Abstract
Abstract A shopping attachment is disclosed for direct connection to a conventional shopping cart to allow the cart to be safely utilized by and serve as a support for disabled persons. The attachment comprises a pair of spaced tubular members attachable to the shopping cart. Each of the tubular members has a wheel mounted to a lower portion thereof. The tubular members are formed to have a horizontal support section for supporting a portion of the weight of the user. The horizontal support section preferably extends forward of the wheels attached to the tubular members to provide greater support and stability to the user. A braking mechanism is disposed in engageable frictional contact with the wheel and a braking mechanism handle is provided for regulating the operation of the braking mechanism. Breaking mechanism linkage is provided to connect the braking mechanism with the actuator handle such that said braking mechanism is normally engaged to the wheel to oppose movement of the wheel, and released from engagement upon movement of the actuator handle.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
162 words
A shopping cart attachment apparatus for direct connection to a shopping cart having wheels and a cart handle in order to allow the cart to be safely used by, and serve as a support for, mobility impaired persons, the apparatus comprising: a pair of spaced tubular members, each of said members rigidly attached to the shopping cart at a first position which normally attaches a rear wheel of the shopping cart in substitution for that rear wheel and at a second position at an upper region of the shopping cart, each of said members having a wheel mounted to a lower portion thereof, each of said members having a generally-horizontal support section for supporting a portion of the weight of the user; a braking mechanism disposed adjacent each of said wheels for holding the cart in the place; and a braking mechanism actuator handle disposed adjacent at least one of said horizontal support sections for regulating the operation of said braking mechanism.
Claim 2
Dependent Claim
162 words
A shopping cart attachment apparatus for direct connection to a shopping cart having wheels and a cart handle in order to allow the cart to be safely used by, and serve as a support for, mobility impaired persons, the apparatus comprising: a pair of spaced tubular members, each of said members rigidly attached to the shopping cart at a first position which normally attaches a rear wheel of the shopping cart in substitution for that rear wheel and at a second position at an upper region of the shopping cart, each of said members having a wheel mounted to a lower portion thereof, each of said members having a generally-horizontal support section for supporting a portion of the weight of the user; a braking mechanism disposed adjacent each of said wheels for holding the cart in the place; and a braking mechanism actuator handle disposed adjacent at least one of said horizontal support sections for regulating the operation of said braking mechanism.
Claim 3
Dependent Claim
54 words
The attachment as recited in claim 1 further comprising: a braking mechanism linkage, connecting said braking mechanism to said actuator handle, operating in a manner such that said braking mechanism is normally engaged to said wheels to oppose movement of said wheels, and is released from said engagement upon movement of said actuator handle.
Claim 4
Dependent Claim
25 words
The attachment as recited in claim 1 wherein said horizontal support section extends forward of the wheels attached to the lower portion said tubular members.
Claim 5
Dependent Claim
21 words
The attachment as recited in claim 1 wherein each of said members is connected to the cart at the cart handle.
Claim 6
Dependent Claim
22 words
The attachment as recited in claim 1 wherein said horizontal support section is disposed below and substantially perpendicular to the cart handle.
Claim 7
Dependent Claim
37 words
The attachment as recited in claim 2 wherein said braking mechanism comprises an S-shaped brake shoe said brake shoe cooperating with said linkage such that said brake shoe is normally disposed in frictional contact with said wheel.
Claim 8
Dependent Claim
18 words
The attachment as recited in claim 1 wherein said tubular members are separately attachable to the shopping cart.
Claim 9
Independent Claim
109 words
An apparatus for direct connection to a shopping cart to allow the shopping cart to be safely used by, and serve as a support for, mobility-impaired persons, the apparatus comprising: a pair of spaced-apart generally tubular members, rigidly connected to the shopping cart in substitution for the rear wheels of the shopping cart, and extending from the shopping cart; a wheel attached to a lower portion of each of the members for supporting the members on the ground; and a generally horizontal support section formed in each of the members for supporting substantial portion of the weight of the user said support sections extending forward of the attached wheel.
Claim 10
Independent Claim
109 words
An apparatus for direct connection to a shopping cart to allow the shopping cart to be safely used by, and serve as a support for, mobility-impaired persons, the apparatus comprising: a pair of spaced-apart generally tubular members, rigidly connected to the shopping cart in substitution for the rear wheels of the shopping cart, and extending from the shopping cart; a wheel attached to a lower portion of each of the members for supporting the members on the ground; and a generally horizontal support section formed in each of the members for supporting substantial portion of the weight of the user said support sections extending forward of the attached wheel.
Claim 11
Independent Claim
180 words
An apparatus for use in shopping by mobility-impaired persons comprising: a partially wheeled shopping cart comprising a frame, a basket, a rearwardly disposed handle, and only one frontwardly-disposed pair of wheels, a pair of spaced-apart tubular members, each of said members rigidly attached to the rear of the shopping cart frame, each having a wheel mounted to a lower portion thereof, and each having a generally horizontal support section for supporting a portion of the weight of the user; a braking mechanism disposed adjacent each of said wheels for holding the cart in place; and a braking mechanism actuator handle disposed adjacent at least one of said horizontal support bars for regulating the operation of said braking mechanism; wherein the weight of the entire apparatus and of any items emplaced within the shopping cart basket and of any weight emplaced upon the support section by the user is borne upon four wheels only of which two are frontwardly-disposed on the shopping cart and one is upon each of the pair of tubular-members attached to the rear of shopping cart frame.
Claim 12
Independent Claim
180 words
An apparatus for use in shopping by mobility-impaired persons comprising: a partially wheeled shopping cart comprising a frame, a basket, a rearwardly disposed handle, and only one frontwardly-disposed pair of wheels, a pair of spaced-apart tubular members, each of said members rigidly attached to the rear of the shopping cart frame, each having a wheel mounted to a lower portion thereof, and each having a generally horizontal support section for supporting a portion of the weight of the user; a braking mechanism disposed adjacent each of said wheels for holding the cart in place; and a braking mechanism actuator handle disposed adjacent at least one of said horizontal support bars for regulating the operation of said braking mechanism; wherein the weight of the entire apparatus and of any items emplaced within the shopping cart basket and of any weight emplaced upon the support section by the user is borne upon four wheels only of which two are frontwardly-disposed on the shopping cart and one is upon each of the pair of tubular-members attached to the rear of shopping cart frame.
