An attachment assembly for use with furniture and other articles. The attachment assembly includes a connector assembly that is configured to engage with a rail. The connector assembly includes a first, fixed protrusion, a lever, a second protrusion extending from the lever, and a third protrusion positioned between the first protrusion and the second protrusion. The rail includes a lip and a cutout in the lip that is sized to receive the third protrusion. The rail is configured to retain the connector assembly. Pivoting the lever when the connector assembly is positioned within the rail is configured to cause the second protrusion to bear against a bottom surface of the rail, such that the first protrusion and the second protrusion frictionally engage the bottom surface of the rail and the third protrusion frictionally engages the lip to fixedly hold the connector assembly.

A leg-plate joinery assembly includes a metal plate portion having a first set of one or more apertures and a second set of one or more apertures, a leg portion having one or more bore holes, wherein each bore hole includes a narrow portion and a wide portion, a first set of one or more mechanical fasteners configured to pass through corresponding apertures of the first set of one or more apertures such that each mechanical fastener is received in a corresponding, aligned one of the one or more bore holes, and a second set of one or more mechanical fasteners, wherein each mechanical fastener in the second set of one or more mechanical fasteners configured to pass through a corresponding aperture of the second set of one or more apertures. An epoxy composition is configured to be received in each of the one or more bore holes.

An one-piece corner connector for connecting two frame bars at right angles to one another includes a right-angle bracket having two angle legs, an intermediate plate, and two U-profile connecting pieces at right angles, having a middle leg and two side legs for insertion into the plug-in openings in the frame bars which are open at one end. The middle legs of the U-profile connecting pieces are formed on and run with their outer side parallel to the intermediate plate. The one outer side legs of the U-profile connecting pieces are each formed on one of the angle legs and run with their outer side parallel to the outer side of the angle leg. The other inner side legs of the U-profile connecting pieces are connected to one another by means of a wall element which is angled from the intermediate plate.

Pivoting the lever when the connector assembly is positioned within the rail is configured to cause the second protrusion to bear against a bottom surface of the rail, such that the first protrusion and the second protrusion frictionally engage the bottom surface of the rail and the third protrusion frictionally engages the lip to fixedly hold the connector assembly.

A connecting device for connecting a table leg to a table leaf having a back-gripping element, which can be disposed on the table leaf and has an engagement hole and a locking device, which can be disposed on the table leg. The locking device has a clamping element having an engagement hook which is designed to engage the engagement hole of the back-gripping element, a spring element, which is supported at least indirectly against the clamping element and at least indirectly against a spring abutment, and an actuating element. The actuating element acts on the spring abutment so that, in a locking position, the spring abutment applies sufficient force to secure the engagement hook of the clamping element in the engagement hole, and in an unlocking position, the spring abutment is in a position in which the spring element is at least partially unloaded in relation to the locking position.

A fastening mechanism configured to connect a first member to a second member may have a clamp member having an enclosure for enclosing the first member. The mechanism may also have engagement sheets extending from two side edges of the enclosure. Each engagement sheet may have a first engagement portion. The mechanism may also have a locking member having slots where the engagement sheets of the clamp member may be configured to be inserted through the slots. The mechanism may also have an actuating and tensioning device having a main body portion provided with second engagement portions engaged with the first engagement portions, and a force application mechanism affixed to the main body portion for applying a force on the locking member to shift the relative position between the locking member and the clamp member. A furniture assembly using the fastening mechanism is also provided.

A display system is provided and include base panel, a collapsible structure, a structure connector, and a base connector. The collapsible structure includes a pair of modular display panels with a pair of panel connectors that receive one another. The structure connector includes a pair of planar body sections angled with respect to each and connects to the pair of modular display panels. The base connector connects the collapsible structure to the base panel and includes a first planar body section secured to the collapsible structure, a second planar body section positioned adjacent to the first planar body section and secured to the collapsible structure, and a third planar body section positioned adjacent to the first planar body section and the second planar body section and secured to the base panel.

A joint assembly includes a structural body having a key which projects cantilevered from an abutment surface. The key includes a stem with a first stem portion having a reduced transverse encumbrance, and a second stem portion from which fins project and define locking surfaces. A seat body includes an abutment counter-surface facing the abutment surface. A seat is formed by opening from the abutment counter-surface, which delimits a key entry slot. A first seat portion proximate the entry slot allows insertion of the key if the fins are aligned with the entry slot. A second seat portion internal and opposite the entry slot widens to allow free rotation of the key. The seat body forms locking counter-surfaces having an inclined plane portion moving away from the entry slot so that key rotation brings the abutment surface in force-contact against the abutment counter-surface, creating a firm frictional fit.

A chair (1) wherein the back rest (10) comprises two elongated connection members (11a, 11b) each provided with a hole (12a) extending along a crossing direction (T). The respective leg (20a, 20b) is provided with a first bore (21a) extending along a longitudinal direction (L) and a second bore (22a) extending along the crossing direction (T), connecting with the first bore (21a). The first bore (21a) is configured to receive a portion of the elongated connection member (11a). The corner pieces (31a, 31a′) are provided with a through-going hole (32a) being configured to be in register with the hole (12a) of the elongated member (11a) and the second bore (22a) of the leg (20a, 20b). The chair (1) further comprises a first and a second fastening arrangement (40) extending through the through-going hole (32a) and through the second bore (22a) into the hole (12a) of the elongated connection member (11a) to interconnect the back rest (10), the legs (20a, 20b) and the corner pieces (31a, 31b, 31a′). The disclosure also relates to a kit of parts configured to be assembled into a chair.
