57-60773, (Japanese Utility Model Laid-Open No. 58-164290)).
[0004] In the case of the aforementioned electromagnetic wave
shield slide fastener given in FIG. 8, the electromagnetic wave
shield member as a component of the fastener tape has a special
configuration and resultantly a special manufacturing apparatus is
required in order to secure the electromagnetic wave shield
performance. Therefore, it is difficult to provide a low cost
electromagnetic wave shield slide fastener or an electromagnetic
wave shield slide fastener having good flexibility and high
quality.

[0005] An object of the present invention is, in the event of
providing a slide fastener having special performance such as
electromagnetic wave shield performance and fire-resistant
performance, to provide a slide fastener having good appearance and
good quality at a low cost by using a fastener tape not requiring a
special structure without using a fastener tape specially produced
for the slide fastener as a component of the slide fastener, and
thus cutting the product cost.
[0006] Other objects of the present invention are as follows:
[0007] To provide a slide fastener that allows a curved fastener
tape to be easily fabricated with an extremely simple structure and
does not cause sewing wrinkles for the fastener tape when the
fastener tape is sewed on a joining material;
[0008] To provide a slide fastener that allows fastener elements to
be attached to a folded part formed by folding a fastener tape
double with a simple structure and stable configuration;
[0009] To provide a slide fastener that facilitates firm attachment
of fastener elements by reinforcing the folded part formed by
folding a fastener tape double;
[0010] To provide a slide fastener that facilitates firm attachment

fastener tape so that the fastener tape can have special
performance easily; and
[0012] To provide a slide fastener that allows a fastener tape to
easily have electromagnetic wave shield performance or further
special performance such as fire-resistant performance.
[0013] In order to achieve the above objects, the present invention
employs the following configurations.
[0014] In a slide fastener according to the present invention, a
fastener element 3 is attached to a first edge part 12 of a
fastener tape 2, and the fastener tape 2 in the vicinity of the
installation part 5 of the fastener element 3 is sewn with a sewing
thread 6 continuously extending in the longitudinal direction of
the fastener tape 2.
[0015] Here, the part of the fastener tape 2, to which the fastener
element 3 is attached may be single-layered or double-layered.
[0016] In the configuration, the fastener element is attached to
the edge part of the fastener tape and vicinity area of the
installation part of the fastener element is sewn with the sewing
thread. Accordingly, the fastener tape is tightened in the
longitudinal direction thereof and thus the edge part thereof is
curved toward the inner side of the tape. Consequently, the
configuration has an effect of providing, at a low cost, a high
quality slide fastener capable of avoiding the phenomenon of a
waved fastener tape, namely sewing wrinkles, resulted from sewing
shrinkage caused when a fastener stringer is attached to a joining
material by sewing.
[0017] In a slide fastener according to the present invention, a
folded part 4 is formed by folding a first edge part 12 of a
fastener tape 2 inward to overlay the folded parts, a fastener
element 3 is attached to the folded part 4 of the overlaid
structure, and the fastener tape 2 in the vicinity of the
installation part 5 of the fastener element 3 is sewn with a sewing
thread 6 continuously extending in the longitudinal direction of
the fastener tape 2.
[0018] The configuration has an effect of reinforcing the edge part
of a fastener tape and assuring the attachment of a fastener
element in a stable state by folding the edge part of the fastener
tape inward, thus forming the folded part, and attaching the
fastener element to the folded part.
[0019] In a slide fastener according to the present invention, a
core material 8 formed in various shapes is inserted into the
folded part 4 formed at a first edge part 12 of a fastener tape 2
to reinforce the folded part 4, a fastener element 3 is attached to
the folded part 4 with the core material 8 being interposed, and
the fastener tape 2 in the vicinity of the installation part 5 of
the fastener element 3 is sewn with a sewing thread 6 continuously
extending in the longitudinal direction of the fastener tape 2.
[0020] As the core material 8, it is preferable to use a core
material 8 formed with a core string 10 attached to an edge of a
support piece 11.
[0021] The configuration has an effect of reinforcing the edge part
of a fastener tape and assuring the firm installation attachment of
a fastener element in a stable state by inserting a core material
into the folded part of the fastener tape or into the folded part
and the peripheral area thereof, and thus attaching the fastener
element with the core material being interposed. By providing a
core string to the core material, the reinforcing effect is further
enhanced.
[0022] In the slide fastener according to the present invention, it
is preferable that a fastener element 3 has a fitting head 16 and a
pair of legs 15 projecting from the fitting head 16 and the legs 15
are attached in a manner of clamping the folded part 4.
[0023] By this configuration, a fastener element can firmly be
attached to a fastener tape in a stable state even when the
fastener element is made of metal.
[0024] The fastener tape 2 of a slide fastener according to the
present invention is made of fiber and the whole body of the
fastener tape 2 is formed with a uniform structure.
