Abstract:
1. A concrete trowel to form a shape into at least one edge of a poured concrete structure with the poured concrete structure having an upper surface and at least one outward edge abutting a frame having a transverse side facing the at least one outward edge of the poured concrete structure, the concrete trowel comprising: a. a transverse lip having a top edge and a transverse outer surface which engages the traverse side of the abutting frame as a guide; b. a multi-rounded shape design shaped portion having first, second and third arcuate surface sections, the first arcuate surface section having a first edge and an opposite second edge, a top convex rounded surface and a bottom concave rounded surface, the second arcuate surface section having a first edge and an opposite second edge, a top concave rounded surface and a bottom convex rounded surface, the third arcuate surface section having a first edge and an opposite second edge, a top convex rounded surface and a bottom concave rounded surface, the first edge of the first arcuate surface section joined to the top edge of the transverse lip, the second edge of the first arcuate surface section joined to the first edge of the second arcuate surface section, and the second edge of the second arcuate surface section joined to the first edge of third arcuate surface section; c. an uppermost flat plate section having a first edge, a top surface and a bottom surface, the first edge of the uppermost flat plate section joined to the second edge of the third arcuate surface section; d. means by which the trowel is held attached at a location on at least one upper surface of the first arcuate surface section or the second arcuate surface section or the third arcuate surface section or the uppermost flat plate section; and e. the multi-rounded shape design of the concrete trowel is formed to be used in conjunction with an upper surface of a poured wet concrete structure at a location where at least one outward edge of the poured wet concrete structure abuts a frame, the transverse lip formed to be used in conjunction with the at least one outward edge of the poured wet concrete so that the transverse lip abuts a transverse side of the frame adjacent the outward edge of the poured wet concrete, and after the concrete trowel is pushed into the poured wet concrete to a depth that the bottom surface of the uppermost flat plate rests on the upper surface of the poured wet concrete and the first arcuate surface section, second arcuate surface section and third arcuate surface section lie within the poured wet concrete, the trowel is used in conjunction with the poured wet concrete by being pulled or pushed through the poured wet concrete such that the multi-rounded shape design of the first, second and third arcuate surface sections of the concrete trowel is formed into the poured wet concrete along at least one outward edge and the concrete resting on the upper surfaces of the first and second arcuate surface sections is discarded, leaving the multi-rounded shape design formed beneath the bottom surfaces of the first, second and third arcuate surface sections on an upper surface of the outward edge of the poured wet concrete structure.
