Spring hinge for spectacles

摘要

The spring hinge has two hinge portions (1,2) interconnected by a hinge shaft (3). A bearing fork (4) is provided in the hinge portion (2). A coil spring (14) is slidably guided with the aid of a slider (6) in a housing (7). The coil spring is extended on a web (8) of slider and supported on a housing-fixed abutment (13). A passage opening (16) in the hinge portion (2) is connected to the slider inserted coaxially to the coil spring in the housing. The abutment is attached to the helical spring receiving sleeve (15) that is protruded into the region of the hinge shaft.
