Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scissor device which is extremely effective for capturing and taking out desired live fish from, for example, an aquarium.

[0002]

2. Description of the Related Art Heretofore, as a device for grasping a living fish, megochi scissors have been proposed for fishing. As shown in FIGS. 6 (a), 6 (b), 7 (a), and 7 (b), the tongs scissors are formed by pressing a metal plate. It is a grip portion 1 that is formed by bending a belt-shaped member having a predetermined width into a substantially U shape and is kept open by elastic force, a grip portion 2 that extends continuously from the grip portion 1, and scissors thereof. In this configuration, mountain-shaped concave-convex portions 4 facing each other are provided at the edges of the flat portions 3 of the portion 2 which face each other. The one shown in FIG. 6 is different from the one shown in FIG. 7 in that the grip portion 1 and the scissor motion portion 2 are bent and connected. Note that ice scissors (ice tongs) are known in a shape similar to that shown in FIG. The Megochi scissors are used to hold the Megochi in between, and are used to prevent the fish from being directly touched when the fishing hook is removed from the chime for fishing. If you grab the mess directly with your hand,
It is used to prevent slipping because it is slippery, and to prevent it from slipping because it does not easily fall off, and to prevent injury to the hand due to the presence of the spine. In general, tweezers are well known for sandwiching a small object.

[0003]

When a fish is taken out from a cage or the like for cooking at a live fish restaurant, the fish is scooped up with a net and directly grasped by a hand. At this time it is quite difficult to grab a live fish. In addition, it is often difficult to catch a desired fish with a net. Although it is possible to use mego-scissors for such problems, aside from fish that are small and not so violent like megochi, when it comes to larger fish such as sea bream and machi, the mego-scissors become larger. Even if it is formed into a thing, it does not come out easily. The reason is that the unevenness 4 is arranged on a straight line. That is,
When pinching a fish, it is common to pinch the part of the body close to the head of the fish, and its cross section ranges from a flat ellipse to a shape close to a circle, but since such a convex surface is sandwiched by straight lines This is because the scissors 2 having both the irregularities 4 contact the fish tangentially. Also, when sandwiching a slightly larger fish, the grip part 1 of the conventional megochi scissors and the scissors part 2 connected to this
With this configuration, there is a problem that it is difficult to use because it is easily bent in the middle. In addition, tweezers are small and common scissors, but when grasping a part of an object at the time of dissection in a laboratory, grasping fry and observing them, etc. There is a problem that it is difficult to use because it is easy. An object of the present invention is to provide a scissor device having scissors, which can easily catch live fish, and can be made smaller than conventional tweezers when gripping a slippery object by making it small. And

[0004]

The scissors device of the present invention comprises:
A scissors instrument having a pair of scissors provided so that the front side opens and closes, and a handle provided at the base side to manually open and close the scissors, in at least one of the pair of scissors. Is formed into two loops from the handle portion side and extends with a gap therebetween and is continuous with each other at the tips, and edges of both sides of the scissor portion facing each other are formed with anti-slip portions. And The scissors are preferably formed in a plate shape along the opening / closing direction. And
Both of the pair of scissors may be loop-shaped, or only one may be loop-shaped and the other may be rod-shaped. Even when the other is rod-shaped, it is preferable to form the rod-shaped portion in a plate shape along the opening / closing direction. The scissors preferably have a pair of scissors with at least one edge formed with a non-slip portion having a concave edge with respect to the other side. In the case where the scissors have a loop shape, the anti-slip portion is preferably a blade formed of a ridge along the extending direction of the edge portion where the anti-slip portion is formed. Further, when one of the scissors is in the shape of a single rod, it is preferable that the scissors have uneven teeth.

