DETAILED DESCRIPTION

(8) Reference throughout this specification to “one embodiment,” “an embodiment,” or similar language means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases “in one embodiment,” “in an embodiment,” and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment.

(9) Furthermore, the described features, structures, or characteristics of the invention may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to provide a thorough understanding of embodiments of the invention. One skilled in the relevant art will recognize, however, that the invention may be practiced without one or more of the specific details, or with other methods, components, materials, and so forth. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the invention.

(10) FIGS. 1-2 illustrate an isometric perspective view and a side perspective view respectively of a handheld portable aerator 100 in accordance with the present invention.

(11) The aerator 100 comprises an elongated shaft 102, a horizontal handle 104, and a base assembly 110 comprising an arcuate stabilizer 108, a baseplate 106, and a plurality of spikes 112.

(12) The arcuate stabilizer 108 defines an aperture (or bore) 114 through which the elongated handle 102 passes. The arcuate stabilizer 108 formed an U-shaped or arcuate beam which affixes at both ends (proximal and distal) to a top surface of the baseplate 106. In some embodiments, the arcuate stabilizer 108 is formed as a single integrated piece with the baseplate 106.

(13) In various embodiments, the base assembly 110 may comprise a plurality of arcuate stabilizers 108, each affixed at a different point on the perimeter or top surface of the baseplate 106.

(14) The elongated shaft 102 and the handle 104 comprise a T-shaped assembly in which the elongated shaft 102 is affixed at a midpoint to the handle 104. Distal and proximal ends of the handle 104 cantilever, or overhang, the elongated shaft 102, providing leverage to an operator seeking to twist the apparatus 100 or push down on it with two hands spaced apart.

(15) The elongated shaft 102 and handle 104 may be fabricated partially or entirely from a metal or metal alloy such as steel, titanium or leather; polymeric materials; or organic materials (such as wood, leather or resin).

(16) FIGS. 3-4 illustrate a front and lower perspective view of the base assembly of a handheld portable aerator 300 in accordance with the present invention.

(17) The baseplate 106 defines a plurality of bores 402 on a lower surface adapted to receive the spikes 112. The spikes are arranged in sets 406 of two. Each set 406 of spikes 112 is staggered (offset across the lower plane) from an adjacent set 406 of spikes.

(18) The baseplate 106 itself may not be rectangular from a lower perspective. As shown in FIG. 4, the baseplate 106 defines a plurality of recesses 608 around the perimeter of the baseplate 106 between sets 406 of spikes 112.

(19) Additionally, the baseplate 106 comprises a plurality of threaded bores 202 circumscribing the perimeter of the baseplate 106. These threaded bores 202 travel laterally into the sidewalls of the baseplate 106 and are adapted to receive bolts or screws for the purpose of securing spikes 112 in the bores 406. As such, the threaded bores 202 and the bores 406 interconnect within the baseplate 106 such that a screw inserted into a threaded bore 202 presses against, and forms a friction fit therewith, a proximal end of a spike 112 inserted into a bore 406. There is one bore 202 for each bore 406.

(20) In some embodiments, the arcuate stabilizer 108 comprises two L-shaped components 314a-b, each joined at the elongated shaft 102, each defining a semicircular recess adapted to circumscribed half of the outer surface of the elongated shaft 102, all to create nonuniform aeration across a ground surface 502.

(21) In some embodiments, the threaded bores 312 alternate between a recessed portion of the baseplate 106 and a nonrecessed portion of the baseplate 106 such that every odd threaded bore 312 traverses the baseplate from a differently-spaced lateral entry point that every even threaded bore 312.

(22) FIG. 5 is an environmental, side perspective view of a base of a handheld portable aerator 500 in accordance with the present invention.

(23) The apparatus 500 may be forced into a ground surface 502 as shown to aerate (or aerify) the surface.

(24) FIG. 6 is a lower perspective view of a base of a handheld portable aerator 600 in accordance with the present invention.

(25) In various embodiments, the baseplate 606 may be circular from a lower perspective (but otherwise substantially the same as baseplate 106). The spikes 112 may be arranged in circles around the lower surface of the baseplate 606 or may be irregularly spaced and irregularly-patterned in their arrangement on the baseplate 606. The baseplate 606 may also be triangular, square, polygonal, or irregularly-shaped. Even in the circular baseplate 606 may define the recesses 408 circumscribing the baseplate.

(26) The baseplate 606 may be fabricated from a metal or metal alloy, polymeric materials, or organic materials (such as wood, leather or resin).

(27) The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
