First Claim
1. A hinge assembly comprising:
- a base havinga central hole; and
at least one receiving hole formed in the base;
a rotating bracket connecting to the base and havinga central shaft mounted rotatably in the central hole of the base and having a bottom and a top; and
two side shafts extending radially out of the top of the central shaft and being opposite to each other;

Abstract
A hinge assembly is mounted between a cover and a main case of an electronic appliance and has a base, a rotating bracket, two sleeves, a positioning spacer and a positioning assembly. The base connects to the main case and has a receiving hole. The rotating bracket has a central shaft and two side shafts. The sleeves connect to the cover and are mounted around the side shaft. The positioning spacer is mounted securely on the central shaft and has a positioning detent selectively aligning with the receiving hole. The positioning assembly is mounted in the receiving hole of the base and selectively engages the positioning detent. When the cover is rotated relative to the main case along the longitudinal axis, the central shaft rotates the positioning spacer relative to the positioning assembly. When the positioning assembly engages the positioning detent, the cover is positioned relative to the main case.
