Japanese Patent No. 5460862 - [PTL 2]
Japanese Patent No. 5042358 - Recently, there is an increasing demand for lesser force for moving a slider so as to close a slide fastener even though there has been hardly ever for such demand before. The present inventors has conducted keen analysis on this matter and revealed that a type of slide fastener disclosed in the
patent literature 1 has a following problem. In particular, as illustrated inFig. 8 , left and right fastener elements E1' and E2' come into initial contact inside of the slider when the slider moves forward. A rear protrusion of the posterior fastener element E2' of those left and right fastener elements E1' and E2' come into contact with a front protrusion of a fastener element E3', and thus greater force would be required to allow a rear protrusion of the fastener element E 1' to move across a front protrusion of the fastener element E2', i.e. increased resistance for sliding the slider. Note that the fastener elements E 1' and E2' (E2' and E3') paired for initial contact would be kept in contact between a first position away from a rear end of thecoupling pillar 93 of theslider 9 by a first distance D1' to a second position away from the rear end of thecoupling pillar 93 by a second distance D2'. - One might consider to lower the height of the front and rear protrusions in order to avoid the increased resistance for sliding a slider, but this would result in a lowered strength of slide fastener against a lateral pulling force. Therefore, a technical problem the present invention concerns is to reduce the resistance for sliding a slider while maintaining sufficient height of the front and rear protrusions of the fastener elements.
- Slide fastener according to an aspect of the present disclosure includes: left and right fastener stringers with fastener elements attached to opposed side-edges of fastener tapes, each fastener element including an attachment base secured to the side-edge of the fastener tape and a head having an engagement protrusion positioned away from said side-edge of the fastener tape, and the engagement protrusion including a front protrusion protruding forward and a rear protrusion protruding rearward; and a slider that moves forward to engage left and right fastener elements included in the left and right fastener stringers, the left and right fastener elements coming into initial contact on the front protrusion and the rear protrusion alternately inside of the slider as the slider moves forward. When a given pair of left and right fastener elements included in the left and right fastener elements come into initial contact on the rear protrusion of an anterior fastener element of the given pair of left and right fastener elements and the front protrusion of a posterior fastener element of the given pair of left and right fastener elements, the rear protrusion of the posterior fastener element is not in contact with the front protrusion of a fastener element immediately posterior to said posterior fastener element.
- In some embodiments, the engagement protrusion includes: nearer sloped surfaces that diverge from each other as being away from the attachment base; farther sloped surfaces that approach each other as being away from the attachment base; and top portions each of which being formed between the nearer sloped surface and the farther sloped surface. The farther sloped surface is sectioned into plural sloped regions having different angles of inclination, and the sloped region situated closer to the top portion may be inclined more gently than the sloped region situated farther from the top portion.
- In some embodiments, the left and right fastener elements come into initial contact on the respective sloped regions situated closer to the top portion. The top portion may include a flat surface that extends evenly along a direction the head protrudes from the side-edge of the fastener tape. Initial contact position of the left and right fastener elements may be on a center line of the slider. The head may include a plate portion having a thickness defined by a front surface on which the front protrusion is arranged and a rear surface on which the rear protrusion is arranged, said thickness being less than a thickness of the attachment base. Front recess may be formed between the front protrusion and the attachment base, and a rear recess may be formed between the rear protrusion and the attachment base.
- A method of designing a slide fastener according to another aspect of the present disclosure is one for designing a slide fastener that includes: left and right fastener stringers with fastener elements attached to side-edges of fastener tapes, each fastener element including an attachment base secured to the side-edge of the fastener tape and a head having an engagement protrusion positioned away from said side-edge of the fastener tape, and the engagement protrusion including a front protrusion protruding forward and a rear protrusion protruding rearward; and a slider that moves forward to engage left and right fastener elements included in the left and right fastener stringers, the left and right fastener elements coming into initial contact on the front protrusion and the rear protrusion alternately as the slider moves forward. The present designing method allows, when a given pair of left and right fastener elements included in the left and right fastener elements come into initial contact on the rear protrusion of an anterior fastener element of the given pair of left and right fastener elements and the front protrusion of a posterior fastener element of the given pair of left and right fastener elements inside of the slider, the rear protrusion of the posterior fastener element to be not in contact with the front protrusion of a fastener element immediately posterior to said posterior fastener element.
