The present patent application for industrial invention relates to a self-propelled security road barrier used to protect public places from the risk of terrorism attacks with motor vehicles launched at high speed.
Recently, terrorism attacks made with motor vehicles that run into the crowd at high speed have become more and more frequent, with the intention of making as many victims as possible. In view of these events, public authorities have attempted to protect public places by creating obstacles capable of preventing the free access of motor vehicles to pedestrian areas.
Given the limited experience of public authorities on this specific dangerous situation, the protection measures that have been applied so far have proved to be quite ineffective. In fact, in some cases, the access to a street or a square has been protected with simple concrete blocks or with big heavy flower boxes. Because of their dimensions and especially because of their weight, these objects create an effective security road barrier against heavy motor vehicles. However, the dimensions and the weight of these objects are a significant functional limitation because they are difficult to install and remove.
A problem is encountered when the access to a public place is closed by means of such an object, because said object cannot be rapidly and easily removed as necessary to permit the passage of an “ordinary” emergency vehicle, such as an ambulance or a fire brigade truck.
Also for this reason, an alternative solution has been used in other cases, in order to create a security road barrier that is capable of being rapidly removed from the installation place, if necessary.
Such a solution consists in closing the access to sensitive places by means of big trucks, especially building trucks loaded with crushed stone or other heavy inert materials. Alternatively, military means of transportation, such as light-armored cars or tanks, can be used.
Being very big, these trucks are capable of withstanding and reducing the shock of vehicles, including heavy ones, launched at high speed against them.
An advantage of this solution is the fact that these trucks can be moved easily, if necessary, to immediately free a point of access to a street or a square.
However, such a solution is impaired by the fact that the presence of big trucks in a town center or in a pedestrian area is unpleasant to see.
The purpose of the present invention is to overcome the drawbacks of the prior art, by devising a self-propelled security road barrier that can resist violent shocks and can be autonomously moved easily and rapidly from the place where it is positioned.
Another purpose of the present invention is to disclose a security road barrier that can be easily moved and at the same time is aesthetically pleasant, in such a way as to improve the general appearance of the public place where it is to be installed.
These purposes are achieved according to the invention with the characteristics of the appended independent claim 1.
Advantageous embodiments appear from the dependent claims.
The security road barrier of the invention is defined by claim 1.
The advantages of the self-propelled security road barrier according to the invention are evident, wherein the provision of a self-propelled cart with ground sliding means allows moving the security road barrier in a simple, rapid way.
As a matter of fact, because of the provision of the self-propelled cart, the security road barrier can be moved from an urban location to another urban location, according to the place where the potential dangerous situations are generated, and can be rapidly removed from the place where it is positioned in order to free the passage.
Because of the provision of the covering mask, the security road barrier can look like an ordinary urban decoration item, thus avoiding arousing alarms or concerns for the population. Moreover, the covering mask can be made with different shape or size. For instance, the covering mask can be a container suitable for being filled with soil and flowers in order to act as a flower box.
Because of the provision of vertical lifting means, the covering mask can be raised or lowered from and into the self-propelled cart, in such a way as to conceal the self-propelled cart.
For the sake of clarity, the description of the invention continues with reference to the attached drawings, which have a merely illustrative, not limiting value, wherein:
With reference to the Figures, a self-propelled security road barrier according to the invention is described, which is generally indicated with reference numeral (B).
Now with reference to
The self-propelled cart (10) comprises:
The sliding means (11) can be tracks or wheels, as shown in
Said self-propelled cart (1) can be moved manually by means of pushing.
Advantageously, the following parts are disposed inside the body (10):
The control means (M3) are connected to a receiver (Rx) mounted on the body. The receiver (Rx) is coupled with a remote control (T) in order to remotely control the control means (M3).
Two rear arms (12a) protrude laterally from the rear of the body. Two front arms (12b) protrude laterally from the front of the body. For example, the arms (12a, 12b) are metal sections with “H”-shaped cross-section, in such a way to have a good flexural strength and a good torsional strength.
