Definitions
- the invention relates to a drain fitting for sanitary appliances such as sinks, vanities or bathtubs, with a drain cup held in a drain hole and with a fixed disc inserted into the drain hole, wherein in the drain cup a plunger consisting of a guide element and a plunger head as a closure member for the drain hole is arranged such that the plunger head can be moved between a closed position and an open position below the fixed disk.
- a drain set of the aforementioned type is known from FR-A-1 543 952; this drain fitting has a drain goblet which, with an encircling, horizontally protruding edge which is inserted into an adapted gradation in the wall of the drain hole of the sanitary apparatus, forms a support for a disc lying thereon and completely filling the opening of the drain hole.
- This disc is designed to be continuously perforated for the production of a drain for the water and therefore serves to retain foreign bodies, in particular waste, from the draining water.
- a conventional plunger with a plunger head which interacts with the drain cup as a closure member, is arranged below the disk in a movable manner between an open position and a closed position.
- the disadvantage of the known drain fitting is that the fixed perforated disc allows a view of the plunger which is movable below the disc, so that the optical design of this drain fitting does not meet the usual requirements, particularly in the bathroom area.
- Another waste set with a fixed disc is known from AT-B-375 988; here the actual waste set with plunger is arranged outside the sanitary apparatus; in the drain hole of the sanitary apparatus, a drain sleeve with an upper edge area is inserted, into which a fixed disk is inserted to form an annular gap for the water flowing off; however, this fixed disk does not cover the drain sleeve, so that there is also a visual disadvantage here.
- the invention is therefore based on the object to improve the overall visual impression in a generic waste set using a conventional plunger; the drain set should be inexpensive to manufacture.
- the basic idea of the invention provides that the upper edge region of the drain cup forms a sealing collar for the plunger head in its closed position and this upper edge region with its seat surface is inserted deep into the wall of the sanitary apparatus to form a space for the longitudinal movement of the plunger head and that the fixed disc from one Ceramic part with a color matching the colored ceramic material of the sanitary apparatus and has a diameter which is smaller than the diameter of the drain hole and at least as large as the largest diameter of the upper edge region of the drain cup, so that between the edge of the drain hole and the fixed disc remaining annular gap corresponds to the flow specifications of known drain fittings.
- a drain fitting is also known in which the plunger head already has a diameter which is at least as large as the largest diameter of the upper edge region of the drain goblet, but this has the disadvantage that the plunger head itself in its The color and shape must be completely matched to the associated sanitary apparatus, so that drain fittings to be associated with different sanitary apparatuses must each have a differently manufactured plunger head. This means that conventional plungers cannot be used without special adaptation to the appearance of the sanitary apparatus.
- the invention is essentially associated with the advantage that the plunger head, which is hidden by the disk fixed in the drain hole, can be made of any material and in a simple design, since it is not visible at any time.
- the fixed disc is easy to manufacture in terms of material, shape and color, specifically to adapt to the sanitary apparatus, with either the standardized waste set to adapt it to the respective sanitary apparatus simply a disc to be inserted into the drain hole of the sanitary apparatus after Invention is to be attached. Since the diameter of the disc is at least as large as the largest diameter of the upper edge area of the drain cup of the drain fitting, not only the plunger head, but also the upper edge area of the drain cup serving as a seat is completely covered.
- an exemplary embodiment of the invention provides for the disc to be inserted into the drain hole with the feet arranged on its outer circumference, the feet being supported on the narrowing wall of the drain hole in the sanitary apparatus. It is particularly advantageous here if the inwardly shifted feet are supported on the upper edge of the goblet, at which point there is the possibility of the material transfer between the drain fitting and the sanitary apparatus for attaching appropriate form-fitting designs.
- Such a design has the advantage that the feet are also arranged under the pane and are therefore not visible.
- Another possibility of securing the disk against displacement is to arrange a guide rod on its underside, which in turn engages in a channel arranged in the plunger; here a game is provided that on the one hand the plunger head is displaceable with respect to the disk during its opening and closing movement, but that on the other hand there is a security against slipping of the disk in the drain hole.
