Patent ID: 7823255

Claim:
A hinge assembly, comprising: a frame; a first rotating module comprising a first pivotal shaft non-rotatably connected to the frame; and a second rotating module comprising: a second pivotal shaft being substantially perpendicular to the first pivotal shaft, a first end of the second pivotal shaft being fixed on the frame, the second pivotal shaft comprising a flange; a plurality of resilient washers a sleeve; a latching member sleeved on the second pivotal shaft, wherein the latching member is positioned between the flange of the second pivotal shaft and the sleeve, and rotatable with the second pivotal shaft, the latching member defines two latching grooves in a cylindrical surface; a rotating member engaging with the supporting member, the rotating member comprising two engaging pieces extending out from opposite sides; wherein the sleeve sleeved on the second pivotal shaft and following the rotation of the second pivotal shaft, wherein the resilient washers and the rotating member are received in the sleeve, the sleeve forms two opposite protrusions extending out from a first end of the sleeve and engaging in the latching grooves of the latching member, and the sleeve defines two opposite cutouts in a second end opposite to the first end of the sleeve and engages with the engaging pieces of the rotating member; a supporting member; and a limiting member; wherein the latching member, the plurality of resilient washers, the sleeve, the rotating member, the supporting member, and the limiting member are orderly sleeved on a second end of the second pivotal shaft; the limiting member prevents the resilient washers, the rotating member, and the supporting member from detaching out of the second pivotal shaft; the second pivotal shaft is capable of driving the rotating member to rotate.
