Definitions

  • the invention relates to an elastic strand sealing profile for windows, doors or the like.
  • Insertable foot section, the at least one spreading from it Has holding rib for anchoring in the holding groove, the foot and head section are connected to each other via a profile back and from this a cover lip protrudes to cover the receiving groove in this inserted foot section, and wherein the head section forms a closed hollow section in cross section, in which the Part of the profile back lying on the head section of the foot section facing away, upper end via a towards the inside of the hollow cross section arched crossbar with a sealing web that repels obliquely from the profile back is connected at a distance from the junction with the crossbar as a support web enters at a distance from its freely projecting end.
  • the support web is as an im essentially rectilinear web, which is a sealing engagement exerts a relatively strong restoring force on the sealing web when the latter is closing a window or a door is pressed in the direction of the sealing back.
  • the rectilinear support web forces in the longitudinal direction when deflected, a small movement of the sealing web connected to it relative to the adjacent surface to be sealed. That leads to the appearance of a undesirable friction between the sealing web and the contacting surface as well a certain amount of wear and, in unfavorable conditions, even a Cause noise.
  • small constraining forces occur in the Contact surface between the sealing web and the counter surface to be sealed, the one Can impair the sealing effect.
  • the object of the invention is to create a generic one To improve the sealing profile so that the disadvantages mentioned are as possible largely eliminated, while at the same time over a large tolerance range a particularly good sealing effect is obtained.
  • this is done with a strand seal of the type mentioned thereby achieved that the support web in the unloaded state of the seal in Cross section has a curved shape away from the profile back and at its the End facing away from the sealing web opens into a connecting web which extends from the Junction point diagonally from the profile back towards the cover lip runs, at its other end in a running to the profile back, at Sealing engagement does not change its position relative to the intermediate web runs in and is pivotable in the direction of this upon sealing engagement.
  • the strand sealing profile according to the invention has the Support web and the connecting web connected to it and the relative Arrangement of these to one another a "soft" closing and sealing behavior, i.e. it becomes a sufficient for a satisfactory sealing effect in sealing engagement Sealing pressure is generated at the sealing lip and when the sealing gap is reduced maintained without a comparatively strong back pressure the profile is applied, which the user finds uncomfortable and "hard”.
  • This can also be explained in the seal according to the invention in that the Support web because of its arched profile away from the back of the profile during sealing engagement defined and without any difficulty bends outwards or bulges outwards, its two ends forming precisely defined kinks. Doing so Overall sealing engagement the connection between the sealing web and the intermediate web controlled buckling behavior without the undesirable Constraints occur.
  • the support web preferably runs in the unloaded state of the seal approximately vertically into the sealing web. This is advantageously achieved in that the support web via a in the crossbar curved end region runs into the connecting web.
  • the intermediate web is the cover lip itself or that the intermediate web is approximately runs vertically into the profile back and in turn with another support bar the cover lip is connected, with, again preferred, this further support web in the Intermediate web approximately in the area of the junction of the connecting web in this comes in.
  • the support web can have different shapes, although it is completely particularly preferred in the unloaded state of the seal with one of the profile back technological, arched, preferably circular arched, curved course is trained.
  • Support web runs into the end of the intermediate web facing away from the profile back. It is also possible not to use the support bridge for certain applications End, but in the area between the two ends of the intermediate web to let.
  • the cover lip is further preferably in the foot section over an oblique Stiffening web supported against the profile back. This allows one particularly stiff foot area and thus a good fit of the invention Reach the string seal in the receiving groove, while also covering the lip is better supported towards the top and thus the one that occurs during sealing engagement Force transfer via the support web and the connecting web down a reinforced Support is experienced.
  • Another preferred embodiment of the invention also consists in the fact that the Cross section of the support web arched away from the profile back not in the form of a continuous arched curvature, but by two V-shaped under one Ridge sections extending at an angle to one another are formed, in the unloaded Condition of the seal, the two web sections to the apex of the V from Converge the profile back away.
  • Fig. 1 shows the cross section of an elastic strand sealing profile 1, the one Head section 2 and a foot section 3, which together a profile back 4th train through which they are also connected.
  • the head section represents 2 the “upper” section and the foot section 3 the “lower” section of the Strand sealing profile 1.
  • the designations "top” or “top” and “bottom” or “lower” should in the following the head-side position or the head side and indicate the position on the foot side or the foot side of the sealing profile (i.e. one in the 1 to 5 "upper” or “lower” position).
  • the strand sealing profile in the receiving groove 19 is e.g. of a window sash or door sash rebate 20, as shown in FIGS. 3 to 5 is shown, which will be discussed in more detail below.
  • a lip 6 protrudes laterally, which also the Separates the head section 2 from the foot section 3 and serves the receiving groove 19 to cover the inserted foot section 3 in a sealing manner (see FIGS. 3 to 5).
  • the holding rib 5 is bent slightly upwards and by the elastic restoring force that occurs against that at its end region adjacent side surface of the receiving groove 19 pressed elastically so that it against unwanted running out of this spreads non-positively.
  • On the bottom of the Retaining rib 5 is in the embodiment shown in FIG. 1 additionally pointed protruding hooking 15 attached to the installed state (cf. FIGS. 3 to 5) additionally pulling the foot section 3 out of the receiving groove 19 counteracts and thus anchoring the foot section 3 in the receiving groove 19th reinforced.
  • the profile back 4 is in the head section 2 at its upper end via one in the direction on the cover lip 6 arched transverse web 8, the curvature of a cross section represents approximately V-shaped profile, connected to a sealing lip or a sealing web 9, the at an acute angle to the part of the Profile back 4 is set so that it is down, so towards Foot section 3, increasingly removed from the profile back 4.
