Description

  The present invention relates to a bamboo shoot skin treatment tool for removing the skin of a relatively small diameter nematode, etc., native to Yamano.

Some conventional skin treatment tools have a movable half cylinder with two blades, an outer cylinder with one blade, and a total of three standing up inward of the cylinder. The outer cylinder and the movable half cylinder are fixed with a band. The bamboo shoots are inserted and cut by an operation by intuition (for example, refer to Patent Document 1).
Another skin treatment tool has a scissor shape instead of a cylindrical shape, but similarly relies on intuition (for example, see Patent Document 2).

  Hereinafter, a conventional skin treatment tool will be described with reference to FIGS. In FIG. 8 explaining Patent Document 1, the top of the bamboo shoot is inserted first into the insertion slot. And while adjusting or adjusting the force applied to the finger pad, the bamboo shoots are cut with three blades provided on the outer and half cylinders, and then the skin is manually removed to leave edible fruit. Is.

  In FIG. 9, the root of the bamboo shoot is placed in the guide groove 3 and cut while being pulled out. The finger is adjusted by intuition and cut into the bamboo shoots.

Japanese Patent Application 2000-353592 Reality 6-1100

  Since the bamboo shoot skin treatment tool of Patent Document 1 uses three blades, it seems to be functional and efficient at first glance, but in use, a mechanism that must apply force to the finger pad from the beginning to the end. So, beginners had the disadvantage of tearing the inside of the skin and creating uncut skin. In addition, since the three blades cut three lines, unnecessary peeling or collapse of the skin is likely to occur when the skin is removed, which is rather troublesome and cannot be performed smoothly.

  Moreover, in the instrument of patent document 2, it has taken the form which inserts a bamboo shoot in the V-shaped guide groove | channel which has a cutter, and cuts into skin | leather. However, since the shape of the V-shaped groove is fixed, there is a drawback that it escapes from the blade or is obliquely cut off depending on the diameter of the bamboo shoot.

  In order to solve the above-described problems of the prior art, the present invention has the following four problems to be solved. (1) While having a single blade, it has an unskilled function that can be cut without trouble, and devise how to remove the skin. (2) Instead of relying on the intuition to operate while applying force from the beginning to the end of the finger pad, other operation methods are incorporated. (3) To prevent swinging, the outer cylinder and the inner half cylinder (inner body) are attached not to one place but to two places on each side so as to be movable. In addition, an elastic body is interposed in this mechanism so that the half cylinder (inner body) moves up and down semi-automatically depending on the diameter of the bamboo shoot inserted. (4) In order to prevent the escape from the blade and oblique breakage seen in Patent Documents 1 and 2, a mechanism to widen or shrink the passage according to the diameter of the bamboo shoot is formed by operating the finger pad. To do.

    In taking this measure, the present invention measures the dimensions of the structure and the structure of the bamboo shoot of Nemagaritake bamboo, which is considered to be the basis for this. The length (distance) from the tip (vertex) to the edible fruit tip is approximately constant between about 7 cm and 8 cm, regardless of the individual. Moreover, since the diameter of the nematode mushroom at the actual tip position is generally constant and is 1.0 cm to 1.2 cm, at the actual tip position, if one half of the diameter is cut, the skin on one side of the skin You can cut all of them. In addition, the thickness of the skin gradually decreases as it proceeds in the root direction, and is 2 mm or less at a position 10 cm below the top, and the thickness of the skin is 0.5 mm below 20 cm. (See FIG. 5). The above are the dimensions related to the nematode mushroom, but it is also applicable to other similar bamboo shoots. However, it is necessary to increase the size of the processing tool for a 3-4 cm bamboo shoot, but it is difficult to handle a larger bamboo shoot.

  Next, means for solving the problems of the present invention will be described. The upper part of one end of a cylinder that can be gripped by a palm is cut out in a U shape to form an outer cylinder having an opening, and one cylinder having an outer diameter smaller than the inner diameter of the outer cylinder is provided. The inner body having a length substantially equal to the outer cylinder is formed so that the width thereof gradually decreases toward the end of the inner cylinder, and the wide end of the inner body is opposite to the opening. Match the curved surface to the upper wall inside the outer cylinder that becomes the end, and attach the side parts movably with stoppers such as eyelets and rivets, and between the outer cylinder and the inner body Interposes an elastic body that constantly applies a downward force to the internal body.

