Abstract

A drowsiness warning device includes a band which is securable about a wearer'"'"'s neck, and an alarm positioned by the band below the wearer'"'"'s chin for producing a tactile and an aural warning as the chin contacts the alarm device. The band includes a central section formed with a vertically stiff plastic material which is capable of holding a lower elongated body of the alarm therein. An upper rounded dome section of the alarm extends above the central section. The band also includes a pair of straps having hook and loop tape fasteners, and intermediate sections between the straps and the central section lined with a fibrous material for wearer comfort. In one embodiment, the alarm includes a hollow elastomeric ball having a mechanical noisemaker disposed within an air inlet/outlet aperture for the ball. In another embodiment, the alarm includes an electrically actuated speaker connectable to a battery on depression of the upper rounded dome.

Claims

1. A drowsiness warning device, comprising:

a band securable about a wearer'"'"'s neck; and

alarm means positioned by the band below a wearer'"'"'s chin, for producing an aural warning as the chin contacts the alarm means, wherein the alarm means includes an upper rounded dome extending above an upper edge of the band and positioned immediately below the chin, and a lower elongated body secured within the band.

2. The drowsiness warning device of claim 1, wherein the alarm means includes sound generation means therein activated by depressing the upper rounded dome with the chin.

3. The drowsiness warning device of claim 2, wherein the sound generation means comprises a hollow elastomeric ball, a portion of which forms the upper rounded dome, and a mechanical noisemaker disposed at least in part in a lower end of the ball.

4. The drowsiness warning device of claim 3, wherein the mechanical noisemaker comprises an air actuated flute means positioned adjacent to an air inlet/outlet aperture for the elastomeric ball.

5. The drowsiness warning device of claim 2, wherein the sound generation means comprises an electrically actuated speaker connectable to a battery on depression of the upper rounded dome.

6. The drowsiness warning device of claim 5, wherein the sound generation means includes a printed circuit board for controlling an audio signal to the speaker.

7. The drowsiness warning device of claim 5, wherein the upper dome includes a pair of upper contact plates, and the lower body includes a facing pair of lower contact plates, and wherein the alarm means includes spring means for urging the upper dome away from the lower body to space said upper plates from said lower plates in the absence of a counter-spring force applied by the chin to depress the upper dome and bring the upper and lower plates into contact.

8. The drowsiness warning device of claim 1, wherein the band includes central means for holding the lower body of the alarm means, and strap means at ends of the band and connectable to one another for securing the band about the wearer'"'"'s neck.

9. The drowsiness warning device of claim 8, wherein the strap means includes hook and loop tape fasteners.

10. The drowsiness warning device of claim 8, wherein the band means includes intermediate sections between the strap means and the central holding means, comprising a vertically stiff exteriorly facing support member, a fibrous interiorly facing lining adjacent to the support member, and upper and lower edge guards extending over, respectively, upper and lower edges of the support member and the adjacent lining.

11. The drowsiness warning device of claim 8, wherein the central holding means comprises a vertical wall having a pair of parallel, generally horizontally extending slots cut therein to define an upper front support segment, an intermediate rear support segment and a lower front support segment of the wall between which the lower elongated body of the alarm means is positioned.

12. The drowsiness warning device of claim 11, wherein the vertical wall further includes a lower support tab which engages a bottom end of the lower body of the alarm means to limit downward movement thereof relative to the vertical wall.

13. A drowsiness warning device, comprising:

a band including a central section, strap means at opposite ends of the band and connectable to one another for securing the band about a wearer'"'"'s neck, and intermediate sections between the strap means and the central section; and

alarm means positioned by the central section of the band below a wearer'"'"'s chin, for producing an aural warning as the chin contacts the alarm means, the alarm means including an upper rounded dome extending above an upper edge of the central section of the band and positioned immediately below the chin, a lower elongated body secured within the central section of the band, and sound generation means actuated by depressing the upper rounded dome with the chin.

14. The drowsiness warning device of claim 13, wherein the central section comprises a vertical wall having a pair of parallel, generally horizontally extending slots cut therein to define an upper front support segment, an intermediate rear support segment and a lower front support segment between which the lower elongated body of the alarm means is positioned, and a lower support tab which engages a bottom end of the lower body of the alarm means to limit downward movement thereof relative to the vertical wall.

15. The drowsiness warning device of claim 14, wherein the strap means includes hook and loop tape fasteners, and wherein the intermediate sections comprise a vertically stiff, exteriorly facing support member, a fibrous interiorly facing lining adjacent to the support member, and upper and lower edge guards extending over, respectively, upper and lower edges of the support member and the adjacent lining.

16. The drowsiness warning device of claim 13, wherein the sound generation means comprises a hollow elastomeric ball, a portion of which forms the upper rounded dome, and a mechanical noisemaker disposed at least in part in a lower end of the ball, the noisemaker comprising an air actuated flute means positioned adjacent to an air inlet/outlet aperture for the elastomeric ball.

17. The drowsiness warning device of claim 13, wherein the sound generation means comprises an electrically actuated speaker connectable to a battery on depression of the upper rounded dome, wherein the upper dome includes a pair of upper contact plates and the lower body includes a facing pair of lower contact plates, and wherein the alarm means includes spring means for urging the upper dome away from the lower body to space said upper plates from said lower plates in the absence of a counter-spring force applied by the chin to depress the upper dome and bring the upper and lower plates into contact.

18. A drowsiness warning device, comprising:

a band including a central section, strap means at opposite ends of the band and connectable to one another for securing the band about a wearer'"'"'s neck, and intermediate sections between the strap means and the central section;

alarm means positioned by the central section of the band below a wearer'"'"'s chin, for producing an aural warning as the chin contacts the alarm means, the alarm means including an upper rounded dome extending above an upper edge of the central section of the band and positioned immediately below the chin, a lower elongated body secured within the central section of the band, and sound generation means actuated by depressing the upper rounded dome with the chin, wherein the sound generation means comprises a hollow elastomeric ball, a portion of which forms the upper rounded dome, and a mechanical noisemaker disposed at least in part in a lower end of the ball, the noisemaker comprising an air actuated flute means positioned adjacent to an air inlet/outlet aperture for the elastomeric ball;

wherein the central section comprises a vertical wall having a pair of parallel, generally horizontally extending slots cut therein to define an upper front support segment, and intermediate rear support segment and a lower front support segment between which the lower elongated body of the alarm means is positioned, and a lower support tab which engages a bottom end of the lower portion of the alarm means to limit downward movement thereof relative to the vertical wall.

19. The drowsiness warning device of claim 18, wherein the strap means includes hook and loop tape fasteners, and wherein the intermediate sections comprise a vertically stiff, exteriorly facing support member, a fibrous interiorly facing lining adjacent to the support member, and upper and lower edge guards extending over, respectively, upper and lower edges of the support member and the adjacent lining.
