Folio including magnetic hinge for computing device

Example implementations relate to a folio including a covering portion, a flexible hinge portion, and a first magnetic element and a second magnetic element. The first magnetic element and the second magnetic element may be disposed in the flexible hinge portion. The first magnetic element may be configured to move with respect to the second magnetic element. The folio may be configured to move between an open configuration and a closed configuration such that when the folio is in the open configuration, a portion of the first magnetic element is attached to a portion of the second magnetic element, and when the folio is in the closed configuration, the portion of the first magnetic element is separated from the portion of the second magnetic element.

TECHNICAL FIELD

This disclosure relates generally to a folio, and, more particularly, to a folio for supporting a computing device.

BACKGROUND

Folios (e.g., cases, covers, sleeves, skins, etc.) used for portable computing devices may open and close having various modes, for example, a laptop mode and a tablet mode. However, during the laptop mode, the folio may not have desirable support to prevent the computing device from moving (e.g., rotating) past an upright position during use by a user. This can lead to unstable and/or unwanted collapse of the folio, particularly in the laptop mode when the computing device is not on a flat surface. Thus, a need exists for systems and apparatus to address the shortfalls of present technology and to provide other new and innovative features.

SUMMARY

In a general aspect, a folio may include a covering portion, a flexible hinge portion, and a first magnetic element and a second magnetic element. The first magnetic element and the second magnetic element may be disposed in the flexible hinge portion and the first magnetic element may be configured to move with respect to the second magnetic element. The folio may be configured to move between an open configuration and a closed configuration such that when the folio is in the open configuration, a portion of the first magnetic element is attached to a portion of the second magnetic element, and when the folio is in the closed configuration, the portion of the first magnetic element is separated from the portion of the second magnetic element.

In another general aspect, a folio may include a base portion, a covering portion, a flexible hinge portion rotatably coupled to at least one of the base portion or the covering portion, and a first magnetic element and a second magnetic element. The first magnetic element may be configured to move with respect to the second magnetic element between an engaged configuration and a disengaged configuration based on the folio being in an open configuration or a closed configuration. When the folio is in the open configuration, a portion of the first magnetic element is engaged to a portion of the second magnetic element, and when the folio is in the closed configuration, the portion of the first magnetic element is disengaged from the portion of the second magnetic element in the second position.

In another general aspect, a system may include a computing device including a display, and a folio for the computing device. The folio may include: a base portion, a covering portion, a flexible hinge portion rotatably coupled to at least one of the base portion or the covering portion, and a first magnetic element and a second magnetic element, the first magnetic element and the second magnetic element being disposed in the flexible hinge portion. The first magnetic element may be configured to move with respect to the second magnetic element. The folio may be configured to move between an open configuration and a closed configuration such that when the folio is in the open configuration, a portion of the first magnetic element is attached to a portion of the second magnetic element, and when the folio is in the closed configuration, the portion of the first magnetic element is separated from the portion of the second magnetic element.

DETAILED DESCRIPTION

In the implementations described herein, a folio (e.g., keyboard folio) (also can be referred to as an adjustable protective stand assembly) may include a base portion and a covering portion rotatably coupled via a flexible hinge portion. The folio may be configured to be in an open configuration and a closed configuration with respect to a computing device. In some implementations, the computing device described herein may be a tablet type computing device. In some implementations, the flexible hinge portion of the base portion may include a first magnetic element and a second magnetic element such that when the folio is in the open configuration, a portion of the first magnetic element is attached (e.g., engaged) to a portion of the second magnetic element. Conversely, when the folio is in the closed configuration, the same portion of the first magnetic element is separated (e.g., disengaged, detached, apart, disconnected, etc.) to the same portion of the second magnetic element. In other words, a space (e.g., gap, opening, distance, etc.) is between the portion of the first magnetic element and the portion of the second magnetic element when in the closed position. Moreover, having magnetic elements (e.g., first and second magnetic elements) in the flexible hinge portion avoids having additional elements, such as, for example, large metal hinges, tabs, etc. The folio can include an extra layer of fabric in the flexible hinge portion. As a result, this provides an efficient and smooth design of the computing device. In addition, the overall thickness of the computing device is not (or may not be) impacted because the magnetic elements are disposed in the flexible hinge portion, rather than other portions (e.g., covering portion and/or electronic device) of the computing device.

Further, the devices described herein can have advantages over, for example, conventional folios for a computing device where the folio cannot support the computing device in desirable a laptop mode without collapsing or flexing. In other words, the folio described herein can support the computing device and can have stability during the laptop mode. For example, the folio described herein can support the computing device from moving (e.g., rotating) past an upright position (e.g., approximately 110°). In addition, the folio described herein can also easily be converted into a tablet mode by being rotatably moved around via the flexible hinge portion.

FIGS. 1A through 1Dare schematic diagrams of an embodiment of a folio100.FIG. 1Billustrates a closed configuration (or closed mode) of the folio100,FIG. 1Cillustrates an open configuration (or a laptop mode) of the folio100, andFIG. 1Dillustrates a tablet configuration (or tablet mode) of the folio100. The folio100can be configured to be coupled to a computing device (e.g., a tablet, a mobile device, etc.).

As shown inFIGS. 1A through 1D, the folio100may include a base portion110and a covering portion120. In some implementations, the base portion110may be hingedly coupled to the covering portion120via a flexible hinge portion125. The base portion110may include a first surface portion117and a second surface portion119, opposite the first surface portion117. In one example implementation, the first surface portion117can be defined as a top surface and the second surface portion119can be defined as a bottom surface. The covering portion120may include a first surface portion127and a second surface portion129, opposite the first surface portion127. In one example implementation, the first surface portion127can be defined as a top surface and the second surface portion129can be defined as a bottom surface. In some implementations, the covering portion120may overlay or cover the base portion110in the closed configuration. In other words, the covering portion120may include a size and shape that is similar to a size and shape of the base portion110.

