Definitions
- the present invention relates to a construction panel for assembling with other of such panels, and more particularly to a construction panel for selectively mounting in lap siding and flush siding on a wall.
- the present invention further relates to a system for building selectively lap siding and flush siding on a wall.
- Systems for covering walls and columns are known. Such systems often comprise assembly of construction panels. Such construction panels typically contain a longitudinal flat surface and a top and bottom portion which are arranged to interact with identical or similar panels. In such systems often different construction panels are provided for lap siding of walls and for flush siding of walls. This has a disadvantage in production because often small volumes have to be produced. This is also disadvantageous for the amount of stock because more construction panels will have to be kept in stock. Thus at the end, this is a costly way of offering products to the market.
- US2642968 discloses panel members which may be used to simulate the appearance of lap siding or may be used to simulate sheeting or other wall structure wherein the panels have the appearance of uniform thickness throughout.
- the panel members are made of thin metal sheets and have saw tooth-like flange portions extending along the top and the bottom of each panel. These saw tooth-like flange portions allow the panels to snap into position in two different arrangements to a channel-shaped studding.
- a similar system is disclosed in US4231206 .
- This document discloses a construction panel which comprises both at the top and bottom parts of the panel a channel and an adjacent tongue which extends outwardly from the channel. The shape of the channel is such that it can receive the tongue of an adjacent panel for assembling panels to build up siding.
- the panels can be combined in two different arrangements to form selectively flush siding or lap siding.
- the panels are made of thin sheet metal.
- US4122643 discloses a construction panel which has first and second engaging portions on top and a single engaging portion at the bottom.
- the single engaging portion is adapted to engage either the first or second engaging portion of an adjacent panel so that the panels can be disposed in lap or flush relation as desired.
- US2009/0094914 discloses a construction panel including a first side and a second side.
- a first engagement feature is disposed on or near the first side and a second engagement feature is disposed on or near the second side.
- the second engagement feature is disposed to selectively frictionally engage with the first engagement feature of another similar panel.
- a construction panel incorporating a front portion, a top portion, comprising a first arm and a second arm, and a bottom portion, comprising a third and a fourth arm showing the technical characteristics of the first independent claim.
- the first arm comprises a first assembly position and the second arm comprises a second assembly position.
- the third arm comprises a positioning surface for interacting selectively on a first or second assembly position of a second similar construction panel in respectively lap mounting or flush mounting. This provides the user a choice between two ways of mounting.
- the fourth arm disposes of a protrusion which facilitates installation of the construction panels and avoids intrusion of moisture and wind. By the structure of a fourth arm with an aligned front surface and an extension surface which makes contact with the front surfaces in both mountings, the structure ensures overlap between two subsequent panels in both mounting methods and a good contact on a front surface avoiding intrusion of moisture and wind.
- the distance between the front surface of the construction panel and the front surface of the first arm is equal to the distance between the former front surface and the extension surface on the back side of the protrusion.
- the first or second arm of the construction panel comprises guiding means for guiding another construction panel towards the first or the second assembly position for lap or flush mounting respectively.
- the presence of these guiding means leaves no possibility for misalignment and facilitates mounting of the panels.
- the third arm of the construction panel is equipped with guiding means for guiding the positioning surface on the third arm towards the first or the second assembly position of an underlying construction panel for lap or flush mounting respectively. This again facilitates mounting of the panels.
- the guiding means of the third arm comprise a slot for encompassing a projection of the second arm of an underlying construction panel.
- This projection has a width corresponding to that of the slot.
- the first assembly position on the first arm and the second assembly position on the second arm both have an inclined surface for receiving the positioning surface of the third arm of a second construction panel wherein the inclined surfaces and the positioning surface are substantially parallel, allowing easier installation of the panels.
- the inclined surfaces ensure that during installation a panel moves towards its end position and thus that the protrusion on the fourth arm is in contact with the front surfaces.
- the construction panel further comprises in the longitudinal direction on one side a groove and at the opposite side a tongue.
- This lateral interacting mechanism provides a stable and easy mounting, excludes any lateral movement of the panels and shows no gaps between the panels.
- This method of building lap siding or flush siding has the advantage that the user can mount in the two mounting methods without compromising on the case of installation.
- the construction panel comprises an identical cross section, comprising a front portion, top portion and bottom portion, over a relatively long length in a longitudinal direction.
- the top portion is not aligned with the front portion.
- the construction panel comprises at one end of a tongue and at the opposite end of the panel of a groove. Both tongue and groove interact with a subsequent construction panel.
- the groove comprises a recess arranged to receive at least a portion of the tongue of the top portion of a subsequent construction panel, when this subsequent construction panel is positioned at an offset of the first construction panel. The effect is such that using an offset permits easier installation of the panels: once laterally in the right position, the panel can be lowered and mounted on the underlying panel.
- top, bottom, over, under and the like in the description and the claims are used for descriptive purposes and not necessarily for describing relative positions. The terms so used are interchangeable under appropriate circumstances and the embodiments of the invention described herein can operate in other orientations than described or illustrated herein.
- FIG. 1a Figure 1b and Figure 1c , cross sections of a construction panel 1 and an identical construction panel 2 in accordance with an embodiment of the present invention are shown.
- Construction panel 1 is produced by extrusion. Therefore, the cross section of construction panel 1 is representative for the whole length of the panel.
- construction panel 1 may be produced by a different process known in the art such as for example injection molding.
- the construction panel may not have an identical cross section over the whole length of the construction panel 1 as will be discussed in more detail below in the paragraph where the lateral interacting mechanism is discussed.
- Construction panel 1 comprises a front portion 20 having a front surface 22 and a back surface 24, and a first predetermined thickness 26 between the front surface 22 and the back surface 24.
- the construction panel 1 further comprises a top portion 30 and a bottom portion 60.
- Figure 4 illustrates the top portion 30 in an enlarged view.
- Top portion 30 comprises a first arm 7 and a second arm 8.
