## Background
FIELD OF TECHNOLOGY
The apparatus and method disclosed in this document pertain generally to security. More particularly, the new and useful anti-vehicle security system claimed in this document pertains to an device for restraining vehicular entry into a prohibited area. The anti-vehicle security system is particularly, but not exclusively, useful for prohibiting vehicular entry without causing either the death of vehicle occupants, or destruction of the vehicle.
BACKGROUND
An international need has arisen to block vehicular entry into prohibited areas. At least one subcategory of achieving that goal includes blocking selected vehicular entry without injury either to the occupants or to the vehicle. Vehicular restraining apparatus thus far suggested by others include complicated devices whose sophistication may render such apparatus nonfunctional precisely when needed. For example, restraining devices have been proposed that require propulsion systems for raising structural components, components that may not propel when needed. Similarly, telescoping supports and arms may not telescope when operation is desired. Other vehicle inhibitors call for frangible materials in a variety of components that must be replaced after each use, a limitation in remote areas. Accordingly, need exists in the industry for the new, useful, simple to install, and simple to operate anti-vehicle security system disclosed and claimed in this document.
SUMMARY
The anti-vehicle security system disclosed and claimed in this document includes a truss assembly formed with a plurality of monolithic stanchions. A container having a hinged door is fixed on the truss assembly. The system also includes two spaced-apart guides that extend from within the container to a portion of the truss assembly that is in ground contact. A gravitationally deployable restraining device, stored in and deployed from the container, includes sleeves, clips and keepers to deploy the restraining device to snare a vehicle.
The term “gravitationally deployable restraining device,” as used in this document, includes at least non-frangible open-meshed fabrics, nets, barriers, meshed materials, and sheets of material. The term “gravitationally deployable restraining device” also includes at least one cable intertwined with the gravitationally deployable restraining device. In one embodiment of the anti-vehicle security system, ends of the cable are connectable to two spaced-apart guides.
It will become apparent to one skilled in the art that the claimed subject matter as a whole, including the structure of the apparatus, and the cooperation of the elements of the apparatus, combine to result in a number of unexpected advantages and utilities. The structure and co-operation of structure of the anti-vehicle security system claimed in this document will become apparent to those skilled in the art when read in conjunction with the following description, drawing figures, and appended claims.
The foregoing has outlined broadly the more important features of the invention to better understand the detailed description that follows, and to better understand the contributions to the art. The anti-vehicle security system claimed in this document is not limited in application to the details of construction, and to the arrangements of the components, provided in the following description or drawing figures, but is capable of other embodiments, and of being practiced and carried out in various ways.

DETAILED DESCRIPTION
As shown in FIGS. 1–5, an anti-vehicle security system, generally designated 10, is provided that in its broadest context includes a truss assembly 12 formed with a plurality of monolithic stanchions 14; a container 16 fixed to truss assembly 12; two spaced-apart guides 18a,b extending from container 16 to a truss assembly member 20; a gravitationally deployable restraining device 22 that is removably insertable into container 16, and that also is connectable to two spaced-apart guides 18a,b; and also includes means 24 for deploying gravitationally deployable restraining device 22.
Anti-vehicle security system 10 includes no motor, no hydraulic apparatus, and no devices operable by alternating current.
The term “gravitationally deployable restraining device,” as used in this document, includes non-frangible open-meshed fabrics, nets, barriers, meshed materials, and sheets of material, generally designated 26, and referred to in this document for ease of reference as a “net.” The term “gravitationally deployable restraining device” also includes at least one cable 28 intertwined with gravitationally deployable restraining device 22. As shown by cross-reference between FIGS. 4B and 5, net 26′ is non-frangible.
In one embodiment of anti-vehicle security system 10, as shown by cross-reference between FIGS. 4A and 5, opposing ends 30a,b of cable 28 are connectable to two spaced-apart guides 18a,b. As perhaps best shown in the embodiment shown in FIGS. 1 and 3, spaced-apart guides 18a,b may be formed from cables 18a′ and 18b′. In one embodiment of anti-vehicle security system 10, as shown in FIGS. 1 and 4A, one or more sleeves 32a,b are provided. One or more sleeves 32a,b are connected to opposing ends 30a,b of cable 28 of gravitationally deployable restraining device 22. One or more sleeves 32a,b also are slideably mountable on two spaced-apart guides 18a,b. One or more sleeves 32a,b are weighted sufficiently to employ the force of gravity to remove the deployable restraining device 22 from the container 16 on opening of container 16.
