A case for a PDA includes a keyboard, and a pass-through I/O port so that the PDA does not have to be removed from the case for docking. The case includes front and rear panels hinged in a clamshell configuration. The rear panel includes a docking port configured to mate with the PDA. The docking port includes an inner electrical connector configured to mate with an I/O connector on the PDA. The docking port further includes an outer electrical connector configured to mate with a docking connector on a docking cradle. The front panel includes a keyboard assembly and is movable between a closed position wherein the keyboard assembly overlies the PDA display screen and an open position wherein the keyboard is oriented for data entry and the rear panel is oriented at a viewing angle. The keyboard is segmented into a main section and first and second folding sections pivotally coupled to the main section. The main, first and second sections each include a plurality of keys respectively defining discrete portions of the keyboard assembly. The folding sections are movable between a closed position and an open position wherein the keyboard sections are joined together for operation thereof.

DETAILED DESCRIPTION Referring now to the drawings, the protective case of the instant invention is illustrated and generally indicated at 10 in FIGS.
1-10.
As will hereinafter be more fully described, the instant invention provides a unique and novel keyboard/case accessory for a handheld computer device 12, by integrating the features of a conventional QWERTY keyboard and an input/output (I/O) pass-through port in a protective case wherein the handheld computer device 12 can be substantially permanently mounted in the case 10 and so that it need not be removed from the case 10 for docking with a power/data synchronization cradle 14 (see FIG.
10).
Within the scope of the present invention, the term "handheld computer device" is intended to include, but is not limited to, personal digital assistants (PDA"s), which are typically used in conjunction with a docking cradle 14 for the purpose of synchronizing data with another computer system and/or for charging of a rechargeable battery within the device.
For ease of discussion, the terms "handheld computer device" and PDA will be used interchangeably, the disclosure is not intended to be limited by use of one term or the other.
The protective case 10 includes a front panel, generally indicated at 16, and a rear panel, generally indicated at 18, the front panel and rear panel being hinged in a clamshell configuration as best seen in FIGS.
1, and 3-5.
Referring to FIGS.
1 and 2, the PDA 12 is received between the panels 16, 18 for the purpose of covering and protecting the front and rear surfaces of the PDA 12 during use thereof.
As can be seen in FIG.
1, the front and rear panels 16, 18 are configured and dimensioned to substantially conform to the corresponding outer peripheral edges of the PDA 12 so that the case 10 does not have a substantially larger footprint than the PDA itself.
The front and rear panels 16, 18 are preferably molded, or otherwise constructed, from a substantially rigid plastic material.
However, it is to be understood that the case 10 could be constructed in whole, or in part, from other suitable materials
