    DESCRIPTION
    SELF-INSTALLING ROBOTIZED SNAKES FOR SNOW
    TECHNICAL OBJECT OF THE INVENTION
    The invention presented refers to a non-slip device of those placed on the wheels of cars to ensure driving conditions when the road has snow or ice.
    The device represents a substantial improvement over similar ones since it is of a robotic type that allows the coupling of the non-slip on the wheels without having to get off the vehicle. The main conditioner is specified in its previous installation on the tractor wheels when its possible need is anticipated. The device remains in the waiting position until the conditions of the road or the traffic authorities advise or, where appropriate, force the placement in the working position.
    SECTOR OF THE TECHNIQUE TO WHICH THE INVENTION REFERS
    The present invention has its effects within the scope of the Section of Various Industrial Techniques in the Transport chapter in relation to Automobiles, having an industrial impact on the manufacture of accessories related to the circulation of motor vehicles on roads public with snow or ice.
    BACKGROUND OF THE INVENTION
    The current state of the art indicates that there is a large number of non-slip devices for use on public roads in case they are covered by snow or ice.
    Basically, four main types are known as more common:
    - Those that are incorporated into the tire itself
    - The chain type
    - The band type
    - Spider-like ones
    The former describe special tires equipped with nails or studs that should
    5
    10
    fifteen

    30
    be mounted at the beginning of the winter season or carried in the trunk for assembly in case of unforeseen weather. You can also include in this group the spray solution that is applied at the same time you need it and has a sufficient duration to get out of hurried situations.
    Those of the second type based on chains, are the most traditional. They should be carried in the trunk, as a precaution, throughout the winter season. They are very effective although their main drawback is that, since they have very destructive effects on the road, they must be placed only when the snow-covered sections begin and removed when the road begins to be clean. Skill is required to place them properly with the aggravating factor that the need arises normally in very adverse weather conditions. Anyone is not able to mount them and if done wrong, blows occur on the body and other parts of the vehicle.
    The solutions of the third group, band type, are light, have a limited duration, should be carried in the trunk to place them at the time they are needed and are easier to put.
    Those of the fourth group of spider type, should also be carried in the trunk to put them when necessary. Its placement is quick and simple although they are bulky and heavy.
    It is worth mentioning a fifth group, which is the most related to the invention presented in this document, concerning the devices that are coupled or put into operation without leaving the vehicle with the undoubted advantages that this entails.
    In that group, which we can call automatic type, the inventor knows the following records:
    - EN 1070265 U “Tire with built-in chain device”
    -EN 1073475 U “Improved non-slip device incorporated in the rim”
    -EN 1074824 U “Device permanently incorporated in the car for automatic mounting of non-slip accessories”
    The first two, similar to those of the spider type, describe solutions based on
    5
    10
    fifteen
    twenty
    25
    30
    telescopic arms that are mounted on special tires, permanently installed. When not needed, the arms are hidden with hubcaps. When the cold season approaches, the driver must remove the hubcaps and circulate without them until the need arises to travel on snowy or icy roads at which time, with the vehicle stopped, act on the existing button on the dashboard and wait for the coupling of the arms on both wheels, is finished. If any of the arms cannot be coupled by coinciding with the wheel support, it is sufficient to move the vehicle slightly.
    The third, similar to the band type, is a band that is placed on the wheel automatically. In this case, the solution is even more complete than that of the usual textile bands because they can also incorporate small stretches of chain or any other non-slip element.
    It is also a fixed installation, valid for any wheel size, which is permanently incorporated into the vehicle. Once the positioning button has been pressed, it advances slowly until the two wheels are completely covered with the band at which time a warning is received and the march can continue.
    Although these records exist, the inventor has no news that these inventions have been developed and marketed so he conceives this new device that is to be developed with the support of the most advanced robotization and remote control techniques.
    Finally, we must mention in this fifth group, automatic type, a chain type solution that has been commercialized and works relatively well with certain drawbacks.
    It is permanently installed in the vehicle, as a fixed installation, which is mounted in the vicinity of the rear wheels of trucks or coaches. It is formed by a pair of casters with a series of radial chains fixed to the casters by one end, the other end being free. When its use is required, there is a mechanism that approximates the wheels inside each rear tire with which the wheels begin to turn and the chains adopt a radial position operating as whips and passing under the wheels