  Also, the other end of the inner body, which is narrower in width, is positioned in the opening of the outer cylinder, a cut is made in the center of the end of the inner body, and a single blade with the blade tip facing downward is fitted into this. The upper part of the blade is fitted into a blade holding part provided on the upper part of the inner body, and is detachably fixed by a fastener such as a bolt or nut.

    In addition, a finger pad is attached to the upper part of the blade holding part, and a bamboo stool that holds down the bamboo stool is formed below the blade holding part in an umbrella-like cross section on the left and right sides of the blade, and an insertion path for the bamboo sword is formed. In addition to forming a presser foot, the guide body indicating the position of the actual tip of the bamboo shoot is attached to any one of the outer cylinder side surface at the end of the opening, the finger pad, the blade holding portion, etc. To do.

  The configuration of the present invention is as described above, and the operation thereof will be described below. When using the present invention, as shown in FIGS. 6 (1) to (4) (in the case of a right-handed person), hold the skin treatment tool with the left hand, and the bamboo foot presser will stick to the lower part of the outer cylinder with the thumb. While pushing the finger pad, insert the bamboo shoot with the right hand with the top of the insertion port first.

  The bamboo shoot is a blade that is integrated with the inner body, and the skin is cut and comes out of the insertion passage surrounded by the outer cylinder and the bamboo shoot retainer. When the diameter is 10 mm to 12 mm and the diameter is larger than this, the bamboo shoot presser is lifted, and it can be seen that the actual tip has come to the position of the blade. (See FIG. 2). The finger pad is pressed only in the section from 7 cm to 8 cm from the top of the skin with no fruit. After that, the thickness of the skin gradually decreases, and is less than 2 mm at 10 cm from the top (0.5 mm at 20 cm). Therefore, the thumb is released from the finger rest plate, and a cut is made by the elasticity of the elastic body installed between the outer cylinder and the inner body. This is a feature of the present invention in the way of cutting with a feeling that the present invention is not skilled.

    Therefore, in the present invention, knowing the position of 7 cm to 8 cm from the top of the nematode mushroom is the key to work, so as a clue to know the position, a plate-shaped or bar-shaped reference body is attached to the front of the skin treatment tool. When it is attached to a required point (for example, an outer cylinder, a finger pad, etc.) by projecting 7 cm to 8 cm forward, when the top of the bamboo shoot coincides with the tip of the reference body, it is time to release the thumb from the finger pad. (See Figure 6)

  As described above, the present invention is a method in which a single cut is made in the bamboo shoot. When the skin is peeled (removed) by this, as shown in FIG. 7, about 7 cm to 8 cm from the top of the bamboo shoot. Bend it to the incision side to open the skin, put your finger in this to separate the skin from the fruit, and peel off the entire skin at once.

  The present invention investigated the problems of the prior art and the composition of the fruit and skin of bamboo shoots of Nemagaridake, and tried to realize a skin treatment tool having a configuration suitable for it. In particular, the blade for cutting into the skin of bamboo shoots It aims at the realization of the instrument which can carry out the peeling work simply, accurately and efficiently. Since the diameter of the bamboo shoot at the actual tip is 1.0 cm to 1.2 cm, the height of the blade is set to 5 mm to 6 mm so that it is not cut too much and is surrounded by the outer cylinder and the bamboo shoot presser. The height of the insertion path is 1.0 cm to 1.2 cm, and only one side of the bamboo shoot can be cut at maximum. Furthermore, there is no fruit between 7cm and 8cm from the apex, and only the skin is applied. In this section, force is applied to the finger pad, and the blade is cut into the bamboo shoots. As the thickness is reduced, the thumb is removed from the finger rest plate, and the blade gradually bites in as it is inserted. The blade gradually becomes shallower and can be cut with only a small force of the elastic body (spring, etc.) installed in the internal body. And its functions and effects are unparalleled. (See Figs. 4 and 5)

    In addition, as a means of knowing the position of 7 cm to 8 cm from the top of the bamboo shoot, a standard body consisting of a plate or a rod protruding outward from the opening end and its adjacent portion is provided, and 7 cm to 8 cm without depending on intuition. After the position, the mechanism that can accurately change the depth of cut with respect to the skin simply by removing the thumb from the finger pad is a major feature of the present invention (see FIGS. 1 and 6).

