[0019] As illustrated in Figs. 1 to 3, a slide fastener 70 has a left-right pair of fastener
stringers 50, and one fastener slider 60 for opening and closing the left-right pair
of fastener stringers 50. Each fastener stringer 50 has a fastener tape 10 elongated
in the front-rear direction, a fastener elements 20 aligned in the front-rear direction,
and stops 30, 30s positioned adjacent to the fastener element 20. The left-right fastener
elements 20 will be engaged one another as the fastener slider 60 moves frontward,
and the left-right fastener elements 20 will be disengaged as the fastener slider
60 moves rearward. As shown in Fig. 3, the stops 30 have been housed in the fastener
slider 60, and thus the frontward movement of the fastener slider 60 is hindered.
The stop 30 is a front stop, and the stop 30s is a rear stop.
[0020] The fastener slider 60 may have an upper wing 61, a lower wing 62, and a coupling
pillar 63. The upper wing 61 and the lower wing 62 are arranged to be opposed with
a constant interspace. The front end portion of the upper wing 61 and the front end
portion of the lower wing 62 are coupled by the coupling pillar 63. Left-right pair
of front mouths are arranged at the left and right positions of the coupling pillar
63 through which the fastener element 20 moves into the fastener slider 60 and through
which the fastener element 20 moves out of the fastener slider 60 from the inside
thereof. At least one of the upper wing 61 and the lower wing 62 may be provided with
left-right pair of flanges 64. An element passage may be defined between the left
or right flange 64 and the coupling pillar 63. Y-shaped element passage may be defined
inside of the fastener slider 60. The fastener slider 60 may be made of a metal or
a resin. The upper wing 61 of the fastener slider 60 may be provided with a pull tab
attachment pillar 65, and a pull tab 66 may be attached to the pull tab attachment
pillar 65.
[0021] Each one of the left-right paired fastener tapes 10 has a tape side-edge portion
15 being opposed to the other one of the fastener tapes 10, and the tape side-edge
portion 15 extends along the elongated direction of the fastener tape 10, i.e. along
the front-rear direction. The tape side-edge portion 15 is provided with a core thread
16. Likewise of the tape side-edge portion 15, the core thread 16 extends in the elongated
direction of the fastener tape 10, i.e. front-rear direction. In the illustrated exemplary
embodiment, the core thread 16 is provided across the tape side-edge portion 15 in
the front-rear direction. In other embodiments, the core thread 16 may be provided
in a part of the tape side-edge portion 15 in the front-rear direction, i.e. not provided
across the whole region thereof.
[0022] In some embodiments, the fastener tape 10 may be a flexible cloth in which longitudinal
warps and a lateral warp are woven, and may have an upper surface and a lower surface
defining its thickness. The fastener tape 10 may have a tape main portion 14 and a
tape side-edge portion 15, and the tape side-edge portion 15 is provided with the
core thread 16. The core thread 16 may include one or more or two or more yarns extending
in the front-rear direction, and may be secured to the tape side-edge portion 15 by
being woven thereto. The core thread 16 may include a core thread top 16m projecting
upward from the upper surface of the fastener tape 10 and a core thread bottom 16n
projecting downward from the lower surface of the fastener tape 10.
[0023] In the illustrated exemplary embodiment, the fastener elements 20 are metal elements.
The fastener elements 20 may be arranged at constant intervals in the front-rear direction
along the tape side-edge portion 15 of the fastener tape 10, i.e. along the core thread
16 in particular. In other embodiment, the fastener element 20 may be a coil element
in which a monofilament is wound helically, and may be sewn to the tape side-edge
portion 15 of the fastener tape 10. In some embodiments, the core thread 16 may be
provided inside of the coil element, and in other embodiments, the core thread 16
is not provided in the coil element. In yet other embodiments, the fastener elements
20 may be resin elements.