- This measure can either be used alone to secure the disk, or else in combination with an additional support by means of feet and / or projections to be provided accordingly.
- the surface of the pane should line up adapt the apparatus in the area of the drain hole, various shapes, such as a concave surface of the disk, or a configuration with parallel planes, being useful for this purpose.
- a drain hole 11 is formed, in which a drain cup 12 with a seat surface 13 is inserted in a watertight manner.
- the inside upper edge region 14 of the drain cup 12 tapers and forms a sealing collar 14 'for a plunger head 15 of a plunger 16 which is arranged to be longitudinally movable via guide elements 17 in the drain cup 12 and is connected to a plunger rod 18 via which the longitudinal movement of the guide elements 17 between the open position of the plunger head 15 and its closed position is brought about with the aid of a pull rod 22.
- a provided on the underside of the plunger head 15 ring seal 19 ensures in the closed position of the plunger head 15 for a sealing seat of the plunger head on the sealing collar 14 'of the drain bowl 12th
- a fixed disc 25 is arranged, which is inserted into the drain hole 11 by means of three feet 26 arranged on its outer circumference so that the feet 26 stand on the upper edge 14 'of the drain cup 12.
- the diameter of the disc 25 is chosen relative to the diameter of the drain hole 11 so that there is a constantly open annular gap 20 through which the water can flow out of the sanitary apparatus.
- the drain cup 12 is so far into the wall of the apparatus 10 that the plunger head 15 can be moved between its open and closed positions without the disk 25 arranged in the plane of the drain hole 11 to change their position.
- the disk 25 not only covers the plunger head 15, but also the upper edge region 14 ⁇ of the drain bowl 12. Since the feet 26 stand on the upper edge 14 of the drain bowl 12, they are also covered by the disk 25.
- the feet or the upper edge of the drain cup have corresponding positive connections in order to fix the disk 25 in the drain hole; in this case 12 openings could be formed in the upper edge 14 ⁇ of the drain bowl, into which the disk 25 with feet 26 can be inserted by means of a snap fit.
- FIG. 3 shows a further exemplary embodiment of the invention with regard to the fixing of the disk 25, in that a rod 28 is provided on the underside thereof, which engages in an assigned channel 29 in the plunger 16; the channel 29 and the rod 28 are dimensioned so that there is a smooth guidance of the plunger head 15 relative to the fixed disc 25; on the other hand, the disk 25 is secured against displacement relative to the plunger head.
- This measure can be used both alone and in combination with other supports.

Abstract
Description
Die Erfindung betrifft eine Ablaufgarnitur für sanitäre Apparate wie Spülbecken, Waschtische oder Badewannen, mit einem in einem Ablaufloch gehalterten Ablaufkelch und mit einer in das Ablaufloch eingesetzten feststehenden Scheibe, wobei in dem Ablaufkelch ein aus einem Führungselement und einem Plungerkopf als Verschlußglied für das Ablaufloch bestehender Plunger derart angeordnet ist, daß der Plungerkopf zwischen einer Schließstellung und einer Öffnungsstellung unterhalb der feststehenden Scheibe bewegbar ist.The invention relates to a drain fitting for sanitary appliances such as sinks, vanities or bathtubs, with a drain cup held in a drain hole and with a fixed disc inserted into the drain hole, wherein in the drain cup a plunger consisting of a guide element and a plunger head as a closure member for the drain hole is arranged such that the plunger head can be moved between a closed position and an open position below the fixed disk.
