Examples of the disclosure provide a cover for a computing device. The cover is articulated to an edge of the computing device. In one example, the cover includes at least three hinges disposed substantially parallel to the edge of the computing device, the three hinges comprising g a first hinge, a second hinge and a third hinge. Further, the cover comprises at least a first cover section, a second cover section and a third cover section. The first cover section and the second cover section are connected by a first hinge. The second cover and the third cover section are connected by a second hinge. The cover has a connector connected to the first cover section by the third hinge. The connector can be connected to the computing device so as to attach the cover to the computing device. The first cover section, the second cover section, the third cover section, and the three hinges are attached together such that the cover forms a contour to accommodate an object located on the back side of the computing device. Further, the cover becomes substantially flat and parallel to the back side of the computing device when the object is absent.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
A tablet is a small footprint computing device characterized by a touch sensitive screen that often occupies all, or a significant portion of the front of the tablet. The touch sensitive screen receives input from a user and displays output to the user. The user provides input by touching the screen with, for example, a finger or a stylus. Many users use the stylus as a pen for taking electronic hand-written notes or making sketches using digital ink. While some tablets provide an embedded compartment or tether for retaining the stylus, the compartment or tether is designed only for the specific stylus type supplied with the tablet, and is not compatible with different kinds or types of styluses (or other input devices). In systems without the compartment or tether, the stylus is typically carried separately. This often results in a lost or misplaced stylus.
In some systems, the stylus has a clip to affix the stylus to the tablet or to a cover on the tablet. The cover protects the touch sensitive screen from damage. Existing covers are available in many designs, including rigid designs that act similar to a hardback book cover, and foldable designs that convert into a stand to support the tablet at a viewing angle. However, these covers fail to provide secure, internal storage for different types of styluses or other input devices.
Referring to the figures, examples of the disclosure describe a cover for a tablet, or other device with a touch screen, that provides a secure space for conveniently stowing a stylus, pen, or other object on the tablet or cover while also providing protection to the touch screen of the tablet when the tablet is not in use. The cover is attached to the tablet and may swivel around the edge of the tablet, in some examples. Further, the cover may be positioned below, or under, the back side of the tablet as shown in
Aspects of the disclosure provide a cover having flexible, rigid, partially flexible, and/or partially rigid structural material with a clasp, such as schematically shown in
Aspects of the disclosure provide protection to the touch screen and to buttons on the side of the touch screen while at the same time providing stowage for any kind of stylus, pen, or other object for use with the tablet. The cover, when folded over the touch screen, provides protection against scratches, dirt, dust, lotion, oil, liquid, and the like. Further, the cover provides protection against falls, abrasive force, and vibrations encountered at the touch screen side. In some examples, the cover, when folded over the touch screen, generally maintains a small gap between the surface of the cover and the surface of the touch screen. The flexible part of the cover is resilient and provides a degree of damping to any vibrations encountered. Further, when folded over the back side of the tablet, the cover provides protection to a rear camera and any other devices that are on the back side of the tablet. Further, the cover provides a handy and convenient method of storing the stylus on the tablet or cover itself without encumbering the user in the usage of the tablet.
Additionally, the cover provides a user-friendly means for storing the stylus or other objects with the tablet. Aspects of the disclosure provide a convenient means for stowing articles of various sizes and shapes, including any size and shape of stylus, pen, BLUETOOTH brand communication device (e.g., headsets, receiver, transmitter), USB storage device, audio split data cable, universal serial bus (USB) to micro USB adapter, and/or other accessory. The cover may also store more than one object with the cover. The cover, once mated with the tablet, may be wrapped around the back of the tablet and may store the object because the flexible hinges of the cover are wrapped around the object, thus securing the object. The cover, while providing a means for storing the object or other accessory, may be configured to take a position on the back side of the tablet substantially fiat and parallel to the back side.

In one example, the segments 302 include the first cover section, the second cover section and the third cover section as described herein. For example, the first cover section and the second cover section have a first width, and the third cover section may have a second width. Alternatively, the first cover section may have the first width, the second cover section may have the second width, and the third cover section may have a third width. In some examples, the first width, the second width, and the third width each may have a different value. In some other examples, any two of the first width, the second width, and the third width may have the same value. For example, the first width and the second width may each be less than two-thirds of the third width.
In one example, the value of the first width may be less than the value of the second width. For example, the first width may be less than two-thirds less of the second width. In another example, the second cover section may have the third width whose value may he less than the value of the first width. Accordingly, in different examples, the first cover section, the second cover section, and the third cover section may have any combination of the first width, the second width, and the third width. Further, each of the first width, the second width, and the third width may have any value relative to another. In some examples, any one, two, or all of the first cover section, the second cover section and the third cover section may have a fourth width whose value may be greater than, equal to, or less than each of the values of the first width, the second width, and the third width. For example, the fourth width is two-thirds greater than each of the first width, the second width, and the third width.
In some examples, the hinges 304 include the first hinge, the second hinge, and the third hinge as described herein. In an example, the first hinge and the second hinge have the third width whose value may be less than the value of the first width.
