[0122] The load-bearing rack embodiments disclosed herein can be used with, for example, but not limited to, bicycle racks. More specifically, the load-bearing rack can include a vehicle-mounted bicycle rack, for example, a hook-mounted bicycle rack that can be attached to a vehicle's hook-on receiver. The rack can be configured to hold one, two, or more bicycles.

[0123] As discussed above, it is important to securely mount loads (such as bicycles) to the load carrier to reduce dynamic forces applied to the bicycle that can lead to instability and damage. Therefore, it is essential to have a load carrier that is easy to use, for example, operable with one hand, and has improved versatility to accommodate bicycles of different shapes and sizes and wheel diameters. Furthermore, with the increasing electrification of bicycles and the associated increase in weight, it is important to provide a load carrier capable of accommodating a wider range of weights and loads. To accommodate heavier loads, it is important that the wheel retaining arm is shaped and includes features that increase torsional stiffness to support the increased weight.

[0124] The implementation scheme of the load-bearing rack device discussed below can provide versatility for securing loads of different shapes and sizes, as well as improved ease of use for users loading and unloading bicycles onto and from the load-bearing rack.

[0125] Figures 1 to 26A load carrier 100 according to an embodiment is illustrated. The load carrier 100 may be configured to secure a load, such as a bicycle 102, using a wheel retaining arm 200 coupled to a wheel tray 120. In some embodiments, the wheel retaining arm 200 may be configured to rotate relative to the wheel tray 120 from a first position 10 (such as a closed configuration) to a second position 20 (such as a loaded configuration) to secure the wheel 104 of the bicycle 102 to the load carrier 100. In some embodiments, the load carrier 100 may include ratchet mechanisms 300, 500 configured to control the rotation of the wheel retaining arm 200 relative to the wheel tray 120. For example, when the ratchet mechanisms 300, 500 are engaged, rotation of the wheel retaining arm 200 is prevented in a first direction 30, but rotation is permitted in a second direction 40. In some embodiments, when the ratchet mechanisms 300, 500 are disengaged, the wheel retaining arm 200 is free to rotate in the first direction 30 and the second direction 40. In some embodiments, the load carrier 100 may include a wheel stop 400 configured to engage with a wheel 104 to secure the bicycle 102 to the load carrier 100.

[0126] The load-bearing frame 100 may include a base 110, a wheel tray 120, a hub 126, a wheel fixing arm 200, and a ratchet mechanism 300, for example, Figures 1 to 8 As shown. In some embodiments, the base 110 may include a tow bar 106 configured to secure the load carrier 100 to the vehicle. In some embodiments, the load carrier 100 may be a bicycle carrier 100, such that the wheels 104 of the bicycle 102 are supported by wheel trays 120 and secured by wheel retaining arms 200. In some embodiments, the load carrier 100 may be configured to secure one or more bicycles and includes at least one wheel tray 120 for each wheel 104 of the one or more bicycles 102 and at least one wheel retaining arm 200 for each of the one or more wheels 104. Figure 1 In the exemplary embodiment shown, the load carrier 100 includes four wheel trays 120 and four wheel retaining arms 200 to secure at least two bicycles to the load carrier 100.

[0127] exist Figure 1In the illustrated exemplary embodiment, wheel tray 120 may be coupled to a first side 112 and a second side 114 of base 110. In some embodiments, wheel tray 120 may extend generally perpendicularly from base 110. In some embodiments, wheel tray 120 may include a proximal end 122 and a distal end 124. The proximal end 122 of wheel tray 120 may be coupled to base 110. The distal end 124 may be opposite to the proximal end 122 and spaced apart from base 110. In some embodiments, wheel tray 120 may include a recess 125 extending from proximal end 122 to distal end 124 and sized to receive the wheel 104 of bicycle 102.

[0128] In some embodiments, the hub 126 may be coupled to the distal end 124 of the wheel tray 120, for example, as Figure 1 As shown in Figure 3B. In some embodiments, the hub 126 may be part of the wheel tray 120 and is located at the distal end 124 of the wheel tray 120. In some embodiments, the hub 126 may be an attachment point for the wheel retaining arm 200, such that the wheel retaining arm 200 rotates about an axis 128 extending through the hub 126. In some embodiments, the hub 126 may be substantially hollow and configured to receive at least a portion of the ratchet mechanism 300. Figure 1 In the exemplary embodiment shown in Figure 3B, the hub 126 has a cylindrical shape. In some embodiments, the hub 126 may have a polygonal cross-sectional shape.

[0129] The wheel retaining arm 200 can be attached to the wheel tray 120 at the hub 126, for example, as Figure 1 As shown in Figure 2B, the wheel retaining arm 200 can be configured to secure the wheel 104 to the load carrier 100. The wheel retaining arm 200 can be configured to rotate about axis 128 from a first position 10 to a second position 20. In some embodiments, the first position 10 can be a closed configuration such that the wheel retaining arm 200 is generally parallel to the wheel tray 120, for example, as shown in Figure 2A. In some embodiments, the second position 10 can be a loading configuration such that the wheel retaining arm 200 rotates outward away from the wheel tray 120 so that the bicycle 102 can be loaded onto the load carrier 100, for example, as shown in Figure 2B. In some embodiments, the wheel retaining arm 200 can be configured to rotate beyond the second position 20, beyond its parallel orientation relative to the wheel tray 120.

[0130] The wheel retaining arm 200 may include a distal end 230, a fixed end 232, a bridging member 235, a first arm 234, and a second arm 236, for example, as shown in Figures 2A and 2B. Figure 10As shown. In some embodiments, the wheel retaining arm 200 may be rotatably coupled to the wheel tray 120 at a fixed end 232. A pair of upright arms (e.g., a first arm 234 and a second arm 236) may extend from the fixed end 232 to the distal end 230. In some embodiments, a bridging member 235 may extend from the first arm 234 to the second arm 236 to join the first arm 234 and the second arm 236 together at the distal end 230. In some embodiments, the wheel retaining arm 200 may include an arm base 210 at the fixed end 232 of the first arm 234 and / or the second arm 236, for example, as shown in Figures 3A, 3B, 5A, 5B, 6A, and 6B. In some embodiments, the arm base 210 may be integral with either or both of the pair of upright arms 234, 236. In some embodiments, the arm base 210 may be coupled to the first arm 234 and / or the second arm 236 via welding, adhesive, fasteners, or any other suitable type of connection. In some embodiments, the arm base 210 may be coupled to the wheel tray 120 at the hub 126.

[0131] The arm base 210 may include a first side 212 and a second side 214 opposite to the first side 212, as shown, for example, in Figures 3A, 3B, 6A, and 6B. In some embodiments, the first side 212 may face outwards away from the wheel tray 120, and the second side 214 may face the wheel tray 120. In some embodiments, the first side 212 may include an edge 216 extending outwards away from the arm base 210. The edge 216 may include an indicator 220 to indicate whether the ratchet mechanism 300 is engaged or disengaged. In some embodiments, the indicator 220 may be a different color from the arm base 210, making it easily visible when not covered. In some embodiments, the indicator 220 may be yellow, red, or any other color that enhances the visibility of the edge 216 to the user. In some embodiments, the indicator 220 may include one or more lights spaced around the edge 216 and activated when the ratchet mechanism is engaged or disengaged.

[0132] In some embodiments, a cavity 218 may be formed in the arm base 210, for example, in the second side 214. In some embodiments, a portion of the ratchet mechanism 300 may be disposed in the cavity 218. In some embodiments, a portion of the arm base 210 may extend over and contact a portion of the hub 126, such that friction between the arm base 210 and the hub 126 slows the movement of the wheel fixing arm 200 along the first direction 30 and the second direction 40 when the wheel fixing arm 200 is moved relative to the wheel tray 120.

