Description

The invention relates to technical means of road safety, and in particular to devices for blocking motor vehicles moving in violation of the rules and posing a security risk to other road users.

Known roadblocks of motor vehicles.

So, the protector according to US Pat. US No. 17061, 1929, consists of a plurality of planks joined by the principle of the Nuremberg scissors, with removable spikes mounted on them. If necessary, a forced stop of motor vehicles, the trap is manually pushed and set across the road lane with spikes up.

A disadvantage of the known analogue is the relatively large time required for its installation.

Also known device-protector against motor vehicles according to US Pat. RF № 2062431, 1996, IPC RF № 2062431, 1996, IPC F41H 11/08. The device consists of a folding fence, made in the form of an N-link articulated mechanism. Each link is made in the form of two intersecting plates pivotally connected to each other at the intersection points and at the ends. Damage elements in the form of spikes are installed on the hinge axes. When folded, the boom is placed on a bed to which a one-bottom cylinder is attached with a piston installed in it with a drain protruding from the open end of the cylinder. The end of the boom is connected to the stem. The volume of the cylinder formed between its bottom and the piston is communicated through an opening made at the bottom of the cylinder with a source of compressed gas.

A well-known analogue allows to reduce the time required to bring the trap into working position.

The disadvantage of this analogue is its relatively low reliability, due to the need to use a source of compressed gas. In real road conditions, with the possible impact on the device of hydrometeors (rain, snow, moisture, etc.), the source of compressed gas may be inoperative.

The closest in its technical essence to the claimed is a known trap against motor vehicles according to the patent of the Russian Federation No. 2309218 dated 10.27.2007 IPC F41H 11/08.

The closest analogue consists of N pairs of intersecting plates, striking elements in the form of removable spikes and a box in which the plates are placed in a folded position. The plates of each pair are pivotally connected to each other at their centers, and their ends are pivotally connected to the ends of the plates belonging to adjacent pairs of plates. The striking elements are mounted on the hinge axes. N pairs of crossed plates when folded are placed on the bed.

On the hinge axes located in the centers of the plates, springs are installed between the plates to ensure the deployment of the plates. The first pair of plates is fixed in a box provided with a latch that holds the plates in the folded state and an unlocking element of the latch.

Due to the distributed application of deployment forces and the placement of the plates in a folded position in a closed box, reliable deployment of the device is ensured.

The disadvantage of the closest analogue is the lack of regulation and strict fixation of the deployment length, which in some cases can lead to device breakdown in cases of road width less than the device length in the working position, or to unreliable blocking in cases of road width more than the device length in working position.

The technical result achieved by using the claimed trap is to reduce the likelihood of breakdown and increase the reliability of blocking motor vehicles by fixing the maximum length of the trap in the unfolded position, as well as the possibility of changing this fixed maximum length.

The claimed device extends the arsenal of funds for this purpose.

The specified technical result is achieved by the fact that in the known protector against motor vehicles containing N pairs of intersecting plates (PP), striking elements (PE) and a box in which PP are placed in a collapsed position, the PP of each pair is pivotally connected to the ends of the PP belonging to adjacent pairs PP, PE are installed on the hinge axes, and on the hinge axes located in the centers of the PP, springs are installed between them to ensure the deployment of the PP, and the first pair of PP is fixed in the box, equipped with a latch that holds the PP in in the box and the release element of the lock, in addition between the ends of the adjacent pairs of PP, pivotally limiters for the deployment length of the trap (ODRZ) are fixed.

Each ODRZ is made of two plates, the ends of which adjoining each other are hinged. The peripheral ends of the plates ODRZ pivotally mounted on the respective ends of adjacent to each other pairs of PP.

The length d of each of the ODRZ plates is selected in the interval d = (0.2 ÷ 0.45) D, where D is half the length of one of the PPs. The total number M ODRZ selected in the range 2≤M≤N-1.

The striking elements are made in the form of removable spikes.

The listed new set of features due to the introduced ODRZ, and the possibility of changing their sizes allows you to set a fixed length of the trap in the unfolded position, which reduces the likelihood of breakdown of the trap and increases the reliability of blocking vehicles.

The claimed device is illustrated by drawings, where

figure 1 - the device is folded (top view);

figure 2 is a cross-sectional view of the device;

figure 3 - the device is folded (side view is a section along the longitudinal axis);

figure 4 - the device in the expanded state (top view - fragment);

figure 5 - striking element.

The anti-motorized choke, shown in figures 1-3, consists of a box 1, with dimensions L × T × H, a set of N pairs of PP 2, which in a collapsed position are located in the cavity of the box 1 (figure 1), PE 3, mounted on the axes of the hinges 4, and ODRZ, pivotally mounted between the ends of adjacent to each other pairs of PP2.

