The left edge (the side edge in the L direction) of 930 is formed with opposite side edges 930C. A tip end wall 930D having a flat portion at right angles to the longitudinal direction of the first link belt 916 is formed at an end portion before the opposite side edge 930C. In the pin 930 described in Patent Document 1, the extension line EL which extends the flange sliding side edge 930F downward (in the D direction) is the father in a direction substantially perpendicular to the tip end wall 93OD. The intersection of the extension line EL and the top end wall 93A is defined as the intersection ND. The configuration of the previous reverse zipper 910 will be described later using FIG. Figure 12 is a view showing the lower end of the upper sliding member 50 which is pulled down to the upper sliding end of the upper sliding member 50 and the lowering end of the lowering member 6'. The latch 930 which is first unscrewed as if the reverse opening button 91 is opened is again A diagram showing the state in which the introduction port on the right side (R direction) of the upper slider 50 is inserted. Further, Fig. 12 is a cut surface substantially parallel to the chain fabric U, and the cut surface between the upper slide member 50 and the lower slide member 60 and the i-th and second chain belts 916, 17 will be placed. The slider 50 and the slider 6 are cut, and a plan sectional view of the inside of the element guide passages 50T, 60T is exposed. The reverse zipper 910 shown in Fig. 12 is, for example, an opening and closing device that can open and close the left front body and the right front body of a long coat or the like. The reverse zipper 9 丨〇 is provided with: a pair of left and right chain cloths 11; anger portions 14 respectively formed along opposite end edges of the chain cloth 丨 1 and arranged at specific intervals in such a manner as to sandwich the respective core 丨 4 A plurality of first and second sprocket teeth 12 and 13. 146171.doc 201108963 Further, the reverse zipper 910 is provided with a row of the first and second sprocket wheels 12, 13 inserted to open the upper slider 50, and a reversible sliding member 〇. I. The upper teeth of the upper part are disposed opposite to the fitting opening of the lowering member 60. As shown in Fig. 12, a reinforcing film 24 such as a resin film is adhered to the inside and outside of the end portions (1) of the first and second chain belts 916 and 17 below. The pin 930 and the pin 4 are respectively connected to the & and the second chain 12, 13 in the form of the reinforcing film 24 and the core portion 14 interposed therebetween. A hook-shaped collision is formed at the lower end of the pin 4G (end portion in the D direction). The stop 46 is attached to the lowermost portion of the binding member, and is abutted against the portion of the sliding portion of the sliding member 60. Or the end of the flange trace prevents the drop member from falling off underneath. The embodiment shown in Fig. 12 causes the stop buckle to protrude from the lower end of the pin to the left direction (L direction). The lower end of the flange 60F of the lowering member 60 is fitted. The outer flaps (not shown) and the inner fins of the upper slider 50 shown in Fig. 12 are attached to the left and right centers of the upper slider 50 (the central portion in the L_R direction). The top (1) direction knives are fixed to each other by the guide post 50D. The flanges are extended in a relative shape from the left and right sides of the upper slider 5 and the inner flap 53. A sprocket guiding passage 50T is formed in the inner portion of the upper sliding member 5〇 surrounded by the outer flap, the inner flap 53, and the flange 5〇F, and is a γ-shaped space in a plane view, and is inserted into a pair of left and right sides. The first sprocket 12 row and the second sprocket 13 row. In addition, on the outer surface side of the upper π piece 50 outer blade (the paper surface shown in FIG. 2 is close to the observer side) ^/ has a supporting upper sliding member The pull-tab support (not shown) which can be freely poured by the pull-on piece of 50. The left and right sides (L_R direction) of the guide post 50D of the upper slide member 50 are respectively opened [S] 146171.doc 201108963 The introduction passage D of the guide passage 50T is opened at the lower end portion (4) of the upper slider 5 () toward the end portion thereof) with the key opening of the key guide passage. At the edge portion of the flange, along the flange 50F The end edge is formed with a chain insertion passage (not shown). The hinge insertion passage is formed by fixing a gap of the chain cloth 11 inserted through the rows of the second and second fastener elements 12 and 13 of the element guide passage 50Τ. And sliding the portion of the chain cloth 11 when the upper slider 50 slides. "The lowering member 60 shown in Fig. 12 is also identical to the upper sliding member 5'', and is formed with an outer flap (not shown). The sheet 63, the guide post, and the flange 縦 are formed with a sprocket guiding passage 6GT, an introduction port, a