Definitions

  • the present invention relates to an inverted T profile for forming false ceiling support structures.
  • Structural elements for supporting false ceilings consisting of a plurality of stringers (inverted T profiles of about 3 metres in length) coupled together longitudinally by a plurality of cross-members (also of inverted T shape) which are inserted with their end in suitably slotted holes provided vertically in the webs of the stringers.
  • An object of the invention is to provide an inverted T profile which can be easily coupled to the adjacent profile but which at the same time enables simple disengagement therefrom without the use of particular equipment.
  • the inverted T profile 2 is obtained by bending, blanking and shaping a metal band to form a central web 4 which extends from an upper tube 6 and terminates lowerly in two horizontal flanges 8.
  • Each end of the central web of the profile comprises a drawn seat 10 which extends into a lip 12 which defines in the web 4 an aperture 14.
  • each end of the web extends into a substantially rectangular tab 16 having the same height as the aperture 14 and as the drawn seat 10.
  • the tab comprises a two longitudinal ridges 18 projecting from the surface on opposite sides of the lip 12 with respect to the plane of the web 4.
  • the tab comprises a mistilinear cut 20 which forms a substantially triangular elastically deformable tooth 22, with an edge 24 cut transverse to the longitudinal axis of the profile.
  • Said tooth 22 projects elastically from the surface of the tab on the same side as the drawn seat 10.
  • articulation axis of the tooth 22 relative to the tab 16 can have any orientation with exception of that transverse to the longitudinal axis of the profile.
  • the tooth 22 presents along its articulation axis a slotted hole 28 to facilitate articulation of the tooth.
  • the two teeth 22 have merely to be pressed with the fingers such as to position them substantially coplanar with the tab 16 so as not to offer any opposition to the disengagement of the adjacent profile.
  • the inverted T profile according to the invention can be engaged with the adjacent profile in a simple and comfortable manner and be disengaged therefrom using only the hands.
  • the convex portion, the lip, the tab with the ridges and the tooth pertain to a single piece formed separately and subsequently fixed to the end of the profile web by rivets.
