As shown in Figure 1, the inside of head main body 7 is being drawn to be formed with chain tooth path 71. More specifically, the chain tooth path 71 being formed in head main body 7 and running through along the longitudinal direction is being drawn. Although not shown, but the rear portion of chain tooth path 71 is straight line shape, and the front portion of chain tooth path 71 is branch into the state of two strands towards front. That is, chain tooth path 71 is in Y font, and at the rear portion of chain tooth path 71, chain tooth 4a, 4a are passed through by one with the state engaged, and in the front portion of chain tooth path 71, the state that chain denture 4,4 is separated with left and right is passed through by one. In addition, the lower surface of head main body 7 is being drawn to be formed trough of belt (not shown) that chain tooth path 71 is connected with outside space. The bottom of one pair of band joggling part 32,32, through trough of belt, thus, is drawing the lower section configuration one of head main body 7 to band main body portion 31,31. In addition, drawing head main body 7 to have the upper flange 72 covered above chain tooth path 71, this upper flange 72 forms the top drawing head main body 7.With the lower portion of upper flange 72, namely draw the upper and lower of head main body 7 to compared with centre portion and bottom, the front portion of upper flange 72 is outstanding to front, and with the upper surface of stopper body 51.

Draw the upper and lower of left and right side of head main body 7 to centre portion, have one highlightedly to side to supporting axle 8,8. One pair of supporting axle 8,8 is configured to a straight line along left and right. As shown in Figure 3, the formation supporting axle 8 comprises the flange part 82 outstanding to the outer circumferential side in axle main body portion 81 along the axle main body portion 81 of left and right extension and the leading section, direction, left and right from axle main body portion 81.

Draw and climb 9 and have: be bearing in one on supporting axle 8,8 and can link and release the framework 91 of link relative to stop part 5; With with relative to framework 91 to the grip part 94 fixing with a state that the contrary side of supporting axle 8,8 is extended.

Framework 91 is U-shaped, has a parallel left right vertical frame 92,92 and horizontal frame 93 that the one end by left right vertical frame 92,92 is engaged with each other, and supporting axle 8,8 is linked by the other end of left right vertical frame 92,92 and. The left interval 92w of right vertical frame 92,92 is roughly consistent with the width dimensions 51w in the direction, left and right of stopper body 51. Framework 91 is rigid body, such as, be metal, by elongated metal bar is flexed into U-shaped and further the both ends of metal bar are flexed into C font respectively and are made hook. Then, the outer circumferential side in axle main body portion 81 interted by the hook at these both ends to supporting axle 8, thus supporting axle 8,8 by supporting and can be rotated centered by supporting axle 8,8 by one by framework 91 relative to one. In addition, the color of the framework 91 of present embodiment is and stop part 5 distinct colors, such as, be golden, but can also be formed by the color identical with stop part 5.

Grip part 94 is soft ribbon, is fixed on by ribbon on horizontal frame 93. 6 are drawn to move by pulling this grip part 94 and making with finger. In addition, make to draw 6 advance and collide with stop part 5, then become the state that one pair of chain denture 4,4 is engaged, on this basis, by pushing away into framework 91 together with this grip part 94, and make framework 91 by one to rotating centered by supporting axle 8,8, and surround left and right side and these three faces of front surface of stopper body 51 in U-shaped by framework 91. It is stop part 5 and draw the connecting state climbing 9 in the state making framework 91 surround above-mentioned three faces making one pair of chain denture 4,4 engage simultaneously like this. And, in order to keep this connecting state, in this enforcement mode, the left and right sides as two selection faces in above-mentioned three faces of stopper body 51 are formed with left and right projection 53,53. More specifically, on the face, right side and face, left side of stopper body 51, from overlooking direction and main apparent direction is symmetrically formed with left and right projection 53,53, in downside compared with projection 53 in stopper body 51, it is formed with the part surrounded by framework 91. In the example in the figures, left and right projection 53,53 is formed in the face, right side of stopper body 51 and the top in face, left side, and the upper and lower in stopper body 51 is formed with the part surrounded by framework 91 to centre portion and bottom.