In some implementations, when in the open configuration, as shown inFIG. 1C, the base portion110is not in contact with and/or is not aligned parallel to (e.g., is non-parallel to) the covering portion120. More specifically, the first surface portion117(top surface) of the base portion110does not face and/or is not in contact with the first surface portion127(top surface) of the covering portion120.

In some implementations, when in the closed configuration, as shown inFIG. 1B, the base portion110can be aligned parallel with respect to the covering portion120. More specifically, the first surface portion117(top surface) of the base portion110faces and/or is in contact with the first surface portion127(top surface) of the covering portion120.

In some implementations, when in the tablet configuration, as shown inFIG. 1D, the base portion110can be aligned parallel with respect to the covering portion120. More specifically, the second surface portion119(bottom surface) of the base portion110faces and/or is in contact with the second surface portion129(bottom surface) of the covering portion120. To describe this in a different manner, in comparison to the closed configuration ofFIG. 1B, the tablet configuration is rotated in an opposite direction. For example, in the closed configuration, the covering portion120can rotate 180° in a first direction towards the first surface portion117(top surface) of the base portion110, and in the tablet configuration, the covering portion120can rotate 180° in a second direction, opposite the first direction, towards the second surface portion119(bottom surface) of the base portion110. Further, in use, in the tablet configuration, a user flips (e.g., rotates 180°) the folio100such that a computing device (not shown), which can be coupled to folio100, is facing the user.

In some implementations, the flexible hinge portion125may include a magnetic element130configured to lock (e.g., engage) the folio100in place or in a more rigid position than within the magnetic element130. More specifically, the magnetic element130can hold the folio100with sufficient stability that it prevents and/or reduces the computing device (not shown) from moving (e.g., rotating, flopping over) unexpectedly. In addition, use of the magnetic element130in the flexible hinge portion125avoids the use of mechanical fasteners for attaching the base portion110and the covering portion120together.

Referring back toFIG. 1A, the magnetic element130may extend between a first end portion111to a second end portion112of the flexible hinge portion125. In some implementations, the magnetic element130may extend from the first end portion111to the second end portion112of the flexible hinge portion125.

In some implementations, the magnetic element130can include several elements. For example, as shown inFIGS. 1B through 1D, there may be a first magnetic element130aand a second magnetic element130bdisposed in the flexible hinge portion125. Besides two magnetic elements130a,130b, example embodiments as described herein can also support having two or more magnetic elements.

Each of the magnetic elements130a,130bprovides a magnetic attractive force that causes the magnetic elements130a,130bto attach to each other. In other words, each of the magnetic elements130a,130bcan include an attachment feature to provide certain magnetic properties to support the folio100from rotating or flopping over in an undesirable fashion. For example, referring toFIG. 1C, when the folio100is in the open configuration, a portion of the first magnetic element130acan be attached (e.g., engaged) to a portion of the second magnetic element130b, as shown in enlarged circle A. In other words, the portion of the first magnetic element130acan be cooperatively engaged to the portion of the second magnetic element130bbased upon the magnetic properties, which results in the magnetic elements130a,130battaching to each other in a desired and repeatable manner. Due at least in part to the cooperative nature of the interaction of the magnetic fields, the magnetic elements130a,130bcan attach to each other in a pre-determined position and relative orientation without external intervention. In some implementations, the pre-determined position of the magnetic elements130a,130bcan be in a linear configuration (e.g., along a same planar surface). Although not shown inFIG. 1C, the folio100(and associated computing device (e.g., tablet)) can be in a laptop configuration when the magnetic elements130a,130bare engaged as shown inFIG. 1C.

In some implementations, the magnetic elements130a,130bcan remain in the magnetically attached state until a releasing force of sufficient magnitude is applied that overcomes an overall net attractive magnetic force. For example, referring toFIG. 1B, when the folio100is in (e.g., is moved to) the closed configuration, the same portion of the first magnetic element130acan be separated (e.g., detached) to the same portion of the second magnetic element130b, as shown in enlarged circle B. In other words, the same portion of the first magnetic element130acan be disengaged to the same portion of the second magnetic element130bforming a gap189(e.g., space, distance, etc.) (shown in enlarged circle B) therebetween. In this configuration, the magnetic interaction between the magnetic elements130a,130bcan be reduced. In other words, the magnetic force between the first magnetic element130aand the second magnetic element130bin the closed configuration ofFIG. 1Bis weaker as compared to the magnetic force between the first magnetic element130aand the second magnetic element130bwhen the folio100is in the open configuration ofFIG. 1C.

In other implementations, referring toFIG. 1D, when the folio100is in (e.g., moved to) the tablet configuration, the same portion of the first magnetic element130acan be separated (e.g., detached) to the same portion of the second magnetic element130b, as shown in enlarged circle C. Hence, the same portion of the first magnetic element130acan be disengaged to the same portion of the second magnetic element130bforming a gap191. In this case, when comparing the configuration ofFIG. 1B, the magnetic elements130a,130bare in an opposite configuration. More specifically, the second magnetic element130bis on top (rather than the bottom) and the first magnetic element130ais on bottom (rather than the top). This is due to the covering portion120being rotated towards the second surface portion119(bottom surface) of the base portion110.

