Abstract
Description
- The present invention relates to a metallic frame for mounting into an opening in a wall to enclose a door or a window.
- During renovation and modernisation of existing buildings, it is often desirable to replace doors and/or windows with new ones. Due to the fact that the standard sizes of doors and windows may have changed, typically to larger dimensions, during the period between the time of construction and the time of renovation/modernisation of the building, the existing openings in the wall often needs to be enlarged before new door and window frames according to the new standards can be mounted therein.
- A similar problem arises for instance when a building or a part of a building is to be modified to accommodate a disabled person using a wheel chair, since, in most countries, doors of standard sizes are typically too narrow for the passage of modem wheel chairs.
- German patent application No.
DE 44 44 327 Al discloses a steel frame, which can be mounted, possibly without removing the existing frame, within a door opening, when an existing door is to be replaced by another one with a different width and/or thickness. The disclosed frame is rather bulky, and a door of larger width than the existing door enclosed by this type of frame is mounted onto the wall rather than within the wall, i.e. the plane of the door is displaced with respect to the plane of the wall, which results in a solution of poor aesthetic value. - It is an object of the present invention to provide a frame for a door or a window, which enables the door or window to be mounted in the same plane as the wall in a discrete and aesthetic way, although the dimensions of the door or window may exceed the dimensions of a door or window previously mounted within the same opening in the wall.
- The present invention relates to a metallic frame for mounting into an opening in a wall to enclose a door or a window having a first part extending between the wall and the door or window enclosed by the frame, wherein said first part consists of a first, solid metal plate, and the frame further comprises a second metal plate connected at a right angle to the first metal plate and extending into the opening of the frame to be adjoined by the door or the window enclosed by the frame, when the door or the window is closed.
- The construction of a frame, wherein the part extending between the wall and a door or a window enclosed by the frame consists of a single, solid metal plate only, enables for the enclosure of a larger door or window without having to enlarge the dimensions of the opening in the wall. Also, a metallic frame according to the present invention presents itself in a more minimalistic and aesthetic way than conventional door or window frames.
- The expression "window" is to be interpreted in a broad way, meaning that it includes glass walls, glass screens and other more or less transparent building components functioning in practice as windows - although they may not be opened.
- In an embodiment of the invention, the metallic frame comprises a header attached to top parts of two opposing jambs.
- In a further embodiment of the invention, the metallic frame further comprises a transverse bottom member attached to bottom parts of the two opposing jambs.
- A frame for a door may consist of a header and two jambs only, a threshold part at the bottom (for instance made from wood or rubber) being optional, whereas for a window frame, a transverse bottom member being a regular part of the frame will normally be required as well.
- In an embodiment of the invention, the metallic frame is made from stainless steel.
- The use of steel enables for the construction of frames with a higher torsional strength than conventional door or window frames, even though a frame according to the present invention will typically be of substantially smaller dimensions than conventional frames.
- Generally, frames according to the present invention can be expected to be of greater strength than conventional frame made from wood or steel, and they fulfil the normal requirements related to fire security and attenuation of sound.
- In an embodiment of the invention, the thickness of the first metal plate is less than 10 mm, preferably less than 5 mm.
- The choice of a thickness within the specified ranges enables for the enclosure of up to approximately 5 cm broader and higher doors or windows than could have been enclosed by conventional door or window frames within the same openings in the wall.
- In an embodiment of the invention, the width of the second metal plate is less than 3 cm, preferably less than 2 cm.
- The choice of a width within the specified measures assures that the second metal plate does not reduce the dimensions of the door opening unnecessarily.
- In an embodiment of the invention, the width of the first metal plate corresponds to the thickness of a door or a window to be enclosed by the metallic frame.
- This enables for the possibility of mounting the frame in a way so that a closed door or window enclosed by the frame is aligned with the wall, and no parts of the frame protrude from the plane formed by the door or window and the wall.
- In an embodiment of the invention, the second metal plate is connected to the first metal plate along an edge of the first second plate.
- This assures a very minimalistic appearance of the frame.
- In a further embodiment of the invention, the first metal plate and the second metal plate are made from a single metal plate by bending it along a longitudinal direction in a substantially right angle, thus forming an L-shaped plate profile.
- This enables for a simple production of the frames using profiled metal plates without any need for welding.
- In an embodiment of the invention, two or more hinges for one or more doors or windows are fixed to one or both of the jambs by means of spot welding.
- Depending on the weight and width of the door or window to be enclosed, two, three or four hinges may be necessary. By using spot welding, visible screw heads are avoided.
- In another embodiment of the invention, two or more hinges are mounted to the wall through openings in one or both of the jambs in such a way that the hinges are not visible when the door or window enclosed by the frame.
