Abstract
Described is a load-bearing support apparatus and system
including an upper and lower support element adapted to rotate
about one or more axes. The support elements can each further
include support couplings. The apparatus can further include first
and second support elements that can be adapted to bear the weight
of a load along vertical and horizontal axes, respectively. The
apparatus can include a mounting support element that can include
upper and lower load connectors that can further be coupled to the
load. The upper and lower load connectors can each be coupled to
the upper and lower support couplings, respectively, in a
ball-and-socket joint configuration. Because the ball-and-socket
joints can create an articulating motion based on an operator's
movement, the support apparatus can increase an operator's range of
motion resulting in greater comfort and less fatigue while
supporting the load.

BACKGROUND OF THE INVENTION
[0004] 1. Field of the Invention
[0005] The inventions disclosed and taught herein relate generally
to articulated backpack apparatus and systems. In one of the
aspects, the invention relates specifically to an apparatus capable
of supporting a load that can be adapted to create an articulating
motion based on an operator's movement. In further aspects, the
invention relates to a system that can include a portable vacuum
device. In this aspect, the above described articulating motion can
increase an operator's range of motion while operating the vacuum
device thus resulting in greater comfort and less fatigue during
its operation. In further aspects, the apparatus can be used to
support a load, such as portable tools, containers, equipment, or
the like.
[0006] 2. Description of the Related Art
[0007] Portable vacuum cleaners, such as ones mounted to a backpack
or other harness-type support, are commonly used across a variety
of applications and environments. These vacuum cleaners are a
convenient alternative to traditional vacuum cleaners because of
their increased mobility and portability. For example,
backpack-style vacuum cleaners are often used in commercial
environments, such as office buildings, because they allow the
operator to quick move from room to room with minimal interruption.
Furthermore, backpack-style vacuum cleaners can be used in cramped
or crowded environments that may otherwise be difficult or
impossible for traditional style vacuum cleaners to reach, such as
on buses, trains, and in subways.
[0008] There are several types of backpack-style vacuum cleaners
currently on the market. These vacuum cleaners typically employ
some sort of harness that is secured around an operator's
shoulders, hips, or both. For example, U.S. Pat. No. RE37,081 to
Eriksen describes a backpack vacuum cleaner that includes a hip
strap and a pair of shoulder straps for supporting a vacuum
cleaner. The straps are designed to minimize any limitations on the
operator's freedom of movement in the upper body when operating the
vacuum cleaner. Furthermore, the backpack is designed to
efficiently distribute the weight of the vacuum device because the
majority of its weight is carried by a hip strap, thus leaving the
operator's upper body and arms relatively unencumbered.
[0009] U.S. Pat. No. 5,267,371 to Soler, et al. describes a
cyclonic back-pack vacuum cleaner that includes a back-pack type
harness, an upper casing attached to the harness and a lower casing
rotatably mounted on the upper casing. The vacuum cleaner is
described to be ergonomically designed and light weight to minimize
an operator's fatigue during extended operation.
[0010] U.S. Patent Publication No. 2005/0086762 to Paris describes
a bagless portable backpack vacuum cleaner with bottom-mounted
inlet hose. The portable backpack vacuum cleaner is carried on the
back of an operator through the aid of shoulder and belt straps.
The portable backpack includes a large back harness which is
attached to the main vacuum body. The harness can be fitted around
the body of an operator to further support the portable vacuum
cleaner.
[0011] The problem with these solutions, however, is that operators
wearing backpack-style harnesses are often limited in their range
of motion by the design of the shoulder straps. More specifically,
when properly worn, the shoulder straps in these earlier solutions
are under constant tension which can effectively pin the operator's
shoulders against the vacuum cleaning device. This tension creates
resistance in the opposite direction when the operator is working
with his upper extremities. This, in turn, can place an undue
strain on the operator, thus resulting in fatigue and
discomfort.
[0012] What is required, therefore, is a back-pack style harness
that provides an operator with the freedom to rotate and flex
naturally while minimizing the strains and stresses on the
operator's body. Furthermore, a back-pack style harness solution is
required to allow the attached load to remain as close as possible
to the operator's center of gravity irrespective of her movements
throughout the operation of the vacuum device in order to improve
the operator's overall balance while minimizing fatigue.
[0013] Accordingly, the inventions disclosed and taught herein are
directed to a load-bearing support apparatus and system that
overcomes the problems set forth above.
BRIEF SUMMARY OF THE INVENTION

[0042] Applicants have created a load-bearing support apparatus and
system including an upper and lower support element adapted to
rotate about one or more axes. The support elements can each

include first and second support elements that can be adapted to
bear the weight of a load along vertical and horizontal axes,
respectively. The apparatus can include a mounting support element
that can include upper and lower load connectors that can further
be coupled to the load. The upper and lower load connectors can
each be coupled to the upper and lower support couplings,
respectively, in a ball-and-socket joint configuration. Because the
ball-and-socket joints can create an articulating motion based on
an operator's movement, the support apparatus can increase an
operator's range of motion resulting in greater comfort and less
fatigue while supporting the load.
[0043] In another embodiment, the apparatus can include an upper
support element that can be adapted to rotate about at least one
axis with respect to a load and a lower support element that can be
adapted to rotate about at least one axis with respect to the load.
