Description
TECHNICAL FIELD
[0001] The present invention relates to a slider for a slide
fastener, and more particularly, to a slider for a slide fastener
to be attached to a jacket for use in cold regions, the slider
having the function of preventing cold feeling.
BACKGROUND
[0002] In a case where a slider for a slide fastener to be attached
to a jacket such as a ski suit for use in cold regions is made of
metal, when the slider directly touches the skin (e.g. the neck, a
shoulder or the chin) of a user in a cold atmosphere, the user has
cold feeling and feels uncomfortable. As a countermeasure, the
slider is subjected to cold feeling preventive treatment to have
the function of preventing cold feeling.
[0003] For instance, Patent Document 1 discloses a configuration
for imparting the function of reducing cold feeling to a metal
fastener slider. Specifically, a cover is attached to a lower blade
of a slider body, and a space is defined between the lower surface
of the lower blade and the plane of the cover. Since air having
high heat insulation property is sealed inside this space, direct
transfer of the low temperature of the slider body to the skin is
prevented or slowed down.
[0004] In addition, Patent Document 2 discloses attaching extremely
short fibers of, for example, silk, hair, cotton or synthetic
fiber, to the entire surface of a slider body by electro-deposition
fiber implantation or using an adhesive in order to improve
decorative properties. Although this slider is not dedicated to
reduce cold feeling, its function of reducing cold feeling is
effective to a certain level.
[0005] Although the slider having the function of reducing cold
feeling disclosed in Patent Document 1 above can realize the effect
of preventing or slowing down the direct transfer of the low
temperature of the slider body to the skin, the effect of reducing
cold feeling may significantly decrease when a long time has
passed. In addition, since the cover is attached to the slider, it
is required to form an engaging portion for fixing the cover to the
slider body, thereby making it difficult to suppress fabrication
time, cost, or the like. In addition, the major component of the
cover material is a resin material, which gives cold feeling in
extremely cold regions or the like.
[0006] Although the slider disclosed in Patent Document 2 can
realize the function of reducing cold feeling in a certain level,
when the jacket with the slider attached thereto is washed several
times, the short fibers attached to the slider are stripped off,
thereby causing the problem of insufficient durability.

SUMMARY
[0009] It is therefore an object of the present invention to
provide a slider for a slide fastener which rarely gives cold
feeling even when the back surface of the slider for the slide
fastener touches the skin (in particular, the neck, a shoulder, the
chin, or the like) of a person in the case in which, for example, a
jacket with the slide fastener attached thereto is used for a long
time in cold regions. In addition, the slider has high durability
and is fabricated at a low cost.
[0010] In order to achieve the above object, according to an aspect
of the embodiments of the present invention, there is provided a
slide for a slide fastener comprising a slider body which includes:
an upper blade disposed at a front side of the slider body, which
is a pull-tab attachment side; a lower blade disposed at a back
side of the slider body, which is opposite to the front side; and a
connecting post connecting the upper blade and the lower blade to
each other, wherein a fibrous fabric sheet is integrally fixed to a
back surface of the lower blade at the back side, with an adhesive
layer being interposed between the fibrous fabric sheet and the
back surface of the lower blade.
[0011] According to the above configuration, it is possible to
impart the function of preventing cold feeling to existing sliders
at a low cost without adapting the slider body to a special
shape.
[0012] In addition, since a member for preventing cold feeling is
the fibrous fabric sheet, the member does not become cold even
after the elapse of a long time. Therefore, when the member
partially touches the skin of the neck or the like, the member
rarely gives cold feeling.
[0013] Furthermore, since the fibrous fabric sheet is a
sheet-shaped article, the fibrous fabric sheet is not easily
released from the slider body, thereby obtaining high
durability.
[0014] In the slider, a circumferential portion of the back surface
of the lower blade may be exposed without being covered with the
fibrous fabric sheet.
