Definitions

  • the present invention relates to a door and / or window stopper according to the features of the preamble of claim 1 and a method for producing the same.
  • Such a door and / or window stopper contains an inner part of a band-shaped piece of metal.
  • the inner part is provided with a coating formed from a resilient material, such as rubber or leather or plastic, wherein the overall stiffness of this outer part is essentially predetermined by the inner part.
  • the band-shaped metal piece has over the longitudinal extent of the stopper on a constant wall thickness, the overall stiffness over the longitudinal extent is virtually unchanged.
  • the tip of the outer part ends at the top of the inner part.
  • This stopper as a whole consists of a rubber-elastic body with a high coefficient of friction with a certain shape, which has a tapered region which is particularly flexible. At the tip region in the direction of a longitudinal axis of the body is then a comparatively wider or thicker and substantially round area available, and the stopper or body thus has a teardrop-like shape and / or outer contour.
  • This shaping allows the use in gap areas of open doors and / or windows, in order to secure them from accidental closing, such as by wind draft.
  • a disadvantage of these stoppers is the full shape, so that the manufacturing costs are relatively high due to the cost of materials and also a limited spring travel is given.
  • a window and door stopper which has a tip in a triangular tapered inner part in various embodiments.
  • the inner part is not formed like a bracket and as far as possible stiff such that a achievable in the region of the tip flexibility is determined solely by the flexible outer part.
  • the present invention is based on the object to further develop the door and / or window stopper of the type mentioned that simplifies the production and the material usage and / or weight are reduced and still the essential features, such as a high flexibility and a Use in wide gap areas, be enabled. Furthermore, a larger spring travel is to be made possible in a simple manner.
  • the solution of this task is carried out with regard to the door and / or window stoppers according to the features of claim 1 and further with respect to the method according to the features of claim 6.
  • the clip-like inner part stiffens the thin-walled and thus relatively soft material of the outer part, wherein a buckling transverse to the longitudinal plane, which runs through the door and window stop, is avoided.
  • Transverse to the longitudinal plane of the door and / or window stopper which is hereinafter referred to briefly as a stopper, preferably has a substantially constant width.
  • the clip-like inner part has at its tip and / or the tip of the outer part towards decreasing wall thickness, so that a similar flexural rigidity and elasticity as in the EP 1 472 426 B1 known door and window stoppers are achieved without this becomes unstable.
  • the tip of the outer part projects beyond the tip of the inner part with a predetermined length, which in particular is considerably larger than the thickness of the outer part in the region of the surrounding inner part. If you choose the wall thickness of the inner part accordingly thin, so arise for the present purposes particularly suitable properties, the Tip of the outer edge forming the outer edge of the stopper together with the region of the tip of the inner part as a whole have a high bending strength and / or under load and / or force components in or parallel to the longitudinal plane allow a large spring travel.
  • the elasticity of the entire body is determined in particular by the wall thickness of the inner part and its course.
  • the stopper is hollow on the inside, the edge and / or arm compressed under load, in particular in the region of the tip of the inner part, can deflect inwards, as a result of which the spring travel is markedly increased.
  • the contour is predetermined such that the stopper can be pressed together and forms an outer curve or reinforces it.
  • triangular contours, ellipsoidal or crescent-shaped contours are possible as hollow shapes.
  • the inner part is advantageous as an open or closed to the one or more tips clip-like inner part of a resilient material, for.
  • a glued sheet or plastic in particular, is formed, wherein the outer part on the one hand by the relatively high coefficient of friction for a secure fit, z. B. in a gap between the window and frame, but on the other hand also strengthens and / or increases the spring action of the inner part.
  • the outer part has, advantageously in its areas surrounding the inner part, by a predetermined factor, which is greater than 1, preferably considerably greater wall thickness than the inner part in the region of its tip and / or in the end region of the stopper.
  • the inner part is preferably made of polypropylene (PP), and / or materials and / or plastics with different melting points are used for the outer part and the inner part.
  • the melting temperature of the outer part in particular of thermoplastic elastomer (TPE) at 180 ° - 220 ° C, above that of the inner part, in particular of polypropylene (PP) with substantially 170 ° C and a softening temperature of substantially 140 ° C, and / or in ranges of ⁇ 10%, in particular ⁇ 5% to at least one of the aforementioned temperatures.
  • the wall thickness of at least one arm of the inner part tapers advantageous towards the tip.
  • a similar and / or preferably increased bending stiffness and elasticity can be achieved as with solid rubber, without the entire body becoming unstable. Since in the region of the tip of the inner part, in particular due to the reduced wall thickness, the arms of which are mutually movable under load, a total of a large and / or significantly increased travel of the stopper is given.
  • the production can thus be carried out by first injecting and / or pouring the inner part in a mold and then ejecting and / or pouring the outer part.
  • the cooling of the inner part can be done up to the range of the softening temperature.
  • the present invention further enables a predetermined breaking point that is particularly easy to produce. This is important when trying to close a window or door with great force, ignoring the presence of a stopper in the frame. This is achieved in an elegant manner by selecting the Ausspritztens for the inner part such that the confluence of the melt (PP) of the inner part happens exactly at the point such that the enamel fronts meet at the predetermined breaking point. On the way there, the fronts cool off from the injection temperature and / or this one is chosen so that the connection does not pass through here Flow into each other, but essentially by adhesion happens and thus at this point the structure is weakened.
  • PP confluence of the melt
  • the injection point is in this case not equidistant from the predetermined breaking point due to the material viscosity and the edge friction. Since the predetermined breaking point is sensitive to tensile forces, moreover, the predetermined breaking point is preferably in the convex region of the rounded or ausurundenden part of the stopper.
  • the injection mold can also be cooled at the location of the intended breaking point.
  • Another quite simple and cost-effective method for producing the stopper according to the invention is that these are injection-molded in the so-called mono-sandwich method in a simple tool, the plastics of the outer part and inner part.
  • the TPE is introduced into the mold and this hot liquid displaced by subsequent plastic of the inner part with greater flexural rigidity.
  • the effect here is that the plastic of the outer part, in particular TPE, is pushed into the region of the tip (s) and thereby adheres to the walls of the mold by slightly cooling with an increase in viscosity on the walls and forms a shell for the following plastic.
  • the injection point (s) are ideally chosen in such a way that the path for the TPE from this to the tip or the tips is always the same length, the cross sections in the tool being assumed to be the same.
