Convertible shoe for walking and for roller-skating, having laterally deployable wheels incorporated in its sole

A convertible shoe designed for walking and for roller-skating in alternation, said shoe comprising a sole in which recesses are provided, roller skate wheels which, for walking, are retracted into a horizontal position inside the recesses in the sole, and, for skating, are deployed under the sole into a vertical position, and a mechanism for actuating the wheels making it possible to cause the wheels to go from one position to the other in alternation by lateral pivoting, wherein:

• in the vertical position for skating, the wheels are disposed on either side of the sole in the manner of a roller skate;
• and
• wherein the mechanism for actuating the wheels comprises:
• two longitudinal rods disposed one on either side of the shoe and fastened to the sole via bearings enabling them to pivot about their own axes, each of these longitudinal rods carrying the wheels that are situated on the same side of the shoe in such a manner as to constrain them to pivot therewith;
• two pivotally-mounted elements placed at the rear of the shoe, each of which is constrained to pivot with a respective one of the longitudinal rods, and is suitable for pivoting between two limit positions, one of which corresponds to the horizontal position of the wheels for walking, and the other of which corresponds to the vertical position of the wheels for skating;
• and
• an angular blocking device for angularly blocking the pivotally-mounted elements, which device, when it is unlocked releases the pivotally-mounted elements and allows them to pivot freely under the effect of gravity or of a force being exerted on the wheels, on the longitudinal rods or on the pivotally-mounted elements, and, when it is locked, blocks the pivotally-mounted elements simultaneously in one of their limit positions.