- the first arm 7 extends on the back surface 24 making a corner over about 90 degrees towards the outside of the construction panel 1 and forming a first arm front surface 32 and a first arm back surface 33 substantially parallel to front the front surface 22 and the back surface 24.
- the first arm 7 further comprises a first arm end surface 6 angled with respect to the first arm front surface 32 to form an inclined gliding plane.
- First arm 7 serves as a first assembly position 36.
- the angle 38 between the first arm front surface 32 and the first arm end surface 6 is smaller than 90 degrees. This has the advantage that an interacting construction panel 1 during assembling will easily position itself on the first assembly position 36 as will be described in more detail below.
- the angle 38 is preferably between 30 and 60 degrees. In the embodiment of Figure 4 , the angle 38 is about 45 degrees.
- the second arm 8 extends on the first arm back surface 33 making a corner over about 90 degrees towards the outside of the construction panel 1 and forming a first surface 42 and a second surface 43 substantially parallel to the front surface 22 and the back surface 24. This portion can be called the first section 52 of the second arm.
- the second arm 8 then turns back over about 45 degrees forming a third surface 44 and a fourth surface 5. In alternative embodiments this angle may be different from 45 degrees.
- the third surface 44 is angled with respect to the first surface 42 and the fourth surface is angled with respect to the second surface 43. This angled portion can be called the second section 56 of the second arm 8.
- the second arm 8 then turns again to direct a third section 54 of the second arm 8 in the same direction as the first section 52 but closer towards the front surface 22 forming a fifth surface 46 and a sixth surface 47.
- the fifth and sixth surfaces 46, 47 are substantially parallel to the front and back surfaces 22, 24 and forming a second predetermined thickness 55.
- the second predetermined thickness 55 of the third section 54 of the second arm 8 is substantially the same as the first predetermined thickness 26 of the front portion 20. In alternative embodiments, the second predetermined thickness 55 may be more or less than the first predetermined thickness 26.
- the second arm 8 ends with an end surface 48.
- the end surface 48 is in the embodiment of Figure 4 slightly rounded.
- the third section 54 will easily enter a slot during assembly as will be discussed in more detail below.
- fourth surface 5 of the second arm 8 is parallel to the first arm end surface 6 of the first arm 7. This has the advantage that a portion of an interacting construction panel 1 which is designed to interact with the first arm end surface 6 will also interact optimally with the fourth surface 5. This will be illustrated in more detail below when the interaction of two construction panels is discussed.
- the second arm 8 and especially the second section 56 of the second arm 8 serves as a second assembly position 59.
- Figure 5 illustrates the bottom portion 60 in an enlarged view.
- the bottom portion 60 comprises a third arm 9.
- the third arm 9 extends on the back surface 24 making a corner over about 90 degrees towards the outside of the construction panel 1 and forming a third arm front surface 62 and a third arm back surface 63 substantially parallel to the front surface 22 and the back surface 24.
- the third arm 9 further comprises a slot surface 66 substantially perpendicular to the back surface 24 and extending from the back surface 24 towards the third arm front surface 62.
- a third arm top surface 64 is extending on the back surface 24 and angled over an angle 68 with respect to the back surface 24.
- the third arm top surface 64 forms the connection between the back surface 24 and the third arm back surface 63. In the embodiment of Figure 5 the angle is about 45 degrees.
- the angle 68 may be more or less than 45 degrees.
- the third arm 9 further comprises a positioning surface 4 starting at the end of the third arm front surface 62 and forming an angle 69 with respect to the third arm front surface 62.
- the third arm 9 ends with an end surface 67.
- the end surface 67 is in the embodiment of Figure 5 slightly rounded and connects the end of positioning surface 4 with the end of the third arm back surface 63 in a rounded way. This has the advantage that the third arm 9 will be received smoothly in an interaction portion of a corresponding construction panel 1 during assembly.
- the bottom portion 60 further comprises a fourth arm 10.
- the fourth arm 10 comprises a fourth arm front surface 72 which is an extension of the front surface 22 in the same plane and forming in practice thus a single surface.
- the fourth arm further comprises a fourth arm back surface 74 slightly angled with respect to the back surface 24 towards the front surface 72.
- the angle 76 is preferably between 0 and 10 degrees. In the embodiment of Figure 5 , the angle is about 2 degrees. In an alternative embodiment the angle 76 is zero and the fourth arm back surface 74 is parallel to the fourth angle front surface 72.
- the fourth arm back surface 74 together with the third arm front surface 62 and the slot surface 66 form a slot 78.
- the fourth arm 10 further comprises at the end a protrusion 3.
- the protrusion 3 extends on the fourth arm back surface 74 away from the fourth arm front surface 72 and in a direction perpendicular to the fourth arm front surface 72 which is the X-direction illustrated on the drawing.
- the extension ends in an extension surface 70.
- the extension surface 70 is substantially parallel to the front surface 22 and is positioned in substantially the same plane as the back surface 24.
- the fourth arm 10 ends with an end surface 71.
- the end surface 71 is connecting the end of the fourth arm front surface 72 and the outside end of the extension surface 70.
- the end surface 71 is angled with respect to the fourth arm front surface 72 towards the inside of the construction panel 1.
- the angle 75 is smaller than 90 degrees. This has the advantage that, when the construction panel is assembled, water will be guided to the front surface of the construction panel 1.
- the construction panels 1 can be mounted according to two different arrangements. Either the visible front surfaces 22 of all construction panels 1 are mounted substantially in the same plane (this is called “flush mounting”), or the front surfaces 22 of all construction panels 1 are arranged cascade-like (this is termed "lap mounting"). According to the latter arrangement, each construction panel 1 is on the top portion 30 partly covered by a part of the bottom portion 60 of another construction panel 1, and all construction panels 1 are slightly tilted. This will be illustrated in more detail below. Referring now to Figure 1b and Figure 2 , assembling a construction panel 1 on an identical construction panel 2 will be described in more detail for flush mounting and thus for building a flush siding on a wall.
