Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to backpacks, and more particularly
to a lightweight ergonomic backpack harness that anatomically
distributes a portion of the load from the shoulders to the waist
region of a user.
[0003] 2. Description of the Related Art
[0004] Overloaded backpack usage is one of the most damaging
injuries to the spine and the posture of a user frequently
diagnosed by chiropractors and physicians alike. Backpacks have a
myriad of different implementations and are typically used by
various people, including, for example, students, military, hikers,
and the like for carrying and transporting various items.
[0005] Conventionally, backpacks include an internally reinforced
structure that is built into the lining of the backpack. A typical
backpack includes shoulder straps which hook over the shoulders and
a flat portion of the backpack lies flat up against the back of the
user.
[0006] In use, the entire load from the backpack is directed
vertically through the shoulder straps onto the shoulders of the
user. The narrow construction of a shoulder strap creates a point
stress at each shoulder strap on the user which can cause severe
discomfort when the backpack is normally loaded. As a result of a
heavily weighted backpack, the user attempts to compensate for the
additional load by straining and irregularly contorting their back
to lean forward with poor posturing. Various disadvantages have
been deduced as a result of the unruly stress on the shoulders.
Generally, a user will unnaturally hunch forward to overcompensate
for the excessive load on the shoulders thereby subjecting
themselves to ill posture and potentially bad back problems.
Numerous painful consequences stem from the over-weight backpack
including, head and neck aches, muscle spasms, and poor blood
circulation to the arms and hands of the user resulting from blood
constriction of the straps and the loaded backpack.
[0007] It is clear that this problem has not been solved and there
is still a longstanding need for an adjustable backpack load
carrying system that is ergonomic, lightweight, yet strong and
simple in construction that promotes proper anatomic posture and
healthy back alignment positioning while in use.
SUMMARY OF THE INVENTION
[0008] The present invention addresses the shortcomings identified
in providing an adjustable anatomic backpack load carrying
system.
[0009] The backpack load carrying system includes a pair of
shoulder straps, a waist belt, and a back pad. The suspension
system should be adjustable to accommodate various torso shapes and
should comfortably support the load on the backpacker. The backpack
load carrying system includes a securing mechanism adapted to
secure the backpack load carrying system to a backpack.
[0010] The backpack load carrying system is configured so that an
angle between a backpack support frame and a waist support frame is
provided to distribute the weight of the load in the backpack from
being directly applied vertically to the shoulders through the
shoulder straps and distributing a portion of the load to the waist
support and onto the hips and lower back, promoting a natural
upright standing position thereby enhancing the body's natural
ability to properly carry weight. The backpack load carrying system
reduces stress on the body by redistributing the weight from the
shoulders to the hips and waist, and substantially lightens the
effective load felt by the user.
[0011] The backpack load carrying system props the user's backpack
slightly upward and away from the user's back forming an open area
between the waist support frame and the backpack support frame in
such a manner that this invention promotes proper anatomic posture
and healthy back alignment positioning while in use.
[0012] These and other objects, features, and/or advantages may
accrue from various aspects of embodiments of the present
invention, as described in more detail below.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
[0030] Particular embodiments of the present invention will now be
described in greater detail with reference to the figures. The use
of the term "backpack" is intended to be broadly interpreted to
cover various types of items, packs, and/or containers which may
carry a substantial load by a user on their back. Likewise, the
backpack may be a particular item having a substantial load which
may be carried upon a user's back. For example, a backpack may
include a tank, a child or animal carrier, a storage compartment
for holding books, camping gear, a tent, a surfboard, a canoe,
and/or any other type of item or container capable of possessing
and/or supporting a load.
