Latch mechanism for notebook security lock

摘要

The present invention provides a latch mechanism 10 for a notebook security lock. The latch mechanism 10 has a cylindrical body 20 having an open end 22 adapted for receiving a lock 60 and a closed end 24 having a slot 26 defined therein. The lock 60 may be any cylindrical lock having an axially slidable lock bar 62, and may be a push button tubular lock. The latch mechanism 10 includes a frustoconical cam 68 adapted for attachment to the end of the lock bar 62. A pair of elongated scissor-type levers 72 are pivotally mounted with resiliently biased head portions disposed within the body 20 and distal hook portions 80 extending from the slot 26. The levers 72 are resiliently biased toward an unlocked position in which the hooks 80 overlap for insertion through a rectangular slot 14 in the sidewall of a notebook computer 12, and in a locked position the levers 72, and thereby the hooks 80, are spread apart by the axial extension of the lock bar 62 and cam 68 in order to latch the hooks 80 behind the sidewall.
