The first base portion and the second base portion are held to the pedal platform, and the loop portion is perpendicularly spaced from the pedal platform. The belt and the pedal platform define an opening to receive a user's foot, and the rotation adjuster is rotatable about a rotation axis to adjust the circumference of the opening.

Description

[0001] Cross-reference to related applications

[0002] This application claims priority to U.S. Patent Application No. 18 / 117,265, filed on March 3, 2023. Technical Field

[0003] This invention relates to a system for securing a user's foot to a pedal or other foot support platform, wherein a "toe strap" is used to position and / or secure the rider's foot to the platform. The toe strap and the platform cooperate to provide an opening for receiving the user's foot. The effective length of the toe strap can be adjusted by rotating an adjuster, such that manual rotation of the adjuster changes the size of the opening, and thus changes the fit between the toe strap and the foot. The system may have a looser fit to aid in positioning the foot on the platform, a tighter fit for securing the foot to the platform, or a looser fit to facilitate insertion into and / or removal of the foot from the opening. Background Technology

[0004] It is well known that securing and / or positioning a cyclist's foot to the pedals helps ensure safety by preventing the foot from slipping off the pedals and by improving pedaling smoothness and efficiency. This has traditionally been achieved using conventional toe straps and toe clips. U.S. Patent Application No. 2012 / 0137826 (Figures 2, 3, and 5) describes an example of such a conventional toe strap configuration. The effective length of these conventional toe straps is typically adjustable via fasteners. However, these fasteners are notoriously difficult for the user to reach (while seated) for manual operation and for releasing the foot from the pedals. Furthermore, the fasteners are not very intuitive to operate and require some training from the user. Many users find the fasteners difficult to operate and adjust precisely while seated on the bicycle.

[0005] In other applications, particularly stationary bicycle pedals, the toe clip is omitted, and only a toe strap is included. U.S. Patent No. 6,393,941 (Figure 1) describes an example of this conventional configuration using only a toe strap. The effective length of this toe strap is typically engaged by one of several holes along the length of the strap with a single protrusion on the pedal platform. Once engaged, the length of the strap is fixed and not easily adjustable. This is generally an inefficient application and does not allow the user to easily tighten or loosen the strap while the user's foot is positioned on the platform. Therefore, this type of configuration is typically used only to position the foot on the pedal and not to secure the foot to the pedal platform. Furthermore, the protrusion and hole adjustment configuration limits the effective strap length adjustment to one of a series of discrete lengths and cannot be adjusted indefinitely. Therefore, it is difficult to achieve the optimal opening size and fit the user's foot. In addition, by omitting the toe clip, this configuration does not provide any forward positioning restriction or control between the foot and the platform. Furthermore, this configuration does not provide a precise fit and may require several attempts to find a comfortable and safe adjustment, necessitating repeated untying and re-tying of the straps.

[0006] In other applications utilizing only toe clips, the clips may include a loop section with a hook-and-loop or Velcro® closure. The effective length of the clip is adjusted by tearing and repositioning the Velcro engagement. However, this length adjustment is difficult and cumbersome. Furthermore, the Velcro engagement tends to wear down after several adjustments, leading to safety issues due to weakened closure strength. Similarly, by omitting the toe clip, this configuration provides no forward positioning restriction or control between the foot and the platform. Moreover, the Velcro function is susceptible to impairment when contaminated with dust.

[0007] In other applications where a "clipless" configuration is preferred, omitting both toe clips and straps, the user's shoe sole includes spikes attached to it. These spikes engage with mating connectors on the pedals or platform. This configuration securely connects the user's foot to the platform but does not allow the user to easily remove their foot from the pedal in a backward direction. Therefore, this configuration may deter users who fear they may not be able to relax their feet as desired.

[0008] Furthermore, this configuration requires an investment in special cycling shoes with spikes and dedicated pedals. Moreover, many users report difficulty in attaching to and detaching from these clipless pedals. Additionally, the shoes often do not perform well for other activities such as walking, running, or using other sports equipment.

[0009] Therefore, the object of the present invention is to overcome the aforementioned disadvantages and to provide an improved configuration for holding and / or fixing the user's feet to the pedal or foot platform. Summary of the Invention

[0010] The present invention utilizes a rotatable adjuster that can be manipulated about a rotation axis to increase or decrease the effective length of the toe strap and correspondingly change the size of the opening for receiving the user's foot and / or adjusting to fit the user's foot.

