Hinge

摘要

The hinge includes an tubular element, a pair of curved beams which are arc-shaped, and a pair of positioning pins. Two curved through holes are formed in the tubular element and are aligned in parallel to each other, the pair of positioning pins are fixed on two opposite sidewalls of the tubular element, each of the pair of curved beams defines a protrusion on an external surface thereof. The pair of curved beams respectively slide in the two curved through holes and the two protrusions are configured to limit a position where the pair of curved beams are in the two curved through holes.

1. A hinge comprising:
a tubular element having a first end and an opposing second end, the tubular element defining a first through hole and a second through hole parallel with the first through hole, each of the first and second through holes extending from the first end to the second end along a curved course; a first curved beam slidaby received in the first through hole, the first curved beam having a first distal end exposed outside the tubular element adjacent to the first end of the tubular element and an opposing second distal end; a first mounting plate connected to the first distal end of the first curved beam; a second curved beam slidably received in the second through hole, the second curved beam having a first distal end exposed outside the tubular element adjacent to the second end of the tubular element and an opposing second distal end; and a second mounting plate connected to the first distal end of the second curved beam; wherein the first and second curved beams are slidable relative to the tubular element between a first position where the second distal end of the first curved beam is moved adjacent to the first end of the tubular element and the second distal end of the second curved beam is moved adjacent to the second end of the tubular element, and a second position where the second distal end of the first curved beam is moved adjacent to the second end of the tubular element and the second distal end of the second curved beam is moved adjacent to the first end of the tubular element.
