Slidable hinge

Abstract

A slidable hinge has a stationary leaf and a sliding leaf being respectively mounted to a base and a cover of a portable electronic device. 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 to 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.

1 . A slidable hinge comprising
 a stationary leaf having
 a top; 
 a bottom; 
 a longitudinal guiding groove being curved and formed through the stationary leaf and having a proximal end and a distal end; and 
 a transverse guiding groove being curved and formed through the stationary substantially perpendicularly to the longitudinal guiding groove and having a proximal end and a distal end; 
   a sliding leaf being mounted slidably on the stationary leaf and having
 a bottom being disposed adjacent to the top of the stationary leaf; and 
 two guiding elements being attached to the bottom of the sliding leaf and being slidably mounted respectively in the longitudinal and transverse guiding grooves; and 
   a resilient element being mounted on the bottom of the stationary leaf and having
 a stationary end being connected securely to the stationary leaf; and 
 a sliding end being connected securely to one of the guiding elements of the sliding leaf. 
   
     
     
         2 . The slidable hinge as claimed in  claim 1 , wherein
 a linear separation is defined between the proximal ends of the longitudinal and transverse guiding grooves; and   a linear separation is defined between the distal ends of the longitudinal and transverse guiding grooves and is equal to the separation between the proximal ends of the longitudinal and transverse guiding grooves.   
     
     
         3 . The slidable hinge as claimed in  claim 1 , wherein
 the stationary leaf further has a resilient mount being formed in the stationary leaf; and the stationary end of the resilient element is mounted securely on the resilient mount.   
     
     
         4 . The slidable hinge as claimed in  claim 1 , wherein the resilient element is a helical torsion spring.
