The tool has the ability to form one rounded edge at the bottom.
The Neece Patent is a design patent which protects the design of a particular concrete trowel.
The '634 DeVitis Patent is a hand tool which has a portion for showing how to make a rounded edge but this is just one bullet-nosed edge on the concrete.
The '634 DeVitis Patent discloses a hand tool for forming the interior edge of a cementitious surface. Once again, this is shown for the rounding features 8 and 6 of the tool. However, this once again is just one rounded portion.
The Charland Patent discloses a design patent for a fire house section hauler which has a rounded member for hauling a fire hose.
Finally, the Williams Patent is a circular edging tool for concrete. This patent is designed to have a circular concrete edge so that it can form the interior circle of a manhole frame.
None of the prior art patents disclose an apparatus to efficiently and effectively form a multiplicity of various rounded shapes into an edge of poured concrete. There is a significant need for such an apparatus.
SUMMARY OF THE INVENTION
The present invention is a novel tool which enables a mason or concrete worker to form very beautiful decorative designs into the edge of poured concrete which is used for a driveway, walkway, border of a planter, or other concrete structure having at least a partially flat surface and at least one side edge where the decorative design is formed. Through use of the present invention, any one of a multiplicity of multi-arcuate designs are formed into at least one side edge or outside edge or inside edge of a poured concrete slab to thereby significant beautify a driveway, walkway, planter border, or any other poured concrete structure.
It has been discovered, according to the present invention, that if a trowel is formed with a traverse lip which is intended to abut a frame border of a poured concrete structure and thereafter the trowel has a multiplicity of unique arcuate forms therein which extend to a flat surface structure at the uppermost part of the trowel, and the trowel has a receiving member for receiving a pole or handle formed into a location where the multi-rounded forms are located, then the trowel can be used to form beautiful arcuate designs into an edge of the poured concrete structure by aligning the transverse tip with the border of the structure, pressing the arcuate designs into the poured wet concrete until the flat edge rests on the flat portion of the poured concrete and pulling or pushing the trowel into and through the poured concrete and discarding the concrete which rests above the trowel, thereby leaving the beautiful arcuate designs formed into the edge of the poured concrete structure.
It is therefore a primary object of the present invention to create a trowel which is formed with a traverse lip which is intended to abut a frame border of a poured concrete structure and thereafter the trowel has a multiplicity of unique arcuate forms therein which extend to a flat surface structure at the uppermost part of the trowel, and the trowel has a receiving member for receiving a pole or handle formed into a location where the multi-rounded forms are located, so that the trowel can be used to form beautiful arcuate designs into an edge of the poured concrete structure by aligning the transverse tip with the border of the structure, pressing the arcuate designs into the poured wet concrete until the flat edge rests on the flat portion of the poured concrete and pulling or pushing the trowel into and through the poured concrete and discarding the concrete which rests above the trowel, thereby leaving the beautiful arcuate designs formed into the edge of the poured concrete structure.
Further novel features and other objects of the present invention will become apparent from the following detailed description, discussion and the appended claims, taken in conjunction with the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Although specific embodiments of the present invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the present invention. Various changes and modifications obvious to one skilled in the art to which the present invention pertains are deemed to be within the spirit, scope and contemplation of the present invention as further defined in the appended claims.
