Abstract
Description
La présente invention concerne un système qui permet de tronçonner le bois de toutes dimensions et toutes sortes, en toute sécurité, par un autn-blocage del'ensemble: chevalet et bois. The present invention relates to a system that makes it possible to cut the wood of all dimensions and all kinds, in complete safety, by a self-locking assembly: easel and wood.
Lorsque l'on utilise'une tronçonneuse, le bois étant difforme, vert, sec, dur, cela donne des à-coups à l'attaque du bois, celui-ci n'étant pas solidement bloqué entre les croisillons du chevalet, on se trouve obligé dele maintenir avec la main ou le pied. When you use a chainsaw, the wood being deformed, green, dry, hard, it gives jolts to attack the wood, it is not securely blocked between the braces of the bridge, it is find it necessary to keep it with the hand or the foot.
1 ) Immobilisation de la main gauche, il ne reste que la main droite pour maintenir la tronçonneuse "DANGER" 2") Immobilisation.avec la jambe et le pied an appui sur le bois et le chevalet, risque de désequilibre de l'utilisateur, risque de renverser l'ensemble DANGER
Le système selon linvention permet de remédier à ces ris ques. I1 comporte un chevalet muni d'une chaine ou un cable maintenant le bois ou autres matériaux à tronçonner, le tout étant bloqué en appuyant avec le pied sur une pédale, le chevalet lui-même faisant corps avec le sol grace aux sabots: griffes pour sol mou, patins ou ventouses en caoutchouc pour sol dur; ce qui donne une grande sécurité, liberté des mains, parfaite stabilité aucun renversement de l'ensemble.1) Immobilization of the left hand, only the right hand remains to maintain the chainsaw "DANGER" 2 ") Immobilisation.with the leg and the foot a support on the wood and the easel, risk of imbalance of the user, risk of reversing the whole DANGER
The system according to the invention makes it possible to remedy these risks. I1 includes a bridge with a chain or a cable holding the wood or other cutting materials, all being blocked by pressing with the foot on a pedal, the bridge itself forming with the ground thanks to the hooves: claws for soft ground, rubber pads or suction cups for hard ground; which gives great security, freedom of the hands, perfect stability no reversal of the whole.
Dans sa partie supérieure, 1'X du chevalet forme un angle de 90 , ce qui lui donne une grande capacité. Les V métalliques ont pour première utilité d'empêcher le bois de basculer lorsqu'il est tronçonné, de ce fait, la chatne de la tronçonneuse n'est jamais coincée entre les deux morceaux de bois coupés et pour seconde, de permettre de tronçonner les Dois de petites dimensions en les mailltenant soit droite soit à gauche. In its upper part, the X of the bridge forms an angle of 90, which gives it a large capacity. The main purpose of V metal is to prevent the wood from tipping when cut, so that the chainsaw's cat is never wedged between the two pieces of cut wood and, for a second time, to cut the logs. Have small dimensions by keeping them either right or left.

Le système représenté sur la figure 1 est unnstitué par un chevalet (C) équipé d'une chatne (2) munie de griffes (3) ayant d'une part son point d'attache sur un anneau (4) pouvant se déplacer latéralement sur la traverse (5) du chevalet (C) et d'autre part sur ellemeame par un crochet (14) en un point différent selon la grosseur du bois, la chaine (2) contourne l'axe (13) dans une encoche (12) de la pédale (7). Ceci permet de donner un réglage en hauteur de la pédale t7). L'arrière de la pédale (7) est en appui sur la traverse (10). The system represented in FIG. 1 is represented by an easel (C) equipped with a cat (2) provided with claws (3) having, on the one hand, its point of attachment on a ring (4) able to move laterally on the crossbar (5) of the bridge (C) and secondly on ellemeame by a hook (14) at a different point depending on the size of the wood, the chain (2) bypasses the axis (13) in a notch (12). ) of the pedal (7). This makes it possible to give a height adjustment of the pedal t7). The rear of the pedal (7) is supported on the cross member (10).
Dans ce système les montants du chevalet (C) de part et d'autre sont articulés sur un axe (15) et forment entre eux dans la partie supérieure, un angle de 900, ce qui donne une grande ouverture. A 11 intérieur des montants, à gauche et à droite, sur l'axe (15) est fixé un V (11). La longueur des V (11) varie et est limitée par la largeur du chevalet (6), un vide entre eux étant nécessaire pour effectuer les coupes. Les traverses (5) sont soudées sur chaque montant deux à deux, en dessous du point de croisement, à une hauteur donnée, pour que l'on ne soit pas gêné en fin de coupe. Les traverses (10) sont soudées sur chaque montant deux à deux, à la base, au dessus des sabots t8) à une hauteur donnée. Les traverses (5) et (10) assurent la rigidité de l'ensemble. In this system the amounts of the bridge (C) on both sides are articulated on an axis (15) and form between them in the upper part, an angle of 900, which gives a large opening. Inside the uprights, to the left and to the right, on the axis (15) is fixed a V (11). The length of the V (11) varies and is limited by the width of the bridge (6), a gap between them being necessary to perform the cuts. The sleepers (5) are welded to each post two by two, below the cross point, at a given height, so that one is not embarrassed at the end of cutting. The sleepers (10) are welded to each upright two by two, at the base, above the shoes t8) at a given height. The sleepers (5) and (10) ensure the rigidity of the assembly.
L'écartement du chevalet (6) est limité à la base par les chatnes métalliques à maillons (9). The spacing of the bridge (6) is limited at the base by the metal link catches (9).
Dans la figure 2 1 bois à tronçonner est de petite dimension, il est dans le V (11); la chaîne (2) et la pédale (7) ont été déplacées, l'auto-blocage de l'ensemble est assuré.-
Ce système selon l'invention est particulièrement destiné à tronçonner le bois. In Figure 2 1 cutting timber is small in size, it is in the V (11); the chain (2) and the pedal (7) have been moved, the self-locking of the assembly is ensured.-
This system according to the invention is particularly intended to cut the wood.
