Auxiliary tool for oysters {Open-device for oyster-shell}

The present invention relates to an auxiliary tool for digging oysters, and more particularly, to an auxiliary tool for digging oysters that can reduce the labor intensity of workers who dig oysters manually and prevent safety accidents that may occur during work up to oysters .

In general, oysters are a generic name for shellfish belonging to the oyster family of the mollusk tribal family (斧足類), and it is known as a health food containing various nutrients such as vitamins, minerals, and amino acids. .

These oysters are mainly used for tonicity, strength, strengthening of liver function, anemia, cerebral hemorrhage, neurasthenia, thyroid disease, etc. The taurine component in oysters is good for brain development as well as stroke, arteriosclerosis, diabetes, and especially good for skin care is known to represent

In raw oysters, the upper and lower two shells (shells) exist in a very strongly closed state, which is due to the strong muscle of the oyster called adductor muscle that holds the upper and lower shells from the inside.

Because the shell of raw oysters exists in a closed state with very strong force due to the adductor muscle, it is impossible to open the adductor muscle as it is. must be opened

In particular, in order to consume raw oysters, a hard shell must be opened. In most cases, a sharp blade is forcibly inserted into one end of the shell to open the shell by turning the blade at a certain angle, or a separate cutting tool such as a bench After cutting one end using a oyster, a knife was inserted inside through the cut open gap to cut the adductor muscle of the oyster, and then both shells were opened to ingest the contents.

Therefore, this operation is very cumbersome because an auxiliary tool such as a separate bench is required to consume oysters, and also, from the point of view of the general consumer, the adductor muscle existing inside the shell is not visible from the outside. In order to cut, the adductor muscle must be found while the knife is stirred while the knife is inserted. In this case, there is a problem that not only the adductor muscle but also the contents inside the shell are damaged.

In addition, while applying excessive force to insert the auxiliary tool into the tightly closed shell, the sharp tip of the blade deviated or slipped from the inside of the shell, and accidents of stabbing or cutting the user's hand holding the oyster shell were not uncommon.

As described above, in the case of conventional oysters using an auxiliary tool to dig oysters, it takes a lot of effort by the worker, takes a lot of work time, reduces productivity, and causes safety accidents for workers. it was the case.

Of course, in order to solve the problem of manual oyster shelling, some methods of shelling oysters using a mechanical device have been suggested.

However, such a mechanical device has a problem that the structure is complicated and the volume of the device is large, so that small workshops, oyster processors, and general consumers cannot use it.

1 is an external perspective view of an auxiliary tool 100 for cracking oysters according to an embodiment of the present invention.

The auxiliary tool 100 for cracking according to the present invention shown in FIG. 1 includes a pair of upper and lower handle members 20 and 21 on one side based on a pair of rotating members 10 and 11 provided in the central part; It has a structure in which a pair of first and second shell opening members 40 and 41 provided on opposite sides of the handle members 20 and 21 are provided.

In addition, a pair of shell crushing members 60 and 61 are provided on the inner surfaces of the pair of handle members 20 and 21 to face each other and contact each other when the handle members 20 and 21 are pressed.

In addition, the resilient means 50 for elastically rotating when a certain external force is applied between the upper and lower rotation members 10 and 11 is installed on the rear side of the rotation members 10 and 11 .

In more detail one embodiment of the present invention shown in Figure 1, as shown in the drawing, the auxiliary tool 100 for cracking according to the present invention is made of a pliers structure, which is a type of tool, and the central A pair of rotating members 10 and 11 provided on the side are vertically coupled with respect to the fixing part 13 so that the left and right ends can rotate up and down around the fixing part 13 .

In addition, the pair of handle members (20, 21) each connected to one end of the pair of rotation members (10, 11) made of a predetermined length so that the user can hold it by hand, the user grips with one hand. A certain distance is maintained between the upper and lower handle members 20 and 21 to enable up-and-down operation, and the upper and lower gap is an appropriate gap through the resilient means 50 vertically coupled to the rear side of the rotating members 10 and 11. structure that is maintained.

