Description

  The present invention relates to a sock obtained by tubular knitting with a sock knitting machine, and a method for manufacturing the sock.

  A general sock 1 as shown in FIG. 12 is tubular knitted from the entrance portion of the foot toward the toe portion 2, and is then attached to the end portion of the opening formed on the upper side 5 of the tubular knitted portion 3. Manufactured by doing. In FIG. 12, the attachment portion at the end of the opening is indicated by 6. The sock 1 shown in FIG. 12 is industrially a sock knitting machine, for example, a rotary operation shown in FIG. 14 in which a needle hook 60 around which a plurality of knitting needles 50 are arranged is rotated in a fixed direction and knitted. The needle hook 60 is knitted using a circular knitting machine that also has a turning operation for alternately turning the needle hook 60 in the forward and reverse directions.

  14- (a), the other end of the spatula 54 that opens and closes at one end of the collar 52 provided at the tip of the knitting needle 50 is rotated around a nail 56 provided at the neck of the collar 52. It is formed by being pivotally mounted. As shown in FIGS. 14B and 14C, a plurality of vertical grooves 64 are formed on the outer peripheral surface of the cylindrical member 62 that is the main body of the needle hook 60. A knitting needle 50 shown in a) is inserted so as to be movable up and down. When the needle hook 60 is rotated in a certain direction, the knitting needles 50 are sequentially lifted at predetermined positions to perform a knitting operation.

  A toe portion 2 of a conventional sock knitted by a circular knitting machine having a knitting needle 50 and a needle hook 60 shown in FIG. 14 is knitted by the procedure shown in FIG. After rotating the direction and knitting the tubular knitting portion 3 having a predetermined length, the needle hook 60 is rotated to knitting the toe portion 2 of the sock 1.

  When knitting the toe portion 2, after knitting to the AB position in FIG. 13- (c) showing the sole 4 of the sock 1, the needle pot 60 is rotated in the forward and reverse directions and involved in the knitting. The number of stitches of the knitting needle 50 to be knitted (hereinafter sometimes referred to as the number of stitches involved in knitting) is sequentially decreased and knitted to the CD position. After knitting to the CD position, the number of needles involved in the knitting is sequentially increased to the AB position in FIG. 13- (a) showing the upper side 5 of the sock while rotating the needle hook 60 in the forward and reverse directions. The toe portion 2 is formed by knitting.

  Further, after knitting to the AB position shown in FIG. 13- (a), an opening formed on the upper side 5 of the tubular knitting portion 3 while maintaining a predetermined number of needles involved in the knitting of the needle hook 60 The brazed portion 6 is formed by knitting up to the portion. Here, at the end edges of the sole side 4 and the instep side 5 of the toe portion 2, connecting lines AC and BD are formed in which a part of the loop forming each side is entangled with each other. The connecting lines AC and BD are also rotation ends when the needle hook 60 is rotated in the forward direction or the reverse direction.

  In the case of the sock 1 shown in FIG. 13, the number of needles when the toe part 2 is knitted by sequentially increasing or decreasing the number of needles involved in knitting while rotating the needle hook 60 of the circular knitting machine in the forward and reverse directions. Are substantially the same, the knitting direction of the circular knitting machine is constant in the direction of the center line of the sock 1. Accordingly, the toe portion 2 of the obtained sock 1 is symmetrical as shown in FIGS. 13- (a) and 13 (c), and is a view seen from the tip side of the toe portion 2 as shown in FIG. 13 (b). Therefore, the sock 1 has no difference between right and left.

  However, in general socks, the thumb is thicker than the other fingers, and the most advanced position of the foot is an asymmetrical shape located on the thumb side with respect to the center line of the sock 1, so the sock 1 shown in FIG. The shoe base is pulled by the thumb and a feeling of pressure is generated on the thumb side. In sports or the like where force is applied to the thumb, the thumb may feel pain during competition. Furthermore, since the shoe base is pulled by the thumb, the shoe base on the little finger side is also pulled, so that a feeling of pressure may also be felt on the little finger side.

  Paying attention to such problems of the symmetric socks, the applicant has previously proposed a sock having a shape suitable for an asymmetric foot (see Patent Document 1).

Japanese Patent Laid-Open No. 11-021703 (Claim 1, paragraphs 0007, 0013 to 0024, FIGS. 1 and 2)

  The sock of Patent Document 1 is an asymmetrical shape in which the most advanced position in the toe portion is biased toward the thumb side, and the knitted portion for increasing the thickness that increases the thickness of the toe portion is knitted toward the thumb side of the toe portion. It is characterized by. However, since the knitted portion for increasing the thickness is biased toward the thumb side, the foot that fits the sock is specified to have a thicker thumb side in the toe portion, so that the little finger side is about the same as the thumb side, for example. There is a possibility that it does not work for feet with thickness.

