Patent Description:
Aspects of the present invention relate to covers for motor vehicles wheels, and more particularly to systems and methods facilitating rapid mounting of a wheel cover having optimized aerodynamics to at least a portion of a wheel, such as the hub, tire, and/or axle, without the use of tools.

Wheel covers for vehicles (e.g., heavy trucks, trailers, or the like) typically streamline and keep wheels clean from dirt, rain, or other debris. Conventionally, wheel covers are installed by removing one or more lug nuts from the studs of a hub or wheel, placing the wheel cover on the studs, and screwing the lug nuts back onto the studs. Such conventional methods necessarily involve one or more tools, increasing the complexity and duration of wheel cover installation and removal. Further, many conventional wheel covers obstruct a view of the hub of the wheel during routine inspection and maintenance, requiring the wheel cover to be completely removed. Additionally, conventional wheel covers often include aerodynamic inefficiencies and/or include a significant number of components and/or material, resulting in wasted resources due to fuel consumption, manufacturing costs, installation/removal time, and/or the like. As such, conventional wheel covers are neither cost effective nor efficient in use. It is with these issues in mind, among others, that various aspects of the present disclosure were developed.

<CIT> discusses a wheel cover system. In one implementation, an inward force exerted against a wheel cover of the wheel cover assembly in an inward direction towards the hub is received. The inward force overcomes a spring bias of a spring of the receiver and translates the wheel cover assembly in the inward direction. A first rotational force rotating the wheel cover assembly in a first direction is received. The first post guides and engages the first hook, and the second post guides and engages the second hook during rotation. A first positive feedback is generated in response to the inward force and the first rotational force. The wheel cover assembly is releaseably locked to the receiver by translating the wheel cover assembly in the outward direction using an outward force generated by the spring bias. The outward force provides a second positive feedback.

An invention to which the present application relates is set out in the appended independent claims. Implementations described and claimed herein address the foregoing issues by providing a wheel cover quick mount assembly and a method for covering a vehicle wheel according respectively to independent claims <NUM> and <NUM>.

Further, while multiple implementations are disclosed, still other implementations of the presently disclosed invention will become apparent to those skilled in the art from the following detailed description, which shows and describes illustrative implementations of the presently disclosed invention. As will be realized, the presently disclosed invention is capable of modifications in various aspects, all without departing from the scope of the presently disclosed invention as defined by the appended claims. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not limiting.

Aspects of the present invention involve systems and methods facilitating rapid mounting of a wheel cover having optimized aerodynamics to at least a portion of a wheel, such as the hub, tire, and/or axle, without the use of tools. As described herein, the presently disclosed invention provides a wheel cover system that is low cost, lightweight, durable, easily-installed, low maintenance, and provides optimized aerodynamics resulting in fuel cost savings. More particularly, the wheel cover system provides an aerodynamic shape generating an optimized miles per gallon of fuel savings for a vehicle. Further, the wheel cover system is lightweight with minimal parts and can be completely installed in a minute or less with routine inspections performable in seconds. The wheel cover system may be customized for a front wheel addressing the paddle-wheel effect of the vehicle's front wheel studs. Other advantages and features of the presently disclosed invention will be apparent from the present disclosure.

In one aspect, the wheel cover system includes a receiver comprising a spring installed onto a plurality of posts configured to receive a wheel cover. The wheel cover includes an engagement plate with hooks and grooves. To install the wheel cover, the wheel cover is aligned with the posts and spring until larger grooves are positioned near each post. An inward force is exerted onto the wheel cover to compress the spring, and the wheel cover is twisted to engage the smaller grooves around the posts. When the wheel cover is released, the spring translates the wheel cover outwards, thereby providing a positive feedback to the installer and locking the engagement plate against the caps of each post. The spring bias in combination with a change in diameters of radius cuts in the engagement plate and steps in the posts prevent the wheel cover from disengaging from the receiver by rotating clockwise or counter-clockwise. Once engaged, a cap may be removed from the wheel cover for quick routine maintenance of the wheel. To remove the wheel cover, the inward force is applied, overcoming the spring bias, and the wheel cover is rotated until disengaged from the receiver.

The wheel cover system can also include additional accessories to aid in stabilization of the posts. In one example, the stabilization assembly can include a plurality of stabilization bars. Each of the bars includes a first open end and a second open end and each end operable to receive a portion of a post. The bars are positioned between a pair of posts where a first open end of one bar contacts the same post as a second open end of another bar. The first open end and the second open end are fastened together to create an interference between the bars and the post, such that vibration experienced at the post is transferred to the bars, thereby stabilizing the post.

The wheel cover system can also include a locking mechanism which can, for example, prevent theft of the wheel cover system. The locking mechanism is installed onto an engagement plate and hidden behind a wheel cover, with a keyway accessible at the wheel cover to engage the locking mechanism. The locking mechanism includes a pair of bars coupled to a center mechanism and secured to the center mechanism by a receiver receptacle. When the locking mechanism is rotated in one orientation (e.g., counter-clockwise), the pair of bars are retracted towards the center mechanism. When the locking mechanism is rotated in a second orientation (e.g., clockwise), the pair of bars are pushed away from the center mechanism and are disposed adjacent to a top surface of a pair of posts. The pair of bars obstruct a distance between the pair of posts and the wheel cover required to push the wheel cover down for removal disassembly, thereby preventing the wheel cover from being removed from the wheel.

In another aspect, the wheel cover system includes a receiver comprising a spring installed onto a plurality of posts configured to receive a wheel cover. The wheel cover includes an engagement plate with openings of varying diameters. To install the wheel cover, the wheel cover is aligned with the posts and spring until larger openings are positioned near each post. An inward force is exerted onto the wheel cover to compress the spring, and the wheel cover is twisted to engage the smaller openings around the posts. When the wheel cover is released, the spring translates the wheel cover outwards, thereby providing a positive feedback to the installer and locking the engagement plate against the caps of each post. The spring bias in combination with a change in diameters of the openings in the engagement plate and steps in the posts prevent the wheel cover from disengaging from the receiver by rotating clockwise or counter-clockwise. Once engaged, a cap may be removed from the wheel cover for quick routine maintenance of the wheel. To remove the wheel cover, the inward force is applied, overcoming the spring bias, and the wheel cover is rotated until disengaged from the receiver.

To begin a detailed description of an example wheel cover system <NUM>, reference is made to <FIG>. In one implementation, the wheel cover system <NUM> includes a receiver <NUM> configured to receive and engage a wheel cover assembly <NUM>. Stated differently, the cover assembly <NUM> is configured to couple a wheel cover to a hub of a wheel via the receiver <NUM>. The cover assembly <NUM> may be multiple pieces coupled to each other or one integral, singular piece.

