Abstract
The present invention relates to a mechanically expandable and collapsible traffic warning device safety marker comprising a base member, a controllable linear motion machine assembly and a battery with its connecting components which are contained within the base member, a collapsible body member, and an actuator switch member. The controllable linear motion machine assembly is controlled by an actuator switch member that enables the collapsible body member to mechanically collapse and expand upon user interaction. The controllable linear motion machine assembly mechanically retracts the collapsible body member to a nested position within the base member for compaction upon the user pressing the actuator switch member resulting in the mechanically expandable and collapsible traffic warning device safety marker to be easily stored within a compartment of a vehicle and mechanically expanding the expandable and collapsible body member conveniently to a ready for application condition.
