Elevating device for planer displayer

Abstract

An elevating device includes a facility, such as a planer displayer slidably received in a housing and movable outward of the housing in an outward working position and inward of the housing in an inward storing position for allowing the displayer to be covered and shielded in the housing and to be prevented from being dirtied. A pneumatic or hydraulic actuator or a motorized elevating device is disposed in the housing for moving the monitor in and out of the housing. One or more posts are disposed in the housing for guiding the object to move up and down along the posts.

I claim:  
     
         1 . An elevating device comprising: 
 a housing including an upper portion having an opening formed therein,    an object slidably received in said housing, and    means for moving said object inward of said housing in an inward storing position and outward of said housing in an outward working position.    
     
     
         2 . The elevating device according to  claim 1 , wherein said object is a displayer.  
     
     
         3 . The elevating device according to  claim 2 , wherein said object is a planer displayer.  
     
     
         4 . The elevating device according to  claim 1 , wherein said moving means includes an actuator having a tube secured to said object, and means for activating said tube to move inward and outward through said opening of said housing.  
     
     
         5 . The elevating device according to  claim 4 , wherein said activating means includes a motor disposed in said housing and having a bolt extended therefrom and threaded to said tube for moving said tube and said object up and down when said bolt is rotated by said motor.  
     
     
         6 . The elevating device according to  claim 4  further comprising means for guiding said tube to move up and down relative to said housing.  
     
     
         7 . The elevating device according to  claim 6 , wherein said guiding means includes a casing secured in said housing and having an orifice formed therein for slidably receiving and guiding said tube.  
     
     
         8 . The elevating device according to  claim 1  further comprising means for guiding said object to move up and down relative to said housing.  
     
     
         9 . The elevating device according to  claim 8 , wherein said guiding means includes at least one post vertically disposed in said housing, a seat slidably secured to said at least one post for supporting said object and for guiding said object to move up and down along said at least one post.  
     
     
         10 . The elevating device according to  claim 1  further comprising a table including an aperture formed therein, said housing being secured to said table, said object being aligned with said aperture of said table for allowing said object to be moved up and down through said aperture of said table.