[0015] According to the above configuration, since the fibrous
fabric sheet is not present at least on the circumference of the
back surface of the slider body, it is possible to reduce the
possibility that the fibrous fabric sheet may be stripped off from
the end portion thereof, thereby improving the durability of the
slider with the function of preventing cold feeling.
[0016] In the slider, the back surface of the lower blade may
comprise a chamfered portion at a circumferential portion thereof,
the chamfered portion being curved or inclined so as to come close
to the upper blade toward the outside of the slider body, and a
flat surface surrounded by the chamfered portion, and the fibrous
fabric sheet may be fixed to the flat surface.
[0017] According to the above configuration, since the
circumferential edge portion of the fibrous fabric sheet does not
extend outward beyond the circumference of the back surface of the
lower blade, it is possible to reduce the possibility that the
fibrous fabric sheet may be stripped off from the end portion
thereof, thereby improving the durability of the slider with the
function of preventing cold feeling.
[0018] In addition, since the circumferential portion of the back
surface of the lower blade is chamfered such that the
circumferential portion is curved or inclined toward the upper
blade, the circumferential portion of the lower blade rarely
touches the neck or the like. This consequently lowers the
possibility that the circumferential portion may touch the skin and
give cold feeling to the skin.
[0019] In the slider, the fibrous fabric sheet may not protrude
toward the outside of the slider body beyond the adhesive
layer.
[0020] According to the above configuration, it is possible to
prevent the fibrous fabric sheet from being stripped off from the
end portion while strongly bonding the fibrous fabric sheet to the
slider body.
[0021] In the slider, the adhesive layer may be formed of an
adhesive or an adhesive sheet, and the adhesive may be an
epoxy-based adhesive.
[0022] According to the above configuration, the adhesive layer may
be formed of a liquid adhesive or a sheet-shaped adhesive. In
addition, the adhesive may be implemented as an epoxy-based
adhesive. Since the epoxy-based adhesive has strong bonding force
and can withstand low temperature, the fibrous fabric sheet and the
slider body can be strongly bonded to each other.
[0023] In the slider, the adhesive may fix the fibrous fabric sheet
by penetrating between fibers of the fibrous fabric sheet from a
first surface of the fibrous fabric sheet, which faces the adhesive
layer.
[0024] According to the above configuration, since some of the
fibers exposed on the first surface of the fibrous fabric sheet,
that faces the adhesive layer are buried in the adhesive, the
fibrous fabric sheet and the slider body can be strongly bonded to
each other.
[0025] In the slider, the adhesive may not exude from a second
surface of the fibrous fabric sheet, which is opposite to the first
surface of the fibrous fabric sheet, which faces the adhesive
layer.
[0026] According to the above configuration, since the adhesive is
not exposed on the side of the fibrous fabric sheet, that may touch
the skin, when a user is wearing a jacket to which the slider
according to the embodiment of the present invention is applied,
the adhesive does not touch the skin of the neck or the like while
the slider touches the neck or the like. It is therefore possible
to maintain high cold feeling prevention effect without decreasing
soft feeling while strongly bonding the fibrous fabric sheet and
the slider body to each other.
[0027] According to the present invention, it is possible to
provide the slider for a slide fastener which rarely gives cold
feeling when the back surface of the slider for the slide fastener
touches the skin of the person, such as the neck, a shoulder, or
the chin in a case in which, for example, a jacket with the slide
fastener attached thereto is used for a long time in cold regions.
In addition, the slider has high durability and is fabricated at a
low cost.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0034] Hereinafter, embodiments of the present invention will be
described in detail with reference to FIG. 1 to FIG. 5.
[0035] FIG. 1 is an exploded perspective view schematically
illustrating a slider body and a fibrous fabric sheet of a slider
for a slide fastener according to the embodiment of the present
invention, FIG. 2 is a perspective view schematically illustrating
the state of the slider for the slide fastener according to the

present invention, for illustrating the back surface of the slider,
FIG. 4 is a cross-sectional view taken along line A-A in FIG. 3,
and FIG. 5 is a partially expanded cross-sectional view
schematically illustrating the state in which the fibrous fabric
sheet is fixed by adhesive penetrated into fibers of the fibrous
fabric sheet.
