A rebar hole doweling cart to construct or repair sidewalks, driveways, roadways, curbs, floors and the like. The cart has a frame with wheels, an elongated upwardly extending riser with a handle, and a nose plate that pivotally supports a drill mounting assembly near the ground. The mounting assembly holds an electric hammer drill and its bit in an aimed direction. The cart is rolled forward to tap a hole in a concrete slab and place the bit in a set aimed direction. The cart handle is then pushed forward to rotate the nose plate down into gripping engagement with the ground to advance the drill bit forward to form the rebar hole in the slab. During this forward handle rotation, the drill mounting assembly simultaneously counter-rotates (pitch pivotal movement) relative to the nose plate to maintain the drill bit in its set aimed direction.

The present invention is a rebar hole doweling cart that pivotally holds an electric hammer drill near the ground to tap a hole and place the bit in a set aimed direction, and grips engages the ground to produce a manually-generated leveraged pushing force to drill rebar or dowel holes into a slab of concrete to construct or repair sidewalks, driveways, roadways, curbs, floors and the like. The cart has a frame, wheels, an elongated handle, a nose plate and a drill mounting assembly. The wheels position the cart and drill in front of the concrete slab. The elongated, upwardly extending handle is manually pushed or stroked forward to rotate the nose plate into gripping engagement with the ground and advance the drill bit forward. The drill mounting assembly simultaneously counter-rotates during the stroke to maintain the drill bit in its set aimed direction as the bit advances into the slab to form the hole.

The present application pertains to a rebar hole doweling cart to construct or repair sidewalks, driveways, roadways, curbs, floors and the like. The cart has a frame with wheels, an elongated upwardly extending riser with a handle, and a nose piece that pivotally supports a drill mounting assembly near the ground. The mounting assembly holds an electric hammer drill and its bit in an aimed direction. The cart is rolled forward to tap a hole in a concrete slab and place the bit in a set aimed direction. The cart handle is then pushed forward with the nose piece in gripping engagement with the ground to advance the drill bit forward to form the rebar hole in the slab. During this forward handle rotation, the drill mounting assembly simultaneously counter-rotates (pitch pivotal movement) relative to the nose piece to substantially maintain the drill bit in its set aimed direction.
