Description

[Technical field]

[0001] The present invention relates to a fish clamp for holding a fish in a fixed position by clamping its body when, for example, removing a fishhook during fishing. [Background technology]

[0002] An example of a fish clamp is described in Patent Document 1. This is in the form of tongs, and a user (such as an angler) can grip the body of a fish by holding it in their hands. When this fish clamp is in the unlocked state used for storage, a built-in spring opens it at a certain angle. When clamping the body of a fish, the user needs to grip it against the spring force in the opening direction. For this reason, there is room for improvement in terms of ease of operation.

[0003] [Patent Document 1] Registered Utility Model No. 3191183 Summary of the Invention [Problem to be solved by the invention]

[0004] Therefore, an object of the present invention is to provide a fish clamp that is easy to operate. [Means for solving the problem]

[0005] The present invention is a fish clamp comprising a pair of clamping parts and an operating part for moving the pair of clamping parts toward or away from each other, the operating part having a trigger that can be pulled from an initial position in a direction intersecting the movement direction of the pair of clamping parts.

[0006] According to this configuration, the user can operate the trigger using only his / her finger, making operation easy.

[0007] The trigger may further include a biasing portion that biases the pair of clamping portions in either the approaching direction or the separating direction, and the trigger may be biased toward the initial position by the biasing force of the biasing portion.

[0008] According to this configuration, the trigger is held in the initial position by the biasing portion.

[0009] The device may further include a locking mechanism that prevents the pair of clamping portions from moving away from each other.

[0010] With this configuration, even if the fish held by the clamping parts struggles, the clamping parts are unlikely to come off from the body. Effect of the Invention

[0011] According to the present invention, the user can operate the trigger with just his / her finger, which makes operation easy. Therefore, a fish clamp that can be easily operated can be provided. [Brief description of the drawings]

[Figure 4] FIG. 2 is a vertical cross-sectional view showing the fish clamp (in an open state). DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Next, a fish clamping device 1 according to an embodiment of the present invention will be described. As shown in Figs. 1 to 4, the fish clamping device 1 of this embodiment includes a clamping mechanism 2, an operating unit 3, an operating unit 4, a biasing unit 5, and a case 6. In the following description, the front-rear direction refers to the side closer to the fish as seen by the user during use as the "front" and the side farther from the fish as the "rear". The up-down and left-right directions are also the directions as seen by the user during use in the state shown in Figs. 1 to 4. Note that these directions are merely for the purpose of describing each part, and it is of course possible to use the fish clamping device 1 with the clamping mechanism 2 laid down on its side or positioned lower than the case 6. The clamping mechanism 2, a part of the operating unit 3 (first support unit 31, second support unit 32), and a part of the operating unit 4 (trigger 42) are exposed to the outside of the case 6 as shown in Figs. 1 and 2. The case 6 is a hollow body made of, for example, resin, and has a grip portion 61 on its outer periphery that can be grasped by the user.

[0014] The clamping mechanism 2 has a pair of first and second clamping parts 21 and 22 that face each other and move toward and away from each other. The first and second clamping parts 21 and 22 are configured to move toward and away from each other (move toward or away from each other). More specifically, they are configured to move toward and away from each other by rotating. FIG. 1 shows a state in which the clamping mechanism 2 is closed as the first and second clamping parts 21 and 22 move toward each other. FIG. 2 shows a state in which the clamping mechanism 2 is open as the first and second clamping parts 21 and 22 move away from each other. The rotation is performed based on a virtual axis that extends in the left-right direction at the rear of the clamping mechanism 2. Therefore, the clamping mechanism 2 opens so that the distance between the first and second clamping parts 21 and 22 is larger at the front than at the rear.

