COLLAPSIBLE VIRTUAL REALITY VIEWER ASSEMBLY

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

Not applicable.

TECHNICAL FIELD

The present invention generally relates to assemblies for viewing virtual reality displays. More specifically, the present invention relates to various embodiments of a collapsible virtual reality viewer.

BACKGROUND

There are currently applications for computing devices, such as smartphones, that are designed to provide a user with a virtual reality experience. To achieve the virtual reality experience, a user may view a virtual reality display on the device through a viewer. The viewer may have a slot for the device, and a user can look through viewing holes to see the virtual reality display on the device. Because viewers may be used with smartphones, which are easily transportable, a user may also wish to have a viewer that is also easily transportable. Traditional viewers, however, require assembly by the user and are designed to remain in the assembled form. These traditional viewers tends to be bulky and do not easily slip into a user's pocket or purse for transporting. A fully collapsible viewer that does not require any assembly is needed to provide more a more transportable and easy-to-use viewer. Additionally, a fully collapsible viewer made from a single piece of material, such as a blank of cardstock, provides a cost-efficient option and can easily be mailed as a flat item. Further, it may be desirable to integrate promotional material into a collapsible virtual reality viewer.

SUMMARY

DETAILED DESCRIPTION

In simplest terms, the present invention may be referred to as a “collapsible virtual reality viewer.” The viewer is designed to provide an easily transportable and economically manufactured headset for virtual reality viewing using a virtual reality application on a computing device, such as a smartphone. The viewer may be used when in an expanded configuration and may be collapsed to a closed configuration when not in use. In some embodiments, the viewer also includes promotional material, such as advertisements or coupons. Further, the viewer may be a unitary structure made from a single piece of material, such as cardstock. Various embodiments of the viewer are described below.

FIGS. 1, 2, and 3 provide a front perspective view, a rear perspective view, and a side elevation view, respectively, of a viewer 100 in an expanded configuration. In some embodiments, the viewer 100 is formed from a single piece of material that is die cut and folded to form a plurality of panels. It should be noted that the term “die cut” should be interpreted broadly to cover all types of cutting a desired shape out of a piece of material or stock (e.g. laser, scissors, pressing of dies, etc.). The material comprising the plurality of panels may be a variety of materials including plastics, natural paper, synthetic paper, and the like. In some embodiments, the panels comprise cardstock. Embodiments of the viewer 100 further comprise a plurality of fold lines between the panels that facilitate movement between the open and collapsed configurations. It should be noted that the term “fold line” as used in this disclosure should be interpreted broadly to cover all types of bends, scores, rules, creases, perforations, etc.

These panels may comprise a viewing portion 102 and a body portion 104 of the viewer 100. As illustrated in FIG. 1, the body portion 104 may at least partially enclose or surround the viewing portion 102 when the viewer 100 is in the expanded configuration. As such, the panels comprising the body portion 104 generally form the exterior of the viewer 100. Specifically, the body portion 104 may include a first body wall 112 and a second body wall 114 opposite the first body wall 112. The first body wall 112 may comprise a first body panel 122 while the second body wall 114 may comprise a second body panel 124 and a third body panel 128. The third body panel 128 may be coupled to the second body panel 124. For example, in some embodiments, at least a portion of the third body panel 128 is permanently secured to at least a portion of the second body panel 124 with a layer of adhesive. By permanently securing the third body panel 128 to the second body panel 124, the viewer 100, in a collapsed configuration, need only be expanded before it is ready for use. In this way, unnecessary assembly for the user is eliminated. It is contemplated, however, that the third body panel 128 may also be releasably coupled to the second body panel 124 with a releasable coupling mechanism such as a hook and loop fastener (e.g., Velcro®), snap-type fasteners, and the like.

The first body wall 112 and the second body wall 114 may be substantially parallel to one another. The first body wall 112 and the second body wall 114 may be joined at one end by a first side wall 106 and at an opposite end by a second side wall 108. The first side wall 106 may comprise a first side panel 132 and a second side panel 134, while the second side wall 108 may include a third side panel 136 and a fourth side panel 138. The first and second body panels 122 and 124, respectively, and the first, second, third, and fourth side panels 132, 134, 136, 138, respectively, generally form an outer perimeter of the body portion 104 of the viewer 100.

More specifically, at one end, the first side panel 132 may be adjacent the first body panel 122 at a first fold line 140 and adjacent the second side panel 134 at a second fold line 142 (sometimes described as the side panel fold line), while the second side panel 134 may be adjacent the second body panel 124 at a third fold line 144. Similarly, at the other end, the third side panel 136 may be adjacent the second body panel 124 at a fourth fold line 146 while the fourth side panel 138 may be adjacent the first body panel 122 at a fifth fold line 148. The third side panel 136 and the fourth side panel 138 may be coupled together via a side tab 150, rather than being directly coupled along a fold line. In some embodiments, the side tab 150 may abut the third side panel 136 at a side tab fold line 152 and may use a coupling mechanism to attach to the fourth side panel 138. For example, the side tab 150 may be permanently secured to the fourth side panel 138 by a layer of adhesive. In other embodiments, the side tab 150 may be adjacent the fourth side panel 138 at a fold line and attach to the third side panel 136 with a coupling mechanism. In alternative embodiments, however, the third side panel 136 and the fourth side panel 138 may directly abut a fold line while the side tab couples either the third side panel 136 to the second body panel 124 or the fourth side pane 132 to the first body panel 122.

As illustrated in FIG. 1, the first side panel 132 and the second side panel 134 may form a first angle 153 with respect to each other that is equal to a second angle 154 between the third side panel 136 and the fourth side panel 138. The first angle 153 and the second angle 154 may be determined by the shape of the panels of the viewing portion 102 that are positioned within the body portion 104. In the embodiments depicted, for instance, the panels of the viewing portion 102, which are discussed in greater detail with respect to FIGS. 6 and 7, have side walls adjacent to the first side wall 106 and the second side wall 108 of the body portion 104 that each form a viewing panel angle 155. In some embodiments, the first and second angles 153 and 154, respectively, are substantially equal to the viewing panel angle 155 when in an expanded configuration. In some embodiments, the first and second angles 153 and 154, respectively, are each less than 180 degrees. For example, the first and second angles 153 and 154, respectively, may each be approximately 115 degrees. In alternative embodiments, the first and second angles 153 and 154, respectively, may each be 180 degrees when in an expanded configuration such that the first side wall 106 is parallel to the second side wall 108. In these embodiments, the viewing panel angle 155 may also be 180 degrees.

