Description

Description THE MULTI ELECTRON FLOAT

Technical Field

[1] The present invention relates to a multi-function electronic fishing float, and more particularly, to a multi-function electronic fishing float that has an identification number and enables easy recognition of a fish's bite by utilizing radio frequency (RF) communication and signals (sound, vibration, or light), wherein when a fish bites or is hooked, the RF signals are automatically generated and the generated RF signals are sent to a receiver, thereby clearly recognizing the bite or hooking of a fish through light, vibration, or sound outputted from the receiver, without checking the fishing float with an angler's eyes.

[2] Additionally, a multi-function electronic fishing float according to the present invention step by steps sends to a receiver the signals sensed by means of sensors sensing the position of separable circular magnets mounted on a body float and also checks the existence of a fish school through the image displayed on a monitor both during day time and night time.

[3]

Background Art

[4] Generally, basic fishing tackles such as a fishing rod, line, hook, float, and bait are required for fishing.

[5] Presently, various types of fishing floats are being used. The fishing floats are generally formed of materials such as rigid synthetic resin or wood, having an air pocket formed therein to provide buoyancy.

[6] Among such fishing tackles, the fishing float is used to allow an angler to recognize a bite or hooking of a fish in water and, particularly, a proper fishing float is used according to the depth of the water.

[7] The fishing float maintains a state that its upper part comes up above the water surface, and moves upwards/downwards in response to the fish's bite, which makes an angler recognize the bite or hooking of the fish.

[8] Accordingly, an angler may consider a correct time of pulling a fishing rod and decide whether to pull the fishing rod or not. However, in the case of fishing with a conventional fishing float, the fishing float with its upper part coming up above the water surface easily moves due to waves generated by wind or flowing water. Therefore, the angler faces difficulties in recognizing whether the movement of the float is caused by the fish's bite or by the waves.

[9] Accordingly, there may be a problem of missing a fish, because a fishing rod is not pulled at a correct time in response to the fish's bite, and pulling the fishing rod is not instantly performed.

[10] Additionally, an angler has to watch the float continuously during the fishing. If the fishing is continued for a long time, the angler may face problems of feeling stress and fatigue due to strain in eyes, bloodshot eyes, or losing its eyesight or having an eye trouble in the worst case.

[11] Further, an angler who does not have many experiences in fishing does not feel any pleasure in fishing because the fish taking bait or hooked is frequently missed, which fails to give happy fishing to the angler.

[12]

Disclosure of Invention Technical Problem

[13] Accordingly, the present invention has been made in view of the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a multi-function electronic fishing float that obtains the information on a fish's bite or hooking through radio frequency (RF) signals, thereby increasing the number of fishes caught.

[14] It is another object of the present invention to provide a multi-function electronic fishing float that checks the existence of a fish school by means of ultra sound sensors mounted at the inside of a lower cap coupled to the lower portion of a body thereof, such that the depth and temperature of the water in which lots of fishes are collected are recognized and the steps of the fish's bite can be sensed by the ultra sound sensors, thereby providing happy fishing to an angler.

[15] It is another object of the present invention to provide a multi-function electronic fishing float that recognizes the state in water by means of a camera mounted into a lower cap, thereby increasing a fish's bite and hooking by using lure or live bait in accordance with the kinds of fishes.

[40] As shown in FIGS.1 to 8, the multi- function electronic fishing float according to the present invention has a body 10 having a plurality of through-holes 10a formed along the outer circumferential surface thereof, a wing part 11 formed at the both sides thereof, a space portion 11a formed at the inside of the wing part 11 and adapted to provide buoyancy so as to allow the fishing float to be floated on the water, and a plurality of fixing holes 1 Ib formed on the bottom portion of the wing part 11.

[41] The body 10 has an approximately oval-shaped coupling member 12 at the upper end part along the outer circumferential surface thereof, and the coupling member 12 has a plurality of coupling protrusions 12a formed spaced apart from each other on the top surface thereof. Also, the coupling member 12 has a coupling groove 12b formed along the top end periphery thereof.

