Abstract

The present patent application relates to a bow mechanism for string instruments, designed for continuous and controlled sound production. The mechanism comprises a rotating wheel encircled by a circumferential layer, where a first portion is tightly secured around the wheel and a second portion extends outward, forming a gap. When the wheel rotates and the second portion is pressed against at least one string, vibrations are induced, producing sound. In some embodiments, the wheel is elastic, enhancing flexibility during bowing. In further embodiments, the circumferential layer is wrapped with natural or synthetic hair strands, secured by interweaving, anchoring, or a tension-locking mechanism, mimicking traditional bow hair for improved friction and tonal control. The mechanism is adaptable for various string instruments, including violins, cellos, and guitars, for both acoustic and electric applications.

Dependent claims

A bow mechanism for string instruments, comprising:

a shaft configured to be rotated by a rotation mechanism around a rotation axis;
a wheel installed around said shaft, having a diameter greater than the diameter of said shaft and configured to be rotated by said shaft around said rotation axis, wherein said wheel comprises a rigid circumferential surface;
an elastic circumferential layer disposed around said wheel, wherein said elastic circumferential layer comprises at least:
a first portion secured tightly around said rigid circumferential surface;
a second portion extending radially outward from said first portion to define a gap between said first portion and said second portion;
wherein said second portion is configured to deform elastically toward said first portion when pressed against at least one string of a string instrument, such deformation being limited by said rigid circumferential surface beneath said first portion, thereby emulating the behavior of a string instrument bow;
and
wherein rotation of said wheel while said second portion is pressed against at least one string of a string instrument excites vibration of said at least one string to produce sound.