    that are treading them with the consequent increase in adhesion.
    Taking this background into account, the inventor has focused especially on the idea of the three automatic records that have been cited above, that is, on the automatic ones assimilated to the spider type.
    DESCRIPTION OF THE INVENTION
    The present invention, as advanced in previous paragraphs, refers to a snow-slip device of automatic installation within the spider type.
    It is a new concept of snow chains with which it is intended to change the way of calculating and designing the itineraries of autonomous cars of the near future as well as in current cars, gaining in comfort and safety.
    It is an accessory that coupled to the vehicle's tractor wheels, has a centerpiece with five articulated and robotic arms that remain folded, during normal driving, unfolding, at the driver's discretion, when the road conditions require it, offering a considerable increase in the adhesion between the wheels and the track by action of its most extreme parts.
    Regarding the number of arms, the five has been chosen because, in that way, they are distributed at 72 degrees sexagesimal between axles which means a free arc on the wheel of about 50 degrees that is enough to easily place the wheel in a position that allows the entrance of the five non-slip plates at the same time. The central plate or core is the base that joins on the wheel or on some provisional accessory that is installed on it in the winter period. In turn, said plate supports the five articulated arms and associated mechanisms.
    Each arm has a pivoting section on the core, a second intermediate telescopic section and a third pivoting section on the former which constitutes the staple or non-slip plate that fits on the tire in its working position.
    The actuators, which generate the necessary movements, are located in the arms and in the central plate, all of which are remote controlled from the dashboard.

    or, in the case of very advanced autonomous vehicles, from the central computer of the vehicle that will generate the appropriate orders as soon as it detects the need for chains.
    In principle, the remote control installation is done independently with a button for each wheel, since it is normal that they are never in coincident positions and when one wheel is in a suitable position to receive the clips, the other may not be.
    It is not ruled out, however, a sequential coupling of the arms as the vehicle advances at a small speed and in that case you can think of the simultaneous coupling on both wheels and even increase the number of arms up to six or seven.
    The following paragraphs include drawings that allow us to understand the details and operation of the invention as well as a complete description of the preferred embodiment by its inventor who, as usual, reserves the right to introduce small modifications that do not alter the basic aspects that They preside over their invention.

    DESCRIPTION OF A PREFERRED EMBODIMENT
    Self-installing robotic snow skid (Figs. 1 to 8) which, coupled on the tractor wheels of a car, can be deployed at the driver's discretion or, on scheduled orders, to allow safer circulation on snowy or icy roads. In an embodiment preferred by its inventor, they are non-slip known as the spider type

    designed for permanent installation in driverless cars and also for temporary or permanent installation in conventional cars.
    In (Figs. 2) you can see its installation on a wheel with rim (1) and tire (2) showing in (Fig. 1) the frontal view in the rest position and in (Fig. 2) the profile view corresponding also to the rest position.
    In (Figs. 3 and 4) the same installation can be observed with the front and profile views corresponding to the working position.
    The device is basically composed of a main plate (4), flat or slightly bulged that is fastened by means of thymes (6) to a primary support (3) integral with the wheel hub. The arrangement of the thymes (6) and the torn holes (5), made on the main plate (4), allows the rapid placement or removal of said main plate (4), with all its components, which is very useful to place it in the winter periods and remove it when there is no expectation of snow or ice. This operation is not necessary in autonomous vehicles because in them the installation is permanent being perfectly integrated from the moment the vehicle was manufactured.
    In order to protect the mobile elements of the invention, located in a perimeter zone, very exposed to possible damage by rubbing or bumps on the curbs of the sidewalks or any other projection of the traffic lanes, a discontinuous protective ring is provided (4.1 ) of the same material as the main plate (4) or of a hard neoprene, represented schematically in all the figures.
    The anti-skid of the invention are distributed on the main plate (4) forming regular polygons that, preferably, are chosen from five, six or a maximum of seven sides.
    The inventor considers the number of five non-skid modules per wheel to be very adequate, which implies a theoretical spacing of 72 degrees which, in practice, taking into account the width of each of them, leaves free tire sections of about 50 degrees, sufficient so that the non-slip clips can be attached to the tire (2) without moving the vehicle. The figures that
    5
    10

