Definitions

  • the present invention refers to a reinforcement piece applicable to refrigerator doors, which has been conceived and developed for placement in the inside corners of refrigerator doors, to a reinforcement assembly including such a reinforcement piece, and to a refrigerator door including such a reinforcement piece.
  • the rotation axis of the hinges presently has problems of assembly since it is possible that it does not remain centered enough since the injected material offers resistance, when this rotation axis is incorporated in the door.
  • the injected material also comes out through this area as the drilled holes of the panel through which the rotation axes of the hinges protrude are not plugged up adequately.
  • a refrigerator door of the aforementioned type is disclosed in US-Patent No. 4,238,908 disclosing a front panel being first folded backwards to form the side portions and further folded to form a rear open frame whereby a plastic material closure is fitted within said frame. Openings are provided within the upper and lower portions of the door to house vertically inserted bushings secured to a horizontal hinge arm by means of a screw which is screwed through a hole in said arm into said bushing.
  • Supplementary reinforcement plates, corner pieces and washers must be provided to provide resistance against wear out of the fitting of the bushing in the door whereby, when the space between the front panel and the plastic rear cover of the door is injected with insulating material, said material passes through the slots in the corners and, if the bushing has not been installed prior to injection, it leaks through the openings provided for the bushings and may offer resistance to subsequent insertion of the bushings whilst, if the bushings have been installed prior to injecting the insulating material, due to its great pressure it may push said bushing out of its vertical centered position thereby causing problems if not rendering correct hinging impossible.
  • the reinforcement piece permits in the first place, plugging the slots of the corners for the purpose of preventing the injected material from coming through. Secondly, it also resolves the problem of guiding of the axis of the hinge,so that offcentering is not produced. It also prevents the insulating material to come out through the holes provided for said hinge shafts to come out through.
  • a refrigerator door may have four reinforcement pieces, one in each corner and incorporated at the inner surface of the metal panel, before assemblying the plastic inner portion of the door. Only two of these reinforcement pieces are used to assemble the hinge shafts, depending on whether the door opens to the left or to the right.
  • Each of these reinforcement pieces has two recesses whereby only one of both receives a rotation bushing of the shaft of the respective hinge.
  • the rotation bushing will be inserted in either recess depending on whether the door opens to the left or to the right, as well as whether it belongs to a reinforcement piece at a top or bottom corner of the door.
  • Figure 1 is a bottom plan view of the reinforcement piece applicable to refrigerator doors, object of the invention.
  • Figure 2 is a section along cutting line A-A of figure 1.
  • Figure 3 is a top plan view of what is shown in the above cited figures.
  • Figure 4 is a section along the cutting line B of figure 2.
  • Figure 5 is a side raised view of what is shown in figure 2.
  • Figure 6 is a section along cutting line C of figure 5.
  • Figures 7, 8 and 9 are respective raised views with a sectioned side raised portion with a sectioned quadrant and bottom plan, of one of the rotation bushings.
  • the reinforcement piece applicable to refrigerator doors of the invention has a general prismatic shape with a triangular base and is made of injected plastic material. Its geometry can be seen in figures 1 to 6.
  • the base of this prismatic shape is a right-angled triangle whose side surface (1) corresponding to the hypotenuse is the one that is to be parallel to the edge corresponding to the edge of the door, this edge being determined by the folded edges of the metal panel that the refrigerator door is made out of.
  • This surface (1) forms a perimetric wing (2) that slightly exceeds the prismatic volume, this wing also having a, beveled edge in order to facilitate pressure contact by the thrust that the expansion of the insulating material that is injected in the door produces, once the metal panel receives the plastic inner portion of the door.
  • the reinforcement piece includes a pair of identical generally cylinder-shaped recesses (3).
  • a rotation bushing generally referred to as number (4) can be mounted.
  • the design geometry thereof can be seen in figures 7 to 9.
  • the shaft or pin of the corresponding hinge moves.
  • the rotation bushing (4) is selectively inserted into either one of the recesses (3).
  • Each one of the recesses (3) of the reinforcement piece has a first cylindrical portion and towards the inside they are finished in a flat portion in order to define antirotation means for the bushing (4) comprising a cylindric portion (5) and another flattened one (6) with sections equivalent to those of recess (3).
  • the cylindric portion (5) of the rotation bushing (4) extends into a flange (7) and the free end of the narrow portion (6) has a diametric notch (8).
  • the recesses (3) as clearly seen in figure 2, also open towards one of the side walls (9) of the former general prismatic-triangular shape according to longitudinal grooves (10) flanked by partition walls (11).
  • the longitudinal partition walls (11) are joined by the end corresponding to the closed bottom (12) of the recess (3), while they are separated at the other end and form an opening at the bottom part of figure 2.
  • the rotation bushing (4) is introduced through the hole (4) made in the edge of the door, in correspondence with the recess (3) and though the inside edge reaches the bottom (12) of the recess, there is a radial or side passage due to a lateral notch (8).
  • the notch (8) is diametric so that the rotation bushing (4) can be inserted in any position.