In some implementations, the flexible hinge portion125can include a first fabric layer135aand a second fabric layer135b. In some implementations, the first fabric layer135acan face the second fabric layer135b. In other words, the second fabric layer135bcan be disposed on the first fabric layer135a, as shown inFIG. 1C. The first fabric layer135aand the second fabric layer135bcan be composed of a material that can be bent (e.g., wrinkled, curved, twisted, etc.) to provide necessary flexibility to open and close the folio100. In some implementations, the first fabric layer135aand/or the second fabric layer135bmay be composed from various materials, such as, for example, silicone, rubber, polyurethane, thermoplastic polyurethane (“TPU”) and/or various other materials. In some implementations, the first fabric layer135aand/or the second fabric layer135bcan be made from the same material as a material of the covering portion120.

In some implementations, the magnetic element130(e.g., the first magnetic element130aand the second magnetic element130b) can be fixedly coupled to the first fabric layer135aand/or the second fabric layer135b. In some implementations, a portion (e.g., a lower portion) of the magnetic element130can be fixedly coupled to the first fabric layer135aand/or the second fabric layer135b. In other implementations, a portion (e.g., an upper portion) of the magnetic element130can be fixedly coupled to the first fabric layer135aand/or the second fabric layer135b. In some implementations, both portions (e.g., the upper and lower portions) of the magnetic elements130can be fixedly coupled to the first fabric layer135aand/or the second fabric layer135b.

In some implementations, the magnetic elements130can be rigid as compared to the flexible hinge portion125to which the magnetic elements130are attached in the flexible hinge portion125. In other words, the magnetic elements130can be affixed (e.g., attached) to the flexible hinge portion125while the flexible hinge portion125bends.

In some implementations, the magnetic element130can be fixedly coupled to the first fabric layer135aand/or the second fabric layer135bvia an adhesive or glue, for example. Other fastening means may be employed to attach the magnetic element130to the first fabric layer135aand/or the second fabric layer135b, such as, for example, sewn into the first fabric layer135aand/or the second fabric layer135b.

Because the magnetic element130is fixedly coupled to the first fabric layer135aand/or the second fabric layer135bof the flexible hinge portion125, the magnetic element130may move in accordance to how the flexible hinge portion125is rotated. For example, when the folio100is in the closed configuration (or the tablet configuration), the flexible hinge portion125folds (e.g., bends, curves, twists), which causes the first magnetic element130aand the second magnetic element130bto separate (e.g., disengage, detach, disconnect) from the first fabric layer135aand/or the second fabric layer135b, due to the first magnetic element130aand the second magnetic element130bbeing attached at a bend portion of the flexible hinge portion125. In other words, the first fabric layer135aand the second fabric layer135bshould be composed of a material that can be bent to provide necessary flexibility to allow for the magnetic element130(and components thereof) to change between an engaged configuration and disengaged configuration.

In some implementations, the covering portion120can include a rigid material. The rigid material can employ, in some implementations, properties to maintain a flat configuration, and/or provide structural support of the covering portion120. In one example implementation, the rigid material may be composed from a glass fiber material, for example. Other materials may be used, such as, for example, polypropylene plastic, corrugated polymeric material, compressed wood fiber, or metal sheet. In some implementations, the rigid material may be covered with a fabric layer (not shown) for added protection and/or appearance.

Other layers may be included to form the covering portion120, such as, for example, a support layer and/or a resilient layer (not shown). The support layer may add strength and stronger construction of the covering portion120. The resilient layer may absorb energy if the folio100is dropped onto a hard surface. In addition, the support layer and/or the resilient layer can protect components inside of the covering portion120from damage due to drops, impacts, vibrations and/or compression loads.

FIGS. 2A through 2Gillustrate a folio200according to example implementations. The folio200shown inFIGS. 2A-2Gis a variation of the folio100shown inFIGS. 1A through 1D. Like elements will use similar reference numbers.FIG. 2Ais a perspective view of the folio200in an open configuration;FIGS. 2B-2Dare partial perspective views of the folio200in the open configuration (or the laptop configuration);FIG. 2Eis a side view, when viewed from a right side of the folio200; andFIGS. 2F and 2Gare perspective views of the folio200in a closed configuration.

Referring toFIG. 2A, the folio200includes a base portion110that is in an open position with respect to the covering portion120according to an example implementation. In some implementations, the base portion110may be generally rectangular shaped having two long sides (e.g., a right side end portion101aand a left side end portion101b) and two short sides (e.g., a proximal side end portion103aand a distal side end portion103b). The base portion110can be other shapes, such as, for example, a square. Further, corners121of the base portion110can be curved (e.g., rounded, smooth, etc.) so as to protect the base portion110from damage due to impact when compared to a sharp edge corner. Further, the curved corners121can provide an aesthetically pleasing look and/or feel to the folio200.

In some implementations, the covering portion120may be generally rectangular shaped having two long sides (e.g., a right side portion105aand a left side portion105b) and two short sides (e.g., a proximal side portion107aand a distal side portion107b). The covering portion120can be other shapes, such as, for example, a square. Further, corners122of the covering portion120can also be curved (e.g., rounded, smooth, etc.) so as to protect the covering portion120from damage due to impact when compared to a sharp edge corner.

In some implementations, a shape of the covering portion120may correspond (e.g., substantially match) to a shape of the base portion110. As a result, edges of the covering portion120are in-line (e.g., flush, even) with edges of the base portion110. In some implementations, the edges of the base portion110and/or covering portion120can have a chamfered or beveled edge.

In some implementations, the covering portion120can be coupled to a computing device205(as shown inFIG. 4). The computing device205may include a tablet computer. The computing device205may also include a laptop computer, a notebook computer or other type of computing device, such as, for example, a cellular phone, a media player, mobile device, or other handheld or portable electronic devices. Other configurations may be used for the computing device205if desired. The example ofFIG. 4is merely illustrative.