Referring to FIG. 1, there is illustrated a first embodiment of a pole operated trowel 10 of the present invention. The pole operated trowel 10 has a traverse side edge or lip 12 which has a bottom edge 14, a top edge 16 and an outward transverse surface 18. The top edge 16 of the lip 12 extends into the first arcuate surface section 22 of the multi-rounded design shaped portion 20 which has a first arcuate surface section 22 having a first edge 24, a second edge 26, a top rounded surface 28, a bottom rounded surface 30, a first side edge 32 and a second side edge 34; and a second arcuate surface section 36 which has a first edge 38, a second edge 40, a top rounded surface 42, a bottom rounded surface 44, a first side edge 46 and a second side edge 48. The top edge 16 of lip 12 extends into the first edge 24 of first arcuate surface section 22 and the second edge 26 of first arcuate surface section 22 extends into the first edge 38 of second arcuate surface section 36. Attached at a location on the upper surface of the multi-rounded design shaped portion 20 is an attachment means 50 which is rotatably connected to a pole receiving means 54. By way of example only, the attachment means 50 can be a transverse plate which is attached at a location adjacent the intersection of first arcuate surface section 22 and the second arcuate surface section 36. By way of example only, the pole receiving means 54 is attached to the transverse plate 50 by having an opening 52 in the transverse plate 50 and a threaded bolt 56 extending through an opening 60 in a collar 62 at the lower end of the pole receiving means 54 which is aligned with the opening 52 in the transverse plate and the nut 58 threaded onto the threaded bolt 56. The pole receiving means has an opening 64 to receive a pole. The second edge 40 of the second arcuate surface section 36 extends into the first edge 72 of an uppermost flat plate section 70 which also has a second or leading edge 74, a top surface 76, a bottom surface 78, a first side edge 80 and a second side edge 82.
The pole operated trowel 10 is shown in operation in FIGS. 3 through 6 to create beautiful decorative side edges on a poured concrete driveway 200. By way of example, there is illustrated a street 500, a driveway area 510, and a garage door 520 at the end of the driveway area 510 remote from the street 500. A border is formed around the concrete driveway area 510 which comprises a multiplicity of border members which are usually 2×4 pieces of lumber. A multiplicity of 2×4 lumber members 530 are positioned along a first side edge 512 of the driveway area 510 and rest between the side edge 512 a portion of lawn 542. A multiplicity of 2×4 lumber members 532 are positioned along an opposite second side edge 514 of the driveway area 510 and rest between the side edge 514 a portion of lawn 544. A multiplicity of 2×4 lumber members 534 are positioned along a first transverse edge 516 of the driveway area 510 and rest between the first transverse edge 516 and the floor beneath the garage door 520. A multiplicity of 2×4 lumber members 536 are positioned along an opposite second transverse edge 518 of the driveway area 510 and rest between the second transverse edge 516 and the street 500. Therefore, the lumber members 530, 532, 534 and 536 having respective interior sides 531, 533, 535 and 537 form a rectangular border round the driveway area 510 where the concrete is to be poured to form the driveway. The border members are formed to be the same height as the top surface 552 of the concrete 550. The concrete 550 is poured in the traditional manner. Typically, a cross-grid of metal such as wire rods rest on the ground over which the concrete is to be poured. The concrete 550 is poured into the driveway area 510 within the area surrounded by 2×4 lumber members 530, 532, 534 and 536. The mason 600 typically pushes and or pulls on a flattening tool which can be another 2×4 in order to provide a flat smooth upper surface 552 to the poured concrete 550.
The present invention pole operated trowel 10 is used after the concrete 550 has been poured and the upper surface 552 smoothed and flattened and while the concrete 550 is still wet. The mason 600 stands (or can kneel) to one side of the driveway area 510 and can stand on the lawn 542 or on a portion of the lumber members 530. The mason 600 aligns the pole operated trowel 10 such that its transverse side edge 12 is adjacent the interior edge 531 of the 2×4 lumber members 530 and the mason pushes the pole operated trowel 10 into the concrete 550 so that outward transverse surface 18 rests against the interior surface 531 of lumber members 532. The pole operated trowel 10 is pushed into the wet concrete 550 until the bottom surface 78 of flat plate such 70 rests on the top surface 552 of the poured concrete 550. From the perspective view illustrated in FIG. 1, it is now apparent that the first arcuate surface section 22 and second arcuate surface section 36 of the multi-rounded design shaped portion 20 are pushed into the wet concrete 550 and rest below the upper surface 552 of the concrete in the area bounded by the interior edge 531 of the 2×4 lumber members 530 and the width “W” of the multi-rounded portion 20 extending from first edge 24 to second edge 40. A pole 84 is retained within the opening 64 of pole receiving means 54 and the mason pulls the pole operated trowel 10 through the wet concrete 550. After every few inches, the desired multi-rounded shape is formed into the wet concrete in the area below the first and second arcuate surface sections 22 and 36 of the multi-rounded design shaped portion 20. The concrete on the respective top surfaces 28 ad 42 of the arcuate surface sections 22 and 36 piles up as shown in FIG. 5 and is thrown away as illustrated in FIG. 6. The discarded concrete is thrown into a trash receiving container (not shown).
