Description

Technical Field

[0001] The present invention relates to a fish clamp for clamping the body of a fish and holding the fish at a certain position when removing a fishing needle during fishing. Background Art

[0002] As a fish clamp, there is a fish clamp described in Patent Document 1, for example. It is in the shape of a pliers, and the user (angler, etc.) can clamp the body of the fish by holding it with his hands. The fish clamp is in an open state at a certain angle with the help of a built-in spring when the lock for storage is released. When clamping the body of the fish, the user needs to overcome the spring force in the opening direction to hold it. Therefore, the user needs to continue to apply gripping force in the process of clamping the body of the fish. This causes fatigue to the user, so there is room for improvement in the fish clamp.

[0003] Patent Document 1: Japanese Registered Utility Model No. 3191183. Summary of the invention

[0004] Therefore, an object of the present invention is to provide a fish clamp that does not require a user to continuously apply force when clamping the body of a fish.

[0005] The fish clamp of the present invention comprises a clamping portion, a force-applying portion, and an operating portion. The clamping portion comprises a first clamping portion and a second clamping portion. The force-applying portion applies force to the first clamping portion and the second clamping portion in a direction of relative approach, and the operating portion moves the first clamping portion and the second clamping portion in a direction of relative separation.

[0006] According to this configuration, since the first clamping part and the second clamping part are urged in the direction of approaching each other by the urging part, the trunk of the fish can be clamped even if the user does not continue to apply force.

[0007] Furthermore, a locking mechanism that prevents the first clamping portion and the second clamping portion from moving in the separating direction may be provided.

[0008] According to this configuration, even when the fish held by the holding mechanism struggles, the holding mechanism is unlikely to come off from the trunk.

[0009] Furthermore, the locking mechanism can allow the first clamping portion and the second clamping portion to move in the separating direction by the operating portion.

[0010] According to this configuration, by placing the locking mechanism in the permission state, the fish can be easily released by the operation unit.

[0011] Furthermore, the operation portion may include a trigger that moves forward and backward in a direction intersecting the direction of separation.

[0012] According to this structure, the user can operate the trigger only with a finger, so the operation is easy.

[0013] Furthermore, the operation portion may include a pair of operation pieces facing each other, and the pair of operation pieces may be operated so as to approach and separate from each other.

[0014] According to this configuration, the operation direction as input and the approaching and separating movements of the first clamping portion and the second clamping portion as output are linked to each other, so the user can perform intuitive operation.

[0015] In addition, the first clamping portion and the second clamping portion are configured to rotate to perform the approach and separation, and the operating portion is operated in a direction that is point-symmetrical with respect to the point that serves as the center of the rotation, relative to the approach direction and the separation direction of the first clamping portion and the second clamping portion.

[0016] According to this configuration, the first clamping portion and the second clamping portion are configured to approach and separate from each other by rotation, and the operation portion can be configured in a direction symmetrical to the point of the rotation reference, so that the configuration can be simplified.

[0017] In addition, the aforementioned locking mechanism comprises a first locking component having a ratchet and a second locking component having an engaging claw engaged with the aforementioned ratchet. Through the combination of the aforementioned first locking component and the aforementioned second locking component, the aforementioned first clamping part and the aforementioned second clamping part can be allowed to move in the aforementioned approaching direction and movement in the aforementioned separating direction can be prevented.

[0018] According to this configuration, the first clamping portion and the second clamping portion can be prevented from separating by a general ratchet mechanism.

[0019] Effects of the Invention

[0020] According to the present invention, the first clamping part and the second clamping part are urged toward the approaching direction by the urging part, so the trunk of the fish can be clamped even if the user does not continuously apply force. Therefore, when clamping the trunk of the fish, the user does not need to continuously apply force. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Next, a fish clamp 1 according to an embodiment of the present invention will be described. First, a first embodiment will be described. The fish clamp 1 of this embodiment is as follows: Figure 1 to Figure 4 As shown in the figure, it is provided with a clamping mechanism 2, an action part 3, an operation part 4, a force application part 5, and a shell 6. In addition, regarding the expression of directions in the following description, regarding the front-back direction, the side closer to the fish when viewed from the user during use is set as "front", and the side farther from the fish is set as "rear". In addition, regarding the up-down-left-right directions, the Figure 1 to Figure 4 The direction is the direction when viewed from the user when in use in the state shown. In addition, this direction is only for the purpose of explaining each part, and the fish clamp 1 can of course also be used with the clamping mechanism 2 in a horizontal position, or with the clamping mechanism 2 located below the housing 6. The clamping mechanism 2, a part of the action part 3 (the first support part 31, the second support part 32), and a part of the operating part 4 (the trigger 42) are shown in FIG. Figure 1 and Figure 2 As shown, the housing 6 is exposed to the outside. The housing 6 is a hollow body made of resin, for example, and has a grip portion 61 on the outer periphery that can be gripped by a user.

