Definitions

  • the present invention relates to a system for creating a wall within a building.
  • Conventional residential building design comprises generally forming external and internal walls constructed in fixed positions relative to a floor slab.
  • the walls may comprise brick and mortar or frame walls but these walls are fixed in place during construction of the building.
  • the occupants of most buildings however often have changing needs over time. For example, as families grow, additional bedrooms may be required. Eventually as the children become adults and move out, less bedrooms may be required and the space may be better used for other activities. It would therefore be advantageous to utilise a construction in which the internal walls may be fixed in place to form rooms suitable for present needs but where the walls may be later moved to reconstruct the layout of rooms.
  • the present invention relates to a wall system which may be used to address the above issue.
  • the wall system is aimed at being simple to construct in the desired location and easily disassembled for moving if required.
  • a wall system comprising: a wall panel having a channel in a vertical edge thereof; an elongate latch member received into the channel; and one or more spring members located between the latch member and the channel to bias the latch member to move such that an outer edge of the latch member extends outwardly from an opening in the channel to be received into a corresponding channel in an adjacent panel or connecting member, the spring members being compressible to allow the latch member to retract inwardly into the channel for connection of the wall panel to the adjacent panel or connecting member; wherein the spring members each comprise a resilient arm member extending from the latch member and an inner wall of the channel includes one or more apertures located such that sliding the latch member downwardly causes distal ends of the arm members to pass through the aperture to be located behind the inner wall to retract the latch member into the channel for disconnection of the wall panel from the adjacent panel or connecting member.
  • the arm members are curved members extending downwardly from the inner side of the latch member at intervals along the length thereof.
  • the arm members each include a concave lower surface such that when the arm members have moved into the apertures, the lower concave surfaces of the arm members engage with the lower edges of the apertures so that the latch member hangs from the arm members.
  • the latch member includes a rib extending along an outer side thereof and the channel includes a narrowed neck portion such that the spring members bias the latch member to move so that the rib protrudes outwardly through the narrowed neck portion.
  • the wall panel includes first and second side members extending along opposed vertical edges thereof and first and second side sheets connected between the first and second side members.
  • the side members include the channel and a plurality of sheet supports extending outwardly from the channel to which the first and second side sheets are secured.
  • first and second end wall are provided extending outwardly from opposed sides of the opening in the channel such that the first end wall aligns with a first wall of a further wall panel or connecting member and the second end wall aligns with a second end wall of the further wall panel or connecting member.
  • a plurality of magnets are provided along the first and second end walls to engage with corresponding magnets or metal plates provided on the further wall panel or connecting member.
  • the magnets are provided in slots provided along the first and second end walls.
  • the sheet supports include a first flange extending perpendicular to a distal end of the first end wall and a second flange extending perpendicular to a distal end of the second end wall such that the first and second side sheets may be secured to outer surfaces of the first and second flanges.
  • first and second lips are provided extending out beyond the first and second flanges respectively, being coplanar with the first and second end walls to engage ends of the first and second side sheets respectively.
  • the side members are provided with further sheet supports extending outwardly from the channel adjacent the inner wall.
  • the further sheet supports comprise first and second arms, each of the arms includes a distal portion coplanar to the adjacent flange and a proximal portion extending from the distal portion at an angle thereto to the adjacent end of the inner wall of the channel such that outer surfaces of the distal portions are connectable to the sheets.
  • first and second side members each include a leg bracket for supporting a leg, the leg bracket being attachable to the further sheet supports.
  • skins are secured to outer surfaces of the side sheets using a plurality of metallic strips within the skins to engage with magnets provided on the side sheets.
  • skirtings are provided on each panel and are connectable to skirtings of adjacent panels by pins engaged into the holes in ends of the skirtings.
  • the skirtings each include a connector on an inner surface adjacent a lower edge including first and second slots in a lower side thereof to receive an upper edge portion of the lower track such that the first and second slots can be used to adjust the position of the skirting depending on whether the skin is attached to the side sheet.
  • the connecting members include slots extending inwardly at each corner to receive a corner protector strip.
