Summary of the Invention
Problems to be Solved by the Invention
[0004] In Patent Document 1 above, since the pair of front halves for clamping fish have substantially the same predetermined thickness, there is a problem that fish cannot be clamped under the following circumstances. For example, when the caught fish comes off the hook and lies on the ground at the fishing spot (the floor in the case of a fishing boat), one of the pair of front halves is inserted between the fish and the ground at the fishing spot, and then both front halves are closed to clamp the fish. However, if the front half has a predetermined thickness, it is difficult to insert the front half between the fish and the ground at the fishing spot, and there are cases where the fish cannot be clamped with the fish clamp, and early improvement is desired (the same applies to Patent Document 2).
[0005] The present invention has been made in view of the above circumstances and aims to provide a fish gripper that can easily grip fish lying on their side at fishing spots or on a boat. [Means for solving the problem]
[0006] The fish gripper of the present invention comprises a pair of blades located at the tip and capable of moving closer to and further apart from each other, a pair of operating parts located at the base end for operating the pair of blades, and a pivot point located at the base end of the pair of blades and at the tip end of the pair of operating parts, which rotatably connects the pair of blades and the pair of operating parts, wherein the pair of blades has a first blade and a second blade, and the blade thickness in the direction perpendicular to the direction of approach and separation at the tip of the pair of blades is such that the first blade is thinner than the second blade.
[0007] With the above configuration, for example, if a fish is lying on the ground (or the floor in the case of a fishing boat) at a fishing spot, the thin first blade can be easily inserted between the fish and the ground (or the floor in the case of a fishing boat), making it easier to position the pair of blades along the fish's body. This allows the fish to be quickly moved to the desired position by being gripped between the inserted first and second blades.
[0008] Furthermore, in the fish gripper of the present invention, when the pair of blades approach each other, the tip of the first blade and the tip of the second blade may intersect in the direction of approach and separation.
[0009] As described above, the tips of the first blade and the second blade intersect in directions of approach and separation, which allows the distance between the pair of blades to be reduced when they are close together, making it easier to grip even small fish.
[0010] Furthermore, the fish gripper of the present invention may have a bent portion in which the extension direction of the pair of operating portions bends so that the base ends of each other are close together, and the pivot point portion may be located at a position 45% to 65% from the tip relative to the total length of the fish gripper.
[0011] With the above configuration, the pair of blades can be spread wide, and the bent section with the base ends close together makes it easier to operate the control section, resulting in a good feel when using it.
[0012] Furthermore, the fish gripper of the present invention may be configured such that the second blade has a through portion that penetrates in the direction of approach and separation, and the tip of the first blade passes through the through portion when the pair of blades approach each other.
[0013] As described above, by configuring the tip of the first blade to pass through the penetration portion of the second blade, it is possible to suppress the enlargement of the blades in the direction perpendicular to the rotational direction, compared to a configuration in which the position of the tip of one blade is shifted relative to the tip of the other blade in a direction perpendicular to the rotational direction to prevent interference when the tips of the first and second blades approach each other. [Effects of the Invention]
[0014] As in the present invention, by making the first blade thinner than the second blade, it is possible to provide a fish gripper that can easily grip fish lying on the ground at fishing spots or on board a boat. [Brief explanation of the drawing]

[Figure 7]This is a view seen from VII of FIG. 6, showing the state immediately before a thinner blade is inserted between the fish lying on the fishing ground and the ground. [Figure 8] This is an explanatory view showing the state where the fish is sandwiched from both left and right by the fish clamping tool.
Embodiments for Carrying Out the Invention
[0016] Hereinafter, embodiments of the fish clamping tool of the present invention will be described based on the drawings. Note that one end side (tip side) in the longitudinal direction of the fish clamping tool 1 is taken as the front end side, the other end side (base end side) is taken as the rear end side, the short side direction orthogonal to the longitudinal direction (front-rear direction) of the fish clamping tool 1 is taken as the left-right direction, and the direction penetrating the paper surface in FIGS. 1 and 2 is taken as the up-down direction of the fish clamping tool 1, and the following description will be made accordingly.
