  • the covering element 16 is defined by a non-visible face 18 and a visible face 19.
  • the joint 1 In order to implement the system according to the invention and to correctly perform the assembly of a covering element 16 with a joint 1, as illustrated in figures 6 and 7 , the joint 1 must provide, if not present, a rail or track-like milling 20 along the entire length of the major dimension of the covering element 16 on its non-visible face 18.
  • the person skilled in the art will have no difficulty in recognizing the most suitable and appropriate means of performing the track-like milling 20, where this is not present on the covering elements.

  • the smaller cross-section of the upper mouth area 22 is determined by longitudinal edges 23, which contribute to confer the track-like milling 20 a shape suitable to accommodate the shaped protruding interlocking head overall indicated in 13.
  • the width of the track-like milling 20 in its upper mouth area 22 will be, with due tolerances, approximately equal to the interaxis between the long sides 14 of the head 13, the depth of the track milling 20 will be equal to the sum of the height of the pin 11 and the height of the head 13.
  • the sum of the height of the pin with the height of the joint head is less than the overall thickness of the covering element, so that the pin is only partially accommodated within the track-like seat of the covering element; preferably the pin height is between 7 and 14 mm, while the track-like seat can be between 5 and 10 mm deep.
  • the width of the track-like seat 20 is approximately equal to or greater than the largest dimension of the interlocking head 13, preferably the width of the track-like seat 20 will be 15 mm or greater.
  • the engagement between one or more interlocking heads 13 of joints 1 and the rail milling 20 enables the covering elements 16 to be stably fastened according to the invention with one or more interlocking heads 13 and thus with one or more joints 1 according to the weight, dimensions and structural requirements of the covering elements 16.
  • the joint 1 In order to correctly perform the assembly between the joint 1 and the covering element 16, the joint 1 should be placed perpendicular to the non-visible face 18 of the covering element 16 joint 1, such that the long portions 14 of the head 13 projecting from the pin 11 are aligned and parallel to the track-like milling 20. Given the dimensional relationships described above between the track-like milling 20, pin 11 and head 13, with the joint positioned perpendicular to the track-like milling 20 of the covering element 16, the head 13 will butt against the bottom of the lower area 21 of the milling.

  • Support frame 26 has generally an open C-shaped section, the correct positioning and fixing of the conventional support frame element 26 is also achieved in a conventional manner, and by way of pure example by means of at least one adjusting nut 27 which is tightened against the conventional support frame element 26.
  • both sides 28 of the supporting warping element 26 define two slots 29, which therefore run along, or close to, the free ends of the section C of the supporting frame element 26.
  • the longitudinal seats 29 are designed to house the triangular section tooth 7 provided at the free end of the arms 5 of the joint 1.
  • the inclined wall 8 and the horizontal abutment surface 9 will engage respectively on the corresponding walls 31 and 30 defined by the seats 29.
  • joint 1 is made from materials that allow elastic deformation, in particular, according to a preferred form of construction, joint 1 is made by molding polyethylene.
  • the joint 1 may be elastically snapped to any conventional supporting frame element 26 having a section of a suitable size to be housed between the arms 5 extending from the base portion 2 of the joint 1. It is also understood from the description and the drawings that the proportions between the conventional supporting frame elements and the fastening joint can vary while maintaining the proportions suitable for housing the support frame between the arms 2 of the joint, in such a way that the respective engagement surfaces 31 and 30 (for the supporting frame element) and 8 and 9 (of the joint arms) can engage in abutment ensuring a solid retention of the elastic interlocking elements snapped in their respective seats. It is in this manner achieved the scope of the invention by realizing a universal joint 1 for many and various common commercial profiles used with the support frame of coverings for ceiling and/or wall.
  • the joint according to the invention allows for the realization of a system in which, after fixing the framework to the ceiling or wall, the covering elements are fastened by a simple snap-fit operation performed without intervening with complex assembly operations between the non-visible face of the covering elements and the framework fixed in place.
  • the relative mobility of the covering elements makes it possible to carry out maintenance work on installations, such as electrical and/or computer network installations and ducts, lighting systems, etc., which may be located between the covering elements and the supporting frame, or between the supporting elements and the ceiling or wall on which the frame is installed.
