Description

    CROSS REFERENCE TO RELATED APPLICATION
  • This application claims the benefit of priority under 35 U.S.C. §119(e) of U.S. Provisional Application No. 61/794,163 filed Mar. 15, 2013, the disclosure of which is hereby incorporated by reference in its entirety.
  • TECHNICAL FIELD
  • The subject matter of the present disclosure relates to case structures, and more particularly, to case structures providing waterproof or water-resistant capabilities.
  • BACKGROUND
  • A number of portable electronic devices advantageous for handheld operations have been developed, such as Apple's iPhone®, various generations of Apple's iPad®, various generations of Samsung's Galaxy® phone devices, Galaxy® series tablets, Android® tablets, tablet PCs, smart phones, other touch-panel devices, digital cameras, camcorders, e-readers, various generations of Kindle®, various generations of Nook®, and many other devices. The development of these electronic devices has provided useful functions for daily life and business.
  • Many portable electronic devices are not waterproof. However, portable electronic devices may often be required to operate under conditions or in environments that may increase the possibility of physical impact, water/moisture/dust damage, temperature effects, etc. The operating or environmental conditions may therefore affect portable electronic devices' reliability and operability. Thus, a measure to provide some level of shock/drop/impact-, water-, dust-, and/or chemical-resistance and/or other forms of protection may be desired to protect portable electronic devices or improve their operability or reliability under various operating conditions.
  • Some commercially available cases for protecting electronic devices may offer certain level of protection, with some of them conforming to the IPX5 water-resistance standard defined in the International Electrotechnical Commission (IEC) document No. 60529. Generally, cases that conform to the IPX5 water-resistance standard may be limited to protection of the enclosed devices against water jets of prescribed characteristics. For example, some cases may protect enclosed devices against water projected at all angles through a 6.3 mm nozzle at a flow rate of 12.5 liters/minute and a pressure of 30 kPa for at least 3 minutes from a distance of 3 meters. However, the cases may not protect devices operated under different conditions.
  • Some cases, while providing protection above the IPX5 standard, may have large dimensions, turning portable devices into bulky and less-convenient devices. Some other cases prevent the operation of portable electronic devices when enclosed in the cases, making underwater or other operations impossible.
  • With regard to the above-mentioned conditions, some protecting structures for smart phones or tablet PCs have been developed, such as a combinable case structure or a bag-type shield. A combinable case structure, in some circumstances, may be better than a bag-type shield and may be widely used. However, it may be desirable to provide protective casings that may provide one or more of water-resistance, ease of operability, underwater operations, impact absorption, enhanced structural strength, and acceptable dimensions or portability.
  • SUMMARY
  • The present disclosure provides a water-resistant casing for a portable electronic device. According to one aspect, the water-resistant casing may include a bottom cover. The bottom cover may include an impact-absorbing housing configured to provide water resistance and impact absorption to the portable electronic device, and a first water-sealing structure coupled to a perimeter of the bottom cover and configured to provide water resistance. The water-resistant casing may also include at least one frame configured to be detachably coupled to the bottom cover. The at least one frame may include a second water-sealing structure configured to correspond to the first water-sealing structure. The water-resistant casing may further include a water-resistant film coupled to the at least one frame, and configured to enable a user to operate the portable electronic device through the water-resistant film. The water-resistant casing may further include an impact-absorbing seal coupled to a perimeter of the water-resistant film and configured to provide water resistance and impact absorption. The water-resistant casing may further include a coupling structure mounted on at least one edge of at least one of the bottom cover and the at least one frame. The coupling structure may be configured to secure the bottom cover and the at least one frame to one another along at least a portion of the perimeter of the water-resistant casing. The water-resistant casing may further include a mounting structure detachably coupled to or integrated with the bottom cover. The mounting structure may be configured to enable mounting of the portable electronic device to another object.
  • The present disclosure further provides a water-resistant casing for an electronic tablet. The water-resistant casing may include a bottom cover. The bottom cover may include an impact-absorbing housing configured to provide water resistance and impact absorption to the electronic tablet, and a first water-sealing structure coupled with a perimeter of the bottom cover and configured to provide water resistance. The water-resistant casing may also include a frame configured to be detachably or integrally coupled to the bottom cover. The frame may include a second water-sealing structure configured to correspond to the first water-sealing structure. The water-resistant casing may further include a water-resistant film coupled to the frame, and configured to enable a user to operate the electronic tablet through the water-resistant film. The water-resistant casing may further include an impact-absorbing seal coupled with a perimeter of the water-resistant film and configured to provide water resistance and impact absorption. The water-resistant casing may further include at least two latches distributed along at least two edges of the bottom cover. The at least two latches may be configured to secure the bottom cover and the frame to one another, such that the water-resistant casing is sealed. The water-resistant casing may further include a mounting structure detachably coupled to or integrated with the bottom cover. The mounting structure may be configured to enable a mounting of the electronic tablet to an object. The mounting structure may include three first engaging elements and three engaging slots between the three first engaging elements. The three engaging elements and three engaging slots may be configured to enable a rotatable mounting or releasing of the electronic tablet with respect to the object.
  • The present disclosure further provides a protective casing for a portable electronic device. The protective casing may include a bottom cover. The bottom cover may include an impact-absorbing housing configured to provide water resistance and impact absorption to the portable electronic device, and a convex-concave pattern having an enhanced thickness at a convex area. The convex-concave pattern may be configured to provide additional impact absorption or shock resistance to the portable electronic device. The protective casing may also include a first frame detachably or integrally coupled to the bottom cover. The first frame may include a groove configured to surround at least a portion of a periphery of the bottom cover, and a plurality of protrusions being distributed along a side wall of the groove. The protective casing may further include a second frame configured to be detachably coupled to the first frame. The second frame may include a convex portion configured to cooperate with the groove to enclose the protective casing along at least a portion of the perimeter of the protective casing, and a plurality of engaging slots corresponding to the protrusions. The engaging slots may be configured to engage with the protrusions to provide a coupling of the protective casing. The protective casing may further include a water-resistant film coupled to at least one of the first frame and the second frame, and configured to enable a user to operate the portable electronic device through the water-resistant film. The protective casing may further include an impact-absorbing seal coupled to a perimeter of the water-resistant film and configured to provide water resistance and impact absorption. The protective casing may further include two latches distributed along two edges of the bottom cover. The two latches may be configured to provide a more secure sealing of the protective casing.

  • DETAILED DESCRIPTION
  • The aforementioned and other aspects, solutions, and advantages of the presently claimed subject matter will become apparent from the following descriptions and corresponding drawings. The described embodiments may further clarify the presently claimed subject matter and shall not be construed to limit the scope of the presently claimed subject matter.
  • The detailed description may include specific details for illustrating various aspects of case structures for portable electronic devices. However, it will be apparent to those skilled in the art that the disclosure may be practiced without these specific details. In some embodiments, well-known elements may be shown in block diagram form, or omitted, to avoid obscuring the inventive concepts presented throughout this disclosure.
  • As an example, various aspects of a case structure may be illustrated by describing components that are coupled or connected together. However, the disclosure, while using Apple iPhone 5® and Apple iPad® mini devices, as illustrations, may be practiced with other portable electronic devices. As used herein, the terms “coupled” and “connected” may be used to indicate either a direct connection or coupling between two components or, where appropriate, an indirect connection or coupling to one another through intervening or intermediate components. In contrast, when a component is referred to as being “directly coupled” or “directly connected” to another component, there may be no intervening elements.
  • Relative terms such as “lower” or “bottom” and “upper” or “top” may be used herein to describe one element's relative relationship to another element illustrated in the drawings. It would be apparent to those skilled in the art that relative terms are intended to encompass different orientations of a portable electronic device placed within a case structure in addition to the exemplary orientation depicted in the drawings. As an example, if a case structure for a portable electronic device in the drawings is turned over, flipped, and/or rotated, elements described as being on the “bottom” side of the other elements may then be oriented on the “top” side of the other elements. The term “bottom” may therefore encompass both an orientation of “bottom” and “top” depending on the particular orientation of the case structure.
  • Various aspects of case structures may be illustrated with reference to one or more exemplary embodiments. As used herein, the term “exemplary” means “serving as an example, instance, or illustration,” and should not necessarily be construed as preferred or advantageous over other embodiments of a case structure disclosed herein.
  • FIG. 1A illustrates a perspective view of an exemplary case structure 1000. FIG. 1B illustrates an exploded view of case structure 1000 of FIG. 1A. Referring to FIGS. 1A and 1B, case structure 1000 is provided for housing or enclosing a portable electronic device (not shown), such as an Apple® iPhone 5 device, and therefore enables preventing or reducing of the likelihood of shock/drop/impact-, water-, dust-, and/or chemical-damage of the portable electronic device. Case structure 1000 may be substantially waterproof, such as waterproof in compliance with class IP68 according to the U.S. National Electrical Manufacturers Association rating. The types of portable electronic devices that are capable of being enclosed in case structure 1000 may include, but are not limited to, a cell phone, a smart phone, an MP3 player, a portable computer, and a tablet PC, a personal digital assistant, and/or other similar portable electronic devices.
  • Referring to FIGS. 1A and 1B, according to some embodiments, case structure 1000 may include a bottom cover 1, a first frame 2, a film 3, and a second frame 4. In some embodiments, second frame 4 may be detachably coupled to or integrated with first frame 2 so as to form a single piece. Film 3 may be coupled to one or both second frame 4 and first frame 2 and be placed between the two frames. In some embodiments, first frame 2 may be detachably coupled to bottom cover 1. The dimensions and aspect ratios of bottom cover 1 and second frame 4 may be substantially the same or similar. In some embodiments, the dimension of first frame 2 may be substantially similar or slightly smaller than bottom cover 1 and/or second frame 4 so that it may be coupled to or accommodated by bottom cover 1 and second frame 4. Referring to FIG. 1A, case structure 1000 is illustrated in an assembled condition, and thus, some elements of case structure 1000 may not be marked or labeled in FIG. 1A.
  • The material of case structure 1000 may include polypropylene (PP), polycarbonate (PC), thermoplastic polyurethane (TPU), or any other material having similar characteristics. As an example, in some embodiments, the material of bottom cover 1 may include polypropylene; the material of first frame 2 may include polycarbonate; and the material of second frame 4 may include thermoplastic polyurethane. One of ordinary skill in the art would appreciate that the material of each element of the case structure 1000 may not be limited to those described above and may include any other material desired. For example, the material of some elements of case structure 1000 may include metal, alloy, stainless steels, nylons, hard plastics, iron, aluminum, lead, and/or other materials having similar characteristics, or any combination thereof.
