Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to portable antenna systems and, more particularly, the invention relates to a portable satellite antenna system for semi-permanent use at a variety of rugged and remote locations.

2. Discussion of the Background

Customers, especially business customers, continually require a lower cost portable automatic satellite acquisition antenna system especially for two-way internet applications at remote locations.

In the past a number of portable collapsible satellite antenna systems have been patented. For example, U.S. Pat. Nos. 7,369,097 and 5,660,366 teach portable dish antennas supported by collapsible tripods. U.S. Publication No. 2007/0279308 discloses the use of suction cups to remove a satellite antenna from one surface to another. U.S. Pat. No. 5,646,638 provides a portable collapsible satellite dish antenna system for hand carrying from one location to another. And, U.S. Pat. No. 6,734,830 shows a portable adjustable stand for a satellite dish antenna using a stand having a pair of parallel spaced, laterally adjustable longitudinal brackets. Satellite antenna systems can be disassembled and/or folded for transportation in cases. U.S. Pat. No. 7,397,435 shows a quick release stowage system for transporting a mobile satellite antenna. U.S. Pat. No. 7,218,289 also shows a portable microwave reflector antenna that can be stowed in two hard shell airline cases.

Some prior approaches use ballast to stabilize the deployed portable collapsible satellite antenna system especially when the deployed system is used for a period of time. U.S. Pat. Nos. 6,682,029 and 5,760,751 shows a collapsible satellite dish antenna mount having a hollow base container for holding ballast. U.S. Pat. No. 6,798,387 sets forth a non-penetrating roof mount for a transportable satellite antenna using ballast such as cement blocks.

A need further exists for an easily disassembled satellite antenna that is compactly transported, but easily assembled for use not only on a portable mount such as collapsible non-penetrating mount, but also mounted on a lightweight portable tripod or even mounted on a pole. The satellite antenna system has a further need to have automatic azimuth, automatic elevation and automatic skew mechanisms.

A final need exists for such a semi-permanent satellite system that will be available with cases to transport the system such as military style plastic, panel type fabricated cases or even wooden crates.

SUMMARY OF THE INVENTION

A semi-permanent portable satellite antenna system having a portable satellite antenna and a portable mount such as a non-penetrating mount, a tripod, or a pole for holding the portable satellite antenna on a surface when the semi-permanent portable satellite antenna system is deployed. The portable satellite antenna assembles for deployment on the portable mount and disassembles for portability. The non-penetrating mount also collapses for portability.

The portable satellite antenna has an antenna mount with a reflector plate and a mount cap. The mount cap releasably connects to the portable mount when the semi-permanent portable satellite antenna system is deployed on the surface. The portable satellite antenna also has a reflector releasably connected to a reflector plate on the antenna mount. The reflector has a rear surface and an outer rim. A number of threaded knobs releasably connect the rear of the reflector to the reflector plate on the antenna mount. The antenna mount controls azimuth and elevation of said reflector. The portable satellite antenna also has three feed arms. A knob retained on each end of the feed arms releasably connects to the outer rim of the reflector. A feed having a skew mechanism releasably connects to the other ends of the three feed arms. When the portable satellite antenna is assembled for deployment on the surface, the antenna mount is first mounted to the portable mount. Then, knobs are used to assemble the reflector to the reflector plate in the antenna mount. The three feeds arms arm are then mounted to the rim of the reflector with the retained knobs. The feed is finally assembled to the remaining ends of the three feed arms. The process is reversed to disassemble the portable satellite antenna for transportation.

The portable satellite antenna can be mounted to a pole, a tripod, or to a portable collapsible non-penetrating mount. The portable collapsible non-penetrating mount has an elongated channel with a post having one end of the post attached perpendicularly at the center of the channel with the other end holding the deployed portable satellite antenna. A pair of angled support braces has one end attached to the post and the other end attached to the channel to rigidly support the post with respect to the channel. A pair of folding support wings is pivotally connected on either side of the elongated channel. The pair of support wings pivots upwardly towards the post for transportation and pivots down to the surface when deployed. A pair of angled locking arms having one end releasably connected to the post and the other end releasably connected to a support wing to rigidly support the post with respect to the support wings and to orient the support wings to lay flat on the surface. The pair of locking arms easily release from the post and the support wings for portability. When deployed, ballast such as cement blocks are placed in the support wings to stabilize the satellite antenna mount to the surface.

