摘要

The cover of an item of equipment such as an audio system is secured with a latch mechanism. The latch has a main housing (14) with a internal spring (40) supported on a post (42) and a follower arm (3) that is captive at one (BB) and engages in a guide track (48) at the other. The guide track is formed in an interlock element (30) and this has a heart shaped profile (48) at the centre. A pushbutton actuator displaces the interlock to latch the end (13A) of the follower against the heart shaped protector. When the actuator is pressed again the follower is released. ADVANTAGE - Simple and reliable latching device.
