Abstract

A fitting for a vent stringer of a type having an open end and an outer edge defining the open end. The fitting may include a fitting body receivable along the open end of the vent stringer, the fitting body having a groove that generally corresponds with the outer edge of the vent stringer, the groove of the fitting body shaped to receive the outer edge of the vent stringer to create a tongue and groove joint with the outer edge; and a connection between the fitting and the stringer to prevent slidable movement of the fitting relative to the stringer.

First claim

What is claimed is:

1. A fitting for a vent stringer, the vent stringer having a channel, an open end and an outer edge defining the open end, the fitting comprising:
a fitting body receivable along the open end of the vent stringer, the fitting body defining:
a groove that generally corresponds with a portion of the outer edge of the vent stringer, the groove of the fitting body shaped to receive the portion of the outer edge of the vent stringer to create a tongue and groove joint with the portion of the outer edge of the vent stringer;
a pair of opposing side walls and a base wall that each extend around a portion of the open end of the vent stringer, wherein the pair of opposing side walls and the base wall extend into the channel of the vent stringer to create a seal with a portion of the open end of the vent stringer; and
a connection between the fitting and the stringer to prevent slidable movement of the fitting relative to the stringer.

2. The fitting of claim 1 , wherein the fitting body defines a mating edge located within the groove.

3. The fitting of claim 2 , wherein the mating edge of the fitting body abuts the outer edge of the vent stringer.

4. The fitting of claim 2 , further comprising a sealant interposed between the mating edge of the fitting body and the outer edge of the vent stringer.

5. The fitting of claim 1 , wherein the fitting further comprises a lip, and wherein the lip is configured to extend into the channel of the vent stringer.

6. The fitting of claim 1 , wherein the fitting further comprises a coupling configured to fluidly connect the channel of the vent stringer with a vent tube.

7. The fitting of claim 1 , wherein the fitting body is constructed of a composite material.

8. An aircraft comprising:
a vent stringer having a channel, an open end and an outer edge located at the open end; and
a fitting having
a fitting body receivable along the open end of the vent stringer, the fitting body defining a groove that generally corresponds with a portion of the outer edge of the vent stringer, the groove of the fitting body shaped to receive the portion of the outer edge of the vent stringer to create a tongue and groove joint with the portion of the outer edge of the vent stringer,
a pair of opposing side walls and a base wall that each extend around a portion of the open end of the vent stringer, wherein the pair of opposing side walls and the base wall extend into the channel of the vent stringer to create a seal with a portion of the open end of the vent stringer; and
a connection between the fitting and the stringer to prevent slidable movement of the fitting relative to the stringer.

9. The fitting of claim 8 , wherein the fitting body defines a mating edge located within the groove.

10. The fitting of claim 9 , wherein the mating edge of the fitting body abuts the outer edge of the vent stringer.

11. The fitting of claim 9 , further comprising a sealant interposed between the mating edge of the fitting body and the outer edge of the vent stringer.

12. The fitting of claim 8 , wherein the fitting further comprises a lip, and wherein the lip is configured to extend into the channel of the vent stringer.

13. The fitting of claim 8 , wherein the fitting further comprises a coupling configured to fluidly connect the channel of the vent stringer with a vent tube.

14. A method of installing a fitting to a vent stringer, the vent stringer having a channel, an open end and an outer edge located at the open end, the method comprising:
sliding the fitting in a longitudinal direction along the vent stringer, wherein the fitting defines a groove that generally corresponds with the outer edge of the vent stringer;
receiving a portion of the outer edge of the vent stringer by the groove of the fitting body, wherein the groove of the fitting body is shaped to receive the outer edge of the vent stringer to create a tongue and groove joint with the portion of the outer edge of the vent stringer;
creating a seal between a pair of opposing side walls and a base wall of the fitting and a portion of the open end of the vent stringer, wherein the pair of opposing side walls and the base wall extend into the channel of the vent stringer to create a seal with the portion of the open end of the vent stringer; and
providing a connection between the fitting and the stringer to prevent further slidable movement of the fitting relative to the stringer.

15. The method of claim 14 , further comprising coupling a vent tube to the fitting.

16. The method of claim 14 , wherein providing a connection between the fitting and the stringer includes one or both of providing a positive mechanical connection between the fitting and the stringer, and providing a sealant between the fitting body and the stringer.
