Locking actuator handle

Abstract

A locking actuator handle is disclosed. An actuator assembly includes a shaft defining an axis of rotation and a handle. The handle includes a manually rotatable handle body surrounding the transmission structure, the reciprocator, and the lock assembly. The transmission structure is rotatably secured to the shaft and has one or more openings. The reciprocating member is spring-biased to engage the opening. The lock assembly is operable to switch the handle between a locked mode and an unlocked mode. In the locked mode, the handle body is rotatable independently of the shaft, and in the unlocked mode, rotation of the handle body causes rotation of the shaft.

Description

[0001] Cross-reference to related applications

[0002] This application claims the benefit of priority to U.S. Provisional Patent Application No. 63 / 649,695, filed May 20, 2024, pursuant to 35 U.S.SC §119(e), the entire contents of which are incorporated herein by reference for all purposes. background

[0003] Hook-and-mount components are a common feature of recreational equipment racks (such as bicycle racks) used in vehicles. Typically, the rack's struts or tongues are received in the vehicle's tubular hook-and-mount receiver. Some struts are designed to be secured by vertical hook-and-mount bolts. Others provide convenience and ease of use by incorporating fixing mechanisms, such as extendable boots that can frictionally engage with the inner surface of the hook-and-mount receiver.

[0004] Such a mechanism can be actuated by using a handle located at the distal end of the support and / or at the rear of the attached rack. To prevent theft and accidental detachment, the handle may include a locking feature. However, inline locking features may require the handle to be in a specific position or orientation before the lock can be engaged, for example, by turning a key. A compact, easy-to-use actuator handle is needed that allows locking and unlocking in any position. Overview

[0005] This disclosure provides systems, apparatus, and methods relating to actuator assemblies and actuator handles having a position-agnostic locking function. In some examples, the actuator assembly may include a shaft defining a rotation axis and a handle. The handle may include a manually rotatable handle body surrounding a drive mechanism, a reciprocating element (shuttle), and a locking assembly. The drive mechanism is rotatably fixed to the shaft and has one or more openings. The reciprocating element may be spring-biased to engage with the openings. The locking assembly is operable to switch the handle between a locked mode and an unlocked mode. The handle body can rotate independently of the shaft in the locked mode, while in the unlocked mode, rotation of the handle body can cause rotation of the shaft.

[0006] In some examples, a lock handle for an actuator can include an outer portion, a sleeve, a lock assembly, a shuttle, and a transmission structure. The outer portion can be manually rotated about a central axis and can be rotationally engaged with the sleeve. The lock assembly can be in an axial passage of the sleeve and the shuttle can be at least partially disposed in a radial slot of the sleeve. The lock assembly can include a protrusion extending into the radial slot and the shuttle can have a recess that accommodates the protrusion. The transmission structure can be rotationally engaged with the actuator and have a plurality of openings. Each opening can be shaped to receive an end of the shuttle and the shuttle can be biased to move radially outward from the sleeve.

[0007] In some instances, a method of using an actuator handle can include operating a lock assembly in a handle body to rotate a protrusion of the lock assembly out of contact with a shuttle and allowing a biasing element to urge the shuttle radially outward into an opening of a surrounding transmission structure. The method can also include rotating the handle body to rotate the shuttle and the transmission structure.

[0008] Features, functions, and advantages can be independently implemented or combined in yet additional examples of the disclosure, additional details of which can be seen with reference to the following description and drawings. BRIEF DESCRIPTION OF DRAWINGS

[0031] Handle - a user interface to facilitate the manual application of force. A handle can be fixed or movable, and can facilitate the application of rotational and / or linear force. The term "handle" can encompass circular structures described as knobs, elongated structures described as levers, ring-shaped structures described as pulls, and / or any effective shape. The term "handle" can be limited to the surface or structure contacted by a user's hand, or can encompass additional structures and / or mechanisms to transfer manually applied force.

[0032] The various structural components disclosed herein can be constructed of any suitable material or combination of materials, such as metal, plastic, rubber, or any other material having sufficient structural strength to withstand the loads generated during use. The materials can be selected based on their durability, flexibility, weight, and / or aesthetic qualities.

[0033] Overview

[0034] Generally, a position-independent lock actuator handle can be described as comprising 3 domains: a user domain, an actuator domain, and a connection domain. Each domain can comprise multiple parts that are fastened together, in contact, and / or otherwise engaged. All parts of the user domain can be engaged to rotate together, and similarly, all parts of the actuator domain can be engaged to rotate together.

[0035] The user domain and the actuator domain can independently rotate, unless rotationally engaged by the connection domain. One or more parts of the connection domain can move axially, laterally, and / or radially to link the user domain and the actuator domain. The parts of the connection domain can be acted upon by the lock assembly to initiate movement. The rotational engagement between the user and actuator domains can be described as an unlocked mode, and disengagement can be described as a locked mode.