[0015] Each of the first clamping portion 21 and the second clamping portion 22 has an inner end 211, 221 on the side where they face each other. The inner end 211, 221 of the first clamping portion 21 and the second clamping portion 22 each has a front-rear length of 20 mm or more, and the whole or part of the inner end 211, 221 can be held by the fish clamping tool 1 by contacting the body of the fish. The inner end 211, 221 of this embodiment has a base that is slightly concavely curved in a side view, and the tips of the teeth bite into the body to prevent the clamped fish from shifting. This biting is mainly performed in a range that is long near the center in the front-rear direction of the inner end 211, 221, and may also be performed in a range of the front-rear direction ends. The teeth of this embodiment are in the shape of a right triangle with the hypotenuse at the front. Therefore, the body of the fish can be effectively prevented from shifting forward. In this embodiment, each of the clamping parts 21, 22 has a plurality of teeth in two rows, one on the left and one on the right (see FIG. 2), but the arrangement of the teeth is not particularly limited. The front-rear length and curvature of the inner ends 211, 221 of the first clamping part 21 and the second clamping part 22 can be appropriately set according to the size of the fish to be clamped and the shape (roundness) of the body.

[0016] The operating unit 3 is connected to each of the first clamping unit 21 and the second clamping unit 22, and operates by operating the operating unit 4 and by the biasing force of the biasing unit 5 to move the first clamping unit 21 and the second clamping unit 22 closer to and away from each other. The operating unit 3 is connected to the rear of the first clamping unit 21. The connection is fixed (the same applies to the second clamping unit 22). The operating unit 3 is provided with each of a first support unit 31, a second support unit 32, and a link unit 33, as well as a plurality of support shafts 34, 37 and a plurality of connecting shafts 35, 36, 38 for defining the operating ranges of each of the above units.

[0017] The first support part 31 and the second support part 32 are elongated plate-like bodies. The front end part of the first support part 31 is located above the second support part 32. The first support part 31 is curved upward along the front-rear direction, and the first clamping part 21 is fixed to the front end part. The second support part 32 is curved downward along the front-rear direction, and the second clamping part 22 is fixed to the front end part. The first support part 31 and the second support part 32 cross each other vertically midway in the front-rear direction (at the position of the first connecting shaft 35).

[0018] A first support shaft 34 is provided on the upper front part of the case 6. The first support shaft 34 extends in the left-right direction. The rear end part of the second support part 32 is rotatably supported by the first support shaft 34. The second support part 32 rotates around the first support shaft 34. When the clamping mechanism part 2 is in the closed state, the front end part of the second support part 32 is located in front of and below the first support shaft 34.

[0019] The first support portion 31 and the second support portion 32 are connected to each other by a first connecting shaft 35. The first connecting shaft 35 extends in the left-right direction. The first support portion 31 is rotatably connected to the second support portion 32 via the first connecting shaft 35, and the first support portion 31 rotates around the first connecting shaft 35. The first connecting shaft 35 is not fixed to the case 6 and can move relative to the case 6. The first connecting shaft 35 rotates around the first support shaft 34 together with the second support portion 32. The first connecting shaft 35 is located between the rear end and the front end of the second support portion 32, and is located between the first support shaft 34 and the front end of the second support portion 32. The first connecting shaft 35 is located between the rear end and the front end of the first support portion 31. When the clamping mechanism portion 2 is in the closed state, the first connecting shaft 35 is located on the front side and below the first support shaft 34. The first support portion 31 opens while rotating clockwise on FIGS. 3 and 4 about the first connecting shaft 35.

[0020] The link portion 33 is a long and narrow plate-like body rotatably connected to the first support portion 31 and the operating portion 4, respectively. The first support portion 31 and the link portion 33 are connected to each other by a second connecting shaft 36. The rear end portion of the first support portion 31 and the front end portion of the link portion 33 are rotatably connected by the second connecting shaft 36. The second connecting shaft 36 is not fixed to the case 6 and can move relative to the case 6. The second connecting shaft 36 extends in the left-right direction. The second connecting shaft 36 is located at approximately the same position as the first support shaft 34 in the front-rear direction and is located below the first support shaft 34. The second connecting shaft 36 is located rearward and below the first connecting shaft 35 when the clamping mechanism portion 2 is in the closed state.

