Description

1379649 6. TECHNOLOGICAL FIELD OF THE INVENTION The present invention relates to a slider having a pull tab that is operated when opening and closing a slide fastener, and more particularly to a slider that can take a pull-down sheet when the slider is not in operation. [Prior Art] The slider on which the zipper is previously opened and closed is attached to the slider for the user to grip and move the slider. When the slider of the slider is placed on the slider body, the shaft portion of the slider is first inserted between the front and rear pillar portions of the slider body. Next, it is covered with a covering member to close the upper portion between the column portions, and the covering member is caulked to the column portion to form a bearing hole. Thus, by pulling the tab shaft portion into the bearing hole, the tab can be supported to be tilted with respect to the slider body. Moreover, in general, the slider body is not separated from the tab afterwards. However, if a part of clothes or purses are carried out, a temporary pull-tab is attached to the slide before the product is displayed on the storefront, and when it is sold, it is replaced with the use of the user's pull-tab, and the temporary pull-up is desired. Simply take down the situation. In addition, if the zipper is used in the locking portion of the seat cover of the automobile seat, once the binding and locking operation is performed, the pull tab is kept attached to the slider, and the slider and the pull piece are caused by the vibration during running. Continued collisions repeatedly produce *曰' so there is a case where the removal of the tab is preferable. Among them, a slider which can be removed by a pull tab is disclosed in Japanese Patent Publication No. 7-55161 (Patent Document No.) for the purpose of replacing a user's favorite pull tab. The upper surface of the slider body described in Patent Document 1 is provided with a tab mounting cymbal, and a bearing hole for accommodating the shaft portion of the tab is opened. The pull-up temple extends toward the rear end side of the α-piece body to form a rear end projection that closes the above-mentioned bearing 141134.doc 1379649. Between the upper end of the rear end and the slider body, a shaft portion of the slider can be formed: when the tab mounting rod is viewed from the side direction, the fishing rod has a shape of 3 in the rear of the slider body. The pull-tab is set to be: r_, which is arranged before and after the slider body = body == the closed body is formed with a sliding protrusion, and when the closing piece 1, the sliding protrusion of the closing body is given It can be stopped at the position opposite to the end projection of the pull=installation#, and the gap slip can be closed:::: When the slide body of the slider body is mounted, the first part of the slide body can be held/sliding. The sliding enclosure slides forward of the slider body to slide the enclosure. Thus, the sliding projection moves in the direction of the bearing hole. A gap portion is formed between the projection of the rear end of the tab mounting lever and the upper surface of the slider body to be inserted into the shaft portion of the tab. In this state, the tab portion is passed through in the open state portion, and the bearing hole is swam. Thereafter, by detaching the tab shaft portion above the bearing hole, the enclosure in front of the slider body is released from being free. In this manner, the sliding projection is biased to a position opposing the rear end projection of the tab mounting lever to close the gap. In the 6-squat state, since the gap portion is closed, the shaft portion of the pull-up X θ pull-up is not detached by the bearing hole. The slider described in Patent Document 1 can also be removed from the one-time mounted tab. However, when the pull-down piece is taken by the slider body, the slider body is first held, and a special metal-made tool with a thin front end is prepared to press the closing body to the front of the slider body to slide it. Thus, between the rear end projection portion 141134.doc / ^04^ of the tab mounting lever and the upper surface of the slider body, a gap portion through which the shaft portion of the tab is passed is opened. When the straw is maintained in this state, the pull shaft portion passes through the gap portion, and the slider body can take the pull-down piece. However, the 'work' requires three kinds of operations: the holding of the slider body at the same time, the pressing of the closing body to the slider body with a special tool, and the operation of taking the shaft portion of the drawing piece. It is difficult to carry out the work by hand. Therefore, the slider described in the patent document is used in exchange for the replacement: the temporary pull tab β is removed, and the end portion of the temporary pull tab is formed into a ring shape, and one of the % and the portion is formed. Cut off the fragile