6 Claims. ((11. 189-46) This invention relates to improved pilaster structures and hinge bracket assemblies in which the door supporting hinge brackets are rigidly secured to the jamb edge of the pilaster in cantilever suspension and without attachment to the side faces of the pilaster. This application is a continuation-in-part of my copending application Serial No. 696,864 filed November 15, 1957, now US. Patent 2,876,874 issued March 10, 1959, and a division of my copending application Serial No. 795,683 filed February 26, 1959.

Hinge brackets made in accordance with this invention are particularly designed for cantilever attachment to frame structures, posts and pilasters whose jamb edge is of relatively narrow width, and are particularly designed for attachment to the jam-b edge of hollow metal pilasters which measure only one to two inches or less in thickness, and which form the supporting uprights for interior cubicles, such as toilet and hospital cubicles, and the like.

A typical hollow metal pilaster with which the hinge brackets of this invention may be associated, may be formed by a pair of spaced metal facing sheets bonded to a reinforcing core of sound deadening insulation, and which present paired inturned flanges along the exposed vertical and horizontal edges thereof. The paired inturned flanges present a pair of outturned lip portions formed integral therewith and joined together by exteriorly applied spot welds to provide a rigid pilaster construction. Edging strips of semi-tubular cross section, and presenting a contoured facing portion and paired inturned lip portions, are telescoped over the outturned lip portions of the pilaster body to interlock therewith. The applied edging strips thus supply a finished appearance to the exposed vertical and horizontal edges of the pilaster.

The improved hinge brackets of this invention may be die cast or otherwise formed as integral units to present a laterally extending door supporting arm section on which the door is swingably mounted. These hinge brackets are designed to be mounted on the janr'b edge of a relatively thin pilaster by means which engage or interlock with a jamb portion of the pilaster or with associated parts applied to or built into the pilaster during its manufacture. Where the hinge bracket includes an exterior body section from which the arm supporting section laterally extends, the body section thereof is equipped with means to rigidly secure the same to a formed jamb portion of the pilaster and between the terminal ends of the contoured jamb facing portions thereof, and with the exposed outer face of the bracket body section in contour symmetry with the outer faces of the contoured jamb facing portions of the pilaster.

In one form of this invention, a steel locking channel may be secured to the fiat j amb portion of the pilaster body between the terminal ends of the contoured jamb facing portions thereof, and which is designed to interlock with a corresponding female formation on the rear face of the bracket body section.

In another form of this invention, the rear face of the bracket body section may be provided with a V-shaped groove designed to telescope over adjacent outturned lip portions of the pilaster body with the bracket body section rigidly locked thereto by one or more deforming wedges "ice driven between the outturned 'lip portions to thereby deform those sections of the outturned lip portions which are encased within the bracket body section.

All forms of this invention feature hinge brackets which are in architectural symmetry and harmony with the adjacent contoured jamb facing portions of the pilaster body, and with the exposed sections of the hinge bracket confined to the jamb edge of the mounting pilaster. The laterally extending door supporting arm sections of these hinge brackets present a pin-tle hole formed to receive a hinge pintle associated with a bracket counterpart applied to either the upper portion or lower portion of the mounted door. By the use of these hinge brackets, the pilaster is not defaced by bracket side flanges which telescope over the sides of the pilaster and secured thereto by bolts or screws as heretofore used, but on the contrary, the exposed surfaces of these hinge brackets are contoured in blended symmetry with the jamb edge of the pilaster to provide a door supporting structure of architectural harmony and beauty.

These improved pilaster structures and binge bracket assemblies are so constructed as to insure precise alignment of the upper and lower hinge brackets and accurate hanging of the door without field adjustment. These hinge brackets may be economically die cast or otherwise assembled as an integral unit at substantially less cost than door supporting hinge brackets heretofore made, can be attached to a floor supported or ceiling hung pilaster during manufacture thereof, and as mounted thereon, present an assembly which is substantially free of projections and crevices in which dirt would collect.

Other objects and advantages of this invention will become apparent as the disclosure proceeds.

Similar reference character refer to similar parts throughout the several views of the drawings and the specification.

All of the door supporting hinge brackets constructed in accordance with this invention are particularly designed for attachment to the jamb edge of hollow metal posts or pilasters which may be either floor supported as shown in FIG. 1 or ceiling supported as shown in H6. 2. These door supporting pilasters are particularly adapted for assembly into interior cubicles, such as hospital and toilet cubicles.

