Abstract
A roller wheel structure having a simplified design. A support guide is connected to a lower housing for constraining and allowing movement of a roller wheel and roller support. In a preferred embodiment, the support guide is integrally formed with the lower housing, reducing the part count and enabling a more compact design. On one side of the wheel, the support guides connected to the lower housing support a spring around an axle connected to a support for the roller wheel. When the roller wheel is depressed by a user, the spring allows the roller support to depress until a micro-switch is activated. On a second side of the roller wheel, the roller support consists of a mechanism which slides up and down within the support guides connected to the lower housing when the user depresses the roller wheel. This side includes a spring biased against an open inside of the roller wheel. The spring is biased against an undulating surface on the inside perimeter of the wheel, providing a ratcheting effect when a user rotates the wheel.
