Abstract

A new shower head is intended for handheld and/or fixed shower fitting. Connected to the water supply, its casing (12) forms a chamber with a base section (2). The base section has an outer ring (3) in rubbery, elastic material with grooves (33) to produce the water jets. The ring rests by its outer casing in a reception bore (16). In this novel design, the ring and a collar (30) project downstream beyond the base section which acts as a carrier plate. By scraping or working the collar, limescale deposits in the grooves can be removed. Preferably the base section is plastic, especially polypropylene. The ring element (3) is a thermoplastic elastomer, especially Santoprene (RTM), which is injected onto the base section,

Description

Die Erfindung betrifft einen Brausekopf für eine Hand- und/oder Stationärbrause mit einem an die Wasserzufuhr anschließbaren, wenigstens eine Wasserkammer bildenden Gehäuse und einem Bodenteil, wobei der Bodenteil wenigstens an einem Außenmantelbereich ein aus gummielastischem Werkstoff hergestelltes Ringelement hat, welches am Außenumfang eine Vielzahl von Nuten für die Erzeugung von Brausestrahlen aufweist, wobei das Ringelement mit wenigstens einem Teil seines Außenmantels an einer Aufnahmebohrung anliegt.The invention relates to a shower head for a hand and / or stationary shower head with a housing which can be connected to the water supply and forms at least one water chamber and a base part, the base part having at least on one outer jacket region a ring element made of rubber-elastic material which has a plurality of on the outer circumference Has grooves for the generation of shower jets, wherein the ring element rests with at least a part of its outer jacket on a receiving bore.

Ein derartiger Brausekopf ist beispielsweise aus der US-Patentschrift 3,826,429 bekannt. Bei Brauseköpfen kann es zu Kalkablagerungen im Bereich der brausestrahlbildenden Nuten oder Öffnungen kommen, die die Brausestrahlbildung beeinträchtigen. Diese Kalkablagerungen bzw. Kalkverkrustungen in den Nuten oder Öffnungen werden hauptsächlich dadurch verursacht, daß der am Austrittsbereich einer Öffnung haftende Wassertropfen während der Nichtbenutzung der Brause eintrocknet. Die Kalkkristalle lagern sich dabei jeweils am Austrittsende der Öffnung oder Nut ab und härten, je nach Trocknungszeit, mehr oder weniger stark aus. Durch ein häufiges Wiederholen dieses Eintrocknungsvorganges, wie es nach jedem Duschen am Brausekopf auftritt, kann es zu Störungen bei der Brausestrahlbildung kommen bzw. auch zu einem völligen Verschluß der Nuten oder Öffnungen für die Erzeugung der einzelnen Brausestrahlen führen. Obwohl bei dem Brausekopf nach der US-Patentschrift 3,826,429 das Ringelement an dem aus starrem Werkstoff hergestellten Bodenteil bereits aus einem gummielastischen Werkstoff hergestellt ist, kann es hierbei problematisch sein, die unerwünschten und störenden Kalkverkrustungen zu entfernen.Such a shower head is known, for example, from US Pat. No. 3,826,429. In the case of shower heads, limescale deposits can form in the area of the shower jet-forming grooves or openings, which impair the shower jet formation. These limescale deposits or lime incrustations in the grooves or openings are mainly caused by the fact that the water drop adhering to the outlet area of an opening dries out when the shower is not in use. The lime crystals are deposited at the exit end of the opening or groove and harden, depending on the drying time, to a greater or lesser extent. Frequent repetition of this drying process, as occurs after every shower at the shower head, can lead to malfunctions in the spray jet formation or even to a complete occlusion of the grooves or openings for the generation of the individual spray jets. Although in the shower head according to US Pat. No. 3,826,429 the ring element on the base part made of rigid material is already made of a rubber-elastic material, it can be problematic in this case to remove the undesirable and disruptive scale deposits.

Der Erfindung liegt deshalb die Aufgabe zugrunde, den im Oberbegriff des Anspruchs 1 angegebenen Brausekopf zu verbessern, so daß die sich in den Nuten des Brausekopfes bildenden Verkrustungen relativ leicht vom Brausebenutzer entfernt werden können.The invention is therefore based on the object of improving the shower head specified in the preamble of claim 1, so that the incrustations formed in the grooves of the shower head can be removed relatively easily by the shower user.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Ringelement mit einem Kragen stromabwärts über den als Trägerplatte wirkenden Bodenteil vorsteht, so daß durch ein Abstreichen oder Walken des Kragens Kalkabscheidungen in den Nuten entfernbar sind.This object is achieved in that the ring element projects with a collar downstream over the base part acting as a support plate, so that limescale deposits in the grooves can be removed by wiping or flexing the collar.