  • the connecting members are provided with faceplate strips extending across faces of the connecting member to which panels are not connected.
  • a compressible end member is provided to engage between a panel and an adjacent wall.
  • the compressible end member comprises a base to engage with the wall, a protruding portion extending outwardly from the base to be received into the channel of the side member of the adjacent panel and a compressible block provided on each side of the protruding portion.
  • the compressible blocks each comprise a block of compressible material and a surface layer of an accordion shaped material to allow compression expansion.
  • first and second side members are shorter than the first and second side sheets and ducting is provided in the space between the sheets and above the side.
  • a light unit comprising a base plate onto which a housing is secured such that the base plate includes holes on opposed ends thereof to receive pins to connect the base plate to adjacent cornice pieces.
  • a wall system comprising: a wall panel having a channel in a vertical edge thereof; an elongate latch member received into the channel extendable outwardly from an opening in the channel to be received into a corresponding channel in an adjacent panel or connecting member wherein the latch member includes teeth thereon engaged by a cog such that rotation of the cog moves the latch member between extended and retracted positions.
  • the teeth are provided on a lower edge of the latch member and the cog is provided in an actuator unit located adjacent a lower end of the panel.
  • a wheel extends downwardly from the actuator unit such that turning the wheel by hand moves the latch member.
  • the actuator unit comprises a housing having a rotatably mounted drive shaft on which the cog is provided and the wheel rotates a first gear which engages with and rotates a second gear mounted onto the drive shaft.

Description

“Wall System”
Field of the Invention
[001 ] The present invention relates to a system for creating a wall within a building.
Background to the Invention
[002] Conventional residential building design comprises generally forming external and internal walls constructed in fixed positions relative to a floor slab. The walls may comprise brick and mortar or frame walls but these walls are fixed in place during construction of the building. The occupants of most buildings however often have changing needs over time. For example, as families grow, additional bedrooms may be required. Eventually as the children become adults and move out, less bedrooms may be required and the space may be better used for other activities. It would therefore be advantageous to utilise a construction in which the internal walls may be fixed in place to form rooms suitable for present needs but where the walls may be later moved to reconstruct the layout of rooms.
[003] The present invention relates to a wall system which may be used to address the above issue. The wall system is aimed at being simple to construct in the desired location and easily disassembled for moving if required.

Detailed Description of Preferred Embodiments
[110] Referring to the Figures, there is shown a wall system 10 comprising one or more wall panels 12. The wall panels 12 may be positioned adjacent further panels 12 and connected in place to form a wall structure. One or more connecting members 14 may be placed between adjacent wall panels 12 to either allow connection of two or more wall panels 12 at joins or comers.
[111 ] Each of the wall panels 12 comprises in the embodiment shown first and second side members 16 and 17 located along vertical edges of the wall panel 12. First and second side sheets 20 and 21 extend between the first and second side members 16 and 17 to define the wall panel 12 which may be used to form a wall structure comprising one or more of the wall panels 12. An insulating filler material (not shown) may be provided between the first and second side sheets 20 and 21 in use.

The channel 22 comprises first and second side walls 24 and 25 and an inner wall 26 extending between ends of the first and second side walls 24 and 25. The first and second side walls 24 and 25 are oriented generally parallel to the first and second side sheets 20 and 21 such that an opening 30 is defined between the first and second side walls 24 and 25 facing outwardly away from the vertical edge of the wall panel 12. The sheet supports extend outwardly from the channel 22 to allow attachment of the side sheets 20 and 21 to the first and second side members and 16 and 17.
[113] The side members 16 and 17 include first and second end walls 28 and 29 extending outwardly from opposite sides of the channel 22. The first end wall 28 extends outwardly from a distal end of the first side wall 24 generally perpendicular to the first side wall 24 and the second end wall 29 extends outwardly from a distal end of the second side wall 25 generally perpendicular to the second side wall 25. The first and second end walls 28 and 29 thereby define a vertical edge surface of the wall panel 12. The opening 30 is defined between the first and second end walls 28 and 29 extending along the length of the vertical edge surface of the wall panel 12.
