BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to the field of satellite dish antennas and more particularly to ones that are compact and portable.
2. Discussion of the Background
Satellite dish antenna systems that are compact and portable are very popular and enable the operators to manually carry and set up their systems virtually anywhere. Most such systems have foldable components that can be extended in use and retracted for carrying and storage. However, such current designs tend to be fairly elaborate with multiple moving parts that are both complicated to manufacture and use.
With this and other problems in mind, the present invention was developed. In it, the components of the system were specifically designed to perform multiple functions relating to both the operation and portability of the antenna system thereby reducing the number and complexity of the various parts and reducing the overall weight and size of the portable system.
SUMMARY OF THE INVENTION
This invention involves a lightweight, portable satellite dish antenna system. The system has base and lid portions which can be configured relative to each other in carrying and deployed positions. The base and lid portions are substantially the same size and shape and have respective interior and exterior sides. The satellite dish antenna of the system is pivotally mounted to the interior side of the lid portion.
In the carrying position, the satellite dish antenna is retracted to align with the interior side of the lid portion and the lid and base portions are secured together with the interior sides thereof facing and abutting each other. In the deployed or operating position, the lid portion is inverted and placed atop the base portion with the exterior side of the lid portion and the interior side of the base portion facing and abutting one another. The exterior side of the lid portion and the interior side of the base portion have mating bearing surfaces extending about a central, vertical axis. In use, the satellite dish antenna can be elevated as desired with the lid portion inverted atop the base portion. The lid portion can subsequently be rotated relative to the base portion to the desired azimuth position about the vertical axis with the mating bearing surfaces in contact with each other. The lid and base portions can thereafter be drawn tightly together by a central, threaded locking bolt to fix the lid portion in the operating position on the base portion.

DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1-10 sequentially show how the various components of the portable satellite dish antenna system 1 of the present invention can be manipulated to convert the system 1 from its compact, carrying configuration of FIG. 1 to a fully deployed configuration supported either on a flat surface 2 (FIG. 7) or on a tripod arrangement such as 4 (FIGS. 8-10). The system 1 in this regard has a base portion 3 (see FIG. 11) and a lid portion 5. In the carrying configuration of FIGS. 1 and 12, the base and lid portions 3,5 are securely latched together by the latching mechanisms 7 (FIGS. 11-12) wherein the system 1 can be manually carried by the handle 9 (FIG. 12). Flat sections 11,11′ are provided on the peripheral surfaces 13,13′ of the base and lid portions 3,5 (FIGS. 12-14). In this manner, the system 1 can be easily and quickly set down on any level surface such as 2 when not in use. The flat sections 11,11′ as shown are aligned adjacent one another substantially in a common plane when the base and lid portions 3,5 are secured to each other. Additionally, the handle 9 as illustrated in FIGS. 12 and 14 is positioned on at least one of the peripheral surfaces (e.g., 13′) substantially opposite the flat sections 11,11′.
To deploy the portable satellite antenna system 1, the substantially hollow lid portion 5 is preferably first filled with a flowable ballast material (e.g., a gallon of water or sand) to add weight (e.g., 8 pounds) to it. This can be easily and conveniently done by removing the fill cap 15 (FIG. 12) with the secured system 1 in the upright position of FIG. 12. With the fill cap 15 back in place, the system 1 can be placed flat on its base portion 3 as in FIGS. 3 and 11 and the latch mechanisms 7 released. With the latch mechanisms 7 released, the lid portion 5 can be removed from the base portion 3 and inverted (FIG. 4) and then placed atop the base portion 3 (FIG. 5). In the position of FIG. 5 with the base portion 3 on a relatively flat surface 2, the base and lid portions 3,5 can be further leveled if desired. This can be done for example by using the bubble level 17 (see FIG. 10) and screwing the feet 19 (FIG. 5) in and out or by adjusting the tripod legs 21 in the arrangement of FIGS. 8-10. The base portion 3 could also be removably secured as for example by the fixed, rubber feet 19′ of FIGS. 10-11 to a separate tripod arrangement having its own central platform and leveling aids if desired.
