Ground anchor

Abstract

An anchor for securing an object to a ground surface includes a lower portion having a screw thread extending from a bottom end to a top end thereof. A neck portion extends above the lower portion, is devoid of the screw thread, and terminates at a top end thereof at a first collar. A first loop of a flexible tether is fixed about the neck portion and confined thereto by the first collar and the screw thread. A second opposing loop of the tether is sized to accept the lower portion therethrough, including the thread, but not the first collar. With the tether fixed about the object and the bottom end of the lower portion traversing the second loop as the anchor is screwed into the ground surface, the loops are fixed about the neck portion with the tether secures the object to the ground surface.

Claims

1. An anchor for securing an object to a ground surface, comprising: an elongated lower portion having a ground penetrating bottom end, a screw thread extending from the ground penetrating bottom end to a top end thereof; a neck portion extending above the top end of the elongated lower portion and devoid of the screw thread, the neck portion terminating at a top end thereof at a first collar; a flexible tether having a first end terminating in a first loop and a second end, of the flexible tether, opposite the first end, terminating in a second loop, the first loop fixed about the neck portion and confined thereto by the first collar and a second collar, the first collar and the second collar sandwiching at least a portion of the neck portion, the second loop sized to accept the elongated lower portion and the second collar therethrough but not the first collar; wherein, with the first loop fixed about the neck portion and confined thereto by the first collar and the second collar, the second loop is movable between a first position, without engagement with the elongated lower portion or neck portion, and a second position about the neck portion, adjacent the first loop by moving the second loop along a path from the ground penetrating bottom end and along the screw thread of the elongated lower portion.

2. The anchor of claim 1 wherein the first collar includes a tool engagement surface adapted to receive a rotational driving tool.

3. The anchor of claim 2 wherein the tool engagement surface is a screwdriver slot.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(13) Illustrative embodiments of the invention are described below. The following explanation provides specific details for a thorough understanding of and enabling description for these embodiments. One skilled in the art will understand that the invention may be practiced without such details. In other instances, well-known structures and functions have not been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

(14) Unless the context clearly requires otherwise, throughout the description and the claims, the words comprise, comprising, and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of including, but not limited to. Words using the singular or plural number also include the plural or singular number respectively. Additionally, the words herein, above, below and words of similar import, when used in this application, shall refer to this application as a whole and not to any particular portions of this application. When the claims use the word or in reference to a list of two or more items, that word covers all of the following interpretations of the word: any of the items in the list, all of the items in the list and any combination of the items in the list. When the word each is used to refer to an element that was previously introduced as being at least one in number, the word each does not necessarily imply a plurality of the elements, but can also mean a singular element.

(15) FIGS. 1, 8 and 9 illustrate an anchor 10 for securing an object 20, such as a sports goal, lawn chair, tent, picnic table, or the like to a ground surface 15.

(16) An elongated, rigid lower portion 30 has a ground-penetrating bottom end 32, a screw thread 40 extending from the bottom end 32 to a top end 38 thereof. A neck portion 50 extends above the top end 38 of the lower portion 30 and is devoid of the screw thread 40. The neck portion 50 terminates at a top end 58 thereof at a first collar 60. The lower portion 30 and neck portion 50 are preferably integrally formed from a rigid metal material.

(17) A flexible tether 70 has a first end 74 terminating in a first loop 80, and an opposing second end 76 terminating in a second loop 90. The first loop 80 is fixed about the neck portion 50 and confined thereto by the first collar 60 and the screw thread 40. The second loop 90 is sized to accept the lower portion 30 therethrough, including the thread 40, but not the first collar 60. The tether 70 is preferably a steel, stranded cable, or the like.

(18) As such, with the flexible tether 70 fixed about the object 20 and with the bottom end 32 of the lower portion 30 traversing the second loop 90 as the anchor 10 is screwed into the ground surface 15 until the lower portion 30 is substantially buried, the first and second loops 80,90 are fixed about the neck portion 50 with the tether looped around the object 20 to secure the object 20 to the ground surface 15 in a deployed configuration 100.

(19) Preferably the first collar 60 includes a tool engagement surface 110, such as a projecting polygon 113 adapted to receive a rotation driving tool 18, such as a socket tool 17 (FIG. 1). The tool engagement surface 110 may alternately be a screwdriver slot 111 (FIG. 4), a recessed polygon 112 adapted to receive a polygonal driving tool 19 (FIG. 3), or a handle crank 114 that also serves as the first collar 60 (FIG. 5).

(20) In some preferred embodiments, a tool engagement portion 120 extends upwardly from the top end 58 of the neck portion 50 and terminates at a top end 128 thereof at a second collar 130. The tool engagement portion 120 includes a tool engagement surface 110, such as an aperture 140 (FIGS. 6, 7 and 12) formed therethrough, adapted to receive the rotational driving tool 18, such as a rigid rod 150 fixed within the aperture 140. In such an embodiment, opposing ends 155 of the rigid rod 150 are deformed to prevent the ends 155 from traversing the aperture 140, or include a rivet 156 or other projecting feature, thereby slidably capturing the rigid rod 150 within the aperture 140. Preferably the tool engagement portion is integrally formed with the lower portion 30 and the neck portion 50.

(21) In some embodiments the top end 38 of the lower portion 30 includes a third collar 160. The first loop 80 of the tether 70 is captured between the first and third collars 60,160 and the second loop 90 is sized to receive therethrough the lower portion 30, screw thread 40 and the third collar 160, but not the first collar 60.

(22) The first and second loops 80,90 preferably substantially overlap when the anchor is in the deployed configuration 100, whereby a plastic cable tie 16 (FIG. 10), a padlock shackle 14 (FIG. 11), or the like can traverse each loop 80,90 to lock the loops together, inhibiting tampering with the anchor 10.

(23) While a particular form of the invention has been illustrated and described, it will be apparent that various modifications can be made without departing from the spirit and scope of the invention. For example, a few different tool engagement surfaces 110 and tool engagement portions 120 are described herein and illustrated in the drawings. However, other types of tool engagement surfaces 110 and tool engagement portions 120 could be utilized that facilitate the screwing of the anchor 10 into the ground surface 15. Accordingly, it is not intended that the invention be limited, except as by the appended claims.
