[0037] It is to be noted that the figures are given by way of exemplary examples and are not limiting to the disclosure.

[0038] FIG. 1 gives a schematic exploded view representation of a partition wall system 1. The partition wall system 1 comprises at least two posts 2 that can be erected uprightly. Further, the partition wall system 1 comprises at least one profile 3, that is removable connectable to two adjacent vertical posts 2. In the example of FIG. 1, there are three horizontal profiles 3 between the left and middle vertical posts 2 and there are two horizontal profiles 3 between the right and middle vertical posts 2.More or less horizontal profiles can be provided. The horizontal profiles 3 are connected to the posts 2 one above the other, such that there is a gap 4 between them. Between an upper and a lower profile 3, a panel 5 can be provided. The panel 5 may engage the lower profile 3 as well as the upper profile 3 and thus may fill the gap 4 between the respective profiles 3.

[0039] The posts 2, or so-called upright posts or vertical posts, can be erected between a floor 6 and a ceiling 7, or can be fixated to a floor 6 only. For fixating the post 2 to the floor 6 and/or the ceiling 7, a fixation element 8 is provided. The fixation element 8 can be an adjustable foot 8, comprising a post insert 9 and a foot base 10. FIG. 4 shows the fixation element 8 in exploded view. The post insert 9 has a cross-sectional shape corresponding to the cross-section of the post 2, at least to the cross-section of an upper end or a lower end of the post 2. In the post insert 9, a bore 11 is provided in which the foot base 10, in particular a threaded body 12 can be screwed. The bore 11 can be provided with a corresponding thread, or can be without thread. The bore 11 can be a through bore, as shown in FIG. 4, or can be a bore having a closed end. By adjusting the foot base 10 with respect to the post insert 9, the height of the post 2 can be adjusted. The foot base 10 can be a plastic or metallic piece, the post insert 9 is advantageously of a plastic material, but may have a metallic threaded insert in the bore 11 for receiving the threaded body of the foot base 10. The foot base 10 further is provided with two slit openings 13. Screws may be inserted through these openings for fixating the foot base 10 to the floor 6 or ceiling 7. Alternatively, such screws may be omitted. Alternative embodiments of an adjustable foot are possible, e.g. a foot as insert in the vertical post can be adjustable by means of a pin-in-hole connection, or via a rack-and-pinion system or via a finger cooperating with a saw-tooth, etc.

[0040] The profiles 3 can be connected to the posts 2 by means of a connecting element 14, the post 2 is advantageously provided with a corresponding connection element 15. Various examples of the connection elements 14, 15 are possible. For example, the connection element 14 may be provided as a protrusion that fits in a cut-out connection element 15 of the post 2. Alternatively, the connection element 14 of the profile 3 may be a hook that can be hooked over or in a corresponding protrusion or opening of the post 2. Alternatively, the connection element 14 can be a pin with a head, a mushroom shaped element, that can be inserted into a key-hole shaped opening of the post 2, as shown in FIG. 2. An advantage of the mentioned examples is that no tools or instruments are required to connect the profiles 3 to the posts 2. The opposite configurations may also be possible, for example, in that the post may be provided with a pin as connection element 15 that may fit into an opening of the profile 3. In the example shown in FIG. 1, the connection element 14 is schematically represented as well as the corresponding connection element 15 is also schematically represented. It may be evident that multiple connection elements are possible that allow for establishing a removable connection between the profile 3 and the post 2.

[0041] To align the connection elements 15 of the adjacent posts 2, the height of the posts 2 can be adjusted with the adjustable foot 8.

