[0015] The following examples are for illustrative purposes and not for limiting the embodiments of the invention. Other suitable modifications and adaptations to various conditions and parameters commonly encountered in the art are also within the spirit and scope of this disclosure and will be apparent to those skilled in the art.

[0016] refer to Figures 1 to 4 This disclosure includes a hook-up adapter 10 configured to engage a vehicle hook-up receiver 20. In some embodiments, the hook-up adapter 10 includes a holder 300 coupled to the first arm 100 and configured to engage the vehicle hook-up receiver 20. In some embodiments, such as, for example Figure 4 As shown, the storage rack 300 includes a first portion 310 and a second portion 320, the first portion including a proximal end 304 and the second portion including a distal end 306. The mounting adapter 10 can be positioned, for example... Figures 1 to 2 The closed configuration shown and, for example, Figures 3 to 4 In the open configuration shown. In some embodiments, the hook adapter 10 includes a first arm 100 and a second arm 200, the second arm being pivotally coupled to the first arm 100, for example, via a rotary joint 500. In some embodiments, the second arm 200 is configured to lock with a housing 400 disposed on the first arm 100.

[0017] In some embodiments, the first arm 100 is a stationary arm, and the second arm 200 is a pivoting or swinging arm. In some embodiments, the second arm 200 is configured to pivot about a rotation axis 502 extending through the swivel joint 500. In some embodiments, the hook-up adapter 10 includes a receiver 204 configured to receive a load support, such as a bicycle frame supporting one or more bicycles. In some embodiments, the receiver 204 is disposed on the second arm 200 such that, for example, a user can swing open the second arm 200 to access the rear compartment of the vehicle when the bicycle frame is attached to the hook-up adapter 10. In some embodiments, such as... Figure 3 As shown, receiver 204 includes a first portion 208 and a second portion 240, wherein the first portion 208 is configured to lock with housing 400 in a closed configuration, for example, inside housing 400.

[0018] For example Figure 1 As shown, the X-axis 30 is parallel to the longitudinal axis of the bracket 300 and extends in the vehicle direction 60; the Y-axis 40 is parallel to the longitudinal axis of the second arm 200 in the closed configuration and extends orthogonally to the vehicle direction 60; and the Z-axis 50 extends perpendicularly to, for example, the bracket 300. As used herein, the term "front" (e.g., front view) refers to a view of, for example, the mount adapter 10 opposite to the vehicle direction 60. As used herein, the term "rear" (e.g., rear view) refers to a view of, for example, the mount adapter 10 in the vehicle direction 60. In some embodiments, such as, for example... Figures 1 to 2 As shown, the first arm 100 and the second arm 200 are parallel to the YZ plane in the closed configuration.

[0019] In some implementations, such as, for example Figure 1 As shown and discussed in detail below (e.g., relative to) Figures 5 to 6 At least a portion of the first arm 100 forms an angle 110 with the second arm 200 in a plane parallel to the YZ plane in a closed configuration. In some embodiments, as discussed in detail below (e.g., relative to...), Figures 7A to 13 The second arm 200 is configured to lock with the housing 400 in a closed configuration, and the second arm 200 is configured to disengage from the housing 400 and swing into an open configuration. In some embodiments, such as, for example Figure 3 As shown and discussed in detail below (e.g., relative to) Figures 7A to 13 The second arm 200 includes a receiver latch 210 configured to engage a key 410 disposed in the housing 400 to lock the first arm 100 and the second arm 200 in a closed configuration.

[0020] In some implementations, such as, for example Figure 4 As shown and discussed in detail below (e.g., relative to) Figures 14 to 17The mounting adapter 10 includes a bracket 322 disposed on the hosting rack 300 and configured to guide the second arm 200 into the housing 400 when transitioning from an open configuration to a closed configuration. In some embodiments, such as, for example Figure 4 As shown and discussed in detail below (e.g., relative to) Figures 13 to 16 ), receiver 204 includes an aperture 246 configured to receive a snap fastener 340 disposed on bracket 322 in a closed configuration. In some embodiments, such as, for example Figure 1 As shown and discussed in detail below (e.g., relative to) Figures 18 to 19 The bracket 322 is configured to support at least a portion of the receiver 204 in a closed configuration.

[0021] In some implementations, such as, for example Figures 1 to 4 As shown and discussed in detail below (e.g., relative to) Figures 20 to 30 The rotary joint 500 is configured to allow the second arm 200 to rotate from a closed configuration to an open configuration while mitigating vibration and unintentional rotation in the closed configuration. As discussed below, the embodiments disclosed herein mitigate vibration and movement of the hook adapter 10 during use (e.g., while driving) to improve durability and reduce noise.

