Description

TECHNICAL FIELD

The presently disclosed subject matter relates generally to electronic device cases. Particularly, the presently disclosed subject matter relates to electronic device cases with tracks for holding accessories and related methods.

BACKGROUND

Portable electronic devices (such as cell phones) have become a primary communication device for a large portion of the public. Cell phone cases are used by most consumers that have cell phones to provide a degree of protection in the event of an impact, such as dropping the phone. Moreover, the case can protect the screen or camera lens by providing a ledge that can keep the surface raised. In addition to their phones, it is common for people to carry additional items and/or accessories when they leave their home, such as wallets, keys, writing utensils, and the like. As the number of accessories that a person carries increases, the more difficult it becomes to safely and securely carry each item. Currently, most users carry their cell phone and accessories in separate pockets or within separate compartments of a bag, purse, or briefcase. When a user desires to access a phone and/or accessory, he or she must rummage around to find the desired item. This can be time consuming and inconvenient. Furthermore, when a user carries multiple accessories, there is an increased likelihood that one or more items can be misplaced or dropped. It would therefore be beneficial to provide an electronic device case that allows for the convenient and customizable attachment and detachment of one or more accessories.

It will be understood that these terms and those discussed above are intended to encompass different orientations of the device in addition to the orientation depicted in the drawing figures.

The embodiments set forth below represent the necessary information to enable those skilled in the art to practice the embodiments and illustrate the best mode of practicing the embodiments. Upon reading the following description in light of the accompanying drawing figures, those skilled in the art will understand the concepts of the disclosure and will recognize applications of these concepts not particularly addressed herein. It should be understood that these concepts and applications fall within the scope of the disclosure and the accompanying claims.

The presently disclosed subject matter is generally directed to a device case that provides for removable attachment of one or more accessories. FIGS. 1a and 1b illustrate one embodiment of a protective case used with device 10. Specifically, case 15 comprises one or more tracks 20 that allow a variety of accessories 25 to be attached and/or removed as desired by the user. In this way, one or more accessories can be added, removed, oriented, and/or arranged depending on a particular use of the device. Advantageously, each accessory locks into place on track 20 such that it is fully supported, as described in more detail herein below.

As set forth above, the disclosed attachment system includes case 15 used with device 10. The term “device” broadly refers to any of a wide variety of devices, including (but not limited to) cellular phones, smart phones, tablets, laptop computers, handheld gaming devices, GPS units, portable music players, gaming consoles, e-readers, cameras, digital cameras, smart watches, personal digital assistants, and the like. In some embodiments, device 10 is portable and can be carried in a user's hand or with a user's belongings (purse, briefcase, vehicle, etc.).

FIGS. 2a-2c illustrate one embodiment of case 15 that provides an overall enclosure and protection of device 10. Particularly, the case comprises panel 30 and sidewall 35 that join together to form cavity 36. Cavity 36 is sized and dimensioned to receive device 10. Panel 30 comprises inner face 31, opposing outer face 32, and two pairs of parallel side edges. Inner face 31 directly contacts one surface (e.g., the rear face) of a corresponding device. The panel outer face forms an exterior surface of the case. In some embodiments, the “rear face of a device” can refer to the face that the user does not interact with. For example, the rear face of a smart phone is the face opposite the viewing screen. The panel is sized and shaped to conform to the back face of device 10. Thus, panel 30 can be substantially flush against the back face of a device.

In some embodiments, panel 30 can include at least one aperture 40 sized and shaped to accommodate a corresponding feature in device 10. For instance, the aperture can be configured to align with a camera lens located on the rear face of the device when the device is seated within the case. It should be appreciated that aperture 40 can be positioned at any suitable location and can be configured in any desired shape and size.

Further, any number of apertures can be included on case 15. However, it should be appreciated that aperture 40 is optional and the disclosed case can be configured without an aperture.

Sidewall 35 is formed about the perimeter of panel 30 to retain the device within the case. In some embodiments, sidewall 35 can include groove 45 configured to receive and retain a lateral edge of device 10. In this way, the sidewall prevents device 10 from inadvertently being removed from the case. The sidewall can include at least one access 46 that allows a user to interact with a control button (e.g., volume, charging port) on the lateral edge of the device when the device is seated within case 15. Access 46 can be formed as an aperture, a raised portion, and/or a recessed portion. In this way, a user can interact with buttons and other functional elements of the device through case 15 as needed. For example, the access can be respectively associated with a power button and one or more volume buttons provided on a device (e.g., a tablet computer).

Case 15 can be constructed from any desired material. For example, the case can be constructed from silicone, polymeric material, rubber, metal, fiberglass, wood, fabric, or combinations thereof.

The case can be constructed using any suitable method known in the art, including (but not limited to) injection molding, blow molding, extrusion, coextrusion, compression molding, welding, and the like.

