This application claims the benefit of priority based on Japanese Utility Model Application No. 2019-615, which is a prior application filed on Feb. 22, 2019. The entire contents of which are incorporated herein by reference.
The present disclosure relates to fishing gear, and more particularly to a method for controlling an electronic alarm for a fishing reel and an electronic alarm system for a fishing reel.
Fish habitats vary with changes in the food chain, and different types of fish have different water depths for their habitats. Usually, after finding the fishing depth at which fish can be caught, when the lead of the fishing line is thrown again, the fishing line is preferably unwound so as to be able to reach the exact same depth in order to find the fish accurately and to increase the probability that the fish can be caught. In the case of a conventional fishing reel, an angler usually remembers the color of the fishing line or fishes by estimating the depth of the fish's habitat by marking it with these methods having a low probability of catching fish. In the case of a fishing reel with a digital display (Patent Document 1), the depths of fish can be memorized, and the angler need only to memorize the length of the fishing line displayed on the LCD screen; and each time a fishing line is fed into a memory meter, fish can be found and the same kind of fish can be caught easily.
However, the fishing reel with digital display has the following disadvantages; first, focusing attention on the length of the fishing line shown on the LCD screen is necessary in order to respond immediately while feeding the fishing line. Also, the LCD screen needs to be accurately positioned in the housing during installation, and improper positioning can cause the screen to break and affect use, resulting in waste and susceptibility of the LCD screen to damage during use. Furthermore, if using a fishing reel with a digital display, the size is relatively large and the cost becomes high.

The shape of the second housing 6 is the same as that of the end side of the wire wheel 19 of the fishing reel, and screws 10 pass through the screw holes 9a of the second cover 9 and the screw holes 6a of the second housing 6 to attach the second assembly 40 to the end side of the wire wheel. The second housing 6 also serves as a wire wheel cover such that space can be saved and the fishing reel can be reduced in size.
When the button 2 is pressed and power is supplied from the battery 13 to turn on the circuit, the single chip microcomputer 17 detects a power-on signal, receives a power-on command, and starts data analysis and processing, and then the memorized water depth electronic alarm of the fishing reel begins to operate.
The one or more induction magnets 21 are fixed to the wire wheel 19 of the fishing reel. The wire wheel 19 is fixed to a wire wheel shaft 20 and attached to the fishing reel holder 18 to drive the rotational motion of the one or more induction magnets 21. The sensor 16 detects the motion of the one or more induction magnets 21, converts the motion into one or more electric detection signals and transmits the one or more signals to the single chip microcomputer 17 where the one or more signals are processed. The single chip microcomputer 17 is able to be receive the electric detection signals from the sensor 16 and to determine the rotational movement of the wire reel 19 (fishing reel) by calculations and analysis based on the electric detection signals from the sensor 16. Then, depending on the analysis result, the single chip microcomputer 17 transmits a memorized water depth transmission command to the buzzer 12 with a value substantially indicating, approximating, or estimating the length of the unwound fishing line as the memorized water depth, and the buzzer 12 is then instructed to sound an alarm indicating that the memorized water depth has been reached.
In the present disclosure, circuit diagrams disclose the operation of the present embodiment.
The buzzer 12 is electrically coupled with the single chip microcomputer 17 so as to be able to sound at least one alarm in response to at least one instruction from the single chip microcomputer 17. In the embodiment, the buzzer 12 is electrically connected to PIN5 and configured to receive instructions to sound the at least one alarm from the single chip microcomputer 17. A plurality of buzzers can be provided instead of one buzzer 12.
The battery 13 is configured to supply the single chip microcomputer 17, the sensor 16, and the buzzer 12 with electric power. The battery 13 is connected to a VCC pin PIN2 and a VSS pin PIN4 of the single chip microcomputer 17 to supply power to the single chip microcomputer 17. In the embodiment, the battery 13 is electrically coupled with all circuits requiring DC3V voltage. The present disclosure is not limited to the battery 13 of the current embodiment, and one or more types of power sources may be used as the battery 13 as long as the necessary power is able to be supplied to the necessary elements.
The button 2 is electrically coupled with the single chip microcomputer 17 so as to be able to transmit reception of at least one operation by a user to the single chip microcomputer. The button 2 is electrically connected to the single chip microcomputer 17 via a KEY1 pin PIN16 such that on/off signals from the button 2 may be input to the single chip microcomputer 17. Note that while this embodiment utilizes a button, any type of input means capable of detecting a user's operations can be used in place of a button. By performing an operation of pressing and releasing the button 2, the single chip microcomputer 17 can be initiated, terminated, or triggered. For example, by performing an operation of pressing and releasing the button 2, the single chip microcomputer 17 may start up, may shut down, may be triggered to detect a current point, or may memorize some current points as will be described below, in its built-in memory.
