FIELD
[0002] The present application relates to the technical field of zippers, and in particular
to a two-way insertion assembly.
BACKGROUND
[0003] In daily life, a two-way zipper is widely used. Before a slider of the two-way zipper
is pulled, it generally needs two hands to align two sliders, which is not easy to
operate. An inserting action can only be performed after the alignment of the two
sliders is repeatedly confirmed, and then the two-way zipper can be closed. Even if
the two sliders are pulled in place, they are prone to shaking, causing the sliders
to bite into an edge of a tape. Therefore, the insertion pin cannot be inserted quickly
at one time, which is difficult to use.
[0004] At present, a two-way insertion assembly on the market generally realizes stopping
the slider by increasing the strength of the two-way insertion assembly and the tape
and increasing the hardness of the tape. However, the effect by the above solution
is not ideal, and it is still impossible to ensure a precise and effective alignment
of the two sliders. The problems of the slider shaking laterally and biting the tape
are not effectively solved, which cannot ensure the retainer to be quickly and stably
inserted into the slider.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The following will provide a clear and complete description of the technical solution
in the embodiments of the present application in conjunction with the accompanying
drawings. Obviously, the described embodiments are only a part of the embodiments
of the present application, not all of them. Based on the embodiments in the present
application, all other embodiments obtained by those skilled in the art without paying
a creative work will fall within the scope of the present application.
[0020] In order to enable those skilled in the art to better understand the present application,
a further detailed explanation of the present application will be provided below in
conjunction with the accompanying drawings and embodiments.
[0021] A two-way insertion assembly is provided in the present application, which includes
an insertion pin 20 and a retainer 30. Two sliders 10 are mounted on the retainer
30. When the two sliders 10 are moved in place, the insertion pin 20 is inserted into
inner cavities of the two sliders 10. A retainer side base 40 is provided on the tape
at a side of the retainer 30. The retainer side base 40 is located outside the retainer
30, and a retainer side passage is formed there between. A guide passage for inserting
the insertion pin 20 is provided by the retainer side passage, so that the insertion
pin 20 can be accurately inserted into the guide passage. The retainer side passage
is provided with a limiter 501, which can laterally limit the slider that is moved
in place so as to prevent the slider from shaking laterally.
[0022] The two sliders 10, i.e., a top slider and a bottom slider, are located on the retainer
30 and the retainer side base through the retainer side passage. Two sliders on a
conventional retainer may shake along with the swing of the clothing, which causes
a positional deviation and results in a misalignment of the inner cavities of two
sliders, thus, it is difficult to quickly and effectively insert the insertion pin
20 into the inner cavities of the two sliders.
[0023] For this, when the top slider in the present application passes through the side
base, the retainer side passage guides the movement of the slider, making it easier
for the insertion pin 20 to be inserted into the inner cavities of the two sliders.
The limiter 501 blocks the lateral movement of the sliders, assists and secures the
two sliders, ensuring the two sliders not to shake laterally or deviate on the insertion
pin 20.
[0024] In the two-way insertion assembly provided in the present application, the two sliders
are stably connected, which are not prone to deviation, and thus it is easy to operate
without an additional manually positioning, and it only needs to pull the two sliders
to the bottom. Therefore, the manufacturing process is simple with minimum changes
to the entire production process.
[0025] The retainer side passage is a passage with a bottom portion. The bottom portion
is formed on the tape by stamping with a stamping die. The retainer side base 40 and
the retainer 30 are connected through the bottom portion, that is, a passage is formed
between the retainer side base 40, the retainer 30, and the bottom portion, thus the
passage with the bottom portion is formed.
[0026] The bottom portion of the passage has a certain thickness to fill a biting space
between a tape gap of the two sliders and the retainer side passage, increase the
friction resistance of the slider, increase a forward friction force of the two sliders
10, and prevent the slider that is in place from shifting fore and aft, which further
ensures the movement stability of the slider.
[0027] Referring to FIG. 1, FIG. 1 is a schematic view of a two-way insertion assembly according
to a first embodiment of the present application. In the figure, the retainer side
passage is substantially located in the middle of the retainer side base 40 and is
provided with the limiter 501. The limiter 501 is in a flared opening shape, which
implements a guiding function to the movement and a lateral position-limit function
when the slider being in place and thus can effectively limit the slider in combination
with the frictional force between the bottom portion of the passage and the slider.