[0036] The lock assembly can be a part of the user domain, the actuator domain, or the connection domain. In some examples, in the locked mode, the connection domain can rotate with the user domain. In other examples, in the locked mode, the connection domain can rotate with the actuator domain. In other examples, in the locked mode, the connection domain can not rotate.

[0037] Such an actuator handle can comprise a transmission structure comprising a pair of engageable elements: a translatable element and a rotatable element. In the locked mode, the elements of the transmission structure can be disengaged, and in the unlocked mode, the elements of the transmission structure can be engaged.

[0038] The lock assembly of the actuator handle can allow or prevent movement of the translatable element and / or move the translatable element to lock and unlock the actuator handle by causing engagement or disengagement of the transmission structure element. The lock assembly can be operated by a key, code, sensor, or any effective mechanism and can include translational and / or rotational motion in the transition between locked and unlocked states.

[0039] The rotatable element can be rotationally engaged or fixed to a rotating member of the actuation mechanism. The rotatable element can also include one or more holes, slots, openings, recesses, and / or other structures configured to receive at least a portion of the translatable element. The translatable element can be biased to translate toward the receiving structure of the rotatable element.

[0040] The actuator handle can also include an external manual handle, housing, exterior portion, and / or other manual rotation device. The actuator handle can also be described as a knob or grip and can be used with any mechanism actuated by rotation of some member. For example, the locking actuator handle can be incorporated into a hitch mount fastening mechanism for a hitch rack for a bicycle.

[0041] In some examples, the rotatable element can at least partially surround the translatable element, which can be biased to move radially outward. In some examples, the translatable element can rotate around the rotatable element and can be biased to move radially inward. The translatable element can be spring biased, magnetically attracted, and / or urged to default movement in the relevant direction by any effective biasing element or other device.

[0042] The locking actuator handle can be described as having a position independent lock. Existing locking handles can require a user to rotate the handle to a specific orientation to allow the lock cylinder to turn the lock post. The actuator handle with a position independent lock as described herein can allow locking and unlocking at any position. When locked, the handle can spin without engaging the rest of the actuation mechanism. When unlocked, as the handle is rotated, the translatable element can find one of the holes of the rotatable element. Once the translatable element is received in the hole, as the user continues to rotate the handle, the handle can engage the actuation mechanism.

[0043] The locking actuator handle as described herein can also have a minimum diameter requirement. That is, the diameter of the handle can be less than existing handles. This smaller diameter can allow for greater torque output from the user for faster or more effective actuation.

[0044] Examples, components, and alternatives

[0045] The following subsections describe selected aspects of example lock actuator handles and related systems and / or methods. The examples in these subsections are intended to be illustrative and should not be construed as limiting the overall scope of the disclosure. Each subsection can include one or more distinct examples, and / or contextual or related information, functionality, and / or structure.

[0046] A. Illustrative Stanchion Knob

[0047] As Figures 1-13 shown, this subsection describes an example hitch mount 100 for a bicycle rack that includes an actuator assembly with a lock knob 102. As described above, the knob 102 is an example of a position-independent lock actuator handle.

[0048] The hitch mount 100 can be part of a vehicle rack, such as a bicycle carrier, to facilitate mounting the rack to a vehicle hitch. In this example, the hitch mount includes a stanchion 104 for insertion into a hitch receiver. The actuator assembly can allow a user to secure the stanchion in the hitch receiver from behind the rack at a distal end of the stanchion.

[0049] The actuator assembly can include a rotating shaft or member, a securing structure, and a handle. In this example, the assembly includes a bolt 106, a shoe 108, and a knob 102. In Figure 1 to depict the bolt 106, the stanchion 104 is shown as transparent. The bolt 106 is engaged with the knob 102 at a proximal end and with the shoe 108 at a distal end. When the knob 102 is used to tighten the bolt 106, the shoe 108 can extend to engage an inner surface of the hitch receiver.

[0050] The stanchion 104 includes a substantially rectangular tube with a side opening at a distal end for the shoe 108 and an opening at a proximal end. An end cap 126, partially housed in the hollow tube, closes the distal end. The bolt 106 extends from the knob 102 through the end cap 126 and the hollow interior of the stanchion 104 to engage the shoe 108.

[0051] The bolt 106 is an example of a rotating member of an actuation mechanism as described above. The knob 102 as described below can also be used with similar rotating members for other actuation mechanisms, including but not limited to bicycle racks or hitch mounting devices.

[0052] The knob 102 is configured to allow a user to tighten or loosen the bolt 106, thereby securing or releasing the hitch mount from a hitch receiver of a vehicle. The knob can be described as having a locked mode and an unlocked mode. In the locked mode, elements of the knob 102 can spin freely without turning the bolt 106. In the unlocked mode, rotation of the knob 102 can cause rotation of the bolt 106.

[0053] The knob 102 is described below in the frame of reference of a user of the hitch mount 100 positioned at the distal end of the post 104 facing the knob. The paired terms“proximal-distal” and“front-rear” or similar language can be used to describe components, spatial relationships, and / or directions. Proximal or front can describe aspects closer to the user, and distal or rear can describe aspects further from the user.

