Description
BACKGROUND
[0001] The present embodiments relate generally to articles of
footwear and including coverable motorized adjustment systems.
[0002] Articles of footwear generally include two primary elements:
an upper and a sole structure. The upper is often formed from a
plurality of material elements (e.g., textiles, polymer sheet
layers, foam layers, leather, synthetic leather) that are stitched
or adhesively bonded together to form a void on the interior of the
footwear for comfortably and securely receiving a foot. More
particularly, the upper forms a structure that extends over instep
and toe areas of the foot, along medial and lateral sides of the
foot, and around a heel area of the foot. The upper may also
incorporate a lacing system to adjust the fit of the footwear, as
well as permitting entry and removal of the foot from the void
within the upper.
[0003] In some cases, the lacing system may include a motorized
tensioning system. Components of a motorized tensioning system may
include, for example, a motorized tightening device, a control
board, and a battery. Each of these components may be incorporated
into an article of footwear in various places. In some cases, these
components may be mounted on an outer portion of the footwear
upper. In such configurations, it may be desirable to celebrate the
inclusion of these components on the footwear while concealing
their outward appearance and protecting these components from
damage.
SUMMARY
[0004] In some embodiments, the disclosed footwear may include
individual covers configured to cover lace tensioning system
components on the outer surface of the footwear upper. Such covers
may include faceted surfaces configured to define a contoured
cavity enclosing the tensioning system components.
[0005] In one aspect, the present disclosure is directed to an
article of footwear, including a motorized tensioning system
including a tensile member and a motorized tightening device
attached to an outer surface of the article of footwear, the
tightening device configured to apply tension in the tensile member
to adjust the size of an internal void defined by the article of
footwear. The article of footwear may also include a tightening
device cover configured to be removably attached to the article of
footwear over the tightening device.
[0006] In another aspect, the present disclosure is directed to a

DETAILED DESCRIPTION
[0022] To assist and clarify the subsequent description of various
embodiments, various terms are defined herein. Unless otherwise
indicated, the following definitions apply throughout this
specification (including the claims). For consistency and
convenience, directional adjectives are employed throughout this
detailed description corresponding to the illustrated
embodiments.
[0023] The term "longitudinal," as used throughout this detailed
description and in the claims, refers to a direction extending a
length of a component. For example, a longitudinal direction of an
article of footwear extends from a forefoot region to a heel region
of the article of footwear. The term "forward" is used to refer to
the general direction in which the toes of a foot point, and the
term "rearward" is used to refer to the opposite direction, i.e.,
the direction in which the heel of the foot is facing.
[0024] The term "lateral direction," as used throughout this
detailed description and in the claims, refers to a side-to-side
direction extending a width of a component. In other words, the
lateral direction may extend between a medial side and a lateral
side of an article of footwear, with the lateral side of the
article of footwear being the surface that faces away from the
other foot, and the medial side being the surface that faces toward
the other foot.
[0025] The term "side," as used in this specification and in the
claims, refers to any portion of a component facing generally in a
lateral, medial, forward, or rearward direction, as opposed to an
upward or downward direction.
[0026] The term "vertical," as used throughout this detailed
description and in the claims, refers to a direction generally
perpendicular to both the lateral and longitudinal directions. For
example, in cases where a sole is planted flat on a ground surface,
the vertical direction may extend from the ground surface upward.
It will be understood that each of these directional adjectives may
be applied to individual components of a sole. The term "upward"
refers to the vertical direction heading away from a ground
surface, while the term "downward" refers to the vertical direction
heading towards the ground surface. Similarly, the terms "top,"
"upper," and other similar terms refer to the portion of an object
substantially furthest from the ground in a vertical direction, and
the terms "bottom," "lower," and other similar terms refer to the
portion of an object substantially closest to the ground in a
vertical direction.
[0027] The "interior" of a shoe refers to space that is occupied by
a wearer's foot when the shoe is worn. The "inner side" of a panel
or other shoe element refers to the face of that panel or element
that is (or will be) oriented toward the shoe interior in a
completed shoe. The "outer side" or "exterior" of an element refers
to the face of that element that is (or will be) oriented away from
the shoe interior in the completed shoe. In some cases, the inner
side of an element may have other elements between that inner side
and the interior in the completed shoe. Similarly, an outer side of
an element may have other elements between that outer side and the
space external to the completed shoe. Further, the terms "inward"
and "inwardly" shall refer to the direction toward the interior of
the shoe, and the terms "outward" and "outwardly" shall refer to
the direction toward the exterior of the shoe.
[0028] For purposes of this disclosure, the foregoing directional
terms, when used in reference to an article of footwear, shall
refer to the article of footwear when sitting in an upright
position, with the sole facing groundward, that is, as it would be
positioned when worn by a wearer standing on a substantially level
surface.
[0029] In addition, for purposes of this disclosure, the term
"fixedly attached" shall refer to two components joined in a manner
such that the components may not be readily separated (for example,
without destroying one or both of the components). Exemplary
modalities of fixed attachment may include joining with permanent
adhesive, rivets, stitches, nails, staples, welding or other
thermal bonding, or other joining techniques. In addition, two
components may be "fixedly attached" by virtue of being integrally
formed, for example, in a molding process.
[0030] For purposes of this disclosure, the term "removably
attached" shall refer to the joining of two components in a manner
such that the two components are secured together, but may be
readily detached from one another. Examples of removable attachment
mechanisms may include hook and loop fasteners, friction fit
connections, interference fit connections, threaded connectors,
cam-locking connectors, and other such readily detachable
connectors.
[0031] A motorized footwear lacing system may include an article of
footwear and a motorized tensioning system. The motorized
tensioning system may include a tensile member and a motorized
tightening device. In some embodiments, the lacing system may be
provided as a kit of parts, including a container in which a pair
of footwear, a pair of motorized tensioning systems, and a remote
device may be provided. The tensile member may include a cord or
other lace-like member that attaches to the motorized tightening
device. In some embodiments, the cord may be laced through lace
receiving members in a lacing region of the article of footwear. In
some embodiments, the footwear may include one or more removable
covers configured to be removably attached to the upper of the
article of footwear over the components of the tensioning
system.
