<p>#CMT# #/CMT# The hinge has two hinge parts (4, 5) connected to one another in an articulated manner by a hinge axis (7). The part (5) is mounted in a hinge housing (1), such that the part is displaceable against a retracting spring force and the other part (4) is supported on the housing via a centering. The centering provided between a stopper surface of the part (5) and a front side of the housing comprises a centering groove (10) running around a circumference of the hinge axis and a centering projection (11) engaging in the groove in a stretched position of the hinge parts. #CMT#USE : #/CMT# Spring hinge for spectacles. #CMT#ADVANTAGE : #/CMT# The centering provided between the stopper surface of the hinge part and the front side of the hinge housing comprises centering groove running around the circumference of the hinge axis and the centering projection engaging in the groove in the stretched position of the hinge parts, thus ensuring play-free guidance of the spectacle earpiece largely without endangering the easy displaceability of the hinge parts mounted in the hinge housing. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a top view of a spring hinge. 1 : Hinge housing 4, 5 : Hinge parts 7 : Hinge axis 10 : Centering groove 11 : Centering projection.</p> |