Referring toFIG. 2A, the covering portion120may be rotatably attached to the base portion110via the flexible hinge portion125. The rotatable attachment of the covering portion120to the base portion110, and/or the base portion110to the covering portion120, may enable the covering portion120to rotate to the open position, in which the covering portion120is not in contact with the base portion110, and/or in which the covering portion120is rotated at an angle away from the base portion110. In some implementations, the covering portion120can rotate 180° (e.g., approximately 180°) in a first direction away from the base portion110or can rotate 180° (e.g., approximately) 180° in a second direction, opposite the first direction, towards the base portion110. In other implementations, the covering portion120can rotate approximately 360° (e.g., approximately 360°) towards the rear surface portion119of the base portion110. This configuration can be defined as a tablet mode.

In some implementations, the base portion110may include an input device131. For example, the input device131may include at least a keyboard142and a touch-sensitive input device143(e.g., touch pad). In the opened configuration, the rotated cover portion120exposes the keyboard142and/or the touch-sensitive input device143disposed on the first surface portion117of the base portion110.

The touch-sensitive input device143may be used to track movements of the user's finger on a surface of the touch-sensitive input device143by detecting the position (e.g., (x,y) coordinates) of the user's finger on the surface of the touch-sensitive input device143as the user's finger moves across the surface of the touch-sensitive input device143. The computing device205(as shown inFIG. 4) may implement gesture recognition software that translates the detected positions of the user's finger into a gesture (e.g., pointer movement, scroll, etc.).

In some implementations, the base portion110may include a housing150(e.g., enclosure, casing, etc.) to house various structures and electronic components (not shown) inside of the base portion110. For example, the housing150may enclose an integrated circuit chip, a printed circuit board (PCB), a micro-processor, a memory, cables, connectors, etc. In some implementations, the housing150may be formed as a unitary structure. In other words, the housing150may be a one-piece structure. In some implementations, the housing150can be formed of non-magnetic material, such as, a plastic material or various composite polymers, for protecting the subsystem and components disposed within the housing150. In some implementations, the housing150can be formed from non-ferrous metals, such as, aluminum or non-magnetic stainless steel, for example.

In some implementations, as shown inFIG. 2D, the housing150may be formed as separate structures. In this regard, the housing150may include a first housing portion153and a second housing portion155forming an enclosure. In an example implementation, the first housing portion153may be defined as a top housing and the second housing portion155may be defined as a bottom housing.

In some implementations, the first housing portion153and the second housing portion155can be molded and/or otherwise formed from a polymeric material, for example. In some implementations, the first housing portion153and the second housing portion155can be joined together by a snap-fit, press-fit, fasteners and/or any other suitable attachment method. For example, the first housing portion153and the second housing portion155can be attached via fastening means (e.g., screws) inserted into corresponding screw bosses (not shown).

In some implementations, as shown inFIG. 2D, the covering portion120may be comprised of structural components having combinations of layers. For example, the covering portion120may include a rigid layer175, a first fabric layer181, and a second fabric layer182. In this example implementation, the first fabric layer181may be defined as a top surface layer and the second fabric layer182may be defined as a bottom surface layer. The rigid layer175can be provided between the first fabric layer181and the second fabric layer182. The rigid layer175can be made from a material that maintains the flat configuration and/or provide structural support. In one example implementation, the rigid layer175may be made from a glass fiber material, for example.

In some implementations, the first fabric layer181and/or the second fabric layer182may be composed from various materials, such as, for example, silicone, rubber, real or fake leather, polyurethane, thermoplastic polyurethane (a type of plastic typically referred to by its acronym, “TPU”) and various other configurations. In some implementations, the first fabric layer181and/or the second fabric layer182may further include abrasion-resistance properties. In this regard, the first fabric layer181and/or the second fabric layer182may include a relatively high coefficient of friction (e.g., anti-slipping surface), which may limit or prevent movement of the folio200against a surface. In some implementations, the first fabric layer181and/or the second fabric layer182may include a micro-fiber to prevent and/or reduce damage to a display (not shown) of a computing device. In some implementations, each of the fabric layers181and182may be made from the same material. In other implementations, the first fabric layer181may be made from a different material with respect to the second fabric layer182.

Other layers may be included to form the covering portion120, such as, for example, a support layer and/or a resilient layer (not shown). The support layer may add strength and stronger construction of the covering portion120. The resilient layer may absorb energy if the folio200is dropped onto a hard surface. In addition, the support layer and/or the resilient layer can protect components inside of the covering portion120from damages due to drops, impacts, vibrations and/or compression loads.

In some implementations, the base portion110may include a support layer and/or a resilient layer to protect components inside of the base portion110from damage due to drops, impacts, vibrations and/or compression loads.

In some implementations, the covering portion120may be formed with multiple segments that may be foldable by way of fold regions formed between the segments. For example, referring toFIG. 2A, the covering portion120may include a first segment243, a second segment244, and a third segment245. Each of the first segment243, the second segment244, and the third segment245may be foldable or rotatable with respect to the remaining segments by way of fold regions251,252between adjacent segments243,244,245. In this example configuration, the fold region251can be disposed between the first segment243and the second segment244, and the fold region252can be disposed between the second segment244and the third segment245. In some implementations, the covering portion120may be folded into several distinct folded configurations. For example, the segments243,244,245can be rotated or folded to arrange the covering portion120in an open mode, a closed mode, a laptop mode, a tablet mode, etc.

In some implementations, the covering portion120may include an attachment element (not shown) which may be configured to attach the respective segments243,244,245to each other. In this regard, the attachment element may include, for example, magnetic element(s) to attach the segments243,244,245in various folded configurations. In some implementations, the attachment element may be embedded in each of the first segment243, the second segment244, and the third segment245. In other implementations, the attachment element may be mechanical fasteners, such as, for example, clips, hook-and-look fasteners, screws, clamps, or pins, and/or adhesive, tape, or glue.