[42] The coupling member 12 has a cap-coupling rib 13 formed at the center of the top surface thereof, and the cap-coupling rib 13 has a cap-coupling through-hole 13a formed vertically along the center portion thereof.

[43] An upper cap 20 is coupled to the body 10 by means of the coupling protrusions 12a and the coupling groove 12b formed on the coupling member 12, so as to prevent water from being introduced to the space portions 11a formed in the wing parts 11 of the body 10. And, the body 10 has the plurality of fixing holes 1 Ib formed on the lower portion thereof.

[44] The body 10 further has an electrode switch 14 mounted at the bottom of the space portion 1 Ia of the wing part 11 at one side thereof, and the electrode switch 14 serves as a switch for supplying power through a small amount of current flow by the electrolytes contained in water when the electronic fishing float comes into contact with the water.

[45] The upper cap 20, which is adapted to be coupled to the upper end circumference of the body 10, has a coupling hole 20a formed at the center of the upper end thereof, and the coupling hole 20a is coupled to a fixing cap 22 to which a rubber ring 22a is coupled.

[46] An antenna 21 is mounted at one side of the coupling hole 20a so as to perform radio frequency communication.

[47] A charging hole 20b is formed at the other side of the coupling hole 20a, and a battery-charging cap 23 is insertedly coupled to the charging hole 20b. The battery- charging cap 23 has a rubber ring 23a mounted along the outer periphery thereof so as to prevent water from entering the charging hole 20b.

[48] A lower cap 30 is mounted at the lower portion of the body 10 and has body- coupling protrusions 31 formed at one side thereof in such a manner as to be coupled to the fixing holes 1 Ib of the wing part 11.

[49] The lower cap 30 has a center hole 32 formed at the center of the inside thereof and a mounting protrusion 33 formed at both sides of the center hole 32, the mounting protrusion 33 having a mounting groove 33a formed along the inner periphery thereof.

[50] A body float 40 is made of a paulownia tree so as to allow the hook with a bait to be placed at a predetermined depth in the water, and it is moved upwardly and downwardly at the inside of the body 10.

[51] The body float 40 has a through-hole 41 formed extended from the upper portion and to the lower portion thereof in such a manner as to insert the fishing line thereinto.

[52] Also, the fishing line inserted through the through-hole 41 is fixed at the top and bottom ends of the body float 40 by means of a knot (not shown) or a rubber ring.

[53] The body float 40 has fixing grooves 42 formed along the upper and lower outer peripheries thereof and a separable circular magnet 43 mounted along each of the fixing grooves 42.

[54] Also, the body float 40 has a spring 44 mounted at the lower portion thereof in such a manner as to be placed at the inside of the body 10, thereby allowing returning to an original position of the body float 40.

[55] The wing part 11 formed on one side of the body 10 has a fish's bite-checking sensing unit 50 adapted to sense the positions of the separable circular magnets 43 mounted on the body float 40, and the fish's bite-checking sensing unit 50 includes a first sensor 51, a second sensor 52, a third sensor 53, and a fourth sensor 54.

[56] So as to sense a fish's school, a depth of water, and a temperature of water, a plurality of ultra sound sensors 60 are insertedly fit to the mounting grooves 33a of the lower cap 30.

[57] At one side of the center hole 32 of the lower cap 30 is provided a camera 70 that photographs the state around the electronic fishing float, thereby giving information on the surrounding state around the float to an angler, and a light 71 is mounted at the opposite side to the camera 70 with respect to the center hole 32, so as to emit light when the camera 70 is operated.

[58] A printed circuit board (hereinafter, referred to as 'PCB') 80 is mounted into the space portion 1 Ia of the wing part 10 at one side of the body 10 so as to send the communication signals and image data signals outputted from the fish's bite-checking sensing unit 50 placed at the wing part 11 of one side of the body 10 and the ultra sound sensors 60 and the camera 70 mounted in the lower cap 30 to a radio receiver 2 held by an angler.