[0032] The motorized tensioning system enables relatively rapid
tightening of the footwear. In addition, in some embodiments the
tightening system may provide incremental tightening. Such
incremental tightening may enable the user to achieve a predictable
tightness for each wearing. In some embodiments, sensors may be
included to monitor tightness. In such embodiments, the user may
also achieve a predictable tightness.
[0033] In some cases, using a motorized tightening device may
remove dexterity issues that may occur with other tensioning
technologies (pulling straps, Velcro, and other such manual closure
systems). Such a design could improve the use of footwear for
physically impaired or injured individuals who may otherwise have a
hard time putting on and adjusting their footwear. Using the
designs proposed here, footwear could be tightened via a push
button or remote interface.
[0034] In some embodiments, the tensioning system may be remotely
controlled, for example by a bracelet or hand-held device, such as
a mobile phone. In such embodiments, adjustments may be made
without the wearer having to stop the activity in which they are
participating. For example, a distance runner may adjust the
tightness of their footwear without interrupting their workout or
competitive event to bend over and adjust their footwear manually
or by pressing buttons on the footwear to activate the motorized
tensioning system.
[0035] In addition, the tensioning system may also be configured to
make automatic adjustments. For example, using tightness sensors,
the system may be configured to maintain tightness during wear by
adjusting tightness according to changes in the fit. For example,
as feet swell during wear, the tensioning system may release
tension on the tensile member, in order to maintain the initially
selected tightness.
[0036] Further, the tensioning system may be configured to adjust
the tightness during use to improve performance. For example, as a
wearer places loads on the footwear during an athletic activity,
the system may tighten or loosen the tensile members to achieve
desired performance characteristics. For example, as a runner
proceeds around a curve, the tensioning system may tighten the
footwear in order to provide additional stability and maintain the
foot in a centralized position within the footwear. As another
example, when a runner is running downhill, the tightening system
may loosen the footwear to limit additional forces exerted on the
foot as the foot tends to slide toward the front of the footwear
during the downhill run. Numerous other automated adjustments may
be utilized for performance. Such automated adjustments may vary
for each activity. In addition, the type and amount of such
adjustments may be preselected by the user. For instance, using the
examples above, the user may select whether to tighten or loosen
the footwear while proceeding around a curve. In addition, the user
may select whether to utilize an automated adjustment at all during
certain conditions. For example, the user may choose to implement
the adjustment while proceeding around curves, but may opt not to
utilize an adjustment when running downhill.
[0037] FIG. 1 shows a motorized footwear lacing system 100. As
shown in FIG. 1, system 100 may include an article of footwear 105.
FIG. 1 shows a partial rear perspective view of footwear 105, the
forefoot portion of which has been truncated for purposes of
illustration. Footwear 105 may be any of a variety of footwear
types, including athletic footwear, such as running shoes,
basketball shoes, soccer shoes, cross-training shoes, baseball
shoes, football shoes, and golf shoes, for example. In other
embodiments, footwear 105 may be another type of footwear
including, but not limited to, hiking boots, casual footwear, such
as dress shoes, as well as any other kinds of footwear.
Accordingly, the disclosed concepts may be applicable to a wide
variety of footwear types.
[0038] As shown in FIG. 1, footwear 105 may include an upper 110
and a sole structure 115 secured to upper 110. Upper 110 may
include one or more material elements (for example, meshes,
textiles, foam, leather, and synthetic leather), which may be
joined to define an interior void 135 configured to receive a foot
of a wearer. The material elements may be selected and arranged to
selectively impart properties such as light weight, durability,
air-permeability, wear-resistance, flexibility, and comfort. Upper
110 may define a throat opening 140 through which a foot of a
wearer may be received into void 135.
[0039] Sole structure 115 may be fixedly attached to upper 110 (for
example, with adhesive, stitching, welding, or other suitable
techniques) and may have a configuration that extends between upper
110 and the ground. Sole structure 115 may include provisions for
attenuating ground reaction forces (that is, cushioning and
stabilizing the foot during vertical and horizontal loading). In
addition, sole structure 115 may be configured to provide traction,
impart stability, and control or limit various foot motions, such
as pronation, supination, or other motions.
[0040] The configuration of sole structure 115 may vary
significantly according to one or more types of ground surfaces on
which sole structure 115 may be used. For example, the disclosed
concepts may be applicable to footwear configured for use on any of
a variety of surfaces, including indoor surfaces or outdoor
surfaces. The configuration of sole structure 115 may vary based on
the properties and conditions of the surfaces on which footwear 105
is anticipated to be used. For example, sole structure 115 may vary
depending on whether the surface is harder or softer. In addition,
sole structure 115 may be tailored for use in wet or dry
conditions.
[0041] Upper 110 may also form a lacing region 130. In some
embodiments, lacing region 130 may be disposed in an instep region
of footwear 105, as shown in FIG. 1. In other embodiments, the
lacing region may be disposed on other portions of the footwear,
such as the medial and/or lateral sides of the footwear. As further
shown in FIG. 1, footwear 105 may include a plurality of lace
receiving members 125 in lacing region 130. Lace receiving members
125 may be configured to receive a lace or tensile member for
adjusting the fit of footwear 105.
