The front door post 11 is provided with a door stop 13 which is adapted to receive the front edge of the door when the latter is closed. The rear door post carries a post strip 14 adapted to cooperate with portions of the door hereinafter described.

The door 15 embodying the instant invention is formed of aluminum or similar lightweight material. The door 15 embodies a metallic panel 16 which in the illustrated form of the invention embodies a plurality of interlocked extruded intermediate sections 17, an extruded, interlocked top section 18, and an interlocked bottom section 19. The bottom section 19, as more clearly shown in FIG. 2 of the drawings, comprises an inner portion which as shown is interlocked with the lower edge of the immediately adjacent intermediate section 17 and an outer portion 21.

The outer portion 21 is secured at its upper edge to the inner portion 20 as by means of rivets 22. The outer portion 21 is offset outwardly relative to the inner portion 29 as indicated at 23. The lower edge of the offset portion is interlocked with an outwardly extending flange 24 provided on the inner portion as shown in FIG. 2 of the drawings. The inner portion 20 extends downwardly below the flange 24 to provide a flange 25 which serves to retain the door upon its supporting track 26. Door lifting and supporting mechanism, indicated generally by the reference numeral 27, is mounted within the space provided by the inner portion 20 and outwardly offset portion 21. A more detailed description of the lifting and supporting mechanism and its mode of operation is set forth in applicants Patent No. 2,373,447, granted April 10, 1945, incorporated herein by reference.

The inner and outer portions 213 and 21 are formed of extrusions and constitute the bottom extruded member of the door. Similarly, the front and rear vertical margins of the door panel and the top margin of the door panel are also reinforced by extruded members. The front extruded marginal reinforcing member is designated by the reference numeral 23. It embodies an angular section which includes a flange 29 lying substantially in the inner plane of the door, an outwardly extending flange '30 and a rearwardly extending flange 31. A flange 32 extends outwardly from the outer edge of flange 29 so as to cooperate with the door stop 13 to provide a seal for the front edge of the door. A flange 33 extends rearwardly from the outwardly extending flange 3i) and cooperates with the rearwardly extending flange 31 to provide space for the reception of the front vertical marginal portion of the door panel.

The rear extruded marginal reinforcing member is designated by the reference numeral 34. This member embodies an angular section which includes a rearwardly extending flange 35 lying substantially in the inner plane of the door, an outwardly extending flange 36, and a forwardly extending flange 37. A reinforcing flange 38 extends inwardly from the outer end of the flange 35. The latter flange also carries at its inner end a forwardly and inwardly extending flange 39 which cooperates with the post strip 14 in order to provide a seal for the rear edge of the door. A flange 40 lying substantially in the inner plane of the door extends forwardly from the flange 35. Flange 449 is undercut, as shown at 41, and a groove 42 is provided in flange 35 substantially in alignment with undercut portion 41. The latter and the groove 42 are adapted to receive the side edges of a flexible metallic sealing strip 43 provided with an inwardly and rearwardly extending flange 44 which is also adapted to engage the post strip 14 in order to seal the rear edge of the door. The flanges 37 and 41) provide space for the reception of the rear vertical margin of the panel 16.

The top extruded marginal reinforcing member for the door panel is designated by the reference numeral 45. This member embodies an angular section comprising a vertical flange 46, an upper inwardly extending flange 47 and a lower outwardly extending flange 48. A rabbetted flange 49 extends downwardly from the inner end of flange 48 for securernent to the upstanding flange 50 of the top extruded panel section. A flange 51 extends downwardly from flange 48 in outwardly spaced relationship to the flange 49.

With particular reference to FIGS. 9 and 10 of the drawings, it will be observed that the top, bottom and side extruded marginal reinforcing members terminate short of the corners of the door and that their edges are at right angles to the members. It will be apparent also from FIGS. 2 to 6, inclusive, that the marginal reinforcing members are of uniform cross section throughout their length. As a result of this construction, it is apparent that the extruded marginal reinforcing members can be cut to the desired length and in view of the hereinafter described door construction the need for coping, shaping or mitering the ends of the extruded marginal reinforcing members is obviated.

For the accomplishment of these ends separate corner members are utilized in the door. At the upper front corner of the door a corner member 52 is utilized which embodies an angular section comprising a vertical flange 53, an upper inwardly extending flange 54 and a lower outwardly extending flange 55. The angular section completely fills the corner between the front and top marginal reinforcing members, as shown more clearly in FIG. 3 of the drawings, and is so arranged that the lower flange 55 is seated upon and spans the interval between the flanges 30 and 32 of the front marginal reinforcing member. The dis-position of the corner piece 52 is such that the vertical flange 53 thereof forms a continuation of the flange 29 of the front marginal reinforcing member and a continuation of the flange 46 of the top marginal reinforcing member. Similanly, the upper inwardly extending flange 54 forms a continuation of the inwardly extending flange 47 and the lower outwardly extending flange 55 of the corner member for-ms a continuation of the outwardly extending flange 48. To insure this disposition of the corner member 52. so that it completely fills the upper front corner of the door, the corner memher is provided with an angular portion 56 which depends from the flange 55 and is adapted to nest in the angle provided by the flanges 29 and 36* of the front marginal reinforcing member as shown in FIG. of the drawings.

