Definitions

  • the invention relates to a fastening device for fastening a toilet seat set to a ceramic according to the preamble of claim 1.
  • Such fastening devices are used to hold toilet seat joints on a ceramic, the toilet seat joints allowing the toilet seat set consisting of toilet seat and toilet lid to pivot on the peripheral edge of the ceramic.
  • a fastening device for a toilet seat joint is known, for example, from DE 102 33 733 A1 of the applicant.
  • the fastening device is connected to the ceramic by screwing.
  • the fastening device has a base plate which rests on the ceramic and to which a threaded pin is fastened which penetrates a through-hole in the ceramic.
  • a lock nut is screwed onto the end section of the threaded pin protruding from the ceramic, so that it comes into contact with a lower support surface of the ceramic. Sufficiently tightening the lock nut fixes the base plate and thus the fastening device to the ceramic.
  • the toilet seat joint is then placed on the fastening device via a hinge pin arranged on the base plate and the toilet seat set is thereby held pivotably on the peripheral edge of the ceramic.
  • Adhesion of this type has the advantage that, on the one hand, a screw connection is not susceptible to contamination due to the difficult-to-access areas through which the screw connection passes. Furthermore, no through-holes have to be formed in the ceramic, since only a comparatively flat adhesive surface, which is already present, has to be provided on the ceramic.
  • the invention is based on the object of creating a fastening device by means of which the fastening of a toilet seat set to a ceramic is further simplified.
  • the fastening device has a base plate which can be fastened to the ceramic by means of an adhesive and which carries a pin or a receptacle for a pin of a toilet seat set.
  • a base plate which can be fastened to the ceramic by means of an adhesive and which carries a pin or a receptacle for a pin of a toilet seat set.
  • the invention is on a bottom surface of the Base plate formed at least one support projection, the base area of which is significantly smaller than that of the bottom surface.
  • This support projection is designed with a support surface that carries an adhesive layer.
  • the invention accordingly turns away from the previously pursued concepts in which the bottom surface is glued to the ceramic over the entire surface and instead uses a support surface that is partially limited to the base plate, which ensures that the gluing takes place in the predetermined manner.
  • the actual floor area thus runs at a distance from the ceramic.
  • the invention covers two construction principles, in one variant the pin is attached on the ceramic side and in a so-called inverse system (inverse concept) the pin is formed on the toilet seat joint and dips into a corresponding receptacle in the base plate.
  • inverse system inverse concept
  • a plurality of such support projections are formed so as to cantilever from the bottom surface, so that the bonding takes place over a corresponding plurality of support surfaces.
  • three support projections can be provided lying on a common pitch circle, so that a stable support of the base plate is guaranteed, which can also withstand high loads. Any unevenness in the ceramic surface can easily be absorbed by this partial support.
  • the pin is screwed to the base plate or embossed so that the pin and the base plate can be produced in separate production steps.
  • a one-piece solution can of course also be selected.
  • the screw connection can take place, for example, by means of a threaded bolt which is inserted, preferably pressed into, the base plate from the bottom surface.
  • the gap between the bottom surface and the ceramic and thus also the support projections extending out of the bottom surface can be covered by a cap through which the pin passes.
  • the cap has a cylinder jacket-shaped side wall which laterally encompasses the circumference of the base plate and the support projections extending away from the bottom surface.
  • the cap can furthermore be designed with a recess through which the pin or the receptacle extends.
  • the support of the base plate is particularly stable when the support projections are arranged closer to the side wall of the cap than to the central recess.
  • radial projections are formed on the outer circumference of the base plate, which can then also be covered by the cap.
  • FIG. 1 shows a greatly simplified 3D illustration of a fastening device according to the invention and a detail of an inverse fastening device;
  • FIG. 2 shows a three-dimensional representation of a first exemplary embodiment of a fastening device
  • FIG. 3 shows a view obliquely from below of the fastening device according to FIG. 1 and a partial section;
  • FIG. 4 shows the fastening device according to FIGS. 2 and 3 with the cap removed
  • FIG. 5 shows an exploded view of the fastening device according to FIG. 2;
  • FIGS. 6, 7 are views of a further exemplary embodiment of a fastening device
  • FIGS. 6 and 7 shows the fastening device according to FIGS. 6 and 7 with the cap removed and
  • FIG. 9 shows an exploded view of the fastening device according to FIGS. 6 and 7.
  • FIG. 1 shows a three-dimensional representation of a fastening device 1 which is used for the detachable folding of a toilet seat joint 2 of a toilet seat set (not shown) on a ceramic 4 indicated by dash-dotted lines.
  • the toilet seat joint 2 enables the toilet seat set resting on the ceramic 4, consisting of a toilet seat and a toilet lid, to be pivoted.
  • a pin 6 of the fastening device 1 dips into a receptacle 8 of an adapter piece 10 of the toilet seat joint 2.
  • the pin 6 is glued to the ceramic 4 via a base plate 12.
  • the pin 6 is connected to the base plate 12 (see FIG. 3) by stamping / blackmailing.
  • this base plate 12 is covered by a cap 14 which, according to FIG. 3, engages around the base plate 12.
