Abstract

An "up-and-over" metal garage door is provided with a decorative timber covering such that it can be borne by the normal door balancing means.

Description

SPECIFICATION Improvements in or relating to doors This invention relates to "up-and-over" metal doors. A great number of these are in use for garages and there appears to be little or no scope for any improvements in the metal doors or their operating and balancing mechanism.

I have however considered whether some improvement could be made in the appearance of these doors which are out of harmony with the architecture of the associated houses. One might consider forming the metal into various surface patterns or painting the doors in various ways but these seem either impracticable or not sufficiently durable. Also attaching decorative parts to the doors seemed an unlikely possibility because the weight of the doors in relation to the balancing mechanism is somewhat critical and making holes in the doors might provide sites for corrosion. Also the doors fit the garage openings rather closely so that interference with opening of the doors could be introduced by attaching bolts or other parts to the doors.

I have however discovered means whereby such doors can be made attractive without incurring these disadvantages.

According to the present invention I provide a covering over substantially the whole of the outer surface of the door with a face covering comprising a framework of wood battens to a sheet of plywood, the plywood being 3 to 5 mm thick and the battens being 7 to 9 mm thick; the overall thickness of the plywood and battens not exceeding 12 mm, the face covering being attached to the door by screws having their heads on the inner surface of the door.

I have found that the weight of such a face covering can be borne by the normal balancing means and the overall thickness of the face covering is acceptable by the normal clearance so as not to interfere with the opening of the door.

The battens can be made in any required patterns to blend with the architecture of the associated house.

The invention will be further described by way of example with reference to the accompanying diagrammatic drawings wherein: Figure 1 is a front view of a door face covering made in accordance with the present invention; Figure 2 is a sectional view on the plane 2-2 on Figure 1; Figure 3 is an enlarged perspective view of the corner of the door at the position shown by the circle on Figure 1; Figure 4 shows the application of the invention to bi-folding type doors; and Figure 5 shows the application of the invention to double doors.

The face covering consists of horizontal top battens 10, bottom horizontal battens 1 1, end vertical battens 12, 13 and intermediate vertical battens 1 6. These are all made of wood approximately 8 mm thick. The battens 12, 13 are about 95 mm wide (as at A on Figure 3). The face covering may conveniently be made in two parts as shown in Figure 1 to facilitate transport. The battens are all attached to a sheet of plywood 18 by waterproof adhesive and by screws 19. The screws 19 have their heads on the inside and are countersunk. The screws 19 may be for example about in the positions shown by the crosses on Figure 1. The plywood is approximately 4 mm thick and will cover the entire face of the steel upand-over door.The two parts of the face covering are applied to the door 20 which usually has an inwardly turned flange 21 and is fixed to it by screws 22 the heads of which are on the inner side of the door. Washers 23 may be placed between the heads of the screws 22 and the door 20. Because the screws 22 are inside the door they are not likely to corrode to any appreciable extent.

By this covering the door may have a very permanent covering or elegant appearance.

Figure 4 shows bi-folding doors comprising two doors 30, 31 with imitation side hinges 32.

Each door appears to be in two parts 35, 36 with imitation hinges 37, 38.

The hinges 37,38 may be made of timber painted and fixed by glue and pins into recesses in mock stiles at the time of making the facing.

The hinges 32 may be made of wood, e.g.

plywood, in two parts 40, 41. Part 40 is painted and fixed with screws to mock stiles and rails at the time of manufacture of the facing. Part 41 is painted and supplied loose for fixing with screwS to the existing door frame when installing the facing.

Claims (filed on 7.1.83) 1. In an "up-and-over" metal door having door balancing means the provision of a face covering comprising: (a) Wood battens 7 to 9 mm thick secured together to form a framework; (b) A sheet of plywood 3-5 mm thick to which said framework is attached, said plywood and framework covering substantially the whole of the outer surface of the door, the overall thickness of the plywood and battens not exceeding 12 mm; whereby the so covered door remains still balanced by said balancing means; (c) The plywood being attached to the battens by screws having their heads between the metal door and the plywood; and (d) Screws attaching the metal door to the plywood and battens, the heads of the screws being on the inside of the door.

2. An "up-and-over" metal door as claimed in Claim 1 , wherein the face covering is made in separable parts divided vertically, each part having top and bottom and vertical battens, the top and bottom battens of one part being arranged to overlap the plywood of the other part when the parts are fixed together.

3. An "up-and-over" metal door as claimed in Claim 1, having imitation hinges representing doors foldable on vertical axes.

4. An "up-and-over" metal door as claimed in