In addition to the first and second side walls 106 and 108, respectively, the first body wall 112 and the second body wall 114 may be coupled by a back wall 116 comprising a back panel 126, as shown in FIGS. 2 and 3. The back panel 126 may be adjacent the first body panel 122 at a sixth fold line 156 and adjacent to the third body panel 128 at a seventh fold line 158. The back panel 126 may include a back panel fold line 130 that divides the back panel 126 into a top portion 126a and a bottom portion 126b. When in an expanded configuration, the back panel 126 may be perpendicular to both the first body panel 122 and the third body panel 128 as well as the second body panel 124. As depicted in FIG. 3, the back panel 126 may not be directly abutting the side panels 132, 134, 136, and 138 to provide a slot 160 for receiving a virtual reality display device. As used in this disclosure, a virtual reality display device includes any device having a display screen and capable of displaying a virtual reality display. An exemplary virtual reality display device is a smartphone. To provide for a slot for the virtual reality display device, the first body panel 122 may extend beyond the back edge 162 of the first side panel 132 and the back edge 168 (shown in FIG. 2) of the fourth side panel 138. The second body panel 124, on the other hand, may not extend as far as the first body panel 122 and, therefore, may not completely extend to the back panel 126. Accordingly, the third body panel 128 may bridge the gap between the back panel 126 and the second body panel 124 to form a lower surface for a virtual reality display device received in the slot 160. FIG. 4 depicts a front perspective view of the viewer 100 with a virtual reality display device 194 being inserted into the slot 160 formed by the viewer 100.

As can be seen in FIGS. 1-4, one or more additional side panels may be positioned over and secured to the first side panel 132. FIG. 5, for example, provides a partially exploded view of the viewer 100 to show a fifth side panel 180 and a sixth side panel 186 layered on top of the first side panel 132. The fifth side panel 180 and the sixth side panel 186 may each have the same general shape as the first side panel 132. When put together, the sixth side panel 186 may overlay and be coupled to the fifth side panel 180, which may overlay and be coupled to the first side panel 132. For example, in some embodiments, an exterior surface 178 of the first side panel 132 may be permanently secured to an interior surface 182 of the fifth side panel 180 with a layer of adhesive while an exterior surface 184 of the fifth side panel 180 may be permanently secured to an interior surface 188 of the sixth side panel 186 with a layer of adhesive. The fifth side panel 180 and the sixth side panel 186 may each include an opening through which a portion of the exterior surface 178 of the first side panel 132 is visible, as shown in FIGS. 1 and 3. For example, the fifth side panel 180 has a first opening 190, and the sixth side panel 186 has a second opening 192. When the sixth side panel 186 is secured to the fifth side panel 180, the first opening 190 may be aligned with the second opening 192. In the embodiment illustrated, the first opening 190 and the second opening 192 each comprises an oval shape, but it is contemplated that the opening may include other shapes, such as a circular shape or polygon shape.

The first and second openings 190 and 192, respectively, may cooperate to form a shallow slot for holding a magnet or another object having magnetic properties, such as a coin or washer. A user may move the magnet on the exterior surface 178 of the first side panel 132 within the confines of the first and second openings 190 and 192, respectively, to interact with a virtual reality display device that is inserted into the slot 160. For example, smartphones having a magnetometer or similar technology may sense the movement of the magnet as if the user is physically touching the display screen of the smartphone. In this way, the user can control the virtual reality display on the virtual reality display device without having direct physical contact with the device. The first and second openings 190 and 192 may be positioned off center of their respective panels so that they are closer to the slot 160 than to the front of the viewer 100. In some embodiments, a magnet is integrated with the viewer 100. In other embodiments, the magnet is a separate piece.

Though the view of FIG. 5 depicts the fifth side panel 180 and the sixth side panel 186 as discrete panels separate from other panels of the body portion 104, the fifth side panel 180 and the sixth side panel 186 may be formed of the same die-cut blank as the first side panel 132, which is described further with respect to FIG. 17. Additionally, some embodiments may include only the fifth side panel 180 and not the sixth side panel 186.

All together, the walls of the body portion 104 of the viewer 100 cooperate to form and define an inner cavity within which the viewing portion 102 may be at least partially disposed. Front perspective and rear perspective views of the viewing portion 102 with the body portion 104 shown in dashed lines are provided in FIGS. 6 and 7. The viewing portion 102 may include an inner viewing panel 210, an intermediate viewing panel 220, and an outer viewing panel 230. One or more panels of the viewing portion 102 may be coupled to the body portion 104. In exemplary embodiments, for example, the inner viewing panel 210 is coupled to the second body panel 124 at an eighth fold line 222, which is further illustrated in FIGS. 17 and 18, while the outer viewing panel 230 is coupled to the second body panel 124 by one or more viewing panel tabs 234. In the embodiment illustrated, there are two viewing panel tabs 234, each adjacent a bottom edge of the outer viewing panel 230 at a viewing tab fold line 236. In an alternative embodiment, there is a single viewing panel tab 234 extending across the bottom edge of the outer viewing panel 230. The viewing panel tabs 234 may be permanently or releasably coupled to at least a portion of the second body panel 124. In some embodiments, for example, the viewing panel tabs 234 are permanently secured to the second body panel 124 via a layer of adhesive.

When the viewer 100 is in the expanded configuration, the inner viewing panel 210 and the outer viewing panel 230 are substantially parallel to each other as well as substantially parallel to the back panel 126 of the body portion 104. The inner viewing panel 210 may be positioned between the back panel 126 and the outer viewing panel 230. The inner viewing panel 210 cooperates with at least a portion of the first body panel 122, a portion of the third body panel 128 and the back panel 126 to form a slot for the virtual reality display device.

