Stand and drawing-easel attached to a keyboard to use with mobile electronic devices

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'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.

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'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.

The opening for stylus or pen storage is shown in FIGS. 20A and 20B. Open space 50 defined by combination of functional cross-sections 38, 40 and 46 can be used to store a pen or stylus 14. The pen-slot 60 secures a pen or stylus 14 as shown in FIG. 21. The pen slot 60 also secures a sliding stylus 14 by a pen-clip 58. Pen-clip access use for pen eject is shown in FIG. 22. A pen can be ejected by pushing on edge of a pen-clip 58. The pen-tip access for pen eject shown in FIG. 23, can be ejected by pushing on pen-tip 62 through a slot 60.

Now referring to FIGS. 24A-D a symmetrical extension wedge fitting in male-female is shown. A sliding-rail on stand core for ‘extended-position’ of extension wedge 68 and sliding-rail on stand core for ‘storage-position’ of extension wedge 66 have the same cross-section. A sling-rail on extension wedge 67 has a male-female relationship with geometry of the sliding-rails on the stand core 66 and 68. The extension wedge 12 has a symmetrical design along its two axes' centers so there is no possibility inserting the extension wedge on the slide-on rails 66 and 68 in a wrong orientation.

An alternative quick-access and storage of the pen stylus is shown in FIG. 25. The sliding-rail for ‘extended-position’ 68 can also be used rail in the pen-clip 58 for alternative quick-access and storage of the sliding-stylus 14.

Smartphone docking is shown in FIG. 26 is accomplished by two or more cavities 70 and 64 that make it possible to place a smartphone 20 of various sizes and thicknesses in two different “writing with keyboard” angles. Smartphone docking on sitting-use angle is shown in FIGS. 27A-C where a smartphone 20 can be placed between 72 upper cut of cavity 70, and a lower cut 74 of cavity 70, and an upper edge 42 of 40 for sitting-use angle.

A smartphone 20 can be placed between the lower cut 74 of cavity 70, and the lower cut 76 of cavity 64, and the upper edge 42 of 40 for a laying-use angle as shown in FIGS. 28A-C.

A range of various thicknesses of a smartphones can be accommodated and/or the extra thickness provided by smartphone-skin 26. Such change in thickness will translate is a slight change in angle of use from the nominal sitting-use angle a shown in FIGS. 29A-B.

A range of various thicknesses of a smartphones can be accommodated, including the extra thickness provided by smartphone-skin 26. Such change in thickness will translate is a slight change in angle of use from the nominal laying-use angle. Rear of thicker devices can fit in a central cavity of stand core 64 as shown in FIG. 30.

Mobile electronic devices larger than smartphones, such as a 5″ plus screen mobile electronic device 80 can also be placed on portrait and/or landscape orientation within the width of the central cavities 70 and 64 as shown in FIG. 31.

7″-8″ screen mobile electronic device 82 thicker than the width of the nesting areas 36 and 38 of the stand core can also be placed on portrait and/or landscape orientation within the width of the central cavities 70 and 64 as shown in FIG. 32.

An optional anti-glare sheet 32 can be sandwiched between the front-glass of slate-devices 18 or smartphones 20 and its matching surface of the nesting cross-sections 38 and 40 as shown in FIG. 33.

A custom-cut privacy sheet for mobile electronic device in landscape orientation 30 covers the active screen area 90 and overextends for the gripping area in nesting areas 38 and 40 where such sheets are held in place. Other elements around the bezel, such as front facing cameras, light sensors or microphones and not occluded by the film as shown in FIG. 34.

A custom-cut privacy sheet for mobile electronic device in portrait orientation 30 covers the active screen area 90 and overextends for the gripping area in nesting areas 38 and 40 where such sheets are held in place. Other elements around the bezel, such as front facing cameras, light sensors or microphones and not occluded by the film as shown in FIG. 35.

Extended-position 86 with slate-device 18 in “drawing easel position” 40 allows extension wedge 12 to be used as a palm-rest during touch interaction as shown in FIG. 36.

A slate-device 18 in a storage-position 84 and “drawing easel position” allows hands to be free from holding slate-device and makes possible two-handed input on the screen as shown in FIG. 37.

A slate-device 18 in an extended-position 86 and “drawing easel position” allows hands to be free from holding slate-device and makes possible two-handed input on the screen as shown in FIG. 38.

