Definitions

  • the invention relates to a spout for sanitary components, such as for hand basins and sinks, bath tubs or the like, with an essentially circular cylindrical sleeve-shaped water-carrying outer part and with an essentially circular cylindrical collar-shaped water-carrying inner part which is inserted into the latter, alternatively the outer or inner part of the Fixed water inlet or the pivoting outlet pipe are assigned, the outer and inner part each made of an essentially rigid hard material, in particular of metal, such as Brass, exist and are arranged rotatably relative to each other and wherein the inner part on its outer lateral surface has at least one entropy-elastic annular seal held in an annular groove as well as at least one supporting surface in the form of an axial part that extends tightly against the circular cylindrical inner lateral surface of the outer part has a circular cylindrical outer surface.
  • the collar-like inner part accommodated in the sleeve-shaped outer part forms a precision turned part with mostly two im axially spaced from each other screwed ring grooves.
  • An O-ring made of entropy-elastic material is accommodated in each of these, the hardness of which is approximately 35 Shore A at most. So that the inner part, which is usually soldered in at the end end, for example on an outlet pipe, cannot tilt in relation to the outer part during a pivoting movement, a support surface is provided - mostly between the aforementioned annular grooves - about a third of the axial length of the inner part.
  • the support surface itself which is formed from the material of the inner part made of brass, for example, is a circular cylindrical outer surface which is supported on the inner surface of the sleeve-shaped outer part with a relatively narrow sliding fit tolerance of approximately 0.02-0.05 mm.
  • the very soft O-rings only perform a sealing function, while the supporting surface of the inner part made of hard material, in particular of metal (such as brass), fulfills the supporting function that prevents canting.
  • the nipple-like inner part is a wedge precision turned part, since the ring grooves provided for receiving the O-rings are crimped.
  • the inner part accommodated with play in the outer part has no support surface.
  • the inner part can be tilted very easily due to the very soft O-rings. This in turn can lead to disadvantageous damage to the surface-refined, pivotable outlet pipe in the area of the spatially fixed union nut penetrated by it.
  • the object of the invention is to create a spout while avoiding the disadvantages of the known, which, if possible, bypassing costly precision turned parts with a very simple design, at the same time ensures low-friction and wear-free guiding of the Inner part and at the same time the required sealing effect allowed.
  • this object has been achieved in that the inner part consisting of essentially rigid, hard material is accommodated in the outer part with great play on all sides, in that each supporting surface of the inner part is made of a relatively hard set support ring which is accommodated in an annular groove and has a flat rectangular cross section entropy-elastic material is formed which, on its end face adjacent to the flow cross-section of the water, also forms as a seal a one-piece, integrally molded sealing area, which consists of two annular sealing strips which are radially self-spreading apart and have an open groove on the end face between them.
  • the inner part is accommodated in the outer part with great play on all sides.
  • the large play on all sides is compensated for by flat rectangular seals, which can be deformed entropically, otherwise, however, are set much harder compared to the previously known O-rings.
  • the fit tolerance of the support rings produced by plastic injection molding is relatively large and is in the range of approximately 0.1-0.2 mm.
  • the support ring can even have a slight oversize compared to the inside width of the outer part, so it is pressed slightly inwards over an inlet radius of the outer part when it is inserted.
  • the support surface in any case has a relatively large axial length in relation to the total axial length of the inner part, e.g. in the order of about one third of the total axial length of the inner part, the transverse forces acting radially on the pivotable part would have to be very large in order to be able to bring about a certain tilt.
  • the support ring according to the invention not only has a support function but also fulfills a sealing function if one or both of its end faces faces the flow cross-section of the water.
  • the support ring according to the invention has a sealing area integrally formed with a material fit. This sealing area consists of two annular sealing strips diverging away from the support area and forming an open groove on the end face between them. When installed, these sealing strips are against their spring return force approximated to each other and in this case lie non-positively sealing on the one hand on the inner lateral surface of the outer part and on the other hand on the inner surface of the annular receiving groove on the inner part side.
  • the ring-shaped, approximately lip-like sealing strips of the support ring according to the invention permit a flexible, adaptable, permanent sealing area due to their non-positive resilient contact with low wear-resistant friction.
  • the annular sealing strips are brought together in a compact part, the support area of the support ring, which likewise has a relatively small wall thickness, but at the same time has a relatively large axial width to ensure optimal sliding and support function.
  • the features of the main claim function together in a special combination to achieve the object according to the invention.
  • Features of the subclaims can also preferably and optionally be added to this combination.
