Definitions

  • the present invention relates to a strand-shaped sealing profile according to the preamble of claim 1 and a sealing system which has such a strand-shaped sealing profile.
  • the FR 1 242 975 shows a sealing profile with an anchor foot.
  • DE 94 15 923 U1 and DE 38 43 357 A1 are sealing profiles with anchor feet known, in each of which a cavity is provided.
  • the cavities in this case have different shapes or configurations, without being executed in any way, as the configuration of the cavity affects the applied impression force when pressing the corresponding sealing profile in the associated receiving groove. It has been repeatedly found that it is difficult in the assembly of strand-shaped sealing profiles in the corresponding grooves, depress the sealing profiles in the grooves, as relatively high indentation forces of about 800 to 900 N / m are required.
  • the present invention is therefore based on the object to propose a strand-shaped sealing profile in which the assembly forces are reduced when pressing the sealing profile into the associated receiving groove.
  • the strand-shaped sealing profile according to the invention has an anchor foot, with which it can be inserted into an undercut receiving groove of a profile, in particular locked, can be. Examples of such profiles are windows or doors.
  • a transition section connects, which in turn continues in a base section.
  • a cavity which is substantially closed.
  • substantially closed here means that even if there are inadvertently small openings or cracks that connect to the outside world and that arise, for example, during the manufacturing process or use, the cavity is considered to be closed.
  • the cavity has a first cavity portion having a substantially constant first clear width.
  • substantially constant clear width is intended here to mean that small deviations from a constant clear width or from a constant inner dimension of the cavity are still regarded as not affecting the constancy of the clear width. Such small deviations can be caused, for example, by tolerances in the production process, by corresponding temperature influences or deformations that may have taken place.
  • the present invention is characterized in that the cavity further comprises a second cavity portion having a, again substantially constant, second clear width, wherein the second clear width is smaller than the first clear width.
  • the cavity thus comprises two cavity sections, which in each case form a rectangle in cross section through the longitudinal extent of the sealing profile strand.
  • the first cavity section extends at least over the entire extent of the transitional section, wherein the second cavity portion is located in the region of the anchor foot. Since in this embodiment, the cavity portion with the smaller clear width in the region of the anchor foot and thus is in the region of that part of the sealing profile, which is first pressed into the receiving groove, the force required for this Eindschreibkraft can be further reduced.
  • the first cavity section is bounded in the direction away from the second cavity section by an at least substantially planar first boundary surface.
  • the second cavity section is preferably delimited in the direction away from the first cavity section by a substantially planar second limiting surface.
  • substantially plane boundary surface here means that it is preferred that the respective boundary surface is as flat as possible, whereby also slightly concave or convex surfaces or only slightly irregular surfaces are to be understood hereunder.
  • the indentation forces can be further reduced if the first cavity section with its first clearance does not pass in a kind of step into the second cavity section with its second clearance, which is smaller than the first clearance, but between these two cavity sections a third cavity portion is located, the clear width continuously or continuously passes from the first clear width into the second clear width, so that a rounded as possible transition from the first to the second cavity portion is formed.
  • the base portion has two abutment portions each extending outwardly away from each other.
  • the two base sections are each limited in the direction of the armature foot by a support surface, which in the course of the depression of the anchor foot in the receiving groove to engage in the profile or can, in which the receiving groove is located.
  • the two bearing surfaces extend in a plane, ie perpendicularly away from a median plane of the sealing profile.
  • Such sealing profiles are symmetrical in many cases in a direction perpendicular to their longitudinal extent. Consequently this central axis is also the axis of symmetry at the same time. To simplify the illustration and description below, it is assumed that the sealing profiles are symmetrical.
  • first boundary surface and the two bearing surfaces of the abutment sections lie in one plane, ie aligned with one another, ideal stress profiles can be achieved within the profile of the profile seal during the indentation of the profile seal into the receiving groove.
  • the impressions of the sealing profile is facilitated in the receiving groove and the sealing profile hereby mechanically stressed not so strong.
  • the anchor foot preferably has two latching projections which extend outwards, ie away from one another.
  • these locking projections are symmetrical to each other with respect to the plane of symmetry, which extends in the extension direction of the sealing profile strand.
  • the latching projections are each limited by a latching surface in the direction of the base portion. These two locking surfaces lie in the state in which the anchor foot is pressed into the receiving groove, on the projections of the receiving groove, which form the undercut to.
  • a certain spring action is achieved in an attempted pulling out of the sealing profile or the anchor foot from the receiving groove, which increases the necessary for the removal of the anchor foot from the receiving groove pull-out. In other words, this increases the pull-out strength, which, with a suitable design of the geometry, can achieve about 50% of the pull-out forces customary according to the prior art.
  • the two latching surfaces extend in one plane, since usually the associated surfaces on the surfaces of the receiving grooves forming the undercut are likewise designed as surfaces located in one plane. If the sealing profile according to the invention is used in receiving grooves whose respective surfaces are arranged at an angle to one another, it is advisable to design or arrange the locking surfaces of the sealing profile accordingly.