[0017] The fish clamping tool 1 includes a first arm 2 and a second arm 3 that are rotatably connected to each other at an intermediate portion in the longitudinal direction (front-rear direction), and biasing means 4 that biases the first arm 2 and the second arm 3 toward the opening side. [[ID=1The first blade 5 comprises a metal tooth portion 51 having teeth on its inner surface, and a synthetic resin support portion 52 that supports the tooth portion 51. The tooth portion 51 is constructed as a plate with the same thickness (blade thickness) in the front-rear direction. The blade thickness D is the size in the direction perpendicular to the approach / separation direction and the front-rear direction at the tips of the pair of blades 5 and 6, as shown in Figure 3. In other words, the blade thickness is the size in the direction perpendicular to the plane containing the rotation direction of the first arm 2 and the second arm 3 (the vertical direction in this embodiment). The tooth portion 51 and the support portion 52 are integrated by insert molding, but they may also be integrated by adhesive or engagement.
[0021] As shown in Figure 2, the front end (tip) 51A of the tooth portion 51 protrudes forward from the front end 52A of the support portion 52. Therefore, as shown in Figure 3, the blade thickness D at the front end 51A of the first blade 5 is thinner than the blade thickness d at the front end (tip) 61A of the second blade 6. As a result, as shown in Figures 6 and 7, when a fish F is lying on the ground (floor surface in the case of a fishing boat) G of the fishing spot, the thin front end 51A of the first blade 5 can be tucked between the lying fish F and the ground (floor surface in the case of a fishing boat) G. By closing the tucked-in first blade 5 and the second blade 6, the fish F can be sandwiched and moved to the desired position. The blade thickness D of the front end 51A of the first blade 5 is preferably set in the range of 1.5 mm to 3.0 mm, and more preferably in the range of 1.8 mm to 2.5 mm. Furthermore, since the relationship between the fish F and the first blade 5 of the fish clamp 1 is difficult to see in Figure 6, Figure 7 shows the angle of the first blade 5 of the fish clamp 1 relative to the ground when the fish F is viewed from the front. In Figure 7, the angle H of the first blade 5 relative to the ground G is set to approximately 30 degrees, but the closer the angle is to being nearly parallel to the ground G, the easier it becomes to insert the thin front end 51A of the first blade 5 between the fish F and the ground (floor surface in the case of a fishing boat) G.
[0022] As shown in Figure 2, the tooth portion 51 includes a first tooth 53 formed on the inner surface of the front end portion 51A and a second tooth 54 formed between the front end portion 51A and the rear end portion.
[0023] The first teeth 53 of the first blade 5 are composed of multiple (in this embodiment, two, but any number) substantially triangular first projections 53a formed continuously in the front-rear direction, with the tops of the first projections 53a curving into rounded arcs when viewed from the left to right (see Figure 2).
[0024] As shown in Figure 2, the second teeth 54 of the first blade 5 are provided with six (or any number) second teeth, from the first to the sixth, which are roughly triangular in shape, starting from the rear end of the first projection 53a located at the rear end in the front-rear direction. The second teeth 54a, 54a adjacent to each other in the front-rear direction are formed with a curved surface 54b that is recessed outwards. The top of the first second projection 54a is located inward from the top of the first projection 53a, the top of the second second projection 54a is located further inward from the top of the first second projection 54a, the top of the third second projection 54a is located outward from the top of the second second projection 54a, the top of the fourth second projection 54a is located further outward from the top of the third second projection 54a, the top of the fifth second projection 54a is located inward from the top of the fourth second projection 54a, and the top of the sixth second projection 54a is located inward from the top of the fifth second projection 54a. In other words, the top of the fourth second projection 54a is located furthest outward, the tops of the second second projection 54a and the sixth second projection 54a are both located furthest inward, the tops of the third second projection 54a and the fifth second projection 54a are located in the inward-outward direction, and the top of the fourth second projection 54a is located between the tops of the second second projection 54a and the sixth second projection 54a. A line connecting the top of the second second projection 54a to the tops of the third second projection 54a, the fourth second projection 54a, the fifth second projection 54a, and the sixth second projection 54a forms a curved section where the center in the front-rear direction is located furthest inward, and both ends in the front-rear direction are located furthest outward. Therefore, as shown in Figure 8, the top of the second projection 54a easily conforms to one side Fa of the fish F to be gripped, and the curved surface 54b between adjacent second projections 54a, 54a in the front-rear direction makes line contact with one side Fa of the fish F, making it easier to grip the fish F stably.
