The following specification describes various aspects of a motorized lacing system, motorized and non-motorized lacing engines, footwear components related to the lacing engines, automated lacing footwear platforms, and related assembly processes. The following specification also describes various aspects of systems and methods for a modular spool assembly for a lacing engine.
Devices for automatically tightening an article of footwear have been previously proposed. Liu, in U.S. Pat. No. 6,691,433, titled “Automatic tightening shoe”, provides a first fastener mounted on a shoe's upper portion, and a second fastener connected to a closure member and capable of removable engagement with the first fastener to retain the closure member at a tightened state. Liu teaches a drive unit mounted in the heel portion of the sole. The drive unit includes a housing, a spool rotatably mounted in the housing, a pair of pull strings and a motor unit. Each string has a first end connected to the spool and a second end corresponding to a string hole in the second fastener. The motor unit is coupled to the spool. Liu teaches that the motor unit is operable to drive rotation of the spool in the housing to wind the pull strings on the spool for pulling the second fastener towards the first fastener. Liu also teaches a guide tube unit that the pull strings can extend through.
In the drawings, which are not necessarily drawn to scale, like numerals may describe similar components in different views. Like numerals having different letter suffixes may represent different instances of similar components. The drawings illustrate generally, by way of example, but not by way of limitation, various embodiments discussed in the present document.
The headings provided herein are merely for convenience and do not necessarily affect the scope or meaning of the terms used.
The concept of self-tightening shoe laces was first widely popularized by the fictitious power-laced Nike® sneakers worn by Marty McFly in the movie Back to the Future II, which was released back in 1989. While Nike® has since released at least one version of power-laced sneakers similar in appearance to the movie prop version from Back to the Future II, the internal mechanical systems and surrounding footwear platform employed do not necessarily lend themselves to mass production or daily use. Additionally, previous designs for motorized lacing systems comparatively suffered from problems such as high cost of manufacture, complexity, assembly challenges, lack of serviceability, and weak or fragile mechanical mechanisms, to highlight just a few of the many issues. The present inventors have developed a modular footwear platform to accommodate motorized and non-motorized lacing engines that solves some or all of the problems discussed above, among others. The components discussed below provide various benefits including, but not limited to: serviceable components, interchangeable automated lacing engines, robust mechanical design, reliable operation, streamlined assembly processes, and retail-level customization. Various other benefits of the components described below will be evident to persons of skill in the relevant arts.
The motorized lacing engine discussed below was developed from the ground up to provide a robust, serviceable, and inter-changeable component of an automated lacing footwear platform. The lacing engine includes unique design elements that enable retail-level final assembly into a modular footwear platform. The lacing engine design allows for the majority of the footwear assembly process to leverage known assembly technologies, with unique adaptions to standard assembly processes still being able to leverage current assembly resources.
In an example, a footwear lacing apparatus can comprise a housing structure, a spool and a drive mechanism. The housing structure can comprise a first inlet, a second inlet, and a lacing channel extending between the first and second inlets. The lacing channel can comprise a spool receptacle located between the first and second inlets, a first relief area located between the spool receptacle and the first inlet, and a second relief area located between the spool receptacle and the second inlet. The first and second relief areas can be linearly tapered between the spool receptacle and the first and second inlets, respectively. The spool can be disposed in the spool receptacle of the lacing channel. The drive mechanism can be coupled with the spool and adapted to rotate the spool to wind or unwind a lace cable extending through the lacing channel and through the spool.
The automated footwear platform discussed herein can include a housing structure for a footwear lacing apparatus. The housing structure can comprise a body, an internal compartment and a lacing channel. The body can comprise a top surface, a bottom surface, a first sidewall connecting the top surface and the bottom surface, and a second sidewall connecting the top surface and the bottom surface. The internal compartment can be between the top and bottom surfaces and the first and second sidewalls. The lacing channel can extending from the first sidewall to the second sidewall. The lacing channel can comprise a first inlet in the first sidewall, a second inlet in the second sidewall, a spool receptacle located between the first and second inlets, a first relief area located between the spool receptacle and the first inlet, and a second relief area located between the spool receptacle and the second inlet. The first and second relief areas can be linearly tapered between the spool receptacle and the first and second inlets, respectively.
