Definitions

  • the invention relates to an elastic strand seal for windows, doors or the like.
  • an upper sealing head which forms a sealing area between two surfaces to be sealed upon sealing engagement
  • a lower sealing foot which extends from the sealing head from a foot web and for holding the strand seal in a receiving groove of a sash or frame rebate of a window, a door or the like.
  • Such elastic strand seals are particularly installed in wooden windows, wooden doors or the like.
  • a corresponding receiving groove is attached in a rebate or in a frame of a window or a door, into which the elastic strand seal is inserted with the sealing foot and by means of there attached mounting devices is anchored in the receiving groove so that a tight fit of the strand seal is created in the receiving groove.
  • the object of the invention is to further develop strand seals of the type mentioned at the outset such that they can be used for at least two different groove widths of the receiving groove with only one configuration of the foot region.
  • this is achieved with a generic strand seal in that the further mounting device only comes into interlocking operative engagement with the receiving groove when the sealing foot is inserted into the receiving groove when the foot lip is bent by the receiving groove by a predetermined amount in the direction of the footbridge.
  • a foot area is used in principle, in which, in addition to a foot lip as a holding or anchoring element for a certain width of the receiving groove, a second anchoring element is arranged and designed such that it does not already have its anchoring function with the same width of the receiving groove, for which the foot lip is designed, but only with another, smaller one Width of the receiving groove, at which the foot lip is bent over by the (smaller) receiving groove by a certain, predetermined amount corresponding to the gradation of the two groove widths of the receiving groove, virtually “switches on” and only then becomes effective as a holding or anchoring element.
  • the strand seal according to the invention is thus provided with a foot region, which brings about a targeted connection of a further mounting device with a smaller groove width, as a result of which the mounting effect, which is then no longer sufficient, is correspondingly replaced or supplemented by the foot lip provided for a larger groove width.
  • the further mounting device is also designed in the form of an elastically bendable lip that spreads obliquely upward from the footbridge and parallel to the foot lip, this second lip is formed shorter than the foot lip and in such a way that it has its free end surface comes into corresponding active engagement with the side wall of the receiving groove if its width has a (smaller) groove width corresponding to the predetermined degree of bending of the foot lip.
  • Another, also preferably, configuration of the strand seal according to the invention is that the further mounting device in the form of a space on the side of the foot lip facing away from the footbridge is formed at its free end, elastically deformable projection, which particularly preferably has a sawtooth-shaped cross section.
  • the preferably sawtooth-shaped design of the cross-section of this projection proves to be very particularly favorable, but the projection can also be easily formed in other suitable cross-sectional shapes, with pointed cross-sectional shapes being particularly suitable since they result in a particularly strong supporting effect. It would even be conceivable that for certain applications to increase the supporting force, a pointed projection could in turn be provided with correspondingly smaller pointed projections on its side flanks.
  • a very particularly preferred embodiment of the strand seal according to the invention can be achieved in that, in addition to the further mounting device, additional mounting devices are provided which are designed and arranged such that they all come into hooking operative engagement with the receiving groove in succession with increasing bending of the foot lip.
  • additional mounting devices are provided which are designed and arranged such that they all come into hooking operative engagement with the receiving groove in succession with increasing bending of the foot lip.
  • these additional holding devices are arranged and designed such that they then “switch on” step-wise when the foot lip is bent by an equally large amount in the direction of the footbridge, or in other words: the additional holding devices are designed and arranged in such a way that they come into active engagement with the corresponding side wall of the receiving groove in steps of the same size as the bending of the foot lip, so that the gradation in the groove width between two successively connecting mounting devices is the same size.
  • the design can be such that with each new gradation not only one, but two or even more of these additional mounting devices are switched on, so that an increasing mounting effect can be achieved with a narrowing groove width.
  • an opposite effect may also be desirable, i.e. that in the case of larger groove widths, a number of additional mounting devices are initially switched on, while as the width of the slot becomes smaller, a smaller number of additional mounting devices (in the limiting case only one) becomes effective.
  • At least one additional holding device in the form of a lip is present in the strand seal according to the invention in addition to the foot lip (as a holding element for the largest groove width) in addition to the foot lip (as a holding element for the largest groove width)
  • these different holding devices are stacked in the form of lips (different lengths)
  • Corresponding lengths are arranged so that the longest lip (i.e. the foot lip) is on top, the next long lip afterwards, etc. and the shortest lip is at the bottom.
  • the strand seal according to the invention creates the possibility, depending on its specific design, of being able to serve several or even all of the desired groove widths of the receiving groove with a single design of the base section of the seal, which significantly reduces the number of strand seals to be produced and also considerably simplifies the storage of such Seals leads, since different seal sizes no longer have to be manufactured or kept in stock for different groove widths.
  • the elastic strand seal shown in FIG. 1 has a sealing head 1 which, in the installed state of the strand seal, serves to seal two surfaces to be sealed off against one another and forms a corresponding sealing region in the sealing engagement.
