## Background
FIELD OF THE INVENTION
The present invention relates generally to cradles for holding portable electronics devices, and in particular to docking stations for portable computers and other portable electronics devices having one or more input/output (I/O) communication ports.
BACKGROUND OF THE INVENTION
Docking stations are generally well-known for supporting a portable computer, cellular telephone, portable music player or other portable electronic device. Such docking stations are equipped with an input/output (I/O) connector for interfacing the electronic device to peripheral hardware. To date, I/O connectors of such docking stations are generally dedicated to interfacing a single function, such as keyboard input/output, audio/video output, printer output, or synchronization coupling to name a few.
However, known docking station apparatus are limited by being dedicated to supporting only one of these various I/O connectors for interfacing with a particular portable device.
SUMMARY OF THE INVENTION
The present invention is a universal adapter mount for a cradle structured to support a portable computer, cellular telephone, portable music player or other portable electronic device.
According to one aspect of the invention the universal adapter mount includes an adapter module that is mountable on a docking tray for holding a portable device. A housing is formed with an opening adjacent to one surface thereof that communicates with an internal cavity formed therewithin. The cavity is sized to fit a body of an interface adapter, while the opening is sized to admit a plug portion of the interface adapter therethrough, whereby the adapter plug and contacts are exposed outside the housing. An electrical interface adapter cable from the adapter body exits the internal cavity, for example, through an aperture in the housing. A compression plate is positioned within the housing internal cavity with the interface adapter body with a means for urging the compression plate toward the opening and thereby compressing the adapter body against a lip around the opening and simultaneously urging the plug portion of the interface adapter through the opening.
The adapter housing is optionally molded, for example injection molded, of a plastic or carbon fiber material. For ease of manufacturing, when the adapter housing is molded, the shoulder around the opening may be thicker than optimal for mating the adapter plug with the I/O port of a portable electronic device seated in the docking tray. Therefore, the opening into the internal cavity may be enlarged to accept the portion of the portable device having the I/O port. The housing optionally includes a thin outlet plate seated against the lip of the opening and having an outlet aperture therethrough sized to admit the adapter plug, while interfering with passage of the adapter body. The outlet plate is thin enough to project enough of the adapter plug to reliably interface with the device I/O port, yet strong enough to resist the pressure applied by the compression plate.
The universal adapter mount is coupled to a docking tray with the adapter module positioned adjacent to an interface portion of the tray wherein the portable computer, cellular telephone, portable music player or other portable electronic device will reside, with the plug of the interface adapter positioned to be received into the I/O port of the portable device.
Other aspects of the invention are detailed herein.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
In the Figures, like numerals indicate like elements.
FIG. 1 illustrates a docking station 10 for supporting a portable electronics devices, such as an Apple® iPad, a portable computer, cellular telephone, portable music player or another such portable electronic device intended to be operated with a docking station. Such portable electronics devices have an input/output (I/O) port for communicating signals for driving multiple functions, such as keyboard input/output 1, audio output 2, audio/video output 3, data storage input/output 4, printer output 5, image input/output 6, game control input/output 7, data input/output 8, or synchronization coupling to another device 9, just to name a few. Docking station 10 includes a docking tray 12 structured to receive thereinto the iPad or another portable electronic device, and a universal adapter module 14 for interfacing with the iPad or other portable electronic device through its I/O port. Docking tray 12 includes an tray body 16 having a bearing surface 18 on which the electronics device is to be placed, and a receiver structure 20 positioned adjacent to an edge 22 of bearing surface 18. Bearing surface 18 is positioned between opposing side walls 24 that help position the electronics device in tray 12.
Tray body 16 includes a clamping portion 26 extended from bearing surface 18 substantially opposite from receiver structure 20. Clamping portion 26 is adapted for cooperating with receiver structure 20 for securing the electronics device relative to tray body 16 and bearing surface 18 thereof. Clamping portion 26, for example, is formed of slightly flexible neck 28 that is an extension of tray body 16. Clamping portion 26 has a clip or roller 30 secured adjacent to one end of flexible neck 28 distal of bearing surface 18 for alternately securing the electronics device in docking tray 12 and releasing it therefrom.
