:的位置作為旋轉轴’可使上筷子部㈣ t運動，從而使上‘許部件相對於下筷子部件打開= δ攏’而梅指相對下, 筷子部件是不動的。 過往已經有—些辅助型筷子。這些筷子上設有拇指固定裳 置。例如’美國專利则77464披露了 _種學制棋子广 中國實用新型專利CN87205972U也公開了一種相類似的持 怏矯正③H許的原理是在兩歧子的表砂置—些吻 ^手指形狀的凹陷區域’用於引導持㈣手指。其不足之處 疋’由於⑨些凹陷位於筷子本身，只能糾導與筷子本身接 _手指部分’但不能引導無付直接_的手指部分。 最初學習持筷時會遇到一些困難，例如，初學者不容易掌 握拇指與食指第三節的相對位置1 _，如絲指向繞側 過分偏側，或者向尺觸分偏側，都會引致持料正確的問 題。 雖然梅指橈側和梅指尺側在外觀上大致上是相對稱的。但 是’由於人的手的形狀並不對稱，拇指橈側面向手掌前面和 其他手指，而拇指尺側面向手掌的背面而不面向任何手指， 所以在持«，撼偏向於橈辦（即，姑過於靠近食指 TF1005038 4 201230990 第一節）所引起的問題與拇指偏向於尺側時（即，拇指過於靠 近食指第三節）所引起的問題是完全不同的。當拇指向橈側 過分傾側，就會令作為上筷子部件支點的拇指第一節過分地 接近食指第一節和中指第一節’讓拇指第一節防礙了該兩個 指節控制上筷子部件開合的動作’減低了筷子合攏的力量。 •另外，當拇指向尺側過分傾側，就會令拇指與食指第三節過 分接近而形成如第三圖所示的持筷扭曲的情形。由於持筷扭 ♦曲會令學習者完全無法正確㈣，所以這個問題比拇指向繞 侧過分傾侧所引發的問題要嚴重得多。 正確持怏時（見第-圖;），梅指按著下换子部件的前面，食 指第三節底部和以下的部位3 8按住下換子部件的背面，姆 指和食指第三節在下模子部件的前後兩面相對。然而，它們 與下快子藉夾持端28的距離並不相同，拇指比食指第三 指節更為接近下棋子部件的失持端28。初學者不容易掌握 ❿這個分別’初學者容易誤以為它們是直接相對的。這個學解 會令拇指向下奸部件的尾端29侧，也令食指第三節向 下^部件的㈣端28傾側，錯誤地使拇指過於接近食指 • ^一即（見第二圖）’令整個持棋姿勢完全變形而不能正確持

一旦安裝了以個引導件，下筷子部件就有了兩個與拇指接 觸的位置，就是适個引導件與拇指尺側接觸的位置，和下筷 子部件前面與拇指第二節指腹接觸的位置。這兩個位置互相 分隔開，形成一直線，這直線與下筷子部件大致互相垂直， 以致能夠引導著拇指保持如第一圖所示大致垂直的正確姿 勢。而且，該引導件通過連接件與下筷子部件隔開一定距 離，比直接設在下筷子部件本體上更能有效地引導拇指的定 位。如第五圖所示，一隻手通過本發明實施例的人體工學裝 置可以以正確的姿勢握持一對筷子。 第六至第九圖所示為上述實施例的人體工學裝置的多種 變型，其中，相同的部件以相同的元件符號標示，不同的部 件在各種變蜇中以順序遞增的角碼表示。 在第六圖中，連接件13丨2的長度較上述實施例中的連接 件131!長，以致於在使用筷子時，拇指引導件1332可達至

作為選擇，還可將拇指引導件、連接件、和食指引導件組 Φ 合為一體，從而形成一種可同時引導拇指和食指的人體工學 裝置，能夠令拇指和食指保持正確的相對位置，以防止如第 三圖所示的持筷扭曲的問題。例如，第二十八至三十圖所示 為本發明合成一體的人體工學裝置的實施例的前面、底面和 背面幾個視圖。第二十八圖示出人體工學裝置的正面圖，人 體工學裝置由一固定在下筷子部件20上的引導件10310構

圖。從第三十圖可見，該人體工學裝置的背面具有與食指第 三指腹及其以下部分接觸且形狀配合的接觸面。 TF1005038 19 201230990 作為選擇，可在上筷子部件1 〇和下筷子部件2〇之間設置 活動連接裝置，用以限定兩筷子部件之間的距離。第三十一 至二十二圖為第二十八圖至第三十圖中所示的人體工學裝 置的一個變型，其中主要分別在於兩支筷子之間設有一活動 連接裝置連接。 參見第三十四圖，活動連接裝置包括一連接桿93和與該 連接桿協同作用的軸桿91。連接桿的一端固定在下筷子部 件的上面22，另一端為自由端，該自由端上設置開口向上 的截面呈C形的卡接口。軸桿91設置在上筷子部件内形成 的接納槽90中，該接納槽設計成足以容納下筷子部件的c 形自由端並允許該自由端在其内適當活動。接納槽90中的 軸桿91用於與連接桿％的卡接口接合，從而使上筷子部件 可以相對下筷子部件轴轉，以使•筷子對的夹持端打開或閉 合。 C形自由端的中心孔的尺寸也可以設置成允許該自由端 相對於軸桿91稍微偏轉，是因為C形卡接口的内徑比所述 軸才干的直徑大，但該自由端不會脫離軸桿，參見第三十五' 圖。k可以訓練學習者單靠手部肌肉協調防止上滨子部件偏 側。 作為選擇，上述的活動連接件可應用於上述任—實施例的 棋子。例如，在同時裝有第十三圖中的拇指引導件和第二十

Description of the invention: [Technical field to which the invention pertains]: The invention relates to a secret, in particular, to a chopstick for learning an ergonomic device that correctly holds a posture. [Prior Art] The people of the country have been eating food for three thousand years. The chopsticks used in the first section are paired with a columnar upper chopstick member 1Q and a lower mold member 2^-. The upper end 18 of the upper chopsticks part and the lower part of the chopsticks part are used to hold the food, and the upper and lower stalks are used for the scaly food material 1 and the other is called the end end. The upper part of the upper part and the lower chopsticks are called the front m; the upper part of the n22 Λ is the upper part, and the middle part of the third part of the middle finger and the index finger is called the back side: the first picture: the downward side ( Not shown) is called the bottom surface. However, chopsticks are round, and so on. In the -polygon, circle, and expansion in the nucleus, the number of fingers refers to the first lang of the fingertips, which in turn refers to other knuckles as the second section, the third section (the thumb does not have the third Section). In addition, the thumb is close to the side of the forearm's tibia - the side 33, the thumb is close to the forearm, and the thumb is close to the hand in the direction of the moon. The side is called the thumb ulnar side 34. The correct posture for the supply is shown by the first figure. When holding the town, the ring finger 36 and the bottom of the index finger at the bottom and below the % position contact the north side of the mold part 'thumb of the second knuckle 32 and hold the front of the lower chopsticks part, through the three = TF1005038 3 201230990 == _ pieces, and the lower mold parts and hands two:. Contrary to this, the upper chopsticks h. It is possible to move the first W and the middle material - the knuckle μ on the third section of the chopsticks section and the third section of the index finger are also clamped on the _ piece, the position of the thumb and the medicine ^: as the axis of rotation 'can make the upper chopsticks (4) t movement, so that the upper