Rotary locking apparatus for fiber optic equipment trays and related methods
First Claim
1. A locking apparatus for a fiber optic apparatus, comprising:
- a rod having at least one protrusion configured to selectively engage one or more of a plurality of slots in a tray guide disposed on a chassis; and
a torsion spring configured to attach to the rod and to a tray mounted on a fiber optic equipment tray disposed in the chassis along a first direction parallel to a longitudinal axis of the rod, and further configured to lock the fiber optic equipment tray in a closed position when the at least one protrusion engages a first one of the plurality of slots in the tray guide.

Abstract
A rotary locking apparatus for locking and unlocking a fiber optic equipment tray and related methods are disclosed. The rotary locking apparatus may be a torsional rotary locking apparatus. The torsional rotary locking apparatus includes a rod having at least one protrusion and a torsion spring attached to the rod. The torsion spring may also be attached to a tray mount on the fiber optic equipment tray. The rod can be rotatably actuated such that the at least one protrusion selectively engages or disengages one or more of a plurality of slots in a tray guide to allow the fiber optic equipment tray to move from a closed to an open position. The torsion spring may be configured to lock the fiber optic equipment tray in either the open or the closed position when the at least one protrusion engages one of the plurality of slots in the tray guide.
