Technical Field
[0001] The present invention relates to a slide fastener and a method for manufacturing
an end stop of the slide fastener, and more particularly, to a top end stop and a
bottom end stop for a slide fastener and a manufacturing method thereof.
Background Art
[0002] Slide fasteners usually employ a configuration in which an end stop made of synthetic
resin, such as a top end stop or a bottom end stop, is installed on an end portion
of a fastener element row to stop sliding of a slider and thus prevent the slider
from being released from the fastener element row. Lower ends of the opposing fastener
element rows are connected to each other by the bottom end stop to prevent the slider
from being released.
[0003] There is known a conventional slide fastener including a bottom end stop having a
back plate provided with a through-hole, and a rivet member fixed to the back plate
by engaging and deforming a protruding pin with the through-hole (e.g., see Patent
Document 1).

Advantageous Effects of Invention
[0009] According to the slide fastener of the present invention, since the slide fastener
includes the end stops disposed at the upper and lower end portions of the pair of
fastener element rows to stop sliding movement of the slider and the decoration member
mounted on at least one of the end stops, the decoration member which is arbitrarily
decorated is mounted on the end stop, thereby giving the decorativeness to the end
stop.
[0010] At least one of the end stop includes the tape accommodation portion for accommodating
the fastener tape and the engaged portion for engaging the decoration member therewith,
and the decoration member includes the body portion which is decorated and the engaging
portion provided on the back surface of the body portion and configured to be engaged
with the engaged portion. Therefore, as the engaging portion is engaged with the engaged
portion, the decoration member can be easily attached to the end stop. Further, since
the engaging portion is engaged with the engaged portion, it is possible to reliably
prevent the decoration member from being released from the end stop.
[0011] Further, according to the slide fastener of the present invention, the back surface
side of the engaging portion is provided with the extension portion protruding in
the front and back direction of the fastener tape, and after the engaging portion
is inserted into the engaged portion together with the extension portion, the extension
portion is pulled in the direction toward the back surface of the end stop to engage
the engaging portion with the engaged portion. Therefore, it is possible to easily
engage the engaging portion with the engaged portion, without using a tool.
[0012] In addition, the extension portion has the weakened portion of which the mechanical
strength is set to be weaker than that of the other portions, and the extension portion
can be separated and removed from the engaging portion on the basis of the weakened
portion as a breakage starting point. Therefore, after the decoration member is mounted
onto the end stop, the extension portion is separated and removed from the engaging
portion to maintain the good decorativeness.

Embodiments of Invention
[0014] One embodiment of a slide fastener according to the present invention will now be
described in detail with reference to the accompanying drawings. In the following
description, a front side refers to a near side with respect to the paper surface
of FIG. 1, a back side refers to a far side with respect to the paper surface of FIG.
1, an upper side refers to an upper side with respect to the paper surface of FIG.
1 (i.e., a side of a direction in which the slider slides to engage fastener element
rows 30 of the slide fastener, as will be described later), a lower side refers to
a lower side with respect to the paper surface of FIG. 1 (i.e., a side of a direction
in which the slider slides to disengage the fastener element rows 30, as will be described
later), a left side refers to a left side with respect to the paper surface of FIG.
1, and a right side refers to a right side with respect to the paper surface of FIG.
1. Further, a right and left direction of a fastener tape is also referred to as a
width direction. Also, the upward and downward direction of the fastener tape refers
to a longitudinal direction.
[0015] A slide fastener 10 of this embodiment includes, as illustrated in FIG. 1, a pair
of right and left fastener tapes 20, a pair of right and left fastener element rows
30 respectively provided on opposing tape-side edge portions 20a of the pair of right
and left fastener tapes 20 in a longitudinal direction and having a plurality of fastener
elements 31, a slider (not illustrated) configured to engage and disengage the right
and left fastener element rows 30, bottom end stops 50 provided at lower end portions
of the right and left fastener element rows 30 and 30 and attached adjacent to the
fastener elements 31, top end stops (not illustrated) each provided on upper end portions
of the right and left fastener element rows 30, and a decoration member 60 mounted
on the bottom end stop 50. As the slider is moved in an upward and downward direction,
the pair of right and left fastener element rows 30 are engaged and disengaged. The
downward sliding movement of the slide is restricted by the bottom end stops 50, while
the upward sliding movement of the slide is restricted by the top end stops, thereby
preventing the slider from being released from the fastener element rows 30.