[0031] FIG. 1 illustrates a side view of a modular backpack load
carrying system 10 adapted for use with a backpack 4. FIG. 2 shows
a perspective view of the modular backpack load carrying system 10
without the backpack 4. As shown, the straps 6 of the backpack 4
are carried over the shoulders 3 of the user 2. The backpack load
carrying system 10 includes a waist support 20 into which a portion
of the load from the weight of the backpack 4 and its contents are
biased onto the waist of the user 2. The waist support frame 30 is
connected through a return connection 50 to a backpack support
frame 40. The waist support frame 30 and the backpack support frame
40 are positioned relative to each other at an optimum
predetermined angle .theta. that is selected to comfortably
distribute the load of the backpack 4 to the hips and lumbar of the
user 2 via the waist support 20, and to the shoulders 3 of the user
2 through the backpack straps 6.
[0032] An angular range over which the waist support frame 30 and
the backpack support frame 40 may be positioned may lie in the
range between approximately 3 to 45 degrees, and preferably may be
positioned at about 15 degrees for optimum distribution of the
load. The angular range may vary based on the size, shape and
configuration of the backpack load carrying system 10 and the
backpack 4 being carried as well as the size and shape of the user
2.
[0033] The backpack load carrying system 10 is adapted for use in a
variety of different implementations. For example, the backpack
load carrying system 10 may be used with a student's backpack, a
military backpack, a camping/hiking backpack, to carry large and
small items, such as a tent or a surfboard and/or any other item
that may be adapted and carried by the user.
[0034] FIG. 3 illustrates the normal use and wear of a conventional
backpack 4. As shown, the vertical force F.sub.V and the resultant
force F.sub.L are the same. That is, the entire load F.sub.L from
the backpack 4 is directed vertically through the shoulder straps 6
onto the shoulders 3 of the user 2. Traditionally, the force from
the load F.sub.L of the backpack 4 causes severe discomfort to the
user 2. The user 2 will attempt to compensate for the additional
load by hunching forward to offset and balance the extreme load
pulling backward by the weight of the backpack 4. The consequence
of the user's overcompensation results in poor posture and
eventually can cause severe pain and/or discomfort to the spine of
the user 2.
[0035] Referring to FIGS. 2 and 4, the waist support 20 includes a
main section 22 that curls into side flaps 24 at its ends. The main
section 22 is attached to the waist support frame 30. As shown, the
side flaps 24 are contoured to wrap around the waist 5 of the user
2.
[0036] FIG. 5 shows that the waist support 20 may be constructed of
a material that is comfortable when placed against the waist 5 of
the user 2. The waist support 20 may be lined with a soft material
fabric, such as for example, a foam cushioned material fabric,
and/or any other type of cushioning suitable for providing comfort
to the user 2. Likewise, during manufacture and assembly, all rough
edges and abrasions from the construction of the backpack load
carrying system 10 may be smooth for safety and comfort.
[0037] FIG. 6 shows that the waist support 20 may be attached to
the waist support frame 30 by a plurality of fasteners 26. Various
types of fasteners may be used, including but not limited to,
screws, rivets, pins, snap-lock fasteners, and/or any other type of
fastener capable of securing the waist support 20 to the waist
support frame 30, and/or other components to each other. The waist
support 20 may be constructed so that the waist support 20 may be
slidably guided into place and is locked into position adjacent to
the waist support frame 30 at a predetermined location. Various
mechanisms may be employed to slidably position the waist support
20 into position, such as by disposing a track on the waist support
20 and a mating rail on the waist support frame 30 for receiving
the mating track and aligning the waist support 20.
[0038] FIGS. 6 and 7 show the waist support frame 30 including a
first waist support frame member 32 and a second waist support
frame member 34 that extend from the waist support 20 to the return
connection 50. As shown, the return connection 50 may be
constructed as a rod 51 that spans across to secure upper ends of
the first waist support frame member 32 and the second waist
support frame member 34.
[0039] The return connection 50 may also secure the upper end of
the backpack support frame 40. As shown in FIGS. 4 and 6-7, the
backpack support frame 40 includes an angular return portion 41
formed at the upper end of the backpack support frame 40 that
connects to the return connection 50.