Receiver structure 20 is structured to receive the iPad or other portable electronics device. For example, receiver structure 20 is pivotally tiltable relative to tray body 16 between an open state and a clamped state. For example, receiver structure 20 is pivotable by means of one or more pivot pins 32 coupled between receiver structure 20 and tray body 16. Here, docking tray 12 is configured in the open state with receiver structure 20 rotated outwardly from bearing surface 18 of tray body 16 for receiving thereinto the electronics device.
According to one exemplary embodiment, receiver structure 20 is formed as a J-cup having a tilting receiver 34 sized to receive a portion of the electronics device, and may have a front lead-in lip 36 for guiding the electronics device thereinto. J-cup receiver 34 pivots relative to tray body 16 into the open position (FIGS. 1, 2, 3) tilted away from bearing surface 18 of tray body 16 to aid in easy insertion and removal of the electronics device. J-cup receiver 34 also pivots back toward bearing surface 18 into closed position (FIGS. 4, 5) for seating electric device 14 against bearing surface 18 with I/O port positioned for interfacing with the universal adapter module 14. Docking tray 12 may have opposing side lips 38 for helping position the electronics device relative to universal adapter module 14.
J-cup receiver structure 20 optionally includes one or more movable preload levers 40 adjacent to bearing surface 18. For example, each preload lever 40 includes an arm 42 extended from a rear portion 44 of tilting J-cup receiver 34 of receiver structure 20 whereby preload levers 40 are pivotable relative to bearing surface 18 in combination with tilting J-cup receiver 34 by operation of pivot pins between receiver structure 20 and tray body 16. Additionally, each preload levers 40 optionally includes a compression portion 46 adjacent to an end of arm 42 distal from J-cup receiver 34 and raised above level of arm 42 inwardly toward receiver cup front portion 36. Optionally, recesses 48 sized for receiving thereinto preload levers 40 are formed in bearing surface 18 whereby the electronics device is permitted to seat against bearing surface 18 without interference from levers 40.
Optionally, an urging means 52 is coupled between preload levers 40 and tray body 16 for urging preload levers 40 outwardly of bearing surface 18. For example, urging means 52 is a spring or other resilient biasing member coupled between tray body 16 and receiver structure 20. Optionally, urging means 52 is positioned between individual preload levers 40 and tray body 16. According to one embodiment, travel of tilting J-cup receiver 34 of receiver structure 20 outwardly away from bearing surface 18 is limited. For example, a stop 54 on receiver structure 20 is positioned to encounter edge 22 of bearing surface 18 or another portion of tray body 16 for arresting outward travel of receiver structure 20.
FIG. 2 is a side view of docking station 10 that more clearly illustrates J-cup receiver 34 of receiver structure 20 configured in the open position tilted away from bearing surface 18 of tray body 16 to aid in easy insertion and removal of the electronics device.
FIG. 3 shows universal adapter module 14 that is mountable and mounted on docking station 10 for interfacing with the portable electronics device through its I/O port. Universal adapter module 14 includes an interface adapter 62 positioned on docking tray 12. For example, interface adapter 62 is extended through an aperture 64 in an interface portion 66 of J-cup receiver 34 in a position to interface with a mating I/O port of the electronics device when it is installed in docking station 10. Here, a pair of adjusters 68 position interface adapter 62 in aperture 64 and projected outwardly of interface portion 66 of J-cup receiver 34 to couple with I/O port of the electronics device seated in receiver structure 20.
FIG. 4 illustrates docking station 10 having docking tray 12 configured in the clamped state with receiver structure 20 rotated inwardly toward bearing surface 18 of tray body 16 for clamping the electronics device. While docking tray 12 is configured in the open state with receiver structure 20 tilted outwardly of bearing surface 18 of tray body 16, the electronics device is fit into J-cup receiver 34 with its I/O port mated with interface adapter 62. Receiver structure 20 is rotated inwardly toward bearing surface 18 of tray body 16, whereby the electronics device encounters clip or roller 30 at end of neck 28.
