Abstract:

Description:
BACKGROUND OF THE INVENTION 
     Conventional case for storing floppy disk for computor use is designed to put all disks together into the case in a way like a card-index system used in a library. However, such a conventional case has the following defects: 
     1. The disks are crowded or overlapped within the case whereby the insertion or withdrawal of a disk among the piles of disks is inconvenient and will take time. The abrasion caused between the contacting surfaces of the disks will deteriorate the disks and influence the precision of the disks. 
     2. The discription label adhered on the disk which is vertically standing and put into disk case can be read when stored in disk case. However, when the disk is put into disk drive for computer operation, the words description on disk will become reversed to the reader or operator and thus increase inconvenience for the user. 
     3. A conventional disk case is made from plastic material. The disk stored in the plastic case will be interfered in a surrounding having magnetic flux to reduce the precision of the disk. 
     The present inventor has found the defects of conventional disk case and invented the present collapsible storage box for floppy disk. 
     SUMMARY OF THE INVENTION 
     The object of the present invention is to provide a collapsible storage box for floppy disk including a casing, a switch means and a plurality of collapsible storage bags retractably formed in the casing, whereby the switch means is actuated to open a cover of the casing and the storage bags will be automatically extended for taking a disk out from the bag in a more convenient way without abrasing the disk.

     DETAILED DESCRIPTION 
     As shown in the figures, the present invention comprises a casing 1 having an upper cover 12 and a bottom case 11, a switch means 2 and a collapsible storing means 3. 
     The upper cover 12 is pivotedly mounted on the rear wall plate 111 of bottom case 11 by a hinge which comprises several hinge holes 112, 121 and several restored springs 14 jacketed in pin 13 to restore upper cover 12 in an opening tendency. An extension lip 122 is formed on the front edge of upper cover 12. 
     A lock 21 of switch means 2 is fixed on a hole 151 formed on the front wall plate 15 of case 11. A rectangular locking latch 212 is fixed on the inner portion of lock 21 by a nut 211 to normally face a corresponding rectangular hole 221 which is formed on the lower portion of push-button 22 to allow the normal depressing action of push-button 22. Push-button 22 is lowerly formed with two side pins 222 pivotedly fixed on two holes 162 of two brackets 161 fixed on the portion of bottom plate 16. Two extension plates 163 are formed on brackets 161 to define the backward motion of push-button 22. Push-button 22 is formed with an extension bar 223 which is jacketed with a compression spring 224 resiliently backing against the inside wall of wall plate 15. The upper portion of push-button 22 is formed with a lip hole 225 to engage with the extension lip 122 of cover 12 for closing upper cover 12 on bottom case 11. A partition plate 23 is formed to enclose the lock 21 within a compartment disposed by bottom plate 16, front wall plate 15 and plate 23 within said bottom case 11 but to project push-button 22 outwards as FIG. 2 shown. 
     A collapsible storing means 3 consists of a plurality of collapsible storage bags 31 each being formed by binding an upper transparent film 312 with a lower base plate 311 to store the floppy disk A for computor use. Each bag 31 is formed with two side wing portions 313, each being formed with a big hole 314 and a small hole 315 and a slit 316 being cut to communicate with hole 314 with hole 315. Two wires 33 tensioned by two tension springs 332 respectively are connected to two lugs 123, 167 formed on upper plate 12 and bottom plate 16. Each wire 33 is formed with a plurality of balls 331 each divided in equal distance. Wire 33 fixed with balls 331 is passing through the big holes 314 formed on the wing portions 313 and then wire 33 is moved from each slit 316 to pass through the small holes 315 to allow each ball 331 slidingly backing each bag 31 to extend all the bags 31, as a sector shape as taken from side view therefrom, when opening the upper cover 12 and pulling the wire 33. 
     The inner end of each bag 31 is terminated with a rolled portion 317 and a pin 32 which is pivotedly fixed in two pin holes 165 respectively formed on two triangle supporting plates 164 disposed on both sides of bottom plate 16. The pin holes 165 are slopingly formed on the slope side of triangle supporting plate 164 so as to form sector-type collapsible bags when extended. The number of holes 165 is the same as the number of bags 31. Each plate 164 is bent outwards to form a hook 166 to define each pin 32 and prevent its falling from the supporting plate 164. 
     The bottom case 11 is made from metals having magnetic absorbing property, to absorb magnetic flux so as to prevent from magnetic interference to the floppy disks A stored in the casing 1. 
     When opening the present invention, the push-button 22 is depressed to open upper cover 12 as restored by springs 14, the wire 33 with balls 331 will be pulled to extend all storage bags 31 to form a sector shape so that each disk A is easily taken out from each bag. When not in use, the cover 12 is closed and the lock 21 is actuated to rotate latch 212 in 90 degrees so as to obstruct the rectangular hole 221 of push button 22 whereby the button 22 can not be depressed. When retracting all bags within the casing 1, each ball 331 formed on wire 33 will separate every two neighbouring bags 31 to prevent the overlapping, abrasion between the bags. 
     The present invention has the following advantages superior to conventional disk cases: 
     1. The storage bags 31 can be opened as a sector type and the disks stored therein will be easily taken out or taken in without damaging the disks. 
     2. When retracting all bags within the casing, each bag is separated from another bag so as to eliminate the abrasion of disks during storage or handling. 
     3. The description label can be directly adhered on disk as &#34;B&#34; shown in FIG. 1 which will also be easily read when put into a disk drive due to the same reading direction. 
     4. The present invention has property to prevent from interference by magnetic flux so as to ensure the reliability and precision of the disk. 
     5. The present invention can be easily and fastly closed after opening the cover so as to have a dust-proof property. In closing state the disks originally stored in the bags will not be exposed to the outside surrounding to have a sound dust-proof effect. 
     However, the conventional disk case is difficult to open or close and whenever taking out the disk from the open case, the disk will be easily contaminated by air or environmental pollutants.
