Abstract

The pruning tool has a tempered steel toothed blade (3) which is operated by a mobile arm (2). The arm is connected at the top to one end of a helical spring (5) connected at the other end to a driving element (6). The mobile arm is pivoted to a fixed arm (1) formed in a V-shape to retain the branch being cut between the two limbs. The two arms are connected by a steel pivot pin (4).

Description

Procédé pour élaguage des branches d'arbres, facilite la coupe de certaines branches d'un diamètre trop important pour l'utilisation d'un sécateur, et inaccessible à la scie. Process for pruning tree branches, facilitates the cutting of certain branches with a diameter too large for the use of pruning shears, and inaccessible to the saw.

Procédé rendant très facile la coupe des grosses branches avec un effort extrêmement réduit. A process that makes it very easy to cut large branches with extremely little effort.

L'outil, objet de la présente invention, est remarquable en ce qu'il évite l'utilisation d'une tronçonneuse câuteuse et d'un emploi quelquefois délicat, encombrement, poids. The tool, object of the present invention, is remarkable in that it avoids the use of a coarse chainsaw and sometimes delicate use, size, weight.

Une forme d'exécution de l'invention est décrite ciaprès à titre indicatif et nullement limitatif en se référant au dessin annexé. An embodiment of the invention is described below by way of indication and in no way limitative with reference to the attached drawing.

La figure représente une perspective cavalière de l'outil. The figure shows a perspective view of the tool.

Le dispositif est constitué d'une lame de scie à denture bois en acier trempé 3, fixée au bras mobile en tôle emboutie pliée 2, par l'intermédiaire d'un axe en acier 7. La pénétration de la lame dans la branche est assurée par un poussoir 6; qui assure une pression constante sur celle-ci à l'aide d'un ressort de traction 5, ce poussoir étant articulé qur un axe en acier 9. Deux trous 8, l'un au poussoir 9, l'autre au bras mobile 2, permettent la fixation du ressort. The device consists of a hard-toothed steel serrated saw blade 3, fixed to the movable arm of folded pressed sheet metal 2, by means of a steel pin 7. The penetration of the blade into the branch is ensured by a pusher 6; which ensures constant pressure on the latter using a tension spring 5, this pusher being articulated only on a steel pin 9. Two holes 8, one in the pusher 9, the other in the movable arm 2 , allow the spring to be fixed.

La partie supérieure du bras fixe en tôle emboutie pliée 1, destiné à recevoir la branche, comporte une empreinte en forme de V pour maintenir la branche en position de sciage. Ce bras 1 est fixé au bras 2 par l'intermédiaire d'un axe en acier 4. The upper part of the fixed arm of folded stamped sheet metal 1, intended to receive the branch, has a V-shaped imprint to hold the branch in the sawing position. This arm 1 is fixed to the arm 2 by means of a steel pin 4.

I1 est bien entendu que la présente invention n'est pas limitée au mode de réalisation décrit et représenté qui constitue seulement un exemple auquel de nombreuses modifications peuvent etre apportées sans que l'on s'écarte de la présente invention. Notamment pour la coupe à des hauteurs plus élevées, sans l'aide d'une échelle; et la coupe au sol des buches destinées aux cheminées à feu de bois par exemple.  I1 is understood that the present invention is not limited to the embodiment described and shown which is only an example to which many modifications can be made without departing from the present invention. Especially for cutting at higher heights, without using a ladder; and the cutting on the ground of logs intended for fireplaces with wood fire for example.
