Description

  The present invention relates to a picker that is used when harvesting only vegetables, fruit trees, etc. Specifically, it is easy to cut Kaga et al. With one hand, and it is excellent in safety that the cutting edge does not interfere with fingers etc. It is about a vessel.

  In recent years, the number of agricultural workers has been decreasing along with the decrease in the number of farmers. This is a tendency common to Western countries and the like, but in Japan, not only the decrease but also the aging is advancing at the same time, which is a big problem. It can be said that these causes lie in the youth's farming away from farming. One of the factors is the labor burden in agricultural work. Artificial picking work is especially necessary for harvesting citrus fruit trees that cannot be relied on with agricultural machinery, and the work of harvesting fruits grown in high places from below is done with arms and shoulders. For example, there is a problem that a large burden is imposed on the body and the burden of physical labor is large. In other words, there is a long-awaited proposal for a technique for preventing young people from leaving agriculture and reducing the burden on agricultural workers who are aging.

  In addition, lemons and mandarin oranges that grow well on well-drained soil are often harvested on steep slopes of mountains that have an inclination angle of 30 degrees or more, so fruit trees grown in greenhouses and flat soils. Unlike the harvesting work in the garden, etc., the scaffolding is unstable and the workability is poor. Therefore, the harvesting method that requires both hands is dangerous and it is difficult to say that safety is ensured.

  In order to solve these problems, various techniques have been conventionally provided. For example, “a cylindrical portion that can be inserted and fixed to the thumb, a flat support portion that extends from the cylindrical portion in the outer peripheral direction, a notch portion formed at the tip of the support portion, and the notch There is a picking device for vegetables and the like characterized by comprising a blade portion fixed to the inner back portion of the portion (see Patent Document 1). However, this technology is a technology related to a plucking device suitable for fruit picking work for thinning out fruits, and in the state of picking with the thumb and index finger, the blade tip is pressed against the finger and cut off, so the risk of cutting the fingertip is completely eliminated. It cannot be said that they have been removed.

  In addition, an inexpensive finger-mounted harvesting nail that is safe because the blade portion appears to be exposed on the upper surface, is easy to polish the blade portion, and can be used repeatedly is also provided (see Patent Document 2). This technology is safe because the blade edge is not pinched by a finger, but since the metal blade is prepared in a state bent at 90 degrees with respect to the thumb, if a large force is applied, stress concentrates on the base part of the metal blade, causing bending. It is thought that it is easy to cause deformation.

  In addition, in the finger cutting scissors for cutting vegetables and fruits to be inserted into the index finger, the index finger insertion part is configured in a ring shape, and the cutting blade insertion is configured in a replaceable blade system downward from the index finger insertion part. The razor blade can be inserted into and removed from the cutting blade insertion groove provided in the cutting blade insertion portion, the center of the ring-shaped cutting blade side insertion portion for inserting the index finger, and the cutting direction of the razor blade Has also been proposed (see Patent Document 3). However, in such a technique, the blade tip is pressed against the finger in a state where the finger is picked with the thumb and the index finger, and the risk of cutting the finger tip remains.

  In addition, `` It is a knob for attaching to the thumb and picking with one hand and performing a fruiting operation, and a cylindrical portion that can be inserted into the thumb and fixed, and protrudes outward from the outer periphery of the cylindrical portion, A knob with a cutting blade formed so that a direction in which the blade tip extends is inclined to either the right side or the left side when viewed from the axial direction of the cylindrical portion toward the blade tip. According to the plucking device, a technique has been proposed that can easily cut with a hand posture with its arm protruding naturally, and can cut the fruit branch without putting too much force on the finger ( (See Patent Document 4). However, in such a technique, the blade edge exists on the extension of the nail of the thumb, but since the holder part is held between the interphalangeal joint of the thumb and the metacarpophalangeal joint, the fingertip force is difficult to enter, You can't get a sense of cutting with your toes.