[0005]

According to the above-mentioned means, since at least one side of the pair of scissors is formed in a loop shape, the scissors can be lightly formed of the same material, and the object to be sandwiched is contacted not by a flat surface but by a loop surface, which is small. The contact area allows a wide range of contact, and the contact pressure is appropriately increased, so that stable scissors can be obtained, and the water resistance during opening / closing operation of the scissors in water is small and agile. Scissors can be operated, and further, the bending is less and the strength is stable compared to the case where the tip is separated. When the scissors are formed in a plate shape along the opening / closing direction, the resistance of water is further reduced, and since the scissors are loop-shaped, the thickness of the plate-shaped portion can be reduced. If the edge of the scissors that has a non-slip portion on one side is formed as a concave edge with respect to the other side, the edge will abut along the surface of the fish when sandwiching the fish. , Scissors There is little relative movement between the scissors and the fish, resulting in stable scissors. As for the non-slip part, when the scissors have a blade with a looped shape and convex stripes, it is possible to focus on the slip in the direction perpendicular to the extension direction of the blade, that is, the left-right direction, and the scissors have a rod shape. And those with uneven teeth,
The slip in the longitudinal direction, that is, the front-back direction can be stopped intensively.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIG. The scissors device 1 of this embodiment is a fish scissors device used in a restaurant or the like when catching live fish in a fish cage, for example, snapper, flutter, karei and the like for cooking. Scissors instrument 1
Is a pair of scissors 2 provided such that the front side opens and closes.
And a handle portion 3 provided to open and close the scissors portion 2 with one hand. As shown in FIG. 1B, the pair of scissors 2 has one part 2a which is divided into two parts from the handle part 3 side, which extend at a gap 4 and are continuous with each other at the tips. This is a shape in which a generally elongated metal plate-shaped material is bent so as to be bent in the middle, and both ends are connected to the handle portion 3 with a space therebetween. The other portion 2b has a shape obtained by extending a single elongated plate from the handle 3. The plate surfaces of the portions 2a and 2b of the scissors portion 2 are arranged so as to follow the opening / closing direction, that is, open / close in the plane shape shown in FIG. 1 (b) at right angles to the paper surface. Appears in a predetermined narrow width. Further, as shown in FIG. 1A, the portions 2a and 2b of the scissors portion 2 have a side surface shape that is gradually narrowed from the handle portion 3 side toward the front, and the edges facing each other vertically It is formed in a concave shape, and anti-slip portions 5 and 6 are formed on the edge of the concave shape. The non-slip portion 5 is formed as a blade whose outer surface on the edge is an inclined surface. The non-slip portion 6 is a tooth having a saw tooth shape. The non-slip parts 5 and 6 are convex blades or serrated teeth, but the tips of the blades or teeth are not sharp enough to cut through the skin of fish. That is, as shown in FIG. 1 (c), the blade of the portion 2a is formed by providing the bevel of the edge with a gentle downward slope to the outside, and the tooth of the portion 2b appears with a horizontal line at the tip. However, it is not like a saw or a knife.

The handle portion 3 is composed of two annular portions 7 and 8 that can be operated with one hand, and one of the annular portions 7 is a forked portion 7.
a, the forked portion 7a is connected to the scissors 2a, and the other annular portion 8 has a connecting portion 8a.
The scissors 2b are continuous with a. A connecting portion 8a is positioned between the fork-shaped portions 7a, and a main shaft 9 is provided so as to penetrate both of them. When the thumb and four fingers of the other hand are inserted into the annular portions 7 and 8 of the handle portion 3 to open and close between the annular portions 7 and 8, the shaft 9 rotates about the pivot shaft 9 and 2a of the scissors portion 2a. 2b opens and closes.

The scissors device 1 can carry a fish picked up from the cage by a net or a fish in the cage and lift it as it is to carry it to a desired position. When the fish is sandwiched, the scissors 2a that is in contact with the fish on one side has two curved edges, and the scissors 2b that is in contact with the fish on the other side has one curved edge. The non-slip part 5 mainly stops the left and right slips, and the non-slip part 6 mainly stops the forward and backward movements, and in addition to this, the fish moves forward and backward of the scissors instrument 1. Hard to do. In particular, it is curved so that it will not move to the front side and come off. Further, since the opposite side of the position where two points are in contact on one side is contacted at one point of the intermediate position, there is a pressing force that bends the fish by the contact of three points. It is difficult to move to the left and right of 1. Therefore, the fish grasped by the scissors instrument 1 is firmly grasped and does not easily fall off. When grasping a fish in a cage, the scissors 2 are opened and closed in water. When opening and closing the scissors 2, the scissors 2 are plate-shaped and extend in the opening / closing direction. It can be closed easily and the movement of water that drives away fish is unlikely to occur, making it easy to catch live fish.