[0022] In some implementations, such as, for example Figure 5 As shown, the first arm 100 and the second arm 200 form a downward angle 110 in a plane parallel to the YZ plane. The angled relationship between the first arm 100 and the second arm 200 better absorbs forces transmitted in the combination of the Y-axis 40 and Z-axis 50 compared to a design comprising arms parallel in the YZ plane. Orienting the second arm 200 perpendicular to forces having components on the Y-axis 40 and Z-axis better absorbs various forces encountered during use (e.g., driving). When, for example, the mount adapter 10 is used to transport loads (e.g., bicycle racks) on uneven surfaces (e.g., trails, rugged terrain), absorbing forces transmitted along multiple axes reduces vibration and movement of the mount adapter 10.

[0023] In some implementations, such as, for example Figure 5 As shown, the first arm 100 includes a first segment 104 having a first segment length 105, an angled segment 106 having an angled segment length 107, and an end segment 108 having an end segment length 109. In some embodiments, such as, for example Figure 5As shown, the first segment 104 and the end segment 108 are parallel to the second arm 200 in the YZ plane, and the angled segment 106 forms a downward angle 110 with the second arm 200 in the YZ plane. In some embodiments, the length of the angled segment 107 is greater than the length of the first segment 105 and the length of the end segment 109. In some embodiments, the length of the angled segment 107 is greater than the combined length of the first segment length 105 and the end segment length 109. In some embodiments, the length of the angled segment 107 is more than 25% greater than the combined length of the first segment length 105 and the end segment length 109. In some embodiments, the length of the angled segment 107 is more than 50%, more than 75%, or more than 100% (e.g., twice) greater than the combined length of the first segment length 105 and the end segment length 109. The larger angled segment length 107 reduces vibration and movement of the hook adapter 10 because a larger portion of the first arm 100 is perpendicular to a force orientation having components in, for example, the Y-axis 40 and the Z-axis 50.

[0024] In some embodiments, the first arm 100 includes a first segment 104 and an angled segment 106 (e.g., no end segment), and the angled segment 106 is positioned at an angle 110 relative to the second arm 200.

[0025] In some embodiments, the first arm 100 includes an angled segment 106 extending from and / or through the rotation axis 502 to a second end of the first arm (e.g., without a first segment or end segment), and positioned at a downward tilt angle 110 relative to the second arm 200. In some embodiments, for example, the rotation axis 502 extends through the apex of the downward tilt angle 110. As discussed above, increasing the length 107 of the angled segment mitigates vibration and movement of the hook adapter 10 by absorbing a larger amount of force applied on multiple axes. The first segment 104 and the end segment 108 may complement the angled segment 106 to, for example, facilitate convenient assembly and production without compromising the amount of force that the angled segment 106 can absorb.

[0026] Angled section 106 can absorb forces along its longitudinal axis, including a horizontal component (e.g., parallel to the Y-axis) and a vertical component (e.g., parallel to the Z-axis). For example, a force applied along the length of angled section 106 may include a horizontal component proportional to a cosine (downslope angle 110) and a vertical component proportional to a sine (downslope angle 110). A larger downslope angle 110 may increase the vertical force absorbed by angled section 106 (e.g., parallel to the Z-axis 50), and a smaller downslope angle 110 may increase the horizontal force absorbed by angled section 106 (e.g., parallel to the Y-axis 40). In some embodiments, downslope angle 110 is between 10° and 60°. In some embodiments, downslope angle 110 is between 10° and 20°, between 20° and 30°, between 30° and 40°, between 40° and 50°, or between 50° and 60°.

[0027] In some embodiments, receiver 204 is positioned directly above the storage rack 300 in a closed configuration. In some embodiments, such as... Figures 5 to 6 As shown, the first arm 100 includes a first arm length 102, and the second arm includes a second arm length 202 that is substantially the same as the first arm length 102. In some embodiments, the ratio of the second arm length 202 to the first arm length 102 is between 0.95 and 1.05. In some embodiments, such as... Figure 6 As shown, in the closed configuration, the receiver longitudinal axis 206 is coplanar with the bracket longitudinal axis 302 relative to a plane parallel to the XZ plane. Aligning the receiver longitudinal axis 206 with the bracket longitudinal axis 302 in the closed configuration supports an increased angled segment length 107 (to mitigate vibrations caused by forces on multiple axes). Aligning the receiver longitudinal axis 206 with the bracket longitudinal axis 302 in the closed configuration also reduces or eliminates a moment arm parallel to the Y-axis 40 and extending between the load (e.g., bicycle frame) and the bracket 300. This mitigates vibrations introduced by moments applied around the bracket 300, for example, by downward forces applied to the receiver 204 (e.g., bicycle frame).