As shown in Figure 6, each projection 53 is formed in the front portion of stopper body 51 when side-looking. If changing visual angle at top view stop part 5, then in a part for the total length on the limit that each projection 53 is formed in the situation of overlooking to be formed by the face being extruded with projection 53 in above-mentioned three faces.In other words, as shown in Figure 2, projection 53 relative to the forming position of stopper body 51 it may be said that be the part of the total length (the total length L1 on the left side and the right) on each limit formed by the left and right side of stopper body 51, the more specifically front portion of the length direction of total length L1. And, the total length of projection 53 is formed as each limit formed by the left and right side of stopper body 51 total length (the total length L1 on the left side and the right) more than 1/4 and less than 1/2.

In addition, as shown in Figure 7, the side of each projection 53 becomes the scarp 53s that outside in the lateral direction is stretched out along with trend lower section. More specifically, the face, left side of left side projection 53 is the scarp 53s at regulation angle of inclination towards left side gradually along with trend lower section in the scope except its upper and lower end parts; Right side projection 53 face, right side also become in the scope except its upper and lower end parts except along with trend lower section and gradually towards right side be regulation angle of inclination scarp 53s. And, the corner between the upper end of the side of each projection 53 and the upper surface of each projection 53 implements chamfering. Equally, corner between the bottom of the side of each projection 53 and the lower surface of each projection 53 also implements chamfering. These corners become the curved surface of the circular arc shape that drum goes out laterally.

Greatest width dimension 53w (hereinafter referred to as " greatest width dimension of stop part ") on the position of the left and right projection 53,53 of stop part 5 is longer than the width dimensions 51w (hereinafter referred to as " width dimensions of stopper body ") in the direction, left and right of the stopper body 51 below left and right projection 53,53, also than and position (part that left and right projection 53,53 contacts) corresponding to left and right projection 53,53 on the interval 92w (hereinafter referred to as " interval of left right vertical frame ") of left right vertical frame 92,92 long. And, the width dimensions 51w of stopper body 51 becomes the size identical with the interval 92w of left right vertical frame 92,92. If the words being described with symbol, then in the present embodiment, the size relationship of stop part 5 and framework 91 becomes the relation of 51w=92w < 53w, but the present invention is not limited to this, it is also possible to be the relation of 51w≤92w < 53w. If this relation, by making the left right vertical frame 93,93 of framework 91 be positioned at the lower section of left and right projection 53,53, and stop part 5 and framework 91 is made to become connecting state.

The left and right side of left and right projection 53,53 stopper body 51 of (rotary area of left right vertical frame 92,92 is outer) from the rotary area being in framework 91 projects to and arrives to (rotary area of left right vertical frame 92,92 is interior) in the rotary area of framework 91. Therefore, when being in left and right projection 53,53 and recover the state of shape before for distortion, namely restore state, the framework 91 of rotation cannot be passed through, and thus the framework 91 under prevention connecting state rotates; When be in state that left and right projection 53,53 extrudes and be out of shape by framework 91, namely elastic deformation, it is possible to realize passing through of framework 91, thus allow framework 91 to rotate. Like this, left and right projection 53,53 limits the rotation of framework 91.

In addition, as shown in Figure 6, the upper surface of projection 53 becomes the scarp 53u raised along with trend front. More specifically, the upper surface of projection 53, in the scope except its rear ends, becomes the scarp 53u into regulation angle of inclination becoming high along with trend front gradually. And, the corner between the leading section of the upper surface of each projection 53 and the front surface of each projection 53 implements chamfering.Equally, corner between the rearward end of the upper surface of each projection 53 and the rear surface of each projection 53 also implements chamfering. These corners become the curved surface of the circular arc shape that drum goes out laterally.

