Abstract

A hinge assembly for pivotally coupling a door to a telecommunications chassis includes a hinge structure configured to attach the door to the telecommunications chassis, the hinge structure defining a door pivot point and a hinge pivot point that is spaced from the door pivot point, wherein a door coupled by the hinge structure to the telecommunications chassis can pivot with respect to the hinge structure independent of a pivoting motion of the hinge structure with respect to the telecommunications chassis, wherein the hinge structure further defines at least a portion of a pivot limiting structure spaced from the hinge pivot point, the portion of the pivot limiting structure defined by the hinge structure being configured to interact with the telecommunications chassis in limiting the pivoting motion of the hinge structure.

First claim

The invention claimed is:

1. A hinge assembly for pivotally coupling a door to a telecommunications chassis, the hinge assembly comprising:
a unitarily-formed one-piece hinge structure configured to attach the door to the telecommunications chassis, the hinge structure defining a door pivot point and a hinge pivot point that is spaced at a fixed distance from the door pivot point such that the distance between the door pivot point, where a door coupled by the hinge structure to the telecommunications chassis pivots relative to the hinge structure, and the hinge pivot point, where the hinge structure pivots relative to the telecommunications chassis, does not change, wherein the door coupled by the hinge structure to the telecommunications chassis can pivot with respect to the hinge structure independent of a pivoting motion of the hinge structure with respect to the telecommunications chassis,
wherein the hinge structure further defines at least a portion of a pivot limiting structure spaced from the hinge pivot point, the portion of the pivot limiting structure defined by the hinge structure being configured to interact with the telecommunications chassis in limiting the pivoting motion of the hinge structure, wherein the pivot limiting structure is defined by a slot formed on the hinge structure that is spaced from the hinge pivot point and that is also separate from and spaced from the door pivot point, wherein the slot defining the pivot limiting structure is configured to interact with a pin defined on the telecommunications chassis to limit the pivoting motion of the hinge structure, and
wherein the hinge structure is configured such that when the door is at a fully closed position with respect to the telecommunications chassis, the door pivot point of the hinge structure is configured so as to be positioned forward of a vertical front face panel of the door, and when the door is at a fully open position with respect to the telecommunications chassis, the door pivot point of the hinge structure is configured so as to be positioned rearward of the vertical front face panel of the door.

2. The hinge assembly of claim 1 , further comprising a fastener for removable mounting to the telecommunications chassis for keeping the hinge structure coupled to the chassis without interfering with the pivotal motion of the hinge structure.

3. The hinge assembly of claim 1 , wherein the hinge structure defines a wall configured to be contacted by the door when bringing the door from the open position toward the closed position so as to start the pivoting motion of the hinge structure in a closing direction.

4. The hinge assembly of claim 1 , wherein the hinge structure defines a cut-out configured to accommodate a similar door that is below the door coupled by the hinge structure when the door coupled by the hinge structure is in an open position.

5. The hinge assembly of claim 1 , wherein at least a portion of the hinge structure defines a curved configuration to provide edge protection for optical fibers.

6. A telecommunications system comprising:
a telecommunications chassis; and
a door pivotally attached to the telecommunications chassis via a hinge assembly, the hinge assembly further comprising:
a unitarily-formed one-piece hinge structure extending between the telecommunications chassis and the door, the hinge structure defining a door pivot point and a hinge pivot point that is spaced at a fixed distance from the door pivot point such that the distance between the door pivot point, where the door coupled by the hinge assembly to the telecommunications chassis pivots relative to the hinge structure, and the hinge pivot point, where the hinge structure pivots relative to the telecommunications chassis, does not change, wherein the door coupled by the hinge assembly to the telecommunications chassis can pivot with respect to the hinge structure independent of a pivoting motion of the hinge structure with respect to the telecommunications chassis,
wherein the hinge structure further defines at least a portion of a pivot limiting structure spaced from the hinge pivot point, the portion of the pivot limiting structure defined by the hinge structure being configured to interact with the telecommunications chassis in limiting the pivoting motion of the hinge structure, wherein the pivot limiting structure is defined by a slot formed on the hinge structure that is spaced from the hinge pivot point and that is also separate from and spaced from the door pivot point, wherein the slot defining the pivot limiting structure is configured to interact with a pin defined on the telecommunications chassis to limit the pivoting motion of the hinge structure, and
wherein the hinge structure is configured such that when the door is at a fully closed position with respect to the telecommunications chassis, the door pivot point of the hinge structure is positioned forward of a vertical front face panel of the door, and when the door is at a fully open position with respect to the telecommunications chassis, the door pivot point of the hinge structure is positioned rearward of the vertical front face panel of the door.

7. The telecommunications system of claim 6 , wherein the hinge assembly further comprises a fastener removably mounted to the telecommunications chassis for keeping the hinge structure coupled to the chassis without interfering with the pivotal motion of the hinge structure.

8. The telecommunications system of claim 6 , wherein the hinge structure defines a wall configured to be contacted by the door when bringing the door from the open position toward the closed position so as to start the pivoting motion of the hinge structure in a closing direction.

9. The telecommunications system of claim 6 , wherein the hinge structure defines a cut-out configured to accommodate a similar door that is below the door coupled by the hinge structure when the door coupled by the hinge structure is in the open position.

10. The telecommunications system of claim 6 , wherein at least a portion of the hinge structure defines a curved configuration to provide edge protection for optical fibers.
