Definitions

  • Object of this invention is to provide a set-square-shaped connecting structure, particularly suitable to realize stable right-angle connections of the ends of hollow metal sections utilized for door- and window frames, casings and the like.
  • said set-squares are composed by two angle bars, constituted each by two flat bars, arranged at 90° and inserted into the sections in superposed position relatively to one another, until they are freely positioned against the opposing internal walls of the sections.
  • the pressure-connection of the ends of the two sections is obtained by means of a screw, inserted in a hole obtained in the corner of the sections and positioned with its axis on the cutting plane of said sections.
  • Said screw engages only into the corner of the couple of bars which is superposed to the other couple.
  • the drawback creates that the screw, by operating on a flat seat of the corner of the lower angle bar, tends to cause the rotation of the flanges of the upper angle bar on those of the lower angle bar, which makes difficult the insertion of the teeth of the two flanges of the upper angle bar in the relevant eyelets obtained in the sections arranged at 90° relatively to one another, and as a consequence of this difficulty, the edges of the eyelets and the teeth for the insertion in same undergo deformations that may jeopardize the stability of the connection.
  • Object therefore of this invention is to provide a set-square connecting structure of the type composed of two superposed angle bars for the right-angle connection of hollow sections, so designed as to obviate the drawbacks shown by the known types of set-squares, with no need for particular and/or expensive changes in the shape of said angle bars.
  • Another object of this invention is to realize a set-square of the above specified type, whose structure is such as to require neither modifications nor special arrangements in the eyelets of the sections and in the hooking teeth protruding from the upper angle bar which will translate on the lower one.
  • a set-square connecting structure for the right-angle connection of the ends, cut at 45°, of hollow metal sections for door- and window frames, casings and the like utilizing a set-square composed by two flat and superposed angle bars inserted into the ends of two adjoining sections, so as to tighten said ends to one another through a tensioning screw and the hooking of teeth protruding from the set-square into eyelets or windows obtained in the outer part of the sections to be connected to one another
  • which structure comprises, according to this invention, substantially wedge-shaped means having the function of guiding and restraining said screw, interposed between the corner of the lower angle bar and the end of the tensioning screw positioned as an engagement means on the corner of the upper angle bar and operatable through a hole obtained in the corner of the right-angle joined sections, as well as plug-in hooking means obtained, in the perpendicular direction relatively to the axis of the sections, on the faces in touch with one another of the
  • said plug-in hooking means of said angle bars are constituted by at least a rib or projection obtained, in the direction perpendicular to the axis of the sections to be connected, on the flanges of the lower angle bar, and by at least a corresponding groove obtained in the adjoining face of the flanges of the angle bar subject to tensioning by means of said screw, the coupling of said ribs and the corresponding grooves being realized with a clearance to allow, during the tightening of said screw, the necessary shiftings of the angle bar towards the connection corner of the sections and the hooking of the teeth of said angle bar into the eyelets of said sections.
  • said guiding and restraining means for said tightening screw are constituted by a substantially conic element protruding from the corner of the lower angle bar and inserted into a corresponding conic hollow space obtained axially in the ends of said screw.
  • a traditional set-square for the right-angle connection of two hollow sections whose ends are cut at 45° is substantially constituted as illustrated, by way of example, in Fig.1
  • Said set-square is constituted by two components superposed to one another and realized starting from flat metal bars, bent both at right angle, so as to realize two angle bars superposable to one another.
  • the more extended angle bar, indicated by 1 has equal flanges 1a and 1b and flat opposing surfaces, while the upper angle bar, globally indicated by 2 on Fig.
  • a threaded hole is obtained, whose axis is orientated at 45° relatively to the flanges, in which a threaded dowel 4 (capstan screw or the like) whose end is flattened and rests on a similar levelled surface 4a obtained on the corner of the lower angle bar 1 (Fig. 2); said dowel 4 is inserted through a hole 5 obtained in the connection corner between the two sections 6 and 7 to be connected to one another at 90°.
  • said sections are provided with a wide opening or window 8 and 8a respectively to stably house teeth 3 and 3a of the upper angle bar 1 during the screwing of said dowel 4, as will be better clarified in the following.
  • the locking of the two sections 6 and 7 is carried out by inserting the two angle bars 1 and 2 between the ends of the sections, kept spaced out and then approached at 90°, so that angle bar 1 rests on the internal wall of section 6, as illustrated on Fig. 2, and then, by screwing dowel 5 which, being engaged with a threading obtained only in the corner of the upper angle bar 2 (Fig. 1) and heading with its end towards plane 4a of the lower angle bar, causes the upper angle bar to shift towards the right angle formed by the two sections.
  • the set-square illustrated on Fig. 1 is substantially modified, i.e. realized as illustrated on Fig.3.
  • the shape and size (according to the type of sections to be right-angle connected) of the two angle bars 1 and 2 is substantially unchanged; the improvements which allow to prevent the aforementioned drawbacks consist, first of all, in providing, instead of the levelling 4a (Fig. 2) of the corner of the lower angle bar 1, a protruding guide element 10, having substantially a truncated-cone shape, suitable to freely house a corresponding conic hollow space obtained in the end of threaded dowel 4.
  • the conic coupling reduces frictions during the tightening of the dowel, reducing at the same time the tendency to rotate of the upper angle bar relatively to the lower one.
  • a transversal rib 11-11a is obtained on the face of flanges 1a-1b of the lower angle bar, said rib being slightly bent towards the corner and suitable to remain inserted, with a slight clearance, in a corresponding groove 12 and 12a obtained in the face of flanges 2a-2b of the upper angle bar 2.
  • Said transversal ribs 11-11a may have a length equal or even shorter than the width "L" of the lower angle bar 1, while also more ribs may be provided which engage with as many grooves of the mobile angle bar 2.
