Definitions

  • the invention relates to a glazing gasket made of elastic plastic with a trained as a hollow profile head portion and a subsequent foot area for anchoring the glazing gasket in a retaining groove of a frame or a wing of a window, a door or the like.
  • the head and foot area via a profile back with each other are connected, the head region on its side opposite the profile back comprises an upper and a lower leg outer web which is connected at its upper end via a connecting web to the upper end of the profile back and opens at its lower end in a transverse web, the about an offset at a distance from the back of the profile in him incoming support web is connected to the profile back and continues beyond the Einmündestelle the lower leg of the outer web out, and further wherein the two legs of the outer web at density iff are mutually pivotally connected to each other, wherein in the unloaded state of the glazing gasket of running from the connecting web of the upper leg of the outer web to the lower leg from the profile back spreads at an acute angle.
  • a glazing gasket of this type is used in the DE 197 14 465 C1 described.
  • the upper leg of the outer web of the head portion serves as a sealing ridge, which is pivoted in sealing engagement of the counter surface to be sealed from its in the unloaded state from the sealing ridge spreading position in the direction of the sealing back. Leads to this pivoting that this upper leg assumes a parallel to the sealing ridge Verschwenklage, then he lies with his entire flat outer surface against the sealed counter surface, whereby the maximum sealing effect is achieved.
  • the object of the invention is to propose such a glazing gasket which exhibits a very good sealing effect over a larger tolerance range, even with relatively large gap tolerances, and at the same time better prevents the undesired penetration of moisture.
  • the glazing gasket according to the invention should also be usable with relatively low closing forces.
  • a glazing gasket of the aforementioned type characterized in that the crosspiece is an obliquely to the profile backs sealing web, with its over the junction of the lower leg of the outer web projecting web portion in sealing engagement to rest against the back of the profile back outside of the lower leg the outer web is pivotable, approximately the same length as the lower leg of the outer web is formed and with this forms an acute angle, and that the lower leg of the outer web is connected to the sealing land via an arcuately rounded intermediate portion, the tangential on its side facing away from the profile back and approximately perpendicularly enters the sealing web on its side facing the profile back, that further the two legs of the outer web are connected to each other via a gutter, which approximately at right angles from the lower end of the upper leg runs in the direction of the profile back and has a length which corresponds approximately to the outer side facing away from the profile back of the thickness of the projecting portion of the sealing web, and further that the free end of the sealing web, in the unloaded state of the glazing
  • a sealing web extending obliquely to the profile back is first inserted below the lower leg of the outer web, into which the lower leg of the outer web opens, the sections of this sealing web projecting beyond the junction of the lower leg of the outer web against the counter surface to be sealed against the sealing surface the outer side facing away from the profile back of the lower leg of the outer web is pivoted against which he finally comes to the plant.
  • This folding of the projecting sealing web against the outside of the lower leg of the outer web takes place at the beginning of the sealing engagement, wherein at this pivoting of the sealing web initially the hollow cross section of the head portion of the glazing gasket is not deformed as well.
  • the free end of the sealing web in the unloaded state of the seal, protrudes further from the profile back than also obliquely projecting from this lower end of the upper leg, during the closing process ensures that the sealed counter surface in each case first with the vorsp Schwarzenden sealing lip comes into contact and this folds first before it starts against the lower end of the upper leg and then from this point not only the latter also folded in the direction of the profile back out, but also the whole hollow profile of the head portion of the seal deformed.
  • connection of the lower leg of the outer web with the sealing web over an arcuately rounded intermediate portion which enters tangentially into the sealing web on its upper side and opens approximately vertically in this sealing web on its underside facing the profile back, creates a hinge point, the pivoting of the protruding Sealing section against the outer surface of the lower leg of the outer web favors.
  • the approximately same length of the projecting portion of the sealing web and the lower leg of the outer web also causes the sealing web in its folded against the outside of the lower leg does not collide with the lower end of the upper leg of the outer web in the folded state.
  • the configuration of the intermediate web, which connects the upper and the lower leg of the outer web with each other such that it approximately corresponds to the outside of the thickness of the protruding portion of the sealing web on its outer side, also ensures that the sealing web in the folded state and not to the outside extends beyond the position of the lower end of the upper leg of the outer web, which is favorable in the interest of training good sealing conditions.
  • the glazing gasket according to the invention has a very large tolerance pickup and at the same time a very good sealing effect, and this in conjunction with low closing forces.

