Abstract
A combination of a door and door frame of the type in which the door frame is made from hollow metal sections and the door fits into a rebated part of the frame in the closed position. To eliminate problems created by the gap between the edge of the door (15) and the inner edge (14) of the frame (10, 11) the front face of the door is provided with a laterally projecting flange (19, 20) along its side and top edges which flange overlaps the front edge of the frame when the door is in the closed position. The door has hinges capable of vertical adjustment in relation to the door frame to accommodate any carpet or other floor covering. <IMAGE>
Description
SPECIFICATION
Door and Frame Structure
This invention relates to a door and frame structure which defines the opening for the door and is particularly concerned with the case where the frame structure is made from metal sections (e.g. steel or aluminium). In most cases the door will be of metal, or having a metal frame, but the invention extends to the case where the door is made partly or wholly of wood or other nonmetallic materials.
A problem with a metal section frame structure is that tolerances which occur during manufacture and assembly can give rise to variations in the clearances between the top and side edges of the door and the interior edges of the frame, as the door has to fit into rebated sections of the frame in the closed position. Such variations can occur also due to manufacturing tolerances in the width and height dimensions of the door. These variations can lead to there being gaps between the edges of the door and the surrounding frame which are too large to be acceptable for several reasons. Large gaps are unsightly and can give rise to draughts but, what is perhaps more important, large gaps reduce the effectiveness of a door. as a barrier to fire and smoke and this is of prime concern in public places where there are large numbers of doors (e.g. hotels and hospitals).
Also large gaps make it easier for a thief to attack the door hinges or the locks.
The main object of the invention is to provide an improved door frame structure which will overcome this problem.
According to the invention there is provided the combination of a door and a door frame wherein the frame comprises two upright side members and a transverse top member each formed from a hollow metal section and each section being of cross-section to provide a rebate into which the door fits in the closed position, the door having a laterally projecting flange on each of the side and top edges of its front face, which flanges when the door is in the closed position overlie the gap between said edges and the frame, and the hinge connections between the door and the frame being of an adjustable nature so as to permit the door to be adjusted in position in the vertical direction in relation to the frame.
The invention is illustrated by way of example in the following more detail description which is given with reference to the accompanying drawings wherein: Figures 1 and 2 are diagrammatic sections in the horizontal plane through a door and side members of the door frame showing the door in the closed position in Figure 1 and in the open position in Figure 2.
Figure 3 is a scrap perspective view partly in section showing the upper edge of the door and the transverse top member of the frame.
Figure 4 is a scrap perspective view in exploded form showing the details of the hinging of the door in its frame.
Referring to Figures 1 to 3 the door frame comprises two upright side members each of which is indicated at 10 and a transverse top member 11 each of a hollow section and it will be appreciated that the particular cross-sections shown in the drawings are by way of example only and should be regarded as illustrative only.
An essential feature of the cross-section of each upright member 10 is that it provides a right angle section rebate 12 defined by the interior surfaces 13 and 14 and as will be seen from the drawings when the door 15 is in the closed position it is accommodated within the rebates 12 at each side edge.
Similarly with the upper transverse member on the frame the cross-section provides a rebate 1 6 defined by the surfaces 18 and 17 and again the upper edge of the door fits into this rebate 1 6 in the closed position.
In accordance with the invention the front face of the door has along each vertical side edge a laterally projecting flange 19 and the upper edge of the door has a laterally projecting flange 20, and as will be seen from the drawings when the door is in the closed position the flanges 19 and 20 overlie and obscure the gap between the side and top edges of the door and the interior edges surrounding the rebate in the frame.
To enable the door to open and close properly a hinge of the cranked type is used, as shown diagrammatically in Figures 1 and 2, wherein the hinge pin axis is indicated at 21 and the cranked arm of the hinge indicated at 22 being connected to the edge of the door by the fitting 23. An example of one form of hinge which may conveniently be employed is shown in more detail in Figure 4.
Referring to Figure 4, the hinge pin 21 is carried in the ends of angle brackets 24 secured within the hollow section of the upright member 10 and the cranked hinge arm 22 extends through a T-shaped opening 27 in the inner face 14 of the rebate in the upright section and has a cranked part 25 in the end of which is a squareshaped aperture 26.
The hinge herein described is of a known type particularly convenient for the fitting of the door within the door frame and the detail construction of the hinge itself does not form part of the present invention.
The hinge fitting 23 is secured to the upright
edge of the door frame so as to be obscured from view by the flange 19 and is held in position by the two screws 28 passing through apertures in the fitting 23 and through elongated slots in the
upright edge of the door frame and being engaged
by nuts 30 within the hollow interior of the door.
The purpose of the elongated slots 29 is to enable
the hinge fitting 23 to be adjusted vertically in
position on the edge of the door and to guard
against any movement of the hinge in relation to
the door when in use the inner face of the edge of
the door around each opening 29 is provided with
serrations 31 and each nut 30 is provided with
co-operating serrations 32 on its inner face, so that when the screws 28 are tightened up the serrations 31 and 32 come into mating engagement and thus act to prevent any relative vertical displacement of the fitting 32 in relation to the door.The measure of vertical adjustability provided by the slots 29 has the advantage that it facilitates the fitting of a door in a room where there is an existing carpet, or the fitting of a carpet up against a door wherein after the carpet has been fitted there is the possibility of the lower edge of the door fouling the carpet when the door is opened. Hitherto, with metal doors and doors having metal frames it has been the practice to provide a strip of wood along the lower edge of the door, which strip could be removed and shortened in depth or left off completely in order to accommodate the thickness of a carpet.This feature of the present invention eliminates the necessity for any wooden strip as it enables the position of the door to be adjusted in the vertical direction in relation to its frame to accommodate for a thickness of carpet, whilst at the same time preserving the feature of the flange 20 at the top edge of the door overlying the gap between door and door frame.
The hinge fitting 23 which, as mentioned above, is of a known kind comprises a rigid plate 33 to the inner face of which is secured a channel-section plate 34 of spring metal from the centre of which is cut out a spring tongue 35, and there being a gap in the vertical edge 36. When being fitted in place the door is offered up to the door opening and then manipulated so that the part 25 of each hinge arm enters the slot in the edge 36 of spring plate 34 and eventually the spring tongue 35 snaps into engagement with the aperture 26 to retain the hinge fitting 23 captive upon the end of the hinge arm.
The provision of the flanges 1 9,20 eliminates any unsightly gap around the edge of the door and increases the effectiveness of the door as a fire barrier. The flanges also improve the security aspect of the door in providing a barrier to prevent a potential thief from attacking the lock mechanism or hinges from the outside. The adjustable mounting of the hinges, together with the provision of the upper flange 20 also enables the door to be adjusted in a vertical direction so that its lower edge can clear any carpet or other floor covering.
