Description
- The present invention relates generally to an ice boring apparatus, and more particularly to an improved ice auger, which structure is preferably simplified.
- Fishing is a popular activity for relaxation. However, the ice will be formed over the water in some fishing fields around the rivers, lakes, beaches, etc. in the winter or cold zones. For this reason, ice auger, an apparatus for boring the ice, was invented for the fishers to enjoy fishing even in the winter or cold zones.
- U.S. Pat. No. 4,819,744 discloses an ice auger. It is to be noted that the numerical references recited hereinafter in this paragraph are directly quoted from U.S. Pat. No. 4,819,744. The ice auger primarily comprises a drive unit, shown as an overall assembly of all components in the right side of FIG. 1 of U.S. Pat. No. 4,819,744, and a boring unit, shown as an overall assembly of all components in the left side of FIG. 1 of the '744 patent. The drive unit, which is arched, has a
guide pad 32 on its top and a rotatable drive handle 30 at its middle section. The boring unit is generally composed of an outerream control sleeve 50, an auger blade 65, a ring 63, aninner drive bar 20, a pair of reaming blades 56 with two slots 60, and two ice boring blades 38. The outerream control sleeve 50 can be inserted through by a bottom section of the drive unit and an upper section of theinner drive bar 20, which top can be coupled with the bottom of the drive unit. The outerream control sleeve 50 is spirally surrounded with the auger blade 65 and has a bottom to be fastened to the ring 63, to which bottom side the reaming blades 56 is pivoted. Theinner drive bar 20 has a bottom fastened with the ice boring blades 38 and extended with twocamming support bars 44, which are respectively pivoted to the slots 60 of the reaming blades 56 by two ice reaming blade camming pins 46. The operational process of the ice auger is described hereinafter. Put the ice auger standing upright on the ice 14, the users with one hand holding theguide pad 32 on the top of the drive unit to press downwardly and with the other hand holding thedrive handle 30 at the middle section of the drive unit, turning thedrive handle 30 in lateral direction. The drive member has the bottom coupled with the top of theinner drive bar 20, and theinner drive bar 20 has thecamming support bars 44 at its bottom to drive the reaming blades 56, the rings 38, and theouter drive bars 50, so that the reaming blades 56 and the ice boring blades 38 can be rotated to bore. The ice chipping formed while boring the ice 14 follows the rotation of the overall boring unit, through the ring 63, and it is ejected upward along the auger blade 65, such that a hole for fishing will be bored through the ice 14. - The foregoing ice auger includes at least below drawbacks.
- 1. The structure of the ice auger is over-complicated and the production cost is relatively high.
- 2. Although the ice auger can be generally disassembled as an arched drive unit and a boring unit, the boring unit is still huge and heavy and inconvenient to be carried.
- The primary objective of the present invention is to provide an improved ice auger, which structure is preferably simplified and production cost is low.
- Another objective of the present invention is to provide an improved ice auger, which disassembled components are small-sized and convenient to be carried.
- To achieve the objectives of the present invention, the ice auger of the present invention includes an upright bar, a drive member coupled with a top of the bar, and a saw barrel. The saw barrel, which is circular mug-shaped with a downward opening, has a top side fastened to a bottom of the bar, pores at its top side, saw blades on its periphery of the bottom side, and a chipping-ejecting blade upward spirally extended from an outer sharp edge of the said saw blade along the outer periphery of said saw barrel. According to the foregoing three components of the present invention, the ice auger is provided with a preferably simplified structure and convenient to be carried after being disassembled.
- The substantial structure and features of the present invention will be readily understood upon a thoughtful deliberation of the following detailed description of preferred embodiments of the present invention with reference to the accompanying drawings.
- FIG. 1 is a perspective assembly view of a preferred embodiment of the present invention;
- FIG. 2 is a longitudinal cross-sectional view of the preferred embodiment of the present invention;
- FIG. 3 is a perspective exploded view of the preferred embodiment of the present invention; and
- FIG. 4 shows the preferred embodiment of the present invention in practice.
