The effect of invention

Slide fastener chain of the present invention, at the relative band side edge part of first and second zipper strip of pair of right and left, have along a plurality of magnetic chain teeth of the magnetic force of strip length direction across band table the inside be listed as and establish.In addition, these magnetic chain toilet article have: shank; The neck shrinking in the front and back of strip length direction; The engagement head expanding to the front and back of strip length direction, and engagement head have can be from band table direction by the size shape of magnetic force intercalation and disengagement between the neck of the magnetic chain tooth adjoining each other of engagement subject side.

In addition, in this slide fastener chain, described each magnetic chain toilet article have rotation to allow portion, when the described magnetic chain tooth of left and right is separated from the state of engagement, this rotation allows that portion can avoid the magnetic chain tooth of a side and the described magnetic chain tooth of opposite side to interfere, and the magnetic chain tooth of allowing a side rotates centered by the axle along bandwidth direction, this rotation allows that portion is configured on the front and back sides with first surface side and at least one side with the front and back sides of second side of described each magnetic chain tooth.

Present inventors etc. are in order to utilize magnetic force that the magnetic chain tooth of left and right is meshed more swimmingly, as in the past, do not make the magnetic chain tooth of left and right mesh successively from bandwidth direction, but produce direction from band table, mesh better idea, and by repeatedly studying with keen determination and tested the present invention.

; as the present invention; in the situation that be configured to, make magnetic chain tooth direction engagement from band table of left and right, separated slide fastener chain; when making the engagement of magnetic chain tooth or separation; can limit make zipper strip not from band be difficult to crooked bandwidth direction but from band holds flexible band table direction carry out flexing, engagement or the separation of magnetic chain tooth carried out on limit.Therefore,, even if do not use pull head, also can, by utilizing the magnetic force of each magnetic chain tooth to make the magnetic chain tooth of left and right mutually engage swimmingly and mesh, in addition, can also make the magnetic chain tooth of engagement easily separated.

In addition, for example make the chain tooth of left and right from the slide fastener in the past of bandwidth direction engaging, must make the alternately engaging of left and right one by one of chain tooth, but as the present invention, by magnetic chain tooth direction from band table of left and right is engaged, can make to be configured in adjacent plural magnetic chain tooth on the zipper strip of a side (and, make to be configured in the whole magnetic chain tooth on the zipper strip of a side) be fastened on the magnetic chain tooth as engagement subject side simultaneously, can be simply and promptly carry out the engaging of the magnetic chain tooth of left and right.

In addition, in the slide fastener 90 of the described patent documentation 2 shown in Figure 28 and Figure 29, in this patent documentation 2 without any about making magnetic chain tooth 92, the 92 ' direction engaging from band table of left and right, separated record, in addition, although be the magnetic chain tooth 92,92 that makes left and right ' from the engaging of bandwidth direction, separated structure according to having used pull head 94 known, but only observe the magnetic chain tooth as shown in figure 28 92,92 of this slide fastener 90 ' shape, think these magnetic chain teeth 92,92 ' have can direction engaging from band table, separated geomery.

But, be assumed to there is the magnetic chain tooth 92,92 of left and right as shown in figure 28 of example ', and do not have in the situation of slide fastener chain of pull head 94, although can utilize magnetic force to make the direction of magnetic chain tooth 92,92 ' from the band table engaging of left and right, exist and be difficult to make the magnetic chain tooth 92,92 of the left and right in engagement ' to the problem of direction separation in band table.

Specifically describe, for example, there are two kinds of magnetic chain tooth 92,92 ' methods of separation in direction in band table that make the left and right in engagement, the first method is: make the zipper strip of a side along direction warpage in band table, the magnetic chain tooth 92 that simultaneously makes to be arranged on this zipper strip is separated in direction in band table from the chain denture of engagement subject side one by one; The second method is: the zipper strip of a side is mentioned abreast, and the whole magnetic chain teeth 92 that make to be arranged on this zipper strip are simultaneously separated in direction in band table.

For example as the former the first method, the zipper strip that makes side warpage in direction in band table, and make to be arranged on magnetic chain tooth 92 on this zipper strip one by one in the situation of direction separation in band table, need magnetic chain tooth 92 that limit makes a side to rotate with respect to the mode with face tilt of the zipper strip of opposite side with the height center line of the above-below direction of this magnetic chain tooth 92, limit makes it from a magnetic chain tooth 92 ' pull-off in direction in band table of engagement subject side.

