Description

A FISHING WEIGHT

Technical Field

[1] The present disclosure relates to a fishing weight.

Background Art

[2] Generally, a fishing preparation is made by connecting a fishing weight locating a fishing hook at a suitable position in suit with the buoyancy of a fishing float to a fishing line after the fish hook and the fishing float are selected in consideration of a fishing place, a target fish, etc.

[3] The fishing weight is generally penetrated in a vertical direction by the fishing line so as to move along the fishing line. In lure fishing, the fishing hook and the fishing weigh may be together connected to the fishing line in a bundle.

[4] However, the general fishing weight may be stuck in crannies of rocks or pebbles because the fishing weight lies in a horizontal direction upon touching the rocks or the pebbles of the bottom.

[5] In this case, the fishing weight may be separated from the fishing line when the fishing line is forcibly pulled up. This more frequently happens to beginners unfamiliar with fishing.

[6] Moreover, the fishing weight is generally made of lead having a high specific gravity so as to rapidly sink to a depth in the water. Accordingly, there may be a serious problem that causes serious environmental pollution, when the fishing weights frequently separated from the fishing line are left unrecovered. Disclosure of Invention Technical Problem

[7] Embodiments provide a fishing weight for maintaining an erect posture by including a weight part at a lower part of a main body and a buoyant part having a relatively low specific gravity at an upper part of the main body, and for controlling the buoyancy and the weight of the fishing weight by selectively adding a detachable member to the main body.

Technical Solution

[8] In one embodiment, a fishing weight includes: a weight part for forming a lower shape of the fishing weight and formed of a material having a specific gravity greater than water; a buoyant part selectively separably coupled to the upper side of the weight part and formed of a material having a specific gravity lower than that of the weight part; fixing means provided on an upper side of the buoyant part to fix the buoyant part to a fishing line; a buoyancy control member selectively coupled to the weight part and the buoyant part therebetween and formed of the same material as the buoyant part; and a weight control member selectively coupled to the weight part and the buoyant part therebetween and formed of the same material as the weight part.

[9] In another embodiment, a fishing weight includes: a main body having a barrel shape and selectively divided into an upper portion and a lower portion; a weight member accommodated in the inside of the main body and formed of a material having a specific gravity greater than water; an extending member opened upwardly and downwardly and selectively coupled to the upper portion and the lower portion of the main body therebetween to extend a length of the main body; and fixing means provided on an upper end of the main body and connected to a fishing line.

[10] In further another embodiment, a fishing weight includes: a main body capable of being selectively separated into an upper portion and a lower portion; a buoyancy control member selectively coupled to the upper portion and the lower portion of the main body therebetween, formed of a material having a specific gravity lower than water and having a barrel shape; a weight member selectively accommodated in the buoyancy control member and formed of a material having a specific gravity greater than water; and fixing means provided on an upper end of the main body to fix the main body to a fishing line.

[11] In still further another embodiment, a fishing weight includes: a buoyant part having a circular or oval cross-sectional shape and formed of a material having a specific gravity greater than water; fixing means provide on an upper end of the buoyant part to fix the buoyant part to a fishing line; and a weight part having a rod shape, selectively coupled to a lower side of the buoyant part, and formed of a material having a specific gravity greater than the buoyant part.

[12] The details of one or more embodiments are set forth in the accompanying drawings and the description below. Other features will be apparent from the description and drawings, and from the claims.

Advantageous Effects

[13] As described above, a fishing weight according to an embodiment necessarily maintains an erect posture in the water because an upper portion of the fishing weight is fixed at a fishing line and a lower portion of the fishing weight has a specific gravity greater than the lower portion of the fishing weight.

[14] Although the fishing line is pulled up, the fishing weight is prevented from being stuck in crannies of rocks or pebbles because the fishing weight maintains the erect or similar posture.

[15] In this way, since the fishing weight can be prevented from being separated from the fishing line, inconveniences and rising costs due to a replacement of the fishing weight is expected to be solved. [16] Contamination of water arising from the lead fishing weight is expected to be prevented.

