Description

[0001] A frame system for framing an opening in a wall

[0002] FIELD OF THE INVENTION

[0003] This disclosure relates to a frame system for at least partially framing an opening in a wall, in particular to such frame system that comprises a wooden jamb in which a threaded surface is provided for clamping the jamb around the wall. This disclosure further relates to a wall that is provided with such frame system and to a method for at least partially framing an opening in a wall using such frame system.

[0004] BACKGROUND

[0005] Framing an opening in a wall with a wooden frame, such as a door frame or window frame, is quite cumbersome. Typically, this involves drilling holes in a side surface of the wall, inserting plugs and then screwing a wooden jamb to the wall. Thereafter, PUR adhesive is typically applied between the wooden jamb and the wall. This method of mounting a frame system is quite cumbersome and does not allow for re-using the frame system.

[0006] NL7110803A discloses a frame system for framing an opening in a wall. Disadvantage of this frame system is that it is prone to being dislocated. Hence, there is a need in the art for a frame system that allows for a firmer connection between jamb and wall.

[0007] SUMMARY

[0008] To that end, a frame system is disclosed for at least partially framing an opening in a wall. The wall comprises a side surface facing the opening and first and second outer surfaces opposite each other. Typically, both the first outer surface and second outer surface adjoin the side surface. The frame system comprises a wooden jamb. The wooden jamb comprises a first part that is configured to at least partially cover the first outer surface and comprises a second part that is configured to at least partially cover the side surface. The frame system further comprises a threaded surface that is provided in the wooden jamb. The frame system also comprises a clamp element that is configured to, upon being secured to the wooden jamb by a threaded element engaging the threaded surface, exert, at a first part of the clamp element, a force on the wooden jamb and, at a second part of the clamp element, a further force on the second outer surface of the wall herewith clamping the wall between the first part of the wooden jamb and the second part of the clamp element.

[0009] Such frame system allows to easily secure a wooden jamb to a wall and, in doing so, at least partially frame the opening. An opening in a wall that is still to be framed is sometimes referred to as a rough opening. In order to be able to install a door or window in such an opening, the opening has to be framed first. Once the frame has been installed, a window or a door can be placed or hung in the frame. In order for the frame to properly support a door or window, it should be firmly secured to the wall. An advantage of the frame system disclosed herein is that it can be easily secured firmly to a wall. Securing the frame system disclosed herein can be simply performed by causing a threaded element, such as a bolt, to engage the threaded surface in the wooden jamb. As a result, the jamb will be clamped between the first part of the wooden jamb and the second part of the clamp element. Securing the frame system for example does not require any drilling or screwing into the wall itself and does not require great amounts of adhesive, such as PUR adhesive. As a side note, PUR adhesive is preferably prevented altogether, because it may prevent the frame system from being reused. After all, it is very difficult, if not impossible, to dismantle a frame system that has been glued to the wall without damaging it. Hence, the frame system disclosed herein allows for dismantling it without significant damage and subsequent reusing of the frame system.

[0010] The threaded surface being provided in the wooden jamb enables a firm connection between the wall and the wooden jamb. This namely allows to position the jamb, in particular its solid parts, relatively close to the wall. This is not only beneficial in that it enables the frame system to occupy only a limited space of the opening, thus keeping the opening large, but also in that it makes the frame system, in particular the wooden jamb, less prone to being dislocated. Due to the wooden jamb sitting closer to the wall, a relatively small lever is created between the point where the jamb is clamped to the wall and the side of the jamb that faces the opening. As a result, if someone for example bumps into the jamb, the relatively small lever only creates a limited force on the clamping system. If the jamb system extends more into the opening, as is for example the case in NL7110803A, then the abovedescribed lever is larger. In such case, someone bumping into the jamb would cause a significant force on the fastening mechanism which may cause the jamb to come loose.

[0011] It should be appreciated that the jamb of the frame system disclosed herein is consistently described to be a wooden jamb. However, this is not strictly required. For example, the jamb may also be made out of plastic lumber. Therefore, it should be appreciated that in any of the frame systems disclosed herein, the jamb being made out of wood is optional.