In some embodiments, the case can be constructed as a single piece that fits around device 10. In other embodiments, the case can be constructed from two or more pieces that releasably or permanently join together around the device.

As set forth above, at least one face of case 15 includes one or more tracks 20. The term “tracks” broadly refers to any attachment element that allows for the releasable coupling and/or locking of one or more accessories. In some embodiments, each track 20 is permanently attached to one face of case 15, such as outer face 32. The track can be permanently attached using any known method, such as (but not limited to) the use of adhesive, welding, thermoforming, mechanical elements (e.g., screws, bolts, clips), or combinations thereof. Thus, in some embodiments, the tracks are integrated into the case.

Alternatively, track 20 can be releasably attached to the case, such as in embodiments wherein only one track or a portion of one track is needed. The track can be releasably attached to the case using any known method, such as (but not limited to) the use of magnets, hook-and-loop closures, snaps, and the like. In this way, the location of track 20 can be customized by the user as desired or needed for a particular application. Thus, if a user intends to only carry a single small accessory, he can attach a correspondingly-sized track to rear face 32. Therefore, a user can customize tracks 20 as desired (e.g., both horizontal and vertical tracks added as needed for a selected number of accessories), as shown in FIGS. 3a and 3b. In this way, existing cases can be easily retrofit to include tracks for the releasable attachment of accessories.

Tracks 20 can be constructed from any desired rigid or semi-rigid material, such as (but not limited to) metal (e.g., stainless steel, aluminum, copper), polymeric material, wood, composite material, or combinations thereof.

Case 15 can include any desired number of tracks 20. For example, in some embodiments, the case can include 1-10 tracks (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10). However, the presently disclosed subject matter is not limited and the case can have more than 10 tracks. When case 15 includes more than one track, the tracks can be arranged in parallel, as shown in FIG. 2c. However, the presently disclosed subject matter is not limited and the tracks can be arranged in any configuration relative to another track. For example, FIGS. 4a and 4b illustrate tracks 20a and 20b configured perpendicularly and T-shaped relative to each other. However, tracks 20 are not limited to parallel and perpendicular configurations, and can be angled relative to each other, as shown in FIG. 4c. The term “angled” can refer to any angle, such as an acute or obtuse angle. Thus, the tracks can be angled relative to each other or to the horizontal or vertical at least about (or no more than about) 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 110, 115, 120, 125, 130, 135, 140, 145, 150, 155, 160, 165, 170, 175, or 180 degrees. Thus, the tracks can be configured in any way that allows for linear movement in at least one direction.

Although depicted on rear face 31 of the case, one or more tracks can be configured on any face of the case. For example, FIG. 5a illustrates one embodiment of case 15 comprising track 20 configured on an outer face of sidewall 35.

In some embodiments, one or more accessories can include track(s) to accessorize the accessories. Particularly, FIG. 5b illustrates one embodiment of accessory 25 comprising accessory track 21. The accessory track allows for the releasable connection of one or more additional accessories.

As set forth above, track 20 can include any configuration that provides for the attachment, locking, and release of a desired accessory. As illustrated in FIGS. 6a and 6b, track 20 includes a pair of parallel raised ridges 45 on either side of central groove 50. Each groove provides an opening in track 20 through which a corresponding portion of an accessory is received. In some embodiments, the accessory can move as desired by the user along track 20 to a desired location.

Ridge 45 can have any desired height 41 or width 42, such as about 0.05-1 inches. Thus, each ridge can have a height and/or width of at least about (or no more than about) 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, or 1 inch. However, the presently disclosed subject matter is not limited and the ridge can have a height and/or width greater or smaller than the ranges given herein.

Groove 50 can have any desired cross-sectional shape, such as (but not limited to) a T-shape as shown in FIG. 7a, triangular shape as shown in FIG. 7b, trapezoidal shape as shown in FIG. 7c, rounded shape as shown in FIGS. 7d and 7e, diamond shape as shown in FIG. 7f, pentagonal shape as shown in FIG. 7g, hexagonal shape as shown in FIG. 7h, cross shape as shown in FIG. 7i, or abstract shape as shown in FIG. 7j. It should be appreciated that the cross-sectional shape of groove 50 (and corresponding ridges 45) are not limited and can be configured in any desired shape. In some embodiments, the groove can include at least one tapered side wall. It should further be appreciated that groove 50 can be configured in any length, any width, any depth, and any shape.

Track 20 can be configured in any desired length and width, depending on the length and/or width of the corresponding device. In some embodiments, track 20 can span approximately the full length 55 and/or width 60 of case 15, as shown in FIG. 8. The term “length” refers to the longest distance in the longitudinal direction. The term “width” refers to the longest distance perpendicular to the length. Alternatively, one or more tracks can span about 10-95 percent the length and/or width of a case. Thus, the track can span at least about (or no more than about) 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, or 95 percent of the length and/or width of case 15.

