Abstract

An earcup suspension for a headphone includes a housing, having a vertically oriented slot and stationarily mounted on the lower end of a headband to be disposed over the top of the headphone user, an earcup mounting includes a vertical member slidably extending through the slot in the housing and having a rack surface configured to coact with a similarly configured inwardly biased detenting rack stationarily disposed in the slot whereby the earcup mounting may be adjusted vertically with respect to the lower ends of the headband.

Claims

1. In a headset including a headband having at least one lower end and an earcup depending therefrom, vertical adjustment apparatus comprising in combination;

a housing having a vertically disposed slot, stationarily mounted on the lower end of a headphone headband;

earcup mounting means having a vertically extending member, vertically, slidably disposed in said slot and including an inwardly facing rack; and

detenting means, including an inwardly extending rack having at least two teeth disposed on a rearwardly extending portion stationarily disposed in said slot and in facing engagement with said rack.

2. The subject matter of claim 1 in which biasing means are disposed intermediate the rearwardly extending portion of the detenting means and an inner portion of the slot in the housing.

3. The subject matter of claim 2 in which the biasing means is comprised of a V shaped spring.

4. The subject matter of claim 3 in which the headband includes an aperture adjacent the lower end and the housing includes a rectractable locking member adapted to removeably engage the aperture.

5. The subject matter of claim 4 in which the rack is comprised of a longitudinally elongated member having a plurality of laterally extending, spaced apart teeth stationarily disposed on the inner surface of the vertically extending member on the earcup mounting means.

6. The subject matter of claim 5 in which the top of the rack extends over the top of the vertically extending member on the earcup mounting means.

7. In a headset including a headband having at least one lower end and an earcup depending therefrom, vertical adjustment apparatus comprising in combination;

a housing, having a vertically disposed slot, stationarily mounted on the lower end of a microphone headband, said headband including an aperture adjacent the lower end thereof and said housing, including a retractable locking member comprised of parallel, longitudinal slots in one major surface thereof, extending upwardly from the lower end of said housing, and adapted to removably engage said aperture;

earcup mounting means, including a vertically extending member, vertically, slidably disposed in said slot and including an inwardly facing rack; and

detenting means disposed in said slot and in facing engagement with said rack.

8. The subject matter of claim 7 in which the locking member includes an inwardly extending boss adjacent the lower end and dimensioned to slidably engage the aperture in the headband.

9. In a headset including a headband having at least one lower end and an ear cup depending therefrom, vertical adjustment apparatus comprising in combination;

a housing, having a vertically disposed slot, stationarily mounted on the lower end of a headphone headband;

earcup mounting means, having a vertically extending member, vertically, slidably disposed in said slot and including an inwardly facing rack comprised of a longitudinally elongated member having a plurality of laterally extending, spaced apart teeth stationarily disposed on the inner surface of the vertically extending member on said earcup mounting means and including a plurality of rearwardly extending portions adapted to engage the vertically extending member on said earcup mounting means; and

detenting means disposed in said slot and in facing engagement with said rack.

10. The subject matter of claim 9 in which the vertically extending member on the earcup mounting means includes a plurality of vertically spaced apart apertures for lockable engagement of the rearwardly extending portions of the rack.

11. The subject matter of claim 10 in which the top of the rack extends over the top of the vertically extending member on the earcup mounting means.
