Description

Improved ground anchor with guiding ribs

The present invention relates to a ground anchor, and in particular to a ground anchor that is driven into the ground to tow a type of fastening bolt or anchor cable attached to one of the top sides of the anchor, the anchor having an adaptation The anchor is caused to rotate in the ground to a surface of the main body that is substantially perpendicular to one of the positions of the attached anchor or anchor cable.

Drive in and rotate or slide anchors are well known. Anchors of this type are usually driven into the ground by a driving rod that can be easily impacted by a hammer for smaller anchors or by a hand drill or hydraulic for larger anchors. / Pneumatic driver. After the anchor has been driven into a desired position, it will be pivotally attached to one of the anchor rear anchor lines, anchor cables, anchor chains, anchors or the like (sometimes referred to herein as anchor cables) tension. This causes the anchor to drill into the ground at a rear end and then rotate until the main longitudinal body of the anchor is generally perpendicular to the direction of the anchor cable. This anchors the anchor and can then attach one of the devices or structures to be anchored to the anchor cable or pole, wherein the anchor is in a load and "locked" position.

The drive-in and rotary anchors are generally comprised of two types, a first type being larger, such as shown in U.S. Patent No. 6,237,289, the disclosure of which is incorporated herein by reference. The anchor has a body portion extending longitudinally from the anchor, wherein a top surface has a raised portion with one of the attachment means for attachment of a fixed anchor cable or anchor, the fixed anchor cable or anchor Drive into the ground along with the anchor and when the anchor cable or anchor is pulled back after the anchor has been driven to its final depth, the fixed anchor cable or bolt will be at its junction with the anchor The anchor body rotates. The anchor is provided with laterally projecting wings that greatly increase the cross-sectional dimension of the anchor and that extend generally adjacent to the anchor but generally extend from one of the leading edges to a generally adjacent but spaced apart one of the trailing edges or the anchor Adjacent but generally spaced apart, one of the leading edges points generally adjacent but separated by a trailing edge extending outwardly from the body portion to the sides. The anchor wings may be retracted at their leading edges and have individual spaced apart chiseled or sharpened surfaces (typically resulting in a radius edge) to reduce the resistance to initial forward movement of the wings. And contributed to the anchor into the ground. The front end or the forward end of the anchor may also have a series of chiseled sections of the retracted section or may be cross-shaped or T-shaped, or in some instances, may have a rounded or passivated leading edge . In a preferred embodiment of the large winged anchor, the forward edge is formed at the intersection of two plate-like members projecting forwardly from the body of the anchor at right angles to each other, each of the plate members The result is a series of chiseled or sharpened edges of the retracted segments. The rear end of the anchor is provided with an everted lip which may be provided on the anchor body or may be provided at the rear end of the wing by the everted trailing edge. The anchor usually has a hit point. In the embodiment of the anchor shown in the '289 patent, the anchoring of the anchor is performed through a central opening extending longitudinally into the anchor body to one of the points in front of the intermediate length of the anchor. A driving rod is inserted into the hole and can be impacted by a large hammer, a hydraulic/pneumatic hammer or a hydraulic press, a ram or the like to drive the anchor into the ground. This technique is aware of other types of drive fasteners that sometimes do not utilize one of the holes in the center section but can engage the rear of the anchor body and the trailing edge or other portion of the wing to drive the front edge of the anchor forward.

For example, U.S. Patent No. 7,534,073, the disclosure of which is incorporated herein by reference in its entirety in its entirety in its entirety in the the the the the the the the In an anchor of the type, the body itself may be substantially tubular (as shown in U.S. Patent No. 4,096,673, the disclosure of which is incorporated herein incorporated by reference in its entirety) in Ribs 80, 81 such as shown in the '073 patent, which extend a small distance from the body. Such anchors may have a rounded or passivated front end as taught in U.S. Patent No. 7,789,594, the disclosure of which is incorporated herein. These smaller anchors are well known in the art. The assignee's trademark of this anchor, Duckbill It is famous and sold in most countries of the world.

Large winged anchors available in many sizes (by the assignee's trademark Manta Ray And Sting Ray Said) is also a best seller.

