Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

La présente invention a pour objet un dispositif de signalisation du retournement d'un engin agricole du type tracteur enjambeur. The present invention relates to a device for signaling the overturning of an agricultural machine of the straddle tractor type.

Il arrive encore fréquemment que des engins agricoles basculent sur le côté, et même se retournent, lors de l'exécution de travaux. It is still common for agricultural machinery to tip sideways, and even turn over, when carrying out work.

Ce genre d'accidents est plus fréquent avec les tracteurs enjambeurs utilisés dans le domaine viticole, du fait d'une part de la hauteur du centre de gravité de ces engins, et d'autre part de la forte déclivité du terrain dans certains vignobles. This type of accident is more frequent with straddle tractors used in the wine sector, due on the one hand to the height of the center of gravity of these machines, and on the other hand to the steep slope of the terrain in certain vineyards.

Ces accidents ont parfois de graves conséquences, en effet le conducteur qui travaille est généralement seul, et les champs ou vignes sont à l'écart des voies de circulation. Or il est possible que lors du retournement de l'engin, le conducteur demeure bloqué sous ce dernier sans possibilité de demander de l'aide.  These accidents sometimes have serious consequences, in fact the driver who works is generally alone, and the fields or vineyards are away from traffic lanes. However, it is possible that when the machine is turned over, the driver remains stuck under it without the possibility of asking for help.

On connaît des dispositifs de clinomètre permettant de mesurer l'inclinaison d'un objet, d'un véhicule par exemple. Ces dispositifs sont du type utilisant un ou plusieurs pendules, ou un élément liquide dont on peut détecter l'inclinaison de la surface. De tels dispositifs ne permettraient pas de détecter uniquement le retournement d'un engin agricole.  Clinometer devices are known for measuring the inclination of an object, of a vehicle for example. These devices are of the type using one or more pendulums, or a liquid element whose inclination of the surface can be detected. Such devices would not be able to detect only the overturning of an agricultural machine.

En effet, les engins agricoles sont de construction rigide, souvent dépourvus de moyens amortisseurs, en sorte que toutes les inégalités du terrain sont transmises, et que des dispositifs de clinomètre tels que ceux précédemment évoqués, se déclencheraient de manière intempestive.  Indeed, agricultural machines are of rigid construction, often lacking damping means, so that all the unevenness of the ground are transmitted, and that clinometer devices such as those previously mentioned, would be triggered inadvertently.

La présente invention a pour but de proposer un dispositif de signalisation du retournement d'un engin agricole du type tracteur enjambeur, permettant de remédier à ces divers inconvénients.  The object of the present invention is to propose a device for signaling the overturning of an agricultural machine of the straddle tractor type, making it possible to remedy these various drawbacks.

Le dispositif de signalisation du retournement d'un engin agricole du type tracteur enjambeur selon l'invention se caractérise essentiellement en ce qu'il comporte, sur ledit engin agricole, un moyen prévu apte à détecter un renversement dudit engin agricole et à déclencher un signal apte à commander la mise en oeuvre d'un moyen d'émission d'un signal de détresse.  The device for signaling the overturning of an agricultural implement of the straddle tractor type according to the invention is essentially characterized in that it comprises, on said agricultural implement, a means provided capable of detecting a reversal of said agricultural implement and of triggering a signal able to control the use of a means for transmitting a distress signal.

Selon une caractéristique additionnelle du dispositif selon l'invention, le moyen prévu apte à détecter un renversement comporte According to an additional characteristic of the device according to the invention, the means provided capable of detecting a reversal comprises

According to another additional characteristic of the device according to the invention, the mobile element and the means capable of immobilizing it cooperate with an element capable of slowing the movement of said mobile element.

Selon une autre caractéristique additionnelle du dispositif selon l'invention, l'élément apte à ralentir le déplacement de l'élément mobile consiste en un liquide qui remplit le moyen d'immobilisation de l'élément mobile, et dans lequel est immergé ledit élément mobile.  According to another additional characteristic of the device according to the invention, the element capable of slowing down the movement of the mobile element consists of a liquid which fills the means for immobilizing the mobile element, and in which said mobile element is immersed .

