ABSTRACT:
An improved multi-leaf spring assembly is provided that permits greater flexibility and smoother, smaller folding of a stethoscope without deforming an individual user's adjustment. The spring leaves are held together at the ends by a spring clip. A cylindrical ferrule at each end of one leaf snaps into a groove in the lower end of an ear tube and is secured against removal by a spring clip. The entire assembly is encapsulated in an elastomer material to maintain the assembled parts in position while allowing swiveling of the ear tubes.