part. Further, when the clothes or the bags are sold, the temporary pull-tab is removed and replaced with the pull piece desired by the user, and the twisting operation of the slider body is performed by grasping the grip portion of the temporary pull-tab. In this way, the fragile portion of the shaft portion of the pull tab is first broken. When it is reversed, the temporary, κ grip. At the time of the break, the fragile part of the break will leave. Since the tab pull-out portion can be pulled out of the bearing hole by the opening-opening tab mounting lever, the temporary pull-tab can be easily and quickly removed from the slider body. Japanese Patent Publication No. 64-43706 (Patent Document 2) discloses a slider which is configured by detachably attaching and detaching a slider to a slider body. Patent Document 2 is incorporated. The loaded slider ′ is such that the tab portion of the tab has a shape that protrudes from the left and right sides, and a gap w is formed at the center portion. Further, the upper portion of the slider body is provided with a U-shaped tab mounting lever formed of a thin plate thinner than the gap w, and bearing holes are formed in both side walls. : When one piece is mounted on the π-piece body, insert one of the pull-tab shaft portions into the bearing hole of the side wall of the pair of women's clothing, and insert the part 141134.doc ^/9649 of the above-mentioned gap w into the pull-tab Install the side wall of one of the bars. Thereafter, the pull-tab is reversed as in the case of a nine-ring loop, and the pull-tab shaft portion on the opposite side is inserted into the bearing hole on the opposite side. Thus, the pull tab shaft portions on both sides can be inserted into the bearing holes opening toward the side walls of the pull tab mounting lever. Further, when the pull-down piece is taken by the slider body, it can be removed in the reverse order. Patent Document 1: 曰本特公平 7_5 5丨6丨

Patent Document 2: Japanese Laid-Open Patent Publication No. SHO-64-43 706. SUMMARY OF THE INVENTION PROBLEM TO BE SOLVED BY THE INVENTION The slider described in Document 1 can be used to twist the grip portion when the temporary pull tab is removed. Break the fragile part of the shaft of the pull tab. When the grip is continued, the grip of the pull tab will open the broken fragile portion, and the pull tab shaft can be driven by the bearing hole.

The temporary pull-tab of §1 contained in the literature 1 causes the deformation caused by the breaking of the fragile portion to the width of the pull-tab mounting rod, resulting in the potential shear stress and tensile stress applied to the (4) = shaft portion. Exceeding the maximum shear stress of the material ^large tensile stress', the possibility of breaking the wrist of the pull tab is the possibility that the nucleus of the puller shaft portion breaks when the fragile portion of the fragile portion and its other parts breaks Broken, will produce fragments that are separated by the break. Then, there is a problem that the operator takes time and effort in the recycling of the fragmented pieces. also. Preventing the slider from slipping due to the force applied to the '. ^ ^ on the pull tab, causing the tab to be over-produced, the sheet is made of high-rigidity material, or changed to a rigid shape. The annular part exerts a strong stress. This 14] I34.doc 1379649 will also contribute to the problem that the part other than the fragile part is also prone to breakage. Further, in the sliding member described in Patent Document 2, if the sliding sequence is performed by unwinding the nine-joint loop, but the movement and the reverse of the pull-tab are not performed, the pull-down piece cannot be taken, and the take-up of the pull-tab is time-consuming. problem. Such a tab that is difficult to remove, such as when transporting, etc., if the vibration is intermittently applied, the problem that the tab is naturally detached from the slider body is also generated. The present month is completed by the above problem, and the purpose of the present invention is to provide a T piece that can be pulled away from the shaft portion of the pull tab and the pull piece is removed from the slider body, even if it is tied In the case where the shaft portion is partially separated, the other portions of the tab can be prevented from being broken, thereby preventing the occurrence of fragments. The technical means for solving the problem is to solve the above problem. The sliding member for a zipper according to the present invention is characterized in that the slider body is a column portion having a bearing hole on which a cutting piece is formed to be tiltable; Pull the tab, 苴俜 ^ 71 ^ eight at the end has a pull-tab shaft inserted through the bearing hole, and the right cb, +, u 4 , has the end of the shaft portion of the upper slider The other end side is symmetrical with the left and right sides. a grip portion extending from the inside of the bearing hole; wherein