The following table lists particular features of the furniture module, in the form of a wardrobe, and their respective reference numeral as described in the text below and in the figures.

As the wardrobe is intended to stand on the floor in a room with a ceiling / roof, certain features of the wardrobe are described using the terms lower and upper which are relative to the bottom (or room floor) and top (or room ceiling) ends of the wardrobe. Lower is intended to imply to any position that is below or further away from the top end of the wardrobe (or room ceiling) in the direction of the wardrobe bottom (or room floor). Conversely, upper is intended to imply to a position that is above or further away from the bottom end of the wardrobe (or room floor) in the direction of the wardrobe top (or room ceiling). Vertical and horizontal wardrobe features have orientations that are approximately perpendicular and parallel respectively to the bottom (or room floor) and top (or room ceiling) ends of the wardrobe.

Figs. 1 to 9B illustrate the assembly of a wardrobe 170. The main components of the wardrobe 170 are a housing 100 comprising a back piece 102 and two side walls 106, a ceiling 140, and a floor 160. The back piece 102 is preferably pre-mounted to the side walls 106 for easier assembling of the wardrobe 170.

Fig. 1 depicts a user commencing assembly of the wardrobe 170 by moving a housing 100 into a suitable position. The housing 100 in Fig. 1 has a folded-up conformation which allows smaller packaging and more efficient transport of the unassembled wardrobe 170.

As shown in Fig. 2, housing 100 has a back piece 102 and two side walls 106 pre-mounted to side edges of the back piece 102. The back piece 102 is preferably foldable and has a centre line 104 about which the back piece 102 is foldable to facilitate compact packaging and transport of the unassembled wardrobe. Each side wall 106 has a plurality of pre-drilled holes 108 for receiving fastening elements (not shown) such as screws that may be utilized in the installation of shelves, brackets, or apparel- hanging rods in the wardrobe, if desired. Back piece 102 is a thin board of sheet-type material whereas the side walls 106 are thicker than the back piece. The housing 100 is in a partially unfolded conformation in Fig. 2. During assembly housing 102 is fully unfolded by moving each side wall 106 further away from each other in the directions of the block arrows in Fig. 2 to the conformation in Fig. 3A. When unfolding the housing the edges of the back piece 102 are already fixedly attached to grooves 1 10 on the side walls 106 as best seen at the top of Fig. 2. Glue or another suitable adhesive is preferably applied to the edges of the back piece 102 and / or grooves 110 during manufacturing, such that the back piece 102 is premounted the side walls 106 when the wardrobe 170 is to be assembled. As the back piece 102 is fixed to the side walls 106 strength and stability is added to the wardrobe during assembly.

The back piece 102 is preferably produced by a board being covered by a surface layer 103, or foil. The ability to fold the back piece 102 is preferably achieved by providing a slit through the board, while leaving the surface layer 103 intact. The surface layer or foil 103 will thus ensure that the back piece 102 is foldable. As is further shown in Fig. 2 the back piece 102 has small slits 105 adjacent to its edges, whereby the slits 105 are positioned such that they allow the back piece 102 to fold and unfold, respectively. The slits 105 thus act as hinges for the back piece 102 to allow it to be positioned in parallel with the side walls 106 (before assembly) and perpendicular to the side walls 106 (when assembled), and of course any position there between. As explained above, folding is possible due to the flexibility of the surface layer 103.

