BACKGROUND
Field of the Invention
The present invention relates generally to a stereoscopic image viewer.
Related Art
Stereoscopy creates the illusion of three-dimensional depth from two-dimensional images. Stereoscopies is a technique for creating or enhancing the illusion of depth in an image by means presenting two offset images separately to the left and right eye of the viewer. These two-dimensional images are then combined by the brain to give the perception of three-dimensional depth. Virtual reality head mounted displays have been proposed in which a pair of displays and a pair of lenses are carried by headset goggles. Simpler viewers have been proposed which utilize a viewer's existing cell phone for the display. For example, see the Google Cardboard, and the Google Tech Go4d C1-glass.

Description
The present invention provides a stereoscopic image viewer system in which a frame with a pair of lenses is coupled with a handheld electronic device, such as a cellular phone. The frame can have a faceplate and a pair of side arms that can fold flat against the faceplate for efficiency in shipping and storage. The side arms can be identical, for efficiency in manufacturing and assembly. In addition, the entire frame, including the lenses, can be formed of made entirely of injection molded polypropylene plastic. The side arms have flexible fingers that form a pair of slots to hold the cellular phone. The design of the frame is open so that it can fit any size cellular phone. (In addition, the open design can reduce claustrophobic effect and motion sickness.) The side arms have a flexing region in the plastic, which allows cellular phones of any thickness (for example, up to 15 mm) to slip into the slots, and which will hold the cellular phone tightly. In addition, the flexible fingers can have a co-molded rubber section on the fingers to grip the cellular phone so that it does not slip or slide out of the slots. The side arms are connected to the faceplate by hinges that include two flexing regions that allows the plastic to flex and snap into holes. The side arms have flat area on the top and bottom edges for the user to easily grip the frame with their hands. In addition, the frame can have lenses that can twist-to-lock. Furthermore, the frame can have a forehead pad on the faceplate that abuts to the user's forehead. The forehead pad can comprise a polyurethane dome label for branding and promotional products purposes.
The system and frame can be utilized with the Google Cardboard ecosystem of virtual reality viewers and apps. The frame will allow viewer to put a cellular phone in the frame, load a virtual reality app on the cellular phone, and experience virtual reality environments, games, simulations, etc., similar to other much more expensive virtual reality headsets with built-in screens. Google has created an open source manufacturing plan for the boxy cardboard version of these viewers, which is what most manufacturers follow. The present frame is injection-molded plastic viewer that is compatible with this system. The viewer/user puts their cellular phone into the slots created by the flexible side arms, which grips the cellular phone tightly, and then the viewer/user can look through the lenses at the phone screen. The virtual reality application creates a stereoscopic 3D effect, and the viewer/user can turn around in all directions to see different parts of the virtual reality scene. Although most viewers that are built for Google's “Works with Google Cardboard” program are cardboard, the present frame is formed of plastic.
As illustrated in FIGS. 1-22, a stereoscopic image viewer system, indicated generally at 10, in an example implementation in accordance with the invention is shown comprising an ocular frame device 14 in combination with a handheld electronic device 18 (such as a cellular phone) having a display screen 20. The frame 14 of the system 10 provides a simple, but quality, stereoscopic image viewer for use with an existing handheld electronic device 18 (such as a cellular phone). The frame can have a forehead pad that can double as a label for branding and promotional products purposes. In addition, the frame can have lenses that can twist-to-lock. In addition, the frame 14 can be injection molded, and can have interchangeable side arms that can be identical for ease of assembly. In addition, the frame 14 can have a snap-fit hinge between the side arms and a face plate for ease of assembly. Furthermore, the side arms can have co-molded rubber sections to grip the handheld electronic device.
As stated above, the frame 14 has a face plate 22 and a pair of side arms 26 that carry the handheld electronic device in a spared-apart relationship with respect to the face plate. The face plate 22 has a pair of lens sockets 30 and a nose indentation 34. The lens sockets 30 are spaced-apart to correspond to the spacing of a user's eyes. The nose indentation 34 extends inwardly into the face plate from a bottom of the face plate, and defines an upright orientation of the face plate. Thus, a user can hold the face plate to his or her face, with the sockets aligning with his or her eyes, and his or her nose received in the nose indentation. The face plate can be formed of plastic by injection molding. The face plate can have a front, which can face the user's face during use. The sockets can have an axis, or axial direction, defined through the face plate and perpendicular to the face plate, or front thereof.