- first construction panel 2 is mounted to the wall. This can for example be done by providing one or more screws through the second section 52 of the top portion 30 of the construction panel 2. In other embodiments however the connection of the construction panel to the wall can be done by any other connecting technologies known in the art. In that way, surface 43 is connected to the wall or to a frame on the wall. Subsequently, a following construction panel 1 is brought in position above the first construction panel 2. The following construction panel 1 is then moved downwards such that the slot 78 of the following construction panel 1 moves over the third section 54 of the first construction panel 2.
- the width of the slot 78 is designed such that it corresponds to the width 55 of the third section 54.
- This interconnection of the top portion 30 and the bottom portion 60 has several advantages. First, when moving downwards, the inclined surface 4 of the following construction panel 2 creates guidance for guiding the slot 78 towards the third section 54. Secondly, the inclined surface 74 of the following construction panel 1 avoids that the third section 54 of the following construction panel 1 gets stuck in the slot 78.
- the extension 3 and especially the extension surface 70 contacting the first arm front surface 32 ensures that the different front surfaces 22 are aligned vertically when assembled.
- the inclined surface 4 contacts the inclined surface 5, both having substantially the same angle, the inclined surface 4 moves downwardly following the direction of the inclined surfaces 4, 5 until the fourth arm back surface 74 of the following construction panel 1 contacts the surface 46 of the first construction panel 2.
- This ensures that the chamber 102 formed between the top portion 30 of the first construction panel 2 and the bottom portion 60 of the following construction panel 1 is closed. This is advantageous for mounting on an extern wall to avoid penetration of water towards the underlying wall, even in situations where there is a lot of wind.
- the following construction panel 1 is kept in position three-dimensionally.
- the X-direction is realised in the direction towards the wall by the contact between the extension surface 70 and the first arm front surface 32, as well as the contact between the fourth arm back surface 74 and the surface 46.
- the X-direction away from the wall is realised by positioning surface 4 being in contact with surface 5.
- the latter also realises the downwards Y-direction.
- the upwards Y-direction is realised by fixing the following construction panel 1 to the wall or a construction on the wall. The latter is also fixing the following construction panel 1 in the Z-direction.
- FIG. 1c Figure 3a and Figure 3b , assembling a construction panel 1 on an identical construction panel 2 will be described in more detail for lap mounting and thus for building a lap siding on a wall.
- Figure 3a illustrates two construction panels sliding into assembled state (lap siding), whereas Figure 3b shows the end of this process where the two panels are finally assembled.
- mounting construction panels 1, 2 on a wall is done starting at the bottom of a wall and building up upwards.
- the first construction panel 2 is mounted to the wall similar as discussed above for flush mounting.
- a following construction panel 1 is brought in position above the first construction panel 2.
- a chamber 103 formed between the top portion 30 op the first construction panel 2 and the bottom portion 60 of the following construction panel 1 is closed.
- boundaries are made by the contact between the extension surface 70 of the following construction panel 1 and the front surface 22 of the first construction panel 2, and also by the contact between the inclined positioning surface 4 of the following construction panel 1 and the first arm end surface 6 of the first construction panel 2. Similar as for flush mounting, this is advantageous for mounting on an underlying wall to avoid penetration of water, even in situations where there is a lot of wind.
- the X-direction is realised in the direction towards the wall by the contact between the extension surface 70 and the front surface 22.
- the X-direction away from the wall is realised by positioning surface 4 being in contact with the first arm top surface 6.
- the latter also realises the end position in the downwards Y-direction.
- the upwards Y-direction is realised by fixing the following construction panel 1 to the wall or a construction on the wall. The latter is also fixing the following construction panel 1 in the Z-direction.
- the construction panel 1 contains several inclined planes, meant for interlocking construction panels 1, such as the first arm end surface 6 at the first assembly position 36, the surface 5 at the second assembly position 59, and the positioning surface 4 at the third arm. These planes form substantially the same angle with the front and back surfaces 22, 24 of the front portion 20. Preferably, this angle is between 30° and 60°.
- the third section 54 of the first construction panel 2 receives the slot 78 of the following construction panel 1.
- the second assembly position 59 is used: the positioning surface 4 of the following construction panel 1 rests on the inclined guiding surface 5 of the second arm 8. Moreover, the protrusion 3 of the following construction panel 1 seals the whole system by contacting the first arm front surface 32.
- An air chamber 102 is formed between the two construction panels 1, 2. The aim of this air chamber is to prevent moisture from further creeping up and contacting the underlying surface.
- flush mounting there are two particular advantages to flush mounting.
- the choice between first and second assembly position 36, 59 is in essence a choice between two vertical positions.
- flush mounting helps reducing the material needed, i.e. the number of construction panels needed for covering the underlying surface.
- the second advantage is an extra aesthetic effect.
- the two construction panels 1, 2 interlock through different contact lines.
- the positioning surface 4 of the third arm 9 of the following construction panel 1 is received by the first assembly position 36 of the first construction panel 2 which has an inclined gliding surface 6,
- a third contact is formed by the protrusion 3 of the following construction panel 1 against the front surface 22 of the first construction panel 2.
- the fourth arm back surface 74 front of the following construction panel 1 does not make contact with the front surface 22 of the front portion 20 of the first construction panel 2.
- Protrusion 3 has several functions. Firstly, the protrusion facilitates installing the construction panels 1 whereas direct contact between the two construction panels 1, 2 at this point would make interlocking more difficult. Secondly, the positioning of protrusion 3 at the lower end of construction panel 1 at a lower point between the panels as compared to a direct contact helps to avoid intrusion of moisture and increases the level of wind resistance.
- the cross section of the protrusion can become a semicircle
- the gradual decrease of the thickness of the fourth arm 10 can be replaced by a slight bending or a local thickness decrease, etc.
