Field access station

Abstract

A field access station for housing and protecting an electronic display system in a sealed compartment in a first configuration and in a positively-pressurized compartment having a controlled outflow flow of filtered air in a second configuration.

What is claimed is: 
     
         1 . A system for displaying construction documents in electronic format in a high-dust industrial environment, the system comprising:
 an enclosure for housing a display screen and sealable from dust, the enclosure being sealable to minimize dust infusion and including:
 a front panel, a top panel, a back panel, and two side panels, each of the panels being coupled to an adjacent panel with a sealed edge to form a sealed enclosure, at least one of the panels including an intake vent to allow a flow of intake air there through; 
 a first aperture in the front panel for viewing an electronic display; 
 a transparent pane mounted over the first aperture and an outside perimeter of the first aperture for viewing the electronic display there through; 
 a second aperture in the front panel for accessing an interior of the enclosure; 
 a movable cover mounted over the second aperture and sealable around an outside perimeter of the second aperture in a closed position and movable away from the front panel to expose the second aperture in an open position; 
   an electronic display mounted within in the enclosure and visible through the first aperture;   a blower mounted adjacent the intake vent and having an air filter, the blower being operable to direct an intake flow of air through the air filter and into the enclosure; and   a tray slidably amounted with the enclosure and extendable from a retracted position within the enclosure through the second aperture to an extended position, the tray having a rear panel operable to seal against an inside perimeter of the second aperture with the tray in an extended position, the rear panel having a plurality of outlet holes formed therein and configured to direct an outlet flow of filtered air over the tray.   
     
     
         2 . The system according to aspect  1 , wherein the enclosure further comprises:
 a second plurality of outlet holes formed into the front panel;   an air diverter mounted proximate the second plurality of outlet holes and configured to direct a second outlet flow of filtered air over the transparent pane; and   a second movable cover configured to seal over the second plurality of outlet holes in a closed position and to expose the second plurality of outlet holes in an open position.   
     
     
         3 . The system according to aspect  1 , wherein the enclosure further comprises a blower cut-out switch configured to remove power to the blower with the tray in the retracted position. 
     
     
         4 . The system according to aspect  1 , wherein the enclosure is itself a movable cart, or is coupled to a movable cart. 
     
     
         5 . The system according to aspect  1 , further comprising a computer device located in the tray and in electrical communication with the electronic display.