[0042] The arrangement of lace receiving members 125 in this
embodiment is only intended to be exemplary and it will be
understood that other embodiments are not limited to a particular
configuration for lace receiving members 125. Furthermore, the
particular types of lace receiving members 125 illustrated in the
embodiments are also exemplary and other embodiments may
incorporate any other kinds of lace receiving members or similar
lacing provisions. In some other embodiments, for example, footwear
105 may include traditional eyelets. Some examples of lace guiding
provisions that may be incorporated into the embodiments are
disclosed in Cotterman et al., U.S. Patent Application Publication
Number 2012/0000091, published Jan. 5, 2012 and entitled "Lace
Guide," the disclosure of which is incorporated herein by reference
in its entirety. Additional examples are disclosed in Goodman et
al., U.S. Patent Application Publication Number 2011/0266384,
published Nov. 3, 2011 and entitled "Reel Based Lacing System" (the
"Reel Based Lacing Application"), the disclosure of which is
incorporated herein by reference in its entirety. Still additional
examples of lace receiving members are disclosed in Kerns et al.,
U.S. Patent Application Publication Number 2011/0225843, published
Sep. 22, 2011 and entitled "Guides For Lacing Systems," the
disclosure of which is incorporated herein by reference in its
entirety.
[0043] Footwear 105 may also be configured with a motorized
tensioning system 145. Tensioning system 145 may comprise various
components and systems for adjusting the size of opening 140 and
thereby tightening (or loosening) upper 110 around a wearer's foot.
In some embodiments, tensioning system 145 may comprise a tensile
member 120 and a motorized tightening device 150 configured to
apply tension in tensile member 120. In some embodiments,
tightening device 150 may be attached to an outer surface of
footwear 105. For example, as shown in FIG. 1, in some embodiments,
tightening device 150 may be attached to an outer surface 111 of
upper 110.
[0044] Tightening device 150 may be configured to apply tension in
tensile member 120 to adjust the size of internal void 135 defined
by footwear 105. In some embodiments, tightening device 150 may
include provisions for winding and unwinding portions of tensile
member 120. Tightening device may include a motor. In some
embodiments, the motor may be an electric motor. However, in other
embodiments, the motor could comprise any kind of non-electric
motor known in the art. Examples of different motors that can be
used include, but are not limited to: DC motors (such as
permanent-magnet motors, brushed DC motors, brushless DC motors,
switched reluctance motors, etc.), AC motors (such as motors with
sliding rotors, synchronous electrical motors, asynchronous
electrical motors, induction motors, etc.), universal motors,
stepper motors, piezoelectric motors, as well as any other kinds of
motors known in the art.
[0045] Tensile member 120 may be configured to pass through various
different lace receiving members 125 in lacing region 130. In some
cases, lace receiving members 125 may provide a similar function to
traditional eyelets on uppers. In particular, as tensile member 120
is pulled or tensioned, throat opening 140 may generally constrict
so that upper 110 is tightened around a foot.
[0046] Tensile member 120 may comprise any type of type of lacing
material known in the art. Examples of lace that may be used
include cables or fibers having a low modulus of elasticity as well
as a high tensile strength. A lace may comprise a single strand of
material, or can comprise multiple strands of material. An
exemplary material for the lace is SPECTRA.TM., manufactured by
Honeywell of Morris Township NJ, although other kinds of extended
chain, high modulus polyethylene fiber materials can also be used
as a lace. Still further exemplary properties of a lace can be
found in the Reel Based Lacing Application mentioned above. The
term "tensile member," as used throughout this detailed description
and in the claims, refers to any component that has a generally
elongated shape and high tensile strength. In some cases, a tensile
member could also have a generally low elasticity. Examples of
different tensile members include, but are not limited to: laces,
cables, straps and cords. In some cases, tensile members may be
used to fasten and/or tighten an article footwear.
[0047] In some embodiments, tensile member 120 may be provided in
sections. For example, tensile member 120 may include a first
tensile member portion 170. In addition, tensile member 120 may
include a second tensile member portion 175. Also, tensile member
120 may include a third tensile member portion 176. Third tensile
member portion 176 may be laced into footwear 105 through lace
receiving members 125. First tensile member portion 170 and second
tensile member portion 175 may be releasably fastened to third
tensile member portion 176. For example, in some embodiments,
tensile member 120 may include one or more quick release couplings
180, by which first tensile member portion 170, second tensile
member portion 175, and third tensile member portion 176 may be
releasably joined. Without first tensile member portion 170 and
second tensile member portion 175 attached, third tensile member
portion 176 may be used as, or be replaced by, a manual (i.e.,
traditional) shoelace.
[0048] Couplings 180 may be readily decoupled manually, in order to
enable removal of tensile member 120 from the article of footwear.
Such manual decoupling may facilitate removal of the motorized
tensioning system from footwear 105. This manual release mechanism
may also enable the tension in the tensile member to be released in
the event of a malfunction or low battery power. Exemplary manual
release mechanisms may include any suitable connector types. In
some embodiments, threaded connections may be utilized. In other
embodiments the tensile member could utilize any other fastening
provisions including a snap fit connector, a hook and receiver type
connector, or any other kinds of manual fasteners known in the
art.
[0049] In some embodiments, tensile member 120 may be passed
through lace receiving members 125 and may pass through internal
channels within upper 110, between lacing region and tightening
device 150, as shown in FIG. 1. In some embodiments, the internal
channels may extend around the sides of upper 110 and guide tensile
member 120 towards motorized tightening device 150, which may be
mounted on a heel portion of upper 110, as shown in FIG. 1. In some
cases, motorized tightening device 150 may include provisions for
receiving portions of tensile member 120. For example, in some
cases, end portions of tensile member 120 may pass through
apertures in a housing unit of motorized tightening device 150.
[0050] As further shown in FIG. 1, tensioning system 145 may also
include a control unit 155 configured to control the operation of
tightening device 150. In some embodiments, control unit 155 may be
attached to the outer surface of footwear, such as outer surface
111 of upper 110. Control unit 155 may include various circuitry
components. In addition, control unit 155 may include a processor,
configured to control motorized tightening device 150.
