Patent Document 1: Japanese Laid-Open Patent Publication No. Hei. No. 2006-468. Patent Document 2: JP-A-2008-43568 SUMMARY OF THE INVENTION Problems to be Solved by the Invention Regarding a zipper 'generally, it is desirable that the meshing strength Preferably, when the left and right element rows are in meshing state, for example, even if they are subjected to a lateral pulling force such as pulling the left and right zipper chain cloth outward along the width direction of the chain cloth, the left and right key rows are It will not separate but will maintain a stable state of stability. In the above-described Patent Document 1, the zipper of the sprocket row is formed by the continuous sprocket 55 of the coil shape or the continuous sprocket of the zigzag shape, and is made of, for example, a synthetic resin as described in Patent Document 2 above. The sprocket 64 is more flexible than the zipper of the sprocket row on the front and back sides of the zipper chain. However, in the pull key 51 in which the continuous fastener element 55 is mounted as described in Patent Document 1, the fastener element row is formed only on one side of the fastener fabric. Therefore, if the sprocket row or the detaching insert of the zipper 51 is subjected to the upper floor force, the relative position of the pin 52 and the pin 53 is offset in the direction of the front and back of the chain cloth, even when the element rows are engaged. The insertion portion 52d of the latch 52 is inserted between the upper and lower leg portions 5 5b of the key stomach. The insertion portion 52d also deviates from the element 55, and 140938.doc -10- 201029596 is easy to open from the side of the fastener element. The ends are de-chained. On the other hand, the separate sprocket 64 made of the synthetic resin described in the above Patent Document 2 is symmetrically provided on the front and back of the pull key cloth, even if the key row or the open insert is subjected to the upper urging force, Any portion of the surface side or the back side v of each of the fastener elements interferes with the fastener element on the side of the engagement target, whereby the meshing state of the fastener element row can be maintained, so that the occurrence of the chain breakage can be suppressed. Therefore, the zipper 51 in which the continuous key teeth 55 are attached as described in Patent Document 1 has a drawback in that it is relatively strong on the upper floor as compared with the case where the zipper 51 of the sprocket is arranged on the back surface of the key sheet described in the above Patent Document 2. The strength is low. In particular, for example, in the zipper in which the sprocket row is formed by a coil-shaped or serrated continuous sprocket, as the detachment insert, the detachable insert excellent in operability disclosed in the above Patent Document 2 is used, that is, When the insert body and the pivoting support body are arbitrarily selectable for the lateral insertion locking operation and the usual locking operation of the opening and closing insert, there is an extremely weak strength for the supporting force toward the opening and closing of the insert. Specifically, in the open-release insert 62 described in the above Patent Document 2, the thickness of the inserting plate portion 67a of the inserting body 67 is formed thin as described above. Therefore, there is a drawback that the inserting plate portion 67a is easily bent or easily deformed when the opening and closing insert 62 is supported by the back and forth of the fastener, so that the position of the embedded body 67 is easily displaced. Therefore, the side opening type opening and closing plug-in described in the above Patent Document 2 is used with respect to the pull key of the continuous key tooth having a coil shape or a mineral tooth shape having a salivation strength lower than that of the individual key teeth of the synthetic resin. In the case, when the key row or the open insert is subjected to the selection force, it is easy to cause the chain to be disconnected from the end of the insert side of the chain insertion 140938.doc 11 201029596. Therefore, in order to commercialize such a zipper, it is required to increase the meshing strength of the insert body (pin) of the element row and the end portion of the tumbling support body (cylinder pin) side, and it is particularly required to increase the strength against the upper struts. The present invention has been made in view of the above-described prior problems, and a specific object thereof is to provide a zipper which is formed of a coil-shaped or zigzag-shaped sprocket, so that the flexibility is excellent, and the pin and the barrel of the sprocket row are arranged. The meshing strength at the pin-side end portion is improved, and the chain element row can be prevented from being de-chained even if the opening and closing of the insert is subjected to the upper force. Technical Solution to Problem In order to achieve the above object, the most important feature of the basic structure of the zipper provided by the present invention is that it is formed on the side edges of the respective left and right zipper chains to form a chain of teeth. a pair of left and right chain belts, a cylinder pin having at least one end portion of the chain element row attached to the left and right sides, and an opening and closing insert of the bolt, and a slide fastener for engaging and separating the left and right fastener element rows, the chain The tooth row is formed by a coiled or serrated continuous element forming the pin disposed on one of the fastener tapes or the first pin having the hook shape, and the first hook portion of the hook is spanned The front surface of the zipper chain is integrally formed on the side of the sprocket side of the pin or the pin, and is disposed between the pin or the pin and the chain-tooth row disposed on the other chain.

