Abstract
Description
- This application claims the benefit under 35 U.S.C. §119(e) of U.S. Provisional Patent Application No. 61/498,749, filed Jun. 20, 2011, and entitled POWERED AND MANUAL AUGER, which is hereby incorporated by reference herein in its entirety.
- The present disclosure relates to augers for drilling holes, and in particular to a hole drilling method and apparatus.
- Augers are used to drill narrow holes, such as through ice for ice fishing or in the earth for setting posts. A typical auger has one or more boring blades at the lower end of an upright drive shank and a spiral flighting extending from the boring blades up a lower portion of the drive shank. The drive shank is rotated to turn the blades to bore a hole, such as through the ice. Some augers are manual, such that the drive shank is rotated manually, by an operator turning a crank. Other augers are powered, such that the drive shank is rotated by an electric motor or fuel-powered engine.
- Presently, powered augers cannot be operated by hand, which creates challenges when the source of power (e.g. fuel, electricity, battery, etc.) runs out or is not available. Similarly, present manual augers do not provide a powered option. Accordingly, users desiring a powered auger option may need to carry both a powered auger and a manual auger. Augers can be large and awkward to transport, which makes carrying and transporting two separate augers burdensome.
- The present disclosure is directed to embodiments of and methods of using a hybrid, powered and manual, auger that can be operated as a manual auger or a powered auger independently and in combination.
- Additional aspects and advantages will be apparent from the following detailed description of preferred embodiments, which proceeds with reference to the accompanying drawings.
- The written disclosure herein describes illustrative embodiments that are non-limiting and non-exhaustive. Reference is made to certain of such illustrative embodiments that are depicted in the figures, in which:
-
FIG. 1 is a side view of an electric and manual ice auger, according to one embodiment of the present disclosure. -
FIG. 2 is an enlarged view of a handle portion of the electric and manual ice auger ofFIG. 1 . -
FIG. 3 is an enlarged view of a top handle of the electric and manual ice auger ofFIG. 1 . -
FIG. 4 is an enlarged view of a drive motor of the electric and manual ice auger ofFIG. 1 . -
FIG. 5 is an enlarged view of a battery mount of the drive motor ofFIG. 4 . - The present disclosure is directed to embodiments of and methods of using a hybrid powered and manual auger that can be operated as a manual auger or a powered auger independently and in combination. Described differently, the embodiments of the present disclosure can be operated as a manual auger without power (manual-only operation), or operated as a powered auger driven by a motor without any manual power (power-only operation), or operated as a combined manual and powered auger. A user can rely on a single auger apparatus of the present disclosure to provide a powered auger option, without concern for situations when the power source for the powered auger option runs out or is unavailable. Were the power source to be unavailable, manual-only operation of the auger would be available. Moreover, the user can enhance the drilling capability of the auger by combining manual power and electrical power.
- The following description is made with particular reference to ice augers. However, an ordinarily skilled artisan appreciate that augers can also be used to drill holes for a variety of purposes besides drilling holes in or through ice. For example, an auger can be used to drill holes in the ground, such as for setting posts (e.g. a fence post), or other situations where a narrow hole is advantageous. A typical auger hole is four to ten inches in diameter.
- Embodiments of the present disclosure may be best understood by reference to the drawings, wherein like parts are designated by like numerals throughout. It will be readily understood that the components of the present disclosure, as generally described and illustrated in the drawings herein, could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments of the apparatus is not intended to limit the scope of the disclosure, but is merely representative of possible embodiments of the disclosure. In addition, the steps of a method do not necessarily need to be executed in any specific order, or even sequentially, nor need the steps be executed only once, unless otherwise specified. In some cases, well-known structures, materials, or operations are not shown or described in detail.
