ES2255374B1 - HYDRAULIC TRANSVERSAL BAND TO LIMIT VEHICLE SPEED BY THE PUBLIC ROAD. - Google Patents

Abstract

Hydraulic cross band to limit the speed of vehicles on public roads. It is constituted by a strip (1) that crosses the road and that is movable with respect to a "U" guide (2) embedded in the pavement, being able to adopt that two positions: one of retraction in which it fills with the pavement, and another emergency, which is achieved by the action of hydraulic cylinders (5) arranged inside the guide (2), at predetermined distances and anchored to the strip (1). The performance of the hydraulic cylinders (5) is commanded by sensors that detect the arrival of a vehicle at a speed greater than that indicated as a limit. If the speed is slower, the vehicle passes on the strip without altering its position of retraction.

Description

Hydraulic cross band to limit the speed of vehicles on public roads.

Object of the invention

The present invention, as expressed by the set forth in this specification, refers to a band Hydraulic transverse to limit vehicle speed by the public highway, which is marked with timely warning means of their presence or existence, for drivers  that approach the place and that they should slow down the speed of their vehicle for the imminent arrival in a limited speed zone, or for other legally established causes.

It is an object of the invention to achieve that said transverse band, or parallel bands distant from each other, they may be flush with the surface of the road so as not to constitute an obstacle to vehicles that pass freely through not exceed the indicated speed limit, or emerge partially from her to ultimately warn of the danger imminent to circulate at a faster speed than allowed. Area pop-up on which the wheels of the offending vehicle hit, can be regulated, during assembly, to suit the regulations of the place, being able to have only the function of bands audible sounds, or punishment bands for drivers reckless and can cause significant damage to the offending vehicle

Background of the invention

The bands are currently known Fixed cross-sections with a greater or lesser degree of roughness and emergency on the surface of the road, as well as in variable number and different distance from each other, depending on the committed to fulfill.

Also known are transverse bands that extend temporarily over the road and therefore are false or overlapping units, used for police control or of another nature.

On other occasions and for detention purposes that prevent the passage of vehicles, there are barriers at a certain height of the ground or linked to it both fixedly and provisionally.

Description of the invention

In general, the transverse band for limit the speed of vehicles for the public roads object of the invention is constituted by a rectangular section strip arranged transversely to the roadway and that is housed in a U-shaped guide previously fixed so that it is embedded in the pavement and perfectly in solidarity with him. The strip is vertically scrollable keeping parallel to itself to emerge to a greater or lesser extent from the surface, when assisted by several hydraulic cylinders arranged at distances convenient and that are anchored at the bottom of the guide in "U", also looking at the strip.

Hydraulic cylinders are part naturally from a hydraulic circuit where the timely intervenes pump driven by the corresponding electric motor, distributor, line pressure relief valves and delivery valves to the different cylinders, tank oil, etc.

The hydraulic cylinders are preferably of simple effect with spring retraction and its performance, or circuit activation, is carried out by means of sensors approach that detect the arrival of a vehicle, as well as its speed. When it exceeds a certain value, (for example 50 km / hour) the hydraulic cylinders extend so that the power strip emerges and the vehicle acknowledges the negligence of its driver, while if the speed is lower than that limit, the strip continues in its retracted position going practically unnoticed for the driver

The device is installed between two cuts made on the pavement, determining a kind of ditch where the "U" guide is perfectly embedded and secured. At the end corresponding to the shoulder, the ditch can pour into the sewer network or evacuate freely to the gutter, so that it dislodge water that may have come in through rain or other reason.

It is also expected that this water evacuation will be perform with a bilge pump, or pour it into a well waste.

To easily evacuate this water, the guide in "U" includes under its soul or branch of union of the branches, another "U" profile that has collector channel functions of the water, covering the opposite end to the one poured into the sewer or in an intermediate tank.

It is also planned that the strip includes superiorly anchoring means for a rod structure, to railing mode, with barrier functions.

To facilitate the understanding of characteristics of the invention and forming an integral part of this Descriptive report, accompanying some sheets of plans in whose figures, with an illustrative and non-limiting nature has been represented the next:

Brief description of the drawings

Figure 1. - It is a perspective view of a cross band to limit the speed of vehicles on the track public, according to the invention, being located in a small trench crosswise on the road.

Figure 2. - It is a cross section of the shown in figure 1.

Description of the preferred embodiment

Referring to the numbering adopted in the figures, we can see how the hydraulic cross band for limit the speed of vehicles on public roads, which the invention proposes, is susceptible to vertical displacement staying inside a small ditch that crosses the roadway, flush with the pavement in its inoperative position, or well, emerging with respect to him, to be noted the passage of cars that do not respect the limited speed in that area.

The entire device consists of a moving part (1) or transverse band itself, and another part fixed (2) in which the previous one is guided and that is perfectly Solidarity on the road.

In this exemplary embodiment, the guide (2) It has a "U" section with the ends of its angled branches outward to determine a pair of wings (3) endowed with countersunk holes (4) for perfect supportive anchorage to the firm, by means of appropriate screws.

The mobile part or strip (1) is a sheet folded in "U" and arranged in an inverted position, of angles preferably rounded and that rises or falls with certain clearance in the guide (2) by the existence of the cylinders hydraulic (5) anchored vertically to the bottom or core of the "U" (2) and that of the strip (1), through studs (6) welded and that they are carriers of a hole of passage of the screws of anchorage.

A sensor (not shown in the figures) detects that a vehicle is approaching a speed greater than the allowed, and command the extension of the hydraulic cylinders (5) so that the lifting of the strip (1) takes place and that interfere with the wheels of the offending vehicle.

The hydraulic circuit of which the cylinders, nor has it been represented as being an element in itself known.

To adjust the clearance between the guide and the strip, optimizing the sliding, there are some skates nylon or similar sliders, preferably anchored to the part Fixed cross band. In this example shown in the figures, the skates are referenced with the number (7) and materialized by a disk fixed with screws to the branches of the "U" guide (2) at two different heights.
