Abstract

The invention relates to a system for reducing vehicle speed that consists of placing one or more protruding elements, bumps or protuberances at the sides and/or in the central part of the pavement of a road, which are used as separators and/or allow traffic to travel over same, while taking advantage of sidewalks as additional protruding elements; wherein all of said elements serve to indicate the route to be followed and force the vehicle to travel at low speed, avoiding abrupt changes when passing over the elements. The protruding elements can be placed at a slant or transversally with respect to the longitudinal axis of the street. Those placed at the sides are longitudinally offset and they are placed alternately along the road. They can also be placed at the same level as the street, thus operating by narrowing the same. In this case, one or two side bumps that can be complemented with central transversal humps are used.

Description

SPEED REDUCING SYSTEM FOR VEHICLES

FIELD OF THE INVENTION.- In the sections of the roads where it is desired to reduce the speed of the vehicles to improve road safety, along with pedestrian crossings, schools, curves, roundabouts, dangerous points, etc.

STATE OF THE TECHNIQUE.- Currently, in the places that you want to reduce the speed of the vehicles, miniglorietas, setbacks, pillows, mattresses, plateaus, hammers, separating islets, point narrowings, modifications of intersections in T, and zigzags are placed , all of which are expensive. Roundabouts are also effective in forcing speed reduction, but very expensive. The use of artificial loins or brothels is mostly used, although they are less expensive due to the large number of them that are needed, are dissuasive and are usually placed in places with greater number of accidents or victims, schools, residential, etc. When the visual or related warning signs are not respected or observed, vertebral injuries, noise and collision can occur in cars and collisions when found unexpectedly and having to make a great speed reduction. With the present invention it is possible to eliminate or reduce the aforementioned drawbacks.

OBJECTIVE OF THE INVENTION

Use small protruding elements, projections or loins which are placed alternately or not on both sides of the road and / or in the center of it, and which can create a narrowing in the road, and recommend, oblige or warn the driver where to make a zigzag, a curve or a slope without having to make the annoying jump. The system can use sidewalks as lateral protruding elements.

Optionally add a new system of alert cross bands.

Using a simple, economical, versatile system, easy and quick assembly and disassembly, which gives security, reduces the risk of collisions and prevents damage to vehicles. Not having competition the advantages mentioned with all current systems.

Being able to place this system in a greater number of places as its cost is lower and cause less inconvenience to drivers and the inhabitants of the area.

Add on the lateral or central projections on which there is no circulation, flexible vertical elements consisting of fins, pennants, bollards, plants or shrubs or small hedges covered with reflective paints, which improve the frontal visualization. DESCRIPTION OF THE INVENTION.- The first certificate of addition to the patent No. P201100200 by speed reduction system for vehicles of the invention of the type that uses protruding elements or projections, speed reducers on the road (RDV), consists of placing in the sides and / or in the central area of the pavement of the road one or more protruding elements, projections or projections, which are used as separators and / or circulated on them, taking advantage of the sidewalks as additional protruding elements, and showing all of them the itinerary to follow and forcing the vehicle to drive at low speed and avoid sudden oscillations when passing over them. The protruding elements can be placed inclined or transverse with respect to the longitudinal axis of the track. The ones placed on the sides are offset longitudinally from each other and alternate along the road. They can also be placed at the same height as the road, then acting by narrowing it. In this case, one or two lateral projections are used, which can be complemented with intermediate transverse loins.

The protruding elements can be straight, curved, in the form of triangular prisms with rounded corners and edges, half of spherical or ovoidal caps, of continuous section, such as loins, or formed by one or more rows of spherical caps, section caps trapezoidal or small loins of circular segment section. Both the protruding elements of a section and those formed by two or more rows, can take the form of a ravine or a very elongated sinusoid, of little amplitude or formed by two very open arches.

The protruding elements, prefabricated or not, can be placed glued, threaded by screws, embedded or embedded in pressure by means of studs or partially embedded in a recess, rectangular parallelepiped channel or in cylindrical vertical holes made in the pavement of the roadway and the screws or corresponding metal hooks. Concrete may be added for fixing. Spherical caps and small loins with screws or studs are embedded as large pushpins. Vertical cylindrical holes are made with drills. A variant builds the outstanding elements in situ.

