The present invention relates to a structure of chopsticks, and in particular, in a chopstick consisting of a pair of one fixed side chopsticks rod and an operating side chopsticks rod, a ridge that is a flow operation point is provided on the operating side chopstick rods, and is slipped on the fixed side chopstick rods. The installation of the prevention surface allows the user to accurately identify the position where the chopsticks can be related to the structure of the chopsticks configured to make it easy to learn the principles of how to hold and use chopsticks.

The present inventors had the opportunity to attend a restaurant or a banquet hall where a large number of people ate together, and observed the method and use of chopsticks of attendees who attended the meeting. In addition, the user himself confirmed that many people could not even use the chopsticks (4).

Therefore, the present inventors have investigated hundreds of domestic and foreign patents for chopsticks, and found that the auxiliary devices of various shapes are almost used to secure the chopsticks and the stability of the chopsticks. This prior art is not intended to allow the user to learn how to hold the chopsticks correctly and how to use them for proper use of the chopsticks, and to use the normal chopsticks because the auxiliary equipment is installed outside. Rather than learning, in some cases, the wrong way of using chopsticks is a problem for the user.

In addition, since the chopsticks are slipped from the fingers due to the grease from the food at the time of eating and eating, it is necessary to adjust the position of the center point where the chopsticks are consciously or unconsciously picked up whenever the food is picked up.

In addition, in the chopsticks described in Patent Documents 1 to 4 (Japanese Patent Application Laid-Open No. 10-313998, Japanese Patent Application Laid-Open No. 7-1459, Japanese Utility Model Registration No. 3089628, and Japanese Utility Model Registration No. 3021045), irregularities are placed at the position where the finger is supported. It is disclosed that a portion is formed so that the position of holding the chopsticks is involuntarily shifted slightly.

Or, in Patent Document 5 (Japanese Patent Laid-Open No. 5-21772), an annular protrusion is formed at a position where a finger is supported on the side of the chopstick, and when the chopstick is placed above the food, the protrusion becomes a support portion of the chopsticks. The tip is in contact with food and has been improved to improve hygiene.

However, any of the chopsticks disclosed in such a patent document does not have a structure and function that can be applied to practice how to hold the chopsticks correctly and how to use them.

 Knives and forks used by Westerners are a type of tableware that has been miniaturized to fit the dietary culture, but chopsticks were first invented in China and used for more than 3500 years.

In addition, more than 3500 years have passed since the invention of chopsticks, and will be used the same now or later. Nowadays, however, there are fewer occasions for parents to instruct their children in their homes and less opportunities for teachers to learn how to use chopsticks at school.

Chopsticks are traditional Chinese culture, and their use is regarded as a kind of art, while Chinese or Asian people are gradually decreasing their use, while foreigners hope to learn how to use them. However, it is very difficult to learn how to hold the chopsticks in the correct posture and shape due to the above problems, and for example, there are many difficulties in the side of teaching or being taught.

The reason for this is that the upper part of the chopsticks is usually provided with an additional structure with an additional display part, and is generally required in a facility or environment for learning it, but it is limited to a meal time and teaches how to hold the chopsticks in a short time. Is difficult. In addition, it is difficult for the teacher to hold the chopsticks correctly and to make sure the point of use is clearly known. Therefore, the user needs to practice a lot.

Auxiliary devices for various chopsticks for solving such a problem are described in, for example, Patent Documents 6 to 8 (Japanese Patent Publication No. 2003-275085, Japanese Patent Publication No. 2001-269257, and Taiwan Utility Model Registration No. 78343). Disclosed in each of the patents shown. However, such an auxiliary device of chopsticks loses the shape of the chopsticks body because it connects a pair of chopsticks rods to each other like a forceps used to pick up tweezers or grilled meat.

Alternatively, there is also a chopstick rod using an auxiliary device attached to itself, and a person who wants to learn how to hold a chopstick of a type in which the auxiliary device is attached to the outside attaches and detaches the auxiliary device to the chopstick rod during use. , The attachment work is cumbersome.

Therefore, the auxiliary device attached to the outside of the connection type is additionally installed on the main body of the chopsticks, so that the original shape of the chopsticks is damaged, so there is a problem that the conventional chopsticks are lost as an inherent artistic feature.

Therefore, the present inventor wants to be able to easily grasp the chopsticks and the method of using the same, not by the above-described auxiliary apparatus, and the chopsticks inherent in the form of the chopsticks are not damaged.

