1. A hinge assembly comprising:

  • two tracks being opposite to each other;

    a main bracket being mounted between the tracks and having two sides;

    at least one connecting bracket attached securely to the main bracket, and each one of the at least one connecting bracket havinga distal end;

    a tongue being formed on and extending out from the distal end of the connecting bracket and having two sides; and

    two bulges being formed respectively on and extending out from the sides of the tongue; and

    at least one sliding hinge respectively corresponding to the distal end of the at least one connecting bracket and selectively holding respectively the at least one connecting bracket, and each one of the at least one sliding hinge corresponding to one connecting bracket and comprisinga base having a distal end;

    a stationary carrier being mounted securely on the base and havinga distal end;

    a top surface;

    two sides; and

    two inner grooves being formed through the stationary carrier, being respectively near the sides of the stationary carrier and being opposite to each other, and each inner groove havinga straight part being away from the distal end of the stationary carrier; and

    an inclined part being near the distal end of the stationary carrier, wherein the straight parts of the inner grooves are nearer than the inclined parts of the inner grooves;

    a sliding carrier being mounted slidably on the stationary carrier and havinga distal end; and

    two enlarged holes being formed through the sliding carrier near the distal end of the sliding carrier, and respectively corresponding to the inner grooves;

    a rotating element being mounted rotatably on the sliding carrier and havingtwo indenting sides;

    two straight sides being opposite to each other and being adjacent to the indenting sides; and

    two concaves being formed respectively in the indenting sides of the rotating element, and each concave being V-shaped and comprisinga lower point;

    two inclined edges being connected to each other at the lower point; and

    two sharps being respectively formed between the inclined edges of the concave and the straight sides of the rotating element;

    a resilient element being mounted between the sliding carrier and the stationary carrier;

    a cover being attached securely to the base and the stationary carrier, being mounted on the sliding carrier and havinga distal end;

    two sides;

    two outer grooves being formed through the cover and respectively aligning with the inner grooves of the stationary carrier, and each outer groove havinga straight part aligning with the straight part of a corresponding inner groove; and

    an inclined part aligning with the inclined part of the corresponding inner groove;

    an actuating hole being formed through the cover and being mounted around the rotating element;

    an inner wall being formed around the actuating hole and having two ends and two sides; and

    two protruding parts being respectively formed inwardly from the ends and the sides of the inner wall and selectively abutting the rotating element, and each protruding part havinga straight edge being parallel to the sides of the inner wall;

    a sharp; and

    an inclined edge being connected to the straight edge of the protruding part at the sharp of the protruding part; and

    two sliding pins being mounted between the cover and the sliding carrier, being respectively mounted slidably through the inner and outer grooves, being respectively mounted slidably through the enlarged holes of the sliding carrier and selectively abutting the tongue of the corresponding connecting bracket; and

    at least one tilting hinge being connecting to the main bracket, and each one of the at least one tilting hinge havinga stationary leaf being attached securely to the main bracket;

    a pintle being attached securely to the stationary leaf;

    a washer assembly being mounted around the pintle;

    a rotating leaf being mounted around the pintle; and

    a fastener being mounted securely around the pintle.