In some embodiments, the track can include electrical contact area 16 along the at least a portion of the length of the track. The electrical connection can be used to direct power from an electronic accessory to the electronic device, such as an extra battery to charge the electronic device. Alternatively, the electrical contact area can direct power from the electronic device to the accessory to power the accessory. Moreover, the case (using the track system) can direct power from a power source on or within the case to an accessory along the track, bypassing the electronic device all together. In some of the methods described, the electronic accessory can be charged at the same time as the electronic device.

The electrical contact area on the case can be a solid surface along the edge of track 20, where there is a positive and negative contact area for power. The contacts can be in a single track as shown in FIG. 9a or on separate tracks. In some embodiments, the mating shape can include spring-loaded contact 56 where a connection can be made along the track, as shown in FIG. 9b. However, it should be appreciated that the contact is not limited to spring-loaded embodiments, and that any configuration that allows connection to be made along the track can be used. Alternatively, connections can be made at multiple points along track 20 corresponding to locking positions, as shown in FIG. 9c. Optionally, these points can be recessed to protect the contact area and to prevent shorting. The mating shape can have a spring loaded contact 57, similar to an electric pogo pin, that makes contact with the contact area on a track at a specific point, as shown in FIG. 9d. However, it should be appreciated that the male shape can have multiple contacts in any desired configuration.

The contact tracks in both embodiments can be manufactured on a printed circuit board (PCB) and inserted or molded into the case. Optionally, the PCB can also include a microprocessor, BLUETOOTH® transmitter/receiver, and/or other electrical components to enhance the functionality of the case and the accessories.

The singular contact shown in FIGS. 9a and 9b can provide power, while the individual contacts shown in FIGS. 9c and 9d can provide more functionality (e.g., known positioning of the accessory that is inserted by identifying individual connections rather than a singular one). The connections can provide more than just power; multiple pins can send and receive data or other information through direct connection to the electronic device, similar to a USB that has positive power, negative power, positive data, and negative data. The pins are not limited to the example above and can include any pin out connections (such as a USBC connection, etc.). These connections can allow the electronic device to connect to the case and accessories. It should be noted that the individual pin locations, in the example of the data transmission above, are not limited to a singular point but can be multiple points along the track. This is analogous to a USB strip or similar where multiple accessories can be added to communicate with electronic device.

In some embodiments, when an accessory is inserted into track 20, the rail system along with electronics embedded in the case have the capability of interacting with accessories through sensing, actuation, and/or control to describe and analyze a situation, and make decisions based on the available data in a predictive or adaptive manner, thereby performing smart actions. In one example, the position can be known and displayed on an app within the electronic device. The app can recognize which accessory has been attached and provide logic or data transmission to and from. For example, if an extra battery was inserted in the track along with chargeable earphones, the user could instruct the app to automatically engage the battery to charge the phone when the phone gets below 20%, use the phone power to charge the headphones when above 80% or simply turn it on and off when needed. This data transfer has many useful features such as expanding memory, transferring data from the electronic device to an SD card or USB through an accessory, accessing multiple video game cartridges, adding BLUETOOTH® transmitters to control multiple devices rather than a singular one etc. This could also be used for a docking device connection or connecting a phone to a gaming controller, virtual reality device where the tablet or phone could be used as a screen and external controls, buttons, features could be added.

Each ridge can include one or more recesses 55 that allow an accessory to be locked into place on the track. Specifically, the recesses provide a locking feature at specific set points for attachment of one or more accessories. FIGS. 10a and 10b illustrate one embodiment of ridge 45 comprising a series of recesses 55. The recesses can be uniformly or non-uniformly placed along the length (or a portion of a length) of the ridge. Any number of recesses can be included on a particular ridge. Further, the recesses can be configured in any desired size or shape as desired by the user. As described in detail below, each recess allows a corresponding accessory to be locked into place at a certain location on track 20, allowing for maximum configurability.

In some embodiments, the recesses function similar to a ratchet and pawl mechanism. The term “ratchet” refers to a mechanical device that allows continuous linear or rotary motion in at least one direction, while preventing motion in the opposite direction. The term “pawl” refers to any of a wide variety of curved or shaped bars or levers that include a free end that engages with a ratchet such that the ratchet can move in one direction. As illustrates in the Figures, the ratchet is flat and configured on case 15 and the pawl mechanism is positioned on the accessory. When inserted into track 20, the accessory can freely move in one direction where the locking mechanism inclines on a ramp. At the top of the ramp, the locking mechanism falls to a flat side of the ramp, thereby locking it into place until the locking mechanism is lifted, as illustrated in FIG. 10b. It should be appreciated that the shape of locking mechanism is not limited.