[17] Furthermore, since the buoyancy and the weight of the fishing weight is controllable by simply adding a buoyancy control member, a weight control member or a weight member to the fishing weight, convenience in using the fishing weight can be improved. Additional cost and environmental contamination can be prevented because the fishing weight is constantly used for a long time with the buoyancy and the weight of the fishing weight changed.

Best Mode for Carrying Out the Invention [25] Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. However, the scope of the present disclosure will not be limited to the embodiments proposed herein.

Rather, additions, deletions and modifications of other components will easily propose other embodiments within the present disclosure or other inventions. [26] Fig. 1 is a view illustrating a using state of a fishing weight according to an embodiment. [27] Referring to Fig. 1, a fishing hook 20 is connected to an end of a fishing line 10. A fishing float 30 is connected to one side of the fishing line 10 apart from the fishing hook 20. [28] Generally, the fishing line 10 includes a fishing line and a snell. Two fold yarn, nylon and monofilament are wired to form the fishing line 10. The fishing hook 20 has various sizes and shapes according to target fishes, and is connected to an end of the fishing line 10. The fishing float 30 floats by buoyancy while a fishing weight 1 and bait lie on the bottom, and delivers a bite of fish through the fishing line 10.

[29] The fishing weight 1 is connected to one side of the fishing line between the fishing hook 20 and the fishing float 30. The fishing weight 1 serves to submerge the fishing hook 200 at a desired place in the water, and therefore, is formed of relatively heavy material.

[30] The fishing weight 1 may have such a proper weight according to a fishing place and a target fish as to match the buoyancy of the fishing float 30.

[31] With reference to Figs 2 and 3, a fishing weight will be more fully described as follows.

[32] Fig. 2 is an exploded view illustrating a configuration of a fishing weight according to a first embodiment. Fig. 3 is a perspective view illustrating a constructing means of a fishing weight according to another embodiment.

[33] Referring to Figs 2 and 3, a main body 100 of the fishing weight 1 has a round bar shape having a vertical length longer than the horizontal length, and has a round peripheral surface for a low resistance to fluid. The main body 100 is divided into an upper portion and a lower portion which correspond to a weight part 110 and a buoyant part 120.

[34] The weight part 110 forms a lower shape of the main body 100, which may be formed of material (e.g., metal such as lead, stone, etc.) having a specific gravity greater than water. A coupling opening 112 is formed at the upper side of the weight part 110 so as to be coupled to the buoyant part 120 as described below. The top surface of the weight part 110 is inwardly recessed to form the coupling opening 112. A thread is formed on inner peripheral surface of the coupling opening 112 to engage with a thread on a coupling end 122 as described below.

[35] The buoyant part 120 forms an upper shape of the main body 100, which forms an entire shape of the main body by being coupled to the weight part 110. The buoyant part 120 is formed of materials having a specific gravity less than the specific gravity of the weight part 110 so as to maintain the erect posture of the fishing weight

[36] That is, the buoyant part 120 is formed of materials (e.g., Styrofoam, sponge, wood, etc.) having a specific gravity lower than the specific gravity of the weight part 110, so that the weight part 110 and the buoyant part 120 can direct toward the bottom and the top, respectively.

[37] A coupling end 122 is formed at the lower side of the buoyant part 120 to engage with the coupling opening 112. The coupling end 122 is protruded from the un- dersurface of the buoyant part 120, and has such a matching shape as to be inserted into the coupling opening 112. [38] A thread matching the thread on the inner peripheral surface of the coupling opening 112 is formed on the peripheral surface of the coupling end 122, so that the coupling end 122 can engage with the coupling opening 112 by rotating the buoyant part 120.

[39] When the coupling end 122 fully engages with the coupling opening 112, the main body has a round shape as a whole. The weight part 110 and the buoyant part 120 can be separated from each other if needed.

[40] For example, a buoyancy control member 130 or a weight control member 140 may be added between the weight part 110 and the buoyant part 120 to control the buoyancy or the weight of the fishing weight 1.

[41] More specifically, the buoyancy control member 130 is formed of the same material as the buoyant part 120 so as to increase the buoyancy of the fishing weight 1, and is coupled to the lower side of the buoyant part 120.

