     This application claims the benefit of U.S. Provisional Application No. 60/812,793, filed Jun. 12, 2006, entitled WALL MOUNTED WORKSTATION, which is hereby incorporated herein by reference in its entirety. 
    
    
     BACKGROUND OF THE INVENTION 
     The present invention relates to a workstation assembly, and in particular to a wall-mounted workstation assembly that operably supports a computer monitor and a computer keyboard and that provides both coupled and individual manipulation and maneuvering thereof. 
     Workstation assemblies adapted to support computer monitors and/or computer keyboards encompass a wide variety of designs that are adapted to be used in various work settings. Many of these designs are specifically adapted to be used within a particular work environment. One such work environment is that dictated by the medical field. Specifically, numerous advancements in electronic patient information allow medical practitioners easy and updated access to complete medical records and the latest patient information. While information can be accessed through conventional desktop and lap top computers located within a medical facility, patient care is optimized by providing such access to these medical practitioners within the patient care rooms themselves, rather than requiring the care giver to retreat to an office setting to gather such information. Approaches to providing such interface within patient rooms has included mobile carts, as well as wall mounted units. However, as floor space within most medical facilities is at a premium, large mobile units typically go unused due to the lack of space and their cumbersome design. Further, previous wall-mounted units are also typically large in design and cumbersome to use. Moreover, these units do not provide adequate maneuverability or adjustability to the caregiver to allow easy access to the information, and/or to allow the caregiver to easily share information and images with other physicians attending to the patient, or with the patient themselves. 
     There is a need for a workstation assembly that provides adequate maneuverability and adjustability so as to facilitate easy access and interaction with the computer equipment being supported, and sharing among numerous individuals, while simultaneously reducing the overall amount of required floor space or general space within the room.

The second friction collar  186  as press fit within the inner diameter  190  of the mounting member  188  receives the first friction collar  184  therein such that a second frictional force is exerted between an inner diameter  187  of the second friction collar  186  and the outer diameter  189  of the first friction collar  184 . It is noted that the first friction is greater than the second friction, such that in operation, rotational movement of the keyboard support assembly  164 , by exerting a force thereon, that pivots the support post  166  results in an equal rotation of the monitor support assembly  162 . However, as the second frictional force is less than the first frictional force, a rotation of the computer monitor  11  support assembly  162  by exerting a force therein does not result in a rotation of the computer keyboard  13  support assembly  164 . Such a configuration allows a person such as a healthcare provider to continue to access or input information via the supported computer keyboard  13  while allowing other persons within the vicinity, such as other positions or the patient, to observe the supported computer monitor  11 . 
     The computer keyboard  13  support assembly  164  includes the boom arm  174  having an aperture  194  that fixedly receives the second end  172  of the support post  166  therein. A proximal end  196  of the boom arm  174  includes a pair of flanges  198  each having a pivot aperture  200  extending therethrough. A keyboard tray assembly  202  includes a pivot bracket  204  that includes a pivot aperture  205 , and a housing bracket  206  that is fastened to an underside of the pivot bracket  204  to shroud the same. The pivot bracket  204  is pivotally connected to the boom arm  174  by a pivot pin  208  that extend through the pivot apertures  200  of the boom arm  174  and the pivot aperture  205  of the pivot bracket  204 . The keyboard tray assembly  202  further includes a keyboard tray  210  ( FIGS. 25-30 ) secured to and operably supported by the pivot bracket  204 . The keyboard tray includes a keyboard support surface  212 , an elevated worksurface  214  positioned above the keyboard support surface  212  and a plurality of walls  216  spaced along the width of the keyboard support surface  212  and located proximate a rearward edge  218  thereof. 
     The computer keyboard  13  support assembly  164  further includes a cam assembly  220  ( FIGS. 22-24 ) including a cam hub  222  integrally formed with the pivot bracket  204  to pivot about an axis  224  defined by the pivot pin  208 . The cam hub  222  includes a detent  223  located thereabout. The cam assembly  220  further includes a leaf spring  226  fixedly coupled to a boss  228  integrally formed with and extending downwardly from the boom arm  174 . The leaf spring  226  includes a curved end portion  230 . In operation, the end portion  230  of the leaf spring  226  guides along and frictionally engages the cam hub  222 . In the illustrated example, the detent  223  is located along the cam hub  222  such that the leaf spring  226  engages the detent  223  to hold the pivot bracket  204  and the keyboard tray  210  in a substantially-vertically oriented storage position ( FIG. 22 ). The keyboard tray  210  is pivotable through a range of motion including the storage position, an intermediate position, ( FIG. 23 ), and a lowered in-use position ( FIG. 24 ). In addition, the pivot joint about the pivot pin  28  may be configured to exact frictional engagement between the pivot bracket  204  and the boom arm  174 , thereby assisting the cam assembly  220 . 