The summary set forth above does not limit the teachings of the invention especially as to variations and other embodiments of the invention as more fully set out in the following description taken in connection with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

In FIG. 1, the assembled portable satellite antenna 10 of the invention is shown held by the portable collapsible non-penetrating mount 20 of the invention on a surface 30 such as ground. This shows the semi-permanent portable satellite antenna system of the invention deployed for semi-permanent use on a surface. Any surface 30 could be used such as a platform, concrete pad, roof, wood decking, etc. The portable satellite antenna 10 of the invention has an antenna mount 40 and a reflector 50 having feed arms 60a, 60b, and 60c (generally referred to as feed arms 60) and a feed 70. The feed 70 preferably also has a mechanism for skew adjustment. Also shown are the electronics control box 80, the elevation actuator 90, and the azimuth motor 95. The reflector 50, depending on the application, may be a 1.2 or 0.96 meter dish, but any sized reflector 50 can be used. The antenna mount 40 can also be held by a post into the surface such as a ground surface 30, held by a tripod on the surface 30, etc. For purposes of this invention, the term “portable mount” is defined to be a post, a tripod, or a non-penetrating mount such as the non-penetration mount of the invention disclosed herein.

Details of the collapsible non-penetrating mount 20 of the invention are shown in FIGS. 1 and 2 to include a pair of opposing support wings 100a and 100b, a pair of releasable locking arms 110a and 110b, an elongated channel 120 to which is attached a post 130 at one end 132. The post 130 in one embodiment is integrally attached by welding the end 132 to the bottom of the channel 120 and the post 130 is oriented perpendicular to and in the center the channel 120. The post 130 can be a metal pipe having any suitable diameter such as 3 inches or any suitable shape such as square or rectangular rather than circular.

Support braces 140a and 140b provide rigid support to the post 130 from opposing sides 122a and 122b of the channel 120. Support braces 140a and 140b are attached to the elongated channel 120 and to opposing sides of the support post 130 such as by welding, bolts or by any other suitable attachment.

The portable satellite antenna 10 has a cylindrical mount cap 98 which goes over the post 130 and is connected with bolts 99 such as ⅜ inch bolts. In the event, the post 130 is not circular; the cap 98 will have a configuration that matches the post. The mount cap 98 mounts to any suitable portable mount.

The angled locking arms 110a, 110b and the angled support braces 140a, 140b form a substantially pyramidal rigid support structure for post 130 which firmly holds the assembled portable satellite antenna 10 in the deployed position as shown. Each support brace 140a and 140b has one end is attached to the side of the channel 120 a first set distance from the post 130 as shown by arrow 280 and the other end attached to the post 130 a second set distance from the bottom of the channel 120 as shown by arrow 282. Each releasable locking arm 110a (and 110b) has one end 114a (and 114b) attached to the support wing 100a (and 100b) a first distance from the post 130 as shown by arrow 284 and the other end 112a (and 112b) attached to the post 130 a second distance from the bottom of the channel 120 as shown by arrow 286.

As shown in FIG. 1, one end 112a, 112b of the locking arms 110a, 110b is connected with a bolt 150 having a knob 152 to the post 130 so as to be releasable. The opposing ends 114a, 114b of the locking arms 110a and 110b are connected to pivots 160a and 160b on center brackets 170a and 170b of support wings 100a and 100b so as to be releasable. The center brackets 170a and 170b are welded to the outer rectangular frame 180a and 180b of the support wings 100a and 100b. Releasable hinge pins 190a and 190b are used to connect the locking arms 110a and 110b to the center brackets 160a and 160b.

