A combined sports shoe and roller skate includes a sole having a chamber in which is mounted a collapsible roller assembly, wherein the roller assembly has a seat pivotally connected with linking rods, positioning rods, rear arms, front arms, rollers and torsion spring at two sides and a control mechanism is mounted on the seat and composed of a locking bolt, an axle, a pawl, a torsion spring, a tension spring and a pushbutton, whereby the sports shoe can be converted into a roller skate as desired simply by depressing a pushbutton and the roller skate can be also converted into a sports shoe by collapsing the roller assembly into a chamber at the bottom of the sole.

1. A combination shoe and roller skate comprising:(a) a sole having a cavity formed therein; (b) a roller assembly disposed within said sole cavity, said roller assembly including: (1) a longitudinally extended seat; (2) a pair of positioning arms coupled to opposing sides of said seat, said positioning arms each having formed therein an arcuate groove and a radial hole extending transversely therefrom; (3) a pair of primary arms each pivotally coupled to one said positioning arm at a first pivot axis, each said primary arm being pivotally displaceable about said first pivot axis between first and second positions relative to said positioning arm, each said primary arm having formed peripherally thereon at least first and second notches spaced one from the other, each said primary arm being coupled to a laterally extending primary guide pin, said primary guide pin displaceably engaging said arcuate groove of at least one said positioning arm; (4) a pair of secondary arms each pivotally coupled to one said positioning arm at a second pivot axis, each said secondary arm being pivotally displaceable about said second pivot axis between first and second positions relative to said positioning arm, each said secondary arm being coupled to a laterally extending secondary guide pin; and, (5) at least one linking rod extending between said primary and secondary guide pins for linking the pivotal displacements of said primary and secondary arms; and, (c) a control mechanism coupled to said roller assembly for alternatively setting said roller assembly in stowed and extended configurations, said control mechanism including: (1) a locking member pivotally coupled to said seat, said locking member being spring biased to lockingly engage said first notch of at least one said primary arm when said primary arm is in said first position and to lockingly engage said second notch when said primary arm is in said second position; and, (2) an actuation member displaceably coupled to said seat for actuating said locking member, said actuation member being displaceable between first and second control positions; said locking member being alternatively engaged with and disengaged from said primary arm notches responsive to said control position selected for said actuation member.
