  The present invention will be described in detail based on the embodiment shown in FIGS.

  As shown in the block diagram of the first embodiment in FIG. 1, the chopstick assisting tool is constructed by assembling parts of a first chopstick 11a, a second chopstick 11b, a connecting member 12, a holder 13, and an elastic member 14. As shown in the exploded view of FIG. 2, each part can be disassembled.

  3A is a front view of the connecting member 12, and FIG. 3B is a cross-sectional view taken along line XX of FIG. 3A. The connecting member 12 made of a synthetic resin material is provided with two spaces A and B sandwiched between two plate-like members 12a and 12b by joining two substantially disk-like plate-like members 12a and 12b with partition walls 12c. It has been.

  The partition wall 12c is offset from the space A side without passing through the center of the connecting member 12. The side wall 12d is provided outside the space A, and the space A is inserted into the first chopstick having a substantially rectangular tube cross section. The chopsticks 11a having a quadrangular cross section can be inserted. The side wall 12d is provided with a slit 12f so that the width of the side wall 12d increases in accordance with the thickness of the chopsticks 11a inserted into the first chopstick insertion portion 12e. On the other hand, a pair of shaft portions 12g and 12h are provided to face each other at an eccentric position on the upper side sufficiently away from the space A inside the plate-like members 12a and 12b in the space B.

  4A is a plan view of the holder 13, and FIG. 4B is a front view. The holder 13 made of a synthetic resin material is composed of a second chopstick insertion portion 13a and a fulcrum portion 13b, the second chopstick insertion portion 13a is closed to the upper end, and the upper end portion of the chopstick 11b is composed of an insertable rectangular tube. Similar to the first chopstick insertion portion 12e, a slit 13c whose width is expanded corresponding to the thickness of the chopstick 11b is provided on the outer surface. The outer diameter of the second chopstick insertion portion 13a is substantially equal to the outer diameter of the connecting member 12 in the thickness direction, and an abutting portion 13d along the outer shape of the connecting member 12 is provided at the boundary with the fulcrum portion 13b. The second chopstick insertion portion 13a is prevented from rotating more than necessary.

  Further, the fulcrum part 13b that enters the space B of the connecting member 12 is formed along the inserted chopsticks 11b, and the both sides of the fulcrum part 13b are engaged with the shaft parts 12g and 12h provided on the connecting member 12. And receiving parts 13e and 13f for connecting pivot point part 13b so that rotation is possible are formed. And the rotation center by the receiving parts 13e and 13f becomes the vicinity of the rear-end part of the chopsticks 11b similarly to the correct usage of chopsticks.

  5A is a plan view of the elastic member 14, and FIG. 5B is a front view. The elastic member 14 is made of an elastic synthetic rubber or synthetic resin material for separating the two chopsticks 11a and 11b from each other, and has an insertion hole 14a for removably inserting it into an intermediate portion of the chopstick 11a. In addition, an elastic portion 14b having a semicircular arc shape is formed inside the insertion hole 14a, and a finger hooking portion 14c for a user to attach a ring finger is formed integrally with the insertion hole 14a. Further, an abutting portion 14d is formed at the upper end of the insertion hole 14a along the outer diameter of the connecting member 12 so as to come into contact with the connecting member 12 when the elastic member 14 is moved to the connecting member 12 side. .

  Then, in the assembled state shown in FIG. 1, the chopsticks 11 a from above in the first chopstick insertion portion 12 e of the connecting member 12 in a state where the fulcrum portion 13 b of the holder 13 is rotatably attached to the connecting member 12. With the tip of the chopsticks as the tip. At this time, since the chopsticks 11a are gradually thickened from the tip of the chopsticks, the slit 12f of the side wall 12d is expanded as the chopsticks are inserted, and the chopsticks 11a are fixed at a predetermined position by the elastic force. Next, when the rear end portion of the chopsticks 11b is inserted to the back of the second chopstick insertion portion 13a of the holder 13, the chopsticks 11b are fixed by the resilient force of the slit 13c.

  Subsequently, the elastic member 14 is inserted from the tip of the chopsticks 11a with the finger hooking portion 14c on the outside, and the semicircular arc-shaped convex portion of the elastic portion 14b is inserted into the insertion hole 14a, and the elastic portion 14b. Is inserted into the space B of the connecting member 12 and attached so that the tip of the elastic portion 14b contacts the inside of the chopsticks 11b. In this case, since the elastic portion 14b is sandwiched between the plate-like members 12a and 12b of the connecting member 12, the tip thereof does not come off from the chopsticks 11b, and always exerts a biasing force on the chopsticks 11b. Further, since the elastic member 14 is made of an elastic body, the finger hook portion 14c is adjusted to an appropriate position according to the size of the user's hand and the like because the elastic member 14 is in close contact with the chopsticks 11a even if the position is slightly shifted. it can.

  In the first step applied to a person who is least skilled in using chopsticks, the chopsticks are used in an assembled state as shown in FIG. When the two chopsticks 11a and 11b are to be closed, the chopstick 11b rotates with respect to the connecting member 12 about the shaft portions 12g and 12h and the receiving portions 13e and 13f. Since this rotation center is decentered toward the first chopstick insertion portion 13a, it operates in a state close to how to use two normal chopsticks.

