Definitions

  • the present invention relates to the art of construction and interior decoration, and in particular to the mounting of frames from bended sheet metal, such as frames for bearingdoors or windows in or on a wall.
  • Frames are usually delivered as several separate profiles, which together, after mounting, form a unit.
  • two vertical jambs and a head to be installed horizontally can be mounted in an existing wall opening such that a doorcan subsequently be installed in the frame.
  • Two-piece (metal) frames consisting of a front side and a counterside are known in the art.
  • a door leaf can hereby be attached to the front side of the two-piece frame, by means of hinges installed on one side of the wall opening.
  • the counterside of the two-piece frame is then installed on the other side of the wall opening to cover the wall further.
  • each component in turn may consist of a separate front and counterside.
  • the attachment system described in the present description may, for example, be particularly suitable for mounting said type of two-piece frames, but is not exclusively restricted to this, as is also described in the detailed description below.
  • a wall opening is a rectangular opening with vertical sides and a perpendicular head joint in between.
  • the reveals (the narrow end surfaces in the wall opening) are hereby deemed to be perpendicular to the wall surfaces.
  • the wall opening may be slanted in one or more directions and/or the head joint may not be completely square to the vertical sides.
  • the reveals may be slanted, show convex and/or concave deformation, and/or the distance between the two vertical sides of the opening may deviate from a regular, constant distance (width of the opening) over the entire height.
  • a conventional method for mounting door frames comprises the use of mounting foam to fill the space between frame and wall. Examples of this can be found in, among others, DE202015106530 and WO2016034429. Such approach allows a quick and robust installation, but the used mounting foam may contain unwanted harmful substances for people, animal and/or environment.
  • An additional problem with the use of mounting foam is that the expanding foam may end up on the paint of the frame, which may be difficult to remove and may even cause permanent discolouration or damage of the paint. That is why there is a need in the art for mounting systems that do not require mounting foam, and which preferably also allow a quick, robust and precisely adjustable installation of a door frame
  • the frames are often provided with metal supports, for example welded hereto, whereby the space between the supports and the wall can be filled with (for example, wooden) blocks or shims.
  • a wooden plank, wooden shim blocks or a completely wooden frame can first be attached to the wall, over which subsequently the (for example metal) frame is installed, for example by attaching with nails, screws or glue.
  • this is a time-consuming method, requiring a lot of additional precise bespoke work and/or sawing to size, on the site, of such shim blocks.
  • the frame profile may be warped in the wall opening, such that the (for example three) hinges are no longer perfectly collinearly positioned, resulting in friction upon swinging the door and faster wear and tear
  • a variant of the use of shim blocks relates to methods with wedges to accommodate the differences between wall and frame.
  • this does not provide a good solution for attaching the counterframe in case of thicker walls.
  • the attachment remains visible, which is less desirable, and attaching the frame remains problematic when the reveals of the wall are not perfectly square to the wall surface and/or when the wall is slanted,
  • a system with adjustment screws can be used to bridge the many different distances between the wall and the frame.
  • An example of this can be found in DE19900095.
  • accurately adjusting said screws is also timeconsuming, and the screws may also loosen over time, for example due to vibrations that may be caused by slamming doors ,
  • CH707518 uses self-tapping screws in combination with an.attachment element formed out of a thin steel plate.
  • a disadvantage of this is that the screw is only held in said thin plate by a single revolution of the thread.
  • a pattern of four open holes is used, such that, every screw is not engaged all the way around.
  • This system can be disadvantageous for heavy doors and/or in case of intensive use, as in such situations great forces may act on a small edge of the thin attachment element.
  • a screw that is not inserted squarely to the metal sheet, but thus at an angle, may also twist and/or shift the frame somewhat.
  • the screw head may press the attachment element further toward the wall than is desirable, such that the frame is no longer in the correct position.
  • NL 2 001 812 C2 describes a method for mounting a wooden window frame, in an opening in a wall provided to this end.
  • AT 360 220 B also relates to a wooden frame.
