Retractable vehicle-mounted mobile surveillance equipment (also interchangeably referred to as “sensors”) is well-known in the art. One example of such equipment is Freedom-On-The-Move (FOTM 3.0), which is commercially available from Freedom Surveillance, LLC dba STRONGWATCH®, Scottsdale, Ariz. The surveillance equipment is mounted to a flatbed of a truck. In its retractable state, the equipment fits entirely within the flatbed so that it can be completely hidden and protected from the elements using a conventional flatbed covering.
However, it is desirable to include additional surveillance equipment on the vehicle that is fully retractable into the interior space of the vehicle when not in use, and which can be retracted out of the vehicle during use. It is further desirable for the additional surveillance equipment to be hidden from view and protected from the elements when it is fully retractable into the interior space of the vehicle. The present invention fulfills such a need.
A vehicle is provided having an interior cabin and a roof at the top of the interior cabin. The vehicle includes a flatbed, an opening in the roof of the interior cabin, a first retractable telescoping structure having a first set of surveillance equipment mounted to the flatbed, and a second retractable telescoping structure having a second set of surveillance equipment mounted so as to extend through the opening of the roof, and to fully retract into the interior cabin. A sealing device mounts to the second retractable telescoping structure below the second set of surveillance equipment and oriented parallel to the roof of the interior cabin. The sealing device includes an elastically deformable gasket that elastically deforms during travel of the sealing device through the roof of the interior cabin when the second set of surveillance equipment extends through the opening in the roof during extension of the second retractable telescoping structure, and when the second set of surveillance equipment retracts into the interior cabin during retraction of the second retractable telescoping structure.
The foregoing summary, as well as the following detailed description of the invention, will be better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, there are shown in the drawings embodiments which are presently preferred. It should be understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown. In the drawings:
Certain terminology is used herein for convenience only and is not to be taken as a limitation on the present invention. The words “a” and “an”, as used in the claims and in the corresponding portions of the specification, mean “at least one.”
Referring to
i. A flatbed 12.
ii. A retractable sunroof/moonroof 14 (hereafter, referred to as “sunroof 14”), preferably, having a horizontally retractable mechanism. More broadly, the sunroof 14 may simply be an opening cut through the roof of the vehicle 10 to allow objects to protrude out of the interior cabin of the vehicle 10. Thus, the sunroof 14 is one embodiment of such an opening. In one preferred embodiment, the sunroof 14 is mounted in reverse and programmed so that the tilt mechanism is disabled in order to prevent dust and debris from entering the vehicle when mobile. In
iii. A first retractable telescoping structure 16 having a first set of surveillance equipment 18 mounted thereon. The first retractable telescoping structure 16 is fastened at its bottom to the floor of the flatbed 12, or to a mounting mechanism (not shown) that is fastened to the floor of the flatbed. The first retractable telescoping structure 16 retracts to a form factor that allows it, and the associated first set of surveillance equipment 18, to be completely stored in the flatbed and fully covered by flatbed cover 20, shown in its rolled up position in
iv. A second retractable telescoping structure 22 having a second set of surveillance equipment 24 mounted thereon. When fully retracted, the second retractable telescoping structure 22 and the second set of surveillance equipment 24 is completely inside of the vehicle. When the second set of surveillance equipment 24 is in use, the second retractable telescoping structure allows the second set of surveillance equipment 24 to extend through the sunroof 14 by an amount sufficient to allow the second set of surveillance equipment 24 to be fully external to the vehicle 10. In its fully extended, upright position, the second retractable telescoping structure 22 also effectively functions as a mast, and the second set of surveillance equipment 24 is preferably mounted at or near a top portion of the mast.
v. A sealing device 26 to inhibit water and/or dirt from entering the passenger compartment of the vehicle 10 through the open sunroof 14 when the second set of surveillance equipment 24 is fully external to the vehicle 10, such as when it is in use. The sealing device 26 is fixed to a platform of the second retractable telescoping structure 22 as described in more detail below, and has a form factor that slightly exceeds the length and width dimensions of the sunroof 14, so as to provide a water-tight roof cover, and so that any water and/or dirt will have a harder time penetrating into the passenger compartment of the vehicle 10 (also, referred to interchangeably as the “interior cabin” or “interior cab”). The sealing device 26 also seals the interior cabin from the external environment so that if the interior cabin is air conditioned or heated, the cold or warm air will be inhibited from escaping out through the sunroof 14. The vehicle 10 may be deployed in harsh environments, such as deserts, where extreme heat, or snow and/or ice, may be present.