Selon une autre caractéristique additionnelle du dispositif selon l'invention, le moyen d'immobilisation de l'élément mobile consiste en un logement dont au moins les parois latérales correspondant aux côtés de l'engin agricole, s'évasent vers le haut, tandis que l'élément mobile présente une forme sphérique.  According to another additional characteristic of the device according to the invention, the means for immobilizing the mobile element consists of a housing of which at least the side walls corresponding to the sides of the agricultural machine, widen upwards, while the movable element has a spherical shape.

Selon un mode de réalisation particulier du dispositif selon l'invention, le logement se présente sous la forme d'un cône. According to a particular embodiment of the device according to the invention, the housing is in the form of a cone.

Selon une caractéristique additionnelle du dispositif selon l'invention, le signal apte à commander la mise en oeuvre d'un moyen d'émission d'un signal de détresse, est émis par des moyens électriques ou magnétiques. According to an additional characteristic of the device according to the invention, the signal capable of controlling the implementation of a means for transmitting a distress signal, is transmitted by electrical or magnetic means.

Selon une caractéristique additionnelle du dispositif selon l'invention, le moyen d'émission d'un signal de détresse consiste en un moyen d'émission d'un signal sonore et/ou lumineux. According to an additional characteristic of the device according to the invention, the means for transmitting a distress signal consists of a means for transmitting a sound and / or light signal.

Les avantages et les caractéristiques du dispositif selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif. The advantages and characteristics of the device according to the invention will emerge more clearly from the description which follows and which relates to the appended drawing, which represents a non-limiting embodiment thereof.

Dans le dessin annexé : - la figure 1 représente une vue schématique d'un dispositif de signalisation du retournement d'un engin agricole du type tracteur enjambeur. In the appended drawing: FIG. 1 represents a schematic view of a device for signaling the overturning of an agricultural machine of the straddle tractor type.

- la figure 2 représente une vue schématique du même dispositif lors d'un retournement. - Figure 2 shows a schematic view of the same device during a reversal.

En référence à la figure 1, on peut voir un dispositif de signalisation du retournement d'un engin agricole du type tracteur enjambeur selon l'invention. With reference to FIG. 1, one can see a device for signaling the overturning of an agricultural machine of the straddle tractor type according to the invention.

Ce dispositif comprend un élément mobile 1 maintenu par un moyen d'immobilisation 2, ainsi qu'un moyen 3 d'émission d'un signal de détresse.  This device comprises a mobile element 1 held by an immobilizing means 2, as well as a means 3 for transmitting a distress signal.

Le moyen mobile 1 consiste en une bille, tandis que le moyen d'immobilisation consiste en un récipient ou un logement présentant une forme sensiblement conique, c'est-à-dire qu'il comporte un fond 20 permettant de loger étroitement, éventuellement de manière congruente, la bille 1, ainsi que des parois 21 allant en s'évasant vers le haut.  The movable means 1 consists of a ball, while the immobilization means consists of a container or a housing having a substantially conical shape, that is to say that it has a bottom 20 making it possible to house tightly, possibly congruent, the ball 1, as well as walls 21 flaring upward.

Le logement 2 est fermé supérieurement par une cloison 22, et est équipé d'un moyen 4 de déclenchement d'un signal apte à commander la mise en oeuvre du moyen 3 d'émission d'un signal de détresse.  The housing 2 is closed above by a partition 22, and is equipped with a means 4 for triggering a signal capable of controlling the implementation of the means 3 for transmitting a distress signal.

Le moyen 4 de déclenchement consiste en un interrupteur se présentant sous la forme de deux contacts 40 et 41, reliés au moyen 3 d'émission, l'un disposé sur la face interne de la cloison 22 et l'autre sur la face interne des parois 20, en sorte que la bille 1, qui dans ce cas est réalisée en un matériau conducteur, puisse The triggering means 4 consists of a switch in the form of two contacts 40 and 41, connected to the transmission means 3, one disposed on the internal face of the partition 22 and the other on the internal face of the walls 20, so that the ball 1, which in this case is made of a conductive material, can

<Desc/Clms Page number 4> <Desc / Clms Page number 4>

fermer le circuit en touchant simultanément les deux contacts, lorsque le logement 2 est couché, et que par conséquent l'engin tracteur a basculé, comme cela est représenté sur la figure 2. close the circuit by simultaneously touching the two contacts, when the housing 2 is lying down, and therefore the towing machine has tilted, as shown in FIG. 2.

