However, what is needed is an all-terrain baby walker including a base with one pair of fixed treaded wheels and one pair of interchangeable treaded wheels and a pair of auxiliary alternate skis interchangeable with the interchangeable wheels via insertion rods which engage receptacles in the base. An upper platform is connected to the base by a pair of stacked interconnected mirror image u-shaped support units. A semicircular seat is disposed on the upper platform. A removable canopy is disposed on the upper platform and has adjustable angle relative to the upper platform. A plurality of handles is disposed on the upper platform with one of the handles being a toy securing member.
FIELD OF THE INVENTION
The present invention relates to child operated walkers, and more particularly, to an all-terrain baby walker.
SUMMARY OF THE INVENTION
The general purpose of the present all-terrain baby walker, described subsequently in greater detail, is to provide an all-terrain baby walker which has many novel features that result in an all-terrain baby walker which is not anticipated, rendered obvious, suggested, or even implied by prior art, either alone or in combination thereof.
To accomplish this, the present height adjustable all-terrain baby walker is provided with interchangeable transport members, including wheels and a pair of skis, which permit a child to move along a variety of surfaces. The present device includes a parallelepiped base with a pair of removable treaded first wheels and a pair of interchangeable treaded wheels securably disposed on a bottom side thereof proximal a rear side and front side thereof, respectively, attachable via insertion rods vertically protruding therefrom. The tread on the first and interchangeable wheels allows a child to easily move across various types of terrain, rather than on only smooth surfaces as typically permitted by baby walkers.
A plurality of receptacles, centrally disposed on the bottom side between the pair of first wheels and the pair of interchangeable wheels on each of the right side and the left side, receive the insertion rods. A pair of auxiliary alternate skis, to be used on snowy terrain, is interchangeably disposed on the bottom side as an alternate to the interchangeable treaded wheels. A pair of the insertion rod holders is vertically disposed on an inner side of each ski in a position alignable with the pair of receptacles. A pair of the plurality of insertion rods is disposed on an external side of each insertion rod holder. The insertion rods engage the respective pair of receptacles.
A parallelepiped upper platform is attached to the base via a pair of stacked interconnected mirror image u-shaped support units disposed on each of the right wall and the left wall. Each support unit has a pair of lower external edges centrally disposed within the respective channeled guide and a pair of upper external edges is disposed on the respective right wall and left wall of the upper platform. A channeled guide, disposed on the base inner edge on each of a right side and a left side thereof, has a forward end disposed proximal the respective forward receptacle and a rearward end disposed proximal the respective first wheel. A stop member is disposed within each channeled guide at the rearward end. A height adjustment assembly, disposed on the bottom side of the base, engages the lower external edges of the support units within the channeled guides to raise and lower the upper platform.
A semispherical seat section is centrally disposed through the upper platform and has a pair of leg holes. A back rest is disposed on the upper platform proximal the rearward wall and directly adjacent the seat section. U-shaped handles disposed on the upper platform proximal the forward wall assist a child in supporting himself while standing and can also include attachable toys. A removable canopy is pivotably disposed on the upper platform to protect a child sitting or standing in the seat section from sunlight or to be flipped behind the child to allow full sunlight exposure. A pair of removable bumpers is attachable to the bottom side of the base proximal each of the front side, the left side, and the right side and are interchangeably attachable with the skis.
Thus has been broadly outlined the more important features of the present all-terrain baby walker so that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.