[0011] The rotatable adjuster can be positioned on the top center of the user's foot, making it easier for the user to reach with their hand when sitting on a bicycle or similar machine with pedals, without needing to look down.

[0012] Furthermore, the rotatable adjuster is intuitive and easy to operate. Users simply need to rotate the adjuster in one direction to tighten the strip and in the opposite direction to loosen it. This is a common operation familiar to most users.

[0013] Furthermore, the rotatable adjuster allows for precise adjustment to achieve a perfect fit between the user's foot and the pedal assembly. This provides the user with precise control over the positioning and / or tightness of their foot and pedal for optimal performance and / or user comfort.

[0014] In addition, the rotatable adjuster may include a quick-release mechanism that instantly expands the foot enclosure area, allowing the user to quickly remove their foot from the pedal.

[0015] Further features of the invention will become apparent from consideration of the drawings and the following description. Attached Figure Description

[0042] Figures 1a to 1cThe exemplary pedal assembly 1 is described, comprising a pedal 3, a strap 10, and a toe clip 30. The pedal 3, shown herein, has a generally known configuration, including a pedal body 2 for contacting a platform surface 4 with the user's foot (not shown), and protrusions 6 for creating a configured surface thereon to enhance grip and retention with the user's foot (compared to a smooth surface). For purposes defined herein, the term "platform surface" refers to the surface or plane of the pedal body 2 that supports the sole of the user's foot, regardless of the pedal type or its construction. The pedal body 2 is rotatable about a spindle 8 and about an axial axis 9. The spindle 8 includes an externally threaded boss 7 that is conventionally threaded to the crank arm of a bicycle (not shown). The pedal body 2 includes lugs 11a and 11b on its underside 5, which serve to retain the loop of the strap 10.

[0043] The toe clip 30 has a function similar to that of a conventional toe clip. It has a base portion (covered) conventionally held to the pedal body 2, and toe stops 32a and 32b that act as limiting stops to position the user's foot within the pedal assembly 1 and restrict its forward movement. The toe clip 30 further functions as an auxiliary connection between the pedal body 2 and the strip 10 in the area near the vertically upward apex of the strip 10. The toe clip 30 also includes an adjuster assembly 20 for receiving the first portion 12a and the second portion 12b of the strip 10.

[0044] The strip 10 includes a first portion 12a and a second portion 12b, both of which are fastened and / or held to the pedal body 2 adjacent to their respective base portions 14a and 14b by any of various methods known in the industry. The strip 10 is shown herein to be held and engaged directly to the pedal body 2. The strip 10 is considered an elongated element having an effective elongation length along an elongation axis, extending axially along a portion of the strip 10 between the base portions 14a and 14b and used to encircle the user's foot. The "effective length" of the strip is defined herein as the length of the portion of the strip contributing to the circumference of the opening. The strip 10 includes a loop portion 13 extending between its anchor point at the base portion 14a and its anchor point at the base portion 14b opposite to the pedal body 2. The first portion 12a and the second portion 12b include respective end portions 16a and 16b that overlap each other and interface with the adjuster assembly 20. The terms "strap" and "toe strap" are used interchangeably throughout this instruction manual.

[0045] like Figure 1bAs shown, the strip 10 is a continuously elongated element that surrounds the bottom side 5 of the pedal body 2 and passes through lugs 11a and 11b. It should be understood that this is only one representative method of holding the strip 10 to the pedal body 2. Lugs 11a and 11b act as circumferentially extending (covered) openings therein to receive circulation of the strip 10 passing through. These lugs 11a and 11b act as retaining members for holding the strip 10 and for limiting displacement along the vertical axis 54 and the longitudinal axis 50. However, lugs 11a and 11b may allow the strip 10 to slide to a certain extent in the circumferential direction 58. A wide range of alternative configurations are contemplated, including additional retaining members that hold the strip 10 circumferentially to the pedal body 2. Other alternative configurations are also contemplated, including a minimal retaining configuration that simply surrounds the bottom side 5 without lugs 11a and 11b. The most important requirement for this type of retention is that the strap can be used to retain the user's foot, especially in the vertical upward direction 56, on the platform surface by limiting the displacement between the user's foot and the platform surface 4.