[0028] In some implementations, such as, for example Figures 7A to 7E As shown, the mounting adapter 10 includes a first lock 402 and a second lock 404, which are configured to resist rotation, for example, of the second arm 200, relative to a plane parallel to the YZ plane (e.g., about the Y-axis 40 or an axis parallel to the Y-axis 40 and extending through the second arm 200, such as the longitudinal axis 201 of the second arm 200). In some embodiments, such as... Figures 7A to 7B As shown, the first lock 402 and the second lock 404 are disposed on opposite sides of the longitudinal axis 201 of the second arm. In some embodiments, such as... Figure 7CAs shown, the first lock is configured to apply a first locking force 402f and a corresponding first locking normal force 402n about the longitudinal axis 201. In some embodiments, for example, the first lock 402 is configured to apply a downward compressive first locking force 402f (e.g., on the receiver 204 coupled to the second arm 200), which prevents the second arm 200 from vertically shifting upward when, for example, a vehicle carrying the hook adapter 10 drives over a bump (e.g., a speed bump). In some embodiments, such as... Figure 7C As shown, the second lock 404 is configured to apply a second locking force 404f and a corresponding second locking normal force 404n. In some embodiments, for example, the second lock 404 is configured to apply a downward second locking force 404f (e.g., on the receiver 204 coupled to the second arm 200), which prevents the second arm 200 from vertically shifting upward when, for example, a vehicle carrying the hook adapter 10 drives over a bump (e.g., a speed bump). In some embodiments, for example, the first lock 402 is configured to generate a first torque 402m about the longitudinal axis 201 of the second arm in a first direction, and the second lock 404 is configured to generate a second torque 404m about the longitudinal axis 201 of the second arm in a second direction opposite to the first direction. In some embodiments, such as... Figure 7C As shown, when a vehicle carrying, for example, the hook-up adapter 10, drives over a bump (e.g., a speed bump), the first lock 402 is configured to generate a counterclockwise torque 402m about the longitudinal axis 201 of the second arm (e.g., as discussed with respect to FIG8A), and the second lock 404 is configured to generate a clockwise torque 404m about the longitudinal axis 201 of the second arm (e.g., as discussed with respect to FIG8A). Figure 17 (As discussed). Locks 402 and 404, located on opposite sides of the longitudinal axis 201 of the second arm, can generate opposing torques that, for example, reduce vibration and rotation of the second arm 200 when a vehicle travels over bumps (e.g., speed bumps).

[0029] Exemplary structures of the first lock 402 and / or the second lock 404 (e.g., key 410, latch 210, snap fastener 340, and collar 244) are discussed in detail below, but do not constitute an exhaustive or exclusive disclosure of the components forming the lock 402 and / or the lock 404 that generate opposing torques to mitigate rotation and vibration of the second arm 200 relative to a plane parallel to the YZ plane.

[0030] For example, such as Figure 7D As shown, in some embodiments, the mounting adapter 10 includes a first lock 402 (e.g., a pin) and a second lock 404 (e.g., a pin) disposed on opposite sides of the longitudinal axis 201 of the second arm. In some embodiments, such as... Figure 7DAs shown, the first lock 402 and the second lock 404 generate opposing torques about the longitudinal axis 201 of the second arm via clamping forces provided, for example, by a clamp 406 configured to compress a locking plate 408 that is connected to the housing 400 together with the first lock 402 and the second lock 404.

[0031] For example, such as Figure 7E As shown, in some embodiments, the mounting adapter 10 includes a first lock 402 and a second lock 404, which are positioned perpendicular (e.g., parallel to the Z-axis 50) to or parallel to the Y-axis 40 and extending through the axis of the second arm 200 or the first arm 100. In some embodiments, such as... Figure 7E As shown, the first lock 402 is located below the Y-axis 40 or an axis parallel to the Y-axis 40 and extending through the second arm 200 or the first arm 100, and the second lock 404 is located above the Y-axis or the axis of the first arm 100. In some embodiments, the first lock 402 is located below the longitudinal axis 201 of the second arm, and the second lock 404 is located above the longitudinal axis 201 of the second arm. In some embodiments, such as... Figure 7E As shown, the first lock 402 (e.g., a pin) is configured to engage the first arm 100 via a clamping force provided, for example, by a clamp 406. In some embodiments, the second lock 404 is a spring-biased pin configured to generate an opposing torque relative to the first lock 402 about or parallel to the axis of the Y-axis 40 and extending through the second arm 200 or the first arm 100.

[0032] In some embodiments, the first lock 402 and the second lock 404 are configured to provide opposing torques about axes parallel to the X-axis 30, Y-axis 40, and / or Z-axis 50. In some embodiments, for example, the first lock 402 and the second lock 404 are located on opposite sides of the longitudinal axis 302 of the support frame (e.g., parallel to the X-axis 30) and are configured to generate opposing torques about the longitudinal axis 301 of the support frame to mitigate, for example, vibration and rotation of the second arm 200.

[0033] As noted throughout this specification, the exemplary structures disclosed herein are not exhaustive. For example, in some embodiments, the first lock 402 is located at the longitudinal axis 201 of the second arm, and the second lock 404 is laterally spaced from the first lock 402. For example, in some embodiments, the hook adapter 10 includes a clamp 406 as the first lock 402 (e.g., in...). Figure 7D As shown in the diagram, it is positioned at the longitudinal axis 201 of the second arm and includes a second lock 404 laterally spaced from the clamp 406. In some embodiments, the hook adapter 10 includes two locks configured to mitigate, for example, vibration and rotation of the second arm 200 in a closed configuration.

