Definitions

  • the invention relates to a base part for a shower head according to the preamble of patent claim 1.
  • a base part of the type mentioned at the outset is already known from US Pat. No. 4,467,964.
  • this known floor part when using the shower head, in particular when using hard to very hard tap water, the problem arises that rapid and massive limescale deposits separate out. The lime deposits clog the water outlet openings and significantly impair the function of the base part or shower head.
  • a base part for a shower head already emerges from US Pat. No. 5,246,301, in which the water passage openings are designed as tubular extensions which project beyond the underside of the shower head.
  • the tubular extensions can both be open at their front end and have lateral slots.
  • the problem with the known base part with the hose-like extensions is that manual "rubbing", particularly due to the thin walls of the extensions, can lead to kinking, tearing or complete tearing of the extensions. This can not only significantly impair the function of the shower head, but also the possibility of removing limescale.
  • the object of the present invention is to provide a base part for a shower head of the type mentioned at the beginning, with which limescale deposits can be removed in a simple manner.
  • the shower head has u. a. a bottom part 1.
  • the bottom part 1 is provided with a multiplicity of water passage openings 2.
  • the bottom part 1 itself consists of an elastic material, preferably with a material hardness of 20 to 120 shore.
  • At least one projection 3 arranged adjacent to at least one water passage opening 2 is provided.
  • This projection 3 is connected to the base part 1 and projects beyond the outside 4 of the base part 1.
  • the projection 3 itself has no water passage opening.
  • the protrusion 3 protruding beyond the outside 4 of the base part 1 enables limescale deposits to be removed from the water passage openings 2 in a particularly simple manner. By moving the protrusion 3, this can be done, for example, by manual rubbing. the elastic bottom part 1 deforms, which leads to a change in the cross section of the water passage openings 2. In this way, lime particles that have deposited in the water passage openings 2 can be removed in a particularly simple manner from the walls of the water passage openings 2 and from the base part 1 without the risk of damaging the projection 3 or the water passage openings 2.
  • the projection 3 is particularly expedient for manufacturing reasons to form the projection 3 in one piece with the base part 1, so that the projection 3 consists of the same elastic material as the base part 1.
  • the formation of the projection 3 from flexible material is also very user-friendly. It understands themselves that the bottom part and the projection could also consist of different materials.
  • the projection 3 can basically have a knob-like or rib-like shape with a circular or oval cross-section. Of course, other cross-sectional shapes of the projection are also possible. In any case, the projection 3 should be assigned directly adjacent to at least one water passage opening 2. The direct assignment of a projection 3 to a water passage opening 2 causes an elastic deformation of the base part 1 even with slight movements of the projection 3 and thus a change in cross section of the associated water passage opening 2, which leads to an excellent limescale removal.
  • the immediate assignment is further improved in that at least one groove 5 or notch 6 is provided in the projection 3, which preferably merges continuously into the water passage opening 2.
  • the groove 5 and the notch 6 reference may be made in particular to FIGS. 2, 3 and 11.
  • the projection 3 is then inclined in the region of the groove 5 or notch 6 with respect to the vertical. This inclination with respect to the vertical can be seen, for example, in the embodiment according to FIG. 9.
  • the projection 3 has a rounded portion 7 at its outer end, which creates a pleasant feeling for the user when rubbing.
  • the base part 1 can in principle also at least partially form the underside of a shower head, it is advisable, owing to the relatively sensitive elastic material, to provide a carrier part 8 on the underside of the shower head.
  • the carrier part 8 is provided with a plurality of openings 9.
  • the bottom part 1 lies with its outer side 4 on the carrier part 8 in such a way that the respective water passage openings 2 are in the region of an opening 9. It is understood that the projection 3 is passed through the opening 9 and protrudes beyond the outside 10 of the carrier part 8.
  • pins 11 are provided on the outside 4 of the base part 1, each pin 11 projecting into an opening 9 in the carrier part 8. At least one water passage opening 2 is passed through each pin 11. In the present case, only the projection 3 adjoining the pin 11 extends, but not the pin 11 itself, extends beyond the outside 10 of the carrier part 8, so it does not protrude beyond the outside 10. However, this does not necessarily have to be the case.
  • the pin 11 projects beyond the base part 1 but not over the support part 8 and has at least one water passage opening 2.
  • the projection 3, projects beyond the base part 1 and the support part 8 and has no water passage opening 2, at most a groove 5 and / or notch 6.
  • FIGS. 1 to 11 the bottom part 1 does not have a pin.
  • the bottom part 1 is only provided with projections 3, the width or diameter of which is in each case smaller than the width or the diameter of the opening 9 of the carrier part 8.
  • the circumference of the relatively thick projection 3 in the exemplary embodiment shown two opposite grooves 5 are provided, which merge into the water passage openings 2 in the bottom part 1. It goes without saying that more than two water passage openings 2 per opening 9 or projection 3 can of course also be provided.
  • a pin 11 is provided in each case.
  • the height of the pin 11 is in no case greater than the thickness of the carrier part 8, so that the pin 11 does not protrude beyond the carrier part 8.
  • the pin 11 is offset into the opening 9, that is to say its height is less than the thickness of the carrier part 8, while the pin 11 in the embodiment according to FIG. 5 is aligned with the outside 10 of the carrier part 8. 6 and 7, the pin 11 has an inwardly inclined bevel 15 on its outside, at least in the region of the water passage opening.
  • the inward inclined bevel 15 not only makes it easier to move the projection 3 back and forth, it is also particularly easy to remove limescale deposits, which preferably occur at this point.
  • the grooves 5 or notches 6 in the embodiment according to FIG. 7 have an inclination which deviates from the vertical, while this is not the case in the embodiment according to FIG. 6.
  • the projection 3, like the pin 11, has an approximately oval shape.
  • four water passage openings 2 are provided, which are approximately the same distance from each other.
  • FIG. 10 An embodiment is shown in FIG. 10, in which the projection 3 directly adjoins the water passage openings 2, but has no grooves 5 or notches 6.
  • the corresponding explanations apply to the embodiments of FIGS. 4 to 7.
  • the shape of a wagon wheel 16 can also be selected, which is shown in FIG Fig. 11 is shown.
  • the water passage openings 2 then have the form of ring sections which are separated from one another by webs 17. Such training can be recommended at high water pressures.
