DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0023] The embodiments of "a zipper head assembly structure and a
sliding assembly thereof" of the instant disclosure are described.
Other advantages and objectives of the instant disclosure can be
easily understood by one skilled in the art from the disclosure.
The instant disclosure can be applied in different embodiments.
Various modifications and variations can be made to various details
in the description for different applications without departing
from the scope of the instant disclosure. The drawings of the
instant disclosure are provided only for simple illustrations, but
are not drawn to scale and do not reflect the actual relative
dimensions. The following embodiments are provided to describe in
detail the concept of the instant disclosure, and are not intended
to limit the scope thereof in any way.
[0024] Referring to FIG. 1 to FIG. 6, one of embodiments of the
instant disclosure provides a sliding assembly 1 (such as a sliding
head, or a slide fastener head), and the sliding assembly 1
comprises a base portion 10, a first lateral wall portion 11, a
second lateral wall portion 12, a seat portion 13, a retaining
member 14 (such as a hook body or a horse-like hook), a spring
component 15, and a cover sheet 16.
[0025] First, referring to FIG. 1 to FIG. 3, the first lateral wall
portion 11 and the second lateral wall portion 12 are respectively
extended upwardly from two opposite lateral sides of the base
portion 10, and the first lateral wall portion 11 and the second
lateral wall portion 12 correspond to each other and are connected
to a front side portion 101 of the base portion 10. The seat
portion 13 is disposed on the base portion 10 and is connected to a
rear side portion 102 of the base portion 10, and the seat portion
13 has a positioning through hole 130 formed between the first
lateral wall portion 11 and the second lateral wall portion 12. The
cover sheet 16 is fixedly disposed on the seat portion 13, and the
spring component 15 is disposed inside the seat portion 13 and
between the cover sheet 16 and the retaining member 14. The
retaining member 14 is movably disposed on the seat portion 13 and
movably contacts the spring component 15, and the retaining member
14 has a positioning portion 140 disposed on an end portion thereof
and passing through the positioning through hole 130.
[0026] More particularly, referring to FIG. 1 to FIG. 3, the spring
component 15 has a first contacting side 151 directly contacting
the retaining member 14 and a second contacting side 152 opposite
to the first contacting side 151, and the cover sheet 16 has a
first end portion 161 directly contacting the second contacting
side 152 of the spring component 15 and a second end portion 162
opposite to the first end portion 161 and separated from the
retaining member 14. That is to say, the cover sheet 16 cannot
directly contact any portion of the retaining member 14. In
addition, the retaining member 14 has an embedded portion 141
opposite to the positioning portion 140 and disposed inside a
receiving groove 131 of the seat portion 13 and a concave abutting
portion 142 disposed between the positioning portion 140 and the
embedded portion 141 and directly contacting the first contacting
side 151 of the spring component 15, and the first end portion 161
of the cover sheet 16 has a position-limiting groove 1610 for
receiving the second contacting side 152 of the spring component
15. Please note, as shown in FIG. 3, the embedded portion 141 of
the retaining member 14 is downwardly pressed by the spring
component 15, so as to keep the embedded portion 141 of the
retaining member 14 to be received inside receiving groove 131.
Hence, the retaining member 14 can be moved downwardly (as shown in
FIG. 8) or upwardly (as shown in FIG. 9) relative to the embedded
portion 141 as a rotary shaft.
[0027] More particularly, referring to FIG. 4 and FIG. 5, the first
lateral wall portion 11 has a first inner surface 111 and a first
outer surface 112 opposite to (oppositely arranged to) the first
inner surface 111, and the second lateral wall portion 12 has a
second inner surface 121 corresponding to the first inner surface
111 and a second outer surface 122 opposite to the second inner
surface 121. In addition, a first thickness H1 between the first
inner surface 111 and the first outer surface 112 of the first
lateral wall portion 11 is smaller than a second thickness H2
between the second inner surface 121 and the second outer surface
122 of the second lateral wall portion 12.
[0028] For example, the first inner surface 111 of the first
lateral wall portion 11 is divided into a first primary inner
surface 1111 and a first secondary inner surface 1112, and the
second inner surface 121 of the second lateral wall portion 12 is
divided into a second primary inner surface 1211 facing the first
primary inner surface 1111 and a second secondary inner surface
1212 facing the first secondary inner surface 1112. In addition, a
first primary thickness H11 between the first primary inner surface
1111 and the first outer surface 112 of the first lateral wall
portion 11 is smaller than a second primary thickness H21 between
the second primary inner surface 1211 and the second outer surface
122 of the second lateral wall portion 12, and a first secondary
thickness H12 between the first secondary inner surface 1112 and
the first outer surface 112 of the first lateral wall portion 11 is
smaller than a second secondary thickness H22 between the second
secondary inner surface 1212 and the second outer surface 122 of
the second lateral wall portion 12.
[0029] More particularly, referring to FIG. 4 and FIG. 5, the base
portion 10 has a first symmetric center line L1 (i.e., a symmetry
centerline or a symmetrical central line), and the seat portion 13
has a second symmetric center line L2. The first symmetric center
line L1 can pass through a geometric center point P (as shown in
FIG. 4) of the positioning through hole 130, and the second
symmetric center line L2 of the seat portion 13 is horizontally
moved relative to the first symmetric center line L1 of the base
portion 10 by a predetermined horizontal offset S and along a
horizontal direction from the second lateral wall portion 12 to the
first lateral wall portion 11. For example, the predetermined
horizontal offset S from the second symmetric center line L2 of the
seat portion 13 to the first symmetric center line L1 of the base
portion 10 can conform to the following formula: S=(H2-H1)/2, in
which S is the predetermined horizontal offset, H1 is the first
thickness, and H2 is the second thickness.