  From the above background, the present invention provides a sock that does not give a feeling of pressure to various forms of feet, such as a form in which the thumb side is thick, and the little finger side has a thickness that is almost the same as the thumb side. It is what we propose.

  The present invention is a set of a decreasing section consisting of a decreasing section where the number of stitches decreases from the sole side to the back side on each of the thumb side and the little finger side of the toe part and an increasing section where the number of stitches increases continuously. There is a plurality, and an end edge of the decreasing section and an end edge of the increasing section continuing to the end section are connected to each other. By connecting the edge of the decreasing section of the number of stitches and the edge of the increasing section continuous to each other, the edge of the increasing section and the edge of the decreasing section continuing thereto are not connected to each other. In FIG. 1- (a) below, on the developed view, the bottom is the sole side, and the top is the upper side.

  When knitting the toe part, the number of needles of the knitting needle 50 is gradually reduced as described above in order to make the tip part closed, but in claim 1 the number of needles is simply reduced. Rather, the thumb side and pinky side of the toe have multiple pairs of increasing sections consisting of a decreasing section of stitches and a continuous increasing section from the sole side to the upper side. The number of stitches is repeatedly reduced and increased on each side.

  On the developed view, as shown in FIG. 1- (a), the edges of the toe part on the thumb side and the little finger side are zigzag shaped, and when the knitting of the toe part is completed, that is, the edge of the section where the number of stitches is reduced. And the edge of the increasing section that is connected to it and the edge of the increasing section that is not connected to each other and the edge of the decreasing section that is connected to it are left as they are. Become. As a result, as shown in (b) and (c), substantially V-shaped or U-shaped connecting lines are formed on the thumb side and the little finger side, respectively. 1- (b) and (c) show the side surfaces of the thumb side and the little finger side, respectively.

  Since the edge of the increasing section of the number of stitches and the edge of the decreasing section continuous thereto are not connected to each other, a space in the thickness direction is secured at the toe portion when the knitting of the toe portion is completed. In this way, the connecting line of the edge that is substantially V-shaped or U-shaped gives a clearance without giving a feeling of pressure to the toe when the toe is put in the toe, and on the thumb side of the toe Has a function to increase the thickness on the thumb side, and has a function to increase the thickness on the little finger side on the little finger side.

  Since the connecting lines of the edges that are substantially V-shaped or U-shaped appear on the thumb side and the little finger side, the clearance at the toe portion is secured on both the thumb side and the little finger side. The size and position are freely set according to the number and size of V-shaped or U-shaped, that is, the number and size of the decreasing section and the increasing section.

  Therefore, regardless of the shape of the toe, such as whether the thumb side is thick or the little finger side is about the same thickness as the thumb side, socks that do not give the toes a pressure on various toes are formed. It becomes possible to do. Specifically, by increasing the number or size of V-shaped or U-shaped on the thumb side, the thumb side of the toe can correspond to a thick foot, and similarly on the little finger side, V-shaped or U-shaped By increasing the number and size of these, it is possible to cope with a foot having a thickness on the little finger side that is almost the same as that of the thumb side.

  In the present invention, at least on the thumb side, there are a plurality of sets of increase / decrease sections composed of the increase section and the decrease section continuous thereto. There may be a plurality of sets of increase / decrease sections on the little finger side.

  As shown in FIGS. 1- (a) and 3- (a), the set of increase / decrease sections refers to a set of edges that remain without being connected to each other, such as the V-shape and U-shape. And the edge of the decreasing section that follows it are a set. In claim 2, since there are a plurality of groups of increase / decrease sections on at least the thumb side, there are three or more decrease sections and increase sections as shown in FIG.

  In the present invention, since there are a plurality of sets of increase / decrease sections on at least the thumb side, the size and shape of the space for the above-mentioned toe portion can be freely formed, and in a wide range from the back side to the sole side of the toe. It is possible to secure a space. In particular, if there are multiple zigzags on the thumb side, the thumb side of the toes can easily accommodate thick feet, and if there are also multiple zigzags on the little finger side, the little finger side is about the same as the thumb side. It is possible to easily cope with a foot having a thickness.

  In the present invention, the number of sets of the increase / decrease sections on the thumb side is greater than the number of sets of the increase / decrease sections on the little finger side.

  In this case, as shown in FIG. 3, the number of sets of increase / decrease sections on the thumb side is larger than the number of sets of increase / decrease sections on the little finger side, so that the number of V-shaped or U-shaped formed on the thumb side Since the number is relatively larger than the number on the side and the space on the thumb side is increased, it is possible to easily relieve or eliminate the feeling of pressure especially on the foot having a thick thumb side. FIG. 3 shows a case where there are a plurality of increase / decrease sections on the thumb side, and a case where the number of pairs of increase / decrease sections on the thumb side is larger than the number of pairs of increase / decrease sections on the little finger side.