[0016] Each of the pair of right and left fastener element rows 30 is comprised of a plurality
of fastener elements 31, and the fastener elements are formed on the tape-side edge
portion 20a of the fastener tape 20 by injection molding using synthetic resin, for
example, polyamide, polyacetal, polypropylene, or polybutylene terephthalate.
[0017] The bottom end stop 50 has, as illustrated in FIGs. 1 to 5, a pair of right and left
tape accommodation portions 51 which are formed by injection molding while straddling
the pair of right and left fastener tapes 20 to respectively accommodate the fastener
tape 20 and is formed in a rectangular shape along a sliding direction of the slider,
two through-holes (engaging portions) engaging with the decoration member 60, a wall
portion 53 erected from the whole circumference of the front-side edge portion of
the bottom end stop 50, and an accommodation recess portion 54 formed in the wall
portion 53 to accommodate the decoration member 60. The through-hole 52 is formed
in the front and back direction of the fastener tape 20. The through-hole 52 is formed
between the pair of right and left fastener tapes 20 at a center portion in the width
direction of the fastener tape 20.
[0018] Two through-holes 52 are formed at the center portion of the width direction of the
bottom end stop 50 along the longitudinal direction of the bottom end stop 50. Further,
the through-hole 52 is formed in the rectangular shape along the longitudinal direction
of the bottom end stop 50. An inner peripheral surface of the through-hole 52 is covered
by synthetic resin. In other words, a synthetic resin layer exists between the inner
peripheral surface of the through-hole 52 and the fastener tape 20, so that the fastener
tape 20 is not exposed inwardly from the through-hole 52.
[0019] The decoration member 60 has, as illustrated in FIGs. 1 to 3, 6 and 7, a plate member
(body portion) 61 with a front surface which is decorated, and two engaging leg portions
(engaging portion) 62 which projectingly provided on a back surface of the plate member
61 and are respectively engaged with the through-holes 52 of the bottom end stop 50.
[0020] The plate member 61 is a plate-like member having a size to be fitted into an inside
of the accommodation recess portion 54 of the bottom end stop 50. A front surface
61a of the plate member 61 is decorated with an arbitrary decoration such as a logo
mark, characters, a pattern, various marks, or color.
[0021] The engaging leg portion 62 is a substantially T-shape projection which can be fitted
into the through-hole 52 of the bottom end stop 50, and is formed in a rectangular
shape along the longitudinal direction of the fastener tape 20. Further, the engaging
leg portion 62 is formed so that its side in the longitudinal direction is to be longer
than its side in the width direction.
[0022] As illustrated in FIGs. 2 to 5, a lateral surface of the long side which is the inner
peripheral surface of the through-hole 52 of the bottom end stop 50 is formed as an
inclined surface 55 of which a dimension in the width direction is gradually decreased
from the front surface side of the bottom end stop 50 toward the back surface side
thereof. Similarly, the lateral surface of the short side is formed as an inclined
surface 56 of which a dimension in the longitudinal direction is gradually decreased
from the front surface side of the bottom end stop 50 toward the back surface side
thereof. The inclined surface 56 of the short side of the through-hole 52 is provided
at the back side thereof with an engaging stepped portion 57 of a trapezoidal shape,
which is engaged with the engaging portion 63 of the engaging leg portion 62. Further,
the back surface side of the through-hole 52 is formed with a leg portion receiving
recess portion 58 which is formed continuous with the inclined surface 55 of the long
side and the engaging stepped portion 57 to receive the engaging leg portion 62 of
the decoration member 60.
[0023] The decoration member 60 is shaped by a soft synthetic resin material, and the bottom
end stop 50 is shaped by a synthetic resin material harder than the decoration member
60. For this reason, the decoration member 60 is soft as compared with the bottom
end stop 50, so that it can be elastically deformed in a relatively easy way. Accordingly,
the engaging leg portion 62 of the decoration member 60 can be easily inserted into
the through-hole 52 of the bottom end stop 50. In this instance, the soft synthetic
material includes, for example, polyurethane, silicon rubber, and thermoplastic elastomer.
[0024] As described above, according to the slide fastener 10 of this embodiment, since
the decoration member 60 which is arbitrarily decorated is mounted on the bottom end
stop 50, decorativeness can be given to the bottom end stop 50, and, consequently,
various decorations can be given to the slide fastener 10.
[0025] Since the bottom end stop 50 has the tape accommodation portion 51 for accommodating
the fastener tape 20 and the through-hole 52 engaged with the decoration member 60,
and the decoration member 60 has the plate member 61 which is arbitrarily decorated,
and the engaging leg portions 62 which projectingly provided on the back surface of
the plate member 61 to respectively engage with the through-holes 52, the decoration
member 60 can be easily attached to the bottom end stop 50. Further, since the through-hole
52 and the engaging leg portion 62 are engaged, it is possible to reliably prevent
the decoration member 60 from being released from the bottom end stop 50.