But, in the situation that be the magnetic chain tooth 92,92 shown in Figure 28 ', when magnetic chain tooth 92, the 92 ' engagement of left and right, the magnetic chain tooth 92 of the opposite side of the magnetic chain tooth 92 of a side and engagement subject side ' the 96a of post portion, state that 96a ' contacts in mutual face each other or approaching state.

Therefore, even if make as described above magnetic chain tooth 92 rotation of a side, also can with the magnetic chain tooth 92 ' interference of opposite side, thereby can not freely rotate, can cause hooking, can not make the magnetic chain tooth 92 of a side from the chain denture pull-off in direction in band table one by one of engagement subject side.Therefore, can not make the zipper strip of a side along direction warpage band table from the state limit of magnetic chain tooth 92, the 92 ' engagement of left and right, it is separated to direction in band table one by one that limit makes to be arranged on magnetic chain tooth 92 on this zipper strip.

On the other hand, in the situation that as the second method of the latter, by the zipper strip of a side mention abreast, and make to be arranged on simultaneously whole magnetic chain tooth 92 on this zipper strip from the chain denture of engagement subject side to band table direction separation, need to make mutually a plurality of magnetic chain teeth 92,92 by magnetic-adsorption ' simultaneously move to the opposition side of direction in band table.

But, make so a plurality of magnetic chain teeth 92, the 92 ' in the situation that of moving simultaneously and make it separated, existence during due to separation, needs great power and requires zipper strip to form rigid body etc., so can not easily make the problem of magnetic chain tooth 92, the 92 ' separation of left and right.

That is, in the situation that for shown in Figure 28 have magnetic chain tooth 92,92 ' the slide fastener 90 of patent documentation 2, if do not use pull head 94, extremely difficult by magnetic chain tooth 92, the 92 ' separation of left and right.

To this, in slide fastener chain of the present invention, as described, at the front and back sides with first surface side of each magnetic chain tooth with on at least one side in the front and back sides of second side, dispose rotation and allow portion, thus, in the described magnetic chain tooth engagement of left and right, when separated, can avoid the described magnetic chain tooth interference of magnetic chain tooth with the opposite side of a side, can centered by the axle along bandwidth direction, be rotated.

Therefore, in slide fastener chain of the present invention, by making the zipper strip of a side along direction warpage in band table, the height center line that can limit makes to be arranged on the above-below direction of the magnetic chain tooth on this zipper strip rotates obliquely with respect to the zone face of the zipper strip of opposite side, limit makes it not and the easily pull-off in direction in band table between the magnetic chain tooth of engagement subject side interferingly of the magnetic chain tooth of engagement subject side, thus, can make the magnetic chain tooth of left and right separated swimmingly.

Especially, in the present invention, described rotation allows that portion is by being configured in described engagement head and the front and back sides with first surface side in described neck of described each magnetic chain tooth and forming with the conical surface or flexure plane at least one side in the front and back sides of second side, and the size that this conical surface or flexure plane form the strip length direction that makes described magnetic chain tooth reduces gradually along the direction inside the band table away from described first and second zipper strip.

Because such conical surface or flexure plane are configured on the engagement head and neck of each magnetic chain tooth, so, when the described magnetic chain tooth separation of the left and right that makes to mesh, can avoid reliably the magnetic chain tooth of a side and the magnetic chain tooth of opposite side to interfere, and can make the magnetic chain tooth of left and right separated swimmingly.And, make the magnetic chain tooth of left and right when direction attracts and meshes from band table by magnetic force, the engagement head of the magnetic chain tooth of one side easily can be imported to via the conical surface or flexure plane between the neck of magnetic chain tooth of opposite side, can more smooth and easy and stably make the magnetic chain tooth engagement of left and right.

Especially, in this case, the conical surface of each magnetic chain tooth or flexure plane are configured on the front and back sides with first surface side and the front and back sides with second side in engagement head and neck, thus, when the magnetic chain tooth engagement that makes left and right by magnetic force, the engagement head of the magnetic chain tooth of one side more stably can be guided via the conical surface or flexure plane between the neck of the magnetic chain tooth of opposite side, can carry out more swimmingly the engagement of magnetic chain tooth.

In addition, when the magnetic chain tooth of left and right that makes engagement is separated, the magnetic chain tooth that can limit makes a side easily rotates with respect to the magnetic chain tooth of opposite side, and limit makes the magnetic chain tooth of left and right more separated.And if configure the conical surface or flexure plane on the front and back sides with first surface side in engagement head and neck and the front and back sides with second side, the outward appearance of each magnetic chain tooth (exterior quality) is improved, the appearance design that can improve slide fastener.

