ABSTRACT:

BACKGROUND OF THE INVENTION
This invention relates to a cement slab surface beveling device, in particular, for beveling along the edge or end of a cement floor during the formation thereof.
Cement floors, in particular, are typically beveled along at least one end thereof especially garage floors where the ingress and egress to the garage floor are typically beveled because the floors are raised above the ground surface to substantially prevent water from getting on the garage floor from the outside, and the beveled surface not only facilitates runoff of the water but also allows vehicles to easily enter upon the garage floor.
One prior art is a TOOL FOR FORMING A BEVELED EDGE ON CEMENT WORK, U.S. Pat. No. 5,269,675, invented by Jerry W. Cox and issued on Dec. 14, 1993, and which comprises a tool body having a flat bottom surface for engaging a flat top surface of soft cement contained in cylindrical form and further having a downwardly-turned lip extending from a first end to a second end and being of a generally wedge-shaped structure.
Another known prior art is an INTERIOR EDGE-EDGER, U.S. Pat. No. 4,766,635, invented by Louis Devitis and issued on Aug. 30, 1988, and which comprises a flat inflexible rectangular plate shaped such the shorter leading edge and trailing edge curve upward and one of the longer edges has a central portion curving outward and downward.
Another known prior art is a CONCRETE SLAB SURFACE FINISHING TOOL, U.S. Pat. No. 4,737,097, invented by Joseph A. Cotugno and issued on Apr. 12, 1988, and which comprises a flat floor surface working area, a lip offset surface working area joined to the flat floor surface working area, a flat lip surface working area joined to the lip offset working area, and edge surface working area joined to the flat lip surface working area.
Another known prior art is a CONCRETE EDGING AND MARKING TOOL, U.S. Pat. No. 1,347,938, invented by H.F. Conelly and issued on Jul. 27, 1920, and which comprises a rectangular body, upward extending arms, inwardly extending pivot pins carried by the arms, the inner edges of the body having openings for rotatably receiving the pivot pins with one of the arms having inwardly extending lugs positioned on the opposite sides of the pivot pin, a hand grip connected to the arms, and a spring mounted about a bolt used to connect the hand grip to the arms.
Another known prior art is a TROWEL, U.S. Pat. No. 761,242, invented by George Meyers and issued on May 31, 1904, and which comprises a blade, a handle, and an attachment provided with ears adapted to enter orifices in the blade and held therein by clamps.
None of the prior art discloses or suggests a cement slab beveling device of the type described and claimed herein.
SUMMARY OF THE INVENTION
The present invention relates to a cement slab surface beveling device which comprises a plate-like support member having a bottom surface, a top side, a first end and a second end; and also comprises a handle member fastened to the top side of the plate-like member; and further comprises a tapered beveling member which extends downwardly from the bottom surface of the support member and which has an end, a bottom edge and a flat bottom surface which is angled relative to the flat bottom surface of the support member. Once the cement slab is poured and allowed to semi-harden, the user slides the cement slab surface beveling device along the edge of the floor with a second exposed flat portion of the bottom surface of the support member being movably supported upon the slab surface and a first exposed flat portion of the bottom surface at the second end of the support member being movably supported upon the cement slab frame and with a portion of the cement being removed by the tapered beveling member to form the beveled surface.
One objective of the present invention is to provide a cement slab surface beveling device which effectively reduces the amount of time to professionally form a beveled surface.
Another objective of the present invention is to provide a cement slab surface beveling device which allows the user to effectively and efficiently form a consistent and even beveled surface throughout.
Further objectives and advantages of the present invention will become apparent as the description proceeds and when taken in conjunction with the accompanying drawings wherein:
