This invention provides a fish holding tool for safe and secure holding of a caught fish for purposes such as removing a hook from its mouth.
Landing or removing a caught fish from the water, removing the hook from its mouth, and placing it on a stringer or in a container are difficult aspects of fishing because of the struggling of the fish and the sometimes awkward, unbalanced, extending positions or stances required to be taken by the fisher reaching towards the water, possibly from a rocking boat. If it is desired not to injure the fish, such as with catch-and-release fishing, it becomes even more difficult. Tools are known which are intended to make these tasks easier and safer, but such known tools tend to underperform, sometimes by being too rigid and solid, therefore injuring the fish and tending to sink when dropped in the water, sometimes by being too lightweight, therefore tending to twist and deform and failing to maintain a grip in use, and oftentimes by being difficult to take in hand when needed, and difficult to keep a grip on and use in real fishing conditions.
What is needed is a fish holding tool that can achieve the stability of rigid, dense materials but using lighter, buoyant materials, and which is easy, safe, and secure to take in hand and use under real fishing conditions.
This invention provides a fish holding tool for safe and secure holding of a caught fish for purposes such as removing a hook from its mouth. The fish holding tool operates as a pliers having a planar four-bar toggle linkage, where the upper jaw of the upper member remains stationary and the lower jaw is opened and closed by manipulation of the lower handle. The fish holding tool is made of a lightweight, buoyant material, having potential to be deformable and unstable when closed upon the lower mouth of a struggling fish, especially if too much gripping force is applied, making it likely that the fish will be harmed and the gripping tool will distort. The fish holding tool avoids the potential stability problem by the positioning of a lower-jaw tab into an upper-jaw slot, and by a toggle linkage having a toggle-linkage bumper, which also operates to prevent excessive pressure applied to the lower handle from distorting the tool or damaging the fish.
The fish holding tool provides a tapered extending tip on the forward end of the upper jaw, which facilitates the opening of the mouth of the caught fish even against a “lockjaw” condition where the fish forcefully holds its mouth closed in reaction to having been hooked.
In order to facilitate easy and secure gripping in wet conditions with a struggling fish, the fish holding tool provides a molded grip texture on the outer surfaces of both the upper handle and the lower handle and provides an upper-handle bulbous end and a lower-handle bulbous end. The fish holding tool also provides a lanyard with a buoyant lanyard-end terminator which facilitates easy retrieval, a secure grip during use, and buoyancy of the entire tool if dropped into the water.
Reference will now be made to the drawings, wherein like parts are designated by like numerals, and wherein:

The fish holding tool 10 provides a tapered extending tip 13 on the forward end of the upper jaw 11, which facilitates the opening of the mouth of the caught fish even against a “lockjaw” condition where the fish forcefully holds its mouth closed in reaction to having been hooked.
In order to facilitate easy and secure gripping in wet conditions with a struggling fish, the fish holding tool 10 provides a molded grip texture 8 on the outer surfaces of both the upper handle 14 and the lower handle 3, and provides an upper-handle bulbous end 15 and a lower-handle bulbous end 35. The fish holding tool 10 also provides a lanyard 6 with a buoyant lanyard-end terminator 65 which facilitates easy retrieval, a secure grip during use, and buoyancy of the entire tool if dropped into the water.
The fish holding tool 10, when in use, has nominally upper and lower, or vertical, front and back, or axial, left and right, or lateral, orientation, as shown.
Referring additionally to
A molded grip texture 8 is molded into the upper handle 14 and lower handle 3 during manufacture. An upper-handle bulbous end 15 and a lower-handle bulbous end 35 are provided. A lanyard 6 with a buoyant lanyard-end terminator 65 is also provided. Together, these facilitate both the initial taking up in hand of the fish holding tool 10, and the secure use and operation of the fish holding tool 10 on a struggling hooked caught fish. The buoyancy of the entire fish holding tool 10, plus the added buoyancy of the buoyant lanyard-end terminator 65, ensure that in the likely event that the fish holding tool 10 is dropped in the water, it will be retrievable. The size and substantially ball-like shape of the buoyant lanyard-end terminator 65 provides a good way to take up the fish holding tool 10 from a tackle box or the bottom of a boat, or to fish it out of the water.

At the back of the upper-member slot 12 the lanyard 6 is secured to the upper handle 14 with a non-corroding lanyard pin 7 through a suitable hole, as shown. The considerations for the non-corroding lanyard pin 7 are substantially the same as for the non-corroding pivot pins 5, above.
The lower jaw 2 is provided with a lower-jaw strut 21, which is a lateral thickening of the lower jaw along the portion extending forward to terminate the jaw, as shown, for strength and stability of the lower jaw without increasing the weight and bulk of the lower jaw.
