Definitions

  • the invention relates to a drain plug for a drain fitting in particular a kitchen sink according to the preamble of claim 1.
  • Such drain plugs are used in particular in kitchen sinks to close the recessed in the bottom of a sink drain, so that water can be collected within the sink. Crockery or food such as salads or fruit can then be conveniently cleaned in the water-filled sink.
  • the drain plug For Verkipp Kirs the drain plug whose guide pin is inserted from above into a corresponding guide sleeve of the drain fitting.
  • a user can change the vertical position of the drain plug by actuating a lever, usually located outside the sink, of a device not further described herein.
  • the drain plug is brought about its guide pin from a sealing position in which the sealing element closes the drain against the leakage of the rinse water in an open position, which allows a flow of water.
  • drain plugs are known in which the cap is formed basket-shaped is with a circular, flat cap bottom and an adjoining, curved upwards running edge of the cap. This cap edge has openings, which will be explained below.
  • Such a drain plug is generally located in one opposite the other bottom of the sink recessed drain, so that it rests with its usually circular outer edge on the wall of the drain.
  • openings in the cap edge of the drain plug can remain both in the sealed and in the open position within the drain, since the rinse water can flow in the open position through the openings.
  • the thus provided with openings cap also serves as a sieve, in which, for example, food residues that have collected in the rinse water, settle. By vertically lifting the drain plug from the drain, these food remnants can be conveniently disposed of as needed.
  • an end-side pin of the guide pin is inserted from the bottom of the cap through a central through hole of the cap base.
  • the length of the pin is dimensioned so that a large part of the same emerges on the upper side from the through hole.
  • the diameter of the pin is smaller than the diameter of the remaining guide pin, so that a step is formed, which rests from below against the cap base.
  • a fixing cap is now fixed, for example by Preßversch spaung for axial fixation of the guide pin.
  • the fixing disc which has a circumferential annular groove into which an annular sealing element can be inserted.
  • the fixing plate in turn is attached to the underside of the cap base.
  • the fixing washer like the cap base, has a through hole corresponding to the guide pin, which is penetrated by the pin before it is inserted through the through hole.
  • the axial fixation of the three parts, so the cap, the guide pin and the fixing plate is also achieved here by a connected to the guide pin pin by Preßsch spaung fixing.
  • gaps occur at the contact surfaces of the components, which usually consist of metal, in which moisture can accumulate, which promotes or sets in motion corrosion processes.
  • these gaps occur between the bottom of the fixing cap and the cap bottom top, between the cap bottom bottom and the fixing ring and finally between the fixing ring and the guide pin.
  • the gaps are now also comparatively narrow, they are difficult to access when cleaning the drain plug, so that the above effects can hardly be prevented.
  • the present invention is therefore based on the object to avoid the disadvantages of the known in the prior art drain plugs, in particular to simplify the connection of the guide pin and the sealing element with the cap, so that in particular the number of difficult to clean column is reduced, in which Bacteria or moisture can collect.
  • the guide pin is held in the cap recess by the pressure exerted by the cap inner wall.
  • the guide pin is thus manufactured with excess over the smallest inner diameter of the Kappenausbuchtung and pressed into the same, which is a simple, inexpensive connection method.
  • the guide pin is held by a clamping element in the cap recess.
  • an additional clamping element is provided, via which the guide pin is indirectly attached to the cap.
  • This additional clamping element opens the possibility to choose the diameter of the guide pin regardless of the inner diameter of the Kappenausbuchtung.
  • the inner diameter of the Kappenausbuchtung it is convenient, the inner diameter of the Kappenausbuchtung to be as large as possible, so that the cap bulge can be optimally used by a user as a handle knob on which the drain plug can be used for lifting out of the drain.
  • the guide pin diameter should be kept as small as possible so that the cross section of the drain fitting, through which the waste water flows, is as large as possible. Since the guide pin sits in the guide sleeve of the drain fitting, but it ultimately reduces the cross-section.
  • the mentioned clamping element now makes it possible to meet these two conflicting requirements by balancing the different dimensions of guide pin and cap bulge.
  • connection between the guide pin and the clamping element it is advantageous if the guide pin is pressed into the clamping element, since this is a simple and cost-effective connection option.
  • the guide pin has at one end a screw-head-like approach, with which it sits in a stepped bore of the clamping element. Then the guide pin during assembly can be easily inserted from above into the stepped bore of the clamping element.
  • clamping element can be locked by captive means captive in the Kappenausbuchtung. It is particularly advantageous that the assembly of clamping element and cap later, that may even be carried out by the customer under certain circumstances.
  • the shape of the clamping element may advantageously be disc-shaped with a central bore for receiving the guide pin.
  • the wall of the Kappenausbuchtung is substantially hollow cylindrical, so that the disk-shaped clamping element rests over its entire circumference on the inner wall of the Kappenausbuchtung, which ensures optimum radial fixation of the clamping element.
  • the upper side of the disk-shaped clamping element have a circumferential annular groove.
  • annular groove a certain flexibility of the upstanding edge of the clamping element is achieved, which may initially facilitate the insertion of the clamping element in the Kappenausbuchtung.
