Abstract

The present invention provides an emergency vision apparatus, comprising a blower; an inflatable enclosure remote from the blower, the enclosure being made of airtight material and having an expanded form when deployed and a deflated form when not in use; first and second clear members disposed at respective first and second ends of the enclosure to enable a user to see through the enclosure when expanded and observe a source of information at a distal end of the enclosure while smoke or other particulate matter is in the environment; a switch operably associated with the blower to activate the blower and thereby inflate the enclosure when deployed; and an air passageway connecting the blower and the enclosure, the passageway being extendible from a shorter length to a longer length when the enclosure is deployed.

Claims

1. An emergency vision apparatus, comprising:

a) a blower;

b) an inflatable enclosure remote from said blower, said enclosure being made of airtight material and having an expanded form when deployed and a deflated form when not in use;

c) first and second clear members disposed at respective first and second ends of said enclosure to enable a user to see through said enclosure when expanded and observe a source of information at a distal end of said enclosure while smoke or other particulate matter is in the environment;

d) a switch operably associated with said blower to activate said blower and thereby inflate said enclosure when deployed;

e) a tubular air passageway connecting said blower and said enclosure, said passageway being extendible from a shorter length for stowage to a longer length when said enclosure is deployed;

f) said passageway including an inner hose operably associated with an outer hose, said inner hose being disposed within said outer hose when said enclosure is not in use; and

g) said inner hose is slidable within and extendible from said outer hose when said enclosure is deployed.

2. An emergency vision apparatus as in claim 1, and further comprising:

a) a housing;

b) said inflatable enclosure when in said deflated form is disposed within said housing; and

c) said switch is attached to said housing.

3. An emergency vision apparatus as in claim 2, wherein:

a) said switch includes a lever between a depressed position wherein said switch is off and a released position wherein said switch is on; and

b) a removable member pressing on said lever in said depressed position and releasing said lever to said released position when said removable member is removed.

4. An emergency vision apparatus as in claim 3, wherein said removable member is operably attached to said enclosure.

5. An emergency vision apparatus as in claim 3, wherein:

a) said inner hose is attached to said enclosure; and

b) said removable member is attached to said inner hose.

6. An emergency vision apparatus as in claim 1, and further comprising:

a) a housing;

b) said enclosure when in said deflated form is disposed in said housing; and

c) said switch is activated automatically when said enclosure is taken out of said housing for deployment.

7. An emergency vision apparatus as in claim 1, wherein said passageway is extendible from a shorter length to a longer length as said enclosure is pulled out of said housing.

8. An emergency vision apparatus as in claim 1, wherein said passageway is telescoping.

9. An emergency vision apparatus as in claim 1, wherein said inner hose is attached to said enclosure.

10. An emergency vision apparatus as in claim 1, and further comprising:

a) a first housing for said blower and a second housing for said enclosure; and

b) one end of said outer hose is attached to said first housing and another end of said housing is attached to said second housing.

11. An emergency vision apparatus as in claim 1, and further comprising:

a) a housing having a vertically disposed side with an opening;

b) said blower is disposed within said housing, said blower having an inlet; and

c) said opening is operably associated with said inlet.

12. An emergency vision apparatus as in claim 1, and further comprising:

a) a housing having a top opening;

b) said enclosure when in said deflated form is disposed within said housing; and

c) a removable cover for said top opening.

13. An emergency vision apparatus, comprising:

a) first and second housings disposed remote from each other;

b) blower disposed in said first housing;

c) an inflatable enclosure disposed in said second housing when stowed, said enclosure being made of airtight material and having an expanded form when deployed and a deflated form when not in use, said enclosure being disposed in said second housing when in said deflated form;

d) first and second clear members disposed at respective first and second ends of said enclosure to enable a user to see through said enclosure when in said expanded form and observe a source of information at a distal end of said enclosure while smoke or other particulate matter is in the environment;

e) a switch operably associated with said blower to activate said blower and thereby inflate said enclosure when deployed;

f) an outer hose having one end connected to said first housing and in communication with said blower, said outer hose having another end connected to said second housing; and

g) an inner hose operably associated with said outer hose, said inner hose being disposed within said outer hose when said enclosure is disposed within said second housing, said inner hose having one end connected to and communicating with said enclosure, said inner hose extending from said second housing and telescoping from said outer hose when said enclosure is pulled out of said second housing.

14. An emergency vision apparatus as in claim 13, wherein:

a) said switch includes a lever between a depressed position wherein said switch is off and a released position wherein said switch is on; and

b) a removable member pressing on said lever in said depressed position and releasing said lever to said released position when said removable member is removed.

15. An emergency vision apparatus as in claim 14, wherein said removable member is operably attached to said enclosure such that said member is pulled out as said enclosure is taken of said second housing.

16. An emergency vision apparatus as in claim 14, wherein a tie is secured to said member and said inner hose.

17. An emergency vision apparatus as in claim 13, and further comprising a bypass switch for said blower.

18. An emergency vision apparatus as in claim 17, wherein:

a) said second housing includes a top opening; and

b) said bypass switch is operable through said top opening.

19. An emergency vision apparatus as in claim 13, wherein:

a) said second housing includes a top opening; and

b) a cover removably secured to said top opening.

20. An emergency vision apparatus as in claim 13, wherein said switch is automatically activated when said enclosure is taken out of said housing for deployment.

21. An emergency vision apparatus as in claim 13, wherein:

a) another inner hose is slidably disposed within said outer hose; and

b) said another inner hose is connected to said blower.
