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 helix 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 helixes 16. A distal end segment 3 comprises a half helix ending in a sharp point 18. A main body portion helixes 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 helix. One preferred embodiment of the instant invention includes a main body portion 2 having three full helixes and a tip portion 3 comprising a half helix. 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 helix 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 wedge 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 helix enable the auger to cut through soil and debris for ease of rotation and deep ground penetration which includes the desirable features of helix 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 helix auger comprising round stock.

A preferred embodiment of the helical auger includes a top vertical portion for mounting an adapter or article to be supported thereon, a neck, a main body portion and a tip portion including a distal end forming a wedge or pointed segment. 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. As best illustrated in FIG. 6 the angle of the twists forming the flights of the helix of the main body portion are angled forming a plane at 30 degrees shown as angle “A”, however, the range could extend from 15 to 45 degrees.

As shown in FIGS. 7-8, the square bar stock is ⅜ inch in width and the distal end of the tip forming a penetrating or cutting edge is cut at a 33 degree angle, Angle “B”, forming an angled wedge of ⅝ inch in length forming a tip comprising a cutting wedge point 18 for easy insertion into rocky ground and grounds containing roots. It is contemplated that the angle of the wedge could range from 15 to 45 degrees depending upon the application. As shown in FIG. 8, the top section 1 is about 4 inches in length, the main body portion 2 comprises four helixes totaling seven inches in length, and the bottom section 3 is about 0.625 inches in length. A round or pointed tip 19 may also be utilized for particular types of substrates such as clay soil as shown in FIG. 9.

As shown in FIGS. 10-11, a “S-shaped” loop handle 30 may be integrally formed in a portion of the shaft of the auger extending above the ground. The handle top portion comprises at least one curved “S” shaped loop portion extending upwardly from a top distal end of the elongated rod, the “S” shaped loop portion including a first straight section extending outwardly from the elongated rod at a selected angle from the top distal end of the elongated rod. A first curved end section extends from a distal end of the first straight section returning 180 degrees extending inwardly toward the elongated rod forming a second straight section spaced apart, parallel, and in alignment with the first straight section extending past the elongated rod. A second opposing curved end section returns 180 degrees extending inwardly forming a third straight section extending from the second opposing curved end section spaced apart, parallel, and in alignment with the first straight section and the second straight section. A means for mounting an article to the top distal end of the top portion of the elongated shaft extending upward from the handle 30 may include a coupling or other mounting means for holding an supporting a selected article above the auger which anchors the support stand in the ground.