The floor supported pilaster 1 as shown in FIG. 1 and the ceiling hung pilaster 1 as shown in FIG. 2, and with which the door supporting hinge brackets of this invention are particularly adapted for attachment, comprise a pair of pilaster facing sheets 2"'2 formed from sheet metal or other strong sheet material, which together present inturned flanges 3-3 along the exposed vertical and horizontal edges thereof. Each pair of inturned flanges 33 incorporate outturned lip portions 4 which are secured together by suitable spot welds 4 exteriorly applied to the paired outturned lip portions at the crotch area between them as shown in FTGS. 4 and 9. Prior to spot welding together the paired inturned lip portions 4 to provide a rigid pilaster construction, a reinforcing and insulating core 5 is first adhesively bonded to the inside face of one of the pilaster facing sheets 2, and the exposed face of the reinforcing core is then coated with adhesive and the other facing sheet 2 then applied thereto. Pressure is then applied to the sandwich as thus formed to insure a firm adhesive bond between the reinforcing core 5 and the inside faces of the pilaster facing sheets 2-2. The reinforcing core 5 is desirably composed of a relatively hard, pilaster sheet bracing and sound deadening insulation packing, such as slabs of fibreglass, honeycomb fibreboard or other core material which is relatively light in weight, capable of deadening sound, and capable of bracing and supporting the pilaster facing sheets 2-2 to which the reinforcing core 5 is adhesi-vely bonded.

The exposed vertical and horizontal edges of the pilasters 1-1 are trimmed by means of edging strips 6 of semi-circular cross-section and similar in size and contour. Each edging strip 6 presents a face portion 6 of generally curvilinear form which terminates in inturned lip portions 7. The edging strips 6 are designed to be telescoped longitudinally over the outturned lip portions 4 of the pilaster facing sheets 2-2, so that the inturned lip portions 7 of the edging strip will interlock with and be firmly secured to the outturned lip portions 4 of the pilaster facing sheets 2--2 as shown in FIGS. 1, 2, 3 and 8.

During manufacture of the sheet metal panel facing sheets 2-2 of the

pilasters

1 and 1, suitable cut-outs, deformations or additions may be made in or to those areas of the inturned flanges 3 and outturned lip portions 4 to which the door supporting hinge brackets of this invention are to be applied, to thereby provide suitable seating faces and anchoring means for rigidly securing the selected hinge bracket to the jamb edge thereof, as more fully hereafter explained. All of the hinge brackets of this invention are particularly designed to be applied to the prepared areas of the inturned flanges 3 0f the panel facing sheets 22, either before the lip portions 4 of the panel facing sheets have been spot welded together, or after the reinforcing core 5 has been positioned between the panel facing sheets and the outturned lip portions 4 thereof welded together as heretofore explained.

The floor supported end of the pilaster 1 as shown in FIG. 1, and the ceiling supported end of the pilaster shown in FIG. 2, are suitably secured to the floor or ceiling Wall by suitable brackets and lag bolts as shown in FIGS. 1 and 2. The floor or ceiling supported end of the pilaster and associated wall securing means, are concealed within a trimming shoe 8 as shown in FIGS. 1 and 2 which snugly telescopes over the pilaster and snugly seats against the horizontal building wall to which the end of the supported pilaster is attached.

The door supporting hinge bracket G shown in FIGS. 3, 5, 6 and 7, is designed to be mounted on the jamb face of the

hollow metal pilaster

1 or 1 and to seat against the adjacent flange portions 17 of the pilaster body as shown in FIG. 4, and held thereto by a snap fastener in the form of a snap lock channel 54. The hinge bracket G may be die cast as an integral unit to provide a door supporting arm section 20 extending from a body section 50 which presents a curvilinear outer face 50 in contour conformity to the outer faces of the curvilinear face portions 6 of the upper and lower edging strips 6 applied to the pilaster body. The hinge bracket G may be used as an upper hinge bracket, or a lower door supporting hinge bracket, by providing a pintle hole 20' therein to receive an upper door hinging pintle, or a pintle hole 20" therein which supports a lower pintle on which the door is swingably supported.

The bracket body section 50 may present square cut ends 50 against which the terminal ends of the upper and lower edge moulding strips 6 are designed to abut, to thereby provide substantially flush and single line joints therebetween. The upper and lower ends of the body section 50 may also be provided with a tongue or a pair of spaced vertically extending studs 51 at one or both ends thereof which are designed to telescope into the adjacent end of the semi-tubular edge moulding strip 6.

