The disclosure and prior art relates to post hole diggers and more particularly pertains to a new post hole digger for efficient, assisted hole digging.
An embodiment of the disclosure meets the needs presented above by generally comprising a base plate having a top side separated from a bottom side forming an inner cavity. A pair of jaws is coupled to the base plate. Each of the pair of jaws has a hinge coupled within a proximal end and a distal end extending away from the bottom side of the base plate. The hinge is coupled to the base plate to allow the jaw to pivot such that the pair of jaws has an open position and an alternate closed position in which the distal ends of each jaw touch. The pair of jaws is configured to secure hard soil, clay, rocks, concrete, or a post base. A bottom end of each of a pair of handles is coupled to the proximal end of the pair of jaws. The pair of handles is used to move the pair of jaws between the open position and the closed position with greater leverage. A hole saw is coupled to the base plate and comprises a motor, a battery pack, a piston coupled to the motor and extending through the bottom side, and a bit head that is selectively engageable with the piston. The piston is driven by the motor and the bit head is configured to break up hard soil, clay, concrete, rocks, or a post base. The curvature of the pair of jaws prevents contact with the hole saw in the open position, the closed position, and all intermediate positions therebetween. A plurality of controls is coupled to the pair of handles and is in operational communication with the hole saw.
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
A hole saw 34 is coupled to the base plate 12. The hole saw 34 comprises a motor 36 coupled within the inner cavity 18, a battery pack 38 coupled to the top side 14, a piston 39 coupled to the motor 36 and extending through the bottom side 16, and a bit head 40 having a toothed perimeter 43 and being selectively engageable with the piston 38. The piston 38 is driven by the motor 36 and the bit head 40 is configured to break up hard soil, clay, concrete, rocks, the post base, or other aggregate to then be secured and removed by the pair of jaws 20. The piston 39 may be threaded such that the motor 36 can lower and alternatively raise the piston 39 relative the base plate 12. The bit head 40 may be replaceable or interchangeable to allow for different sizes or purposes depending on the material being dug out. The base plate 12 may be cylindrical to minimize the footprint while the curvature of the pair of jaws 20 prevents contact with the hole saw 34 in the open position, the closed position, and all intermediate positions therebetween.
A pair of lights 41 is coupled to the pair of handles 30. Each of the pair of lights 40 comprises a ring 42, a light housing 44, and a bulb 46. The ring 42 is coupled around the handle 30 proximal the bottom end 32 and the light housing 44 extends from the ring 42. The light housing 44 may be rectangular prismatic with the bulb 46 being coupled within an underside 48 of the light housing to illuminate the pair of jaws 20 and the surrounding area. The pair of lights 41 is in operational communication with the battery pack 38.
A plurality of controls 50 is coupled to the pair of handles 30. The plurality of controls 30 may comprise a pair of rectangular control housings 52 coupled to an outer side 54 of each of the pair of handles proximal a top end 56 to allow operation while gripping the pair of handles 30 for use. The plurality of controls 50 is in operational communication with the hole saw 34 and the pair of lights 40 to rotate the bit head 40 in either direction, to raise and alternatively lower the piston 39, and to operate the pair of lights 41.
In use, the pair of jaws 20 is inserted into the ground and the plurality of controls 50 is used to operate the motor 36 to lower the piston 39 and spin the bit head 40 to break up the material, then to raise the piston 39 and disengage the motor 36. The pair of handles 30 is then squeezed together and lifted to remove material. This process is then repeated until a hole is dug to the desired depth.
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 element is present, unless the context clearly requires that there be only one of the elements.