A method of unwinding a spool in a footwear lacing apparatus can comprise rotating a spool with a drive mechanism to reduce tension in a lace cable wrapped around the spool, pushing lace cable from the spool into a lacing channel within a housing of the footwear lacing apparatus, collecting lace cable within relief areas of the lacing channel, and permitting lace cable to loosely exit the lacing channel from the relief areas to unwind the lace cable from the spool.
This initial overview is intended to introduce the subject matter of the present patent application. It is not intended to provide an exclusive or exhaustive explanation of the various inventions disclosed in the following more detailed description.
Automated Footwear Platform
The following discusses various components of the automated footwear platform including a motorized lacing engine, a mid-sole plate, and various other components of the platform. While much of this disclosure focuses on a motorized lacing engine, many of the mechanical aspects of the discussed designs are applicable to a human-powered lacing engine or other motorized lacing engines with additional or fewer capabilities. Accordingly, the term “automated” as used in “automated footwear platform” is not intended to only cover a system that operates without user input. Rather, the term “automated footwear platform” includes various electrically powered and human-power, automatically activated and human activated mechanisms for tightening a lacing or retention system of the footwear.
In an example, the footwear article or the motorized lacing system 1 includes or is configured to interface with one or more sensors that can monitor or determine a foot presence characteristic. Based on information from one or more foot presence sensors, the footwear including the motorized lacing system 1 can be configured to perform various functions. For example, a foot presence sensor can be configured to provide binary information about whether a foot is present or not present in the footwear. If a binary signal from the foot presence sensor indicates that a foot is present, then the motorized lacing system 1 can be activated, such as to automatically tighten or relax (i.e., loosen) a footwear lacing cable. In an example, the footwear article includes a processor circuit that can receive or interpret signals from a foot presence sensor. The processor circuit can optionally be embedded in or with the lacing engine 10, such as in a sole of the footwear article.
In an example, a foot presence sensor can be configured to provide information about a location of a foot as it enters footwear. The motorized lacing system 1 can generally be activated, such as to tighten a lacing cable, only when a foot is appropriately positioned or seated in the footwear, such as against all or a portion of the footwear article's sole. A foot presence sensor that senses information about a foot travel or location can provide information about whether a foot is fully or partially seated, such as relative to a sole or relative to some other feature of the footwear article. Automated lacing procedures can be interrupted or delayed until information from the sensor indicates that a foot is in a proper position.
In an example, a foot presence sensor can be configured to provide information about a relative location of a foot inside of footwear. For example, the foot presence sensor can be configured to sense whether the footwear is a good “fit” for a given foot, such as by determining a relative position of one or more of a foot's arch, heel, toe, or other component, such as relative to the corresponding portions of the footwear that are configured to receive such foot components. In an example, the foot presence sensor can be configured to sense whether a position of a foot or a foot component has changed relative to some reference, such as due to loosening of a lacing cable over time, or due to natural expansion and contraction of a foot itself.
In an example, a foot presence sensor can include an electrical, magnetic, thermal, capacitive, pressure, optical, or other sensor device that can be configured to sense or receive information about a presence of a body. For example, an electrical sensor can include an impedance sensor that is configured to measure an impedance characteristic between at least two electrodes. When a body such as a foot is located proximal or adjacent to the electrodes, the electrical sensor can provide a sensor signal having a first value, and when a body is located remotely from the electrodes, the electrical sensor can provide a sensor signal having a different second value. For example, a first impedance value can be associated with an empty footwear condition, and a lesser second impedance value can be associated with an occupied footwear condition.
An electrical sensor can include an AC signal generator circuit and an antenna that is configured to emit or receive radio frequency information. Based on proximity of a body relative to the antenna, one or more electrical signal characteristics, such as impedance, frequency, or signal amplitude, can be received and analyzed to determine whether a body is present. In an example, a received signal strength indicator (RSSI) provides information about a power level in a received radio signal. Changes in the RSSI, such as relative to some baseline or reference value, can be used to identify a presence or absence of a body. In an example, WiFi frequencies can be used, for example in one or more of 2.4 GHz, 3.6 GHz, 4.9 GHz, 5 GHz, and 5.9 GHz bands. In an example, frequencies in the kilohertz range can be used, for example, around 400 kHz. In an example, power signal changes can be detected in milliwatt or microwatt ranges.