[42] Accordingly, a coupling opening 132 having the same shape as the shape of the coupling opening 112 is formed at the upper side of the buoyancy control member 130. In addition, a control member coupling end 134 matching the coupling end 122 is formed at the lower side of the buoyancy control member 130.

[43] When the buoyancy control member 130 is coupled to the fishing weight 1, the coupling end 122 of the buoyant part 120 is coupled to the control member coupling opening 132 of the buoyancy control member 130, the control member coupling end 134 of the buoyancy control member 130 is coupled to the coupling opening 112 of the weight part 110.

[44] In this case, a shape of the buoyancy control member 130 may have such a cylindrical shape as to form the center part of the main body 100.

[45] On the other hand, the weight control member 140 adds a weight to the fishing weight 1, allowing the fishing weight 1 to sink to a greater depth. The weight control member 140 is formed of the same material as the weight part 110. Similarly, a control member coupling opening 142 and a control member coupling end 144 are formed at the upper side and the lower side of the weight control member 140, respectively.

[46] The weight control member 140 is coupled to the lower side of the buoyant part 120 when requiring to control only the weight of the fishing weight 1, and is coupled to lower side of the buoyancy control member 130 when requiring to control the weight as well as the buoyancy of the fishing weight 1.

[47] The weight control member 140 has the same cylindrical shape as the buoyancy control member 130, so that the fishing weight 1 can maintain an uniform shape as a whole when the weight control member 140 is coupled to the buoyant part 120 and the weight part 110 as well as when the weight control member 140 is coupled to the buoyancy control member 130. [48] Furthermore, one or more buoyancy control members 130 or weight control members 140 may be coupled to fishing weight 1, and may have a variety of heights to minutely control the buoyancy and the weight of the fishing weight 1.

[49] A fixing means 150 is mounted onto the buoyant part 120. The fixing means 150 serves to allow the main body 100 to be connected to the fishing line 10. The fixing means 150 has a ring shape, and is freely rotatable on the upper end of the buoyant part 120.

[50] For this end, the fixing means 150 include a coupling ring 152 and an installation pin 154. The coupling ring 152 has a ring shape, and is penetrated by the fishing line 10. The installation pin 154 penetrates the coupling ring 152, which is downwardly extended and coupled to the upper end of the buoyant part 120.

[51] Accordingly, the coupling ring 152 is rotatable around the installation pin 154, so that the main body 100, that is, the buoyant part 120 and the weight part 110 can rotate when the fishing line 10 penetrates the coupling ring 152. Subsequently, the fishing weight 1 may not be tangled with the fishing line 10.

[52] As illustrated in Fig. 1, a fixture 40 is further provided at the both of the fishing line

10 to prevent the fishing weight 1 from moving along the fishing line 10 upwardly and downwardly. The fixture 40 may be formed with a bead or a knot.

[53] Although not illustrated in Figures, a plurality of fixing means 150 may be formed at the buoyant part 120 or the weight part 110. In this case, the fishing line 10 penetrates all the plurality of the fixing means 150, so that the fishing weight 1 may not be tangled with the fishing line 10.

[54] Hereinafter, an application of the fishing weight having a configuration as described above according to a first embodiment will be described with reference to Figs 1 and 2.

[55] A user connects a fishing weight 1 to a fishing line 10 prepared with a fishing hook

20 and a fishing float 30. The fishing weight 1 is selected in consideration of a buoyancy of the fishing float 30 so as to place the fishing hook 20 at a suitable depth in the water.

[56] The coupling ring 152 of the fixing means 150 is penetrated by the fishing line 10, so that the fishing weight 1 may be place at one side of the fishing line 10 between the fishing hook 20 and the fishing float 30. In addition, the fixture 40 such as a bead or a knot installed at the both side of the fixing means 150 prevents the fishing weight 1 from floating along the fishing line 10.

[57] The fixing means 150 is configured to be rotatable while coupled to the buoyant part 120, so that the fishing weight 1 is freely rotatable while coupled to the fishing line 10. Subsequently, the fishing weight 1 can be prevented from being entangled by the fishing line 10.

