BACKGROUND

Because of their portability and ease of use, consumers are increasingly using tablet computers. However, the portability of the tablet computer also has some disadvantages because it may not have all the functionality of a more robust computing device, such as a laptop. For example, word processing on a touchscreen keyboard can be cumbersome and less efficient. Consumers who desire the word processing functionality of a laptop have the option of attaching a keyboard to their tablet computer. Other consumers want to use their tablet computer for media applications, such as games or videos. Some consumers may not only use their tablet computer for a single purpose, but may also use it for word processing, media applications, and various other uses.

It is therefore desirable to have improved methods and apparatuses for solving some of the problems discussed above while reducing some of the disadvantages noted above.

In the 5A to 5H is a sequence of stages of an arrangement of the protective cover 100 represented according to a particular embodiment of the invention in a closed flap-like arrangement. In 5A is a removed tablet computer 105 shown in the vicinity of the protective cover 100 according to an embodiment of the invention. 5B puts the tablet computer 105 like this one on the protective cover 100 is present, but not yet over the hinge 130 is fixed in a closed arrangement. The 5C to 5E show the tablet computer 105 as on the protective cover 100 is present, with each subsequent figure the tablet computer 105 gradually closer in the direction of the hinge 130 pushed shows. In each case, the hinge closes 130 flush with the protective cover 100 from. 5F put that on the protective cover 100 According to one embodiment of the invention applied tablet computer 105 closer in the direction of the hinge 130 Once pushed the tablet computer 105 close enough to the hinge 130 is located, the hinge jumps from the flush position due to the magnetic attraction to the tablet computer 105 out. For example, one will be inside the bolt 130 arranged magnet (not shown) attracted by a magnet arranged in the tablet computer, whereby the bolt 130 ascends (ie, pivots upward from the flush position). 5G put that on the protective cover 100 According to one embodiment of the invention applied tablet computer 105 pushed even closer in the direction of the hinge. The tablet computer 105 (and the magnet inside) is now so close to the bar 130 in that the latch is fully swung out and in position for docking with the tablet computer and securing the tablet computer 105 in a closed position. 5H put that on the protective cover 100 According to one embodiment of the invention applied tablet computer 105 pushed into a completely closed arrangement, so the hinge 130 on the tablet computer 105 rests against this and the protective cover 100 attached.

5I illustrates an input device 105 that with a protective cover 100 is connected in a closed position according to an embodiment of the invention. The protective cover 100 has a housing 102 on, which is the main body of the protective cover 100 can form. The housing 102 can the groove 120 and the locking mechanism 130 exhibit. The housing 102 can have a front area 111 which may have a plurality of keys (not shown) disposed therein, and a rear portion 112 include the locking mechanism 130 can have. In addition, the housing can 102 a surface 104 exhibit. The locking mechanism 130 can be a top 135 and a bottom 137 exhibit. In some embodiments, the locking mechanism 130 to the rear area 112 of the housing 102 be articulated connected or connected. The input device 105 can be a surface 108 exhibit. The surface 108 For example, it may be any suitable display known to those skilled in the art (eg, a touch screen, LCD screen, etc.).

In some embodiments, the locking mechanism 130 for coupling to the input device 105 (eg surface 108 ) and to attach this to the surface 104 of the housing 102 be educated. In addition, the locking mechanism 130 by means of the hinge coupling for pivoting between a first arrangement 180 and a second arrangement 190 be educated. In some embodiments, the first assembly is a closed position with the top 135 the locking mechanism 130 flush with the surface 104 of the housing 102 is aligned and the bottom 137 the locking mechanism 130 inside the case 102 is recorded so that the locking mechanism 130 does not protrude from the case. The second arrangement 190 may further represent an open position in which the locking mechanism 130 opposite the closed position (eg first arrangement 180 ) is pivoted and out of the housing 102 protrudes. In certain embodiments, the locking mechanism 130 by means of the hinge coupling of the first arrangement 180 in the second arrangement 190 be swung open. As stated above, the locking mechanism 130 a magnet (not shown) operable to couple the locking mechanism 130 to the input device 130 (For example, a tablet computer) is formed. In some embodiments, the locking mechanism may be 130 under the influence of a magnetic field automatically from the first arrangement 180 in the second arrangement 190 to open. The input device 105 For example, it may have a magnet disposed therein, the latch when the magnet is close to that in the latching mechanism 130 located magnet due to the magnetic attraction between the two magnets as in the 5E to 5H shown rises.