[0024] The stop 30 may be a metal stop and may be secured to the core thread 16 of the tape
side-edge portion 15 of the fastener tape 10 through a swaging process. As shown in
Figs. 4 to 6, the stop 30 may be configured to sandwiches the core thread 16 of the
tape side-edge portion 15 of the fastener tape 10, i.e. may have a first leg 35 at
the upper surface side of the fastener tape 10, a second leg 36 at the lower surface
side of the fastener tape 10, and a coupling portion 37 that couples the first leg
35 and the second leg 36. The first leg 35 may touch the core thread top 16m at the
tape side-edge portion 15 and the second leg 36 may touch the core thread bottom 16n
at the tape side-edge portion 15.
[0025] The core thread 16 of the tape side-edge portion 15 of the fastener tape 10 is held
by and between the first leg 35 and the second leg 36, ensuring that the stop 30 is
secured to the core thread 16 of the tape side-edge portion 15 of the fastener tape
10. The first leg 35 of the stop 30 may be referred to as an upper leg and the second
leg 36 of the stop 30 may be referred to as a lower leg.
[0026] The coupling portion 37 may be provided outwardly of fastener tape relative to the
first leg 35 and the second leg 36. The direction of outwardly of fastener tape may
be a direction directed from a position on the surface of the fastener tape to a position
outside of the fastener tape and, for example, may be a direction crossing the core
thread from a position on the surface of the fastener tape to a position outside of
the fastener tape. The first leg 35 and the second leg 36 are provided inwardly of
fastener tape relative to the coupling portion 37. The direction of inwardly of fastener
tape may be a direction directed from a position outside of the fastener tape to a
position on the surface of the fastener tape and, for example, may be a direction
crossing the core thread from a position outside of the fastener tape to a position
on the surface of the fastener tape.
[0027] The coupling portion 37 may be positioned inwardly in the left-right direction relative
to the first leg 35 and the second leg 36. Inwardly and outwardly in the left-right
direction may be a direction recognized on the basis of the left-right pair of fastener
stringers 50. For the closed left-right fastener stringers 50, the directions of inwardly
and outwardly in the left-right direction can be described as follows. The inwardly
in the left-right direction may be a direction directed to the engaged left-right
fastener element lines in the left-right direction. The outwardly in the left-right
direction may be a direction directed away from the engaged left-right fastener element
lines.
[0028] As schematically shown in Fig. 7, sufficient spacing is provided between the first
leg 35 and the second leg 36 of the stop 30 before being swaged and deformed so that
the core thread 16 of the tape side-edge portion 15 can be easily inserted into the
space between the first leg 35 and the second leg 36. After the core thread 16 has
been provided in the space between the first leg 35 and the second leg 36, the stop
30 may be plastically deformed so that the distance between the first leg 35 and the
second leg 36 will be reduced.
[0029] The stop 30 may have a first outer surface 31 and second outer surface 32 that crosses
the up-down direction. The first outer surface 31 is positioned at the same side as
the upper surface of the fastener tape 10 in the up-down direction, and the second
outer surface 32 is positioned at the same side as the lower surface of the fastener
tape 10 in the up-down direction. The first outer surface 31 and the second outer
surface 32 may sandwich the tape side-edge portion 15 and the core thread 16 and may
face in opposite directions in the up-down direction. The first outer surface 31 and
the second outer surface 32 have a width in the left-right direction, and a length
in the front-rear direction. Each of the first outer surface 31 and the second outer
surface 32 extends in the front-rear direction while having a substantially constant
width.
[0030] The core thread 16 of the tape side-edge portion 15 may be provided between the first
outer surface 31 and the second outer surface 32. The thickness TH30 of the stop 30
may be defined by the first outer surface 31 and the second outer surface 32. Each
of the first outer surface 31 and the second outer surface 32 may occupy a rectangular
region when viewed in elevation as illustrated in Figs. 1 to 3. In other words, each
rim of the first outer surface 31 and the second outer surface 32 extends to draw
a rectangular. In other embodiments, the first outer surface 31 and the second outer
surface 32 each may have a shape viewed in elevation different from the illustrated
one. Note that the first outer surface 31 may be referred to as a upper surface, and
the second outer surface 32 may be referred to as a lower surface.
