Description

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

  In a general sock as shown in FIG. 10, after knitting a tube from the entrance portion of the foot toward the toe portion, the end portion of the opening formed on the back side of the tube knitting portion is attached (sewn). Manufactured by. In FIG. 10, reference numeral 26 denotes an anchoring (suture) portion.

  The sock shown in FIG. 10 is shown in FIG. 12, in which the needle hook 60 with a plurality of knitting needles 50 mounted around it is rotated (forward rotation) in a fixed direction and knitted to make the needle hook 60 forward and reverse. Are knitted using a circular knitting machine that also has a rotating operation of alternately rotating and knitting. As shown in FIG. 12- (a), the knitting needle 50 has a collar 52 provided at its tip, and the other end of the spatula 54 that opens and closes at one end is connected to a nail 56 provided at the neck of the collar 52. It is formed by being pivotally attached to the shaft.

  As shown in FIGS. 12B and 12C, a plurality of vertical grooves 64 are formed on the outer peripheral surface of the cylindrical member 62 which 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.

  In the toe portion 22 of the conventional sock using the circular knitting machine shown in FIG. 12, as shown in FIG. 11, the needle knives 50 are rotated in a fixed direction, and the tubular knitting portion 23 having a predetermined length is knitted. Thereafter, the toe portion 22 is knitted by rotating the needle hook 60 (forward rotation and reverse rotation).

  When the toe part 22 is knitted, after knitting to the AB position in FIG. 11- (c) showing the sole 24 of the sock 21, the needle hook 60 is rotated in the forward and reverse directions and involved in the knitting. The number of stitches of the knitting needle 50 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. 11- (a) showing the upper side 25 of the sock while rotating the needle hook 60 in the forward and reverse directions. The toe portion 22 is formed by knitting.

  Further, after knitting to the AB position shown in FIG. 11- (a), an opening formed on the upper side 25 of the tubular knitting portion 23 while maintaining a predetermined number of needles involved in the knitting of the needle hook 60 A brazed portion (stitched portion) 26 is formed by knitting up to the portion. Here, at the end edges of the sole side 24 and the instep side 25 of the toe part 22, connecting lines AC and BD are formed in which a part of a 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.

  Thus, in the case of the sock shown in FIG. 10, the sole portion is knitted in a cylinder together with the upper portion, the sole portion side is continuously folded back to the toe portion toward the upper portion side, and the folded toe portion Is sewn to the upper part. Since yarn for socks has sufficient tensile strength by being knitted, it is usually not necessary to use a yarn with a different thickness from the yarn for knitting the sole and instep for the toe. The same thread can be used for the entire sock.

  However, unlike socks, when knitting stockings with thin threads, for the purpose of preventing damage caused by the nails, the toes may use thicker threads than the threads that make up the soles and uppers. is there. For this reason, it is necessary to use a needle capable of sewing a thicker thread than the needle used for knitting, for the stitching of the toe part and the upper part composed of the thick thread.

  In use, since the tension acting on the toe portion increases in the length direction of the foot, the edge of the toe portion and the upper portion of the toe portion can be stitched together in order to withstand this tension. I need it. At this time, since the thread constituting the toe part is thicker than the thread constituting the sole and the upper part, it is necessary to use a needle that is stronger (thicker) than the needle used for tubular knitting. .

  Especially in stockings, the number of needles (threads) close to twice the number of needles (threads) used for socks (for example, 200 threads) (for example, 400 threads) is used. The density is higher than that of a sock, and the needle used for stitching the toe portion and the upper portion receives a large resistance at the time of stitching, not at the time of knitting.

  Therefore, it is considered that the needle used for the tubular knitting should be replaced with a thicker needle at the time of stitching. However, the needle hook 60 is provided with a knitting needle 50 having a specific size corresponding to the diameter of the needle. It is not possible to replace only the knitting needle 50 with the shuttle 60 in a drivable state. Therefore, in the knitting of stockings, the operation up to the final step “stitching the toe” cannot be performed with the needle hook 60 being used.