[0034] The positions of the first lock 402 and the second lock 404 shown are exemplary and not exhaustive. In some embodiments, such as Figures 7C-7D As shown, the first lock 402 is located at a first lock lateral distance L1 from the longitudinal axis 201 of the second arm, and the second lock 404 is located at a second lock lateral distance L2 from the longitudinal axis 201 of the second arm. For example, Figure 7C The first lock 402 and the second lock 404 are shown to be positioned at a distance of 201 from the longitudinal axis of the second arm. Figure 7D The larger lateral distances L1 and L2 are shown. In some embodiments, the first lock 402 may be closer to the longitudinal axis 201 of the second arm than the second lock 404, and vice versa.

[0035] In some embodiments, receiver 204 includes receiver length L3. In some embodiments, the ratio of the first lock lateral distance L1 to receiver length L3 is between 0 and 1, and the ratio of the second lock lateral distance L2 to receiver length L3 is between 0 and 1. In some embodiments, the ratio of the first lock lateral distance L1 to receiver length L3 is between 0 and 0.5, or between 0.5 and 1. In some embodiments, the ratio of the second lock lateral distance L2 to receiver length L3 is between 0 and 0.5, or between 0.5 and 1. In some embodiments, the ratio of the first lock lateral distance L1 to receiver length L3 is between 0 and 0.25, between 0.25 and 0.5, between 0.5 and 0.75, or between 0.75 and 1. In some embodiments, the ratio of the second lock lateral distance L2 to receiver length L3 is between 0 and 0.25, between 0.25 and 0.5, between 0.5 and 0.75, or between 0.75 and 1.

[0036] For example, in some embodiments, the receiver length L3 is approximately 30 cm, the second arm longitudinal axis 201 equally divides the receiver 204, the first lock 402 is located at a first lock lateral distance L1 approximately 10 cm from the second arm longitudinal axis 201, and the second lock 404 is located at a second lock lateral distance L2 approximately 5 cm from the second arm longitudinal axis 201. In such exemplary embodiments, the ratio between the first lock lateral distance L1 and the receiver length L3 is approximately 0.33, and the ratio between the second lock lateral distance L2 and the receiver length L3 is approximately 0.16.

[0037] As discussed above, the structures discussed below (e.g., key 410, latch 210, snap fastener 340, and collar 244) are non-limiting examples of the first lock 402 and / or the second lock 404.

[0038] In some embodiments, such as those shown in Figures 8A and 8B, the hook adapter 10 includes a key 410 configured to engage with housing 400 and a latch 210 disposed on the first portion 208 of the receiver. In some embodiments, at least a portion of the latch 210 is configured to receive and / or abut at least a portion of the key 410 in a closed configuration to lock the second arm 200.

[0039] In some implementations, such as, for example Figure 9 As shown, key 410 includes jaws 414 and / or stops 415 connected by link 412. In some embodiments, link 412 forms a hinge joint 419, which is configured such that link 412 rotates upward about hinge joint 419 to release key 410 from latch 210, and rotates downward about hinge joint 419 (e.g., into latch 210) to move key 410 into latch 210. In some embodiments, such as, for example Figure 10 As shown, the first portion 208 of the receiver 204 includes a latch 210 configured to receive the key 410 within the housing 400 in a closed configuration. In some embodiments, the latch 210 includes a first sidewall 216, a second sidewall 220, and a base plate 222. In some embodiments, the latch 210 includes a first slot 218 disposed in the first sidewall 216. In some embodiments, the latch 210 includes a second slot 226 disposed on the base plate 222. In some embodiments, such as... Figure 10 As shown, the latch 210 includes a wedge 224 disposed on and / or forming part of the base plate 222, and a second slot 226 disposed on the wedge 224.

[0040] In some embodiments, such as shown in FIG. 8A, the first slot 218 is configured to receive jaws 414 of the key 410 in a closed configuration. The first slot 218 and jaws 414 resist vibrations and movement parallel to the X-axis 30 (e.g., vehicle direction 60). In some embodiments, such as shown in FIG. 8B, the second slot 226 is configured to receive a recess of the stop 415 in a closed configuration. In some embodiments, the second slot 226 is configured as a recess, recess, or other structure to receive the stop 415. Compression of the link 412 into the second slot 226 mitigates vibrations and movement parallel to the Y-axis (e.g., horizontal). In some embodiments, the first slot 218 and jaws 414 resist vibrations and movement parallel to the X-axis 30, and the link 412 and second slot 226 mitigate vibrations and movement parallel to the Y-axis 40.

[0041] In some embodiments, the first slot 218 is configured to receive the jaws 414 and resist vibrations and movements parallel to the Y-axis 40 (e.g., horizontally). For example, in some embodiments, the first slot 218 extends parallel to the Y-axis 40 (e.g., orthogonal to the first slot 218 in Figures 8A-8B), and the jaws 414 extends parallel to the X-axis 30 (e.g., orthogonal to the jaws 414 in Figures 8A-8B). In some embodiments, the first slot 218 is configured to receive the jaws 414 and resist vibrations and movements parallel to both the X-axis 30 and the Y-axis 40. For example, in some embodiments, the first slot 218 is closed around its periphery, and the jaws 414 include a protrusion extending downward into the first slot 218.

