Definitions

  • a composite section for refrigerator frames is provided with two members, one of which is anchored in the mass of heat insulating material and the other is detachably connected to the first-mentioned member so as to leave between the two members a plurality of cavities or spaces in which cables, tubes and the like can be housed.
  • This invention relates to composite grooved section for refrigerator frames.
  • thermal insulation is formed by means of a layer of polyurethane foam injected directly and caused to expand in the interspace defined between the refrigerator housing and the internal cell.
  • section of the invention which comprises two members which can be coupled by in-fitting in a detachable manner, with a first of said members being anchored by way of hooklike parts into the mass of expanded polyurethane and the second of said members being secured to the first by flexible snap-in elements, the union of said two members providing a plurality of cavities inside the composite section, forming seats for electric cables, tubes and the like.
  • FIG. 1 is a detailed transversal sectional view of the composite section according to the present invention.
  • FIG. 2 is another view analogous with FIG. 1 of the section according to the invention.
  • the composite grooved section of the present invention comprises two members and 11, the first (10), of which separates the cell from the external housing and the second (11) of which engages with the part 10, defining and enclosing therewith the various cavities provided as seats and for the passage of various refrigerator components.
  • the member 10 is anchored into a mass of expanded polyurethane 12 by means of two angle parts 13, while the member 11 is secured to the member 10 by means of a flexible molding l4 defining a male connector which is snap inserted into a seat 15 formed in the member 10 defining a female connector and which extends over the whole of the front perimeter of the housing.
  • the seat 15 is shaped so as to be able to receive a metallic reinforcement 16 for securing a door catch 17 of the door lock. Further, the seat 15 allows the insertion of an electrical heating resistance 18 (in the manner shown in FIG. 2) for defrosting a magnetic seal 19 which is arranged inside a suitable slot formed in the member 11.
  • a tube 22 for the return of refrigerant fluid from the evaporator to the compressor may also be caused to pass through the member 10 such that the tube is protected and covered by the member I 1.
  • FIG. 2 in particular, in which corresponding parts have the same reference numerals as FIG. 1, an embodiment IS shown in which a chamber 20 serves as a housing for a pushbutton switch 21.
  • the chamber 20 in FIG. 1 serves as the housing for the catch 17 of the lock.
  • a composite section therefor including a first member having at least two spaced-parallel walls with one end of each wall being bent at substantially right angles to the wall to constitute means for anchoring the first member in the polyurethane, said member having another wall extending transversely with respect to and joined with said two spaced-parallel walls in spaced relationship to said bent ends and abutting the polyurethane mass, one further wall parallel to said transversely extending wall joined to the other ends of said two spaced-parallel walls providing internal cavities within the first member, a second member cooperable with the first member, said second member having a wall parallel to said one further wall of the first member and a second wall joined therewith and extending at right angles thereto for engaging one end of said another wall of the first member, said parallel wall of the second member having a flexible male connector for insertion into a seat provided in said one further wall of the first member to