    included in this document refer to the case of regular pentagonal distribution. In (Figs. 1 to 4) it can be seen that each of the modules consists of an arm (9), a clip (7) and a bracket (10), all of these parts being incorporated in the main plate (4). ).
    Each arm (9) is formed, in turn, by a staple support (9.1), a rotating support (9.2) and an extension actuator (9.3) located between the two previous ones.
    The clip (7) is the one that does, by itself, the functions of non-slip with the help of some skewers (8) that are a kind of protuberances that penetrate, on the one hand, in the neoprene of the tire (2) and in Snow or ice on the opposite side. It is rotatable on the x-x axis which relates the staple itself (7) with the staple holder (9.1) which, in addition, acts as a stop in the unfolded staple position. The movement from its resting position to its working position and vice versa is carried out by means of the staple actuator (12).
    The arm (9) can rotate on the y-y axis, which relates the rotating support (9.2) to the main plate (4). The rotation of the arm (9) causes the movement of all its components and that of the clip (7) being executed by the thrust made by the folding actuator (11) which, on one of its ends, rests on the bracket (10 ), integral with the main plate (4) and at the other end, rests on the fixed part of the extension actuator (9.3). This extension actuator (9.3) serves to move the swivel support (9.2) and the staple support (9.1) away from each other, that is, it is used to modify the length of the arm (9) which is necessary for the coupling of the clip (9.1) on the tire (2) in the working position, to retract the arm to its resting position and also for adapting the device to different wheel diameters.
    In summary, it can be said that the movements of some components with respect to others are carried out by means of the three actuators mentioned which are the folding actuator (11), the extension actuator (9.3) and the staple actuator (12).
    These actuators are preferably electromechanical, although other types such as tires or hydraulics are not ruled out.
    Its movement is executed by means of micromotors that are incorporated in the different pieces and are remotely controlled by radiotelecinesia procedures. That is, the invention applies classical robotics solutions.

    taking into account that all movements are performed in a vacuum demanding a minimum power. Each actuator with its micromotor incorporates a receiver that receives the orders issued from the transmitter, located inside the vehicle, with controls available to the driver or related to the on-board computer. Once the main components of the device of the invention have been described, its operation can be easily understood with the aid of the aforementioned (Figs. 1 to 4) and of (Figs. 5 to 8).
    (Fig. 2) shows, as indicated above, the resting position. In the deployment process the first step is the one indicated in (Fig. 5) where it is observed that the arm (9) and the clip (7) have turned a certain angle pushed by the folding actuator (11) that is supported by the bracket (10) and in the fixed part of the extension actuator (9.3).
    The second step is represented in (Fig. 6) where the deployment of the clip (7) takes place due to the effect of the clip actuator (12) with one end in the clip holder (9.1) and the other in the clip itself (7) the movement being limited by abutting the staple heel (7) with the staple holder (9.1), which is in its final position with respect to the arm (9).
    The third step is represented in (Fig. 7) in which we see that there is an elongation of the arm (9) by means of the extension actuator (9.3) supported on one side on the rotating support (9.2) and on the other in the staple holder (9.1).
    The fourth step is the one shown in (Fig, 8) where the arm (9) is coupled on the main plate (4), the clip (7) being very close to the tire (2). In this movement, the folding actuator (11) intervenes again.
    In a fifth step, the extension actuator (9.3) intervenes, which shortens the length of the arm (9), until the clip (7) is well attached to the tire (2) with its spikes (8) pressing on it as It is represented in the work position corresponding to (Fig. 4).
    This process is performed in a fully automated way as a result of an order given from inside the vehicle when it is stopped. It can be simultaneous or sequential. In the first case all the arms (9) move at the same time for which there must be a position control that authorizes the movement when none of the arms coincide with the wheel support on the
    5
    10

    ground. In this case, the inventor foresees a first action of the coupling on a tractor wheel and then on the other in a second phase.
    In the event of sequential coupling, the program is prepared so that the arms are coupled successively at the moment when there is no impediment either by the vehicle body or by the ground. In this case, we even think about deploying at a small speed. All the movements described in the aforementioned steps are performed in a vacuum, which implies the great advantage that the power of the micromotors is very small, since only slight friction between parts and others must be overcome.
    It is taken into account, however, that the non-slip in its working position has very important solicitations that could cause deformation of the arms or their dislocation. This detail is satisfactorily resolved thanks to the special design of the main plate (4) which, upon receiving the staple holder (9.1) tightly, acts as an immobilizer stop of said staple holder and consequently of the staple itself (7) whose detail It can be seen in (Figs. 1 and 3). It is understood that the bolt that joins both parts must be sized to withstand the strong stresses of the tractor wheels.
    The remote control device is not described as these are highly developed solutions currently with very small electronic components that must resolve the wireless communication between a transmitter and several receivers very close.
    It is not considered necessary to make the content of this description more extensive so that a person skilled in the art can understand the scope and advantages derived from the invention, as well as develop and implement the object thereof. However, it should be understood that the invention has been described according to a preferred embodiment thereof, so it may be subject to modifications without implying any alteration of the basis of said invention; that is to say, the terms in which this preferred description of the invention has been exposed should always be taken in a broad and non-limiting manner.
