Description

Technical Field

[0001] This invention relates to a hook for use on a fishing line, the fishing line being used to hold fish caught by an angler in the water. Background Technology

[0002] Various types of locking structures exist for the hooks used in fishing lines. For example, the snap-on type shown in Patent Document 1 and the spring type shown in Patent Document 2 are known. The snap-on type locks the free end of the hook into a U-shaped locking section in plan view, and the locking is released by moving the free end against applied force from the locking section. The spring type locks the free end of the hook into the inner periphery of a spring mounted on a spring retainer on the hook body, and the locking is released by allowing the spring to contract against applied force, thus freeing the movement of the free end.

[0003] Patent documents Patent Document 1: Utility Model Registration No. 3129061 Patent Document 2: Japanese Utility Model Publication No. 55-58882 Summary of the Invention

[0004] Since hooks on fishing lines can keep fish alive and swimming, when a fish becomes agitated, the locking mechanism experiences tensile, compressive, torsional, or combined forces. Therefore, in a snap-on structure, if a fish becomes agitated and exerts significant force on the locking mechanism, the locking may disengage, allowing the fish to escape. Similarly, in a spring-loaded structure, if the spring slips or contracts due to waves colliding with rocks or the shore, the locking may also disengage, allowing the fish to escape. In other words, hooks on fishing lines need a structure that can maintain the fish's locking position even under external factors such as agitated fish or waves. On the other hand, making the locking mechanism too rigid or requiring excessive effort can lead to decreased operability.

[0005] The present invention solves the problems of the prior art. The technical problem to be solved is to provide a hook for fishing lines that is not easy to release from the locked state and has good operability.

[0006] To achieve the above objectives, the hook for fishing line according to the present invention is characterized by comprising a hook body and a spring mounted on the hook body, the hook body having: a base; a spring retaining portion connected to the base and retaining the spring on its outer periphery; an extension portion extending laterally relative to the spring retaining portion; a fish retaining portion connected to the extension portion, being curved and passing through the fish; and a tip portion connected to the fish retaining portion and extending toward the base, the tip portion being switchable to any one of the following states: a first locking state locked to the inner periphery of the spring, a second locking state locked to the extension portion, or a released state after being released from the first locking state and the second locking state.

[0007] Furthermore, in one embodiment, the top end is located between the protrusion and the spring in the second locking state.

[0008] Furthermore, in one embodiment, the inner edge of the protrusion is located further inward than the outer periphery of the spring.

[0009] Furthermore, in one embodiment, the top portion is characterized by always applying force toward the protruding portion.

[0010] Furthermore, in one embodiment, the top end is located above the center of the spring in the length direction, both in the first locking state and the second locking state.

[0011] Furthermore, in one embodiment, the fish-holding portion is characterized by having a straight portion extending along the axial direction of the spring and a curved portion connected to the straight portion.

[0012] Furthermore, in one embodiment, the hook body is characterized by having an extension portion connected to the protruding portion and extending to the opposite side of the protruding portion relative to the spring, and being able to additionally switch to a third locking state in which the lower end of the spring is pressed into and engaged with the extension portion during the first locking state or the second locking state.

[0013] Furthermore, in one embodiment, the spring pitch at the lower end of the spring is set such that, when the spring is rotated about an axis, the end is pressed into and engaged with the extension portion.

[0014] According to the present invention, when the tip of the hook for stringing fishing line is in a first locked state, even if it is disengaged from the locked state due to some external cause, the tip can automatically transition to a second locked state, thus maintaining the locked state of the tip. Furthermore, since the locked or released state can be switched by contracting the spring and operating the tip, good operability is achieved.

[0015] Furthermore, according to one embodiment of the invention, since the movement of the top end is prevented by the spring, even in the second locking state, the locking state can be prevented from being released.

[0016] Furthermore, according to one embodiment of the present invention, the tip portion can be stably locked in the protrusion.

[0017] Furthermore, according to one embodiment of the present invention, the tip is not easily dislodged, thus enabling the first locking state and the second locking state to be stably maintained.

[0018] Furthermore, according to one embodiment of the present invention, the fish can be held on the curved portion near the straight portion, and deformation of the hook body can be prevented.

