Description
Learning to use chopsticks technical field
The present invention relates to a kind of chopsticks for being used to learn to hold chopsticks, in particular for the hinge of the ergonomic device of chopsticks, and connection chopsticks.Background technology
Chinese feed existing 3,000 years history using chopsticks.Chopsticks（Fig. 1) it is made up of the upper chopsticks part 10 and subassembly 20 of applying one's chopsticks to the food of column.The head 18 of upper chopsticks part and the head 28 for subassembly of applying one's chopsticks to the food are to clip food.The one side of upper chopsticks part and subassembly contact thumb of applying one's chopsticks to the food is referred to as above 11,21 (Fig. 1);One side 12,22 by the top is referred to as above；The one side of contact forefinger is referred to as the back side 13,23 (Fig. 2);Beneath one side is (not shown）Referred to as bottom surface.
However, the concrete shape of chopsticks is not limited to quadrangle, and can be polygon, circular, ellipse etc..Thumb is referred to as thumb oar side (33, Fig. 1) close to the side in hand forearm radius direction, and thumb is referred to as thumb ulnar side (34) close to the side in hand ulnar forearm direction.
The correct body position for holding chopsticks is shown by (Fig. 1).When holding chopsticks, the nameless support of first segment 36 is applied one's chopsticks to the food subassembly, and Section of three bottom of forefinger and following position 38 contact the back side for subassembly of applying one's chopsticks to the food, and thumb second knuckle 32 is pinned before subassembly of applying one's chopsticks to the food, and three positions stably clip subassembly of applying one's chopsticks to the food.Subassembly of applying one's chopsticks to the food is relatively fixed motionless with hand.In contrast, upper chopsticks part 10 is movable：Forefinger first knuckle and middle finger first knuckle clip the position that chopsticks part is closer to head, make above and below opening and closing movement, the downward chopsticks part of chopsticks part is opened and is closed up.And the first segment 31 of thumb according to upper chopsticks part before, the fulcrum as upper chopsticks part.The relative subassembly of applying one's chopsticks to the food of two finger joints of thumb is motionless.
Two finger joints of thumb are uniquely can be by the hand position that press against before two chopsticks.So, keep the correct position and direction of thumb extremely important.The relative subassembly of applying one's chopsticks to the food of two finger joints of thumb is all fixed, and institute should guide the relative position of the fixation of two finger joints of thumb and subassembly of applying one's chopsticks to the food for the ergonomic device of thumb.
It is passing to have had some auxiliary chopsticks.The thumb ergonomic device (such as groove or thumbhole) of these chopsticks is arranged on the body for subassembly of applying one's chopsticks to the food, it is impossible to the place for guiding thumb not contacted directly with subassembly of applying one's chopsticks to the food.
For example, United States Patent (USP) 5277464 discloses a kind of learning to use chopsticks, Chinese utility model confirms this
Patent CN87205972U, which is also disclosed that, a kind of similar holds chopsticks rectifier.The principle of these chopsticks is the sunk area that some finger shapes that coincide are set on the surface of two chopsticks, and the finger of chopsticks is held for guiding.Its weak point is, because these depressions are located at chopsticks in itself, the ergonomic device of chopsticks in itself is not protruded from, so these learning to use chopsticks are merely able to the place for guiding finger to be contacted in itself with chopsticks, but the place that finger can not be guided not contacted directly with chopsticks.
In another example, international patent application WO 2003/015589 discloses a kind of learning to use chopsticks.The subassembly of applying one's chopsticks to the food of the learning to use chopsticks is provided with thumbhole, and its weak point is that the thumbhole of the chopsticks is located at the body for subassembly of applying one's chopsticks to the food, it is impossible to the thumb position for guiding thumb not contacted directly with subassembly of applying one's chopsticks to the food, such as thumb first segment.
Beginner is easy to have a difficulty when holding chopsticks：They are not easy to grasp the relative position of Section three of thumb and forefinger, and are led to and hold chopsticks posture knob song（Fig. 3).During correct holding chopsticks (Fig. 1), thumb according to subassembly of applying one's chopsticks to the food before, the subassembly back side of applying one's chopsticks to the food is pinned in Section of three bottom of forefinger and following position 38：Section of three two sides in subassembly of applying one's chopsticks to the food of thumb and forefinger is relative；However, they with subassembly head 28 of applying one's chopsticks to the food distance and differ：Thumb is than head 28 of the forefinger third knuckle closer to subassembly of applying one's chopsticks to the food.Hold chopsticks beginner to be not easy to grasp this difference, it is directly relative that beginner, which easily takes for them,.This misunderstanding can make the afterbody 29 of the downward chopsticks part of thumb tilt, also the head 28 of the downward chopsticks part of forefinger third knuckle is made to tilt, thumb is mistakenly made to get too close to forefinger third knuckle (Fig. 3), order entirely holds chopsticks posture and is badly deformed and is unable to correct holding chopsticks.
