The picker 1 according to the present invention is used by being fixed to a plurality of fingers excluding the thumb, including at least an index finger and a middle finger.
<Example 1>
1. Picker 1
The picker 1 of Example 1 mainly has a holder part 3, a blade body part 5, and a band part 7 (FIGS. 1 to 4).
(1) Holder part 3
The holder portion 3 is made of resin, for example, made of PET, polyethylene, polypropylene, etc., and the blade portion insertion groove 11 for inserting the blade portion 5 and the blade portion 5 are screwed with screws 15. It has a screw hole 13 for wearing (FIG. 1).
(2) Blade part 5
The blade part 5 is a thin plate made of metal, for example, stainless steel that does not easily rust. The cutting edge 21 of the blade body portion 5 has a shape that is concavely curved in the inner direction. By making the cutting edge 21 into a shape that curves inwardly in a concave shape, it is possible to easily and reliably perform the abutment operation and subsequent cutting operation on the fruits and vegetables to be harvested.

  Further, the blade body portion 5 has a plurality of, for example, three screw insertion holes 25 a to 25 c to be screwed after being inserted into the holder portion 3. Here, when the screw 15 is inserted into the screw insertion hole 25b and screwed into the screw hole 13 of the holder portion 3, the projecting dimension of the cutting edge 21 that can be harvested universally regardless of the type of vegetables or fruits (for example, The protruding portion of the blade edge 21 from the holder portion 3 can be 10 mm) (FIG. 1).

  On the other hand, when the screw 15 is inserted into the screw insertion hole 25a and screwed into the screw hole 13 of the holder part 3, the protruding dimension of the blade edge 21 can be shortened (for example, the protruding part of the blade edge from the holder part 3 is 7 mm). Further, when the screw 15 is inserted into the screw insertion hole 25c and screwed into the screw hole 13 of the holder part 3, the protruding dimension of the blade edge 21 can be increased (for example, the protruding part of the blade edge from the holder part 3 is 15 mm).

  That is, it is possible to change the projecting dimension of the blade edge 21 of the blade body portion 5 depending on the type of vegetables and fruits to be harvested. Therefore, a single picker 1 can be used to harvest a variety of vegetables and fruits. Further, when the blade becomes spilled or rusted with the passage of time of use, and the sharpness becomes dull, it is possible to replace only the blade body 5 by removing the screw 15.

  Therefore, when the present invention is used, it is possible to freely change the projecting dimension of the blade edge 21 and it is easy to replace only the blade body 5, and as a result, a low-cost and easy-to-use knob 1 is provided. can do.

  Further, a cap mounting hole 23 was formed near the tip of the blade body 5 (FIG. 1). The cap portion mounting hole 23 is intended to protect the safety of preventing the blade body portion 5 from being exposed when not in use, and specifically protects the thumb when not in use.

Then, corresponding to the screw insertion holes 25a to 25c to which the blade body part 5 is screwed, the three projection parts 41a are arranged at corresponding positions inside the cap part 9 so as to be fitted to the cap part mounting hole 23. (FIG. 1 does not show the protrusions 41b and c). In the enlarged view of the cap portion 9 in FIG. 1, only the case where the screw insertion hole (short) 25 a of the blade body portion 5 is screwed to the holder portion 3 is illustrated.
(3) Band part 7
The band part 7 is mainly formed by a fastener 31 and a band 33a having a non-slip process on the back surface, for example, a non-slip rubber 33b. Even if the holder portion 3 firmly fixes the band portion 7, the holder portion 3 rotates little by little while the work is proceeding. In order to prevent this rotation, a non-slip rubber 33b is provided on the back side of the band portion 7 (FIG. 1).

  For example, a hook-and-loop fastener 35 composed of a pair of a hook 37 and a loop 39 is used as part of the band 33a as a fixing means for firmly fixing to a plurality of fingers including the index finger and the middle finger. (FIGS. 1 and 2).

The band part 7 is used in a state of being fixed to the holder part 3 by, for example, an adhesive or heat welding. That is, the band portion 7 has a hook-and-loop fastener 35 for firmly fixing the holder portion 3 to which the blade body portion 5 is screwed to at least a plurality of fingers including the index finger and the middle finger. (FIG. 2). By using this hook-and-loop fastener 35, the operation of attaching and removing the picker 1 is facilitated.
(4) How to use the picker 1 The holder part 3 to which the blade part 5 is screwed is firmly fixed to a plurality of fingers including the index finger and the middle finger by the surface fastener 35 of the band part 7. As an example, as shown in FIG. 3, the picker 1 is firmly fixed to the proximal phalanx portions of the three fingers of the index finger 53, the middle finger 55, and the ring finger 57 by the hook-and-loop fastener 35 of the band portion 7. .

  The holder 3 to which the blade body 5 is screwed is attached to two fingers of the index finger 53 and the middle finger 55, or to the four fingers of the index finger 53, the middle finger 55, the ring finger 57, and the little finger 59 (not shown). It can also be fixed by the hook-and-loop fastener 35.

  With the picker 1 fixed to the proximal phalanx of the right hand (FIGS. 3 and 4A), for example, eggplant 73 can be grasped (FIG. 4B). In this state, the three fingers of the index finger 53, the middle finger 55, and the ring finger 57 are interlocked so that the blade body portion 5 is pressed against the portion of the fruit handle 71 and tilted inward, or the hand 51 is pulled forward. Thus, the harvesting operation can be performed in a state where the fruits such as eggplant (vegetables) 73 are grasped with little effort (FIG. 4B).

  Since the plucking device 1 according to the first embodiment is firmly fixed and interlocked with three fingers, the blade portion 5 does not move with a strong force. Therefore, sufficient pressurizing force and cutting force can be obtained, and the harvesting operation for vegetables and fruits can be performed with only the right hand or the left hand.

  Note that FIG. 4 shows an example of a method of using with bare hands so that the positional relationship between the fingers and nails of the right hand becomes clearer. However, in order to protect the thumb of the right hand, the eggplant (vegetables) is attached with the picker 1 fixed to the three fingers of the index finger 53, the middle finger 55 and the ring finger 57 in a state in which leather gloves for work are fitted. For safety reasons, it is preferable to perform a harvesting operation such as 63.

In addition, in FIG. 3, the hook-and-loop fastener 35 and the fastener 31 are gripped together to make them easier to grip, but it goes without saying that they can be placed on the back side of the hand (FIG. 6). ). By arranging the hook-and-loop fastener 35 and the fastener 31 on the back side of the hand (FIG. 6), it is possible to make it difficult to damage vegetables and the like during the harvesting operation.
<Example 2>
