A portion of the smooth guide surface of the raceway groove 110 is , can include a groove transition 114, which leads to a spool recess 115. The spool recess 115 is the widened portion of the race groove 110 that extends from the groove transition portion 114. , transitioning into a generally circular section that closely matches the contours of the spool 130. The spool recess 115 helps keep the lace cable wound on the spool and also However, other aspects of the design include the position of the spool 130. In this example, the spool 130 is shaped like half of a yo-yo. The raceway groove 132 runs through the flat top surface and is attached to the spool shaft 133. (not shown in FIG. 2A) extends downward from the opposite side. This is explained in further detail below with reference to additional figures.

[0033] The side of the racing engine 10 includes a button opening 120. A button 121 for actuating the mechanism extends through the housing structure 100. The button 121 provides an external interface for actuation of the switch 122. , which are illustrated in the additional figures discussed below. In this example, the housing structure 100 includes a button membrane seal 124 to protect against dust and water. In this example, the button membrane seal 124 is a few mils thick at most (1 mil is 2 5.4 micrometers (thousandths of an inch) thick clear plastic (or , or similar material), and this transparent plastic is In another example, the button membrane seal 124 is attached to the bottom of the button, covering the corners. 50.8 micrometers (2 mils) covering the pin 121 and button opening 120 It is a film with a vinyl adhesive of thickness.

[0034] FIG. 2B is an illustration of a housing structure 100 including a top portion 102 and a bottom portion 104. In this example, the top 102 includes case threads 108, race grooves 110, and race groove transitions 111. 4, such as a spool recess 115, a button opening 120, and a button seal recess 126.

[0037] In this example, the main driving component of the racing engine 10 is a worm drive. part 140, worm gear 150, gear motor 145, and gear box 144. The worm gear 150 controls the reverse rotation of the worm drive 140 and the gear motor 145. Designed to prevent drive, this prevents the lacing cable from spooling 13 The main input force coming in through the worm gear and worm This means that the teeth are distributed over the drive shaft. Dynamic loads from active use of the platform or tightening of the lacing system It must contain gears strong enough to withstand both the clamping load from The worm drive 140 protects the gear box 144 from This helps protect the more fragile parts of the drive, such as the worm drive key 142. In this example, the worm drive key 142 is connected to the gear box 144. The worm drive 140 motor interfaces with the pin through a drive shaft emerging from the This arrangement allows the worm drive 140 to rotate axially. allowing them to move freely in the direction (away from the gearbox 144) By transmitting the axial load to the bushing 141 and the housing structure 100, Therefore, the worm drive 140 can be connected to the gear box 144 or the gear motor 145. Prevents application of axial force.

I'll add some better diagrams.

[0039] FIG. 2E is another diagram showing the internal components of racing engine 10. In this case, the worm gear 150 is connected to the indexing wheel 151. (also known as the Geneva wheel 151) As explained in more detail below, the indexing wheel Rule 151 is used to home the drive mechanism in case of electrical or mechanical failure and loss of position. In this example, the racing engine 10 also provides a mechanism for returning the a wireless charging interconnect 165 and a wireless charging coil 166, They are located below the battery 170 (not shown in this view). In this example, the wireless charging coil 166 is located at the bottom 1 It is mounted on the outer underside of 04.

[0040] FIG. 2F is an illustrative cross-sectional view of racing engine 10 according to an exemplary embodiment. 2F illustrates the structure of the spool 130 as well as how the race grooves 132 and and how the raceway groove 110 interfaces with the raceway cable 131. As shown in this example, the race 131 is positioned in the race groove 11. 0 and runs continuously into the race groove portion 132 of the spool 130. The clear view shows the race recess 135 and the spool midsection, which are connected to the race 131. When the spool 130 is rotated to wind the lace 131, the lace 131 is wound over the spool 130. The spool middle section 137 is disposed below the top surface of the spool 130. The race recess 135 is formed by the top of the spool 130. The top of the spool 130 is in contact with the spool recess 115, the side of the spool recess 115, and and floor, as well as a radially extending spool member 137 substantially filling the spool midsection. In some examples, the top of the spool 130 extends beyond the spool recess 115. In other examples, the spool 130 may be completely inserted into the spool recess 115. The radial upper portion of the spool recess 115 fits over the side wall of the spool. The race 130 is allowed to rotate freely by the spool recess 115. 1 runs across the racing engine 10 and is captured by the racing groove portion 132, This allows the race 131 to slide into the race recess 135 when the spool 130 is rotated. It is adapted to be rotated onto the body of the spool 130 .

[0041] As illustrated by the cross section of the racing engine 10, the spool 130 The spool shaft 133 passes through an O-ring 138 and then In this example, the spool shaft 133 is connected to the spool gear 150 via a connecting pin 134. In some examples, the connecting pin 134 is connected to the spool. It extends in only one axial direction from the shaft 133, and the direction of the worm gear 150 is When reversed, most of the worm gear 150 rotates before the contact pin 134 is contacted. It is contacted by a key on the worm gear to allow full rotation. Also, a clutch system is implemented to couple the spool 130 to the worm gear 150. In such an example, the clutch mechanism may be configured to The connecting pin 134 can be actuated to allow the spool 130 to rotate freely. In the example where the spool extends in only one axial direction from the spool shaft 133, the spool While the wheel gear 150 is driven in reverse, it moves freely during the initial operation of the relaxation process. During the initial part of the relaxation process, the spool 130 is allowed to move freely. Allowing this to happen helps prevent tangling of the lace 131. It provides time for the user to begin loosening the footwear, which then , which applies tension in a direction that loosens the race 131 before being driven by the worm gear 150. This is because it will be