The mason pulls the pole operated trowel 10 through the wet concrete 550 in this manner from the first transverse edge 516 adjacent the garage door 520 to the second transverse edge 518 adjacent the street 500. The pole operated trowel 10 can also be pushed in the opposite direction to smooth over the arcuate design left underneath the pole operated trowel 10. The collar 62 and threaded bolt 56 permit the angle of the pole 84 relative to the mason 600 to be adjusted to any angle so that the pulling angle of the design formed into the wet concrete can be of any height and longitudinal angle relative to the ground. The key innovation of the present invention over prior art trowels is that the present invention enables the mason to create any number of variations of arcuate designs into the edge 560 of the driveway 570 as illustrated in FIG. 7 so that an infinite number of multi-rounded designs of substantial aesthetic beauty can be formed into the side edge 560 of the driveway 570.
After one edge 560 is completed, the opposite edge of the driveway is embellished in the same manner while the concrete is still wet. The mason now stands (or can kneel) to the opposite side of the driveway area 510 and can stand on the lawn 544 or on a portion of the lumber members 532. The mason 600 aligns the pole operated trowel 10 such that its transverse side edge 12 is adjacent the interior edge 533 of the 2×4 lumber members 532 and pushes the pole operated trowel 10 into the concrete 550 so that outward transverse surface 18 rests against the interior surface 533 of lumber members 532. The pole operated trowel 10 is pushed into the wet concrete 550 until the bottom surface 78 of flat plate such 70 rests on the top surface 552 of the poured concrete. From the perspective view illustrated in FIG. 1, it is now apparent that the first arcuate surface section 22 and second arcuate surface section 36 of the multi-rounded design shaped portion 20 are pushed into the wet concrete 550 and rest below the upper surface 552 of the concrete in the area bounded by the interior edge 533 of the 2×4 lumber members 532 and the width “W” of the multi-rounded portion 20 extending from first edge 24 to second edge 40. A pole 84 is retained within the opening 64 of pole receiving means 54 and the mason pulls the pole operated trowel 10 through the wet concrete 550. After every few inches, the desired multi-rounded shape is formed into the wet concrete in the area below the first and second arcuate surface sections 22 and 36 of the multi-rounded design shaped portion 20. The concrete on the respective top surfaces 28 ad 42 of the arcuate surface sections 22 and 36 piles up as shown in FIG. 5 and is thrown away as illustrated in FIG. 6. The discarded concrete is thrown into a trash receiving container (not shown).
The mason pulls the pole operated trowel 10 through the wet concrete 550 in this manner from the first transverse edge 516 adjacent the garage door 520 to the second transverse edge 518 adjacent the street 500 or in the opposite direction from the street 500 to the location adjacent the garage door 520. The pole operated trowel 10 can also be pushed in the opposite direction to smooth over the arcuate design left underneath the pole operated trowel 10. The collar 62 and threaded bolt 56 permit the angle of the pole 84 relative to the mason 600 to be adjusted to any angle so that the pulling angle of the design formed into the wet concrete can be of any height and longitudinal angle relative to the ground.
The key innovation of the present invention over prior art trowels is that the present invention enables the mason to create any number of variations of arcuate designs into the opposite edge of the driveway 562 so that an infinite number of multi-rounded designs 580 of substantial aesthetic beauty can be formed into the side edge of the driveway 562. The competed designed 580 on both side edges 560 and 562 of the driveway 570 is illustrated in FIG. 7.