Fig. 3 A shows four wardrobe floor supporters 112 engaging with the lower portion of the side walls 106. Each floor supporter 112 has an approximately rectangular prismatic shape. Once installed on the side wall 106 the rectangular faces of supporter 112 are vertical. A recess 113 is located on one vertical face of the prism. A support pin 114 is located on the upper horizontal face of the supporter 112. The recess 113 and the pin 114 are described further below. Beam receiving holes 119, 120 as shown in Fig. 3 A will also be described below in respect of Figs. 5 A, 5B, and 5C. Each supporter 112 also has two securing projections 115, 116 located on another vertical face of supporter 112 opposing the recess 113. The securing projections 115, 116 are receivable by holes 117, 118 on each side wall 106. Securing of a supporter 112 onto a side wall 106 is illustrated in more detail in Figs. 3B, 3C, 4A, and 4B. Projection 116 is inserted horizontally into hole 118 while projection 115 is inserted into the larger portion of hole 117 so that the vertical axis of the supporter 112 is tilted relative to the vertical axis of the housing 100 as seen in Fig. 4A. Force is then applied to supporter 112 in the direction of the straight block arrow in Fig. 3B and the straight arrow in Fig. 4 A to secure the projection 116 into hole 118. At the same time a tilting force is applied to the supporter 112 in the direction of the curved arrows in Figs. 3B and 4A to secure projection 115 into the smaller portion of hole 117. Figs. 3C and 4B show the wardrobe floor supporter 112 in complete engagement with side wall 106.

Fig. 5 A shows a front beam 122 engaging with the lower portion of the side walls 106 of unfolded and assembled housing 100. Front beam 122 is rectangular prismatic in shape and has beam securing projections 124 and 125 on both vertical end faces of the beam 122. Each projection 124 and 125 is threaded to correspond with a threaded portion of holes 119 and 120. Installation of the front beam 122 to the front of the wardrobe is shown in Figs. 5B and 5C. Threaded projection 124 is inserted horizontally into the unthreaded portion of hole 120 on side wall 106 at the same time threaded projection 125 is inserted horizontally into the unthreaded portion of hole 119 in the direction of the block arrows in Fig. 5B. This is repeated at the opposing end of the beam 122 (not shown). Force is then applied to beam 122 in the direction of the block arrows in Fig. 5C to lower and secure the projections 124, 125 into the threaded portions of holes 119 and 120. Once installed front beam 122 provides additional strength to the wardrobe and covers the gap between wardrobe floor and room floor.

A back beam 130 is installed at the rear and lower portion of the wardrobe as depicted in Fig. 6A. The back beam 130 is also rectangular prismatic in shape and has two fasteners 132 on a longitudinal rectangular face of the back beam 130. Installation of the back beam 130 is shown in Figs. 6A, 6B, 6C, and 6D. An end portion of beam 130 is lowered into the recess 113 of a floor supporter 112 as shown by the block arrows in Fig 6A until the position of fastener 132 corresponds with an aperture in back piece 102 as shown in Fig. 6B. The beam 130 and the back piece 102 are then squeezed together as shown in Fig. 6C resulting in fastener head 134 on fastener 132 passing through the aperture on the back piece 102. The beam 130 is then further lowered into recess 113 so that the back piece 102 is located in between the back beam 130 and the fastener head 134 as shown in Fig. 6D.

Figs. 7, 7A, 7B, 7C, and 7D illustrate fitting of a wardrobe ceiling 140 to the upper portion of the side walls 106. Ceiling 140 has securing projections 141, 142, and 143 on two opposing ends of the ceiling 140. Ceiling 140 is lowered at an inclined angle relative to the side wall 106 and back piece 12 in order that projection 143 is lowered vertically into wall recess 146 as shown by the block arrows in Figs. 7A, 7B. Ceiling

140 is then moved horizontally towards the back piece 102 as shown by the block arrow in Fig. 7C to secure projection 143 further into wall recess 146. This also lines up projection 142 in close proximity with wall recess 145. Finally ceiling 140 is lowered into a horizontal position in which projections 141 and 142 are inserted into wall recesses 144 and 145 respectively as shown by the block arrows in Fig. 7D. A groove on the lower face of ceiling 140 receives the upper edge of back piece 102.

A cap 148 is placed over securing projections 141, 142, and 143 as shown in Fig. 8 after installation of the ceiling 140 on the wardrobe. The cap 148 has a wedge 152 that is slid securely into cut-out 150 on side wall 106. Cap 148 ensures the securing projections 141, 142, and 143 are not accidentally removed from the wall recesses 144, 145, and 146 and provides the ceiling with a more visually pleasing appearance.