the width of the column portion on the opposite inner surface of the bearing hole is Z, and the above-mentioned drawing is performed by the left-negative name of the above-mentioned (four) (four) (four) The protruding outer dimension of the ika X out part is set to mm, L ^ pn ^ Ββ. The interval between the above-mentioned locking protrusions, that is, the above-mentioned externally embedded ^ ^ m ^ u ^ a dry circumference is set as a tourist Z, and the above-mentioned wrists, and the wrists are set to a large internal size of j, and are satisfied with b>A>a, and j>z>z Η rm ^ xh λ, 4 4 The central portion of the above-mentioned swimming drink|& 2 forms an openable separation opening portion. (4) 141I34.doc 1379649 - and 'according to another invention', characterized in that the above-mentioned column portion width z, the inlaid range z, the wrist portion Between the maximum internal dimensions j, ζ<ΐ 5χζ,: j> 2xZ. According to another invention, the width of the wrist portion of the portion of the wrist having the largest internal dimension j is set to d respectively. Further, according to another invention, when the length of the wrist is set to 1, the length of the wrist is made such that the width of the wrist is equal to or less. Further, according to another aspect of the invention, the maximum internal dimension of the wrist portion is formed by the above-mentioned interaction opening and closing portion, and the fragile portion of the shaft portion of the left and right pull tabs is connected to the movable portion. The effect of the invention is that the column of the month/month piece that is erected on the upper side of the slider body has a bearing hole of the reference inner dimension of the branch piece to be poured, and the plug is connected to the above The both end sides of the tab shaft portion of the bearing hole are formed with a locking protrusion which is larger than the above-mentioned reference. The protruding outer dimension of the P dimension A is formed, and the interval between the locking projections is set. The spanning range is cumbersome to the width Z of the column body of the slider body, and is narrower than the maximum inner dimension 腕 of the wrist of the pull tab. And/the pull tab 1 is formed by the central portion of the wiping range 2 of the portion to form an interactive idle. Thereby, the tensile stress and the shear stress applied to the two wrist portions of the pull tab are substantially symmetrical when the pull tab is removed from the slider body, and the interactive opening and closing portion is opened away from the slider body. When the pull-down piece is taken, the hair can be reduced by applying a large stress to one of the wrists. The phenomenon of breaking and breaking. In addition, according to another invention, the gap between the locking projections is 141134.doc 1379649. The Zs history is defined as exceeding the width Z of the column and the width of the column.丨倍倍, and set the maximum internal dimension j of the wrist to be greater than 2 times the width of the column. Thereby, the shear stress applied to the two wrists can be made when the pull tab is removed from the slider body and twisted. The symmetry is close to this. When the separation opening portion is opened and the pull-down piece is taken out from the slider body, a large stress can be applied to one of the wrist portions to reduce the occurrence of breakage. Further, according to another invention, By setting the interval between the wrists to be more than three times the width z of the column portion, the interaction opening and closing portion is opened and the lowering piece is taken from the slider body, so that the shear stress applied to the wrist portion can be reduced, thereby reducing the wrist The bad phenomenon of breaking. According to another aspect of the invention, the wrist portion 1 is formed by 8 (mm) or more, the wrist width d is 1.2 (mm) or less, and the maximum internal dimension of the wrist is formed to be 7 (mm) or more. When the separation portion is opened and the pull-down piece is taken from the slider body, the shear stress applied to the wrist portion by the yoke can be reduced, thereby reducing the occurrence of breakage of the wrist portion. According to another aspect of the invention, the left and right tab shafts can be brokenly connected by the movable opening and closing portion, thereby reducing the problem that the slider body is detached from the slider body when the slider is slid by the strong operating force. . [Embodiment] A representative embodiment of the slider of the present invention will be specifically described with reference to the drawings. The figure is a plan view of the slider of the present invention as seen from above. Figure 2 is a plan view of a single piece of pull tab 59 mounted to the slider 50 of Figure 1. Fig. 3 is a front elevational view of the slider 5' shown in Fig. i as seen from the engaging opening side of the slider 50.