[0026] According to the slide fastener 10 of this embodiment, since the through-hole 52
has the engaging stepped portion 57 engaging with the engaging leg portion 62 of the
decoration member 60, it is possible to reliably prevent the decoration member 60
from being released from the bottom end stop 50. Further, since the engaging leg portion
62 is received in the leg portion receiving recess portion 58 of the through-hole
52, the engaging leg portion 62 is not exposed from the back surface of the bottom
end stop 50, thereby enhancing the decorativeness of the slide fastener 10.
[0027] According to the slide fastener 10 of this embodiment, since the engaging leg portion
62 is formed along the longitudinal direction of the fastener tape 20, the engaging
leg portion 62 can be easily inserted into the through-hole 52 of the bottom end stop
50, thereby easily carrying out the operation of mounting the decoration member 60
onto the bottom end stop 50.
[0028] Further, according to the slide fastener 10 of this embodiment, since the decoration
member 60 is made of the synthetic resin material and the bottom end stop 50 is made
of the synthetic resin material harder than the decoration member 60, the engaging
leg portion62 of the soft decoration member 60 can be flexibly deformed to be inserted
into the through-hole 52 of the hard bottom end stop 50. Accordingly, the decoration
member 60 can be easily attached to the bottom end stop 50.
[0029] Since the inner peripheral surface of the through-hole 52 of the bottom end stop
50 is covered by the synthetic resin, the fastener tape 20 is not exposed from the
inside of the through-hole 52. Accordingly, since the engaging leg portion 62 of the
decoration member 60 is not in contact with the fastener tape 20, the engaging leg
portion 62 can be smoothly inserted and engaged with the through-hole 52.
[0030] According to the slide fastener 10 of this embodiment, since the plate member 61
of the decoration member 60 is accommodated in the accommodation recess portion 54
which is the inside of the portion enclosed by the wall portion 53 of the bottom end
stop 50, it is possible to prevent the plate member 61 from being in contact with
external members, thereby preventing the decoration member 60 from being released
from the bottom end stop 50.
[0031] According to the slide fastener 10 of this embodiment, since the bottom end stop
50 is formed in the rectangular shape along the sliding direction of the slider, the
bottom end stop 50 can be firmly attached to the fastener tape 20.
[0032] Further, since the through-hole 52 is formed in the rectangular shape along the longitudinal
direction of the bottom end stop 50, and two through-holes are disposed along the
longitudinal direction of the bottom end stop 50, attachment strength of the bottom
end stop 50 and the decoration member 60 can be improved, thereby preventing the decoration
member 60 from being released from the bottom end stop 50.
[0033] According to the slide fastener 10 of this embodiment, since the inner peripheral
surface of the through-hole 52 of the bottom end stop is provided with the inclined
surfaces 55 and 56 at the insertion hole side, the engaging leg portion 62 of the
decoration member 60 is guided to the through-hole 52, the engaging leg portion 62
can be easily inserted into the through-hole 52, thereby easily carrying out the operation
of mounting the decoration member 60 onto the bottom end stop 50.
(Modification 1)
[0034] As the first modification of this embodiment, the bottom end stop 50 may be substituted
with a bottom end stop 50A in Fig. 8. In the bottom end stop 50A, the engaging stepped
portion 57 and the leg portion receiving recess portion 58 are eliminated from the
through-hole 52, and the engaging leg portion 62 of the decoration member 60 is engaged
with the back surface of the bottom end stop 50A. In addition, the wall portion 53
is eliminated.
(Modification 2)
[0035] As the second modification of this embodiment, the bottom end stop 50 and the decoration
member 60 may be substituted with a bottom end stop 50B and a decoration member 60B
in Fig. 9. The bottom end stop 50B is formed in the rectangular shape of which a length
is long in the width direction, and is provided on the front surface thereof with
a star-type wall portion 53B. Further, the decoration member 60B is formed in a star-type
which can be fitted into the wall portion 53B. In this modification, one through-hole
and one engaging leg portion which are not illustrated are provided at the center
portions of the bottom end stop 50B and the decoration member 60B.