i. A pedestal-type brace 36 is fastened at one end to the top surface of the scissor jack top platform 30, and is attached at the other end to the bottom surface of the rigid support plate 40 of the sealing device 26.
ii. A support stand 48 having surveillance equipment platform 50 is fastened to the top surface of the rigid support plate 40 of the sealing device 26. In one preferred embodiment, the support stand 48 has a fixed height. In another embodiment, the support stand 48 is attached to, or is integrated with, a small telescoping mast (not shown) to provide additional height for the second surveillance equipment 24 above the roof line of the vehicle 10.
iii. The surveillance equipment 24 is secured to, or mounted onto, the surveillance equipment platform 50. In one embodiment, quick connect clamp 52 is used to secure the surveillance equipment 24 to the surveillance equipment platform 50.
In one configuration, the brace 36 is formed of triangular machined bracing. The brace 36 stabilizes and supports the support stand 48 and the selected surveillance equipment that is connected on the top of the surveillance equipment platform 50 (e.g., camera, sensor, radar, drone).
The dimensions of the top platform 30 are smaller (in length and width) than the dimensions of the sunroof 14 so that the top platform 30 can extend through the sunroof 14. The overall height of the fully retracted scissor jack mechanism 28, the brace 36, the sealing device 26, the support stand 48, and the second set of surveillance equipment 24 secured to, or mounted thereon, is less than the interior height of the vehicle's interior cabin so that the second set of surveillance equipment 24 can be hidden completely inside of the vehicle's interior cabin when not in use, and when the sunroof 14 is closed, as shown in
The second retractable telescoping structure 22, here, scissor jack mechanism 28 is preferably mounted in the back seat of vehicle 10 and on the back wall of interior cabin using existing seat and seat belt mounting points so that there are no new holes or cutting that would impact the structural integrity of the vehicle 10 or impact its warranty. Alternatively, the scissor jack mechanism 28 may be fastened to a plate 32 that lays on, or is slightly elevated from, the backseat floor 34 of the vehicle 10. Alternatively, the scissor jack mechanism 28 may be bolted directly to the backseat floor 34 of the vehicle 10.
Other mechanisms that telescopically extend and retract may be used in place of the scissor jack mechanism 28 for the second retractable telescoping structure 22.
The vehicle 10 may be a conventional, commercially available pickup truck, such as a Ford® F-150®. The cab of these vehicles includes mounting points that are typically used for attaching seats, seatbelts and other typical car components, and which can be used for mounting the second retractable telescoping structure 22.
The platforms 19 and 50 of the two respective retractable telescoping structures 16 and 22 are preferable designed to allow for interchangeability of the surveillance equipment 18 and 24 mounted thereto. The surveillance equipment 18 and 24 is preferably attached to their respective platforms 19 and 50 via quick clamp structure, described in more detail below.
In one preferred embodiment, the second set of surveillance equipment 24 is a drone, and the top surface of the surveillance equipment platform 50 is a drone launching and landing platform (pad). In one alternative drone embodiment, shown in
In another alternative drone embodiment shown in
Any conventional drone and drone launching and landing platform (pad) configuration may be used for these embodiments.
In the preferred embodiment, it is desirable to use a vehicle that has a factory-installed or after-market installed sunroof, instead of cutting a custom opening into a roof of a vehicle that does not have a factory-installed or after-market installed sunroof. However, the scope of the invention does not require the use of a vehicle with a factory-installed or after-market installed sunroof. If a custom opening is cut, a leakproof cover plate may be installed over the opening when the second set of surveillance equipment 24 is not being used.

The scope of the invention is not limited to the dimensions listed above. The dimensions of the sunroof opening will determine the relative dimensions of the rigid support plate 40 and elastically deformable gasket 42.
If the elastically deformable gasket 42 shown in
The elastically deformable gasket 42 may also be formed via a mold process. In the mold process, it would not be necessary to remove the cut-out portion, since the mold process would directly form only the rectangular gasket.
