     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1-8 thereof, a new adjustable computer desk embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, it will be noted that the adjustable computer desk 10 comprises a desk 12 of any desired configuration having an upper surface 14 supported in a spaced relationship relative to a ground surface upon which the desk resides. The upper surface 14 of the desk 12 is shaped so as to define a monitor aperture 16 extending therethrough and a keyboard aperture 18 also extending through the upper surface. A monitor platform 20 is positioned within the monitor aperture 16, with a keyboard platform 22 being similarly positioned within the keyboard aperture 18. As shown in FIG. 3, the present invention 10 further comprises a monitor platform height adjustment means 24 for adjustably positioning the monitor platform 20 relative to the upper surface 14 of the desk 12. Further, a keyboard platform height adjustment means 26 is provided with the invention 10 for adjustably positioning the keyboard platform 22 relative to the upper surface 14 of the desk. By this structure, an individual can selectively position the monitor platform 20 and the keyboard platform 22 relative to the upper surface 14 of the desk 12 as desired to support a computer monitor and a computer keyboard, respectively, at desired heights relative to the upper surface. 
     As best illustrated in the cross section views of FIGS. 3 and 4, it can be shown that the monitor platform height adjustment means 24 according to the present invention 10 preferably comprises a motor bracket 28 mounted beneath the upper surface 14 of the desk 12 so as to extend across the monitor aperture 16. A monitor motor 30 is mounted to the bracket 28 and includes a motor shaft projecting towards the monitor platform 20. A threaded rod 32 is mounted to the motor shaft of the monitor motor 30 and threadably engages a threaded receiver 34 mounted to a lower surface of the monitor platform 20. The monitor motor 30 is electrically coupled to a control box 36 having a power cord 38 extending therefrom. A control switch 40, as shown in FIG. 8 for example, is electrically coupled to the control box 36 for effecting selective energization of the monitor motor 30 in both forward and reverse directions. By this structure, the monitor motor 30 can be selectively energized to rotate the threaded rod 32 so as to position the monitor platform 20 relative to the upper surface 14 of the desk 12. It should be noted that the monitor platform 20 is capable of being positioned below the upper surface 14 of the desk 12, or alternatively above the upper surface as desired. 
     Referring now to FIG. 5 with concurrent reference to FIG. 3, it can be shown that the keyboard platform height adjustment means 26 according to the present invention 10 preferably comprises a keyboard motor 42 mounted beneath the upper surface 14 of the desk 12. The keyboard motor 42 includes an unlabeled motor shaft, with a threaded rod 44 projecting from the motor shaft of the keyboard motor. As shown in FIG. 5, a threaded collar 46 is threadably engaged to the threaded rod 44 of the keyboard motor 42 and includes a projection 48 extending into a yoke 50 of a pivot rod 52. The pivot rod 52 is pivotally mounted beneath the upper surface 14 of the desk 12 and engages an elongated bracket 54 mounted beneath the keyboard platform 22. Another control switch 40, as shown in FIG. 1, is electrically coupled to the control box 36 and can be selectively actuated to operate the keyboard motor 42. By this structure, an energization of the keyboard motor 42 will effect axial movement of the threaded collar 46 along the threaded rod 44 to rotate the pivot rod 52 and cause a subsequent positioning of the keyboard platform 22 relative to the upper surface 14 of the desk 12. It should be noted that the keyboard platform 22 can be positioned beneath the upper surface 14, or alternatively, can be positioned above the upper surface 14 of the desk 12 as desired. 
     As shown in FIGS. 2, 6, and 7, the present invention 10 may further comprise a monitor platform guide means 56 coupled to the monitor platform 20 and the upper surface 14 for guiding the monitor platform into a parallel orientation relative to the upper surface. Similarly, a keyboard platform guide means 58 can be provided with the invention 10 for guiding the keyboard platform 22 in a parallel orientation relative to the upper surface 14 of the desk 12. As shown in FIG. 6 and 7, the guide means 56 and 58 are substantially similar in design and configuration and each comprise a support bracket 60 mounted beneath the upper surface 14 of the desk 12 which supports a sliding collar 62 in a substantially spaced and parallel orientation relative to the upper surface. A vertical guide rod 64 orthogonally projects from a mounting plate 66 which is secured to a lower surface of the respective platform 20 or 22. The vertical guide rod 64 projects through the sliding collar 62 to thus guide the respective platform 20 or 22 into a substantially parallel orientation relative to the upper surface 14. A securing pin 68 is preferably directed through an aperture in a lower distal end of the vertical guide rod 64 to preclude unintentional separation of the vertical guide rod 64 from the sliding collar 62. 
     In use, the adjustable computer desk 10 according to the present invention can be easily utilized to adjustably support a computer keyboard and a monitor at a desired height. 
     As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
