Claims
- 1. An eye glass comprising:a) a headband configured to be secured to a user's head; b) a lens assembly rotatably connected to said headband and having an eye shield therein; and, c) a tensioning mechanism having, 1) a first pulley secured to said headband, 2) a second pulley secured to said lens assembly, and, 3) an elastic band being substantially oval and having a central support, said elastic band stretched between said first pulley and said second pulley such that said elastic band encourages selective rotation of said lens assembly relative to said headband to: a first resting state within a user's line of sight, and a second resting state outside the user's line of sight.
- 2. The eye glass according to claim 1, wherein said headband includes:a) a stiff head mount support adapted to be placed over a user's forehead, and, b) an elastic strap connected to said stiff head mount support and adapted to extend around a back of a user's head.
- 3. The eye glass according to claim 1, wherein said lens assembly is rotatably connected to said headband using a rivet mechanism.
- 4. The eye glass according to claim 3, wherein said lens assembly includes an armature secured to said rivet mechanism and said second pulley.
- 5. The eye glass according to claim 4, wherein said elastic band contacts only said first pulley and said second pulley.
- 6. The eye glass according to claim 5, wherein said elastic band is generally oval and includes a central support extending from side to side of said elastic band.
- 7. The eye glass according to claim 1, wherein said eye shield is detachable from said lens assembly.
- 8. The eye glass according to claim 7, further including a corrective vision lens connected to said eye shield.
- 9. The eye glass according to claim 8,a) wherein said eye shield includes a nose piece; and, b) wherein said corrective vision lens is secured to said nose piece.
- 10. The eye glass according to claim 9, wherein said corrective vision lens is removable from said eye shield.
- 11. The eye glass according to claim 8, wherein said corrective vision lens is positioned such that, when said eye glass is worn by a user, said corrective vision lens are positioned between the user and the eye shield.
- 12. An eye protective apparatus comprising:a) a headband configured to be secured to a user's head, said headband having a first pulley; b) a lens assembly rotatably connected to said headband and having an eye shield therein, said lens assembly having a second pulley secured thereto; and, c) an elastic band being substantially oval and having a central support, said elastic band stretched between said first pulley and said second pulley such that maximal relaxation of said elastic band occurs at a first state and a second state, said elastic ban, at all times, contacting only said first pulley and said second pulley.
- 13. The eye protective apparatus according to claim 12, wherein:a) said first state positions said eye shield within a user's line of sight; and, b) said second state positions said eye shield outside the user's line of sight.
- 14. The eye protective apparatus according to claim 13, wherein said eye shield is detachable from said lens assembly.
- 15. The eye protective apparatus according to claim 13, further including a corrective vision lens connected to said eye shield.
- 16. An eye glass comprising:a) a headband having, 1) a stiff head mount support adapted to be placed over a user's forehead, and 2) an elastic strap connected to said stiff head mount support and adapted to extend around a back of a user's head; b) a lens assembly rotatably connected to said headband and having a removable eye shield therein; and, c) a tensioning mechanism having, 1) a first pulley secured to said stiff head mount, 2) a second pulley secured to said lens assembly, and, 3) an elastic band being substantially oval and having a central support, said elastic band stretched between said first pulley and said second pulley such that said elastic band encourages selective rotation of said lens assembly relative to said headband to: a first resting state within a user's line of sight, and a second resting state outside the user's line of sight.
- 17. The eye glass according to claim 16,a) wherein said lens assembly includes an armature supporting said second pulley, said armature rotatably secured to said stiff head mount support via a rivet mechanism; b) wherein said elastic band is substantially oval in shape and contacts only said first pulley and said second pulley.
- 18. The eye glass according to claim 16, further including a corrective vision lens is connectable to said eye shield via a nose piece.