[0012] The wooden jamb may be any type of jamb, such as a side jamb or a head jamb. The first part and second part of the wooden jamb may be integrally connected to each other. The wooden jamb typically has an elongated shape having a length extending in a longitudinal direction. The wooden jamb, as viewed in the longitudinal direction may comprise an L-shape, wherein the first part of the wooden jamb may form the short arm of the L-shape and the second part of the wooden jamb may form the long arm of the L-shape. When the frame system is installed, the short arm at least partially covers the first outer surface whereas the long arm at least partially covers the side surface of the wall. As used herein, an element covering a surface does not necessarily mean that the element is in contact with that surface. An important function of any frame system is to at least partially cover a wall in order to provide an esthetically pleasing finish for an observer.

[0013] The clamp element is preferably configured to, upon being secured to the wooden jamb by the threaded element engaging the threaded surface, exert, at its first part, a force on the second part of the wooden jamb.

[0014] The threaded surface may be a steel surface. Irrespective of this, the threaded surface may be an inner surface, meaning that it sits at the inside of some element. Alternatively, the threaded surface may be an outer surface, meaning that it sits at the outside of some element.

[0015] Preferably, upon the threaded element engaging the threaded surface, the threaded element moves into a direction that is perpendicular to the wall in order to clamp the wall between the first part of the wooden jamb and the second part of the clamp element. In particular, when the wall is clamped between the first part of the wooden jamb and the second part of the clamp element, the first part of the wooden jamb is pressed against the first outer surface of the wall while the second part of the clamp element is pressed against the second outer surface of the wall.

[0016] In an embodiment, the frame system is a door frame system that is configured to receive and support a door.

[0017] In an embodiment, the frame system is a window frame system that is configured to receive and support a window pane.

[0018] In an embodiment, the wooden jamb comprises a nut comprising the threaded surface. In such case, the threaded element may be a bolt that is mated to the nut. The nut and / or bolt may essentially consist of stainless steel. This embodiment can be easily fabricated as it requires widely available elements.

[0019] In an embodiment, the nut is an insert nut. The insert nut may be configured to grip into the wooden jamb in order to create a stable and secure connection between the nut and the wooden jamb. This embodiment can be easily manufactured.

[0020] The insert nut is for example a screw-in insert nut or a hammer-in insert nut. A screw-in nut comprises external threading that is configured to bite into the wooden jamb in order to secure itself to the wooden jamb.

[0021] In any case, typically, an insert nut is inserted into a pre-drilled hole. Thus, in order to obtain a wooden jamb having provided therein a threaded surface one may simply drill a hole in the wooden jamb and insert, by screwing or hammering for example, the insert nut into the hole. The internal threaded surface of the insert nut may then function as the threaded surface which the threaded element referred to herein can engage.

[0022] In an embodiment, the clamp element comprises a through-hole configured to receive the threaded element that is configured to engage the threaded surface.

[0023] In an embodiment, the threaded surface is the internal threaded surface of a nut, the nut being provided in the wooden jamb, and the threaded element is a bolt. In such embodiment, the thread of the bolt fits through the through-hole and the bolt head does not fit through the through-hole. Hence, upon the bolt engaging the nut in the wooden jamb, the bolt head will eventually push against the clamp element herewith pushing the first part of the clamp element against the wooden jamb and the second part of the clamp element against the wall.

[0024] In an embodiment, the second part of the wooden jamb comprises an inner surface that faces the side surface of the wall when the second part at least partially covers the side surface, wherein the threaded surface is provided in a recess of the inner surface.