  • FIG. 1C illustrates a partial cross-sectional view of case structure 1000 of FIG. 1A. FIG. 1D illustrates a partial, enlarged cross-sectional view of case structure 1000 of FIG. 1A. Referring to FIGS. 1B, 1C, and 1D, bottom cover 1 may include a housing 11. In some embodiments, housing 11 may include a flat structure, such as a flat bed, configured to accommodating or housing a portable electronic device, such as an Apple iPhone® 5 device. The dimensions of housing 11 may correspond to the structure and/or dimensions of the portable electronic device, and may not be limited to those illustrated in FIGS. 1B-1D. In some embodiments, bottom cover 1 may include a groove 14 surrounding at least a portion of the periphery of housing 11. Groove 14 may be formed by, for example, a water barrier 13 and the internal peripheral portion of bottom cover 1. In some embodiments, first frame 2 may have a convex portion 20 corresponding to groove 14. When case structure 1000 is closed, convex portion 20 of first frame 2 may be partially or entirely inserted or disposed in groove 14. One of ordinary skill in the art would appreciate that groove 14 may be included in other places. As an example, in some embodiments, groove 14 may be included in first frame 2 or second frame 4. Correspondingly, in these embodiments, convex portion 20 may be included in the opposing frame or cover, such as bottom cover 1.
  • Referring to FIGS. 1C and 1D, in some embodiments, groove 14 may include a first coupling portion 141 on the side that is further away from housing 11. For example, first coupling portion 141 may be included in the peripheral portion of bottom cover 1. Groove 14 may also include a plurality of second coupling portions 142 on the side that is close to or near housing 11. For example, second coupling portions 142 may be included in water barrier 13. In some embodiments, second coupling portions 142 may be separately or discontinuously disposed between groove 14 and housing 11, such as disposed in water barrier 13.
  • Referring to FIGS. 1C and 1D, in some embodiments, convex portion 20 of first frame 2 may include at least one first coupling element 201 and a plurality of second coupling elements 202, corresponding to first coupling portion 141 and second coupling portions 142, respectively. In some embodiments, when case structure 1000 is closed, and therefore convex portion 20 is in contact with or inserted into groove 14, first coupling element 201 and second coupling elements 202 may be hingedly, rotatably, movably, permanently, detachably, latchably, and/or snugly coupled or engaged with first coupling portion 141 and second coupling portions 142, respectively. First coupling element 201, second coupling elements 202, first coupling portion 141, and second coupling portions 142, may thus form of a water-sealing or water-resistant structure configured to provide water-resistant or waterproof capability to case structure 1000. As an example, first coupling portion 141 and first coupling element 201 may each include a protrusion that may be engaged with each other to form a tight coupling. As another example, second coupling elements 202 may include a plurality of separated protrusions so that they may be engaged with a corresponding plurality of second coupling portions 142, such as a plurality of slots or small openings. Moreover, in some embodiments, the protrusions of second coupling elements 202 may be semi-circle shaped, so that a user may be provided with a smoother and more convenient experience for attaching and/or detaching of case structure 1000. One of ordinary skill in the art would appreciate that to form a water-sealing or water-resistant structure, some but not all first coupling element 201, second coupling elements 202, first coupling portion 141, and second coupling portions 142 may be needed.
  • Referring to FIGS. 1C and 1D, water barrier 13 may further include a plurality of protrusions 162 configured to enhance the strength of water barrier 13. As an example, FIGS. 1C and 1D illustrate that the plurality of protrusions 162 may include one or more triangular-shaped fins configured to provide additional support and structural strength to water barrier 13, so that the likelihood of breaking, distorting, fracturing, chipping, bending, and/or other similar damages may be prevented or reduced.
  • Referring to FIGS. 1C and 1D, case structure 1000 may include a seal strip 5 configured to provide additional water-sealing or water-resistance capability of the water-sealing or water-resistant structure that includes groove 14 and convex portion 20. Additionally, seal strip 5 and the water-sealing structure, which may include one or more of first coupling element 201, second coupling elements 202, first coupling portion 141, and second coupling portions 142, may also provide protection of the enclosed portable electronic device from being damaged by water, shock, dust, oil, mud, snow, vibration, spill, drop, impact, heat, frost, acid, chemical, corrosion, rain, sand, and/or other forms of intrusion. In some embodiments, seal strip 5 may be disposed within groove 14 and in contact with convex portion 20 when case structure 1000 is closed. In addition, seal strip 5 may also provide buffering or cushioning so that it may reduce or prevent the likelihood of damage at the coupling area of bottom cover 1 and/or first frame 2. In some embodiments, the material of the seal strip 5 may include silicone, rubber, thermoforming plastics, polyvinylchoride materials, polycarbonate, polyethylene terephthalate (PET), poly methyl methacrylate acrylic (PMMA), adhesive tape, and/or any material having similar characteristics. Seal strip 5 may be formed, for example, by a molding processing.
  • FIG. 1E illustrates a partial, perspective view showing the bottom side of case structure 1000 of FIG. 1A. Referring to FIGS. 1B and 1E, in some embodiments, a bottom side 21 of first frame 2 may include a first connection opening, such as an opening 22, a second connection opening, such as opening 23, and an opening 24. Opening 22 and opening 23 may be placed, for example, corresponding to the positions of an earphone jack and a charging and communication connector of the portable electronic device, respectively. Therefore, when the portable electronic device is accommodated, housed, or enclosed in case structure 1000, opening 22 and opening 23 may enable a user to operate the earphone function and the charging and communication functions of the portable electronic device without the need to remove the portable electronic device from case structure 1000. Bottom side 21 may also one or more audio holes (not shown) corresponding to the speaker and the microphone of the portable electronic device. The audio holes will be describes corresponding to FIG. 3E.
  • Referring to FIGS. 1B and 1E, in some embodiments, case structure 1000 may further include a resealable portion 6 configured to improve or enhance the waterproof or water-resistant capability of case structure 1000. For example, resealable portion 6 may be pivotally coupled to bottom side 21 of first frame 2 through an axis 26. In some embodiments, axis 26 may be placed, such as inserted into, in a base connector 25, which may be detachably or integrally attached to first frame 2 and/or second frame 4. As an example, base connector 25, such as a hinge, may be rotatably integrated with first frame 2 to form a single integral piece.
  • Referring to FIGS. 1B and 1E, resealable portion 6 may rotate toward first frame 2 and enclose bottom side 21. In some embodiments, resealable portion 6 may include a resealable cover 61 corresponding to opening 23. When resealable portion 6 is coupled to bottom side 21, resealable cover 61 may at least be partially plugged or inserted into; or may cover, opening 23, so that it enhances or improves the waterproof, water-resistant and/or the dust-resistant capability of case structure 1000.
  • Referring to FIGS. 1B and 1E, in some embodiments, resealable portion 6 may further include an opening 62 corresponding to opening 24 of first frame 2. For example, when resealable portion 6 is coupled to bottom side 21 of first frame 2, a securing mechanism 7 may be provided and configured to secure case structure 1000. In some embodiments, securing mechanism 7 may pass through opening 62, and couple to (or secure with) opening 24. As an example, securing mechanism 7 may be a screw having threads corresponding to the threads of opening 62 and/or opening 24, so that securing mechanism 7 may couple resealable portion 6 to bottom side 21 by the screw threads. Thus, securing mechanism 7 may be configured to enable or enhance the coupling of resealable portion 6 and first frame 2, thereby providing further waterproof or water-resistant capability of case structure 1000. One of ordinary skill in the art would appreciate that the exemplary securing structure that includes one or more of securing mechanism 7, resealable portion 6, and first frame 2 are for illustration purpose; and any other similar securing structures may be provided for securing case structure 1000. For example, in some embodiments, securing mechanism 7 may include no screw threads. Instead, by adjusting the relevant sizes of securing mechanism 7 and opening 24, securing mechanism 7 may be snugly or tightly attached or coupled to opening 24 without the need of screw threads. As another example, securing mechanism 7 may include magnetic coupling elements.
  • Referring to FIG. 1B, in some embodiments, at least a portion of film 3 may be disposed on or couple to first frame 2 and is configured to enable a user to view and operate an enclosed portable electronic device. In some embodiments, film 3 may include materials such as thermoforming plastics, polyvinylchoride materials, polycarbonate, polyethylene terephthalate (PET), poly methyl methacrylate acrylic (PMMA), adhesive tape, and/or any other materials having similar characteristics. Film 3 may be flexible but also may have an enhanced strength so that it may withstand water pressure under a higher water resistance standard. As an example, film 3 may be capable of withstanding a condition that is specified in the IPX7 standard, i.e., a water immersion for at least 30 minutes at a depth of at least 1 meter. Film 3 may also be capable of withstanding a condition of a higher IPX8 standard, i.e., a continual submersion in water under conditions which are identified by the manufacturer. As another example, film 3 may also be capable of withstanding the IP68 standard.
  • Film 3 may also be a clear/transparent or substantially clear/transparent water-resistant film so that a user can view the screen or a substantial portion of the screen of the portable electronic device. In addition, film 3 may also enable a user's operation of the portable electronic device when it is enclosed in case structure 1000. For example, some portable electronic devices may have capacitive-type touch sensors that are incorporated in the touch-point screens. A user may operate these portable electronic devices by touching and/or moving on the surface of the touch-point screen. Film 3 may thus be a touch-sensitive or transmissive film that enables the user to operate a touch-point screen of the portable electronic device through film 3. This may permit operations to be carried out without opening case structure 1000. In other words, film 3 may enable the portable electronic device to be operated when it is immersed under water or under other conditions that require the portable electronic device to be enclosed. One of ordinary skill in the art would appreciate that film 3 may also be other types of films that can enable operation of the portable electronic device, such as resistance-sensitive films.
  • In some embodiments, film 3 may also be an anti-reflection film, an anti-glare film, an anti-fingerprint film, a monitor filtering film, etc. For example, film 3 may filter out the light reflected from the smooth glass surface of the touchscreen device as well as the radiation emitted from the portable electronic device. This may be used to protect the user privacy by decreasing the viewing angle of the screen of the portable electronic device. In addition, film 3 may also be able to dissipate static electrical charge buildup. Film 3 may also be polarized, colorized, or tinted, depending on the application.