ringing port, and a chain insertion passage. Further, a tab support (not shown) for supporting the slider of the slide member 6〇 to be freely tilted is formed on the surface of the flap outside the slider 60. As shown in FIG. 12, when the first belt 916 and the second chain belt 17 are once again separated from each other, the unplugged pin 93 is pushed out from the inlet of the upper slider 50 (Fig. In the example shown in Fig. 12, the insertion port on the right side (R direction) is inserted. At this time, the latch 930 is inserted from the introduction port of the upper slider 50 so that the latch 930 and the pin 40 are parallel in the sprocket guiding passages 50 and 60T of the upper slider 50 and the lower slider 6 ,. The user holds the vicinity of the reinforcing film 24 at the lower portion of the first chain belt 916, and as shown in Fig. 12, the surface is rotated counterclockwise and inserted downward (D direction). However, if the vicinity of the reinforcing film 24 at the lower portion of the first link belt 916 is not rotated in the counterclockwise direction, the latch 930 is arbitrarily moved straight in from the introduction port of the upper slider 5'. As shown in FIG. 12, at one of the latches 930 When the side edge is slidably attached to the flange 50F of the upper slider 5〇 and the other side edge is slidably coupled to the barrel pin 40, the top end wall 930D formed substantially in the form of an extension line EL may be guided by the sliding member 60.桎146171.doc 201108963 6〇D (especially near the apex of the guide post 6〇D) conflicts from the front. In the general reverse zipper 910, the collision with the guide post 60D occurs in the vicinity of the intersection ND where the tip end wall 930D and the extension line EL intersect. At this time, since the distal end wall 930D of the latch 930 collides with the surface of the guide post 60D from the substantially normal direction, the latch 930 can no longer be pulled downward (in the D direction). And the latch 930 will stop at a position where the guide post 6〇D collides (i.e., the position where the latch 93〇 does not reach the lowermost end). At this time, the user feels that the pin 930 inserted from the introduction port of the upper slider 5 is stopped according to the tactile sensation, and the pin 930 is mistakenly inserted into a specific position. When the user judges that the latch 930 has been inserted into the specific position, the user then performs an operation of sliding the upper slider 5 upward (U direction) to close the reverse zipper 910.

However, as shown in FIG. 12, in a state where the top end wall 930D of the latch 930 is in contact with the upper portion of the guide post 60D (the top in the U direction), the second element 13 which is fixed to the directly above the pin 40 should be attached. The i-th sprockets 12 of the opposite sides of the meshing are not lowered to a specific position. Therefore, even if the upper slider 50 is slid upward (u direction) from the state shown in FIG. 2, the second sprocket 13 fixed to the upper side of the cylinder pin 4 is still in conflict with the upper portion of the latch 930, and The second sprocket 13 and the latch 930' cannot be engaged with each other in a state in which the latch 930 is caught on the inner surface of the flange 5〇F of the upper slider 50. Therefore, the upper slider 5 cannot be slid upward (u direction). Here, if the user barely slides the upper slider 50 upward (u direction), there is a risk that the reverse zipper 910 is broken. Moreover, the user feels that the operation of the zipper is reversed when the last monthpiece 50 cannot slide. 146171.doc 201108963 is better. The present invention has been completed in view of the above problems, and an object thereof is to provide a reverse-opening zipper which performs an opening and closing of a left and right chain belts, wherein the left and right key belts which are once turned into an open state are mutually When it is combined again, the pin can be smoothly inserted into a specific position even if the pin-face is freely moved from the guide of the upper slider to the face-in. Means for Solving the Problem In order to achieve the above object, the reverse zipper of the present invention includes: a pair of right and left first and second chain belts; a latch and a pin which are disposed opposite to the inner side of the first and second key bands; a lower end of the edge portion; and an upper slider and a lowering member that open and close the first and second chain belts; and the upper sliding member is disposed in a direction in which the sealing openings are opposed to each other, and the plug is driven from the upper sliding member When the guide inlet is inserted into the upper sliding member, the front end of the latch can be inserted over the top of the fitting port side of the guiding post of the sliding member; wherein the latch includes: the pin sliding side of the pin side And a flange sliding side edge on the inner side of the chain cloth disposed opposite to the pin sliding side edge; the first side of the pin sliding side