  • Combination stepladder/handtruck apparatus
    Patent number: 5836595
    Abstract: A stepladder/handtruck combination is used as a stepladder in a first position and as a handtruck in a second configuration. A plurality of steps are positioned to move between horizontal positions in the stepladder configuration and positions substantially parallel to the frame when the combination is being used in the handtruck configuration. A pair of wheels provides for convenient transport and a support plate used in the handtruck configuration is pivotal about a frame member and assumes a position parallel thereto when the combination is stored. Links connect the steps to the frame and provide for displacement of the steps when the combination is moved between the stepladder and handtruck configurations.
