i DOOR MOUNTING ASSEMBLY Kenneth Johnson, Kensington, and Walter J. Mac-= Earlane, New Britain, Conn, assignors'toThe Stanley Works, New Britain, Conn a corporation of Connecticut f; Filed Sept. 1, 1959, Ser. No. 837,476 I e 6 Claims. "(Cl; 20 -16) The present iinvention relates toa new and improved type ofdo'ormounting especially adapted for use in resi- 'lheinvention is concerned more particularly with a novel arrangement for disposing a doorrelative to a door opening and to new and improved handware'for' use in combination therewith.

The present application is a continuation-impart of our prioryapplication Serial No -796,826, filed March 3, 1959 nowabandoned. T l t a I The conventional way of mounting swinging doors in homes and other types-lot buildings, is tofirst frame a; .1 door opening with a header and jambs and then trim the l at door so that itwill fit fairly closely within the frame opening with the edges of the door enclosed by the frame.

The door isnsually mounted in the frame by use of conventional butt hinges whose leaves are recessed in one edge of the door and adjacent jamb. The door is'usually held in closed position by a latch. mechanism recessed in the opposite edge of the door and a keeper recessed I, in the adjacent jamb. Such conventional door mounting arrangements are relatively expensive to manufacture and install, since it entails the making of a door frame which usually is a composite; of several members frequently fformedof wood and including stops, moldings and other decorative elements for finishingthe edge ofthe opening which have to :be fitted to the door opening andper- 'man'en-tly secured thereto. Also, after the door frame has been fitted and installed, it; then becomes necessary to accurately dimension the door so that it will fit relatively closely Wlhhll'llhCf-GODI opening andznormally this has to be donewat the place of installation because of dirnen-.

mounting arrangement having many advantages from a decorative standpoint and including the advantage of using completely prefinished doors.

' Another aim of the invention, is to provide a novel set of hardware for use in combination with.,the door and a door opening which 'is easy to install and assemble and which is decorativeinappearance.

" Other objects will be inpart obvious and in part pointed out morein detail hereinafter.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereafter set] forth and the scope of the application of which will be indicated in the'appended claims In the-drawings: U e FIG. 1 is a fragmentary perspective view of a wall and a door mounted thereon in accordance with the inveno FIG. 2 is a fragmentary front view of thedoor and wall assembly with the door opening shown in dotted lines; 1 FIG. 3 is an enlarged fragmentary cross-sectional view o fone door edge and side of the door opening with the hinge mounted in fully exposed position;

FIG. 10 is a view similar to' FIG. 4 showing a modified form ofthe hinge for use with doors of reduced sional variations which usually occur during the installaand the knuckles of the hinge -plates are interfitted to permit replacement of the hinge pins. In addition, as l mentioned above, the. door has to be provided with a "conventional door latch wherein the latch mechanism is recessed in one edge portion of the door and a cooperating keeper and strike plate is recessed intothe adjacent ation of thetdoor and door frame. A fter'the door has been fitted to thedoor frame it is vthen necessary to ac- .curatelymortise one edge of the door and the correspondingj-amb of the door frame for installation of the hinges. To hang the door it is the usual practice to disassemble I cealed position; and

thickness, the hinge being mounted in the partially con- .FIGJll is a perspective view of the hinge shown in FIG.1O with thedoor and wall in phantom,,the door being. in fully open position. I Referring to the drawings and particularly to FIGS. l, sZ -and 5 thereof, there is shown a building wall- 10 t provided with a rectangular opening or passageway 12.

f the hinges and secure the individual hinge plates inthe' T mortised recesses of the door edge and iamb, respectively, following which the door is placed in the door opening jamb of the doorfframe. All of these operations entail expensive andtime consuming hand. operations which I greatly add to. the'costof thejlconstruction and in addition there are certain other disadvantages, suchas the fact that thedoor cannot be completely fabricated or prefinished prior to installation andin the event of. subsequent warpage or.- shrinkage of the door or door frame members, the door may stick or fit so poorly in the door The aim of the present inventionis to providea new type. of door mounting which greatly reduces the cost ofmanufactureand assembly, both with. respect to the finishing or framing of the door opening .and with respect to thedimensioning of the door and the steps required to mount the door. t