-
FIG. 1 is a perspective view of one embodiment of an electric andmanual ice auger 100, according to one embodiment of the present disclosure. Theauger 100 includes abit 102, adrive shaft 104, adrive motor 106, and ahandle portion 108, which includes amanual crank 110. Thebit 102 anddrive shaft 104 are concentric and coaxial, sharing a longitudinal axis that can be referred to as adrive axis 105, about which rotation of various components of theauger 100 occurs and along which the drilling direction occurs, as will be described below. As can be appreciated, other embodiment of an auger can be used for purposes other than drilling holes in ice, such as drilling holes in the ground. - The
bit 102 comprises acentral bit shank 112 to drive one or moreice cutting blades 114 positioned and fixedly secured at the distal (lower) end of thebit shank 112. Aspiral auger 116 or flighting is coaxially mounted around thebit shank 112, extending up thedrive axis 105. Thebit 102, and correspondingly thebit shank 112, theice cutting blades 114, and thespiral auger 116, are configured to rotate around thedrive axis 105, when theauger 100 is in operation. The proximal (upper) end of thebit shank 112 is configured to couple concentrically to thedrive shaft 104 aligned with thedrive axis 105. As thebit shank 112 is rotated about thedrive axis 105, theice cutting blades 114 andspiral auger 116 also rotate around thedrive axis 105. If theice cutting blades 114 are pressed against ice and rotated, theice cutting blades 114 will gradually bore a hole in the ice in a direction distally along thedrive axis 105. Thespiral auger 116 is configured to lift ice shavings away from theice cutting blades 114, proximally along the drive axis, and out of the hole being cut. - As can be appreciated, in another embodiment, the
bit shank 112 and thedrive shaft 104 may be integrated and/or comprise the same component. In the present embodiment, thebit 102 can be removed from thedrive shaft 104 for easy replacement, repair, sharpening, etc. However, this is feature is optional and theblades 114 andspiral auger 116 can be mounted to a single, unitary shaft extending from thedrive motor 106. -
FIG. 2 is an enlarged side view of thehandle portion 108 of the electric and manual ice auger ofFIG. 1 . Thehandle portion 108 comprises atop handle 118 and themanual crank 110. Thehandle portion 108 is configured to allow a user to operate theauger 100 manually. - The
manual crank 110 comprises a U-shaped offset formed by two crank arms, anupper crank arm 120 and alower crank arm 122, joined by acrank handle portion 124. Thecrank arms drive axis 105, at disparate points along thedrive axis 105. Theupper crank arm 120 couples at an inner end to thetop handle 118 and couples at an outer end to thecrank handle portion 124. Thelower crank arm 122 couples at an inner end to thedrive motor 106 or other component coupled to thedrive shaft 104 and couples at an outer end to thecrank handle portion 124. Thecrank handle portion 124 may comprise a tubular member connecting outer ends of thecrank arms drive axis 105. Themanual crank 110 may be operated by rotating thecrank handle portion 124 about thedrive axis 105, thereby rotating thedrive shaft 104 andbit shank 112, which in turn rotates the one or moreice cutting blades 114 and thespiral auger 116. The distance D1 created by thecrank arms crank handle portion 124 and thedrive axis 105 provides leverage to enable themanual crank 110 to drive (rotate) thedrive shaft 104, and in turn rotate thebit 102. - The
crank handle portion 124 may further comprise ahand grip 126 configured to rotate (or spin) about the longitudinal axis of thecrank handle portion 124, allowing a user to more easily rotate thecrank 110 about thedrive axis 105. Therotatable hand grip 126 allows the user to firmly grasp the crank and/or apply a firm downward pressure while turning thecrank 110. - The crank
handle portion 124 may further comprise atrigger 127 to activate thedrive motor 106. Thetrigger 127 may be positioned on thehand grip 126 to allow a user to easily activate the drive motor while grasping thehand grip 126. Thedrive motor 106, when activated by thetrigger 127, may spin thedrive shaft 104 and thebit 102. The trigger of thehand grip 126 of thecrank 110 may work in conjunction with anothertrigger 130, such as on thetop handle 118, to provide a two-button activation safety mechanism, as discussed in greater detail below. -
FIG. 3 is an enlarged view of atop handle 118 of the electric and manual ice auger ofFIG. 1 . Thetop handle 118 comprises an upper shaft that is aligned coaxial with both thedrive shaft 104 and thebit shank 112. Thetop handle 118, although aligned with thedrive shaft 104 on thedrive axis 105, is separated from thedrive shaft 104 by a distance D2, as shown inFIG. 2 . The separation (of distance D2) allows a user's arm to pass through thedrive axis 105 unimpeded when turning thecrank 110 to operate theauger 100 manually. The user can hold thetop handle 118 to steady theauger 100 during both manual and/or powered operation of theauger 100. The user can also provide a downward force along thedrive axis 105 using thetop handle 118. - As can be appreciated, in other embodiments the