Here, neck 28 of tray body 16 is sufficiently flexible to permit the electronics device to pass between receiver structure 20 and clip or roller 30 to become seated against bearing surface 18 of tray body 16. Furthermore, neck 28 is sufficiently resilient to reform over the electronics device, and subsequently to compress the electronics device against interface portion 66 of J-cup receiver 34 and into mating contact with interface adapter 62.
When present, preload levers 40 of J-cup receiver structure 20 press outwardly of bearing surface 18 of tray body 16 for urging the electronics device against clip or roller 30 of neck 28. The electronics device is thereby restrained from moving within J-cup receiver 34 when docking station 10 is jostled or bumped. Such restraint of the electronics device causes its I/O port to remain firmly mated with interface adapter 62 in interface portion 66 of J-cup receiver 34.
FIG. 5 is a side view of docking station 10 that more clearly illustrates J-cup receiver 34 of receiver structure 20 configured in the clamped state with receiver structure 20 rotated inwardly toward bearing surface 18 of tray body 16 for clamping the electronics device.
FIG. 6 is a cross-section view of docking station 10 showing details of universal adapter module 14, wherein interface adapter 62 is projected through aperture 64 in interface portion 66 of J-cup receiver 34. For example, interface adapter 62 is formed of an adapter body 70 and an adapter plug 72 of a type that is adapted for interfacing with the portable electronic device through its I/O port. Interface adapter 62 has an adapter cord or cable 74 operatively coupled to adapter plug 72 and extended from adapter body 70. For example, one or more electrical conductors 74a of cable 74 are electrically coupled to corresponding connector pins 72a of adapter plug 72. Interface adapter 62 is any one of a plurality of possible interface adapters of a type that is configured to interface with a particular portable electronics device, such as an Apple® iPad, a portable computer, cellular telephone, portable music player or another such portable electronics device. Each of the plurality of possible interface adapters 62 is generally dedicated to interfacing a single function, such as keyboard input/output, audio/video output, printer output, or synchronization coupling, or another function. Alternatively, at least one of interface adapters 62 is a universal serial bus (USB) connector according to industry standards for connection, communication and power supply functions.
Adapter module 14 includes a housing 76 molded with an internal cavity 78 and one adapter opening 80 formed in a surface 82 thereof and communicating with internal cavity 78. A plug outlet plate 84 is positioned adjacent to adapter opening 80, for example but not limited to being positioned within internal cavity 78 of housing 76. Alternatively, outlet plate 84 is positioned externally of housing surface 82. Outlet plate 84 may alternatively be embedded in housing surface 82 within adapter opening 80. Outlet plate 84 includes an outlet aperture 86 and sized to pass adapter plug 72 slidingly therethrough without passing adapter body 70. Outlet plate 84 is sufficiently thin at least adjacent to plug outlet aperture 86 to permit a maximum length of adapter plug 72 to project therethrough for reliably interfacing with the electronics device to be placed in tray body 16. Accordingly, outlet plate 84 is preferably formed of a thin section of a substantially rigid metallic material, such as but not limited to steel.
Internal cavity 78 of housing 76 is sized to receive body 70 of interface adapter 62 therewithin with adapter plug 72 projected out of cavity 78 through outlet aperture 86 in outlet plate 84. Internal cavity 78 is further sized to receive a movable compression plate 88 positioned within housing internal cavity 78, with adapter body 70 positioned between compression plate 88 and housing adapter opening 80. Adapter cord or cable 74 of interface adapter 62 exits housing 76 through a cable aperture 90 formed through a wall 92 of housing 76.
