Abstract
Abstract A surface mounted hinge particularly useful between adjacent folding wood panels or doors comprising a pair of molded plastic leaf members pivotally joined by a hinge pin common thereto and each having a planar guide surface engageable with a panel face and guide means extending at right angles to said guide surface for engaging transverse edge surfaces of the panels to accurately align cooperating hinge leaves and provide predetermined spacing between adjacent panels. A generally cylindrical mounting plug projects integrally from the mounting surface of each leaf member for insertion into a mounting socket bored inwardly of the panel face on which the hinge leaf is mounted. Each mounting plug is split longitudinally and is expandable by an axially insertable pin to lock the plug portion in its mounting socket, such expansion serving to drive extending anchor portions thereon into the walls of the mounting socket; with the expansion of the mounting plug being confined to single direction paralleling the hinge axis to avoid lateral splitting of the wood panel.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
295 words
A face mounted hinge assembly for use in pivotally interconnecting folding doors and the like, comprising: a pair of identical, unitary molded plastic hinge leaf elements, each leaf element comprising a body portion having a planar guide surface engageable with a planar door face on which it is mounted, a substantially cylindrical mounting plug portion, integral with said body portion and extending perpendicularly from said guide surface for insertion into a cylindrical walled mounting socket formed inwardly of said door face; and a pair of coaxially aligned cylindrical hub portions formed integrally with said body portion at spaced positions along one linear edge thereof and lying non-interferingly out of the plane of said guide surface; said hub portions having coaxial openings therethrough; the said linear edges of a said pair of leaf elements being aligned in opposed adjacency in assembly, with said hub portions thereat coaxially interleaved in registering alignment; a hinge pin, definitive of the hinge axis for said assembly, mounted in said axial openings and thereby pivotally interconnecting the leaf elements; guide means aligned with said hinge axis and comprising coplanar surfaces for engaging opposing lateral edges of a pair of doors interjoined by the hinge assembly whereby to uniformly space such door edges and align the assembly on said doors; each said plug portion having a central smooth walled opening extending through its said body portion and communicating with a single, lengthwise extending slot medially dividing said body portion into semi-cylindrical poRtions; and elongated anchor pin means insertable into the central opening of each said plug portion to effect controlled separation of its said semicylindrical portions transversely of said slot and directionally parallel to said hinge axis whereby to frictionally anchor the same against the walls of its associated said mounting socket.
Claim 2
Dependent Claim
295 words
A face mounted hinge assembly for use in pivotally interconnecting folding doors and the like, comprising: a pair of identical, unitary molded plastic hinge leaf elements, each leaf element comprising a body portion having a planar guide surface engageable with a planar door face on which it is mounted, a substantially cylindrical mounting plug portion, integral with said body portion and extending perpendicularly from said guide surface for insertion into a cylindrical walled mounting socket formed inwardly of said door face; and a pair of coaxially aligned cylindrical hub portions formed integrally with said body portion at spaced positions along one linear edge thereof and lying non-interferingly out of the plane of said guide surface; said hub portions having coaxial openings therethrough; the said linear edges of a said pair of leaf elements being aligned in opposed adjacency in assembly, with said hub portions thereat coaxially interleaved in registering alignment; a hinge pin, definitive of the hinge axis for said assembly, mounted in said axial openings and thereby pivotally interconnecting the leaf elements; guide means aligned with said hinge axis and comprising coplanar surfaces for engaging opposing lateral edges of a pair of doors interjoined by the hinge assembly whereby to uniformly space such door edges and align the assembly on said doors; each said plug portion having a central smooth walled opening extending through its said body portion and communicating with a single, lengthwise extending slot medially dividing said body portion into semi-cylindrical poRtions; and elongated anchor pin means insertable into the central opening of each said plug portion to effect controlled separation of its said semicylindrical portions transversely of said slot and directionally parallel to said hinge axis whereby to frictionally anchor the same against the walls of its associated said mounting socket.
Claim 3
Dependent Claim
69 words
The invention of claim 1, wherein said guide means comprises a plurality of planar leaf members, one projecting integrally from each of said hub portions at right angles to said guide surface, each such leaf member having opposing parallel planar faces aligned with the opposed, linear edges of an assembled said pair of leaf elements to simultaneously engage opposing lateral edges of the pair of doors in assembly therewith.
Claim 4
Dependent Claim
74 words
The invention of claim 1, and lengthwise extending wedge shaped rib portions and additional coplanar wedge shaped anchor lip portion on the exterior of said semi-cylindrical portions, said lip portions lying transversely of the longitudinal axis of said rib portions, and said rib and lip portions operatively responding to separation of said semi-cylindrical portions to penetrate the sidewalls of a mounting socket thereby to anchor said plug portion against rotational and axial movements therein.