A corner member 57 is utilized to provide a continuation of the rear marginal reinforcing member and of the top marginal reinforcing member and to completely fill the upper rear corner of the door. Corner member 57 embodies an angular section which comprises a vertical flange 58, an upper inwardly extending flange 59, and a lower outwardly extending flange 6t). Corner member 57 is reinforced by a flange 61 which extends inwardly from the outer portion of flange 58 and forms a continuation of flange 38 of the rear marginal reinforcing member. The inner end of flange 58 carries a forwardly and inwardly inclined sealing flange 62 which forms a continuation of the similar sealing flange 3Q of the rear marginal reinforcing member. When the upper rear corner member 57 is properly disposed in relation to the top and rear marginal reinforcing members, flange 58 forms a continuation of web 46 of the top marginal reinforcing member and a continuation of flange 35 of the rear marginal reinforcing member. Corner member 57 completely fills the upper rear corner of the door. Proper disposition of corner member 57 is insured by an angular member 63 which depends from the lower outwardly extending flange 60 and which nests within the angle formed by the flanges 35 and 36 of the rear marginal reinforcing member.

With reference to FIG. 9 of the drawings it will be observed that the outwardly oflset portion 21'; of the bottom marginal reinforcing member 19 terminates at its ends within the edges of the inner portion it) of the bottom marginal reinforcing member. With this construc tion a corner member 64 is utilized to completely fill the lower front corner of the door. Corner member 64 embodies an angular section which consists of a forwardly extending flange 65 adapted to lie substantially in the inner plane of the door, an outwardly extending flange '66 and a reanwardly extending flange 67. Flanges 68 and 69 extend inwardly in spaced relationship to each other from flange 67 and terminate short of the inner face of flange 65. A substantially inwardly opening channel-shaped portion 70 extends rearwardly from flange 69. The lower edge of the substantially channel-shaped portion terminates in alignment with the lower edges of flanges 68 and 69 while the upper end of portion 70 terminates below the upper end of flange 67.

A flange 71 extends outwardly from flange which continues downwardly below flange 67 to provide a flange 72. A flange 73 extends outwardly from flange 65 and terminates at flange 71.

In assembling corner member 64 with the front and bottom marginal reinforcing members of the door, the corner member is disposed so that flanges 65, 67 and 73 form continuations of flanges 29, 31 and 32, respectively, of the front marginal reinforcing member 248. The substantially channel-shaped portion of corner member 64 is telescoped within the outwardly offset member 21 of the bottom marginal reinforcing member so that it overlaps the inner portion 20 of this member. Flange 67 thereby forms a continuation of the outwardly offset portion 21. The inner portion 20 of the bottom marginal reinforcing member lies inwardly of the flanges 6S and 6% so that flange 65 forms a continuation of the inner portion 20. Flange 72 of the corner member forms a continuation of flange 25 of the inner portion 20. In this manner, the corner member 64 completely fills the bottom front corner of the door. Proper positioning of the corner member 64 relative tothe front marginal reinforcing member 23 is obtained by the nesting of angw lar section 74 formed on the corner member in the angle provided by flanges 29 and 3b of the front marginal reinforcing member.

A corner member 75 is utilized as a continuation of the rear vertical and bottom marginal reinforcing members and to completely fill the corner formed by these members. Corner member 75 embodies an angular section comprising a flange 76 adapted to be disposed substantially in the inner plane of the door, an outwardly extending flange 77, and a flange 78 extending forwardly from the outer end of flange 77. Corner member 75 is also formed with a flange 79 which extends inwardly from the outer end of flange 76 and a forwardly and inwardly extending sealing flange 8E disposed at the inner end of flange 76. A flange 81 extends outwardly from flange 76. A flange 82 extends downwardly from flange 81.

Flanges 83 and 84 spaced relative to each other extend inwardly from flange 78 and terminate outwardly of flange 76. Flange 83 'carnies a substantially inwardly opening channel-shaped portion '85 which at its lower end terminates in the plane of the lower ends of flanges 83 and 84 and at its upper end below flange 78'.

Corner member 75 is assembled with the rear marginal reinforcing member so that flanges 76, 77 and 78 form continuations of flanges 35, 36 and 37, respectively, of the rear marginal reinforcing member 34. I-nwardlyextending flange 79 of the corner member forms a continuation of inwardly extending flange 38 of the marginal reinforcing member. Seaiing flange 89 of the corner member forms a continuation of sealing flange 39 of member 3 This relationship is insured by the angular portion 36 formed on the corner member which nests in the angle provided by flanges 35 and 36 of the marginal reinforcing member.

Corner member 75 is assembled with the bottom marginal reinforcing member 19 so as to completely fill the lower rear corner of the door. In this assembly the substantially channel-shaped portion 85 is telescoped within the outwardly offset portion 21 of the bottom reinforcing member and in overlapping relationship with the inner portion 26 thereof. Flange 78 of the corner member forms a continuation of portion 21 and flange 76 forms a continuation of the inner portion 20 of the bottom reinforcing member Which lies inwardly of flanges '83 and 84. Flange 82 forms a continuation of flange 25 of the inner portion 20. All of the corner members are secured to the marginal reinforcing members by welding.

It will be apparent from the foregoing detailed description that an aluminum door utilizing extruded marginal reinforcing members can be produced economically.

The described door eliminates all coping, shaping or miter-ing of the extruded marginal reinforcing members at the corners of the door. It follows that these reinforcing members can be out to exact size. The instant invention permits the use of any desired panel. The panel may be formed of extruded sections, interlocked as shown, or in any desired manner. Formed panel sections can be utilized as well, if desired.

It will be apparent that numerous changes and modifications in the details of the invention will be clear to those skilled in the art. It is intended, therefore, that all such modifications and changes be comprehended within this invention which is to be limited only by the scope of the claims appended hereto.