[0031] The stop 30 may have a connection surface 33 that extends in the up-down direction
and interconnects the first outer surface 31 and the second outer surface 32. The
connection surface 33 may be provided outwardly of fastener tape relative to the core
thread 16 of the fastener tape 10. The connection surface 33 may connect the respective
rims of the first outer surface 31 and the second outer surface 32 which are positioned
inwardly in the left-right direction. The connection surface 33 may have a width in
the up-down direction and may have a length in the front-rear direction. The connection
surface 33 may extend in the front-rear direction while having a constant width in
the up-down direction. The connection surface 33 may be oriented to be crossing or
normal to the left-right direction. The connection surface 33 may be a surface that
can touch the coupling pillar 63 of the fastener slider 60.
[0032] The stop 30 may have an opposite surface 34 positioned at the opposite side of the
connection surface 33 in the left-right direction. The opposite surface 34 is provided
inwardly of fastener tape relative to the core thread 16 of the fastener tape 10.
The opposite surface 34 is divided by the fastener tape 10. The opposite surface 34
may be oriented to be crossing or normal to the left-right direction. Unlike the connection
surface 33, the opposite surface 34 is provided over the fastener tape 10.
[0033] Specifically, the opposite surface 34 of the stop 30 may include a terminal surface
34m of the first leg 35 extending inwardly of fastener tape from the coupling portion
37 and a terminal surface 34n of the second leg 36 extending inwardly of fastener
tape from the coupling portion 37. The terminal surface 34m of the first leg 35 may
be oriented substantially normal to the upper surface of the fastener tape, and the
terminal surface 34n of the second leg 36 may be oriented substantially normal to
the lower surface of the fastener tape.
[0034] The stop 30 may include a first end surface 301 and a second end surface 302 which
extend in the up-down direction to couple the first outer surface 31 and the second
outer surface 32, and the first end surface 301 and a second end surface 302 are oriented
to face in opposite directions one another in the front-rear direction. The first
end surface 301 and the second end surface 302 are provided to cross the core thread
16 of the fastener tape 10. The first end surface 301 may be referred to as a front
end surface, and the second end surface 302 may be referred to as a rear end surface.
The first end surface 301 couples the front-side of the rim of the first outer surface
31 and the front-side of the rim of the second outer surface 32. The second end surface
302 couples the rear-side of the rim of the first outer surface 31 and the rear-side
of the rim of the second outer surface 32.
[0035] It should be noted that the first outer surface 31 may be a surface across the first
leg 35 and the coupling portion 37. Likewise, the second outer surface 32 may be a
surface across the second leg 36 and the coupling portion 37. The connection surface
33 may be one side surface of the coupling portion 37. The connection surface 33 of
the stop 30 may be a surface to be opposed to the other one of paired stops 30, and
thus it could be referred to as an opposed surface.
[0036] The stop 30 may include two ends 48 of the first end portion 38e and the second end
portion 38g in a direction along the core thread 16, i.e. the front-rear direction,
and an intermediate portion 39 between the two ends 38. The first end portion 38e
may be referred to as a front end portion, and the second end portion 38g may be referred
to as a rear end portion. The first end portion 38e of the stop 30 may be positioned
farther away from the fastener element 20 than the second end portion 38g. The second
end portion 38g of the stop 30 may be positioned closer to the fastener element 20
than the first end portion 38e and may be positioned adjacent to the fastener element
20.
[0037] In a non-limiting example, the length L38e of the first end portion 38e along the
core thread 16, the length L38g of the second end portion 38g along the core thread
16, the length L39 of the intermediate portion 39 along the core thread 16 may be
as follows. L38e=1.43mm, L38g=1.43mm, L39=0.94mm. In this case, the length L30 of
the stop 30 along the core thread 16 is 3.8mm. In some embodiments, L38e>L39 is satisfied
and L38g>L39 is satisfied, thereby suitably realizing the balancing between appearance
of the stop 30 and the attachment strength. In some embodiments, the length L39 of
the intermediate portion 39 included in the length L30 of the above-described stop
30 is about 25% to 40%. In other words, (L39/L30)
∗100=25 to 40 may be satisfied in some embodiments, thereby suitably realizing the
balancing between appearance of the stop 30 and the attachment strength.
