Description
TECHNICAL FIELD OF THE INVENTION
[0001] The present invention is related to a storage bag for
accommodating articles and particularly an expanding-folding
apparatus for storage bag to be easily expanded or folded with
multiple applications.
DESCRIPTION OF THE PRIOR ART
[0002] Currently the foldable storage boxes of the prior art
already exist in many variety based on the principle of volume
reduction for convenient storage. For instance, some existing
designs use flexible textile to constitute a box in a
three-dimensional rectangle shape with an upper horizontal bar
positioned at each of four sides of an upper surface, a bottom
horizontal bar positioned at each of four sides of a bottom surface
and a vertical bar positioned at each of four vertical sides. A
proper clearance is kept between the ends of the adjacent upper
horizontal bars and the bottom horizontal bars as well as the ends
of the vertical bars and the ends of both upper and bottom
horizontal bars. Each vertical surface of the box is further
provided with multiple folding lines in diagonal direction across
each other. Whereby the prescribed apparatus enables the box made
of flexible textile to constitute a storage space to accommodate
articles with the vertical bars and both upper and bottom
horizontal bars as well as to be twisted for folding into a flat
object.
[0003] Some revised boxes are provided with a cover and its each
corner is supported by a vertical truss provided at each corner of
a revised box.
[0004] However the storage boxes of the prior art is not convenient
in operation because of relatively large number in element quantity
and more complexity in structure. Further the problem of missing an
element can happen easily as well as the relatively higher cost of
manufacture.
SUMMARY OF THE INVENTION
[0005] An objective of the present invention is to provide a
storage bag that can be freely expanded or folded with simplicity
in structure and convenience in operation so as to reduce the
manufacture cost and create the maximum storage space and the
storage bag can be easily carried.
[0006] The expanding-folding storage bag of the present invention
is characterized in having a frame structure and a bag that the bag
is connected to a bottom of the frame structure and the frame
structure can be folded so as to close the bag at the same time.
Thereby the storage bag can be both used as a carrying bag by
itself and expanded into a storage space for accommodating articles
at the same time when the frame structure is expanded.
[0007] Therefore the technical means of the present invention
includes a frame structure and a bag that the frame structure
further includes a first frame and a second frame both in H shape,
two free ends of the first frame being movably connected to two
correspondent free ends of the second frame so as to fold both the
first frame and second frame toward each other into a overlapping
state. The bag is made of flexible material and has an opening
positioned at upper end with a circumference of the opening
connected to a bottom of the first and second frames.
[0008] A technical means of the expanding-folding frame structure
of the present invention can be embodied by bending a hallow tube
of rectangle cross-section into the first and the second frames and
the two free ends of the first frame are pivotally connected with
each end of two linkages whose two other ends are pivotally
connected with the two correspondent free ends of the second frame.
Thereby the first frame and the second frame can be folded toward
each other into an overlapping state.
[0009] The other technical means of the expanding-folding frame
structure of the present invention can be embodied by bending a
hallow tube of circular cross-section into the first and second
frames and a hinge is provided between each of the two free ends of
the first frame and correspondent each of the two free ends of the
second frame. Thereby the first frame and the second frame can be
folded toward each other into an overlapping state.
[0010] One other technical means of the expanding-folding frame
structure of the present invention can be embodied by bending a
solid tube into the first and second frames and the two free ends
of the first frame are pivotally connected to the two correspondent
free ends of the second frame. Thereby the first frame and the
second frame can be folded toward each other into an overlapping
state.
[0011] Based on a value-added consideration to facilitate the
operation, the present invention can be provided with a carrying
belt at the diagonal locations at each of the first and the second
frames. Thereby it only needs to lift up the carrying belt in order
to fold the first and the second frames toward each other into an
overlapping state and close the bag from the expanded state at the
same time. The carrying belt can provide an user to carry the
storage bag at folded state as a back-bag.
[0012] The first and second frames of the present invention can be
manufactured with either bamboo, wood, metal or other suitable
material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0025] Firstly as shown in FIG. 3, the preferred embodiment of the
present invention includes a frame structure 1 and a bag 2 that the
bag 2 is made of flexible material (such as textile or fiber-cloth)
and has an opening positioned at upper end with a circumference of
the opening to be connected to a bottom of the frame structure 1 so
as to constitute a storage bag.
