LOW-FRICTION BRIDGE FOR STRINGED INSTRUMENT

摘要

A low-friction bridge for a stringed musical instrument employs a roller saddle that is adapted and positioned to roll upon a race. The race includes structure to guide the roller saddle as it rolls. A musical string is seated in a circumferential groove/saddle formed in the roller saddle. As the musical string stretches or contracts the saddle rolls, and thus the musical string does not slide in the saddle. As such sliding friction is avoided in favor of rolling friction of the roller saddle rolling upon the race. One or more contact members can be biased into contact with side faces of the roller saddle.

主权项

1. A low-friction musical string support, comprising:
a roller configured to roll within a race defined by opposing first and second race side walls, the roller having opposing first and second side faces that face the opposing first and second race side walls, respectively, the roller further having a circumferential groove configured to accommodate a musical string seated therein; a first contact member interposed between the first race side wall and the first side face of the roller; and a biasing member configured to urge the first contact member into contact with the first side face of the roller; wherein when the string moves longitudinally, the roller rolls within the race.