[0054] Figure 2 is an exploded view of the knob 102. Also shown are the bolt 106, end cap 126, fitting 105, and washer 121 of the actuator assembly. The fitting 105 can engage a recess or narrow portion of the bolt 106 to maintain proper relative positioning of the bolt 106, end cap 126, and post tube. The washer 121 can be a conformable or elastic material and / or can be configured to facilitate smooth rotation between the fitting 105 and end cap 126 and between the end cap and knob 102.

[0055] At the distal end, the bolt 106 has a threaded end 107 to engage a hitch mounting shoe. At the proximal end, the bolt has a hexagonal head 109 to engage a locking knob 102. In some examples, the knob and / or bolt can rotate on a bearing or other smooth rotation device.

[0056] The knob 102 includes a lock assembly 110, a handle body with an outer handle 112 and a main housing 123, a core sleeve 114, a shuttle 116, a spring 118, a drive crown 120, a rear housing 122, and a screw 124. The bolt 106 extends through a central bore of the rear housing 122 with the head 109 proximal to the rear housing. The main housing 123 includes a proximal opening 113 to expose a face 115 of the lock assembly 110. The face of the lock assembly can accept a key for locking and unlocking the knob 102.

[0057] The lock assembly, handle body, core sleeve, drive crown, and rear housing are all aligned and centered with a shared axis of rotation defined by the bolt 106. The axis of rotation can also be referred to as a longitudinal axis of the bolt. Elements of the knob 102 can be described as internal or external, inward or outward, relative to the axis of rotation of the bolt.

[0058] As shown in Figures 3-4 The rear housing 122 is secured to the main housing 123 by the screw 124 to form an enclosed space around the core sleeve 114, shuttle 116, spring 118, and drive crown 120. The housings 122, 123 can also be referred to as an outer shell and / or in combination with the outer handle 112 as an outer shell, handle body, handle portion, or outer portion of the knob 102.

[0059] The rear housing 122 is closed against the end cap 126, and the square flange 127 of the end cap can make the screws 124 inaccessible when the hanger mount is assembled, preventing access to the interior of the knob 102 by removing the rear housing.

[0060] The drive crown 120 is molded over the hexagonal head of the bolt 106, thereby rotatably fixed to the bolt. The crown can also be described as an adapter, receiver, drive wheel, or crown gear. The drive crown 120 includes a plurality of axial protrusions around a central flat face 164, which can be referred to as teeth 132. The core sleeve 114 is partially housed between the teeth 132, with the distal wall 162 of the sleeve proximate to but spaced apart from the face 164 of the crown.

[0061] The lock assembly 110 is housed in the main housing 123, but is accessible through the proximal opening 113. The front face 115 can fill the opening 113, preventing access to the interior of the knob 102 through the opening. The lock assembly extends from the opening 113 through the core sleeve 114 to interact with the reciprocating member 116. The sleeve 114 is shaped to engage and house the lock assembly 110, as referenced in Figures 5-6 and described in more detail. The sleeve includes an axially extending space 135 to accommodate the protruding flip structure 111. The sleeve can be overmolded onto the lock assembly to prevent removal or disengagement and / or to facilitate the desired interlocking spatial relationship.

[0062] The elements of the knob 102 can be described as axially fixed. That is, the lock assembly 110, the core sleeve 114, the reciprocating member 116, and the crown 120 can be mounted in the housings 122, 123 such that relative motion parallel to the axis of rotation of the bolt 106 is not permitted. Rotational and radial movement depend on the mode of the knob 102.

[0063] The knob 102 can be described in terms of the 3-domains discussed above. Under this partitioning, the lock assembly 110, the outer handle 112, the main housing 123, the core sleeve 114, and the rear housing 122 can be described as forming the user domain. The reciprocating member 116 and the spring 118 can form the connection domain, and the drive crown 120 can be the actuator domain. A user can interact with the knob 102 by turning the outer handle 112 or by using a key in the lock assembly 110. For the user, “turning the knob” can include rotating the outer handle 112, the effect of which will depend on the rotational engagement of the other elements. The bolt 106 can be rotated only by engagement with the drive crown 120.

[0064] In Figure 3 the knob 102 is shown in the locked mode. In Figure 4In the diagram, the knob is shown in the unlocked mode. In both modes, the core sleeve 114 and the reciprocating member 116 are rotatably engaged with the main housing 123 and rotate as the user turns the knob 102. The main body of the locking assembly 110 is also rotatably engaged with the core sleeve 114. In the locked mode, the drive crown 120 and the bolt 106 are not rotatably engaged with the housing and do not rotate when the user turns the knob 102. In the unlocked mode, the crown and bolt are rotatably engaged with the housing and rotate when the user turns the knob.