The inner viewing panel 210 and the outer viewing panel 230 may be coupled by the intermediate viewing panel 220. Specifically, the intermediate viewing panel 220 may be adjacent the inner viewing panel 210 at a ninth fold line 224 and adjacent the outer viewing panel 230 at a tenth fold line 226. When the viewer 100 is in a use position or expanded configuration, as illustrated in FIGS. 1-7, the intermediate viewing panel 220 is generally perpendicular to the inner viewing panel 210 and the outer viewing panel 230. Additionally, the intermediate viewing panel 220 is positioned underneath of and is parallel to the first body panel 122 of the body portion 104.

When in the expanded configuration, the viewer 100 is designed to allow a user to see a virtual reality display on a virtual reality display device that has been inserted into the slot 160. As such, the inner viewing panel 210 and the outer viewing panel 230 may include one or more apertures through which a user can see the virtual reality display. For example, the inner viewing panel 210 may include a display aperture 216. The display aperture 216 illustrated is the same shape of the inner viewing panel 210 and extends almost to the edges of the inner viewing panel 210. In this way, the inner viewing panel 210 provides a thin frame around the display aperture 216. The display aperture 216 may be of any desired shape. Some embodiments include a reinforcement panel identical to the inner viewing panel 210. The reinforcement panel may overlay and be secured to the inner viewing panel 210 to increase the strength of the inner viewing panel 210 around the display aperture 216.

Additionally, the outer viewing panel 230 may include one or more viewing apertures 238 that provide a user with a view of the inside of the viewer 100 to see the virtual reality display. For instance, the outer viewing panel 230 may include two circular viewing apertures 238 positioned on the outer viewing panel 230 to align with a user's eyes when the first body panel 122 is positioned against a user's forehead. Accordingly, a user may position the viewer 100 against the user's head so that each eye can see through a viewing aperture 238 in the outer viewing panel 230 and through the display aperture 216 in the inner viewing panel 210 to see a virtual realty display on a virtual reality display device inserted into the slot 160. In some embodiments, the viewer 100 includes a lens in each of the viewing apertures 238.

As the viewer 100 is designed to be used when placed up against a user's face, exemplary embodiments are adapted to fit around the user's face. For example, the front edges of the first body panel 122 and the second body panel 124 may be curved inward to accommodate the curvature of a user's face. Additionally, the outer viewing panel 230 may include a slit 240 running vertically in between the viewing apertures 238 from the bottom edge of the outer viewing panel 230 along a midline of the outer viewing panel 230. The outer viewing panel 230 may also include two curved fold lines 242 running from the top of the slit 240 to the bottom edge of the outer viewing panel 230 on each side of the slit 240. The slit 240 and the two curved fold lines 242 allow the outer viewing panel 230 to slightly open up to accommodate a user's nose when viewing a virtual reality display through the viewing apertures 238.

When not being used in the expanded configuration to view a virtual reality display, a user may fold the viewer 100 into the collapsed configuration. FIGS. 8 and 9 provide a front perspective view and a rear perspective view, respectively, of the viewer 100 in a partially collapsed configuration. As the viewer 100 is moved into the collapsed configuration, the back panel 126 may fold at its back panel fold line 130 such that the top portion 126a of the back panel 126 moves closer to the bottom portion 126b of the back panel 126. The first side panel 132 and the second side panel 134 may fold at the second fold line 142 to move toward each other. Likewise, the third side panel 136 and the fourth side panel 138 with the attached side tab 150 fold at the side tab fold line 152 so that the first side panel 132 moves closer to the fourth side panel 138 and the side tab 150. As the side panels 132, 134, 136, and 138 are folded inwards, the first angle 153 and the second angle 154 decreases. At the same time, the first body panel 122 is moved closer to the second body panel 124 and the third body panel 128.

To allow the body portion 104 to collapse, the viewing portion 102 disposed within the cavity of the body portion 104 also collapses. Specifically, the intermediate viewing panel 220 slides forward to move out from underneath the first body panel 122, allowing the first body panel 122 to be moved closer to the second body panel 124 and the third body panel 128. The intermediate viewing panel 220 folds inward at the tenth fold line 226 towards the outer viewing panel 230 while, at the same time, folds outward at the ninth fold line 224 away from the inner viewing panel 210. Additionally, the inner viewing panel 210 and the second body panel 124 fold towards each other at the eighth fold line 222.

FIGS. 10-13 illustrate various views of the viewer 100 when in a fully collapsed configuration. In this configuration, a top surface 244 of the viewer 100, shown in FIGS. 10 and 11, comprises the sixth panel 186 that is secured to the fifth side panel (not shown) and the first side panel 132, the first body panel 122, and the fourth side panel 138 with the side tab 150 secured to a portion of the fourth side panel 138. The bottom surface 246 of the viewer 100 in a collapsed configuration, shown in FIGS. 12 and 13, comprises the second side panel 134, the second body panel 124 with the third body panel 128 secured to second body panel 124, and the third side panel 136. The back panel 126, which may be folded in half along the back panel fold line 130, and the inner viewing panel 210 may be sandwiched between the first body panel 122 and the second body panel 124. The intermediate viewing panel 220 and at least a portion of the outer viewing panel 230 may be visible and sticking out between the top surface 244 and the bottom surface 246. The viewer 100 may move from the collapsed configuration to an expanded configuration when a user pushes together the second fold line 142 and the side tab fold line 152.

When in the collapsed configuration, the viewer 100 may be relatively flat. For example, when in a fully collapsed configuration, the viewer 100 may have a thickness between the top surface 244 and the bottom surface may be less than one-fourth of an inch in some embodiments. The ability of the viewer 100 to be placed in a collapsed position to have a thin profile may be desirable when using the viewer 100 for promotional purposes. For example, the viewer 100 with promotional material, such as advertisements, may be handed out by businesses or mailed to potential customers.

Embodiments of the viewer 100 with promotional materials are depicted in FIGS. 14-16. In these embodiments, the viewer 100 may include a detachable portion 250. The detachable portion 250 may include a detachable panel 252 coupled to the third body panel 128 at a fold line. In some embodiments, such as the one illustrated in FIG. 16, this fold line is a plurality of perforations 254. The plurality of perforations 254 may be the only mechanism attaching the detachable panel 252 to the rest of the viewer. Accordingly, the detachable panel 252 may be completely detachable from the rest of the viewer 100 along the plurality of perforations 254. The detachable panel 252 may include printed promotional material, such as an advertisement, a coupon, or business information, printed on the detachable panel 252. The detachable panel 252 may also include a mailing address such that the viewer 100 can be used as a mailer. The printed promotional material may be printed directly on the detachable panel 252 or secured to the detachable panel 252, for example, by an adhesive. In some instances, the promotional material is removeably coupled to the detachable panel 252. The detachable panel 252 may also take the appearance of and function as a greeting card. Printed material (e.g., designs, sentiment, etc.) may be printed directly on interior and exterior surfaces (i.e., top and bottom sides) of the detachable panel 252.