[0040] Referring to FIGS. 2 and 4-6, the backpack support frame 40
is constructed to include a first backpack support frame member 42
and a second backpack support frame member 44. As shown in FIGS. 2
and 4, the first backpack support frame member 42 and the second
backpack support frame member 44 extend from the return connection
50 in an acute angular direction .theta. relative to the waist
support frame 30 that provides a cantilever effect in which the
weight of a load experienced by the backpack 4 is distributed, in
part, through the backpack load carrying system 10 to the waist
support frame 30 and onto the waist 5 of the user 2.
[0041] A first lateral backpack support frame member 46 extends
across and connects the lower peripheral ends of the first backpack
support frame member 42 and the second backpack support frame
member 44. Likewise, an intermediate lateral backpack support frame
member 48 extends across an intermediate portion of the first
backpack support frame member 42 and the second backpack support
frame member 44.
[0042] FIGS. 4 and 6 illustrate providing a securing mechanism 60
on at least one of the first lateral backpack support frame member
46 and the intermediate lateral backpack support frame member 48.
The purpose of the securing mechanism 60 is to secure the backpack
4 to the backpack support frame 40. Various types of securing
mechanisms 60 may be employed, including but not limited to:
Velcro, snaps, a zipper, a sleeve or a pocket, and/or any other
type of mechanism capable of securing the backpack 4 to the
backpack support frame 40. By way of example, FIG. 1 depicts a
lower portion of the backpack support frame 40 being secured to the
backpack 4 by having at least one end of the backpack support frame
40 being tucked into a securing pocket 62 disposed on the backpack
4.
[0043] Referring back to FIGS. 1 and 4, an angle .theta. is defined
by the relative positioning of the return connection 50 and the
cantilevered angular return portion 41 of the backpack support
frame 40. The object of providing an angle .theta. between the
backpack support frame 40 and the waist support frame 30 is to
comfortably distribute the weight of the load F.sub.L of the
backpack 4. Instead of having the entire load F.sub.L being
directly applied to the shoulders 3 of the user 2 through the
shoulder straps 6, the load F.sub.L is distributed in portions to
the straps 6 of the backpack 4, and through the waist support 20 to
the hips and waist 5 of the user 2.
[0044] Likewise, it is important to note that the material
properties and composition of the waist support frame 30, the
return connection 50, and the backpack support frame 40 influence
the amount of resilient angular displacement the waist support
frame 30 and the backpack support frame 40 will flex relative to
each other. Softer materials will generally allow for greater
flexibility, than will more rigid materials. The length of the
waist support frame 30 and the backpack support frame 40 will also
influence the amount of angular 0 displacement the backpack load
carrying system 10 will incur.
[0045] Referring to FIG. 3, conventionally only one force F.sub.L
is evident. That is, the vertical force F.sub.V and the resultant
force F.sub.L of the load are equal because the backpack 4 lies
flat against the user's 2 back and no horizontal force component is
produced. All of the weight F.sub.L of the backpack 4 is directed
downward and carried entirely onto the shoulder straps 6.
Consequently, when the backpack is overloaded, severe discomfort is
experienced by the user 2 from the strain by the weight at the
shoulder straps 6.
[0046] Referring back to FIG. 1 in more detail, the force F.sub.L
represents the resultant gravitation force of the load of the
backpack 4 and the contents therein. By employing the backpack load
carrying system 10 in accordance with this invention, the backpack
4 is slightly elevated so that the resultant gravitation force
F.sub.L generated from the load of the backpack 4 produces two
force components. A vertical force component F.sub.V and a
horizontal force component F.sub.H.
[0047] In use, the bottom of the backpack 4 of the user 2 is
propped angularly upward at an acute angle .theta., slightly
outward and away from the user's back. An open area 52 is formed
between the waist support frame 30 and the backpack support frame
40. The acute angle .theta. is formed between the waist support
frame 30 and the backpack support frame 40 which, as a result,
causes the gravitational force of the resultant load F.sub.L to
produce a horizontal force component F.sub.H and vertical force
component F.sub.V.