FIGS. 2B and 2Care schematic diagrams of a portion (including a cross-sectional view) of the exemplary folio200. In these figures, close-up views of the flexible hinge portion125of the folio200are shown.

Referring toFIG. 2B, the flexible hinge portion125may include a magnetic element230to lock the folio200in place (e.g., in a laptop configuration). Alternatively, the magnetic element230may also have a similar configuration in an open configuration. More specifically, the magnetic element230in the open configuration and in the laptop configuration will be the same because the covering portion120(e.g., the first segment244) in the open configuration and in the laptop configuration has the same position with respect to the base portion110. The magnetic element230in the laptop mode holds the folio200with sufficient stability that it prevents and/or reduces the computing device205(as shown inFIG. 4) from rotating or flopping over in an undesirable fashion.

In some implementations, as shown inFIG. 2A, the magnetic element230may extend from a first end portion211to a second end portion212of the flexible hinge portion125. To describe this in another manner, the magnetic element230may extend in a direction along longitudinal line A1-A1. For clarity sake,FIG. 2Bis only a partial view of the folio200ofFIG. 2A, and thus, illustrates the magnetic element230extending from the first end portion211to a portion215(e.g., middle portion) of the flexible hinge portion125along the longitudinal line A1-A1. The middle portion215can be an area of the flexible hinge portion125that is between the first end portion211and the second end portion212.

In some implementations, as shown inFIG. 2C, the magnetic element230can be made up of several parts that extend along the longitudinal line A1-A1. In other words, the magnetic element230can be made up of several members instead of a continuous one-piece member, as shown inFIG. 2B. In this regard, an arrangement of a plurality of magnetic elements230can be disposed in the flexible hinge portion125in a serial configuration (e.g., a regular succession along a line). In other words, the plurality of magnetic elements230can be arranged one after the other, in a row, consecutively, from the first end portion211to the second end portion212along the longitudinal line A1-A1.

In some implementations, the magnetic element230can be made up of a first magnetic element230aand a second magnetic element230bdisposed in the flexible hinge portion125. The first magnetic element230aand the second magnetic element230bcan provide magnetic attractive forces that cause the first magnetic element230aand the second magnetic element230bto attach to each other. In other words, each of the first magnetic element230aand the second magnetic element230bcan include an attachment feature to provide certain magnetic properties to support the folio200from rotating or flopping over unexpectedly. For example, when the folio200is in the open configuration (or the laptop configuration), the first magnetic element230aand the second magnetic element230bcan cooperatively engage (e.g., interlock) based upon the magnetic properties, which results in a portion of the first magnetic element230aand a portion of the second magnetic element230battaching to each other in a desired and repeatable manner. Due at least in part to the cooperative nature of the interaction of the magnetic fields, the portion of the first magnetic element230aand portion of the second magnetic element230bcan attach to each other in a pre-determined position and relative orientation without external intervention. In some implementations, the cooperative magnetic interaction can result in the portion of the first magnetic element230aand the portion of the second magnetic element230bto self-align and self-center in a desired orientation.

In some implementations, the first magnetic element230aand the second magnetic element230bcan remain in the magnetically attached state until a releasing force of sufficient magnitude is applied that overcomes the overall net attractive magnetic force. For example, when the folio200is in the closed configuration (or the tablet configuration), the same portions of the attached magnetic elements230a,230bcan separate (e.g., disengage, detach) such that the magnetic interaction between the magnetic elements230a,230bcan be reduced. In other words, the magnetic force between the same portion of the first magnetic element230aand the same portion of the second magnetic element230bin the closed configuration is weaker as compared to the magnetic elements230a,230bin the open configuration (or laptop configuration). In other implementations, when the folio200is in the closed configuration, the magnetic interaction between the same portion of the first magnetic element230aand the same portion of the second magnetic element230bcan be non-existent or relatively weak. In other words, there is no magnetic interaction present between the same portion of the first magnetic element230aand the same portion of the second magnetic element230b. In this case, the first magnetic element230aand the second magnetic element230bcan be completely detached (e.g., no portions of the magnetic elements230a,230bcontacting each other).

In some implementations, the first magnetic element230aand the second magnetic element230bcan have a shape and/or form that can interlock to each other. The term “interlock” herein describes the first magnetic element230aand the second magnetic element230bhaving a characteristic to join (e.g., interconnect, link, etc.) to each other. In other words, the portion of the first magnetic element230abeing in an attached state to the portion of the second magnetic element230b. Further, due to the particular shape of the first magnetic element230aand/or the second magnetic element230b, there may be more surface area that cooperatively engage (e.g., contact) between the magnetic elements230a,230b. This can cause the magnetic interaction (e.g., net attractive magnetic force) between the first magnetic element230aand the second magnetic element230bto be stronger.

In some implementations, at least one surface of the first magnetic element230aand/or the second magnetic element230bcan be a straight planar surface. In other words, the surface can be flat. A flat planar surface can create a magnetic attractive force that is greater than a non-planar surface (e.g., curve). In some implementations, all of the surfaces of the first magnetic element230aand/or the second magnetic element230bcan have straight planar surfaces (e.g., flat).

Referring toFIGS. 2D and 2E, a shape of the first magnetic element230aand/or the second magnetic element230bcan be planar (e.g., lying in one plane; flat) or non-planar (e.g., lying in more than one plane). In one example implementation, the first magnetic element230acan be planar and the second magnetic element230bcan be non-planar. In other words, the first magnetic element230ahas a generally rectangular shape and the second magnetic element230bhas a generally S-like shape, when viewing at a side view. To describe this in another manner, the second magnetic element230bcan partially lay over (e.g., surround) the first magnetic element230a. Due to the particular shapes of the magnetic elements230a,230b, as illustrated herein, this provides a device having an interlocking structure.

