COMPLETE PATENT SPECIFICATION FOR THE INVENTION ENTITLED IMPROVEMENTS IN OR RELATING TO DOOR ASSEMBLIES The following statement is a full description of the invention including the best method of performing it known to us: -2- This invention relates to an improved door or window assembly particularly for installation in an accommodating aperture such as a doorway or window way in a wall of a building, ll. f l 1- invention is primarily but not exclusively concerned with tilt-type doors wherein opposed side edges of a door panel may be pivotally attached to adjacent sides of the doorway in such a manner that the panel may be pivoted or tilted upwardly to open the doorway for access and pivoted oooO downwardly to close the doorway when required. Such doors .00, 9 o Do are usefully employed in building structures such as 0 garages, warehouses and factories.

Hitherto tilt--ype doors of the kind described 00 15 above have been disadvantageous in that it was necessary to 0 O manufacture a custom made door to be installed in each o individual opening. Thus in relation to installation it was necessary to attach the door panel to opposed doorway uprights or jambs which were usually installed in the doorway during construction of the building structure. This necessitated accurate measurement of the width and height of the opening and thus conventional tilt type doors were usually of different sizes and shape to accommodate variation in doorways and in particular brick surrounds.

The time spent in accurately measuring a doorway or door opening is a costly limiting factor both in regard to the price of installation of the finished door construction or end product and the effectiveness in operation of the tilt

A

i i I-Y -urr -3type door. This problem is especially emphasised if the installation site is a long way from the factory where the doors are fabricated.

It will also be appreciated that in some cases it was necessary to especially construct or machine timber jambs to the opposed sides of the doorway or door opening and this aspect also had a skyrocketing effect on installation cost. A further subsidiary problem of convention tilt type doors was the difficulty of obtaining an effective seal between the side edges of the door panel and an associated jamb or upright.

It is an object of the invention to provide a door or window eItr assembly particularly of the tilt type which alleviates the abovementioned disadvantages of the prior art.

A door or window assembly according to the invention 4 4t comprises a pair of opposed jambs, each having a substantially quadrilateral cross-section and including a longitudinally extending recess on at least two sides, each said recess including a pair of opposed longitudinal flanges extending ''2b inwardly partially across the open face of said recess; attachment mea. for attaching said jambs to opposed sides Sof said opening to form a support for a door or window of predetermined width, said attachment means each including a head slidably retained in one of said recesses of said jambs and a body portion extending outwardly of the flanges of said recess and adapted to enable said jambs to be rigidly attached to said -4opening; bracket means for pivotally supporting a door or window; and fastener means for adjustably engaging said bracket means with said jambs, said fastener means each comprising a head slidably engaging the inner surfaces of the flanges of another of said recesses of said jambs and a body portion extending outwardly of said flanges whereby said brackets may be adjustably and frictionally engaged with said jambs by retaining means associated with each said body portion.

a a a tohe-eareer Theb pArc may hP n a y suitable type and may comprise screws, pop rivets or oth appropriate fasteners. The spacers may be discarde when the door assembly is located in the doorway fo installation.

In step the door assem y as described above may be transported to the inst ation site with a suitable operating mechanism fitte or alternatively the operating mechanism may be tra ported separately and attached to the 0o 0 door assembly o site.

I step the jambs may still be connected to the door nel and attached to the sides of the doorway in fCpral different locations.

TLhu In a preferred embodiment of the invention the S. 15 jambs may be located adjacent as associated side surface of o o the doorway or be located behind the side surface and adjacent to or abutting a rear surface of the doorway. The w* doorway may be already constructed or an existing doorway or it may still be incomplete as will be apparent from the description hereinafter..

The jambs may be attached to the doorway in any suitable means in regard to the method of the invention. In one form there may be provided the aforementioned attachment members which may be adjustable brackets wherein the bracket may be fitted to the jamb by one or more captive bolts which may be located at any position over the full length of the jamb. In this arrangement the captive bolts having a head -6and a shank may be located in an associated elongate groove with the head thereof being placed within the confines of the groove and the shank which is usually threaded extending outwardly therefrom.