[0038] In the present embodiment, the first end portion 38e of the stop 30 may be provided
with a first slant surface 41 extending along the core thread 16 to reach the front
side of the rim of the first outer surface 31 while being gradually closer to the
core thread 16 and a second slant surface 42 extending along the core thread 16 to
reach to the front side of the rim of the second outer surface 32 while being gradually
closer to the core thread 16. In the illustrated example, the respective slant degrees
of the first slant surface 41 and the second slant surface 42 are equal one another.
In the stop 30 provided with the first slant surface 41 and the second slant surface
42, the thickness TH38 of the first end portion 38e at the front extremity is less
than the thickness TH39 of a portion of the stop 30 other than the first end portion
38e, i.e. the thickness TH39 of the intermediate portion 39 in the illustrated example.
Accordingly, sufficient attachment strength of the stop 30 to the core thread 16 may
be achieved without greatly deforming the stop 30 plastically.
[0039] Note that the tape side-edge portion 15 and the core thread 16 are provided between
the first slant surface 41 and the second slant surface 42. Furthermore, the up-down
distance between the first slant surface 41 and the second slant surface 42 may be
gradually reduced as the first slant surface 41 extends toward the rim of the first
outer surface 31 and the second slant surface 42 extends toward the rim of the second
outer surface 32. The first slant surface 41 in the first outer surface 31 extends
towards a side away from the fastener element 20 in the front-rear direction to reach
the rim of the first outer surface 31. Also, the second slant surface 42 in the second
outer surface 32 extends towards a side away from the fastener element 20 in the front-rear
direction to reach the rim of the second outer surface 32. The thickness TH30 of the
stop 30 may be reduced gradually from the intermediate portion 39 towards the front
extremity of the first end portion 38e, thus deterioration of the appearance is thus
prevented.
[0040] The first end portion 38e of the stop 30 provided with the first slant surface 41
and the second slant surface 42 may be an end portion of the stop 30 being positioned
farther away from the fastener element 20 along the core thread 16. Therefore, when
frontward movement of the fastener slider 60 is prevented, the stop 30 may be able
to sufficiently withstand a force applied from the fastener slider 60.
[0041] As shown in Fig. 6, the first end portion 38e may have a first slant inner surface
41k that slants corresponding to the first slant surface 41 and a second slant inner
surface 42k that slants corresponding to the second slant surface 42. Thus, the first
end portion 38e may have first and second edge portions 35m, 35n that bite into the
core thread 16. The first leg 35 has a first edge portion 35m that bites into the
core thread top 16m in accordance with the first slant surface 41 and the first slant
inner surface 41k. Likewise, the second leg 36 has a second edge portion 35n that
bites into the core thread bottom 16n in accordance with the second slant surface
42 and the second slant inner surface 42k. Due to the first edge portion 35m and the
second edge portion 35n, the distance between the front end portion 35e of the first
leg 35 and the front end portion 36e of the second leg 36 is reduced. The first slant
inner surface 41k of the front end portion 35e of the first leg 35 is a contact surface
that touches the core thread 16. The second slant inner surface 42k of the front end
portion 36e of the second leg 36 is a contact surface that touches the core thread
16.
[0042] Still further, in the present embodiment, a second end portion 38g of the stop 30
is provided with a third slant surface 43 extending along the core thread 16 to reach
the rear side of the rim of the first outer surface 31 while being gradually closer
to the core thread 16 and a fourth slant surface 44 extending along the core thread
16 to reach to the rear side of the rim of the second outer surface 32 while being
gradually closer to the core thread 16. In the illustrated example, the respective
slant degrees of the third slant surface 44 and the fourth slant surface 44 are equal
one another. In the stop 30 being provided with the third slant surface 43 and the
fourth slant surface 44, the thickness TH38 of the second end portion 38g at the rear
extremity is less than the thickness TH39 of an intermediate portion 39 between the
first end portion 38e and the second end portion 38g. Accordingly, the stop 30 may
be more sufficiently secured to the core thread 16, and symmetry appearance of the
stop 30 in the left-right direction may be further ensured.
