Fig. 1 illustrates a consumer mountable piece of furniture 1 . By "consumer mountable piece of furniture" is meant a piece of furniture that a customer buys as a kit of furniture parts in a store and the customer then mounts the parts of the kit together in hers or his own home to form the piece of furniture. The customer would be expected to have the skills of the average private person, and would only be expected to use ordinary tools, if any, that are available in most private homes or that could be provided together with the kit of parts when sold at the store. Examples of such ordinary tools include a screw driver and a hex key. The piece of furniture 1 , which in this embodiment is a book case, comprises a cabinet part 2 which is mounted on legs 4 and which supports first and second shelves 6 and 8 that are adapted for storing various objects 9, such as books, decorative objects, pieces of clothing, etc.

The cabinet part 2 comprises a horizontal bottom part 10, a horizontal top part 12, and first and second side walls 14, 16. A first bent corner furniture connecting piece 18 connects the horizontal bottom part 10 to the first side wall 14, a second bent corner furniture connecting piece 20 connects the first side wall 14 to the horizontal top part 12, a third bent corner furniture connecting piece 22 connects the horizontal top part 12 to the second side wall 16, and a fourth bent corner furniture connecting piece 24 connects the second side wall 16 to the horizontal bottom part 10. As will be described in more detail hereinafter, a customer buys a kit of parts comprising the bent corner furniture connecting pieces 18, 20, 22, 24, the bottom and top parts 10, 12, the first and second side walls 14, 16, the shelves 6, 8, and the legs 4 as separate parts, and the customer then mounts them together to form the ready piece of furniture 1 illustrated in Fig. 1. While the legs 4 and the shelves 6, 8 could be mounted in any per se known manner, the way of mounting the cabinet 2, and the specific pieces included therein, will be described in more detail hereinafter.

Fig. 2a illustrates pieces for forming a type of frame used in each of the bent corner furniture connecting pieces 18, 20, 22, 24 illustrated in Fig. 1 . These pieces include a first curved end section piece 26, having the general shape of a banana, and opposite thereto, a second curved end section piece 28, also having the general shape of a banana. Furthermore, a first rod-shaped connecting piece 30 is adapted to extend from the first end section piece 26 to the second end section piece 28. A second rod-shaped connecting piece 32 is arranged to be parallel to the first connecting piece 30 and to extend from the first end section piece 26 to the second end section piece 28. Each of the end section pieces 26, 28 and the connecting pieces 30, 32 is made from a wood based material, for example from pure wood or of a wooden based material, such as chipboard material, particle board material, MDF board material, HDF board material.

Optionally, one or more banana-shaped support pieces 34 may be arranged parallel to the first and second end section pieces 26, 28, and between the end section pieces 26, 28, to connect the first and second connecting pieces 30, 32 in at least one position between the end section pieces 26, 28 to form a reinforcement of the frame.

Fig. 2b illustrates an assembled frame 36 intended for forming a bent corner furniture connecting piece.

A first distal end 38 of the first banana-shaped end section piece 26 has been connected to a first distal end 40 of the first rod-shaped connecting piece 30. A second distal end 42 of the first banana-shaped end section piece 26, which second distal end 42 is opposite to the first distal end 38, has been connected to a first distal end 44 of the second rod-shaped connecting piece 32. Furthermore, a first distal end 46 of the second banana-shaped end section piece 28 has been connected to a second distal end 48, which is opposite to the first distal end 40, of the first rod-shaped connecting piece 30. A second distal end 50 of the second banana-shaped end section piece 28, which second distal end 50 is opposite to the first distal end 46, has been connected to a second distal end 52, which is opposite to the first distal end 44, of the second rod-shaped connecting piece 32. Each of the connections between the banana-shaped end section pieces 26, 28 and the rod-shaped connecting pieces 30, 32 can be formed by, for example, gluing, and/or screw attachment, and/or other attachment means.

In the embodiment shown in Fig. 2b the first and second rod-shaped connecting pieces 30, 32 are embraced between the banana-shaped end section pieces 26, 28. It will be appreciated that other arrangements are possible, for example with the banana-shaped end section pieces 26, 28 being embraced between the first and second rod-shaped connecting pieces 30, 32.

Optionally, the banana-shaped support piece 34 may be connected to the rod-shaped connecting pieces 30, 32 to obtain further support to the frame 36.

The ready-made frame 36 thereby obtains the general shape of a cradle undercarriage.

Fig. 2c illustrates a pressing arrangement 54 for forming a bent corner furniture connecting piece. The pressing arrangement 54 comprises a stamp 56 and a die 58. The stamp 56 has a convex outer face 60, and the die 58 has a matching concave recess 62. When forming a bent corner furniture connecting piece the frame 36, an outer surface layer 64 and an inner surface layer 66 are introduced into the pressing arrangement 54. Each of the outer and inner surface layers 64, 66 is preferably made from wood or a wooden based material, such as chipboard material, particle board material, MDF board material, HDF board material.