[0019] Furthermore, according to one embodiment of the present invention, by switching to the third locking state, the lower end of the spring is pressed into and engaged with the extension setting portion, thus preventing the spring from contracting and making the first and second locking states more secure.

[0020] Furthermore, according to one embodiment of the present invention, the third locking state can be easily switched simply by rotating the spring. Attached Figure Description

Detailed Implementation

[0022] The hook 1 for stringing fish lines according to an embodiment of the present invention will be described with reference to the accompanying drawings. In the following description, "up and down" and "left and right" are used to indicate the direction of the hook. Figure 1 Using the indicated direction as a reference, when referred to as "front and back", it is based on... Figure 3 The directions shown are for reference only. The terms "up and down," "left and right," and "front and back" are added for ease of explanation and do not limit the direction of the invention. In various embodiments, the same parts are labeled with the same symbols and detailed descriptions are omitted.

[0023] like Figure 1 As shown, the fishing line hook 1 includes a hook body 2 and a spring 3. The fishing line hook 1 is a tool for keeping a fish (not shown) in the water while it is swimming. The fish can be secured to the fish holding part 17 of the fishing line hook 1 and tied to a fixed part such as land or a boat via the connector S and connecting part R mounted on the base 11. The connecting part R can be, for example, a buckle, rope, carabiner, or a combination thereof. When using a rope, the rope can also be wound onto a rope holder.

[0024] The hook body 2 includes a base 11, a first spring retaining part 12, a folding part 13, a second spring retaining part 14, a protruding part 15, an extension setting part 16, a fish retaining part 17, and a top part 18. The hook body 2 is formed by bending a slender metal part with a constant outer diameter.

[0025] The base 11 is formed on the upper part of the hook body 2 and is curved. In order to prevent the spring 3 from coming off upward, the width of the base 11 in the left-right direction is larger than the outer diameter of the spring 3.

[0026] The first spring retaining portion 12 is connected to one side of the base portion 11 and extends in a straight line along the central axis C of the spring 3. The fold-back portion 13 is a portion that bends upward continuously from the lower end of the first spring retaining portion 12 and folds back.

[0027] The second spring retaining portion 14 extends continuously in a straight line along the axial direction of the spring 3 from the other side of the base 11. The first spring retaining portion 12 is substantially parallel to the second spring retaining portion 14. Figure 3 As shown, the first spring retaining portion 12 and the second spring retaining portion 14 are arranged to face each other at a central position in the front-rear direction while being separated from each other. The first spring retaining portion 12 and the second spring retaining portion 14 constitute the "spring retaining portion" of the retaining spring 3.

[0028] The protrusion 15 is connected to the second spring retaining portion 14 and extends horizontally relative to the second spring retaining portion 14 from the central axis C of the spring 3 to the side (left side). Figure 3 As shown, the protrusion 15 is U-shaped when viewed from above. The width (gap in the front-to-back direction) of the protrusion 15 is slightly larger than the outer diameter of the top portion 18. The protrusion 15 includes a straight portion 15a, a curved portion 15b, and a straight portion 15c.

[0029] The straight portion 15a is connected to the second spring retaining portion 14 and extends straight to the left. The curved portion 15b is the part that is connected to the straight portion 15a and bends. The straight portion 15c extends straight between the curved portion 15b and the extending portion 16. The inner edge 15d of the straight portion 15c is located further inward (towards the central axis C) than the outer peripheral edge 31 (the foremost edge) of the spring 3. In addition, the protrusion 15 can be shaped to extend continuously to the side from the second spring retaining part 14 and lock the top part 18, for example, it can be other shapes such as V-shape or W-shape when viewed from above.

[0030] like Figure 1 and Figure 2 As shown, the extension portion 16 is connected to the protrusion portion 15 and extends in a straight line relative to the spring 3 to the side opposite to the protrusion portion 15. The extension portion 16 is approximately orthogonal to the central axis C and is extended to the vicinity of the folding portion 13.

[0031] like Figure 1 As shown, the fish holding part 17 includes a first straight part 19, a curved part 20, and a second straight part 21. The first straight part 19 is connected to the extension part 16 and extends downward in a straight line.