[0042] The profile 3 is advantageously of a hollow cross-section and may be made from metal, e.g. steel, it can thus be a steel rolled profile. The profile 3, as shown in the cross-section of FIG. 3, has in this example a cross-shaped cross-section. The cross-shaped cross-section comprises two protruding flanges 16, 17 and two protruding ribs 18, 19. Alternative shapes, such as a T-shape or an L-shape are also possible. Advantageously, the cross-section of the profile 3 is symmetrical with respect to a first symmetry axis S1, in use a vertical axis, such that the protruding flanges 16, 17 are symmetrical. In a further embodiment, the profile 3 can be symmetrical with respect to a second symmetry axis S2, in use, a horizontal axis. As such, the profile 3 can be easy to handle as then, the orientation as to how connect the profile 3 to the post 2 can be relatively free. More advantageously, the post 2 is of the same shape and/or has the same cross-section, preferably the same hollow cross-section as the profile 3. This may make manufacturing of the posts 2 and profiles 3 more simple, and more cost effective, as the same shape can be used for the profile as well as for the post. For example, in FIG. 2 is schematically illustrated that the profile 3 and the post 2 have the same shape. When the post 2 and the profile 3 have the same shape, the above description regarding the cross-section of the profile 3 is equally applicable to the cross-section of the post 2.

[0043] The protruding flange 16, 17 may provide for a support for the panel 5 that can be engaged to the profile 3. More particular, the rib 18, 19 may provide for engagement of the panel 5 to the profile 3. The panel 5, in particular the upper edge 20 and/or lower edge 21 can be provided with engagement elements 22, 23. The engagement elements 22, 23 of the upper and lower edge 20, 21 can be the same, but may be different as well. For example, the engagement element 23 of the lower edge 21 can be a protrusion fitting in a groove of the flange 16, while the engagement element 22 of the upper edge 20 can be a pin or click-finger fitting in an opening of the rib 19. In another example, both engagement elements 22, 23 can be the same, for example click-fingers engaging in openings of the ribs 19, 18. Here, the engagement elements 22, 23 are embodied the same, namely as magnetic elements connected to the upper edge 20 and the lower edge 21 of the panel respectively. However, the magnetic elements can be connected to the ribs 18, 19 as well. The magnetic elements 22, 23 can be connected to the outside of the panel 5 and/or profile 3, or can be mounted inside of the panel 5 and/or profile 3.

[0044] Advantageously, the profile 3 is from a magnetisable material, such as steel. Alternatively and/or additionally, the upper edge 20 and/or the lower edge 21 of the panel 5 can be of a magnetisable material as well. In an embodiment, the panel 5 comprises a frame 51 and a panel body 52. The upper edge 20 and the lower edge 21 may provide the frame 51. The frame 51 may further comprise side edges as well. The panel body 51 may be integral to the frame 51, as shown in the embodiment of FIG. 3, but may be separate from the frame and connectable to the frame. For example, the panel body 52 can be made from textile, plants, fabric, composite or plastic material, wood etc., and/or may comprise shelves, a cabinet or a display etc. Many variants of the panel or panel body are possible.

[0045] By providing magnetic elements 22, 23 as engagement elements, the engagement of the panel 5 to the profiles 3 can be relatively simple. The panel 5 is first supported on the flange 16 of the lower profile 3, preferably in the corner between the flange 16 and the rib 18. Then, the panel 5 can be rotated towards the upper profile 3 until the upper edge 20 of the panel 5 engages the rib 19. Due to the magnetic force of the magnetic elements 22, 23 a firm connection can then be established. At the opposite side of the profiles 3, another panel 5 may be engaged to the profiles 3 as well, as schematically indicated in FIG. 3.

[0046] The panel 5 may further be provided with side edges in a similar way as the upper edge 20 and the bottom edge 21. The side edges may then engage with arms of the posts 2 in a similar way as the upper and lower edges engage with the arms 18, 19 of the profile 3. In fact, when the profile and post have the same cross-section and the side edges of the panel are similar to the upper and lower edges, the section of the system shown in FIG. 3, made in a vertical plane, parallel to a post, is equally applicable to a possible section of the system in a horizontal plane through the panel, parallel to a horizontal profile.

[0047] The upper and lower edges of the panel may form the frame of the panel. If present, the frame may further comprise the side edges as well.