The inclined central protruding elements on which it can be circulated, releasing them between the wheels, carry arrows on its body showing the direction of advance. The arrow can also be placed painted or glued on the ground at the front end of the loins or rows of protruding elements. Caps shaped elements can be placed on at least one side of the road or spherical semi-packages which act as lateral stops.

The transverse central elements can be formed by at least one spine or row of caps or pushpins, and can be conveniently placed spaced in the center or alternated and each displaced to one side of the road. An arrow between the loins or rows shows the direction and area through which it is necessary to circulate. You can add a spherical cap lengthwise on the side.

In the previous or alert zone and optionally, one or more rows formed by a series of protruding elements of lower height, spherical or ovoidal caps, which warn of the low speed zone and are placed as transverse warning bands (BTA). of the presence of greater obstacles and they are placed glued, embedded or embedded in pressure by means of screws or studs or threaded like large pushpins.

The protruding elements used can be colored with reflective paints of one or more bands of alternating colors, and can be used coded as follows or similar:

a) When allowed but not to be circulated on them, yellow or orange stripes alternated with white or black ones will be used.

b) To advise to circulate above and along the loins and to follow its route, green stripes alternated with white or black ones will be used.

c) When they cannot be passed or circulated on them, red stripes alternated with white or black ones will be used.

d) When it is obligatory to circulate or roll over them, white stripes alternated with other black ones will be used.

On the lateral or central projections on which it is not circulated, flexible vertical elements consisting of fins, pennants, bollards, plants, shrubs or artificial pots covered with paints or reflective material, which improve the frontal visualization, can be placed. The fins and pennants can carry several colored stripes or a narrowing signal. A mixture of the aforementioned elements can be placed. The flexible vertical elements can be easily assembled and disassembled, introducing pressure sausages.

The system of the invention will be placed mainly on one or two-way roads and that do not have excessive traffic.

The use is maximum when the route is made between a sidewalk, which acts as a protruding element or lateral stop, and an protruding element or protrusion placed on the other sidewalk or opposite side of the track, both acting as stops and therefore deterrent from running at high speed due to the need to make the curved path .

The protruding elements will have a height between 7 and 10 cm. approximately or what is allowed by current regulations and related to the desired speed limit in the area. The chord of the segments of the loins can have between 20 and 60 cm., The one of the spherical segments between 10 and 50 cm., And the loins between 50 and 300 cm. approximately. The longitudinal separation between loins can be between 4 and 10 m. depending on the size of vehicles that circulate in the area. The dimensions are subject to the type of vehicles, the required speed of the same and the regulations. Taking into account that its operation is different from the current one, it should be assigned different rules. As a route is facilitated without having to roll over the protruding elements, said elements may have a greater height, which although it is allowed to roll on them, oppose a greater difficulty or inconvenience when passing over them. The profile or edges of the ends of the loins should have a very sharp angle of approximately 10 ° to 25 °. The spherical caps or pushpins of the rows can have different heights, placing them in decrease towards the end (s).

The material used for the protruding reducing elements can be:

Plastic, resins, rubber or rubber, asphalt, concrete, steel or concrete with a rubber or rubber cover, especially hard rubber and rubber, that do not deteriorate with moisture, are resistant and durable. Materials can be used in the external areas with the colors of the signs themselves, so that when they lose the reflective paint, the color used in the signals used remains: yellow, orange, white, red, black, etc. If tomillería is used it will be resistant and made of stainless steel or metals. For the outstanding elements can be recycled and take advantage of the tires of the vehicles and the plastics, with the consequent saving and great benefit for the environment.

When approaching the vehicle to the restricted area, it is in addition to the visual warnings of speed limitation, the current warning bands or the one formed by the heads of the nails or pushpins, which cause oscillations to the vehicle. The driver will try to avoid the outstanding elements at low speed, making a detour, zigzag or undulation. Motorcycles and bicycles can travel at reduced speed through the zigzags or through the narrowings made between the protruding elements and / or the road.