Fig. 9 A illustrates fitting of wardrobe floor 160 into the wardrobe. The wardrobe floor 160 has four wardrobe floor recesses 162 located near the corners of the floor 160. The floor 160 is lowered into the wardrobe until each floor recess 162 receives the pin 114 of floor supporter 112. The floor supporter 112 also has a foot 172 that is in contact with the floor of the room where the wardrobe is standing. In an alternative embodiment (not illustrated) the foot 172 is an adjustable foot and the pin 114 is a rotatable pin that is operatively connected to the adjustable foot. Rotation of the pin in a clockwise or anticlockwise direction results in vertical up or down movement of the adjustable foot. This is most useful where the wardrobe is to stand on a floor that is not level. One or more of the adjustable feet on the floor supporter 112 can be lowered until the foot / feet contacts the floor of the room simply by rotating the pin prior to installation of the wardrobe floor 160.

In another embodiment (also not illustrated) one or more brackets may be mounted with screws or other fasteners to the uppermost portion of the interior face of the side wall 106 and / or the back piece 102 to further support the ceiling 140 of the wardrobe. Such brackets may be mounted using pre-drilled holes 108 or new holes may be drilled into the side walls and / or back piece. The brackets may be corner brackets that are mounted to both a side wall and the back piece in the uppermost interior corners of the wardrobe.

The assembled wardrobe 170 is shown in Fig. 9B. Advantageously, the wardrobe 170 is able to be assembled in less than five minutes by a single person. The structure and design of the wardrobe's component parts for example, the foldable back piece 102, allows the wardrobe to be transported in a convenient flat package.

Figs. 10-16 show different embodiments of a housing 200, 300, 400, 500, 600,

700, 800 and more specifically different ways of how the back piece can be pre- mounted to the side walls. Other features of the housing may be similar to what has been described above.

Figs. 10A, IOC, and 10E show the folding sequence for erecting the sidewalls 206 relative the back piece 202. Fig. 10B is a detailed view of a corner of the housing 200 shown in Fig. 10A. Fig. 10D is a detailed view of a corner between the back piece 202 and a side wall 206 of the housing 200 shown in Fig. IOC and Fig. 1 OF is a detailed view of the corner shown in Fig. 10E. In the shown embodiment the back piece 202 is foldable and has a centre line 204 about which the back piece 202 is foldable to facilitate compact packaging and transport of the unassembled wardrobe. A first surface layer 203 of the back piece 202, which when in an unfolded state (see Fig. 10A) faces a side wall 106, is at least partly provided with a layer 280, for example a flexible and/or resilient layer used for attaching the sidewall 206 to the back piece 202. The layer 280 may e.g. be in the form of a foil. The back piece 202 is pre-mounted, by means of the layer 280, to an inner surface 207 of each side wall 206 slightly remote from the rear edge 209 of the side wall 206. The layer 280 extends from the first surface layer 203 to the inner surface 207 of each side wall 206, preferably towards the rear edge 209 of the side wall 206. Thus, the back piece 202 is pre-mounted to the side walls 206 by means of the layer 280. The layer 280, which may be formed by an adhesive, allows the back piece 202 to move between the unfolded state, shown in Fig, 10A, and the folded state, shown in Fig, 10E. Hence, the layer 280 will have a function similar to that of a hinge, making it possible for the back piece 202 to be turned relative to the side wall 206. The layer 280 may be an adhesive and may comprise a glue, preferably a melt glue, such as a reactive type of melt glue or a thermoplastic type of melt glue.