Referring toFIGS. 3A through 3E, the magnetic elements230a,230bcan have other varying shapes (e.g., cross-sectional shapes) and sizes. In various implementations, as shown inFIGS. 3A through 3E, which are cross-sectional views when viewed from a side, the magnetic elements230a,230bmay have other shapes and/or sizes, besides the one illustrated inFIG. 2D. For example, as described in example embodiments,FIG. 3Aillustrates the first magnetic element230abeing substantially rectangular shaped and the second magnetic element230bbeing substantially S-shaped. In comparison to the second magnetic element230bas shown inFIG. 2D, the second magnetic element230bofFIG. 3Acan extend to an end portion of the first magnetic element230asuch that edges of the magnetic elements230a,230bmatch (e.g., flush). In another example,FIG. 3Billustrates the first magnetic element230abeing substantially S-shaped and the second magnetic element230bbeing substantially S-shaped. In another example, as shown inFIG. 3C, the first magnetic element230abeing substantially L-shaped and the second magnetic element230bbeing generally rectangular shaped. In another example, as shown inFIG. 3D, the first magnetic element230abeing substantially L-shaped and the second magnetic element230bbeing substantially L-shaped. In this example, the two magnetic elements230a,230bare in an inverse mirror image (e.g., flipped reverse image). In another example, as shown inFIG. 3E, the first magnetic element230abeing substantially L-shaped (shortened) and the second magnetic element230bbeing substantially S-shaped. The above described examples are merely general representations of shapes and sizes, and not limited to the ones described herein.

Referring back toFIG. 2D, the flexible hinge portion125may include a first fabric layer255and a second fabric layer257. In one example implementation, the first fabric layer255can be defined as a top fabric layer and the second fabric layer257can be defined as a bottom fabric layer. Having two fabric layers255,257may strengthen or reinforce (e.g., stiffen) the flexible hinge portion125. The first and second fabric layers255,257may be coupled to the base portion110and/or the covering portion120. For example, one end of the first and second fabric layers255,257can be attached to the base portion110and other end of the first and second fabric layers255,257can be attached to the covering portion120. In some implementations, as shown inFIG. 2D, the ends of the first and second fabric layers255,257that are attached to the base portion110can be attached between the first housing153and the second housing155of the base portion110.

In some implementations, the flexible hinge portion125can include more than two first and second fabric layers255,257. For example, a third fabric layer can be attached to the first fabric layer255. In another example, a third fabric layer can be attached to the second fabric layer257. In another example, a third fabric layer can be attached to the first fabric layer255and a fourth fabric layer can be attached to the second fabric layer257.

In some implementations, the first and second fabric layers255,257can be attached to the base portion110and/or the covering portion120using adhesive or glue, for example. Other fastening means may be used to attach the first and second fabric layers255,257to the base portion110and/or the covering portion120, such as, for example, welding, press fitting or friction fitting, etc. The attachment feature of the first and second fabric layers255,257should be sufficient (strong enough) to bend the first and second fabric layers255,257in both directions (e.g., away from the base portion110or towards the base portion110) without detaching from the base portion110and/or the covering portion120.

In some implementations, the first and second fabric layers255,257may be composed from various materials, such as, for example, silicone, rubber, real or fake leather, polyurethane, thermoplastic polyurethane (“TPU”) and various other configurations. In some implementations, each of the first and second fabric layers255,257may be made from the same material. In other implementations, the first fabric layer255may be made from different material from the second fabric layer257. In some implementations, at least one of the first and second fabric layers255,257can be made from the same material as at least one of the fabric layers181,182of the covering portion120.

In some implementations, the second fabric layer182of the covering portion120can be made part of the flexible hinge portion125. In other words, the second fabric layer182can be attached to the second fabric layer257in the flexible hinge portion125. For example, the second fabric layer182can be attached to the second fabric layer257via an adhesive262. The second fabric layer182can be used to protect the first and second fabric layers255,257from damages (e.g., breakage, tears, slits, etc.). In some implementations, the second fabric layer182can be attached to the base portion110. In this regard, an end portion of the fabric layer182, along with the end portions of the first and second fabric layers255,257, can be attached to the base portion110. In some implementations, the end portion of the fabric layer182can be disposed between the first housing member155and the second housing member157of the base portion110.

Referring toFIG. 2E, which is a side view, taken along view X-X ofFIG. 2A, the first and second magnetic elements230a,230bmay be disposed between the first fabric layer255and the second fabric layer257. In some implementations, the first and second magnetic elements230a,230bmay be removably coupled to the first fabric layer255and/or the second fabric layer257. For example, one or both of the first and second magnetic elements230a,230bmay be removably coupled to the second fabric layer257. More specifically, a portion234of the first magnetic element230aand a portion235of the second magnetic element230bcan be removably coupled to second fabric layer257. In other implementations, at least one of the first and second magnetic elements230a,230bmay be removably coupled to the first fabric layer255. For example, a portion237of the second magnetic element230bcan be removably coupled to the first fabric layer255. In other implementations, at least one of the first and second magnetic elements230a,230bmay be removably coupled to both of the first fabric layer255and second fabric layer257. For example, the portion235of the second magnetic element230band the portion237of second magnetic element230bcan be removably coupled to the second fabric layer257and the first fabric layer255, respectively. The above described examples are merely general representations of the various attachment features, and may further vary depending on the shapes and sizes of the magnetic elements.

In some implementations, the first and second magnetic elements230a,230bcan be removably coupled to the first and second fabric layers255,257in a region that is generally middle (or middle portion) of the flexible hinge portion125. In other words, when viewing at a side view, as shown inFIG. 2E, the first and second magnetic elements230a,230bare removably attached to at least one of the first and second fabric layers255,257approximately in a region F of the flexible hinge portion125. To describe this in another manner, the region F may be defined as a bending portion of the flexible hinge portion125. The bending movement of the flexible hinge portion125causes the first and second magnetic elements230a,230bto move with respect to each other, which will be described in detail later.

