Description

[Technical Field]

[0001] The present invention relates to a fishing sinker. [Background technology]

[0002] For example, a sheet-like fishing weight may be attached to a lure to make the lure sink at a preferred sinking speed or swim with a desired balance.

[0003] For example, one proposed item to be attached to a lure is "an adjustment sinker that is detachably attached to the head of a fishing lure body that is roughly spindle-shaped and has a fishing hook at the rear, the head being on the side opposite the hook, the fishing lure body having a line eye that protrudes upward from near the space between the eyes at the head, and a sinker portion that protrudes downward near the eyes, the adjustment sinker having a long hole that is inserted across the line eye and a notch for allowing the sinker portion to escape when attaching or detaching, the longitudinal direction of the long hole being aligned with the longitudinal direction of the fishing lure body" (see Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3191215 Summary of the Invention [Problem to be solved by the invention]

[0005] The weight of the adjustment weight attached to the head of the lure cannot be adjusted, so it is necessary to prepare several types with different weights and use them accordingly. Also, depending on the shape and size of the head of the lure, the adjustment weight may not be able to be attached.

[0006] The sheet-like fishing weights are attached to the surface of a lure and can therefore be used with a wide variety of lures. However, like the adjustment weights, the weight of the weight itself cannot be easily adjusted, so multiple types with different weights are often prepared and used separately.

[0007] That is, although the sheet-shaped fishing weight can be cut to any weight at the fishing site, it takes time and effort to calculate and cut the exact weight on the spot.

[0008] Furthermore, because the ideal weight of a fishing sinker depends on the current of the river or seawater at the location, it is necessary to adjust it by attaching it to the lure and submerging it. However, cutting the weight while it is still attached to the lure can scratch the lure. Furthermore, since the lure is wet and slippery, it can lead to injury. On the other hand, if you repeatedly attach and remove the weight, such as by peeling it off and cutting it, dirt and water will get on the adhesive surface, making the weight more likely to come off while using the lure.

[0009] The present invention is intended to solve at least one of the above problems, and has an object to provide a fishing weight whose weight can be easily adjusted at the fishing spot. [Means for solving the problem]

[0010] One aspect of the present invention that solves the above problem is a fishing sinker that includes a sheet-like main body that is formed symmetrically about a center line, the main body having a base that straddles the center line and an adjustment portion, the adjustment portion being configured symmetrically about the center line on both sides of the base, and when the line-symmetric adjustment portion is removed, the weight of the main body is reduced by a specified amount while maintaining the line-symmetric shape.

[0011] The body may have a notched relief portion straddling the centerline.

[0012] The main body may have a pair of the adjustment portions.

[0013] The main body may have the adjustment portion spanning the center line.

[0014] The body may be capable of losing weight in fixed increments.

[0015] It may also be provided with an adhesive portion for surface-attaching to a lure. [Effects of the Invention]

[0016] According to the present invention, a fishing weight can be provided that allows the weight to be easily adjusted at the fishing spot.

[0017] Problems, configurations, and effects other than those described above will become apparent from the following description of the embodiments. [Brief explanation of the drawings]

[0019] Hereinafter, examples of embodiments of the present invention will be described with reference to the drawings. Note that components common to the following embodiments will be assigned the same reference numerals as those previously mentioned, and their description may be omitted. Furthermore, when referring to the shape, positional relationship, etc. of components, etc., it is understood that the reference numerals include those that are substantially similar or similar to the shape, etc., unless otherwise specified or when it is clearly considered otherwise in principle.

[0020] <Embodiment 1> 1A and 1B are external views illustrating an example of a fishing sinker according to embodiment 1, with (a) a plan view and (b) a front view. In the drawing, X indicates the left-right direction (width direction), Y indicates the up-down direction (thickness direction), and Z indicates the length direction (front-rear direction) (the same applies to the following drawings).

[0021] The fishing sinker 1 of the present application (hereinafter simply referred to as "sinker 1") is used to adjust the weight of fishing equipment, for example, the weight of a lure. A lure generally has a ring-shaped part called an eye, which has a part called a line eye for tying a line (fishing line) to it, and a part called a hook eye for attaching a hook.

