The present invention relates to a single-line interlocking hand stitching machine, in particular to a needle that can be used for a needle, and which is needled in the space inside the sewing machine floor. A single-line interlocking sewing machine that resembles hand stitching with white stitches. Forming method and sewing thread catching hook capture J so-called point/saddle stitch stitch forming method and

[Prior Art] A stitch is stitched on one side of the object to be sewn with one stitch to create a stitch and a visual needle. ISO 4915 Stitch Type 104 (chain line g

Stitch Type 2 09 (saddle stitch/hand stitch) In the past, it was well known that there is a needle inserted into the thread through which the needle is inserted, and a saturated needle on the side with a line catching hook. 104 ” stitch as a stitch stitch (similar to a stitch sewing machine that prevents the stitching of the star stitching (Document 1). This stitch sewing machine has a crochet hook that uses a stitch to catch the hook, so the stitch pitch has Disadvantages of the interval. In addition, in the sewing machine, although the air-side stitch is formed on the side, the original stitch is sewn on the lower side of the cloth, so that the operator is forced to perform the sewing operation, so that the spot stitch formation is confirmed. The traces of flickering are normalized by international standards )') and ISO 4915. One stitch, a curved needle, and a split stitch stitch of one stitch are formed, for example, by referring to a patented stitch and a side stitch and a crochet, and the stitch stitch formation on the cloth can be visually observed. The state is difficult to set up correctly -4-

200827505 (2) Disadvantages of sewing. And the sewing machine is stretched so that the stitches of the stitches are easily unwound, so that the function of the shifting of the cloth such as the star stitching is occupied. In order to solve this shortcoming, it is proposed to use a suture-guided yarn splitter with a line on the side of one stitch of the shuttle in which the package is wound, and a line-captured stitch guide and a similar point stitch of the celestial 1 04 ” stitch. For the similar hand stitches of the stitches, refer to Patent Document 2). Patent Document 1: Japanese Patent Publication No. 55-3 548 No. 1, FIG. 6 and FIG. 7) Patent Document 2: Japanese Special Fair 4-3234 Patent 4, 5 90, 878 (11th, 13th, and [Summary of the Invention] [Problems to be Solved by the Invention] In the hand-sewn sewing machine, in the sewing machine, a double stitch is formed in the stitch shape, and the cloth is placed on the lower side. In the hand stitch sewing machine, the needle guiding yarn splitter not only needs to be disposed on the supporting cloth, but the balance is disposed between the needle plate and the rotating needle cylinder, and the driving stitching must be configured. The mechanism, in the space of the limited sewing machine bottom plate, and the configuration on the sewing machine, the J "104" stitches are lost by preventing the above-mentioned crochet and wire built in the rotating syringe hook. Similar to the "sew sewing machine (such as the bulletin ( In the figure 5, the bulletin (=US figure 14), the upper side is formed with a stitch with a stitch stitch hook and a rotating needle, and the driving energy of the needle guide is specifically realized. The slit--200827505 (3) thread into the rotating syringe must be wound with the thread hook to the suture threaded by the rotating syringe onto the cloth. It is extremely dangerous for the operator to hold the above position on the cloth. There is a difficulty in forming a hindrance in the sewing work of the moving cloth. Therefore, it is impossible to implement the sewing machine similar to the hand stitching stitching, and when the sheet or the multi-layer cotton cloth or the patchwork is produced, the sewing is performed by hand work since ancient times. This requires a lot of man-hours, resulting in extremely heavy work. Therefore, use interlocking seams (ISO 4915 Stitch Type)

301) Sewing the sewing machine and using one of the two lines used as a transparent line to create a method for making hand stitches at first glance. However, the stitching basis of the sewing method is to use a chain stitch sewing machine to perform the sewing of the continuous thread, so that there is a pursuit of the sheet or the multi-layer cotton cloth or the patchwork after the sewing, along with the surface of the body to be sewn. The bumps and the inability to obtain softness of the original hand stitches sew the touch and visual difficulties. The present invention has been made in order to solve the above-mentioned difficulties, and provides a so-called point/saddle stitch in which a suture can be surely caught by a thread catching hook of a needle and a stitch is formed in a space inside the sewing machine bottom plate. For the purpose of forming a single-line interlocking stitch stitch forming method and a sewing machine similar to hand stitching, the present invention provides that the stitching can be surely captured by the needle catcher of the needle and stitch formation is performed in the space inside the sewing machine base. At the same time, it is possible to freely set the stitching pitch and the spacing between the stitches for the single-line stitching hand stitch forming method and the sewing machine. Further, the present invention provides a hand stitch stitch and a stitch stitch which are formed as a jump stitch group on the surface and the inner surface of the body to be sewn, and the direction of the stitched body is -6 - 200827505 (4), that is, the sewing direction is 1The jump stitch group is variable, and it can be used in the single-line interlocking stitching stitch forming method and sewing machine of the single or multi-layer cotton cloth or the patchwork. [Means for solving problems]

The principle of the invention is to provide a crochet with a line catching hook in a straight line in a vertical direction, a semi-rotating cylinder with a semi-rotational forward rotation and a semi-rotation reversal, a wire traction action member such as a reciprocating motion of a scorpion, and an elliptical motion transmission. Synergistically, the needle catching hook of the needle can surely capture the suture, and the space is formed in the space of the sewing machine bottom plate, and the hand stitch stitch and the interlock stitch stitch are respectively formed on the surface and the inner surface of the body to be sewn. Further, by the synergistic action of the crochet, the semi-rotating cylinder, and the wire pulling action member, when the hand stitch stitch and the stitch stitch are formed as the jump stitch group on the surface and the inner surface of the body to be sewn, the gear teeth are sewn. The transmission amount of the body is changed correspondingly to the stitch pitch transmission and the giant transmission between the stitches, and the stitch pitch and the stitch pitch can be freely set. The method for forming the single-line interlocking hand stitch of the present invention for achieving the above object is as follows: (a) a line catching hook is arranged on the side, and the crochet which reciprocates in a straight line in the vertical direction is placed from the top dead center through the first stroke. When the sewn body on the needle plate rises from the bottom dead center, the wire is wound under the needle plate and is taken out from the wire exit of the semi-rotation reversing syringe, and the line catching hook catches the line which is tightened at the crochet; b) When the crochet is disengaged from the object to be sewn in the first stroke and rises through the top dead center, the stitched body is driven by 1 stitch pitch, and the crochet of the catching line is raised by the 200827505 (5) and the syringe is further increased. (c) The crochet is lowered from the top dead center through the body to be sewn in the second stroke, and when the bottom dead point is raised, the hook is taken by the horn of the semi-rotating forward rotation cylinder. The captured line, while the captured line is released from the line catching hook by the rotation of the syringe; (d) the line that is taken by the needle horn horn is released by the rotation of the barrel and will be inserted into the syringe a line wound in the barrel of the syringe, the line through which the syringe is threaded

(e) During the second stroke, the crochet is detached from the object to be sewn and rises through the top dead center, and the sewed body is driven at a pitch of 1 stitch; (f) the steps of repeating (a) to (e) are sewed The surface of the body and the inner surface respectively form hand stitch stitches and interlocking stitches. According to the single-line interlocking stitching stitch forming method, the bobbin houses the bobbin case for storing the bobbin wound with the wire in the inner needle cylinder, and the bobbin case is rotatably mounted on the outer needle cylinder together with the inner needle barrel.

The pressing force of the pressing force adjusting spring 504 to the body 21 of the metal pressing member 501 can be adjusted by the rotation of the pressing force adjusting screw 508. Further, in order to move the metal pressing member 50 1 up and down, the upper push rod 605 which is engaged with the pressure bar holder 505 is rotatably provided on the upper push rod shaft 507 fixed to the arm 2. When the upper push rod 506 is raised, the pressure rod clamp 505 rises, and when it is lowered, the pressure rod clamp 505 -19-200827505 (17) is lowered. Therefore, the upper push rod 506 rises to form a space between the metal pressing member 501 and the needle plate 12, and the sewn body 21 is placed on the needle plate 12 to lower the upper push rod 506, and the sewn body 21 is The metal pressing member 501 is pressed against the needle plate 12, and the object to be sewn 2 1 can be set on the needle plate 12.

At the same time, during the second stroke, the crochet 13 is disengaged from the object to be sewn 21 and rises through the top dead center, and the transmission teeth 60 1 of the sewn body 21 are driven at a pitch of one stitch. The feeding mechanism 600 is fixed to the lower side of the needle plate 12 as shown in Figs. 2, 9 and 10, and the transmission teeth 601 are fixed to the substantially central portion of the transmission base 602. One end of the transmission base 602 is rotatably coupled to the horizontal transmission wrist 604 fixed to the horizontal transmission shaft 605 by a horizontal transmission wrist shaft 603. Therefore, the horizontally-rotating horizontal drive shaft 605 can swing the horizontal drive wrist 604 back and forth, so that the drive teeth 601 can reciprocate in the horizontal direction. Further, the other end of the transmission base 612 is fixed with an upper and lower transmission roller shaft 609, and the upper and lower transmission roller shaft 609 is provided with a freely rotatable upper and lower transmission rollers 608. The upper and lower driving rollers 608 are slidably inserted into the double fork portions 616a of the upper and lower transmission double forks 616 fixed to the upper and lower transmission shafts 613. Therefore, the reciprocating rotation of the upper and lower drive shafts 613 allows the upper and lower drive double forks 616 to swing back, so that the upper and lower drive rollers 608 embedded in the upper and lower drive double forks 616 can reciprocate the other end of the drive base 602 in the up and down direction. Here, as shown in Figs. 8(A), (B), and (C), the 1-stitch pitch P1 of the stitch drive is the length of the stitch of the hand stitch formed on the surface of the body 21 to be sewn, -20- 200827505 (18) The inter-pitch spacing P2 between the stitches is the length of the jump between two consecutive stitch stitches.

Rotating the horizontal drive shaft 6 0 5 as described above causes the reciprocating swing of the horizontal drive wrist 60 4 to reciprocate the drive base 602 in the horizontal direction, and the reciprocal rotation of the upper and lower drive shafts 613 causes the upper and lower drive double forks 616 to swing back and forth, embedding The upper and lower drive rollers 608 of the upper and lower transmission double forks 616 enable the transmission base 602

The other end moves back and forth in the up and down direction.

The wound stitch 20 (18th (G), 18th (H), 19th). At this time, the semi-rotating cylinder 200 has the bobbin 212 of the bobbin case 212 as shown in Fig. 20, and the crochet 13 is disposed to reversing the inner cylinder 205 of the semi-rotating cylinder 200 when it is lifted from the needle plate 12. From the direction and position in which the needle plate 12 is separated. Thereby, the suture 20 leading from the wire pulling action member 401 can be attached to the crochet 13 at the periphery. Further, when the crochet 13 is substantially moved from the top dead center (upper axis 5: 0 degrees) to the bottom dead center (upper axis 5: 1 80 degrees), the rotation of the semi-rotating cylinder 200 is stopped. The rotation of the semi-rotating cylinder 200 is stopped because the suture 20 is saturated on the line of the saturating needle 13 to capture the full 1 3 a in the first stroke, and the semi-rotation is rotated in the second stroke. The timing of the semi-rotation of the syringe is reversed. Further, the semi-rotating cylinder 200 starts the half rotation reversal after the crochet 13 is inserted into the body 21 (upper axis 5: 1 3 0 degrees) (the first 8 (E) 0 map, the 19th view). The wire pulling action member 401 is stopped at the most advanced position before the crochet 13 is inserted into the body 21 to be sewn (upper axis 5 · · 80 degrees) (Fig. 18 (D), Fig. 19). The cover pin 14 is formed in an open state when the crochet 13 is inserted into the body 21 to be sewn (Fig. 18(E), Fig. 19). The drive tooth 60 1 stops the feeding of the sewn body 21 before the crochet 13 is inserted into the body 21 to be sewn (Fig. 18(D), Fig. 19). (b) While the crochet 13 is detached from the object to be sewn 21 in the first stroke and rises through the top dead center (upper axis 5: 360 degrees), the sprocket 13 is driven by the transmission teeth 601 at the 1-stitch pitch of the body 21 to be sewn , the crochet 13 of the catching suture-33-200827505 (31) 20 is raised and the semi-rotating cylinder 200 is further reversed and the thread is wound up (18 (I) to 18 (()), 19th Figure). In addition, the semi-rotating cylinder 200 passes the top dead center at the crochet 13 (upper shaft 5

:36〇)) The semi-rotation reversal is stopped (upper axis 5:367 degrees) (18th (Μ), i9th). The wire pulling action member 40j can start the retracting swing when the crochet i3 reaches the bottom dead center (upper axis 5: 1 80 degrees), and can send the suture 20 (Fig. 18(f), Fig. 19), and the crochet 13 passes. The back point is stopped before the dead point (upper axis 5:3 60 degrees) (18th (L), 19th). When the crochet 13 moves from the bottom dead center (upper axis 5: 180 degrees) to the bottom dead center (upper axis 5: 366 degrees), the burr 13 passes through the needle plate 12 and the crochet 13 line The catching hook 1 3 a forms a closed state and passes through the stitched body 2 1 together with the crochet 1 3 (18th (1)th, 18th (1th), 19th). The transmission tooth 601 starts the 1 stitch pitch transmission before the crochet 13 passes the top dead center (upper shaft 5: 360 degrees) (the 1st 8th (L) map, the 19th (c) crochet 13 is in the 2nd stroke from the top The dead point (upper axis 5: 3 60 degrees) descends through the stitched body 21 (18th (N), 18th (0th), 19th), and the bottom dead center (upper axis 5: 540 degrees) When rising, the suture 20 captured by the thread catching hook 13a is extracted from the horn collar 205a of the semi-rotating cylinder 200 which is rotated halfway, and is released from the line catching hook 13a by the rotation of the semi-rotating cylinder 20. The captured suture 20 (the 18th (P) map, the 19th map). Further, the crochet 13 substantially moves from the top dead center (upper axis 5: 360 degrees) to the bottom dead center (upper axis 5: 540) When the rotation of the semi-rotating cylinder 200 is stopped, the rotation of the semi-rotating cylinder 200 is stopped by -34-200827505 (32) in the second stroke, and the hook i3a is caught from the line by the horn 205a of the syringe. The timing of hooking the hook of the crochet 13 to the catch hook 13 3a fishing line 20, and causing the semi-rotation reversal of the semi-rotation to rotate forward in the first stroke.

Further, the semi-rotating cylinder 200 starts the semi-rotation forward rotation when the crochet 13 reaches the bottom dead center (upper axis 5: 540 degrees) (Fig. 18(p), Fig. 19). The wire pulling action member 40 1 is inserted into the body 2] after the crochet 13 is inserted into the body 2, and then the needle 20 is fed backward (the first 8 (N) map, the 19th view). When the crochet 13 descends from the top dead center through the body 2 to be sewn, the thread catching hook 13a of the crochet 13 is opened (Fig. 18(0), Fig. 19). The transmission tooth 601 stops the 1 stitch pitch transmission before the crochet 13 is inserted into the body 21 to be sewn (the 18th (N)th, 19th). (d) The suture 20, which is rotated by the semi-rotating cylinder 200 to be pulled by the horn collar 205a of the semi-rotating cylinder 200, passes through the inner syringe driver spring 2 formed to fix the semi-rotating cylinder 200. The gap 〇2 between the other end of the inner syringe driver 2 0 3 and the inner syringe 2 0 5 is interlaced on the suture 20 wound on the semi-rotating cylinder 200, and will be formed at a fixed position. The inner needle cylinder driver 203 of the inner syringe driver spring 204 has a gap 20 that is passed through the gap 〇i between the end and the inner syringe 250, and is wound by the wire pulling action member 40 1 (first 8 (Q) Figure ~ 1 8 (W), Figure 19). In addition, the semi-rotating cylinder 200 stops the semi-rotation forward rotation while the crochet i 3 is detached from the body 21 to reach the top dead center (upper axis 5: 7 2 0 degrees) (different 18 (V) map, brother 19 picture). The wire pulling action member 4 () 1 starts to swing when the crochet pin 1 is detached from the body to be sewn 2 to wind up the suture -35 - 200827505 (33) 20 (18th (T), 19th). When the crochet 13 is raised from the lower dead point through the body 21 to be sewn, the needle catching hook 13a of the crochet 13 is closed (18th (T)th, 19th). The drive tooth 6 01 starts the 1st-pitch pitch transmission before the hoisting pin 13 passes the top dead center (upper axis 5: 720 degrees) (18th (W), 19th).

