Patent ID: 8136940

Claim:
A pair of eyeglasses, comprising: a lens frame unit having a pair of lateral sides; a pair of temples; a pair of pivot connection units, each rotatably coupling a corresponding one of the temples to a corresponding one of the lateral sides of the lens frame unit, each of the pivot connection units including a coupling seat coupled to the corresponding one of the lateral sides of the lens frame unit, a pivoting section formed on one end of the corresponding one of the temples, an axle formed on one of the pivoting section and the coupling seat and extending along a horizontal pivot axis, the other one of the coupling seat and the pivoting section being formed with an axle opening through which the axle is rotatably inserted to permit rotation of the pivoting section relative to the coupling seat about the horizontal pivot axis, a first engaging portion disposed on the other one of the pivoting section and the coupling seat and extending into the axle opening, and a second engaging portion extending radially and outwardly from the axle and cooperating with the first engaging portion to resist movement of the pivoting section relative to the coupling seat along the horizontal pivot axis; and a pair of limiting units, each limiting angular movement between the pivoting section of a corresponding one of the pivot connection units and the coupling seat of the corresponding one of the pivot connection units, each of the limiting units including a channel structure formed on one of the coupling seat and the pivoting section of the corresponding one of the pivot connection units, and having an entry end and a blocking end that are vertically opposite to each other, and a stop formed on the other one of the coupling seat and the pivoting section of the corresponding one of the pivot connection units, extended into the channel structure via the entry end, movable in the channel structure between the entry end and the blocking end, and limited from further movement in the channel structure by the blocking end.