- An aspect of the present disclosure facilitates reduction of resistance for sliding a slider while maintaining sufficient height of the front and rear protrusions of fastener elements.

Figs. 1 to 8 . A skilled person would be able to combine respective embodiments and/or respective features without requiring excess descriptions, and would appreciate synergistic effects of such combinations. Overlapping descriptions among the embodiments are basically omitted. Referenced drawings aim mainly for describing inventions and are simplified for the sake of convenience of illustration. The respective features should be appreciated as universal features not only effective to slide fasteners presently presented but also effective to other various slide fasteners not presented in the present specification. - In the present specification, front-rear direction would be understood based on movement of
slider 9. Direction of movement of theslider 9 forclosing fastener stringers 3 and 4 is equal to a forward direction. Direction of movement of theslider 9 for openingfastener stringers 3 and 4 is equal to a rearward direction. Left-right direction would be understood based onfastener stringers 3 and 4 to be closed and opened by theslider 9. Up-down direction is orthogonal to the front-rear direction and the left-right direction and, for example, is orthogonal to tape faces of a fastener tape which define a thickness of the fastener tape. - As shown in
Fig. 1 , aslide fastener 1 has left andright fastener stringers 3 and 4, and aslider 9 that moves forward to close the left andright fastener stringers 3 and 4 and moves rearward to open the left andright fastener stringers 3 and 4. The fastener stringer 3, 4 has afastener tape fastener elements fastener elements edges fastener tapes fastener tapes front stops fastener element right fastener stringers 3 and 4 are coupled by a commonrear stop 83 at the rear ends of the arrays of thefastener elements front stop rear stop 83 can be omitted. The slide fastener should not be limited to one disclosed inFig. 1 . The present invention can be adapted to a conceal slide fastener in which fastener elements are concealed by fastener tape not to be seen. - The

fastener element fastener elements fastener elements edge 13, 14 (e.g. the core thread there) of thefastener tape fastener elements fastener elements fastener elements fastener elements edge 13, 14 (e.g. the core thread there) of thefastener tape fastener elements - As shown in
Figs. 2-4 , thefastener element attachment base edge fastener tape head edge fastener tape attachment base legs edge fastener tape coupling portion 53 to which the base ends of thelegs legs coupling portion 53 in the left-right direction outwardly (i.e. a direction directed away from a center line CL of the slide fastener in the left-right direction) so that a space is defined between thelegs edge 13, 14 (e.g. the core thread there) of thefastener tape legs projections edge 13, 14 (e.g. the core thread) from moving out of the accommodating space between thelegs - The
head attachment base head front protrusion rear protrusion front protrusion 41 and therear protrusion 42 are protruded to the opposite side on the same axis. The same holds true to thefront protrusion 43 and therear protrusion 44. Thehead plate portion 56 having a thickness defined by afront surface 56a on which thefront protrusion rear surface 56b on which therear protrusion attachment base 31,32 (in the front-rear direction). Afront recess 57 is formed between the front protrusion 41 (similarly the front protrusion 43) and theattachment base 31, and arear recess 58 is formed between the rear protrusion 42 (similarly the rear protrusion 44) and theattachment base 31. Thefront protrusion rear protrusion attachment base end surface 56c of theplate portion 56. - As shown in
Fig. 4 , the engagement protrusion B1 (similarly the engagement protrusion B2) has nearer slopedsurfaces 61 on the front and rear sides which diverge from each other as being away from theattachment base attachment base top portions 63 on the front and rear sides formed between the nearer slopedsurface 61 and the farther slopedsurface 62. Thefront protrusion top portion 63 on the front side, the nearer slopedsurface 61 and the farther slopedsurface 62 on the front side which approach each other as being away from theplate portion 56 of thehead rear protrusion top portion 63 on the rear side, the nearer slopedsurface 61 and the farther slopedsurface 62 on the rear side which approach each other as being away from theplate portion 56 of thehead - The farther sloped
