The disclosure relates to lifting devices and more particularly pertains to a new lifting device for raising a log into a cutting position.
The prior art relates to lifting devices.
An embodiment of the disclosure meets the needs presented above by generally comprising a cylinder, a handle, and a wedge. The handle is coupled to and extends from the cylinder equally distant from opposing ends of the cylinder. The wedge is coupled to and extends from the cylinder proximate to the handle. The wedge is substantially perpendicular to the handle. The wedge is configured to be positioned beneath a felled log, positioning a user to grasp and pull on the handle to rotate the cylinder to apply a lifting force to the log so that the log is supported upon the handle above a surface. The log thus is positioned to be safely cut by the user using a chain saw, or other log cutting implement.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
The cylinder 12 may be hollow so as to reduce the overall mass of the device 10. The opposing ends 18 of the cylinder 12 may be separated by from 40.0 to 80.0 centimeters. The opposing ends 18 are separated by 61.0 centimeters. The handle 14 may have a length of from 100.0 to 200.0 centimeters. The handle 14 has a length of 152.4 centimeters. The handle 14 may be circularly shaped when viewed longitudinally.
The handle 14 comprises a plurality sections 20, as shown in
A set of first fasteners 28 is coupled to the first section 22 distal from the cylinder 12. A set of second fasteners 30 is coupled to the second section 24 so that each second fastener 30 is positioned to couple to a respective first fastener 28 to couple the second section 24 of the handle 14 to the first section 22 of the handle 14. The second fastener 30 may comprise a pin 32 that is spring loaded, as shown in
The wedge 16, the handle 14, and the cylinder 12 comprise metal. The wedge 16, the handle 14, and the cylinder 12 may comprise at least one of steel and aluminum, or other metal, such as, but not limited to, titanium and the like.
The wedge 16 may comprise a set of wedges 16. Each wedge 16 comprises a first segment 36 and a second segment 38. The first segment 36 is shaped complementarily to an orifice 40 that is positioned in the cylinder 12. The orifice 40 is positioned to selectively insert the first segment 36 of a respective wedge 16 to removably couple the respective wedge 16 to the cylinder 12.
Each second segment 38 has a respective length so that the set of wedges 16 comprises wedges 16 that have second segments 38 that comprise a variety of lengths. The set of wedges 16 comprises a first wedge 16, which has a second segment 38 that has a length of 25.4 centimeters, and a second wedge 16, which has a second segment 38 that has a length of 38.1 centimeters. The set of wedges 16 also may comprise additional wedges 16 having additional lengths.
In use, the wedge 16 is positioned beneath a felled log. The user then grasps and pulls on the handle 14 to rotate the cylinder 12 to lift the log so that the log is supported upon the handle 14 above a surface. The log thus is positioned to be safely cut by the user using a chain saw, or other log cutting implement.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the elements is present, unless the context clearly requires that there be only one of the elements.