[59] The PCB 80 includes an ultra sound signal rectifier (not shown) for rectifying and filtering the signals outputted from the ultra sound sensors 60, an A/D converter (not shown) for converting the image signals outputted from the camera 70 into a digital signal, and a micro control unit (now shown) for controlling the signals outputted from the A/D converter and sending signals of data on the position of the fish's school, fish's hooking, biting, surrounding image, depth of water, and temperature of water, thereby allowing the angler to recognize the data through the radio receiver 2.

[60] Further, a radio transmitter (not shown) is mounted on the PCB 80 so as to send the signals outputted from the micro control unit to the radio receiver 2.

[61] Also, the upper cap 20 coupled to the upper portion of the body 10 has an auxiliary

PCB 90 mounted at the inside thereof, and the auxiliary PCB 90 includes a power circuit (not shown) and a battery (not shown) adapted to supply power necessary for the fish's bite-checking sensing unit 50, the ultra sound sensors 60, the camera 70, the light 71 and the PCB 80, the battery being formed of a rechargeable battery that recharges power.

[62] The battery is a lithium ion polymer battery, thereby increasing an economical value and overcoming environmental problems.

[63] So as to conduct fishing by using the multi-function electronic fishing float as constructed above, first, the fishing line is inserted sequentially into the fixing cap 22 of the upper cap 20 coupled to the upper portion of the body 10, the through-hole 41 formed along the body float 40, and the center hole 32 of the lower cap 30.

[64] The knot or rubber ring as generally used is formed on the top and bottom sides of the body float 40 so as to allow the fishing line to be operated cooperatively with the body float 40.

[65] At the state where the fishing line is adjusted in length by the formation of the knot or rubber ring, if the electronic fishing float is put in the water, the electrode switch 14 mounted on the wing part 11 of one side of the body 10 come into contact with the water, and at this time, the electrode switch 14 serves as a switch for supplying power through a small amount of current flow by the electrolytes contained in the water.

[66] Therefore, the power of the battery mounted at the inside of the upper cap 20 is supplied to the fish's bite-checking sensing unit 50, the ultra sound sensors 60, the camera 70, the light 71 and the PCB 80.

[67] At the state where the fishing line is adjusted in the length, it is put in the water, and the position of the fishing hook is adjusted by an angler.

[68] At this time, the position of the fishing hook is adjusted by recognizing the state where the electronic fishing float 1 is coming up above the water surface, and in more detail, the position of the fishing hook is recognized in accordance with the position of the body float 40 mounted at the inside of the body 10.

[69] Referring to setting the position of the fishing hook through the body float 40, a sinker having a predetermined weight, which is mounted on the fishing line above the fishing hook, is put into the water together with the electronic fishing float 1.

[70] If the fishing hook abuts against the bottom surface in the water, the body float 40 mounted at the inside of the body 10 comes into contact with the top end portion of the body 10, and a signal from the separable circular magnet 43 on the body float 40 is sent to the first sensor 51 of the fish's bite-checking sensing unit 50 mounted in the space portion 1 Ia of the body 10.

[71] If the signal is sent to the micro control unit of the PCB 80 in the body 10, the micro control unit sends the signal to the radio receiver 2 held by the angler by means of the radio transmitter, thereby permitting the angler to recognize that the fishing hook comes into contact with the bottom surface in the water.

[72] After recognizing, the angler draws the fishing rod from the water and adjusts the length of the fishing line. After that, the fishing line is put in the water again.

[73] The position of the body float 40 is recognized at the state where the electronic fishing float 1 is floated in the water, and at this time, it is checked by the radio receiver 2 whether the separable circular magnets 43 mounted on the body float 40 come into contact with the fish's bite-checking sensing unit 50 mounted in the space portion 1 Ia of the body 10.

[74] At this time, if the separable circular magnet 43 mounted on the upper portion of the body float 40 is placed between the first sensor 51 and the second sensor 52 of the fish's bite-checking sensing unit 50, it is recognized that the position of the fishing hook is at an optimal position.

[75] As mentioned above, at the state where the weight of the fishing hook is appropriately adjusted in accordance with the buoyancy of the body float 40, it is detected whether there is a fish's school around there.

[76] So as to detect the fish's school, the button on a keypad of the radio receiver 2 is pressed to allow the fish's school to be detected through the ultra sound sensors 60 mounted at the inside of the lower cap 30.