The adjustable bracket is suitably formed of two plate portions extending at right angles to each other with elongate slots located in each plate portion. The threaded end of the captive bolt may be inserted through tne slot in Sone plate portion and retained in position by an dppropriate 0 nut. The other plate portion may be bolted to the rear .0 o 0 a surface of the doorway. Thus in this embodiment each jamb 0 o may be attached to the doorway abutting the rear surface ft Q -f o Sthereof.

In another embodiment as described above each jamb may be attached to an adjacent side surface of the doorway oO with the shank of the captive bolt as described above being S retained within a mating socket in the brickwork. In this arrangement the shank may be secured in place by bricking or placing bricks around the exposed shank so that it is embedded in the side of the doorway.

In another variation there may be provided alternative securing means other than the adjustable bracket previously described. Thus there may be provided a wire fixing bracket having opposed resilient legs at one end q which may be compressed inwardly and retained in the elongate groove by virtue of their outward bias. The wire bracket may have at its other end a loop portion which may i- j .i -7be embedded in the surrounding brickwork as described above in the preceding paragraph.

In another embodiment the securing means may comprise a metal strap which is suitably serrated and having a head portion engageable in the captive groove of the jamb. In this arrangement the strap may again be embedded in the surround brickwork or between adjacent bricks as described above.

In a preferred embodiment of -the inipn+-nnn t-h o 10 assembly of jambs and door panel may be stood in the dopr way o still interconnected by the connection means or s cer means and the jambs attached to the sides of the orway as a 00 0 °4 described previously. The operating chanism comprising an assembly of top support bracket nd linkage arms with the 00 c oo 15 usual spring omitted may en be attached to the assembly a o while the spacers a estill intact. The spacers may be removed after e assembly has bee lifted into position and o"o the spr then attached to the top support bracket and a nooo r1n r an _hnrJnq hrarkpi- Reference may now be made to a preferred embodiment of the invention as shown in the attached drawings wherein:- FIG 1 is an exploded perspective view of a door assembly constructed in accordance with the invention; FIG 2 is a top plan view of the assembly shown in FIG 1; FIG 3A, 3B and 3C show various alternative locations for the jambs of the doorway assembly of the r 0 0000 O ~iOO S0 00I 0 S0 0 oo 0 a0 0 00 00 o 00 00 0 000 01 0 0 3 0 0 *0 00000 03 0 00*0 000* invention relative to the sides of the doorway; FIG 4 is a perspective view of a suitable securing means for the jamb relative to FIG 3B; FIG 5 is a perspective view of an alternative securing means for the jamb relative to FIG 3B; FIG 6 is a sectional view of a doorway assembly using the securing means of FIG FIG 7 is a top plan view of the doorway assembly shown in FIG 6; 10 FIG 8 is a view of yet another alternative securing means to that shown in FIG 5 or FIG 7; FIG 9 is a cross-sectional view of a jamb of alternative shape to that shown in FIGS 1-8; FIG 10 is a perspective view of the jamb of FIG 9 15 located behind a doorway in a similar manner to that shown in FIG 1; FIG 11 is a view similar to that shown in FIG 9 showing a captive bolt interconnecting the jamb to a stop plate.

The doorway assembly shown in FIGS 1-2 includes jambs 11 having elongate grooves 12, 13 and 14. There is also shown captive bolts 15 having heads 16 slidably received in grooves 12 and threaded shanks 17 extending outwardly therefrom. There is also indicated angle brackets 18 having plate portions 19 and 20 extending at right angles to each other. There is also provided elongate slot 21 located in plate portion 19 and elongate slot 22 located in -8invention relative to the sides of the doorway; FIG 4 is a perspective view of a suitable securing means for the jamb relative to FIG 3B; FIG 5 is a perspective view of an alternative securing means for the jamb relative to FIG 3B; FIG 6 is a sectional view of a doorway assembly using the securing means of FIG FIG 7 is a top plan view of the doorway assembly shown in FIG 6; 10 FIG 8 is a view of yet another alternative securing means to that shown in FIG 5 or FIG 7; S" FIG 9 is a cross-sectional view of a jamb of QoI alternative shape to that shown in FIGS 1-8; FIG 10 is a perspective view of the jamb of FIG 9 0 ooo 15 located behind a doorway in a similar manner to that shown I in FIG 1; i °FIG 11 is a view similar to that shown in FIG 9 showing a captive bolt interconnecting the jamb to a stop Io, plate.