Further, the upper and lower of projection 53 to thickness 53t along with trend front and become thick. More specifically, the upper surface of projection 53 is aforesaid scarp 53u, but becomes horizontal plane below projection 53, thus, the upper and lower of projection 53 to thickness 53t become thick along with from trend front, rear.

The slide fastener 1 of aforesaid first enforcement mode will draw the framework 91 climbing 9 to be attached on stop part 5 as described in following (1)～(3).

(1) first, drawing and climb 9 and make to draw the front surface of head main body 7 to collide relative to stop part 5, the front surface of head main body 7 contacts with drawing to make the rear surface of stop part 5. Now, draw the front portion of the upper flange 72 of head main body 7 and the upper surface of stop part 5, therefore, draw the part of downside compared with upper flange 72 in the front surface of head main body 7 to contact with the rear surface of stop part 5.

(2) then, make to draw climb 9 by one to supporting axle 8,8 centered by front rotate, as shown in (a) of Fig. 6, (a) of Fig. 7, left right vertical frame 92,92 is placed on left and right projection 53,53 respectively. Now, framework 91 further rotates to front and is stoped by left and right raised 53,53. In addition, it can judge that namely the situation that framework 91 does not link with stop part 5 links releasing state by the reason of following (2.1)～(2.3).

(2.1) left and right projection 53,53 is positioned at the lower section of left right vertical frame 92,92, therefore, if under overlooking, then the left right vertical frame 92,92 of framework 91 can visuognosis completely, but a part for left and right projection 53,53 is by indulging, and frame 92,92 is covered, and thus the global shape of left and right projection 53,53 cannot visuognosis.

(2.2) left right vertical frame 92,92 is different from the color of stop part 5, therefore, it is easy to distinguish vertical frame 92 and stop part 5, when cannot visuognosis projection 53, it is possible to be judged as that projection 53 is hidden in the lower section of left right vertical frame 92,92.

(2.3) upper surface of left and right projection 53,53 becomes the scarp 53u raised along with trend front, left right vertical frame 92,92 to load in the way of the 53u of this scarp, therefore, left right vertical frame 92,92 tilts, the horizontal frame 93 of framework 91 be positioned at compared with fulcrum side top, can feel time under overlooking horizontal frame 93 from close to.

(3) last, if the horizontal frame 93 of framework 91 is pushed away downwards together with grip part 94 into, then left and right projection 53,53 is out of shape by elasticity and twisted downwards. Now, owing to the side of projection 53 becomes scarp 53s, so making left and right projection 53,53 elasticity distortion in the way of inner side (stopper body 51 side) in the lateral direction gradually is pushed into by left right vertical frame 92,92. Therefore, the side of projection 53 is the situation of scarp 53s, such as, compared with the situation that the side of projection 53 is vertical surface, more easily makes projection 53 be out of shape. In addition, owing to also can be delivered to stopper body 51 pushing away the part into this push-on force during projection 53, so being out of shape in the way of making the hole 51h of stopper body 51 side twisted, thus projection 53 becomes easy distortion. Like this, when distortion limit, left and right projection 53,53 limit makes left right vertical frame 92,92 wipe when left and right projection 53,53 side is passed through, then as shown in (b) of Fig. 6, (b) of Fig. 7, left and right projection 53,53 reverts to original shape by elasticity, and the lower section of left right vertical frame 92,92 to raised 53 is moved.Now, become the state that the left and right side of stopper body 51 and front surface are surrounded by the framework 91 of U-shaped, namely draw and climb 9 states linked with stop part 5. Under this connecting state, left right vertical frame 92,92 contacts with the left and right side of stopper body 51, and the grip part 94 for ribbon covering horizontal frame 93 contacts with the front surface of stopper body, and left and right projection 53,53 stops the rotation of framework 91. And, can judge, by the reason of following (3.1)～(3.2), the situation that framework 91 links with stop part 5.

