structure and a movable cover body thereof, and more particularly
to a zipper head assembly structure for decreasing assembling
resistance and a movable cover body thereof.
[0003] 2. Description of Related Art
[0004] In general, zippers are basic elements in clothing or
accessories. Compare to buttons, the zippers are easier to use. A
conventional zipper comprises a zipper head and a tape. The zipper
head works with the tape to allow the pulling action. Recently, the
zipper has been used commonly for clothing, pants, backpack, and
other accessories.
SUMMARY OF THE INVENTION
[0005] One aspect of the instant disclosure relates to a zipper
head assembly structure for decreasing assembling resistance and a
movable cover body thereof.
[0006] One of the embodiments of the instant disclosure provides a

extended outwardly from the major portion and respectively slidably
disposed inside the two sliding grooves, a positioning portion
extended outwardly from the major portion and movably passing
through the through opening, two pivotal portions extended
outwardly from the major portion and respectively pivotally
disposed inside the two pivotal grooves, an extending tail portion
extended outwardly from the major portion and disposed inside the
receiving groove, and two assembly chamfers respectively disposed
on two inner corners of the two pivotal portions and respectively
corresponding to the two inclined assembly surfaces.
[0008] Another one of the embodiments of the instant disclosure
provides a zipper head assembly structure for decreasing assembling
resistance, comprising: a sliding member, a movable cover body, and
a pull member. The movable cover body is movably disposed on the
first sliding body, and the pull member has an end portion movably
mated with the movable cover body. More precisely, the sliding
member has a first convex body disposed on the first sliding body
and a second convex body disposed on the first sliding body and
corresponding to the first convex body, and the second convex body
has a second main portion disposed on the first sliding body, two
pivotal grooves respectively disposed on two opposite lateral sides
of the second main portion, and two inclined assembly surfaces
respectively disposed on the two opposite lateral sides of the
second main portion and respectively disposed above the two pivotal
grooves. The movable cover body has a major portion, two pivotal
portions extended outwardly from the major portion and respectively
pivotally disposed inside two pivotal grooves, and two assembly
chamfers respectively disposed on two inner corners of the two
pivotal portions and respectively corresponding to the two inclined
assembly surfaces.
[0009] Yet another one of the embodiments of the instant disclosure
provides a movable cover body for decreasing assembling resistance,
comprising: a major portion, two sliding portions extended
outwardly from the major portion and respectively slidably disposed
inside two sliding grooves, a positioning portion extended
outwardly from the major portion and movably passing through a
through opening, two pivotal portions extended outwardly from the
major portion and respectively pivotally disposed inside two
pivotal grooves, an extending tail portion extended outwardly from
the major portion and disposed inside a receiving groove, and two
assembly chamfers respectively disposed on two inner corners of the
two pivotal portions and respectively corresponding to two inclined
assembly surfaces.
[0010] More precisely, the first convex body has two vertical
convex ribs respectively disposed inside the two sliding grooves,
and the two sliding portions respectively movably contact the two
vertical convex ribs, wherein the second convex body has two first
convex points respectively disposed inside the two pivotal grooves,
and the two pivotal portions respectively movably contact the two
first convex points, wherein the second convex body has at least
one second convex point disposed inside the receiving groove, and
the extending tail portion movably contacts the at least one second
convex point.
[0011] More precisely, the major portion has a first plane plate
and two second plane plates respectively extended downwardly from

surface connected with the second surface, and a fourth surface
connected with the third surface, wherein the receiving groove is
disposed on the carrier body and between the two lateral walls, and
the two inclined assembly surfaces are respectively inclinedly
disposed on the two lateral walls.
[0013] Because the designs of "the two pivotal portions extended
outwardly from the major portion and respectively pivotally
disposed inside the two pivotal grooves" and "the two assembly
chamfers respectively disposed on two inner corners of the two
pivotal portions and respectively corresponding to the two inclined
assembly surfaces", the assembling resistance of assembling the
movable cover body 2 on the sliding member 1 is decreased due to
the low-resistance surface contact between the assembly chamfer 25
and the inclined assembly surface 152, so as to prevent the sliding
member 1 from being scraped by the movable cover body 2. Hence, the
two assembly chamfers 25 can respectively slip through the two
inclined assembly surfaces 152 easily in order to assemble the
movable cover body 2 on the sliding member 1.

