Description

  The present invention relates to a fish gripper that picks up the mouth of a fish when the caught fish is taken from the water surface.

  As prior arts related to the present invention, Patent Documents 1 to 5 disclose fish grippers having a crocodile mouth that is opened and closed by a trigger operation at one end of a handle. This fish grabber can grab the mouth of the fish (mandible) with the alligator mouth and hang the fish in the dangling state in this state. Used for so-called landing. Moreover, after taking in the fish, the needle can be removed while the fish is suspended. During this time, since the angler does not touch the fish directly, even fish with sharp teeth or fins or fish with poison can be taken in and removed safely. In addition, because the damage to the fish is less than the capture using a hand grip or a tamo-net, it is possible to escape the fish you caught in a healthy state, and it is suitable for use in game fishing and sport fishing that perform catch and release .

  However, the ones in Patent Documents 1 and 2 have a small handle (grip part) and a short distance from the hand to the crocodile mouth, so when the fish is large or violent, or a large lure is used. When it is, it is dangerous because fish and lure needles may come into contact with the hands.

  On the other hand, the thing of patent documents 3-5 is equipped with the grip part (2) which incorporated the scale in the clamping part (3) equipped with the opening and closing mechanism of the alligator mouth, and the part which uses this grip part (2) as a handle The distance from the hand to the crocodile is longer than that of Patent Documents 1 and 2, but the safety is increased. However, the structure is complicated because the clamping mechanism (2) is combined with a measuring mechanism.

  In addition, if the distance (reach) from a handle to a crocodile mouth is long, the risk that a hand will contact a fish or a fishhook will decrease, but it will become difficult to handle conversely. For this reason, it is preferable that the length of reach can be changed according to the contents of fishing, such as the kind and size of a target fish. However, since Patent Documents 1 to 5 do not have such a length adjustment function, Patent Documents 1 and 2 need to be used for small to medium sizes, and Patent Documents 3 to 5 must be used for medium to large sizes. . In addition, there is no fish gripper having a length adjusting function in the market, and a long size and a short size are selected according to the contents of fishing.

  On the other hand, some caught fish have their mouths closed by swallowing a needle, etc., and it is not possible to use a fish grabber as it is, so it is necessary to pry the mouth open or pry the mouth into the mouth. Documents 1-5 do not have such a function.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a fish grabber that can be appropriately adjusted in length according to the contents of fishing. It is also an object of the present invention to provide a fish grabber that can be used even when the fish mouth is closed.

  In order to achieve the above-described object, in the present invention, a grip in which two plates are opposed to each other via a spacer, and a toolbar in which the grip and one end are rotatably connected so as to be retractable between the two plates. And a lock mechanism that can regulate the rotation of the tool bar in the folded state in which the tool bar is stored in the grip and the open state in which the tool bar is opened in a line, and a normally closed alligator provided at the open end of the tool bar. A mouth and an actuator capable of opening the alligator mouth in an interlocked manner within the alligator mouth and the tool bar, and the actuator includes two finger hooks corresponding to the folded state and the open state, respectively. The means of projecting in the opposite direction from each of the side edges in the longitudinal direction was used. According to the said means, a full length becomes long in the open state, and it can grasp a fish more safely. On the other hand, in the folded state, the overall length is shortened, handling is easy, and it is convenient for carrying and storage.

  The actuator is an operator that is operated directly with a finger to open the mouth of the normally closed alligator, and does not specify a specific operation method, but preferably the finger-hanging portion is slid along the longitudinal direction of the tool bar. The alligator is connected to the alligator mouth by a link that can convert the sliding movement of the actuator to the opening and closing movement of the alligator mouth. The sliding actuator makes it easy to operate the finger-hanging part like a pistol trigger (trigger), and secures a sufficient sliding distance with respect to the long tool bar. Large opening angle of the alligator can be secured.

  The alligator includes a fixed claw fixed to the open end of the tool bar and a movable claw pivotally supported on the open end. The movable claw is connected to the actuator and the tool bar. According to this means, since only one of the claws is rotated, the mouth opening / closing structure is simpler than the rotation of the two claws. Furthermore, by providing a sharply tapered spatula portion on the outer periphery of the tip of at least one of the fixed claw and the movable claw, the mouth can be opened by the spatula portion when the fish mouth is closed.

