FIELD OF THE INVENTIONThe invention relates to the field of information processing systems, and more specifically to a notebook computer having a resilient, portfolio-type case. The invention has particular application to the IBM® ThinkPad® line of notebook computers (IBM and ThinkPad are registered trademarks of the International Business Machines Corporation, Armonk, N.Y.).[0001]
BACKGROUND OF THE INVENTIONThere are a number of portfolio-type notebook computers (see U.S. Pat. Nos. 5,607,054 and 5,887,723 and the references cited therein). A general problem is that portfolio type cases generally provide protection but the computer is often removed from the case during use such that the case must be stored in a location away from the computer.[0002]
SUMMARY OF THE INVENTIONThe present invention solves this problem by making the portfolio case a permanent part of the notebook computer. The case not only protects the computer but provides structural support for its elements.[0003]
The invention provides a rugged, attractive folio-type case folded along a line to form opposed halves. A slide fastener is attached around the periphery to provide secure closure. A large flat-panel display module is built into one opposed half, while a processor-keyboard module is built into the opposite half. The modules are interconnected using inexpensive flex cable routed between the units along the fold.[0004]
The processor-keyboard includes a large wrist rest area below the keyboard providing operating buttons for a built-in pointing device. An external pointing device is attachable via a PS/2 type connector. The angle between the display and the keyboard is adjustable by user positioning of the slide fastener slider near the fold region. To increase the angle, the slider is moved closer to the fold; to decrease the angle, the slider is moved a small amount in the opposite direction.[0005]
A protective lip and crushable corners formed by an extension of the protective cover beyond the edges of the keyboard and display provides added protection against mechanical shock.[0006]
A removable, multipurpose writing pad is attachable at either end of the computer case to accommodate the needs of both left- and right-handed users. The writing pad folds under the case when not used. It is attached by snap button to the bottom of the computer for transport, and is foldable over the keyboard for protection in the open position such as while being used at a desk or table top. When removed and inserted between the display and the keyboard during transport, the writing pad protects both the display and the keyboard from damage.[0007]
Advantages of the invention are the simple adjustment of the angle of display, the use of an inexpensive flex cable to interconnect the functional modules, the crushable corners and protective extending lips, the possibility of using a very large flat panel display because of increased room within the case, the removable, multipurpose writing pad, the fact that the carrying case doesn't have to be stored during use and so is impossible to lose, and an attractive, rugged case that has an estimated life of 2-3 years.[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTWith reference to FIG. 1, there is shown a front perspective view of a notebook computer having a resilient, portfolio-type case displayed in an open position. The notebook computer is designated, generally, by the[0018]reference numeral100 and includes a portfolio-type case102, a processor-keyboard assembly104, aflat display assembly106, aninterconnecting cable assembly108, awrist rest area110, and aslide fastener112.
The portfolio-[0019]type case102 is preferably made of a resilient, protective material folded along a line to form opposed halves. The folded protective material defines an open position (shown) in which the opposed halves of the portfolio-type case support theflat display assembly106 and the processor-keyboard assembly104 in a notebook computer relationship with respect to one another. As used here, the phrase “notebook computer relationship” means that thedisplay106 is located above the processor-keyboard assembly104 so that a person using the notebook computer is able to look directly into the display while using the keyboard for typing and commanding the computer. The folded protective material also defines a closed position (illustrated in FIGS. 3, 4 and5) in which the twoassemblies104,106 are enclosed within the protective portfolio-type case102. The interconnectingcable assembly108 connects the two computer assemblies together to form a fully functional notebook computer.
FIG. 2 is a front perspective view of the folder resilient, protective material used to form the case for the notebook computer illustrated in FIG. 1. The folded material is designated generally by the[0020]reference numeral200. Thematerial200 is folded about afold line202 to form twoopposed halves204,206 respectively.
A plurality of structural supports[0021]208-218 and220-230 are disposed on the two opposed halves of the folded,protective material200. In a specific embodiment of the invention, as shown in FIG. 2, the structural supports208-218 are formed of molded plastic and include a support base232. In similar manner, the structural supports220-230 are formed of molded plastic and include a support base234. Each support base232,234 is bonded to an opposed half,204,206 respectively, of the foldedmaterial200. In another specific embodiment, the structural supports208-218 (220-230) and included support base232 (234) are formed of machined metal such as aluminum. In a specific embodiment, each structural support208-230 includes a threaded bore for easily attaching other structural elements using screws. In yet another embodiment, each structural support208-230 includes a bore-like recess suitable for use with self-tapping screws and the like. The bore-like recess is molded into a structural support to reduce the manufacturing cost.
