Definitions

  • This invention relates to a door for a refrigerator, freezer or the like, comprising an outer panel, an inner panel of thermoplastic material, thermal insulation material interposed between the panels, and a seal extending around the periphery of the door and comprising a resiliently flexible sealing portion and a lip which is held between a peripheral flange on the inner panel and an inwardly directed peripheral flange on the outer panel, the flange on the inner panel having in a side thereof which faces the flange on the outer panel a channel which receives a raised portion of the lop of the seal to retain the lip between the two flanges.
  • a door for a refrigerator, freezer or the like comprising an outer panel, an inner panel of thermoplastic material, thermal insulation material interposed between the panels, and a seal extending around the periphery of the door and comprising a resiliently flexible sealing portion and a lip which is held between a peripheral flange on the inner panel and an inwardly directed peripheral flange on the outer panel, the flange on the inner panel having in a side thereof which faces the flange on the outer panel a channel which receives a raised portion of the lip of the seal to retain the lip between the two flanges, wherein the lip is made of a stiffer material than the sealing portion of the seal, and the lip has slots in it at the corners of the door, and wherein the flange on the inner panel is deflexible to allow the lip to be inserted and withdrawn from between the flanges.
  • the seal can be fitted to the door simply by applying a modest pressure manually to the seal to push the lip of the seal between the flanges on the two door panels until the raised portion of the lip enters the channel in the flange on the inner door panel.
  • a modest pulling force on the seal is all that is needed to withdraw the lip from between the flanges when it is necessary to remove the seal for replacement.
  • the stiffness of the lip is sufficient to deflect the flange on the inner door panel to allow the raised portion of the lip to enter or leave respectively the channel in this flange.
  • the slots in the lip at the corners of the door further facilitate the fitting or removal of the seal.
  • German Utility Model No. 7115601 discloses a seal having a resiliently flexible sealing portion and a securing portion which is made of a stiffer material than the sealing portion.
  • a gap which exists between the free edge of the flange on the outer panel and a part of the inner panel which faces this edge is closed by an edge portion of the lip of the seal, which portion is thinner than the remainder of the lip. This prevents insulating material entering the channel in the flange on the inner door panel during the forming of the thermal insulation, which is carried out after the initial fitting of the door seal.
  • the raised portion of the lip of the seal is hollow and a part of the lip adjacent said edge portion thereof has sealing contact with the flange on the outer panel.
  • the raised portion of the lip can be readily elastically deformed when the lip is being inserted or withdrawn from between the flanges on the door panels, which further facilitates the fitting or removal of the seal.
  • the reference numeral 1 indicates an outer door panel, which is made, for example of sheet metal and which at its periphery has an inwardly directed flange 2.
  • the door also comprises an inner panel 3 which is constructed of plastics material by vacuum forming and which is formed integrally at its periphery with an outwardly directed flange 5 which extends over the flange 2 on the outer panel 1.
  • the flange 5 is of channel-like cross-section so that in its side which faces the flange 2 there is a channel 6.
  • the cross-section of the flange 5 is composed of a number of sections which are inclined relative to one another so that the channel 6 has sloping walls.
  • the flange 5 is connected to the main part of the panel 3 by a channel-shaped part 4, the bottom of which, as viewed in Figure 1, lies below the plane A-A of the flange 2 on the panel 1.
  • a gap 7 of modest width, of the order of 2 mm which allows the outer panel 1 and the inner panel 3 to be centered relative to one another before the polyurethane mixture which constitutes the thermal insulation 8 for the door is injected and then polymerised in-situ between the outer panel 1 and the inner panel 3.
  • a seal 9 which comprises a resiliently flexible sealing portion 20 for cooperation with the edge of the cabinet on which the door is to be hung, and a lip 10 which is held between the flanges 2 and 5 on the outer and inner door panels 1 and 3.
  • the sealing portion 20 of the seal comprises a compartment 21 into which a magnetic strip can be inserted for cooperation with the edge of the cabinet to hold the door closed.
  • the sealing portion 20 and the lip 10 are formed together by co-extrusion but the lip is made of a stiffer material than the sealing portion.
  • the lip 10 comprises a flat portion 12 which is clamped between the flange 2 on the outer door panel and the free edge of the flange 5 on the inner door panel.
  • Adjoining the flat portion 12 is a hollow raised portion 13 which extends along the length of the lip 10 and which has a cross-section similar to that of the flange 5 so that this raised portion has sloping walls like the channel 6 in the flange 5.
  • the raised portion 13 is received in the channel 6 to retain the lip 10 between the flanges 2 and 5 but is elastically deformable to permit withdrawal of I the lip from between the flanges when the seal is to be replaced, as will be explained later herein.
  • the edge portion 14 of the lip 10 is much softer than the rest of the lip. The result of this construction is to prevent the polyurethan during the forming of the thermal insulation 8 from entering the channel 6 in the flange 5 and the space inside the raised portion 13 of the lip 10 and possibly impeding elastic deformation of this portion of the lip.
  • a slot 21 is formed in the lip only of the seal, the slot extending preferably along a diagonal of the rectangle of the door.
