Ein Trockenrasierapparat der eingangs genannten Art ist aus der EP-A-0267 044 bekannt. Der zwischen dem Antriebshebel und den beiden Untermessern außerhalb des Gehäuses angeordnete Gelenkrahmen besteht aus einem am Antriebshebel quer zur Längsachse der Untermesser schwenkbar angelenkten Lagerblock mit einer parallel zur Längsachse der Untermesser verlaufenden Lagerbohrung, einem in dieser Lagerbohrung schwenkbar gelagerten, starren Rahmen, an dessen äußeren Stirnseiten jeweils zwei Lagerbolzen angeordnet sind und zwei parallel zueinander angeordnete, U-förmig ausgebildete Träger, deren Trägerschenkel endseitig mittels Lagerbohrungen auf den Lagerbolzen des starren Rahmens schwenkbar gelagert. sind. Auf der Oberseite eines jeden U-förmig ausgebildeten Trägers ist ein Untermesser unter Zwischenschaltung einer Blattfeder befestigt.A dry shaver of the type mentioned is known from EP-A-0267 044. The articulated frame arranged between the drive lever and the two lower knives outside the housing consists of a bearing block pivotally articulated on the drive lever transversely to the longitudinal axis of the lower knives with a bearing bore running parallel to the longitudinal axis of the lower knives, a rigid frame pivotably mounted in this bearing bore, on the outer end faces thereof In each case two bearing bolts are arranged and two parallel, U-shaped supports, the support legs of which are pivotally mounted on the end of the rigid frame by means of bearing bores. are. On the top of each U-shaped carrier, a lower knife is attached with the interposition of a leaf spring.

Aufgabe der Erfindung ist es, für einen Rasierapparat der eingangs genannten Art eine Steuerung für die beiden in Längsrichtung verlaufenden Untermesser zu schaffen, mittels der die Führung der Untermesser in vertikaler Richtung verbessert wird.The object of the invention is to provide a control for the two longitudinally extending lower knives for a shaving apparatus of the type mentioned above, by means of which the guidance of the lower knives in the vertical direction is improved.

Nach der Erfindung wird diese Aufgabe bei einem Gerät der eingangs genannten Art dadurch gelöst, daß zwischen den Trägerelementen ein Verbindungselement angeordnet ist und eine Gelenkverbindung zwischen dem Verbindungselement und dem jeweiligen Trägerelement besteht.According to the invention, this object is achieved in a device of the type mentioned in the introduction in that a connecting element is arranged between the carrier elements and there is an articulated connection between the connecting element and the respective carrier element.

Die Ausbildung und Lagerung des zweiten Gelenkrahmens auf dem aus dem Gehäuse des Trockenrasierapparates herausragenden Antriebselement gewährleistet eine exakte parallele Koppelung und Ausrichtung der beiden Untermesser auf den ihnen zugeordneten Trägerelementen des zweiten Gelenkrahmens sowie eine exakte parallele Bewegung der beiden Untermesser relativ zueinander in vertikaler Richtung und darüber hinaus eine lineare Schwingbewegung in horizontaler Richtung. Die beiden Untermesser werden sonach über die vertikal bewegbaren Trägerelemente des zweiten Gelenkrahmens unter Aufrechterhaltung der parallelen Anordnung linear angetrieben. Die Koppelung der Untermesser durch den zweiten Gelenkrahmen erleichtert das Abnehmen und das Aufsetzen des mit in vertikaler Richtung relativ zueinander bewegbaren Obermessern ausgestatteten Scherkopfrahmens vom bzw. auf das Gehäuse des Rasierapparates.The formation and mounting of the second articulated frame on the drive element protruding from the housing of the dry shaving apparatus ensures an exact parallel coupling and alignment of the two lower knives on the support elements of the second articulated frame assigned to them, as well as an exact parallel movement of the two lower knives relative to one another in the vertical direction and beyond a linear swinging motion in the horizontal direction. The two lower knives are then linearly driven via the vertically movable support elements of the second articulated frame while maintaining the parallel arrangement. The coupling of the lower knives by the second articulated frame makes it easier to remove and put on the shaving head frame equipped with upper knives that are movable in the vertical direction relative to one another from or onto the housing of the shaving apparatus.