  Further, since the tip side of the movable chopstick 11b from the second chopstick insertion portion 13a is sandwiched between the plate-like members 12a and 12b and the movement is restricted, the chopstick 11b rotates in parallel with the fixed chopstick 11a. In addition, the chopstick tips of the chopsticks 11a and 11b are not easily displaced, and food can be easily picked.

  The chopsticks 11b is urged by the elastic portion 14b of the elastic member 14 in a direction in which the tips of the two chopsticks 11a and 11b are separated from each other. Therefore, when the chopsticks 11a and 11b are opened, the urging force facilitates this operation, so that the chopsticks 11a and 11b can be opened easily. Then, when closing the two chopsticks 11a and 11b as shown in FIG. 6, the chopsticks 11b may be closed against the urging force generated by crushing the elastic portion 14b of the elastic member 14.

  FIG. 7 is a perspective view in a first step in which the user uses the chopstick assisting tool in the state of FIG. Since this chopsticks auxiliary tool has an elastic member 14 having a finger hook part 14c, if a ring finger is attached to the finger hook part 14c, it is possible to learn how to hold the chopsticks naturally. There is no need to know if it should be supported in position.

  If you need to use chopsticks temporarily, such as when a foreigner eats Japanese food, you can use it in this first step. To learn how to use chopsticks, It is necessary to go through the steps. That is, in the first step, even if the position where the chopsticks 11a and 11b are held and how to move the chopsticks 11a and 11b can be imagined, the chopstick tips of the two chopsticks are used using ordinary chopsticks without chopstick aids. It is difficult to repeat the operation of closing the two together and the operation of opening the two chopsticks.

  Therefore, when the food can be picked with the chopstick tip to some extent in the first step, the elastic member 14 is removed as shown in FIG. 8, and the process proceeds to the second step. In this second step, the chopsticks 11a and 11b are connected by the connecting member 12 and the holder 13, and the operation of closing the chopstick tips together by the two plate-like members 12a and 12b of the connecting member 12 is assisted. However, since there is no biasing force of the elastic member 14, the two chopsticks 11a and 11b must be opened by operating their fingers.

  In this second step, when the user learns to open the two chopsticks 11a and 11b and can pick up food with the tip of the chopsticks to some extent, the connecting member 12 and the holder 13 are further removed from the chopsticks 11a and 11b. Is moved to the third step of only the chopsticks 11a and 11b and used as a normal chopstick.

  Thus, the elastic member 14 of the present embodiment can be detachably attached to the chopsticks 1a. Thereby, according to the proficiency level of how to use chopsticks, the chopstick assisting tool has the configuration shown in the first step shown in FIG. 7, the second step shown in FIG. 8, and the third step including only chopsticks 11a and 11b. Can be changed.

  FIG. 9 is a configuration diagram of the chopstick assisting device of the second embodiment, and the same members as those of the first embodiment are denoted by the same reference numerals. The chopsticks 11a and 11b in the second embodiment are connected to each other at the rear end portion by a connecting member 21 so that the chopstick tip can be opened and closed. The connecting member 21 is made of synthetic resin, and first and second chopstick insertion portions 21a and 21b for inserting rear ends of the chopsticks 11a and 11b are movably connected by a flexible hinge 21c. The first and second chopstick insertion portions 21a and 21b are provided with slits 21d and 21e on the side surfaces in order to elastically hold the chopsticks 11a and 11b.

  The connecting member 21 uses the hinge 21c to connect the rear portions of the chopsticks 11a and 11b, but there is no biasing force for opening the chopsticks 11a and 11b. Therefore, in the chopstick assisting tool of the second embodiment, the elastic member 14 is attached to the chopstick 11a by inserting the same middle portion of the chopstick 11a as in the first embodiment into the insertion hole 14a of the elastic member 14.

  Thus, as in the first embodiment, the chopsticks 11b are urged in the direction of separation by the elastic portion 14b of the elastic member 14, and this urging force facilitates the detachment operation, so that the chopsticks 11a and 11b can be easily opened. Can do.

  Also in the chopstick assisting tool of the second embodiment, it is possible to learn how to use chopsticks by using the same method as in the first embodiment.

  In this case, since the tip of the resilient portion 14b of the elastic member 14 is easily detached from the chopsticks 11b, as in the modification shown in FIG. 10, the tip for engaging the tip of the resilient portion 14b with the chopsticks 11b is used. It is preferable to use a letter-shaped recess 14e.

  In the elastic member 14 described above, there is one insertion hole 14a through which the chopsticks 11a are inserted. However, in the elastic member 14 in the second modification, the chopsticks 11b are attached to the tip of the elastic portion 14b as shown in FIG. An insertion hole 14f for insertion is provided.

  As a result, the chopsticks 11a are inserted into the insertion hole 14a and the chopsticks 11b are inserted into the insertion hole 14f, so that the chopsticks 11a and 11b are securely elastically connected by the elastic member 14, and the chopsticks 11a and 11b are separated from each other. A force is generated, and the elastic portion 14b of the elastic member 14 is not detached from the chopsticks 11a and 11b.

  In the first to third embodiments, the elastic member 14 is provided with the finger hooking portion 14c. However, the finger hooking portion 14c is not necessarily indispensable.
