The invention relates to an anchor for window mounting and method of mounting the same in a window profile.

An anchor facilitating mounting of windows and doors in buildings is known from the Polish Patent Application P.398648. The anchor is constituted by a body in a form of a sleeve with a bottom. The sleeve opening is threaded along the entire length of the sleeve and the opening in the bottom is threaded along its entire length as well, wherein the diameter of the latter is smaller than the diameter of the opening in the sleeve. The threads in the sleeve opening and in the opening in the bottom are oriented in opposite directions. To facilitate turning of the anchor body, its external surface is provided with external planes shaped for the adjusting wrench. Inside the sleeve thread, a sleeve screw is screwed in, having an opening in which a bottom screw is located, screwed into the threaded opening in the bottom. The sleeve screw or the bottom screw are provided with elements for anchoring in the window or door frame and the sleeve screw or the bottom screw has elements for anchoring in the wall, accordingly.

A mounting anchor made of plastic and a steel nut is known from the Polish Patent Application P.410241. The mounting anchor is comprised of a lower part - an anchor bottom, an anchor stem, an upper part - a sleeve, and a steel nut located under the sleeve flange.

A mounting anchor is known, from the Polish Patent Application P.412508, designed for mounting structural elements, allowing mounting to the anchor by appropriately sliding the mounting element into the base of the anchor mounted to the wall. The anchor has a base, in the form of bent metal sheet, and a metal sheet, a mounting element and a latch with a mobile element, wherein the mounting element is comprised of a flat bar with a rectangular cut-out matching the dimensions of the anchor base, with openings, wherein the metal sheet has a cu-tout, located in the centre, facilitating tilting the mobile element to the predicted position of the mounting element, by which the latch is established, preventing sliding out.

An anchor defined as a standard mounting anchor is known in the art. It is a steel element with a thickness of about 0.6 mm, mounted to the profile by latching it in the inner portion of the profile - by turning it 90° relative to the window frame. Special protrusions fix it perpendicularly do the window frame. A standard mounting anchor has several mounting openings, for dowels of various sizes, the use of which depends on the material in which the windows are mounted. The anchor of this type constitutes a separate element of the window, wherein the anchor mounting is necessary for proper mounting of the window.

If the standard anchor is fastened in a wrong place, this situation will make it impossible to be used again, due to the deformation of mounting elements and the anchor itself caused by the unsuccessful mounting attempt. Attempting to fasten it again in another place will cause clearances on the mounting element and thus unstable mounting of the anchor. Another problem in the state of the art is a very limited movement of the anchor with respect to the vertical position in the window opening, due to low elasticity of the mounting elements. Excessive movement in the vertical plane generally causes unfastening of the anchor. Unfastening of the standard anchor causes many mounting problems and poses great risk during operations, especially if the worker is working on a window pre-mounted in the window opening. In this case, it is necessary to apply significant force to displace the anchor in the plane, and controlling it is difficult. In addition, the need to drill mounting openings in close proximity to the standard anchor causes vibrations, which often affect the position of the anchor and the stability of its mounting (it may become unfastened out of the profile). Drilling in a safe distance from the standard anchor may cause a problem with linear alignment of the mounting opening relative to the anchor and resulting in shifting of the window due to so called anchor warping. Correct spacing between mounted anchors poses a big problem. Incorrect number of anchors or excessive spacing between them is the most common causes of window warping after they are mounted. Another technical problem is a possibility of losing anchors delivered in bulk and inability to pre-mount them due to the transport issues.

Unexpectedly, all technical problems listed above have been solved by the present invention.

The invention relates to an anchor for window mounting, characterised in that it comprises a profile lock bent to the inward of the window profile, which is provided with an edge made on both sides of the profile lock, and a mounting element, which is connected to the profile lock by means of a rotary slot, wherein the rotary slot is provided with a stabilizing element, and the mounting element comprises at least one mounting opening.

Preferably, the anchor is characterised in that the edge of the profile lock is serrated.

Preferably, the anchor is characterised in that the mounting element comprises any number of mounting openings.

Preferably, the anchor is characterised in that the mounting openings are arranged along the entire length of the mounting element.

Preferably, the anchor is characterised in that the mounting openings have various sizes and shapes adapted to the size of the mounting bolts.

Preferably, the anchor is characterised in that the mounting element is a flat bar.

Preferably, the anchor is characterised in that the mounting element comprises at least two opposite longitudinal embossments.

Preferably, the anchor is characterised in that the mounting element comprises at least two shorter opposite longitudinal embossments and at least two longer opposite longitudinal embossments, wherein the gap between the shorter embossments and the longer embossments defines the area of the mounting element subject to bending.

Preferably, the anchor is characterised in that the shorter embossments and the longer embossments are located along the longer edges of the mounting element.

Preferably, the anchor is characterised in that the none of the anchor elements protrudes beyond the plane defined by the ends of the serrated edge.