Prior to removal, the detachable panel 252 may be positioned underneath the second body panel 124 such that an interior surface of the detachable panel 252 contacts an exterior surface of the second body panel 124. In the embodiment shown, the detachable panel 252 extends past the front edge 256 of the first body panel 122 and the front edge 258 of the second body panel 124. When in the collapsed configuration (FIG. 16), the detachable panel 252 may extend to the tenth fold line 226 between the intermediate viewing panel 220 and the outer viewing panel 230. It is contemplated, however, that the detachable panel 252 may be other sizes and shapes while still achieving the object of the present disclosure. For example, the detachable panel 252, in the illustrated embodiment, has a width dimension approximately equal to width dimensions of the first and second body panels 122, 124. In an alternate embodiment, the detachable panel 252 may have a width dimension approximately equal to a width dimension of the viewer 100 in the collapsed position. In this embodiment the detachable panel 252 would cover most of the second and third side panels 136, 136 in FIG. 16. It should be noted that the detachable panel 252 has the added benefit of covering and protecting any lenses in the viewing apertures 238 during both storage and the mailing process.

As previously mentioned, the viewer 100 may comprise a unitary construction. In other words, the various panels comprising the viewer 100 may be manufactured from a single piece of paper or cardstock. In that regard, FIGS. 17 and 18 illustrate die-cut blanks 260 of cardstock or paperboard material that can be folded along the illustrated fold lines to make the viewer 100. By forming the viewer 100 from a single unitary piece of cardstock, the cardstock may be run through a printer prior to being cut out to print a design, coloring, a pattern, advertisement, or other indicia on one or both sides of the viewer 100.

With reference to FIG. 17, the portions of the blank 260 are identified by the reference characters discussed above with respect to the assembled viewer 100. Starting with the viewing portion 102, the outer viewing panel 230 is folded inward at the tenth fold line 226 towards the interior surface of the intermediate viewing panel 220 while the intermediate viewing panel 220 is folded inward at the ninth fold line 224 towards the interior surface of the inner viewing panel 210. The inner viewing panel 210 is folded inward at the eighth fold line 222 towards the interior surface of the second body panel 124, and the viewing panel tabs 234 on the outer viewing panel 230 are folded inward at their respective viewing tab fold lines 236 to be secured to the interior surface of the second body panel 124.

The panels of the body portion 104 may also be folded inward to enclose the viewing portion 102. The first body panel 122 may fold inward at the first fold line 140 towards the interior surface of the first side panel 132, which may fold inward at the second fold line 142 towards the interior surface of the second side panel 134. The second side panel 134 may fold inward at the third fold line 144 towards the interior surface of the second body panel 124, and the third side panel 136 may fold inward at the fourth fold line 146 towards the interior surface of the second body panel 124. The fourth side panel 138 may fold inwards at the fifth fold line 148 towards the interior surface of the first body panel 122 while the side tab 150 may fold inwards at the side tab fold line 152 towards the interior surface of the third side panel 136. As such, the fourth side panel 138 may be adjacent to the side tab 150 so that the side tab 150 may be secured to the fourth side panel 138. The back panel 126 may be folded inward towards the interior surface of the first body panel 122 at the sixth fold line 156. The third body panel 128 may fold inward at the seventh fold line 158 towards the interior surface of back panel 126. A portion of the third body panel 128 may be secured to the exterior surface of the second body panel 124.

As previously discussed, the viewer may also comprise a fifth side panel 180 and a sixth side panel 186, which may be part of the blank 260 illustrated in FIG. 17. The fifth side panel 180 may be adjacent the first side panel 132 at a fifth side panel fold line 262, and the sixth side panel 186 may be adjacent the fifth side panel 180 at a sixth side panel fold line 264. The fifth side panel 180 may fold at the fifth side panel fold line 262 toward an exterior surface of the first side panel 132. An interior surface of the fifth side panel 180 may be releasably or permanently secured to the exterior surface of the first side panel 132. The sixth side panel 186 may fold at the sixth side panel fold line 264 towards the exterior surface 184 of the fifth side panel 180 and be releasably or permanently secured to the exterior surface 184 of the fifth side panel 180.

FIG. 18 depicts the blank 260 of FIG. 17 with the addition of the detachable portion 250. As such, the various panels discussed with respect to the blank in FIG. 17 apply to FIG. 18, and FIG. 18 further shows the blank 260 having a detachable panel 252 that is removeably coupled to the third body panel 128 along a plurality of perforations 254. When the third body panel 128 is folded at the seventh fold line 158 towards the interior surface of the back panel 126, the detachable panel 252 is also moved with the third body panel 128. Because the detachable panel 252 is part of a single die-cut blank with the other panels, promotional material may be printed one or both sides of the detachable panel 252 at the same time a background, pattern, or other indicia is printed on the other panels of the viewer. Additionally, eliminating the need to assemble promotional material with a separate viewer may decrease the cost of manufacturing the viewer for promotional purposes.

Turning to FIGS. 19-22, various views of an alternative embodiment of a collapsible virtual reality viewer 300 in an expanded configuration are provided. Similar to viewer 100, the viewer 300 is formed from a plurality of panels that comprise a viewing portion 302 and a body portion 304 of the viewer 300. Unlike with viewer 100, the body portion 304 and viewing portion 302 may be constructed from separate sheets of material; however, the body portion and the viewing portion may be permanently secured together such that they are configured to collapse and expand together without additional assembly or disassembly by the user. Further, the viewer 300 may be configured to receive a virtual reality display device without requiring the user to couple or uncouple any of the panels.

