Detailed description of the invention

Next the present invention is discussed in detail by some specific embodiments with reference to accompanying drawing.It should be noted, shown embodiment and accompanying drawing for be chopsticks for right hand user and protrusion.But those skilled in the art can easily design the variant being suitable for left hand user, and these variants also belong in scope of the present invention.

Invention demonstrates a method be arranged in apply one's chopsticks to the food on subassembly for helping user to hold the structure etc. with the protrusion of chopsticks with correct posture.These protrusions are by contact position on hand or some positions.In this article, term " contact " means holding with in state at chopsticks, and protrusion is touched mutually with some positions on hand of user, and is maintained at some positions distance closely (that is, contacting loosely) on hand from user.

Fig. 5 shows first embodiment of the invention, and it is the top view of subassembly of applying one's chopsticks to the food, and wherein, Reference numeral 41,44 and 40 represents the cross section of the first nameless joint, the third knuckle of forefinger and the second knuckle of thumb respectively.As shown in the figure, two protrusions i.e. the first protrusion 51 and the second protrusion 54 being stored in is applied one's chopsticks to the food on subassembly, and both gives prominence to from the back side of subassembly of applying one's chopsticks to the food.These two protrusions can form as one with subassembly of applying one's chopsticks to the food, or are independent parts and are arranged on by traditional approach to apply one's chopsticks to the food on subassembly.Holding with in state at chopsticks, the first protrusion 51 contacts with the near zone in the first nameless joint 41, and the second protrusion 54 contacts with the finger abdomen of the third knuckle 44 of forefinger.This means that these two protrusions 51 and 54 contact with the position 1 and 4 of hand as shown in Figure 3 respectively.Like this, finger cannot be removed significantly from contact point, prevent joint 41 and dactylus 44 too close, and therefore can obtain stable and hold reliably and use posture.

Fig. 6 shows by finger-joint/dactylus 41,44 and 40 applied force.Three power schematically shown by arrow have very stably clamped subassembly of applying one's chopsticks to the food.In this case, finger-joint 41 and dactylus 44 can not move from subassembly of applying one's chopsticks to the food far-end 28 too far or too close to.Therefore, can hold in a secure fashion and use chopsticks.

Fig. 7 shows chopsticks parts and the back perspective view of subassembly of applying one's chopsticks to the food.In this embodiment, the first and second protrusions are respectively the form of bar 151 and bar 100.These two bars 151,100 are arranged in the back side of subassembly of applying one's chopsticks to the food, and exist simultaneously.An end of bar 100 and 151 is arranged on applies one's chopsticks to the food on the back side of subassembly, and the other end is stretched out from the back of subassembly of applying one's chopsticks to the food.

Fig. 8 to Figure 10 shows some other variants of Fig. 7.Specifically, Fig. 8 and Fig. 9 shows bar 151 and can arrange obliquely or obliquely; In other words, the angle that bar 151 can be different is stretched out from subassembly of applying one's chopsticks to the food.Figure 10 shows the shape that protrusion 151 can be embodied as other, such as plate.These variants also can be administered on bar 100.Certainly, also two protrusions can be embodied as the shape except bar or plate, as long as they can play the function of the first and second protrusions.

In another embodiment of the present invention, Connection Element can be arranged between the first and second protrusions, to connect this two protrusions, as shown in Figure 11 to 14.

Figure 11 shows Connection Element 62, and itself and the first protrusion 61 and the second protrusion 64 are integrated, and are therefore formed as one piece of rectangular slab on the whole.This platy structure can be observed better in Figure 12 of the back perspective view as Figure 11.

Except platy structure, Connection Element 62 and two protrusions can form a hemizonid on the whole.In this article, term " hemizonid " refers at itself and applies one's chopsticks to the food and define the structure of hollow space between subassembly, and it is not necessary for semicircular.Show this embodiment in figs. 13 and 14.In fig. 13, two protrusions 61,64 form a hemizonid on the whole together with Connection Element 62, and here, the shape of this hemizonid is rectangle.In fig. 14, two protrusions 61,64 form another hemizonid on the whole together with Connection Element 62, and here, the shape of this hemizonid is semicircle.These hemizonids also can be described to " roughly the structure of U-shaped ".Except the shape of rectangle or semicircle shape, also hemizonid can be designed to other shapes, such as polygon.

