Screen transportation device

Abstract

A screen transportation device has a frame; a carrier being movable between a first position and a second position; a linkage having one end pivoted with a first connecting part on the carrier and another end slid along and pivoted with the frame; and a guiding device pivoted with a second connecting part on the carrier and being movable in the frame; wherein the carrier is able to pivot with the second connecting part on the carrier between a first angle and a second angle.

1 . A screen transportation device comprising: 
 a frame;    a carrier being movable between a first position and a second position;    a linkage having one end pivoted with a first connecting part on the carrier and another end slid along and pivoted with the frame; and    a guiding device pivoted with a second connecting part on the carrier and being movable in the frame;    wherein the carrier is able to pivot with the second connecting part on the carrier between a first angle and a second angle.    
   
   
       2 . The screen transportation device as claimed in  claim 1 , wherein the frame is formed as a case, and has an opening on front side and a space to install the carrier.  
   
   
       3 . The screen transportation device as claimed in  claim 2 , wherein the frame has a guide, and the guide is mechanically connected with the linkage.  
   
   
       4 . The screen transportation device as claimed in  claim 3 , wherein the guiding device is slid inside of the frame and movable backward from and forward to the opening.  
   
   
       5 . The screen transportation device as claimed in  claim 4 , wherein the guiding device is driven with an actuator to move among the first position where the carrier is wholly inserted in the frame, the second position where the carrier is moving out of the frame, and a third position where the carrier arrives at the second angle.  
   
   
       6 . The screen transportation device as claimed in  claim 5 , wherein the actuator comprises a motor.  
   
   
       7 . The screen transportation device as claimed in  claim 6 , wherein the carrier comprises a liquid crystal display.  
   
   
       8 . The screen transportation device as claimed in  claim 7 , wherein the guide is formed as a slot.  
   
   
       9 . The screen transportation device as claimed in  claim 7 , wherein the guide is formed as a slot, and the linkage is pivot on a slider that is slid in the slot.  
   
   
       10 . A screen transportation device comprising: 
 a case having an opening on a front side, a slot, and a space;    a carrier installed in the case;    a linkage having one end pivoted with a first connecting part on the carrier, and another end mechanically connected with the slot and slid along the slot a required distance; and    a guiding device pivoted with a second connecting part on the carrier and being movable in the case a required distance;    wherein the sliding stroke of the guiding device is longer than the longitudinal distance of the slot, and the guiding device, the linkage, and the carrier move along in a same direction.    
   
   
       11 . The screen transportation device as claimed in  claim 10 , wherein the guiding device is driven with an actuator to move among a first position where the carrier is wholly inserted in the frame, a second position where the carrier is moving out of the frame, and a third position where the carrier arrives at the second angle.  
   
   
       12 . The screen transportation device as claimed in  claim 11 , wherein the carrier comprising a controller that can command the actuator so that the carrier moves among the first position, the second position, and the third position.  
   
   
       13 . The screen transportation device as claimed in  claim 12 , wherein the actuator comprises a motor.  
   
   
       14 . The screen transportation device as claimed in  claim 13 , wherein the carrier comprises a liquid crystal display.  
   
   
       15 . The screen transportation device as claimed in  claim 14 , wherein the linkage is pivot on a slider that is slid in the slot.  
   
   
       16 . A screen transportation device comprising: 
 a case having an opening on a front side, a slot, and a slider being movable with a specific stroke in the slot;    a carrier installed in the case;    a linkage having one end pivoted with a first connecting part on the carrier, and another end mechanically connected with the slider slid along the slot; and    a guiding device pivoted with a second connecting part on the carrier and being movable with a specific stroke in the case;    wherein the sliding stroke of the guiding device is longer than the slider, and the guiding device, the slider, and the carrier move in a same direction.    
   
   
       17 . The screen transportation device as claimed in  claim 16 , wherein the guiding device is driven with an actuator to move among a first position where the carrier is wholly inserted in the frame, a second position where the carrier is moving out of the frame, and a third position where the carrier arrives at the second angle.  
   
   
       18 . The screen transportation device as claimed in  claim 17 , wherein the carrier comprising a controller that can command the actuator so that the carrier moves among the first position, the second position, and the third position.  
   
   
       19 . The screen transportation device as claimed in  claim 18 , wherein the actuator comprises a motor.  
   
   
       20 . The screen transportation device as claimed in  claim 19 , wherein the carrier comprises a liquid crystal display.
