RELATED APPLICATION
The present utility patent application is based upon U.S. Provisional Patent Application Ser. No. 60/103,872, filed on Oct. 13, 1998, and entitled “VEHICLE STOPPING DEVICE”.
TECHNICAL FIELD
The present invention relates to law enforcement equipment. More particularly, the present invention relates to non-lethal devices employed by police agencies on a roadway during pursuit to safely and almost instantly stop a fleeing vehicle.
BACKGROUND ART
As is perhaps well known, there have recently been several notorious chases of fleeing vehicles whose drivers refuse to stop or try to outrun the police. Some of the most famous chases involved armed and dangerous criminals who had virtually nothing to lose by using their vehicle to crash through classic police roadblocks which often resulted in bodily injury and great property damage.
The classic police roadblock by which police cars are parked across a roadway results in blockage of all vehicular traffic and thereby often causes congestion of citizen drivers at the roadblock who must either be allowed to pass by movement of police cars or risk physical harm in any subsequent confrontation between the police and the driver of a fleeing vehicle. In other words, classic police roadblocks are non-selective, cause congestion and often result in more injury than they are worth.
Accordingly, the prior art reveals attempts to replace classic police roadblocks with a selective and safe means for stopping a fleeing vehicle by puncturing its tires. A preferred device in use today is known as a spike strip and there are several variations, none of which have the advantages of the present invention. One of the earlier known spike strips simply consisted of a narrow length of flat rubber or fabric base containing a multitude of nails oriented in the same direction so that the strip could be coiled for storage in a trunk of a police car, but upon approach of a fleeing vehicle, the coil could be rolled across a roadway in the path of the vehicle whereby the nails would puncture the tires. However, in practice, it soon became apparent that a coil of nails had several inherent problems. First, the nails often snagged upon each other as the coil was unwound and often ensnared itself on other items. Secondly, someone had to physically place the outstretched strip with nails upright in the path of an oncoming vehicle which was usually driven at a very high speed, thereby allowing a few seconds to complete the task. Thirdly, even when initial contact is made between the strip and the fleeing vehicle, it was often seen that solid nails alone did not deflate the tires rapidly enough and the vehicle would continue for several more miles before being disabled. Fourthly, this type of coiled spike strip was non-selective in that any innocent vehicle ahead of the fleeing vehicle on the same roadway would obviously contact the nails and thereby most often result in the entire strip being adhered to the tires and dislodged from the roadway.
In the past, various patents have issued relating to devices for the rapid stopping of vehicles. For example, U.S. Pat. No. 4,382,714, issued on May 10, 1983 to W. G. Hutchison, describes a vehicle disabling device in the form of a plurality of spike-like devices adapted to project perpendicular to a road surface to puncture one or more tires of a fleeing vehicle. A plurality of the devices are interconnected for ease in putting in place and removing as well as creating a flailing effect when engaged.
U.S. Pat. No. 4,544,303, issued on Oct. 1, 1985 to F. G. Glasmire, describes a protective traffic barrier designed to divert motor vehicle traffic away from an object or roadway. This device employs a base with wedge-shaped projections extending vertically from the base so as to impede the movement of a motor vehicle across the barrier. The shape of the base may be designed to fulfill a particular function including an opening to allow the barrier to fit over an object to be protected. A resilient cover encapsulates the base so as to protect people or animals from contact injury with the wedge-shaped projections.
U.S. Pat. No. 5,123,774, issued on Jun. 23, 1992 to J. J. Dubiel, teaches an apparatus for the puncturing of tires. This apparatus employs a plurality of spaced tubular supports which are secured together by a flexible tether line. The respective outer distal tubular support members include a respective outer tether line that is in turn secured to a spike member for projection into the ground surface on opposed sides of a highway structure. Plural pairs of spaced parallel spikes define an acute angle therebetween.
U.S. Pat. No. 5,322,385, issued on Jun. 21, 1994 to R. Reisman, describes an anti-vehicle barrier that includes a pad made of a compressible material. An array of upwardly directed hollow metal spikes are distributed throughout the pad so as to puncture the tire of a vehicle which rides over the pad. The spikes may be removable so that upon puncturing the tire, they are removed from the pad and retained by the punctured tire so as to bring about its rapid deflation. When deployed in the pad, the spikes are flush with or are below the top surface of the pad.
U.S. Pat. No. 5,328,292, issued on Jul. 12, 1994 to F. R. Williams, teaches a traffic barrier which gives law-enforcement officers an effective traffic barrier which can be easily carried in the trunk of a car and quickly deployed across a roadway. The chain is simply stretched across the roadway at a right angle to the direction of traffic and pulled tight. The traffic barrier chain is designed so that no matter how the chain is placed on the road surface, half of the splines will be facing the direction of traffic flow at an angle of 45 degrees.