  • US 7 086 204 B2 relates to the mounting of an explosion- resistant window in profile steel.
  • the window is hereby attached to the wall with a normal screw, and shim wood is used to accommodate the tolerances of the wall opening, whereby such shim wood needs to be sawn to size of the specific wall opening.
  • CH 571 145 A5 and US 2016/340890 Al also offer examples of known methods whereby a normal screw is used.
  • it is a disadvantage of these exemplary methods that the use of shim wood is time-consuming and unhandy, as typically it needs to be sawn to size on site.
  • US 2016/340890 Al there is no space to fill (or to bridge) between wall and profile, but this is, in essence, even less easily applicable in practice.
  • TheT difference between a conventional, screw and a spacing screw needs to be emphasised hereby.
  • An important point of difference is the presence of a head in a normal screw. More specifically, the head forms a flange-shaped, radially protruding, part of the normal screw that allows the screw to be screwed tightly against the element in which it is directly (thus to the front on the head-side) screwed. It will be clear that this creates a tension which keeps together and securely connects the respective components the screw penetrates in and/or through like a compact package. This can therefore also be considered an essential characteristic for the efficient, operation of systems as specified in the aforementioned documents according to the state of the art.
  • Embodiments of the present invention use spacing screws, whereby the lack of a head (such flangeshaped radial protrusion) ensures that the screwed together components are not (substantially) compressed.
  • the relative distance of the screwed together components is substantially retained and maintained by applying the spacing screw (hence also the name obviously).
  • a spacing screw does not necessarily possess a screw thread over the entire length.
  • a piece of screw thread can be provided at both ends, but not in the middle.
  • this allows the spacing screw to be secured in both a lower element and an upper element (without tightening them toward each other, as would be the case with a conventional screw), but (for example) slightly or not affecting and/or moving a central element, e.g. a centrally installed block.
  • mounting foam and/or glue may contain unwanted harmful substances and/or may damage the paint of the frame. Mounting foam can also not prevent the deformation of the frame in case of exposure to heat. is an advantage of embodiments of the present invention that they allow a quick and efficient installation of the frame.
  • embodiments of the present invention allow shims, for example wooden sheets and/or blocks, don't need to be sawed to size, on site, resulting- in time savings and increased efficiency, More particularly, shims or time-consuming adjustment systems to accommodate the difference in distance between the wall (for example with surface irregularities) and the frame can be avoided. It is an advantage of embodiments of the present invention that screws without a head are used, such that screwing the screw too tightly does not affect the position of the frame, for example by pushing the frame too far or too tightly against the wall. Because a firm attachment is obtained without increasing tension on the frame, deformation and/or moving of the frame can be avoided, such that, for example, the alignment of the hinges in one line is not disturbed.
  • a proper installation of a door frame can be obtained in a wall opening with irregular wall surfaces and/or in imperfectly formed door openings. For example, no direct contact is required between the mounting bracket and the (possibly slanted) wall.
  • an installed frame can be simply disassembled again and reused and/or recycled, for example.
  • embodiments of the present invention allow a metal component (for example in the form of a C-shaped profile) of an attachment device according to embodiments to be provided with several holes, such that an installer has some, degree of freedom to choose the most suitable attachment point (s) in a specific situation. It is therefore also an advantage that regular components, which can be manufactured in large numbers, are suitable for a wide range of possible frames, door openings, walls and specific application scenarios. It is an advantage of embodiments of the present invention that an attachment system is provided whereby screw connections can be applied at (an) angle(s) to be freely determined, such that in practice an installer can determine an optimal angle for drilling screws into the wall. For example, several screws can be applied in one and the same mounting bracket at different angles, such that a very strong connection can be obtained.
  • the block can be simply replaced by a spare, or a bigger hole can be drilled in the block which subsequently is filled with a (for example hardwood) peg (glued if relevant).
  • a (for example hardwood) peg glued if relevant.
  • embodiments of the present invention allow a cavity between the wall and the frame, after mounting with the system as described herein, to be filled with an acoustic damping material, such as for example rockwool.
  • an acoustic damping material such as for example rockwool.
