  • Patent number: 7597610
    Abstract: An apparatus for a stand-up grinder caddy includes a handle assembly and an upper sheath. A lower caddy includes a wheel assembly and a lower sheath for insertion into the upper sheath. A bracket supports a grinder with the bracket attached to a support frame with a joint and to sides of the support frame with a floating head mechanism arranged so as not to extend above a top of the frame and thus minimize a height of the lower caddy for fitting under low overhanging obstacles. A head of the grinder contacts the floor surface and can follow contours of the floor surface. When a tilt handle is pressed the head can be tilted. A height adjustment mechanism adjusts a vertical position of the handle assembly for different user heights. The handle assembly can be rotated to a position such that the lower caddy can pass under overhanging obstacles.