The sliding means (11) are disposed between a rear arm (12a) and a front arm (12b).
The self-propelled cart (1) comprises lifting means (113) suitable for raising and lowering the frame (2).
Advantageously, the lifting means (113) comprise linear actuators (13) mounted on each arm (12a, 12b). Each linear actuator (13) is provided with a stem (13a) with vertical axis that moves vertically. The linear actuator (13) can be a hydraulic or pneumatic jack that is powered by a hydraulic or pneumatic system disposed inside the body.
The hydraulic or pneumatic system may comprise one or more pumps (P) that are hydraulically or pneumatically connected to the jacks. Each pump (P) is connected to a corresponding jack by means of a delivery pipe (14a) and a return pipe (14b) for a circulation of the working fluid.
Alternatively, the linear actuator (13) can be an electrical jack or a worm screw or an articulated parallelogram.
The frame (2) has a parallelepiped shape. The frame (2) comprises four uprights (20) that are connected by side-members (21a, 21b) and crossbars (22a, 22b). The frame (2) comprises two lower side-members (21a), two upper side-members (21b), two lower crossbars (22a) and two upper crossbars (22b). The uprights (20), the side-embers (21a, 21b) and the crossbars (22a, 22b) are, for instance, metal sections with “H”-shaped cross-section in such a way to have a good flexural strength and a good torsional strength.
The upper side-members (21b) are connected to the upper crossbars (22b) by means of internally protruding angle irons (23) in such a way as to reinforce the connection of the upper side-members (21b) to the upper crossbars (22b).
The linear actuators (13) actuate on the frame (2) in order to raise and lower it. The stems (13a) of the linear actuators are advantageously connected to the angle irons (23) as shown in
With reference also to
The covering mask (3) has two longitudinal walls (3a) and two transverse walls (3b) with outwardly tapered shape, going from an upper border (3c) to a lower border (3d).
The cross-section of the longitudinal walls (3a) is shaped as an overturned “U” in such a way to define spaces (32) suitable for receiving the upper side-members (21b) of the frame. Similarly, the cross-section of the transverse walls (3b) is shaped as an overturned “U” in such a way to define spaces (32) suitable for receiving the upper crossbars (22b) of the frame. In view of the above, the covering mask (3) is supported by the frame.
The covering mask (3) can be made in one piece with molded plastic material.
The lower border (3d) of the walls of the covering masks is disposed at a lower level than the bottom wall (31) of the recessed seat (30) of the container, in such a way that the bottom wall (31) is disposed above the body (10). The distance between the lower border (3d) of the covering mask and the bottom (31) of the recessed seat is higher than the height of the self-propelled cart (1).
Although the figures show a frame (2) that is separated from the covering mask (3), the covering mask (3) can be made of a sufficiently rigid material, such as metal or concrete, and the frame (2) can be omitted. In such a case, the covering mask is directly disposed on the self-propelled cart (1) and is directly raised by the lifting means (113).
Alternatively, the frame (2) can be integral to and made in one piece with the covering mask (3).
With reference to
The lifting means (113) comprise two linear actuators (13) that are supported on shelves (12c, 12d) of the self-propelled cart (1) and are provided with stems (13a) connected in lower position to the angle irons (23). Optionally, a board (13b) is fixed on each stem (13a) and is horizontally disposed under the angle iron (23), in such a way as to uniformly distribute the thrust exerted by the linear actuator (13) on the angle iron (23). Therefore, the horizontal board (13b) moves together with the stem (13a) of the linear actuator.
Two columns are disposed on each shelf (12b, 12c) of the self-propelled cart (1), acting as support for the horizontal board (13b) when the stem (13a) of the linear actuator is in a retracted position.
Optionally, ballasts (Z) suitable for increasing the weight of the security road barrier (B) are disposed on the self-propelled cart (1).
Optionally, the covering mask (3) can be obtained with a plurality of panels (37) disposed vertically and connected to the frame (2).