One or more accessories cooperate with tracks 20 to allow customization of case 15. The term “accessory” refers to any desired element that can releasably attach to track 20. Suitable accessories can therefore include (but are not limited to) a wallet, key, key card, keychain, pocket knife, earbuds, writing utensil, medication bottle, coin purse, flashlight, tape measure, photograph frame, notepad, watch, money clip, card holder, laser pointer, tool (screwdriver, bottle opener, tweezers, etc.), and the like. In some embodiments, the accessories can include non-function item(s), such as buttons, pins, patches, and other adornments that allow a user to express his personality or interests. Accessory 25 can therefore include any item capable of attaching to case 15.

Accessory 25 includes one or more protrusions 60 that cooperates with track 20. Specifically, the protrusion is sized and shaped to fit into track groove 50. For example, FIGS. 11a and 11b illustrate one embodiment of accessory 25 comprising protrusion 60 configured in a “T” shape. Protrusion 60 can be permanently or releasably attached to one surface of the accessory, such as through the use of adhesive, welding, snap-fit attachment, pressure-fit attachment, magnets, hook-and-loop closures, mechanical elements (screws, clips, etc.), and the like.

Protrusion 60 can be configured in any desired size and/or shape, so long as it can 10 be retained within track groove 50. For example, the protrusion can connect to groove 50 via a dovetail connection. However, it should be appreciated that a tapered dovetail connection is only one of many possible connections. In some embodiments, the protrusion can have about the same or slightly smaller size and/or shape as groove 50 to allow for a snug fit when the protrusion is received within the groove. In some embodiments, the protrusion can have a squared shape to prevent rotation of the accessory. Alternatively, the protrusion can have a rounded shape when the user desires to rotate the accessory.

Accessory 25 can be constructed from any desired material, such as (but not limited to) wood, metal, polymeric material, rubber, fabric, or combinations thereof.

Accessories 25 can be arranged on track 20 horizontally and/or vertically. The term “horizontally” refers to any direction parallel to the level floor. The term “vertically” refers to the direction perpendicular to the level floor. The accessories can be configured, added, and/or removed based on the preference of the user in either a horizontal or vertical manner. Specifically, accessories 25 can be positioned at any desired location on track 20 by inserting protrusion 60 into groove 50. As a result, case 15 can be customized with one or more accessories as needed.

In use, case 15 is configured around a corresponding device 10 using methods well known in the art, as shown in FIGS. 12a and 12b. In some embodiments, the case is constructed from an elastomeric material that allows the case to stretch and adjust about the exterior of the device. In other embodiments, the case is assembled using two or more elements that join together around a corresponding device. As shown, one or more tracks are attached to one surface of cover 15, such as (but not limited to) the back face of the cover.

One or more protrusions 60 are attached to a desired accessory as desired by the user. The protrusion can be permanently attached to the accessory, such as through the use of adhesive, welding, mechanical attachments (e.g., screws, bolts) or molded, machined, and the like so that the protrusions and the accessories are a single piece. Alternatively, the protrusion can be releasably attached to accessory 25, such as through the use of hook-and-loop closures, magnets, clips, and the like. FIG. 12c illustrates one embodiment of an accessory (money clip 26) with attached protrusion 60. The protrusion can be attached to any surface of the accessory.

The protrusion can then be inserted into the groove of a corresponding track, as shown in FIGS. 12d and 12e. The size and shape of the protrusion are accommodated within groove 50. In some embodiments, protrusion 60 and groove 50 have about the same size and shape to provide a snug fit and reliably retain the protrusion within the track system. In some embodiments, the size of the protrusion is slightly smaller than the size of groove 50. As described above, one or more recesses 55 along track 45 are spaced to allow the user to lock accessory 25 into the track. In some embodiments, protrusion 60 is inserted into track 45 at the desired location of recess 55. Optionally, when the protrusion placed in a locked position with respect to the track, there may be an audible sound (e.g., a clicking or snapping sound) to indicate to the user that the accessory is properly locked in place. In some embodiments, one or more accessories can be deposited on a single track, as shown in FIG. 13a. Alternatively, one or more accessories can be configured on adjacent tracks, as shown in FIG. 13b. In some cases, the track will be large enough to hold multiple accessories. In such cases, when the track has extra capacity, the track can provide additional storage for more than one accessory.