As can be understood from <FIG>, in one implementation, the receiver <NUM> is installed onto a plurality of studs <NUM> of a hub <NUM>. The receiver <NUM> includes a spring <NUM> connected to a plurality of posts <NUM>. As shown in <FIG>, each of the posts <NUM> is engaged to and extends outwardly from one of the studs <NUM>. A spacer <NUM> and a lug nut <NUM> may also be installed on each of the studs <NUM>, providing additional clearance height to each of the posts <NUM>. The spacer <NUM> and the lug nut <NUM> may be disposed proximal to the hub <NUM> from the post <NUM>. It will be appreciated that any number of posts <NUM> may be included depending on arrangement of the wheel cover assembly <NUM> and the studs <NUM>. For example, the receiver <NUM> may include four posts <NUM> arranged in two diametrically opposed pairs, as shown in <FIG>. In one implementation, a first pair of diametrically opposed posts <NUM> is circumferentially separated from a second pair of diametrically opposed posts <NUM> by two pairs of diametrically opposed uncovered studs <NUM>.

In one implementation, the spring <NUM> is mounted onto the first pair of diametrically opposed posts <NUM>, as shown in <FIG>. It will be appreciated that additional springs <NUM> and/or mounting orientations are contemplated. The spring <NUM> has a spring bias for releasably locking the wheel cover assembly <NUM> onto the posts <NUM>. More particularly, to install the wheel cover, a force is exerted against the spring, and once the force is strong enough to overcome the spring bias, the wheel cover assembly <NUM> may be rotated until engaged to the posts <NUM>. Once the posts <NUM> stop the rotation of the wheel cover assembly <NUM>, the force is desisted resulting in the spring bias of the spring <NUM> causing the wheel cover assembly <NUM> to translate in a direction opposite the application of the force and lock in place. The translation of the wheel cover assembly <NUM> generates a positive feedback in the form of a small jolt or similar tactile sensation confirming the wheel cover assembly <NUM> is secured to the receiver <NUM>.

Because the posts <NUM> are engaged to and extend from existing studs <NUM> of the hub <NUM> and the spring <NUM> does not impede visual access to the hub <NUM>, the receiver <NUM> provides generally unobstructed views of the hub <NUM>. Such an arrangement provides many advantages, including without limitation, performance of routine maintenance without removal of the receiver <NUM>; ability to mount additional components to the hub <NUM>, such as a hub meter; and the hub <NUM> can include unobstructed signage or a viewing screen showing a message, such as an advertisement, that is projected onto or otherwise visible on the wheel cover.

In one implementation, the receiver <NUM> falls within the circumference of the center of the wheel when mounted onto the hub <NUM>, allowing for removal of the tire or other portions of the wheel without the removal of the receiver <NUM>. The receiver <NUM> may also be installed onto a wheel such that the cover assembly <NUM> would cover the lug nuts. Moreover, the receiver <NUM> does not require any evidentiary mounting mechanism such as in conventional systems, allowing the cover assembly <NUM> to obtain optimized aerodynamic shape. In one implementation, the posts <NUM> are mounted to a plate to permit the use of the wheel cover system <NUM> on trailer hubs to cover the wheels. The plate would permit hubs that do not have significant mounting points, such as the studs <NUM>, to install the plate with the posts <NUM> for mounting the cover assembly <NUM>. In other implementations, the posts <NUM> are mounted onto other components. For example, the posts <NUM> can be mounted to an automatic tire inflating device, such as the Aperia Halo, or the like. The inflating device bolts onto a wheel and attaches to the air intake of the wheel to monitor and automatically inflate the tire, as needed. The device extends tire life, increases miles per gallon, and prevents blowouts due to underinflated tires.

As can be understood from <FIG>, the posts <NUM> may have a variety of shapes, sizes, and features. For example, the post <NUM> may have a short profile <NUM> or a long profile <NUM>. In one implementation, the post <NUM> includes an upper portion <NUM> and a lower portion <NUM>. The lower portion <NUM> includes a stem <NUM> having a stem surface <NUM>. The upper portion <NUM> begins with a first cap <NUM> disposed on the end of the post <NUM> having a top surface <NUM> and configured to prevent the cover assembly <NUM> from translating outwardly in a direction away from the hub <NUM>, thereby disengaging from the post <NUM>. The first cap <NUM> also has a cap bottom surface <NUM> configured to contact the cover assembly <NUM> when engaged with a plate <NUM>. A taper <NUM> guides the cover assembly <NUM> into position during installation and removal based on an applied force and the spring bias of the spring <NUM>. The post <NUM> further includes a hook step <NUM> and a neck step <NUM>. In one implementation, the hook step <NUM> has a larger circumference than the neck step <NUM>. A second <NUM> and a third <NUM> cap frame a spring step <NUM>. The spring step <NUM> is configured to receive and engaged the spring <NUM>. In one implementation, the second <NUM> and the third <NUM> caps each have an equal circumference larger than a circumference of the spring step <NUM>. The lower portion <NUM> includes a threaded opening configured to receive the stud <NUM>, enabling the post <NUM> to be rotationally advanced onto the stud <NUM>. An adhesive, such as Loctite, welding, and/or other attachment mechanisms may be used to further secure the post <NUM> to the stud <NUM>.

In one implementation, the first <NUM>, second <NUM>, and third <NUM> caps have a circumference equal to each other. However, the circumferences may differ from each other or two circumferences may be equal to each other while a third circumference is different. Additionally, the posts <NUM> may be manufactured with varying lengths to accommodate different wheel dimensions. For example, a front wheel of a semi-trailer truck may have the posts <NUM> with the short profile <NUM>, as shown in <FIG>, while a rear wheel may have the posts <NUM> with the long profile <NUM>, shown in <FIG>. The long profile <NUM> can accommodate a greater offset for rear dual-wheels. The posts <NUM> may be made of a hard material such as steel, aluminum, plastic, thermoplastic, and/or the like. In an example implementation, the posts <NUM> are manufactured from polyoxymethylene. After or while the posts <NUM> are installed onto the hub <NUM>, the spring <NUM> may be also installed.

Turning to <FIG>, in one implementation, the spring <NUM> includes a spring engagement point <NUM> where the spring <NUM> meets the cover assembly <NUM> during cover installation. The spring bias of the spring <NUM> may be configured to generate an outward force concentrated at the spring engagement point <NUM>. The spring <NUM> also includes a plurality of spring hooks <NUM>. In one example, the spring <NUM> has two hooks <NUM> in a semi-circular shape, as shown in <FIG>. The hooks <NUM> extend linearly away from each other, then bend and increase in angle until they reach the engagement point <NUM>. The combination of the semi-circular hooks <NUM> and flexibility of the spring <NUM> allow the spring hooks <NUM> to hook around and engage two posts <NUM> at the spring step <NUM> of each post <NUM>, as shown in <FIG>. However, the spring <NUM> can be mounted onto more than two posts <NUM> or onto one post <NUM> and bent outwards to provide the spring bias force to maintain the plate <NUM> in place. The receiver <NUM> may be permanently affixed or removably engaged to the hub <NUM>, with the wheel cover assembly <NUM> removably engageable to the receiver <NUM>.

For a detailed description of the wheel cover assembly <NUM>, reference is made to <FIG>. In one implementation, the cover assembly <NUM> includes an engagement plate <NUM> and a cover back <NUM>, illustrated as a ring in <FIG>. The ring is merely for illustrative purposes to demonstrate the connection of a wheel cover to the engagement plate <NUM>. The cover back <NUM> may be coupled to the plate <NUM> with screws <NUM> that extend through a plurality of openings <NUM> in the plate <NUM> and the cover back <NUM>. Although the plate <NUM> and the cover back <NUM> are shown as two separate components attached via screws <NUM>, the plate <NUM> and the cover back <NUM> can be one integrated unit or attached via other means. The cover back <NUM> can also be integrated into the wheel cover <NUM>.

