Abstract

The invention relates to a frame for being arranged n an opening, e.g. in a wall or other building face, with a view to mounting of e.g. a window or a door in the opening. The frame is constructed from two or more plates, wherein at least portions of the side members of the frame are formed by the plates joined in a face-to-face relationship with a mutual spacing, whereby a slot is formed between the plates that is accessible from the outside. Such slot may be accomplished e.g. by connection of the plate in a face-to-face relationship by means of spacer blocks, by elevations embossed in at least the one of the plates or by means of fittings. The plates may be made of steel and one or more of the plates may be configured as L-profiles. Moreover, the plates may be pre-folded with embossments in those places where frame corners are to be bent at a later stage, following which the plates are joined to the effect that the plate ends most distally in the frame is slightly longer and is forced slightly away from the other late in the area where the corner is to be formed.

Description

Plate door frame with slot
The present invention relates to a frame for being arranged in an opening, eg in a wall or other building face with a view to mounting of eg a window or a door in the opening.
Background
Today, metal frames are often used for windows and doors as they are comparatively easy to maintain and preserve their original appearance better than eg frames of wood.
Metal frames are typically manufactured by mechanically assembling extruded aluminium profiles that are configured as box profiles with profile parts that are configured for securing special-made sealing lists and to serve as abutments for openable parts such as window frames and door blades and optionally, in connection with recesses, screws or rivets, for securing hinges and other functional fittings.
This kind of extruded frames are quite cumbersome to manufacture from a production point of view. Moreover the manufacturing method means that the produced frames become specific for their intended use, since, already during the extrusion, profile parts are to be configured and, later on, recesses, that depend on the specific use of the frame.
In SE 453933 a joist for openings in eg walls is described that consists of a combined metal beam, wherein the beam is constructed of two L-profiles of steel that combine to form a U-profile. That joist is configured especially with a view to heavy building structures and to prevent thermal bridges by an insulating material being arranged between the two L-profiles in the joist. It is a problem of that joist that, in case the joist is to be used for windows or doors, recesses that are specific to its particular use must also be made therein in order for window frames and door blades to engage with the joist.
Object and description of the invention
It is the object of the invention to provide a solution whereby the above- mentioned problems are obviated.
This is accomplished in that the frame is structured from two or more plates: wherein at least portions of the side member of the frame are formed by the plates that are connected in a face-to-face relationship with a mutual space there between, thereby enabling the formation of a slot between the plates that can be accessed from the outside.
Use of plates in connection with the construction of a frame enables introduction of production-enhancing techniques into the frame manufacturing process as such, eg. point welding and punching techniques. Frame corners may be formed completely or partly by simple bending of the plates or joining by welding. Thus, one is not limited by the profile configuration according to specific extrusion tools. It is possible to improvise exclusively by use of standard bending and cutting equipment. For instance, the plates can be made of thin-sheet steel, carbon-fibre-reinforced material or other composite material having a thickness of eg between 0.5 and 3.5 mm.
By the slot between the plates which being accessible from the outside, it can be used for the insertion of eg sealing lists and for the introduction of and guiding of fittings such as hinges etc. The width of the slot is selected such that current types of fittings can be arranged in the slot and subsequently be secured on desired locations. That liberty is not an option in connection with the prior art extruded frames, where it necessary to determine the location of eg fittings on the frame relatively early on in the process or later on in the process it is necessary to perform machining.
With a frame in accordance with the invention a frame is accomplished which is easier to manufacture and wherein both the manufacture and the use may take place with a higher degree of freedom.
It is a further advantage that screws form mounting of the frame on surrounding building elements can be recessed into the structure in that, in the innermost and visible plate of the frame, holes have been punched that are larger than the screw head of the screws used; and in that the plate adjoining the building surface is provided with punched holes that match the diameter of the screw. Screw heads will hereby be countersunk into the frame profile.
According to one embodiment of the invention the plates in the frame are made of steel. Thereby a frame profile is accomplished that possesses great strength despite the use of relatively thin plates. The heat conductivity of steel and in particular of stainless steel is markedly smaller than is the case with aluminium, which is of consequence to frames that are to be constituents in structures that are to separate heat and cold, eg facade windows and doors.
According to yet an embodiment of the invention the space provided between the plates and hence the slot is accomplished by the plates being connected in a face-to-face relationship by means of spacer blocks. By insertion of spacer blocks a slot is accomplished in a relatively simple manner and the width of the slot can be ensured quite accurately by selection of spacer blocks having dimensions that correspond to the desired width. In connection with the final frame a number of spacer blocks are typically used that are arranged strategically in the frame so that the slot width is maintained, and simultaneously it is avoided that they are caused to block any fittings or other to be arranged in the slot. The securing of the plates to each other via the blocks may take plate eg by means of point welding.
According to yet an embodiment of the invention, the space provided between the plates and hence the slot in the frame is accomplished by connection of the plates in a face-to-face relationship by means of elevations that are embossed at least in the one plate. By connecting the plates by means of embossed elevations a slot is accomplished in a relatively simple manner, and the width of the slot can be ensured quite accurately based on the embossed height of the elevations. In connection with the final frame, a number of elevations are typically embossed that are arranged strategically in the frame such that the slot width is maintained while simultaneously it is avoided that they are caused to be in the way of any fittings or other to be arranged in the slot. The mutual securing of the plates via the elevations can take place eg by means of point welding in the peak of the elevations.
According to yet an embodiment of the invention the space provided between the plates and hence the slot of the frame is accomplished by the plates being connected in a face-to-face relationship by means of fittings. By connecting the plates via fittings inserted into the slot, a slot is accomplished in a relatively simple manner and the width of the slot can be ensured quite accurately based on the thickness of the fitting or the fittings. It is further accomplished that the major part of the fitting is concealed in the frame which hereby appears with an uninterrupted visible side member. The mutual attachment of the plates via the fittings may take place eg by welding.
According to yet an embodiment of the invention, at least one of the plates in the frame is an L-profile. Thereby it is accomplished that the part of the L- profile which is perpendicular to the part which is connected to the other plate extends inwards into the opening. Thereby it is possible for that part to serve as abutment for openable parts such as eg a door or a window.
According to yet an embodiment of the invention both the plates in the frames are L-profiles. Hereby it is accomplished that the two L-profiles can be joined eg in those legs that do not form side member, whereby the side member may appear to be entirely smooth and uninterrupted, unmarked by the joining. Moreover, it may be easier from a production point of view to join the profiles in those legs. Finally, joining of two L-profiles may result in a total of two slots - on the one hand the slot in the side member, on the other one transversally thereto between the other legs of the L-profiles. Hereby an advantage is accomplished in that the latter slot may also be used for insertion of functional elements such as a sealing list or the like.
According to a further embodiment of the invention, embossments in the plates are folded in advance in those places where frame comers are to be bent at a later stage. Then the plates are joined such that the plate that ends most distally in the frame is slightly longer and is forced slightly away from the other plate just about where the corner is to be configured. Hereby it is accomplished that the frame according to the invention may be manufactured as a final product, wherein eg fittings are mounted, holes for mounting are provided, with abutments for openable parts such as door blades or window frames and with final surface coating without having been bent to frame formation. This is an advantage with a view to industrialised production, for storage and transport in that the frames can be handled as profile lengths rather than frames. Bending into frame shape can take place eg on the building site immediately prior to the frame being mounted in a wall opening, since, due to the pre-embossed folding lines, the bending procedure does not require particular tools or equipment.