Therefore, the stitch 20 It can be surely caught by the thread catching hook 13a of the crochet 13, and the space inside the sewing machine base can be adapted to perform the stitching of a so-called point/saddle stitch of a so-called point/saddle stitch formed by a single-line stitch stitching. Sewing stitches and interlocking stitches are formed on the surface and the inner surface of the body 21 to be sewn. Therefore, it is possible for the operator to perform the sewing operation while visually checking the hand stitches on the surface, and the hand stitch can be confirmed. The stitching position can be accurately sewn. Further, since the hand stitch stitches and the stitch stitches are formed on the surface and the inner surface of the body 21 to be sewn, the stitches of the single stitch stitching stitches are not formed by the stretching. 20 makes it easy to unravel and obtain a firm sewing. The single-line interlocking hand stitch sewing machine can adjust the stitch pitch and the stitch distance by the transmission amount setting mechanism 300 and the transmission mode switching mechanism 350. For the transmission amount setting mechanism 300 and the transmission mode switching mechanism 3 5 0 The operation according to Fig. 21 to Fig. 24 is explained as follows. Fig. 21 to -36-200827505 (34) Fig. 24 is a diagram showing the transmission amount setting mechanism 300, the transmission mode switching mechanism 350, the feeding mechanism 600, and the feeding. FIG. 21 to FIG. 24, the stitch drive adjustment lever 301 and the inter-stitch transmission adjustment lever 302 are respectively swinged up and down, and are formed at the upper end point a' of the stitch drive adjustment lever 301. s, the upper end point of the inter-stitch transmission adjustment lever 3 0 2 respectively forms a minimum transmission pitch, the lower end point of the stitch transmission adjustment rod 3 〇1 a 'd, the needle

The lower end points ad of the inter-track transmission adjustment levers 302 are respectively formed to have a maximum transmission pitch. In the description of the operation, in the case of the display direction, the state shown in the direction of the drive tooth 60 1 is shown in Figs. 21 to 24 . <Example of minimum transmission setting of stitch transmission pitch and inter-stitch transmission pitch> First, for the case where the 1-stitch pitch of the stitch transmission and the 1-stitch pitch of the inter-stitch transmission are the minimum transmission, according to the second figure Description. When the operation stitch drive adjustment lever 3 0 1 and the inter-stitch transmission adjustment lever 3 02 are both the upper end points a's and as of the minimum transmission pitch, the operation stitch transmission adjustment lever 3 0 1 and the inter-stitch transmission adjustment lever are formed. The positions b' and b of the respective action points of the 3 02 are respectively located at the lowest point, so that the connected adjustment links 3 07', 3 07 respectively cause the reverse T-shaped transmission adjustment body 310 supported by the support wrist 311 to stand upright Moves down in the state. This moving position is made the lowermost position of the transmission adjusting body 1 。. When the reverse T-shaped transmission adjusting body 3 10 is in the lowermost position in the upright position, the shifting levers are respectively switched via the stitch pitch switching levers 35 5 that are pivoted at the longitudinal wrist ends of the reverse T-shaped transmission adjusting body 310 3 52 connection end 3 52a -37- 200827505 (35)

Pull down with the horizontal drive link 712. The moving position is formed to form the lowermost position of the coupling end 352a of the transmission switching lever 352 and the horizontal transmission coupling lever 712. In this state, the intermediate shaft 8 is eccentrically moved when the clockwise direction is rotated, so that the transmission switching lever 352 is displaced by the displacement amount Q between the left and right positions q, q' in the substantially horizontal direction. Intermittent swings. Further, the cam shape of the transmission switching cam 35 is a shape that can form the transmission switching lever 352 to be intermittently stopped at the moving positions q, q'. The intermittent stop time of the transmission switching lever 352 of the moving position q, q' is determined by switching the two-corner cam 35. Further, the intermediate shaft 8 is rotated by the row 1 during the two rotations of the upper shaft 5, so that the rotation of the upper shaft 1 causes the transmission switching lever 352 to move toward the moving position q, and the rotation of the upper shaft 5 causes the transmission switching lever 3 52 moves toward the moving position q'. When the transmission switching lever 3 52 moves in the right direction position q' and intermittently stops, the h point at the stitch end of the stitch pitch switching link 3 5 and the reverse T-shaped transmission adjusting body 3 1 0 which moves toward the lowermost position. The c' point of the other lateral wrist end 3 1 Ob coincides, and when the transmission switching lever 3 5 2 moves in the left direction position q and intermittently stops, the h point and the direction at the end of the stitch pitch switching link 3 5 5 The c-point of the lateral lateral end 310a of the reverse T-shaped transmission adjustment body 310 that moves at the lowermost position coincides. Therefore, the h point of the end of the horizontal transmission link 7 1 can be positioned at the lateral arm end 310a of the transmission adjustment body 310 respectively set by the stitch drive adjustment lever 310 and the inter-thread drive adjustment lever 302. The c point is at the c' point of the other lateral lateral end 310b, so that the setting of each of the sewn body transmission modes can be switched in sequence. The setting of each of the driven body transmission modes is performed by the transmission switching lever 352. The sewn body is fed in each of the -38-200827505 (36) transmission modes.

When the stitch transmission adjustment lever 301 and the inter-stack transmission adjustment lever 302 are respectively set to the minimum transmission pitch as described above, the first wrist 709a of the horizontal transmission coupling crank 709 is pulled downward toward the horizontal transmission coupling link 712 toward the clockwise direction. Turn. Therefore, the j point located at the lower end of the second wrist 70 9b of the horizontal drive crank 709 is swung to the left to stop. In this state, when the upper shaft 5 rotates in the clockwise direction, the eccentric amount e of the horizontal transmission eccentric cam 701 causes the horizontal transmission drive lever 702 to reciprocate in a substantially horizontal direction, and thus is coupled to the second wrist 709b of the horizontal transmission crank 709. The horizontal transmission lever 707 has a swinging center at the j point of one end, and swings the horizontal transmission longitudinal rod 704 coupled to the other end of the horizontal transmission lever link 7〇7 in the left-right direction. Further, the position at which the second wrist 709b of the horizontal drive crank 709 is swung to the left and stopped is set such that the j point of the end of the horizontal transmission link 707 coincides with the swing center position of the horizontal transmission longitudinal rod 704, even if the horizontal transmission eccentricity is transmitted. The eccentric amount e of the cam 701 still causes the center of oscillation of the horizontal transmission link 707 to overlap with the center of oscillation of the horizontal transmission longitudinal rod 704, so that the up and down motion transmitted to the horizontal transmission longitudinal rod 704 is extremely minute. Therefore, in each of the sewn body transmission modes, the horizontal transmission amount of the transmission teeth 601 is not generated to cause the sewn body 21 to form a minimum transmission. <Maximum drive setting example of the stitch transmission pitch and the inter-stitch transmission pitch> Next, the case of the maximum transmission of the 1-stitch pitch of the stitch drive and the 1-stitch pitch between the stitches is explained according to Fig. 22 . -39- 200827505 (37) Operation of the stitch drive adjustment lever 3 0 1 and the inter-stitch transmission adjustment lever 3 02 when both sides are also set at the lower end point a'd, ad of the maximum transmission pitch 'forms the stitch transmission adjustment lever 301 And the positions b, b of the respective action points of the inter-stitch transmission adjustment lever 302 are respectively at the uppermost point, so that the connected adjustment lever links 307, 3 07 are respectively inverted T characters supported by the support wrist 311 The type transmission adjusting body 310 moves upward in an upright state. This moving position is formed as the uppermost position of the transmission adjusting body 310.

When the inverted T-shaped transmission adjusting body 3 10 is in the uppermost position in the upright state, the link 3 5 5 is switched via the stitch pitch of the longitudinal wrist end 3 1 0 c of the transmission adjustment body 310 of the reverse T-shape. The connecting end 35 2a of the transmission switching lever 35 2 and the horizontal transmission connecting link 712 are respectively pushed upward. This moving position is formed to form the uppermost position of the coupling end 3 52a of the transmission switching lever 3 52 and the horizontal transmission coupling link 712. In this state, when the intermediate shaft 8 is rotated in the clockwise direction, as in the above-described setting example of the minimum transmission, since the transmission switching cam 3151 performs the eccentric motion, the transmission switching lever 3 52 can be formed substantially The left and right positions q and q' in the horizontal direction are intermittently oscillated by the displacement amount Q. Further, the cam shape of the transmission switching cam 351 is a shape that forms the transmission switching lever 352 at which the movement positions q, q' can be intermittently stopped. The intermittent stop time of the transmission switching lever 3 52 that moves the positions q, q is determined by the transmission switching cam 351. Moreover, the intermediate shaft 8 performs 1 rotation during the two rotations of the upper shaft 5, and the rotation of the upper shaft 1 causes the transmission switching lever 3 52 to move toward the moving position q, and the rotation of the transmission shaft 352 is caused by the rotation of the upper shaft 1 Move position q' to move. When the transmission switching lever 3 5 2 moves to the right direction position q ' and intermittently stops -40-200827505 (38), the stitch pitch switching link 3 5 5 end of the h point and the reverse T shape moved to the uppermost position When the c' point of the other lateral arm end 310b of the transmission adjusting body 310 coincides, and the transmission switching lever 3 52 moves to the left direction position q to intermittently stop, the stitch pitch switching link 3 5 5 ends - shift and shift Move to

The c-point of the reverse T-shaped transmission adjustment body 3 10 at the uppermost position of the lateral lateral wrist end 3 1 0a coincides. Therefore, the h point of the horizontal transmission link link 7 1 2 end can be positioned at the lateral arm end 3 10a of the transmission adjustment body 3 10 respectively set by the stitch drive adjustment lever 301 and the inter-stack transmission adjustment lever 302. The point c is at the point c' of the other lateral wrist end 310b, so that the setting of each of the driven body transmission modes can be switched in sequence. The setting of each of the sewn body transmission modes is performed by the transmission switching lever 352. Each of the sewn body drive modes performs feeding. When the stitch drive adjustment lever 301 and the inter-track drive adjustment lever 302 are respectively set to the maximum transmission pitch, the first wrist 709a of the horizontal transmission coupling crank 709 is pushed up by the horizontal transmission link 712 toward the reverse φ clock. The direction is rotated. Therefore, the j point at the lower end of the second wrist 709b of the horizontal drive crank 709 is swung to the right and stopped. In this state, when the upper shaft 5 is rotated in the clockwise direction, the eccentric amount e of the horizontal transmission eccentric cam 70 1 causes the horizontal transmission driving lever 702 to reciprocate in a substantially horizontal direction, so the horizontal transmission eccentric cam 70 1 When the eccentric rotation moves in the left direction, the other end of the horizontal transmission lever 707 is swayed to the left by the horizontal drive lever 702, and the horizontal drive eccentric cam 7 〇1 is eccentrically rotated toward the right, by the horizontal drive lever 702. The other end of the transmission rod link 707 swings upward toward the right. As a result, the reciprocating motion of the horizontal drive drive lever's reciprocating -41 - 200827505 (39) oscillating motion is converted to the maximum vertical direction to the horizontal transmission longitudinal rod 704. Therefore, in each of the bodies to be sewn, the horizontal transmission amount of the transmission teeth 60 1 forms a maximum pitch to feed the body 21 to be sewn at the maximum pitch. <Setting example of minimum stitching pitch and maximum pitch between stitches >

Next, as shown in the figure 8 (B), the 1 stitch pitch P1 for the stitch drive is the minimum drive, and the 1 stitch pitch P2 between the stitches is the maximum drive according to the 23rd (A), (B) Figure description. As shown in the 23rd (A) diagram, the set stitch drive adjustment lever 3 〇1 is the uppermost point a's of the minimum transmission pitch, and the inter-stitch transmission adjustment lever 3 02 is the lowest point of the maximum transmission pitch as, the needle is formed. The position of the action point of the track transmission adjustment lever 3 0 1 is the lowest point, and the position b at which the action point of the inter-stitch transmission adjustment lever 3 02 is formed is at the uppermost point. The adjustment lever link 3 07' coupled to the stitch drive adjustment lever 301 pulls down the other lateral wrist end 310b of the reverse T-shaped transmission adjustment body 310, and is coupled to the adjustment lever link 3 of the inter-stitch transmission adjustment lever 302. 07 is to push up the reverse T-shaped transmission adjustment body 3 1 0 - the lateral wrist end 3 10a. As a result, the reverse T-shaped transmission adjusting body 3 1 〇 is rotated in the clockwise direction centering on the pivot point d supported by the support wrist 31 1 . In its state, the longitudinal wrist end 3 10c of the reverse T-shaped transmission adjusting body 3 10 is inclined toward the right direction, and the stitch pitch switching link 35 5 connected to the longitudinal wrist end 3 10c is oriented toward the clockwise direction due to the intermediate shaft 8 The direction rotation causes the transmission-42-200827505 (40) to switch the cam cam 3 5 1 eccentric motion, so that the transmission switching lever 3 52 moves to the left direction position q intermittently stops, the stitch spacing switch link 3 5 5 end - h point It coincides with the point c of the lateral wrist end 3 1 0 a of the reverse T-shaped transmission adjustment body 310 that rotates in the clockwise direction. That is, the h-point of the stitch pitch switching link 3 5 5 - the end is moved clockwise to the upper left centering on the joint pin 3 1 2 . Therefore, the link pitch switching link 355 is connected

The other horizontal transmission link 712 is pushed up. The first wrist 709a coupled to the horizontal transmission link crank 709 of the horizontal transmission link 712 is pushed up in the counterclockwise direction. Therefore, the j point of the lower end of the second wrist 709b of the horizontal transmission coupling crank 709 is swung to the right and stopped. In this state, when the upper shaft 5 is rotated in the clockwise direction, the eccentric amount e of the horizontal transmission eccentric cam 70 1 causes the horizontal transmission drive lever 702 to reciprocate in a substantially horizontal direction. Therefore, the horizontal transmission eccentric cam 7 0 1 is directed to the left. When the square eccentric rotation movement is performed, the other end I of the horizontal transmission dare link 707 is swayed to the left by the horizontal transmission driving lever 702, and the horizontal transmission eccentric cam 701 is eccentrically rotated toward the right side, and is driven by the horizontal transmission driving rod 702. The other end I of the horizontal transmission lever link 707 swings upward to the right to stop. As a result, the reciprocating motion of the horizontal transmission drive lever 702 is converted into the maximum up and down direction of the reciprocating motion to be transmitted to the horizontal transmission longitudinal rod 704. Therefore, the transmission between the stitches set by the inter-stitch transmission adjustment lever 302 forms the transmission amount of the maximum transmission pitch. On the other hand, as shown in Fig. 23(B), the longitudinal wrist end 3 1 0c of the reverse T-shaped transmission adjusting body 3 10 is inclined to the right, and the stitch pitch switching connection of the longitudinal wrist end 3 1 0c is connected. Rod 3 5 5, intermediate shaft 8 facing clockwise -43- 200827505 (41)

When the rotation is such that the transmission switching cam 351 is eccentrically moved, and the transmission switching lever 3 52 is moved to the right direction position q' to intermittently stop, the stitch point is switched to the opposite point of the h point of the link 355 and the clockwise direction. The c5 point of the other lateral arm end 310b of the font transmission adjustment body 310 coincides. That is, the h point of the stitch pitch switching link 3 5 5 end is rotated in the counterclockwise direction about the connecting pin 312 and moved to the lower right side. Therefore, the horizontal transmission link 7 1 2 connected to the other end of the stitch pitch switching link 35 5 is pulled downward, and the first wrist 709a connected to the horizontal transmission link crank 709 of the horizontal transmission link 712 is Pull down to rotate in the clockwise direction. Therefore, the j point of the lower end of the second wrist 709b of the horizontal drive crank 709 is swung in the left direction and stopped. In this state, when the upper shaft 5 is rotated in the clockwise direction, the eccentric amount e of the horizontal transmission eccentric cam 70 1 causes the horizontal transmission drive lever 702 to reciprocate in a substantially horizontal direction, and thus is coupled to the second wrist of the horizontal transmission crank 709. The horizontal transmission rod link 707 of the 709b is centered on the j point of one end, and the horizontal transmission longitudinal rod 704 coupled to the other end I of the horizontal transmission rod link 707 is swung in the left-right direction. Further, the position at which the second wrist 709b of the horizontal drive crank 709 is swung in the left-right direction and stopped is set such that the j point of one end of the horizontal transmission lever link 707 coincides with the swing center position of the horizontal transmission longitudinal rod 704, even if the horizontal transmission is transmitted. The eccentric amount e of the eccentric cam 701 can still cause the swing center of the horizontal drive lever 707 to overlap with the swing center of the horizontal drive longitudinal rod 704, and the up-and-down motion transmitted to the horizontal drive longitudinal rod 704 becomes extremely small. Therefore, since the horizontal transmission amount of the transmission teeth 61 is also extremely small, the object to be sewn 21 is fed only slightly. That is, the amount of transmission of the minimum transmission pitch set by the -44-200827505 (42) by the stitch transmission adjusting lever 301 is formed. As described above, each setting of each of the sewn body transmission modes can be sequentially switched. <Setting example of the maximum stitch transmission pitch and the minimum inter-stitch transmission pitch >

Next, as shown in Fig. 8 (c), the 1 stitch pitch P 1 of the stitch drive is the maximum transmission, and the 1 stitch pitch P2 for the stitch drive is the minimum transmission according to the 2 4 (A), ( B) The diagram is explained below. As shown in Fig. 24(A), the stitch drive adjustment lever 301 is operated to the lowest point a'd of the maximum transmission pitch, respectively, and the inter-stack transmission adjustment lever 302 is set toward the uppermost point ad of the minimum transmission pitch. The position b' at which the action point of the stitch transmission adjustment lever 301 is formed is positioned at the uppermost point, and the position b at which the action point of the inter-stitch transmission adjustment lever 302 is formed is positioned at the lowest point. The adjustment lever link 3 07' coupled to the stitch drive adjustment lever 301 pushes up the other lateral arm end 310b of the reverse T-shaped transmission adjustment body 310, and is connected to the adjustment lever link of the inter-stitch transmission adjustment lever 302. 3 07 pulls down the lateral T-end 310a of the reverse T-shaped transmission adjustment body 3 10 . As a result, the reverse T-shaped transmission adjusting body 310 is rotated in the counterclockwise direction centering on the pivot point d pivotally supported by the wrist 311. > In its state, the longitudinal wrist end 310c of the inverse T-shaped transmission adjusting body 310 is inclined to the left, and the stitch pitch switching link 35 connected to the longitudinal wrist end 310c has its intermediate shaft 8 facing the clockwise The direction rotation causes the transmission switching cam 3 3 1 to eccentrically move, and the transmission switching lever 3 52 moves in the left direction position q -45-200827505 (43), and intermittently stops, the stitch spacing switch link 355 is at the end of the h point and The inverse T-shaped transmission adjustment body 310, which is rotated in the counterclockwise direction, coincides with the point c of the lateral lateral end 310a. That is, the stitch pitch switching link 3 5 5 —

