AN IMPROVED BACKPACK
BACKGROUND OF THE INVENTION
The present invention relates to an improved backpack and, in
particular, to a backpack adapted to store therewithin the components of a
tent
in a manner that is space saving, less prone to theft of the tent components,
and improves the structure and function of the backpack.
Backpacks have become one of the most widespread and popular forms
of portable carrying devices in recent decades. However, conventional
backpacks are ill-suited to storing therewithin the components of a tent. The
fastening of tent components to the exterior of a backpack is normally
cumbersome to the backpack wearer, and the tent components, if not the
entire backpack, are prone to theft arising from the visibility and allure of
the
tent components.
Furthermore, the proliferation of backpacks generally has given rise to a
specialization of their structure and function to suit particular niche
markets.
Their popularity, particularly in the niche market of school carry packs, has
brought with it a demand for greater versatility, as users seek a "one pack
suits
all" backpack that can be used for a variety of purposes, such as for
schooling,
walking/trekking and camping purposes.
In many cases, backpacks suited for school use are ill suited for other
purposes. For instance, school carry packs lack the necessary adjustability,
strength, and storage capacity required for walking/trekking and camping
purposes. On the other hand, backpacks suited for walking/trekking and
camping purposes are often iil suited far school use. The need for greater
versatility of structure and function of backpacks is addressed in the present
specification.

DETAILED DESCRIPTION OF THE INVENTION
The backpack 10 shown in the Figures is fabricated of a strong, water
protective, sheet material normally used to make backpacks. The backpack 10
includes storage means in the form of numerous compartments openable and
closable by zip-fastener arrangements. There is a rearmost compartment for
storing a harness and support arrangement which is accessible by a pair of
slidable zip runners 14, 16 engaging the interlocking teeth of a zip-fastener
track 18 set along the two opposing edges which define the opening to the
rearmost compartment. The runners 14, 16 can be pulled in opposite
CA 02442226 2003-09-26
directions to separate the two edges, thereby peeling away the rear flap 20 so
as to open the rearmost compartment.
Secured within the rearmost compartment is a harness means
comprising a pair of padded shoulder straps 22, 24, a padded waist strap 26,
5 (shown unbuckled), and a tightening belt and buckle arrangement 28 which
can be tightened across the chest of the person. There is also a lumbar
support pad 30. The rear flap 20, in rolled-up form, is stored in a small
compartment 31 at the top of the backpack 10.
The padded shoulder straps 22, 24 are joined by a support portion 32 to
which is attached a pair of slidable anchor pieces (not shown). Each anchor
piece is able to slide up and down a respective one of a pair of symmetrically
disposed track members 36, 37 secured firmly to the backpack 10. As a
consequence, the shoulder straps 22, 24 can have their height adjusted
relative to the remainder of the backpack 10. Where the shoulder straps 22,
24 are low (as shown in Fig 2), the support portion 32 is prevented from
sliding
upwardly (as is likely to occur as a result of movement during wearing) by a
locating belt and buckle arrangement. Adjusting the position of the shoulder
straps 22, 24 along the track members 36, 37 allows the backpack 10 to be
worn at different height positions on the back of the person in accordance
with
that person's comfort preference. A low backpack height position will be the
result of wearing the backpack, as adjusted, shown in Fig 3, where the
shoulder straps 22, 24 are at their highest location along the track members
36, 37. A high backpack height position will be the result of wearing the
backpack, as adjusted, shown in Fig 2.
As shown in Fig. 3, the lumbar support pad 30, which is stitched or
otherwise foldably secured along its bottom edge to the base of the backpack
10, is folded down to provide a cushioned seat for the user. The lumbar
CA 02442226 2003-09-26
6
support pad 30 is normally fastened in an upright position against the
backpack
by a pair of first hook and loop type strips 31 on the inside surface of the
pad 30 engaging a pair of second hook and loop type strips 33 on the
intermediate connecting portion of the waist straps 26. The extent to which
the
5 pad 30 can be folded down may be determined by a pair of buckled straps 35,
37. The cushioned seat provided by the folded down pad 30 may be useful for
relaxation, and its location at the base of the backpack 10 enables the seated
user to use the upright main body portion of the backpack 30 as a back rest.
The straps 35, 37 inhibit the upright main body portion from falling down when
10 back pressure is applied by the pad seated user against it.
The articulated tent pole member 40 shown in Fig 4 is known in the art,
and two of the pole members 40 are used in assembling the tent shown in Fig
7. Each pole member 40 has seven pole portions 42 connected by six joint
assembles 44. Each joint assembly 44 comprises a hollow tubular member 46
extending from the end of one of the pole portions 42, and a spring action
cord
48, one end of which is secured to a fastening point inside the tubular member
46 and the other end of which is secured to the free end of the adjacent pole
portion 42, such that alignment of the two pole portions 42 will cause the
free
end to be drawn into the tubular member 46 by the natural tendency of the
Cord 48 to contract. '
The tent pole member 40, by virtue of its articulated structure, can be
folded into a compact form 49 and inserted into an elongated, upright pocket
50 as shown in Fig 5. Because the tent to be assembled requires two tent pole
members 40, there are two upright pockets 50 and they are located inside a
central compartment 52 of the backpack 10 against a wall nearest the rearmost
compartment and are symmetrically disposed across an upright axis of the
backpack. When a tent pole member in compact form 49 is stored in each of
CA 02442226 2003-09-26
7
the upright pockets 50, a rigid backbone structure is formed that strengthens
the backpack 10 against distortion. Each upright pocket 50 is closed by a top
flap 54 utilizing a hook and loop type fastening means.
The folded tent canopy and floor sheet 55, shown in Fig 6 being
released from its stored position in a base pocket 56 of the backpack 10, is
known in the art, and is used in assembling the tent 64 shown in Fig 7. The
base pocket 56 is openable and closable by a zip-fastener arrangement and,
when it stores the folded tent canopy and floor sheet 55, it provides a
reinforced and cushioned base to the backpack 10. The folded and stored tent .
canopy and floor sheet 55 is thus protected from physical damage and external
conditions, and is less prone to theft, by its protected and invisible storage
position inside the backpack 10. These benefits also apply to the stored tent
pole members 40 by virtue of their storage position inside the backpack 10.
There are a pair of female clasping members 70, 72 secured to the inside of
the base pocket 56 which are used to releasably fasten the backpack 10 to the
tent canopy and base sheet 55 which has corresponding male clasping
members 74, 76 (see also Fig. 7). The fastening means may, alternatively, be
a press-stud arrangement, a zip-fastener arrangement or the like.
After the tent canopy and floor sheet 55 has been released from within
the backpack 10 and unfolded, and the tent pole members 40 have similarly
been removed and unfolded, the tent structure 64 shown in Fig 7 may be
assembled. The male clasping members 74, 76 also provide a readily
identifiable reference position to facilitate the correct order of folding of
the tent
canopy and floor sheet 55 within the base pocket 56.
Various modifications may be made in details of design and construction
without departing from the scope and ambit of the invention.
