Description
[0001] The present invention relates to a backpack with special
structure, and more particularly to a backpack which is capable of
changing the position of its center of gravity easily.
BACKGROUND OF THE INVENTION
[0002] Most modern people work all day in air conditioning rooms of
business or commercial buildings, which results in their lack of
exercises, and accordingly, results in their introspection or
resolution of wanting to do more exercises to keep healthy.
Therefore, various kinds of outdoor sports, which need long time
movement, such as mountain climbing, bicycle riding or etc, become
more popular. During the participation of doing these sports,
personal facilities, foods, or etc need to be carried on the back
of the sport participant when doing long time duration movements or
sporting activities. During the sporting activity, people need to
move upward or downward, and problems such as energy wasting,
energy saving or personal safety should be considered. According to
the research conducted by Liu and Chou in 2004, if the weight of
the backpack is substantially 10% the weight of the body, and the
moving rate is 6.4 km/hour, there will be a smaller psychological
load. According to the research by Stuempfle et al. conducted in
2004, the weight distribution of the goods in the backpack
influences walking load obviously. Principly, light articles are
preferred to be put at lower portion of the backpack and heavy
articles are preferred to be put at upper portion of the backpack.
Otherwise, the center of gravity of the backpack is preferred to be
close to the body, making large muscle groups of the body to be
bearing the load (Legg, 1985; Howe and Getchell, 1995).
[0003] The inventor of the present invention had done a research
about effects of gravity-centre-position on walking load under
slopes. The result of the aforementioned research is as follow: if
walking with a backpack of higher center of gravity on a slope of
6%, the oxygen consumption (VO2) is significantly increased, which
indicates that the results being obviously different from some
former or previous studies' results. Therefore, the aforementioned
research by the inventor suggests the following: if walking on
level or downhill path, the center of gravity of the backpack is
preferred to be maintained at a higher position, while if walking
on uphill path, the center of gravity of the backpack is preferred
to be maintained at a lower position.
[0004] As is known, the center of gravity of all every known
backpack are fixed whenever the goods or items are already filled
therein, and only if the goods or items are taken out of the
backpack and refilled or repacked in another particular different
way, would then be able to change the center of gravity of the
packed backpack. Therefore, there is not one backpack that is
capable of meeting our requirements for adjusting or changing the
preferred center of gravity positions at will or on the go.
[0005] Therefore, the capability to change the position of center
of gravity in a convenient and simple way, as well as under the
consideration of other problems possibly faced by climbers during
mountain climbing, such as over perspiration or life saving in
unexpected accident, are the issues that we discussed in the
present invention.
SUMMARY OF THE INVENTION
[0006] The present invention provides a backpack with special
structure, which could change the position of its gravity centre
during uphill, downhill or level movement in a convenient and
simple way, for decreasing oxygen consumption and preserve more
energy.
[0007] The present invention further provides a backpack with
special structure, which could supply water for preserving energy
or saving life when people are dehydrated due to mass exercises or
encounter unexpected crisis.
[0008] The backpack includes a strapping member and a base
structure. The strapping member has a first surface and a second
surface opposite to the first surface. At least two straps are
disposed on the first surface and at least one pivotal structure is
disposed on the second surface. The base structure includes a plate
member, at least one storing structure, and at least one containing
structure. The plate member is pivoted to the strapping member via
the pivotal structure and the plate member has a first surface and
a second surface opposite to the first surface. The first surface
of the plate member confronts the second surface of the strapping
member. The storing structure and the containing structure are
disposed on the second surface of the plate member. The containing
structure includes an upper containing structure and a lower
containing structure for accommodating fluid. A connecting
structure is connected between the upper containing structure and
the lower containing structure, and a stopper structure is disposed
on the connecting structure.
[0009] The backpack includes a strapping member and a base
structure. The strapping member has a first surface and a second
surface opposite to the first surface. At least two straps are
disposed on the first surface. At least one pivotal structure and
at least one containing structure are disposed on the second