[0065] The lock assembly 110 also includes an axially extending protrusion or pin 128. The pin 128 is independently rotatable. That is, by turning the key in the lock assembly, the pin can rotate about the central axis of the lock assembly. The pin 128 can be described as having a locked position and an unlocked position, as referenced below. Figures 11-13 To be discussed in more detail.

[0066] The reciprocating element 116 includes a hole for receiving a first end of a spring 118. A second end of the spring presses against the inner surface of the core sleeve 114. The reciprocating element 116 is biased by the spring 118 to move out of the core sleeve 114 and into one of a plurality of holes or recesses 130 between the teeth 132 of the drive crown 120. The reciprocating element can be described as having an engaged position and a disengaged position, as referenced below. Figures 11-13 To be discussed in more detail.

[0067] In the disengagement position, such as Figure 3 As shown, the outer portion 117 of the reciprocating motion member 116 is received in the recess 130 between the teeth 132 of the transmission crown 120. When the user rotates the outer handle 112, the resulting rotation of the reciprocating motion member 116 and the engagement between the reciprocating motion member and the crown teeth can cause the crown to rotate. The crown can also rotate the bolt 106.

[0068] At the joint position, such as Figure 4 As shown, the reciprocating component 116 is fully housed within the core sleeve 114. Therefore, the sleeve 114 can rotate freely without the reciprocating component contacting the crown. When the user rotates the outer handle 112, the crown 120 and bolt 106 remain stationary.

[0069] The reciprocating element 116 and the crown 120 are examples of a pair of engageable elements constituting a transmission structure. The reciprocating element may also be referred to as a translational element, a reciprocating element body, a pin, or a carriage. The reciprocating element 116 can be described as being capable of radial and / or lateral translation. More specifically, the reciprocating element can move in a plane perpendicular to the axis of rotation of the bolt 106. The central axis of the reciprocating element may intersect the axis of rotation of the bolt.

[0070] Figures 5-8is an isometric view of the knob 102 cut along four planes of the knob. In the reference frame of the drawing, elements of the knob can be referred to as being up or down, above or below. In this reference frame, up corresponds to the proximal side of the user, and down corresponds to the distal side of the user. Figure 5 cut at the uppermost plane, moving down to the lowermost plane Figure 8 .

[0071] As shown in Figure 5 , the outer grip 112 surrounds the main housing 123. The main housing is keyed into the inner surface of the grip, and can also be adhered to the outer grip. In some examples, the outer grip can be a coating on the main housing 123 or can include a portion of the main housing. In the present example, the outer grip is composed of a resilient material with a high coefficient of friction to provide a comfortable and effective manual grip. The outer grip is also ridged or knurled to improve the user's grip. In general, the outer grip and / or outer portion of the main housing 123 can have a shape and / or include any materials suitable for user interaction.

[0072] The core sleeve 114 includes a plurality of external flanges or splines 136 configured to rotatably engage the main housing 123. The sleeve can be described as splined engagement with the handle body. In the present example, the sleeve includes three splines. In general, the sleeve can include any number of splines and / or any features suitable for transferring rotation between the outer housing and the sleeve. In some examples, the sleeve 114 can be fastened or adhered to the main housing 123.

[0073] In the depicted example, the main housing 123 includes a central ring 148 disposed in the interior space 152 of the housing. Three spline-receiving recesses 149 are spaced around the ring. Each recess 149 of the central ring 148 receives a spline 136 of the sleeve 114. At each recess, the central ring 148 contacts and connects to the outer wall of the main housing 123. The main housing 123 is generally frustoconical, with the diameter of the interior space 152 and the outer grip 112 increasing from top to bottom, while the central ring 148 maintains a fixed diameter.

[0074] The body portion of the lock assembly 110 extends through the axial passage 134 of the sleeve 114 (see Figure 9 ). In Figure 5 , the semi-annular flange 146 of the lock assembly is shown received in the semi-annular space 150 at the top of the passage. The passage 134 of the sleeve 114 can also be described as having an increased diameter at the top end, with a stop 151 protruding into the passage. The flange 146 has a smaller angular extent than the space 150, allowing a range of positions in the passage limited by contact between the flange 146 and the stop 151.

[0075] As shown in Figure 6As shown, the channel 134 also includes two opposing axially extending spaces 135 to accommodate the protruding flip-over structure 111 of the lock assembly 110. The flip-over structure can move between the spaces 135 when the lock assembly 110 is operated by a key, but can be accommodated by the sleeve 114 in the locked and unlocked positions.

[0076] Generally, the core sleeve 114 can be configured to conform to and accommodate any lock assembly of the rotary knob 102. The sleeve can include any spaces, channels, openings, detents, or protrusions that are suitable to allow operation of the lock assembly while rotationally engaging the lock assembly to transmit rotation of the main housing 123 to the lock assembly.

[0077] In Figure 6 the bottom end of the center ring 148 can be seen, which is vertically spaced from the teeth 132 of the drive crown 120. Where the center ring is connected to the outer wall of the main housing 123, the inner spline 153 continues to extend along the outer wall of the main housing. Three circular ribs 154 also extend from the outer wall of the main housing 123. As Figure 7 and Figure 8 shown, the circular ribs 154 each define a screw hole 155 to engage one of the screws 124.

