BACKGROUND AND SUMMARY OF THE DISCLOSURE
The present invention relates to a swivel mounted (i.e., rotatable) antenna system that can be mounted on any mobile equipment item, such as a commercial motor vehicle (CMV) or government motor vehicle (GMV), and requires minimal tooling to mount or remove the swivel mount from the mobile equipment item. Due to the unique nature of the swivel mount, the antenna system can be adjusted manually by an operator positioned, illustratively seated, in the passenger compartment of a vehicle in order for the antenna to maintain alignment with an orbiting satellite to enable satellite communications (SATCOM).
A swivel-mounted antenna can be used to support the communications needs of various civilian and military personnel while they are deployed in support of operations occurring within or outside of the United States. A UHF (Ultra-High Frequency) SATCOM antenna mounted on a tripod can be removed from the tripod, and then mounted externally onto the hood of a vehicle via a mounting interface. The mounting interface should enable the antenna to be manually adjusted for altitude, and manually rotated within 360 degrees of azimuth in order to communicate with a satellite (via line of sight) as the satellite orbits the earth.
The combination of a ground supported tripod and a vehicle supported swivel mount apparatus would enable a SATCOM antenna to be used in a dual use capacity. The antenna could be mounted on a tripod that is stationary on the ground, and also could be quickly connected to or disconnected from the tripod depending on the operational need for the antenna. The dual use functionality would allow the antenna to be used while either attached to a tripod, or for mobile use while installed or mounted on a vehicle via a swivel mount apparatus.
Current mounting devices do not allow antennas to be easily installed on, or removed from a vehicle, while permitting operators to efficiently and conveniently manipulate the antenna in order to communicate with satellites while installed on the vehicle. Moreover, existing mounting devices typically require that the entire vehicle be physically moved (e.g., rotated) to enable line of sight communication between the antenna and an orbiting satellite. Accordingly, a need exists for an adjustable SATCOM antenna mounted on a mobile equipment item (such as a CMV or GMV) that can be rotated manually to acquire satellite reception without having to move the entire vehicle.
In an illustrative embodiment of the present disclosure, a swivel mount apparatus for coupling an antenna to a vehicle includes a first member configured to couple to a mounting interface on a vehicle, a second member rotatably coupled to the first member, and a mounting post affixed to the first member and extending upwardly relative to the first member.

The fasteners 32 may be conventional bolts which form part of the original vehicle 20. In other words, fasteners 32, illustratively comprise pre-existing bolts adapted to couple together at least two parts of the vehicle 20. In certain illustrative embodiments, the fasteners 32 are conventional bolts configured to secure a screen or grille 33 to the hood 24.
As detailed above in connection with FIG. 1, antenna system 16 generally includes antenna post 12 mechanically coupled to antenna 10. In the disclosed embodiment of FIG. 3, antenna system 16 is mechanically coupled to swivel mount 30 via antenna post 12 and by one or more fasteners which are described in further detail in the disclosed embodiment of FIG. 6. Additionally, as indicated above in the description of FIG. 2, vehicle 20 includes a passenger compartment 25 which extends between a driver side 26a and a passenger side 26b, and hood 24 includes a plurality of mounting locations 22a, 22b, 22c. Apertures, illustratively entry/egress openings such as doors or windows 27a and 27b, are formed within the driver side 26a and the passenger side 26b of the passenger compartment 25. In the disclosed embodiment of FIG. 3, antenna system 16 is illustratively installed via mounting location 22a located in front of the passenger side 26b of vehicle 20. Stated another way, in the disclosed embodiment of FIG. 3, when seated facing the forward direction in the passenger compartment of vehicle 20, antenna system 16 is mounted via mounting location 22a that is farthest to the right. The forward direction is determined relative to the orientation of vehicle 20.
FIGS. 4A and 4B are detailed perspective views of an exemplary embodiment of the present disclosure wherein antenna system 16 is mounted on top of hood 24 of vehicle 20 at an upper interface surface 34. As indicated above in the description of FIG. 3, swivel mount 30 enables the installation and lower mounting of antenna system 16. Swivel mount 30 further includes a first member or base 40 and a second member or upper support 42. As shown in the illustrative embodiment of FIG. 5, first member 40 comprises a plate 44 having a length of 33⁄4 inches and a width of 2 inches. Illustratively, second member 42 includes an angle member 46 having a length of 3 inches, a width of 1 inch, and a height of 1 inch.