A pair of lenses 38 is carried in the pair of lens sockets 30 of the face plate. The lenses 38 (FIGS. 15-17) can be transparent and can have opposite convex surfaces. The lenses 38 can be formed of plastic by injection molding. The frame 14 carries the lenses 38 and the handheld electronic device 18, and maintains the lenses 38 and the screen 20 of the handheld electronic device in a spaced-apart relationship so that the user can view the screen through the lenses.
Each of the pair of sockets 30 and each of the pair of lenses 38 can have a twist-to-lock coupling securing each lens in a respective or corresponding socket. The lenses 38 can have tabs 42 extending radially from a perimeter of the lens, and spaced-apart around a circumference of the lens. In one aspect, the lens can have three tabs. Similarly, the sockets 30 can have notches 46 extending radially into a perimeter of the socket, and also extending axially into the faceplate (such as from a front of the face plate), and also spaced-apart around a circumference of the socket. Thus, the notches 46 of the socket 30 and the tabs 42 of the lens 38 correspond to one another, and can be aligned with one another.
Each notch 46 has a floor 50 facing axially with respect to the socket. The sockets 30 also have undercuts 54 extending circumferentially from the notches 46. Each notch 46 has a ceiling 58 formed by the undercut that faces opposite the floor 50. The ceiling 58 and the floor 50 can be circumferentially off-set with respect to one another, such as to accommodate formation by injection molding. The tabs 42 can have a width (or circumferential length) that spans between both the ceiling 58 and the floor 50. A lens is placed or inserted axially into each socket with the tabs disposed in the notches, and then twisted or turned radially (about 10 degrees) to lock the lens into place in the face plate. The lenses are held in place by the ceiling and floor. No other fasteners are needed. In one aspect, the socket or notch can have a ramp down to the floor in the notch, or from an outer surface of the face plate to the floor, or to a platform slightly raise with respect to the floor. The platform can lock the tab into place. As the lens is rotated underneath the ceiling, the tab drops from the platform into the lower floor. There can be a tight clearance between the platform and the ceiling, tighter than between the floor and the ceiling, so the lenses are maintained floating between the floor (holding back side of tab) and the ceiling (holding front side of tab).
The pair of side arms 26 are pivotally coupled to the face plate 22 by a pair of hinges 62. The side arms 26 have proximal ends pivotally connected to the face plate 22, and extend to opposite distal ends. Thus, the side arms 26 can pivot between an open, extended and/or use orientation (as shown in FIGS. 1-8), and a closed, retracted, and/or folded position (as shown in FIGS. 18a-22). The foldable side arms allow the side arms to fold against the face plate 22 for compact storage. The pair of hinges 62 each have an axel 66 (FIG. 14) segmented into opposite sides of the axel, and defining a pair of knobs 66a and 66b. A pair of flexible tabs 70 extend transverse to the axel, and carry the pair of knobs. The knobs are displaceable towards and away from one another (and thus the axel is collapsible upon itself to lengthen and shorten) by the flexion of the pair of flexible tabs. In addition, the pair of hinges each have a pair of bores 74 (FIG. 9) opposing one another, aligned with one another, and spaced-apart from one another. The pair of bores receive the pair of knobs, respectively, so that the pair of knobs (and the axel) pivot in the pair of bores as the side arms pivot with respect to the face plate. The pair of knobs are displaceable towards one another (to shorten the axel) to be received within, or inserted between, the pair of bores, and then displace away from one another (to lengthen the axel) to be retained within the bores.
In one aspect, the pair of bores 74 can be carried by the face plate 22, and are disposed in a pair of spaced-apart shoulders 78 and opposing one another and facing a notch 82 defined between the pair of shoulders. The pair of shoulders 78 can extend rearward from the face plate. The pair of flexible tabs 70 can extend from the proximal ends of the pair of side arms 26 with the knobs facing away from one another and displacable inwardly towards one another about the flexible tabs to be received in the notch 82 between the pair of shoulders 78. The pair of tabs 70 can be elastic and biased outwardly to maintain the pair of knobs 66a and 66b in the pair of bores. In another aspect, the shoulders 78 can have an outer wall 80 with an inner corner 80a that is arcuate and an outer corner 80b that is flat or pointed, as shown in FIG. 6. Thus, the side arms 26 can pivot in towards the face plate 22 about the curved inner corner 80a to retract to the storage orientation, and abut to the flat or pointed outer corner 80b in the open, extended and/or use configuration to maintain the side arms perpendicular to the face plate. Thus, the shape of the outer all of the shoulders allows the side arms to pivot 90 degrees, from an angle flat with the front plate, to 90 degrees perpendicular to the front plate. In addition, the side arms 26 have a length that is half or less than the width of the face plate so that both side arms can close towards one another over the face plate without overlapping.