[0051] Control unit 155 shown in FIG. 1 is only intended as a
schematic representation of one or more control technologies that
could be used with tightening device 150. For example, there are
various approaches to motor control that may be employed to allow
speed and direction control. For some embodiments, a
microcontroller unit may be used. The microcontroller may use
internal interrupt generated timing pulses to create pulse-width
modulation (PWM) output. This PWM output is fed to an H-bridge
which allows high current PWM pulses to drive the motor both
clockwise and counterclockwise with speed control. However, any
other methods of motor control known in the art could also be
used.
[0052] Tensioning system 145 may also include a power source 160
configured to supply power to motorized tightening device 150. In
some embodiments, power source 160 may include one or more
batteries. Power source 160 shown in FIG. 1 is only intended as a
schematic representation of one or more types of battery
technologies that could be used to power motorized tightening
device 150. One possibly battery technology that could be used is a
lithium polymer battery. The battery (or batteries) could be
rechargeable or replaceable units packaged as flat, cylindrical, or
coin shaped. In addition, batteries could be single cell or cells
in series or parallel.
[0053] Rechargeable batteries could be recharged in place or
removed from an article for recharging. In some embodiments,
charging circuitry could be built in and on board. In other
embodiments, charging circuitry could be located in a remote
charger. In another embodiment, inductive charging could be used
for charging one or more batteries. For example, a charging antenna
could be disposed in a sole structure of an article and the article
could then be placed on a charging mat to recharge the
batteries.
[0054] Additional provisions could be incorporated to maximize
battery power and/or otherwise improve use. For example, it is also
contemplated that batteries could be used in combination with super
caps to handle peak current requirements. In other embodiments,
energy harvesting techniques could be incorporated which utilize
the weight of the runner and each step to generate power for
charging a battery.
[0055] As shown in FIG. 1, tensioning system 145 may include one or
more electrical cables 165 extending between components of system
145. Electrical cables 165 may be configured to deliver electrical
power, as well as electronic communication signals, between power
source 160, tightening device 150, and control unit 155. In some
embodiments, such electrical cables may be disposed under at least
one layer of upper 110.
[0056] In some embodiments, one or more components of tensioning
system 145 may be removable from footwear 105. Providing motorized
tensioning system 145 as removable from footwear 105 may enable
footwear 105 to be used conventionally. In addition, removability
of tensioning system 145 may enable components of tensioning system
145 to be repaired or replaced independent of footwear 145. In
addition, removability of tensioning system 145 enables footwear
145 to be repaired or replaced independent of tensioning system
145.
[0057] Provisions for mounting components of tensioning system 145
to outer surface 111 of upper 110 can vary in different
embodiments. In some cases, motorized tightening device 150 may be
removably attached, so that motorized tensioning system 145 can be
easily removed by a user and modified (for example, when tensile
member 120 must be replaced). For example, in some embodiments,
components of tensioning system 145 may be removably attached to
footwear 105 with a hook and loop fastener material. In other
embodiments, components of tensioning system 145 may be removably
attached to footwear 105 with a tongue and groove configuration.
Further, in some embodiments, components of tensioning system 145
may be removably attached to footwear 105 with an interference fit
or friction fit. The components of such a friction fit attachment
may have any suitable orientation. Alternative types of removable
connections are also possible including, for example, threaded
fasteners, cam-lock fasteners, spring clip type fasteners, and
other removable connection mechanisms.
[0058] As shown in FIG. 1, tightening device 150 may be configured
to be removably attached to a heel portion of footwear 105. For
example, as shown in FIG. 1, in some embodiments, tightening device
150 may be removably attached to outer surface 111 of upper 110 in
a rearmost portion of footwear 105. This positioning may facilitate
the application of tension to tensile members on both a medial side
and a lateral side of footwear 110.
[0059] In other embodiments, however, any of these components could
be disposed in any other portions of an article, including the
upper and/or sole structure. In some cases, some components could
be disposed in one portion of an article and other components could
be disposed in another, different, portion. The location of a
motorized tightening device can vary from one embodiment to
another. The illustrated embodiments show a motorized tightening
device disposed on the heel of an upper. However, other embodiments
may incorporate a motorized tightening device in any other location
of an article of footwear, including the forefoot and midfoot
portions of an upper. In still other embodiments, a motorized
tightening device could be disposed in a sole structure of an
article. The location of a motorized tightening device may be
selected according to various factors including, but not limited
to: size constraints, manufacturing constraints, aesthetic
preferences, optimal lacing placement, ease of removability as well
as possibly other factors.
[0060] In another embodiment motorized tightening device 150 could
be disposed at the heel of an upper, while power source 160 and/or
control unit 155 could be disposed with a sole structure of
footwear 110. For example, in one embodiment the power source and
control unit may be disposed under midfoot region of footwear 105
with a cable connection (or a simple electrical contact connection)
to motorized tightening device 150, which may be disposed in the
heel region of footwear 105. In still other embodiments, a power
source and a control unit could be integrated into the motorized
tightening device. For example, in some embodiments, both a battery
and a control unit could be disposed within an outer housing of
motorized tightening device 150.
[0061] Further, in some embodiments, the locations of tightening
device 150, control unit 155, and power source 160 may be
rearranged. Control unit 155 is shown in the left side of footwear
105 in FIG. 1. Power source 160 is shown on the right side of
footwear 105. The positions of control unit 155 and power source
160 may be reversed in some embodiments. However, it may be
advantageous to locate the thinner component on the medial side of
footwear 105. This may enable the tensioning system components to
have a lower profile on the medial side than on the lateral side of
footwear 105, which may minimize possible interference with
footwear 105 on the other foot of the wearer.
[0062] In some embodiments, motorized tightening device 150 may be
configured to automatically regulate tension in tensile member 120
for purposes of tightening, loosening, and regulating the fit of
upper 110. Embodiments can incorporate a variety of sensors for
providing information to a control unit of a motorized tensioning
system. In some embodiments an H-bridge mechanism may be used to
measure current. The measured current may be provided as an input
to the control unit. In some cases, a predetermined current may be
known to correspond to a certain level of tension in the tensile
member. By checking the measured current against the predetermined
current, a motorized tensioning system may adjust the tension of
the tensile member until the predetermined current is measured,
which indicates the desired tension has been achieved.
