Concrete Slab Rebar Hole Dowling Cart

A rebar hole doweling cart that holds a drill for drilling rebar or dowel holes into a concrete slab with a slab side and generally planarly aligned upper and lower slab surfaces, an area of ground in front of the slab side, the slab side having a slab side middle region spaced from the slab surfaces, the drill having a front drill end and a drill bit extending from the front drill end in a drill aimed direction, the rebar hole doweling cart comprising:

• a cart frame adapted to engage the ground, said frame having an elongated upwardly extending cart riser with a cart handle, said cart handle being adapted to be gripped by a worker;
• a nose piece rigidly secured to said cart frame, said nose piece having a nose plate with a front nose end, said front nose end being forward of said cart frame, said nose plate, cart riser and can handle selectively rotating in fixed unison, said front nose end forming a nose pivot point, and said nose plate front end is adapted to selectively engage and grip the ground about said nose pivot point when said cart handle is pushed forward and selectively release from gripping engagement with the ground when said cart handle is pulled back;
• a drill mounting assembly pivotally secured to either one of said nose piece and said frame to allow assembly pitch pivotal movement relative to said nose plate, said mounting assembly having an assembly aimed direction perpendicular to said front nose end, said mounting assembly firmly holding the drill with the drill aimed direction in parallel alignment with said assembly aimed direction, and said mounting assembly positioning the drill bit laterally perpendicular to said front nose end and forward said nose plate pivot point, said mounting assembly having a substantially set aimed direction when the drill bit is in tapped engagement with the slab side middle region, said assembly pitch pivotal movement being in simultaneous counter-rotation to said forward rotation of said nose plate to maintain said mounting assembly and drill aimed directions in said set aimed direction when said handle and nose plate are rotated in fixed unison about said nose pivot point;
• wherein said cart is adapted to move to the area in front of the slab side with said drill bit in tapped engagement with the slab side middle region, said assembly and drill aimed directions being in laterally perpendicular alignment with the slab side middle region and substantially parallel alignment with the slab surfaces;
• and,
• wherein said cart handle is adapted to be pushed forward to rotate said cart frame and nose plate about said nose pivot point to forwardly advance said drill mounting assembly and the drill bit to form the rebar or dowel hole into the side slab middle region, said assembly and drill aimed directions being substantially maintained in said set aimed direction and in substantially planar alignment with the slab surfaces during said assembly pitch pivotal movement.