[114] The sheet supports include a first flange 32 extending perpendicular to a distal end of the first end wall 28 and a second flange 33 extending perpendicular to a distal end of the second end wall 29. The first and second flanges 32 and 33 define outer surfaces parallel to the first and second side walls 24 and 25 of the channel 22 to which the first and second sheets 20 and 21 may be secured by suitable means, such as an adhesive. A first lip 34 is provided extending out beyond the first flange 32 coplanar with the first end wall 28 to engage an end of the first side sheet 20 and a second lip 35 extends out beyond the second flange 33 coplanar with the second end wall 29 to engage an end of the second side sheet 21 .
[115] The side members 16 and 17 are also provided with further sheet supports extending outwardly from the channel 22 adjacent the inner wall 26. The further sheet supports comprise first and second arm portions 36 and 37. Each of the arm portions 36 and 37 includes a distal portion 38 being coplanar to the adjacent flange 32 or 33 and a proximal portion 39 extending from the distal portion 38 at an angle thereto to the adjacent end of the inner wall 26 of the channel 22. Outer surfaces of the distal portions 38 of the first and second arms 36 and 37 are connectable to the sheets 20 and 21 by suitable means, such as an adhesive. Outer surfaces of the distal portions 38 of the arms 36 and 37 and outer surfaces of the flanges 32 and 33 may have a plurality of grooves therein to receive adhesive and better support the sheets 20 and 21 .
[116] Each of the first and second side members 24 and 25 includes a leg bracket 40 for supporting a leg 42 on which the wall panel 12 may rest in use. The leg 42 comprises a threaded shaft 44 having a foot 46 on the lower end thereof. The leg bracket 40 comprises a cylinder 48 having an internal thread to receive the threaded shaft 44. The cylinder 48 includes a pair of struts 50 extending outwardly therefrom such that the struts 50 may be engaged with the proximal portions 39 of the first and second arms 36 and 37 to connect to the leg support 42 to the adjacent side member 16 or 17 adjacent a lower end thereof. When connected to the side member 16 or 17, the shaft 42 of the leg extends downwardly below lower edges of the wall panel 12 such that the wall panel 12 may rest on the foot 46 and the height of the wall panel 12 may be adjusted by rotating the leg 42 relative to the cylinder 48. In the embodiment shown, each of the struts 50 includes a transverse end portion which may be slid into a corresponding bracket 54 formed on the proximal portion 39 of the arm 36 and 37 to engage the leg support 40 with the end member 16 or 17.
[117] The vertical edge of each wall panel 12 is connectable to either a vertical edge of an adjacent wall panel 12 or a side of a connecting member 14. The connecting members 14 may be provided to allow connection of adjacent wall panels 12 in multiple configurations. Figures 14 to 16 show examples where connected members are provided to allow connection of wall panels 12 in a variety of configurations. It will be appreciated however that connecting members 14 of other configurations may also be used to connect alternate numbers of wall panels 12 together, or at other angles.
[118] When connecting an adjacent pair of wall panels 12, the first end wall 28 of one of the wall panels 12 aligns with the first end wall 28 of the adjacent wall panel 12 and the second end wall 29 of the first wall panel 12 aligns with the second end wall 29 of the adjacent wall panel 12. Each of the first and second end walls 28 and 29 is provided with a plurality of magnets 56 provided at intervals along the length thereof. In the embodiment shown, the first and second end walls 28 and 29 include grooves 58 along the length thereof and the magnets 56 comprise planar rectangular magnets 56 which are slid into the slots 58 such that the magnets 56 align with magnets or metal plates on the adjacent wall panel 12 to generally hold adjacent wall panels 12 together.
[119] A first vertical edge of the wall panel 12 is provided with a latch member 60 in the channel 22. The latch member 60 is provided to engage into the opening 30 of the adjacent wall panel 12 such that when the outer end of the latch member 60 engages into the opening 30, the adjacent wall panels 12 align to form part of the wall structure.