(Modification 3)
[0036] As the third modification of this embodiment, the bottom end stop 50 and the decoration
member 60 may be substituted with a bottom end stop 50C and a decoration member 60C
in FIG. 10. The bottom end stop 50C is formed in a circular shape, and the front surface
thereof is provided with a circular wall portion 53C. Further, the decoration member
60C is formed in a circular shape which can be fitted into the wall portion 53C. In
this embodiment, one through-hole and one engaging leg portion which are not illustrated
are provided at the center portions of the bottom end stop 50C and the decoration
member 60C. The through-hole and the engaging leg portion may not be formed in the
rectangular shape, but be formed in a circular shape.
(Modification 4)
[0037] As the fourth modification of this embodiment, the bottom end stop 50 and the decoration
member 60 may be substituted with a bottom end stop 50D and a decoration member 60D
in FIG. 11. A front surface of the bottom end stop 50D is provided with an engaging
groove portion (engaged portion) 52D having an inverted T-shape in cross section along
the longitudinal direction, and a bottom surface of the plate member 61D of the decoration
member 60D is provided with an engaging projection (engaging portion) 62D having an
inverted T-shape in cross section, which is fitted into the engaging groove 52D, along
the longitudinal direction. In this embodiment, as the engaging projection 62D of
the decoration member 60D is slidingly fitted into the engaging groove 52D of the
bottom end stop 50D, the decoration member 60D is mounted onto the bottom end stop
50D.
(Modification 5)
[0038] As the fifth modification of this embodiment, as illustrated in FIG. 12, the plate
member 61D may be eliminated from the decoration member 60D of the fourth modification,
a convex portion on the upper portion of the engaging projection 62D may be a body
portion 61E, and an upper surface of the body portion 61E may be decorated (in this
embodiment, with symbols "1" and "2").
(Modification 6)
[0039] As the sixth modification of this embodiment, as illustrated in FIGs. 13 and 14,
a decoration member 60F formed with an extension portion 65 which protrudes in the
front and back direction of the fastener tape 20 may be provided on the back surface
side of the engaging leg portion 62 of the decoration member 60 illustrated in FIGs.
6 and 7. The length of the extension portion 65 is preferably at least a length of
the front end portion protruding from the back surface of the bottom end stop 50 in
order to easily hold the extension portion 65 when the extension portion 65 is inserted
into the through-hole 52 of the bottom end stop 50.
[0040] Further, both sides of the extension portion 65 is provided with a pair of substantially
V-shape grooves 66 along the longitudinal direction at a substantially center portion
of the width direction. That is, a junction area of a junction portion between the
extension portion 65 and the engaging leg portion 62 is set so that a substantially
center portion of the extension portion 65 in the width direction is smaller than
that of other portion, which configures a weakened portion 67 of low mechanical strength.
In this instance, the groove 66 is configured to form the weakened portion 67 at the
junction portion between the extension portion 65 and the engaging leg portion 62.
The groove 66 is formed at the junction portion between the extension portion 65 and
the engaging leg portion62, and it is not necessary to form the groove 66 over the
overall length of the extension portion 65. Further, if the extension portion 65 is
not necessarily separated from the engaging leg portion 62, the groove 66 (weakened
portion 67) may not be formed.
[0041] When assembling the decoration member 60F, as illustrated in FIG. 15A, the extension
portion 65 of the decoration member 60F is inserted into the through-hole 52 of the
bottom end stop 50, and the extension portion 65 protruding from the through-hole
52 toward the back surface side is held and pulled up in the drawing. Accordingly,
as illustrated in FIG. 15B, the engaging portion 63 of the decoration member 60F made
of the synthetic resin material softer than the bottom end stop 50 is elastically
deformed, and then is inserted into the through-hole 52 of the bottom end stop 50,
thereby being engaged with the through-hole 52 of the bottom end stop 50. In this
instance, tensile strength of the weakened portion 67 is set to be higher than the
strength required for elastically deforming the engaging portion 63 when being engaged
with the through-hole 52.
[0042] As illustrated in FIG. 15C, if a force higher than breaking strength is applied to
the weakened portion 67, for example, the extension portion 65 is strongly pulled
up at an angle, the extension portion 65 is broken at a root portion on the basis
of the weakened portion 67 as a breakage starting point, and then is separated from
the engaging leg portion 62, while an extension portion removal trace 62a is left
on the engaging leg portion 62.
[0043] The extension portion removal trace 62a left on the engaging leg portion 62 does
not cause a trouble to its function as it is, but may be subjected to surface finishing
to smoothen the surface. In this instance, the extension portion removal trace 62a
is a portion of which an appearance is different from other surface formed when the
decoration member 60F is formed, and includes a surface which is subjected to the
surface smoothening process after the extension portion 65 is removed. In addition,
the appearance mentioned herein refers to a portion which it is can be judged to be
different from other portions in view of sense of sight or touch including gloss,
surface roughness, surface shape and so forth.
