  • Patent number: 4238647
    Abstract: A telephone handset is provided which renders possible holding of the handset without hands during conversation and supported on the left or right shoulder of the telephone user. Depending upon whether the handset is supported on the left or right shoulder, adaptation to the outer ear is effected by rotation of the earpiece or a part of it to the left or right. The invention is based upon the combination of two components, namely a shoulder rest which can be placed transversely of the handle part of the handset and a rotatably adjustable earpiece or a part on the latter with oblique contact surface, for adaptation to the left or right human ear.
