As described above, in the training chopsticks provided with the first ring that allows the thumb to be inserted into the fixed chopsticks and the second ring and the third ring that allow the index finger and middle finger to be inserted into the swinging chopsticks, In order to make the swinging chopsticks swing easily with the index finger and the middle finger while being fixed to the side, conventionally, a fixed chopstick and a tail end of the swinging chopstick are mutually connected.

However, in the case of a training chopstick that pivots the fixed chopstick and the swing chopstick's tail, the swing fulcrum of the swing chopstick is located behind the MP joint of the index finger (joint on the most proximal side of the finger). In order to swing the swinging chopsticks, the entire index finger must be moved up and down, which is not preferable, unlike the actual correct usage of chopsticks. In order to learn the correct usage method, it is desirable to make the swing chopsticks swing by moving the index finger up and down at the PIP joint (second joint from the fingertip).

By the way, when the swing chopstick is swung by moving the index finger up and down at the PIP joint, the tail end of the swing chopstick swings up and down toward the tail end of the fixed chopstick. Therefore, the tail end of the swinging chopstick rubs along the skin on the side of the proximal phalanx of the index finger (the bone between the PIP joint and the MP joint), thereby preventing the free movement of the index finger and using the correct chopstick. Make it difficult. For this reason, it is desirable to configure so that the tail end of the swinging chopsticks does not rub against the index finger.

In addition, there are various problems to be solved in order to provide excellent training chopsticks.

The present invention provides a training chopstick that solves the above-mentioned problems, and is configured as means for fixing a chopstick placed between a thumb and an index finger when used by a user, and above the fixed chopstick. A swing chopstick that can be swung up and down by an index finger and a middle finger is provided, a first ring that allows a thumb to be inserted into the fixed chopstick is provided, and a second ring and a third that allow the index finger and the middle finger to be inserted into the swing chopstick. In the training chopsticks provided with a ring, the fixed chopsticks have a bracket erected closer to the tail end than the first ring, and a housing is fixed to the tail end of the fixed chopsticks. The portion facing the tip of the thumb inserted through one ring is pivotally connected to the bracket, and the tail end of the swing chopstick is loosely inserted into the housing, and the tail end of the swing chopstick is allowed to swing in the housing. This is in that a window opening is provided.

In a preferred embodiment of the present invention, when the tail end portion of the fixed chopstick is sandwiched between the thumb and the index finger, the housing constitutes a fixing auxiliary means for pressing and fixing the housing to the base portion of the index finger.

The second ring and the third ring are formed by integrally forming a sleeve part fitted to the swing chopsticks, an index finger insertion ring part, and a middle finger insertion ring part from an elastomer material, and elastically holding the sleeve part. It is preferable to detachably attach the swing chopsticks.

At this time, similarly to the first ring, a sleeve portion fitted to the fixed chopsticks and a ring portion for inserting the thumb are integrally formed of an elastomer material, and can be attached to and detached from the fixed chopsticks through elastic holding of the sleeve portion. It is preferable to attach to.

A notch-shaped bearing part is formed in the bracket of the fixed chopsticks, a slit for inserting the bracket into the swinging chopsticks is formed, and a pivot pivotally supported by the bearing part is installed in the slit, The bracket is provided with a plate-like first tongue piece and a second tongue piece sandwiching the bearing portion, and the first tongue piece and the second tongue piece are formed to be offset from each other in the axial direction of the bearing portion, It is preferable that the first tongue piece and the second tongue piece are brought into contact with each of the opposing wall surfaces of the slit in a state where the pivot is pivotally supported by the bearing portion.

According to the first aspect of the present invention, the user places the fixed chopsticks 1 between the thumb S and the index finger F, inserts the thumb S into the first ring portion 3, and the second ring 4 and the third ring. In the state where the index finger F and the middle finger M are inserted into 5, the swing chopsticks 2 can be moved up and down to learn how to use the correct chopsticks.

In particular, according to the present invention, the swing fulcrum of the swing chopsticks 2 constituted by the pivot 10 is located near the tip of the thumb S and faces the PIP joint (second joint from the fingertip) Q of the index finger F. Therefore, the user is trained to swing the swinging chopsticks 2 while moving the index finger F up and down using the PIP joint Q as a fulcrum, so that the user can learn how to use the correct chopsticks.

At this time, the tail end of the swinging chopsticks 2 swings up and down toward the tail end of the fixed chopsticks 1, but the tail end of the swinging chopsticks 2 swings inside the housing 7, and the user's hand. Since no part is rubbed, the free movement of the index finger F is not hindered, and the correct usage of chopsticks can be learned without a sense of incongruity.