[0133] Ratchet mechanism 300 can be coupled to hub 126, for example, as shown in Figures 3A and 3B. Ratchet mechanism 300 can control the rotation of wheel retaining arm 200 relative to wheel tray 120. For example, when ratchet mechanism 300 is in engaged position 50, ratchet mechanism 300 can be configured to prevent wheel retaining arm 200 from moving in a first direction 30 (e.g., from first position 10 to second position 20) and allow wheel retaining arm 200 to move in a second direction 40 (e.g., from second position 20 to first position 10). In some embodiments, when ratchet mechanism 300 is in disengaged position 60, ratchet mechanism 300 can allow wheel retaining arm 200 to move freely in both the first direction 30 and the second direction 40.

[0134] The ratchet mechanism may include an actuator 302, a first toothed ring 304, a second toothed ring 306, a spring 308, and / or a spacer ring 310, as shown, for example, in Figures 3A to 6B. In some embodiments, the ratchet mechanism 300 may be at least partially disposed in the hub 126 and / or partially disposed in the cavity 218 of the arm base 210. In some embodiments, the ratchet mechanism 300 may be completely disposed within the hub 126, for example, as shown in Figures 7A and 7B. The actuator 302 may be configured to move the ratchet mechanism 300 from an engaged position 50 to a disengaged position 60. In some embodiments, the actuator 302 may be disposed on a first side 212 of the arm base 210.

[0135] In the exemplary embodiments shown in Figures 6A and 6B, the actuator 302 can translate away from and toward the arm base 210. In some embodiments, the actuator 302 can be coupled to the second toothed ring 306 via a plurality of fasteners 303. In some embodiments, the plurality of fasteners 303 extend through the arm base 210. In some embodiments, the actuator 302 can be moved away from the arm base 210 to move the ratchet mechanism 300 into a disengaged position 60. In some embodiments, the actuator 302 can be pulled away from the arm base 210 to move the ratchet mechanism 300 into the disengaged position 60. In some embodiments, the actuator 302 can hold the ratchet mechanism 300 in the disengaged position 60 so that a user can move the wheel retaining arm 200 while the ratchet mechanism 300 is disengaged. In some embodiments, friction between the fasteners 303 and the arm base 210 can temporarily hold the actuator 302 outward from the arm base 210, such that the ratchet mechanism is held in the disengaged position 60.

[0136] In some embodiments, actuator 302 may move toward arm base 210 to move ratchet mechanism 300 into engaged position 50, for example, as shown in Figures 5A to 6B. In some embodiments, when wheel retaining arm 200 is in second position 20, actuator 302 may be pushed toward arm base 210 to move ratchet mechanism 300 into engaged position 50. In some embodiments, when wheel retaining arm 200 is moved into second position 20, actuator 302 may automatically move from disengaged position 60 to engaged position 50.

[0137] In the exemplary embodiment shown in Figure 6B, when the ratchet mechanism 300 is in the engaged position 50, the actuator 302 extends over and covers the edge 216, making the indicator 220 invisible to the user. In the exemplary embodiment shown in Figure 6A, when the ratchet mechanism 300 is in the disengaged position 60, the actuator 302 moves away from the arm base 210 to expose the edge 216, making the indicator 220 visible to the user. The indicator 220 can be beneficial because it allows the user to quickly and easily see whether the ratchet mechanism 300 is disengaged and whether the bicycle 102 is not properly secured to the load carrier 100.

[0138] In the exemplary embodiments shown in Figures 3A, 3B, 5A, and 5B, a first toothed ring 304 is disposed in the hub 126. The first toothed ring 304 may include a plurality of teeth 320. In some embodiments, the plurality of teeth 320 of the first toothed ring 304 may be configured to engage a plurality of teeth 330 of a second toothed ring 306. In some embodiments, the plurality of teeth 320 may extend axially away from the first toothed ring 304 along axis 128. In some embodiments, the plurality of teeth 320 may extend radially away from the first toothed ring 304 and, for example, engage a pawl disposed in a cavity 218 of the arm base 210. In Figures 3A to 5B Figure 4 In the exemplary embodiment shown, the first toothed ring 304 includes a radial spline 322. In some embodiments, the radial spline 322 may be configured to engage with a corresponding internal spline 130 in the hub 126. The radial spline 322 and the internal spline 130 may be configured to prevent rotation of the first toothed ring 304 relative to the hub 126 while allowing axial translation of the first toothed ring 304 relative to the hub 126 along axis 128.

[0139] In the exemplary embodiments shown in Figures 3A, 3B, 5A, and 5B, a second toothed ring 306 is disposed in a cavity 218 of the arm base 210. The second toothed ring 306 may include a plurality of teeth 330 configured to engage a plurality of teeth 320 of the first toothed ring 304. In some embodiments, the plurality of teeth 320, 330 are angled such that when the ratchet mechanism 300 is in the engaged position 50, and the wheel retaining arm 200 moves in the second direction 40, the teeth 320, 330 may slide past each other, but the teeth 320, 330 are locked together and prevent rotation of the wheel retaining arm 200 in the first direction 30. In some embodiments, the plurality of teeth 330 may extend axially toward the hub 126 away from the second toothed ring 306. In some embodiments, the plurality of teeth 330 may extend radially away from the second toothed ring 306 and engage a pawl disposed in the cavity 218 of the arm base 210. (Figures 3A to 5B) Figure 4 In the exemplary embodiment shown, the second toothed ring 306 includes a radial spline 332. In some embodiments, the radial spline 332 may be configured to engage with a corresponding spline 222 in the cavity 218. The radial spline 332 and spline 222 may be configured to prevent rotation of the second toothed ring 306 relative to the arm base 210 while allowing axial translation of the second toothed ring 306 relative to the arm base 210 along axis 128. In some embodiments, an actuator 302 may be coupled to the second toothed ring 306 and configured to move the second toothed ring 306 away from the first toothed ring 304, such that the plurality of teeth 320, 330 disengage, and the ratchet mechanism is moved to the disengaged position 60.

[0140] In some embodiments, the plurality of teeth 320, 330 may include 60 to 200 teeth on each of the first toothed ring 304 and the second toothed ring 306. In some embodiments, the plurality of teeth 320, 330 may include 70 to 180 teeth on each of the first toothed ring 304 and the second toothed ring 306. In some embodiments, the plurality of teeth 320, 330 may include 80 to 110 teeth on each of the first toothed ring 304 and the second toothed ring 306. In some embodiments, the plurality of teeth 320, 330 may include 90 teeth on each of the first toothed ring 304 and the second toothed ring 306. The increased number of teeth can increase the angular engagement between the first toothed ring 304 and the second toothed ring 306, such that the distal end 230 of the wheel retaining arm 200 moves a shorter distance between the engagement of adjacent teeth of the plurality of teeth 320, 330 at the hub 126. In some embodiments, the number of teeth can be increased by increasing the diameter of the first toothed ring 304 and the second toothed ring 306. In some embodiments, the number of teeth can be increased by using narrower cutting teeth on the first toothed ring 304 and the second toothed ring 306, thereby reducing the pitch length of the plurality of teeth 320, 330.

[0141] In some embodiments, the ratchet mechanism 300 may include a third toothed ring radially inside the first toothed ring 304, such that both the first and third toothed rings engage the second toothed ring 304. In some embodiments, the third toothed ring may include a plurality of teeth offset from, for example, half a pitch length from, the plurality of teeth 320 of the first toothed ring 304, to effectively double the engagement with the plurality of teeth 330 of the second toothed ring 306.

[0142] In some embodiments, the spring 308 may be disposed between the first toothed ring 304 and the hub 126, for example, as shown in Figures 3A and 3B. In some embodiments, the spring 308 may be configured to bias the first toothed ring 304 toward and engage with the second toothed ring 306. In some embodiments, the spring 308 may be disposed in the cavity 218 of the arm base 210 and configured to bias the second toothed ring 306 toward the first toothed ring 304.