In one example, the cover may have a fourth cover section and a fourth hinge (not shown in FIG. In such an example, the fourth cover section may he connected to the third cover section by the fourth hinge. In this example, the fourth cover section may have the second width. The first, the second, and the third cover sections may have the first width, while the value of the first width is different from the value of the second width. For example, the first width may be less than two-thirds of the second width.
The hinges 304 provide articulation between the segments 302 thus imparting the cover 402 with an ability to conform to the contours of the stylus 104 in the stored position on the back side of the tablet 404 while enabling the user to hold and use the tablet 404 without removing the cover 402 or repositioning the stylus 104. Different shapes and sizes of styluses 104 may be stored on the tablet 404 using the cover 402. In some examples, the cover 402 is so constructed that it may store more than one object. For example, there may be two sets of the hinges 304 such that two separate objects may be secured to the back side of the tablet 404 by the cover 402.
When the tablet 404 is not in use, the cover 402 may be rotated around an edge of the tablet 404 in the direction of the touch screen 220 and positioned above the touch screen 220 so that the cover 402 covers the touch screen 220 with a pre-determined gap between the touch screen 220 and the cover 402 as shown, for example, in
In some examples, at least one of the segments 302 may have a magnet 802 embedded or otherwise affixed to it. For example, the tablet 404 may have a Hall effect sensor in the front side 102, while the cover 402 has a magnet 802. When the cover 402 is folded over the touch screen 220, the magnet 802 in the cover 402 may interact with the Hall effect sensor and signal the tablet 404 to transition to sleep mode. A predetermined gap (e.g., two millimeters) between the tablet 404 and the cover 402 provides adequate protection to the touch screen 220 while ensuring that the magnetic field of magnet 802 in the cover 402 is close enough to trigger the Hall effect sensor. Additionally, the gap performs a shock-absorbing function such that shocks not exceeding a threshold value cause the cover 402 to flex about the hinges 304 to absorb the shocks without damage.
The cover 402 may be wrapped around the back side of the tablet 404 even when there is no stylus 104 or any other object stored on the tablet 404 as shown, for example, in FIG, 6. In this position at least one of the hinges 304 (e.g., hinge 1 as shown in
The clasp 306 enables releasable coupling between the tablet 404 and the cover 402. The clasp 306 is attached with the cover receptacle 204 by pressing the clasp 306 into the cover receptacle 204 such that the clasp 306 snaps in, in some examples. Alternatively, the clasp 306 may he magnetically attached to the cover receptacle 204. In such examples, both the clasp 306 and the cover receptacle 204 may contain magnetic components such that when brought close to each other, the clasp 306 snaps into the cover receptacle 204 in a pre-determined alignment position. Any other mechanism for attaching the clasp 306 to the cover receptacle 204 may be used including, for example, buttons, snaps, zippers, and/or hook-and-loop fasteners.
In some examples, one or more electrically conducting wires may run along at least a portion of the length of the cover 402. In such examples, the coupling between the clasp 306 and the cover receptacle 204 is both mechanical and electrical. For example, the cover 402 may have intelligent electrical circuitry and sensors to sense the direction of movement and the current configuration and/or orientation of the cover 402. For example, the intelligent circuitry and the sensors determine whether the cover 402 is being moved from beneath the back side (e.g., open position) towards the touch screen 220 (e.g., closed position) or vice versa. Alternatively or in addition, the circuitry and sensors detertnine the presence or the absence of any object within the cover 402. Information relating to the presence or absence of the object is sent to the tablet 404. The tablet 404 provides electrical signals, through the conducting wires, to make at least some of the hinges 304 rigid when no object is stored within the cover 402 and make at least some of the hinges 304 flexible when an object is stored therein. Electrical coupling between the clasp 306 and the cover receptacle 204 may also provide a channel for transmitting data between the cover 402 and a device, such as a tablet or smartphone, This data may represent sensed touch input on the cover 402 or signals to control and/or power displays, lights (e.g., light emitting diodes), sensors, or other electrical devices in the cover 402 or device.
Further, the intelligent circuitry and the sensors, in conjunction with the tablet 404 and the wires, may control the sequence of articulation of the hinges. While in some examples all the hinges 304 may bend to accommodate the object, the hinges 304 may bend in sequence in other examples. For example, hinge 1 (e.g., as shown in FIGS. 6 and 7) bends first, hinge 2 subsequently bends (during or after hinge 1 has completed bending) if the curvature being provided by hinge I is not adequate to accommodate the object, hinge 3 subsequently bends, and so on, The sequence and the extent of bending by each hinge 304 may be controlled by the wires based on the received signals. In general, the tablet 404 may send a signal to the cover 402 to cause the hinges 304 to articulate one at a time, two at a time, simultaneously, sequenced, and the like.
