BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to tools, and more particularly, to a tool kit used to facilitate the changing of a vehicle wheel assembly.
2. Description of the Related Art
Most people that routinely drive a vehicle, such as an automobile, have experienced a flat tire. For some, changing a flat tire is a simple task and does not require much thought or effort. For other people however, changing a flat tire is a very difficult task. Often the difficulty arises because the person simply does not have sufficient strength to manually remove lug nuts from a wheel, or to manually operate a jack to lift the vehicle. Tools operated by manual force have been developed in the past for changing a flat tire. These tools provide for a number of more or less complicated features that fail to solve the problem in an efficient and economical way. Applicant however, is not aware of an easy-to-transport tool kit used to facilitate the changing of a vehicle wheel assembly having the novel features of the present invention.

The instant invention is a vehicular wheel changing assembly, consisting of a case assembly housing a transformer. The transformer has transfer means to transfer electrical energy from one circuit to another through inductively coupled conductors. The transformer has electrical connections to at least first and second electrical connectors. The case assembly houses a cable connector that supplies power to the transformer. The cable connector extends from the one circuit of a vehicle to the first electrical connector. The transformer has an activation switch, an illuminating indicator, and first air vents. In the preferred embodiment, the one circuit is a vehicle cigarette lighter socket or vehicle adapter designed to provide electrical power.
The case assembly comprises an exterior top wall, a first front wall, and first and second lateral walls. The case assembly also houses a socket case to store a socket assembly. The case assembly further comprises an interior top wall having at least first and second cooperatively shaped cavities to snugly receive the connector cable and power gun respectively.

An electrical power gun comprises a body, a handle, and a trigger. The electrical power gun also has an electrical cord having a plug that inserts into the second electrical connector. The electrical power gun further comprises a socket assembly having a plurality of different sized sockets that each mount thereon. At least one of the pluralities of different sized sockets is of a cooperative size to fit onto lug nuts of a vehicle wheel assembly. The socket assembly is housed in the case assembly.
A jack assembly has lifting means to lift a vehicle, whereby the jack assembly has a cooperative head to receive at least one of the pluralities of different sized sockets thereon. The jack assembly has a foot pedal to prevent the jack assembly from falling over when a torque force is applied when operating the electrical power gun onto the jack assembly.
The jack assembly can be a scissor jack assembly or a telescopic jack assembly. The scissor jack assembly comprises a lift plate, a base member, lower scissor arms, upper scissor arms, and an adapter member having a cooperative adapter head to receive at least one of the plurality of different sized sockets thereon.