llncluded in this taint is the provision of a new door Unlike conventional door. installations, the door14 does not fit within the opening 12 but instead is disposed paral; lel to the outer surface of the wall 10 externally of the I door opening 12 and is dimensioned so that it extends beyond the top and side edges of the door opening and so that it overlies both the opening 12 and the portion of the wall surrounding the opening. The door is swing ingly mounted on the exterior surface of the wall 10 by means'of hinges 16, which will be described in more'detail hereinafter. Since the door does not have to be fitted within the door opening 12, it can be completely prefrabricated and finished by the fabricator of the door and no further treatment is required at the time of installation.

When utilizing the door mounting of the present invention, it is unnecessary to frame the door opening 12 for, as best shown in FIGS. 3, 4 and 5, the surface of the sides of the door opening can be merely a continuation of the finish surface of the wall. Normally, the wall will contain one or more studs 18 which are disposed atop- ,positesides of the door opening and this may be covered with plaster, or wall bo'ard, etc. denoted at 20 which is the same as the surface coating of thewall. [[n any.event, the surface of the wall surrounding the opening 12 is preferably left planar and flush with the remaining surface Patented Sept. 3, 1963 I .3 of the wall as shown and ornamental moldings and the like are omitted.

As previously stated, the door 14 is mounted on the external surface of the wall by means of the hinges 16 so that when the door is in closed position it covers the door opening 12 and also the portions of the wall surrounding the opening 12. The door may be retained in the closed position by means of a releasable latch 22 which is recessed into the wall at the side of the opening opposite from the hinges for cooperation with a keeper assembly 24 mounted on the edge of the door. A decorative handle 26 may be provided on the outer face of the door for convenience in opening and closing the door.

The hinges 16 are of new and improved form especially designed for use in-mounting the door in the manner described. The details of the hinge are best shown in FIGS. 6, 7 and 9 of the drawings. Each hinge includes one leaf 30 which is a flat leaf having a plurality of symmetracially spaced rolled knuckles 32 along one edge. The leaf 30 is adapted to be mounted on the edge of the door on the surface thereof without being recessed as indicated in FIGS. 3, 4 and 5. The rolled knuckles 32 are olfset from the plane of the leaf 30 and have aligned bores 31 whose axes are similarly offset from the longitudinal centerline of the leaf 30. Thus the knuckles 32 will not interfere with the fiush mounting of the leaf 30 on the surface of the edge of the door even though the knuckles 32 do not project outwardly beyond the corner or outer face of the door. The second leaf of the hinge 16 comprises a generally L-shaped plate 34 which also is provided with symmetrically arranged rolled knuckles 36 intended to interfit with the rolled knuckles 32 of the first leaf 30. The inner leg 38 of the hinge plate 34 is adapted to be mounted on the surface of the wall 10 and the outer leg 39 extends outwardly at right angles thereto and parallel to the first hinge leaf 30 when the door is in closed position. The centerline of the rolled knuekles36 and the aligned bores 37 thereof is substantially in alignment with the longitudinal centerline of the outer leg 39, this being accomplished by a slight bend in the leg 39 as indicated at 40. As a result of the central disposition of the knuckles 36, it is possible to assemble the hinge with the L-shaped leaf 34 extending outwardly away from the door opening and exposed adjacent the edge of the door as shown in FIGS. 3 and 5, or to assemble the hinge leaf so that the inner leg 38 extends in the opposite direction toward the door opening so as to be concealed by the door as shown in FIG. 4 of the drawings. Since the operation of the hinge is the same in either case, the assembly of the hinge with the leaf 34 extending in either a left-hand or a right-hand direction will be determined in most instances by the appearance which is desired by the user. Another consideration is that with the hinge assembled as shown in FIGS. 3 and 5, it is somewhat easier to attach the hinge to the wall, since the hinge can be attached with the door in closed position. Another factor which must be considered is the availability of studding for receiving the wood screws 42 (shown in dotted lines) for as indicated by comparison of FIGS. 3 and 4 of the drawings, additional or wider studding is required when the hinge is assembled with the leg 38 extending outwardly of the door opening.