  The present invention is characterized in that among the plurality of increase / decrease sections on the thumb side, the number of increases or decreases in stitches in any increase / decrease section is smaller than the number of increases or decreases in stitches in other increase / decrease sections. And

  The increase or decrease of stitches in any increase / decrease section is less than the increase or decrease of stitches in another increase / decrease section means that the increase in stitches in any increase / decrease section is in other increase / decrease sections The number of stitches is less than the number of stitches, or the number of stitches decreases in any increase / decrease interval is less than the number of stitches decrease in other increase / decrease intervals, or the number of stitches increase and decrease in any increase / decrease interval is It means less than the number of stitches increasing and decreasing in the increase / decrease section.

  As shown in FIG. 6 (a), the increase or decrease of the stitches in any increase / decrease section on the thumb side is smaller than the increase or decrease of the stitches in the other increase / decrease sections. When the edge and the edge of the increasing section that is continuous with it are connected to each other, the edge of the decreasing section and the edge of the increasing section that are connected to the increasing / decreasing section with a small increase or decrease are connected. . As a result, as shown in (b), when the edge of another increase / decrease section with a large number of increases or decreases forms a V-shape or U-shape as described above, the V-shape or U-shape The edge of an increase / decrease section with a small increase number or a small decrease number appears in a V-shaped or U-shaped form at the tip position.

  Further V-shaped or U-shaped or the like is formed at the tip of the V-shaped or U-shaped formed on the thumb side, so that the space on the thumb side is further increased than in the case of claim 2 or 3. The effect of relaxing the feeling of pressure on the thumb side increases.

  According to the first aspect of the present invention, in each side of the toe portion on the thumb side and the little finger side, a decreasing section in which the number of stitches decreases from the sole side to the upper side, and an increasing section in which the number of stitches increases continuously. There is one increase / decrease section, and at least on the thumb side, there are a plurality of pairs of increase / decrease sections consisting of the increase section and the decrease section continuous thereto, and any one of the plurality of increase / decrease sections on the thumb side The increase or decrease of the stitches in the increase / decrease section is less than the increase or decrease of the stitches in the other increase / decrease sections, and the edges of the decrease sections and the edges of the increase sections that are connected to each other are connected to each other Is a constituent requirement.

  In the first aspect of the invention, as shown in FIG. 8- (a), there are a plurality of sets (decrease intervals) of a decreasing number of stitches and an increasing interval continuous from the sole side to the upper side on the little finger side. The case of singularity is included, and there may be no increase / decrease section. The invention according to claim 5 is the same as the invention according to claim 4 except that it includes a case where there is a single increase / decrease section on the little finger side. Therefore, it is possible to inherit the above-mentioned advantage of increasing the space on the thumb side, which the present invention has, and to easily eliminate the feeling of pressure on an asymmetrical foot whose toe shape is biased toward the thumb side.

  According to a second aspect of the present invention, in the first aspect of the present invention, an inclination angle of an edge of the decreasing section on the thumb side with respect to a traveling direction from the sole side to the upper side is the increasing section. It is a constituent requirement that the edge of the head is smaller than the inclination angle with respect to the traveling direction. As shown in FIG. 10- (a), the inclination angle α with respect to the traveling direction of the edge of the decreasing section indicates an acute angle, and the inclination angle β with respect to the traveling direction of the increasing section indicates an angle of 90 ° or less.

  In this case, the inclination angle α of the edge of the decrease section with respect to the traveling direction is smaller than the inclination angle β of the edge of the increase section. The angle (acute angle) between the center of the edge of the decreasing section or the line connecting the center of the edge of the decreasing section and the increasing section and the traveling direction is smaller than when the inclination angles of the end edges of the section are equal. That is, the line connecting the center of the edge of the decreasing section is biased toward the thumb side from the center line of the line connecting the thumb side and the little finger side. As a result, more threads are knitted on the thumb side than when the inclination angle of the edge of the decrease section is equal to the inclination angle of the edge of the increase section, so that the space on the thumb side in the toe portion can be thickened, The effect of relieving the feeling of pressure on the thumb is obtained.

  The sock according to claim 1 or 2 repeats the operation of decreasing and increasing the number of stitches from the sole side to the upper side on the thumb side and the little finger side as described in claim 3. Then, the toe part is knitted, and the edge of the reduced section in which the number of stitches is reduced is connected to the edge of the increased section in which the number of stitches is increased.

  In order to take over the benefits of the invention according to claim 1 or claim 2 by connecting the edge of the increasing section of the stitch number and the edge of the decreasing section continuous thereto, the thumb side is thick or the little finger side is Regardless of the shape of the toe, such as whether it has a thickness similar to that of the thumb side, it is possible to manufacture socks that do not give a feeling of pressure to the toe against various types of feet.

