Publication number: 20240127771Abstract: 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.Type: ApplicationFiled: February 15, 2022Publication date: April 18, 2024Inventor: Berent Korfker
