Description

Technical Field

[0001] The utility model relates to a line cutter used for winding a fishing line onto an outer circumference and pulling out (tearing off) the bottom-engaged fishing line when a fishing gear is entangled with an obstacle or the like and is stuck on the bottom during actual fishing. Background Art

[0002] When fishing with a reel, the fishing line may become entangled with an obstacle, causing it to get stuck, making it impossible to reel in the line. In such a situation, forcibly bending the fishing rod to unsnag it poses a risk of breaking the rod. Furthermore, when the rod is used to pull the line along the line, the high tension exerts a significant load on the reel's components, such as the wire loop support and line roller, potentially damaging the reel.

[0003] Therefore, a known line cutter allows the user to reel in the line when the fishing rig is stuck and cannot be reeled in with a reel. The user then uses their own strength to forcefully pull and cut the stuck fishing line (tear it off) (see, for example, Patent Document 1). Furthermore, as described in Non-Patent Document 1, a conventional line cutter is also known that has a double-tube structure consisting of an outer tube and a middle tube. This double-tube structure allows the line cutter to be used as a fishing line tying tool by separating the outer tube and the middle tube and winding the fishing line onto each tube to perform a predetermined operation. This improves the knotting force while minimizing bulging and knot hairs at the knotted portion, and can also be used to secure the knot.

[0007] However, conventional double-tube bolt cutters, formed from a cylindrical metal material and covered with a rubber tube, present a significant weight penalty. Furthermore, since the outer and middle tubes are connected by screws, inserting and removing the middle tube is cumbersome. Furthermore, if sand gets stuck or rust forms, the middle tube becomes difficult to rotate relative to the outer tube, compromising operability.

[0008] The present invention is developed with an eye on the problems in the prior art, and aims to provide a wire breaker with good operability and usability.

[0009] In order to achieve the above-mentioned purpose, the utility model relates to a line breaker for winding a bottom-hanging fishing line onto an outer circumference and breaking the fishing line wound by the user, characterized in that the line breaker comprises an outer tube and a middle tube that can enter and exit the interior of the outer tube, and the inner surface of the outer tube and the outer surface of the middle tube have a surface shape that can maintain the storage state of the middle tube when the middle tube is stored in the interior of the outer tube.

[0010] According to the wire cutter of the present invention, since the inner surface of the outer tube and the outer surface of the middle tube have surface shapes that maintain the storage state of the middle tube, the middle tube can be removed from the outer tube simply by moving the middle tube relative to the outer tube in the axial direction. Since it does not use a screw-type structure as in the past, the insertion and removal operability of the middle tube can be improved, and it is also easier to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Hereinafter, embodiments of the wire cutter according to the present invention will be described with reference to the accompanying drawings.

[0021] Figures 1 to 5 1 is a diagram showing a first embodiment of a wire breaker. Figure 1 It's a stereogram. Figure 2 It means in Figure 1 The three-dimensional view of the wire cutter after the middle cylinder is removed from the outer cylinder is shown. Figure 3 This is a cross-sectional view for explaining an example of the surface shape of the inner surface of the outer tube and the outer surface of the middle tube when the middle tube is housed in the outer tube and the stored state is maintained.

[0022] The wire cutter 1 of this embodiment comprises: an outer cylinder 10 formed into a substantially cylindrical shape; and an inner cylinder 30 having a smaller diameter than the outer cylinder 10, housed in the outer cylinder 10, and formed into a substantially cylindrical shape. The outer cylinder 10 is formed of a lightweight and high-strength material such as a hard resin or a high-strength light metal (aluminum, etc.), and has a central portion at one end ( Figure 1 A reinforcing ring 11 is installed or integrally formed on the opening portion (the upper end in the shown state).

[0023] The reinforcing ring 11 has the function of preventing cracks in the opening of the outer tube 10, but the overall design can be improved by forming it from a different material from the outer tube 1, giving it a color, or forming a recess 11a along the circumference.

