    Abstract: Movable device with retractable wheels so as to easily move a bulky or heavy object such as a parasol stand, comprising a framework resting on the ground in the rest position, and a movable system comprising a movable part (18) rotating about a pivot axis (20) which is secured to the framework, two wheels (22) each of which is free to rotate about an axis (24) fixed to a first end of the movable part, an abutment member located at a second end of the movable part, and blocked by the framework when moving upwards, and a lever (16) which is fast with the movable system in an intermediate position between the pivot axis and the end of the abutment member, such that a force applied to the lever makes it possible to raise the framework with respect to the wheels resting on the ground and to move the object towards another location by running the wheels on the ground.