Although the change in soil conditions, the presence of a small portion (section) of harder soil segments or small rock locations, or the like may have a tendency to cause the anchor to deviate from the straight path or cause the anchor to rotate about its longitudinal axis, the wings and To a lesser extent, the ribs on the side of the smaller anchor assist in straightening into the anchor. While prior art wings and ribs are generally effective in resisting this torsional rotation, the wings and ribs created from the leading edge are less effective in preventing the nose and leading edge from deviating upward or downward relative to the longitudinal axis. . Providing one of the effects of one of the techniques that does not have a significant adverse effect on the driving force required to drive the anchor but assists in maintaining straight ingress and may have the possibility of reducing one of the leading edges to rise or fall vertically .

The present invention provides a small sized complementary guiding rib extending longitudinally along the body and positioned substantially parallel to the wing (for a winged anchor) or a primary side rib (for a smaller Duckbill type anchor) and by the primary rib The complementary guide ribs in front of the wings extend to a position in front of the body portion but are spaced apart from the leading edge to improve the directional stability of the movement of the anchor during the driving. The complementary guide ribs form a longitudinally extending passage or groove between the wings and the complementary guide ribs or between the primary ribs and the complementary guide ribs. Although two complementary guiding ribs can be placed under the wings or the main ribs, or above the main ribs, it is also contemplated that one rib is placed on one side and one rib is placed on Below the other side. In some applications, the complementary guiding ribs can be placed above and below the wings or main ribs.

The complementary guiding ribs are preferably V-shaped in cross section and relatively small in protrusion from the side of the anchor.

In one embodiment of the invention, the anchor includes a body portion that extends longitudinally along the direction in which the anchor is driven into the ground and that has a leading edge and a trailing edge. The body has a pair of opposing side projections extending outwardly from a central body portion of the body. A complementary projection or set of guiding ribs is positioned to be closely spaced from the first set of projections to define a generally narrower recess between the first set of projections and the second set of projections. The second set of protrusions extends only a small portion of the width of the body.

In another embodiment of the invention, the anchoring system is comprised of a body portion having a raised projection on a top surface, the raised projection adapted to an anchor line (which can be a bolt, an anchor One of a cable, a chain or an anchor is pivotally connected. The anchor body has a leading edge and a trailing edge and is provided with protruding wings extending outwardly from the side of the body. The wings are thinned from top to bottom relative to the anchor body and the wings become thinner and further away from the anchor body sides. A complementary guide rib set extending from a side of the anchor body is positioned to be relatively closely spaced from a surface of the wing such that a groove is defined between the complementary guide rib and the wing surface, the complementary guide The ribs extend from adjacent but spaced apart leading edges to the adjacent trailing edge and project a smaller amount from the anchor body, whereby the complementary guiding ribs provide little drag to the anchor but cooperate with the wings Stabilize the driving direction of the anchor that resists rotation.

In a further embodiment of the present invention, a driving and rotating anchor is provided with an anchor body having a front end and a rear end, wherein the rear end has an everted lip; the anchor is at the front end and the rear The middle of the end but generally closer to the rear end having a fastener segment for rotatably attaching to one of the anchor wires, extending from the side of the anchor body only a fraction of the width of the anchor body and at Between the first and second spaced apart protruding side ribs defining a recess therebetween, the ribs being a major longitudinally extending rib pair positioned between the top and the bottom of the anchor and substantially The ribs are closely spaced and are formed from abutting but spaced apart leading edges to one of the adjacent trailing edges of complementary protruding guiding rib pairs. One or both sets of ribs may be V-shaped in cross-section whereby the width of the groove increases away from the anchor body.

One primary object of the present invention is to improve a prior art drive-in and rotary ground anchor equipped with side projections that are closely positioned to the main side of the anchor by providing a complementary side projection set And extending longitudinally from the anchor along with the main side projection to define a recess between the sets of projections, the length of the complementary guide projections protruding from the anchor body relative to the width of the anchor body The middle is smaller.

These and other objects of the present invention will be apparent from the description of the preferred embodiments of the <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; Other designs and teachings of the present invention are applicable to such other designs.