As illustrated in FIG. 19, the body portion 304 may at least partially enclose or surround the viewing portion 302 when the viewer 300 is in the expanded configuration. The body portion 304 may include a first body wall 312 and a second body wall 314 opposite the first body wall 312. The first body wall 312 may comprise a first body panel 322 while the second body wall 314 may comprise a second body panel 324 and a third body panel 326 that are both substantially parallel to the first body panel 322. The third body panel 326 of viewer 300 is different than the third body panel 128 of viewer 100 in that the third body panel 326 may have an identical size and shape of the second body panel 324 such that each of the third body panel 326 and the second body panel 324 form half of the second body wall 314.

The first body wall 312 and the second body wall 314 may be joined at one end by a first side wall 306 and at an opposite end by a second side wall 308. The first side wall 306 may comprise a first side panel 332 and a second side panel 334, while the second side wall 308 may include a third side panel 336 and a fourth side panel 338. More specifically, at one end, the first side panel 332 may be adjacent the first body panel 322 at a first fold line 340 and may be adjacent the second side panel 334 at a second fold line 342, while the second side panel 334 may be adjacent the second body panel 324 at a third fold line 344. Similarly, one the other side, the third side panel 336 may be adjacent the third body panel 326 at a fourth fold line 346 and adjacent the fourth side panel 338 at a fifth fold line 348. Unlike viewer 100, the third side panel 336 and the fourth side panel 338 may be coupled together directly via the fifth fold line 348. The other end of the fourth side panel 338 may be adjacent the first body panel 322 along a sixth fold line 350.

As illustrated in FIG. 19, the first side panel 332 and the second side panel 334 may form a first angle 353 with respect to each other that is equal to a second angle 354 between the third side panel 336 and the fourth side panel 338. The first angle 353 and the second angle 354 may be determined by the shape of the panels of the viewing portion 302 that are positioned within the body portion 304. In some embodiments, the first and second angles 353 and 354, respectively, are each less than 180 degrees. For example, the first and second angles 353 and 354, respectively, may each be approximately 115 degrees. In alternative embodiments, the first and second angles 353 and 354, respectively, may each be 180 degrees when in an expanded configuration such that the first side wall 306 is parallel to the second side wall 308.

Although not illustrated in FIG. 19, some embodiments of viewer 300 include additional side panels layered on one or more of the side panels 332334, 336, and 338 in a similar manner described with respect to viewer 100. Additionally, the additional side panels may comprise openings, similar to openings 190 and 192 in FIG. 1, to form a shallow slot for holding a magnet or another object having magnetic properties, such as a coin or washer. A user may move the magnet or other object within the confines of the openings to interact with a virtual reality display device positioned in the viewer 300.

All together, the walls of the body portion 304 of the viewer 300 cooperate to form and define an inner cavity within which the viewing portion 302 may be at least partially disposed. Turning to FIG. 23, a rear perspective view of the viewing portion 302 is provided with the body portion 304 shown in dashed lines for clarity. The viewing portion 302 may comprise an inner viewing panel 410, an outer viewing panel 430, a back panel 440, an intermediate viewing panel 420, and a bottom panel 450.

When the viewer 300 is in the expanded configuration, as shown in FIG. 23, the back panel 440, the inner viewing panel 410, and the outer viewing panel 430 are substantially parallel to one other. The inner viewing panel 410 may be positioned between the back panel 440 and the outer viewing panel 430 and may be coupled to the back panel 440 via a connecting panel 442. When in the expanded configuration, the intermediate viewing panel 420 may be substantially perpendicular to the back panel 440, the inner viewing panel 410, and the outer viewing panel 430. At the same time, the intermediate panel 420 may be substantially parallel to the bottom panel 450 and the connecting panel 442 coupling the back panel 440 and the inner viewing panel 410. As such, the intermediate viewing panel 420 may be positioned underneath of and parallel to the first body panel 322 of the body portion 304, and the bottom panel 450 may be positioned above and parallel to the second and third body panels 324 and 326, respectively, of the body portion 304.

Being parallel to one another, the inner viewing panel 410 and the back panel 440 may form a slot 460 between each other. The slot 460 may be used to hold a virtual reality display device, such as the virtual reality display device 194 shown in FIG. 4. The slot 460 formed between the inner viewing panel 410 and the back panel 440 may be spaced apart from the outer viewing panel 430 by the intermediate viewing panel 420. Specifically, the intermediate viewing panel 420 may be adjacent the outer viewing panel 430 at a seventh fold line 426 and may be adjacent either the inner viewing panel 410 or the back panel 440 at another fold line. In the embodiment illustrated in FIG. 23, the intermediate viewing panel 420 is adjacent the back panel 440 along an eighth fold line 424. The opposite end of the back panel 440 may be adjacent the connecting panel 442 that spaces apart the back panel 440 and the inner viewing panel 410. The connecting panel 442 may be adjacent the back panel 440 along a ninth fold line 422 and adjacent the inner viewing panel 410 at a tenth fold line 428. Accordingly, the connecting panel 442 may form a bottom portion of the slot 460, and the portion of the intermediate viewing panel 420 between the back panel 440 and the inner viewing panel 410 may form a top portion of the slot 460.

In some aspects, at a side opposite the connecting panel 442, the inner viewing panel 410 is adjacent a second connecting panel 470 along an eleventh fold line 472. The second connecting panel 470 may be used to couple the inner viewing panel 410 to the intermediate viewing panel 420. In some aspects, the second connecting panel 470 is frictionally engaged with a portion of an interior surface of the intermediate viewing panel 420 to secure the inner viewing panel 410 to a position perpendicular to the intermediate viewing panel 420. In other aspects, an adhesive or coupling mechanism is used to secure the second connecting panel 470 to the intermediate viewing panel 420.

A user may insert a virtual reality display device in the slot 460 by sliding the device between the back panel 440 and the inner viewing panel 410 in a similar manner shown with respect to viewer 100 in FIG. 4. Because the slot 460 of viewer 300 is formed by panels permanently coupled to one another along fold lines, the user does not need to do any additional assembly or disassembly to the viewer 300 to position the virtual reality display device into the slot 460 for use. In some aspects, the side panels 332334, 336, and 338 of the body portion 304 may each include a tab 380 extending from side panels to at least partially cover the opening of the slot 460 as shown in FIGS. 19-21. Each tab 380 may abut the respective side panel along a fold line such that the tabs 380 may be folded by a user. The user may fold one or more of the tabs 380 away from the slot 460 to insert a virtual reality display device into the slot 460 and may then fold the tabs 380 back over the slot 460. In this way, the tabs 380 may be used to help secure the virtual reality display device within the slot 460 to reduce the risk of the device inadvertently sliding out of the slot 460 when in use.