- The provision of hinges that are invisible when the door or window is closed assures an extremely minimalistic appearance of the frame system.
- In an embodiment of the invention, one or more keeps are formed by one or more cut-outs in the frame in combination with one or more striking plates.
- This further contributes to the minimalistic appearance of the frame.
- In a further embodiment of the invention, the positions of the one or more striking plates are adjustable.
- An adjustment in the opening and closing direction of the door or window enables for an adjustment of the keep in order to avoid clattering doors or windows due to draught or for other reasons.
- In an embodiment of the invention, the metallic frame further comprises two or more mounting plates for displaced mounting enabling the frame to be mounted into the opening in the wall at points outside the area physically covered by the frame.
- This enables, for instance, for the mounting of a narrow frame into a broader wall of a light construction and having its strength in the centre part of the wall construction and, at the same time, to mount the frame so as to assure that a door or a window enclosed therein will be aligned with one side of the wall when closed.

Figs. 1a, 1b and 1c illustrate schematically a cross-section of a part ofdifferent frames 1 according to preferred embodiments of the invention. Theframe 1 comprises afirst metal plate 4, which is mounted against awall 2, and asecond metal plate 5, which forms a right angle with thefirst metal plate 4 extending towards the opening of theframe 1. Adoor 3 is enclosed by theframe 1. In its closed position as illustrated in the figure, thedoor 3 adjoins thesecond metal plate 5. - In this embodiment as well as in the embodiments illustrated in
figs. 1b and 1c , no part of theframe 1 protrudes from thewall 2. In fact, in these three embodiments the front edge of theframe 1 and the front side of thedoor 3 are both aligned with the wall. This means that when thedoor 3 is closed, only the hinges 18 (not shown in these figures) and the door handle (not shown) protrude from thewall 2, which gives a very minimalistic and aesthetic appearance of theframe 1. It almost seems like thehinges 18 has been mounted directly in thewall 2 and, in fact, in some embodiments of the invention, some of the mounting screws (not shown) for mounting theframe 1 into the opening in thewall 2 may pass through thehinges 18. - Preferably, the three
frame 1 profiles illustrated infigs. 1a, 1b and 1c are made from steel plates of 4 mm thickness only, which further contributes to the minimalistic appearance of theframe 1. - In
fig. 1a , thesecond metal plate 5 is connected to thefirst metal plate 4 along an edge of thefirst metal plate 4 resulting in an L-shapedframe 1 profile. Preferably, theframe 1 part is made from a single metal plate, which has been bent along its longitudinal axis in order to form the right angle between thefirst metal plate 4 and thesecond metal plate 5. The part of thewall 2 facing the opening, which is not covered by thefirst metal plate 4 can be covered (as illustrated infig. 4b ) with various kinds of materials for obtaining a characteristic appearance of the door opening, such as an old-fashioned look, a modernistic look etc. - In
fig. 1b , thesecond metal plate 5 is not connected to thefirst metal plate 4 along an edge of the latter but rather along its centreline, the width of thefirst metal plate 4 corresponding to the thickness of thewall 2, so that part of thewall 2 facing the opening is completely covered by theframe 1. - The
frame 1 profile illustrated infig. 1c further comprises a longitudinal cavity defined by arounded metal plate 6 for obtaining a softer appearance of theframe 1. -
Fig. 2a illustrates how two cut-outs 7 for a keep have been made in thefirst metal plate 4 of a jamb of aframe 1 of the type illustrated infig. 1a . The figure also shows one of several mountingscrew holes 8 through which theframe 1 can be mounted to thewall 2 by means of a number of mounting screws (not shown), and two assembly screw holes 9 for assembly screws 16 (not shown in this figure) used to assemble theframe 1 by attaching the header and the jambs of theframe 1 to each other (see alsofig. 4a ). -
Fig. 2b illustrates astriking plate 10 to be used with cut-outs 7 as the ones illustrated infig. 2a for a keep. Thestriking plate 10 is designed so that, when thestriking plate 10 is mounted on the back side of thefirst metal plate 4 of the jamb (seefig. 2c ), the twoprotrusions 11 each protrude through a cut-out 7 in thefirst metal plate 4 along the foremost edge of the cut-out 7 for protecting the edge and receiving the bolt and the latch bolt of the lock of adoor 3 enclosed byframe 1, respectively. - The combination of a