[0048] The horizontal force of the load F.sub.H is translated
through the frame (40, 50, 30, 20) of the backpack load carrying
system 10 horizontally to the hips and waist 5 of the user 2. As a
result, the vertical force component F.sub.V is substantially
reduced, and therefore less of the vertical force F.sub.V is
distributed to the user's 2 shoulders 3 through the straps 6. The
advantage of this construction is that less force, and therefore
less weight from the backpack 4 impinges vertically downward
cutting into the user's 2 shoulders 3 through the shoulder straps 6
of the backpack 4.
[0049] The distribution of force to the waist support 20,
alleviating the entire load off of the shoulders 3 makes wearing
the backpack 4 more comfortable. The weight of the backpack 4 is
not entirely felt on the shoulders 3, but instead a distributed
portion of the load is transferred instead to the waist 5 of the
user 2. Redistributing a portion of the load to the waist 5 also
acts to counteract the weight of the bag which conventionally
caused the user 2 to hunch forward. Therefore, the user is
comfortable standing upright and prone to maintaining better spinal
alignment. Proper anatomical alignment is promoted thereby enabling
the user 2 to walk naturally upright and with good posture.
[0050] Another advantage of the backpack load carrying system 10 is
that the open gap 52 (as shown in FIG. 1) formed between waist
support frame 30 and the backpack support frame 40 allows for ample
aeration of heat and perspiration that would otherwise build up in
the open area gap. As such, the user 2 may keep cooler carrying
their backpack 4 and will not suffer from unsightly sweaty and/or
drenched back to their garment when removing their backpack 4 as is
characteristic of wearing a backpack in a conventional manner.
[0051] Various constructions may be used in accordance with this
invention. It is to be understood that the backpack load carrying
system 10 may be made as a single integral piece construction, or
made be made of various modular components in construction.
[0052] FIGS. 8-14 illustrate the modular adjustable construction of
various components of the backpack load carrying system 10. In
particular, FIGS. 8-9 depict a modular waist support bracket 120
including a first adjustable waist support 20a and a second
adjustable waist support 20b. The modular waist support bracket 120
may be made of any suitable number of pieces. As shown, the modular
waist support bracket 120 includes a center plate 21 adjustably
connected to intermediate plates 23 disposed on either side of the
center plate 21. The intermediate plates 23 are connected at their
peripheral edge to a pivot joint 27, which in turn is connected to
an adjustable outer plate 25.
[0053] The center plate 21 and the intermediate plates 23 include
an adjustable mechanism comprising of a variety of slots 28 through
which adjustable fasteners 26 are disposed. The adjustable
fasteners 26 slide within the adjustable slots 28 thereby
permitting the modular waist support bracket 120 to adjust to a
variety of users having a number of different sizes and shapes. The
outer plates 25 are curved and may be hinged at the pivot joint 27
to adjust to users of different sizes. The outer plates 25 may be
pivoted inward and outward for adjustment purposes.
[0054] In use, for a smaller waist 5 person, the center plate 21
and the intermediate plates 23 may be adjusted in close alignment
together, and the outer plates 25 may be brought more inward to
support the smaller waist 5 of the user 2. However, for a larger
waist 5 person, the center plate 21 and the intermediate plates 23
would be adjusted farther from each other, and the outer plates 25
may be pushed outward to support the larger waist 5 of the user
2.
[0055] FIGS. 10-12 show various modular constructions for an
adjustable connection made by the waist support frame 30, the
backpack support frame 40 and the return connection 50. For
example, FIG. 10 illustrates a first exemplary connection between
the waist support frame 30 and the backpack support frame 40 at the
return connection 50. As shown, the angular return portion 41 of
the backpack support frame 40 surrounds the return connection 50.
The peripheral edge of the return connection 30 is positioned
within the return connection 50. The backpack support frame 40, the
return connection 30 and the return connection 50 are all fastened
together by securing an adjustable fastener 26 thereto.
[0056] FIG. 11 illustrates a second exemplary connection between
the waist support frame 30, the backpack support frame 40 at the
return connection 50. As shown, the backpack support connection 30
includes an adjustment fastener 26 disposed between the backpack
return connection 30 and a second backpack return connection 30a.