When a user desires to remove the accessory from case 15, he simply unlocks the accessory to remove protrusion 60 from track 50, as shown in FIGS. 14a and 14b. In some embodiments, this can be accomplished by applying light pressure to lock 61 on the accessory where pawl 62 becomes disengaged and allows the accessory to slide to a new position and/or be removed altogether. The term “pawl” can refer to any element that allows an accessory to be removably attached to a track. Further, pawl 62 is not limited to the embodiment shown and can be disengaged by squeezing, pushing, light touch, etc. When pressure is released, the pawl reengages and locks. The lock mechanism is not limited and can include any lock/release design. For example, in some embodiments, the lock can include a spring detent feature that can allow the accessory to slide when pressure is applied to the accessories for easier removal when desired. When pressure is applied, the protrusion is released from recess 55 and track 50. The accessory can then be removed and replaced with a different accessory as needed.

The disclosed case provides many benefits and advantages. For example, the case can be customized with a variety of different accessories, depending on the desires of the user and/or a particular situation.

Case 15 protects device 10 from damage due to accidental dropping or exposure 15 to dirt, liquids, and the like.

The disclosed case increases convenience for the user by providing accessories 25 within easy reach. The user does not have to search a second location to retrieve the accessory.

Because a desired accessory is close at hand on case 15, there is a decreased 20 likelihood that the accessory will become misplaced or lost.

Further, the disclosed case is relatively inexpensive to manufacture, and is safe and easy to use.

In addition, the disclosed case is not limited to a single use. Rather, a wide variety of different uses (and different accessories) can be used with the disclosed case.

Compared to other cases that may include/incorporate one accessory, such as a wallet, this does not limit the case to a singular use and the uses can be interchanged.

In some embodiments, the case can be attached to a mounting device and/or accessory that secures the phone with a mechanical lock, adhesives, elastic, and the like. Particularly, prior art devices typically require the attachment of accessories through the use of adhesives, friction or clamps, and/or elastic elements (e.g., rubber band) around the corners. The disclosed rail system is more secure because it does not rely on adhesives that can degrade friction and do not hold well and/or the use of elastic that is unreliable.

The case could be attached to a mounting device/accessory that better secures the phone with a mechanical lock versus friction, adhesives or elastic means.

The accessories, also containing the rail attachment method, could allow bundling of the accessories together, as to allow separation from the case, while maintain security of the bundle.

In some embodiments, one or more accessories can include a track as described 10 above. Such embodiments allow the bundling of accessories together to allow the accessories to separate from the case, but also maintain security of the bundle.

Accessories could be grouped tougher depending on the user's goals. For example, a daily “accessory pack” could include a wallet, car keys, and a mount. A boating “accessory pack” could include a floatation device, bottle opener and small scissors for cutting fishing line etc.

The disclosed system can provide for the grouping of accessories together as desired by a user. For example, a daily “accessory pack” can be customized to include accessories used on a daily basis (e.g., wallet, car keys, mount). Further, a boating “accessory pack” can include a floating device, bottle opener, scissors, and the like.

The male/lock portion of the attachment method could be attached by any means necessary to any device such as sewn into clothing for runners or glued onto a bike helmet to function similar to a GOPRO® camera.

In some embodiments, one end of a chain or rope can be attached to the case (while the other end is attached to the user or another item) to provide an added layer of security, preventing or reducing the likelihood of theft and/or misplacement.

The disclosed case further allows a user to express his personality. Specifically, the user can customize the case with accessories that reflect the user's interests and/or identity. It is noted that an accessory can be any electronic device that can operate together with another electronic device or beneficial to attach to another electronic device via its case. Example accessories include, but are not limited to, speakers, camera, battery, lighting, temperature sensing device, humidity sensing device, barometric pressure sensing device, microphone amplifier, motion sensor, extra storage, credit card reader, plug adaptor (e.g, USBC, USB, Lightning, etc.), breathalyzer, distance sensor (e.g., laser, time of flight, ultrasonic, lidar, light sensor (e.g., UV, Infrared, visible light)), thermal camera, keypad, keyboard, joystick, other controllers, air quality sensor, gas sensor, GPS antenna, altimeter, machine learning camera, fingerprint sensor, radiation sensor, potentiometer, encoder, barcode scanner, muscle sensor, beam break sensor, projector, plug adaptors, blood sugar monitor, pulse oxygen reader, earbud holders, and the like.

FIG. 15a illustrates a rear view of an electronic device case 1500 having a track for holding accessories in accordance with embodiments of the present disclosure. Referring to FIG. 15a, the electronic case 1500 includes a body 1502 that defines an interior space (not shown in this figure) for holding an electronic device (not shown in this figure). The body 1502 can define sides 1504, 1506, 1508, and 1510 that can hold, support, and protect the electronic device. Further, the sides 1504, 1506, 1508, and 1510 can define an opening (not shown in this figure) that opens to the front side of the electronic case 1500 for receiving the electronic device. A back side of the opening can be defined by a rear side 1511, which may be substantially flat in shape. The rear side 1510 can have edges that meet and be attached to the sides 1504, 1506, 1508, and 1510.

