ABSTRACT:
An improved disk-tumbler lock and key for use with a gun-lock device includes a key specifically adapted to be ring-mounted so that it may be worn by and is thus available for the user at all times. The particular shape of the key includes those characteristics which would be desirable for such a key which will function as a ring for the most part, including a sufficient strength to endure physical abuse resulting from common use as a ring, attractive appearance so that the user would be willing to wear it for extended periods, and an inconspicuous jewelry-like appearance to avoid unwarranted attention. In addition, the particular shape of the key and the mating keyway in the lock assembly are aimed at further improving the speed and reliability at which the key may be inserted into the lock assembly aided only by the user's tactile senses. The physical shape also lends itself to be easily and inexpensively manufactured using various fabrication processes.
