Foldable desk top file or tray device

Abstract

A tray device includes a base plate having two side panels each of which has two spring latches, and two boards each having a lower portion pivotally secured to the base plate with a pivot shaft, and to be rotated between an upward working and a downward folding positions. The spring latches of the side panels may be engaged with the boards to latch and retain the end boards at the upward working position relative to the base plate. The base plate includes a fence to engage with one of the boards, and to retain the board at the upward working position. One of the pivot shafts may be disposed higher than the other pivot shaft to support one of the boards higher than the other board.

1 . A tray device comprising: 
 a base plate including two side panels extended upwardly therefrom and including two end portions, each of said side panels including two ends each having a spring latch extended therefrom respectively, and    two boards each including a lower portion pivotally secured to said end portions of said base plate with a pivot shaft respectively, to allow said boards to be rotated relative to said base plate between an upward working position and a downward folding position,    said spring latches of said side panels of said base plate being engaged with said lower portions of said boards respectively when said end boards are rotated relative to said base plate to said upward working position, to latch and retain said end boards at said upward working position relative to said base plate, and said end boards being rotatable relative to said base plate to said downward folding position when said spring latches are depressed relative to said side panels and disengaged from said lower portions of said boards respectively.    
   
   
       2 . The tray device as claimed in  claim 1 , wherein said base plate includes a fence extended upwardly from a first end portion of said two end portions thereof, to engage with said lower portion of a first board of said two boards, and to retain said first board at said upward working position relative to said base plate.  
   
   
       3 . The tray device as claimed in  claim 1 , wherein a first pivot shaft of said pivot shafts is attached to a first end portion of said two end portions of said base plate, to pivotally secure a first board of said two boards to said base plate, and a second pivot shaft of said pivot shafts is attached to a second end portion of said two end portions of said base plate, to pivotally secure a second board of said two boards to said base plate.  
   
   
       4 . The tray device as claimed in  claim 3 , wherein said first pivot is disposed higher than said second pivot shaft, to allow said second board to be engaged onto said first board after said first board is rotated toward and to engage with said base plate.  
   
   
       5 . The tray device as claimed in  claim 1 , wherein each of said end portions of said base plate includes at least one first duct attached thereto, each of said boards includes at least one second duct attached to said lower portion thereof and aligned with said at least one first duct of said base plate, to receive said pivot shaft respectively, and to rotatably secure said end boards to said base plate.  
   
   
       6 . The tray device as claimed in  claim 5 , wherein said base plate includes a fence extended upwardly from a first end portion of said two end portions thereof, to engage with said lower portion of a first board of said two boards, and said at least one first duct of said base plate is secured to said fence of said base plate.
