Description of the Preferred Embodiment
With reference now to the drawings, and in particular to FIGS. 1 to 7 thereof, a new and improved computer terminal apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
FIG. 1 illustrates a prior art work station organization 1, wherein a fixedly mounted chair 2 is mounted within the module, including control panel support 4 and a monitor 3 arranged in a fixed relationship relative to the chair structure, as set forth in U.S. Pat. No. 4,695,903.
FIG. 2 illustrates a further prior art seating arrangement, wherein the organization 5 is of a generally ovate configuration mounted upon a swivel base 7, wherein the organization includes a seat 6 fixedly mounted within the ovate housing utilizing various control panels and speakers mounted within the housing, as set forth in U.S. Pat. No. 4,826,245.
More specifically, the computer terminal apparatus 10 of the instant invention essentially comprises a "U" shaped base 11, including a rear base leg 11a in a parallel relationship to a forward base leg 11b. A seat member 12 is mounted on the "U" shaped base and mounted at an acute angle upon the rear base leg of 11a and extending forwardly to the forward base leg 11b at an intersection therewith below the mounting of the seat member 12 with the rear base leg 11a. The seat leg portion 13 of the seat 12 is mounted to the forward base leg 11b as illustrated below the "L" shaped torso support portion of the seat 12 that is mounted fixedly upon the upper terminal end of the rear base leg 11a. A padded lumbar projection 14 mounted medially of the "L" shaped seat torso support portion includes a control rack 15 operative with a control pinion 16 to adjust projection of an arcuate lumbar support plate 17 within the lumbar projection 14. A vertical slot 18 mounting the control rack and pinion 15 and 16 permits vertical adjustment of the lumbar support adjustment organization. A plurality of arm rests are also mounted for use with the organization. A neck support 19 is provided which may be pivotally mounted (not shown) for contour adjustment of a neck portion of an individual.
The assembly includes a key board support shelf 20 that projects interiorly of the "U" shaped base 11 and mounts a computer key board 21 thereon. A computer terminal shelf 22 is mounted above and rearwardly of the key board support shelf 20 and mounts the computer terminal 23 thereon between spaced parallel computer terminal shelf sidewalls 22a. A monitor shelf 24 mounts a monitor 25 thereon, with the monitor shelf 24 defining an acute angle 27 defined between the monitor shelf 24 and the computer terminal shelf 22 to angulate the monitor towards the torso portion of the seat 12 to arrange the forward face of the monitor generally parallel relative to the torso portion of the seat. Monitor shelf side walls 26 enclose the monitor for securement thereof. The backwall, relative to the monitor shelf, is open for proper ventilation of equipment mounted thereon.
FIGS. 4 and 5 illustrate the use of a modified key board support plate 28 that includes a plate flange 29 integrally and orthogonally mounted to a lower terminal end thereof and projecting upwardly thereof to mount the key board 21 thereon. The mounting base member 30 fixedly mounts the organization to a computer terminal shelf side wall 22a and includes a first, second, and third rigid link 31, 32, and 33. The first rigid link 31 is orthogonally and fixedly mounted to the mounting base member 30. The first rigid link is pivotally and adjustably mounted to the second pivot link 32 by a first socket joint 34. A second socket joint 35 adjustably amounts the second rigid link 32 to the third rigid link 33. The third rigid link 33 is adjustably mounted to a bottom surface of the key board support plate 28 by a third socket joint 36. Each socket joint includes a ball 37 rotatably mounted within a semispherical socket 38. A threaded rod member 39 radially projects interiorly of the socket to fixedly secure the ball 37 in a predetermined angular orientation relative to the socket 38.
FIGS. 6 and 7 illustrate the use of a modified monitor support organization wherein bifurcated side walls 40 define upper terminal ends of the terminal shelf side walls 22a. Clamp connectors 41 rotatably adjust a monitor hood support 42 relative to the bifurcated side walls 40. Parallel hood side walls 43 are orthogonally mounted to opposed sides of a floor 46. A rear end wall 47 defines an enclosure with a forward opened end wall opening 48 to position the associated monitor 25 within the enclosure or hood support 42. The top wall 45 and the bottom wall 46 each include overlying and aligned terminal ends, with a top wall clamp pair 48 and a floor clamp pair 49 orthogonally projecting through the top wall and floor adjacent the forward terminal ends thereof. Each clamp of the top clamp pair 48 is coaxially aligned with underlying respective clamp of the floor clamp pair 49. Each clamp includes a threaded detent rod 50 orthogonally directed through the top wall or floor, with the handle member 51 integrally and orthogonally mounting an upper terminal end of each detent rod 50. A polymeric resilient clamping sphere 52 is fixedly mounted to a lower terminal end of each rod 50 to fixedly secure a monitor between the plurality of clamp pairs to permit rotation of the hood support 42 in a desired angular orientation relative to the computer terminal shelf 22 that remains at an acute included angle 27.
As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall 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.