part of the part is opened relative to the lower chopsticks part = δ ' and the plume is relatively lower, the chopstick parts are not moving. There have been some auxiliary chopsticks in the past. These chopsticks are provided with a thumb-fixed skirt. For example, 'US Patent No. 77464 discloses that _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 'Used to guide the holding (four) fingers. The shortcomings 疋' Because the 9 depressions are located in the chopsticks themselves, they can only be stalked with the chopsticks themselves _ finger parts but can not guide the finger parts without paying direct _. When you first learn to hold chopsticks, you will encounter some difficulties. For example, it is not easy for beginners to grasp the relative position of the third section of the thumb and forefinger 1 _. If the silk is pointing too far to the side, or to the side of the ruler, it will lead to The correct question. Although the plume side and the plume side are roughly symmetrical in appearance. But 'because the shape of the human hand is asymmetrical, the thumb squats to the front of the palm and the other fingers, while the thumb sill faces the back of the palm without facing any fingers, so it is biased to do so (ie, The problem caused by the near index finger TF1005038 4 201230990 section 1 is completely different from the problem caused by the thumb being biased towards the ulnar side (ie, the thumb is too close to the third section of the index finger). When the thumb is tilted too far to the temporal side, the first section of the thumb as the fulcrum of the upper chopsticks component is excessively close to the first section of the index finger and the first section of the middle finger. 'The first section of the thumb prevents the two knuckles from controlling the upper chopsticks component. The action of opening and closing 'reduces the power of chopsticks to close. • In addition, when the thumb is excessively tilted to the ulnar side, the thumb is excessively close to the third section of the index finger to form a twisted chopstick as shown in the third figure. Since the twisting of the chopsticks will make the learner completely incapable of correcting (4), this problem is much more serious than the problem caused by the excessive tilting of the thumb to the side. When the squat is correct (see figure - figure;), the plum finger presses the front of the sub-assembly, the bottom of the third section of the index finger and the following parts. 3 8 Press and hold the back of the sub-assembly, the thumb and index finger third section Opposite the front and rear sides of the lower mold part. However, they are not the same distance as the lower fast by the grip end 28, and the thumb is closer to the lost end 28 of the lower pawn component than the third phalanx of the index finger. It is not easy for beginners to master ❿ this distinction. Beginners tend to misunderstand that they are directly relative. This solution will cause the thumb to smear the end 29 side of the component, and also make the third section of the index finger down to the (four) end 28 of the component, erroneously making the thumb too close to the index finger. ^ One (see Figure 2) The entire chess posture is completely deformed and it is impossible to correctly hold the molds on the market with tools that assist the chess. For example, Japanese Patent Laid-Open Publication No. 2005-Π7(8) discloses a supplementary tool for learning a chess piece. The auxiliary tool is provided with a U-shaped bracket fitted near the root of the index finger. It is not TF1005038 201230990 Where is the 曰, upper, C bracket installed in the third section of the adapter with the elastic mechanism and the chess piece 摇 shaking with the opening and closing of the scorpion, can not keep the index finger to guide the bottom of the index finger, but the material Guide the thumb to the correct side = fast child only to pay for the next part. There is an accurate direction and position to press the other 'one silver ancient coffee ± chasing (10) some of the learning tools attached to the movable connection, the quick sub-material and the lower part, such as the above-mentioned day-side. These activity connection devices can only connect to this