[0042] In some embodiments, the second slot 226 is configured to receive the stop 415 and resist vibrations and movements parallel to the X-axis 30. For example, in some embodiments, the second slot 226 extends parallel to the Y-axis 40 (e.g., orthogonal to the second slot 226 in Figures 8A-8B), and the link 412 includes a portion extending parallel to the X-axis 30 (e.g., orthogonal to the link 412 in Figures 8A-8B). In some embodiments, the second slot 226 is configured to receive the stop 415 and resist vibrations and movements parallel to both the X-axis 30 and the Y-axis 40. For example, in some embodiments, the second slot 226 is closed around its periphery and configured to surround the stop 415.

[0043] In some embodiments, as shown, for example, in Figures 11A and 11B, a stop 410 is coupled to an actuator 416 configured to rotate the key 410 to release it, for example, from the latch 210, so that the user can rotate the second arm 200 to an open configuration. In some embodiments, as shown, for example, in Figure 11A, the actuator 416 is displaced upward to compress the jaws 414 into the first slot 218 and / or to compress the stop 415 into the second slot 226. In some embodiments, as shown, for example, in Figure 11B, the actuator 416 is displaced downward to rotate the link 412 upward, causing, for example, the stop 415 to disengage from the second slot 226, and the user can swing the second arm 200 to an open configuration.

[0044] In some embodiments, such as those shown in Figures 11A and 11B, the actuator 416 includes a biasing member 418 configured to resist unlocking in a closed configuration by applying a force parallel to the Y-axis (e.g., horizontally) on the key 410. In some embodiments, such as those shown in Figures 11A and 11B, the actuator 416 extends from a compressed length 420 to an uncompressed length 422 in an open configuration. For example, a user can unlock the second arm 200 by pulling the actuator 416 outward and then pressing it down to release the key 410. In some embodiments, a user can unlock the second arm 200 by twisting the actuator 416. In some embodiments, a user can unlock the second arm 200 by twisting the actuator 416 and pushing it down. In some embodiments, a user can unlock the second arm 200 by twisting the actuator 416, pulling the actuator 416 outward, and then pressing it down. In some embodiments, actuator 416 is configured to unlock the second arm 200 when a user pushes and / or pulls actuator 416 upward. In some embodiments, actuator 416 is configured to lock the second arm 200 to housing 400 when a user pushes actuator 416 downward.

[0045] In some embodiments, the biasing member 418 includes stiffness sufficient to resist unintentional release of the key 410, and, for example, the user would have to apply a force sufficient to overcome the stiffness of the biasing member 418 to release the key 410 and pivot the second arm 200 to the open configuration. In some embodiments, for example, the stiffness coefficient of the biasing member 418 is between 500 N / M and 1500 N / M. In some embodiments, the stiffness coefficient of the biasing member 418 is between 500 N / M and 750 N / M, between 750 N / M and 1000 N / M, between 1000 N / M and 1250 N / M, or between 1250 N / M and 1500 N / M.

[0046] In some implementations, such as, for example Figure 11C As shown, the hook-up adapter 10 includes an actuator constraint 430 configured to abut the actuator 416 in a closed configuration to prevent, for example, unintentional pivoting (e.g., downward) of the actuator 416 from unlocking the second arm 200. In some embodiments, such as... Figure 11C As shown, the actuator constraint is a pin (e.g., a U-pin) configured to protrude from the housing 400 and abut the actuator 416 in a closed configuration. In some embodiments, the housing 400 is configured to receive at least a portion of the actuator constraint 430 (e.g., the U-pin) in a closed configuration. In some embodiments, such as... Figure 11DAs shown, at least a portion of the actuator constraint 430 is configured to extend through at least a portion of the housing 400 and at least a portion of the receiver 204 in a closed configuration. In some embodiments, such as, for example Figure 11E As shown, the resilient plate 432 is configured to abut and bias the actuator constraint 430 to prevent the actuator constraint 430 from unintentionally disengaging from the housing 400 and / or the receiver 204. In some embodiments, the resilient plate 432 is disposed inside the housing 400. In some embodiments, the resilient plate 432 is configured to be coupled to the outer surface of the housing 400.

[0047] In some embodiments, such as those shown in Figures 12A and 12B, the actuator 416 includes a handle 417 disposed parallel to the Y-axis 40. In some embodiments, the actuator 416 includes a lever or knob. Orienting the actuator 416 parallel to the Y-axis 40 reduces interference between the actuator 416 and, for example, the rear compartment of a vehicle, allowing the user to enter the rear compartment when the hook-up adapter 10 is attached to the vehicle hook-up receiver 20.