First member 40 is configured to receive fastener 32 which mechanically couples first member 40 to hood 24 via fastener 32 being in threaded connection with coupling point 28. Second member 42 is rotatably coupled to first member 40 and is retained in place via one or more retaining members 52, which are described in further detail in the illustrative embodiment of FIGS. 6 and 7. Second member 42 includes a first angle member 54 and a second angle member 56 coupled to angle member 46, illustratively through welds 55. A receiving space 57 is defined between a first receiving wall 54a of the first angle member 54 and a second receiving wall 56a of the second angle member 56. Illustratively, receiving space 57 receives antenna post 12 of antenna system 16, and antenna post 12 is mechanically coupled to second member 42 via one or more fasteners 58. As indicated above, second member 42 is rotatably coupled to first member 40 thereby defining an azimuth pivot axis 59 that extends in a vertical direction perpendicular to first member 40. First member and second member may be manufactured from a variety of different materials such as aluminum, cast iron or steel.
When antenna system 16 is mounted on top of hood 24, second member 42 causes antenna system 16 to be manually rotatable about azimuth pivot axis 59, wherein the degree of rotation is between 0 degrees and 360 degrees. Swivel mount 30, and in particular second member 42, further enables antenna system 16 to be manually rotatable by an operator or occupant residing inside the passenger compartment 25 of vehicle 20. Because antenna system 16 is manually rotatable, the driver of vehicle 20 is not required to rotate or maneuver vehicle 20 in order to orient or direct antenna system 16 to a particular desired location. For example, in one illustrative embodiment of the present disclosure, antenna system 16 may be manually rotated, via second member 42, and directed to a certain area of the sky in order to acquire a communications link with a particular orbiting satellite. In another illustrative embodiment, antenna system 16 may be manually rotated, via second member 42, and oriented in a particular direction to establish a communications link with various ground based telecommunications facilities including radio stations, news stations or any other facility transmitting or receiving information via electro-magnetic signals. In yet another illustrative embodiment, antenna system 16 may be manually rotated, via second member 42, and oriented in a particular direction to establish a communications link with various commercial, private, or military aircraft.
According to this exemplary embodiment, in addition to being rotated about azimuth pivot axis 59, antenna 10 may also be rotated about elevational pivot axis 17 to achieve a desired elevation or altitude relative to hood 24 or another location of vehicle 20. The rotational and altitudinal adjustment assists antenna 10 acquire a reciprocal SATCOM link via line of sight communication with a particular orbiting satellite. In one aspect of this embodiment, the altitude or elevation of antenna 10 relative to vehicle 20 is adjusted via a pivot pin 13 defining the elevational pivot axis 17. As detailed above, the altitude is adjusted about pivot pin 13, which may further include a conventional friction lock.
With reference to FIG. 5, the target mounting location 22a and associated coupling point 28 is illustratively within a first distance (D1) from the passenger side window 27b. The distance D1 is configured to enable an occupant (or a robotic armature) disposed within the passenger compartment 25, illustratively seated, to access the mounting fastener 32 at mounting location 22a from the passenger side window 27b. The target mounting location 22a includes existing coupling point 28 and cooperating coupling member 32 that is accessible from outside the vehicle 20 without disassembly of the antenna 10. The target mounting location 22a includes a structure adapted to couple at least two parts of the vehicle together. Illustratively, the at least two parts includes grille 33 and hood 24 coupled together with fastener 32.
With further reference to FIG. 5, the retaining member 52 is illustratively within a second distance (D2) from the passenger side window 27b for other entry/egress openings, such as an open door). In one illustrative embodiment, the distance D2 is configured to enable an occupant (or a robotic armature) disposed within the passenger compartment 25, illustratively seated, to reposition the antenna 10 from the passenger side window 27b. More particularly, from the passenger side window 27b the occupant can reach the retaining member 52 to tighten and/or loosen the wing nut 72 to rotationally reposition the antenna about the azimuth pivot axis 59. Illustratively, distance D2 is less than distance D1, wherein both distances D1 and D2 are less than the arm length of an average adult (e.g., about 25 inches).
