Abstract
A base guard for use with front loading magnetic disk memory cartridge packs, is made of one piece construction, e.g., injection moulded, and formed to allow for registered, interlocked and nested vertical stacking of the memory cartridge packs and to secure the access door of the memory cartridge packs so as to prevent entry of dust particles. The base guard is formed so as not to interfere with the handle-like recesses or handholds and to prevent damage to and misalignment of the hub structure of the disk pack.
Claims8
A protector for use in stacking magnetic disk cartridges having a raised rectangular projection on its upper surface comprising:
- resilient means for removably attaching said protector to one of said disk cartridges;
- an indentation configured into said protector to expose said underlying handhold in said disk cartridge;
- a plurality of projections on said protector vertically extending from said protector and juxtapositioned outside said rectangular projection on an adjacent magnetic disk cartridge;
- and
- a vertically extending projection arranged and configured to be disposed in and juxtapositioned next to said handhold in said adjacent magnetic disk cartridge,
- whereby each magnetic disk cartridge is registered and locked with respect to an adjacent one by means of said vertically extending projection and said plurality of projections in combination with said raised rectangular projection of each of said magnetic disk cartridges.
A disked shaped base guard for vertically stacking of magnetic disk cartridges, each having a recessed handhold, comprising:
- resilient retaining means integrally formed with said base guard for temporarily attaching said base guard to said cartridge;
- an indentation configured into said base guard to expose said underlying handhold in said cartridge;
- integral stacking means for registering and locking said cartridge having said base guard attached thereto to another one of said cartridges;
- integral reinforcing means for reinforcing and increasing the rigidity of said base guard;
- wherein said retaining means includes at least three brackets, each bracket being snap fit over one of the edges of said disk cartridge, and
- wherein said stacking means includes a plurality of outwardly disposed projections, each projection mating with a corresponding recess on an adjacent one of said cartridges, said projections including at least four vertically extending projection arranged and configured to be juxtapositioned outside a rectangular raised portion on said adjacent disk cartridge and including a vertically extending projection arranged and configured to be disposed in and juxtapositioned next to said recessed handhold.
A protector for use in horizontally stacking magnetic disk cartridges having a raised rectangular portion on an upper surface thereof and having a recessed handhold said protector including
- a plurality of projections on said protector vertically extending from said protector and juxtapositioned to be outside said rectangular portion on an adjacent disk cartridge;
- and
- a vertically extending projection arranged and configured to be disposed in and juxtapositioned next to said recessed handhold in said adjacent disk cartridge.
A protector for use in horizontally stacking a plurality of magnetic disk cartridges having a handhold comprising:
- resilient means for removably attaching said protector to one of said disk cartridges;
- an indentation configured into said protector to expose said underlying handhold in said disk cartridge;
- stacking means for registering and locking said disk cartridge attached to said protector, said registration being with respect to a vertically adjacent disk cartridge;
- wherein said protector attaches to the lower surface of said disk cartridge, wherein said stacking means includes a plurality of outwardly extending integral projections from said protector, each said projection arranged and configured to be disposed in a corresponding recess of the upper surface of an adjacent one of said plurality of disk cartridges, wherein said disk cartridge has a raised rectangular portion on its upper surface terminating in a portion of said recessed handhold at one end of said rectangular portion, and wherein said plurality of projections on said protector includes at least four vertically extending projections arranged and configured to be juxtapositioned outside said rectangular portion on said adjacent disk cartridge and includes a vertically extending projection arranged and configured to be disposed in and juxtapositioned next to said recess.