[58] In addition, when a user use a fishing preparation prepared by connecting the fishing weight 1 to the fishing line 10, the fishing weight 1 sinks to a predetermined depth in the water to place the fishing hook 20 at a desired place in the water through an equilibrium state between the weight of the fishing weight 1 and the buoyancy of the fishing float 30.

[59] In the case, while the fishing weight 1 is fixed to the fishing line 10 by the fixing means 150 on the upper end of the fishing weight 1, the weight part 110 having a higher specific gravity is necessarily downwardly directed so that the fishing weight 1 may be in an erect state.

[60] In this way, the fishing weight 1 can maintain the erect state even when the fishing weight 1 touches the bottom. Subsequently, the fishing weight 1 can be effectively prevented from being stuck in crannies of rocks or pebbles because the fishing weight 1 maintains the erect or similar state during pulling up of the fishing line 10.

[61] Furthermore, the fishing weight 1 is situated on a low possibility of being stuck in crannies of rocks and is prevented from being fluctuated by the water flow owing to its features of a vertically long body and a round peripheral surface.

[62] Meanwhile, the buoyancy and/or the weight of the fishing weight 1 are controllable according to a fishing environment and a target fish. Hereinafter, a process of controlling the buoyancy and/or the weight of the fishing weight 1 will be fully described with reference to Fig. 2. First, the main body 100 assembled through a threaded structure is separated into the buoyant part 120 and the weight part 110 by rotating the buoyant part 120 or the weight part 110.

[63] And then, for a control of the buoyancy of the fishing weight 10, the buoyancy control member 130 is interposed between the buoyant part 120 and the weight part 110. That is, after the coupling end 122 of the buoyant part 120 is threaded into the control member coupling opening 132 of the buoyancy control member 130, the control member coupling end 134 of the buoyancy control member 130 is threaded into the coupling opening 112 of the weight part 110.

[64] Since the buoyancy control member 130 is formed of the same material as the buoyant part 120, a volume of a part having a specific gravity lower than the weight part 110 increases to enhance the buoyancy of the fishing weight as a whole.

[65] For a control of the weight of the fishing weight 10, the weight control member 140 is interposed between the buoyant part 120 and the weight part 110. That is, after the coupling end 122 of the buoyant part 120 is threaded into the control member coupling opening 142 of the weight control member 140, the control member coupling end 144 of the weight control member 140 is threaded into the coupling opening 112 of the weight part 110.

[66] Since the weight control member 140 is formed of the same material as the weight part 110, a volume of a part having a specific gravity greater than the buoyant part 120 increases to enhance the weight of the fishing weight as a whole.

[67] For a simultaneous control of the buoyancy and the weight of the fishing weight 1, the both buoyancy control member 130 and the weight control member 140 are interposed between the buoyant part 120 and the weight part 110 in the same way as described above.

[68] Furthermore, a plurality of the buoyancy control member 130 and/or the weight control member 140 may be interposed between the buoyant part 120 and the weight part 110. Detail description of this application will be omitted because the plurality of the buoyancy control member 130 and/or the weight control member 140 are coupled in the same way as describe above.

[69] Various variations of the fishing weight 1 according to the first embodiment are possible. Hereinafter, a fishing weight 1 according to a second embodiment will be described with reference to Fig.2.

[70] Since the fishing weight 1 has a similar configuration with the configuration of the fishing weight 1 according to the first embodiment. Like parts are denoted by like reference numbers. Detail description of the like parts will be omitted.

[71] Referring to Fig. 4, a main body 200 of the fishing weight 1 has a cylindrical shape having a vertical length longer than the horizontal length. The main body 200 is divided into an upper portion and a lower portion which correspond to a weight part 210 and a buoyant part 220.

[72] The weight part 210 has a hollow space inside. The space receives a weight member

260, is upwardly opened. A coupling opening 212 having a threaded shape is provided at the upper end of the weight part 210 to be coupled to a coupling end 222 having a treaded shape at the lower end of the buoyant part 220.

[73] The weight part 210 may be formed of materials having a specific gravity greater than water to allow the fishing weight 1 to be erect by itself. However, the weight part 210 may be formed of the same material as the buoyant part 220 to enhance uniformity and coupling characteristic with the buoyant part 220.

