Abstract

A computer housing or case contains computer system components including a display unit, a processor, and a computer power supply unit. One or more handles are positioned at a side of the case to allow a user to hold the encased computer system while viewing the display. A case has a support interface structure to hold the case steady in an upright position. The support interface structure of the case mates with a complimentary support interface in the weight-supporting base unit and mates with guides to align a power supply port in the case to contact a power supply port in the base unit. A base unit has a keyboard guide to receive a keyboard by lifting the keyboard above a support surface. A modular computer system comprises a tablet computer, a base unit, and a remote keyboard. A first infrared communication device couples the tablet computer to the remote keyboard and other input peripherals. A second infrared communication device couples the tablet computer to a remote printer. A radio frequency network adapter couples the tablet computer to the base unit, which provides additional communications to an external communications network.

a second handle including said second side surface, said second front surface, and a second grip positioned on said back face of said case near said second side;

wherein said second handle is graspable by a second hand of said user such that at least one finger of said second hand is capable of engaging said second grip, the palm of said second hand is capable of contacting said second side surface, and said second hand is capable of contacting said second front surface while said user can view said display unit through said see-through portion of said case.

3. The housing of

claim 1

wherein said first grip is nonplanar with said back face.

4. The housing of

claim 1

wherein said first grip comprises a recess formed in said back face substantially parallel to said first side of said case.

5. The housing of

claim 1

wherein said first grip comprises a grip structure protruding from said back face near said first side of said case.

6. The housing of

claim 1

wherein said case has a top side and a bottom side, and said first grip comprises a recess formed into said back face from said top side to said bottom side substantially parallel along the entire length of said first side.

7. The housing of

claim 1

wherein said first grip comprises a hole through said case capable of receiving said at least one finger to allow said first hand to wrap completely around said handle.

8. The housing of

claim 1

further comprising a support structure operably attached to said case that holds said case upright on a support surface.

9. The housing of

claim 8

wherein said support structure is a stand disposed in a stand recess in said back panel that extends from said back panel to support said case.

10. The housing of

claim 8

wherein said support structure folds into a recess in said back panel to form a portion of said first grip in said back panel.

11. A housing for containing a computer system having a display unit, a processor unit, and a computer power supply unit therein and for engaging a weight-supporting base unit having a base unit guide and a base power supply port, said display unit being viewable by a user, said housing comprising:

a case having opposing front and back panels;

said front panel having a see-through portion that allows said display unit to be viewable from outside said case;

a case power supply port formed in said case positioned to engage an electrical lead coupled to said computer power supply unit;

an interface structure formed in said case, wherein said interface structure is capable of detachably engaging said case to said weight-supporting base unit and holding said case steady in an upright position; and

a case guide positioned on said interface structure, wherein said case guide is capable of complementarily engaging said base unit guide to align said case power supply port with said base power supply port.

12. The housing of

claim 11

wherein said interface structure comprises a tab formed in said case, wherein said tab is capable of mating into a slot formed in said weight-supporting base unit.

13. The housing of

claim 11

wherein said case guide is a recessed area having a lip on one of said panels that is capable of complementarily sliding against a support tab in said weight-supporting base unit to horizontally align said case power supply port to correspond with said base power supply port.

14. The housing of

claim 11

wherein said case guide is a recessed structure formed in said back panel being capable of complementarily engaging said base unit guide that protrudes from said weight-supporting base unit.