[0022] 2 is a diagram showing an example of a lure. As shown in the example, the lure L has, for example, a line eye L1 at the front end (front end of the head), one or more hook eyes L2 at the lower end (lower end of the body), and a hook eye L3 at the rear end. In the example shown, a fishing hook (hook) J is attached to the hook eye L2 at the lower end, but the hook J may also be attached to the hook eye L3 at the rear end, or hooks J may also be attached to all of the hook eyes. The weight 1 is attached to the lure L so that its longitudinal direction (length direction) is aligned with the longitudinal direction of the lure L.

[0023] The sinker 1 includes at least a main body 2. The main body 2 is a part that functions as a weight to increase the weight of the fishing equipment, in this case, the lure L. The main body 2 is sheet-shaped (plate-shaped) that is thin relative to its plane area, and has approximately flat upper and lower surfaces. The main body 2 has a thickness of, for example, 0.3 mm to 1 mm.

[0024] The main body 2 is preferably attached to the surface of the lure L using, but not limited to, an adhesive tape or a glue. The adhesive tape or glue used is preferably water-resistant, but not limited to, the main body 2 may be fixed by wrapping it around the lure L, or may be fixed by inserting or stuffing it into a receiving portion (such as a hole or groove) of the lure L.

[0025] More preferably, the weight 1 includes, in addition to the main body 2, an adhesive portion 5 for planarly attaching the weight to the surface of the lure L. As an example, the adhesive portion 5 is attached to the entire underside of the main body 2. The adhesive portion 5 is, for example, a double-sided tape, which is peeled off from a release paper (not shown) when attached to the lure L. The configuration of the main body 2 will be described in detail below.

[0026] The main body 2 has a shape that is line-symmetrical with respect to the center line A. By configuring it in this manner, the main body 2 can be attached symmetrically to the lure L, and the weight can be adjusted without changing the left-right balance of the lure L. As an example, the main body 2 has a generally rectangular shape in a plan view.

[0027] As an example, the main body 2 has a notched relief portion 21 that straddles the center line A. The relief portion 21 has a shape that is cut from the outer periphery along the center line A from one end to the other end in the longitudinal direction of the main body 2. Sheet-like fishing weights are often attached around the hook eye L2, and by providing the main body 2 with this relief portion 21, it is possible to attach it around the hook eye L2 while avoiding interference with it.

[0028] The main body 2 has, as components that function as a weight, a base portion 3 that straddles the center line A, and an adjustment portion 4. In this embodiment, the relief portion 21 is provided in the base portion 3.

[0029] The adjustment units 4 are configured symmetrically about the center line A on both the left and right sides of the base 3. The main body 2 in this embodiment has an even number of adjustment units 4, and the paired adjustment units 4 on the left and right sides are configured symmetrically about the center line A.

[0030] As an example, in the illustrated example, the main body 2 has three sets (pairs) of adjustment parts 4, for a total of six. Specifically, from the inside, on both the left and right sides of the base 3, there is one set of first adjustment parts 4a, one set of second adjustment parts 4b, and one set of third adjustment parts 4c. In the present application, the side closest to the center line A is defined as the inside, and the opposite side is defined as the outside. Here, the number of adjustment parts 4 is not particularly limited as long as it is an even number. As an example, the main body 2 has one to eight sets of adjustment parts 4.

[0031] By providing the main body 2 with the base portion 3 and the adjustment portion 4 in this way, when the line-symmetric adjustment portion 4 is removed, the weight is reduced by a specified amount while maintaining the line-symmetric shape.

[0032] FIG. 3 is a diagram for explaining an example of a main body and an example of adjusting the main body weight according to the first embodiment.

[0033] In the main body 2, a pair of first adjustment parts 4a are made of the same material, have line-symmetric shapes, and are the same weight. A pair of second adjustment parts 4b and a pair of third adjustment parts 4c are also made of the same material, have line-symmetric shapes, and are the same weight.

[0034] The first to third adjustment units 4a to 4c have different weights, as shown in Fig. 3, for example. The first to third adjustment units 4a to 4c are configured so that their widths and weights decrease sequentially from the inside to the outside. For example, the set of first adjustment units 4a weighs 0.7g (0.35g for each first adjustment unit 4a), the set of second adjustment units 4b weighs 0.5g (0.25g for each second adjustment unit 4b), and the set of third adjustment units 4c weighs 0.3g (0.15g for each third adjustment unit 4c).