[0078] As Figure 7 shown, in the view of Figures 5-8 the rotary knob 102 is in the unlocked mode. The shuttle 116 is in the engaged position, with the outer portion 117 extending between two teeth 132 of the drive crown 120.

[0079] In the present example, the drive crown 120 includes five teeth 132 and five recesses 130. The teeth and recesses have approximately equal angular extent, but have different shapes, as discussed further with reference to Figure 11 below. The sleeve 114 fits closely in the center of all five teeth, but is spaced from the crown 120. When the rotary knob 102 is in the locked mode, the sleeve can not contact the crown to facilitate easy relative rotation.

[0080] Generally, the crown can have any number of teeth of any size. Preferably, the crown can include at least three recesses suitable to receive the shuttle 116. The more the number of recesses, the less the angular distance between the recesses, and the less the rotational travel required to align the shuttle with the nearest recess.

[0081] In Figure 8 the rear housing 122 and the head 109 of the bolt 106 can be seen. The drive crown 120 includes a hexagonal cavity that closely conforms to the bolt head, thereby rotationally fixing the crown to the bolt.

[0082] The rear housing includes a plurality of linear bosses 156 extending upward between the splines 153 and ribs 154 of the main housing 123. The bosses can also be referred to as vertical protrusions or surface features on the upper or proximal surface 158 of the rear housing 122 and can align the screw holes in the rear housing with the holes 155 to allow for installation of the screws 124. In addition to the screws 124, the bosses can also rotationally engage the rear housing with the main housing.

[0083] The drive crown 120 is spaced apart from all of the elements of the main housing 123 and the rear housing 122, including the splines 153, the ribs 154, and the bosses 156. Figure 8 As shown, the crown is also spaced apart from the proximal surface 158 of the rear housing. The lack of contact between the crown and the housing due to this spacing can allow the housing to freely rotate relative to the crown when the knob is in the locked mode. Figures 3-4

[0084] The core sleeve 114 can be seen in greater detail in Figure 9 The sleeve is generally cylindrical with an open proximal end and a closed distal end. The proximal end opens into an axial channel 134 configured to receive the lock assembly 110, as discussed above with reference to Figures 5-6 The core sleeve 114 includes a transverse or radial extending slot 138 at the closed proximal end. That is, the sleeve includes an opening into a substantially linear hole that can be referred to as a transverse slot or radial slot.

[0085] The slot 138 opens into the axial channel 134. The slot can be described as being closed at one end, or not extending completely through the core sleeve 114. At the closed end of the slot 138, the sleeve includes a circular recess 137 to seat and / or retain the spring 118 in place. The slot 138 is shaped to closely fit the reciprocating member 116 without impeding the reciprocating member from sliding in and out of the slot.

[0086] The core sleeve 114 can be described as having a proximal or upper half 168 and a distal or lower half 170. The upper half is generally cylindrical, includes the external splines 136 and is configured to engage the lock assembly 110. The lower half has a side opening 139 into the slot 138 and the lowermost portion of the channel 134 and is configured to engage the reciprocating member 116. In the present example, the upper half 168 and the lower half 170 have equal outer diameters, with the splines 136 tapering down to the lower half.

[0087] ​In the present example, the slot 138 can be described as T-shaped and / or having an upper portion defined between opposing protruding walls 141. The walls 141 can be linear, extending across the passage 134 and perpendicular to the axis of rotation of the knob 102 without intersecting the axis. That is, the extent of the walls can be described as lateral rather than radial. One of the walls 141 includes a notch 160 on the upper side. The walls can also be described as L-shaped or cutouts. Below the walls 141, a lower portion of the slot 138 can be wider than the upper portion between the walls.

[0088] In the present example, the shuttle 116 includes a pair of side flanges or wings 140 on laterally opposite sides, and a rectangular recess 142 on the proximal or upper surface. The recess can be described as open on the top and one side. In other words, the recess is defined or enclosed by a back wall 144 and a side wall 145 on the upper surface of the shuttle. An asymmetric protrusion 166 extends out from the back wall 144, past the recess 142.

[0089] When the shuttle 116 is received in the slot 138, the walls 144, 145 and the recess 142 can be disposed in the upper portion of the slot, while the wings 140 can be disposed in the lower portion of the slot. The asymmetric protrusion 166 can be accommodated in the notch 160. The walls 141 of the slot can limit axial movement of the wings 140. In the present example, the wings 140 extend only partially along the shuttle to avoid interference with the drive crown. The wings can be described as swept back or angled to complement the inside of the crown teeth.

[0090] The wings 140 and the protrusion 166 can stabilize and position the shuttle 116 in the slot 138. The shuttle 116 is biased by a spring to move radially out of the slot 138, but can remain at least partially accommodated in the slot at all times. Thus, the shuttle can rotate with the core sleeve 114, and can transmit rotation of the core sleeve to the drive crown in the engaged position.