[0036] The upward direction in FIG. 3 refers to the forward
direction of the slider (slider body), the downward direction in
FIG. 3 refers to a rearward direction of the slider (slider body),
the left side in FIG. 3 refers to the left side of the slider
(slider body), and the right side in FIG. 3 refers to the right
side of the slider (slider body).
[0037] As shown in FIG. 1, the slider for a slide fastener
according to the embodiment of the present invention includes the
slider body 1 and a pull-tab (not shown). As shown in FIG. 1, FIG.
2 and FIG. 4, the slider body 1 includes an upper blade 2, a lower
blade 3 and a connecting post 7 which connects the front end
portions of the upper and lower blades 2 and 3 to each other. Right
and left upper and lower flanges 6 are respectively arranged on the
right and left side portions of the upper and lower blades 2 and 3.
In addition, an element guide path is formed between the upper and
lower blades 2 and 3 in the slider body 2.
[0038] Herein, a pull-tab attachment side of the slider body 1 is
referred to as the front side and a side opposite to the front side
of the slider body 1 is referred to as the back side unless
otherwise specified. In addition, the front surface of the slider
body 1 is a surface of the upper blade 2 at the front side (also
referred to as the front surface of the upper blade 2), and the
back surface of the slider body 1 is a surface of the lower blade 3
at the back side (also referred to as the back surface of the lower
blade 3).
[0039] As shown in FIG. 1, in the slider body 1, the fibrous fabric
sheet 10 is fixed to the back surface of the lower blade 3 by means
of an adhesive layer 8. The fibrous fabric sheet 10 can be made of
nonwoven fabric, woven fabric, fabric formed by knitting fibers, or
the like. The fibrous fabric sheet provided in this manner can
impart the function of preventing cold feeling to the slider.
[0040] In addition, the adhesive layer 8 may be formed by applying
a liquid adhesive or may be made of a sheet-shaped adhesive.
However, the sheet-shaped adhesive does not obstruct the function
of reducing cold feeling since a little amount of adhesive
components leaks and there is neither leakage from the
circumference of the fibrous fabric sheet 10 nor exuding from the
surface of the fibrous fabric sheet 10, as will be described later.
Although the adhesive is not specifically limited as long as it can
bond the fibrous fabric sheet 10 to the slider body 1, an
epoxy-based adhesive is preferably employed as the adhesive due to
its strong bonding force and durability since the slider according
to the embodiment of the present invention is often used in cold
regions. Although the sheet-shaped adhesive may one, both surfaces
of which are sticky, a multilayer structure in which several layers
of sheet-shaped adhesives are stacked one on another may be
employed.
[0041] When the fibrous fabric sheet 10 is attached to the slider
body 1, the fibrous fabric sheet 10 and the slider body 1 are
bonded together using an adhesive layer 8 interposed therebetween
such that one surface of the fibrous fabric sheet 10 faces the back
surface of the lower blade of the slider body. Referring to the
slider to which the fibrous fabric sheet 10 is bonded to the back
surface of the slider, as shown in FIG. 2 and FIG. 3, a
circumferential portion 11 on the back surface of the lower blade 3
is exposed without being covered with the fibrous fabric sheet 10.
That is, the fibrous fabric sheet 10 is not present on the
circumferential portion 11. In addition, the fibrous fabric sheet
10 is arranged such that the fibrous fabric sheet 10 does not
protrude toward the outside of the slider body beyond the adhesive
layer 8. In this case, since there is little possibility that the
fibrous fabric sheet 10 be subjected to peeling force of stripping
off the fibrous fabric sheet 10 from slider body 10, the fibrous
fabric sheet 10 can be strongly bonded to the slider body 1,
thereby ensuring the durability of the slider with the function of
reducing cold feeling.