- Referring to FIGS.1-3, an improved
ice auger 10 of a preferred embodiment of the present invention includes abar 20, adrive member 30 detachably mounted on a top of thebar 20, and asaw barrel 40 detachably fastened to a bottom of the bar. - The
bar 20, which is an upright straight bar, has a hexagonal connectingpost 21 at a top end thereof, thepost 21 having a throughhole 22 horizontally therethrough, and a threadedpost 23 at a bottom end thereof. - The
drive member 30 for rotatably driving thebar 20 and thesaw barrel 40 is rail-shaped and has an uprightcylindrical coupler 31 at a center thereof. The coupler has an axialhexagonal hole 32 and twoopposite vents 33 radially therethrough, and the connectingpost 21 of the top of thebar 20 is inserted into thehole 32, and thevents 33 and the throughhole 22 correspond to and communicate with each other. Furthermore, apin 34 is inserted into thevents 33 of thecoupler 31 and the throughhole 22 of the connectingpost 21, and has aring 35 at one end thereof. The main structure of thedrive member 30 can be steering-wheel-shaped, or arched as the '744 patent, therefore, thedrive member 30 is not actually confined to be rail-shaped. Moreover, the way to connect thedrive member 30 and thebar 20 is not actually confined to the foregoing engaged and pin-fastened structure, and there are still other equivalent technology to be applied, such as to-be engaged and to-be bolt-fastened, to-be directly screwed with each other, to-be directly solder-bonded, and so on. - The
saw barrel 40 has a circular mug-shapedmain body 41 with a downward opening. Themain body 41 includes aconnecting tube 42 having an inner thread and protruding upward at a center thereof to be clockwise screwed into the threadedpost 23 of thebar 20, and afew pores 43 on its top side, and threesaw blades 44 in an arrangement of equivalent angle integrally downwardly protruding from the periphery of its bottom, and three chipping-ejectingblades 45 counterclockwise upward spirally extended from the outer sharp edge of thesaw blades 44 on the periphery ofmain body 41. The way to connect thesaw barrel 40 and thebar 20 can be similar to foregoing engaged and pin-fastened structure of thebar 20 and thedrive member 30, or other equivalent technology of to-be engaged and to-be screw-fastened, to-be directly solder-bonded, etc. Therefore, it's not actually confined to the way of to-be screwed. Likewise, the saw blades are not required to be confined to specific shape and quantity, and actually also can be detachable but not required to be integrally formed. - The interrelation among the components of the ice auger of the preferred embodiment is recited above and the operational process, as shown in FIG. 4, is described hereunder. Put the
ice auger 10 standing on theice 50, users with two hands holding two ends of thedrive member 30 to rotate clockwise, and thebar 20 drives thesaw barrel 40 to rotate on the same spot. Note that thebar 20 and thesaw barrel 40 are also clockwise screwed tight such that they are not worried to be screwed loosely. Then, thesaw blades 44 cut out a circular face on theice 50 along a fixed circle track, i.e. a bottom fringe of thesaw barrel 40, and further, it cuts out anice column 51. As a result of thepores 43 located on the top side of thesaw barrel 40, the top side of thesaw barrel 40 is partial wide-open to prevent a closed chamber from being formed in thesaw barrel 40 which causes that the air is compressed to form an expansive resistance in the process of boring and users have to operate theice auger 10 more laboriously while boring theice 50. The ice chipping formed while boring theice 50 is ejected counterclockwise upward along the chipping-ejectingblades 45 when thesaw barrel 40 clockwise downwardly bores theice 50. - Furthermore, the
ice column 51 in thesaw barrel 40 is detached from theice 50 after theice 50 is bored through. The outside air enters thesaw barrel 40 through thepores 42, so that theice column 51 can be easily detached from thesaw barrel 40 while withdrawing theice auger 10 from theice 50. - Moreover, the applicant would like to recite herewith that the pores are designed to make the top side, or the outer periphery beside the top side of the saw barrel partial wide-open, so that the pores are not confined to specific location, shape, or quantity.
- To conclude from the above recitation, the improved ice auger of the present invention has advantages hereunder compared with the prior art:
- 1. The structure of the present invention is dramatically simplified and the production cost can be reduced.
- 2. The present invention can be disassembled as small components such that it's very convenient to be carried.