[0063] With current as a feedback, a variety of digital control
strategies can be used. For instance, proportional control only
could be used. Alternatively, PI control could be used or full PID.
In cases some cases, simple averaging could be used or other
filtering techniques including fuzzy logic and band-pass to reduce
noise.
[0064] Still other embodiments can include additional types of
sensors. In some cases, pressure sensors could be used under the
insoles of an article to indicate when the user is standing. A
motorized tensioning system can be programmed to automatically
loosen the tension of the lace when the user moves from the
standing position to a sitting position. Such a configuration may
be useful for older adults that may require low tension when
sitting to promote blood circulation but high tension for safety
when standing.
[0065] Still other embodiments could include additional tension
sensing elements. In one embodiment, three point bend indicators
could be used in the lace to more accurately monitor the state of
the tensioning system, including the lace. In other embodiments,
various devices to measure deflection such as capacitive or
inductive devices could be used. In some other embodiments, strain
gauges could be used to measure tension induced strain in one or
more components of a tensioning system.
[0066] In some embodiments, sensors such as gyroscopes and
accelerometers could be incorporated into a tensioning system. In
some embodiments, an accelerometer and/or gyroscope could be used
to detect sudden moment and/or position information that may be
used as feedback for adjusting lace tension. These sensors could
also be implemented to control periods of sleep/awake to extend
battery life. In some cases, for example, information from these
sensors could be used to reduce tension in a system when the user
is inactive, and increase tension during periods of greater
activity.
[0067] Some embodiments may use memory (for example onboard memory
associated with a control unit) to store sensed data over time.
This data may be stored for later upload and analysis. For example,
one embodiment of an article of footwear may sense and store
tension information over time that can be later evaluated to look
at trends in tightening.
[0068] It is also contemplated that some embodiments could
incorporate pressure sensors to detect high pressure regions that
may develop during tightening. In some cases, the tension of the
lace could be automatically reduced to avoid such high pressure
regions. Additionally, in some cases, a system could prompt a user
to alter them to these high pressure regions and suggest ways of
avoiding them (by altering use or fit of the article).
[0069] It is contemplated that in some embodiments a user could be
provided with feedback through motor pulsing, which generates
haptic feedback for the user in the form of vibrations/sounds. Such
provisions could facilitate operation of a tensioning system
directly, or provide haptic feedback for other systems in
communication with a motorized tightening device.
[0070] Various methods of automatically operating a motorized
tightening device in response to various inputs can be used. For
example, after initially tightening a shoe, it is common for the
lace tension to quickly decline in the first few minutes of use.
Some embodiments of a tensioning system may include provisions for
readjusting lace tension to the initial tension set by the user. In
some embodiments, a control unit may be configured to monitor
tension in those first minutes to then readjust tension to match
original tension.
[0071] Components of motorized tensioning system 145 may have any
suitable configurations. For example, components of motorized
tensioning system 145 may have any suitable configurations
disclosed in Beers, U.S. Patent Application Publication No.
2014/0082963, published on Mar. 27, 2014, and entitled "Footwear
Having Removable Motorized Adjustment System," the entire
disclosure of which is incorporated herein by reference.
[0072] Mounting the tensioning system components on the outer
surface of the upper prevents these components from taking up space
in other parts of the shoe, for example, between layers of the
upper, or within the sole structure. In some embodiments, removable
covers may be attached, covering the individual components of the
tensioning system. These covers may enable the inclusion of these
components on the footwear to be celebrated, while concealing their
outward appearance. For example, the covers may be formed to have
any desired appearance and, accordingly, may be used to conceal the
appearance of the tightening device, control unit, and/or power
source, for instance. In addition, such covers may protect these
components from damage.
[0073] As shown in FIG. 1, footwear 105 may include a tightening
device cover 185 configured to be removably attached to footwear
105 over tightening device 150. In addition, footwear 105 may
include a control unit cover 195 configured to be removably
attached to footwear 105 over control unit 155, and a power source
cover 190 configured to be removably attached to footwear 105.
Tightening device cover 185, power source cover 190, and/or control
unit cover 195 may be removably attached by any suitable mechanism.
For example, as shown in FIG. 1, these covers may be removably
attached to the article of footwear with an interference fit
connection. Alternative removable connections may be used, such as
hook and loop fasteners, threaded fasteners, press-fit connections,
snap fit connections, or any other suitable removable
connection.
[0074] The tensioning system component covers may have any suitable
shape. For example, as shown in FIG. 1, tightening device cover
185, power source cover 190, and/or control unit cover 195 may have
faceted configurations. For purposes of this disclosure, the term
"faceted" shall refer to the inner and/or outer surface of a cover
being formed to have a plurality of planar surfaces ("facets")
arranged at various angles to one another like a gem. In contrast a
"smoothly contoured" surface will be understood to have no adjacent
planar surfaces, but instead smoothly curved surfaces.
[0075] Further, in some embodiments, these covers may have
polygonal outer edges. In some embodiments, one or more of these
covers may have regular polygonal shapes. In some embodiments, one
or more of these covers may have non-regular polygonal shapes. The
faceted configurations may include faceted inner surfaces, which
define concave contours configured to receive the tensioning system
components.
[0076] In some embodiments, one or more of the covers may be
transparent or semi-transparent. For example, in some embodiments,
one or more of the covers may be formed of a colored, translucent
material. Colored, translucent covers having faceted configurations
may have a gem-like appearance. Accordingly, utilizing such covers
may provide a more aesthetically appealing configuration than a
battery pack or circuit board, for example. In addition, such
covers may also provide protection to the tensioning system
components. The faceted configurations may provide the covers with
increased strength over certain non-faceted configurations.