Although FIG. 23 shows the intermediate viewing panel 420 being adjacent the back panel 440 via along a fold line, it is contemplated that that other configurations may be used to form the slot 460. For example, in other aspects of the viewer 300, the intermediate viewing panel 420 may be adjacent the inner view panel 410 via a fold line, and the first body wall 322 may form the top portion of the slot 460.

As previously described, when in the expanded configuration, the viewer 300 is designed to allow a user to see a virtual reality display on a virtual reality display device that has been inserted into the slot 460. As such, the inner viewing panel 410 and the outer viewing panel 430 may include one or more apertures through which a user can see the virtual reality display. For example, the inner viewing panel 410 may include a display aperture 416 that provides a view of the virtual reality display device in the slot 460. Although not fully visible in FIG. 23, the display aperture 416 of viewer 300 may comprise a similar shape and size as the display aperture 216 of viewer 100 illustrated in FIGS. 6-7. Similarly, just as with the display aperture 216 of viewer 100, some embodiments of viewer 300 may include a reinforcement panel that overlays and is secured to the inner viewing panel 410 to increase the strength of the inner viewing panel 410 around the display aperture 416. In some aspects, any such reinforcement panel is of a similar size and shape as the inner viewing panel 410 such that the reinforcement panel reinforces the entire perimeter of the display aperture 416. In other aspects, the inner viewing panel 410 may include one or more reinforcement panels that extend around only a portion of the inner viewing panel 410.

Additionally, the outer viewing panel 430, which is parallel to the inner viewing panel 410, may include one or more viewing apertures that provide a user with a view of the inside of the viewer 300 to see the virtual reality display. For instance, the outer viewing panel 430 may include two circular viewing apertures 438A-B positioned on the outer viewing panel 430 to align with a user's eyes when the first body panel 322 is positioned against a user's forehead. Accordingly, a user may position the viewer 300 against the user's head so that each eye can see through a viewing aperture 438A-B in the outer viewing panel 430 and through the display aperture 416 in the inner viewing panel 410 to see a virtual realty display on a virtual reality display device inserted into the slot 460. In some embodiments, the viewer 300 includes a lens in each of the viewing apertures 438A-B.

In some embodiments, the viewing portion 302 includes a plurality of reinforcement panels secured to the outer viewing panel 430. FIG. 24 illustrates the outer viewing panel 430 and a plurality of reinforcement panels 510 in an exploded view. In exemplary aspects, each half of the outer viewing panel 430 has three corresponding reinforcement panels 510. For example, the half of the outer viewing panel 430 with the viewing aperture 430A that is configured to be used with a user's left eye may include reinforcement panels 514A, 516A, and 518A while the half of the outer viewing panel 430 with the viewing aperture 430B configured to be used with a user's right eye may include reinforcement panels 514B, 516B, and 518B. Reinforcement panels 514A, 516A, and 518A may of be the same or substantially the same shape and size of the half of the outer viewing panel 430 to which they correspond and may be mirror images of the reinforcement panels 514B, 516B, and 518B. Additionally, all the reinforcement panels 510 may have a viewing aperture positioned such that the viewing apertures of reinforcement panels 514A, 516A, and 518A are all aligned with the viewing aperture 438A and the viewing apertures of reinforcement panels 514B, 516B, and 518B are all aligned with the viewing aperture 438B.

In some aspects, one or more of the reinforcement panels 510 are directly connected to one another via a fold line such that some of the panels are part of a larger panel. For instance, reinforcement panels 514A and 516A may abut along first reinforcement fold line 517A to form panel 512A, and reinforcement panels 514B and 516B may abut second first reinforcement fold line 517B to form panel 512B. In other words, panels 512A and 512B may each have a similar shape and size to the entire outer viewing panel 430 but are folded in half such that each panel is used to reinforce only one half of the outer viewing panel 430. The die cut of the viewing portion shown in FIG. 29A further illustrates this configuration.

It is also contemplated that, in other aspects, each reinforcement panel 510 is formed as a separate panel such that they do not adjoin any other reinforcement panels 510 along a fold line. Alternatively, each of the reinforcement panels 510 may be secured to at least one other reinforcement panel 510 via a fold line. Further, it is also contemplated that each reinforcement panel 510 may be configured to correspond to the entire outer viewing panel 430, rather than only half, and the number of reinforcement panels 510 may be less than or greater than what is depicted in FIG. 24.

As the viewer 300 is designed to be used when placed up against a user's face, exemplary embodiments are adapted to fit around the user's face. For example, the front edges of the first body panel 322, the second body panel 324, and the third body panel 326 may be curved inward to accommodate the curvature of a user's face. Additionally, the outer viewing panel 430 may be shaped to include an arched edge between the viewing apertures 438A-B to accommodate a user's nose when viewing a virtual reality display through the viewing apertures 438A-B.

Returning to FIG. 20, the viewer 300 may comprise a coupling mechanism 360 to couple the viewing portion 302 to the body portion 304 such that the viewing portion 302 and the body portion 304 may be configured to move together between expanded and collapsed configurations. In exemplary embodiments, for example, the coupling mechanism 360 comprises a series of hinging panels separating by a plurality of fold lines such that the panels form a hinge that allows the viewer 300 to move between expanded and collapsed configurations. The coupling mechanism 360 may comprise a first hinging panel 362, a second hinging panel 364 abutting the first hinging panel 362 along a first hinging fold line 372, and a third hinging panel 366 abutting the second hinging panel 364 along a second hinging fold line 374. The first hinging panel 362 may be coupled to the first body panel 322 of the body portion 304 while the third hinging panel 366 may be coupled to the back panel 440 of the viewing portion 302. The second hinging panel 364 may be left not directly secured to other panels of the viewer 300.

