## Background
BACKGROUND OF THE INVENTION
The present invention relates to shopping carts and more particularly to a shopping cart modified for vehicle transport and advertising method comprising a shopping cart modified to be lifted and carried behind a vehicle with advertising placards on the side walls, front wall and rear wall thereof whereby to carry promotional material which is visible to a user person and other shoppers and the advertising method wherein the promotional material generates additional income to a owner of the shopping cart by increasing sales and providing a payback of the shopping cart.
DESCRIPTION OF THE PRIOR ART
It is well known that shopping carts, of the kind typically found in supermarkets, department stores or other such stores are characterized by their use wherein the groceries, or other goods, are selected and placed in the shopping cart for transport to a check out station. The groceries are then unloaded onto a check-out counter. After scanning, or otherwise paying for the groceries, the groceries are again loaded back into the shopping cart. The shopping cart is moved to the vehicle wherein the groceries are once again unloaded and placed in the vehicle. After arriving at the final destination the groceries are removed from the vehicle and transported into the location of eventual use after sometimes making multiple trips back and forth to the vehicle. This requires the groceries to be handled multiple times which is inefficient and a burden especially to the elderly or those with infirmities.
These conventional type shopping carts have never been sold or marketed to individual shoppers because there was not a way to transport conventional shopping carts in the past by automotive vehicles. With a shopping cart modified for vehicle transport and advertising method, a shopper can use a personal conventional type shopping cart for their grocery shopping and in so doing can enjoy a much easier grocery shopping trip, eliminating multiple transfers of groceries that occur today with an average grocery shopping trip.
The shopping cart modified for vehicle transport and advertising method of this invention provides a ready means for the individual homeowner to easily accomplish the grocery shopping. The shopper is always assured of a shopping cart for use during his shopping venture. Moreover, the shopping cart modified for vehicle transport and advertising method offers a further advantage in that during inclement weather, the shopper is not bothered with transferring bags of groceries from a shopping cart to his automobile but can merely place the shopping cart on the carrier means with the groceries therein for transport to his residence. This is done simply and with little effort. At the destination end, the shopping cart is removed from the carrier and taken directly into the house or apartment for removal of the groceries in the kitchen or wherever else desired. The shopping cart can then be stored in a desirable area until it is needed once again for shopping.
Ownership by individuals of shopping carts in accordance with this invention is, moreover, extremely advantageous to the store owner now maintaining a rather large inventory of shopping carts. Costs of operations to the store owner will be somewhat reduced as the inventory of carts needed by the store or market can be reduced as time goes on. As the shopping carts are owned by the individual shoppers, these shopping carts will not become abandoned eyesores on city streets and sidewalks or in the parking lots of stores to become a nuisance to drivers.
The use of shopping carts is known in the prior art. More specifically, shopping carts of known designs and configurations previously devised and utilized for the purpose of holding and storing purchases through conventional methods and apparatuses are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.
By way of example,
U.S. Pat. No. 5,548,911 to Myers relates to an improved shopping cart with a pair of large plates affixed to one another with one plate on each side of the front wall of the shopping cart basket.
U.S. Pat. No. 5,794,953 to Duchene, et al. relates to an improved shopping cart with advertising card mount to plastic basket.
U.S. Pat. No. 5,235,767 to Waterman, et al. relates to a Shopping cart with a display unit that includes an enlarged platelike base member.
U.S. Pat. No. 6,641,147 to Werner relates to a modified shopping cart for holding large, long and bulky items, such as building materials and the like.
U.S. Pat. No. 5,280,932 to Folsom relates to a shopping cart with a waterproof advertising display device that includes a captive calculator.
U.S. Pat. No. 5,906,383 to Cortes relates to a combination shopping cart and basket includes a basket member with a pair of opposing gripping members to assist a user in lifting the device. The basket member is dimensioned to be received within a vehicle's trunk.
U.S. Pat. No. 5,899,285 to Curbelo relates to a Motorized personal shopping cart. Lastly,
U.S. Pat. No. 4,199,170 to Hubner, et al. relates to a collapsible shopping cart supported for transport on the bumper of an automobile by brackets.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a shopping cart modified for vehicle transport and advertising method.
In this respect, the shopping cart modified for vehicle transport and advertising method according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides a new shopping cart modified for vehicle transport and advertising method which can be used for transporting groceries without unloading the contents of a shopping cart into an automotive vehicle. And can be used for displaying advertising placards on the side walls, front wall, and rear wall thereof whereby to carry promotional material which is visible to a user person and the other shoppers, and the advertising method wherein the promotional material generates additional income to a owner of the shopping cart by increasing sales and providing a payback of the shopping cart.
Therefore, it can be appreciated that there exists a continuing need for a new shopping cart modified for vehicle transport and advertising method which can be used for transporting groceries without unloading the contents of a shopping cart into an automotive vehicle. And can be used for displaying advertising placards on the side walls, front wall, and rear wall thereof whereby to carry promotional material which is visible to a user person and other shoppers, and the advertising method wherein the promotional material generates additional income to a owner of the shopping cart by increasing sales and providing a payback of the shopping cart. In this regard, the present invention substantially fulfills this need.