activity, but they also rely on the beginners. It is not possible to train the coordination of each muscle of the hand. [Inventive content] The object of the present invention is to provide a corrective posture for self-contained materials, and the other object of the present invention is to provide a The ergonomic device (4) slaves learn from beginners with the creek learners to maintain the correct holding gaze posture as the first figure and the ^ or / and the index finger third knuckle 'training in order to train the hand muscles (four). It is a further object of the present invention to provide a correct opening and closing of the present invention. According to a first aspect of the present invention, there is an active connecting device. a guide I for guiding the finger position at least - a guide member including a thumb on the chopstick member has at least a contact surface for contacting the TF _ 铡 铡; and 201230990 I The body fast member is provided with a guide for guiding the index finger. The guide for guiding the index finger has a portion adjacent to the index finger of the third segment of the index finger and/or the face of the finger. Contact surface for contact. The relative positions of the thumb and the lower chopsticks are substantially straight as shown in the figure-- however, the learner's report tends to tilt the thumb excessively toward the ruler. The thumb flutter has only one position to lie down on the chopsticks part, which is to destroy the second quarter of the fingertips. φ contact positions are not easy to make the thumb vertical, and the learner can easily tilt the thumb to the ulnar side with a few Xe contact positions, causing the chopsticks to be twisted as shown in the third figure. That is why we have designed a guide for the ulnar side of the thumb to add a position where the thumb is in contact with the lower silver sub-assembly. This guide member is spaced apart from the lower mold member and is fixed to the front of the lower mold member by a connector. Wherein, the guiding member may be spatially located between the upper chopstick portion and the returned pawn member; or may be located on the dry surface of the upper mold member to guide the first section of the thumb. In the variant, the first end of the guide has a portion extending from the body toward the lower chopstick member, the extension reaching at least the front of the lower chopstick portion and being connected to the connector One to increase the range of contact. . This bow guide has only one side and is difficult to hold stable, making it difficult for beginners to grasp. The user must use the second section of the thumb to press the i-face of the lower chopstick part correctly to get the stability. However, this guide is not completely useless TF1005038 7 201230990 because it still has the effect of supporting chopsticks', but it is more suitable for users who already have the skill of chopsticks. In another embodiment, the guide for guiding the thumb is provided not only with a contact surface that is in contact with the ulnar portion of the thumb but also with a contact surface that is in contact with the temporal side of the thumb, such that the guide is substantially It is semi-annular, and the two sides of the contact surface face the clamping end and the trailing end of the chopsticks respectively for defining the thumb side and the ulnar side. The first end of the semi-annular guide has a portion extending from the body toward the lower chopstick member, the extension reaching at least the front face of the lower mold member, forming a semi-tubular shape, and being integrated with the connecting member . Further, the ends of the above-described semi-annular thumb ergonomic device may be connected to the additional semi-annular members so that the guide members form a ring shape, the inner dimensions of which allow the fingers to be inserted. The first end of the guide member may have a portion extending from the body toward the lower chopstick member. The extension portion is at least as far as the front face of the lower chopstick member, forming a tubular shape and being integrally formed with the connecting member. In a consistent embodiment, the guide for guiding the thumb is spatially located