Abstract
Abstract An over-center hinge for thin doors of cabinets, especially those of bathroom mirrored cabinets, having a thin door-related part which can be fastened in a mating recess provided on the inside of the door and open at the door edge. The door-related hinge part is divided into an outer mounting plate which can be fastened in the recess of the door and is likewise open at the end adjacent the open door edge, and a separate link holder which can be inserted into the mounting plate from the open edge, on which link holder the supporting arm fastenable to a supporting wall of the cabinet is pivotingly articulated. A cap mounting projection extending from the inside of the door, to which projection there is removably fastened a molded cap which bears a tongue extends into the path of a contact surface provided on the supporting arm and is resiliently compressible by this contact surface against a spring force. The link holder engages with lateral projections in grooves of the mounting plate which extend in the inserting direction and open in the open end of the mounting plate, and fastening elements securing the link holder against withdrawal from the mounting plate.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
275 words
Over-center hinge for relatively thin doors of cabinets, especially of bathroom mirrored cabinets, comprising: a relatively thin door-related part adapted to be fastened, in a mating recess provided on the inside of the door facing the cabinet and open at the door edge, said door-related hinge part being divided into an outer mounting plate adapted to be fastened in said recess and which mounting plate is likewise open at the end adjacent the open door edge, and a separate link holder adapted to be inserted into said mounting plate from the open edge, said link holder being articulately joined to a supporting arm fastenable to a supporting wall of the cabinet, said hinge having a projection extending from the inside of the door, a molded cap removably fastened to said projection, said cap carrying a tongue extending into the path of a contact surface provided on the supporting arm and resiliently compressible by said contact surface, and on which tongue the contact surface slides during a part of the closing movement of the hinge through a dead center position, on one side of which dead center position the tongue exercises on the supporting arm through the contact surface a force acting in the hinge-open direction, and on the other side of which said tongue exercises a force in the hinge-closed direction, said link holder having lateral projections engaging in grooves of the mounting plate which extend in inserting direction and open in the open end of the mounting plate, and fastening means for securing, in a form-locking manner, the link holder in proper installed position against withdrawal from the mounting plate against the insertion direction.

Over-center hinge for relatively thin doors of cabinets, especially of bathroom mirrored cabinets, comprising: a relatively thin door-related part adapted to be fastened, in a mating recess provided on the inside of the door facing the cabinet and open at the door edge, said door-related hinge part being divided into an outer mounting plate adapted to be fastened in said recess and which mounting plate is likewise open at the end adjacent the open door edge, and a separate link holder adapted to be inserted into said mounting plate from the open edge, said link holder being articulately joined to a supporting arm fastenable to a supporting wall of the cabinet, said hinge having a projection extending from the inside of the door, a molded cap removably fastened to said projection, said cap carrying a tongue extending into the path of a contact surface provided on the supporting arm and resiliently compressible by said contact surface, and on which tongue the contact surface slides during a part of the closing movement of the hinge through a dead center position, on one side of which dead center position the tongue exercises on the supporting arm through the contact surface a force acting in the hinge-open direction, and on the other side of which said tongue exercises a force in the hinge-closed direction, said link holder having lateral projections engaging in grooves of the mounting plate which extend in inserting direction and open in the open end of the mounting plate, and fastening means for securing, in a form-locking manner, the link holder in proper installed position against withdrawal from the mounting plate against the insertion direction.
Claim 3
Dependent Claim
134 words
An over-center hinge according to claim 1, in which said molded cap is constructed so as to be adapted to be pushed matingly, in the direction of the deformation of the tongue, onto the cap mounting projection of the door-related hinge part, and to be removed from it in the opposite direction, said cap mounting projection having a T-shaped cross section in a plane at right angles to the direction of installation of the molded cap, and said molded cap having a complementary T-shaped recess opening at least at one side and at the bottom thereof, said fastening means having a fastening element provided on one of said link holder or mounting plate, said fastening element being adapted to be brought into form-locking engagement with the other of said mounting plate or link holder.
Claim 4
Dependent Claim
14 words
An over-center hinge according to claim 2, wherein said fastening element is a lip.
Claim 5
Dependent Claim
15 words
An over-center hinge according to claim 2, wherein said fastening element is a fastening screw.
Claim 6
Dependent Claim
89 words
An over-center hinge according to claim 2, wherein said mounting projection is formed of two projection parts which, when the link holder is in said proper installed position in the mounting part, constitute the cap mounting projection, one of them being fixedly joined to the mounting plate and the other fixedly joined to the link holder, and wherein on one of said projection parts the fastening means is provided in the form of a lip which, in said proper installed position, engages a rebate on the other projection part.
Claim 7
Dependent Claim
54 words
An over-center hinge according to claim 5, wherein said projection part disposed on said link holder has a section overlapping the projection part disposed on said mounting plate in the insertion direction, said lip engaging said rebate disposed in the projection part of the mounting plate being provided on the underside of said section.
Claim 8
Dependent Claim
