Abstract
Abstract A cabinet hinge having a two-piece door part which is constructed as an inlet housing composed of an outer, cup-shaped housing piece which can be fastened in a mating inlet in a cabinet door, and a separately made insert piece which can be fitted into the outer housing piece and snap-fastened therein and which is pivotingly linked to the supporting wall part of the hinge. Within the insert piece there is integrated a known over-center mechanism formed of a spring-biased tongue cooperating with a countersurface, whose spring mounted in the insert piece engages at its extremity remote from the tongue a locking element which is displaceably mounted on the insert piece and which is provided with at least one, preferably two, catch projections which, when the insert piece is in its proper position in the outer housing piece, catch in recesses provided in the latter.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
155 words
A cabinet hinge having a supporting wall part and a two-piece door part which is constructed as an inlet housing having an outer, cup-shaped housing piece adapted to be fastened in a mating inlet in a cabinet door and having at least one recess, and a separate insert piece adapted to be fitted into the outer housing piece and snap-fastened therein and which is pivotingly linked to said supporting wall part, an over-center mechanism integrated in said insert piece and formed of a spring-biased tongue cooperating with a counter-surface, a spring mounted in the insert piece and pretensioning said tongue, a locking element engaged by the extremity of the spring remote from the tongue, said locking element being displaceably mounted at the insert piece and provided with at least one catch projection means which, when the insert piece is in its proper position in the outer housing piece, catches in said at least one recess.
Claim 2
Dependent Claim
155 words
A cabinet hinge having a supporting wall part and a two-piece door part which is constructed as an inlet housing having an outer, cup-shaped housing piece adapted to be fastened in a mating inlet in a cabinet door and having at least one recess, and a separate insert piece adapted to be fitted into the outer housing piece and snap-fastened therein and which is pivotingly linked to said supporting wall part, an over-center mechanism integrated in said insert piece and formed of a spring-biased tongue cooperating with a counter-surface, a spring mounted in the insert piece and pretensioning said tongue, a locking element engaged by the extremity of the spring remote from the tongue, said locking element being displaceably mounted at the insert piece and provided with at least one catch projection means which, when the insert piece is in its proper position in the outer housing piece, catches in said at least one recess.
Claim 3
Dependent Claim
15 words
A cabinet hinge according to claim 1, wherein said catch projection means comprises two projections.
Claim 4
Dependent Claim
91 words
A cabinet hinge according to claim 1, comprising two hinge links in the manner of a four-point linkage articulating the insert piece to the supporting wall part, pivot pins holding the hinge links on the door part side of the hinge, at least one of said pivot pins being made of such length that its extremities project slightly from the insert piece on both sides, said outer housing piece having undercut recesses which receive the projecting ends when the insert piece is in the correct position in the outer housing piece.
Claim 5
Dependent Claim
80 words
A cabinet hinge according to claim 1, wherein said locking element is stamped from sheet metal and has an approximate U shape in plan, with limbs and a cross member joining the limbs, the limbs being carried in flat engagement with the insert piece, while the spring of the over-center mechanism engages the cross member, the catch projection means being formed on the limbs and pointing in the direction of the force of the spring acting on the locking element.
Claim 6
Dependent Claim
73 words
A cabinet hinge according to claim 4, comprising a relatively short tab bent over at approximately right angles and formed on the cross member of the locking element, said tab being guided in a recess in the insert piece, which last mentioned recess is open at least adajcent the free end of the tab for engagement by a tool, whereby the locking element can be pushed rearwardly against the action of the spring.
Claim 7
Dependent Claim
39 words
A cabinet hinge according to claim 4, wherein flat recesses are provided in the insert piece and wherein the free ends of the limbs of the U of the locking element are guided longitudinally displaceably in said flat recesses.
Claim 8
Dependent Claim
71 words
A cabinet hinge according to claim 4, wherein said tongue has a pivot axis, a pivot pin mounting the tongue pivotingly in said insert piece, the free ends of the limbs of the U of the locking element being guided in the vicinity of the pivot axis of the tongue of the over-center mechanism, said pivot pin passing through bearing bores in the ends of the limbs of the locking element.
