Title of invention:
A VEHICLE JAMMING BARRIER

CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY
The present application does not claim priority from any other patent application.
TECHNICAL FIELD
The present subject matter described herein, in general, relates to a field of vehicle barriers. More particularly, the present subject matter related to a vehicle jamming barrier.
BACKGROUND
Vehicle barriers are meant to stop, disable, or destroy vehicles intentionally driven into the perimeter of a protected area. These barriers may be active or static. The active barriers are actuated at the push of a button from a close position to open position whereas the static barriers have no inbuilt actuator and are already in vehicle-stopping posture.
Recent vehicle borne terror attacks show a trend of unauthorized trespassers with criminal intent driving their vehicles into overcrowded congregation and causing fatal damage and serious injuries to lives. As such congregations are often held at random locations, a temporary barrier system was envisaged that is mobile, easy to instal, static and yet can stop an intruding vehicle effectively.
There are a variety of vehicle barriers available in the market, but these vehicle barriers are either not mobile or if mobile they are not strong enough to incapacitate a high-speed heavy vehicle. Moreover, the existing vehicle barriers cannot stop the vehicle without flipping of the vehicle barriers. The joints of the vehicle barriers break due to impact of the over-speeding vehicle and tend to be less durable and ineffective.
Thus, there is a long-standing need for an improved vehicle jamming barrier that alleviates the afore mentioned technical challenges/drawbacks and provide a credible solution for saving lives of innocent bystanders from a vehicle borne terror attack.

DETAILED DESCRIPTION

Reference throughout the specification to “various embodiments,” “some embodiments,” “one embodiment,” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of the phrases “in various embodiments,” “in some embodiments,” “in one embodiment,” or “in an embodiment” in places throughout the specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner in one or more embodiments.

Figure 1 illustrates a vehicle jamming barrier 100, in accordance with an embodiment of a present subject matter. In one embodiment, the vehicle jamming barrier 100 may comprise a set of L-shaped channels 101. The set of L-shaped channels 101 may comprise one or more a subset of L-shaped channels 101-1, 101-2. In one embodiment, two neighbouring subset of L-shaped channels 101-1, 101-2 may be linked together with one or more chains 105.
Furthermore, the vehicle jamming barrier 100 may comprise clearance fit 102 which may join a set of links 401 as shown in figure 4a. In an embodiment, the vehicle jamming barrier 100 may rotate in a rotating axis 104 when an over-speeding vehicle may crash on said vehicle jamming barrier 100.
Referring to figure 2, illustrates L-shaped channel 200 of the vehicle jamming barrier 100, in accordance with an embodiment of a present subject matter. In one embodiment, each L-shaped channel 200 may comprise a horizontal channel 202 and a vertical channel 201, wherein the horizontal channel 202 is parallel to the road surface and vertical channel 201 substantially perpendicular to the road surface. The L-shaped channel 200 may comprise a connecting bar 203 configured to connect the vertical channel 201 and the horizontal channel 202. In one embodiment, the connecting bar 203 may form a substantially perpendicular angle between the vertical channel 201 and the horizontal channel 202. The L-shaped channel 200 may further comprise a plurality of anchors such as top anchors 204 and bottom anchors 205 which may be disposed on extreme ends of the vertical channel 201 and the horizontal channel 202 respectively. In one embodiment, the plurality of anchors 204, 205 may comprise protruding spikes on either side of a top edge surface of the vertical channel 201 and a joining edge surface of the horizontal channel 202. The protruding spikes may facilitate in stabilizing the L-shaped channel 200 on the ground and puncturing the tires of the over-speeding vehicle. The L-shaped channel 200 may comprise one or more fulcrum pins 206 for joining the connecting bar 203 with the vertical channel 201 and the horizontal channel 202.
In one embodiment, each subset of channels 101-1, 101-2 may comprise two or more L-shaped channels 200 arranged parallel to each other and deployed on a road surface.

Figure 3a illustrates an enlarged view of chains 105 fixed vertically and figure 3b illustrates an enlarged view of chains 105 fixed horizontally, in accordance with an embodiment of a present subject matter. In one embodiment, the chains 105 may be linked between each of the subset of L-shaped channels 101-1, 101-2. The chains 105 may link adjacent vertical channels 201 of at least two adjacent subsets of L-shaped channels 101-1, 101-2. Similarly, the chains 105 may also link each of adjacent horizontal channels 202 of at least two adjacent subsets of L-shaped channels 101-1, 101-2.

Figure 3c illustrates an enlarged view of the clearance fit 102, in accordance with an embodiment of a present subject matter.

Figure 4a illustrates a subset of L-shaped channels 101-1 and figure 4b illustrates an enlarged view of clearance fit 102, in accordance with an embodiment of a present subject matter. In one embodiment, a set of links 401 may connect each pair of adjacent L-shaped channels 200. The set of links 401 may loosely couple the two adjacent L-shaped channels 200 by the clearance fit 102. A gap 402 in the clearance fit 102 is seen in figure 4b which allows the loose coupling of the two adjacent L-shaped channels 200 using the set of links 401. The gap 402 may have predefined minimum tolerance which provides flexible movement of the clearance fit 102. When the vehicle collides with the L-shaped channels, the gap 402 allows limited movement of the set of links 401 thereby resulting into transfer of differential momentum between neighbouring L-shaped channel. If the L-shaped channels are rigidly connected using the set of links 401, it may result into breaking of the L-shaped channels after impact. On the other hand, if the L-shaped channels are connected very loosely, the differential momentum might not be transferred to the extreme L-shaped channels. Thus, the gap 402 between the L-shaped channels and the nut-bolts on the set of links 401 is maintained between 2mm to 5mm depending on the dimensions of the L-shaped channels. In an exemplary embodiment, when the over-speeding vehicle may crash on the vehicle jamming barrier 100, the plurality of bottom anchors 205 of the L-shaped channel 200 may cause the sets of L-shaped channels 101 to cling to the ground or road via protruding spikes, when the vehicle may come over the horizontal channels 202 of the L-shaped channels 200. The impact of the vehicle may occur on vertical channels 201 of the L-shaped channels 200. The plurality of top anchors 204 may be configured to puncture the front tires of vehicle through the protruding spikes. Once the vehicle crashes on the vehicle jamming barrier 100, the set of links 401 transfer the differential momentum to the adjacent links 401. As the clearance fit 102 loosely couples the two adjacent L-shaped channels 200, the transfer of differential momentum from one subset of L-shaped channels 101-1 to other subset of L-shaped channel 101-2 takes place. Due to such transfer of differential momentum, the vehicle jamming barrier 100 may not break rather set the L-shaped channel into circular motion and distribute the load equally across the L-shaped channel. The clearance fit 102 may be a flexible part and provides flexible movement of the set of links 401. Such flexible movement of the clearance fit 102 enables the vehicle jamming barrier 100 to grab the over-speeding vehicle thereby completely stopping the over-speeding vehicle by the vehicle jamming barrier 100.

Figure 5a illustrates linking 501 for chains 103 of the vehicle jamming barrier 100 and figure 5b illustrates enlarged view of the linking 501, accordance with the embodiment of the present subject matter. In one embodiment, the linking 501 may be, but may not be limited to, round shaped rings through which the chains 103 may be joined by using screws, nuts and bolts. In one embodiment, the one or more chains 103 may be high tensile flexible chains.

The vehicle jamming barrier 100 may be portable, durable and easy to assemble. The vehicle jamming barrier 100 may be made of metal or such like.