The apparatus can further include a first support element that can
be adapted to bear at least a portion of the weight of the load and
a second support element that can be adapted to bear at least a

first support element that can be adapted to bear at least a
portion of the weight of the load. The apparatus can further
include a first support element extension that can be adapted to
provide support to the first support element and a second support
element that can be adapted to bear at least a portion of the
weight of the load. The apparatus can further include a support
element fastener that can be adapted to receive the first support
element extension and a mounting support element that can be
adapted to be coupled to a load.
[0045] In yet another embodiment, the system can include a load and
a load-bearing support apparatus, the apparatus can include an
upper support element that can be adapted to rotate about at least
one axis with respect to the load and a lower support element that
can be adapted to rotate about at least one axis with respect to
the load. The system's apparatus can further include a first
support element that can be adapted to bear at least a portion of
the weight of the load, a second support element that can be
adapted to bear at least a portion of the weight of the load, and a
mounting support element that can be adapted to be coupled to the
load. The load can include a portable vacuum device or assembly, a
portable tool, portable equipment, or the like.
[0046] Turning now to the figures, FIG. 1 illustrates an isometric
side view of a first embodiment of a load-bearing support apparatus
2. FIG. 2 illustrates an isometric back view of a first embodiment
of the load-bearing support apparatus 2. FIG. 4 illustrates a
side-view of the embodiment shown in FIGS. 1 and 2. These figures
will be described in conjunction with one another.
[0047] The apparatus 2 can include an upper support element 4 that
can be adapted to rotate about at least one axis with respect to a
load 42 (as shown in FIG. 4), and an upper support coupling 6 that
can be adapted to control the rotation of the upper support element
4 with respect to the load 42. The upper support element 4 can
further include an upper support resting unit 8 that can be adapted
to contact an upper portion of an operator 43 (FIG. 4).
[0048] The apparatus 2 can further include a first support element
10 that can be adapted to bear at least a portion of the weight of
the load 42, a center support element 12 that can be adapted to
provide support to the first support element 10, and a support
connector 14 that can further be adapted to couple the upper
support element 4 to a lower support element 20. The lower support
element 20 can be adapted to rotate about at least one axis with
respect to the load 42. The apparatus 2 can further include a
second support element 16 that can be adapted to bear at least a
portion of the weight of the load 42 and a side support element 18
that can be adapted to provide support to the second support
element 16.
[0049] Furthermore, the apparatus 2 can include a lower support
coupling 22 that can be adapted to control the rotation of the
lower support element 20 with respect to the load 42. The lower
support element 20 can further include a lower support resting unit
24 that can be adapted to contact a lower portion of an operator
43. The apparatus 2 can further include a mounting support element
26 that can be adapted to be coupled to the load 42. The mounting
support element 26 can further include an upper load connector 27
and a lower load connector 28. The upper load connector 27 can be
adapted to be coupled to the upper support coupling 6 and the lower
load connector 28 can be adapted to be coupled to the lower support
coupling 22.
[0050] The upper support element 4 can include any plate, support,
brace, stay, or any other feature for imparting support or rigidity
when the apparatus 2 is coupled to an operator 43. For example, the
upper support element 4 can include a thin sheet or plate of
plastic or any other synthetic or semi-synthetic organic solid or
polymer. The upper support element 4 can be embodied as a support
structure of varying shapes and sizes that can provide sufficient
support to the operator 43 while the upper support element 4
rotates about one or more axes. For example, the upper support
element 4 can include a shoulder support plate for supporting the
shoulders and upper back of an operator 43.
[0051] The upper support coupling 6 can include any joint,
connector, coupling, socket, hinge, pivot, or any other junction
that is adapted to control the rotation about at least one axis. In
an exemplary and non-limiting illustrative embodiment, the upper
support coupling 6 can include a socket portion of a
ball-and-socket joint. The upper support coupling 6 can be adapted
to be coupled to the upper support element 4 in order to allow the
upper support element 4 to rotate about at least one axis.
[0052] The upper support coupling 6 can further include a flexible
material adapted to control the rotation about at least one axis.
This flexible material can be used to create a joint, hinge, pivot,
or other junction between the upper support element 4 and a load
42. By virtue of its relatively high degree of flexibility, this
joint can create an articulating or rotating motion between the
upper support element 4 and the load 42. The flexible material can
include plastics, rubbers, polymers, or any other material with a
relatively low modulus of elasticity capable of flexing, bending,
twisting, or rotating. For example, the flexible material can have
a Young's modulus within the range from about 0.01 GPa to about
2.00 GPa.
[0053] The upper support resting unit 8 can include any pad,
buffer, cushion, or any other surface that can directly or
indirectly contact the upper portion of the operator 43 while the
apparatus 2 is coupled to the operator 43. For example, the upper
support resting unit 8 can include a layer of foam, rubber, foam
rubber, cloth, leather, or any other material suitable for
cushioning shock or vibration, or preventing excessive pressure or
chafing during use. In an exemplary and non-limiting illustrative
embodiment, the upper support resting unit 8 can include a layer of
cushioning, such as polyurethane foam, disposed between the
operator's 43 shoulder blades and the upper support element 4.