[0042] In addition, as shown in FIG. 4, the back surface of the
lower blade 3 includes a chamfered portion 12 at the
circumferential portion 11 thereof, the chamfered portion 12 being
curved so as to come close to the upper blade 2 toward the outside
of the slider body 1, and a flat surface 13 surrounded by the
chamfered portion 12. The fibrous fabric sheet 10 is fixed to the
flat surface 13. According to this configuration, the fibrous
fabric sheet 10 can be configured so as not be present on the
circumferential portion 11 since the fibrous fabric sheet 10 is
arranged on the flat surface 13 surrounded by the chamfered portion
12.
[0043] In the meantime, all the portions surrounded by the
chamfered portion 12 are not required to be formed as the flat
surface. In the portions surrounded by the chamfered portion 12, at
least a portion adjacent to the chamfered portion 12 is preferably
formed as the flat surface. For example, concaves and convexes may
be formed on the central portion of the back surface of the lower
blade 3.
[0044] In the embodiment shown in FIG. 5, the fibrous fabric sheet
10 is bonded to the flat surface 13 at a certain distance from the
boundary of the flat surface 13. This configuration can further
prevent the fibrous fabric sheet 10 from being subjected to the
peeling force with which the fibrous fabric sheet 10 is stripped
off from the slide body 1.
[0045] In addition, since the chamfered portion 12 is formed on the
circumferential portion 11, a corner of the lower blade does not
easily touch the neck or the like. It is possible to prevent cold
feeling that would otherwise be caused when the metal slider
touches the skin.
[0046] Furthermore, in order to ensure that the fibrous fabric
sheet 10 is strongly fixed by the adhesive, as shown in FIG. 5, the
bonding structure is configured such that the adhesive penetrates
between the fibers of the fibrous fabric sheet 10 from a first
surface of the fibrous fabric sheet 10, which faces the adhesive
layer 8, thereby fixing the fibrous fabric sheet 10. With this
bonding structure, since some of the fibers exposed on the first
surface of the fibrous fabric sheet 10, which faces the adhesive
layer 8 are buried in the adhesive, it is possible to strongly bond
the fibrous fabric sheet 10 and the slider body 1 to each
other.
[0047] In addition, although the adhesive penetrates between the
fibers of the fibrous fabric sheet 10, the adhesive does not exude
from a second surface of the fibrous fabric sheet 10, which is
opposite to the first surface of the fibrous fabric sheet 10, which
faces the adhesive layer 8 in order not to have an adverse effect
on the feeling of the skin.
[0048] In order to effectively prevent the fibrous fabric sheet 10
from exuding from the second surface, which is opposite to the
first surface, the adhesive is preferably implemented as a
sheet-shaped adhesive. Since the sheet-shaped adhesive has
significantly smaller liquidity and higher viscosity than the
liquid adhesive, the sheet-shaped adhesive rarely leaks from the
circumference of the fibrous fabric sheet 10 or exudes from the
second surface of the fibrous fabric sheet 10, which is opposite to
the first surface.
[0049] As described above, the embodiment of the present invention
is configured as follows.
[0050] The slider for a slide fastener according to the embodiment
of the present invention comprises the slider body 1 which includes
the upper blade 2 disposed on the front side of the slider body 1,
which is the pull-tab attachment side, the lower blade 3 disposed
on the back side of the slider body 1, which is opposite to the
front side, and the connecting post 7 connecting the upper blade 2
and the lower blade 3 to each other. The fibrous fabric sheet 10 is
integrally fixed to the back surface of the lower blade 3 at the
back side, with the adhesive layer 8 being interposed between the
fibrous fabric sheet 10 and the lower blade 3.
[0051] According to this configuration, it is possible to impart
the function of preventing cold feeling to existing sliders at a
low cost without adapting the slider body 1 to a special shape.
[0052] In addition, since a member for preventing cold feeling is
the fibrous fabric sheet 10, the member does not become cold even
after the elapse of a long time. Therefore, when the member
partially touches the skin of the neck or the like, the member
rarely gives cold feeling.