[0091] The rectangular recess 142 is configured to receive and engage the pin 128 of the lock assembly 110. The pin extends downward through the passage 134, into the slot 138 and the recess 142. Contact between the pin 128 and the shuttle 116 can transition the shuttle to the disengaged position and maintain the shuttle in the disengaged position, as described further with reference to Figures 11-13

[0092] In the present example, operation of the lock assembly 110 causes the pin 128 to rotate about the body of the assembly. Generally, the movement of the pin 128 can be based on the characteristics of the lock assembly 110. The pin 128 can undergo various types of movement, including but not limited to translational or radial movement, so long as the line between the locked and unlocked positions rotates with the sleeve 114 and the shuttle 116. That is, so long as the movement of the pin 128 remains aligned with the orientation of the shuttle 116.​

[0093] In the present example, the outer portion 117 of the shuttle 116 has a generally rectangular shape, with a rounded lower surface and generally flat side bearing surfaces 119. The edges of the outer portion are rounded to facilitate smooth engagement with the drive crown.

[0094] In general, the slot 138 can be shaped to conform to the shuttle 116, and the shuttle can have any shape suitable to facilitate translation in response to movement of the pin 128 and to transmit rotational motion to the drive crown.

[0095] Figure 10 is a side view of the lock assembly 110, the core sleeve 114, the shuttle 116, and the drive crown 120 as assembled in the knob 102. The crown can be described as surrounding the core sleeve 114 and the lower half of the shuttle 116, and / or including an axially extending circumferential flange surrounding the sleeve and shuttle. The shuttle 116 is shown engaged with the recess 130 of the drive crown 120. The outer portion 117 of the shuttle 116 is shaped to closely correspond to the recess 130 of the crown, which are substantially identical to one another in shape and size. Each tooth 132 has a height 172 and is spaced from the next tooth by a distance 174. The top surface of each tooth is substantially flat, and the bottom surface 176 of each recess is substantially curved.

[0096] Each tooth has two side surfaces 131, which are configured to engage the bearing surfaces 119 of the shuttle 116. In the present example, the side surfaces 131 and the bearing surfaces 119 are each generally flat. In some examples, the surfaces can have some complementary shape. As the shuttle 116 is rotated by the sleeve 115, one of the bearing surfaces 119 can contact an adjacent one of the side surfaces 131. Rotational motion can be transmitted to the drive crown by this contact.

[0097] The surfaces 131, 119 can be described as extending laterally. That is, the plane defined by each surface can not intersect the rotational axis of the knob. As can be seen in Figure 11 As can be seen in, the planes of the side surfaces 131 of the teeth 132 do not all intersect at a central point of the drive crown 120. More specifically, the proximal side surfaces of any two adjacent teeth are parallel to one another. As a result, the recesses 130 each have a constant width, allowing the passage of the shuttle 116.

[0098] Figures 11-13 is a detail view of the drive crown 120, the core sleeve 114, the shuttle 116, the spring 118, and the pin 128 of the lock assembly 110, with the remainder of the lock assembly cut away for clarity. Figure 11 the lock mode of the knob 102 is shown, Figure 12The first stage of the knob's unlocking mode is shown, and Figure 13 The second stage of the unlock mode is shown.

[0099] like Figure 2 and Figures 11 to 13 As shown and as described above, the drive crown 120 includes recesses 130 defined between the protrusions 132. The crown can also be described as a crown gear with teeth 132, a circumferential flange with recesses or holes 130, and / or a body having a plurality of axially extending protrusions 132 spaced apart around a proximal edge. In this example, the drive crown 120 includes five recesses 130. The crown may additionally or alternatively have any shape and / or include any features suitable for receiving and engaging the reciprocating motion element 116.

[0100] exist Figure 11 In the middle position, knob 102 is locked. Pin 128 of the locking assembly is in the locked position, contacting the rear wall 144 of the recess 142 of the reciprocating member 116. The reciprocating member is thus held in the slot 138 of the core sleeve 114 against the bias of the spring 118. When the core sleeve 114 is rotated by the user rotating the outer housing, the reciprocating member 116 can be rotated to align with or misalign with the recess 130. However, knob 102 can be unlocked in any position, including... Figure 11 The misaligned position is shown. That is, the user can turn the key to unlock component 110 and rotate pin 128, regardless of the position of the reciprocating component 116.

[0101] When the user unlocks the lock component, pin 128, as shown Figure 11 Rotate to the direction indicated by the arrow in the image. Figure 12 The unlocked position is shown. As a result, the reciprocating member 116 no longer resists the force of the spring 118 and is pushed out of the slot 138. Figure 12 As shown, the reciprocating element 116 stops abutting against the protrusion 132 of the transmission crown 120, and the knob is unlocked but not engaged. When the pin 128 is in the unlocked position and the reciprocating element 116 is not engaged, the pin may not contact the reciprocating element.