In such slide fastener chain of the present invention, the described conical surface has first conical surface and second conical surface larger than this first conical surface inclined degree.Especially, in this case, described first conical surface is configured in on side of first surface side and another side with second side, and described second conical surface is configured in on another side of first surface side and a side with second side.Thus, in magnetic chain tooth when engagement that makes left and right, the engagement head of the magnetic chain tooth of a side more easily can be directed between the neck of magnetic chain tooth of opposite side.

In addition, in slide fastener chain of the present invention, magnetic chain toilet article have: be arranged on the first magnetic chain tooth on the first zipper strip; Be arranged on the second magnetic chain tooth on the second zipper strip, the first magnetic chain toilet article have: at first extension stretching out with the place ahead of first surface side direction neck or the taper portion at rear of the first zipper strip; At zipper strip, with second side, be formed on the engagement rear end side of head or the first step portion of front.In addition, the second magnetic chain toilet article have: at second extension stretching out with the place ahead of second side direction neck or the taper portion at rear of the second zipper strip; At the second zipper strip, with first surface side, be formed on the engagement rear end side of head or the second step portion of front.

Thus, can make the first magnetic chain tooth be engaged on swimmingly the second magnetic chain tooth from the band first surface side of the zipper strip of opposite side.In addition, during the state that is engagement at the first magnetic chain tooth and the second magnetic chain tooth, first step portion and first extension that can support respectively the first magnetic chain tooth by the second extension and the second step portion of the second magnetic chain tooth, therefore, for example, even if the first magnetic chain tooth is subject to pushing force (jack-up power) from band first surface side, also can prevent the engagement releasing of the magnetic chain tooth of left and right.

And in the situation that being this slide fastener chain, the engagement head of the engagement head of the first magnetic chain tooth and the second magnetic chain tooth is being with first surface side and is being with second top-cross for engagement along strip length direction.Therefore, can make the chain denture of the first magnetic chain tooth and the chain denture of the second magnetic chain tooth mesh well about direction balance in band table.

In this situation, the height and position at the bottom surface of second step portion place is set on the centre-height position of the second magnetic chain tooth, or comparing, mesh height dimension in head with this centre-height position becomes on large position.In addition, the height and position at the face that the stretches out place of the second extension is set on described centre-height position, or compare with this centre-height position, on position that the height dimension in the second extension uprises.And the face that stretches out of the first extension and the bottom surface of first step portion are configured to, when the engagement of first and second magnetic chain tooth, with respect to the bottom surface of second step portion and the face that stretches out of the second extension butt or face respectively.

Thus, can easily form the first extension of the first magnetic chain tooth and second step portion and second extension of first step portion and the second magnetic chain tooth, in addition, can not make the first magnetic chain tooth and the second magnetic chain tooth mutually interfere, can make more swimmingly its engagement, separation.And, under the state of first and second magnetic chain tooth engagement, can easily guarantee that slide fastener chain is to the flexibility of direction in band table.

And, in this situation, because the bottom surface of second step portion and the face that stretches out of the second extension are configured in identical height and position, therefore, can stably support first step portion and the first extension by the second extension and second step portion.Especially, the height and position stretching out in face of the bottom surface of second step portion and the second extension is configured on described centre-height position, and, as long as the mode with the bottom surface of the face that stretches out of the first extension and the bottom surface of first step portion and second step portion and the face that the stretches out butt of the second extension configures, just can more stably support first step portion and the first extension.In addition, in this situation, because first and second magnetic chain toilet article have symmetrical shape, so, can make the exterior quality of slide fastener chain improve.

In slide fastener chain of the present invention, the front inclined plane that the first magnetic chain tooth reduces from the neck lateral head front end of this engagement head gradually at the height with second side with direction in the band table that makes to mesh in head.In addition, the front inclined plane that the second magnetic chain tooth reduces from the neck lateral head front end of this engagement head gradually at the height with first surface side with direction in the band table that makes to mesh in head.Thus, at first and second magnetic chain tooth during from the mutual butt of bandwidth direction, make the first magnetic chain tooth with respect to the second magnetic chain tooth along inclined plane relatively to the band first surface side shifting of the second zipper strip, can make the direction engagement from band table of first and second magnetic chain tooth.

Thus, the magnetic force that the magnetic force having by the first magnetic chain tooth 11 and the second magnetic chain tooth 21 have, first and second magnetic chain tooth 11,21 adsorbs mutually, and the first engagement head 14 of the first magnetic chain tooth 11 is directed between the second neck 23 of the second magnetic chain tooth 21 adjoining each other and from band table the top of direction chimeric (with reference to Fig. 7).In addition, meanwhile, the second engagement head 24 of the second magnetic chain tooth 21 is directed to direction chimeric (with reference to Fig. 8) between the first neck 13 of the first magnetic chain tooth 11 adjoining each other and from band table.