The portable non-penetrating mount 20 shown deployed in FIGS. 1 and 2 on surface 30. The non-penetrating mount 20 is shown folded (collapsed) in the directions 200a and 200b of FIGS. 2 and 3 for portability and for easy transport. The portability configuration shown is achieved by removing hinge pins 190a and 190b (shown in FIG. 2). In addition, the threaded knob 152 is removed from the bolt 150 to fully release the locking arms 110a and 110b from opposing sides of the post 130. The support wings 100a and 100b are then moved in directions of 200a and 200b upwardly to assume the folded orientation shown in FIG. 3. Each support wing 100a and 100b is connected at pivot points 210 to the channel 120. The locking arms 110a and 110b have been fully released and removed from the portable non-penetrating mount 20 and are put inside of the post 130 for stowing along with the hinge pins 190a and 190b. The knob 152 and bolt 150 are then used to pass through formed holes 172 of the support brackets 170a and 170b through a corresponding formed hole 134 in the post 130 and above the locking arms 110a and 110b stored within the post 130. The bolt 150 and the knob 152 firmly hold the two opposing support wings 100a and 100b firmly against opposing sides of the post 130 for portable transport as shown in FIG. 3a. The bolt 150 passing through the center of the post 130 holds the two locking arms in the post 130 for stowing.

FIGS. 1 and 4 show ballast 400 comprised, for example, of twelve cement cinder blocks placed in the support wings 100a and 100b to provide sufficient weight to firmly hold the portable non-penetrating mount 20 to the ground 30. The blocks 400 rest on edges 102 of support wings 100a and 100b, edges 122a, 122b of channel 120 and edges 174 of center brackets 170 as best shown in FIG. 2. The weight of the twelve cinder blocks is approximately 500-600 pounds. Any suitable ballast 400 can be provided such as sand bags, logs, or even large rocks. In other embodiments, the bottoms of the opposing support wings 100a and 100b are solid such as a plate of metal and sand or dirt can be placed on the plates as ballast 400.

The portable collapsible non-permanent mount 20 of the invention shown in FIGS. 1-4 has a folded state (FIG. 3) for easy transport and a deployed state (FIG. 2) for use in holding the satellite antenna 20. During transport the locking arms 110 and hinge pins 190 are stowed inside the post 130 so that all components are transported together.

In summary, the semi-permanent collapsible portable mount 20 of the invention uses an elongated channel 120 to support a perpendicular post 130 for holding the portable satellite antenna 10. A pair of support braces 140 have one end attached a first set distance above the elongated channel 120 to the post 130 and the other end attached a second set distance from the post on the elongated channel 120. The pair of support braces 140 opposes each other on the elongated channel 120. A pair of support wings 100 is pivotally connected to the elongated channel 120. The support wings 100 pivot to the post 130 when stowed for portable movement and pivot to onto a surface 30 when deployed. A pair of locking arms 110 have one end releasably connected a first distance above the elongated channel 120 to the post 130 and a second end releasably connected a second distance from the post 130 on one of the pair of support wings 100. The pair of locking arms 110 opposes each other on the pair of support wings 100 when deployed, but the arms 110 release for portability.

In FIG. 5, the details and the assembly steps for the portable satellite antenna 10 of the invention are set forth. The portable satellite antenna 10 of the invention is shown disassembled and separate from the deployed portable non-penetrating mount 20 on surface 30. The portable satellite antenna 10 can be used on any portable mount.

In the first step, the semi-portable mount 40 having the mount cap 98, the elevation actuator 90, the outdoor electronics box 80, and the azimuth motor 95 is moved as a unit in the direction of arrow 510 so that the mount cap 98 fits over and rests on the upper end 136 of post 130. At this step, the six bolts 99 are tightened with a wrench to retain the cap 98 against the end 136. Any suitable number of bolts can be used. The mount cap 98 can also mount to a post in the ground or onto a tripod on the ground.