The h point of the end is rotated clockwise around the joint pin 312 and moved to the lower left. Therefore, the horizontal transmission link 712 connected to the other end of the stitch pitch switching link 3 55 is pulled downward, and the first wrist 709a of the horizontal transmission link 709 connected to the horizontal transmission link 712 is downward. Pull down to rotate clockwise. Therefore, the j point of the lower end of the second wrist 709b of the horizontal drive crank 709 swings to the left and stops. In this state, when the upper shaft 5 is rotated in the clockwise direction, the eccentric amount e of the horizontal transmission eccentric cam 701 causes the horizontal transmission drive lever 702 to reciprocate in a substantially horizontal direction, and thus is coupled to the second of the horizontal transmission crank 709. The horizontal transmission lever link 707 of the wrist 709b has a j-point at one end as a swing center, and the horizontal transmission longitudinal rod 704 coupled to the other end I of the horizontal transmission lever link 707 swings in the left-right direction. Further, the position at which the second wrist 709b φ of the horizontal drive crank 709 is swung to the left direction is such that the j point of one end of the horizontal drive lever link 707 is set to coincide with the swing center position of the horizontal drive longitudinal rod 704, even if the horizontal transmission is transmitted. The eccentricity e of the eccentric cam 704 can still cause the center of oscillation of the horizontal transmission rod link 707 to overlap with the oscillating center of the horizontal transmission longitudinal rod 704, and thus the up-and-down motion transmitted by the horizontal transmission longitudinal rod 704 is extremely small. . Therefore, the horizontal transmission amount of the transmission teeth 610 is also extremely small, and only the slight feeding of the body 21 to be sewn is performed. That is, the amount of transmission of the minimum transmission pitch set by the inter-track transmission adjustment lever 320 is formed. On the other hand, as shown in Figure 2 4 (B), the inverse T-shaped transmission adjustment -46- 200827505 (44)

The longitudinal wrist end 310c of the body 310 is inclined to the left direction, and is coupled to the stitch pitch switching link 355 of the longitudinal wrist end 3 10c, and the intermediate shaft 8 is rotated toward the clockwise direction so that the transmission switching cam 3 35 is eccentrically moved. When the transmission switching lever 352 moves to the right direction position q' and intermittently stops, the stitch spacing switch link 5 5 5 end of the link and the reverse T-shaped direction of the reverse T-shaped transmission adjustment body 310 The c' point of the end 310b is identical. That is, the h point of the stitch pitch switching link 3 5 - 5 is rotated in the counterclockwise direction about the connecting pin 3 1 2 and moves to the upper right. Therefore, the horizontal transmission link 712 connected to the other end of the stitch pitch switching link 355 is pushed upward, and the first wrist 709a connected to the horizontal transmission link crank 709 of the horizontal transmission link 712 is pushed up. Rotate in the counterclockwise direction. Therefore, the j point of the lower end of the second wrist 709b of the horizontal drive crank 709 is swung in the right direction and stopped. In this state, when the upper shaft 5 is rotated in the clockwise direction, the eccentric amount e of the horizontal transmission eccentric cam 70 1 causes the horizontal transmission driving lever 702 to reciprocate in a substantially horizontal direction, so that the horizontal transmission eccentric cam 701 When the left eccentric rotational movement is performed, the other end I of the horizontal transmission lever link 707 is swung toward the lower left side by the horizontal transmission driving lever 702, and the horizontal transmission eccentric cam 70 1 is eccentrically rotated toward the right side, by The horizontal drive drive lever 702 causes the other end I of the horizontal transmission lever link 707 to swing upward toward the right to stop. As a result, the horizontal drive longitudinal rod 704 converts the reciprocating oscillating motion of the horizontal drive drive lever 702 into the maximum up and down direction of the reciprocating motion. Therefore, the transmission between the stitches set by the stitch transmission adjusting lever 301 is made to form the transmission amount of the maximum transmission pitch. -47- 200827505 (45) The above settings for each sewing machine drive mode can be switched in the same order as above. As described above, the respective transmission amounts of the 1-pitch pitch transmission and the 1-stitch pitch transmission according to the transmission amount setting mechanism 300 and the transmission mode switching mechanism 350 can be alternately switched by the respective adjustment levers 30 1

The position of the 3 0 2 sets the separately set transmission amount, and the transmission tooth 601 drives the sewn body 21, and the single-line interlocking seam is formed by the synergy of the crochet 13, the semi-rotating cylinder 200, and the linear traction action member 40 1 . Stitching. The stitch pitch and the stitch pitch can be set freely. Further, the above-described single-line interlocking hand stitch sewing machine is provided with a cover pin 1 4 which is detached from the line catching hook 1 3 a after the thread catching hook 13a of the crochet 13 catches the suture 20, in the crochet 1 3, the crochet/cover needle drive mechanism 100 that closes the line catching hook 13a during the period from the needle plate 1 2 to the top dead center of the crochet 13 and the period from the top dead center of the crochet 13 to the sewn body 21, However, the cover pin 14 may be driven by the crochet/cover needle driving mechanism 130 of the 25th (A), (B), and 26th drawings. In addition, in the 25th (A), (B), and 26th drawings, the same constituent elements as the crochet/cover pin driving mechanism 1A shown in the third (A), (B), and FIG. The same reference numerals are given and the description thereof is omitted. The crochet/cover needle driving mechanism 130 includes a cap driving link 132 having one end pivoted to the other end of the needle bar 11 and having a roller follower 134; the cap pin 15 is fixed to be horizontally movable The cover pin of the groove 1 3 8a of the fitting roller follower 1 3 4 drives the wrist 1 3 8; while the insert roller follower 1 3 4 moves from the top dead center of the crochet 13 to the bottom dead center in the vertical direction a vertical-48-200827505 (46) groove 135a that moves the roller follower 134 moving toward the bottom dead center in a horizontal direction at a predetermined position; and a plate groove cam formed with the horizontal groove 13 5b fixed to the arm 2 1 3 5.

One end of the cover needle drive link 132 is rotatably held by a pin 131a formed at the end of the needle bar clamp 131. The other end of the needle bar clamp 131 is formed with a crank lever pin 131b which is rotatably coupled to one end of the needle bar crank lever 103. The needle bar holder 131 is fixed to the needle bar 11 between the metal member 105 on the needle bar and the metal member 106 under the needle bar. Further, the other end of the cover needle drive link 132 is formed with a roller shaft 133' which is rotatably held by the roller 1 3 4 to constitute a roller follower 134. The cover pin drive wrist 1 3 8 is fixed on the cover pin bar metal piece 1 L3 and the cover pin bar lower metal piece 1 1 4 cover pin bar 15 . And the plate groove cam 1 3 5 is formed by connecting the vertical groove l35a and the horizontal groove 135b with a curved groove to form an L shape. The crochet/cover needle driving mechanism 130 of the above-described configuration is such that the line catching hook 13 a of the crochet 13 descends from the top dead center and penetrates the needle body 1 2 beyond the needle plate 1 2 and rises from the bottom dead center beyond the needle. When the plate 1 2 ' is released from the sewing body to the top dead center, the cover pin 1 4 a of the closing line catching hook 1 3 a can be driven. Specifically, when the rotating needle bar 11 of the upper shaft 5 is raised, the case is as follows. 25(A) shows that the roller follower 134 of the cover needle drive link 132 rises along the vertical groove 135 a of the plate groove cam 135 while raising the cover pin drive wrist 138. At this time, while the crochet 13 is raised, the cover pin 14 is also raised by the cover pin 15 that drives the wrist 1 3 8 by the cover needle bar. Therefore, as shown in Fig. 5(A) and Fig. 6(A) , the line of the pin 13 catches the full -49- 200827505 (47)

13a forms a closed state by the needle 14. In other words, the wire catching hook 13a of the crochet 13 descends from the top dead center through the body to be sewn, and rises beyond the needle plate 12 during the period beyond the needle plate 12, and the body to be sewn is separated to reach the top dead center. During this period, the line catching hook 1 3 a is formed to be closed by the cover pin 14 . Further, when the needle bar 11 is lowered by the rotation of the upper shaft 5, as shown in the 25th (B), the roller follower 134 of the cover pin drive link 132 is along the vertical groove 135a of the plate groove cam 135. After falling, it moves horizontally along the horizontal groove 13 5b. At this time, although the crochet 13 is lowered but the cover needle driving wrist 138 is stopped, as shown in Figs. 5(-B) and 6(B), the line catching hook .13_a of the crochet 13 is formed in an open state. That is, the line catching hook 13 3 a of the crochet 13 descends from the top dead center through the stitched body at the line catching hook 13 3 a of the crochet 13 , and after the needle plate 1 2 is opened, the line is caught from the cover pin 14 to catch the full line. 1 3 a 驱动 驱动 • • • • 盖 盖 盖 盖 盖 盖 盖 盖 盖 • • • • 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 , , , , , , , , , , , , , , , , , , , , , , , , , , At the same time, it is possible to prevent the captured line from being detached from the line catching hook 1 3 a. Further, in the above-described single-line interlocking hand stitch sewing machine, as shown in Figs. 1 8 (Μ) and ( Ν ), in the second stroke of the crochet 13, when the crochet 13 is lowered, the needle tip of the crochet 13 is sewn and sewn. The suture 20 caught by the thread catching hook 13 3 of the crochet 13 between the bodies 21 is loosened from the contracted state to loosen the thread, so that the suture 20 with the thread in a relaxed state is lowered to lower the crochet 13 The tip of the needle is inserted. Therefore, as shown in the 27th (A), (B), and 2nd (8th) and (B) drawings, when the crochet 13 is lowered from the top dead center in the second stroke -50-200827505 (48), The suture caught by the wire catching hook 13a is close to the wire mechanism 800 A and 800B between the needle tip of the crochet 13 and the object to be sewn. The wire mechanism 800A is represented by the figure of the brothers 27 (A) and (B), and has a hook-and-loop needle. An L-shaped wire guide 801 is formed between the tip of the lens 1 and the body 2 1 to be loosened; the trajectory is mounted on the horizontal plane of the upper shaft 5 to form an elliptical elliptical drive mechanism 802; and the elliptical drive is driven mechanism

The elliptical motion of 8 02 is communicated to the linkage 803 of the wire guide 801. The elliptical drive mechanism 802 is fixed in a state of being eccentric toward the upper shaft 5, and the cylindrical guide member driving cam 804 formed by the circumferential circumference of the cam groove 804a; the coverable cover wire driving cam 804 is connected with the connection The wire guide of the lever mechanism 803 drives the cylindrical wire guide driving body 80b formed by the wrist 805a; and the cam member incorporated in the wire guide driving body 805, which is fitted into the cam groove 804a of the wire guide driving cam 804 The mover 806 is constructed. The cam groove 804a of the wire guide driving cam 804 is formed such that the wire guide driving body 805 can linearly move in the same direction as the axial direction of the upper shaft 5. Further, the cam follower 806 is a roller shaft 806a which is fixed to the wire guide driving body 805 by a part protruding from the inner peripheral wall of the wire guide driving body 805; and is rotatably held at the front end of the roller shaft 806a. The roller 806b of the cam groove 804a of the wire guide driving cam 804 is embedded. The link mechanism 803 is: a wire guide driving wrist shaft 807 which is rotatably held in a shaft hole 805' of the wire guide driving wrist 805a of the wire guide driving body 805; the end is freely bent and coupled to the wire The driver guide shaft 808 at the front end of the drive shaft 8 07; the bolt is placed in the adjustment shaft of the wire guide -51 - 200827505 (49)

The other end of the other end of the 808 thread 8 08a is provided at the end of the wire guide mounting shaft 809 having the wire guide 801 at the other end; and the internal thread provided at a predetermined position of the arm 2 is provided (not The external thread 8 10a shown in the drawing is configured to be freely rotatably supported by the wire guide mounting shaft support 81 of the wire guide mounting shaft 809. Moreover, the external thread 808 of the wire guide adjusting shaft 80 8 and the internal thread 809a of the wire guide mounting shaft 809 are not fully tightened, so that the wire guide adjusting shaft 808 and the wire guide mounting shaft 809 are freely formed. turn around. Further, the internal thread provided at the predetermined position of the arm 2 and the external thread 810a of the wire guide mounting shaft support 810 are not fully tightened due to being bolted, so that the wire guide mounting shaft support 81 is freely formed with respect to the arm 2 turn around. The wire mechanism 800A constructed as above is shown in Fig. 29, and the front end portion 8 0 1 a of the wire guide 80 1 is wound around the metal pressing member 501 by the elliptical motion of the running locus 830 while the upper shaft 5 is rotated by 1. One week, the crochet 13 which does not interfere with the linear movement in the up and down direction can cause the front end portion 8〇1a of the wire guide 801 to perform an elliptical motion. Specifically, when the upper shaft 5 rotates, the wire guide driving cam 804 that is eccentrically fixed toward the upper shaft 5 is simultaneously rotated, thereby having a cam follower that is engaged with the cam groove 804a of the wire guide driving cam 804. The wire guide driving body 805 of the member 806 linearly reciprocates in the same direction as the axial direction of the upper shaft 5, and reciprocates in the eccentric direction of the wire guide driving cam 804 (hereinafter referred to as "eccentric reciprocating motion"). The linear reciprocating motion of the wire guide driver 805, once conveyed by the link mechanism 803, causes the wire guide driving wrist shaft 807 of the link mechanism 8〇3 to bend with the wire guide adjusting shaft 808, thereby causing a bending motion to the wire guide An-52-200827505 (50) The shaft bearing 810 is a fulcrum and a joint point of the wire guide driving wrist shaft 807 of the wire guide adjusting shaft 808 to form a force point for fixing to the wire guide mounting shaft 809.

The front end portion 801a of the wire guide 801 forms a point of action, so that the linear motion of the front end portion 801a of the wire guide 801 with respect to the wire guide driving body 805 is swung in the opposite direction. Further, when the eccentric reciprocating motion of the wire guide driving body 805 is transmitted by the link mechanism 803, since the wire guide driving wrist shaft 807 of the link mechanism 803 and the wire guide adjusting shaft 808 are not bent, the state is maintained, but The connecting point of the wire guide mounting shaft support 81 10 and the wire guide mounting shaft 809 is fulcrumly rotatably held by the wire guide driving wrist 807 of the wire guide driving wrist 805a of the wire guide driving body 805 to form a force point and fixed to the wire The front end portion 801a of the wire guide 801 of the device mounting shaft 809 forms a point of action, so that the front end portion 801a of the wire guide 80 1 swings in the opposite direction with respect to the eccentric reciprocating motion of the wire guide driving body 085. Therefore, once the two movements of the direction of movement of the wire guide driver 805 are orthogonal, the front end portion 801a of the wire guide 801 can perform the elliptical motion of the motion trajectory 830 in the horizontal plane, so that the crochet 13 in the second stroke When the top dead center is lowered, the thread caught by the wire catching hook 13a can be taken up by the leading end portion 801a of the wire guide 819 between the crochet 13 and the object to be sewn. Further, as shown in the 28th (A) and (B), the lead wire mechanism 800B includes an L-shaped wire guide 8 1 1 which is formed between the needle tip of the hook hook pin 13 and the object to be sewn 2 1 . An eccentric mechanism 8 1 2 that converts the rotational motion of the upper shaft 5 into an eccentric motion; a first link mechanism 8 1 3 that is coupled to the eccentric mechanism 8 1 2 to convert the eccentric motion of the eccentric mechanism into a horizontal motion; -53- 200827505 (51) The second link mechanism 814 that is connected to the eccentric mechanism 812 to convert the eccentric motion of the eccentric mechanism into the vertical movement; and the first link mechanism 813 and the second link mechanism 8 1 4 are combined to form the first The horizontal movement of the link mechanism 8 1 3 and the up and down movement of the second link mechanism 814 form an elliptical shape in the horizontal direction, and the elliptical motion is transmitted to the wire guide mounting wrist of the wire guide 801 8 1 5 〇

The eccentric mechanism 8 1 2 is used to drive the eccentric shaft 8 1 6 by a wire guide instead of connecting the third (A) and (B) drawings, and the fourth pin to the needle bar crank lever 103- of the crochet/cover pin driving mechanism 100. The crank lever pin 102 of the counterweight 101. The wire guide driving eccentric shaft 8 Λ6 is a crank pin 8 1 6 a that connects the needle bar crank lever 1〇3 to the counterweight 1 〇1, and a wrist to which the crank pin 8 16a is fixed at one end and the eccentric shaft 816c is fixed at the other end. The part 816b is composed of. The first link mechanism 8 1 3 is provided with a wire guide horizontal swinging wrist 817 having one end formed with a long hole 8 1 7a that is engaged with the eccentric shaft 8 1 6c of the wire guide driving eccentric shaft 8 16 . The long hole 817a is formed in the wire guide horizontally swinging wrist 817 such that its longitudinal direction forms an up and down direction. The wire swaying wrist 8 17 is formed by forming a long hole 817a at one end as a force point, and the other end is an action point, and a fulcrum is formed between one end and the other end. The wire supporting the wire guide horizontally swings the fulcrum of the wrist 8 1 7 The mechanism mounting table 8 1 8 is fixed to the arm 2. Forming the wire guide horizontally swinging wrist 8 1 The position of the fulcrum is rotatably supported by the wire guide fulcrum 8 1 9 provided at a predetermined position of the wire mechanism mounting table 8 1 8 . Therefore, the other end of the wire guide horizontally swinging wrist 8 1 7 is pivoted in the horizontal direction in the same direction as the direction of movement of the transmission teeth 6 〇1 with the wire guide shaft 8 1 9 as a fulcrum -54-200827505 (52) The second link mechanism 8 1 4 includes a wire guide upper and lower drive wrist 820 having a long hole 820a formed at one end and engaged with an eccentric shaft 816c of the wire drive eccentric shaft 816. The long hole 82 0a is formed on the wire guide to drive the wrist 820 up and down to make it longitudinally long

The direction is formed in a substantially horizontal direction. The wire guide 820 is formed by the upper and lower driving arms 820 forming a long hole 820a as a force point, and the other end is a working point, and a fulcrum is formed between one end and the other end. The fulcrum of the wire guide up and down driving wrist 820 is rotatably coupled to one end of the wire swaying wrist 8 17 by a coupling member 8 2 1 such as a coupling pin. Further, at the point of action of the wire guide up and down driving wrist 820, the upper end of the wire guide up and down swinging wrist 822 disposed in the vertical direction is rotatably coupled by a coupling member 823 such as a coupling pin. Therefore, the other connectable member 821 of the wire guide upper and lower drive arm 82G swings in the up and down direction as a fulcrum, so that the wire guide upper and lower swing arms 822 coupled to the other end of the wire guide drive wrist 820 can reciprocate in the up and down direction. The wire guide attaching wrists 8 1 5 are formed in a T-shaped direction in which the lateral wrists are arranged in a direction orthogonal to the transmission direction of the transmission teeth 601, and one of the lateral wrist ends 815a φ is rotatably connected by a coupling member 824 such as a coupling pin. At the other end of the wire guide horizontally swinging wrist 817, the other lateral arm end 815b is rotatably coupled to the lower end 822b of the wire guide up and down swinging arm 822 by a coupling member 825b such as a coupling pin. Further, the arrangement direction of the longitudinal wrist of the wire guide mounting wrist 815 is fixed to the front end 815c in the vertical direction wire guide 801. The wire mechanism 800B configured as described above is the same as the wire mechanism 800A. As shown in Fig. 29, during the rotation of the upper shaft 5, the front end portion 811a of the wire guide 8 is moved by the ellipse of the operation path 830 at the metal pressing member 501. The crochet 13 that is linearly moved for one week without interfering with the up and down direction may be -55-200827505 (53) The elliptical motion of the front end portion 811a of the wire guide 811. Specifically, when the counterweight 101 is rotated by the upper shaft 5, the distance between the axis of the crank lever pin 816a of the wire guide driving the eccentric shaft 816 and the axis of the eccentric shaft 816c is smaller than the rotation of the upper shaft 5 of the balance hammer 1 〇 The distance between the center and the center of the hole of the crank pin 8 16a that engages the wire guide driving the eccentric shaft 8 16 is short, so that the wire guide drives the eccentric shaft 8 1 6c of the eccentric shaft 8 16 to perform a circular motion.