edge is formed! The inclined portion is inclined toward a front end of the pin and separated from the cylindrical pin; the i-th inclined portion is extended from a flat portion of the flange sliding side edge to an end side of the plug front end side When the plug is inserted into the upper sliding member, the first inclined portion has a shape that is inclined at an angle to the guide post of the sliding member or separated from the guide post. Further, it is preferable that the side surface of the inclined portion of the pin sliding side edge is formed as a continuous curved surface. Further, it is preferable that the flange sliding side edge on the side opposite to the first inclined portion is formed at a front end facing the plug and inclined from the cylindrical pin: The inclined portion between the first inclined portion of the pin sliding side edge and the second inclined portion of the flange sliding side edge is gradually decreased toward the front end of the pin. Furthermore, it is preferable that the sliding member includes an inner and outer fins connected by the guide post and a stopping claw disposed on one of the inner and outer fins, and the end portion of the plug before the latch The surface of the stopping claw side is formed with a claw guiding inclined surface that is inclined so as to gradually decrease the thickness of the plug toward the distal end of the plug. The claw guiding inclined surface is disposed across the extension line. Advantageous Effects of Invention In the reverse zipper of the present invention, it is preferable that the plug has a pin sliding side edge disposed on the pin side and a flange sliding side disposed on the inner side of the chain cloth, and The pin sliding side edge is formed with a first inclined portion that is inclined toward the tip end of the pin and that is inclined away from the direction of the pin side. Further, the first inclined portion formed on the side edge of the pin sliding contact is formed by intersecting an extension line extending the flat portion of the flange sliding side edge on the end side of the pin, and the third inclined portion is The pin is inserted into the upper and lower π pieces, and has a shape inclined at an angle to or in contact with the guide post of the down piece. In particular, the first inclined portion of the pin sliding side edge has a shape that is inclined at an angle to the pin side surface of the lower member or to the pin side surface. According to the reverse zipper of the present invention having such a configuration, when the left and right chain belts that are once opened are recombined with each other, the plug can be smoothly inserted even when the plug is freely inserted from the introduction opening of the upper slider. Insert L S3 146171.doc 201108963 to its lowest position. In more detail, '(4) when the pin is inserted into the upper sliding member from the upper sliding member', for example, when the base end side of the flange sliding side edge of the pin is slidably attached to the flange of the upper sliding member, and (4) sliding In the case where the front end (4) of the Qianyuan is connected to the pin, 'because the top end wall (front end face) of the previous plug as described above will collide with the guide post of the lowering member, there is a problem that the insertion operation of the latch is hindered. On the other hand, the present invention is in the case where the base end side of the flange sliding side edge of the pin is slidably attached to the flange of the upper slider and the end side of the pin is slidably coupled to the pin before the pin side is slid And the first inclined portion of the latch is connected to the guiding post of the sliding member (in particular, the side of the guiding post), and the front end of the latch is received in the direction separating from the tubular pin by the inclination of the (10) inclined portion. - The face is crossed over the top of the guide column and the top of the side is inserted. Alternatively, the p-inclined portion of the latch and the guide post (four) of the lower member are not inserted, and the tip end of the guide post is inserted into the distal end of the latch. Thereby, the plug is not stopped by the collision with the guide post of the down piece, and the pin can be smoothly inserted into the lowermost position. In addition, here, the lowermost position of the plug means that the front end of the latch reaches the position of the top of the salivation port side of the bow guide post of the lowering member, and the position of the latch is substantially parallel to the cylinder. x, the side of the guide post means the inclination of the surface with respect to the longitudinal direction of the slider (the inclination of the wiring when the surface is a curved surface) is 45. The wall of the guide post below. Further, in the present invention, the side surface of the second inclined portion of the pin sliding side edge (particularly, the opposite side surface facing the guide post of the sliding member of the first inclined portion) may be formed as