Abstract

PROBLEM TO BE SOLVED: To save space during transportation of a door and a window frame and to easily assemble the door and the window frame. SOLUTION: A kit for forming a metal door and a window frame, is composed of parallel and flat side parts, substantially rectangular U-like metal contours each having a contoured base for forming the periphery of a metal door or a window frame. An opening end of the flat side part is at first bent inward and then folded back below so as to form channels for receiving brackets 6, 7 which are also included in the kit. Ends of two parts of the contour for forming a frame are cut along a flat part at an angle of 45deg. so as to form a miter joint part. A base of one counter is cut so as to receive a base of a contour. L-like brackets 6, 7 are arranged inside of the two contour crossing each other, and outside of a second bracket. The brackets 6, 7 are fixed to a predetermined position by screws piercing through the brackets and the flat part.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to doors and window frames, and more particularly to metal door and window frames.

[0002]

BACKGROUND OF THE INVENTION Metal door and window frames are conventionally manufactured off-site and shipped in perfect form to the construction site where they will be used. Such doors and window frames are manufactured in various standard sizes, but because the construction is handmade, the size of the openings in which such frames are used must be adequate for the standard frames to fit, As the filling material is used around the frame,
Used to have significant tolerances in size.

A further disadvantage of preformed metal frames is that they occupy a lot of space and are therefore uneconomical to transport. It is therefore easy to assemble on site, and therefore can be assembled and transported, and therefore occupies very little space during transport and exactly fits the opening in the building where it is located There is a need for a door frame that can be assembled to a vehicle.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a door or window frame which solves the above problems.

[0005]

In accordance with the present invention, a metal profile having a generally rectangular U-shaped cross section forms the inner periphery of a door or window frame and extends generally perpendicular to a flat portion. A pair of spaced, long, substantially parallel flat portions connected by a contoured base portion having a free longitudinal end folded back inwardly extending perpendicular to the flat portion. A flange portion and a downwardly folded lip portion extending substantially parallel to the flat portion;
Also includes a plurality of L-shaped brackets of one type, wherein the first type of L-shaped bracket fits the inner surface of the contour to the generally flat portion between the base portion and the inwardly folded flange portion. Dimensioned and having on its inner and outer ends a flange of its legs extending substantially perpendicular to the general plane of the bracket, the flange on the outer end of the bracket having a generally flat portion and a downwardly folded lip portion The flange on the inner end of the bracket is dimensioned to be neatly received in the space between, while the flange on the inner end of the bracket abuts the portion of the base of the contour adjacent the generally flat portion, and an L-shaped bracket of the second type Has each leg sized to fit on the outer surface of the profile relative to the generally flat portion, extends substantially perpendicular to the generally plane of the bracket, and the bracket is in contact with the outer surface of the flat portion Sometimes inside each The assembly has a folded back and a flange spaced on the inside and outside surfaces of its legs to fit snugly against the base portion, the assembly having a contoured upright transom and optionally a miter end on a generally flat portion. And can be cut to a length to form a stationary portion of a door or window frame having one contoured base portion end suitably shaped to receive the contoured base portion contours that intersect at right angles;
Two such cut sections can be joined together by inserting appropriate shaped L-shaped brackets on the outer and inner surfaces of the joint, and an L-shaped bracket on each side of the miter joint. A kit is provided for assembling metal door and window frames that are screwed or secured together.

The present invention also provides for cutting the contour portion to a desired length so as to form a miter joint at right angles between the two portions connected as described above, and cutting the base of one contour. A method is provided for manufacturing a door or window frame that is shaped to receive the contour of the base portion of the contour portion that intersects at the ends and that connects the frame members using a pair of L-shaped brackets as described above.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. The frame is formed from a generally U-shaped channel portion, indicated generally by the numeral 1, and comprises a pair of spaced, substantially parallel side portions 2 connected by a base portion 3.
The base part is generally flat and perpendicular to the side part 2, but has a series of steps defining the contour of the door jam or window frame.
The unconnected end of the side part 2 is folded to define a flange part 4 extending perpendicular to the side part 2 and a lip part 5 bent down towards the base of the part 1.

The part for connecting the part 1 at the corner of the frame is 2
It comprises two generally L-shaped brackets 6,7. The legs of the bracket 6, which are intended to be inside the joint, are separated by a distance substantially equal to the distance between the flange 4 and the base part 8 of the base 3; Adjoins the flat portion 2 so as to be able to slide into the space between it and the base portion 8. The bracket 7 is located outside the joint and the flange 4
And a dimension equal to the dimension outside the flat portion 2 between the base portion 3 and the base portion 3. Each of the brackets 6,7 has a folded flange 9,10 on its outer end, respectively, and similar flanges 11,12 on its inner end, respectively.

In the joint, the flanges 9 and 11 are connected to the flange 4
And the base portion 8, the flanges 10, 12 being against the flange 4 and the outer surface of the base portion 8. Brackets 6, 7 are formed with aligned holes for receiving bolts or other fasteners. To join the metal contours to form a frame, the ends may be cut at 45 ° as shown at 13 thereby forming a miter joint. One contour portion 1a is a flat portion 2
Is cut straight across the base 3 with the flat portion 2 cut so as to remain on the ridge of the cut end.

On the other contour part 1b, the end of the base is cut so as to have a stepped edge, so that when the miter ends 13 of the two contours 1a, 1b are joined together, the base part of the contour 1a 3 can be received in a vertical relationship. A slot 15 is located above the cut end of the profile 1b to improve the safety of the joint.
Is formed on the contour 1a to receive the same.

A bracket 6 is introduced between flange 4 and base portion 8 on each side of one of the profiles to form a joint. Then the unengaged legs of the bracket 6 are introduced into the same position on the other contour, the two contours sliding together until the protrusion 15 enters the slot 14 and the miter end 13 comes together. In this position the projection 15 is flattened against the base part 3. The bracket 7 is then introduced outside the joint. Holes are drilled on each side of the joint as required to pass bolts and flats 2 introduced to hold the L-shaped bracket.

The joints formed in this way are very solid, and doors and window frames made in this way are very robust.
