Description

BACKGROUND

Agricultural crop fields have long been used for grazing cattle and other livestock during portions of the year. Typically after harvest, grain or seed loss from corn or soybeans may be left behind by combines or other harvesting equipment that cannot recover 100% of the available crop. This is often the case in fields used for corn and soybeans.

To avoid waste of such crops, cattle or other livestock may be introduced to the fields for a period of time after harvest. The animals consume the crop left in the field and, in the case of corn and some other crops, stover as well. This reduces waste and increases total economic output from the fields.

However, such fields may not always be fenced with fences suitable to restrain the livestock. Further, when fencing is present, it is typically positioned around the utmost perimeter of a property and may include stationary equipment, culverts, creeks, dwellings, storage structures, or other areas access to which should be restricted for the livestock to avoid damage to the structures and areas or injury to the animals. A fairly common solution to this problem is to temporarily install supplemental fencing.

Typical fencing for such uses, such as single and double wire electric fences, include fenceposts for supporting wires or other fencing materials. These posts are typically of a relatively small diameter to facilitate their placement into the ground. When placed after harvest, the posts may be able to be relatively easily driven into the ground. In some situations, hammers, post drivers, or other device may be used.

Another issue with the use of such fences is that they must be removed after the livestock is removed and before the field is planted for the following season. However, the ground may be particularly hard, dry, or frozen at this time as it is before spring planting. The result is that it may be very difficult for an individual to remove the posts from the ground.

Accordingly, there is a need for a tool to facilitate removal of fenceposts from the ground. Additionally, in cases where removal is particularly difficult, there is a need for an assisting device that can further assist in the removal of the posts from the ground. Further, there is a need for a kit including both a tool and assisting device that may be utilized as needed by a user for removal of fenceposts from the ground.

DETAILED DESCRIPTION

A fencepost tool 10 may generally include a first arm 12 and a second arm 14. Each of the first and second arms 12 and 14 may include a handle 16 and 18, respectively, and working portions 20 and 22, respectively. Each of working portions 20 and 22 may include a top surface 24 and 26, respectively, a bottom surface, 28 and 30, a front surface 32 and 34, respectively, and a back surface 36 and 38, respectively. Working portions 20 and 22 are shown as generally elongated structures positioned relative to each other such that they align along a common axis and coupled to the respective handle with which they form an arm at ends distal to one another.

First arm 12 and second arm 14 may be coupled by links 40 and 42. Links 40 and 42 are shown as coupled at axes of rotation about which working portions 20 and 22 may pivot. The axes of rotation are generally parallel to each other and extend from the front surfaces 32 and 34 through back surfaces 36 and 38, respectively. Links 40 and 42 are generally shown as oval plates with openings configured to align with apertures through working portions 20 and 22 in-line with the axes of rotation. Fasteners 44 and 46 may be utilized to couple first arm 12 and second arm 14. Fasteners 44 and 46 are shown as clevis pins passing through link 40, one of working portions 20 or 22 and through link 42. Fasteners 44 and 46 may be retained by locking elements such as cotter pins.

Working portions 20 and 22 include faces 52 and 54 which oppose each other and on each arm 12 and 14 and are positioned distal to the positions at which working portions 20 and 22 are coupled to handles 16 and 18, respectively. One or both of working portions include a recess along an edge where such working portions face meats such working portions bottom surface. The recesses 56 and 58 are shown with both of working portions 20 and 22, respectively, and extend from front surface 32 or 34 to back surface 36 or 38. Recesses 56 and 58 prevent interference from material preventing movement of first arm 12 and second arm 14 relative to each other whereby fencepost tool 10 may be transitioned from an open position to a closed position and vice versa.

Working portions 20 and 22 further include engagement surfaces 60 and 62. When fencepost tool 10 is in a closed position, engagement surfaces may form an opening through which a fencepost may be received. The opening may be sized such that it is slightly smaller than the cross-sectional dimensions of the fencepost. Such a configuration allows fencepost tool 10 to be positioned over a top of the fencepost with the fencepost tool 10 in the open position and moved downwardly. At a desired height above the base of the fencepost, fencepost tool 10 may be transitioned to a closed, or nearly closed, position such that the engagement surfaces 60 and 62 come into contact with an exterior surface of the fencepost.

In use, a user may transition fencepost tool 10 to the closed, or nearly closed, position by moving the handles 16 and 18 upwardly to a point at which engagement surfaces 60 and 62 contact the fencepost. At this point, the fencepost will interfere with further closing of fencepost tool 10 and further force directed upwardly on handles 16 and 18 will be transferred to the post and effect removal of the fencepost from the ground.

In some situations, such as when the fencepost to be removed is in particularly hard, dry, or frozen ground, it may be advantageous to facilitate application of greater upward force to fencepost tool 10 when it is closed on a fencepost to be removed. Assisting device 110 may be used in conjunction with fence tool 10 in such situations. Assisting device 110 includes a bearing portion 112 shown as plate. While shown as circular, bearing portion 112 may be of any suitable geometry including, but not limited to square, rectangular, or polygonal. A tensile member 114 may be provided and is shown as chain. Tensile member 114 is coupled to bearing portion 112 at opposing sides of bearing portion 112. Alternatively, multiple tensile members may be used, or configured to be coupled to bearing portion 112 at more than two positions. Bearing portion 112 includes an aperture 116 which is configured to receive a fencepost.

When used, assisting device 110 may be passed over the top of the fencepost and lowered towards the ground or even dropped to the ground with the fencepost passing through aperture 116. Fencepost tool 10 is then positioned over a top of the fencepost with the fencepost tool 10 in the open position and moved downwardly. At a desired height above the base of the fencepost, fencepost tool 10 may be transitioned to a closed, or nearly closed, position such that the engagement surfaces 60 and 62 come into contact with an exterior surface of the fencepost. Alternatively, fencepost tool 10 may be lowered proximate to the level of bearing portion 112, transitioned to a nearly open position, and rested on a top surface 118 of bearing portion 112.

In some embodiments, a flexible material such as an elastomer may be provided. Such material may be positioned in the opening to provide an engagement surface and allow a single tool to be utilized with posts of various sizes. Additionally, the working portions may be adjustable by screws coupled to the face surfaces allowing the size of the opening to be adjusted.

A mechanized lift, such as a backhoe, forklift, or similar machine may engage tensile member 114 by putting a tine of the forklift, backhoe or other device through the loop defined by bearing portion 112 and tensile member 114. When the mechanized lift is raised, slack in tensile member 114 (if any) may be taken up. The tension then exerted through tensile member 114 translates to an upward force on bearing portion 112 and, thereby, to the bottom surfaces 28 and 30 of working portions 20 and 22. This biases fencepost tool 10 into a closed, or nearly closed position such that engagement surfaces 60 and 62 contact the outer surface of the fencepost and translate the upward force to the fencepost and thus remove it from the ground. In other embodiments where a mechanized lift is not available or otherwise practical, a pulley system or other device for creating mechanical advantage may be utilized with assisting device 110 to facilitate removal of a fencepost from hard, dry, or frozen ground.

While specifically applicable to the removal of fenceposts from the ground, fencepost tool 10 may be used independently, or in conjunction with assisting device 110 to remove other devices from the ground. Similarly, rebar or other tensile components may be engaged to apply a tensile force while prefabricating concrete structures. Similarly, other applications can be envisioned where the mechanical advantage made possible through use of the tool, with or without the assisting device, may be used to apply a force to an object in an upward or other direction to facilitate removal, displacement, or achieve some other objective.

In some embodiments, a kit may be provided having both a fencepost tool 10 and an assisting device 110.