The preferred embodiment of the present invention is to have the pole 84 as this provides the most leverage to enable the mason 600 to pull or push the trowel 10 through the heavy concrete and lift the concrete laden trowel 10 to discard the concrete which rests above the trowel as it is pulled through the driveway. In an alternative embodiment illustrated in FIG. 2, the trowel 10A can be a hand operated trowel. The parts are identical to the parts in the pole operated trowel illustrated in FIG. 1 and are numbered the same, but instead of receiving a pole 84, the opening 64 receives a handle member 86. It is also within the spirit and scope of the present invention for the handle member to be of any shape and with the handle 86 rotatably mounted onto the body of the 10A as illustrated in FIG. 2 or mounted in a fixed orientation. The pulling and pushing operation using the handle operated trowel 10A is similar to the operation illustrated in FIGS. 3 through 6 but instead the mason 600 kneels on the lawn 542 or 544 and/or on the 2×4 members 530 and 532. This is a more difficult operation because the mason 600 does not have the leverage to pull and push the heavy concrete and throw it away as the mason 600 has when the mason 600 is standing. Therefore, while the hand operated trowel 10A is also within the spirit and scope of the present invention, the pole operated trowel 10 is the preferred embodiment for creating designs into a heavy concrete driveway or other heavy concrete surface.
While the present invention has been illustrated to create a multiplicity of beautiful arcuate designs into a concrete driveway, it will be appreciated that it can be used to create beautiful a multi-arcuate design in a the border of a flowerbed or other concrete structure on the ground. The same principles apply. The structure is surrounded with a wooden border or border made of other suitable material which will not adhere to concrete and the outward transverse surface 18 of the transverse side edge or lip 12 rests against the interior surface border (the interior surface of the border is defined as the surface of the border facing the concrete) while the bottom surface 78 of flat plate section 70 rests on the upper interior level of the structure and the sections of the multi-rounded design shaped portion 20 are pushed into the edge of the concrete structure and pulled and pushed through it as was described above to create the beautiful multi-rounded arcuate design shape into the border of the concrete structure.
It will be appreciated that the multi-rounded design illustrated in FIGS. 1 through 7 is only one of numerous multi-rounded designs that are within the spirit and scope of the present invention. Referring to FIG. 8, there is illustrated one of the numerous alternative multi-rounded designs that are within the spirit and scope of the present invention. In this alternative variation, instead of having two arcuate surface sections, there are three arcuate surface sections. It will be appreciated that it is within the spirit and scope of the present invention to have any number and shape of arcuate surface sections.
Referring to FIG. 8, there is illustrated an alternative embodiment of a pole operated trowel 110 of the present invention. The pole operated trowel 110 has a traverse side edge or lip 112 which has a bottom edge 114, a top edge 116 and an outward transverse surface 118. The top edge 116 of the lip 112 extends into the first arcuate surface section 122 of the multi-rounded design shaped portion 120 which has a first arcuate surface section 122 having a first edge 124, a second edge 126, a top rounded surface 128, a bottom rounded surface 130, a first side edge 132 and a second side edge 134; a second arcuate surface section 136 which has a first edge 138, a second edge 140, a top rounded surface 142, a bottom rounded surface 144, a first side edge 146 and a second side edge 148; and in this variation a third arcuate surface section 127 which has a first edge 129, a second edge 131, a top rounded surface 133, a bottom rounded surface 135, a first side edge 137 and a second side edge 139. The top edge 116 of lip 112 extends into the first edge 124 of first arcuate surface section 122, the second edge 126 of first arcuate surface section 122 extends into the first edge 138 of second arcuate surface section 136, and the second edge 140 of the second arcuate surface section 136 extends into the first edge 129 of third arcuate surface section 127. The second edge 131 of the third arcuate surface section 127 extends into the first edge 172 of an uppermost flat plate section 170 which also has a second or leading edge 174, a top surface 176, a bottom surface 178, a first side edge 180 and a second side edge 182.