(3.1) as shown in Figure 3, it is possible to visuognosis goes out and is configured with left and right projection 53,53 above left right vertical frame 92,92, and the situation that a part for vertical frame 92 is covered by projection 53.

(3.2) owing to left right vertical frame 92,92 is different from the color of stop part 5, so easily distinguishing vertical frame 92 and stop part 5, when visuognosis is to projection 53, left right vertical frame 92,92 because of projection 53 existence and visuognosis is just like be separated up and down.

In addition, when being set to connecting state link releasing state, by being pulled upward and make framework 91 rotate a little grip part 94, after making left right vertical frame 92,92 contact with the lower surface of left and right projection 53,53 respectively, grip part 94 is pulled further upward. Like this, left and right projection 53,53 is out of shape by elasticity and twisted upward, and by by left right vertical frame 92,92 gradually inner side (stopper body 51 side) in the lateral direction push away in the way of elasticity distortion, thus, left right vertical frame 92,92 is wiped the side of left and right projection 53,53 and is passed through, and horizontal frame 93 is positioned at the top of stopper body 51.

As shown in Figure 8, Figure 9, the slide fastener 1 that mode implemented in following by the slide fastener 1 of the 2nd enforcement mode of the present invention with first is different, that is: the selection face in the left and right side of stopper body 51 and these three faces of front surface is set to front surface, and uses the stop part 5 over the front surface with projection 53; Projection 53 stops the horizontal frame 93 of framework 91 to rotate; And use and framework 91 and grip part 94 are set to drawing of one climb 9.

More specifically, when top view stopper body 51, the middle portion that projection 53 is formed on the length direction of total length L2 in front relative to the forming position of stopper body 51, this front is as the limit formed by selection face i.e. front surface.

In addition, the distance 88L to the front surface of stopper body 51 from the axle main body Bu81Zhou center of the supporting axle 8 drawn on head main body 7, when the rear surface drawing the front surface of head main body 7 with stopper body 51 contacts, is set to identical or slightly short with size (hereinafter referred to as " rotation radius of horizontal the frame ") 9r of the rotation center (axle main body Bu81Zhou center) from framework 91 to the rear surface of horizontal frame 93 by the slide fastener 1 of the 2nd enforcement mode. And, the distance 89L of axle main body Bu81Zhou center to the front surface of projection 53 from supporting axle 8 is set to longer than the rotation radius 9r of horizontal frame 93. Therefore, by making the horizontal frame 93 of framework 91 be positioned at the lower section of projection 53, stop part 5 and framework 9 become connecting state.

In addition, draw and climb 9 and be set to make the horizontal frame 93 of framework 91 to the wide cut shape extended in the outside in the radius direction centered by supporting axle 8,8 by, and the Outboard Sections in the radius direction of this horizontal frame 93 is set to grip part 94. In this case, therefore, draw that to climb 9 be the rigid body that framework 91 is integrated with grip part 94.

In the slide fastener 1 of the 2nd enforcement mode, if framework 91 and stop part 5 link, then projection 53 is configured on the centre portion, direction, left and right of the horizontal frame 93 of framework 91, it is possible to visuognosis is to the existence of projection 53.In addition, owing to a part for horizontal frame 93 is covered by projection 53, it is possible to visuognosis climbs 9 links with stop part 5 to drawing.

As shown in Figure 10, the slide fastener 1 that mode implemented in following by the slide fastener 1 of the 3rd enforcement mode of the present invention with first is different, that is: about front and back to, left and right projection 53,53 is formed in the rear portion of the left and right side of stopper body 51; Projection 53 is not only by lower surface but also upper surface is also set to horizontal plane; About upper and lower to, the upper and lower that the position of left and right projection 53,53 is set to stopper body 51 is to centre portion.

