1. Field of the Invention
The present invention relates to a hinge, and more particularly to a slidable hinge for a portable electronic device that allows a cover of the portable electronic device to move upon and rotate relative to a base to provide more applicability.
2. Description of Related Art
Portable electronic devices such as notebook computers, cellular phones and the like are commonly used in daily life. Generally, a portable electronic device comprises a base, a cover and a hinge. The cover usually has a display. The hinge pivotally connects the cover to the base, and allows the cover to pivot away from the base when the electronic device is in use.
However, as more and more functions or programs in the portable electronic device have been developed, said conventional hinges that pivot the cover in a single axis gradually become inadequate to use. For example, the conventional hinge provides no function to make the cover transversely rotate relative to the base. Such that when games are played or a movie is displayed, the portable electronic device should be rotated to provide a best viewing angle.
To overcome the shortcomings, the present invention provides a slidable hinge for a portable electronic device to obviate or mitigate the aforementioned problems.
The main objective of the present invention is to provide a slidable hinge for a portable electronic device that allows a cover of the portable electronic device to move upon and rotate relative to a base to provide more applicability.
To achieve the objective, the slidable hinge in accordance with present invention comprises a stationary leaf and a sliding leaf being mounted respectively to the base and the cover.
The stationary leaf has at least two guiding grooves singularly formed substantially perpendicularly therethrough in a curved, manner. The sliding leaf has at least two guiding elements slidably mounted respectively in the guiding grooves of the stationary leaf. With the guiding elements sliding along the guiding grooves, the sliding leaf slidably rotates relative to the stationary leaf a perpendicular angle relative to the stationary leaf.
Therefore, the portable electronic device as a whole presents a novel posture for adapting developed functions or programs.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The stationary leaf (11) has a top, a bottom, a resilient mount (111), a longitudinal guiding groove (112) and a transverse guiding groove (113). The resilient mount (111) is formed in the stationary leaf (11) and may have a fastener mounted therein. The longitudinal guiding groove (112) is curved and formed through the stationary leaf (11) and has a proximal end (1120) and a distal end (1121). The transverse guiding groove (113) is curved and formed through the stationary leaf (11), substantially perpendicularly to the longitudinal guiding groove (112) and has a proximal end (1130) and a distal end (1131). A linear separation of the proximal ends (1120)(1130) of the longitudinal and transverse guiding grooves (112)(113) is equal to a linear separation between the distal ends (1121)(1131) of the longitudinal and transverse guiding grooves (112)(113), and the linear separations are perpendicular to each other.
The sliding leaf (12) is mounted slidably on the stationary leaf (11) and has a bottom and two guiding elements (121). The bottom of the sliding leaf (12) is disposed adjacent to the top of the stationary leaf (11). The guiding elements (121) are attached to the bottom of the sliding leaf (12) and are slidably mounted respectively in the longitudinal and transverse guiding grooves (112)(113).
The resilient element (13) may be a helical torsion spring, is mounted on the bottom of the stationary leaf (11) and has a stationary end (130) and a sliding end (131). The stationary end (130) is connected securely to the stationary leaf (11), may be mounted securely on the resilient mount (111). The sliding end (131) is connected securely to one of the guiding elements (121) of the sliding leaf (12), thereby providing the sliding leaf (12) with a resilient force to retain the sliding leaf (12) in position.