A second embodiment is shown in FIG. The scissors 11 of this embodiment is a relatively small live fish, for example
It is designed to grab an egg and shrimp. The difference from the first embodiment is that the handle portion 13 uses the elasticity of metal without using a shaft, and the slip preventing portions 15 and 16 are different.
Is formed on the small chevron teeth and the scissors 12
Is formed to be small. Scissors section 12
Has a shape similar to that of the first embodiment and is formed to be slightly smaller. The handle portion 13 is formed by bending a metal thin plate material in the middle portion to form a grip-type chopstick shape, one end 17 of which has one portion 12 a of the scissors portion 12 and the other end 18 of which has the scissor portion 12. The other portion 12b of each of these is attached by welding. In this welding, the handle portions 17 and 18 face each other with a plate-shaped surface, but the scissors portion 12 faces each other with a plate-shaped edge portion. Therefore, the handle portion and the scissor portion have a plate-shaped surface at a right angle. It is welded so that. In the figure, 14 is a gap.

In the scissors 11 of this embodiment, the handle portion 13 maintains the scissor portion 12 in an open state in a natural state, and by grasping the whole one so that one 17 of the handle portions 13 approaches the other 18. Since the scissors portion 12 is closed, the fish can be pinched and grasped at this time. This gripped state is substantially the same as in the first embodiment. Therefore, the action and effect are similar.

FIG. 3 shows a third embodiment. This example is
The present invention is applied to the tweezers 21 and is smaller than that of the second embodiment. Main points different from the second embodiment are that the whole is formed small and the scissors portion 2
2 is a point where both are formed into a loop, and the edges where the blades are formed as the anti-slip portions 25 and 26 are straight without bending. The handle 23 is, in principle, the same as that of the second embodiment, utilizing the elasticity of metal, and is composed of portions 27 and 28. In the figure, 24 is a gap, 2
9 is a long hole. The long holes 29 weaken the elasticity of the handle portion 23, and when a predetermined object is sandwiched, the portion 27 of the handle portion 23,
It is designed so that the force for pinching the object does not become larger than a certain amount when 28 is completely closed.

The tweezers 21 are for sandwiching slippery objects, and are used, for example, for operation for screening disease of juveniles for aquaculture and selection. This scissors part 22
The plate-shaped surfaces of a and 22b are parallel to the opening / closing direction. Therefore, even when the portions 27 and 28 of the handle portion 23 are used in such a manner as to bend, the scissors portions 22a and 22b do not bend because they receive an acting force not in the thickness direction of the plate but in the width direction.

The tweezers as in the third embodiment may separately have the tweezers 41 as the fourth embodiment, and partially have twisted portions 32a and 32b as shown in FIG. 4 (a). The processing is performed by forming a punched shape shown in FIG. 4B into a continuous portion 3 of the handle 33 and the scissors 32.
The twisting and bending of 90 ° may be applied within a predetermined range W near 9 and the tip may be bent about 180 ° along the broken line 33.

As a modification of the first embodiment, FIG.
As shown in (a), when the fish is slippery and long and slender such as eel and conger, the side surfaces of the opposite edges of the portions 52a and 52b of the scissors 52 are formed into a shape close to a circle,
Uneven teeth are also formed on the edges of the portion 52a. The scissors device 51 is not only used for taking out fish from live fish cages in live fish restaurants, etc., but is also very convenient for removing fishing hooks from caught eels, conger eels, crucibles, mackerels, etc. 5
3 is a handle. FIG. 5B shows a shape that can be applied in place of the portion 2a of the scissor portion 2 of the first embodiment or the portion 12a of the scissor portion 12 of the second embodiment, and straddles both sides of the portion 62a of the scissor portion 62. It is configured such that several reinforcing members 60 in the lateral direction are provided. This number is set to one or more as needed. The reinforcing member 60 is formed on a non-slip portion 64 consisting of a continuous edge of a not so sharp edge, and the edge is provided with a non-slip portion 65 of a part 62a of the scissor portion 62 where a not so sharp blade (edge) is continuous. The edges are continuous at the same height. The anti-slip portions 64 and 65 may be formed on the above-mentioned tooth of unevenness, or may be configured to have both the blade and the unevenness.

