Abstract

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.

Dependent claims

An adjustable and foldable shoulder rest for a musical instrument, the shoulder rest comprising:

a shoulder-engaging body having a first end and a second end, the body also having a shoulder-engaging side and an instrument-facing side;
a first foldable fork-shaped clamping member disposed at the first end for clamping the musical instrument, wherein the first clamping member is foldable from an unfolded position to a folded position;
a second foldable fork-shaped clamping member disposed at a second end for clamping the musical instrument, wherein the second clamping member is foldable from an unfolded position to a folded position;
a first slidable end member for receiving a first threaded stem that supports the first clamping member, the first slidable end member being slidable between a retracted position and an extended position, the first slidable end member also having a first arcuate channel through which the first stem rotates as the first clamping member is pivoted between the unfolded and folded positions, wherein the first slidable end member is slidable within a first slot in the instrument-facing side of the body to extend or retract the first clamping member;
a second slidable end member for receiving a second threaded stem that supports the second clamping member, the second slidable end member being slidable between a retracted position and an extended position, the second slidable end member also having a second arcuate channel through which the second stem rotates as the second clamping member is pivoted between the unfolded and folded positions, wherein the second slidable end member is slidable within a second slot in the instrument-facing side of the body to extend or retract the second clamping member;
wherein the first slidable end member comprises a first protrusion shaped to engage one of a first plurality of apertures disposed in the first slot;
and
wherein the second slidable end member comprises a second protrusion shaped to engage one of a second plurality of apertures disposed in the second slot.