[0024] The outer surface 10a of the outer cylinder 10 is coated with a resin sheet 12 made of a flexible material, such as a thermoplastic elastomer. Since this resin sheet 12 is the part around which the fishing line is wound when it is cut, a relatively soft material is used to prevent damage to the wound fishing line. Furthermore, a flange 10b is formed at the lower end of the outer cylinder 10 to stabilize the wrapped resin sheet 12.

[0025] The middle cylinder 30 is formed by injection molding a lightweight material, such as a thermoplastic resin. Typically, the middle cylinder 30 is used infrequently and is housed within the outer cylinder 10, so it is preferably formed of a lightweight material. In particular, molding it into a hollow structure allows for cost reduction and weight reduction.

[0026] The inner surface 10c of the outer tube 10 and the outer surface 30a of the middle tube 30 have surface shapes that keep the middle tube 30 in the stored state when the middle tube 30 is stored in the outer tube 10. Figure 1 and Figure 3 In the stored state of the middle tube 30 shown, the axial movement of the middle tube 30 is restricted, and the middle tube 30 is configured not to accidentally fall out of the outer tube 30 .

[0027] Such a stored state can be maintained by forming the inner surface 10c of the outer cylinder 10 and / or the outer surface 30a of the middle cylinder 30 into a shape that engages with each other, for example, a tapered surface along the axial direction.

[0028] In this embodiment, the end (lower end) 10d of the outer cylinder 10 is formed into a substantially straight shape, while the end (lower end) 30d of the middle cylinder 30 is formed into a tapered surface 30e (a radially outward tapered surface) that increases in diameter as it transitions downward. This configuration allows the middle cylinder 30 to be press-fitted into the outer cylinder 10 and retained therewith.

[0029] Furthermore, as described above, by pre-forming the tapered surface 30e on the end of the middle cylinder 30, the middle cylinder 30 can be easily attached and detached, thereby improving usability. In particular, when the middle cylinder 30 is pressed into the outer cylinder 10, the tapered surface 30e generates pressure by rebounding against the tapered surface, and since the two are engaged by the strong pressing force (friction), the middle cylinder 30 is less likely to be accidentally removed from the outer cylinder 10.

[0030] Furthermore, the surface shapes that engage to maintain the inner tube 30 retracted relative to the outer tube 10 can be not only a combination of a tapered surface formed on the outer surface 30a of the inner tube 30 and a straight surface formed on the inner surface 10c of the outer tube 10, as described above. Alternatively, the reverse can be employed, i.e., the outer surface 30a of the inner tube 30a can be a straight surface, while the inner surface 10c of the outer tube 10 can be a tapered surface with a decreasing diameter (a radially inward tapered surface). Furthermore, tapered surfaces with different orientations can be formed on both the inner surface 10c of the outer tube 10 and the outer surface 30a of the inner tube 30. Furthermore, in the tapered engagement method, while the tapered surface is formed at the end in this embodiment to facilitate insertion and removal of the inner tube 30, the engagement position is not particularly limited. Furthermore, as the surface shape for engaging the middle cylinder 30 with the outer cylinder 10, the following appropriate configurations can be adopted, such as a configuration in which recesses and protrusions are formed along the circumferential direction on the inner surface 10 c of the outer cylinder 10 and the outer surface 30 a of the middle cylinder 30 to form a concave-convex fit, or a configuration in which a slight difference in diameter is formed between the inner diameter of the outer cylinder 10 and the outer diameter of the middle cylinder 30 and the two are press-fitted together.

[0031] It is preferable that a flange 30A projecting radially outward is formed on the end portion of the middle cylinder 30 .

[0032] By forming the flange 30A in advance, it is possible to facilitate the removal operation when pinching the middle tube 30 to remove it from the outer tube 10. The flange 30A may be formed over 360°, or may be formed at a plurality of locations at predetermined intervals in the circumferential direction to perform appropriate deformation.

