Abstract
Abstract A hinge for a flush-type door comprising a plate member which has two integral, elongate, generally flat and mutually perpendicular portions and adapted for mounting to the door so that a first of the portions abuts the door edge and the other portion abuts an adjoining face of the door. A pivot pin is supported along a free longitudinal edge of the portion of the plate member which abuts the door edge. A hinge arm is pivotally supported on the pivot pin and is mounted to a face of the furniture member or the like to which the door is hinged. The hinge arm has a width measured along the axis of the pivot pin which is substantially less than the length of the plate member abutting the door edge. A recess is defined in the plate member whose width along the axis of the hinge pivot slightly exceed that of the width of the hinge arm so as to permit the hinge arm to be received within the recess when the door is in its closed position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
181 words
A hinge for a flush-type door comprising: a first plate member having two integral, elongate, generally flat, and mutually perpendicular portions for mounting to one of the elements to be hingedly connected with a first of said portions abutting an edge of said one element and the other of said portions abutting a face of said element which adjoins said edge, a pivot means supported along a free longitudinal edge of said first portion of said first plate member, a hinge arm pivotally supported on said pivot means for mounting to a face of the other said element to be hingedly connected and having a width measured along the axis of said pivot means which is substantially less than the length of said first plate member also measured along said axis, said first and second portions of said first plate member defining a recess whose length along said axis slightly exceeds that of the width of said hinge arm so as to permit said hinge arm to be received within the said recess when the door is in its closed position.
Claim 2
Dependent Claim
181 words
A hinge for a flush-type door comprising: a first plate member having two integral, elongate, generally flat, and mutually perpendicular portions for mounting to one of the elements to be hingedly connected with a first of said portions abutting an edge of said one element and the other of said portions abutting a face of said element which adjoins said edge, a pivot means supported along a free longitudinal edge of said first portion of said first plate member, a hinge arm pivotally supported on said pivot means for mounting to a face of the other said element to be hingedly connected and having a width measured along the axis of said pivot means which is substantially less than the length of said first plate member also measured along said axis, said first and second portions of said first plate member defining a recess whose length along said axis slightly exceeds that of the width of said hinge arm so as to permit said hinge arm to be received within the said recess when the door is in its closed position.
Claim 3
Dependent Claim
68 words
The hinge in claim 1 wherein said recess is defined at least in part by opposing parallel sidewalls which both lie at a right angle to the plane of the edge of said one element, said recess also forming a protuberance on said first plate member to facilitate locating said first plate member in a recess cut into the edge and face of said one hingedly connected element.
Claim 4
Dependent Claim
74 words
The hinge of claim 1 which further includes a generally part-cylindrical member for mounting within a mating cylindrical bore formed in the face of said one element but with said bore communicating with the edge of said one element, said part-cylindrical member defining therein a recess in the portion thereof which faces the edge of said one element so as to receive the protuberance formed on said first plate member by its said recess.
Claim 5
Dependent Claim
52 words
The hinge of claim 1 wherein said hinge arm comprises a pair of parallel spaced ribs whose plane is perpendicular to the hinge pivot axis, and catch means supported in said recess on said first plate member and disposed between said pair of ribs when the door is in its closed position.
Claim 6
Dependent Claim
22 words
The hinge of claim 4 wherein the height of said ribs is tapered downwardly toward the location of the hinge pivot axis.
Claim 7
Dependent Claim
21 words
The hinge of claim 4 wherein said catch means co-acts with a pawl supported by said ribs on said hinge arm.
Claim 8
Dependent Claim
28 words
The hinge of claim 6 wherein said pawl is spring biased to a position where it engages said catch means when said door is in its closed position.