As described above, the side arms 26 carry the handheld electronic device 18, and have proximal and distal ends. The distal ends of the pair of side arms 26 have flexible fingers 86 oriented upright with respect to the face plate 22, and defining a pair of slots 90 oriented upright between the flexible fingers and the pair of side arms to removably receive the handheld electronic device, as shown in FIGS. 3a and 3b. The flexible fingers 86 have proximal ends 94 connected to the pair of side arms and extending to distal free ends 98. The distal free ends 98 of the pair of flexible fingers 86 are movable towards and away from the pair of side arms to narrow and widen, respectively, the pair of slots 90. The flexible fingers 86 are elastic and biased towards the pair of side arms to pinch the handheld electronic device 18 in the slots 90, as shown in FIG. 3b. The distal free ends 98 of the flexible fingers 86 extend substantially to tops of the pair of side arms 26, so that the tops of the side arms and the distal free ends 98 of the fingers 86 are at substantially the same elevational height to provide a secure grip on the handheld electronic device. The flexible fingers 86 can be thicker at the proximal and distal ends 94 and 98, and thinner at intermediate location defining flexible regions 102 about which the distal free ends move or pivot. The flexible fingers 86 can be serpentine, and can curve away from the pair of side arms 26 at the proximal ends 94 thereof, curve back towards the pair of side arms at an intermediate location defining a contact point 106, and curve away from the pair of side arms to the distal free ends 98. Thus, the serpentine shape of the fingers can create an enlarged opening to the slots 90 to facilitate insertion and removal of the handheld electronic device. In addition, the distal free ends 98 of the flexible fingers 86 can each have an interior section 110 facing inwardly towards the slot 90, and formed of a different material than the flexible fingers. In one aspect, the interior sections 110 can be co-molded rubber to better grip the handheld electronic device.
In one aspect, the pair of side arms 26 can be the same shape and size, and thus can be interchangeable between each side of the face plate 22. Each of the pair of side arms 26 can extend in a plane 114 (FIGS. 5 and 6) defined between the proximal and distal ends of the pair of side arms. And each of the pair of side arms 26 can be symmetrical about the plane 114. Thus, each opposite half of the side arm is a mirror image of the opposite half.
Furthermore, the frame 14 and/or the face plate 22 can have a forehead pad 120 on a forward surface of the face plate, opposite the pair of arms. The forehead pad 120 can abut to a user's forehead during use and can provide a softer material than the face plate. In addition, the forehead pad 120 can provide a label for branding and promotional products purposes. In one aspect, the forehead pad can include or can be a squat dome 122 formed of a different material than the face plate, such as polyurethane. The dome 122 can have a broad, flat shape with an outfacing surface with a flat and smooth center surrounded by a radius perimeter. In addition, the dome can have indicia, such as logo, indicative of or representing a business, a product, or both, carried thereby and visible to a viewer.
In one aspect, the outfacing surface of the dome can extend beyond an outer surface of the face plate, as shown in FIG. 12a. The face plate can have a recess 124 in an outer surface thereof, and the forehead pad 120 or dome 122 can be disposed in the recess. The forehead pad or dome can have a thickness greater than a depth of the recess so that the outfacing surface can extend beyond the outer surface of the face plate. In another aspect, the outfacing surface of the dome can be flush or level with an outer surface of the face plate, as shown in FIG. 12b. An adhesive film 28 (FIG. 11b) can adhere the forehead pad 120 and/or the polyurethane dome 122 to the face plate 22. In one aspect, the forehead pad 120 and/or the polyurethane dome 122 can be translucent or transparent, so that the surface of the face plate can be visible through the dome. In another aspect, a graphic layer 132 (FIG. 11b) can be disposed between the face plate 22 and the polyurethane dome, and visible through the polyurethane dome.
