ABSTRACT:
The specification discloses a furniture system in which a furniture unit is hung on a support by means of hooks which hook into apertures in the support, the unit being locked in place by a lock which is biased into engagement with one of the apertures in the support. The lock and furniture unit in which it is mounted include a detent system which holds the lock in an unlocked position when engaged, enabling one to remove the furniture unit from the support without having to simultaneously manually hold the lock in an unlocked position. The lock and the support further include an automatic release system which automatically releases the detent when the unit is first hooked into the support whereby the lock automatically snaps into its locked condition.