In any event and once the desired leveling is accomplished (e.g., on the surface 2 of FIG. 5), the dish antenna 25 can be elevated by loosening the thumb screws 27 on both sides of the lid portion 5 and pivoting the dish antenna 25 (FIGS. 6 and 15) about the substantially horizontal axis H to the desired elevation. The axis H in this regard is preferably spaced from the axis V and substantially perpendicular thereto. In the desired elevation, the dish antenna 25 extends substantially in a plane P (FIG. 15) at angle substantially between zero and 90 degrees to a horizontal plane containing the axis H. With the thumb screws 27 of FIGS. 6 and 15 re-tightened, the lid portion 5 can be rotated (FIGS. 7 and 16) relative to the base portion 3 about the vertical axis V to the desired azimuth position. Once in the desired azimuth position of FIG. 16 and as explained in more detail below, the lid portion 5 can be locked in place by tightening the central locking bolt 33 of FIGS. 17-18. In doing so, the lid portion 5 and base portion 3 are firmly drawn together into a fixed position relative to each other (FIG. 19).
More specifically and as best seen in FIG. 20, the base and lid portions 3,5 have respective interior and exterior sides 35,37 and 35′,37′. In the carrying position of FIG. 20, the interior sides 35,35′ are facing and abutting one another (see also FIG. 21) and are securely held in place by the latching mechanisms 7. The latching mechanisms 7 as shown in FIGS. 20 and 21 have segments 7′,7″ on the respective peripheral surfaces 13,13′ of the base and lid portions 3,5. The base and lid portions 3,5 are then secured by the latching mechanisms 7 in a predetermined, fixed position relative to each other about the vertical axis V with the interior sides 35,35′ facing and abutting one another. In contrast and in the deployed or operating position with the lid portion 5 inverted and placed on the base portion 3 as in FIG. 15, the exterior side 37′ of the lid portion 5 is facing and abutting the interior side 35 of the base portion 3.
The exterior side 37′ of the lid portion 5 in this regard has a bearing surface 39′ spaced from and extending substantially about the vertical axis V as perhaps best seen in FIG. 3. Similarly, the interior side 37 of the base portion 3 has a mating bearing surface 39 (FIG. 4). In the position of FIG. 18 with the lid portion 5 inverted atop the base portion 5, the respective concave and convex bearing surfaces 39,39′ then abut and mate with one another (see also the enlarged view of FIG. 18a). In this manner, the lid portion 5 can thus be manually and slidably moved or rotated about the vertical axis V relative to the base portion 3 (e.g., from the position of FIG. 15 to that of FIG. 16). Once in the desired rotational or azimuth position (e.g., FIG. 16) and as discussed above, the threaded locking bolt 33 can be tightened (FIGS. 18-19) to draw the base and lid portions 3,5 firmly together into a fixed position relative to each other. The slots 41,41′ in this regard receive the threaded shaft 33′ of the bolt member 33 with the lower slot 41 preferably provided with a threaded insert 43 as shown in FIGS. 18 and 19. The shaft 33′ is preferably centered as also shown in FIGS. 18-19 to extend along an axis substantially collinear with the vertical axis V.
The base and lid portions 3,5 are preferably substantially the same size and shape (e.g., cylindrical with each about 15 inches across and 4.5 inches deep). The base and lid portions are also preferably molded of lightweight plastic (see FIG. 22) to save weight and give the system 1 a clean and attractive look. Combined together, the plastic base and lid portions 3,5 weigh only about ten pounds with the hollow lid portion 5 empty of any ballast material. In the carrying position of FIG. 1, the compact and portable system 1 can then be easily handled and placed wherever desired. The cylindrical shapes of the base and lid portions 3,5 also make it easy and convenient to manipulate them to abut the respective ends 35, 35′, and 37′ of the cylindrical shapes in the carrying and operating positions. The system 1 as discussed above can be set on a relatively flat surface such as 2 in FIGS. 1-7 or supported on a tripod arrangement such as 4 in FIGS. 8-10 secured to the exterior side 37 of the base portion 3. A separate tripod arrangement with its own central platform could also be used with the base portion 3 removably attached thereto adjacent the exterior side 37. Additionally, the system 1 can be provided with tent stakes such as 45 in FIG. 4 that are storable in the base portion 3. In use, the stakes 45 can be hooked through loops or holes (e.g., 47 in FIG. 17) about the peripheral surface of the base portion 3 and driven into the ground if no hard surface or tripod is available.
