Description

Piezoelectric lighting device Zebra steps with optional vehicle passage counter.

Object of the invention

The object of the present invention relates to a device that allows the lighting of zebra crossings especially at night with a piezoelectric type mechanism that It can not only function as an actuator but also as a generator electric to illuminate an arrow in the zebra crossing that indicates the  direction and direction in which you want to cross the pedestrian. Also as Device option can be incorporated in the middle of the zebra crossing bands tiles that transmit a signal electric to count the number of vehicles that circulate from so that the competent public administrations elaborate the statistics deemed appropriate.

Background of the invention

As I checked in the database put at the service of the public by the SPTO, there are several mechanisms that they pursue the same objective as the one sought with this device, which is none other than improving the conditions of road safety for cars and especially for pedestrians. Without However, they have disadvantages with respect to what is presented. In such sense, there are devices that use for operation of the electricity grid or photovoltaic panels or posts that support information panels that indicate that a pedestrian You want to cross. However, all these mechanisms present inconvenience

\ circ

First, they must be activated by the pedestrian. Which means that if a pedestrian, for example a child, Forgets to press the device's push button and cross the zebra crossing, the mechanism does not work. This problem is solve with my invention since in normal conditions all pedestrians  must step on the piezo tile that precedes the passage of zebra.

\ circ

Second, similar mechanisms supposes architectural barriers in the urban environment and especially in sidewalks that are already saturated incipiently by others devices such as those related to paid parking in areas of restricted parking. All these systems require a post that serves to hold the photovoltaic panels or that serve as a support for information panels. The system that presents blends and camouflages perfectly with the urban environment at Do not present any outgoing.

\ circ

Third, none of the systems similar presents an arrow indicating the direction and direction in the one that will cross the pedestrian, although the driver can deduct it because the area that corresponds to your address lights up March

\ circ

Fourth, none of the systems Similar presents the option of being able to be used as an accountant vehicular.

Description of the invention

It is a lighting device with lamps, preferably type Ieds protected within a housing to the effect, to put in pedestrian zebra crossings, specifically within the fringes or outside, on the periphery of said bands defining the preferred crosswalks or crossings of zebra painted on the asphalt on the public road or road.

This mechanism is singled out by presenting two arrow-shaped lighting bands, preferably based of LEDs, one on each side of the zebra crossing or inside it, and that indicate with a flash or light burst (burst with a cadence similar to the one used on the runways of airports) the direction in which you want to cross the pedestrian, indicating to the drivers of the vehicles, of the existence of a step of zebra and its imminent use by a pedestrian.

The power supply and / or activation of these luminous elements is constituted by tiles composed, for example, of a piezoelectric polymer. Throughout case, it will be a material that resists continued use and strong thermal contrasts

These piezo tiles with the tread of the pedestrian, or several, generate the electricity needed to illuminate Zebra crossing autonomously, even if you don't want the pedestrian, this generation being optionally complemented piezoelectric power, by other tiles in the middle of the passage of zebra.

If you choose a simple variant, the piezo tiles placed on the inclined ramp that communicates the sidewalk with the zebra crossing, they will have a double function, they will be device actuators and power generators Electrical for the device.

If you opt for the most complete variant, the tiles placed in the inclined plane of the access of the passage of zebra would function preferably or exclusively as actuators by essentially placing the power supply of the device in the tiles placed in the zebra crossing.

And finally if you opt for a device complete and with vehicle step counter, the tiles piezoelectric located in the middle of zebra crossing, in addition to generate electrical current will transmit an electrical impulse even counter that will indicate the number of vehicles that have crossed. Vehicle step counter that will allow entities Public statistics.

Of course all the remaining electricity can be returned to the public power grid of the community or conducted to an accumulator or battery that serves to complement or guarantee the entire system in case of failures or ups and downs in the device.

Description of an embodiment

In view of the described figure 1 they can observe the bands of the zebra crossing (4) with the device that it is constituted in its basic version by two lighting arrows (1) composed of a cord with preferably led type lamps (due to its low maintenance, high duration and low consumption) protected inside a tubular housing of section in the form of "U" and composed of an unalterable material, for example, 316 stainless steel or aluminum. Going the whole set embedded in the pedestrian and one-piece zebra crossings to favor its withdrawal when asphalting or repairing any element of the zone.

These arrows, each indicating a direction contrary to the other, they are fed and / or activated by the Piezoelectric tiles (3) perfectly embedded and without protrusions on the inclined plane of the sidewalk, and which will be composed of, by example, a polymer such as vinylidene polyfluoride, PVDF, semicrystalline, or polyimides with piezoelectric properties. In any case it will be a material as unalterable as possible, which support a continuous and variable pressure and great contrasts thermal, and moisture, and having the piezoelectric properties They chase each other.

There will be a small casket (2) where the connection between the tiles and the lighting arrows, and where there will be a small electronic circuit for control and protection of system so that the electrical imposition sent to the LEDs, is a type burst. This system is in duplicate on each side of the step of zebra, since each side only activates an arrow.

In view of the described figure 2 you can be observed as the device that is constituted in its version complete, consists of the same elements as in the basic version but it has also been added a battery or accumulator (6) and a band consisting of special piezo tiles (5) that support vehicle traffic, even heavy, and a receiver of the signals of the passage of vehicles (7) that send them tiles, to proceed to their counting or scrutiny.