a continuous curved surface. Thereby, when the plug is inserted from the inlet of the upper slider, the leading end of the latch can be more reliably prevented from colliding with the guide post of the slide member 14617l.doc 12 201108963, and the latch can be inserted into the lowermost position more smoothly. Further, by making the side surface of the first inclined portion a curved surface, the length of the plug can be shortened. Therefore, the pin can be housed in the element guide passage of the upper slide member in a state where the slide member is pulled down to the lowermost position, so that the plug can be prevented from the outside. Further, the reverse zipper of the present invention may be configured such that a second inclined portion is formed on the flange sliding side edge of the pin, which is inclined to a direction away from the end portion of the pin and separated from the tubular pin side; The width dimension between the i-th inclined portion of the sliding side edge and the second inclined portion of the flange sliding side edge decreases toward the tip end of the pin. Thereby, the strength of the front end portion of the pin can be maintained and the first inclined portion can be formed reliably, and the flange sliding side edge and the flange of the sliding member can be prevented from interfering with each other when the pin is inserted, and the latch can be smoothly and stably performed. Insert operation. Further, in the present invention, the surface of the end portion before the pin is formed to have a claw guiding slope which is inclined so as to gradually decrease the thickness of the latch toward the distal end of the pin. Thus, by making the illusion of the illusion of the illusion with the extension line and forming it transversely across the extension line, the claws are abundant. + (on the curved surface) cooperate with each other, so that the surface of the end before the bolt presents a spherical β-zinc. For example, from kt (3) Even if the front end of the pin moves linearly or moves with the rotation r even when the pin is inserted, the sliding member can be surely stopped. The claw is slid to the claw guiding the inclined surface and the sling is stopped - ^ 3 the claw guiding the inclined surface is guided, so

The sliding member 50 and the lowering member 6〇 on the zipper 10 are reversely inserted in a state in which the second sprocket 12 and 13 are respectively inserted into the sprocket guiding passages 5〇τ′ 6〇τ, as described above. The lowering member 60 is disposed closer to the latch 3 〇 and the pin 40 side 'and' than the upper slider 50 so that the fitting port of the upper slider 5 相对 is disposed opposite to the slamming port of the lowering member 6 。. Further, when the slide member 60 is slid over the upper side (υ direction) as shown in Fig. 1, the first and second sprocket wheels 12 and 13 in the engaged state are introduced from the engagement opening. The first and second sprocket wheels 12 and 13 which are guided in the engaged state are separated in the left-right direction (L-R direction) along the guide post 60D, and are discharged from the introduction ports at the lower side (D direction) shown in Fig. 1 . Further, when the left and right first and second sprocket wheels 12 and 13 are inserted into the element guide passage 60A, the slide member 60 is slid downward (in the D direction) as shown in FIG. The first and second sprocket 1 2, 13 rows in the separated state are introduced from the introduction port of the left and right (LR direction) of the lowering member 6〇. The first and second sprocket 12 and I3 introduced are arranged along the row. The inner wall of the flange 5〇F of the sprocket guiding passage 60 is guided to merge and is engaged, and is discharged from the engaging opening at the upper side (U direction) of Fig. 1 . 146171.doc -26- 201108963 If the lowering member 60 is further pulled downward (in the D direction), the pin and the pin 30 are introduced from the introduction port of the sliding member 60, so that the pin is formed at the lower end of the pin. 46 is stopped by the portion of the inlet of the lowering member 6〇. This position becomes the lowermost end of the lowering member 60. When the left and right first and second sprocket teeth 12 and 13 are sprayed and separated from each other, the upper slider 50 is pulled downward (in the D direction) up to the upper state in a state where the lower slider 6 〇 is moved to the lowermost end. The spray port of the slider 5 is abutted against the position of the fitting port of the slide member 6〇. In this way, the state of all the ninth and the second key ΐ 2' Η 解 is released. Thereafter, the portion of the reinforcing film 24 that grips the lower end of the second chain belt 16 is pulled in this state, and the pin 30 is pulled upward (in the U direction). In this manner, the latch 30 can be pulled out from the sprocket guide passage 5 of the upper slider 50 and the lower slider 6 ,, and the left and right 丨 chain belt 16 can be separated from the second chain η. When the left and right chain links 16 and the