1. Field of the Invention
The present invention relates generally to computers, and in particular to a tri-layer folding laptop computer with a built-in lectern that allows for an ergonomically correct operating posture by an individual user.
2. Description of the Related Art
The current design of laptop computers has created several problems over the years for users due mainly to functional limitations inherent in traditional two-layer construction, consisting of a screen hingedly connected to a computer base accommodating a keyboard.
Over the years, in an effort to make these laptop computers more compact and lightweight for portability, the computer manufacturers have inadvertently sacrificed comfortable ergonomic parameters of operation and long term use by individual users. Moreover, according to optometrists, the ideal focal distance most individuals prefer is in the visual range of twelve to fourteen inches from any viewing surface. Consequently, with the bi-fold design of current laptops with their keyboards positioned toward the rear of the computer base and the mouse panel situated forward, the operator is forced to lean forward with the arms suspended from the shoulders in order to both type on the keyboard and view the computer screen from a comfortable distance. The mechanical limitations inherent within this design essentially forces the operator to slump forward in an ergonomically incorrect operating position that ultimately strains the neck, shoulder and back muscles causing fatigue over time.
Additionally, in a majority of cases, operators of laptop computers usually require additional desktop space to accommodate additional paperwork and/or books to refer to while working. Consequently, by having to place these materials on a table top alongside the laptop computer in order to refer to them, the operator is forced into contorting the neck and upper body even further in order to view these items while working which contributes to the development of an even greater ergonomically incorrect working position that leads to additional neck and back muscle fatigue as well as eye strain.
The instant invention relates to a tri-layer folding laptop computer that includes a built-in lectern which creates a better working environment by allowing the operator to sit in a more ergonomically correct upright position as well as the ability to place adjunctive paperwork, music scores or books directly in front of the user while viewing the screen at approximately eye level.
Very few systems have been developed to address the problems an operator encounters during use of traditional laptop computers having only a screen for viewing screen hingedly connectable to a computer base fitted with a keyboard. Consequently, the current bi-fold design of laptop systems invariably places the viewing screen below eye level and at a less than optimal viewing distance that ultimately forces the operator to lean forward to type and to view the screen from an ergonomically undesirable sitting position.
It is therefore, the goal of the instant invention to correct the above-described problems an operator encounters during use of the traditional, bi-fold systems and, at the same time, optimize the use of available work space by incorporating a built-in lectern into the design. To this end, the preferred embodiment includes positioning the keyboard closest to the operator with the mouse panel positionable behind it in order to further facilitate ease of operation.
Presently, a large number of laptop computers, featuring differing styles, are known in the art and are widely used in the industry. But there does not exist in the art a tri-layer folding laptop computer that utilizes a built-in lectern, wherein the three folding layers consist of a viewing screen, a lectern for placing reading or work materials that are more easily accessible to the operator and a computer base with a standard size keyboard that will facilitate the operator's ability to maintain an ergonomically correct sitting position during operation of the laptop computer.
U.S. Pat. No. D443,598 to Katz discloses an ornamental design for a folding computer.
U.S. Pat. No. 5,949,643 to Batio discloses a folding, portable keyboard for a notebook computer consisting of two, pivotally-hinged halves. The two halves are hinged so that may be assume a perfectly flat, horizontal position or, alternatively, a laterally raised and sloping configuration that provides an enhanced, ergonometric configuration to the user. Furthermore, each half has its own set of keys and space bar.
U.S. Pat. No. 6,643,124 to Wilk discloses a portable computing device equipped with multiple display panels. The display panels are hinged, jointed or otherwise disposed to rotate or slide with respect to one another in a transition from a compact configuration to an expanded configuration. Therefore, in the inventions most basic embodiment three output screens take a form of a triptych for which an input panel forms a base. The output panels are deployed with a bend when opened and the images are angled in towards an observer.
U.S. Pat. No. 6,913,332 to Besterfield et al. discloses a retracting keyboard and monitor platform wherein a lift mechanism is utilized to lift a monitor, vertically, from the back of the desk. Thus, when a user is done using the system, the screen retracts and disappears.
U.S. Pat. No. 6,490,154 to Thompson discloses a mobile computer docking mechanism which transforms a laptop computer into a fully capable desktop computing and telephony system. The invention facilitates the use of the laptop liquid crystal display screen while the laptop computer is in the docked position. The network, keyboard and power ports are connected in the docked position, and the entire desktop configuration has a very low profile taking up very little desktop space. The upright position and design facilitates proper docking and an adjustable ergonomic viewing position, elevation as well as angularity.
U.S. Pat. No. 6,556,435 to Helot, et al. discloses a height adjustable docking station and a mobile computing device for use therewith. The docking station includes a structure for receiving the screen of a mobile computing device. The structure for receiving the screen is coupled to a docking station body such that the height and viewing angle of the screen in the structure can be adjusted.
In summary, investigation of these disclosed devices illustrates that presently, there is no single device known in the art that meets the requirements of a tri-layer folding laptop computer as nothing in the prior art discloses a laptop computer that utilizes a three layer structure including a viewing screen, a built-in lectern and a keyboard.
The present invention, as described further herein, imparts a novel laptop computer which encompasses the advantages of other laptop computers, but includes a tri-layer folding design that includes a built-in lectern, thereby allowing the operator to maintain an ergonomically correct, upright sitting position during use, thus overcoming problems created by the traditional bi-fold design. The instant invention, as illustrated herein, is clearly not anticipated, rendered obvious, or even present in any of the prior art mechanisms, either alone or in any combination thereof.