Weitere Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 18 angegeben.
Mit den vorgeschlagenen Maßnahmen wird mit einfachen Mitteln eine Entfernung der sich im wesentlichen am Austrittsende der als Strahlbildner wirkenden Nuten - da in erheblichem Maße nur im Bereich der Umgebungsluft ein Eintrocknen des Brausewassers möglich ist - entstehenden Kalkverkrustungen ermöglicht. Das erfindungsgemäße Ringelement kann sowohl an einem ortsfest im Gehäuse des Brausekopfes angeordneten Bodenteils angeordnet werden als auch an einem Bodenteil, welches axial zum Gehäuse des Brausekopfes bewegbar ist, um beispielsweise das Strahlbild des Brausekopfes zu verändern und/oder den Querschnitt der einzelnen Brausestrahlen zu verändern, so daß beispielsweise unterschiedlich harte Brausestrahlen erzeugt werden können.
Der mit dem Ringelement zusammenwirkende Bohrungsteil des Brausekopfes kann hierbei ebenfalls mit einem gummielastischen Werkstoff ausgekleidet sein.
Auch kann der Bodenteil insgesamt aus einem gummielastischen Werkstoff hergestellt werden, wobei dann der Tragbereich des Bodenteils - um die erforderliche Starrheit aufzuweisen - entsprechend dickwandig ausgebildet ist und/oder aus starrem Werkstoff, wie etwa Metall, hergestellte Tragkörper in dem Bodenteil vorgesehen (einvulkanisiert)werden.Further refinements of the invention are specified in claims 2 to 18.
With the proposed measures, removal of the lime incrustations which occur essentially at the outlet end of the grooves acting as jet formers is made possible with simple means, since it is only possible to dry out the shower water to a considerable extent in the area of the ambient air. The ring element according to the invention can be arranged both on a fixed base part arranged in the housing of the shower head and on a base part which can be moved axially relative to the housing of the shower head, for example in order to change the spray pattern of the shower head and / or to change the cross section of the individual shower jets, so that, for example, shower jets of different hardness can be generated.
The bore part of the shower head which interacts with the ring element can also be lined with a rubber-elastic material.
The base part can also be made entirely of a rubber-elastic material, in which case the supporting area of the base part - in order to have the required rigidity - is correspondingly thick-walled and / or support bodies made of rigid material, such as metal, are provided (vulcanized) in the base part .