Figure 15 shows the back perspective view of hemizonid embodiment as shown in figure 14.Two ends 121 and 122 of hemizonid are arranged on applies one's chopsticks to the food on the back side of subassembly, and its circumferential section is given prominence to from the back side of subassembly of applying one's chopsticks to the food.One end 127 of hemizonid is used as the first protrusion, and its other end 129 is used as the second protrusion.Figure 16 is a kind of variant of Figure 15, and here, hemizonid and the space of applying one's chopsticks to the food between subassembly are filled, and makes to define one block of plate 115 on the whole.

Connection Element has following advantage.The first, Connection Element can stop problem as shown in figure 17, and the first namely nameless joint 41 can easily move in the position of mistake.In the position of this mistake, the first nameless joint 41 too close to the third knuckle of forefinger 44, and too close to the back side of subassembly of applying one's chopsticks to the food, causes can not stably holding with subassembly of applying one's chopsticks to the food.Therefore, the Connection Element 62 in Figure 11,13 and 14 can stop the first nameless joint 41 too close to the position of this mistake.The second, Connection Element 62 optionally contacts the near zone of nameless second joint.As shown in figure 18, the region 63 of Connection Element 62 can contact the near zone of nameless second joint, the position 2 of such as, hand in Fig. 3.By contacting the position 2 do not considered in existing chopstick structure, Connection Element 62 can provide extra support function, therefore promotes that forming correct holding uses posture.In addition, by arranging Connection Element, rigidity and the stability of protrusion can be improved, and outward appearance attractive in appearance can be obtained.

By adding expansion on hemizonid, the surface area of hemizonid can be increased.This hemizonid and this expansion can be merged into a part.Figure 19 shows such embodiment, on the top of hemizonid 204, wherein added a semicircular expansion 205.But hemizonid and expansion are not limited to semicircle.Such as, both all can be rectangle as shown in fig. 13 that.In a specific embodiment, expansion defines 1/4th spheroids 200 on hemizonid, as shown in figure 20.This 1/4th spheroid 200 can be seen as the multiple hemizonids be combined into one.This spheroid may be embodied to 1/4th positive spheroids, 1/4th spheroids, polyhedron (as Figure 31) or other similar shapes.As shown in the figure, the top edge 208 of 1/4th spheroids 200 above subassembly of applying one's chopsticks to the food outstanding.The far-end 201 of 1/4th spheroids 200 and rear end 202 are used as the first protrusion 51 and the second protrusion 54 separately.The region 211 that Figure 21 shows this 1/4th spheroid 200 can contact with the position 2 of the near zone of the second joint of the third finger, hand namely shown in Fig. 3, keeps this joint to be certain distance 215 with the back side of subassembly of applying one's chopsticks to the food.Figure 22 shows the top view of the embodiment of this 1/4th spheroid, and wherein the region 231,232,233 and 234 of this 1/4th spheroid 200 can contact with the finger abdomen (position 4 in Fig. 3) of the near zone (position 1 in Fig. 3) in the first joint of the third finger, the nameless near zone (position 2 in Fig. 3) of second joint, the finger abdomen (position 3 in Fig. 3) of the third knuckle of middle finger and the third knuckle of forefinger respectively.And region 236 can stop that the second knuckle of middle finger is too close to applying one's chopsticks to the food subassembly, namely prevents the position 6 in Fig. 3 too close to applying one's chopsticks to the food subassembly.Like this, user very stably can clamp chopsticks with correct posture.