  • A portable electronic device may have buttons or switches, such as the “home” button on an Apple iPhone 5® device. Therefore, in some embodiments, film 3 may include a corresponding convex or concave shape to enable convenient operation of the portable electronic device. As an example, for an Apple iPhone® 5 device, film 3 may include a concave circle near the bottom edge (not shown) for operating of the “home” button. One of ordinary skill in the art would appreciate that the concave circle may be positioned anywhere on film 3. In addition, film 3 may include any number of shapes, buttons, membranes, etc., which may enable convenient operation of the portable electronic device.
  • Referring to FIG. 1B, in some embodiments, film 3 may be detachably or integrally coupled to a flat part of first frame 2 and/or second frame 4 through an attaching mechanism, such as a seal 8 shown in FIG. 1B. For example, seal 8 may be directly disposed on the flat part of first frame 2, such as the top side of first frame 2. Seal 8 may include a very high bond (VHB) material. Seal 8 may also include any colloidal substances or materials, and double-sided adhesives. Seal 8 may also be formed by coating any colloidal substances onto the flat part of first frame 2 to provide the adhesive effect. Moreover, seal 8 may include an adhesive material that is waterproof up to, for example, one meter below the water surface. In some embodiments, when adhesive materials are used, film 3 may not be replaceable. That is, replacing film 3 may cause damage to film 3 and render it non-useable. Thus, in these embodiments, film 3 may be made of or combined with strength enhancing, anti-scratch or anti-breaking material, so that damage to film 3 can be reduced or eliminated. Film 3 may thus have a longer life span. In some other embodiments, seal 8 may allow film 3 to be replaced if it is scratched or damaged. Film 3 in these embodiments may have a shorter life span but may be relatively inexpensive. In addition, seal 8 may also be configured to be impact-absorbing so that it may prevent or reduce the likelihood of damage caused by impact, impinge, shock, and/or drop that are imposed at the second frame and/or film 3 of case structure 1000.
  • Referring to FIG. 1B, in some embodiments, second frame 4 may be hingedly, rotatably, movably, permanently, detachably, latchably, adhesively, integrally, and/or snugly coupled to first frame 2. In addition, second frame 4, and the intervening first frame 2, may also be detachably coupled to bottom cover 1 through, for example, a coupling structure. In some embodiments, to provide or enhance the waterproof or water-resistant capability, second frame 4 may further include a plurality of (such as two) engaging portions 41 configured to secure second frame 4 to bottom cover 1 through a plurality of (such as two) coupling structures 15 of bottom cover 1. For example, the plurality of engaging portions 41 may be holes or openings that have same or similar dimension as the plurality of coupling structures 15, such as protrusions. The holes and protrusions may enable second frame 4 to be snugly coupled to bottom cover 1 and thereby form a secured coupling to prevent or reduce the likelihood of undesirable separating of case structure 1000. Therefore, when case structure 1000 is secured, it may be provided with additional waterproof and water-resistant capability. One of ordinary skill in the art would appreciate that positions of coupling structures 15 and engaging portions 41 shown in FIG. 1B are for illustration purpose and are not limiting. For example, coupling structures 15 and engaging portions 41 may be placed in external edges of case structure 1000. Coupling structures 15 may be attached to engaging portions 41 by any means, such as by one or more latch that may be located at the external edges of bottom cover 1.
  • Referring to FIG. 1B, in some embodiments, second frame 4 may further include a plurality of casing buttons, such as casing buttons 42, 43, and 44. Casing buttons 42, 43, and 44 may be depressible and may be configured to operate their respective underlying functioning mechanisms, such as a push button, a key, a switch, a sliding control, a knob, or any other control mechanism, of the portable electronic device. As an example, the material of casing button 42 may include soft plastic, such as polypropylene, soft rubber, and/or any other materials having similar characteristics.
  • Referring to FIG. 1B, in some embodiments, casing button 42 may include an axis 421. When case structure 1000 is closed or assembled, for example, casing button 42 may be detachably, movably, or permanently coupled to or disposed in an opening 27 through axis 421. Axis 421 may enable coupling of casing button 42 in a manner that may allow casing button 42 to switch, move, slide, tilt, and/or perform other similar motions. As an example, axis 421 may include a rotational axis and may be housed, coupled, or gripped in a concave portion, slot, groove, and/or other similar structures (not shown) in second frame 4. In some embodiments, such structure may enable casing button 42 to engage in a motion as described above to, for example, turn on and off a functional button of the enclosed portable electronic device. In some embodiments, such structure may itself move, slide, tilt, and/or perform other similar motions to, for example, turn on and off a functional button of the enclosed portable electronic device.
  • Referring to FIG. 1B, in some embodiments, casing buttons 43 and 44 may be detachably, movably, and/or permanently coupled to or placed in openings 28 and 29 of first frame 2, respectively. In some embodiments, when case structure 1000 encloses a portable electronic device, such as an Apple iPhone® 5 device, openings 27, 28, and 29 may correspond to the ring/mute switch button, the volume button, and the power button of the portable electronic device, respectively. Therefore, a user may operate the functional buttons of the portable electronic device (not shown) by, for example, pressing on casing buttons 42, 43, and 44 of case structure 1000. One of ordinary skill in the art would appreciate that case structure 1000 may also include any number of openings and casing buttons corresponding to the underlying functioning mechanisms. The openings may be located, disposed, placed, or arranged at any part of case structure 100 as desired.
  • Referring to FIGS. 1B and 1E, second frame 4 may further include a connector 45, such as a band, a string, a rope, or a connector having similar characteristics. In some embodiments, connector 45 may be flexible and configured to enable, for example, bending and/or stretching. As shown in FIGS. 1B and 1E, connector 45 may include a plurality of (such as three) openings, holes, or perforations (collectively as perforation 451) that are configured to enable a flexible connection of a cap 9. For example, perforations 451 of the connector 45 may enable cap 9 to be easily plugged or inserted into opening 22. One of ordinary skill in the art would appreciate that the number of perforations 451 is not limited to three as shown in FIGS. 1B and 1E, and may be any number that is desired. Moreover, connector 45 may also prevent or reduce the likelihood of undesired separation of cap 9 from case structure 1000. As an example, connector 45 may be coupled to cap 9 in a manner that may prevent cap 9 from being misplaced such that cap 9 can be easily located and plugged into opening 22 when desired. Furthermore, one of ordinary skill in the art would appreciate that cap 9 and connector 45 may be two separate elements or may be an integral single piece.
  • Referring to FIG. 1E, cap 9 may include a first body 91 and a second body 92. First body 91 may have a shape corresponding to that of opening 22, such as an opening corresponding to an earphone jack, and may thus snugly plug into opening 22 for water-sealing opening 22 and provide additional waterproof and/or water-resistance capability to case structure 1000. Second body 92 may include a hand-operable portion that is detachably and/or rotatably coupled to connector 45 as shown in FIG. 1E. In some embodiments, a user may attach cap 9 to opening 22 by, for example, rotating the hand-operable portion of second body 92 so that cap 9 may be, for example, screwed into a threaded opening 22.
  • FIG. 1F illustrates a partial, exploded view showing case structure 1000 of FIG. 1A. Referring to FIGS. 1B and 1F, FIG. 1F shows a partial structure of bottom cover 1 and first frame 2. In some embodiments, bottom cover 1 may further include a lens protecting structure 16, which may include a base 160, a first structural element 161, a second structural element 162, a first lens 163, and a second lens 164. First structural element 161 may be directly coupled to base 160. First lens 163 and second lens 164 may be disposed in the two holes or openings of the first structural element 161. Moreover, second structural element 162 may include a plurality of holes or openings for coupling, attaching, or assembling with a corresponding plurality of multiple microstructures of base 160. As an example, when the plurality of multiple microstructures are snugly inserted or coupled into the plurality of holes or openings, lens protecting structure 16 may be closed.
  • Referring to FIG. 1F, in some embodiments, first lens 163 and second lens 164 of lens protecting structure 16 may correspond to the camera lens and the flash lens of the portable electronic device. Moreover, at least one of first lens 163 and second lens 164 may include double anti-reflective coating for providing a high transparency feature, thereby enabling first lens 163 and second lens 164 to be anti-reflective. Anti-reflective coating may enable, for example, the portable electronic device to obtain improved picturing effect and result. One of ordinary skill in the art would appreciate that first lens 163 and second lens 164 may also have any other coating desired, such as anti-glare and anti-scratch coatings.
  • FIG. 2A illustrates an exploded view showing the bottom cover of case structure 1000 of FIG. 1A, with the bottom cover of case structure 1000 being capable of coupling to an exemplary cap 132. Referring to FIG. 2A, bottom cover 1 may include a mounting structure 12 and cap 132 on the opposing side of housing 11. Mounting structure 12 may enable a mounting or coupling of various external objects to case structure 1000, as a user may desire or as a circumstance may require. In some embodiments, cap 132 may be detachably coupled to mounting structure 12. The structure of mounting structure 12 will be explained as following, and details of the mounting mechanism will be described later.
  • Referring to FIG. 2A, in some embodiments, mounting structure 12 may have a circular-shaped structure with one or more grooves, slots, hooks, protrusions, etc. As an example, mounting structure 12 may include a plurality of (such as three as shown in FIG. 2A) engaging elements 121, such as protrusions, edges, slots, hooks, grooves, etc., that are configured to engage, couple, and/or secure cap 132 to mounting structure 12. The plurality of engaging elements 121 may be separated with, for example, at least one space, slot, or gap. The space, slot, or gap between any two adjacent engaging elements 121 may form a plurality (such as three shown in FIG. 2A) of engaging slots 122. Engaging slots 122 between adjacent engaging elements 121 may have any size that is desired, and may or may not have the same size as one another. Correspondingly, cap 132 may include a plurality of (such as three) engaging elements 131. In some embodiments, the structure and/or shape of second engaging element 131 may be substantially the same or similar to that of engaging elements 121 and/or engaging slots 122. In some embodiments, the length of engaging elements 131 may be substantially the same as or smaller than engaging slots 122.
