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.
  • 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.
  • the reinforcement piece that the invention proposes 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.
  • the refrigerator door has 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 the ones that are used to assemble the hinge shafts, depending on whether the door opens to the left or to the right.
  • Each one of these reinforcement pieces has two recesses for the selective coupling in only one of them, of 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 the piece is at the top or bottom of the door.
  • Figure 1. It is a bottom plan view of the reinforcement piece applicable to refrigerator doors, object of the invention.
  • Figure 2. It is a section along cutting line A-A of figure 1.
  • Figure 3. It is a top plan view of what is shown in the above cited figures.
  • Figure 4.- It is a section along the cutting line B of figure 2.
  • Figure 5.- It is a side raised view of what is shown in figure 2.
  • Figure 6. It 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 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 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 forms a perimetric wing that slightly exceeds the prismatic volume, this wing also being beveled 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.
  • This larger side surface has been referred to as number 1 and the beveled edge of the perimetric wing is referred to as number 2.
  • the reinforcement piece includes a pair of identical generally cylindric-shaped recesses (3).
  • a rotation bushing generally referred to as number 4 can be mounted in each one of them.
  • the design geometry thereof can be seen in figures 7 to 9.
  • the shaft or pin of the corresponding hinge moves.
  • either one of the recesses (3) will be used for insertion of the rotation bushing (4.)
  • Each one of the recesses (3) of the reinforcement piece has an outer cylindric piece and towards the inside they are finished in a flat manner in order to define nonrotating means of the bushing (4), upon the latter being formed by a cylindric portion (5) and another narrow one (6) with sections equivalent to those of recess (3.)
  • the cylindric portion (5) of the rotation bushing (4) is finished in 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 partion walls (11) are joined by the end corresponding to the blind base (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 and though the inside edge reaches the bottom (12) of the recess, there is a radial or side passage due to the diametric notch (8.)
  • the notch (8) is diametric so that the rotation bushing (4) can be inserted in any position.
