Definitions

  • the present invention relates to a sealing cap for radiator elements .
  • the present invention relates to a cap that is applied to an end of radiator elements for hermetically sealing the end and/or for allowing the assembly of vents, heat adjustment valves, further connections for a water inlet or outlet and the like, on the end.
  • Sealing caps are known in the art, for example obtained by moulding, which are directly screwed on the threaded end of the radiator element. Such caps are hexagonal shaped for allowing locking thereof by a wrench. They are made of metal and are coated prior to being assembled on the radiator.
  • Prior art solutions exhibit several disadvantages .
  • they exhibit aesthetic shapes, typically hexagonal, limited by the need of being gripped by a wrench; moreover, after being tightened by wrench, the caps often lose their coating in several points. In fact, the coat is removed at the points of contact with the wrench, generating totally unacceptable aesthetic imperfections.
  • the cap coating following the assembly thereof is sometimes carried out for preventing such disadvantages, but such operation is complex to be carried out and often leads to coating inaccuracies as well as to the cap gluing on the relevant end.
  • the problem of the present invention is to provide a cap for radiator elements which should solve the disadvantages mentioned with reference to the prior art.
  • figure 1 shows a perspective view of a cap according to an embodiment of the present invention
  • figure 2 shows a perspective view of the cap of figure 1 from a different angle
  • figure 3 shows a section view of the cap of figure 1;
  • figure 4 shows a perspective view of an element of the cap of figure 1;
  • figure 5 shows a perspective view of the element of figure 4 according to a different angle
  • figure 6 shows a section view of the element of figure 4 ;
  • figure 7 shows a front view of a further element of the cap of figure 1;
  • figure 8 shows a section view of the element of ⁇ figure 7, along line VIII-VIII of figure 7;
  • figures 9 and 10 show perspective views of the cap of figure 1, provided with a cover made according to different embodiments.
  • reference numeral 4 globally denotes a cap for radiator elements, suitable for being hermetically associated to an end of a radiator element.
  • cap 4 exhibits a prevailing direction X, which in an assembled configuration on the end of the radiator element is coincident with the symmetry axis of the latter.
  • cap 4 comprises a bush 8 suitable for being screwed on said end by an outer thread
  • the cap comprises closing means 16 associated to bush 8 and suitable for allowing the tightening of the bush on the end.
  • the closing means 16 comprises a collar 20 suitable for making a stop for the cap introduction into the end; in other words, collar 20 has a larger diameter than that of bush 8 so that following the screwing of bush 8 into the end, the collar makes a stop to the introduction of the cap itself .
  • collar 20 comprises gripping elements 24 suitable for allowing gripping and screwing cap 4 on the end; preferably, the gripping elements 24 are arranged on collar 20 opposite the associable bush 8.
  • the gripping elements 24 comprise at least one projection 28 suitable for allowing the rotation of cap 4. For example, projections 28 project from the collar parallel to the prevailing direction X and opposite bush 8, that is, opposite the end of the radiator element .
  • projections 28 are arranged on an outer diameter of collar 20 and have a circle arc pattern relative to a plane perpendicular to the prevailing direction.
  • projections 28 are arranged along an outer circumference of the collar relative to the bush, so as to facilitate the tightening operation of cap 4 on the end.
  • the gripping elements 24 comprise at least two projections 28 arranged in diametrically opposite positions relative to each other and preferably the gripping elements 24 comprise two pairs of projections 28 diametrically opposite to each other .
  • Two consecutive projections 28 determine windows 32 suitable for seating a tool, for example a pipe, for tightening cap 4.
  • collar 20 comprises a seat 36, suitable for allowing a snap-wise connection with an associable cover 37, for covering cap 4.
  • Cover 37 may have various shapes, preferably it is axial-symmetrical and has a cap-wise pattern.
  • Cover 37 comprises a side portion 38, suitable for surrounding and laterally covering collar 20 and projections 28, and a head portion 39 that axially covers cap 4.
  • the side portion 38 exhibits an edge 38', suitable for making a snap-wise connection with seat 36 of collar 20.
  • Collar 20 comprises a recess 40 facing the associable bush 8, said recess 40 being suitable for favouring the centring of bush 8 relative to collar 20.
  • Recess 40 preferably has a toroidal pattern, that is, it is axial-symmetrical relative to the prevailing direction X.
  • recess 40 comprises a circumferential chamfer 44, suitable for facilitating the making of a welding bead 48 between collar 20 and bush 8.
  • Recess 40 of collar 20 comprises a circular seat 52 suitable for seating at least partly a sealing element between cap 4 and the radiator end, for ensuring the fluid seal between cap 4 and the end.
  • the circular seat 52 is preferably concentric with chamfer 44 and with the prevailing direction X.
  • the sealing element for example 98 is an o-ring type seal of polymeric material, or a flat seal, shaped as a disc.
  • collar 20 is associated to a reduction unit, for example shaped as a cup 60, preferably arranged coaxially to the bush itself.
  • Cup 60 comprises a ring 64 having an outer diameter substantially equal to the inner diameter of the bush so as to be inserted at least partly inside bush 8, making a guide for positioning and fixing bush 8.
  • cup 60 comprises an inner thread 68 for allowing for example the connection of a venting valve or also for allowing the connection with further delivery pipes or other radiator elements .
  • cover 37 is provided with a central hole 70 suitable for allowing the passage of a portion of the valve or pipe, covering the remaining portion of cap 4.
  • the cap is substantially made in two portions, that is, bush 8 and collar 20 are made separately, starting from sheet according to a series of shearing operations. [0042] The two portions are then made integral preferably by welding. Preferably, collar 20 and bush 8 are attached by welding, placing an axial end of bush 8 close to chamfer 44 of collar 20, so that bush 8 and collar 20 are substantially coaxial to each other. [0043] The coaxiality is further ensured by the geometrical connection between ring 64 that fits into the inner diameter of bush 8.
  • Cap 4 is centred and screwed on the relevant end of radiator element.
  • the first screwing step can also be carried out manually by the operator, then once the travel end has been reached in the fitting of cap 4, it is possible to proceed with the sealed tightening of cap 4, using for example a pipe inserted between two diametrically opposite projections 28; in other words, the pipe or tool may be inserted in two diametrically opposite windows 32, so as to lever on the side edge of projections 28.
  • pliers and wrenches of various types.
  • an accessory is screwed on the inner thread 68 of the reduction unit or cup 60, such as a venting valve for the radiator.
  • an accessory is screwed on the inner thread 68 of the reduction unit or cup 60, such as a venting valve for the radiator.
  • the tightening collar 20 is closed or covered by the insertion, preferably snap-wise between seat 36 and edge 38' of the cover, of cover 37 on collar 20.
  • a cover 37 provided with central hole 70 is advantageously used for allowing the passing of the accessory itself through the head portion 39 of cover 37.
  • the cap for radiator elements allows overcoming the disadvantages of the prior art.
  • the cap may be associated and tightened on the radiator element end with any kind of tool without having to be careful not to damage the coating of the same.
  • a pipe element inserted between two diametrically opposite projections may be used as a tool.
  • covers of any shape may be made and envisaged, which are connected preferably snap-wise to the collar without having any cap tightening function.
  • the cap according to the present invention allows connecting venting valves or connecting pipes to the radiator element end without having to release the cap from the relevant end.