The outer surface layer 64 is placed on top of the concave recess 62 of the die 58. An outer face 68 of the outer surface layer 64 faces the concave recess 62. An inner face 70, which is opposite to the outer face 68, of the outer surface layer 64 may be provided with a layer of glue 72. The layer of glue 72 could, for example, be a heat setting glue or any other type of suitable glue.

The frame 36 is placed on top of the outer surface layer 64, with the convex part 74 of the frame 36 facing the inner face 70 of the outer surface layer 64.

The inner surface layer 66 is placed on top of the frame 36. An outer face 76 of the inner surface layer 66 faces the convex outer face 60 of the stamp 56. An inner face 78, which is opposite to the outer face 76, of the inner surface layer 66 may be provided with a layer of glue 80 and faces the concave part 82 of the frame 36. The layer of glue 80 could, for example, be a heat setting glue or any other type of suitable glue.

Hence, the frame 36, having the shape of a cradle undercarriage, is sandwiched between the outer and inner surface layers 64, 66. Optionally the convex part 74 and/or the concave part 82 of the frame 36 could be provided with respective layers of glue 84, 86. These layers of glue 84, 86 could be provided as alternative to, or in combination with the layers of glue 72, 80 of the surface layers 64, 66.

The pressing arrangement 54 may be provided with a heating system, schematically shown as a heating block 88 by means of which a heating to a temperature of, for example, 50-200°C, can be achieved during the pressing sequence.

Fig. 2d is a perspective view and illustrates the pressing arrangement 54 when forming the bent corner furniture connecting piece by pressing, by means of the stamp 56, the inner surface layer 66, the frame 36 and the outer surface layer 64 down into the concave recess 62 to thereby bend the outer and inner surface layers 64, 66 around the frame 36. The stamp 56 maintains the position of Fig. 2d until the glue has set and is then retracted, such that the frame 36 being connected to, and sandwiched between, the surface layers 64, 66 can be removed from the pressing arrangement 54.

Fig. 2e illustrates the frame 36 being sandwiched between the outer and inner surface layers 64, 66 after removal thereof from the pressing arrangement 54. As can be seen the outer and inner surface layers 64, 66 extend beyond the frame 36, as an effect of the outer and inner surface layers 64, 66 being oversized relative to the frame 36. In a cutting step the surface layers 64, 66 and also the frame 36 are machined to obtain well-defined connecting surfaces, as will be described hereinafter with reference to Fig. 2f.

Fig. 2f illustrates the ready-made first bent corner furniture connecting piece 18. At opposite ends of a central bent corner section 89 of the first bent corner furniture connecting piece 18 a machined first connecting surface 90 has been formed in the first rod-shaped connecting piece 30 of the frame 36, and a machined second connecting surface 92 has been formed in the second rod- shaped connecting piece 32 of the frame 36. The first and second connecting surfaces 90, 92 have been machined to narrow tolerances, and are, in this embodiment, at an angle oc1 of 90° to each other. In other embodiments, the angle oc1 could have other values, such as 25-140°, for example if there is a desire to provide a bent corner which is not at exactly 90°. Preferably, the ready-made first bent corner furniture connecting piece 18 has an inner radius Ri of 50 to 150 mm, and a total thickness Ttot of 15-50 mm. These dimensions provide for a combination of high strength and low weight.

The ready-made first bent corner furniture connecting piece 18 has a hollow interior space IS, which is formed by the frame 36 and the surface layers 64, 66. The hollow interior space IS in combination with the frame 36 provides the bent corner furniture connecting piece 18 with a low weight, and still maintains a high mechanical stability.

The machined first connecting surface 90 of the first rod-shaped connecting piece 30 is provided with a first connecting arrangement 93 comprising first and second connecting devices in the form of first and second female parts 94, 96 that are arranged at a distance from each other, as seen along the rod-shaped connecting piece 30. The female parts 94, 96 could preferably be formed by milling. Hence, the first connecting arrangement 93 is arranged in a first end 95 of the central bent corner section 89. In accordance with one embodiment the female parts 94, 96 have the general shape of a key hole. In accordance with one embodiment, the female parts 94, 96 could be arranged for snap-in-connection to corresponding male parts, as will be described in more detail hereinafter. For example, the female parts 94, 96 may preferably have a shape of the type described in US 2014/0205373, see Figs. 14A to 14H of that document. Similarly, the machined second connecting surface 92 of the second rod-shaped connecting piece 32 is provided with a second connecting arrangement 97 comprising first and second connecting devices in the form of first and second female parts 98, 100 that are arranged at a distance from each other, as seen along the rod- shaped connecting piece 32. Hence, the second connecting arrangement 97 is arranged in a second end 99, opposite to the first end 95, of the central bent corner section 89. The female parts 98, 100 could preferably be of a similar design as the female parts 94, 96.

Optionally, the surfaces 64, 66 of the first bent corner furniture connecting piece 18 could be painted, or could be embossed or provided with veneers or foils to obtain a desired visual appearance of the connecting piece 18.

