Concrete renovator tool

Abstract

This invention is a concrete renovator tool with a dust guard, swivel bracket and vacuum handle of special design, for attachment to a small (100 mm-125 mm) angle grinder. By the use of the various pieces and interconnecting designs, the concrete renovator tool allows operators to grind ceilings, in particular, while standing on the floor. It provides for a more efficient and faster method of concrete grinding, and can be used by painters, form workers and drywall contractors to preform a variety of different grinding, sanding and plastering tasks. It allows for a dust-free environment and also results in less workplace injuries.

1 . A concrete renovator tool that is primarily used in grinding ceilings, which comprises: 
 a dustless guard with a 45° angle junction of push-on configuration for attachment to a hose, with the dustless guard being attached to the bottom ring section of the grinder by a metal clamp;    a wire brush strip around the outer circumference of the dustless guard to facilitate movement over uneven concrete surfaces and provide effective dust extraction;    a bracket with a kidney shaped head which houses the grinder, with the inferior end of the grinder being held in place by a toggle hook attached to the inferior ventral (lower front) section of the bracket, and the superior medial lateral section of the grinding head being secured by two metal ties that extend from the superior lateral ventral section of the bracket;    a swivel bracket section attaches to the bracket in a posterior position by an axel to provide a pivoting action for the bracket and grinder when grinding uneven surfaces, with the swivel bracket having wheels as well as adjustable sliding leg sections held in place by bolts to provide working alignment;    an attachment pole that consists of a long, hollow cylindrical tube, with two exhaust junctions to provide for dust extraction, the first junction inlet being located on the lateral superior section of the attachment pole, and the second junction for vacuum hose attachment located at the inferior section of the pole;    a moveable head of plastering flatbox type for tool placement and working alignment on work surfaces is attached at the superior end of the attachment pole, and is operated by a brake and cable from the inferior end of the attachment pole, with the brake being attached to a cylindrical collar which also serves as a hand grip;    a safety chain is fixed to the moveable head of the attachment pole and is then attached to a ring on the superior lateral dorsal section of the bracket, the safety chain ensuring that the bracket and grinder will not become dislodged from the handle; and    a short hose that is attached at one end to the 45° angle junction of the dustless guard, and at the other end to the junction inlet located on the lateral superior section of the attachment pole.    
   
   
       2 . A concrete renovator tool substantially as herein described with reference to the accompanying drawings.
