Abstract:
1. A concrete trowel to form a shape into two opposite outward edges of a poured concrete structure with the poured concrete structure having an upper surface and a first outward edge abutting a first frame having a transverse side facing the first outward edge of the poured concrete structure and a second outward edge abutting a second frame member having a transverse side facing the second outward edge of the poured concrete structure, the concrete trowel comprising: a. a first transverse lip and a second transverse lip, the two transverse lips being spaced apart and parallel to each other, each transverse lip further comprising a top edge and a flat transverse outer surface; b. a multi-rounded shape design 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 concave rounded surface and a bottom convex 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 concave rounded surface section and a bottom convex rounded surface section, the first arcuate surface section joined to the top edge of the first transverse lip at a perpendicular angle and the second edge of the first arcuate surface section joined to the first edge of the second arcuate surface section, the second edge of the second arcuate surface section joined to the first edge of the third arcuate surface section, the third arcuate surface section joined at its second edge to the top edge of the second transverse lip at a perpendicular angle; c. 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; d. the bottom convex surface of each arcuate surface section forming a mirror image shape into the upper surface of the wet poured concrete as the trowel is moved through the wet poured concrete; e. the multi-rounded shape design of the concrete trowel is formed to be used in conjunction with the upper surface of the poured wet concrete structure at a location where the first outward edge of the poured wet concrete structure abuts the first frame, the first transverse lip formed to be used in conjunction with the first outward edge of the poured wet concrete so that the transverse lip abuts a transverse side of the first 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 top of the concave surface of each arcuate surface section 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 the first outward edge and the concrete resting on the upper concave surfaces of the first, second and second arcuate surface sections is discarded, leaving the multi-rounded shape design formed beneath the convex surfaces of the first, second and third arcuate surface sections on an upper surface of the first outward edge of the poured wet concrete structure, and f. the multi-rounded shape design of the concrete trowel is formed to be used in conjunction with the upper surface of the poured wet concrete structure at a location where the second outward edge of the poured wet concrete structure abuts the second frame, the second transverse lip formed to be used in conjunction with the second outward edge of the poured wet concrete so that the second transverse lip abuts a transverse side of the second 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 top of the concave surfaces of the first, second and third arcuate surface sections 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 the second outward edge and the concrete resting on the concave surfaces of the first, second and third arcuate surface sections is discarded, leaving the multi-rounded shape design formed beneath the concave surfaces of the first second and third arcuate surface sections on an upper surface of the second outward edge of the poured wet concrete structure.