The plate <NUM> may include a body with radius cuts of different diameters to engage the steps in the posts <NUM> having different diameters. In other words, the plate <NUM> positively engages the plurality of posts <NUM> by a precise mating of the radiused plate <NUM> to the radiused plurality of posts <NUM>. The plate <NUM> includes a plurality of hooks <NUM> disposed about and defined in a peripheral edge of the body. The hooks <NUM> may be oriented relative to a center hole <NUM>. In one implementation, the plate <NUM> has four hooks <NUM>; however, there can be more or less than four hooks <NUM> and the plate <NUM> can be any shape including, but not limited to, a rectangle, octagon, oval, or circle, as well as having various ornamental features. Furthermore, other wheel end elements providing quick detachment to expose the hub <NUM> and other wheel components such as, but not limited to, a hub odometer or tire inflation device can be mounted onto the plate <NUM> in addition to, or in place of, a wheel cover.

In one implementation, the hook <NUM> includes a hook surface <NUM> and a hook edge <NUM> defining a hook receiving area <NUM>. The hook receiving area <NUM> is adapted to snugly fit around the hook step <NUM> because the hook receiving area <NUM> has a radius equal to or substantially equal to a radius of the hook step <NUM>. Adjacent to the hook edge <NUM> is a neck edge <NUM> which, together defines a neck receiving area <NUM>. The neck receiving area <NUM> allows the post <NUM> to pass through at the neck step <NUM> during cover installation and prevents the plate <NUM> from rotating when the plate <NUM> is fully engaged on the post <NUM>. Adjacent to the neck edge <NUM> is a cap edge <NUM> defining a cap receiving area <NUM>. The cap receiving area <NUM> is adapted such that the first cap <NUM> can outwardly pass through the cap receiving area <NUM> at the beginning of installation because the cap receiving area <NUM> has a radius equal to or greater than the radius of the first cap <NUM>. The cap receiving area <NUM> and the hook receiving area <NUM> may be formed as a first groove and a second groove, respectively, wherein the first groove is larger than the second groove. The plate <NUM> may be positioned <NUM>" from dead center of a typical <NUM>-bolt hub assembly such that the radius from the center of the plate to engagement of the post <NUM> is <NUM>". The plate <NUM> can be made of a hard material such as, but not limited to, steel, aluminum, plastic, thermoplastic, or the like. In one implementation, the plate <NUM> is manufactured from a <NUM>" thick sheet of <NUM> stainless steel.

Referring to <FIG>, in one implementation, a plurality of spacers <NUM> are configured to maintain a distance between the cover back <NUM> and the plate <NUM>, such that when the wheel cover assembly <NUM> is installed onto the receiver <NUM> and the cover back <NUM> contacts the first caps <NUM>, the plate <NUM> drops into position for installation. Although the spacers <NUM> are shown as separate components, they may be integrated into the cover back <NUM> or the plate <NUM>. In one example implementation, shown in <FIG>, four spacers <NUM> are positioned adjacent four hooks <NUM> and posts <NUM>. The four hooks <NUM> and corresponding four posts <NUM> are positioned equidistance around a center circumference of the cover back <NUM>. The four screws <NUM> and corresponding four spacers <NUM> are positioned equidistance on the same center circumference and shifted clockwise from the hooks <NUM> to prevent interference with the posts <NUM>.

<FIG> illustrates a high level view of the wheel cover system <NUM> with a wheel cover <NUM>. The wheel cover <NUM> can be disc or domed shaped with various ornamental features and extends over the receiver <NUM> and plate <NUM>. The wheel cover <NUM> entirely covers the remainder of the wheel cover system <NUM> components, such as the receiver <NUM> and the plate <NUM>, as well as the internal components of the wheel, including the hub <NUM>. The wheel cover <NUM> may also include a thicker portion on the perimeter of the disc, which may provide more stability at the edge as well as prevent debris from entering the space behind the wheel cover <NUM>. The wheel cover <NUM> can be coupled to the plate <NUM> in a variety of ways. In one example, shown in <FIG>, the wheel cover <NUM> includes an attachment portion <NUM> and an opening where the screw <NUM> passes through and attaches the wheel cover <NUM> to the plate <NUM>. <FIG>further illustrate the cover assembly <NUM>, complete with the cover <NUM>, mounted to an example post <NUM> of the receiver <NUM>.

<FIG> illustrate an example installation of the cover assembly <NUM> onto the receiver <NUM>. In one implementation, the cover assembly <NUM> is positioned over the receiver <NUM>, such that the plate <NUM> is facing the posts <NUM>. The first groove, or cap receiving area <NUM>, is positioned over the posts <NUM> and the cover assembly <NUM> is pushed inwardly in a direction towards the hub <NUM> and rotated in a first direction, for example, clockwise. The spring bias of the spring <NUM> causes the cover assembly <NUM> to jolt outwardly providing positive feedback and locking the cover assembly <NUM> in place on the posts <NUM>. The cover assembly <NUM> is thereby preventing from rotating counter-clockwise or clockwise. The only way to remove or release the cover assembly <NUM> is the application of a force on the cover assembly <NUM> in direction inwardly towards the hub <NUM> and rotation of the cover assembly <NUM> in a second direction opposite the first direction (e.g., counterclockwise). The cover assembly <NUM> is rotated until disengaged from the posts <NUM>, and the spring bias of the spring <NUM> translates the cover assembly <NUM> in a direction outwardly from the hub <NUM>, releasing the cover assembly <NUM> from the receive <NUM>.

In one implementation, the wheel cover system <NUM> provides a positive feedback loop to notify a user of proper installation, as the user cannot see the parts during installation due to the wheel cover <NUM>. The feedback loop includes, but is not limited to, audial, tactile, visual, and/or other feedback. The audial feedback may be generated by the plate <NUM> hitting the first caps of each post <NUM>. The tactile feedback may come in the form of a jolt caused by the spring bias of the spring <NUM> translating the plate <NUM> outwards, enabling a user to feel the cover assembly <NUM> move against his hand. The visual feedback may be provided in how the wheel cover <NUM> is oriented relative to the wheel.

As shown in <FIG>, in one implementation, the cover assembly <NUM> is positioned such that the plate <NUM> is centered on the spring engagement point <NUM>, shown in <FIG>, and the cover back <NUM> is facing outwards. The cap receiving area <NUM> is aligned with the first cap <NUM>. When the cover assembly <NUM> receives the application of an inward force, for example from a user pushing on the cover assembly <NUM>, the cover assembly <NUM> compresses the spring <NUM>, and the cover assembly <NUM> moves inwardly in a direction towards the hub <NUM>, as indicated by the arrow shown in <FIG>.

Turning to <FIG>, after the cover assembly <NUM> is translated inwardly through the application of the inward force, the first caps <NUM> abuts the cover back <NUM>, preventing the cover assembly <NUM> from moving further inward. The spacers <NUM> distance the cover back <NUM> and the plate <NUM> such that the plate <NUM> is dropped into the same plane as the neck step <NUM>. The spacers <NUM> and the cover back <NUM> save time and effort as a user can simply push the cover back <NUM> until the cover back <NUM> contacts the first caps <NUM>. The cover assembly <NUM> is then rotated in the first direction (e.g., clockwise), as shown by the arrows.

