CD storage box

Abstract

A CD storage box includes a main box frame, a front cover, a left cover, a right cover, two turning knobs, two knob gears, a top cover, a brake shaft, multiple swing levers, a rear cover, a grip handle, a left frame and a right frame. Once the turning knobs are rotated, the knob gears can actuate the driven gears to rotate with the brake shaft and abrupt pieces on the surface of the brake gear can stir the swing levers to push CDs out for being browsed chosen.

         2 . The CD storage box as defined in  claim 1 , wherein each stand projection of the main box frame at an outer side thereof is provided with a groove for another one of the CD storage box being fixedly stacked to the storage box by way of a hook part on the left and right support frames elastically engaging with the respective groove.  
     
     
         3 . The CD storage box as defined in  claim 1 , wherein the front cover at a lower lateral side thereof is integrally made with a sector gear to mesh with the speed reduce gear and at another lower lateral side thereof next to the pin is provided with a spring groove against a leg of the torsion spring.  
     
     
         4 . The CD storage box as defined in  claim 1 , wherein the left cover is provided with a cylindrical post at a front lower side thereof corresponding to the projection to prevent the torsion spring from falling down.  
     
     
         5 . The CD storage box as defined in  claim 1 , wherein the right cover at a lower front corner has a cylindrical rib part with a small protrusion against a side face of the speed reduce gear to prevent the speed reduce gear from loosening during turning.  
     
     
         6 . The CD storage box as defined in  claim 1 , wherein the knob gear has a shaft extending axially from a lateral side thereof and a driving gear is fixedly attached to the shaft, a gear base is disposed at another lateral side opposite to the shaft with a plurality of catching hooks equally spacing apart from each other and each catching hook is next to a lateral side of a “V” shaped locating indentation respectively, the gear base has a central nest to accommodate the shaft, the locating indentation has a 90° open angle for contacting with a pressing jut of the locating spring plate, a bulge is next to the other lateral side of the locating indentation to correspond to a notch and once the bulge engages with the notch, it is not possible for the user to rotate the turning knob counterclockwise and it is possible for the knob gear to rotationally move back and forth in a free extent as long as the bulge keeps contact with the notch.  
     
     
         7 . The CD storage box as defined in  claim 1 , wherein the gear base has a plurality of locating pairs equally spaced apart from each other and each locating pair has a V shaped locating part with an open angle of 45° and two locating protrusions with about a 45° V shaped dent part between the locating projections and the locating spring plate has a about 45° slant jut corresponding to the dent part such that the knob gear can rotate clockwise only.  
     
     
         8 . The CD storage box as defined in  claim 1 , wherein the top cover at two lateral sides thereof has upper securing holes  54  for securing the right frame and the left frame.  
     
     
         9 . The CD storage box as defined in  claim 1 , wherein the support plates of the rear cover have an elongated semi-circular opening respectively to form base holes with a plurality of touching legs  55  of the top cover for holding and locating the circular projections of the swing levers and the support plates  83  at bottoms thereof have outward feet  832  corresponding to the locating grooves at the rear side of the main box frame.