In order to assemble the hinge in either a left-hand or right-hand'direction, all that is necessary is to pull the pintle 44 which is seated in the bores of the

knuckles

32 and 36 and then reverse the hinge leaf 34 following which the pintle 44 is re-inserted. The pintle 44 preferably is provided with a split retaining ring 46 which engages in the tapered or convexly curved lower portion of the bore of the uppehmost knuckles of the hinge leaf- 30 as disclosed in the Morse Patent No. 2,154,860 which prevents the pintle from rising during normal usage of the door. The pintle can readily be disengaged from the knuckles by exerting a force on the inner end thereof by means of a nail or pointed tool inserted through the opening 50 in the decorative tip 52, which is-threadably secured in the bore of the bottom knuckle of the hinge leaf 30.

In the event that the hinge 16 is to be secured to the opposite edge of the door 14 so as to cause the door to swing in the opposite direction, the leaf 30 is inverted and in that case it is preferred to reverse the position of the decorative tip 52 so that it will still be in the lowermost knuckle of the hinge. As will be noted in the cross-sectional view of the knuckles shown in FIG. 9 of the drawings, the uppermost knuckle of the leaf 30 is threaded in the same manner as the bottom knuckle so that it can also receive the decorative tip 52. The deco rative tip 52 is provided with a slot 54 so that it can be conveniently rotated by use of a screw driver or other turning tool when it is desired to remove the tip 52 from one end knuckle and replace it in the other. The bore of the lowermost knuckle is also tapered or convexly curved at its inner end for cooperation with the retaining ring 46 of the pin 44. The pin 44 may be inserted from either end and is preferably positioned in the bores of the knuckles so that its head is at the top of the assembled hinge. Thus it will be apparent that by reversing the tip 52 and insenting the pin 44 from the opposite end, the assembled hirnge when placed on the opposite edge of the door will still have the decorative tip at the bottom and the pin will he treated from the top. When the hinge is applied to the left-hand edge of the door, the leaf 34 may be assembled with its leg 38 extending away from the opening 12 and in exposed position or extending toward the opening 12 and concealed in just the same way as explained in connection with the mounting on the opposite edge of the door.

The modified hinge 116 shown in FIGS. 10 and 11 lot the drawings, is similar to the hinge 16 just described and includes an L-shaped hinge plate 134 which is like the plate 34 except that the leg 139 is of shorter length so as to reduce the dimension or distance between the knuckles 136 and the inner leg 138. The removable pintle 144 and the decorative tip 152 correspond to the pintle 44 and tip 52 previously described. The second hinge plate differs from the plate 30 by being provided with a night-angled extension 131 thus making it L-shaped in cross section. The plate 130 is dimensioned so that when the hinge is assembled for mounting in the partially concealed lposition, the

plates

130 and 134 will be disposed in nesting relationship and with the

ends

133, 135 in alignment.

As shown in FIGS. 10 and 11, the modified hinge 116 is intended for use with doors of relatively thin cross section or relatively small thickness. In this embodiment, the door leaf 130 extends around the inner corner of the door 114 and is secured to the door by screws 118 fastened to the inner surface of the door instead of to the end surface. As shown in FIG. 10, the leaf 134 is attached to the wall 110 by screws 142. It will he understood that as in the case of the hinge 16 previously described the pintle 14 and tip 152 may be removed to permit the leaf 134 to be reversed for attachment to the wall in an exposed position in the manner illustrated in FIGS. 3 and 5 of the drawings.

As illustrated in FIG. 11 of the drawings, the disposition of the

knuckles

136 and 132 in an offset relationship .to the

legs

131 and 138 permits the door to be opened a lfllll]. without striking the surface of the well 110.

The latch 22 comprises a [frame 54 which is recessed in an opening 56 provided in the wall 10 for this purpose and also includes an escutcheon plate or outer housing of L-sh'aped cross section which covers the opening 56 and extends about the corner of the door wall opening asbest shown in FIG. 5 of the drawings. The latch 22 includes a generally U-shaped bolt 60 which is pivoted on the frame at 62 and which is biased to open or closed position by a spring 64 mounted on the plunger 66. The