As shown in FIG. 1, one of the types of anchors disclosed in U.S. Patent No. 6,237,289 is generally referred to as having one of the leading edges 11 extending from a body portion 10 and a pivoting or pivoting anchor. The body portion can have a generally circular section 12 located in front of a rear end 13. The lateral projecting wings 15 and 16 project from the side of the body portion 10 and may have chamfered leading edges 17 and 18 that are retracted to provide a series of slanted wing leading edges. The leading edge of the anchor 11 may itself be formed by a single protruding front end member 20 (which may result in a sharpened pointed or chiseled leading edge) or, more preferably, a pair of orthogonally positioned plates 20 and Formed 21, one of the plates (21) being at a right angle perpendicular to the wings 15 and 16, and the other of the plates being horizontal and at the leading edge of the wings aligned generally with the wings 17, 18 extended forward. Each of the plates 20 and 21 can result in a sharpened or chiseled surface or a plurality of smaller backed step surfaces, best shown as 30 in FIG.

The rear end of the anchor can be provided with an opening 25 that terminates into the body section 12 and can be inserted into a drive rod. The top surface of the body portion has a raised boss projection or projection 40 that extends over a top surface 41 of the body portion 12 and that contains a structure for attachment of an anchor cable. The term "anchor cable" is used herein to refer to any of a wide variety of structures that extend the self-anchor to the surface of the ground after the anchor has been placed and can then form the basis for attachment to the structure in which the anchor is fixed. By. In the illustrated embodiment, the structure for securing the anchor cable extends through one of the hook and loop pin openings 60 of one of the narrowed portions 61 of the projections 40. The projection 40 has a second section 41 located in front of the narrowed section 61, which may be wedge-shaped or frustoconical in shape at its front or otherwise designed to push the anchor into it The material is kept away from the point of contact with the anchor cable. In the illustrated embodiment, an anchor cable to be terminated through the ring opening 60 or opening 60 may be provided for hooking to an anchor cable, an anchor chain or a series of threaded rod segments. One of the ring pivots, all of which are well known in the art. The particular configuration shown herein, the use of a hole or opening is only one known way of attaching an anchor cable and those skilled in the art will be familiar with many types of structures, such as one of the grooves and blind holes. The T-shaped end on the end is formed in the protrusion 40 and the like. Many other intrusion mechanisms are known to the art, including a specially shaped, terminating rod that terminates at one end of the anchor and can have a slot for receiving the wing, or even for The rod is screwed to the anchor for a threaded connection.

Preferably, the point of pivotal connection to the anchor cable or anchor is approximately at the center length of the anchor but may be slightly behind or in front of the other. The anchor is provided with an everted lip 70 at its trailing edge so that after the anchor cable has been driven into the ground by a driving rod, the everted lip will be dug into the anchor by tensioning the anchor cable The side wall of the open channel and due to the longitudinal eccentric connection to the anchor cable pivots or rotates the auxiliary anchor to a point where the anchor line protrudes substantially perpendicular to the longitudinal length of the anchor. An upward pressure applies to place the anchor, and at that point, the anchor will be "locked" into its maximum holding position. Although in the preferred embodiment illustrated herein, an everted lip is shown extending rearwardly and outwardly from a blind hole at the rear end, other structures that cause rotation are also well known and may be combined or substituted. Use on the lips. One such configuration would provide an angled overturned surface on the rear end of the wing. In another configuration, a pivoting section of the anchor can be provided, which itself can have a rear end for engaging the ground when the anchor is retracted while the other portions of the anchor remain unrotated. All such structures are referred to herein as inswing and pivoting anchors.

In accordance with the teachings of the present invention, the anchor is provided with at least two longitudinally extending complementary guiding ribs 80 and 81 that project to the side of the anchor and are positioned below the wings. The forward end of the complementary guide rib 84 can extend forward from the wing, for example, as shown in FIG. In the preferred embodiment, the complementary guide ribs extend longitudinally rearwardly to a rear end 85 which may follow the ends of the wings. The complementary guiding ribs are preferably V-shaped in cross section. As best seen in Figure 8, the complementary guide ribs define grooves 90, 91 between the top surface of the ribs 80, 81 and one of the bottom surfaces of the wings. When the anchor is driven into the soil (which can be clay, clay, sandy loam, etc.), the anchor will form a string of soil material that is compressed by the grooves in the anchor.

