Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to luggage technology and more
particularly, to a coupling structure of retractable
handle-equipped luggage.
2. Description of the Related Art
[0002] U.S. patent Ser. No. 15/059,403 (Publication Number
US2017/0261771 A1) discloses a double open end zipper-based
luggage, which is invented by and issued to the present inventor.
The double open end zipper used in the double open end zipper-based
luggage includes first and second zipper tapes respectively
stitched to the N-shaped plastic strips at the first and second
housing members of the luggage housing in reversed directions with
the box and pin of the first zipper tape respectively disposed
adjacent to the pin and box of the second zipper tape subject to
the guidance of a mark line at each N-shaped plastic strip, a seam
allowance constraint block located at an outer rear side of the box
of each of the first and second zipper tapes, and two zipper
sliders respectively coupled to first and second zipper tape.
However, in the zipper slider mounting process (insertion of zipper
tapes into the zipper sliders) during luggage fabrication, it is
necessary to perform the process twice. Further, for enabling the
pull taps of the zipper sliders to be lockable to the customs lock,
the orientation of the pull tap of each zipper slider must be
accurately checked. Customer feedback indicates that workers often
mount the zipper sliders in the wrong direction, or it is difficult
to distinguish the directionality of the pull taps. Actually, the
two zipper sliders on one same zipper tape must be disposed
opposite to each other. For enabling the pull taps of the zipper
sliders to be lockable to the customs lock, the pull taps of the
two zipper sliders must be disposed in reversed directions.
Therefore, the two zipper sliders must not be set in the same
direction. During installation, a mistake may occur. If the two
zipper sliders are installed in the wrong direction, the
installation must be revised. When mounting the zipper sliders, the
worker must simultaneously hold the first and second housing
members in position, which is very laborious and inefficient.
Further, because the cloth strips between the first and second
housing members are flexible, when the user opens the luggage
housing, the first or second housing member being opened will
vibrate relative to the second or first housing member. Further,
the T-shaped protector that is detachably mountable in between the
first and second housing members to shield the boxes of the first
and second zipper tapes does not work like a hinge, thus, the first
and lower housing members cannot be turned relative to each other
through 180 degree angle to a fully open status. Thus, this design
is simply applicable to soft shell luggages but not suitable for
hard shell luggage. The use of this prior art design is subject to
certain restrictions and needs to be improved again.
[0003] U.S. Pat. No. 6,390,259B1 disclosed a retractable but not
detachable wheeled luggage. U.S. Pat. No. 7,641,040B1 also
disclosed a retractable textile apparatus, but can not be separated
completely.
SUMMARY OF THE INVENTION
[0004] The present invention has been accomplished under the
circumstances in view. It is the main object of the present
invention to provide a coupling structure of retractable
handle-equipped luggage, which is applicable to soft and hard shell
luggage and bags, facilitating quick zipper slider installation and
avoiding installation mistakes.
[0005] To achieve this and other objects of the present invention,
the coupling structure of retractable handle-equipped luggage
includes a luggage housing comprising an upper housing member and a
lower housing member equipped with a retractable handle, a double
open end zipper including a second zipper tape stitched to the rim
of the upper housing member, a first zipper tape stitched to the
rim of the lower housing member, a box affixed to each of two
opposite ends of the first zipper tape, a pin affixed to each of
two opposite end of the second zipper tape and two zipper sliders
mounted to the second zipper tape and respectively provided with a
pull tap that is fastenable to a customs lock at the lower housing
member, two detachable flexible buckles stitched to the upper and
lower housing members, and a detachable hinge mounted to the upper
housing member and the lower housing member between the two
detachable flexible buckles. The upper housing member and the lower
housing member can be separated easily by dismounting the first
buckle member and the second buckle member and disengaging the pins
at the second zipper tape from the boxes at the first zipper tape
and then removing the hinge axle of the detachable hinge from the
axle housings of the other hinge plates. If the detachable flexible
buckle is used, the user can manually unfasten the wing nut and
then remove the screw bolt, enabling the upper and lower housing
members to be fully separated. The upper housing member and the
lower housing member can be received together for packaging to
reduce the volume of the luggage. When the upper and lower housing
members of a plurality of luggage housings are packaged and
transported together to the destination, the complete luggage
housings can be quickly and manually assembled without any tools.
This design reduces luggage housing packaging and shipping costs.
When the upper and lower housing members are received and packed
together, the luggage housing can bear high pressure during
transportation, avoiding deformation and damage. The arrangement of
the extension shell 6 between the upper and lower housing members
greatly increases the storage volume of the luggage housing. When
the extension shell is not used, it can be attached to the inside
wall of the luggage housing, facilitating application.

detachable flexible buckles 3 stitched to the upper housing member
11 and the lower housing member 13 (see FIG. 3), and a detachable
hinge 4 mounted to the upper housing member 11 and the lower
housing member 13 between the two detachable flexible buckles 3
(see FIG. 4). The detachable flexible buckle 3 is made of TPU
(thermoplastic polyurethane elastomer rubber), but it can of course
be made of other similar semi-soft thermoplastic materials. The
detachable flexible buckle 3 (see FIGS. 4-7) consists of a first
buckle member 31 and a second buckle member 32. The first buckle
member 31 and the second buckle member 32 are two opposite zigzags.