Another object of the invention is a window frame provided with the anchor for window mounting, wherein the mounted anchor does not protrude out of the contour of the window frame.

Preferably, the window frame is characterised in that it is provided with at least two anchors, wherein the anchors are mounted on the opposite edges of the window frame.

Preferably, the window frame is characterised in that it is provided with at least two anchors, wherein they are mounted on the opposite edges of the window frame in a way that allows coaxiality of the rotary slots in the rotation axis of the parallel edge of the window frame perpendicular to the edge on which the anchors are mounted.

Preferably, the window frame is characterised in that none of the anchor elements protrudes beyond the plane defined by the ends of the serrated edge.

Another object of the invention is a method of window mounting characterised in that it comprises the following steps: a) delivering the window frame provided with at least two anchors, wherein the anchors are mounted on the opposite edges of the window frame, accordingly, b) rotating the mounting elements of the anchor and mounting them to the points located on the inner edges of the window opening in the wall, c) filling the spaces between the outer edges of the window frame and the window opening in the wall with an insulating material.

Preferably, the method is characterised in that the insulating material is a mounting foam and/or a mounting tape.

The disclosed anchor for window mounting, by using a flexible rotary grip, is already mounted to the window at the manufacturing stage of the window. The anchor is mounted to the frame profile using the serrated edges (mounting serrations) located on a centric profile lock. A characteristic feature is an inversion of the position of the mounting serrations in the profile lock, which allows "hiding" the mounted anchor for transport purposes inside the window profile. The anchors are mounted at a distance no greater than 400 mm, starting from the dilatation, and at a distance of 150 mm from the corner. These anchors are mounted inside the profile groove, longitudinally to its axis. With this solution, the problem of transporting the window with the mounted anchor is eliminated, because it does not protrude out of the window contour and is completely hidden.

Before starting the mounting work, the worker bends the anchor away from the plane, rotating it at the required angle with respect to the profile. The flexibility of the rotary mechanism allows setting the position of the anchor at any angle with respect to the profile and changing it smoothly without risking the stability of the anchor. This movement is very smooth, and controlling the position of the anchor does not cause discomfort. The wall-mounted element has several mounting openings, which allow making an opening in the wall conveniently, even in close proximity to the anchor, which allows stable mounting with no risk of shifting or bending of the anchor perpendicularly to the window plane. The anchor is comprised of three main elements, namely a profile lock, bent inward and provided with serrated locking edges on both sides of the profile lock, a rotary slot engaging the profile lock with the mounting element, and a mounting element in a form of a flat bar. The mounting element is provided with mounting openings, arranged along the entire length of the mounting element, and shorter embossments and longer embossments arranged on the opposite sides of the mounting element along its longer edges. The anchor is fastened in by pushing the locking element into the window profile recess (from the outside of the profile). Once the anchor is fastened in, it is fixed in place and its movement is prevented, wherein this effect is a result of the serration of the profile lock. The spacing of the serrated profile lock is variable and adapted to individual sizes of the window profiles, for which the anchor will be adapted. The rotary slot of the profile lock permanently engages the profile lock with the mounting element. The rotary slot allows effortless rotation of the mounting element by any angle, required to dowel it in the wall. This solution facilitates independent rotation of the mounting element with respect to the wall, which has no influence on the stability of mounting the anchor in the window profile. It is possible due to mounting the lock in a fixed position, at 90 degree angle with respect to the edge of the window profile, which simultaneously allows free manipulation of the position of the mounting element relative to the axis of the rotary slot. This solution significantly distinguishes the anchor of the present invention in comparison with the standard anchor, which allows movement relative to the profile axis, in range no greater than 10-15 degrees - because any greater movement may cause unfastening of the anchor's latches from the grooves of the window profile (movement along the axis of the standard anchor causes simultaneous movement along the axis of the anchor's latches).

The main advantage according to the present invention is the fact that this anchor is already fastened at the manufacturing stage of the window and completely hidden inside the recess in outside portion of the profile, which facilitates effortless transport of the window to the end consumer, with no risk of the anchor getting caught on a foreign element and pulling it out as a result - this makes the invention stand out significantly from other solutions available in the market. The distance between the mounted anchors will be defined by the producer taking into account the window manufacturing technology and mounting recommendations for a particular window. With this procedure, the risk of profile warping, due to inappropriate arrangement or number of mounting anchors, is completely reduced. This process significantly improves window mounting on a construction site, because the worker is required only to rotate the mounting element of the anchor by pulling it out of the outer profile of the window - instead of what is the case for the existing solutions for independent mounting of anchors in the profile. The anchor also allows adjusting the distances of the lock for any window profile, which indicates the versatility of the application of the anchor. The proposed solution of the rotary system guarantees stability of the anchor mounting in the window profile, independently from the position of the mounting element itself with respect to the window profile, which is especially important in difficult mounting conditions. Additionally, the anchors are pre-mounted to the windows and hidden inside the profile during transport, wherein the pre-defined and mounted number of mounting anchors allows quick and simple mounting. Another advantage is providing simple and convenient bending of the anchor, as well as adjusting its position with respect to the window profile. An advantage is also providing convenient drilling of the mounting openings in the wall with respect to the axis of the opening in the anchor, by which the problem of deforming and stressing the anchor after pegging is eliminated. It is especially advantageous that the anchor cannot become unfastened during mounting and the mounting time is significantly reduced.