In this variation of the pole operate trowel 110, attached at a location on the top surface 176 of the uppermost flat plate section 170 is an attachment means 150 which is rotatably connected to a pole receiving means 154. By of example only, the attachment means 150 can be a transverse plate which is attached at a location on the top surface 176 of the uppermost flat plate section 170. It will be appreciated that the attachment means can be on any upper surface of the pole operated trowel 110. By way of example only, the pole receiving means 154 is attached to the transverse plate 150 by having an opening 152 in the transverse plate 150 and a threaded bolt 156 extending through an opening 160 in a collar 162 at the lower end of the pole receiving means 154 which is aligned with the opening 152 in the transverse plate and the nut 158 threaded onto the threaded bolt 156. The pole receiving means has an opening 164 to receive a pole.
The pole operated trowel 110 is shown in operation in FIGS. 9 through 12 to create beautiful decorative side edges on a poured concrete driveway 400. By way of example, there is illustrated a street 605, a driveway area 610, and a garage door 620 at the end of the driveway area 610 remote from the street 605. A border is formed around the concrete driveway area 610 which comprises a multiplicity of border members which are usually 2×4 pieces of lumber. A multiplicity of 2×4 lumber members 630 are positioned along a first side edge 612 of the driveway area 610 and rest between the side edge 612 a portion of lawn 642. A multiplicity of 2×4 lumber members 632 are positioned along an opposite second side edge 614 of the driveway area 610 and rest between the side edge 614 a portion of lawn 644. A multiplicity of 2×4 lumber members 634 are positioned along a first transverse edge 616 of the driveway area 610 and rest between the first transverse edge 616 and the floor beneath the garage door 620. A multiplicity of 2×4 lumber members 636 are positioned along an opposite second transverse edge 618 of the driveway area 610 and rest between the second transverse edge 618 and the street 605. Therefore, the lumber members 630, 632, 634 and 636 Having respective interior sides 631, 633, 635 and 637 form a rectangular border round the driveway area 610 where the concrete is to be poured to form the driveway. The border members are formed to be the same height as the top surface 652 of the concrete 650. The concrete 650 is poured in the traditional manner. Typically, a cross-grid of metal such as wire rods rest on the ground over which the concrete is to be poured. The concrete 650 is poured into the driveway area 610 within the area surrounded by 2×4 lumber members 630, 632, 634 and 636. The mason 600 typically pushes and or pulls on a flattening tool which can be another 2×4 in order to provide a flat smooth upper surface 552 to the poured concrete 650.
The present invention pole operated trowel 110 is used after the concrete 650 has been poured and the upper surface 652 smoothed and flattened and while the concrete 650 is still wet. The mason 600 stands (or can kneel) to one side of the driveway area 610 and can stand on the lawn 642 or on a portion of the lumber members 630. The mason 600 aligns the pole operated trowel 110 such that its transverse side edge 112 is adjacent the interior edge 631 of the 2×4 lumber members 630 and pushes the pole operated trowel 110 into the concrete 650 so that outward transverse surface 118 rests against the interior surface 631 of lumber members 632. The pole operated trowel 110 is pushed into the wet concrete 650 until the bottom surface 178 of flat plate section 170 rests on the top surface 652 of the poured concrete 650. From the perspective view illustrated in FIG. 7, it is now apparent that the first arcuate surface section 122, the second arcuate surface section 136, and the third arcuate surface section 127 of the multi-rounded design shaped portion 120 are pushed into the wet concrete 650 and rest below the upper surface 652 of the concrete in the area bounded by the interior edge 631 of the 2×4 lumber members 630 and the width “W′” of the multi-rounded portion 120 extending from first edge 124 to second edge 131. A pole 184 is retained within the opening 164 of pole receiving means 154 and the mason pulls the pole operated trowel 110 through the wet concrete 650. After every few inches, the desired multi-rounded shape is formed into the wet concrete in the area below the first, second and third arcuate surface sections 122, 136 and 127 of the multi-rounded design shaped portion 120. The concrete on the respective top surfaces 128, 142 and 133 of the arcuate surface sections 122, 136 and 127 piles up as shown in FIG. 12 and is thrown away as illustrated in FIG. 13. The discarded concrete is thrown into a trash receiving container (not shown).