Nach einer Ausführungsform der Erfindung sind die Drehgelenke aus in den jeweiligen Stirnwänden der Trägerelemente angeordneten Lagerbohrungen und durch an dem Rahmen angeordneten, in diese Lagerbohrungen eingreifende Lagerbolzen gebildet. Vorzugsweise ist die Gelenkverbindung zwischen Verbindungselement und dem jeweiligen Trägerelement durch Filmscharniere gebildet.According to one embodiment of the invention, the rotary joints are formed from bearing bores arranged in the respective end walls of the carrier elements and from bearing bolts arranged on the frame and engaging in these bearing bores. The articulated connection between the connecting element and the respective carrier element is preferably formed by film hinges.

Nach der Erfindung sind die Drehgelenke sowie die Gelenkverbindung des Trägerelements mit dem Verbindungselement auf einer gemeinsamen vertikalen Achse y-y und die Drehgelenke sowie die Gelenkverbindung des Trägerelements mit dem Verbindungselement auf einer gemeinsamen, parallel zur Achse y-y verlaufenden, vertikalen Achse z-z angeordnet.According to the invention, the rotary joints and the articulated connection of the carrier element with the connecting element are on a common one vertical axis yy and the rotary joints as well as the articulated connection of the carrier element with the connecting element are arranged on a common vertical axis zz running parallel to the axis yy.

Zweckmäßigerweise ist der Antriebshebel mit dem Rahmen mittels zweier Drehgelenkverbindungen gekoppelt. Vorzugsweise sind die Drehgelenkverbindungen aus in den Stirnseiten des Antriebshebels gelagerten Kugeln und in in den Innenseiten der Stirnwände des Rahmens eingeformten Lagerschalen gebildet. Um eine einfache und leichte Koppelung bzw. Entkoppelung des zweiten Gelenkrahmens mit bzw. vom Antriebshebel zu ermöglichen, ist wenigstens eine der Kugeln von einer in dem Antriebshebel angeordneten Feder beaufschlagt.The drive lever is expediently coupled to the frame by means of two swivel connections. The swivel connections are preferably formed from balls mounted in the end faces of the drive lever and into bearing shells molded into the inner sides of the end walls of the frame. In order to enable simple and easy coupling or uncoupling of the second joint frame with or from the drive lever, at least one of the balls is acted upon by a spring arranged in the drive lever.

Nach der Erfindung sind die Lagerbolzen paarweise gegenüberliegend über die jeweiligen Außenseiten der Stirnwände des Rahmens hinausragend an dem Rahmen angeordnet. Nach einer zweckmäßigen Ausführungsform wird durch die Anordnung und den Abstand der jeweiligen Lagerschale zu den jeweiligen, paarweise angeordneten Lagerbolzen jeweils ein gleichschenkliges Dreieck gebildet.According to the invention, the bearing bolts are arranged in pairs on the frame opposite the respective outer sides of the end walls of the frame. According to an expedient embodiment, an isosceles triangle is formed by the arrangement and the distance of the respective bearing shell from the respective bearing bolts arranged in pairs.

Nach einer Ausführungsform der Erfindung ist das Verbindungselement an den den Untermessern zugewändten Enden der Trägerelemente angeordnet und von den Stirnwänden der Trägerelemente durch einen Spalt getrennt.According to one embodiment of the invention, the connecting element is arranged on the ends of the carrier elements facing the lower knives and is separated from the end walls of the carrier elements by a gap.

Um eine ungehinderte Bewegung der relativ und parallel zueinander bewegbaren Trägerelemente und der an diesen angeformten Kupplungsarme zu erzielen, ist in den in Längsrichtung verlaufenden Seitenwänden des Verbindungselements jeweils eine rechteckförmige Aussparung eingeformt.In order to achieve unimpeded movement of the support elements movable relative to and parallel to one another and of the coupling arms formed thereon, a rectangular recess is formed in each of the longitudinal side walls of the connecting element.

Vorzugsweise ist an jedem Trägerelement ein sich in vertikaler Richtung erstreckender Kupplungsarm auf der jeweiligen Achse y-y und z-z liegend angeformt.A coupling arm, which extends in the vertical direction, is preferably integrally formed lying on the respective axis y-y and z-z.