  • the invention is particularly advantageous in the case of an outlet whose outlet tube consists of a hydraulically deformable material, such as brass.
  • a hydraulically deformable material such as brass.
  • it has two sealing end regions which are not subjected to the shaping and which are sawn off after the blank has been shaped. That the O-rings on internal part consists of a precision turned brass part already mentioned above.
  • the invention treads a new path here in that an undeformed sealing end region is used as the inner part, the flat annular grooves of which are worked into the thin wall of the inner part by cold working, in particular by rolling or forging.
  • a swivel spout is generally designated by reference number 10.
  • the outlet 10 has an outlet pipe 11, the free end of which forms a water outlet opening 12 and the inner other end of which forms a retracted, approximately bundle-shaped inner part, which can be seen in FIG.
  • the inner part 13 is received in an approximately sleeve-shaped outer part 14.
  • the circular cylindrical inner surface 15 of the outer part 14 is spaced with play s on all sides relative to the essentially circular cylindrical outer surface 16 of the inner part 13.
  • the play s is compensated for by a support ring 17 having a flat rectangular cross section.
  • the support ring 17 consists of a relatively hard set entropy-elastic material, in particular of a suitable plastic.
  • a suitable plastic can, for example, be a thermoplastic rubber elastic polyurethane (short name: TPU) be, which has a Shore hardness A of about 75-98.
  • the support ring 17 On its end face adjacent to the flow cross section Q of the water, the support ring 17 also forms a seal.
  • This seal is integrally and integrally formed on the support ring 17 which forms a plastic injection molded part.
  • This seal or sealing area 18 consists of two annular, approximately lip-like sealing strips 20, 21, which have an open V-groove 19 on the front side and are spread apart in a radially self-resilient manner.
  • the sealing strips 20, 21 are already pressed relatively closely against one another and in this way bring about a permanent, low-friction and non-positive seal both with respect to the inner lateral surface 15 and with respect to the inner surface of the groove 24 receiving the support ring 17.
  • the support ring 17 therefore has a double function: its support area 22 with its outwardly facing circular-cylindrical outer jacket support surface 23 ensures tilting secure sliding support of the inner part 13 within the outer part 14.
  • the sealing area 18 described above seals the free annular space between the inner part 13 and the outer part 14 from the outside.
  • the support ring 17 forms a thin-walled component as a whole, while the receiving groove 24 is relatively flat and can therefore be produced with a low degree of deformation.
  • a combined support and pressure ring 28 provided with a slot 25 running axially or obliquely to the surface line with an axial collar-shaped support projection 26 ensures additional radial support between the inner parts 13 and 14.
  • a flange projection 27 of the combined support and pressure ring 28 which is integral with the support projection 26 is one between the end face 29 on the outer part side and an abutment shoulder 30 at 31 screwed on the outer part 14 union nut 32.
  • the support and pressure ring 28 has approximately the cross-sectional shape of a T lying on the side and accordingly has an approximately mirror-symmetrical arrangement with respect to the support attachment 26, a collar-shaped attachment 33 pointing away from the latter.
  • the combined support and pressure ring 28 is snap-locked in a receiving groove 34.
  • the outlet pipe 11 forms a hydraulically formed workpiece, the inner part 14 forming a sealing end area during the forming and thus not subject to the hydraulic forming.
  • the axis of rotation about which the inner part 13 rotates coaxially around the fixed outer part 14 is designated by y (FIG. 2). This axis of rotation y is also entered in FIG. 5.
  • the inner part 13 a is shown very schematically. Such a fixed inner part 13 a is regularly provided with such a kitchen spout with a one-hand shut-off device, which was not shown in Fig. 5 to simplify the drawing.
  • a one-hand shut-off device which was not shown in Fig. 5 to simplify the drawing.
  • in the inner part 13 a there is only an angular one opening into a radially outwardly open water-conducting annular groove 35 Water inlet 36 provided. From the annular groove 35, the water can pass through an opening 37 into the outlet pipe 11 a, which is only partially shown.
  • the combined support and pressure ring 28 can also be produced as a plastic injection molded part, specifically from the material of the support ring 17.
  • the outer diameter D of the relaxed support ring 17 (FIG. 3) can have a slight excess compared to the inside width W of the outer part 14, 14 a.
  • the outer inlet radius R (see FIG. 2) of the inner circumferential surface 15 allows a relatively smooth axial insertion of the inner part 13, 13a provided with the support ring 17 during assembly.
  • the thin-walled support ring 17 can be easily pushed on with temporary stretching because of the end face provided with an outer radius r and thus introduced into the very flat groove 24.
