DETAILED DESCRIPTION OF THE DRAWINGS
[0026] Illustrative embodiments provide various fatigue reduction
devices and methods of manufacture and utilization. The fatigue
reduction device may be a stand-alone device or may be integrated
with other devices, such as infant carriers, bags, coolers,
luggage, or so forth. As used herein, infant carriers, bags,
coolers, luggage, equipment, or other carried objects that may or
may not include handles, straps, or other carrying mechanisms may
be referred to herein as carriers or objects. The fatigue reduction
device may also be referred to as a forearm carrier, an elbow
carrier, a carrying assistant, or so forth. The fatigue reduction
device may secure carriers of any size, shape, or configuration to
reduce fatigue, decrease comfort, and increase convenience for a
user holding, supporting, or carrying the carrier utilizing the
fatigue reduction device.
[0027] The fatigue reduction device may be configured to secure or
receive straps or handles of the carrier referred to herein as a
handle or object. Extensions from the frame of the fatigue
reduction device may be utilized to secure the object when utilized
horizontally, vertically, or at an angle. The handle or straps may
be actively received by the fatigue reduction device (e.g. between
the frame and extensions) utilizing a clip, clamp, Velcro straps,
slide-in attachment, or other attachment mechanisms. In another
embodiment, the fatigue reduction device may passively secure the
handle or straps during utilization based on gravity and applied
pressure. The fatigue reduction device may include extensions for
keeping the straps or handle in place during utilization. For
example, fully or partially surrounding extensions in the form of
in the form of protrusions, grips, semi-circles, or circular
extensions may secure the straps or handle.
[0028] A portion of the exterior of the fatigue reduction device or
user-faceable portion in contact with the arm of a user may be
curved to conform to the shape of an arm of the user. For example,
a user contact side of the fatigue reduction device may be
concavely shaped to ergonomically fit a portion of the forearm,
elbow (crook), and bicep of the user. The curved shape of the
exterior of the fatigue reduction device provides additional
stability while in use. The exterior or curved portion of the
fatigue reduction device that comes in contact with the body of the
user may be padded to provide additional comfort to the user as the
carrier is carried. In one embodiment, the fatigue reduction device
is formed of high-strength plastics with co-molded, integrated, or
externally attached padding or cover, such as foam, rubber, or
neoprene providing additional padding. In another embodiment, the
fatigue reduction device may be composed of thermoplastic,
thermosetting plastic materials, wood, metal, polymers, etc. In a
further embodiment, the fatigue reduction device may include straps
to wrap around the arm of the user to provide additional
stabilization and support, and to further assist in preventing the
fatigue reduction device from slipping off the arm of the user
during use. The straps may be connected by any temporary fastening
device, such as Velcro, snaps, clasps, buttons, or magnets that may
provide quick and easy attachment and removal of the device by the
user. The exterior or curved portion of the fatigue reduction
device that comes in contact with the body of the user may also be
lined with a semi-sticky material or Velcro that may temporarily
stick to and/or grip the clothing of a user during use, to further
assist in preventing the fatigue reduction device from slipping off
the arm of the user during use.
[0029] The fatigue reduction device may have any number of shapes
including a reverse seven shape, a flattened u-shaped with widening
legs (substantially trapezoidal), a flat shape, a padded sleeve
shape, oval shape or a substantially triangular shape. However, the
fatigue reduction device may utilize any number of shapes and
configurations. The fatigue reduction device may be rested on a
forearm of the user, tucked into the crook of the user's arm,
fitted around the arm of a user, grasped utilizing a handle, or
attached to another device, component, or body part. For example,
one or more ends, vertices, or other portions of the fatigue
reduction device may include a handle for holding the fatigue
reduction device and moving the carrier. As a result, the fatigue
reduction device may be carried in various positions depending on
the preferences of the user.
[0030] The fatigue reduction device may also include a curved or
hooked end for attaching or hanging the fatigue reduction device
from luggage, a bag, a shoulder, a table, a door, an arm, or other
device or component. The fatigue reduction device may also be
configured to receive or be fitted with a cover or sleeve for
adding additional padding, absorbing sweat and dirt, or for
aesthetics. A sleeve may partially or entirely cover the fatigue
reduction device. For example, the fatigue reduction device may be
used with an infant carrier, and as such, some users may want the
fatigue reduction device to match the look, material, design, or
upholstery of the infant carrier.