second chain belt 17 are once again combined, the reinforcing film at the lower end of the second chain belt 16 is held in part, and from the left direction of the upper slider 50 (L). Insert the pin 3〇 into the inlet of the direction). The V-shaped person inserting the latch 3G from the upper slider 50 causes the front end of the latch 3G to face nr π + 丄, ^ 1 〒, 纷 w円 downward (1) in the sprocket guiding passage 60T of the sliding member The state of sliding is the state shown in FIG. 6. When the plug is inserted deeper in the state shown in FIG. 6, the flange sliding side edge of the pin 3〇 is slidably coupled with the flange 5qf of the upper slider, and the guiding surface 33 of the latch 30 is The guide post of the upper slider 5G is slidably connected, and the latch % moves downward (in the D direction). When the latch 30 is inserted deeper in the state shown in Fig. 6, the stopper claw 64 abuts against the outer wall 3() τ at the end of the plug 30. At the front end of the plug view ^ I46l71.doc -27- 201108963, the claw guiding bevel 3 9 is formed such that the outer wall 30 is gradually inclined toward the inner side of the inner wall 30 so as to gradually reduce the thickness of the pin 30, and the claw guiding the inclined surface 39 is reached. The stop claw 64 is connected. If the pin 30' is inserted further downward (in the D direction) in a state where the claw guiding slope 39 abuts the stopping claw 64, the stopping claw 64 will face outward as the stopping claw 64 is slidably attached to the claw guiding slope 39 of the latch 30 ( τ direction) retraction (refer to Figure 7). Thus, the end portion of the front end of the latch 30 can be inserted into the plug 3〇 further downward (in the D direction) by the portion of the slide member 6 which is protruded by the stopping claw 64. In this case, the front end of the plug 30 in which the claw guiding slope 39 is formed is formed as shown in Fig. 7 with respect to the center line of the inner and outer directions of the plug 30, which is offset from the inner wall 3〇β side. Further, the front end of the latch 30 is located closer to the inner surface (Β direction) than the protruding end of the stopping claw 64 in a state where the stopping claw 64 protrudes from the element guiding passage 60. In particular, the 's sea claw guiding slope 39 is continuously formed at the position where the first inclined portion 3 is formed. In other words, the claw guiding slope 39 is formed to be transversely formed across the extension line EL, and the claw guiding slope 39 is disposed on the surface side of the first inclined portion 30E that intersects the extension line. Therefore, the surface claw guiding slope 39 at the end portion of the front end of the latch 3 is fitted to the curved surface of the first inclined portion 3〇E to be spherical. Thereby, for example, when the plug 3 is inserted, even if the insertion of the latch 30 is performed in a straight line or with rotation, the stop claw of the slide member 6 can be surely guided to the outside by the claw guiding slope 39 (τ The direction is on the side, and the stop pawl 64 can be safely retracted. When the plug 3 is further inserted straight into the state shown in FIGS. 6 and 7, as shown in FIGS. 8 and 9, the first inclined portion on the side of the pin 3 〇c side of the pin 3 〇 before the end of the pin 3 插The 30E will face the guide post 6〇1) of the sliding member 6〇.

In other words, the 'previously reversed zipper 910 is such that the flange sliding side edge 930F of the latch 930 contacts the flange 5〇f of the upper slider 50, and the opposite side edge of the latch 3〇 (the pin sliding side) When the rim 930C is inserted into the latch 930 in contact with the opposite side edges of the pin 40, there is a problem that the tip end wall 930D of the latch 930 collides with the guide post 60D and thus hinders the insertion of the latch 930. On the other hand, as shown in FIG. 8 and FIG. 9, the first inclined portion 30E of the pin sliding side edge 30C on the end side of the plug 3 is formed so as to face the front end of the pin 30 and An inclined surface (curved surface) in which the direction in which the pin 40 is separated is inclined. That is, the front end portion of the plug 30 is formed as an inclined surface which is gradually inclined toward the flange sliding side edge 30F side toward the front end portion. Further, the inclined surface is formed in such a manner that the inclined surface faces the facing surface of the guide post 60D of the slide member 60, and the positional relationship with the guide post 60D is determined. That is, the inclined surface of the first inclined portion 30E is slidably attached to the flange 5〇f of the upper slider 50 at the flange sliding side edge 30F of the latch 30, and the pin sliding side edge 30C of the pin 3〇 is slid In a state of being connected to the opposite side edge 40C of the tubular pin 40, the shape is inclined at an angle separated from the guide post 60D of the slide member 60 (in addition, the inclined surface of the i-th inclined portion 30E may be formed to be aligned