A joint for furniture uses alternating tabs and slots formed along an edge of first and second furniture panels. The panels are joined together so that tabs in the first panel are disposed in slots in the second panel and tabs in the second panel are disposed in slots in the first panel. This arrangement causes the slots to flex outwardly and the tabs to flex inwardly once assembled and creates residual stress in the assembled joint which stiffens the joint.

A modular cabinet assembly has at least a first sub-cabinet and a second sub-cabinet. Each sub-cabinet includes a back board having at least two separate back board pieces that are pivotably connected to each other, a left side board pivotably connected to one of the at least two back board pieces, and a right side board pivotably connected to another of the at least two back board pieces. At least one shelf board having opposite ends is removably connected to the left side board and the right side board of either the first sub-cabinet or the second sub-cabinet. A first end board is connected to either an upper end of the first sub-cabinet or a lower end of the second sub-cabinet. A first connector removably connects the left side boards of the first and second sub-cabinets, and a second connector removably connects the right side boards of the first and second sub-cabinets.

A set 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 surface and a first panel surface, the second panel includes a second panel surface, the first edge surface facing the second panel surface in a locked position of the first and the second panel, the mechanical locking device includes a panel groove at a surface of the second panel, a flexible tongue positioned in the panel groove, a rod-shaped element at the first edge surface and an insertion groove at the second panel surface extending from the second panel surface to the panel groove, the rod-shaped element having a first part at a first end, a second part at a second end and a recess in the second part, and a third part located between the first and second part.

A laminate used to be detachably mounted in the cabinet body is provided. The laminate includes a first surface used to support articles stored in the cabinet body as well as a first side surface adjacent to the first surface, where at least one first coupling portion is formed on the first side surface, and is coupled with the cabinet body to detachably fix the laminate into the cabinet body. The side insertion type laminate of the present disclosure has a greatly simplified structure, and can be used to freely divide the space of the cabinet body.

A set including a first panel, a second panel and a mechanical locking device for locking the first panel to the second panel, the mechanical locking device includes an insertion groove at the second edge surface, a flexible tongue positioned in the insertion groove and an edge tongue including a tongue groove, the flexible tongue includes a first locking surface and a second locking surface, the first locking surface is configured to cooperate with the tongue groove for locking of the first panel to the second panel in a first direction when the flexible tongue is positioned in the insertion groove in a first orientation, the second locking surface of the flexible tongue is configured to cooperate with the tongue groove for a locking of the first panel to the second panel in a first direction when the flexible tongue is positioned in the insertion groove in a second orientation.

The invention provides a side frame, which comprises a frame body formed by connecting vertical columns and a horizontal bar; and a plurality of supporting arms provided on the frame body; the vertical columns are provided with a plurality of mounting holes, two ends of each of the supporting arms are respectively connected with mounting holes of two of the vertical columns of the frame body; one end of the horizontal bar of the frame body is provided with a fixing device for installing the frame body to a wall body. The present invention also provides a storage rack with side frames. The storage rack comprises at least two side frames and a plurality of boards, each of which is positioned between two side frames, and can be detachably connected to the supporting arms on the side frames. The side frames of the present invention have simple structure and strong practicability. The supporting arms of the side frames can form a stable connection with the frame body of the side frames, thereby improving the structural strength of the side frames. The invention of the storage rack with the side racks has better supporting capacity and load bearing effect, thereby improving the practicability and stability of the storage rack.

In a set of panels for an assembled product, a first panel and a second panel may be assembled with a third panel. An end surface of the third panel includes a first tongue and a second tongue. The first panel and the second panel are configured to be arranged with their respective end surfaces facing each other. A first tongue of the third panel is configured to be arranged in an edge groove of the first panel and a second tongue of the third panel is configured to be received in an edge groove of the second panel to join the panels at least in a first direction. The first panel and the second panel may be of a first panel type, and the third panel may be of a second panel type. A corner element may be connected to a side panel of an assembled product.

A multi-compartment storage shelf includes seven connecting boards and inner partitions. The inner partitions each have an engaging groove. At least two of the inner partitions are intersected and interconnected with each other through the engaging grooves of the inner partitions to form a first grid-shaped inner frame. The first grid-shaped inner frame is connected to the first connecting board, the second connecting board, the fourth connecting board, and the fifth connecting board. At least two of the inner partitions are intersected and interconnected with each other through the engaging grooves of the inner partitions to form a second grid-shaped inner frame. The second grid-shaped inner frame is connected to the sixth connecting board and the seventh connecting board, and the third connecting board.

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.

A set including a first panel, a second panel and a mechanical locking device for locking the first panel to the second panel, the mechanical locking device includes an insertion groove at the second edge surface, a flexible tongue positioned in the insertion groove and an edge tongue including a tongue groove, the flexible tongue includes a first locking surface and a second locking surface, the first locking surface is configured to cooperate with the tongue groove for locking of the first panel to the second panel in a first direction when the flexible tongue is positioned in the insertion groove in a first orientation, the second locking surface of the flexible tongue is configured to cooperate with the tongue groove for a locking of the first panel to the second panel in a first direction when the flexible tongue is positioned in the insertion groove in a second orientation.