- one of the main advantages of the present invention lies in the fact that the resulting overall thickness of construction panel 1 does not require much space especially when the overall thickness of the construction panel 1 is compared to the predetermined thickness 26 of the front portion 20.
- one of the described embodiments of the present invention has an overall thickness which is maximum four times the predetermined thickness 26 of the front portion, which is an advantage when construction panels need to be installed in a confined space where loss of space needs to be reduced.
- the present invention is that it can be manufactured in a wide range of materials.
- the present invention is manufactured in, but not limited to, metal (aluminium, stainless steel, etc.) or polymers.
- Construction panels typically can have a length of several meters. However, a wall can be longer requiring a combination of more than one panel next to each other. Typically, neighbouring panels contact each other at their ends but no mechanism is applied for further interlocking.
- the construction panels include a laterally interlocking mechanism
- Construction panels 80 and 81 are construction panels with over the largest part of their length the same cross section 90 as the one discussed in the embodiments of construction panel 1 but with on the one end equipped with a tongue 84 as shown on the figures for construction panel 80 and on the other end equipped with a groove 85 as shown on the figures for construction panel 81. For clarity on the drawings however, only the end with the tongue 84 is shown for construction panel 80 and the end with the groove 85 is shown for construction panel 81.
- the tongue 84 on one end of the construction panels 80, 81 is an extension extending on the overall cross section 90 of the construction panel with a thickness 86 which is thinner than the thickness 26 of the front portion 20 of the construction panel. In a preferred embodiment the thinner tongue is centered on the thicker part of the construction panel.
- a first part of the tongue 84 is extending on the front portion 20 and the fourth arm 10 forming a first part of the tongue parallel with the front surface 22 of the construction panel.
- a second part of the tongue 84 is formed in the top portion of the construction panel. The second part extends on the first arm of the top portion of the construction panel. This second part of the tongue 84 ensures that also in flush mounting there is no gap between two construction panels.
- the resulting tongue 84 has thus a first part 92 parallel with the front surface, subsequently an inclined part 89 following the first part of the first arm and ending with a part 94 parallel with the first arm front surface.
- the groove is not formed on the second arm, nor on the third arm.
- the groove 85 on the opposite end of the construction panels 80, 81 also has a first part formed in the front portion 20 and the fourth arm 10 of the construction panel.
- the cross section of the groove is parallel to the front surface 22 as can be best seen in figure 8 .
- the width 96 of the groove corresponds to the width 86 of the tongue 84 on the opposite side of the construction panel.
- the depth 96 of the groove corresponds to the length 97 of the tongue 84 on the opposite side of the construction panel.
- the groove 85 has a second part formed similar as the groove on the first arm. This second part first has an inclined part 88 following the first arm and ends with a part 93. Over the depth 96 where the end of the construction panel has a groove 85, the preferred embodiment has no second arm. Further, at the panel end containing the groove, part of the material of the back surface 24 is removed or alternatively not formed creating a recess 87. As will be explained in more detail below this feature allows an easier installation of the construction panels.
- the construction panel 80, 81 can be produced, among other techniques, by extrusion.
- groove 85 , tongue 84 and recess 87 are made using techniques such as, but not limited to, milling in a step after extrusion of the construction panel.
- mounting construction panels 80 and 81 on a wall is done starting from the right to the left, mounting the panels vertically on lower panels is described above.
- Construction panel 80 is first mounted to the wall. Subsequently, the second panel 81 is brought in position for installation.
- recess 87 turns out to be useful as it allows panel 81 to be lifted above a top portion of an already installed construction panel in a previous row when sliding to the right into position as shown in figure 6 .
- the inclined part 89 and offset part 94 are moving in the recess when the construction panel 81 is laterally moved towards construction panel 80. Once laterally in the right position, the panel 81 is then lowered as illustrated in figure 7 and mounted on a lower panel or other connection technologies known in the art.
- the above described construction panels with the cross section of one of the described embodiments and the lateral tongue-groove mechanism as described above provides several advantages.
- the specific shape of the construction panel is designed to provide a stable and easy mounting. Through the use of multiple contact lines, air chambers and gliding planes, degrees of freedom are severely reduced, resulting in wind- and waterproof construction panels.
- a lateral interacting mechanism further excludes any eventual possibility of lateral movement of the panels.
- an assembled wall will have no gaps. This is not only advantageous from a technical point of view but provides also a positive effect on the overall aesthetic of a resulting wall.

Description
- The present invention relates to a construction panel for assembling with other of such panels, and more particularly to a construction panel for selectively mounting in lap siding and flush siding on a wall.
- The present invention further relates to a system for building selectively lap siding and flush siding on a wall.
- Systems for covering walls and columns are known. Such systems often comprise assembly of construction panels. Such construction panels typically contain a longitudinal flat surface and a top and bottom portion which are arranged to interact with identical or similar panels. In such systems often different construction panels are provided for lap siding of walls and for flush siding of walls. This has a disadvantage in production because often small volumes have to be produced. This is also disadvantageous for the amount of stock because more construction panels will have to be kept in stock. Thus at the end, this is a costly way of offering products to the market.
- Systems are known which provide an answer to these issues.
US2642968 discloses panel members which may be used to simulate the appearance of lap siding or may be used to simulate sheeting or other wall structure wherein the panels have the appearance of uniform thickness throughout. The panel members are made of thin metal sheets and have saw tooth-like flange portions extending along the top and the bottom of each panel. These saw tooth-like flange portions allow the panels to snap into position in two different arrangements to a channel-shaped studding. A similar system is disclosed inUS4231206 . This document discloses a construction panel which comprises both at the top and bottom parts of the panel a channel and an adjacent tongue which extends outwardly from the channel. The shape of the channel is such that it can receive the tongue of an adjacent panel for assembling panels to build up siding. The panels can be combined in two different arrangements to form selectively flush siding or lap siding. The panels are made of thin sheet metal. -
US4122643 discloses a construction panel which has first and second engaging portions on top and a single engaging portion at the bottom. The single engaging portion is adapted to engage either the first or second engaging portion of an adjacent panel so that the panels can be disposed in lap or flush relation as desired. -
US2009/0094914 discloses a construction panel including a first side and a second side. A first engagement feature is disposed on or near the first side and a second engagement feature is disposed on or near the second side. The second engagement feature is disposed to selectively frictionally engage with the first engagement feature of another similar panel. - All these systems known in the art for selectively assembling in flush siding and lap siding still have several disadvantages. Sheet metal panels are often damaged during handling or assembling, and also, even if they are mounted on a wall perfectly, they are easily damaged afterwards. Another disadvantage of the known systems is that they add a relative large thickness to the wall. The known systems also provide limited material and finishing options which make these systems not very attractive.
