A pair of openings disposed on the platform are adapted to receive a pair of legs of an occupant therethrough. The platform is configured to move between an extended position and a retracted position, wherein the platform contacts an upper side of the base when the platform is in the retracted position, and wherein a gap is defined between the base and the platform when the platform is in the extended position. The device can be selectively switched between walker and stroller configurations, providing multiple ways to transport an infant or small child in a single device. ## Claims ### Claim 1 A convertible walker and stroller device, comprising: a base having a plurality of wheels affixed thereto; a platform movably connected to the base via a height adjustment mechanism; a pair of openings adapted to receive a pair of legs of an occupant therethrough; a seat portion that is removably securable to the platform, wherein the seat portion comprises a seat cushion and a seat back, wherein the seat cushion is removably disposed on the platform, wherein the seat cushion includes a forward portion in front of the seat back that covers the pair of openings and a rearward portion extending rearwardly toward a rear end of the platform such that the rearward portion extends underneath the seat back while contacting a rear portion of the platform, wherein the pair of openings are disposed on a lower portion of the seat portion beneath the seat cushion; wherein the platform is configured to move between an extended position and a retracted position; wherein the platform contacts an upper side of the base when the platform is in the retracted position, and wherein a gap is defined between the base and the platform when the platform is in the extended position. ### Claim 2 (depends on 1) The device of claim 1, wherein the height adjustment mechanism comprises a pair of pivoting connectors each having an upper end connected to the platform and a lower end connected to the base. ### Claim 3 (depends on 2) The device of claim 2, wherein the pivoting connectors extend through a slot on the base. ### Claim 4 (depends on 1) The device of claim 1, wherein the base comprises an annular member defining an open central area. ### Claim 5 (depends on 1) The device of claim 1, wherein the seat back of the seat portion comprises a head cushion affixed thereto. ### Claim 6 (depends on 1) The device of claim 1, further comprising a handle extending rearwardly from a rear end of the platform. ### Claim 7 (depends on 6) The device of claim 6, wherein the handle comprises a handle bar having a pair of perpendicular opposing ends, wherein each opposing end is connected to a telescopically adjustable support arm, such that the handle bar is configured to selectively move between an extended position and a retracted position, wherein each telescopically adjustable support arm contacts a rear side of the seat cushion. ### Claim 8 (depends on 1) The device of claim 1, wherein the platform comprises a tray integral thereto, wherein the tray comprises a raised perimeter lip. ### Claim 9 (depends on 8) The device of claim 8, wherein the tray comprises at least one receptacle thereon. ### Claim 10 A convertible walker and stroller device, comprising: a base having a plurality of wheel assemblies affixed thereto, each wheel assembly comprising a plurality of removable spacers adapted to selectively adjust the height of the base with respect to the plurality of wheel assemblies; a platform movably connected to the base via a height adjustment mechanism; a pair of openings adapted to receive a pair of legs of an occupant therethrough; a seat portion that is removably securable to the platform, wherein the seat portion comprises a seat cushion and a seat back, wherein the seat cushion is removably disposed on the platform, wherein the seat cushion includes a forward portion in front of the seat back that covers the pair of openings and a rearward portion extending rearwardly toward a rear end of the platform such that the rearward portion extends underneath the seat back while contacting a rear portion of the platform, wherein the pair of openings are disposed on a lower portion of the seat portion beneath the seat cushion; wherein the platform is configured to move between an extended position and a retracted position; wherein the platform contacts an upper side of the base when the platform is in the retracted position, and wherein a gap is defined between the base and the platform when the platform is in the extended position. ### Claim 11 (depends on 10) The device of claim 10, wherein the height adjustment mechanism comprises a pair of pivoting connectors each having an upper end connected to the platform and a lower end connected to the base. ### Claim 12 (depends on 11) The device of claim 11, wherein the pivoting connectors extend through a slot on the base. ### Claim 13 (depends on 10) The device of claim 10, wherein the base comprises an annular member defining an open central area. ### Claim 14 (depends on 10) The device of claim 10, wherein the seat back of the seat portion comprises a head cushion affixed thereto. ### Claim 15 (depends on 10) The device of claim 10, further comprising a handle extending rearwardly from a rear end of the platform. ### Claim 16 (depends on 15) The device of claim 15, wherein the handle comprises a handle bar having a pair of perpendicular opposing ends, wherein each opposing end is connected to a telescopically adjustable support arm, such that the handle bar is configured to selectively move between an extended position and a retracted position, wherein each telescopically adjustable support arm contacts a rear side of the seat cushion. ### Claim 17 (depends on 10) The device of claim 10, wherein the platform comprises a tray integral thereto, wherein the tray comprises a raised perimeter lip. ### Claim 18 (depends on 17) The device of claim 17, wherein the tray comprises at least one receptacle thereon.