[0054] The first support element 10 can include any strap, belt,
looped band, brace, any other device for fastening, securing, or
supporting the weight of the load 42. For example, the first
support element 10 can include at least one shoulder strap that can
be secured around one or more of the operator's 43 shoulders. The
first support element 10 can be coupled to the upper support
element 4, the second support element 16, the side support element
18, the lower support element 20, the mounting support element 26,
or any combination thereof. Furthermore, the first support element
10 can include a vest, harness, or any other close-fitting
apparatus for supporting the weight of the load 42.
[0055] In an exemplary and non-limiting illustrative embodiment,
the first support element 10 can be made of cloth, nylon, ribstop,
or any other pliable or malleable material for supporting at least
a portion of the weight of the load 42. For example, the first
support element 10 can formed of a multi-layered material (e.g., a
polyethylene foam pad disposed between polyester outer shells
(e.g., coated or meshed, opened weaved, etc.)). Furthermore, the
length of the first support element 10 can be adjusted to
accommodate multiple heights of various operators 43. For example,
the first support element 10 can include adjustable straps that can
employ one or more adjustable portions, such as buckles, for
tightening or loosening the first support element 10.
[0056] The center support element 12 can include any strap, belt,
band, brace, or any other device for further fastening, securing,
or supporting the first support element 10. In an exemplary and
non-limiting illustrative embodiment, the first support element 10
can include two shoulder straps and the center support element 12
can include a strap interposed between the two first support
elements 10. In this example, the center support element 12 can be
embodied as a sternum strap that can provide support to help evenly
distribute the weight of the load 42 (FIG. 4). The length of the
center support element 12 can be adjusted to accommodate operators
43 (FIG. 4) of various sizes. For example, the center support
element 12 can employ one or more adjustable straps for tightening
or loosening the length of the center support element 12.
[0057] The support connector 14 can include any band, cord, cable,
webbing, or the like that can be adapted to couple the upper
support element 4 to the lower support element 20. The support
connector 14 can be employed to add rigidity, or in the
alternative, flexibility, between the upper support element 4 and
the lower support element 20. The support connector 14 can include
any band, rubber band, cord, cable, or a series of bands cords,
cables, spring, spring-type biasing device, or the like. In one
embodiment, the support connector 14 can include more than one
support connectors 14. For example, the apparatus 2 can include a
support connector 14 for each first support element 10.
Alternatively, the apparatus 2 can omit the support connector 14
altogether.
[0058] The second support element 16 can include any strap, belt,
looped band, brace, or any other device for fastening, securing, or
supporting the weight of the load 42. For example, the second
support element 16 can include at least one hip strap that can be
secured around one or more of the operator's 43 hips or waist. The
second support element 16 can be coupled to the first support
element 10, the side support element 18, the lower support element
20, the mounting support element 26, or any combination thereof.
The second support element 16 can be made of any material
previously described as a possible embodiment of the first support
element 10.
[0059] Furthermore, the second support element 16 can be adjusted
to accommodate multiple sizes of various operators 43. For example,
the second support element 16 can include an adjustable strap that
can employ one or more adjustable straps for tightening or
loosening the length of the first support element 10 to accommodate
different waist sizes of various operators 43. The second support
element 16 can be fastened by one or more snaps, buckles, buttons,
or any other fastening or coupling device for coupling two or more
materials together. For example, the second support element 16 can
include VELCRO.RTM. for releasably coupling two or more second
support elements 16.
[0060] The side support element 18 can include any plate, support,
brace, stay, or any other feature for imparting support or rigidity
when the apparatus 2 is coupled to an operator 43. For example, the
side support element 18 can include a thin sheet or plate of
plastic or any other synthetic or semi-synthetic organic solid or
polymer. The side support element 18 can be embodied as a support
structure of varying shapes and sizes that can provide sufficient
support to the operator 43 while the second support element 16 is
coupled to an operator 43. In one embodiment, the side support
element 18 can include a waist or support plate that is coupled to
the second support element 16. Furthermore, the side support
element 18 can be an extension of the lower support element 20 such
that the side support element 18 and the lower support element 20
are made from a single, monolithic piece of material.
[0061] The lower support element 20 can include any plate, support,
brace, stay, or any other feature for imparting support or rigidity
when the apparatus 2 is coupled to an operator 43. For example, the
lower support element 20 can include a thin sheet or plate of
plastic or any other synthetic or semi-synthetic organic solid or
polymer. The lower support element 20 can be embodied as a support
structure of varying shapes and sizes that can provide sufficient
support to the operator 43 while the lower support element 20
rotates about one or more axes. For example, the lower support
element 20 can include a hip or lower back support plate for
supporting the lower back and hips of the operator 43.
[0062] The lower support coupling 22 can include any joint,
connector, coupling, socket, hinge, pivot, or any other junction
that is adapted to control the rotation about at least one axis. In
an exemplary and non-limiting illustrative embodiment, the lower
support coupling 22 can include the socket portion of a
ball-and-socket joint. The lower support coupling 22 can be adapted
to be coupled to the lower support element 20 in order to allow the
lower support element 20 to rotate about at least one axis.
[0063] The lower support coupling 22 can further include a flexible
material adapted to control the rotation about at least one axis.