[0102] When the user begins to turn knob 102 to actuate the mounting bracket, the knob enters the engaged state, such as... Figure 13 As shown. That is, turning the knob causes the core sleeve 114 and the reciprocating motion component 116 to rotate, as... Figure 12 As indicated by the arrow in the diagram. At a certain point, the reciprocating motion element will align with one of the recesses 130. Under the bias of the spring 118, the reciprocating motion element is further pushed out of the slot 138 and into the recess.

[0103] The reciprocating motion component 116 may be driven by pin 128 and / or wing 140 (see...) Figure 9) without extending outward past the drive crown 120. In some examples, each wing can contact one of the protrusions 132 adjacent the recess 130, the distal end portion of the shuttle being received in the recess 130. In the depicted example, when the pin is in the unlocked position and the shuttle is in the engaged position, the pin 128 constrains the shuttle 116 by contact with the back wall 144. In some examples, the pin 128 can not contact the shuttle 116 when in the unlocked position.

[0104] The user can continue to turn the knob and begin actuation. The shuttle 116 housed in the recess 130 engages one of the two adjacent protrusions 132, regardless of the manner in which the knob is turned. Thus, rotation of the handle body is transmitted through the drive crown to the bolt.

[0105] Because the five recesses 130 are equally spaced around the wheel 120, the shuttle 116 can need to rotate up to about 70 degrees or less than a quarter turn before engaging. Thus, the user can experience minimal lag before the actuator knob “sticks.”

[0106] The knob 102 can also be locked from any position. That is, the user can turn the key to lock the assembly 110, rotating the pin 128 regardless of the position of the shuttle 116. When the user locks the lock assembly, the pin 128 rotates back to the locked position as indicated by the arrow in Figure 13 When the pin 128 is rotated, the pin abuts the back wall 144 of the recess 142 in the shuttle 116. The pin can push the shuttle back into the slot 138 against the bias of the spring 118. The pin 128 is positioned relative to the shuttle 116 such that when the pin has returned to the locked position, the shuttle has been fully received into the slot 138 and returned to the disengaged position. The outer housing can then again be freely rotated relative to the drive crown and bolt.

[0107] B. Illustrative Methods

[0108] This subsection describes steps of an illustrative method 200 for securing a rack to a vehicle hitch receiver; see Figure 14 Aspects of the above-described actuator assemblies and / or handles can be used in the method steps described below. Where appropriate, reference is made to components and systems that can be used to perform each step. These references are illustrative and are not intended to limit the possible ways in which any particular step of the method can be performed.

[0109] Figure 14 is a flowchart illustrating the steps performed in an illustrative method and can not recite the entire process or all steps of the method. Although various steps of the method 200 are described below and illustrated in Figure 14The steps are depicted as being performed in a particular order, but these steps need not necessarily all be performed, and in some cases can be performed simultaneously or in a different order than shown.

[0110] While the method 200 is specific to a hitch-mounted rack, aspects of the operation of the locking actuator knob described in this method can be applicable to other examples that use a position-independent locking actuator knob as described above.

[0111] At step 202, the method includes attaching the rack to a vehicle. Sub-step 204 includes inserting the post into the hitch receiver. Examples of racks that can be attached to a vehicle include, but are not limited to, hitch-mounted bicycle racks. For such racks, the post can be the only connection to the vehicle. For some racks, other accessories such as straps or electrical connections can also be engaged in step 202.

[0112] Step 206 includes operating a securing mechanism, which can include sub-step 208 of turning a handle of the rack and sub-step 222 of securing the post in the hitch receiver. For example, a remotely actuated hitch-mounted device can be included in the post of a hitch-mounted rack. A handle of the device can be provided at a rear end of the post to extend or retract a friction brake element within the hitch receiver of the vehicle. At sub-step 208, a user can turn the handle so that at sub-step 222 the friction brake engages an inner surface of the hitch receiver to secure the post in the receiver.

[0113] Sub-steps 210-220 of step 208 can be optional and vary depending on the particular mechanism of the handle of the rack being used. Sub-steps 228-232 and 240-242 can similarly be optional and depend on the handle mechanism. In Figure 14 And in the following description, sub-steps are described as being applicable to a position-independent locking actuator handle as described above, and in particular a locking knob as described in example A.

[0114] Sub-step 210 includes manually rotating a knob of the handle. In this example, the handle can include a knob for manual rotation by a user and additional elements configured to allow for position-independent locking. The knob can be an exterior portion or handle of the handle, rotatable about a central axis of the handle.

[0115] Sub-step 212 includes rotating a reciprocating element with the knob. The knob can surround a reciprocating element, pin, or other element configured to move perpendicular to the central axis of the handle. That is, transverse or radial movement. The knob or other handle element can surround, constrain, or contact the reciprocating element such that rotation of the knob results in rotation of the reciprocating element.

