Le joint se compose d'une couple d'éléments (1,1') liés aux panneaux juxtaposés (2,2') en correspondance des bords verticaux juxtaposés et liés réciproquement par au moins une petite barre (6) articulée aux deux, et comprenant au moins une couple d'engrengages égaux (5, 5', 13,13'), solidaires auxdits éléments (1,1'), concentriques aux pivots d'articulation (7, 7') de la petite barre (6) et réciproquement engagés.

Le joint permet d'effectuer des mouvements d'ouverture et fermeture des panneaux d'une façon correcte, et il ne pose aucune limitation aux dimensions des panneaux et permet en outre d'obtenir une parfaite situation coplanaire des parois obtenues.

The present invention is about an assembly system for its use in the manufacturing of furniture and other constructive elements and structures, for its possible folding and unfolding, or closing and opening, and fixation of a part in its position of use based on its spatial orientation.

The double assembly system has a group of elements (1), the first group of elements (1) which intersect with another group, and united (Fig. 1.c) they allow a rotational movement (see Fig. 1.d) of a defined and specific angle (ß) of a group of elements (Fig. 1.a) over another (see Fig 1.b) allowing for the union of parts (1f, 1g, 2f, 2g) (see Fig. 2), generally flat ones, so that one of the mentioned parts can pivot, rotate or fold over another according to the aforementioned angle, and stabilize the mentioned part in its final position.

An apparatus having a detaching mechanism includes an operating panel and a detachable member. The operating panel has a support surface. The detachable member is engaged with the operating panel and includes an operating switch. The detachable member has a forward-bent posture and a separation posture to be set when the detachable member is detached from the support surface of the operating panel.

A frictionless hinge arrangement comprises two hinge components (1,2), each having a hinge surface (3,4), the hinge surfaces (3,4) confronting each other, and connected hingedly close together by a plurality of thin pliable connecting straps (11,12), of which each such strap passes between the confronting surfaces (3,4) of the two hinge components (1,2), thus very slightly separating them; the straps (3,4) being disposed in approximately s-shape and reverse s-shape arrangement alternately in one sense and in the other to allow the adjacent hinge surfaces (3,4) to roll on each other (with the straps (11,12) in between) when the hinge is opened or closed, each strap being secured fixed on each side in relation to a respective one of the hinge components; wherein on each side, each of the flexible straps (11,12) is provided with a lug (13,14) accommodated in a slot or socket formation (9,10) associated with one of the hinge parts (thus fixing the lug in relation to one of the hinge parts), so that the slot or socket formation (9,10) retains the lug (13,14) and the associated end of the strap against movement lengthwise relative to the hinge parts (1,2) as well as against disassembly by any pulling-forces exerted on the flexible strap (11,12). The end of the flexible strap that forms part of the snap-in fixing can be accessible by a user's hand or by a tool to allow the complementary formations to be dislodged and thereby disassembled. The hinges (and kits of parts for making them) are applicable for example to fold-up displays, space frames, constructional display systems, folding or other hinged doors and partitions for office furniture, dividers, doors and gates, as well as almost any other application requiring hinge function. In such hinge arrangements the ends of the flexible straps can be provided with springy folded-back tongue extensions to help retain the lugs in engagement with the socket formations.

Eine Falttür besteht aus lotrechten, verschiebbar aufgehängten Platten (1), die an ihren Stoßflächen (7) vorzugsweise V-förmig ausgekehlt sind, und aus Leisten (2), die einen Fugendeckteil (10) und davon in die Auskehlungen (7) der Platten vorspringende Lagerteile (12), insbesondere 45°-Flansche, aufweisen, wobei die Platten durch horizontale Zugfedern (5) mit den Leisten gelenkig verbunden und um die Kanten der Flansche (12) scharnierartig schwenkbar sind.