  In addition, any of the above inventions or devices is based on picking with the force of the fingertips, and the labor load is large, and there is a drawback that it is impossible to work with one hand in an unstable work state due to steep inclination. Yes.

  In addition, before completing the invention of the present application, the present inventor, as a picking device that can be used with one hand, is a picking device composed of a finger sack to be fitted and a finger band to be fitted to the index finger, A holder for mounting a replaceable blade body on the top, and the blade body mounted on the holder is provided on a substantially extension extending from the base of the thumb nail toward the tip of the nail, and the shape of the blade edge is In addition, the whole from the tip to the base is curved in a convex arc shape on both sides below the center portion, and the cutting edge has a convex arc shape on the back and left and right around the tip, and the finger band is A sheet for receiving the blade tip is attached to the middle phalanx region, the finger sack is fitted to the thumb, the finger band is fitted to the index finger, and the IP joint (interphalangeal joint) between the distal phalanx of the thumb and the middle phalanx Was bent at approximately 90 degrees In the state, a utility model right has already been acquired for the picking device characterized by adopting an arrangement in which the cutting edge of the blade body is substantially perpendicular to the sheet of the finger band, and the technology has been disclosed ( (See Patent Document 5).

  Unlike the technique described in Patent Document 3, this technique enables a plucking operation as if it were cut off with its own nail tip by providing a blade portion for plucking on the extension of its nail. It is a picker, excellent in working feeling, and easy to cut because the fingertip force acts on the cutout efficiently. However, because it is sandwiched between the thumb and forefinger, the blade tip is pressed against the finger and cut off, so it cannot be said that the risk of cutting the finger tip is completely removed, and basically the force of the fingertip is used, It can be said that there was a problem that a large joint such as a wrist can be easily picked with less force.

  Therefore, the present inventor has completed a safe picking device according to the present invention that enables safe picking of fruits or the like with one hand with less force.

The finger sack portion 30 includes an index finger sack 40 configured to fit between a metacarpophalangeal joint (MP) of the index finger and a proximal interphalangeal joint (PIP), and a metacarpophalangeal joint (MP) of the middle finger. To the proximal interphalangeal joint (PIP), and the index finger sack 40 and the middle finger sack 50 are suspended via the blade body 20 so as to be suspended therebetween. It is the biggest feature that it is connected. Embodiments will be described below with reference to the drawings.

  FIG. 1 is an explanatory diagram of the overall configuration of a picker 10 according to the present invention. FIG. 1A shows a blade body portion so that two finger sack portions 30 of an index finger sack 40 and a middle finger sack 50 are suspended. FIG. 1B shows a basic overall configuration in which the picker 10 according to the present invention is configured to be held by two fingers of the index finger and the middle finger, and FIG. The connecting finger sack portion 32 connected to the ring finger sack 60 and the index finger sack 40 are connected via the blade body 20 so as to suspend them, and the picker 10 according to the present invention includes the index finger, the middle finger, and the ring finger 3. A basic overall configuration in the case of a configuration held by a finger is shown.

  The finger sack portion 30 is a cylindrical body for holding the picker 10 according to the present invention through the operator's finger. The material is leather, synthetic leather, fiber-based material, plastic, etc. A material having hardness and elasticity that can be slightly deformed by the force of the wrist or wrist is used. In the case where the finger sucker 30 is configured to hold with two fingers, as shown in FIG. 1A, the holder 22 is provided between the index finger sucker 40 and the middle finger sucker 50, and is held with three fingers. In the case of the configuration, as shown in FIG. 1 (b), in addition to the configuration in which the holder 22 is provided between the index finger sack 40 and the middle finger sack 50, a linked finger sack 60 in which a ring finger sack 60 is further connected to the middle finger work 50. Part 32. The length of each sac is a length of a configuration that fits between the metacarpophalangeal joint (MP) and the proximal interphalangeal joint (PIP). Regarding the inner diameter, there are individual differences in the thickness of the user's finger, so it is desirable to prepare various sizes.

