Abstract:
A toy gearing system comprising:a drive unit, said drive unit comprising an elongated body having symmetrical lateral sides and having a curvilinear nose shaped portion at one axial extremity, said curvilinear nose shaped portion having symmetrical generally arcuate side slots through which at least some of the teeth of the respective gearwheel protrude, said side slots collectively defining a single slot that is generally arcuate and extends around the curvilinear nose shaped portion over an angle of at least 180Â° and a first gearwheel supported by the body, said gearwheel comprising gear teeth wherein teeth disposed on at least 180Â° of the angular extent of said first gearwheel extend radially beyond said curvilinear nose shaped portion and are exposed for gear engagement, the drive unit further including an electric motor for rotating the first gearwheel and a drive transmission means provided between the motor and the first gearwheel; and a gear unit comprising a second body and a second gearwheel supported by the second body for rotation by the first gearwheel of the drive unit, said second body being in the form of a base supporting the second gearwheel above it for rotation, the base being circular and smaller than the respective gearwheel, and the gearwheel is supported co-axially on the base such that all of its teeth protrude beyond the perimeter of the base, each of said bodies including respective self-attaching means for attaching the drive and gear units onto a flat surface at selected positions with the first and second gearwheels in meshing engagement for simultaneous rotation.