- It is therefore an aim of the present invention to provide an improved construction panel and corresponding system for selectively building in flush siding or lap siding on a wall which is more compact, more damage-proof, easier to install and producible in a wide range of materials and finishes.
- This aim is achieved according to the invention with a construction panel incorporating a front portion, a top portion, comprising a first arm and a second arm, and a bottom portion, comprising a third and a fourth arm showing the technical characteristics of the first independent claim.
- The first arm comprises a first assembly position and the second arm comprises a second assembly position. The third arm comprises a positioning surface for interacting selectively on a first or second assembly position of a second similar construction panel in respectively lap mounting or flush mounting. This provides the user a choice between two ways of mounting. The fourth arm disposes of a protrusion which facilitates installation of the construction panels and avoids intrusion of moisture and wind. By the structure of a fourth arm with an aligned front surface and an extension surface which makes contact with the front surfaces in both mountings, the structure ensures overlap between two subsequent panels in both mounting methods and a good contact on a front surface avoiding intrusion of moisture and wind.
- In one embodiment, the distance between the front surface of the construction panel and the front surface of the first arm is equal to the distance between the former front surface and the extension surface on the back side of the protrusion. As an effect, all visible front surfaces lie in the same plane, which gives a pleasant aesthetic view.
- In further embodiments, the first or second arm of the construction panel comprises guiding means for guiding another construction panel towards the first or the second assembly position for lap or flush mounting respectively. The presence of these guiding means leaves no possibility for misalignment and facilitates mounting of the panels.
- In still a further embodiment, the third arm of the construction panel is equipped with guiding means for guiding the positioning surface on the third arm towards the first or the second assembly position of an underlying construction panel for lap or flush mounting respectively. This again facilitates mounting of the panels.
- In one embodiment, the guiding means of the third arm comprise a slot for encompassing a projection of the second arm of an underlying construction panel. This projection has a width corresponding to that of the slot. The advantage lies in a firmer and easier installation of the panels.
- In one embodiment, the first assembly position on the first arm and the second assembly position on the second arm both have an inclined surface for receiving the positioning surface of the third arm of a second construction panel wherein the inclined surfaces and the positioning surface are substantially parallel, allowing easier installation of the panels. The inclined surfaces ensure that during installation a panel moves towards its end position and thus that the protrusion on the fourth arm is in contact with the front surfaces.
- In a further embodiment, the construction panel further comprises in the longitudinal direction on one side a groove and at the opposite side a tongue. This lateral interacting mechanism provides a stable and easy mounting, excludes any lateral movement of the panels and shows no gaps between the panels.
- It is another aim of the present invention to provide a method for building selectively lap siding and flush siding on a wall using construction panels as described above. This method of building lap siding or flush siding has the advantage that the user can mount in the two mounting methods without compromising on the case of installation.
- This aim is achieved according to the invention with a method comprising the steps of the independent method claim.
- It is another aim of the present invention to provide a system.
- This aim is achieved according to the invention with a system comprising the technical characteristics of the independent system claim. The advantage of the claimed system is that in an easy installation process, a wall in lap mounting or flush mounting can be created which always provides a perfect contact on the front surfaces avoiding intrusion of moisture and wind.
- In one embodiment of the invention, the construction panel comprises an identical cross section, comprising a front portion, top portion and bottom portion, over a relatively long length in a longitudinal direction. The top portion is not aligned with the front portion. In the longitudinal direction, the construction panel comprises at one end of a tongue and at the opposite end of the panel of a groove. Both tongue and groove interact with a subsequent construction panel. The groove comprises a recess arranged to receive at least a portion of the tongue of the top portion of a subsequent construction panel, when this subsequent construction panel is positioned at an offset of the first construction panel. The effect is such that using an offset permits easier installation of the panels: once laterally in the right position, the panel can be lowered and mounted on the underlying panel.
- For a better understanding of the present invention, reference will now be made, by way of example only, to the accompanying drawings.