  On the thumb side and the little finger side, there are a plurality of sets of decreasing sections consisting of a decreasing section of the number of stitches from the sole side to the back side and an increasing section continuous thereto, or among a plurality of increasing / decreasing sections on the thumb side. Since the number of increase or decrease of the stitches in the increase / decrease section is smaller than the increase or decrease number of the stitches in the other increase / decrease sections, when the knitting of the toe part is completed, the toe part has a thickness direction. Space can be secured. Therefore, it is possible to provide a space that does not give the toes a feeling of pressure when the toes are put in the toes.

  The space can be secured on either the thumb side or the little finger side, and its size and position can be set freely, so whether the thumb side is thick or the little finger side is about the same thickness as the thumb side Regardless of the shape of the toe, etc., it is possible to avoid giving the toe a feeling of pressure with respect to various types of feet.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

  FIG. 1- (a) shows a decrease interval in which the number of stitches decreases from the sole side 4 to the upper side 5 on each of the thumb side 2a and the little finger side 2b of the toe portion 2, and the number of stitches continuously increases. There are a plurality of sets of increasing / decreasing sections consisting of increasing sections, and as shown in (b) and (c), the basics of the sock 1 in which the edge of the decreasing section and the edge of the increasing section continuous thereto are connected to each other The development view of a form is shown. In (a), the lower side indicates the sole side 4 and the upper side indicates the upper side 5. (B) Knitting the toe part 2 from the sole side 4 to the instep side 5 and ending the heeling on the instep side 5, the side of the thumb side 2 a in the toe part 2, (c) the little finger side The side of 2b is shown. In the toe part 2, the decreasing and increasing sections of the number of stitches are alternately repeated from the sole side 4 to the instep side 5, and the tip side of the tubular knitting part 3 shown in FIG. As a result, the braided portion 6 is formed as shown in FIGS. 1- (b) and (c).

  FIG. 1- (a) shows that while the knitting of the toe part 2 moves from the sole side 4 to the upper part side 5, there are two sections for decreasing and increasing the number of stitches on the thumb side 2a, and for the little finger side 2b. FIG. 5 also shows a development view in which there are two decreasing sections and increasing sections of the number of stitches. Since the decreasing section and the increasing section are alternately repeated, in FIG. 1, there are two increasing sections on each of the thumb side 2a and the little finger side 2b, and one increasing / decreasing section is obtained by repeating the two increasing sections. Will have. In FIG. 1- (a), HJH, H-L-H on the thumb side 2a, and I-K-I and I-M-I on the little finger side 2b are increasing intervals, and the thumb side 2a J-H-L and KI-M on the little finger side 2b are the increase / decrease sections.

  When the edges HJ, HL of the increasing section continuous with the respective edges HJ, HL of the decreasing section of the number of stitches on the thumb side 2a are connected to each other, the edge JH of the increasing section and the edge of the decreasing section continuous thereto are connected. HL (increase / decrease section J-HL) are not connected to each other, and on the thumb side 2a, the edge JH of the increase section and the end edge HL of the decrease section continuous thereto are paired and substantially V-shaped, or Appears in a U-shape. In the case of FIG. 1, a set of edges forming a V shape, a U shape, or the like, that is, an increase / decrease section is one set for both the thumb side 2a and the little finger side 2b.

  Similarly, when the edges KI and MI of the increasing section continuous with the edges IK and IM of the decreasing number of stitches on the little finger side 2b are connected to each other, the edge KI of the increasing section and the decreasing section of the increasing section are connected to each other. The edge IM (increase / decrease section K-IM) is not connected to each other, and on the little finger side 2b, the edge KI of the increase section and the edge IM of the decrease section continuous thereto are paired to form a substantially V shape. Or appear in a U-shape or the like.

  When the toe part 2 shown in FIG. 1 is knitted, after knitting up to the HI position in FIG. 2- (a) showing the sole side 4 of the sock 1, the number of stitches is sequentially set as shown in (b). It is reduced and knitted to the JK position. In this case, there are cases where the number of stitches reduced when the needle hook 60 is rotated in the forward direction and the number of stitches decreased when the needle hook 60 is rotated in the reverse direction are not substantially the same.

  The tubular knitting portion shown in FIG. 12 is rotated to a predetermined direction by rotating the needle hook 60 in a certain direction until the position of the line HI shown in FIGS. 1- (a), 2- (a), (b). After knitting 3, the toe portion 2 is knitted by alternately rotating the needle hook 60 in the forward and reverse directions and increasing or decreasing the number of stitches (number of stitches) of the knitting needles 50 involved in the knitting. The increase / decrease in the number of needles here is performed when the rotation direction of the needle hook 60 that rotates in the forward / reverse direction is changed.

