Security mechanism for expansion unit

Disclosed is a security mechanism for expansion unit for mobile computers.

This mechanism is used to secure notebook computers, they have many types of bottom shapes, with single type of hook and it protects the computers from theft.

Portable information devices, such as notebook computers, and expansion units, such as docking stations or port replicators, usually have locking mechanism to protect from theft. In current locking mechanism design, one locking mechanism supports only one dimension of bottom cover of notebooks, thus computer makers have to prepare various kind of expansion units they have different shape of locking mechanism for various notebook computers. A notebook computer will have many restriction on its cover design to design common expansion unit with existing locking mechanism.

This new locking mechanism is flexible in length and it enables to support different shapes of notebook computers with single design, and its length is fixed when the mechanism if in locking state not to stolen.

Fig-1 and fig-2 shows current locking mechanism design. Both types has fixed length hook, and distance between top cover of expansion unit and bottom cover of notebook computer is fixed. The new locking mechanism has flexible length of hook and its length is optimized automatically when a notebook computer is attached to the expansion unit.