[0031] FIG. 1 is a pictorial representation of a fatigue reduction
device 100 in accordance with an illustrative embodiment. In one
embodiment, the fatigue reduction device 100 may have a reverse
seven or L-shape. The fatigue reduction device 100 may include a
frame 102. The frame 102 is the main body of the fatigue reduction
device 100. In one embodiment, the frame 102 is molded from a
single piece of material, such as plastic.
[0032] The frame 102 may include an inward, or concave, curve 104.
The inward curve 104 is shaped to conform to the forearm, elbow,
and bicep of the user. In addition, the entire frame 102 may be
inwardly concave (away from the exterior surface) to provide
additional support, rigidity, and comfort. The depth of the inward
curve 104 may vary between a slight curve and a much deeper curve.
The inward curve 104 may extend along the exterior length of the
frame 102. For example, the inward curve 104 may be arced (inwardly
concave) and extend along a longitudinal axis 105 of the fatigue
reduction device 100. In another embodiment, the inward curve 104
may be trapezoidal or triangular groove that may or may not be
rounded. The frame 102 is the body of the fatigue reduction device
100 that supports and distributes the weight of the object being
carried across portions of the user's arm.
[0033] The frame 102 further defines a corner 106. The corner 106
separates a first portion 108 of the frame 102 from a second
portion 110. In one embodiment, the first portion 108 may be
positioned against the arm (or forearm) of the user, the corner 106
may be positioned against the crook of the user's arm, and the
second portion 110 may be positioned against the bicep or upper arm
of the user. However, the fatigue reduction device 100 may be
utilized or positioned in any number of traditional or
untraditional ways, positions, orientations, or configurations that
are selected or desirable to the user.
[0034] The frame 102 may include extensions 112 and 114. In one
embodiment, the extensions 112 and 114 are an integrated portion of
the frame 102 that actively or passively secure the handle or
object of a carrier. In another embodiment, the extensions 112 and
114 may be separately connected or positioned. For example, the
extensions 112 and 114 may be attached at any number of positions,
slip to different positions, or replaced with alternatively shaped
extensions. The extensions 112 and 114 may be anchor or connection
points for a connector, such as a Velcro strap 116. The extensions
112 and 114 may define slits or openings for receiving the Velcro
strap 116. The Velcro strap 116 may alternatively be replaced by a
band, rope, carabiner, hinged gate, latch, or other connection
component.
[0035] The extensions 112 and 114 may be configured to define a
movement range for a handle of the carrier. For example, the handle
or object may be positioned substantially perpendicular to the
longitudinal axis 105 along a lateral axis 119 of the fatigue
reduction device 100. In one embodiment, the extensions 112 and 114
may allow the handle to rotate slightly for optimal positioning. In
another embodiment, the extensions 112 and 114 may closely abut the
handle providing firmness and stability.
[0036] The fatigue reduction device 100 may include an interior
surface 117 and an exterior surface 118. In one embodiment, the
interior surface 117 of the frame 102 may be formed of
polypropylene. The exterior surface 118 may be formed of a softer
material such as foam, rubber, or a softer plastic. In one
embodiment, the frame 102 may be molded with the exterior surface
118 being subsequently co-molded to provide a softer surface.
Varying portions of the fatigue reduction device 100, such as a
handle or space between the extensions 112 and 114, may be coated
with an anti-slip material or pattern for stabilization.
[0037] FIG. 2 is a pictorial representation of a fatigue reduction
device 200 in accordance with an illustrative embodiment. The
fatigue reduction device 200 may include many of the components and
features of the fatigue reduction device 100 of FIG. 1.
[0038] As previously described, the fatigue reduction device 200
may also be utilized by a user grasping a handle 120 (instead of
being positioned on the forearm of crook of the user's arm). In one
embodiment, the fatigue reduction device 200 may include the handle
120 defined at a first end 121 of the frame 102. The handle 120 may
be cylindrically shaped. In another embodiment, the handle 120 may
be ergonomically shaped to fit the hand and fingers of the user.
For example, the handle 120 may include grooves, finger separators,
spindle shape, narrowing and expanding diameters, and so forth. The
handle 120 may be particularly useful for carrying bags or other
carrying devices with uncomfortable or awkward straps or handles.
The handle 120 may also allow the fatigue reduction device 200 to
be utilized at a different angle and configuration.
[0039] In another embodiment, the handle 120 may be T-shaped (not
shown) including a base that extends from the frame 102 and a
handle connected to or integrated with the base. The T-shaped
handle or portion of the fatigue reduction device 200 may be
configured to be secured by the hand of the user with the base
being positioned between fingers of the user (e.g. between the
middle finger and ring finger) during utilization. The T-shaped
handle may similarly have the inward curve 104 for similarly
conforming to the shape of the user's arm.
