Abstract

A method and apparatus is provided for adjusting a latch. An apparatus comprises a latch body, a first member, and a second member associated with the latch body. A receiving area extends through at least a portion of the latch body. The first member is configured to be at least partially received within the receiving area of the latch body. The first member has a first coupling element. The second member has a second coupling element. Movement of the first member along an axis through the receiving area changes a distance between the first coupling element and the second coupling element.

First claim

What is claimed is:

1. An apparatus comprising:
a latch body, wherein a receiving area extends through at least a portion of the latch body;
a first member configured to be at least partially received within the receiving area of the latch body, wherein the first member has a first coupling element;
a second member associated with the latch body, wherein the second member has a second coupling element and wherein movement of the first member along an axis through the receiving area changes a distance between the first coupling element and the second coupling element;
a third member associated with the latch body, wherein the third member has a third coupling element;
an adjustment member wherein relative rotation between the adjustment member and the first member causes the first member to move along the axis; and
a pivotable element, wherein the pivotable element is movable independent of the adjustment member and wherein rotation of the pivotable element into a locked position locks the adjustment member in place to prevent the relative rotation between the adjustment member and the first member and wherein rotation of the pivotable element into an unlocked position unlocks the adjustment member to allow the relative rotation between the adjustment member and the first member.

2. The apparatus of claim 1 wherein the first and second coupling elements are cylindrical.

3. The apparatus of claim 1 , wherein the wherein the second coupling element is configured to allow the second attachment structure to move along the axis.

4. The apparatus of claim 1 , wherein the third coupling element is configured to be connected to a structural member of an aerospace vehicle.

5. The apparatus of claim 4 , wherein the first coupling element is configured to be connected to a first panel and the second coupling element is configured to be connected to a second panel.

6. The apparatus of claim 1 , wherein the adjustment member comprises:
a plurality of grooves, wherein the pivotable element is configured to enter a groove in the plurality of grooves when the pivotable element is in the locked position.

7. The apparatus of claim 1 , wherein the first member comprises:
a protrusion configured to enter an open end of a control area within the latch body when the first member enters the receiving area within the latch body, wherein the control area is a slot and has a closed end.

8. The apparatus of claim 7 further comprising:
a cap configured for association with the latch body, wherein the cap is used to close the open end of the control area with the protrusion of the first member located within the control area such that a distance by which the first member can be moved along the axis is determined by a length of the control area.

9. The apparatus of claim 1 , wherein the first coupling element is a first elongated portion of the first member configured to receive a first hook and the second coupling element is a second elongated portion of the second member configured to receive a second hook.

10. The apparatus of claim 1 , wherein a first attachment structure is configured to engage the first coupling element of the first member and a second attachment structure is configured to engage the second coupling element of the second member.

11. The apparatus of claim 10 , wherein the first attachment structure comprises a first hook configured to engage the first coupling element of the first member and the second attachment structure comprises a second hook configured to engage the second coupling element of the second member.

12. The apparatus of claim 10 , wherein the first attachment structure is associated with a first panel and wherein the second attachment structure is associated with a second panel.

13. The apparatus of claim 10 , the second coupling element is configured to allow the second attachment structure to move along the axis.

14. The apparatus of claim 12 , wherein the first panel and the second panel are configured for use in forming a sidewall for an interior of an aircraft.

15. The apparatus of claim 12 , wherein moving the first member along the axis through the receiving area such that a distance between the first coupling element and the second coupling element changes a width of a gap between the first panel and the second panel.

16. The apparatus of claim 12 , wherein the latch body is configured for attachment to a structural member such that the first panel and the second panel are associated with the structural member.

17. A method for using a latch, the method comprising:
inserting a first member having a first coupling element at least partially through a receiving area that extends through at least a portion of a latch body of the latch, wherein the latch comprises a second member associated with the latch body having a second coupling element and a third member associated with the latch body having a third coupling element;
moving the first member along an axis through the receiving area such that a distance between the first coupling element and the second coupling element associated with the latch body changes;
rotating the first member relative to an adjustment member that forms a portion of the receiving area to move the first member along the axis through the receiving area such that the distance between the first coupling element and the second coupling element of the second member associated with the latch body changes; and
pivoting a pivotable element, wherein the pivotable element is movable independent of the adjustment member and wherein rotation of the pivotable element into a locked position locks the adjustment member in place to prevent the relative rotation between the adjustment member and the first member and wherein rotation of the pivotable element into an unlocked position unlocks the adjustment member to allow the relative rotation between the adjustment member and the first member.

18. The method of claim 17 further comprising:
engaging the first coupling element of the first member with a first attachment structure associated with a first panel; and
engaging the second coupling element of the second member with a second attachment structure associated with a second panel.

19. The method of claim 18 , wherein moving the first member along the axis through the receiving area comprises:
moving the first member along the axis through the receiving area to change the distance between the first coupling element and the second coupling element such that a width of a gap between the first panel and the second panel changes.

20. The method of claim 19 , further comprising:
attaching the third coupling element to a structural member of an aircraft.