[0021] A second support shaft 37 is provided at the rear of the case 6. The second support shaft 37 extends in the left-right direction. The second support shaft 37 is located rearward and below the first support shaft 34. The link portion 33 is long in the front-rear direction. The rear end of the link portion 33 is rotatably supported by the second support shaft 37. The link portion 33 rotates in the up-down direction about the second support shaft 37. The link portion 33 rotates counterclockwise in Figures 3 and 4 about the second support shaft 37 as the clamping mechanism portion 2 changes from the closed state to the open state.

[0022] The operating unit 4 is slidable relative to the case 6. The sliding direction of the operating unit 4 is the front-rear direction. The operating unit 4 slides in a direction toward and away from the first support unit 31 and the second support unit 32. The operating unit 4 has a slider 41 that is long in the front-rear direction, and a trigger 42 that protrudes downward from the rear lower surface of the slider 41. The slider 41 has a guide hole 411 (see FIG. 4) that extends in the front-rear direction. The guide hole 411 is a through hole that penetrates the slider 41 in the left-right direction. The second support shaft 37 penetrates the guide hole 411.

[0023] The trigger 42 advances and retreats in a direction intersecting the direction in which the first clamping portion 21 and the second clamping portion 22 move away from each other. The user hooks a finger on the front surface of the trigger 42 and pulls it. The trigger 42 can be pulled from the initial position in a direction intersecting the moving direction of the pair of clamping portions (the first clamping portion 21 and the second clamping portion 22). The user can operate the trigger with only his or her finger, so that the operation of the operation portion is easy. For example, the index finger of the user's hand gripping the grip portion 61 is hooked on the trigger 42. The case 6 has a finger insertion hole 43 penetrating in the left-right direction at the lower rear side. The trigger 42 protrudes from the upper side into the finger insertion hole 43. The case 6 has a trigger guard 44 that surrounds the finger insertion hole 43 on three sides, the front, the lower, and the rear.

[0024] The biasing unit 5 is, for example, a coil spring (compression spring). The biasing unit 5 biases the operation unit 4 forward. This biasing is always performed. Therefore, the trigger 42 is biased toward the initial position, and when the user releases his / her finger from the trigger 42, the trigger 42 returns to the initial position. When the biasing unit 5 biases the operation unit 4 forward, the first clamping unit 21 connected to the first support unit 31 and the second clamping unit 22 connected to the second support unit 32 are each biased toward the closing side. In other words, the biasing unit 5 biases the first clamping unit 21 and the second clamping unit 22 in a direction to approach each other. Since the biasing unit 5 biases the first clamping unit 21 and the second clamping unit 22 in a direction to approach each other (closing direction of the clamping mechanism unit 2), the clamping mechanism unit 2 can clamp the body of the fish without the user having to continue applying force.

[0025] The operation unit 4 and the link unit 33 are connected to each other by a third connecting shaft 38. The third connecting shaft 38 is fixed to the front end of the slider 41. The third connecting shaft 38 extends in the left-right direction. The third connecting shaft 38 penetrates the slider 41 in the left-right direction. The case 6 is a pair of left and right cases, each of which has a guide groove 62 extending in the front-rear direction. Both ends of the third connecting shaft 38 are located in the left and right guide grooves 62, respectively, and the third connecting shaft 38 slides in the front-rear direction while being guided by the left and right guide grooves 62. The third connecting shaft 38 slides in the guide groove, causing the operation unit 4 to slide forward and backward. Since the third connecting shaft 38 is integral with the slider 41, the sliding of the third connecting shaft 38 and the sliding of the operation unit 4 are in an interlocking relationship.

[0026] A long hole 331 is formed in the middle of the link part 33 in the front-rear direction. The third connecting shaft 38 is positioned in this long hole 331. The third connecting shaft 38 moves along the long hole 331. The long hole 331 extends in a direction inclined with respect to the front-rear direction. The front end of the long hole 331 is positioned lower than the rear end. When the third connecting shaft 38 slides rearward as the operating part 4 slides rearward, the third connecting shaft 38 rotates the link part 33 counterclockwise in Figures 3 and 4 around the second support shaft 37.

