Definitions

  • the invention relates to an element sealing and retaining strip made of elastic material for sealing and fixing glass panes or filling elements in surrounding frames, which are made of wood, metal or plastic, which strip has a sealing lip 1 intended to rest against the pane or the filling element 8 a thickened tip 101, provided with a support area 102 on the disk or the filling element 8, and a foot area 2 extending from a transition area 11 adjacent to the root 103 of the sealing lip 1, which foot extends essentially in the opposite direction, at least on its one Side carries anchoring lips 5, the longitudinal central axes 41 of which extend from it in a direction inclined towards the sealing lip 1, and is provided with a surface which is on the same side as the back of the sealing lip 1 facing away from the support area 102 and which directly adjoins the sealing lip 1 Transition area 11 adjacent plant area 3 forms in order to direct the pressure of the sealing lip 1 deformed from lying on the pane or the filling element 8 onto the surrounding frame 7.
  • the foot is usually provided with lips which protrude transversely from it, bend against the groove opening when inserted and therefore wedge against the groove wall when the foot is pulled out of the groove. Examples of this can be found in US Pat. No. 3,208,836, particularly in FIG. 6, and US Pat. No. 3,892,371.
  • the foot itself is thinner than the groove width, at least over part of its length, as the first-mentioned document shows. According to both documents, the foot lies against the full depth of the groove on one side wall.
  • the invention therefore aims to design the element sealing and retaining strip in such a way that a high surface pressure is achieved within the groove by reducing the contact area lying against the wall, and that the parts of the foot no longer abutting against this wall are formed by the wind forces Torque around the contact area is correctly transmitted to the lips in order to increase their contact pressure on the opposite wall.
  • the contact area 3 extends only over a small part of the height of the foot and the side of the foot 2 adjacent to it is either set back or then from it 3 in the direction of the free end of the foot 2 towards the longitudinal center line 21 of the foot 2 approaches to form the contact area as a projection for the sole transmission of the pressure mentioned.
  • the element sealing and retaining strip according to the invention it is possible to dispense with making the lips mentioned and the sealing lip lying against the pane from softer material than the remaining part of the strip, or a U-shaped border encompassing the pane at its edge with a To provide teeth in which the sealing lip of the bar engages, as shown in the prior art; Both measures only make production more expensive and also make assembly more difficult. Furthermore, thanks to its good anchoring, the strip according to the invention can also be used in grooves which have only a limited depth due to the moderate strength of the frame material (e.g. wood).
  • the frame material e.g. wood
  • the bar in its simplest embodiment according to FIG. 1 has a long, curved sealing lip 1 with a tip 101, which contains an area 102 designed as a support surface, and a root 103 at the other, much thicker end and therefore less flexible against bending.
  • the strip comprises a foot 2. This has on one side an abutment area 3 which runs approximately parallel to the longitudinal center line 21 of the foot 2, but extends over only a short area.
  • the foot 2 is provided on both sides with anchoring lips 4, 5, which initially serve to bridge the tolerance between the width of a groove 6 receiving it and the foot thickness.
  • the anchoring lips 5 perform the main function, while the anchoring lips 4 only support it. They could even be left out, but they are usually also provided. Two anchoring lips 4 and two anchoring lips 5 are customary.
  • the groove 6 is embedded in a frame 7.
  • the seal that the element sealing and retaining strip is to exert is a pressure seal, i.e. the bar must be constantly under pressure against the pane or the filler element 8 in order to press it against the frame edge (not shown) arranged on the inside of the building, in particular even if there is an interval between two gusts of wind on the outside of the building Figures on the right, for a short time a much lower pressure than inside the building, so that the pane 8 could be pushed away from the edge of the frame.
  • the latter only has parallel walls in order to be able to machine it using appropriate frame materials and thus to produce it as simply as possible. Tilted walls or even so-called undercuts, which would effectively support the aforementioned anchoring, are therefore excluded from the outset, and therefore the perfect anchoring must be achieved solely by a special shape of the element sealing and retaining strip, which will be explained below.
  • the investment area 3 is to be considered for the time being. So far, no such has been available; one only knew the anchoring lips, while the actual foot was narrower than the groove in order to be able to drive it into it with as little effort as possible.