[0040] The frame 102 may further define a space 122. The space 122
is an opening or cavity for receiving all or a portion of the
user's hands or fingers. In one embodiment, the portion of the
frame 102 on either side of the space 122 may be thicker that the
rest of the frame to support the weight placed on the fatigue
reduction device 200 when the user is utilizing the handle 120.
[0041] The frame 102 may further curve at a second end 128 to form
a hook 130. The hook 130 and second portion 110 may take any number
of shapes depending on the application (e.g. similar to hanger
shapes, fish hooks, etc). The hook 130 may curve substantially
perpendicular to the second portion 110. In another embodiment, the
hook 130 may curve at an oblique or acute angle to the second
portion 110. The hook 130 may be utilized to hook, set, or connect
the fatigue reduction device 200 on a piece of luggage, seat,
holder, table, door, or other component. The tip of the hook 130
may further curve for facilitating connection to another device or
component. For example, the fatigue reduction device 200 may be
utilized to first carry a duffle bag utilizing an arm of the user
as well as subsequently connecting the duffle bag resting on the
extension 124 to a roller bag utilizing the hook 130. The fatigue
reduction device 200 may be useful for individuals carrying
oversized duffle bags with work, sports, hunting, or camping
equipment. In one embodiment, the fatigue reduction device 200 may
be used while hunting. While hunting, a shotgun or rifle barrel is
often rested inside the crook or elbow of a hunter's arm when not
being fired. The fatigue reduction device 200 of the present
invention may be modified to be used while hunting by removing
strap 116 and extension 126, and further modifying extension 124 to
support the barrel of a shotgun or rifle. The fatigue reduction
device may also be camouflaged in coloration. In another
embodiment, the second portion 110 may be elongated for
facilitating connection to a luggage handle. The distance
separating the extension 126 from the hook 130 may vary based on
application. For example, a greater separation distance may
facilitate more easily connecting the hook 130. In addition, the
curvature of the tip of the hook 130 may vary from a slight curve
to nearly curving all the way back on itself. The hook 130 may also
be utilized to store the fatigue reduction device 200 (and attached
component) when not in use.
[0042] Extensions 124 and 126 of the fatigue reduction device 200
are positioned distinctly for receiving and supporting the handle
of a carrier. In one embodiment, one or more of the extensions 124
and 126 may be inwardly curved toward the second portion 110 for
supporting the carrier when the handle 120 is positioned at the
bottom. The extension 124 may support the handle of the carrier
when the hook 130 is being utilized or when vertically positioned
with the handle 120 at the bottom and the hook 130 at the top. The
depth of the curvature of the extension 124 may vary for
stabilizing the handle against the extension 124.
[0043] FIG. 3 is a pictorial representation of a fatigue reduction
device 300 being utilized with an infant carrier 302 in accordance
with an illustrative embodiment. As shown, the fatigue reduction
device 300 may be carried on the forearm 304, crook 306, and a
bicep 308 of a user 310. The fatigue reduction device 300 may
further distribute the weight associated with the fatigue reduction
device 300.
[0044] The fatigue reduction device 300 may be particularly useful
when carrying the infant carrier 302 over longer distances. The
fatigue reduction device 300 may also be useful for petite users,
the elderly, or those with less strength and endurance. The fatigue
reduction device 300 may connect to a handle 312 of the fatigue
reduction device 300.
[0045] FIG. 4 is a pictorial representation of a fatigue reduction
device 400 integrated with an infant carrier 402 in accordance with
an illustrative embodiment. In one embodiment, the fatigue
reduction device 400 may be fixable or slidably integrated with the
infant carrier 402. For example, a handle 404 may be substantially
semi-circular or U-shaped. The fatigue reduction device 400 may be
slidably attached to the handle 404 to move to either of the
corners or vertices of the U. For example, the fatigue reduction
device 400 may be slid to a bottom portion of the handle 404 for

and a Velcro strap 620.
[0048] The fatigue reduction device 600 may be more easily used for
carrying an object using a left or right arm or from either
direction or user orientation. The extensions 608 and 610 may be
utilized to stabilize the object while being carried. In another
embodiment, the extensions 608 and 610 may fully or partially
encompass the handle of the carrier. For example, the extensions
608 and 610 may further encompass the handle of the carrier by
creating a semi-circular shape extending from the frame 602. In
this example, the extensions 608 and 610 may be pried or forced
open to accept the object. In another embodiment, the Velcro strap
620 may be replaced by a latch or buckle for enclosing the object
between the extensions 608 and 610. The extensions 608 and 610 may
be curved or straight. In one embodiment, the extensions 608 and
610 include a curved structure 621 for naturally guiding the handle
to a middle point of the frame 602 between the extensions 608 and
610.