The wire guide drives the eccentric shaft 816c of the eccentric shaft 816. When the circular motion is performed, the other end of the yarn guide horizontally swinging wrist 817 is supported by the long hole 817a, with the wire guide shaft 8 1 9 as a fulcrum and the transmission tooth 60 1 The direction of the transmission motion is oscillated back and forth in the horizontal direction of the same direction, so that the longitudinal wrist end 8 1 5 c of the wire guide mounting wrist 8 15 that is coupled to the other end of the wire swaying wrist 8 1 7 is also driven by the transmission tooth 601. The horizontal direction of the same direction of motion is reciprocated. Further, when the wire guide drives the eccentric shaft 8 1 6c of the eccentric shaft 8 16 to perform a circular motion, the other end of the wire guide upper and lower driving wrist 820 swings back and forth in the vertical direction by the long hole 820a with the coupling pin 821 as a fulcrum, and thus the connection The wire guide up and down swinging wrist 822 that drives the other end of the wrist 820 up and down in the wire guide is formed to reciprocate in the up and down direction. When the wire guide up and down swinging wrist 822 reciprocates in the up and down direction, the other end 815b of the wire guide mounting wrist 815 connected to the lower end 82 2b of the wire arm 8 is vertically oscillated in the up and down direction, so that the wire guide is attached to the wrist The longitudinal wrist end 815c of the 815 swings back and forth in a horizontal direction orthogonal to the direction of movement of the transmission teeth 601. Therefore, when the two reciprocating swings of the first link mechanism 8 1 3 and the second link mechanism 8 1 4 are combined, the tip end portion 8 1 1 a of the wire guide 8 1 1 can be horizontally -56-

200827505 (54) To perform the elliptical motion of the motion locus 830 as shown in Fig. 29, the front end of the wire guide 8 1 1 between the needle-point sewn bodies of the crochet 13 in the second stroke when the crochet 13 is lowered from the top dead center The part 8 1 1 a draws a line to capture the stitches captured by Weng to make the wire. Further, in the above-described single-line interlocking hand stitch sewing machine, when the hook penetrates the non-homogeneous body to be sewn or the extremely thick body to be sewn, there is a bend, so that the slanted collar of the semi-rotating cylinder 200 that rotates in a semi-rotation is rotated. When the suture 20 captured by the hook catching rod 13a is caught, a misalignment may occur in the direction in which the crochet 13 is separated from the horn collar 205a of the reel cylinder 200. Therefore, as shown in FIG. 30, 31 (8), and (B), the inner needle cylinder 241 is driven to rotate the inner needle cylinder 205 in a half rotation, and the inner needle cylinder drive 241 is provided with the crochet 13 after passing through the body to be sewn. Because the hook is pierced through the stitched body to correct the needle bearing at the wrong angle position. The inner syringe driver 203 and the needle holder 242 can be replaced by the half syringe 200 and the inner syringe driver 203. Usually, the sewing needle is sewn with a general sewing needle and a semi-rotating cylinder, and when the needle thread of the needle hole of the needle is taken by the horn of the needle cylinder, the stitch is formed in the needle forming coil and the horn of the needle is taken. Even if the crochet is less deviated from the wrong foot position, the jump stitch is not caused, but in order to prevent the slanting direction of the semi-rotating cylinder from colliding with the horn collar, the chamfered side of the wrong foot position of the wrist having the wrong angle is applied. Therefore, the inner syringe driver 241 provided with the needle holder 242 is provided with a curved wrong wrist 241a which is placed at the wrong leg of the crochet 13 when the sewn body passes through the second stroke, and prevents the crochet 13 from rotating toward the half. Therefore, with the 13 a needle at the semi-rotation angle of the 205a, there is a multi-needle inward crochet position on the line of the 13th 242 rotator, and the needle is bent in the direction of the horn of the needle -57-200827505 (55) 2 00 The horn collar 205a collides, and a chamfer 24 1 b is applied to the side of the wrong angle of the wrist 24 1 a.

However, in the above-described single-line interlocking stitch stitch forming method, the suture 20 captured by the thread catching hook 13a in the second stroke of the crochet 13 is taken by the horn collar 205a of the semi-rotating cylinder 200 of the semi-rotational forward rotation. At the time (Fig. 18(P)), since the stitching is not generated at the timing of the stitching 20, the jump of the crochet 13 causes a jump. Therefore, the needle holder 242 is bent to be fixed to a predetermined position of the inner cylinder driver 24 to form a substantially flat fj with the wrong wrist 241a. By this, the saturating needle 13 can be guided to the wrong position to prevent jump stitching. Further, the needle holder 242 is also chamfered 242a on the side of the wrong position of the crochet 13, so that the crochet 13 is bent in the direction in which the horn of the semi-rotating cylinder 200 is separated to prevent the occurrence of the jump. Further, in the above-described single-line interlocking hand stitch sewing machine, although the wire pulling action member 40 is provided such that the balance is reciprocated to give the stitch 20 loose or the stitch is wound, the transmission amount setting mechanism 300 is changed. The stitch spacing can also often form a certain amount of wire winding of the wire pulling action member 104. Therefore, as shown in Figs. 3 and 3, it is possible to provide a wire winding adjustment mechanism 420 that adjusts the thread winding amount of the wire pulling operation member 401 in accordance with the stitch pitch set by the gear amount setting mechanism 3A. The wire winding adjustment mechanism 420 fixes the wire pulling action member driving rod 423 to the end of the wire pulling action member driving rod table 405, and connects the wire drawing action member adjusting rod 424 to the other end of the wire pulling action member driving rod 423. The traction action member drives the wrist end 403a of the wrist 403 in place of the wire pulling action member driving lever 4〇4 constituting the element of the wire pulling drive mechanism 400. Specifically, the line pull -58- 200827505 (56)

The other end of the actuating member driving lever 423 and one end of the wire pulling action adjusting lever 424 are rotatably coupled by the connecting angle gyro shaft 422, and the other end of the wire pulling action adjusting lever 424 and the wire pulling action member drive the wrist 403 The wrist end 4 〇 3 a is rotatably connected by the step pin 4 1 4 . Further, the connecting angle gyro shaft 422 is rotatably fitted with a gyro 4 1 1 in a horizontal direction and a substantially rectangular parallelepiped shape, and a gyro 4 1 position above the linear traction actuator driving lever 423. Further, the joint angle gyro shaft 422 is formed such that the shaft protrudes from both sides with the flange as the center, and the angle gyro 4 2 1 can be separated from the wire pulling actuator-drive rod 423. The gyro 421 is slidably fitted in a horizontal direction to form a substantially rectangular parallelepiped linear traction actuator 425a formed on the lower surface of the wire rib 425. The 13-shaped groove 425a is also formed along the longitudinal direction. Further, a lateral wrist 426a of the T-shaped wire pulling action adjusting plate 426 is fixed to the upper surface of the wire pulling action adjusting bucket 425. The wire pulling action member adjusting φ of the fixed wire traction actuating member adjusting plate 426 is fixed to the wire pulling action adjusting plate table 428 fixed to the predetermined position of the bottom plate 3, and is fixedly fixed by being inserted in the vertical direction by the thrust bearing 429 The wire pulling action member adjusts the bucket shaft 427. Moreover, the hole 426c of the wire pulling action adjusting bucket shaft 427 through the wire pulling action adjusting plate 426 is fixed in the hole 425b of the wire pulling action adjusting bucket 425, and the adjusting platen 428 does not vibrate in the up and down direction with respect to the wire pulling action member. The ground is free to rotate and embedded. Further, since the wire pulling actuating member adjusting bucket 4 2 5 is placed in the state of the corner gyro 421, it is not disengaged from the wire pulling actuating member adjusting bucket shaft 427. -59- 200827505 (57)

Further, the longitudinal wrist end 426b of the wire pulling action adjusting plate 426 and the stitch transmission adjusting lever 310 are coupled to the adjusting wire 43 1 . The adjusting wire 431 is inserted, for example, into the wire guard 430, and the wire terminals 432 are fixed to both ends. One wire terminal 4 3 2 is fixed to the longitudinal wrist end 426b of the wire pulling action adjusting plate 4 2 6 , and the wire terminal 432 at the other end is fixed at a position and a fulcrum forming a force point of the stitch driving adjustment lever 310 Between locations. Further, the side of the wire 4 3 2 of the adjusting wire 4 3 1 is movably fixed to the wire pulling actuating plate 4 4 8 by the wire stopper 4 3 3 and the other wire terminal 432 side. The wire guide 433 is movably fixed to the arm 2 by a mounting plate 434. Further, a position of the stitch transmission adjusting lever 301 is fixed with a transmission adjusting lever knob 323. The line winding adjustment operation for the above-described line winding adjustment mechanism 420 will be described below based on Figs. 34(A) and (B). Figure 34 (A) is a view showing the wire winding adjustment mechanism 420 from the lower side of the sewing machine, respectively showing that the upper surface is wound by the thread winding adjustment mechanism 420, and the φ position is below. It is an occasion where the stitching is relaxed. Fig. 34(B) is a view showing the wire winding adjustment mechanism 420 from the lower side of the sewing machine, point a is the rotation center of the wire pulling action driving cam 407, point b is the rotation center of the cam follower 406, and point c is the line. The center of rotation of the traction actuating member adjusting bucket 425 and the point d are the center point of the connecting angle gyro shaft 422 of the connecting line traction actuating lever 423 and the wire pulling actuating lever 424, and the point e is the connecting line pulling action adjusting lever 424. The connection center point and the point f of the wire pulling action driving wrist 403 are the rotation center points of the wire pulling action driving wrist 403. Further, the length of L1 from the point a to the point d in the figure 3 (B) is -60 - 200827505 (58) ' is the maximum diameter CamR1 from the cam groove 407a plus the line pulling action member driving lever stage 405 The length of the cam follower 406 is fixed, the length fixed from the wire pulling actuating member driving lever 423, and the length of the length of the wire pulling actuating member adjusting lever 424, and L2 is L1 from the point a only when the angle of rotation is /3. The length from point a to point d', L2 = c〇S/3 xLl. The wire winding adjustment mechanism 420, when the adjusting wire 43 1 is wound up, is wound up the longitudinal wrist end 426b of the wire pulling action adjusting plate 426, so the wire pulling φ moving member adjusting hopper 425 adjusts the bucket shaft 427 with the wire pulling action member. In the 34th (A) and (B) diagrams, the rotation center is rotated in the clockwise direction so that the longitudinal direction can be aligned in the same direction as the longitudinal direction of the wire pulling actuating member driving lever 423. In this state, when the intermediate shaft 8 (Fig. 32, Fig. 33) is rotated, the wire pulling action member drives the lever table 405 such that the cam follower 406 corresponds to the cam groove 407a of the wire pulling action member driving cam 407. The shape causes the wire pulling action adjusting lever 424 to linearly reciprocate, so that the wire pulling action member 401 can be swung. At this time, the longitudinal direction of the wire pulling action adjusting bucket 42 5 φ is arranged in the same direction as the longitudinal direction of the wire pulling actuating member driving lever 423, so the wire pulling action member driving lever 4 2 3 and the wire pulling action member are adjusted. The rod 4 2 4 forms a linear reciprocating motion by the maximum moving distance in the square groove 425a of the linear traction action adjusting hopper 425 by the angle gyro 4 2 1 attached to the connecting angle gyro shaft 4 2 2 . Specifically, as shown in Fig. 3(B), the displacement amount η of the cam groove 407a of the driving cam 407 according to the wire pulling action member is formed by subtracting the maximum diameter CamR1 from the cam groove 407a.値 of the minimum diameter CamRs (H = CamRl-CamRs) 'The wire pulling action adjusting bucket 425 is equipped with -61- 200827505 (59) when placed in the same direction as the longitudinal direction of the wire pulling action driving lever 423, According to the displacement amount 凸轮 of the cam groove 407a, it can be transmitted to the wire pulling action adjusting lever 424 in its state to connect the wire pulling action adjusting lever 424.

The wire pulling action member drives the wrist 403 to swing. Therefore, the wrist end 403a of the wrist 403 can be driven by the length L1 swinging wire pulling action member, and thus can be fixed to the wire portion of the wire pulling action member 401 of the wire pulling action member swinging shaft 402 to which the wire pulling action member driving wrist 403 is fixed. The 401 swing reference position is the swing width of Np to form the largest Pa, and the stitch is wound. Moreover, the wire winding adjuster-structure 420 pushes the adjusting wrist wire 43 1 to push the longitudinal wrist end 426b of the wire pulling action piece caricature plate 426, so the wire pulling action adjusting bucket 425 can wire the pulling action piece The adjustment bucket shaft 427 is a rotation center, and is rotated in the counterclockwise direction in the drawing so that the longitudinal direction is inclined by only an angle of 0 with respect to the longitudinal direction of the linear traction actuator driving lever 423. In this state, when the intermediate shaft 8 rotates, the wire pulling action member driving the table 405 causes the cam follower shaft 406 to respond to the shape of the cam groove 407a of the wire pulling action member driving cam 407 to cause the wire pulling action member. The adjustment lever 4 2 4 linearly reciprocates, so that the wire pulling action member 401 can be swung. At this time, the longitudinal direction of the wire pulling action adjusting bucket 4 25 is disposed only at an oblique angle 0 with respect to the longitudinal direction of the wire pulling actuating lever 423, so the wire pulling action driving lever 423 and the wire pulling action are adjusted. The rod 424 is formed by the angle gyro 421 attached to the corner gyro shaft 422 to form an in-line traction actuator adjustment 425: the linear groove 425a is linearly reciprocated in an oblique direction. Specifically, as shown in Fig. 34 (B), when the wire pulling action adjusting bucket 425 is disposed at a position of only the tilt angle 0, the connecting wire pulls -62 - 200827505 (60) the actuating member driving lever 423 and the wire The center d point of the connecting angle gyro shaft 422 of the traction actuating member adjusting lever 424 slides in the groove 425a of the wire pulling action adjusting bucket 425 of the angle gyro 422, so that the d point forming the center point of the connecting angle gyro shaft 422 is moved to d 'point. As described above, once the d point forming the center point of the joint gyro shaft 4 2 2 is moved to the point d', the connected wire pulling action adjusting lever 424 is also simultaneously moved to decrease with the wire pulling action adjusting lever 424.

The movement amount 摆动 of the connected wire pulling action driving wrist 403 is reduced, so that the e point which forms the connection center point of the connecting wire pulling action adjusting lever 424 and the wire pulling action driving wrist-4-03 is only moved. Until e' point. Therefore, the amount of swing of the wire pulling action member 401 fixed to the wire pulling action member swinging shaft 402 to which the wire home driving member driving wrist 403 is fixed is reduced, and thus the wire portion 401a from the swing reference position Np to the wire pulling action member 40 1 is fixed. The swing width pa until now forms Pb, and the stitch can be relaxed. Further, in the 34th (A) and (B), the inclination direction of the wire pulling action adjusting bucket 425 is formed above, but is not limited thereto, and may be inclined downward as the setting of the wire winding adjusting mechanism 420 is set downward. The stitches are slack. Further, as shown in Fig. 34(B), the timing position of the minimum diameter CamRs of the cam groove 407a is the same point of forming and connecting the center point of the angle gyro shaft 422 with the rotation center of the wire pulling action adjusting bucket 425' However, the present invention is not limited thereto, and the center point of the connecting angle gyro shaft 422 of the connecting wire pulling action member driving lever 423 and the wire pulling action member adjusting lever 424 is adjusted at the timing of the minimum diameter CamRs of the cam groove 407a. The rotation center of the bucket 4M does not form the same point and can still operate normally. -63- 200827505 (61) Also, the above-mentioned single-line interlocking hand stitch sewing machine can only move the sewn body in a straight line. Therefore, as shown in the third (5) and (B) diagrams, the crochet 13 may be provided to descend from the top dead center through the body to be sewn, and the bottom dead center may be provided.