The mason pulls the pole operated trowel 110 through the wet concrete 650 in this manner from the first transverse edge 616 adjacent the garage door 620 to the second transverse edge 618 adjacent the street 605. The pole operated trowel 110 can also be pushed in the opposite direction to smooth over the arcuate design left underneath the pole operated trowel 110. The collar 162 and threaded bolt 156 permit the angle of the pole 184 relative to the mason 600 to be adjusted to any angle so that the pulling angle of the design formed into the wet concrete can be of any height and longitudinal angle relative to the ground. The key innovation of the present invention over prior art trowels is that the present invention enables the mason to create any number of variations of arcuate designs into the edge 660 of the driveway 670 as illustrated in FIG. 14 so that an infinite number of multi-rounded designs of substantial aesthetic beauty can be formed into the side edge 660 of the driveway 670.
After one edge 660 is completed, the opposite edge of the driveway is embellished in the same manner while the concrete is still wet. The mason now stands (or can kneel) to the opposite side of the driveway area 610 and can stand on the lawn 644 or on a portion of the lumber members 632. The mason 600 aligns the pole operated trowel 110 such that its transverse side edge 112 is adjacent the interior edge 633 of the 2×4 lumber members 632 and pushes the pole operated trowel 110 into the concrete 650 so that outward transverse surface 118 rests against the interior surface 633 of lumber members 632. The pole operated trowel 110 is pushed into the wet concrete 650 until the bottom surface 178 of flat plate section 170 rests on the top surface 652 of the poured concrete. From the perspective view illustrated in FIG. 8, it is now apparent that the first arcuate surface section 122, the second arcuate surface section 136 and third arcuate surface section 127 of the multi-rounded design shaped portion 210 are pushed into the wet concrete 650 and rest below the upper surface 652 of the concrete in the area bounded by the interior edge 633 of the 2×4 lumber members 632 and the width “W′” of the multi-rounded portion 120 extending from first edge 124 to second edge 131. A pole 184 is retained within the opening 164 of pole receiving means 154 and the mason pulls the pole operated trowel 110 through the wet concrete 650. After every few inches, the desired multi-rounded shape is formed into the wet concrete in the area below the first, second and third arcuate surface sections 122, 136 and 127 of the multi-rounded design shaped portion 120. The concrete on the respective top surfaces 128, 142 and 133 of the arcuate surface sections 122, 136 and 127 piles up as shown in FIG. 12 and is thrown away as illustrated in FIG. 13. The discarded concrete is thrown into a trash receiving container (not shown).
The mason pulls the pole operated trowel 110 through the wet concrete 650 in this manner from the first transverse edge 616 adjacent the garage door 620 to the second transverse edge 618 adjacent the street 605 or in the opposite direction from the street 605 to the location adjacent the garage door 620. The pole operated trowel 110 can also be pushed in the opposite direction to smooth over the arcuate design left underneath the pole operated trowel 110. The collar 162 and threaded bolt 156 permit the angle of the pole 184 relative to the mason 600 to be adjusted to any angle so that the pulling angle of the design formed into the wet concrete can be of any height and longitudinal angle relative to the ground.
The key innovation of the present invention over prior art trowels is that the present invention enables the mason to create any number of variations of arcuate designs into the opposite edge of the driveway 662 so that an infinite number of multi-rounded designs 680 of substantial aesthetic beauty can be formed into the side edge of the driveway 662. The competed designed 680 on both side edges 660 and 662 of the driveway 670 is illustrated in FIG. 14.
