A three wheel roller skate (10) that can be better maneuvered than a four wheel roller skate, yet allowing an inexperienced or beginner roller skater (16) to enjoy roller skating. A built-in mechanism has three functions, which are: function 1, to lock all wheels (20), (22) in a stop position; function 2, to unlock all wheels (20), (22) in a free rotation position; and function 3, to prevent the front wheels (22) from rotating backwards in an anti-reverse position.

[ What is claimed is new and desired to be protected by Letters Patent is set forth in the appended claims:] [1.] A three wheel roller skate which comprises:a) a boot having a sole, wherein said boot is worn on a foot of a roller skater;b) a support frame which is a generally U-shaped bracket attached to said sole of said boot in an inverted manner, said U-shaped bracket including:i) a base attached to said sole of said boot;ii) a pair of rear wheels mounted in a rotatable manner to a rear end of said support frame; andiii) a front wheel mounted in a rotatable manner to a front end of said support frame, so that said roller skate can be better maneuvered by the roller skater; andiv) a pair of arms extending downwardly from said base, wherein each axle of said rear wheels is mounted to an exterior surface of one said arm, while an axle of said front wheel is mounted between interior surfaces of said arms;c) means for locking said rear wheels and said front wheel, so as to prevent said rear wheels and said front wheel from rotating, said locking means including:i) each said rear wheel having a plurality of apertures radially positioned on an inner surface about the axle and facing the exterior surface of one said arm;ii) a pair of rear wheel stop levers, in which each said rear wheel stop lever is spring biased hinged to the exterior surface of one said arm, so that each said rear wheel stop lever will normally engage with one said aperture in one said rear wheel;iii) said front wheel having a plurality of bores radially positioned on opposite surfaces about the axle and facing the interior surfaces of said arms; andiv) a pair of front wheel stop levers, in which each said front wheel stop lever is spring biased hinged to the interior surface of one said arm, so that each said front wheel stop lever will normally engage with one said bore in said front wheel.