[0035] To reduce the weight of the main body 2, a set of adjustment parts 4, arranged symmetrically from the outside, is removed. For example, in the main body 2 shown in FIG. 3(a), the outer set of third adjustment parts 4c is first removed. This reduces the volume of the main body 2 by 0.3 g, as shown in FIG. 3(b). Next, the outer set of second adjustment parts 4b is removed, as shown in FIG. 3(c). The volume of the main body 2 is reduced by 0.5 g, as shown in FIG. 3(c). Finally, the inner set of first adjustment parts 4a is removed, as shown in FIG. 3(d). This reduces the volume of the main body 2 by 0.7 g, as shown in FIG. 3(d), leaving only the base 3 as the only component. In this way, the weight of the main body 2 can be gradually reduced by a specified amount. For example, the main body 2 is attached to a lure L, and the weight is adjusted by peeling off the outer adjustment parts 4 one by one.

[0036] The outer set of third adjustment parts 4c and the outer set of second adjustment parts 4b of the main body 2 may be removed simultaneously, or all three sets of adjustment parts 4 may be removed simultaneously. After removing the outer set of third adjustment parts 4c of the main body 2, the outer set of second adjustment parts 4b and the outer set of first adjustment parts 4a of the main body 2 may be removed simultaneously. The main body 2 may be attached to the lure L, and then the inner set of symmetrical adjustment parts may be removed first; however, in this case, water resistance increases and the main body 2 may be easily peeled off.

[0037] In this way, the weight of the main body 2 can be reduced by a specified amount by removing the line-symmetric adjustment portion from the outside. This allows the weight of the main body 2 itself to be adjusted at the fishing spot, and the lure L can be easily adjusted to a desired weight without having to carry multiple types of weights. In addition, since the weight of the main body 2 is easy to grasp, there is no need to repeatedly stick and peel it off, and the adhesive strength of the adhesive tape or adhesive is not easily reduced. Furthermore, since the remaining portion of the main body 2 after removing the adjustment portion can maintain a line-symmetric shape, the weight of the lure L can be adjusted without changing the left-right balance of the lure L.

[0038] As an example, any two or more sets of the main body 2 have the same width and weight. For example, as shown in FIG. 1, the first adjustment section 4a to the third adjustment section 4c all have the same width and weight. For example, all of the adjustment sections in one set weigh 0.5 g (0.25 g for each adjustment section). By configuring the main body 2 in this way, the weight can be reduced by a fixed amount, in this example, by 0.5 g.

[0039] The base portion 3 is not particularly limited, but in this example, it is preferably configured to have a weight of, for example, 0.5 g, similar to the set of adjustment portions 4.

[0040] In the main body 2, as one example, adjacent components are separated by slits. Preferably, the width of the slit is approximately zero, and the left and right side surfaces of adjacent components are at least partially in contact with each other. In the main body 2, as one example, each component including the base 3 and each adjustment unit 4 is formed by cutting slits in a single sheet material (plate material).

[0041] The sheet material used for the main body 2 is, for example, lead, but other materials with a high specific gravity suitable for use as a weight may also be used. The surface of the sheet material may be painted by carbon coating, printing, etc., from the viewpoint of preventing adhesion. From the viewpoint of environmental consideration, resin tungsten, bismuth alloy, etc. are preferable as the material for the sheet material.

[0042] 1(b), the main body 2 is divided so that the slits reach the underside of the sheet and each component is independent on both the upper and lower surfaces. In one example, the slits do not reach the underside of the sheet and each component is independent on the upper surface, but remains integrated on the lower surface without being separated.

[0043] Since the main body 2 is divided into its constituent parts by the slits, the weight can be easily adjusted by simply attaching it to the lure L and then peeling it off.

[0044] Weight 1 is manufactured by, but is not limited to, die cutting using a mold press as an example. As an example, first, a laminated material including a sheet material constituting main body 2, double-sided tape constituting adhesive portion 5, and release paper protecting the double-sided tape is cut all the way down to the release paper so that a slit is formed along with the outer periphery (outer shape) of weight 1. Then, relief portion 21 is cut out to form. As an example, such a laminated material is cut all the way down to the release paper so that the outer periphery of weight 1, the slit, and relief portion 21 are simultaneously formed. Note that weight 1 does not come apart because the double-sided tape elastically returns to its original shape after cutting, allowing the sides to stick together, and each component part can be independent while maintaining its overall integrity.

