Abstract

A bent corner furniture connecting piece (18) comprises a central bent corner section (89) having a first connecting arrangement (93), and a second connecting arrangement (97). The connecting piece (18) comprises a wooden frame (36) comprising a first and a second curved end section piece (26, 28). First and second connecting pieces (30, 32) connect the first and second curved end section pieces (26, 28). The first connecting piece (30) is provided with the first connecting arrangement (93) for connection to a first furniture piece, and the second connecting piece (32) is provided with the second connecting arrangement (97) for connection to a second furniture piece. A bent outer surface layer (64) is arranged on a convex part (74) of said frame (36), and a bent inner surface layer (66) is arranged on a concave part (82) of said frame (36).

First claim

The invention claimed is:

1. A bent corner furniture connecting piece comprising:
a central bent corner section, a first connecting arrangement arranged in a first end of the central bent corner section and adapted for connection to a first furniture piece, and a second connecting arrangement arranged in a second end of the central bent corner section, which second end is opposite to the first end, and adapted for connection to a second furniture piece,
wherein the first and second connecting arrangements are arranged at an angle of 25-140° to each other,
wherein the bent corner furniture connecting piece comprises a wooden frame comprising a first curved end section piece and a second curved end section piece, a first connecting piece connecting the first and second curved end section pieces at respective first ends thereof, and a second connecting piece, which is parallel to the first connecting piece, connecting the first and second curved end section pieces at respective second ends thereof, said second ends being opposite to said first ends of said curved end section pieces,
wherein said first connecting piece is provided with at least a part of the first connecting arrangement for connection to a first furniture piece,
wherein said second connecting piece is provided with at least a part of the second connecting arrangement for connection to a second furniture piece,
wherein a bent outer surface layer is arranged on a convex part of said frame, and
wherein a bent inner surface layer is arranged on a concave part of said frame so that the outer surface layer is spaced from the inner surface layer by the first connecting piece, the second connecting piece, the first curved end section, and the second curved end section.

2. A bent corner furniture connecting piece according to claim 1 , wherein the first connecting arrangement is arranged for snap-in-connection to the first furniture piece.

3. A bent corner furniture connecting piece according to claim 2 , wherein the second connecting arrangement is arranged for snap-in-connection to the second furniture piece.

4. A bent corner furniture connecting piece according claim 1 , wherein the first connecting arrangement comprises at least a first connecting device of which at least a part is arranged in the first connecting piece, and wherein the second connecting arrangement comprises at least a first connecting device of which at least a part is arranged in the second connecting piece.

5. A bent corner furniture connecting piece according to claim 4 , wherein the first connecting devices of the bent corner furniture connecting piece are arranged for snap-in-connection to the first and second furniture pieces, respectively.

6. A bent corner furniture connecting piece according claim 1 , wherein the first and second connecting arrangements are arranged for releasable connection to the first and second furniture pieces, respectively.

7. A bent corner furniture connecting piece according to claim 1 , wherein the first and second connecting arrangements of the bent corner furniture connecting piece each comprises one part of a female-and-male connecting arrangement.

8. A bent corner furniture connecting piece according to claim 7 , wherein at least the first connecting arrangement of the bent corner furniture connecting piece comprises at least one female part.

9. A bent corner furniture connecting piece according to claim 1 , wherein at least the first connecting arrangement of the bent corner furniture connecting piece comprises one part of a key and key hole connecting arrangement.

10. A bent corner furniture connecting piece according to claim 1 , wherein the inner and outer surface layers are made from wood or a wooden based material, such as chipboard material, particle board material, MDF board material, HDF board material.

11. A bent corner furniture connecting piece according to claim 1 , wherein the bent corner furniture connecting piece has an inner radius of 50 to 150 mm.

12. A bent corner furniture connecting piece according to claim 1 , wherein the bent corner furniture connecting piece has a total thickness of 15-50 mm.

13. A bent corner furniture connecting piece according to claim 1 , wherein the bent corner furniture connecting piece has a hollow interior space.

14. A method of forming a bent corner furniture connecting piece adapted for connection to a first furniture piece and to a second furniture piece in the assembly of a piece of furniture, the method comprising:
forming a wooden frame by connecting a first connecting piece to first and second curved end section pieces at respective first ends thereof, and connecting a second connecting piece to the first and second curved end section pieces at respective second ends thereof,
applying an outer surface layer on a convex part of said frame,
applying an inner surface layer on a concave part of said frame so that the outer surface layer is spaced from the inner surface layer by the first connecting piece, the second connecting piece, the first curved end section, and the second curved end section,
arranging at least a first connecting arrangement, adapted for connection to a first furniture piece, at least partly in the first connecting piece, and
arranging at least a second connecting arrangement, adapted for connection to a second furniture piece, at least partly in the second connecting piece.

15. A method according to claim 14 , wherein the outer and inner surface layers are glued to the frame.

16. A method according to claim 14 , wherein said steps of applying an outer surface layer on a convex part of said frame and applying an inner surface layer on a concave part of said frame involves sandwiching the frame between the outer and inner surface layers and pressing the sandwiched structure obtained thereby in a pressing arrangement comprising a die and a stamp.

17. A method according to claim 16 , wherein said step of pressing the sandwiched structure further involves heating the sandwiched structure to a temperature in the range of 50-200° C.

18. A method according to claim 16 , wherein a layer of glue is applied on the frame and/or on the outer and/or inner surface layers prior to pressing the sandwiched structure.

19. A method according to claim 16 , wherein the frame is sandwiched between oversized outer and inner surface layers that are subsequently machined to fit with the frame.

20. A method according to claim 14 , wherein said step of arranging at least a first connecting arrangement for connection to a first furniture piece in the first connecting piece includes milling at least one female part at least partly in the first connecting piece.

21. A consumer mountable piece of furniture, comprising at least one bent corner furniture connecting piece comprising:
a central bent corner section, a first connecting arrangement arranged in a first end of the central bent corner section and adapted for connection to a first furniture piece, and a second connecting arrangement arranged in a second end of the central bent corner section, which second end is opposite to the first end, and adapted for connection to a second furniture piece,
wherein the first and second connecting arrangements are arranged at an angle of 25-140° to each other,
wherein the bent corner furniture connecting piece comprises a wooden frame comprising a first curved end section piece and a second curved end section piece, a first connecting piece connecting the first and second curved end section pieces