[0043] Note that the tape side-edge portion 15 and the core thread 16 are provided between
the third slant surface 43 and the fourth slant surface 44. The up-down distance between
the third slant surface 43 and the fourth slant surface 44 may be gradually reduced
as the third slant surface 43 extends toward the rim of the first outer surface 31
and the fourth slant surface 42 extends toward the rim of the second outer surface
32. The third slant surface 43 extends towards a side closer to the fastener element
20 and reaches the rim of the first outer surface 31. The fourth slant surface 44
extends towards a side closer to the fastener element 20 and reaches the rim of the
second outer surface 32. The thickness TH30 of the stop 30 may be reduced gradually
from the intermediate portion 39 towards the rear extremity of the second end portion
38g, thus deterioration of the appearance is thus prevented.
[0044] In a case where the third slant surface 43 and the fourth slant surface 44 are provided
at the stop 30 additionally to the first slant surface 41 and the second slant surface
42, the respective thicknesses TH38 at the both ends 38 of the stop 30 along the core
thread 16 in the front-rear direction are less than the thickness TH39 of the intermediate
portion 39 between the both ends 38. Accordingly, sufficient attachment strength of
the stop 30 to the core thread 16 may be achieved without greatly deforming the stop
30 plastically.
[0045] As shown in Fig. 6, the second end portion 38g is provided with a third slant inner
surface 43k that slants corresponding to the third slant surface 43 and a fourth slant
inner surface 44k that slants corresponding to the fourth slant surface 44. Thus,
the second end portion 38g may have third and fourth edge portions 35p, 35q that bite
into the core thread 16. The first leg 35 has the third edge portion 35p that bites
into the core thread top 16m in accordance with the third slant surface 43 and the
third slant inner surface 43k. Likewise, the second leg 36 has a fourth edge portion
35q that bites into the core thread bottom 16n in accordance with the fourth slant
surface 44 and the fourth slant inner surface 44k. Due to the third edge portion 35p
and the fourth edge portion 35q, the distance between the rear end portion 35g of
the first leg 35 and the rear end portion 36g of the second leg 36 is reduced. The
third slant inner surface 43k of the rear end portion 35g of the first leg 35 is a
contact surface that touches the core thread 16. The fourth slant inner surface 44k
of the rear end portion 36g of the second leg 36 is a contact surface that touches
the core thread 16.
[0046] The first leg 35 may have an intermediate inner surface 45k between the above-described
first and third slant inner surfaces 41k, 43k which are respectively provided at the
front end portion 35e and the rear end portion 35g of the first leg 35. The intermediate
inner surface 45k also touches the core thread top 16m. The second leg 36 may have
an intermediate inner surface 46k between the above-described second and fourth slant
inner surfaces 42k, 44k which are respectively provided at the front end portion 36e
and the rear end portion 36g of the second leg. The intermediate inner surface 46k
also touches the core thread bottom 16n. Note that the inner surface of the first
leg 35 and the inner surface of the second leg 36 are surfaces being opposed and sandwiching
the core thread 16. The inner surface of the first leg 35 may be referred to as a
first inner surface, and the inner surface of the second leg 36 may be referred to
as a second inner surface.
[0047] In the illustrated exemplary embodiment, the stop 30 is provided with all of the
first slant surface 41, the second slant surface 42, the third slant surface 43, and
the fourth slant surface 44. However, it is envisaged that only one of the first pair
of the first slant surface 41 and the second slant surface 42 and the second pair
of the third slant surface 43 and the fourth slant surface 44 is employed in other
embodiments. That is, there is no requirement to employ both of that pairs. In other
embodiments, the first slant surface 41 and the second slant surface 42 can be omitted,
and the third slant surface 43 and the fourth slant surface 44 may be employed. In
this case, only two slant surfaces of the third slant surface 43 and the fourth slant
surface 44 in total are provided at the stop 30, and thus the
"third" slant surface will be named as a
"first" slant surface, and the
"fourth" slant surface will be named as a
"second" slant surface.
