The present invention relates to ice fishing and more particularly, to a magnetic levitation spool assembly for ice fishing tip-ups.
A tip-up is a device used while ice fishing to suspend live or frozen bait at a set depth through a hole drilled in the ice. The tip-up detects when a fish strikes without the angler having to be in physical contact with the fishing gear. And when a fish does take the bait, a flag “tips up” (or the flag can “tip down”) to signal the angler that a fish has taken the bait. As a result, anglers can see the flag from a distance and can thus manage multiple holes at once, covering a larger area than with just an ice fishing rod.
Traditional tip-ups, however, succumb to the force of gravity during use, whereby separate components of the tip-up rub, resulting in friction, which in turn causes the separate components to not perform as desired. During winter conditions, this problem is amplified due to freezing rain, snow, and other harsh winter conditions that causes the mechanical parts to freeze together so that they do not spin or otherwise operate as designed. This results in the angler losing their catch more easily or seeing an increase in false flags (i.e., the fish takes the bait but, due to the resistance of the spinning components, drops it before the hook can be set). p Generally speaking, in freezing and wet conditions metal's performance substantially suffers, and specifically for tip-ups, the tip-up's metal components problematically freeze to other metal parts, locking up the tip-up's mechanical system. Metal on metal rubbing also increases friction points, inhibiting the effectiveness of the tip-up. The current solution is to use excess and potential environmentally harmful grease to reduce friction and/or eliminate separate components freezing together. This excess grease, however, may threaten the very specifies of fish the angler is aiming to catch, as well as create a mess for the angler.
Accordingly, there is a need for a magnetic levitation (maglev) spool assembly for ice fishing tip-ups. The maglev spool assembly may use two sets of opposing magnetized objects to suspend the spool assembly or a central portion thereof to eliminate the force of gravity that causes rubbing and friction between separate components along the spool assembly. As a result, the spool can spin more freely so that as the fish pulls the bait the hook is able to be set more efficiently as there is less resistance.
The present invention uses sets of magnets in opposing directions to create a suspended lift of the spool. The magnetic lift is greater than the weight of the parts and, as a result, the parts are suspended above each other reducing the friction caused by rubbing. The use of magnetic levitation spools of the present invention sees the same performance gains of that associated with high-speed magnetic levitation trains. By eliminating most of the friction caused by gravitational forces of metal-on-metal rubbing, the tip-up's overall performance improves.
In one aspect of the present invention, a magnetic levitation spool assembly for a tip-up device, the assembly providing the following: a shaft extending between a spool end and a trip mechanism end; a board engager disposed along the shaft between the spool end and the trip mechanism end; a first pair of magnetized objects between the spool end and the board engager; and a second pair of magnetized objects between the trip mechanism end and the board engager, wherein the first and second pair of magnetized objects magnetically repel each other to produce a gap between each pair of magnetized objects and the board engager.
In another embodiment of the present invention, the assembly includes the following: a spool connected to the spool end; a trip mechanism connected to the trip mechanism end; a magnetizable tube receiving the shaft, wherein the magnetizable tube is disposed between the spool end and the trip mechanism end, and wherein the board engager is connected to magnetizable tube, wherein the gap between the magnetizable tube and each set of one or more magnetized objects is magnetically urged by each set of one or more magnetized objects, wherein each set of one or more magnetized objects comprising a pair of magnetized objects; and a magnet cap between each pair of magnetized objects, wherein each magnetized object is slidably connected to the shaft.
In another embodiment of the present invention, a method of decreasing friction between a plurality of magnetizable components of a tip-up device, wherein the plurality of magnetizable components is connected along a shaft of a spool assembly of the tip-up device, the method includes the following: disposing at least two magnetized objects along the shaft, wherein each two adjacent magnetized objects of the at least two magnetized objects is separated by a magnetizable component of the plurality of magnetizable components, wherein the two adjacent magnetized objects magnetically repel said magnetizable component to produce a gap between said magnetizable component and each of the two adjacent magnetized objects.
These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.
