ABSTRACT:
A hardhat mount assembly (12) is provided for mounting a speaker device (14) on a hardhat (10), that allows adjustment of the speaker device position to allow the worker to choose a comfortable position. The mount assembly includes an inner mount part (50) for mounting on the hardhat, a linkage (100) having an upper end pivotally connected to the inner mount part and a lower end pivotally connected to the speaker device, both pivot connections having pivot axes extending in forward and rearward directions. One inner mount device includes a pair of wings (52, 54) with Velcro (74) on their inner surfaces that attach to Velcro pads (80, 82) that have been mounted with contact adhesive on a side of the hardhat. Another inner mount device includes a pair of plates (210, 212) with adjacent edges (214, 216) hinged together and distant ends (220, 222) that can be latched together to clamp a sweatband (202) of the hardhat lining between them. Another inner mount device (130) has a U-shaped part that straddles a thickened lip (132) at the side of a hardhat, and has at least one screw (150) that screws against the hardhat at a location adjacent to the stepped thickness of the hardhat lip.
