Abstract

The telescopic seat is for a tractor. A hydraulic telescopic ram, double or single acting, has five elements made of steel. These have a total travel of 2 metres and the last has a flexible spring bolted to allow bolting of a seat with two handgrips. The assembly includes a spherical 10cm diameter ball in three parts, held by three bolts. This only moves when subjected to high pressure. The ball is welded between the ram base and the platform to avoid shocks due to rigidity.

Description

DESCRIPTI0N
Dans ces domaines de l'industrie il y eut d'importants progrés de la technique, cela est remarquable mais, l'on a totalement exclu la protection de 1'homme car, depuis que les traoteurs, machines agricoles, pelles-mécani ques existent des milliers d'hommes en France ont trouvé la mort par écrasement. A ce jour, il n'y a aucun tracteur, machine agricole et pelle-mécanique français ou étranger doté d'un tel appareil de protection qui mettrait hors de danger lthomme dans le cas d'un versement d'un de ces engins.DESCRIPTI0N
In these areas of industry there have been significant technical advances, this is remarkable but, the protection of man has been totally excluded since, since traders, agricultural machines, excavators have existed thousands of men in France were killed by crushing. To date, there is no tractor, agricultural machine and shovel mechanic French or foreign equipped with such a protective device which would put man out of danger in the event of a payment of one of these machines.

A l'aide du " siège télescopique " objet de la présente Invention le conducteur de tracteur ou engin sera hors de danger puisque lors deun versement de l'engin de quel côté qu'il se fasse le conducteur se trouvera en quelques seoondes à 2 mètres de son engin donc, il aura évité l'écrasement.With the help of the "telescopic seat" which is the subject of the present invention, the driver of the tractor or machine will be out of danger since, when the machine is poured, whichever side it is on, the driver will be in a few seconds at 2 meters of his machine therefore, he will have avoided the crash.

Figure 3. " Le siège télescopique " est caractérisé par un vérin hydraulique bisoté a la base Figure I- de 40 centimètres d'impact et de 10 centimetres de diamètre il comporte 5 éléments en acier 1.2.3.4.5. au sommet du 5 ème élément se trouve une plaque en acier de 10 x 10 centimètres 6 soudée sur laquelle est boulonné un ressort flexible 7- qui permettra de boulonner le siège avec 2 poignées 8-.Une rotule sphérique Figure 4- de 10 centimètres de diamètre fabriquée en 3 pièces réglé par 3 boulons afin qu'elle ne puisse se mouvoir que par une forte pression, la rotule sera soudée à l'arc entre le vérin Figure I- et la plate-forme 9- rectangulaire de 20 x 30 centimètres oe qui permettra au " siège télescopique " d'épouser les pentes et fossés dans le but d'éviter le moindre choc au conducteur
Figure 3-. Dans l'hypothèse d'un autre genre d'accident la où le tracteur agricole, pelle mécanique pourrait " culbuter " dans un fossé large et profond dans ce cas le " siège télescopique " ferait office de béquille et se planterait au sol -(toujours à 2 mètres dn tracteur ou pelle mécanique)et freinerait considérablement l'engin . Ainsi, le conducteur aura le temps de se lever de son"siège télescopique" et s'éloigner pour être hors de portée de l'écrasement. Le " siège télescopique n ne demande pas d'enómbre- ment supplémentaire au delà du siege boulonné qui existe actuellement. Son fonctionnement est aisé étant donné que les tracteurs et engins sont munis d'une pompe hydraulique de 200 3ars avec un raccordement supplémentaire.Figure 3. "The telescopic seat" is characterized by a hydraulic cylinder tilted at the base Figure I- 40 centimeters of impact and 10 centimeters in diameter it has 5 steel elements 1.2.3.4.5. at the top of the 5th element is a welded 10 x 10 cm steel plate 6 on which is bolted a flexible spring 7- which will allow the seat to be bolted with 2 handles 8-. A 10 cm spherical ball joint Figure 4- diameter manufactured in 3 pieces adjusted by 3 bolts so that it can only move by strong pressure, the ball will be welded to the arc between the jack Figure I- and the platform 9- rectangular of 20 x 30 centimeters oe which will allow the "telescopic seat" to follow the slopes and ditches in order to avoid any shock to the driver
Figure 3-. In the event of another kind of accident where the agricultural tractor, mechanical shovel could "tumble" in a wide and deep ditch in this case the "telescopic seat" would act as a crutch and crash to the ground - (always 2 meters from a tractor or mechanical shovel) and would considerably brake the vehicle. Thus, the driver will have time to get up from his "telescopic seat" and move away to be out of reach of the crash. The "telescopic seat does not require additional space beyond the bolt-on seat which currently exists. Its operation is easy since the tractors and machines are provided with a hydraulic pump of 200 3ars with an additional connection.

Le débit devra être réglé selon la vitesse nécessaire au fonctionnement du " siège télescopique The flow rate must be adjusted according to the speed necessary for the operation of the "telescopic seat