According to another embodiment Figs. 1 1A, 11 C, and 1 IE show the folding sequence for erecting the sidewalls 306 relative the back piece 302. Fig. 1 IB is a detailed view of a corner of the housing 300 shown in Fig. 1 1 A. Fig. 1 ID is a detailed view of a comer between the back piece 302 and a side wall 306 of the housing 300 shown in Fig. 1 1 C and Fig. 1 IF is a detailed view of the corner shown in Fig. 1 IE. In this embodiment the back piece 302 is again foldable about a centre line 304. A first surface layer 303 of the back piece 302, which when in an unfolded state (see Fig. 11 A) faces a side wall 306, is at least partly provided with a layer 380. The layer 380 is preferably resilient, such as in the form of a foil, and used for attaching the sidewall 306 to the back piece 302. The back piece 302 is pre-mounted, by means of the layer 380, to a rear edge 309 of each side wall 306. The layer 380 extends from the first surface layer 303 to the rear edge 309 and preferably along a portion of the rear surface 306' of each side wall 306. As can be seen in Figs 1 IB, D and F the rear surface 306' the side wall 306 is at least partly inclined. The inclination angle substantially corresponds to the thickness of the back piece 302 such that the rear surface 302' of the back piece 302 in its unfolded state is flush with the most rear portion 306" of the side wall 306. The layer 380 allows the back piece 302 to move between the unfolded state and the folded state, which corresponds to a fold of approximately 90 degrees.

According to another embodiment Figs. 12A, 12C, and 12E show the folding sequence for erecting the sidewalls 406 relative the back piece 402. Fig. 12B is a detailed view of a corner of the housing 400 shown in Fig. 12A. Fig. 12D is a detailed view of a comer between the back piece 402 and a side wall 406 of the housing 400 shown in Fig. 12C and Fig. 12F is a detailed view of the corner shown in Fig. 12E. In this another alternative embodiment the back piece 402 is not foldable along a centre line. Instead the side walls 406 are folded along the back piece 402 towards the centre of the back piece 402 for compact packaging and transportation of the unassembled wardrobe. When unfolding the housing 400 the side walls 406 are unfolded

approximately 90 degrees from the back piece 402. The back piece 402 and the side walls 406 are pre-mounted to each other by means of an adhesive 480, for example glue. The adhesive 480 is preferably provided along the entire height of the back piece 402 and/or side wall 406. When hardened, the glue forms a resilient attachment joint between the sidewall 406 and the back piece 402. A portion of the edge 406' of the side wall 406 has been cut off in order to create an area for attaching the back piece 402. The height of the cut off edge 406' corresponds to the thickness of the back piece 402 such that when the housing 400 is in its unfolded state, see Figs 12E and F, the rear surface 402' of the back piece 402 is flush with the most rear portion 406" of the side wall 406.

According to another embodiment Figs. 13 A, 13C, and 13E show the folding sequence for erecting the sidewalls 506 relative the back piece 502. Fig. 13B is a detailed view of a corner of the housing 500 shown in Fig. 13 A. Fig. 13D is a detailed view of a comer between the back piece 502 and a side wall 506 of the housing 500 shown in Fig. 13C and Fig. 13F is a detailed view of the corner shown in Fig. 13E. In this embodiment the back piece 502 is yet again foldable, having a centre line 504 about which the back piece 502 is foldable. Also in this embodiment the back piece 502 and the side walls 506 are pre-mounted to each other by means of an adhesive 580, for example glue. The adhesive 580 is preferably provided along the entire height of the back piece 502 and/or side wall 506 respectively. When hardened, the glue forms a resilient attachment joint between the sidewall 506 and the back piece 502. Yet again, a portion of the edge 506' of the side wall 506, has been cut off in order to create a desired area for attaching the back piece 502 with the adhesive 580. The height of the cut off edge 506' corresponds to the thickness of the back piece 502 such that when the housing 500 is in its unfolded state, see Figs 13E and F, the rear surface 502' of the back piece 502 is flush with the most rear portion 506" of the side wall 506. In addition, the edge of the back piece 502, which is attached to the side wall 506, has an inclined surface extending from the attachment point P to its rear surface 506' . The inclination of the surface preferably correspond to the inclination of the cut off edge 506' of the side wall 506.