Eine Ablaufgarnitur der vorgenannten Gattung ist aus der FR-A-1 543 952 bekannt; diese Ablaufgarnitur weist einen Ablaufkelch auf, der mit einem umlaufenden, waagerecht abstehenden und in eine angepaßte Abstufung in der Wandung des Ablaufloches des sanitären Apparates eingesetzten Rand eine Auflage für eine darauf aufliegende und die Öffnung des Ablaufloches vollständig ausfüllende Scheibe ausbildet. Diese Scheibe ist zur Herstellung einer Abflußmöglichkeit für das Wasser durchgehend gelocht ausgebildet und dient daher dem Zurückhalten von Fremdkörpern, insbesondere Abfällen, aus dem abfließenden Wasser. Unterhalb der Scheibe ist in dem Ablaufkelch ein üblicher Plunger mit einem mit dem Ablaufkelch als Verschlußglied zusammenwirkenden Plungerkopf zwischen einer Öffnungsstellung und einer Schließstellung beweglich angeordnet.A drain set of the aforementioned type is known from FR-A-1 543 952; this drain fitting has a drain goblet which, with an encircling, horizontally protruding edge which is inserted into an adapted gradation in the wall of the drain hole of the sanitary apparatus, forms a support for a disc lying thereon and completely filling the opening of the drain hole. This disc is designed to be continuously perforated for the production of a drain for the water and therefore serves to retain foreign bodies, in particular waste, from the draining water. A conventional plunger with a plunger head, which interacts with the drain cup as a closure member, is arranged below the disk in a movable manner between an open position and a closed position.
Mit der bekannten Ablaufgarnitur ist der Nachteil verbunden, daß die feststehende gelochte Scheibe einen Durchblick auf den unterhalb der Scheibe beweglichen Plunger erlaubt, so daß die optische Ausgestaltung dieser Ablaufgarnitur den üblichen Ansprüchen insbesondere im Badezimmerbereich nicht genügt.The disadvantage of the known drain fitting is that the fixed perforated disc allows a view of the plunger which is movable below the disc, so that the optical design of this drain fitting does not meet the usual requirements, particularly in the bathroom area.
Eine weitere Ablaufgarnitur mit einer feststehenden Scheibe ist aus der AT-B-375 988 bekannt; hier ist die eigentliche Ablaufgarnitur mit Plunger außerhalb des sanitären Apparates angeordnet; in das Ablaufloch des sanitären Apparates ist eine Ablaufhülse mit einem oberen Randbereich eingesetzt, in die unter Ausbildung eines Ringspaltes für das abfließende Wasser eine feststehende Scheibe eingesetzt ist; diese feststehende Scheibe verdeckt jedoch die Ablaufhülse nicht, so daß auch hier ein optischer Nachteil vorhanden ist.Another waste set with a fixed disc is known from AT-B-375 988; here the actual waste set with plunger is arranged outside the sanitary apparatus; in the drain hole of the sanitary apparatus, a drain sleeve with an upper edge area is inserted, into which a fixed disk is inserted to form an annular gap for the water flowing off; however, this fixed disk does not cover the drain sleeve, so that there is also a visual disadvantage here.
Der Erfindung liegt daher die Aufgabe zugrunde, bei einer gattungsgemäßen Ablaufgarnitur unter Verwendung eines üblichen Plungers den optischen Gesamteindruck zu verbessern; dabei soll die Ablaufgarnitur preiswert herstellbar sein.The invention is therefore based on the object to improve the overall visual impression in a generic waste set using a conventional plunger; the drain set should be inexpensive to manufacture.
Die Lösung dieser Aufgabe ergibt sich aus dem Hauptanspruch; vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.The solution to this problem results from the main claim; advantageous refinements and developments of the invention are specified in the subclaims.
