Definitions

  • Load-bearing structures are known, particularly for making display assemblies and booths, structures and shelves for stores or warehouses or partition structures, such as in offices or residential buildings, or movable wheeled assemblies. These structures may be assembled to a fixed configuration and be easily assembled, dismantled and reassembled from their individual parts and adapted to be equipped with furniture, partition elements, storage and display hardware, devices such as feet and bases, possibly of adjustable type, equipment for wall- or ceiling-mounted installation, coupling, fixation of panels or plates and the like.
  • Sections, elements and junction systems as mentioned above are disclosed, for instance, in DE 29821204, DE 29818474, DE 29912201, DE 202004011392; when these prior art systems use junction elements with screws or screwdriver- or wrench-driven coupling and fixation elements, they require processing of at least one of the sections to be jointed to enlarge at least one of the outer grooves of the section to access the screw or the operating member of the junction device, the screw or operating member being usually oriented with its axis transverse to the longitudinal axis of the section and the groove of the section. Besides being unpleasant to the view, such enlargement of the outer longitudinal grooves require accuracy and precision during machining or assembly, possibly with the use of special equipment.
  • the invention has the object of providing a system for assembling structures as described above using multipurpose junction elements that do not require machining of the grooves of the sections to be jointed, and also allow the use of sections having no outer grooves, which grooves are replaced, in this case, by corresponding inner longitudinal channels , that are designed to be milled at the ends of the sections only or at the junction areas for access to the screws in the junction element or the fitted anchor elements.
  • the invention suggests the use of sections obtained, for instance, by extrusion, which may have a variety of outer cross-sectional shapes, such as oval or drop shapes , said sections having an inner core formed of various open or closed longitudinal channels for receiving in a known manner well-known fasteners that are driven in by screwing, press-fitting or hammering such as screws , rivets , nails with or without plugs , and outer grooves like in prior art, for receiving longitudinally driven anchor screws , nuts , bushings , plates having at least one threaded hole, which are designed to be displaced along said grooves, and held therein against axial removal and, in the case of nuts and elements with a threaded hole, locked against rotation.
  • these open grooves may be wholly or partially replaced by closed channels in a corresponding internal position within the outer wall of the section, and in this case the outer wall is milled or punched, level with these channels, near the ends of the sections and/or in the positions in which screws, nuts, bushings, plates or other fastening, anchor or junction elements are required to be driven in, to obtain in that position an open groove that acts as a housing for the fastening, anchor or junction elements, and for a wrench or a screwdriver to access said elements which are oriented, in the case of screws , nails or rivets , with their axis coaxial with said groove or channel and, in the case of anchor nuts, bushings or plates, with the threaded holes oriented with their axis transverse to the longitudinal extension of the groove or channel .
  • the screws designed to be tightened within the grooves or the inner longitudinal channels of the sections may be self- tapping screws or, if holes have been previously tapped, screws having, for instance, a metric thread.
  • the invention suggests the use of a simple plate having holes formed therein, which plate may have either two parallel flat surfaces or one flat surface and one opposite surface that is designed to laterally lie on a non-flat, e.g. convex surface, of a section, of corner elements.
  • the junction plate may be also equipped with tabs projecting out of the outline of the corresponding section, the tabs having holes therein, allowing them to be fastened by screws, e.g. self-tapping screws.
  • the junction elements may also have a wall adapted to retain the end of the corresponding section, thereby peripherally covering the end portion of the section, or projections adapted to be fitted by their front sides into the inner cavities of the section, for secure fixation, possibly using a single fastening screw, e.g. at the center.
  • These junction elements essentially have one central hole and possibly two holes preferably disposed on the same axis of symmetry and/or also on a second axis of symmetry of the plate, and holes formed in an area proximate to the periphery for the passage of screws that are driven in through the grooves of the section or the milled portions at the inner channels of the section.
  • the junction system is essentially based on the arrangement that the junction element is fastened to the end of one of the sections first by fasteners such as screws, rivets, nails with or without plugs, with the shanks passing through the holes at the center and immediately afterwards by other fasteners, such as screws, rivets or nails with the shanks passing through the holes at the periphery of the junction element and longitudinally introduced into the open grooves, or the closed or open channels formed by milling or punching at the requested areas of the first section and tightened into threaded holes formed in a corresponding position, such as a connector element, a nut, a bushing or a stud within a groove of the second section, oriented for instance at 90° to the former, or, if self-tapping screws are used, into specially formed holes.
  • fasteners such as screws, rivets, nails with or without plugs
  • other fasteners such as screws, rivets or nails with the shanks passing through the holes at the periphery of the junction element and longitudinally introduced
  • the connector elements may be of various types, e.g. of angular type, at right angle or with different angles, for T, V, Y or X junctions: these connector elements may have threaded or unthreaded holes or bushings or plugs possibly of different materials that are held within respective seats to act as anchor elements. If the junction element is secured, for instance, by a single central self-tapping screw, it will be convenient to use junction elements with outer walls enclosing the outer surface of the end of the corresponding section or with projections designed to be fitted by their front sides into the cavities at the end of the section.
  • the invention suggests of equipping the junction elements with perforated tabs projecting out of the outline of the section against which they are fixed, for fixation to occur by screws passing through the holes of these tabs.
  • junctions may be obtained using simple, easily manufactured and low cost elements, without requiring any machining of the grooves on the sections , or using sections with no outer grooves , in which case machining is required at the junction points only.

  • the sections 1 may be of various shapes and essentially have an inner area consisting of at least one longitudinal groove or channel Id for receiving screwed, press-fitted or hammered fasteners, such as screws rivets or nails with or without plugs , and an inner area away from the center, with one or more longitudinal grooves or channels Ie for receiving any additional fasteners, such as self-tapping screws 9.
  • the sections 1 have at least one open Ia outer groove Ib of known type, for receiving captive anchor elements such as nuts , bushings 8a, plates 8b or elements having at least one threaded hole, which are retained by the geometry of the groove against any rotation but are capable of displacement in the longitudinal direction thereof.

  • the open Ia grooves Ib, or channels, which have been milled or punched at appropriate areas for access thereto from the outside, may be utilized as is known for receiving a variety of known elements and fittings, so that the structure composed of sections 1 may be equipped with various elements, such as hooks, supports, panels, elements for coupling or fastening, for instance brackets and/or supports, etc.
