Description
FIELD OF THE INVENTION
[0001] The present invention relates generally to bags, and more
particularly to a shock-absorbing bag having air chambers for
protecting the storage item against impact.
BACKGROUND OF THE INVENTION
[0002] Regular bags for holding notebook computers or precision
instrument commonly have a shock absorbing or impact proof function
to absorb shocks and protect the storage item against impact.
According to conventional designs, foamed material, for example,
sponge is commonly used and installed in the secret compartments of
the gags to absorb shocks. The installation of the foamed material
complicates the fabrication of the bags. Furthermore, the foamed
material becomes aged quickly with use, lowering the shock
absorbing functioning of the bags.
SUMMARY OF THE INVENTION
[0003] It is the main object of the present invention to provide a
shock-absorbing bag, which has air chambers therein to provide a
sock-absorbing function and is easy to manufacture.
[0004] To achieve the object of the present invention, the
shock-absorbing bag is formed of a single piece of sheet member
that is folded up and sealed into a predetermined shape defining a
holding space for holding an object. The sheet member comprises a
first sheet layer, a second sheet layer sealed to the first sheet
layer, at least one air chamber defined in between the first sheet
layer and the second sheet layer, and an air valve provided at one
of the first sheet layer and the second sheet layer through which
air is driven into or forced out of the at least one air
chamber.

invention.
[0006] FIG. 2 is a sectional view taken along line 2-2 of FIG.
1.
[0007] FIG. 3 illustrates the outer appearance of a shock-absorbing
bag constructed according to the present invention.
[0008] FIG. 4 is a side view in section of the shock-absorbing bag
shown in FIG. 3.
[0009] FIG. 5 is a schematic drawing showing an alternate form of
the air chamber for the shock-absorbing bag according to the
present invention.
DETAILED DESCRIPTION OF THE INVENTION
[0010] Referring to FIGS. 1 and 2, a shock-absorbing bag 1 is
comprised of a single piece of sheet member 10. The single piece of
sheet member 10 is comprised of a first sheet layer 11 and a second
sheet layer 12. In actual fabrication, the first sheet layer 11 and
the second sheet layer 12 are respectively made of plastics, and
peripherally sealed together by a heat press. As shown in FIG. 1,
the connection area between the first sheet layer 11 and the second
sheet layer 12 forms a sealing part 13, and the other part of the
first sheet layer 11 and the second sheet layer 12 defines with the
sealing part 13 six air chambers 14 in air communication with one
another. A narrow air passage 141 is respectively provided between
each two adjacent air chambers 14 so that the air chambers 14 are
in air communication with one another and, maintained in an
airtight status isolated from the atmosphere. An air valve 15 is
installed in the first sheet layer 11 through which air is driven
into the air chambers 14.
[0011] Referring to FIG. 3 and FIG. 2 again, the sheet member 10,
as shown in FIG. 1, includes two side panels 101 and 102, a front
panel 103, a bottom panel 104, a back panel 105, and a top cover
panel 106. The panels 101-106 are folded up and fastened together,
forming the shock-absorbing bag 1 as shown on FIG. 3. When set into
shape, the panels 101-106 form the six sides of the shock-absorbing
bag 1 defining a holding space 107, and the air valve 15 is
disposed inside the holding space 107. The periphery of the panels
101-106, namely, the sealing part 13 of the single piece sheet
member 10 can be fastened up by stitches or a bonding agent.
[0012] Referring to FIG. 3 again, pockets 16 of different sizes are
respectively provided at the side panels 101 and 102 and the front
panel 103. A snap 17 is provided for enabling the top cover panel
106 to be detachably fastened to the front panel 103 to close the
holding space 107. Connectors 18 are fixedly provided at the side
panels 101 and 102 to hold a shoulder strap 19. The pockets 16, the
snap 17, and the connectors 18 can be fixedly fastened to the
second sheet layer 12 at an outer side by injection molding, EVA
heat press, or stitches before folding up the sheet member 10 into
shape. After the sheet member 10 was folded up and sealed to form
the shock-absorbing bag 1, the pockets 16, the snap 17, and the
connectors 18 are disposed on the outside of the shock-absorbing
bag 1.
[0013] Referring to FIG. 4 and FIG. 3 again, before the use of the
shock-absorbing bag 1, air is driven through the air valve 15 into
the air chambers 14. The user can adjust the inside air pressure of
the air chambers 14 as desired. When the user putted an object, for
example, a notebook computer NB in the holding space 107 of the
shock-absorbing bag 1 and closed the top cover panel 106, the
notebook computer NB is surrounded by the air chambers 14, i.e.,
the air chambers 14 support the notebook computer NB in place
against vibration and, protect the notebook computer NB against
impact. When not in use, the inside air is forced out of the air
chambers 14 through the air valve 15 to compact the shock-absorbing
bag 1, reducing space occupation.
[0014] FIG. 5 illustrates an alternate form of the air chambers.
According to this alternate form, a continuously curved sealing
line 13' is sealed to the air chamber 14' by a heat sealing
apparatus, separating the air chamber 14' into two independent
subsidiary air chambers 14a and 14b. Therefore, when one subsidiary
air chamber 14a or 14b damaged, the other subsidiary air chamber
14b is still maintained in function. In the same way, each air
chamber may be separated into three or more subsidiary air
chambers.