  FIG. 2 is an explanatory diagram of the configuration when a slit is used in the sack portion according to the present invention. FIG. 2A shows a state in which the slit portion 31 is further provided in the case of the sack portion 30 configured to be held by two fingers by the two sack of the index finger sack 40 and the middle finger sack 50. (B), in addition to this, in the case of the sac portion 30 configured to be held by three fingers by three sac to which the ring finger sack 60 is further added, each of the states in which the slit portion 31 is further provided. Show.

  As described above, the finger sack portion 30 is formed using an elastic material, and as shown in FIG. 2, as shown in FIG. It is also effective to adopt a configuration that contributes to improvement. In addition, although the state which has provided the slit which concerns on all the sack parts 30 in all is shown in drawing, this is an illustration and does not show a limiting requirement by this drawing. The same applies to the arrangement position of the slit portion 31.

  FIG. 3 is an explanatory view of the configuration when the index finger sack 40 according to the present invention is provided with the opening / removal opening 41, and FIG. 3 (a) shows the index finger sack 40 provided with the opening / detachment opening 41 on the thumb side surface. FIG. 3B shows a state in which the attaching / detaching opening 41 is further provided with a mounting state adjusting mechanism 42.

  In the case of adopting the configuration in which the opening / closing part 41 for attachment / detachment is employed, since the side part of the index finger sack 40 can be greatly opened, only the index finger can be removed even after being worn once, and the movement of the fingertip is restricted. It is easy to leave the free state. In particular, if the handle K1 is thin and the picking force is small, the holding / fixing force to the hand H of the picking operator may be small, so the area of the opening is increased to increase the ease of attachment / detachment. Is also effective.

  On the other hand, when the fruit handle K1 is thick and hard, a holding / fixing force to the hand H of the plucking worker is required. Therefore, if the configuration having the mounting state adjusting mechanism 42 as shown in FIG. 3B is adopted, the finger fits, there is no play in the movement of the finger in the sack, the feeling of use, how to apply force, etc. Work efficiency is improved.

  In FIG. 3 (b), as the mounting state adjusting mechanism 42, the belt 45, which is fixed to one end of the opening, is protruded and folded back via a hook 44 provided on the other end side, and a magic tape (registered trademark) is obtained. ) Etc., the embodiment fixed by the surface fastener 43 is illustrated. However, the mounting state adjusting mechanism 42 according to the present invention is not limited to this, and for example, by using the elastic force of the material of the sack portion 30, a zipper or other line fastener, a string body, or a hook or button It may be something that locks. Alternatively, it is possible to adjust the tightening force in the mounted state by using an elastic member for the string body or the hook itself. In the drawing, the position where the hook-and-loop fastener 43 such as Velcro (registered trademark) is shown appears to be affixed to the outside of the belt 45 and the inner side of the index finger sack 40. Is the opposite side. This is shown as a reference for the approximate arrangement position.

  FIG. 4 is a configuration explanatory view of the blade body portion 20 of the picker 10 according to the present invention. The upper right figure in the figure shows a cross section of the AA part, and the lower figure shows that the blade body part 20 is connected so as to be suspended between the finger sack. The blade part 20 is a blade part for cutting a fruit handle K1 extending between the fruit axis K2 and the fruit K for picking the fruit K or the like. A material for a general blade may be used as the material for the blade body portion 20. For example, steel or carbon steel. In addition, it is desirable to use a metal with excellent corrosion resistance such as stainless steel and titanium in consideration of maintenance due to rust, etc. Furthermore, ceramic blades and single crystal silicon, which are difficult to reduce sharpness, are effective although they are expensive. . As for the shape, the shape of the blade edge 21 has a shape that is curved in a substantially U shape toward the base of the finger on a flat plate material. In some cases, the blade edge 21 may be the index finger sack 40 and the middle finger sack. It is also effective to use the blade body portion 20 having a configuration in which an inclination angle that inclines from the longitudinal direction of 50 toward the palm direction is provided.

