Abstract
An indexing hinge comprises a two arm hinge half and an axle hinge half. The two arm hinge half includes two hinge arms, a projecting indexing element disposed therebetween and a first mounting element. The axle hinge half includes two axles, each extending from a toothed indexing element, and a second mounting element. When the axle hinge half is connected to the two arm hinge half by interconnecting each axle with a respective hinge arm, the projecting indexing element abuts the toothed indexing element in such a way as to prevent rotation unless an additional rotational torque is applied. An electronic equipment enclosure installation comprises an electronic equipment enclosure and an indexing hinge.
Claims23
An electronic equipment enclosure installation, comprising
- (a) an electronic equipment enclosure, including a first structure and a second structure, at least one of which is a door structure against which air is directed, and
- (b) an indexing hinge rotatably supporting the door structure, comprising:
- (i) a two arm hinge half, including two hinge arms, a projecting indexing element disposed therebetween, and a first mounting element adapted to mount and connect the two arm hinge half to the first structure of the electronic equipment enclosure;
- and
- (ii) an axle hinge half, including two axles, each extending from a toothed indexing element, and a second mounting element adapted to mount and connect the axle hinge half to the second structure of the electronic equipment enclosure;
- (iii) wherein when the axle hinge half is connected to the two arm hinge half by interconnecting each axle with a respective hinge arm, the projecting indexing element abuts the toothed indexing element in such a way as to prevent rotation of the door structure, when air is directed against the door structure, unless an additional rotational torque is applied;
- (c) wherein the door structure may be selectively positioned to control the flow of air in the electronic equipment enclosure;
- and
- (d) wherein the door structure and the indexing hinge are both entirely disposed within an interior of the electronic equipment enclosure.

A passive air control device indexing hinge, comprising:
- (a) a two arm hinge half, including two hinge arms, a projecting indexing element disposed therebetween, and a first mounting element adapted to mount and connect the two arm hinge half to a first structure;
- and
- (b) an axle hinge half, including two axles, each extending from a toothed indexing element, and a second mounting element adapted to mount and connect the axle hinge half to a second structure;
- (c) wherein at least one of the first and second structures is a panel adapted to redirect air toward the other of the first and second structures when the air is directed toward the panel;
- (d) wherein when the axle hinge half is connected to the two arm hinge half by interconnecting each axle with a respective hinge arm, the projecting indexing element abuts the toothed indexing element in such a way as to prevent rotation and enable selective positioning resistant to the flowing air unless an additional rotational torque is applied by user;
- (e) wherein the two arm hinge half, the axle hinge half, and the first and second structures are all entirely disposed within an interior of an electronic equipment enclosure;
- and
- (f) wherein the at least one of the first and second structures that is a panel adapted to redirect air toward the other of the first and second structures is adapted to redirect air flowing through the interior of the electronic equipment enclosure.

- (c) wherein the door structure may be selectively positioned to control the flow of air in the electronic equipment enclosure;
- (d) wherein the door structure and the indexing hinge are both entirely disposed within an interior of the electronic equipment enclosure;
- (e) wherein the indexing hinge is configured such that, when the two arm hinge half is mounted to the first structure of the electronic equipment enclosure and the axle hinge half is mounted to the second structure of the electronic equipment enclosure, the first structure is rotatable relative to the second structure.
