Description
CHEVALET METALLIQUE POUR COUPE DE BUCHES
AVEC MAINTIEN AUTOMATIQUE
La présente invention concerne un systéme de maintien automatique simple , efficace et sûr d'une bûche sur un chevalet métallique pour une coupe à la scie ou à la tron donneuse.METAL FRAME FOR LOG CUTTING
WITH AUTOMATIC HOLD
The present invention relates to a simple, effective and safe automatic holding system of a log on a metal easel for cutting with a saw or a donor section.
Traditionnellement , la coupe d'une bûche sur chevalet nécessite l'intervention d'une seconde personne qui maintien la bûche à l'aide des deux mains.Cette personne est exposée à de nombreux accidents , notamment le glissement de la lame sur la bûche ce qui peut provoquer la coupure de doigts , voire de la main , entraînant parfois un handicap à vie. Traditionally, the cutting of a log on an easel requires the intervention of a second person who holds the log using two hands. This person is exposed to numerous accidents, in particular the sliding of the blade on the log. which can cause fingers or even the hand to be cut, sometimes resulting in lifelong disability.
La présente invention consiste en un systéme de maintien de la bûche par une lame de blocage dentée qui épouse le diamétre de la bûche, quelle soit petite ou grosse.La lame de blocage coulissant par deux bagues situées à ses extrémités sur deux guides métalliques est maintenue par deux ressorts à étirement.L'action du sciage - à la tronçonneuse ou à la main - provoque le blocage des bagues coulissantes sur le guide-lame de blocage , selon le principe de la chevilette de maçon.La lame se decoince et se souléve par une simple pression du doigt exercée sur une poignée. The present invention consists of a system for holding the log by a toothed blocking blade which matches the diameter of the log, whether small or large. The blocking blade sliding by two rings situated at its ends on two metal guides is held by two stretching springs. The action of sawing - with a chainsaw or by hand - causes the sliding rings to be blocked on the blocking guide blade, according to the principle of the mason's bolt. The blade loosens and lifts by a simple finger pressure on a handle.
Ce systéme envient aux droitiers et aux gauchers. This system envies right and left handed users.
En référence à ces dessins , le dispositif ~UuHvLte un guide-lame de blocage(1)constitué d'un support gétallique horizontal et de deux guides ronds en acier étirè sur lesquels coulisse une lame de blocage(2)dentée munie d'une poignée.La lame de blocage) est rendue solidaire duguide-lame de blocage (1) par deux ressorts à étirement(3).Le chevalet(5) est muni d'un support de bûche constitué d'une corniéret4).Tout l'assemblage est effectué par soudure à l'arc.With reference to these drawings, the device ~ UuHvLte a blocking blade guide (1) consisting of a horizontal metal support and two round drawn steel guides on which slides a toothed blocking blade (2) provided with a handle. .The locking blade) is made integral with the locking blade guide (1) by two stretching springs (3). The easel (5) is provided with a log support made up of a corniéret4). is performed by arc welding.
Sur le chevalet,la mise en place de la bûche s'effectue aprés le soulévement de la lame de blocage(2)par l'intermédiaire de sa poignée.Une fois la bûche placée sur son support constitué d'une corniére profilée de 50x50(4),les ressorts(-3)plaquent la lame de blocage(2)sur la bûche sur simple relâchement de la poignée.L1action du sciage - manuel ou à la tronçonneuse provoque instantanément le blocage des bagues coulissantes situées aux extrémités de la lame de blocage(2)sur le guide lame de blocage(1).La corniére(4)permet la coupe de bûches de faibles longueurs
Le dispositif selon l'invention est particuliérement adapté à un usage domestique ; il est stable , maniable léger et surtout sûr car il laisse les mains libres à l'utilisateur.Il permet en outre la coupe de bûches de faibles longueurs. On the easel, the log is put in place after the blocking blade (2) is lifted by its handle. Once the log is placed on its support consisting of a 50x50 profiled angle ( 4), the springs (-3) press the blocking blade (2) on the log by simply releasing the handle. The action of sawing - manual or with a chainsaw instantly causes the sliding rings at the ends of the blade to block blocking (2) on the blocking blade guide (1). The angle (4) allows the cutting of short logs
The device according to the invention is particularly suitable for domestic use; it is stable, easy to handle and above all safe because it leaves the user free of hands and allows the cutting of short logs.