In this example, the electronic case 1500 shown in FIG. 15a is sized and shaped for holding a smartphone and described as such. However, it should be understood that the electronic case 1500 may alternatively be suitably sized and shaped to hold any other suitable electronic device such as a tablet computer.

With continuing reference to FIG. 15a, the electronic case 1500 includes a track attached to the rear side 1511. In this example, the track includes two rails 1512 and 1514, but may alternatively include any suitable number of rails. Rails 1512 and 1514 extend substantially along a length of the body 1502 between the upper end (wherein side 1504 is attached) and the lower end (where side 1510 is attached). In this example, rail 1514 extends nearly the entire length between the upper end and the lower end. Rail 1512, in this example, extends less distance than the length of rail 1514.

Rails 1512 and 1514 can cooperate to hold one or more accessories. In FIG. 15a, the rails 1512 and 1514 are holding accessories 1516 and 1518. Accessory 1516 is a speaker, and accessory 1518 is a battery. Any other suitable type of accessories can be held by the rails 1512 and 1514.

In this example, the speaker 1516 can be operatively connected to the electronic device for playing audio (e.g., music) from the electronic device. The speaker 1516 can be connected to the electronic device via a short range, wireless technology, such as BLUETOOTH® wireless technology. Alternatively, the battery 1518 can have electrical contacts integrated therein for a hardwired connection to the electronic device through which electrical signals can be transmitted for playing music via the speaker 1516.

Further in this example, the battery 1518 can be operatively connected to the electronic device for providing electrical power the electronic device.

In accordance with embodiments, the battery 1518 can be used as a backup to an electronic device (e.g., smartphone). Further, the battery 1518 can include all electronics for other accessories to allow for a small footprint of the other accessories. In an example, the battery 1518 may include wireless communication technology (e.g., BLUETOOTH® wireless technology) for communicating data with the electronic device, such as for interacting with an application (or “app”) residing on the electronic device.

Another rail 1520 is attached to the side 1510 and can cooperate with the rail 1514 to form another track near the upper end of the body. This other track (formed by the upper portion of rail 1514 and rail 1520) is narrower than the track formed by rail 1512 and a lower portion of rail 1514. As a result, the tracks can accommodate accessories having different sized mechanism(s) for attaching to the rails of the tracks as described in more detail herein.

In an example, a lens accessory 1522 can be held by the track formed by rails 1514 and 1520. The lens accessory 1522 can include an adjustable arm 1524 for holding a lens 1526 in front of a camera of the electronic device. The camera of the electronic device can be exposed through an opening 1528 of the side 1510. The lens accessory 1522 may be movable along the track to be moved to and held at different positions in the vertical direction for suitable positioning in front of the camera. Further, the arm 1524 may be adjustable in along a horizontal direction for suitable positioning in front of the camera.

FIG. 15b illustrates another rear view of the electronic device case 1500 shown in FIG. 15a without accessories being attached.

FIG. 15c illustrates a front view of the electronic device case 1500 shown in FIGS. 15a and 15b. Referring to FIG. 15c, the lens accessory 1522 can be seen through the opening 1582. Also, an interior space 1530 defined by the body 1502 for holding an electronic device is shown. This interior space 1530 is defined by surfaces of the sides 1504, 1506, 1508, 1510, and 1511.

FIG. 15d illustrates a front view of the electronic device case 1500 with an additional accessory 1532 being attached thereto via the rails 1512 and 1514. This additional accessory 1532 is a light bar having a plurality of light emitting diodes 1534. Also, it is noted that the accessories 1516, 1522, and 1532 can be electrically daisy-chained together for electrically powering the accessories. For example, an electrical connector 1550 can electrically connect accessory 1532 to accessory 1522 such that electrical power at accessory 1532 can be provide to accessory 1522. In this figure, the battery 1518 is shown as being connected to accessory 1516 such that the accessory 1516 can receive power from the battery 1518. The accessories can be suitably moved along the rail such that their respective connectors connect together. In addition, data communication can be shared among the accessories by the same connection. In an alternative, the battery may be absent and one of the accessories may be directly connected to the electronic device, such as by a cable 1536 as described further herein.

FIG. 15e illustrates a side view of the electronic device case 1500 shown in FIG. 15d. Referring to FIG. 15e, the battery 1518 can be operatively connected to an electrical power input (not shown) of an electronic device via a cable 1536 such that the battery 1518 can power the electronic device.

FIG. 15f illustrates a bottom view of the electronic device case 1500 shown in FIGS. 15d and 15e. Referring to FIG. 15f, the accessory 1518 defines two features 1538 and 1540 attached to its underside that are shaped and sized for gripping to the protrusions 1512 and 1514, respectively. These components are fitted together for a secure hold of the accessory 1518 by the case 1500. In addition, these components permit the accessory 1518 to be moved, by adequate force, along the track such that the accessory can be positioned as desired.

