DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a new cart 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 carriage assembly 10 generally comprises a cart 12 that has a bottom wall 14, an open top side 16 and a peripheral wall 18 extending upwardly from the bottom wall 14. The peripheral wall 18 has a front side 20, a back side 22, a first lateral side 24 and a second lateral side 26. The cart 12 may contain a plurality of objects 28. The objects 28 may be grocery bags or the like. A handle 30 is attached to the cart 12. Finally, the cart 12 may be a grocery cart or the like.
A rolling apparatus 32 is coupled to the cart 12 and abuts a support surface 34 to facilitate the cart 12 being rolled along the support surface 34. The rolling apparatus 32 is positionable in a deployed position to elevate the cart 12 a maximum distance above the support surface 34. The rolling apparatus 32 is positionable in a retracted position to lower the cart 12 to a minimum distance above the support surface 34. The maximum may be between 2 foot and 3 feet. The minimum distance may be between 6 inches and 1 foot.
The rolling apparatus 32 comprises a pair of supports 36 each coupled to the bottom wall 14. One of the supports 36 is positioned adjacent to the front side 20 and one of the supports 36 is positioned adjacent to the back side 22. The supports 36 each comprises a mount 38 and a pair of lateral legs 40 coupled thereto. The mount 38 has a first end 42, a second end 44, a top side 46 and a bottom side 48. The top side 46 of the mount 38 is coupled to the bottom wall 14 and the mount 38 extends between the first lateral side 24 and the second lateral side 26 of the peripheral wall 18.
Each of the lateral legs 40 has a top end 50, a bottom end 52 and a front side 54. The top ends 50 are each pivotally coupled to the mount 38. Each of the lateral legs 40 is positioned adjacent to one of the first end 42 and the second end 44. The lateral legs 40 extend downwardly from the bottom wall 14 when the rolling apparatus 32 is positioned in the deployed position. The lateral legs 40 may extend along the bottom wall when the rolling apparatus 32 is positioned in the retracted position.
A biasing member 56 is positioned within the mount 38. The biasing member 56 engages the top end 50 of each of the lateral legs 40. The biasing member 56 biases the lateral legs 40 into the deployed position. The biasing member 56 may be a coil spring or the like.
A pair of swiveled wheels 58 is each coupled to one of the bottom ends 52. The swiveled wheels 58 abut the support surface 34 when the lateral legs 40 are positioned in the deployed position. Each of the swiveled wheels 58 rotate about a rotational axis extending through the top 50 and bottom 52 ends of the lateral legs 40. A pair of fixed wheels 60 is each coupled to the front side 54 of one of the lateral legs 40. Each of the fixed wheels 60 are prevented from rotating about the rotational axis. The fixed wheels 60 are positioned between the top end 50 and the bottom end 52. The fixed wheels 60 abut the support surface 34 when the lateral legs 40 are positioned in the retracted position.
A cam 62 is rotatably coupled to the bottom side 48 of the mount 38. The cam 62 is centrally positioned on the bottom side 48. A pair of rods 64 is each coupled to the cam 62. Each of the rods 64 has a distal end 66 with respect to the cam 62 and is oriented such that the distal ends 66 engage the top end 50 of one of the lateral legs 40. The rods 64 releasably retain the lateral legs 40 in the deployed position and the retracted position.
A lock 68 is coupled to the cart 12 and is in mechanical communication with the rolling apparatus 32. The lock 68 releases the rolling apparatus 32 to facilitate positioning the rolling apparatus 32 between the deployed position and the retracted position. The lock 68 comprises a lever 70 movably coupled to the cart 12. The lever 70 is positioned on the handle 30 to be engaged by a user and release the rolling apparatus 32 between the deployed and retracted positions. A pair of cables 72 each extends between the lever 70 and the cam 62 on each of the supports 36. The cables 72 rotate the cams 72 when the lever 70 is engaged. The distal ends 66 of the rods 64 disengage from the lateral legs 40 to facilitate the lateral legs 40 being moved between the deployed position and the locked position.
In use, the cart 12 is filled with the objects 28. The lateral legs 40 are positioned in the retracted position to allow the cart 12 to be positioned within a vehicle 74 or the like. The lateral legs 40 are positioned in the deployed position while the cart 12 is removed from the vehicle 74. The objects 28 are placed within and removed from the vehicle 74 at once rather than individually.
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.
