Die beiden zweiten Enden der beidseits der Ablage angeordneten Schwenkarme sind dabei über eine Synchronisationsstange miteinander gekoppelt, die in ihrer Länge variabel einstellbar ist. A lifting mechanism according to the invention comprises a pair of sliding pivoting mechanisms having at least two swivel arms rotatably mounted on one of the side walls of the body with a first end parallel to the plane of the side walls and spaced parallel to each other, at respective second ends of the pivot arms a guide rail parallel to Level of the side walls are pivotally fixed, that the guide rail is pivotable from a lower position within the body in a raised, upper position at least partially outside of the body, at least one linearly displaceable in the guide rail running rail to which the tray is attached. The two second ends of the arranged on both sides of the tray pivot arms are coupled together via a synchronization rod, which is variably adjustable in length.
Ein alternativ erfindungsgemäßer Hebemechanismus weist eine Scherenme- chanik mit zwei Paaren von gekreuzten und drehbar miteinander verbundenen Scherenhebeln zum Anheben und Absenken der Ablage auf.