[0027] The clamping mechanism 2 has a pair of two parts, namely, a first clamping part 21 and a second clamping part 22, which move toward each other in a manner of approaching and separating. The first clamping part 21 and the second clamping part 22 are configured to relatively approach and separate (move in a direction of approaching or separating from each other). More specifically, they are configured to approach and separate by rotating. Figure 1 The first clamping part 21 and the second clamping part 22 are close to each other, and the clamping mechanism part 2 is closed. Figure 2 The first clamping part 21 and the second clamping part 22 are separated, and the clamping mechanism part 2 is opened. The aforementioned rotation is based on an imaginary axis extending in the left-right direction behind the clamping mechanism part 2. Therefore, the clamping mechanism part 2 is opened in such a way that the gap between the first clamping part 21 and the second clamping part 22 becomes larger at the front than at the rear.

[0028] The first clamping portion 21 and the second clamping portion 22 have inner end portions 211 and 221 on the sides facing each other, respectively. The inner end portions 211 and 221 of the first clamping portion 21 and the second clamping portion 22 have a front-to-back length of more than 20 mm, respectively, and the whole or a part thereof contacts the trunk of the fish, thereby being able to hold the fish relative to the fish clamp 1. In the inner end portions 211 and 221 of the present embodiment, a plurality of triangular-shaped teeth are formed at the base portion which is slightly curved into a concave shape when viewed from the side, and the clamped fish can be prevented from escaping by the ends of the teeth biting into the trunk. The biting is mainly performed in a range having a length near the center of the front-to-back direction of the inner end portions 211 and 221, and can also be performed in a range at the ends in the front-to-back direction. The teeth of the present embodiment are in the shape of a right triangle with the front side being the hypotenuse. Therefore, it is possible to effectively prevent the trunk of the fish from escaping forward. In addition, in the present embodiment, a plurality of teeth are formed in two rows on the left and right sides in each clamping portion 21 and 22 (see Figure 2 ), but the configuration of the teeth is not particularly limited. The front-to-back length and curvature of the inner ends 211 and 221 of the first clamping portion 21 and the second clamping portion 22 can be appropriately set corresponding to the size of the fish to be clamped and the shape (roundness) of the trunk.

[0029] The action part 3 is connected to the first clamping part 21 and the second clamping part 22, respectively, and is operated by operating the operation part 4 and applying force by the force applying part 5 to make the first clamping part 21 and the second clamping part 22 approach and leave each other. The action part 3 is connected to the rear of the first clamping part 21. The connection is a fixed connection (the same is true for the second clamping part 22). The action part 3 is provided with a plurality of support shafts 34, 37 and a plurality of connecting shafts 35, 36, 38 for defining the action range of each of the first supporting part 31, the second supporting part 32, and the connecting rod part 33 and the aforementioned parts.

[0030] The first support portion 31 and the second support portion 32 are elongated plate-like bodies. The front end portion of the first support portion 31 is located above the second support portion 32. The first support portion 31 is shaped to bend upward in the front-to-back direction, and the first clamping portion 21 is fixed to the front end portion. The second support portion 32 is shaped to bend downward in the front-to-back direction, and the second clamping portion 22 is fixed to the front end portion. The first support portion 31 and the second support portion 32 intersect each other up and down in the middle of the front-to-back direction (the position of the first connecting shaft 35).

[0031] A first support shaft 34 is provided at the upper front portion of the housing 6. The first support shaft 34 extends in the left-right direction. The rear end portion of the second support portion 32 is rotatably supported on the first support shaft 34. The second support portion 32 rotates around the first support shaft 34. In the closed state of the clamping mechanism portion 2, the front end portion of the second support portion 32 is located at the front side and the lower side relative to the first support shaft 34.

[0032] The first support portion 31 and the second support portion 32 are connected to each other by means of the 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 shell 6 and can move relative to the shell 6. The first connecting shaft 35 rotates integrally with the second support portion 32 around the first support shaft 34. The first connecting shaft 35 is located between the rear end and the front end of the second support portion 32, and 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. In the closed state of the clamping mechanism portion 2, the first connecting shaft 35 is located at the front and lower side relative to the first support shaft 34. The first support portion 31 is centered around the first connecting shaft 35. Figure 3 , Figure 4 Open while turning clockwise.