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.
[0027] Referring to FIG. 1 to FIG. 8, the instant disclosure
provides a zipper head assembly structure Z for decreasing
assembling resistance, comprising: a sliding member 1 (such as a
sliding head or a slide fastener head), a movable cover body 2, and
a pull member 3 (such as a pull tab or a pull piece).
[0028] First, referring to FIG. 1 and FIG. 2, the sliding member 1
has a first sliding body 11, a second sliding body 12 opposite to
the first sliding body 11, and a connection body 13 connected
between the first sliding body 11 and the second sliding body 12.
More precisely, the sliding member 1 has a first convex body 14
disposed on the first sliding body 11, a second convex body 15
disposed on the first sliding body 11 and corresponding to the
first convex body 14, and at least one through opening 16 passing
through the first sliding body 11 and disposed between the first
convex body 14 and the second convex body 15. In addition, the
first convex body 14 has a first main portion 140 disposed on the
first sliding body 11, two sliding grooves 141 respectively
disposed on two opposite lateral sides of the first main portion
140, and at least one structure reinforcing rib 142 disposed on the
first sliding body 11 and connected with the first main portion
140. Moreover, the second convex body 15 has a second main portion
150 disposed on the first sliding body 11, two pivotal grooves 151
respectively disposed on two opposite lateral sides of the second
main portion 150, two inclined assembly surfaces 152 respectively
disposed on the two opposite lateral sides of the second main
portion 150 and respectively disposed above the two pivotal grooves
151, and a receiving groove 153 disposed on the second main portion
150 and extended onto a front side of the second main portion
150.
[0029] Following the above description, for example, the second
main portion 150 has a carrier body 1501 and two lateral walls 1502
respectively disposed on two opposite lateral sides of the carrier
body 1501. In addition, the carrier body 1501 has a first surface
15011, a second surface 15012 connected with the first surface
15011, a third surface 15013 connected with the second surface
15012, and a fourth surface 15014 connected with the third surface
15013 and disposed on the front side of the second main portion
150. The receiving groove 153 is disposed on the carrier body 1501
and between the two lateral walls 1502, and the two inclined
assembly surfaces 152 are respectively inclinedly disposed on the
two lateral walls 1502.
[0030] Moreover, referring to FIG. 3, FIG. 4, and FIG. 5, the
movable cover body 2 is movably disposed on the first sliding body
11, and the pull member 3 has an end portion 30 movably mated with
the movable cover body 2. In addition, the movable cover body 2 has
a major portion 20, two sliding portions 21 extended outwardly from
the major portion 20 and respectively slidably disposed inside the
two sliding grooves 141, a positioning portion 22 extended
outwardly from the major portion 20 and movably passing through the
through opening 16, two pivotal portions 23 extended outwardly from
the major portion 20 and respectively pivotally disposed inside the
two pivotal grooves 151, an extending tail portion 24 extended
outwardly from the major portion 20 and disposed inside the
receiving groove 153, and two assembly chamfers 25 (such as two
assembly bevels) respectively disposed on two inner corners of the
two pivotal portions 23 and respectively corresponding to the two
inclined assembly surfaces 152. For example, the inclined assembly
surface 152 has a first predetermined inclination such as 45
degrees relative to the horizontal surface, the assembly chamfer 25
has a second predetermined inclination such as 45 degrees relative
to the horizontal surface. When the first predetermined inclination
is the same as or similar to the second predetermined inclination,
the assembling resistance between the assembly chamfer 25 and the
inclined assembly surface 152 is decreased. Hence, the two assembly
chamfers 25 can respectively slip through the two inclined assembly
surfaces 152 easily in order to assemble the movable cover body 2
on the sliding member 1.