in front of the upper chopstick part, the thumb guide is further provided with a crotch side guiding portion, and the «xan side guiding portion is spatially located on the upper chopstick part The front part is fixed to the upper side of the lower chopstick component through the connecting member, and the iliac crest side of the thumb section is guided by the thumb, the guide portion of the thumb member and the guide portion of the 桡 (four) guide portion The fingertip of the thumb section directly contacts the front of the upper chopstick part through the gap. The first end of the material member may have a portion extending from the body toward the lower zird σ [5 4 cattle, and the extending portion reaches at least the front portion of the lower mold TF1005038 8 201230990 sub-component, forming a tubular shape, benefiting and The connectors are united. The invention also includes a guide member that is directly mounted to the front of the lower chopstick member for the second side of the bow. This guide guides the relative position between the plump and the lower chopstick component and prevents the thumb from tilting too far toward the ruler side. And, in addition to the guide member, at least three additional bow guides may be included: a first one is fixed in front of the lower chopstick member for guiding the crotch side of the second section of the thumb, and the second is fixed in the In front of the upper chopstick member, a ruler (four) for guiding the first Φ of the thumb, and a third portion fixed in front of the upper pawn member for guiding the temporal side of the first section of the thumb. According to the invention, the 彳丨 guide of the index finger is in the form of a column, and the mouth is on the back of the lower sub-assembly, and the other end is away from the back of the lower sub-assembly, and the (10) anti-feed finger is used. The three-section movement is the end of the kinematic movement. The contact surface of the guide member of the next day may be 9 from the column. The jaw and the grip end extend to contact and guide the index finger of the second index of the index finger. The face may be (10) the front of the column guiding the palm of the hand, the contact and the guide or the guiding member of the weir are passed through the lower part of the lower mold part to the upper part and the invention does not define the guiding piece :部部: (4) A mold having the above-mentioned guides is feasible, constructed, and worn. TF1005038 201230990 In still another embodiment, a movable connecting device is disposed between the upper chopstick component and the lower chopstick component Having the upper and lower chopstick components spaced apart but relatively movable, t, the movable attachment means comprising a connecting rod and a shaft cooperating with the connection #, one end of the connecting rod being fixed to the The lower chopstick member has an open-ended c-shaped card interface at the other end, the shaft is disposed at the upper part of the upper sub-part, and the c-shaped card interface of the secret material is movably connected, and the movable connecting device is disposed. The upper chopsticks are allowed to be. The yak is pivoted relative to the lower chopstick member and deflected slightly, the pivoting causing the clamping of the upper and smuggling members to open or close relatively. The inner diameter of the card interface can be set to be larger than the diameter of the shaft so that the upper stream sub-assembly can be deflected slightly relative to the lower stream sub-assembly. The c妾, the inner cymbal and the shaft may be disposed at a position where the thumb is in contact with the upper chopstick member such that the position becomes an axis of rotation in which the upper chopstick member opens and closes relative to the lower sub-member. _ : The main solution to the problem of learning for beginners is to use a chopstick with a guide that can guide the third section of the thumb and forefinger to train the correct relative position and distance of the beginners. . In the learning process 1 two finger parts must be guided at the same time to achieve the training effect. This =_Ancai-_ refers to the guide and -. [Continuous application method] Location. The user's two hearts are the only ones that can press the hands in front of the two chopsticks. 