Field of Invention The present invention is for a rideable add-on powered drive source for pushing standard hand-pushed carrying carts. The invention is particularly suited to work with carts that have rigid mounted rear wheels and swivel front wheels such as; shopping carts, dollies, airport baggage carts or any similar carrying platform that utilizes a pushing handle, a set of rigid mounted rear wheels and swivel mounted front wheels. The potential fields of use for this to invention are wide and varied and the preferred embodiment described herein is in no way meant to limit the use of the invention to a particular field chosen for exposition of the details of the invention. Some of the more obvious applications are mentioned herein in the interest of identifying unique properties of this general purpose article of manufacture.
It is to be understood from the outset that the scope of this invention is not limited to these fields or to the i5 specific example of potential uses presented hereinafter.
Background of the Invention Devices for pulling non-powered vehicles are old and well known in the art.
Less common is the art pertaining to the pushing of self-sustaining, independently operable vehicles 2o with a detachable pusher.
Retail stores having shopping carts for carrying the merchandise purchased require that the purchaser push the shopping cart around the shopping environment through aisles to the check-out counter. Recently, some powered means have been developed to move shopping 25 carts, including nested shopping carts from the parking lot back into the store. However, all the known prior art suffers from disadvantages and problems. The following patents relate to vehicles and components similar in nature. As it will be seen, the simplicity and effectiveness of the present invention is not revealed in the prior art.
3o U.S. Patent 5,439,069 issued to Beeler, Mar. 18, 1994 provides a nested shopping cart pusher that requires the user to walk behind the shopping cart and to control direction and power by means of hand controls mounted on the vehicle. The patent is specifically for pushing nested shopping carts and not to be used for individual shopping carts inside the store. No provision has been made to ride on the vehicle or use the shopping cart as the steering mechanism.
U.S. Patent 4,771,840 issued to Keller on Sep. 20, 1988 provides a shopping cart pusher with a single driven wheel that requires the user to control the vehicle from the back of the vehicle. The shopping cart has to be modified by the attachment of a special articulated joint. By contrast, no modification is required to the shopping cart by the present invention. In further contrast, the present invention allows the user to ride above the drive system and use the shopping cart as the steering mechanism.
io U.S. Patent 2,749,996 Issued to Parker et al June 12, 1956 shows a sweeper drive wheel raising means. The patent is not directed to a device for pushing other vehicles and does not show any inter-vehicle connection. By contrast, the present invention is directed to a pushing/pulling vehicle for shopping carts and similar hand pushed carts, thus requiring an inter vehicle connection.
German Patent DT 24 50 692, Issued to Welter, April 29, 1976 shows a modified fork lift truck with a remote control for pushing shopping carts. The inter-vehicle connection appears to be a "dummy" shopping basket which attaches to the fork lift rails which in tum is inserted into other shopping carts. By contrast, the present invention utilizes individual shopping carts that can be used for in-store shopping.
German Patent 23 50 308, Issued to Wiedman, April 17, 1975 provides a three wheel transporter for moving nested shopping carts by means of a nose cone that inserts into the 2s shopping carts. By contrast, the present invention attaches to the base of the cart and utilizes the cart as the steering mechanism while the user rides on a seat over the power train.
It will be noted that none of the prior art devices provides the simplicity of operation for a single shopping cart within the shopping store. None of the above inventions and patents, taken 3o either singly or in combination, is seen to describe the instant invention.
Summary of the Invention Briefly, the invention comprises of a powered pusher/puller that the user rides on and 3s utilizes a shopping cart as the steering mechanism. A strategically located drive wheel or

4 The linkage system and drive system provides the user with a method of eliminating manual pushing of a carrying vehicle while providing a seated unit with a turning radius equivalent to walking and pushing the same carrying vehicle.
The rear wheels of the carrying vehicle become the front steering wheels when connected to the powered unit.
Maneuverability of the carrying vehicle is achieved by utilizing the carrying vehicle's handle in the same manner as when one steers the carrying vehicle when pushing it.
Movement of the handle transfers direction changes through a linkage system to vertically rotate the drive wheel or wheels in the opposite direction of the front wheels being steered, thereby decreasing the required turning radius.
is The linkage system transmits the turning motion of the cart being pushed to a vertically rotatable drive wheel or wheels, located in the powered ridable unit under the seat area of the unit. This can be achieved by means of a direct flexible chain or belt system, electrical stepping motors, or direct mechanical linkages such as the one described in fig. 5.
Attaching a cross member that extends across the rear of the carrying vehicle to be pushed, close to the rear 2o wheels as possible facilitates assembly. A swivel mechanism is centrally located on that cross member; the top part of the swivel is connected to the front section of the frame of the powered vehicle; and the underneath of the swivel is connected to the cross member.
Off-centered from the swivel attached to the cross member, at a right angle, is a directional beam that extends under the frame towards the powered drive source. Lateral travel stops are located on the 2s frame to eliminate the possibility of over turning the drive wheels. A
linkage, consisting of a connecting rod or bar, connects this rigid beam at its termination point from the cross member to a connecting arm. Extending from the powered drive, this arm is on the opposite side of the centerline of the frame and opposite the front swivel, being parallel to the cross member directional beam.
The powered drive wheel or wheels are rotated vertically in the opposite direction of the steering wheels (rear wheels of the carrying vehicle) by the lateral movement of the beam from the cross member caused by pushing the handle of the carrying cart left or right. This transfers

5 direction changes to the connecting rod against the drive wheel arm, causing the drive wheel or wheels to rotate about a vertical axis in the opposite direction.
The primary advantage of this invention is the elimination of physical walking behind and pushing a loaded canying vehicle and at the same time, providing a seat for the operator. The driven cart with the linkage described can travel wherever a hand-pushed cart can go.
The drive source is strategically mounted under the seat and consists of a power source and drive wheel or wheels. The drive wheels) are not in a fixed position, they are mounted for 1o rotation about a vertically extending axis. Directional changes of the drive wheels) are controlled by a linkage hookup to the carrying vehicle.
A forward and reverse speed control is mounted on the existing carrying cart handle.
Power is achieved by depressing a paddle below the handle using either thumb to activate the power source. This allows the user to steer and power the carrying cart in the same manner as he or she would normally when pushing the carrying cart by hand The advantage of rotating the drive wheels in concert with the front wheels is the tighter turning radius the total unit achieves.