  • This sealing web 9 runs not in the embodiment of the extruded sealing profile 1 shown in FIG. 1 straight, but a little curved. This favors, as shown in FIGS. 3 to 5, the sealing intervention especially in its initial phase, since it is particularly quickly a larger sealing surface (i.e. pressure surface) of the sealing web 9 on the adjusts the counter surface to be sealed. But there is also the possibility the sealing web 9, as shown in the embodiment of FIG. 2, in Form cross-section essentially straight. Which of the two designs is selected depends on the specific application or the specified one Geometry of the relationships in the sealing gap with increasing sealing intervention.
  • sealing web 9 opens at a distance A from its upper end (at which it with the crossbar 8 is connected) to the outside, i.e. towards the back of the profile, arched support web 11, whose junction is still a distance B (see FIG. 2) is removed from the lower free end of the sealing web 9.
  • arched support web 11 As from Fig. 1 can also be seen, is the arched in cross section to the outside Support web 11 at its end facing the sealing web 9 with a curved Provide end portion 10 so that it is substantially perpendicular to the sealing web 9 whose lower surface runs in.
  • the support web 11 runs with its curvature section immediately in front of the curved end region 10 at an acute tangential angle ⁇ relative to the underside of the sealing web 9.
  • the cross-sectional profile of the support web 11 is, as shown in FIGS. 1 and 2, in Cross-section arc-shaped, in particular a curvature in the form of a Circular arc section is preferred.
  • the support web 11 could, however, also be one of the Sealing back 4 arched curvature with an essentially V-shaped Have course (corresponding to the course of the upper cross section 8), the preferably from two web sections running at an angle to one another exists, the upper of these two web sections then e.g. below that in Fig. 1 angle ⁇ shown would run relative to the underside of the sealing web 9.
  • a such formation of the curvature of the support web 11 is shown in dashed lines in Fig. 2.
  • the support web 11 runs over an arcuate curve End region 12 in a connecting web 13 which (in the unloaded state of the Seal) runs at an acute angle ⁇ to the cover lip 6 and over one likewise curved end region 14 approximately perpendicularly into the upper side thereof flows into, expressly to the extent shown in Fig. 1 is referred.
  • the connecting web 13 runs from the connection or Junction with the sealing web 9 obliquely downwards from the profile back 4 away to the junction with the cover lip 6.
  • the head section 2 forms a self-contained Hollow cross section.
  • the foot section 3 also has one of the profile back 4, the Cover lip 6 and the oblique stiffening web 7 formed closed Hollow cross-section, which is a special when inserted into the receiving groove 19 forms good stiffening for the foot section 3 (cf. FIGS. 3 to 5). Since the Stiffening web 7 at approximately the same point from the underside of the cover lip 6 runs out, at the top of which the connecting web 13 opens, can Sealing engagement introduced via the connecting web 13 into the cover lip 6 supporting forces directly from below over the stiffening web 7 to the lower end of the Foot section 3 derived and supported there.
  • Fig. 2 shows another embodiment of an extruded sealing profile 1, in which the head section 2 from two superimposed closed hollow cross sections consists: the first is from the upper part of the profile back 4, the upper cross bar 8, the upper part of the sealing web 9, the support web 11, the connecting web 13 and an intermediate web 16 running essentially perpendicularly from the profile back 4 enclosed, while the other hollow cross-section from the lower in the head section 2 Part of the profile back 4, the intermediate web 16, a further support web 18 with the the intermediate web 16 approximately parallel to the profile back 4 down to the cover lip 6 is supported, and from the cover lip 6 itself.
  • the sealing profile in which the sealing web 9 is relatively far from the Cover lip 6 can be arranged, but in the case of sealing engagement the lower area of the head section 2 as a result of the hollow cross section 18 formed there remains dimensionally stable.
  • Fig. 3 shows the beginning of the sealing intervention at the time when the to be sealed Counter surface of the counterfold 21 just the sealing web 9 on the sealing back touched outside.
  • Fig. 4 shows an intermediate position in which the counter-fold 21 in comparison to the position from Fig. 3 is approximated somewhat closer to the sealing back 4 with a reduction in the gap S
  • Fig. 5 shows the end position of the sealing engagement, in which the smallest Sealing gap S D is reached and the relative position of the receiving fold 20, to which the seal 1 is attached, and the counter fold 21 is no longer changed.
  • the extruded sealing profile 1 could, however, also be designed such that in the end position of the sealing engagement, i.e. with the smallest sealing gap S D , not only the sealing web 9 rests on the upper end region of the supporting web 11, but also the connecting web 13 for abutment on the upper side of the cover lip 6 reached. Then a relatively stiff final sealing state is achieved on the sealing profile, while in the embodiment shown in FIG. 1 and shown in FIGS. 3 to 5 with sealing engagement, owing to the remaining minimum setting angle ⁇ 0 in the end position of the remaining Connecting web 13 even in the sealing end position there is a "softer" flexibility of the compressed hollow profile of the head section 2.
  • the extruded sealing profile 1 shown can be made of any suitable plastic, in particular made of a thermoplastic elastomer (TPE) or EPDM be, with the possibility also, possibly also the entire Inner area of the upper hollow profile in the head section 2 e.g. with foamed fill in elastic material, which contributes to the overall behavior of the head section Sealing engagement can be designed somewhat stiffer. It is equally understood from Even that in the foot region 3 of the extruded sealing profile 1 there are also more retaining ribs than that a holding rib 5 shown in the figures may be attached, e.g. two or three Holding ribs, which in turn are flat on their underside or with more than one Interlocking projection 15 can be provided.