As can be understood from <FIG>, while the cover assembly <NUM> is rotating as indicated by the arrow, the neck receiving area <NUM> receives and guides the neck step <NUM> into the hook receiving area <NUM>. When the neck step <NUM> is in the hook receiving area <NUM>, as shown in <FIG>, the inward force on the cover assembly <NUM> is desisted, resulting in the spring bias of the spring <NUM> exerting an outward force against the cover assembly <NUM> and translating the cover assembly <NUM> outwards, as shown by the arrow in <FIG>. In an example implementation, the outward force generated by the spring bias of the spring <NUM> is approximately 20lb/inch.

<FIG> illustrates the engagement plate <NUM> engaged to the posts <NUM>. In one implementation, the hook surface <NUM> is flush against the cap bottom surface <NUM> and the hook step <NUM> is positioned in the hook receiving area <NUM>. Because the combination of the width of the neck receiving area <NUM> being less than the diameter of the hook step <NUM> and the outward force provided by the spring bias of the spring <NUM>, the hook step <NUM> cannot rotate out of the hook receiving area <NUM>, thus preventing the plate <NUM> from rotating. In other words, the circumference of the hook receiving area <NUM> is about the same as the circumference of the hook step <NUM>, both of which are larger than the distance formed by the neck receiving area <NUM>, thus preventing the plate <NUM> from rotating. The spring <NUM> continually exerts an outward positive force against the plate <NUM>, which together with the first caps <NUM>, translationally and rotationally lock the plate <NUM>. In other words, the circumference of the engaging plate <NUM> in the secondary or locking position of the plate <NUM>, when displaced outwards with the force of the spring <NUM>, is dimensioned such that the plate <NUM> cannot rotate as it is more than half of the diameter of the stud step with which it engages. Furthermore, if the cover assembly <NUM> is secured on at least one post <NUM>, the surface <NUM> is engaging the entire post <NUM>. One post <NUM> can provide sufficient engagement area to hold the cover assembly <NUM> in position.

The various implementations described herein may have several additional features. For example, <FIG> illustrates the post <NUM> having a driver opening <NUM> extending into the first cap <NUM>. The driver opening <NUM> is configured to receive a driver tool, such as a screw driver, for example, to drive the post <NUM> into the hub <NUM>. The driver <NUM> may be shaped to be a hex, Phillips, slot, triangle, or the like. In an example implementation, the driver <NUM> is a half-inch square driver. The driver <NUM> provides an alternatives means to couple the post <NUM> to the hub and utilizes a driver instead of a wrench, for example.

Furthermore, the wheel cover <NUM> may also have additional features. <FIG> illustrates the wheel cover <NUM> having a center opening <NUM> accommodating a plurality of couplers <NUM>, shown in detail in <FIG>. The plurality of couplers <NUM> are configured to couple the wheel cover <NUM> to the plate <NUM>. In an example implementation, shown in <FIG>, the center opening <NUM> includes an indented ring <NUM> broken into four sections by the plurality of couplers <NUM>, wherein the plurality of couplers <NUM> have an opening sized for a screw thread to past through. The plurality of screws <NUM> couple the wheel cover <NUM> to the plate <NUM>. In other examples, the wheel cover <NUM> can be coupled to the plate <NUM> in other ways, including, but not limited to, using adhesion, welding, rivets, or the like. Further, the wheel cover <NUM> and the plate <NUM> can be one unitary piece.

The indented ring <NUM> may also be separated into sections by a plurality of cover cap receivers <NUM> adjacent to each plurality of couplers <NUM>. The plurality of cover cap receivers <NUM> are configured to receive a cover cap tab <NUM>, shown in <FIG>, of a cover cap <NUM>. In an example implementation, each cover cap receiver <NUM> is a slotted opening configured to receive each cover cap tab <NUM>. The cover cap receivers <NUM> and cover cap tabs <NUM> lock the cover cap <NUM> to the wheel cover <NUM> via a snap fit. In another example, the cover cap <NUM> may be attached via other mechanical mechanisms or integrated into the wheel cover <NUM>, such that the cover cap <NUM> and the wheel cover <NUM> are one piece. In one example, shown in <FIG>, the cover <NUM> is one integrated piece. Furthermore, the cover cap <NUM>, wheel cover <NUM>, and the plate <NUM> may be one piece as well.

In one implementation, the cover cap <NUM> encloses the center opening <NUM>, creating a smooth surface on the wheel cover <NUM>, which may contribute to aerodynamic efficiency of the wheel cover system <NUM>. The wheel cover <NUM> or integrated cover <NUM> may be covered in a wrap to display an image or have an unobstructed communicative display. The wheel cover <NUM> completely seals and hides the remainder of the wheel cover system <NUM> and the inner wheel components, including the hub <NUM>, from view, while providing protection from dirt and debris.

For an example of the wheel cover system <NUM> configured for mounting to a rear wheel of a vehicle, reference is made to <FIG>. In one implementation, the plate <NUM> attaches to a plate receiver <NUM> via screws, adhesion, rivets, or the like. Raised portions of the plate receiver <NUM> can be seen in <FIG>. In one implementation, the plate <NUM> is screwed into the plate receiver <NUM> with a plurality of screws that screw into a plurality of threaded openings <NUM> in the plate receiver <NUM>. Each of a plurality of curved flanges <NUM> follows a portion of the perimeter of each cap receiving area <NUM>, as shown in <FIG>, which allows the cap <NUM> of the post <NUM> to pass through the cap receiving area <NUM>.

In the illustrated example shown in <FIG>, a standard <NUM> bolt hub assembly is shown with <NUM> studs <NUM> extending outwardly from the hub <NUM>. In the same example, four long posts <NUM> will be engaged to every other stud <NUM>, such that a free stud <NUM> is positioned between each post <NUM>. In other examples, more or less than four posts <NUM> may be used and the posts <NUM> may be installed with any pattern, such as all four posts <NUM> adjacent to each other, two posts <NUM> adjacent to each other, or the like. As previously mentioned, an adhesive, such as Loctite, or other attachment mechanism may be used to secure the posts <NUM> onto the studs <NUM>. The spring <NUM> is then installed onto two posts <NUM>. The plate <NUM> may be attached to the wheel cover <NUM> or integrated into the wheel cover <NUM> as one piece. The cover assembly <NUM> may then be removably installed onto the posts <NUM>.

<FIG> illustrate an example of the wheel cover system <NUM> configured for mounting to a front wheel of a vehicle. Contrary to a rear wheel, a standard front axle may include <NUM> lug nuts deeply recessed within the wheel. To account for these differences, in one implementation, the wheel cover system <NUM> includes the plurality of posts <NUM> with the short profile <NUM>, or an alternative short profile <NUM>, the spring <NUM> with a plurality of limbs, and a modified plate <NUM> and wheel cover <NUM>.