  After knitting to the J-K position, as shown in FIG. 1- (a), when the needle hook 60 rotates to the J-position side, the stitches are sequentially increased and knitted to the H position, and at the same time the K position. When the needle hook 60 rotates to the side, the number of stitches is sequentially increased and knitted to the I position, and then when the needle hook 60 rotates to the H position, the number of stitches is decreased and knitted to the L position. At the same time, when the needle hook 60 rotates to the I position side, the number of stitches is reduced and knitting is performed to the M position side. A line HI connecting the H position and the I position during this period is a fold line from the sole side 4 to the upper side 5 as shown in FIG.

  In FIG. 1- (a), the number of stitches on the thumb side 2a and the little finger side 2b is made equal so that the sole side 4 and the instep side 5 are axisymmetric with respect to the fold line HI. This is not necessary, and the sole side 4 and the instep side 5 may be asymmetric with respect to the folding line HI. The same applies to FIGS. 3A to 7A.

  Further, in the case of FIG. 1, after knitting to the LM position, the number of stitches is sequentially increased at the L position side and the M position side, and knitting to the HI position is shown in FIG. Thus, the knitting of the toe portion 2 is completed. Here, the increased number of stitches when the needle hook 60 is rotated in the forward direction and the increased number of stitches when the needle hook 60 is rotated in the opposite direction may be substantially the same as or not the same.

  The toe portion 2 is knitted by moving from the sole side 4 to the instep side 5, but in the process until the heel portion 6 is formed, the needle reciprocates between the thumb side 2a and the little finger side 2b. , HI → JK → HI → LM → HI → HI. During this time, the number of stitches decreases in the process of H → J on the thumb side 2a, and the number of stitches increases in the process of J → H. The number of stitches decreases in the subsequent process of H → L, and the number of stitches increases in the process of L → H.

  Similarly, the number of stitches decreases in the process of I → K on the little finger side 2b, the number of stitches increases in the process of K → I, the number of stitches decreases in the process of I → M, and the stitches in the process of M → I. The number increases. In FIG. 1- (a), between the HI position on the sole side 4 and the HI position on the upper side 5, the number of decreases and increases in stitches on the thumb side 2a and the little finger side 2b are equal. JK and LM, which are connected by broken lines at points that proceed in the direction of transition from the sole side 4 to the instep side 5, are parallel to each other, but it is not always necessary to have such regularity. . The same applies to FIGS. 3A to 7A.

  FIG. 3- (a) shows a development view in the case where there are a plurality of sets of increase / decrease sections consisting of an increase section and a decrease section continuous thereto at least on the thumb side 2a. FIG. 3- (a) also shows a development view when the number of sets of increase / decrease sections on the thumb 2a side is larger than the number of sets of increase / decrease sections on the little finger side 2b. Specifically, while the knitting of the toe portion 2 moves from the sole side 4 to the upper side 5, there are three decreasing sections and increasing sections on the thumb side 2 a, and there are two sets of increasing / decreasing sections, The development view when there are two decreasing sections and increasing sections on the side 2b and there is one set of increasing / decreasing sections is shown.

  In the case of FIG. 3 as well, as shown in FIGS. 3B and 3C, the edges of the increased number of stitches and the edges of the decreasing area that are continuous with each other on the thumb side 2a and the little finger side 2b are substantially V-shaped. It will make a shape. On the thumb side 2a, there are two sets of increase / decrease sections, so that two V-shapes appear in a horizontal direction.

  When the toe portion 2 shown in FIG. 3 is knitted, the number of stitches of the knitting needles involved in the knitting (the number of stitches) is knitted to the HI position in FIG. 2- (a) showing the sole 4 of the sock. ) Are successively reduced to the J position on the thumb side 2a, and the K ′ position corresponding to the J position is knitted on the little finger side 2b. In FIG. 3, the number of stitches when the needle hook 60 is rotated in the forward direction and the number of stitches when the needle hook 60 is rotated in the reverse direction are not the same, but may be the same.

  After knitting to the J-K 'position, when the needle hook 60 rotates to the J position side, the number of stitches is sequentially increased and knitted to the H position. At the same time, the needle hook 60 rotates to the K' position side. Subsequently, the number of stitches is decreased and knitted to the K position, and the number of stitches is increased from the K position to the K ′ position. The K position corresponds to an intermediate point between the J-K 'position and the H-K' position with respect to the direction of knitting in the developed view.

Subsequently, when the needle hook 60 rotates to the H position side, the number of stitches is decreased and knitted to the L position. At the same time, when the needle hook 60 rotates to the K ′ position side, the number of stitches is increased. Knitting to the I position. Here, a line LI connecting the L position and the I position becomes a wrapping line from the sole side 4 to the upper side 5, and shifts to the upper side 5 after LI. After that, symmetrically with the sole 4, the number of stitches is increased on the thumb side 2 a through the increase interval (L → H) → the decrease interval (H → N) → the increase interval (N → H). The knitting is performed up to the HI position through the decreasing section (I → M ′) → the decreasing section (M ′ → M) → the increasing section (M → M ′) → the increasing section (M ′ → I).