[0048] FIG. 5 shows a bottom view of an alternative connection element 14 for connection of the profile 3 to the post 2. Here, the connection element 14 comprises a plug 24 and the corresponding connection element 15 may comprise a pen 25. The plug 24 is insertable in a hollow end of the profile 3, and has a shape corresponding to the shape of the cross-section of the profile 3. Here, the shape of the plug 24 is approximately cross-shaped. The corresponding connection element 15 of the post 2, further comprises a through bore through which the pen 25 can extend. In case of a hollow shaped post, the through bore may be embodied as aligned openings in opposite sides of the post.

[0049] The pen 25 comprises here two pen parts 25a, 25b that are connectable to each other via screw thread. One pen part 25a is provided with a threaded rod 26 while the other pen part 25b is provided with a threaded bore in which the threaded rod can be screwn. Both pen parts 25a, 25b have the same or similar end shape, namely comprising a knob 27, a rejuvenation 28 and a rib 29 connected to a pen body 30. The rejuvenation 28 may have a smaller diameter than the pen diameter and may form a space between the knob 27 and the rib 29 Advantageously, the pen part 25a, 25b is integrally manufactured as a single piece part, e.g. from metal or composite.

[0050] The plug 24 can be provided with a transverse wall 31 in which an opening 32 is provided. Advantageously, the transverse wall 31 fits in the space between the knob 27 and the rib 29 provided by the rejuvenation 28. The opening 32 is preferably V-shaped such that finding the pen 25 can relatively easy, and upon moving the plug 24 downwardly over the pen 25, a tight connection can be obtained.

[0051] The posts 2 are in a beneficial manner provided with pre-bored bores 15 through with pen parts 25a, 25b can be inserted and can be connected to each other to form pen 25. As such, the pens 25 can be connected to the posts 2 at positions corresponding to a user’s preference. When the pens 25 are inserted to the posts 2, the profiles 3 can be mounted over the pens 25. In particular, the plugs 24 inserted in ends of the profiles 3 can be mounted over the pens 25. More in particular, the transverse wall 31 of the plug 24 can be mounted in the space formed by the rejuvenation 28.

[0052] The opening 32 in the transverse wall 31 may be key-hole shaped, as to tight-fitting the pen, in particular the rejuvenation 28, when in engaged position. Furthermore, the transverse wall 31 may have a slight inclination, an angle alpha between about 1 degree to about 10 degrees, preferably about 5 degrees, with respect to a plane perpendicular to a longitudinal direction L of the plug 24, as can be seen in FIG. 6.

[0053] Also shown in FIG. 6 is the securing between the panel 5 and the profile 3. This securing is obtained via a locking element 33, comprising click-fingers 34 for securing the connection between the panel 5 and the profile 3. The mere connection between the panel 5 and the profile 3 has already been established by means of the engagement elements 23, e.g. magnetic elements 23. For the purpose of a safe, reliable and secured connection, the locking element 33 is provided. The click-finger 34 is engageable in an opening 35 of the panel 5. The panel 5 is here provided with an upper edge 20 and a panel body 51 that has a depth D that is larger than the depth d of the upper edge 20, mutatis mutandis for the lower edge 21 as well. As such, a shoulder 52 is obtained, in this shoulder 52 openings 35 can be provided in which the click-finger 34 of the locking element 33 can click. By providing the panel body 51 with a depth D larger than the depth d of the upper edge 20, or lower edge 21, when engaged a recess 36 is obtained between the profile 3 and the panel body 51. In this recess, typically a finger of a user may fit which finger of the user can hold the panel 5 for engaging it to the profile 3. Also, when disengaging the panel 5, the user can push the click-finger 34 inward and as such, may undo the securing of the click-finger 34 to the opening 35 allowing the panel 5 to be removed from the profile 3.