As shown in <FIG>, in one implementation, the post <NUM> with the alternative short profile <NUM> is shown. Each of the posts <NUM> has a first cap <NUM> disposed on an upper portion <NUM> of the post and a second cap <NUM> and a third cap <NUM> to frame a spring step <NUM>. Each of the plurality of posts <NUM> may have a threaded opening on the lower portion <NUM> configured to receive a lug nut of the wheel, which allows the post <NUM> to screw onto the lug nut. In one example implementation, five posts <NUM> are screwed onto the lug nuts of a front axle. The plurality of posts <NUM> are configured to receive and hold the multi-limb spring <NUM>.

Referring to <FIG> and <FIG>, in one implementation, the spring <NUM> includes a plurality of spring limbs <NUM> each extending from a spring cap <NUM> and having the spring hook <NUM>. The amount of spring limbs <NUM> and spring hooks <NUM> depends on the amount of lug nuts of the wheel. In one example implementation, the spring <NUM> has five spring limbs <NUM> extending from the spring cap <NUM>. Each of the spring hooks <NUM> is configured to couple the spring <NUM> to the plurality of posts <NUM>. The spring cap <NUM> includes a spring cap hood <NUM> and a spring cap base <NUM>. The spring cap hood <NUM> has a plurality of grooves <NUM> configured to receive an end <NUM> of each spring limb <NUM> opposite another end having the spring hook <NUM>. Similarly, the spring cap base <NUM> includes a second plurality of grooves <NUM> configured to receive the end of each spring limb <NUM>. The spring cap hood <NUM> and the spring cap base <NUM> can be coupled to each other via adhesion, screws, rivets, snap-fit, welding, or the like. The spring cap <NUM> may double as the spring engagement point <NUM> and a known point of contact during installation in the feedback loop. A contour <NUM> of the plate <NUM>, shown in <FIG> can receive the spring engagement point <NUM>, allowing a user to feel that the wheel cover <NUM> is centered.

In one implementation, the plate <NUM> includes radius cuts of different diameters to engage the steps having different diameters in the plurality of posts <NUM>. In other words, the plate <NUM> positively engages the plurality of posts <NUM> by a precise mating of the radiused plate <NUM> to the radiused plurality of posts <NUM>. The plate <NUM> includes a body with a plurality of hooks <NUM> having a hook receiving area <NUM>, neck receiving area <NUM>, and a cap receiving area <NUM>. The plate <NUM> may also include a plurality of openings <NUM> to reduce weight and material. In one example implementation, the plate <NUM> has five hooks <NUM> protruding from the circumference of the body of the plate <NUM>. The plate <NUM> may also have five openings <NUM> and five corresponding screws <NUM>.

Turning to <FIG>, in one implementation, the wheel cover <NUM> includes a center opening <NUM> and a plurality of couplers <NUM> configured to receive the plate <NUM>. The wheel cover <NUM> may also include a plurality of cap cover receivers <NUM> configured to receive a plurality of cover cap tabs <NUM>, shown in <FIG>. The plurality of couplers <NUM> and the plurality of cap cover receivers <NUM> are positioned in an indented ring <NUM>, shown more clearly in <FIG>. Turning to a bottom view of the alternative wheel cover <NUM>, reference is made to <FIG>.

The bottom portion of the wheel cover <NUM> includes a plate receiver <NUM> having a plurality of threaded openings <NUM> configured to receive a plurality of screws <NUM>. The plurality of threaded openings <NUM> protrude from the indented ring <NUM> and may provide further clearance for the plate <NUM> to couple to the wheel cover <NUM>. The plate <NUM> and the wheel cover <NUM> may be coupled to each other by adhesion, screws, rivets, snap and fit, or the like. The plate <NUM> and the wheel cover <NUM> can also be one unit and manufactured via injection molding or machining, for example.

As illustrated in <FIG>, in one implementation, the wheel cover <NUM> includes a planar surface about a center portion <NUM> and a side surface that angles in a direction radially outwardly from the center <NUM> slopes away from the planar surface towards an edge <NUM>. The wheel cover <NUM> can be various shapes with a variety of ornamental features. The wheel cover <NUM> can be injection molded and the edges can be ground. The center opening <NUM> can be covered with a cover cap <NUM> to provide a smooth exterior surface. The cover cap <NUM>, shown in more detail in <FIG> includes a plurality of cover cap tabs <NUM> for removably engaging the wheel cover <NUM> to cover the center opening <NUM>, as described herein. In one implementation, the cover cap <NUM> has five cover cap tabs <NUM>. The cover cap <NUM> is removable from the wheel cover <NUM>, permitting routine inspection and maintenance of the inner components of the wheel and wheel cover system <NUM> without removing the wheel cover <NUM>.

As illustrated in <FIG>, the cover cap <NUM> may snap onto the center opening of the wheel cover <NUM>. The plate <NUM> can be screwed onto the bottom of the wheel cover <NUM>, which together makes up the wheel cover assembly <NUM>. In one example, five alternative posts <NUM> can be screwed onto five alternating lug nuts of a front axle. The spring <NUM> having five spring limbs <NUM> can be mounted onto the posts <NUM>, which together makes up the receiver <NUM>. The wheel cover assembly <NUM> can then be installed onto the receiver <NUM> as described herein.

<FIG> illustrates example operations <NUM> for installing a wheel cover assembly onto a receiver. An operation <NUM> positions a hook of an engagement plate of a cover assembly over a post of the receiver. An operation <NUM> receives an inward force overcoming a spring bias of a spring of the receiver. An operation <NUM> receives a rotational force in a first rotational direction (e.g., clockwise) guiding the hook about the post. An operation <NUM> generates a first positive feedback in response to the rotational force and the inward force. In one implementation, the first positive feedback is generated in response to contact between the post and the engagement plate, preventing further translational movement in an inward direction and rotational movement in the first rotational direction. An operation <NUM> translates the wheel cover assembly outwards in connection with a second positive feedback generated by the spring bias of the spring. The outward translation locks the wheel cover assembly in position on the receiver.

<FIG> illustrates example operations <NUM> for removal of a wheel cover assembly from a receiver. An operation <NUM> receives an inward force on the wheel cover assembly overcoming a spring bias of a spring of the receiver. An operation <NUM> receives a rotational force in a rotational direction (e.g., counterclockwise). An operation <NUM> disengages a groove of an engagement plate of the wheel cover assembly from a post of the receiver using the inward and rotational forces. An operation <NUM> releases the wheel cover assembly from the receiver using the spring bias of the spring. In other words, the spring bias of the spring translates the wheel cover in an outward direction, releasing it from the receiver.

<FIG> shows an example wheel <NUM> with the receiver <NUM> of the wheel cover system <NUM> mounted to the hub <NUM> and the wheel cover <NUM> of the wheel cover assembly <NUM> shown removed. <FIG> illustrate examples of the wheel cover <NUM> mounted to a rear wheel and front wheel, respectively, of a vehicle, such as a truck.

