Abstract
Methods and apparatus for attaching a center cap a wheel of a motor vehicle. A specialized lug nut may replace existing lug nuts to provide a threaded receiving area for a screw. The screw may be used to secure a cap in place. Some embodiments include an adapter to match a lug bolt pattern to a cap diameter size. In preferred embodiments, a lug nut is provided of specific designs, size and shape to be installable to act as a mechanism to secure a wheel to a vehicle and also act as a holder for the screw to retain the cap. The center cap may then slide onto the lug nuts (or extension that attach to the lug nuts) and then stay on by tightening a screw through the top of one or more lug nuts on each wheel.
Claims19
An adaptable center cap system for attachment to a wheel, the system comprising:
- a center cap, comprising one or more lug holes arranged across a surface of the center cap, wherein the lug holes extend in an axial direction through a body of the center cap:
- a first spacer for insertion into at least one of the lug holes, wherein the spacer comprises an upper cylindrical portion having a first outside diameter, a lower cylindrical portion having a second outside diameter, and a cylindrical hole extending through the respective upper cylindrical portion and the lower cylindrical portion;
- an adaptor lug nut, comprising a slot adapted to receive a screw, a threaded cavity suitable for attachment to a lug on a car, and a longitudinal pattern of grooves on a longitudinal surface of the adaptor lug nut;
- and
- the screw extending through one of the lug holes in the center cap, the spacer, and an end of the adaptor lug nut.
A method for adapting a center cap to a nonstandard wheel, the method comprising the steps of:
- inserting a spacer into respective center cap holes on the center cap, wherein the locations of the respective center cap holes correspond with respective locations of lug holes on the nonstandard wheel, and wherein the spacer comprises an upper substantially circular portion with a first outside diameter and a lower substantially circular portion with a second outside diameter;
- inserting a proximate end of an adaptor lug nut into the spacer, wherein each adaptor lug nut comprises a threaded cavity for receiving a screw and a longitudinal groove;
- inserting a distal end of each respective adaptor lug nut into the respective lug hole on the nonstandard wheel;
- inserting the screw into a respective center cap hole, through the spacer, and into the threaded cavity, on the proximate end of the adaptor lug nut;
- and
- tightening the screw to cause the center cap to sit in a substantially flush manner on a face of the nonstandard wheel.