Before the detachment from the object to be sewn, the pressing and holding of the metal pressing member 501 that holds the object to be sewn on the needle plate 12 is released, and the driving direction of the object to be sewn is rotated by the crochet 13 as a turning axis. Linear drive switching mechanism 540. The above rotary operation transmission is called "free curve sewing". Free-form sewing Since the sewing machine can operate the direction of the sewing machine that is sewn in any direction, it is easy to form a small-swing curve with a certain stitch pitch and the pitch between the stitches. The slewing operation/linear drive switching mechanism 540 has a rotation motion of the upper shaft 5 to the pressing mechanism 500 as shown in the 35th (A), (B), and 36th, and the crochet 13 is sewed from the top dead center. The body is released from the bottom dead center before being detached from the body to be sewn, and the pressing of the metal pressing member 510 which is pressed and held by the sewing body on the needle plate 12 is released, and the crochet 13 is manually rotated by the slewing shaft. The release mechanism 520 is pressed. The pressing release mechanism 520 has a pressing release cam driving table 530 fixed to the other end side of the upper shaft 5, and a side surface side (left side in the drawing) of the pressing release cam driving table 530. The pressing release cam 528 is available on the upper shaft 5 The upper shaft 5 is slidably fitted. The pressing release cam 528 is a planar cam, and the concave portion 5 28a is formed on the circumferential surface by a body 528b formed by a pulley shape; one side surface (left side in the drawing) of the body 5 28b forms a high-order algebraic polynomial cam curve (Polydyne) The egg-shaped circular arc cam portion 528c of the curve; and the cylindrical portion 528d formed concentric with the center of rotation of the body 528b provided on the side surface (left side) -64-200827505 (62) of the circular arc cam portion 528c . Further, since the radius of the smallest diameter circular arc of the circular arc cam portion 528c is the same as the radius of the cylindrical portion 528d, the same surface is formed at the position. In order to prevent the pressing release cam 528 from rotating on the upper shaft 5, the fixed pin 529 is slidably fitted in a state of being protruded from the side (the left side in the figure) of the pressing release cam driving table 530 fixed to the upper shaft 5, and is formed to be slidably fitted. A pin hole 528e that conveys the rotational movement of the upper shaft 5.

Further, the pressing release mechanism 520 is movably fitted between the pressure bar 505 and the presser foot 502 of the pressing mechanism 500, and the pressing release plate 522 is movably fitted to the pressure bar 503. Between the pressing release plate 522 and the pressure bar holder 505, the pressing release spring 521 is fitted into the pressure bar 503, and the elastic force is applied to move the pressing release plate 522 downward. Further, the arm 2 transmits the rotational motion of the upper shaft 5 to the release mechanism 526 for the pressing mechanism 500, and the axial direction is formed in the horizontal direction. One end of the disengaging shaft 526 is fixed with an arc cam portion 528c that individually contacts the pressing release cam 528 and a pressing release cam arm 527 of the cylindrical portion 528d, and a pressing release wrist 523 is fixed to the other end. The wrist end 523a of the pressing release wrist 523 is coupled to the pressing release plate 522 by a connecting member such as a stepped screw that can swing freely. The above-described push release mechanism 520 switches the swing operation/linear actuator 540 for linear drive and manual swing operation transmission, and includes a switching lever 542 for switching the linear drive and the manual swing operation; and a recess 528a of the press release cam 528 is fitted, and A switching pin 546 that interlocks the switching operation of the switching lever 542; and a switching base 541 that is provided with the switching lever 542 and the switching pin 546 fixed to the arm 2. -65- 200827505 (63)

The switching base 541 is formed in a zigzag shape, for example, and the opposite two plate faces are fixed to the arm 2, and one hole 541a is provided on the plate surface in the vertical direction, and two circular arc shapes are arranged around the hole 541a. The long holes 541b and 541c are connected to the upper end of the hole 541a of the plate surface on the side opposite to the side on which the upper shaft 5 is disposed, and the one end 545a of the swing lever 545 is connected by a connecting member such as a step screw. The other end 545b of the shifting lever 545 is fixed to the switching pin 546 to constitute a pierceable long hole 541b. Further, the switching pin 546 limits the range of the swing by the swing of the shift lever 545 to the length of the long hole 541b in the longitudinal direction. An elongated hole 545c is formed between the one end 545a of the shifting lever 545 and the other end 545, and the long hole 545c is inserted into the switching shaft metal piece 544 fixed to the switching base 541 in the state of the insertion hole 541_a. The switching shaft metal member 544 is fixed to the switching lever 5 at one end, and the other end is rotatably inserted into the switching table 543 in which the two arms 543a and 543b are formed. Further, the switching lever 542 is disposed in the direction in which the shift lever 545 of the switching base 541 is provided. The arm 543a of the switching shaft 543 is swingably inserted into the long hole 541c of the switching base 541, and the range in which the one arm 543a swings by the rotation of the switching shaft 543 is limited to the length in the longitudinal direction of the long hole 541c. Further, the other arm 543b of the switching shaft 543 is fixed with a spring hook 549, and the spring hook 549 hooks one end of the switching spring 548, and the other end of the switching spring 548 hooks the switching pin 546. The switching spring 548 often imparts an elastic force to bring the spring hook 549 into close contact with the switching pin 546. The swing operation/linear drive switching mechanism 540 configured as described above is hooked on the other side of the switching shaft 543 that is tilted to the right side when the switching lever 542 is stopped at the position of the ground 3 5 (A) (in the drawing, in the left direction). The spring force of the switching spring 548 of the spring hook 549 of the arm 543 b - 66 - 200827505 (64), the switching pin 546 of the shift lever 545 moves the pressing release cam 528 toward the right side in the drawing, and thus the pressing release cam 528 and the pressing release The cam drive stage 53 0 is in contact. Further, when the switching lever 542 is stopped at the position of the 35th (B) diagram, the spring hook 549 of the other arm 543b of the switching shaft 543 which is tilted to the left side is cut.

By the elastic force of the spring 548, the switching pin 546 of the shift lever 545 moves the push release cam 528 toward the left side in the drawing, thereby isolating the press release cam 528 and the push release cam drive table 530. When the swing operation/linear drive switching mechanism 540 performs the free-form sewing, the switching lever 541 is rotated from the position of the 3 5 (A) to the counterclockwise direction (the left rotation direction) to the 3 5 (B). When the position of the figure is located above the position on the same surface as the cylindrical portion 528 d of the arcuate cam portion 528c of the pressing release cam 528, the arc cam portion 528c is moved in parallel to the pressing release cam arm 527. When the arm portion is in contact with the arm portion, the pressing release cam 528 cannot be moved. However, the other arm 543b of the switching shaft 543 can swing in the counterclockwise direction when the switching lever 542 is rotated in the counterclockwise direction. In this state, when the upper shaft 5 is rotated, the position on the same surface as the cylindrical portion 528d of the arcuate cam portion 528c of the pressing release cam 528 is rotationally moved to the arm portion of the pressing release cam arm 527, and thus the arc cam portion is formed. 52 8c can be moved in parallel on the arm cloth of the pressing release cam arm 27, and by the spring hook 549 of the other arm 5 43 b and the switching pin 546 of the shift lever 545 connected to the switching spring 548, the switching spring 548 is utilized. The spring force swings in the clockwise direction (turn right - 67-200827505 (65)). Specifically, when the other arm 543b of the switching shaft 543 swings in the counterclockwise direction with the switching shaft 543 as a center of rotation, the other arm 5 4 3 b faces from the center of rotation of the switching shaft 5 4 3 Moving in the left direction, the switching pin 546 is stretched by the elastic force of the switching spring 548, and the swinging center of the shifting lever 545 with respect to the switching base 54 is formed to swing toward the clockwise direction. The switching pin 546 is switched when it is swung clockwise

The push release cam 528 engaged with the pin 546 is moved from the position of the 35th (A) diagram to the position where the left ground 35 (B) is formed. When the pressing release cam 52 8 moves in the left direction, the arm portion of the pressing release cam arm 527 comes into contact with the circular arc cam portion 528c, and therefore the pressing release cam arm 527 is pressed in accordance with the cam shape of the circular cam portion 5 2 8c. The arm portion swings back and forth in the vertical direction with the release shaft 526 as a swing center. When the arm portion of the pressing release arm 527 swings back and forth in the vertical direction, the wrist end 523a of the pressing release wrist 523 also swings back and forth in the vertical direction. Therefore, the pressing release plate 522 coupled to the wrist end 523a can be released by the pressing release spring. The elastic force of 521 causes the metal pressing member 510 to move up and down (37(B), (C) 圔). Therefore, the crochet 13 is lowered from the top dead center through the body to be sewn, and the press of the metal press member 50 that presses and holds the body to be sewn on the needle plate 1 2 can be released before the bottom dead center rises and detaches from the body to be sewn. . Further, when the pressing release plate 5 22 is raised in accordance with the cam shape of the circular cam portion 528c, the elastic force of the pressing release spring 521 is stronger than the elastic force of the pressing adjustment spring 504, so that the pressure bar clamp 505 can be raised and released to be fixed to the pressure bar. The pressing of the metal pressing member 501 of 503 is maintained. Therefore, when the pressure adjusting screw 50 8 is loosely pushed, the elastic force of the pressing force adjusting springs 504 - 68 - 200827505 (66) is weakened, and the rising height of the metal pressing member 501 can be raised. Further, when the switching lever 542 set to the free-form sewing is rotated clockwise from the position of the 35th (B) and switched to the position of the 3rd 5th (a), the straight stitch can be performed. When the switching lever 5 42 rotates in the clockwise direction, the other arm 543b of the switching shaft 543 swings in the clockwise direction, so that the spring hook 594 of the other arm 5 4 3 b is coupled to the switching spring 548. The switching pin 54 6 of the lever 545 is elastically biased by the switching spring 548.

Swing toward the counterclockwise direction. Specifically, when the other arm 5 4 3 b of the switching shaft 543 swings clockwise with the switching shaft 543 as a center of rotation, the other arm 543b moves from the center of rotation of the switching shaft 543 toward the right. Therefore, the switching pin 546 is stretched by the elastic force of the switching spring 548, and is formed to swing in the counterclockwise direction with respect to the joint point of the switching base 541 of the shift lever 545 as the swing center. When the switching pin 5 46 is swung in the counterclockwise direction, the pressing release cam 528 engaged with the switching pin 546 moves from the position of the 35th (B) diagram toward the position of the right 35th (A). When the pressing release cam 528 is moved to the right, the arm portion of the pressing release cam arm 527 is separated from the circular cam portion 528c and contacts the cylindrical portion 528d. Therefore, the arm portion of the pressing release cam arm 527 is stopped at its position. status. Therefore, the metal pressing member 501 can be kept pressed (Fig. 37 (A)). Further, in the above-described single-line interlocking hand stitch sewing machine, in the first stroke of the crochet 13 3, the stitching pitch for the stitch stitching of the sewn body is transmitted by the driving tooth 601 and the metal pressing member 501, and the crochet In the second stroke of 1-3, the gear teeth 601 and the metal presser 501 are used to drive the stitches between the stitches of the stitched body, so that the needle cannot be arbitrarily changed -69-200827505 (67)

Track pitch transmission and distance between stitches. Therefore, as shown in FIGS. 38 and 41, when the crochet 13 is detached from the object to be sewn, the pressing and holding of the metal pressing member 501 can be released, and the transmission tooth 601 of the transmission-sewed body can be retracted and the needle can be arbitrarily given. The manual transmission/linear transmission switching mechanism 740 for the sewn body is manually driven while the track pitch transmission amount and the inter-stitch distance transmission amount. The above manual transmission is called "free motion sewing". In the free-motion sewing, the direction in which the body to be sewn is formed is a direction in which the sewing machine can operate arbitrarily. Therefore, it is possible to easily perform small-spinning sewing while arbitrarily changing the stitch pitch and the stitch pitch. The manual transmission/straight-line-transmission-switching mechanism 740 is shown in FIG. 38 and FIG. 3, and includes a transmission mechanism for transmitting the rotational motion of the upper shaft 5 to the pressing mechanism 500 and the feeding mechanism 600, and the crochet 13 When the detached body is detached, the press release mechanism 7 20A for manually displacing the sewn body and the crochet 13 are detached while the pressurization of the metal press member 501 is released, while the stitch pitch transmission amount and the inter-stitch pitch transmission amount are arbitrarily given. When the sewn body is disengaged, the transmission tooth 60 1 of the sewn body is manually reciprocated while the transmission teeth 60 1 of the transmission sewn body are retracted while the stitch pitch transmission amount and the inter-stitch distance transmission amount are arbitrarily given. The pressing release mechanism 720 has a disk-shaped pressing release cam driving table 73 0 fixed to the other end side of the upper shaft 5, and the pressing release cam 72 8 is slidable on the upper shaft 5 on the side surface side of the pressing release cam driving table 730. It is embedded in the upper shaft 5. The pressing release cam 728 is an eccentric cam, and the concave portion 728a is formed in a body 728b formed in the shape of a pulley in a circumferential surface; the side surface of the body 72 8b (left side in the drawing) and the rotation of the body 728b are -70- 200827505 (68) The cylindrical cam portion 7 2 8 c having a center of rotation at an eccentric position of the heart; and the side surface (left side in the figure) provided on the wheel portion 728c is concentric with the center of rotation of the body 728b than the cam portion 728c The cylindrical portion 728d has a diameter. Further, the cam portion 728c and the cylindrical portion 728d have positions on the same surface. In order to prevent the pressing release cam 728 from rotating on the upper shaft 5, a pin hole 728e in which the pin 729 fixed in a state protruding from the side surface (the left side in the drawing) of the pressing release cam driving table 730 is slidably fitted is formed.

Further, the pressing release mechanism 720A is placed in the same manner as the pressing release mechanism 520, and between the pressure bar holder 505 and the presser foot 502, and the pressing release plate 522 can be fitted to the pressure bar 505. Between the pressing release plate 522 and the pressure bar holder 505, the pressing release spring 521 is fitted into the pressure bar 503, and the elastic force is applied to move the pressing release plate 522 downward. Further, the arm 2 is provided with a release shaft 526 for transmitting the rotational motion of the upper shaft 5 to the pressing mechanism 500 so as to be horizontally formed in the axial direction. The release shaft 5 26 is provided on the arm 2 so that the shaft metal member 5 25 is freely rotatable. The cam portion 728c of the individual contact pressing release φ cam 728 and the double-fork 731 for releasing the pressing of the cylindrical portion 728d are fixed to one end of the release shaft 526, and the pressing release wrist 523 is fixed to the other end. The press release double fork 731 allows the upper arm 73 1a and the lower arm 731b to be movably fitted with the cam portion 728c of the press release cam 72 8 in a substantially contact state, thereby forming a space with respect to the cylindrical portion 72 8d. Further, the wrist end 523a of the pressing release wrist 523 is swingably coupled to the pressing release plate 522 by a connecting member such as a screw. The above-described pressing release mechanism 720A is provided with a switching lever 742 for switching linear transmission and manual transmission for switching the manual transmission/linear transmission switching mechanism 740 for linear transmission and means transmission; and a recess 728a for embedding the pressing release cam 200827505 (69) 728 At the same time, the switching pin 746 interlocking with the switching operation of the switching lever 742; and the switching lever 742 and the switching pin 746 are fixed to the arm 2

Switching base 741 of J.

The switching base 741 is formed in a zigzag shape, for example, and the opposite two plate faces are fixed to the arm 2, and one hole 741a is provided on the left side of the vertical plate surface, and two circular arc shapes are arranged around the hole 74 1 a. The long holes 74 1 b and 74 1 c are connected to the upper end of the hole 741a of the plate surface on the front side of the sewing machine, and the conversion rod 745 is swingably coupled to the connecting member such as a step screw. The other end 745b of the shift lever 745 is fixed with a switching pin 746 to form a pluggable long hole 74 1b. Further, the switching pin 746 limits the swing range to the length in the longitudinal direction of the long hole 741b by the swing of the shift lever 74 5 . An elongated hole 745c is formed between the one end 745a and the other end 745b of the shift lever 745, and the switching shaft metal member 744 of the switching base 741 is inserted into the long hole 745c with the insertion hole 741a inserted. The switching shaft metal member 744 has its end fixed to the switching lever 742, and the other end is rotatably inserted into the switching shaft 743 in which the two arms 743a and 743b are formed. Further, the switching lever 742 is disposed on the front side of the sewing machine provided with the shift lever 745 of the switching base 741. The arm 743a of the switching shaft 743 is swingably inserted into the long hole 741c of the switching base 741, and the range in which the one arm 743a swings by the rotation of the switching shaft 743 is limited to the long hole 74 1 c lengthwise. The length of the direction. A spring hook 749 is fixed to the other arm 743b of the switching shaft 743. The spring hook 749 hooks one end of the switching spring 748, and the other end of the switching spring 748 is hooked on the switching pin 746. The switching spring 748 is biased to bring the spring hook 749 into close contact with the switching pin 746. -72- 200827505 (70) The transmission tooth retracting mechanism 720B is fixed to the side surface side of the transmission retracting cam driving table 72 3 on the upper shaft 5 separated from the pressing release cam driving table 730 by only a predetermined length (Fig. Middle, right side) The drive tooth retracting cam 72 1 is slidably embedded in the upper shaft 5 on the upper shaft 5

. The transmission tooth retracting gear 721 is an eccentric cam, and the recessed portion 721a is formed in a body 721b formed on a circumferential surface such as a pulley shape; a side surface (right side in the drawing) provided on one side of the main body 721b, and an eccentric position of a rotation center of the main body 721b has The cylindrical cam portion 7 2 1 c of the center of rotation and the cylindrical portion 721d which is disposed on the side surface (the right side in the drawing) of the cam portion 7: 21c and which is concentric with the center of rotation of the body 721b and has a smaller diameter than the cam portion 721c . Further, since the radius of the cylindrical portion 72 1 d and the minimum radius of the cam portion 72 1 c are the same diameter, the cam portion 721c and the cylindrical portion 72 Id are positioned at the same plane. The transmission tooth retracting cam 72 1 is slidably fitted to the side surface (the right side in the figure) of the protruding transmission tooth retracting cam drive base 723 so as to be slidably engaged with the upper shaft 5 in the axial direction of the upper shaft 5 . The pin hole 721e of the φ pin 722 is fixed. Further, the transmission tooth retracting mechanism 72 0B uses the upper and lower transmission longitudinal rods 726 instead of the upper and lower transmission longitudinal rods 714 of the feed drive mechanism 7A. One end of the up-and-down transmission longitudinal rod 726 is formed with a rectangular hole 726a, and the cam portion 721c of the transmission tooth retracting cam 721 is movably fitted to the short side in a substantially contact state, and an upper portion thereof is formed with an elongated hole 726b for longitudinal rod guiding. The pin 7 25 is coupled to a longitudinal rod guide 724 that is fixed to the arm 2. Further, the cam portion 721c is fitted in the hole 726a so that the longitudinal direction of the hole 726a is formed in a horizontal direction, and a large space is formed in the horizontal direction. Therefore, the transmission tooth retracts -73- 200827505 (71) When the cam portion 721c that the cam 721 rotates forms an eccentric motion, the vertical movement longitudinal rod 726 does not move in the horizontal direction but moves in the up and down direction. Further, the long hole 726b is inserted into the longitudinal rod guide pin 725 such that the longitudinal direction of the long hole 726b forms a vertical direction, and a large space is generated in the vertical direction, so that the hole 726a of the up-and-down transmission longitudinal rod 726 retracts the cam of the cam 721 from the transmission tooth. When the portion 721c moves to the cylindrical portion 721d, the vertical transmission longitudinal rod 726 can be lowered.

