Table with a Rotatable Board

Abstract

A table includes a board, a supporter, a pivot shaft and a lock mechanism. The supporter is disposed on the board. The pivot shaft is disposed on the supporter, and the board is rotatably disposed on the supporter via the pivot shaft. The lock mechanism is disposed between the board and the supporter. The board is switched between a first position and a second position. The lock mechanism fixes the board on the supporter when the board is switched to the first position, and the lock mechanism sets the board parallel to the supporter when the board is switched to the second position.

What is claimed is: 
     
         1 . A table comprising:
 a board;   a supporter disposed on the board for supporting;   a pivot shaft disposed on the supporter, the board being rotatably disposed on the supporter via the pivot shaft; and   a lock mechanism disposed between the board and the supporter, wherein the board is switched between a first position and a second position, the lock mechanism fixes the board on the supporter when the board is switched to the first position, and the lock mechanism sets the board parallel to the supporter when the board is switched to the second position.   
     
     
         2 . The table of  claim 1 , wherein the lock mechanism comprises:
 a connecting component disposed on the board, the connecting component comprising an engaging slot and a pushing portion, the engaging slot being parallel to the pushing portion, an opening of the engaging slot being adjacent to the pushing portion;   an engaging component movably disposed on the supporter; and   a spring contacting against the engaging component, wherein when the board is switched to the first position, the pushing portion pushes the engaging component to move into the engaging slot via the opening, and the spring contacts against the engaging slot to fix the board relative to the supporter; when the engaging component balances a resilient force of the spring to move to a position corresponding to the opening, the board is rotatable to move the engaging component away from the engaging slot via the opening, and the board is switched from the first position to the second position.   
     
     
         3 . The table of  claim 2 , wherein the lock mechanism further comprises:
 a frame fixed on the supporter, the frame comprising a constraint slot whereinside the engaging component is movably disposed, a movement of the engaging component being constrained by the constraint slot; and   a guide pillar disposed on the frame and passing through the engaging component, the spring being sheathed on the guide pillar, two ends of the spring respectively contacting against the frame and the engaging component.   
     
     
         4 . The table of  claim 3 , wherein the connecting component is combined with the frame when the board is switched to the first position. 
     
     
         5 . The table of  claim 3 , wherein the pivot shaft passes through the frame and the connecting component. 
     
     
         6 . The table of  claim 3 , wherein the lock mechanism further comprises:
 a pull bar connected to the engaging component, the board being rotatable when the engaging component moves to a position corresponding to the opening by pulling the pull bar.   
     
     
         7 . The table of  claim 1 , wherein the lock mechanism comprises:
 a frame fixed on the supporter, the frame comprising a constraint slot whereinside the engaging component is movably disposed, a movement of the engaging component being constrained by the constraint slot; and   a guide pillar disposed on the frame and passing through the engaging component, the spring being sheathed on the guide pillar, two ends of the spring respectively contacting against the frame and the engaging component.   
     
     
         8 . The table of  claim 1 , further comprising:
 a plurality of feet connected to the supporter.   
     
     
         9 . The table of  claim 1 , wherein the board is parallel to a ground when the board is switched to the first position. 
     
     
         10 . The table of  claim 1 , wherein the board is perpendicular to a ground when the board is switched to the second position.