[0045] For example, the weight 1 is made by cutting the laminated material so that the outer periphery and the relief portion 21 of the weight 1 are all cut, and the slits are cut down to the double-sided tape or the sheet material. In this case, the user will need to manually separate the release paper or double-sided tape before use.

[0046] The weight 1 does not have to be manufactured such that the main body 2 is integral with the adhesive portion 5. For example, the weight 1 may be manufactured so that one or more weights 1 are arranged on a single piece of removable backing. This backing preferably has a lower adhesive strength than the double-sided tape that constitutes the adhesive portion 5, making it easy to remove from the weight 1. In this case, the user will peel the weight 1 from the backing and attach it to the lure L using another adhesive tape or adhesive, wrap it around the lure L, or insert it into the hole of the lure L.

[0047] Note that each component may be divided by printing dividing lines or marking grooves instead of slits. In this case, the user will be able to cut it with scissors or by hand.

[0048] <Modification 1 of Embodiment 1> 4A and 4B are external views for explaining an example of a fishing weight according to a first modification of the first embodiment, in which (a) is a plan view and (b) is a front view.

[0049] As an example, the main body 2 is configured to have a rounded shape. For example, as shown in the figure, the main body 2 has a circular shape in a plan view. The main body 2 may have an oval or elliptical shape, etc.

[0050] With this configuration, the main body 2 is less likely to peel off because it does not have sharp corners, and is less likely to peel off even when there is high water resistance or when it hits an obstacle in the water.

[0051] Depending on the location where the main body 2 is attached to the lure L, the main body 2 may not have the relief portion 21 as shown in the figure. The main body 2 may be marked with, for example, a dashed line by printing so that the center line A can be visually identified. This makes it easier to grasp the position of the center line A even when the main body 2 does not have the relief portion 21.

[0052] As shown in FIG. 4(b), in the main body 2 of this example, the slits do not reach the lower surface of the sheet, and each component is independent on the upper surface but remains integrated on the lower surface.

[0053] <Embodiment 2> 5A and 5B are external views for explaining an example of a fishing sinker according to embodiment 2, with (a) a plan view and (b) a front view. The sinker 1 of this embodiment differs from embodiment 1 above mainly in that the main body 2 has an adjustment part 4 that straddles the center line A. The following description will focus on the differences, and similar points will be omitted where appropriate.

[0054] Similar to the first embodiment, the weight 1 of this embodiment includes a sheet-like main body 2 formed symmetrically with respect to the center line A. Similar to the first embodiment, the main body 2 includes, as components that perform the function of the weight, a base 3 that straddles the center line A and an adjustment unit 4, and the adjustment unit 4 is formed symmetrically with respect to the center line A on both the left and right sides of the base 3.

[0055] On the other hand, in the first embodiment, the adjustment units 4 on both the left and right sides of the base 3 are independent of each other, whereas in the present embodiment, the adjustment units on both the left and right sides are connected to each other.

[0056] As an example, as shown in the figure, the adjustment unit 4 is configured in the shape of a square frame, and is configured in a shape that surrounds the base unit 3. In other words, the adjustment unit 4 is configured concentrically with the base unit 3.

[0057] By configuring the main body 2 in this manner, the weight 1 of this embodiment can prevent the center of gravity of the main body 2 from changing when the adjustment part 4 is peeled off. Also, by configuring it in this manner, the adjustment parts on the left and right sides of the base 3 can be removed simultaneously, making it easier to adjust the weight. Furthermore, since the weight 1 of this embodiment does not have exposed slits on the front or back, it is more difficult to peel off.

[0058] <Modification 1 of Embodiment 2> 6A and 6B are external views for explaining an example of a fishing weight according to a first modification of the second embodiment, in which (a) is a plan view of the example, and (b) is a plan view of the example.

[0059] The weight 1 of the second embodiment is excellent in terms of operability in that the left and right adjustment parts of the base 3 can be simultaneously removed. On the other hand, since the main body 2 does not have an escape groove, when it is attached around the hook eye L2, it will interfere with the hook eye L2.

[0060] The weight 1 of this example is designed to solve such problems, and the main body 2 has a relief portion 21 provided in the base portion 3. In addition, the adjustment portion 4 is configured in a U-shape and is configured to surround three sides of the base portion 3 excluding the opening side of the relief portion 21.