flat part 12 adjoining the back side of thefirst metal plate 4 when thestriking plate 10 is mounted, and aU-shaped part 13 provides thestriking plate 10 with a certain elasticity allowing theprotrusions 11 to be moved slightly in the direction perpendicular to thefirst metal plate 4. If the space between theframe 1 and thewall 2 is very narrow, it may be necessary to make a recess in the latter for accommodation of theU-shaped part 13 of thestriking plate 10 when theframe 1 is mounted. -
Fig. 2c illustrates thestriking plate 10 fromfig. 2b when mounted on aframe 1 of the type illustrated infig. 1a . Thestriking plate 10 is mounted as described above with theflat part 12 adjoining the back side of thefirst metal plate 4 and the protrusions 11 (not shown in this figure) protruding through the cut-outs 7 (also not shown in this figure). The figure also shows twoapertures 14 in thedoor 3 for a locking mechanism and a door handle. -
Fig. 3a illustrates the front side part 24 of anotherstriking plate 10 for a keep of aframe 1 according the invention as seen from the front side of theframe 1. Thisstriking plate 10 is mounted in a recess within thefirst metal plate 4 of a jamb by means of a couple of screws (not shown) through mountingholes 25 in thestriking plate 10. Tworesilient parts 26 of thestriking plate 10 extends into two cut-outs 7 in theframe 1 for protecting the edge and receiving the bolt and the latch bolt of the lock of adoor 3 enclosed byframe 1, respectively -
Fig. 3b illustrates the back side part 27 of thestriking plate 10 fromfig. 3a when mounted on aframe 1. The mounting holes 25 continue from the front side part 24 through aback plate 28 for mounting of thestriking plate 10. Aprotection box 29 is mounted onto theback plate 28 covering the cut-outs 7 for receiving the bolt and the latch bolt. - A preferred way of assembling the
frame 1 is illustrated infig. 4a , which shows the upper part of a jamb and one end of a header of aframe 1 with adoor 3 enclosed therein. Thefirst metal plate 4 of the header is prolonged, and theprolonged part 15 thereof is bent over at a right angle to adjoin the back side of thefirst metal plate 4 of the jamb. In the illustrated embodiment, theprolonged part 15 of the header is attached to thefirst metal plate 4 of the jamb by means of twoassembly screws 16 extending from the side of thefirst metal plate 4 of the jamb facing thedoor 3. -
Fig. 4a further illustrates the use of a mountingplate 17 for displaced mounting of theframe 1 allowing theframe 1 to be mounted to thewall 2 by means of mounting screws (not shown) at points outside the area physically covered by the frame 1 (see alsofig. 4b ). The mountingplate 17 may be fixed to the back side of thefirst metal plate 4 of a jamb in various ways, for instance by means of screws or spot welding (not shown). - Finally,
fig. 4a illustrates how ahinge 18 is fixed to the back side of thefirst metal plate 4 of the jamb by means of screws (not shown) or, in a more preferred embodiment, by means of spot welding. -
Fig. 4b illustrates schematically, how adoor frame 1 can be mounted in an opening in awall 2, 19-21 by means of mountingplates 17 for displaced mounting (not visible in this figure). The illustratedwall 2 consists of a double layer ofplasterboard 19 on both sides mounted onto ametal profile 21 around alath 20. If theframe 1 was to be mounted to thewall 2 by means of mounting screws directly through thefirst metal plate 4 of the jamb, these mounting screws would enter thewall 2 somewhere within the double layer ofplasterboard 19, the strength of which is far from being sufficient to securely hold theframe 1 in a fixed and stable position. When using the mountingplates 17 for displaced mounting, the mounting screws (not visible) can instead be positioned to enter thelath 20, which has the sufficient strength to keep theframe 1 in a stable and fixated position. In the embodiment shown in the figure, the mountingplates 17 and the mounting screws are hidden behind acover plate 22, which can be made from various different materials as already mentioned above. It is also illustrated how, in this embodiment, the appearance on the frame side of the door opening is very minimalistic in accordance with one of the objects of the present invention, whereas on the other side of the door opening, the appearance is more conventional including the use of anarchitrave 23. -
Fig. 5 illustrates a hiddenhinge 30 according to an embodiment of the invention. The hinge comprises awall flange 31 that is mounted to thewall 2 through anopening 32 in the jamb, and adoor flange 33 that is to be mounted in a recess in the door 3 (not shown). Between thewall flange 31 and thedoor flange 33 are placed a first 34 and a second 35 hinge part, which are arranged to fold together in such a way, that when thedoor 3 is closed, the hiddenhinge 30 is not visible from any side of thedoor 3.
This type of hinges is known from the art and commercially available, for instance from the German manufacturer SIMONSWERK under the product name TECTUS. - It should be noted that the described embodiments are exemplary only and are not in any way meant to limit the scope of protection, which is defined by the claims listed here below.
