Abstract

A spring hinge for spectacles includes a housing, a hinge element, at least one spring element, and a blocking body. The housing has a recess which at least partially accommodates the hinge element, the at least one spring element, and the blocking body. The spring element and the blocking body are coupled directly to one another. At least one spring element subjects the blocking body to a prestress force on account of which the blocking body can be displaced out of an unlocking position into a locking position in which it interacts with a locking surface.
