Definitions

  • the invention relates to a water inlet for flat roofs, consisting of a one-piece component made of a funnel-shaped inlet body, which contains a plastic ring, on the outer circumference of which a connecting foil forming a collar ends.
  • a water inlet which consists of two parts, namely on the one hand an inlet body, on the other hand an integral unit made of a plastic ring and a connecting foil.
  • This unit can be connected to the inlet body via cams provided on the plastic ring, which interact with grooves in the inside wall of the inlet body in the manner of a bayonet lock.
  • a water inlet constructed in two parts in the same way is also known from DE-A-26 12 684, however, in order to connect the unit made of plastic ring and connecting foil to the inlet body, the plastic ring designed as a seal and correspondingly profiled is form-fitting to the one provided with a complementary profile Inlet body pressed on.
  • connection film blanks In addition to the disadvantage of not being able to use smooth, flat-lying connection film blanks, it is difficult, if not impossible, to position the plastic ring and the part of the connection film to be embedded in the mold cavity of the tool for producing the water inlet and during the spraying , Pouring or foaming to be positioned so that the desired embedment depth and a central position of the plastic ring to the axis of the water inlet are maintained.
  • a relatively high strength plastic must be used for the inlet body if - as usual - inlet sieves or extension elements are to be anchored sufficiently securely on the inner wall of the water inlet.
  • the invention has for its object to design a water inlet of the type specified in the introduction so that it can be produced in a time-saving manner from the simplest possible shaped parts.
  • the inlet body is formed on the underside of the connection film and the outside of the ring, that the top of the connection film and the upper end face of the ring lie in one plane, that the connection film in a groove in the outer circumference of the ring close whose upper end face ends, and that the inner surface of the ring forms the inlet-side, first section of the inner wall of the water inlet.
  • This embodiment has the advantage that the plastic ring and thus also the connection film, which is only loosely attached to it, are positioned centrally by the core of the molding tool, the later upper end face of the ring and the later upper side of the connection film resting against one end wall of the mold cavity can. Even if high pressures occur during the subsequent molding of the inlet body, as is the case with the foaming process that is preferably used, no more displacements can occur.
  • the ring consists of a plastic of higher strength than the inlet body and has in its inner surface an inwardly opening, circumferential groove which is connected to the upper end face of the ring by way of circular segment-shaped recesses.
  • the higher strength of the plastic ring ensures secure anchoring of, for example, an inlet strainer or an extension element.
  • the circular segment-shaped recesses and the internal, circumferential groove allow a bayonet-type insertion of such an inlet sieve. Instead, a sealing ring can also be inserted into the groove and then an extension element can be inserted.
  • the circular segment-shaped recesses also increase the water absorption capacity of the water inlet.
  • the ring advantageously ends on the outlet side in a sealing lip which closes with the inner wall of the inlet body. This prevents the material, e.g. Plastic foam, between the mold core and the plastic ring.
  • the ring is provided on its outside with angularly offset webs.
  • these can serve for the largely automatic positioning of the connecting foil and the ring in the mold while it is being closed, and on the other hand they improve the anchoring of the ring in the material of the inlet body.
  • Another embodiment is characterized in that a support body for an electrical heating conductor is fixed on the outside of the ring in the outlet-side section thereof. With negligible additional effort, this ensures that the heating conductor is molded in a precisely predetermined position.
  • the water inlet consists of an inlet body 1, which is connected to a plastic ring 2 and is foamed onto a connecting foil 3 in such a way that the top of the connecting foil 3 and the upper end face of the ring 2 form a flat connecting flange.
  • Fig. 2 illustrates the position of the water inlet before it is removed from the foam mold.
  • This consists of a movable molded part 13 and a fixed molded part 14 which is integral with a molded core 14a.
  • the ring 2 is provided in its upper, inlet-side part with an outer circumferential groove 4, in which the film 3 ends.
  • the ring 2 also has e.g. three webs 8 offset by 120 °.
  • the movable molded part 13 presses the inserted ring 2, including the film 3 lying loosely in its groove 4, over these webs 8 into the end position.
  • the ring 2 is provided on the inside with a circumferential groove 5, the purpose of which will be explained later.
  • the ring 2 ends in a sealing lip 11 which prevents the plastic foam forming the inlet body 1 from getting between the ring 2 and the mold core 14a.
  • Fig. 3 shows a second embodiment of the water inlet.
  • a sealing ring 9 is additionally inserted, which fixes the film 3 better in the groove 4 and prevents plastic foam from getting between the fixed molded part (14 in FIG. 2) and the film 3.
  • a carrier body 19 for a heating conductor 12 is pushed onto the outlet-side end of the ring 2 and is supplied with current via a connection 12a.
  • FIG. 4 shows the water inlet according to FIG. 1 in connection with an extension element 20.
  • the extension element 20 is constructed in the same way as the water inlet itself.
  • an O-ring 6 is inserted into the inner circumferential groove 5.
  • FIG. 5 illustrates the water inlet according to FIGS. 1 and 2 in two different partial longitudinal sections.
  • recesses 7 in the form of segments of a circle are provided on the ring 2, via which the inner groove 5 is connected to the inlet cross section with a smooth surface.
  • three such circular segment-shaped recesses 7 offset by 120 ° can be provided.
  • an inlet screen 15 can be used with, for example, three feet 16 in the ring 2 and thus in the water inlet and secure by twisting by a certain angle in such a way that the outwardly facing projections of the feet 16 then into the groove 5 come to rest according to the position shown on the right in FIG. 5.
  • the inlet sieve 15 is secured against inadvertent rotation by, for example, three recesses 17, each offset by 120 °, the lateral surfaces 18 of which act as stops for the feet 16.