[0049] In one embodiment, each end or tip of the side faces 614 and
616 may include a hook as previously described for hanging or
supporting the fatigue reduction device 600. As shown, the angle
between the bottom face 612 and side faces 614 and 616 may vary. A
more acute angle may facilitate squeezing the fatigue reduction

[0051] The fatigue reduction device 700 further includes extensions
714 and 716 that are curved and larger for better supporting the
object when the user utilizes the handles 702 and 704. If only one
side of the fatigue reduction device includes a handle, such as
only handle 702, one extension 714 may be larger than the other
extension 716 to lend support to the object when the fatigue
reduction device is positioned vertically.
[0052] Referring now to FIGS. 8-9, a pictorial representation of
another fatigue reduction device 800 in accordance with an
illustrative embodiment is shown. The fatigue reduction device 800
is triangularly shaped for use for more universal usage from
different angles. In various embodiments, the fatigue reduction
device 800 may have an equilateral or isosceles shape and
configuration. An isosceles shape may be more useful for maximizing
the surface area of the fatigue reduction device 800 against the
forearm of the user.
[0053] In one embodiment, the fatigue reduction device 800 may
include a first half 802, a second half 804, a first
user-contactable face 806, a second user-contactable face 808, and
a user-contactable third face 810, a hinge 812, a support 814, a
cavity 816, a curved surface 818, and a cover 820. The first half
802 and second half 804 of the fatigue reduction device 800 may
make up the frame. The first half 802 and second half 804 may be
configured to open and close together around an object. The support
814 may be utilized to abut, support, secure, and/or stabilize the
object. The support 814 at least partially defines the cavity 816
through which the object may pass. The cavity 816 is an opening or
receptacle for receiving the object shown in this embodiment as a
through hole.
[0054] In one embodiment, the support 814 may include protrusions,
ridges, protuberances, or other components for securing the object.
For example, the support 814 may be formed of rubberized ridges
that provide a surface that enhances friction and prevents the free
movement of the object when being carried by the fatigue reduction
device 800. The support 814 may be utilized to ensure that the
fatigue reduction device 800 does not slip or slide easily during
utilization. For example, this may be particularly important when
the fatigue reduction device 800 is being utilized with an infant
carrier loaded with a child. In one embodiment, the support 814 may
be integrated with the first half 802 and the second half 804. In
another embodiment, the support 814 may be separately attached to
the object with the first half 802 and the second half 804
enclosing the support 814. An outer surface of the support 814 in
contact with the first half 802 and the second half 804 may be
spherically shaped for securing the support 814. In a further
embodiment, the triangularly shaped fatigue reduction device 800
may be formed of a flexible plastic or rubber membrane, wherein the
entire device may be inflatable. This particular embodiment would
not comprise hinge 812, first half 802, or second half 804.
Instead, the outside frame of the fatigue reduction device 800 is
continuous and formed of flexible plastic or rubber, while the
inside of the device may be a hollow airtight chamber for holding
air. A user may insert and/or remove air from the fatigue reduction
device 800 by a nozzle included on the frame of the fatigue
reduction device 800. A person of ordinary skill in the art would
recognize that such a nozzle may be similar to those typically used
in personal inflatable devices. After inflation by the user, the
entire fatigue reduction device 800 may be one solid triangular
shaped support system. In place of the hinge 812, a notch is formed
for accessing the cavity 816 and inserting a carrier into the
cavity 816 during use. Notably, the inflatable fatigue reduction
device 800 would be lightweight during use, and easily stored and
transported when not in use after deflation (e.g., in a purse or
pocket).
[0055] The hinge 812 may represent a pivot point of the first half
802 and the second half 804. In one embodiment, the hinge 812 may
represent a small flexible material or fabric connection between
the first half 802 and the second half 804. The hinge 812 may be a
barrel hinge, pivot hinge, continuous hinge, concealed hinge
(self-biased), strap hinge, or other known hinge type. In another
embodiment, the hinge 812 may represent a pin hinge about which the
first half 802 and the second half 804 may pivot or rotate. The
first face 806, the second face 808, and the third face 810 may
similarly include the curved surface 818 to ergonomically fit or
conform to the arm of the user during utilization.