[0033] like Figure 3 As shown, the outer cylinder 10 of this embodiment has openings 10A and 10B at both ends, and is configured so that the end (disk-shaped flat surface) 32 of the middle cylinder 30 is exposed in the upper end opening 10A. Preferably, a member for axially moving the middle cylinder 30 while it is held on the outer cylinder 10 is provided at the end of the middle cylinder 30. The member for moving the middle cylinder 30 can be any member that can be pinched (lifted) or pressed (pressed) with the fingers when moving the middle cylinder 30 relative to the outer cylinder 10. In this embodiment, a protruding member (hereinafter also referred to as a pressing portion 35) is formed to protrude axially from the surface of the end 32 to enable unobstructed pressing operation.

[0034] like Figure 4 As shown in (a) and (b), when the thumb is used to press the pressing portion 35 in the direction of the arrow (downward) while holding the outer tube 10, the retaining function of the outer tube 10 and the middle tube 30 is released, and the middle tube 30 moves downward and separates from the outer tube 10.

[0035] Furthermore, to accommodate attachment of other items, such as a loop-type hook 60, the pressing portion 35 of this embodiment includes a locking structure with an opening 35a through which the hook 60 passes. The hook 60 is attached so that it can be caught on the angler's clothing during actual fishing. When the hook 60 is attached to the opening 35a, it protrudes radially outward from the opening 10A of the outer tube 10, thereby preventing the middle tube 30 from accidentally falling. Furthermore, in addition to the bridge-like shape shown in the figure, the locking structure can also be configured as a frame or by forming a hole in a plate member, or by other suitable deformations.

[0036] Next, a description will be given of usage examples and operational effects of the disconnector 1 having the above-described configuration.

[0037] During actual fishing, if the fishing rig gets stuck and the reel cannot be used to reel in the fishing line, the user can wind the fishing line onto the outer cylinder 10 and then forcefully pull the outer cylinder 10 to cut the fishing line or the fishing rig (tear it off). Because the outer surface 10a of the outer cylinder 10 is coated with a resin sheet 12, it is flexible and has a non-slip function, so the wound fishing line will not be cut by the resin sheet.

[0038] Furthermore, in addition to the function of winding and pulling the fishing line, the line cutter 1 can also be used as a tool for tying fishing lines together (knotting tool).

[0039] like Figure 4 As shown, the user presses down the pressing portion 35 of the middle tube 30 to separate the middle tube 30 housed in the outer tube 10. Then, the fishing line S1 on the reel side is wound around the outer tube 10 (see Figure 5 (a)), and wind the fishing line S2 on the fishing gear side around the middle tube 30 (refer to Figure 5 (b)). In this state, by aligning the fishing lines S1 and S2 (refer to Figure 5 (c)) and pull the outer tube 10 and the middle tube 30 to both sides, so that the fishing lines S1 and S2 (see Figure 5 (d) Knotting: By pulling, the knot 65 is tightened strongly, the knot can be reduced, and the knot can be tied tightly.

[0040] The aforementioned line cutter 1 eliminates the need for conventional threaded connections between the outer tube 10 and the middle tube 30, eliminating the risk of grit or rust on the threads, thereby improving usability. Furthermore, since the outer tube 10 is made of a lightweight, high-strength material and the portion where the fishing line is wound is coated with a resin sheet 12, it is fully capable of functioning as a line cutter.

[0041] Furthermore, since the middle cylinder 30 has a hollow structure and is made of resin, rather than being a cut product, it can be lightweight, facilitates the fastening operation of the knot 65, and reduces costs. Furthermore, the inner surface 10c of the outer cylinder 10 and the outer surface 30a of the middle cylinder 30 are aligned with each other. When the middle cylinder 30 is stored within the outer cylinder 10, the surface shape of the stored state of the middle cylinder 30 is maintained. Furthermore, when removing the middle cylinder 30 from the outer cylinder 10, simply pressing the pressing portion 35 is sufficient, thereby improving operability.