Further, the upper side of the slider 5 is defined as the direction of Fig. 3, and the lower side is defined as the direction D of Fig. 3. Furthermore, other drawings are also defined as the same direction. As shown in Figs. 1 and 3, the slider 5 of the present invention is composed of a slider body and a pull tab 59. A connecting post 50D is formed vertically upward (in the U direction of FIG. 3) from a central portion of the lower bottom flap 53 forming the slider body 5A, and an upper portion of the connecting post 50D is formed substantially opposite to the lower flap 53. The upper fins 52 are formed in parallel. On the upper surface of the upper flap 52, two front pillar portions 56F and a rear rake portion 5 6 R are respectively provided, four in total. The front pillar portion 561 and the rear pillar portion 56R of the slider main body 50A are four pillars that are vertically erected independently of each other, and are inserted in a state in which the tab shaft portion 59K formed at the central portion of one end of the tab 59 is inserted. The cover member 58 is placed at a special position of the front pillar portion 56F and the rear pillar portion 56R and is caulked to close the upper portion of the front pillar _56F and the rear pillar portion 56R. Further, a bearing hole 56 of an angular inner surface shape is formed, and the tab shaft portion 59K is swung therein, and the pull tab 59 is supported to be tilted. Flanges 50F are respectively provided upward from the left and right side edges of the flap 53 below the slider body 50A (in the direction of u in Fig. 3). Further, flanges FF are respectively provided from the left and right side edges of the upper fin 52 downward (in the direction of D in Fig. 3). The y-shaped space portion surrounded by the upper surface of the lower fin 53 and the left and right sides of the connecting post 50D, the lower surface of the upper flap 52, and the flange 50F allows the chain of the left and right links to be inserted. Through the chain guide path. A gap formed between the flanges 50F which are respectively erected by the left edge of the upper flap 52 and the lower flap 53 and the left edge of the lower flap 53 is a chain insertion passage through which the left and right chains of the zipper are inserted. The front side (the RS direction in the plan view of Fig. 1) of the connecting post 50D shown in Fig. 3 is formed in a tapered shape by a shape merged by right and left. When the fastener element row attached to the left and right sides of the zipper is inserted into the element guide passage, if the slider 50 is slid on the front side shown in FIG. 3 (the direction of rs in the plan view of FIG. 1), The chain of the left and right teeth in the engaged state is introduced by the opening of the slider 5 〇. Then, in the sprocket guide passage, the sprocket arranged in the center portion is used to separate the sprocket in the meshing state in the left-right direction, and the FS direction is shown in the plan view of FIG. ) The inlets of both sides are discharged. The inlet port refers to an opening surrounded by the side surface of the connecting post 5〇Ε>, the upper flap 52, and the lower flap 53. Further, when the slider 50 is slid on the inner side as shown in Fig. 3 (the FS direction in the plan view of Fig. 3), the sprocket line in the separated state is introduced from the introduction port of both of the sliders, and the left and right chains are The tooth rows are guided and merged along the flanges 5〇F, and are engaged, and are discharged from the engagement opening of the slider 50 on the front side (the RS direction in the plan view) shown in FIG. As shown in FIG. 1 to FIG. 3, a central portion of one end of the pull-tab 59 which is fitted upstream of the slider 50 is formed with a tab shaft portion 59K inserted through the bearing hole 56A, and is formed on both sides of the tab shaft 59Κ. The end portion is formed with a pair of locking projections that are not symmetrical in the size of the bearing hole, and the two sides of the Haika stopper projection 59 are extended to the other end side of the pull tab 59. 〇Α, 〇Α, Β There is a right and left symmetrical wrist on the extended wrist 5 9 Α another Qiu Ba Zhiqiu Qiu. The 鸲邛 division forms a flat grip.卩 ‘The heart of the system allows the system to hold (4) the fingers of the heart. 141134.doc •12- Another one shown in Figs. 1 to 3 is only a %-shaped filter, and an opening having a rectangular shape in plan view is formed in the grip portion of the pull-tab 59. As shown in Fig. 1, the reference internal dimension of the inner surface of the bearing hole 56 of the upper portion of the slider body 5 is defined as Α ' the column of the front pillar portion and the rear pillar portion. The p width is defined as z. Moreover, the width of the κ part of the pull-tab shaft portion is outside. The P-size is a, and the two ends of the pull-tab shaft portion are fixed to the left and the other are - they are locked. The protrusion P dimension of the width of the portion of the protrusion 59H is bb. The distance between the locking protrusions 59H and the outer dimension a is defined as the range B, the wrist The maximum internal dimension of the wrist portion of each of the portions 59A is defined as "the width of the wrist portion 59A of the portion of the maximum internal dimension j of the wrist is defined as d, and the wrist interval between the left and right wrist portions 59A is defined as n. In addition, in the embodiment shown in Figs. 2, 6, 7, 8, and 10, the cross-sectional shape of the arm portion 59α is circular, but the cross-sectional shape of the arm portion 59 is not limited to a circular shape, and an elliptical shape may be used. The cross-section, the rectangular cross-section, and other cross-sectional shapes. The present invention stipulates that the outer dimension & of the tab shaft portion 59 is set to be smaller than the reference inner dimension A of the opposite inward plane of the bearing hole 56A, and the swath range z It is set to be larger than the column portion 56ρι of the column body 56ρι and the rear pillar portion before the slider body 5A. The pull tab shaft portion 59κ can be fitted into the bearing hole 56a, and the pull tab 59 can be supported to be tilted in the front and rear directions of the slider body 5A. Further, by the pair of left and right tabs of the pull tab 59 The portion of the portion 59H is protruded. The P dimension b § is further greater than the reference inner dimension A of the opposite inward faces of the bearing hole 526 A, which prevents the bearing hole 56A from being set to be larger than the play range z.