[0025] In an embodiment, the second part of the wooden jamb comprises a main inner surface, which may be understood as the largest inner surface of the wooden jamb that faces the side surface of the wall when the second part at least partially covers the side surface. The main inner surface defines and coincides with a mathematical plane that separates two regions, a first region and a second region. The first region comprises the first part of the wooden jamb and the second region comprises the second part of the wooden element. In this embodiment, the threaded surface is provided in the second region. Optionally, in this embodiment, when the clamp element is secured to the wooden jamb by the threaded element being engaged with the threaded surface, the threaded element is positioned in the second region. Preferably, when the clamp element is secured to the wooden jamb by the threaded element being engaged with the threaded surface, the entire threaded element is positioned in the second region.

[0026] In an embodiment, the clamp element comprises one or more guidance protrusions and the wooden jamb comprises one or more corresponding guidance recesses. Additionally or alternatively, the clamp element comprises one or more guidance recesses and the wooden jab comprises one or more corresponding guidance protrusions. In this embodiment, the one or more guidance protrusions and the one or more corresponding guiding recesses are configured to guide the clamp element to a predetermined position and / or orientation when the one or more guidance protrusions move into their corresponding guiding recesses when the threaded element engages the threaded surface.

[0027] This embodiment further eases the mounting of the frame system, because the guidance protrusions and guidance recesses ensure that the clamp element will always end up in the right position and / or orientation.

[0028] The guidance protrusions may be flaps that are bent out of a principal plane of the clamp element.

[0029] In an embodiment, the clamp element comprises at its second part one or more protrusions that are configured to grip into the second outer surface of the wall. This embodiment enables to secure the frame system to the wall even firmer.

[0030] In an embodiment, the first part of the wooden jamb is provided with a grip element. The grip element comprises one or more further protrusions that are configured to grip into the first outer surface of the wall. This embodiment enables to secure the frame system to the wall even firmer.

[0031] In this embodiment, preferably, at least part of the grip element sits between the first part of the wooden jamb and the wall when the wall is clamped between the first part of the wooden jamb and the second part of the clamp element.

[0032] In an embodiment, at least part of the grip element is positioned in a recess in the first part of the wooden jamb. This embodiment enables that at least part of the first part of the wooden jamb abuts nicely against the first outer surface of the wall.

[0033] In an embodiment, the second part of the wooden jamb comprises an inner surface, which may be the inner surface referred to above, that faces the side surface of the wall when the second part of the wooden jamb is at least partially covering the side surface of the wall. In this embodiment, the threaded surface is oriented such that the threaded element moves into a first direction when it engages the threaded surface. Further, in this embodiment, the wooden jamb comprises, at the threaded surface, an elevated part on one side of the threaded surface and a recessed part on another side of threaded surface. The recessed part is closer to the inner surface than the elevated part. Also, the recessed part extends less in a second direction, that is opposite the first direction, than the elevated part.

[0034] This embodiment allows to ensure that the clamp element, when the threaded element is engaging the threaded surface, applies respective forces to the elevated part and the second outer surface of the wall without applying force to the recessed part. If the clamp element would apply a force to the recessed part, then this may decrease the overall clamping force. The first and second direction are preferably perpendicular to the first and / or second outer surface.

[0035] In an embodiment, the wooden jamb comprises a further threaded surface provided in the wooden jamb. In this embodiment, the frame system further comprises a further clamp element configured to, upon being secured to the wooden jamb by a further threaded element engaging the further threaded surface, exert, at a first part of the further clamp element, a force on the wooden jamb and, at a second part of the further clamp element, a further force on the second outer surface of the wall herewith clamping the wall between the first part of the wooden jamb and the second part of the further clamp element.

[0036] The wooden jamb may comprise even more clamp sets, each clamp set comprising a threaded surface provided in the wooden jamb and a clamp element as disclosed herein, at different positions along the wooden jamb, for example at least three clamp sets, or at least four clamp sets. This embodiment allows to firmly secure the frame system to the wall.

[0037] In an embodiment, the frame system comprises a, preferably wooden, cover jamb that is configured to at least partially cover the second outer surface of the wall. The cover jamb comprises a protrusion and the wooden jamb comprises a corresponding recess that is configured to receive the cover jamb’s protrusion. Additionally or alternatively, the wooden jamb comprises a protrusion and the cover jamb comprises a corresponding recess that is configured to receive the wooden jamb’s protrusion.

