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 mechanical clamp system for joining two or more panels or other structural elements together at different angles for the purpose of constructing furniture, product displays, art, play equipment, and other desirable structural elements. The clamp system is comprised of a top member and bottom member, the top member and bottom member being held together by a nut and bolt assembly, and the clamp system having transverse mounting elements capable of affixing the clamp system to a wall or other rigid surface with screws or other attachment mechanisms. First and second end portions of each of the top and bottom members are oriented such that the structural elements are rigidly held at a fixed angle with respect to one another.

A simple engaging device comprises a locating base with at least a longitudinal hole, and at least a locating stem with an engaging head and a joining part corresponding to the longitudinal hole. Two flat locating parts are oppositely disposed at two lateral sides of the longitudinal hole; each flat locating part has a slant plane, a first slender retaining projection, a step, and a second slender retaining projection; the slant plane makes the joining part easy to be assembled and is capable of tightly guiding the joining part to reach the first slender retaining projection at which the joining part can be retained firmly without loosening, and the step and the second slender retaining projection are capable of engaging with the joining part in case of the engaging head and the joining part being worn out.

A bent corner furniture connecting piece (18) comprises a central bent corner section (89) having a first connecting arrangement (93), and a second connecting arrangement (97). The connecting piece (18) comprises a wooden frame (36) comprising a first and a second curved end section piece (26, 28). First and second connecting pieces (30, 32) connect the first and second curved end section pieces (26, 28). The first connecting piece (30) is provided with the first connecting arrangement (93) for connection to a first furniture piece, and the second connecting piece (32) is provided with the second connecting arrangement (97) for connection to a second furniture piece. A bent outer surface layer (64) is arranged on a convex part (74) of said frame (36), and a bent inner surface layer (66) is arranged on a concave part (82) of said frame (36).

A mounting frame for a switchgear cabinet or a rack includes mounting pieces which are arranged, as corner pieces, in the four corner sections of a rectangle or square that extends in an x-y plane, the mounting pieces being produced in a respective shaping process and having outer first and second mounting faces which extend in the x direction and in the y direction at a right angle thereto and which extend in a space direction z at a right angle to the x-y plane, and are provided with hollow spaces which are at least partially surrounded by wall parts and/or bores that are oriented in the z direction. The mounting frame further includes intermediate elements which extend between the mounting pieces in the x direction and in the y direction and the end sections of which are fastened to the mounting pieces. The mounting pieces have wall sections which extend in parallel to the x-y plane, thus making assembly easier.

A modular system for furniture, exhibition structures having wall modules with wall surfaces situated opposite one anotheropposite front and rear surfaces and opposite contact areas, comprising connecting elements connecting the wall modules having L-shaped, T-shaped or cruciform cross-sectional area. The wall modules have a recess for receiving the connecting element which is matched to the shape of the recess. The recess runs from the contact area on one side of the wall module, in the direction of the contact area, on the other side of the wall module and passes through the wall module in the direction of a wall surface to the opposite wall surface, and is situated between sections of the front surface and rear surface which are situated opposite one another. The connecting elements, when they are inserted into the recess in a wall module, correspond to the distance between the wall surfaces.

A lower corner connector for a modular sports goal comprises a first tube having a generally circular inner surface and a second tube extending substantially perpendicularly to the first tube. The first tube has an open end for receiving an upright and a base opposite the open end for resting on a surface. A retainer projects inwardly from the inner surface of the first tube for engaging and retaining the upright and permitting the upright to rock toward and away from the second tube within the first tube to assist in absorbing impact forces.

Building or structural panels may be joined, such as to form walls or floors. The panels may be connected in various orientations via one or more connectors. The connectors may mount to anchors associated with the panels. The panels may have outer skins located over an expanded core comprising a matrix of supporting elongate members and voids or openings, with the anchors located at edges of the panels.

Assembly-type furniture for convenient assembly, and reduced manufacturing cost by enhancing the productivity is provided. To this end, the assembly-type furniture equipped with a press-type bonding member includes a second piece provided with a long groove for bonding on the periphery of at least one side thereof, a first piece that slides onto the long groove of the second piece, and a bonding member that is provided on the second piece in a position that pressurizes one side of the long groove when the one side of the first piece slides along the long groove of the second piece, and maintains the bonded state of the second piece and the first piece in the pressed state.

The connector assembly includes a fitting with a first mounting portion having two opposing surfaces and mounting hole(s) extending between the two surfaces for connecting with a first member. A second mounting portion extends angled with respect to the first mounting portion and has two opposing surfaces and mounting hole(s) extending between the two for connecting with a second member. A joint portion integrally connects the first and second mounting portions. One or more washers each have opposing upper and lower surfaces and at least one hole extending between the two surfaces, each receiving a fastener for attaching the second mounting portion to the second member. The washer lower surface is disposed on the second mounting portion inner surface such that the washer opening is centered about the at least one mounting hole axis. Each washer is joined to the second mounting portion to form an integral assembly.