[0143] exist Figure 4In the exemplary embodiment shown in FIG5B, a spacer ring 310 may be disposed between the hub 126 and the arm base 210. In some embodiments, the spacer ring 310 may restrict the movement of the first toothed ring 304. For example, when the actuator 302 moves the second toothed ring 306 away from the first toothed ring 304 and into the disengaged position 60, the spacer ring 310 may prevent the first toothed ring 304 from following the second toothed ring 306, thereby creating a gap between the plurality of teeth 320, 330 of the first toothed ring 304 and the second toothed ring 306. In some embodiments, the spacer ring 310 extends above the open end 132 of the internal spline 130 in the hub 126 such that when the first toothed ring 304 reaches the outer boundary of the hub 126, the radial spline 322 of the first toothed ring 304 engages the spacer ring 310. In some embodiments, the spacer ring 310 prevents the first toothed ring 304 from moving further outward, so that the actuator 302 can move the second toothed ring 306 to disengage from the first toothed ring 304 and the ratchet mechanism 300 and enter the disengaged position 60.

[0144] For example, as shown in Figure 5A, the ratchet mechanism 300 is in the engaged position 50, such that the actuator 302 pushes the second toothed ring 306 toward the first toothed ring 304, and the toothed rings 304 and 306 are engaged. When the wheel retaining arm 200 moves along the second direction 40, the first toothed ring 304 can be axially translated away from the second toothed ring 306 as the teeth 320 and 330 slide past each other. After the teeth have slid, the spring 308 can bias the first toothed ring 304 back toward the second toothed ring 306. When the wheel retaining arm 200 moves along the first direction 30, the first toothed ring 304 is biased toward the second toothed ring 306 to lock and maintain the engagement between the teeth 320 and 330 to prevent rotation along the first direction 30. In the exemplary embodiment shown in Figure 5B, the ratchet mechanism 300 is in the disengaged position 60, such that the actuator 302 moves the second toothed ring 306 to disengage from the first toothed ring 304, creating a gap between the plurality of teeth 320, 330. The spring 308 biases the first toothed ring 304 outward, but the spacer ring 310 restricts the movement of the first toothed ring 304, maintaining the gap between the teeth 320, 330 and preventing engagement of the first toothed ring 304 and the second toothed ring 306.

[0145] In the exemplary embodiments shown in Figures 7A and 7B, the ratchet mechanism 350 is entirely disposed within the hub 126. The ratchet mechanism 350 may include a ratchet 352, a plurality of radially extending teeth 354, a plurality of pawls 356, and / or a ratchet body 358. In some embodiments, the plurality of teeth 354 extend radially away from the ratchet 352. In some embodiments, the plurality of pawls 356 are configured to engage with the plurality of teeth 354 when the ratchet mechanism 350 is in an engaged position. In some embodiments, the plurality of pawls 356 may be biased (e.g., spring-biased) to engage with the plurality of teeth 354. In some embodiments, the plurality of pawls 356 includes three pawls. In some embodiments, the plurality of pawls 356 includes fewer than three pawls or more than three pawls. In some embodiments, the plurality of pawls 356 are axially spaced along the length of the ratchet 352. In some embodiments, multiple pawls 356 are circumferentially offset relative to the ratchet 352, for example, by half or one-third of the pitch length of adjacent teeth 354, to increase the number of times the pawls 356 engage with the multiple teeth 354. In some embodiments, the multiple pawls 356 are movably coupled to the ratchet body 358. In some embodiments, the ratchet body 358 may be movably coupled to the wheel tray 120 such that the ratchet body 358 can move away from the ratchet 352 to disengage the pawls 356 from the teeth 354, thereby moving the ratchet mechanism 350 to a disengaged position. The ratchet mechanism 350 can control the movement of the wheel retaining arm 200 along a first direction 30 and a second direction 40 in a manner similar to that of the ratchet mechanism 300.

[0146] exist Figure 8 In the illustrated exemplary embodiment, the ratchet tool mechanism 360 may be coupled to the arm base 210. In some embodiments, the ratchet tool mechanism 360 may operate similarly to a handheld ratchet tool. The ratchet tool mechanism 360 may include a gear 362 and a flip-up pawl 364. The flip-up pawl 364 may engage the gear 362 to control rotation of the wheel retaining arm 200 relative to the wheel tray 120. In some embodiments, the flip-up pawl 364 may operate to change the orientation of the ratchet mechanism, such that the ratchet tool mechanism 360 can prevent movement of the wheel retaining arm 200 along both a first direction 30 and a second direction 40. In some embodiments, the ratchet tool mechanism 360 may be integral with the arm base 210.

[0147] In some embodiments, the axle 250 may extend through the hub 126 and be coupled to the wheel retaining arm 200, for example, as Figures 9 to 1As shown in 3B. In some embodiments, the shaft 250 may be part of the wheel retaining arm 200. In some embodiments, the shaft 250 may include a first end 252 coupled to a first arm 234 and a second end 254 coupled to a second arm 236. In some embodiments, the shaft 250 may be coupled to an arm base 210. In some embodiments, a bolt 256 extends through the first arm 234 and the second arm 236 and extends into the first end 252 and the second end 254 of the shaft 250 to couple the shaft to a pair of upright arms 234, 236. In some embodiments, the shaft 250 may extend through the hub 126 of the wheel tray 120. For example, as... Figure 9 and Figure 10 As shown, the arm base 210 may include a sleeve 224 that extends along and engages with a portion of the shaft 250. The sleeve 224 may increase the connection length between the arm base 210 and the shaft 250, allowing loads from the first arm 234 and the second arm 236 to be transmitted through the shaft 250.

[0148] Shaft 250 may be coupled to the first arm 234 and the second arm 236 and is configured to rotate together with the first arm 234 and the second arm 236. In some embodiments, shaft 250 may be configured to increase the stiffness and / or strength of the wheel retaining arm 200, such that the wheel retaining arm 200 can accommodate increased loads acting on the load-bearing frame 100 (e.g., increased weight of the bicycle 102 or increased maneuvering loads from vehicle movement). In some embodiments, shaft 250 may include a cross-sectional shape to increase the torsional stiffness of shaft 250 and to transmit loads between arms 234, 236. For example, the cross-sectional shape of shaft 250 may be hexagonal, square, or any other suitable polygonal shape. In some embodiments, shaft 250 may include, for example, protruding or recessed features extending along the length of shaft 250 to increase the torsional stiffness and strength of shaft 250, such as, for example, splines or grooves. In some embodiments, sleeve 224 may include features (e.g., shape, notch, protrusion) corresponding to shaft 250 to engage with shaft 250 and transfer load from arms 234, 236 to shaft 250.

[0149] In some embodiments, such as those shown in FIG12, the wheel retaining arm 200 may include a bracket 260 extending from the first arm 234 to the second arm 236 and connecting the first arm 234 and the second arm 236 together. The bracket may be disposed outside the hub 126. In some embodiments, the wheel retaining arm 200 may include an axle 250, a bracket 260, or both.

[0150] In some embodiments, the wheel retaining arm 200 may include a biasing mechanism 280, for example, as shown in Figures 13A and 13B. The biasing mechanism 280 may be configured to move the wheel retaining arm 200 from a first position 10 to a second position 20 without user intervention. The biasing mechanism 280 may be coupled to the axle 250 and the wheel tray 120 and disposed within the hub 126 of the wheel tray 120. The biasing mechanism 280 may include a first body 282, a second body 284, a first spring 286, and / or a second spring 288. The first body 282 may be coupled to the wheel tray 120. In some embodiments, the first body 282 may be movably coupled to the wheel tray 120 such that the first body 282 can translate relative to the wheel tray 120 along axis 128, but is rotatably fixed relative to the wheel tray 120. The second body 284 may be coupled to the axle 250 and configured to rotate together with the axle 250 and the wheel retaining arm 200. In some implementations, the second body 284 can be translated along axis 250.