In addition, each of the inner surfaces of the handle members 20 and 21 is in contact with each other when the handle members 20 and 21 are pressed to cut or crush the shells of oysters located therebetween (60,61). ) is provided with a structure.

The shell crushing members 60 and 61 are preferably made of a metal material so that the user can easily cut or crush a portion of the shell of the hard oyster by the pressing force pressing the handle members 20 and 21, and are deformed or damaged due to frequent use. It is more preferable to be configured to have a ∧-shaped cross-section to prevent it from happening.

In addition, the cutting edge portion 63 of the shell crushing members 60 and 61 has a concave-convex or serrated engagement portion 63 to prevent the shell from sliding when the upper and lower shell crushing members are pressed to cut the shell. It is preferable that the structure is formed so that the shell can be cut or crushed with a small pressing force of the handle members 20 and 21 .

On the other hand, on the front side of the rotating members 10 and 11, which are opposite sides of the handle members 20 and 21, the first and second shell opening members 40 and 41 of a relatively thin plate type having a constant width and length and a relatively thin thickness. ) is provided as a pair of upper and lower sides, and is configured to have a structure that can be adjusted to each other according to the rotation operation of the rotation members (10, 11).

That is, the first and second shell opening members 40 and 41 are inserted between the upper and lower shells of the oyster to open the shell or to remove the contents (oysters) attached to the inner surface of the opened shell. That is, it is preferably made of a material having a thin and strong rigidity, and a blade is formed at the tip or side end thereof so that it is easy to remove the temporal portion attached to the inner surface of the shell.

The auxiliary tool 100 for cracking according to an embodiment of the present invention configured as described above is the rotation member 10, 11 by the vertical expansion force of the resilient means 50 provided on the rear side of the rotation member 10, 11. As the rear end portion is lifted, the handle members 20 and 21 are also kept a certain distance up and down, and the front sides of the rotation members 10 and 11 come into contact with each other and are provided on the front side of the rotation members 10 and 11. A pair of first and second shell opening members 40 and 41 to be also maintained in contact with each other.

Therefore, in order to dig oysters, the user is holding the front first and second shell opening members 40 and 41 with the other hand while the user wraps the rotating members 10 and 11 with one hand like the conventional auxiliary tool for oyster peeling. The closed shell can be opened by inserting it into the inside of the shell of the oyster and rotating the rotating members 10 and 11 in one or both directions.

However, since the shell of the oyster does not open easily, it is very difficult for the user to forcibly enter the first and second shell opening members 40 and 41 into the shell, and also the first and second shell opening members 40 and 41 ), it is also very difficult to open it at a suitable angle for taking out the contents provided inside the shell while turning the rotating members 10 and 11, even if the shell is entered inside.

Accordingly, the present invention is to improve the inconvenience and to make the shell easier to open, and in FIGS. 2 to 4, the shell is opened using the auxiliary tool 100 for cracking the oyster according to an embodiment of the present invention described above. The state of use is shown briefly.

That is, when performing an oyster cracking operation using the oyster cracker auxiliary tool 100 according to an embodiment of the present invention, the first and second shell opening members 40 and 41 are first handled to facilitate entry into the shell inside. After inserting a part of the shell 200 between the shell crushing members 60 and 61 provided on the inner surfaces of the members 20 and 21, the handle members 20 and 21 are pressed to cut or crush a part of the shell .

When the shell crushing members 60 and 61 come into contact with each other and cut or crush a portion of the shell 200 located therebetween by the operation of the handle members 20 and 21, a certain gap is seen between the shells made of upper and lower layers, or The first and second shell opening members 40 and 41 are inserted to a certain depth between the gaps.

Of course, after entering the pair of first and second shell opening members 40 and 41 inside the shell 200, hold the rotating members 20 and 11 and turn to open the shell, but the first and second shells Since the opening angle of the shell opened by rotating the opening members 40 and 41 is small, the inconvenience of having to hold the upper and lower shells with both hands and further spread them after the first and second shell opening members 40 and 41 rotate.

However, as shown in FIG. 3 , the present invention presses the handle members 20 and 21 after entering the first and second shell opening members 40 and 41 to a certain depth into the shell 200 with one side cut off. When the first and second shell opening members 40 and 41 are vertically spaced apart in proportion to the vertical movement distance (or height) of the upper and lower handle members 20 and 21, the shell can be easily opened.

