Patent ID: 11118836

Abstract:
A reusable drywall air injector is fashioned from durable, rigid material. A pointed tip for piercing drywall extends from a hollow cylinder around which is disposed a helical blade. A hollow hex section is connected between the hollow cylinder and a hollow nipple, the interiors of the cylinder, the hex section and the nipple interconnecting to form a path for compressed air. Embodiments of the injector further fashion the interior of the hollow cylinder with notches adapted to receive a driver head. The injector is inserted into drywall by driving the injector by means of a motorized drill or screwdriver engaging the injector either by deep well socket around the hex section or, in embodiments, by appropriate driver head engaging the cooperating notches in the hollow cylinder. After use, the injector may be removed from drywall for reuse by the same means operated in reverse.