  • Referring to FIG. 2A, in some embodiments, cap 132 may be rotatably and detachably coupled to mounting structure 12 by inserting cap 132 into mounting structure 12 and rotating it with respect to mounting structure 12 of bottom cover 1. As an example, cap 132 may be inserted into mounting structure 12 by aligning engaging elements 131 with engaging slots 122. When cap 132 is inserted into mounting structure 12, it may rotate a certain degree clockwise or counterclockwise with respect to mounting structure 12. In some embodiments, the protrusions of engaging elements 121 may include an end portion that is configured to stop cap 132 from rotating and therefore enabling cap 132 to be engaged, coupled, or secured to mounting structure 12.
  • Referring to FIG. 2A, in some embodiments, when cap 132 is coupled to mounting structure 12, engaging elements 131, as shown in FIG. 2A, may operatively engage or couple to respective engaging elements 121, thereby securing cap 132 to mounting structure 12. When cap 132 is secured to mounting structure 12, it may also provide protection of the enclosed portable electronic device from being damaged by water, shock, dust, oil, mud, snow, vibration, spill, drop, impact, heat, frost, acid, chemical, corrosion, rain, sand, and/or other forms of intrusion. Moreover, in some embodiments, at least one of cap 132 and mounting structure 12 may also include water-sealing ring or other sealing mechanisms. One of ordinary skill in the art would appreciate that the above-described mounting structure and its elements (such as engaging elements 121 and 131) are for illustration purposes and should not be construed to limit the scope of the mounting structure.
  • Referring to FIG. 2A, the protrusion of engaging elements 121 may also include a surface portion that may prevent or substantially reduce the likelihood of undesirable disengaging or detaching of cap 132 from mounting structure 12. As an example, the surface portion of one or both engaging elements 121 and 131 may include at least one of a pattern, a surface texture, an engraving, a monogram, and an embossment, for providing additional grip, so that cap 132 may not unexpectedly rotate with respect to mounting structure 12 and separate from it.
  • FIG. 2B illustrates a perspective view showing case structure 1000 of the FIG. 2B attached or coupled to an exemplary mounting adaptor 502. FIG. 2C illustrates a perspective view of case structure 1000 detached from mounting adaptor 502 of FIG. 2B. Referring to the FIGS. 2B and 2C, in some embodiments, mounting adaptor 502 may include an adaptive structure 504 and an engaging body 506 corresponding to mounting structure 12. Adaptive structure 504 will be described below in connection with FIG. 2D. Engaging body 506 may also include a plurality of engaging elements that are substantially the same as or similar to engaging elements 131 of cap 132 shown in FIG. 2A. Therefore, the mechanism of mounting or coupling engaging body 506 to mounting structure 12 may be also substantially the same or similar to that described corresponding to FIG. 2A and thus will not be described here.
  • FIG. 2D illustrates a perspective view showing an exemplary coupling of case structure 1000 of FIG. 2A to an exemplary object, such as an external mounting object 700, through the mounting adaptor 502. Referring to FIGS. 2B, 2C, and 2D, in some embodiments, adaptive structure 504 of mounting adaptor 502 may be configured to enable freedom of movement of mounting adaptor 502 with respect to external mounting object 700. For example, adaptive structure 504 may be of a ball-shape, so that it may be snugly fit into external mounting object 700 and enable adaptive structure 504 to be adaptively, hingedly, rotatably, movably, permanently, detachably, latchably, and/or snugly coupled to external mounting object 700.
  • Referring to FIG. 2D, in some embodiments, external mounting object 700 may include a housing space 704 and a mounting body 702. Housing space 704 may include a notch-structure corresponding to adaptive structure 504. As shown in FIG. 2D, in some embodiments, adaptive structure 504 enables mounting adaptor 502 to be coupled to both case structure 1000 and external mounting object 700. As an example, case structure 1000 may be coupled or attached to mounting adaptor 502 through mounting structure 12, and mounting adaptor 502 may be movably or rotatably coupled to external mounting object 700 through adaptive structure 504. In addition, external mounting object 700 may further attach to a surface or another object (not shown) through a mounting body 702. As an example, mounting body 702 may include a suction disc with suction capability, thereby enabling coupling of mounting body 702 (together with mounting adaptor 502 and case structure 1000) to, for example, a table, a glass surface of a car, or any other surface. The object to which mounting body 702 couples or attaches may or may not be a flat surface. One of ordinary skill in the art would appreciate that the attaching of mounting body 702 to an object can include any mechanism desired and is not limited to that shown in FIG. 2D. In some embodiments, when case structure 1000 is coupled to an object (not shown) through mounting adaptor 502 and external mounting object 700, a user may be enabled to operate the enclosed portable electronic device without having to hold the device. In addition, one or both external mounting object 700 and mounting adaptor 502 may also provide cushioning or vibration reduction, thereby preventing or reducing the likelihood of damage via vibration, shaking, etc., of the portable electronic devices and/or case structure 1000.
  • Referring to FIG. 2D, in some embodiments, an upper portion of mounting adaptor 502 (not including adaptive structure 504) may itself be adaptively, hingedly, rotatably, movably, permanently, detachably, latchably, and/or snugly adapted or coupled to adaptive structure 504, thereby adding another degree of freedom. For example, the upper portion of mounting adaptor 502 may be coupled to adaptive structure 504 in such a manner that it can move a substantial degree with respect to adaptive structure 504, therefore enabling tilting and/or rotating of case structure 1000 with respect to adaptive structure 504.
  • Referring to FIG. 2D, in some embodiments, adaptive structure 504 of mounting adaptor 502 may be detachably or removably secured to external mounting object 700. As a result, a user may conveniently detach or separate case structure 1000 and/or mounting adaptor 502 from an external object without having to remove external mounting object 700 from the external object to which it is attached. In other words, the detachability or removability of mounting adaptor 502 from external mounting object 700 enables easy mounting, detaching, and carrying of case structure 1000 and the enclosed portable electronic device. Furthermore, in some embodiments, because a user may easily detach or separate mounting adaptor 502 from external mounting object 700 and does not need to carry external mounting object 700, the material and design of external mounting object 700 may be enhanced and/or strengthened. For example, external mounting object 700 may be strengthened by using heavier and/or robust materials or by designing with additional features. The weight of external mounting object 700 therefore may be of a less concern because a user may not need to carry it.
  • One of ordinary skill in the art would appreciate that the mounting structure is not limited to those shown in FIGS. 2C and 2D, and may include any desired structure. For example, a mounting structure may enable the mounting of a detachable handle, instead of mounting adaptor 502, to case structure 1000. In some exemplary embodiments, the mounting structure may include a hand-operable screw, instead of engaging elements 121 and 131 shown in FIG. 2A. For example, bottom cover 1 may include a mounting point, and by fastening a hand-operateable screw using a screw cap, a mounting body of a detachable handle may be attached to bottom cover 1 through the mounting point. The attachment may enable manipulation of case structure 1000 through the detachable handle. The mounting point of bottom cover 1, for example, may be a screw hole having a thread that is compatible with a standard camera tripod having a connection including, for example, ¼-20 UNC threads. Thus, a tripod or any other handling or supporting structures that have a tripod-compatible screw may be connected or coupled to case structure 1000.
  • In some embodiments, the mounting of a detachable handle may use a magnetic mounting mechanism. For example, bottom cover 1 may include at least one of a permanent magnet and a ferromagnetic material. The magnets may be composed of NdFeB, NIB, or Neo. An external mounting object may also include magnets or otherwise be configured to have magnetic properties so it can be magnetically coupled to bottom cover 1 in a substantially secure manner, in order to prevent unintended detachment by gravity, by vibration, or by the force of a user's operation of the portable electronic device enclosed in case structure 1000. The strength of the magnetic field of bottom cover 1 or the external mounting object, however, may be controlled so that it does not affect or substantially affect the operation of the portable electronic device. In addition, magnetic shielding materials may be included in bottom cover 1 to prevent the magnetic field from interfering with the electronic device. For example, a layer of sheet metal, metal screen, or metal foam may be included in bottom cover 1. A layer of metallic ink or similar material may also be coated inside bottom cover 1 to provide the shielding. Further, one of ordinary skill in the art would appreciate that a mounting adaptor, a detachable handle, or an external mounting object may be mounted to case structure 1000 by any type of mounting mechanism that is desired.
  • FIG. 3A illustrates a perspective view of an exemplary case structure 2000. FIG. 3B illustrates an exploded view of case structure 2000 of FIG. 3A. Referring to FIGS. 3A and 3B, case structure 2000 is provided for housing or enclosing a portable electronic device (not shown), such as an Apple iPad® or iPad® mini device, and is configured to prevent or reduce the likelihood of shock/drop/impact-, water-, dust-, and/or chemical-damage of the portable electronic device. Case structure 2000 may be substantially waterproof, such as waterproof in compliance with class IP68 according to the U.S. National Electrical Manufacturers Association rating. The types of portable electronic devices that are capable of being enclosed in case structure 2000 may include, but are not limited to, a cell phone, a smart phone, an MP3 player, a portable computer, and a tablet PC, a personal digital assistant, and/or other similar portable electronic devices.
  • Referring to FIGS. 3A and 3B, according to some embodiments, case structure 2000 may include bottom cover 1, film 3, first frame 2, and second frame 4. In some embodiments, bottom cover 1 may include a first bottom cover 1 a and a second bottom cover 1 b. Second frame 4 may be detachably coupled to or integrated with first frame 2 so as to form a single piece. And second bottom cover 1 b may be detachably coupled to or integrated with first bottom cover 1 a. Film 3 may be coupled to one or both first bottom cover 1 a and first frame 2, and be placed between the two. In some embodiments, first bottom cover 1 a may be detachably coupled to or integrated with first frame 2. The dimensions and aspect ratios of second bottom cover 1 b, first frame 2, and second frame 4 may be substantially the same. The dimensions of first bottom cover 1 a may be substantially or slightly smaller than those of second bottom cover 1 b, first frame 2, and second frame 4, so that it may be coupled to or accommodated by second bottom cover 1 b, bottom cover 1, and second frame 4. Referring to FIG. 3A, case structure 2000 is illustrated in an assembled condition, and thus, some elements of case structure 2000 may not be marked or labeled in FIG. 3A.