In some implementations, the first and second magnetic elements230a,230bcan be attached to at least one of the first and second fabric layers255257via an adhesive or glue, for example. Other fastening means may be employed to attach the first and second magnetic elements230a,230bto the first and second fabric layers255,257, such as, for example, sewn into the first and second fabric layers255,257.

FIGS. 2F and 2Gare diagrams of the folio200in an example closed configuration.FIG. 2Fis a side view of a portion of the flexible hinge portion125ofFIG. 2Aaccording to an example implementation. As shown inFIG. 2F, the covering portion120can be rotated (e.g., 180°) towards the base portion110(as shown by arrow B inFIG. 2E) so as to bend the flexible hinge portion125. In other words, the covering portion120can be rotated such that the covering portion120is aligned parallel with respect to the base portion110, which illustrates a closed configuration.

Due to the first and second magnetic elements230a,230bbeing attached at the bending portion of the flexible hinge portion125, this causes the first and second magnetic elements230a,230bto move (e.g., separate, detach) from each other. For example, as shown inFIG. 2G, an end portion271of the first magnetic element230acan be separated (e.g., disengaged, detached) from an end portion272of the second magnetic element230b.

Referring toFIG. 2G, which is an enlarged view of an area associated with portion Y shown inFIG. 2F, a distance H is formed between the separated magnetic elements230a,230b. Alternatively, the distance H can be defined as an opening, a gap, a space, etc.

Because of the contour (e.g., radius of curvature) of the flexible hinge portion125when the flexible hinge portion125is bent, the distance H may be larger than at other orientations of the folio200(e.g., laptop configuration or open configuration). For example, distance H may be at the largest distance when the folio200is in the closed configuration and becomes smaller as the folio200is converted into the laptop configuration or open configuration. In contrast, in the laptop configuration or open configuration, no distance H is provided between the first and second magnetic elements230a,230bdue to the first and second magnetic elements230a,230bbeing interlocked and attached together. Further, in the closed configuration, the magnetic interaction between the first and second magnetic elements230a,230bcan be reduced and/or non-existence. In some implementations, no magnetic interaction force can be present between the first and second magnetic elements230a,230bso that the covering portion120can remain closed with respect to the base portion110.

In some implementations, when the folio200is in the open configuration (or the laptop configuration), the covering portion120can be rotated (e.g., 180°) in a direction away from the base portion110. In other words, the covering portion120can be rotated such that the covering portion120may be straight or approximately straight (i.e., not bent, flexed, or rotated) with respect to the base portion110. To describe this in another manner, the flexible hinge portion120may be flattened out (i.e., arranged such that the covering portion120and the base portion110may be oriented on or substantially on the same plane). In this example implementation, a portion of the first magnetic element230aand a portion of the second magnetic elements230bcan be attached together so that no distance H is provided between the portion of the first magnetic element230aand the portion of the second magnetic elements230b. In other words, the portion of the first magnetic element230acan be attached and interlocked with the portion of the second magnetic elements230b. For example, the end portion271of the first magnetic element230acan be attached to the end portion272of the second magnetic element230bwhen the respective portions are brought into proximity to each other. In this implementation, the magnetic force between the portion of the first magnetic element230aand the portion of the second magnetic elements230bis at their strongest, and can remain in the magnetically attached state until a releasing force of sufficient magnitude is applied that overcomes the overall net attractive magnetic force. In some implementations, the first and second magnetic elements230a,230bcan be attached to each other in a pre-determined position and relative orientation without external intervention.

In some implementations, when the folio is in the tablet configuration (not shown), the covering portion120can be rotated (e.g., 180°) in a direction towards the base portion110(as shown by arrow D inFIG. 2E) so as to bend the flexible hinge portion125. In other words, the covering portion120can be rotated such that the covering portion120is aligned parallel with respect to the rear surface119(as shown inFIG. 1D) of the base portion110. In this example implementation, similar to the closed configuration, a portion of the first magnetic element230aand a portion of the second magnetic elements230bcan move (e.g., separate, detach) from each other. For example, an end portion275of the second magnetic element230bcan be separated (e.g., disengaged, detached) from a surface portion277of the first magnetic element230a. As a result, this creates a gap (e.g., an opening, a space) (not shown) between the first magnetic element230aand the second magnetic element230bwhen the folio200is in the tablet configuration. Due to the separation of the first and second magnetic elements230a,230b, the magnetic interaction between the first and second magnetic elements230a,230bcan be reduced and/or non-existence.

FIG. 4is a schematic diagram of the folio200in an exemplary laptop configuration. In this example implementation, the covering portion120may be folded into a distinct folded configuration so as to view the computing device205in a laptop mode. For example, the second segment244of the covering portion120can be rotated or folded in a first direction (e.g., towards the base portion110) via the fold region251such that the second segment244of the covering portion120is at an angle 45° or approximately 45° with respect to the first segment243of the covering portion120. The third segment245of the covering portion120can then be rotated or folded in a second direction, opposite the first direction (e.g., away from the base portion110) via the fold region252such that the third segment245of the covering portion120is at an angle 20° or approximately 20° with respect to the second segment244of the covering portion120. The rotation angles may vary depending on the user's preference and viewing angle.

