Abstract: A shoulder rest for a violin or viola comprises a bridge beam having a first end and a second end and a shoulder-engaging pad mounted to a block having a beam-engaging portion that is shaped to slide over the bridge beam. The shoulder rest includes a first foot disposed at the first end for gripping the violin or viola and a second foot disposed at the second end for gripping the violin or viola. In another implementation, the shoulder rest includes a first shoulder-engaging pad mounted to a first arm that is connected to an arm carriage disposed within a groove in the bridge beam and a second shoulder-engaging pad mounted to a second arm that is connected to the arm carriage.

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. In the extended position, the end member is cantilevered beyond its respective 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.

Abstract: The inventive clamping member is a rigid clamp having a generally “U”-shaped configuration the base of which is defined by two arms each terminating in an upwardly directed clamping finger adapted to engage the rim of a bottom of a violin or the like at opposed sides of the body of the instrument. A pivot, usually in the form of a threaded stem projects from the base of the “U” in a direction opposite to that of the projection of the clamping fingers. It normally secures free pivotal mounting of the clamping members at the ends of a shoulder rest bridge. The stem defines an axis of pivot of the clamping member which is offset to one of the clamping fingers, whereby the two arms are of uneven length. The shorter arm is relatively proximal to the tail of the instrument, while the longer arm is relatively distal from the tail.

Abstract: The distance between the clamps at opposed ends of a shoulder rest bridge adjustable in infinitely fine increments by utilizing a pressure plate which, in an engaged mode, presses a brake member made from an elastomer, particularly soft rubber, against the underside of the bridge body. The pressure plate is actuated by a pivotable latch having a lever and co-operating with a non-rotatable bearing member having a ramp surface complementary in the direction of incline and in pitch with the ramp surface of the pivotable latch. A supplementary camming mechanism provides, upon hand displacement of one of the clamps towards the other into engagement by both with the instrument, an additional motion of the one clamp toward the instrument thus increasing the clamping force holding the shoulder rest to an instrument.

Abstract: The disclosed bridge (10) of a violin or viola shoulder rest is made from a laminate of wood veneers (23-29) the grain of which alternates generally at right angles to each other. In the embodiment disclosed, the number of veneers is seven. The top veneer (23) and the bottom veneer (29) have their grain oriented generally longitudinally of the bridge (10).

Abstract: The adjustment of the distance between clamping elements (13, 14) of a shoulder rest for violin or the like instrument is effected by a stem-like fastener, preferably a thumbscrew (37) passing through one of generally equidistantly spaced apart openings (29, 30) in a foot member (17) and through that opening (29, 30) which is aligned with one of at least two nuts (33, 34) embedded in an elongated base (10) of the shoulder rest.According to the invention, the longitudinal spacing between the openings (29, 30) differs from that of the nuts (33, 34) preferably such that one spacing is one-half of the other, whereby a fine adjustment of the clamping distance can be achieved, while the number of the nuts (33, 34) and/or the openings (29, 30) is relatively small, in the embodiment shown, two of each, permitting a total of four different adjustments of the clamping distance.

Abstract: A violin, viola or the like shoulder rest has a firm elongated base (21,81) provided at each end thereof with an upwardly projecting support of a clamping assembly (38-41; 88-90; 96-98) for securement of the shoulder rest to a violin or viola. The supports are firmly held by the base but are foldable such that the clamps (38-41; 88-90; 96-98) are pivoted toward each other and on top of the base (21, 81) into a generally flush arrangement with the top surface (22) of the base to facilitate storage of the shoulder rest when not in use. Two preferred embodiments are dislosed.
