Description
- 1. Field of Invention
- This invention relates to an ergonomically designed work station which supports computer peripherals in a location compatible with a user and supports the user in a position which minimizes stress on the human body.
- 2. Description of Related Art
- Conventional computer work stations consist of a desk having a location for mounting of a computer monitor, a keyboard and a computer tower. The user generally sits on an office chair in front of the monitor. Such arrangements have been notorious for inducing back pain, carpel tunnel syndrome and other problems. A few workstations were designed attempting to integrate human comfort and health with performance. However, such workstations have been made up of many different parts interconnected or free standing. Moreover, some of these parts typically block off access by a user to a chair. Moving such systems involves moving awkwardly interconnected elements such as a chair and a desk as well as free standing stands for holding monitors and side tables.
- Another problem with current workstations is the failure to interconnect various functions of the workstation. For example, for a workstation having a foot rest, any tilting function of the chair requires a separate adjustment of the foot rest in order for the latter to be compatible with the new position of the chair. A similar comment applies to the keyboard and mouse trays.
- Finally, the manufacturability of workstations tends to be difficult because of the large number of parts and the complexity of various mechanical movements.
- It is an object of the invention to provide an ergonomic workstation in which the entire workstation is integrated and the user area is accessible from the front.
- According to the invention there is provided a modular work station having a base module, a lower spine and chair support module affixed to said base, a chair assembly module removable positioned on said chair support; and an overhead support module removably affixed to said lower spine and positioned over a head of a user.
- The advantage of this modular construction is that each module is largely self-contained and can be made and tested independently of the other modules and then finally assembled and tested as a unit.
- The chair assembly may have a foot rest assembly affixed thereto and positioned to receive and support a user's feet when the user is in the chair assembly.
- The chair assembly may have a keyboard tray and arm rest assembly affixed thereto.
- The chair assembly may have an adapter bracket to which is affixed a chair controller, the foot rest assembly, a seat, and a keyboard tray and arm rest assembly.
- Tilting of the chair may cause simultaneous tilting of the keyboard tray and arm rest assembly and the foot rest assembly.
- A lower spine may be attached to the base by lower gusset plates and an overhead support attached to said lower spine by upper gusset plates, said lower and upper gusset plates acting to dampen vibration of said lower spine and overhead support module.
- Monitor gusset plates may be attached to a distal end of the overhead support and support a video monitor.
- A table may be attached to the lower spine at one end and supported at another end by the base.
- Adjustable supports may be affixed to respective arm rests and be capable of raising and lowering the arm rests.
- The foot rest assembly may comprise a foot rest slider assembly pivotally coupled at one end to a foot rest plate and having slider plates on either side slidable within respective ones of a pair of elongated slots.

The leg rest frame plates 112 pivot aboutpivot pin 113. The gas springs 52 are connected between ahole 95 in the side of theadapter bracket 49 and a hole 96 in the leg rest frame plates 112. As gas springs 52 extend, they cause leg rest frame plate 112 to pivot so thatfoot rest 22 is raised. As the leg rest frame plate 112 pivots thefoot rest 22 upwardly as seen inFIGS. 10-12 , theslider plate stabilizer 67 moves downslider plate slot 77 towards the end closest to thefoot rest 22 causing thefoot rest 22 to lengthen slightly so as to accommodate the natural extension of the leg. - Referring to
FIG. 13 , theadapter bracket 49 is made up of two parallel side plates 114, joined across the top by twobridge plates 115. Lowerarm rest plate 83 fits onadapter bracket 49 between thebridge plates 115 to which the former is welded. - Referring to
