United States Patent 9 f 3,296,743 C(DMBINATION METAL DQOR AND DOOR FRAME UNIT Donald S. Curl, Pickering, Ontario, Canada, assignor to Al Lipson and Bernard Smith, both of Toronto, On-

tario, Canada Filed Mar. 31, 1964, Ser. No. 356,134 5 Claims. (Cl. 49-382) The invention relates broadly to metal door and door frame combination units with particular reference to the door posts and door stiles incorporated therein and to the weather stripping facilities embodied therein for sealing the spaces between the door and its frame.

Metal doors are now usually supplied to builders in combination with matching frames prefabricated to receive the doors so that a door and its associated frame may be installed together in a wall opening having the appropriate dimensions.

In a combination unit as visualized by the invention the door comprises stiles which constitute the edges thereof and which are joined togther in spaced relation by top and bottom transverse members at least. Expediently said stiles are symmetrical to each other in cross-sectional contour and are preferably extruded so that each is of uniform cross-section throughout its entire length. The door is hingedly hung by one of its said stiles which is then often referred to as the hanging stile of the door.

The door frame visualized by the invention comprises door posts which are preferably symmetrical with each other and cross-sectionally uniform in the same manner as the door stiles aforesaid; said door posts being interconnected in spaced parallel, relation by a lintel which may also have a cross-section essentially similar if not absolutely identical to that of the door posts.

Each said door post is of angular construction having one flange which serves as a door jamb and another flange for overlying the wall surface adjacent to the opening in which the door and its frame are installed.

The door posts visualized by the invention are also equipped with hollow beads capable of being trimmed to present bearings for pintles on hinge leaves connectible to the hanging stile of the door in a well-known manner which is not part of this invention. In the past said hollow beads or hinge beads were usually disposed at the precise corner formed by the jamb and wall surface flanges of the door post.

Various techniques were utilized in the past for Weather stripping or sealing the door and door frame units to block drafts therethrough. One technique of particular interest to the invention involved equipping said door stiles and door posts with what might be called, intercepting elements whereby when the door was closed such element on a door post would assume a confronting or intercepting position relative to a corresponding element on the associated door to sandwich weather stripping therebetweeu providing a seal.

For the sake of orientation the front of the door is herein assumed to be that surface thereof which leads when the door is moved into closed position relative to said door frame; the opposite surface being the back of the door. Thus the front edges of the door are the edges of its leading surface while its back edges are those of the trailing sunface.

In the past the said intercepting elements were respectively constituted by an offset on the jamb flange of the door post serving as a door stop and an abutment on the front edge of the door; facilities being also provided for supporting weather stripping in a position to be sandwiched between said offset and its abutment to provide the required seal.

3,296,743 Patented Jan. 10, 1967 For a variety of reasons which need not be enumerated herein the seal thus provided proved inadequate at times. An object of the invention is therefore to provide a combination metal door and door frame unit equipped with a set of intercepting elements in addition to or alternative with those of the prior art above described; one of said intercepting elements being at the back edge of the door.

A further object of the invention is to provide a combination door and door frame unit as aforesaid wherein the other intercepting element is disposed at the juncture of the jamb and surface flanges.

A still further object of the invention is to provide a combination unit as aforesaid wherein the door post stock is formed with jamb and surface flanges meeting at a corner and a hinge bead on said surface flange; there being a ledge intervening between the said corner and hinge bead forming an intercepting element as aforesaid.

An object of the invention related to each of the foregoing objects is, of course, the provision of weather strip supporting facilities on one at least of said intercepting elements.

A still further object of the invention is to provide stock for combination metal door and door frame units as respectively described in each of the preceding objectives of the invention.

An additional object of the invention is to provide stock as aforesaid with facilities for two seals between the door and door posts and it is a further related object of the invention to dispose such facilities so that they will not interfere with the movement of the door between open and closed positions relative to the door frame.