According to this invention of Claim 2, there exists an advantage which can fix the fixed chopstick 1 in a stable state. That is, infants who need chopstick use training are not accustomed to moving each finger of their hands independently, and if the index finger F or middle finger M is moved, the thumb S may move simultaneously. The training chopsticks according to the present invention constitute a fixing auxiliary means 29 in which the housing 7 is pressed and fixed to the base of the index finger F when the tail end of the fixed chopstick 1 is sandwiched between the thumb S and the index finger F. Since the fixed chopsticks 1 can be stably fixed to the user's hand, the swinging chopsticks 2 can be easily swung by the vertical movement of the index finger F and middle finger M.

According to the present invention described in claim 3 and claim 4, the thumb S is inserted into the first ring 3, the index finger F and the middle finger M are inserted into the second ring 4 and the third ring 5, thereby assisting the ring. The first step to train by removing the second ring 4 and the third ring 5, the second step to train until the swinging chopsticks 2 can be swung without the ring, and remove all the rings and fix without the ring With the chopsticks 1 fixed, the third step of training the swinging chopsticks 2 so that they can swing without a ring is possible, and training to learn how to use the correct chopsticks can be performed step by step. .

According to the fifth aspect of the present invention, the first tongue piece 17 and the second tongue piece are respectively formed on the opposing wall surfaces of the slit 8 with respect to the configuration of the swing fulcrum of the swing chopsticks 2 formed by the pivot 10. 18 makes it possible to smoothly swing the swinging chopsticks 2 without rattling, and to learn the correct way of moving the index finger F with an appropriate frictional resistance.

According to the training chopsticks having the above configuration, as shown in FIG. 1, the user places the fixed chopstick 1 between the thumb S and the index finger F, inserts the thumb S into the first ring portion 3, and the second ring 4. In the state where the index finger F and the middle finger M are inserted into the third ring 5, the correct usage of the chopsticks can be learned by moving the swinging chopsticks 2 up and down.

Infants who need chopstick use training are not accustomed to moving their fingers independently, and moving the index finger F or middle finger M may cause the thumb S to move simultaneously. According to this, when the tail end portion of the fixed chopstick 1 is sandwiched between the thumb S and the index finger F, the housing 7 constitutes the fixing auxiliary means 29 that is pressed and fixed to the base portion of the index finger F. Therefore, since the fixed chopsticks 1 are well fixed to the user's hand, the fixed chopsticks 1 will not become unstable when the index finger F and the middle finger M are moved up and down to swing the swing chopsticks 2. .

As shown in FIG. 1, the swing fulcrum of the swing chopsticks 2 constituted by the pivot 10 is located in the vicinity of the seat 19 to which the tip of the thumb S is attached, and the PIP joint (second second from the fingertip) of the index finger F. (2 joints) Since it faces Q, the user does not move the index finger F up and down, but swings the swinging chopsticks 2 while moving the tip part of the index finger F up and down with the PIP joint Q as a fulcrum. You can learn how to use chopsticks correctly.

At this time, the tail end of the swinging chopsticks 2 swings up and down toward the tail end of the fixed chopsticks 1, but the tail end of the swinging chopsticks 2 swings inside the housing 7, and the user's hand. Since no part is rubbed, the free movement of the index finger F is not hindered, and the correct usage of chopsticks can be learned without a sense of incongruity.

Further, as described above, the first tongue piece 17 and the second tongue piece 18 are in contact with the opposing wall surfaces of the slit 8, as described above, at the swing fulcrum of the swing chopsticks 2 constituted by the pivot 10. As a result, the swinging chopsticks 2 can be smoothly swung without rattling, and by giving an appropriate frictional resistance, the correct movement method of the index finger F can be learned.

Furthermore, training on how to use the correct chopsticks can be performed step by step through the following three steps. The first step trains the thumb S with the help of the ring by inserting the first ring 3, the index finger F and the middle finger M into the second ring 4 and the third ring 5. In the second step, the second ring 4 and the third ring 5 are removed, and the swinging chopsticks 2 are trained until they can swing without a ring. In the third step, all the rings are removed, and the swing chopsticks 2 are trained to swing without the rings while the fixed chopsticks 1 are fixed without the rings. The third step is with the help of the fixing auxiliary means 29 by the housing 7, but if the third step can be performed without difficulty, normal chopsticks can be used correctly.