Turning to <FIG>, a top, tilted view of an example stabilizer assembly <NUM> mounted on the receiver <NUM> of the example wheel cover assembly <NUM> is shown. The stabilizer assembly <NUM> includes a plurality of bars <NUM>. In the illustrated example, the plurality of bars <NUM> includes four bars, although the assembly <NUM> can include less than four bars or more than four bars. In the illustrated example, each of the plurality of bars <NUM> is generally crescent shaped with a first end <NUM> and a second end <NUM> opposite the first end <NUM>. In another example, the portion extending between the first end <NUM> and the second end <NUM> is straight. The second end <NUM> is also a mirror image of the first end <NUM>, though the second end <NUM> can be shaped differently than the first end <NUM> in other examples. In the illustrated example, both the first end <NUM> and the second end <NUM> include a first transition portion <NUM> and a second transition portion <NUM>, respectively, tapering from the bar <NUM> to an open jaw.

Each of the jaws includes a seat having a cylindrical surface <NUM>. The open cylindrical surface <NUM> includes an arc having a radius substantially equal to a radius of the post <NUM>, such that the first end <NUM> and second end <NUM> are substantially flush when in contact with the post <NUM>. In one example, the cylindrical surface <NUM> of each of the first end <NUM> and the second end <NUM> are hex shaped to compliment and receive a hex portion <NUM> of the post <NUM>, though the surface <NUM> can be other shapes or forms. In another example, the cylindrical surface <NUM> has ridges. The cylindrical surface <NUM> may also be textured. Each of the plurality of bars <NUM> has a first aperture <NUM> and a second aperture <NUM> extending through the bar <NUM> at the first transition portion <NUM> and the second transition portion <NUM>, respectively to receive a fastener <NUM>, discussed in more detail below. Each of the plurality of bars <NUM> can be made from a solid material such as a metal, plastic, or the like.

<FIG> is a side, tilted view of the example stabilizer assembly <NUM> shown in <FIG>. During assembly, each of the plurality of bars <NUM> is placed between two adjacent posts <NUM>, with the first end <NUM> contacting one of the posts <NUM> and the second end <NUM> contacting another one of the posts <NUM>. In one example, a first end of a first bar contacts one half of the post while a second end of a second bar contacts the other half of the post. The hex shaped cylindrical surface <NUM> allows the first end <NUM> and the second end <NUM> to simply snap onto the hex portion <NUM> of the post <NUM>, such that a bar can be snapped onto two posts and held in place without additional aid. In other words, the first end <NUM> or the second end <NUM> engage with the hex portion <NUM> of the post <NUM> to positively lock the first end <NUM> or the second end <NUM> to the post <NUM>. The post <NUM> may also be slightly rotated to aid the bar in snapping onto the hex portion <NUM>. Further, the hex shaped surface <NUM> can provide increased friction for the first end <NUM> and the second end <NUM> to engage the hex portion <NUM> of the post <NUM>. In the illustrated example, four bars capture the hex portion <NUM> of each of the four posts and when viewed from above, forms a circle, though more than four or less than four bars may be used in other examples. The fastener <NUM> couples the first end <NUM> of the first bar <NUM> to the second end <NUM> of the second bar <NUM>. The fastener <NUM> can be a hose clamp, cable ties, or the like. In one example, the fastener <NUM> is a stainless steel clip. In the illustrated example, the fastener <NUM> is a zip-tie which is threaded through the first aperture <NUM> of the first bar <NUM> and through the second aperture <NUM> of the second bar <NUM> and tightened such that the first end <NUM> of the first bar <NUM> and the second end <NUM> of the second bar <NUM> contact the stem surface <NUM> and substantially wrap around a circumference of the post <NUM> at the hex portion <NUM>.

The fastener <NUM> exerts a force radially inward against the first end <NUM> of the first bar <NUM> and the second end <NUM> of the second bar <NUM>, which creates an interference fit between the first end <NUM> and the second end <NUM> and the post <NUM>. Stated differently, the fastener <NUM> pushes the first end <NUM> and the second end <NUM> towards the post <NUM>, capturing the post <NUM> between the first end <NUM> and the second end <NUM> and creating a press or friction fit between the first end <NUM> and the second end <NUM> and the post <NUM>. The interference fit prevent the posts from loosening, as well as provides stability to the post as they remain firmly attached. In more detail, when the vehicle is in motion and produces vibrations, the vibrations will be directed to the stability bars instead from the posts, which prevent the posts from becoming loose due to vibrations.

In another example not shown, the first end and the second end can each include a pair of opposing apertures, wherein the pair of opposing apertures align with each other. A pair of nuts and bolts can be fastened through each of the aligned pair of opposing apertures and tightened until the interference fit is produced.

Turning to <FIG>, a top, tilted view of an example locking mechanism <NUM> in an unlocked orientation and a locked orientation and an isometric, exploded view of another example locking mechanism <NUM>, respectively, are illustrated. The locking mechanism <NUM> is positioned on a center of the plate <NUM> and essentially inhibits the wheel cover <NUM> from being pushed inward, thus preventing the wheel cover <NUM> from being rotated and removed from the plate <NUM>. Though the wheel cover <NUM> is shown transparent, the wheel cover <NUM> can be opaque, which can advantageously hide the mechanism of the locking mechanism <NUM>. The locking mechanism <NUM> includes a center mechanism <NUM> that is generally cylindrical shaped and includes a first surface <NUM> and a second surface <NUM>, shown in <FIG>, opposite the first surface <NUM>. The locking mechanism <NUM> includes a pair of bars <NUM> coupled to the center mechanism <NUM> and secured to the center mechanism <NUM> by a receiver receptacle <NUM>.

As shown in <FIG>, a detailed view of a keyway <NUM> disposed on the first surface <NUM> of the center mechanism <NUM> and a corresponding key <NUM> are shown, respectively. The keyway <NUM> includes a ring depression <NUM> extending into the first surface <NUM> and having a center axis equal to a center axis of the center mechanism <NUM>. The ring depression <NUM> defines a keyway surface <NUM> spaced between the first surface <NUM> and the second surface <NUM>. The keyway surface <NUM> includes a plurality of keyway apertures <NUM> circularly spaced around a keyway center <NUM>. The keyway apertures <NUM> may receive a corresponding set of key protrusions <NUM> of the key <NUM> and may capture the set of key protrusions <NUM> so that when the key <NUM> is rotated, the center mechanism <NUM> is also rotated. The keyway center <NUM> protrudes from the keyway surface <NUM> to the first surface <NUM> and may be received by a bore <NUM> of the key <NUM>, which may align the key <NUM> on the keyway <NUM>. A flange <NUM> is disposed on the first surface <NUM> around a perimeter of the ring depression <NUM>, and may be received in a similarly shaped opening on the wheel cover <NUM> to couple the center mechanism <NUM> to the wheel cover <NUM>.

Turning to <FIG>, a detailed bottom view of the center mechanism <NUM>, a detailed top view of the receiver receptacle <NUM>, and a bottom view of the center mechanism <NUM> are respectively shown. The center mechanism <NUM> includes a pair of mirroring and opposing bar cutouts <NUM> extending from the second surface <NUM> towards the first surface <NUM>. Each of the bar cutouts <NUM> define a bar surface <NUM> parallel to the second surface <NUM> and a lock surface <NUM> and an unlock surface <NUM>, both of which are perpendicular to the bar surface <NUM>. Further, the lock surface <NUM> and the unlock surface <NUM> are perpendicular to each other. A bar aperture <NUM> is disposed on the bar surface <NUM> and is parallel to the center axis of the center mechanism. The bar aperture <NUM> is operable to receive an extension <NUM> of the bar <NUM>, thereby coupling the bar <NUM> to the center mechanism <NUM>. The extension <NUM> is bent <NUM> degrees from the bar <NUM> and may have a length shorter than a length of the bar <NUM>. The extension <NUM> may have a further elastomeric extension <NUM> on a top of the extension <NUM>. The elastomeric extension <NUM> may also be a separate piece, as illustrated. The elastomeric extension <NUM> is positioned in the bar aperture <NUM> prior to the extension <NUM> and provides a spring resistance to provide feedback to the user during use. The bar cutout <NUM> is shaped to provide a space for the bar <NUM> to move through when the center mechanism <NUM> is rotated.