[0025] The second blade 6 is provided with a first tooth 62 on the inner surface 61a of the front end 61A, and a second tooth 63 on the inner surface 61b between the rear of the front end 61A and the rear end. The inner surface 61a of the front end 61A is formed as a plane substantially parallel to the front-rear direction when the blades 5 and 6 in Figure 1 are closed, while the inner surface 61b between the rear of the front end 61A and the rear end is formed as a curved surface that is positioned outward towards the center in the front-rear direction. When removing a fishing hook from a fish, the first tooth 53 of the first blade 5 and the first tooth 62 of the second blade 6 can be used to grip the fish's mouth or gills.
[0026] The first teeth 62 of the second blade 6 are provided in two rows along the front-to-back direction at both the upper and lower ends (see Figure 5), and each first tooth 62 is composed of multiple (three in this embodiment, but any number) roughly triangular prism-shaped first projections 62a that are formed continuously in the front-to-back direction, and the top of the first projection 62a is curved in a rounded arc shape when viewed from the left to right.
[0027] The second teeth 63 of the second blade 6, like the first teeth 62, are provided in two rows along the front-rear direction at both the upper and lower ends, and each second tooth 63 is provided with multiple (23 in this embodiment, but any number) substantially square pyramidal second projections 63a with small gaps in the front-rear direction. All second projections 63a are the same size. As a result, the line connecting the tops of all the second projections 63a that protrude inward from the curved surface located further outward towards the center in the front-rear direction of the inner surface 61b is also curved, and as shown in Figure 8, the tops of many second projections 63a can easily come into contact with the other side Fb of the fish F being gripped. As a result, as shown in Figure 8, the first blade 5 grips the fish F by the curved surface 54b between the second protrusions 54a, 54a making continuous contact over a wide area with one side Fa of the fish F, and the second blade 6 has the tops of numerous second protrusions 63a biting into the other side Fb of the fish F, making it easier to securely grip the fish F.
[0028] The first arm 2 and the second arm 3 intersect in an X-shape in plan view, and are provided with a pivot point 9 at the intersection that allows them to rotate freely relative to each other. One of the pair of operating parts 7 and 8, the first operating part 7 (left side in Figure 1), is connected to the first blade 5 on the right side via the pivot point 9. The other operating part 8 (right side in Figure 1) is connected to the second blade 6 on the left side via the pivot point 9.
[0029] As shown in Figure 1, the pair of operating parts 7 and 8 have bent portions 7W and 8W in which their extension direction bends inward so that their rear ends (base ends) are close to each other. The first operating part 7 of the pair of operating parts 7 and 8 includes a first extension portion 7A that extends diagonally to the left rear from the pivot point portion 9, and a first gripping portion 7B that bends inward at the bent portion 7W at the end of the first extension portion 7A and extends to the rear. The second operating part 8 of the pair of operating parts 7 and 8 includes a second extension portion 8A that extends diagonally to the right rear from the pivot point portion 9, and a second gripping portion 8B that bends inward at the bent portion 8W at the end of the second extension portion 8A and extends to the rear. Through holes are formed in the inner portions of the first gripping portion 7B and the second gripping portion 8B to reduce weight. The through-holes consist of three holes formed along the front-to-back direction, with the two front holes being elongated holes 7a and 8a of approximately the same size and shape, and the two rear holes being elongated holes 7b and 8b, whose width in the left-to-right direction is larger than that of the front elongated holes 7a and 8a. By providing the bent portions 7W and 8W, the gap between the operating portions 7 and 8 can be suppressed, making it easier to close and operate the operating portions 7 and 8, and resulting in a good operating feel.
[0030] As shown in Figures 4 and 5, the pivot point 9 comprises an upper circular pivot part 91 located on the upper side, a lower circular pivot part 92 located on the lower side, and a connecting member 93 that rotatably connects the upper pivot part 91 and the lower pivot part 92 in a state where they are superimposed in the vertical direction. The rear end of the first blade 5 and the front end of the left operating part 7 are integrated with the upper pivot part 91. Also, the rear end of the second blade 6 and the front end of the right operating part 8 are integrated with the lower pivot part 92. Furthermore, it is preferable that the pivot point 9 be located at a position 45% to 65% from the front end (tip) of the total length of the fish gripper 1. This allows the pair of blades 5 and 6 to be spread wide.
