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.

Abstract: An electrically weldable spring hinge comprising a housing, a recess in the housing, an outside of the housing, at least one welding projection on the outside of the housing and arranged in a region of the housing to which forces are applied during a welding operation on the housing and on the at least one welding projection. A hinge part is inserted into the recess. A spring element is inserted into the recess and is positioned and shaped to interact with the hinge element. The spring element comprises a supporting body, which is inserted into the recess including in a region of the housing at which a welding projection is provided on the outside of the housing, to support the housing in the region of the welding projection during a welding operation, and the spring element forms a supporting body for the housing at the projection.

Abstract: A spring hinge for eyewear with assembly locking elements that snap-in to place. The locking elements are in the form of a bent spring pin that is insertable in a compressed form and which, once inserted, expands to engage a stepped recess, locking it in place. The bent spring pin is formed from a single T-shaped blank allowing economical manufacturing and assembly, resulting in a secure, compact spring hinge.

Abstract: The invention relates to a spring hinge for spectacles, having a housing (3), a hinge part (5), which is arranged such that it can be displaced at least partially within the housing (3), a closure part (7), which is arranged in the housing (3), a spring (9), which is supported on the hinge part (5), on the one hand, and on the closure part (7), on the other hand, and having a stop device which has two stop elements. The invention is distinguished in that one stop element (33) is arranged on the hinge part (5), and the other stop element (63, 67) is arranged on the housing (3) or on the closure part (7), such that the capacity of the hinge part (5) for displacement counter to the spring force of the spring (9) is limited to a predetermined distance (w).