The body section 50 also presents a pair of spaced rear facing portions 52 which define a vertically extending locking groove 53 therebetween, as shown in FIGS. 3 and 7. The locking groove 53 presents side ledge portions 53 designed to interlock with a snap-lock channel 54 which is first applied to the jamb face of the pilaster body as shown in FIG. 4. The spaced rear facing portions 52 of the bracket body section 50 are designed to flatly seat against the outside faces of the inturned flange portions 17 of the pilaster body when the bracket body section 59 has been pushed into locking relation with the snap-lock channel 54.

The snap-lock channel 54 presents a web portion 54' which seats against the outside faces of the inturned flange portions 17 of the pilaster body. The snap-lock channel 54 also presents side flanges 54" terminating in resilient curvilinear n'm portions 54 designed to snap into interlocking engagement with the side ledge portions 53' of the locking groove 53 formed in the rear face of the bracket body section 59. The web portion 54' of the snap-lock channel 54 is rigidly secured to an internal bracing plate 18 which seats against the inside faces of the inturned flange portions 17 of the pilaster body as shown in FIG. 4, and is secured thereto by suitable metal screws 18".

In manufacturing the pilasters 1 and 1' to support one or more of the hinge brackets G, the inturned flanges 3 of the pilaster facing sheets 22 are formed to provide the usual outturned lip portions 4 above and below the area where the hinge bracket G is to 'be applied, leaving lipless inturned flange portions 17 therebetween which provide a flat seat for the spaced seating portions 52 of the bracket body section 54). A sturdy bracing plate 18 is positioned adjacent the inside face of the inturned flange portion 17 of one of the pilaster facing sheets and secured as by spot welds 17 thereto. After the reinforcing core 5 has been adhesively bonded to this pilaster facing sheet 2, the companion pilaster facing sheet 2 is applied thereover and adhesively bonded to the adjacent face of the reinforcing core 5. The inturned lip portions 4- are then secured together by the application of a series of spot welds 4 in the crotch therebetween as shown in FIG. 4. The terminal ends 4 of the existing lip portions 4 are sufficiently spaced to permit the application of the body section 45 of the hinge bracket G to the inturned flange portions 17 therebetween. The inturned flange portions 17 of the second and companion pilaster facing sheet 2 may also be spot welded or screwed to the underlying bracing plate 18. The snap-lock channel 54 is then placed in seating position against the outside faces of the flange portions 17, and rigidly held in position by two or more metal screws 18 extending through the web portion 54 thereof and screwed into tapped holes provided in the internal reinforcing plate 18.

The bracket body section 59 is then applied by telescoping the locking groove 53 in the rear face thereof over the side flange portions 54" of the snap-lock channel 54 until the resilient curvilinear rim portions 54" thereof snap into interlocking engagement with the side ledge portions 53' of the locking groove. The spaced rear facing portions 52 of the body section will then snugly seat against the outside faces of the inturned flange portions 17 of the pilaster body.

The upper and lower moulding strips 6 are then telescoped over the outwardly flared lip portions 4 of the pilaster body as indicated in FIG. 3, and the terminal ends thereof placed in abutting relation to the square cut ends 50 of the bracket body section 50, and with the locking studs 51 snugly telescoped into the adjacent terminal end portion of the semi-tubular edging strip 50.

The hinge bracket G is thus rigidly and securely mounted on the jamb face of the pilaster by the snap-lock channel '54 whose resilient curvilinear rim portions 54" are in looking engagement with the side ledge portions 53" of the locking groove 53- extending vertically along the rear face of the bracket body section 541*. This bracket is further braced by the spaced rear facing portions 52 extending along the locking groove 53, and which snugly seat against the outside faces of the inturned flange portions 17 of the pilaster body. The hinge bracket G may be further rigidly fixed to the jamb face of the pilaster body by the provision of tongues'or studs 51. which project from the upper and lower ends of the bracket body section 50 and into the end of the adjacent semi-tubular edging strip 6, and with the three sides of each stud 51 in bracing relation to the inside faces of the curvilinear portion 6' and the inturned lip portion 7 of the edging strip 6, and the face or edge of the adjacent lip portion 4 of the pilaster.

As thus assembled, the curvilinear outer face 50' of the bracket body section St} is in streamlined symmetry with the outer curvilinear faces of the applied edging strips 6, with no bracket securing means exteriorly visible when the hinge bracket G is fully assembled on its supporting pilaster.