[74] A fixing means 250 is rotatably mounted onto the upper end of the buoyant part

220. The fixing means 250 is penetrated by a fishing line 10.

[75] A buoyancy control member 230 like that of the first embodiment may be further interposed between the buoyant part 220 and the weight part 210. The buoyancy control member 230 is formed of materials having a specific gravity lower than water or formed of the same material as the buoyant part 220. Various sizes and numbers of the buoyancy control members 230 may be adoptable according to a user's choice. In addition, when the coupling between the buoyancy control member 230 and the buoyant part 220 and/or the weight part 210 employs a coupling way by a threaded structure as describe above, the buoyancy control member 230 and the weight control member 240 further require a control member coupling end 232 and 242, and a control member coupling end 234 and 244, respectively.

[76] A weight member 260 having a predetermined weight is accommodated in the hollow space inside the weight part 210. The weight member 260 is formed of material such as lead having a great specific gravity, and has a spherical or a block shape having a predetermined volume so as to be filled into the hollow space.

[77] One or more weight members 260 may be accommodated in the hollow space of the weight part 210. A user may use various numbers of the weight members 260 to control the weight of the fishing weight 1 according to the use s choice. The weight members 260 may have various size and weights, and be formed of materials having different specific gravities. In this way, the user may make the fishing weight 1 having various weights by mixing the weight members 260 in the hollow space with a predetermined volume.

[78] Accordingly, the user may control the entire weight of the fishing weight 1, and freely determine a location of the fishing hook 20 according to the buoyancy of the fishing float 30 or the target fish.

[79] Various variations of the fishing weight 1 according to an embodiment are possible besides the first and second embodiments. Hereinafter, a third embodiment will be described as follows with reference to Fig.5.

[80] Referring to Fig. 5, a main body 300 of the fishing weight 1 has a cylindrical shape having a vertical length longer than the horizontal length. The main body 300 is divided into an upper portion 320 and a lower portion 310 at the substantially central part.

[81] A hollow space is formed inside the main body 300. The upper portion 320 is downwardly opened, and the lower portion 310 is upwardly opened, so that the main body 300 may have an entirely hollow space inside.

[82] The upper and lower portions 320 and 310 of the main body 300 may be formed of the same materials as the buoyant part (120 in Fig. 2) and the weight part (110 in Fig.2) in the first embodiment, respectively. When needed, the main body 300 may be entirely formed of the same material as the buoyant part (120 in Fig. 2) or the weight part (110 in Fig.2) in the first embodiment.

[83] A weight member 360 as described in the second embodiment is accommodated in the hollow space inside the main body 300. A plurality of the weight members 350 may be accommodated according to a user's choice. Also, the fishing weight 1 may have various weights according to mixtures of various weight members 360.

[84] An extending member 370 is interposed between the upper portion 320 and the lower portion 310. The extending member 370 has a cylindrical shape opened upwardly and downwardly. The extending member 370 communicates between the upper portion 320 and the lower portion 310 to increase an entire volume of the hollow space inside the main body 300. In this way, it is possible to control the amount of the weight members 360.

[85] That is, when the extending member 370 is not coupled to the main body 300, the hollow space may be insufficient to control the entire weight of the fishing weight 1. Accordingly, the extending member 370 may be interposed between the upper portion 320 and the lower portion 310 to increase the hollow space for accommodating the weight member 360.

[86] A plurality of the extending members 370 may be sequentially connected to each other to increase an entire length of the main body 300 as well as to control the hollow space inside the main body 300.

[87] When the plurality of the extending members 370 are coupled to the main body

100, the extending members 370 may includes the buoyancy control member 330 formed of the same material as the buoyant part (120 in Fig. 2) and the weight control member 340 formed of the same material as the weight part (110 in Fig. 2). Also, the extending member 300 is formed of the same material as the buoyant part (120 in Fig. 2) or the weight part (110 in Fig. 2).