[0025] According to the configuration, since a fastener tape is
made of fiber and the whole tape is formed with a uniform
structure, on applying a plating solution or a coating agent, it
uniformly infiltrates into the whole body of the tape and
resultantly electromagnetic wave shield treatment by plating and
coating treatment with a fire-resistant additive can be applied to
the fastener tape extremely easily. A preferable fastener tape is a
woven tape having a plain weave structure woven by the warp and the
weft, which has an effect of making a high quality product at a low
cost.
[0026] It is preferable that the slide fastener according to the
present invention has electromagnetic wave shield performance by
applying metal plating as a special performance mechanism onto the
surface of the fastener tape 2.
[0027] It is preferable that the slide fastener according to the
present invention has also fire-resistant performance by further
applying coating of a fire-resistant additive as a special
performance mechanism onto the surface of the fastener tape 2.
[0028] According to the configurations, electromagnetic wave shield
performance be easily secured by applying plating onto the surface
of a fastener tape, and moreover, fire-resistant performance can be
secured by applying the coating of a fire-resistant additive onto
the surface thereof, which provides an effect of making a high
quality product at a low cost can be achieved. Therefore, the
effects of the present invention are extremely significant.

BEST MODE FOR CARRYING OUT THE INVENTION
[0037] The embodiments of slide fasteners according to the present
invention are hereunder specifically explained referring to the
drawings.
[0038] FIG. 1 shows a slide fastener according to the present
invention.
[0039] As the first feature of the slide fastener, a special
performance mechanism is provided to the basic functions of the
slide faster. More specifically, in order to provide the faster
tape 2 of a fastener stringer 1 with electromagnetic wave shield
performance, metal plating is applied onto the surface of the
fastener tape 2 to form a shield coating 7. In addition, in order
to provide the fastener tape 2 further with fire-resistant
performance, the surface of the shield coating 7 formed on the
surface of the fastener tape 2 is coated with a fire-resistant
additive and thus the fire-resistant coating 7 is formed.
[0040] The second feature of the slide fastener is as follows.
Before attaching fastener elements 3 to the fastener tape 2 of a
fastener stringer 1, the fastener tape 2 is sewn with a sewing
thread 6 so that the entire part of a first edge part 12 of the
tape 2 is curved inward, as shown in FIG. 7, regardless of whether
a core material 8 is provided at the edge part 12 of the tape 2 or
not. Thus, the surface of the fastener tape 2 does not cause sewing
wrinkles when the fastener stringer 1 is attached to a joining
material. Here, in the figure, the reference numerals 20, 21 and 22
show a slider, an opener and a stopper, respectively.
[0041] As shown in FIG. 2, the fastener tape 2 of a fastener
stringer 1 is formed by a single strip of tape. The fastener tape 2
is fabricated by: producing a base material of the fastener tape 2
having a plain weave structure using a polyester-base fiber or a
polyamide-base fiber as a warp and a weft; then applying hot-dip
plating to both of the front and back surfaces of the base material
of the fastener tape 2, (for example, plating is given on both
surfaces of the fastener tape 2 by immersing the tape in melted
solution of copper and nickel); and thus forming a shield coating
7.
[0042] The reason why a plain weave structure is employed for the
fastener tape 2 used herein is that the plating solution and the
fire-resistant additive are likely to infiltrate uniformly into the
whole body of the tape 2 with its uniform structure over the whole
body, and the tape 2 can be made at a low cost. However, as a tape
with uniform structure over the whole body, not only a plain weave
structure but also other structures may be employed. For example, a
warp-knitted tape or a nonwoven fabric formed by interlacing fibers
may also be employed. In any case, it is preferable that plating or
fire-resistant additive coating is applied to the surface of a
fastener tape 2 in the state of a straight shape.
[0043] If the tape is curved, it is difficult to immerse many tapes
in a plating bath while arranging them in an orderly manner and it
is extremely difficult to process them while continuously
transferring them to coating equipment. Therefore, the fastener
tape 2 is preferably treated in the state of a straight shape.
[0044] After forming a shield coating 7 on both surfaces of a
fastener tape 2, the fastener tape 2 is sewn with the sewing thread
6 continuously extending in the longitudinal direction of the
fastener tape 2 in the vicinity of the first edge part 12, namely
in the vicinity of the installation part 5 to which a fastener
element 3 is attached. Accordingly, the fastener tape 2 is
tightened in the longitudinal direction thereof and formed into
such a shape that the edge part 12 of the fastener tape 2 is curved
inward relative to the longitudinal direction. As a type of sewing
with the sewing thread 6, the lock stitch type is preferable. The
lock stitch is simple and makes it possible to save a sewing thread
and to produce the fastener tape 2 at a low cost.