U.S. Pat. No. 5,498,102, issued on Mar. 12, 1996 to S. Bissell, teaches a tire puncturing spike strip which can be placed on a road surface in front of a moving vehicle. The spike strip is composed of rectangular modular frame units with low height for easy storage in a trunk of a police vehicle. The frame units have interlocking ends which can be quickly assembled in any desired length for placement across a roadway with spikes in a normal down position to allow safe passage of vehicles over the strip. The spikes may be selectively and remotely activated to their up position electromechanically by an operator to target a specific fleeing vehicle. Once the fleeing vehicle crosses over the strip, the spikes may be electromechanically returned to their down position to allow pursuing police cars to safely cross over the strip and apprehend the disabled vehicle.
It is an object of the present invention to provide a vehicle stopping device which rapidly brakes the fleeing vehicle.
It is another object of the present invention to provide a vehicle stopping device which is capable of selective deployment.
It is another object of the present invention to provide a vehicle stopping device which serves to stop both large and small vehicles.
It is another object of the present invention to provide a vehicle stopping device which can be folded so as to be easily stored in the trunk of a law enforcement vehicle.
It is a further object of the present invention to provide a vehicle stopping device which can be deployed by a single person.
It is still another object of the present invention to provide a vehicle stopping device which is easy to use, easy to manufacture and relatively inexpensive.
These and other objects and advantages of the present invention will become apparent from a reading of the attached specification and appended claims.
SUMMARY OF THE INVENTION
The present invention is a vehicle stopping device having a panel of material which has a tactile leading edge. The panel of material has a size which, when unfolded, has a width suitable for extending across a roadway. The panel of material can be suitably folded, when not in use, into a concertina.
In the present invention, a split seam extends longitudinally across the panel of material from the leading edge. The split seam extends approximately three quarters of the length of the unfolded length of the panel of material. This split seam splits the panel in half and is located in a middle of the unfolded panel. The panel of material is formed of a light weight material, such as silk.
A reinforcement sash is affixed to the panel of material. This reinforcement sash is formed of a strong flexible material, such as KEVLAR (?). One end of the reinforcement sash is attached to the leading edge and extends in parallel relationship to the split seam toward the rearward end of the panel. The reinforcement sash loops around the end of the split seam so as to extend toward the other side of the panel of material. This reinforcement sash then extends toward the leading edge on the opposite side of the split seam. A V-shaped connector serves to connect the reinforcement sash along the leading edge of the panel.
The tactile leading edge extends along the leading edge of the panel of material widthwise across the panel. This tactile leading edge is formed on both sides of the split seam. The tactile leading edge includes an adhesive blister formed there across. Barbed pins can also be provided on this tactile leading edge so as to allow for the secure engagement with the tire of a fleeing vehicle. In the preferred embodiment of the present invention, a plurality of adhesive blisters extend in a row across the length of the tactile leading edge. The plurality of barbs are positioned between adjacent adhesive blisters.
In use, the panel of material is deployed with the tactile leading edge facing the approaching vehicle. When the vehicle advances, the front tires of the approaching vehicle will contact the tactile leading edge so as to bond the leading edge to the tire. As the vehicle continues, the wheels will rotate so as to wrap the panel of material, and its associated reinforcement sash, around the wheels. When the panel reaches the limits of the split, a tight restricting action will occur on the wheels of the vehicle so as to cause an immediate braking force.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1, there is shown at?10?the vehicle stopping device in accordance with the teachings of the present invention. The vehicle stopping device?10?includes a panel of material?12?having a tactile leading edge?14. A split seam?16extends longitudinally across the panel?12?for less than the length of the panel?12. A reinforcement sash?18?extends from the leading edge?14?on one side of the split seam?16, loops around the end?20?of the split seam?16, and returns back to the leading edge?14?on the opposite side of split seam?16.
As can be seen in FIG. 1, the panel of material?12?has a rectangular configuration. This panel of material should be of a very light weight fabric, such as silk. The panel?12?can be folded along fold lines?22?and across the split seam?16?so as to reside in a concertina folded arrangement. As such, the panel?12?can be easily stored in the trunk of a law enforcement vehicle. The panel?12?should have an unfolded width that is suitable for extending across a roadway. In the preferred embodiment of the present invention, the unfolded panel will have a width suitable for extending across a single lane. In the preferred embodiment of the present invention, the panel?12?will be approximately eighteen feet long.
The tactile leading edge?14?is located at one end of the panel?12. The tactile leading edge?14?extends from side?24?to side?26of the panel?12. The leading edge?14?is located on both sides of the split seam?16. A V-shaped noticed notch?28?will extend from the leading edge?14?toward the split seam?16. As will be described hereinafter, the tactile leading edge?14?can include barbed pins extending upwardly therefrom and/or adhesive blisters extending there across. The tactile leading edge?14?will extend widthwise across the panel?12.