A slate-cover 22 such as the APPLE SMARTCOVER for slate-device 18 can be left folded outside of nesting area for “writing with keyboard position” 38 as shown in FIG. 39. An unfolded cover outside of “writing with keyboard” nesting area is shown in FIG. 40. A Slate-cover 22 such as the APPLE SMARTCOVER for slate-device 18 can be left unfolded outside of nesting area for “writing with keyboard position” 38.

A slate-cover 22 such as the APPLE SMARTCOVER for slate-device 18 can be fitted within nesting area for “writing with keyboard position” 38. The extra thickness changes the slate-device 18 angle of “writing with keyboard position” as shown in FIG. 41.

A slate-cover 22 such as the APPLE SMARTCOVER for slate-device 18 can be left folded outside of nesting area for “drawing easel position” 40 as shown in FIG. 42.

A slate-cover 22 such as the APPLE SMARTCOVER for slate-device 18 can be left unfolded outside of nesting area for “drawing easel position” 40 as shown in FIG. 43.

A slate-cover 22 such as the APPLE SMARTCOVER for slate-device 18 can be fitted within nesting area for “drawing easel position” 40. The extra thickness changes the slate-device 18 angle of “writing with keyboard position” as shown in FIG. 44.

A shield created by locally over-extending the length of stand core around 100 power-button of stand-alone keyboard prevents accidental button actuation by nearby objects as shown in FIG. 45.

A softened edge 100 in 10 stand core for accommodating slide installation of stand-alone-keyboard 16 to accommodate protruding parts 102 after attaching the stand-alone keyboard 16 to the stand core 10 as shown in FIGS. 46A-C.

A battery-door 106 of stand-alone keyboard is fully accessible without disengaging 16 stand-alone keyboard and stand core to replace 108 batteries for stand-alone keyboard as shown in FIG. 47.

Now referring to FIG. 48, when a stand-alone keyboard 16 is paired to slate-device 18, the on-screen keyboard 118 does not activate by default for text input. Pressing the on-screen keyboard key 116 makes the on-screen keyboard 118 active without having to un-pair the stand-alone keyboard 116. The stand-alone keyboard's width 112 is greater than slate-device's width 110. This makes the on-screen keyboard key 116 more accessible.

The width difference 11 between stale-device and keyboard makes volume control keys 120, 122, 124 more accessible as shown in FIG. 49

Referring to FIGS. 50-53, a side-by-side nesting of a slate-device 18 and a smartphone 20 is possible in any combination of landscape/portrait mode in either “writing with keyboard position” 38 and/or “drawing easel position” 40. A smartphone 20 can be nested side-by-side next to a slate-device 18 while overhanging from “drawing easel position” 40 cavity to make room for 126 charge/sync cable. The width of extension wedge 128 matches the width of stand-alone keyboard 112 to provide maximum width of contact when used on extended-position 86 resting on a person's lap.

A cut-out 130 on the extension wedge creates a handle that allows a user to carry the extension wedge 12, stand core 10, and the stand-alone keyboard 16 assembled together when moving around. The extension wedge 12 can be easily pulled with 1 or 2 fingers in the cut-out of the extension wedge 130 to slide out from a storage-position 84. The spaced apart walls 132 provide extra gripping surface to facilitate pulling as shown in FIGS. 54A-B.

The localized thicker cross-section at converging end of 12 extension wedge creates an elongated foot or line of contact to the flat ground-plane 134 for the product when the extension wedge 12 is in either in a storage-position 84 or an extended-position 86. This foot expands the stability provided by non-slip coating/padding 50 in stand core 10 as shown in FIG. 55.

The overhang 156 on the cut-out handle on the extension wedge can be used to hang the extension wedge 12, stand core 10, and stand-alone keyboard 16 on a wall 139 or other vertical/inclined surface using a wall-mounted screw 138. A cut-out on extension wedge can be used to hang the extension wedge 12, stand core 10, and stand-alone keyboard 16 on a wall or other vertical/inclined surface using custom hooks 140 or a generic drawer pull or hook 142 as shown in FIGS. 56-57.

UI elements of the stand-alone keyboard 16 can be accessed for actuation or visibility though localized cavities of the stand core 10 that act as see-through windows or holes 146 as shown in FIG. 58. Paring an on-off light 146 on stand-alone keyboard is one example of such UI elements.
