DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a new seat device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 6, the car seat assembly 10 generally comprises a first base 12. The first base 12 comprises an exterior edge 14 extending between each of a top side 16 and a bottom side 18 of the first base 12. The top side 16 of the first base 12 curves upwardly and inwardly. Thus, each of a front side 20 and a rear side 22 of the exterior edge 14 are directed toward a center 24 of the first base 12 to define a pair of wheel wells 26. Each of the wheel wells 26 extends between a first lateral side 28 and a second lateral side 30 of the exterior edge 14. Each of the front side 20 and the rear side 22 of the exterior edge 14 has a respective cut out 32 extending toward an associated one of the wheel wells 26. Each of the cut outs 32 defines a respective pair of lobes 34 on each of the wheel wells 26.
The first base 12 is removably coupled to a vehicle seat 36 such that the bottom side 18 of the first base 12 abuts the vehicle seat 36. The first base 12 has a pair of belt wells 38 each extending inwardly on an associated one of the first lateral side 28 and the second lateral side 30 of the exterior edge 14. A pair of belts 40 is coupled to the first base 12. Each of the belts 40 extends outwardly from an associated one of the belt wells 38. Each of the belts 40 engages the vehicle seat 36 to retain the first base 12 on the vehicle seat 36.
The first base 12 has a pair of grooves 42 each extending into the top side 16 of the first base 12. Each of the grooves 42 is positioned on an upper side 44 of an associated one of the wheel wells 26. Additionally, each of the grooves 42 extends between the first lateral side 28 and the second lateral side 30 of the exterior edge 14. A first set of locks 46 and a second set of locks 48 are each movably coupled to and extend upwardly from the top side 16 of the first base 12. Each of the first set of locks 46 and the second sets of locks 48 are positioned on a respective lower side 50 of an associated one of the wheel wells 26.
A seat 52 is provided. The seat 52 supports an child 54. The seat 52 may be a child car seat or the like. A handle 56 is movably coupled between each of a first oblique side 58 and a second oblique side 60 of the seat 52. The handle 56 may be gripped to manipulate the seat 52.
A second base 62 is provided. The second base 62 has an outermost edge 64 extending between a topmost side 66 and a bottommost side 68 of the second base 62. The topmost side 66 has a seat well 70 extending downwardly therein. A lowermost side 72 of the seat 52 is positionable in the seat well 70 such that the seat 52 is removably coupled to the second base 62.
A pair of legs 74 is provided. Each of the legs 74 comprises a respective pair of first arms 76 each slidably coupled to a respective pair of second arms 78. Thus, each of the legs 74 is structured to form a scissor such that each of the legs 74 is positionable between an extended position and a retracted position. A coupled end 80 of each of the respective first arms 76 is hingedly coupled to the bottommost side 68 of the second base 62. The coupled end 80 of the respective first arms 76 is each positioned proximate an associated one of four corners 82 of the second base 62.
Each of a plurality of wheels 84 is rotatably coupled to an associated free end 86 of each of the respective second arms 78. Each of the wheels 84 slidably engages a respective one of the wheel wells 26. Thus, the second base 62 is urged laterally with respect to the first base 12 to couple and uncouple the second base 62 and the first base 12. Each of the wheels 84 abuts a support surface 88 such that the second base 62 and the seat 52 may be rolled along the support surface 88 after the second base 62 is uncoupled from the first base 12.
The outermost edge 64 of the second base 62 has a plurality of wheel slots 90 extending inwardly therein. Each of the wheel slots 90 is positioned adjacent to an associated one of the four corners 82 of the second base 62. Each of the wheels 84 is positioned within an associated one of the wheel slots 90 when each of the legs 74 is positioned in the retracted position.
The second base 62 has a plurality of tabs 92 coupled to and extending upwardly from the topmost side 66 of the second base 62. Each of the tabs 92 is positioned proximate an associated one of the four corners 82 of the second base 62. Moreover, each of the tabs 92 slidably engages an associated one of the grooves 42. Thus, the second base 62 is maintained in alignment with the first base 12 when the second base 62 is coupled to the first base 12. Each of the first set of locks 46 and the second set of locks 48 engages the bottommost side 68 of the second base 62. Consequently, the second base 62 is retained on the first base 12 when the second base 62 is coupled to the first base 12.
A release button 94 is movably coupled to the first lateral side 28 of the exterior edge 14 of the first base 12. The release button 94 is mechanically coupled to each of the first set of locks 46 and the second set of locks 48. The release button 94 is engaged to release each of the first set of locks 46 and the second set of locks 48 from the second base 62 such that the second base 62 may be uncoupled from the first base 12.
In use, the second base 62 is coupled to the first base 12 when the seat 52 is to be coupled to the vehicle seat 36. The second base 62 is urged laterally rather than being urged vertically when the second base 62 is coupled and uncoupled from the first base 12. Consequently, the second base 62 is removable from the first base 12 without needing to be lifted. Each of the legs 74 are positioned in the extended position so the second base 62 is utilized as a cart. The handle 56 is gripped to push the second base 62 and the seat 52 along the support surface 88.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
