ABSTRACT:
A rope drum gear for a child's toy, for example a toy crane, is constructed such that a child can operate an elevating mechanism and a grab spade by way of ropes via the drum gear. A crank handle for actuating the mechanisms is connected to a split rotating drum by way of crank case wheel. The hub of the crank case is constructed as a sun wheel of a planetary wheel gear, which planetary wheel gear is in turn connected with a first half of the split rope drum. The first half of the split rope drum is connected via a rope to the grab spade operating mechanism. The first half of the drum when rotated engages the second hair by way of a clutch mechanism, the second half of the drum connected by a rope to the elevating mechanism of the crane. In this way, a child can reproduce the operation of a full-scale crane in a manner easy to operate and understand for the child.
