Abstract: 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.

Abstract: A modular frame structure (1) of a partition wall made of glass panes, or other pane material, or pane (7), comprises: —a side assembly (2) to form at least one of the lower side, or base, of the frame structure (1), or the upper side, or cross bar, of the frame structure (1), or a mount, or column member arranged between the base and the cross bar, of the frame structure (1); —said side assembly (2) comprising—a track (3) suitable to firmly connect to the ceiling or the floor or a support structure, said track (3) having body extending along a preset first longitudinal extent (X-X); —said assembly further comprising a telescopic section bar (4), suitable to be connected to said track (3); —said telescopic section bar (4) forming at least one invitation and coupling seat (5) and being suitable to receive a coupling section bar (6) secured to said pane (7); —said invitation and coupling seat (5) being defined by a sliding and resting wall (8) that, with an edge (9) thereof, defines a seat opening (10) through

Abstract: A plurality of carriages, each provided with a relevant mold holder press, are movable along a processing line comprising a press removal and/or replacement area. Whenever a carriage arrives in correspondence with the press removal and/or replacement area, a shuttle provided with gripping forks, comes alongside and is controlled to move in synchronism with the carriage to take out a mold holder press by lifting and removing it while the carriage is in movement; the shuttle subsequently provides to transfer, by the same system method, a new mold holder press onto the same carriage, or onto a subsequent empty carriage, in movement along the press removal and/or replacement area.

Abstract: First and second skin members for moulded articles provided with rearwardly folded connecting rims are positioned into a mould. Keeping the connecting rims side by side arranged into a cavity of the mould; a polyurethane mixture is injected and cured between the opposite rims to form a first joining bead; a second joining bead of polyurethane material is provided on the first joining bead to bridge and the connecting rims.

Abstract: A method and an apparatus for thermoforming bodies in plastic material with a mold (11). A sheet (15) of thermoformable plastic material is heated to a plasticization temperature, supporting it along its peripheral edges. The heated sheet (15) is pre-shaped to create an enrichment of material, performing a sag by relative movements for approaching, raising and/or rotating its peripheral edges, maintaining the plastic sheet (15) in a suspended condition. The pre-shaped sheet (15) is then brought into close contact with the mold (11) and vacuum-formed making it adhere to the shaping surface (12) of the mold, (11).

Abstract: A method and an apparatus for applying a cover sheet of plastic material to the surface of a mold, during the molding of panels and/or of plastic pieces. The cover sheet is pneumatically held and stretched by a support frame provided with a sheet clamping groove, which peripherally extends for at least part or the edges of the mold; the support frame is provided with an air suction chamber connected to the sheet clamping groove by at least an air suction slot which opens on the bottom of the groove. The pneumatic support frame for the cover sheet and the mold are movable between each other for pneumatically adhering the cover sheet to the edges and the internal surface of the mold.

Abstract: A pedestal with radial arms for chairs, items of furniture and the like comprising a metal core formed of a cylindrical boss to which may be attached a column capable of securing and supporting the seat or item of furniture, this boss having attached thereto one or a plurality of tubular metal arms projecting radially therefrom, with a boss cover member which can be inserted on the core having a central member and one or a plurality of radial branches corresponding to the arms of the metal core which are open at the base and extend over part of the length of the said arms, together with for each arm of the metal core a covering sheath provided with means of attachment to the end of the arm which can be inserted in a longitudinal direction on the corresponding branch of the boss cover member to a length depending on the extent of the arm.

Abstract: A support structure for office tables and desks is constituted of a cylindrical connecting element having a substantially horizontal axis, equipped with a plurality of lateral connectors, to some of which there are connected two or more pairs of inclined legs, diverging downwards at least in a vertical plane perpendicular to the axis of the connecting element. A plurality of support elements are connected to said legs and/or said tubular body for one or more working planes, projecting horizontally and transversely and/or oblique with respect to the axis of the connecting element. At the upper ends of the legs connector members can be provided to which there may be attached pairs of uprights carrying an upper plane and/or other members raised above the working plane.

Abstract: The flexible cable guide consists of a plurality of double-T shaped elements having curved flanges defining aligned cylindrical spaces, separated from one another by a central web of the shaped element, the elements being connected to each other by two-directional joints, a plurality of electrical supply, communications and the like cables being lodged in the cylindrical spaces defined by the curved flanges.

Abstract: An adjustable chair, intended in particular for office use or similar, consists of a base equipped with a telescopic column supporting a seat, preferably padded. The seat has a rigid outer frame divided into two sections hinged together about an axis, a front section of this frame being rigidly mounted on the telescopic column and the rear section being able to tilt relatively to the front section, there being an adjustable, resilient support means acting between the front and rear sections of the outer frame. The rear section of the frame supports in a pivotal manner a seat back, preferably padded, affording a tilting action by means of an adjustable, resilient means acting between the rear section of the frame and the seat back.
