Abstract

This invention is a wireless communication device (100) that includes a housing (102) and a compartment (202) accessible from one side of the housing. The device also includes a compartment cover (212) that has a covering position over the compartment and a latching assembly (214) that is supported by the housing. The latching assembly is capable of receiving an end portion (216) of the compartment cover such that the latching assembly requires less interactive force to receive the end portion than to release the end portion. In addition, the latching assembly includes an inner component (404) positioned adjacent to the housing and an outer component (402) positioned adjacent to the inner component. The inner component moves together with the outer component to release the end portion of the compartment cover and moves separate from the outer component to receive the end portion of the compartment cover.

Claims

1. A wireless communication device comprising:

a housing having a compartment accessible from at least one side of said housing;

a compartment cover including an end portion, said compartment cover having a covering position over said compartment; and

a latching assembly supported by said housing, said latching assembly including an inner component and being effective to receive said end portion of said compartment cover, said latching assembly requiring less interactive force to receive said end portion than to release said end portion,

wherein said end portion of said compartment cover is effective to rotate said inner component when said latching assembly receives said end portion.

2. The wireless communication device of claim 1, wherein said latching assembly includes an inner component, said inner component rotates when said latching assembly receives said end portion of said compartment cover, and said inner component shifts when said latching assembly releases said end portion of said compartment cover.

3. The wireless communication device of claim 2, wherein said inner component rotates at an angle relative to said housing when said latching assembly receives said end portion of said compartment cover.

4. The wireless communication device of claim 2, wherein said inner component shifts in a parallel direction relative to said housing when said latching assembly releases said end portion of said compartment cover.

5. The wireless communication device of claim 1, wherein said latching assembly includes a spring mechanism for biasing said latching assembly away from said housing.

6. The wireless communication device of claim 5, wherein said spring mechanism is subjected to a partial compression when said latching assembly receives said end portion of said compartment cover.

7. The wireless communication device of claim 6, wherein said spring mechanism is subjected to a substantial compression when said latching assembly releases said end portion of said compartment cover, and said substantial compression is greater than said partial compression.

8. The wireless communication device of claim 5, wherein:

said latching assembly includes an inner component, said spring mechanism being positioned against said inner component at a contact location;

said inner component directs a first force toward said contact location to releases said end portion of said compartment cover;

said inner component directs a second force toward a location offset from said contact location to receives said end portion of said compartment cover; and

said first force is greater than said second force.

9. The wireless communication device of claim 8, wherein:

said inner component includes at least one protrusion extending from a particular location of said inner component, said particular location being offset from said contact location; and

said end portion of said compartment cover subjects said second force to said at least one protrusion when said latching assembly receives said end portion.

10. The wireless communication device of claim 1, wherein said compartment is capable of receiving a removable module, said removable module being a power source.

11. The wireless communication device of claim 10, further comprising a transceiver circuit positioned in said housing, said power source being effective to provide electrical power to said transceiver circuit.

12. A wireless communication device comprising:

a housing having a compartment accessible from at least one side of said housing;

a compartment cover including an end portion, said compartment cover having a covering position over said compartment; and

an inner component positioned adjacent to said housing and an outer component positioned adjacent to said inner component, said inner component being effective to move together with said outer component to release said end portion of said compartment cover and move separate from said outer component to receive said end portion of said compartment cover, said inner component requiring less interactive force to receive said end portion than to release said end portion.

13. The wireless communication device of claim 12, wherein said end portion of said compartment cover is effective to rotate said inner component to receive said end portion.

14. The wireless communication device of claim 12, wherein said inner component rotates to receive said end portion of said compartment cover, and said inner component shifts to release said end portion of said compartment cover.

15. The wireless communication device of claim 14, wherein said inner component rotates separate from said outer component when said inner component receives said end portion of said compartment cover.

16. The wireless communication device of claim 14, wherein said inner component shifts together with said outer component when said inner component releases said end portion of said compartment cover.

17. The wireless communication device of claim 12, further comprising a spring mechanism for biasing said inner component away from said housing.

18. The wireless communication device of claim 17, wherein said spring mechanism is subjected to a partial compression when said inner component receives said end portion of said compartment cover.

19. The wireless communication device of claim 18, wherein said spring mechanism is subjected to a substantial compression when said inner component releases said end portion of said compartment cover, and said substantial compression is greater than said partial compression.

20. The wireless communication device of claim 17, wherein:

said spring mechanism is positioned against a contact location of said inner component;

said inner component and said outer component direct a first force toward said contact location to releases said end portion of said compartment cover;

said inner component directs a second force toward a location offset from said contact location to receives said end portion of said compartment cover; and

said first force is greater than said second force.

21. The wireless communication device of claim 20, wherein

said inner component includes at least one protrusion extending from a particular location of said inner component, said particular location being offset from said contact location;

and

said end portion of said compartment cover subjects said second force to said at least one protrusion when said inner component receives said end portion.

22. The wireless communication device of claim 12, wherein said compartment is capable of receiving a removable module, said removable module being a power source.

23. The wireless communication device of claim 12, further comprising a transceiver circuit positioned in said housing, said power source being effective to provide electrical power to said transceiver circuit.