[0026] There are multiple means to embody the frame structure 1 for
connecting with the bag 2 of the present invention. The embodiment
shown in FIG. 1 and FIG. 1A includes a first frame 11 and a second
frame 12 that are manufactured with hallow tube of rectangle
cross-section by bending into .PI. shape. A linkage 13 is provided
between each of two correspondent free ends of the frame 11 and
frame 12 in order to constitute a movable connection with the
pivots 14 that the linkage 13 is a bar at proper length, which is
approximate the height of the first frame 11 and the second frame
12 together, so as to fold the first frame 11 and the second frame
12 toward each other into an overlapping state (as shown in FIG. 2)
after being movably connected with the first frame 11 and the
second frame 12.
[0027] After the frame structure 1 of FIG. 1 connected with the bag
2, the opening of the bag 2 is open at the same time when the first
frame 11 and the second frame 12 are expanded such that an user can
put in or take out an article through the opening of the bag 2 (as
shown in FIG. 3). After usage, the user only needs to fold the
first frame 11 and the second frame 12 of the frame structure 1
toward each other in order to close the opening of the bag 2 at the
same time (as shown in FIG. 4).
[0028] FIG. 5 depicts the second preferred embodiment of the
present invention that the frame structure 1A includes a first
frame 11A and a second frame 12A that are manufactured with hallow
tube of circular cross-section by bending into .PI. shape. A hinge
15 is provided between each of two correspondent free ends of the
first frame 11A and the second frame 12A (as shown in FIG. 6). The
hinge 15 includes two end-plates and a two-bar device of pivotally
connection provided between the end-plates such that the two
end-plates are secured within the circular cross-section tubes of
the first frame 11A and the second frame 12A respectively while
only the two-bar device is positioned outside the circular
cross-section tubes so as to fold the first frame 11A and the
second frame 12A toward each other into an overlapping state (as
shown in FIG. 6). The detail structure of the hinge 15 is omitted
because it is a mechanical element of the prior art, not a
technical characteristic of the present invention.
[0029] After the frame structure 1A of FIG. 5 connected with the
bag 2, the opening of the bag 2 is open at the same time when the
first frame 11A and the second frame 12A are expanded such that an
user can put in or take out an article through the opening of the
bag 2 (as shown in FIG. 7). After usage, the user only needs to
fold the first frame 11A and the second frame 12A of the frame
structure 1A toward each other in order to close the opening of the
bag 2 at the same time (as shown in FIG. 8).
[0030] FIG. 9 depicts the third preferred embodiment of the present
invention that the frame structure 1B includes a first frame 11B
and a second frame 12B that are manufactured with solid tube by
bending into .PI. shape. The two free ends of the first frame 11B
are pivotally connected to the two correspondent free ends of the
second frame 12B so as to fold the first frame 11B and the second
frame 12B toward each other into a overlapping state (as shown in
FIG. 10). As shown in the embodiment of FIG. 9, the transverse
portions of both the first frame 11B and second frame 12B are
further made in a curvature so as to constitute the frame structure
1B in a different appearance than the previous embodiments.
[0031] After the frame structure 1B of FIG. 9 connected with the
bag 2, the opening of the bag 2 is open at the same time when the
first frame 11B and the second frame 12B are expanded such that an
user can put in or take out an article through the opening of the
bag 2. After usage, the user only needs to fold the first frame 11B
and the second frame 12B of the frame structure 1B toward each
other in order to close the opening of the bag 2 at the same time
(as shown in FIG. 10).
[0032] The embodiment of FIG. 11 is to further facilitate the
operation via a value-added consideration for the present
invention. A carrying belt 3 is provided at the diagonal locations
at each of the first frame 11 and the second frame 12 of the
aforesaid frame structure 1. Thereby the carrying belt 3 is across
the opening of the bag 2 without interference to an article being
either put in or taken out by the user when the storage bag is at
the expanded state. After usage, the user only needs to lift up the
carrying belt 3 so as to fold the first frame 11 and the second
frame 12 toward each other and close the bag 2 the same time (as
shown in FIG. 11).