     As is best illustrated in  FIG. 25 , the keyboard support surface  212 , the separate worksurface  214  and the walls  216  cooperate to form a pocket or compartment  232 . The keyboard support surface  212  and the worksurface  214  are each preferably comprised of molded plastic. In the illustrated example, the keyboard support surface  212  is sized so as to allow not only placement of the supporting computer keyboard  13  thereon, but also an area located forwardly of the pocket  232  that is large enough to manipulate a computer mouse thereon. The pocket  232  is sized and positioned to slidably receive the computer mouse therein when the keyboard tray  210  is moved from the in-use position to the storage position, thereby eliminating the need to remove the mouse from the keyboard support surface  212  each time the workstation assembly  10  is moved into a storage position against the wall  14 . Tapered walls  234  assist in guiding the computer mouse into the pocket  232 . The pockets  232  are each trimmed with a trim strip  235 . 
     The keyboard support assembly  164  further includes an actuator handle  240  ( FIGS. 25-27 ) pivotably coupled to the keyboard support tray  210 . The handle  240  is coupled to the valve tab  131  via a bowden wire  241 , thereby allowing the operator to remotely actuate the pneumatic cylinder  120  and adjust the overall height of the workstation assembly  10 . Specifically, the bowden wire  241  is connected at a first end  250  thereof to a linkage assembly  252  housed within a stamped metal housing  253  and including an arm  254  pivotally coupled to the actuator handle  240  at a first end  256 , and pivotably coupled to a pivot member  258  at a second end  260 . The pivot member  258  is pivotably coupled to the keyboard support tray about a pivot axis  262 . A second end (not shown) of the bowden cable is coupled to the valve tab  131  of the pneumatic cylinder  120  such that pivoting of the actuator handle  240  actuates the valve of the pneumatic cylinder  120 , thereby allowing the user to vertically adjust the support arm assembly  16  and the vertical position of the supported computer monitor  11  and computer keyboard  13 . 
     Alternatively, the keyboard tray  210   a  ( FIGS. 28-30 ) comprises a keyboard support surface  212   a , a separate worksurface  214   a  and walls  216   a  that cooperate to form a pocket or compartment  232   a , and comprise almost entirely molded plastic, without the use of an insertable metal housing  253 , as discussed above. As the keyboard tray  210  and the keyboard tray  210   a  are similar in construction, the same corresponding reference numerals are used for both except the suffix “a” in the numerals of the latter. In the illustrated example, the keyboard support assembly  164  further includes an actuator handle  240  pivotably coupled to the keyboard support tray  210   a . The handle  240   a  is coupled to the valve tab  131   a  via a bowden wire  241   a , thereby allowing the operator to remotely actuate the pneumatic cylinder  120   a  and adjust the overall height of the workstation assembly  10   a . Specifically, the bowden wire  241   a  is connected at a first end  250   a  thereof to a linkage assembly  252   a  housed within a stamped metal housing  253   a  and including an arm  254   a  pivotally coupled to the actuator handle  240   a  at a first end  256   a , and pivotably coupled to a pivot member  258   a  at a second end  260   a . The pivot member  258   a  is pivotably coupled to the keyboard support tray about a pivot axis  262   a . A second end (not shown) of the bowden cable is coupled to the valve tab  131   a  of the pneumatic cylinder  120   a  such that pivoting of the actuator handle  240   a  actuates the valve of the pneumatic cylinder  120   a , thereby allowing the user to vertically adjust the support arm assembly  16   a  and the vertical position of the supported computer monitor  11   a  and computer keyboard  13   a . It is noted that the components and members of the linkage assembly  252   a  are mounted to and within the keyboard tray  210   a  without use of a separated mounting housing. 
     The workstation assembly  10  further includes a handle  242  ( FIG. 1 ) having a base portion  244  mounted to the computer monitor  11  support assembly  162  and a pair of grips  246  extending vertically along the sides of the supported computer monitor  11 . The grips also allow easy manipulation and adjustment of the computer monitor  11  without requiring direct grasping of the same.
