Definitions

  • the invention relates to a closure seal according to the preamble of claim 1.
  • an angular, frame-like sealing strip is formed in one piece, it being composed of several straight strip sections which are mitred in the corner region.
  • metallic angles are used in the sealing profile, which are provided with hooks and which can be fastened in the corners in corresponding openings, for example the oven muffle flange, by hooking them in.
  • After hanging the sealing strip is mechanically pre-stressed (DE-OS 30 47 380, 32 00 642).
  • Such a closure seal is very easy to assemble and replace and results in a largely optimal seal between the closure parts, for example between the oven housing and the oven door.
  • sealing strips from several together e.g. sealing sections connected by gluing or vulcanizing and their connection to fastening parts are relatively complex, in particular when different sealing sizes or sealing types are required.
  • the sealing profile has an L-shaped cross section with a horizontal incision in the free leg of the foot part, this resulting as a straight profile strand sealing profile in the corner areas to be sealed with the above-mentioned incision in punched and bent sheet metal incisions of the oven door or the muffle frame.
  • the incisions are approximately quarter-circle-shaped.
  • the invention has for its object to provide a closure seal of the type mentioned in the preamble of claim 1 in such a way that its manufacture is simplified and in particular an essential and complex processing of the closure parts does not have to take place.
  • each support element is in the manner of an arcuate rail with an L-shaped or U-shaped, formed the sealing strip in part encompassing profile, each support element preferably having at least one fastening element, preferably a fastening element arranged in the center of gravity of the support element, with which it can be fastened to one of the closure parts.
  • the support element is hung in a simple manner, for example loosely, into the corresponding closure part in corresponding openings and is braced with this closure part when the sealing strip is placed on it. This eliminates any fastening parts arranged on the sealing strip itself. The tensile forces exerted by the sealing strip on the support element automatically fix the support element in a predetermined, correct position.
  • the design of the support element itself is very simple and production-friendly, especially when the fastening element of the support element is designed as a claw-like angled fastening hook which can be inserted and hooked into a hanging opening in the closure part, preferably in the front flange of the closure opening.
  • the measures according to claim 5 prevent the support element from falling out with certainty, since under the tensile force of the elastic seal, the angled fastening hook is supported on the closure part, which serves as an abutment for the support element.
  • the suspension opening is preferably designed as a passage and has a continuous web at a distance behind the suspension opening, which web serves as an abutment for the fastening hook.
  • a closure seal of the type according to the invention can be designed in the form of a circumferential, closed frame or, in particular when used for ovens, can be provided with at least one open frame side.
  • hooks are arranged on the free ends of the sealing strip, for example by inserting and gluing in the hollow sealing profile, with which hooking tabs the ends of the strip are in corresponding openings can be locked with pre-tension on the closure part.
  • the two free ends of the sealing strip are connected to one another via connecting straps. again the connecting tab can be glued in the cavity of the sealing profile.
  • a front flange 1 for example of a household baking oven, is shown schematically, which represents a stationary closure part and moves a closure opening 2.
  • a hinged or sliding oven door (not shown) serves as a movable closure part, which comes to rest on the front flange 1 with its peripheral inner surface in the closed position.
  • a closure seal made of elastomeric material is arranged on the front flange 1 in the exemplary embodiment. This sealing gasket is provided to prevent the undesirable escaping of the fumes arising during operation of the oven or the associated heat losses from the interior of the oven.
  • closure seal 3 is attached to the front flange 1, for example of the oven, by means of support elements 4, which are attached in the corner region of the rectangular closure opening 2 on the front flange 1 in the manner described below and on which support elements 4 the one-piece, homogeneous roll material is formed Sealing strip 5 is placed and braced with the free ends.
  • Figure 7 shows as an individual part a single support element 4 and a part of the sealing strip 5 stretched over it.
  • the sealing strip 5 has a base profile 51 with a rectangular cavity 52 which runs through the entire sealing strip 5, a wall of the Base profile 51 is slightly convex. Support knobs 53 are formed on the opposite wall of the base profile.
  • a sealing lip 54 which projects outwards and also extends along the entire sealing strip 5 on the one hand and a further, smaller sealing lip 55 on the other hand is molded.
  • the metallic support element 4 is designed in the form of an arcuate rail and has, in the region of its center of gravity, a claw-like angled fastening hook 41 which can be suspended in a hanging opening 9 in the corner region of the front flange 1, the fastening hook 41 countering the direction of the onto the supporting element 4 the aforementioned sealing strip 5 acting tensile force in the form of the resulting tensile force R, formed by the individual tensile forces Z which occur on the sealing strip 5, is angled and is pressed by this tensile force R against the back of the front flange 1 in the direction of the arrow, the front flange 1 being the fastening hook 41 serves as an abutment.
  • each support element 4 serves one of the boundary edges 10 of the hanging opening 9.
  • An arc-shaped arrow in Fig. 6 shows that a prestressing sealing strip 5 exerts a tilting moment on each support element 4, through which the aforementioned support and locking of the support element 4 is done.
  • Shaped to the free ends of each support element 4 are retaining tabs 42 which, together with the curved rail part 43, form an L-shape.
  • the support elements 4 are first loosely suspended in the corner regions of the front flange 1.
  • Each suspension opening 9 is advantageously designed as a passage and, as shown in FIGS.
  • the sealing strip 5 with its base profile 51 is inserted into the cavity of each support element 4 formed between the front flange 1 and the rail part 43 and then braced in the manner described.
  • the sealing lip 55 lies close to the front flange 1.
  • the sealing strip 5 is held and shaped in an arc shape with a relatively large radius by the holding tabs 42 and by the fastening hook 41.
  • the sealing lip 54 projects steeply above each support element 4.
  • This sealing lip 54 is pressed together when the closure is closed, for example when the oven door is closed, and is pressed more or less against the outer surface of the rail part 43 of the support elements 4.
  • a single fastening hook instead of a single fastening hook, several fastening elements can also be provided on the support element.
  • support elements 4 ′ which are in the form of arc-shaped rails, are again provided in the corner regions to support the sealing strip 5.
  • each of these support elements 4 1 has two fastening elements 41 and 41 'which are spaced apart from one another.
  • the fastening element 41 corresponds exactly to the fastening element, for example according to FIG. 6. That is, this fastening element 41 is only loosely connected to the closure part 1, for example the oven flange.
  • the other fastening element 41 ' is designed in the form of a knife-like plug-in attachment with a resilient barb 41'a and the fastening opening 9 1 provided for this purpose in the closure part 1 is only slightly larger than the cross section of this fastening element 41'.
  • this fastening element 41 ' is inserted into the fastening opening 9 1 in a positive and non-positive manner until the barb 41'a is hooked resiliently behind the fastening opening 9' on the closure part 1.
  • the assembly of the sealing strip 5 is very much easier; it only needs to be pulled over the outer profile of the support element 4 ', with which its base profile 51 automatically engages behind the rail part 43, after which the sealing strip is in the correct position. It is no longer necessary to hold the support element 4 'during the installation of the sealing strip 5.