Example 1. The anchor.

The anchor for window mounting comprises a profile lock 1 bent to the inward of the window profile, which is provided with a serrated edge 2 made on both sides of the profile lock 1 , and a mounting element 3 in form of a flat bar, which is connected to the profile lock 1 by means of a rotary slot 4, wherein the rotary slot 4 is provided with a stabilizing element 5. The stabilizing element 5 is an embossment, which reduces the risk of mechanical deformations of the rotary slot 4 and stabilizes the rotary slot 4 against free rotation. The mounting element 3 comprises mounting openings 6 of various shapes, arranged along the entire length of the mounting element 3 and adapted to the size of mounting bolts, and at least two shorter embossments 7 and at least two longer embossments 8 located along the longer edges of the mounting element 3. In all of the anchor, none of the anchor elements protrudes beyond the plane 1a defined by the ends of the serrated edge 2.

Example 2. Mounting the anchor to the window frame.

The method of mounting the anchor comprising pushing the anchor, folded longitudinally in the window profile, into the recesses in the window profile, by means of pushing against the profile lock 1 from the outside of the profile. After fasten! ng the profile lock 1 , the entire anchor is hidden longitudinally inside the window profile, without protruding out of the contour of the window frame, due to the fact that in all of the anchor mounted in the window frame, none of the anchor elements protrudes beyond the plane 1a defined by the ends of the serrated edge 2 (fig. 6).

Example 3. Mounting of a window frame provided with an anchor in the window opening.

The preliminary steps comprise delivering the windows to the construction site and identifying the structures appropriate for the given window recess. After this step, the window sashes are removed from the frame structure by unfastening them from the hinges, wherein the anchors are installed in the window profile in the initial position (fig. 10A), Then, the mounting element 3 of the fastened anchor is grabbed and deflect from the window profile (fig. 10B). Then, the mounting element 3 of the fastened anchor is grabbed and turned initially at an angle of 90 degrees to the plane of the window profile (fig. 10C), by turning the mounting element 3 with respect to the plane of the profile lock 1 , using the rotary slot 4. This procedure is repeated for each anchor placed on the window frame. After turning each of the anchors, the fastening element bendsand (fig. 10D) then the window frame is inserted into the mounting recess, while maintaining dilatations and required mounting clearance that are appropriate according to the mounting instructions. The window frame is fixed in the window recess using plastic or wooden wedges which are placed in the corners of the frame and at a few centimetres distance from each of the window anchors. During wedging, the frame level and its internal and external plumbs are set. Next, the mounting element 3 of the anchor is turned such that at least one of the mounting openings 6 is in the proper position with respect to the required position of screwing the anchor to the side of the window recess in the wall (fig. 10E). This position is determined by the worker and depends on the technology in which the window recess is made. The material from which the window recess is made also defines the type of a mounting peg that is used (dowels, expansion plugs, specialised bolts). At the chosen position of screwing the anchor, a bore is made having a diameter according to the chosen type of mounting, and then a mounting peg is introduced through the mounting element 3 of the anchor, and the mounting element 3 is mounted, transversely to its plane, to the side of the window recess. This operation is repeated for each of the mounting anchors. After finishing this step, each of the anchors is mounted rigidly and permanently, not allowing any movement of the window frame. The sashes removed previously are attached to the frame mounted in the above manner, after which the plumb and level, as well as proper functioning of the window are finally checked. In case of deviations, it is necessary to unscrew the anchors and correct the placement of the window frame. The anchor's design allows turning (rearranging) the anchor's plane again relative to a different angle of deviation from the frame without the need to unfasten it and dowel the mounting element 3 again in a different position of the mounting side of the widow recess. After positioning the frame correctly, attaching the sashes, and verifying the proper functioning of the window, the mounting dilatations are filled with an insulating material. Depending on the required mounting system, the following means are used: single- or two-component low-pressure polyurethane mounting foam I expansion tapes I vapour-barrier tapes I vapour-permeable tapes. The choice of the mounting system is made depending on the house construction technology and its design, as well as final expectations with respect to the installed window joinery. Then, after finishing the mounting, the mounting wedges are removed and the resulting openings are filled with the same insulating material. Leaving a few mounting wedges is allowed as needed and in order to reinforce the stability of heavy structures. After the mounting is finished, the bent and doweled mounting element 3 is hidden under a layer of the internal finishing of the side of the window opening.