[88] Meanwhile, the upper portion 320 and the lower portion 310 of the main body 300 include a coupling end 322 and a coupling opening 312 with a threaded structure matching each other as described in the second embodiment, respectively. The extending members 370 include control member coupling openings 334 and 344 and control member coupling ends 333 and 342, respectively. The upper portion 320 and lower portion 310 of the main body 300 may be coupled together by using an interference fit method or an adhesive means such as an adhesive tape or an adhesive if needed.

[89] When the extending member 370 is coupled to the main body 300, the main body

300 may is formed in cylindrical shape. The peripheral surfaces of the extending member and the main body 300 are evenly connected to each other without any protrusion or recess to give a sense of unity as a whole.

[90] The upper end of the main body is provided with a fixing means 350 as described above, through which the fishing line 10 passes.

[91] Various variations of the fishing weight 1 according to the present are possible besides the first through third embodiments as described above. Hereinafter, a fourth embodiment will be described as follows with reference to Fig.6.

[92] Referring to Fig. 6, the main body 400 includes a buoyant part 420 having a specific gravity lower than water, and a weight part 410 having a specific gravity greater than that of the buoyant part 420 as described in the first embodiment. The buoyant part 420 and the weight part 410 includes a coupling end 422 and a coupling opening 412, re- spectively, to be selectively separably coupled to each other.

[93] A buoyancy control member 430 and a weight control member 440 are separably coupled to the buoyant part 420 and the weight part 410, respectively.

[94] The buoyancy control member 430 is formed of the same material as that of the buoyant part 420, and has a cylindrical shape matching a shape of the main body 400. The buoyancy control member 430 is upwardly and downwardly opened to have a hollow space inside.

[95] The weight control member 440 is formed of the same material as that of the buoyant part 410, and has a cylindrical shape matching a shape of the main body 400. The buoyancy control member 440 is upwardly and downwardly opened to have a hollow space inside.

[96] Thus, the buoyancy control member 430 and the weight control member 440 have the hollow spaces, providing an entire space to the main body 400 by being respectively coupled to the main body 400.

[97] When a plurality of the buoyancy control members 430 and/or the weight members

440 are coupled to the main body 400, the hollow spaces of the buoyancy control members and/or the weight members 440 are communicated with each other to form the entire space in the main body 400.

[98] Accordingly, the hollow space is formed inside the main body 400, that is, the buoyancy control member 430 and the weight control member 440 to accommodate a weight member 460 when the buoyancy control member 430 and/or the weight control member 440 are coupled to the buoyant part 420 and/or the weight part 410 of the main body 400, respectively.

[99] A user may control an entire weight of the fishing weight 1 by filling the hollow space formed by the buoyancy control member 430 or the weight control member 440 with at least one of the weight members 460.

[100] For example, the user may increase the buoyancy of the fishing weight 1 by additionally interposing the buoyancy control member 430 between the buoyant part 420 and the weight part 410. Also, the user may increase the weight of the fishing weight 1 by additionally interposing the weight control member 440 between the buoyant part 420 and the weight part 410 or filling the hollow space formed by the buoyancy control member 430 or the weight control member 440 with the weight member 460.

[101] As describe above, a coupling end 422 and a coupling opening 412 are formed at the buoyant part 420 and the weight part 410 of the main body 400, respectively. Also, the control member coupling ends 432 and 442 and the control member coupling opening 434 and 444 are formed at the buoyancy control member 430 and the weight control member 440, respectively. Therefore, the main body 400, the buoyancy control member 430 and the weight control member 440 may be coupled to each other by a threaded structure as describe above.

[102] A fixing means 450 is mounted onto the upper end of the main body 400 to allow the fishing line 10 to pass through the fixing means 450.

[103] Various variations of the fishing weight 1 according to the present are possible besides the first through fourth embodiments as described above. Hereinafter, a fifth embodiment will be described as follows with reference to Fig.7.

[104] Referring to Fig. 7, the fishing weight 1 includes a buoyant part 520 and a weight part 510.

[105] The buoyant part 520 forms an upper of the fishing weight 1. The buoyant part 520 has a substantially spherical or an oval shape having a specific gravity lower than water. Accordingly, the buoyant part 520 is formed of light material (e.g., Styrofoam, sponge, wood, etc.) which may float on the water.