Rotating, thereby inserting the pin body portion 11a of the latch 11 into the lower side guide 140938.doc • 25· 201029596 8d above the slider 8. At this time, 'until the pin u abuts the connecting post of the slider 8' or The latch ^ is rotated until the position near the connecting post 8c. Thereby, the relative position of the latch 11 and the pin 12 can be set to a state in which the meshing of the element rows 2 shown in Fig. 5 can be stably started. On the other hand, 'as a second operation method', the shaft portion 11b of the plug pin is inserted from the shoulder portion of the slider 8 and guided through the sprocket guide passage 8h of the slider 8, whereby the pivot support portion 12c can be made. The shaft portion 11b is pivotally supported. Thereby, the position where the latch u and the cylinder pin 12 are opposed can be set in a state in which the splint row 2 can be stably started in the same manner as the above-described first operation method. _ After the relative position of the latch 11 and the pin 12 is set to a specific state, the slider 8 is slid toward the sprocket meshing direction, that is, forward. In this way, make the butterfly hold. The first hook portion 11c is engaged with the second hook portion of the engaging reinforcing member 9 and the engaging projection 9c of the engaging reinforcing member 9 is inserted into the upper sprocket 5a adjacent to the engaging object side of the latch 丨Thereby, the engaging projection 9c is engaged with the second sprocket 5a. At this time, the engaging reinforcing member 9 is formed independently from the tubular pin 12, so that the sliding resisting force of the slider 8 can be prevented, and the engaging reinforcing member 9 can be easily inserted from the ... and the i-th teeth 5a. Hehe. Further, the i-th hook portion of the latch n and the second hook portion 9b' of the spray-bonding reinforcing member 9 are formed such that the dimension in the longitudinal direction of the key cloth is larger than the respective fastener elements 5°. Therefore, even when the slider 8 is slid, even the plug U It is disposed at a position slightly offset from the cylindrical pin 12, and the i-th hook portion 2 can easily be engaged with the fishing portion 9b, so that the operability (startability) at the start of sliding of the slider 8 can be greatly improved. Then, the slider 8 is then further slid forward, whereby the left and right element rows 2 are sequentially engaged from the first key 140938.doc • 26 - 201029596 5a, so that the zipper 1 can be easily closed. In the zipper 1 of the first embodiment which is closed in this manner, as shown in Fig. 6, the first hook portion 11 (between the engaging reinforcing member 9 and the slider holding portion 12a of the pin 12) is further described above. The hook portion 11C is located above the sprocket side end portion of the slider holding portion 12a. Further, the second hook portion 9b of the engagement urging member 9 is firmly engaged with the first fishing portion 11c' of the latch 11 and is reinforced. The engaging projection 9c of the member 9 is firmly engaged with the first sprocket 5a adjacent to the latch 11. Therefore, the flexibility of the key row 2 is not hindered, and the opening and detaching of the sprocket 2 can be greatly improved. Engagement strength in the end portion of the 10th side. Further, when the left and right key row 2 of the first embodiment are in the engaged state, even if the fastener chain 4 is pulled outward in the width direction of the chain, the fastener element is made. Row 2 (especially the end of the sprocket row 2 away from the side of the insert 1) is subjected to a transverse pulling force 'again' even if the sprocket row 2 or the detachment of the insert 10 is supported by the back of the chain back. The lateral tension and the upper supporting force can be effectively alleviated by the engagement of the engaging reinforcing member 9 with the first hook portion UcW ❺ and the first key portion 5a, thereby preventing The end of the opening of the key row 2 is separated from the end of the side of the insert 1 . Specifically, the description is made in the above-mentioned zipper 1 'for example, when the sprocket 2 is subjected to the lateral pulling force in the width direction of the chain fabric, then FIG. 7 As shown, the ringing reinforcing member 9 is moved in a direction in which it is disengaged from the engagement with the first hook portion 11c. However, on the other hand, the side of the pin 12 on which the first hook portion 11c is fitted into the recess lie is formed to be