[0061] By configuring the weight 1 in this way, it is possible to improve operability and easily attach it around the hook eye L2. In addition, since the slit is not exposed on the front side, it is relatively difficult to peel off.

[0062] In this example, the weight 1 may have all of the adjustment parts 4 configured in a U-shape, as shown in Figure 6(a), or may have some of the adjustment parts 4 (adjustment parts 4a and 4c shown in the figure) configured in a U-shape and some of the adjustment parts 4 (one set of adjustment parts 4b shown in the figure) configured in a L-shape, as shown in Figure 6(b).

[0063] <Modification 2 of Embodiment 2> Fig. 7 is an external view and a plan view for explaining an example of a fishing weight according to Modification 2 of Embodiment 2. Fig. 8 is a diagram for explaining an example of adjusting the main body weight.

[0064] The weight 1 of the second embodiment is excellent in terms of operability, in that the left and right adjustment parts of the base 3 can be removed simultaneously. It is also excellent in that it can prevent a change in the center of gravity of the main body 2 when the adjustment part 4 is peeled off. On the other hand, because the main body 2 does not have an escape groove, it will interfere with the hook eye L2 when attached around the hook eye L2.

[0065] The weight 1 of this example is intended to solve such problems, and is configured such that the relief portion 21 in the main body 2 cuts from the outer periphery of the adjustment portion 4 into the base portion 3, i.e., extends from the base portion 3 to the adjustment portion 4. In other words, the main body 2 of this example is configured such that the adjustment portion 4 wraps around the entire circumference of the base portion 3, excluding the opening of the relief portion 21.

[0066] By configuring the weight 1 of this example in this way, it can be easily attached around the hook eye L2 while improving operability and minimizing changes in the center of gravity. In addition, since the slits are not exposed on the front or back, it is relatively difficult to peel off.

[0067] <Modification 3 of Embodiment 2> 9A to 9D are external views for explaining an example of a fishing weight according to the third modification of the second embodiment, in which (a) is a plan view, (b) is a right side view, (c) is a front view, and (d) is a rear view.

[0068] The weight 1 of this example differs from the second modification of the second embodiment in that it is configured in a roughly elliptical shape that is long in the front-to-rear direction in order to reduce water resistance and make it more difficult to peel off.

[0069] Preferably, as shown in the figure, the weight 1 has a shape in which the opening of the relief portion 21 and the corners of the bottom are rounded, which makes it more difficult for the weight 1 to peel off.

[0070] The weight 1 is preferably configured so that the weights of each component are equal. The base portion 3 and the adjustment portions 4a and 4b each weigh, for example, 0.5 g. This allows the weight 1 to be peeled off in constant weight increments of 0.5 g.

[0071] When the weight 1 has the first adjustment portion 4a and the second adjustment portion 4b as shown in the figure, the length C of the main body 2 is, for example, 15 mm to 60 mm, preferably 22 mm to 48 mm, more preferably 24 mm to 40 mm, for example, 31 mm. The width D is, for example, 5 mm to 20 mm, preferably 6 mm to 16 mm, more preferably 8 mm to 12 mm, for example, 10 mm. The width B of the relief portion 21 is, for example, 1 mm to 3 mm, preferably 1.2 mm to 2.4 mm, more preferably 1.2 mm to 2 mm, for example, 1.5 mm. When the main body 2 is made of a lead sheet material, the thickness is, for example, 0.5 mm.

[0072] In the above explanation, an example has been described in which the weight is adjusted to decrease by first attaching the weight sinker 1 to the lure L and then peeling off the symmetrical outer adjustment parts 4, but it is also possible to attach the base part 3 first, and then attach the symmetrical inner adjustment parts 4 to both sides of the base part 3 to adjust to increase the weight. The weight sinker 1 may also be attached to fishing equipment other than a lure.

[0073] The above describes the embodiment and its modifications of the fishing weight according to the present invention, but these are merely examples of the present invention and the present invention is not limited to these. The present invention also includes combinations of the above embodiments and their modifications, as well as various other modifications. Various additions, modifications, and partial deletions are possible within the scope of the conceptual idea and spirit of the present invention, which can be derived from the content defined in the claims and their equivalents.