[0048] As understood from the schematic view of Fig. 6, the first slant surface 41 is provided
in the first outer surface 31 of the stop 30, and accordingly the front end portion
35e of the first leg 35 slants frontward downward. The second slant surface 42 is
provided in the second outer surface 32 of the stop 30, and accordingly the front
end portion 36e of the second leg 36 slants frontward upward. The distance between
the front end portion 35e of the first leg 35 and the front end portion 36e of the
second leg 36 may be sufficiently reduced so that the core thread 16 may be firmly
held by and between the two.
[0049] As understood from the schematic view of Fig. 6, the third slant surface 43 is provided
in the first outer surface 31 of the stop 30, and accordingly the rear end portion
35g of the first leg 35 slants rearward downward. The fourth slant surface 44 is provided
in the second outer surface 32 of the stop 30, and accordingly the rear end portion
36g of the second leg 36 slants rearward upward. The distance between the rear end
portion 35g of the first leg 35 and the rear end portion 36g of the second leg 36
may be sufficiently reduced so that the core thread 16 may be firmly held by and between
the two.
[0050] An intermediate portion 35f is provided between the front end portion 35e and the
rear end portion 35g of the first leg 35, and an intermediate portion 36f is provided
between the front end portion 36e and the rear end portion 36g of the second leg 36.
The distance between the intermediate portion 35f of the first leg 35 and the intermediate
portion 36f of the second leg 36 may be set sufficiently large.
[0051] The stop 30 may have the minimum thickness TH30min at the first end portion 38e and
the second end portion 38g. The stop 30 may have the maximum thickness TH30max at
the intermediate portion 39 between the first end portion 38e and the second end portion
38g.
[0052] As illustrated in Fig. 6, the stop 30 may be positioned adjacent to the fastener
element 20. In the illustrated exemplary embodiment, the stop 30 is positioned next
to the front end of the fastener element line. It is envisaged that the stop 30 is
positioned next to the rear end of the fastener element line in other embodiments.
As discussed above, the fastener elements 20 may be metal elements. A skilled person
would appreciate that the fastener element 20 may have a first leg 21, second leg
22, and a coupling portion coupling the first leg 21 and the second leg 22, likewise
of the stop 30. The core thread 16 is positioned between the first outer surface 21m
of the first leg 21 and the second outer surface 22m of the second leg 22. The thickness
TH20 of the fastener element 20 may be defined by the first outer surface 21m of the
first leg 21 and the second outer surface 22m of the second leg 22.
[0053] In some embodiments, the minimum thickness TH30min of the first end portion 38e and
the second end portion 38g of the above-described stop 30 may be less than the thickness
TH20 of the fastener element 20. In some embodiments, the minimum thickness TH30min
of the first end portion 38e and the second end portion 38g of the above-described
stop 30 may be equal to the thickness TH20 of the fastener element 20.
[0054] Note that the fastener element 20 have a base provided inwardly of fastener tape,
and an engagement head provided outwardly of fastener tape. Fig. 6 illustrates a sectional
configuration of the base of the fastener element 20.
[0055] As would be appreciated with reference to Fig. 4, relatively large projection and/or
recess is not formed in the first outer surface 31 of the stop 30, and the first outer
surface 31 is configured mainly from the slant surfaces and the flat surface. The
above-described first slant surface 41 and the third slant surface 43 are provided
in the first outer surface 31 and a flat surface 45 is provided between them. A slant
surface 471 and a slant surface 473 are provided outwardly of fastener tape relative
to the first slant surface41, the flat surface45, and third slant surface 43. The
slant surface 471 may be steeper than the slant surface 473. The slant surface 473
slants moderately and may be substantially flat in some embodiments. In some embodiments,
the boarder between the slant surface 471 and the slant surface 473 is not clearly
visible. Note that the second outer surface 32 may be provided with the above-described
second slant surface 42 and the fourth slant surface 44, and the flat surface 46 is
provided between them. A slant surface 472 and a slant surface 474 are provided outwardly
of fastener tape relative to the second slant surface42, the flat surface 46, and
the fourth slant surface44. The slant surface 472 may be steeper than the slant surface
474. The slant surface 474 slants moderately and may be substantially flat in some
embodiments. In the illustrated example, the flat surfaces 45, 46 are surfaces in
parallel to the fastener tape 10.
