Abstract

A set of panels including a panel with a first main plane and an adjacent panel with a second main plane, wherein the panel and the adjacent panel are provided with an angleable locking device for locking a first edge of the panel to a second edge of the adjacent panel. The first main plane is essentially perpendicular to the second main plane. The angleable locking device includes an edge groove at the first edge and a tongue groove at the second edge. The edge groove includes a flexible tongue arranged in an insertion groove at a first side of the edge groove. The angleable locking device is configured to be unlocked by an angling motion of the panel relative the adjacent panel, such that an angle between the first and the second main plane increases.

First claim

The invention claimed is:

1. A method for disassembling a furniture product comprising a frame, first and second corner locking devices and a back piece, the frame including a top panel, a first lateral panel and a second lateral panel, the first and second corner locking devices configured to lock the top panel respectively to the first and second lateral panels, and the first and second lateral panels being locked to the back piece, wherein the method comprises:
unlocking the first corner locking device, at a first corner edge of the top panel, by displacing at least part of a first flexible tongue of the first corner locking device prior to displacing the first corner edge relative to the first lateral panel;
unlocking the second corner locking device, at a second corner edge of the top panel, by displacing at least part of a second flexible tongue of the second corner locking device prior to displacing the second corner edge relative to the second lateral panel;
prior to relative displacement of the top panel away from the back panel, angling up the top panel by an angling motion;
unlocking, by said angling motion, an angleable locking device connecting the back piece to the top panel, to allow displacement of the top panel away from the back piece; and
removing the top panel, while the first and second lateral panels remain locked to the back piece.

2. The method as claimed in claim 1 , wherein the frame further includes a bottom panel, and the method further comprises:
rotating the furniture product,
unlocking a third corner locking device and a fourth corner locking device, at a third corner edge and at a fourth corner edge of the bottom panel, respectively, by displacing at least part of a third flexible tongue of the third corner locking device and at least part of a fourth flexible tongue of the fourth corner locking device, respectively,
angling up the bottom panel by another angling motion, and
unlocking by said other angling motion the back piece connected to the bottom panel by another angleable locking device, and removing the bottom panel.

3. The method as claimed in claim 2 , wherein the displacing of the at least part of the third flexible tongue of the third corner locking device is performed prior to displacing the third corner edge relative to the first lateral panel, and the displacing of the at least part of the fourth flexible tongue of the fourth corner locking device is performed prior to displacing the fourth corner edge relative to the second lateral panel.

4. The method as claimed in claim 2 , wherein the angling up of the bottom panel is performed prior to relative displacement of the bottom panel away from the back panel.

5. The method as claimed in claim 2 , wherein the unlocking by said other angling motion unlocks the other angleable locking device to allow displacement of the bottom panel away from the back piece.