  • a device and/or method according to embodiments of the present invention realises the abovementioned objective.
  • the present invention relates to an anchoring device for attaching a metal frame, from bended sheet metal, to a bearing structure.
  • the anchoring device camprises a metal bracket and a block, whereby the block is clamped and/or glued in the bracket such that the bracket and the block strengthen each other.
  • the bracket is adapted to allow drilling through the block from a front side of the block to a facing rear side of the block without hereby touching the bracket such that one or several spacing screws can be screwed through the block in the bearing structure without making contact between the block and the bearing structure.
  • the spacing screws therefore do not push the frame, when attaching, toward the bearing structure, such that no unwanted tension and/or possible deformation is created.
  • the block does not have to be adapted to the size of the opening between the bearing structure and the frame either, as it only serves to strengthen the anchoring device. The correct spacing is hereby, on the other hand, substantially guaranteed by the advantageous use of spacing screws.
  • the bracket may comprise a surface which forms the front side of the bracket.
  • a plurality of holes can be provided in said surface to allow drilling through the block via said holes.
  • the plurality of holes may comprise at least a first hole and a second hole which are located on either side of the front side of the bracket such that they also come to be located on either side of a door stop when the anchoring device is used.

  • the block may comprise a solid wooden block, a plywood strip, and/or a block of a composite or synthetic material.
  • the rear side of the block may remain largely uncovered by the bracket, such that the bracket allows drilling through the block from the front side of the block without hitting the bracket on the rear side.
  • the bracket may have a U-shape or C-shape, such that the block is at least partially enveloped and clamped by the bracket.
  • the opening of the C-shape or U-shape may be positioned on the rear side of the block.

  • grooves may be provided in the block, and the ends of the C-shaped bracket can hook into said grooves.
  • An anchoring device may comprise several brackets which clamp at least two (different) edges of the block and hereby leave the front and rear side of the block largely uncovered by the brackets (for example at least 50%, for example at least. 75%, for example at least 80%, for example at least for 90%).
  • the width of the bracket may substantially correspond with the width of the block in at least one direction.
  • An anchoring device may comprise one or several spacing screws for screwing through the block into the bearing structure, and hereby anchoring the block to the bearing structure without the bearing structure and the block hereby (necessarily) touching each other. This results in an anchoring of the frame, when the frame in turn is fastened to the bracket or when the bracket is integrally formed from the frame profile.

In this example it is thus not necessary to explicitly provide holes in a front side of the bracket, cf. surface A, and the installer has a lot of freedom to determine a suitable drilling position through the block. Nevertheless, the bracket 9, or the combination of brackets in this example, increases the strength of the block 12, and vice versa.

  • the block 12 may thus be clamped in, for example, a C-shaped bracket 9, for example over its entire length.
  • the length of the block 12 and the bracket 9 may thus substantially be the same, and the bracket may be aligned relative to the block and, by compressing, form a strong and (substantially) undeformable unit with the block.
  • It is an advantage of a C-shaped bracket that small edges of the bracket on the rear side of the block (facing surface A) can clamp the block, such that the block is firmly held.
  • a wide strip may remain open between said folded over edges, such that when drilling through the block there is no (or little) risk of hitting the bracket material on said rear side of the block.
  • the orientation of the C-shaped bracket may differ from the orientation shown in FIG 2.
  • the opening of the C-shape is, in use, oriented toward the bearing structure 4, but the open sides (on either sides of the block in the direction perpendicular to the plane in which the C- or U-shaped profile are outlined) may be oriented horizontally, to the front and counterside of the frame (see FIG 2), and vertically (see FIG 12; however, note that: the view of FIG 12 corresponds with that of FIG 4, not with that of FIG 2).

  • the block 12 is only enclosed over a section d' of its thickness d by the bracket 9, for example by inserting a leg of the (C- or U-shaped) bracket in a corresponding groove of the block 12.
