Description:
BACKGROUND AND SUMMARY OF THE INVENTION 
     This invention relates to a desk type apparatus for housing components of a micro and personal computer comprising a CPU (central processing unit), a monitor and a printer unit. The central processing unit often houses disc drives. 
     For many years, great technological advances have been made in data and word processing equipment. At the present time, many new and improved computer type word processing systems are being marketed. 
     However, acceptable developments of new and improved work station equipment have not kept pace with the development of data processing and computer equipment. While some attempts have been made to satisfy the long known need for new and improved work station equipment, to date, there has been no generally satisfactory solution. Some of the prior art attempts are illustrated in the following United States patents: Foster U.S. Pat. No. 4,313,112 and Clayton et al. U.S. Pat. No. Des. 236,351. 
     A substantial improvement in such work station equipment is disclosed in co-pending United States patent application Ser. No. 580,804, filed Feb. 16, 1984, of E. C. Schairbaum now U.S. Pat. No. 4,590,866. However, the foregoing improvement does not satisfy the demand for low cost, highly efficient work station equipment. 
     In general, the present invention comprises a work station unit having an appearance resembling a conventional desk, but which is capable of housing a cathode ray tube (CRT) type computer display terminal unit, a central processing unit (CPU) usually including the disc drive, a keyboard unit, and a printer unit in a new and improved manner. The top panel of the desk is provided with a central transparent section enabling viewing of the CRT unit which is mounted below the transparent desk top panel on adjustable support means. The keyboard unit is mounted in a central desk drawer for movement between a retracted stored position beneath the desk top panel and an extended operating position. The printer unit is mounted in a first side drawer for movement between a retracted stored position beneath the desk top panel and an extended operating position. The CPU (central Processing unit) which includes the disc drive is mounted in a second side drawer unit for movement between a normal retracted stored position beneath the desk top panel and an extended position for access thereto. Additional drawer units or storage space may be provided for paper, storage disks and work product materials.

     DETAILED DESCRIPTION OF THE INVENTION 
     In general, as shown in FIG. 1, the apparatus and system of the present invention comprises a desk-type work station means 20 having an upper top panel means 22 with a transparent central panel portion 24; a pair of spaced pedestal means 26, 28 including one or more slidable drawer unit means 30, 31 mounted in storage space means 33, 34, a central slidable drawer means 35, a central space means 36, and a central CRT support means 38 located beneath the central transparent panel portion 24. 
     The construction and arrangement of the work station unit is such as to enable an operator to sit on a chair means (not shown) in front of the central space means 36 and have access to and operate various component units of a conventional word processing, computer-type system. A conventional CRT display means unit 42 is adjustably mounted on the central CRT support means 38 in a position enabling viewing by the operator through the transparent central panel portion 24. A conventional printer means unit 44 is mounted in one of the side drawer means 30. A conventional central processing unit, CPU means unit 46, is mounted on another one of the side drawer means 31. A conventional keyboard-type data input means 48 is supported in the central drawer means 35. Conventional overhead door means 50, 52 are movable from a stored overhead horizontal position to beneath top panel means 22 to a vertical position housing storage space means 33, 34 and may be provided with suitable locking means (not shown). Central drawer means 35 may also have such locking means. 
     In operation, as shown in FIG. 1, central drawer means 35 is pulled outwardly to an operating position for access to the data input means 48. Door means 50 is raised and drawer means 30 is pulled outwardly to an operation position for access to printer means 44. Door means 52 is raised to provide access to CPU means 46. Movable shelf means 31 normally remains in the retracted position during operation of the system, but may be pulled outwardly to enable full access to the CPU means 46. The position of the CRT unit may be adjusted for a particular operator by outward movement of CRT support means 38 for access to the adjustment apparatus. Then, the CRT support means 38 is pushed back into central space 36 beneath glass portion 24. When the work station is not in use, the printer drawer means 30 may be closed and door means 50 may be lowered and locked; central drawer means 35 may be closed and locked; and CPU door means 52 may be lowered and locked. 
