Headphone with slotted fork on earpiece for end of headband

摘要

The stem (23) of the fork has a transverse wall extending at right angles to the pivot axis with an integral tongue (40) extending into the slot (25). The tongue is formed by a U-shaped opening in the wall with a wedge whose leading surface (41) presents a ramp to the projecting end (17) of the headband (13). The free end of the wedge is rounded to match the hole (18) in the headband. The slot is bounded by two bars (31) extending in the direction of the pivot axis.