- Referring to
Figure 1a, Figure 1b and Figure 1c , cross sections of aconstruction panel 1 and anidentical construction panel 2 in accordance with an embodiment of the present invention are shown.Construction panel 1 is produced by extrusion. Therefore, the cross section ofconstruction panel 1 is representative for the whole length of the panel. In alternative embodiments,construction panel 1 may be produced by a different process known in the art such as for example injection molding. In still another alternative embodiment, the construction panel may not have an identical cross section over the whole length of theconstruction panel 1 as will be discussed in more detail below in the paragraph where the lateral interacting mechanism is discussed. -
Construction panel 1 comprises afront portion 20 having afront surface 22 and aback surface 24, and a firstpredetermined thickness 26 between thefront surface 22 and theback surface 24. Theconstruction panel 1 further comprises atop portion 30 and abottom portion 60.Figure 4 illustrates thetop portion 30 in an enlarged view.Top portion 30 comprises afirst arm 7 and asecond arm 8. Thefirst arm 7 extends on theback surface 24 making a corner over about 90 degrees towards the outside of theconstruction panel 1 and forming a firstarm front surface 32 and a first arm backsurface 33 substantially parallel to front thefront surface 22 and theback surface 24. Thefirst arm 7 further comprises a firstarm end surface 6 angled with respect to the firstarm front surface 32 to form an inclined gliding plane.First arm 7 serves as afirst assembly position 36. Theangle 38 between the firstarm front surface 32 and the firstarm end surface 6 is smaller than 90 degrees. This has the advantage that an interactingconstruction panel 1 during assembling will easily position itself on thefirst assembly position 36 as will be described in more detail below. Theangle 38 is preferably between 30 and 60 degrees. In the embodiment ofFigure 4 , theangle 38 is about 45 degrees. - The
second arm 8 extends on the first arm backsurface 33 making a corner over about 90 degrees towards the outside of theconstruction panel 1 and forming afirst surface 42 and asecond surface 43 substantially parallel to thefront surface 22 and theback surface 24. This portion can be called thefirst section 52 of the second arm. Thesecond arm 8 then turns back over about 45 degrees forming athird surface 44 and afourth surface 5. In alternative embodiments this angle may be different from 45 degrees. Thethird surface 44 is angled with respect to thefirst surface 42 and the fourth surface is angled with respect to thesecond surface 43. This angled portion can be called thesecond section 56 of thesecond arm 8. Thesecond arm 8 then turns again to direct athird section 54 of thesecond arm 8 in the same direction as thefirst section 52 but closer towards thefront surface 22 forming afifth surface 46 and asixth surface 47. The fifth andsixth surfaces Figure 4 , the second predetermined thickness 55 of thethird section 54 of thesecond arm 8 is substantially the same as the firstpredetermined thickness 26 of thefront portion 20. In alternative embodiments, the second predetermined thickness 55 may be more or less than the firstpredetermined thickness 26. Thesecond arm 8 ends with anend surface 48. Theend surface 48 is in the embodiment ofFigure 4 slightly rounded. This has the advantage that thethird section 54 will easily enter a slot during assembly as will be discussed in more detail below. It is further noted thatfourth surface 5 of thesecond arm 8 is parallel to the firstarm end surface 6 of thefirst arm 7. This has the advantage that a portion of an interactingconstruction panel 1 which is designed to interact with the firstarm end surface 6 will also interact optimally with thefourth surface 5. This will be illustrated in more detail below when the interaction of two construction panels is discussed. Thesecond arm 8 and especially thesecond section 56 of thesecond arm 8 serves as asecond assembly position 59. -
Figure 5 illustrates thebottom portion 60 in an enlarged view. Thebottom portion 60 comprises athird arm 9. Thethird arm 9 extends on theback surface 24 making a corner over about 90 degrees towards the outside of theconstruction panel 1 and forming a thirdarm front surface 62 and a third arm backsurface 63 substantially parallel to thefront surface 22 and theback surface 24. Thethird arm 9 further comprises aslot surface 66 substantially perpendicular to theback surface 24 and extending from theback surface 24 towards the thirdarm front surface 62. A third armtop surface 64 is extending on theback surface 24 and angled over anangle 68 with respect to theback surface 24. The third armtop surface 64 forms the connection between theback surface 24 and the third arm backsurface 63. In the embodiment ofFigure 5 the angle is about 45 degrees. In alternative embodiments, theangle 68 may be more or less than 45 degrees. Thethird arm 9 further comprises apositioning surface 4 starting at the end of the thirdarm front surface 62 and forming anangle 69 with respect to the thirdarm front surface 62. Thethird arm 9 ends with anend surface 67. Theend surface 67 is in the embodiment ofFigure 5 slightly rounded and connects the end ofpositioning surface 4 with the end of the third arm backsurface 63 in a rounded way. This has the advantage that thethird arm 9 will be received smoothly in an interaction portion of acorresponding construction panel 1 during assembly. - The
bottom portion 60 further comprises afourth arm 10. Thefourth arm 10 comprises a fourtharm front surface 72 which is an extension of thefront surface 22 in the same plane and forming in practice thus a single surface. The fourth arm further comprises a fourth arm backsurface 74 slightly angled with respect to theback surface 24 towards thefront surface 72. Theangle 76 is preferably between 0 and 10 degrees. In the embodiment ofFigure 5 , the angle is about 2 degrees. In an alternative embodiment theangle 76 is zero and the fourth arm backsurface 74 is parallel to the fourth anglefront surface 72. The fourth arm backsurface 74 together with the thirdarm front surface 62 and theslot surface 66 form aslot 78. Thefourth arm 10 further comprises at the end a protrusion 3.Theprotrusion 3 extends on the fourth arm backsurface 74 away from the fourtharm front surface 72 and in a direction perpendicular to the fourtharm front surface 72 which is the X-direction illustrated on the drawing. The extension ends in anextension surface 70. Theextension surface 70 is substantially parallel to thefront surface 22 and is positioned in substantially the same plane as theback surface 24. Thefourth arm 10 ends with anend surface 71. Theend surface 71 is connecting the end of the fourtharm front surface 72 and the outside end of theextension surface 70. Theend surface 71 is angled with respect to the fourtharm front surface 72 towards the inside of theconstruction panel 1. The angle 75 is smaller than 90 degrees. This has the advantage that, when the construction panel is assembled, water will be guided to the front surface of theconstruction panel 1. - The