The backpack return connection 30 and the second backpack return
connection 30a are adjustable, for example by a slot 28 (as shown
in FIG. 9), and connected to each other at an adjustable fastener
portion 26 disposed there between. As such, the backpack return
connection 30 may be slidably adjusted relative to the second
backpack return connection 30a for optimum sizing of the user 2. In
use, the angular return portion 41 of the backpack support frame 40
surrounds the return connection 50. The peripheral edge of the
second return connection 30a is fastened by fastener 26 to the
return connection 50. The backpack return connection 30 is secured
to the second backpack return connection 30a by an adjustable
fastener 26.
[0057] FIG. 12 illustrates another exemplary connection between the
waist support frame 30 and the backpack support frame 40 at the
return connection 50. According to this embodiment, the waist
support frame 30 is integrated as part of the return connection 50.
In use, the angular return portion 41 of the backpack support frame
40 is returned at a predetermined angle inwardly and positioned
within the return connection 50. The angular return portion 41 is
then secured to the return connection 50 by an adjustable fastener
26. The peripheral edge of the angular return portion 41 may be
suitably adjusted into a preferred position according to the user's
preference.
[0058] FIG. 12 also shows the integration of a belt strap fastener
for securing the backpack load carrying system 10 to the waist 5 of
the user 2. In this exemplary embodiment, the belt strap fastener
is depicted as a snap-lock buckle fastener 242. The snap-lock
buckle fastener 242 includes a first strap 243 attached to a first
end of a side flap 24 and a second strap 244 attached to a second
end of the other side flap 24.
[0059] FIG. 12 illustrates that the design of the backpack load
carrying system 10 is flexible and may be constructed in a variety
of different ways. For example, and as shown, a first lateral waist
support frame member 33 may be disposed laterally across the waist
support frame 30. Likewise, a second lateral waist support frame
member 35 may also be disposed laterally across the waist support
frame 30 for added support and stability.
[0060] FIG. 12 shows the first lateral backpack support frame
member 46 and the intermediate lateral backpack support frame
member 48 being disposed on a side adjacent to the open gap 52. A
plurality of button snap fasteners 43 are shown disposed on an
outside of the backpack support frame 40. The button snap fasteners
43 may be used to affix, various items, such as the backpack 3
and/or infant seat 160 as will be discussed in more detail later.
Likewise, it is also within the scope of this invention to adapt
the backpack load carrying system 10 for carrying various types of
items, small and large, such as a surfboard, a skateboard, and/or
any other object,
[0061] FIGS. 13-14 show that the backpack support frame 40 may also
be modularly constructed. The backpack support frame 40 is attached
to a return connection 51 made as a single piece construction. The
return connection 51 includes receiving apertures 51a, 51b adapted
to receive the peripheral ends 30b of the waist support frame 30,
and the peripheral ends 40b of the backpack support frame 40,
respectively. The receiving apertures 51a, 51b are spaced apart at
a predetermined angle .theta. suitable to space the waist support
frame 30 from the backpack support frame 40.
[0062] As shown in FIG. 13, the backpack support frame 40 includes
a first backpack support frame member 42c, and a second backpack
support frame member 44c whose peripheral ends 40b connect into the
return connection 51. The backpack support frame 40 further
includes a first lateral backpack support frame member 46c whose
peripheral ends 46a connect into a pair of snap-lock housings 43
disposed at the lower end of the first backpack support frame
member 42c and the second backpack support frame member 44c
respectively. Likewise, the backpack support frame 40 includes an
intermediate lateral backpack support frame member 48c whose
peripheral ends 48a connect into another pair of snap-lock housings
43 disposed at an intermediate position on the first backpack
support frame member 42c, and at an intermediate position on the
second backpack support frame member 44c.
[0063] In use, and as shown in FIG. 13, the peripheral end 40b of
the backpack support frame 40 is inserted and locked into the
receiving aperture 51b. Likewise, the peripheral end 30b of the
waist support frame 30 is inserted and locked into the receiving
aperture 51a.