The object of the present invention devised to solve the conventional problems as described above is based on the ergonomic analysis of the finger in the human hand, the fixed side chopsticks rods in a pair of chopsticks, based on the results of the movement and seated, the other one The chopsticks rod on the operation side is designed to be able to pick up foods, so that it can be picked up by using the thumb to move to the center point corresponding to the position where the food can be picked up by chopsticks. It is aimed at providing chopsticks to be able to get used to right posture.

In addition, the present invention allows the user, if you are a beginner, to accurately grasp the position of holding the chopsticks, to facilitate its operation and use principle so that anyone can get used to it quickly, and tongs (or tweezers) and Similarly, an object of the present invention is to provide a chopstick which does not have an incorrect use habit such as a method of using chopsticks by a beginner chopstick.

In addition, the present inventors are convinced that by providing the chopsticks as described above, the present invention can contribute to society in a different direction from sophisticated and expensive chopsticks, and at the same time, it will be an opportunity for social joint research on an excellent chopstick culture.

In the following description, the names and definitions of the parts of the fingers described in the specification and the claims are described to make the description easier and to facilitate the accurate understanding. The parenthesis behind each name is now the title of an academic award (anatomy, etc.).

[1] With regard to the nodes of the fingers, the fingers other than the thumb (2) shall be [first section (tip)], [second section (middle section)], and [third section (in the order starting from the tip side). Stun)], and in the joint, the joint between the first node and the second node is referred to as the [joint between the first joint (distal joint and DIP joint) and the joint between the second and third nodes to the second joint (proximal). Joint.PIP joint)], and the joint of the hand that leads to the third node is referred to as the third joint (carpal joint. MP joint)].

[2] On the other hand, in the node of the thumb 2, it is called <the 1st node (end)> and <the 2nd node (the stun)> in order from the front end side, In the [joint], the said 1st node and the 1st Between two nodes, the joint is referred to as [first joint (IP joint)] and the joint corresponding to the root leading to the hand at the second node is referred to as [second joint (root joint of hand (carpal joint. MP joint)].

And practice chopsticks according to the present invention for achieving the above object;

In the chopsticks which consists of a chopstick stick which pairs the operation side chopstick stick 10 and the fixed side chopstick stick 20;

At least in the use of the operating side chopsticks rods 10, a ridge is formed in a portion gripped by the thumb 2 and the perception 4, and is formed in a protrusion having an annular rounded vertex at the top of the ridge. A configuration in which the top portion contacts at least a small area with a wrinkled face of the thumb 2 so that the user can recognize the ridge;

In use, the mask of the first node of the thumb 2 and the proper portion of the first joint to the second node of the cognitive 4 are in close contact with the ridge, and the ridge is located at the center of the flow operation of the chopstick rod on the operation side. Close contact, and on the one hand, the tip side is supported by the ridge of the operation side chopstick rod at the first node of the cognitive rod and the middle rod 5 so that the recognition and the middle finger 5 are operated by bending and releasing the handle. Side chopsticks rod is characterized in that the configuration to be flow-operated at the ridge.

The ridge may be formed as a semi-cylindrical or triangular protrusion as an annular band on the top of the chopstick rod.

In this case, the ridge formed as the semi-cylindrical or triangular protrusion is formed with an uneven portion around the position for forming the ridge on a part of two opposite sides of the chopstick rod, or the semi-cylindrical or triangular It is preferable that the ridge formed from the projections of the protrusions is formed to protrude by a predetermined length from a part of two opposite sides of the chopstick rod.

On the other hand, the ridge can be formed as an annular protrusion of a cross-sectional arch shape surrounding the outer circumference of the chopstick rod.

In this case, the ridge formed as the annular protrusion has irregularities on both sides of the position where the ridge is formed at a portion of the outer circumference of the chopstick rod, or a portion of the outer circumferential surface of the chopstick rod is outward of the outer circumferential surface. As it protrudes, it is possible to form.

The length of the ridge portion, the axial length of the chopstick rod that starts to protrude from the outer peripheral surface of the chopstick rod can be 1.0 to 15mm. The length in the axial direction is less than 1.0 mm, so that the smallest finger cannot be identified. On the contrary, when it exceeds 15.0 mm, it becomes difficult to be able to specify the position in the axial direction from the largest finger.

In addition, it is preferable that the height from the position where the ridge starts to rise vertically is 0.5-5 mm.

If the height is less than 0.5mm, the smallest finger is not identified. On the contrary, when the height is greater than 5.0mm, it protrudes greatly from the outside, which is not good for appearance, and the fixing and movement of the chopsticks in which the fingers are closely attached are unstable. do.