The elastically deformable gasket 42 has properties of “elastic deformation,” meaning that the material always returns back to its original shape after any stress on the gasket is removed. Here, the stress occurs as the sealing device 26 is passed through the sunroof 14. Thus, the deformation is reversible. That is, no permanent deformation occurs due to stress on the gasket. In contrast to elastic deformation, plastic deformation results in a permanent altering of the original shape.
Referring again to
In one embodiment, the scissor jack mechanism 28 has a fully extended position wherein the surveillance equipment platform 50 extends through the sunroof, and an operational position wherein the surveillance equipment platform 50 is slightly above the opening of the sunroof 14. The operational position is the position when the second set of surveillance equipment 24 is performing its surveillance functions. As discussed below with respect to
In one preferred embodiment, the scissor jack mechanism 28 retracts about 3-4 inches between the positions shown in
The slight retraction that occurs to form the complete seal can either be (a) manually performed by the vehicle operator, (b) pre-programmed to account for the height of the entire assembly (stack) shown in
In one alternative embodiment, the pedestal-type brace 36 is not part of the assembly of elements associated with the second retractable telescoping structure 22 having the second set of surveillance equipment 24 mounted thereon (stack). In this alternative embodiment, the top surface of the scissor jack top platform 30 is attached directly to the bottom surface of the rigid support plate 40 of the sealing device 26. Thus, this embodiment is identical to
In yet another alternative embodiment, the sealing device 26 is formed solely of the elastically deformable gasket 42, either in a solid sheet form, or in a rectangular gasket form with a rectangular cutout center region, and is attached directly to the top surface of the scissor jack top platform 30. In this embodiment, the second set of surveillance equipment 24 may also be attached to the top surface of the scissor jack top platform 30, such as via the support stand 48. The elastically deformable gasket 42 is still positioned between the second set of surveillance equipment 24 and the top surface of the scissor jack top platform 30 so as to provide the same desired environmental sealing protection as the other embodiments.
The surveillance equipment that is mounted to each of the retractable telescoping structures includes one or more sensors. The sensors may be optical, infrared, thermal, acoustic, radar, seismic RF (to detect location and range of RF signals), or any combinations thereof, or any other known forms of surveillance sensors. One or more of the sensors may incorporate a GPS compass, inertial sensors and range-finding sensor (e.g. laser rangefinder) to determine the location of an item of interest (referred to herein as a “target”) as a set of GPS coordinates.
The sensors may communicate with each other so that they can work cooperatively. That is, each sensor can generate data that can be used to direct other sensors. For example, one sensor (e.g., radar) may detect a target and the GPS coordinates of its location, and may communicate the target location to another sensor (e.g., optical sensor). The other sensor may then use the location data of the target to either manually (if operated by a person) or automatically point the sensor at the target, such that the target is within a field of view of the optical sensor. A software system is provided to coordinate and control the operation of the platforms and the sensors mounted thereon. Sensor communication and software systems for target tracking may use systems and methods described in U.S. Pat. No. 10,267,598 (Fougnies), which is incorporated by reference herein, wherein the lead and follower scopes described in this patent are equivalent to the surveillance equipment 18 and 24 (sensors) on the respective first and second retractable telescoping structures 16 and 22.
The following are sample specifications for surveillance equipment and corresponding mounting structure, in accordance with one preferred embodiment of the present invention.
Surveillance equipment 18:
In one preferred embodiment, a leveler is provided as part of the scissor jack mechanism 28. Certain sensors, such as radar, require that the platform on which they are mounted is level with the horizon. However, depending on the terrain, the vehicle 10 may not be level. Using a leveling sensor alone or in conjunction with a gyroscope, a leveler determines the extent to which the vehicle is not level with the horizon and adjusts the sensor platform. Alternatively, the entire vehicle may be leveled using commercially available leveling systems.
In one preferred embodiment, shown in
These embodiments presume that the roof of the vehicle 10 is metallic, and that when the second set of surveillance equipment 24 is in its operational position (
The form factor and drainage properties of the sunroof 14 and outer frame of the sunroof 14 partly determines the outer dimensions of the elastically deformable gasket 42 of the sealing device 26 and how it seals against the roof of the vehicle 10. In the most protective embodiment, the outer edges of the elastically deformable gasket 42 preferably extend past the outer frame of the sunroof 14 and seat against the roof of the vehicle 10 when the second set of surveillance equipment 24 is in its operational position (
