Bellows holder for accordion

摘要

The accordion bellow holder comprises two opposite levers on the bellows frame. Each end of the levers contains a sawtooth profile. One lever is fixed and the movable lever enables the two levers to interengage by compression of an external key, thus preventing inadvertent bellows opening. Pref. the bellows holder is actuated by a system consisting of various, specified parts, e.g. a spring-loaded pin, or an unsprung but adjustable pin for transfer of the key compression onto the levers. The key protrudes through the side of the base side.