Alternatively, when the ridge is a triangular protrusion, it is preferable that the start portion at which the protrusion starts to protrude is 1.0 mm or more in length in the width direction of the chopstick rod and less than or equal to the size of the chopstick rod. When the length of the width direction of the chopstick rod having the projections is less than 1.0 mm, the smallest finger is not identified, and it is impossible to become larger than the size of the chopstick rod.

Preferably, the ridge is formed integrally with the chopstick rod and is formed as a separate member from the chopstick rod and attached to the chopstick rod.

In another preferred embodiment, the fixed side chopstick rod is also provided with a ridge having the same shape as the raised portion of the operating side chopstick rod at the same position (ie, a symmetrical position) with the operating side chopstick rod.

It is recommended to form a non-slip surface to prevent the support positioning and slipping in the support portion in contact with the ring finger (7) in the fixed side chopstick rod. In addition, a non-slip surface that is the same as the non-slip surface on the fixed side chopstick rod on the operation side chopsticks is installed at the same position as the fixed side chopsticks, and the anti-slip surface is an annular irregularity surrounding the outer peripheral surface of the chopstick rod It is preferable to become a part).

And a positioning member for fixing the position of the thumb on the tip side of the chopstick of the ridge on the operation side chopstick rod for beginners such as infants, and the positioning member includes an inclined surface downward from the ridge. It is preferable that the first section of the thumb is easily configured to be accurately set at a predetermined position of the chopsticks because the one-sided mask is brought close to the ridge.

In another embodiment, the fastening portion for applying the force to the chopstick rod while the position of the formation of the non-slip surface of the fixed side chopstick rod, the thumb and perception extending from the user's hand to narrow the fingerprint portion therebetween Each of the positioning members is provided, and on the positioning members provided at the non-slip surfaces, one support protrusion is formed to protrude so as to intersect a predetermined interval in order to bring the first node of the ring finger 7 into close contact. .

During the use of chopsticks, the thumb should not be spaced apart from the rubber and the middle finger (5) mounted over the palm and back of the hand from the point where the thumb starts to extend from the hand so that the gap between the finger is not too wide. In order to bind the perception and middle finger (5), it is preferable to have a rubber mold and a ring rubber for tying the ring finger (7) and the little finger so as not to be spaced apart from the ring finger (7).

First, the correct posture to hold chopsticks and the posture of chopsticks, which are generally known, are divided into three sections.

(1) In a pair of chopstick sticks, the operation side chopsticks rod 10 is the same as the posture of holding a chalk, and one operation side chopsticks rod 10 is 3 of a thumb (2), a recognition (4), and a middle finger (5). Grip the dog's fingers, then slightly spread the perception (4) and middle finger (5), while at the same time the thumb (2) holds the chopstick rod at the position of approximately the first joint of the perception (4) Since the two fingers of the perception (4) and the middle finger (5) are bent and removed at the same time, the operation side chopstick rod (10) is in close contact with the three fingers and flows around the pressed portion to operate. A) to (C) and (A) to (D) of FIG. 4].

(2) For the fixed side chopstick rods 20 of a pair of chopstick rods, the upper portion of the thumb (2) and the cognitive (4) extends from the hand (part corresponding to the root of the thumb and cognitive). It is located between the fingerprint portion and the ring finger 7 between (2) and recognition (4). (See Figs. 4A to 4D.)

As described above, in the operations of (1) and (2), which direction is the first, which direction is the same, and the same is the same in both directions.

(3) By the above operation, the operation side chopstick rod 10 and the fixed side chopstick rod 20 as shown in Figs. 4A to 4D are held by hand, and the thumb 2 is always In the unfolded state is sandwiched between the first joint and the second node of the perception (4). When using chopsticks, the tips of the four fingers other than the thumb (2) remain roughly bent, and when picking up food, the fingers (4) and middle finger (5) are bent and released at the same time. With the portion of the side of the chopsticks upwardly contacted by the thumb 2 as the flow center point, the operation side chopsticks rod 10 is moved as if it is flowed by the lever so that food can be picked up from the tip of the chopsticks.

Since the actual chopsticks that are actually used are not engraved, it is very difficult for a user practicing how to hold a chopstick, that is, a beginner, can accurately understand and acquire the position and operation principle of holding a chopstick. Particularly, in the operation method of flowing the portion pressed by the thumb 2 of the operation side chopstick rod 10 to the center point during operation, the fixed side chopstick rod 20 needs to be placed on the finger without moving. By doing so, it is very difficult to make a correct posture on how to hold and use chopsticks.