  Also in this case, the toe portion 2 is knitted by moving from the sole side 4 to the upper side 5, but in the process until the heel portion 6 is formed, the needle reciprocates between the thumb side and the little finger side. On the other hand, it moves between HI, JK ', HK', LI, HM ', NM', and HI. Meanwhile, the number of stitches decreases in the process of H → J, H → L, and H → N on the thumb side 2a, and the number of stitches increases in the process of J → H, L → H, and N → H. Similarly, the number of stitches decreases in the process of I → K ′ → K and I → M ′ → M on the little finger side 2b, and the number of stitches increases in the process of K → K ′ → I and M → M ′ → I.

  The increasing sections J → H, L → H, and N → H, which are continuously connected to the decreasing sections H → J, H → L, and H → N on the thumb side 2a, are intertwined to form a connecting line. The increasing sections J → H and L → H and the decreasing sections H → L and H → N (increasing and decreasing sections JHL and LHN) are respectively paired, and FIG. A V-shape or the like on the thumb side 2a is formed as shown in FIG. Similarly, the decreasing sections I → K and I → M and the increasing sections K → I and M → I on the little finger side 2b are intertwined with each other to form a connecting line. Continuous decreasing sections I → M (increasing / decreasing sections K-IM) are paired to form a V-shape or the like on the thumb side 2a as shown in FIG.

  FIG. 4- (a) is a development view in the case where there are two sets of increase / decrease sections consisting of an increase section and a decrease section continuous thereto on the thumb side 2a and a pair of increase / decrease sections on the little finger side 2b, as in FIG. Indicates. FIG. 4- (a) also shows a development view in the case of performing knitting by increasing only the number of stitches without shifting from the sole side 4 to the upper side 5 in the increasing section on the thumb side 2a.

  Also in this case, as shown in FIG. 4- (b), on the thumb side 2a, the edge of the increased number of stitches and the edge of the decreasing interval continuous thereto (increase / decrease intervals OPQ, QPR) ) Is substantially V-shaped or the like, and as shown in (c), the edge of the increasing section of the number of stitches and the edge of the decreasing section continuous thereto (increase / decrease section K-IM) also on the little finger side 2b. Is substantially V-shaped or the like. On the thumb side 2a, two increasing / decreasing sections are continuous, so that there are two sets of edge portions that form a V-shape and the like, and two V-shaped portions appear in a horizontal direction.

  In the case of FIG. 4, after knitting to the HI position on the sole side 4, the number of stitches (number of stitches) involved in the knitting is sequentially decreased on the little finger side 2 b, and the thumb is knitted to the K position. On the side 2a, the number of knitting needles (number of stitches) involved in the knitting is sequentially decreased and knitted to the O position, and then the number of needles is increased without shifting to the upper side 5 and knitted to the P position. Is done.

  After knitting to the P-K position, the number of stitches is increased to the I position by increasing the number of stitches when the needle hook rotates to the K position side, and at the same time the number of stitches to rotate when the needle hook rotates to the P position side. Is reduced to Q position. Here, the line Q-I connecting the Q position and the I position becomes a fold line from the sole side 4 to the instep side 5, and after Q-I shifts to the instep side 5, so that it is symmetrical with the sole side 4 thereafter. On the thumb side 2a, the number of stitches increases (Q → P) → decreases (P → R) → increases (R → H). On the little finger 2b, the number of stitches decreases (I → M) → The knitting to the HI position is performed through the increased section (M → I). Also in this case, the toe part 2 is knitted as the needle moves from the sole side 4 to the upper side 5 while reciprocating between the thumb side 2a and the little finger side 2b.

  In FIG. 5- (a), as in FIG. 4- (a), there is one set of increase / decrease sections consisting of an increase section on the thumb side 2a and a decrease section continuous thereto, and one set of increase / decrease sections on the little finger side 2b. FIG. 4 shows a development view of the case, which corresponds to a case where the knitting method is performed without increasing or decreasing the number of stitches in the section of PQP in FIG. FIG. 5- (a) also corresponds to the modified example of FIG. 1 because the thumb side 2a and the little finger side 2b each have one increase / decrease section. In the increased number of stitches ST on the thumb side 2a, the needle does not move from the sole side 4 to the upper side 5, but only the number of stitches increases, and in the section THU after the increased section ST, the stitches increase. The needle moves to the upper side 5 without increasing or decreasing the number.