As stated above, in one aspect, the dome 122 can be a polyurethane dome. The dome can 122 include the adhesive film 128 adhered to the surface of the face plate 22. The adhesive film can use a chemical adhesive to adhere. The adhesive can be selected to provide sufficient adhesion between the dome and face plate without separating as the frame is repeatedly used, such as insertion and removable from a case or pocket. The adhesive can also be selected so that the dome can be removed if desired. Thus, the adhesive film can include a releasable adhesive, as opposed to a permanent adhesive. The adhesive film can be a repositionable adhesive film releasable and repositionably adhered to the face plate. The adhesive film can have an adhesive bond between the dome and the face plate. The adhesive film also has a contact surface between the adhesive film or dome and the face plate. Furthermore, the adhesive and/or the adhesive film can be substantially transparent, or at least translucent, so that the surface of the face plate can be visible through the dome. The adhesive and/or adhesive layer can be a removable 3M ControltacTM adhesive.
The adhesive film 128 can be disposed on a substrate. The substrate can also be a film. In one aspect, the substrate can be substantially non-absorbent. The substrate can provide a surface, such as an upper or inner surface opposite the adhesive that can be printable. In addition, the substrate can be substantially transparent, or at least translucent, so that the surface of the face plate can be visible through the dome, and the substrate. The substrate can be a printed 3M® graphics vinyl. Alternatively, the substrate can be a polyester film. The substrate can be any laminated (non-porous) substrate, including: polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), acrylonitrile-butadiene-styrene (ABS), polyester, regular sticker paper, vinyl, or tin metal (foil). Alternatively, the substrate can have be other films with other characteristics, such as reflective, metal shine, textured, etc.
The dome 122 can be affixed to the adhesive film 128 and/or the substrate, and adhered to the face plate by the adhesive film. The dome 122 can be secured to the adhesive film and/or substrate. The dome can have a broad, flat, squat shape with an outfacing surface that faces and contacts the user's or viewer's forehead. The outfacing surface can be smooth and flat and parallel with the adhesive layer. In addition, the outfacing surface can be surrounded by a radius perimeter. Thus, the perimeter of the outfacing surface curves toward the adhesive layer and face plate. In one aspect, all of the outfacing surface can be flat and smooth and continuous between the radiused perimeter. The dome and/or outward facing surface can be tacky to cling to the user's forehead or another surface, such as by mechanical or specific adhesion. Furthermore, the dome can be substantially transparent, or at least translucent, so that the surface of the face plate can be visible through the dome.
The dome 122 or the outfacing surface thereof can provide a non-slip surface that can engage a user's forehead or a support surface. Thus, the outfacing surface can be sufficiently tacky to cling to the user's forehead, or other support surface, but sufficiently smooth or slippery to slid in and out of cases, pockets of clothing and clothing accessories. The tackiness of the outfacing surface can be obtained through various factors, which can include material, hardness/softness, and coefficient of friction. As described above, the dome can be formed of polyurethane. The polyurethane can be formed by combining a polyol with a catalyst or hardener. In one aspect, the ratio of polyol to catalyst can be between 1:0.63 to 0.85, so that there is more polyol than catalyst. In another aspect, the ratio of polyol to catalyst can be between 1:0.63 to 0.75. Typical polyurethane is obtained by mixing polyol and catalyst in a 1:1 ratio. In addition, in one aspect, the outfacing surface or dome can have a hardness between 10 and 35 Shore D. In another aspect, the outfacing surface or dome can have a hardness between 12 and 21 Shore D. In another aspect, the outfacing surface or dome can have a hardness between 12 and 18 Shore D. Other non-tacky stickers or decals typically can have a hardness of 60 Shore D or harder. Furthermore, the outfacing surface can have a coefficient of friction of between 0.3 and 0.1 in accordance with ASTM D 1894. Thus, the outwardly facing surface can be tacky to cling to the forehead, or other support surface, but smooth to facilitate insertion and removal from a pocket or purse.
A strength of the adhesive bond between the adhesive film and the face plate can be greater than a tacky cling between the outfacing surface of the dome and the forehead or other support surface. Thus, the dome remains on the face plate while the frame and dome are removed from the forehead or other support surface. In addition, the contact surface between the adhesive layer of the dome and the face plate can be greater than the outfacing surface of the dome contacting the forehead or other support surface to further retain the dome on the face plate as the frame and dome are removed from the forehead or other support surface. Furthermore, the contact surface between the adhesive layer of the dome and the face plate can have a perimeter greater than and circumscribing a perimeter of the outfacing surface of the dome that contacts the forehead or other support surface.
