Abstract

Die Offenbarung betrifft eine Verbindungsvorrichtung zum lösbaren Ankuppeln eines Anbaugerätes an eine Arbeitsvorrichtung, umfassend: eine an der Arbeitsvorrichtung festgelegte oder festlegbare Trageinrichtung, an der eine erste Aufnahme für ein erstes Kupplungsteil des Anbaugerätes und eine zweite Aufnahme für ein zweites Kupplungsteil des Anbaugerätes gebildet sind, wobei die Aufnahmen im Abstand zueinander an der Trageinrichtung angeordnet sind; eine an der Trageinrichtung gehaltene Verriegelungseinrichtung, die einen Aktuator und ein von diesem von einer Lösestellung in eine Haltestellung und umgekehrt überführbares Verriegelungselement umfasst, wobei die erste Aufnahme in der Lösestellung zum Einführen des ersten Kupplungsteils freigegeben ist und das erste Kupplungsteil in der Haltestellung in der ersten Aufnahme gehalten ist; eine Sicherungseinrichtung, die ein insbesondere an der Trageinrichtung beweglich gehaltenes Sicherungselement umfasst, das von einer Freigabestellung in eine Sicherungsstellung und umgekehrt überführbar ist, wobei eine Einführöffnung der zweiten Aufnahme für das zweite Kupplungsteil in der Freigabestellung freigegeben und in der Sicherungsstellung gesperrt ist; und eine Kopplungseinrichtung, über die die Sicherungseinrichtung mit der Verriegelungseinrichtung in Wirkverbindung steht, wobei das Sicherungselement beim Überführen des Verriegelungselementes von der Haltestellung in die Lösestellung von der Sicherungsstellung in die Freigabestellung überführt wird. Außerdem betrifft die Offenbarung eine Arbeitsvorrichtung mit einer Verbindungsvorrichtung.The disclosure relates to a connecting device for releasably coupling an attachment to a working device, comprising: a support device which is or can be fixed to the working device and on which a first receptacle for a first coupling part of the attachment and a second receptacle for a second coupling part of the attachment are formed, wherein the receptacles are arranged at a distance from one another on the support device; a locking device held on the support device, which comprises an actuator and a locking element that can be transferred by this from a release position to a holding position and vice versa, wherein the first receptacle is released in the release position for inserting the first coupling part and the first coupling part in the holding position in the first recording is held; a securing device which comprises a securing element which is held movably in particular on the carrying device and which can be transferred from a release position to a securing position and vice versa, with an insertion opening of the second receptacle for the second coupling part being released in the release position and blocked in the securing position; and a coupling device via which the securing device is in operative connection with the locking device, the securing element being transferred from the securing position to the release position when the locking element is transferred from the holding position to the release position. In addition, the disclosure relates to a working device with a connection device.