[0046] The following are some directions and orientation conventions referenced throughout this instruction manual. The longitudinal axis 50 is generally along the length of the user's foot and is typically perpendicular to the axial axis 9. The longitudinal forward direction 52 is along the longitudinal axis 50 extending from the user's heel towards their toes. The longitudinal backward direction 53 is relative to the longitudinal forward direction. The transverse axis 55 is generally perpendicular to the longitudinal axis 50 and typically parallel to the axial axis 9. Lateral inward orientation indicates an orientation close to the transverse midpoint of the pedal body 2, and lateral outward orientation indicates an orientation away from the midpoint of the pedal body 2. The vertical axis 54 extends in a direction generally perpendicular to both the longitudinal axis 50 and the transverse axis 55. The vertical upward direction 56 extends generally inward and perpendicular to the platform surface, while the vertical downward direction 57 is relative to the vertical upward direction 56.

[0047] The strip 10, platform surface 4, and toe clip 30 cooperate to define an opening 40 for receiving the user's foot (not shown) in a conventional manner, wherein the opening 40 has an opening circumference 42, such as Figure 1b As shown. Circumferential direction 58 is an arc-shaped vector extending along the circumference of the opening 42. Tangential direction 59 is a straight vector approximately tangential to the circumference of the opening 42 at any point on it. Radial direction 60 is a direction perpendicular to tangential direction 59.

[0048] The adjuster assembly 20 includes a sleeve portion 34, which is an integral part of the toe clip 30. The sleeve portion 34 includes receiving end portions 16a and 16b through a circumferentially extending opening 36 therethrough, and a rotary adjuster 22. The rotary adjuster 22 is rotatable relative to the toe clip 30 and the strap 10 about a rotation axis 23. Figures 1d to 1eAs shown, the rotary adjuster 22 includes a knob portion 24 and a pinion portion 25 that acts as a pinion in the rack and pinion engagement shown. End portions 16a and 16b each include an elongated opening, each containing rack teeth 18a and 18b. An opening 36 guides and maintains the alignment of end portions 16a and 16b therein, and also maintains the engagement between the pinion portion 25 and the rack teeth 18a and 18b. The sleeve portion 34 also includes a shielded through-hole for guiding and maintaining the alignment of the rotary adjuster 22 engaged thereto, allowing for free rotation.

[0049] The rotation of the rotary adjuster 22 in the clockwise direction 26a actively drives the pinion portion 25 to engage with the rack teeth 18a and 18b, causing the end portions 16a and 16b to be driven in their respective directions 27a and 27b. This increases the circumferential overlap 19 between the end portions 16a and 16b, thereby reducing and shortening the opening perimeter 42 and correspondingly reducing the area of ​​the opening 40. Conversely, the rotation of the rotary adjuster 22 in the counterclockwise direction 26b reduces the circumferential overlap 19 between the end portions 16a and 16b and actively drives the end portions 16a and 16b in a direction relative to directions 27a and 27b. This expands and lengthens the opening perimeter 42 and correspondingly increases the area of ​​the opening 40. Therefore, the rotation of the rotary adjuster 22 is used to selectively adjust the fit between the strip 10 and the user's foot in a tightening orientation where the strip 10 radially approaches or slightly narrows the user's foot, and a loosening orientation where the strip 10 includes clearance with the user's foot. The benefits of such adjustments are well known in the industry and are based on prior art configurations.

[0050] The rotary adjuster 22 (including the knob portion 24) rotates about a rotation axis 23, which extends here in a generally radial and vertically upward direction and correspondingly perpendicular to the extension axis of the strip 10. Compared to prior art designs, the knob portion 24 is positioned adjacent to the vertically upward apex of the strip 10 and protrudes significantly upward and away from the pedal body 2, where the fastener is vertically lower and closer to the pedal body. This protrusion orientation results in a shorter reach for the user sitting on the corresponding bicycle (not shown), allowing the user to adjust the rotary adjuster 22 more easily. It should be noted that the rotary adjuster 22 and the adjuster assembly 20 are anchored in the toe clip 30, which can be considered a third element in addition to the pedal 3 and the strip 10.

