Patent Application No. 109100938, filed on Jan. 10, 2020. The
entire content of the above identified application is incorporated
herein by reference.
[0002] Some references, which may include patents, patent
applications and various publications, may be cited and discussed
in the description of this disclosure. The citation and/or
discussion of such references is provided merely to clarify the
description of the present disclosure and is not an admission that
any such reference is "prior art" to the disclosure described
herein. All references cited and discussed in this specification
are incorporated herein by reference in their entireties and to the
same extent as if each reference was individually incorporated by

FIELD OF THE DISCLOSURE
[0003] The present disclosure relates to an assembly structure and
an element thereof, and more particularly to a zipper head assembly
structure and a sliding element thereof.
BACKGROUND OF THE DISCLOSURE
[0004] Basic fastening components of common items of clothing are
rarely anything other than buttons or zippers. Compared to buttons,
the zipper structure has better usability and stronger structural
characteristics. A common zipper structure includes a zipper head
and a zipper tape that serve cooperatively as a guiding part for
pulling and reciprocating movement of the zipper structure, so that
the zipper structure has become more popular in clothing and
accessories. However, zipper heads in the related art still have
room for improvement.
SUMMARY OF THE DISCLOSURE
[0005] In response to the above-referenced technical inadequacies,
the present disclosure provides a zipper head assembly structure
and a sliding element thereof.
[0006] In one aspect, the present disclosure provides a zipper head
assembly structure, including a sliding element, an elastic element
and a pulling element. The sliding element includes a first sliding
portion, a second sliding portion corresponding to the first
sliding portion, a connection portion connected between the first
sliding portion and the second sliding portion, two riveted
portions disposed on the first sliding portion, and two stop
portions respectively adjacent to the two riveted portions. The
elastic element is disposed on the sliding element. The elastic
element includes a retaining portion retained by the connection
portion, a movable portion movably passing through the first
sliding portion, and an elastic portion connected between the
retaining portion and the movable portion. The pulling element
includes a pivot portion movably disposed on the first sliding
portion and two abutting portions respectively connected to two
opposite sides of the pivot portion. The pivot portion includes two
pivot sections respectively pivotally mated with the two riveted
portions, and an abutting section connected between the two pivot
sections. When the pulling element has not been moved relative to
the sliding element yet and is substantially horizontally placed on
the first sliding portion, the elastic portion of the elastic
element downwardly abuts against the abutting section of the pivot
portion of the pulling element. When the pulling element has been
moved relative to the sliding element so as to make the pulling
element substantially perpendicular to the first sliding portion,
the abutting section of the pivot portion of the pulling element
upwardly abuts against the elastic portion of the elastic element,
and the two abutting portions of the pulling element respectively
abut against the two stop portions, so that the pulling element is
blocked by the two stop portions.
[0007] In another aspect, the present disclosure provides a zipper
head assembly structure, including a sliding element, an elastic
element and a pulling element. The sliding element includes a first
sliding portion, two riveted portions disposed on the first sliding
portion, and two stop portions respectively adjacent to the two
riveted portions. The elastic element is disposed on the sliding
element. The pulling element includes a pivot portion movably
disposed on the first sliding portion and two abutting portions
respectively connected to two opposite sides of the pivot portion.
When the pulling element has been moved relative to the sliding
element so as to make the pulling element substantially
perpendicular to the first sliding portion, the two abutting
portions of the pulling element respectively abut against the two
stop portions, so that the pulling element is blocked by the two
stop portions.
[0008] In yet another aspect, the present disclosure provides a
sliding element, including a first sliding portion, a second
sliding portion corresponding to the first sliding portion, a
connection portion connected between the first sliding portion and
the second sliding portion, two riveted portions disposed on the
first sliding portion, and two stop portions respectively adjacent
to the two riveted portions. When a pulling element has been moved
relative to the sliding element so as to make the pulling element
substantially perpendicular to the first sliding portion, the two
abutting portions of the pulling element respectively abut against
the two stop portions, so that the pulling element is blocked by
the two stop portions.