DESCRIPTION OF EMBODIMENTS
Figure 1 shows a door opening 103 in a wall 113, wherein a frame 101 according to the invention is shown in the door opening on the interior surface 102 of the opening. The frame comprises two plates 105, 107, wherein at least parts of the plate surfaces follow the interior surface 102 of the opening and form side members, and wherein the plates 105, 107 are connected in a face-to-face relationship separated by a space, whereby a slot 109 is formed between the mutually connected plates along at least parts of the opening 103, and wherein the slot 109 is partially open and accessible from the outside, thereby enabling it to be used for functional elements.
Figure 2 shows a cross section of a door opening with frame as shown in Figure 1. The frame according to the invention is constituted by two or more plates 105 and 107 that are joined, with a slot between, in the side member 110 of the frame. In this embodiment the one plate 107 is an L-profile, whose one leg forms an abutment 111 for a door, a window or the like.
Figure 3 is a sectional view of the frame according to the invention formed of two thin-plate profiles 1 ,2 that are combined and fixated relative to each other in such a manner that, between faces 3, 4 that face towards each other, a groove or slot 5 is formed into which a hinge fitting 6 is introduced and secured. Herein both thin-plate profiles have a rectangular cross section.
Figure 4 illustrates a sectional view of the frame according to one embodiment of the invention formed of two thin-plate profiles 7, 8, the one thin-plate profile 7 being L-shaped and the other thin-plate profile 8 having a rectangular cross-section. The side member of the frame is constituted by the profile 8 joined with the one leg of the L-profile 7 and the slot there between 5. The inwardly facing flap 9 may serve as abutment face 10 for eg a door or a window mounted in the frame. According to yet an embodiment of the invention, the two thin plates 7 and 8 are joined by eg a hinge fitting being welded there onto and inserted into the slot 5 and whose thickness thereby determines the width of the slot.
Figure 5 is a sectional view of a frame according to one embodiment of the invention, formed by joining of two thin-plate profiles 11 , 12 that both have L- shaped cross sections. The thin-plate profiles are combined and fixed relative to each other in such a manner that both a slot 13 is formed in the side member of the slot and a slot 14 between the other legs of the L-profiles, which slots may have different widths. It will also appear that in order to ensure a desired width of the slot 13 in the side member, elevations 16 are embossed in the one thin-plate profile in desired height. It will appear how the elevations with abutment against the second thin-plate profile 15 simultaneously constitutes a suitable abutment for point welding for joining of the two profiles. In the shown example the elevation is embossed in the plate away from the door or window opening. Hereby it is accomplished that a smooth and uninterrupted appearance is imparted to the visible interior part of the frame. Elevations 16 to ensure slot width between to thin-plate profiles could also be embossed in the internal thin-plate profile and the embossment could, according to yet an embodiment, be dimensioned such as to form counterboring for the mounting screws that are later to secure the frame to the surrounding building elements, in eg a house. According to one configuration of frames according to the invention elevations may be provided by embossment in both the one and the other thin-plate profile, whereby visible elevations in the interior visible thin-plate profile 11 are embossed only in the event counterboring for the mounting screws is needed, while remaining elevations for instance for establishing abutments for point welding and for ensuring a specific slot width are embossed in the thin-plate profile 12 most proximate the building face.
Figure 6 shows a section through a frame according to an embodiment of the invention which was produced by combination and joining of three thin-plate profiles. In the example it is two thin-plate profiles with rectangular cross- sections 17 and 18 and a thin-plate profile with L-shaped cross-section 19 that form the frame profile in that structure. For dimensioning the width of the column 20 and as abutment points for point weldings, elevations are embossed in the thin-plate profiles 17 and 18. Other possible combinations of plates, L-profiles and other types of profiles, such as eg U- or T-profiles, may similarly and in accordance with the invention be joined to form a frame. According to yet an embodiment of the invention the width of the slot 20 may vary along the side member of the frame and from one cross-section to another.