[0051] Figures 2a to 2e describe Figures 1a to 1e The sequential steps of operating the pedal assembly, wherein the user engages his foot 38 with the pedal assembly 1 and / or disengages his foot from the pedal assembly. Figure 2a The user's foot 38 is positioned and aligned for engagement with the pedal assembly 1. Figure 2bThe foot 38 is then moved forward in a longitudinal forward direction 39a, so that the toe portion enters the opening 40 until it contacts the toe stops 32a and 32b. The strap 10 is positioned to circumferentially encircle the forefoot / midfoot area 43 of the user's foot. Next, the adjuster 22 is rotated as follows... Figure 2c The strip 10 is rotated in direction 26a to selectively reduce the opening circumference 42 to a tightening orientation, causing the toe clip 30 to bend in direction 41a, allowing the strip 10 and toe clip 30 to retract over the forefoot region 43 of the foot 38. In some cases, the user can adjust the rotation adjuster so that the strip 10 only slightly contacts the foot 38, or has a small clearance with the foot 38, allowing the user to easily slide off and disengage from the pedal assembly 1 in direction 39b. In other cases, the user may prefer a comfortable and slightly retracted fit between the strip 10 and the foot, which limits disengagement of the foot 38 and more actively positions the foot 38. Preferably, the strip 10 is positioned to circumferentially wrap around and interface with the forefoot / midfoot region 43 of the user's foot. This is the optimal position to provide stability to the interface between the foot 38 and the pedal assembly 1, while also importantly providing freedom of movement for the user's ankle. During cycling, the ankle joint is known to be a key aspect of efficient pedaling technique.

[0052] Next, in order to retract the foot from the pedal assembly 1, the user first... Figure 2d As shown, rotating the rotary adjuster 22 in direction 26b selectively increases the opening circumference 42 to loosen the orientation, which also relaxes the toe clip 30 to flex in direction 41b. This is used to relax any aforementioned contraction and allow the foot 38 to easily disengage from the pedal assembly 1 in the rearward direction 39b, so that the following... Figure 2e The foot is released from the pedal assembly 1. When the foot is removed from the pedal body 2, the strap 10 and toe clip 30 (which can be considered as the foot holding system of the pedal assembly 1) remain connected to the pedal body. The foregoing sequence of steps can be applied to any of the embodiments described herein.

[0053] Figures 3a to 3b The description includes an exemplary pedal assembly 65 comprising pedal 64 and a strip 75. Pedal 64 includes a pedal body 66 having a platform surface 67 for contact with the user's foot (not shown). Pedal body 67 is rotatable about a spindle 68 and about an axial axis 9. Spindle 68 includes an externally threaded boss that is conventionally threaded to a crank arm of a bicycle (not shown). Pedal body 66 includes a sleeve portion 69 having a boss 71 and an opening 70 therethrough for receiving a strip 75, as shown. Relative to Figures 1a to 1e Example of an implementation, Figures 3a to 3b The embodiments shown here do not include toe clips.

[0054] The strip 75 includes: a base portion 76 which is held or otherwise connected to the pedal body 66 by any of various methods known in the industry; an end portion 77 extending through the opening 70; and a swivel adjuster 80. The strip 75 is considered an elongated element having an elongated length along an elongation axis, extending along a portion of the strip 75 between the base portion 76 and the end portion 77. A loop portion 79 of the strip 75 is considered a portion of the strip 75 between its connection point to the pedal body 66 at the base portion 76 and its relative anchoring point to the pedal body 66 via the boss 71, the rope 83, and the swivel adjuster 80. The strip 75 and the platform surface 67 cooperate to define the opening 86 for receiving the user's foot (not shown) in a conventional manner, and include an opening circumference 87, such as... Figure 3b As shown.

[0055] The rotary adjuster 80 is an assembly whose knob portion 82 is rotatable relative to the strip 75 about a rotation axis 81. The knob portion 82 is connected to a reel portion (concealed) that acts as a pulley for winding the rope 83 thereon. The rotary adjuster 80 represents various reel and rope systems known in the industry, such as the Boa® system. The rope 83 includes a rope loop connecting the boss 71 and the reel portion. The strip 75 includes a loop or guide 78 for aligning and guiding the rope 83 relative to the strip 75. Rotation of the knob portion 82 about the rotation axis 81 in a clockwise direction 84a winds, engages, and tightens the rope 83 on the reel portion, effectively reducing the exposed length of the rope 83 to pull the rotary adjuster 80 toward the boss 71, thereby actively pulling the strip 75 across the opening 70 in the direction 85a. This correspondingly reduces and shortens the opening circumference 87 and correspondingly reduces the area of ​​the opening 86. The rope 83 can be considered as a portion of the loop portion 79 extending between the base portion 76 and the boss 71. The end portion 77 is used to guide the strip 75 through the opening 70.

