ABSTRACT:
DESCRIPTION
1. Technical Field
The present invention relates generally to switches, and more particularly to a switch for electrically powering a cart such as a wagon.
2. Background of the Invention
For many years, people, especially children, have enjoyed playing with wagons. A wagon can generally be considered one type of cart having a central frames with wheels attached to the frame. An elongated bar having a handle is attached to the frame to allow a person to pull the wagon. The bar and handle are typically made from metal, wood or plastic. A child can put toys in the wagon or even pull playmates seated in the wagon. Sometimes, a parent may pull a child in a wagon such as when taking a leisurely walk. While this is less strenuous than having to actually carry a child, the parent is still required to pull the entire weight of the wagon, including the child. This can become more difficult when pulling a number of children seated in the wagon. The strength required for pulling the wagon under these circumstances may present considerable difficulties for people having back problem or persons who cannot engage is stressful physical activity due to other reasons.
Besides for its amusement value to children or its transportation value to parents, however, wagons can also be used in many other arduous tasks, such as gardening or toting heavy items around the house or yard. Because of the heavy weights involved, a person having back problems or other medical conditions may find it difficult to pull a wagon carrying a heavy load.
The present invention is provided to solve these and other problems.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a switch for a powered wagon. A wagon generally comprises a frame having at least one wheel connected to the frame and adapted to roll along a surface. A bar is connected to the frame and has a handle for pulling on the bar and, thus, pulling the wagon. The wagon also has a motor connected to the wheel and connected to a battery.
According to a first aspect of the invention, the wagon has a switch connected to the handle, wherein the switch is activated to power the wheel by applying pressure to the switch. According to a further aspect of the invention, pressure can be applied to the switch by squeezing the handle or pulling the handle.
According to another aspect of the invention, the switch has a wire shell having a first lead extending therefrom and adapted to be connected to the motor. A pipe member has an insulator member mounted on the pipe member. The pipe member has a second lead extending therefrom and adapted to be connected to the battery. The wire shell is positioned over the pipe member and insulator member wherein the insulator member maintains a space between the wire shell and the pipe member to define an inactivated position. The wire shell is resiliently deflectable to a second position contacting the pipe member to define an activated position wherein an electrical connection is made powering the wheel of the wagon for movement along the surface.
According to another aspect of the invention, the switch can be provided in other applications in addition to a cart such as a wagon.
Other features and advantages of the invention will be apparent from the following description taken in conjunction with the following drawings.
