description provides a convenient illustration for implementing
exemplary embodiments of the invention. Various changes to the
described embodiments may be made in the function and arrangement
of the elements described without departing from the scope of the
invention as set forth in the appended claims.
[0027] Referring to FIG. 1, a folding collapsible bag in accordance
with the present invention comprises a support frame structure,
which comprises a first base member 1A, a second base member 1B, a
first supporting element 2A and a second supporting element 2B.
[0028] The first base member 1A and the second base member 1B are
flat plate members made from a tough and hard material. The first
base member 1A and the second base member 1B are horizontally
arranged on the bottom side and kept apart for supporting the
bottom side of the folding collapsible bag in shape. The first
supporting element 2A and the second supporting element 2B are
respectively prepared from a resilient wire rod and bent into a
substantially arched shape. Further, the first supporting element
2A and the second supporting element 2B are respectively arranged
above the first base member 1A and the second base member 1B.
[0029] FIG. 2 illustrates an alternate form of the support frame,
in which the first base member 1C and the second base member 1D are
respectively prepared from a resilient wire rod and bent into a
substantially arched shape.
[0030] Referring to FIG. 3, the folding collapsible bag further
comprises a bag body 3 made from a soft fabric or any suitable
flexible sheet material. The bag body 3 can be configured subject
to any desired shape, having an opening on the top side. The first
base member 1A or 1C and the second base member 1B or 1D are set in
and affixed to the bag body 3 to stretch the bottom panel of the
bag body 3 into a planar shape. The first supporting element 2A and
the second supporting element 2B are bilaterally obliquely set in
and affixed to the bag body 3 to stretch the periphery of the bag
body 3 into shape, keeping the top open side of the bag body 3
opened. When turning the first base member 1A or 1C toward the
first supporting element 2A and the second base member 1B or 1D
toward the second supporting element 2B, the folding collapsible
bag is collapsed into a flat condition (see FIGS. 4 and 5).
Further, a first fastening member 3A and a second fastening member
3B are fixedly mounted in the bag body 3 at two opposite sides.
When the folding collapsible bag is collapsed, the first fastening
member 3A and the second fastening member 3B are fastened together
to hold the folding collapsible bag in the collapsed shape.
Further, the first fastening member 3A can be a strip of hook
material (or a strip of loop material), and the second fastening
member 3B can be a strip of loop material (or a strip of hook
material) fastenable to the first fastening member 3A.
Alternatively, the first fastening member 3A and the second
fastening member 3B can be made fastenable to each other by means
of magnetic attraction.
[0031] FIG. 6 illustrates another alternate form of the support
frame, in which an extra supporting element, i.e., the third
supporting element 2C is set in between the first supporting
element 2A and the second supporting element 2B. Similar to the
first supporting element 2A and the second supporting element 2B,
the third supporting element 2C is prepared from a resilient wire
rod and bent into a substantially arched shape. According to this
alternate form, the first base member 1A and the second base member
1B are flat plate members made from a tough and hard material,
however the first base member 1C and the second base member 1D that
are respectively prepared from a resilient wire rod and bent into a
substantially arched shape, as shown in FIG. 2, can be used as
substitutes.
[0032] Referring to FIG. 7 and FIG. 6 again, the first base member
1A or 1C and the second base member 1B or 1D are set in the bag
body 3 to stretch the bottom panel of the bag body 3 into a planar
shape; the first supporting element 2A and the second supporting
element 2B are bilaterally obliquely set in the bag body 3 to
stretch the periphery of the bag body 3 into shape, keeping the top
open side of the bag body 3 opened; the third supporting element 2C
is vertically set in the baby body 3 on the middle between the
first supporting element 2A and the second supporting element 2B to
stretch the middle part of the bag body 3 into shape. Further, a
board member 32 can be affixed to the third supporting element 2C
to divide the inside space of the bag body 3 into two compartments.
Further, two first fastening members 3A are affixed to the inside
of the bag body 3 at two opposite sides, and two second fastening
member 3B are respectively fixedly provided at two opposite sides
of the board member 32. When not in use, turn the first base member
1A or 1C toward the first supporting element 2A and the second base
member 1B or 1D toward the second supporting element 2B, and then
turn the first supporting element 2A and the second supporting
element 2B toward the third supporting element 2C, thus the folding
collapsible bag is collapsed into a flat condition (see FIGS. 8 and
9). When the folding collapsible bag is collapsed, the first
fastening members 3A and the second fastening members 3B are
respectively fastened together to hold the folding collapsible bag
in the collapsed shape. Further, a cord handle 31 is provided at
the top side of the third supporting element 2C so that the user
can lift the cord handle 31 and then collapse the bag
conveniently.
[0033] FIG. 10 is a perspective view of another alternate form of
the folding collapsible bag in accordance with the present
invention. According to this embodiment, the support frame
structure further comprises a third supporting element 2C and a
fourth supporting element 2D set in between the first supporting
element 2A and the second supporting element 2B in a parallel
manner. Further, the third supporting element 2C and the fourth
supporting element 2D are respectively mounted with a board member
32 so that these two board members 32 divide the inside space of
the bag body 3 into three compartments. Further, two first
fastening members 3A are respectively affixed to the inside of the
bag body 3 at two opposite sides, and two second fastening members
3B are respectively affixed to the board members 32 at the third
supporting element 2C and fourth supporting element 2D for the
fastening of the two first fastening members 3A respectively to
secure the folding collapsible bag in the collapsed status.
[0034] It will be understood that each of the elements described
above, or two or more together may also find a useful application
in other types of methods differing from the type described
above.
[0035] While certain novel features of this invention have been
shown and described and are pointed out in the annexed claim, it is
not intended to be limited to the details above, since it will be
understood that various omissions, modifications, substitutions and
changes in the forms and details of the device illustrated and in
its operation can be made by those skilled in the art without
departing in any way from the spirit of the present invention.