[0056] The knob portion 82 rotates about the rotation axis 81, which extends here via an elongation axis shown generally radially and correspondingly perpendicular to the strip 75. Unlike Figures 1a to 1e In one embodiment, the rotary adjuster 80 is anchored to the strip 75 at a position offset from the vertically upward vertex of the strip 75.

[0057] Rotation of the knob portion 82 in the counterclockwise direction 84b is used to unwind and loosen the rope 83, allowing the rope to extend away from it to increase the circumferential distance between the rotary adjuster 80 and the boss 71. The strip 75 can now be operated by the user to extend and enlarge the loop portion 79 and correspondingly increase the opening circumference 87, and to pull the end portion 77 across the opening 70 in the direction 85b to correspondingly increase and lengthen the opening circumference 87 and correspondingly increase the area of ​​the opening 86. Depending on the stiffness and design of the strip 75, the loop portion 79 can be easily sprung open without manual operation. Since the rope 83 contains a cord, it is effective at bearing tensile loads, but less effective at bearing compressive loads. Rotation of the rotary adjuster 80 is used to selectively adjust the circumferential fit between the strip 75 and the user's foot (not shown) in a tightening orientation for contracting or holding the user's foot, and a loosening orientation for the user's foot to release from the pedal assembly 65. An example of this rotary adjuster configuration was found in the Boa® "S Series" model of rotary adjusters.

[0058] In an alternative rotary adjuster configuration, instead of rotating the knob portion in direction 84b, the user only needs to pull the knob portion 82 upwards to shift it relative to the strip 75 in direction 88. This releases the grip in the reel and allows it to passively unwind and loosen the rope 83. In this configuration, rotation of the rotary adjuster 80 in direction 84a selectively adjusts the circumferential fit between the strip 75 and the user's foot (not shown) to a tightening orientation, while non-rotational manipulation of the rotary adjuster 80 adjusts the circumferential fit between the strip 75 and the user's foot (not shown) to a loosening orientation where the user's foot can be released from the pedal assembly 65. Examples of this rotary adjuster configuration are found in Boa® "M Series" models of rotary adjusters.

[0059] In this paper, the term "active" refers to a situation where the rotary adjuster is actively coupled to the strip, causing its rotation to correspondingly shift the strip and change the length of the opening circumference. Conversely, the term "passive" refers to a situation where the rotary adjuster is passively coupled to the strip, causing its rotation only to loosen the strip's position, requiring the application of external force to change the length of the opening circumference. Figures 3a to 3b In one example, rotation of the knob portion 82 in direction 84a increases the tension in the rope 83 to actively drive the strip 75 in direction 85a, while rotation of the knob portion 82 in direction 84b only extends and reduces the tension in the rope 83 to passively relax the strip 75, requiring an external force in direction 85b (i.e., by user manipulation to widen the opening 86) to displace the end portion 77 in direction 85b. Alternatively, the strip 75 may have sufficient springback to widen the opening 86 without requiring user manipulation.

[0060] Figures 4a to 4b The exemplary pedal assembly 105 is described, which includes a pedal 104, a strip 115, and a rotation adjuster 120. The pedal 104 includes a pedal body 106 having a platform surface 107 for contacting a user's foot (not shown), and includes a protrusion 111 for creating a configurable surface thereon to increase grip and engagement with the user's foot (compared to a smooth surface).

[0061] The pedal body 107 is rotatable about a spindle 108 and about an axial axis 9. The spindle 108 includes an externally threaded boss that is conventionally threaded to a crank arm of a bicycle (not shown). The pedal body 106 includes a sleeve portion 109 having an opening 110 therethrough to receive a belt 115 passing through it. The opening 110 guides and maintains alignment of the end portion 117 therethrough and also maintains engagement between the pinion portion (covered) and the rack teeth 119. Relative to Figures 1a to 1e Example of an implementation, Figures 4a to 4b The embodiments shown here do not include toe clips.

