Handheld electronic communication device transitionable between compact and expanded configurations
View Patent ↗A handheld electronic communication device is disclosed that is transitionable between at least a compact configuration and expanded configuration. The handheld electronic communication device includes a display panel pivotally interconnected to a keyboard panel. The display panel can be overlaid on, and in substantial registration with, the keyboard panel in a compact configuration. Furthermore, the display panel can be offset above the keyboard panel in an expanded configuration. A pivot connection can be configured to couple and maintain the keyboard and display panels in substantial parallel orientation to each other in the compact and expanded configurations. The pivot connection includes an axis of rotation and is located in an upper corner of the handheld electronic communication device in the compact configuration. Additionally, a trackball navigation tool assembly is located at the upper corner of the handheld electronic communication device where the axis of rotation is located.
1. A handheld electronic communication device transitionable between at least compact and expanded configurations, said handheld electronic communication device comprising:
a display panel pivotally interconnected to a keyboard panel, wherein said display panel is overlaid on, and in substantial registration with, said keyboard panel in the compact configuration and said display panel is offset above said keyboard panel in the expanded configuration;
said display panel coupled to said keyboard panel by a pivot connection configured to maintain said display panel and keyboard panel in substantial parallel orientation to each other in the compact and expanded configurations and during transition between the compact and expanded configurations, said pivot connection comprises an axis of rotation and is located in an upper corner of the handheld electronic communication device in the compact configuration and said axis of rotation is oriented substantially perpendicular to said display panel and keyboard panel; and
a navigation tool assembly located at the upper corner of the handheld electronic communication device at which said axis of rotation is located.
2. The handheld electronic communication device as recited in claim 1 , wherein said navigation tool assembly further comprises a spherical trackball having a center point substantially aligned with the axis of rotation of the pivot connection.
3. The handheld electronic communication device as recited in claim 1 , wherein the handheld electronic communication device presents a substantially square front profile in the compact configuration.
4. The handheld electronic communication device as recited in claim 1 , wherein the handheld electronic communication device presents a substantially rectangular front profile in the expanded configuration.
5. The handheld electronic communication device as recited in claim 1 , wherein the handheld electronic communication device is right-hand operable with the pivot connection located in a top right-hand corner of the handheld electronic communication device in the compact configuration.
6. The handheld electronic communication device as recited in claim 1 , wherein the handheld electronic communication device is left-hand operable with the pivot connection located in a top left-hand corner of the handheld electronic communication device in the compact configuration.
7. The handheld electronic communication device as recited in claim 2 , wherein a front face of the handheld electronic communication device adjacent said trackball is contoured downward toward the trackball.
8. The handheld electronic communication device as recited in claim 2 , further comprising a cover surrounding the trackball, wherein the cover is contoured downward toward the trackball.
9. The handheld electronic communication device as recited in claim 1 , wherein said display panel includes a touch sensitive display screen.
10. The handheld electronic communication device as recited in claim 1 , wherein said keyboard panel has a keyboard comprising a plurality of alphabetic keys with one alphabetic letter per alphabetic key.
11. The handheld electronic communication device as recited in claim 1 , wherein said keyboard panel has a keyboard comprising a plurality of alphabetic keys wherein a majority of said plurality of alphabetic keys have more than one alphabetic letter per alphabetic key.
12. The handheld electronic communication device as recited in claim 2 , wherein said display panel further comprises at least one key radially aligned with a center point of the trackball.
13. The handheld electronic communication device as recited in claim 12 , wherein said at least one key is located on a proximate side of a front face of the display panel.
14. The handheld electronic communication device as recited in claim 13 , wherein said at least one key is a menu key.
15. The handheld electronic communication device as recited in claim 13 , wherein said at least one key is an escape key.
16. The handheld electronic communication device as recited in claim 13 , wherein said at least one key is a call key.
17. The handheld electronic communication device as recited in claim 1 , wherein said pivot connection further comprises at least one stop to align the display panel substantially above said keyboard panel in the compact configuration.