[0027] The first clamping portion 21 connected to the first support portion 31 and the second clamping portion 22 connected to the second support portion 32 open from the closed state shown in Figures 1 and 3 to the open state shown in Figures 2 and 4 by pulling the trigger 42 of the operating portion 4 rearward. In other words, the operating portion moves the first clamping portion 21 and the second clamping portion 22 in directions in which they move apart relatively.

[0028] The fish clamping tool 1 includes a locking mechanism 7 that prevents the first clamping part 21 and the second clamping part 22 from moving in a direction away from each other. In this embodiment, a cam mechanism formed by the operating part 4 (more specifically, the third connecting shaft 38) and the link part 33 (more specifically, the long hole 331) functions as the locking mechanism 7. The third connecting shaft 38 is fixed to the slider 41, so it can only slide in the forward and backward directions. Furthermore, the biasing part 5 biases the slider 41 forward. Under such circumstances, the sliding movement of the slider 41 caused by the user pulling the trigger 42 is transmitted to the clamping mechanism part 2 via the operating part 3. However, when an external force caused by a fish struggling or the like applies a force in the opening direction to the clamping mechanism part 2, this external force is transmitted from the first clamping part 21 to the link part 33 via the second support shaft 37. The front part of the link part 33 to which the external force is transmitted in this manner tries to move downward. However, since the third connecting shaft 38 gets caught in the long hole 331 provided in the link part 33, the downward movement of the link part 33 is prevented and the link part 33 does not move, so that the clamping mechanism part 2 is prevented from opening unintentionally by the user due to an external force.

[0029] Locking mechanism 7 that functions in this manner makes it difficult for clamping mechanism 2 to come off from the body even if the fish held by clamping mechanism 2 struggles. Locking mechanism 7 also permits first clamping portion 21 and second clamping portion 22 to be moved away from each other by operating portion 4. By setting locking mechanism 7 to the permitting state, the fish can be easily released from fish clamp 1 by operating operating portion 4 by the user.

[0030] In the fish clamping tool 1 configured as above, the clamping mechanism 2 can be operated by the trigger 42, so that the fish clamping tool 1 is easy to handle and the operability is improved significantly.

[0031] Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the gist of the present invention.

[0032] For example, in the above embodiment, both the first clamping portion 21 and the second clamping portion 22 are configured to move relative to the case 6. However, the first clamping portion 21 and the second clamping portion 22 may move relatively closer to and away from each other. Therefore, for example, one of the first clamping portion 21 and the second clamping portion 22 may be fixedly provided relative to the case 6 or the like, and only the other may move relative to the case 6 or the like.

[0033] In the above embodiment, the inner ends 211, 221 of the first clamping portion 21 and the second clamping portion 22 extend with a slight curve in the front-rear direction. However, this is not limited to this, and the inner ends 211, 221 of one or both of the first clamping portion 21 and the second clamping portion 22 may be straight. The degree of curvature can be appropriately set depending on the shape of the body of the fish expected to be clamped (for example, whether it is a large fish or a small fish, whether it has a flat body or a rounded body, etc.).

[0034] In addition, the clamping mechanism 2 in the above embodiment is configured to open so that the distance between the first clamping portion 21 and the second clamping portion 22 is larger at the front than at the rear. However, this is not limited to this, and the clamping mechanism 2 may be configured to open so that the distance between the first clamping portion 21 and the second clamping portion 22 remains equal at the front and rear (i.e., the inner ends 211, 221 remain parallel). Such opening and closing can be achieved by adding a link or gear to the clamping mechanism 2 or the operating portion 3.

[0035] In the above embodiment, the biasing unit 5 is configured to bias the clamping mechanism 2 or the operating unit 3 in a direction in which the pair of clamping units 21, 22 approach each other (the closing direction of the clamping mechanism 2). However, the biasing unit 5 may be configured to bias the pair of clamping units 21, 22 in a direction in which the pair of clamping units 21, 22 move away from each other (the opening direction of the clamping mechanism 2).

[0036] In addition, in the above embodiment, the clamping mechanism unit 2 is configured separately from the operating unit 3 and the two are connected to each other, but the two may also be configured as an integral, inseparable unit. [Explanation of symbols]