  In the case of FIG. 5, as shown in FIG. 5B, the edge ST of the increasing section of the number of stitches on the thumb side 2a and the edge UV of the decreasing section that is continuous across the edge THU of the section where there is no increase / decrease are substantially equal. A U-shape or the like is formed, and as shown in (c), the edge KI of the increased number of stitches on the little finger side 2b and the edge IM of the decreasing section continuous thereto substantially form a V-shape or the like. . There is one set of edges forming a U-shape or the like on the thumb side 2a.

  In this case, after knitting to the HI position on the sole side 4, the number of stitches (number of stitches) involved in the knitting is sequentially decreased on the little finger side 2 b and knitted to the K position while the thumb side 2 a. In knitting, the number of knitting needles (number of stitches) involved in knitting is sequentially decreased and knitted to the S position, and then the number of needles is increased and the knitting to the T position is performed without shifting to the upper side 5. Is called.

  After knitting to the TK position, when the needle hook rotates to the K position side of the little finger side 2b, the number of stitches is increased and knitted to the I position, and at the same time, the needle hook on the T position side of the thumb side 2a When turning, the knitting to the H position is performed without increasing or decreasing the number of stitches. Here, a line HI connecting the H position and the I position becomes a wrapping line from the sole side 4 to the upper side 5, and after HI, the line moves to the upper side 5. After that, knitting up to the U position without increasing / decreasing the number of stitches on the thumb side 2a symmetrically with the sole side 4, and then passing through a decreasing interval (U → V) → an increasing interval (V → H). In the little finger side 2b, the knitting is performed up to the HI position through a decreasing number of stitches (I → M) → an increasing interval (M → I). Also in this case, the toe part 2 is knitted as the needle moves from the sole side 4 to the upper side 5 while reciprocating between the thumb side 2a and the little finger side 2b.

  The edges HS and UV of the decreasing section on the thumb side 2a and the edges ST and VH of the increasing section that are continuous with each other form an intertwined connection line to form a connecting line, and the edge ST of the increasing section and the number of stitches The edge UV of the decreasing section that passes through THU without change forms a U-shape on the thumb side 2a as shown in FIG. Similarly, the edges KI and MI of the increasing section that are continuous with the edges IK and IM of the decreasing section on the little finger side 2b are intertwined with each other to form a connecting line, and are connected to the edge KI of the increasing section and the KI. The edge IM of the decreasing section to be paired forms a V-shape on the little finger side 2b as shown in FIG.

  6- (a) and FIG. 7- (a) are formed so that a V-shape is further formed at the tip of the V-shape formed on the thumb side 2a shown in each of FIGS. 1, 3, and 4 (b). The development view when there are a plurality of decreasing sections and increasing sections of the number of stitches is shown. 6- (b) and 7- (b) show the side surface of the thumb side 2a, respectively, and FIGS. 6- (c) and 7- (c) show the side surface of the little finger side 2b, respectively. In the case of FIGS. 6 and 7 as well, there are a large number (three sets) of edge groups that form a V-shape or the like on the thumb side 2a.

  In these cases, for example, in FIG. 6 (a), the number of stitches on the edge side where the number of stitches on the thumb side 2a forming the V-shape or the like increases, and the number of stitches on the edge of the edge where the number of stitches decreases continuously. Then, by making the increase / decrease number of the stitches of the edge eo where the number of stitches continuously increase and the edge oka continuously decreasing the number of stitches different from each other, as shown in FIG. A V-shape will be formed. In Fig.6- (a), the number of increase / decrease in the stitches of → → → → カ is double the number of increases / decreases in the stitches of エ → → → エ → エ → → → ク. And the decrease number is set arbitrarily.

  In the case of FIG. 6 (a), the edge eye of the decreasing section is connected to the edge Iu of the increasing section that is continuous with it, and at the same time, the edge edge of the decreasing section is connected to the edge eo of the increasing section that is continuous thereto. Then, a part of the edge eye near the A and a part of the edge Eo are connected to each other.

  FIG. 7- (a) shows a case where the number of increase / decrease sections on the thumb side 2a is increased so that the V-shape on the thumb side 2a having a V-shape at the tip in FIG. Yes. Specifically, in FIG. 6, there are three increase / decrease sections on the thumb side 2a, whereas in FIG. 7, seven increase / decrease sections are formed. Due to the relationship of forming a V-shape at the tip of the V-shape, the O-I line in FIG. 6- (a) and the Ka-I line in FIG. 7- (a) are folding lines from the sole side 4 to the upper side 5. Therefore, there are an odd number of increase / decrease sections.

  6 and 7, since a V-shape appears on the little finger side 2 b, one increase / decrease section is formed on the little finger side 2 b and there are two increase / decrease sections, whereas FIG. ) Shows a development view in the case where there is one decrease section and one increase section on the little finger side 2b in FIG. 6, there is no increase / decrease section, and there is one increase / decrease section. Similarly, FIG. 9A shows a development view in the case where there is one decrease section and one increase section on the little finger side 2b in FIG. 7, there is no increase / decrease section, and there is one decrease section. FIGS. 8B and 9B show the side surfaces of the thumb side 2a and the little finger side 2b, respectively.