top handle 118 may be positioned non-concentric (not aligned or not co-axial) with thedrive shaft 104 and thebit shank 112, at a distance away from thedrive axis 105 equal to the distance D2 of thecrank handle portion 124 away from the longitudinal axis of thedrive shaft 104, and on an opposite side of thedrive axis 105 of thedrive shaft 104. Accordingly, thetop handle 118 and crankhandle portion 124 can simultaneously be rotated about thedrive axis 105 to rotate thedrive shaft 104. - The
top handle 118 may also comprise arotatable hand grip 128 configured to rotate (or spin) about a longitudinal axis of thetop handle 118. Arotatable hand grip 128 allows a user to firmly grip thetop handle 118 while operating thecrank 110. - In the illustrated embodiment, the
top handle 118 includes atrigger 130 on top of therotatable hand grip 128 to activate thedrive motor 106. A user can grasp thehand grip 128 of thetop handle 118 in the hand and operate thetrigger 130 with, for example, the thumb. Thetrigger 130 causes thedrive motor 106 to spin thedrive shaft 104 and thebit 102. As can be appreciated, thetrigger 130 may be positioned other than on the top of thehand grip 128, so as to be operated by one or more different fingers. - The
trigger 130 may function in conjunction with another trigger 127 (shown inFIG. 2 ) on thehand grip 126 of thecrank 110 to provide a two-button activation safety mechanism. Thetrigger 130 of thetop handle 118 and thetrigger 127 of thecrank 110 may be configured to require concurrent activation in order to activate thedrive motor 106. Concurrent activation may require that the user place both hands on theauger 100, one hand on thetop handle 118 and the other hand on thecrank 110, to use the power-option of theauger 100, which can limit accidental or inadvertent activation of thedrive motor 106. -
FIG. 4 is an enlarged view of adrive motor 106 of the electric andmanual ice auger 100 ofFIG. 1 . Thedrive motor 106 enables the powered option of the electric andmanual ice auger 100. Thedrive motor 106 of the illustrated embodiment is electric and comprises a battery 132 to provide a source of electric power to thedrive motor 106. As can be appreciated, in another embodiment thedrive motor 106 may be other than electric powered. For example, thedrive motor 106 may be a fuel-powered engine. - The
drive motor 106 is coupled at a distal end to thedrive shaft 104 and is configured to rotate thedrive shaft 104 on (or about) thedrive axis 105. Thedrive motor 106 is also coupled to the lower crankarm 122. By coupling the lower crankarm 122 to thedrive motor 106, the crank 110 can be used to hold thedrive motor 106 rotationally fixed (not rotating around the drive axis 105) during power-only operation of theauger 100. The crank 110 can also be used to rotate thedrive motor 106 around thedrive axis 105 in the direction of drilling (the direction in which the one or moreice cutting blades 114 rotate when cutting ice) for either manual-only operation of theauger 100 or combined manual and power operation of theauger 100. - The
drive motor 106 may include an internal breaking mechanism and/orlocking mechanism 140 to lock thedrive shaft 104 relative to thedrive motor 106. Locking thedrive shaft 104 relative to thedrive motor 106 may enable thedrive motor 106 to be rotated manually, such as with the manual crank 110, to rotate thedrive shaft 104, thebit 102, and theice cutting blades 114. In one embodiment thelocking mechanism 140 may be a pin. In another embodiment, thelocking mechanism 140 may be a spring loaded pin. In another embodiment, thelocking mechanism 140 may include a button to activate an internal breaking mechanism. -
FIG. 5 is an enlarged view of abattery mount 134 of thedrive motor 106 ofFIG. 4 . As illustrated, the battery 132 of the illustrated embodiment is mounted on the side of thedrive motor 106. Thebattery mount 134 allows the battery 132 to quickly slide and lock into position, while also allowing quick release of the battery 132 for ease of charging. Thebattery mount 134 also allows a dead or drained battery to be exchanged for a charged battery. - As can be appreciated, in other embodiments the
battery mount 134 may be positioned in different configurations. For example, thebattery mount 134 may be positioned on a different side of the drive motor. Thebattery mount 134 may also be positioned on top of thedrive motor 106, so as to be in line with thedrive axis 105. Positioning the battery 132 in line with thedrive axis 105 can harness gravity to provide a balanced downward force, down the drive axis, to enhance effectiveness of theice cutting blades 114. - It will be obvious to those having skill in the art that many changes may be made to the details of the above-described embodiments without departing from the underlying principles of the invention.