The preferred embodiment of the present invention is to have the pole 184 as this provides the most leverage to enable the mason 600 to pull or push the trowel 110 through the heavy concrete and lift the concrete laden trowel 110 to discard the concrete which rests above the trowel as it is pulled through the driveway. In an alternative embodiment illustrated in FIG. 9, the trowel 110A can be a hand operated trowel. The parts are identical to the parts in the pole operated trowel illustrated in FIG. 8 and are numbered the same, but instead of receiving a pole 184, the opening 164 receives a handle member 186. It is also within the spirit and scope of the present invention for the handle member to be of any shape and with the handle 186 rotatably mounted onto the body of the 110A as illustrated in FIG. 9 or mounted in a fixed orientation. The pulling and pushing operation using the handle operated trowel 110A is similar to the operation illustrated in FIGS. 10 through 13 but instead the mason 600 kneels on the lawn 642 or 644 and/or on the 2×4 members 630 and 632. This is a more difficult operation because the mason 600 does not have the leverage to pull and push the heavy concrete and throw it away as the mason 600 has when the mason 600 is standing. Therefore, while the hand operated trowel 110A is also within the spirit and scope of the present invention, the pole operated trowel 110 is the preferred embodiment for creating designs into a heavy concrete driveway or other heavy concrete surface.
In an additional embellishment to the present invention, the bottom surface of the trowel 10 can have a decorative design formed into the bottom surface of the trowel 10. Therefore, after the operation is completed as illustrated in FIGS. 7 and 14, and while the concrete is still wet, the mason stamps the decorative design into the wet concrete so that the final finished driveway has the decorative design stamped into it and therefore the final driveway has a beautiful rounded design with a decorative design stamped into it. By way of example only, one type of decorative design is a brick pattern 900 as illustrated in FIG. 17. The brick pattern 900 is formed into a second trowel 10B which is the same as trowel 10 however the bottom surfaces 30 and 44 and the bottom surface 78 of the uppermost flat plate section 70 and the locations between these areas on the bottom of the trowel all have the decorative design formed into them. The decorative brick design 900 is illustrated in FIG. 17 and the side view of FIG. 18 shows how the decorative brick design 900 is formed into the underside of the concrete trowel 10B. After the operation to create the rounded design into the driveway is completed, as illustrated in FIG. 7, and while the concrete is still wet, the mason goes to the area adjacent either the street or the garage door and through a vertical downward action, stamps the decorative pattern into the wet concrete, lifts up the trowel 10B and makes another stamping action adjacent the first stamping, and through a repetitive process stamps the brick design 900 into the entire multi-rounded concrete design which was formed on the side edges of the driveway. In addition, the design can also be under the flat plate surface 78 and therefore the design extends into the flat area of the driveway adjacent the multi-rounded design area. The final finished design 580A has the brick pattern formed into both side edges 560 and 562 and also into the driveway 570 in the area adjacent the side edges 560 and 562 as illustrated in FIG. 19. It will be appreciated that the brick design is only one of many numerous designs which can be used, which includes flowers, animals, artwork, etc. The same stamping concept can be formed into other applications of the present invention including flowerbeds and the tabletop as discussed below.
It is also possible to use any variation of the present invention to create a multi-rounded edge on a poured concrete tabletop instead of a driveway. As illustrated in FIG. 15, the concrete is poured onto an elevated structure 800 having a smooth flat surface 810 which is surrounded by four 2×4 beams; beam 830 having interior side edge 831, beam 832 having interior side edge 833, beam 834 having interior side edge 835, and beam 836 having interior side edge 837. To form a multi-rounded design onto one or more edges of the concrete tabletop 820, the hand operated version of the trowel such as that illustrated in FIGS. 2 and 9 is used. The outward transverse surface 18 or 118 of lip 12 or 112 is aligned against an interior surface of a beam after the wet concrete tabletop 820 has been poured and the multi-rounded sections 20 or 120 are pushed into the wet concrete tabletop 820 until the bottom surface 78 or 178 or the uppermost flat plate section 70 or 170 rests against the flat top surface 822 of the poured concrete 820. The trowel 10A or 110A is then pulled or pushed through the edge of the concrete with the concrete on top of the trowel being discarded as previously discussed so that the beautiful multi-rounded design 830 is now formed into the edges of the finished tabletop as illustrated in FIG. 16.