  • the two latching projections project from the transition section preferably by a length which is about 5 to 13% of the second clear width, the length being more preferably 8 to 10%, particularly preferably about 9.1%, of the second clear width.
  • the anchor foot has a projection extending away from the base section at that of its ends, which faces away from the base section.
  • the projection thus extends between the two locking projections.
  • the boundary lines of the projection are - viewed in cross section of the anchor foot - preferably straight, but may also be concave or convex, and converge towards a common tip. Of course, such a tip can also be rounded.
  • the projection in the region of its tip in the direction from the base section to the tip has a wall thickness which is about 45 to 100% of the second clear width, wherein a wall thickness in the range of about 63 to 83% is preferred and of about 73% of the second clear width is particularly preferred. In this way, a further reduction of the forces required to push the sealing profile into the receiving groove can be achieved without overly impairing the stability or shape retention of the anchor foot when impressed.
  • the indentation forces for the anchor root can be further reduced if the first clear width has a ratio to the second clear width that is in the range of about 1.5 to 2.5, in particular in the range of about 1.9 to 2.1 with a ratio of about 2.0 being particularly preferred.
  • the height of the first cavity portion has a ratio to the height of the second cavity portion that is in the range of about 2.0 to 3.0, with a range of about 2.4 to 2.6 preferred and a ratio of about 2.5 is particularly preferred.
  • the term "height" in this context means the dimension in the extension direction from the base section to the tip.
  • the height of the first or the second cavity section should in each case be measured up to the middle of the third cavity section or be defined as reaching this center ,
  • the transition section in the region of the first cavity portion has a wall thickness which is about 45 to 100%, preferably about 63 to 83%, and more preferably about 73%, of the second clear width.
  • a sealing system which on the one hand has a rope-shaped sealing profile according to the above description and on the other hand has a profile which has a receiving groove provided with an undercut for receiving the anchor foot.
  • the anchor foot has two latching projections which extend outwardly - ie away from one another.
  • each locking projection on an overall length which is smaller than half the clear width of the receiving groove at the narrowest point of the undercut.
  • the total length of the distance between the outermost end of each locking projection is understood to its end at the cavity of the anchor foot.
  • Such sealing profiles are usually produced in a strand as a continuous product, wherein the direction along the strand, the direction of extension or
  • Fig. 1 shows a first embodiment of the strand-shaped sealing profile 10 according to the invention in cross section.
  • the sealing profile 10 is subdivided into three subregions: First, an anchor foot 20, which is intended for insertion into a receiving groove 80 of a profile 90, wherein it is locked with an undercut of the receiving groove 80, which will be discussed later; second, a transition section 30, which adjoins the anchor leg 20; and thirdly, a base section 40 which adjoins the transition section 30 and which then comprises the actual sealing section not shown here.
  • the anchor foot 20 is approximately triangular with rounded corners. At its upper end, the anchor foot 20 on the left and on the right each have a rounded latching projection 22, whose upper side is bounded in each case by a latching surface 23. The lower end of the anchor foot 20 is formed by a rounded tip 27. Between the tip 27 and the locking projections 22 of the anchor foot 20 as shown in FIG Fig. 1 with straight lines. However, the connection from the rounded corners of the locking projections 22 to the rounded tip 27 may also be convex, concave or formed with a plurality of convex and / or concave portions. Above the anchor foot 20 is immediately followed by a transition section 30, which represents the connection to an overlying base portion 40.
  • the base portion 40 has here to the left and a right projecting abutment portion 42 which are each limited to the anchor foot through a support surface 44. At the top of the base portion 40, the actual seal is not shown here - often referred to as a sealing lip - connects.
  • a cavity 50 which is subdivided into three cavity sections, extends within the transition section 30 and the anchor foot 20.
  • a first cavity section 52 at the top is formed by two straight side faces 51, shown perpendicularly here, as well as a likewise straight boundary face 53, shown here above limited. The corners between the side surfaces 51 and the boundary surface 53 are rounded, but this does not necessarily have to be so. Since the two side surfaces 51 are straight, is the clear width H of the first, upper cavity portion 52 is constant or substantially constant.
  • the lower end of the cavity 50 forms a second cavity portion 54, which is delimited to the left and right by two likewise planar, vertical, side surfaces 59.
  • the lower end of the second cavity 54 is bounded by a flat second boundary surface 55.
  • the transition between the first cavity portion 52 and the second cavity portion 54 forms a third cavity portion 56 bounded by two inclined boundary surfaces 57.
  • These boundary surfaces 57 form a continuous or sliding transition between the clear width H and the clear width G of the cavity sections 52 and 54, respectively Fig. 1 rounded, which is advantageous, but not necessarily required.
  • a profile 90 is shown, in which a receiving groove 80 is provided, in which the anchor foot 20 is to be introduced.
  • the profile 90 has on its upper side two latching projections 92, which extend toward one another and are each delimited on their underside by a latching surface 94.
