Definitions

  • the present invention refers to a joint for a refrigerator door such as refrigerating apparatus and the like, for the purpose of achieving airtightness in the closing of said door on the corresponding front of the refrigerator itself.
  • the joint has some particular characteristics of structure and shape in order to achieve optimum performance qualities in the operation for which it has been provided.
  • the object of the invention is to provide a sealing joint in order to easily replace the original joint that the door of the refrigerator includes, and that due to any circumstance has become worn or that is unserviceable, in such a way that the joint of the invention may replace the worn or unserviceable one with the required maximum guarantee and effectiveness.
  • Another object of the invention is to provide a new joint that is prevented from overturning by the force that has to be made when the door of the refrigerator is closed and opened, as well as to achieve greater resistance for the separation of the joint in its connection to the door.
  • joints that doors for refrigerators include, in order to achieve the airtightness in the closing of refrigerators, in such a way that in all cases the joint includes an outside part with a perimetric housing in which some magnetic strips are arranged, strips which keep the door closed by traction between them and some metallic pieces provided for this purpose in the front of the refrigerator, in such a way that the part supporting the magnetic strips, called the head, is complemented with another part functioning as the base and through which the fastening of the joint to the door is carried out.
  • the fastening is done in any case by the material itself that constitutes the foam as the inside insulating component of the door, said base of the joint having for this purpose a housing wherein the foam enters in order to retain the joint so that it will not be able to separate from the door.
  • the base of the joint has a special shape in which the spare joint can be coupled after replacing the rest of the joint, in other words, the part supporting the magnetic strips.
  • European patent 0713067 A2 describes an airtight joint for refrigerator doors, whose fastening to the door is done by means of gluing of the base of the joint after removal of the original joint, although the type of joint described in this patent has problems of effectiveness and use. Consequently, it has not been marketed.
  • U.S.-American patent 5,309,680 which discloses a sealing joint according to the preamble of claim 1 discloses a magnetic seal for releasably sealing two a magnetic seal for releasably sealing two doors arranged side by side on a thermally insulated cabinet, such as a refrigerator or a freezer.
  • a retainer gasket is affixed to the inner edge of each door.
  • One of the retainer gaskets encloses a magnet and retains the magnet fixed in place relative to the door.
  • Another retainer gasket is affixed to the other door and is formed of a base, a sleeve enclosing a second magnet, and two flexible webs connecting the sleeve to the base.
  • the object of the invention is a sealing joint according to claim 1.
  • the sealing joint object of the invention has as a first novel characteristic the fact that the base of the joint in question is materialized by a rear fastening plate with a fastening surface shaped in a smooth and preferably flat manner in the most part, in such a way that the base or fastening base is connected to the corresponding head supporting the magnetic strips, by means of some connecting walls displaced backward from the side edges of the fastening plate itself, on the side of the head of the joint.
  • the fastening plate is provided, on the side of the head, with a reinforcing wall with a shape similar to that of a vault, with respect to its cross section, and whose reinforcing wall is connected to the fastening plate in a manner displaced backward from the side edges of the plate, through whose reinforcing wall the connecting walls are connected to the fastening plate.
  • the cited connecting walls have approximately the same length and are connected to the reinforcing wall in the near area corresponding to the connection of said reinforcing wall with the fastening plate.
  • One of the cited connecting walls specifically the one directed towards the free end of the inside covering, has a section whose thickness is reinforced.
  • the reinforcing wall rests against the fastening plate with a reinforcing wall located inside the inside space delimited by said reinforcing wall and the fastening plate itself.
  • the fastening plate may be equipped in its section directed towards the free edge of the inside covering with a covering strip.
  • the fastening of the described joint to the corresponding refrigerator door will be done by any conventional system, such as adhesive, glue, and even a double surface band.
  • this joint complies with two basic functions in a totally effective manner, one of these functions consisting of the joint not overturning due to the force produced in the closing and opening of the door, and a second function consisting of the joint in question not gripping laterally to the glued area, but rather it causes a distribution of the pulling force through the vault shape and the inside reinforcing wall, giving rise to the forces being distributed on the part of the surface of the base or fastening plate, thus pulling by the area of the ends of the arch of the glued area, thus achieving that the glued connection offers greater resistance against separation.
  • the sealing joint applicable to refrigerator doors comprises two well differentiated parts, although they define a monobloc body.
  • One of the parts generally referred to as number (1) and corresponding to the outside part of the joint, constitutes a head with a housing (2) for magnetic strips, while the other part, considered as internal and referred to as number (3), carries out the function of a base, by means of which the corresponding refrigerator door (5) will be fastened, the airtight closing being carried out by the pressed support of the part or head (1) of the joint on the front of the body of the refrigerator in question.
  • the constituent part of the base is materialized by a fastening plate (6), with its bottom surface smooth, which may or may not be flat and provided with a layer of adhesive, by means of which precisely the fastening on the respective surface of the door (5) is carried out, thus permitting replacement of the original joint by the cited sealing joint, with total ease, since it suffices to remove the original joint and put the cited sealing joint in its place, fastening it in the described manner.
  • connection between the fastening plate (6) corresponding to the base (3) and the head (1) of the joint is done by means of a pair of connecting walls (4) and (4'), which are projected in a diverging manner from a vault-shaped reinforcing wall (8), connected by its ends to the fastening plate (6), close to the edges of this fastening plate.
  • walls (4) and (4') that constitute the connecting means between the fastening plate (6) and the head (1) of the joint emerge from the reinforcing wall (8) close to the connection of reinforcing wall with said fastening plate (6).
  • the connecting wall (4') has a section considerably thicker than the opposite wall (4), the wall (4') with a thickened section being oriented towards the free end of the inside covering.
  • the fastening plate (6) in correspondence with its inside edge, has an extension or covering strip (10), with a special shape, in order to seal the hollow (11) of the door itself, defining an element with optical closing functions to prevent movements from being produced.