This flexible material can be used to create a joint, hinge, pivot,
or other junction between the lower support element 20 and a load
42. By virtue of its relatively high degree of flexibility, this
joint can create an articulating or rotating motion between the
lower support element 20 and the load 42. The flexible material can
include plastics, rubbers, polymers, or any other material with a
relatively low modulus of elasticity capable of flexing, bending,
twisting, or rotating. For example, the flexible material can have
a Young's modulus within the range of from about 0.01 GPa and about
2.00 GPa.
[0064] The lower support resting unit 24 can include any pad,
buffer, cushion, or any other surface that can directly or
indirectly contact the lower portion of the operator 43 (FIG. 4)
while the apparatus 2 is coupled to the operator 43 (FIG. 4). For
example, the lower support resting unit 24 can include a layer of
foam, rubber, foam rubber, cloth, leather, or any other material
suitable for cushioning shock or vibration, or preventing excessive
pressure or chafing. In an exemplary and non-limiting illustrative
embodiment, the lower support resting unit 24 can include a layer
of cushioning, such as polyurethane foam, disposed between the
operator's 43 lower back and the lower support element 20.
[0065] The mounting support element 26 can include any plate,
support brace, stay, or any other feature for imparting support or
rigidity when the apparatus 2 is coupled to a load 42. In an
exemplary and non-limiting illustrative embodiment, the mounting
support element 26 can include a plate that can be coupled to the
upper load connector 27, the lower load connector 28, the lower
support element 20, the upper support element 4, the load 42 or any
combination thereof. The mounting support element 26 can include
aluminum, carbon fiber, polypropylene, or any other lightweight
metals, plastics, or polymers capable of strengthening or
increasing the stability or rigidity of the apparatus 2.
[0066] The mounting support element 26 can be coupled to the load
42. Alternatively, the mounting support element 26 can be coupled
to the upper support element 4 and the lower support element 20
without the need to couple the mounting support element 26 to the
load 42. In this example, the apparatus 2 can be coupled to the
load 42 with the upper load connector 27, the lower load connector
28, or both.
[0067] The upper load connector 27 can include any joint, arm,
distal axis, or extension adapted to be coupled to the upper
support coupling 6. For example, the upper load connector 27 can
include the ball joint of a ball-and-socket joint. In this
configuration, if the upper load connector 27 is coupled to the
upper support coupling 6, the upper support coupling 6 (and the
elements coupled thereto) are capable of rotating up to and
including 360 degrees about multiple axes. This rotation is
described in greater detail in conjunction with FIGS. 5A, 5B, and
5C.
[0068] The position of the upper load connector 27 can be adjusted
to various heights to accommodate the heights of different
operators (not shown). For example, upper load connector 27 can be
coupled to the load 42 (as shown in FIG. 4) such that its height
with respect to the lower load connecter 28 can be quickly
adjusted. In an exemplary and non-limiting illustrative embodiment,
the upper load connector 27 can be slidably adjusted on a track or
the like so that these vertical adjustments can be quickly and
easily implemented. In other examples, various heights along the
vertical axis of the load 42 (as shown in FIG. 4) can be
predestinated (such as, for example, through slots, rivets, or the
like) to allow the upper load connector 27 to be moved from one
predestinated position to another.
[0069] Although the height of the lower load connector 28 can be
rigidly fixed with respect to load 42 (as shown in FIG. 4), in the
alternative, lower load connector 28 can be similarly embodied as
the lower load connecter 27 so that the vertical height of both the
upper load connector 27 and the lower load connector 28 can both be
adjusted with respect to one another.
[0070] The lower load connector 28 can include any joint, arm,
distal axis, or extension adapted to be coupled to the lower
support coupling 22. For example, the lower load connector 28 can
include the ball joint of a ball-and-socket joint. In this
configuration, if the lower load connector 28 is coupled to the
lower support coupling 22, the lower support coupling 22 (and the
elements coupled thereto) are capable of rotating up to and
including 360 degrees about multiple axes. This rotation is
described in greater detail in conjunction with FIGS. 5A, 5B, and
5C.
[0071] The upper load connector 27, the lower load connector 28, or
both connectors can further be coupled to the mounting support
element 26, the load 42 (as shown in FIG. 4), or both. Further, the
upper load connector 27 and the lower load connector 28 can include
a flexible material adapted to control the rotation about at least
one axis. This flexible material can be used to create a joint,
hinge, pivot, or other junction between the upper support element
4, the lower support element 20, and the load 42. By virtue of its
relatively high degree of flexibility, this joint can create an
articulating or rotating motion between the upper support element 4
and the load 42. The flexible material can include plastics,
rubbers, polymers, or any other material with a relatively low
modulus of elasticity capable of flexing, bending, twisting, or
rotating. For example, the flexible material can have a Young's
modulus within the range from about 0.01 GPa to about 2.00 GPa.
[0072] FIG. 3 illustrates a side view of a second embodiment of the
load-bearing support apparatus 30. The apparatus 30 can include an
upper support element (not shown) that can be adapted to rotate
about at least one axis with respect to a load 42 (as shown in FIG.
4), a first support element 32 that can be adapted to bear at least
a portion of the weight of the load 42 (as shown in FIG. 4), and a
second support element 34 that can be adapted to bear at least a
portion of the weight of the load 42. The apparatus 30 can further
include a first support element extension 35 that can be adapted to
provide support to the first support element 32. The first support
element extension 35 can be adapted to bear the weight of the load
42.