[120] The latch 60 comprises an elongate member which may be slid into the channel 22 from an end thereof. The channel 22 includes a narrowed neck portion 62 at the opening 30 such that the latch member 60 may be received within the channel 22 by sliding into one of the ends of the channel 22. The latch member 60 includes a rib 64 along the length thereof such that the rib 64 may protrude outwardly through the opening 30 to be received within the opening 30 in the channel 22 of the adjacent wall panel 12. One or more spring members 66 are provided on a side of the latch member 62 opposite the rib 64 such that the spring members 66 engage with the inner wall 62 of the channel 22 to bias the latch member 60 to move towards the opening 30. The spring members 66 thereby move the latch member 60 such that the rib 64 protrudes outwardly through the opening 30.
[121 ] The latch member 60 may be moved inwardly into the channel 22 by a force applied inward onto the rib 64, thereby compressing the spring members 66. Adjacent wall panels 12 may therefore be attached by generally aligning the vertical edges and pushing the wall panels 12 together such that the openings 30 are aligned and the rib 64 is urged by the spring members 66 into the opening 30 (as can be seen for example in Figure 9b) to connect the wall panels 12.
[122] In the embodiment shown, each of the spring members 66 comprises an arm member 68 extending outwardly from an inner surface of the latch member 60 (as best seen in Figures 10 to 13). The arm members 68 have proximal ends secured to the latch member 60 and extend downwardly such that distal ends of the arm members 68 are located below proximal ends thereof. The arm members 68 are each curved such that the arm members 68 include a concave lower surface. An outer end of each of the arm members 68 engages with an inner surface of the inner wall 26 of the channel 22 such that when the latch member 60 is pushed towards the inner wall 26, the arm member 68 is compressed to bias the latch member 60 to move outwardly.
[123] The inner wall 26 includes a plurality of apertures 70 along the length thereof. The apertures 70 are located at intervals corresponding to the intervals between the arm members 68. Sliding the latch member 60 along the channel 22 therefore results in moving the arm members 68 between positions where they are in alignment of the apertures 70 and positions where they are out of alignment with the apertures 70.
[124] Sliding the latch member 60 to the position where the arm members 68 are aligned with the apertures 70 causes distal ends of the arm members 68 to move through the apertures 70 to a location behind the inner wall 26 (as can be seen in Figures 12 and 13). This thereby disengages the biasing force on the latch member 60 and allows the latch member 60 to move towards the inner wall 26. This movement retracts the rib 64 from the channel 22 of the adjacent wall panel 12 and allows adjacent wall panels 12 to be disconnected. When the arm members 68 have moved into the apertures, the lower concave surfaces of the arm members 68 engage with the lower edges of the apertures 70 so that the latch member 60 hangs from the arm members 68.
[125] Each of the connecting members 14 includes a plurality of sides into which a vertical edge of an adjacent wall panel 12 may be connected. In the embodiment shown in Figure 9a, the connecting member 14 includes a generally rectangular extrusion having four sides each capable of connecting to a wall panel 12. Each side of the connecting member 14 includes a first end wall portion 78 and a second end wall portion 79 located either side of a central groove 80. Each of the first and second end wall portions 78 and 79 are provided to engage with a corresponding first and second end wall 28 and 29 of the adjacent wall panel 12 and the groove 80 is provided to receive the rib 64 of the latch member 60 of the adjacent wall panel 12. The connecting member 14 may be provided with a leg support 40 adjacent a lower end thereof for attaching an adjustable leg 42.
[126] Each of the wall panels 12 is also provided with upper and lower cover plate 72 and 74 provided to extend between upper and lower ends of the first and second side sheets 20 and 21 respectively to enclose upper and lower ends of the wall panel 12. The upper and lower cover plates 72 and 74 include openings to allow for wiring to pass into the wall panel 12. The openings may be formed by perforated sections of the upper and lower cover plates 72 and 74 which can be removed.