Preferably, the second, third and fourth connecting pieces 20, 22, 24 all have a design which is similar to that of the connecting piece 18. Fig. 3a illustrates the mounting of the piece of furniture 1 illustrated in Fig. 1. In Fig. 3a it is illustrated how the first bent corner furniture connecting piece 18 is connected to the first side wall 14, but it will be appreciated that the other connecting pieces 20, 22, 24, the second side wall 16, the top and bottom parts 10, 12 are assembled according to similar principles to form the piece of furniture 1.

Hence, in accordance with this principle of assembling the piece of furniture, the first side wall 14 has a machined connecting surface 102. The machined connecting surface 102 of the first side wall 14 is provided with first and second male parts 104, 106 that are arranged in positions that correspond to the positions of the female parts 94, 96. In accordance with one embodiment the male parts 104, 106 have the general shape of a key adapted for co-operation with a key hole female part. In accordance with one embodiment, the male parts 104, 106 could be arranged for snap-in-connection to corresponding female parts 94, 96, as will be described in more detail hereinafter. For example, the male parts 104, 106 may preferably have a shape of the type described in US 2014/0205373, see Figs. 14A to 14H of that document.

In the enlarged part of Fig. 3a it can clearly be seen how the male part 106 is arranged in the machined connecting surface 102 of the first side wall 14, and the female part 96 is arranged in the first connecting surface 90 of the connecting piece 18. The female part 96 has a larger end 108 into which the male part 106 may be inserted in a first step of connecting the first side wall 14 to the connecting piece 18. A smaller end 1 10 of the female part 96 is provided with ridges 1 12 that are adapted to cooperate, preferably in a snap-in-connection manner, with grooves 1 14 of the male part 106 in a second step of connecting the first side wall 14 to the connecting piece 18.

Fig. 3b illustrates, in cross-section, how the male part 106 of the first side wall 14 has been inserted into the larger end 108 of the female part 96, and is subsequently moved, in the direction of the arrows A, toward the smaller end 1 10 of the female part 96 to make the ridges 1 12 of the smaller end 1 10 of the female part 96 cooperate and lock, preferably in a snap-in-connection manner, with the grooves 1 14 of the male part 106. Fig. 3c illustrates how the male part 106 is in a locked position inside the smaller end 1 10 of the female part 96, and the first side wall 14 is thereby locked to the first bent corner furniture connecting piece 18. In a similar manner the bottom and top parts 10, 12 and the side walls 14, 16 are connected to the bent corner furniture connecting pieces 18, 20, 22, 24 to thereby obtain the final cabinet 2 illustrated in Fig. 1 .

It will be appreciated that numerous variants of the above described embodiments are possible within the scope of the appended claims.

Hereinbefore it has been described, with reference to, e.g., Fig. 2f, that the first and second connecting arrangements 93, 97 are arranged at an angle oc1 of 90° to each other. This is a suitable angle for a bent corner furniture connecting piece adapted for connecting first and second furniture pieces 14, 10 that are to be arranged in a 90° relation to each other. If, for example, first and second furniture pieces are to be in a 135° relation to each other, then the first and second connecting arrangements 93, 97 would be arranged at an angle oc1 of 45° to each other. Hence, the first and second connecting arrangements 93, 97 may be arranged at an angle oc1 of 25-140° to each other. For many furniture applications first and second furniture pieces 14, 10 are arranged in either a right angled or an obtuse relationship. Hence, the angle oc1 is preferably 25-90°.

Hereinbefore it has been described that the first and second connecting arrangements 93, 97 each comprises two connecting devices 94, 96 and 98, 100, respectively. It will be appreciated that the first and second connecting arrangements could also comprise other numbers of connecting devices depending on the required stability. Typically, each of the first and second connecting arrangements would comprise one to six connecting devices, and preferably two to four connecting devices.

Hereinbefore it has been described, with reference to Fig. 2f, that the first and second connecting devices 94, 96 of the first connecting arrangement 93 are entirely formed in the first rod-shaped connecting piece 30, and that the first and second connecting devices 98, 100 of the second connecting arrangement 97 are entirely formed in the second rod-shaped connecting piece 32. According to alternative embodiments, one or more of the connecting devices 94, 96, 98, 100 comprised in the first and second connecting arrangements 93, 97 could be formed partly in the respective rod-shaped connecting piece 30, 32 and partly in another object, for example in the respective end-section piece 26, 28. Hence, the connecting devices 94, 96, 98, 100 comprised in the connecting arrangements 93, 97 are preferably at least partly formed in the respective rod-shaped connecting piece 30, 32.

Hereinbefore it has been described that the consumer mountable piece of furniture is a book case. It will be appreciated that the present invention may be applied also in other pieces of furniture, including for example wardrobes, wall shelves, chests of drawers, television benches, cabinets, sideboards, tables, storage furniture, chairs etc.
