ABSTRACT:
The keys for toy musical instruments comprises a plurality of keys that are friction-fitted on a pair of supports. Each key is an integrally formed, molded member comprised of several components with interrelated functions, such as (1) a key lever for manual depression, (2) a hammer at the end remote from the key lever, (3) a flexible segment for propelling the hammer against a tone bar in response to depression of a key lever, and (4) unique cooperating members on the flexible segment and key lever for damping out reverberations of the hammer that might cause repeated strikings of the tone bar and/or chattering of the hammer.