FIG. 6 is an exploded perspective view of an exemplary swivel mount 30, including threaded coupling point 28, one or more fasteners 32, and antenna post 12. In the illustrative embodiment of FIG. 6, first member 40 is further defined as including an opening, such as thru-hole 50 which receives fastener 32. Fastener 32 enables first member 40 to be affixed and mechanically coupled to hood 24. As indicated above in the description of FIG. 2, threaded coupling point 28 may be a machined or drilled hole of a predetermined depth sufficient to receive the threads of fastener 32 such that first member 40 may be affixed to hood 24 via fastener 32 being in threaded connection with coupling point 28. Moreover, as indicated above, second member 42 is rotatably coupled to first member 40 and is retained in place via one or more retaining members 52. The retaining member 52 provides quick connect and disconnect functionality with regard to assembly of swivel mount 30.
With further reference to FIG. 6, second member 42 further illustratively includes first angle member 54 and second angle member 56 wherein a receiving space 57 is defined between first receiving wall 54a of first angle member 54 and second receiving wall 56a of second angle member 56.

Antenna post 12 may include one or more holes 61 which may be drilled or machined such that the holes 61 create openings through antenna post 12. As may be appreciated, the angle members 54 and 56 assist in securing the antenna post 12 against forces in multiple axes. For example, the receiving walls 54a and 56a help prevent rotation of the antenna post 12 about an axis extending parallel to fasteners 58 (i.e. perpendicular to the longitudinal axis of the antenna post 12 and parallel to the receiving walls 54a and 56a). The receiving walls 54a and 56a also help prevent translational movement of the antenna post 12 in a direction perpendicular to the walls 54a and 56a. 
In the illustrative embodiment of FIG. 6, antenna post 12 includes a cylindrical wall having a pair of holes 61 receiving fasteners 58. Second member 42 may be further described as a third angle member 46 including a horizontal section 60 and a vertical section 62, wherein first angle member 54 is in welded connection with a first portion of vertical section 62 and second angle member 56 is in welded connection with a second portion of vertical section 62. Second member 42 further includes one or more threaded holes 51 wherein each threaded hole receives a single fastener 58. The depth of threaded hole 51 is equal to the thickness of vertical section 62. To affix antenna post 12 to second member 42 a single fastener 58 is inserted through each of the two holes 61 of antenna post 12. The fastener 58 is then screwed into threaded hole 51 of second member 42 so that the threads of fastener 58 fully engage the threads of threaded hole 51, thereby mechanically coupling antenna post 12 to second member 42 via at least one fastener 58 being in threaded connection with at least one threaded hole 51.

As indicated above in the description of FIGS. 4A and 4B, second member 42 is rotatably coupled to first member 40 and is retained in place via at least one retaining member 52. Second member 42 further includes hole 50 which receives mounting post 68. With regard to first member 40, in one illustrative embodiment of the present disclosure, the distance from the center of mounting post 68 and the center of hole 50 is at least 31⁄4 inch.
In the illustrative embodiment of FIG. 6, retaining member 52 includes a lock washer 70, and a wing nut 72 including tabs 74 to facilitate rotation by a user. Retaining member 52 ensures that second member 42 remains in rotatable connection with first member 40 via mounting post 68. Additionally, wing nut 72 is configured to be in threaded connection with mounting post 68. Wing nut 72 may be rotated clockwise to lock second member 42 into a desired position to produce a force sufficient for precluding rotation of second member 42 relative to first member 40. When wing nut 72 is fully tightened such that second member 42 is locked into a desired position, lock washer 70, positioned under wing nut 72, helps to ensure wing nut 72 does not loosen from vibrations caused by vehicle 20. Once tightened, wing nut 72 may also be rotated counterclockwise to loosen and enable rotation of second member 42 relative to first member 40.
