Abstract: A security locking system primarily for use in the locking of a threaded retaining member onto a vehicle wheel. In one embodiment, the threaded retaining member may adopt the form of wheel lug nuts which are threaded onto the threaded studs of a vehicle wheel. The locking system comprises a sleeve or so-called "cover" extendable over the retaining member. A locking mechanism is mounted in an end wall of the sleeve. The locking mechanism is provided with a locking element which is extendable radially for engagement with a groove in the wheel lug and provides a positive locking action. The locking mechanism is provided with a cylindrically shaped key slot and has projections in the key slot. A key is provided with certain grooves alignable with the projections in the key slot to receive the key such that only the key having the aligned and properly sized recesses can be used to open and close the locking element. In this way, a conventional tumbler system normally used in most vehice wheel locks can be avoided.

Abstract: A solar radiation protecting device for protecting the forearm and perhaps a portion of an upper arm of an individual when the arm of that individual projects outwardly of a vehicle window while the passenger or driver is seated within the vehicle. This protective device will protect against excessive solar radiation exposure when the arm is so projected beyond the window of the vehicle and thereupon exposed to solar radiation. The protecting device comprises a flexible fabric covering which extends over at least a portion of the forearm of the individual and also permits air exposure to the skin while worn. Strap means are located on the flexible fabric covering for releasably securing the fabric covering to the forearm of the individual.