The doorway assembly shown in FIGS 1-2 includes jambs 11 having elongate grooves 12, 13 and 14. There is also shown captive bolts 15 having heads 16 slidably received in grooves 12 and threaded shanks 17 extending outwardly therefrom. There is also indicated angle brackets 18 having plate portions 19 and 20 extending at right angles to each other. There is also provided elongate slot 21 located in plate portion 19 and elongate slot 22 located in plate portion 20 as shown. There is also shown nuts 16A which attach plate portion 19 of bracket 18 to bolt 15 as shown. Also shown is doorway 22 having opposed side surfaces 23, rear surface 24 and front surface 25. Doorway 22 is bounded by walls 26 as shown.

Also shown are top door panel installation brackets 27 for attachment to bolts 28 which have head portions 29 located in accommodating grooves 13 and outwardly extending threaded shanks 28A. Brackets 27 are retained in place by 0 nuts 30 which engage with shanks 28A. Shanks 28A each extend through slots 31 located in plate portion 32 of *8 8 8: bracket 27. There is also provided plate portion 33 of o a bracket 27 which extends rearwardly as shown.

There is also shown bottom installation brackets 34 ou 15 having angled plate portions 35 and 36. Plate portion includes aperture 37 for anchoring of spring 38 which is attached to top linkage arm 39 at 40. There is also shown 88 nut 38A which attaches plate portion 36 to bolt 28 through aperture 36A. Also shown is bottom linkage arm 41 pivotally attached to support plate 43 at 44. Support plate 43 is rigidly attached to door panel 45. Top linkage arm 39 is also pivotally attached to door panel 45 at 46. Door panel i includes surround frame 47 and panel portion 48. Top linkage arm 40 is pivotally attached to bracket 27 at 27A.

Plate portions 20 of angle brackets 18 are attached by bolts and nuts 20B to rear surface 24 of brick wall 26.

The operation of linkage arms 39 and 41 and spring :L i i 38 is the same as in a conventional tilt door mechanism and hence need not be repeated here. However, the door panel is shown in the closed position for convenience.

Thus in use plumbing and levelling of jambs 11 and door panel 45 is a simple matter by the use of adjustable brackets 18 as described. The bolts 15 may be located at any position over the full length of the jambs 11 and this allows the installer unlimited scope for selecting the most appropriate location for installation brackets. The slots 0 21 and 22 in angle brackets 18 provide for appropriate adjustment away from wall 26 of jambs 11. In this case an oo advantage is obtained in that variations in wall 00 00 o~oo construction or surface may be taken into account in the event of distortions such as rough or uneven brickwork on 15 the wall surface not being strictly level. To cover any Soo o .o gaps created by these distortions moulding cement or 6 building sealant may be used.

o *0 000.: After installation of jambs 11 to doorway 22 as described above the operating mechanism of bracket 27, 0000 linkage arms 39 and 41 and spring 38 may be attached to the door panel 45 to predetermined factory drilled holes (not shown). The operating mechanism may be preadjusted to suit the door size.

Should the operating mechanism as described above require adjustment during or after installation, it becomes a simple matter of adjustment by loosening bolts 28 in grooves 13 and relocating to the desired new position. The -11same of course can be said for adjustment of bolts 15 in grooves 12. This is in contrast to conventional tilt door assemblies wherein it was necessary when adjustment was required to form a new fixing or installation aperture and in some cases the necessary adjustment could not be made because the position of the new fixing or installation aperture would interfere with the previous aperture.

The invention provides for infinite adjustment I settings and also takes away the necessity of using a 10 specialist door fitter. It also allows for an untrained Q S a 0 person who can follow instructions to purchase a door and o instal it themselves without difficulty.

S 9 o Each groove 12, 13 and 14 is provided with overhanging portions or lips 49 to slidably retain the head 1.15 portions 16 and 29 of bolts 15 and 28 therein for purposes S..s of adjustment.

96 Groove 14 is provided for the retention of a ~weather strip or elongate seal 50 and this provides another advantage of the invention in that this allows for tilt rit doors when constructed by the method of the invention to provide for proper sealing with respect to the side edges of door panel 45 in conjunction with jambs 11. This feature has been missing fromin prior art tilt doors.

