Definitions

  • the invention relates in particular to a drain plug for a drain fitting a kitchen sink, with a cap, a sealing element and a guide pin aligned parallel to the central axis, wherein both the sealing element and the guide pin below the Top of the cap are arranged.
  • Such drain plugs are used in particular in kitchen sinks, to close the drain in the bottom of a sink, so that water can be collected inside the sink can. Dishes can then be placed in the sink, which is filled with water or food such as salads or fruit can be conveniently cleaned.
  • the drain plug To prevent the drain plug from tilting, its guide pin is attached from above inserted into a corresponding guide sleeve of the drain fitting.
  • a user can change the vertical position of the drain plug change by operating a usually outside the sink arranged lever of a device not described here.
  • the drain plug is removed by a guide pin sealing position, in which the sealing element the drain against leakage the flushing water closes, brought into an open position, the drainage of the water is permitted.
  • the other way round, the drain plug from the open to the sealing position bring.
  • Drain plugs are also known in the prior art, in which the Cap is basket-shaped with a circular, flat cap bottom and an adjoining one, curved upwards running cap rim. This edge of the cap has openings, what further is explained below.
  • Such a drain plug is generally located in a drain compared to the rest of the bottom of the sink, so that it is with its usually circular outer edge on the wall of the process.
  • the Drain plugs both in the sealing and in the open position remain within the drain, as the rinse water is in the open Position can flow through the openings.
  • the ones with openings provided cap also serves as a sieve in which, for example Discard any food residues that have collected in the rinse water. By lifting the drain plug vertically out of the drain these food residues can be conveniently disposed of if necessary.
  • A is usually used to connect the guide pin to the cap end pin of the guide pin from the underside of the cap inserted through a central through hole in the cap base.
  • the length of the pin is such that a large part of the same on the top comes out of the through hole.
  • the diameter of the Pin is smaller than the diameter of the rest of the guide pin, so that a step is formed, which abuts the bottom of the cap from below. At the end of the pin that emerges from the top, it now becomes the axial Fixing the guide pin a fixing cap, for example, by pressure welding attached.
  • the fastening of the sealing element it is known to be a Provide fixing washer, which has a circumferential annular groove in the annular sealing element can be inserted.
  • the fixing washer in turn it is attached to the bottom of the cap.
  • the Locking washer just like the cap base with the guide pin pin corresponding through hole on that of the pin is penetrated before it is inserted through the through hole.
  • the axial fixation of the three parts, i.e. the cap, of the guide pin and the fixing washer is also here with a with the guide pin pin Fixing cap connected by pressure welding.
  • the present invention is therefore based on the task described Disadvantages of the drain plugs known in the prior art avoid, especially the connection of the guide pin and the Simplify the sealing element with the cap, so that in particular the Number of difficult-to-clean columns is reduced, in which bacteria or can collect moisture.
  • the guide pin is advantageously removed from the inner wall of the cap applied pressure held in the cap bulge.
  • the guide pin is therefore oversized compared to the smallest inside diameter the cap bulge made and pressed into what represents a simple, inexpensive connection method.
  • the guide pin diameter should be kept as small as possible so that the cross section of the drain fitting through which Waste water flows as large as possible. Because the guide pin in the guide sleeve the drain fitting sits, but ultimately it reduces the cross section.
  • the guide pin is at one end has a screw head-like approach with which it is in a stepped Bore of the clamping element sits. Then the guide pin when assembling, simply from above into the stepped bore of the Clamping element are used.
  • the clamping element can also be captive in the locking means Cap bulge must be locked. It is particularly favorable that the Assembly of the clamping element and cap later, d. H. in certain circumstances can even be done by the customer.
  • the shape of the clamping element it can be advantageous be disc-shaped with a central bore for receiving of the guide pin.
  • the Wall of the cap bulge is essentially hollow cylindrical, so that the disc-shaped clamping element over its entire circumference lies against the inner wall of the cap bulge, which is optimal radial fixation of the clamping element guaranteed.
  • the upper side of the disk-shaped clamping element can advantageously be have a circumferential annular groove. Through this ring groove a certain flexibility of the upstanding edge of the clamping element achieved what is initially the insertion of the clamping element in the cap bulge can ease.
  • the clamping element is made of plastic, so that it due to its comparatively low weight, the total mass of the drain plug only slightly increased. Furthermore, a clamping element is made Plastic not susceptible to corrosion and also as an injection molded part easy to manufacture.
  • the sealing element it is beneficial if it is on the Clamping element is arranged. Especially when the clamping element is out Plastic is made, it is appropriate to fixtures on the clamping element to be provided by which the sealing element is held there becomes.