A foot presence sensor can include a magnetic sensor. A first magnetic sensor can include a magnet and a magnetometer. In an example, a magnetometer can be positioned in or near the lacing engine 10. A magnet can be located remotely from the lacing engine 10, such as in a secondary sole, or insole, that is configured to be worn above the outsole 60. In an example, the magnet is embedded in a foam or other compressible material of the secondary sole. As a user depresses the secondary sole such as when standing or walking, corresponding changes in the location of the magnet relative to the magnetometer can be sensed and reported via a sensor signal.
A second magnetic sensor can include a magnetic field sensor that is configured to sense changes or interruptions (e.g., via the Hall effect) in a magnetic field. When a body is proximal to the second magnetic sensor, the sensor can generate a signal that indicates a change to an ambient magnetic field. For example, the second magnetic sensor can include a Hall effect sensor that varies a voltage output signal in response to variations in a detected magnetic field. Voltage changes at the output signal can be due to production of a voltage difference across an electric signal conductor, such as transverse to an electric current in the conductor and a magnetic field perpendicular to the current.
In an example, the second magnetic sensor is configured to receive an electromagnetic field signal from a body. For example, Varshaysky et al., in U.S. Pat. No. 8,752,200, titled “Devices, systems and methods for security using magnetic field based identification”, teaches using a body's unique electromagnetic signature for authentication. In an example, a magnetic sensor in a footwear article can be used to authenticate or verify that a present user is a shoe's owner via a detected electromagnetic signature, and that the article should lace automatically, such as according to one or more specified lacing preferences (e.g., tightness profile) of the owner.
In an example, a foot presence sensor includes a thermal sensor that is configured to sense a change in temperature in or near a portion of the footwear. When a wearer's foot enters a footwear article, the article's internal temperature changes when the wearer's own body temperature differs from an ambient temperature of the footwear article. Thus the thermal sensor can provide an indication that a foot is likely to present or not based on a temperature change.
In an example, a foot presence sensor includes a capacitive sensor that is configured to sense a change in capacitance. The capacitive sensor can include a single plate or electrode, or the capacitive sensor can include a multiple-plate or multiple-electrode configuration. Capacitive-type foot presence sensors are described at length below.
In an example, a foot presence sensor includes an optical sensor. The optical sensor can be configured to determine whether a line-of-sight is interrupted, such as between opposite sides of a footwear cavity. In an example, the optical sensor includes a light sensor that can be covered by a foot when the foot is inserted into the footwear. When the sensor indicates a change in a sensed lightness condition, an indication of a foot presence or position can be provided.
In an example, the housing structure 100 provides an air tight or hermetic seal around the components that are enclosed by the housing structure 100. In an example, the housing structure 100 encloses a separate, hermetically sealed cavity in which a pressure sensor can be disposed. See
Examples of the lacing engine 10 are described in detail in reference to
In an example, the lacing engine 10 is held together by one or more screws, such as the case screw 108. The case screw 108 is positioned near the primary drive mechanisms to enhance structural integrity of the lacing engine 10. The case screw 108 also functions to assist the assembly process, such as holding the case together for ultra-sonic welding of exterior seams.
In this example, the lacing engine 10 includes a lace channel 110 to receive a lace or lace cable once assembled into the automated footwear platform. The lace channel 110 can include a lace channel wall 112. The lace channel wall 112 can include chamfered edges to provide a smooth guiding surface for a lace cable to run in during operation. Part of the smooth guiding surface of the lace channel 110 can include a channel transition 114, which is a widened portion of the lace channel 110 leading into the spool recess 115. The spool recess 115 transitions from the channel transition 114 into generally circular sections that conform closely to the profile of the spool 130. The spool recess 115 assists in retaining the spooled lace cable, as well as in retaining position of the spool 130. However, other aspects of the design provide primary retention of the spool 130. In this example, the spool 130 is shaped similarly to half of a yo-yo with a lace grove 132 running through a flat top surface and a spool shaft 133 (not shown in
The lateral side of the lacing engine 10 includes button openings 120 that enable buttons 121 for activation of the mechanism to extend through the housing structure 100. The buttons 121 provide an external interface for activation of switches 122, illustrated in additional figures discussed below. In some examples, the housing structure 100 includes button membrane seal 124 to provide protection from dirt and water. In this example, the button membrane seal 124 is up to a few mils (thousandth of an inch) thick clear plastic (or similar material) adhered from a superior surface of the housing structure 100 over a corner and down a lateral side. In another example, the button membrane seal 124 is a 2 mil thick vinyl adhesive backed membrane covering the buttons 121 and button openings 120.