The first sensor reed switch S3 and the second sensor reed switch S4 are used to detect the position of the one or more induction magnets 21 (see
When the one of the one or more induction magnets 21 is close to either the first sensor reed switch S3 or the second sensor reed switch S4, the contactor in the sensor 16 (the corresponding reed switch S3 or S4) causes the related signal line in
The single chip microcomputer 17 is configured to analyze the electric detection signals and determine whether the fishing line is being unwound or rewound. In other words, the single chip microcomputer 17 is configured to determine the direction of rotation of the fishing reel based on the electric detection signals from the sensor 16.
With respect to the present embodiment, when the fishing line is being released, each of the one or more induction magnets 21 first reacts with the first sensor reed switch S3, and subsequently with the second sensor reed switch S4. Accordingly, the single chip microcomputer 17 receives a detection signal from the first sensor reed switch S3 first and then a detection signal from the second sensor reed switch S4. Based on this order the single chip microcomputer 17 determines that the fishing line is being released (unwound).
Conversely, when the fishing line is being rewound, the single chip microcomputer 17 receives a detection signal from the second sensor reed switch S4 first, and then a detection signal from the first sensor reed switch S3. Based on this order the single chip microcomputer 17 determines that the fishing line is being rewound.
Further, the single chip microcomputer 17 is configured to calculate and analyze the detection signals from the sensor 16 and determine a current point based on a value substantially indicating or approximating or estimating the length of the fishing line which is calculated using the detection signals. In the present embodiment, the number of the detection signals is counted and used as the value of the current point. The calculated current point or any related information can be memorized in the memory of the single chip microcomputer 17 or any other suitable memory.
The memorized water depth electronic alarm for a fishing reel of the present disclosure has only one button, and this button is an on/off switch and a memory switch; except for the shutdown operation, the memory function is activated once each time the button is pressed, a value substantially indicating or approximating or estimating the length of the fishing line at that time is memorized, and when the value of the fishing line is again unwound to the memorized water depth, the alarm is automatically sounded; thereby, informing the angler that the position of the school of fish has been reached.
In
In order to operate the electronic alarm system for fishing, before releasing the fishing line the following process is used. As shown in
The fishing line is then released in order to begin fishing. The single chip microcomputer 17 then determines whether the button 2 is pressed for a first period of time (e.g. 5 seconds) (STEP 3). When the button 2 is pressed for the first period of time (STEP 3, YES), the single chip microcomputer 17 memorizes the current point at a time when the button 2 is pressed for the first period of time as a target point TP (STEP 4). In this embodiment, in STEP3, the current point at the time when the button 2 is pressed is set to zero. That is, when an angler finds a position where one or more fish are present and presses the button 2 down, the target point TP is memorized in the memory. When the button 2 is not pressed for the first period of time (STEP 3, NO), the process returns to STEP 3 again.
In the casting period PA that the target point is memorized, while the angler is seeking fish, the current point arbitrarily changes in response to the angler's operation and/or the natural environment. That is, the angler can freely move a fishing hook or lure between the arbitrary positions at arbitrary times in arbitrary directions in the water until the angler finds a fish (e.g. until the angler realizes a fish's contact with the fishing gear, such as changes of tension or movement of the fishing line, movement of a fishing float, or the like) and then press the button 2 down. In
After the target point TP is memorized, the single chip microcomputer 17 continues to detect the current point and determines whether the current point is stopped at a point different from the target point TP (STEP 5). While the current point continues to change (STEP 5, YES), the process returns to STEP 5 again. When the current point stops changing for a predetermined period of time (STEP 5, NO), the single chip microcomputer 17 memorizes the current point at the time when the current point stops changing for the predetermined period of time as the reference point RP (STEP 6). In the embodiment, the reference point RP has a positive value different from the value of the target point TP.
In a second embodiment that the following part of the first embodiment is modified, during the casting period PA, the target point TP may be updated when the button 2 is pressed for the first period of time again. For example, the processes may be modified such that when the current point continues to change (STEP 5, YES), the process returns STEP 3 (and STEP 4). In a third embodiment that the following part of the first and/or second embodiments are modified, the single chip microcomputer 17 may send instructions to the buzzer 12 to sound an alarm that indicates completion of memorizing the target point TP in STEP 4. Also note that a variable type of alarm may be used for the starting alarm and/or the alarm that indicates completion of memorizing the target point.