Now, in the belt surface side (band first surface side) of the front and back sides of first and second magnetic chain tooth 11,21 be with in rear side (being with second side) and be formed with the first conical surface 17a, 27a, and, on the side that is formed with first and second stage portion 16,26 of first and second magnetic chain tooth 11,21, be formed with angle of inclination second conical surface 17b, the 27b larger than the first conical surface 17a, 27a.

More specifically describe, the first conical surface 17a of the first magnetic chain tooth 11 is formed on the leading flank (side of former code side) of the upper side of the first zipper strip 1a and the leading flank and trailing flank of trailing flank (side of rear code side) and lower side.Angle of inclination second conical surface 17b larger than this first conical surface 17a is formed on the leading flank of upper side and the trailing flank of lower side of the first zipper strip 1a.Especially, these second conical surfaces 17b is formed on than more close the first engagement head 14 sides of the first shank 12 in bandwidth direction (left and right directions), in addition, in band table, direction (above-below direction) is upper, from the upper and lower surface side of the first magnetic chain tooth 11, be formed to above-below direction central authorities near.

The first conical surface 27a of the second magnetic chain tooth 21 is formed on the leading flank (side of former code side) of the upper side of the second zipper strip 1b and the leading flank and trailing flank of trailing flank (side of rear code side) and lower side.Angle of inclination second conical surface 27b larger than this first conical surface 27a is formed on the trailing flank of upper side and the leading flank of lower side of the second zipper strip 1b.Especially, these second conical surfaces 27b is upper in bandwidth direction (left and right directions), is formed on than more close engagement head 24 sides of the second shank 22, in addition, in band table, direction (above-below direction) is upper, from the upper and lower surface side of the second magnetic chain tooth 21, be formed to above-below direction central authorities near.

Therefore, at the first magnetic chain tooth 11 because of upper side (belt surface side) when engagement of magnetic force from the second magnetic chain tooth 21, via the first conical surface 17a, 27a and the second conical surface 17b, 27b, the first engagement head 14 of the first magnetic chain tooth 11 can be guided between the second neck 23 of two adjacent the second magnetic chain teeth 21 and it is easily imported.And, the second engagement head 24 of the second magnetic chain tooth 21 can also be guided between the first neck 13 of two adjacent the first magnetic chain teeth 11 and it is easily imported.And, now, from for example with respect to direction band table forwards or the angle that tilts of rear, also can respectively meshing head 14,24 and import swimmingly between the neck 23,13 that meshes subject side first and second magnetic chain tooth 11,21.

In addition, in the present embodiment 1, it is upper that the second conical surface 17b of the lower side of the first zipper strip 1a of the first magnetic chain tooth 11 is formed on the trailing flank side of side (rear code) of this first magnetic chain tooth 11, and the second conical surface 27b of the upper side of the second zipper strip 1b of the second magnetic chain tooth 21 is formed on the trailing flank (side of rear code side) of this second magnetic chain tooth 21.

Like this, when first and second magnetic chain tooth 11,21 engagement that makes left and right, because angle of inclination large the second conical surface 17b, 27b are respectively formed at the importing side of each magnetic chain tooth 11,21, therefore, each can be meshed to head 14,24 is directed between the neck 23,13 that meshes subject side swimmingly.

Thus, can make respectively meshing between the neck 23,13 of magnetic chain tooth 21,11 that head 14,24 is entrenched in engagement subject side of first and second magnetic chain tooth 11,21, and, can make first and second magnetic chain tooth 11,21 as Fig. 1 and as shown in Figure 9, on the equal height position of above-below direction smooth and easy and stably engagement.

In addition, in the slide fastener 10 of the present embodiment 1, even if (the relative position of the first chain denture 11a and the second chain denture 21a staggers in strip length direction, even if stagger in the position of former code 31 and the position of the second magnetic chain tooth 21 that is configured in the front end of the second chain denture 21a in strip length direction), by the magnetic force of first and second magnetic chain tooth 11,21, also the engagement head of each magnetic chain tooth 11,21 14,24 can be guided between the neck 23,13 of the magnetic chain tooth 21,11 of engagement subject side, thereby easily make first and second magnetic chain tooth 11,21 engagements.