The other end of the vertical transmission longitudinal rod 72 6 is rotatably coupled to the upper and lower transmission shaft driving wrist 715 fixed to the other of the upper and lower transmission shafts 613 by a coupling pin 716. Therefore, when the upper shaft 5 rotates, the cam portion 721c of the transmission tooth retracting cam 721 moves the one end of the upper and lower transmission longitudinal rods 726 up and down, so that the upper and lower transmission shaft driving wrists 715 can reciprocate the upper and lower transmission shafts 61. Further, the upper and lower transmission shafts 613 are fitted with a transmission tooth retracting spring 727 having a torsion coil spring, one of the wrists 727a is fixed to the bottom plate 3, and the other φ wrist 727b is hooked to the other end of the upper and lower transmission longitudinal rods 726. The upper and lower drive shafts drive the joint pins 7 1 5 of the wrists 7 1 5 to give an elastic force so that the joint pins 716 are constantly pressed downward. Therefore, when the hole 72 6a of the up-and-down transmission longitudinal rod 726 moves from the cam portion 721c of the transmission tooth retracting cam 721 to the cylindrical portion 721d, the transmission tooth retracting spring 727 causes the upper and lower transmission shaft to drive the coupling pin 7 1 5 of the wrist 7 1 5 The connecting end is often lowered downward, so that the upper and lower transmission longitudinal rods 726 can be stopped in the lowered state, and the position where the transmission teeth 601 are retracted can be stopped. Further, as the transmission tooth retracting mechanism 720B, one hole 74 1 d is provided on the right side of the plate surface located in the vertical direction of the switching base-74-200827505 (72) 74 1 to form the upper portion of the hole 741d of the plate surface on the front side of the sewing machine. The shift lever 750 swingably connects the one end 750a with a connecting member such as a step screw. The other end 750b of the shift lever 750 is fixed with a recess 721a embedded in the transmission tooth retracting cam 721.

The switching pin 751 is configured such that the shift lever 750 is swingable outside the switching base 741. An elongated hole 750c is formed between one end 750a of the shift lever 750 and the other end 75 0b, and a switching shaft metal member 752 fixed to the switching base 741 in a state of being inserted into the hole 741d is inserted into the long hole 750c. The switching shaft metal member 752 has one end rotatably inserted into the switching shaft 75 3 in which the two arms 753a and 753b are formed. Further, the two arms 753a and 75 3b of the switching shaft 753 are disposed in the same direction as the switching shaft 743 of the transmission/linear transmission switching mechanism 740. The switching shaft 7 5 3 - the square arm 75 3 a is disposed on the switching base 741 so as to be swingable outside the switching base 741. Further, a spring hook 754 is fixed to the other arm 753b of the switching shaft 75 3, and one end of the φ changing spring 75 5 is hooked on the spring hook 754, and the switching pin 751 is hooked at the other end of the switching spring 755. The switching spring 75 5 constantly imparts an elastic force to bring the spring hook 754 close to the switching pin 75 1 . Further, the spring hook 754 fixed to the other arm 75 3b of the switching shaft 753 and the spring hook 749 fixed to the other arm 743b of the switching shaft 743 are coupled by a connecting link 756. Further, the shape of the cam portion 728c of the press release cam 728 of the press release mechanism 720A is different from the shape of the arc cam portion 528c of the press release cam 528 of the press release mechanism 520 because the press release mechanism 720 A is sewn from the crochet 13 In the period in which the body 21 is detached, the pressing of the metal pressing member-75-200827505 (73) 501 is held, but the squeezing mechanism 520 is lowered from the top dead center through the object to be sewn 21, and is raised from the bottom dead center. During the period before the sewing body 2 1 is detached, the press holding of the metal pressing member 501 is released. The manual transmission/linear drive switching mechanism 740 constructed above is cut

When the lever 742 is stopped at the position of the ground 40 (A), the pressing release cam 72 8 comes into contact with the pressing release cam driving stage 73 0, and the transmission tooth retracting cam driving stage 72 3 is isolated from the transmission tooth retracting cam 72 1 . When the switching lever 742 is stopped at the position of the 40th (B) diagram, the pressing release cam 72 8 is isolated from the pressing release cam driving table 730, and the transmission tooth retracting cam driving table 723 and the transmission tooth retracting cam 721 are Form a contact. When the transmission/linear transmission switching mechanism 740 performs the free-action sewing by the means, the switching lever 742 is rotated from the position of the 40th (A) diagram to the counterclockwise direction (left rotation direction) to the 40th (B) diagram. position. At this time, when the position is the same as the position on the same surface as the cylindrical portion 728d of the cam portion 72 8c of the pressing release cam 72 8 , the cam portion φ 728c is parallelly moved to the upper portion of the double fork 731 for pressing release. At 731a, since the hook 731a is hooked on the upper portion, the pressing release cam 72 8 cannot move. However, the other arm 743b of the switching shaft 743 can swing in the counterclockwise direction when the switching lever 742 is rotated in the counterclockwise direction. When the upper shaft 5 is rotated in this state, the arm 73d can be rotated and moved to the upper portion of the pressing release double fork 731 at the same position as the cylindrical portion 728d of the cam portion 728c of the pressing release cam 728. Therefore, the cam portion 728c can be The arm 731a of the upper portion of the press release double fork 731 is moved in parallel, and the switch pin-76-200827505 (74) 746 of the change lever 745 connected to the spring hook 749 of the other arm 743b and the switching spring 748 is switched by the spring 748. The spring force swings in the clockwise direction (left direction of rotation).

Specifically, when the other arm 743b of the switching shaft 743 rotates in the counterclockwise direction with the switching shaft 743 as the center of rotation, the other arm 743b moves to the left from the rotation center of the switching shaft 743, so the switching pin 746 is The elastic force of the switching spring 748 is stretched to form a swinging center in the clockwise direction with respect to the joint point of the switching base 74 1 of the shift lever 745. When the switching pin 746 is swung in the clockwise direction, the pressing release cam 728 engaged with the switching pin 746 is moved from the position of the 40th (A) diagram to the position of the left 40th (B) diagram. When the pressing release cam 72 8 moves to the left, the pressing release cam 728 slides on the upper shaft 5 at the same radial point of the cylindrical portion 72 8d of the pressing release cam 728 and the cam portion 728c. Since the fork 731 is engaged with the cam portion 72 8c, the arm 731a of the upper portion of the pressing release double fork 731 is reciprocated in the vertical direction with the release shaft 536 as the swing center in accordance with the eccentric cam shape of the cam portion 72 8 c. When the arm 73 1a of the upper portion of the press release double fork 73 1 is reciprocated in the vertical direction, the wrist end 523a of the release wrist 523 is pressed and reciprocated in the vertical direction, so that the pressing release plate 5 22 coupled to the wrist end 523a can be pressed. The elastic force of the spring 521 is released to move the metal pressing member 501 up and down (Fig. 41(B), (C)). Further, when the switching lever 742 is rotated from the position of the 40th (A) diagram in the counterclockwise direction (the left rotation direction) to the position of the 40th (B)th diagram, the connection link 756 which is coupled to the spring hook 749 is also Stretched and moved to the left, so the spring hook attached to the other side of the connecting link 756-77-200827505 (75)

754 causes the other arm 753b of the switching shaft 75 3 to swing in the counterclockwise direction with the switching shaft 75 3 as the center of rotation. When the other arm 75 3b of the switching shaft 7 5 3 swings counterclockwise with the switching axis 75 3 as the center of rotation, the other arm 753b moves to the left from the center of rotation of the switching shaft 753, so the switching pin 754 is switched. The spring force of the spring 75 5 is stretched to form a swing center toward the clock direction with respect to the joint point of the switching base 74 1 with respect to the shift lever 75 0 . When the switching pin 754 swings in the clockwise direction, the transmission tooth retracting cam 721 engaged with the switching pin 754 moves from the position of the 40th (A) diagram to the position of the 4th 〇-(B) diagram which forms the left side. . When the transmission tooth retracting cam 721 moves to the left, the position of the hole 726a of the upper and lower longitudinal rods 726 of the transmission tooth retracting cam 721 moves from the cam portion 721c to the cylindrical portion 721d, so that the up-and-down transmission longitudinal rod 726 is stopped. In a state where the drive tooth retracting spring 727 is lowered, the drive tooth 601 is often stopped at the retracted position. Therefore, when the switching lever 742 is switched to the free-acting sewing, when the hook φ needle 13 is detached from the object to be sewn, the pressing and holding of the metal pressing member 501 can be released, and the transmission tooth 601 of the transmission-sewed body can be retracted. The sewn body is manually driven while arbitrarily imparting the stitch pitch transmission amount and the inter-stitch pitch transmission amount. Further, when the switching lever 742 set to the free-acting sewing is switched from the position of the 40th (B)th clockwise direction to the position of the 40th (A)th drawing, the straight stitching can be formed. When the switching lever 7 4 2 is rotated in the clockwise direction, since the other arm 743b of the switching shaft 743 is oscillated in the clockwise direction, the spring hook 749 of the other arm 743b and the switching spring 748 - 78 - 200827505 (76) The switching pin 74 6 of the connecting change lever 74 5 is swung in the counterclockwise direction by the elastic force of the switching spring 748. Specifically, the other side of the switching shaft 74 3

When the arm 743b swings in the clockwise direction with the switching shaft 743 as the center of rotation, the other arm 743b moves to the right from the rotation center of the switching shaft 743, so that the switching pin 746 is stretched by the elastic force of the switching spring 748. The joint point with respect to the switching base 741 of the shift lever 74 5 is formed to swing in the counterclockwise direction as the swing center. When the switching pin 746 swings in the counterclockwise direction, the pressing release cam 728 engaged with the switching pin 746 moves from the position of the 40th (B)th figure to the position of the right 40th (A) figure. When the press release cam 72 8 moves to the right, the arms 73 1a and 73 1b of the press release double fork 731 are separated from the cam portion 728c and contact the cylindrical portion 72 8d, so that the press release double fork 73 1 is formed therein. The state where the position is stopped. Therefore, the metal pressing member 501 can be kept pressed (Fig. 41 (A)). Further, when the switching lever 742 is rotated in the clockwise direction from the position of the 40th (B) diagram to the position of the 40th (A) diagram, the connecting link 75 6 connected to the spring hook 7 49 is moved to the right. The other spring hook 754 connected to the other link 756 causes the other arm 75 3b of the switching shaft 753 to swing in the clockwise direction with the switching shaft 753 as a center of rotation. When the other arm 753b of the switching shaft 75 3 swings in the clockwise direction with the switching shaft 75 3 as the center of rotation, the other arm 7 5 3b moves to the right from the rotation center of the switching shaft 753, so the switching pin 754 is The elastic force of the switching spring 755 is stretched to swing in the counterclockwise direction with respect to the connection point of the switching base 741 of the shift lever 75 0. When the switching pin 754 swings toward the counterclockwise direction, the switching pin -79-200827505 (77)

The 754-engaged transmission tooth retracting cam 721 is moved from the position of the 40th (B)th diagram to the position of the right 40th (A) diagram. At this time, when the cam portion 721c is placed in the upper side of the same position as the cylindrical portion 72 Id of the cam portion 721c of the transmission tooth retracting cam 72 1 , the cam portion 721 c is parallelly moved to the hole 726 a of the vertical transmission longitudinal rod 726, and is hooked. Around the hole 726a of the up-and-down transmission longitudinal rod 726, the transmission gear cam 721 is thus prevented from moving. However, the other arm 75 3b of the switching shaft 75 3 swings in the clockwise direction when the switching lever 742 rotates in the clockwise direction. When the upper shaft 5 rotates in this state, the position on the same surface as the cylindrical portion 721d of the cam portion 721c of the transmission tooth retracting cam 72 1 is rotationally moved to the hole 726a of the up-and-down transmission longitudinal rod 726, so that the cam portion 721c can be moved in parallel. To the hole 72 6a of the vertical transmission rod 726, the switching pin 751 of the shift lever 750 coupled to the switching spring 75 by the spring hook 754 of the other arm 753b is swung in the counterclockwise direction by the elastic force of the switching spring. Specifically, when the other arm 753b of the switching axis 753 swings in the clockwise direction with the switching axis φ 753 as the center of rotation, the other arm 7 5 3b moves from the center of rotation of the switching shaft 75 3 to the right. The switching pin 751 is stretched by the elastic force of the switching spring 75 5, and is swung in the counterclockwise direction with respect to the connection point of the switching base 741 of the shift lever 750 as the swing center. When the switching pin 7 51 swings in the counterclockwise direction, the transmission tooth retracting cam 721 engaged with the switching pin 751 moves from the position of the 40th (B)th diagram to the position of the 40th (A)th drawing which is right. When the transmission retracting cam 721 moves to the right, the wall surface of the hole 72 6a of the up-and-down transmission longitudinal rod 726 contacts the cam portion 721c, and thus the upper and lower transmissions are made according to the eccentric cam-80-200827505 (78) of the cam portion 721c. The longitudinal rod 726 swings back and forth in the up and down direction. When the vertical rod 726 is moved up and down, the upper and lower drive shaft driving arms 715 can reciprocate the upper and lower drive shafts 613. Due to the reciprocal rotation of the upper and lower drive shafts 613, the upper and lower drive double forks 616 are oscillated back and forth, and the upper and lower drive rollers 608, which are fitted to the upper and lower drive double forks 616, reciprocate the other end of the drive base 612 in the up and down direction. As described above, the transmission tooth retracting mechanism 720B reciprocates the other end of the transmission base 602 in the up and down direction, and simultaneously moves the transmission-tomb 602 in the horizontal direction with the horizontal transmission shaft 601 and the horizontal transmission wrist 604, and is fixed at The drive teeth 601 of the drive base 602 can perform a four-step motion of the drive such as ascending-forward-down-reverse-reverse. Therefore, in the case where the switching lever 7 4 2 is switched to the linear drive, straight stitching can be formed. Further, the press release mechanism 702A and the drive retracting mechanism 72A can be freely sewn even if used alone. When only the release mechanism 7 2 0 A is pressed, when the crochet 1 3 is detached from the object to be sewn, the press-fitting of the metal press member 5 0 1 is released, and the stitch pitch transmission amount and the inter-stitch distance transmission amount are arbitrarily given while manually The drive is sewn. Further, when only the tooth retracting mechanism 7 2 0B is driven, the pressing force adjusting screw 5 〇 8 is set to reduce the pressing force of the metal pressing member 501, and when the crochet 13 is detached from the object to be sewn, the driving body is sewn. The transmission teeth 60 1 are retracted while arbitrarily imparting the stitch pitch transmission amount and the inter-stitch pitch transmission amount to the manual transmission of the sewn body. Further, in the above-described single-line interlocking hand stitch sewing machine, when the thick thread or the stitch having little twist is sewn, there is a possibility that the thread catcher 13a of the crochet hook 3 cannot catch the stitch. Therefore, as shown in Fig. 42 and Fig. 43, -81. 200827505 (79) may be provided to be drawn from the wire outlet 212a of the semi-rotating cylinder 200, and positioned by the wire pulling action member 401 to the wire trap 13a. The wire that is connected to the crochet 13 is forcibly inserted into the wire card drive mechanism 450 of the wire insert 451 of the hook catching hook 13a. Further, the front end 451a of the wire insert 45 1 is a concave portion formed in the concave portion to hook the suture, and reciprocates under the needle plate 12.

The wire insert driving mechanism 450 is a wire pulling action driving cam 407 which is used by the wire pulling drive mechanism 400, and a wire insert driving cam groove 456 which forms an end face cam for the rocking wire insert 45 1 on the upper surface of the wire pulling action driving cam 407. Further, a cam groove 407a for the oscillating linear traction actuator 401 is formed below the linear traction actuator driving cam 407. Further, the wire insert driving mechanism 450 includes a cam follower 455 having a wire insert driving cam groove 456 that is engaged with the wire pulling action driving cam 407 at one end 45 2a in the horizontal direction, and the other end 45 2b is fixed. The wire card of the cable plug 451 drives the wrist 452, and the wire card driving wrist 452 is rotatably mounted to the wire card driving wrist 453 of the bottom plate 3. The cam follower 455 is a roller shaft 452c provided with one end 452a of the spool driver 452, and is rotatably held at the front end of the roller shaft 452c, and the wire insert driving the cam groove 456 embedded in the wire pulling action driving cam 407 The roller 457 is constructed. And the online plug-in driving wristband 453 fixed driving wrist shaft 454'. The driving wrist shaft 454 is rotatably mounted with a wire insert driving wrist 452 ° or more. The wire plug driving mechanism 4 50 is a wire plug driving wrist 4 5 2 to drive The wrist shaft 4 5 4 is a fulcrum, so that the cam follower 4 5 5 forms a point of action, the wire insert 45 1 forms a force point, and the cam follower 45 5 draws a corresponding line -82 - 200827505 (80) The workpiece drive cam 407 The shape of the wire insert driving cam 456 causes the wire insert driving arm 452 to rotate. Therefore, the front end 451a of the wire insert 451 penetrates the shackle 13 and is placed on the needle body of the needle plate 12, and can be lifted during the rise from the bottom dead center. The side of the rotating cylinder 200 is reciprocated. Further, the above-mentioned single-line interlocking hand stitch sewing machine is wound around the other end of the inner cylinder driver 2〇3 and the inner needle cylinder formed in the inner cylinder driver spring 204 in the second stroke of the crochet 13 The suture 20 of the gap 0 2 between 205 is moved from the wound state to the relaxed state by the half-rotation normal rotation of the inner needle cylinder 205 as shown in the first 8 (U) diagram. Therefore, a portion around the inner barrel 2〇5 of the semi-rotating cylinder 200 can be provided with a suture which is extracted from the horn 205a of the inner cylinder 205 and released from the thread catcher 13a of the crochet 13 The rotation of the inner needle barrel 205 is wound around the semi-rotating cylinder 200 and staggered after the stitches wound around the semi-rotating cylinder 200, and is wound in half before the line unwound from the semi-rotating cylinder 200 is wound up. The suture of the rotating needle cylinder _2 〇 0 is temporarily retained, and the threaded wire is wound by the thread pulling actuating member 40 1 to wind the stitches wound by the semi-rotating cylinder φ 200 to release the temporarily retained concave line retaining portion 205f (45th) Fig.), or a convex line retention portion 205g (Fig. 46). The inner cylinder 205 having the concave line retention portion 205f and the convex line retention portion 205g is shown in Fig. 45 and Fig. 46, and is a semi-rotating cylinder formed in a semicircular shape to form a shofar on one end side in the rotational direction. An upper claw 20 5d and a lower claw 20 5e are formed in the vicinity of the collar 205a at the same time as the lead portion 205c, and a gap formed by the upper claw 205d and the lower claw 205e forms a wrong foot groove 205h. The concave line retention portion 205f is formed as shown in Fig. 45, and is formed on the opposite side surface on the side of the wrong foot groove 2〇5h formed with the circular arc-shaped lower claw 2〇5e, and can be played as -83-200827505 (81 The above line retention function. Further, the convex line staying portion 205g is formed as shown in Fig. 46, and is formed to protrude from the side opposite to the side of the wrong-foot groove 20 5h of the circular-arc-shaped upper claw 205d, thereby exhibiting the above-described line retention function.