[0054] FIG. 7 shows the locking element 33 in a perspective view. The locking element 33 is provided as a locking clip insertable into the plug 24. The plug 24, as well as the profile 3 is thereto provided with an opening 37 through which the locking clip 33 can be inserted to be tightly clipped to the plug 24. The plug 24 is provided with protrusions 38 that fit in recesses 39 of the clip 33. The recesses 39 are provided on two outwardly and downwardly extending legs 41. The locking clip 33 comprises a bridge 42 or base part from which the legs 41 extend downwardly. When moving the legs 41 towards each other, the recesses 39 may become free from the protrusions 38 and the clip 33 can be removed from the plug 24. Advantageously, the legs 41 have at their lower ends a transverse arm 43 for cooperation with the profile 3. The user may easily engage with the transverse arms 43 to move the legs 41 towards each other for disengaging the locking element 33 from the plug 24 and the profile 3.

[0055] More inwardly with respect to the legs 41, two fingers 44 extend downwardly from the bridge 42 of the locking clip 33. The downwardly extending fingers 44 are here embodied as legs as well, and are arranged for engagement with the panel 5. The bridge or base part 42 is in fact the upper part from which the legs 44 extend. By the legs 41, 44 extending from the base bridge 42, some elasticity is provided allowing some movement of the legs with respect to each other. Such elasticity and/or movement may provide for engaging and disengaging from the locking clip 33 to the profile 3 and/or the panel 5. The legs 44 end in the transversely extending click-fingers 34. Due to the L-shape of the configuration of the leg 44 with the click-finger 34, flexibility is provided to the locking element 33, allowing downward movement of the click-finger 34, and thus, disengagement of the click-finger 34 from the opening 35 in the panel 5. The locking element 33 not only provides for a secure and reliable connection of the panel 5 to the profile 3, but it is also designed as to be removable itself. This allows a large flexibility and versatility to the user of the wall system. In the example of the locking clip 33 shown in FIG. 7 and FIG. 8, the locking clip 33 is symmetrically with respect to a symmetry plane S coinciding with a longitudinal axis of the plug 24 of the profile connection element 14.

[0056] The locking clip 33 is in this example shown with two legs 44 and two fingers 41 downwardly extending from the bridge 42, allowing two panels 5, one panel 5 at each side of the profile 3, to be secured to the horizontal profile 3 at the same time. However, in another example, the locking clip 33 may comprise a single leg 44 and a single finger 41 for securing a panel 5 at one side of the horizontal profile 3 only. The locking clip 33 as shown in FIG. 6 and FIG. 7 may be manufactured by 3D-printing or by injection moulding in a composite plastic material.

[0057] FIG. 9 shows an other embodiment of the locking element 33 in a perspective view. The locking element 33 is provided as a locking insert insertable into the opening 37 of the horizontal profile 3 which is provided here as a rectangular opening 37. The insert 33 is here box-shaped and is engageable in a recess in the plug through the opening 37 in the profile 3. The insert 33 comprises a rectangular shaped base 42, from which legs 41 and fingers 44 extend downwardly as sides of the insert 33. The legs, fingers 41, 44 are here embodied as plate shaped sides of the box-shaped insert 33. Two legs 41 extend from two opposite edges of the base 42 and are arranged for cooperation with the profile 3. Two legs 44 extend from the other two opposite edges of the base 42 and are arranged for engagement with the panel 5. The legs 41 comprise click-fingers 60 and a transversely extending flange 43 at a lower end of the legs 41. The legs 41, 44 may thus form sides of the box-shaped insert 33. The click-finger 60 are arranged to engage an edge of the opening 37, as such securing the insert 33 to the horizontal profile 3. Advantageously, the legs 41 have at their lower ends a transverse arm 43. The user may easily engage with the transverse arms 43 to move the legs 41 towards each other for disengaging the locking insert 33 from the profile 3. The two other legs 44, oriented transversely with respect to the legs 41, have at their lower ends click-finger 34. The hook shape of the click finger 34 allows the click finger 34 to receive and secure the upper edge 20 or the lower edge 21 of the panel 5, depending on whether the insert 33 is inserted on a top side or a bottom side of the horizontal profile 3. The hook shape of the click-finger 34, especially an outward face 62 forming a slightly obtuse angle with an upper face 64, may allow some rotational movement to the panel 5, for example to allow the upper edge 20 of the panel 5 to be rotated towards the horizontal profile 3 when the lower edge 21 already engages the click finger 34. Also, the shape of the faces 62, 64 forming the click finger 34 may provide for engagement from a user that can push the click finger to engage or disengage from the panel 5. A click finger 34 engaged to the upper edge 20 of the panel 5 may however prevent the rotational movement allowed to the panel 5 by an other click finger 34 engaged to the lower edge 21 and vice versa. As such, the panel 5 can be fixedly engaged between multiple click fingers 34.