According to another embodiment Figs. 14A, 14C, and 14E show the folding sequence for erecting the sidewalls 606 relative the back piece 602. Fig. 14B is a detailed view of a corner of the housing 600 shown in Fig. 14A. Fig. 14D is a detailed view of a comer between the back piece 602 and a side wall 606 of the housing 600 shown in Fig. 14C and Fig. 14F is a detailed view of the corner shown in Fig. 14E. In the shown embodiment the back piece 602 is foldable and has a centre line 604 about which the back piece 602 is foldable to facilitate compact packaging and transport of the unassembled wardrobe. Each side wall 606 is provided with a groove 610 which is displaced away from the rear edge 606' of the side wall 606. The groove 610 extends from an opening on the inner surface 607 of the side wall 606 towards its centre. In order to pre-mount the back piece 602 to the side wall 606 a portion 602a of the back piece 602 is inserted into the groove 610. Preferably, an adhesive 680 is also provided in the groove 610 to even more secure to the portion 602a of the back piece 602. The back piece 602 has a slit 605 located at the opening of the groove 610, in order to allow the back piece 602 to be folded towards the side wall 606. At the location of the slit 605 the back piece 602 may be reinforced, e.g. by means of a thin and flexible foil ensuring that the back piece 602 will remain as a single piece.

According to another embodiment Figs. 15 A, 15C, and 15E show the folding sequence for erecting the sidewalls 706 relative the back piece 702. Fig. 15B is a detailed view of a corner of the housing 700 shown in Fig. 15 A. Fig. 15D is a detailed view of a comer between the back piece 702 and a side wall 706 of the housing 700 shown in Fig. 15C and Fig. 15F is a detailed view of the corner shown in Fig. 15E. In the shown embodiment the back piece 702 is yet again foldable about a centre line 704. Each side wall 706 is provided with a groove 710 in this case being arranged on the rear edge 706" of the side wall 706. The groove 710 extends from the inner surface 707 of the side wall 706 towards its centre but differs from the previously described embodiment in that the groove 710 is open along the rear edge 706" of the side wall 706. In order to pre-mount the back piece 702 to the side wall 706 a portion 702a of the back piece 702 is placed in the groove 710. Preferably, an adhesive 780 is also provided in the groove 710 to even more secure to the portion 702a of the back piece 702. The back piece 702 has a slit 705 located at the opening of the groove 710, in order to allow the back piece 702 to be folded towards the side wall 706. The width of the groove 710 corresponds to the thickness of the back piece 702 such that when the housing 700 is in its unfolded state, see Figs 15E and F, the rear surface 702' of the back piece 702 is flush with the most rear portion 706" of the side wall 706.

According to another embodiment Figs. 16A, 16C, and 16E show the folding sequence for erecting the sidewalls 806 relative the back piece 802. Fig. 16B is a detailed view of a corner of the housing 800 shown in Fig. 16A.

In the shown embodiment the back piece 802 is again foldable about a centre line 804. Each side wall 806 is provided with a groove 810 in this case extending along the inside surface 807 of the side wall 806. The groove 810 extends preferably from the rear edge 806" of the side wall 806 down a length along it's inside surface 807. The groove 810 is open along the inside surface 807 of the side wall 806. In order to pre-mount the back piece 802 to the side wall 806 each end portion 802a of the back piece 802 is L-shaped, in an unfolded state, see Fig 16F. The base 802b of the L-shaped portion 802a is placed in the groove 810. In the break between the base 802b and the back 802c of the L- shaped portion there is provided a slit 805 such that the back 802c of the L-shaped portion 802a and the rest of the back piece 802 is able to be folded towards the side walls 806. The slit 805 is preferably perpendicular relative the back 802c of the L- shaped portion 802a but may also be arranged at 45 degrees or at any other desired angle. Preferably, there is provided an adhesive 880 in the groove 810 to secure the back piece 802. The width of the groove 810 may preferably correspond to the thickness of the back piece 802. The end portion 802a of the back piece 802 is L-shaped in the unfolded state of the housing 800 as can be seen in Figs 16E and F.