[0151] In some embodiments, the first body 282 of the biasing mechanism 280 may include a first inclined end wall 290 that faces and engages a corresponding second inclined end wall 292 of the second body 284, for example, as shown in Figures 13A and 13B. A first spring 286 may bias the first body 282 toward the second body 284. A second spring 288 may bias the second body 284 toward the first body 282. In some embodiments, only one of the first body 282 and the second body 284 is configured to translate such that only one of the translated bodies 282, 284 is biased toward the other body 282, 284 by one of the springs 286, 288. In some embodiments, the biasing forces of the springs 286, 288 engage the inclined end walls 290, 292 and cause rotation of the first body 282 relative to the second body 284. The relative rotation of the first body 282 and the second body 282 may cause the wheel retaining arm 200 to rotate relative to the wheel tray 120.

[0152] In the exemplary embodiment shown in FIG13B, the wheel retaining arm 200 is in a first position 10, with the first inclined end wall 290 engaging with the second inclined end wall 292, and a circumferential gap 295 extending from the stop surface 294 of the first body 282 to the stop surface 296 of the second body 284. Springs 286, 288 bias the first and second bodies toward each other such that the reaction forces of the inclined end walls 290, 292 cause rotation of the bodies 282, 284. As the first and second bodies 284 rotate, the circumferential gap 295 between the stop surfaces 294, 296 closes. For example, as shown in FIG13A, when the wheel retaining arm 200 is in a second position 20, the stop surfaces 294, 296 engage to stop the rotation of the first and second bodies 284.

[0153] For example, such as Figure 14 As shown, the wheel retaining arm 200 may have a tapered shape from the distal end 230 to the fixed end 232. A first arm 234 and a second arm 236 may be spaced apart between the distal end 230 and the fixed end 232. In some embodiments, the first arm 234 and the second arm 236 are not parallel. In some embodiments, the first arm 234 and the second arm 236 extend at an angle relative to each other between the fixed end 232 and the distal end 230. The inner surface 231 of the first arm 234 may be spaced apart from the inner surface 233 of the second arm 236 by a first width 240 at the distal end 230. The inner surface 231 of the first arm 234 may be spaced apart from the inner surface 233 of the second arm 236 by a second width 242 at the fixed end 232. In some embodiments, the first width 240 may be smaller than the second width 242, such that the wheel retaining arm 200 narrows toward the distal end 230. In some embodiments, the first arm 234 and the second arm 236 extend linearly from the distal end 230 to the fixed end 232 without any bending in either arm. In some embodiments, the first arm 234 and the second arm 236 may be connected to a bridging member 235 at the distal end 230. In some embodiments, the bridging member 235 forms a continuous arc extending from the first arm 234 to the second arm 236. In some embodiments, the bridging member 235 forms a flat arcuate profile.

[0154] In some embodiments, the tapered shape of the wheel retaining arm 200 can provide structural benefits similar to those of bicycle wheel spokes. For example, if a load fixed by the wheel retaining arm 200 is tilted outward or subjected to force on the first arm 234 or the second arm 236, thereby generating a compressive force on the first arm 234 or the second arm 236, the resultant force on the relative arms 234, 236 will be a tension in the relative arms 234, 236, which can generally be more easily borne by the arms such as the first arm 234 and / or the second arm 236. In some embodiments, the combination of the shaft 250, the U-shaped portion 235, and the non-parallel arms 234, 236 forming the tapered shape can increase the overall strength and stiffness of the wheel retaining arm 200.

[0155] The wheel stop 400 is movably connected to the wheel retaining arm 200, for example, as Figures 14 to 1 As shown in Figure 9, the wheel stop 400 can translate along the first arm 234 and the second arm 236 to accommodate wheels 104 of different sizes (e.g., 24-inch, 27.5-inch, and 29-inch wheels). Due to the tapered shape of the wheel retaining arm 200, in some embodiments, the wheel retaining arm 200 may include a tapered insert 270 to allow the wheel stop 400 to move along a parallel sliding surface 272. The tapered insert 270 is coupled to each of the first arm 234 and the second arm 236. In some embodiments, the tapered insert 270 is coupled to each of the first arm 234 and the second arm 236 by welding, adhesive, bolts, snap-fit ​​connectors, or any other suitable connection method.

[0156] The tapered insert 270 may include an inner surface 272, a plurality of orifices 274, a plurality of protrusions 276, a first end 277 and / or a second end 278, for example, such as Figures 14 to 1As shown in Figure 6B, a sliding surface for the wheel stop 400 to translate is provided on the inner surface 272. A first end 277 of the tapered insert 270 may be positioned closer to the distal end 230 of the wheel retaining arm 200 than a second end 278. The first end 277 of the tapered insert 270 may have a first thickness less than a second thickness of the second end 278. In some embodiments, a protrusion 276 extends inward from the inner surface 272 and is configured to engage with a protrusion 405 of the wheel stop 400. In some embodiments, the protrusion 276 temporarily holds the wheel stop 400 in multiple positions when the retaining arm 430 is not assembled. In some embodiments, the protrusion 276 facilitates one-handed operation and movement of the wheel stop 400 along the wheel retaining arm 200. In some embodiments, one or more orifices 274 are formed in the tapered insert 270. In some embodiments, orifice 274 is aligned with orifice 238 formed in the first arm 234 and the second arm 236. In some embodiments, orifices 238, 274 are configured to receive retaining rod 430 to secure wheel stop 400 in a position corresponding to the wheel size of wheel 104 fixed to load carrier 100.

[0157] In Figure 16A to Figure 17 In the illustrated exemplary embodiment, the wheel stop 400 may include a retaining rod 430, a wheel receiving body 402, and / or an arm guide 404. The retaining rod 430 may extend through orifices 238, 274 in the first arm 234, through the wheel receiving body 402 of the wheel stop 400, and through orifices 238, 274 in the second arm 236 to secure the wheel stop 400 to the wheel retaining arm 200. In some embodiments, the retaining rod 430 may include a clamp 432 extending around at least a portion of the periphery of one of the first arm 234 or the second arm 236. The clamp 432 may be configured to secure the retaining rod 430 to the wheel retaining arm 200 and prevent the retaining rod 430 from disengaging from the wheel retaining arm 200. In some embodiments, the clamp 432 may be flexible, allowing it to deflect outward through the wider portion of the first arm 234 or the second arm 236, and then inward back to secure the retaining rod 430 in place. In some embodiments, the retaining rod 430 may be threaded to at least one of the first arm 234 or the second arm 236. In some embodiments, the retaining rod 430 may extend through the wheel retaining arm 200 and include fasteners on opposite sides of the wheel retaining arm 200 for engagement therewith, thereby securing the retaining rod 430 and the wheel stop 400 to the wheel retaining arm 200.

[0158] In some embodiments, one or more arm guides 404 may extend from the wheel receiving body 402, for example, as shown in Figures 16A and 16B. The arm guides 404 may extend around at least a portion of the periphery of the first arm 234 and the second arm 236. For example, as shown in Figure 16A, the guide arm 404 and the clamp 432 extend around opposite sides of the first arm 234 and partially overlap. In some embodiments, a protrusion 405 extends outward from the guide arm 404 to engage a protrusion 276 of the tapered insert, thereby temporarily holding the wheel stop 400 relative to the wheel retaining arm 200 when the retaining rod 430 is not inserted.

[0159] The wheel receiving body 402 can be shaped to receive different types of bicycle wheels 104, such as... Figures 15 to 1 As shown in Figure 9. For example, the wheel receiving body can accommodate a mountain bike wheel, a road bike wheel, a children's bike wheel, a fat bike wheel, or any other type of bicycle wheel and tire configuration. The wheel receiving body 402 can extend between the first arm 234 and the second arm 236. In the exemplary embodiments shown in Figures 16A and 16B, the wheel receiving body 402 can be a single piece having a fixed orientation relative to the wheel fixing arm 200.