The portion of the wrist having the largest internal dimension j causes the tab 59 to rotate substantially along the bearing hole 56A of the slider body 5A I41I34.doc • 13· 1379649. Further, since the column portion 56F and the rear column portion 56r are sandwiched between the locking projections 59H formed at the both end portions of the tab shaft portion 59K, the interleaving portion 59B can be always held at The central portion of the bearing hole 56A. Accordingly, when the user pulls the pull-tab 59 from the slider main body 5A and performs the twisting operation on the pull-tab, the user can uniformly maintain the deflection and twist of the left and right wrist portions 59A. When the pull-down piece 59 is taken in 50A, the tensile stress and the shear stress applied to the right and left wrist portions 59A are equalized, and the problem that the wrist portion 59A is broken by the excessive stress applied to only one of the wrist portions 59A can be reduced. Therefore, it is preferable to set the wiping range z to be less than 5 times the column width Zii. Further, the central portion of the wiping portion 2 of the tab shaft portion 59K is formed with an interactive opening and closing portion 59B that can be alternately opened and closed. In the embodiment shown in Fig. 2, the left and right tab shaft portions 59K are connected to each other in the interactive opening and closing portion 59B, and the cross-sectional area of the portion forming the interlacing opening portion 59 is formed to be much smaller than the sectional area of the tab shaft portion 59κ. For example, when the outer dimension a of the tab shaft portion 59 is set to an outer dimension of 0.8 (mm), the outer dimension of the interleaving portion 59B can be set to about 0.3 (mm) to 0.4 (mm). Thus, the portion of the alternating opening and closing portion 59B is formed by the thinner and smaller sectional area, in the pair of slider body 50. When the pull piece 59 is subjected to the twisting operation, the pull piece 59 can be removed from the slider body 50A by first breaking the portion of the interactive opening portion 59B, and then continuing to twist the pull piece 59'. Since the left and right tab shaft portions 59κ are connected to each other in the initial state in the interactive opening and closing portion 59B, even if the slider 5 is slid with a strong operating force, the tab 59 can be reduced from being detached from the slider body 50A. 141134.doc 1379649 _ For example, it is intended to cover the opening formed on the surface of a car seat or a seat cover such as leather, and is used in the case of a zipper. The interior of the car seat is used. The seat spring or the cushioning material is accommodated, and the seat cover is pressed against the members of the elastic body without causing the surface to be sensitive. At this time, a large tension is applied to the seat cover. Assembly steps of the alpha vehicle seat In the middle of the 'pad cover material, the cover is covered by the cushion material, and when the separate zipper is closed, the zipper is closed while the slider 5 is slid, and the zipper material is compressed while closing the zipper. In this case, it is necessary to The slider 5 〇 exerts a force of about 15 kgf It is slid to resist the force of the compression cushion material. To ensure the operability at this time, it is preferable to form the slider 59 of the slider 50 to make it easy to grasp, and to enhance the interaction opening to some extent. The breaking strength of the °P59B is to prevent the pull-tab 59 from coming off the slider body 50A when the force is applied during the operation. When the zipper is used in the opening of the seat cover of the automobile seat, once the opening of the seat cover is closed After the work, the pull-down piece 59 can also be taken. If the slider body 50A is attached to the slider 59, the slider body 50A and the pull-tab 59 are intermittently repeatedly collided by the vibration during running to generate noise. To prevent this noise from occurring, it is sometimes preferable to remove the pull tab 59 from the slider body 50A after closing the seat cover. As shown in FIG. 1 to FIG. 3, the cross member 59B is formed to be frangibly connected to the fragile portions of the left and right tab shaft portions 59κ, so that the necessary sliding members can be sufficiently used in normal use. When the force is applied and the tab 59 is removed from the slider body 5, it can be simply removed from the slider body 50 by twisting the tab 59. 