Swivel mount 30 may further include one or more washers 75, wherein one washer 75a receives mounting post 68 and is positioned between first member 40 and second member 42, and another washer 75b also receives mounting post 68 and is positioned between second member 42 and lock washer 70. As indicated above in the description of FIG. 5, second member 42 includes a first angle member 54 and a second angle member 56 wherein a receiving space 57 is defined between first angle member 54 and second angle member 56. Receiving space 57 receives antenna post 12 (FIG. 6) and antenna post 12 is mechanically coupled to second member 42 via one or more fasteners 58. In one illustrative embodiment of the present disclosure, receiving space 57 has a width of 1 inch and a depth of 1 inch. Second member 42 further includes one or more threaded holes 51 wherein each threaded hole receives a single fastener 58. To assemble swivel mount 30, mounting post 68 receives a first washer 75a, then second member 42 is received by mounting post 68 via hole 50 so that second member 42 is positioned atop first member 40. Mounting post 68 then receives a second washer 75b as well as lock washer 70 and wing nut 72. Each threaded hole 51 receives a single fastener 58.
In alternate illustrative embodiments of the swivel mount 30, retaining member 52 may include a variety of retaining devices other than lock washer 70 and wing nut 72. FIG. 8 is an illustration of another illustrative embodiment of a swivel mount 80 according to the present disclosure. For example, in swivel mount 80, the retaining device is detent pin 81 which also enables second member 42 to be rotatably coupled to mounting post 68. Detent pin 81 includes ring 82, ball lock 84 and pin 86. Swivel mount 80 includes substantially the same components as swivel mount 30 except that in the disclosed embodiment of FIG. 8, lock washer 70 and wing nut 72 are replaced by detent pin 81. Additionally, mounting post 68 includes a hole 50 for receiving pin 86 of detent pin 81. Detent pin 81 may be grasped by ring 82 and quickly inserted into hole 50 of mounting post 68. Ball lock 84 helps to lock pin 86 in hole 50 and retain second member 42 in a desired orientation relative to first member 40.

An illustrative method of manufacturing, installing and/or coupling antenna 10 to a vehicle 20 includes the steps of identifying and analyzing candidate mounting support surfaces on vehicle 20 to determine a target mounting location 22a. Next, the installer identifies the form, fit and function of the antenna 10 relative to the target mounting location 22a. As further detailed herein, the target mounting location 22a is within a first distance (D1) from the passenger side window 27b. The fastener 32 is inserted through the thru-hole 50 in the first member 40 and threaded into the opening 28.
First washer 75a is received over the mounting post 68, and an opening 69 in the second member 42 receives the mounting post 68. The second washer 75b is received over the mounting post 68 above the second member 42. The lock washer 70 is received over the mounting post 68, and the wing nut 72 threadably coupled to the mounting post 68. The retaining member 52 provides a quick connect and disconnect structure that provides a first force as applied by the user to prevent decoupling of the second member 42 (and antenna 10) from the first member 40. The retaining member 52 rotationally secures the antenna 10 for 360 degree rotation about azimuth pivot axis 59. The wing nut 72 is positioned within a second distance (D2) from the passenger side window 27b defined such that an occupant and a robotic armature disposed within the passenger compartment 25 may engage and reposition the antenna 10.
Illustratively, the first member 40 is adapted to releasably couple with the retaining member 52 and the existing fastener 32 so as to avoid interference between the mount 30 and sections of the vehicle 20 (i.e., the hood 24 and the passenger compartment 25). In operation, an occupant supported within the passenger compartment 25 can reach, from the passenger side window 27b, the wing nut 72 to unlock the second member 42 for rotation about the azimuth pivot axis 59 within a range of 360 degrees. Similarly, the occupant supported within the passenger compartment 25, from the passenger side window 27b, can reach the pivot pin 13 to unlock the antenna 10 for rotation about the elevational pivot axis 17. The method further includes providing for a dual use nature of the antenna 10, wherein the antenna 10 may be mounted on the tripod 14 separate from the vehicle 20 and also supported by swivel mount 30 on the vehicle 20, both as part of communications with a satellite.
