Adjustable and foldable shoulder rest for violin or viola

摘要

An adjustable and foldable shoulder rest for a violin or viola includes a shoulder-engaging body having first and second foldable forks at first and second ends of the body for attaching to the violin or viola, first and second slidable end members for supporting the first and second forks, the first and second slidable end members being slidable between retracted and extended position, wherein the first and second slidable end members each comprises a pull-tab adjustment mechanism for relocating a protrusion shaped to engage one of a first plurality of apertures disposed in a slot. The shoulder rest may have a foam cushion with openings attached to the shoulder-engaging side of the shoulder rest. The end members may define rotational housings for receiving respective rotatable drums that receive threaded stems of the forks, thereby enabling the height of the forks to be adjusted and further enabling the forks to fold.