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0014] The present invention will now be described more
specifically with reference to the following embodiments. It is to
be noted that the following descriptions of preferred embodiments
of this invention are presented herein for purpose of illustration
and description only. It is not intended to be exhaustive or to be
limited to the precise form disclosed.
[0015] FIG. 1 is a schematic, three-dimensional view of a backpack
according to a first embodiment of the present invention. Referring
to FIG. 1, the backpack includes a strapping member 10 and a base
structure 20.
[0016] The strapping member 10 has a first surface and a second
surface opposite to the first surface. At least two straps 12, 13
are disposed on the first surface of the strapping member 10, and
at least one pivotal structure 14 is disposed on the second surface
of the strapping member 10. In this illustrated first embodiment,
the pivotal structure 14 is a column perpendicularly extending from
the second surface of the strapping member 10. The column of the
pivotal structure 14 has a flange at a free end thereof for
engaging in a slot defined in the base structure 20. The pivotal
structure 14 may also includes a shaft with outer threads formed at
a free end thereof and a nut with inner threads formed therein.
[0017] The base structure 20 includes a plate member 21, at least
one storing structure 22, and at least one containing structure 23.
The plate member 21 is pivoted to the strapping member 10 via the
pivotal structure 14. More concretely, the plate member 21 defines
the slot that is corresponding to the column of the pivotal
structure 14, or a through hole corresponding to the shaft of the
pivotal structure 14. In order to pivotably connect the plate
member 21 to the strapping member 10, the column of the pivotal
structure 14 needs to be engaged in the slot of the plate member 21
of the base structure 20 or the shaft of the pivotal structure 14
needs to pass through the through hole of the plate member 21 and
the nut of the pivotal structure 14 needs to be screwed on the
shaft thereof to keep the plate member 21 on the strapping member
10. The plate member 21 has a first surface and a second surface
opposite to the first surface. The first surface of the plate
member 21 confronts the second surface of the strapping member 10.
The storing structure 22 and the containing structure 23 are
disposed on the second surface of the plate member 21. The storing
structure 22 includes a first storing structure 221 and a second
storing structure 222. The first storing structure 221 and the
second storing structure 222 are disposed at opposite sides of the
second surface of the plate member 21. The storing structure 22 is
used for storing goods, especially solid goods. The containing
structure 23 is disposed between the first storing structure 221
and the second storing structure 222, and extends in vertical
direction. The containing structure 23 includes a first containing
structure 231 and a second containing structure 232. The first
containing structure 231 is disposed at an upper portion of the
plate member 21 while the second containing structure 232 is
disposed at a lower portion of the plate member 21. A connecting
structure 233 is disposed between the first containing structure
231 and the second containing structure 232, and a stopper
structure 234 is disposed on the connecting structure 233. In the
first embodiment, the connecting structure 233 is a pipe connecting
the first containing structure 231 with the second containing
structure 232 and the stopper structure 234 is a valve disposed on
the connecting structure 233 being of pipe in shape.
[0018] The first containing structure 231 and the second containing
structure 232 are used for accommodating fluids. If the center of
gravity is required to be positioned at the upper portion of the
backpack, the fluid is accommodated in the first containing
structure 231. If the center of gravity is required to position at
the lower portion of the backpack, the stopper structure 234 needs
be turned on and then turned off, making or allowing the fluid in
the first containing structure 231 flowing into the second
containing structure 232, and the center of gravity is accordingly
changed to the lower portion of the backpack from the upper portion
of the backpack. If the center of gravity is required to go back to
the upper portion of the backpack, the base structure 20 needs to
be rotated in bottom-to-top manner, and the center of gravity is
therefore changed back to the upper portion of the backpack.
[0019] FIG. 2 is a schematic, three-dimensional view of a backpack
according to a second embodiment of the present invention.
Referring to FIG. 2, the backpack includes a strapping member 10'
and a base structure 20'.

[0022] The first upper container 231' and the first lower container
232' are used for accommodating fluids. If the center of gravity is
required to position at the upper portion of the backpack, the
fluid is accommodated in the first upper container 231'. If the
center of gravity is required to position at the lower portion of
the backpack, the stopper structure 234' needs be turned on and
then turned off, making the fluid in the first upper container 231'
flowing into the first lower container 232', and the center of
gravity is accordingly changed to the lower portion of the backpack
from the upper portion of the backpack. If the center gravity is
required to go back to the upper portion of the backpack, the base
structure 20' needs to be rotated in bottom-to-top manner, and the
center of gravity is therefore changed back to the upper portion of
the backpack. The function and operation manner of the second upper
container 235' and the second lower container 238' are the same as
the first upper container 231' and the first lower container 232',
redundant details are not repeated here.

231''. If the center of gravity is required to be positioned at the
lower portion of the backpack, the stopper structure 234'' needs be
turned on and then turned off, making the fluid in the first upper
container 231'' flowing into the first lower container 232'', and
the center of gravity of the backpack is accordingly changed to the
lower portion of the backpack from the upper portion of the
backpack. If the center of gravity is required to go back to the
upper portion of the backpack, the base structure 20'' needs to be
rotated in bottom-to-top manner, and the center of gravity is
therefore changed back to the upper portion of the backpack. The
function and operation manner of the second upper container 235''
and the second lower container 238'' are the same as the first
upper container 231'' and the first lower container 232'',
redundant details are not repeated here.
[0027] For the forgoing descriptions, the backpack with special
structure is a kind of backpack whose gravity-centre-position could
be changed easily. Due to different gravity-centre-positions are
preferred during uphill and downhill movement, climbers could
change the position of center of gravity of the backpack according
to landform or landscape and unneeded expenditure of energy is
accordingly saved. Furthermore, due to the fluid contained in the
containing structure being drinking water, climbers can drink the
water contained in the containing structure if they have consumed
or exhausted the water carried by hand. The water in the containing
structure can also be used to save life in an unexpected crisis.
That is, the present invention utilizes the fluidity of the fluid
contained in the containing structure to change the position of the
center of gravity of the backpack in an easy way. If the fluid is
drinking water, it can also be used to quench thirst or save life
in an unexpected crisis. These all makes the backpack of the
present invention be a kind of one-stone-two-birds product.
[0028] While the invention has been described in terms of what is
presently considered to be the most practical and preferred
embodiments, it is to be understood that the invention needs not be
limited to the disclosed embodiment. On the contrary, it is
intended to cover various modifications and similar arrangements
included within the spirit and scope of the appended claims which
are to be accorded with the broadest interpretation so as to
encompass all such modifications and similar structures.
