  • Patent number: 5487438
    Abstract: A driving system for an electric vehicle which drives wheels thereof with the aid of an AC motor via an inverter while a battery is used as a power source is constructed such that the primary side and the secondary side of the AC motor are rotatably supported in a motor frame. One of the primary and the secondary sides of the AC motor is operatively connected to a power transmission shaft for one of a left-hand wheel and a right-hand wheel via a reversible type speed reducing mechanism while the direction of rotation of the power transmission shaft is reversed relative to that of the one of the primary and secondary sides. The other one of the primary and the secondary sides of the AC motor is operatively connected to a power transmission shaft for the other one of the wheels via a non-reversible type speed reducing mechanism while the direction of rotation of the power transmission shaft is kept unchanged relative to that of the other one of the primary and secondary sides.

  • Patent number: 5445399
    Abstract: A positive locking arrangement for a retractable leg of a collapsible hand truck. A slide connected to the hand truck front axle is retained within a slot formed in a tab connected to the retractable leg. The slide includes a projection interlocking the tab thereto. To disengage the locked members, the retractable leg must be swung backwardly in a first motion, thus aligning the slot with the projection. In a second motion, the slide is then raised, the projection just passing through the slot, and the slide continues to feed through the tab, coming to a final vertical position parallel to and against the hand truck body. The slide terminates at an angle, thus cooperating with the tab so as to be urged by gravity to a lowermost position, thus favoring engagement. The tab is inclined to extend upwardly from its anchoring point, thus limiting downward movement of the slide. A removable pin or hook is inserted into the slot when it is desired to secure the slide in the deployed, locked condition.