[0056] The cover 820 may cover all or a portion of the fatigue
reduction device 800. In one embodiment, the cover 820 is a padded
band that conforms to the first face 806, the second face 808, and
the third face 810. For example, the cover 820 may be a decorated
neoprene band secured around the periphery of the fatigue reduction
device 800. The cover 820 may also be utilized to further secure
the first half 802 and the second half 804 together. The cover 820
may cover the exterior surfaces of the first face 806, second face
808, and third face 810 as well as side portions of the first half
802 and second half 804.
[0057] In one embodiment, the first half 802 and the second half
804 may include a buckle, elastic, latch, tie off, or other
mechanism (not shown) for securing the first half 802 and the
second half 804 around the object. As shown, the first half 802 and
the second half 804 may define cutouts 822 for receiving the
support 814.
[0058] In one embodiment, the cover 820 may be configured to cover
the entire fatigue reduction device 800. The cover 820 may include
a zipper, button, or other fasteners for being secured to or around
the fatigue reduction device 800. The cover 820 may also be
specifically sized to fit the fatigue reduction device 800. The
cover 820 may provide a functional and decorative function. The
cover 820 may include a pattern or decorations that are user
selected and that may match or correspond to an object being
carried or an intended usage of the cover 820. In one embodiment,
the cover 820 is padded.

comprise padding inside the elbow (e.g., the crook of the arm)
and/or along a supinated side of a forearm of the user to support
and distribute the weight of an object being carried across
portions of the user's arm. The padding has a surface adapted to
contact the user's arm, the surface having an area greater than the
portion of the object rested on the user's arm. This padding may
comprise high-strength flexible and/or semi-rigid plastics with
co-molded, integrated, or additional padding, such as foam, rubber,
or neoprene. This specific embodiment would be inconspicuous as it
would allow a user to wear the fatigue reduction device under
clothing. Furthermore, the device would not necessarily have to be
removed when not in use, as the device would be lightweight,
flexible and allow normal movement/range of motion of the arm.
[0074] METHOD OF USE: The fatigue reduction device may be utilized
in any number of methods. In one embodiment, the process may begin
by attaching the fatigue reduction device to an object to be
carried. In one embodiment, the object is a strap or handle with
the load being carried below the fatigue reduction device. In

arm and a buckle. The fatigue reduction device may also secure the
object utilizing flexible or semi-rigid extensions that apply
forces to the object.
[0075] In another embodiment, the fatigue reduction device may be
an integrated portion of the object. For example, an infant carrier
may include one or more fatigue reduction devices positioned along
a handle. In one embodiment, the fatigue reduction device may be
configured to be unfolded or expanded to form the shapes and
configurations herein shown. For example, the fatigue reduction
device may include cut-outs for the extensions and hinges at the
corners that allow the fatigue reduction device to be folded in on
itself. The fatigue reduction device may be slidably attached to
the object allowing it to be positioned for use and then positioned
for storage (out of the way) when not in use. For example, the
fatigue reduction device may be slid into a receptacle, retracted,
or collapsed when not in use.
[0076] The object may be tightly or loosely secured depending on
the application and the user preferences. For example, some
movement may be desirable to allow the fatigue reduction device to
be positioned against the arm of the user wall securing the object
at a desired angle. In another embodiment, the fatigue reduction
device may be specifically configured to receive the object, such
as a particular brand and model of infant carrier, laptop bag, book
bag, purse, or a particular type of duffle bag.
[0077] In another embodiment, the object may be positioned on or
rest on the fatigue reduction device. For example, the object may
be simply positioned over the fatigue reduction device and held in
place by gravity when utilized by the user.
[0078] Next, the fatigue reduction device is positioned on a user.
In one embodiment, the fatigue reduction device is positioned on or
against the arm of the user. The fatigue reduction device may be
rested on the arm of the user. In one embodiment, the fatigue
reduction device is positioned on the forearm of the user against
the crook of the user's arm. In another embodiment, the fatigue
reduction device may be positioned against another appendage or
body part. In one embodiment, the fatigue reduction device may
include one or more straps for securing the fatigue reduction
device to the arm of the user. The fatigue reduction device may be
long enough that the user may both position the fatigue reduction
device in the crook of the user's arm and hold onto a handle of the
fatigue reduction device utilizing the same arm.
