The furniture having, between two lower and upper boards, each having two parallel planar surfaces and two front and rear edges, a module with one or two side walls, each having two upper and lower edges, and a rear back wall with two upper and lower edges, assembled to the side walls. The module can slide and be guided along the boards. One of the edges of each board having a longitudinal rib protruding perpendicular to its planar surfaces. The module is notched longitudinally and perpendicular to its side walls so as to slot onto the ribs of the boards and thus slide along these ribs.

A multifunctional modular furniture unit and system is developed to build a various type of furniture and housing and office accessories that are used in interior design. The multifunctional modular furniture system comprises a plurality of modular units and a plurality of support units. The modular units comprise a top block unit, a link block unit, and a bottom block unit. The support units comprise a support strap and a connection cap. The various furniture can be built utilizing attaching the modular units to each other and using the support units to reinforce a furniture structure.

Building panels including a first and a second panel and including a locking device. The locking device includes a tongue and an edge groove provided in the second panel and the first panel, respectively, wherein the tongue and the edge groove are configured to cooperate with each other for locking a first edge portion of the first panel to a second edge portion of the second panel in a first direction. The locking device further includes a separate tongue provided in an insertion groove and a tongue groove configured to cooperate with each other for locking the first edge portion to the second edge portion in a second direction. A length of the tongue groove along an edge portion may be smaller than a length of the edge portion. A length of the insertion groove along an edge portion may be smaller than the length of the edge portion.

A connector device comprises a male taper component having a base and a tapering bracket extending therefrom, and a female taper component having a tapering channel. The tapering bracket is releasably received within the tapering channel to effect a firm connection between the male taper component and the female taper component.

A routing jig and tenon fastener comprising of a jig that has a means to index a router the proper pathway to create a mortise in any object, and a means for indexing and installation of a corresponding tenon, specifically a routing jig and tenon fastener that is easily maneuverable, fixed or adjustable, in a form being an adjustable routing jig being comprised of a mortise mounting member and an adjustable indexing member, with different sizes and quadrilateral shapes to allow for smaller or larger mortise to be carved out by a router tool, the ability to index on a corner or edge where a mortise can be created, with means to attach the jig to the surface which allows the jig becomes a guide for a router tool to create a mortise, wherein the jig can be used as an indexing guide for aligning and attaching the uniquely and specifically designed quadrilateral tenon fastener for the mortise created by the routing jig, the tenon designed with specific holes, slots, grooves, or mounting options for attaching table legs or other objects, and the specifically placed holes, slots, and grooves allow for different sized screws and fasteners to be installed flush to the tenon.

A set of panels including a first panel and a second panel configured to assume a locked state in which a first main plane of the first panel is arranged at an angle of between 30° and 150° relative to a second main plane of the second panel. A separate tongue arranged in an insertion groove of a groove is configured to cooperate with a tongue groove provided in an edge section of the second panel for locking the first and second panels to each other in a first direction perpendicular to the first main plane, and the edge section is configured to cooperate with the groove for locking the first and second panels to each other in a second direction parallel to the first main plane. A bottom portion of the groove includes an elevated portion arranged at least in an outer section of the groove along the second direction, wherein an area of the elevated portion is at least 3% of an area of a rectangular bounded region extending along boundaries of the bottom portion.

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 present invention provides a connection system for removably connecting first and second pieces one to another. The connection system comprises: a tapering recess formed in, or connected to, the first piece. The tapering recess has an opening which is shaped and dimensioned to receive a wedge formed in, or connected to, the second piece. The wedge has a dovetail profile which is adapted to engage with walls of the recess.

The wedge is shaped and dimensioned to slide in a first direction and thereby wedge into the tapered recess. Each piece has at least one aperture which receives a lock piece. The first and second pieces when connected and which when oriented in a user preferred direction, cause the lock piece to fall from a first aperture into a second aperture, thereby locking the wedge in the tapering recess and preventing movement in an opposite sliding direction.

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.