In addition, the furniture module has been described as having a "top" and "bottom" ends, and comprising "side" walls. A skilled person realizes that such a furniture module, when assembled, ca be arranged with the "side" walls facing the floor and ceiling, respectively, and the "top" and "bottom" ends thus being "left" and "right" ends. For instance, a TV bench, which is typical a low, in height, but wide fumiture module which may be provided using the present invention by having the back piece pre-mounted to the top and bottom fumiture panels. Such an embodiment is disclosed in Figs. 17A-F. Figs. 17A, 17C, and 17E show the folding sequence for erecting the furniture panels 906a-b relative the back piece 902. Fig. 17B is a detailed view of a rear end of the folded housing 900 shown in Fig. 17 A. Fig. 17D is a detailed view of a comer between the back piece 902 and a furniture panel 906a of the housing 900 shown in Fig. 17C and Fig. 17F is a detailed view of the corner shown in Fig. 17E. In this embodiment the back piece 902 is yet again foldable, having a centre line 904 about which the back piece 902 is foldable. Also in this embodiment the back piece 902 and the fumiture panels 506a-b are pre-mounted to each other by means of an adhesive 980, for example glue. The adhesive 980 is preferably provided along the entire height of the back piece 902 and/or furniture panels 906a-b respectively. When hardened, the glue forms a resilient attachment joint between each one of the furniture panels 906a-b and the back piece 902. Yet again, a portion of the edge 906' of each furniture panel 906a-b, has been cut off in order to create a desired area for attaching the back piece 902 with the adhesive 980. The height of the cut off edge 906' corresponds to the thickness of the back piece 902 such that when the housing 900 is in its unfolded state, see Figs 17E and F, the rear surface 902' of the back piece 902 is flush with the most rear portion 906" of the furniture panel 906a-b. In addition, the edge of the back piece 902, which is attached to the furniture panel 906, has an inclined surface extending from the attachment point P to its rear surface 902' . The inclination of the surface preferably correspond to the inclination of the cut off edge 906' of the furniture panel 906.

It is also realized that the furniture module according to the present invention could have one or several interior walls, being parallel with the side walls or furniture panels. Interior walls might be needed for instance for a wide wardrobe, e.g. a wardrobe having a larger width that e.g. 1 meter. Such and embodiment is shown in Figs. 18A-F.

Figs. 18 A, 18C, and 18E show the folding sequence for erecting the furniture panels 1006a-b forming the side walls, as well as the furniture panel 1006c forming the interior wall, relative the back pieces 1002a-b. Fig. 18B is a detailed view of a rear end of the folded housing 1000 shown in Fig. 18A. Fig. 18D is a detailed view of a corner between each one of the back pieces 1002a-b and the interior wall 1006c of the housing 1000 shown in Fig. 18C and Fig. 18F is a detailed view of the comer shown in Fig. 18E. In this embodiment each back piece 1002a-b is yet again foldable, having a centre line 1004a-b about which the respective back piece 1002a-b is foldable. Also in this embodiment each back piece 1002a-b is pre-mounted to furniture panels 1006a-c by means of an adhesive 1080, for example glue. The adhesive 1080 is preferably provided along the entire height of each back piece 1002a-b and/or furniture panels 1006a-c respectively. When hardened, the glue forms a resilient attachment joint between each one of the furniture panels 1006a-c, i.e. the side walls as well as the interior wall, and the back pieces 1002a-b. Yet again, a portion of the edge 1006' of each furniture panel 1006a-c, has been cut off in order to create a desired area for attaching a respective back piece 1002a-b with the adhesive 1080. The height of the cut off edge 1006' corresponds to the thickness of the back piece 1002a-b such that when the housing 1000 is in its unfolded state, see Figs 18E and F, the rear surface 1002' of each back piece 1002a-b is flush with the most rear portion 1006" of the furniture panel 1006a-c. In addition, the edge of each back piece 1002a-b, which is attached to the furniture panel 1006a-c, has an inclined surface extending from the attachment point P to its rear surface 1002' . The inclination of the surface preferably correspond to the inclination of the cut off edge 1006' of each furniture panel, or wall 1006a-c. If the furniture module comprises an interior wall 1006c, it is realized that the back piece 1002a-b is preferably not connected to a first and a second side wall 1006a-b but instead a first back piece 1002a is connected to a first side wall 1006a and to the interior wall 1006c. The interior wall 1006c is then, in turn, connected to a second back piece 1002b, and the second back piece 1002b is connected to the second side wall 1006b. Obviously it is even possible to have more than one interior wall 1006c if very wide furniture modules are required.