construction panels 1 can be mounted according to two different arrangements. Either the visible front surfaces 22 of allconstruction panels 1 are mounted substantially in the same plane (this is called "flush mounting"), or thefront surfaces 22 of allconstruction panels 1 are arranged cascade-like (this is termed "lap mounting"). According to the latter arrangement, eachconstruction panel 1 is on thetop portion 30 partly covered by a part of thebottom portion 60 of anotherconstruction panel 1, and allconstruction panels 1 are slightly tilted. This will be illustrated in more detail below. Referring now toFigure 1b andFigure 2 , assembling aconstruction panel 1 on anidentical construction panel 2 will be described in more detail for flush mounting and thus for building a flush siding on a wall. Mountingconstruction panels Figure 1b , thefirst construction panel 2 is mounted to the wall. This can for example be done by providing one or more screws through thesecond section 52 of thetop portion 30 of theconstruction panel 2. In other embodiments however the connection of the construction panel to the wall can be done by any other connecting technologies known in the art. In that way, surface 43 is connected to the wall or to a frame on the wall. Subsequently, a followingconstruction panel 1 is brought in position above thefirst construction panel 2. The followingconstruction panel 1 is then moved downwards such that theslot 78 of the followingconstruction panel 1 moves over thethird section 54 of thefirst construction panel 2. This relative movement proceeds until theinclined positioning surface 4 of the followingconstruction panel 1 comes into contact with theinclined surface 5 of thefirst construction panel 2. The width of theslot 78 is designed such that it corresponds to the width 55 of thethird section 54. During the downwardsmovement extension surface 70 of the followingconstruction panel 1 is brought into contact with the firstarm front surface 32. This interconnection of thetop portion 30 and thebottom portion 60 has several advantages. First, when moving downwards, theinclined surface 4 of the followingconstruction panel 2 creates guidance for guiding theslot 78 towards thethird section 54. Secondly, theinclined surface 74 of the followingconstruction panel 1 avoids that thethird section 54 of the followingconstruction panel 1 gets stuck in theslot 78. Thirdly, theextension 3 and especially theextension surface 70 contacting the firstarm front surface 32 ensures that the differentfront surfaces 22 are aligned vertically when assembled. Fourthly, when theinclined surface 4 contacts theinclined surface 5, both having substantially the same angle, theinclined surface 4 moves downwardly following the direction of theinclined surfaces surface 74 of the followingconstruction panel 1 contacts thesurface 46 of thefirst construction panel 2. This ensures that thechamber 102 formed between thetop portion 30 of thefirst construction panel 2 and thebottom portion 60 of the followingconstruction panel 1 is closed. This is advantageous for mounting on an extern wall to avoid penetration of water towards the underlying wall, even in situations where there is a lot of wind. In the end position, the followingconstruction panel 1 is kept in position three-dimensionally. The X-direction is realised in the direction towards the wall by the contact between theextension surface 70 and the firstarm front surface 32, as well as the contact between the fourth arm backsurface 74 and thesurface 46. The X-direction away from the wall is realised by positioningsurface 4 being in contact withsurface 5. The latter also realises the downwards Y-direction. The upwards Y-direction is realised by fixing the followingconstruction panel 1 to the wall or a construction on the wall. The latter is also fixing the followingconstruction panel 1 in the Z-direction. - Referring now to
Figure 1c ,Figure 3a and Figure 3b , assembling aconstruction panel 1 on anidentical construction panel 2 will be described in more detail for lap mounting and thus for building a lap siding on a wall.Figure 3a illustrates two construction panels sliding into assembled state (lap siding), whereasFigure 3b shows the end of this process where the two panels are finally assembled. Similar as for flush mounting, mountingconstruction panels Figure 1c , thefirst construction panel 2 is mounted to the wall similar as discussed above for flush mounting. Subsequently, a followingconstruction panel 1 is brought in position above thefirst construction panel 2. Then, the third arm backsurface 63 is brought into contact withsurface 46 and the followingconstruction panel 1 is further moved downwards along this contact plane. This will continue until thethird arm 9 starts to move inwardly when the third armtop surface 64 moves towardssurface 44 andpositioning surface 4 contacts firstarm end surface 6 to move towards the end position as illustrated inFigure 1c andFigure 3a and Figure 3b . This interconnection has again several advantages. Firstly, surface 46 on thefirst construction panel 2 provides an easy accessible initialisation surface for making contact with the followingconstruction panel 1. Secondly, theinclined surfaces chamber 103 formed between thetop portion 30 op thefirst construction panel 2 and thebottom portion 60 of the followingconstruction panel 1 is closed. As discussed above, boundaries are made by the contact between theextension surface 70 of the followingconstruction panel 1 and thefront surface 22 of thefirst construction panel 2, and also by the contact between theinclined positioning surface 4 of the followingconstruction panel 1 and the firstarm end surface 6 of thefirst construction panel 2. Similar as for flush mounting, this is advantageous for mounting on an underlying wall to avoid penetration of water, even in situations where there is a lot of wind. Once fixed on top, similar as for flush mounting, the followingconstruction panel 1 is kept in position three-dimensionally. The X-direction is realised in the direction towards the wall by the contact between theextension surface 70 and thefront surface 22. The X-direction away from the wall is realised by positioningsurface 4 being in contact with the first armtop surface 6. The latter also realises the end position in the downwards Y-direction. The upwards Y-direction is realised by fixing the followingconstruction panel 1 to the wall or a construction on the wall. The latter is also fixing the followingconstruction panel 1 in the Z-direction. - As discussed above, the
construction panel 1 contains several inclined planes, meant for interlockingconstruction panels 1, such as the firstarm end surface 6 at thefirst assembly position 36, thesurface 5 at thesecond assembly position 59, and thepositioning surface 4 at the third arm. These planes form substantially the same angle with the front and back surfaces 22, 24 of thefront portion 20. Preferably, this angle is between 30° and 60°. - When arranged in flush mounting as discussed above, two
construction panels 1 interlock via various contact lines creating afirst air chamber 102. Thethird section 54 of thefirst construction panel 2 receives theslot 78 of the followingconstruction panel 1. Thesecond assembly position 59 is used: the positioningsurface 4 of the followingconstruction panel 1 rests on the inclined guidingsurface 5 of thesecond arm 8. Moreover, theprotrusion 3 of the followingconstruction panel 1 seals the whole system by contacting the firstarm front surface 32. - These multiple contacts in combination with fixation to an underlying surface via orifices applied in the
second section 56 of thesecond arm 8 preclude further motion of the construction panel when mounted. Anair chamber 102 is formed between the twoconstruction panels - There are two particular advantages to flush mounting. First, there is a non-negligible economic advantage: part of the first