[0073] The apparatus 30 can further include a support element
fastener 36 that can be adapted to receive the first support
element extension 35 and a mounting support element 39 that can be
adapted to be coupled to the load 42. The support element fastener
36 can be adapted to secure the first support element extension 35
thereby creating tension in the first support element 32. Examples
of the first support element 32, the second support element 34, and
the mounting support element 39 can include similar embodiments as
disclosed for the first support element 10, the second support
element 16, and the mounting support element 26, respectively, as
described in conjunction with FIG. 1 and FIG. 2.
[0074] The first support element extension 35 can include one or
more straps, belts, looped bands, braces, any other devices for
further fastening, securing, or supporting the weight of the load
42 or providing additional support to the first support element 32.
For example, the first support element extension 35 can a include
strap that can extend from a terminating edge of each of the first
support elements 32. In this example, the first support element 32
can include two first support elements 32 that each include a first
support element extension 35. The first support element extensions
35 can further be adapted to cross at approximately ninety degree
angles in order maintain constant tension in the first support
elements 32. The first support element extensions 35 can be adapted
to cross one another at angles other than ninety degrees as
well.
[0075] The support element fastener 36 can include any guide,
fastener, channel, loop, hook, or other device for catching,
receiving, channeling, guiding, pulling, or holding the first
support element extension 35. In an exemplary and non-limiting
illustrative embodiment, the support element fastener 36 can
include a structure that extends outwardly from the mounting
support element 39 or the load 42 in order to create a cavity or
conduit for which the first support element extension 35 can be fed
through. The support element fastener 36 can be used to adjust the
tension on the first support element extension 35 so that constant
pressure is maintained throughout the first support element 32 when
the apparatus 30 is coupled to an operator 43.
[0076] FIG. 4 illustrates an isometric side view of a first
embodiment of a load-bearing support system 40. The system can
include a load-bearing support apparatus 41, a load 42, and an
operator 43. The system 40 can further include an upper load
connector 44 and a lower load connector 46. The upper load
connector 44 can be adapted to be coupled to an upper support
coupling 45 and the lower load connector 46 can be adapted to be
coupled to a lower support coupling 47.
[0077] The load-bearing apparatus 41 can include any harness,
backpack, vest, or any other device for coupling a load 42 to an
operator 43. For example, the load-bearing apparatus 41 can include
the apparatus 2 (as shown in FIG. 1) or the apparatus 30 (as shown
in FIG. 3). The load 42 can include a portable vacuum device (such
as a vacuum cleaner), a portable tool, portable equipment, or the
like. Furthermore, the load 42 can include any load capable of
being carried on the back of an operator 43. For example, the load
can include portable tools (such as leaf blowers, power washers or
the like), containers of compressed gases or fluids (such as
pesticides, herbicides, or liquid fertilizer compositions),
generators, power supplies, fuel supplies, or other tools or
equipment. In an example where the load 42 is a portable vacuum
device, the upper support resting unit 8 and the lower support
resting unit 24 can be formed such that the materials do not cover
portions of the vacuum's filters (not shown) or impede the flow
from or to the vacuum's outlets and inlets (not shown),
respectively.
[0078] The upper load connector 44 can include any joint, arm,
distal axis, or extension adapted to be coupled to the upper
support coupling 45. The lower load connector 46 can include any
joint, arm, distal axis, or extension adapted to be coupled to the
lower support coupling 47. The lower load connector 46 can further
include at least two load connectors. The upper load connector 44
and the upper support coupling 45 can be adapted to form a
multi-axis joint, such as a ball-and-socket joint. The lower load
connector 46 and the lower support coupling 47 can also be adapted
to form a ball-and-socket joint. Examples of the upper load
connector 44 and the lower load connector 46 can include similar
embodiments as the upper load connector 27 and the lower load
connector 28, respectively, as described in conjunction with FIG. 1
and FIG. 2.
[0079] The upper support coupling 45 and the lower support coupling
47 can include any joint, connector, coupling, socket, hinge,
pivot, or any other junction that is adapted to control the
rotation about at least one axis. In an exemplary and non-limiting
illustrative embodiment, the upper support coupling 45 and the
lower support coupling 47 can each include the socket portion of a
ball-and-socket joint. The upper support coupling 45 can be adapted
to be coupled to the upper support element (not shown) to allow the
upper support element to rotate about at least one axis and the
lower support coupling 47 can be adapted to be coupled to the lower
support element (not shown) to allow the lower support element to
rotate about at least one axis.
[0080] Because the upper support element 48 can rotate through an
almost infinite number of configurations among at least three axes
(as described in greater detail below in conjunction with FIGS. 5A,
5B, and 5C), the apparatus 41 can allow operators 43 to naturally
rotate or flex their bodies while maintaining the center of gravity
of the load 42 coupled to the apparatus 41. For example, if the
lower load connector 46 is embodied as two load connectors, the
lower support element (not shown) can rotate through a central axis
so that when one side of the lower support element (not shown)
raises, the other lowers, and vise-versa.
[0081] Likewise, when the upper support element 48 is coupled to a
ball-and-socket joint, the upper and lower ball-and-socket joints
can work in concert to further maximize the operator's 43 comfort
and minimize fatigue during operation. This can be accomplished by
allowing the upper support element 48 to rotate about a central
axis while maintaining constant tension within the first support
element (not shown). In other words, the upper support element 48
and the lower support element (not shown) can rotate in parallel
vis-a-vis the other in order to minimize the stresses and uneven
load balances on the operator 43.
