Complete Specification for the Invention entitled: "DOOR CONSTRUCTION" The following statement is a full descript!on of this invention, including the best method of performing it known to me.

.n i i _j i -i 2 j This invention relates to a method of construction of a door, and to a door itself.

Beca,se of transport difficulties, it is quite often desirable to construct a large sliding door on site, and this can be effected relatively easily with a minimum use of fasteners if the site is such that it provides a flat surface on which to assemble a door.

SHowever frequently the site is not sufficiently smooth or flat to enable assembly of such a door to take place, and an object of this invention is to provide a method of construction of a door, and a door when produced by that construction, wherein the construction can be achieved without a need for a very flat surface.

0In this invention, a door comprises frame fitr members, diagonal braces and cladding sheets, and the method of construction includes engaging ends of the Sframe members and joining those frame member ends to form corners of a rectar'gular frame, adjusting the frame members to define a true 7ectangular shape, positioning z 20. diagonal braces in two corners of the frame securing the diagonal braces in position to retain that shape, positioning cladding sheets on the frame, and securing the cladding sheets to the frame.

In some embodiments a further step of insertinig a rail intermediate upper and lower edges is also included.

I-.

-3- If use is made of fasteners which can be inserted quickly and efficiently, the door construction can be achieved in a short period of time. The construction can also be such that the sections used are similar for the peripheral frame members, and are similar for an intermediate rail and diagonal braces, thereby requiring the use of two only cross-sectional shapes.

An embodiment of the invention is described hereunder with reference to and as illustrated in the accompanying drawings, in which: SFIG. 1 is a perspective rear view of a door when constructed in accordance with this invention, '44t FIG. 2 is a fragmentary section taken onr plane t 15. 2-2-2-2 of FIG. 1 and drawn to a slightly larger scale, FIG. 3 is a fragmentry section taken on plane 3-3-3-3 and drawn to a still larger scale, FIG. 4 is a fragmentary "exploded" view showing the manner in which the peripheral frame members join together, the rail joins to those frame members, and the sheets join the frame members for cladding purposes, FIG. 5 is a fragmentary perspective view of a corner, more specifically showing a corner brace arrangement, FIG. 6 is a cross-section through a frame PbI member which is the same as used for a corner brace or intermediate rail, and 4 Fig. 7 is a cross section through a frame member which is the same for vertical and horizontal rails of a peripheral door frame.

In this embodiment a door 10 comprises peripheral frame members which include horizonal members 11 and vertical members 12. These members all have the same cross-sectional shape, specifically illustrated in FIG. 7. The cross-sectional shape win a major T flange 14 parallel to the minor flange 15, and a major web 16 parallel to the minor web 17, the major and minor Swebs being joined by a small intermediate web 18 which is parallel to the flanges. This provides a narrow mouth to the channel wherein the minor web 17 forms a land which will be adjacent the edges of cladding sheets 20, while both the minor and major flanges are useful for securing Sthe rails 11 and 12 together as best seen in FIG. 5, and also securing the cladding sheets to the minor flanges t There is provided an intermediate rail 22 which y is also in the form of a narrow mouthed channel, having one web 23, two flanges 24 projecting from that web, and each flange having an inturned lip designated in PIGS. 5 and 6, each of the inturned lips being parallel to the web 23 to provide surfaces against which the cladding sheets 14 can abut when fastened to the rail. The width of the flanges 24 is such that the Io and 12.

In order to achieve a rigid construction, the peripheral rails are firstly positioned on a supporting surface (for example the ground) and corresponding major and minor flanges 14 and 15 at the ends of the peripheral rails are ibtt1. The bbitting flanges are then joined by fasteners 27 to form corners of a rectangular frame, and diagonal braces 28 are inserted between the minor and major flanges 15 and 14 of the peripheral rails 11 and 12 at the upper corners. After the peripheral rails have been arranged to accurately define 900 atgles between them, fasteners are then used to secure the diagonal braces 28 in position to retain a rectangular rshape. Thereafter the intermediate rail 22 is inserted, and additional fasteners 27 can be inserted in the corners both at the front and at the rear of the door.

The braces 28 have the same cross-sectional shape as the intermediate rail 22, illustrated in FIG. 6.

SAt that stage, the door can be inverted from the position illustrated in PIG. 1, and further fasteners inserted where it is desirable to do so. The cladding sheets 20 are then positioned and these are also secured with fasteners 27. The fasteners 27 are desirably of Sthe self-tapping screw threaded type.

3 6 By merely spreading apart the minor and major flanges of the peripheral rails the braces 28 and intermediate rail 22 can be inserted.

The door when completed provides means whereby water shed from cladding sheets 20 does not enter any channel area as in some prior art doors, but flows over the outside of the door. All joins are of simple sections surfaces of which are at right angles with each other, and can be effected without the need for any corner members previously thought to be essential.