In FIG 3! jambs 11 are shown attached to rear surfaces 24 of wall 26 as described above in FIGS 1-2.

However, in contrast in FIG 3B the jambs 11 if desired may be abutted or located adjacent to the centre portion of side -;j

A.

-12- 0000 0 0 000 oeo 00 0 o 0 00 801 0 (0 00 o e, nn 00 000"0 000 surfaces 23 of doorway 22 and be attached thereto directly by bolts 51. Alternatively in FIG 3C jambs 11 may be attached to side surfaces 23 of doorway 22 substantially flush with front surface 25. In this embodiment angle brackets 18 maybe used to attach jambs 11 to side surfaces 23 of doorway 22 as described above in FIGS 1-2.

It will be appreciated from a review of FIGS 3A, 3B and 3C that by varying the dimensions of exposed jambs 11 and manufacturing door panels in accordance with stock 10 supplies in the factory modular increments in both height and width may be obtained. This means that a particular 0 panel and jamb assembly may be installed in a wide variety of doorways or openings suitably up to 100mm wider than the assembly. Installation of the assembly becomes a very simple manner of placing the assembly behind or within the opening as shown.

In FIG A there is shown jamb 11 with bolt 15 being retained in groove 12 as previously described. In this case however shank 17 extends directly into the side surface 23 0 of doorway 22 and can be inserted between bricks 52 and be retained therein by cement. Suitably in this embodiment the door panel 45 with jambs 11 secured thereto is set up on a temporary base (not shown) at desired height and is then plumbed and levelled with props to hold the assembly securely. Subsequently a first row of bricks may be laid firmly against the jamb 11 and the brick holiing bolt 15 is placed into channel 12 and lowered onto bricks 52 and -13secured to the jamb 11 by a flat nut 53. This procedure may be repeated as often as may be required.

This "bricking in" procedure has advantages in that it does away with drilling, screwing and other expansion fitting methods and results in a secure method of fixing to bricks or blocks. The adjustment procedure as detailed above can be carried out after the normal brick curing period.

In FIG 5 there is shown a metal strap 54 having 10 serrated shank 55 and head portion 56 for retention in groove 12 of jamb 11. There is also shown intermediate 4 a portion 57. The strap may be fixed in place between mortar 0 00 o0 or cement layers 58 which surround each brick 52 as shown in FIGS 6-7.

In FIG 8 there is a resilient clip 59 having a pair o oof opposed U shaped legs 60 for retention within groove 12 S: of jamb 11. There also may be provided loop portion 61 for enclosing one or more bricks 52 as desired and it will be 0o appreciated that clip 59 provides a viable alternative to bolt 15 or metal strap 54 in relation to the "bricking in" procedure as described above.

It will also be appreciated that the invention may be applicable to the installation of window assemblies comprising opposed uprights and interposed window panels.

It will also be appreciated that the invention includes within its scope the jambs per se.

In FIGS 9-11 there is shown an alternative type of -14jamb 62 for use in the present invention including an elongate groove 63 having an enlarged portion 64 which may accommodate a captive washer 65 as well as head 66 of captive bolt 67 which has shank 68 engaging with nut 69 in the same manner as previously described. There is also shown groove 71 for accommodating a weather seal (not shown) and groove 70 for engaging with plate component 19 of angle bracket 18 in a similar manner to that shown in FIG i.

Groove 71 may also engage with an outwardly extending projection 75 hav.- Lip 72 of a stop plate 73 which is 0J S• engageable with jamb 62 near the base thereof.

0 The provision of enlarged portion 64 of groove 63 0 S as well as enlarged portion 74 of groove 70 enables both 0 Do o grooves 63 and 70 to accommodate a captive washer of the type as designated by reference numeral 65 which provides an improved performance under load to the assembly shown in FIG 1.

Groove 63 may engage with plate component 32 of top angle bracket 27 in a similar manner to that embodiment °'OQ described above in FIG 1.

20 The provision of outwardly extending portion 76 of stop plate 73 functions to engage with the door panel 45 in the closed position and engage with a spring loaded catch (not shown) attached to the door panel and thus lock the door panel in the closed position. Upon rotation of the conventional door panel handle (not shown) the spring loaded catch may be withdrawn from engagement with portion 76 of L i 4 stop plate 73 and thus the door panel may be opened.