[0031] More precisely, referring to FIG. 1 and FIG. 2, the major
portion 20 has a first plane plate 201 and two second plane plates
202 respectively extended downwardly from the two opposite lateral
sides of the first plane plate 201. The two sliding portions 21 are
respectively extended outwardly from two first lateral sides 2001
of the two second plane plates 202, the positioning portion 22 is
extended downwardly from a bottom side 2000 of one of the two
second plane plates 202, the two pivotal portions 23 are
respectively extended outwardly from two second lateral sides 2002
of the two second plane plates 202, and the extending tail portion
24 is extended downwardly from an end side of the first plane plate
201.
[0032] More precisely, referring to FIG. 1, FIG. 2, FIG. 6, and
FIG. 7, the first convex body 14 has two vertical convex ribs 143
respectively disposed inside the two sliding grooves 141, and the
two sliding portions 21 respectively movably contact the two
vertical convex ribs 143. Referring to FIG. 1, FIG. 2, FIG. 6, and
FIG. 8, the second convex body 15 has two first convex points 154
respectively disposed inside the two pivotal grooves 151, and the
two pivotal portions 23 respectively movably contact the two first
convex points 154. In addition, the second convex body 15 has at
least one second convex point 155 disposed inside the receiving
groove 153, and the extending tail portion 24 movably contacts the
at least one second convex point 155.
[0033] Referring to FIG. 9, FIG. 10, and FIG. 11, FIG. 9 shows a
partial, lateral, schematic view of the movable cover body 2 of the
zipper head assembly structure Z preparing to be assembled on the
sliding member 1 (that is to say that the assembly chamfer 25
prepares to contact the inclined assembly surface 152) according to
the instant disclosure, FIG. 10 shows a partial, lateral, schematic
view of the movable cover body 2 of the zipper head assembly
structure Z slipping on the sliding member 1 (that is to say that
the assembly chamfer 25 has contacted the inclined assembly surface
152) according to the instant disclosure, and FIG. 11 shows a
partial, lateral, schematic view of the movable cover body 2 of the
zipper head assembly structure Z having been assembled on the
sliding member 1 (that is to say that the assembly chamfer 25 has
slipped through the inclined assembly surface 152) according to the
instant disclosure. Referring to FIG. 9 and FIG. 10, the assembling
resistance of assembling the movable cover body 2 on the sliding
member 1 is decreased due to the low-resistance surface contact
between the assembly chamfer 25 and the inclined assembly surface
152, so as to prevent the sliding member 1 from being scraped by
the movable cover body 2. Hence, the two assembly chamfers 25 can
respectively slip through the two inclined assembly surfaces 152
easily in order to assemble the movable cover body 2 on the sliding
member 1.
[0034] In conclusion, Because the designs of "the two pivotal
portions 23 extended outwardly from the major portion 20 and
respectively pivotally disposed inside the two pivotal grooves 151"
and "the two assembly chamfers 25 respectively disposed on two
inner corners of the two pivotal portions 23 and respectively
corresponding to the two inclined assembly surfaces 152", the
assembling resistance of assembling the movable cover body 2 on the
sliding member 1 is decreased due to the low-resistance surface
contact between the assembly chamfer 25 and the inclined assembly
surface 152, so as to prevent the sliding member 1 from being
scraped by the movable cover body 2.
[0035] For example, the inclined assembly surface 152 has a first
predetermined inclination such as 45 degrees relative to the
horizontal surface, the assembly chamfer 25 has a second
predetermined inclination such as 45 degrees relative to the
horizontal surface. When the first predetermined inclination is the
same as or similar to the second predetermined inclination, the
assembling resistance between the assembly chamfer 25 and the
inclined assembly surface 152 is decreased. Hence, the two assembly
chamfers 25 can respectively slip through the two inclined assembly
surfaces 152 easily in order to assemble the movable cover body 2
on the sliding member 1.
[0036] The aforementioned descriptions merely represent the
preferred embodiments of the instant disclosure, without any
intention to limit the scope of the instant disclosure which is
fully described only within the following claims. Various
equivalent changes, alterations or modifications based on the
claims of the instant disclosure are all, consequently, viewed as
being embraced by the scope of the instant disclosure.