The first buckle member 31 has three locating grooves 33 located on
a head thereof, and a hook hole 36 in each locating groove 33. The
second buckle member 32 has three necked locating strips 34
extended from a head thereof corresponding to the locating grooves
33 of the first buckle member 31, and a hook pin 35 perpendicularly
downwardly extended from each necked locating strip 34 for hooking
in the hook hole 36 in one respective locating groove 33. Further,
the three necked locating strips 34 of the detachable flexible
buckle 3 can be disposed outside the luggage housing 1 (see FIG.
3), or inside the luggage housing 1 (see FIG. 8). In other words,
the detachable flexible buckle 3 necked locating strips 34 of the
detachable flexible buckle 3 can be disposed inside or outside the
luggage housing 1 according to actual needs.
[0028] The detachable hinge 4 pivotally connects the upper housing
member 11 and the lower housing member together (see FIGS. 9 and
10). As illustrated in FIGS. 12-14, the detachable hinge 4
comprises two identical hinge plates 41, and a hinge axle 44
mounted in between the two hinge plates 41. The hinge plate 41
comprises an axle housing 411, an open side 412, an arched hook
portion 413 suspending in the open side 412, at least one plug rod
4131 located on an inner side of the arched hook portion 413, at
least one engagement hole 4132 cut through opposing left and right
sides of the arched hook portion 413, an axle hole 4111 defined in
the axle housing 411 (see FIG. 13), at least one plug hole 4112
located on a top side of the axle housing 411, and at least one
engagement block 4113 located on one lateral side of the axle
housing 411. The hinge axle 44 has two opposite ends thereof
respectively inserted into the axle holes 4111 of the axle housings
411 of the two hinge plates 41 to pivotally connect the two hinge
plates 41 together, enabling the at least one plug rod 4131 of one
hinge plate 41 to be plugged into the at least one plug hole 4112
of the other hinge plate 41 and the at least one engagement block
4113 of one hinge plate 41 to be engaged into the at least one
engagement hole 4132 of the other hinge plate 41 to achieve a
double blocking effect, prohibiting relative displacement between
the two hinge plates 41 in the axial direction as well as the
transverse direction. When biasing the arched hook portion 413 (in
the arrowhead direction shown in FIG. 12) to disengage the at least
one plug rod 4131 from the corresponding at least one plug hole
4112, the at least one engagement block 4113 is also disengaged
from the corresponding at least one engagement hole 4132, allowing
separation of the two hinge plates 41.
[0029] In the stitching installation of the detachable flexible
buckles 3, the arched hook portions 413 of the two hinge plates 41
are all in the same orientation, both facing the inner cavity of
the luggage housing 1. This arrangement prevents the arched hook
portions 413 of the two hinge plates 41 to be biased by an evil
person from the outside of the luggage housing 1 to disengage the
at least one plug rod 4131 from the at least one plug hole 4112 and
the at least one engagement block 4112 from the at least one
engagement hole 4132. The detachable hinge 4 blocks the gap between
the ends of the double open end zipper 2. The hinge plates 41 are
made of TPU (thermoplastic polyurethane elastomer rubber), but they
can of course be made of other similar semi-soft thermoplastic
materials. The hinge axle 44 is made of metal. The detachable
flexible buckles 3 are made of TPU (thermoplastic polyurethane
elastomer rubber) so that they can be directly stitched to the
upper and lower housing members 11;13. Instead of rivet operations
with traditional metal fittings, the luggage processing is
easier.
Embodiment II
[0030] A coupling structure of retractable handle-equipped luggage
in accordance with a second embodiment of the present invention is
shown. This second embodiment is substantially similar to the
aforesaid first embodiment with the exception of the detachable
hinge. The detachable hinge 5 in this second embodiment is disposed
between the two detachable flexible buckles 3 to vertically or
horizontally couple the upper housing member 11 and the lower
housing member 13 together (see FIGS. 15 and 16). As shown in FIGS.
17 and 18, the detachable hinge 5 comprises two L-shaped flexible
connection plates 51, a cover plate 52 covering the two L-shaped
flexible connection plates 51 at a top side, a cushion plate 53
attached to the two L-shaped flexible connection plates 51 at an
opposing bottom side, a screw bolt 54 vertically downwardly
inserted through the cover plate 52 and the cushion plate 53, and a
wing nut 55 threaded onto the screw bolt 54 and abutted against a
bottom side of the cushion plate 53 opposite to the cover plate 52
to secure the cover plate 52, the L-shaped flexible connection
plates 51 and the cushion plate 53 firmly together. The two
L-shaped flexible connection plates 51 are made of TPU
(thermoplastic polyurethane elastomer rubber), but they can of
course be made of other similar semi-soft thermoplastic materials.