  • FIG 14 shows an embodiment whereby this principle is combined with several brackets 9, cf. FIG 13, but this can also, subject to the necessary care, be applied to other examples (for example the single bracket in FIG 4), for example, by laterally sliding the block (via the grooves) into the bracket .
  • the bracket may comprise a surface A which covers a corresponding surface of the block (for example is in direct contact herewith over at least a substantial section of said surface) .
  • the bracket comprises at least two further surfaces (or more accurately: at least two further surface segments which distinguish themselves from the segment A by a substantially different orientation) which are at an angle (for example a straight angle) relative to the surface A.
  • These at least three surfaces (surface segments) together form a (for example partial; for example, open) cavity (in at least one dimension) in which the block is enclosed.

  • a plurality of holes 10, 11 may be provided in (and through) the bracket, for example such that the opening of each hole gives access to the underlying material of the block 12.
  • the bracket 9 or brackets is/are at least securely connected to a part of the block 12, for example by gluing, mechanically connecting or squeezing, to increase its strength, while openings in the bracket (and/or an adapted positioning of the bracket relative to the block) allow drilling through the entire block.
  • These openings may, for example, comprise the opening of the C-shape of the bracket 9 on the rear side in combination with the holes 10,11 (for example drilled holes) on the opposite front side (cf. surface A).
  • several brackets may strengthen several edges of the block, such that both a central section of the rear side and of the front side (cf. surface A) of the block 12 remain exposed.

  • embodiments whereby on the rear side a relatively large section of the block is also covered by the bracket, and whereby holes are also provided on this bigger rear side of the bracket, are not. excluded either.
  • the holes on the rear side can be bigger than on the front side, to allow drilling from a hole on the front side at an angle (solid angle; within a cone) with some degree of freedom.
  • the holes are not necessarily round either.
  • the holes on the rear side can have an elongated form (an aspect ratio of, for example, at least 3:2), in cases whereby freedom of (and variation of) the angle at which screws are applied is preferably greater in one direction than in the direction perpendicular thereto.
  • said holes may comprise at least a first hole 10 in a position corresponding with the front side of a two-piece frame and at least a second hole 11 on the counterside of the frame, in other words, on either side of the door stop 14 (stop bead).
  • the hole(s) 10 When applied for mounting a two-piece frame, the hole(s) 10 may thus be covered by the front side of the frame, while the hole(s) 11 on the other side of the door stop 14 remain (s) visible for now until the counterside 7 of the frame is also installed.
  • the device in use is attached to, or already integrally formed in, a profile section intended for the front side 6 of the frame (in spite of possible applications on other frame types) for anchoring to the bearing structure, it may be advantageous to provide (at least) a hole 13 in said front side profile 6 in a position (s) corresponding with the position (s) of the first hole(s) 10.
  • the second hole(s) 11 is/are uncovered at the time of anchoring to the bearing structure, considering that said holes are located in a cantilevered end 25 of the bracket 9 (protruding relative to the front side 6, to be covered afterwards with the counterside 7).
  • both groups 10,11 of holes are separated from each other along the width of the bracket (see width b of the bracket), whereby the space between both groups amounts to, for example, at least one centimetre, for example typically at least a couple of centimetres.

  • said holes 10,11 are not necessarily round (circular), as shown, but may have any form, such as oval-shaped, rectangular, square, etc.
  • the purpose of said holes is to (roughly) indicate a position where the installer, when installing the frame in the uncovered block 12 may drill/screw, and on the other hand to not weaken the structural strength of the bracket too much (for example by retaining sufficient material between and around the holes).
  • the stop bead 14 is not necessarily a fixed part of the frame profile. Referring to FIG 18, said stop bead may also be provided as a separate component, for inserting after anchoring the frame in the position provided to this end to finish the unit.
  • the present invention relates to a frame device, which comprises a profile section of a frame and an anchoring device according to embodiments of the present invention.
  • the frame device thus comprises at least a profile which is part of the frame, with the bracket 9 attached thereto (or the bracket integrally formed herein). More specifically, the bracket may be applied on the inside of the profile, whereby said inside (under normal circumstances) in the wall opening needs to be oriented toward the wall.