[0058] The locking clip 33 as shown in FIG. 9 may be provided from steel sheet, for example from spring steel providing some elasticity in the clip. In particular, the legs 41, 44 may have some elasticity with respect to the base 42 allowing engaging/disengaging to/from the respective recesses of the profile and/or the panel.

[0059] For example, a panel 5 may be provided with four recesses, one on each corner, to engage with four locking clips 33, two at a top side of the panel, and two at a bottom side of the panel. Alternatively, only a top side of the panel 5 may engage with the locking clips 33 to connect to the horizontal profile 3. A locking clip as shown in FIG. 7 may be used, or a locking clip 33 as shown in FIG. 9 may be used.

[0060] In an embodiment of the invention, the insert 33 may be used as the primary or only connection between the horizontal profile 3 and the panel 5. In other words, the insert 33 may function as engaging element 23, even though it remains possible to combine the insert 33 with, for example, magnetic elements 23.

[0061] As can be seen in the various examples, the partition wall system and all its components are configured as to be removable, disengageable, reusable, re-positionable etc. All connections provided between the components of the partition wall system are easy removable or loosenable without the need for any tools or instruments, by simply disconnecting or disengaging of connection elements or disengagement elements. Also, the locking element is easy insertable to the profile with a single hand and without tools. Thus the system is relatively simple and straightforward in use and can be easy modified, extended, adapted, customized etc. to the preferences of the user. For example, in one situation a straight wall is required in a certain colour, whereas for the next occasion the colour is to be different. It is then easy to remove the wall panels and to replace with panels in a different colour and/or colour pattern. In another example, in one occasion a floor to ceiling wall is required, whereas in the next occasion, a shoulder high partition is need. The upper panels can then simply be removed from the wall system. Lower panels may be replaced by cabinet- or shelve-shaped panels. In still another example, a wall system having posts not extending up to the ceiling, but ending e.g. a shoulder height can be sufficient while the wall system is configured in an L-configuration. At both sides of the posts and profiles panels can be mounted, giving versatility and flexibility at both sides of the wall system. Moreover, the elements of the partition wall system may be connected to each other without using any tools or instruments, namely tool-less. Connecting a profile to a post, or connecting a panel to a profile can be relatively simple and straightforward, A single person, in particular a single layman person, can in fact assembly the partition wall system on his own, without tools or instruments and without the need for assistance from other persons. Many variants and configurations are possible.

[0062] In another aspect, a partition wall system is provided comprising at least two vertical posts that can be erected uprightly and on each post a support element can be provided. A panel can be mounted to adjacent vertical posts supporting on the respective support elements. The support elements can be adjusted with respect to the posts, e.g. via a plug-in-hole connection, to ensure that the support elements in adjacent posts are at approximately the same height to receive the panel in an approximately horizontal way. Here, the panel may be provided with side edges comprising an engagement element for engagement to the corresponding vertical post. The engagement elements are, similar to the above described, preferably magnetic elements. The vertical post preferably has a hollow cross-section, more preferably a hollow cross-shaped cross-section. As such, a side edge of the panel can engage to an arm of the cross-shaped post. The support element may, relatively simple, be a pen mounted through a through bore of the post, or, in case of a hollow post, through aligned openings in opposite sides of the post. Other variants of a support element, e.g. a click-finger or a hook may be possible as well. In a further example, the support element may be a horizontal profile as described above.
