  • Personal computer security apparatus with lockable slides engaging removable cover
    Patent number: 5446618
    Abstract: A computer with a removable cartridge type hard disk drive (14) or other removable device includes a three position slider 26. At one end of the slider is a tab (20A) having a hole (20B) for receiving a lock. When the slider is in a first position, the tab is retracted within the computer housing (2) and the disk drive can be easily removed from the computer. When the slider is in a second position, the tab protrudes from the housing and the disk drive cannot be removed from the computer. In the second position and with the tab protruding from the housing, a padlock can be inserted into the hole in the tab to secure the slider in the second position, thereby locking the disk drive in the computer. When the slider is in the third position, the tab does not protrude from the housing, but the disk drive cannot be removed from the computer.
