Abstract

An electronic device sealing arrangement includes a housing, an access door, a sealing member sized and configured to be sealingly compressed between the access door and the housing, a latch in operable communication with the housing and the access door, the latch being configured to compress the sealing member between the access door and the housing when moved to a position that latches the access door in a closed position, and a resilient member in operable communication with the latch and at least one of the housing and the access door, the resilient member being configured to at least partially compress when the access door is latched in the closed position and the sealing member is compressed between the access door and the housing.

First claim

What is claimed is:

1. An electronic device sealing arrangement, comprising:
a housing;
an access door;
a sealing member sized and configured to be compressed between the access door and the housing;
a latch with a bore in operable communication with the housing and the access door, the latch being configured to compress the sealing member between the access door and the housing when moved to a position that latches the access door in a closed position; and
a resilient member in operable communication with the latch and at least one of the housing and the access door, the resilient member being configured to at least partially compress when the access door is latched in the closed position and the sealing member is compressed between the access door and the housing
wherein the resilient member includes a pair of resilient members abutting the bore,
wherein the pair of resilient members includes a pair of polymeric inserts configured to deflect laterally upon closing of the latch.

2. The electronic device of claim 1 , wherein the sealing member forms a face seal between a surface on an access area and the access door upon closing of the access door.

3. The electronic device of claim 1 , wherein deflection of at least one of the pair of resilient members increases an amount of allowable lateral movement of the latch.

4. The electronic device of claim 1 , wherein an access area includes one of a battery compartment, a memory access compartment and an input/output compartment.

5. The electronic device of claim 1 , wherein the electronic device includes a camera.

6. The electronic device of claim 1 , wherein:
the bore is configured for receiving a hinge pin, the latch being configured to pivot about the hinge pin;
the resilient member is configured adjacent to the bore to accommodate lateral movement of the hinge pin in the bore;
the latch includes an arm portion configured to slidably engage a groove on the electronic device to toggle the user access door between a locked position and an unlocked position; and
the resilient member, in the locked position, relieves the overall compression on the sealing member of the user access door in a closed position.

7. The electronic device of claim 6 , wherein the arm portion is disengaged from the groove in the unlocked position.

8. The electronic device of claim 6 , wherein the arm portion is engaged with the groove in the locked position.

9. The electronic device of claim 1 , wherein at least one of the pair of resilient members includes a compressible material.

10. The electronic device of claim 9 , wherein at least one of the pair of resilient member includes a polymeric insert.

11. The electronic device of claim 10 , wherein the polymeric insert is selected to match an overall compression of the sealing member.

12. The electronic device of claim 10 , wherein compressibility of the polymeric insert is inversely related to compressibility of the sealing member.

13. A latch assembly, comprising:
a latch in operable communication with a housing and an access door of an electronic device, the latch being configured to compress the sealing member between the access door and the housing when moved to a position that latches the access door in a closed position; and
a resilient member in operable communication with the latch and at least one of the housing and the access door, the resilient member being configured to at least partially compress when the access door is latched in the closed position and the sealing member is compressed between the access door and the housing,
wherein the resilient member includes a pair of resilient members abutting the bore,
wherein the pair of resilient members includes a pair of polymeric inserts configured to deflect laterally upon closing of the latch.

14. The latch assembly of claim 13 , wherein the latch includes a bore configured for receiving a hinge pin, the latch being configured to pivot about the hinge pin, and the resilient member being configured to be adjacent to the bore to accommodate lateral movement of the hinge pin in the bore.

15. The latch assembly of claim 13 , wherein the resilient member is configured to deflect laterally upon closing of the latch.

16. A method of sealing an electronic device, comprising:
rotating an access door about a pivot defined in a housing;
moving a latch relative to the access door and the housing;
compressing a sealing member between the access door and the housing; and
compressing a pair of resilient members between the latch and at least one of the access door and the housing, wherein compressing the resilient member includes deflecting laterally a pair of polymeric inserts included in the pair of resilient members upon moving the latch.