Die Erfindung sieht in ihrem Grundgedanken vor, daß der obere Randbereich des Ablaufkelches einen Dichtkragen für den Plungerkopf in dessen Schließstellung ausbildet und dieser obere Randbereich mit seiner Sitzfläche zur Ausbildung eines Spielraumes für die Längsbewegung des Plungerkopfes tief in die Wandung des sanitären Apparates eingesetzt ist und daß die feststehende Scheibe aus einem Keramikteil mit einer dem farbigen keramischen Material des sanitären Apparates angepaßten Farbgebung besteht und einen Durchmesser aufweist, der kleiner als der Durchmesser des Ablaufloches und mindestens so groß wie der größte Durchmesser des oberen Randbereiches des Ablaufkelches ist, so daß der zwischen dem Rand des Ablaufloches und der feststehenden Scheibe verbleibende Ringspalt den Durchflußvorgaben bekannter Ablaufgarnituren entspricht.The basic idea of the invention provides that the upper edge region of the drain cup forms a sealing collar for the plunger head in its closed position and this upper edge region with its seat surface is inserted deep into the wall of the sanitary apparatus to form a space for the longitudinal movement of the plunger head and that the fixed disc from one Ceramic part with a color matching the colored ceramic material of the sanitary apparatus and has a diameter which is smaller than the diameter of the drain hole and at least as large as the largest diameter of the upper edge region of the drain cup, so that between the edge of the drain hole and the fixed disc remaining annular gap corresponds to the flow specifications of known drain fittings.
Aus der DE 39 09 651 C1 ist ferner eine Ablaufgarnitur bekannt, bei der der Plungerkopf bereits einen Durchmesser aufweist, der mindestens so groß ist wie der größte Durchmesser des oberen Randbereiches des Ablaufkelches, jedoch ist damit der Nachteil verbunden, daß der Plungerkopf selbst in seiner Farb- und Formgebung jeweils vollständig auf den zugeordneten sanitären Apparat abgestimmt sein muß, so daß jeweils verschiedenen sanitären Apparaten zuzuordnende Ablaufgarnituren jeweils einen unterschiedlich gefertigten Plungerkopf aufweisen müssen. Damit sind übliche Plunger ohne eine besondere Anpassung an die Optik des sanitären Apparates nicht zu verwenden.From DE 39 09 651 C1 a drain fitting is also known in which the plunger head already has a diameter which is at least as large as the largest diameter of the upper edge region of the drain goblet, but this has the disadvantage that the plunger head itself in its The color and shape must be completely matched to the associated sanitary apparatus, so that drain fittings to be associated with different sanitary apparatuses must each have a differently manufactured plunger head. This means that conventional plungers cannot be used without special adaptation to the appearance of the sanitary apparatus.
Mit der Erfindung ist im wesentlichen der Vorteil verbunden, daß der durch die im Ablaufloch feststehende Scheibe verdeckte Plungerkopf aus beliebigen Materialien und in einfacher Ausführung ausgestaltet sein kann, da er zu keinem Zeitpunkt sichtbar ist. Die feststehende Scheibe ist dabei nach Material sowie Form- und Farbgebung einfach herzustellen, und zwar in Anpassung an den sanitären Apparat, wobei wahlweise der standardisierten Ablaufgarnitur zu deren Anpassung an den jeweiligen sanitären Apparat lediglich eine Scheibe zum Einsetzen in das Ablaufloch des sanitären Apparates nach der Erfindung beizufügen ist. Da der Durchmesser der Scheibe mindestens so groß ist wie der größte Durchmesser des oberen Randbereiches des Ablaufkelches der Ablaufgarnitur, ist nicht nur der Plungerkopf, sondern auch der als Sitz dienende obere Randbereich des Ablaufkelches völlig verdeckt.The invention is essentially associated with the advantage that the plunger head, which is hidden by the disk fixed in the drain hole, can be made of any material and in a simple design, since it is not visible at any time. The fixed disc is easy to manufacture in terms of material, shape and color, specifically to adapt to the sanitary apparatus, with either the standardized waste set to adapt it to the respective sanitary apparatus simply a disc to be inserted into the drain hole of the sanitary apparatus after Invention is to be attached. Since the diameter of the disc is at least as large as the largest diameter of the upper edge area of the drain cup of the drain fitting, not only the plunger head, but also the upper edge area of the drain cup serving as a seat is completely covered.