The resilient, protective portfolio-type case[0022]102 (FIG. 1) provides a framework upon which the notebook computer is assembled. This framework is distinguished from a typical portfolio carrying case used for some notebook computers. In such devices (see for example U.S. Pat. Nos. 5,607,054 and 5,887,723) a notebook computer having its own plastic or metal case is stored inside a protective, portfolio-type cover. In the present invention, however, the computer is actually built into the portfolio-type case, just as a notebook computer is normally built into its plastic or metal protective case. In the usual notebook computer, the protective case provides structural support for a display assembly and a processor-keyboard assembly which are interconnected by cable. The case retains the two assemblies in the typical “notebook computer relationship” with each other. In the present invention, the same purpose is served by the portfolio-type case and the structural support members. Specific advantages of the present invention—in addition to its durability and attractive appearance—are that when the computer is in use, its case does not have to be stored in another location and, as a result, is not forgotten or misplaced.
FIG. 3 is another front perspective view of the notebook computer of FIG. 1 shown in a nearly closed position. The computer is designated generally by the[0023]reference numeral300, and includes a foldedprotective case302, aslide fastener304,display module306, and processor-keyboard module308. The attachment of theslide fastener304 to an outer edge of thecover302 creates aprotective lip310 extending outwardly along the entire slide fastener.
FIG. 4 is a top view of the notebook computer of FIGS.[0024]1-3 shown in a closed position. The computer is designated generally by the numeral400, and includes an outer, protective cover of aresilient material402 havingprotective lips404 along three edges, and afold406 along a fourth edge. The configuration createscrushable corners408. Theprotective lips404, fold406, andcrushable corners408 provide additional protection to the functional modules within the computer case. The dashedline410 represents attachment of the slide fastener to the cover material, while the long-short dashedline412 represents an outline of the functional modules within the computer case. The protective lips, fold and crushable corners are seen to extend significantly beyond the periphery of the functional modules, providing increased protection to the two modules.
FIG. 5 is an end view of the notebook compute of FIGS.[0025]1-4 shown in a closed position. The computer is designated generally by the numeral500, and includes aslide fastener502 and aslider504.
FIG. 6 is a partial end view of the notebook computer of FIGS.[0026]1-5 showing details of the slider used to adjust an angle between the display and the keyboard. The portion of the computer shown is designated generally by the numeral600, and includes a foldedcover602 shown in an open position, aslide fastener604, a slider606 adjacent afold608. A portion of a processor-keyboard module610 is visible. A portion of a display module is represented by a dashedline612.
The slider[0027]606, the material of theslide fastener604, and the resilient material of the foldedcover602 all cooperate to maintain theangle614 between the display and the keyboard in a relatively fixed relation. To decrease the angle, the slider606 is moved farther away from thefold608, while to increase the angle, the slider is moved closer to the fold. In an alternative embodiment, astrap616 of fixed length is used to limit a backward travel of the display with respect to the keyboard for a predetermined viewing angle. The strap is attached at opposed ends to thedisplay module612 and the processor-keyboard module610, respectively, and folds when the case is in the closed position.
FIG. 7 is a plan view of the bottom of the notebook computer showing details of a detachable, multipurpose writing pad. The computer is designated generally by the[0028]reference numeral700, and includes a bottom portion of a protective portfolio-type case702, a detachablemultipurpose writing pad704,snap buttons706, mating snaps708, retainingflaps710,magnets712, and coveredmagnetic material714.
The[0029]writing pad704 is approximately the size of the bottom702 of thecomputer700. Foursnap buttons706 are located near the corners of thewriting pad704. Four mating snaps708 are located near the corners of the bottom702 of the computer. Thewriting pad704 is connectable to the bottom of the computer by attaching all foursnap buttons706 tomating buttons708. The writing pad is also attachable to either end of the computer for use by both left- and right-handed persons. When attached at one end, two of thesnap buttons706 engage two of themating buttons708, as illustrated, permitting thepad704 to extend from one end to one side of the computer for use as a writing surface and for using an external pointing device (not shown).
Two retaining[0030]flaps710 extend from opposed sides of themultipurpose writing pad704. The retaining flaps are made of a flexible material and are foldable over the writing pad for retaining papers.Magnets712 located within each retaining flap and coveredmagnetic material714 located within thewriting pad704 hold each retaining flap in a retaining position during use in retaining writing materials on thepad704. The retaining flaps are usable for retaining paper placed on either surface of themultipurpose writing pad704.
FIG. 8 is a perspective view of the notebook computer showing the use of the writing pad of FIG. 7 to protect the keyboard when the case is in an open position. The notebook computer is designated generally by the numeral[0031]800, and includes a processor-keyboard module802, aprotective cover804, a detachable,multipurpose writing pad806, opposed retainingflaps808,concealed magnets810, and concealedmagnetic material812.
The[0032]writing pad806 is shown in a writing/working position extending from one end of the computer. When the computer is being used on a desktop, thewriting pad806 is folded (arc814) across the keyboard to form aprotective cover816. When the writing pad is not being used, the retainingflaps808 are first folded under thewriting pad806, and then the writing pad is folded under the computer (arc818) for storage. The writing pad is retained in a position under the computer by the snap buttons located at its corners (FIG. 7).
