A coupling element includes at least one coupling member having a first end and a second end, wherein the coupling member has a flat face on a first side thereof, at least one barb extending in cantilever manner from the flat face and depending away from the first end so as to hinder or prevent the removal of the coupling element from a bore in a surface of a first article into which the coupling member has been inserted from the first end.

A method of assembling a set of panels, to obtain an assembled product, including connecting a first edge of a first panel, with a first main plane, to a first edge of a second panel, with a second main plane, including arranging a third panel with a third main plane perpendicular to the first main plane, arranging a first edge of the third panel at a second edge of the second panel and arranging the third main plane with a second angle in relation to the second main plane; connecting the first edge of the third panel to the second edge of the second panel, by displacing the third panel and/or the second panel; and connecting a second edge of the third panel to a second edge of the first panel and connecting the first edge of the third panel to the second edge of the second panel.

A magnetic assembly structure has a main body and an inserting component. A first engagement slot of the main body receives a first magnetic component, and a first receiving slot of the main body penetrates a main body surface to form a main body opening on the main body surface. The first engagement slot and the first receiving slot are communicated with each other. The inserting component is inserted into the first receiving slot via the main body opening, and the first magnetic component moves into the first magnetic component receiving slot of the inserting component. The magnetic assembly is assembled with a less force, has higher safety, and is hard to be disassembled without allowance or explanations.

A modular outdoor kitchen assembly that includes panels that can be assembled without the use of tools or fasteners. The kitchen assembly may include a front panel and back panel that are attached by side panels that span between the front panel and the back panel. A countertop may be coupled to the top edges of the panels. Cutouts may be formed through the countertop and the one or more of the modular panels to create space for the installation of a grill or other appliances within the outdoor kitchen assembly. Vent openings may be defined through the modular panels to allow expulsion of gases and cooling within the interior space of the kitchen assembly.

A set of panels including a first panel with a first main plane and a second panel with a second main plane with a second main surface. The first and second main planes are essentially perpendicular in a locked position. The first and the second panel include a locking device for locking a first edge of the first panel to a second edge of the second panel. The locking device includes an edge groove wherein the edge groove includes a tongue, which is configured to cooperate with a tongue groove of the first panel, in a locked position, for locking the first and the second edges in a first direction which is perpendicular to the first main plane. A first groove surface of the edge groove cooperate with second main surface to lock the first and second panel in a second direction which is perpendicular to the second main plane.

Modular building blocks may be used to provide furniture or other items. Each modular building block has a number of interleaved layers that provide first and second arms of the building block. Each modular building block comprises a first engageable finger section formed from one or more of the interleaved layers and a second engageable finger section formed from two or more interleaved layers. The second engageable finger section of one modular building block receives the first engageable finger section of another modular building block allowing various arrangements to be assembled.

A single dovetail tenon joint mechanism has a first panel and a second panel; the first panel is provided with a single dovetail tenon groove; the cross-section of the single dovetail tenon groove is a right-angled trapezoid; the right-angle sides of the right-angled trapezoid are near the edge side of the first panel; the long base of the right-angled trapezoid is located at the deepest part of the single dovetail tenon groove; one end of the second panel is provided with a single dovetail tenon that matches the single dovetail tenon groove. The single dovetail tenon is wedged into the single dovetail tenon groove for attachment therewith. During installation, a single dovetail tenon can be inserted from one end of the single dovetail tenon groove, thereby attaching the first panel to the second panel.

A set of panels including a first panel with a first main plane and a second panel with a second main plane. The first and the second panel are provided with a mechanical locking device for locking a first edge of the first panel to a second edge of the second panel at a junction plane, wherein the first main plane is essentially perpendicular to the second main plane and the junction plane is extending between the first main plane and the second main plane. The first edge includes an edge tongue that extends from the junction plane. The second edge includes an edge groove at the junction plane. The edge tongue is configured to cooperate with the edge groove for locking together the first and the second edges in a first direction which is perpendicular to the first main plane. The edge tongue includes a tongue groove.

A set of panels including a first panel, a second panel and a mechanical locking device for locking the first panel to the second panel. The first panel includes a first edge and a first panel surface and the second panel includes a second edge and a second panel surface. The first edge includes a first edge reinforcement in a first edge reinforcement groove, wherein the first edge reinforcement groove is a first drill hole, and/or the second edge includes a second edge reinforcement, wherein the second edge reinforcement is in a second edge reinforcement groove, wherein the second edge reinforcement groove is a second drill hole.

Panels are shown which are provided with a mechanical locking system allowing perpendicular connection with a snap action. A set of panels including a first and a second panel, an edge of the second panel is insertable into a groove of the first panel, when the panels are arranged essential perpendicular to each other, to obtain a mechanical connection between the first and the second panel, when the second panel is displaced essentially perpendicularly to the first panel.