[0077] FIG. 2 is a schematic illustration of an exploded, side
perspective view of footwear 105. FIG. 2 shows concave inner
surface 200 of power source cover 190. As shown in FIG. 2, power
source cover may have a faceted configuration. For example, inner
surface 200 of power source cover 190 may include a first perimeter
facet 201, a second perimeter facet 202, a third perimeter facet
203, a fourth perimeter facet 204, and a fifth perimeter facet 205.
In addition, inner surface 200 may include a first inner facet 211,
a second inner facet 212, a third inner facet 213, a fourth inner
facet 214, and a fifth inner facet 215.
[0078] As shown in FIG. 2, power source cover 190 may have a
generally pentagonal shape. However, other shapes are possible. In
addition, in some embodiments, power source cover 190 may be
symmetrical. In other embodiments, power source cover 190 may be
asymmetrical. The faceted configuration may provide inner surface
200 with a contoured concave shape configured to receive power
source 160.
[0079] As shown in FIG. 2, power source cover 190 may be configured
to be removably attached to outer surface 111 of upper 110 of
footwear 105. In some embodiments, power source cover 190 may be
removably attached to outer surface 111 by an interference fit
connection or a friction fit connection. For example, in some
embodiments, upper 110 may include a first attachment post 220 and
a second attachment post 225. Power source cover 190 may include a
first post receiving cylinder 230 and a second post receiving
cylinder 235. First attachment post 220 may be received within
first post receiving cylinder 230 with an interference fit or a
friction fit. Similarly, second attachment post 225 may be received
within second post receiving cylinder 235 with an interference fit
or a friction fit. Other suitable attachment mechanisms may also be
used to removably attach power source cover 190 to footwear
105.
[0080] FIG. 3 is a perspective, assembled view of footwear 105 and
power source cover 190 shown in FIG. 2. As shown in FIG. 3, power
source cover 190 may have an outer surface 240, which may also be
faceted in some embodiments. For example, as shown in FIG. 3, outer
surface 240 may include a first perimeter facet 241, a second
perimeter facet 242, a third perimeter facet 243, a fourth
perimeter facet 244, and a fifth perimeter facet 245. In addition,
outer surface 240 may include a first inner facet 251, a second
inner facet 252, a third inner facet 253, a fourth inner facet 254,
and a fifth inner facet 255. In some embodiments, the facets on the
inner surface and outer surface of tensioning system component
covers may correspond to one another.
[0081] FIG. 4 is a schematic illustration of an exploded, rear view
of footwear 105 and tightening device cover 185. As shown in FIG.
4, first tensile member 170 and second tensile member 175 may enter
tightening device 150 and may extend under at least one layer of
upper 110.
[0082] Tightening device cover 185 may include an inner surface
400, which may have a first perimeter facet 401, a second perimeter
facet 402, a third perimeter facet 403, a fourth perimeter facet
404, a fifth perimeter facet 405, and a sixth perimeter facet 406.
In addition, inner surface 400 may include a first inner facet 411,
a second inner facet 412, a third inner facet 413, a fourth inner
facet 414, a fifth inner facet 415, and a sixth inner facet
416.
[0083] As shown in FIG. 4, tightening device cover 185 may be
configured to be removably attached to outer surface 111 of upper
110 of footwear 105. In some embodiments, tightening device cover
185 may be removably attached to outer surface 111 by an
interference fit connection or a friction fit connection. For
example, in some embodiments, upper 110 may include a first
attachment post 420 and a second attachment post 425. Tightening
device cover 185 may include a first post receiving cylinder 430
and a second post receiving cylinder 435. First attachment post 420
may be received within first post receiving cylinder 430 with an
interference fit or a friction fit. Similarly, second attachment
post 425 may be received within second post receiving cylinder 435
with an interference fit or a friction fit. Other suitable
attachment mechanisms may also be used to removably attach
tightening device cover 185 to footwear 105.
[0084] FIG. 4 also includes a partial cross-sectional view of the
rearmost heal portion of footwear 105, tightening device 150, and
tightening device cover 185. As shown in FIG. 4, first post
receiving cylinder 430 may include a first channel 431 configured
to receive first attachment post 420. As further shown in FIG. 4,
first channel 431 may include a first enlarged portion 432
configured to receive a bulbous portion at the end of first
attachment post 432, thus forming an interference fit. Second post
receiving cylinder 435 may include a second channel 436 configured
to receive second attachment post 425. Further, second post
receiving cylinder 435 may include a second enlarged portion 437
configured to receive a bulbous portion at the end of second
attachment post 425 to provide an interference fit.
[0085] The cross-sectional view in FIG. 4 also shows that the
faceted inner surface 400 of tightening device cover 185 may define
concave contours configured to receive tightening device 150. For
example, as shown in FIG. 4, tightening device cover 185 may define
a cavity 440 configured to receive tightening device 150 when
tightening device cover 185 is attached to outer surface 111 of
upper 110.
[0086] FIG. 5 is an assembled view of footwear 105, showing
tightening device cover 185 attached to upper 110. As shown in FIG.
5, tightening device cover 185 may have a faceted outer surface
500. For example, outer surface 500 may include a first perimeter
facet 501, a second perimeter facet 502, a third perimeter facet
503, a fourth perimeter facet 504, a fifth perimeter facet 505, and
a sixth perimeter facet 506. In addition, outer surface 500 may
include a first inner facet 511, a second inner facet 512, a third
inner facet 513, a fourth inner facet 514, a fifth inner facet 515,
and a sixth inner facet 516. Although FIG. 5 illustrates tightening
device cover 185 as having a substantially regular polygonal shape,
other, non-regular shapes may also be used.
[0087] FIG. 6 is a schematic illustration of a side perspective
view of footwear 105 and control unit cover 195. As shown in FIG.