[0009] Therefore, by virtue of "the sliding element including a
first sliding portion, two riveted portions disposed on the first
sliding portion, and two stop portions respectively adjacent to the
two riveted portions" and "the pulling element including a pivot
portion movably disposed on the first sliding portion and two
abutting portions respectively connected to two opposite sides of
the pivot portion", when the pulling element has been moved
relative to the sliding element so as to make the pulling element
substantially perpendicular to the first sliding portion, the two
abutting portions of the pulling element respectively abut against
the two stop portions, so that the pulling element is blocked by
the two stop portions.
[0010] Furthermore, by virtue of "the two riveted portions being
disposed on the first sliding portion" and "the two stop portions
being respectively adjacent to the two riveted portions", when the
pulling element has been moved relative to the sliding element so
as to make the pulling element substantially perpendicular to the
first sliding portion, the two abutting portions of the pulling
element respectively abut against the two stop portions, so that
the pulling element is blocked by the two stop portions.
[0011] These and other aspects of the present disclosure will
become apparent from the following description of the embodiment
taken in conjunction with the following drawings and their
captions, although variations and modifications therein may be
affected without departing from the spirit and scope of the novel
concepts of the disclosure.

First Embodiment
[0026] Referring to FIG. 1 to FIG. 10, a first embodiment of the
present disclosure provides a zipper head assembly structure Z,
including a sliding element 1, an elastic element 2 and a pulling
element 3.
[0027] Firstly, referring to FIG. 1 to FIG. 5, the sliding element
1 (or a zipper head) includes a first sliding portion 11, a second
sliding portion 12 corresponding to the first sliding portion 11, a
connection portion 13 connected between the first sliding portion
11 and the second sliding portion 12, two riveted portions 14
disposed on the first sliding portion 11, and two stop portions 15
respectively adjacent to the two riveted portions 14. For example,
the first sliding portion 11 has a first end portion 111 suspended
therefrom and a second end portion 112 opposite to the first end
portion 111 of the first sliding portion 11, and the second sliding
portion 12 has a first end portion 121 suspended therefrom and a
second end portion 122 opposite to the first end portion 121 of the
second sliding portion 12. In addition, the first end portion 111
of the first sliding portion 11 corresponds to the first end
portion 121 of the second sliding portion 12, and the connection
portion 13 is connected between the second end portion 112 of the
first sliding portion 11 and the second end portion 122 of the
second sliding portion 12. However, the aforementioned description
for the sliding element 1 is merely an example and is not meant to
limit the scope of the present disclosure.
[0028] Moreover, referring to FIG. 1 to FIG. 5, the elastic element
2 is disposed on the sliding element 1, and the elastic element 2
includes a retaining portion 21 retained by the connection portion
13, a movable portion 22 movably passing through the first sliding
portion 11, and an elastic portion 23 connected between the
retaining portion 21 and the movable portion 22. For example, the
first sliding portion 11 has a through opening 110, the movable
portion 22 of the elastic element 2 movably passes through the
through opening 110 of the first sliding portion 11, and the two
riveted portions 14 are respectively disposed beside two opposite
sides of the through opening 110. However, the aforementioned
description for the elastic element 2 is merely an example and is
not meant to limit the scope of the present disclosure.
[0029] Furthermore, referring to FIG. 1 to FIG. 5, the pulling
element 3 includes a pivot portion 31 movably disposed on the first
sliding portion 11 and two abutting portions 32 respectively
connected to two opposite sides of the pivot portion 31, and the
pivot portion 31 includes two pivot sections 311 respectively
pivotally mated with the two riveted portions 14, and an abutting
section 312 connected between the two pivot sections 311. For
example, the abutting section 312 has a concave region 3121 formed
between the two pivot sections 311 and an abutting region 3122
outwardly extended from the concave region 3121. However, the
aforementioned description for the pulling element 3 is merely an
example and is not meant to limit the scope of the present
disclosure.