[0062] The strip 115 includes: a base portion 116 held or connected to the pedal body 106 by any of various methods known in the industry; and an end portion 117 extending through the opening 110 and having an elongated opening 118 with rack teeth 119. The strip 115 is considered an elongated element having an elongated length between the base portion 116 and the end portion 117. The loop portion 123 of the strip 115 is considered a portion of the strip 115 between the base portion 116, its gear engagement with the rotary adjuster 120 via rack teeth 119, and its relative anchor point to the pedal body. The strip 115 and the platform surface 107 cooperate to define the opening 126 together with the opening circumference 127 to receive the user's foot (not shown) in a conventional manner, as... Figure 4b As shown.

[0063] The rotary adjuster 120 is rotatable relative to the strip 115 about a rotation axis 121. The rotary adjuster 120 includes a knob portion 122 connected to a pinion (not shown), which acts as a pinion in a rack and pinion engagement as shown. The sleeve portion 109 also includes a shielded through-hole for guiding and maintaining the alignment and free rotation of the rotary adjuster 120 engaged thereto. The rotary adjuster 120 is shown here as being held, coupled, or otherwise anchored to the pedal body 106 and is rotatable about a rotation axis 121 extending in a generally lateral direction.

[0064] Rotation of the knob portion 122 in a clockwise direction 124a about the rotation axis 121 actively drives the gear engagement between the pinion and rack teeth 119, causing the end portion 117 to be driven relative to the sleeve 109 and the pedal body 106 in a direction 125a. This reduces and shortens the opening circumference 127 and correspondingly reduces the area of ​​the opening 126. Conversely, rotation of the knob portion 122 in a counterclockwise direction 124b actively drives the end portion 117 in a direction 125b. This expands and lengthens the opening circumference 127 and correspondingly increases the area of ​​the opening 126. Therefore, rotation of the rotary adjuster 120 selectively adjusts the circumferential fit between the strap 115 and the user's foot in a tightening orientation for positioning control between the user's foot and the pedal assembly 105, and a loosening orientation for the user's foot to release from the pedal assembly 105.

[0065] Figures 5a to 5b The description describes an exemplary pedal assembly 155, which includes a pedal 154 and a belt assembly. The belt assembly includes a first belt portion 167, a second belt portion 168, and a swivel adjuster 170. The pedal 154 includes a pedal body 156 having a platform surface 157 for contacting a user's foot (not shown), and includes a protrusion 161 for creating a configurable surface thereon to enhance grip and engagement with the user's foot (compared to a smooth surface). The pedal body 157 is rotatable about a spindle 158 and about an axial axis 9. The spindle 158 includes an externally threaded boss that is conventionally threaded to a crank arm of a bicycle (not shown).

[0066] The first strip portion 167 includes: base portions 166a and 166b, which are held or connected to the pedal body 156 by any of various methods known in the industry; a circulation portion 165, which is spaced apart from the platform surface 157 between the base portions 166a and 166b; and an internally threaded hole 179 for threadedly receiving the external thread of the rotary adjuster 170. The first strip portion 167 is considered as an elongated element having an elongated length between the base portions 166a and 166b. The second strip portion 168 includes a receiving surface 181 for contacting with the user's foot (not shown), and a socket for receiving the radially inner end of the rotary adjuster 170.

[0067] The rotary adjuster 170 includes a knob portion 172 and an externally threaded shaft 173 having a radially inner end 180. The shaft 173 has a helical engagement with an internally threaded hole 179 in a first strip portion 167, and the end 180 adapts to a socket in a second strip portion 168. The first strip portion 167, the second strip portion 168, and the platform surface 157 cooperate to define an opening 176 for receiving a user's foot (not shown) in a conventional manner, and includes an opening circumference 177, such as... Figure 5b As shown.

[0068] The rotary adjuster 170 is rotatable about a rotation axis 171 relative to the first strip portion 167. The rotary adjuster 120 is shown here anchored to the first strip portion 167, wherein the rotation axis 171 extends in a generally radial direction. Compared to prior art designs, the knob portion 172 is positioned adjacent to the vertically upward apex of the first strip portion 167 and protrudes significantly upward and away from the platform surface 157.