The lower jaw 2 is provided with a lower-jaw tab 22 on the middle upper portion of the lower jaw. The lower-jaw tab 22 has a lateral width corresponding to the width of the upper-member slot 12, such that the lower-jaw tab 22 fits snugly into the upper-member slot 12, but is able move into and out of the slot, in use. The edges of the lower-jaw tab 22 are rounded, beveled, or tapered such that the lower-jaw tab 22 is guided into the upper-member slot 12. When the lower-jaw tab 22 is seated in the upper-member slot 12, the fish holding tool 10 is strengthened and stabilized against twisting and distortion. The lower-jaw tab 22 is shaped such that a portion of the tab will enter into the upper-member slot 12 early during the process of closing the jaw, in order to provide strength and stabilization early in the process of gripping the caught fish.
The lower jaw 2 is provided with two pivot-pin holes, one above and one below, near the back of the lower jaw 2, to accommodate non-corroding pivot pins 5 as treated below. The lower jaw 2 is provided with a lower-jaw double-stop 23 to stop against either the upper member 1 or the lower handle 3 and prevent over-opening or over-closing of the jaw, as treated below.
The lower handle 3 is of a curved shape overall, with an undulating lower surface providing finger grips, and provides a lower-handle bulbous end 35 and a molded grip texture 8 to the facilitate the user taking up and manipulating the fish holding tool 10. The lower handle 3 provides a lower-handle slot 31 in the forward and the forward-upper portion of the handle, as shown. In a preferred embodiment, as shown, the lower-handle slot 31 is of the same lateral width as the upper-member slot 12, allowing the structures intended to fit into those slots to be of a uniform width, as well. Optionally, the lower-handle slot 31 can be extended rearward in order to lower the amount of material in the handle. A lower-handle brace 32 is provided on the middle, upper surface of the lower handle 3. The lower-handle brace 32 extends laterally across the upper surface of the lower handle 3, and both strengthens and stabilizes the lower handle 3, and provides a surface for the toggle-linkage bumper 41 to stop against, as treated below.
Two pivot-pin holes, one forward and one rearward, are provided both near the front of the lower handle 3, running laterally through the lower handle and the lower-handle slot 31, to accommodate two non-corroding pivot pins 5, as shown, and as treated below.
The toggle linkage 4 is of a lateral width corresponding to the widths of the upper-member slot 12 and the lower-handle slot 31, and is meant to pivot within both slots. The toggle linkage 4 is elongated with pivot-pin holes at opposite ends. The toggle linkage 4 is provided with a toggle-linkage bumper 41 that strengthens the toggle linkage 4, stops any further movement of the lower handle 3 towards the upper handle 14, and, when squeezed between the upper handle 14 and the lower-handle brace 32 on the lower handle 3, further stabilizes and supports the handles against twisting and distortion.
In assembly of the fish holding tool 10, the upper back portion of the lower jaw 2 is placed into the upper-member slot 12 such that the upper pivot-pin hole of the lower jaw 2 is in line with the forward pivot-pin hole of the upper member 1, and is secured in place by a non-corroding pivot pin 5, forming a pivot, or revolute, joint with one degree of freedom. The lower back portion of the lower jaw 2 is placed into the lower-handle slot 31 such that the lower pivot-pin hole of the lower jaw 2 is in line with the backward pivot-pin hole of the upper member 1, and is secured in place by a non-corroding pivot pin 5, forming another pivot joint.
In assembly, the upper backward portion of the toggle linkage 4 is placed into the upper-member slot 12 such that the upper, backward pivot-pin hole is in line with the backward pivot-pin hole of the upper member 1, and is secured in place by a non-corroding pivot pin 5, forming another pivot joint. The lower forward portion of the toggle linkage 4 is placed into the lower-handle slot 31 of the lower handle 3 such that the lower, forward pivot-pin hole is in line with the forward pivot-pin hole of the lower handle 3, and is secured in place by a non-corroding pivot pin 5, forming another pivot joint.
In use, movement of the lower handle 3 upward and toward the upper handle 14 will move the lower jaw 2 toward the upper jaw 11, closing the fish holding tool 10. The lower-jaw double stop 23 will stop against the lower handle 3, will provide some resistance to further, excessive movement of the lower handle 3, and will apply a counteracting opening force to the lower jaw 2. Movement of the lower handle 3 downward and away from the upper handle 14 will move the lower jaw 2 away from the upper jaw 11, opening the fish holding tool 10. The lower-jaw double stop 23 will stop against the upper member 1 and limit the amount or degree of opening.
In use, the fish holding tool 10 functions as a planar four-bar toggle linkage, with four pivot or revolute joints each having one degree of freedom. The structure and the materials used in the fish holding tool 10 allow just enough deformation of the toggle linkage 4 to reach just beyond the toggle position, where the linkage folds and the fish holding tool 10 becomes locked into position, clamping upon the lower mouth of the caught fish with sufficient, but not excessive, force. Any application of additional force to the handles, as would be likely to happen during the handling of a struggling caught fish, is stopped and prevented from increasing the clamping force or deforming the tool by the toggle-linkage bumper 41 preventing any further movement of the lower-handle brace 32 toward the upper handle 14.