[106] A fixing means 550 is formed on the upper end of the buoyant part 520. The fixing means 550 is configured to allow the fishing weight 1 to be connected to the fishing line 10, so that the fishing weight 1 is freely rotatable while connected to the fishing line 10.

[107] Meanwhile, a coupling opening 522 is formed at the lower side of the buoyant part

520 to engage with a weight part 510 as described below. A plurality of the coupling openings 522 are radially formed around the center of the lower side of the buoyant part 520. A thread is formed at the inner peripheral surface of the coupling opening 522 to engage with a coupling end 522 of a weight part 510.

[108] The weight part 510 is formed of a material (e.g., metal such as lead) to control the weight of the fishing weight 1, and has a rod shape extending upwardly and downwardly.

[109] The weight part 510 may have various lengths according to its weights. A coupling end 512 is formed at the upper end of the weight part 510 and serves to couple the weight part 510 to the buoyant part 520. The coupling end 512 is formed at the peripheral surface of the upper end of the weight part 510, and has a thread matching the coupling opening 522.

[110] A plurality of the weight parts 510 are coupled to a plurality of the coupling openings 522 formed at the lower side of the buoyant part 520. The weight part 510 may have a coupling end 512 at one side, and a coupling opening 522 at the other side to be successively coupled to each other.

[I l l] A plurality of the weight parts 510 may be coupled to the buoyant part 520. The plurality of the weight parts 510 may be coupled to the buoyant part 520 in consideration of the entire balance. The plurality of the weight parts 510 may be extended to the same directions as the edges extending from the vertex of the triangular pyramid. In this case, the center of gravity of the fishing weight 1 is stable, and is stably seated on the bottom of the water.

[112] That is, when the plurality of the weight parts 510 are coupled to the buoyant part

520, the plurality of the weight parts 510 may be outwardly tilted to maintain a stable posture on touching the bottom or rocks.

[113] In the configuration as describe above, the buoyant part 520 is coupled to the weight part 510 to establish the weight of the fishing weight 1. The number of the weight part 510 may be determined in consideration of the buoyancy of the fishing float 30 and a target fish.

[114] The coupling end 512 of the weight part 510 is coupled to the coupling opening 522 of the buoyant part 520 by rotating the weight part 510 in a screw coupling way.

[115] When one of the weight parts 510 is coupled to the buoyant part 520, the weight part 510 is coupled to the coupling opening 522 at the center of the lower side of the buoyant part 520. When the plurality of the weight parts 510 are couple to the buoyant part 520, the plurality of the weight parts 510 are symmetrically couple to the coupling openings 522 to balance the weight of the fishing weight 1 as a whole.

[116] The fishing line 10 passes through a fixing means 550, so that the fishing weight 1 is placed at one side between the fishing hook 20 and the fishing float 30.

[117] When the fishing line 10 according to the above preparation is thrown into the water, the fishing weight 1 and the fishing hook 20 sinks in the water to stop at a depth of the water where the equilibrium between the buoyancy and the weight is achieved or touch the bottom of the water.

[118] In this case, a weight part 510 having a relatively greater specific gravity and a relatively longer length is placed at the center of the lower side of the buoyant part 520. Also, the upper end of the fishing weight 1 is connected to the fishing line 10 through the fixing means 550. Accordingly, the center of gravity of the fishing weight 1 is naturally placed at a lower side thereof, so that the fishing weight 1 may take an erect posture.

[119] Although embodiments have been described with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure. More particularly, various variations and modifications are possible in the component parts and/or arrangements of the subject combination arrangement within the scope of the disclosure, the drawings and the appended claims. In addition to variations and modifications in the component parts and/or arrangements, alternative uses will also be apparent to those skilled in the art. Industrial Applicability A fishing weight according to an embodiment maintain an erect posture to prevent a loss due to a sticking of the fishing weight because a weight part of the fishing weight is located at a lower side thereof. Furthermore, convenience in using the fishing weight can be improved to enhance the industrial applicability by freely controlling the buoyancy and weight of the fishing weight by using a buoyancy control member, a weight control member and a weight member.