  In addition, although it has shown on drawing so that the holder 22 used as the blade body part 20 attachment position is offset and attached to the fruit K side, if it arrange | positions in the center position between the suspended finger sacks 30, it will be right. Regardless of whether you are handed or left-handed, you can use either the left or right hand H. If you want to improve versatility, place the holder 22 at the center. However, when the blade part 20 is offset and attached to the fruit K side as shown in FIG. 4, the fruit handle K1 can be cut short, and the fruit handle K1 is cut at a short position from the fixed end of the fruit K1. This is effective in that it can prevent the deterioration of the cutting property due to the elongation and bending of the steel.

  It is also desirable for the blade body 20 to adopt a configuration in which the holder 22 is provided between the index finger sack 40 and the middle finger sack 50 and can be exchanged through the holder 22. For example, there is a structure in which it is inserted into a holder 22 in which a groove for inserting the blade body portion 20 is formed between the index finger sack 40 and the middle finger sack 50 and fixed with a fixing screw 24. When the sharpness is deteriorated, it is possible to reduce the time that hinders the work by replacing only the blade body 20.

  The blade edge portion 21 is a blade formed in the blade body portion 20 in a substantially U-shape. Most of the picking devices described in the prior art documents related to the prior art are sandwiched by using the abdomen of the fingertip, and since the cutting direction is perpendicular to the blade of the blade, only force is required. There were many things that could not be cut well. The reason why the cutting edge portion 21 according to the present invention is made substantially U-shaped is that the cutting edge 21 is cut straight while sliding the outer peripheral edge of the fruit handle K1 even when the cutting tool is pushed straight into the fruit handle K1. Even the fruit pattern K1 exhibits the effect of facilitating cutting.

Next, wearing of the knob 10 according to the present invention will be described.
Each finger is inserted into the index finger sack 40, the middle finger sack 50, or each finger sack of the ring finger sack 60 and the ring finger sack 60. (PIP) to fit in. In addition, in the picker 10 having the structure having the attachment / detachment opening 41, the middle finger and the ring finger are first inserted into each of the other finger sacks while the attachment / detachment opening 41 of the index finger sack 40 is opened to the thumb side. Finally, the index finger is mounted so as to be closed in the index finger sack 40 from the opening 41 for attachment / detachment. Further, in the configuration having the mounting state adjusting mechanism 42, for example, a band 45 to which either a loop surface or a hook surface of a hook-and-loop fastener such as Velcro (registered trademark) is attached is connected via a hook 44. Then, it is folded at a position where an appropriate fixing force is obtained, and locked to either the loop surface or the hook surface attached to the index finger sack 40.

  FIG. 5 is a basic usage explanatory diagram of the picker 10 according to the present invention. At the time of picking, it is fundamental to cut straightly so that the cutting edge 21 enters the fruit handle K1 vertically. The direction is the same as the direction toward the tip of the fruit axis K2, as shown in FIG.

  6 and 7 show another cutting method when the fruit handle K1 is long and it is difficult to cut it simply by pulling the fruit handle K1, even if the fruit handle K1 is pushed straight, and FIG. Shows each state as seen from the side. In either case, as shown from (a) to (c), the wrist 22 is cut back from the state in which the cutting edge 22 bites into the fruit handle K1. The movement is such that it goes outward from the direction of the fruit axis K2.

  The plucking device 10 according to the present invention exhibits a particularly excellent effect in the harvesting work of citrus fruits as represented by the fruit K shown above. Moreover, since it can be used not only as a contributor to the picking work of fruit K that grows on citrus fruit trees, but also as a picker for vegetables grown in fields such as eggplants and peppers, its industrial applicability is great.
