Abstract
A positioning hinge for providing pivotal positioning is disclosed.The positioning hinge comprises a pivotal member, a pivotal base, a first torsion spring and a friction device. The friction device includes a positioning element and a slide-friction member, which are kept in a resilient friction contact with each other by means of a resilient mechanism. This enables the LCD display to be opened due to the pivoting action of the pivotal base under the results of resilience and frictional positioning. It is appreciated that the above features advantageously result in an appropriate reduction in the opening speed of the LCD display while at the same time obtaining a steady frictional pivotal positioning, thereby prolonging the working life of the positioning hinge.