'It is often important to keep the correct position and direction of the thumb. TF1005038 201230990 of the thumb The two parts of the chopsticks are fixed, so the human limbs used for the thumb are relative to the device. The fourth figure does not show an embodiment of the ergonomic device of the present invention, wherein a die is composed of a top member 1 and a lower mold member 2, and the lower mold member is provided with a body health device. The human body m has a guide member I33 for guiding the thumb, and the bow guide member is not directly mounted on the front face of the lower chopstick member, but is placed above the front face of the lower fill member, and is called by the connecting member (4) On the lower chopsticks part 2Q. Spatially, the guide is located between the upper chopstick component 1 and the lower chopstick component 20. The guide member 1331 has a substantially curved contact surface in contact with the side of the thumb. The bow I guide (3) 1 from the free end of the connecting member 131] to the rear end of the lower part and the mold part "extends and lie on the front of the upper and lower chopsticks, the curved surface of which faces the two streams The guide with a solitary surface (3) is located on the ulnar side of the thumb, preventing the ulnar side of the finger from being too squatting, "to reduce the thumb of the machine H and the body of the machine The contact between the engineering devices is natural and comfortable. Distance: Ben: The middle and the middle guides are separated from the lower pawn parts by the connecting piece - not limited to this, but also the shape of the η-" connector. Other suitable shapes, such as a cylinder, a flat cymbal = a sturdy curved body, etc., can be connected to the lower mold part as long as TF1005038 π can be attached. And, thanks to the guide:! Lower sub-components, instead of being fixed to the upper chopsticks, so the mold opening and closing = 201230990 The shaking caused by the upper chopsticks does not affect the relative position between the guide and the lower chopsticks, so the thumb can be guided. The part maintains a fixed relative position with the lower chopstick component. The guide member and the connecting member may be integrally formed or may be detachably mounted, and in general, a fixed relative position may be formed. Once the guide is installed, the lower chopstick part has two positions in contact with the thumb, which is the position where the guide piece is in contact with the ulnar side of the thumb, and the position of the front part of the lower chopstick part in contact with the second section of the thumb. . The two locations are spaced apart from each other to form a straight line that is substantially perpendicular to the lower chopstick component so as to guide the thumb to maintain a substantially vertical correct posture as shown in the first figure. Moreover, the guide member is spaced apart from the lower chopstick member by the connecting member, which is more effective for guiding the positioning of the thumb than directly disposed on the lower chopstick member body. As shown in the fifth figure, one hand can hold a pair of chopsticks in the correct posture by the ergonomic device of the embodiment of the present invention. The sixth to ninth drawings show various variations of the ergonomic device of the above embodiment, in which the same components are denoted by the same reference numerals, and the different components are represented by sequentially increasing angular codes in various variations. In the sixth figure, the length of the connecting member 13丨2 is longer than that of the connecting member 131! in the above embodiment, so that when the chopsticks are used, the thumb guiding member 1332 can reach the front face 11' of the upper chopstick member 10 such that the thumb guide The 1332 is capable of guiding the first section of the thumb to form a distance from the second section of the thumb that is in direct contact with the lower chopstick component so as to more effectively guide the positioning of the thumb. TF1005038 12 201230990 In the seventh figure, the _ body of the thumb guide 1333 is not only the sub-component and the _ position of the trait, but also the front 11° of the sub-material 丨0. In the eighth figure, the thumb guide is called downward.