Therefore, description will be given with reference to FIGS. 1 and 2.

The first chopstick for practicing according to the present invention is composed of an operation side chopsticks rod 10 and a fixed side chopsticks rod 20, and at least in the upward portion of the operation side chopsticks rod 10, the thumb 2 and the recognition The ridge portion 11a (in the case of the embodiment of Fig. 2, 11b) is formed at the portion sandwiched between (4), and the ridge portions 11a and 11b have a projection having an annular band at the top portion. It is formed so that the user can recognize the ridges 11a and 11b by at least contacting the back surface of the thumb 2 in a small area.

In use, the user places the ridges 11a and 11b on the back face (fingerprinted side 301) with the first node 30 of the thumb 2, as shown in Figs. 3A to 3C. As shown, the mask 301 of the thumb 2 positions the ridges 11a and 11b at the proper site of the mask from the first joint of the perception 4 to the second node 402. The bases 11a and 11b are made to be the flow manipulation center points of the operation side chopstick rod 10, and the user manipulates the first node 401 of the perception 4 and the first node 501 of the middle finger 5. The operation side chopsticks rod 10 is operated by inserting the tip side by the ridges 11a and 11b of the side chopstick rods 10 and bending while removing the perception 4 and the middle finger 5. The flow is manipulated using the ridge 11 as the center point.

The basic shape of the chopsticks includes the shape of the tip as it is, for example, as shown in Figure 1, in the vertical cross-section of the chopstick rods 10, 20 flat flat, as shown in Figure 2 the vertical of the chopstick rods The cross section is in a substantially forward direction or as shown in FIG. 7, wherein the vertical section of the chopstick rod is circular.

The shape of the ridge 11a (11b in the embodiment of FIG. 2) formed on the operation side chopstick rod 10 of the chopstick 1 is designed and modified to suit the basic shape of the chopstick rod of the chopstick 1, and the operation When the side chopstick rod 10 has a flat vertical cross section, as shown in the BB cross-sectional view of FIG. 1, the ridge 11a formed on the side of the chopstick rod has a semi-cylindrical protrusion as the end of the chopstick rod. Is formed.

Alternatively, when the vertical section of the operation side chopsticks rod 10 becomes substantially square as shown in FIG. 2, the ridge 11b surrounds the outer circumference of the chopstick rod as shown in FF section of FIG. 2. The cross section is formed of an arcuate annular protrusion 11.

In addition, as shown in the JJ cross-sectional view of FIG. 5, a part is formed as an uneven portion 103 on two opposite sides of the operation side chopstick rod 10, and a triangular ridge 11c is formed in the uneven portion 103. ).

Alternatively, as shown in Fig. 6, the vertical cross section is provided with an uneven portion 104 on the outer circumference portion of the substantially square operation side chopstick rod 10, and a raised portion formed as an annular protrusion in the center of the uneven portion. (11d) is formed.

In another embodiment, when the vertical cross section is a circular operation side chopstick rod 10, an annular ridge 11e protruding higher than the outer circumferential surface of the chopstick rod as shown in FIG. It is also possible to configure. The ridge portion 11e forms a ridge portion 11e by attaching the ridge portion 11e to the outer circumference of the chopstick rod by manufacturing a processing molding integrated with the operation side chopstick rod 10 or by making a separate member. It is also possible.

The method of holding the chopsticks is as shown in (A) to (C) of Figure 3, the user can easily identify the position where the chopsticks can be removed using the position display function of the ridges (11, 11a ~ 11e) And the ridge 11 for the purpose of determining the position of the flow center point of the operation side chopstick rod 10 to confirm or to make the flow center point of the operation side chopstick rod 10 in a shape suitable for the human body. Equipped.

Next, as shown in FIGS. 4A and 4B, the upper part of the fixed side chopstick rod 20 is seated on the fingerprint part 6 corresponding to the root of the thumb 2 and the cognition 4. And is fixed between the second node 201 of the thumb 2 and the first node 701 of the ring finger 7 so that the fixed side chopstick rod 20 corresponds to the root of the thumb 2 and the cognition 4. It is fixed in contact with the fingerprint portion 6, the second node 202 of the thumb 2, and the first node 701 of the ring finger 7. Therefore, according to the above-described operation of claim 1 to claim 3, the manner of holding the chopsticks in the correct posture can be easily learned, the difficulty of the practice can be solved.

Next, the operation method of a chopstick is demonstrated with reference to FIG.4 (B)-(D).

