Abstract

An anchor to secure a cord or other tying device to the ground includes a stake which is driven into the ground. At its leading end the stake has hinge plates which are movable relative to the stake about hinge pins. As the stake is driven into the ground, the hinge plates lie along the side of the stake, projecting toward the trailing drive end thereof. Once inserted, the stake is withdrawn slightly, and this causes the hinge plates to swing outwardly to an anchoring position wherein they project laterally from the stake and secure the stake firmly in the ground. A retaining cord is provided for holding plates in the anchoring position. To remove the anchor from the ground, the retaining cord is released, permitting the hinge plates to fold against the stake in the opposite direction as the stake is withdrawn. The cord which is secured by the anchor is attached to the stake between its leading end and its longitudinal midpoint.

BACKGROUND OF THE INVENTION This invention relates in general to an anchoring device and, more particularly, to a device for anchoring a flexible tying device such as a cord.

The typical ground anchor for securing a cord to the ground on a temporary basis is merely a stake which is driven into the ground and has the cord tied around its upper end, which usually projects above the ground. This arrangement creates tremendous leverage on the stake, and in many instances causes the top of the stake to pull over and loosen the securement.

SUMMARY OR THE INVENTION One of the principal objects of the present invention is to provide an anchor for firmly securing a cord to the ground. Another object is to provide an anchor of the type stated which is light in weight, easy to carry and store, and simple to operate. A further object is to provide an anchor of the type stated which has tremendous holding power. An additional object is to provide an anchor which is ideally suited for securing small boats, tent ropes, and beach equipment. Still another object is to provide an anchor of the type stated which is easily removed from the ground so that it may be reused. These and other objects and advantages will become apparent hereinafter.

The present invention is embodied in an anchor device including a stake and at leastone hinge plate on the stake. The hingeplate moves about a hinge axis between insertion, withdrawal and anchoring positions. In the insertion and withdrawal positions the hinge plate extends in the direction of the stake and may be easily inserted and withdrawn, respectively, from the ground. In the anchoring position the hinge plate extends latually from the stake. The invention also consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

DETAILED CONSTRUCTION AND DESCRIPTION In FIG. 1, reference numeral 11 represents a complete hinge which includes an intermediate plate 12a leftside hinge plate 13 and a rightside hinge plate 14 which are interconnected together by means of transverse extending pins 15. An opening 16 in each left and

right plates

13 and 14 serve to receive the cords 31, 30. On the intermediate plate 12 there are two pairs of openings 17 that serve as bolt holes. The reference nu- I meral 18 represents a coil spring placed on a main stake 25 to push out the left and

right plates

13 and 14, the spring 18 being fitted through the stake 25. The spring 18 thus aids in spreading the hinge. A ring 19 serves to be tied on the end of the anchor cord 34.

A metal plate 20 shown in FIG. 2 has a key hole 21 for receiving a hook or pin 22 shown in FIG. 1. Screw openings 23 are provided upon the metal plate 20. Additionally there is provided an eye screw 24 through which the anchor cord 28 is fitted and guided.

As shown in FIGS. 3 to 6, there is a main stake 25 to opposite sides 26 of which flat blocks 27-are secured in alignment with the upper edge of the main stake. The block 27 is approximately one-half inch thick and one and one-half inches in length. The plate 20 with the key hole 21 is secured to one of the blocks 27 as shown.

A cord 28 is attached to one end to the pin 22, the cord 28 being extended through the eye screw 24 and the opposite end of the cord 28 being connected by means of a knot 29 to two separate cords 30 and 31. The cord 30 at its opposite end is connected to the opening 16 in the right hinge plate 14 while the other cord 31 extends through a diagonally extending hole 32 through the main stake and the opposite end of the cord 31 extending out of the hole 32 is connected to the opening 16 in the left hinge plate 13. The

cords

28, 30 and 31 and the hook 22 constitute retaining means for holding the

plates

13 and 14 in a laterally extending anchoring position. A transverse extending opening 33 through a lower portion of the main stake 25 is adapted to receive a spring 18 which in a relaxed position extends out of each opposite side of the main stake as shown in FIG. 4 of the drawing. An anchor cord 34 is connected at one end to a lower portion of side edge 35 of the main stake 25, the opposite end of the anchor cord 34 being connected to the ring 19.

As shown in the comparative positions illustrated in FIGS. 4, 5 and 6, it is now evident that when the hinge left and right plates are pivoted in an upwardly position as shown in FIG. 5, the spring 18 is in a compressed position within the interior of the transverse opening 33 that extends through the main stake. When the pin 22 is unhooked from the block 27, as shown in FIG. 6, the left and

right hinge plates

13 and 14 are downwardly pivoted.

It is to be noted that one of the side blocks 27 on one side of the main stake comprises a member 20 which includes the key hole 21 for allowing the pin 22 to be hooked therewithin. The opposite block 27 is plain such as is shown in FIG. 7.

It is to-be additionally noted that the present invention includes a bolt and nut set 36 which are shown in an operative position in FIG. 9.