[0048] In some implementations, such as, for example Figure 13 As shown, actuator 416 is positioned parallel to the X-axis 30 and extends away from the vehicle direction 60. Orienting actuator 416 parallel to the X-axis 30 and extending away from the vehicle direction 60 provides access to actuator 416 without reaching, for example, the area around the bicycle frame attached to receiver 204. In some embodiments, actuator 416 is configured to unlock second arm 200 when a user pushes and / or pulls actuator 416 upward. In some embodiments, actuator 416 is configured to lock second arm 200 to housing 400 when a user pushes actuator 416 downward. In some embodiments, such as, for example... Figure 13 The actuator 416 shown is configured to operate in a similar manner to the actuator 416 shown in Figures 12A to 12B (e.g., in some embodiments, a user can unlock the second arm 200 by pulling the actuator 416 outward, and the actuator 416 includes a biasing member 418).

[0049] In some embodiments, the hook adapter includes features (e.g., bracket 322 and wedge 224) for aligning the second arm 200 into the housing 400 when transitioning the second arm 200 from an open configuration to a closed configuration. Incorrect alignment between the receiver first portion 208 and the housing 400 may introduce unwanted forces applied by the user to lock the second arm 200 in the closed configuration, and may introduce vibration and movement of the hook adapter 10.

[0050] In some implementations, such as, for example Figures 14 to 16As shown, the bracket 322 and the first portion 208 of the receiver 204 are configured to align the receiver 204 so that it fits into the housing 400 uniformly. In some embodiments, such as, for example Figure 15 As shown, the bracket 322 includes a base 324 and a ramp 326 disposed on the base 324, coupled to or integral with the base. In some embodiments, the ramp 326 includes a ramp leading edge 328 disposed relative to the base 324 at a ramp angle 330. The ramp 326 guides the receiver first portion 208 into vertical alignment for entry into the housing 400 while mitigating the force applied by the user to move the second arm 200 into the closed configuration. This prevents the user from improperly locking the second arm 200 inside the housing 400, which could introduce stress and noise into the hook adapter 10 during use (e.g., driving). In some embodiments, the ramp angle 330 is between 10° and 60°. In some embodiments, the ramp angle 330 is between 10° and 20°, between 20° and 30°, between 30° and 40°, between 40° and 50°, or between 50° and 60°.

[0051] In some implementations, such as, for example Figure 16 As shown, the receiver first portion 208 includes a wedge 224 configured to engage a ramp 326 when the second arm 200 moves into a closed configuration. In some embodiments, the wedge 224 includes a leading edge 228 positioned relative to the base plate 222 of the latch 210 at a wedge angle of incidence 230. The wedge angle of incidence 230 may be complementary to the ramp angle 330 to guide the receiver 204 into the housing 400 smoothly (e.g., to reduce force applied by the user), thereby locking the second arm 200 in the closed configuration. In some embodiments, the wedge angle of incidence 230 is between 10° and 60°. In some embodiments, the ramp angle 330 is between 10° and 20°, between 20° and 30°, between 30° and 40°, between 40° and 50°, or between 50° and 60°. The wedge 224 and ramp 326 can consistently guide the receiver 204 into the housing 400 to lock the second arm 200 in a closed configuration and mitigate potential incorrect locking in the hook adapter 10 and the associated undesirable forces and stresses.

[0052] In some implementations, such as, for example Figure 17As shown, the hook-up adapter 10 includes a collar 244 disposed on, around, or integral with a second portion 240 of the receiver 204. In some embodiments, the collar 244 includes an aperture 246 configured to receive a latching member 340 disposed on the holder 300. In some embodiments, the latching member 340 extends from the bracket 322 opposite to the vehicle direction 60. In some embodiments, a portion of the collar 244 forming the aperture 246 is configured to abut the lower surface of the latching member 340 to resist vibrations and movement of the second arm 200 parallel to the Z-axis 50 in a closed configuration. In some embodiments, the aperture 246 and the latching member 340 may align the receiver 204 into the housing 400 to lock the second arm 200 in a closed configuration. As discussed above, guided alignment reduces the force applied by the user to lock the second arm 200 in a closed configuration and reduces stresses that may be introduced into the hook-up adapter 10 during use (e.g., driving).

[0053] In some implementations, such as, for example Figures 18 to 19 As shown, the support 322 is configured to abut at least a portion of the receiver 204 in a closed configuration. The support 322 can apply a normal force to the receiver 204 to support the second arm 200 in the closed configuration. In some embodiments, the support 322 is disposed on, coupled to, or integrally formed with the second portion of the holder 300. In some embodiments, the support 322 is disposed near the distal end 306 of the holder 300. In some embodiments, such as... Figure 18 As shown, the bracket 322 extends beyond the distal end 306 of the holder 300. Positioning the bracket 322 closer to the load (e.g., bicycle frame) than the vehicle hook-up receiver 20 reduces bending stress in the hook-up adapter 10 (including the holder 300 in a closed configuration). The bracket 322, positioned near the load (e.g., bicycle frame), mitigates stresses (e.g., bending stresses) and vibrations in the hook-up adapter 10 by reducing the cantilever length and moment arm between the load (e.g., bicycle frame) and the connection between the holder 300 and the vehicle hook-up receiver 20. In some embodiments, the bracket 322 reduces stress on the second arm 200. For example, a load (e.g., bicycle frame) positioned near the distal end 306 of the holder 300 can introduce a moment that causes the receiver 204 and the second arm 200 to rotate about an axis parallel to the Y-axis 40. The bracket 322 can apply a counter-normal force to the receiver 204 to mitigate rotation about the axis parallel to the Y-axis 40. In some implementations, as discussed above, the hook adapter 10 is configured to balance the torque around axes parallel to the X-axis 30, Y-axis 40 and / or Z-axis 50.