The door supporting hinge bracket H shown in FIGS. 8, 10, 11 and 12 comprises a body section 55 having a door supporting arm section 20 extending therefrom. The body section has a V-shaped locking groove 58 in the rear face thereof which is designed to telescope over the outturned lip portions 4 of the pilaster body as shown in FIG. 9, and to seat against the inturned flanges of the

hollow metal pilaster

1 or 1, and held thereto by a locking wedge 19. The hinge bracket H may be die cast as an integral unit, with its body section 55 shaped to present a curvilinear outer face 55 in contour conformity to the outer faces of the curvilinear face portions 6- of the upper and lower edging strips 6 locked to the outwardly flared lip portions 4 of the pilaster body. The hinge bracket H may be used as an upper hinge bracket, or a lower door supporting hinge bracket, by providing a pin-tle hole 20 therein to receive an upper door hinging pintle, or a pintle hole 2t) therein which supports a lower pintle on which the door is swingably supported.

The bracket body section 55 presents square cut ends 56 against which the terminal ends of the upper and lower edge moulding strips 6 are designed to abut, and to thereby provide substantially flush and single line joints therebetween. The body section 55 also presents a pair of spaced rear facing portions '57 which define a vertically extending V-shaped locking groove 58 therebetween as shown in FIGS. 8 and 12. The locking groove 58 presents inclined side face portions with which adjacent lip parts 4a4a of the pilaster body are designed to frictionally interlock. The locking groove 58 is defined between spaced rear facing portions 57 designed to flatly seat against the outside faces of the adjacent inturned flanges 3 of the pilaster body.

The lip parts 4a4a of the outturned lip portions 44 which extend into the V-shaped locking groove 58 of the bracket body section 55, are laterally expanded into frictional locking engagement with the side faces of the V-shaped locking groove 58 by one or more locking wedges 19 which are driven into the locking groove 58 through the open ends thereof. Each locking wedge 19 is shaped to deform and swedge the lip parts 4a4a into frictional locking engagement with the inclined inside faces of the adjacent rear facing portions 57 of the bracket body section. The deformation of the outwardly flared lip parts 4a4a may be facilitated by providing transverse cuts 4b-4b to separate the upper and lower ends of the outwardly flared lip parts 4a4a from the adjacent outwardly flared lip portions 44 of the pilaster body.

Each of the locking wedges 19 may be made from a steel strip of substantial thickness, and shaped to provide inclined side edges 19' as shown in FIG. 13. The insert end 19 of the locking wedge 19* is slightly tapered to facilitate insertion thereof into the V-shaped locking groove '58 of the bracket body section 55 as telescoped over the outwardly flared lip parts 4a4zz of the pilaster body. The locking wedge 19 is provided with side bulge portions 19" directly above the tapered end 19" thereof, which serve as camming anvils to further outflare the lip parts 4a4a into frictional locking engagement with the adjacent inclined side faces of the spaced rear facing portions 57 which define the V-shaped groove 58 of the bracket body section. The deformation of the outfl-ared lip parts ta-4a results from the spreading action exerted by the bulge portions 19" of the looking wedges 19' as. driven into the opposite ends of the V-shaped groove 58 of the applied bracket body section. The deformation of the lip par-ts 4a4a also serve to offset the ends of the lip parts 4a-4a with respect to the adjacent cut ends of the lip portions 4-4 of the pilaster body, and thereby prevent the possibility of vertical movement of the bracket body section 55 as locked to the lip parts 4a-4a by the locking wedges 19.

In manufacturing the pilaster .1 or 1 to support one or more of the hinge brackets H, a reinforcing core is adhesively bonded to the inside face of one of the panel facing sheets 2, and the companion panel facing sheet 2 is then adhesively bonded to the other side of the reinforcing core. Spot welds 4' are applied at spaced intervals to the outwardly flared lip portions 4 in the crotch area therebetween to provide a rigidly assembled pilaster body. Additional seam welds 40 may be applied to the crotch area of the lip parts 4a which is to be encased by the bracket body section 55. Transverse cuts 4b4b can then be made to separate the ends of the lip parts 4a-4a from the adjacent ends of the lip portions 4-4, the cuts 4b4b which define the ends of the lip parts 4a4a being spaced in conformity with the length of the bracket body section 55.

The hinge bracket H is then applied by telescoping the V-shaped locking groove 58 of its body section over the upper or lower'terminal ends of the lip portions 44, which terminate at both the upper end and the lower end of the jamb portion of the pilaster body, and then sliding the bracket body section 55 into telescoped position over the lip parts 4a4a where the hinge bracket is to be fixed in position. A locking wedge 19, shaped as shown in FIG. 13, is then inserted into one end of the V-shaped groove 58, and preferably a similar locking wedge 19 is also inserted through the other end of the V-shaped locking groove 58. Both locking Wedges 19 may be simultaneously driven into the groove 58 of the bracket body section 55 so that the located position of the bracket body section is not disturbed.