The center mechanism <NUM> also includes an alignment depression <NUM> extending into the second surface <NUM> and defining a first alignment surface <NUM>. The alignment depression <NUM> is generally rectangular shaped and is sized to receive a corresponding alignment protrusion <NUM> of the receiver receptacle <NUM> to align the receiver receptacle <NUM> to the center mechanism <NUM>. The alignment protrusion <NUM> protrudes from a first receiver surface <NUM> and defines a second alignment surface <NUM>, which contacts the first alignment surface <NUM> when the receptacle <NUM> is aligned with the center mechanism <NUM>. The receiver receptacle <NUM> also includes a pair of detents having a first detent <NUM> and a second detent <NUM>. In one example the first detent <NUM> is longer than the second detent <NUM>, though the first detent <NUM> and the second detent <NUM> can be the same length or the second detent <NUM> can be longer than the first detent <NUM>. The pair of detents <NUM>, <NUM> receives the pair of bars <NUM> and provides a feedback loop to the user indicating when the lock or unlock position has been achieved, with the first detent <NUM> indicating that the pair of bars <NUM> is in the in the unlock orientation and the second detent <NUM> indicating that the pair of bars <NUM> is in the lock orientation. The receiver receptacle <NUM> also includes a second alignment aperture <NUM>, which extends through the receptacle <NUM> from a second receiver surface to the first receiver surface <NUM> and aligns with a first alignment aperture <NUM> of the center mechanism <NUM>. The first alignment aperture <NUM> and the second alignment aperture <NUM> receive an alignment fastener <NUM>, which secures the receiver receptacle <NUM> to the center mechanism <NUM>, thereby also securing the pair of bars <NUM> between the center mechanism <NUM> and the receiver receptacle <NUM>. The alignment fastener <NUM> can further be received by the center opening <NUM> of the plate, thereby securing the locking assembly <NUM> to the plate <NUM>.

The locking assembly <NUM> may include a pair of supporting brackets <NUM> shown in <FIG>. The supporting brackets <NUM> can be separate pieces coupled to the plate <NUM>, as shown in <FIG> or may be formed on the plate <NUM> directly, as shown in <FIG>. Further, the locking mechanism <NUM> may include no brackets, one bracket, or more than two brackets.

In use, a user inserts the key <NUM> into the keyway <NUM> and rotates the key <NUM>, thereby rotating the center mechanism <NUM>. When the center mechanism <NUM> is rotated in a first direction, e.g. counter-clockwise, each of the pair of bars <NUM> is retracted towards the center mechanism <NUM> and away from two opposing posts <NUM>, defining the unlocked orientation shown in <FIG>. In the unlocked orientation, the pair of bars <NUM> are parallel to the unlock surface <NUM> and are positioned in the first detent <NUM>. The bars <NUM> do not impede the wheel cover <NUM> from being pushed down and rotated off of the opposing posts <NUM> in the unlocked orientation. Conversely, when the center mechanism <NUM> is rotated in a second direction, e.g. clockwise, each of the pair of bars <NUM> are pushed away from the center mechanism <NUM>, through the pair of supporting brackets <NUM>, and towards the two opposing posts <NUM>. In the locked orientation, the pair of bars <NUM> are parallel to the lock surface <NUM> and are positioned in second detent <NUM>.

To lock the locking mechanism, the key <NUM> is rotated clockwise to rotate the center mechanism <NUM> and push the pair of bars <NUM> into a space between the two opposing post <NUM> and the wheel cover <NUM>. In the locked orientation, shown in <FIG>, each of the pair of bars <NUM> is positioned above the top surface <NUM> of each of the two opposing posts <NUM>. In the locked orientation, the wheel cover <NUM> cannot be pushed down and rotated off of the posts <NUM>, as the pair of bars <NUM> physically obstruct the wheel cover <NUM>. Stated differently, the pair of bars <NUM> physically obstruct the inward path of the wheel cover <NUM> and prevent the wheel cover <NUM> from being pushed towards the plate <NUM>. To unlock the locking mechanism <NUM>, the key <NUM> is rotated counter-clockwise to remove the pair of bars <NUM> from the space between the two opposing post <NUM> and the wheel cover <NUM>.

Although the locking mechanism <NUM> is shown with a pair of bars, the locking mechanism can include any number of bars including one bar or more than two bars. For example, the locking mechanism can include four bars, with each of the four bars extending over the top surface <NUM> of four posts.

Turning to <FIG> and <FIG>, another implementation of a wheel cover system <NUM> with a wheel cover <NUM> and a detailed view of a receiver <NUM> and an engagement plate <NUM> are shown respectively. The system <NUM> includes the engagement plate <NUM> coupled to the wheel cover <NUM>. In one implementation, the wheel cover <NUM> contacts the wheel and/or the rim. In another implementation, the wheel cover <NUM> does not contact the wheel and/or the rim. The wheel cover <NUM> includes a plurality of protrusions <NUM> disposed on a plurality of columns <NUM>. Such protrusions <NUM> are received by a plurality of apertures <NUM> disposed on the plate <NUM>. The protrusions <NUM> may be secured to the plurality of apertures <NUM> by adhesion or a press fit, thereby securing the wheel cover <NUM> to the plate <NUM>. The plurality of columns <NUM> may be secured to the wheel cover <NUM> by adhesion or the wheel cover <NUM> and may be manufactured as one piece with the wheel cover <NUM> (e.g., machined from a solid or injection molded). Similarly, the plurality of protrusions <NUM> and the plurality of columns <NUM> may be one piece or multiple pieces secured to each other.

In use, the plate <NUM> is received by the receiver <NUM>, thereby coupling the wheel cover <NUM> to a wheel of a vehicle. The receiver <NUM> includes a plurality of posts <NUM> secured to a plurality of lug nuts <NUM> that are threaded to a plurality of studs <NUM>. The studs <NUM> may be coupled to a hub (not shown) of a vehicle (i.e., a passenger vehicle). Alternatively, each of the plurality of posts <NUM> may be secured to a wheel bolt which threads into a hub of a vehicle (i.e., a passenger vehicle). The receiver <NUM> also includes a spring <NUM> that provides both positive feedback to a user and a spring bias to lock the wheel cover <NUM> to the receiver <NUM>.

