Background and Summary of the Invention
[0001] This invention relates to storage and carrying devices such as backpacks, sacks,
and packs. More particularly, the invention relates to a pack or sack with an angled
opening.
[0002] The invention will be explained in conjunction with packs and sacks such as backpacks
and packs which can be carried by one or more handles. However, it will be understood
that the invention can be used with other types of devices for storing and carrying
articles.
[0003] A backpack conventionally includes a plurality of panels which are stitched or otherwise
secured together. The panels form an interior storage compartment, and access to the
compartment is provided by a zipper or the like. The zipper is conventionally located
where two panels meet or in the top of the pack. However, when the zipper is open,
a portion of the pack becomes unsupported and may droop or sag, or the opening might
remain substantially closed and interfere with loading or unloading the pack.
[0004] The invention provides a pack with an angled opening which angles upwardly and rearwardly
from the front of the pack. The ends of the opening are positioned between the bottom
and the top of the sack, preferably about 1/4 to 1/2 of the distance from the bottom
to the top. The Opening is closed by a zipper or other fastener. When the opening
is unfastened, the back portion of the pack is not completely detached from the front
portion, and the back portion is thereby supported and prevented from substantially
sagging or drooping. However, the back portion separates from the front of the pack
sufficiently to allow access to the interior compartment.
Description of the Drawing
[0005] The invention will be explained in conjunction with an illustrative embodiment showing
the accompanying drawings, in which --

with a pair of interior compartments, the openings in the pack being shown in an open
condition;

Figure 4 is a side elevational view of the backpack of Figure 3.
Description of Specific Embodiment
[0006] A pack 10 includes a front portion 11, a back portion 12, and an intermediate portion
13. The particular pack illustrated includes a pair of shoulder straps 14 which are
attached to the front portion and a handle 15 which is attached to the top of the
side portion.
[0007] A user can carry the pack on his back by inserting his arms through the shoulder
straps, or he can carry the pack by the handle. The front portion 11 lies against
the back of the user when the pack is carried by the user and faces forwardly. The
back portion 12 faces rearwardly.
[0008] The front portion 11 is formed by a substantially flat panel which includes a curved
top edge 17, a bottom edge 18, and a pair of side edges 19. For a soft pack, the panel
can be made of flexible fabric such as woven nylon. The woven fabric provides some
stiffness to the panel, and the panel can be further reinforced with padding or other
stiffening material if desired.
[0009] The back portion 12 is also formed by a substantially flat panel which includes a
curved top edge 21, a bottom edge 22, and a pair of side edges 23. The back panel
may also advantageously be formed from relatively flexible fabric with some stiffness
such as a woven nylon.
[0010] The intermediate portion 14 extends between the front and back panels and spaces
the front and back panels apart to form an interior compartment 25 within the pack.
The intermediate portion includes an arched top portion 26 and a substantially flat
bottom portion 27 which extend between the top and bottom edges of the front and back
portions and a pair of side portions 28 which extend between the side edges of the
front and back portions.
[0011] The intermediate portion may also be formed from relatively flexible fabric such
as woven nylon. The front, back, and intermediate portions are formed separately and
are secured together by stitching along their adjacent edges, which forms seams in
the pack. The handle 15 is stitched to the arched top portion of the intermediate
portion.
[0012] An opening or slit 30 is formed in the intermediate portion 13 for providing access
to the interior compartment. The opening includes a pair of ends 31 which are adjacent
the front portion 11 and a U-shaped central portion 32 which angles upwardly and rearwardly
toward the top of the pack. In the embodiment illustrated, both of the upper and lower
edges 33 and 34 of the opening lie entirely within the intermediate portion 13 between
the seams which attach the intermediate portion to the front and back portions.
[0013] The opening may be closed by a zipper 35. However, qother fastening or closing means
could be used. In the embodiment illustrated, the top of the intermediate portion
forms which extends beyond the upper row 37 of Zipper teeth for covering the zipper
when the opening is closed as shown in Figures 3 and 4.
[0014] The ends 31 of the opening are located at about 1/2 of the distance between the bottom
and top of the front portion 11. As a result, when the zipper is open as shown in
Figures 1 and 2, the portions of the intermediate and front portions below the opening
remain connected to the lower portion of the front portion and are supported thereby.
The front portion is reinforced not only by the padding or other stiffening material
but also by the arched top portion 26. The material below the bottom edge 34 of the
opening tends to hold its shape rather than collapse because of the tightness of the
weave and the arched shape of the edge 34.
[0015] Even though the opening does not extend all the way to the bottom of the pack, the
upward and rearward angle of the opening allows the pack to open sufficiently to provide
convenient access to the interior compartment as shown in Figure 2. The lower edge
34 of the opening drops away from the upper edge 33 of the opening sufficiently to
allow the user to insert his hand through the opening in a generally downwardly direction.
[0016] The ends of the opening are preferably located above the bottom of the pack so that
the bottom of the front panel supports the open portion of the pack when the zipper
is open. The ends are preferably within a range of about 1/4 to 3/4 of the distance
from the bottom of the pack to the top of the pack.
[0017] The opening angles upwardly to form an included angle A with the front panel 11 (Figure
4). The angle A is preferably within the range of about 10° to 60°. In the embodiment
illustrated the angle A is about 45°.
[0018] An auxiliary compartment 40 is provided by a pair of panels 41 and 42 which are attached
to the back panel 12. The panels 41 and 42 are separately along a U-shaped opening
43 which angles upwardly and rearwardly at an angle B of about 10° to 15° relative
to the back panel 12.
[0019] The panel 41 includes a pair of side edges 44 and a curved top edge 45 which are
stitched to the back panel 12. The panel 42 includes a bottom edge 46 and a pair of
short side edges 47 which are stitched to the back panel. The panels can also be formed
from woven nylon fabric.
[0020] The opening 43 is closed by a zipper 49 and upper and lower rows of zipper teeth
50 and 51. The upper zipper teeth 50 are positioned inside of the curved edge 52 of
the panel 41 to provide a flap which covers the opening when the opening is closed.
[0021] The panel 42 includes a relatively flat central portion 53 which forms the back of
the auxiliary compartment, a forwardly extending bottom portion 54, and a pair of
forwardly extending side portions 55. The front portion of the auxiliary compartment
is formed by the back panel 12. The intermediate portion of the compartment is formed
by the panel 41 and the bottom and side portions of the panel 42.
[0022] The ends of the opening 43 where the two rows of Zipper teeth meet is located about
1/4 of the distance between the bottom 54 of the compartment and the top of the panel
41. When the Zipper 49 is open as illustrated in Figure 2, the panel 42 is supported
by the attachment of the side portions 55 to the panel 12 and by the arched shape
of the panel which is provided by the central portion 53 and the side portions 55.
However, the angle of the opening allows the upper edge of the panel 42 to move away
from the panel 41 to allow access to the compartment.