  • Embodiments of the present invention may relate to a front side 6 of a two-piece frame (or the frontside profile section thereof), with the bracket 9 attached thereto (or the bracket integrally formed herein).
  • Embodiments of the present invention are not restricted to such two-piece frames, but may be considered as exceptionally suitable for such application.
  • the bracket may be applied or formed on the inside, whereby said inside of the profile piece (of the front side profile 6) is adapted to be oriented to the reveal of the wall when installed (as intended) in a wall opening.
  • the block 12 is applied in (or to, or on) the bracket, such that the surface A of the bracket (at least a substantial part of surface A) is located between the enclosed block 12 and the front side-profile 6.
  • the front side profile 6 may comprise the door stop 14, or a door stop 14 may be included as a loose component (for example in an embodiment construed as a kit of components), whereby the door stop 14 and the front side profile 6 are adapted for a mutual attachment.
  • embodiments may also comprise a counterside 7, whereby the front, and counterside 6,7 are adapted to form the two-piece frame together (however, a further subdivision in separate jambs and/or parts is not excluded).
  • FIG 15 shows an example whereby the bracket is integrally formed in the frame profile, for example in the front side 6 of a two-piece frame.
  • the bracket can hereby be formed by the material forming the frame profile, such that no separate sheet (or other material) is needed to form the bracket.
  • the block 12 may be clamped in the bracket (formed by the frame profile) and/or attached thereto using for example glue, screws and/or another connecting means.
  • the cavity in the profile may also (at least partially; for example using limiting moulds temporarily installed in the profile section) be filled with said material, possibly in combination with a pre-treatment with an adhesive to stimulate the adhesion between the profile material and the poured or formed material of the block.
  • the frame profile may also be provided with a hole or holes 13 which overlap with the at least one hole 10 on the front side (the hole or the group of holes along the width b).
  • This hole or holes 13 in the frame profile may (optionally) be smaller than the underlying holes 10 in the bracket 9. For example, this may allow some degree of freedom in the direction in which a screw is inserted through the overlapping holes 13,10 in the frame profile and the bracket.
  • the device may comprise at least one (preferably several) spacing screw 15 for attaching the frame profile 6 via the bracket 9 to the bearing structure 4. As shown in FIG 5, FIG 6 and FIG 7, said spacing screws 15 can be inserted via one of the holes 13 in the profile 6 and an overlapping hole 10,11 in the bracket 9, to hook into the underlying, bearing structure 4 through the block 12.
  • FIG 8 shows two examples 15a,15b of such spacing screws which are known in the art.
  • the spacing screw may be provided with screw thread over (substantially) its entire length, like in the example 15a, or, referring to example 15b, on the side of the tip a first section of the screw may be provided with thread and on the other side of the screw head a second section of the screw may be provided with thread, whereby both parts are separated from each other by a central section of the screw without thread.
  • both sections are not necessarily provided with the same type (or the same specifications) of thread.
  • the thread on the side of the tip may be adapted for screwing into a wall, or a plug inserted in the wall.
  • the screw thread on the screw head side may, for example, be shorter and/or have a greater diameter.
  • the screw pitch of both sections may be aligned.
  • the screw may be efficiently inserted in the block 12, affixed in the wall 4, and (in the last phase of screwing) firmly hook into the block 12.
  • said outer screw thread will thus dig into the block 12 (which was for example pre-drilled with smaller diameter than the holes 10,11 in the bracket).
  • the head of the spacing screw is referred to above, it will be clear that a spacing screw does not comprise a conventional screw head, within the meaning of a flangeshaped radial protrusion of the body at the head end. Due to the lack of such 'head’’ the spacing screw will thus not exercise any (substantial) pressure on the upper element in which it is screwed in, as would be the case when such flange of a conventional screw would be tightened against it.
  • the spacing screw may comprise a head within the meaning of an engaging device for a screwdriver or screw drill, e.g. a crosshead, a hexagonal bolt form, or another engaging device as generally known in the art for transmitting an angular momentum when tightening the screw.