[0030] More particularly, referring to FIG. 1, FIG. 3 and FIG. 6 to
FIG. 8, when the pulling element 3 has not been moved relative to
the sliding element 1 yet and is substantially horizontally placed
on the first sliding portion 1, the elastic portion 23 of the
elastic element 2 can downwardly abut against the abutting section
312 of the pivot portion 31 of the pulling element 3. That is to
say, when the pulling element 3 has not been moved relative to the
sliding element 1 yet and is substantially horizontally placed on
the first sliding portion 11, the elastic portion 23 of the elastic
element 2 can downwardly abut against the concave region 3121 of
the abutting section 312, and the elastic portion 23 of the elastic
element 2 can be partially received inside the concave region 3121
of the abutting section 312. In addition, referring to FIG. 9 and
FIG. 10, when the pulling element 3 has been moved relative to the
sliding element 1 so as to make the pulling element 3 substantially
perpendicular to the first sliding portion 11 (that is to say, the
pulling element 3 shown as a horizontal state can be changed into
the pulling element 3 shown as a vertical state by pulling the
pulling element 3 up), the abutting section 312 of the pivot
portion 31 of the pulling element 3 can upwardly abut against the
elastic portion 23 of the elastic element 2, and the two abutting
portions 32 of the pulling element 3 can respectively abut against
the two stop portions 15, so that the pulling element 3 is blocked
or restricted by the two stop portions 15 and cannot be moved
forwardly. In other words, when the pulling element 3 has been
moved relative to the sliding element 1 so as to make the pulling
element 3 substantially perpendicular to the first sliding portion
11, the abutting region 3122 of the abutting section 312 can
upwardly abut against the elastic portion 23 of the elastic element
2, so that an end portion of the movable portion 22 can be received
inside the through opening 110.
[0031] For example, referring to FIG. 1 to FIG. 5, one of the two
riveted portions 14 includes two first bending sections 141
correspondingly disposed on the first sliding portion 11, and one
of the two pivot sections 311 of the pivot portion 31 is partially
covered or enclosed by the two first bending sections 141 so as to
restrict the pulling element 3 and prevent the pulling element 3
from being separated from the sliding element 1 (that to say, the
pulling element 3 does not escape from the sliding element 1). In
addition, another one of the two riveted portions 14 includes two
second bending sections 142 correspondingly disposed on the first
sliding portion 11, and another one of the two pivot sections 311
of the pivot portion 31 is partially covered by the two second
bending sections 142 so as to restrict the pulling element 3 and
prevent the pulling element 3 from being separated from the sliding
element 1 (that to say, the pulling element 3 does not escape from
the sliding element 1). Therefore, by virtue of "the two first
bending sections 141 of one of the two riveted portions 14 being
mated with one of the two pivot sections 311 of the pivot portion
31" and "the two second bending sections 142 of another one of the
two riveted portions 14 being mated with another one of the two
pivot sections 311 of the pivot portion 31", the pulling element 3
can be pivotally disposed on the first sliding portion 11. However,
the aforementioned description for the riveted portion 14, the
first bending section 141 and the second bending section 142 is
merely an example and is not meant to limit the scope of the
present disclosure.
[0032] It should be noted that one of the two stop portions 15 is
tightly connected to one of the two first bending portions 141, and
another one of the two stop portions 15 is tightly connected to one
of the two second bending portions 142 as shown in FIG. 1, FIG. 3,
and FIG. 5 to FIG. 7.
[0033] For example, referring to FIG. 1 and FIG. 3, the stop
portion 15 has an inner curved surface 1501 and an outer curved
surface 1502 opposite to the inner curved surface 1501, the first
bending section 141 has a first inner curved surface 1411 and a
first outer curved surface 1412 opposite to the first inner curved
surface 1411, and the second bending section 142 has a second inner
curved surface 1421 and a second outer curved surface 1422 opposite
to the second inner curved surface 1421. In addition, a contour of
the inner curved surface 1501 of one of the two stop portions 15 is
substantially the same to and partially flush with a contour of the
first inner curved surface 1411 of one of the two first bending
sections 141, and a contour of the inner curved surface 1501 of
another one of the two stop portions 15 is substantially the same
to and partially flush with a contour of the second inner curved
surface 1421 of one of the two second bending sections 142.
