Abstract
A wheel ornament assembly (10) includes a nut cap assembly (16) threadingly engaging an externally threaded lug (20) of a vehicle wheel (14). The nut cap assembly (16) retains a decorative wheel ornament (12) to the wheel (14). The nut cap assembly (16) includes an insert member (32) within and non-rotatably fixed to a cap cover (34) to provide desired aesthetics. The insert member (32) includes a threaded interior bore (35) with relief slots (44) therein to allow the walls of the insert member (32) to flex or expand after full threading of the nut cap assembly (16) on the lug nut (20) to prevent stripping of the threads. The cap cover (34) provides clearance to allow flexibility of the insert member (32) while maintaining its fixed connection.
Claims30
A wheel ornament assembly for placement on a vehicular wheel including a projecting externally threaded lug nut, said assembly comprising:
- a wheel ornament;
- a lug opening disposed through said wheel ornament for receiving the projecting externally threaded lug nut from the vehicular wheel;
- a nut cap assembly including an insert member and a cap cover, said cap cover fixedly secured to said insert member to prevent rotation between said cap cover and said insert member;
- said insert member including a generally tubular body with a bore therein and centered over the projecting externally threaded lug nut opening with a lower body portion, an upper body portion, and a retainer flange disposed about said lower body portion and engaging said wheel ornament;
- said lower body portion including an internal threaded portion disposed within said bore for threadably engaging the lug nut to retain said wheel ornament on the vehicular wheel;
- a relief slot extending into said lower body portion to permit circumferential flexibility of said insert member in the area of said internal threaded portion, said cap cover extending over said upper body portion and fixedly secured to said insert member allowing the circumferential flexibility of said insert member at said internal threaded portion.
A nut cap assembly for engaging and covering a threaded lug nut of a vehicular wheel, said nut cap assembly comprising:
- an insert member;
- a cap cover over said insert member such that said cap cover rotates with said insert member with no lost motion therebetween;
- said insert member including a generally tubular body with a bore therein and centered over the lug opening with a lower body portion, an upper body portion, and a retainer flange disposed about said lower body portion and engaging said wheel ornament;
- said lower body portion including an internal threaded portion disposed within said bore for threadably engaging the lug nut to retain said wheel ornament on the vehicular wheel;
- a relief slot extending into said internal threaded portion to permit circumferential flexibility of said insert member in the area of said internal threaded portion, said cap cover extending over said upper body portion and fixedly secured to said insert member allowing the circumferential flexibility of said insert member at said internal threaded portion.
