Abstract

A display housing for a head mounted image display apparatus, said display housing being configured to be mounted to the head of a user with a pair of optical visual units adapted to present a virtual image to the user and a pair of earphones for providing sound to the user, each of the earphones attached to a respective side of the housing via a respective wire. The display housing comprises a linear wire retraction assembly situated thereacross, the wire retraction assembly configured to control the amount that a respective wire is pulled from the housing to allow each earphone to be selectably movable between a first, retracted state and a second, extended state.

Claims

1. A head mounted image display apparatus, comprising:

a display housing configured to be mounted to the head of a user, said display housing comprising a pair of optical visual units adapted to present a virtual image to the user from an image display device;

a pair of earphones for providing sound to the user, wherein each of said earphones is attached to a respective side of said housing via a respective wire; and

a wire retraction assembly having a linear configuration and being situated within and across said housing, said wire retraction assembly configured to control the amount that a respective wire is pulled from said housing to allow each earphone to be selectably movable between a first, retracted state and a second, extended state.

2. The display apparatus according to claim 1, wherein each of said pair of earphones may be mounted to a respective side of said display housing on an outside thereof when in said first, retracted state.

3. The display apparatus according to claim 2, wherein the outside of said display housing comprises a recess on each side thereof to accommodate said mounted pair of earphones when in said first, retracted state.

4. The display apparatus according to claim 1, wherein each of said pair of earphones may be moved away from said display housing so as to be inserted into a respective ear of the user when in said second, extended state.

5. The display apparatus according to claim 1, wherein said wire retraction assembly comprises a linear housing that is situated across said display housing.

6. The display apparatus according to claim 1, wherein said wire retraction assembly housing contains, for each earphone, a pulley configured to move along said wire retraction assembly housing between a distal end and a proximal end, wherein the respective wire of said earphone is looped around said pulley.

7. The display apparatus according to claim 6, wherein said pulley is rotatably mounted to a pulley mount, wherein said pulley mount is configured to move linearly along said wire retraction assembly housing from a distal end to a proximal end as pulling force is applied to the respective earphone wire looped around said pulley.

8. The display apparatus according to claim 7, further comprising an elastic member that biases said pulley mount towards said distal end of said wire retraction assembly housing, such that, when said pulling force is removed from the respective earphone wire, said pulley is biased towards said distal end of said wire retraction assembly by a biasing force.

9. The display apparatus according to claim 8, wherein said elastic member is attached between said pulley mount and said distal end of said wire retraction assembly housing, so as to bias said pulley mount towards said distal end of said wire retraction assembly housing by tensile force of said elastic member.

10. The display apparatus according to claim 8, wherein said elastic member is attached between said pulley mount and said proximal end of said wire retraction assembly housing, so as to bias said pulley mount towards said distal end of said wire retraction assembly housing by spring force of said elastic member.

11. The display apparatus according to claim 7, wherein said wire retraction assembly housing further comprises, for each earphone, a linear track extending from said proximal end to said distal end, and said pulley mount comprises a tracking member to allow said pulley mount to move linearly along said track within said wire retraction assembly housing, as pulling force is applied to the respective earphone wire and as said biasing force is applied by said elastic member.

12. The display apparatus according to claim 11, wherein said tracking member is a protrusion on a back side of said pulley mount that cooperates with said track to allow said pulley mount to move linearly therealong.

13. The display apparatus according to claim 11, wherein said tracking member is placed between, and is freely rotatable relative to, both a back side of said pulley mount and said linear track to allow said pulley mount to move linearly along said track.

14. The display apparatus according to claim 13, wherein said tracking member is spherically shaped.

15. The display apparatus according to claim 11, wherein said linear track further comprises an angled or backward releasable portion configured to allow said tracking member to move into said releasable portion, whereby said pulley mount remains near said proximal end of said wire retraction assembly housing despite the biasing force applied by said elastic member exceeding said pulling force applied to the respective earphone wire.

16. The display apparatus according to claim 15, wherein said tracking member may move out of said releasable catch portion by further pulling force applied to the respective earphone wire.

17. A display housing for a head mounted image display apparatus, wherein said display housing is configured to be mounted to the head of a user with a pair of optical visual units adapted to present a virtual image to the user and a pair of earphones for providing sound to the user, each of said earphones attached to a respective side of said housing via a respective wire, the display housing comprising:

a linear wire retraction assembly situated thereacross, said wire retraction assembly configured to control the amount that a respective wire is pulled from said housing to allow each earphone to be selectably movable between a first, retracted state and a second, extended state.

18. The display housing according to claim 17, further comprising a recess on a respective side thereof to allow each of said pair of earphones to be mounted thereagainst when in said first, retracted state, wherein said earphone may be removed therefrom so as to be inserted into a respective ear of the user when in said second, extended state.

19. The display apparatus according to claim 17, wherein said wire retraction assembly contains, for each earphone, a pulley rotatably mounted to a pulley mount that is configured to move linearly therealong between a first, distal end and a second, proximal end, wherein the respective wire of said earphone is looped around said pulley and exerts a pulling force on said pulley mount towards said second, proximal end.

20. The display apparatus according to claim 19, further comprising an elastic member that exerts a biasing force on said pulley mount towards said first, distal end.