  • The materials of case structure 2000 may include, for example, polypropylene (PP), polycarbonate (PC), or thermoplastic polyurethane (TPU), or any other material having similar characteristics. As an example, in some embodiments, the material of first bottom cover 1 a may include PC; the material of second bottom cover 1 b may include TPU; the material of first frame 2 may include PC; and the material of second frame 4 may include TPU. In addition, second bottom cover 1 b can be manufactured by a double-injection manufacturing process. One of ordinary skill in the art would appreciate that the material of each element of the case structure 2000 may not be limited to those described above and may include any other material desired. For example, the material of some elements of case structure 2000 may include metal, alloy, stainless steels, nylons, hard plastics, iron, aluminum, lead, and/or other materials having similar characteristics.
  • FIG. 3C illustrates a partial, cross-sectional view of case structure 2000 of FIG. 3A. FIG. 3D illustrates a partial, enlarged cross-sectional view of case structure 2000 of FIG. 3A. Referring to FIGS. 3B, 3C, and 3D, first bottom cover 1 a may include housing 11. In some embodiments, housing 11 may include a flat structure, such as a flat bed, for accommodating or housing a portable electronic device, such as an Apple® iPad mini device. The dimensions of housing 11 may correspond to the structure and/or dimensions of the portable electronic device housed therein, and may not be limited to those shown in FIGS. 3B-3D. In some embodiments, first bottom cover 1 a may include groove 14 surrounding at least a portion of the periphery of housing 11. Groove 14 may be formed by, for example, water barrier 13 and the internal peripheral portion of first bottom cover 1 a. In some embodiments, first frame 2 may have a convex portion 20 corresponding to groove 14. When case structure 2000 is closed, convex portion 20 of first frame 2 may be partially or entirely inserted or disposed in groove 14. One of ordinary skill in the art would appreciate that groove 14 may be included in other places. As an example, in some embodiments, groove 14 may be included in first frame 2 or second frame 4. Correspondingly, in these embodiments, convex portion 20 may be included in the opposing frame or cover, such as first bottom cover 1 a.
  • Referring to FIGS. 3C and 3D, in some embodiments, groove 14 may include first coupling portion 141 on the side that is further away from housing 11. For example, first coupling portion 141 may be included in the peripheral of first bottom cover 1 a. Groove 14 may also include a plurality of second coupling portions 142 on the side that is close to or near housing 11. For example, second coupling portions 142 may be included in water barrier 13. In some embodiments, second coupling portions 142 may be separately or discontinuously disposed between groove 14 and accommodating or housing 11, such as disposed in water barrier 13.
  • Referring to FIGS. 3C and 3D, in some embodiments, convex portion 20 of first frame 2 may include at least one first coupling element 201 and a plurality of second coupling elements 202, corresponding to first coupling portion 141 and second coupling portions 142, respectively. In some embodiments, when case structure 2000 is closed, and therefore convex portion 20 is in contact with or inserted into groove 14, first coupling element 201 and second coupling elements 202 may be hingedly, rotatably, movably, permanently, detachably, latchably, and/or snugly coupled or engaged with first coupling portion 141 and second coupling portions 142, respectively. First coupling element 201, second coupling elements 202, first coupling portion 141, and second coupling portions 142, may thus form of a water-sealing or water-resistant structure configured to provide water-resistant or waterproof capability to case structure 2000. As an example, first coupling portion 141 and first coupling element 201 may each include a protrusion that may be engaged with each other to form a tight coupling. As another example, second coupling elements 202 may include a plurality of separated protrusions so that they may be engaged with a corresponding plurality of second coupling portions 142, such as a plurality of slots or small openings. Moreover, in some embodiments, the protrusions of second coupling elements 202 may be semi-circle shaped structures, so that a user may be provided with a smoother and more convenient experience for attaching and/or detaching of case structure 2000. One of ordinary skill in the art would appreciate that for forming a water-sealing or water-resistant structure, some but not all first coupling element 201, second coupling elements 202, first coupling portion 141, and second coupling portions 142 may be needed.
  • Referring to FIGS. 3C and 3D, water barrier 13 may further include a plurality of protrusions 162 configured to enhance the strength of water barrier 13. As an example, FIGS. 3C and 3D illustrate that the plurality of protrusion 162 may include one or more curved fins configured to provide additional support and structural strength to water barrier 13, so that likelihood of breaking, distorting, fracturing, chipping, bending, and/or other similar damage may be prevented or reduced.
  • Referring to FIGS. 3B-3D, case structure 2000 may include a seal strip 5 configured to provide additional water-sealing or water-resistance capability of the water-sealing or water-resistant structure that includes groove 14 and convex portion 20. Additionally, seal strip 5 and the water-sealing structure, which may include first coupling element 201, second coupling elements 202, first coupling portion 141, and second coupling portions 142, may also provide protection of the enclosed portable electronic device from being damaged by water, shock, dust, oil, mud, snow, vibration, spill, drop, impact, heat, frost, acid, chemical, corrosion, rain, sand, and/or other forms of intrusion. In some embodiments, seal strip 5 may be disposed within groove 14 and in contact with convex portion 20 when case structure 2000 is closed. In addition, seal strip 5 may also provide buffering or cushioning so that it reduces or prevents the likelihood of damage at the coupling area of first bottom cover 1 a and/or first frame 2. In some embodiments, the material of the seal strip 5 may include silicone, rubber, thermoforming plastics, polyvinylchoride materials, polycarbonate, polyethylene terephthalate (PET), poly methyl methacrylate acrylic (PMMA), adhesive tape, and/or any material having similar characteristics. Seal strip 5 may be formed, for example, by a molding processing.
  • FIG. 3E illustrates a partial, exploded view of case structure 2000 of FIG. 3A. Referring to FIGS. 3B and 3E, in some embodiments, first bottom cover 1 a may include a plurality of, such as two, recess portions 74. Correspondingly, a bottom side 21 of first frame 2 may include a plurality of, such as two, openings 22 a. Openings 22 a may be located, for example, corresponding to the positions of the speaker and the microphone of the portable electronic device, and may also be referred to as audio holes. Therefore, when the portable electronic device is accommodated, housed, or enclosed in case structure 2000, recess portions 74 may align with the corresponding openings 22 a, and thus enable a user to operate the speaker and the microphone functions without the need to remove the portable electronic device from case structure 2000. Furthermore, openings 22 a, or the audio holes, may also include a waterproof or water-resistant, but sound transmissive film (not shown), so that the impact of sound transmitting quality through the openings 22 a may be reduced while the portable electronic device may still be protected from water damage.
  • Referring to FIG. 3E, in some embodiments, first bottom cover 1 a may further include openings 22 and 23. Opening 22 and opening 23 may be placed, for example, corresponding to the positions of an earphone jack and a charging and communication connector of the portable electronic device, respectively. Therefore, when the portable electronic device is accommodated, housed, or enclosed in case structure 2000, opening 22 and opening 23 may enable a user to operate the earphone function and charging and communication functions of the portable electronic device without the need to remove the portable electronic device from case structure 2000.
  • Referring to FIGS. 3B and 3E, second bottom cover 1 b may be configured to cover first bottom cover 1 a. For example, second bottom cover 1 b and first bottom cover 1 a may be coupled to or assembled snugly or tightly through coupling structures, such as one or more microstructures. In some embodiments, first bottom cover 1 a may include a plurality of, such as three, securing portions 101 placed, for example, at the corners of first bottom cover 1 a. Securing portions 101 may be placed corresponding to a plurality of, such as three, openings 56 of second bottom cover 1 b. Referring to FIG. 3E, in some embodiments, first bottom cover 1 a and second bottom cover 1 b may be hingedly, rotatably, movably, permanently, detachably, latchably, screwingly, and/or snugly coupled or attached to each other by, for example, coupling securing mechanisms 72 to securing portions 101 through openings 56. As an example, securing portions 101 may include threaded screw holes corresponding to threaded securing mechanisms 72, such as screws. Thus, securing mechanisms 72 may be coupled to or attached to securing portions 101 by the screw threads. One of ordinary skill in the art would appreciate that positions of securing mechanisms 72, openings 56, or securing portions 101 shown in FIGS. 3B and 3E are for illustration purpose and are not limiting. Furthermore, securing mechanism 72 may be attached to securing portions 101 by any means, such as by one or more latch that may be located at the external edges of first or second bottom covers 1 a or 1 b.
  • Referring to FIGS. 3B and 3E, in some embodiments, second bottom cover 1 b may further include a cap 51 corresponding to opening 23. Cap 51 may be configured to be resealable to prevent or reduce the likelihood of water damage. For example, cap 51 may include a resealable cover and/or a seal strip. When the charging or communication function of the portable electronic device is not used, the resealable cover and/or the seal strip of cap 51 may at least be partially plugged or inserted into opening 23 so that it enhances or improves the waterproof, water-resistant and/or the dust-resistant capability of case structure 2000. In some embodiments, cap 51 may be integrated with second bottom cover 1 b and thus form a single piece.
  • Referring to FIGS. 3B and 3E, in some embodiments, cap 51 and opening 23 may be configured to correspond in dimension and/or shape with respect to each other so that the two may be secured snugly or tightly. In some embodiments, cap 51 may be configured with a different dimension and/or shape so that it may include, for example, a screw thread that enables a screwing mechanism (not shown) configured to secure cap 51 with opening 23.
  • Referring to FIGS. 3B and 3E, in some embodiments, second bottom cover 1 b may include a plurality of casing buttons, such as casing buttons 42, 52, and 53. Casing buttons 42, 52, and 53 may be depressible for operating the underlying functioning mechanisms, such as push buttons, keys, switches, sliding controls, knobs, or other control mechanisms, of the portable electronic device. As a non-limiting example, the material of casing button 52 include soft plastic, such as polypropylene, soft rubber, and/or any other materials having similar characteristics.
  • Referring to FIGS. 3B and 3E, in some embodiments, when case structure 2000 is closed or assembled, for example, casing buttons 52 and 53 may be detachably, movably, or permanently coupled to or disposed in openings 17 and 18 of first bottom cover 1 a, respectively. In some embodiments, when case structure 2000 encloses a portable electronic device, openings 17 and 18, and respective casing buttons 52 and 53, may correspond to, for example, the power button and the volume up/down button of the portable electronic device, respectively. Casing button 42 may correspond to, for example, the ring/mute button of the portable electronic device. One of ordinary skill in the art would appreciate that case structure 2000 may also include any number of openings corresponding to the underlying functioning mechanisms. The openings may be placed, disposed, or arranged at any locations desired. Referring to FIGS. 3B and 3E, in some embodiments, a user may operate the buttons of the portable electronic device (not shown) by, for example, pressing on casing buttons 42, 52, and 53 of case structure 2000, without having to remove the portable electronic device from case structure 2000.