[0044] The extension portion 65 can be broken and removed from the weakened portion 67 by
strongly pulling it. However, if the extension portion is cut by a cutter, the extension
portion 65 can be removed in a clean state as compared with the extension portion
removal trace 62a. In this instance, the weakened portion 67 is not limited to its
shape or configuration if the mechanical strength at the junction portion between
the extension portion 65 and the engaging leg portion 62 is weaker than that of other
portions.
[0045] According to this modification, the back surface side of the engaging leg portion
62 is provided with the extension portion 65 protruding in the front and back direction
of the fastener tape 20, and after the engaging leg portion 62 is inserted into the
through-hole 52 together with the extension portion 65, the extension portion 65 is
pulled in the direction toward the back surface of the bottom end stop 50 to engage
the engaging portion 63 with the through-hole 52. As a result, it is possible to easily
engage the engaging portion 63 with the through-hole 52 without using a tool, thereby
improving the workability. Therefore, for example, an arbitrary decoration member
60F selected by a customer can be attached on the spot, which can cope with the demand
of the customer quickly.
[0046] In addition, the extension portion 65 has the weakened portion 67 of which the mechanical
strength is set to be weaker than that of other portion, and the extension portion
65 can be separated and removed from the engaging leg portion 62 on the basis of the
weakened portion 67 as the breakage starting point. Therefore, after the decoration
member 60F is mounted onto the bottom end stop 50, the extension portion 65 is separated
and removed from the engaging leg portion 62 to maintain the good decorativeness.
(Modification 7)
[0047] As the seventh modification of this embodiment, the extension portion 65 may be substituted
with an extension portion 65G in FIG. 16. The extension portion 65G has a rectangular
shape in cross section, and a substantially V-shape cutaway portion 68 is formed at
the junction portion of the engaging leg portion 62 as the weakened portion 67.
(Modification 8)
[0048] As the eighth modification of this embodiment, the extension portion 65 may be substituted
with an extension portion 65H in FIG. 17. The extension portion 65H has a rectangular
shape in cross section, and the junction portion of the engaging leg portion 62 is
provided with a plurality of holes 69 as the weakened portion 67.
(Modification 9)
[0049] As the ninth modification of this embodiment, the extension portion 65 may be substituted
with an extension portion 65K in FIG. 18. The extension portion 65K has a substantially
triangular shape in cross section in which a width of one end side of the engaging
leg portion 62 in the longitudinal direction is gradually decreased from a width of
the other end side, and an apex of which a junction area with the engaging leg portion
62 is small functions as the weakened portion 67. That is, an orientation is imparted
to the junction strength between the extension portion 65K and the engaging leg portion
62. Accordingly, when the extension portion 65K is broken, the extension portion 65K
is bent and pulled to be inclined toward the triangular bottom side, so that the force
is concentrated on the weakened portion 67 to break the weakened portion.
[0050] In addition, as illustrated in FIGs. 19 to 22, the decoration member 60 may be mounted
onto the top end stop 70 which is provided on the upper end portion of the fastener
element row 30. The top end stop 70 is formed in a square shape, and the plate member
61 of the decoration member 60 is formed in a square shape smaller than the top end
stop 70. Further, the top end stop 70 has the same construction as the bottom end
stop 50, and the engaging stepped portion 57 and the leg portion receiving recess
portion 58 are eliminated from the through-hole 52. The engaging leg portion 62 of
the decoration member 60 is engaged with the back surface of the top end stop 70,
and the wall portion 53 is removed. One through-hole 52 and one engaging leg portion
62 are provided at the center portion of the decoration member 60 and the top end
stop 70. In addition, the lower edge portion of the top end stop 70 is provided with
a projection 71 near the fastener tape 20, and the projection 71 protrudes toward
the fastener element row 30, and is inserted in the slider (not illustrated).
(Usage Example)
[0051] The slide fastener 10 of this embodiment can be used at an opening 81 of a bag 80,
as illustrated in FIG. 23, and can be used at a chest pocket 91 of a jacket 90, as
illustrated in Fig. 24.
[0052] The present invention is not limited to the above-described embodiment, and can be
properly modified or revised without being deviated from the gist of the invention.
For example, in the above embodiment, the decoration member is attached to the stop
by engaging the through-hole and the engaging leg portion, but the present invention
is not limited thereto. The decoration member may be attached to the stop by adhesion.
Further, the engaging portion may have a substantially J-shape or substantially T-shape.
The recess portion may be a groove or a hole.
