  • Patent number: 11214326
    Abstract: A portable conveyance footrest has a support portion having a substantially planar base surface to receive a foot. A tow handle portion is connected to an end of the support portion and forms a substantially planar tow handle that is within a same plane as the substantially planar base surface. The tow handle is spaced apart from the end of the support portion to define a void between the tow handle and the second end of the support portion. The tow handle is disposed within the same plane as the substantially planar base surface so that a user's fingers, when gripping the tow handle, extend into the void between the tow handle and the end of the support portion and through the plane of the substantially planar surface.

  • Patent number: 9586643
    Abstract: A portable conveyance has a deck, a front drive wheel proximately disposed to a first end of the deck and a rear drive wheel attached proximate to a second end of the deck. A guide roller assembly attached proximate to the rear drive wheel. The guide roller assembly has a first rotational axis and the rear drive wheel rotates about a second rotational axis different from the first rotational axis and parallel to the first rotational axis, such that the guide roller assembly is not in contact with a substantially flat surface when the first and rear drive wheels are in contact with the substantially flat surface, and the guide roller assembly is in rotational contact with the surface when the deck is lifted into a towing position.
