Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates generally to a support stake for use in providing support to a structure.

[0003] 2. Related Art

[0004] In the construction industry it is often necessary to insert a stake into the ground to provide support for one structure or another. One such case often arises when forming a concrete slab, curbing or gutter. Since concrete is generally poured in an uncured, liquid state, the wet concrete is poured into an area defined by a form which retains the concrete until the concrete has cured. Forms made of wood or metal which define an area where the concrete is to be placed are often constructed on top of the ground or earth. Typically, the forms are constructed on bare earth by driving a metal support stake into the ground with a sledge hammer. The wooden or metal forms are then secured to the support stake in order to prevent the forms from moving or being deformed when filled by the heavy, wet cement.

[0005] The supports stakes used for this procedure are typically pounded downwardly into the ground. This process can be troublesome in that rocks or other obstructions often exist in the ground that sometimes prevent the support stakes from entering or piercing the ground. Thus, a support stake is often pounded partially into the ground only to have to be removed after an obstruction is contacted. The force ordinarily applied to the top of the support stake often causes the support stake to deform or become bent after use, which limits the useful life of many conventional support stakes. This wear is often exacerbated by the occasions when the support stake contacts an obstruction, which can result in deformation of the support stake even when in a relatively new state.

[0006] Even when support stakes are successfully pounded into the ground without deformation occurring, removal of most support stakes often causes deformation of the stake. For instance, most support stakes are removed by striking the stake on one side and then another to compact the earth around the support stake to increase the size of the hole the stake created when pounded into the ground. By enlarging this hole, the lateral, frictional force imparted by the ground is reduced, and the stake can be more easily pulled from the ground. However, the lateral strike forces applied to the stake increase the time it takes to remove the stake and also necessarily lead to increased deformation or bending of the stake, and thus shorter life of the stake.

[0007] In addition, much time and labor is involved in pounding each stake into the ground prior to pouring cement, then removing each stake from the ground after the concrete has cured. To accomplish the task of constructing long segments of forms, such as are required when long stretches of sidewalk or curbing are poured, a team of four to six workers is often used to install and remove the numerous stakes required in a timely manner. Such an outlay of manpower is both administratively complex and expensive.

SUMMARY OF THE INVENTION

[0008] It has been recognized that it would be advantageous to develop a support stake that is capable of being driven into the ground without requiring the stake be pounded into the ground to install the stake and without requiring that the stake be pounded from side to side to remove the stake.

DETAILED DESCRIPTION

[0034] Reference will now be made to the exemplary embodiments illustrated in the drawings, and specific language will be used herein to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Alterations and further modifications of the inventive features illustrated herein, and additional applications of the principles of the inventions as illustrated herein, which would occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention.

[0035] As illustrated in FIG. 1, a system, indicated generally at 10, in accordance with the present invention is shown for a stake device for providing support to a structure. The stake 12 includes an upper end 14 which includes interface means or engagement section 16 for transferring torsional force to the support stake. The interface means enables an operator to rotate the support stake 12 about a longitudinal axis 18 of the support stake to facilitate threading of the stake into the ground or earth.

[0036] The interface means or engagement section can be configured in a variety of ways. For instance, the engagement section can be an octagon shaped section similar to a head of a conventional bolt. Of course, a hexagon shape can also be used, as can any shape or structure known to those skilled in the art for providing an interface between a stake and a tool, such as a slotted interface similar to a screw and screwdriver arrangement. The present invention can thus be used to rotationally drive a stake into the ground instead of pounding stakes into the ground, as is required with conventional stakes. As one example of a use of the stake, an electric or pneumatic drill or impact wrench can be fitted with a socket and the socket can be placed on a hexagonal head of the support stake. The drill or wrench can then be used to thread the support stake into the ground.

[0037] The stake includes a lower end 20 which can include thread means or threaded section 22 for threadably engaging ground to allow the support stake to be threaded downwardly into the ground. The thread means or threaded section can be of any type known to those skilled in the art, and can be formed below an outer surface of the stake or raised above the outer surface. In one embodiment of the present invention, the threads are formed at 2.5 threads per inch and are approximately {fraction (3/16)}″ to {fraction (5/16)}″ deep. The invention thus provides a support stake that is easy to install and equally easy to remove.

[0038] An elongate intermediate section 24 can be included on the stake and can include at least one opening 26 formed within the intermediate section. The openings 26 can be formed in the intermediate section such that they run substantially orthogonally to the longitudinal axis 18 of the support stake. That is, when the stake is in a substantially vertical orientation, the openings will lie in a substantially horizontal orientation. The openings are configured to receive a securing device (shown at 50 in FIG. 5) to secure the support device to the structure.

[0039] The present invention can be utilized in any operation that can benefit from the presence of a support stake driven into the ground. One such operation is forming curb or sidewalk forms, wherein traditionally four to six workers may be dispatched to install and uninstall the many stakes required to support the forms. Using the present support stake, one or two workers can be equipped with power tools and can install and uninstall the many stakes required in the same amount of time it previously took four to six workers, using conventional stakes and sledgehammers. While much of the present discussion will focus on the support stake as used to provide support to a concrete form, the present invention is not so limited. For instance, the support stake can be advantageously used to form string-line systems, used as survey stakes, or used to support landscape timbers. These applications, as well as many more, can benefit from a support stake that can be quickly and easily threaded into ground and can also be quickly and easily threadably removed from the ground.

