The presently disclosed subject matter relates to a tool for removing sunken post from a sub surface position.
Posts are driven into the ground for purposes of establishing a fence for containment, or as part of a structure, or other general construction project. Sometimes the posts are permanent in nature, meant to stay in place long term. Other times, the posts are temporary in nature, installed into the subsurface, but needing removal at some later date. In these instances, the posts are driven into the ground, often at a depth of two (2) or more feet. The ground may be soft and more pliable when installed, however, after time, the posts become very challenging to remove from the ground for temporary installation.
With metal “t-posts” that are installed in the ground, removal is most often accomplished by wrapping a chain around the t-post and using a lift or pole attached to hydraulic powered equipment to remove the post from the ground. This process has many significant advantages. Wrapping the chain around the post is cumbersome, requiring an extra person to wrap the chain and one to operate the equipment. Additionally, the post is often bent when being pulled up out of the ground, as the uneven forces from the chain impart a bending force onto the post. Finally, the post will often suddenly break suction with the soil and projectile out of the ground surface, creating a dangerous situation where persons could be injured.
Accordingly, it would be beneficial to provide an improvement that addresses the above-noted disadvantages.
This summary is provided to introduce in a simplified form concepts that are further described in the following detailed descriptions. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it to be construed as limiting the scope of the claimed subject matter.
Disclosed herein is a tool for use in removing a post from the ground. The tool includes a housing having a recess therein for slidably receiving the post, and a hinged support arm extending from the housing into the recess. The support arm is initially angled relative to the recess such that a protrusion extending from the post received within the recess causes a ramp-up movement relative to the support arm when the tool is being lowered onto the post as the protrusion impacts the support arm, and a locked-in-place orientation when the support arm is wedged onto a lower surface of the protrusion as the tool is being translated upwardly. The hinged support arm is biased into the locked-in-place orientation.
According to one or more embodiments, the recess in the housing has a main channel for receiving a back portion of the post, and a planar section defining the channel for receiving another portion of the post.
According to one or more embodiments, the hinged support arm is biased into the locked-in-place orientation by a spring extending from a tab off the hinged support arm to the housing.
According to one or more embodiments, pressing of the tab imparts hinged movement of the hinged support arm.
According to one or more embodiments, the hinged support arm is biased into the locked-in-place orientation by a spring.
According to one or more embodiments, the housing defines an opening for receiving a chain or other fastener to couple the tool to an equipment for imparting the upward translation.
According to one or more embodiments, the hinged support arm extends between two opposing panels that protrude from the housing.
According to one or more embodiments, the hinged support arm is carried by a pin or fastener extending between the two opposing panels.
According to one or more embodiments, the post being worked on by the tool is a t-post.
According to one or more embodiments, the housing defines a vertically extending support to which a chain or other fastener couples the tool to an equipment for imparting the upward translation.
Below, the technical solutions in the examples of the present invention are depicted clearly and comprehensively with reference to the figures according to the examples of the present invention. Obviously, the examples depicted here are merely some examples, but not all examples of the present invention. In general, the components in the examples of the present invention depicted and shown in the figures herein can be arranged and designed according to different configurations. Thus, detailed description of the examples of the present invention provided in the figures below are not intended to limit the scope of the present invention as claimed, but merely represent selected examples of the present invention. On the basis of the examples of the present invention, all of other examples that could be obtained by a person skilled in the art without using inventive efforts will fall within the scope of protection of the present invention.
A tool for use in removing a post from the ground is generally designated 10 and the post designated 1, a protrusion from the post designated 2, and a ground surface designated 3. The tool 10 includes a housing 12. The housing 12 is shown constructed out of metal, which may be a usual embodiment, however, the housing 12 may be constructed out of any material and may take on many various types of construction and dimensionality. The housing 12 may define a recess 14 therein for slidably receiving the post 1. The recess 14 and associated features will be described in more detail later.
A hinged support arm 16 extends from the housing 12 into the recess 14. The hinged support 16 may take on any appropriate construction and dimensionality, and may embody a flat blade shape as shown, or may embodiment more of a rod or similar shape. As will be described in more detail later, the support arm 16 may be initially angled relative to the recess 14 such that the protrusion 2 extending from the post 1, where the post 1 is received within the recess 14 causes a “ramp-up” movement of an end of the support arm 16 when the tool 10 is being lowered onto the post 1 as the protrusion 2 impacts the end of the support arm 16. The support arm 16 also a locked-in-place orientation when the support arm is wedged onto a lower surface of the protrusion as the tool is being translated upwardly. In one or more embodiments and as will be described with greater detail herein, the hinged support arm 16 is biased into the locked-in-place orientation.

Operation of the tool is illustrated in
The tool 10 is shown working on a t post 1, but can be used with a variety of structures where the end of support arm 16 “digs into” the structure upon being translated upwardly. For example, the tool 10 can have a larger recess area 14 that accommodates wooden stakes or posts, or more in some embodiments work on a ridged rebar structure. For further reinforcement, an additional chain structure can extend from the tool 10 to further wrap around any t post or similar that is exceedingly sunk into the ground.