[0160] In the exemplary embodiments shown in Figures 18 and 19, the wheel receiving body 402 can be movably mounted to the fixed arm 406. In some embodiments, the wheel receiving body 402 can pivot or move relative to the wheel fixed arm 200 in a generally arcuate shape. In some embodiments, a biasing member 408 can be coupled between the fixed arm 406 and the wheel receiving body 402 and is configured to bias the wheel receiving body 402 into contact with the wheel 104. In some embodiments, the biasing member 408 can be at least one of a spring, airbag, pad, damper, or any other suitable biasing or damping device. For example, as... Figure 20 As shown, spring 408 may be a torsion spring connected between wheel receiving body 402 and fixed arm 406. In some embodiments, torsion spring 408 may be connected between wheel receiving body 402 and wheel fixed arm 200 and configured to allow wheel receiving body 402 to rotate relative to wheel fixed arm 200. In some embodiments, wheel receiving body 402 is pivotable about fixed rod 430.

[0161] In some embodiments, the movable wheel receiving body 402 can facilitate the adaptation to angular slack in the wheel retaining arm 200 caused by a wider angular engagement in the ratchet mechanism 300. For example, if the wheel 104 is positioned on the load carrier 100 such that the angle of the wheel retaining arm 200 relative to the wheel tray 120 is an in-between engagement of the teeth 320, 330 of the ratchet mechanism 300, the wheel receiving body 402 can be moved to allow rotation of the wheel retaining arm 200 until the next angular engagement of the teeth 320, 330 is achieved. Alternatively, the wheel receiving body 402 can bias the wheel retaining arm 200 back to the previous engagement of the teeth 320, 330 in the ratchet mechanism 300. The movable wheel receiving body 402 can thereby reduce the angular slack between the wheel 104 and the wheel retaining arm 200 for better securing of the bicycle 102 to the load carrier 100.

[0162] In some embodiments, to operate the wheel stop 400, the user can pull the retaining rod 430 out of the orifices 238, 274 until it is disassembled. With the retaining rod 430 removed, the wheel stop 400 can be temporarily held in place relative to the wheel retaining arm 200, for example, by the protrusion 276 engaging with the protrusion 405. The user can easily overcome the engagement between the protrusions 276, 405 by pushing the wheel stop 400 to the desired position along the tapered insert 270 and the wheel retaining arm 200. At the desired position, the protrusion 405 of the wheel stop 400 engages the next set of protrusions 276 of the tapered insert 270 to temporarily hold the wheel stop 400 in the desired position. The user can reinsert the retaining rod 430 through the wheel retaining arm 200 and the wheel stop 400 to secure the wheel stop 400 in the desired position.

[0163] The load-bearing frame 100 may include a wheel tray 120, a hub 126', a wheel fixing arm 200, and a ratchet mechanism 500, for example, Figures 21 to 26 As shown. Although the ratchet mechanism 500 is in Figures 21 to 26 While shown as a standalone system, embodiments of this disclosure can be used with other devices and / or systems, such as, but not limited to, shaft 250, bracket 260, and wheel stop 400. In some embodiments, hub 126' may be substantially hollow and configured to receive at least a portion of ratchet mechanism 500. Figure 22A and Figure 22BIn the exemplary embodiment shown, the hub 126' has a generally square cross-sectional shape. In some embodiments, the hub 126' may have a cylindrical cross-sectional shape or other polygonal cross-sectional shapes. In some embodiments, the hub 126' may be coupled to the distal end 124 of the wheel tray 120. In some embodiments, the hub 126' may be part of the wheel tray 120 and disposed at the distal end 124 of the wheel tray 120. In some embodiments, the hub 126' may be integrally formed at the distal end 124 of the wheel tray 120.

[0164] In some embodiments, hub 126' may include hub mechanism housing 134, for example, Figure 22A , Figure 22B As shown in Figures 25A and 25B. In some embodiments, the hub mechanism housing 134 may be coupled to the end of the hub 126'. In some embodiments, the hub mechanism housing 134 may have a connecting portion 135 having a cross-sectional shape similar to that of the hub 126', such that torsional loads from the hub mechanism housing 134 can be transferred to the hub 126' and the wheel tray 120. In some embodiments, the connecting portion 135 and the hub 126' may have a square cross-sectional shape, for example, as shown in Figures 25A and 25B. Figure 22A and Figure 22B As shown. In some embodiments, the connecting portion 135 and the hub 126' may have any other polygonal cross-sectional shape that prevents relative rotation between the hub mechanism housing 134 and the hub 126'. In some embodiments, the hub 126' may have a circular cross-section and include a plurality of recesses formed in the ends of the hub 126', and the connecting portion 135 of the hub mechanism housing 134 may include a plurality of protrusions extending into the plurality of recesses, such that torsional loads can be transferred between the hub mechanism housing 135 and the hub 126'. The hub mechanism housing 134 may overlap with and extend into a portion of the cavity 218' of the arm base 210'. The hub mechanism housing 134 may contact the arm base 210' such that friction between the arm base 210' and the hub mechanism housing 134 slows the movement of the wheel fixing arm 200 along the first direction 30 and the second direction 40 when the wheel fixing arm 200 is moved relative to the wheel tray 120.

[0165] In some embodiments, the hub mechanism housing 134 may include a plurality of protrusions 130' and open ends 132', for example, Figure 22AAs shown. The open end 132' may face the arm base 210' and is configured to receive the first toothed ring 504 of the ratchet mechanism 500. The protrusion 130' may extend away from the hub 126' toward the open end 132' and is configured to extend through and engage with a plurality of slots 522 in the first toothed ring 504. The protrusion 130' may extend generally parallel to the axis 128, such that the first toothed ring 504 can translate along the protrusion 130' and parallel to the axis 128 via the slots 522. In some embodiments, the number of protrusions 130' in the hub mechanism housing 134 may correspond to the number of slots 522 in the first toothed ring 504. In some embodiments, the plurality of protrusions 130' may include six protrusions, for example, as shown. Figure 22A As shown. Multiple protrusions 130' and slots 522 allow the hub mechanism housing 134 to movably hold the first toothed ring 504 and prevent rotation of the first toothed ring 504 relative to the hub mechanism housing 134 and the hub 126'. In some embodiments, the multiple protrusions 130' may include fewer than six or more than six protrusions.

[0166] The wheel fixing arm 200 may include an arm base 210' at the fixing end 232 of the first arm 234 and / or the second arm 236, for example, as Figure 21 , Figure 22A , Figure 22B As shown in Figures 25A and 25B, the arm base 210' may include a base wall 211, a first side 212', and a second side 214' opposite to the first side 212', for example, as shown in Figures 25A and 25B. Figure 22A , Figure 22B As shown in Figures 25A and 25B. In some embodiments, the first side 212' may face outward away from the wheel tray 120, and the second side 214' may face the wheel tray 120. A base wall 211 may be disposed between the first side 212' and the second side 214'. The base wall 211 may include a plurality of openings 215 extending through the base wall 211. The plurality of openings 215 may be configured to receive the legs 540 of the push member 512. In some embodiments, the plurality of openings 215 may be arranged on the base wall 211 in a pattern corresponding to the legs 540 of the push member 512. In some embodiments, a lip 216' extends from the first side 212'. The lip 216' may include a radially inwardly extending wall configured to retain the cover plate 501 of the ratchet mechanism 500.

[0167] In some embodiments, the cavity 218' may be formed in the arm base 210', for example, in the second side 214', for example, as Figure 22BAs shown. In some embodiments, a portion of the ratchet mechanism 500 may be disposed in the cavity 218'. In some embodiments, a plurality of protrusions 222' extend away from the base wall 211 on the second side 214', such that the plurality of protrusions are disposed in the cavity 218'. In some embodiments, the plurality of protrusions 222' are configured to extend through a plurality of slots 532 formed in the second toothed ring 506 of the ratchet mechanism 500. In some embodiments, the plurality of slots 532 may extend generally parallel to the axis 128. In some embodiments, a portion of the arm base 210' may extend over and contact the hub mechanism housing 134 of the hub 126', such that when the wheel retaining arm 200 is moved relative to the wheel tray 120, friction between the arm base 210' and the hub mechanism housing 134 slows the movement of the wheel retaining arm 200 along the first direction 30 and the second direction 40.

