Aerator Description
BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to lawn aerators and more particularly pertains to a new lawn aerator with an array of aeration posts for providing a superior device for spot aerating a lawn.

2. Description of the Prior Art

The use of lawn aerators is known in the prior art. More specifically, lawn aerators heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.

Known prior art lawn aerators include U.S. Pat. No. 4,819,735; U.S. Pat. No. 3,881,553; U.S. Pat. No. Des. 309,242; U.S. Pat. No. 4,858,697; U.S. Pat. No. 5,207,466; and U.S. Pat. No. 4,204,576.

In these respects, the according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides a lawn aerator with an array of aeration posts primarily developed for the purpose of providing a superior device for spot aerating a lawn.

SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known types of lawn aerators now present in the prior art, the present invention provides a new lawn aerator with an array of aeration posts construction wherein the same can be utilized for providing a superior device for spot aerating a lawn.

The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new lawn aerator with an array of aeration posts apparatus and method which has many of the advantages of the lawn aerators mentioned heretofore and many novel features that result in a new lawn aerator with an array of aeration posts which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art lawn aerators, either alone or in any combination thereof.

To attain this, the present invention generally comprises a thin square base plate with a top surface, a bottom surface and a periphery formed therebetween. As shown in FIGS. 1 & 2, the top surface has a plurality of vertically oriented triangular supports coupled thereto. Each of such triangular supports extends between a center of the base plate and an associated one of the corners thereof. A tubular sleeve is coupled to the top surface of the base plate at a center thereof. As shown in FIGS. 1 & 3, the tubular sleeve is coupled to inboard edges of the triangular supports and further has a threaded interior surface. Next provided is an array of posts coupled to the bottom surface of the base plate and extending downwardly therefrom. The posts are arranged to define four rows and four columns. Each post includes an upper extent with a inverted frusto-conical configuration and a lower extent having an inverted conical configuration. Finally, an elongated cylindrical handle is provided having a top end with an elastomeric grip formed thereon. A bottom end is equipped with a plurality of threaded grooves formed thereon. Such grooves allow for the screwably coupling of the handle within the tubular sleeve such that the handle extends perpendicularly with respect to the base plate.

There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIGS. 1 through 4 thereof, a new lawn aerator with an array of aeration posts embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

The present invention, as designated as numeral 10, includes a thin square base plate 12 with a top surface, a bottom surface and a periphery formed therebetween. In the preferred embodiment, the base plate has a surface area of 64 square inches. As shown in FIGS. 1 & 2, the top surface has a plurality of vertically oriented triangular supports 14 coupled thereto. Each of such triangular supports extends between a center of the base plate and an associated one of the corners thereof. An upper edge of such supports extends downward from a center of the base plate to the periphery thereof.

A tubular sleeve 18 is coupled to the top surface of the base plate at a center thereof. As shown in FIGS. 1 & 3, the tubular sleeve is coupled to inboard edges of the triangular supports and further has a threaded interior surface.

Next provided is an array of posts 20 coupled to the bottom surface of the base plate and extending downwardly therefrom. Each post ideally has a height of about 2 inches and a diameter ranging between 7/16 of an inch to 5/16 of an inch. The posts are arranged to define four rows and four columns. Preferably, the posts are spaced from the periphery 1/2 a length between each pair of adjacent posts. Each post includes an upper extent 22 with a inverted frusto-conical configuration and a lower extent 24 having an inverted conical configuration. As shown in FIG. 2, the upper extent of each post has a length of at least 8 times that of the lower extent.

Finally, an elongated cylindrical handle 26 is provided having a top end with an elastomeric grip 28 formed thereon. An exterior surface of the grip is smooth. A bottom end of the handle is equipped with a plurality of threaded grooves 30 formed thereon. Such grooves allow for the screwably coupling of the handle within the tubular sleeve such that the handle extends perpendicularly with respect to the base plate. In the preferred embodiment, the handle has a height of about 45 inches and a diameter of about 1 inch.

During use, a user may insert the posts within the ground and wiggle the same by gyrating the handle. The present invention is thereafter removed from the ground and aeration ensues. It should be noted that the present invention is ideal for aerating hard to reach areas.

As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
