## Title
Collapsible shopping cart device

## Abstract

The collapsible shopping cart device provides a shopping cart with pivoting telescopic legs. Two spaced apart front legs mount to a pair of spaced apart leg pivots proximal to the basket bottom front. The pivoted legs provide for total collapse to the basket bottom or extension to positions that allow the basket to be selectively varied in height above a given surface such as a store floor. The basket may be provided with hinges between the basket sides and front and back and the basket bottom such that sides, front, and back may collapse for even greater collapsibility for either transport or storage. The sides, front and back are selectively locked in place when expanded. The seat bottom and back may be removable. The handle may be removable. The entire basket and its upwardly disposed components may therefore provide extreme compactability.

## Background
BACKGROUND OF THE INVENTION
Shopping carts are ubiquitous in many stores. Their usefulness is fully established. Shopping carts, though, belong to the various stores that provide them. Carrying a shopping cart in most vehicles, even if user purchased, is either impossible or impractical. Therefore, upon arrival at a final destination, such as home, with purchased goods, transporting those goods from an automobile to a desired location is quite laborious and inconvenient. The present device provides a collapsible cart that can be easily transported, expanded for use at a given store, and collapsed for transport to a final destination. The cart device can then again be expanded for use in conveying items from an automobile.
FIELD OF THE INVENTION
The collapsible shopping cart device relates to shopping carts.
SUMMARY OF THE INVENTION
The general purpose of the collapsible shopping cart device, described subsequently in greater detail, is to provide a collapsible shopping cart device which has many novel features that result in an improved collapsible shopping cart device which is not anticipated, rendered obvious, suggested, or even implied by prior art, either alone or in combination thereof.
To attain this, the collapsible shopping cart device provides a shopping cart with pivoting telescopic legs. Two spaced apart front legs mount to a pair of spaced apart leg pivots proximal to the basket bottom front. The pivoted legs provide for total collapse to the basket bottom or extension to positions that allow the basket to be selectively varied in height above a given surface such as a store floor. The basket may be provided with hinges between the basket sides and front and back and the basket bottom such that sides, front, and back may collapse for even greater collapsibility for either transport or storage. The sides, front and back are selectively locked in place when expanded. The seat bottom and back may be removable. The handle may be removable. The entire basket and its upwardly disposed components may therefore provide extreme compactability.
A further important feature is the pair of spaced apart casters mounted to the basket front bottom. When the front telescopic legs and the angled telescopic legs are folded to the basket bottom, the front casters provide for easy loading and unloading into and out of an automobile.
Thus has been broadly outlined the more important features of the improved collapsible shopping cart device 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.
An object of the collapsible shopping cart device is to provide for use in conveying goods while shopping.
Another object of the collapsible shopping cart device is to provide a collapsible basket for ease of transport.
A further object of the collapsible shopping cart device is to provide a collapsible frame for ease of transport.
An added object of the collapsible shopping cart device is to provide for height adjustability.
And, an object of the collapsible shopping cart device is to provide a removable child seat.
Still another object of the collapsible shopping cart device is to provide a removable handle.
These together with additional objects, features and advantages of the improved collapsible shopping cart device will be readily apparent to those of ordinary skill in the art upon reading the following detailed description of presently preferred, but nonetheless illustrative, embodiments of the improved collapsible shopping cart device when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE DRAWINGS
With reference now to the drawings, and in particular FIGS. 1 through 6 thereof, the principles and concepts of the collapsible shopping cart device generally designated by the reference number 10 will be described.
Referring to FIG. 5, the device 10 partially comprises the collapsible open mesh basket 20.
Referring to FIG. 1, the basket 20 has a top 21 spaced apart from a lipped bottom 22, a front 23 spaced apart from a rear 24, and a first side 25 spaced apart from a second side 26. The leg receipt panel 27 is disposed uppermost in the basket 20 rear 24.
Referring to FIG. 4, a slot 28 is disposed vertically and upwardly within each basket 20 side. Each slot 28 is proximal to the rear 24.
Referring to FIG. 5, a hinge fastens each of the sides, the front 23, and the rear 24 to the basket 20 bottom 22. The bottom 22 is lipped. A plurality of lock pins 30 is provided. One lock pin 30 is disposed upwardly within each basket 20 side adjacent to the front 23. One lock pin 30 is disposed upwardly within each side adjacent to the rear 24.
Referring to FIG. 6, a pair of pin receptacles 31 is disposed upwardly in each of the basket 20 front 23 and rear 24. Each pin receptacle 31 is in removable receipt of one lock pin 30. Referring again to FIG. 4, the removable handle 40 is disposed rearwardly on the leg receipt panel 27 via a pair of spaced apart supports 41. Each support 41 further comprises an upwardly disposed hook tab 42 spaced apart from a downwardly disposed tab 43. The hook tab 42 and tab 43 removably engage the leg receipt panel 27. The removable seat 44 has a seat bottom 45 affixed to a seat back 46 by a pivot 47. The seat bottom 45 is disposed forwardly and perpendicularly from the leg receipt panel 27. The seat back 46 is selectively disposed upwardly and forwardly from the seat bottom 45. The seat back 46 is about parallel to the leg receipt panel 27 when installed in the basket 20.
A support tab 48 is disposed upwardly on each side of the seat back 46. Each support tab 48 slideably and removably fits within a one each of the side slots 28.
Referring to FIG. 2, a pair of spaced apart leg pivots 59 is affixed downwardly on the basket 20 bottom 22 proximal to the front 23.
Referring to FIG. 1, a pair of front telescopic legs 51 is provided. One of each of the front telescopic legs 51 is affixed to one of each of the leg pivots 59. The front cross brace 52 connects the front telescopic legs 51.
Referring again to FIG. 2, a pair of spaced apart angled telescopic legs 54 is affixed to the leg pivots 59.
Referring again to FIG. 1, an angle leg brace 55 connects the angled telescopic legs 54. A caster 56 is disposed downwardly on each leg.
Referring to FIG. 3 and again to FIG. 1, a pair of spaced apart casters 56 is disposed downwardly on the basket 20 bottom 22 adjacent to the front 23. An inwardly bending locking arm 57 connects downwardly to the basket 20 bottom 22 at an arm pivot 58 disposed rearwardly on the bottom 22. The locking arm 57 connects downwardly to one of the angled telescopic legs 54.
Directional terms such as “front”, “back”, “in”, “out”, “downward”, “upper”, “lower”, and the like may have been used in the description. These terms are applicable to the embodiments shown and described in conjunction with the drawings. These terms are merely used for the purpose of description in connection with the drawings and do not necessarily apply to the position in which the collapsible shopping cart device may be used.
