Abstract

A device that allows viewing of 3D and virtual reality that is displayed on a portable device such as a cell phone for example an iPhone or any such type known as a smartphone. The device has vertical and horizontal panels that are hinged together to fold flat and to unfold into a box shape. One end is an attachment frame that allows attaching of the display source device so that its screen can be seen through the open box from the other end. On the other end is a lens frame on which are a pair of spaced apart lens for viewing separately of each eye thereby allowing 3 D viewing. The device can be equipped with a sterol separator wall to prevent vision confusion. All the parts are hinged together so as to allow the entire device to fold into a generally flattened package.

Claims

1. A glare blocking viewfinder and virtual reality viewing device adapted to be detachably mounted on an image display device, said image display device being substantially flat and rectangular and having predetermined width and height dimensions and having an image display screen, said device comprising:

a one-piece box portion having opposite sides panels and opposite horizontal panels defining a top panel and a bottom panel, the side panels being joined at adjoining edges to the top and bottom panels by hinges to form a box that can be in an open position and folded to a collapsed position and in the open position forming a rectangular opening at opposite ends, the openings defining an attachment end and a viewing end and further comprising an attaching frame at the attachment end attached by a hinge to one of the panels and a viewing frame at the viewing end attached by a hinge to a panel that is opposite to the one on which the attaching frame is hinged;

a pair of spaced apart lenses mounted in or integral to the viewing frame;

an attachment mechanism on the attaching frame for attaching the image display device with the image display screen being viewable through the lenses;

whereby the device can be configured for use, as a viewfinder with the viewing frame and lenses in place over the viewing end and the attaching frame in place over the attaching end and as a glare reducing box with the viewing frame rotated up to 270 degrees into contact with the panel to which it is hinged and when viewing stereo imagery on an image display screen allowing 3 dimensional viewing and also having a storage configuration in which the box portion is collapsed and the attaching frame is folded into contact with the panel to which it is attached on one side of the folded box and the viewing frame and lenses are folded into contact with the panel to which it is attached on the other side of the folded box.

2. The device of claim 1 where the lenses have a magnifying power of 2×

to 5×

.

3. The device of claim 1 where the attachment mechanism comprises at least one elastic member extending across the attachment end.

4. The device of claim 1 where the attachment mechanism includes a magnet.

5. The device of claim 1 where the attachment mechanism comprises a hook and loop two-component fastener.

6. The device of claim 1 where the attachment mechanism comprises an open sleeve with opposed open sidewalls and opposed open ends, enabling the image display device to be inserted into the sleeve through one end and images thereon to be viewed through the device.

7. The device of claim 1 having a width dimension where the width dimension is sufficient to accommodate both eyes of a user viewing the image display screen at the same time.

8. The device of claim 7 where the width dimension is substantially from 3.5 to 5 inches.

9. The device of claim 1 wherein at least the box portion is one piece of molded plastic and the hinges are living hinges.

10. The device of claim 9 wherein the attaching frame and the viewing frame are also part of the one piece of molded plastic and are attached by living hinges.

11. The device of claim 1 wherein the two lenses each have an optical axis which define a spacing of the lenses and which are substantially parallel and substantially orthogonal to an image screen of an image display device attached to the attachment end.

12. The device of claim 1 wherein the two lenses are optical lenses.

13. The device of claim 1 wherein the two lenses are Fresnel lenses.

14. A combination of a virtual reality viewing device detachably mounted on an image display device, said image display device being substantially flat and rectangular and having predetermined width and height dimensions and having an image display screen, said device comprising:

a one-piece box portion having opposite sides panels and opposite horizontal panels defining a top panel and a bottom panel, the side panels being joined at adjoining edges to the top and bottom panels by hinges to form a box that can be in an open position and folded to a collapsed position and in the open position forming a box shape with rectangular opening at opposite ends, the openings defining an attachment end and a viewing end and further comprising an attaching frame at the attachment end attached by a hinge to one of the panels and a viewing frame at the viewing end attached by a hinge to a panel that is opposite to the one on which the attaching frame is hinged;

a pair of spaced apart lenses mounted in or integral to the viewing frame;

an attachment mechanism on the attaching frame for attaching the image display device with the image display screen being viewable through the lenses;

whereby the device can be configured for use when viewing stereo imagery on an image display screen allowing 3 dimensional viewing through the lenses and also having a storage configuration in which the box portion is collapsed and the attaching frame is folded into contact with the panel to which it is attached on one side of the folded box and the viewing frame and lenses are folded into contact with the panel to which it is attached on the other side of the folded box.

15. The device of claim 14 wherein the image display device is of hand held type able to receive imagery by one or more of wi-fi or internet or telephony connection.

16. The device of claim 14 wherein the two lenses each have an optical axis which define a spacing of the lenses and which are substantially parallel and substantially orthogonal to the image screen of the image display device.

17. The device of claim 14 wherein the two lenses are optical lenses.

18. The device of claim 14 wherein the two lenses are Fresnel lenses.

19. The device of claim 14 further comprising a stereo separator wall extending from proximate the viewing end toward the attachment end and terminating a distance range of approximately at least ¾

of the distance to the viewing end to all the way to the viewing end.

20. The device of claim 14 further comprising retaining means for retaining the device in the box shape.

21. The device of claim 14 further comprising retaining means at the attachment end to retain the attaching frame in position when the image display device is in place.
