Laptop Casing Locking Mechanism

   Disclosed is a method of design to improve security for
portable computing devices.  The idea is to incorporate a key lock
and combination lock mechanism into the casing design of portable
computers (laptops/notebooks/thinkpads/etc.).

   The two primary types of locking mechanisms are the key
lock and the combination lock.  By using both types of locks, a
secure laptop casing can be designed (refer to the Figure).  To set
the combination lock, one inserts the key into the key hole and turns
clockwise (the key now can not be removed from the key hole).  This
disables the combination locks and allows the owner to set the
numbers.  After one turns the keycounter-clockwise back to the
initial position and removes the key, the combination lock is set.
When the combination lock is not turned to the preset numbers, the
latch is disabled and will not allow the laptop case to open.
Metallic metal rods and clamps secure the casing together.  The key
can also serve as the primary locking mechanism by inserting it,
turning it counter-clockwise and then removing the key.  This locks
the casing together until the key is re-inserted and turned clockwise
back to the initial position.
