Abstract
Abstract The present invention is directed to the building art, comprised generally of a door or window structure embodying a peripheral framework of horizontal and interconnecting vertical rail members, supporting by means of gasket material and suitable supporting structure glazing material. The framework is suitably mounted by hinge means for swingable or slidable movement into and out of the encasing wall opening. The horizontal and vertical rail sections when placed in abutting right angular relationship to one another are rigidly interconnected and precisely aligned with respect to one another by means of a particularly contoured connector member or corner block adapted to receive pin means through apertures in the horizontal rail section, the connector member being threadably or otherwise attached to the vertical rail section through a contoured tension-receiving plate member. In this manner, after assembly of the parts, and securement of one to the other, a crimping or crushing action is exerted upon a tongue or ''''T'''' section on the vertical rail, and a structurally sound joint is assured without resort to time-consuming welding techniques or generally equivalent expedients.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
298 words
A door construction or the like, comprising a plurality of interconnected horizontal and vertical rail members of generally channel-like configuration, one of said vertical rail members adjacent at least the bottom thereof having its spaced end walls provided with first and second horizontally aligned openings therethrough, a contoured block member located in one of said horizontal rail members adjacent at least one end thereof, said block member having a horizontally passaged base portion and a vertically passaged head portion, the passage in the base portion being in alignment with the first and second openings in the end walls of said vertical rail member, said horizontal rail member having a pair of vertically spaced parallely aligned wall sections each of which has an opening therein which aligns with the opening in the other wall section, means for rigidly connecting the block member to the horizontal rail member through the vertical passage in the block head portion and through the openings in the wall sections of said rail member, a curved plate member located within the vertical rail member and bearing against one of the end walls thereof, said plate member having a central opening therein which aligns horizontally with the openings in the vertical end wall openings and with the horizontal passage in the block member base portion, and fastening means threadably engageable with the block member through the passage in the base portion thereof and insertable for threadable engagement through the openings in the vertical rail member end walls and the central opening in the curved plate member, said fastening means upon the tightening thereof applying tension forces to the plate member and compressive forces at the juncture of the horizontal and vertical rail members, assuring accurate and precise alignment of the parts and a firm connection therebetween.
Claim 2
Dependent Claim
298 words
A door construction or the like, comprising a plurality of interconnected horizontal and vertical rail members of generally channel-like configuration, one of said vertical rail members adjacent at least the bottom thereof having its spaced end walls provided with first and second horizontally aligned openings therethrough, a contoured block member located in one of said horizontal rail members adjacent at least one end thereof, said block member having a horizontally passaged base portion and a vertically passaged head portion, the passage in the base portion being in alignment with the first and second openings in the end walls of said vertical rail member, said horizontal rail member having a pair of vertically spaced parallely aligned wall sections each of which has an opening therein which aligns with the opening in the other wall section, means for rigidly connecting the block member to the horizontal rail member through the vertical passage in the block head portion and through the openings in the wall sections of said rail member, a curved plate member located within the vertical rail member and bearing against one of the end walls thereof, said plate member having a central opening therein which aligns horizontally with the openings in the vertical end wall openings and with the horizontal passage in the block member base portion, and fastening means threadably engageable with the block member through the passage in the base portion thereof and insertable for threadable engagement through the openings in the vertical rail member end walls and the central opening in the curved plate member, said fastening means upon the tightening thereof applying tension forces to the plate member and compressive forces at the juncture of the horizontal and vertical rail members, assuring accurate and precise alignment of the parts and a firm connection therebetween.
Claim 3
Dependent Claim
75 words
A door construction of the character defined in claim 1, wherein the means rigidly interconnecting the block member to the horizontal rail member comprises a plurality of pin means drivably engageable therewith through penetration into and locking fitting contact with the vertical passage in the head portion of the block member and the horizontal rail member wall sections, thereby assuring relative immovability of the block member with respect to the horizontal rail member after assembly.
Claim 4
Dependent Claim
92 words
A door construction of the character defined in claim 1, wherein the head portion of the block member is shaped with inclined surfaces thereon surrounding the horizontal passage in said head portion, and the vertical rail member is formed to include on one end wall thereof spaced inwardly directed tapered lip sections and intermediate thereof a tongue section, said inclined surfaces on the block member head portion exerting upon tightening of the parts a crimping action upon the tongue section to effect a rapid alignment of the horizontal and vertical rail members.
Claim 5
Dependent Claim
48 words
A door construction of the character defined in claim 3, wherein the tongue section is generally T-shaped in vertical cross-section, and the arms thereof are engaged in crushing relation with the inclined surfaces of the head portion of the block member by the tensional and compressive forces applied.
Claim 6
Dependent Claim
98 words
A door construction of the character defined in claim 4, wherein the vertical rail member receives in slidable tight fitting relationship therewith an intermediate sash section, said sash section being of channel-like configuration when viewed in cross-section and having a pair of transversely spaced end walls and integral inwardly directed leg portions, the leg portions being received under the arms of the tongue section on the vertical rail and the end walls and leg portions Of said sash section at the juncture being formed with a groove which receives the tapered lip sections on the vertical rail member.
Claim 7
Dependent Claim
