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.

[ I claim:] [1.] A movable apparatus including a framework that rests on the ground when in a rest position, and a movable system which is provided with wheels in the rest position which rest on the ground when the movable system is operated to move an object; the movable system includes:a movable part rotating about at least one pivot axis which is secured to said framework;at least two wheels each of them being in free rotation about an axis that is fixed to a first end of said movable part;abutment means located at an opposite end of said movable part and rotatable with the movable part for engaging a retaining element of said framework so as to raise the framework when the abutment means is rotated upwardly, said abutment means comprising an engaging portion that contacts the retaining element when the abutment means is rotated upwardly andlever means, integrally formed with and secured to said movable part at a position opposite to the wheels with respect to said pivot axis and including a lever rotatable in a downward arc in response to a force, for rotating the movable part such that, when the lever rotates in the downward arc, said movable part rotates about the at least one axis with the abutment means rotating upwardly to engage said retaining element whereby a force can be applied against the lever to raise said framework with respect to said wheels resting on the ground, and to move said framework and said object to another location by running the wheels on the ground.