Bei dem in Figur 1 dargestellten Ausführungsbeispiel ist ein Brausekopf einer Stationärbrause gezeigt. Der Brausekopf wird dabei im wesentlichen von einem Gehäuse 1 und einem Bodenteil 2 mit einem Ringelement 3 gebildet. Koaxial zur Mittelachse 10 ist am stromaufwärts gelegenen Endbereich des Gehäuses 1 ein Kugelkopf 11 zur stationären Befestigung an einer Wasserversorgungsleitung in einer Gebäudewand (in der Zeichnung nicht dargestellt) vorgesehen. Das zugeführte Brausewasser gelangt durch den Kugelkopf 11 in eine Wasserkammer 12 des Gehäuses 1. Koaxial im Gehäuse 1 ist ein Hohlzylinder 13 ausgebildet, dessen stromaufwärts gelegene Stirnseite verschlossen ist. In der in die Wasserkammer 12 hineinragenden Seitenwand des Hohlzylinders 13 sind Radialöffnungen 130 ausgebildet, durch die das in der Wasserkammer 12 befindliche Wasser in den Hohlzylinder 13 einströmen kann. In dem Hohlzylinder 13 ist ein Hohlkolben 14 axial verschiebbar angeordnet, wobei am stromabwärts gelegenen Endbereich der Bodenteil 2 mit einer Hohlschraube 21, die gleichzeitig eine Düse 210 für die Formung eines Massagestrahls bildet, befestigt. Der Hohlkolben 14 ist dabei mit einem Bewegungsgewinde 141 axial verschiebbar im Gehäuse 1 angeordnet, wobei im Bewegungsgewinde 141 Axialschlitze 1410 für die Wasserdurchführung vorgesehen sind. Für die Axialverstellung des Hohlkolbens 14 im Gehäuse 1 ist außerdem ein Drehring 15 am Gehäuse 1 drehbar befestigt, der andererseits über Rippen 151 mit dem stromabwärts gelegenen Endbereich des Hohlkolbens 14 drehfest verbunden ist. Der Drehring 15 weist außerdem eine Bohrung 16 für die Aufnahme des Außenmantels des Ringelements 3 auf. Er trägt außerdem einen Griffring 152, mit dem der Benutzer die gewünschte Stellung des Hohlkolbens 14 mit dem Bodenteil 2 zum Gehäuse 1 und der Bohrung 16 einstellen kann.In the embodiment shown in Figure 1, a shower head of a stationary shower is shown. The shower head is essentially formed by a housing 1 and a base part 2 with a ring element 3. A spherical head 11 is coaxial to the central axis 10 at the upstream end region of the housing 1 intended for stationary attachment to a water supply line in a building wall (not shown in the drawing). The shower water supplied passes through the ball head 11 into a water chamber 12 of the housing 1. A hollow cylinder 13 is formed coaxially in the housing 1, the upstream end of which is closed. Radial openings 130 are formed in the side wall of the hollow cylinder 13 projecting into the water chamber 12, through which the water in the water chamber 12 can flow into the hollow cylinder 13. A hollow piston 14 is arranged axially displaceably in the hollow cylinder 13, the bottom part 2 being fastened to the downstream end region with a hollow screw 21, which at the same time forms a nozzle 210 for shaping a massage jet. The hollow piston 14 is axially displaceably arranged in the housing 1 with a movement thread 141, wherein in the movement thread 141 axial slots 1410 are provided for the passage of water. For the axial adjustment of the hollow piston 14 in the housing 1, a rotary ring 15 is also rotatably attached to the housing 1, which on the other hand is connected in a rotationally fixed manner to the downstream end region of the hollow piston 14 via ribs 151. The rotary ring 15 also has a bore 16 for receiving the outer shell of the ring element 3. It also carries a grip ring 152 with which the user can set the desired position of the hollow piston 14 with the base part 2 relative to the housing 1 and the bore 16.

Der Bodenteil 2 trägt an seinem Außenmantel das Ringelement 3 aus gummielastischem Werkstoff mit einer Materialhärte von Shore A 35 bis 50. Am Außenmantel des Ringelements 3 sind eine Vielzahl von Nuten 33 angeordnet, deren Grundfläche 310 zur Mittelachse 10 geneigt angeordnet ist. An der stromabwärts gelegenen Stirnseite des Ringelements 3 ist ein umlaufender Kragen 30 ausgebildet, dessen Vorstehlänge 300 zum Bodenteil 2 etwa 2 mm beträgt. Der Kragen 30 ist dabei in Fließrichtung des Wassers konisch verjüngt ausgebildet, so daß die stromabwärts gelegene Wandstärke 301 etwa 0,5 mm beträgt. Die einzelnen Nuten 33 bilden mit der Wandung der Bohrung 16 im Drehring 15 Strahlbildnerdüsen für die einzelnen Brausestrahlen, wobei der Querschnitt der Nuten 33 quadratisch oder rechteckig in Abhängigkeit von der Eintauchtiefe des Brausebodens 2 in den Brausekopf bzw. der Bohrung 16 ist.The base part 2 carries on its outer casing the ring element 3 made of rubber-elastic material with a material hardness of Shore A 35 to 50. A plurality of grooves 33 are arranged on the outer casing of the ring element 3, the base 310 of which is arranged inclined to the central axis 10. A circumferential collar 30 is formed on the downstream end face of the ring element 3, the protruding length 300 of the base part 2 being approximately 2 mm. The collar 30 is tapered in the direction of flow of the water, so that the downstream wall thickness 301 is approximately 0.5 mm. The individual grooves 33 form with the wall of the bore 16 in the rotating ring 15 jet-forming nozzles for the individual shower jets, the cross section of the grooves 33 being square or rectangular depending on the depth of immersion of the shower base 2 in the shower head or the bore 16.

