Many production vehicle wheels include a center or button cap to aesthetically cover the wheel bearing and, in some embodiments, the lug nuts of the wheel. Generally, a center cap extends radially out and over the lug nuts and a button cap does not extend radially beyond the lug nuts. The center cap is typically attached via a plurality of tabs that extend from the outer edge center cap towards the wheel and fit into a wheel cap retention hole or opening in the wheel plate of the wheel. The tabs interlock with a portion of the wheel to secure the center cap to the wheel. The center cap can be easily removed to provide access to the wheel bearing or to the lug nuts.
Exemplary embodiments discussed below replace the center or button cap with a wheel lock device that is configured to cover and surround the exposed lug nuts of the wheel without changing the character of the wheel design. The wheel lock device attaches to the wheel with one or more tabs that extend into the existing wheel cap retention hole typically used to retain the center or button cap. In some embodiments, three (3) tabs are used to radially locate the wheel lock device. The wheel lock device locks into place on the wheel plate using one or more keyed locks to prevent direct access to the lug nuts.
With reference to
In the embodiment shown in
As discussed above, the wheel lock device 20 replaces the center or button cap to prevent access to the lug nuts of the wheel. The wheel lock device 20 includes a circular area 23 centered on a center axis 102 of the lockable plate 21 (see
The wheel lock device 20 also includes a locking mechanism 16 that extends through an opening in the lockable plate 21. In some embodiments, the locking mechanism 16 is a cylindrical locking mechanism configured to be locked and unlocked with a key. The locking mechanism 16 includes a head portion 17 that extends outward from the outer surface 24 of the lockable plate 21 and a cylindrical portion 18 that extends through the plate 21 and past the inner surface 26 of the lockable plate 21. A lock 37 is connected to the cylindrical portion 18. In some embodiments, the lock 37 is a Z-shaped tab that, when in the locked position, engages with an inboard surface of the wheel plate adjacent to the center/button cap retention hole in the wheel plate. The lock 37 also engages with a slot 33 on the elongated radial locating portion 34 of the tab 32. Engagement of the lock 37 in the slot 33 strengthens the lock 37 and limits movement of the lock 37 relative to the retention tab 32.
Rotation of a key in the locking mechanism 16 rotates the lock 37 along an axis 104 (see
In some embodiments, the lug nuts 72 of the vehicle are replaced with locking lug nuts of a standard type. Use of locking lug nuts with the wheel lock device 20 further increases the protection against possible theft of the vehicle wheels. In some embodiments, the wheel lock device 20 is used as a temporary theft prevention measure during vehicle transport, such as between the assembly plant and the point of sale. The wheel lock device 20 is easily installed by replacing the wheel center cap or button cap with the wheel lock device 20 and locking the device to the vehicle wheel using a simple, keyed lock. When installed, the wheel lock device 20 does not contact the ground or any other part of the vehicle, allowing the wheels of the vehicle to rotate during normal operation, towing, etc.
In some embodiments the wheel lock device 20 is made from a durable and rigid material such as a metal or metal alloy. In some embodiments, for example and without limitation, the wheel lock device 20 is made from high strength steel or aircraft grade aluminum (T6-6061). In some embodiments, the lug nut enclosures 22 and the retention tabs 32 are welded to the underside 26 of the plate 21. In some embodiments, the plate 21, lug nut enclosures, and the retention tabs 32 are formed as a single piece from a mold or casting. In some embodiments, one or more components of the wheel lock device 20, for example and without limitation, the retention tabs 32 and the lug nut enclosures 22, are lined with a non-marring material, such as, for example and without limitation, a polymer coating or rubber, to prevent damage to the wheel and/or the lug nuts.
The embodiments discussed herein may be used to prevent access to the lug nuts of a vehicle wheel as installed on a vehicle. The embodiments discussed herein may also be used with wheel mounted on spare tire racks to reduce or prevent theft of spare tires mounted on a vehicle.