In another aspect of this invention, propose a kind of for improving the relatively simple structure of holding chopsticks performance.Specifically, subassembly of applying one's chopsticks to the food is provided with the projection that can contact with the near zone of the second joint of the third finger (position 2 in Fig. 3).Figure 23 and Figure 24 shows an embodiment about this one side, and its king-rod 500 is given prominence to from the back side of subassembly of applying one's chopsticks to the food, and the free end 502 of bar 500 contacts (Figure 24) with the near zone of nameless second joint.Like this, the hand of user is also held Absorbable organic halogens and is used chopsticks.

This projection can exist as shown in Figure 23 and Figure 24.As an alternative, projection can be integrated with the as mentioned above first and/or second protrusion, but is not limited to this.Such as, Connection Element 62 can be used as projection, and is integrated with the first and second protrusions.In Figure 18 or Figure 21, the region 63,211 on Connection Element 62 contacts with the near zone of nameless second joint.Figure 15,16,20 and 22 shows more embodiment, and wherein region 128,118,209 and 232 contacts with the near zone of the second joint of the third finger respectively.In such cases, projection can be thought in region 63,211 or region 128,118,209 and 232.

Figure 25 shows another embodiment.The difference of the chopsticks shown in the chopsticks shown in Figure 25 and Figure 23 is only, plate 510 instead of bar 500 are given prominence to from the back side of subassembly of applying one's chopsticks to the food.Those skilled in the art can easily understand, and plate 510 can play the effect identical with bar 500.

For the embodiment with the projection contacted for the near zone of the second joint with the third finger, this embodiment has specific size alternatively.Figure 26 shows the top view of the embodiment for subassembly of applying one's chopsticks to the food.In the figure, the distance L1 represented by Reference numeral 701 is the distance on the top 65 from the back side of subassembly of applying one's chopsticks to the food to Connection Element 62, and the distance L2 represented by Reference numeral 702 is the distance of the far-end 28 from the intermediate point 66 between protrusion 61 and 64 to subassembly of applying one's chopsticks to the food.Their size may be selected to be the result making L1 be multiplied by 15 and is greater than L2, i.e. L1 × 15>L2.In another embodiment, the result that L1 is multiplied by ten is greater than L2, i.e. L1 × 10>L2.Similarly, in figure 27, the distance L1 ' represented by Reference numeral 711 is the distance of the free end from the back side of subassembly of applying one's chopsticks to the food to protruding 502, and the distance L2 ' represented by Reference numeral 712 is the distance from the intermediate point of protruding 502 to the far-end 28 of subassembly of applying one's chopsticks to the food.Their size may be selected to be the result making L1 ' be multiplied by 15 and is greater than L2 ', i.e. L1 ' × 15>L2 '.In another embodiment, the result that L1 ' is multiplied by ten is greater than L2 ', i.e. L1 ' × 10>L2 '.By selecting these sizes in the above range, the length of protrusion or the projection near zone be enough to the second joint of the third finger of most of user of can looking contacts, and therefore prevents this second joint too close to applying one's chopsticks to the food subassembly.

L1 and L2(or L1 ' and L2 ') size below can be selected respectively:

Adult sizes: 2.1cm and 15.5cm;

Juvenile size: 2cm and 13.5cm;

Child-sized: 1.8cm and 12cm; And

Baby's size: 1.6cm and 11cm.

Any one protrusion as above also can arrange expansion.The following provide two embodiments.

In one embodiment, as shown in Figure 28 and Figure 29, expansion 222 extends from the far-end of 1/4th spheroids.Expansion 222, from the far-end of 1/4th spheroids to downward-extension, increases the area contacted with the near zone in the first joint of the third finger.Therefore, can more stably hold with subassembly of applying one's chopsticks to the food.Also expansion 222 can be attached in the embodiment of other embodiments, such as hemizonid.

In another embodiment, Figure 30 shows 1/4th extra spheroids expanded below the embodiment of 1/4th spheroids, so just defines a hemisphere on the whole.This hemispheroidal surface giving prominence to below from subassembly of applying one's chopsticks to the food.Except the position contacted by 1/4th spheroids 200 in 1/4th spheroid embodiments, this hemisphere also can be shown in Fig. 3 with the position 5(of hand) contact.Which further improves the stability of holding with chopsticks.