[0033] The connecting rod portion 33 is an elongated plate-shaped body rotatably connected to the first supporting portion 31 and the operating portion 4, respectively. The first supporting portion 31 and the connecting rod portion 33 are connected to each other by means of a second connecting shaft 36. The rear end portion of the first supporting portion 31 and the front end portion of the connecting rod portion 33 are rotatably connected by means of the second connecting shaft 36. The second connecting shaft 36 is not fixed to the shell 6 and can move relative to the shell 6. The second connecting shaft 36 extends in the left-right direction. The second connecting shaft 36 is approximately the same position as the first support shaft 34 in the front-to-back direction and is located below the first support shaft 34. The second connecting shaft 36 is located at the rear and lower side compared to the first connecting shaft 35 in the closed state of the clamping mechanism portion 2.

[0034] A second support shaft 37 is provided at the rear of the shell 6. The second support shaft 37 extends in the left-right direction. The second support shaft 37 is located at the rear and lower side compared to the first support shaft 34. The connecting rod portion 33 is long in the front-to-back direction. The rear end of the connecting rod portion 33 is rotatably supported on the second support shaft 37. The connecting rod portion 33 rotates in the vertical direction around the second support shaft 37. The connecting rod portion 33 rotates from the closed state to the open state around the second support shaft 37. Figure 3 , Figure 4 Rotate counterclockwise.

[0035] The operating portion 4 can slide relative to the housing 6. The sliding direction of the operating portion 4 is the front-to-back direction. The operating portion 4 slides in a direction approaching and moving away from the first support portion 31 and the second support portion 32. The operating portion 4 includes a slider 41 that is long in the front-to-back 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 extending in the front-to-back direction (see Figure 4 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.

[0036] The trigger 42 moves forward and backward in a direction intersecting with the direction in which the first clamping portion 21 and the second clamping portion 22 are separated. The user hooks the front surface of the trigger 42 with a finger and performs a pulling operation. The trigger 42 can be pulled from the initial position in a direction intersecting with the moving direction of a pair of clamping portions (the first clamping portion 21, the second clamping portion 22). The user can operate the trigger only with a finger, so the operation of the operating portion is easy. For example, the trigger 42 is hooked with the index finger of the user's hand holding the grip portion 61. The shell 6 has a finger insertion hole 43 that passes through in the left-right direction at the lower rear side. The trigger 42 protrudes from the upper side to the finger insertion hole 43. The shell 6 has a trigger guard 44 on three sides surrounding the finger insertion hole 43, namely, the front, bottom, and rear.

[0037] The force-applying portion 5 uses, for example, a coil spring (compression spring). The force-applying portion 5 applies force to the operating portion 4 in the forward direction. This force application is always performed. Therefore, the trigger 42 is applied to the aforementioned initial position, and if the user's finger leaves the trigger 42, the trigger 42 returns to the aforementioned initial position. The force-applying portion 5 applies force to the operating portion 4 toward the front side, whereby the first clamping portion 21 connected to the first supporting portion 31 and the second clamping portion 22 connected to the second supporting portion 32 are respectively applied to the closing side. That is, the force-applying portion 5 applies force in the direction in which the first clamping portion 21 and the second clamping portion 22 approach each other. With the help of the force-applying portion 5, force is applied in the direction in which the first clamping portion 21 and the second clamping portion 22 approach each other (the closing direction of the clamping mechanism portion 2), so even if the user does not continue to apply force, the trunk of the fish can be clamped with the help of the clamping mechanism portion 2.

[0038] The operating portion 4 and the link portion 33 are connected to each other by means of the third connecting shaft 38. The third connecting shaft 38 is fixed to the front end portion 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 shell 6 has a pair of left and right guide grooves 62 that extend in the front-back direction respectively. 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-back direction while being guided by the left and right guide grooves 62. The third connecting shaft 38 slides in the guide groove, thereby, the operating portion 4 slides back and forth. The third connecting shaft 38 and the slider 41 are integrated, so the sliding of the third connecting shaft 38 and the sliding of the operating portion 4 are in a linked relationship.

