Abstract
A mechanism forming the hinges between an eyeglass frame and the lateral temple bars which allows for the rapid adjustment of the vertical alignment of the lens frame in relation to the horizontal axes of the temple pieces. The forward end of each temple piece is split into a stationary half and a sliding half. Each half terminates into a pin or ball which cooperates with a bearing at the edge of the lens frame to form a hinge allowing each temple piece to be folded against the frame. The sliding halves can be moved along the axes of the temple pieces independently from the stationary ones to tilt the hinging axis so as to change the position of the lens plane in relation to the temple pieces.
Claims7
In a pair of eyeglasses having two lateral earpieces pivotally connected to opposite sides of the lens frame, a mechanism for adjustably tilting said frame in relation to each earpiece which comprises:
- the end of said earpiece which is pivotally connected to the frame being longitudinally split into a first arm forming an integral extension of said earpiece, and a second arm slidingly and contiguously attached to said first arm;
- first means for pivotally connecting said first arm to the frame;
- second means for pivotally connecting said second arm to the frame;
- and
- means for adjustably moving said second arm toward said frame in relation to, and independently from, said first arm.