Beim Brausevorgang gelangt das Brausewasser entsprechend der Pfeile 100 über den Kugelkopf 11 in die Wasserkammer 12. In Abhängigkeit von der Axialstellung des Hohlkolbens 14 gelangt das durch die Radialöffnungen 131 in den Hohlzylinder 13 einströmende Wasser entweder zu den Nuten 33 oder in den Hohlkolben 14, wie es in der rechten Bildhälfte der Figur 1 dargestellt ist, und von hier über die Düsenausbildung in der Schraube 21 als einzelner, gebündelt austretender Massagestrahl ins Freie.
Bei der Position des Hohlkolbens 14 in der linken Bildhälfte gelangt das durch die Radialöffnungen 131 in den Hohlzylinder 13 einströmende Wasser über die Axialschlitze 1410 in einen Ringraum oberhalb des Bodenteils 2 und von hier in die einzelnen, über den Außenmantel des Ringelements 3 verteilten Nuten 33 und wird hier als Kranz von einzelnen Brausestrahlen abgegeben. Wird nun der Hohlkolben 14 von seiner in der linken Bildhälfte dargestellten Position durch eine Schraubbewegung mit dem Drehring 15 abgesenkt, so wird im gleichen Maße auch der Bodenteil 2 mit dem Ringelement 3 aus der Bohrung 16 des Drehrings 15 herausgeschoben. Hierdurch wird der Austrittsquerschnitt der Nuten 33 vergrößert, da die Grundfläche 310 gegen die Mittelachse 10 geneigt ist, so daß dadurch die Austrittsgeschwindigkeit der einzelnen Brausestrahlen entsprechend verringert wird und das Strahlbild der Brause insgesamt weicher ausfällt. Wird dagegen der Hohlkolben 14 an den Radialöffnungen 131 vorbeigeführt, so wird die Wasserzufuhr zu den Nuten 33 abgesperrt und das zufließende Wasser allein über die zentrale Düse 210 abgegeben.During the showering process, the shower water reaches the water chamber 12 via the ball head 11 in accordance with the arrows 100. Depending on the axial position of the hollow piston 14, the water flowing through the radial openings 131 into the hollow cylinder 13 either reaches the grooves 33 or the hollow piston 14, such as it is shown in the right half of Figure 1, and from here via the nozzle formation in the screw 21 as a single, bundled emerging massage jet to the outside.
At the position of the hollow piston 14 in the left half of the figure, the water flowing through the radial openings 131 into the hollow cylinder 13 passes through the axial slots 1410 into an annular space above the base part 2 and from here into the individual grooves 33 distributed over the outer jacket of the ring element 3 and is emitted here as a wreath of individual shower jets. If the hollow piston 14 is now lowered from its position shown in the left half of the figure by a screwing movement with the rotating ring 15, the base part 2 with the ring element 3 is also pushed out of the bore 16 of the rotating ring 15 to the same extent. As a result, the outlet cross section of the grooves 33 is enlarged, since the base area 310 is inclined towards the central axis 10, so that the exit velocity of the individual shower jets is correspondingly reduced and the spray pattern of the shower is generally softer. If, on the other hand, the hollow piston 14 is guided past the radial openings 131, the water supply to the grooves 33 is shut off and the inflowing water is discharged solely via the central nozzle 210.

In den einen relativ kleinen Querschnitt aufweisenden Nuten 33 und dem darüberliegenden Ringraum verbleibt in der Regel das Restbrausewasser, wenn die Brause abgestellt wird. Hierbei verdampft das im Endbereich des von der Nut 33 gebildeten Düsenkanals befindliche Wasser an der Umgebungsluft, so daß sich hier Kalk abscheiden kann, wobei gleichzeitig das verdampfte Wasser aus dem stromaufwärts gelegenen Düsenkanal und dem Ringraum aufgefüllt wird. Mit Hilfe des vorstehenden Kragens 30 kann nun der Benutzer in dem Falle, daß sich störende Kalkverkrustungen am Austrittsende aufgebaut haben, durch Abstreichen oder Walken des Kragens 30 mit der Hand diese Verkrustungen absprengen, so daß beim nächsten Duschvorgang die Nuten 33 störungsfreie Brausestrahlen abgeben können.The remaining shower water generally remains in the grooves 33, which have a relatively small cross section, and the annular space above them when the shower is turned off. Here, the water located in the end region of the nozzle channel formed by the groove 33 evaporates in the ambient air, so that lime can separate out, the evaporated water from the upstream nozzle channel and the annular space being filled up at the same time. With the help of the projecting collar 30, the user can now, in the event that disruptive scale deposits have built up at the outlet end, by wiping or flexing the collar 30 blow off these incrustations by hand so that the grooves 33 can emit 33 trouble-free shower jets during the next showering process.

