  • Patent number: 6142490
    Abstract: Improved support and adjustment of the frame on the boot are obtained by providing mounting brackets that extend transversely outwardly and beyond the underlying side walls between which the roller wheels are mounted and that contain transverse mounting slots whose transverse extents are at least as great as the spacing distance between the underlying side walls. Improved parallelism of the axles is obtained by providing diametrically opposed lobes in a mounting hole in one of the side walls at each wheel mount and by providing the corresponding axle head with a complementary shape fitting to that portion of the mounting hole containing the lobes. A tool for installing and removing the wheels from the frame is also disclosed.
