Stand-up grinder caddy with adjustable height and low profile floating head

A stand-up grinder caddy apparatus for a detachable grinder for a floor surface, the apparatus comprising:

• means for moving the apparatus, with a front handle, a back handle and an upper sheath;
• means for rolling the apparatus, with a wheel assembly, a support frame and a lower sheath inserted into said upper sheath;
• means for supporting the grinder below said support frame;
• means for allowing the grinder to move relative to said support frame to follow contours of the floor surface;
• and
• means for adjusting a height of said moving means relative to said support frame by adjusting an amount of insertion of said lower sheath into said upper sheath.

A stand-up grinder caddy apparatus for a detachable grinder for a floor surface, the apparatus comprising:

• an upper caddy comprising a handle assembly comprising a front handle and a back handle and an upper sheath positioned vertically downward and proximate said back handle;
• a lower caddy comprising a wheel assembly, a lower sheath positioned vertically upward and proximate said wheel assembly, said lower sheath comprising a diameter suitable for insertion into said upper sheath, a support frame extending horizontally from said wheel assembly, a bracket for supporting a front portion of the grinder, said bracket attached to a distal end of said support frame with a rod end joint and to sides of said support frame with a floating head mechanism comprising a plurality of floating head levers and springs arranged so as not to extend above a top of said support frame and thus minimize a height of said lower caddy for fitting under low overhanging obstacles such that a grinder head of the grinder contacts the floor surface and can follow contours of the floor surface, left and right alignment posts attached to said support bracket for positioning a handle of the grinder between said alignment posts, a tilt lever attached to said support frame comprising a first end disposed in said lower sheath and a second end disposed in a opening of said support frame and a handle harness attached to said second end for vertically supporting the handle of the grinder;
• a tilt activating mechanism comprising a tilt handle attached to a tilt rod, said tilt handle positioned proximate said handle assembly with said tilt rod extending through said upper and lower sheaths contacting said tilt lever where when said tilt handle is pressed said handle harness is vertically raised and the grinder head can be tilted;
• and
• a height adjustment mechanism attached to said upper sheath where when said height adjustment mechanism is disengaged a vertical position of said upper sheath relative to said lower sheath can be adjusted for different user heights and when said height adjustment mechanism is engaged said vertical position is maintained and said first handle is positioned in a first position on a vertical line passing through the grinder head such that said user can supply a downward pressure on said front handle to speed a grinding process of the floor surface and when said height adjustment mechanism is disengaged said upper caddy can be rotated to a second position such that said lower caddy can pass under overhanging obstacles.