Each ODRZ is made of two plates 5, 5 ', the ends of which adjoining each other are pivotally connected (axis "a", figure 2). The peripheral ends of the plates 5.5 ′ ODRZ are pivotally mounted on the corresponding ends of the adjacent pairs of PP 2 (axis “b”). Plate 5, 5 ′ ODRZ installed between the respective PP 2 (see figure 2).

The first pair of PP 2 is fastened, for example, by means of a strip 6 with the rear end wall of the box 1. The plate 6 is rigidly fastened with the rear end wall of the box 1, and it is pivotally with the first pair of PP 2, for example, by installing the strip 6 on the axis of the hinge of the first pair PP 2 (axis "in" in figure 1).

The lower edge of the front end wall 7 of the box 1 is pivotally connected to the lower edge of the bottom of the box 1. In the collapsed position, the PP 2 are located in the cavity of the box 1 and are held in this position by the end wall 7, which in turn is held closed by the lock 8.

The embodiment of the latch shown in figure 3 is similar to the design of the latch described in the closest analogue (US Pat. RF No. 2309218, figure 2).

PE 3 can be installed on the axes of the hinges 4 both in the centers of the PP 2 and at their ends. PE 3 made in the form of removable spikes (figure 5), using a threaded connection mounted on the axis of the hinge 4.

In each pair of PP 2, a spring 9 is installed on the hinge axis in the place of their intersection between the plates, which ensures the deployment of the plates when the lock 8 is released.

The claimed device operates as follows.

In the initial state, all pairs of PP 2 are pulled close to each other, installed in the cavity of the duct 1 and are held in this position by the end wall 7 of the duct 1. In turn, the end wall 7 is held in the closed position by the latch 8. Also, the plates 5 are in the folded state 5 'ODRZ (figure 1, 2).

If you need to deploy the device, the lock is unlocked. Under the action of the elastic forces of the springs 9, the deployment of all pairs of PP 2 occurs. In this case, the deployment forces of all the springs 9 add up and mutually reserve each other.

Simultaneously with the deployment of PP 2, the deployment of ODRZ is occurring. Moreover, the total length of the trap in the deployed position will be determined by the length 2d ODRZ in the deployed position (figure 4). By varying the length of 2d ODRZ, you can pre-set the final total length of the trap. Based on the design of the ODRF, the length d of each of its plates 5, 5 'should be selected not exceeding half the length D of one of the PP 2.

For a given number of pairs N PP 2 and their length 2D, a specific value of d is selected based on the width of the roadway, which must be covered. The number M of pairs of ODRZ, established between the respective adjacent pairs of PP 2, can be selected in the range 2≤M≤N-1.

In the expanded position, the PP 2 lie across the road lane with the spikes up.

The suppressor can be installed covertly in places at the intersection of which the intruder no longer expects any active actions to block his vehicle. Bringing the trap into working position can be carried out remotely. The latch 8 can be unlocked, for example, by radio.

For reliable "dropping" the end wall, the plane of the bottom of the box 1 must be installed above the ground at a small angle α = 5-10 °, which is achieved by the stand 10, mounted in front of the bottom of the box 1 (Fig.3).

The number N of pairs of PP 2, their length 2D and the length d of the plates 5, 5 'ODRZ choose based on the required length of the trap in the deployed position.

The dimensions L × T × H of the box 1 are selected from the condition of free placement of all PP 2 in it in a collapsed position and taking into account the height of PE 3.

For example, with a width t of PP 2 equal to t = 5 cm and their length 2D = 100 cm, N = 10, height PE 3 equal to 10 cm, the dimensions of the duct can be N = 20 cm, T = 100 cm, L = 55 cm.

With the indicated dimensions, the length of the trap in the working position will depend on the length d of the plates 5, 5 ′ ODRZ.

So, at d = 0.4 m, the length of the trap in the deployed position will be about 8 m, and at d = 0.25 m, the length of the trap in the deployed position will be 5 m.

Installation (replacement) of the ODRZ of the required length is carried out by removing the corresponding hinges (axis “b” in FIG. 2), securing the ends of the plates 5, 5 'of the ODRZ on them and reinstalling the hinges in their original place.

Thus, in the inventive device, by choosing a fixed deployment length by installing limiters for the deployment length of the trap, the probability of breakdown is reduced and there is an increase in the reliability of blocking motor vehicles in various road conditions, i.e. the achievement of the formulated technical result is ensured.
