Earmuff mounting device

A device for mounting an earmuff on an article of headwear, wherein the earmuff comprises a shell for positioning over a wearer's ear, with external mounting formations on opposite sides of the shell, the mounting device comprising:

• an adapter for connection to the article of headwear at a location on the periphery of the article of headwear that, in use, is positioned above a wearer's ear;
• a housing rotatably mounted on the adapter;
• a socket having an inner end mounted in the housing and an open outer end projecting from the housing, wherein the socket is pivotable about an axis in the plane of rotation of the housing and is biased into either a first position in which the socket extends in a direction perpendicular to the axis of rotation of the housing or a second position in which the socket extends at an angle between the axis of rotation of the housing and the direction perpendicular to the axis of rotation;
• and
• a mounting frame comprising a shaft for engagement in the open end of the socket, and a pair of elongate arms extending from the shaft, wherein each arm has an extension with a mounting formation that is engageable with an external mounting formation on the shell, and wherein each extension is axially adjustable on its respective arm, such that when an earmuff is positioned between the arms, the mounting formations on opposite sides of the shell can engage in the mounting formations on respective extensions.