FIGS. 14 to 18 , akeyboard tray 24 is rotatably attached to a tray rod 116 (seeFIG. 15 ) and clampable by means of a clampingknob 93. A right-hand mouse pad andarm rest assembly 27 is also rotatably attached to tray rod 116. An armrest upper plate left 37 has two holes which fit overpem studs 108 extending through mouse armrest tray 110 and are affixed to a bottom of mouse armrest tray 110. Anarmrest trigger plate 102 is attached to the armrest upper plate 107 by means of pair of arm rest lock springs 104. Spacer discs 111 separate the mouse armrest tray 110 from the mouse arm rest upper plate 107 both of which are rotatably attached to tray rod 116. A contouredarm rest 40 fits atop mouse arm rest upper plate 107 together with anadjacent neoprene pad 109. Referring toFIG. 18 keyboard tray 24 has peripheral holes which receive countersunk screws 101. Screws 101 have threads which register with the threads of the keyboard tray top plate 99. Aneoprene pad 98 fits over the keyboard tray top plate 99 (seeFIG. 18 ). Akeyboard tray lip 100 is screwed to the bottom ofkeyboard tray 24. - Referring to
FIGS. 9 and 15 , the left and right arm rests 38 and 40, respectively, are controlled by a series of plates coupled to theadapter bracket 49. Arm restupper plate 37 has four vertically oriented elongated slots 117 at each corner and a pair of parallel short slots 118 in the center. Anarm rest trigger 102 is attached to arm restupper plate 37 by means of arm rest lock springs 104. Armrest trigger plate 102 has V-shaped slots 119 which overlap with parallel slots 118. Arm restupper plate 37 is screwed to an underside of mouse arm rest tray 107 as can be seen inFIG. 15 . Locking pins 120 are inserted into the parallel slots 118 and held in place. The protrusion on each locking pin 120 extends through the V-shaped slot and the slots in the adjacent plate into the slots in theadapter bracket 49 which have a serrated edge. Pulling up on the trigger plate causes the protrusions to release from the serrated sides of elongated slots in theadapter bracket 49 and the arm restupper plate 37 to move upwardly. Downward movement is also possible if the arm restupper plate 37 is already in an elevated position. - A
chair controller 58 shown inFIG. 19 , is a standard controller available commercially having a plurality of levers 60 to control various functions of a chair including pivoting of the whole chair aboutshaft 43. - Referring to
FIGS. 20 and 21 , thecompression assembly 79 has atiltable handle 71 that compresses and decompresses acompression assembly 79. The compression of acompression lock 92 which consists of a series of fingers spaced apart by thin washers. The compression ofcompression lock 92 causes thecompression lock 92 to clamp ontosleeve 103 which is threadedly engaged with a long threaded rod (not shown) that also threadedly engages a sleeve 81 that is locked from rotation by apin 82. Thus, when compressed,compression lock 92 is locked against rotation aboutsleeve 103 and prevents rotation of rotatingrod 91. This, in turn, prevents movement of linkage 73. - Referring to
FIGS. 22 and 23 theback rest 20 of the chair has a series of adjustment holes 124 formed in anattachment 130 which the back rest frame plates slide over. Spring loadedpins 126 engage a set of holes which depends upon the vertical positioning of theback rest 20. Ahead rest 86 attaches to theattachment 130 and so moves with theback rest 20.Attachment flange 128 is insertable into a slot in thechair controller 58. - It will be appreciated that workstation 10 is made up of 4 different modules namely, the chair assembly, the spine-base assembly, the tray and arm rest assembly and the upper spine assembly. The lower spine and base are assembled first, the chair assembly is assembled next and positioned over the tapered inner
rotatable shaft 43 and the tapered outercylindrical housing 41. Next table 88 is affixed to thespine 14 andbase 12 bytable support 90. Finally, theoverhead support 30 is installed. - A user enters the chair 10 by pivoting the
keyboard tray 24 to open the centre region either from the left-hand side or from the right-hand side. Any adjustments to themonitors 34 and to the height of chair 16 required for the user are made. Adjustment to the position of the foot rest can be made by moving the tilt handle 71 pulling out spring loadedpins 54 and sliding moveable plates 70 until a desired positioning offoot rest 21 is achieved. The entire workstation 10 can be moved by simply rolling it oncasters 44. Since all peripherals are affixed tobase 12, there is no need to move separate elements of the workstation 10. - Various features of the several different embodiments of the invention described herein may be used in combination with other features described herein to produce combinations of features other than those specifically described above and such combination are intended to be within the scope of this invention.