The split seam?16, in the preferred embodiment, will extend approximately three-quarters of the length of the unfolded panel12. The split seam?16?will terminate at end?20?inwardly from the rear end?30?of the panel?12. The split seam?16?is actually split or is weakly held together. The split seam?16?extends longitudinally through the middle of the panel?12.
The reinforcement sash?18?has a particular configuration so as to allow the device?10?to effectively brake a fleeing vehicle. The reinforcement sash?18?should be of a strong flexible material, such as KEVLAR (?). The reinforcement sash?18?should be affixed to the surface of the panel?12. One end?32?of the reinforcement sash?18?is affixed to the leading edge?14?on one side of the split seam?16. The reinforcement sash?18?specifically has a V-shaped configuration?34?at the leading edge?14. The wide end of the V-shaped configuration?34?is affixed to the leading edge?14?such that one leg of the V-shaped configuration is adjacent to the split seam?16?and the opposite leg will be adjacent to the side?26?of panel?12. Each of the legs of the V-shaped configuration converge together in a central area?36?which extends lengthwise across the panel?12along one side of the split seam?16. The reinforcement sash?18?has a looped section?38?which will extend around the end?20of the split seam?16?so as to emerge on the opposite side of the split seam. It can be seen that the opposite side of the split seam also has the reinforcement sash?18?with a V-shaped section?40. The V-shaped section?40?has a first leg?42?adjacent to the side?24?of panel?12?and an opposite leg?44?adjacent to the split seam?16. Each of the legs?42?and?44?are affixed to the leading edge?14. The legs?42?and?44?converge together to the linear portion?46. The reinforcement sash?18?should be integrally formed together.
FIG. 2 shows the arrangement of the leading edge?14. As can be seen, the leading edge?14?has a plurality of adhesive blisters?50?extending upwardly from the surface of panel?12. Barbed pins?52?also extend upwardly from the panel?12?between adjacent pairs of adhesive blisters. It is important to note that, in the present invention, the barbs?52?and the blisters?50?can be arranged in any desired pattern. However, in the preferred embodiment of the present invention, the barbs?52?will be positioned between adjacent pairs of adhesive blisters.
FIG. 3 shows the circled area?54?of FIG.?2. As can be seen, the barbed pin?52?extends upwardly between an adhesive blister?60?and another adhesive blister?62. When a tire rolls over the leading edge?14, the barbed pin?52?will engage the tire of the vehicle. Simultaneously, the adhesive blisters?60?and?62?will break open so as to apply a fast-drying adhesive between the panel?12?and the surface of a tire. As such, the present invention provides a two-way manner of connecting the leading edge?14?to the surface of the tire.
FIG. 4 shows the manner in which the device?10?can be applied to a surface?70?of a roadway?72. As can be seen, the panel12?is unfolded into a flat condition. The leading edge?14?is deployed so as to be facing the approaching vehicle. The panel?12will stretch flat across the surface?70?of the roadway?72.
FIG. 5 shows a vehicle?76?approaching the device?10?of the present invention. As can be seen, the front wheels?78?and?80of the vehicle?76?are approaching the leading edge?14?of the panel?12. As such, the wheels?78?and?80?are in a suitable position for engaging the tactile leading edge?14. As the vehicle?76?travels onto the leading edge?14, the barbs?52?and the adhesive blisters?50?will act so as to strongly adhere to the wheels?78?and?80. The remaining panel?12?will wrap around the wheels of vehicle?76.
As can be seen in FIG. 6, the device?10?is shown as wrapping around the wheel?80?of the vehicle. The opposite side of the panel will wrap around the wheel?78. As a result, the panel?12, and its associated reinforcement sash?18, will be drawn into the vehicle. The vehicle?76, as illustrated in FIG. 6, is a relatively large vehicle with a long wheelbase. The device?10?will be drawn up under the chassis area. When the system?10?reaches the limits of the split?16, the reinforcement sash will be drawn tight so as to restrict rotation of the wheels and thus cause an immediate braking force.
FIG. 7 shows a smaller vehicle?90?encountering the device?10. When a smaller vehicle with a shorter wheelbase contacts the device?10, the leading edge?14?will be drawn around the front wheels in a similar fashion as described hereinbefore. However, the rear wheels?92?will contact the rearward edge?30?of the panel of material?12?before the wrapping effect is fully achieved. As a result, the actual action of the rear wheels?92?will cause the leading edge?14?to cause a braking action on the vehicle. The leading edge will wrap around the front wheel?94?until such time as the wrapping is prevented by contact between the rear wheel?92?and the surface of the panel?12. As such, the front wheel?94?will be prevented from further rotation. The vehicle will come to an immediate stop.
The foregoing disclosure and description of the invention is illustrative and explanatory thereof. Various changes in the details of the illustrated construction may be made within the scope of the appended claims without departing from the true spirit of the invention. The present invention should only be limited by the following claims and their legal equivalents.