In this embodiment, the connector is also limited to the guide member, and also makes the contact between the thumb and the guide member natural and comfortable with the lower chopstick member 20 short columnar body. The tenth to eighteenth figures are various variants of the embodiment of the ergonomic device shown in the tenth figure. The same components of the inn are denoted by the same S symbol, and the different components are in each view (four) handle. Increase (four) code representation. In the tenth figure, the thumb arch 1 guide 2 is fixed in the piece H by the connecting member 1012, and the length of the connecting piece is such that the semi-annular thumb-center guiding member can serve the front of the chopstick material 1G, and the thumb is used for guiding the thumb. One is. Alternatively, a resist member 145 may be provided on the back of the connector or the guide member, and the heart-resistance component is too close to the next scraper 2G. ^十—The semi-circular thumb arch guides 1〇33 in the figure are similar to the semi-bad thumb pieces in the tenth figure, and are listed as having a portion extending toward the lower chess piece. The thumb guide reaches the lower:::: and forms a semi-tubular 'for increasing contact with the plum: to enhance stability. In the eleventh figure, the semi-circular thumb piece in the tenth figure of the thumb guide 1034 is similar. The difference is that the part extending toward the mold part is attached to the TF1005038 201230990, so that The thumb guide reaches and extends beyond the front of the lower chopstick component to form a semi-tubular shape. In the fourteenth diagram, the semi-annular thumb guide 1035 is similar to the thumb guide 1〇32 in the eleventh figure, except that The thumb guide 1〇35 in the figure extends toward the lower mold member so as to reach the front surface of the lower mold member to form a semi-tubular shape. In the fifteenth® towel, the alkali guide member 6 is provided with a guide portion on the ulnar side of the secret thumb. Just 6 and the crotch side guiding portion 1〇26, the ulnar side guiding portion and the winding side are guided. The P knife spatially reaches the front η of the upper stream sub-assembly for guiding the ulnar side and the crotch side of the thumb=-section, the guide member It is fixed to the y chopsticks component through the connecting member 〇ΐ6, and a gap is provided between the two guiding portions, so that the money of the first section of the thumb is directly connected to the front of the treacherous component through the gap. Is the fifteenth _ change The thumb material is extended to the lower stream sub-assembly and reaches the front of the lower chopsticks member to form a semi-tubular shape. In the seventeenth, the fourteenth __, _lang guide is called a downward chopstick member extending to form a semi-tubular shape. However, the position f in the front center of the extended portion exposes the lower mold part so that the user can access the face of the blanking member. The ergonomic device of the eighteenth figure is tenth in the figure - The ergonomics "sets the difference", the ulnar side of the thumb guide, the guide portion just 9 is provided with an extension to reach the front of the lower mold part. The nineteenth figure is the deformation of the tenth figure, the difference In that, an additional half-ring TF100503 8 15 201230990 shaped member 111' is attached to both ends of the semi-annular thumb guide to form an annular thumb guide. The inner dimensions of the annular guide are adapted to fit over the thumb slightly loosely. Figures 20 and 21 are two variants of the ergonomic device of Figure 19. The annular thumb guide extends down the chopstick component to or beyond the front of the lower jaw member to form a tubular shape. Increase The contact range of the thumb guide and the thumb. Fig. 12 is a view showing still another embodiment of the ergonomic device of the present invention. A pair of the upper chopstick member 10 and the lower chopstick member 20 is not shown in Fig. 5. There is no ergonomic device on the