[0056] In the present embodiment, the attachment strength of the stop 30 to the core thread
16 is secured without relying on the projection or recess provided on the stop 30.
In the present embodiment, the attachment strength of the stop 30 to the core thread
16 is secured by the core thread 16 being sandwiched by the first leg 35 and the second
leg 36 at the first end portion 38e of the stop 30 based on the formation of the above-described
first slant surface 41 and the second slant surface 42 and/or by the core thread 16
being sandwiched by the first leg 35 and the second leg 36 at the second end portion
38g of the stop 30 based on the formation of the above-described third slant surface
43 and the fourth slant surface 44. No relatively large projection or recess is formed
at the stop 30, thus the appearance of the stop 30 is secured. By providing the pair
of the first slant surface 41 and the second slant surface 42 or the pair of the third
slant surface 43 and the fourth slant surface 44, self-alignment of the stop 30 may
be facilitated before being swaged in a swaging apparatus when the stop 30 is attached
to the core thread 16 by swaging as described below.
[0057] As shown in Fig. 4, the left-right width of the first slant surface 41 may increase
as being away from the flat surface 45. The left-right width of the third slant surface
43 may increase as being away from the flat surface 45. Similarly, the left-right
width of the second slant surface 42 may increase as being away from the flat surface
46. The left-right width of the fourth slant surface 44 may increase as being away
from the flat surface 46. In some embodiments, the left-right width of the first slant
surface 41 may increase to be equal to or greater than 1/2 (one half) of the left-right
width of the core thread 16. The same applies to the third slant surface. The left-right
width of the second slant surface 42 may also increase to be equal to or greater than
1/2 (one half) of the left-right width of the core thread 16. The same applies to
the fourth slant surface 44. In such embodiments, attachment strength of the stop
30 to the core thread 16 may be improved.
[0058] In some embodiments, the first slant surface 41 may be arranged above a portion R16
of the core thread 16 which has the maximum thickness. The same applies to the third
slant surface. The first slant surface 42 may be arranged above a portion R16 of the
core thread 16 which has the maximum thickness. The same applies to the fourth slant
surface. In such arrangements, attachment strength of the stop 30 to the core thread
16 may be improved.
[0059] In some embodiments, the first slant inner surface 41k touches a portion of the core
thread 16 which has the maximum thickness. The same applies to the third slant inner
surface. The second slant inner surface 42k touches a portion of the core thread 16
which has the maximum thickness. The same applies to the fourth slant inner surface
44k. In such arrangements, attachment strength of the stop 30 to the core thread 16
may be improved.
[0060] The stop 30 before being swaged may be attached to the core thread 16 of the tape
side-edge portion 15 of the fastener tape 10 through swaging using a swaging apparatus
80 shown in Fig. 8. The swaging apparatus 80 may have a first arm 83 in which a first
press part 81 for pressing the first leg 35 of the stop 30 is provided at the terminal,
and a second arm 84 in which a second press part 82 for pressing the second leg 36
of the stop 30 is provided at the terminal. The first arm 83 and the second arm 84
are axially coupled via a coupling axis 85, and can pivot one another. Before being
swaged, the stop 30 may be thrown in between the first press part 81 and the second
press part 82 and may be held temporarily. During the process of swaging, the first
arm 83 and the second arm 84 rotates in opposite directions so that the first press
part 81 moves closer to the second press part 82, the second press part 82 moves closer
to the first press part 81, resulting in that the distance between the first press
part 81 and the second press part 82 is reduced and, in turn, the core thread 16 is
held sufficiently between the first leg 35 and the second leg 36 of the stop 30.
[0061] The first press part 81 may have a pressing surface 81m for pressing the first leg
35 of the stop 30, and this pressing surface 81m may be provided with two sloped surfaces
for forming the first slant surface 41 and the third slant surface 43. A flat surface
may be provided between these two sloped surfaces for forming the flat surface 45.
The pressing surface 81m may be configured to form the above-described slant surface
471 and the slant surface 473 in the first outer surface 31.