[0045] In a case of the fastener tape 2 fixed in a curved shape, as
shown in FIG. 2, at the first edge part 12 of the fastener tape 2,
a leg 15 of a coiled filament fastener element 14 into which a core
string 10 is inserted is attached to the fastener tape 2 with an
attachment thread 18 of double-ring stitch. Consequently, the
lock-stitch sewing thread 6 is disposed in the vicinity of a
connecting part 17 of the coiled filament fastener element 14. The
attachment of the fastener element 3 to the curved fastener tape 2
causes no problem because the fastener element 3 is attached while
the curved fastener tape 2 is held in the state of a straight
shape. Consequently, there is the advantage that, when the finished
curved fastener stringer 1 is sewn on a joining material, even
though a second edge part of the fastener tape 2 is tightened in
the longitudinal direction thereof by machine sewing, the
phenomenon of the wavy surface of the fastener tape 2, namely
sewing wrinkles, can be avoided.
[0046] In the present embodiment, in order to provide
fire-resistant performance to the fastener tape 2 further after the
shield coating 7 is formed on the surface of the fastener tape 2 by
plating, a fire-resistant additive such as an inorganic salt, a
halogen compound, or a phosphoric acid ester is applied by coating
onto the surface of the shield coating 7 on the fastener tape 2 and
thus the fire-resistant performance is also provided. As a
consequence, a fastener stringer 1 having both the electromagnetic
wave shield performance and the fire-resistant performance at the
same time is made.
[0047] The fire-resistant performance is not necessarily provided,
or the coating 7 of a fire-resistant additive may be formed instead
of plating. The filament fastener element 14 attached to a fastener
tape 2 is not limited to a coil shape, and a zigzag filament
fastener element 14 may be used. Here, the reference numeral 16 in
the figure shows a fitting head.
[0048] According to the present embodiment, the following
advantages can be obtained.
[0049] By attaching the fastener element 3 to the first edge part
of the fastener tape 2 and sewing the fastener tape 2 in the
vicinity of the installation part of the fastener element 3 with a
sewing thread 6, the edge part can be curved inward.
[0050] By plating the surface of the fastener tape 2 to form a
plating film and further coating the surface thereof with the
fire-resistant additive to form a coating 7, the electromagnetic
wave shield performance by plating and the fire-resistant
performance by fire-resistant additive coating are easily secured,
which has an effect of making a high quality product at a low
cost.
[0051] Herein, since the fastener tape 2 is made of fiber and
allows the plating solution and the fire-resistant additive to
infiltrate uniformly into the whole body of the tape, the treatment
of electromagnetic wave shielding by plating and the treatment of
coating of a fire-resistant additive can be applied to the fastener
tape 2 extremely easily, which has an effect of making a high
quality product at a low cost.
[0052] As explained above, the present embodiment provides the
effects of: being able to easily produce the slide fastener having
both electromagnetic wave shield performance and fire-resistant
performance by a coating 7 at a reduced production cost; and
moreover being able to provide, at low cost, the high quality slide
fastener that can avoid the phenomenon of a wavy tape, namely
sewing wrinkles, because of the curved fastener tape 2, even when
the fastener stringer 1 is attached to a joining material.
[0053] Like the aforementioned embodiments shown in FIGS. 1 and 2,
the fastener stringer 1 shown in FIG. 3 is produced by forming a
shield coating 7 on both surfaces of the fastener tape 2. It is
different from the embodiment of FIGS. 1 and 2 in the following
points.
[0054] In the present embodiment, an edge part 12 of the fastener
tape 2 is folded inward to make a folded part 4, and an end part 19
of the fastener tape 2 itself is sewn on the fastener tape 2 with a
lock stitch sewing thread 6. Then, the sewing thread 6 is stretched
to curve the fastener tape 2, and at the same time the edge part 12
is reinforced. After that, a core string 10 is inserted into a
coiled filament fastener element 14 and the fastener element 14 is
attached onto the surface of the folded part 4 of the curved
fastener tape 2 with the attachment thread 18 of double-ring
stitch. Thus the fastener stringer 1 is completed.
[0055] According to the present embodiment, the following
advantages can be obtained in addition to the advantages of the
embodiments shown in FIGS. 1 and 2.
[0056] By folding inward the first edge part of the fastener tape 2
to form the folded part 4 and attaching the fastener element 3 to
the folded part 4, the edge part of the fastener tape 2 is
reinforced and the fastener element 3 can be attached in a stable
state.
[0057] Like the aforementioned embodiment shown in FIG. 3, the
fastener stringer 1 shown in FIG. 4 is produced by forming the
folded part 4 on a fastener tape 2 of the fastener stringer 1 and
forming a shield coating 7 on both surfaces of the fastener tape 2.
It is different from the embodiment of FIG. 3 in the following
points.