  • the spacing screw 15 can be provided with a suitable engaging element (such as a groove or other form of engaging cut-away portion) at the screw head end, such as a hexagonal opening or a so-called Torx opening (without any limiting nature).
  • a suitable engaging element such as a groove or other form of engaging cut-away portion
  • the spacing screw 15 does not have a distinct head, such as for example a flat, sunken or round head, but the engaging element can practically continuously run through in the (upper) screw thread (in other words as known for spacing screws). It is an advantage that when tightening the screw no force is created which pushes the attachment device toward the bearing structure (for example the wall), which would be the case when using a screw with a read.
  • the holes in the bracket 10,11 and in the profile 13 may be greater than the diameter of the spacing screw 15 (e.g.
  • the spacing screws do not have to come into contact with the bracket or with the frame during (and thus also after) tightening.
  • the device may also comprise at least one (preferably several) plug which is adapted for inserting in the bearing structure 4, whereby the spacing screw 15 is adapted to fit in the plug (for example according to commonly used correspondences between plug and screw thread sizes).
  • the spacing screw 15 is adapted to fit in the plug (for example according to commonly used correspondences between plug and screw thread sizes).
  • this is optional.
  • plugs may or may not be required (or desirable) .
  • the frame When mounting a frame using the attachment device (s) according to embodiments of the present invention, the frame may, for example, first be installed in the wall opening. It can hereby be correctly positioned and temporary affixed using screw clamps, wedges and/or the door leaf to be installed. It needs to be noted that the use of the door leaf for aligning and temporarily affixing the frame may be particularly advantageous, for example it may contribute to a high efficiency and an accurate installation.
  • the attachment device (s) according to embodiments are hereby installed within, the frame (i.e. for example between the. reveal of the wall and a frame profile), in so far this was not already the case, for example because the attachment device was already attached during manufacture (for example welded) to a profile of the frame, or is even integrally formed as part of said profile.
  • holes may be drilled through the block 12 and in the underlying wall.
  • the holes 13 in the frame profile and the holes 10,11 in the bracket 9 can be used to help position the used drill.
  • the block 12 may also be provided with predrilled holes, for example at positions corresponding with the positions of the holes 10,11 in the bracket 9.
  • pre-drilled holes may have a small diameter and/or are not necessarily made through the entire block 12. More specifically, the diameter may be less, or even significantly less, than the diameter of the thread of the spacing screws 15. This may contribute to a good orientation of the retaining screws upon mounting, for example by guiding the direction of a drill when drilling the eventual holes through the block and in the underlying wall.
  • embodiments are not limited hereto. Indeed, it may also be advantageous to offer the installer more freedom to determine the desired position and orientation of the spacing screws, in other words without being hindered by such pre-drilled holes.
  • the spacing screws 15 can be screwed into the drilled holes, through the block 12 and in the bearing structure 4. These screws secure themselves in the wall (with or without a plug) and in the block 12, such that the frame is anchored in the position in which it is installed (and/or temporarily affixed), without any tension or pressure being exercised on the frame by the screw.
  • the spacing screws 15 may be suitable for installation of wooden components, as is already known in the art. However, in an application of embodiments of the present invention, (for example) a metal profile may be installed, using such (standardised or at least customary) screws intended for mounting wooden components.
  • spacing screws can be screwed in somewhat different directions in the wood (and thus also in the underlying wall), for firmly attaching the frame to the wall, in other words, without any (substantial) remaining range of movement.
  • the number of screws may correspond with the number of holes 10,11 provided in the bracket, or more holes may be provided to offer more freedom to the installer to select suitable positions for applying the screws.
  • the bracket 9 and the block 12 are not brought into contact with the wall, as shown in FIG 11. Consequently, irregular walls are not a problem for correctly mounting the frame. Even if the wall is sufficiently straight and even, it is not necessary to let the block 12 support on the bearing structure 4 (see FIG 10 for example).
  • the dimensions of the block 12 may be adapted in embodiments of the present invention to only cover a limited section of the depth of the frame profile.