[0040] As shown at 24 in FIG. 2, the elongate intermediate section can include a substantially circular cross sectional area. While any cross sectional shape can be used for the intermediate section, a substantially circular cross sectional shape will allow the support stake to be inexpensively formed and provides the further benefit that the outer surface of the stake can be flatly engaged by or against another structure without having to align the stake in any particular rotational alignment. The openings 26 can each comprise a channel formed in the intermediate section 24 and can be spaced along the longitudinal axis 18 of the stake 12. As shown by L in FIG. 1, a total length of the device can be at least 12 inches long, long enough to firmly engage the ground and yet still provide an area in which securing devices or fasteners are secured to the stake. In one embodiment, the total length of the stake is between 12 inches and 48 inches, with the threaded section being 8 inches to 10 inches in length.

[0041] As shown in perspective view in FIG. 1 and in detail in FIG. 4, each channel can also be oriented at an angle A from an immediately adjacent channel. For instance, the channels 26c and 26d are formed at angle A relative to each other. By spacing the openings along the longitudinal axis 18 of the stake, and by forming the openings at alternating angle A, a series of openings can be easily aligned with a structure to which the stake is to be secured. For instance, the angle can be selected from the group consisting of 15°, 30°, 45°, 60°, 75° and 90°. Thus, if multiple openings are aligned at 30° from each other, when an operator is rotationally driving the stake into the ground, he or she need rotate the stake only 30° one direction or another in order to align a set of openings such that a securing device can be driven through an opening and into the structure.

[0042] This concept is illustrated by the embodiment shown in FIG. 5. Here, the securing device 50, which can be a nail, for example, is oriented through the stake 12 in one of openings 26f into a structure 52. The series of openings 26e are shown as aligned parallel to the structure 52, whereas the series of openings 26f are formed at a perpendicular angle to the alignment of the structure. Thus, in the embodiment shown, the openings 26e and 26f are formed at an angle of 90°. Consequently, an operator, while rotationally driving the stake 12 into the ground 54, would rotate the stake 90° one way or the other to align one set of openings with the structure to enable securing devices to be driven through the stake and into the structure.

[0043] The openings 26 in the stake 12 are not limited to channels or holes formed in the stake. For instance, the opening can comprise alternate shapes such as rectangular notches, and can be formed internally or on an outside of the stake. Alternate embodiments of the openings are shown in FIGS. 3a and 3b, at 26a and 26b, respectively. The opening 26a in FIG. 3a is a groove formed around an outer circumference of the stake. The opening 26a can thus be engaged by a U-shaped nail or other fastener as the fastener is driven into a support structure. This type of opening is advantageous in that the stake 12 need not be precisely aligned in any rotational orientation in order for the fastener to engage the opening in the stake.

[0044] The opening 26b shown in FIG. 3b is a loop formed in a ring that can rotationally engage the stake 12. This type of opening is similarly advantageous in that the stake 12 need not be precisely aligned in any orientation, but can be engaged by a fastener in any rotational orientation. Thus, once the stake 12 is rotationally driven into the ground, the opening 26b can be turned around the stake until properly aligned, and a fastener can be driven through the opening and into a structure.

[0045] The present invention also provides a method of securing a concrete form for receiving uncured concrete, illustrated in FIG. 5. Here, a support stake 12 can be placed on ground 54 adjacent a location of the form 52. The support stake can then be threadably engaged into the ground by applying a torsional force to the support stake at interface means or engagement section 16. Once engaged into the ground, the support stake can be secured to the concrete form 52 by securing a fastener 50 to the support stake and the form. The fastener or securing device can be any known to those skilled in the art, such as a nail, screw or bolt, and can either be in a straight configuration, a U-shaped configuration, or any shape known to those in the art. Once the form and stake are in place, uncured concrete 56 can then be placed on the opposing side of the form 52, and the form 52 will be held in place by the stake 12.

[0046] The support stake 12 can be rotationally driven into the ground by using a power tool 58 to apply the torsional force to the stake. Such power tools may, for instance, be a pneumatic wrench, an electric wrench, a pneumatic drill, or an electric drill, as are known to those skilled in the art. Of course, a hand driven tool such as a socket attached to a ratchet may also be used. Thus, to install the support stake into the ground, a user can simply place the stake in a desired location, engage the support stake with a tool, and quickly drive the support stake into the ground. Should an obstacle in the ground be encountered, the stake can be quickly rotated out of the ground, moved to a new location, and driven into the ground again. After the concrete has at least partially cured, the fastener 50 can be removed from the stake and form, and the stake can be threadably removed by applying a torsional force in an opposite rotational direction as that used to engage the support stake into the ground.

[0047] The present invention thus provides a support stake that can be easily driven and removed form ground or earth. If an obstacle is encountered while driving the stake into the ground, an operator can quickly and easily reverse direction of the tool used to install the stake, quickly remove the stake, move it to a new location, and reinstall the stake. The threaded section of the stake can allow an operator to accurately and easily adjust the depth of insertion into ground, and thus the height the stake protrudes above the ground. In addition to providing a support stake that is faster and simpler to install, the present invention can substantially increase the life of the support stake, as the support stake will not become deformed or bent, as previous stakes were due to pounding the stakes into and out of the ground.

[0048] It is to be understood that the above-referenced arrangements are illustrative of the application for the principles of the present invention. Numerous modifications and alternative arrangements can be devised without departing from the spirit and scope of the present invention while the present invention has been shown in the drawings and described above in connection with the exemplary embodiments(s) of the invention. It will be apparent to those of ordinary skill in the art that numerous modifications can be made without departing from the principles and concepts of the invention as set forth in the claims.