[0031] As shown in Figures 4 and 5, the connecting member 93 comprises a first connecting portion 94 having a cylindrical shaft portion 94B that can be inserted into a lower through hole 92A formed in the center of the lower rotating portion 92 and an upper through hole 91A formed in the center of the upper rotating portion 91, and having an internal thread 94N formed on its inner circumferential surface, and a circular head 94A formed at one end (lower end) of the shaft portion 94B with an outer diameter larger than that of the lower through hole 92A; and a second connecting portion 95B having a shaft portion 95B that can be inserted into the upper through hole 91A and having an external thread 95N formed on its outer surface that can be screwed into and unscrewed from the internal thread 94N, and a circular head 95A formed at one end (upper end) of the shaft portion 95B with an outer diameter larger than that of the upper through hole 91A.
[0032] The biasing means 4 includes a coil spring 41 (see Figure 5) housed in an arc-shaped groove 91M formed in the upper rotating part 91, and a rod-shaped contact part 42 (see Figure 4) provided on the upper surface of the lower rotating part 92 so as to protrude upward, and which enters into the groove 91M of the upper rotating part 91 and contacts one end of the coil spring 41. Therefore, by operating the pair of operating parts 7 and 8 of the fish clamp 1, which is biased to the open state shown in Figure 2, toward the closing side so that they move toward each other, the pair of blades 5 and 6 are operated toward the closing side, and at the same time the contact part 42 rotates clockwise, moving the coil spring 41 toward the shortening side (see Figure 1). Then, when the hands are released from the pair of operating parts 7 and 8 of the fish clamp 1, the biasing force toward the extension side of the coil spring 41 pushes the contact part 42 within the groove 91M and rotates counterclockwise, causing the fish clamp 1 to open (see Figure 2).
[0033] The front end (tip) 61A of the second blade 6 has a through-hole 6A that penetrates in the direction of approach and separation (see Figure 4). The through-hole 6A is composed of a roughly rectangular through-hole that is long in the front-rear direction (longitudinal direction), and the front end (tip) 51A of the first blade 5 passes through the through-hole 6A when the pair of blades 5 and 6 approach each other (see Figure 1). In Figure 1, the pair of blades 5 and 6 are in their most closed state, and the first projections 53a, 53a of the tip 51A of the first blade 5 protrude to the left from the second blade 6. By configuring the front end (tip) 51A of the first blade 5 to penetrate the through-hole 6A of the second blade 6, it is possible to suppress the enlargement of blades 5 and 6 in the direction perpendicular to the direction of rotation compared to a configuration in which the position of the tip of one blade is shifted relative to the tip of the other blade in a direction perpendicular to the direction of rotation to prevent interference when the tips of the first blade 5 and the second blade 6 approach each other.
[0034] The present invention is not limited to the embodiments described above.
[0035] In the above embodiment, the tip of the first blade 5 is configured to pass through the penetration portion 6A of the second blade 6 so that the tips of the first blade 5 and the tips of the second blade 6 intersect in the approaching / moving direction, so that the tips of the first blade 5 and the tips of the second blade 6 do not interfere with each other when the pair of blades 5 and 6 approach each other. However, when the tips of the first blade 5 and the tips of the second blade 6 approach each other, the tip of one blade may be shifted in a direction perpendicular to the approaching / moving direction so that the tips of the two blades intersect in the approaching / moving direction, so that the tips of one blade do not interfere with each other.
[0036] Furthermore, in the above embodiment, the first blade 5 was composed of two members: a plate-shaped metal tooth portion 51 and a support portion 52 that supports the tooth portion 51. However, it may also be composed of a single member. In this case, the material can be any material, such as metal, synthetic resin, or composite material.
[0037] Furthermore, although a coil spring was used as the biasing means 4 in the above embodiment, a leaf spring, a torsion coil spring, or the like may also be used.
[0038] Furthermore, in the above embodiment, the front end (tip) of the second blade 6 is shown as a through-hole 6A that penetrates in the direction of approach and receding, but it may also be a notch.
[0039] Furthermore, in the above embodiment, the blade thickness D at the front end 51A of the first blade 5 is made thinner than the blade thickness d at the front end (tip) 61A of the second blade 6. However, the blade thickness of the first blade 5 over its entire length in the front-rear direction may be made thinner than the blade thickness d at the front end (tip) 61A of the second blade 6. Alternatively, the thickness D at the front end 51A of the first blade 5 may be formed in a tapered shape, becoming thinner towards the tip. [Explanation of Symbols]