Further, the two L-shaped flexible connection plates 51 are
respectively stitched to the upper housing member 11 and the lower
housing member 13. The pins 24 and boxes 23 of the double open end
zipper 2 are secured to the inside of a -shaped open chamber 521
that is longitudinally defined in the cover plate 52 so that the
cover plate 52 blocks the gap between the opposite side of boxes 23
of the two ends of the double open end zipper 2. Two tracks 511,
511' of inner side of two connection plates 51, 51' are
corresponding to the track 522 of the cover plate 52. The cover
plate 52 of the detachable hinge 5 further has a transverse open
chamber 523 perpendicularly communicated with the longitudinally
extended -shaped open chamber 521 is suitable for use in a luggage
housing that is mounted with an extension shell 6. The connection
plate 51 is comprising two plates 510'. An open chamber 5101' is
formed after the two plates 510' assembled in order to let double
open end zipper 2 passed.
Embodiment III
[0031] Since the upper housing member 11 and the lower housing
member 13 are structurally detachable, an annular extension shell
(see FIG. 19) can be provided between the upper housing member 11
and the lower housing member 13 by connection of zipper 10 or by an
aluminum alloy strip 20 (see. 20) to increase the volume of the
luggage housing 1. The annular extension shell 6 (see FIG. 21)
comprises an annular shell body 61 fitting the configuration of the
rim of the upper housing member 11 or the lower housing member 13,
a second zipper tape 22 and a first zipper tape 21 respectively
stitched along two opposite sides of the annular shell body 61 and
detachably fastenable to the first zipper tape 21 at the lower
housing member 13 and the second zipper tape 22 at the upper
housing member 11 by the zipper sliders 25. Further, the thickness
(or so-called width) S of the annular extension shell 6 can be
variously configured to meet different requirements. One luggage
housing 1 can be equipped with multiple annular extension shells 6
of different thickness S for option. The extension shell 6 can be
made of a foldable flexible or hard material.
[0032] In the installation of the luggage housing, insert the pins
24 at the two ends of the second zipper tape 22 through the two
zipper sliders 25 into the respective boxes 23 at the two ends of
the first zipper tape 21 and simultaneously assemble the detachable
hinge 4 or 5 at the upper housing member 11 and the lower housing
member 13, then pull the two zipper sliders 25 upwardly or
downwardly to the opposing top and bottom sides of the luggage
housing 1, then fasten up the two detachable flexible buckles 3 to
secure the upper housing member 11 and the lower housing member 13
closely together. Thus, the luggage housing is assembled and
closed. Dismounting the luggage housing is achieved by performing
the aforesaid steps reversely. After separation of the upper
housing member 11 and the lower housing member 13, the upper
housing member 11 can be attached to the inside of the lower
housing member 13 for packaging, minimizing the volume and saving
the packing materials and costs. Further, because the upper housing
member 11 is received inside the lower housing member 13, the
package can bear high pressure, avoiding delivery damage.
[0033] Furthermore, the aforementioned extension shell can be
linked by the straight detachable hinge or by the T-shaped
detachable hinge.
[0034] Further, a N-shaped plastic strip 70 (see FIG. 9) can be
connected to the stitches between the upper and lower housing
members 11,13 and the second and first zipper tapes 22,21 to
prevent the zipper sliders from getting stuck.
[0035] In conclusion, the present invention can be summarized as
having the following enhancement effects:
1. The boxes 23 at the two side of two zipper sliders 25 of double
opened end zipper 2 and the pins 24 at the other side of the double
opened end zipper 2 enable the teeth of the zipper easily
positioned. Additional the detachable hinges 4,5 at the upper
housing member 11 and the lower housing member 13 enables easily
sealed, separated and assembled. 2. The upper housing member 11 and
the lower housing member 13 can be separated easily by dismounting
the first buckle member 31 and the second buckle member 32 and
disengaging the pins 24 at the second zipper tape 22 from the boxes
23 at the first zipper tape 21 and then removing the hinge axle 44
of the detachable hinge 4 from the axle housings 411 of the other
hinge plates 41. If the detachable flexible buckle 3 is used, the
user can manually unfasten the wing nut 55 and then remove the
screw bolt 54, enabling the upper and lower housing members 11,13
to be fully separated. 3. The upper housing member 11 and the lower
housing member 13 can be received together for packaging to reduce
the volume of the luggage. When the upper and lower housing members
of a plurality of luggage housings 1 are packaged and transported
together to the destination, the complete luggage housings 1 can be
quickly and manually assembled without any tools. This design
reduces luggage housing packaging and shipping costs. 4. When the
upper and lower housing members 11,13 are received and packed
together, the luggage housing 1 can bear high pressure during
transportation, avoiding deformation and damage. The arrangement of
the extension shell 6 between the upper and lower housing members
11,13 greatly increases the storage volume of the luggage housing
1. When the extension shell 6 is not used, it can be attached to
the inside wall of the luggage housing 1, facilitating
application.