In this example, the bottom section 104 includes features such as wireless charger access 105, joint 106, and grease isolation wall 109. Also illustrated, but not specifically identified, is the case screw base for receiving case screw 108 as well as various features within the grease isolation wall 109 for holding portions of a drive mechanism. The grease isolation wall 109 is designed to retain grease or similar compounds surrounding the drive mechanism away from the electrical components of the lacing engine 10 including the gear motor and enclosed gear box.
In this example, major drive components of the lacing engine 10 include worm drive 140, worm gear 150, gear motor 145 and gear box 144. The worm gear 150 is designed to inhibit back driving of worm drive 140 and gear motor 145, which means the major input forces coming in from the lacing cable via the spool 130 are resolved on the comparatively large worm gear and worm drive teeth. This arrangement protects the gear box 144 from needing to include gears of sufficient strength to withstand both the dynamic loading from active use of the footwear platform or tightening loading from tightening the lacing system. The worm drive 140 includes additional features to assist in protecting the more fragile portions of the drive system, such as the worm drive key 142. In this example, the worm drive key 142 is a radial slot in the motor end of the worm drive 140 that interfaces with a pin through the drive shaft coming out of the gear box 144. This arrangement prevents the worm drive 140 from imparting any axial forces on the gear box 144 or gear motor 145 by allowing the worm drive 140 to move freely in an axial direction (away from the gear box 144) transferring those axial loads onto bushing 141 and the housing structure 100.
As illustrated by the cross-section of lacing engine 10, the spool 130 includes a spool shaft 133 that couples with worm gear 150 after running through an O-ring 138. In this example, the spool shaft 133 is coupled to the worm gear via keyed connection pin 134. In some examples, the keyed connection pin 134 only extends from the spool shaft 133 in one axial direction, and is contacted by a key on the worm gear in such a way as to allow for an almost complete revolution of the worm gear 150 before the keyed connection pin 134 is contacted when the direction of worm gear 150 is reversed. A clutch system could also be implemented to couple the spool 130 to the worm gear 150. In such an example, the clutch mechanism could be deactivated to allow the spool 130 to run free upon de-lacing (loosening). In the example of the keyed connection pin 134 only extending is one axial direction from the spool shaft 133, the spool is allowed to move freely upon initial activation of a de-lacing process, while the worm gear 150 is driven backward. Allowing the spool 130 to move freely during the initial portion of a de-lacing process assists in preventing tangles in the lace 131 as it provides time for the user to begin loosening the footwear, which in turn will tension the lace 131 in the loosening direction prior to being driven by the worm gear 150.
In this example, the arms of the actuator 30, posterior arm 330 and anterior arm 334, include flanges to prevent over activation of switches 122 providing a measure of safety against impacts against the side of the footwear platform. The large central arm 332 is also designed to carry impact loads against the side of the lacing engine 10, instead of allowing transmission of these loads against the buttons 121.
The medial lace guide 420 and lateral lace guide 421 assist in guiding lace cable into the lace engine pocket 410 and over lacing engine 10 (when present). The medial/lateral lace guides 420, 421 can include chamfered edges and inferiorly slated ramps to assist in guiding the lace cable into the desired position over the lacing engine 10. In this example, the medial/lateral lace guides 420, 421 include openings in the sides of the mid-sole plate 40 that are many times wider than the typical lacing cable diameter, in other examples the openings for the medial/lateral lace guides 420, 421 may only be a couple times wider than the lacing cable diameter.