  • the glazing gasket according to the invention runs at the upper end of the profile back a sealing tongue from obliquely, which projects inclined towards the rear side of the profile back facing away from the hollow profile of the head region.
  • the glazing device according to the invention also consists in that along the profile back facing inside of the upper leg of the outer web of this projecting elastic, in cross-section approximately rectangular support block is mounted, whose thickness is chosen so that in sealing engagement in the presence of a Sealing gap in nominal size, namely, when the upper leg of the outer web is tilted parallel to the profile back, between the facing surfaces of support block and profile back still no contact, but still a free gap of 2/10 mm to 3/10 mm is formed.
  • the support block consists of a suitable foamed plastic material, such as a suitable TPE (thermoplastic polyethylene). If the mounting gap of the nominal gap width, z. B.
  • the connecting web between the upper end of the outer web and the upper end of the profile back in its central extension region, in which he can bulge outwards at undersize of the mounting gap, is provided with a reduced wall thickness, so that the case be reduced forces.
  • the slope of the sealing web in the unloaded state of the glazing gasket can be done at any suitable angle, but is most preferably carried out so that it is inclined in the range of 40 ° to 50 °, more preferably at 45 °, inclined to the profile back.
  • the sealing web is formed flat on its outer side facing away from the profile back, whereby the formation of a relatively large contact surface with the counter surface to be sealed is achieved.
  • Fig. 1 Fig. 3 is a cross-section through an enlarged scale glazing gasket 1 made in the form of a strand seal made of a suitable elastic plastic, such as a SEBS (styrene-ethylene-butadiene-styrene elastomer).
  • a suitable elastic plastic such as a SEBS (styrene-ethylene-butadiene-styrene elastomer).
  • This glazing gasket 1 has an upper head area 2 and a lower foot area 3, which are connected to one another via a profile back 4.

  • the head portion 2 is formed as a hollow profile, and at the foot region 3 is z.
  • the head portion 2 of the glazing gasket 1 initially comprises a portion of the profile back 4, the head portion 2 opposite an outer web 5, which in turn has an upper leg 5A and below this a lower leg 5B.
  • the outer web 5 is connected at its upper end, ie at the upper end of the upper web 5A, via a connecting web 6 with the upper end of the profile back 4 facing away from the foot region 3.
  • the upper leg 5A and the lower leg 5B of the outer web 5 are connected via an intermediate web 12 with each other, pivotally connected to each other, which, as Fig. 1 shows at the lower end of the leg 5A protrudes approximately at right angles to this in the direction of the profile back 4 out.
  • this gutter 12 coming from below and while spreading at an acute angle from the profile back 4, the lower leg 5B opens at its upper end, the lower leg 5B simultaneously at its other, the foot area 3 facing the lower end via a hinge point in enters a sealing ridge 7 at a junction 9 from above.
  • the sealing ridge 7 extends at an acute angle y, which is preferably selected in the range of 45 ° to 50 °, relative to the profile back 4, wherein it spreads in the upward direction of this.
  • the sealing web 7, offset at a distance from the profile back 4 runs into a support web 8, which in turn opens approximately at right angles into the profile back 4.
  • the sealing ridge 7 also extends beyond the mouth 9 of the lower leg 5 B of the outer web 5 addition, as Fig. 1 shows, wherein the protruding portion of the sealing ridge 7 is denoted by 7A.
  • the sealing web 7 is formed flat in the illustrated embodiment.
  • the upper leg 5A extends, also in the unloaded state of the seal, at an acute angle ⁇ , preferably with a value of 20 ° to 25 °, obliquely to the profile back 4, wherein it towards the lower leg 5B arranged below it, thus From above, is spreadingly spread from the profile back 4, as shown in the illustration of Fig. 1 in detail shows.
  • the profile back 4 is provided at its upper end facing away from the foot region 3 with a short sealing tongue 18 which is inclined in the direction of the hollow profile of the head portion 2 opposite side of the profile back 4 and rests against the outer surface of a window 15 in the installed state, like this from the representations of Fig. 2A to Fig. 2D as well as the 3 and 4 is apparent.
  • the connecting web 6 between the upper end of the upper leg 5A and the upper end of the profile back 4 has in cross section a course of its wall thickness such that the wall thickness d is tapered in a central region of the web extension, while it increases towards the two ends.
  • This can be achieved that in an installed state in which the gap thickness to be sealed between the window 15 and the sealed counter surface 17a of the window frame 17 is slightly less than the nominal gap thickness, in the installed state, as in Fig. 3 is shown, the connecting web 6 bulge upwards, so can dodge by curvature. This ensures that not from a specific point immediately an exponentially increasing back pressure is built up.
  • Fig. 1 As seen from the cross section of Fig. 1 is further removed, is mounted on the inside of the hollow portion of the head portion 2 side of the upper leg 5A of the outer web 5 a protruding from this in the interior of the head portion 2 support block 20, which consists of an elastic material, preferably a foamed elastic plastic, and Has approximately the shape of a rectangle in cross section. He lies at its lower end side against the inner surface of the intermediate web 12, but it projects beyond in the direction of the hollow cross section of the head portion 2.
  • an elastic material preferably a foamed elastic plastic
  • an adhesive strip 19 is permanently inseparably attached to the back of the profile back 4, which with the profile back 4 z. B. may be suitably welded.
  • This adhesive strip 19 serves to secure the profile back 4 at the corresponding location at the front end surface of a window 15 to be sealed here when installing the glazing gasket 1.
  • This adhesion to the window 15 also ensures that no moisture or dirt on the outside of the window can get between them and the profile back 4 at all.
  • the support block 20 is arranged on the upper leg 5A so that it is in a fully folded state, so in contact between its inner end surface and the facing surface of the profile back 4, pretty much opposite to the profile back 4 of the arrangement of the adhesive strip 19. This can during assembly by pressing the leg 5A and pressing the support block 20 against the profile back 4 a corresponding force applied to the profile back 4 and from this on the adhesive strip 19 and thereby the adhesion of the sealing back 4 are realized on the outer surface of the window 15 during installation.
  • a suitable foamed TPE with 20 ° to 25 ° ShA be used, while for the other material of the head region 2 z. B. a hardness of 60 ° ShA can be provided.
  • the support block 20 could be attached instead of at the back of the upper leg 5A but also the profile back 4 of the head portion 2, there the position of the adhesive strip 19 opposite, so that in this case when mounting the seal of the upper Leg 5A pivoted freely and only after contact with the side facing him the support block 2 for pressing the adhesive strip 19 to the window 15 required pressure force can be applied.

