Abstract:
A stand attached to a physical keyboard that holds devices with slate form-factor such as tablets, smartphones, media players and e-book readers. The keyboard-stand combination can hold devices in multiple angles optimal for reading, web-browsing, typing and drawing. The footprint of the keyboard-stand combination is expandable. A minimal ‘storage-position’ provides sufficient stability to be used on a table-top. The non-skid base surface of the stand prevents sliding when actuating mobile electronic devices with fingers. An ‘extended-position’ gives extra footprint and stability to be used in inclined planes or low-friction surfaces also preventing toppling. Optionally the stand can also hold a sliding-stylus for use with such mobile electronic device. Such stylus can be place in a storage position optimized for transport, or in an easy-to-reach inkwell.

     TECHNICAL FIELD OF THE INVENTION 
     The present invention relates generally to external stands for mobile electronic devices. More specifically, the present invention relates to a stand and drawing-easel attached to a keyboard to use with slate or other equivalent mobile electronic devices. 
     BACKGROUND OF THE INVENTION 
     Devices with a slate form factor such as tables, smartphones, media players and e-book readers are hard to hold for long periods of time. External stands can alleviate this problem in many situations. 
     Touch-input and pen-input methods are limited ergonomically when used for extended periods of time. External physical keyboards alleviate this problem for text entry. Easels or stands that hold the tablet can prevent the fatigue of constantly holding the tablet with one hand while pushing against it with the other hand for input directly with fingers or with a stylus. 
     Physically attaching accessories to mobile electronic devices, such as carrying cases with integrated stands, cases with integrated keyboards and/or cases with integrated pen-holders add weight, thickness and complexity to such devices and undermine their mobility virtues. Most of these accessories provide extra functionality but some have minimum stability when using them in places other than on a table-top. They also don&#39;t have very good grip to be placed on an inclined and/or uneven surface such as on a lap while sitting. 
     Most accessories require extra hardware components such as hinges and multiple moving parts to achieve multiple screen angles of the tablet. These accessories also add substantial complexity, size, weight, and possible failure points. 
     DEFINITIONS 
     “Slate” devices, which resemble writing slates, are tablet computers without a dedicated keyboard. For text input, users rely on handwriting recognition via an active digitizer, touching an on-screen keyboard using fingertips or a stylus, or using an external keyboard that can usually be attached via a wireless or USB connection. 
     “Slate” devices typically incorporate small 8.4-14.1 inches/21-36 centimeter LCD screens and have been popular in vertical markets such as health care, education, hospitality, aviation pilot documentation and maps, and field work. Applications for field work often require a tablet computer that has rugged specifications that ensure long life by resisting heat, humidity, and drop/vibration damage. This added focus on mobility and/or ruggedness often leads to elimination of moving parts that could hinder these qualities. 
     “Mobile electronic device” is a general term defined as including an encompassing any mobile electronic machine or computer such as, but not limited to a slate device, tablets, smartphones, media players, and e-book reader, computers, smartphones, IPADs, IPHONEs, and thin laptop. A mobile electronic device is any device with a computer processor and display screen. It may have a touch screen, but that is not required. 
     SUMMARY OF THE INVENTION 
     The present invention relates to a stand attached to a physical keyboard that holds devices with slate form-factor such as tables, smartphones, media players and e-book readers. The keyboard-stand combination can hold devices in multiple angles optimal for reading, web-browsing, typing and drawing. The footprint of the keyboard-stand combination is expandable. 
     A minimal ‘storage-position’ provides sufficient stability to be used on a table-top. The non-skid base surface of the stand prevents sliding when actuating mobile electronic devices with fingers. An ‘extended-position’ gives extra footprint and stability to be used in inclined planes or low-friction surfaces also preventing toppling. Optionally the stand can also hold a sliding-stylus for use with such mobile electronic device. Such stylus can be place in a storage position optimized for transport, or in an easy-to-reach inkwell.

     DETAILED DESCRIPTION OF THE INVENTION 
     In the following are detailed descriptions of the invention of exemplary embodiments. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, but other embodiments may be utilized and logical, mechanical, electrical, and other changes may be made without departing from the scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims. 
