Abstract
Abstract A hinge structure which can be used on a storm door or window combines a mounting frame for the door or window and a hinge leaf attachable to the door or window and having a knuckle portion registrable in a cutaway section of the frame which is of a configuration forming a registering knuckle in which pintles positioned in the knuckle of the hinge leaf can be engaged. A coil spring is positioned between the pintles with its opposite ends secured thereto. The registering knuckle portion of the hinge leaf has a large cutaway area exposing the spring therein so it can be manually engaged and temporarily moved out of the knuckle to move the pintles into the ends of the knuckle and permit the hinge leaf to be positioned in the cutaway section of the frame. Release of the spring moves the pintles into the knuckle configuration of the frame to complete the hinge structure.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
190 words
A hinge structure for mounting a closure in an opening comprising a mounting frame secured in said opening, an elongated knuckle configuration on said mounting frame, a plurality of cutaway sections in said knuckle configuration, a hinge leaf for each of said cutaway sections, an elongated secondary knuckle on said hinge leaf of substantially the same cross sectional configuration as said first mentioned knuckle configuration, a cut-out section in said secondary knuckle inwardly of the ends thereof, a pair of pintles movable longitudinally within said secondary knuckle on either side of said cut-out section therein, a spring positioned in said secondary knuckle between said pintles normally urging said pintles outwardly of the ends of said secondary knuckle, at least a portion of said spring being manually movable through and outwardly of said cut-out section of said secondary knuckle and distorted areas in the opposite ends of said secondary knuckle engaging said pintles to hold the same partially within said secondary knuckle and wherein said cut-out section in said secondary knuckle is large enough to permit a major portion of said spring to be moved outwardly of the secondary knuckle therethrough.
Claim 2
Dependent Claim
190 words
A hinge structure for mounting a closure in an opening comprising a mounting frame secured in said opening, an elongated knuckle configuration on said mounting frame, a plurality of cutaway sections in said knuckle configuration, a hinge leaf for each of said cutaway sections, an elongated secondary knuckle on said hinge leaf of substantially the same cross sectional configuration as said first mentioned knuckle configuration, a cut-out section in said secondary knuckle inwardly of the ends thereof, a pair of pintles movable longitudinally within said secondary knuckle on either side of said cut-out section therein, a spring positioned in said secondary knuckle between said pintles normally urging said pintles outwardly of the ends of said secondary knuckle, at least a portion of said spring being manually movable through and outwardly of said cut-out section of said secondary knuckle and distorted areas in the opposite ends of said secondary knuckle engaging said pintles to hold the same partially within said secondary knuckle and wherein said cut-out section in said secondary knuckle is large enough to permit a major portion of said spring to be moved outwardly of the secondary knuckle therethrough.
Claim 3
Dependent Claim
41 words
The structure set forth in claim 1 and wherein said spring is a coil spring and the end convolutions thereof are frictionally engaged on the innermost opposite ends of said pintles so as to be attached thereto and be movable therewith.
Claim 4
Dependent Claim
54 words
The structure set forth in claim 1 and wherein said pintles have extensions on their innermost opposite ends with respect to said secondary knuckle in which they are positioned, said extensions being of relatively smaller diameter than the remainder of said pintles and wherein the ends of said spring are engaged on said extensions.