6, control unit cover 195 may be removably attachable to footwear
105. For example, control unit 155 may include an attachment post
520 and control unit cover 195 may include a post receiving
cylinder 525 configured to receive attachment post 520. This may
provide an interference fit or friction fit connection that is the
same or similar to that described above with respect to FIG. 4.
[0088] The faceted configuration of control unit cover 195 may
define a concave contour configured to receive control unit 155.
For example, as shown in FIG. 6, control unit cover 195 may include
a faceted inner surface 600. In some embodiments, inner surface 600
may include a first perimeter facet 601, a second perimeter facet
602, a third perimeter facet 603, a fourth perimeter facet 604, and
a fifth perimeter facet 605. In addition, inner surface 600 may
also include a first inner facet 611, a second inner facet 612, a
third inner facet 613, a fourth inner facet 614, and a fifth inner
facet 615.
[0089] FIG. 7 is an assembled view of footwear 105 and control unit
cover 195. FIG. 7 also shows tightening device cover 185 attached
to upper 110. As shown in FIG. 7 an outer surface 700 of control
unit cover 195 may be faceted. For example, outer surface 700 may
include a first perimeter facet 701, a second perimeter facet 702,
a third perimeter facet 703, a fourth perimeter facet 704, and a
fifth perimeter facet 705. In addition, outer surface 700 may
include a first inner facet 711, a second inner facet 712, a third
inner facet 713, a fourth inner facet 714, and a fifth inner facet
715.
[0090] In some embodiments, edges of tensioning system component
covers that contact the outer surface of the upper may have
contours configured to mate with the contours of the upper. For
example, in some embodiments, the edges of the covers may have
curvatures that correspond with the curvature of a heel region of
the upper of the article of footwear. By having these mating
curvatures, a close fit may be provided between the covers and the
outer surface of the upper. This may substantially prevent debris
from contacting the tensioning system components. This close fit
may also substantially prevent apparel, such as pant leg cuffs from
becoming pinched between the covers and the upper.
[0091] FIG. 8 is a top view of footwear 105 with all three of the
tensioning system component covers attached. As shown in FIG. 8,
tightening device cover 185 may have a first contoured edge 186
that is curved to correspond with the curvature at the rearmost
portion of the heel region of upper 110. Similarly, power source
cover 190 may include a second contoured edge 191. As shown in FIG.
8, second contoured edge 191 may be curved to correspond with the
curvature on the right side of the upper. Also, control unit cover
195 may include a third contoured edge 196. As shown in FIG. 8,
third contoured edge 196 may be curved to correspond with the
curvature on the left side of the upper.
[0092] In some other embodiments, buttons for tightening, loosening
and/or performing other functions can be located directly on the
footwear. As an example, some embodiments could incorporate one or
more buttons located on or adjacent to the housing of a motorized
tightening device. In still other embodiments, a motorized
tightening device maybe controlled using voice commands. These
commands could be transmitted through a remote device, or to a
device capable of receiving voice commands that is integrated into
the article and in communication with the motorized tightening
device.
[0093] In some embodiments, the motorized tightening device may be
configured to be controlled by a remote device. Accordingly, the
footwear adjustment system may include a remote device configured
to control the motorized tightening device. For example, in some
embodiments, the remote device may include a bracelet, wristband,
or armband that is worn by a user and specifically designed for
communicating with the tensioning system.
[0094] In some embodiments, other types of mobile devices, such as
mobile phones, may be configured to control the tensioning system.
In some embodiments, the remote device may include a mobile phone,
such as the iPhone made by Apple, Inc. In other embodiments, any
other kinds of mobile phones could also be used including
smartphones. In other embodiments, any portable electronic devices
could be used including, but not limited to: personal digital
assistants, digital music players, tablet computers, laptop
computers, ultrabook computers as well as any other kinds of
portable electronic devices. In still other embodiments, any other
kinds of remote devices could be used including remote devices
specifically designed for controlling the tensioning system. The
type of remote device could be selected according to software and
hardware requirements, ease of mobility, manufacturing expenses, as
well as possibly other factors.
[0095] FIG. 9 is a schematic illustration of footwear 105 with a
motorized tensioning system and a remote device 900 for controlling
the tensioning system. In particular, FIG. 9 shows remote device
900 as a mobile phone. It will be understood that remote device 900
may be any suitable device for communicating with control unit
155.
[0096] In some embodiments, the control unit may be configured to
communicate with the remote device. In some cases, the control unit
may be configured to receive operating instructions from the remote
device. Accordingly, the remote device may be configured to
communicate instructions to the control unit. Therefore, control
unit 155 may be configured to receive instructions from remote
device 900 to apply increased tension to the tensile member by
winding the spool. In some cases, remote device 900 may be capable
of receiving information from control unit 155. For example, remote
device 900 could receive information related to the current tension
in the tensile member and/or other sensed information. Accordingly,
in some embodiments, remote device 900 may function as a remote
control that may be used by the wearer to operate the tensioning
system.
[0097] Examples of different communication methods between remote
device 900 and the tensioning system may include wireless networks
such as personal area networks (e.g., BLUETOOTH.RTM.) and local
area networks (e.g., Wi-Fi), as well as any kinds of RF based
methods known in the art. In some embodiments, infrared light may
be used for wireless communication. Although the illustrated
embodiments detail a remote device that communicates wirelessly
with the motorized tensioning system, in other embodiments the
remote device and tensioning system may be physically connected and
communicate through one or more wires.
[0098] The disclosed lace adjustment system may be usable to
perform a variety of functions related to the tensioning of the
tensile member. The tensioning system components and the remote
device may be configured to perform any of the operative functions
described in Beers, U.S. Patent Application Publication No.
2014/0082963, published on Mar. 27, 2014, and entitled "Footwear
Having Removable Motorized Adjustment System," the entire
disclosure of which is incorporated herein by reference.
