DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 9 thereof, a new portable shopping cart embodying the principles and concepts of the present invention and generally designated by the reference numeral 2 will be described.
As best illustrated in FIGS. 1 through 9, the portable shopping cart 2 comprises a platform 4 that has two surfaces comprising a top surface 6 and a bottom surface 8. Furthermore, the platform 4 includes two ends comprising a first end 5 and a second end 7, and also has two edges comprising a first edge 13 and a second edge 15. A quartet of wheels 9, 10, 11, 12 are attached to the bottom surface 8 of the platform 4. Two of the wheels 9 and 10 are forward-facing wheels only, while wheels 11 and 12 are preferably caster-style wheels that can swivel about, thereby increasing maneuverability when the shopping cart 2 is in use.
A stand 14 is the main structural support for the shopping cart 2. The stand 14 comprises a base 16, a vertical mount 18, and a telescoping support 20. The vertical mount 18 and telescoping support 20 each have two ends comprising a top end and a bottom end. The base is pivotally attached to the first end 5 of the platform 4 and is supported by two oversized wheels 22 and 24. The bottom end of the vertical mount 18 is fixedly mounted on the base 16, with the bottom end of the telescoping support 20 being insertable into the top end of the vertical mount 18. A spring pin 26 and a spring 28 are used to hold the telescoping support 20 in place, relative to the vertical mount 18, once the telescoping support 20 has been placed at a desired height. The spring pin 26 is externally attached to the telescoping support 20, with the spring 28 being located within the telescoping support 20.
The shopping cart 2 also includes a basket 30 that is attached to the vertical mount 18 portion of the stand 14. The basket 30 is used to store various items, including paperwork, as needed.
A pair of handlebars 32 are attached to the top end of the telescoping support 20, with the pair of handlebars 32 comprising a right handlebar 34 and a left handlebar 36. Each handlebar has a small, cylindrical basket 38 that is attached to it to allow for storage as needed.
An extendible arm 40 is attached to the top end of the telescoping support 20, with the extendible arm 40 comprising a base 42 and a telescoping portion 44. The base 42 is pivotally attached to the top end of the telescoping support 20, with the telescoping portion 44 of the extendible arm 40 being insertable into the base 42 of the extendible arm 40. A plurality of pegs 46 located on both the base 42 and the telescoping portion 44 of the extendible arm 40 can be used strap things around, such as items on string and rope, when shopping using the shopping cart 2. The arm 40 may be constructed in various cross-sectional shapes.
The telescoping portion 44 of the extendible arm 40 has an attachment 48 that includes a central cutout 50. The central cutout 50 can be used to hang things that have string or rope onto the attachment 48 and can also be used to grab onto the attachment 48 to pull and steer the shopping cart 10. An elastic cord 51 is connected to the attachment 48 and has a hook 53 at distal end of the cord 51 for connecting the cord 51 to one of the pegs 46 to ensure that various items hanging on the base 42 or telescoping portion of the extendible arm 40 are securely fastened to the extendible arm 40 to prevent the items from accidentally falling off of the extendible arm 40 and to prevent theft of such items.
The top surface of the platform 4 has wire siding 52 pivotally attached to both the first edge 13 and the second edge 15 to hold groceries and other items on the platform 4. In addition, the second end of the platform 4 has wire siding 52 attached, with a centrally located cutout 54 within the wire siding to allow the platform to be folded up and placed against the stand 14. Before this is done, the wire siding 52 attached to the first edge 13 and the second edge 15 is folded down against the top surface of the platform 4. Then, the platform 4 is folded up and placed against the stand 14. A male lock piece 56, located on the top surface of the platform 4 near the second end of the platform 4 within the cutout 54, is placed into a female insert 58 that is located on the vertical mount 18 of the stand 14. These interlocking pieces will hold the platform 4 in a vertical position against the stand 14 until it is pulled away by an individual.
The stand 14 can have various cross-sectional shapes. These shapes are highlighted in FIG. 6. A spring pin 62 and a spring 64 are used to hold the platform 4 in a horizontal position, relative to the base 16 of the stand 14, once the platform 4 has been lowered and is ready for use.
An alternative embodiment of the shopping cart 2 can include a second, foldable back basket 70 that is used in addition to the platform 4 and wire siding 52 that is already present. Yet another alternative embodiment of the shopping cart 2 can include a pair of stroller attachments 80 and 82 that are attached to separate support mounts 84 and 86, with a stroller 88 capable of being attached to the stroller attachments 80 and 82 through its handles 90 and 92.
As illustrated in FIG. 9, another alternative embodiment of the shopping cart 2 may include a plurality of hangers 94 for hanging items from the extendible arm 40 for convenient removal of the items without the need to remove other items hanging therefrom. Each hanger 94 preferably has curved ends 95 and a head 96 on each of the ends 95 to prevent an item from slipping off of the hanger 94.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, 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 the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention 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 invention.