  On the other hand, the lock mechanism includes a knob provided on the surface of one plate of the grip so as to be rotatable, a lock pin projecting from the knob through the one plate toward the tool bar, and an open state at one end edge of the tool bar. Since the lock pin is formed at two positions corresponding to the folded state, the lock pin can be easily released by operating the knob with the other hand while holding the grip with one hand. Also, by changing the knob to the other grip plate, it can be changed to right-handed or left-handed.

  Furthermore, the opening angle between the grip and the tool bar can be set to a maximum of 180 degrees. However, if the opening state is maintained such that the tool bar is inclined with respect to the grip by the lock mechanism, the actuator can be easily operated.

  According to the present invention, since the overall length can be adjusted by opening or folding the grip, it is possible to grip the fish mouth safely and easily in response to fishing of any content, such as small to large fish. In addition, since the grip opening and closing is switched by a knob-type locking mechanism, the operation is easy, and if the knob is replaced with the grip plate on the opposite side, the right-handed one can be changed to the left-handed one, which is excellent in practicality. Furthermore, by restricting the maximum opening angle so that the tool bar is inclined with respect to the grip by the lock mechanism, it is possible to make the fish gripper easy to operate the actuator. Furthermore, since two finger-hook portions of the actuator are provided corresponding to the open state and the half-folded state, the mouth can be reliably opened and closed in each state. In addition, since the spatula part is provided on one nail of the alligator mouth, this claw can be put into the fish mouth at the same time while opening the closed mouth of the fish, and the fish mouth can be grasped more easily and reliably. .

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a fish grasper according to a first embodiment of the present invention. In the figure, 1 is a tool bar, 2 is a normally closed alligator provided at one end of the tool bar 1, and 3 is This is a trigger (trigger) type actuator that opens the alligator 2. The alligator 2 is composed of a pair of hook-like claws 2a and 2b that sandwich a fish mouth (mandible), one of which is a fixed claw, and the other claw 2b is connected via a link mechanism built in the tool bar 1. The movable claw 2b connected to the actuator 3 is energized by the elastic force of the elastic spring provided in the link mechanism, so that the movable claw 2b is brought into elastic contact with the fixed claw 2a in a normal state and the wrinkle 2 is closed. ing. Then, the actuator 3 is slid to the rear end side (grip side, which will be described later) along the longitudinal direction of the tool bar 1 against the elastic force of the elastic spring, thereby moving the movable claw 2b to the outside via the link mechanism. And the mouth 2 is opened. The alligator 2 is one in which one claw is put into the mouth of the fish and its lower jaw is sandwiched between the inside and outside of the mouth by the claws 2a, 2b, and it is arbitrary which claw 2a, 2b is put in the mouth of the fish. In this embodiment, a sharply tapered spatula portion 2a ′ is provided on the outer periphery of the distal end of the fixed claw 2a. If the fish mouth is closed, the spatula portion 2a ′ is inserted into the closed mouth. The fish mouth can be opened by turning, and the fixed claw 2a can be put into the fish mouth.

  Next, reference numeral 4 denotes a grip functioning as a grip portion provided rotatably at the other end of the tool bar 1, and the tool bar 1 is extended from the grip 4 shown in FIG. It is configured to switch between the opened state (hereinafter also referred to as the long mode) and the double-folded state (hereinafter also referred to as the short mode) in which the tool bar 1 illustrated in FIG. 2 is folded and stored in the grip 1. In addition, when not used, it is excellent in portability by taking the two-folded state of FIG. 2, and does not take a storage place.

  Here, the actuator 3 is formed by projecting two finger-hanging portions 3 a and 3 b whose finger-hanging positions move back and forth along the tool bar 1 from the side edges in the longitudinal direction of the tool bar 1 in opposite directions. In the state shown in FIG. 1 (long mode), a finger is placed on the finger rest portion 3a near the grip to perform a sliding operation, that is, the alligator mouth 2 is opened, while in the state shown in FIG. A slide operation is performed by placing a finger on the finger rest portion 3b. Therefore, the actuator 3 can be easily operated while holding the grip 4 in any of the long and short modes.

  Also, in this embodiment, when the grip 4 is folded, almost all of the long mode finger hooks 3a are accommodated in the grip 4 as shown in FIG. There is no fear of erroneous operation of the finger rest 3a, and there is no trouble in appearance, and an aesthetic design is created.