Figure 7 shows a cross-section through a frame according to one embodiment of the invention, wherein the slot 35 is not interrupted by elevations or spacer elements for mutual fixation, the joining of the two thin- plate profiles 31 and 32 that were combined to form frame profile having taken place by joining of the first legs 36 and 37 of the L-profiles by welding.
Figure 8 shows how a frame according to the invention can be manufactured as an elongate profile length, wherein two thin-plate profiles 7 and 8 are joined in a face-to-face relationship by point weldings 27 where the elevations 28 embossed in the one thin-plate profile 8 abuts on the second thin-plate profile 7. Prior to the joining, corner embossments have been provided in the thin-plate profiles where the profile length is subsequently to be bent to frame shape. The embossment for the corner bend 30 in the thin- plate profile 8 was provided with a larger radius than the embossment for the corner fold 29 in the thin-plate profile 7. The most distal thin-plate profile 8 of the frame must be slightly longer than the other thin-plate profile 7. The difference in length is to be received where corners are to be provided, and therefore, prior to bending, the thin-plate profile 8 must be forced slightly away from the thin-plate profile 7 in the area where the corner is to be formed, in order to thereby enable reception of that part of the longer profile length that is not to be received by the embossment 30 relative to the embossment 29. The frame according to the invention can thus be manufactured entirely completely with eg insertion of fittings, with holes for mounting, with abutments for openable parts such as door blades or window frames, and finally with surface coatings without being bent to frame formation. This is advantageous for industrialisation of production, for storage, and for transport in that the frames can be handled as lengths of profile rather than frames. Bending to frame shape may occur eg on the building site immediately prior to the frame being mounted in a wall opening, since - due to the initial embossments - the bending procedure does not presuppose particular tools or machinery. The bent frame corner is shown encircled in the figure.
Figure 9 is an X-ray section of a frame according to one embodiment of the invention, wherein the frame is provided with a hinge. It will appear how the frame part of a hinge 21 is introduced into the slot that is formed in the side member of the frame between the faces of the thin-plate profiles 23 and 24. If the hinge is eg a standard door hinge having countersunk bores for screws
22 for being mounted in a wooden frame, which are unnecessary for the present frame, such superfluous holes in the hinge fitting can be concealed entirely by the thin-plate profile 24. The figure also shows an embodiment of the invention in which screw holes 25 and 26 in the side member of the frame for mounting of the frame are configured such that the screw hole is larger in the profile 24 than in the profile 23. Hereby it is possible, in the mounting procedure, to select a screw with a screw head that protrudes all the way through the largest screw hole 25 and is hence sunk into the frame. Following mounting of the frame, the hole 25 may optionally, for aesthetic reasons, be closed by a plug or the like, thereby entirely concealing the screw.

Claims

C l a i m s
1. A frame for being arranged in an opening in eg a wall with a view to mounting eg a window or a door in that opening, characterised in that the frame is constructed from two or more plates, of which at least portions of the side member of the frame are formed by the plates joined in a face-to-face relationship with a mutual spacing, whereby a slot is formed between the plates that is accessible from the outside.
2. A frame according to claim 1 , wherein the plates are of steel.
3. A frame according to claim 1 , wherein the mutual spacing and hence the slot are accomplished by connection of the plates in a face-to-face relationship by means of spacer elements.
4. A frame according to claim 1 , wherein the mutual spacing and hence the slot are accomplished by connection of the plates in a face-to-face relationship by means of elevations embossed in at least the one plate.
5. A frame according to claim 1 , wherein the mutual spacing and hence the slot are accomplished by connection of the plates in a face-to-face relationship by means of fittings.
6. A frame according to claims 1-5, wherein at least the one of the plates have an L-profile.
7. A frame according to claims 1-5, wherein both of the plates have L- profiles.
8. A frame according to claims 1-7, wherein embossments are pre-folded in the plates for use in connection with a subsequent bending of eg frame corner.