arm front surface 32 is still visible in flush mounting. The choice between first andsecond assembly position - When arranged in lap mounting as discussed above, the two
construction panels positioning surface 4 of thethird arm 9 of the followingconstruction panel 1 is received by thefirst assembly position 36 of thefirst construction panel 2 which has aninclined gliding surface 6, A third contact is formed by theprotrusion 3 of the followingconstruction panel 1 against thefront surface 22 of thefirst construction panel 2. It should be noted here that the fourth arm backsurface 74 front of the followingconstruction panel 1 does not make contact with thefront surface 22 of thefront portion 20 of thefirst construction panel 2. -
Protrusion 3 has several functions. Firstly, the protrusion facilitates installing theconstruction panels 1 whereas direct contact between the twoconstruction panels protrusion 3 at the lower end ofconstruction panel 1 at a lower point between the panels as compared to a direct contact helps to avoid intrusion of moisture and increases the level of wind resistance. - It will also be appreciated that changes can be made to the above discussed embodiments to alter the overall appearance of the
construction panel 1. For example, the cross section of the protrusion can become a semicircle, the gradual decrease of the thickness of thefourth arm 10 can be replaced by a slight bending or a local thickness decrease, etc. - Although the present invention is described as a thick and robust construction panel wherein the front portion is preferably between 4 and 7mm, one of the main advantages of the present invention lies in the fact that the resulting overall thickness of
construction panel 1 does not require much space especially when the overall thickness of theconstruction panel 1 is compared to thepredetermined thickness 26 of thefront portion 20. Indeed, one of the described embodiments of the present invention has an overall thickness which is maximum four times thepredetermined thickness 26 of the front portion, which is an advantage when construction panels need to be installed in a confined space where loss of space needs to be reduced. - One of the advantages of the present invention is that it can be manufactured in a wide range of materials. In present embodiments, the present invention is manufactured in, but not limited to, metal (aluminium, stainless steel, etc.) or polymers.
- Although only a limited amount of the embodiments are described, it will be understood that regarding this mechanism, various changes may be made in form, shape, angle and size, which result in the same effect as described above.
- Referring now to
Figures 6 to 11 , a lateral assembly of construction panels will be described in more detail. Construction panels typically can have a length of several meters. However, a wall can be longer requiring a combination of more than one panel next to each other. Typically, neighbouring panels contact each other at their ends but no mechanism is applied for further interlocking. In the embodiment offigures 6 to 11 the construction panels include a laterally interlockingmechanism Construction panels same cross section 90 as the one discussed in the embodiments ofconstruction panel 1 but with on the one end equipped with atongue 84 as shown on the figures forconstruction panel 80 and on the other end equipped with agroove 85 as shown on the figures forconstruction panel 81. For clarity on the drawings however, only the end with thetongue 84 is shown forconstruction panel 80 and the end with thegroove 85 is shown forconstruction panel 81. - The
tongue 84 on one end of theconstruction panels overall cross section 90 of the construction panel with a thickness 86 which is thinner than thethickness 26 of thefront portion 20 of the construction panel. In a preferred embodiment the thinner tongue is centered on the thicker part of the construction panel. A first part of thetongue 84 is extending on thefront portion 20 and thefourth arm 10 forming a first part of the tongue parallel with thefront surface 22 of the construction panel. A second part of thetongue 84 is formed in the top portion of the construction panel. The second part extends on the first arm of the top portion of the construction panel. This second part of thetongue 84 ensures that also in flush mounting there is no gap between two construction panels. The resultingtongue 84 has thus afirst part 92 parallel with the front surface, subsequently aninclined part 89 following the first part of the first arm and ending with apart 94 parallel with the first arm front surface. In this embodiment the groove is not formed on the second arm, nor on the third arm. - The
groove 85 on the opposite end of theconstruction panels front portion 20 and thefourth arm 10 of the construction panel. In this first part of thegroove 85 the cross section of the groove is parallel to thefront surface 22 as can be best seen infigure 8 . Thewidth 96 of the groove corresponds to the width 86 of thetongue 84 on the opposite side of the construction panel. Thedepth 96 of the groove corresponds to the length 97 of thetongue 84 on the opposite side of the construction panel. Thegroove 85 has a second part formed similar as the groove on the first arm. This second part first has aninclined part 88 following the first arm and ends with apart 93. Over thedepth 96 where the end of the construction panel has agroove 85, the preferred embodiment has no second arm. Further, at the panel end containing the groove, part of the material of theback surface 24 is removed or alternatively not formed creating arecess 87. As will be explained in more detail below this feature allows an easier installation of the construction panels. - As described above, the
construction panel groove 85 ,tongue 84 andrecess 87 are made using techniques such as, but not limited to, milling in a step after extrusion of the construction panel. - Referring to
figures 6 and 7 , mountingconstruction panels Construction panel 80 is first mounted to the wall. Subsequently, thesecond panel 81 is brought in position for installation. Here, the presence ofrecess 87 turns out to be useful as it allowspanel 81 to be lifted above a top portion of an already installed construction panel in a previous row when sliding to the right into position as shown infigure 6 . By the positioning and dimensioning of the recess theinclined part 89 and offsetpart 94 are moving in the recess when theconstruction panel 81 is laterally moved towardsconstruction panel 80. Once laterally in the right position, thepanel 81 is then lowered as illustrated infigure 7 and mounted on a lower panel or other connection technologies known in the art. - The above described construction panels with the cross section of one of the described embodiments and the lateral tongue-groove mechanism as described above provides several advantages. The specific shape of the construction panel is designed to provide a stable and easy mounting. Through the use of multiple contact lines, air chambers and gliding planes, degrees of freedom are severely reduced, resulting in wind- and waterproof construction panels. A lateral interacting mechanism further excludes any eventual possibility of lateral movement of the panels. Furthermore, an assembled wall will have no gaps. This is not only advantageous from a technical point of view but provides also a positive effect on the overall aesthetic of a resulting wall.