In order to prevent this problem from occurring, we need guide thumb and forefinger third knuckle simultaneously, to train beginner to keep the correct relative position and distance of the two finger joints, prevent from holding chopsticks gesture distortion.However, the two finger joints must be directed to can be only achieved described training effect simultaneously.
There has been the aid that some hold chopsticks in past.In these instruments, there is a class to have position of the ergonomic device to guide thumb；It is another to there is a class to have position of the ergonomic device to guide Section three of forefinger.But, it is all these to hold chopsticks aid all not while the two finger joints are guided, so that failing training beginner correctly keeps the distance between Section three of thumb and forefinger.
For example, Japanese patent application publication No. 2005-177183, entitled " chopsticks has with subsidy " of invention, this application case discloses the chopsticks of a pair of study.Its weak point is that it can only guide the bottom of forefinger, without guiding thumb to be correctly oriented with position come by press against subassembly of applying one's chopsticks to the food.
In another example, international monopoly WO 2003/015589 recited above, a kind of disclosed
Chopsticks are commonly used, it is provided with thumbhole in subassembly of applying one's chopsticks to the food, to guide thumb.Its weak point is that it is not provided with the guide device of Section three of forefinger.
From above-mentioned instrument, conventional learning to use chopsticks only guides thumb or forefinger third knuckle, without guiding the two finger joints simultaneously.So, this kind of product of the prior art has not been able to effectively train learner to keep thumb with the relative position and distance of forefinger third knuckle to avoid holding chopsticks posture knob song（Fig. 3).
And some existing chopsticks learning tools of holding are with chopsticks part in hinge connection and subassembly of applying one's chopsticks to the food（Japanese patent application publication No. 2005-177183 and international monopoly WO2003/015589 as escribed above).The grade hinge may only be to a direction folding, it is to avoid beginner holds the problem of chopsticks distort.But also make beginner rely on this hinge, and the coordination of each muscle of hand can not be trained to make the correct folding of chopsticks.The content of the invention
The present invention is used to help that user's study is correct to hold chopsticks mode, i.e., as illustrated in FIG. 1.Therefore, of the invention provide a kind of learning to use chopsticks, thumb or/and forefinger third knuckle are guided using ergonomic device, training learner keeps what is gone out as shown in Figure 1 and Figure 2 correctly to hold chopsticks posture.Also, in order to train hand muscle to control the correct folding of chopsticks, the present invention also provides a kind of chopsticks hinge that can be deflected.
According to the first aspect of the invention there is provided including the thumb ergonomic device for chopsticks, to guide thumb to keep correct position.Thumb ergonomic device passes through fixing device (such as pillar）Subassembly of applying one's chopsticks to the food is fixedly connected to, makes the thumb ergonomic device be relatively fixed with subassembly of applying one's chopsticks to the food, to guide thumb and subassembly relatively fixed position of applying one's chopsticks to the food.The characteristics of this thumb ergonomic device is that itself is not contacted directly with subassembly of applying one's chopsticks to the food, and is fixed on subassembly of applying one's chopsticks to the food through fixing device.Because the thumb ergonomic device is not contacted directly with subassembly of applying one's chopsticks to the food, so the position that thumb is not contacted directly with subassembly of applying one's chopsticks to the food can be guided.
The position that guides thumb directly to be contacted with subassembly of applying one's chopsticks to the food is merely able on the contrary, those are existing, be directly installed on the ergonomic device for subassembly of applying one's chopsticks to the food (such as the thumbhole set by WO2003/015589).So, this design can more effectively guide the position and direction of thumb.
The present invention includes the thumb ergonomic device of an arc, for thumb ulnar side（Fig. 5, Fig. 6), the thumb ergonomic device is located at the top before subassembly of applying one's chopsticks to the food, and subassembly 20 of applying one's chopsticks to the food is fixed to by fixing device (such as pillar 131, Fig. 5).This ergonomic device can only contact thumb ulnar side, rather than guiding thumb both sides simultaneously, more difficult to beginner to grasp, but be adapted to had a certain degree of learner, for the side of concentration training thumb, and again
Amount can be lighter.The height of the fixing device is depended on, the position (Fig. 5) that this thumb ergonomic device can be fixed on chopsticks part between subassembly of applying one's chopsticks to the food, or be fixed on before chopsticks part（Fig. 6), or simultaneously the position (Fig. 7) between two chopsticks parts before upper chopsticks part is covered.Also, the thumb ergonomic device can set extension, downward chopsticks part extension, so that reaching before subassembly of applying one's chopsticks to the food（Fig. 9) or surmount before subassembly of applying one's chopsticks to the food（Figure 10), the face of arc is formed, to increase coverage.
