DEVICE WITH ELECTRICAL OR PNEUMATIC ACTUATION OF A FOLDING MECHANISM FOR ENCOURAGEMENT OF REDUCTION OF VEHICLE SPEED
The device with electrical or pneumatic actuation of a folding mechanism for encouragement of reduction of vehicle speed consists of bars with accelerometers that function as step-on sensors, which transmit information to a controller that immediately determines the speed of the movement of a vehicle, after which it sends an order to an actuator with electric motor or a pneumatic actuator with an aim of raising the folding speed reduction mechanism in the case when the vehicle moves at a speed that is higher than the one programmed into the controller and after a certain period of time to return the device to its standby position, or to leave it in the standby position, i.e. not to raise the folding speed reduction mechanism. if the vehicle is moving at a speed that is lower than the one programmed in the controller.
The invention “Device with electrical or pneumatic actuation of a folding mechanism for encouragement of reduction of vehicle speed” refers to the class “Construction”, in the field of “Devices that are built in the roadway” and in the section “Embedding sensors on the roadway or other road surfaces”. According to the International Patent Classification (IPC). the invention belongs to the class E01F11/00. Also. the invention refers to the subsection “Devices for preventing or limiting traffic”, corresponding to the class E01F13/00.
TECHNICAL PROBLEM SOLVED BY THE INVENTIONThis invention refers to the performance of a so-called “intelligent speed bump”, where the speed of the vehicle is determined by the step-on sensors, after which the actuator of the folding mechanism for slowing the vehicles is activated, by raising the lower folding bar that, at the same time raises the upper folding bar, forming an angular placement that provides maximum toughness and robustness when being hit by the wheels from the passing vehicles moving at a speed that is higher than the one programmed into the controller. After a certain period of time, the device returns back to its original, standby position.
STATE OF THE ARTIn general, the so-called “speed bumps” are often built on the roadway itself or are placed at the top of the road, to regulate the speed of the vehicles passing over them. These devices are generally low enough to allow the vehicle to cross over them safely, but also high enough to force the vehicle to slow down as it goes over it, because otherwise they would cause a significant inconvenience to the vehicle. The speed bumps differ in length, but usually during their construction and implementation it is typical to leave space (curbs and grooves) between the impact part and one end of the closed road to allow for drainage. In many cases, spaces on both sides of the speed bump allow for passing of priority vehicles, although the effectiveness will depend on the type of the vehicle and the design of the road. Dynamic speed bumps differ from the conventional ones by being activated only when the vehicle is moving over a certain speed. Vehicles moving below the given speed will not experience discomfort when crossing over the “speed bump”. The dynamic speed bumps also may allow the passage of emergency vehicles at higher speeds. For example, the Actibump system, used in Sweden, is based on electrically powered equipment integrated into the road surface, that functions as a platform that drops a few centimeters when approached by a fast vehicle. Any vehicle approaching at or below the speed limit will pass at the level of the road. In this case, the system measures the speed of vehicles using a radar rather than through step-on sensors, which is a significant difference from the technical solution of the existing invention. U.S. patent application Ser. No. 13/102,868 reveal the road obstacle device that is fixed on the street and serves to control the speed of the vehicles, but it does not possess a speed detector, and has a folding mechanism for obstruction to the vehicles quite different from the one of present invention.