surface 62 is sectioned into pluralsloped regions region 62a situated closer to thetop portion 63 is inclined more gently than the slopedregion 62b situated farther from thetop portion 63. As would be understood by comparingFig. 4 (fastener element of the present embodiment) andFig. 5 (conventional fastener element), the slopedregion 62a situated closer to thetop portion 63 is gently angled owing to the division of the farther slopedsurface 62 into the differently angledsloped regions slider 9 as would be understood from the following descriptions. Note that the inclination angle of the slopedregion 62b is equal to the inclination angle of the nearer slopedsurface 61. Thetop portion 63 includes a flat surface that extends evenly along a direction thehead edge fastener tape slider 9. - The
fastener element walls rear protrusion 42 of anotherfastener element Figs. 3 and 4 ). Likewise, thefastener element walls front protrusion 41 of anotherfastener element Fig. 4 ). Thewall attachment base front recess 57 and therear recess 58 are gradually increased as being away from theattachment base - The
slider 9 is configured to engage and disengage the left andright fastener elements slider 9 may be metal or plastic or ceramic for example, but may be a composite of these materials. As seen fromFigs. 1 and6 , theslider 9 has atop wing 91, a bottom wing 92, and acoupling pillar 93. Left and right front-mouths coupling pillar 93 and a rear-mouth 95 is arranged at the opposite side of thefront mouths slider 9 matches the center line CL of theslide fastener 1. Thecoupling pillar 93 has a cross-sectional shape in which the width in the left-right direction is gradually reduced rearward. Therefore, thecoupling pillar 93 has left and right guide surfaces 93m and 93n that approach each other rearward. Theend surface 56c of theplate portion 56 of thehead fastener element guide surface - Flanges (not-illustrated) protruding downward may be arranged at the left and right side-edges of the
top wing 91 to restrict the displacement in the left-right direction of the left andright fastener elements flanges Fig. 6 ). The flange (not-illustrated) at the left side-edge of thetop wing 91 and theflange 96m at the left side-edge of the bottom wing 92 are opposed, defining an insertion space for theleft fastener tape 11. The flange (not-illustrated) at the right side-edge of thetop wing 91 and theflange 96n at the right side-edge of the bottom wing 92 are opposed, defining an insertion space for theright fastener tape 12. - As understandable from
Figs. 6 and7 , the left andright fastener elements front protrusion rear protrusion slider 9 as theslider 9 moves forward. The initial contact is caused when theslider 9 moves forward. As theslider 9 moves forward, the left andright fastener elements slider 9 via thefront mouths slider 9. The left andright fastener elements slider 9 via thefront mouths coupling pillar 93 between them. As theslider 9 further moves forward, these left andright fastener elements mouths right fastener elements coupling pillar 93 by a predetermined distance, these left andright fastener elements rear protrusion 42 of thefastener element 21 and thefront protrusion 43 of the fastener element 22 (SeeFig. 6 ). Likewise, the initial contact can be caused between thefront protrusion 41 of thefastener element 21 and therear protrusion 44 of the fastener element 22 (SeeFig. 7 ). As a result of this, the left andright fastener elements front protrusion rear protrusion slider 9 as theslider 9 moves forward, as described above. - In the present embodiment, as depicted in
Fig. 6 , when a given pair of left and right fastener elements E1 and E2 included in the left andright fastener elements rear protrusion 42 of the anterior fastener element E1 of the pair of fastener elements E1 and E2 and thefront protrusion 43 of the posterior fastener element E2 of the pair of fastener elements E1 and E2, therear protrusion 44 of the posterior fastener element E2 is not in contact with thefront protrusion 41 of a fastener element E3 with which the posterior fastener element E2 came into initial contact at itsrear protrusion 44 in advance (in other words, a fastener element E3 immediately posterior to the posterior fastener element E2). For the engagement between the fastener elements E1 and E2, there is a need for therear protrusion 42 of the anterior fastener element E1 to move across thefront protrusion 43 of the posterior fastener element E2. As described above, therear protrusion 44 of the posterior fastener element E2 is not in contact with thefront protrusion 41 of the fastener element E3, namely there is a space between them. It is thus facilitated that the posterior fastener element E2 moves more freely, allowing therear protrusion 42 of the anterior fastener element E1 to more easily move across thefront protrusion 43 of the posterior fastener element E2. This allows the reduction of resistance for sliding theslider 9 forward. - The same descriptions as in