  10- (a) and FIG. 11- (a) show an inclination angle (an edge of the decreasing section) with respect to the traveling direction from the sole side 4 to the upper side 5 of the edge (eye, etc.) of the decreasing section on the thumb side 2a. Development view when the angle α between the edge and the traveling direction is smaller than the angle of inclination of the edge of the increasing section (such as eg) with respect to the traveling direction (the angle β formed between the edge of the increasing section and the traveling direction). Indicates. In the drawing, the angle β formed by the edge of the increased section and the traveling direction is 90 °, and the angle β is not 90 ° or less, and the angle α is not shifted from the sole side 4 to the upper side 5 in the increased section. It needs to be larger.

  10- (a) and 11- (a), the edge of the thumb side 2a is inclined toward the middle between the thumb side 2a and the little finger side 2b from the sole side 4 to the folding line. However, this inclination is obtained by making the projected length of the edge of the decreasing section in the direction perpendicular to the traveling direction larger than the projected length of the edge of the increasing section in the direction orthogonal to the traveling direction. It is done. FIG. 10- (a) and FIG. 11- (a) also show that there are many decreasing and increasing sections on the thumb side 2a while the knitting of the toe part 2 moves from the sole side 4 to the upper side 5; This shows a case where there are two increase / decrease sections on the little finger side 2b and one increase / decrease section.

  As shown in FIGS. 10 and 11, when the knitting method is changed from the sole side 4 to the upper side 5 in the decreasing section of the stitches and not shifted from the sole side 4 to the upper side 5 in the increasing section, the thumb side is used. The angle between the center of the edge of the decreasing section of 2a, or the line connecting the center of the decreasing section and the edge of the increasing section, and the direction of travel does not include the increasing section, or in the increasing section from the sole side 4 to the upper side It becomes smaller than the case of shifting to 5. Accordingly, the shape of the toe portion 2 is biased toward the thumb side 2a, and a lot of yarn is knitted into the thumb side 2a. As a result, the space on the thumb side 2a in the toe portion 2 can be thickened. There is an advantage that can reduce the feeling.

  In the case of FIG. 10, the relationship between the increased section and the decreased section (A → H) on the thumb side 2a on the development view and the side surface of the thumb side 2a in a state where the knitting is completed is shown in FIG. As shown in FIG. 11 (b), the relationship between the increased section and the decreased section (A → N) on the thumb side 2a on the developed view in the case of FIG. 11 and the side surface of the thumb side 2a in a state where the knitting is completed. Is as shown in FIGS. 11- (a) and (b).

  In the case of FIG. 10- (a) and FIG. 11- (a), the edge of the increasing section on the thumb side 2a and the edge of the decreasing section continuous thereto are as shown in each (b) in a state where the knitting is completed. On the thumb side 2a, a large number of branches extend from one trunk. The line K connecting the position K and the W position in the case of FIG. 10- (a) is a wrapping line from the sole side 4 to the upper side 5, and the position and the W position in the case of FIG. The connecting line sheath W serves as a folding line from the sole side 4 to the upper side 5. In the case of FIGS. 10 and 11, there are a large number of sets of end edges of the increase / decrease section having a V-shape or the like on the thumb side 2a.

  Depending on whether the center of the increase / decrease section is located on the folding line key W from the sole side 4 to the instep side 5 (see FIG. 10) or the center of the decrease section (see FIG. 11). It is determined whether one V-character appears on the thumb side 2a as shown in FIG. 10- (b) or two V-characters appear as shown in FIG. 11- (b). 10 and 11, two increase / decrease sections are formed on the little finger side, and one increase / decrease section is formed. However, as in FIG. 8 and FIG. May not be formed.

  FIGS. 10 and 11 also show a case in which the number of stitches in the reduced section (A → I, etc.) on the thumb side 2a is smaller than the number of stitches in the decreased section (I → K) on the little finger side 2b. . In this case, since the inclination angle with respect to the traveling direction of the edge of the thumb side 2a is generally smaller than the inclination angle with respect to the traveling direction of the edge of the little finger 2b, the relationship with the projection length described in paragraphs 0070 to 0071 is the same. The effect is obtained.

  That is, the gradient of the line connecting the center of the edge of the thumb side 2a with respect to the direction of knitting from the sole side 4 or the back side 5 to the tip side of the toe part 2 is the edge of the little finger side 2b. The development of the toe part 2 becomes a shape that is biased toward the thumb side 2a with respect to the center line that faces the direction of knitting. As a result, it is possible to avoid giving a feeling of pressure to the asymmetrical foot in which the shape of the toe portion 2 is biased toward the thumb side 2a.
