Die Lagerzapfen greifen in zugeordnete Lagerbohrungen der Gleitsohle ein. Die Gleitsohle ist an den Lagerschalen vertikal abgestützt. Auf die Gleitsohle wirkende Kräfte werden über die Lagerschalen in das Kunststoffgehäuse eingeleitet. Die Lagerzapfen sind kaum beansprucht und können entsprechend klein dimensioniert werden. An den Innenflächen des Kunststoffgehäuses sind zweckmäßig Anschläge angeformt, die den Schwenkwinkel der Gleitsohle begrenzen. Die Anschläge können aus Zapfen bestehen, die in ein am Umfang der Gleitsohle angeordnetes Langloch eingreifen.According to a preferred embodiment of the invention the inner surfaces of the plastic housing journal and as Bearing cups formed projections. The bearing journals engage in associated bearing holes in the sliding sole on. The sliding sole is vertical on the bearing cups supported. Forces acting on the sliding sole are over the bearing shells introduced into the plastic housing. The Bearing journals are hardly stressed and can be used accordingly be dimensioned small. On the inner surfaces of the Plastic housing are suitably molded stops that limit the swivel angle of the sliding sole. The attacks can consist of cones, which in a on the circumference of Engage the slot arranged in the sliding sole.
Die Schraubdome sind gemäß einer vorteilhaften Ausgestaltung der Erfindung mit seitlichem Versatz zur Schwenkachse angeordnet. Die auf die Borstenträgerplatte wirkenden Druckfedern sind an Ringscheiben abgestützt, die auf den Schraubdomen befestigt sind. Die Gleitsohle ist schwenkbeweglich mit dem Kunststoffgehäuse verbunden und gegenüber den Schraubdomen beweglich. Soll der Saugkopf mit einer starr an dem Kunststoffgehäuse befestigten Gleitsohle ausgerüstet werden, so ist dies auf sehr einfache Weise dadurch möglich, dass die Gleitsohle bei unveränderter Ausbildung des Kunststoffgehäuses an die Schraubdome angeschraubt wird. Die Druckfedern sind bei einer Ausführung mit starr befestigter Gleitsohle zwischen der Gleitsohle und der Borstenträgerplatte eingespannt.The screw domes are according to an advantageous Embodiment of the invention with lateral offset Swivel axis arranged. The on the bristle carrier plate acting compression springs are supported on washers, the are attached to the screw domes. The sliding sole is pivotally connected to the plastic housing and movable towards the screw domes. If the suction head with a sliding sole rigidly attached to the plastic housing be equipped, this is very simple possible that the sliding sole with unchanged Formation of the plastic housing on the screw domes is screwed on. The compression springs are at one Version with rigidly attached sliding sole between the Slide sole and the bristle carrier plate clamped.
Erfindungsgemäß ist das Kunststoffgehäuse des Saugkopfes ein Standardbauteil, welches unverändert bei Ausführungen des Saugkopfes mit beweglicher und mit starrer Gleitsohle eingesetzt werden kann. Sofern der Saugkopf mit einer starr befestigten Gleitsohle ausgerüstet werden soll, sind lediglich an der Gleitsohle geringfügige Modifikationen vorzunehmen. Sie bestehen darin, die Gleitsohle mit zusätzlichen, den Schraubdomen zugeordneten Bohrungen auszubilden, durch die Schrauben in die Schraubdome eingedreht werden können. Die Montage des erfindungsgemäßen Saugkopfes ist denkbar einfach, da das Kunststoffgehäuse und die Gleitsohle durch eine Rastverbindung miteinander verbunden werden.According to the invention, the plastic housing of the suction head a standard component, which remains unchanged in versions of the suction head with movable and with rigid sliding sole can be used. Unless the suction head is rigid attached sliding soleplate are to be equipped only minor modifications to the sliding sole make. They consist of having the sliding sole additional holes assigned to the screw domes train through the screws into the screw domes can be turned. The assembly of the invention Suction head is very simple because of the plastic housing and the sliding sole by a snap connection get connected.