  • Referring to FIG. 3B, in some embodiments, at least a portion of film 3 may be coupled to first frame 2 and may be configured to enable a user to view and operate an enclosed portable electronic device. In some exemplary embodiments, film 3 may include materials such as thermoforming plastics, polyvinylchoride materials, polycarbonate, polyethylene terephthalate (PET), poly methyl methacrylate acrylic (PMMA), adhesive tape, and/or any other materials having similar characteristics. Film 3 may be flexible but also may have an enhanced strength so that it may withstand a water pressure under a higher water resistance standard. As an example, film 3 may be capable of withstanding a condition that is specified in the IPX7 standard, i.e., a water immersion for at least 30 minutes at a depth of at least one meter. Film 3 may also be capable of withstanding a condition of a higher IPX8 standard, i.e., a continual submersion in water under conditions which are identified by the manufacturer. As another example, film 3 may also be capable of withstanding the IP65 standard.
  • Film 3 may also be a clear/transparent or substantially clear/transparent water-resistant film so that a user can view the screen or a substantial portion of the screen of the portable electronic device. In addition, film 3 may also enable a user's operation of the portable electronic device when it is enclosed in case structure 2000. For example, some portable electronic devices may have capacitive-type touch sensors that are incorporated in the touch-point screens. A user may operate these portable electronic devices by touching and/or moving a fingertip on the surface of the touch-point screen. Film 3 may thus be a touch-sensitive or transmissive film that enables the user to operate a touch-point screen of the portable electronic device through film 3. As a result, operations may be carried out without opening case structure 2000. In other words, film 3 may enable the portable electronic device to be operated when it is immersed under water or under other conditions that require the portable electronic device to be enclosed in case structure 2000. One of ordinary skill in the art would appreciate that film 3 may also be other types of films that can enable operation of the portable electronic device, such as resistance-sensitive films.
  • In some embodiments, film 3 may also be an anti-reflection film, an anti-glare film, an anti-fingerprint film, a monitor filtering film, and/or other similar films. For example, film 3 may filter out the light reflected from the smooth glass surface of the touchscreen device as well as the radiation emitted from the portable electronic device. This may be used to protect the user's privacy by decreasing the viewing angle of the touchscreen of the portable electronic device. In addition, film 3 may also be able to dissipate static electrical charge buildup. Film 3 may also be polarized, colorized, or tinted, depending on the application.
  • A portable electronic device may have buttons or switches, such as the “home” button on an Apple iPad® mini device. Therefore, in some exemplary embodiments, film 3 may include a corresponding convex or concave shape to enable convenient operation of the portable electronic device. As an example, for an Apple iPad® mini device, film 3 may include a concave circle near the bottom edge (not shown) for operating of the “home” button. One of ordinary skill in the art would appreciate that the concave circle may be positioned anywhere on film 3. In addition, film 3 may include any number of shapes, buttons, membranes, etc., which may enable ease of operation of the portable electronic device.
  • Referring to FIGS. 3B-3D, in some embodiments, film 3 may be detachably or integrally coupled to a flat part of first frame 2 and/or second frame 4 through an attaching mechanism, such as an seal 8 shown in FIG. 3B. For example, seal 8 may be directly disposed on the flat part, such as a lower surface, of first frame 2. Seal 8 may include a VHB material. Seal 8 may also include any colloidal substances or materials, and double-sided adhesives. Seal 8 may also be formed by coating any colloidal substances on the flat part of first frame 2 to provide the adhesion effect. Moreover, seal 8 may include an adhesive material that is waterproof up to, for example, one meter below the water surface. In some embodiments, when the adhesive materials are used, film 3 may not be replaceable. That is, replacing film 3 may cause damage to film 3 and render it non-useable. Thus, in these embodiments, film 3 may be made of or combined with strength enhancing, anti-scratch or anti-breaking material, so that damage to film 3 can be reduced or eliminated. Film 3 may thus have a longer life span. In some other embodiments, seal 8 may allow film 3 to be replaced if it is scratched or damaged. Film 3 in these embodiments may have a shorter life span but may be relatively inexpensive. In addition, seal 8 may also be configured to be impact-absorbing so that it may prevent or reduce the likelihood of damage caused by impact, impinge, shock, and/or drop that are imposed at the second frame and/or film 3 of case structure 2000.
  • Referring to FIG. 3B, in some embodiments, case structure 2000 may include second frame 4, which may be hingedly, rotatably, movably, permanently, detachably, latchably, adhesively, and/or snugly coupled to first frame 2. In addition, second frame 4, and the intervening first frame 2, may also be detachably coupled to first bottom cover 1 a and/or second bottom cover 1 b through, for example, a coupling structure. In some embodiments, to provide or enhance the waterproof or water-resistant capability, second frame 4 may further include one or more engaging portions 41 configured to secure second frame 4 to first frame 2. For example, when a user press on an engaging portion 41, second frame 4 may be snugly or tightly coupled to first frame 2, thereby forming a secured coupling to prevent or reduce the likelihood of undesired separation of case structure 2000. In some embodiments, engaging portion 41 may also enable a user to separate or dissemble case structure 2000 when desired. For example, when a user pulls engaging portion 41 (and together the second frame 4) away from first frame 2, second frame 4 may be conveniently separated or released from first frame 2 and/or first bottom cover 1 a.
  • Referring to FIGS. 3B and 3E, case structure 2000 may further include cap 9. Cap 9 may include a first body 91 and a second body 92. First body 91 may have a shape corresponding to that of opening 22, such as an opening corresponding to an earphone jack, and may thus snugly plug into opening 22 to provide additional waterproof and/or water-resistance capability to case structure 2000. Second body 92 may include a hand-operable portion that is coupled to first body 91. In some embodiments, a user may attach cap 9 to opening 22 by, for example, rotating the hand-operable portion of second body 92 so that cap 9 may be, for example, screwed into a threaded opening 22.
  • Referring to FIGS. 3B and 3E, second bottom cover 1 b may further include a lens protecting structure 54, which may include a base 540 and a lens 541. Lens 541 may be coupled to or placed in base 540. Additionally, first bottom cover 1 a may include an opening 19 corresponding to lens protecting structure 54. Opening 19 may be configured to encompass the whole area of lens protecting structure 54, thereby enabling, for example, a camera function of the portable electronic device to be operated without the need to remove the portable electronic device from case structure 2000.
  • Referring to FIGS. 3B and 3E, lens 541 of lens protecting structure 54 may correspond to the camera lens of the portable electronic device. Moreover, lens 541 may include a double anti-reflective coating to obtain the high-transparency feature, and thereby enabling lens 541 to be anti-reflective. Anti-reflective coating may enable, for example, the portable electronic device to obtain improved picturing effect and result. One of ordinary skill in the art would appreciate that lens 541 may also have any other coating desired, such as anti-glare and anti-scratch coatings
  • FIG. 4A illustrates an exploded view showing first bottom cover 1 a of case structure 2000 of FIG. 3A, with first bottom cover 1 a of the case structure being capable of coupling to cap 132. For example, first bottom cover 1 a may include mounting structure 12 configured to couple to cap 132, mounting adaptor 502, or any other objects. FIG. 4B illustrates a perspective view showing case structure 2000 of FIG. 3A attached or coupled to mounting adaptor 502. FIG. 4C illustrates a perspective view of case structure 2000 detached from mounting adaptor 502 of FIG. 3A. FIG. 4D illustrates a perspective view showing an exemplary coupling of case structure 2000 of FIG. 4A to external mounting object 700. Mounting structure 12, cap 132, mounting adaptor 502, and other mounting elements of case structure 2000 shown in FIGS. 4A-4D may be the same as or substantially similar to those described in connection with FIGS. 2A-2D, and thus will not be described here.
  • One of ordinary skill in the art would appreciate that the mounting structure is not limited to those shown in FIGS. 4C and 4D, and may include any other similar structures that are desired. For example, a mounting structure may enable the mounting of a detachable handle, instead of mounting adaptor 502, to case structure 2000. In some exemplary embodiments, the mounting structure may include a hand-operable screw, instead of engaging elements 121 and 131 shown in FIG. 4A. For example, first bottom cover 1 a may include a mounting point, and by fastening a hand-operable screw using a screw cap, a mounting body of a detachable handle may be attached to first bottom cover 1 a through the mounting point. The attachment may enable manipulation of case structure 2000 through the detachable handle. The mounting point of first bottom cover 1 a, for example, may be a screw hole having a thread that is compatible with a standard camera tripod having a connection including, for example, ¼-20 UNC threads. Thus, a tripod or any other handling or supporting structures that have a tripod-compatible screw may be connected or coupled to case structure 2000.
  • In some exemplary embodiments, the mounting of a detachable handle may use a magnetic mounting mechanism. For example, first bottom cover 1 a may include at least one of a permanent magnet and a ferromagnetic material. The magnets may be composed of NdFeB, NIB, or Neo. An external mounting body may also include magnets or otherwise be configured to have magnetic properties so it can be magnetically coupled to first bottom cover 1 a in a substantially secure manner, such as without detachment by gravity, by vibration, or by the force of a user's operation of the portable electronic device enclosed in case structure 2000. The strength of the magnetic field of first bottom cover 1 a or the external mounting body, however, may be controlled so that it does not affect or substantially affect the operation of the portable electronic device. In addition, magnetic shielding materials may be included in first bottom cover 1 a to prevent the magnetic field from interfering with the electronic device. For example, a layer of sheet metal, metal screen, or metal foam may be included in first bottom cover 1 a. A layer of metallic ink or similar material may also be coated inside first bottom cover 1 a to provide the shielding. Further, one of ordinary skill in the art would appreciate that a mounting element, a detachable handle, or an external mounting body may be mounted to case structure 2000 by any type of mounting mechanism that is desired.