Pair of adjusters 68 operate as means for urging movable compression plate 88 toward adapter opening 80. Pair of adjusters 68 is provided for compressing adapter body 70 between compression plate 88 and plug outlet plate 84, whereby adapter plug 72 is forcibly projected outwardly of housing cavity 78 through plug outlet aperture 86 in outlet plate 84. For example, adjusters 68 are threaded members or screws each operably coupled between outlet plate 84 and compression plate 88. Threaded adjusters 68 are operable in a compression mode for urging compression plate 88 toward (arrow 94) plug outlet plate 84 and compressing adapter body 70 therebetween, threaded adjusters 68 thereby forcibly project adapter plug 72 outwardly of housing cavity 78 through plug outlet aperture 86 in outlet plate 84. Threaded adjusters 68 are also operable in an expansion mode for moving compression plate 88 away from (arrow 96) adapter opening 80. Thus operated in expansion mode, threaded adjusters 68 permit or urge compression plate 88 away from housing adapter opening 80, whereby adapter plug 72 of interface adapter 62 is withdrawn from plug outlet aperture 86 and adapter body 70 is disengaged from outlet plate 84. An access plate 98 permits access to housing internal cavity 78 for removal of interface adapter 62 of a type dedicated to interfacing one function, fox audio/video output, and substitution therefor of a different one of the plurality of dedicated interface adapters, such as interface adapter 62 of a type dedicated to interfacing device synchronization or another function.
In operation, adapter housing 76 is positioned adjacent to J-cup receiver 34 of receiver structure 20, with plug outlet plate 84 adjacent to in interface portion 66 of J-cup receiver 34, and opening 80 substantially aligned with aperture 64. Plug 72 of interface adapter 62 is projected through outlet aperture 86 in outlet plate 84 by urging of threaded adjusters 68. Thereafter, the electronics device is received into J-cup receiver 34, whereupon its I/O port is coupled with interface adapter 62. J-cup receiver 34 of receiver structure 20 tilted back toward bearing surface 18 of tray body 16 into the clamped state. The electronics device is seated in docking tray 12 by pressing the electronics device toward bearing surface 18 of tray body 16 against resistance of resiliently pivotable preload levers 40, until the electronics device encounters clip or roller 30 at end of neck 28. The electronics device is pushed inwardly past clip or roller 30 and until the electronics device deforms neck 28 sufficiently to permit passage there past. When the electronics device is seated against bearing surface 18, flexible neck 28 of tray body 16 resiliently reforms around the electronics device with the clip or roller 30 pressing it into firm contact with interface portion 66 of J-cup receiver 34 and interface adapter plug 72 through residual tension in deformed tray neck 28.
FIG. 7 and FIG. 8 are close-up cross-section views of docking station 10, wherein details of universal adapter module 14 are more clearly shown. Compression plate 88 is shown here as a movable plate that is slidable along a channel 100 formed in internal cavity 78. Compression plate 88 has an aperture 102 sized to pass adapter cord or cable 74 of interface adapter 62 while obstructing passage of adapter body 70, for example by interfering with a shoulder portion 70b thereof. Threaded adjusters 68 of the means for urging movable compression plate 88 is, for example, in threaded engagement with compression plate 88. Channel 100 is configured with means for aligning adapter body 70 within internal cavity 78 and adapter plug 72 with outlet aperture 86 in outlet plate 84. For example, channel 100 is formed with a keyway 104 and compression plate 88 is formed with a mating key 106 moveable therealong. Accordingly, turning of threaded adjusters 68 moves compression plate 88 along internal cavity 78, while key 106 in mating keyway 104 forces motion of compression plate 88 substantially linearly along internal cavity 78 toward (arrow 94) or away from (arrow 96) adapter opening 80 of housing 76, and positions adapter plug 72 in outlet aperture 86 in plug outlet plate 84 positioned therein.
Access plate 98 is more clearly shown as a plug engaged in another opening 108 through housing 76 and providing access into internal cavity 78 for changing between different ones of the plurality of interface adapters 62 dedicated to supporting different functions.
While the preferred and additional alternative embodiments of the invention have been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention. Therefore, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention. Accordingly, the inventor makes the following claims.
