Definitions

  • the invention relates to a drain fitting intended for use in a washbasin according to the preamble of claim 1.
  • a generic drain fitting is, for example, from DE 10 2016 106 183 B4 famous.
  • the well-known drain fitting ie drain fitting, comprises a cover element which is arranged in the area of a drain opening.
  • the known drain fitting also includes a magnetic holding mechanism which is provided for positioning the cover element relative to a drain element.
  • the cover element is held in an open position by magnetic force against its weight. In the open position, the cover element is pressed in the horizontal direction against a stop on the drain element.
  • the DE 20 2016 001 893 U1 describes a drain plug for the sanitary area with magnetic extraction.
  • This drain plug is made of different materials, whereby a head part of the plug consists of magnetizable iron material with chrome plating. A pot magnet is provided to pull out the stopper.
  • drain fittings primarily intended for use in showers are in the documents DE 10 2017 000 572 B3 and DE 10 2010 047 647 B4 described.
  • the invention is based on the object of specifying a washbasin drain which is further developed than the prior art mentioned, is robust and has a simple design and uses magnetic forces for adjustment.
  • the washbasin drain in a basic concept known per se, comprises a first outer magnet provided for the transmission of actuating forces, which is arranged outside of a drain pipe and is rigid with a second one arranged inside the drain pipe magnets connected to a cover element, the central axis of the cover element being parallel at a distance from the central axis of the drain pipe, at least in a lower section of the drain pipe when installed, both in the fully open and in the closed state.
  • the lower section of the drain pipe is adjoined by a middle section of the drain pipe, which transitions into a tubular section of the drain pipe that is the upper section when installed, with an inclined section being formed in the middle section, which separates the two attracting magnets from one another and is arranged between the magnets, wherein the first outer magnet can be displaced by a pivotable actuating element and in this way interacts with the second magnet which can be displaced linearly along the inclined section.
  • the second magnet is linearly displaced along the inclined section when the first outer magnet is displaced.
  • the sloping section along which the second magnet and thus the entire cover element can be displaced, fulfills a multiple function: on the one hand, a sliding surface is provided by the sloping section, which allows a linear movement of the second Allows magnets and thus also the cover element.
  • the inclined surface ensures that the angular relationship between this surface and thus the entire drain pipe on the one hand and the second magnet and the cover element on the other hand remains unchanged in every setting of the washbasin drain. This means that no tilting movements of the cover element occur as long as there are no excessive forces acting on it that exceed the magnetic forces. However, should such excessive forces occur, the covering element can be displaced from its defined position, whereby this does not mean any destruction and the covering element returns to its defined position after the so-called excessive forces have ceased.
  • the magnet can be moved on a path in the shape of a circular arc.
  • the outer magnet can be deflected relative to the pivotable actuating element, in particular displaceable within the pivotable actuating element, such that it can be displaced along a straight path while keeping the distance from the second magnet constant on the inclined section.
  • the distance between the mutually parallel center axes of the cover element on the one hand and the lower section of the drain pipe on the other hand is at least 25% and at most 75% of the diameter of the lower section of the drain pipe.
  • the actuating element is preferably designed as a lever element which can be pivoted on the drain pipe, wherein it has a lever arm and a ring which is firmly connected to it and encompasses the drain pipe and on which the outer magnet is held on the side of the ring facing away from the lever arm.
  • the second magnet arranged within the drain pipe can be located on a rod-shaped magnet holder which is arranged in a plug connected to the cover element, with the second magnet between a foot of the magnet holder and a foot of the stopper is fixed.
  • the magnet holder and the plug can have contours to prevent rotation.
  • the plug rests laterally on a vertical wall section of the drain pipe when the cover element is raised to the maximum and thus fully opened.
  • the components drain pipe, pivotable actuating element, rod-shaped magnet holder and plug can be produced from any materials, in particular from plastic, insofar as the intended interaction between the magnets is guaranteed.
  • a washbasin drain identified overall by the reference number 1 comprises a drain pipe 2 with a cranked shape.
  • a drain pipe 2 with a cranked shape.
  • a first center axis MA1 which is spaced parallel from a second center axis MA2 given in a lower straight section 5 of the downpipe 2 .