close to The inclined surface of the zipper chain 4 having the tubular pin 12 inclined toward the sprocket row 2 makes the second hook portion 9b embedded in the fitting recess lie have an inclined surface corresponding to the inclined surface of the fitting recess lie, and therefore, the engaging reinforcing member 9 will move to the side of the element row 2 along the inclined surface such as 140938.doc -27-201029596. Therefore, the engaging protrusion 9c of the engaging reinforcing member 9 will be inserted deeper into the lower leg of the first element 5a. Therefore, the meshing reinforcing member 9 interferes with the first sprocket 5a. Thereby, the movement of the engaging elastic member 9 is hindered, so that the second weir portion 9b of the engaging reinforcing member 9 and the first hook portion iic of the latch 11 can be prevented. The snapping is disengaged, and the engaging projection 9c of the salivating reinforcing member 9 can be made stronger with the first sprocket 5a. Therefore, even if the element row 2 receives a lateral pulling force, the engagement of the mouth reinforcing member 9 with the pin U and the first element 5a will not be disengaged, so that the opening of the element row 2 can be prevented. The end portion of the insert 1 is unchained. In the above zipper 1, when the element row 2 or the opening insert 1 is supported by the back of the chain cloth, the opening of the element row 2 The joint strength of the end portion of the side of the insert 1 is increased, and since the second hook portion 11c of the latch and the second hook portion 9b of the joint reinforcement member 9 are both straddle the back surface of the key sheet of the zipper key cloth 4. In this case, the engagement state can be maintained by mutual interference of any of the front side or the back side of the first hook portion 11c and the second hook portion 9b. Further, even if the positional relationship between the first hook portion Uc and the second hook portion is shifted in the front and back directions of the key cloth due to the upper supporting force, the first hook portion Uc and the second jaw portion 9b are horizontally crossed. It is formed so as to extend across the back surface of the key sheet, and the engagement between the first hook portion Ue and the second hook portion 9b is not easily released. Therefore, even if the element row 2 or the detaching insert 10 is subjected to the upper urging force, the detachment of the end portion of the element row 2 from the side of the insert 10 can be effectively prevented. In particular, in the zipper 1 of the first embodiment, when the left and right element rows 2 are engaged, the protruding piece i2g formed on the slider holding portion i2a of the dowel 12 overlaps the upper side ' of the pin 11' and engages the reinforcing member 9 The recessed portion 11d formed by the lower side of the plug 11 is fitted into the notch portion Ilf formed by the first hook portion lie of the latch 11 by the projection portion 9938.doc • 28· 201029596. Therefore, when the latch 11 that is opened from the insert 10 is pushed upward by, for example, from the lower side thereof, the projecting piece I2g formed on the slider holding portion 12a will abut against the latch 11 from the upper side, preventing the latch 11 from being pulled. The position of the pin 丨 2 is offset, so that the sprocket row 2 can be prevented from being decoupled more reliably. On the other hand, when the latch 开 is opened from the side of the insert 1

When the upper pressing force is pushed down, the fitting protrusion 9d of the engaging reinforcing member 9 abuts against the first hook portion lie from the lower side, thereby preventing the position of the pin ^ from being displaced with respect to the pin 12, so that the element can be more reliably prevented. Row 2 produces a chain. In order to open the zipper 1, by sliding the slider 8 rearward, the meshing teeth 5 are pulled apart to abut against the boring of the section of the pivotal support body 12c. In this state, as shown in Fig. 4, the meshing of the fastener elements 5 is separated, and the engagement between the first fishing portion He and the second hook portion 9b is also released. At this time, the first! The hook portion lie and the second hook portion 9b sandwich the connecting portion of the slider 8 to be divided into right and left. Then, the latch η is moved 'to disengage the shaft portion Ub of the above-mentioned insertion (4) from the pivoting space 12h of the tubular pin 12, whereby the latch u can be separated from the tubular pin 12.