In this way, when the shell is opened by pressing the handle members 20 and 21, the shell opening angle can also be opened at a much larger angle than the opening angle of the shell opened when the shell opening members 40 and 41 are rotated. This makes the peeling process easier.

After the shell 200 is opened, as shown in FIG. 4 , the front ends of the first and second shell opening members 40 and 41 are part of the inner surface of one shell while holding the rotating members 10 and 11 with one hand. When the shell muscle (temporal part) is cut by pushing it under the contents 250 attached to the shell, the contents are separated from the shell.

When the contents are separated from the inner surface of the shell, as shown in FIG. 5 , the contents are taken out by using the contents withdrawal hook 30 provided at the rear end of the handle member 21 and finally separated from the shell.

In this way, the auxiliary tool 100 for opening the oyster according to the present invention cuts or crushes a part of the shell before opening the oyster, and then uses the lever principle to attach the first and second shell opening members 40 and 41 to the handle member 20 ,21) makes it possible to easily open the closed shell by spaced apart through the vertical operation, and the contents attached to the inner surface of the opened shell are separated using the first and second shell opening members 40 and 41, and then the contents are taken out. Since it can be taken out of the shell using the hook 30, the conventionally difficult oyster digging operation is made more easily.

On the other hand, FIG. 6 shows the external state of the auxiliary tool 100 for cracking oysters according to another embodiment of the present invention, and FIG. 7 shows the state of the vertical cut section of FIG. 2 .

The auxiliary tool 100 for cracking according to another embodiment of the present invention has the same operation structure and configuration as the one embodiment of the present invention described above, but a pair of first and second shell opening members 40 and 41 ) on either side of the upper and lower sides, in the illustrated example, the second shell opening member 41a has a structure in which the engaging portion 43 inclined at a predetermined angle downward or upward is formed.

In particular, the fixed end side of the second shell opening member 41a on which the locking part 43 is formed has a structure in which it is elastically fixed and supported by the buffer means 15 installed in the rotation member 11, and moves after retreating a certain distance to the rear. This is stopped and made of a structure that can return to the original position when the external force is removed.

That is, in the auxiliary tool 100 for cracking according to another embodiment of the present invention, the tip ends of the upper and lower first and second shell opening members 40 and 41a made of a pair are in contact with each other to maintain a horizontal state for a certain length. Later, at a position spaced apart from the tip by a certain distance, on either side, in the illustrated embodiment, a hooking part 43 protruding downwardly on the lower second shell opening member 41a is formed, and after opening the shell, the contents 250 When separating from the inner surface of the shell, as shown in FIG. 8, only the first shell opening member 40 on which the locking part 43 is not formed is pushed under the contents 250, and the product having the locking part 43 is inserted. 2 The shell opening member (41a) is to be caught on one side of the shell border (220).

Therefore, while the second shell opening member 41a caught on the shell rim 220 cannot enter the shell any more and retreats by the compression depth of the buffer means 15, the upper first shell opening member 40 is As the inside of the shell is collected, the contents 250 are separated.

As such, in the auxiliary tool for cracking according to another embodiment of the present invention, the upper first shell opening member 40 moves toward the inside of the shell by the retreat distance of the second shell opening member 41a provided with the locking part 43 . After further entry, the operation of picking the contents is performed, and even if the operator applies excessive force during the operation, the first and second shell opening members 40 and 41 are no longer able to enter the shell, so that the operator can no longer enter the shell. To prevent a safety accident in which the hand holding the shell is injured by the blade part or the other hand applying force to the sharp edge of the shell is injured due to excessive entry of the opening member 40 .

In addition, when performing the separation operation of the contents through the left and right movement of the first shell opening member 40 that enters between the contents and the inner surface of the shell in order to remove the contents of the shell, the engaging part 43 is the shell edge part ( 220), so that the movement of the first shell opening member 40 is flexibly made so as to be able to move according to the left and right movements of the first shell opening member 40, so that a safe excavation operation is performed.