A more specific object of the invention is that the stock aforesaid will serve for use on each side of a combination unit as aforesaid, i.e. for both stiles and both door posts.

Further and other objects of the invention more or less broad than the foregoing will be apparent from or specifically stated in the hereinafter following description of the elements, parts and principles constituting the invention of which a preferred embodiment is herein described and illustrated in the annexed drawing by way of example only. Like parts of the invention are designated by like reference devices throughout the drawing wherein:

FIG. 1 is an elevational view of a door and door frame combination unit as contemplated by the invention installed in a wall opening;

FIG. 2 an isometric view of a length of extruded stock for the door posts of the door frame shown in FIG. 1;

FIG. 3, an isometric view of a length of extruded stock for the stiles of the door shown in FIG. 1;

FIG. 4, a section along the line IV-IV of FIG. 1 particularly showing a door post mounted on the wall aforesaid and a stile of the door associated therewith, the stile being shown in full and in dotted lines respectively denoting its open and closed positions relative to said door post;

FIG. 5, a section along the line V-V of FIG. 1 particularly showing a door post mounted on the wall and a stile of the door hingedly mounted thereon, the door stile being shown in full and dotted lines respectively denoting its open and closed positions relative to said door post, and

FIG. 6, a section along the line VIVI of FIG. 1 taken through a hinge but corresponding in all other respects to FIG. 5.

Illustrated in FIG. 1 is a combination metal door and door frame unit as contemplated by the invention comprising door D hingedly hung for swinging between open and closed positions relative to the doorway provided by door frame F installed in an opening in wall W.

As will be seen, said door D comprises symmetrical stiles 22 connected in spaced relation by header 4 and kick plate 6; the stiles 2-2, at least, being derived from extrusion 2' of FIG. 3 which, being an extrusion, is of uniform cross-section throughout its length and is hollow having a back wall 8 which forms the specific edge of door D.

The door frame F comprises door posts 1810 connected by a lintel 11; said door posts at least of this embodiment being derived from extrusion 10 of FIG. 2 which, being an extrusion, is of uniform crosssection throughout its length rendering said door posts 1010 symmetrical with each other.

It will be observed that the door post extrusion 10 is of angular form providing each said door post 10 with a jamb flange 12, a surface flange 14 and a corner 16 merging said jamb and

surface flanges

12 and 14; said surface flange 14 overlying the surface of wall W adjacent and around the door frame F as shown in FIGS. 1 and 4 to 6.

Said door post stock 10 is also provided with a hollow hinge bead 20 disposed on the surface flange 14; the hinge bead 20 being separated from corner 16 by a narrow intervening ledge 22 which is provided with formations for seating and retaining weather stripping 23 and is one of the intercepting elements previously discussed; serving as a stop for an abutment on the edge 8 of door stile 2 as will be duly apparent.

Said jamb flange 12 is a relatively long and narrow panel of which one edge is constituted by corner 16; it having an offset 24 at its opposite edge which is also formed to provide seating wherein weather stripping 23 is retainable. The offset 24 is also an intercepting element as contemplated by the invention providing a stop for an abutment constituted by the front edge of the door D as will duly appear.

Stops are thus provided at the respective edges of the jamb flange 12 in the form of ledge 22 and offset 24 separated from each other by the width of the jamb flange 12.

Although not specifically illustrated in the drawing, it will be understood that the side walls of door stiles 22 connected by back wall 8 are included in the surfaces 30-30 of door D and that, for the purposes of orientation, the door surface which leads when the door D is being closed relative to door post 10, as shown in FIGS. 4 and 5, is herein termed its front 30 while its opposite surface is referred to as the back 30' of the door.

In the present embodiment of the invention, said door front and back 30-30 continue outwardly beyond the door edge 8 providing abutments for co-operation with the door stops on the door post 10, namely: ledge 22 and offset 24.