[77] If it is recognized that there is no fish around the electronic fishing float 1 after detecting the fish's school through the ultra sound sensors 60, a detecting point is moved to detect whether there is the fish's school there. [78] If the fish's school is detected, also, the kinds of fishes can be recognized, and at this time, the camera 70 and the light 71 mounted at the inside of the lower cap 30 are operated to check the state in the water. [79] That is, the image signal photographed by the camera 70 is sent to the micro control unit mounted on the PCB 80, and the signal sent to the micro control unit is sent to the radio receiver 2 via the radio transmitter and the antenna 21 mounted on the upper cap

20. [80] The image signal sent to the radio receiver 2 is displayed on a monitor to permit the angler to check the kinds of fishes, and the image displaying can be apparent to those skilled in the art. Therefore, an explanation on the technique for image displaying will be avoided for the brevity of the description. [81] That is, the thickness of the fishing line, the position of the fishing hook, and the kind of bait can be varied in accordance with the kind of fishes, thereby increasing the fish's bite and hooking. [82] As mentioned above, at the state where the state of the water around the fishing bait is checked through the ultra sound sensors 60 and the camera 70, the fishing is conducted by using lure bait (artificial bait) or live bait (using a live object). [83] If the fish's bite starts at the state where the fishing rod is put in the water, the body float 40 mounted at the inside of the body 10 is moved while the body 10 of the electronic fishing float 1 is floated on the water surface. [84] When the fish's bite starts, the body float 40 is positioned between the first sensor 51 and the second sensor 52 or between the second sensor 52 and the third sensor 53, and at this time, the body float 40 is moved reciprocally between the first sensor 51 and the third sensor 53 at the state where the fish is biting. [85] If the body float 40 moves, the signal moving between the first sensor 51 and the third sensor 53 is sent to the radio receiver 2 through the micro control unit and the radio transmitter mounted on the PCB 80. [86] At this time, the camera 70 is operated by the angler to check the fish's state, and while checking, the angler is ready to pull the fishing rod from the water. [87] If the fish bites the bait, the separable circular magnet 43 positioned between the first sensor 51 and the third sensor 53 momentarily passes the third sensor 53 and moves to the fourth sensor 54. [88] At this time, the fish's bite is checked by the angler, and the fishing rod is pulled from the water by the angler to get the fish. [89] Since the fish's state is recognized through the image in the above-mentioned process, the separable circular magnet 43 positioned on the lower end periphery of the body float 40 is placed at the same line as the third sensor 53 in the space portion 11a of the body 10, and at the same time, the fishing rod is pulled from the water by an angler in accordance with the signal sent from the raid transmitter through the micro control unit of the PCB 80 and the antenna 21 of the upper cap 20.

[90] If the power of the battery is all consumed during the use of the electronic fishing float 1 according to the present invention, the signal indicating that the power of the battery is being all consumed is sent to the radio transmitter.

[91] After the signal is checked by the angler, the fishing rod is pulled from the water and the electronic fishing float 1 is separated from the fishing rod.

[92] At this state, the battery-charging cap 23 is opened from the upper cap 20, and a plug is pushed inside the charging hole 20b such that electricity is recharged through an adapter.

[93] The number of fishes caught when the fishing is conducted by using the electronic fishing float 1 according to the present invention is larger than that when it is conducted by using conventional electronic fishing floats, thereby providing happy fishing to the angler.

[94] If the electronic fishing float 1 is pulled from the water after completing the fishing, the electrode switch 14 mounted in the space portion 1 Ia of the wing part 11 of one side of the body 10 is not operated to automatically cut the power of the battery, thereby preventing unnecessary consumption of power of the battery.

[95] While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention. Industrial Applicability

[96] As mentioned above, the multi-function electronic fishing float according to the present invention provides happy fishing and exciting leisure activities to an angler, instead of boring fishing, and allows the state in the water and the kind of fishes to be checked through the camera mounted in the lower cap, such that the fishing can be enjoyed in a scientific method using an information technology, which is very useful in the fishing industrial field.