[0168] The ratchet mechanism 500 can be connected to the hub mechanism housing 134 of the arm base 210' and the hub 126', for example, as Figure 22A and Figure 22B As shown. The ratchet mechanism 500 can control the rotation of the wheel retaining arm 200 relative to the wheel tray 120. For example, when the ratchet mechanism 500 is in the engaged position 50', the ratchet mechanism 500 can be configured to prevent the wheel retaining arm 200 from moving in the first direction 30 (e.g., from the first position 10 to the second position 20) and allow the wheel retaining arm 200 to move in the second direction 40 (e.g., from the second position 20 to the first position 10). In some embodiments, when the ratchet mechanism 500 is in the disengaged position 60', the ratchet mechanism 500 can allow the wheel retaining arm 200 to move freely in both the first direction 30 and the second direction 40.

[0169] The ratchet mechanism 500 may include a cover plate 501, an actuator 502, a first toothed ring 504, a second toothed ring 506, and / or a spring 508, for example, Figure 21 As shown in Figure 25B. In some embodiments, the ratchet mechanism 500 may be at least partially disposed in the hub mechanism housing 134 of the hub 126' and / or partially disposed in the cavity 218' of the arm base 210'. The actuator 502 may be configured to move the ratchet mechanism 500 from the engaged position 50' to the disengaged position 60'. For example, as Figure 21As shown in Figures 25A and 25B, a cover plate 501 may be attached to a first side 212' of the arm base 210'. The cover plate 501 may be held by a lip 216' such that the lip 216' extends radially inward and overlaps with the outer periphery 503 of the cover plate 501. In some embodiments, the cover plate 501 may be attached to the arm base 210' by fasteners, adhesives, press fits, or by a joining process such as welding. The cover plate 501 may include an aperture 505 configured to receive at least a portion of the actuator 502.

[0170] In some embodiments, the first toothed ring 504 may be movably coupled to the hub mechanism housing 134 of the hub 126' and configured to translate along axis 128 within the hub mechanism housing 134. The first toothed ring 504 may include a plurality of teeth 520, a plurality of slots 522, an actuating surface 524, and a shaft bore 526, for example, as... Figure 22A , Figure 22B As shown in Figures 24A to 25B, the plurality of teeth 520 of the first toothed ring 504 can be configured to engage the plurality of teeth 530 of the second toothed ring 506. In some embodiments, the plurality of teeth 520 may extend axially away from the first toothed ring 504, generally parallel to axis 128.

[0171] In some embodiments, the shaft aperture 526 is formed through the first toothed ring 504, for example, as Figure 22A and 22B As shown. An actuating surface 524 may extend radially between a shaft bore 526 and a plurality of teeth 520. The actuating surface 524 may provide a flat surface for the legs 540 of the actuating member 512 of the actuator 502. In some embodiments, when the actuator 502 is moved, the legs 540 contact the actuating surface 524 to move the first toothed ring 504, thereby moving the ratchet mechanism 500 from an engaged position 50' to a disengaged position 60'. The shaft bore 526 may have a diameter larger than that of the shaft 250, such that the shaft 250 can extend through the shaft bore 526 without contacting the first toothed ring 504. In some embodiments, the shaft bore 526 may have a diameter smaller than the radial spacing of the legs 540 of the actuating member 512, such that the actuating member 512 does not extend through the first toothed ring 504, and the legs 540 engage the actuating surface 524.

[0172] In some embodiments, a plurality of slots 522 may be formed through the first toothed ring 504 and configured to receive a plurality of protrusions 130' of the hub mechanism housing 134, for example, as Figure 22A and 22BAs shown. The engagement between the slot 522 and the protrusion 130' prevents rotation of the first toothed ring 504 relative to the hub 126' while allowing axial translation of the first toothed ring 504 relative to the hub 126' and the hub mechanism housing 134 along axis 128. In some embodiments, the number of slots 522 may correspond to the number of protrusions 130'. In some embodiments, the plurality of slots 522 may include six slots. In some embodiments, the plurality of slots 522 may include more or fewer than six slots. In some embodiments, the plurality of slots 522 may be arranged on the first toothed ring 504 in a pattern corresponding to the arrangement of the plurality of protrusions 130' of the hub mechanism housing 134. In some embodiments, the slots 522 may be circumferentially equidistantly spaced around the first toothed ring 504 and radially spaced from the shaft bore 526 and the plurality of teeth 520. In some embodiments, each of the plurality of slots 522 may have a cross-sectional shape corresponding to the cross-sectional shape of the plurality of protrusions 130', and may be one of an elongated arc, a circle, or any other polygonal shape.

[0173] In some embodiments, the second toothed ring 506 may be fixedly coupled to the arm base 210' and disposed in the cavity 218'. The second toothed ring 506 may include a plurality of teeth 530, a plurality of slots 532, a plurality of orifices 534, and a shaft orifice 536, for example, Figure 22A , Figure 22B As shown in Figures 24A to 25B, the plurality of teeth 530 can be configured to engage the plurality of teeth 520 of the first toothed ring 504 when the ratchet mechanism 500 is in the engaged position 50'. In some embodiments, the plurality of teeth 520, 530 are angled such that when the ratchet mechanism 500 is in the engaged position 50', as the wheel retaining arm 200 moves in the second direction 40, the teeth 520, 530 can slide past each other, but the teeth 520, 530 are locked together and prevent rotation of the wheel retaining arm 200 in the first direction 30. In some embodiments, the plurality of teeth 530 can extend axially toward the hub 126' generally parallel to the axis 128 away from the second toothed ring 506. In some embodiments, the shaft bore 536 is formed through the second toothed ring 506, for example, as shown in... Figure 22A and Figure 22B As shown. The shaft bore 526 may have a larger diameter than the shaft 250 and the push member 512, so that the shaft 250 and the push member 512 can extend freely through the shaft bore 536 without contacting the second toothed ring 506.

[0174] In some embodiments, a plurality of slots 532 may be formed through the second toothed ring 506 and configured to receive a plurality of protrusions 222' of the arm base 210', for example, as Figure 22A and Figure 22BAs shown. The engagement between the slot 532 and the protrusion 222' prevents rotation of the second toothed ring 506 relative to the arm base 210'. In some embodiments, the number of slots 532 may correspond to the number of protrusions 222'. In some embodiments, the plurality of slots 532 may include six slots. In some embodiments, the plurality of slots 532 may include more or fewer than six slots. In some embodiments, the plurality of slots 532 may be arranged on the second toothed ring 506 in a pattern corresponding to the arrangement of the plurality of protrusions 222' of the arm base 210'. In some embodiments, the slots 532 may be circumferentially equidistantly spaced around the second toothed ring 506 and radially spaced from the shaft aperture 536 and the plurality of teeth 530. In some embodiments, each of the plurality of slots 532 may have a cross-sectional shape corresponding to the cross-sectional shape of the plurality of protrusions 222', and may be an elongated arc, a circle, or any other polygonal shape.

[0175] In some embodiments, multiple orifices 534 may be formed through the second toothed ring 506, for example, as Figure 22A and 22B As shown. In some embodiments, a plurality of orifices 534 may be configured to receive fasteners for attaching the second toothed ring 506 to the arm base 210'. In some embodiments, the plurality of orifices 534 may include one, two, three, or more than three orifices. In some embodiments, the second toothed ring 506 may be securely attached to the arm base 210' by a plurality of bolts, rivets, or other similar fasteners. In some embodiments, the second toothed ring 506 may be adhesively, bonded, or joined to the arm base 210'.