In the first embodiment described above, the grip structure has been shown in which the handle portion, which is not too long, can be operated with one hand. However, in some cases, it may be convenient to use a longer handle portion.
For example, in a large cage, fish (octopus,
When it is desired to capture squid, shrimp and the like), a long handle is preferable, and in such a case, a conventional drive mechanism of high branch scissors may be employed to lengthen the handle.

In the above-mentioned first and second embodiments, it was explained that the object to be sandwiched is a live fish, but since it can be grasped without touching it directly with the hands, even a dead fish does not have another step and supports. As a method of using the scale, it is possible to operate the scissor device with one hand to hold the fish and use the scale device with the other hand when performing scale removal. It may also be used when operating something that is difficult to operate directly with hands other than fish. In addition, although the side surface shape of both of the facing edges where the anti-slip portion of the scissors is formed is curved, but in some cases, one side is curved to be concave and the other side is curved. It may be formed on a straight or convex edge. The point is that it is enough to properly sandwich and hold the sandwiched object. Depending on what is grasped, one or both sides of the scissors formed in the loop may have a plurality of loop shapes of two or more.

In the third embodiment described above, the scribing portion of which the anti-slip portion is formed has a straight edge, but it may be concave or convex if necessary. Good.

In each of the above embodiments, the material of the scissors is metal, but the material is not limited to this, and synthetic resin, composite material or the like may be used, and synthetic resin, ceramics or wood may be partially used for the non-slip portion. Etc. may be used. The anti-slip part of the scissors is appropriately selected in consideration of the easiness of damaging the object to be sandwiched. Further, although the non-slip portion of the non-slip portion applied to the fish scissors device has a sawtooth shape or a mountain shape in the embodiment, the cross-sectional shape may be flat on the front side or angled edge shape. Well, the point is that it should be held so that the skin of the fish does not break.

[0019]

According to the scissor device of the first aspect of the present invention, at least one of the pair of scissors has a loop shape, and the edges of both sides of the scissors facing each other are formed with the non-slip portions, so that a small contact is made. Since it is possible to make contact with a wide area over a wide area and the contact pressure is appropriately increased, stable scissors can be obtained, and the resistance of water when opening and closing the scissors in water is small, and the agile scissors can be used. It becomes possible to operate, and moreover, the looped shape has less bending and becomes stable in strength than the case where the tip is separated, so that it becomes easy to grasp and support a live fish. Therefore, it is applied to scissors for taking out fish from the fish cage for cooking at a live fish restaurant or the like, and the fish can be easily handled. Further, it is also useful for holding fish for removing fishing hooks in fishing, and particularly for holding slippery fish or fish with spines. Further, when applied to tweezers, it has an effect of making it easy to grasp when it is slippery when grasping fry, dissection, surgery and the like. The scissors according to claim 2 is, in addition to the scissors according to claim 1, one of the scissors is rod-shaped and is combined with the loop-shaped part, so that the scissors are supported at three points, and the scissor force is sandwiched at three points. It effectively acts like bending and can be strongly held, and the structure is simple, and the operation in water is even easier. In addition to the scissors according to claim 1 and claim 2, the scissors according to claim 3 have scissors formed in a plate shape along the opening / closing direction, so that the resistance of water during opening / closing operation in water is Since it is further smaller and has a loop shape, it is advantageous in terms of strength and the thickness of the plate-shaped portion can be reduced. Therefore, when you grab a fish in a cage etc. directly with scissors,
The movement of water that a fish perceives is unlikely to occur, making it easy to grab a fish.

A scissors instrument according to a fourth aspect is the first aspect.
In addition to what is claimed in claim 2 or claim 3, the scissors are formed such that an edge formed with a non-slip portion on at least one side of the pair of scissors is a concave edge with respect to the other side. Therefore, when the fish is grabbed, the concave edge abuts the fish in a wider area along the outer shape of the fish, so there is less relative movement between the scissors and the fish, and a more stable scissors state is possible. Play. In addition to the scissors according to claims 1 to 4, the scissors according to claim 5 has uneven teeth on the rod-shaped part of one scissors, so that the scissors for sandwiching can prevent the scissors from sliding in the front-rear direction. It is more slippery and easier to grip. In addition to the scissors according to claims 1 to 5, the scissors according to claim 6 is provided with a blade on the loop-shaped scissors, so that the scissors for sandwiching the scissors stop the lateral movement of the scissors, which makes it more slippery. It has the effect of making it easier to grab things.
