DOOR OR LIKE CONSTRUCTION BACKGROUND OF THE INVENTION It is known in the art to which this invention pertains to provide a door or window structure made up of horizontal and vertical rail sections welded together or through bolted. A plurality of plates positioned interiorly of the two rail sections have been employed to anchor the sections one to the other by a series of welds. However, under certain operational conditions, the desired degree of right-angular alignment of the two sections was at all times not effected, with the result that the door or window did not slide properly, or in other words, the two sections did not mate with the requisite degree of preciseness with the supporting building structure. A poor fit thus resulted, often causing binding of the parts.

SUMMARY OF THE INVENTION The instant invention is directed to door constructions, exemplified by those of the butt hinge, offset and center hung type, embodying a plurality of rigidly interconnected vertical and horizontal rail sections desirably formed of extruded aluminum or alloys thereof. In accordance with this invention, the door or window structure during the assembly thereof, generally at the site of manufacture, incorporates in one of the horizontal rails and normally the bottom one, a precisely contoured connector member or corner block having a threaded opening in the base thereof and an upstanding passage through the yoke or head portion of the block, adapted to receive a pair of pins or like means forcefitted through the spaced legs of the horizontal rail section.

The horizontal and vertical rail sections during the extrusion thereof are provided with integral longitudinally extending generally T shaped protruberances designed to receive in mating relationship therewith an extruded strip or requisite length of glazing gasket material of elastomeric construction. The tongue or T shaped glazing leg on the vertical rail section abuts the base portion of the corner block, and within the channel-like vertical rail section a contoured or arcuatelyshaped plate member is located which is apertured to receive screw means or the like which affixes through an opening in the outer wall of the vertical rail to the horizontal rail.

In this manner, by cooperation of the plate member and corner block or connector member, the compressive force of the nut plate places the completed joint under tension, and a firm interlock is established between the inclined planes on the contoured block and T sections of the vertical rails, relatively rapid selfaligning effected, and further, a structurally sound and tight juncture of the vertical and horizontal rails thereof results from the relatively rapid self-aligning and precise positioning of the parts by the contoured corner block.-

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now first to FIG. 1 of the drawings, there is designated generally by the legend D a door construction embodying the novel concepts of this invention. As is shown, the exemplary center hung door structure comprises a pair of doors l0 and 12 mounted in the manner known to the art upon hinge means (not shown), although it is within the contemplation of this invention that the doors may be slidably mounted rather than swingably secured. The left and the

right doors

10 and 12 are of identical construction, and each includes a supporting

framework

14 and 16 comprised of

horizontal rails

18 and 20 and rigidly interconnected vertical rails or

stiles

22 and 24, the former being referred to in the art as hinge stiles and the latter lock stiles. As is also shown, in the illustrative embodiment each

door

10 and 12 is provided with a transversely extending center push bar 26, and pull handle means 28, the entirety as thus far described being in swingable relation with threshold means 30.

Referring now also to the other views of the drawings, the vertical rail or stile 22 in particular, and possibly also its transversely spaced and parallely aligned member 24, are generally rectangular when viewed in vertical cross-section and each is extrusion drawn or otherwise formed to provide an end wall 32, apertured as at 34, and integral with spaced

side walls

36 and 38 connecting with, as a part of the extrusion process, an inwardly facing end wall 40, passaged as at 42. The inner end wall 40 of the vertical stile 22 carries thereon, preferably shaped during extrusion, a pair of inwardly directed

lip sections

44 and 46 of generally tapered configuration intermediate of which is a tongue section 48 of generally T-shaped vertical crosssectional shape.