In one example, the intelligent circuitry and the sensors may comprise a microelectromechanical system (MEMS) enabling communicating between the tablet 404 and the cover 402 to alter the conditions of the hinges 304 based on the configuration of the cover 402. The intelligent circuitry and/or the sensors may also implement near-field communication (NEC) to convey the signals. BLUETOOTH brand communication modules may also be employed to implement the intelligent circuitry and/or the sensors in the tablet 404 and/or the cover 402.
Alternatively or in addition, the Hall effect sensor detects a changing magnetic field strength when the cover 402 is being moved from a closed position to an open position and vice versa. Accordingly, the direction of movement and the current position of the cover 402 may be detected. Based on such sensing, the tablet 404 may provide signals to the cover 402 to cause changes in the characteristics of the hinges 304 and the state of the embedded wires to match the current configuration and/or position of the cover 402. Hence, the tablet 404 may cause changes in the flexibility of the hinges 304 and the tension of the wires thus allowing the cover 402 to swivel around the edge of the tablet 404 and form a contour around the stylus (if present). Once positioned correctly, that position may be maintained by again modifying the state of the embedded wires and the flexibility of the hinges 304 to cause rigidity of the hinges 304 in the changed configuration.

The cover 402 may also have a pocket, loop, slot, or other feature, on a side of the cover 402, to hold a pen, paper, portable storage device (e.g., thumb drive), or other objects.
The advantages of the cover 402 depicted in
In some examples, one or more of the segments 302 and/or the hinges 304 are of different shapes and/or sizes. Further, the spacing between the hinges 304 may depend on the size of the object to be accomodated by the cover 402. For example, the spacing between the hinges 304 may be larger to accommodate larger objects, or smaller in other examples to accommodate smaller objects. Further, the quantities and sizes of the segments 302 and the hinges 304 are also a function of the size and/or shape of the object to be accommodated (e.g., cylindrical, rectangular, triangular, etc.). The shape, size, and/or spacing of the segments 302 and the hinges 304 also depend on the characteristics (e.g., shape, size, etc.) of the tablet 404 for which the cover 402 is designed. In some examples, at least two hinges 304 with a spacing therebetween are used. An exemplary spacing for the two-hinge example is 3±0.5 millimeters. In other examples, three hinges 304 are used with a spacing therebetween. An exemplary spacing for the three-hinge example is 7.5±0.5 millimeters.
In some examples, the segments 302 are made of rigid structural material such as glass-reinforced epoxy laminate (GRP) sheets of suitable thickness. In an exemplary example, the thickness of the segments 302 may be 2±0.2 millimeters after fabric is applied to cover the segments 302. Further, the GRP may be fire-retardant conforming to National Electrical Manufacturing Association (NEMA) FR-4 grade, or US Military specification MIL-I-24768/27. In other examples, other reinforcing materials such as paper, canvas, linen may be used, and any suitable thertno-setting resin may be used for construction of sheets to fabricate the segments 302. Various other materials for fabricating the segments 302 to have the desired characteristics (e.g., rigidity, temperature stability, durability, resistance to de-lamination) are also contemplated.
In an exemplary example, the hinges 304 are made of polyethylene terephthalate (PET) film. The thickness of the hinges 304 may range between 0.075-0.125 millimeters, in some examples. At least one example may use hinges having a thickness of 0.125±10% millimeters. In other examples, polyurethane, polycarbonate, or metal films may be used for construction of the hinges 304. Various other materials for fabricating the hinges 304 to have the desired characteristics (e.g., flexibility when out of plane and rigidity when in plane, temperature stability, malleability, ductility, durability) may be used.
In some examples, the segments 302 and the hinges 304 are wrapped with a continuous piece of fabric with adhesive to form the cover 402. In other examples, the cover may be formed by one piece of a continuous fabric without seams functioning essentially as a single hinge. In some examples, the fabric is composed of microfiber made of polyesters, polyamides or similar plastic material.
Further, the cover 402 may be formed with a single piece of continuous flexible film that is stiffened in portions to form the segments 302. In such examples, the unstiffened portions remain flexible to act as the hinges 304, while the stiffened portions act as the segments 302. Aspects of the disclosure are operable with any form or type of stiffener, such as acrylic polymer, latex, polyester, and more.
The hinges 304, while substantially rigid when straight and in plane, are amenable to bending in a near semi-circular shape when subjected to a force normal to the device and applied at the edge of the larger non-flexible segment as if being held in the hand. This force is approximately 10 Newtons while remaining within the elastic deformation range. The thickness, spacing, and the number of hinges 304 may be chosen based on the shape and size of the object to be accommodated, and/or the shape, size and contours of the edge of the tablet 404 alone: which the cover 402 may swivel when being positioned on the back side of the tablet 404 and accommodating objects such as the stylus 104.
At 902, the process of assembly begins, At 904, two or more portions of a flexible film are provided. At 906, a sufficient quantity of portions of a rigid material is provided such that one part of a rigid material may be placed between two parts of the flexible film. At 908, one part of the rigid material is longitudinally placed between two parts of the flexible film such that all the parts are adjoining each other such as illustrated in