In the embodiments, with respect to the casting period PA that the target point TP is memorized, after rewinding the line, the angler is to position fishing tackle, such as a lure, a hook, or the like in a standard position out of the water. Thus, the reference point is deemed to represent that the fishing elements (the fishing tackle) attached to the end portion of the fishing line are near the fishing rod. Based on such consideration, in the fishing line casting period PB after the casting period PA as shown in
As shown in
When the single chip microcomputer 17 determines that the current point is not equal to any of the first predetermined values and/or that the fishing line is not being released (STEP R2, NO), the single chip microcomputer 17 determines whether the current point is equal to the target point TP in a state in which the fishing line is being released (STEP R4). When the single chip microcomputer 17 determines that the current point is equal to the target point TP in a state in which the fishing line is being released (STEP R4, YES), the single chip microcomputer 17 sends instructions to the buzzer 12 to sound an arrival alarm (e.g., an alarm having a duration of 5 seconds) (STEP R5). In a forth embodiment that the following part of the first, second, and/or embodiments are modified, the single chip microcomputer 17 may also send instructions to the buzzer 12 to sound an arrival alarm (e.g., an alarm having a duration of 5 seconds) when the current point is equal to the target point TP in a state in which the fishing line is being rewound.
When the single chip microcomputer 17 determines that the current point is not equal to the target point TP and/or that the fishing line is not being released (STEP R4, NO), the single chip microcomputer 17 determines whether the difference between the current point from the reference point RP is equal to at least one second predetermined value in a state in which the fishing line is being rewound (STEP R6). When the single chip microcomputer 17 determines that the difference of the current point from the reference point RP is equal to at least one second predetermined value in a state in which the fishing line is being released (STEP R6, YES), the single chip microcomputer 17 sends instructions to the buzzer 12 to sound a second predetermined alarm (e.g., an alarm having a duration of 1 second) (STEP R7).
When the single chip microcomputer 17 determines that the difference of the current point from the reference point RP is not equal to any of the second predetermined value and/or that the fishing line is not being rewound (STEP R6, NO), the single chip microcomputer 17 determines whether the difference of the current point from the reference point RP is equal to zero in a state in which the fishing line is being rewound (STEP R8). When the single chip microcomputer 17 determines that the difference of the current point from the reference point RP is equal to zero in a state in which the fishing line is being rewound (STEP R8, YES), the single chip microcomputer 17 sends instructions to the buzzer 12 to sound an alarm for the reference point RP (e.g. 5 second) (STEP R9) and the fishing line casting period PB terminates.
When the single chip microcomputer 17 determines that the difference of the current point from the reference point RP is not equal to zero and/or that the fishing line is not being rewound (STEP R8, NO), the process returns to STEP R2 again. Further, for each following fishing line casting period PB after the fishing line casting period PA when the target point is memorized, the processes shown in
The first predetermined alarm(s) can mark timings when a current point is approaching the target point TP, i.e. a lure or a hook is approaching a place where fish are likely to be present in the water. The alarm for the target point TP can mark a timing when the angler has to delicately, carefully pay attention to catch fish.
In many cases, once the angler finds or catches a fish, the angler tries to direct the lure or the hook to the same or near position where the fish were found due to the high possibility of presence of other fish. In such cases, with respect to the fishing line casting(s) after the fishing line casting that the fish were found, the fishing conditions of the angler's position, time of the day, natural environment conditions such as weather, water temperature, etc. are similar to the conditions of the fishing line casting during which the fish were found. Thus, the target point TP is able to be used as an indicator to announce the possibility of presence of fish in the fishing line casting of period PB.
The first predetermined alarm and/or the arrival alarm effectively help anglers to pay more attention at the important timing to take more appropriate actions or strategies to catch fish. For example, the first predetermined alarm and/or the arrival alarm for the target point TP effectively increases the possibility of successful catch of fishes and anglers are able to achieve more excited feeling with respect to the approach.
Also, the arrival alarm for the target point TP which is longer than or distinct from the first predetermined alarms effectively helps anglers to positively realize the sign of any fish. As a result, anglers can enjoy more successful fishing.