In this example, the mid-sole plate 40 includes a sculpted or contoured anterior flange 440 that extends much further on the medial side of the mid-sole plate 40. The example anterior flange 440 is designed to provide additional support under the arch of the footwear platform. However, in other examples the anterior flange 440 may be less pronounced in on the medial side. In this example, the posterior flange 450 also includes a particular contour with extended portions on both the medial and lateral sides. The illustrated posterior flange 450 shape provides enhanced lateral stability for the lacing engine 10.
As illustrated in
Assembly Processes
In this example, the process 700 begins at 710 with obtaining an out-sole and mid-sole assembly, such as mid-sole 50 adhered to out-sole 60. At 720, the process 700 continues with insertion of a mid-sole plate, such as mid-sole plate 40, into a plate recess 510. In some examples, the mid-sole plate 40 includes a layer of adhesive on the inferior surface to adhere the mid-sole plate into the mid-sole. In other examples, adhesive is applied to the mid-sole prior to insertion of a mid-sole plate. In still other examples, the mid-sole is designed with an interference fit with the mid-sole plate, which does not require adhesive to secure the two components of the automated footwear platform.
At 730, the process 700 continues with a laced upper portion of the automated footwear platform being attached to the mid-sole. Attachment of the laced upper portion is done through any known footwear manufacturing process, with the addition of positioning a lower lace loop into the mid-sole plate for subsequent engagement with a lacing engine, such as lacing engine 10. For example, attaching a laced upper to mid-sole 50 with mid-sole plate 40 inserted, the lower lace loop is positioned to align with medial lace guide 420 and lateral lace guide 421, which position the lace loop properly to engage with lacing engine 10 when inserted later in the assembly process. Assembly of the upper portion is discussed in greater detail in reference to
At 740, the process 700 continues with insertion of an actuator, such as actuator 30, into the mid-sole plate. Optionally, insertion of the actuator can be done prior to attachment of the upper portion at operation 730. In an example, insertion of actuator 30 into the actuator cutout 480 of mid-sole plate 40 involves a snap fit between actuator 30 and actuator cutout 480. Optionally, process 700 continues at 745 with shipment of the subassembly of the automated footwear platform to a retail location or similar point of sale. The remaining operations within process 700 can be performed without special tools or materials, which allows for flexible customization of the product sold at the retail level without the need to manufacture and inventory every combination of automated footwear subassembly and lacing engine options.
At 750, the process 700 continues with selection of a lacing engine, which may be an optional operation in cases where only one lacing engine is available. In an example, lacing engine 10, a motorized lacing engine, is chosen for assembly into the subassembly from operations 710-740. However, as noted above, the automated footwear platform is designed to accommodate various types of lacing engines from fully automatic motorized lacing engines to human-power manually activated lacing engines. The subassembly built up in operations 710-740, with components such as out-sole 60, mid-sole 50, and mid-sole plate 40, provides a modular platform to accommodate a wide range of optional automation components.
At 760, the process 700 continues with insertion of the selected lacing engine into the mid-sole plate. For example, lacing engine 10 can be inserted into mid-sole plate 40, with the lacing engine 10 slipped underneath the lace loop running through the lacing engine cavity 410. With the lacing engine 10 in place and the lace cable engaged within the spool of the lacing engine, such as spool 130, a lid (or similar component) can be installed into the mid-sole plate to secure the lacing engine 10 and lace. An example of install of lid 20 into mid-sole plate 40 to secure lacing engine 10 is illustrated in
The process 800 begins at 810 by obtaining an upper and a lace cable to being assembly. Obtaining the upper can include placing the upper on a lacing fixture used through other operations of process 800. At 820, the process 800 continues by lacing a first half of the upper with the lace cable. Lacing operation can include routing the lace cable through a series of eyelets or similar features built into the upper. The lacing operation at 820 can also include securing one end of the lace cable to a portion of the upper. Securing the lace cable can include sewing, tying off, or otherwise terminating a first end of the lace cable to a fixed portion of the upper.