In some aspects, the first hinging panel 362 is adjacent a portion of the first body panel 322 along a third hinging fold line 370. The third hinging fold line 370 may extend along a portion of the side of the first body panel 322 that is opposite the side of the first body panel 322 that is proximate to the back panel 440. Accordingly, the first hinging panel 362 may extend across the length of the first body panel 322. As shown in FIG. 20, the first hinging panel 362 may extend across an interior surface of the first body panel 322 such that the first hinging panel 362 is positioned between the first body panel 322 and the intermediate viewing panel 420 (not shown in FIG. 20). In other aspects, the first hinging panel 362 overlays a portion of the exterior surface of the first body panel 322 such that it is visible from an exterior view of the viewer 300. At least a portion of the surface of the first hinging panel 362 that contacts the surface of the first body panel 322 may be secured to the first body panel 322 via adhesive or a bonding agent to prevent the first hinging panel 362 from shifting. The third hinging panel 366 may be secured to a portion of the back panel 440 via adhesive or bonding agent. In exemplary aspects, the third hinging panel 366 is central to a central portion of the back panel 440.

The body portion 304 of the viewer 300 may be secured to the viewing portion 302 in other areas in addition to the coupling mechanism 360 between the first body panel 322 and the back panel 440. In one aspect, layers of adhesive in select areas may be used to directly couple the body portion 304 to the viewing portion 302. For instance, one or more layers of adhesive may be used between the bottom panel 450 of the viewing portion 302 and the second body panel 324 and the third body panel 326 of the body portion 304. Further, in some aspects, the connecting panel 442, which forms the bottom portion of the slot 460, may be secured to a portion of the bottom panel 450. These additional coupling mechanisms may be used to help maintain proper positioning of the various panels relative to one another as the viewer 300 is moved between the expanded and collapsed configurations. Through the hinging mechanism and, in some aspects, the use of adhesive in pre-defined locations, the viewer 300 may be expanded and collapsed solely through the application of a small amount of force without requiring additional assembly or disassembly from the user.

When the viewer 300 is in the expanded configuration, the second hinging panel 364 and the third hinging panel 366 may be substantially flush with the back panel 440 and substantially perpendicular to the first hinging panel 362, as shown in FIGS. 20 and 21. When the viewer 300 is moved into a collapsed configuration, the second hinging panel 364 is folded relative to the first and second hinging fold lines 372 and 374, as shown in FIG. 25.

As seen in the partially collapsed view depicted in FIG. 25, the viewer 300 collapses in a similar manner as viewer 100. The first side panel 332 and the second side panel 334 may fold at the second fold line 342 to move toward each other. Likewise, the third side panel 336 and the fourth side panel 338 fold at the fifth fold line 348 so that the third side panel 336 moves closer to the fourth side panel 338. As the side panels 332, 334, 336, and 338 are folded inwards, the first angle 353 and the second angle 354 decrease. At the same time, the first body panel 322 is moved closer to the second body panel 324 and the third body panel 326.

The viewing portion 302 disposed within the cavity of the body portion 304 also collapses. Specifically, the intermediate viewing panel 420 slides forward to move out from underneath the first body panel 322, allowing the first body panel 322 to be moved closer to the second body panel 324 and the third body panel 326. The outer viewing panel 430 folds in toward the intermediate viewing panel 420 along the seventh fold line 426. The back panel 440 folds outward from the intermediate viewing panel 420 at the eighth fold line 424 while folding in at the ninth fold line 422 towards the connecting panel 442.

Unlike with the viewer 100, however, the entire back panel 440 folds further into the cavity formed by the body portion 304, rather than folding onto itself. As the back panel 440 folds, the back panel 440 moves closer to the bottom panel 450, which causes the inner viewing panel 410 to also move closer to the bottom panel 450. The hinging panels 362, 364, and 366 allow the entire back panel 440 to fold inward while remaining coupled to the body portion 304. When collapsing, the second hinging panel 364 folds inward at the first hinging fold line 372 such that it moves towards the first hinging panel 362. At the same time, the second hinging panel 364 also folds at the second hinging fold line 374 to move toward the third hinging panel 366. Once fully collapsed, the second hinging panel 364 is at least partially layered between the first hinging panel 362 and the third hinging panel 366.

FIGS. 26-27 illustrate top perspective and bottom perspective views, respectively, of the viewer 300 when in a fully collapsed configuration. Similar to viewer 100, in this configuration, a top surface 444 of the viewer 300, shown in FIG. 26, comprises the first side panel 332, the first body panel 322, and the fourth side panel 338. The bottom surface 446 of the viewer 300 in a collapsed configuration, shown in FIG. 27, comprises the second side panel 334, the second body panel 324, the third body panel 326, and the third side panel 336. The intermediate viewing panel 420 and at least a portion of the outer viewing panel 430 may be visible and sticking out between the top surface 444 and the bottom surface 446. The inner viewing panel 410, the first connecting panel 442 (not visible), and the second connecting panel 470 may be layered between the outer viewing panel 430 on one side and the back panel 440 and intermediate viewing panel 420 on the other side. The viewer 300 may move from the collapsed configuration to an expanded configuration when a user pushes together the second fold line 342 and the fifth fold line 348.

When in the collapsed configuration, the viewer 300 may be relatively flat. For example, when in a fully collapsed configuration, the viewer 300 may have a thickness between the top surface 444 and the bottom surface 446 that is less than one-half of an inch in some embodiments. In some aspects, the thickness may be less than one-fourth of an inch. The ability of the viewer 300 to be placed in a collapsed position to have a thin profile may be desirable when using the viewer 300 for promotional purposes. For example, the viewer 300 with promotional material, such as advertisements, may be handed out by businesses or mailed to potential customers.

An embodiment of the viewer 300 with promotional materials is depicted in FIG. 28. In this embodiments, the viewer 300 may include a detachable portion comprising a detachable panel 610 coupled to the body portion 304 at a fold line. In some embodiments, such as the one illustrated in FIG. 28, this fold line is a plurality of perforations 612, and the detachable panel 610 is coupled to the first body panel 322 along the plurality of perforations 612. Similar to the detachable panel 252 of viewer 100 depicted in FIG. 16, the plurality of perforations 612 may be the only mechanism attaching the detachable panel 610 to the rest of the viewer 300. Accordingly, the detachable panel 610 may be completely detachable from the rest of the viewer 300 along the plurality of perforations 612. In exemplary aspects, the plurality of perforations 612 couples the detachable panel 610 along a side of the first body panel 322 that is opposite the side of the first body panel 322 that abuts the first hinging panel 362 via the third hinging fold line 370. The detachable panel 610 may be of a similar size and shape as detachable panel 252 of viewer 100, and the detachable panel 610 may include printed promotional material or may be secured to promotional material in the same manner as described with respect to detachable panel 252.

