  • Publication number: 20240127771
    Abstract: A shoulder rest (30) for a stringed instrument with a support element (32) extending in a longitudinal direction (L) for resting on the shoulder and/or chest of the player, on which a number of hinged clamping units (34) are arranged, is intended to be adaptable in a particularly simple manner to different geometric requirements. For this purpose, the shaft (50) of the or each clamping unit (34) is mounted in each case by means of integrally formed pivot pins (58) in an associated pivot bearing (55), the bearing shells (60) of which are designed in accordance with the invention in each case in the form of an arc segment which does not engage around or enclose the pivot pin (58) completely, but only over a certain arc length. The shaft is preferably positioned off-center and thus enables particularly simple and fast dimensional adjustments.

  • Patent number: 8618392
    Abstract: An adapter piece (28) for fixing a shoulder rest (30) on a string instrument, having an adapter body (38) provided with at least four clamping fingers (32) engageable with a peripheral bottom edge (12) of the string instrument to be supported, shall keep the tonal impairment of the instrument particularly low, offering, at the same time, a high stability. For this purpose, at least two of the clamping fingers (32) are positioned such that they are engageable with the peripheral bottom edge (12) in the area of the outer blocks (20) of the string instrument.