  FIG. 3 is an exploded perspective view of the fish grabber and clarifies the detailed structure of each part. That is, the tool bar 1 is formed by bolting two base plates 1a and 1b having the same shape with a T-shaped spacer 6 and a hollow spacer shaft 7 at a predetermined interval. And between plate 1a * 1b is used as the accommodating part of the said link mechanism.

  Here, the alligator 2 is fixed by fastening one claw 2a to the base plate 1b as described above, while the other claw 2b is rotated by the spacer pipe 9 installed between the base plates 1a and 1b. It is made a movable claw by supporting it as possible.

  On the other hand, the actuator 3 is provided with a slide pin 3c on the alligator side, and is slidable linearly by engaging it with a slide groove 1c provided in the inner surface of the base plates 1a and 1b. The actuator 3 has an alligator mouth by inserting a spring spring (not shown) between the finger hooking portion 3b near the alligator and the convex portion 6a of the T-shaped spacer 6 between the springs 3b and 6a. Is biased to the side.

  On the other hand, the link bar 8 is inserted into the movable claw 2b and the bifurcated crack grooves 2c and 3d of the actuator 3, and the rear end of the link bar 8 rotates the shaft 10 inserted through the slide long hole 3e of the actuator 3. As a moving shaft, it is rotatably supported between the base plates 1a and 1b. At the same time, a rotation pin 8a is provided at the front end of the link bar 8, and this is rotated with the shaft 10 as a fulcrum by engaging with a rotation groove 1d formed in the inner surface of the base plates 1a and 1b. It is.

  The slide pin 3c of the actuator 3 is slidably inserted into and engaged with the inclined long hole 8b formed in the link bar 6, so that the slide motion of the actuator 3 is converted into the rotational motion of the link bar 6. is doing. Furthermore, the movable claw 2b can be opened / closed by the above-described rotation movement of the link bar 6 by slidingly engaging the rotation pin 8a of the link bar 6 with the circular arc hole 2d formed in the movable claw 2b. is doing.

  Next, the structure of the grip 4 and the lock structure will be described. As is apparent from FIG. 3, the grip 4 is configured such that the two grip plates 4a and 4b are opposed to each other via the spacers 12 and 13 and bolted. The rear end of the tool bar 1 is sandwiched between one end of both the plates 4a and 4b, and the tool bar 1 and one end of the tool bar 1 are pivotably connected to each other with the hollow shaft 14 inserted through the spacer shaft 7 as a rotation axis. Is. One grip plate 4a is provided with a knob 5a projecting from a part of the surface so that it can be turned by a bush 15. Further, the knob 5a includes a lock pin 16 protruding through an arcuate guide hole 4c formed in one grip plate 4a. Further, notches 1e and 1f with which the lock pin 16 can be engaged when the tool bar 1 is opened and closed are formed at the rear end edges of the base plates 1a and 1b, and the knob 5a is connected to the lock pin by a spring (not shown). A knob type lock mechanism 5 is configured by urging 16 in a direction to engage with the notches 1e and 1f.

  FIG. 4 shows the opening and closing operation of the alligator 2 by the above-mentioned link mechanism. Normally, as shown in FIG. 4A, the actuator 3 is biased toward the alligator side by the elastic spring S. The movable claw 2b is also elastically maintained in the closed state via the slide pin 3c and the rotation pin 8a. On the other hand, if the actuator 3 is pulled against the elastic force of the elastic spring S and is slid a predetermined distance, the slide pin 3c also follows the slide groove 1c of the base plates 1a and 1b as shown in FIG. Move to the grip side in a straight line. At this time, the slide pin 3c also slides along the inclined long hole 8b of the link bar 8. However, since the inclined long hole 8b is inclined at a predetermined angle with respect to the slide groove 1c, the link bar has an angle corresponding to the inclined angle. 8 rotates. Then, the rotation pin 8a that rotates together with the link bar 8 drives the circular arc hole 2d of the movable claw 2b to open the movable claw 2b. Accordingly, the alligator mouth 2 can be opened while the actuator 3 is being pulled. In this state, if one fingernail is inserted into the fish mouth and then the finger is released from the actuator 3, the spring S It automatically becomes the original closed state, and you can grab the fish mouth with the alligator mouth 2.