  • ring groove it is advantageous if it is in the outer circumference a ring bar arranged at the bottom of the clamping element is.
  • the wall of the cap bulge has on the outside at least one facing the central axis Indentation to intervene on.
  • the drain plug on this indentation the side wall comfortably.
  • this indentation enables the stopper to be gripped securely.
  • the indentation can advantageously be along the entire circumference of the cap bulge. This makes a rotationally symmetrical Indentation that allows the user to To take the stopper on the indentation with one hand without directly To have to look at this.
  • the cap with the bulge formed thereon can advantageously be deep-drawn in one piece so that welds or the like Connection techniques can be avoided.
  • the cap is made of corrosion-resistant Stainless steel.
  • FIG. 1 shows a top view of a circular sink drain 1 Kitchen sink. Since it is with the sink drain, as with the sink itself, is a common component, it will be briefly below - understandable - described.
  • the sink drain 1 is directly as a circular, downward depression molded into the sink floor 2 of the kitchen sink.
  • a circular outlet area 3 in the middle of the sink outlet 1, which has a central bore 4.
  • six trapezoidal outlets 5 arranged, which surround the central bore 4 rotationally symmetrically.
  • Figure 2 shows the cross section of the sink drain 1 along the line I-I.
  • the Axis II represents an axis of rotational symmetry Deepening within the sink floor 2, which forms the sink drain 1. Furthermore, two of the trapezoidal outlets 5 are visible in their The central bore 4 is arranged in the middle.
  • a drain plug 6 is shown in Figure 2, which consists of a Cap 7 is made of corrosion-resistant stainless steel, on the one Clamping element 8 made of plastic, a guide pin 9 and a sealing element 10 are attached.
  • the guide pin 9 is in a guide sleeve 11 of a drain fitting 12, which is shown in Figure 3, inserted.
  • the guide sleeve 11 in turn is inserted into the central bore 4 from above.
  • the drain plug is in a sealing position in FIG. 2, d. H. Flushing water that runs down the flushing drain 1 is through the sealing element 10 - here an elastomer sealing ring - prevented from to flow the trapezoidal outlets 5 into the drain fitting 12 because the sealing ring 10 rests in the edge area of the outlet area 3 and this effectively seals.
  • the drain plug 6, like the sink drain 1, is rotationally symmetrical to the axis of rotation II, so that the one-piece deep-drawn cap 7 of the drain plug has a circular outer circumference in plan view.
  • the cup-shaped cap bulge 13 with an upper side 14 can be seen and a side wall 15.
  • the open end of the cap bulge 13 points downwards, d. H. towards the sink drain 1.
  • the drain plug 6 can be gripped from above and out the guide sleeve 11 are lifted vertically.
  • This grasping to facilitate is on the outside of the side wall 15 of the cap bulge 13 an indentation directed towards the axis of rotation II for engagement 16 provided. This indentation for engaging 16 runs along of the entire circumference of the cap bulge 13.
  • the clamping element 8 which is disc-shaped, has on it Top of an annular groove 17, which increases its flexibility. Still located there is a stepped bore 23 in the center of the clamping element 8.
  • the guide pin 9 is in from above the stepped bore 23 inserted until a screw head-like approach 18 of the guide pin 9 on the first transverse step of the bore 23 comes to lie. Instead of the guide pin over this stepped bore 23 to connect with the clamping element 8, it is of course also conceivable that the guide pin 9 is pressed into the clamping element 8.
  • FIG 3 shows the drain plug 6 in section along the line I-I of the figure 1. Furthermore, the drain fitting 12 is shown, which is below the Sink drain 1 is arranged.
  • the basket shape of the is clearly visible here Cap 7 of the drain plug 6 with the rising in the center of the cap pot-shaped cap bulge 13. Furthermore, it can be clearly seen that it is in the cap 7 is a strainer, which in his circumferential edge region has openings 20 that allow that rinse water passes through them.
  • the sealing ring 10 is not more in sealing system, so that passing through the openings 20 Water directly through the trapezoidal outlets 5 into the drain fitting 12 flows.
  • Figure 4 shows an exploded view of the drain plug 6.
  • the Assembly is first the sealing ring 10 in the annular groove of the clamping element 8 inserted.
  • the stepped bore 23 is then the Guide pin 9 inserted into the clamping element 8 until the screw head-like Approach 18 of the guide element 9 on the transverse step of the bore 23 comes to rest.
  • clamping element 8 and guide pin 9 and the Sealing ring 10 is then in the cup-shaped cap bulge 13th the cap 7 of the drain plug 6 is pressed.
  • a circumferential recess 24 of the clamping element is only slightly recognizable 8, into which a corresponding curvature of the side wall 15 the cap bulge 13 engages.