[0054] In some implementations, such as, for example Figures 18 to 19As shown, the housing 400 and receiver 204 are positioned at an angle 424 relative to the support frame 300 (e.g., an axis parallel to the X-axis 30) in a plane parallel to the XZ plane. The angle 424 mitigates interference between the receiver 204 and the support frame 300 in a closed configuration caused by loads (e.g., bicycle frames) applied near the distal end 306 of the support frame 300. In some embodiments, the angle 424 provides a gap between the receiver 204 and the support frame 300 (e.g., bracket 322), so that applying loads (e.g., bicycle frames) near the distal end 306 of the support frame 300 does not introduce undesirable compression between the second arm 200 and the support frame 300, which could generate stress and vibration during use. In some embodiments, the angle 424 is between 0.5° and 4.5°. In some implementations, the tilt angle 424 is between 0.5° and 1.5°, between 1.5° and 2.5°, between 2.5° and 3.5°, or between 3.5° and 4.5°.

[0055] In some embodiments, the rotary joint 500 is configured to mitigate vibration and movement of the hook adapter 10 in a closed configuration. In some embodiments, such as... Figure 20 As shown, the swivel joint 500 includes a rotation axis 502 extending through the first arm 100. The rotation axis 502 extending through the first arm 100 reduces vibration and movement of the hook-up adapter 10 because the rotation axis 502 is closer to the vehicle, and therefore there is a smaller moment arm between the vehicle and the swivel joint 500 compared to the case where the rotation axis 502 extends through the second arm 200. In some embodiments, the rotation axis 502 extends through the second arm 200. The rotation axis 502 extending through the second arm 200 reduces stress in the swivel joint 500 because the load (e.g., bicycle frame) is closer to the swivel joint 500 (e.g., less bending stress) compared to the case where the rotation axis 502 extends through the first arm 100.

[0056] In some implementations, such as, for example Figure 21As shown, the rotary joint 500 includes a first pivot plate 504 and a second pivot plate 506 disposed on opposite sides of the first arm 100 and the second arm 200. In some embodiments, the first pivot plate 504 and the second pivot plate 506 are configured to pivot about a rotation axis 502 and are fixed to the second arm 200 such that the second arm 200 is configured to pivot about a rotation axis 502 extending through the first arm 100. In some embodiments, the rotary joint 500 includes fasteners, such as bolts 512 collinear with the rotation axis 502. In some embodiments, the rotary joint 500 includes at least one bushing 508, at least one washer 510, and / or at least one nut 514, wherein the at least one bushing 508, at least one washer 510, and / or at least one nut 514 are configured to resist (e.g., by friction) vibrations in the rotary joint 500 in a closed configuration. In some embodiments, bushing 508 includes a flat surface 509 configured to resist rotation of bushing 508, thereby mitigating vibration in rotary joint 500.

[0057] The swivel joint 500 guides consistent and repetitive pivoting of the second arm 200 under load (e.g., a bicycle frame) while mitigating a decrease in durability during repeated use of the hook adapter 10. In some embodiments, such as... Figure 22 As shown, the rotary joint 500 is configured to allow the second arm 200 to pivot to an open configuration, wherein the first arm 100 and the second arm 200 form an opening angle 530 greater than or equal to 45° in a plane parallel to the XY plane. In some embodiments, the opening angle 530 is between 90° and 180°. In some embodiments, the opening angle 530 is between 90° and 145°. In some embodiments, the opening angle 530 is between 100° and 130°. In some embodiments, the opening angle 530 is between 100° and 110°, between 110° and 120°, or between 120° and 130°.

[0058] In some implementations, such as, for example Figure 23 As shown, the second arm 200 includes an end cap 252 disposed near the rotary joint 500. In some embodiments, the end cap 252 is configured to abut the first arm 100 in an open configuration (e.g., when the second arm 200 is positioned relative to the first arm 100 at an opening angle 530). In some embodiments, the end cap 252 is configured to limit the maximum pivoting of the second arm 200 to the opening angle 530 in an open configuration.