[0038] The cover jamb can for example be glued to the wall and / or to the wooden jamb. Further, the cover jamb may comprise a recess that is configured to accommodate at least part of the clamp element and / or of the threaded element.

[0039] One distinct aspect of this disclosure relates to a wooden jamb, which may be any of the wooden jambs disclosed herein. For example, one aspect of this disclosure relates to a wooden jamb comprising a first part that is configured to at least partially cover a first outer surface of a wall and comprising a second part that is configured to at least partially cover a side surface of the wall, wherein a threaded surface is provided in the wooden jamb, e.g. in the second part of the wooden jamb.

[0040] One distinct aspect of this disclosure relates to a wall provided with a frame system according to any of the preceding claims, the frame system at least partially framing an opening the wall. In this aspect, the wall is indeed clamped between the first part of the wooden jamb and the second part of the clamp element. Further, in this aspect, the first part of the wooden jamb at least partially covers the first outer surface of the wall and the second part of the wooden jamb at least partially covers the side surface of the wall.

[0041] One distinct aspect of this disclosure relates to a method for at least partially framing an opening in a wall using any of the frame systems and / or wooden jambs disclosed herein. The method comprises positioning the wooden jamb such that its first part at least partially covers the first outer surface and its second part at least partially covers the side surface of the wall. The method further comprises securing a clamp element to the wooden jamb by causing a threaded element to engage the threaded surface that is provided in the wooden jamb herewith causing the clamp element to exert, at the first part of the clamp element, a force on the wooden jamb and, at the second part of the clamp element, a further force on the second outer surface of the wall herewith clamping the wall between the first part of the wooden jamb and the second part of the clamp element.

[0042] Elements and aspects discussed for or in relation with a particular embodiment may be suitably combined with elements and aspects of other embodiments, unless explicitly stated otherwise. Embodiments of the present invention will be further illustrated with reference to the attached drawings, which schematically will show embodiments according to the invention. It will be understood that the present invention is not in any way restricted to these specific embodiments.

[0057] DETAILED DESCRIPTION OF THE DRAWINGS

[0058] In the figures, identical reference numbers indicate identical or similar elements.

[0059] Figure 1 shows a wall 6 having an opening 4, which is often referred to as a rough opening. The wall 6 is provided with a frame system 2, according to an embodiment, that frames the opening 4. The depicted frame system comprises two wooden side jambs 8a and 8b and a head jamb 8c. These jambs are clamped to the wall and cover an outer surface and a side surface of the wall 4 so that they can support a door. The frame system comprises a plurality of clamp elements 10a - 10h that clamp the jambs to the wall. Their functioning will be explained in more detail below.

[0060] Figures 2A, 2B and 2C show cross-sectional views illustrating further details of the frame system. In particular, figure 2C shows the cross section A-A that is indicated in figure 1 and shows the frame system in a mounted state in which it is clamped around the wall 6.

[0061] Figure 2A shows a wooden jamb 8 according to an embodiment. The wooden jamb 8 comprises a first part 11 that is configured to at least partially cover the wall’s outer surface 44 (indicated in figure 2B) and a second part 12 that is configured to at least partially cover the wall’s side surface 48 (indicated in figure 2B). In this embodiment, the first part 11 comprises an inner surface 28 that faces the outer surface 44 of the wall when the first part 11 at least partially covers outer surface 44 and the second part 12 comprises inner surface 26 that faces the side surface 48 of the wall when the second part 12 of the wooden jamb 8 is at least partially covering the side surface 48 of the wall.

[0062] The wooden jamb comprises a recess 13 that is configured to receive a protrusion 15 of a cover jamb 14 (indicated in figure 2B). The cover jamb 14 once positioned correctly (see figure 2C) at least partially covers a second outer surface 46 of the wall 6. This can be clearly seen in figure 4.