As the upper and lower locking wedges 19 are driven into the V-shaped groove 58 of the body section, the encased lip parts 4a-4a are swedged outwardly into frictional locking engagement with the inner inclined side faces of the spaced rear facing portions 57 which define the V-shaped groove 58, thereby rigidly locking the bracket body section to the pilaster body, and with the spaced rear face portions 57 thereof in firm seating position against the outside faces of the adjacent inturned flanges 3 of the pilaster body. The upper and lower edge moulding strips 6 are then telescoped over the outwardly fiared lip portions 4 of the pilaster body as indicated in FIG. 8, and the terminal ends thereof placed in abutting relation to the square cut ends 56 of the bracket body section 55. Since the inturned lip portion 7 of the edge moulding strips 6 interlock with the outturned lip portions 4--4 of the pilaster body with substantial friction, the terminal ends of the moulding strips 6 which abut the square cut ends 56 of the bracket body section also provide support for the bracket body section 55 which further prevents any longitudinal movement of the hinge bracket H along the jamb portion of the pilaster.

As thus assembled, the hinge bracket H is rigidly and immovably locked to the jamb portion of the

pilaster

1 or 1, with the curvilinear outer face 55' of the bracket body section 55 in streamline symmetry with the outer curvilinear faces of the applied edging strips, providing flush single line joints therebetween as shown in FIG. 8, and with no bracket securing means exteriorly visible.

The hinge brackets made in accordance with this invention, may be provided with studs, wings or tongues which project from the ends of the body section and designed to interlock with the adjacent terminal ends of jamb edge mouldings, such as the hinge bracket G shown in FIG. 3. The hinge bracket G shown in FIG. 3, and hinge bracket H shown in FIG. 8, normally require a pilaster equipped with slidable edge moulding strips which may be slidably telescoped over the end studs 51,

or end wings or end tongues, or the ends of the wedges 19 projecting from the ends of the bracket body section.

It will also be appreciated that a bracket of the type similar to type G shown in FIG. 3, may also be applied to a pilaster having a fixed jamb face moulding portions 6, by eliminating the end studs 51 from the body section 50 of the hinge bracket G to thereby provide square cut ends, and by securing the snap lock channel 54 as by metal screws 18" to the bracing plate 18 as shown in FIG. 4, and with the spaced rear face portions 52 of the bracket body section 56 seating against the complementary inturned flange portions 3-3 of this pilaster.

It will be appreciated by those skilled in the art, that certain parts associated with one or more of the hinge brackets of this invention may be interchangeably applied and substituted for corresponding parts of other hinge brackets as above disclosed. For example, the insert studs 51 associated with the bracket G as shown in FIG. 3, may also be applied to the upper and lower ends of the body section 55 of the hinge bracket H shown in FIG. 8.

It will be particularly noted that all of the hinge brackets of this invention are directly supported from the jamb portion of a pilaster body, and do not overlap the side panel facing sheets of the pilaster body, and are particularly designed to be rigidly secured to the jamb edge portion of relatively thin pilaster bodies which may measure only one inch in thickness. The door supporting hinge and pilaster structures of this invention present an assembly wherein the exterior faces of the hinge brackets are in contoured symmetry with the ex posed faces of the pilaster edge moulding strips 6, and as assembled, present fine line butt joints therebetween which are scarcely discernible, and wherein the hinge bracket is securely locked and held in fixed position.

Pilaster structures and hinge bracket assemblies made in accordance with this invention feature the elimination of bracket side flanges and other projections heretofore used to secure the hinge bracket to the pilaster, and which provide areas for the collection of dirt and foreign matter which cannot be readily removed. The hinge brackets of this invention can be cast or formed in one piece, at substantially less cost than door supporting hinge brackets heretofore made and used, and can be mounted on the jamb edge of the pilaster at the factory in precise door supporting alignment, and with less labor and less cost than the pilaster and hinge bracket assemblies heretofore made and used. The necessary modifications to the jamb edge of the pilaster bodies can be accomplished in accord ance with this invention at minimum cost when cutting and fabricating the panel facing sheets, or during assembly of the pilaster body.

While certain novel features of this invention have been disclosed herein and are pointed out in the claims, it will be understood that various omissions, substitutions, and changes may be made by those skilled in the art without departing from the spirit of this invention.
