Patent ID: 8683649

Claim:
An automatically closing hinge, comprising: a fixed shaft; a first body mounted on the fixed shaft; a second body pivotable with respect to the first body and comprising a rotary sleeve rotatably mounted on the fixed shaft, the rotary sleeve having a receiving cavity; an axial moving member disposed inside the fixed shaft and movable in an axial direction of the fixed shaft; a radial moving member disposed adjacent to the axial moving member inside the fixed shaft and movable in a radial direction of the fixed shaft, wherein the second body pivoting rearward in relation to the first body enables an inward radial movement of the radial moving member, and during the inward radial movement the radial moving member pushes the axial moving member and causes a forward axial movement of the axial moving member; and an energy storing member disposed in the fixed shaft and configured to store energy during the forward axial movement of the axial moving member and to release energy for driving the axial moving member to make a reverse axial movement, wherein during the reverse axial movement the axial moving member pushes the radial moving member to make an outward radial movement; wherein the radial moving member during the outward radial movement drives the second body to pivot forward in relation to the first body.
