发明名称 Telephone handset with integral shoulder rest
摘要 A shoulder rest that forms an integral part of a telephone handset. The rest includes a pair of arms each pivotally connected at one end to the handset body, and a shoulder plate that is pivotally connected between the free ends of the arms. The rest approximates a parallelogram and is spring loaded so that it flips from its folded down position along the handset to its opened up position extending away from the body when a latch on the handset is released.
