Summary of the Invention
Problem to be Solved by the Invention
[0004] An object of the present invention is to provide a fish skinning tool which enables skinning with light force when skinning fish, allows easy skinning without the skin breaking during operation, and has a simple structure that makes the tool easy to clean.
Means for Solving the Problem
[0005] To solve the above-mentioned problems, that is, to provide a fish skinning tool that allows for easy skinning with minimal force, prevents the skin from tearing during the process, and has a simple structure that makes it easy to clean, the present invention provides a fish skinning tool that has curved slits in a single plate-like surface, with one end of the slit open to the outside of the plate-like surface, and the other end of the slit cut while leaving the edge of the plate-like surface intact. In terms of the cross-sectional shape of the slit, the corners formed by the four slits (two on the front and two on the back) created by vertically cutting the plate-like surface are chamfered on one or both sides of the plate-like surface, and the thickness of the plate-like surface forming the slit is reduced, so that the opposing ends of the slit are sharpened, and the curved slit has cutting edges on the convex and concave sides. [Effects of the Invention]
[0006] According to the present invention, it is possible to provide a fish skinning tool that allows for skinning with minimal force, prevents the skin from tearing during the process, and has a simple structure that makes the tool easy to clean. [Brief explanation of the drawing]
[0007] [Figure 1] This is a perspective view of the first embodiment of the present invention, in which only one side of a plate-shaped plate has its corners chamfered and sharpened by making vertical slits. [Figure 2] This is a cross-sectional view illustrating the shape of the slit in the first embodiment of the present invention. [Figure 3] This is a perspective view of a second embodiment of the present invention, in which a plate-shaped plate is sharpened by chamfering the corners by making vertical slits on both sides. [Figure 4] This is a cross-sectional view illustrating the shape of the slit in a second embodiment of the present invention. [Figure 5] This is a cross-sectional view illustrating the mechanism and usage of the debarking device of the present invention using a second embodiment of the present invention. [Figure 6]This is a perspective view illustrating the mechanism and usage of the debarking method of the present invention using a second embodiment of the present invention. [Modes for carrying out the invention]
[0008] The embodiments of the present invention will be described below with reference to the drawings. A first embodiment of the present invention will be described with reference to Figures 1 and 2. In Figure 1, the fish skinning tool 1 has a curved slit 3 in a resin plate 2, one end of the slit 3 is open to the outside of the plate 2, and the other end of the slit 3 is cut, leaving the end of the plate 2 intact. Figure 2 illustrates the cross-sectional shape of the slit 3. Of the four vertical slits 4 formed by vertically slitting the plate-shaped plate 2 (two on the front and two on the back), the two vertical slits on one side of the plate-shaped plate 2 are chamfered, and the thickness of the plate-shaped plate 2 forming the slit 3 is reduced. As a result, the opposing ends of the slit are sharpened, and the curved slit has a convex cutting edge 6a and a concave cutting edge 6b. The corner 4 on the convex side of the curved slit, formed by the vertical slit, is chamfered at a convex chamfering angle αa. By removing thickness from the plate-like plate 2, the cutting edge 6a on the convex side of the curved slit is formed at the cutting angle created between the convex chamfered portion 5a and the unchamfered surface of the plate-like plate 2. The corner 4 on the concave side of the curved slit, created by the vertical slit, is chamfered at a concave chamfering angle αb. As the thickness of the plate-like plate 2 is reduced, the concave cutting edge 6b of the curved slit is formed at the cutting angle created between the concave chamfered portion 5b and the unchamfered surface of the plate-like plate 2. This design solves the problems associated with skinning fish by allowing skin to be removed with minimal effort, preventing the skin from tearing during the process, and making the tool easy to clean thanks to its simple structure. A second embodiment of the present invention will be explained in Figures 3 and 4. In Figure 3, the fish skinning tool 1 has a curved slit 3 in a resin plate 2, one end of