It should be emphasized that many variations and modifications may be made to the herein-described embodiments the elements of which are to be understood as being among other acceptable examples. All such modifications and variations are intended to be included herein within the scope of this disclosure and protected by the following claims. Moreover, any of the steps described herein can be performed simultaneously or in an order different from the steps as ordered herein. Moreover, as should be apparent, the features and attributes of the specific embodiments disclosed herein may be combined in different ways to form additional embodiments, all of which fall within the scope of the present disclosure.
Conditional language used herein, such as, among others, “can,” “could,” “might,” “may,” “e.g.,” and the like, unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments include, while other embodiments do not include, certain features, elements and/or states. Thus, such conditional language is not generally intended to imply that features, elements and/or states are in any way required for one or more embodiments or that one or more embodiments necessarily include logic for deciding, with or without author input or prompting, whether these features, elements and/or states are included or are to be performed in any particular embodiment.
Moreover, the following terminology may have been used herein. The singular forms “a,” “an,” and “the” include plural referents unless the context dearly dictates otherwise. Thus, for example, reference to an item includes reference to one or more items. The term “ones” refers to one, two, or more, and generally applies to the selection of some or all of a quantity. The term “plurality” refers to two or more of an item. The term “about” or “approximately” means that quantities, dimensions, sizes, formulations, parameters, shapes and other characteristics need not be exact, but may be approximated and/or larger or smaller, as desired, reflecting acceptable tolerances, conversion factors, rounding off, measurement error and the like and other factors known to those of skill in the art. The term “substantially” means that the recited characteristic, parameter, or value need not be achieved exactly, but that deviations or variations, including fix example, tolerances, measurement error, measurement accuracy limitations and other factors known to those of skill in the art, may occur in amounts that do not preclude the effect the characteristic was intended to provide.
Numerical data may be expressed or presented herein in a range format. It is to be understood that such a range format is used merely for convenience and brevity and thus should be interpreted flexibly to include not only the numerical values explicitly recited as the limits of the range, but also interpreted to include all of the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. As an illustration, a numerical range of “about 1 to 5” should be interpreted to include not only the explicitly recited values of about 1 to about 5, but should also be interpreted to also include individual values and sub-ranges within the indicated range. Thus, included in this numerical range are individual values such as 2, 3 and 4 and sub-ranges such as “about 1 to about 3,” “about 2 to about 4” and “about 3 to about 5,” “1 to 3,” “2 to 4,” “3 to 5,” etc. This same principle applies to ranges reciting only one numerical value (e.g., “greater than about 1”) and should apply regardless of the breadth of the range or the characteristics being described. A plurality of items may be presented in a common list for convenience. However, these lists should be construed as though each member of the list is individually identified as a separate and unique member. Thus, no individual member of such list should be construed as a de facto equivalent of any other member of the same list solely based on their presentation in a common group without indications to the contrary. Furthermore, where the terms “and” and “or” are used in conjunction with a list of items, they are to be interpreted broadly, in that any one or more of the listed items may be used alone or in combination with other listed items. The term “alternatively” refers to selection of one of two or more alternatives, and is not intended to limit the selection to only those listed alternatives or to only one a the listed alternatives at a time, unless the context dearly indicates otherwise.
While exemplary embodiments are described above, it is not intended that these embodiments describe all possible forms encompassed by the claims. The words used in the specification are words of description rather than limitation, and it is understood that various changes can be made without departing from the spirit and scope of the disclosure. As previously described, the features of various embodiments can be combined to form further exemplary aspects of the present disclosure that may not be explicitly described or illustrated. While various embodiments could have been described as providing advantages or being preferred over other embodiments or prior art implementations with respect to one or more desired characteristics, those of ordinary skill in the art recognize that one or more features or characteristics can be compromised to achieve desired overall system attributes, which depend on the specific application and implementation. These attributes can include, but are not limited to cost, strength, durability, life cycle cost, marketability, appearance, packaging, size, serviceability, weight, manufacturability, ease of assembly, etc. As such, embodiments described as less desirable than other embodiments or prior art implementations with respect to one or more characteristics are not outside the scope of the disclosure and can be desirable for particular applications.