The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
Referring to
The shaft 20, the spool 30 and the trip bar 40 of the maglev tip-up assembly 100 may be embodied on a maglev spool assembly 80 having a board engager 85 disposed along the shaft 20 between the spool 30 and the trip bar 40. The board engager 85 may be dimensioned and adapted to engage the board 10 along a board recess 15 so that in a horizontal orientation (not shown) the maglev spool assembly 80 may be received therein. Accordingly, the board engager 85 allows the maglev spool assembly 80 to move between a vertical orientation and a horizontal orientation. The board engager 85 may be embodied in or connected to a central tube 88. The central tube 88 may be stainless-steel or any other magnetizable material and have an inner opening through which the shaft 20 may slide therethrough.
The shaft 20 also provides at least a first and/or second magnetized objects 91 and 92 between the spool 30 and the board engager 85 and at least a first and/or second magnetized objects 91 and 92 between the tip bar 40 and the board engager 85, respectively, as illustrated in
In certain embodiments, the magnetized objects may be ⅜″×⅛″×⅛″in size. Though varying sizes of magnetized objects 91 and 92 could be used to create greater opposing magnetic forces. The total number of magnetized objects could also be reduced by modifying other manufactured parts of the maglev spool assembly 80. Magnetically conducive metals could replace two of the four magnets. In short, different size and strength magnets could be used to achieve the same magnetic levitation affect. Likewise, magnets are affixed the spool or spool assembly could be shuffled to achieve the same mechanical affect.
Furthermore, in certain embodiments, a tube cap 28 and a magnet cap 29, see
In some embodiments the board 10 may be wood, though is not limited to such material. In some embodiments the shaft 20 may be a stainless-steel or any other magnetizable material spool rod that is 13.75 inches in length, though the shaft 20 is not limited to such material nor dimensionality. In some embodiments the spool 30 may be nylon plastic, though is not limited to such material. In some embodiments the trip bar 40 may be a 303 stainless-steel or any other magnetizable material flag trigger pin though is not limited to such material. In some embodiments the flagpole 60 may be a stainless-steel material flag rod 16 inches in length, though is not limited to such material nor dimensionality. In some embodiments the flag 70 may be cloth, though is not limited to such material.
A method of using the present invention may include the following. The maglev spool assembly 80 disclosed above may be provided. In certain embodiments, a user does not have to set or manipulate any of the magnetized objects 91 and 92 provided as the unit comes completely assembled so that the user may to use the tip-up device as they would regularly. To use the tip-up assembly 100 one must release the flag 70 that fits into a hole in the spool 30. Then in some embodiments the user unlocks the maglev spool assembly 80. Once unlocked the angler would rotate the maglev spool assembly 80 until it is perpendicular with the base/board 10. Once fishing line (not shown) is spooled and the line is hooked and baited, the angler would set their appropriate depth and lay the base/board 10 over the hole they drilled in the ice. To set the tip-up, the angler pulls the flag down, and sets the flag set bar on the flag pin. When a fish takes the bait, the line will rotate the maglev spool assembly 80 shaft 20 causing it to spin, releasing the flag 70, indicating that a fish has taken the bait. To reel in the catch, the angler can choose to grab the spool and spin it by hand, or they can pull the line in by hand then spool the rest of the line after they realize their catch or miss.
A wireless (such as Bluetooth™) indicator connected to an angler's smartphone that alerts when a fish has taken the bait would add additional utility. Additionally, an attached electrically heated hole warmer to the wooden base could make the tip-up more effective. In some cases, during the night when visibility of the device is limited, lights will be added to the device to signal that a flag has been triggered.
In certain embodiments, an adjustable shaft collar line guide 21 may be provided. The adjustable shaft collar line guide 21 enables the angler to set a specific tension for varying sizes of live bait. An appropriate selectively set tension reduces the likelihood that the bait fish will unspool the line by swimming around—a common problem with tip-up devices. By tightening the tension, the present invention reduces the ability for the bait fish to unspool the line and ensuring the desired depth the angler set is always maintained.