And this embodiment can be improved as follows, the position 221 such as making 1/4th spheroids is flattened as shown in Figure 28 and Figure 29, so as with the mating shapes of the third finger.

Figure 31 shows another variant of 1/4th spheroid embodiments.In this variation, polyhedron 207 extends out from the top being arranged in the polygon hemizonid 206 of applying one's chopsticks to the food subassembly.Polyhedron 207 is long and narrow, and is used as 1/4th spheroids in the embodiment shown in Figure 20.In this article, term " polyhedron " is interpreted as belonging in the scope of term " 1/4th spheroids ".

All protrusions mentioned above and protruding being all arranged on are applied one's chopsticks to the food on the back side of subassembly.Installation method can include but not limited to: protrusion and subassembly of applying one's chopsticks to the food are integrated and therefore use injection moulding, or to be adhered to by protrusion by binding agent and to apply one's chopsticks to the food on subassembly.As an alternative, chopsticks insertion hand-hole can be made on protrusion, apply one's chopsticks to the food subassembly for insertion.In addition also station adapter can be used.This adapter has the hole for inserting subassembly 20 of applying one's chopsticks to the food, and above-mentioned protrusion can be installed on the back side of this adapter.Such as in US2011/0169286A1, disclose this adapter.

And, also can arrange other extra feature on chopsticks.Such as, the protrusion for thumb and/or other fingers can be added, or for connecting the hinge of two chopsticks.The embodiment of this respect can be found at WO2011/015033 or WO2003/015589.

Preferably, all have in the first protrusion embodiment above-mentioned, hold with under state at chopsticks, the first protrusion 51 all contacts the near zone of the finger abdomen in the first joint 41 of user's third finger, the position 1 namely shown in Fig. 3.

Preferably, hold with in state at chopsticks, the second knuckle 40 of thumb directly contact is applied one's chopsticks to the food before subassembly 20, and is in the position between the nameless finger abdomen in the first joint 41 and the finger abdomen of the third knuckle 44 of forefinger.This is clearly shown that by thickening line 801 in Figure 32.Figure 33 and 34 shows when this position 801 is one block of plate outstanding before subassembly 20 of applying one's chopsticks to the food in this example embodiment by barrier 802() stop.Now, the second knuckle 40 of thumb just cannot touch the tram 801 on before subassembly 20 of applying one's chopsticks to the food.Figure 33 shows the second knuckle 40 of thumb before the rear end in contact of barrier 802 applies one's chopsticks to the food subassembly 20, and Figure 34 shows the second knuckle 40 of thumb before the proximal contact of barrier 802 applies one's chopsticks to the food subassembly 20.These situations all result in that to hold chopsticks uncomfortable.

For this reason, preferably, on before subassembly of applying one's chopsticks to the food, corresponding to thing of not placing obstacles in the region between the first protrusion 51 and the second protrusion 54, so as to make the second knuckle 40 of thumb directly contact apply one's chopsticks to the food on before subassembly corresponding to the region between the first protrusion 51 and the second protrusion 54.For the embodiment of hemizonid, two ends of hemizonid can be considered the first protrusion 51 and the second protrusion 54, therefore in this case, preferably make the second knuckle 40 of thumb directly contact apply one's chopsticks to the food on before subassembly corresponding to the region between hemizonid two ends.Can obtain thus comfortable holding chopsticks posture.Preferably, the first protrusion 51 contacts the near zone of the finger abdomen in the first joint 41 of user's third finger, the position 1 namely shown in Fig. 3.

It should be noted that, the insignificant object of thickness, such as, can indicate the label etc. of the tram of the second knuckle of thumb, is not considered as this barrier.

Although according to some embodiments to invention has been detailed description, can be clear for those skilled in the art, can revise features/components/structures more of the present disclosure and change and do not depart from spirit or scope of the present disclosure.Particularly, unless caused conflict, otherwise disclosed feature all can combine with disclosed feature in other embodiments in one embodiment.The invention is intended to cover its all corrections and variant.