     A storage space means 54 for paper or the like 56 may be provided below an adjustable printer unit means shelf 58. A central vertical panel 60 in storage space 34 provides a compartment 62 for CPU means 46 and may be adjustably mounted to accommodate different size CPU units. The other space maybe divided by adjustable shelf members 64 and 66. The door and drawer track and roller mechanisms and shelf and panel adjustment mechanisms are conventional. Also, the general desk construction mounting and fastening elements are also conventional. In general, the desk unit comprises top horizontal panel means 22; spaced laterally extending vertical panel means 70, 72, 74, 76 which define spaces 33, 34, 36; and a longitudinally extending vertical front panel means 78 which may be made of conventional desk materials such as wood or metal or the like. A plurality of openings 80 in the front panel means 78 for permitting the movement of conditioning air into storage space means 33 and 34 and central space means. Also, the front panel means is provided with handle means 82. 
     The CRT support means 38 is illustrated more specifically in FIGS. 3 and 4 and comprises a U-shaped base frame 84 formed from hollow, rectangular channel 86 and covers 88 for closing the open ends of the channel 86. A plurality of casters 90 are secured by swivel means 92 to the U-shaped base frame 84, so that it may be rolled over a supporting surface. The U-shaped base frame 84 is located generally in a horizontal plane with the open end of the U-shaped frame 84 facing the operator of the apparatus. 
     Extending in a vertical direction upwardly from and secured to the base member 94 of the U-shaped base frame 84 are a pair of spaced apart hollow support tubes 96. A cylindrical member 98 is positioned for slidable movement in each of the hollow support tubes 96. Means, such as the locking set screws 100, are provided to secure the cylindrical members 98 at any desired position in the support tubes 96. It is understood that means other than the set screw 100 may be used to secure the cylindrical members 98 at any desired location in the support tubes 96. Also, it is understood that the foregoing cross-sectional configurations of the channel 86, the support tubes 96 and the cylindrical member 98, are for description purposes only and may comprise other cross-sectional configurations. 
     A U-shaped support bracket 102 is secured to the upper end 104 of end cylindrical member 98 with the open end of the U-shaped support bracket 102 facing upwardly. A support shelf 106 is provided for supporting a CRT. A plurality of U-shaped channel members 108 are secured to the bottom surface 110 of the shelf 106 with the open ends of the U-shaped channel members 108 adjacent to the bottom surface 110. The base 112 of each of the U-shaped channel members 108 has an outer width W less than the inner width W 1 , of the base 114 of each of the U-shaped support brackets 102 so that each U-shaped channel member 108 may be nested in each U-shaped support bracket 102. 
     The means for pivotally mounting the shelf 106 on the U-shaped support brackets 102 is illustrated in an exploded veiw in FIG. 3 and in an assembled view in FIG. 4. Each U-shaped channel member 108 is provided with a pair of aligned openings 116 and each U-shaped support bracket is provided with a pair of aligned openings 118. As illustrated in FIG. 4, each U-shaped channel member 108 is nested in one of the U-shaped support brackets 102 so that the openings 116 are aligned with the openings 118. A bolt 120 is passed through the aligned openings 116 and 118. A plurality of lock washers 122, located as illustrated in FIG. 4, are used in conjunction with a nut 124 to retain the shelf in a desired angular relationship with the U-shaped support brackets 102. It is understood that this angular relationship may be changed as desired by simply loosening the nuts 124, moving the shelf 106 to a different angular relationship and then tightening the nuts 124. Means (not shown) may be provided for locating and retaining a CRT in a desired location on the upper surface of the shelf 106. 
     The CRT support means 38 illustrated in FIG. 3, permits the CRT support means to be moved to any desired location within a three dimensional field and rotation about a horizontal axis and a vertical axis. The relationship of the cylindrical members 98 and the support tubes 96 permits the vertical adjustment of the CRT display unit 42 while the swivelly mounted casters allow for movement in any direction in a horizontal plane. The pivotal means, illustrated particularly in FIG. 4, permits the angular adjustment of the CRT display unit about a horizontal unit. However, the structure illustrated in FIG. 3 provides for only limited movement about a vertical axis obtained primarily by the swivel mounting of the casters 90. If additional movement around a vertical axis is desired, only one support tube 96 and one cylindrical member 98 is used. The support bracket secured to the cylindrical member 98 would be shaped to provide two spaced apart U-shaped support brackets having aligned openings similar to the aligned openings 118. This modified structure would permit pivotal movement about both a vertical axis and a horizontal axis. 
     It is to be understood that the drawer units may be used to house or store other elements such as paper, storage discs and work product materials. Also, the desk-type work station means may be supported on casters so as to be movable in all directions. 
     It is contemplated that the inventive concepts herein described may be variously otherwise embodied and it is intended that the appended claims be construed to include alternative embodiments of the invention except insofar as limited by the prior art.