[127] The wall panel 12 may include skirtings 82 provided to extend between a lower edge of the wall panel 12 and the floor. The skirtings 82 are connectable to skirting brackets 84 which engage with the shaft 44 of the leg 42, as can be seen in Figure 7b. The wall panel 12 may also be provided with cornice pieces 86 to extend between upper edges of the wall panel 12 and the ceiling, as can be seen in Figure 7a. The skirtings 82 and cornice pieces 86 may be connectable by snap fit type connection, or by magnetic connectors.
[128] The wall panel 10 may further be provided with skin panels 90 which are connectable to the outer surfaces of the first and second side sheets 20 and 21 . The skin panels are provided in a range of appearances such that the skin panels may be removed and replaced in order to alter the appearance of the wall structure.
[129] Figures 17 to 42 a further embodiment of wall system 10 in accordance with the present invention. In this embodiment, the first and second side members 16 and 17 are formed in an alternate shape. As can be seen in Figure 18f, the arms 36 and 37 are no longer angled away from the channel 22 but are L-shaped such that the arms 36 and 37 extend parallel away from the first and second side walls 24 and 25 of the channel 22 and then transversely outwardly to the distal portions 38. Also, the first and second flanges 32 and 33 extend backwardly to connect with the distal portions 38. That is, the side members 16 and 17 include outer walls 92 on either side of the channel 24 to which the side sheets 20 and 21 are connected.
[130] As can be seen in Figure 17, this version includes skins 90 secured to outer surfaces of the side sheets 20 and 21 . The skins 90 includes a plurality of metallic strips 94 which are engaged by magnets 96 provided on the side sheets 20 and 21 to secure the skins 90 in place.
[131 ] The skirtings 82 in the embodiment of Figures 17 to 40 of each panel 12 are connectable to skirtings 82 of adjacent panels. As can be seen in Figure 20, ends of the skirtings 82 include a plurality of holes 100 to receive pins 98. The pins 98 engage into the holes 100 of an adjacent pair of skirtings 82 to connect to the skirtings 82 together.
[132] The panels 12 may also be provided with a lower track 124 on which the feet 46 rest in use. As can be seen in Figure 18e, a lower surface of the feet 46 include slots 126 to receive the ribs provided on an upper surface of the track 124 to locate the feet 46.
[133] The skirtings 82 each include a connector 160 on an inner surface adjacent a lower edge (as can be seen in Figure 18e). The connectors 160 include first and second slots in a lower side thereof to receive an upper edge portion of the lower track 124. The first and second slots can be used to adjust the position of the skirting 82 depending on whether the skin 90 is attached to the side sheet 20 or 21 . If no skin 90 is used, an innermost of the slots receives the side edge portion of the lower track 124 and if the skin 90 is used (as shown in figure 18e) then the side edge of the lower track 124 is received in the outermost of the slots in the connector 160.
[134] An upper edge of the skirtings 82 also include a plurality of magnets to engage the upper edge of the skirting 82 with the outer surface of the skin 90 or the sheet 20 or 21 .
[135] Figures 22 to 25 show an alternative mechanism for moving the latch member 60 between the retracted and extended positions. In this embodiment, the latch member 60 is engaged by an actuator unit 102 located adjacent a lower end of the latch member 60. The actuator unit 102 comprises a housing 104 having a rotatably mounted drive shaft 106. The drive shaft 106 may be turned by a wheel 108 which may be rotated by hand.
[136] In the embodiment shown, the wheel 108 extends out below a lower end of the housing 104 and may be turned by hand to rotate a first gear 110 which engages with and rotates a second gear 111 mounted onto the drive shaft 106. A cog 112 is mounted on the drive shaft 106 to engage with teeth on a lower side of the latch member 60 such that rotation of the wheel 108 causes the latch member 60 to move inwardly or outwardly relative to the channel 24. The latch 60 may therefore be easily extended or retracted by gripping and rotating the wheel 108.