[0063] A feature of the frame system disclosed herein, is that a threaded surface 20 is provided in the wooden jamb 8. In the embodiment of figure 2, this threaded surface 20 is a threaded surface 20 of an insert nut 18 that has been inserted, in particular screwed, into a pre-drilled hole 16 that is present in the wooden jamb 8, in particular that is present in the second part 12. As can be seen in box 21 , the insert nut 18 comprises the threaded surface 20 in its interior. Further, the insert nut comprises an external thread 22 that bites into the wooden jamb when inserted into the pre-drilled hole 16. Figures 2B and 2C show the insert nut inserted into the pre-drilled hole 16.

[0064] Further indicated in figure 2A is a guidance recess 24. In fact, in this embodiment, there are two guidance recesses 24a and 24b that are positioned below each other and that are clearly visible in figure 6. The guidance recesses 24a and 24b are configured to receive guidance protrusions 42 of clamp element 38, which is shown in figures 2B and 2C. The guidance protrusions 42 and the guidance recesses 24 are configured to guide the clamp element 38 to a predetermined position and / or orientation (as shown in figure 2C) when the one or more guidance protrusions 42 move into their corresponding guiding recesses 24. This happens when the clamp element 38 is secured to the wooden jamb 8 by a threaded element 40, such as a bolt, engaging the threaded surface 20. Instead of multiple recesses, one long recess may be provided that may receive multiple guidance protrusions of the clamp element.

[0065] When the clamp element 38 is secured to the wooden jamb 38 (this state is depicted in figure 2C), then the clamp element 38 exerts, at a first part 52 of the clamp element 38, a force on the wooden jamb and, at a second part 54 of the clamp element 38, a further force on the second outer surface 46 of the wall 6. Herewith, the wall 6 is clamped between the first part 11 of the wooden jamb and the second part 54 of the clamp element.

[0066] Advantageously, the wooden jamb 8 as depicted in figure 2 comprises an elevated part 34 on one side of the threaded surface 20 and a recessed part 36 on another side of the threaded surface, wherein the recessed part 36 is closer to the inner surface 26 of the wooden jamb than the elevated part 34. As depicted in figure 2B, the elevated part 34 sits left of the threaded surface 20 and the recessed part 36 sits right of the threaded surface. The threaded element 40 moves into the direction indicated by the arrow in figure 2B when it engages the threaded surface 20. This direction is herein also referred to as the first direction. The direction opposite this first direction is also referred to herein as the second direction. Figure 2B shows that the elevated part 34 extends more in the second direction than the recessed part 36. Such parts that are elevated and recessed relative to each other are beneficial in that they enable that the wall can be properly clamped even if the wall is relatively thin. It is preferably prevented altogether that the clamp element touches the wooden jamb somewhere between the threaded surface 20 and the outer surface 48 of the wall because that may prevent the second part 54, in particular the protrusions 41 , to touch the outer surface 46 of the wall as a result of which the wooden jamb is not clamped around the wall.

[0067] The clamp element 38 comprises a through-hole 39 configured to receive the threaded element 40 that is configured to engage the threaded surface 20. The clamp element 38 further comprises at its second part 54 one or more protrusions 41 that are configured to grip into the second outer surface 46 of the wall. The through-hole 39 and the protrusions 41 can be seen more clearly in figures 5 and 7, which respectively show different embodiments of the clamp element 38.

[0068] Figure 2A also indicates a grip element 32 that is provided at the first part 11 of the wooden jamb 8. The grip element 32 comprises one or more protrusions 33 that are configured to grip into outer surface 44 of the wall 6. Figures 8, 9 and 10 show respective embodiments of the grip element 32 in more detail. The embodiment of figure 2A comprises a through-hole 31 so that the grip element 32 can be screwed to the wooden jamb 8. Preferably, at least part of the grip element 32 is positioned in a recess 30 in the first part 11 of the wooden jamb 8. Preferably, the grip element 32 and the threaded surface 20 are positioned opposite each other and / or at the same longitudinal position along a length of the wooden jamb.