La fermeture du circuit a pour conséquence le déclenchement du moyen 3 d'émission d'un signal de détresse qui peut être une sirène par exemple. The closure of the circuit results in the triggering of the means 3 for transmitting a distress signal which can be a siren for example.

On notera que le moyen de déclenchement peut présenter d'autres formes, il peut ainsi consister, à titre d'exemple non limitatif, en un interrupteur que la bille vient actionner par l'effet de son poids.  It will be noted that the triggering means can have other forms, it can thus consist, by way of nonlimiting example, in a switch which the ball comes to actuate by the effect of its weight.

On notera également que de préférence il est prévu que la fermeture du circuit soit uniquement un déclencheur, en sorte que l'ouverture de ce circuit n'inhibe pas le moyen 3 d'émission, afin de poursuivre l'émission du signal de détresse même si, dans le cas d'un tonneau par exemple, l'engin tracteur, et donc le logement 2, reprend position sur ses roues.  It will also be noted that it is preferably provided that the closing of the circuit is only a trigger, so that the opening of this circuit does not inhibit the transmission means 3, in order to continue the transmission of the distress signal even if, in the case of a barrel for example, the towing vehicle, and therefore the housing 2, resumes its position on its wheels.

De manière avantageuse, le logement 2 est rempli d'un liquide L permettant d'amortir les déplacements de la bille 1, c'est-à-dire d'éviter que les secousses engendrées par les inégalités du terrain ne provoquent le déplacement de la bille 1 et la fermeture du circuit. Advantageously, the housing 2 is filled with a liquid L making it possible to dampen the movements of the ball 1, that is to say to prevent the jolts generated by the unevenness of the ground from causing the displacement of the ball 1 and closing the circuit.

Dans le cas d'un moyen 4 de déclenchement utilisant du courant électrique, il convient bien entendu que le liquide soit diélectrique. In the case of a trigger means 4 using electric current, it should of course be that the liquid is dielectric.

Une autre caractéristique de l'invention consiste en ce que le dispositif de signalisation du retournement est complété par un moyen prévu apte à détecter un choc subi par ledit engin agricole.  Another characteristic of the invention consists in that the device for signaling the overturning is supplemented by a means provided capable of detecting a shock suffered by said agricultural machine.

Ce moyen de détection de choc est, d'une part, couplé audit dispositif de signalisation du retournement et, d'autre part, apte à déclencher un signal apte à commander la mise en oeuvre d'un moyen d'émission d'un signal de détresse. This shock detection means is, on the one hand, coupled to said reversal signaling device and, on the other hand, capable of triggering a signal capable of controlling the implementation of a signal transmission means. of distress.

Il va de soi que la présente invention ne saurait être limitée à la description qui précède de l'un de ses modes de réalisation, susceptible de subir quelques modifications sans pour autant sortir du cadre de l'invention. It goes without saying that the present invention cannot be limited to the foregoing description of one of its embodiments, capable of undergoing some modifications without departing from the scope of the invention.

<Desc/Clms Page number 5> <Desc / Clms Page number 5>

Ainsi, outre différentes formes de réalisation du moyen 4 de déclenchement, le moyen d'émission d'un signal de détresse peut se présenter de différentes manières, il peut ainsi consister en l'émission d'un signal radio ou analogue, et/ou en l'envoi de fusées de détresse, et/ou la mise en fonctionnement d'un gyrophare. Thus, in addition to different embodiments of the triggering means 4, the means for transmitting a distress signal can be presented in different ways, it can thus consist in the emission of a radio signal or the like, and / or by sending distress flares, and / or putting a beacon into operation.