The provision of the grooves and complementary guiding ribs helps prevent the leading edge of the anchor from being lifted or pushed down when the anchor is driven. This beneficial result can be achieved using protrusions that are smaller in length from the anchor projection and that have a smaller profile thickness. For example, in an anchor having a trailing edge of about 366 mm to the leading edge length and having a span of about 178 mm, the complementary guiding rib having a V-shaped profile can be self-anchored sidewall surface Extend 10 mm or less toward the rear end of the anchor. This will be less than 10% of the side projections of the opposing wings. The complementary protrusions may extend further toward the leading edge of the anchor, if desired. In this configuration, the body of the anchor can typically have a diameter of about 51 mm. The projections can be positioned up to 10 mm from the lower surface of the wing adjacent the anchor body, or can be positioned at a greater distance for this size or for larger anchors. However, it is believed that the desired result can be achieved by means of relatively small grooves formed between the main ribs or the wings and the complementary guiding ribs without severely adversely affecting the rotation to the locked position.

It should be understood that these specifications are merely illustrative and other sizes may be chosen, further understanding that the complementary guiding ribs are smaller and therefore do not require any significant additional driving force when inserting the anchor into the ground. Due to the V-shaped profile, the complementary guide ribs also do not provide any significant resistance to rotation about the longitudinal axis of the anchor, as the function is produced by the wings. The leading ends of the ribs may be tapered or "carved".

In the illustrated embodiment, both of the complementary guide ribs 80, 81 have been illustrated positioned below the wings 15 and 16. If desired, the complementary guide ribs can be positioned over the wings without obstructing the anchor cable attachment under the condition that there is sufficient vertical space for the complementary guide ribs along the length of the body. The ribs may also be provided one above one wing and one on the other under the other wing. In a further form, the ribs can be positioned above and below the wings.

Figure 10 illustrates what is commonly referred to as Duckbill One of the anchors is a smaller anchor that can also have a multi-edge front surface 100 and an everted lip rear surface 101, wherein a raised boss or projection 102 and a top portion thereof having a narrower portion 103 are formed for One of the anchor cables is attached to point 104. The anchor of this type typically includes a generally tubular body 105 that is forwardly directed toward the front end of the frustoconical section 106 from which the forward projections 110 and 111 of the slab-shaped tooth shape are retracted. termination. For example, a longitudinally extending primary rib 120 can be provided on each side of the body, as shown in U.S. Patent No. 5,734,073, the disclosure of which is incorporated herein by reference. The body projects to a distance of about 20% or less of the width of the body. Since the range of such anchors can range from relatively small (ie, 2 inches overall) to anchors 6 inches in length, the scope of the body can be approximated One inch in diameter to about 1 One inch in diameter. It is also known to be larger.

Secondary guide ribs 122 are provided below main ribs 120 in accordance with the teachings of the present invention. It should be understood that although not shown in the drawings, an additional complementary guide rib 122 will be positioned from the illustrated side on the other side of the anchor, as will be the other primary rib 120. The complementary ribs may extend forward from the front end 123 of the primary rib 120, as shown at 124, wherein the rib slides inwardly and is formed in front of the frustoconical surface 16. The ribs may then extend outwardly past one or more of the rectilinear steps or, as shown, may terminate approximately the same as the last horizontal retraction step 125.

Either of the complementary ribs will preferably be no more than 20% or less of the width of the anchor body. As mentioned above, it is known that there is a leading edge configuration other than the illustrated step back, and as shown, for example, in U.S. Patent 7,789,594, the front end can be rounded or passivated. Again, the complementary guiding ribs are preferably spaced apart from the lower surface of the primary rib (which may be considered to be similar to the wing of the earlier illustrated embodiment) so as to also provide between the ribs extending longitudinally from the body of the anchor. A groove 130 is formed in the groove when the anchor is forced through the soil and leaves a string of ridges on the inner surface of the soil. The provision of complementary guiding ribs and the provision of the grooves between the ribs and the wings or main ribs cooperate to facilitate linear entry of the anchor into the soil pores formed by the channels of the anchor. As in the case of a winged embodiment, the complementary ribs may be positioned above the primary ribs, on one side on the other side and on the other side below, or on the top and below, in which case a groove will be provided .

While two separate embodiments of the drive and pivot anchor have been selected to demonstrate the present invention, it should be understood that the present invention can be used with other designs of anchors of the type of pivoting and pivoting and those skilled in the art will This description finds other ways of practicing the invention.
