Abstract

The device has a platform frame with a lever arm articulated at its base. A self-blocking winch without dead center is fixed at top of the arm to raise a tilting frame to free up a space, with automatic deployment of a safety stay base. The base is blocked on the tilting frame by a pin. A cable is limited for placing the base at height lower than critical balancing threshold. Wheels on the platform frame permit to move the device.

Description

La présente invention concerne un dispositif pour lever latéralement uneThe present invention relates to a device for lifting a

tondeuse auto-portée afin de nettoyer le cache lames et d'accéder aux lames.  mower is self-supporting to clean the blade cover and access the blades.

Cette invention est innovante par l'utilisation d'un treuil autobloquant, sans point mort, pour la levée ou la descente avec déploiement automatique d'un pied chandelle de sécurité 5 Il existe sur le marché deux systèmes, l'un composé d'un berceau pour les roues avant avec levier basculant, agissant par levée frontale, l'autre par levée latérale avec une vis sans fin.  This invention is innovative by the use of a self-locking winch, without dead point, for lifting or lowering with automatic deployment of a safety stand 5 There are two systems on the market, one consisting of a cradle for the front wheels with rocking lever, acting by frontal lift, the other by side lift with a worm.

Le dispositif tubulaire acier selon l'invention permet de basculer latéralement une tondeuse auto-portée, composé de deux cadres articulés sur une des largeurs par tube dans tube, le 10 cadre plate-forme est équipé d'un bras levier articulé à sa base sur la largeur du cadre par tube dans tube, au sommet de ce bras levier est fixé un treuil autobloquant à levée- descente sans point mort, le câble et son crochet sont fixé sur le cadre basculant, l'action sur le treuil, lève le cadre basculant (après y avoir placé deux roues de la tondeuse) au fur et à mesure de la levée, le pied de sécurité descend, en fin de course du câble, le pied est en 15 position verticale, une goupille le bloque, cette hauteur fixe déterminée est inférieure au seuil critique de gravité.  The steel tubular device according to the invention makes it possible to tilt a self-supported mower laterally, composed of two frames articulated on one of the widths per tube in tube, the platform frame is equipped with a lever arm articulated at its base on the width of the frame by tube in tube, at the top of this lever arm is fixed a self-locking winch lift-descent without dead point, the cable and its hook are fixed on the tilting frame, the action on the winch, lifts the frame tilting (after having placed two wheels of the mower) as and when lifting, the safety foot down at the end of the cable run, the foot is in the vertical position, a pin blocks, this fixed height determined is below the critical severity threshold.

Le bras levier articulé à sa base accompagne dans la courbe crée lors de la montée le cadre basculant.  The lever arm articulated at its base accompanies in the curve created during the rise the swinging frame.

Deux anneaux sont sur le cadre basculant pour attacher la tondeuse.  Two rings are on the tilting frame to attach the mower.

La course du treuil, lève le cadre basculant, dégageant ainsi un espace pour accéder aux lames sous la tondeuse.  The winch stroke lifts the tilting frame, freeing up space for access to the blades under the mower.

Pour la descente il suffit d'ôter la goupille de blocage de pied de sécurité et de manoeuvrer le treuil en descente.  For the descent simply remove the safety foot locking pin and operate the winch downhill.

Deux roulettes sur le cadre plate-forme permettent de déplacer l'ensemble sans effort.  Two wheels on the platform frame allow you to move the set effortlessly.