As shown in figure 11, the slide fastener 1 of the 4th enforcement mode of the present invention is different with the slide fastener 1 of the first enforcement mode in following, that is, have multiple projection 53 on the face, right side of stopper body 51, and have the connecting state of multiple stop part 5 and framework 91.

More specifically, in this enforcement mode, on the face, right side of stopper body 51, it is formed with two projections 53 at spaced intervals along to support the sense of rotation of the vertical frame 92 rotated centered by axle 8. In addition, more than the size up and down of vertical frame 92 of horizontality it is set to relative to the interval of this sense of rotation. And, in the example in the figures, two projections 53,53 are configured on the face, right side of stopper body 51 with the state isolated along the longitudinal direction and isolate along the vertical direction. The upper surface of the 2nd projection 53 being positioned at downside is parallel with the lower surface of the first projection 53 being positioned at upside, is the scarp with the inclination raised gradually along with trend front.

4th enforcement mode slide fastener 1 when by stop part 5 with have two connecting states when drawing and climb 9 link. First connecting state is the state making vertical frame 92 be clipped between the projection 53 of upside and the 2nd projection 53, and becomes the heeling condition that vertical frame 92 raises along with horizontal frame 93 side of trend. Like this, horizontal frame 93 with stretch out sheet 52 between the upper and lower every becoming wide compared with the situation under the 2nd connecting state next illustrated, it becomes more easily finger is inserted into horizontal frame 93 and stretches out between sheet 52, and more easily the first projection 53, dismantle framework 91.

2nd connecting state is that vertical frame 92 is positioned at the state below the 2nd projection 53, in order to release the link of stop part 5 with framework 91, it is necessary to according to the order dismounting framework 91 of the 2nd projection 53, first projection 53. Therefore, the 2nd connecting state is it may be said that be that connecting state is more firm.

The present invention is not limited to above-mentioned enforcement mode, can suitably change in the scope not departing from its purport. Such as, although not limiting the object of the slide fastener 1 installing the present invention, but the flexible container of such as fluid conveying can be enumerated. If the flexible container being filled with fluid being applied the words of external force, then slide fastener 1 is for separately, to drawing 6 applying from the power the direction that stop part 5 leaves, but as long as the connecting state of the such framework 91 of the present invention with stop part 5 can be guaranteed, just can prevent slide fastener 1 separately.

In addition, in the embodiments of the present invention, the left and right side or front surface of stopper body 51 has projection 53, though it is not so limited, can also have projection 53 on the left and right side of stopper body 51 and front surface respectively. In addition, in the embodiments of the present invention, projection 53 divides into the middle portion of the total length for the limit formed by selection face relative to the forming position of stopper body 51 in the situation of overlooking, though it is not so limited, can also be the end of the total length on limit.

Further, band 3,3 one is flexed into L-shaped and formed by used in the slide fastener 1 of the first enforcement mode, though it is not so limited, can also be one be level to band 3,3.In this case, the relative horizontal side edge being with 3,3 is fixed by chain denture 4 along one.

In addition, in the embodiments of the present invention, supporting axle 8,8 is set to independent part by framework 91 and respectively, and the couple's supporting axle 8,8 as individual part is given prominence to the left and right side of head main body 7 from drawing. But it is not limited to this, it is also possible to supporting axle 8,8 is set to one by framework 91 and, and this couple is supported axle 8,8 and interts in the axle support holes (not shown) being formed on the left and right side drawing head main body 7.

Further, what use in the slide fastener 1 of the first enforcement mode draws 6 to be formed with hole 51h on the left and right side of stopper body 51, and this hole 51h is easy to stopper body 51 is out of shape, but is not limited to this, in order to make stopper body 51 easily be out of shape, it is also possible to form hole 51h on the front surface. In addition, hole 51h is formed as circular in the example of fig. 6, though it is not so limited, can also be along the longitudinal direction or upper and lower to etc. the long hole of prescribed direction length or other shapes.
