Tilt lock box mount system

Abstract

A TILT LOCK BOX MOUNT. The TILT LOCK BOX MOUNT enables a user to actuate a wall-mounted article such that a user may tilt the article away from the wall to any angled position between an upper and lower limit, in an easy, safe, and reliable manner.

1 . A mechanism for holding an article in a first position, a second position, and a range of intermediate positions, the mechanism comprising: 
 means for allowing motion in a first direction from said first position to said intermediate positions;    means for allowing motion in said first direction from said intermediate positions to said second position;    means for allowing motion in a second direction from said second position to said first position; and    means for preventing motion in said second direction from said intermediate positions if said article was in said first position more recently than said article was in said second position.    
     
     
         2 . The mechanism of  claim 1 , wherein said second direction is opposite to said first direction.  
     
     
         3 . The mechanism of  claim 1 , wherein said first position is a first angle, said second potion is a second angle, said first direction is a direction of angular rotation, and said second direction is a direction of angular rotation.  
     
     
         4 . The mechanism of  claim 1 , wherein the article is oriented in a greater vertical position in said intermediate position than in said first position, and the article is in a greater vertical position in said second position than in said intermediate position.  
     
     
         5 . A mechanism for holding an article in a first (position, a second position, and a range of intermediate positions, the mechanism comprising: 
 a cam adapted to rotate as the article moves from said first position through said intermediate positions to said second position;    a wedge contacting said cam, wherein said cam and said wedge are adapted to allow the article to move in a first direction from said first position to said intermediate positions and in said first direction from said intermediate positions to said second position;    a release linkage adapted to separate said wedge from said cam when the article approaches said second position and allows said wedge to contact said cam when said article approaches said first position, allowing the article to move in a second direction from said second position to said first position; and    said cam and said wedge prevent motion in said second direction from said intermediate positions when said release linkage allows said wedge to contact said cam.    
     
     
         6 . The mechanism of  claim 5 , wherein said second direction is opposite to said first direction.  
     
     
         7 . The mechanism of  claim 5 , wherein the article is adapted to be located in a greater vertical position in said intermediate position than in said first position, and adapted to be in a greater vertical position in said second position than in said intermediate position.  
     
     
         8 . The mechanism of  claim 5 , the article is a display screen.  
     
     
         9 . The mechanism of  claim 5 , further comprising a bracket system to transfer the movement of said cam to said wedge, comprising, a spring bracket, a pivot bracket, a push-pull bracket, and a wedge bracket.  
     
     
         10 . The mechanism of  claim 5 , wherein said release linkage comprises, a latch bracket, a wedge hook, and a wedge spring.  
     
     
         11 . A display device for positioning at a variety of angles, the display device comprising: 
 a display screen adapted to display a moving image received via a signal;    a mechanism adapted to support said display screen and to position said display screen in a first position, a second position, and a range of intermediate positions, the mechanism comprising: 
 a cam adapted to rotate as the article moves from said first position through said intermediate positions to said second position;  
 a wedge contacting said cam, wherein said cam and said wedge are adapted to allow the article to move in a first direction from said first position to said intermediate positions and in said first direction from said intermediate positions to said second position;  
 a release linkage adapted to separate said wedge from said cam when the article approaches said second positions and allow said wedge and said cam to contact when said article approaches said first position, allowing the article to move in a second direction from said second position to said first position; and  
 said cam and said wedge prevent motion in said second direction from said intermediate positions when said release linkage allows said wedge to contact said cam.  
   
     
     
         12 . The display device of  claim 11 , wherein the display screen is a flat panel display screen.  
     
     
         13 . The display device of  claim 11 , wherein the signal is a digital signal.