  • Referring to FIGS. 4B and 4C, in some embodiments, case structure 2000 may further include a carrying mechanism, such as an opening 55 at bottom side 50 of second bottom cover 1 b. Opening 55 may be configured to enable case structure 2000 to be attached to other objects or a carrying person via a hanging or carrying mechanism, such as a lanyard, rope, a band, a belt, a string, a hook, and/or any other similar carrying mechanisms. One of ordinary skill in the art would appreciate that case structure 2000 may include any number of openings located anywhere on case structure 2000.
  • FIG. 5A illustrates a perspective view of an exemplary case structure 3000. FIG. 5B illustrates an exploded view of case structure 3000 of FIG. 5A. Referring to FIGS. 5A and 5B, case structure 3000 is provided for housing or enclosing a portable electronic device (not shown), such as an Apple iPhone 5® device, and therefore enables preventing or reducing the likelihood of shock/drop/impact-, water-, dust-, and/or chemical-damage of the portable electronic device. Case structure 3000 may be substantially waterproof or water-resistant, such as substantially waterproof in compliance with class IP65 according to the U.S. National Electrical Manufacturers Association rating. The types of portable electronic devices that are capable of being enclosed in case structure 3000 may include, but are not limited to, a cell phone, a smart phone, an MP3 player, a portable computer, a tablet PC, a personal digital assistant, or any other similar devices.
  • Referring to FIGS. 5A and 5B, according to some embodiments, case structure 3000 may include bottom cover 1, first frame 2, film 3, second frame 4, and a layer 10. In some embodiments, first frame 2 may be detachably coupled to bottom cover 1. Layer 10 may be placed between bottom cover 1 and first frame 2. Layer 10 may also form an integral piece with bottom cover 1. Second frame 4 may be detachably coupled to or integrated with first frame 2 so as to form a single piece. Film 3 may be placed between second frame 4 and first frame 2. In some embodiments, the dimensions of bottom cover 1 and second frame 4 may be substantially the same or similar. In some embodiments, the dimensions of first frame 2 may be substantially similar or slightly smaller than bottom cover 1 and/or second frame 4 so that it may be coupled to or accommodated by bottom cover 1 and second frame 4. Referring to FIG. 5A, case structure 3000 is illustrated in an assembled condition, and thus, some elements of case structure 3000 may not be marked or labeled in FIG. 5A.
  • The material of the case structure 3000 may include polypropylene (PP), polycarbonate (PC), thermoplastic polyurethane (TPU), and/or any other material having similar characteristics. As an example, in some embodiments, the material of second frame 4 may include polycarbonate. And bottom cover 1 and first frame 2 may be formed by a double-injection molding process using thermoplastic polyurethane and polycarbonate. One of ordinary skill in the art would appreciate that the material of each element of the case structure 3000 may not be limited to those described above and may include any other material desired. For example, the material of some elements of case structure 3000 may include metal, alloy, stainless steels, nylons, hard plastics, iron, aluminum, lead, and/or other materials having similar characteristics.
  • FIG. 5C illustrates another exploded view of case structure 3000 of FIG. 5A. Referring to FIG. 5C, in some embodiments, first frame 2 may be formed or integrated with bottom cover 1 and therefore formed as an integral single piece (together shown as bottom cover 1 in FIG. 5C). As shown in FIG. 5C, second frame 4 may be detachably coupled to or assembled with bottom cover 1 (and the integrated first frame 2).
  • Referring to FIGS. 5B and 5C, in some embodiments, bottom cover 1 may include a plurality of, such as two, coupling structures 32, and second frame 4 may include a plurality of, such as two, corresponding engaging portions 34. Coupling structures 32 and engaging portions 34 may be configured to enable bottom cover 1 and second frame 4 to be hingedly, rotatably, movably, permanently, detachably, latchably, and/or snugly coupled or engaged to prevent or reduce the likelihood of undesirable separating of case structure 3000. For example, coupling structures 32, such as latches and engaging portions 34, such as corresponding latching slots, as shown in FIG. 5B (and any intervening structures or layers including first frame 2 and layer 10) may enable the user to close or assemble case structure 3000 and therefore enclose a portable electronic device. One of ordinary skill in the art would appreciate that positions of coupling structures 32 and engaging portions 34 shown in FIG. 5B are only exemplary and are not limiting. For example, coupling structures 32 and engaging portions 34 may be placed in other external edges of case structure 3000. One of ordinary skill in the art would appreciate that coupling structures 32 may also be attached to engaging portions 34 by any means.
  • Referring to FIGS. 5B and 5C, in some embodiments, coupling structures 32 may include an axis 321. When case structure 3000 is closed or assembled, for example, coupling structures 32 may, for example, pivotally rotate surrounding axis 321 and therefore couple to engaging portion 34. Axis 321 may enable coupling of coupling structures 32 in a manner that may allow coupling structures 32 to rotate, switch, move, slide, tilt, and/or perform other similar motions so as to engage with or couple to engaging portion 34. As an example, axis 321 may include a rotational axis and may be housed, coupled, or gripped in a concave portion, slot, groove, and/or other similar structures (not shown) in bottom cover 1.
  • Referring to FIGS. 5B and 5C, in some embodiments, second frame 4 may include groove 14 surrounding at least a portion of the periphery of second frame 4. Correspondingly, first frame 2 shown in FIG. 5B, or the integrated bottom cover 1 shown in FIG. 5C, may include convex portion 20. In some embodiments, groove 14 may be included in bottom cover 1 or first frame 2, and convex portion 20 may be included in second frame 4. In other words, groove 14 and convex portion 20 may be included in any of the second frame 4 and bottom cover1/first frame 2, as long as they are opposing each other.
  • Referring to FIGS. 5B and 5C, groove 14 may include a plurality of coupling portions 431, such as latches, hooks, protrusions, bars, and/or similar engaging or coupling portions. For example, as shown in FIG. 5C, the inner sidewall of groove 14 may include two or more coupling portions 431, such as engaging slots. Correspondingly, convex portion 20 may include a plurality of coupling elements 432, such as latches, hooks, protrusions, and/or similar engaging or coupling elements. In some embodiments, when case structure 3000 is closed, convex portion 20 may at least partially couple to or engage with groove 14. When convex portion 20 is at least partially and directly engaged with or coupled to groove 14, coupling elements 432 may hingedly, rotatably, movably, permanently, detachably, latchably, and/or snugly couple to or engage with the corresponding plurality of coupling portions 431, thereby forming a water-sealing or water-resistant structure for providing water-resistant or waterproof capability to case structure 3000. For example, as shown in FIGS. 5B and 5C, when case structure 2000 is closed, coupling elements 432, such as protrusions, may tightly engage with or snap into coupling portions 431, such as engaging slots. The coupling mechanisms, such as those described above, which include coupling elements 432 and coupling portions 431, may further provide or enhance the capability of case structure 3000 to enclose and protect the portable electronic device disposed therein, and thus prevent the undesired separation of case structure 3000.
  • In some embodiments, groove 14 may further include a seal strip (not shown) configured to provide additional or enhanced water-sealing or water-resistance capability of the water-sealing or water-resistant structure as discussed above. Additionally, the seal strip and the water-sealing structure, which may include groove 14, coupling portions 431, convex portion 20, and coupling elements 432, may also provide protection of the enclosed portable electronic device from being damaged by water, shock, dust, oil, mud, snow, vibration, spill, drop, impact, heat, frost, acid, chemical, corrosion, rain, sand, and/or other forms of intrusion. In some embodiments, when case structure 3000 is closed, the seal strip may be disposed within groove 14 and in contact with convex portion 20. The seal strip may also provide buffering or cushioning so that it reduces or prevents, for example, the likelihood of damage at the coupling area between bottom cover 1 and second frame 4. In some embodiments, the material of the seal strip may include silicone, rubber, thermoforming plastics, polyvinylchoride materials, polycarbonate, polyethylene terephthalate (PET), poly methyl methacrylate acrylic (PMMA), adhesive tape, and/or any material having similar characteristics. The seal strip may be formed by, for example, a molding process.
  • Referring to FIG. 5B, at least a portion of film 3 may be coupled to second frame 4, or be placed between bottom cover 1 and second frame 4, and may be configured to enable the user to view and operate the enclosed portable electronic device. For example, as shown in FIG. 5C, film 3 may be attached to the inner surface or a flat part of second frame 4. In some exemplary embodiments, film 3 may include materials such as thermoforming plastics, polyvinylchoride materials, polycarbonate, polyethylene terephthalate (PET), poly methyl methacrylate acrylic (PMMA), adhesive tape, and/or any other materials having similar characteristics. Film 3 may be flexible but also may have an enhanced strength so that it may withstand a water pressure under a higher water resistance standard. As an example, film 3 may be capable of withstanding a condition that is specified in the IPX7 standard, i.e., a water immersion for at least 30 minutes at a depth of at least one meter. Film 3 may also be capable of withstanding a condition of a higher IPX8 standard, i.e., a continual submersion in water under conditions which are identified by the manufacturer. As another example, film 3 may also be capable of withstanding the IP65 standard.
  • Film 3 may also be a clear/transparent or substantially clear/transparent water-resistant film so that a user can view the screen or a substantial portion of the screen of the portable electronic device. In addition, film 3 may also enable a user's operation of the portable electronic device when it is enclosed in case structure 3000. For example, some portable electronic devices may have capacitive-type touch sensors that are incorporated in the touch-point screens. A user may operate these portable electronic devices by touching and/or moving a fingertip on the surface of the touch-point screen. Film 3 may thus be a touch-sensitive or transmissive film that enables the user to operate a touch-point screen of the portable electronic device through film 3. As a result, operations may be carried out without opening case structure 3000. In other words, film 3 may enable the portable electronic device to be operated when it is in a humid, water-exposing condition, or under other conditions that require the portable electronic device to be enclosed. One of ordinary skill in the art would appreciate that film 3 may also be other types of films that can enable operation of the portable electronic device, such as resistance-sensitive films.
  • In some embodiments, film 3 may also be an anti-reflection film, an anti-glare film, an anti-fingerprint film, a monitor filtering film, and/or other similar films. For example, film 3 may filter out the light reflected from the smooth glass surface of the touchscreen device as well as the radiation emitted from the portable electronic device. This may be used to protect the user's privacy by decreasing the viewing angle of the touchscreen of the portable electronic device. In addition, film 3 may also be able to dissipate static electrical charge buildup. Film 3 may also be polarized, colorized, or tinted, depending on the application.