Each portion of the viewer 300 may comprise a unitary construction. In other words, the various panels comprising the viewing portion 302 may be manufactured from a single piece of paper or cardstock while the panels comprising the body portion 304 may be manufactured from a second, single piece of paper or cardstock. In that regard, FIGS. 29A-B and 30A-B illustrate die-cut blanks of cardstock or paperboard material that can be folded along the illustrated fold lines to make the body portion 304 and the viewing portion 302 of the viewer 300. By forming each portion of the viewer 300 from a single unitary piece of cardstock, the cardstock may be run through a printer prior to being cut out to print a design, coloring, a pattern, advertisement, or other indicia on one or both sides of the viewer 300.

With reference to FIGS. 29A-B, portions of the blanks 710A and 710B are identified by the reference characters discussed above with respect to the assembled viewer 300. Starting with FIG. 29A, blank 710A may be folded to form the viewing portion 302. The reinforcement panels 510 may be folded along a plurality of fold lines to overlay the outer viewing panel 430. Specifically, reinforcement panel 514A may fold inward along first reinforcement fold line 517A toward reinforcement panel 516A. Reinforcement panels 514A and 516A (collectively referred to as panel 512A) may then fold inward at third reinforcement fold line 504 toward the outer viewing panel 430. Reinforcement panel 518A may also fold inward at a fourth reinforcement fold line 502 toward the outer viewing panel 430. Reinforcement panels 514B, 516B, and 518B may fold along fold lines 517B, 508, and 506 in a similar fashion.

The bottom panel 450 is folded inward at the twelfth fold line 436 toward the outer viewing panel 430. The outer viewing panel 430 is folded inward at the seventh fold line 426 towards the interior surface of the intermediate viewing panel 420 while the intermediate viewing panel 420 is folded inward at the eighth fold line 424 towards the interior surface of the back panel 440. The connecting panel 442 is folded inward at the ninth fold line 422 toward the back panel 440, and the inner viewing panel 410 is folded inward at the tenth fold line 428 toward the connecting panel 442 until the inner viewing panel 410 is parallel to the back panel 440. As the inner viewing panel 410 is folded upward, the second connecting panel 470 folds at the eleventh fold line 472 such that a portion of the intermediate viewing panel 420 overlays the second connecting panel 470.

Blank 710B provides various panels that may be folded to form the body portion 304 in which the viewing portion 302 is later enclosed. The first body panel 322 may fold inward at the first fold line 340 towards the interior surface of the first side panel 332, which may fold inward at the second fold line 342 towards the interior surface of the second side panel 334. The second side panel 334 may fold inward at the third fold line 344 towards the interior surface of the second body panel 324. The other side may of the first body panel 322 may be folded in a similar way such that the first body panel 322 may fold inward at the sixth fold line 350 toward the fourth side panel 338, and the fourth side panel 338 may fold inward at the fifth fold line 348 toward the third side panel 336. The third side panel 336 may fold inward toward the third body panel 326 at the fourth fold line 346. The first hinging panel 362 may fold inward at the third hinging fold line 370 toward the interior surface of the first body panel 322 until a portion of the first body panel 322 overlays the first hinging panel 362, and the second hinging panel 364 folds in at the first hinging fold line 372 toward the first hinging panel 362. To couple the viewing portion 302 formed by blank 710A to the body portion 304 formed by blank 710B, the third hinging panel 366 may be secured to the exterior surface of the back panel 440 via adhesive.

FIGS. 30A-B depict the blanks used to form the viewer 300 with a detachable portion as depicted in FIG. 28. The viewing portion 302 is formed with blank 710A as described above with reference to FIG. 29A. FIG. 30B depicts the blank 710B of FIG. 29B with the addition of the detachable portion. As such, the various panels discussed with respect to the blanks 710A and 710B in FIGS. 29A-29B apply to FIGS. 30A-30B. FIG. 30A further shows the blank 710B having a detachable panel 610 that is removeably coupled to the first body panel 322 along a plurality of perforations 612. Because the detachable panel 610 is part of a single die-cut blank 710B with the other panels of the body portion 304, promotional material may be printed on one or both sides of the detachable panel 252 at the same time a background, pattern, or other indicia is printed on the other panels of the body portion 304. Additionally, eliminating the need to assemble promotional material separately may decrease the cost of manufacturing the viewer for promotional purposes.

While the invention has been described generally as a collapsible virtual reality (VR) viewer assembly, the concepts can be readily applied to create a collapsible augmented reality (AR) viewer assembly. When used a VR viewer, the user only needs to see the display screen of the smartphone when it is placed in the VR viewer. The remainder of the smartphone may be generally hidden from view and the viewer simply needs to only hold the phone in the slot 460. In the VR context, everything that is displayed on the display screen is created or virtual.

In an AR context, however, images of real items are displayed on a display screen and the real items are augmented with the placement of some created or virtual items on the display. The display of the real items is augmented with the addition of virtual items being displayed. AR is generally done by having a camera film a real environment and display the image on a display in real time (i.e., “live”). This can be accomplished with a smartphone, as it has not only a display screen, but also a camera. The primary camera on most smartphones is on a side opposite the display screen. Therefore, when the smartphone is received in the slot 460, the back panel 440 generally covers the rear of the smartphone (i.e., the side opposite the display screen, since the display screen is facing the user). An aperture 448 may be provided in the back panel 440 in certain embodiments to provide an opening through the back panel 440 such that a camera of the smartphone may be used while the smartphone is received in the slot 460. The aperture 448 aligns with the camera of the smartphone when the smartphone is fully received in the slot 460. The viewer can then hold the smartphone while the smartphone “films” the environment in front of the viewer and displays it on the display screen to be augmented in an AR setting.

Embodiments of the present invention have been described with the intent to be illustrative rather than restrictive. Alternative embodiments will become apparent to those skilled in the art that do not depart from the scope of the invention. A skilled artisan may develop alternative means of implementing the aforementioned improvements without departing from the scope of the present invention. It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations and are contemplated as within the scope of the claims.