[137] Figures 26 to 28 show another version of a connecting member 14. The connecting member 14 comprises a rectangular post having a slot 114 extending inwardly at each corner. Each of the slots 114 in the embodiment shown are angled at around 45° to each of the adjacent faces of the connecting member 14. Each of the slots 114 is provided to receive a corner protector strip 116 which may be used to cover comers of the connecting member 14 when connected to an adjacent panel 12. As can be seen in Figure 27, each of the corner protector strips 116 includes an elongate planar portion received into one of the slots 114 and an L-shaped corner portion 120 to extend around exposed corner of the post.
[138] The rectangular connecting members 14 may also be provided with faceplate strips 122 extending across faces of the connecting member 14 to which panels 12 are not connected. The faceplate strips 122 are held in place by magnets.
[139] The wall system 10 may also include a compressible end member 128 as can be seen in Figure 29. The compressible end member 128 includes a base 130 to engage with a wall adjacent an end of a panel 12. The base 130 includes a protruding portion 132 which extends outwardly from the base 130 to be received into the channel 24 of the side member of the adjacent panel 12. [140] Either side of the protruding portion 132 is provided with a compressible block 134. In the embodiment shown, the compressible blocks 134 each comprise a block of suitable material, such as a foam material, secured to the base 130 and an adjacent side of the protruding portion 132. An outer surface of the compressible block 134 includes a surface layer 136 of an accordion shaped material to allow compression expansion. As can be seen in Figure 29 the protruding portion 132 of the compressible end member 128 may slide in and out of the channel 24 and the compressible block 134 may expand or contract to fill the space between the end of the panel 12 and the wall to provide a neat finish.
[141 ] As can be seen in Figures 30 and 31 , the wall system may be provided with alternate shaped connecting members 14. In Figure 30 a connecting member 14 is provided having a curve instead of a right angle corner. A corresponding curved skirting portion 138 is provided to extend around the curved side of the connecting member 14.
[142] Figures 32 to 35 show a further alternative configuration where ducting is provided within each of the panels 12. The ducting may be used to run electrical cable or other services through the constructed wall.
[143] As can be seen, the first and second side members 16 and 17 are shorter than the first and second side sheets 20 and 21 . The space between the sheets 20 and 21 and above the side members 16 and 17 is thereby used to provide the ducting. Each of the panels 12 is provided with first and second tubular members 140 and 141 to be engaged on top of the first and second side members 16 and 17 respectively. A flexible duct portion 142 is connected between the first and second tubular members 140 and 141 .
[144] Each of the connecting members 14 is also shorter than the height of the sheets 20 and 21 and provided with a tubular connecting member 144 through which cable may pass.
[145] As shown in Figure 35, each of the duct portions 142 preferably includes a rigid connection ring 146 at each end thereof. The connection rings 146 are provided to connect to connection rings 146 of adjacent duct portions 142 or to the tubular members 140 and 141 provided above the side members 16 and 17 of the panels 12. The connection rings 146 may include male/female connections thereon to engage with each other or may include a series of magnets to make connection.
[146] Figures 37 and 38 show a light unit 148 which may be attached to one of the panels 12. The light unit 148 comprises a base plate 152 onto which a housing 150 is secured. The housing 150 includes a light 154 provided to emit light outwardly through a transparent panel 156 provided adjacent an upper end of the housing 150. The base plate 152 includes holes 100 on opposed ends thereof to receive pins 98 of the type used to secure together the skirtings 82.
[147] The light unit 148 is thereby secured between an adjacent pair of cornice pieces 86 by pins 98 as can be seen. The base plate 152 includes an upper flange 158 to extend out above the upper edge of the panel 12 to further secure the light unit 148.
[148] Figures 39 and 40 show an alternative version of the skirtings 82. As can be seen, a lower edge of the skin 90 includes a recessed portion 162 on an inner surface thereof and an upper edge of the skirting 82 is received in the recessed portion 162. The connector 160 on the skirting 82 engages with the side edge portion of the lower track 124 as described previously and this arrangement defines a skirting 182 which is recessed inwardly from the outer surface of the panel 12.
[149] It will be readily apparent to persons skilled in the relevant arts that various modifications and improvements may be made to the foregoing embodiments, in addition to those already described, without departing from the basic inventive concepts of the present invention.