  • A portable electronic device may have buttons or switches, such as the “home” button on an Apple iPhone® 5 device. Therefore, in some exemplary embodiments, film 3 may include a corresponding convex or concave shape to enable convenient operation of the portable electronic device. As an example, for an Apple iPhone 5® device, film 3 may include a concave circle near the bottom edge (not shown) for operating of the “home” button. One of ordinary skill in the art would appreciate that the concave circle may be positioned anywhere on film 3. In addition, film 3 may include any number of shapes, buttons, membranes, etc., which may enable ease of operation of the portable electronic device.
  • Referring to FIGS. 5B and 5C, in some embodiments, film 3 may be detachably or integrally coupled to a sealing area 40 of second frame 4 through an attaching mechanism, such as a seal 8 shown in FIG. 5B. Seal 8 may be directly disposed on sealing area 40, such as a flat part, of second frame 4. Seal 8 may be a VHB material. Seal 8 may also be formed by coating any colloidal substances on sealing area 40 of second frame 4 to provide the adhesion effect. Moreover, seal 8 may include an adhesive material that is waterproof, such as waterproof up to one meter below the water surface, or water-resistant, such as water-resistant to a water-jet. In some embodiments, when the adhesive materials are used, film 3 may not be replaceable. That is, replacing film 3 may cause damage to film 3 and render it unusable. Thus, in these embodiments, film 3 may be made of or combined with strength-enhancing, anti-scratch, or anti-breaking material, so that damage to film 3 may be reduced or eliminated. Film 3 may thus have a longer life span. In some other embodiments, seal 8 may allow film 3 to be replaced if it is scratched or damaged. Film 3 in these embodiments may have a shorter life span but may be relatively inexpensive. In addition, seal 8 may also be configured to be impact-absorbing so that it may prevent or reduce the likelihood of damage caused by impact, impinge, shock, and/or drop that are imposed at the second frame and/or film 3 of case structure 3000.
  • FIG. 5D illustrates a partial, exploded view of case structure 3000 of FIG. 5A. Referring to FIGS. 5B-5D, layer 10 may be placed between bottom cover 1 and second frame 4. Layer 10 may be detachably coupled to bottom 1, or integrated with bottom cover 1 so to form an integral piece. Layer 10 may substantially cover the backside of the enclosed portable electronic device. In some embodiments, layer 10 may have a flat back surface (not shown).
  • FIG. 5D illustrates an exploded view showing layer 10 separated from bottom cover 1 and first frame 2. Referring to FIG. 5D, in some embodiments, layer 10 may include additional cushioning, which may have a convex-concave pattern with an enhanced thickness at the convex area. The additional cushion of layer 10 may be configured to provide additional impact absorption or shock resistance. The additional cushioning may include a material that is similar or different to that of layer 10. For example, the material of the additional cushioning can be soft rubber, plastic, TPE, thermoplastic polyurethane (TPU), and/or any other material having similar characteristics. Furthermore, the additional cushioning may be substantially transparent, opaque, or reflective. For example, the additional cushioning may be reflective so that sunlight can be reflected in order to prevent protective case structure 3000 and the enclosed portable electronic device from being exposed to excessive heat or an increased temperature.
  • Referring to FIG. 5D, the additional cushioning of layer 10 may include one or more pyramid-shaped cushioning elements 151. Pyramid-shaped cushioning elements 151 have a greater thickness at their centers than at their edges. As a result, when an external force or stress is applied to case structure 3000, the increased thickness enables pyramid-shaped cushioning elements 151 to absorb extra external force or stress and therefore enhances the cushioning capability of case structure 3000. As a result, the portable electronic device that is enclosed in case structure 3000 may receive additional protection against physical impact, stress, shock, collision, etc.
  • Moreover, the material that is included inside pyramid-shaped cushioning elements 151 may or may not be the same as the material in other areas of pyramid-shaped cushioning elements 151. For example, pyramid-shaped cushioning elements 151 may be filled with air or any other gas, so that case structure 3000 may have a reduced weight, while still providing additional cushioning to the enclosed portable electronic device. One of ordinary skill in the art would appreciate that the cushioning elements may alternatively have any other shapes or form any other patterns that are desired. The cushioning elements may also use any material that may provide additional absorption of physical impact, stress, and/or shock-resistance.
  • Referring to FIG. 5B, in some embodiments, first frame 2 may further include a plurality of casing buttons, such as casing buttons 42, 43 a, 43 b, and 44. Casing buttons 42, 43 a, 43 b, and 44 may be depressible and may be configured to operate their respective underlying functioning mechanisms, such as a push button, a key, a switch, a sliding control, a knob, or any other control mechanism, of the portable electronic device. As an example, the material of casing button 42 may include soft plastic, such as polypropylene, soft rubber, and/or any other materials having similar characteristics.
  • Referring to FIG. 5B, in some embodiments, casing button 42 may include an axis 421. When case structure 3000 is closed or assembled, for example, casing button 42 may be detachably, movably, or permanently coupled to or disposed in an opening 27 through axis 421. Axis 421 may enable coupling of casing button 42 in a manner that may allow casing button 42 to switch, move, slide, tilt, and/or perform other similar motions. As an example, axis 421 may include a rotational axis and may be housed, coupled, or gripped in a concave portion, slot, groove, and/or other similar structures (not shown) in first frame 2. In some embodiments, such structure may enable casing button 42 to engage in a motion as described above to, for example, turn on and off a functional button of the enclosed portable electronic device. In some embodiments, such structure may itself move, slide, tilt, and/or perform other similar motions to, for example, turn on and off a functional button of the enclosed portable electronic device.
  • Referring to FIG. 5B, in some embodiments, casing buttons 43 a, 43 b, and 44 may also be detachably, movably, or permanently coupled to or disposed in openings 28 a, 28 b, and 29 of bottom cover 1, respectively. In some embodiments, when case structure 3000 encloses the portable electronic device, openings 27, 28 a, 28 b, and 29 may correspond to the ring/mute switch button, the volume-up button, the volume-down button, and the power button of the portable electronic device, respectively. Therefore, a user may operate the buttons of the portable electronic device (not shown) by, for example, pressing on casing buttons 42, 43 a, 43 b, and 44 of case structure 3000. One of ordinary skill in the art would appreciate that case structure 3000 may also include any number of openings and casing buttons corresponding to the underlying functioning mechanisms. The openings and casing buttons may be located, disposed, or arranged at any locations desired.
  • Referring to FIG. 5B, in some embodiments, first frame 2 may further include openings 22 and 23. Openings 22 and 23 may be placed, for example, corresponding to the positions of an earphone jack and a charging and communication connector of the portable electronic device, respectively. Therefore, when the portable electronic device is accommodated, housed, or enclosed in case structure 3000, openings 22 and 23 may enable a user to operate the earphone function and charging function of the portable electronic device without the need to remove the portable electronic device from case structure 3000.
  • Referring to FIG. 5B, in some embodiments, bottom cover 1 may include an opening 221 corresponding to opening 22 of first frame 2. Case structure 3000 may also include cap 9. In some embodiments, cap 9 may have a shape corresponding to that of opening 22 and a dimension that is similar or slightly smaller than that of opening 22. As a result, when bottom cover 1 and first frame 2 are coupled together, cap 9 of case structure 3000 may pass through opening 221 of bottom cover 1, and snugly plug or insert into opening 22 of first frame 2. Cap 9 may thus be configured to seal opening 22 and provide, for example, substantial waterproof or water-resistant capability. As another example, opening 22 and cap 9 may each include screw threads and therefore, cap 9 may be coupled to, inserted into, or screwed into opening 22 through the engaging of the screw threads. One of ordinary skill in the art would appreciate that cap 9, opening 221, and opening 22 may include any structure desired. For example, in some embodiments, cap 9 may not be separated from and may instead be integrated with first frame 2 or bottom cover 1, such as by a connector (not shown), so that unintentional misplacement of cap 9 may be avoided. Furthermore, one of ordinary skill in the art would appreciate that the coupling mechanism of cap 9, opening 221, and opening 22 is not limited to those described above and may include any other similar mechanisms.
  • Referring to FIG. 5B, in some embodiments, bottom cover 1 and second frame 4 may each include a carrying mechanism, such as an opening 55 a and an opening 55 b, respectively. When each bottom cover 1 and second frame 4 include a carry mechanism, the carry mechanisms may correspond to each other. For example, as shown in FIG. 5B, opening 55 a and opening 55 b may correspond to each other near the same corner of case structure 3000. Therefore, when the bottom cover 1 and second frame 4 are coupled to each other (e.g., when case structure 3000 is closed), opening 55 a and opening 55 b may form a single hole configured to receive a lanyard, and thus enable case structure 3000 to be attached to other objects carried by a person via a hanging or carrying mechanism, such as a rope, a band, a belt, a string, a hook, and/or any other similar carrying mechanisms. One of ordinary skill in the art would appreciate that case structure 3000 may include any number of openings, such as openings 55 a and 55 b, located anywhere on case structure 3000. For example, in some embodiments, case structure 3000 may only include one of openings 55 a and 55 b.
  • Referring to FIG. 5B, bottom cover 1 may further include lens protecting structure 16, which may include first structural element 161 and second structural element 162. First frame 2 may also include opening 19 corresponding to lens protecting structure 16 of bottom cover 1. In addition, case structure 3000 may further include a lens 165. Lens 165 may be disposed in opening 19. For example, lens 165 may have a size that is similar to or slightly smaller than opening 19, and thus, may be snugly disposed, placed, or inserted in opening 19. In some embodiments, when lens protecting structure 16, opening 19, and lens 165 are coupled together, case structure 3000 may provide protection of the camera lens of the enclosed portable electronic device. In some embodiments, first structural element 161 and second structural element 162 of lens protecting structure 16 may correspond to the camera lens and the flash functions of the portable electronic device, respectively. In some embodiments, lens 165 may include a double anti-reflective coating for providing a high-transparency feature, thereby enabling lens 165 to be anti-reflective. An anti-reflective coating may enable, for example, the portable electronic device to obtain improved picturing effect and result. One of ordinary skill in the art would appreciate that lens 165 may also have any other coating desired, such as anti-glare and anti-scratch coatings.
  • FIG. 6A illustrates a perspective view of another exemplary case structure 4000. FIG. 6B illustrates an exploded view of case structure 4000 of FIG. 6A.
