Abstract

The combination of headset receivers (10) and storage system (50) therefor is used in an aircraft passenger entertainment system. Each receiver comprises a housing (12) including electronics for receiving infrared wireless transmission, which is converted into audible signals and supplied to a listener'"'"'s ears through stems (14). Storage of the receivers is in a case (56, 58, 72) having grid plates (74, 76) and a slitted sanitizing pad (78), for receiving and storing the receivers, and for sanitizing their housings and stems.

4. The combination according to claim 3 further including recessed openings in said edge surface for reception of at least one battery and volume and channel controls.

5. The combination according to claim 4 in which said front and rear surfaces have generally rectangular configurations with relatively long base and top edges and relatively short side edges to configure said edge surfaces into relatively thin elongated base and top surfaces and relatively thin short side surfaces, said recessed battery opening extending into said base surface and said recessed control openings extending respectively into said side surfaces.

6. The combination according to claim 5 further including a pair of ears extending from said top surface at its corners with said side surfaces, and a pair of acoustical stems secured to each of said ears for supplying the audible signals to the listener'"'"'s ears.

7. The combination according to claim 6 in which said housing has a decreasing thickness between said front and rear surfaces from lines thereon spaced from said top surface and extending thereto and to said ear portions for aiding insertion of said housing into said port.

12. The combination according to claim 1 in which said sanitizing means comprises a pad of foam moistened with a sanitizing fluid, said pad having slits aligned with said ports and said channel pairs.

13. The combination according to claim 12 further including means for removably retaining said sanitizing pad adjacent to said ports and in said case.

14. The combination according to claim 13 in which said removable retaining means comprises at least a first grid plate having said ports therein and including with said case, a cooperating latching mechanism for releasably securing said first grid plate to said case and said sanitizing pad therebetween.

15. The combination according to claim 14 further including stops in said case, and in which said removable retaining means further comprises a second grid plate having said ports and abuttable against said stops, and forming a sandwich construction with said sanitizing pad and said first grid plate, with said sanitizing pad positioned between said first and second grid plates.

16. The combination according to claim 15 further including a stop bar secured to said case and further within said case then said second grid plate, said stop bar extending transversely to said grid ports and said sanitizing pad slits to provide an abutment and to limit reception of said housings within said case, such that said acoustic stems are extendable beyond said stop bar into said case and that said housings are retained within said grid plates and said sanitizing pad.

17. The combination according to claim 16 further including a handle secured to said case to permit it and its contained housings to be hand carried.

18. The combination according to claim 17 further including means on said case for enabling said case to be stacked with like cases.

19. The combination according to claim 16 wherein said case includes a pair of parallel sides between which said channels extend, said sides having therein respective ones of said sandwich construction of said sanitizing pad and said first and second grid plates latchable to said case and said stop bar, for enabling said housings and acoustical stems to be inserted, sanitized and stored in said case at both said sides thereof.

8. The combination of a headset receiver and storage system therefor for use in an aircraft passenger enertainment system comprising:

a plurality of housings;

a case having a plurality of ports and holders for receiving at most an equal plurality of said housings;

each of said housings being configured generally as a thin parallelepiped having front and rear surfaces joined by edge surfaces, in which said front and rear surfaces are relatively large with respect to said edge surfaces for permitting respective insertion of said housings at their edge surfaces through respective ones of said ports, and including means for receiving electromagnetic signals and for converting the electromagnetic signals into audible signals;

means coupled to each of said housings for supplying the audible signals to a listener'"'"'s ears; and

means adjacent said ports for sanitizing said housings and audible signal supplying means upon insertion thereof into said case.

9. The combination according to claim 8 in which said audible signal supplying means includes acoustical stems secured to each of said housings for supplying the audible signals to the listener'"'"'s ears.

10. The combination according to claim 9 in which said case holders include parallel pairs of channels into which said housings respectively slide and fit for holding said housings respectively within said case, each of said channel pairs being aligned with a respective one of said ports.

11. The combination of headset receivers and a storage system therefor for use by listeners in an aircraft passenger entertainment system comprising:

a plurality of housings, and acoustical stems secured to each of said housings for supplying the audible signals to the listeners'"'"' ears;

a case having a plurality of ports and holders for receiving at most an equal plurality of said housings and acoustical means in which said case holders include parallel pairs of channels into which said housings respectively slide and fit for holding said housings respectively within said case, each of said channel pairs being aligned with a respective one of said ports;

means adjacent said ports for sanitizing said holders and said acoustical stems upon insertion thereof into said case; and

each of said housings being configured generally as a thin parallelepiped whose front and rear surfaces are relatively large with respect to its edge surfaces, for permitting insertion of each of said housings at one of its edge surfaces through a respective one of said ports, and including means for receiving electromagnetic signals, for converting the electromagnetic signals into audible signals, and for supplying the audible signals through said acoustical stems to a listener'"'"'s ears.
