Abstract

The present invention includes a directional wheel which has a roller movable under a force. The roller has two sides forming a first and a second leaning portions that are held by a first and a second support structures. The first support structure and the second support structure have respectively a first moving end and a second moving end movable by the first leaning portion and the second leaning portion. A first contact and a second contact are provided respectively in the moving range of the first and second moving ends to connect the first and second moving ends to generate signals. The first and second leaning portions keep two sides of the direction wheel in a balanced manner in regular conditions. The directional wheel is movable under a force to synchronously move the first and second support structures in the direction of the force to generate a corresponding signal.

Dependent claims

An integrated structure for directional wheel support and signal triggering, comprising:

a directional wheel having a roller which has two sides formed respectively a first leaning portion and a second leaning portion;
a first support structure which holds the first leaning portion and has at least one first moving end movable by the first leaning portion and a first contact located within a first moving range of the first moving end to be connected by the first moving end to generate a first signal;
and
a second support structure which holds the second leaning portion and has at least one second moving end movable by the second leaning portion and a second contact located within a second moving range of the second moving end to be connected by the second moving end to generate a second signal;
wherein the direction wheel has a left side and a right side held by the first support structure and the second support structure in a balanced manner, and is movable under a force to move synchronously the first support structure and the second support structure in the direction of the force to generate a corresponding signal.