The wall 40 of the vertical stile 22m 24 through the opening 42 therein, which is horizontally aligned with opening 34 in the end wall 32, is sized to receive therethrough fastening means 50 threadably engaging a contoured connector or corner block member 52 provided with a horizontally located threaded opening 54 in base portion 56 of thecorner block 52. Also receiving the fastening means 50 is an arcuately shaped nut plate 58 passaged as at 60 and designed to exert tension applying forces to the wall 40 of the

vertical stile

22 or 24 and transfer the same to the tongue section 48 which is placed under compression by reason of its inclined plane configuration, thereby crimping or crushing the tongue or T-section 48 and assuring a firm interlock between the vertical and horizontal rail in a manner to be more fully described later.

The corner block or connector member 52, which preferably is of extruded aluminum or alloys thereof, has formed integral with its base portion 56 a yoke or head portion 62 vertically passaged as at 64 to receive in firm fitting relation a pair of

joint pins

66 and 68 which are driven through

apertures

70 and 72 in a generally T-shaped extruded section 74 formed on top wall 76 of the horizontal rail member 20 and an intermediate extruded wall section 78 which transversely extends between depending

leg sections

80 and 82.

Referring now particularly to FIGS. 1 and 3 of the drawings, there is slidably associated with the

vertical rail member

22 or 24 an intermediate sash member 84 of general channel-like configuration when viewed in cross-section as in FIG. 3. The sash member 84 is also of extruded aluminum, and as an integral structure is formed with transversely spaced end walls 86 and 88 and inwardly directed tongue-engaging

leg portions

90 and 92, the end wall and leg portion at the juncture thereof being grooved as at 94 and 96 to receive in slidable snug fitting relationship the inwardly disposed

lip sections

44 and 46 on the

vertical stile members

22 and 24. Also integral with the end wall portions 86 and 88 and generally parallely aligned with and transversely spaced from the

leg portions

90 and 92 is a pair of glazing gasket-receiving

arm portions

98 and 100 which grippingly engage the sealing gasket 102. As is known to the art, the gasket is formed of neoprene or other suitable elastomeric substance and embraces in air and fluid tight relation glazing material 104, which may be glass, plastic or panel.

The horizontal rail member is generally similarly configured, and as appears in FIG. 4, cooperates with an intermediate sash member 105 extruded of aluminum or suitable alloys thereof and formed to include opposed end wall portions 106 and 108 from which depend inwardly directed

leg portions

110 and 112 designed to grippingly engage the tongue section 74 on the horizontal rail member 20. The sash member 105, like the sash member 84, is provided with generally arcuately shaped gasket-receiving pockets or

arm portions

114 and 116 for tight fitting contact with gasket means 118. Seated in the gasket means is the glazing material 104.

A preferred method of assembly of the door construction ofthis invention will now be briefly described. With the parts generally positioned as in FIG. 6, the corner block or anchoring connector member 52 is located in slidable relationship with top wall 76, bottom wall 78 and upstanding horizontally spaced

side walls

122 and 124 of the horizontal rail member 20. As appears, after the positioning of the block member 52 with respect to the horizontal rail member 20, the vertical passage 64 has driven therein through the

apertures

70 and 72 in the horizontal rail member 20 a plurality of the

joint pins

66 and 68 to effect a firm securement therebetween. Subsequent thereto, or as a part of the initial assembly operation, the arcuately contoured nut plate 58 is affixed through fastening means 50, as by insertion of wrench means (not shown) through opening 34 in the vertical rail end wall 32 and into the corner block member 52, the nut plate 58 being in bearing re lation to the wall section 40 of the

vertical stile

22 or 24, thereby exerting tension upon the nut plate and applying compressive forces to particularly the tongue section 48 which is contoured to have inclined planar surfaces formed thereon. In this manner, a crimping or crushing force is exerted upon the tongue section, a firm interlock is assured, and a structurally sound and tight joint is accomplished, with automatic horizontal and vertical alignment with only one central fastening.

It is believed manifest from the description earlier given that the particular mode of assembly of the intermediate sash members and glazing gaskets need not be further undertaken.

Various modifications in the structures herein disclosed have been described, and these and other changes may of course be effected without departing from the spirit of the invention or the scope of the subjoined claims.