Moreover, a contour of the outer curved surface 1502 of one of the
two stop portions 15 is substantially the same to a contour of the
first outer curved surface 1412 of one of the two first bending
sections 141, and a contour of the outer curved surface 1502 of
another one of the two stop portions 15 is substantially the same
to a contour of the second outer curved surface 1422 of one of the
two second bending sections 142. However, the aforementioned
description for the stop portion 15, the first bending section 141
and the second bending section 142 is merely an example and is not
meant to limit the scope of the present disclosure.
[0034] For example, referring to FIG. 6 and FIG. 7, a width W of a
bottom side of the stop portion 15 is smaller than a width W1 of a
bottom side of the first bending section 141 and a width W2 of a
bottom side of the second bending section 142, and a height H of
the stop portion 15 is smaller than a height H1 of the first
bending section 141 and a height H2 of the second bending section
142. However, the aforementioned description for the stop portion
15, the first bending section 141 and the second bending section
142 is merely an example and is not meant to limit the scope of the
present disclosure.
Second Embodiment
[0035] Referring to FIG. 11, a second embodiment of the present
disclosure provides a zipper head assembly structure (not labeled)
and a sliding element 1 thereof. Comparing FIG. 11 with FIG. 5, the
difference between the second embodiment and the first embodiment
is as follows: in the second embodiment, one of the two stop
portions 15 is separate from and adjacent to one of the two first
bending portions 141, and another one of the two stop portions 15
is separate from and adjacent to one of the two second bending
portions 142. That is to say, one of the two stop portions 15 can
be tightly connected to one of the two first bending portions 141
(such as in the first embodiment as shown in FIG. 5) or can be
separated from and adjacent to one of the two first bending
portions 141 (such as in the second embodiment as shown in FIG.
11), and another one of the two stop portions 15 can be tightly
connected to one of the two second bending portions 142 (such as in
the first embodiment as shown in FIG. 5) or can be separated from
and adjacent to one of the two second bending portions 142 (such as
in the second embodiment as shown in FIG. 11), according to
different requirements.
[0036] In conclusion, by virtue of "the sliding element 1 including
a first sliding portion 11, two riveted portions 14 disposed on the
first sliding portion 11, and two stop portions 15 respectively
adjacent to the two riveted portions 14" and "the pulling element 3
including a pivot portion 13 movably disposed on the first sliding
portion 11 and two abutting portions 32 respectively connected to
two opposite sides of the pivot portion 31", when the pulling
element 3 has been moved relative to the sliding element 1 so as to
make the pulling element 3 substantially perpendicular to the first
sliding portion 11, the two abutting portions 32 of the pulling
element 3 respectively abut against the two stop portions 15, so
that the pulling element 3 can be blocked or restricted by the two
stop portions 15.
[0037] Furthermore, by virtue of "the two riveted portions 14 being
disposed on the first sliding portion 11" and "the two stop
portions 15 being respectively adjacent to the two riveted portions
14", when the pulling element 3 has been moved relative to the
sliding element 1 so as to make the pulling element 3 substantially
perpendicular to the first sliding portion 11, the two abutting
portions 32 of the pulling element 3 respectively abut against the
two stop portions 15, so that the pulling element 3 can be blocked
or restricted by the two stop portions 15.
[0038] The foregoing description of the exemplary embodiments of
the disclosure has been presented only for the purposes of
illustration and description and is not intended to be exhaustive
or to limit the disclosure to the precise forms disclosed. Many
modifications and variations are possible in light of the above
teaching.
[0039] The embodiments were chosen and described in order to
explain the principles of the disclosure and their practical
application so as to enable others skilled in the art to utilize
the disclosure and various embodiments and with various
modifications as are suited to the particular use contemplated.
Alternative embodiments will become apparent to those skilled in
the art to which the present disclosure pertains without departing
from its spirit and scope.