[0082] FIG. 5A illustrates a detailed side view of an upper portion
of the load-bearing support apparatus illustrated in FIG. 1. FIG.
5B illustrates a detailed front view of an upper portion of the
load-bearing support apparatus illustrated in FIG. 1. FIG. 5C
illustrates a detailed top view of an upper portion of the
load-bearing support apparatus illustrated in FIG. 1. These figures
will be described in conjunction with one another.
[0083] In each of these figures, the upper support element 4 can
have a top portion 4T, a bottom portion 4B, a front portion 4F, a
rear portion 4R, a right side 4RS, and a left side 4LS. The upper
support resting unit 8 can be coupled to the front portion 4F.
Furthermore, the upper support element 4 can be coupled to the
upper support coupling 6. The upper support coupling 6 can be
coupled to the upper load connector 27 to form a multi-axis joint
29.
[0084] The multi-axis joint 29 can include any flexible joint that
can create an articulating or rotating motion between the two or
more elements of the apparatus 2 (as shown in FIG. 4) (e.g., upper
support element 4 and the load 42). The flexible material can
include plastics, rubbers, polymers, or any other material with a
relatively low modulus of elasticity capable of flexing, bending,
twisting, or rotating. For example, the flexible material can have
a Young's modulus within the range from about 0.01 GPa to about
2.00 GPa. Further, the multi-axis joint 29 can take the form of
various shapes and sizes that are suitable for rotation. For
example, the multi-axis joint 29 can include a cylindrically-shaped
piece of rubber or other flexible material. Other shapes and sizes
for the multi-axis joint 29 are contemplated as well. In a further
examples, the multi-axis joint 29 can include a universal joint,
gooseneck connector (e.g., coupled or clamped to various components
on the apparatus 2 (as shown in FIG. 1), or the like.
[0085] Each of the respective two-axes depicted in these figures
(as shown in dashed lines) form, in the aggregate, a standard
three-dimensional Cartesian coordinate system to further illustrate
the rotational aspects of the multi-axis joint 29. In this
illustration, the Z-axis can represent the vertical axis, the
Y-axis can represent the axis running parallel with the upper
support coupling 6, and the X-axis can represent the axis running
perpendicular to both the upper support coupling 6 and the
Z-axis.
[0086] The upper support element 4, when coupled to the multi-axis
joint 29, can rotate about at least three axes. For example,
referring to FIG. 5A, the upper support element 4 can rotate so
that the top portion 4T can pitch towards the front portion 4F or
the top portion 4T can pitch toward the rear portion 4R. In other
words, from this perspective, the upper support element 4 can
rotate clockwise or counterclockwise through the X-Y and X-Z
planes.
[0087] Additionally, referring to FIG. 5B, the upper support
element 4 can rotate so that the right side 4RS can pitch towards
the top portion 4T or the left side 4LS can rotate towards the top
portion 4T. In other words, from this perspective, the upper
support element 4 can rotate clockwise or counterclockwise through
the X-Y and Y-Z planes.
[0088] Referring to FIG. 5C, the upper support element 4 can rotate
so that the right side 4RS can rotate toward the rear portion 4R or
the left portion 4LS can rotate toward the rear portion 4R. In
other words, from this perspective, the upper support element 4 can
rotate clockwise or counterclockwise through the X-Z and Y-Z
planes.
[0089] In this configuration, the upper support element 4 can
freely rotate through nearly an infinite number of orientations
along the X, Y and Z axes. By doing so, the apparatus (not shown)
can allow operators (not shown) to naturally rotate or flex their
bodies while maintaining the center of gravity of the load (not
shown) coupled to the apparatus (not shown).
[0090] For FIGS. 6-8, many, but not all, of the illustrated
features of the described inventions share features with the
features described in FIGS. 1-5 above. For example, referring
specifically to FIG. 6A, the load bearing apparatus 102 illustrated
in this figure shares many common elements with the load bearing
support apparatus 2 illustrated in FIGS. 1 and 2, (e.g., upper
support element 4, first support element 10, lower support resting
unit 24, etc.). Moreover, the features illustrated in FIGS. 6-8
that correspond to a features illustrated in FIG. 1-5 are
identified in FIGS. 6-8 with labels that are offset by 100 from
their FIGS. 1-5 counterparts (e.g., element 4 of FIG. 1 corresponds
to element 104 of FIG. 6A; element 10 of FIG. 1 corresponds to
element 110 of FIG. 6A, and so on). All of these corresponding
features are described in detail with reference to FIGS. 1-5 and
thus, in the interest of clarity and brevity, will not be repeated
for the description for FIGS. 6-8. Accordingly, elements
illustrated in FIGS. 6-8 that correspond to elements labeled in
FIGS. 1-5 can be similarly embodied, where appropriate, as those
elements described in reference to FIGS. 1-5, and thus the
examples, references to, and description of those elements
illustrated in FIGS. 1-5, are equally applicable to their
corresponding elements in FIGS. 6-8.
[0091] FIG. 6A illustrates an isometric front view of a third
embodiment of the load-bearing support apparatus. FIG. 6B
illustrates a back view of the third embodiment of the load-bearing
support apparatus of FIG. 6A including a load. These Figures will
be described in conjunction with one another.