[0099] FIG. 10 is a schematic illustration of an exploded, rear
perspective view of footwear 105 with an alternative set of covers
for the components of the tensioning system. As shown in FIG. 10, a
second tightening device cover 1085 may be removably attached to
upper 110 of footwear 105 over tightening device 150. Further, a
second power source cover 1090 may be removably attached to upper
110 over power source 160. In addition, a second control unit cover
1095 may be configured to be removably attached to footwear 105
over control unit 155.
[0100] As shown in FIG. 1, these second covers may be
interchangeable with the faceted covers described above. As opposed
to the faceted configurations described above, second tightening
device cover 1085, second power source cover 1090, and second
control unit cover 1095 may have substantially smoothly contoured
outer surfaces. The substantially smoothly contoured outer surfaces
may prevent edges of the covers from catching on the wearer's other
shoe or on obstacles. For example, during athletic activities,
smoothly contoured covers may be beneficial in preventing the
wearer from catching a cover on the footwear of an opponent. When
contact is made with a smoothly contoured cover, the cover may
merely glance off, with little or no impedance to the motion of the
wearer's foot.
[0101] FIG. 11 is a schematic illustration of a rear view and
partial cross-sectional view of footwear 105 with the second set of
covers attached. As shown in FIG. 11, second tightening device
cover 1085, second power source cover 1090, and second control unit
cover 1095 may have smooth contours. As shown in the partial
cross-sectional view in FIG. 11, second tightening device cover
1085 may have an outer surface 1110 having a smoothly contoured
profile, that is, without facets. As further shown in FIG. 11,
second tightening device cover 1085 may have an inner surface 1105
that is concavely contoured to define a cavity 1440 configured to
receive tightening device 150.
[0102] As also shown in FIG. 11, second tightening device cover
1085 may be configured to attach to outer surface 111 of upper 110
of footwear 105 with the same connection mechanism as the faceted
tightening device cover discussed above. For example, in some
embodiments, second tightening device cover 1085 may include a
first post receiving cylinder 1430 configured to receive first
attachment post 420 and a second post receiving cylinder 1435
configured to receive second attachment post 425 of upper 110 in an
interference fit or friction fit connection.
[0103] FIG. 12 is a schematic illustration of motorized footwear
lacing system including 1200 including interchangeable tensioning
system component covers. As shown in FIG. 12, system 1200 may
include footwear 105, as well as tightening device cover 185, power
source cover 190, and control unit cover 195. System 1200 may also
include a second article of footwear 106 matching with footwear 105
(for example, a right and left pair). Accordingly, system 1200 may
include a second faceted tightening device cover 1285 configured to
be attached to footwear 106 over a tightening device, a second
faceted power source cover 1290 configured to be attached to
footwear 106 over a power source, and a second faceted control unit
cover 1295 configured to be attached to footwear 106 over a control
unit. Thus, system 1200 may include a first set of component covers
1210, which may include tightening device cover 185, power source
cover 190, and control unit cover 195, second faceted tightening
device cover 1285, second faceted power source cover 1290, and
second faceted control unit cover 1295.
[0104] In some cases the arrangement of the tensioning system
components may be medial/lateral specific. Accordingly, in some
cases, the second faceted covers may be mirror images of their
counterpart for the mating shoe. For example, control unit cover
195 and second faceted control unit cover 1295 are illustrated as
having mirror images, in order to fit over the control units of
footwear 105 and footwear 106, which are disposed on the medial
side of each shoe. In other cases, the covers may have horizontal
and/or vertical symmetry, as shown in FIG. 12.
[0105] As shown in FIG. 12, system 1200 may also include a second
set of tension system component covers 1215. As shown in FIG. 12,
second set of covers 1215 may have different external shapes than
first set of covers 1210. For example, second set of covers 1215
may include second tightening device cover 1085, second power
source cover 1090, and second control unit cover 1095. In addition,
second set of covers 1215 may further include covers for the mating
footwear 106, including a second contoured second contoured
tightening device cover 1385, a second contoured power source cover
1390, and a second contoured control unit cover 1395.
[0106] First set of covers 1210 may be interchangeable with second
set of covers 1215. The sets of covers may be attached to the
footwear as complete sets or as individual covers by mixing and
matching faceted covers with smoothly contoured covers.
[0107] As shown in FIG. 12, system 1100 may be a kit of parts.
Accordingly, the kit of parts may include a container 1206
configured to contain footwear 105 and other components of system
1200. For example, in some cases, container 1206 may be a shoebox.
The various components of system 1200 may be included in container
1206. For example, footwear 105 may be included in container 1206
as indicated by a first arrow 1220. Mating footwear 106 may also be
included, as indicated by a second arrow 1225. First set of covers
1210 may be included, as indicated by a third arrow 1230. Further,
second set of covers 1215 may be included, as indicated by a fourth
arrow 1235.
[0108] FIG. 12 also illustrates a remote device 1205, which may
also be included in container 1206. Remote device 1205 is
illustrated as a bracelet or watch. The features of remote device
1205 may be the same or similar to the remote devices discussed
above.
[0109] In some embodiments, a method of changing a lacing system of
an article of footwear may include removing a first tightening
device cover from the article of footwear and removably attaching a
second, interchangeable tightening device cover to the article of
footwear over the tightening device. The covers for the power
source and control unit may be similarly interchanged.
[0110] While various embodiments of the invention have been
described, the description is intended to be exemplary, rather than
limiting and it will be apparent to those of ordinary skill in the
art that many more embodiments and implementations are possible
that are within the scope of the invention. Although many possible
combinations of features are shown in the accompanying figures and
discussed in this detailed description, many other combinations of
the disclosed features are possible. Therefore, it will be
understood that any of the features shown and/or discussed in the
present disclosure may be implemented together in any suitable
combination. Accordingly, the invention is not to be restricted
except in light of the attached claims and their equivalents. Also,
various modifications and changes may be made within the scope of
the attached claims.