  • the distance between the central axes MA1, MA2 corresponds to more than a third but less than 1/4 of the inner diameter of the lower section 5, denoted by D5.
  • a curved outer arc 6 is formed by the middle section 4 , which lies opposite a sloping inner section 7 , which is also part of the middle section 4 .
  • a flat contact surface 8 is formed by the inner section 7 , which is of essential importance for the function of the washbasin drain 1 .
  • a vertical contact surface 39 adjoins the upper edge of the contact surface 8, which is inclined relative to the central axes MA1, MA2. The contact surface 8 is compared to the central axis MA2 in cross section ( 6 ) by an angle ⁇ , which is 30° ⁇ 5° in the present case.
  • a lever element 14 which is generally referred to as the actuating element of the washbasin drain 1 , is mounted on the bearing journal 9 .
  • the lever element 14 has a lever arm 15 which is followed by a ring 16 which encloses the drain pipe 2 .
  • Bearing elements 17, which are attached to the ring 16, are pushed onto the bearing pins 9.
  • a magnet holder 18 is attached to the ring 16 on the side facing away from the lever arm 15 .
  • the magnet holder 18, like the bearing elements 17, has a slot which enables it to be easily slipped onto the ring 16.
  • a magnet 19 arranged in the magnet holder 18 is referred to as the outer or first magnet.
  • the figure 6 shows the sink drain 1 mounted on a sink 30 state.
  • a seal 33 is inserted between a flange 10 which closes off the upper section 3 and the underside of the washbasin 30 .
  • a groove in the flange 10 that is present for this purpose is denoted by 11 .
  • An internal thread 12 of the upper section 3 enables connection to a piece of pipe 32 which is arranged in a drain opening 31 of the washbasin 30 .
  • a seal 36 is used to seal between a cover 35 of the sink drain 1 and the piece of pipe 32.
  • the magnet 25 is held with the help of a magnet holder 20, which is figure 4 is shown in isolation.
  • the magnet holder 20 has a head, designated 21, on the circumference of which a slot 37 is located.
  • a shaft 22 of the magnet holder 20 connects to the head 21 .
  • Ribs 23 can be seen in a section of magnet holder 20 below shaft 22 .
  • the magnet holder 20 is closed at its lower end by a foot 24 on which the magnet 25 is located.
  • the entire magnet holder 20 including the magnet 25 is inserted into a plug 26, which is available as a single part in figure 5 is shown.
  • the upper end is designed as a funnel-shaped head part 27, which has a web 38 on its inner peripheral surface, which represents the counter-contour to the slot 37.
  • a sleeve-shaped section 28 of the plug 26 connects to the funnel-shaped head part 27 .
  • the designated 29 foot of the plug 26 has an inclined Closing surface 40, which is provided for contacting the contact surface 8 of the drain pipe 2.
  • the plug 26 contacts the drain pipe 2 exclusively on the contact surface 8 as long as the sink drain 1 is not fully open.
  • the full opening of the washbasin drain 1 is equivalent to the sleeve-shaped section 28 hitting the vertical contact surface 39 .
  • the arrangement of magnet holder 20, plug 26 and inner magnet 25 can be held against the forces between the magnets by forces acting on the cover 35 from the outside 19, 25 acting forces are displaced downwards. If the external forces cease, the inner magnet 25 and thus also the cover 35 are pulled back into their previous position. Otherwise, changes in the position of the cover 35 are provided exclusively by actuating the lever element 14 .
  • a cleaning of the washbasin drain 1 is possible in the simplest way if the inherently rigid arrangement of cover 35, magnet holder 20, plug 26 and inner magnet 25 is removed from the pipe section 32 and the drain pipe 2.
  • the arrangement comprising the piece of pipe 32 and the discharge pipe 2 adjoining it does not have any transverse webs or similar obstacles that could promote the accumulation of dirt or impede the removal of non-liquid waste water components. If the arrangement of cover 35, magnet holder 20, stopper 26 and inner magnet 25 is reinserted into the piece of pipe 32 and the drain pipe 2, the correct alignment between the magnets 19, 25 is established by the acting magnetic forces.
