Description

DESCRIPTION

Passive safety device for cyclists.

Object of the invention

The present invention relates to a device for protecting the physical integrity of cyclists in the event of a collision with the rest of the vehicles with which they share the same tracks.

Background of the invention

The use of bicycles has continuously experienced in recent years a continuous boom. The search for a healthier lifestyle, as well as its outdoor practice make cycling "amateur" one of the activities with the largest number of practitioners in the world. This is evidenced by manufacturers, whose sales results grow from Continuous way every year.

This continuous increase in the number of amateur cyclists has a problematic part of which the authorities have long been alerting. The fact that cyclists share their hobby with the rest of motor vehicles has meant a constant increase in road accidents. In the event of a collision, it is always the cyclist, due to the lack of protections of a bicycle, which is worse off.

It is worth mentioning the case of urban cyclists who, for ecological or practical reasons, choose the bicycle as a usual transport system and the professionals: couriers and product distributors, whose number has increased since the entry into the market of online companies and who cohabit in a much more narrow and frequent way with motor vehicles within cities, they are also susceptible to being abused. In addition to the continuous awareness campaigns carried out by the different governments. It is necessary to provide cyclists with the greatest possible protection in the case of being run over by other vehicles and this is the purpose of the present invention.

Description of the invention

The present invention relates to a passive safety device, intended to protect the cyclist, once the collision has occurred. It consists of the following parts:

- Central body: Anchored to the upper tube of the bicycle, it can be easily removed using a thread system. It houses the removable and rechargeable battery that feeds the system, the control unit, which is what determines, depending on the parameters that have been previously programmed, if the impact is strong enough to deploy the system, so such as the system on and off button, the battery charge level indicator, a turn button that allows the entire assembly to be tilted to facilitate the assembly and disassembly of the bicycle once the activity is finished and the power and turning off the presence and right / left turn lights.

- Connectors: This is a piece that, starting from the central body in two directions, connects it with the rest of the system. Its objective is twofold: on the one hand, the electrical connections that transmit the information between the central unit and the rest of the assembly run on the inside and on the other they help to place the lateral units in the right place and height so that they are the first that receive the impact of the vehicle and also do not hinder the cycling of the cyclist in any of the positions that it can perform.

- Side units. They form the final part of the system, they are made up of Impact Bars, which are directly hit by another vehicle. These bars are located away from the side Units at a minimum of 7.5 cm. based on the following formula:

Maximum speed allowed on conventional roads for motor vehicles = 90 km / h

90 km / = 25 m / sec, Inflation time of the bags according to the manufacturers themselves 0.003 seconds.

E. Space = V. Speed / T. time

E = vxt 25x0.003 = 0.075 mts = 7.5 cms.

This margin of distance allows the inflation of the bags before the collision between the vehicle and the cyclist. Its mission is to transmit the force of the impact by means of the sensors that carry inside, these sensors, detect and send the information to the central unit of the activating device.

The Impact Bars leave the Side Units inside which the Inflation Devices are housed, inside is the solid fuel mixture, which if necessary, after receiving the order of the central unit, generates a spark proceeding to the combustion of the mixture, generating the gas and inflating the bags.

- Bags: high-speed inflation allows the creation of a protective barrier between the rider's body and the vehicle, mitigating the damage it may suffer. These bags are in compartments that are opened by hinges allowing their exit. Since the deflation of said bags is done through holes made in them, controlling the density of said holes and their size provides a longer deflation time, thus allowing the rider's body to be protected for the appropriate time. .

Finally, these Side Units incorporate a lighting system consisting of presence lights internally housed in the units and external directional ones that indicate the direction of rotation, right / left. These lights are controlled from the central body.

The sequence of operation would be as follows: The blow is received on the impact bars, these transmit the blow to the collision sensors that in turn transfer the information to the control unit; Depending on the parameters that have been programmed, this unit puts into operation the inflation devices that, after combustion of the solid mixture, inflate the bags generating a barrier between the colliding vehicle and the rider's body.

At this point, it should be noted that the system will be switched so that, regardless of which of the two impact bars is hit, right or left, inflation of the two bags will occur simultaneously.

Preferred embodiment

To better explain the invention, an embodiment is described below, with the aid of the figures, which, however, does not exhaust the possibilities and characteristics of the invention.

The device has a central body (1) of dimensions that do not hinder the free exercise of pedaling of the cyclist, even in less common positions such as the rise of slopes, where an advanced posture is adopted even rising from the saddle.

Its anchor point (2) is very close to the steering tube of the bicycle: it is located on the central axis of the bicycle in the so-called upper tube (7). Being the rest of the symmetric components. It is proposed that its lower base has a half-round shape for better settlement on the bicycle tube that is cylindrical. Outside there are a series of controls (11) for the management of the lights and also the button (12) on and off the whole assembly. It has a fast threaded anchor system (9).

From its front part the connectors (3) arise, which are actually a single piece that crosses this central body and by means of a gear located inside the central body, you can lower the whole assembly, making it easier for the cyclist at the beginning and at the end of the activity get on and off the bike. In the central body is the button (10) for folding the device, this button allows the rotation of the connectors and side units (4) making it easier for the cyclist to assemble and disassemble the bicycle.

Through the internal structure of these connectors run all the connections and the wiring that transfers the information between the different components. These connectors also, by their form, have the mission of moving the Side Units (4) away from the Central Body, allowing a necessary space for the rider's body to be protected when the bags are deployed. They also help to place the Impact Bars (5) at the appropriate height so that any possible blow takes place first in them.

At the end of the Connectors are the Side Units (4) of sufficient dimensions to accommodate the inflation system (14), the folded bag (15) and the lighting system (13). From its front part, the Impact Bars (5) arise, these are the ones that first receive the impact and have internal sensors (6), which, based on the information that has been programmed, starts the operation of The whole set. Part of this bar will have a gap that allows the sensors (6) to be connected to the central body (1) through the Connectors (3).

In the Side Units there is also the lighting system, consisting of presence and direction lights (13) that indicate the direction of rotation. Said lights are controlled from the control unit (8) located in the central body (1).

The whole set must be configured in such a way that, for effective protection of the cyclist, the two bags are always inflated simultaneously, regardless of the side that receives the collision.

Both morphology and construction materials admit varied designs provided they provide adequate insulation of elements such as moisture and splashes. Being able to add rubber liners in the areas most susceptible to scratches.