The concave line retention portion 205f and the convex line retention portion 205g configured as described above are formed at the position of the half rotation of the inner needle cylinder 205 as shown in Fig. 18(U), as shown in Fig. 47. The state in which the thread is hooked is maintained, so that the suture threaded into the semi-rotating cylinder 200 can be temporarily retained, and then the suture thread which the semi-rotating cylinder 200 passes out can be wound by the thread pulling action member 401 to unwind the seam. Temporary stranding of the line. Therefore, in the second stroke of the hook detector 1, the suture which penetrates the gap 〇2 formed between the other end of the inner syringe driver 203 to which the inner syringe driver spring 204 is fixed and the inner syringe 205 is penetrated even if half The rotary forward rotation inner cylinder 205 can still maintain the tightening state, and does not loosen the suture 20 that penetrates the semi-rotating cylinder 200 and the suture 20 led out from the wire outlet 212a, and can wire the lead portion 401a of the actuating member 401. Capture. Further, one of the concave line retention portion 205f and the convex line retention portion 205g may be provided. Next, the single-line interlocking hand stitch forming method is used as a center to appropriately select the above-mentioned cover pin driving mechanism 130, the wire mechanism 800A, 800B, the needle bearing member 242, the wire winding adjustment mechanism 420, and the rotary operation/linear drive switching. The mechanism 540, the manual transmission/linear drive switching mechanism 740, the wire insert drive mechanism 450, the concave line retention portion 2 0 5 f, and the inner needle barrel 205 of the convex line retention portion 205g are assembled into a single-line interlocking seam.

Further, the eighteenth (A) to (W) drawings are the same as those of the above-described single-line interlocking hand stitching sewing machine, and the description thereof is omitted. Further, the overall perspective view shown in Fig. 4 is the overall perspective view shown in Fig. 1 and the shape of the parts used by the feed drive mechanism 700, the transmission amount setting mechanism 300, and the transmission mode switching mechanism 350. However, the configuration of the semi-rotating cylinder 200, the pressing mechanism 500, the feeding mechanism 600, and the linear traction drive mechanism 400, which have the same configuration and operation, are the same, and the inner cylinder 205 is excluded. The actions are the same, and therefore the same reference numerals are given to omit the description. Further, the single-line interlocking hand stitching sewing machine for the free-form sewing uses a turning operation/linear driving switching mechanism 540 having a wire mechanism 800A and a pressing release mechanism 520. Further, in the overall perspective view of the first chart chamber, the syringe driving mechanism gear 230 is engaged under the syringe driving mechanism 224, but in the overall perspective view shown in FIG. The syringe drive mechanism 220 is engaged under the syringe shaft gear 224 to constitute a syringe drive sector gear 233. The above-described syringe driving mechanism 220 is a good-looking gear which is disposed at a position of the bottom plate 3 which is disposed below the nipper shaft gear 224, as shown in Fig. 50, 51-85-200827505 (83) ,, using the syringe driving sector gear 233. The shaft 235 is substituted for the sector gear shaft 221 of the cylinder drive mechanism 22 0 shown in Figs. 14 and 15 . Therefore, the cylinder driving longitudinal rod 22 8 shown in Figs. 50 and 51 is formed shorter than the cylinder driving longitudinal rod 228 shown in Fig. 14 and Fig. 15.

Further, a transmission adjustment lever knob 323 is attached at a position where the stitching adjustment lever 3 0 1 and the inter-stitch transmission adjustment lever 302 are formed. In Fig. 48 and Fig. 49, when the driven pulley 4 driven by the motor belt via the drive belt MB is rotated from the crochet 13 side toward the clockwise direction, the upper shaft 5 is rotated to drive the crochet and cover needle drive. The mechanism 130, the feed drive mechanism 700, the syringe drive mechanism 220, the wire traction drive mechanism 400, the swing operation/linear drive switching mechanism 540, the wire mechanism 800A, and the wire card drive mechanism 450 are driven. When the crochet/cover needle driving mechanism 130 is driven, the crochet 13 is linearly reciprocated in the vertical direction, and the feeding mechanism 6 0 0 drives the four-step movement of the driving gear 6 0 1 by the feeding mechanism 6 〇0. When the cartridge driving mechanism 220 is driven, the inner cylinder 206 of the semi-rotating cylinder 200 is rotated half-rotation forward and half-rotated, and the linear traction driving mechanism 400 drives the swinging wire pulling action member 104, and the swing operation/linear transmission switching mechanism 5 At the time of the 40-drive, the first and second strokes of the crochet 13 are released from the pressing of the metal pressing member 501 only for a predetermined time, and the wire guide 801 is placed on the first stroke and the second stroke of the crochet 13 during the driving of the wire mechanism 800A. Elliptical motion is performed in the vicinity of the crochet 13, and the wire inserts 45 1 -86 - 200827505 (84) are reciprocated for each of the first stroke and the second stroke of the crochet 13 when the wire insert driving mechanism 450 is driven. In addition, the description of the operation of each mechanism is omitted in the above description of the configuration.

The above-described action of the crochet 13, the semi-rotating cylinder 200, the wire pulling action 401, the transmission tooth 601, the metal pressing member 501, the wire pulling action member 401, and the wire insert 451 are synergistic as follows, with one stitch 20 Hand stitch stitches are formed on the surface of the body 21 to be sewn, and interlock stitch stitches are formed on the inner surface. Further, in the case of linear transmission, the same sewing operation as that of the above-described single-line interlocking hand stitch sewing machine (Figs. 1 and 2) is omitted, and the description thereof is omitted. Switching the switching lever 542 to the swing operation transmission (free-curve sewing) When the sewing machine is driven, (a) the crochet 13 that reciprocates linearly in the vertical direction descends from the top dead center (upper axis 5: 0 degrees) in the first stroke. When the body 21 to be placed on the needle plate 12 (Fig. 18(A) to Fig. 18(F), Fig. 52(A)) is raised from the bottom dead center (upper axis 5: 180 degrees), The line catching hook 13a φ captures the thread 20 of the semi-rotating cylinder 200, which is reversed by the lower half of the needle plate 12, and is led out by the wire pulling action member 401, and is circumferentially connected to the stitching 20 of the crochet 13 (18th ( G), 18 (H), and 52 (A)). At this time, the half-rotating cylinder 200 has the bobbin case 212 of the bobbin case 212 as shown in Fig. 44 (a), and the crochet 13 is disposed to reversing the inner barrel 205 of the semi-rotating cylinder 200 when it is lifted from the needle plate 12. From the direction and position in which the needle plate 12 is separated. Thereby, the suture 20 derived from the wire pulling action member 401 can be attached to the crochet 13 in the circumferential direction. Further, while the wire pulling action member 4 〇1 is taken out from the wire exit 2 1 2 a of the bobbin case 2 1 2, the wire catching hook 13a of the crochet-87-200827505 (85) 13 is positioned, and the crochet 13 is circumferentially attached. The wound suture 20 is forcibly inserted into the thread catching hook 13a of the crochet 13 by the swing of the thread insert 451 (18th (F) to 18th (K), 44th, 52nd (B)). Further, the crochet 13 is rotated substantially from the top dead center (upper axis 5: 0 degrees) to the lower dead point (upper axis 5: 180 degrees) to stop the semi-rotating cylinder 200. Since the rotation stop semi-rotating cylinder 200 is hooked to the thread catching hook 13a of the crochet 13 in the first stroke, the cylinder in which the half rotation φ is rotated in the second stroke is reversed by half rotation. opportunity. In addition, the crochet 13 in the first stroke of the crochet 13 is lowered from the top dead center to the sewn body 2, and is released from the needle body 1 2 before being lifted from the bottom dead center 21 to release the sewn body. The pressing of the metal pressing member 5 0 1 of 2 1 is held (1st (8th) to 18th (th), and 52nd (B)). Thereby, in the first stroke of the crochet 13, the crochet 13 can be manually rotated as the rotary shaft to operate the direction of the driven body 2 1 . Further, the semi-rotating cylinder 200 starts the half rotation reversal after the crochet 13 is inserted into the sewn body 21% (upper axis 5: 13 0 degrees) (the first 8 ( Ε ) map, the 5 2 (A) map). The wire pulling action member 401 is stopped at the most advanced position (the upper shaft 5 · · 8 degrees) before the crochet is inserted into the body 21 (Fig. 18 (D), Fig. 5 2 (A)). The cover pin 14 is opened when the crochet 13 is inserted into the body 21 to be sewn (Fig. 8 (E), Fig. 5 2 (A)). The driven tooth 60 1 stops the feeding of the sewn body 2 1 before the crochet 13 is inserted into the object to be sewn 2 i (Fig. 18(D), Fig. 52(A)). (b) The crochet 13 is sewn from the sewn body 21 in the first stroke and passes through the top dead center (upper shaft 5: 366 degrees), and the sewn body is driven by the transmission teeth 601 - 88 - 200827505 (86). At the same time as the 1-stitch pitch transmission of 2-1, the crochet 13 of the catching suture 20 is raised and the semi-rotating cylinder 200 is reversed and the thread is wound up (18(1) to 18(M), 52 (A) map). Furthermore, the semi-rotating cylinder stops the semi-rotation reversal after the saturation needle 13 passes the top dead center (upper axis 5: 360 degrees) (upper axis 5: 367 degrees) (18th (Μ), 5 2 (A) Figure). Line traction action piece 4 01 reaches the next death

When the point (upper axis 5 ·· 1 80 degrees) starts to swing backwards, the suture 20 can be sent out (Fig. 18(F), Fig. 52(A)), and the crochet 13 passes the top dead center (upper axis 5: 3 60 degrees) 1T stops and retreats (1st 8th (L), 52nd (A)). When the crochet 13 moves from the bottom dead center (upper axis 5: 180 degrees) to the top dead center (upper axis 5: 366 degrees), the burr 13 passes through the needle plate 12 and then catches the hook 1 3 a In the closed state, the object to be sewn 2 1 and the crochet 1 3 pass together (Fig. 18 (J), Fig. 18 (K), Fig. 52 (A)). The drive tooth 601 starts the 1-stitch pitch transmission before the crochet 13 passes the top dead center (upper axis 5 ··3 60 degrees) (the 1 8 (L) map, the 5 2 (A) map). Further, in the first stroke of the crochet 13, the thread guide 801 causes the front end portion 80 1a to perform the elliptical motion of the motion locus 83 0 shown in Fig. 29 to perform only one rotation in the horizontal direction (the first S (A) map ~ In the first 8 ( Μ ) map and the 5 2 (A) diagram, the crochet 13 does not catch the suture 20 even if the descending line catches the hook 13a. (c) The crochet 13 descends from the top dead center (upper axis 5: 3 60 degrees) through the object to be sewn 21 in the second stroke (18th (N), 18th (0)th, 52nd (A)) When the bottom dead center (upper axis 5: 540 degrees) rises, the slanted collar 205a of the semi-rotating cylinder 200 that rotates in a semi-rotation direction takes the line -89 - 200827505 (87) The stitch caught by the catch hook 13a At the same time, the captured suture 20 is released from the line catching hook 13 3 by the rotation of the semi-rotating cylinder 200 (Fig. 18(P), Fig. 52(A)). Furthermore, the crochet 13 is substantially stopped from the top dead center (upper axis 5: 3 60 degrees) to the bottom dead center (upper axis 5: 54 degrees).

Rotate the syringe 20 0. The above-described rotation of the semi-rotating cylinder 200 is performed in order to open the suture 20 of the thread catching hook 13 a of the crochet 13 in the second stroke, and the horn 205a of the cylinder is opened from the thread catching hook 13a. In the first stroke, the cylinder in which the half rotation is reversed is rotated at a half rotation. Further, the semi-rotating cylinder 200 starts the semi-rotation forward rotation when the crochet 13 reaches the bottom dead center (upper axis 5 ··5 40 degrees) (Fig. 18 (P), Fig. 52 (A)). The wire pulling action member 401 is stopped before the crochet 13 is inserted into the body to be sewn 21 (Fig. 18 (N), Fig. 52 (A)). Subsequently, when the burr 14 is lowered from the top dead center through the body 21 to be sewn, the thread catching hook 13a of the crochet 13 is opened (Fig. 18(0), Fig. 52(A)). The transmission tooth 60 1 stops the 1 stitch pitch transmission before the crochet 13 is inserted into the body 21 to be sewn (Fig. 18 (N), Fig. 52 (A). Fig.). Further, in the second stroke of the crochet 13, the distal end portion 801a of the thread guide 801 performs only one rotation in the horizontal direction of the elliptical motion of the motion locus 83 0 as shown in Fig. 29 (18th (M) to 18th (W) Figure, Figure 52 (A)). At this time, when the crochet 13 is lowered, the suture 20 caught by the thread catching hook 13 a of the crochet 13 between the needle tip of the crochet 13 and the body to be sewn 2 can be loosened from the contracted state. Therefore, the wire is loosened between the needle tip of the crochet 13 and the body 21 to be sewn toward the non-opening direction of the wire catching hook 13 a with the leading end portion 801a of the wire guide 801 (No. -90-200827505 (88) ) 18 ( Μ) , (Ν), and 52 (B)). Specifically, as shown in Fig. 29, the elliptical motion of the motion locus 830 of the front end portion 8a of the wire guide 801 is a clockwise direction when the metal pressing member 501 is displayed from above, and can be at the position of the wire point at which the motion track 83 0 is formed. In the vicinity of 83 0a, the thread of the suture 20 is caught in the non-opening direction of the hook 13a, and the leading end portion 8 0 1 a of the wire guide 801 is hooked by the leading end portion 8〇1 & Further, the position 830b of the motion locus 803 shown in Fig. 52 (:6) is the position shown in Fig. 29, and the crochet 13 in the second stroke of the crochet 13 descends from the top dead center through the sewn body. 2, the pressing of the metal presser 501 that holds the object to be sewn 21 on the needle plate 12 is released (the 18th (P) to the 18th (T)) Figure, Figure 52 (B)). Thereby, in the first stroke of the crochet 13, the direction of the movement of the body 21 to be sewn can be manually rotated by the crochet 13 as a rotary axis.