Um der im Ablaufloch anzuordnenden feststehenden Scheibe einen festen Sitz in dem Ablaufloch zu geben, damit diese insbesondere beim Reinigen beziehungsweise Auswischen des sanitären Apparates ihre Lage beibehält, ist nach Ausführungsbeispielen der Erfindung vorgesehen, entsprechende Formschluß- oder Führungsgestaltungen anzuordnen, um insoweit den festen Sitz der Scheibe im Ablaufloch zu gewährleisten. Hierzu sieht ein Ausführungsbeispiel der Erfindung vor, die Scheibe mit an ihrem äußeren Umfang angeordneten Füßchen in das Ablaufloch einzusetzen, wobei sich die Füßchen an der sich verengenden Wandung des Ablaufloches in dem sanitären Apparat abstützen. Hierbei ist es besonders vorteilhaft, wenn die nach innen verlagerten Füßchen sich auf dem oberen Rand des Ablaufkelches abstützen, wobei an dieser Stelle die Möglichkeit besteht, den Materialübergang zwischen Ablaufgarnitur und sanitärem Apparat zur Anbringung entsprechender Formschlußgestaltungen auszunutzen. Mit einer derartigen Gestaltung ist der Vorteil verbunden, daß auch die Füßchen unter der Scheibe angeordnet und mithin nicht sichtbar sind.In order to give the fixed disc to be arranged in the drain hole a firm fit in the drain hole so that it maintains its position, in particular when cleaning or wiping the sanitary apparatus, according to exemplary embodiments of the invention it is provided to arrange corresponding form-fitting or guide designs so that the tight fit of the Ensure disc in the drain hole. For this purpose, an exemplary embodiment of the invention provides for the disc to be inserted into the drain hole with the feet arranged on its outer circumference, the feet being supported on the narrowing wall of the drain hole in the sanitary apparatus. It is particularly advantageous here if the inwardly shifted feet are supported on the upper edge of the goblet, at which point there is the possibility of the material transfer between the drain fitting and the sanitary apparatus for attaching appropriate form-fitting designs. Such a design has the advantage that the feet are also arranged under the pane and are therefore not visible.
Eine weitere Möglichkeit der Sicherung der Scheibe gegen Verschieben besteht darin, an ihrer Unterseite eine Führungsstange anzuordnen, die ihrerseits in einen in dem Plunger angeordneten Kanal eingreift; hierbei ist ein Spiel vorgesehen, daß einerseits der Plungerkopf bei seiner Öffnungs- und Schließbewegung gegenüber der Scheibe verschiebbar ist, daß andererseits aber eine Sicherung gegen Verrutschen der Scheibe im Ablaufloch gegeben ist. Diese Maßnahme kann entweder alleine zur Sicherung der Scheibe verwendet werden, oder aber auch in Kombination mit einer zusätzlichen Abstützung über entsprechend vorzusehende Füßchen und/oder Vorsprünge.Another possibility of securing the disk against displacement is to arrange a guide rod on its underside, which in turn engages in a channel arranged in the plunger; here a game is provided that on the one hand the plunger head is displaceable with respect to the disk during its opening and closing movement, but that on the other hand there is a security against slipping of the disk in the drain hole. This measure can either be used alone to secure the disk, or else in combination with an additional support by means of feet and / or projections to be provided accordingly.
Die Verwendung einer genormten Ablaufgarnitur bezieht sich im Zusammenhang mit der Erfindung auf die Abmessungen und die jeweilige Zuordnung der Funktionsteile zueinander. Im Hinblick auf die Halterung der erfindungsgemäßen Scheibe im Ablaufloch können auch außerhalb der Funktion der Ablaufgarnitur liegende bauliche Anpassungen verwirklicht sein.The use of a standardized waste set relates in connection with the invention to the dimensions and the respective assignment of the functional parts to one another. With regard to the mounting of the disc according to the invention in the drain hole, structural adjustments lying outside the function of the drain set can also be implemented.