[0053] Furthermore, since the fibrous fabric sheet 10 is a
sheet-shaped article, the fibrous fabric sheet 10 is not easily
released from the slider body 1, thereby obtaining high
durability.
[0054] According to the embodiment of the present invention as
described above, the circumferential portion 11 of the back surface
of the lower blade 3 is preferably exposed without being covered
with the fibrous fabric sheet 10.
[0055] According to this configuration, since the fibrous fabric
sheet 10 is not present at least on the circumference of the back
surface of the slider body 1, it is possible to reduce the
possibility that the fibrous fabric sheet 10 may be stripped off
from the end portion thereof, thereby improving the durability of
the slider with the function of preventing cold feeling.
[0056] According to the embodiment of the present invention, the
back surface of the lower blade 3 preferably has the chamfered
portion 12 at the circumferential portion 11 thereof, the chamfered
portion 12 being curved or inclined so as to come close to the
upper blade 2 toward the outside of the slider body 1, and the flat
surface 13 surrounded by the chamfered portion 12. The fibrous
fabric sheet 10 is preferably fixed to the flat surface 13.
[0057] According to this configuration, since the circumferential
edge portion of the fibrous fabric sheet 10 does not extend outward
beyond the circumference of the back surface of the lower blade 3,
it is possible to reduce the possibility that the fibrous fabric
sheet 10 may be stripped off from the end portion thereof, thereby
improving the durability of the slider with the function of
preventing cold feeling.
[0058] In addition, since the circumferential portion 11 of the
back surface of the lower blade 3 is chamfered such that the
circumferential portion 11 is curved or inclined toward the upper
blade, the circumferential portion 11 of the lower blade 3 rarely
touches the neck or the like. This consequently lowers the
possibility that the circumferential portion 11 may touch the skin
and give cold feeling to the skin.
[0059] According to the embodiment of the present invention as
described above, preferably, the fibrous fabric sheet 10 does not
protrude toward the outside of the slider body 1 beyond the
adhesive layer 8.
[0060] This configuration can prevent the fibrous fabric sheet 10
from being stripped off from the end portion while strongly bonding
the fibrous fabric sheet 10 to the slider body 1.
[0061] According to the embodiment of the present invention as
described above, the adhesive layer 8 is preferably formed of an
adhesive or an adhesive sheet, and the adhesive is an epoxy-based
adhesive.
[0062] According to this configuration, since the epoxy-based
adhesive has strong bonding force and can withstand low
temperature, the fibrous fabric sheet 10 and the slider body 1 can
be strongly bonded to each other.
[0063] According to the embodiment of the present invention as
described above, the adhesive preferably fixes the fibrous fabric
sheet 10 through penetration between the fibers of the fibrous
fabric sheet 10 from the first surface of the fibrous fabric sheet
10, which faces the adhesive layer 8.
[0064] According to this configuration, since some of the fibers
exposed on the first surface of the fibrous fabric sheet 10 that
faces the adhesive layer 8 are buried in the adhesive, the fibrous
fabric sheet 10 and the slider body 1 can be strongly bonded to
each other.
[0065] According to the embodiment of the present invention as
described above, preferably, the adhesive does not exude from the
second surface of the fibrous fabric sheet 10, which is opposite to
the first surface of the fibrous fabric sheet 10, that faces the
adhesive layer 8.
[0066] According to this configuration, since the adhesive is not
exposed on the side of the fibrous fabric sheet 10, that may touch
the skin, when a user is wearing a jacket to which the slider
according to the embodiment of the present invention is applied,
the adhesive does not touch the skin of the neck or the like while
the slider touches the neck or the like. It is therefore possible
to maintain high cold feeling prevention effect without decreasing
soft feeling while strongly bonding the fibrous fabric sheet 10 and
the slider body 1 to each other.
[0067] Although the present invention has been described in
relation to one exemplary embodiment, a variety of changes can be
made without departing from the concept of the present
invention.
[0068] For instance, although the present invention was illustrated
as being applied to the metal slider by way of example, the present
invention can be applied to a resin slider.