  From the above, when knitting stockings, after knitting the sole and upper part to the toe part, using a sewing machine different from the needle hook 60, the sole part and the toe part of the upper part are attached. The tips must be stacked and stitched together (see Patent Documents 1 and 2). This stitching is performed with the stocking turned upside down (see Patent Document 1).

Japanese Patent Laid-Open No. 8-27602 (paragraph 0020, FIGS. 1 and 4) JP 2001-355155 A (paragraph 0013, FIG. 1, FIG. 14, FIG. 15)

  At the time of suturing, the excess part of the sole and upper part is cut and removed, but this cutting line remains on the outer periphery side of the suture line with the suture thread, and in the use state where the foot is inserted in the stocking, Since the cutting line protrudes to the inside of the toe part, the cutting line or the suture thread may hit the finger of the toe and may feel uncomfortable or painful during use.

  In particular, the stitched part comes into contact with the tip of the toe with the nail removed, and that part receives tension in the length direction of the foot in use, and the tension is greater than the tension of other parts acting in the thickness direction of the foot. Because it is large, the longer it is used, the more painful it can be.

  In view of the above background, the present invention proposes a stocking in a form that does not give a sense of incongruity to the toes in use and a method for manufacturing the stocking.

  The stocking of Claim 1 has a toe part which covers a toe part and a back part, and a toe from the heel of a foot to a toe, and this toe part is either the said sole part or the above-mentioned back part. From one side, it continues to the other side of the sole and the upper part through the tip position of the toe, and it is stitched with the other side on the other side of the continuous tip And Here, the heel and toe of the foot refer to each part of the stocking corresponding to each position of the foot.

  When the toe part continues from one of the sole part or the back part to the other side of the sole part or the back part through the tip part of the toe part, the toe part passes from the sole part to the tip part of the toe part. There are cases where it continues to the upper side and cases where it continues from the upper part to the sole side through the tip position of the toe. In the former case, the toe part is sewn to the upper part on the upper part side, and in the latter case, the toe part is sewn to the sole part on the sole side.

  The stockings of the present invention include short stockings, pantyhose, non-garter stockings, tights, etc., mainly knitted with a thread thinner than socks, and have at least a part from the buttocks to the toes, This includes all thin socks that generate tension on the toes.

  The part of the stocking where the foot is inserted is tubular knitted in the same manner as the above socks except for the stitched part of the toe part and the upper part, and has a continuous shape in the circumferential direction. It consists of three parts: the upper part, the upper part, and the toe part.

  The circular knitting machine performs knitting before stitching, and a sewing machine different from the circular knitting machine is used for stitching the toe part and the upper part or the sole part. At the same time as the stitching, the excess part is cut. The toe part is stitched with the stocking turned upside down.

  The sole and back are knitted continuously by the rotating movement of the needle hook from the heel side to the toe side, but the tubular knitting stops at the stitching position on the upper side or the sole side, On the sole side or the back side opposite to the stitching position, the needle hook is continuously knitted up to the toe portion by the rotating (reciprocating) movement of the needle hook. As a result, the sole part or the upper part wraps around the toe part or the sole part side continuously to the toe part. A toe part is a part which wraps all the toes of a foot, and is formed in the bag-shaped solid shape which continued from the sole part to the upper part.

  The stitched part is located on the back side or sole side from the tip of the toe, and is formed at a position where the tip of the toe is removed. It will be in contact with the section up to the base of the foot, the back side, or the back side of the toes. As a result, the stitched portion does not come into contact with the tip of the toe, and the toe does not feel uncomfortable or painful or is relieved.

  As described above, since the toes receive a greater tension in the length direction of the toes from the toe portion than in the thickness direction, the pressure received by the tip of the toes becomes significant. On the other hand, in Claim 1, there is no seam at the tip of the toe part, and the toe part is formed in a bag-like three-dimensional shape that extends across the sole part and the upper part through the tip position of the toe part. It becomes possible to provide a margin in the thickness direction of the toes within the space in which the toes fit.