In addition, when first and second magnetic chain tooth 11,21 has meshed, magnetic force due to first and second magnetic chain tooth 11,21, the face that the stretches out 15a of the first extension 15 of the first magnetic chain tooth 11 and the bottom surface 16a of first step portion 16, as shown in Figures 10 and 11 like that, be connected on the bottom surface 26a of second step portion 26 and the face that the stretches out 25a of the second extension 25 of the second magnetic chain tooth 21.Thus, can make the engagement of first and second magnetic chain tooth 11,21 stable.

In this situation, the slide fastener 10 of the present embodiment 1, due to respectively meshing between the neck 23,13 of magnetic chain tooth 21,11 that head 14,24 is entrenched in engagement subject side, so have good horizontal tensile strength of first and second magnetic chain tooth 11,21.Therefore,, even if the zipper strip 1 in left and right is subject to lateral pull and is pulled to the outside of bandwidth direction, also can stably maintain the engagement of first and second magnetic chain tooth 11,21.

In addition, in this slide fastener 10, by the first conical surface 17a, 27a and the second conical surface 17b, 27b are set on first and second magnetic chain tooth 11,21, even under the state of first and second magnetic chain tooth 11,21 engagements, also can be easily by slide fastener 10 bending in direction in band table, flexibility is good.

And, in this slide fastener 10, in the front-end configuration of the first chain denture 11a, there is former code 31, code 32 after the backend arrangement of the second chain denture 21a has.Therefore, under the state of first and second chain denture 11a, 21a engagement, when being subject to lateral pull, can effectively prevent from dispose former code 31 the first chain denture 11a front and dispose the rear end side of code the second chain denture 21a of 32 there is so-called engagement cracking, can more stably maintain the engagement of first and second magnetic chain tooth 11,21.

That is to say, in the situation that not configuring former code 31 and rear code 32, if be subject to lateral pull near the end side of first and second zipper strip 1a, 1b, be configured in the first magnetic chain tooth 11 of end of first and second chain denture 11a, 21a and/or the second magnetic chain tooth 21 can be on the zone face of first and second zipper strip 1a, 1b with to the mode of the direction rotation of magnetic chain tooth 11,21 engagement releasing is each other moved.Thus, from be configured in first and second magnetic chain tooth 11,21 of the end of first and second chain denture 11a, 21a start engagement be disengaged in turn, with first and second zipper strip 1a of left and right, 1b master, depending on being the mode of Y word shape, first and second chain denture 11a, 21a are gradually separated from the end side of a side.

But, by configuring as described above former code 31 and rear code 32, the first magnetic chain tooth 11 and/or the second magnetic chain tooth 21 that can prevent from being configured in the end of chain denture 11a, 21a rotate as described above, can effectively prevent that first and second chain denture 11a, 21a are separated from the end side of a side.

Below, about the slide fastener 10 of the present embodiment 1, illustrate and make first and second magnetic chain tooth 11,21 from the method for the state separation of engagement.

In the slide fastener 10 of the present embodiment 1, if the situation that for example the first zipper strip 1a consists of rigid body, by the first zipper strip 1a is mentioned upward abreast with respect to the second zipper strip 1b, whole the first magnetic chain teeth 11 that are arranged on the first zipper strip 1a are mentioned to the top of the second magnetic chain tooth 21 simultaneously.Therefore, can make this first magnetic chain tooth 11 from the second magnetic chain tooth 21 pull-offs, can the first magnetic chain tooth 11 in engagement is separated with the second magnetic chain tooth 21.

In addition, in addition, in the slide fastener 10 of the present embodiment 1, as shown in figure 12, by from band rear end side or band front by the first zipper strip 1a to belt surface side (upper side) bending, along with the action of this first zipper strip 1a, the first magnetic chain tooth 11 being arranged on this first zipper strip 1a is mentioned to the top of the second magnetic chain tooth 21 one by one, can make this first magnetic chain tooth 11 from the second magnetic chain tooth 21 pull-offs.

In this situation, each first magnetic chain tooth 11, the height center line limit of the above-below direction of this first magnetic chain tooth 11 is to rotate with respect to the mode with face tilt of the second zipper strip 1b, and limit is mentioned upward from 21 of the second magnetic chain teeth.Now, in the slide fastener 10 of the present embodiment 1, on the front and back sides of the band table the inside of first and second magnetic chain tooth 11,21 side, as avoiding the rotation of the interference of the first magnetic chain tooth 11 and the second magnetic chain tooth 21 to allow portion, be formed with the first conical surface 17a, 27a and the second conical surface 17b, 27b.Therefore, can make that the first magnetic chain tooth 11 does not interfere ground with the second magnetic chain tooth 21 of engagement subject side, limit rotates swimmingly limit from the second easily pull-off of magnetic chain tooth 21 centered by the axle along bandwidth direction.
