Description

Technical field

The invention relates to a mobile safety barric usable in transport.

BACKGROUND OF THE INVENTION

At present, heavy reinforced concrete barriers are used to similarly secure the space from unwanted, especially violent entry of heavy vehicles such as trucks, to prevent the vehicle from passing through by its weight, robustness and some stability. Their disadvantage is that they only apply to light trucks. These existing roadblocks will shorten or change the path of the stopped vehicle, but the heavier vehicles will break through and may continue to move along the original, unacceptably or arbitrarily long path.

Another disadvantage of the existing roadblocks is that they are heavy products manufactured by complex technology by a wet process and with low efficiency in preventing the passage of heavy vehicles. These disadvantages are at least partially eliminated by the mobile security roadblock of the invention.

SUMMARY OF THE INVENTION

The mobile safety roadblock comprises two lower arms, each lower arm being rigidly connected to a vertical arm, both lower arms being connected to each other by a lower strut and the two vertical arms being connected to each other by an upper strut, wherein at least one lower arm is at its end where connected to a vertical arm, provided with an overlapping bevel, the two lower arms being connected to each other by a lower stiffener, the connection of the lower arm and the vertical arm being reinforced by a wedge, characterized in that each vertical arm is rigidly connected to the upper arm.

A preferred mobile safety barricade, characterized in that at least one upper arm is provided with an overlapping bevel at its end where it is connected to the vertical arm.

Another advantageous mobile security roadblock characterized in that the two upper arms are connected to each other by an upper reinforcement.

The advantage of the mobile safety block according to the invention in its use lies in achieving high efficiency in stopping heavy vehicles or other mobile transport devices and thus preventing their violent unwanted passage.

The mobile safety block according to the invention, when applied, acts on a vehicle trying to forcibly enter the area protected by the mobile safety block according to the invention, so that when the vehicle hits the upper or vertical arm of the mobile safety block according to the invention The roadblock according to the invention lifts the front of the vehicle. This stops the vehicle because the front axle, as the drive axle of the vehicle, is in the air without contact with the road. Any further movement of the mobile safety block according to the invention with the demobilized vehicle raised is eliminated by friction between the vertical arms or tapered ends of the upper and lower arms of the mobile safety block according to the invention and the roadway.

The high efficiency of the mobile safety block according to the invention in stopping the vehicle is achieved by the geometric shape of the mobile safety block according to the invention, by the position

Utilizing the principle of the unequal arm together with the induced frictional force between the mobile safety roadblock according to the invention, loaded by the stopped car and the road surface or other surface on which the car moves.

When a traveling vehicle as a source of force acting on the lever arm strikes a mobile safety barrier according to the invention at the location of the vertical arm or face of the upper arm, it exerts its force on the vertical arms or upper arms and hence the lower arms which actuate the mobile safety block according to the invention in a rotational motion in the direction of travel of the vehicle about the axis of the mobile safety block parallel to the strut, thereby lifting the front part of the vehicle at least one lower arm and detaching it from the road if at least one lower arm is under the front of the vehicle. Thus, a raised vehicle can no longer move under its own power. The frictional force applied between the vertical arms or bevelled ends of the upper and lower arms of the rotated mobile safety barrier according to the invention and the road surface prevents further movement of the vehicle and stops it.

The mobile safety barrier according to the invention makes it possible, even with its subtle construction, to effectively prevent the forcible entry of vehicles into the space.

The mobile safety roadblock according to the invention is intended to be used to protect the defined area from forcible or accidental accidental passage of a heavy vehicle (truck) weighing up to 301.

The mobile security roadblock according to the invention is intended to be used for the protection of strategic objects, such as military facilities, ammunition depots, chemical depots, fuel and lubricant depots, power stations, airports, areas and areas where more people are gathered and need to be protected .

The mobile safety block according to the invention is lightweight, compact, highly efficient and affordable. Its production is simple and its appearance will have a positive aesthetic and unobtrusive impression on the surroundings.

DETAILED DESCRIPTION OF THE INVENTION

Example 1

The mobile safety barricade (see figures 1, 2, 3 and 4) consists of two lower arms 1, each lower arm 1 being rigidly connected to the vertical arm 2. Each vertical arm 2 is rigidly connected to the upper arm 3. The two lower arms 1 The two vertical arms 2 are connected to each other by the upper strut 6 and the two upper arms 3 can be connected to each other by the upper strut 7. The connection of the lower arms i and the vertical arms 2 can be reinforced by a welded wedge 8.

The lower arms 1 may be provided at their end, where they are connected to the vertical arm 2, with a chamfer that projects beyond the vertical arms 2. The chamfer may be directed downwards, i.e. in the basic position of the mobile security roadblock, to the ground or upwards or may be reversible. This arrangement improves the efficiency of the mobile roadblock in stopping heavy vehicles when attempting to pass.

The mobile safety roadblock in the basic position, seen from the side, see in particular Figure 3, has the shape of the long U-side with unequal long arms, i.e. two lower arms i, two vertical arms 2 and two upper arms 3. In this basic position the mobile safety barricade can be laid freely on the road when in use.

Technical data of mobile security roadblock:

Weight: approx. 350 kg

Dimensions: Vertical arm height 2: 0.90 to 1.10 m

Lower arm length 1: 1.5 to 1.8 m Upper arm length 3: 0.9 to 1.0 m Mobile safety bar width: 2 m

Material: welded steel frame of profile I 180 to 240, provided with protective coating of steel constructions, security hatching and marking, eventually plastic or other cladding. Possible accessories: flower pots, various color solutions, handles and holes for relocation.

Industrial applicability

The mobile safety block according to the invention is industrially useful for securing the defined area from unwanted, especially violent entry of heavy vehicles, eg trucks, into strategic objects, eg military buildings, ammunition depots, chemical warehouses, fuel and lubricant depots, power stations, airports and areas where more people gather and need to be protected.
