Vibratory concrete float

a technology of vibrating concrete and float, which is applied in the direction of portable power tools, roads, constructions, etc., can solve the problems of increasing finishing time, ineffectively reaching all the areas of the concrete surface, and cumbersome closing up the edges with a hand float, so as to reduce the finishing time and efficiently close up the concrete

Benefits of technology

[0005] Therefore, a hand float that can efficiently close up concrete without several passes, thereby, substantially decreasing the finishing time is needed.

Problems solved by technology

While the bull float is helpful in floating larger areas of concrete, it cannot effectively reach all the areas of the concrete surface, especially the peripheral edges of the concrete surface adjacent the forms, or where objects protrude upwardly from the concrete, such as pipes, building walls and the like.
Unfortunately, closing up these areas with a hand float requires passing the hand float back and forth over each area several times, substantially increasing the finishing time.
Thus, closing up the edges with a hand float is both cumbersome and time-consuming.

Embodiment Construction

[0014] The following detailed description illustrates the invention by way of example and not by way of limitation. The description clearly enables one skilled in the art to make and use the invention, describes several embodiments, adaptations, variations, alternatives, and uses of the invention, including what is presently believed to be the best mode of carrying out the invention.

[0015] As shown in FIGS. 1-2, an embodiment of the present invention, generally referred to as a vibratory concrete float 1, includes a body 3 secured to a removable handle 5 and a vibrator motor 7.

[0016] The body 3 is a generally rectangular plate having a bottom surface 9, a top surface 11, and a peripheral edge 13. In one embodiment, the body or plate 3 is preferably made of magnesium, but other materials such as aluminum, steel, plastic, or even wood may be used. For example, a magnesium plate 3 about 3 inches wide and about 16 inches long having a thickness of about ⅜ inch has worked well. A raise...

Abstract

The invention is a vibratory concrete float including a body and a vibrator operatively connected to the body, whereby the vibrator provides vibratory forces to the body. The float also includes a removable handle secured to the body with an integrated power source that electrically engages the vibrator when the handle is secured to the body and disengages the vibrator when the handle is removed from the body.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is related to U.S. Provisional Patent Application No. 60 / 494,200 filed Aug. 12, 2003 from which priority is claimed.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH [0002] Not Applicable. BACKGROUND OF THE INVENTION [0003] Concrete float devices for “floating” or “troweling” wet concrete are well known in the prior art. “Floating” is the first step in the finishing of concrete and is typically done immediately after screeding. Floating smoothes the surface of freshly poured concrete by depressing large aggregates and knocking down small ridges. For a small concrete pour, hand float devices are used to smooth the concrete surface. Generally, a hand float is a rectangular plate, typically made of wood, secured to a handle. For a larger concrete pour, bull float devices are used to smooth the concrete surface. Generally, a bull float is a large rectangular plate, typically made of magnesium, aluminum, steel or wood, secure...