141134.doc •15· 1379649 Further, by setting the maximum internal dimension j of the wrists 59A to each other to be larger than the interval z of the interval between the locking projections 59H, the twisting of the opposite slider body 50A can be reduced. The sheet 59 causes the operation force necessary for the breakaway portion 59B to be broken. And the operation force at the time of continuously twisting the tab 59 can be reduced, and the pull-down 59 can be easily taken from the slider body 5A. Further, by setting the maximum internal dimension j of the wrist to a large extent, the interactive opening portion 59B can be opened to the column width z by a small twist angle. Thereby, the tab 59 can be easily removed from the slider body 50A, and excessive stress can be prevented from being applied to the wrist portion 59A to reduce the breakage of the wrist portion 59A. In particular, it is preferable to set the maximum internal dimension j of the wrist to be more than twice the width Z of the column portion, and it is preferable to set the width of the wrist portion 5 9 A of the portion of the maximum internal dimension j of the wrist to d. 'The maximum internal dimensions of the wrist' plus the width of the wrist is set to be more than three times the width Z of the column. That is, it is preferable to set the wrist width d as small as possible and to set the maximum inner dimension j of the wrist as much as possible in a range capable of withstanding the force applied when the slider 50 is slid. The length of the pull tab 59 which is generally easy to use is about 2 〇 (mm) to 30 (mm). Further, the column width Z is generally about 2.5 (mm) to 3 (mm). Therefore, when the length of the wrist portion 59A is set to 1, it is preferable that the wrist length 丨 is "1 (4) or more, the wrist width d is 1.2 (mm) or less, and the maximum internal dimension of the wrist is j47 (mm) or more. Next, the state in which the tab 59 is rotated along the bearing hole 56A of the slider body 50A will be described with reference to Figs. 4 and 5. Fig. 4 is such that the latching projection 59H abuts when the tab 59 is rotated in the horizontal plane of the slide fastener. A plan view of the side of the rear pillar portion 56R restricting the rotation of the tab 59. Fig. 5 is a state in which the tab 59 is abutted against the cover when the tab 59 is rotated in the plane of the vertical 141134.doc -16· of the zipper. The side wall of the member 58 is a view for restricting the state of the rotation of the tab 59. The same members as those described with reference to Figs. 1 to 3 are denoted by the same reference numerals and the description thereof will be omitted. It is preferable to form the pull tab 59 by being rotatable to the position shown in Figures 4 and 5. However, if the progressive rotation of the pull tab 59 is allowed, the interactive opening portion 59B of the pull tab 59 will be from the front pillar portion. The central portion of the 56ρ and the rear pillar 4 56R is largely deviated, so that the user pulls the pull-down month 59 from the slider body 50A. When the sheet 59 is twisted, the amount of deflection of the left and right wrist portions 59A may be generated, or a difference may occur in the twist angle. If the amount of deflection or the twist angle between the left and right wrist portions 59A is different, the wrist portion is larger in deflection. 59A is applied with a tensile stress greater than the maximum tensile stress, and the shear stress above the maximum shear stress is applied to the relatively twisted wrist portion 59, so that the possibility of breaking the wrist portion 59A is increased. Preferably, the interval between the left and right locking projections 59H is set as small as possible within a range in which the operability is deteriorated when the slider 50 is not slid. The relative orientation is described later with reference to FIGS. 6 to 8. The process of the slider body 5A is reversed when the pull-down piece 59 is taken. Fig. 6 is a view showing the shearing force WK applied to the interactive opening and closing portion 59B when the pull-tab 59 is vertically erected on the slider 5A in the clockwise direction. Fig. 7 is a plan sectional view showing a state in which the alternating opening and closing portion 59B is broken in the state shown in Fig. 6 to further twist the tab 59 in the clockwise direction. Fig. 8 is a view showing the slides up to the slider. The plane in which the body 5〇A takes the pull-down piece 59 and twists the state of the pull-tab 59 Fig. 6 to Fig. 8 are plan cross-sectional views showing the slider body 5A in the center portion of the front pillar portion 56F and the rear pillar portion 56R. Further, the pull tab 59 is shown on the wrist I41I34-1010822. .doc 17 1379649 When the size 5 is set to 〇3 (mm) to 〇.4 (mm), even if a sliding force of about 15 (kgf) is applied to slide the slider 50, it will not be found only by the sliding motion. The sign that the interactive opening and closing portion 59B is broken.