  • the pin 6 - also called the hinge mandrel - is in principle cylindrical and has, for example, two annular grooves 16, 18 on its end section dipping into the receptacle 8, into which, for example, an O-ring or a spring ring is inserted, which is used for sealing or locking the adapter piece 10 contributes.
  • a mounting slot 20 is also formed on the end face of the pin 6, to which a screwdriver can be attached, for example for mounting or the like.
  • support projections 24a, 24b, 24c lying on a common pitch circle are formed, with which the fastening device rests on the ceramic 4.
  • the support projections 24 can be bush-shaped with an inner bore 26 (see support projection 24c) so that annular adhesive surfaces 28 are formed, which are covered, for example, by an adhesive film in the delivery state.
  • the axial length I of the support projections 24 corresponds approximately to the fleas h of a cap side wall 30 which laterally engages around the base plate 12 with the support projections 24 and thus covers it, but the secure support of the support projections 24 on the ceramic 4 is ensured. This is indicated by the detailed sectional view in FIG. 3 at the top right.
  • the base plate 12 is designed with a dome 32 in which a recess 34 is formed in the center, through which a tapered end section 36 of the pin 6 has a press fit.
  • This dome 32 is, so to speak, stamped / pressed with the end section 36 of the pin 6.
  • This dome 32 can be seen particularly well in FIG. 4, which shows a view obliquely from above onto the fastening device 1 with the cap 14 removed. Accordingly, the dome 32 bulges centrally upwards towards the pin 6 out of the base plate 12, the pin 6 being inserted into the recess 34.
  • the base plate 12 and the support projections 24a, 24b, 24c and the dome 32 are formed in one piece by stamping. This embossing is carried out in such a way that the bearing projections 24 are formed from the base material by reshaping and thus extend out of the bottom surface 22 in the shape of a bush.
  • FIG. 6 The individual parts of the exemplary embodiment described are shown again in FIG. 6 in an exploded view.
  • the base plate 12 With the previously described dome 32, the central recess 34 and the three support projections 24a, 24b, 24c extending opposite to the dome 32 shown.
  • this base plate 12 is formed from a flat material by stamping and embossing, so that it can be manufactured in one operation.
  • the pin 6 shown above in Figure 5 is - as explained above - cylindrical and has the assembly slot 20 and the annular grooves 16, 18 for receiving a sealing ring 18 (O-ring or a spring ring) on its upper end portion.
  • the end section of the pin 6 that is remote from the assembly slot 20 is stepped back radially, so that the end section 36 which plunges into the dome 32 is formed.
  • the pin 6 is supported on the base plate 12 - more precisely on a support surface 40 of the dome 32 - via an annular shoulder 38 produced by this stepping back.
  • the cap 14 is placed on the base plate 12 before the embossing, so that the pin 6 with its radially recessed end portion 36 is inserted into a central opening 42 of the cap 14 and the recess 34 of the dome 32 and then embossed will. Since the dome 32 has a relatively large overall height, a chamfer 44 is formed on the outer circumference of the cap 14 in order to improve the design - however, this is only an optional solution.
  • the three support projections 24a, 24b, 24c lie on a common pitch circle, the radius of which is selected such that it is arranged closer to the side wall 30 than to the recess 34.
  • the support projections 24 are arranged offset towards the side wall 30, so that the support is optimized.
  • this exemplary embodiment differs from that according to FIG. 2 only in that the height of the side wall 30 of the cap 14 is designed to be lower than in the previously described exemplary embodiment.
  • This flatter design is - as explained below - by the execution of the Base plate 12 without dome 32 allows. Otherwise, the view according to FIG. 6 corresponds to that in FIG. 2, so that further explanations are unnecessary.
  • the base plate 12 is not designed in the shape of a disk with a round circumference, but the outer circumference of the base plate 12, which is encompassed by the side wall 30 of the cap 14, is represented by, for example, three or more Circumferentially distributed radial projections 46a, 46b, 46c are formed, which are arranged radially outside the three support projections 24a, 24b, 24c.
  • a press-in threaded bolt 48 is pressed into the central recess 34 of the base plate 12, the threaded section of which protrudes from the base plate 12 towards the pin 6, so that the pin 6 can be screwed onto this threaded bolt 48
  • FIG. 8 shows this screwed-on state without the cap 14.
  • a bevel 52 is implemented on each radial projection 46a, 46b, 46c which is dimensioned in accordance with the bevel 44 of the cap 14.
  • the three bearing projections 24a, 24b, 24c aligned with respect to the radial projections 46 are reshaped by stamping from the large area of the base plate 12.
  • FIG. 9 shows an exploded view of the fastening device according to FIGS. 6 and 7.
  • the base plate 12 is designed with the three radial projections 46a, 46b, 46c and the support projections 24a, 24b, 24c aligned therewith.
  • a dome as in the exemplary embodiment described above, is not present - the recess 34 for the press-in threaded bolt 48 is provided in the center.
  • This has a press-in collar 54 which has approximately the wall thickness of the base plate 12 and which is pressed into the recess 34.
