Abstract

An acoustic headgear-sun visor assembly for use by pilots, users of Walkman-type radio and tape deck assemblies, users of noise attenuation devices and the like. The assembly comprises a headpiece including a flat band support member. A split bolt having a bifurcated shank receives the flat band support member. A sun visor is mounted on the split bolt in an angularly adjustable friction fit, enabling shifting it between operative and inoperative positions.

Claims

1. The acoustic headgear-sun visor assembly comprising in combination:

(a) an acoustic headpiece configured to extend laterally over a head and including a flat band support member at each side of the headpiece,

(b) a pair of split bolts each having a bifurcated, externally threaded shank receiving the flat band support member in the slot between the bifurcations,

(c) a nut threaded on said bifurcated shank releasably securing said flat band support member between said nut and the base of said slot,

(d) sun visor means, and

(e) mounting means mounting the sun visor means on the split bolt.

2. The acoustic headgear-sun visor assembly of claim 1 wherein each flat band support member is a yoke-shaped flat band support member supporting an earphone, the sun visor means comprises an arcuately bent length of clear plastic having a perforation adjacent each end, each perforation receiving the threaded shank of one of the pair of split bolts, and the sun visor mounting means comprises lock nut means on the threaded shank of each split bolt securing the sun visor means thereto in an angularly adjustable friction fit.

3. The acoustic headgear-sun visor assembly of claim 1 wherein each split bolt has a transversely perforated head, the sun visor means comprises an arcuately bent length of clear plastic having a perforation adjacent each end, and the sun visor mounting means comprises nut and bolt means penetrating both the perforation in the split bolt head and the associated perforation in the sun visor means, thereby locking the sun visor means to the split bolt head in an angularly adjustable friction fit.