If the interactive opening and closing portion 59B is broken in the state shown in Fig. 6, it will become a state in which the interactive opening and closing portion 59B is alternately opened and separated as shown in Fig. 7 . Further, if the pull tab 59 is further twisted in the clockwise direction, as shown in FIG. 8, the left and right interactive opening and closing portions 59B will protrude from the outer side of the slider body 5's bearing hole 56A, and the pull tab 59 can be slid. The body 5〇a is removed. As shown in Fig. 8, the grip portion of the pull-tab 59, which can be removed from the slider body 5A, is rotated to the position where the pull-tab removal position 59τ is rotated. However, the handle shaft portion 59 is in a state of emulating the side walls of the front pillar portion 56F and the rear pillar portion 56R in accordance with the torsion and deflection generated by the wrist portion 59 (see Fig. 6). It is assumed that the torsion angle of the wrist portion 59A is 0a at this time, and the amount of deflection of the wrist portion 59A is Va. If the amount of the wrist deflection amount Va is applied to the wrist portion 59A, the tensile stress is aa' and the wrist is applied. When the shear stress applied to the arm portion 59a in the case of the torsion angle @a is Ta, the tensile stress (ja and the shear stress Ta can be calculated by the following formula. The cross-sectional shape of the wrist portion 59A is assumed to be the circle of the diameter d Shape, and set the length of the wrist 59A to

Then, the allowable wrist twist angle @a is calculated by the above (Formula 11). Here, for the die casting When the allowable shear stress Ta=265 (MPa) of the alloy (ZDC1) and the shear modulus of elasticity G=22 (GPa), the allowable wrist twist angles 0a and 〇.3 can be calculated by the above (Formula 11). Rad). In addition, the wrist twist angle is equivalent to I7.3 (deg). As shown in Figure 8, 'even the left and right wrists 59A In the case of deflection to the wrist deflection amount Va and 0'3 (mm), the left and right tab shaft portions 59K are spaced apart from each other only to 2xVa><Cos©a=?0_57(mm). Usually, generally Since the column width 设定 is set to a size of about 2.5 (mm), if any of the tab shaft portions 59K are to be spaced apart from each other by the width z of the column portion only depending on the deflection of the wrist portion 59A, any wrist portion 59 must be made. A is broken, and the fragment is separated according to the break. Therefore, as shown in Fig. 8, if nxSinQa is calculated by the wrist spacing n=i〇(mm) and the wrist twist angle and 0.3 (rad), nxSin0a can be obtained. With 3.0 (mm). Therefore, the opening amount of the left and right pull tab shaft portions 59K is 141134.doc • 20-1379649 2xVaxC〇S0a+nxSin0a and 3.57 (mm), because Z+d=2.5(mm)+0.8 is exceeded. (mm) = 3.3 (mm) 'The pull tab 59 can be removed from the slider body 50A without breaking the wrist portion 59A of the pull tab 59. Fig. 9 shows the pull taken from the slider body 5A. A perspective view of the appearance of the sheet 59. As shown in Fig. 9, since the wrist spacing η is set larger than the previous pull tab 59, the wrist can be reduced even when the interactive opening portion 59 is opened. 59 Α breaks Undesirable phenomena. The dimensions of the above, by setting the longer arm length 1 can be increased left and right arm portions 59A of the opening amount. Further, the opening amount of the left and right wrist portions 59A can be increased by setting the wrist width d smaller. However, since both of the above are highly likely to reduce the strength necessary for operating the tab 59, it is difficult to use it for the necessity of performing a strong sliding operation on the slider 50. In contrast to this, the wrist interval η is independent of the strength of the pull tab 59, so that the wrist interval η can be set large without affecting the sliding operation. Therefore, in the present invention, the wrist spacing η is set large, and the locking protrusions are formed on the both end portions of the tab shaft portion 59Κ in order to prevent the disadvantage of the S-shaped wrist portion spacing η from being set by a larger %. 