[0042] Figure 6 and Figure 7 2 is a diagram showing a second embodiment of the wire breaker. Figure 6 (a) is a stereoscopic view, (b) is a side view, Figure 7 (a) From the other direction Figure 6 (b) a side view for observation, Figure 7 (b) is along Figure 7 (a) is a cross-sectional view along line AA.

[0043] In describing the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed descriptions thereof are omitted.

[0044] The wire cutter 1A of this embodiment is configured such that the middle cylinder 30 can be freely extended and retracted between a state housed within the outer cylinder 10 and a state in which it can be moved (pulled out) in the axial direction and protrudes axially relative to the outer cylinder 10. The outer surface 30a of the middle cylinder 30 and the inner surface 10c of the outer cylinder 10 are relatively axially slidable. A circumferential protrusion 30f is formed on the outer surface 30a of the middle cylinder 30 at its lower end in the longitudinal direction, and a circumferential protrusion 30g is formed at its lowest end.

[0045] The middle tube 30, equipped with these protrusions 30f and 30g, slidably abuts the inner surface 10c of the outer tube 10 with friction, maintaining its retracted position when the middle tube 30 is housed within the outer tube 10. Furthermore, when the protruding member 35 of the middle tube 30 is pulled out, the protrusion 30f engages with the inner surface (opening 10A) of the reinforcing ring 11 of the outer tube 10, providing a stop function for the middle tube 30 at an intermediate position. Specifically, when pulling out the middle tube 30, the user can choose to either engage the protrusion 30f with the opening 10A and stop midway, or continue pulling the middle tube 30 out until the protrusion 30g engages with the opening 10A and is fully extended (the structure allows the middle tube 30 to be extended or retracted relative to the outer tube 10 in two different degrees).

[0046] With the above configuration, the user can choose between two usage methods: using the wire cutter with only the outer tube 10 shortened; and using the wire cutter with the outer tube 10 and the inner tube 30 extended to the maximum extent.

[0047] In order to further enable step-by-step expansion and contraction, a plurality of protrusions 30f may be provided in the axial direction. Furthermore, in order to enable stepless expansion and contraction adjustment, only the protrusions 30g may be used to generate a strong friction force with the inner surface 10c of the outer tube 10.

[0048] Furthermore, it is preferable that a detachable closing member (a lid-like cover) 38 is attached to the lower end portion of the outer tube 10 to close the opening, so that the middle tube 30 can be removed from the outer tube 10 .

[0049] With this configuration, the fishing line knotting tool can be used as well, similarly to the first embodiment.

[0050] Although the embodiments of the present invention have been described above, the present invention is not limited to the configurations of the embodiments, and various modifications are possible.

[0051] For example, the cross-sectional shape of the outer tube 10 and the middle tube 30 is not limited to a circle, but may be a polygon, and may be appropriately deformed. In addition, the middle tube 30 may also be configured so that it can be inserted from the opening 10A side of the outer tube 10.

[0052] By coating the outer surfaces of the outer tube 10 and the middle tube 30 with components of varying softness (hardness), it is possible to differentiate between the types and thicknesses of fishing lines used. For example, in a fishing line configuration where thin fishing line (PE) is used on the reel side and thick fishing line (leader; fluoro, nylon) is used on the rig (lure) side, the thin fishing line can become entangled when winding it around the soft material. Therefore, the thin fishing line on the reel side can be wound around a tube with a higher surface hardness, while the thick fishing line on the rig side can be wound around a tube with a lower surface hardness. Furthermore, if the reel side uses thin fishing line and the lure side uses thick fishing line, it is preferable to make the surface of the outer tube 10 harder than that of the middle tube 30 to prevent the fishing line from becoming entangled during the rig cutting operation.
