1 is a view showing a tap opener according to a first embodiment of the present invention.

The tap opener 100 includes a blade 110, a blade fixing part 120, a finger fixing part 130, and a rotating fixing part 140.

The blade 110 has a sharp surface at the front end portion so as to easily cut the nipple, and is inserted and fixed in the blade insertion portion 122 of the blade fixing part 120. The blade 110 is replaceable by the user.

The blade fixing part 120 includes a blade inserting portion 122 into which the blade is inserted, and the blade inserting portion 122 is inserted into and fixed to the blade inserting portion 122. The blade fixing part 120 is connected with the finger fixing part 130 and may be configured in one piece.

Here, the blade fixing part 120 is connected to the finger fixing part 130 at an oblique angle a. When the blade fixing part 120 is integrally formed with the finger fixing part 130, as shown in FIG. 1, a material such as an iron plate protruding from the finger fixing part 130 is folded up in the direction in which the blade is inserted. It can be manufactured.

In one embodiment, the front end portion of the blade 110 is preferably located inside by a predetermined length than the front end portion of the blade insertion portion 122. The blade 110 protrudes from the blade insertion portion 122 so that a sharp surface is exposed to the outside to prevent the user from being injured.

The finger fixing part 130 is a space into which the thumb is inserted, and is preferably annular so that the thumb can be properly inserted. It is preferable that the length D of the finger fixing part 130 does not exceed the length of the first node of the thumb so that the thumb can be easily moved, and generally 5 mm to 15 mm.

In an embodiment, the finger fixing part 130 may have a shape in which the front portion is partially blocked. This is to prevent the thumb from being pushed forward during operation.

The blade fixing part 120 and the finger fixing part 130 can be manufactured from plastic, reinforced plastic and steel plate, and can be manufactured integrally with injection, casting, sheet metal, and the like.

Rotational fixing part 140 serves to fix the vegetable tap opener to the end of the thumb inserted into the finger fixing part 130. Rotation fixing part 140 is an annular portion 143 that is fitted in an annular annular shape between the first and second nodes of the thumb and the extension portion for connecting the annular portion 143 to the finger fixing portion 130 ( 145). The annular portion 143 has a suitable width so that its cross section is positioned between the first and second nodes of the finger. This width is preferably smaller than the width of the first section. Extension portion 145 is bent in the front end vertically is inserted into the fixing hole 142 of the finger fixing part 130, it is rotatable in the fixing hole 142.

2 is a view showing a method for cutting vegetables using a tap opener according to the present invention.

The thumb of the user is inserted into the finger fixing part in such a state that the blade of the tap opener 200 is positioned on the thumb of the user. The user grabs the vegetable 240 using the remaining four fingers, and as a result, the vegetable 240 is inserted between the remaining four fingers of the user. When the user advances the finger in the direction of movement m, the stem of the vegetable is cut off.

In FIG. 2, the angle a represents an angle formed by the finger fixing part 130 and the blade fixing part 120, and is inclined obliquely so that the blade is perpendicular to the vegetable when the user grabs the vegetable. If the blade is perpendicular to the vegetables, the stem of the vegetables can be cut in the shortest distance. In a preferred embodiment, this angle a is between 15 and 30 degrees.

In Fig. 2, the protruding length b of the blade (the length from the front end of the user's finger to the front end of the blade) is sufficient to have a sufficient margin for picking the stem of the vegetable. If it is too short, there is a problem that the entire tap of the vegetable is not cut, if too long it is inconvenient for the user to move the tap opener. In a preferred embodiment, the protrusion length b is 10-15 mm.

The width of the blade is sufficient to be long enough to pinch the vegetables, in a preferred embodiment is 15 to 20 mm.

As shown in Figure 2, using the tap opener according to the present invention, since the vegetables can be cut to the tap of the vegetable using the grabbed hands in the state of grasping the vegetables, the efficiency of harvesting vegetables increases . In other words, efficiency can be doubled because the hand and the hand that can grab the vegetables can be eliminated with one hand, and the hand that does not grab the vegetable can be emptied to perform other tasks at the same time. Applicants' efficiency experiments showed that the time and labor efficiency of the harvesting operation increased by about 40%.

In addition, using the vegetable tap opener according to the present invention, since the annular portion 143 (Fig. 1) of the rotation fixing part 210 has a width smaller than the first node of the thumb is fixed to the thumb more firmly In addition, since the rotation fixing part 210 is rotatably connected to the finger fixing part through the extension part 145 (FIG. 1), detachment is very easy. Since the detachment of vegetable tapers occurs several times in actual vegetable tapping operation, this ease of removal greatly increases the time and labor efficiency of the picking operation.

In addition, the rotation fixing part 210 is formed of a deformable and elastic material such as steel, it can be used to deform according to the user's various finger thickness. In this case, since the rotation fixing part 210 is connected to the finger fixing part in the form of being inserted into the fixing hole, the manufacturing process of connecting the rotating fixing part to the finger fixing part is also easy due to the characteristics of the material.

3 is a view showing various forms of a finger fixing part.