59Η, and an intermediate opening portion 59Β is formed at a central portion of the tab shaft portion 59Κ. Thereby, the tensile stress and the shear stress applied to the right and left wrist portions 59 when the pull tab 59 is twisted can be symmetrically approached. Thereby, when the interleaving opening portion 59 is opened and the slider body is taken down, the lower portion of the arm portion 59 can be reduced to cause a large stress to cause a breakage. Next, a case where the slider piece 5p' having a small arm gap np is attached to the slider body 5A and the slider piece 59p is twisted with respect to the slider body 50A will be described with reference to FIG. Figure 141134.doc •21 · 1379649 ίο is a plan sectional view illustrating the case where the twist is removed from the slider body 50 and the pull-tab 59p is removed from the position 59Τρ, and the slider body is 5〇a on the front pillar A plan cross-sectional view of the central portion of the portion 56F and the rear pillar portion 56R is cut. The pull piece 5 9p ' is shown in the cross section of the wrist cut at the wrist interval np. In addition, the same members as those described with reference to FIG. 1 are given the same reference numerals, and the description thereof is omitted. If the torque is reversed to the position where the pull-off piece 59p can be taken from the slider body 50A, the same as FIG. In comparison with the case, the wrist deflection amount Vp and the wrist torsion angle Θρ are excessively increased, so that the stress applied to the wrist portion of the pull tab 59p exceeds the breaking valley final stress. Thereafter, the wrist of the pull tab 59p is broken. Fig. 11 shows a state in which the wrist portion of the pull piece 59p is broken. As shown in Fig. ,, the wrist of the pull piece 59p is broken near the root of the wrist according to the tensile stress caused by the deflection or the shear stress caused by the twist. Next, another embodiment of the shape of the slider attached to the slider and the shape of the vicinity of the tab shaft portion 59 is described with reference to Figs. 12 and 13 . Fig. 12 is a view showing an embodiment in which the cross-sectional area which is increased by the presence of the locking projection 59 is reduced, and the notch portion 59R is formed on the opposite side of the locking projection 59 of the tab 159. Fig. 13 is a view showing an embodiment in which the left and right tab shaft portions 59K of the tab 259 are not connected to each other to form the non-joining portion 59S. As shown in Fig. 12, by forming the notch portion 59R on the opposite side of the locking projection 59, the cross-sectional area which is increased by the presence of the locking projection 59 is reduced. Thereby, when the pull tab 159 is twisted and pulled out from the slider body 5, in addition to the deflection and twist of the wrist portion 59A of the pull tab 159, it is easy to cause the locking portion 59H to flex, which can be increased. The left and right pull tab shaft portions 59κ are opened to each other 141134.doc -22· 1379649. When the torsion tab 159 is removed and the slider body 5A is removed, the problem that the wrist portion 59A is broken can be reduced.

Further, as shown in Fig. 13, a gap (non-coupling portion 59S) may be formed between the tab shaft portions 59K on the right and left sides of the tab 259. By connecting the right and left tab shaft portions 59K as shown in Fig. 2, it is possible to withstand the force applied to the tab when the slider is slid. However, in the case where the slider is not required to be used too much, as shown in Fig. 13, a non-joining portion 59S may be formed between the right and left tab portions 59K. INDUSTRIAL APPLICABILITY The slide fastener of the sliding member of the present invention can be used for the latching of the seat cover of an automobile seat, and can also be used for the locking of the cover material of the armrest, and the opening and closing of the clothing or the tent and other articles. Use. Further, in the above-described embodiment, an embodiment in which a zinc alloy for a die-casting material is used as a material of La # is shown. However, the present invention does not limit the material to the word of the word, and may use white copper, brass, and other metals. Synthetic resins can also be used.
