Tension-adjustable mechanism for stethoscope earpieces
First Claim
1. A tension-adjusting mechanism for an elongated 0stethoscope earpiece having a proximal end, comprising:
- a stethoscope neckpiece;
a pivot mechanism portion interposed between the proximal end of the earpiece and the neckpiece, and defining a pivot axis about which the earpiece pivots relative to the neckpiece;
a spring mechanism portion interposed between the proximal end of the earpiece and the neckpiece, said spring mechanism portion comprising a spring member which deforms upon pivoting of the earpiece about the neckpiece in an outward direction, wherein deformation of the spring member produces a tension on the earpiece opposing to further pivoting of the earpiece in the outward direction; and
a tension-adjusting mechanism portion interposed between the spring member and the neckpiece and defining a plurality of interchangeable point of contacts with the spring member, said points of contacts with the spring member having different positions relative to the neckpiece.

Abstract
A tension-adjusting mechanism for the elongated earpieces of a stethoscope comprises a neckpiece and, for each earpiece, a pivot mechanism portion between the proximal end of the earpiece and the neckpiece, a spring mechanism portion between the proximal end of the earpiece and the neckpiece, and a tension-adjusting mechanism portion between the spring member and the neckpiece. For each earpiece, the pivot mechanism portion defines a pivot axis about which the earpiece pivots, and the spring mechanism portion comprises a resilient blade deforming upon spreading apart of the earpieces. This deformation produces a tension on the earpieces opposing to further spreading apart thereof. The tension-adjusting mechanism portion defines a plurality of interchangeable point of contacts with the resilient blades, which contact points having different positions relative to the neckpiece.