  • the contact area 3 now protrudes laterally like a kind of shoulder or projection from the foot 2 and forms a contact surface which runs essentially parallel to the longitudinal center line 21 of the foot 2.
  • the contact area 3 is located directly adjacent to the connection area between the foot 2 and the root 103; this area forms a transition zone between the foot and the sealing lip and is designated by 11.
  • the task of the contact area 3 is now to derive the pressure forces generated by the deformation of the sealing lip abutting the disk 8 into the wall 61 of the groove 6 adjoining it.
  • the counterforce D is therefore greater than the compressive force A because the two forces are not in the same line of action.
  • a torque therefore acts on the contact area 3, formed from the force A and the distance of its line of action from the center of the contact area 3.
  • This torque now tries to tilt the bar around the relatively small contact area 3.
  • the anchoring lips 5 are pressed against the corresponding wall of the groove 6; Since their vertical distance to the contact area 3 or to its center is shorter than the distance mentioned above, the forces acting on the anchoring lips 5 are greater than A in total. They also act in the same direction as A; the counterforce D is therefore equal to the sum of all these forces and therefore much larger than A.
  • the anchoring lips do not simply protrude at right angles from the foot 2, but their center lines 51 run from this against the sealing lip 1. With the smallest movement of the foot 2, they are compressed on the wall of the groove 6 and wedged against it, which offers the best protection against the working out of the foot 2. If they were arranged exactly at right angles, they would only bend downwards when they were pulled out and would therefore only offer much less resistance.
  • the anchoring lips 4 are of less importance, at least in this embodiment. However, they support their effect through their symmetrical arrangement with respect to the lips 5, because each lip 4 forms with the corresponding lip 5 an arrow-shaped pair of lips directed downwards, which is pulled against the direction of the arrow. This increases the wedging effect of the anchoring lips.
  • a sealing lip 10 is now added here. It protrudes approximately at right angles from the first sealing lip 1, is curved in the opposite direction to it and protrudes away from the transition zone 11. Their purpose is an additional sealing effect against the penetration of moisture into the groove 6, which is brought about by resting on the frame 7. Because of the opposite curvature, a counter torque is exerted on the foot 2 by the resulting deformation, which reduces the effect of the torque of the sealing lip 1, thus relieving the anchoring lips 5 and putting a greater load on the anchoring lips 4. The importance of the latter is therefore greater here than in FIG. 1. However, the decrease in the total torque is only slight, because the sealing lip 10 is firstly shorter than the sealing lip 1 and secondly also less thick.
  • the tip 101 is made stronger than the adjacent part of the sealing lip 1. This results from the assembly of the strip. It is namely cut for a certain frame or a certain pane always with an albeit slight oversize, in order to be able to safely bridge any dimensional tolerances. However, there is a tendency for the strip to become somewhat longer than the corresponding frame or pane side, which means that the length is slightly compressed during assembly. If the tip were not thickened, it could warp, i.e. try to compensate for the difference in length with a wave-like course. It would therefore no longer be under pressure everywhere. Due to the somewhat more powerful design of the tip 101, this lifting is certainly avoided.
  • the two convex outer sides of the sealing lips 1 and 10 merge into one another to form a relatively large rounding 12.
  • This rounding-off serves to be able to apply a chisel-like tool 13 with which the bar or its foot 2 is driven into the groove 6 by hammer blows on this tool.
  • a special shoulder 14 which adjoins the connection area 11 must be formed there for the same purpose. Without this shoulder 14, insertion into the groove 6 would be practically impossible.
  • the strip lies on the outside of the pane 8, it could be removed by unauthorized persons who are familiar with it, whereupon the pane 8 is exposed and can then also be removed.
  • a groove 15 is provided, through which fixing elements, usually pins or nails, can be driven obliquely downwards into the frame 7. These can then hardly be removed without special tools or at most with a very large expenditure of time.
  • Other means of preventing the strip from being removed are applied adhesive layers, which, however, are preferably attached to the inside of the pane 8, not shown, between the latter and a further sealing strip or even just an ordinary support strip. The latter can also be glued so that the removal of the pane 8 is made impossible.
