TECHNICAL FIELD

The present invention relates to an having an integral handle and auger for supporting an object on an adapter in an upright position in the ground.

BACKGROUND OF THE INVENTION

The portable and reusable auger of the present invention can be used in combination with an integrated loop handle which can be installed in the ground with no tools by twisting and rotating the handle screwing the auger base into the ground.

SUMMARY OF THE INVENTION

A rotary auger for supporting or mounting and removably holding a articles or devices upright on the ground. The auger includes an upright rod with a helical spiral coil having a point at the lower distal end to be fixedly and removably screwed into the ground to support the in an upright position. The auger vertical shaft forms a cork screw or a helical coil formed in the bottom end. A looped handle may be formed integrally within the upper end of the shaft or rod extending from the auger with an vertically disposed “S” shaped loop formed in the center of the for enabling the screwing of the cork screw into the ground for vertical stabilization of the stake. The bottom helical coil ends with a sharp tip for easing the installation into the ground.

A preferred embodiment of the helical auger includes an inner bend diameter of a selected size such as ¼ inch bar stock, 3/16 inch bar stock, ½ inch bar stock, ⅝ inch bar stock, and ⅜ inch bar stock; a helical pitch of 2.0 for 3.5 revolutions; a variable pitch of 3.0 for 0.25 revolutions; and a pitch diameter of 1.375 inches having a helical pitch of 2.0.

It is an object of this invention to provide a portable and reusable auger which includes a helical coil or spiral having a point at a distal end.

It is an object of this invention to provide an integral crank handle for the purpose of screwing auger portion into the ground.

It is an object of the present invention to form an integral one piece auger having a helical spiral formed of stock having a square cross-section.

A preferred embodiment of the present invention comprises or consists of a rotary auger support comprising or consisting of a selected length of bar stock having a square cross sectional area including a bottom portion bent into a spiral, a vertical straight top portion, a neck portion extending downward from the vertical straight top portion, a main body portion extending downwardly from the neck portion, the main body portion comprising a helical spiral coil extending downward therefrom a selected distance, a distal end segment comprising a half spiral extending downward from the main body portion, and the distal end segment including a point for penetration into the ground.

Other objects, features, and advantages of the invention will be apparent with the following detailed description taken in conjunction with the accompanying drawings showing a preferred embodiment of the invention.

FIG. 6 is a bottom end view of the rotary auger support of FIG. 1.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

In accordance with the present invention, there is provided a rotary auger having a top end defining a vertical shaft The integral handle tie down rest is located at an upper end of a shaft extending upwardly from a spiral auger wherein the handle tie down rest can be bent at a selected angle to hold the tie down in a selected position with respect to the surface of the ground.

The rotary auger support 10 includes an above ground upright rod or shaft top portion 12 having an offset neck 14 connecting to a main body portion 2 comprising a plurality of spirals 16. A distal end segment 3 comprises a half spiral ending in a sharp point 18. A main body portion spirals 16 is comprised of bar stock having a square cross sectional area. The corners 21 or the square bar stock form cutting edges 23 when the stock is bent or formed into a spiral. One preferred embodiment of the instant invention includes a main body portion 2 having three full spirals and a tip 3 comprising a half spiral. The neck 14 of the rotary auger support 10 is angled inwardly toward the center of the main body portion 2 in order to center the shaft top portion 12 with respect to the main body portion 2. As best shown in FIG. 3, the neck portion includes a spiral first segment 31, a short straight inward angled second segment 32, a straight angled third segment 33, a short straight outward angled fourth segment 34, connecting to a vertical straight top segment 12 of a desired length.

The rotary auger 10 having a bottom portion for insertion into the ground comprises a helical coil 16 having a cutting edge which functions as a plurality of flights forming an auger 10 having cutting edges with a point 18 at the lower distal end to be fixedly and removably screwed into the ground 20 to support the 10 in an upright position.

The cutting edges of the spiral enable the auger to cut through soil and debris for ease of rotation and deep ground penetration which includes the desirable features of spiral flights. Moreover, the auger of the present invention is an improvement over the flights of conventional augers in that the narrow diameter of the stock and diameter of the flights enables the auger to cut and drill through small openings in rocky soil and wedge between rocks. Moreover, the rotary auger support 10 of the present invention can be rotatably inserted into hard clay which would resist penetration by an auger having flights or a spiral auger comprising round stock.

A preferred embodiment of the helical auger includes an inner bend diameter of a selected size such as ¼ inch bar stock, 3/16 inch bar stock, ½ inch bar stock, ⅝ inch bar stock, and ⅜ inch bar stock. The ⅜ inch rotary auger support includes an effective helical pitch of 2 for every 3.5 revolutions and a variable pitch of 3.0 for every 0.25 revolutions. The pitch diameter of 1.375 inches has a helical pitch of 2.0 inches.

It is contemplated that a handle (not shown) may be integrally formed in a portion of the shaft of the auger extending above the ground. One embodiment includes an integral crank handle rest loop which includes a first portion which extends outwardly from the rod at a selected angle, for instance a right angle or 90 degree angle. A second portion extends upwardly over, spaced apart from and in alignment with the first portion forming a curved or bent portion and extends past the shaft a selected equal distance from the shaft. A third top portion extends upwardly over, spaced apart from and in alignment with the second portion forming a curved or bent portion and extends to the shaft.

The foregoing detailed description is given primarily for clearness of understanding and no unnecessary limitations are to be understood therefrom, for modification will become obvious to those skilled in the art upon reading this disclosure and may be made upon departing from the spirit of the invention and scope of the appended claims. Accordingly, this invention is not intended to be limited by the specific exemplification presented herein above. Rather, what is intended to be covered is within the spirit and scope of the appended claims.
