For the purposes of presenting a brief and clear description of the present invention, the preferred embodiment will be discussed as used for providing a mobile platform for a child that can be pushed by a guardian in a stroller configuration or used alone in a walker configuration. The figures are intended for representative purposes only and should not be considered to be limiting in any respect.

(7) Referring now to FIG. 1, there is shown a perspective view of an embodiment of the convertible walker and stroller in the stroller configuration. The convertible walker and stroller device 10 can be quickly and easily converted between walker and stroller configurations. The device 10 generally includes a base 11 having a plurality of wheels 20 affixed thereto. A platform 12 is movably connected to the base 11. When the device 10 is in the stroller configuration, as shown in FIG. 1, the platform 12 rests on an upper surface of the base 11. The overall area of the platform 12 is slightly reduced in size compared to the size of the base 11, such that the platform 12 can be effectively supported on the base 11. The wheels 20 are height adjustable as well, such that the entire device 10 can be raised further above the ground when in the stroller configuration, as shown in FIG. 1, and lowered back toward the ground when in the walker configuration, as shown in FIG. 3.

(8) The convertible walker and stroller device 10 includes a seating area 19 that provides support for the occupant when the device 10 is in either the stroller or walker configuration. A lower end of the seating area 19 includes one or more openings 18 for receiving the legs of the user therethrough. In some embodiments, and as shown in FIG. 2, the device 10 includes retractable footrests disposed underneath the platform 12, which can be extended to provide a footrest for occupants when the device 10 is in the stroller configuration, and retracted for storage when the device 10 is in the walker configuration. The seat portion 19 also includes a removable seat cushion 16 that supports the user's bottom and a seat back 17 that provides a back rest for the user. In some embodiments, the seat back 17 includes an additional head cushion 25 for added comfort. Additionally, in some embodiments, the angle of the seat back 17 is adjustable so as to adjust the seat portion 19 for optimal comfort.

(9) The seat cushion 16 can be placed within the seating area 19 to support the occupant in a laying or seating position, and can be removed to allow access the to the leg apertures 18, allowing the occupant to extend their legs toward the ground or rest them on the foot rests. In some embodiments, the seat cushion 16 is adjustably positioned within the seating area 19, such that it can be slid rearwardly to access the leg apertures 18. In other words, the seat cushion 16 can be slid rearwardly under the seat back 17 to allow the occupant to extend their legs through the leg apertures 18 and rest their feet on the footrests if desired. This effectively provides to operational modes for the stroller configuration, wherein the seat cushion 16 can provide a flat surface to sit or lay on when installed, and provide access to the leg apertures to let the feet hang down when the cushion 16 is slid rearwardly.

(10) In the illustrated embodiment, the device 10 further includes a tray 23. The tray 23 can be utilized to support items thereon such that they are easily accessible by the occupant. In the illustrated embodiment, the tray 23 is integral to the platform 12, but may be removably secured to the platform 12 in other embodiments. The tray 23 includes a perimeter lip 24 that helps to retain items on the surface of the tray 23. Further, in the shown embodiment, the tray 23 includes a recessed receptacle 35 that can be utilized to support beverage containers or any other suitable items. In other embodiments, other configurations including additional receptacles or storage areas may be utilized for the tray 23.

(11) The convertible walker and stroller device 10 further includes a handlebar 13 that can be utilized to push or pull the device 10 when it is in the stroller configuration. The handlebar 13 is movable between an extended position for use in the stroller configuration and a retracted position for storage when the device 10 is in the walker configuration, as shown in FIG. 3. To accomplish this, two opposing perpendicular ends 14 of the handlebar 13 each connect to a telescopically adjustable support 15 that extends rearwardly from a rear end 22 of the platform 12. The telescopically adjustable supports 15 allow the handlebar 13 to be positioned at a desired distance from the device 10 for comfort during use, or for storage when not in use. In other embodiments, the supports 15 can be attached to the base 11 rather than the platform 12.

(12) Referring now to FIG. 2, there is shown a perspective view of an embodiment of the convertible walker and stroller detailing the height adjustment mechanism. The height adjustment mechanism allows the device to be moved between walker and stroller configurations. In the illustrated embodiment, the height adjustment mechanism comprises a pair of pivoting connectors 32 each having an upper end connected to the platform 12 and a lower end connected to the base 11. The upper and lower ends of the connectors 32 pivotally and slidably engage a track, and the connectors 32 are pivotally connected at a midpoint 33. The pivoting connectors 32 can collapse downwardly until the platform 12 is supported on the base 11 for use in the stroller configuration. The pivoting connectors 32 can likewise be expanded upwardly to support the platform 12 above the base 11, such that a gap is defined therebetween, allowing the device to be used in the walker configuration. In other embodiments, other height adjustment mechanisms may be utilized to adjust the position of the platform 12 with respect to the base 11, such as linear actuators, gas pistons, or the like.

(13) The base 11 comprises an annular member having an open central area 34. The open central area 34 provides an area for the occupant's legs to move around freely, while the annular member forming the base 11 serves as a bumper to protect the occupant from impacts with other objects while moving around with the device 10 in the walker configuration. Additionally, a footrest 35 is positioned between the platform 11 and the base 12. The footrest 35 may be retractable to a stored position or may be fixedly attached to the device 10. The footrest 35 provides a support surface for the occupant's feet when the occupant's legs extend through the leg apertures of the seating area. In this way, the occupant can either support their feet on the ground within the open central area 23 of the base 11 if using the device 10 as a walker, or support their feet on the footrests 35 if using the device 10 as a stroller with the seat cushion slid rearwardly to allow access to the leg apertures 18.

(14) Referring now to FIG. 3, there is shown a perspective view of an embodiment of the convertible walker and stroller in the walker configuration. When the pivoting connectors 32 are extended and the wheels 20 lowered, the platform 12 is separated from the base 11, allowing the device 10 to be utilized by an occupant 201 as a walker. The tray 23 and receptacle 35 are easily accessible when in the walker configuration, while the base 11 provides a bumper to protect the legs of the occupant. The occupant's legs extend through the one or more leg apertures, such that the occupant's body is surrounded by the remaining area of the lower end of the seating portion, thereby retaining the occupant in an upright position and assisting with standing and walking movements.

(15) Referring now to FIG. 4, there is shown a perspective view of a wheel assembly of an embodiment of the convertible walker and stroller. In the illustrated embodiment, the wheel assemblies 20 are height adjustable via a plurality of removable spacers 44. The wheel assemblies 20 include a pivoting castor 42 having a pair of support arms 43 extending downwardly therefrom. The spacers 44 are removably securable between the support arms 43 and the axle connectors 45 that connect to the axle of the wheel 41. In other embodiments, the wheel assemblies 20 are height adjustable via other mechanisms, such as telescopic support arms, linear actuators, gas pistons, or any other suitable height adjustment mechanism. In this way, both the wheel height and the platform height can be adjusted to effectively combine a walker and stroller into a single reconfigurable device.

(16) It is therefore submitted that the instant invention has been shown and described in what is considered to be the most practical and preferred embodiments. It is recognized, however, that departures may be made within the scope of the invention and that obvious modifications will occur to a person skilled in the art.