[0092] The apparatus 102 can include an upper support element 104
that can be adapted to rotate about at least one axis with respect
to a load 142. The apparatus 102 can further include a first
support element 110 that can be adapted to bear at least a portion
of the weight of the load 142, a center support element 112 that
can be adapted to provide support to the first support element 110,
and a lower support element 120. The lower support element 120 can
be adapted to rotate about at least one axis with respect to the
load 142. The apparatus 102 can further include a support connector
114, a lower support resting unit 124, a mounting support element
126, and a second support element 116 that can be adapted to bear
at least a portion of the weight of the load 142 and a side support
element 118 that can be adapted to provide support to the second
support element 116.
[0093] Additionally, the apparatus 102 can include a support
coupler 152, a tension adjuster 154, and a fastener 156. The
support coupler 152 can include any fastening or coupling device
for coupling the second support element 116 with the side support
element 118, the lower support element 120, or both. For example,
the support coupler 152 can include both the male and female
connectors to a buckle-type strap connector. In other examples, the
support coupler 152 can include one or more snaps, buttons, or the
like for releasably coupling and decoupling the second support
element 116 to or from one or more support elements of the
apparatus 102. Although not explicitly illustrated in all of the
figures, the support coupler 152 can be incorporated on other
various support elements of the apparatus 102 as well, including
but not limited to, the first support element 110, the center
support element 112, etc.
[0094] The tension adjuster 154 can include a strap, leash, tie, or
the like coupled to a quick-release mechanism for adjusting the
length and/or position of an electrical cord (not shown) of an
electrically powered device (such as, for example, if the load 142
is a vacuum or other powered appliance). This feature can be
employed by the operator (not shown), for example, to quickly
release a portion of the cord or to adjust its position.
[0095] The support adjuster 158 can include a guide, grip, loop,
cinch, or the like for adjusting the length of support connector
114 when it is coupled to the upper support element 104. Although
not explicitly shown in the figures, additional support adjusters
may be incorporated into other support elements of apparatus 102
for adjusting the length (and thus, the tension) in those supports.
In one example, the tension adjuster 154 can include a guide in
which the varying length of material forming the support connector
114 can be inserted or incorporated within to increase and decrease
the length of material between the lower support element 120 and
the upper support element 104. For example, as the height of the
upper support element 104 is adjusted (as described in greater
detail above), the length of the support connector 114 can be
adjusted accordingly with the aid of the support adjusters 158.
Further, the apparatus 102 can include a support adjuster 152, a
support switch 154, an accessory support 156, and one or more
support guides 164, as described in greater detail below in
conjunctions with FIGS. 7 and 8.
[0096] FIG. 7A illustrates an isometric back view of a lower
portion of the load bearing support apparatus. FIG. 7B illustrates
a front view of the lower portion of the load bearing support
apparatus illustrated in FIG. 7A. These Figures will be described
in conjunction with one another.
[0097] In addition to the lower support element 120, the lower
support resting unit 124, the mounting support element 126, the
support coupler 152, and the tension adjuster 154 as described
above, the lower portion of the apparatus 102 (as shown in FIG. 6A)
can include one or more fasteners 156, a support switch 160, and
one or more accessory supports 162.
[0098] The one or more fasteners 156 can include one or more
buttons, hooks, snaps, buckles, adhesives, or any other fastening
or coupling device for coupling two or more materials together. For
example, the one or more fasteners 156 can include VELCRO.RTM. for
releasably coupling two or more features of the inventions. In
another example, the one or more fasteners 156 can include rivets
for affixing and/or coupling two or more materials together. In
this example, the material used to form the lower support resting
unit 124 can be affixed to the lower support element 120 with one
or more of these rivets. This material, for example, can include
foam, rubber, foam rubber, cloth, leather, or any other material
suitable for cushioning shock or vibration, or preventing excessive
pressure or chafing during use. Further, the one or more fasteners
156 can be employed in other features of the apparatus 102 as well
(for example, in one or more locations disposed on the upper
support resting unit 104 as illustrated in FIG. 8A).
[0099] The support switch 160 can include a loop or other fixture
coupled to a lower portion of the apparatus 102, such as the lower
support resting unit 124 for coupling a switch (not shown, such as
a power switch for operating the power of a powered appliance, for
example, if the load 142 is a vacuum cleaner (not shown)). The one
or more accessory supports 162 can include one or more grips,
clasps, or other support fixtures for mounting and/or supporting
tools or accessories (such as tools specifically related to the
load 142 (as shown in FIG. 6B) and its application). For example,
the one or more accessory supports 162 can include a series of
loops coupled with, or part of, second support element 116 for
holding instruments such as hand tools, vacuum cleaner tools (e.g.,
crevice tools, brushes, and the like). In another example, these
accessory supports 162 can include pockets or other storage units
for storing these types of accessories.
[0100] FIG. 8A illustrates an isometric front view of the upper
support element illustrated in FIG. 6A. FIG. 8B illustrates a back
view of the upper support element illustrated in FIG. 6A. FIG. 8C
illustrates a top view of the upper support element illustrated in
FIG. 6A. FIG. 8D illustrates a cross-sectional view of the upper
support element illustrated in FIG. 6A taken along section line A-A
of FIG. 8D. These Figures will be described in conjunction with one
another.