  This margin reduces the tension that can occur in the thickness direction or in the length direction when the stocking is in use. In particular, since there is no stitched part at the tip position of the toe, the tip position of the toe can follow the shape of the toes in use and can be rounded. The pressure in the direction is dispersed, and the feeling of pressure is relieved.

  Even when the thread (fabric) that constitutes the toe part is thicker than the thread that constitutes the sole part and the instep part, the stitching needle may penetrate the fabric in the sole part and the in part part. If possible, it is not necessary to perform special processing on the stitched portion.

  If the stitching needle cannot be penetrated with the sole and back fabric overlapped, the stitched fabric of the toe and back should be made thinner than the rest of the fabric. Is called. Since the fabric of the stitched portion is thin, it is possible to penetrate the stitching needle while overlapping the edges of the sole and the upper portion.

  The state in which the fabric of the stitched portion is thinner than that can be obtained, for example, by using a thread that is thinner than the thread used for the other portion of the stitched portion, or by increasing the thread density (degree).

  In the first aspect of the present invention, particularly when the toe portion has a larger volume closer to the thumb than the center line of the foot width as described in the second aspect, an effect of reducing the feeling of pressure applied to the toes can be obtained. . In this case, the left and right legs of the stocking including the toe portion have an asymmetric shape with respect to the center line of the foot width.

  The center line of the foot width refers to a straight line in the length direction of the foot that passes through the center in the width direction of the foot. That the volume of the toe portion is larger near the thumb than the center line of the foot width means that the toe portion has a portion that can swell as the toes are inserted at a position near the thumb. This swellable part is formed on one or both of the sole and the upper part.

  In the form in which the volume of the toe portion is larger than the center line of the foot width near the thumb, for example, as shown in claim 3, an extra thread (fabric) constituting the toe portion is knitted at a position near the thumb of the toe portion. Can be obtained. Or, as described in claim 4, at the position near the thumb of the toe portion, any one of roughening (enlarging) the stitch (degree) on the thumb side, changing the knitting structure, or changing the thread (thickness) It can be obtained by increasing the volume closer to the thumb.

  To change the knitting structure means to perform plain knitting that easily expands and contracts in a portion where the volume is increased, and mesh or rib knitting that does not easily expand and contract in other portions. In the third aspect of the present invention, extra yarn (fabric) is knitted on the thumb side of the toe portion by repeatedly increasing and decreasing the stitches mainly on the thumb side when the needle hook 60 is rotated to perform tube knitting. Is called. The increase / decrease of the stitches means that a section for increasing the number of stitches and a section for decreasing the number of stitches are formed as the knitting progresses as shown on the left side of FIG.

  In the second to fourth aspects, the toe portion has a large volume near the thumb and has a bulge, so that the toe portion has a shape that follows the shape of the toes as a whole in use as shown in FIG. Therefore, the tension in the thickness direction and the length direction of the foot applied to the thumb having a large length or thickness and the finger closer to the thumb is reduced, and the feeling of pressure received by the toe is further eased.

  Fig. 2- (b) shows a toe part of a conventional stocking. In the case of a toe part that does not bulge inside as shown here, the thumb side and the little finger side face the center side (middle finger side) of the toes. In order to receive pressure in the width direction of the foot, the toes are always pressed in the width direction of the foot. The thumb and little finger are forced to bend toward the middle finger as shown by the broken line.

  On the other hand, in Claims 2-4, by having a bulge in a toe part, as shown to Fig.2- (a), a toe can maintain the form before insertion even after insertion in a toe part. The thumb and the little finger are not subjected to pressure to bend toward the middle finger. The broken line in FIG. 2- (a) means that at least the thumb does not receive pressure toward the middle finger, and the little finger may not receive pressure toward the middle finger depending on the form of the bulge and the formation position. As a result, the thumb and the little finger feel free, so that the toes are not tired and stressed, and the hallux valgus is suppressed.