  • the strand seal shown also has a sealing foot 2, which is separated from the sealing head 1 via a cover lip 3, which, in the installed state of the strand seal, has the receiving groove 15 (FIGS. 5 and 6) into which the sealing foot 2 is inserted for the hooking holding of the seal , too covered on the top.
  • the sealing foot 2 consists of a foot web 4 projecting downwards from the sealing head 1, at the lower end of which a foot lip 5 spreads out obliquely upward (ie in the direction of the sealing head).
  • the foot lip 5 is provided at its free end with a substantially flat end surface 16 which is delimited at the top and bottom by corresponding side edges.
  • a sawtooth-shaped projection 6 with a cross section is formed, the side flank of which lies towards the free end 16 of the foot lip 5 approximately is set at a right angle to the underside of the foot lip 5, while the other side flank encloses a considerably smaller, acute angle with the underside of the foot lip 5.
  • FIG. 5 shows the seal from FIG. 1 in a state installed in a receiving groove 15 of a wooden window or a wooden door for two differently large widths of the receiving groove 15.
  • Fig. 5 shows the installation of the seal in a receiving groove 15 of a larger groove width, e.g. of 5 mm, here the required interlocking or supporting effect results from the fact that when it is inserted into the receiving groove 15 somewhat elastically bent towards the foot web 4 towards the foot lip 5 with its side edge resting on the facing side wall 20 of the receiving groove 15 21 is under pressure.
  • Fig. 6 shows the same sealing strip as shown in FIG. 1 or FIG. 4, in which case the sealing foot is seated in a receiving groove 15 which has a than that shown in Fig. 4 receiving groove by the amount of a smaller width. Due to this smaller width of the receiving groove 15 in FIG. 5, the foot lip 5 is angled more towards the foot bridge 4 than in the case of the illustration in FIG. 4, as a result of which the tip 22 of the sawtooth-shaped projection 6 on the underside of the foot lip 5 is in pressure System and thus comes into active contact with the associated side surface 20 of the receiving groove 15.
  • FIG. 2 shows three further embodiments for the sealing foot 2 of an extruded seal, as shown in FIG. 1, only one section through the foot region being shown in each case.
  • FIG. 2 differs from that of FIG. 1 in that not only a projection 6, but three sawtooth-shaped projections 6, 7 and 8 are arranged on the underside of the foot lip 5, the tips of which are mutually the same dimension a as that Tip of the projection 6 are removed from the lower side edge 21 of the end surface 16 of the foot lip 5.
  • a strand seal with such a sealing foot can be used for four receiving grooves of different widths, wherein in the case of the receiving groove with the greatest width, the necessary holding effect is achieved by the pressure system of the edge 21 of the end face 16 on the associated side wall of the receiving groove.
  • the tip of the projection 6 comes in, with a receiving groove that is again smaller by the dimension a, the tip of the projection 7 and in the case of another receiving groove that is smaller by the dimension a the tip of the projection 8 System and thus active contact with the associated side wall of the receiving groove, so that a further mounting device 6 or 7 or 8 is activated step by step with a corresponding reduction in the width of the receiving groove.
  • the difference in length is such that the lower side edge of the longer foot lip 5 is a distance a further from the footbridge 4 than the lower End edge of the further holding device in the form of the other, shorter lip 9. If such a sealing foot is inserted into a wider receiving groove, the necessary holding and hooking against undesired pulling out of the groove can be achieved by appropriate active engagement with the longer foot lip 5.
  • the smaller lip 9 When used in a receiving groove with a groove width that is smaller by a, the smaller lip 9 is activated, which comes into contact with the associated side wall of the receiving groove and thus ensures sufficient retention in the groove, while the then relatively strongly bent upwards (longer ) Foot lip 5 no longer provides a sufficient retention effect.
  • FIG. 4 finally shows an embodiment for a sealing foot, in which three lips 5, 9 and 17, of different lengths, are provided, one above the other, projecting obliquely upwards from the foot web 4 and parallel to one another.
  • the longest lip is at the top, below it the second longest lip 9 is arranged, while the shortest lip 17 is at the very bottom at the end of the footbridge 4.
  • the individual projections or lips are arranged so that only the lower side edge of the end face 16 of the foot lip 5 is in operative engagement with the side wall of the receiving groove on the widest receiving groove and ensures the desired mounting.
  • the projection 10 is activated, the tip of which then also comes into contact with the side wall 20 of the receiving groove 15.
  • the projection 11 and the end surface of the tip 9 then switch in effect. This is done in that the tip of the projection 11 and the lower edge of the free end of the lip 9 come into contact with the side wall of the receiving groove approximately simultaneously.
  • the tips of the projections 12 and 13 then switch on (likewise approximately simultaneously) in terms of their effectiveness and with still further reductions in the receiving groove gradually the tip of the projection 14, the lower edge of the free end of the lip 16 and (lastly) the tip of the projection 18. This allows such a sealing foot for seven different widths, relatively small in width use stepped grooves.
  • the relative spacing between the individual lip ends or projections can also be used in any other desired gradation pattern.