Fig. 6 would be applicable toFig. 7 . As depicted inFig. 7 , when a given pair of left and right fastener elements E0 and E1 come into initial contact on therear protrusion 44 of the anterior fastener element E0 and thefront protrusion 41 of the posterior fastener element E1, therear protrusion 42 of the posterior fastener element E1 is not in contact with thefront protrusion 43 of the fastener element E2 with which the posterior fastener element E1 came into initial contact at itsrear protrusion 42 in advance (i.e. the initial contact inFig. 6 ). There is a space between therear protrusion 42 of the fastener element E1 and thefront protrusion 43 of the fastener element E2, and the fastener element E1 can move more freely, allowing the reduction of resistance for sliding theslider 9 forward. As would be understood by comparingFigs. 6 and7 , as theslider 9 moves forward, a respective one of the fastener elements comes into initial contact with, two times in total at different time points, two fastener elements which are adjacently arranged at the opposite side in the left-right direction. - In some cases, for a purpose of effective reduction of resistance for sliding the
slider 9, therear protrusion 42 of the fastener element E1 and thefront protrusion 43 of the fastener element E2 come into contact on their respectivesloped regions 62a of the farther sloped surfaces 62. Likewise, in the case ofFig. 7 , therear protrusion 44 of the fastener element E0 and thefront protrusion 41 of the fastener element E1 come into contact on their respectivesloped regions 62a of the farther sloped surfaces 62. The rear protrusion slides on the slopedregion 62a and moves across thetop portion 63 of the front protrusion, and then enters into thefront recess 57. The front protrusion slides on the slopedregion 62a and moves across thetop portion 63 of the rear protrusion, and then enters into therear recess 58. The front protrusion and the rear recess are fitted and the rear protrusion and the front recess are fitted, thereby the left and right fastener elements E1 and E2 are engaged and the strength ofslide fastener 1 would be ensured against a lateral pulling force. In cases where thewalls slide fastener 1 against thrust in the up-down direction would be ensured. - In some cases, the fastener elements E1 and E2 come into initial contact on the center line CL of
slider 9. This initial contact point P1 is away from the rear end of thecoupling pillar 93 by a first distance D1. An intersection point P2 between the center line Cl of theslider 9 and the rear protrusion 44 (the slopedregion 62a of the farther sloped surface 62) of the fastener element E2 is away from the rear end of thecoupling pillar 93 by a second distance D2 (SeeFig. 6 ). An intersection point P3 between the center line CL of theslider 9 and the front protrusion 41 (the slopedregion 62a of the farther slopedsurface 62 described above) of the fastener element E3 is away from the rear end of thecoupling pillar 93 by a third distance D3 (SeeFig. 6 ). The intersection points P2 and P3 are intersection points at the time of initial contact between thefastener elements E 1 and E2. Equation of D1<D2<D3 is satisfied. The equation of D2<D3 indicates the existence of space between therear protrusion 44 of the fastener element E2 and thefront protrusion 41 of the fastener element E3. - The fastener elements E1 and E2 (see
Fig. 6 ) which have come into initial contact at the initial contact point away from the rear end of thecoupling pillar 93 by the first distance D1 would cease to be in contact before the next pair of fastener elements E0 and E1 for initial contact come into initial contact (seeFig. 7 ). When the pair of fastener elements E0 and E1 for the next initial contact come into initial contact, the pair of fastener elements E1 and E2 for the previous initial contact are not in contact (in more particular, there is a space between therear protrusion 42 of the fastener element E1 and thefront protrusion 43 of the fastener element E2), and the fastener element E1 can move more freely, thus reducing the resistance for sliding theslider 9. - A design can be employed which, when the pair of left and right fastener elements E0 and E1 come into initial contact on the
rear protrusion 44 of the anterior fastener element E0 thereof and thefront protrusion 41 of the posterior fastener element E1 thereof inside of theslider 9, allows therear protrusion 42 of the posterior fastener element E1 not to be in contact with thefront protrusion 43 of the fastener element E2 with which the posterior fastener element E1 came into initial contact at itsrear protrusion 42 in advance. This method of designing may include determining the initial contact position for thefastener elements attachment base front protrusion 41 and therear protrusion 42 for a purpose of adjustment of the first distance D1 or smooth engagement between the fastener elements, and may section the farther slopedsurface 62 as described above, for example. This method of designing can be performed by computer software. - Based on the above teachings, a skilled person in the art would be able to add various modifications to the respective embodiments. Reference numerals in Claims are just for reference and should not be referred for the purpose of narrowly construing the scope of claims.