Also, in the present invention, shaft holes are provided at two locations on each of the outer cylinder and the side part of the inner body, and this is movable, so that the inner body does not swing when the skin is cut. Unlike Patent Document 1 in which only one portion is stopped by a belt, there is an advantage that uneven cutting is less likely to occur, overcutting, or slanting (see FIGS. 1 and 3). Furthermore, in the present invention, since the inner body is movably mounted in the outer cylinder, the inner body automatically moves in accordance with the difference in the diameter of the bamboo shoot, and the bamboo shoot retainer and the outer cylinder appropriately provide the insertion path for the bamboo shoot. Since it is made, there is little sway, and therefore the notch is also appropriate (see FIG. 2).

    Since the present invention is implemented with a single blade that cuts into the skin of a bamboo shoot, the problem as in Patent Document 1 does not occur, and after a single cut is made, FIGS. 7 (1) to (3) As shown in Fig. 4, the skin can be easily removed by bending a portion 7 cm to 8 cm from the top of the bamboo shoot to the cut side, putting a finger into the open mouth and applying force in the left-right direction. This effect can be removed more accurately and more cleanly than the means for removing the skin by making three incisions, and is a great effect due to the configuration and function of the present invention. The structure and function of the skin treatment tool of the present invention can be carried out in about 10 seconds from the cutting of one nematode mushroom to the removal of the skin. This workability achieves the intended purpose.

    Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes an outer cylinder that constitutes an outer shell of the present invention and supports an internal mechanism. The outer cylinder 1 is a cylinder, and in the case of the nematode mushrooms, the diameter is approximately 3 cm, the length is approximately 8 cm, a U-shaped notch is formed in the upper part of one end, and an opening 2 is formed. The end opposite to the opening 2 serves as an insertion port 11, and shaft holes 13A through which the fittings 8 and the like are inserted are provided on both sides thereof. The material of the outer cylinder 1 is preferably a metal. In FIG. 1, a translucent plate is attached to the finger rest plate 6 as a guide body 9 so as to protrude 7 cm to 8 cm.

3 in FIG. 1 is an inner body whose length is substantially equal to that of the outer cylinder 1, and a metal cylinder having an outer diameter smaller than the inner diameter of the outer cylinder 1 is directed from one end to the other end, and is shown in FIG. Thus, the width is divided vertically into a shape that gradually decreases in a tapered shape. The inner body 3 is formed by combining two plate-like bodies with the blade holding portion 4 of the blade 7 on the upper surface of the end portion where the width is narrow, and a finger pad 6 is attached to the upper portion thereof by spot welding. The lower part of the blade holding part 4 is configured so as to be a bamboo keeper 10 having an umbrella-shaped cross section. The blade 7 is clamped with a bolt and a nut as a stopper 5 after being sandwiched between the blade holding portions 4 and attached. Therefore, the blade 7 is detachable. In addition, the protrusion of the blade from the blade holding part 4 is 5 mm to 6 mm, and the height H of the insertion path surrounded by the outer cylinder and the bamboo shoot presser is 1 cm to 1.2 cm as shown in FIG.

  Further, shaft holes 13B corresponding to the shaft holes 13A of the outer cylinder 1 are formed on both sides of the wide end portion of the inner body 3, and a spring hooking hole 14 is provided above the center from this. .

    After the inner body 3 is configured as described above, the outer body 3 is narrow so that the narrow end portion is on the opening 2 side of the outer cylinder 1 and the wide end portion is on the insertion port 11 side. After being accommodated in the cylinder 1, the upper portions thereof are aligned with each other. Next, the shaft holes provided on the left and right sides of the outer cylinder 1 and the inner body 3 are aligned with each other. The inner body 3 is fastened to be movable. At this time, as shown in FIG. 4 (B), made of stainless steel having a diameter of 0.6 mm, the one-time half-winding spring 15 is added one by one to the left and one at a time, and the inner body 3 is always subjected to downward force. To be.

  In addition, although the case where a spring is used as an elastic body has been described above, a coil spring or a leaf spring may be provided between the outer cylinder 1 and the inner body 3, or a soft rubber or the like is bonded. It may be a thing. However, it should not be too much stronger than the elastic force of the winding spring in FIG. 4B, but it should not be much weaker. This is an inherent elastic force for embodying a skin treatment tool for non-experienced nematode mushrooms.

  The above is the best mode for carrying out the present invention, but its operation is clearly described in the above-mentioned means for solving the problems, and therefore description thereof is omitted here.

  Although not shown in the present invention, as another embodiment of the present invention, a blade opposed to the blade 7 attached to the inner body 3 is attached to the inner wall of the outer cylinder 1, and a total of two blades are used. The constructed bamboo shoots are also acceptable. Thereby, in the removal of the skin, the efficiency of the work of separating the skin left and right is improved.