At 830, the process 800 continues with routing the free end of the lace cable under the upper and around the lacing fixture. In this example, the lacing fixture is used to create a proper lace loop under the upper for eventual engagement with a lacing engine after the upper is joined with a mid-sole/out-sole assembly (see discussion of
At 840, the process 800 continues with lacing the second half of the upper with the free end of the lace cable. Lacing the second half can include routing the lace cable through a second series of eyelets or similar features on the second half of the upper. At 850, the process 800 continues by tightening the lace cable through the various eyelets and around the lacing fixture to ensure that the lower lace loop is properly formed for proper engagement with a lacing engine. The lacing fixture assists in obtaining a proper lace loop length, and different lacing fixtures can be used for different size or styles of footwear. The lacing process is completed at 860 with the free end of the lace cable being secured to the second half of the upper. Completion of the upper can also include additional trimming or stitching operations. Finally, at 870, the process 800 completes with removal of the upper from the lacing fixture.
In an example, the processor circuit controls one or more aspects of the drive mechanism. For example, the processor circuit can be configured to receive information from the buttons and/or from the foot presence sensor and/or from the battery and/or from the drive mechanism and/or from the encoder, and can be further configured to issue commands to the drive mechanism, such as to tighten or loosen the footwear, or to obtain or record sensor information, among other functions.
At 1020, the example includes determining whether a foot is fully seated in the footwear. If the sensor signal indicates that the foot is fully seated, then the example can continue at 1030 with actuating a lace drive mechanism. For example, when a foot is fully seated, the lace drive mechanism can be engaged to tighten footwear laces via a spool mechanism, as described above. If the sensor signal indicates that the foot is not fully seated, then the example can continue at 1022 by delaying or idling for some specified interval (e.g., 1-2 seconds, or more). After the delay elapses, the example can return to operation 1010, and the processor circuit can re-sample information from the foot presence sensor to determine again whether the foot is fully seated.
After the lace drive mechanism is actuated at 1030, the processor circuit can be configured to monitor foot location information at operation 1040. For example, the processor circuit can be configured to periodically or intermittently monitor information from the foot presence sensor about an absolute or relative position of a foot in the footwear. In an example, monitoring foot location information at 1040 and the receiving foot presence information at 1010 can include receiving information from the same or different foot position sensor. At 1040, the example includes monitoring information from one or more buttons associated with the footwear, such as can indicate a user instruction to disengage (loosen) the laces, such as when a user wishes to remove the footwear. In an example, lace tension information can be additionally or alternatively monitored or used as feedback information for actuating a drive motor or tensioning laces. For example, lace tension information can be monitored by measuring a drive motor current. The tension can be characterized at the factory or preset by the user, and can be correlated to a monitored or measured drive motor current level.
At 1050, the example includes determining whether a foot location has changed in the footwear. If no change in foot location is detected by the processor circuit, for example by analyzing foot presence signals from one or more foot presence sensors, then the example can continue with a delay 1052. After a specified delay interval, the example can return to 1040 to re-sample information from the foot presence sensor(s) to again determine whether a foot position has changed. The delay 1052 can be in the range of several milliseconds to several seconds, and can optionally be specified by a user.
In an example, the delay 1052 can be determined automatically by the processor circuit, such as in response to determining a footwear use characteristic. For example, if the processor circuit determines that a wearer is engaged in strenuous activity (e.g., running, jumping, etc.), then the processor circuit can decrease the delay 1052. If the processor circuit determines that the wearer is engaged in non-strenuous activity (e.g., walking or sitting), then the processor circuit can increase the delay 1052, such as to increase battery longevity by deferring sensor sampling events. In an example, if a location change is detected at 1050, then the example can continue by returning to operation 1030, for example, to actuate the lace drive mechanism, such as to tighten or loosen the footwear's laces. In an example, the processor circuit includes or incorporates a hysteretic controller for the drive mechanism to help avoid unwanted lace spooling.
Motor Control Scheme
Anti-Tangle Box Lace Channel Shape
Modular spool 1130 can be positioned within spool recess 1115 of lacing channel 1110. Lacing channel 1110 is shaped to optimize or improve performance of modular spool 1130 in winding and unwinding lace 131 from housing structure 1105. In particular, as discussed below, lacing channel 1110 can include lace channel transitions 1114, and other shapes, geometries and surfaces, that can help prevent lace 131 from jamming within spool recess 1115, such as by bird's nesting. Lace channel transitions 1114 can provide lacing channel 1110 with adequate volume to store lace 131 without having to compress or entangle lace 131.