  • the clamping element made of plastic, so that it increases only slightly by its comparatively low weight, the total mass of the drain plug. Furthermore, a clamping element made of plastic is not susceptible to corrosion and beyond easy to manufacture as an injection molded part.
  • the sealing element As far as the sealing element is concerned, it is favorable if it is arranged on the clamping element.
  • the clamping element is made of plastic, it is expedient to provide on the clamping element devices by which the sealing element is held there.
  • sealing element is inserted in a corresponding annular groove of the clamping element.
  • sealing rings made of rubber or elastomer can be used.
  • the wall of the cap recess on the outside has at least one indentation directed toward the central axis for engagement.
  • a user who wishes to lift or transport the drain plug can comfortably grasp the drain plug at this recess of the side wall.
  • this indentation allows a non-slip gripping the plug.
  • the indentation runs along the entire circumference of the cap bulge. This creates a rotationally symmetric indentation that allows the user to grasp the plug at the indentation with one hand, without having to look directly at it.
  • the cap with the bulge formed thereon is integrally deep-drawn, so that welds or similar joining techniques are avoided.
  • the cap is made of corrosion-resistant stainless steel.
  • FIG. 1 shows a plan view of a circular sink outlet 1 of a kitchen sink. Since it is the flushing process, as well as the sink itself, is a common component, this will be described in the following only briefly - understanding half.
  • the rinse drain 1 is formed directly as a circular, downwardly directed depression in the sink bottom 2 of the kitchen sink.
  • a circular outlet area 3 which has a central bore 4.
  • six trapezoidal outlets 5 are arranged in the edge region of the circular outlet region 3, which surround the central bore 4 rotationally symmetrical.
  • FIG. 2 shows the cross section of the flushing drain 1 along the line I-I.
  • the axis II represents a rotational axis of symmetry.
  • the depression within the sink bottom 2, which forms the flush outlet 1 can be clearly seen.
  • two of the trapezoidal outlets 5 are visible here, in the middle of which the central bore 4 is arranged.
  • a drain plug 6 is shown in Figure 2, which consists of a cap 7 made of corrosion-resistant stainless steel, to which a clamping element 8 made of plastic, a guide pin 9 and a sealing element 10 are attached.
  • the guide pin 9 is inserted into a guide sleeve 11 of a drain fitting 12, which is shown in Figure 3.
  • the guide sleeve 11 in turn is inserted from above into the central bore 4.
  • the drain plug is in the Figure 2 in a sealing position, d. H. Rinse water, which runs down the rinse outlet 1, is prevented by the sealing element 10 - here an elastomeric sealing ring - from flowing out of the trapezoidal outlets 5 in the drain fitting 12, since the sealing ring 10 rests in the edge region of the outlet 3 and this effectively seals.
  • Theticianstöpsels 6 is like the Spülenablauf 1 to the rotation axis II rotationally symmetrical, so that the integrally deep-drawn cap 7 of the drain plug in plan view of a circular outer periphery.
  • the pot-shaped Kappenausbuchtung 13 with an upper side 14 and a side wall 15.
  • the open end of the Kappenausbuchtung 13 points down, d. H. on the rinse cycle 1 to.
  • At this Kappenausbuchtung 13 of the drain plug 6 can be gripped from above and lifted out of the guide sleeve 11 vertically.
  • a directed to the axis of rotation II indentation for engagement 16 is provided on the outside of the side wall 15 of the Kappenausbuchtung 13 a directed to the axis of rotation II indentation for engagement 16 is provided. This recess for engagement 16 extends along the entire circumference of the Kappenausbuchtung 13th
  • the clamping element 8 which is disc-shaped, has on its upper side an annular groove 17, which increases its flexibility. Furthermore, in the center of the clamping element 8 is a stepped bore 23.
  • the guide pin 9 is inserted from above into the stepped bore 23 until a helical-like projection 18 of the guide pin 9 comes to rest on the first transverse step of the bore 23 , Instead of connecting the guide pin via this stepped bore 23 with the clamping element 8, it is of course also conceivable that the guide pin 9 is pressed into the clamping element 8.
  • annular strip 19 On the underside of the clamping element 8 is a circumferential annular strip 19, on the outside of an annular groove is recessed, in which the sealing ring 10 is inserted. For this purpose, of course, height and width of the annular groove must correspond to the sealing ring 10.
  • the annular strip 19 is advantageously integrally connected to the clamping element 8.
  • FIG 3 shows the drain plug 6 in section along the line I-I of Figure 1. Further, the drain fitting 12 is shown, which is arranged below the sink outlet 1. Clearly visible here is the basket shape of the cap 7 of the drain plug 6 with the rising in the center of the cap cup-shaped Kappenausbuchtung 13. Furthermore, it can be clearly seen that it is the cap 7 is a strainer, the openings in its peripheral edge region 20th that allow rinse water to pass through them.
  • Figure 4 shows an exploded view of the drain plug 6.
  • the sealing ring 10 is first inserted into the annular groove of the clamping element 8.
  • the guide pin 9 is then inserted into the clamping element 8 until the screw-head Approach 18 of the guide member 9 comes to rest on the transverse step of the bore 23.
  • clamping element 8 and guide pin 9 and the sealing ring 10 is then pressed into the cup-shaped Kappenausbuchtung 13 of the cap 7 of the drain plug 6.
