Disc stand

Abstract

In a disc stand device, a pyramid-shaped or cone-shaped support column ( 2 ) is provided to be longitudinally placed in an appropriate position. A plurality of slits ( 4 ) are provided to align at regular intervals on an elevational side or a ridgeline of the support column ( 2 ) along a longitudinal direction of the support column ( 2 ). The slits ( 4 ) have a depth directed to tilt to form an acute angle against a generating line of the support column ( 2 ). Upon inserting the disc plates ( 5 ) into the slits ( 4 ), the plurality of disc plates ( 5 ) overlap partially when viewed from the user side. This enables the user to take out the desired one quickly by visually confirming the title through the gap between the disc plates ( 5 ) arranged adjacent vertically or laterally. When the disc plates ( 5 ) are applied to computer-related devices, it is possible to significantly improve an efficiency of the clerical work due to the disc plates ( 5 ) quickly taken out.

1 . A disc stand device: 
 a support column provided to be longitudinally placed in an appropriate position;    a plurality of slits provided to extend laterally and aligned longitudinally at a predetermined intervals on an elevational side or a ridgeline of said support column, each of said slits having a depth directed to tilt to form an acute angle against a generating line of said support column; and    a disc plate provided to be removably inserted at one portion into any of said slits.    
   
   
       2 . The disc stand device according to  claim 1 , wherein said support column has rectangular frames at four sides, each of said rectangular frames having a rectangular plate which said slits are provided, said rectangular plate being slidably inserted into said rectangular frame to render said rectangular plate detachable against said rectangular frame.  
   
   
       3 . The disc stand device according to  claim 1 , wherein said support column is arranged in parallel crosses with four rectangular plates, outer elevational sides of two neighboring rectangular plates having said slits.  
   
   
       4 . The disc stand device according to  claim 1 , wherein at least one side of said support column forms a slope surface to be tapered off as approaching upward, and a plurality of stepped portions are provided with said slope surface to have said slits.  
   
   
       5 . The disc stand device according to  claim 1 , wherein said support column is shaped into a truncated-pyramid configuration with the depth of said slits oriented in parallel with the generating line of said support column.  
   
   
       6 . The disc stand device according to  claim 1 , wherein a central shaft is provided in free-wheeling relationship with said support column around said central shaft.  
   
   
       7 . The disc stand device according to  claim 1 , wherein each elevational side of said support column forms a slope surface to be tapered off as approaching upward, and each of said slope surfaces has said slits.  
   
   
       8 . The disc stand device according to  claim 1 , wherein said support column is suspended in free-wheeling relationship with a central shaft provided on said support column.  
   
   
       9 . A disc stand device comprising: 
 a support column provided to have a plurality of longitudinal grooves around an elevational side of said support column;    rectangular plates, each one side of which is removably inserted into the corresponding grooves, and each of said rectangular plates having slits aligned in a longitudinal direction, a depth of which tilts to form an acute angle against a generating line of said support column; and    a disc plate provided to be removably inserted at one portion into any of said slits.    
   
   
       10 . The disc stand device according to  claim 9 , wherein said longitudinal grooves are mortises, and each of said rectangular plates has a tenon slidably fit into the corresponding mortises.  
   
   
       11 . The disc stand device according to  claim 10 , wherein opening sides of said longitudinal grooves are predetermined to be slightly wider so that said rectangular plates move in a reciprocal direction with said tenons as a central axis.  
   
   
       12 . A disc stand device comprising: 
 a support column provided to have a plurality of lateral arms in a longitudinal direction, lateral lengths of said arms being progressively longer as approaching downward;    a triangular sack secured to each distal end of said lateral arms, a depth of said sack being directed to form an acute angle against a generating line of said support column; and a disc plate provided to be removably inserted at one portion into any of said sacks.    
   
   
       13 . A disc stand device comprising: 
 a support column rectangular in cross section;    trapezoidal plates each provided at ridgelines of said support column, each slope side of said trapezoidal plates having a plurality of slits laterally extended and aligned in the longitudinal direction at the neighboring trapezoidal plates positioned in parallel each other, said slits having a depth slantwisely directed to form an acute angle against a generating line of said support column; and    a disc plate provided to be removably inserted at one portion into any of said slits.    
   
   
       14 . A disc stand device comprising: 
 a support column formed into a helically shaped configuration, said support column being diametrically smaller as approaching upward, and having a plurality of slits at predetermined intervals along a helix line of said support column; and    a disc plate provided to be removably inserted at one portion into any of said slits.    
   
   
       15 . A disc stand device according to any of claims  1 - 5 , wherein a lip plate is provided at an opening periphery of said slits so that said lip plate elastically bends to slidably admit said disc plate thereon when said disc plate is inserted into said slit.
