The applicant is aware of the following prior art.
U.S. Pat. No. 4,434,523 entitled, “DOOR HINGE FOR FURNITURE DOORS OR THE LIKE” issued to Grass on Mar. 6, 1984 discloses a semi-concealed hinge for mounting a door in a relatively close adjustable operating relation with a furniture side rail or frame. A socket part is adapted to be substantially fully positioned within a backwardly and edgewise open slot in the door to carry a swing arm part on a hinged knuckle in such a manner as to enable the door to be pressure-retained in a desired position, such as in a closed position. A connector or screw-on bracket-like plate is either integral with, or secured to, the swing arm part and, if it is a separate part, has a screw and slot mounted in relation with the swing arm part that enables “up” and “down” adjustment of the door with respect to the frame. The connector or screw-on plate has opposed guide flange portions that are adapted to fit over and to be carried along opposite sides of the frame and to cooperate with an inwardly positioned adjustment plate. The adjustment plate has an elongated slot and the connector plate has a central hole for receiving a frame mounting screw that adjustably operatively secures the plates on a side edge of the frame. The adjustment and connector plates have cooperating sloped or wedge surfaces which enable the connector plate to be moved inwardly and outwardly with respect to the frame in such a manner as to effect a fully parallel adjustment of the door along the front face of the frame.
U.S. Pat. No. 7,698,783 entitled, “HINGE”, issued to Heid on Apr. 20, 2010 discloses a hinge for a door. The hinge comprises a receiver assembly having a slot, a door leaf having a retaining spring biased away from the door leaf, the door leaf being dimensioned for insertion into the slot and a retaining device associated with the receiver assembly for releasably engaging the retaining spring to releasably retain the door leaf in the slot.
U.S. Pat. No. 8,516,658 entitled, “DOOR HINGE”, in particular for a building door issued to Bultschneider on Aug. 27, 2013 discloses a door hinge that has a knuckle defining a pivot axis, a pair of leaves extending from the knuckle and pivotal relative to each other about the axis, a housing fixable in a door jamb or door edge, and a holder in the housing. The holder is formed by a pair of bent sheet-metal brackets together forming a cavity in which engages one of the hinge leaves. One of the brackets has a face forming an acute angle to the axis. A pair of rotatable and externally threaded spindles extending across the cavity are threaded to the one leaf such that rotation of the spindles adjusts a position of the one leaf in the cavity relative to the holder. An adjustment screw threaded in the housing bears on the angled face so that the screw can be rotated to press against the face and cam the holder axially. A door hinge has a knuckle defining a pivot axis, a pair of leaves extending from the knuckle and pivotal relative to each other about the axis, a housing fixable in a door jamb or door edge, and a holder in the housing. The holder is formed by a pair of bent sheet-metal brackets together forming a cavity in which engages one of the hinge leaves. One of the brackets has a face forming an acute angle to the axis. A pair of rotatable and externally threaded spindles extending across the cavity are threaded to the one leaf such that rotation of the spindles adjusts a position of the one leaf in the cavity relative to the holder. An adjustment screw threaded in the housing bears on the angled face so that the screw can be rotated to press against the face and cam the holder axially.
U.S. Pat. No. 9,670,707 entitled, “DOOR HINGE”, issued to Bartels on Jun. 6, 2017 discloses a door hinge having two hinge leaves joined together at a knuckle defining a hinge axis about which the leaves are relatively pivotal and top and bottom sheet-metal parts forming a housing surrounding one of the hinge leaves. Two rotatable adjustment spindles are each journaled in the housing, rotatable about respective axes extending in a first direction perpendicular to the hinge axis, and operatively threadedly connected to the one leaf so that rotation of the spindles moves the one leaf in a first direction perpendicular to the hinge axis. A base plate between the parts is formed with respective threaded hole receiving the spindles, the base plate being secured to the one leaf for movement of the one leaf in a second direction perpendicular to the first direction relative to the base plate.
U.S. Pat. No. 8,196,265 entitled,“CONCEALED DOOR HINGE” issued to Neukoetter on Jun. 6, 2012 discloses a concealed door hinge that has first and second leaf assemblies fittable into respective mortises in an edge of the door and in the door frame. The first leaf assembly has a body, mounting tabs at ends of the body and securable to the door frame or to an edge of the door, and an insert shiftable in the body in a first horizontal direction perpendicular to a face of the assembly. The body is also shiftable relative to the tabs in a second horizontal direction transverse to the horizontal direction and parallel to the face. A swivel mechanism is connected between the second leaf assembly and the insert of the assembly. Adjusters engaged between the insert, the body, and the tabs can relatively secure the insert and body in any of a plurality of positions offset relative to one another in the horizontal directions.
The present invention is a concealed hinge assembly. The concealed hinge assembly comprises in combination an outer door hinge element consisting essentially of a flat front surface, a flat bottom surface, a configured back surface, a first side and a second side.
The configured back surface has an upper flat surface that has a first opening therethrough. The configured back surface has a lower flat surface that has a threaded opening therein. There is a hinge pin opening through the outer door hinge assembly from the first side to the second side.
There is an inner door hinge. This inner door hinge has a front, a back, a top, and the front has an outer door hinge element opening therein. The outer door hinge element opening has a back surface. The back surface has a second opening therethrough in an upper portion thereof. The inner door hinge has a first end and a second end and the inner door hinge has a third opening in the inner door hinge first end and in the inner door hinge second end a concealed hinge, this concealed hinge has two ends, a top, a back, and a front. The top has at least two pin openings therethrough.
The back has a hinge holder mounted therein near an outside edge thereof. The hinge holder consists of a projecting hook structure, a front end of the hook structure has a third opening therethrough.
There is an elongated hinge pin that has a narrowed portion near a center thereof.
There is a hinge pin retainer for insertion in the pin openings in the concealed hinge in addition to insertion across the narrow portion of the hinge pin retainer.
The present invention is a hinge that provides concealment. It has been discovered that the hinge provides concealment, security, safety and has aesthetic value.
The configured back surface 10 has an upper flat surface 16 that has a first opening through it 18. The configured back surface 10 has a lower flat surface 20 that has a threaded opening 22 in it. The first opening 18 accepts the hinge pin retainer 70. The hinge pin opening 24 the outer door hinge element 4 from the first side 12 to the second side 14. This first opening 18 accepts the hinge pin retainer 70 that locks the hinge pin 68 into place within the outer door hinge element 4. The first opening 18 runs from the upper flat surface 16 through to the hinge pin opening 24.
This concealed hinge has a first end 50 and a second end 52. The concealed hinge has a top 54, a back 56, and a front 58. The top 54 has at least two openings 60.
The back 56 has a hinge holder 62 mounted near an outside edge. The hinge holder 62 consists of a projecting hook structure 64. A front end 65 of the hook structure 64 has a third opening through 66 it.