[0032] The curved portion 20 is connected to the lower end of the first straight portion 19 and is curved to bulge downwards. The second straight portion 21 is connected to the curved portion 20 and extends in a straight line toward the spring 3. The second straight portion 21 is inclined to the central axis C. Figure 2 As shown, the boundary 22 between the second straight section 21 and the top section 18 is located on the protrusion 15 (extension setting section 16).

[0033] The top portion 18 is connected to the second straight portion 21 and extends upward in a straight line. For example... Figure 3 As shown, the top end 18 contacts the inner periphery 32 of the spring 3. Since the top end 18 is formed by bending a metal component, it is always subjected to force towards the left (the side of the protrusion 15). Figure 2 As shown, the position of the top end of the top part 18 can be set appropriately, but in this embodiment, it is located higher than the center of the spring 3 in the length direction (vertical direction).

[0034] Spring 3 is a helical spring, mounted on the outer periphery of the spring retaining portions (first spring retaining portion 12 and second spring retaining portion 14). The upper side of spring 3 is restricted from vertical movement by the base 11, and the lower side by the fold-back portion 13. Figure 6 As shown, the spring pitch of the upper end 3a of the spring 3 is approximately zero. That is, the adjacent components of the spring 3 at end 3a are in close contact with each other. On the other hand, the spring pitch of the lower end 3b of the spring 3 is the same as or greater than that of the other parts. That is, the adjacent components of the spring 3 at the lower end 3b are spaced apart from each other.

[0035] Next, the locking and releasing states will be explained. The hook 1 for fishing line in this embodiment can achieve a first locking state, a second locking state, a third locking state, and a releasing state, depending on the usage. The third locking state has two modes: the mode of the first locking state and the mode of the second locking state.

[0036] (First locking state) The first locking state is Figure 1 The state shown. This first locking state is typically used to securely hold the caught fish on the hook body 2. In the first locking state, the tip 18 is locked to the inner periphery 32 of the spring 3 while applying force outward (see reference). Figure 3 The top portion 18 is covered by the spring 3. Furthermore, the lower end 3b of the spring 3 is located higher than the extension portion 16.

[0037] (Status lifted) The state is Figure 7The state shown. When changing from the first locked state to the released state, firstly, the spring 3 is contracted upwards until the tip 18 is fully exposed. Then, when holding the fish-holding part 17, and as shown... Figure 3 As shown, the top part 18 moves to the right against the force applied by the top part 18, and moves to the outside of the folding part 13 and the outside of the spring 3 (see reference). Figure 3 When arrow F is drawn, it can become Figure 7 The released state. In the released state, since the tip 18 is released, the caught fish can pass through the fish holding part 17. When returning the tip 18 from the released state to the first locking state, it is only necessary to perform the order in reverse of the release order described above.

[0038] (Second locking state) The second locking state is Figure 8 The state shown is as follows. In the first locking state that holds the fish, even if the first locking state is released by some external force, this second locking state will still function as a safety device to maintain the holding state of the fish, but it can also be consciously switched from the first locking state to the second locking state by the user. In this case, the spring 3 is contracted upward until the tip 18 is fully exposed. Then, due to the force applied to the tip 18, the tip 18 will automatically pop out in the extension 15 and enter the second locking state. Even in the second locking state, the tip of the tip 18 will be located higher than the center of the spring 3 in the longitudinal direction (vertical direction). In addition, the lower end 3b of the spring 3 is located higher than the extension part 16.

[0039] Because a force is applied to the tip 18, the device remains locked to the protrusion 15 even in the second locked state. Figure 9 As shown, when viewed from above in the second locked state, the top portion 18 is located between the protrusion 15 and the spring 3. In other words, in the second locked state, the movement of the top portion 18 will be prevented by the spring 3 as long as the spring 3 is not retracted.

[0040] When returning from the second locking state to the first locking state, while the spring 3 is contracted upward, the top part 18 moves into the interior of the spring 3 against the force applied by the top part 18. Then, by releasing the contraction of the spring 3 and covering the top part 18 with the spring 3, the top part 18 can be locked onto the inner periphery 32 of the spring 3. On the other hand, since the order of changing the tip 18 from the second locking state to the released state is the same as that of the first locking state (release state), it is omitted.