the slit 3 is open to the outside of the plate 2, and the other end of the slit 3 is cut away, leaving the end of the plate 2 intact. Figure 4 illustrates the cross-sectional shape of the slit 3. By making vertical slits in the plate-shaped plate 2, a total of four vertical slits are formed, two on the front and two on the back. The four vertical slits on both sides of the plate-shaped plate 2 are chamfered, and the thickness of the plate-shaped plate 2 forming the slit 3 is reduced. As a result, the opposing ends of the slit are sharpened, and the curved slit has a convex cutting edge 6a and a concave cutting edge 6b. The corner 4 formed by the vertical slit on the convex side of the curved slit is chamfered from both sides of the plate-shaped plate at a convex chamfering angle αa, and by removing the thickness of the plate-shaped plate 2 from both sides, the cutting edge 6a on the convex side of the curved slit is formed at the cutting angle formed from the front and back surfaces of the convex chamfered portion 5a of the plate-shaped plate. The corner 4 on the concave side of the curved slit, formed by the vertical slit, is chamfered from both sides of the plate-like plate at a concave chamfering angle αb. By removing thickness from both sides of the plate-like plate 2, the blade angle formed from the front and back surfaces of the concave chamfered portion 5b of the plate-like plate creates the convex cutting edge 6b of the curved slit. In this embodiment, unlike the first embodiment of the present invention, the front and back of the plate-shaped plate are symmetrical, so that it can be used by both right-handed and left-handed users. Similar to the first embodiment of the present invention, the problems of skinning fish are solved by enabling skinning with light force, allowing for easy skinning without the skin tearing during the process, and by making the tool easy to clean due to its simple structure. The mechanism and usage of the debarking method of the present invention will be explained using a second embodiment of the present invention in Figures 5 and 6. Fig. 5 is a cross-sectional view for description. First, the tail end of the fish carcass (with skin) A is clamped by the fish bone gripper B, and the fish carcass (with skin) A is placed on the plate-shaped plate 2 while the tail end is clamped into the slit 3 of the fish skinning device 1. Next, the tail end is pulled out from the slit in a direction perpendicular to the plate-shaped plate 2 using the fish bone gripper B, whereby the fish meat Ab remains on the upper side of the plate-shaped plate, and only the fish skin Aa comes out of the slit. Fig. 5 shows an intermediate state during the process of pulling out the aforementioned fish skin Aa. For such a fish carcass (with skin) A, the angle formed by the traveling direction of the fish meat Ab to be skinned and the traveling direction of the fish skin Aa to be separated is the separation angle β between the meat and the skin. Since the skin is separated when the separation angle β between the meat and the skin is an obtuse angle, the skin can be easily separated even with a light force. Fig. 6 is a perspective view illustrating the state of Fig. 5. As mentioned above, the slit 3 is cut in a curved shape, and has a curved convex cutting edge 6a and a concave cutting edge 6b. Therefore, in the process of skinning, tensile force is applied to the central portion Ca of the skin first, after the central portion Ca of the skin is separated first, the two end portions Cb of the skin are separated sequentially. As a result, the fish skin is less likely to be torn during the skinning operation, so that failures are less likely to occur. The fish bone gripper B is omitted in Fig. 6. [Industrial Applicability]
[0009] The present invention can be utilized as a fish skinning device. [Description of Reference Signs]

Claims
[Claim 1] This fish skinning tool has a curved slit in a single plate-like surface, with one end of the slit open to the outside of the plate-like surface, and the other end of the slit cut open while leaving the edge of the plate-like surface intact. The cross-sectional shape of the slit is characterized by the fact that, in addition to the four corners formed by the slits on both sides of the plate-like surface (two on the front and two on the back) formed by vertically cutting the plate-like surface, the corners formed by the slits on one side or both sides of the plate-like surface are chamfered, and the thickness of the plate-like surface forming the slit is reduced, so that the opposing ends of the slit are sharpened, and the curved slit has cutting edges on the convex and concave sides.
