Abstract

A stowage container including a barrier such as a door or access panel and a breach detector for monitoring and/or detecting a breach of the barrier. The breach detector includes an indicator assembly having a slot that can be positioned between, and defined by, a front panel and a back panel of the barrier, and an indicator within the slot. The indicator assembly further includes a retainer that maintains the indicator in a first state when the barrier is in a first position (e.g., closed or sealed) and which releases the indicator into a second state when the barrier moves from the first position to a second position (e.g., open or breached). Upon returning the barrier to the first position, the indicator remains in the second state until the indicator reset to the first state.

First claim

The invention claimed is:

1. A container assembly, comprising:
a housing defining a stowage compartment therein;
a barrier configured to be coupled to the housing, wherein the barrier is configured to move between a first position and a second position; and
an indicator configured to actuate from a first state to a second state in response to the barrier moving from the first position to the second position, wherein the indicator is configured to remain in the second state, regardless of whether the barrier is in the first position or the second position, until the indicator is reset from the second state to the first state.

2. The container assembly of claim 1 , wherein the first position comprises a closed position that does not permit access to the stowage compartment, and wherein the second position comprises an open position that permits access to the stowage compartment.

3. The container assembly of claim 1 , further comprising a joint that couples the barrier to the housing, wherein the joint allows the barrier to move between the first position and the second position.

4. The container assembly of claim 1 , wherein the barrier comprises:
a front panel having a window therein;
a back panel; and
a slot defined between the front panel and the back panel.

5. The container assembly of claim 4 , wherein the back panel is visible through the window when the indicator is in the first state.

6. The container assembly of claim 4 , wherein the indicator is not visible through the window when the indicator is in the first state.

7. The container assembly of claim 4 , further comprising a retainer configured to hold the indicator in the first state, wherein the retainer is configured to release the indicator in response to the barrier moving from the first position to the second position, such that the indicator actuates into the second state, and wherein the indicator is at least partially visible through the window when the indicator is in the second state.

8. The container assembly of claim 7 , wherein the retainer is configured to hold the indicator in the first state using a magnetic force.

9. The container assembly of claim 4 , wherein the slot comprises a slot segment that prevents the indicator from inadvertently actuating from the second state back to the first state when the barrier is moved from the second position back to the first position with greater than a predetermined force.

10. The container assembly of claim 9 , wherein the indicator moves into the slot segment and then back into the window when the barrier is moved from the second position back to the first position with greater than the predetermined force.

11. A container assembly, comprising:
a housing defining a stowage compartment therein;
a barrier configured to be coupled to the housing, wherein the barrier is configured to move between a first position and a second position; and
an indicator assembly configured to actuate from a first state to a second state in response to the barrier moving from the first position to the second position, wherein the indicator assembly is not visible when the indicator assembly is in the first state, and wherein the indicator assembly is at least partially visible when the indicator assembly is in the second state.

12. The container assembly of claim 11 , wherein the first position comprises a closed position that does not permit access to the stowage compartment, and wherein the second position comprises an open position that permits access to the stowage compartment.

13. The container assembly of claim 11 , further comprising a joint that couples the barrier to the housing, wherein the joint allows the barrier to move between the first position and the second position.

14. The container assembly of claim 11 , wherein the indicator assembly is configured to remain in the second state, regardless of whether the barrier is in the first position or the second position, until the indicator assembly is reset from the second state to the first state.

15. The container assembly of claim 11 , wherein the indicator assembly comprises:
an indicator comprising a body and an arm extending from the body; and
a post that is coupled to or integral with the housing.

16. The container assembly of claim 15 , wherein the body hangs from the post by the arm when the indicator assembly is in the first state.

17. The container assembly of claim 16 , wherein the arm slides off of the post, thereby causing the indicator to move downward from the first state to the second state, in response to the barrier moving from the first position to the second position.

18. The container assembly of claim 17 , wherein the barrier comprises:
a front panel having a window therein;
a back panel; and
a slot defined between the front panel and the back panel, wherein the indicator is positioned within the slot.

19. The container assembly of claim 18 , wherein the back panel is visible through the window when the indicator is in the first state.

20. The container assembly of claim 18 , wherein the indicator comprises a magnetic material.
