weight is applied to the frame, the brake is engaged to inhibit movement of the walker on the ground. The brake may use a mechanism in which each spherical caster wheel is retractably mounted within a lower end of a corresponding leg of the frame. Each spherical wheel is spring-loaded to urge the spherical wheel downward from the lower end of the corresponding leg. As weight is applied to the frame, the spherical caster wheel is pushed into the lower end of the leg, allowing the lower end of the leg to contact the ground surface and maintain stationary contact between the leg and the ground surface.