A graphic layer 132 can be disposed between the adhesive film 128 and the dome 122, or between the substrate and the dome. The graphic layer can include ink disposed on or printed on the substrate. For example, the graphic layer can be an aqueous based inkjet ink. The graphic layer can include indicia, such as a logo, a picture, etc. In addition, the graphic layer can include directions for use, orientation, care, etc. Furthermore, the graphic layer can be or can include other inclusions, as described in greater detail below. The graphic layer can be visible through the dome. The graphic layer and/or inclusion can be smaller or can have a smaller size than the substrate and dome such that the graphic layer and inclusion are surrounded by a perimeter of the dome and substrate. In one aspect, the graphic layer can include indicia that is indicative of a business, company or organization, such as a name, logo, slogan, trademark, service mark, etc. that is capable of identifying and/or distinguishing the business or company, or product or service, or both, or can otherwise be utilized to market, promote, and/or brand the business or company, or product or service, or both.
The dome can have a triangular shape with rounded corners, as shown. Alternatively, other shapes are possible, such as circular or scripted (i.e. shaped-like letters). In one aspect, the dome is smaller than the surface of the frame to which it is applied. In addition, the dome can have a thickness between 1-2 mm in one aspect, and 1.2-1.5 mm in another aspect. The thickness of the dome is dimensionally stable so that the dome is not generally compressible. The dome can have a stiffness with a self-supporting flat layer, yet can be flexible enough to be bent to conform to a curvature of the face plate or frame (if present). The adhesive layer can be sufficient to overcome the stiffness of the dome and maintain the curved or bent nature of the non-skid label when adhered to the face plate or frame (if curved). In addition, the dome can be elastic to return to its self-supporting flat layer. The dome and the outfacing surface can be substantially solid, flat, smooth and continuous.
As indicated above, the graphic layer can be or can include an inclusion. The inclusions can be embedded in the dome. For example, the graphic layer can be an etched metallic layer. The metallic layer can be etched to form the indicia. Other inclusions can be an LED (or other light source) and a battery power source; a hologram or lenticular artwork; an RFID computer chip or tag; a mirror; one or more gems or faux gems; etc. For example, an LED can be electrically coupled to a battery. The LED may remain continuously activated or lit. Alternatively, the LED may be activated, or the leads for the LED selectively contacted by the battery, such as by pressure applied to the non-skid label. Alternatively, a light sensor can be electrically coupled between the battery and the LED to activate the LED in low light conditions. Other electronics can be included for special effects, such as flashing, etc. It will be appreciated that multiple lights or LEDs of one or more color can be included or embedded in the dome. As another example, a gem or faux gem can be embedded in the dome. The inclusion(s) can be disposed on the adhesive film and/or substrate, and surrounded by the material of the dome so that the inclusion projects into the dome. Thus, the inclusions can be inclusions for the dome and/or the graphics layer.
The dome can also include inclusions embedded therein. For example, the dome can include a scented material, such as a scented oil, that is permeable through the polyurethane material of the dome. In addition, the dome can be colored and translucent. Furthermore, the dome can include a florescent material.
In another aspect, the dome can have an opaque dome with a graphic layer, such as printing, on the outfacing surface. The opaque dome can have a color to match or complement the frame.
As mentioned above, the dome can have any shape. In addition, the dome can be “scripted,” i.e. shaped as particular letters, symbols, etc.; which can be interconnected or can be one or more separate and discrete portions.
As discussed above, the dome or outfacing surface can have a radius perimeter. The dome can be made by pouring the polyurethane material on top of the substrate and graphic layer to form the dome. Thus, the radius perimeter is obtained by individual pouring each dome, without stamping or cutting the dome from a continuous layer. The graphic layer can be printed on the substrate having the adhesive film opposite the graphic layer. The graphic layer can be a discrete graphic contained within the pad or dome, as opposed to a continuous graphic.
While the forgoing examples are illustrative of the principles of the present invention in one or more particular applications, it will be apparent to those of ordinary skill in the art that numerous modifications in form, usage and details of implementation can be made without the exercise of inventive faculty, and without departing from the principles and concepts of the invention. Accordingly, it is not intended that the invention be limited, except as by the claims set forth below.