[0069] Rotation of the knob portion 172 in the clockwise direction 174a actively tightens and drives the threaded engagement between the threaded shaft 173 and the hole 179, causing end 180 to abut against the socket, thereby driving the second strip portion 168 radially inward toward the platform surface 157 in the direction 175a. This reduces and shortens the opening circumference 177 and correspondingly reduces the area of ​​the opening 176. Conversely, rotation of the knob portion 172 in the counterclockwise direction 174b disengages the aforementioned helical engagement, allowing the second strip portion 168 to move radially outward in the direction 175b. This expands and lengthens the opening circumference 177 and correspondingly increases the area of ​​the opening 176. Therefore, rotation of the rotary adjuster 170 selectively adjusts the circumferential fit between the strip assembly and the user's foot in a tightening orientation and a loosening orientation where the user's foot can be released from the pedal assembly 155. Figures 5a to 5b The arrangement is schematically depicted in which the second strip portion 168 can be radially displaced relative to the first strip portion 167 using a rotary adjuster 170. This is relative to... Figures 1a to 1e The first (strip) portion 12a can be circumferentially shifted relative to the second (strip) portion 12b using a rotation adjuster 22.

[0070] Figures 6a to 6b The description describes an alternative rotatable adjuster assembly 130 that can replace some of the other rotatable adjusters described above. The rotatable adjuster assembly 130 includes a first belt portion 132, a second belt portion 134, and a rotatable adjuster 136. The first belt portion 132 includes rack teeth 138 on its radially outward surface to engage with gear teeth 149 of a pinion 148. The second belt portion 134 includes flanges 142a and 142b that laterally span the first belt portion 132 and also include a hole (covered) to receive the rotatable adjuster 136 and allow rotation between them about a rotation axis 131. Flanges 142a and 142b also include guide surfaces 144a and 144b, respectively, to provide alignment and guidance of the first belt portion 132 between them. The rotatable adjuster 136 includes a knob portion 146 and a pinion 148 having gear teeth 149. The first strip portion 132 is radially confined between the pinion 148 and the second strip portion 134 to maintain gear engagement between the gear teeth 149 and the rack teeth 138.

[0071] Rotation of the knob portion 146 in the counterclockwise direction 150b about the rotation axis 131 rotates the pinion 148 and drives the gear teeth 149 to engage with the rack teeth 138, causing the end portion 140 to be actively driven in the direction 148b to increase the circumferential overlap between the first strip portion 132 and the second strip portion 134, thereby reducing and shortening the opening circumference 152 as described above. Conversely, rotation of the knob portion 146 in the clockwise direction 150a actively drives the end portion 140 relative to the second strip portion 134 in the direction 148a, and correspondingly reduces the circumferential overlap between the first strip portion 132 and the second strip portion 134. This is used to expand and lengthen the opening circumference 152. Therefore, this adjustment of the opening circumference 152 has similarity to that described above. Figures 6a to 6b An example of a rotary adjuster 136 rotating about a rotation axis 131 extending in a generally longitudinal direction is described. The rotary adjuster 136 is shown here anchored in a second strip portion 134.

[0072] Figures 7a to 7b The description describes an alternative rotatable adjuster assembly 230 that can replace some of the other rotatable adjusters described above. The rotatable adjuster assembly 230 includes a first belt portion 232, a second belt portion 234, and a rotatable adjuster 236. The first belt portion 232 includes rack teeth 238 on its radially outward surface to engage with a worm protrusion 249 of a worm gear 248. The second belt portion 234 includes a bracket 242 that laterally spans the first belt portion 232 and also includes a hole (covered) to receive the rotatable adjuster 236 and allow rotation between them about a rotation axis 231. The bracket 242 also includes a guide surface 244a to provide alignment and guidance of the first belt portion 232 between them. The rotatable adjuster 236 includes a knob portion 246 and a worm gear 248 having a worm protrusion 249. The first strip portion 232 is radially confined between the worm 248 and the second strip portion 234 to maintain gear engagement between the worm protrusion 249 and the rack teeth 238. It should be noted that the rotatable adjuster assembly 230 is similar to the adjusting assembly of a worm-driven hose clamp known in the industry.