[0041] (Third locking state (during the first locking state)) The third locking state during the first locking state Figure 10 The state shown is described above. This third locking state is an additional reinforcing unit used to more firmly maintain the first locking state. In the first locking state, by rotating the spring 3 about the central axis C in one direction, the spring 3 moves downward relative to the hook body 2, and the lower end 3b of the spring 3 is pressed and engaged with the extension portion 16 in a winding manner. This prevents the spring 3 from contracting. Furthermore, when the spring 3 is rotated, the lower end 3b of the spring 3 is also pressed and engaged with the second straight portion 21 in a winding manner. This further securely prevents the spring 3 from contracting. Additionally, when the spring 3 is rotated in the opposite direction, the third locking state can be released, and it is possible to return to only the first locking state.

[0042] Normally, users keep the fish in the first locking state after catching it, but by additionally switching to the third locking state, the fish-holding function can be more securely performed.

[0043] (Third locking state (during the second locking state)) The third locking state during the second locking state is Figure 11 The state shown is described above. This third locking state is an additional reinforcing unit used to more firmly maintain the second locking state. By rotating the spring 3 around the central axis C from the second locking state, the spring 3 moves downwards, and the lower end 3b of the spring 3 is pressed and engaged with the extension portion 16 in a winding manner. This prevents the spring 3 from contracting. Furthermore, when the spring 3 is rotated in the opposite direction, the third locking state can be released, and it is possible to return to only the second locking state.

[0044] Even if, for some reason, the fish is held in the second locking state instead of the first locking state, a strong fish-holding function can still be achieved by additionally switching to the third locking state. For example, when a fish is held in the first locking state and then becomes locked in the second locking state due to some external cause, the user can additionally switch to the third locking state to hold the fish securely.

[0045] According to the above-described embodiment, the hook 1 for fishing line can automatically transition to the second locking state even if the first locking state is released due to some external cause when it is in the first locking state, thus preventing the locking state of the top part from being released. Furthermore, since locking or releasing can be performed by contracting the spring 3 and operating the top part 18, operability is also good.

[0046] Furthermore, since in this embodiment, in such Figure 9In the second locked state shown, the top part 18 is located between the protrusion 15 and the spring 3, and the movement of the top part 18 is blocked by the spring 3. Therefore, even in the second locked state, the locked state is not easy to release.

[0047] In addition, such as Figure 9 As shown, in this embodiment, the inner edge 15d of the protrusion 15 is located further inward than the outer periphery 31 of the spring 3, so that the top end 18 can be stably locked in the protrusion 15 in the second locking state.

[0048] Furthermore, since the top part 18 is always forced toward the protruding part 15 in this embodiment, the top part 18 is not easy to come out and can be stably locked in the first locking state and the second locking state.

[0049] Furthermore, since in this embodiment, in the first locking state and the second locking state, the top part 18 is located higher than the center in the length direction of the spring 3, the top part 18 is not easy to come out, and it can be stably locked in the first locking state and the second locking state.

[0050] Furthermore, in this embodiment, the fish holding part 17 includes a first straight portion (straight portion) 19 extending along the axial direction of the spring 3 and a curved portion 20 connected to the first straight portion 19. As a result, the fish is easily held on the curved portion 20 near the first straight portion (straight portion) 19, and the hook body 2 is less prone to deformation.

[0051] Furthermore, in this embodiment, the hook body 2 has an extension portion 16 connected to the extension portion 15 and extending relative to the spring 3 to the side opposite to the extension portion 15. Therefore, in the first locking state or the second locking state, it is possible to switch to a third locking state in which the lower end 3b of the spring 3 is pressed and engaged on the extension portion 16. Thus, since the lower end 3b of the spring 3 is pressed and engaged on the extension portion 16 in the third locking state, the retraction of the spring 3 can be prevented, and the first locking state and the second locking state can be maintained more securely.

[0052] Furthermore, in this embodiment, the spring pitch of the lower end portion 3b on the extension portion 16 side of the spring 3 is set such that when the spring 3 is rotated about its axis, the lower end portion 3b is pressed into and engaged with the extension portion 16. Thus, by simply rotating the spring 3, one can transition from the first locked state or the second locked state to the third locked state. Conversely, by simply rotating the spring 3, one can return from the third locked state to either the first locked state or the second locked state only.

[0053] Although the embodiments of the present invention have been described above, appropriate design changes may be made without departing from the spirit of the present invention.