[0064] As shown in FIG. 13, the peripheral end 40b of the backpack
support frame 40 is constructed in combination with the receiving
aperture 51b as a snap-lock fastener. When the snap-lock fastener
end 46c is positioned within the receiving aperture 51b, flared
portions of the snap-lock fastener 46c are captivated by
protrusions 52b such that the backpack support frame 40 is locked
into position for use. The same locking operation is similar for
the peripheral end 30b of the waist support frame 30 when it is
inserted and into the receiving aperture 51a.
[0065] FIG. 13 also shows that lateral backpack support frame
members 46c, and intermediate lateral backpack support frame member
48c may also be secured into place using similarly constructed
peripheral ends 46a and 48a, respectively. By way of example, FIG.
13 depicts in detailed cross-section, the peripheral end 48a of the
intermediate lateral backpack support frame member 48c disposed and
secured within a snap-lock housing 43. The snap-lock housing 43 may
be secured via flanges 45 and a fastener 26 to various positions on
the backpack support frame 40. The snap-lock housing 43 includes a
receiving aperture 48b into which the peripheral end 48a is
disposed. When the snap-lock fastener 48d is positioned within the
receiving aperture 48b, flared portions 48d of the snap-lock
fasteners 48d are captivated by protrusions 52b and the
intermediate lateral backpack support frame member 48c is locked
into position for use. The same applies for the lateral backpack
support frame member 46c.
[0066] Although various snap-lock fasteners are shown in FIG. 13,
it is to be understood that various connections may used throughout
this invention to attach the various components to each other,
and/or any other type of connection now known, or later discovered,
in accordance with this invention.
[0067] These embodiments demonstrate the flexibility in which the
backpack load carrying system 10 and the modular infant carrying
system 100 as will be described below may be designed and
constructed in accordance with this invention. It is to be
understood that a variety of different configurations may be used
without departing from the scope of this invention and these
embodiments are not intended to limit the scope of this
invention.
[0068] FIGS. 15-19 illustrate another exemplary embodiment in which
the backpack load carrying system 10 may be adapted for use as a
modular infant carrying system 100. As shown in FIG. 15, the
modular infant carrying system 100 includes a waist support 20
connected to a waist support frame 30. The waist support frame 30
is connected to an infant support frame 140 through a return
connection 50. The infant support frame 140 is attached to an
infant seat 160.
[0069] The infant seat 160 includes a seat 162 with legs cut-outs
164 through which an infant 7 may rest their legs and be supported.
The infant seat 160 includes a seat backing 166 and side panels 168
for securing the infant 7 within the infant seat 160. The infant
seat 160 may be lined with a soft material to comfortably cushion
the infant 7 during transport.
[0070] FIGS. 17 and 18 illustrate an exemplary embodiment for
securing the infant seat 160 to the infant support frame 140 via a
plurality of fasteners 142, 142a. In this embodiment, the fasteners
142, 142a may be integrated as part of the infant seat 160. As
shown in FIG. 19, the fasteners 142 include a hook-like return 143
portion that hooks around the infant support frame member 44a and
is secured to a portion of the infant support frame 140. The
fasteners 142 may be clamped to the infant support frame 140 in a
variety of different ways, such as with a screw 142b and/or
employing any other locking mechanism. The fasteners 142 may be
constructed in a number of different ways, including but not
limited to, a clamp, a clasp, a hook, a claw, and any other
suitable means for the fastening the infant seat 160 to the infant
support frame 140.
[0071] FIG. 17 is a front side view of the modular infant carrying
system 100. The infant support frame 140 includes a first infant
support frame member 42a and a second infant support frame member
44a. Similar to the backpack load carrying system 10 (and as shown
in FIG. 15), the first infant support frame member 42a and the
second infant support frame member 44a extend from the return
connection 50 in an acute angular direction .theta. relative to the
waist support frame 30.
[0072] A first lateral infant support frame member 46a extends
across and connects the lower peripheral ends of the first infant
support frame member 42a and the second infant support frame member
44a. Likewise, an intermediate lateral infant support frame member
48a extends across an intermediate portion of the first infant
support frame member 42a and an intermediate portion of the second
infant support frame member 44a.
