Definitions

• the invention relates to a drain fitting for sinks, wash basins, bathtubs or similar sanitary apparatuses with a drain cup held in a drain hole in which a plunger consisting of a guide element and a plunger head as a closure member for the drain hole can be moved longitudinally via a plunger rod is, the upper edge region of the goblet forming a sealing collar for the plunger head in its closed position.
• a generic waste set results, for example, from DE-OS 26 22 182;
• the seat of the drain cup is arranged in the upper region of the drain hole of a basin-like depression in a sanitary apparatus. partially the upper edge of the drain elk forms the upper edge of the drain hole, so that when the plunger head is closed, it sits on the drain cup and closes the drain hole.
• the plunger head in its open position projects beyond the upper edge of the drain hole into the sanitary apparatus, for example, which is designed as a basin.
• the drain fitting which generally consists of chromed or differently colored parts, forms an optical break in the design of the overall object; this applies in particular to the plunger head and the sealing collar of the drain cup.
• the invention is therefore based on the object of improving a generic waste set in such a way that cleaning of the sanitary apparatus, in particular in the region of its drain hole, is facilitated and can be carried out effectively and the optical design of the waste set inserted in the drain hole is improved.
• the solution to this problem results from the main claim; advantageous refinements and developments of the invention are specified in the subclaims.
• the invention includes the basic idea that the seat of the drainage cup in the drainage hole is laid so deep into the wall of the apparatus that the surface of the plunger head forms a plane with the upper edge of the drainage hole in its open position, with the inside being covered visually the diameter of the plunger head is at least as large as the largest diameter of the upper edge area of the drain cup.
• a drain fitting for a thin-walled sink made of metal or plastic is already known, in which the surface of the plunger head forms a plane with the upper edge of the drain hole in its open position.
• the sealing collar cooperating with the plunger head in the closed position of the set is laid in the interior of the drain cup, so that when the drain set is closed, the plunger head is immersed in the drain cup until it rests on a sealing collar specially formed in the drain cup.
• the drain goblet must have a special and complicated shape, because on the one hand it has an upper holder in the drain hole of the sink and on the other hand it has to have an additional sealing design in its interior to interact with the plunger head .
• a further disadvantage is that the drain goblet is clearly visible both in the open and in particular in the closed position of the drain fitting, so that there is an optical break in the design of the sanitary apparatus.
• the design according to the invention has the advantage that the plunger in the Open position no longer protrudes into the basin of the sanitary apparatus and is a hindrance, but forms a line with the contour of the basin, so that the basin can be wiped out easily and without obstruction.
• the plunger head decreases by the amount of movement of the plunger head as a seal on the upper edge area of the drain cup, which is countersunk into the drain hole, the dimensions of the plunger head and drain cup on the one hand and the upper diameter of the drain hole in conjunction with the wall thickness of the sanitary apparatuses, on the other hand, are coordinated with one another in such a way that when the plunger is open there is a sufficient annular gap for the outflow of the water.
• the diameter of the plunger head is at least as large as the largest diameter of the upper edge region of the drain goblet, the plunger head covers the upper edge region or the sealing collar of the drain goblet both in the open and in the closed position, so that a optical unit in the top view of the sanitary apparatus results.
• the drainage cup can thus be chrome-plated in a conventional manner in an advantageous manner and can therefore be used as a relatively inexpensive mass article.
• the plunger head is made of the same material as the sanitary apparatus
• the arrangement of the drain fitting according to the invention means an improvement in the appearance not only with regard to harmonious lines but also with regard to the overall view, because now also the plunger head made of the same material fits into the structure optically clean, leaving the annular gap free for the water drainage. It is advantageous according to the invention to adapt the surface of the plunger head to the lines of the basin contour of the sanitary apparatus in the region of the drain hole, so that the surface of the plunger head need not necessarily be flat. If the surface of the plunger head is convex, as can often be gathered from the prior art, care must be taken that the uppermost partial surface of the plunger head fits into the basin level.
• the invention can also be advantageously implemented if the plunger head is designed as a disk with parallel planes in a manner already resulting from FR 1 296 040; finally, the surface of the plunger head can also be concave according to an embodiment of the invention as a continuation of the lines of the basin wall in the area of the drain fitting, as can be seen in principle from GB 426 851.
• the outer edge of the plunger head and the upper edge of the drain hole are designed in accordance with the outer contour or the inner contour of the upper basin edge of the sanitary apparatus, so that an in results in approximately parallel lines of the assigned boundary lines of the plunger head and pool edge, which improves the overall visual impression.
• the invention can also be advantageously implemented in that the plunger head corresponding to the shape, color and material of the invention is designed as a separate component and can be connected to the head of a conventional plunger, only the upper edge of the drainage cup forming the sealing collar being in its
• the overall dimension of the plunger head composed of the conventional plunger head and the plunger head according to the invention has to be taken into account.
• the plunger head according to the invention is expediently to be connected to the conventional plunger head in a releasable snap-in connection.
• FIG. 1 shows a wash basin in section with the drain set open
• FIG. 2 shows the subject of FIG. 1 with the plunger closed
• Figure 3 shows a washstand in a plan view.
• a drain hole 11 is formed, in which a drain cup 12 with a seat surface 13 is inserted in a watertight manner.
• the inner upper edge region 14 of the drain cup 12 tapers conically and forms a sealing collar for a plunger head 15 of a plunger 16, which is arranged in a longitudinally movable manner via a guide element 17 in the drain cup 12 and is connected to a plug rod 18 via which the longitudinal movement of the guide element 17 is brought between the open position of the plunger head 15 and its closed position with the aid of a pull rod 22.
• annular seal 19 provided on the underside of the plunger head 15 ensures in the closed position of the plunger head 15 that the plunger head rests on the sealing collar 14 of the drainage cup 12 in a sealing manner.
• the surface of the lung head 15, which is formed as a flat disk in the embodiment shown, forms a plane with the wall of the washstand 10, and an annular gap 20 remains at the bottom of the washstand 10, through which the water can enter the goblet 12.
• FIG. 2 accordingly shows the closed position of the plunger head 15, in which the plunger head has sunk into the drain hole 11 until it sits on the sealing collar 14.
• the edge 21 of the drain hole 11 of the body must be glazed in order to provide a perfect look in the positions of the plunger 16.
• the plunger head 15 also consists of ceramic, is glazed in the color of the washbasin 10 and has a diameter that corresponds at least to the largest diameter of the upper edge region 14 of the drain bowl 12, which is therefore practically invisible is.
• FIG. 3 shows an embodiment of the invention, in which the outer edge 23 of the plunger head 15 and the upper edge of the drain cup 11 are designed in accordance with the outer contour 23 or the inner contour 24 of the upper edge of the basin of the sanitary apparatus 10. It becomes parallel in itself
• the outer contour 23 of the upper pool edge can also have a different shape than the inner contour
• Edge 22 of the plunger head 15 optionally the shape of the outer contour 23 or inner contour 24 of the then can correspond to different training of the pool edge.