<FIG> illustrates one of the plurality of posts <NUM> secured to the lug nut <NUM>. Each post <NUM> may be secured to the lug nut <NUM> by adhesion or the post <NUM> and the lug nut <NUM> may be machined as one piece. Similarly, in one implementation, each post <NUM> may be secured to a wheel bolt by adhesion, or the post <NUM> and the wheel bolt may be machined as one piece. In the illustrated example, the post <NUM> includes a stem <NUM> extending from the lug nut <NUM> to a neck <NUM>. A diameter of the neck <NUM> is greater than a diameter of the stem <NUM> and less than a diameter of the cap <NUM>. A cap <NUM> is disposed at an end of the post <NUM>. The stem <NUM> includes a taper at a transition between the neck <NUM> and the stem <NUM>.

<FIG> illustrates the plurality of posts <NUM>, lug nuts <NUM>, and studs <NUM> (not visible), and spring <NUM> assembled onto an example rim <NUM>. In the illustrated example, the plurality of posts <NUM> include five posts <NUM> arranged in a star pattern. The plurality of posts <NUM> may include one, two, or more than two posts <NUM> and may be arranged in any pattern. The number of posts and the pattern may include patterns of typical passenger vehicles. Also shown in the illustrated example, the spring <NUM> may be disposed in a well <NUM> of the rim <NUM> and adhered or frictionally engaged to the well <NUM>. The varying diameters of each post <NUM> correspond to varying diameter cuts of the plate <NUM>, and coupled with the spring <NUM>, receive and lock the plate <NUM> to rim <NUM>.

<FIG> illustrates the plate <NUM> engaged with the plurality of posts <NUM>. The illustrated plate <NUM> is circular, though the plate <NUM> may be any size or shape including, but not limited to, a square, an oval, a rectangle, a star, a diamond, or the like. The plate <NUM> may be any solid material such as a metal or plastic, and may be machined or injection molded. The plate <NUM> includes a plurality of openings <NUM> and the plurality of apertures <NUM>, as described and shown in <FIG>. In the illustrated implementation, the plurality of openings <NUM> and the plurality of apertures <NUM> each include five openings <NUM> and five apertures <NUM>, respectively. Each of the five openings <NUM> are disposed in a circular star pattern corresponding to the star pattern of the plurality of posts <NUM>. In the same example, each of the five apertures <NUM> is disposed in a circular star pattern between each of the five openings <NUM>. Each of the plurality of openings <NUM> and the plurality of apertures <NUM> may include one, two, or more than two openings <NUM> and/or apertures <NUM>, respectively, and each may be disposed in any pattern.

Each of the plurality of openings <NUM> include an elongated stem opening <NUM> with a neck opening <NUM> disposed at one end and a cap opening <NUM> at another end. In the illustrated implementation, the neck opening <NUM> and the cap opening <NUM> are semi-circular and the stem opening <NUM> is slightly curved, though the stem opening <NUM>, the neck opening <NUM>, the cap opening <NUM> may be any shape. A width of the stem opening <NUM> corresponds to, and is substantially equal to, the diameter of the stem <NUM>. Similarly, the diameter of the neck opening <NUM> and the cap opening <NUM> correspond to, and are substantially equal to, the diameter of the neck <NUM> and the cap <NUM>. Such corresponding steps in the post <NUM> and diameter cuts in the plate <NUM> provide for engagement of the plate <NUM> with the post <NUM>.

During installation or uninstallation, each of the posts <NUM> are received by each of the cap openings <NUM> and the plate <NUM> receives a force to move the plate <NUM> below both the cap <NUM> and the neck <NUM> in a first orientation (i.e. unlocked). The plate <NUM> can be rotated between the first orientation (i.e. unlocked) to a second orientation (i.e. locked), which rotates each of the post <NUM> through each of the stem openings <NUM> to the neck openings <NUM>. The second orientation is defined by each of the posts <NUM> disposed in the neck opening <NUM>, where the plate <NUM> cannot be lifted off of the plurality of posts <NUM> because the diameter of the neck opening <NUM> is less than the diameter of the cap <NUM>. In other words, each of the caps <NUM> prevents the plate <NUM> from being removed from the plurality of posts <NUM>. The corresponding steps in the post <NUM> and diameter cuts in the plate <NUM>, together with a spring bias, locks the plate <NUM> in the second orientation.

<FIG> illustrates the plate <NUM> engaged to the plurality of posts <NUM>, with the spring <NUM> visible. The spring <NUM> provides the spring bias against the plate <NUM>. To move the plate <NUM> from the first orientation to the second orientation, a downward force greater than the spring bias is received by the plate <NUM>, which moves and positioned the plate <NUM> below the cap <NUM> and the neck <NUM> and adjacent to a portion of the stem <NUM>. The plate <NUM> receives a rotational force to move the plate <NUM> from the first orientation to the second orientation (e.g., clockwise). The downward and rotational force are released, and the spring bias pushes the plate <NUM> away from the hub and towards the cap <NUM> of the post <NUM>. In other words, the plate <NUM> receives a positive feedback from the spring <NUM>, which the plate <NUM> against the plurality of posts <NUM>. The spring bias, together with the cap <NUM> of the post <NUM> and the neck opening <NUM> of the plate <NUM>, lock the plate <NUM> in the second orientation. The second orientation is further defined by a top surface <NUM> of the plate <NUM> positively engages a bottom cap surface <NUM> of the cap <NUM>. In the illustrated example, the spring bias is provided by a coil spring <NUM>, though the spring bias may be provided by any spring such as, but not limited to, a leaf spring, a conical spring, a torsion spring, or the like. Also visible in <FIG>, the wheel cover <NUM> shown is disc or domed shaped, although the wheel cover <NUM> may be any shape.

<FIG> illustrates the wheel cover <NUM> disposed on the rim <NUM>. In the illustrated example, the wheel cover <NUM> is the same diameter as the rim <NUM> and provides a smooth surface over the rim <NUM>. Such surface may beneficially increase an aerodynamic efficiency of the wheel cover system <NUM>.

<FIG> illustrates example operations <NUM> for installing a wheel cover assembly onto a receiver. An operation <NUM> positions a first opening of an engagement plate of a cover assembly over a post of the receiver. An operation <NUM> receives an inward force overcoming a spring bias of a spring of the receiver. An operation <NUM> receives a rotational force in a first rotational direction (e.g., clockwise) guiding the engagement plate about the post from the first opening to a second opening. An operation <NUM> generates a first positive feedback in response to the rotational force and the inward force. In one implementation, the first positive feedback is generated in response to contact between the post and the engagement plate, preventing further translational movement in an inward direction and rotational movement in the first rotational direction. An operation <NUM> translates the wheel cover assembly outwards in connection with a second positive feedback generated by the spring bias of the spring. The outward translation locks the wheel cover assembly in position on the receiver.

<FIG> illustrates example operations <NUM> for removal of a wheel cover assembly from a receiver. An operation <NUM> receives an inward force on the wheel cover assembly overcoming a spring bias of a spring of the receiver. An operation <NUM> receives a rotational force in a rotational direction (e.g., counterclockwise). An operation <NUM> disengages an opening of an engagement plate of the wheel cover assembly from a post of the receiver using the inward and rotational forces. An operation <NUM> releases the wheel cover assembly from the receiver using the spring bias of the spring. In other words, the spring bias of the spring translates the wheel cover in an outward direction, releasing it from the receiver.

In addition to <FIG>, various features, including ornamental features, of a passenger vehicle wheel cover, such as the wheel cover assembly <NUM>, may be seen in <FIG>.