[0176] In some embodiments, the plurality of teeth 520, 530 may include 60 to 250 teeth on each of the first toothed ring 504 and the second toothed ring 506. In some embodiments, the plurality of teeth 520, 530 may include 70 to 200 teeth on each of the first toothed ring 504 and the second toothed ring 506. In some embodiments, the plurality of teeth 520, 530 may include 180 teeth on each of the first toothed ring 504 and the second toothed ring 506. Increasing the number of teeth can facilitate increasing the angular engagement between the first toothed ring 504 and the second toothed ring 506, allowing the distal end 230 of the wheel retaining arm 200 to move a shorter distance between the engagement of adjacent teeth of the plurality of teeth 520, 530 at the hub 126'. In some embodiments, the number of teeth can be increased by increasing the diameter of the first toothed ring 504 and the second toothed ring 506. In some embodiments, the number of teeth can be increased by using narrower cutting teeth on the first toothed ring 504 and the second toothed ring 506, thereby reducing the pitch length of the plurality of teeth 520, 530. In some embodiments, each of the plurality of teeth 520, 530 may include a negative angle on the engagement side of each tooth. When the teeth 520, 530 contact each other as the ratchet mechanism 500 moves to the engagement position 50', the negative angle on the engagement side of the teeth 520, 530 may facilitate pulling the first toothed ring 504 and the second toothed ring 506 together.

[0177] In some embodiments, the spring 508 may be disposed between the first toothed ring 504 and the hub mechanism housing 134, for example, as Figure 22A and Figure 22B As shown. In some embodiments, spring 508 may be configured to bias ratchet mechanism 500 into engagement position 50'. In some embodiments, spring 508 may be configured to bias first toothed ring 504 toward and engage with second toothed ring 506.

[0178] Actuator 502 may include actuator button 510, push member 512, and spring 514, for example, Figure 22A As shown in Figure 25B. In some embodiments, the actuator button 510 may be movably coupled to the arm base 210' on a first side 212'. The actuator button 510 may be movably held on the first side 212' of the arm base 210' by a cover plate 501. The actuator button 510 may include a lip 511, a body 515, a cavity 516, and an actuation protrusion 518 disposed in the cavity 516, for example, as shown in Figure 25B. Figure 22A , Figure 22B , Figure 23As shown in Figures 25A and 25B, the lip 511 may have a diameter larger than the orifice 505 of the cover plate 501 and overlap a portion of the cover plate 501. The lip 511 may be disposed between the base wall 211 and the cover plate 501 to retain and attach the actuator button 510 to the arm base 210'. In some embodiments, the body 515 extends through the orifice 505 of the cover plate 501 and extends outward away from the cover plate 501, allowing the user to hold and move the actuator button 510. In some embodiments, the outer surface of the body 515 may be knurled, including anti-slip tape or notches, or include other features that improve the user's grip on the actuator button 510.

[0179] The actuator button 510 can be configured to cover the actuation member 512 and rotate relative to the actuation member 512 and the arm base 210'. For example, as Figure 22A , Figure 22B , Figure 23 As shown in Figures 25A and 25B, a cavity 516 is formed in the actuator button 510 and configured to receive the body 542 of the actuating member 512. An actuating protrusion 518 is disposed within the cavity 516. In some embodiments, the actuator button 510 may include two actuating protrusions 518 circumferentially spaced apart around the cavity 516. In some embodiments, the actuator button 510 may include a single actuating protrusion 518 or more than two actuating protrusions 518. The actuating protrusions 518 are configured to engage with recesses 546, 548 on the actuating member 512 when the actuator button 510 is moved relative to the actuating member 512. In some embodiments, the actuating protrusion 518 may have a wedge shape corresponding to the wedge shape of the recesses 546, 548, and be pressed into the recesses 546, 548, causing the actuator button 510 to "click" or be pushed into a predefined orientation corresponding to the engagement position 50' and disengagement position 60' of the ratchet mechanism 500. In some embodiments, the wedge shape of the actuating protrusion 518 may be symmetrical or asymmetrical. In some embodiments, the actuating protrusion 518 may have a cylindrical, spherical, square, or other polygonal shape to engage the recesses 546, 548.

[0180] In some embodiments, the pushing member 512 can move the first toothed ring 504 away from the second toothed ring 506, thereby moving the ratchet mechanism 500 from the engaged position 50' to the disengaged position 60'. For example, as... Figure 22A , 22BAs shown in 24A and 24B, the actuating member 512 may include legs 540, a body 542, and an actuating surface 544. The legs 540 may extend axially away from the body 542, and the actuating surface 544 may be disposed on the opposite side of the body 542. In some embodiments, the actuating member 512 may include three legs 540. For example, as... Figure 22B As shown, the actuating member 512 includes legs 540 that are circumferentially spaced apart around its peripheral edge. In some embodiments, the actuating member 512 may include two or more legs 540. The legs 540 are configured to contact and press against the actuating surface 524 of the first toothed ring 504. Three or more legs 540 can facilitate providing a stable and balanced force on the actuating surface 524 without achieving any swaying effect or torque.

[0181] In some embodiments, the legs 540 are generally aligned with the outer peripheral surface 543 of the body 542 in a direction generally parallel to axis 128. The legs 540 may be spaced apart to correspond to a plurality of apertures 215 formed in the base wall 211 of the arm base 210', such that the legs 540 extend through the apertures 215. During actuation of the ratchet mechanism 500, the legs 540 can freely translate through the apertures 215 in the base wall 211. With the legs 540 positioned in the apertures 215, rotation of the push member 512 relative to the arm base 210' can be prevented. In some embodiments, the legs 540 may be circumferentially spaced with a diameter smaller than the shaft aperture 536 of the second toothed ring 506, such that the legs 540 extend through the shaft aperture 536 of the second toothed ring 506. In some embodiments, the legs 540 may be circumferentially spaced with a diameter larger than the diameter of the shaft bore 526 of the first toothed ring 504, such that the legs 540 contact the actuating surface 524 of the first toothed ring 504 without penetrating the first toothed ring 504. In some embodiments, the distal end of the legs 540 may have a small surface area, for example, approximately 1 mm. 2 With 10mm 2 Between, or in which the circumferential length of the leg 540 is approximately equal to its radial length. In some embodiments, the leg 540 may extend further in the circumferential direction than in the radial direction to form an arcuate contact area at the distal end. The orifice 215 in the base wall 211 may have a shape and size corresponding to the leg 540 to allow the leg to move freely within the orifice 215 during actuation of the ratchet mechanism 500.

[0182] In some embodiments, the actuating surface 544 engages with the actuator button 510 to convert movement of the actuator button 510 into linear movement of the actuating member 512 along axis 128, for example, as shown in Figures 25A and 25B. In some embodiments, when the actuator button 510 rotates about axis 128, the actuating member 512 translates parallel to axis 128 to move the ratchet mechanism 500 between an engaged position 50' and a disengaged position 60'. The actuating surface 544 may include a first recess 546 and a second recess 548, for example, as shown in Figures 25A and 25B. Figure 22A As shown in Figures 24A, 24B, 25A, and 25B, when the actuator button 510 is moved relative to the push member 512, the first recess 546 and the second recess 548 can receive the actuation protrusion 518 of the actuator button 510.

[0183] In some embodiments, notches 546, 548 extend radially across and intersect the actuating surface 544, for example, as shown in Figures 24A and 24B. In some embodiments, notches 546, 548 extend inward from the peripheral surface 543 by a distance less than the radius of the actuating member 512, to form discrete notches 546, 548 around the peripheral edge of the actuating surface 544. In some embodiments, the first notch 546 may be perpendicular to the second notch 548, such that the actuating protrusion 518 engages with the notches 546, 548 at 90-degree intervals. In some embodiments, the notches may be arranged in different circumferential orientations to increase or decrease the number of engagement points between the actuating protrusion 518 and the notches 546, 548.

[0184] In some embodiments, the first notch 546 may have a first depth 547, and the second notch 548 may have a second depth 549 different from the first depth 547, for example, as shown in Figures 24A and 24B. In some embodiments, the first depth 547 is greater than the second depth 549, such that when the actuating protrusion 518 is disposed in the first notch 546, the ratchet mechanism 500 is disposed in the engaged position 50' (e.g., as shown in Figure 24A), and when the actuating protrusion 518 is disposed in the second notch 548, the ratchet mechanism 500 is disposed in the disengaged position 60' (e.g., as shown in Figure 24B). In some embodiments, the first depth 547 of the first notch 546 may be between approximately 3 mm and approximately 10 mm. In some embodiments, the first depth 547 of the first notch 546 may be between approximately 4 mm and approximately 7 mm. In some embodiments, the first depth 547 of the first notch 546 may be approximately 5.5 mm. In some embodiments, the second depth 549 of the second notch 548 can be between about 1 mm and about 5 mm. In some embodiments, the second depth 549 of the second notch 548 can be between about 2 mm and about 4 mm. In some embodiments, the second depth 549 of the second notch 548 can be about 2.5 mm.

