1. Field of the Invention
The present invention relates generally to a post pulling attachment and more specifically it relates to a post pulling attachment system which easily attaches and detaches from a bucket to aid in safely and efficiently removing a post from the ground.
2. Description of the Related Art
Any discussion of the related art throughout the specification should in no way be considered as an admission that such related art is widely known or forms part of common general knowledge in the field.
Posts are often used in constructing fences and the like. Due to the posts' effect on the structural integrity of a supported system (such as a fence), it is extremely important that such installed posts be firmly and securely anchored in the ground. Typically, posts are buried within the ground such that at least a third of the length is below-grade for support of the above-grade post. Further, a cement footing is generally poured around the base of the post to further secure the post in the ground.
While such methods have been successfully utilized to secure a post firmly in the ground, such posts are often required to be removed for replacement or other reasons. The methodology utilized to secure the post firmly in the ground also has the side-effect of making removal of the post exceedingly difficult.
In the past, such posts have had to be manually dug out or, in some cases, ripped out from the ground using a chain secured to a vehicle such as a skid steer loader. While using such a method has proven effective, the risks of injury related to usage of a chain, which can often break or move erratically after removal, is extremely high.
Because of the inherent problems with the related art, there is a need for a new and improved post pulling attachment system which easily attaches and detaches from a bucket to aid in safely and efficiently removing a post from the ground.
The invention generally relates to a post pulling attachment which includes an outer securing plate and an inner securing plate which are positioned on either side of a bucket. Each of the securing plates includes a plurality of corresponding apertures through which a pair of removal members are extended both to secure the present invention to the bucket and to aid in removing a post. When installed, the removal members will extend outwardly from the bucket in spaced-apart relationship. By positioning a post between the removal members, rotating the bucket to jam the post therein and then lifting the bucket, a post may safely and efficiently be removed from the ground without use of a chain. There has thus been outlined, rather broadly, some of the features of the invention in order that the detailed description thereof may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and that will form the subject matter of the claims appended hereto. In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction or to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of the description and should not be regarded as limiting.
Various other objects, features and attendant advantages of the present invention will become fully appreciated as the same becomes better understood when considered in conjunction with the accompanying drawings, in which like reference characters designate the same or similar parts throughout the several views, and wherein:
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views,
The present invention is adapted primarily for use in combination with a bucket 12 as is commonly present on skid steer loaders and other working vehicles. While the figures illustrate an exemplary embodiment secured to such a bucket 12, it is appreciated that the present invention and its principles may be applied to a wide range of structures. Thus, the scope of the present invention should not be construed as being limited to applications involving the usage of buckets 12. The securing plates 20, 30 may be secured to a number of structures.
As best shown in
The pair of securing plates 20, 30 is generally comprised of an outer securing plate 20 which is secured against an outer surface of the bucket sidewall 13 and an inner securing plate 30 which is secured against an inner surface of the bucket sidewall 13. As shown in
The securing plates 20, 30 are each preferably comprised of substantially flat, rectangular members, each having an upper end 21, 31 and a lower end 22, 32. However, it is appreciated that various other shapes may be utilized, and the present invention should not be construed as being limited to rectangular securing plates 20, 30.
Both securing plates 20, 30 generally include a plurality of apertures 24, 34 through which the removal members 40, 50 of the present invention will extend both to secure the present invention to the bucket 12 as well as to assist in the removal of posts 15. As shown in
In an alternate embodiment as shown in
As best shown in
Generally, a first removal member 40 will extend through both the first and second securing plates 20, 30 through a first aperture 24, 34 on each and a second removal member 50 will extend through both of the plates 20, 30 through a second aperture 24, 34 on each as shown in
The first removal member 40 preferably includes a bolt head at its first end 41 and a threaded portion adjacent its second end 43. Similarly, the second removal member 50 preferably includes a bolt head at its first end 51 and a threaded portion adjacent its second end 53. Preferably, the first removal member 40 will mirror the structure of the second removal member 50.
Similarly, the second removal member 50 is extended through a corresponding aperture 24, 34 on each of the plates 20, 30. The apertures 24, 34 utilized for the second removal member 50 will be different from those which are utilized for the first removal member 40 to ensure that the removal members 40, 50 are horizontally offset. A first nut 54 is tightened around the threaded portion 53 of the second removal member 50 adjacent the outer securing plate 20 and a second nut 55 is tightened around the threaded portion 53 of the second removal member 50 adjacent the inner securing plate 30 as shown in
In some embodiments, a sheath 47, 57 may be provided for one or both of the removal members 40, 50. The sheaths 47, 57 are comprised of hollow, elongated members which cover the exposed portion of the removal members 40, 50 as shown in
With the present invention installed on the bucket 12, the bucket 12 is then lowered such that a post 15 is positioned between the removal members 40, 50 as shown in
Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although methods and materials similar to or equivalent to those described herein can be used in the practice or testing of the present invention, suitable methods and materials are described above.