  • the four FIGS. 2A to 2D illustrate a closing operation of a window 15 in a frame 17, in different closed positions:
  • Darin shows Fig. 2A the moment in which the glazing gasket 1 with its freely projecting sealing web 7 when swiveling just in contact with the sealed counter surface 17a of the frame 17 passes.
  • the head portion 2 of the glazing gasket 1 is not yet deformed, like that Fig. 2A is apparent.
  • Fig. 2B shows a slightly later closed state, in which the window 15 has reached a closed position in which the sealing ridge 7 is pivoted so far from the sealed counter surface 17a in the direction of the second leg 5B, that he just on its outer surface not (or maybe already). However, apart from the pivoting of the sealing web 7, no or almost no deformation of the head region 2 of the glazing gasket 1 has taken place.
  • Fig. 2C illustrates a somewhat later closing state, in which by a further approximation of the pivoting window sash 16 with the window 15 in the direction of the window frame 17 toward the sealing web 7 with the voltage applied to it lower leg 5 B and at the same time the upper leg 5 A in the direction of the Profile back 4 are pushed even further.
  • the sealing ridge 7 with its the window frame 17 facing outside already about as good as its whole on the Einmündesteg of the lower leg 5B projecting length 7A rests against the counter-surface 17a to be sealed.

It can be seen that over a very large contact surface, which extends from the top of the window frame 17 to the bottom of the head portion 2 of the glazing gasket 1, a sealing system is ensured.
  • the upper leg 5A of the outer web 5 and the sealing web 7 are also with their outer sides against the sealed counter surface 17a in full length, so that a very large sealing surface is given.
  • the glazing gasket 1 is installed in a sealing gap which is significantly larger than the nominal sealing gap, in the example shown z. B. has a width of 7 mm.
  • the upper connecting web 6 is not bulged, but he does not quite project from the window 15 to the facing end of the window frame 17.
  • the sealing ridge 9 runs, which in turn rests over its entire length underneath against the counter-surface 17 a to be sealed.
  • liquid may penetrate from the outside via the small wedge gap which runs between the upper region of the upper leg 5A and the counter-surface 17a to be sealed.
  • this is then held at the point at which the upper leg 5A bears against the counter-surface 17a to be sealed and is pressed, from further penetration into the gap. Should still take place penetration, the corresponding liquid is introduced into the region between the sealing lip 7 and the outer surface facing the lower leg 5B and received there, so that it can not come to an even