In certain embodiments, the in the locking mechanism 130 Magnet (not shown) apply a magnetic force, which is an increase of a holding force of the locking mechanism 130 causes. The holding force may be related to a force required to remove the input device from the locking mechanism 130 is required, for example, if the tablet computer 105 from the protective cover 100 is removed. In some embodiments, the locking magnet (s) may exert a magnetic force in such a magnitude that the retention force of the locking mechanism 130 greater than the weight of the protective cover 100 and input device (eg, tablet cover 105 ) is together. For example, a user may, if a protective cover 100 and a tablet computer 105 are in a collapsed arrangement, wherein the locking mechanism 130 Magnetic to the tablet computer 105 is docked (for example, to another in the tablet computer 105 magnets magnetically coupled), the unit of protective cover 100 and tablet computers 105 with one hand (eg by only holding the tray cover 100 engages) without interfering with the locking mechanism 130 the connection with the (ie the magnetic coupling to the) tablet computer 105 solves. Therefore, a user usually has to overcome the holding force for releasing the connection. In some cases, the retention force of the latch may be present when coupling the input device (eg, the tablet computer 105 ) are reduced to the latch in the open position, wherein the input device is moved relative to the housing beyond a critical angle. In other words, a user moves a tablet computer 105 similar to opening a book from the protective cover 100 away (eg, puts the protective cover 100 the back cover, which rests on a surface, and the tablet computer 105 represents the front cover opening at an angle relative to the back cover). In certain embodiments, the critical angle is usually more than 45 degrees. In further embodiments, the holding force of the locking mechanism 130 by applying a lateral force to the input device (ie, a force perpendicular to that between the latching mechanism 130 and the tablet computer 105 acting magnetic force).

Alternatively, other methods and / or means for improving the holding force of both the locking mechanism 130 as well as the groove 120 be used. For example, instead of magnets, other devices such as hook-and-loop fasteners, retaining pins, wire pins, adhesives, electromagnets, higher coefficient of friction links, sucker, stiff hinges, stiff slots, and other devices may be useful to those skilled in the art having access to this disclosure appear to be used.

The perspective view of 6 provides a protective cover 600 with a locking mechanism 630 according to an embodiment of the invention, for attaching to a tablet computer 105 is trained. The locking mechanism 630 can, as will be described further below, pivot into an open position and laterally toward the rear of the protective cover 600 slide out. The protective cover 600 has an upper area 602 and a lower area 604 on. The upper area has a keyboard 610 , a groove 620 and a locking mechanism 630 on. In a closed arrangement (not shown), the protective cover 600 be designed so that it is firmly in a flap-like arrangement over a tablet computer 105 is mounted to protect it from damage (eg scratches, notches, impact damage, etc.). A latch 630 may be from one (as shown within the upper range 602 in a closed position) to hold, maintain, and secure the flap-like assembly to a portion of the tablet computer 105 (eg via a magnetic coupling, mechanical coupling, etc.) to be attached. In an open position, the groove 620 the tablet computer 105 , around To enable a user to have an optimal viewing angle, in a number of different upright positions.

In some embodiments, the latch is 630 in the top 602 the back of the protective cover 600 integrated and designed so that it as in the 7A to 7E shown from a flush position (flush with the top 602 ) automatically pops up and gets on the tablet computer 105 attached when the edge of the tablet computer 105 in the immediate vicinity of the bar 630 located. The auto-lock features may be implemented using a magnetic device, electromagnetic device, mechanical device, motion detection, proximity sensing, or any other technology that may be considered appropriate to one of ordinary skill in the knowledge of the disclosure. For example, the protective cover 600 work that way within the tablet computer 105 located magnet detects and the bolt 630 for attaching or attaching the tablet computer 105 on the protective cover 100 automatically opens in a flap-like arrangement.

In 7A is a process for attaching a tablet computer 105 on a protective cover 600 represented according to an embodiment of the invention. In 7A the tablet computer approaches 105 the hinge 630 but is not attached to it yet. The hinge 630 remains in the with the protective cover 600 flush position. In 7B is a process for attaching the tablet computer 105 on a protective cover 600 represented according to an embodiment of the invention. In this case, the tablet computer is located 105 close enough to the hinge 630 so the hinge 630 due to its magnetic attraction to the tablet computer 105 jumps out of its flush position. For example, one will be inside the bolt 630 arranged magnet (not shown) of one in the tablet computer 105 magnets magnetically attracted, causing the bolt 630 ascends (ie, pivots upward from the flush position).

In 7C a tablet computer is shown, according to an embodiment of the invention even closer to the hinge 630 is pushed. The tablet computer 105 (and the magnet inside) is close enough to the latch 630 so the latch 630 is fully extended (ie, pivoted into a fully open configuration) and in a position for docking with the tablet computer 105 and for securing it in a flap-like arrangement. In 7D is a tablet computer 105 shown on the protective cover 600 according to one embodiment of the invention is applied. In addition to the complete extension of the bolt 630 in a fully open and pivoted position is the bolt 630 also laterally from the back of the protective cover 600 pushed out, leaving the tablet computer 105 in the folded arrangement with the protective cover 600 can be aligned. In this regard, the protective cover differs 600 from the protective cover 100 , In some embodiments, the protective cover is 100 (from front to back) longer than the tablet computer 105 so the latch 130 as in 4 shown enough room to swing and dock with the tablet computer 105 Has. The protective cover 600 on the other hand it pivots (or folds) and slides out of the back of the protective cover 600 out.

magnets

In 11 are several according to an embodiment of the invention in a protective cover 1100 embedded magnets shown. Magnets may be used to secure a tablet computer in both the closed (ie, flap-like arrangement) and active arrangements (the tablet computer 105 is used in the groove in an upright position) can be used.

