[0002] A mechanism to counteract the unauthorized entry of a wheeled vehicle into a protected area by destroying the transmission and critical components of the invading vehicle.

[0008] The well-known ROAD BLOCKER device is designed to forcibly stop a vehicle by raising the platform at an angle to the vehicle. This type of road blocker is based on the barrier principle; the blocker must first be operational.

[0009] The V-08 and V-011 impact-activated road blockers work in conjunction with special swing double-leaf anti-ram gates of the V-14 or V-2 type (catalog link: https: / / www.valeev24.ru / application / rapid / main / documents / 27_katalog-mini-valeev-protivotarannyie-sistemyi-pdf.pdf). The device is activated immediately upon an attempt to ram the gate. Until the gate is rammed, the blocker remains dormant, remaining fully operational. The device is compactly located; its underground installation does not interfere with vehicle access. Its components are not subject to impact when entering the protected area through the gate opening. Consequently, there are no axle load restrictions, unlike similar devices.

[0010] A key difference from similar devices is the activation of the V-08 and V-011 road blockers after an attempt to ram the entrance gate. This simple mechanical activation method is independent of any dependencies: security personnel's reaction to the activation / raising of the platform, similar to similar devices, or electrical power. The V-08 and V-011 impact-activated road blockers are located within the protected area, simplifying maintenance and eliminating any sabotage that could disable the device. Another important difference from similar devices is the device's location and activation perpendicular to the vehicle's axis. The main destructive / blocking element, the "spike," acts like a knife, ripping open critical vehicle components (transmission, transfer case, engine). The vehicle's weight impinges on the extended spike, causing it to self-destruct. Unlike similar devices, this device exerts a pinpoint impact on the area within the vehicle attempting to break through, counteracting the impact with its entire weight and the mass of the concrete foundation.The V-011 impact road blocker differs from the V-08 in its more reinforced design (the weight of the stopped vehicle is no more than 11 tons, at a vehicle speed of no more than 60 km / h).

[0011] Operating diagram of the impact-activated road blocker with double-leaf swing anti-ram gates of the V-14 and V-2 types: the operating zone opens outward. When an attempt is made to force the gate by pushing inward, the lifting mechanism of the impact-activated road blocker is activated. The force exerted on the gate is transmitted from the gate leaves to the movable "rod," which then shears the safety aluminum pin and shifts the safety plate, releasing the device's "spike," while simultaneously acting on the impact lug to accelerate the "spike"'s lifting. The "spike," under the influence of the "rod" and its own counterweights, locks the gate.The speed of pressure on the gate does not have a special effect on the speed of lifting the "spike" (regulated by counterweights), however, the greater the speed of the vehicle attacking the gate, the harder the "bar" from the gate leaves will hit the striking protrusion and the faster the "spike" will move into the position blocking passage, thereby eliminating the possibility of "slipping through" the road blocker at higher speeds (dependency: the greater the speed of the vehicle, the faster the road blocker will operate).

[0012] This device was developed based on eighteen years of practical experience and real-world needs, and is a logical continuation of the development of technical means in this field. It is the "last line" in preventing wheeled vehicles from entering a secure area. Due to its compact size, it is recommended for installation in all types of educational institutions and preschools, as well as for public organizations of all types, as a reinforcement for V-14 and V-2 double-leaf anti-ram gates. The blocker requires no ongoing maintenance, no electrical wiring, and is safe for people (due to its design, it prevents pinching of limbs, falling into technical cavities, etc.).

[0016] The image shows a road blocker with an impact activation, where in a steel housing (1) on an axis (2) there is a retractable spike (8), with counterweights (7) installed on it and a covering anti-skid plate (9). The spike locking mechanism (6) holds the spike in the "open" position. At the moment of impact, the safety plate (3) releases the spike (8), which, under the influence of gravity, reinforced by the counterweights (7), gets into the vehicle blocking position. The safety plate (3) additionally accelerates the spike (8), acting on the impact protrusion (4). The axis reinforcement plates (5) compensate for the impact load, preventing the housing (1) from being destroyed at the attachment point of the spike axis (2). Bolted connections (11) throughout the housing (1) provide additional rigidity to the geometry of the welded structure of the housing.

[0023] Disclosure of the utility model essence: this mechanism increases the level of anti-ram safety even when installing "lightweight" anti-ram swing double-leaf gates. For example, the stopping capacity of the V-2 anti-ram swing double-leaf gate is only two tons (at vehicle speeds of up to 60 km / h), but when installed with the V-08 impact-activated road blocker, the stopping capacity of the entry group increases to 10 tons (at vehicle speeds of up to 60 km / h).

[0024] Advantages of the invention: The impact-activated road blocker significantly increases security against unauthorized vehicles entering a protected area, while having a compact design and a simple activation system independent of other factors (electricity, etc.). The impact-activated road blocker is easy to maintain and safe for others.