[0073] The rotation of knob portion 246 in the clockwise direction 250a around the rotation axis 231 actively actuates the gear engagement between the rotation adjuster 236 and the worm gear cam 249 and the rack teeth 238, causing end portion 240 to be actively driven in the direction 251a to increase the circumferential overlap between the first strip portion 232 and the second strip portion 234, thereby reducing, shortening, and closing the opening circumference 252 as described above. Conversely, the rotation of knob portion 26 in the counterclockwise direction 250b reduces the circumferential overlap between the first strip portion 232 and the second strip portion 234, and actively drives end portion 240 in the direction 251b relative to the second strip portion 234. This expands, lengthens, and opens the opening circumference 252. Therefore, this adjustment of the opening circumference 252 is similar to that described above. Figures 7a to 7b An exemplary embodiment is described in which the rotary adjuster 236 rotates about a rotation axis 231 extending in a generally tangential direction. The rotary adjuster 236 is anchored in a second strip portion 234.

[0074] Figures 8a to 8b The description describes an alternative rotatable adjuster assembly 190 that can replace some of the other rotatable adjuster assemblies described above. The rotatable adjuster assembly 190 includes a first belt portion 192, a second belt portion 194, and a switching link 196. The first belt portion 192 includes an end portion 193 having a pivot pin 197a extending along a pivot 198a. The second belt portion 194 includes an end portion 195 having a pivot pin 197b extending along a pivot 198b. The switching link 196 includes a tab handle 199 and arms 200a and 200b for longitudinally spanning the end portions 193 and 195, and also includes holes 201a and 201b through which they pass. Holes 201a and 201b respectively receive pins 197a and 197b to establish a first hinge engagement around pivot 198a between switching link 196 and end portion 193, and a second hinge engagement around pivot 198b between switching link 196 and end portion 195.

[0075] like Figures 8a to 8b The switching linkage 196 has rotated clockwise about pivot 198b in direction 203a. This rotation causes the first strip portion 192 to shift in direction 205a, such that end portion 193 circumferentially overlaps end portion 195. This is considered a closed or tightened orientation of the adjuster assembly 190, wherein the circumferential length of the adjuster assembly 190 is shortened, and wherein the first strip portion 192 is close to the second strip portion 194 and corresponds to the shortened opening circumference 207.

[0076] Next, as Figures 8c to 8dAs shown, the switching link 196 is rotatable about a pivot 198b in a counterclockwise direction 203b. This causes the first strip portion 192 to shift in direction 205b, such that the end portion 193 is circumferentially spaced from the end portion 195. This is considered an open or closed orientation of the adjuster assembly 190, wherein the circumferential length of the adjuster assembly 190 is increased, and wherein the first strip portion 192 is moved away from the second strip portion 194 and corresponds to an expanded and lengthened opening circumference 207. The adjuster assembly 190 can be considered as a switching link mechanism known in the industry, wherein the switching link is circumferentially fixed and pivots relative to both end portions 193 and 195. The switching link 196 acts as a rotary adjuster that rotates about a pivot 198b, which is shown here extending in a generally longitudinal direction. The switching link 196 is anchored to both the first strip portion 192 and the second strip portion 194.

[0077] It should be noted that the switching link 196 acts as a rotary adjuster that rotates approximately 180 degrees about pivot 198b in directions 203a or 203b between the loosening and tightening orientations. It can be seen that rotation of the switching link 196 about pivot 198b at angles greater than 360 degrees is not feasible due to significant geometric constraints. Preferably, this rotation provides an "over-center" geometry in the closed orientation, where the switching mechanism will not adversely shift to the open orientation. This over-center geometry configuration is known in the industry. The restricted rotation of the switching link 196 (limited to at least less than 360 degrees) is relative to the rotary adjusters 22, 80, 120, and 170 corresponding to their respective embodiments, which do not have this geometric constraint and can rotate 360 ​​degrees or more between their respective tightening and loosening orientations. In fact, this larger rotation angle may be preferred because it provides greater mechanical advantages and / or more precise control over the length of the circumferential circumference.

[0078] While my above description contains many specific details, these should not be construed as limiting the scope of the invention, but rather as illustrative of its embodiments. For example:

[0079] The embodiments described herein show the strip as a separate element connected to and / or held to the pedal body. Alternatively, the strip and pedal body may be a single piece and / or molded as a continuous assembly.
