Abstract

A fiber optic organizer includes a mounting bracket and a plurality of organizer trays having proximal and distal ends. The organizer trays are pivotally connected at their proximal ends to the mounting bracket and are movable between a stacked position and a raised position to facilitate access to an underlying organizer tray. A locking mechanism is positioned on the distal end of each tray and locks at least two adjacent organizer trays together in a raised position when the organizer trays are lifted to a predetermined angle, and disengages the locked organizer trays when the organizer trays are lifted beyond the predetermined angle. The locking mechanism on each organizer tray includes a slot and an upstanding tab that is received within a slot on an overlying organizer tray when the organizer trays are raised to a predetermined angle. The tab and slot can be angled to assist in pushing an overlying organizer tray into its raised position and also assist in retaining the organizer trays in a locked position if the locked organizer trays are jarred. When raised beyond the predetermined angle, the organizer trays can separate from each other. As the organizer trays are lowered into the stacked position, the organizer trays are maintained separate from each other.

13. The fiber optic organizer according to claim 1 wherein said organizer trays are generally rectangular.

14. The fiber optic organizer according to claim 1 wherein said organizer trays are generally oval.

15. The fiber optic organizer according to claim 1 including a housing for supporting said mounting bracket and organizer trays.

16. The fiber optic-organizer according to claim 15 wherein said housing forms a sealed chamber.

17. The fiber optic organizer according to claim 15 wherein said housing is generally rectangular.

18. The fiber optic organizer according to claim 15 wherein said housing includes means for mounting to an equipment rack.

19. The fiber optic organizer according to claim 1 wherein each of said organizer trays includes guides to retain a fiber optic cable to the organizer tray.

20. The fiber optic organizer according to claim 1 wherein each of said organizer trays includes at least one strain relief grommet.

21. A fiber optic organizer comprising

a mounting bracket;

a plurality of organizer trays, each organizer tray having proximal and distal ends and pivotally connected at the proximal end to the mounting bracket to be movable between a stacked position and a raised position to facilitate access to an underlying organizer tray; and

locking means positioned on the distal end of each organizer tray for locking at least two organizer trays together in the raised position when the organizer trays are lifted to a predetermined angle to facilitate access to the underlying organizer tray and for disengaging the organizer trays when the organizer trays are lifted beyond the predetermined angle.

22. The fiber optic organizer, according to claim 21, including means pivotally mounting the organizer trays offset to each other so that the raised organizer trays are separated from each other when the trays are raised beyond the predetermined angle.

23. The fiber optic organizer according to claim 21 wherein said locking means comprises a slot on an overlying organizer tray and an upstanding tab on an underlying organizer tray that is received within the slot when the organizer trays are raised.

24. The fiber optic organizer according to claim 23 wherein each upstanding tab includes an end having a protrusion for engaging the organizer tray when the tab is received within the slot.

25. The fiber optic organizer according to claim 23 wherein said tab engages the slot in the overlying organizer tray when the organizer trays are raised to a predetermined angle.

26. The fiber optic organizer according to claim 23 wherein said tab disengages from the slot when the organizer trays are raised beyond a predetermined angle.

27. The fiber optic organizer according to claim 23 wherein the distal ends of said organizer trays are offset so that an organizer tray is raised to a predetermined angle, the tab in an underlying organizer tray is received within the slot on the overlying organizer tray.

28. The fiber optic organizer according to claim 23 wherein said organizer trays are generally rectangular.

29. The fiber optic organizer according to claim 23 wherein said organizer trays are generally oval.