FIG. 16 illustrates a rear view of an electronic device case 1600 that is similar to the electronic device case 1500 shown in FIGS. 15a-15c. The electronic device case 1600 is similar except that it does not include the rail 1520 to form the upper track with rail 1514 as with the electronic device case 1500 shown in FIGS. 15a-15c.

FIG. 17 illustrates a bottom view of the electronic device case 1600 shown in FIG. 16. Referring to FIG. 17, the rails 1512 and 1514 of the electronic device case 1600 are defined as protrusions attached to and extending from the back side 1510. In this example, the protrusions of the rails 1512 and 1514 are arcuate in shape, although it should be noted that the protrusions may alternatively be of any other suitable shape for implementing the functions of holding an accessory as described herein. Further, the protrusions of the rails 1512 and 1514 may each define a slot 1700 for engaging a corresponding protrusion of an accessory. It is noted that the rails (along with the slots of each) may extend substantially the length between an upper end and a lower end of the case 1700 such that an accessory may be placed anywhere along the length.

With continuing reference to FIG. 17, a space 1702 is defined by and between the rails 1512 and 1514. At least a portion of one or more accessories may be positioned within the space 1702 when the accessories are positioned of at least a portion of the accessory when the accessories are held by the first and second rails 1512 and 1514.

FIG. 18 illustrates a bottom view of another example electronic device case 1800. Referring to FIG. 18, this electronic device case 1800 is similar to the case 1600 shown in FIG. 17 except that the slots 1700 face an interior of the case 1800 towards the space 1702. A magnified portion A of the right side of the case 1800 is also shown in order to provide additional details.

FIGS. 19a and 19b illustrate rear views of another electronic device case 1900 that demonstratestwo (2) different locking mechanisms for holding an accessory 1902 in a desired position along a length of the case 1900 in accordance with embodiments of the present disclosure. The case 1900 is similar to the case 1600 shown in FIG. 16, but the locking mechanisms are different.

Referring to FIG. 19a, the case 1900 includes has a track with rails 1904 and 1906 such that the accessory 1902 can be moved along the track and locked into a selected position anywhere along the length of rail 1902 between its upper end 1908 and lower end 1910. In this example, the accessory 1902 is a speaker but may alternatively be any other suitable type of accessory. It is also noted that two or more accessories may be selectively positioned along the track and locked into place.

Now turning to FIG. 19b, this figure depicts a cross-sectional view of the accessory 1902 and rails 1904 and 1906 in order to show the operation of the two different locking mechanisms. Particularly, rail 1904 can utilize the resistance to movement of the accessory 1902 along the track due to friction between a surface 1912 of the rail and a surface 1914 of the accessory 1902. The surfaces 1912 and 1914 can meet when the accessory 1902 is attached to the track in the position shown (or in another position along the track). Further, by the attachment in the shown position, the surfaces can exert a force on each other or one on the other such that the upward and/or downward movement of the accessory 1902 along the track is resisted. The force(s) can be generated due to a tightness of fit of the accessory 1902 on the rail 1904, or a locking mechanism on one or both of the rail 1904 or the accessory 1902 that causes the force onto the opposing surface.

Now turning to rail 1906, this rail defines locking protrusions 1916 (or serrations) that extend along a side and length of the rail 1906 for engaging corresponding protrusions (or other suitable features) of an accessory. As shown in FIG. 19, the protrusions 1916 can engage protrusions 1918 of the accessory 1902. The protrusions 1918 of the accessory 1902 are arranged along its side. By engagement of the protrusions 1916 and 1918, the accessory 1902 can be locked and held in place at a desired position along the length of the track. Further, the protrusions 1716 and 1918 are arranged and configured to permit the accessory 1902 to be moved along the track and locked into a selected position anywhere along the length of rail 1902 between its upper end 1908 and lower end 1910.

Further, in this example, the protrusions 1916 and 1918 are arranged such that the accessory 1902 can move only in an upward direction as indicated by arrow 1920. Movement in the direction opposing the direction of arrow 1920 is resisted due to the configuration of protrusions 1916 and 1918. The accessory 1902 can be received at the lower end of the track and moved upward to a position where it is desired to lock it into place. The aforementioned friction caused by the contacting surfaces 1912 and 1914 can resist movements in the direction of double arrow 1922 and the opposing direction as shown in the close-up views of FIGS. 19c-19f.

