Brief Patent Description - Full Patent Description - Patent Application Claims
FIELD OF THE INVENTION [0001]The present invention relates generally to display panel mountings and more particularly to a system and methodology for mounting a selectively movable display screen to a base section of an electronic device. BACKGROUND OF THE INVENTION [0002]As a result of the development of small portable computer devices, almost everyone has come to use and rely upon some type of electronic device such as a "laptop" personal computer (PC). Laptop computers and other electronic devices have become so versatile that they are used for many different applications, both business and personal. For example, a laptop computer may be used simply as a word processor or as a movie screen able to play video files from a CD. [0003]Laptop computers generally include a keyboard unit and a display unit which are hinged together by a single fixed hinging system which couples the bottom of the display unit and the top of the keyboard unit. The display unit is selectively rotated to an open position to enable a user to work on the keyboard and view the user input on the display screen. Other electronic devices, such as CD players, may not require a full keyboard but operate in the same manner by rotating a display screen to an open position in order to view a video file presentation. [0004]In many situations however, there is little if any space behind a laptop to allow the display panel to fully open. For example, in an airplane seat, the seat directly in front of a laptop user is reclined at an angle to make it extremely difficult if not impossible to fully open the display screen of a laptop computer or other display device such as a CD player. If the laptop is moved closer to the user so that the screen can be partially viewed, the keyboard portion of the laptop is so close to the user that it is practically impossible to efficiently work on the keyboard. [0005]Thus, there is a need for an improved system and methodology for enabling a user to open a display screen of an electronic device in a confined space and to comfortably work the keyboard while, at the same time, having a full view of the display screen. SUMMARY OF THE INVENTION [0006]A method and system are provided in which a display screen of an electronic device such as a laptop computer is double-hinged to a base or keyboard unit in such a manner as to allow the display screen to be opened while the bottom portion of the display screen is free to rotate toward a user to enable the user to view the display screen when little or no space is available at the rear of the display screen. In an exemplary embodiment, a double-hinged arrangement is provided at the sides of the laptop such that there is access to the keyboard when the display screen is rotated upwardly and the bottom of the display screen is moved toward the user. In an exemplary embodiment, a first hinged sidebar couples the lower portion of the display screen with the lower portion of the keyboard unit and a second hinged sidebar couples the upper portion of the display screen with the upper portion of the keyboard unit. The hinged sidebars are positioned at the sides of the laptop to allow access to the keyboard unit when the laptop is fully opened. The first hinged sidebar is a telescoping sidebar which may be compressed and extended to position the display screen at a comfortable viewing angle relative to the user. BRIEF DESCRIPTION OF THE DRAWINGS [0007]A better understanding of the present invention can be obtained when the following detailed description of a preferred embodiment is considered in conjunction with the following drawings, in which: [0008]FIG. 1 is a side view of a laptop computer illustrating the hinged sidebar arrangement of the present invention; [0009]FIG. 2 is an illustration showing a laptop computer in a partially open position on a tray table of a reclining front seat; [0010]FIG. 3 is an illustration showing a laptop computer in a fully open position on a tray table of a reclining front seat; [0011]FIG. 4 is a top view of a laptop computer showing the double hinged sidebars on each side of the computer; and [0012]FIG. 5 is an illustration showing an exemplary embodiment of a hinged telescoping sidebar which may be implemented in an exemplary usage of the present invention. DETAILED DESCRIPTION [0013]It is noted that devices which are shown in block or schematic form in the drawings are generally known to those skilled in the art, and are not specified to any greater extent than that considered necessary as illustrated, for the understanding and appreciation of the underlying concepts of the present invention and in order not to obfuscate or distract from the teachings of the present invention. Also, throughout the drawings, like numerals refer to the same parts. While the illustrated example refers to a laptop computer, it is understood that the principles disclosed herein apply equally as well to any electronic device which includes a display screen designed to be rotated around a fixed base axis to an open position. [0014]In FIG. 1, a laptop computer 101 is illustrated. The laptop 101 includes a display screen 103 and a keyboard 105. The bottom 107 of the keyboard 105 is hinged through a first hinged variable-length sidebar 111 to the bottom 109 of the display screen 103. The bottom 109 of the display screen 103 is hinged through a second fixed-length sidebar 117 to the bottom 107 of the keyboard 105. The variable-length sidebar 111 includes a telescoping design and can be extended or compressed by a user to move the bottom 109 of the display screen 103 relative to the bottom 107 of the keyboard 105 as is later described in connection with FIG. 5. The double-hinged arrangement shown in FIG. 1 is implemented on both sides of the laptop computer for stability. The hinges securing the sidebars to the display screen and the keyboard may be any of many well known designs to enable a rotating movement as illustrated. As shown in FIG. 1, the laptop may be opened and closed in a normal manner by simply rotating the display screen 103 upwardly without compressing the variable-length sidebar 111. However, when there is little or no space available behind the laptop, the double-hinged design and the variable-length hinged sidebar 111 may be used to allow a full view of the display screen 103 while also allowing use of the keyboard 105. [0015]As shown in FIG. 2, when the laptop computer 101 is placed on a tray table 203 of a reclined seat 201 in front of a user, such as frequently happens in an airplane, it is difficult to fully open the laptop computer or any other device which includes a single-hinged, rotate-to-open display screen. However, with the illustrated double-hinged arrangement, a display screen may be opened to a position where the entire screen may be viewed. As illustrated, as the display screen 103 is rotated open 207, a user may force the variable-length sidebar 111 to compress 205 to allow the bottom of the display screen to be moved toward the bottom of the keyboard 105 of the laptop computer 101 while the fixed-length sidebar 117 guides the rotation 207 of the top of the display screen 103. [0016]FIG. 3 illustrates the open position of the laptop computer shown in FIG. 2. In FIG. 3, the variable-length sidebar 111 has been compressed 301 to a point such that the display screen 103 is positioned above the keyboard 105 and disposed at an angle to allow a user full view of the display. Since the display is above the keyboard and the sidebars are along the sides of the laptop, a user may place his or her hands inside of the sidebars 111 to access and work on the keyboard 105. [0017]FIG. 4 shows a top view of a laptop 101 in a closed position, including the display unit 103 with the variable length sidebars 111 and fixed-length sidebars 117 positioned along side of the laptop computer 101. [0018]FIG. 5 illustrates an exemplary embodiment of a variable-length or telescoping sidebar 111. As shown, a first bar element 501 is slideably engaged within a second bar element 503. The first bar element includes a first hinge component 109 arranged for engagement with a corresponding hinge at the bottom of the display screen and the second bar element 503 includes a second hinge component 107 arranged for engagement with a corresponding hinge at the bottom of the keyboard as described in connection with FIG. 1. In the example, element 501 is designed to slide within element 503 with moderate force which might correspond to, for example, sliding or extending an antenna of a car radio. The frictional pressure between the first and second bar elements 501 and 503 is such as to allow movement of element 501 relative to element 503 but for bar element 501 to retain its position relative to bar element 503 when no user force is applied. Other arrangements to accomplish this slidable telescoping function may also be implemented. [0019]The method and apparatus of the present invention has been described in connection with a preferred embodiment as disclosed herein. The disclosed methodology may be implemented in a wide range of designs and embodiments to accomplish the desired results as herein illustrated. Although an embodiment of the present invention has been shown and described in detail herein, along with certain variants thereof, many other varied embodiments that incorporate the teachings of the invention may be easily constructed by those skilled in the art. Accordingly, the present invention is not intended to be limited to the specific form set forth herein, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents, as can be reasonably included within the spirit and scope of the invention.