[0073] Various fasteners 142, 142a are depicted to demonstrate the
different ways that the infant seat 160 may be attached to the
infant support frame 140. Fasteners 142 are adapted to be secured
to the first infant support frame member 42a and the second infant
support frame member 44a by constructing the fasteners 142 with a
return 143 portion.
[0074] FIG. 19 depicts the fastener 142 being constructed in a
hook-like shape to surround the infant support at least one of the
frame members 42a, 44a, 46a, 48a. The fasteners 142, 142a may be
constructed to be flexibly stretched around the various infant
support members 42a, 44a, 46a, 48a on the infant support frame.
Likewise, and as shown in FIG. 19, the fasteners 142, 142a may
include a pivot point 144 adapted to allow the return 143 to close
over the various infant support members 42a, 44a, 46a, 48a.
[0075] FIG. 19 further depicts securing the fastener 142 to an
infant support frame member 42a by a threaded fastener 142b. The
threaded fastener 142b may be included to provide additional
support to secure the fastener 142 to the infant support frame
member 42a.
[0076] As shown in FIG. 17, the fasteners 142, 142a may be
configured to snugly sit adjacent to, and/or be supported on top of
at least one of the lateral infant support frame members 46a, 48a
and/or on the infant support members 42a, 44a. For example, the
fastener 142a is shown in an elongated construction which hooks
onto the lateral infant support frame member 48a. Another elongated
fastener may be provided to hook onto the lateral infant support
frame member 46a to provide additional security of the infant seat
160. It is to be understood that various configurations for
providing a number of different fasteners 142 to the infant support
frame 140 may be provided.
[0077] FIG. 18 depicts another exemplary embodiment in which the
fasteners 142 include adjustable arms 146 which may be extended so
that the fasteners 142, 142a may be secured to the various infant
support members 42a, 44a, 46a, 48a. Likewise, and as shown in FIGS.
17 and 18, any combination of fasteners 142, 142a may be employed
to secure the infant seat 160 to the infant support frame 140.
[0078] The frame for the modular infant carrying system 100 is
constructed similar in design to the modular backpack load carrying
system 10. As shown in FIG. 15, the straps 6 are also adapted for
use with the infant carrying system 100. The straps 6 of the
backpack 4 are also carried over the shoulders 3 of the user 2. The
infant carrying system 100 includes a waist support 20 into which a
distributed portion of the load of the backpack 4 is directed onto
the waist 5 of the user 2. The waist support frame 30 is connected
to the infant support frame 140 through a return connection 50. The
waist support frame 30 and the infant support frame 140 are
positioned relative to each other at a predetermined angle .theta.
that is conducive for comfortably distributing the load of the
infant 7 to both, the hips and waist 5 by the waist support 20, and
to the shoulders 3 of the user 2 by the straps 6.
[0079] Another advantage realized by the infant carrying system 100
is that the connection between the waist support frame 30 and the
infant support frame 140 may be constructed of resilient materials
capable of resiliently flexing (without fatigue) and thereby
absorbing shock generated by the steps taken by the user 2.
Likewise, the return connection 50 may be constructed with a bias
element (not shown) capable of absorbing the shock from the user's
step, thereby dissipating the shock experienced by the infant 7. As
a result, the infant 7 will experience a smoother, more comfortable
ride while seated in the infant carrying system 100.
[0080] Various materials may be used for the various components in
accordance with this invention, including, but not limited to
metal, a polymer, fabric, and the like.
[0081] According to this invention, the modular infant carrying
system 100 also promotes good posture and an anatomical spinal
alignment is ensured thereby enabling the user 2 to walk naturally
upright with good posture.
[0082] It will be recognized by those skilled in the art that
changes or modifications may be made to the above described
embodiments without departing from the broad inventive concepts of
the invention. It is understood therefore that the invention is not
limited to the particular embodiments which are described, but is
intended to cover all modifications and changes within the scope
and spirit of the invention.
