1. Field of the Invention
The present invention relates to a hinge, and more particularly to a triple positioning hinge that is compact and securely retains a monitor of a portable electronic device at three determined positions permanently.
2. Description of Related Art
A hinge is mounted between a base and a monitor of a portable electronic device and allows the monitor to rotate relative to the base for convenience of use.
Later, the hinges are further designed to have positioning elements that help the monitor of the portable electronic device to hold the monitor at an optimum angle to facilitate users to watch. However, the positioning elements of the conventional hinge normally positions the monitor at a single angle, so if the monitor is required to be position at a folded and an unfolded positions, the conventional hinge has to be provided with extra retaining components. As a result, the conventional hinges are generally constructional complicated and bulky. Moreover, deformation may occur in the components of the conventional hinges after a long-term of use and gradually cause the conventional hinges to lose the ability of securely holding the monitors.
To overcome the shortcomings, the present invention provides a triple positioning hinge to obviate or mitigate the aforementioned problems.