In the second step, the reflector 50 is moved as a unit in the direction of dotted lines 520 toward the dish plate 530 in the antenna mount 40 as shown in FIG. 11. The rear 52 of the reflector 50 has four posts 54 with threaded studs 55. The threaded studs 55 pass through the formed holes 532 in the dish plate 530. Knobs 534 are then used to quickly thread onto the studs 55 to firmly hold the reflector 50 to the dish plate 530 as shown in FIG. 1. Each knob 534 has a formed threaded hole 536 in a collar portion 538. Any suitable number of threaded posts 54 can be used. No tools are required to attach the reflector 50 to plate 530.

In the third step, the three feed arms 60 (60a, 60b, and 60c) are attached as shown in FIG. 5 to the rim of the reflector 50 using three stainless steel knobs 62a, 62b, and 62c by moving the arms 60 in the direction of arrows 540 to affixation holes 704. In FIG. 6 feed arm 60c is shown with angled ends 610 and 620 with a body 630 therebetween. At each end 610, 620 is a knob 62c. Each knob 62c has a cylindrical standoff portion 640 and a threaded stud portion 650. A retainer clip 660 is used to hold the knob 62c to one of the ends 610, 620. As shown in FIG. 7, the reflector 50 has an outer rim 700 that has formed holes 704 (three, one for each feed arm 60a, 60b, and 60c). Behind the rim 700 is a plate 720 that is held by two bolts 730 which engage threaded holes 740 in plate 720. The threaded stud portion 650 of knob 62c engages a threaded hole 750 in the plate 720. The structure of FIG. 7 is the same for the engagement of all three knobs 60a, 60b and 60c to the rim 700 of the reflector. The other end 620 of feed arm 60c uses knob 62c in a similar fashion to engage a threaded hole 800 in the block 810 of the feed horn/skew mechanism 70. Feed arm 60c connects in the same structural manner. The end 900 of feed arm 60a does not have a knob, but the end 900 slides into a formed slot 910 in the block 810 as shown in FIG. 9. The three ends 740a, 740b, and 740c of arms 60a, 60b, and 60c are easily attached to the rim 710 of the reflector 50 with knobs 62a, 62b, and 62c respectively. The number of feed arms is a matter of design choice. No tools are required to attach the feed arms 60 to the reflector 50.

In the fourth step, the feed 70 is moved in the direction of arrow 550 and attaches to the feed arms 60. In FIG. 5, the feed 70 is attached to the three feed arms 60 with two knobs 62b and 62c and with end 900 sliding into slot 910. No tools are required. As shown in FIG. 1, the weight of feed 70 causes the feed 70 to firmly connect to end 900.

It is to be understood that a number of different mechanical designs can be utilized to quickly connect to and release from the feed arms 60a, 60b, and 60c to the reflector 50 and to the feed 70.

In FIG. 10, the rear reflector 50 is shown with the three knobs 62a, 62b, and 62c connecting the three feed arms 60a, 60b and 60c. In the center of the reflector are four threaded posts 54 and four standoff posts 56. As shown in FIG. 1, the four standoff posts 56 abut the dish plate 530.

The portable satellite antenna 10 of the invention shown in FIGS. 1 and 5-11 has a disassembled state (FIG. 5) for easy transport and a deployed state (FIG. 1) mounted on a portable mount.

In summary, the portable satellite antenna 10 has an antenna mount 40 with a dish plate 530 and a mount cap 98. The mount cap 98 releasably connects to the portable mount 20 such as the semi-permanent portable satellite antenna system. The rear of the reflector 50 releasably connects to the reflector plate 530 in the antenna mount 40 by using a number of threaded knobs 534. The antenna mount 40 controls azimuth and elevation of the reflector 50 when connected to the reflector plate 530. The portable satellite antenna 10 has three feed arms 60. A knob 62 is retained on each end of the feed arms 60 for releasably connecting to the outer rim of the reflector 50. A feed 70 having a skew mechanism releasably connects to the three feed arms 60.
