Definitions

  • the invention relates to an outlet fitting for washstands, Bidets or similar facilities.
  • Such outlet fittings are from the German published documents DE 43 20 790 A1 and DE 44 43 668 A1 known.
  • a pressure plate with a location hole intended for the threaded rod which also a radial slot for receiving the connecting pipes and an actuating linkage for a Has drain valve of a wash basin etc.
  • the radial slot formation arises only proportionally small contact surface on the pressure plate for the Dashboard, so that when properly fixed the outlet fitting has a relatively high surface pressure arises on the pressure plate.
  • the pressure plate be made of a high strength Making plastic or even metal is what it is causes relatively high costs.
  • German patent application DE 43 01 502 A1 is also a sanitary fitting for a sink known in the case of a flat disc as a counter element with one that extends over an angle of 360 ° Contact surface is provided.
  • the flat disc is from one to the sanitary fitting screw-in threaded bolt with a cap nut Head elements braced against the sink.
  • here is an additional seal for the System provided at the sink.
  • the flat disc has two openings, in which either Threaded bolt can be inserted.
  • the invention is based on the object in the preamble of claim 1 specified fastening device to train so that a cheaper Manufacturing is enabled, but safe, overuse Avoiding mounting of the valve guaranteed remains.
  • the contact surface of the pressure plate on the dashboard be significantly increased so that the surface pressure reduced accordingly.
  • an inexpensive high-strength plastic an inexpensive plastic material, such as Polyamide, or even a cheaper one Use regenerated plastic.
  • a separate through-opening for guiding the line can advantageously be formed in the pressure plate for each of the connecting lines, so that an undesirable kinking of the line in the area of the fitting is avoided, which can occur in particular in the copper pipeline which is frequently used.
  • a slight lateral bending of the copper pipes allows the pressure plate to self-lock in the plug-in position, so that the valve can be easily screwed on.
  • bulky connecting lines such as. B. hose lines
  • a protruding one can be found on the mother's head piece Part provided and with a defined Vulnerability to be connected to the mother so that at a predetermined torque, the above Part tears off.
  • a water outlet fitting is shown in the form of an engagement mixer valve.
  • a connector 3 is embedded, to which connecting lines 31 for the incoming cold and hot water are connected in a known manner.
  • the connector 3 is arranged sealed in a bore of the fitting housing 1 and carries a threaded rod 4 on the face parallel to the connecting lines 31.
  • a known mixing valve 2 is arranged on the opposite end of the connector 3, which can be adjusted in two degrees of freedom by means of a handle 21, namely in a first degree of freedom the mixing ratio of the incoming cold and hot water and in a second degree of freedom the total flow rate of the outflowing water.
  • the mixed water generated in the mixing valve 2 is discharged via an outlet 11 as a free jet.
  • the fitting housing 1 is attached with a base to a surface of a fitting bench 7 of a washstand or sink, the threaded rod 4, the connecting lines 31 and an actuating linkage 12, which serves for a drain valve (not shown in the drawing) of a sink or sink an opening 71 are passed.
  • a pressure plate 5 made of plastic, preferably of regenerated plastic, e.g. B. made of polyamide (PA).
  • a through hole 51 for the threaded rod 4 and cylindrical through openings 53 for the connecting lines 31 for cold and hot water and a through opening 54 for the actuating linkage 12 are formed in the pressure plate 5.
  • the through openings 53 are designed in diameter so that the connecting lines designed as copper pipes are guided with little play in the through openings 53.
  • the pressure plate 5 has a closed outer circumference 50 or a closed circular geometry, so that the pressure plate 5 with a continuous outer ring surface 55 comes to rest against the valve bank 7 in the fastening position.
  • a nut 6 is provided, which must be screwed onto the threaded rod 4 by means of thread 60.
  • the nut 6 here has an approximately cylindrical base part 64 with which it can be inserted into a depression 511 in the through bore 51 of the pressure plate 5.
  • a head piece 61 provided with a polygonal profile - preferably hexagon - is formed on the base part 64.
  • a projecting part 611 is formed on the head piece and is connected to the rest of the head piece 61 via a defined weak point 62. The weak point 62 is dimensioned so that the part 611 tears off the nut 6 at a predetermined torque.
  • the projecting edges of the polygonal profile are each provided with a flattening 63, which are dimensioned such that a turning tool, e.g. B. socket wrench - slips above the permissible torque under an elastic deformation of the polygonal profile, so that even after removing the projecting part 611 of the head piece 61 it is ensured that only the permissible torque can be applied to the nut 6 with a turning tool.
  • a turning tool e.g. B. socket wrench
  • the fitting housing 1 containing the one-handle mixing valve can be installed on the fitting bench 7 in the following way:
  • the housing 1 with inserted connector 3 and connecting lines 31 and with the mixing valve 2 is inserted with the threaded rod 4, the connecting lines 31 and the mounting rod 12 through the opening 71 in the valve bank 7 until the front face of the valve housing 1 abuts the surface of the valve bank 7.
  • the pressure plate 5 can be pushed onto the connecting lines 31 and the actuating linkage 12 as well as onto the threaded rod 4 up to the plant on the underside of the valve bank 7 under the valve bank 7.
  • a protrusion 56 of the pressure plate 5 is centered in the opening 71 of the valve bank 7.
  • the two connecting lines 31 made of copper pipe can be bent slightly sideways so that the pressure plate 5 is self-locking. Then the nut 6 can be screwed onto the threaded rod 4. Then afterwards with a turning tool, e.g. B. a socket wrench, the nut 6 via the part 611 with a clamping torque. As soon as the required torque for the bracing occurs, the part 611 tears off the nut 6 and the valve is firmly installed on the valve bank 7. Thereafter, the connecting lines 31 can be connected to the supply lines and the actuating linkage 12 to the drain valve, not shown in the drawing, below the instrument bank 7.
  • a turning tool e.g. B. a socket wrench
  • the pressure plate 5 can be pushed together with the nut 6 as a unit onto the connecting lines 31 with the actuating linkage 12 and screwed onto the threaded rod 4.
  • a lateral bending of the connecting pipes for holding the pressure plate 5 in the inserted position is not necessary.
  • FIGS 3 and 5 is a modified printing plate 5 shown.
  • the separate cylindrical openings 53 for the individual connecting lines 31 and the opening 54 for the actuating linkage 12 is here only one through opening 52 is formed, through which all connection elements are passed.
  • Such training is particularly useful if if connecting cables with larger diameter be provided as it is e.g. B. with hose lines with metal braid reinforcements etc.
  • this embodiment corresponds to that in FIGS 3 shown printing plate 5th
  • the pressure plate 5 is in the above Embodiments of regenerated polyamide in the injection molding process manufactured. Mother 5 is also out Polyamide (PA) manufactured by injection molding.
  • PA Polyamide