An example lacing engine 1101 can include upper component 1102 and lower component 1104 of housing structure 1105, case screws 1108, lacing channel 1110 (also referred to as lace guide relief 1110), lace channel walls 1112, lace channel transitions 1114, spool recess 1115, button openings 1120, buttons 1121, button membrane seal 1124, programming header 1128, modular spool 1130, and winding channel (lace grove) 1132.
Housing structure 1105 is configured to provide a compact lacing engine for insertion into a sole of an article of footwear, as described herein, for example. Case screws 1108 can be used to hold upper component 1102 and lower component 1104 in engagement. Together, upper component 1102 and lower component 1104 provide an interior space for placement of components of motorized lacing system 1101, such as components of modular spool 1130 and worm drive 1140 (
Lace 131 (
Housing structure 1105 can comprise upper component 1102 and lower component 1104. Upper component 1102 can include lacing channel 1110 and spool recess 1115. Modular spool 1130 can comprise upper plate 1131, winding channel 1132, spool shaft 1133 and lower plate 1134. Lower component 1104 can include gear receptacle 1182, shaft socket 1188 and wheel post 1190.
Worm drive 1140 can comprise bushing 1141, key 1142, drive shaft 1143, gear box 1144, gear motor 1145, motor encoder 1146 and motor circuit board 1147. Worm drive 1140, circuit board 1160, wireless charging coil 1166 and battery 1170 can operate in a similar manner as worm drive 140, circuit board 160, wireless charging coil 166 and battery 170 described herein and further description is not provided here for brevity.
Fasteners 1183 can be used to secure upper plate 1131 to lower plate 1134 to form an assembled modular spool 1130. Seal 1138 can be positioned between upper plate 1131 and lower plate 1134 when assembled. Modular spool 1130 can be positioned into spool recess 1115 so that spool shaft 1133 is inserted into shaft bearing 1174. Lower plate 1134 can be configured to thereby seat in counterbore 1178 while upper plate 1131 is positioned adjacent spool flanges 1172 extending from spool walls 1116. Spool shaft 1133 can extend through shaft bearing 1174 and pass through engage worm gear 1150 at socket 1152 to engage shaft socket 1188.
Worm gear 1150 can be positioned within gear receptacle 1182 of lower component 1104. The distal tip of spool shaft 1133 can be inserted into socket 1188. Bore 1195 in indexing wheel 1151 can be positioned around wheel post 1190 such that indexing wheel 1151 is rotatable partially within socket 1188. With worm gear 1150 resting in gear receptacle 1182 and indexing wheel 1151 positioned on wheel post 1190, teeth of indexing wheel 1151 can mate with a tooth, such as tooth 153 (
When modular spool is 1130 is seated in counterbore 1178 within lacing channel 1110, modular spool 1130 defines a lace volume and lacing channel 1110 defines a storage volume. For example, modular spool 1130 can include a lace volume that is defined by the space between upper plate 1131 and lower plate 1134 and that extends from a central axis of modular spool 1130 to, at its further extent, the outer diameter edge of upper plate 1131. For example, lacing channel 1110 can include a storage volume that is defined by the spaces between lace wall transitions 1114 and that extends between lace channel walls 1112 and the lace volume. In various embodiments, the storage volume is greater than the lace volume.

Lace channel walls 1112 can comprise planar segments that extend perpendicular to axis A defined by lacing channel 1110. In
Channel transitions 1114 can comprise planar walls that can extend straight between channel walls 1112 and spool walls 1116. In the illustrated embodiment, channel transitions 1114 are joined to channel walls 1112 at their distal ends to form an angle therebetween. In other embodiments, a small curved surface or a radius can be positioned between channel transitions 1114 and channel walls 1112. In the illustrated embodiment, channel transitions 1114 are joined to spool walls 1116 at their proximal ends to from an angle therebetween. In other embodiments, channel transitions 1114 can be tangent to the curve of spool walls 1116, as shown by line T. In such embodiments, inlets formed by channel walls 1112 can or cannot be used. This can help maximize the volume of the aforementioned storage volume. In the illustrated embodiment, channel transitions 1114 extend to an inside corner of spool flanges 1172.
Channel floors 1176 can comprise flat or planar surfaces that extend between channel walls 1112 and channel lips 1180.