[0062] The second press part 82 may have a pressing surface 82m for pressing the second
leg 36 of the stop 30, and this pressing surface 82m may be provided with two sloped
surfaces for forming the second slant surface 42 and the fourth slant surface 44.
A flat surface may be provided between these two sloped surfaces for forming the flat
surface 46. The pressing surface 82m may be configured to form the above-described
slant surface 472 and the slant surface 474 in the second outer surface 32.
[0063] While the stop 30 is held temporarily between the first press part 81 and the second
press part 82 as illustrated in Fig. 9(a), the stop 30 may possibly be not oriented
as intended between the two. In the present embodiment, the pressing surface 81m of
the first press part 81 is provided with the sloped surface, and the pressing surface
82m of the second press part 82 is provided with the sloped surface so that correct
orientation of the stop 30 while being swaged may possibly be facilitated as shown
in Fig. 9(b). This may ensure the self-alignment of the stop 30. Note that there is
no need to provide two sloped surfaces in the pressing surface 81m, 82m. In some embodiments,
only the sloped surface for forming the first slant surface 41 is provided at the
first press part 81, and only the sloped surface for forming the second slant surface
42 is provided at the second press part 82. Even in this case, the self-alignment
of stops may be achieved.
[0064] In the stop 30z according to a comparative example shown in Fig. 10, any one of the
first to fourth slant surfaces is not formed in the first outer surface 31 and the
second outer surface 32. A swaging apparatus 80z shown in Fig. 11 is one for producing
the stop 30z shown in Fig. 10. Sloped surfaces for forming the first slant surface
41 and the third slant surface 43 are not provided in the first press part 81 of the
swaging apparatus 80z shown in Fig. 11. Similarly, sloped surfaces for forming the
second slant surface 42 and the fourth slant surface 44 are not provided in the second
press part 82. Thus, the self-alignment of stops 30 as described with reference to
Fig. 9 may not be promoted, possibly inviting the lowered attachment strength of the
stop 30 to the core thread 16.
<Second Embodiment
[0065] A second embodiment will be discussed with reference to Fig. 12. Fig. 12 is a schematic
sectional view of a stop included in a fastener stringer, additionally illustrating
a sectional configuration of a fastener element adjacent to the stop. In the present
embodiment, the first slant surface 41 is provided across the entire length of the
stop 30 in the front-rear direction, and the second slant surface 42 is provided across
the entire length of the stop 30 in the front-rear direction. Even in this case, the
same effects will be obtained with the first embodiment. The stop 30 has the minimum
thickness at the first end portion 38e and the maximum thickness at the second end
portion 38g.
<Further comparative example>
[0066] In the stop 30zz according to a comparative example shown in Fig. 13, two recesses
305 are formed in the first outer surface 31, and two recesses 305 are similarly formed
in the second outer surface 32. In this case, it is required to give relatively larger
deformation to the stop 30. Such a large deformation is not always acceptable. The
self-alignment of stops 30 at the swaging apparatus 80 may not be possible either.
<Further embodiment
[0067] Fig. 14 is a schematic partial perspective view of a rear stop 30s in Fig. 1. The
rear stop 30s has the identical configuration with the front stop 30 of Fig. 1. In
particular, this rear stop 30s is provided with a first outer surface and a second
outer surface facing in opposite directions and sandwiching the core thread of the
tape side-edge portion. A first end of the stop in a direction along the core thread
is provided with a first slant surface extending along the core thread to reach to
a rim of the first outer surface while being gradually closer to the core thread and
a second slant surface extending along the core thread to reach to a rim of the second
outer surface while being gradually closer to the core thread. The thickness of the
first end of the stop being provided with the first slant surface and the second slant
surface is less than a thickness of a portion of the stop other than said first end.
The above-described other features of the front stop 30 may be similarly applicable
to the rear stop 30s illustrated in Fig. 1 and 14. That is, the stops of the present
disclosure should not be limited to the front stop and would be usable for the rear
stop.
[0068] Given the above teachings, a skilled person in the art would be able to add various
modifications to the respective embodiments. Reference codes included in claims are
just for reference and should not be referenced for purposes of narrowly construing
the scope of claims.