[0028] FIG. 2 is a schematic view of a two-way insertion assembly according to a second
embodiment of the present application. In the figure, the retainer side passage is
provided with a first guide portion 502 at an entry end of the slider. The first guide
portion 502 is tapered along the entry direction of the slider and smoothly transitioned
to the limiter 501 next to the first guide portion 502. The first guide portion 502
facilitates the entry of the slider, and the limiter 501 limits the slider 10 that
is in place, making the zipping action of the slider smoother and more efficient and
convenient.
[0029] Referring to FIG. 3 and FIG. 4. FIG. 3 is a schematic structural view of a two-way
insertion assembly according to a third embodiment of the present application, and
FIG. 4 is a schematic structural view of the insertion pin, the retainer, and the
two sliders in FIG. 3 in state of meshing.
[0030] In FIG. 3 and FIG. 4, the retainer side passage is provided with a second guide portion
503 at a movement terminal end of the slider in order to guide the entry of the slider.
Along the zipping direction, the second guide portion 503 is located at a leading
end of the first guide portion 502, and the second guide portion 503 is gradually
flared along the entry direction of the slider. The limiter 501 is formed between
the first guide portion 502 and the second guide portion 503, forming a flared opening
shape, and the limiter 501, the first guide portion 502 and the second guide portion
503 are transitioned smoothly. The two sliders that are in place are shown in FIG.
4.
[0031] In this embodiment, the second guide 503 is further provided based on the first guide
502, which facilitates guiding the slider to entre and exit. The second guide 503
has a width greater than that of the limiter 501 in the middle. The first guide 502
and the second guide 503 implement a function of guiding, which facilitates the entry
of the two sliders. The limiter 501 blocks the lateral movement and shaking of the
slider, which implements a function of limiting so as to prevent the slider from collision
with the retainer side base 40. In addition, the limiter 501 limits the two sliders
10 that is in place to prevent the slider from shaking.
[0032] Referring to FIG. 5, FIG. 5 is a schematic structural view of a two-way insertion
assembly according to a fourth embodiment of the present application.
[0033] In the figure, the retainer side base 40 is sequentially provided with a first guide
502, a limiter 501, and a second guide 503 along an insertion direction of the slider.
The leading end of the retainer 30 and the leading end of the second guide 503 are
extended forward, respectively, to form a guide slot 504, which can guide a quick
entry of the slider and form a barrier at the terminal end to prevent the slider from
falling off due to excessive force.
[0034] To ensure the use safety, extension portions of the retainer 30 and the second guide
503 are an arc structure without edges and corners in order to avoid scratching the
user.
[0035] In addition, in order to ensure a good match between the guide slot 504 and the arc
angle outside the leading end of the slider, the guide slot 504 is a U-shaped slot,
which is compatible with the arc angle of the leading end of the slider, and the U-shaped
slot matches with the arc angle of the leading end of the slider, which can accommodate
the slider and implement a position limit to the slider. It should be noted that the
guide slot 504 is not limited to a U-shaped structure. The specific structure of the
guide slot 504 should be configured according to actual needs, which is not limit
herein.
[0036] Exemplarily, the retainer side base 40, the bottom portion, and the retainer 30 are
integrated for easy processing and ensuring strength.
[0037] Referring to FIG. 6, FIG. 6 is a schematic structural view of a two-way insertion
assembly according to a fifth embodiment of the present application.
[0038] Based on any previous embodiments, a pin side base 60 may be provided on the tape
at the side of the insertion pin 20. A pin side passage is formed between the pin
side base 60 and the insertion pin 20. The limiter 501 is provided on the pin side
passage, and the first guide 502 and/or the second guide 503 may be further provided
on the pin side passage. The principle of the pin side passage is the same as that
of the retainer side passage. The pin side passage is provided to implement a synchronous
guiding and position limiting to both sides of the two sliders 10, thereby improving
the smoothness of the two sliders 10.
[0039] In an embodiment, the pin side base 60 and the retainer side base 40 are symmetrically
arranged, thereby ensuring synchronous guiding and limiting to the two sides of the
two sliders 10, which further improves the pulling smoothness of the two sliders 10
and prevents a motion blockage.