  The stocking according to any one of claims 1 to 4, mainly as described in claim 5, after knitting a section from the sole part to the stitched part of the upper part, toe part and upper part, Or it manufactures by stitching a sole part. “Cylinder knitting to the stitched portion” refers to knitting the stitched portion to the state before the stitched portion is stitched by the suture thread.

  In the vicinity of the stitched portion between the toe portion and the upper portion, or the sole portion, for example, a tube is knitted in a form in which a thin portion of the fabric is formed. As shown in FIG. 3, the stitched portion before stitching opens in a cylindrical shape, and the thin portion of the fabric is stitched to the tip (tip side) of the thin portion of the fabric of the stitched portion (cylindrical portion) at the time of stitching. In order to make it easy to extend in the axial direction of the (tubular portion), a thick portion of the fabric may be formed.

  In the case of the stockings according to claims 2 to 4, the toe portion is configured at a position near the thumb of the toe portion so that the volume of the toe portion becomes larger toward the thumb than the center line of the foot width as described above. While the yarn is excessively knitted, or includes a region where the size of the thumb side is increased, or a region where the knitting structure is changed, the tube is knitted to the stitched portion.

  It has a toe part that covers the toe part and the instep part, and the toes, and the toe part continues from the instep part or the toe part to the instep part side or the sole part side through the toe tip position. Since the upper part or the sole part is sutured at the tip, and the stitched part is formed at a position where the tip position of the toe part is removed, the stitched part does not contact the tip of the toe. As a result, it is possible to eliminate or relieve the feeling of discomfort and pain to the toes.

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

  FIG. 1 includes a sole part 2 and a back part 3 and a toe part 4 covering the toes from the toe to the toe, and the toe part 4 extends from either the sole part 2 or the back part 3. A specific example of the stocking 1 that continues to the other side of the sole 2 and the upper 3 through the tip position of the toe and is stitched to the other side on the other side of the continuous tip is shown. In FIG. 1, 5 indicates a stitched portion.

  The drawing shows a case where the toe part 4 continues from the sole 2 to the upper part 3 side through the tip of the toe, and is sewn to the upper part 3 on the upper part 3 side. To the sole 2 side, and may be sewn to the sole 2 on the sole 2 side. Below, it demonstrates centering on the case where the stitching | suture part 5 exists in the upper part 3. FIG.

  The sole part 2 and the instep part 3 are continuous in the length direction of the foot except for the stitching part 5, and are formed in a continuous shape in the circumferential direction by being knitted by rotation (forward rotation) of the needle hook 60 shown in FIG. However, there is no clear boundary between them. The sole part 2 (back part 3) and the back part 3 (sole part 2) are knitted to the stitching part 5 of the back part 3 (sole part 2) or to the front thereof, and the back part 3 (sole part 2) ), The toe portion 4 is knitted by repeating the rotation of the needle hook 60 (forward rotation and reverse rotation).

  Up to the stitched portion 5 is continuously knitted at least from the heel portion 6 of the foot in the length direction of the foot, but the starting position of the tube knitting is determined by the shape and length of the stocking 1. In the case of short stockings, tube knitting is started from a position near the knee of the heel, and in the case of pantyhose or non-garter stockings, it starts from the thigh.

  In order to impart the same strength to the toe portion 4 to the heel portion 6, a thread having a different thickness from that of the other portions may be used. In this case, the rotation of the same needle hook 60 ( The collar portion 6 is knitted by repeating the normal rotation and the reverse rotation). However, the heel portion 6 referred to in the present invention indicates a portion corresponding to the position of the heel of the foot, and does not necessarily have a three-dimensional shape corresponding to the shape of the heel. (A), it may not have the shape of a ridge as shown in FIG.

  When knitting the toe part 4, as shown in FIG. 9, in order to have a bulge near the thumb as shown in FIG. Enlarging (coarse) or changing the knitting structure is performed. The bulge near the thumb is formed on at least one of the sole side and the back side of the toe part 4 in at least a part of the area near the thumb, and may be formed near the little finger.