Figure 3 shows a cross section of the finger fixation when viewed from the back of the opener.

The finger fixing part 310 of a 1st form is flat upper part, and lower part is annular shape. Since the upper part is a shape in which the blade fixing part is extended, it is easy to manufacture when manufacturing integrally. The lower part of the annular shape is for a close contact with the finger.

The finger fixing part 320 of the second form has an annular shape in its entirety. By forming the entire cross section of the finger fixing part in an annular shape, the finger fixing part can be more closely attached.

The third type finger fixing part 330 has a spaced part 332 at the bottom thereof. This is to adjust the size of the finger fixing portion according to the size of the finger. In one embodiment, the spacing 332 is about one third of the length of the annular direction (circumferential direction) of the finger holding portion 330.

In addition, in one embodiment, the finger fixing portion 310, 320 may be formed integrally with the thimble or gloves. The shape of the thimble and the glove is known, and the shape of the finger fixing part is as shown in Figs.

In this case, when formed integrally there is no need to provide a separate equipment for protecting the user's fingers, such as a separate glove.

4a and 4b is a view showing a plan view and a rear view of the rotation fixing part of the present invention.

The length l of the extension part 145 of the rotation fixing part 140 is the first section of the thumb of the user's thumb after the ring fixing part 130 is inserted into the thumb. It is long enough to be placed between and the second segment. Since a human finger has a thick node and a bone portion connecting the node and the node, the annular part 143 is positioned between the node and the node, and the width of the annular part 143 is made smaller than the first node. This is because the vegetable taper can be more firmly fixed to the force exerted by the direction of the work. In one embodiment, the length l is about 1.5 ~ 2.5 cm.

The width w of the annular portion 143 is smaller than the width of the first segment of the user's thumb and larger than the finger thickness between the first and second segments of the user. This is for tight fixation as described above.

The annular portion 143 and the extension portion 145 are connected at the middle portion of the annular portion 143. In one embodiment, as shown in Figure 1, when the end of the annular portion 143 is connected and manufactured integrally with the extension portion 143 in one round bent shape can be manufactured to the rotation fixing portion 140 as a single member There is a manufacturing advantage.

5 is a view showing the end of the extension of the rotation fixing part 145 of the present invention is inserted into the fixing hole 142.

The end 512 of the extension 145 is inserted into the fixing hole 142 after being substantially vertically bent.

In one embodiment, the fixing hole 142 is formed by a predetermined height h1 than the plane of the finger fixing. At this time, it is preferable that the height h2 of the extension portion protruding from the fixing hole is smaller than the height h1 of the fixing hole. This is to prevent the tip from sticking out of the finger fixing part and touching the user's finger.

6 is a view showing a vegetable tap opener according to a second embodiment of the present invention.

In the embodiment of Figure 6, the blade is formed to be inclined by a predetermined angle b rather than formed horizontally on the cutting surface.

When the cutting plane is formed horizontally, the cutting plane is shortest but has a disadvantage in that a force for cutting is required. In order to solve such a problem, in the embodiment of FIG. 6, the cutting edge is reduced by forming the surface of the blade to be inclined by a predetermined angle b from the cutting surface of the vegetable. In other words, it has a writing effect as well as a breaking effect. In one embodiment the angle b is between 35 and 45 degrees.

In addition, when forming the blade surface inclined as shown in Figure 6 has the advantage that can utilize the existing cutter blade. The blade of an existing cutter (available at a general stationery store) is formed with a cut so that it can be cut and used for a predetermined length, and the wound is inclined at a predetermined angle with respect to the cut surface. Therefore, in the case of forming the cutting surface to be inclined as in the present invention, there is an advantage that it is only necessary to cut the blade of the existing cutter by a desired length.

7 is a view showing a vegetable tap opener according to a third embodiment of the present invention.

The tap opener of FIG. 7 is an embodiment in which a blade stopper 740 is added to the tap opener of FIG. 1. The blade stop part 740 is formed to protrude between the finger fixing part 730 and the blade fixing part 720, so that the blade 710 stops from entering any more.

By the blade stop 740, the user can prevent the blade from being pushed in during operation.

In one embodiment, the blade stop 740 is configured to stop only a portion of the cross section of the blade. This is to ensure a space for pushing the blade more easily forward in the rear direction of the tap opener as shown in Figure 5, when changing the blade.

So far I looked at the center of the preferred embodiment for the present invention. Those skilled in the art will appreciate that the present invention can be implemented in a modified form without departing from the essential features of the present invention. Therefore, the disclosed embodiments should be considered in descriptive sense only and not for purposes of limitation. The scope of the present invention is shown in the appended claims rather than the foregoing description, and all differences within the scope will be construed as being included in the present invention.

As described above, according to the present invention, by forming the finger fixing part in a rotatable annular shape, not only can the vegetable taper be more firmly fixed to the user's finger but also can be easily attached and detached, thereby increasing the work efficiency.

In addition, since the blade surface of the vegetable tap opener is inclined at a predetermined angle with respect to the cutting surface, the force required for cutting is reduced.