The protective cover 1100 can be one or more magnets 1150 have in the space bar one on the protective cover 1100 attached or attached keyboard or embedded around the space bar, wherein the arrangement of the magnets corresponds to that in the tablet computer 105 are arranged so that the protective cover 1100 and the tablet computer 105 can be held in a closed (ie flap-like) arrangement. In 12 is, for example, a spacebar 1200 with magnets arranged therein according to an embodiment of the invention 1250 shown. The magnets can be arranged so that they are in the closed position of those in the tablet computer 105 magnetically attracted to embedded magnets. In some embodiments, the magnets may be magnetically attracted to other magnetic objects. For example, the magnets can 1250 from a metal case or frame in the tablet computer 105 be attracted. Magnets can also be in front of the space bar 1200 arranged and in the housing (ie in the main body of the protective cover 1100 ). In some embodiments, those in the space bar 1200 arranged magnets 1250 cause the space bar 1200 when the protective cover 1100 in a closed position, magnetic to the tablet computer 105 is attracted. In some cases, the magnetic attraction leads to a slight lifting of the space bar, making it the tablet computer 105 touched. This may be advantageous in that the space bar, which usually has no script or graphic image applied thereto by means of screen printing or other printing, can prevent other keys and the characters printed thereon from hindering the tablet 105 touch in the closed position and be removed unintentionally with time.

The protective cover 1100 can in a hinge 1130 embedded magnets 1130 exhibit to a tablet computer 105 as above with reference to the 4 to 8D was described to hold at the back.

In some embodiments, the magnets may be disposed in or around the groove to determine the suitability of the protective cover 1100 to keep a tablet computer in the active position without it sliding off or falling out (ie, preventing upward and lateral movement). In 13 are for example several magnets 1350 shown in the groove 1320 and / or are arranged around the groove. The magnets 1350 can be arranged so that they are magnetically attracted to the active arrangement of magnets in the tablet computer 105 are embedded. In some embodiments, the magnets 1350 attracted by other magnetic objects. For example, the magnets can 1350 from a metal case or frame in the tablet computer 105 be attracted. Even if in 13 a certain number of magnets 1350 shown in and / or around the groove 1320 Any number of magnets may be used. For example, in some embodiments, more or fewer magnets may be used. Besides, the magnets can 1350 have any suitable size, shape and composition. In some cases, magnets can be used 1350 embedded in the groove, on the surface of the groove 1320 arranged, embedded within the housing (ie not as part of the groove 1320 ), but close enough to the tablet computer 105 in an upright position. The magnets 1350 can according to need in each with respect to the groove 1320 suitable arrangement can be arranged.

In certain embodiments, the one or more are in or around the groove 1320 arranged magnets 1350 designed to provide a magnetic force whose function is to increase the holding force of the groove. The holding force may be associated with the strength of a force that needs to be applied to an input device (eg, a tablet computer 105 ) out of the groove 1320 out or remove it, when the input device is arranged in one of the several upright positions. For example, when an input device is inserted into the groove in a forward, upright position, the holding force determines the amount of force that a user must apply to pull the input device out of the groove. In some embodiments, the magnets bring 1350 a magnetic force in a thickness at which the holding force of the groove 1320 greater than the weight of the protective cover 1100 and input device is together. For example, when an input device is inserted into the groove in a forward facing upright arrangement, a user may merely use the tablet computer 105 touch and pick up and thereby the combination of tablet computer 105 and protective cover 1100 Lift, since the holding force of the groove is large enough to hold the common weight of the two. This can be very useful when a user wants to quickly pick up the combination with one hand and move it to another location, without worrying about the tablet computer 105 could fall out of the groove. In some embodiments, the retention force of the groove may be reduced if the input device is displaced laterally out of the one or more upright positions along the groove, or if the input device is moved out of the one or more upright positions by a critical angle. For example, the tablet computer 105 in the groove 1320 in the forward facing arrangement at an angle of 72 degrees (see e.g. 15 ) stand. By moving of the tablet computer 105 towards 90 degrees and beyond, the holding force of the groove can be reduced so much that the tablet computer 105 at the steeper angles easier to remove from the groove. The angular range required to reduce the holding force may change as it is known to those skilled in the art, having this disclosure.

In some embodiments, additional features may be incorporated to securely hold the tablet computer 105 in the as shown in this document for the various embodiments support active and the closed arrangement. For example, in the places where the tablet computer 105 The protective cover in the keyboard assembly touches, friction pads are installed, which prevent the tablet computer 105 slides out of its position. In addition, the groove 1320 Also, be elevated above the top surface to allow for additional lateral retention (eg, mechanical force) of the tablet computer 105 to allow, for. B. by concerns about the tablet computer 105 in a closed arrangement, or a larger surface for application to the tablet computer 105 to create in the active arrangement. The groove may be made of any suitable material. For example, the groove 1320 have a double-injected silicone.