[0101] The upper support element 104 can include an upper support
coupling 106, a lower support coupling 122, a multi-axis joint 129,
one or more support guides 164, and a grommet 166. The grommet can
be used in conjunction with the one or more fasteners 154 for
coupling to the upper support element 104. For example, the grommet
166 can include a eyelet or other opening for receiving a coupling
device (not shown) such as a screw, bolt, or the like, for securing
the upper support resting unit 108 (as shown in FIG. 6A) to the
upper support element 104.
[0102] The one or more support guides 164 can include loops,
guides, or other fixtures either formed as part of, or coupled to,
the upper support element 104. For example, the support guides 164
can include a series of eyelet openings in a portion of the upper
support element 104 coupling the first support element 110 (as
shown in FIG. 6A) to the upper support element 104 and coupling the
support connector 114 (as shown in FIG. 6A) to the upper support
element 104. In this example, the first support element 110 and the
support connector 114 (both shown in FIG. 6A) can include one or
more straps, such as elastic or nylon straps, etc., that are guided
through each of the support guides 164.
[0103] In a further example, the one or more support guides 164 can
include rings or loops that are coupled to the upper support
element 104 (such as through sewing, adhesive, or through the use
of a fastener device). Additionally, a support guide 164 can be
employed as a handle or carry for the first support apparatus 102
(as shown in FIG. 6A). An example of this embodiment is
specifically shown in FIG. 8A. In this example, the support guide
164 can include a larger opening (although not necessarily though)
than the other support guides used to couple the upper support
element 104 to the first support element 110 and the support
connector 114 (both shown in FIG. 6A). In addition to being
employed as a handle or a carry, this support guide 164 can be
additionally used as a guide for the first support elements 110 (as
shown in FIG. 6A) to provide additional support for the operator
(not shown).
[0104] The detailed features set forth in FIG. 8D illustrate an
embodiment of the upper support element 104 where the multi-axis
joint 129 is a ball-and-socket joint. In this example, the
multi-axis joint 129 can be coupled to the upper support coupling
106 and the lower support coupling 122, in which the latter can be
coupled to the lower load connector 28 (for example, shown in FIG.
1). In this configuration, the multi-axis joint 129 can rotate
about three axes (as further illustrated and described above in
conjunction with FIGS. 5A-5C).
[0105] Throughout the disclosure, various elements are described as
being adapted to bear at least a portion of the load 42 (as shown
in FIG. 4 for example). The portions of the load 42 supported as
described above can be divided into weight components along both
the horizontal and vertical axes for each of the load-bearing
support elements described above. Referring specifically to FIG. 1,
and in an exemplary and non-limiting illustrative embodiment, the
lower support element 20 can support the majority of the weight
along the vertical axis and a minority of the weight (or, none of
the weight) along the horizontal axis while the first support
element 10 can bear the minority of the weight (or none of the
weight) along the vertical axis and a majority of the weight along
the horizontal axis.
[0106] Other combinations of weight distribution through the load's
42 (as shown in FIG. 4) weight force vectors' horizontal and
vertical components are contemplated as well for each of the
support elements described above. Furthermore, the vertical axis
can be broadly interpreted to include the Z-axis, and the
horizontal axis can be broadly interpreted to include the X- and/or
Y-axes, as illustrated in FIGS. 5A-5C above.
[0107] The term "coupled," "coupling," "coupler," and like terms
are used broadly herein and can include any method or device for
securing, binding, bonding, fastening, attaching, joining,
inserting therein, forming thereon or therein, or otherwise
associating, for example, mechanically, magnetically, electrically,
chemically, operably, directly or indirectly with intermediate
elements, one or more pieces of members together and can further
include without limitation integrally forming one functional member
with another in a unitary fashion. The coupling can occur in any
direction, including rotationally.
[0108] The order of steps can occur in a variety of sequences
unless otherwise specifically limited. The various steps described
herein can be combined with other steps, interlineated with the
stated steps, and/or split into multiple steps. Similarly, elements
have been described functionally and can be embodied as separate
components or can be combined into components having multiple
functions.
[0109] In some alternate implementations, the embodiments noted in
the figures can occur out of the order noted in the illustrations.
For example, two or more embodiments or aspects of the various
embodiments may be combined in a manner to provide an apparatus not
specifically illustrated in the Figures or detailed in the
description. Therefore, though not explicitly illustrated in the
figures, any and all combinations or sub-combinations of aspects
illustrated in the Figures or described in the detailed description
provided herein, can be performed in any order, with or without
regard for performing the other recited steps.
[0110] Those of skill in the art should, in light of the present
disclosure, appreciate that many changes can be made in the
specific embodiments which are disclosed and still obtain a like or
similar result without departing from the scope of the
invention.
[0111] The inventions have been described in the context of
preferred and other embodiments and not every embodiment of the
invention has been described. Obvious modifications and alterations
to the described embodiments are available to those of ordinary
skill in the art. The disclosed and undisclosed embodiments are not
intended to limit or restrict the scope or applicability of the
invention conceived of by the Applicants, but rather, in conformity
with the patent laws, Applicants intend to fully protect all such
modifications and improvements that come within the scope or range
of equivalent of the following claims.