FIGS. 20a-20c are bottom views showing a sequence of using dual locking mechanisms 200A and 200B of an accessory 201 to engage and lock onto rails 202A and 202B, respectively, of an electronic device case 204 in accordance with embodiments of the present disclosure. Referring to FIG. 20a, this figure shows the locking mechanisms 200a and 200b of the accessory 201 spaced slightly apart from rails 202A and 202B. The locking mechanisms 200a and 200b can each include a biasing component for biasing the locking mechanisms 200a and 200b in the respective positions shown in FIG. 20a. The accessory 201 is shown in FIG. 20a as being aligned such that movement in a downward direction, as indicated by arrow 206, can begin the engagement of the locking mechanisms 200A and 200B with the rails 202A and 202B, respectively, as shown in FIG. 20b for locking the accessory 201 onto the track of rails 202A and 202B.

As shown in FIG. 20b, the locking mechanisms 200A and 200B include arms 208A and 208B with features for engaging and locking onto the rails 202A and 202B, respectively. Due to engaging the rails 202A and 202B, the arms 208A and 208B are deflected a pivot about respective axes to the respective positions shown in FIG. 20b. Now turning to FIG. 20c, this figure shows full engagement with the case 204 after the accessory 201 is further moved downward. In the position of FIG. 20c, the accessory is locked to the case and the biasing mechanisms of the locking mechanism 200a and 200b cause the arms 208A and 208B to move inward for gripping to the rails 202A and 202B, respectively. One or both of top portions 210A and 210B of the arms 208A and 208B, respectively, can be moved inward to cause their lower portions to release the arms 208A and 208B from gripping the rails 202A and 202B such that the accessory 201 can be released.

FIGS. 21a-21c are bottom views showing a sequence of using dual locking mechanisms 2100 and 2102 of an accessory 201 to engage and lock onto rails 202A and 202B, respectively, of an electronic device case 204 in accordance with embodiments of the present disclosure. Referring to FIG. 21a, locking mechanism 2102 operates the same as the locking mechanism 200B shown in FIGS. 20a-20c. In contrast, locking mechanism 2100 is static and does not have moving component like the arm 208B of the locking mechanism 2102. In this example, locking mechanism 2100 is positioned as shown to lock onto rail 202A as shown in FIG. 21a. Subsequently, locking mechanism 2102 is moved downward such that the arm 208B engages the rail 202B as shown in FIG. 21b. Lastly, the arm 208B locks onto rail 202B such that the accessory 201 is locked into place.

FIG. 22 illustrates a bottom view showing another example accessory 201 with dual locking mechanisms 2100 and 2102 similar to the accessory 201 shown in FIGS. 21a-21c. Alternative to the top portion of the arm being used for moving the arm as with the example of FIGS. 21a-21c, this example utilizes a knob 2200 that can be turned by an operator for moving the arm for release of the accessory 201.

FIGS. 23a and 23b are a cross-sectional bottom view and a bottom view, respectively, of an accessory 201 with a cam locking mechanism 2300 for locking to an electronic device case 204 in accordance with embodiments of the present disclosure. Referring to FIG. 23a, cam locking mechanism 2300 includes a cam 2302 and a protrusion 2304. The cam 2302 can be moved in a direction inward to hold onto the accessory 201. Also, when the cam 2302 moves inward, the protrusion 2304 engages and locks onto rail 202B. For release, the locking mechanism 2300 can be moved outward such that the protrusion 2304 releases from the rail 202B. The locking mechanism 2100 functions similar to the locking mechanism 2100 described for the example of FIGS. 21a-21c. In FIG. 23b, the cam 2302 is hidden from view.

FIGS. 24a and 24b are a top views of an accessory 2400 with a locking mechanism with a lever 2402 for locking to an electronic device case in accordance with embodiments of the present disclosure. Referring to FIG. 24a, the lever 2402 is positioned in an upward position along the electronic device case for locking the accessory 2400 in a desired position. In order to unlock the accessory 2400 for movement of the accessory 2400 along a track of the case, the lever 2402 can be moved to the unlocked position as shown in FIG. 24b. This lever device can act as a cam to both pull and push the locking mechanism against the track, or it can be used just to unlock the accessory where a spring can pull it back to a locking position. Furthermore, when actuated, the cam can dig into or grip the track, thereby using friction or serrations to lock into place.

FIGS. 25a and 25b are a top view and a cross-sectional top view, respectively, of an accessory 2500 with dual-rotating locking mechanisms 2502 and 2504 for locking to an electronic device case 2506 in accordance with embodiments of the present disclosure. Referring to FIG. 25a, the accessory 2500 is shown locked in position at near an upper end of the case 2506. Now turning to FIG. 25b, the mechanism 2502 and 2504 each include a lever 2508 that can pivot for locking the accessory 2500 in position by engaging a feature along a respective rail 2510. An operator can push the levers 2508 to release the engagement with rails 2510. The mechanisms 2502 and 2504 may include biasing members for biasing the levers to a locked position.