In some implementations, the third segment245of the covering portion120may be configured to move (e.g., slide) along a portion of a rear surface306of the computing device205. For example, the third segment245may slide along a translational axis in a translational direction (indicated by “T”). For purposes of this description, the sliding along the translational axis will be described from a point of view of view looking at a front surface304of the computing device205when the computing device205is in a landscape orientation (i.e., a larger dimension of a display301is oriented horizontally). Some implementations are possible in which the translational axis is different or the computing device205is oriented differently. The translational axis may for, example, be aligned with a vertical axis of the computing device205when the computing device205in in a landscape orientation. A first translational direction may be directed from a bottom side (i.e., the side below the display301) of the computing device205to a top side (i.e., the side above the display301) of the computing device205, and a second translation direction may be directed in the opposite direction (i.e., from the top of the computing device205to the bottom).

In some implementations, the third segment245of the covering portion120may be magnetically coupled to at least a portion of the rear surface306. In this regard, the third segment245of the covering portion120may include a magnetic material and the rear surface306may include one or more magnetically susceptible regions to attract the magnetic material of the third segment245of the covering portion120. The magnetically susceptible regions of the rear surface306may be formed from magnetically susceptible materials. In some implementations, the magnetically susceptible regions of the rear surface306are not formed from magnetically susceptible materials but are instead in close proximity to magnetically susceptible materials. For example, the rear surface306may be formed from a magnetically inert material (e.g., a polymer or non-magnetic metal) but a magnetically susceptible material may be disposed inside the computing device205near or adjacent to the rear surface306.

In some implementations, the magnetically susceptible region of the rear surface306may extend from a lower position on the rear surface306to a higher position on the rear surface306. The third segment245of the covering portion120may then slide between a bottom and a top of the rear surface306and may be positioned at the bottom, the top, or anywhere in between. As the third segment245of the covering portion120moves in the translation direction T along the rear surface306, the second segment244of the covering portion120will rotate with respect to the first segment243of the covering portion120as will the computing device205. In this manner, a user can adjust the viewing angle of the display301. For example, as the third segment245of the covering portion120moves down toward the bottom of the rear surface306, the computing device205rotates to a more upright angle. Conversely, as the third segment245of the covering portion120moves up toward the top of the rear surface306, the computing device205rotates to a more horizontal angle. Because the third segment245of the covering portion120can be adjusted to numerous positions within the magnetically susceptible region, the computing device205can be rotated to numerous angles. In other words, the folio200may allow for numerous adjustments to the angle of the computing device205.

A magnetic material may be a material that produces a magnetic field. For example, a magnetic material may produce a magnetic field independent of any contemporaneous external magnetic field. In some implementations, an external magnetic field is applied during the formation of a magnetic material and then the magnetic field of the magnetic material persists after removal of the external magnetic material. Magnetic materials may produce magnetic fields having a field strength of at least 5 gausses. The magnetic moments of the electrons of a magnetic material may be substantially coordinated so that the magnetic moments point in the same direction.

A ferromagnetic material may be a material having a high susceptibility to magnetization. Some ferromagnetic materials may also be magnetic materials. For example, a ferromagnetic material may form a magnetic material or may be attracted to a magnetic material. Examples of ferromagnetic materials include, but are not limited to, iron, nickel, cobalt and most alloys of these metals. Other examples of ferromagnetic materials include rare earth magnets such as neodymium magnets and samarium-cobalt magnets.

A magnetically susceptible material is a material that is attracted to a magnetic material. Magnetically susceptible materials include magnetic materials and ferromagnetic materials.

In some implementations, the computing device205can be removably coupled to the covering portion120of the folio200via a docking member288. The docking member288can include one or more electronic components through which the folio200can communicate with the computing device205. The docking member288can be configured to be coupled to a portion (e.g., a port) of the computing device205. The docking member288may include a circuit that is configured to communicate data, power, and/or so forth between the folio200and the computing device205. In some implementations, the folio200can communicate a mode to the computing device205via the docking member288. The mode can be communicated via, for example, a mode signal. For example, the mode signal can represent an open mode, a closed mode, a tablet mode, a laptop mode, and so forth. In some implementations, the mode signal can be produced by a processor disposed inside the base portion110and/or the computing device205. In some implementations, the docking member288may transmit data representing, for example, keystrokes received via the input device(s)131.

In some implementations, the docketing member288may include a protective layer292. The protective layer292may protect the docketing member288when the computing device (not shown) is coupled to the docketing member288. In some implementations, the protective layer292can be made from an elastomeric material, such as, for example, silicon rubber.

Example embodiments disclose a method of using the exemplary folios and systems described herein. The method can include rotating the covering portion about a flexible hinge portion in a first direction away from the base portion to an open configuration such that a portion of a first magnetic element is attached to a portion of a second magnetic element, the flexible hinge portion including the first magnetic element and the second magnetic element, and rotating the covering portion in about the flexible hinge portion in a second direction, opposite the first direction, towards the base portion to a closed configuration such that the portion of the first magnetic element is separated from the portion of the second magnetic element.

In some implementations, the method may include the first magnetic element and the second magnetic element can be at least partially attached in the flexible hinge portion. The first magnetic element and the second magnetic element can be rigid as compared to the flexible hinge portion to which the first magnetic element and the second magnetic element are attached in the flexible hinge portion.

In some implementations, the method may include attaching at least one the first magnetic element or the second magnetic element to at least one of a first fabric layer or a second fabric layer. In some implementations, the first magnetic element and the second magnetic element may be disposed between the first fabric layer and the second fabric layer

The computer system (e.g., computing device) may be configured to wirelessly communicate with a network server over a network via a communication link established with the network server using any known wireless communications technologies and protocols including radio frequency (RF), microwave frequency (MWF), and/or infrared frequency (IRF) wireless communications technologies and protocols adapted for communication over the network.

In accordance with aspects of the disclosure, implementations of various techniques described herein may be implemented in digital electronic circuitry, or in computer hardware, firmware, software, or in combinations of them.
