Definitions

  • the present invention has as its subject a ring for locking the cover onto a fibre cask or the like.
  • fibre casks and the like are generally provided with covers which are fixed to the upper edges of the casks themselves, by means of locking rings.
  • connection of the ends of the metal strip to the parts constituting the lever is achieved by means of a spot welding operation.
  • the closure formed will have low reliability in that it is not infrequently the case that rupture takes place in the attachment zones between the parts constituting the lever and the ends of the metal strip.
  • the object which the present invention proposes is that of eliminating the previously indicated disadvantages by providing a locking ring for fibre cask covers and the like, which can be made simply utilising mechanical operations, of considerable security and reliability.
  • a particular object of the invention is that of providing a closure ring in which all the operations for I connection between the clamping element and the metal strip, constituting the locking ring, can be considerably simplified.
  • the locking ring in question by not requiring supplementary costs such as welding, has advantages from a purely economic point of view.
  • the locking ring itself, moreover, can be easily and rapidly fitted to the various types of fibre casks and, moreover, is able to offer the widest guarantees of reliability and safety in use.
  • a locking ring for the cover of a fibre cask or the like characterised by the fact that it comprises a profile, which can be disposed in a ring, at the ends of which is connectable a clamping element; there being provided, moreover, means for coupling the said clamping element to the said profile.
  • a closure ring for locking a cover onto a cask or the like has a metal profile strip, generally indicated with the reference numeral 1, which preferably has a substantially C-shape cross-section.
  • the said profile strip 1 can be folded to assume a substantially ring-shape conformation and, at its ends, has transverse slots 2 which constitute a fitting ; element for coupling of a clamping element generally indicated with the reference numeral 3 and preferably constituted by a lever arrangement.
  • the clamping element 3 has a lever arm 4 which is articulated at one end to a small bracket 5 provided with one or more tongues 6 which can be inserted into the slots 2.
  • a connecting arm 14 which, at the other end, is articulated to a similar small bracket 5 also provided with a tongue 6 which can be connected to the slots 2 provided at the other end of the profile strip.
  • the tongues 6 can be inserted into the slots formed at the ends of the profile strip 1 and are then foldable against the strip itself in such a way as to render the connection between the profile strip 1 and the metal band securely fixed.
  • the tongues are in practice squeezed radially against the peripheral surface both of the cover and of the cask, consequently increasing the clamping and not creating forces which tend to disconnect them.
  • a projecting slot 7 which is accessible radially, which, with the lever in the clamping position, is disposed in correspondence with coincidence slots 8 which are correspondingly defined on the lever arm 4 in such a way as to allow coupling of safety elements or locking elements which further clamp the lever arms together thus guaranteeing integrity of the closure.
  • the clamping member is constituted by a small base 15 to which is pivoted the end of the lever arm 4' which is articulated at its median portion with the end of a link arm 14' articulated at its other end to a second base member 16.
  • the base members 15 and 16 are provided with projections, indicated 6' which are correspondingly defined on the slots or apertures 2' and which are insertable in a similar manner to that described hereinabove.
  • the base member 15 has lateral sides 20 which define a window 21 in which is disposable, in coincidence, a coincidence window 22 defined in correspondence with the window 21 ; on the lever arm 4' in such a way as to obtain an insertion region for locking elements, in a conceptually similar manner to that already described hereinabove.
  • Another important aspect of the invention is constituted by the fact that the folded tongues or projections are able to exert a considerable mechanical resistance in that when they are subjected to the traction force of the profile strip for closure they are radially compressed between the cover and the upper edge of the cask, without there being any possibility of their mechanical yielding.
  • the invention thus conceived, is susceptible of numerous modifications and variations, all lying within the scope of the inventive concept.