[0058] In the present embodiment, the fastener tape 2 is folded to
form an overlaid part, a core material 8 formed from a sheet of
flat reinforcement 9 is inserted into the overlaid part of the
folded fastener tape 2, and thus the folded part 4 of the fastener
tape 2 is reinforced.
[0059] Here, the reinforcement 9 continuously extends in the
longitudinal direction of the fastener tape 2 and is a narrow tape
made by weaving fabric or knitting with fabrics such as polyester
fiber, polyamide fiber or the like.
[0060] The fastener tape 2 is sewn at an end part 19 thereof with a
lock stitch sewing thread 6 and formed so that the whole body of
the fastener tape 2 is curved, and thereafter, a coiled filament
fastener element 14 into which a core string 10 is inserted is
attached onto the surface of the folded part 4 with an attachment
thread 18 of double-ring stitch.
[0061] According to the present embodiment, the following
advantages can be obtained in addition to the advantages of the
embodiment shown in FIG. 3.
[0062] By inserting the core material 8 into the folded part of the
fastener tape 2 and attaching a fastener element 3 thereto with the
core material 9 (Translator's comment: the core material 8) being
interposed, the edge part of the fastener tape 2 is reinforced and
the fastener element 3 can firmly be attached in a stable
state.
[0063] Like the aforementioned embodiment shown in FIG. 3, the
fastener stringer 1 shown in FIG. 5 is produced by folding a
fastener tape 2 having electromagnetic wave shield performance by
forming a shield coating 7 or further having a fire-resistant
additive coating 7 on both surfaces of the fastener tape 2 to form
a folded part 4. It is different from the embodiment of FIG. 3 in
the following points.
[0064] In the present embodiment, a core material 8 made of a round
core string 10 produced, for example, by bunching synthetic fiber
such as polyester fiber or polyamide fiber is inserted into a
folded part 4 to form a bulgy edge part 12. The vicinity of the
edge part 12 is sewn with a lock stitch sewing thread 6 to form an
installation part 5. Then, a metal fastener element 13 including a
fitting head 16 and a pair of legs 15 projecting from the fitting
head 16 is attached to the installation part 5 and the fastener
tape 2 is formed so that the whole body thereof is curved inward as
shown in FIG. 7.
[0065] With regard to the curved fastener tape 2, the legs 15 of
the metal fastener element 13 are fixed to the bulgy edge part 12
formed by the core material 8 in a manner of clamping the bulgy
part 12 in between. In this case, they are configured so that the
sewing thread 6 is located in the vicinity of the installation part
5 of the metal fastener element 13 attached to the fastener tape 2.
Here, the fastener element 13 is not limited to a metallic one but
it may be formed by injection molding of a synthetic resin onto the
tape edge part 12 in a manner of clamping the folded part 4. The
reference numeral 16 in the figure shows a fitting head.
[0066] According to the present embodiment, same advantages with
those in the embodiment shown in FIG. 4 can be obtained.
[0067] In the fastener stringer 1 shown in FIG. 6, at the
aforementioned folded part 4 of the fastener tape 2 of the fastener
stringer 1 shown in FIG. 5, the fastener tape 2 having a shield
coating 7 on both surfaces of the tape is folded and a core
material 8 is inserted into the overlaid part of the fastener tape
2. The core material 8 is formed by folding a single sheet of
support piece 11 woven or knitted like the aforementioned
reinforcement 9 and inserting a core string 10 such as a round
string into the folded part. The fastener tape 2 is reinforced by
inserting the core material 8 into the folded part 4 and peripheral
area of the fastener tape 2 and the bulgy edge part 12 is formed at
a first edge part of the fastener tape 2. After that, an edge 19A
of the support piece 11 inserted into the folded part 4, together
with the overlaid fastener tape 2, is sewn with a sewing thread 6
to form an installation part 5 to which a fastener element 13 can
be attached. The fastener tape 2 is formed so that the whole body
thereof is curved inward as shown in FIG. 7.
[0068] That is, the fastener stringer 1 is formed by: fixing the
legs 15 of a metallic fastener element 13 to the bulgy edge part 12
of the curved fastener tape 2 in a manner of clamping the bulgy
edge part 12 in between so that the sewing thread 6 provided to the
fastener tape 2 is located in the vicinity of the legs 15 of the
fastener element 13.
[0069] According to the present embodiment, the following
advantages can be obtained in addition to the advantages of the
embodiment shown in FIG. 3.
[0070] By inserting the core material 8 having the core string 10
at the edge of the support piece 11 into the folded part 4 and the
peripheral area of the fastener tape 2 and attaching the fastener
element 3 with the core material 8 being interposed, the edge part
of the fastener tape 2 is reinforced and the fastener element 3,
particularly the single piece of metallic or resin-formed fastener
element 3, can be firmly attached in a stable state.