[0185] For example, as shown in Figures 24A and 24B, notches 546, 548 may have a wedge shape corresponding to the actuation protrusion 518. In some embodiments, the wedge shape of notches 546, 548 may be symmetrical or asymmetrical. For example, an asymmetrical wedge shape of notches 546, 548 and / or the actuation protrusion 518 can change the magnitude of the force required to rotate the actuator button 510 and move the actuation protrusion 518 into and out of the notches 546, 548. This may be advantageous in limiting the rotational degrees of freedom of the actuator button 510 relative to the arm base 210', for example, moving only between 0 degrees and 90 degrees or between 0 degrees and 180 degrees. In some embodiments, an asymmetrical wedge shape of notches 546, 548 and / or the actuation protrusion 518 may prompt the user to rotate the actuator button clockwise rather than counterclockwise (and vice versa), or prevent rotation in one direction and allow rotation in the opposite direction. In some embodiments, notches 546, 548 may have cylindrical, spherical, square or other polygonal shapes to engage the actuating protrusion 518.

[0186] In some embodiments, the spring 514 may be disposed between the base wall 211 (on the first side 212') and the actuating member 512, for example, as Figure 22A and Figure 22BAs shown. In some embodiments, the spring 514 may be configured to bias the actuating member 512 toward the actuator button 510. In some embodiments, the spring 514 biases the actuating member 512 such that the notches 546, 548 and the actuating surface 544 remain in contact with the actuation protrusion 518 of the actuator button 510 throughout all movement of the actuator 502. In some embodiments, the force required to rotate the actuator button 510 can be increased or decreased by increasing or decreasing the force applied to the actuating member 512 by the spring 514.

[0187] For example, as shown in Figures 24A and 25A, the ratchet mechanism 500 is in the engaged position 50' such that the first toothed ring 504 is biased toward the second toothed ring 506 by the spring 508, and the first toothed ring 504 engages the second toothed ring 506. In the engaged position 50', the actuator button 510 is moved such that the protrusion 518 is disposed in the first recess 546, and the push member 512 moves toward the actuator button 510 and away from the hub 126'. In some embodiments, the actuator button 510 can rotate about axis 128 and independently of shaft 250 and arm base 210'. When the protrusion 518 is disposed in the first recess 546, the leg 540 of the push member 512 is configured to be spaced apart from the actuating surface 524 of the first toothed ring 504, such that the first toothed ring 504 engages with the second toothed ring 506. When the wheel retaining arm 200 moves along the second direction 40, the first toothed ring 504 can be axially translated along the protrusion 130' and independently of the position of the push member 512 away from the second toothed ring 506, and the plurality of teeth 520, 530 can slide past each other. After the plurality of teeth have slid, the spring 508 can bias the first toothed ring 504 back toward the second toothed ring 506. When the wheel retaining arm 200 moves along the first direction 30, the first toothed ring 504 is biased toward the second toothed ring 506 to lock and maintain the engagement between the plurality of teeth 520, 530 to prevent rotation along the first direction 30.

[0188] For example, as shown in Figures 24B and 25B, the ratchet mechanism 500 is in the disengaged position 60', such that the push member 512 moves the first toothed ring 504 away from the second toothed ring 506 to create a gap between the plurality of teeth 520, 530. In the disengaged position 60', the actuator button 510 is moved such that the protrusion 518 is positioned in the second recess 548, and the push member 512 moves toward the hub 126' and away from the actuator button 510. In some embodiments, the actuator button 510 may be rotated about 30 degrees, 45 degrees, 90 degrees, or another angle about axis 128 to move the ratchet mechanism 500 from the engaged position 50' to the disengaged position 60', or vice versa. When the protrusion 518 is positioned in the second recess 548, the leg 540 of the push member 512 is configured to contact the actuating surface 524 of the first toothed ring 504 and push the first toothed ring 504 away from the second toothed ring 506. The spring 508 biases the first toothed ring 504 toward the second toothed ring 506, but the push member 512 and the leg 540 restrict the movement of the first toothed ring 504, maintain the gap between the teeth 520, 530, and prevent engagement of the first toothed ring 504 and the second toothed ring 506. In some embodiments, the actuator button 510 can hold the push member 512 in place, wherein the first toothed ring 504 is spaced apart from the second toothed ring 506, such that the ratchet mechanism 500 in the disengaged position 60' allows the user to freely move the wheel retaining arm 200.

[0189] In some embodiments, the ratchet mechanism 500 may include an indicator that shows the user whether the ratchet mechanism 500 is in an engaged position 50' or a disengaged position 60'. For example, the actuator button 510 may include an arm 519 extending radially away from the actuator button 510. In some embodiments, the ratchet mechanism 500 is in the engaged position 50' when the arm 519 is aligned with and substantially parallel to one of the upright arms 234, 236. In some embodiments, the ratchet mechanism 500 is in the disengaged position 60' when the arm 519 protrudes at an angle relative to one of the upright arms 234, 236 away from the arm base 210'. When the arm 519 protrudes at an angle relative to the upright arms 234, 236, the user can notice that the arm 519 protrudes outward from the arms 234, 236, thus providing the user with a visual indication that the ratchet mechanism 500 is in the disengaged position 60' and the wheel retaining arm 200 is not properly securing the wheel 104 of the bicycle 102. In some embodiments, the alignment of arm 519 relative to upright arms 234, 236 may indicate engagement positions 50', 60' opposite to the engagement positions disclosed above. In some embodiments, arm 519 may include a gripping portion for a user to hold when moving actuator button 510.

[0190] In some embodiments, the shaft 250 may extend through the hub 126' and be coupled to the wheel retaining arm 200, for example, as Figure 26 As shown. In some embodiments, shaft 250 may be coupled to arm base 210' and ratchet mechanism 500. In some embodiments, fasteners (e.g., bolts) may extend through arm base 210' and into the end of shaft 250 to couple shaft 250 to wheel retaining arm 200. In some embodiments, shaft 250 may extend through hub 126' of wheel tray 120. For example, as Figure 26 As shown, the arm bases 210, 210' may include a sleeve 224 that extends along and engages with a portion of the shaft 250. The sleeve 224 may increase the connection length between the arm bases 210, 210' and the shaft 250, allowing loads from the wheel-fixing arm 200 to be transmitted through the shaft 250.

[0191] Shaft 250 may be coupled to wheel retaining arm 200 and ratchet mechanism 500, and is configured to rotate together with a portion of wheel retaining arm 200 and ratchet mechanism 500. In some embodiments, shaft 250 may be configured to increase the stiffness and / or strength of wheel retaining arm 200, such that wheel retaining arm 200 can accommodate increased loads acting on load carrier 100 (e.g., increased weight of bicycle 102 or increased maneuvering loads from vehicle movement). In some embodiments, shaft 250 may include a cross-sectional shape that increases the torsional stiffness of shaft 250 and transmits the load between arms 234, 236 of wheel retaining arm 200. For example, the cross-sectional shape of shaft 250 may be hexagonal, square, circular, or any other suitable polygonal shape. In some embodiments, shaft 250 may include, for example, protruding or recessed features extending along the length of shaft 250 to increase the torsional stiffness and strength of shaft 250, such as, for example, splines or grooves. Figure 26 As shown, shaft 26 includes a groove 251 extending along the length of shaft 250. In some embodiments, sleeve 224 may include features (e.g., shape, notch, protrusion) corresponding to shaft 250 to engage with shaft 250 and transfer load from wheel retaining arm 200 to shaft 250.