[0116] Sub-step 214 includes allowing the spring bias to urge the reciprocating member to engage the core structure. The reciprocating member can be spring biased to engage one or more openings in the core structure. In some examples, the core structure can be a ring surrounding the transmission structure. In some examples, the reciprocating member can rotate about the core structure. In either example, sub-step 214 can include allowing the reciprocating member to translate radially toward the openings.

[0117] If the reciprocating member is not aligned with any of the openings of the core structure, sub-step 212 can continue through sub-step 214 until the reciprocating member is aligned with one of the openings. Once aligned, the spring bias can urge at least a portion of the reciprocating member into the corresponding one of the openings.

[0118] Sub-step 216 again includes rotating the reciprocating member with the knob, as in sub-step 212. However, with a portion of the reciprocating member received in an opening of the core structure, such rotation of the reciprocating member can cause rotation of the core structure, as in sub-step 218. That is, the core can be rotated by contact of the reciprocating member with the core structure.

[0119] Sub-step 220 includes causing the actuation shaft of the securing mechanism to rotate with the core. For example, the core structure can be fixed, fastened, connected, or in contact with a bolt or other actuation shaft such that rotation of the core structure causes rotation of the shaft.

[0120] At step 224, the method includes locking the securing mechanism. In particular, sub-step 226 includes operating a lock assembly with a key. For example, the key can be turned to transition the lock assembly of the handle from an unlocked configuration to a locked configuration, thereby transitioning the handle from an unlocked mode to a locked mode.

[0121] In the locked mode, the securing mechanism can not be operable via the handle. For example, the manual interface portion, handle, or knob of the handle can be free to rotate or otherwise move without acting on the actuation element of the securing mechanism.

[0122] Sub-step 228 includes moving a protrusion of the lock assembly. As part of the operation of the lock assembly, the protrusion can be rotated, translated, or otherwise moved by the key. The protrusion can be configured to act on the reciprocating member of the handle. For example, the protrusion can extend into a recess of the reciprocating member, and can be in contact or out of contact with one or more walls of the recess by the movement of sub-step 228.

[0123] Sub-step 230 includes disengaging the reciprocating member from the core having the protrusion. For example, movement of the protrusion in sub-step 228 can bring the protrusion into contact with the reciprocating member, and further movement can push the reciprocating member away from the opening of the core structure against the spring bias in which the reciprocating member has been at least partially received. That is, the protrusion can pull or push the reciprocating member out of contact with the core structure.

[0124] Sub-step 232 includes resisting the spring bias with the protrusion. For example, the protrusion can remain in contact with the reciprocating member and prevent the reciprocating member from translating radially toward the core structure and / or the opening of the core structure. In some examples, the reciprocating member can remain distanced from the central structure or from the surrounding structure.

[0125] At step 234, the method 200 includes using the rack. For example, a user can deploy or open the rack using the vehicle and transport the bicycle on the rack. The user can also attach the rack to the vehicle when not in use, with the locking securing mechanism preventing unauthorized removal of the rack from the vehicle.

[0126] When the user wishes to make an authorized removal of the rack, the method can proceed to step 236, which includes unlocking the securing mechanism. Similar to step 226, sub-step 238 includes operating the lock assembly of the handle with the key. However, in sub-step 238, the key can be turned to transition the handle from the locked mode back to the unlocked mode.

[0127] Similar to sub-step 228, sub-step 240 includes moving the protrusion of the lock assembly. As part of the operation of the lock assembly, the protrusion can be rotated, translated, or otherwise moved by the key, and can be moved in a direction opposite to sub-step 228. For example, the protrusion can be moved out of contact with the reciprocating member.

[0128] Similar to sub-step 214, sub-step 242 includes allowing the spring bias to push the reciprocating member toward the core. However, if the reciprocating member is not yet aligned with the opening of the core, the reciprocating member can contact a circumferential surface or flange of the core structure without being received into the opening or rotationally engaged with the core structure.

[0129] At step 244, the method includes operating the securing mechanism, and sub-step 246 includes turning the handle of the rack. Similar to sub-step 208, sub-step 246 can include optional sub-steps 210-220. If the reciprocating member engages the core in sub-step 242, the step can continue from sub-step 216. Otherwise, at sub-step 212, the reciprocating member can rotate on the circumferential surface or flange of the core structure until the opening is reached, such that sub-step 214 can continue.

[0130] Sub-step 248 includes releasing the strut from the hitch receiver, and can be performed by reversing the operation of the securing mechanism by turning the handle in the opposite direction. For example, the user can rotate the handle in sub-step 246 such that the friction brake moves out of contact with the hitch receiver at sub-step 248. Optional sub-steps 210-220 can be similarly performed regardless of the direction in which the handle is turned, and whether the securing mechanism is operated to secure the strut or release the strut.

[0131] Finally, step 250 includes removing the rack from the vehicle, including removing the strut from the hitch receiver at sub-step 252. The steps 202-250 can be repeated as needed for use of the rack. Optional sub-steps 210-220, 226-232, and 240-242 can also be used as part of other methods to use, lock, and unlock actuator handles for any actuation assembly.
