Abstract
A pair of plates that are inserted into the disk drive of a computer. The plates are then locked together by the addition of a padlock or other locking means thus preventing disk drive use and removal of the plates. The plates and computer can be secured to a fixed object with an anti-theft means or cable system in combination with the padlock to prevent the computer from being stolen or removed from a fixed location.
Claims25
A locking mechanism for a computer with a disk drive having an external entry door and internal guide rails with tab holes, comprising:
- a rigid first plate adapted for insertion into said disk dive and having a front edge, a back edge, two side edges, top and bottom surface planes, a plate shoulder formed on the front edge, and a plate body between the plate shoulder and the back edge, a pair of tabs extending in the downward direction from the bottom surface plane of the first plate body and adapted for insertion into said guide rail tab holes, and a lock hole formed centrally in the plate shoulder;
- a rigid second plate adapted for insertion into said disk drive and having a front edge, a back edge, two side edges, top and bottom surface planes, a plate shoulder formed on the front edge, and a plate body between the plate shoulder and the back edge, a pair of ridges extending in an upward direction away from the top surface plane of the second plate body, and a lock hole formed centrally in the plate shoulder;
- wherein said second plate is inserted into said disk onto the top surface plane of the first plate such that the second plate bottom surface plane lies flat against the first plate top surface plane;
- wherein said first and second plate lock holes align when both plates are inserted into said disk drive;
- a locking means for securing said lock holes of said inserted first and second plates;
- and
- means for tethering said locking means to an object;
- wherein the combined height of the first and second plates inserted together into the disk drive together is such that the plates cannot be removed from the disk drive together;
- wherein said first and second plate shoulder portions and lock holes are adapted to remain outside the disk drive when inserted into the disk drive;
- wherein the second plate ridges extend from the plate shoulder toward the back edge parallel to one another and parallel to the second plate right and left edges;
- and
- wherein said first plate tabs angle away from the first plate bottom surface plane at an angle of approximately seventy degrees from a plane defined by the area between the tabs and the front edge of the first plate.