It will be recalled that the invention seeks to provide stile and door post stock which will be suitable for use at both left and right sides of the present combination unit as illustrated in FIG. 1. Thus, notwithstanding that one of said stiles 2 is the hanging stile by which the door D is hingedly hung on a door post 10 by hinge leaves 32, the co-action of each said stile 2 with its associated or companion door post 10 is substantially the same as the co-action of the opposite stile 2 and door post 10.

In other words, as door D swings between open and closed positions relative to the doorway provided by door frame F, each said stile 2 will also move between open and closed positions relative to its own door post 10.

Resultantly the following description of the co-action of one stile 2 and door post 10 should be regarded as equally applicable to the other stile and door post combination.

As has already been explained, the stile 2 has a back wall 8 which forms part of the perimeter of door D and the front and back surfaces 3030' which extend outwardly beyond it co-operate therewith to define a shallow channel such as for accommodating hinge leaf 32 as in FIGS. 5 and 6.

FIGS. 4 and 5, each show a door stile 2 in an open and in a closed position relative to a door post 10; the open position being shown in full lines whereas the closed position is shown in dotted lines in each instance revealing uniform spacing or centering of door D between doorposts 10. Scrutiny of each said view will reveal that the front edge 34 of door D constitutes the abutment engaged with offset 24 whereas the back edge 36 is the abutment for the door stop constituted by ledge 22 the whole of which it substantially overlaps and engages in the closed position of door D.

These views further show that the spacing between the front and back edges of the door D is generally commensurate with the spacing between ledge 22 and offset 24. In addition, it is also revealed thaat whereas the offset 24 projects towards door D, ledge 22 necessarily recedes therefrom to avoid interference with the movement of door D between open and closed positions relative to door frame F.

Thus, while it is immaterial that front edge 34 of door D extends outwardly beyond the back wall 8 of stile 2, such extension of said back edge 36 is quite definitely necessary to ensure its engagement with ledge 22. The said 'back edge 36 of the door D therefore takes on substantial proportions, becoming a frank fin overlapping and blocking the gap 38 between stile 2 and door post 10 as most clearly shown in FIG. 4.

Because of its proximity to the hinge formed by hinge bead 20 and hinge leaves 32, it is thought that the compressive force exerted by said back edge or fin 36 of door D on the weather stripping 23 sandwiched between it and ledge 22 may well be greater than the corresponding force sustained by the weather stripping between the companion pair of intercepting elements, namely front door edge 34 and offset 24, thus providing a better seal between the door D and its frame F. Moreover, it is also believed that such seal is further enhanced by the extra width which is capable of being incorporated in said fin 36 and ledge 22; the offset 24 being expediently maintained relatively narrow to resist deformation by front door edge 34.

However, irrespective of the degree of improvement in the aforesaid sealing properties afforded by the present fin 36 and ledge 22 when used as an alternative to the companion intercepting elements there can be very little doubt that the conjoint use of both sets of intercepting elements as herein visualized provides such improvement to a very significant degree inasmuch as the gap 38 aforesaid between stile 2 and door post 10 becomes completely sealed ofl? thereby.

It may be worthy of mention at this point that various liberties have been taken with the drawing for the sake of clarity. For example, the separation between some of the parts has been over emphasized to enable them to appear in substantial relief and others of the parts have been omitted entirely to simplify the drawing. Thus it is for example that the weather stripping 23 is not shown under the compression which would obtain in the normal use of the parts.

In addition, it is also noteworthy that the weather stripping appearing in FIG. 6 has been trimmed to accommodate hinge leaf 32; being otherwise of the thickness shown, for example, in the other views.

Details of the hinge leaf 32, the pintles carried thereby and the manner of its connection to the door and door post have been omitted herefrom inasmuch as this data constitutes a part of the prior art and is well known in the industry.

The foregoing embodiment of the invention has been described for illustrative purposes only and not in any limiting sense, since it will be obvious that many changes and modifications may be made therein without departing from the true scope of the invention as defined in the claims now following.