  6, 7, and 9 show examples in which the bulge is formed on both the sole side and the instep side of the toe portion 4, but may be formed only on either the sole side or the instep side. .

  In order to increase the degree of stitches (knitting) on the thumb side, it is necessary to increase the thread spacing of at least a part of either the sole side or the instep side of the toe part 4 or both of the other side areas. Is called. When changing the knitting structure, the yarn in a part of the toe portion 4 is similarly plain knitted, and the yarn in the other region is knitted with a rib or mesh.

  In any case, when the toes are inserted into the toe portion 4, the fabric can be stretched in at least one of the length direction and the width direction of the feet according to the size of each finger. It is sufficient that a part of the toe part 4 is knitted.

  For example, as shown in FIG. 6, the extra knitting of the yarn on the thumb side of the toe portion 4 means that, when knitting is performed by rotating the needle hook 60, on the thumb side, from the sole portion 2 side to the upper portion 3 side. The operation for increasing the number of stitches and the operation for decreasing the number of stitches are repeated once or several times. FIG. 6 is a development view of the toe portion 4 during knitting by rotating the needle hook 60. The left side shows the thumb side and the right side shows the little finger side. The arrow indicates the direction of progress of the knitting.

  As shown here, by repeating the operation to increase the number of stitches (B → C) and the operation to decrease (C → D) at least once on the thumb side, the fabric in the area indicated by hatching in FIG. Will be knitted extra. This excess fabric forms a bulge that is a large volume portion on the thumb side of the toe portion 4. The operation for increasing and decreasing the number of stitches may be performed on the little finger side. Here, the number of stitches (needles) to increase or decrease and the number of repetitions are arbitrary, and either one of the number of increase or decrease of stitches may be greater than the other.

  The edge of the section (A → B) where the number of stitches before the increase / decrease (B → C → D) is decreased, and the end of the section (B → C) where the number of stitches is increased continuously The edges are connected (sewn) to each other, and when the toe portion 4 in which knitting is completed is viewed from the front, a hatched region (B-C-D-F) in FIG. 6 appears as shown in FIG. Here, the decreasing section (the edge of A → B and the edge of the increasing section (B → C) connected to each other also appear in FIG.

  After the knitting of the toe portion 4, the stitched portion 5 shown in FIGS. 1 and 2- (a) is formed by the rotation (forward rotation) of the needle hook 60. The stitching portion 5 includes at least two strip-shaped belts, each of an inner section 51 continuous with the toe portion 4 using a yarn for knitting the toe portion 4 and a stitching section 52 using a thread thinner than the toe portion 4 for stitching. It consists of a section, and in the state before stitching, it has a cylindrical shape as shown in FIGS.

  In FIG. 2- (a), the two thin lines parallel to the length direction of the foot appearing on the upper 3 side (the surface side of the foot) are the stitched sections 52 between the thin lines. This shows that the suture section 52 extends in the length direction of the foot due to the insertion of the toes. As shown in FIG. 3, the tubular stitching portion 5 has a curved surface during knitting and has a shape in which both sides in the width direction of the foot are sunk. In addition, it is used as a guide when feeding to the sewing machine 70 side.

  In the drawing, in order to make it easy to reliably sew the suture section 52 during sewing, an outer section 53 is formed which is continuous with the distal end side of the suture section 52 and uses a thread thicker than the suture section 52, for example, a thread for the toe portion 4. ing. The outer section 53 is used to make the suture section 52 easy to extend in the axial direction of the cylinder when the tubular suture section 52 is overlapped and stitched.

  The stitching is performed by turning the stocking 1 in the state of FIG. 3 upside down and feeding the stitching section 52 of the stitching portion 5 to the sewing machine 70 as shown in FIG. . FIG. 5 shows a state in which the suturing is completed, but the suture thread 7 is sewn densely in the width direction of the foot or in a plurality of stages in the thickness direction so that the sewn section 52 is not separated.
