Definitions

  • the invention relates to a sealing profile, in particular for sealing the gap between a door or a lid of a refrigerator and / or freezer and its housing opening, with a foot which can be fastened to the door or the lid and an elastic sealing tube carried by the latter, the cavity of which has a rib extending between its flanks and forming an intermediate wall, the height of which is less than the clear height of the relieved sealing hose and the ridge of which approaches the opposite wall under the action of a force exerted on the sealing hose in the direction of the foot.
  • a sealing profile of the type mentioned, known from FR-A-2 048 858, is therefore provided with bellows-like flanks to increase the lifting capacity and with intermediate webs or dividing walls to increase the thermal insulation value, which are essentially perpendicular to the temperature gradient and thus ensure good thermal insulation .
  • the intermediate webs arranged in the interior of the sealing profile are designed as two opposing ribs, which press and support each other with their flanks when pressed together: these ribs, however, have the disadvantage that they severely restrict the lifting capacity of the sealing profile. This also applies to the sealing profile resulting from US-A-3 037 251, in the interior of which supports are provided.
  • the object of the present innovation is to create sealing profiles of the type described at the outset which, with the greatest lifting capacity and sufficient rigidity, have sufficient elasticity and high thermal insulation properties.
  • ribs are provided at the transition of the middle section of the sealing hose, which sits between the lateral sections and is curved outwards, to the side sections, ribs which extend radially inwards in such a way that they deform the middle section of the sealing hose Stand at least approximately vertically opposite the adjacent wall section and thus create a labyrinth-like subdivision of the cavity.
  • the lifting capacity of the sealing profile can be increased considerably with sufficient thermal insulation, whereby the sealing profile is able to reliably seal even a gap with widely differing widths. This makes it possible to allow greater deflections and twists in the doors or lids of freezers and thus to dispense with the expensive stiffening and support structures of the lid that would otherwise be required.
  • the height of the ribs is dimensioned such that when the tube is deformed below a predetermined minimum height, its ridges rest on the opposite wall, thereby increasing the further deformation of the tube To oppose resistance.
  • sealing profile has proven to be particularly favorable, in which the ribs on the ridge are equipped with means which increase their stability when they are placed on the opposite wall and prevent them from tipping over.
  • This special design creates a sealing profile that is sufficient even under the action of large forces Has lateral stability and therefore opposes the general tendency of such sealing profiles to move laterally, increased resistance.
  • a freezer designated by 10 in FIG. 1 has a housing 11, the opening 12 of which can be closed with a lid 13, which is pivotably arranged on the rear of the housing 11 with hinges 14 in the usual manner.
  • the cover 13 On its inside facing the opening 12, the cover 13 is equipped with a profile seal 15 running around its edge, which seals the gap between the edge and the frame of the housing opening 12 when the cover 13 is closed.
  • the sealing profile 15 is equipped with a foot 16 and an elastic sealing hose 17 carried by the latter, which sits on the wall of the sealing hose from the inside by means of a plurality of intermediate walls which run essentially perpendicularly between its flanks Ribs 18 and 19 is divided into several chambers 20 and 21. These correspond to each other in mirror image and are therefore labeled with the same reference numbers.
  • the sealing hose 17 is provided with a central section 22, which is located between lateral sections and bulges outward, from the transition of which to the side sections, the ribs 18 extend radially inward. These ribs 18 are opposed by a rib 19 which extends inwards from the foot 16.
  • the ribs 18 and 19 are designed in the illustrated embodiment so that they complement one another in the relaxed state of the sealing tube 17 to form a Y-shaped profile, the ribs 18 forming the arms each having an interruption 23 shortly before they strike the rib 19 . This is formed in each case by the ridges of the ribs 18 and 19.
  • the height of the ribs 18 and 19 is significantly less than the clear height of the relieved sealing hose 17, so that their ridges under the action of a force exerted on the sealing hose 17 in the direction of the foot 16, as indicated by dash-dotted lines in FIG. 2, approaches the opposite wall and thus creates a labyrinthine subdivision of the cavity of the profile seal 15.
  • the foot 16 of the sealing profile 15 is equipped on its side facing away from the sealing hose with a fastening strip 24 running along its one outer edge with a barb-like extension 25, which for fastening the foot 16 in an undercut running on the inside of the cover near its edge Groove 26 is used.
  • the lifting capacity of such a profile seal can be influenced as desired by appropriate variants in the design of the ribs and the sealing hose.
  • the stability of the ribs can be increased by shaping the ribs so that the sealing profile can only be compressed under load until the ribs rest with their burrs on the opposite wall of the sealing hose.
  • the ribs themselves are designed in sections or entirely as hollow profiles, as a result of which a considerably increased thermal insulation effect can be achieved.