During the fishing line casting period PB, in order to find fish, the angler may arbitrarily change the positions, exemplified by positions corresponding to arbitrary point AP2 or AP3 as shown in
As shown in the embodiment of
The number of the first predetermined values may be designed to be changed. Further, for example, the first predetermined values may be set such that the values represent approximate values roughly corresponding to positions, such as 1 m, 3 m, 5 m, and 7 m, apart from the position that the fish was found. In the embodiments, the first predetermined values are positive values to indicate that the target point TP is approaching. However, in a fourth embodiment that the following part of the first, second and/or third embodiments are modified, the first predetermined values may be negative values to indicate that the target point TP is going away and may include both positive values and negative values. The first predetermined alarm for each positive value may be different from the first predetermined alarm for each negative value.
The second predetermined alarm(s) can mark timings when a current point is approaching the reference point RP, i.e. the fishing tackle and/or one or more fish are approaching the water surface. In other words, the alarm for the reference point RP can mark a timing when the angler has to delicately, carefully pay attention to catch fish as well as a timing when the angler has to pay attention to prevent fishing tackle such as a lure, hook, or the like from hitting the fishing rod.
As shown in the embodiment of
The number of the second predetermined values may be changed. For example, the second predetermined values may be set such that the values represent approximate values roughly corresponding to positions, such as 1 m, 3 m, 5 m, and 7 m, apart from the position of the fishing rod defined by the reference point RP. In a fifth embodiment that the following part of the first, second, third, and/or fourth embodiments are modified, the second predetermined alarm for each second predetermined value may be different from each other and/or from the first predetermined alarm.
In addition, when a fish which is engaged with a lure or a hook is approaching the water surface, delicate operations by the angler are required, since the fish tries to do their best to escape in order not to be caught at the final stage near the water surface.
In conventional fishing, anglers were not able to clearly realize the fish's position before the fish approached the water surface enough to be visible in the water. However, the second predetermined alarms can clearly indicate the position of fish to be caught to anglers regardless the visibility of the fish. Thus, this useful information enables the angler to pay more attention to a fish to take more appropriate actions or strategies in order to positively catch the fish. For example, the angler can prepare a net for scooping up fish and/or carefully operate the rod and/or the fishing reel, or the like. Thus, the second predetermined alarms and the alarm for the reference point RP effectively increases the possibility of successful catching of fish and anglers are able to experience a greater sense of excitement during the approach.
Also, the alarm for the reference point RP which is longer than or distinct from the second predetermined alarms effectively helps anglers to prevent fishing tackle such as a lure, hook, or the like from hitting the fishing rod. As a result, anglers can enjoy more successful fishing with suppressed possibility of damage of the fishing element attached to the end portion of the fishing line and the rod and/or elements provided with the rod.
In the first embodiment, by utilizing the number of the detection signals for determining a current point and setting the first and/or second predetermined values depending on the diameters of fishing reels, more accurate determination of the position of the fishing line becomes possible with a simple configuration.
Note that a variable type of alarm may also be used for the alarm for the starting alarm and the first predetermined alarm, the second predetermined alarm, the arrival alarm, and the alarm for the reference point. Further, the first predetermined alarms for each predetermined value can be different from each other. The second predetermined alarms for each predetermined value can be different from each other.
When the target point has not yet been set, the processes which are shown in
Further, in a further modified embodiment, each depth of STEP R2 and STEP R4 may be determined regardless of the direction of the fishing line. However, each depth of STEP R2 and STEP R4 may be determined only with respect to one direction in which the fishing line is being either released or rewound. In another embodiment, any calculation method can be applied as long as each comparison of STEP R2 and STEP R4, STEP R6, STEP R8 is substantially possible.
When actually fishing, the line may be unwound to the target position and the line may not be immediately stopped, i.e., the line may continue to be unwound for a period of time even if the alarm sound stops, and the value of the line may be longer than the actual water depth, in which case the reel may be rotated to bring the extra line in and automatically sound when the memory water depth is reached again, thereby informing the angler that the position of the fish group has been reached.
The memorized water depth electronic alarm for a fishing reel of the present disclosure can be adjusted for the memory water depth at any time. When a new memorized water depth (the new target point) has been set, the previously memorized water depth (the previous target point) is automatically canceled, and the convenience of operation is superior.
In addition, the memorized water depth electronic alarm for a fishing reel of the present disclosure has a simple structure, low memory requirements for single-chip microcomputers, which means that small single-chip microcomputers can meet usage requirements, reduce material costs, save resources, protect the environment, and be easier and more convenient to use.