[0039] A long hole 331 is formed in the middle of the connecting rod portion 33 in the front-to-back direction. The third connecting shaft 38 is located in the long hole 331. The third connecting shaft 38 moves along the long hole 331. The long hole 331 extends in a direction inclined relative to the front-to-back direction. The front end of the long hole 331 is located below the rear end. If the third connecting shaft 38 slides to the rear side as the operating portion 4 slides to the rear side, the third connecting shaft 38 causes the connecting rod portion 33 to move about the second support shaft 37. Figure 3 , Figure 4Rotate counterclockwise.

[0040] By pulling the trigger 42 of the operating portion 4 toward the rear, the first clamping portion 21 connected to the first supporting portion 31 and the second clamping portion 22 connected to the second supporting portion 32 are moved from the first supporting portion 31 to the second supporting portion 32. Figure 1 and Figure 3 The closed state shown opens to Figure 2 and Figure 4 That is, the operation portion moves the first clamping portion 21 and the second clamping portion 22 in a direction away from each other.

[0041] The fish clamp 1 is provided with a locking mechanism 7 for preventing the first clamping portion 21 and the second clamping portion 22 from moving in the direction of separation. In the present embodiment, a cam mechanism composed of an operating portion 4 (more specifically, the third connecting shaft 38) and a connecting rod portion 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 that it can only slide in the front-back direction. Furthermore, the force-applying portion 5 applies force to the slider 41 forward. Under such circumstances, the sliding movement of the slider 41 caused by the pulling operation of the trigger 42 by the user is transmitted to the clamping mechanism portion 2 via the operating portion 3. However, when an external force caused by the struggle of the fish or the like is applied to the clamping mechanism portion 2 in the opening direction, the external force is transmitted from the first clamping portion 21 to the connecting rod portion 33 via the second support shaft 37. The front portion of the connecting rod portion 33 to which the external force is transmitted in this way intends to move downward. However, since the third connecting shaft 38 is hooked on the long hole 331 provided in the link portion 33, the link portion 33 is prevented from moving downward, thereby preventing the clamping mechanism portion 2 from opening against the user's intention due to external force.

[0042] With the locking mechanism 7 functioning in this way, even if the fish in the state of being clamped by the clamping mechanism part 2 struggles, the clamping mechanism part 2 is not easy to be separated from the trunk. In addition, the locking mechanism 7 allows the first clamping part 21 and the second clamping part 22 to move in the direction of separation by the operating part 4. By setting the locking mechanism 7 to the permission state, the fish can be easily released from the fish clamp 1 by the user operating the operating part 4.

[0043] In the fish clamp 1 constructed as described above, it is not necessary to move the first clamping part 21 and the second clamping part 22 to a predetermined part of the fish, and the fish can be clamped by simply moving the clamping mechanism part 2 in the open state to a part such as the trunk that is easy to clamp and removing the hand force.

[0044] An embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment, and various changes can be made without departing from the gist of the present invention.

[0045] For example, in the first embodiment, the opening operation of the clamping mechanism 2 is performed in response to the trigger, but it is also possible to configure the clamping mechanism 2 to be opened in response to the gripping operation of the user's hand, such as pliers or tweezers. The second embodiment is described below. In addition, the same names and reference numerals are used for the parts that are functionally common to the first embodiment.

[0046] Figure 5 (A)(B) briefly shows the structure of the second embodiment. The fish clamp 1 of the second embodiment is composed of a pair of movable pieces 81, 82. The operating portion 4 has a pair of operating pieces 45, 46 facing each other. Each operating piece 45, 46 is the rear portion of each movable piece 81, 82. The clamping mechanism portion 2 is the front portion of the two movable pieces 81, 82. That is, the clamping mechanism portion 2 is continuously arranged in front of the two operating pieces 45, 46. The first clamping portion 21 is arranged at a forward extension position of the operating piece 45 on one side of the pair of operating pieces 45, 46, and the second clamping portion 22 is arranged at a forward extension position of the operating piece 46 on the other side.

[0047] The pair of operating pieces 45 and 46 are operated by the user by grasping them with their hands to move them closer and further away. In the second embodiment, the operation direction of the operating portion 4 as input is associated with the movement of the first clamping portion 21 and the second clamping portion 22 as output. Figure 5 As shown in (B), when the pair of operating pieces 45 and 46 are brought close to each other by the user's operation, the first clamping portion 21 and the second clamping portion 22 are separated. Figure 5 As shown in (A), when the pair of operation pieces 45 and 46 are restored to the separated state by the urging force of the urging part 5, the first clamping part 21 and the second clamping part 22 are brought close to each other. Therefore, the user can perform intuitive operation.