chopsticks. The ergonomic device includes two guide members 2〇1, 2〇2 respectively disposed on the upper piece, and two guide members disposed on the lower chopstick member 20, These guides protrude from the two pieces. On the front of the P piece, the two guides on the same chopstick part are collectively configured to hold the cover card for guiding the thumb edge and the ruler side and defining them. In addition to setting the four guides at the same time, you can also choose to set only - to three guides, thousands of which are particularly important for the guide 203 located in the lower chopsticks component because this guide and the lower chopsticks component Relatively fixed, it can guide the relative position of the torsion finger side and the lower sub-member, and can also prevent the thumb from excessively tilting to the ruler side to reduce the possibility of holding the twist. In a variation of the ergonomic device shown in Fig. -4-M~卞1, the shape of the arch guide near the end of the lower chopsticks can be set to fit the ulnar side of the thumb.

According to the twenty-fourth figure, the human body figure of the present invention can be seen, the lower chopsticks are Qiu, and the three are straight. The back surface 23 of the child is close to the chopstick part = the guide on the back of the sub-assembly, the guide The piece is in the shape of a column, and the second part is fixed on the lower surface of the lower chopsticks portion 4 for centering. The back of the lower part of the lower part of the finger is guided by the position of the third section of the forefinger on the lower chopstick part. 'Prevent the bottom of the index finger too close to the continuation of the material. Open the twenty-fifth to the twenty-fourth, the saponin, and the completion of the work... The picture shows several variants of the ergonomics in the example shown in the fourteenth figure. In the fifteenth figure, the person is connected to the lower chopsticks part. The 510 pairs and the mold pair (4) m bottom and the portion 612 extending in the direction of the feeding member 10, the extending portion 61 TF1005038 A 2 of the 17 201230990 shape preferred with the index finger The three-section finger joint cooperates to facilitate the correct positioning of the index finger. The second one armor portion 62 can be selectively disposed at the bottom of the ergonomic device 6〇3, see the twenty-sixth figure, the second extension portion 62 The clamping end of the lower and downward facing chopstick member is inclined to match the lower portion of the index finger root, and the portion adjacent to the base of the index finger in front of the leather. Alternatively, the ergonomic device 6〇4 may include a guide member and The connecting member is fixed to the lower chopstick member by the connecting member 63 and protrudes from the back surface 23 of the lower chopstick member 20, and the guiding member is located between the upper chopstick member and the lower chopstick member 20 for guiding the third finger of the index finger As shown in Figure 27. Above In the embodiments shown in the twenty-fourth to twenty-seventh embodiments, the food ergonomic device is fixed to the lower chopstick member, and the advantage is that the ergonomic device does not open with the chopsticks. Instead, the chopsticks are swayed, but the lower chopsticks remain fixed so that the third section of the index finger is in the position defined by the sub-part. This allows the learner to feel the opening and closing without the index finger. The three-section (four) movement, the reception can avoid the learner's misunderstanding, mistakenly believe that the joints at the bottom of the index finger need to be exercised. The above embodiments are used to partially correct and guide the finger parts, such as the index finger or index finger. But for beginners In other words, the human body of the above embodiment is not sufficient for the beginner to fully grasp the correct posture of holding the chess. It is: Any of the above-mentioned implementations for the thumb (four) guide and any guide that will be placed on the index finger A chopstick for learning TF1005038 18 201230990 and an index finger, such as, but not limited to, combining the