Abstract

An apparatus for mounting an antenna onto a vehicle including a base assembly and a fastener. The base assembly is removably attached to the vehicle and includes a mounting portion and a housing. The mounting portion includes a main body having at least one arm extending therefrom, a top portion, and at least one engaging element for removably attaching the base assembly to the vehicle. The housing is connected to the base. The fastener has guide structure for engaging at least one arm for securing the base assembly to the vehicle.

Claims

1. An apparatus for mounting an antenna onto a vehicle, comprising:

a base assembly removably attached to the vehicle including a mounting portion and a housing;

the mounting portion including a main body having at least one arm extending from the main body, a top portion, and at least one engaging element for removably attaching the base assembly to the vehicle;

the housing connected to the base assembly; and

,

a fastener having a guide structure for engaging the at least one arm and thereby securing the base assembly to the vehicle.

2. The apparatus as recited in claim 1, wherein the at least one arm includes a pair of arms disposed in opposition on said main body adjacent a free end of said main body.

3. The apparatus as recited in claim 1, wherein the main body further includes an indexing element for correctly orientating the base assembly relative to the vehicle.

4. The apparatus as recited in claim 1, wherein the engaging element includes an arm connected to said main body at a first end and having a structure at a free end of the arm such that the mounting portion snap-fits to the vehicle.

5. The apparatus as recited in claim 4, wherein said first end is adjacent to said top portion such that said arm extends along a longitudinal axis of the main body.

6. The apparatus as recited in claim 1, wherein the guide structure includes a groove formed in an inner surface of the fastener.

7. The apparatus as recited in claim 6, wherein the groove includes a contoured surface having a locking structure formed thereon.

8. The apparatus as recited in claim 7, wherein the locking structure includes an eccentric surface for signaling that the base assembly is secured to the vehicle and preventing over-tightening of the fastener.

9. The apparatus as recited in claim 7, wherein the locking structure further includes a pocket for retaining the arms when the base assembly is secured to the vehicle.

10. The apparatus as recited in claim 1, wherein a quarter-turn of the fastener secures the base assembly to the vehicle.

11. An apparatus for mounting an antenna onto a vehicle, comprising:

a base assembly and a nut;

the base assembly includes a mounting portion and a housing;

the mounting portion includes a cylindrical main body having a pair of arms extending in opposition, an enlarged top portion separated from the main body by a shoulder, and an engaging element for removably connecting the base assembly to the vehicle;

the housing connected to the top portion; and

,

the nut including a groove formed in an inner surface of the nut having a contoured surface for securing the base assembly to the vehicle.

12. The apparatus as recited in claim 11, wherein the arms are disposed adjacent a free end of the main body.

13. The apparatus as recited in claim 11, wherein the main body further includes an indexing element for correctly orientating the base assembly relative to the vehicle.

14. The apparatus as recited in claim 13, wherein the indexing element is formed as a longitudinally extending groove.

15. The apparatus as recited in claim 11, wherein the engaging element includes a deflectable arm connected to the main body at a first end adjacent the shoulder end and a structure disposed on a free end of the arm so that the mounting portion snap-fits to the vehicle.

16. The apparatus as recited in claim 11, wherein the base assembly is secured to the vehicle by a quarter turn of the nut.

17. The apparatus as recited in claim 11, wherein the contoured surface includes an over-center locking structure.

18. An apparatus for mounting an antenna onto a vehicle, comprising:

a base assembly and nut;

the base assembly including a mounting portion, a dielectric insert, a housing, and a threaded insert;

the mounting portion including a cylindrical main body having a pair of arms extending in opposition disposed at a free end of the main body, an indexing element, and an enlarged top portion having a centrally disposed aperture in communication with a bore extending through the mounting portion;

the dielectric insert received and retained within the aperture and bore;

the housing connected to the mounting portion and including a centrally disposed aperture axially aligned with the main body aperture and bore for receiving and retaining the threaded insert;

the threaded insert including a first end for engaging the antenna and a second end which projects through the dielectric insert adapted for connection with an antenna circuit; and

,

the nut including a guide structure having a contoured surface for engaging the arms and securing the base assembly to the vehicle.

19. The apparatus as recited in claim 18, wherein the contoured surface includes an over-center locking structure.

20. The apparatus as recited in the claim 18, wherein the base assembly is secured to the vehicle by a quarter turn of the locking nut.