  In FIG. 4, the opening / closing operation of the alligator 2 with the toolbar 1 opened is shown. However, since the finger hanging portions 3a and 3b of the actuator 3 slide together in an integrated manner, any finger hanging portion 3a Even if 3b is operated, the operation of the link mechanism is the same. Therefore, it goes without saying that the same opening / closing operation can be performed by pulling the finger hooking portion 3a even when the toolbar 1 is folded in two.

  FIG. 5 shows the folding operation of the grip 4. In the normal state, the lock pin 16 is engaged with one of the notches 1e formed in the base plates 1a and 1b to maintain the long mode state (FIG. 5 ( a)). Here, in this embodiment, when the grip 4 is opened to the maximum, the lock pin 16 is engaged with the notch 1e at an angle of 150 degrees between the tool bar 1 and the grip 4. Therefore, the positional relationship between the grip 4 and the finger rest portion 3a is as if the handle and trigger of the pistol, and the operation of the actuator 3 is easy. In addition, since the tool bar 1 is inclined downward with respect to the grip 4, the work of pinching the fish mouth can be performed in an easy posture. If the knob 5a is rotated against the spring from this state, the engagement is released and the grip 4 can be rotated (see FIG. 5B). By engaging with the other notch 1f, the short mode in the folded state can be maintained (see FIG. 5C). The knob 5a only needs to be rotated only when the lock pin 16 is disengaged, that is, when the lock is released. After that, even if the finger is released from the knob 5a, the grip 4 is rotated by a predetermined amount by the elastic force of the spring. The lock pin 16 naturally engages with the notches 1e and 1f to be locked. Of course, this folding operation can be performed reversibly, and can be performed in the same manner when switching from the short mode to the long mode.

  As described above, the fish gripper of the present invention is characterized in that the tool bar 1 and the grip 4 are pivotally supported so that they can be folded in half, and the long mode is selected according to the fishing content such as the type and size of the target fish. And short mode can be switched to two stages.

  FIG. 6 shows the second embodiment, and the changes from the first embodiment are the following two points. That is, the first change point is that the sharply tapered spatula portion 2a 'is omitted from the fixed claw 2a of the alligator 2 and the hook shape is exactly the same as that of the movable claw 2b. The second change is that the knob type lock mechanism 5 of the grip 4 is provided on the grip plate 4b on the opposite side to the first embodiment. Therefore, in the first embodiment, the grip 4 is held with the right hand and the knob 5a is operated with the left hand, whereas in the second embodiment, the grip 4 is held with the left hand and the knob 5a is operated with the right hand. Can be used for left-handed use.

  FIG. 7 shows a third embodiment, in which the link mechanism for opening the alligator mouth 2 is changed from the first and second embodiments. That is, in this third embodiment, instead of the slide type actuators of the first and second embodiments, a seesaw type actuator 21 that rotates about one of the bolts that bolt the base plates 1a and 1b as the pivot 20 is provided. Adopted. The actuator 21 has a rotation pin 22 that slides in an arc-shaped rotation groove 23 formed in the base plates 1a and 1b with the pivot 20 as a fulcrum, and rotates counterclockwise in the drawing. The actuator 21 is urged clockwise by an elastic body such as a spring or a spring (not shown). On the other hand, one claw 30 of the alligator 2 is supported as a movable claw so that the other one of the bolts can be pivoted about a pivot 31, and a follower pin 32 provided at one end is formed in an arc shape formed on the base plates 1a and 1b. The driven groove 33 is slidably engaged. The actuator 21 and the movable claw 30 are connected by a link bar 41 that is pivotally supported with one of the other bolts as a pivot 40. That is, the link bar 41 has linear elongated holes 42 and 43 through which the rotating pin 22 and the driven pin 32 are inserted and engaged at both ends. 30 is transmitted as a rotary motion, and the movable claw 30 is opened by pressing the actuator 21 with the fingertip against the elastic force of the elastic body. Further, when the finger is released from the actuator 21, the movable claw 30 is rotated in the closing direction via the link bar 41 by the elastic force of the elastic body, so that the alligator 2 is normally closed.

  As described above, also in the third embodiment, the actuator 21 projects the two finger-hanging portions 21 a and 21 b whose finger-holding positions are different in the front-rear direction along the tool bar 1 from the both sides of the tool bar 1 in the opposite direction. The actuator 21 can be easily operated in an open state or a folded state.