thumb guide of the fourth figure with the index finger guide of the twenty-fourth figure. In order to maintain the proper relative position of the thumb and the third section of the index finger, as shown in the first figure, the thumb is closer to the grip end of the chopstick than the third section of the index finger, thereby preventing the thumb from being too close to the third section of the index finger. This causes the problem of twisting the chopsticks as shown in the third figure. This function is very important for beginners. Alternatively, the thumb guide, the connecting piece, and the index finger guide group Φ can be combined to form a single body. An ergonomic device that simultaneously guides the thumb and forefinger to maintain the correct relative position of the thumb and forefinger to prevent distortion of the chopsticks as shown in Figure 3. For example, in Figures 28-30 Shown are front, bottom and back views of an embodiment of an integrated ergonomic device of the present invention. Figure 28 shows a front view of the ergonomic device, the ergonomic device being constituted by a guide member 10310 fixed to the lower chopstick member 20, the guide member having an irregular shape, the upper end of which reaches the upper chopsticks and the lower chopsticks portion • The position between the pieces, the lower end extends down the chopsticks and beyond the lower chopsticks. The guide has a curved surface for simultaneously defining the ulnar side and the temporal side of the thumb and conforming to the shape of the thumb. The guide member also has an irregular extension extending from a fixed portion thereof toward a bottom surface of the lower chopstick member, such that the surface of the irregular extending portion 117 substantially conforms to the shape of the connection position between the thumb and the index finger, facilitating the holder of the chopstick holder The chopsticks can be held comfortably, see Figures 29 and 30. As can be seen from the thirtieth aspect, the back surface of the ergonomic device has a contact surface that is in contact with and conforms to the third finger pad of the index finger. TF1005038 19 201230990 Alternatively, a movable connection can be provided between the upper chopstick part 1 〇 and the lower chopstick part 2〇 to define the distance between the two chopstick parts. The thirty-first through twenty-two figures are a variation of the ergonomic device shown in Figs. 28 to 30, wherein the main difference is that a movable connecting device is provided between the two chopsticks. Referring to the thirty-fourth diagram, the movable connecting device includes a connecting rod 93 and a shaft 91 that cooperates with the connecting rod. One end of the connecting rod is fixed to the upper surface 22 of the lower chopstick member, and the other end is a free end, and the free end is provided with a C-shaped card interface having an opening upwardly. The shaft 91 is disposed in a receiving groove 90 formed in the upper chopstick member, the receiving groove being designed to accommodate the c-shaped free end of the lower chopstick member and allowing the free end to properly move therein. The shaft 91 in the receiving groove 90 is for engaging the card interface of the connecting rod % so that the upper chopstick member can be pivoted relative to the lower chopstick member so that the grip end of the chopstick pair is opened or closed. The central opening of the C-shaped free end may also be sized to allow the free end to be slightly deflected relative to the shaft 91 because the inner diameter of the C-shaped card interface is larger than the diameter of the shaft, but the free end does not detach from the shaft. Rod, see the thirty-fifth' figure. k can train learners to rely on hand muscle coordination to prevent the side of the upper sub-component. Alternatively, the above-described movable connecting member can be applied to the pawn of any of the above-described embodiments. For example, on the lower chopstick component 20 which is simultaneously equipped with the thumb guide in the thirteenth diagram and the index finger guide in the twenty-fifth diagram, there is also an activity connection TF1005038 20 201230990 connector, such as the thirtieth, Show.
