A modular chair assembly includes a seat member and at least three support leg units. The seat unit includes a seat member which has a lower surface and an upper surface opposite to the lower surface. Each of the three support leg units is detachably mounted to the lower surface of the seat member, and includes an inner axle and a hollow tube sleeved on the inner axle. The inner axle and the hollow tube are made of different materials to permit the inner axle to have a larger anti-bending strength than the hollow tube. The inner axle includes a bottom end surface for being supported on the ground.

The present invention relates to an interlocking means for connecting a first panel, second panel and a leg of a piece of furniture with each other, wherein the interlocking means comprises an elongated element and a brace element. The elongated element comprises a portion configured to be attached to a first surface of the first panel and a first surface of the second panel and either a securing means configured to receive an interconnection element protruding from the leg or an interconnection element configured to match a securing means formed in the leg. The brace element comprises a portion configured to be attached to a second surface of the first panel and a second surface of the second panel and a through opening configured to receive the interconnection element.

A frame for a unitary component of a sectional seating apparatus having a corner portion having a foundation and an elongate lateral portion having a foundation, interconnected by a longitudinal foundation member extending along a back side of the foundations and a transverse foundation member commonly supporting a side edge of the corner portion and supporting a side edge of the lateral portion intermediate opposing ends of the unitary component.

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.

In as first aspect of the invention, this is achieved by a joining system for furniture parts comprising female coupling recess formed in a first furniture part, a male coupling tongue projecting from an adjoining second furniture part, said female coupling recess being adapted to receive the male coupling tongue, said male coupling tongue comprising a first locking element configured for a snap joint interlocking engagement with a matching second locking element in said female coupling recess, the male coupling tongue being configured to be more flexible than the female coupling recess. The joining system comprises an upper guiding surface arranged on a first side of the female coupling recess on the first furniture part, forming an essentially non-resilient guide for the male coupling tongue upon insertion thereof, limiting movement of said male coupling tongue in a direction towards said first side of the female coupling recess. The joining system comprises a lower guiding surface arranged on a second side of the female coupling recess on the first furniture part, located opposite to said first side thereof, said lower guiding surface is configured to force the male coupling tongue to resiliently deflect whilst in engagement with said upper guiding surface upon further insertion thereof in a deflection movement towards said first side of the female coupling recess, until the first locking element of the male coupling tongue snaps together with the matching second locking element of the female coupling recess.

A furniture assembly can include a tabletop with removable legs. The removable legs can be attached to the tabletop with a socket having a threaded member mounted in a non-fixed and anti-rotation registration at the bottom of the socket. The legs can be mounted to the socket by insertion and turning for threaded engagement. The floating engagement mechanism can allow the threaded fastener member to move during installation to provide for enhanced alignability between the leg and the threaded fastener member.

A dovetail-type embedded connecting piece and an office desk are provided. The dovetail tenon type embedded connecting piece includes a dovetail groove and a dovetail tenon in a mortise-tenon connection with the dovetail groove. The dovetail groove includes a main plate and an auxiliary plate detachably connected with the main plate. A first clamping groove and the dovetail groove are formed by the main board and the auxiliary plate in use. The dovetail tenon includes a left side plate and a right side plate detachably connected to the left side plate, and in a use state, a second clamping groove is formed by the left side plate and the right side plate.