     In the following description, numerous specific details are set forth to provide a thorough understanding of the invention. However, it is understood that the invention may be practiced without these specific details. In other instances, well-known structures and techniques known to one of ordinary skill in the art have not been shown in detail in order not to obscure the invention. 
     Referring now to the invention in more detail, the keyboard stand, components, mobile electronic devices, and accessories are show in the figures.  FIG. 1  illustrates an exploded view of one embodiment of the present invention. In this embodiment, the keyboard stand is made out of three parts: a stand-alone keyboard  16 , a stand core  10 , an extension wedge  12 , and a keyboard shield  158 . Also unique to this design are the optional accessories such as a privacy-shield-portrait  30 , privacy-shield-landscape  28 , and anti-glare-shield  32 . 
     This keyboard stand design works with a stand-alone keyboard  16 , and an existing sliding-stylus  14 . It can accommodate a smartphone  20  with or without a smartphone-skin  26  or an slate-device  18  with or without a slate-skin  24  and/or with or without a slate-cover  22 . 
       FIG. 2  shows the coupling stand-alone keyboard with stand core  10  of the keyboard stand is attached to stand-alone keyboard  16  by sliding it into a nesting area  36 . 
     Referring to  FIG. 3 , in a storage-position, the extension wedge  12  fits under the stand-alone keyboard  16  by sliding into a sliding-rail  66  for a ‘storage-position’ of the stand core. Referring to  FIG. 4 -, in an extended-position the extension wedge  12  slides into a sliding-rail  68  for an ‘extended-position’ of the stand core which has provides extra support/stability needed for use on inclined or uneven areas. 
       FIG. 5  illustrates writing in the keyboard position, with the extension wedge in storage-position.  FIG. 6  shows the nesting area for writing with the keyboard. The upper edge of the nesting section  40  for the “drawing easel position” provides extended support for tablets when used in a “writing with keyboard position”. 
     The nesting area for the drawing easel position is shown in  FIG. 7 . The chamfer next to the upper edge of nesting section for “writing with keyboard position”  38  provides extended support for tablets when used in “drawing easel position”. 
     The rectangular generic profile of the nesting cross-sections of  FIG. 8  shows various profiles and protruding elements on tablets which can be accommodated by the rectangular generic profile for the nesting section for “writing with keyboard position”  38  and nesting cross-section for tablets  40 . Support for Writing with keyboard position, extension wedge  12  in storage-position is shown in  FIG. 9  where the length  48  of the base of stand core  46  extends behind the nesting section for “writing with keyboard position”  38  with the nesting section for “drawing easel position”40 to provide enough stability of tablets when using it in “writing with keyboard position” on a tabletop as shown in  FIG. 9 . A non-slip coating/padding  46  on the base of the stand-core  10  provides maximum grip in all surfaces, including a person&#39;s lap or an inclined work surface. 
       FIG. 10  illustrates writing with an extension-wedge  12  in extended-position with respect to the keyboard  16  position.  FIG. 11  illustrates the keyboard stand and typing in an extended position. 
       FIG. 12  illustrates drawing in the easel position, wherein the extension-wedge  12  is in a storage-position.  FIG. 13  illustrates drawing in the easel position on a tabletop.  FIG. 14  illustrates the standing angle for use. 
       FIG. 15  illustrates drawing in the easel position, wherein the extension-wedge  12  is in an extended-position.  FIG. 16  illustrates drawing in the easel position, wherein the extension-wedge  12  is in an extended-position and uses a spacer  10 . 
     As shown in  FIGS. 17, 18A, and 18B , thickness variation can be accommodated. Slates with small thickness variation or with a slate-skin  24  can also be accommodated by the extra room provided by large blended bridge  52  and slightly changing the nested angle  45 . 
     The cross-linked structure x-section is illustrated in  FIG. 19 . The combination of all functional cross-sections  36 ,  38 ,  40  and  46  of the stand core  10  provide a structural frame that prevents the stand core from bending when user presses on screen of slate-device  18  or smartphone  20  during touch input.