Im übrigen soll sich die Scheibe mit ihrer Oberfläche der Linienführung des Apparates im Bereich des Ablaufloches anpassen, wobei hierzu verschiedene Formgebungen, wie eine konkave Oberfläche der Scheibe, oder eine Ausbildung mit parallelen Ebenen, zweckmäßig sein können.For the rest, the surface of the pane should line up adapt the apparatus in the area of the drain hole, various shapes, such as a concave surface of the disk, or a configuration with parallel planes, being useful for this purpose.

Der innenseitige obere Randbereich 14 des Ablaufkelches 12 läuft konisch zu und bildet einen Dichtkragen 14′ für einen Plungerkopf 15 eines Plungers 16 aus, der über Führungselemente 17 in dem Ablaufkelch 12 längsbeweglich angeordnet und mit einer Plungerstange 18 verbunden ist, über welche die Längsbewegung der Führungselemente 17 zwischen der Öffnungsstellung des Plungerkopfes 15 und dessen Schließstellung mit Hilfe einer Zugstange 22 herbeigeführt wird. Eine an der Unterseite des Plungerkopfes 15 vorgesehene Ringdichtung 19 sorgt in der Schließstellung des Plungerkopfes 15 für ein dichtendes Aufsitzen des Plungerkopfes auf dem Dichtkragen 14′ des Ablaufkelches 12.In a
In der Ebene des Ablaufloches 11 ist eine feststehende Scheibe 25 angeordnet, welche mittels dreier auf ihrem äußeren Umfang angeordneter Füßchen 26 in das Ablaufloch 11 so eingesetzt ist, daß die Füßchen 26 auf dem oberen Rand 14˝ des Ablaufkelches 12 aufstehen. Der Durchmesser der Scheibe 25 ist gegenüber dem Durchmesser des Ablaufloches 11 so gewählt, daß sich ein ständig offener Ringspalt 20 ergibt, durch welchen das Wasser aus dem sanitären Apparat abfließen kann.In the plane of the
Wie sich aus einem Vergleich der Figuren 1 und 2 ergibt, ist der Ablaufkelch 12 so weit in die Wandung des Apparates 10 hineinverlegt, daß der Plungerkopf 15 zwischen seiner Öffnungs- und Schließstellung bewegbar ist, ohne die in der Ebene des Ablaufloches 11 angeordnete Scheibe 25 in ihrer Lage zu verändern. Gleichzeitig verdeckt die Scheibe 25 nicht nur den Plungerkopf 15, sondern auch den oberen Randbereich 14˝ des Ablaufkelches 12. Da die Füßchen 26 auf dem oberen Rand 14 des Ablaufkelches 12 aufstehen, sind sie ebenfalls von der Scheibe 25 verdeckt.As can be seen from a comparison of FIGS. 1 and 2, the
Wie weiter dargestellt ist, weisen die Füßchen beziehungsweise der obere Rand des Ablaufkelches entsprechende Formschlußverbindungen auf, um die Scheibe 25 in dem Ablaufloch festzulegen; hierbei könnten in dem oberen Rand 14˝ des Ablaufkelches 12 Öffnungen ausgebildet sein, in die mittels Schnappsitz die Scheibe 25 mit Füßchen 26 einsetzbar ist.As is further shown, the feet or the upper edge of the drain cup have corresponding positive connections in order to fix the
Aus Figur 3 ergibt sich ein weiteres Ausführungsbeispiel der Erfindung im Hinblick auf das Festlegen der Scheibe 25, indem an deren Unterseite eine Stange 28 vorgesehen ist, die in einen zugeordneten Kanal 29 im Plunger 16 eingreift; der Kanal 29 sowie die Stange 28 sind dabei so bemessen, daß eine glatte Führung des Plungerkopfes 15 gegenüber der feststehenden Scheibe 25 gegeben ist; andererseits ist die Scheibe 25 gegenüber dem Plungerkopf gegen Verschieben gesichert. Diese Maßnahme kann sowohl alleine als auch in Kombination mit weiteren Abstützungen Verwendung finden.FIG. 3 shows a further exemplary embodiment of the invention with regard to the fixing of the