The user makes the back surface 301 of the first node 3 of the thumb 2 close to the ridge 11 of the chopstick rod 10 on the operation side, and at the same time, the first node 3 of the thumb 2. The ridge 11 is brought into close contact with the ridge 11 in an arbitrary region extending from the first joint of the mask 301 and the perception 4 to the second node 402. At the same time as the flow center of (10), the chopsticks are inserted into the first node 401 of the cognitive 4 and the first node 501 of the middle finger 5, and the second cognitive 4 is held. As the second joint of the joint and middle finger 5 is bent and pulled out, the operation side chopstick rod 10 flows around the ridge 11, as shown in FIG. 4B. It pushes the side of the mask on which the fingerprint portion of the perception (4) is formed in a downward direction as shown in FIG. 4 (B), so that food can be picked up and the chopsticks are made by returning the middle finger (5) upward. Food may be dropped by spreading between the rods 10 and 20.

In order to pick up food, the operation side chopsticks rod 10 is flow-operated and the fixed side chopsticks rod 20 is fixed at a certain position without movement. It is picked up with chopsticks regardless of the size of the object, such as when picking up one peanut as shown in FIG. 4 (C) or when picking up one egg as shown in FIG. 4D. Can be.

As shown in FIG. 4 (C) and (D) as described above, the fixed side chopstick rod 20 is fixed without movement, and the recognition 4 and middle finger 5 are opposite to the back of the hand 8. At the same time bent at the same time to the chopsticks rod 10 on the operating side to flow around the ridge. As shown in FIG. 4C, the angle between the back of the hand 8 and the perception 4 is not larger than the angle of bending the finger a1 and is smaller than the angle a2 of returning the finger. It was able to pick up small foods.

The ridge 11 is not limited to the case where it is installed on the operation side chopstick rod 10, and the ridge 11 of the operation side chopstick rod 10 also on the fixed side chopstick rod 20 omitted from the drawing. It is also possible to have a ridge of the same shape installed at the same position corresponding to. In the chopsticks according to the present invention, the shape of the operation side chopsticks rod 10 and the fixed side chopsticks rods 20 are formed to be symmetrical with each other, thereby further improving the decorative effect of the chopsticks, and selecting the appearance configuration of the chopsticks. It makes it possible to widen the range.

1, 2, 8 to 10, in the chopsticks according to the present invention, the portion of the chopstick rod 10 and the fixed side of the chopstick rod 20 in contact with the user's finger is a non-slip surface ( 21) is preferred. For example, the non-slip surface 21 is formed in the part which contacts the 1st node 701 of the ring finger 7 which contacts the fixed side chopstick rod 20. As shown in FIG. The non-slip surface 21 has a function of displaying the position of holding the chopsticks and a function of preventing slipping, and the user can easily identify the position of placing the fixed side chopstick rod 20 on the ring finger (7). At the same time, the anti-slip effect can increase the holding force on the finger. Therefore, it is possible to improve the positioning effect of the fixed side chopsticks rods 20 and to prevent the fixed side chopsticks rods 20 from moving out of the corresponding position regardless of the user's will.

It is preferable that the non-slip surface (not shown) of the operation side chopstick rod 10 and the non-slip surface 21 of the fixed side chopstick rod 20 are installed at positions symmetrical with each other. The shape and density of the non-slip surface 21 is not limited. To illustrate this example, the MM cross-sectional view of FIG. 8, the NN cross-sectional view of FIG. 9, and the concave-convex portions shown in FIG. 10 and the PP cross-sectional view thereof are illustrated. Fixed side chopsticks rod 20 directly forms a plurality of sets at a predetermined position on the side, thereby increasing the range of the identification effect, the non-slip effect, the decorative effect and the selectability of the chopsticks for the position where the finger is raised have.

 Next, an embodiment as shown in FIGS. 11 and 12 will be described.

The embodiment relates to a chopstick that can be learned how to grasp for beginners who have not used chopsticks, according to the present invention, the chopsticks according to the present invention, the chopsticks 10 and the fixed side chopsticks rods 20 Positioning members 12, 22, and 23 are installed to determine the raised position, and at the same time, the rubber mold 30 is applied. The positioning members 12, 22, and 23 are provided at the front end of the chopsticks of the ridge 11, have a downward slope on the ridge 11, and the thumb 2 of the first node 3 Since the masking surface 201 is brought into precise contact with the ridge 11, the side surface corresponding to the opposite side of the perception 4 of the first node 3 of the thumb 2 is shown in FIGS. 15C and 15D.