Bei dem in den Figuren 2 bis 7 angegebenen Ausführungsbeispiel ist das Ringelement 3 mit vier verschieden geneigten Nuten 31,32,33,34 ausgestattet, die sich periodisch auf dem Außenmantel des Ringelements 3 wiederholen, wie es insbesondere aus Figur 3 der Zeichnung zu entnehmen ist. Die Nute 31 weist dabei eine Tiefe 3102 von 0,45 mm auf und ist mit ihrer Grundfläche 310 parallel zur Mittelachse 10 angeordnet. Die Nute 32 ist mit der Grundfläche 310 um 5° zur Mittelachse 10 geneigt ausgebildet, wie es insbesondere aus Figur 4 der Zeichnung zu entnehmen ist. Die Grundfläche 310 der Nute 33 ist mit einem Winkel von 10° gegen die Mittelachse 10 geneigt angeordnet, wie es aus Figur 5 der Zeichnung zu entnehmen ist. Die Nute 34 ist schließlich mit der Grundfläche 310 um 15° gegen die Mittelachse 10 geneigt angeordnet, wie es aus Figur 6 zu entnehmen ist. Durch die unterschiedliche Neigung der Grundfläche 310 der Nuten 31,32,33,34 kann ein gefächertes Brausebild erzeugt werden. Um ein günstiges Abstreifen oder Walken des Kragens 30 zu gewährleisten, ist hierbei die kegelförmige Verjüngung der Innenwandung 303 des Kragens 30 entsprechend gestuft ausgebildet, wie es insbesondere aus Figur 7 der Zeichnung zu entnehmen ist. Als vorteilhaft hat sich hierbei eine Neigung der Innenwandung 303 bei der Nute 31 von 15°, bei der Nute 32 von 20°, bei der Nute 33 von 25° und bei der Nute 34 von 30° erwiesen. Die Nuten 31,32,33,34 weisen dabei die gleiche Breite 3101 von 0,9 mm auf. Die kleinste Tiefe 3102 bei den Nuten 31,32,33,34 beträgt 0,45 mm.In the exemplary embodiment shown in FIGS. 2 to 7, the ring element 3 is equipped with four differently inclined grooves 31, 32, 33, 34, which are repeated periodically on the outer jacket of the ring element 3, as can be seen in particular from FIG. 3 of the drawing . The groove 31 has a depth 3102 of 0.45 mm and is arranged with its base 310 parallel to the central axis 10. The groove 32 is formed with the base 310 inclined by 5 ° to the central axis 10, as can be seen in particular from FIG. 4 of the drawing. The base surface 310 of the groove 33 is arranged inclined at an angle of 10 ° to the central axis 10, as can be seen in FIG. 5 of the drawing. The groove 34 is finally arranged with the base area 310 inclined by 15 ° relative to the central axis 10, as can be seen from FIG. 6. Due to the different inclination of the base area 310 of the grooves 31, 32, 33, 34, a fanned shower image can be generated. In order to ensure that the collar 30 is stripped or flexed favorably, the conical tapering of the inner wall 303 of the collar 30 is designed in a correspondingly stepped manner, as can be seen in particular from FIG. 7 of the drawing. An inclination of the inner wall 303 for the groove 31 of 15 °, for the groove 32 of 20 °, for the groove 33 of 25 ° and for the groove 34 of 30 ° has proven to be advantageous. The grooves 31, 32, 33, 34 have the same width 3101 of 0.9 mm. The smallest depth 3102 for the grooves 31, 32, 33, 34 is 0.45 mm.