with the guide post. The angle of the 6 〇D pin side is connected to the angle of the angle). By forming the latch 30 having the ith inclined portion 30E, the front end of the latch 30 can be prevented from coming into contact with the guide post 60D of the lowering member 6〇, and the contact area of the latch 3〇 can be prevented from coming into contact with the guide post 6β. Thereby, the latch insertion operation can be performed smoothly. Further, in the case of a crucible, the latch 30 is configured such that the contact point with the pin 40 of the pin sliding side edge 30C is in contact with the pin-sliding side edge 3〇c 146171.doc • 30-201108963 The interval (distance) between the intersections ND of the extension wires EL is larger than the interval (distance) from the contact points to the apexes of the guide posts 60D of the slider 60, and the side shape of the first inclined portion 30E of the latch 30 is Formed into a continuous curved surface shape. Thereby, it is possible to surely prevent the pin 3〇 from coming into contact with the guide post 60D of the slide member 6〇, so that a more stable pin insertion operation can be performed. Further, the second inclined portion 30G formed on the side of the flange sliding side edge 3〇f of the plug 30 is more relaxed than the above-described inclination angle of the i-th inclined portion 3〇E. Therefore, when the pin 3 is inserted, the second inclined portion 3〇g of the latch 3〇 does not come into contact with the flange 60F of the slide member 60. In another case, for example, when the pin 3 is inserted from the introduction port of the upper slider 50, the pin 30 is slightly rotated by one side to insert it, and the flange sliding side edge 30F of the pin 3 is slidably attached to the upper slider. The flange 5〇f of 5〇, but also the case where the pin sliding side edge 30C of the pin 3 is not slidable with the opposite side edge 4〇c of the pin 40. In the case of the case, as before, it is possible to prevent the front end of the pin 3 from colliding with the guide post 6〇d of the slide member 60, so that the pin insertion operation can be smoothly performed. Thereafter, when the plug 30 is further inserted downward (in the D direction) from the state shown in FIGS. 8 and 9, the latch 30 is gradually rotated in parallel with the pin 4, as shown in FIG. Insert the pin 3 into the lowermost end. In addition, although not shown, the ith fastening portion 34 (see FIG. 3) of the latch 3A abuts against the second fastening portion 44 (see FIG. 3) of the tubular pin 40, The latch 30 is positioned at the lowermost end. Moreover, the parallel direction of the pin 30 and the pin 40 means that the flat portion of the pin sliding side edge 30C of the pin 3〇 or the flat portion of the flange sliding side edge 3〇1? and the opposite side edge of the pin 4〇 40C is parallel to each other. As described above, the "reverse-opening zipper of the present invention" can surely avoid the conflict of the front end of the latch 30 even when the front end of the latch pin 146171.doc -31 · 201108963 is inserted into the latch at the angle of collision with the guide post of the downshift member. The guide post 6 is lowered by the guide post 6 of the slide member 60 so that the latch 30 can be stably inserted into the lowermost position. In the state shown in FIG. 10, the front end portion of the latch 3〇 of the zipper 1逆 and the front end portion of the tubular pin 40 are configured to have substantially the same position in the longitudinal direction of the reverse zipper. . Further, in the state shown in Fig. ,, the position of the front end of the latch 30 is lowered downward from the top (U-direction) top (the top of the meshing side) of the guide post 6〇〇 of the lowering member 6〇 to the latch. The position of the lower end position DP (D direction). By having the front end of the latch 30 located further below the guide post 6〇D of the lowering member 6〇 (the U direction slides the lower sliding member 60 from the lowermost end toward the upper side (U direction), the front end of the latch 30 can be easily The direction of the introduction port of the lowering member 6〇 is made. Therefore, the opening operation can be smoothly performed. Further, in the state where the lowering member 6 〇 and the latch 30 are at the lowermost end, the front end portion of the latch 3 成为 and the front end portion of the barrel pin become The state is hidden in the element guide passage 6〇τ of the slide member 60. The first and second elements 12 and 13 of the slide fastener 10 can be made of metal or resin, and the present invention can also be used for chain cloth. A coiled element such as a coiled element which is wound into a coil-like linear monofilament is sewn, and a fastener which can be generally used as a slide fastener can be used. INDUSTRIAL APPLICABILITY The present invention can be applied to both openable and reversed, It can be opened and detached from the inserted zipper. As such a reverse zipper, it can be used for opening and closing the left and right front of the jacket or coat, sportswear, and other purposes.