[0030] As shown in FIG. 4 or FIG. 5, it is worth mentioning that
when the first symmetric center line L1 is used as a symmetrical
baseline, the first outer surface 112 of the first lateral wall
portion 11 and the second outer surface 122 of the second lateral
wall portion 12 are symmetrically disposed relative to the first
symmetric center line L1 (i.e., the first outer surface 112 and the
second outer surface 122 are symmetrically disposed on opposite
sides of the first symmetric center line L1). In addition, when the
second symmetric center line L2 is used as a symmetrical baseline,
the first primary inner surface 1111 of the first inner surface 111
of the first lateral wall portion 11 and the second primary inner
surface 1211 of the second inner surface 121 of the second lateral
wall portion 12 are symmetrically disposed relative to the second
symmetric center line L2 (i.e., the first primary inner surface
1111 and the second primary inner surface 1211 are symmetrically
disposed on opposite sides of the second symmetric center line L2),
or the first secondary inner surface 1112 of the first inner
surface 111 of the first lateral wall portion 11 and the second
secondary inner surface 1212 of the second inner surface 121 of the
second lateral wall portion 12 are symmetrically disposed relative
to the second symmetric center line L2 (i.e., the first secondary
inner surface 1112 and the second secondary inner surface 1212 are
symmetrically disposed on opposite sides of the second symmetric
center line L2).
[0031] Furthermore, referring to FIG. 4, FIG. 5, and FIG. 6, the
positioning portion 140 of the retaining member 14 has a cutting
edge 1400 (such as a cutting plane) concaved on a lateral surface
thereof and along an opposite direction opposite to the horizontal
direction from the second lateral wall portion 12 to the first
lateral wall portion 11, so that the positioning portion 140 is
diverged (deviated) from the second symmetric center line L2 and
adjacent to the first symmetric center line L1 (as shown in FIG.
5).
[0032] Referring to FIG. 7 to FIG. 11, one of embodiments of the
instant disclosure provides a zipper head assembly structure Z
disposed on a zipper teeth structure 3 (such as a zipper tape or a
zipper strip) including a first zipper teeth member 31 (such as a
zipper rack or a toothed bar) and a second zipper teeth member 32
mated with each other. The zipper head assembly structure Z
comprises a sliding assembly 1 and a pulling member 2 (such as a
pull tab or a pull piece).
[0033] Referring to FIG. 1, FIG. 7 and FIG. 10, the first lateral
wall portion 11 and the second lateral wall portion 12 are
respectively extended upwardly from two opposite lateral sides of
the base portion 10, and the first lateral wall portion 11 and the
second lateral wall portion 12 correspond to each other and are
connected to a front side portion 101 of the base portion 10. The
seat portion 13 is disposed on the base portion 10 and is connected
to a rear side portion 102 of the base portion 10, and the seat
portion 13 has a positioning through hole 130 formed between the
first lateral wall portion 11 and the second lateral wall portion
12. The cover sheet 16 is fixedly disposed on the seat portion 13,
and the spring component 15 is disposed inside the seat portion 13
and between the cover sheet 16 and the retaining member 14. The
retaining member 14 is movably disposed on the seat portion 13 and
movably contacts the spring component 15, and the retaining member
14 has a positioning portion 140 disposed on an end portion thereof
and passing through the positioning through hole 130. In addition,
the pulling member 2 is movably mated with the retaining member 14,
for example, the pulling member 2 includes a movable piece 21
disposed on an end portion 20 thereof and movably mated with the
retaining member 14.
[0034] More particularly, referring to FIG. 10 and FIG. 11, the
first zipper teeth member 31 includes a first zipper teeth carrier
310 and a plurality of first zipper teeth 311 disposed on the first
zipper teeth carrier 310, and the second zipper teeth member 32
includes a second zipper teeth carrier 320 and a plurality of
second zipper teeth 321 disposed on the second zipper teeth carrier
320. In addition, as shown in FIG. 11, each of the first zipper
teeth 311 can be retained between two adjacent second zipper teeth
321. When one of the first zipper teeth 311 is retained between two
of the second zipper teeth 321 to form a gap P between the first
zipper tooth 311 and the two second zipper teeth 321 for receiving
the positioning portion 140 (i.e., the positioning portion 140 is
inserted into the gap (g) between the two adjacent second zipper
teeth 321), the zipper head assembly structure Z can be accurately
positioned on the zipper teeth structure 3 by matching the
positioning portion 140 and the gap (g).
[0035] In conclusion, the cover sheet 16 is disposed on the seat
portion 13, and the spring component 15 is disposed inside the seat
portion 13 and between the cover sheet 16 and the retaining member
14, so that the retaining member 14 can be movably disposed on the
seat portion 13 for movably contacting the spring component 15.
[0036] More particularly, the spring component 15 has a first
contacting side 151 directly contacting the retaining member 14 and
a second contacting side 152 opposite to the first contacting side
151, and the cover sheet 16 has a first end portion 161 directly
contacting the second contacting side 152 of the spring component
15 and a second end portion 162 opposite to the first end portion
161 and separated from the retaining member 14, so that the spring
component 15 can be fixedly disposed inside the seat portion 13 and
between the cover sheet 16 and the retaining member 14, so as to
prevent the spring component 15 from being separated from between
the cover sheet 16 and the retaining member 14.