[0079] Method of Manufacture
[0080] In one embodiment, the fatigue reduction device may be
molded (injection molding, compression molding, and so forth as are
known in the art). For example, the raw materials, such as plastic
or polymer pellets may be heated and injected into a mold or die.
The mold is configured to have any of the shapes and configurations
(or a combination thereof) as are herein shown or described. Next,
the fatigue reduction device is removed from the mold once
substantially cooled. The fatigue reduction device may be sanded or
otherwise smoothed to remove any seams or imperfections.
[0081] In another embodiment, the fatigue reduction device may be
generated by utilizing a three dimensional printing process. A
three-dimensional model of any of the described embodiments or any

print the fatigue reduction device. In one embodiment, the fatigue
reduction device may be printed using a first rigid material and
then a softer padded material may be printed on an exterior portion
of the fatigue reduction device that comes in contact with the body
of the user.
[0082] In one embodiment, the fatigue reduction device may be
extended. For example, the frame 102 of FIG. 1 may be extended
utilizing any of rails, latches and teeth, biased pins and holes,
an overlapping frame or so forth. In addition, the angle of the
corner portions may be rigid, flexible, or adjustable.
[0083] In one embodiment, the fatigue reduction device may extend
along an entire length of the arm between the elbow and hand. The
fatigue reduction device may be configured to receive any number of
additional components. In one embodiment, the fatigue reduction
device may not include extensions, such as extensions 112 and 114
(and including strap 116). Instead, the fatigue reduction device
may be elongated including a handle and attachment mechanisms for
receiving a tray, plate, or other component on the interior surface
117. The attachment mechanisms may include Clips, bindings, Velcro,
or straps to secure the tray or other component. For example, the
fatigue reduction device may be configured to receive a beverage
serving tray as are utilized by airlines to serve drinks. As a
result, the user may rest the fatigue reduction device on one arm
securing the fatigue reduction device and attached tray between the
bicep (second portion 110) and hand of the user (a handle 120 that
is part of the elongated frame). The fatigue reduction device may
provide for added stability, decreased hand fatigue, and easier
access to the tray utilizing the user's other arm.
[0084] In one embodiment, the fatigue reduction device may include
one or more hooks or extensions for securing other components. The
fatigue reduction device may include hooks (e.g. J-hooks) or
extensions on a left side and right side of the fatigue reduction
device (when positioned on the user's arm) for holding bags (paper,
plastic, reusable, recyclable, etc). As a result, the fatigue
reduction device may be utilized when shopping at a mall, grocery
store, outlet stores, or flea market to facilitate a user in
carrying goods and providing different methods of carrying the
goods (e.g. carried in the crook of the user's arm, utilizing a
more defined handle provided by the fatigue reduction device). The
fatigue reduction device may include any configuration of
extensions, hooks, or structure of the fatigue reduction device to
secure objects laterally or parallel to the longitudinal axis of
the fatigue reduction device. For example, fatigue reduction device
may allow shopping bags to be connected on a left and right side of
a user's arm (when positioned on the user's forearm or in the crook
of the user's arm).
[0085] In one embodiment, the fatigue reduction device may include
a lanyard for attachment to any number of devices. For example, a
lanyard may be utilized with a retracting cord connected to a base
to secure the fatigue reduction device when not in use and so that
it is not lost. The base may include a clip, suction cup, or clamp
for attaching the fatigue reduction device to a purse, infant
carrier, luggage, or other component.
[0086] In another embodiment, the angle of the handle of the
fatigue reduction device may vary or be adjustable for adjusting
the user's grip. Various angles and portions of the fatigue
reduction device may be reconfigured, manipulated, or shaped to
best fit the user. In addition, the fatigue reduction device may be
carried in any number of positions.
[0087] In another embodiment, the fatigue reduction device may have
a substantially tear drop shape (i.e. the side view of the
profile). The end of the tear drop shape may be rounded. In one
embodiment, the tear drop shape may include an integrated handle as
is herein described.
[0088] The illustrative embodiments provide a fatigue reduction
device that allows a user to carry an object, goods, carrier, or a
load for longer periods of time without being worn out. In
addition, arm and hand fatigue and soreness may be reduced. The
fatigue reduction device may be particularly useful for users doing
extended carrying (i.e. parks, airports, etc), users with limited
strength, petite users, disabled users, and so forth. The fatigue
reduction device may allow a user to have access to an ergonomic
handle in situations where a handle may be beneficial, convenient,
comfortable, or desirable. The fatigue reduction device provides
multiple modes and methods for carrying objects that are adaptable
to the needs of the user.