[0059] In some implementations, such as, for example Figures 24A to 24BAs shown, the mounting adapter 10 includes a locking pin 520 for rotating the joint 500. In some embodiments, the locking pin 520 is configured to extend through a first pivot plate 504 and a second pivot plate 506. In some embodiments, the first pivot plate 504 and the second pivot plate 506 include locking pin orifices 522 configured to receive the locking pin 520. In some embodiments, such as... Figure 24A As shown, when in the closed configuration, the locking pin 520 resists rotation of the second arm 200 because the locking pin 520 extends along a different axis relative to the rotation axis 502, thereby responding to the force of rotation of the second arm 200 and applying a normal force to the second arm 200 in the opposite direction. In some embodiments, such as, for example Figure 24B As shown, when in the open configuration, the locking pin 520 resists rotation of the second arm 200. For example, the locking pin 520 can resist rotation of the second arm 200 from the open configuration to the closed configuration because it extends along an axis different from the rotation axis 502, thereby responding to and applying a normal force to the second arm 200 in response to and against a force that causes rotation of the second arm 200. In some embodiments, the locking pin 520 applies a normal force to the second arm 200 through a locking pin orifice 522 via contact between the locking pin 520 and the first pivot plate 504 and the second pivot plate 506.

[0060] In some implementations, such as, for example Figures 25A to 25B As shown, the locking pin 520 is configured to extend through the first pivot plate 504 and the second pivot plate 506 in a closed configuration, and the locking pin 520 is configured to extend through the first arm 100 in an open configuration. In some embodiments, such as, for example Figure 25B As shown in Figure 25, the first pivot plate 504, the second pivot plate 506, and the first arm 100 include a locking pin aperture 522 configured to receive a locking pin 520. In some embodiments, such as... Figure 25B As shown, the locking pin 520 includes a locking pin latch 524, which is configured to secure the locking pin 520 to the rotary joint 500 (e.g., the first pivot plate 504).

[0061] In some embodiments, the locking pin latch 524 is, for example, a cable (e.g., elastic), a spring, a rod (e.g., a rigid rod), or any other structure configured to attach to the first pivot plate 504 or the second pivot plate 506 (e.g., attached to a protrusion extending from the first pivot plate 504 or the second pivot plate 506). The locking pin latch 524 can resist the pivoting of the second arm 200 in the closed configuration by a tension opposite to that from pivoting from the closed configuration to the open configuration, thereby biasing the second arm 200 into the closed configuration. Resisting the pivoting of the second arm 200 in the closed configuration can mitigate vibration and movement of the hook adapter 10 in the closed configuration.

[0062] Locking pin 524 resists pivoting of the second arm 200 in the open configuration beyond, for example, the opening angle 530. For example, if a user attempts to pivot the second arm 200 beyond the opening angle 530, locking pin 524 can resist this pivoting by applying tension that biases the second arm 200 towards the opening angle 530. In some embodiments, locking pin 524 resists pivoting of the second arm 200 toward the closed configuration. For example, in some embodiments, locking pin 524 is a rigid bar that applies a normal force to the second arm 200 that resists rotation of the second arm 200 toward the closed configuration.

[0063] In some implementations, such as, for example Figure 26 As shown, the locking pin 520 is spring-biased to be held, for example, in a locking pin orifice 522 and is disposed inside the first arm 100. The spring-biased locking pin reduces the likelihood of the locking pin 520 disengaging during use (e.g., driving). The user can remove the locking pin 520 by, for example, applying sufficient force to overcome the spring stiffness in the spring-biased locking pin 520.

[0064] In some implementations, such as, for example Figure 27 As shown, the mounting adapter 10 includes a torsion lock 540 disposed along the rotation axis 502. The torsion lock 540 can automatically (e.g., without requiring a user to remove or insert the locking pin 520) lock the second arm 200 in one or more positions, such as two or three different positions. In some embodiments, the torsion lock 540 includes a first support bar 542, a second support bar 544, and a third support bar 546, wherein the first support bar 542, the second support bar 544, and the third support bar 546 are configured to resist rotation of the second arm 200 in multiple positions. In some embodiments, such as... Figure 27 As shown, the torsion lock 540 includes a tab 548. In some embodiments, the first support bar 542, the second support bar 544, and the third support bar 546 are configured to receive the tab 548 to resist rotation of the second arm 200 at multiple locations. In some embodiments, the tab 548 is resilient such that when, for example, a user applies sufficient rotational force to the second arm 200, the tab 548 compresses toward the first arm 100. When the tab 548 is sufficiently compressed toward the first arm 100, the second arm 200 is free to rotate (e.g., not constrained by the first support bar 542, the second support bar 544, or the third support bar 546) until, for example, the first support bar 542, the second support bar 544, or the third support bar 546 receives the tab 548.

[0065] In some implementations, such as, for example Figure 27 As shown, the first support bar 542 is configured to receive the tab 548 in the closed configuration to resist rotation of the second arm 200 from the closed configuration to the open configuration. In some embodiments, such as, for example Figure 28AAs shown, the second support bar 544 is configured to receive the tab 548 in the open configuration to resist rotation of the second arm 200 beyond the first opening angle 531. In some embodiments, such as, for example Figure 28B As shown, the second support bar 544 is configured to receive tabs 548 in the open configuration to resist rotation of the second arm 200 beyond a second opening angle 532 greater than the first opening angle 531.
