Abstract
A transversely movable hinge has a central bracket and two tilt hinge assemblies and is mounted between a cover and a base of an electronic device to allow the cover to pivot and rotate relative to the base. Each tilt hinge assembly has a pivoting leaf with a mounting segment, a torque washer and a biasing assembly. The torque washer is rotated relative to the mounting segment and has at least one protrusion. The biasing assembly presses the torque washer so the protrusion rubs against the mounting segment to provide a larger force to hold the cover at any visual angle. Then even if the resilient force of the biasing assembly is reduced to allow the cover to be easily moved transversely relative to the base, the hinge can still provide enough holding force.

A transversely movable hinge comprising:
- a central bracket having
- two sides;
- a central pintle having a bottom and two sides;
- and
- two side shafts formed transversely respectively on the sides of the central pintle;
- two tilt hinge assemblies respectively connecting to the side shafts of the central bracket, and each tilt hinge assembly comprising
- a rod connecting securely to the central bracket;
- a pivoting leaf having a mounting segment mounted around the rod;
- each mounting segment having
- an outer surface facing the inner surface of a corresponding torque washer;
- and
- at least one detent formed in the outer surface of the mounting segment;
- a torque washer mounted securely on the rod and having
- an inner surface;
- and
- at least one protrusion formed on the inner surface of the torque washer and rubbing against the mounting segment of the pivoting leaf;
- a biasing assembly mounted around the rod to press the torque washer against the mounting segment of the pivoting leaf;
- and
- a fastening washer mounted securely on the rod;
- and
- a rotating hinge assembly connecting rotatably to the central pintle of the central bracket comprising
- a stationary bracket mounted around the central pintle and having a top, a bottom and two opposite through holes;
- a bearing housing mounted around the central pintle, mounted securely in the top of the stationary bracket and having two through holes opposite to each other and respectively aligning with the through holes in the stationary bracket;
- a holding spacer mounted around the central pintle, mounted securely in the top of the stationary bracket adjacent to the bearing housing and having
- a bottom surface;
- and
- two ball bearing recesses formed in the bottom surface of the holding spacer opposite to each other and respectively aligning with the through holes in the bearing housing;
- a resilient spacer mounted around the central pintle and mounted securely in the top of the stationary bracket adjacent to the holding spacer;
- a positive stop mounted around the central pintle and mounted securely on the top of the stationary bracket to hold the resilient spacer, the holding spacer and the bearing housing in the top of the stationary bracket;
- a fastening board attached securely on the bottom of the central pintle, mounted on the bottom of the stationary bracket and having
- a top surface;
- a race formed in the top surface of the fastening board and corresponding to the through holes in the stationary bracket;
- and
- two positioning detents formed oppositely in the race and respectively aligning with the through holes in the stationary bracket;
- and
- two balls sliding in the race in the fastening board and selectively engaging the positioning detents in the fastening board, and each ball mounted in a corresponding ball bearing recess in the holding spacer, mounted in a corresponding through hole in the stationary bracket and in the bearing housing and extending out of the corresponding through hole in the stationary bracket.