[0048] A spring as a biasing portion 5 is provided between the pair of operating pieces 45 and 46. The spring is, for example, a coil spring (compression spring). Figure 5 As shown in (A), a force is always applied to the pair of operating pieces 45 and 46 in the closing direction, and accordingly, the clamping mechanism part 2 is in a closed state.

[0049] The first clamping portion 21 and the second clamping portion 22 are as follows Figure 5 As shown in (A) and (B), the operation portion 4 is configured to rotate to approach and separate. The operation portion 4 is operated in a direction symmetrical with respect to the approach direction and separation direction of the first clamping portion 21 and the second clamping portion 22, with reference to the point C which is the center of the aforementioned rotation. Specifically, when the user holds the operation portion 4, as shown in FIG. Figure 5 As shown in (B), the first clamping part 21 and the second clamping part 22 are separated, and if the user relaxes the force of holding the operating part 4, Figure 5As shown in (A), the first clamping part 21 and the second clamping part 22 are close to each other. In this way, the first clamping part 21 and the second clamping part 22 can be configured so that the operation part 4 is symmetrical in the direction of the rotation reference point, so that the structure can be simplified.

[0050] The locking mechanism 7 includes a first locking component 71 having a ratchet 711 composed of a plurality of teeth, and a second locking component 72 having an engaging claw 721 that engages with the teeth of the ratchet 711. The plurality of teeth constituting the ratchet 711 in the first locking component 71 are each in a unidirectionally inclined triangular shape as shown in the figure, and are arranged around the entire circumference of the movable piece 81 on one side. The second locking component 72 is arranged to be rotatable within a predetermined range relative to the movable piece 81 on one side. The engaging claw 721 of the second locking component 72 is pressed relative to the ratchet 711 of the first locking component 71 by a claw spring 73. Therefore, the movement of the ratchet 711 relative to the engaging claw 721 in one direction ( Figure 5 (B) is allowed in the counterclockwise direction, but in the other direction ( Figure 5 (B) is blocked in the clockwise direction. The engagement state of the engagement claw 721 relative to the ratchet wheel 711 is as follows: Figure 5 As shown in (A), the second locking member 72 can be released by pushing the rear portion thereof into the movable piece 81 on one side.

[0051] In the second embodiment, the first clamping portion 21 and the second clamping portion 22 are allowed to move in the direction of approaching and are prevented from moving in the direction of separation by the combination of the first locking member 71 and the second locking member 72. With this structure, the first clamping portion 21 and the second clamping portion 22 can be prevented from separating by using a general ratchet mechanism. The above is the description of the second embodiment.

[0052] In addition, as a possible change in the embodiment, the clamping mechanism part 2 can be dedicated to clamping the body of the fish, so it can also be constructed so that in the closed state, the front ends of the first clamping part 21 and the second clamping part 22 are not in close contact with each other, and a gap is maintained between the first clamping part 21 and the second clamping part 22 in the closed state.

[0053] In addition, in the first and second embodiments, both the first clamping portion 21 and the second clamping portion 22 are configured to move relative to the shell 6. However, the first clamping portion 21 and the second clamping portion 22 may be relatively close to and away from each other. Therefore, for example, it is also possible to configure that one of the first clamping portion 21 and the second clamping portion 22 is fixedly provided relative to the shell 6, etc., and only the other one moves relative to the shell 6, etc.

[0054] In addition, in the first and second embodiments, the inner ends 211 and 221 of the first clamping portion 21 and the second clamping portion 22 extend slightly curved in the front-back direction. However, the present invention is not limited thereto, and the inner ends 211 and 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 according to the shape of the trunk of the fish to be clamped (e.g., a large fish, a small fish, a flat trunk, or a rounded trunk).

[0055] In addition, the clamping mechanism 2 of the first and second embodiments is configured to open in a manner that the interval between the first clamping portion 21 and the second clamping portion 22 becomes larger at the front than at the rear. However, the present invention is not limited thereto, and may be configured to open in a state where the interval between the first clamping portion 21 and the second clamping portion 22 is equal at the front and rear (i.e., the inner ends 211 and 221 are parallel). Such opening and closing can be achieved by adding a connecting rod or a gear to the clamping mechanism 2 or the operating portion 3.

[0056] Furthermore, in the first embodiment, the clamping mechanism portion 2 and the operating portion 3 are configured as separate bodies and the two are connected, but the two may be configured as a single body and inseparable.