In the case where the inner cylinder 205 of the semi-rotating cylinder 200 includes, for example, a convex line retention portion 205g, even if the semi-rotation forward rotation of the inner cylinder 205 shown in Fig. 18(U) is formed, as in the 47th The figure shows a state in which the thread retaining portion 205g which can maintain the convex shape is hooked with the suture 20, so that the suture threading into the semi-rotating cylinder 200 can be temporarily retained, and then the wire pulling action member 04 is wound up from the half rotation. The suture threaded through the syringe 200 can release the temporary retention of the suture. Therefore, in the second stroke of the crochet 13, the suture 20 which is formed in the gap .02 formed between the other end of the inner syringe driver 203 to which the inner syringe driver spring 204 is fixed and the inner syringe 205 is inserted. The syringe 205 can still be kept in a tight state when it is rotated halfway. 200827505 (89) In the second stroke of the crochet 1 3, the thread insert 45 i (the 18th (th) to the 18th (S) and 52 (B)) is also oscillated, and the stitch 20 is It is not positioned on the line catching hook 13a of the crochet 13. (d) The suture 20 released by the horn collar 205a of the semi-rotating cylinder 200 is further rotatably inserted through the semi-rotating cylinder 2〇〇 to form an inner syringe to which the semi-rotating cylinder 200 is fixed. The gap 〇2 between the other end of the inner syringe driver 203 of the driver spring 2〇4 and the inner syringe 2〇5 is interlaced φ (interlace) on the suture 20 wound on the semi-rotating cylinder 200 to be pulled by the wire The actuating member 401 is wound up from the suture 20 which is formed from the gap formed between the end of the inner syringe driver 203 to which the inner syringe driver spring 204 is fixed and the inner syringe 205 (18th (q) to ath) (w) Figure, Figure 52 (A)). In addition, the semi-rotating cylinder 20G stops the semi-rotation forward rotation while the crochet 13 is disengaged from the sewn body 21 to the top dead center (upper shaft 5: 720 degrees) (18th (V)th, 52nd (A) Figure). The wire pulling action member 4 〇 i φ advances and swings when the crochet pin 13 is detached from the body to be sewn 2 to tighten the stitch 20 (Fig. 18 (T), Fig. 52 (a)). When the crochet hook 13 is raised from the bottom dead center through the body to be sewn 2, the thread catching hook 13a of the crochet 13 is closed (i8 (T) map, Fig. 52 (A)). The drive tooth 601 starts the 1-stitch pitch transmission before the crochet 13 passes the top dead center (upper axis 5: 720 degrees) (1st 8th (W), 5th (2)) 〇〇(e) full When the needle 13 is detached from the object to be sewn 21 in the second stroke and rises through the top dead center (upper axis 5: 720 degrees), the stitching of the body to be sewn is -92-200827505 (90) 21 (1st 8th (w)th, 5th (2th)) (f) Repeating steps (a) to (e) respectively form hand stitch stitches on the surface of the body 21 to be sewn, forming an interlock on the inner surface Stitching stitches. Therefore, the thread catching hook that can reliably capture the suture 20 to the crochet 13

13a' and in the space inside the sewing machine base plate can be adapted to perform single-line interlocking stitching to form so-called point/saddle-like hand stitch-like stitching, and set the sewing direction of the stitched body 21 to be variable for each seam group. Can be suitable for sewing of single or multi-layer cotton or patchwork. Sewing stitches are formed on the surface of the body 21 to be sewn, and interlocking stitches are formed on the inner surface. The operator can visually observe the state of the hand stitches on the surface, and the hand stitch can be confirmed. The position can be correctly sewn. Further, since the stitch stitches are formed on the surface of the body 21 to be sewn, stitch stitches are formed on the inner surface, and the stitches 20 forming the single-line stitch stitching are not easily unwound by hooking. Firm sewing. Further, since the transmission amount setting mechanism 300 and the transmission mode switching mechanism 350 have the same configuration as the above-described single-line interlocking hand stitch, the explanation of the stitch pitch and the pitch adjustment between the stitches is omitted. Next, the single-line interlocking sewing stitch sewing machine for free-action sewing that can be switched by manual transmission/linear transmission is mainly based on Fig. 5 3, Fig. 54, 18(A) to (W), and 52(A), (C) diagram description. Figure 53 is an overall perspective view of a single-line interlocking hand stitch sewing machine for free-motion sewing, and Figure 49 is a block diagram showing a driving system of a single-line interlocking hand stitch sewing machine for free-action sewing. -93- 200827505 (91) The 5th (C) diagram is an operation diagram of the crochet 1 3, the semi-rotating cylinder 20 〇, the wire guide 8 1 1 and the metal pressing member 501. The 18th (A) to (W) and 52 (A) drawings are the same as the single-line interlocking hand stitch stitching machine for the free-curve sewing. And, the overall perspective view and the upper view shown in Figure 53

The first perspective view shows an overall perspective view. Although the shapes of the components used in the feed drive mechanism 70 0, the transmission amount setting mechanism 300, and the transmission mode switching mechanism 350 are different, the shape is improved only during the product formation, and the configuration thereof is The semi-rotating cylinder 200, the pressing mechanism 500, the feeding mechanism 600, and the wire pulling drive mechanism 400, which have the same operation, are the same in the configuration and operation, and therefore the same reference numerals will be given thereto, and the description thereof will be omitted. Further, the single-thread interlocking hand stitch sewing machine for free-motion sewing is a transmission/linear transmission switching mechanism 740 using a wire mechanism 800B and a pressing release mechanism 720A and a transmission tooth retracting mechanism 720B. Further, the syringe driving mechanism 220 is similar to the single-line interlocking hand stitch sewing machine for free-curve sewing, and the cylinder driving sector gear 233 shown in FIGS. 50 and 51 is in the cylinder shaft gear 224. The lower jaw is configured to be fixed, and the syringe driving sector gear 233 is fixed to the sector gear shaft 235. Therefore, the cylinder driving longitudinal rod 228 shown in Fig. 50 and Fig. 51 is formed in Fig. 14 and Fig. 15 The needle drive longitudinal rod 228 is short. Similarly, in the same manner as the single-line interlocking hand stitch sewing machine for free-curve sewing, the force of the stitch transmission adjustment lever 3 0 1 and the inter-stitch transmission adjustment lever 302 is formed. A transmission adjustment lever knob 323 is attached to the position of the point.

In Fig. 53 and Fig. 54, the driven pulley 4 driven by the drive belt MB-94-200827505 (92) is rotated by the upper shaft 5 when the driven pulley 4 driven by the drive belt MB-94-200827505 (92) is rotated from the crochet 13 side to the clockwise direction. The crochet/cover needle driving mechanism 1 3 〇, the feeding drive mechanism 700, the 'spindle driving mechanism 220, the wire traction driving mechanism 400,

The manual transmission/linear drive switching mechanism 74A, the wire mechanism 800B, and the wire insert drive mechanism 450 are driven. When the crochet/cover needle driving mechanism 13 is driven, the crochet 13 linearly reciprocates in the vertical direction, and when the syringe driving mechanism 220 is driven, the inner cylinder 206 of the semi-rotating cylinder 200 is rotated half-rotation forward and half-rotated, and the linear traction drive is driven. When the mechanism 400 is driven, the swing wire pulling action member 401 is driven, and when the swing operation/linear drive switching mechanism 740 is driven, the pressurization of the metal press member 501 is released for each of the first stroke and the second stroke of the crochet 13 for a predetermined time, and the feed drive is stopped. The mechanism 700 causes the transmission teeth 601 to be retracted frequently. When the wire mechanism 800B is driven, the first and second strokes of the crochet 13 cause the wire guide 8 1 1 to move elliptically near the crochet 13 3 , and the wire insertion drive mechanism 450 drives At the time of each of the first stroke and the second stroke of the crochet 1 3, the thread insert 45 1 is reciprocated. In addition, the description of the operation of each mechanism is omitted in the above description of the configuration. The above-mentioned action of the crochet 13, the semi-rotating cylinder 200, the wire pulling action member 104, the transmission tooth 601, the metal pressing member 501, the wire pulling action member 104 and the wire insert 451 are synergistically as follows. A stitch stitch is formed on the surface of the body 21 to be sewn by one stitch 20, and a stitch stitch is formed on the inner surface. Further, in the case of linear transmission, the same sewing operation as that of the above-described single-line interlocking hand stitch sewing machine (Figs. 1 and 2) is omitted, and the description thereof is omitted. Switching the switching lever 542 to the swing operation transmission (free-action sewing) -95- 200827505 (93) When the sewing machine is driven, (a) the crochet 13 that reciprocates linearly in the vertical direction from the top dead center (upper axis) in the first stroke 5 ·· 0 degree) is lowered through the body 21 to be placed on the needle plate 12 (Fig. 18(A) to Fig. 18(F), Fig. 52(A)), by the bottom dead center (upper axis 5) : 180 degrees) When rising, the line catching hook 13a catches the line. The line exit 212a of the semi-rotating cylinder 200, which is reversed by the lower half of the needle plate 12, is led out by the wire pulling action member 401 and is circumferentially connected to the crochet.

13 Tightening suture 20 (Fig. 18 (G), 18 (H), 52 (A)). At this time, the semi-rotating cylinder 200 has the wire outlet 212a of the bobbin case 212 as shown in the figure 20 (B), and the crochet 13 is disposed to the inner syringe of the semi-rotating cylinder 200 when it is lifted from the needle plate 12. The 205 is reversed from the direction and position in which the needle plate 12 is separated. Thereby, the suture 20 leading from the wire pulling action member 40 1 can be attached to the crochet 13 . Further, while the wire pulling action member 401 is taken out from the wire exit 212a of the bobbin case 212, the wire catching hook 13a of the crochet 13 is positioned so that the stitching line 20 is tightened by the crochet 13 The line of the plug-in 4 5 1 is forcibly inserted into the line of the saturated needle 1 3 to capture 13 3 (Fig. 18(F) to Fig. 18(K), Fig. 44, Fig. 52(C)). Further, the crochet 13 is rotated substantially from the top dead center (upper axis 5: 0 degrees) to the bottom dead center (upper axis 5: 180 degrees) to stop the semi-rotating cylinder 200. Since the rotation stop semi-rotating cylinder 200 is hooked to the thread catching hook 13a of the crochet 13 in the first stroke, the cylinder that performs the half-rotation forward rotation in the second stroke is half-rotated. The timing of the reversal. Further, when the crochet 13 in the first stroke of the crochet 13 is detached from the body 21 to be sewn, the pressing of the metal pressing member 501 is released, and the gear 601 of the transmission-sewed body 21 is retracted. (18th (J) to 18th (N), 52nd (C)). Thereby, the object to be sewn 21 can be manually driven while the stitch distance transmission amount and the inter-stitch distance transmission amount are arbitrarily given in the first stroke of the crochet 13. Furthermore, the drive teeth 601 are often retracted by the drive tooth retraction mechanism 720 during this manual drive.

Further, the semi-rotating cylinder 200 starts the half rotation reversal after the crochet 13 is inserted into the body 21 to be sewn (upper axis 5: 13 0 degrees) (Fig. 18(E), Fig. 5 2 (A)). The wire pulling action member 401 is stopped at the most advanced position before the crochet is inserted into the body 21 (upper axis 5: 8 degrees) (Fig. 18 (D), Fig. 52 (A)). The cover pin 14 is opened when the crochet 13 is inserted into the body 21 to be sewn (Fig. 18(E), Fig. 52(A)). (b) During the first stroke, the crochet 13 is lifted from the object to be sewn 21 and passes through the top dead center (upper axis 5: 3 60 degrees), and the stitching speed of the body 21 is transmitted by the gear teeth 601. At the same time, the crochet 13 of the catching suture 20 is raised and the semi-rotating cylinder 20 0 is reversed to be wound up (18 (1) to 18 (M) and 52 (A)). Further, the semi-rotating cylinder 200 stops the semi-rotation reversal after the crochet 13 passes the top dead center (the upper shaft 5 ··3 60 degrees) (the upper shaft 5 : 3 67 degrees) (the 18th (M) map, the 52nd ( A) Figure). The wire pulling action member 401 starts to retract the swing when the saturated needle 13 reaches the bottom dead center (upper axis 5: 180 degrees), and can send the stitch 2 〇 (Fig. 18 (F), Fig. 52 (A)), crochet 13 Stop backward by the top dead center (upper axis 5:3 60 degrees) (Fig. 18(L), Fig. 5 2 (A)). The cover pin 14 passes through the needle plate when the crochet 13 moves from the bottom dead center (upper axis 5: 18 degrees) to the top dead center (upper axis 5: 366 degrees). After 12, the thread catching hook 13a of the crochet 13 is closed, so that the body 21 and the crochet 13 pass together (i8 (j), 18 (K), and 5 (A)). Further, in the first stroke of the crochet 13, the thread guide 81 1 also causes the elliptical motion of the end portion 8lla as shown in Fig. 29 to be only one rotation in the horizontal direction (18th (A) to 18th ( M) map, Fig. 5 (A)), at this time, the saturating needle 13 does not catch the suture 20 even if the descending line catches the hook 1 3 a.

(c) The crochet 13 descends from the top dead center (upper axis 5: 360 degrees) through the sewn body 21 in the second stroke (18th (N), 18th (0)th, 52nd (A)) When the bottom dead center (upper axis 5: 540 degrees) rises, the slanting collar 205a of the semi-rotating cylinder 200 that rotates in a semi-rotation direction captures the stitching line 20 captured by the hook 13a, and at the same time, by the half-rotating needle The rotation of the canister 200 releases the captured suture 20 from the line catching hook 13a (the first 8 (P) map, the 52 (A) map). Further, the crochet 13 is substantially from the top dead center (upper axis 5: 3 60 degrees) When the movement to the bottom dead center (upper axis 5: 540 degrees), the rotation of the φ moving semi-rotating cylinder 200 is stopped. The above rotation stops the semi-rotating cylinder 200 in order to hook the crochet 13 in the second stroke. The thread capture hook 1 3 a of the suture 2 0 is opened at the horn collar 205a of the syringe from the line catching hook 13a, and the timing of the half rotation of the cylinder reversed in the first stroke is reversed. The semi-rotating cylinder 200 starts the semi-rotation forward rotation when the crochet 13 reaches the bottom dead center (upper axis 5: 540 degrees) (Fig. 18(P), Fig. 52(A)). The wire pulling action member 401 is at the crochet 13 is inserted into the body 21 to be sewn , retreat and start swinging and sending the suture 20 (Fig. 18 (N), Fig. 52 (A)). The cap 14 is lowered when the crochet 13 is lowered from the top dead center through the sewn -98 - 200827505 (96) body 21 The line catching hook 13a of the crochet 13 is formed in an open state (Fig. 18 (〇), Fig. 52 (A)).

Further, in the second stroke of the crochet 丨3, the leader 811a performs only one rotation in the horizontal direction in the elliptical motion of the motion locus 830 as shown in Fig. 29 (18th (M) to 18th (W ) Figure, Figure 52 (C)). At this time, when the crochet 13 is lowered, the suture 20 caught by the thread catching hook 13 a of the crochet 13 between the needle tip of the saturating needle 13 and the body to be sewn 2 can be loosened from the contracted state. Therefore, the wire is loosened between the needle tip of the crochet 13 and the body 21 to be sewn toward the non-opening direction of the wire catching hook 13 a with the leading end portion 8 1 1 a of the wire guide 8 1 1 (the 18th ( M), (N), and 52 (C)). Specifically, as shown in FIG. 29, the elliptical motion of the trajectory of the front end portion 8 1 1 a of the wire guide 8 1 1 is a clockwise direction when the metal pressing member 510 is displayed from above, and the trajectory can be formed. The position of the wire point of the 830 is 83 0a. The coil of the stitch 20 is caught in the non-opening direction of the hook 13 3 a with the leading end φ portion 8 1 1 a of the wire guide 8 1 1 and the front end portion 8 1 1 a hook hang. Further, the position 830b of the motion locus 830 as shown in Fig. 52(C) is the position shown in Fig. 29. When the crochet 13 is detached from the object to be sewn 21 in the second stroke of the crochet 13, the pressing and holding of the metal pressing member 501 is released, and the transmission teeth 601 of the transmission-sewed body 21 are retracted (18 (T) to 18). (E), Figure 52 (C)). The stitched body 21 can be manually driven while the stitch pitch transmission amount and the inter-stitch pitch transmission amount are arbitrarily given in the second stroke of the crochet needle 13. -99- 200827505 (97)

Further, when the inner cylinder 205 of the semi-rotating cylinder 200 has, for example, a convex line retention portion of 2 0 5 g, the semi-rotation forward rotation position of the inner needle cylinder 205 as shown in the first 8 (U) is formed. As shown in Fig. 47, the thread retaining portion 205g which can maintain the convex shape is hooked with the suture 20, so that the suture thread penetrating the semi-rotating cylinder 200 can be temporarily retained, and then the actuating member 401 can be pulled by the wire. The thread is wound up from the suture threaded through the semi-rotating cylinder 200 to release the temporary retention of the suture. Therefore, in the second stroke of the crochet 13, the suture 2 which is formed in the gap 〇2 between the other end of the inner syringe driver 203 to which the inner syringe driver spring 204 is fixed and the inner syringe 205 is inserted even though When the syringe 2〇5 is rotated halfway, it can still maintain the tightening state, and does not loosen the suture 20 which penetrates the semi-rotating cylinder 200 and the suture 20 which is derived from the line outlet 2 1 2 a. The front end of the wire pulling action member 4 0 1 can be caught by the cloth 4 0 1 a. Further, in the second stroke of the crochet 13 3, the thread insert 4 5 1 is similarly (the 1st (8th) to the 18th (S)th, 5th (C)), and the suture 20 is It is not positioned on the line catching hook 1 3 a of the crochet 13 . (d) The suture 20 released by the horn collar 205a of the semi-rotating cylinder 200 is rotatably inserted through the semi-rotating cylinder 200 to form an inner syringe driver spring to which the semi-rotating cylinder 200 is fixed. The gap between the other end of the inner syringe driver 2 0 3 and the inner syringe 2 〇 5 is interlaced at the stitch 2 of the semi-rotating cylinder 2〇〇 to The wire pulling action member 104 winds up the stitch 20 from the gap 〇1 formed between the end of the inner syringe driver 203 to which the inner syringe driver spring 204 is fixed and the inner syringe 2〇5. (1st 8th (Q)~1st 8th (W) and 5th (A)). -100-200827505 (98) In the semi-rotating cylinder 200, the semi-rotation forward rotation is stopped while the crochet 13 is disengaged from the sewn body 21 to the top dead center (upper axis 5: 720 degrees) (18th (V) ) Figure, Figure 52 (A)). The wire pulling action member 40! starts to swing when the crochet pin 13 is detached from the body to be sewn 2 to tighten the stitch 2 〇 (Fig. 18 (T), Fig. 52 (A)). When the crochet hook 13 is raised from the bottom dead center through the body 21 to be sewn, the needle catching hook 13a of the crochet 13 is closed (18th (T)th, 52nd (A)).

(e) The crochet 13 is detached from the object to be sewn 21 in the second stroke and rises through the top dead center (upper axis 5: 720 degrees), and the inter-pitch pitch transmission of the body 21 is performed (1st 8 ( W) Fig. 52 (A) Fig. (f) The steps of (a) to (e) are repeated to form stitch stitches on the surface of the body 21 to be sewn, and stitch stitches are formed on the inner surface. Therefore, the suture 20 can be surely caught to the thread catching hook 13 3 a of the crochet 13, and the space in the sewing machine bottom plate can be adapted to perform single-line interlocking φ stitching to form a so-called point/saddle-like hand stitch-like sewing. And the sewing direction of the sewn body 21 is set to be variable for each seam group to be suitable for sewing of a single or multi-layer cotton cloth or a patchwork. Sewing stitches are formed on the surface of the body 21 to be sewn, and interlocking stitches are formed on the inner surface. For the operator, the surface can be visually observed in the state of the hand stitches, and the sewing of the hand stitches can be confirmed. The position is correctly sewn. Further, since the stitch stitches are formed on the inner surface by forming the stitch stitches on the surface of the body to be sewn 2, the stitches 20 which form the single-line stitch stitching are not easily unwound. A firm sewing is obtained. -101 - 200827505 (99) Further, the transmission amount setting mechanism 300 and the transmission mode switching mechanism 350 have the same configuration as the above-described single-line interlocking hand stitch, and therefore the correlation between the stitch pitch and the stitch spacing adjustment is omitted.