  • the two latching projections 92 with their latching surfaces 94 form with the underlying receiving groove 80 an undercut, which is accessible via an inlet opening 82 with a clearance D.
  • the undercut sealing profile 90 forms a sealing system with the sealing profile 10.
  • the anchor foot 20 and the transition section 30, which consists essentially only of the two wall sections 32 deforms first.
  • the two latching projections 22 and the wall portions 32 are bent inwardly, so that the cavity 50 is correspondingly reduced or narrowed.
  • the deformation takes place in the course of pushing through the armature foot 20 and its locking projections 22 through the inlet opening 82 so strong until the two locking projections 22 have completely passed through the inlet opening and then again both can move outward.
  • This deformation process can be carried out particularly efficiently if the two latching projections 22 each have only such a thickness C which is smaller than half the clear width D of the inlet opening 82.
  • the forces required to press the anchor leg 20 into the receiving groove 80 through the inlet opening 82 can be optimized if the respective dimensions are coordinated with one another.
  • this also includes the following: the second clear width G of the second cavity section 54 forms a ratio of 1: 2 relative to the first clear width H of the first cavity section 52 ,
  • the ratio of the height E of the second cavity portion 54 to the height F of the first cavity portion 52 is 1: 2.5.
  • the term "height of the first and second cavity sections respectively means the dimension from the respective second boundary surface 55 and first boundary surface 53, respectively, to the center of the third cavity section 56.
  • the cavity 50 and the first cavity section 52, respectively, in the transition section 30 delimits two wall sections 32, which has the same wall thickness I as the distance I between the (rounded) tip 27 of the anchor foot 20 and the second boundary surface 55.
  • These wall thicknesses I are preferably about 73% of the second clear width G.
  • the deformability also improved when the first boundary surface 53 of the first cavity portion 52 lie in a plane with the two bearing surfaces 44 of the contact portions 42 of the base portion 40.
  • a simple impressions of the anchor foot 20 in the receiving groove 80 without unbalanced bending of the anchor foot 20 and the transition section 30th and a uniform concern of the locking projections 22 on the latching projections 92 is thereby made possible when the two locking surfaces 23 extend in a plane, in particular extend perpendicular to the central axis.
  • Fig. 2 shows a second embodiment of the sealing profile according to the invention in cross section.
  • This second embodiment is similar in many ways to the first embodiment. The matching details are not explained again to avoid unnecessary repetition.
  • the differences from the first embodiment are as follows:
  • the cavity 50 has only the two cavity portions 52 and 54, but no intermediate cavity portion 56.
  • the transition from the first cavity portion 52 to the second cavity portion 54 in the first embodiment by the third cavity portion 56th is continuous and therefore fluid, the transition from the first cavity portion 52 to the second cavity portion 54 in the second embodiment is stepped.
  • the first cavity portion 52 extends slightly into the base portion 40 at its upper end. That is, the first boundary surface 53 is not in a plane with the two bearing surfaces 44 of the bearing portions 42 of the base portion 40.
  • the two transitions from the locking projections 22 to the rounded here also tip 27 are not straight, but they are concave, so the tip is more pronounced here.
  • Fig. 3 a third embodiment of the sealing profile according to the invention is shown. The matching details are not explained again to avoid unnecessary repetition.
  • This third embodiment differs from the first embodiment only in that the cavity 50 is disposed inversely in the armature foot 20 and the transition portion 30.
  • the second cavity portion 54 is with its clearance G above, while the first cavity portion 52 is located with its clear width H down.
  • the cavity 50 is located somewhat further from the tip 27 of the anchor foot.
  • this arrangement forms a kind of spring when it is attempted to pull the anchor base 20 out of the receiving groove 80 again through the inlet opening 82.
  • This spring effect increases the pull-out strength of the sealing profile according to the invention.
  • the coordination of the individual dimensions with one another as explained above can not only minimize the indentation forces, but can also improve the pull-out strength.
  • the sealing profile 10 With the sealing profile 10 according to the invention, it is possible to reduce the indentation forces required for pressing in the anchor foot 20 into the receiving groove 80 by 50 to 55% compared with the previously known sealing profiles. While up to now about 800 N / m of impression forces were required, according to the invention, the sealing profile is less than 400 N / m. By approximately the same factor, but by at least 25 to 35%, in this case the pull-out forces or the pull-out strength can be increased, which is very important for a permanent retention of the sealing profile in the receiving groove.
  • a sealing profile can be provided which measures approximately 4.3 mm from the armature foot-side end of the base section 40 to the tip 27, the cavity 50 having an overall height E + F of approximately 3.5 mm.
  • the locking projections 22 each have a total length C of about 1.5 mm and project about 1 ⁇ 0.4 mm outwards, and the wall thicknesses in the transition section 30 and at the top 27 are about 0.8 ⁇ 0.3 mm. Accordingly, then the clear width D of the inlet opening 82 of the receiving groove 80 of the profile 90 is about 3.2 mm.