[0069] Figure 2B shows the situation after the wooden jamb 8 has been positioned such that that its first part 11 at least partially covers the first outer surface 44 and its second part 12 at least partially covers the side surface 48 of the wall 6. Then, the threaded element 40, such as a bolt, can be secured to the wooden jamb 8 by causing the threaded element 40 to engage the threaded surface 20. Herewith, the clamp element 38 will exert, at the first part 52 of the clamp element 38, a force on the wooden jamb 8, in particular on the elevated part 34 thereof. At the same time the second part 54 of the clamp element 38, in particular protrusions 41 , will exert a force on the outer surface 46 of the wall. These forces cause the wall 6 to be clamped between the first part 11 of the wooden jamb 8 and the second part 54 of the clamp element.

[0070] Figure 2C shows the frame system as it is mounted to the wall 6. As can be seen, the solid part of the wooden jamb, in particular the second part 12, sits relatively closely to the wall. In other words, the distance between inner surface 26 of the wooden jamb and the side surface 48 of the wall is relatively small. As a result, the wooden jamb is firmly mounted on the wall. Als note that the protrusions 33 and protrusions 41 grip into the wall, which prevents the wooden jamb from sliding over the wall thus providing for an even stronger connection between wooden jamb 8 and wall 6. At least part of the threaded surface preferably sits, as viewed in an outward direction 27 (see figure 2A) that is perpendicular to the inner surface 26, behind a mathematical plane 29 (see figures 2A and 2B) that coincides with the inner surface 26. More preferably, the entire threaded surface sits, as viewed in direction 27, behind plane 29 so that the threaded surface does not occupy any space between the inner surface 26 and the side surface 48 so that the wooden jamb 8, in particular its inner surface 26, can be mounted close to the side surface 48 of the wall herewith enabling a strong connection between frame system and wall.

[0071] Figures 3A and 3B show another embodiment of the frame system. In figure 3A, the wall is not yet clamped. In figure 3B, the wall is clamped between the clamp element and the first part of the wooden jamb. In this embodiment, the elevated part 34 and recessed part 36 are not formed by a skewed surface of the jamb, as is the case in the embodiment of figure 2, but by the jamb comprising a recess 37. This recess 37 may extend fully along the length of the wooden jamb. Alternatively, the recess 37 is only present at the threaded surface. Of course, such a local recess 37 should extend along the length of the jamb (inside of the plane of the figure) as much as is needed to prevent the clamp element 38 from touching the wooden jamb 8 between the threaded surface and the side surface of the wall.

[0072] Figure 4 depicts the frame system and wall in three dimensions. In this figure, a top part of the wall 6 is not shown for clarity. The wall 6 extends further upwards.

[0073] Figure 5 illustrates a clamp element 38 according to an embodiment. In particular, figure 5 shows a top view (top left), front view (bottom left), side view (bottom middle) and a projection (bottom right) of this clamp element. The guidance protrusions 42a and 42b are clearly visible and are simply flaps that have been bent outwards. These guidance protrusions 42a and 42b can be inserted into guidance recesses 24a and 24b as shown in figure 6. Further shown are the protrusions 41 , embodied as teeth, that can grip into the wall. Although an entire row of protrusions is depicted, it should be appreciated that one protrusion would already improve the grip of the clamp element 38 onto the wall 6.

[0074] It may be beneficial if there are more threaded surfaces 20 along a length of the wooden jamb than there are clamp elements. Such redundancy would namely give a user some freedom as to where to mount the clamp element 38, which may be useful if the circumstances would make it difficult to mount the clamp element 38 in some particular position. In that case, another threaded surface 20 may be selected.

[0075] Preferably, a strike plate (not shown) is mounted on the wooden jamb that is configured to receive a latch or bolt of the door in order to keep the door closed. For the frame system disclosed herein, the strike plate preferably comprises plastic. More preferably , the strike plate essentially consists of plastic. Such plastic strike plate can advantageously be sanded to have the right dimensions. If for example a metal strike plate would be used, then this would typically involve hammering the metal strike plate in order to bend a part of the strike plate. Such hammering is undesired as it comes with a risk of dispositioning the wooden jamb.

