To operate my new SMART PHONE a user must extract both extension screens 92 of FIG. 24 from storage behind display screen middle prefabrication 8 of FIG. 21 where in the extension screens 92 are attached by their respective top and bottom flexible metallic arms 96 of FIG. 20 inside top and bottom slide track chambers 106 of FIG. 19. Both extension screens 92 are extracted when a user grasps either screens' 92 respective circular fingertip grip 10 of FIG. 1 and pulls outwards where upon extension screens 92 of FIG. 24 appear at either sides of middle display screen 90.
Upon extension screens 92 consolidation with display screen 90 of FIG. 23, extracted extension screens 92 which are fastened unto embedded copper power track connectors 78 of FIG. 9 by way of extension screens 92 inter locking slots 94 of FIG. 19, are instantly powered with display screen 90 where upon L/R motion sensors 16 of FIG. 2 automatically integrate extension screens 92 operational functions with those of middle display screen 90 of FIG. 23, while operational functions between display screen 90 and top 6/bottom cap 12 prefabrications of FIG. 2 comes by way of top/bottom female ribbon band connectors 66 respectively of FIGS. 4 and 4A intercourse with top/bottom male ribbon band connectors 38 of FIG. 2.
Both extension screens 92 upon full extraction from storage of FIG. 21 by way of their respective interlock cavities 100 entrapment with locking mechanism snags 108 of FIG. 14 and either screens' 92 respective inter locking slots 94 of FIG. 19 attachment with inter lock ridges 32, locks into stationary positions of FIG. 19 as shown, where upon neither screen 92 can be unlocked for retraction back to storage except by sight upwards lifting on either screens' 92 rear surface as directional arrows of FIG. 19 depicts. Once locking tension is released by upwards lifting both extension screens 92 slides easily from interlock ridges 32 of FIG. 19 for retraction back to storage of FIG. 21 where neither screen 92 can be totally extracted from respective assemblage inside slide track chambers' 106 two-fold storage compartments 110 as extension screens' 92 impressed locking grooves 98 of FIGS. 10 and 11 are designed for such prevention.
When middle display screen 90 of FIG. 23 is joined with extracted extension screens 92 of FIG. 24 at either sides, middle display screen 90 dimensions of 2 6/16 by 41⁄2 inches increase to 71⁄8 by 43⁄8 inches where upon extension screen SMART PHONE, equipped to operate off today's relevant SMART PHONE software, overall appearance of FIG. 1 transform into that of FIG. 24 with a conveniently located volume control bar 52 on rear side of top cap 6 prefabrication.
Alternative Embodiments
Alternatively, instead of an extension screen slide track chambers concept where by additional viewing screens can be joined at either side of middle display screen upon extraction from two-fold passageway/storage compartments of mounted slide track chambers, extension screens can also be consolidated with middle display screen by way of snap, latch, or hook attachment, and any other relevant means where in extension screens can be an ideal feature at either sides, tops, or bottoms of any SMART PHONE and conventional cell phone alike display screens.
Having fully explained my invention, I claim the concepts of a SMART PHONE slide track chamber system in which extension screens by way of circular fingertip grips can be extracted from two-fold passageway/storage compartments for effects of a much larger viewing screen upon extension screens consolidation at either sides of middle display screen, I further claim a three-dimensional extension screen SMART PHONE multi-task concept, where by SMART PHONE and conventional cell phone users alike can simultaneously multi-task in select internet activity on three separate viewing screens as results of a prefabricated SMART PHONE with featured individual extension screens.
2. Operation of the Preferred Embodiment
To operate the invention's dual extension screen, a user must extract extension screens 92 of FIG. 24 from storage behind display screen middle section prefabrication 8 of FIG. 21, wherein extension screens 92 are attached by their respective top/bottom flexible metallic arms 96 of FIG. 20 to interior of top and bottom slide track cambers 106 of FIG. 19. Both extension screens 92 are extracted when a user grabs either screen's respective circular fingertip grip 10 of FIG. 1 and pull outwards, whereupon extension screens 92 of FIG. 24 appear at either side of the main display screen 90.
Both extension screens 92 upon extracted consolidation with main display screen 90 of FIG. 23 are instantly empowered with main display screen 90 as extracted extension screens 92 are fastened onto embedded copper powertrack connectors 78 if FIG. 9 against extension screens 92 copper lined interlocking slots 94 of FIG. 19, whereupon left and right hand side motion sensors 16 of FIG. 2 automatically integrate extension screens operational functions with those of main display screen 90 of FIG. 23, while operational functions between main display screen 90 and top cap/bottom cap sectional prefabrications 6 and 12 respectively of FIG. 2 comes through top and bottom female ribbon band connectors 66 of FIGS. 4A and 4B attachment with top and bottom male ribbon band connectors 38 of FIG. 2.
As shown in FIG. 19, both extension screens 92 upon full extraction locks into stationary positions by way of each respective interlock cavities 100 of FIGS. 10 and 11 entrapment against locking mechanism snags 108 of FIG. 14 and interlocking slots 94 of FIG. 19 attachment to interlock ridges 32. Once locked into stationary positions neither extension screen 92 can be unlocked for retraction back to storage except by slight upwards lifting on either screens 92 rear surface as directional arrows of FIG. 19 depict. Neither extension screen 92 can never be intentionally or over extracted from its position of assemblage as impressed locking grooves 98 of FIGS. 10 and 11 are designed as safeguard for such prevention.
Main display screen 92 of FIG. 23 when consolidated with extracted extension screens 92 of FIG. 24, increase in overall dimensions of 23⁄8 by 41⁄2 inches to 71⁄8 by 43⁄8 inches with a conveniently located volume control bar 52 on rear side of top cap sectional prefabrication 6.
The foregoing descriptions of specific embodiments of the present invention are presented for purposes of illustration and description. They are not intended to be exhaustive nor to limit the invention to precise forms disclosed and, obviously, many modifications and variations are possible in light of the above teaching. By way of example, and not as a limitation, the extension screens can be attached to the immediate sides of main display screen by way of hook or latch attachment; the four manual control buttons affixed to the bottom cap sectional prefabrication can be integrated into the tough screen operational functions; the slide tracking chamber system in which the extension screens are retractable can be easily adapted for electrical operational function; and extension screens can be affixed for vertical extraction/retraction fixture at the top and bottom of the devices, as opposed to the present design of horizontal. The embodiments are chosen and described in order to best explain principles of the invention and its practical application, to thereby enable others skilled in the art to best utilize the invention and its various embodiments with various modifications as are suited to the particular use contemplated. It is intended that a scope of the invention be defined broadly by the Drawings and Specification appended hereto and to their equivalents. Therefore, the scope of the invention is in no way to be limited only by any adverse inference under the rulings of Warner-Jenkinson Company, v. Hilton Davis Chemical, 520 US 17 (1997) or Festo Corp. v. Shoketsu Kinzoku Kogyo Kabushiki Co., 535 U.S. 722 (2002), or other similar caselaw or subsequent precedent should not be made if any future claims are added or amended subsequent to this Patent Application.
