Abstract

A hinge has a guiding component, a sliding component and a pivoting device. The guiding component has a base and a track. The base has a top, a free end, a pivoting end and a pivoting portion. The pivoting portion is formed on the pivoting end. The track is mounted on the top of the base near the free end and has two wings. The wings protrude out respectively and traversely from the track. The sliding component is slidably mounted around the track and has a bottom and two recesses. The recesses are formed on the bottom of the sliding component, are opposite to each other and are respectively mounted around the wings. The pivoting device is pivotally mounted to the pivoting portion of the guiding component. Therefore, the guiding component is mounted slidably on the guiding component and pivotally to the pivoting device.

Claims

1. A hinge comprising

a guiding component having

a base having

a top;

a free end;

a pivoting end opposite to the free end; and

a pivoting portion formed on the pivoting end;

a track mounted on the top of the base near the free end and having

two sides; and

two wings protruding out respectively and traversely from the two sides and each wing of the track having

multiple gaps extending forward the top of the base, and each gap of one wing corresponding to one gap of the other wing; and

multiple notches formed on the edge of the wing;

a sliding component slidably mounted around the track of the guiding component and having

two ends;

a bottom; and

two recesses formed on the bottom, opposite to each other and respectively mounted around the two wings, wherein the track further has

multiple rollers each mounted in two corresponding gaps of the two wings and across the two wings; and

two fixed bearings each mounted around one of the two wings and in one of the recesses of the sliding component and having

a slit mounted around a corresponding wing; and

multiple bulges each formed in the slit of each fixed bearing and mounted in one of the multiple notches; and

a pivoting device mounted pivotally to the pivoting portion of the base of the guiding component.

2. The hinge of claim 1, wherein

the guiding component further has

a rail mounted between the two wings and having

at least one protrusion protruding from the top of the base;

and

wherein the sliding component further has

at least one positioning portion formed on the bottom of the sliding component between the two recesses near one of the two ends of the sliding component and selectively engaging the at least one protrusion of the rail.

3. The hinge of claim 2, wherein

the rail has two protrusions;

and

the sliding component has

two positioning portions.

4. The hinge of claim 2, wherein the pivoting device has

a pintle non-circular in cross section and having a proximal end and a distal end;

a stationary leaf attached securely to the proximal end of the pintle;

a limiting member mounted securely on the pivoting portion of the base of the guiding component and having

an outer surface opposite to pivoting portion of the base; and

a stop formed on and protruding from the outer surface of the limiting member;

a positioning member mounted securely on the pivoting portion of the base of the guiding component opposite to the limiting member and having

an outer surface opposite to the pivoting portion of the base; and

a detent formed on the outer surface of the positioning member; and

a washer assembly mounted around the pintle and having

a limiting washer mounted securely on the pintle and having

an annular edge; and

a limit formed on and protruding traversely from the annular edge and corresponding to and selectively abutting the stop on the limiting member to limit a rotating angle of the pintle;

a positioning washer mounted securely around the pintle and having

an inner surface adjacent to the positioning member;

an outer surface opposite to the inner surface;

an annular edge; and

a detent formed on the outer surface of the positioning washer and selectively engaging the detent of the positioning member;

a biasing member being mounted around the pintle; and

a fastener being mounted securely on the distal end of the pintle.

5. The hinge of claim 1, wherein the pivoting device has

a pintle non-circular in cross section and having a proximal end and a distal end;

a stationary leaf attached securely to the proximal end of the pintle;

a limiting member mounted securely on the pivoting portion of the base of the guiding component and having

an outer surface opposite to pivoting portion of the base; and

a stop formed on and protruding from the outer surface of the limiting member;

a positioning member mounted securely on the pivoting portion of the base of the guiding component opposite to the limiting member and having

an outer surface opposite to the pivoting portion of the base; and

a detent formed on the outer surface of the positioning member; and

a washer assembly mounted around the pintle and having

a limiting washer mounted securely on the pintle and having

an annular edge; and

a limit formed on and protruding traversely from the annular edge and corresponding to and selectively abutting the stop on the limiting member to limit a rotating angle of the pintle;

a positioning washer mounted securely around the pintle and having

an inner surface adjacent to the positioning member;

an outer surface opposite to the inner surface;

an annular edge; and

a detent formed on the outer surface of the positioning washer and selectively engaging the detent of the positioning member;

a biasing member mounted around the pintle; and

a fastener mounted securely on the distal end of the pintle.

6. The hinge of claim 3, wherein the pivoting device has

a pintle non-circular in cross section and having a proximal end and a distal end;

a stationary leaf attached securely to the proximal end of the pintle;

a limiting member mounted securely on the pivoting portion of the base of the guiding component and having

an outer surface opposite to pivoting portion of the base; and

a stop formed on and protruding from the outer surface of the limiting member;

a positioning member mounted securely on the pivoting portion of the base of the guiding component opposite to the limiting member and having

an outer surface opposite to the pivoting portion of the base; and

a detent formed on the outer surface of the positioning member; and

a washer assembly mounted around the pintle and having

a limiting washer mounted securely on the pintle and having

an annular edge; and

a limit formed on and protruding traversely from the annular edge and corresponding to and selectively abutting the stop on the limiting member to limit a rotating angle of the pintle;

a positioning washer mounted securely around the pintle and having

an inner surface adjacent to the positioning member;

an outer surface opposite to the inner surface;

an annular edge; and

a detent formed on the outer surface of the positioning washer and selectively engaging the detent of the positioning member;