Das in den Figuren 8 bis 13 dargestellte Ausführungsbeispiel unterscheidet sich zu dem in den Figuren 2 bis 7 dargestellten Ausführungsbeispiel lediglich dadurch, daß der vorstehende Kragen 30 von einzelnen um die Nuten 31,32,33,34 ausgebildeten Vorsprüngen 302 gebildet wird, wie es insbesondere aus Figur 8 und 13 zu entnehmen ist. Mit den einzelnen Vorsprüngen 302 läßt sich besonders günstig ein Abstreifen und Walken zur Entfernung von Kalkverkrustungen erreichen.The exemplary embodiment shown in FIGS. 8 to 13 differs from the exemplary embodiment shown in FIGS. 2 to 7 only in that the projecting collar 30 is formed by individual projections 302 formed around the grooves 31, 32, 33, 34, as is particularly the case can be seen from Figures 8 and 13. With the individual protrusions 302, stripping and milling can be achieved particularly cheaply in order to remove scale deposits.

Bei den drei Ausführungsbeispielen ist der Bodenteil 2 aus Kunststoff im Spritzgußverfahren hergestellt. Vorteilhaft kann hierbei der Kunststoff Polypropylen eingesetzt werden. Das Ringelement 3 ist dabei aus einem thermoplastischen Elastomer (TPE) an dem Bodenteil 2 als Verbundwerkstoff angespritzt worden. Hierbei hat sich das thermoplastische Elastomer "Santoprene" als günstig erwiesen.
Selbstverständlich kann aber auch das Ringelement 3 aus einem anderen geeigneten gummielastischen Werkstoff hergestellt sein und an der Mantelfläche des aus einem geeigneten Werkstoff hergestellten Bodenteils 2 anvulkanisiert oder angeklebt werden. Auch kann der Bodenteil 2 mit einer umlaufenden Ringnut versehen werden, in die ein am Ringelement 3 umlaufender, innerer Ringbund in der Stecklage einschnappt, so daß das Ringelement 3 in axialer Richtung formschlüssig vom Bodenteil 2 gehalten wird.In the three exemplary embodiments, the base part 2 is made of plastic by injection molding. The plastic polypropylene can advantageously be used here. The ring element 3 has been injection molded from a thermoplastic elastomer (TPE) on the base part 2 as a composite material. The thermoplastic elastomer "Santoprene" has proven to be cheap.
Of course, however, the ring element 3 can also be made of another suitable rubber-elastic material and vulcanized or glued to the outer surface of the base part 2 made of a suitable material. The bottom part 2 can also be provided with an encircling annular groove into which an inner annular collar encircling the ring element 3 snaps in the plug-in position, so that the ring element 3 is held positively in the axial direction by the bottom part 2.

Bei den in der Zeichnung angegebenen Ausführungsbeispielen ist der Bodenteil 2 mit dem Ringelement 3 axial zum Gehäuse 1 des Brausekopfes beweglich angeordnet. Selbstverständlich kann der Bodenteil 2 mit dem Ringelement 3 auch ortsfest im Brausekopf angeordnet werden. Hierbei können auch z.B. konzentrisch mit verschiedenen Durchmessern angeordnete Ringelemente vorgesehen sein, so daß auch mehrere Reihen von Brausestrahlen erzeugbar sind. Ferner kann auch die Bohrung 16 mit ihrer Wandung gummielastisch im Bereich der Anlage des Ringelements 3 ausgebildet oder ausgekleidet sein.In the exemplary embodiments shown in the drawing, the base part 2 with the ring element 3 is arranged to be movable axially with respect to the housing 1 of the shower head. Of course, the bottom part 2 with the ring element 3 can also be arranged in a fixed position in the shower head. Here, e.g. Ring elements arranged concentrically with different diameters can be provided, so that several rows of shower jets can also be generated. Furthermore, the bore 16 can be rubber-elastic or lined with its wall in the region of the contact of the ring element 3.

Schließlich können auch der Bodenteil mit dem Ringelement einstückig aus einem gummielastischen Werkstoff hergestellt werden. Hierbei kann der Tragbereich des Bodenteils entsprechend dickwandig ausgebildet werden und/oder einen Tragkörper, z. B. Metallplatte, aufweisen, so daß eine erforderliche Formstabilität gewährleistet ist.Finally, the base part with the ring element can also be produced in one piece from a rubber-elastic material. Here, the support area of the base part can be made correspondingly thick-walled and / or a support body, for. B. metal plate, so that a required dimensional stability is ensured.