[0076] Figure 7A illustrates a clamp element 38 according to another embodiment. In particular, figure 7A shows a top view (top left), front view (bottom left), side view (bottom middle) and a projection (bottom right) of this clamp element 38. In this embodiment, the guidance protrusions 42 are embodied as two tubes 42a, 42b, which may be hollow or solid. It is easily understood that, preferably, the corresponding guidance recesses for these tubes have a (round) cylinder shape.

[0077] Figure 7B illustrates a clamp element 38 according to an embodiment that is the same as the clamp element 38 of figure 7A with the only difference that the clamp element 38 of figure 7B comprises at its second part a single protrusion 41 , embodied as a lip 41 , that is configured to grip into the second outer surface of the wall. Such embodiment allows for easy adjustment of the clamp element’s position on the second outer surface of the wall from a first position to a second position. The lip 41 namely does not form indents, or only a relatively shallow indent, in the outer surface of the wall. Indents in the outer surface of the wall hinder repositioning of the clamp element. To illustrate, the teeth as shown in figure 7A may form relatively deep indents in the wall because relatively high pressure is exerted to the wall at the position of each tooth. If the clamp element 38 has to be slightly repositioned, for example because the wooden jamb has to be repositioned, then the teeth will be positioned relatively close the previously created indents. Then, the teeth may easily slide back into these indents herewith bringing the clamp element 38 back to its original position.

[0078] Figure 8A illustrates a grip element 32 according to an embodiment. Figure 8A shows a top view (top left), front view (bottom left), side view (bottom middle) and a projection (bottom right) of this grip element 32. The through-holes 31 a and 31 b allow the grip element 32 to be easily screwed to the wooden jamb. Further, the one or more protrusions 33 are shown as well.

[0079] Figure 8B illustrates a grip element 32 according to an embodiment that is the same as the embodiment of figure 8A with the only difference that the grip element 32 comprises a single protrusion 33, embodied as a lip 33, that is configured to grip into the first outer surface of the wall. Such single protrusion embodiment eases the repositioning of the grip element for the same reasons as given for the lip 41 shown in figure 7B.

[0082] Figure 10 illustrates a grip element 32 according to an embodiment. Figure 10A shows from left to right, respectively, a side view, a back side view and a projection showing the side of the grip element 32. In this embodiment, the grip element is shaped as a plate, wherein one edge of the plate comprises the one or more protrusions 33 configured to grip into the wall. As illustrated by figures 10B, 10C and 10D, the grip element 32 can be placed into a recess 30 in the wooden jamb 8, preferably a recess in the first part of the wooden jamb 8. Figure 10D shows a front view of the grip element 32 sitting in recess 30. If the width of the recess 30 is slightly smaller than the width of the grip element 32, then the grip element 32 can be forced into the recess 30 resulting in the grip element 32 being stuck in recess.

[0083] Figure 10E shows the recess 30 as it may be present in the wooden jamb 8.

[0084] Figure 11 illustrates a grip element 32 according to an embodiment. The grip element 32 is the same as the grip element that is shown in figure 10 with the only difference that the grip element 32 is pre-bent. The curvature of the grip element 32 functions to cause the grip element 32 to be stuck in recess 30 even if the recess is as wide as, or even wider than, the thickness of the grip element.

[0085] Figure 12 shows a frame system according to an embodiment. Herein, the threaded surface is provided in a recess 64 of the inner surface 26. In this embodiment, the threaded surface 20 is provided in a block-shaped element 62 that can be inserted into recess 64. The block-shaped element may be made out of steel. Once the block-shaped element 62 sits in the recess 64, a threaded element, preferably a bolt, can reach the threaded surface 20 via through-hole 63. Through-hole 63 is not necessarily provided with a threaded surface. Thus, by inserting the block-shaped element 62 into recess 64, the threaded surface 20 is provided in the wooden jamb 8.