As shown in FIG. 1, means 24 for deploying gravitationally deployable restraining device 22 also includes a plurality of ring clips 34a–n. Ring clips 34a–n are attachably detachable to gravitationally deployable restraining device 22. Ring clips 34a–n also are slideably engageable with the outer surface 34 of two spaced-apart guides 18a,b. As a person skilled in the art will appreciate, ring clips 34a–n may be selected from clips like parachute release clips used for connecting a military parachute to a static line. Ring clips 34a–n may be salvageable or of the break-away type.
In another embodiment of anti-vehicle security system 10, as perhaps best shown in FIGS. 1, means 24 for deploying gravitationally deployable restraining device 22 also includes a door 38. Door 38 is rotatably mounted on container 16. Door 38 includes opposing sides 40a,b (40b not shown) and opposing edges 42a,b. In one embodiment of anti-vehicle security system 10, opposing edge 42a is rotatably mounted on container 16 using a hinge assembly comparable to a piano hinge (not shown in detail). In another embodiment, door 38 is dimensioned along the longitudinal axis parallel to opposing edges 42a,b to be less than the dimension of container 16 to allow space for spaced-apart guides 18a,b to extend through a space (not shown) between opposing sides 40a,b and container 16. At least one latch 44 is included. Latch 44 may be attached to any number of means 46 for releasing latch 44. In one embodiment, as shown in FIG. 1, means 46 for releasing latch 44 is a lanyard 44′ extending from latch 44 to an operator of anti-vehicle security system 10. In another embodiment of anti-vehicle security system 10, means 46 for releasing latch 44 is a sensor-controlled remote control unit operated by battery (not shown).
As also shown by cross-reference between FIGS. 1 and 4A, anti-vehicle security system 10 includes in one embodiment a keeper 48. Keepers 48a,b are fixed to lower extremities 50a,b of two spaced-apart guides 18a,b. As shown, the term “lower” means in a direction opposite door 38 of container 16. Keepers 48a,b also are fixed to opposing ends 30a,b of cable 28.
As perhaps best shown in FIG. 1, anti-vehicle security system 10 includes in one embodiment means 52 for securing the anti-vehicle security system at a selected site. As shown, in one embodiment means 52 for securing the anti-vehicle security system at a selected site includes footer plates 54a–n. Footer plates 54a–n may be affixed to footings 56a–n as shown in FIG. 1. As will be evident to one skilled in the art, footer plates 54a–n may be affixed to footings 56a–n using any of a number of connectors well known in the art, including nuts and bolts 58a–n. 
Operation
In operation, as shown by cross-reference between FIGS. 1–5, anti-vehicle security system, generally designated 10, is secured at the entrance to a site into which vehicular traffic is prohibited. Footings 56a–n are formed from a material such a concrete, cured, and any of a number of connectors 58a–n are used to secure footer plates 54a–n to footings 56a–n, thus installing monolithic stanchions 14a–n of truss assembly 12 at a desired location. Container 16, with its rotatable door 38, has been mounted on truss assembly 12 as shown perhaps best in FIG. 1.
Restraining device 22 is attached to clips 34a–n that in turn are slidably mounted on spaced-apart guides 18a,b, as perhaps best shown in FIG. 4A. As indicated, restraining device 22 includes cable 28, opposing ends 30a,b of which are attached respectively to sleeves 32a–b and to keepers 48a,b. Much as one would pack a parachute, restraining device 22 may be packed into container 16. Door 38 is closed after restraining device 22 is packed into container 16, and latch 44 is secured.
Means 46, such as lanyard 46′, is attached to latch 44. The other end of lanyard 46′ is provided to an operator who is monitoring the secure site. When a suspicious vehicle seeks entry into the secure site, the operator may simply pull lanyard 46′. Door 38 swings open, and gravity pulls restraining device 22 from container 16. Gravity acts on sleeves 32a,b and on cable 28. In addition, opposing ends 30a,b of cable 28 are anchored to keepers 48a,b so that, in combination, cable 28 in restraining device 22 wraps around the motor vehicle A to preclude entry. Because none of the components need be frangible, restraining device 22 can be repacked and refolded into container 16 for reuse.
The anti-vehicle security system claimed in this document shows at least one embodiment in drawing FIGS. 1–5, but is not intended to be exclusive, but merely illustrative of the disclosed but non-exclusive embodiments. Claim elements and steps in this document have been numbered and/or lettered solely as an aid in readability and understanding. Claim elements and steps have been numbered solely as an aid in readability and understanding. The numbering is not intended to, and should not be considered as intending to, indicate the ordering of elements and steps in the claims.
