Patent ID: 7913349

Claim:
A hand held tool intended for scraping adhered material from a surface, said tool comprising; (a)two similarly shaped planar elements, each said element formed with at least 2 opposing parallel edges wherein one edge of both said elements are conjoined to form a shared pivot axis and said opposing parallel edges of said elements are configured as scraping edges, (b)a handle attached to said pivot axis wherein the longitudinal axis of said handle is oriented in a perpendicular orientation to said pivot axis and mounted to said pivot axis such that said handle is permitted to pivot freely about said pivot axis to allow said two scraping edges to remain in contact with said surface independently from said handle orientation, (c)and wherein said pivot axis contains a first set of mechanical features providing a means to limit relative rotation between said planar elements such that the configuration defined by the scraping edges of both said elements having contact with said surface and said elements splayed to the maximum angular position allowed by said mechanical features will be conducive to removing material from said surface as a force is applied in a generally simultaneous downward and fore and aft manner along the axis of said handle, (d)and wherein said pivot axis contains a second set of mechanical features providing a means to deter the free motion between said planar elements such that said planar elements will remain in their maximum and minimum relative angular positions with no external force applied, (e) and wherein said pivot axis contains a third set of mechanical features providing a means to restrain said planar elements relative to said handle as said planar elements are rotably positioned in contact with said handle.
